BACKGROUND: The main treatment modality for gastric cancer is surgical resection with lymphadenectomy. Despite advances in perioperative care, major surgical complications can occur in up to 20% of cases. To determine the quality of surgical care employed, a new indicator called failure to rescue (FTR) was proposed, which assesses the percentage of patients who die after complications occur. AIMS: To assess the rate of FTR after gastrectomy and factors associated with its occurrence. METHODS: Patients with gastric cancer who underwent gastrectomy with curative intent were retrospectively evaluated. According to the occurrence of postoperative complications, patients were divided into FTR group (grade V complications) and rescued group (grade III/IV complications). RESULTS: Among the 731 patients, 114 had major complications. Of these patients, 76 (66.7%) were successfully treated for the complication (rescued group), while 38 (33.3%) died (FTR group). Patients in the FTR group were older (p=0.008; p<0.05), had lower levels of hemoglobin (p=0.021; p<0.05) and albumin (p=0.002; p<0.05), and a higher frequency of ASA III/IV (p=0.033; p<0.05). There were no differences between the groups regarding surgical and pathological characteristics. Clinical complications had a higher mortality rate (40.0% vs 30.4%), with pulmonary complications (50.2%) and infections (46.2%) being the most lethal. Patients with major complications grade III/IV had worse survival than those without complications. CONCLUSIONS: The FTR rate was 33.3%. Advanced age, worse performance, and nutritional parameters were associated with FTR.

BACKGROUND: Previous studies have shown a relationship between calf circumference (CC) and outcomes in hospitalized patients. AIMS: To investigate the relationship between CC and clinical and nutritional outcomes in older in-patients (OiP) in a surgery ward. METHODS: This was a cross-sectional study with 417 OiP in a surgery ward. Clinical variables, anthropometry, and nutritional screening instruments such as subjective global assessment (SGA), mini nutritional assessment (MNA), and nutritional risk screening (NRS) were used in the investigation. The tests Pearson's chi-square, Mann-Whitney, Kruskal-Wallis, and Spearman's coefficient, and multiple linear regression analyses were used to review the factors associated with CC. RESULTS: Lower CC values were found in the age group 80 years and over (p<0.0001), presence of complications (p=0.0269), NRS (p<0.0001), SGA (p<0.0001), and MNA (p<0.0001). Gender (p=0.0011; partial R2=0.01151), age (p=0.0002; partial R2=0.06032), body mass index (p≤0.0001; partial R2=0.40820), and arm circumference (p≤0.0001; partial R2=0.11890) are variables that together were associated with CC. There was also a relationship between SGA (p=0.0166; partial R2=0.00605) and absence of complications during hospitalization (p=0.0047; R2=0.01154) with CC. CONCLUSIONS: Gender, age, body mass index, and arm circumference were jointly associated with CC, in addition to SGA and absence of complications. The CC is a relevant indicator for OiP in the clinical practice.

BACKGROUND: Para-aortic lymph nodes involvement in pancreatic head cancer has been described as an independent adverse prognostic factor. To avoid futile pancreatic resection, we systematically perform para-aortic lymphadenectomy as a first step. AIMS: To describe our technique for para-aortic lymphadenectomy. METHODS: A 77-year-old female patient, with jaundice and resectable pancreatic head adenocarcinoma, underwent pancreaticoduodenectomy associated with infracolic lymphadenectomy. RESULTS: The infracolic anterior technique has two main advantages. It is faster and prevents the formation of postoperative adhesions, which can make subsequent surgical interventions more difficult. CONCLUSIONS: We recommend systematic para-aortic lymphadenectomy as the first step of pancreaticoduodenectomy for pancreatic head adenocarcinoma by this approach.

BACKGROUND: Part of colorectal cancer cases occurs due to modifications in the DNA mismatch repair system, which are responsible for microsatellite instability. This alteration results in an unconventional phenotypic pattern of colorectal cancer. AIMS: To describe the epidemiological, histopathological and molecular profiles of patients with colorectal cancer who underwent surgical treatment in a reference hospital. METHODS: This is a cross-sectional, retrospective study with a quantitative approach, that included a review of patients' medical records who underwent oncological surgery for colorectal cancer. RESULTS: A total of 122 colorectal cancer cases were identified, with microsatellite instability detected in 8.2% of the sample. The gender distribution was similar, with 52.46% males, and the weighted average age was 63 years (standard deviation±11.65). However, in the microsatellite instability group, the predominant age was below 60 years. Regarding the histological type, adenocarcinoma not otherwise specified accounted for 80.33% of the cases, being the most prevalent in both groups, with the mucinous type being more frequent among the instability cases. The pT3 pathological staging (46.72%) was the most predominant. The topography was more prevalent on the left (60.66%), but there was a significant difference when compared to the group with microsatellite instability, in which 80% of the neoplasms were located on the right (p=0.006). CONCLUSIONS: Differences in age and neoplastic topography found in microsatellite instability samples highlight the distinctive presentation pattern of the disease. Recognizing these characteristics is essential for developing prevention strategies, in addition to early and accurate diagnosis of colorectal cancer.

