BACKGROUND: Obesity is a multifactorial disease affecting a significant portion of the population. Bariatric surgery emerges as a prominent approach in this context, representing an effective treatment both in the short and long term. The costs associated with bariatric surgery vary depending on the characteristics of the patients, current hospital practices, and available funding sources. AIMS: To analyze the costs of minimally invasive bariatric surgery for the treatment of obesity in a tertiary federal public hospital. METHODS: An observational and descriptive study aimed at assessing the costs associated with laparoscopic vertical gastrectomy (GV) and Roux-en-Y gastric bypass (RYGB) in a federal public tertiary service from 2018 to 2021. Data were obtained through the management of medical-hospital expenses related to surgical and anesthetic supplies, as well as the amount reimbursed by the funding source to the hospital. RESULTS: Over the analyzed period, a total of 177 minimally invasive bariatric surgeries were performed. In terms of the charges, since 2018, the hospital has been receiving an amount of R$ 6,145.00 for the "bariatric surgery by videolaparoscopy" procedure, which includes RYGB, and R$ 4,095.00 for "vertical gastrectomy." Regarding the average hospital cost of surgical supplies, RYGB incurred a total of R$ 9,907.54, while GV incurred a total of R$ 9,315.84. The average total cost of RYGB was R$ 10,799.23, and, for GV, it was R$ 10,207.53. These figures indicate that the hospital incurred a loss of approximately R$ 4,654.23 for performing RYGB and R$ 6,112.53 for GV. CONCLUSION: Despite the increasing number of eligible patients for surgical treatment of obesity and the consequent quantitative growth of these procedures funded by the Brazilian Unified Health System (SUS), the costs exceed the reimbursement from the funding source in federal public hospitals. There is a need for a precise assessment of financing in the fight against obesity.

BACKGROUND: Colon cancer is the third most common malignancy in Colombia, only exceeded by prostate and breast cancers. It is the second most common cancer among females and the third most common among males. The epidemiology of this disease has changed in Colombia, and its peak incidence has now surpassed that of gastric cancer. AIMS: We aimed to determine the association between hospital surgical volume and mortality in patients with colon cancer undergoing surgical resection in Colombia. METHODS: This was a national retrospective cohort study based on administrative data and included adult patients undergoing surgical resection for colon cancer who were enrolled in Colombia's contributory health system between 2012 and 2017. We defined exposure as the hospital's surgical volume where the colon cancer surgery was performed. We classified the patients as exposed to a high surgical volume (above the 90th percentile of the provider distribution) and a low surgical volume (under the 90th percentile). The main outcomes were 30-day and 1-year mortality. Multivariate Poisson regressions were used to identify the association between exposure and mortality rates. RESULTS: The study included 4,647 patients, of which 4,188 underwent surgery at hospitals with a colectomy volume lower than 33 per year and 459 underwent surgery at institutions with volumes equal to or higher than 33 per year. In the multivariate analysis, after adjusting for observable variables, a lower risk of 30-day mortality was found in patients who underwent surgery at high surgical volume institutions (relative risk - RR 0.57, 95% confidence interval - 95%CI 0.033-0.97). No differences were found in the one-year mortality. CONCLUSION: The high surgical volume of a hospital is associated with a 30-day mortality in colon cancer, as described in other studies, but the 1-year mortality did not show this association. Prospective studies are required to establish a causal relationship.

BACKGROUND: Pancreas divisum is an anatomical abnormality where the junction of the main and accessory pancreatic duct fails to occur and the smaller-caliber duct acts as dominant, resulting in overload during the drainage of the organ's secretion through the minor duodenal papilla. AIMS: To report a case of recurrent acute pancreatitis due to symptomatic pancreas divisum who underwent pancreatoduodenectomy. CASE REPORT: A 21-year-old male patient presented with intermittent painful crises, located in the upper abdomen, with radiation to the back, associated with nausea and vomiting, for the past three years. Magnetic resonance imaging and endoscopic retrograde cholangiopancreatography revealed pancreas divisum, subsequently confirmed by endoscopic ultrasound. An attempt was made through endoscopic intervention but failed to catheterize the minor papilla; therefore, a pancreaticoduodenectomy was indicated. The organ was identified as hard and atrophied, with moderate peripancreatic inflammation. The histopathological findings also identified a focal well-differentiated G1-type neuroendocrine tumor measuring 0.4 cm. CONCLUSIONS: In patients with pancreas divisum, rare cases may progress to recurrent acute pancreatitis. Pancreaticoduodenectomy is an option in symptomatic patients who had no success with endoscopic treatment.

