BACKGROUND: Bile duct injury (BDI) causes significant sequelae for the patient in terms of morbidity, mortality, and long-term quality of life, and should be managed in centers with expertise. Anatomical variants may contribute to a higher risk of BDI during cholecystectomy. AIMS: To report a case of bile duct injury in a patient with situs inversus totalis. METHODS: A 42-year-old female patient with a previous history of situs inversus totalis and a BDI was initially operated on simultaneously to the lesion ten years ago by a non-specialized surgeon. She was referred to a specialized center due to recurrent episodes of cholangitis and a cholestatic laboratory pattern. Cholangioresonance revealed a severe anastomotic stricture. Due to her young age and recurrent cholangitis, she was submitted to a redo hepaticojejunostomy with the Hepp-Couinaud technique. To the best of our knowledge, this is the first report of BDI repair in a patient with situs inversus totalis. RESULTS: The previous hepaticojejunostomy was undone and remade with the Hepp-Couinaud technique high in the hilar plate with a wide opening in the hepatic confluence of the bile ducts towards the left hepatic duct. The previous Roux limb was maintained. Postoperative recovery was uneventful, the drain was removed on the seventh post-operative day, and the patient is now asymptomatic, with normal bilirubin and canalicular enzymes, and no further episodes of cholestasis or cholangitis. CONCLUSIONS: Anatomical variants may increase the difficulty of both cholecystectomy and BDI repair. BDI repair should be performed in a specialized center by formal hepato-pancreato-biliary surgeons to assure a safe perioperative management and a good long-term outcome.

BACKGROUND: There is a lack of valid and specific tools to measure chronic constipation severity in Brazil. AIMS: To validate the Constipation Scoring System for Brazilian spoken Portuguese. METHODS: Translation, cultural adaptation, and validation itself (reliability and convergent and divergent validation). Translation: definitive version from the original version's translation and evaluation by specialists. Cultural adaptation: score content analysis of the definitive version, as an interview to patients. Interobserver reliability: application by two researchers on the same day. Intraobserver reliability: same researcher at different times, in a 7-day interval. Divergent validation: non-constipated volunteers. Convergent validation: two groups, good response to clinical treatment and refractory to treatment. RESULTS: Cultural adaptation: 81 patients, 89% female, with mean age of 55 and seven years of schooling, and overall content validity index was 96.5%. Inter and intraobserver reliability analysis: 60 patients, 86.7% female, mean age of 56 and six years of schooling, and the respective intraclass correlation coefficients were 0.991 and 0.987, p<0.001. Divergent validation: 40 volunteers, 25 male, mean age of 49 years, and the mean global score was 2. Convergent validation of patients with good response to clinical treatment: 47 patients, 39 female, mean age of 60 and six years of schooling, and the pre- and post-treatment scores were 19 and 8, respectively (p<0.001). Convergent validation of refractory to clinical treatment patients: 75 patients, 70 female, mean age of 53 and seven years of schooling, and the global average score was 22. CONCLUSIONS: The Constipation Scoring System (Índice de Gravidade da Constipação Intestinal) validated for the Brazilian population is a reliable instrument for measuring the severity of intestinal chronic constipation.

BACKGROUND: Magnetic ring (MSA) implantation in the esophagus is an alternative surgical procedure to fundoplication for the treatment of gastroesophageal reflux disease. AIMS: The aim of this study was to analyse the effectiveness and safety of magnetic sphincter augmentation (MSA) in patients with gastroesophageal reflux disease (GERD). METHODS: A systematic literature review of articles on MSA was performed using the Medical Literature Analysis and Retrieval System Online (Medline) database between 2008 and 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies. RESULTS: A total of 22 studies comprising 4,663 patients with MSA were analysed. Mean follow-up was 27.3 (7-108) months. The weighted pooled proportion of symptom improvement and patient satisfaction were 93% (95%CI 83-98%) and 85% (95%CI 78-90%), respectively. The mean DeMeester score (pre-MSA: 34.6 vs. post-MSA: 8.9, p=0.03) and GERD-HRQL score (pre-MSA: 25.8 vs. post-MSA: 4.4, p<0.0001) improved significantly after MSA. The proportion of patients taking proton pump inhibitor (PPIs) decreased from 92.8 to 12.4% (p<0.0001). The weighted pooled proportions of dysphagia, endoscopic dilatation and gas-related symptoms were 18, 13, and 3%, respectively. Esophageal erosion occurred in 1% of patients, but its risk significantly increased for every year of MSA use (odds ratio - OR 1.40, 95%CI 1.11-1.77, p=0.004). Device removal was needed in 4% of patients. CONCLUSIONS: Although MSA is a very effective treatment modality for GERD, postoperative dysphagia is common and the risk of esophageal erosion increases over time. Further studies are needed to determine the long-term safety of MSA placement in patients with GERD.