BACKGROUND: Despite major advances in the clinical treatment of inflammatory bowel disease, some patients still present with acute colitis and require emergency surgery. AIMS: To evaluate the risk factors for early postoperative complications in patients undergoing surgery for acute colitis in the era of biologic therapy. METHODS: Patients with inflammatory bowel disease admitted for acute colitis who underwent total colectomy at a single tertiary hospital from 2012 to 2022 were evaluated. Postoperative complications were graded according to Clavien-Dindo classification (CDC). Patients with more severe complications (CDC≥2) were compared with those with less severe complications (CDC<2). RESULTS: A total of 46 patients underwent surgery. The indications were: failure of clinical treatment (n=34), patients' or surgeon's preference (n=5), hemorrhage (n=3), toxic megacolon (n=2), and bowel perforation (n=2). There were eight reoperations, 60.9% of postoperative complications classified as CDC≥2, and three deaths. In univariate analyses, preoperative antibiotics use, ulcerative colitis diagnosis, lower albumin levels at admission, and preoperative hospital stay longer than seven days were associated with more severe postoperative complications. CONCLUSIONS: Emergency surgery for acute colitis was associated with a high incidence of postoperative complications. Preoperative use of antibiotics, ulcerative colitis, lower albumin levels at admission, and delaying surgery for more than seven days were associated with more severe early postoperative complications. The use of biologics was not associated with worse outcomes.

BACKGROUND: The prevalence of primary sclerosing cholangitis (PSC) in the general population has not yet been clearly established. The management of PSC should focus on delaying the progression of the disease and restraining its complications. The only curative therapy for the disease remains liver transplantation (LT). PSC is currently the fifth most common indication for LT and corresponds to 5% of all LT indications in adults. AIMS: Our objective is to evaluate the indications and outcomes of PSC patients undergoing LT in three liver transplantation centers in southern Brazil - Hospital Santa Isabel in Blumenau, Santa Catarina state, and Hospital das Clínicas and Hospital Nossa Senhora das Graças, in Curitiba, Parana state). METHODS: This is a longitudinal observational study of patients with PSC who underwent LT in three major Brazilian medical centers. Electronic medical records and study protocols of all patients subjected to LT from January 2011 to December 2021 were retrospectively reviewed. RESULTS: Of the 1,362 transplants performed in the three medical centers, 37 were due to PSC. Recurrence of PSC occurred in three patients (8.1%) in 3.0±2.4 years (range, 1-4 years). The 1-year and 5-year survival rates after the first LT were 83.8 and 80.6%, respectively. The 1-year and 5-year graft survival rates were, respectively, 83.8 and 74.8%. CONCLUSIONS: Our experience with LT in patients with PSC demonstrated good patient and graft survival results. Most deaths were due to common factors in patients undergoing LT.

BACKGROUND: Gastric neuroendocrine tumors are a heterogeneous group of neoplasms that produce bioactive substances. Their treatment varies according to staging and classification, using endoscopic techniques, open surgery, chemotherapy, radiotherapy, and drugs analogous to somatostatin. AIMS: To identify and review cases of gastric neuroendocrine neoplasia submitted to surgical treatment. METHODS: Review of surgically treated patients from 1983 to 2018. RESULTS: Fifteen patients were included, predominantly female (73.33%), with a mean age of 55.93 years. The most common symptom was epigastric pain (93.3%), and the mean time of symptom onset was 10.07 months. The preoperative upper digestive endoscopy (UDE) indicated a predominance of cases with 0 to 1 lesion (60%), sizing ≥1.5 cm (40%), located in the gastric antrum (53.33%), with ulceration (60%), and Borrmann III (33.33%) classification. The assessment of the surgical specimen indicated a predominance of invasive neuroendocrine tumors (60%), with angiolymphatic invasion in most cases (80%). Immunohistochemistry for chromogranin A was positive in 60% of cases and for synaptophysin in 66.7%, with a predominant Ki-67 index between 0 and 2%. Metastasis was observed in 20% of patients. The surgical procedure most performed was subtotal gastrectomy with Roux-en-Y reconstruction (53.3%). Tumor recurrence occurred in 20% of cases and a new treatment was required in 26.67%. CONCLUSIONS: Gastric neuroendocrine tumors have a low incidence in the general population, and surgical treatment is indicated for advanced lesions. The study of its management gains importance in view of the specificities of each case and the need for adequate conduct to prevent recurrences and complications.