BACKGROUND: Identification of epidemiological risk factors in Barrett esophagus resulting in dysplasia and adenocarcinoma and its impact on prevention and early detection. AIMS: To evaluate epidemiological risk factors involved in the development of dysplasia and esophageal adenocarcinoma from Barrett esophagus in a specific population. To critically analyze the surveillance period, aiming to individualize follow-up time according to identified risks. METHODS: A retrospective case-control study was carried out at a tertiary center involving patients diagnosed and followed up for Barrett esophagus. Patients who developed esophageal adenocarcinoma and/or dysplasia were compared to those who did not, considering variables such as gender, age, smoking status, body mass index, ethnicity, and Barrett esophagus extension. Logistic regression was performed to measure the odds ratio for risk factors associated with the outcome of adenocarcinoma and dysplasia. The presence of epidemiological risk factors in this population was correlated with the time taken to develop esophageal adenocarcinoma from metaplasia. RESULTS: A statistically significant difference was observed in smoking status, race, gender, Barrett esophagus extension, and age between the group with esophageal adenocarcinoma and the group without it. Smokers and former smokers had a 4.309 times higher risk of developing esophageal adenocarcinoma, and each additional centimeter of Barrett esophagus increased the risk by 1.193 times. In the dysplasia group, smoking status, Barrett esophagus extension, and age were statistically significant factors; each additional centimeter of Barrett esophagus extension increased the risk of dysplasia by 1.128 times, and each additional year of age increased the risk by 1.023 times. Patients without risk factors did not develop esophageal adenocarcinoma within 12 months, even with prior dysplasia. CONCLUSIONS: The study confirmed a higher risk of developing dysplasia and esophageal adenocarcinoma in specific epidemiological groups, allowing for more cost-effective monitorization for patients with Barrett esophagus.

BACKGROUND: Anal cancer is a relatively rare disease, and there is a lack of survival data from low- and middle-income countries. AIMS: The aim of this study was to investigate the survival rates and prognostic factors of anal cancer cases treated at a High-Complexity Oncology Care Center in Rio de Janeiro, Brazil. METHODS: A retrospective cohort study was conducted involving 665 cases of squamous cell carcinoma of the anus/anal canal treated from 2000 to 2016. To estimate the 5-year overall survival probability and survival according to selected variables, the Kaplan-Meier method and the log-rank test were applied. To identify factors associated with survival, the Cox proportional hazards model, stratified by staging, was used to estimate hazard ratios (HR). Ninety-five percent confidence intervals (95%CI) were also calculated. RESULTS: The overall survival probability was 62.20% (95%CI 57.90-66.20). Higher survival rates were observed in female cases, those with non-advanced staging, and those treated with chemoradiotherapy (p<0.001). Among cases with advanced staging, being female was a protective factor against death (HR=0.52; 95%CI 0.28-0.93). Compared to chemoradiotherapy, at least one type of treatment was identified as a risk factor: chemoradiotherapy + surgery among cases with non-advanced staging (HR=22.65; 95%CI 5.65-90.81), radiotherapy among cases with advanced staging (HR=2.71; 95%CI 1.39-5.30), and among cases with unknown staging, no treatment (HR=3.36; 95%CI 1.73-6.50), radiotherapy (HR=2.38; 95%CI 1.46-3.88), and radiotherapy + surgery (HR=3.99; 95%CI 1.20-13.27). CONCLUSIONS: The findings support the superiority of chemoradiotherapy over other therapeutic modalities for anal cancer, resulting in increased survival and a better prognosis.

