We have compared the outcomes of laparoscopic total gastrectomy (LTG) and laparoscopic subtotal gastrectomy (LSG), both with modified D2 lymphadenectomies for the treatment of advanced gastric cancers. <strong>Aim:</strong> To compare the outcomes of laparoscopic (total and subtotal) gastrectomy with modified D2 lymphadenectomy for the treatment of gastric cancer, contributing to the literature regarding the overall survival of these patients and postoperative complications. <strong>Methods:</strong> From 1993 to 2014, 239 patients were operated on laparoscopic gastrectomy at our department. The routinely laparoscopic gastrectomy was performed in all patients with gastric cancer including those presenting with obstruction and bleeding. Data could be collected, on a retrospective way, from 2006 to 2014, from the medical records of 103 patients who underwent LSG (<em>n</em> = 72) or LTG (<em>n</em> = 31). We excluded patients with metastatic disease and those who could not have a complete tumor resection. <strong>Results:</strong> Most patients were in advanced stages of cancer. Adenocarcinoma was the most common find, with 43% of cases in stage IIA and 31% in stage IIIB. Intracorporeal Roux-en-Y or Billroth II anastomoses were employed. Postoperative complications, for LSG and LTG, were 18% and 35.4%;mortality rate, during hospital stay, was 4.9% and 7.7%;three-year survival rate, 53.1% and 59.3%;and five-year survival rate, 46.9% and 40.7%. Mean hospital stay was 7.08 days, being significantly lower in LSG group (<em>p</em> < 0.05). Hospital acquired pneumonia was the most prevalent clinical complication, while deaths arising from surgical complications were caused mainly by gastro-jejunal or esophago-jejunal anastomosis leaks. <strong>Conclusions:</strong> Both LSG and LTG with modified D2 lymphadenectomy are feasible alternatives to open surgery and survival rates were comparable. The increased risk of complications observed in LTG did not influence the overall mortality rate. We hope that these findings should contribute to improve the acceptance of laparoscopic gastrectomy as a safe procedure for gastric cancer treatment.展开更多

The management of complications after bariatric surgery is still a challenge. The study aims to report the incidence of portomesenteric venous thrombosis (PMVT) in patients undergoing bariatric surgery. Introduction: Bariatric surgery is the procedure of choice for the treatment of obesity type III. Despite the safe technique, the surgeon must be aware of the risks linked to laparoscopy such as the PMVT. Computed tomography (CT) with intravenous contrast was the imaging method of choice for diagnosis. Materials and Methods: We performed a retrospective analysis of 4790 patients from August 1999 to June 2020 was observed the incidence of PMVT in this group. Of all patients, 72.8% were female and 27.2% male. The mean age was 46.3 years (34 - 72) and the mean BMI before bariatric surgery was 41.4 kg/m<sup>2</sup>. Results: The study showed an incidence of PMVT of 0.12% (N = 6), portal vein thrombosis was of 0.10% (n = 5) and 0.03% of MVT (n = 1). Of these, 72.5% (n = 3473 patients) underwent laparoscopic gastric bypass, 23.6% (n = 1131 patients) were submitted to the laparoscopic sleeve gastrectomy and 3.8% (n = 186 patients) to other procedures. The mean postoperative hospital stay for bariatric surgery was 3.3 days. The average time of hospital stay of patients complicated with PMVT range from 5 to 14 days. No patient died of complications related to PMVT. Conclusion: Portomesenteric vein thrombosis is a rare presentation after laparoscopic bariatric surgery. However, it is a serious complication that has a high index of suspicion for making its diagnosis. Conservative treatment using anticoagulants and thrombolytics is effective, it should always be considered the main treatment option. However, these patients must be followed up in the long term, as late complications can occur in high numbers of patients.展开更多