BACKGROUND: Patients with obesity present multiple comorbid psychiatric conditions and experience impairments in health-related quality of life. Reliable and valid tools that evaluate health-related quality of life are essential for clinical practice. AIMS: This study aimed to investigate the reliability and validity of the six-item Moorehead-Ardelt Quality of Life Questionnaire II among Brazilian patients with severe obesity. METHODS: We assessed 387 patients (mean age 43 years, 78.8% women, mean body mass index of 46.5 kg/m²) on the waiting list of a bariatric surgery center. Trained research assistants concurrently applied the Moorehead-Ardelt Quality of Life-II, the Montgomery-Åsberg Depression Rating Scale, and the Global Assessment of Functioning for assessing health-related quality of life, comorbid depressive symptoms, and patient functioning level, respectively. RESULTS: The internal consistency of the Moorehead-Ardelt Quality of Life-II was considered acceptable. The total score was correlated with the severity of depressive symptoms and functioning level. The more body mass index increases, the more health-related quality of life worsens. The Moorehead-Ardelt Quality of Life-II presented a unidimensional structure. CONCLUSIONS: The unidimensional Moorehead-Ardelt Quality of Life-II is a reliable and valid measure for evaluating health-related quality of life in Brazilian patients with severe obesity. The questionnaire allows to quickly assess the health-related quality of life of patients in different bariatric contexts, considering depression and functional level.

BACKGROUND: In the surgical correction of large incisional hernias, the use of a prosthesis is essential in most cases regardless of the technique chosen. The preference is for the polypropylene prosthesis. AIMS: To compare the onlay and Rives-Stoppa techniques in the correction of incisional hernias, their immediate results, complications, advantages, and disadvantages. METHODS: Two groups of patients with incisional hernias were analyzed, submitted to the onlay (19 patients) and Rives-Stoppa (17 patients) techniques, and that used polypropylene prostheses. General epidemiological variables, perioperative data variables, and postoperative complications were assessed. RESULTS: The patients' epidemiologic profile was similar between both groups. The majority were women (58.4%), with a mean age of 65.5 years and a previous mean body mass index of 41.5 kg/m². The Rives-Stoppa technique was employed in most patients (52.7%). Those submitted to the onlay technique had longer abdominal drainage time and longer hospital stay, as well as a higher incidence of seromas and surgical wound infection. CONCLUSIONS: The incisional herniorrhaphy technique with the placement of a pre-peritoneal polypropylene mesh by the Rives-Stoppa technique was superior to the onlay due to lower rates of drain use, hospital stay, and postoperative complications.

BACKGROUND: Surgical antibiotic prophylaxis is an essential component of perioperative care. The use of prophylactic regimens of antibiotics is a well-established practice that is encouraged to be implemented in preoperative/perioperative protocols in order to prevent surgical site infections. AIMS: The aim of this study was to emphasize the crucial aspects of antibiotic prophylaxis in abdominal surgery. RESULTS: Antibiotic prophylaxis is defined as the administration of antibiotics before contamination occurs, given with the intention of preventing infection by achieving tissue levels of antibiotics above the minimum inhibitory concentration at the time of surgical incision. It is indicated for clean operations with prosthetic materials or in cases where severe consequences may arise in the event of an infection. It is also suitable for all clean-contaminated and contaminated operations. The spectrum of action is determined by the pathogens present at the surgical site. Ideally, a single intravenous bolus dose should be administered within 60 min before the surgical incision. An additional dose should be given in case of hemorrhage or prolonged surgery, according to the half-life of the drug. Factors such as the patient's weight, history of allergies, and the likelihood of colonization by resistant bacteria should be considered. Compliance with institutional protocols enhances the effectiveness of antibiotic use. CONCLUSION: Surgical antibiotic prophylaxis is associated with reduced rates of surgical site infection, hospital stay, and morbimortality.