BACKGROUND: Surgery after neoadjuvant chemotherapy (CT) improves the prognosis of colorectal liver metastases (CRLM). AIMS: The aim of this study was to evaluate the predictive factors of the histological response of CRLM after neoadjuvant treatment. METHODS: A retrospective monocentric study including patients with CRLM operated after neoadjuvant treatment. Assessment of histological response was based on the Rubbia-Brandt tumor regression grading score. The scores were grouped into two types of response: Response Group (R) and No Response Group (NR). RESULTS: The study included 77 patients (mean age=56 years, sex ratio=1.57). Node metastases were noticed in 62% of cases. Synchronous liver metastasis was present in 42 cases (55%) and metachronous liver metastasis in 45%. Neoadjuvant treatment consisted of CT only in 52 patients (68%) and CT with targeted therapy in 25 patients (32%). Chemo-induced lesions were present in 44 patients (57%). Histological response was presented (Group R) in 36 cases (47%) and absent (Group NR) in 41 cases (53%). The overall survival of our patients was 32 months. For Group R, survival was significantly greater (p=0.001). The predictive factors of histological response identified were delay in the onset of liver metastasis greater than 14 months (p=0.027) and neoadjuvant treatment combining CT and targeted therapy (p=0.031). In multivariate analysis, the type of neoadjuvant treatment (p=0.035) was an independent predictive factor of histological response. CONCLUSIONS: Predictive factors of histological response would allow us to identify patients who would benefit most from neoadjuvant treatment. These patients with CRLM onset of more than 14 months and treated with CT combined with targeted therapy would be the best candidates for a neoadjuvant CT strategy followed by surgical resection.

BACKGROUND: Chile presents one of the lowest organ donation rates, resulting in pediatric liver waitlist mortality rates up to 38.1%. Live donor liver transplantation is one of the main alternatives to decrease waitlist mortality, mostly utilized in our country for small children up to 20 kg. AIMS: The aim of this study was to report a three-case series of adult-to-pediatric living donor liver transplantation using a full left lobe graft. METHODS: We report three cases of children with more than 20 kg who received complete left hemi-grafts in different clinical scenarios. The indications and techniques adopted are discussed. RESULTS: Three children, two girls and one boy, aged 11, 7, and 3 years, were transplanted. The indications for transplant were fulminant hepatitis of autoimmune etiology, hepatoblastoma, and chronic liver failure due to autoimmune hepatitis, respectively. The evolution was satisfactory in all three children, and to date, all are well, approximately 12-24 months after the transplant. CONCLUSIONS: The use of a living donor left lateral segment (segments 2 and 3) has been successfully employed in pediatric liver transplantation. However, it is only suitable for infants and low-weight children. This approach using the whole left hemi-liver graft contributes to the reduction of small-for-size syndrome, mortality rate, and waiting times associated with deceased donors.

BACKGROUND: According to the literature, some factors are associated with the development of postoperative complications including surgical approach, smoking, comorbidities, nutritional status, classification of the American Society of Anesthesiologists (ASA), fasting time period, and others. In the case of surgical patients, some factors are important for the assessment of the outcomes. AIMS: To investigate the factors associated with the likelihood of postoperative complications in surgical patients. METHODS: A prospective observational study was conducted with patients who were admitted to hospital more than 24 h. The following variables were investigated: nutritional risk screening, body mass index, ASA classification, fasting time, length of hospital stay, and postoperative complications. For statistical analysis, the Chi-square, Fisher's exact, and Mann-Whitney tests were used. To investigate the risk factors associated with postoperative complications, simple and multiple Cox regression analyses were used. RESULTS: In the total group of patients, there was an association between postoperative complications and men (p=0.0197), surgical risk (ASA) (p=0.0397) and length of hospital stay (p<0001); men showed a risk 2.2 times greater than women for some kind of postoperative complication (p=0.0456; PR=2.167; 95%CI 1.015-4.624). In patients undergoing gastrointestinal surgery, there was an association between postoperative complications and length of hospital stay (p<0001). In patients undergoing other surgeries, there was an association between postoperative complications and length of hospital stay (p<0001) and ASA classification (p=0.0160); ASA classification was considered a factor associated with the probability of postoperative complications (p=0.0335; PR=4.125; 95%CI 1.117-15.237). CONCLUSIONS: Men in the total group of patients and the ASA 3 or 4 criteria in the group of patients undergoing other surgeries were considered factors associated with the occurrence of complications in the postoperative period.