The impact of Helicobacter pylori (HP) on postoperative outcomes after sleeve gastrectomy (SG) is still controversial. A systematic review and meta-analysis were performed to compare the incidence of early complications after SG between HP-positive and HP-negative patients. Eight retrospective comparative studies were included, comprising 4,877 individuals. The prevalence of HP infection in gastric resected specimens ranged from 7.77 to 43.20%. There were no statistically significant differences between groups for overall complications (OR 1.46; 95%CI 0.95-2.23; p=0.08), bleeding (OR 1.35; 95%CI 0.70-2.60; p=0.38), and leak (OR 1.74; 95%CI 0.80-3.81; p=0.17) rates. The need for routine screening and treatment of HP infection before SG remains ambiguous.

BACKGROUND: Colorectal cancer (CRC) is the most common malignancy of the gastrointestinal tract and the third most common type of cancer worldwide. The COVID-19 pandemic, during the years 2020 and 2022, increased the difficulties in offering adequate early diagnosis and treatment to CRC patients worldwide. During this period, it was only possible to treat patients who evolved with complications, mainly intestinal obstruction and perforation. AIMS: To assess the impact of the COVID-19 pandemic on the treatment of patients with CRC. METHODS: A review of data from a total of 112 patients undergoing emergency surgical treatment due to complications of CRC was carried out. Of these, 78 patients underwent emergency surgery during the COVID-19 pandemic (2020/2021), and 34 were treated before the pandemic (2018/2019). Ethnic aspects, clinical symptoms, laboratory tests, histopathological variables, intra and postoperative complications, and 90-day postoperative follow-up were compared between the two groups. RESULTS: Between the years 2018 and 2019, 79.4% (27/34) of patients had intestinal obstruction, while 20.6% (7/34) had intestinal perforation. During the period of the COVID-19 pandemic (2020/2021), 1.3% (1/78) of patients underwent surgery due to gastrointestinal bleeding, 6.4% (5/78) due to intestinal perforation, and 92.3% (72/78) due to intestinal obstruction. No statistically significant differences were recorded between the two groups in ethnic aspects, laboratory tests, type of complications, number of lymph nodes resected, compromised lymph nodes, TNM staging, pre or intraoperative complications, length of stay, readmission, or mortality rate. When considering postoperative tumor staging, among patients operated on in 2018/2019, 44.1% were classified as stage III and 38.2% as stage IV, while during the pandemic period, 28.2% presented stage III and 51.3% stage IV, also without a statistically significant difference between the two periods. Patients operated on during the pandemic had higher rates of vascular, lymphatic and perineural invasion. CONCLUSIONS: The COVID-19 pandemic increased the rate of complications related to CRC when comparing patients treated before and during the pandemic. Furthermore, it had a negative impact on histopathological variables, causing worse oncological prognoses in patients undergoing emergency surgery.