BACKGROUND: Acute appendicitis is a common surgical emergency worldwide. Recent studies on hematological inflammatory markers concerning acute appendicitis have shown variable results. AIMS: The aim of this study was to evaluate pre-operative values of platelet indices such as mean platelet volume (MPV) and platelet distribution width (PDW), and red cell distribution width (RDW) in relation to the diagnosis of acute appendicitis and their efficacy as predictors of appendicular perforation. METHODS: A prospective observational study of 190 patients diagnosed with appendicitis and who underwent an appendectomy was undertaken and confirmed histopathologically. Preoperatively, blood samples of white blood cells (WBCs), platelet count, MPV, PDW, and RDW were analyzed using a Sysmex XN1000 analyzer machine. RESULTS: Of 190 patients, 169 had acute appendicitis, and 21 had perforated appendicitis. The mean age of patients was 28.04 ± 14.2 years. The male-to-female ratio was 1.5:1. The WBC (p<0.05), MPV (p<0.05), and PDW (p<0.05) were found to have higher statistically significant values in acute appendicitis and perforated appendicitis compared to the RDW (p>0.05). However, perforated appendicitis had a higher RDW value compared to acute appendicitis, which can be a predictive factor. CONCLUSIONS: The elevated value of MPV and PDW associated with leukocytosis can be used as supportive evidence for the clinical and radiological diagnosis of acute appendicitis and appendicular perforation. Thus, these values can be used as diagnostic cost-effective inflammatory biomarkers.

BACKGROUND: Bariatric surgery is the best treatment option for patients with obesity. As a result of the advancement of technology, the robotic gastric bypass presents promising results, despite its still high costs. AIMS: The aim of this study was to compare patients submitted to a robotic versus a laparoscopic gastric bypass at a single center by a single surgeon. METHODS: This retrospective study collected data from the medical records of 221 patients (121 laparoscopic procedures versus 100 with daVinci platform). The variables analyzed were sex, age, body mass index, comorbidities, surgical time, length of stay, and complications. RESULTS: The mean surgical time for patients in the robotic group was shorter (102.41±39.44 min versus 113.86±39.03 min, p=0.018). The length of hospital stay in robotic patients was shorter (34.12±20.59 h versus 34.93±11.74 h, p=0.007). There were no serious complications. CONCLUSIONS: The group submitted to the robotic method had a shorter surgical time and a shorter hospital stay. No difference was found regarding strictures, bleeding, or leakage.

Metastatic gastric cancer traditionally hinders surgical treatment options, confining them to palliative procedures. The presence of metastases in these tumors is classified as M1, irrespective of their characteristics, quantity, or location. However, oligometastatic disease emerged as an intermediate state between localized and widely disseminated cancer. It exhibits diverse patterns based on metastatic disease extent, type, and location. Adequately addressing this distinctive metastatic state necessitates tailored strategies that surpass the realm of palliative care. Differentprimary tumor types present discernible scenarios of oligometastatic disease, including preferred sites of occurrence and chronological progression. Due to the novelty of this theme and the heterogeneity of the disease, uncertainties still exist, and the ability to provide confident guidelines is challenging. Currently, there are no effective predictors to determine the response and provide clear indications for surgical interventions and systemic treatments in oligometastatic disease. Treatment decisions are commonly based on apparent disease control by systemic therapies, with a short observation period and imaging assessments. Nonetheless, the inherent risk of misinterpretation remains a constant concern. The emergence of novel technologies and therapeutic modalities, such as immunotherapy, cellular therapy, and adoptive therapies, holds the potential to reshape the landscape of surgical treatment for the oligometastatic disease in gastric cancer, expanding the surgeon's role in this multidisciplinary approach. Prospective tools for patient selection in oligometastatic gastric cancer are being explored. Using non-invasive, cost-effective, widely available imaging techniques that provide real-time information may revolutionize medical practice, ensuring precision medicine accessibility, even in resource-constrained small healthcare facilities. Incorporating molecular classifications, liquid biopsies, and radiomic analysis in a complementary protocol will augment patient selection precision for surgical intervention in oligometastasis. Hopefully, these advancements will render surgeries unnecessary in many cases by providing highly effective alternative treatments.