BACKGROUND: The incidence of biliary duct injuries remains higher in laparoscopic cholecystectomy (LC) in comparison to open surgery. The Critical View of Safety (CVS) was introduced by Strasberg as a strategy for reducing this catastrophic complication. AIM: The aim of this study was to evaluate how often an adequate CVS is achieved during LC, the determining factors for its success, and the associated surgical outcomes. METHODS: This is a prospective study. CVS photographs of all patients who underwent LC by the same surgeon between 2020 and 2023 were taken. Success in achieving CVS was analyzed by the surgeon herself and posteriorly by hepatobiliary specialists. Patients were classified into two groups: CVS achieved and CVS not achieved. Finally, multivariable logistic regression was used to examine the association between preoperatory factors and surgical complications. RESULTS: Three hundred and nine consecutive patients were submitted to LC. There were 73.5% elective CL and 26.5% acute cholecystitis. The age ranged from 14 to 87 years, and 76.8% were female. The median body mass index was 26.7. Previous abdominal surgeries were present in 64%, and 26% were obese. The CVS was achieved in 79.9% of the patients, and there were no surgical complications in this group. The factors associated with nonachievement were acute cholecystitis (p=0.007), male sex (p=0.014), and previous surgeries (p=0.021). Three patients needed a subtotal cholecystectomy due to severe inflammation. There was no statistical correlation between the identification of CVS and surgical complications. CONCLUSIONS: The CVS is achieved in most patients. Acute cholecystitis, male sex, and previous abdominal operations are associated with difficulties in obtaining CVS.

BACKGROUND: Lymph node status is vital for gastric cancer (GC) prognosis, but the conventional pN stage may be limited by variations in lymphadenectomy and stage migration. The N-Ratio, which assesses the ratio of metastatic to resected lymph nodes, emerges as a promising prognostic tool. AIMS: To assess N-Ratios prognostic value in GC, particularly in patients with <25 resected lymph nodes. METHODS: Patients who underwent gastrectomy with curative intent for GC were retrospectively evaluated. The N-Ratio categories were determined using the ROC curve method, and the area under the curve (AUC) was used as a measure of performance in predicting recurrence/death. RESULTS: A total of 561 GC patients were included in the study, 57% had pN+ status, and 17.5% had <25 resected lymph nodes. N-Ratio, with a mean of 0.12, predicted survival with 74% accuracy (AUC=0.74; 95%CI 0.70-0.78, p<0.001). N-Ratio categories included: N-Ratio 0 (43%); N-Ratio 1 (12.3%); N-Ratio 2 (31.6%); and N-Ratio 3 (13.2%). Disease-free survival (DFS) varied among all N-Ratio groups, with N-Ratio 3 showing worse survival than pN3 cases (DFS=21.8 vs. 11 months, p=0.022, p<0.05). In cases with <25 resected lymph nodes, DFS was not significantly worse in N-Ratio 0 (68.8 vs. 81.9%, p=0.061, p>0.05) and N-Ratio 1 (66.2 vs. 50%, p=0.504, p>0.05) groups. The DFS of N-Ratio-0 cases with <25 lymph nodes was similar to N-Ratio 1 cases. CONCLUSIONS: N-Ratio influenced survival in GC patients, especially in advanced lymph node disease (N-Ratio 3). Considering that N-Ratio does not impact pN0 cases, individualized prognosis assessment is essential for patients with <25 resected lymph nodes.

BACKGROUND: Incisional hernia (IH) is an abdominal wall defect due to a previous laparotomy, and surgical repair is the only treatment. IH has a negative impact on patients' quality of life. In the last decades, the approach has improved from open to laparoscopic and robotic surgery with the objective of promoting better abdominal wall function after reconstruction. Today, robotic enhanced-view totally extraperitoneal (reTEP) is one of the most advanced techniques for abdominal wall reconstruction. AIMS: The aim of this study was to analyze the early results of patients with incisional hernia submitted to repair with reTEP. METHODS: This is a retrospective cohort study, and all patients who underwent reTEP surgery for ventral hernia in the years 2021 and 2022 were included. The only exclusion criteria were patients who underwent another type of herniorrhaphy. Statistical analysis was performed using the Stata software. RESULTS: A total of 32 participants were submitted to reTEP; the majority had an incisional hernia, and according to the European Hernia Society, EUS-M score 3 was the most prevalent. The mean surgical time was 170 min, and the console time was 142 min. Most patients stayed 2 days in the hospital. No intraoperative complications were reported. CONCLUSIONS: reTEP is a safe and effective technique and has favorable outcomes in the early postoperative period. Further studies with larger sample sizes and longer follow-up periods are needed to confirm these findings.

