To compare the results of laparoscopic cholecystectomy (LC) with those of open cholecystectomy (OC) in the treatment of acute cholecystitis.

The prevalence and severity of obesity in children and adolescents has been increasing in recent years at an unprecedented rate. Morbidly obese children will almost certainly develop severe comorbidities as they progress to adulthood, and bariatric surgery may provide the only alternative for achieving a healthy weight. The aim of this study was to assess the long-term outcomes and safety of laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB) as new treatment modalities for morbidly obese adolescents. We conducted a retrospective review of a prospectively collected database of all adolescent patients who underwent LSG and RYGB under IRB protocol at the Bariatric and Metabolic Institute in Cleveland Clinic Florida between 2002 and 2011. Patients were also contacted by phone, adhering to HIPAA regulations, and were asked to answer a survey. Eighteen adolescents had a bariatric procedure performed at this institution. The mean age was 17.5 years, the average weight was 293.1 lbs, and the average BMI was 47.2 kg/m2. The mean follow-up period consisted of 55.2 months. The postoperative weight at 55 months follow-up was 188.4 lbs and average BMI was 30.1 kg/m2. Fifteen of the patients were available for follow-up. Thirteen out of 16 (81%) comorbidities in patients available for follow-up were in remission following rapid weight loss. The long-term follow-up and perioperative morbidity shown in this study suggest that LSG and LRYGB appear to be safe and effective operations in morbidly obese adolescents.

Background: Since its approval, robotic surgery has been growing as a useful, promising and probably superior technique for many surgeries. The aim of this study is to expose and evaluate the results of a 6-year experience, of a single surgeon, with robotic assisted surgery, used for different gastrointestinal procedures throughout this years. Study Design: We conducted a retrospective revision of all consecutive robotic assisted gastrointestinal cases performed by a single gastrointestinal laparoscopic surgeon of the

Initial experience with robotic assisted revisional bariatric surgery Background: Robotics in bariatric surgery is a novel development in medical institutions in Chile. Revisional bariatric procedures have increased during the last years. There are no publications in our country related to the initial experience and results in robotic revisional bariatric surgery. The aim of this study is to describe the initial experience and short term outcomes with robotic revisional bariatric surgery. Study Design: We conducted a retrospective study of all consecutive robotic revisional bariatric surgeries performed by a single surgeon in Clínica Santa María in Santiago, Chile. We analyzed demographic characteristics and surgical outcomes, morbidity, mortality and length of hospital stay. Results: 59 revisional bariatric surgeries were performed, 11 reshaping of sleeve gastrectomy, 34 Roux in Y gastric bypass, 1 pouch reshaping of Roux in Y gastric bypass, 3 extractions of laparoscopic adjustable gastric banding, 1 of them with simultaneous sleeve gastrectomy, 5 laparoscopic adjustable gastric banding to patients with previous Roux in Y gastric bypass, 3 total gastrectomy, 1 resection of gastro-gastric fistula and 1 gastro enteral anastomosis. Mean age was 47.8 years. Average preoperative body mass index was 33.86 kg/m 2. Mean surgical time was 101.63 minutes. Postoperative complications were observed in 3 patients (5.08%). In 2 (3.39%) of this patient, reoperation was required. There were no deaths in this group. Average length of hospital stay was 3.6 days. Conclusion: Robotic revisional bariatric surgery is a novel technique that appears to be safe and effective.