Acute cholecystitis (AC) is an acute inflammatory process of the gallbladder that may be associated with potentially severe complications, such as empyema, gangrene, perforation of the gallbladder, and sepsis. The gold standard treatment for AC is laparoscopic cholecystectomy. However, for a small group of AC patients, the risk of laparoscopic cholecystectomy can be very high, mainly in the elderly with associated severe diseases. In these critically ill patients, percutaneous cholecystostomy or endoscopic ultrasound gallbladder drainage may be a temporary therapeutic option, a bridge to cholecystectomy. The objective of this Brazilian College of Digestive Surgery Position Paper is to present new advances in AC treatment in high-risk surgical patients to help surgeons, endoscopists, and physicians select the best treatment for their patients. The effectiveness, safety, advantages, disadvantages, and outcomes of each procedure are discussed. The main conclusions are: a) AC patients with elevated surgical risk must be preferably treated in tertiary hospitals where surgical, radiological, and endoscopic expertise and resources are available; b) The optimal treatment modality for high-surgical-risk patients should be individualized based on clinical conditions and available expertise; c) Laparoscopic cholecystectomy remains an excellent option of treatment, mainly in hospitals in which percutaneous or endoscopic gallbladder drainage is not available; d) Percutaneous cholecystostomy and endoscopic gallbladder drainage should be performed only in well-equipped hospitals with experienced interventional radiologist and/or endoscopist; e) Cholecystostomy catheter should be removed after resolution of AC. However, in patients who have no clinical condition to undergo cholecystectomy, the catheter may be maintained for a prolonged period or even definitively; f) If the cholecystostomy catheter is maintained for a long period of time several complications may occur, such as bleeding, bile leakage, obstruction, pain at the insertion site, accidental removal of the catheter, and recurrent AC; g) The ideal waiting time between cholecystostomy and cholecystectomy has not yet been established and ranges from immediately after clinical improvement to months. h) Long waiting periods between cholecystostomy and cholecystectomy may be associated with new episodes of acute cholecystitis, multiple hospital readmissions, and increased costs. Finally, when selecting the best treatment option other aspects should also be considered, such as costs, procedures available at the medical center, and the patient's desire. The patient and his family should be fully informed about all treatment options, so they can help making the final decision.

BACKGROUND: After validation in multiple types of liver disease patients, the MELD score was adopted as a standard by which liver transplant candidates with end-stage liver disease were prioritized for organ allocation in the United States since 2002, and in Brazil, since 2006. AIMS: To analyze the mortality profile of patients on the liver transplant waiting list correlated to MELD score at the moment of transplantation. METHODS: This study used the data from the Secretary of Health of the São Paulo State, Brazil, which listed 22,522 patients, from 2006 (when MELD score was introduced in Brazil) until June 2009. Patients with acute hepatic failure and tumors were included as well. We also considered the mortality of both non-transplanted and transplanted patients as a function of the MELD score at presentation. RESULTS: Our model showed that the best MELD score for patients on the liver transplant waiting list associated to better results after liver transplantation was 26. CONCLUSIONS: We found that the best score for applying to liver transplant waiting list in the State of São Paulo was 26. This is the score that minimizes the mortality in both non-transplanted and liver transplanted patients.

BACKGROUND: Hepatosplenic schistosomiasis is an endemic disease prevalent in tropical countries and is associated with a high incidence of portal vein thrombosis. Inflammatory changes caused by both parasitic infection and portal thrombosis can lead to the development of chronic liver disease with potential carcinogenesis. AIMS: To assess the incidence of portal vein thrombosis and hepatocellular carcinoma in patients with schistosomiasis during long-term follow-up. METHODS: A retrospective study was conducted involving patients with schistosomiasis followed up at our institution between 1990 and 2021. RESULTS: A total of 126 patients with schistosomiasis were evaluated in the study. The mean follow-up time was 16 years (range 5-31). Of the total, 73 (57.9%) patients presented portal vein thrombosis during follow-up. Six (8.1%) of them were diagnosed with hepatocellular carcinoma, all with portal vein thrombosis diagnosed more than ten years before. CONCLUSIONS: The incidence of hepatocellular carcinoma in patients with schistosomiasis and chronic portal vein thrombosis highlights the importance of a systematic long-term follow-up in this group of patients.