BACKGROUND: The laparoscopic approach considerably reduced the morbidity of colorectal surgery when compared to the open approach. Among its benefits, we can highlight less intraoperative bleeding, early oral intake, lower rates of surgical site infection, incisional hernia, and postoperative pain, and earlier hospital discharge. AIMS: To compare the perioperative morbidity of right versus left colectomy for cancer and the quality of laparoscopic oncologic resection. METHODS: Retrospective analysis of patients submitted to laparoscopic right and left colctomy between 2006 and 2016. Postoperative complications were classified using the Clavien-Dindo scale, 30 days after surgery. RESULTS: A total of 293 patients were analyzed, 97 right colectomies (33.1%) and 196 left colectomies (66.9%). The averageage was 62.8 years. The groups were comparable in terms of age, comorbidities, body mass index, and the American Society of Anesthesiology (ASA) classification. Preoperative transfusion was higher in the right colectomy group (5.1% versus 0.4%, p=0.004, p<0.05). Overall, 233 patients (79.5%) had no complications. Complications found were grade I and II in 62 patients (21.1%) and grade III to V in 37 (12.6%). Twenty-three patients (7.8%) underwent reoperation. The comparison between left and right colectomy was not statistically different for operative time, conversion, reoperation, severe postoperative complications, and length of stay. The anastomotic leak rate was comparable in both groups(5.6% versus 2.1%, p=0.232, p>0.05). The oncological results were similar in both surgeries. In multiple logistic regression, ASA statistically influenced the worst results (≥ III; p=0.029, p<0.05). CONCLUSIONS: The surgical and oncological results of laparoscopic right and left colectomies are similar, making this the preferred approach for both procedures.

BACKGROUND: To reduce the risk of regurgitation during anesthesia for elective procedures, residual gastric volumes (RGV) have traditionally been minimized by overnight fasting. Prolonged preoperative fasting presents some adverse consequences and has been abandoned for most surgical procedures, except for obese and/or diabetic patients. AIMS: The aim of this study was to assess the RGV in morbidly obese diabetic patients after traditional or abbreviated fasting. METHODS: This study was approved by the Ethics Committee for Research with Human Beings from the Federal University of Mato Grosso, under number 179.017/2012. This is a prospective, randomized, and crossover design study in eight morbidly obese type II diabetic patients. RGV was measured endoscopically after either traditional overnight fasting of at least 8 hours, or after abbreviated fasting of 6 hours for solids and 3 hours for a drink containing water plus 25 g (12.5%) of maltodextrin. Data were expressed as mean and range and differences were compared with paired t-tests at p<0.05. RESULTS: The study population had a mean age of 41.5 years (28-53), weight of 135 kg (113-196), body mass index of 48.2 kg/m2 (40-62.4), and type II diabetes for 4.5 years (1-10). The RGV after abbreviated fasting was 21.5 ml (5-40) vs 26.3 ml (7-65) after traditional fasting. This difference was not significant (p=0.82). CONCLUSIONS: Gastric emptying in morbidly obese diabetic patients is similar after either traditional or abbreviated fasting with a carbohydrate drink.

BACKGROUND: Patients with clinical stage IV gastric cancer may require palliative procedures to manage complications such as obstruction. However, there is no consensus on whether performing palliative gastrectomy compared to gastric bypass brings benefits in terms of survival. AIMS: To compare the overall survival of patients with distal obstructive gastric cancer undergoing palliative surgical treatment, using propensity score matching analysis. METHODS: Patients who underwent palliative bypass surgery (gastrojejunostomy or partitioning) and resection between the years 2009 and 2023 were retrospectively selected. Initial and postoperative clinicopathological variables were collected. RESULTS: 150 patients were initially included. The derived group (n=91) presented more locally invasive disease (p<0.01), greater degree of obstruction (p<0.01), and worse clinical status (p<0.01), while the resected ones (n= 59) presented more distant metastasis (p<0.01). After matching, 35 patients remained in each group. There was no difference in the incidence of postoperative complications, but the derived group had higher 90-day mortality (p<0.01). Overall survival was 16.9 and 4.5 months for the resected and derived groups, respectively (p<0.01). After multivariate analysis, hypoalbuminemia (hazard ratio - HR=2.02, 95% confidence interval - 95%CI 1.17-3.48; p=0.01), absence of adjuvant chemotherapy (HR=5.97; 95%CI 3.03-11.7; p<0.01), and gastric bypass (HR=3,28; 95%CI 1.8-5.95; p<0.01) were associated with worse survival. CONCLUSIONS: Palliative gastrectomy was associated with greater survival and lower postoperative morbidity compared to gastric bypass. This may be due to better local control of the disease, with lower risks of complications and better effectiveness of chemotherapy.