BACKGROUND: The unresectable pancreatic head tumors develop obstructive jaundice and cholestasis during follow-up. Cholestasis is associated with complications and treatment options are endoscopic stenting (ES) and biliary bypass surgery (BBS). AIMS: The aim of the current study was to compare the safety and efficacy of biliary bypass surgery (BBS) and endoscopic stenting (ES) for cholestasis in advanced pancreas cancer. METHODS: This is a retrospective cohort of patients with cholestasis and unresectable or metastatic pancreas cancer, treated with BBS or ES. Short and long-term outcomes were evaluated. We considered the need for hospital readmission due to biliary complications as treatment failure. RESULTS: A total of 93 patients (BBS=43; ES=50) were included in the study. BBS was associated with a higher demand for postoperative intensive care (37 vs.10%; p=0.002, p<0.050), longer intensive care unit stay (1.44 standard deviation±2.47 vs. 0.66±2.24 days; p=0.004, p<0.050), and longer length of hospital stay (7.95±2.99 vs. 4.29±5.50 days; p<0.001, p<0.050). BBS had a higher risk for procedure-related complications (23 vs. 8%; p=0.049, p<0.050). There was no difference in overall survival between BBS and ES (p=0.089, p>0.050). ES was independently associated with a higher risk for treatment failure than BBS on multivariate analysis (hazard ratio 3.97; p=0.009, p<0.050). CONCLUSIONS: BBS is associated with longer efficacy than ES for treating cholestasis in advanced pancreatic cancer. However, the BBS is associated with prolonged intensive care unit and hospital stays and higher demand for intensive care.

Insulinomas are rare neoplasms of the endocrine pancreas. Minimally invasive treatment options for insulinomas have gained prominence, replacing surgical resection due to its associated morbidity and mortality. Radiofrequency ablation (RFA) has emerged as a relevant treatment option. We present a case of a female patient with neuroglycopenic symptoms and severe hypoglycemic crises. The abdominal magnetic resonance imaging (MRI) showed a small nodular lesion in the pancreatic body. Laparotomy was performed, followed by RFA using a 15-mm active-tipped needle. No complications transpired, and no hypoglycemic episodes were observed during 12 months of follow-up.

BACKGROUND: Mechanic sutures represent an enormous benefit for digestive surgery in decreasing postoperative complications. Currently, the advantages of motorized stapler are under evaluation. AIMS: To compare the efficacy of mechanic versus motorized stapler in gastric surgery, analyzing rate of leaks, bleeding, time of stapling, and postoperative complications. METHODS: Ninety-eight patients were submitted to gastric surgery, divided into three groups: laparoscopic sleeve gastrectomy (LSG) (n=47), Roux-en-Y gastric bypass (LRYGB) (n=30), and laparoscopic distal gastrectomy (LDG) (n=21). Motorized staplers were employed in 61 patients. The number of firings, number of clips, time of total firings, total time to complete the surgery, and postoperative outcome were recorded in a specific protocol. RESULTS: Patients submitted to LSG, LRYGB, and LDG recorded a shorter time to complete the procedure and a smaller number of firings were observed using motorized stapler (p<0.0001). No differences were identified regarding the number of clips used in patients submitted to LSG. In the group that used mechanic stapler to complete gastrojejunostomy, jejuno-jejuno-anastomosis, and jejunal transection, it was observed more prolonged time of firing and total time for finishing the procedure (p=0.0001). No intraoperative complications were found comparing the two devices used. Very similar findings were noted in the group of patients undergoing LDG. CONCLUSIONS: The motorized stapler offers safety and efficacy as demonstrated in prior reports and is relevant since less total time of surgical procedure without intraoperative or postoperative complications were confirmed.

BACKGROUND: One anastomosis gastric bypass (OAGB) has gained prominence in the search for better results in bariatric surgery. However, its efficacy and safety compared to Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) remain ill-defined. AIMS: To compare the efficacy and safety of OAGB relative to RYGB and SG in the treatment of obesity. METHODS: We systematically searched PubMed, EMBASE, Cochrane Library, Lilacs, and Google Scholar databases for randomized controlled trials comparing OAGB with RYGB or SG in the surgical approach to obesity. We pooled outcomes for body mass index, percentage of excess weight loss, type-2 diabetes mellitus remission, complications, and gastroesophageal reflux disease. Statistical analyses were performed with R software (version 4.2.3). RESULTS: Data on 854 patients were extracted from 11 randomized controlled trials, of which 422 (49.4%) were submitted to OAGB with mean follow-up ranging from six months to five years. The meta-analysis revealed a significantly higher percentage of excess weight loss at 1-year follow-up and a significantly lower body mass index at 5-year follow-up in OAGB patients. Conversely, rates of type-2 diabetes mellitus remission, complications, and gastroesophageal reflux disease were not significantly different between groups. The overall quality of evidence was considered very low. CONCLUSIONS: Our results corroborate the comparable efficacy of OAGB in relation to RYGB and SG in the treatment of obesity, maintaining no significant differences in type-2 diabetes mellitus remission, complications, and gastroesophageal reflux disease rates.