This Brazilian multi-society position statement on emerging bariatric and metabolic surgical procedures was issued by the Brazilian Society of Bariatric and Metabolic Surgery (SBCBM), the Brazilian College of Digestive Surgery (CBCD), and the Brazilian College of Surgeons (CBC). This document is the result of a Brazilian Emerging Surgeries Forum aimed at evaluating the results of surgeries that are not yet listed in the Federal Council of Medicine (CFM), the regulatory agency that oversees and regulates medical practice in Brazil. The Forum integrated more than 400 specialists and academics with extensive knowledge about bariatric and metabolic surgery, representing the three surgical societies: SBCBM, CBC, and CBCD. International speakers participated online and presented their experiences with the techniques under discussion, emphasizing the regulatory policies in their countries. The indications for surgery and the subsequent procedures were carefully reviewed, including one anastomosis gastric bypass (OAGB), single anastomosis duodeno-ileal with sleeve gastrectomy (SADI-S or OADS), sleeve gastrectomy with transit bipartition (SGTB), and sleeve gastrectomy with ileal interposition (SGII). The recommendations of this document are based on an extensive literature review and discussions among bariatric surgery specialists from the three surgical societies. We concluded that patients with a body mass index over 30 kg/m2 may be candidates for metabolic surgery in the presence of comorbidities (arterial hypertension and type 2 diabetes) with no response to clinical treatment of obesity or in the control of other associated diseases. Regarding the surgical procedures, we concluded that OAGB, OADS, and SGTB are associated with low morbidity rates, satisfactory weight loss, and resolution of obesity-related comorbidities such as diabetes and arterial hypertension. SGII was considered a good and viable promising surgical alternative technique. The recommendations of this statement aim to synchronize our societies with the sentiments and understandings of most of our members and also serve as a guide for future decisions regarding bariatric surgical procedures in our country and worldwide.

BACKGROUND: Lipomatous pseudohypertrophy of the pancreas, pancreatic lipomatosis, pancreatic steatosis, non-alcoholic fatty pancreatic disease, or fatty pancreas is an extremely rare disease, characterized by the organ enlargement and a localized or diffuse replacement of pancreatic acinar cells by mature adipose tissue, preserving the pancreatic ductal system and islets of Langerhans. AIMS: To report a rare case of lipomatous pseudohypertrophy of the pancreas in a symptomatic patient and the surgical treatment employed. METHODS: A 24-year-old male patient with weight loss (10 kilograms in 8 months), hyperglycemia, severe and recurrent acute abdominal pain, epigastric discomfort associated with nausea, vomiting, and jaundice for 40 days. Magnetic resonance imaging was performed, revealing an irregular lipomatous pseudohypertrophy of the pancreas, measuring 6.0 × 5.6 cm in the head, uncinate process, and part of the body of the pancreas. The pancreatic duct dilation was diffuse and irregular, associated with atrophy of the remnant parenchyma, particularly in the tail of the pancreas. The patient underwent pancreatoduodenectomy without total mesopancreas excision followed by pancreatojejunostomy. RESULTS: The postoperative course was uneventful, the length of stay in the ICU was two days, and the patient was discharged on the seventh postoperative day. CONCLUSIONS: The disease treatment depends on the signs and symptoms at presentation and a pancreatoduodenectomy is indicated in patients with severe and recurrent abdominal pain.

BACKGROUND: Weight regain in the postoperative period after bariatric surgery is directly related to the relapse of preoperative comorbidities and a negative impact on the patients' biochemical profile. AIMS: To assess the metabolic impact of weight regain on preoperative comorbidities and on patients' biochemical profiles, in order to show the impact of the complications on the metabolic outcomes of bariatric surgery. METHODS: A retrospective study was carried out with 75 women in the late postoperative period of bariatric surgery who presented pathological weight regain (≥20% of the maximum weight loss). Data of interest consisted of glycemic, lipid, and inflammatory profile measurements at three different moments of evaluation: preoperative period, at the weight nadir (minimum weight), and after weight regain. A multivariate analysis was performed. RESULTS: The mean age was 46.39±12.09 years. Preoperative body mass index was 40.10±4.11 kg/m2. There was an overall increase of 3.36 points in the mean body mass index between the nadir and after regain: from 26.30±3.9 kg/m2 to 29.66±4.66 kg/m2. The mean time to reach the nadir was 18±7.6 months, with an average percentage of excess weight loss of 91.08±11.8%. The median time for pathological weight regain was 48 months, and the mean regain amongst the sample was 8.85±5.65 kg. There was a significant correlation between pathological weight regain and levels of insulin (r=0.351; p<0.011), C-peptide (r=0.303; p<0.011), C-reactive protein (r=0.402; p<0.001), and vitamin D (r=-0.435; p<0.001), the last two being the most influenced by the percentage of weight regained. CONCLUSIONS: The pathological weight regain in the postoperative period of bariatric surgery results in losses in the patients' metabolic and inflammatory profiles. However, the biochemical benefits are sustained up to the preoperative levels of the parameters analyzed.