BACKGROUND: Hematological recurrence is the second most frequent cause of failure in the treatment of gastric cancer. The detection of circulating tumor markers in peripheral blood by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) method may be a useful tool to predict recurrence and determine the patient's prognosis. However, no consensus has been reached regarding the association between the tumor markers level in peripheral blood and its impact on patient survival. AIMS: To evaluate the expression of the circulating tumor markers CK20 and MUC1 in peripheral blood samples from patients with gastric cancer by qRT-PCR, and to verify the association of their expression levels with clinicopathological characteristics and survival. METHODS: A total of 31 patients with gastric adenocarcinoma were prospectively included in this study. CK20 and MUC1 expression levels were analyzed from peripheral blood by the qRT-PCR technique. RESULTS: There was no statistically significant (p>0.05) association between CK20 expression levels and clinical, pathological, and surgical features. Higher MUC1 expression levels were associated with female patients (p=0.01). There was a correlation between both gene levels (R=0.81, p<0.001), and CK20 level and tumor size (R=0.39, p=0.034). CONCLUSIONS: CK20 and MUC1 expression levels could be assessed by qRT-PCR from total peripheral blood samples of patients with gastric cancer. CK20 levels were correlated to MUC1 levels as well as to tumor size. There was no difference in disease-free survival and overall survival regarding both genetic markers expression in this series.

Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index above 35, age over 70 years, and the presence of comorbidities. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, a case-by-case analysis of surgical risk factors such as age, obesity, and comorbidities should be taken into consideration. Attention should also be paid to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual labor, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of large hiatal hernias in high-volume centers, with experienced surgeons.

BACKGROUND: Achalasia is an esophageal motility disorder, with clinical presentation of dysphagia and regurgitation. This is a chronic condition with no cure. Current treatment options aim to reduce lower esophageal sphincter tone by pharmacological, endoscopic or surgical means, with the aim of improving patients' symptoms. Peroral endoscopic myotomy (POEM) is an alternative endoscopic surgery to Heller cardiomyotomy, in which the procedure is performed orally, by endoscopy, offering efficacy comparable to surgical myotomy, with relative ease and minimal invasion, without external incisions. AIMS: To study the safety of POEM by analyzing its results, adverse events and perioperative complications and the main ways to overcome them, in addition to evaluating the effectiveness of the procedure and the short-term postoperative quality of life. METHODS: A qualitative and quantitative, observational and cross-sectional study that analyzed patients who underwent the POEM in a reference center, from December 2016 to December 2022, maintaining the technical standard of pre-, peri- and postoperative protocol. RESULTS: A total of 94 patients were included in the study, and only three had postoperative complications. The average early postoperative Eckardt score was 0.93 and the late 1.40, with a mean improvement of 7.1 in early results and 6.63 in late results (p<0.05). CONCLUSIONS: POEM can be reproduced with an excellent safety profile, significant relief of symptoms and improvement in esophageal emptying, and in quality of life.

BACKGROUND: Minimally invasive distal pancreatectomy (MIDP) is associated with less blood loss and faster functional recovery. However, the benefits of robotic assisted distal pancreatectomy (RDP) over laparoscopic distal pancreatectomy (LDP) are unknown. AIMS: To compare RDP versus LDP for surgical treatment of benign lesions, pre-malignant and borderline malignant pancreatic neoplasias. METHODS: This is a retrospective study comparing LDP with RDP. Main outcomes were overall morbidity and overall costs. Secondary outcomes were pancreatic fistula (PF), infectious complications, readmission, operative time (OT) and length of hospital stay (LOS). RESULTS: Thirty patients submitted to LDP and 29 submitted to RDP were included in the study. There was no difference regarding preoperative characteristics. There was no difference regarding overall complications (RDP - 72,4% versus LDP - 80%, p=0,49). Costs were superior for patients submitted to RDP (RDP=US$ 6,688 versus LDP=US$ 6,149, p=0,02), mostly due to higher costs of surgical materials (RDP=US$ 2,364 versus LDP=1,421, p=0,00005). Twenty-one patients submitted to RDP and 24 to LDP developed pancreatic fistula (PF), but only 4 RDP and 7 LDP experienced infectious complications associated with PF. OT (RDP=224 min. versus LDP=213 min., p=0.36) was similar, as well as conversion to open procedure (1 RDP and 2 LDP). CONCLUSIONS: The postoperative morbidity of robotic distal pancreatectomy is comparable to laparoscopic distal pancreatectomy. However, the costs of robotic distal pancreatectomy are slightly higher.