BACKGROUND: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease in the world and was recently renamed to emphasize its metabolic component. AIMS: This article seeks to fill the gap in specific guidelines for patients with obesity and MASLD who will undergo bariatric surgery. METHODS: A systematic search for guidelines was carried out on PubMed and Embase platforms. RESULTS: A total of 544 articles were found, of which 11 were selected according to inclusion and exclusion criteria. All 11 guidelines are from clinical societies; therefore, they do not include some necessary interpretations for bariatric patients. CONCLUSIONS: We recommend that every patient undergoing bariatric and metabolic surgery be screened initially with the Fibrosis-4 (FIB-4) score, followed by transient hepatic elastography (vibration-controlled transient elastography, VCTE), especially for those with FIB-4>1.3. However, interpreting VCTE results in obese patients requires further studies to define the actual cutoff values. Enhanced Liver Fibrosis® shows promise but its availability is limited. The indication for liver biopsy during surgery needs to be individualized but it is recommended for those with changes in FIB-4 and/or VCTE. Family screening is recommended for relatives of young patients with already advanced fibrosis. Liver transplantation is an option for patients with advanced MASLD but the optimal timing for bariatric surgery with transplantation is still unclear. Regular follow-up and VCTE examination are recommended to monitor disease progression after surgery.

Postoperative infectious complications are extremely important to surgeons and the entire medical care team. Among these complications, surgical site infection (SSI) appears to be one of the earliest and most prevalent events and is considered an inherent complication of surgical procedures. In oncological patients submitted to resections of digestive system tumors, there is a confluence of several risk factors for SSI, making it necessary to establish measures to maximize the control of this condition to provide a better prognosis for these patients. Some risk factors for SSI are the manipulation of structures hosting the highest density of pathogenic microorganisms, such as the colon, the patient's performance status, the patient's nutritional status, the use of chemotherapy and/or radiotherapy, and the surgical procedure itself, which tends to last longer and be more complex than surgeries for benign conditions of the digestive system. Therefore, this review sought to provide a qualitative analysis and a summary of the literature regarding the SSI of postoperative tumor patients who underwent surgical resection and were well-structured postoperatively, to provide objective data on this problem, and alert about the well-structured needs of individualized pre-, peri-, and post-protocols to avoid the development of these events.

BACKGROUND: The recommended treatment for cholecystocholedocholithiasis is cholecystectomy (CCT) associated with endoscopic retrograde cholangiopancreatography (ERCP). CCT with intraoperative ERCP is associated with higher success rates and lower hospital stays and hospital costs. However, some case series do not describe the exact methodology used: whether ERCP or CCT was performed first. AIMS: Verify if there is a difference, in terms of outcomes and complications, when intraoperative ERCP is performed immediately before or after CCT. METHODS: This is a retrospective case-control study analyzing all patients who underwent CCT with intraoperative ERCP between January 2021 and June 2022, in a tertiary hospital in southern Brazil, for the treatment of cholecystocholedocholithiasis. RESULTS: Out of 37 patients analyzed, 16 (43.2%) underwent ERCP first, immediately followed by CCT. The overall success rate for the cannulation of the bile duct was 91.9%, and bile duct clearance was achieved in 75.7% of cases. The post-ERCP pancreatitis rate was 10.8%. When comparing the "ERCP First" and "CCT First" groups, there was no difference in technical difficulty for performing CCT. The "CCT First" group had a higher rate of success in bile duct cannulation (p=0.020, p<0.05). Younger ages, presence of stones in the distal common bile duct and shorter duration of the procedure were factors statistically associated with the success of the bile duct clearance. Lymphopenia and cholecystitis as an initial presentation, in turn, were associated with failure to clear the bile duct. CONCLUSIONS: There was no significant difference in terms of complications and success in clearing the bile ducts among patients undergoing CCT and ERCP in the same surgical/anesthetic procedure, regardless of which procedure was performed first. Lymphopenia and cholecystitis have been associated with failure to clear the bile duct.