BACKGROUND: Bariatric surgery is the most effective option to reduce weight in morbid obesity patients. The techniques most employed are the restrictive surgery laparoscopic sleeve gastrectomy (LSG), surgical procedures of intestinal malabsorption, and both types (restrictive and intestinal malabsorption) such as the Roux-en-Y laparoscopic gastric bypass (RYLGB). AIMS: To determine if LSG is more effective than RYLGB for weight loss. METHODS: A systematic review and meta-analysis was carried out, including five clinical trials and sixteen cohorts comparing LSG versus RYLGB in weight loss and secondary outcomes: resolution of comorbidities, postoperative complications, operative time, hospital stay, and improvement in quality of life. RESULTS: Excess weight loss was 10.2% (mean difference [MD] 10.2; 95%CI -10.14; -9.90) higher in patients undergoing LSG than in patients submitted to RYLGB. Diabetes mellitus type 2 was resolved in 17% (relative risk [RR] 0.83; 95%CI 0.77-0.90) of cases, more significantly after LSG, arterial hypertension in 23% (RR 0.77; 95%CI 0.69-0.84), and dyslipidemia in 17% (RR 0.83; 95%CI 0.77-0.90). Postoperative complications were 73% higher in patients undergoing RYLGB (MD 0.73; 95%CI 0.63-0.83). The operative time was 35.76 minutes shorter in the LSG (MD -35.76; 95%CI -37.28; -34.24). Finally, the quality of life improved more in patients operated by LSG (MD 0.37; 95%CI -0.48; -0.26). CONCLUSIONS: The study demonstrated that LSG could be more effective than RYLGB in reducing the percentage of excess weight, comorbidities, postoperative complications, operative time, hospital stay, and in improving quality of life.

BACKGROUND: Achalasia is an esophageal motility disorder, and myotomy is one of the most used treatment techniques. However, symptom persistence or recurrence occurs in 9 to 20% of cases. AIMS: This study aims to provide a practical approach for managing the recurrence or persistence of achalasia symptoms after myotomy. METHODS: A critical review was performed to gather evidence for a rational approach for managing the recurrence or persistence of achalasia symptoms after myotomy. RESULTS: To properly manage an achalasia patient with significant symptoms after myotomy, such as dysphagia, regurgitation, thoracic pain, and weight loss, it is necessary to classify symptoms, stratify severity, perform appropriate tests, and define a treatment strategy. A systematic differential diagnosis workup is essential to cover the main etiologies of symptoms recurrence or persistence after myotomy. Upper digestive endoscopy and dynamic digital radiography are the main tests that can be applied for investigation. The treatment options include endoscopic dilation, peroral endoscopic myotomy, redo surgery, and esophagectomy, and the decision should be based on the patient's individual characteristics. CONCLUSIONS: A good clinical evaluation and the use of proper tests jointly with a rational assessment, are essential for the management of symptoms recurrence or persistence after achalasia myotomy.

BACKGROUND: Liver transplantation (LT) is the only treatment that can provide long-term survival for patients with acute-on-chronic liver failure (ACLF). Although several studies identify prognostic factors for patients in ACLF who do not undergo LT, there is scarce literature about prognostic factors after LT in this population. AIM: Evaluate outcomes of ACLF patients undergoing LT, studying prognostic factors related to 1-year and 90 days post-LT. METHODS: Patients with ACLF undergoing LT between January 2005 and April 2021 were included. Variables such as chronic liver failure consortium (CLIF-C) ACLF values and ACLF grades were compared with the outcomes. RESULTS: The ACLF survival of patients (n=25) post-LT at 90 days, 1, 3, 5 and 7 years, was 80, 76, 59.5, 54.1 and 54.1% versus 86.3, 79.4, 72.6, 66.5 and 61.2% for patients undergoing LT for other indications (n=344), (p=0.525). There was no statistical difference for mortality at 01 year and 90 days among patients with the three ACLF grades (ACLF-1 vs. ACLF-2 vs. ACLF-3) undergoing LT, as well as when compared to non-ACLF patients. CLIF-C ACLF score was not related to death outcomes. None of the other studied variables proved to be independent predictors of mortality at 90 days, 1 year, or overall. CONCLUSIONS: LT conferred long-term survival to most transplant patients. None of the studied variables proved to be a prognostic factor associated with post-LT survival outcomes for patients with ACLF. Additional studies are recommended to clarify the prognostic factors of post-LT survival in patients with ACLF.

BACKGROUND: Clinical features and outcomes of patients admitted to the intensive care unit due to acute abdomen are important to be investigated. AIMS: To evaluate the outcomes of critically ill subjects with acute abdomen according to etiology, comorbidity and severity. METHODS: Outcomes of 1,523 patients (878 women, mean age 66±18 years) consecutively admitted to a specialized gastrointestinal intensive care unit with different causes of acute abdomen from January 2012 to December 2019, were retrospectively evaluated according to etiology, comorbidity and severity. RESULTS: The most common causes of acute abdomen were obstructive and inflammatory, particularly large bowel obstruction (27%), small bowel obstruction (18%) and acute pancreatitis (17%). Overall mortality was 13%. Surgery was required in 34% of patients. Median length of stay in the hospital was 9 [1-101] days. On univariate analysis mortality was significantly associated with age, APACHE II, Charlson comorbidity index, requirement for surgery and malignancy (p<0.0001), but only APACHE II, Charlson comorbidity index and surgical interventional remained significant on multivariate analysis. CONCLUSIONS: Critically ill patients admitted to the intensive care unit with acute abdomen constitute a heterogeneous group of subjects with different prognosis. Mortality is more related to the severity of the disease, comorbidity and need for surgery than to the etiology of the acute abdomen.

BACKGROUND: Adhesive small bowel obstruction is one of the most common causes of surgical emergencies, representing about 15% of hospital admissions. Defining the need and timing of surgical intervention still remains a challenge. AIMS: To report the experience of using meglumine-based water-soluble contrast in a tertiary hospital in southern Brazil, comparing with the world literature. METHODS: Patients suspected of having adhesive small bowel obstruction, according to their clinical conditions, underwent an established protocol, consisting of the administration of water-soluble contrast, followed by plain abdominal radiograph within 12 hours and by a new clinical evaluation. The protocol was initiated after starting conservative management, including fasting and placement of a nasogastric tube, as well as intravenous fluid reposition. RESULTS: A total of 126 patients were submitted to the protocol. The water-soluble contrast test sensitivity and specificity after the first radiograph were 94.6 and 91.0%, respectively; after the second radiograph, these values were 92.3 and 100%. The general test values for sensitivity and specificity were 91.9 and 100%, respectively. CONCLUSIONS: The measure parameters evaluated in this study were similar to those found in the literature, contributing to endorse the importance of this test in the evaluation of patients with adhesive small bowel obstruction. The particular relevance of this study was the similar results that were found using a different type of meglumine-based contrast, which is available in Brazil.

BACKGROUND: Morbidity of liver resections is related to intraoperative bleeding and postoperative biliary fistulas. The Endo-GIA stapler (EG) in liver resections is well established, but its cost is high, limiting its use. The linear cutting stapler (LCS) is a lower cost device. AIMS: To report open liver resections, using LCS for transection of the liver parenchyma and en bloc stapling of vessels and bile ducts. METHODS: Ten patients were included in the study. Four patients with severe abdominal pain had benign liver tumors (three adenomas and one focal nodular hyperplasia). Among the remaining six patients, four underwent liver resection for the treatment of colorectal liver metastases, three of which had undergone preoperative chemotherapy. The other two cases were one patient with metastasis from a testicular teratoma and the other with metastasis from a gastrointestinal neuroectodermal tumor. RESULTS: The average length of stay was five days (range 4-7 days). Of the seven patients who underwent resections of segments II/III, two presented postoperative complications: one developed a seroma and the other a collection of abdominal fluid who underwent percutaneous drainage, antibiotic therapy, and blood transfusion. Furthermore, the three patients who underwent major resections had postoperative complications: two developed anemia and received blood transfusions and one had biloma and underwent percutaneous drainage and antibiotic therapy. CONCLUSIONS: The use of the linear stapler in hepatectomies was efficient and at lower costs, making it suitable for use whenever EG is not available. The size of the LCS stapler shaft is more suitable for en bloc transection of the left lateral segment of the liver, which is thinner than the right one. Further studies are needed to evaluate the safety of LCS for large liver resections and resections of tumors located in the right hepatic lobe.
