Laparoscopic Roux-en-Y gastric bypass versus laparoscopic mini gastric bypass in the treatment of obesity: study protocol for a randomized controlled trial.

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is considered the gold standard in bariatric surgery, achieving durable long-term weight loss with improvement of obesity-related comorbidities. Lately, the laparoscopic mini gastric bypass (LMGB) has gained worldwide popularity with similar results to LRYGB in terms of weight loss and comorbidity resolution. However, there is a lack of randomized controlled trials (RCT) comparing LMGB and LRYGB.

Intraoperative Patterns of Gastric Microperfusion During Laparoscopic Sleeve Gastrectomy.

Background: Laparoscopic sleeve gastrectomy (LSG) has become a very popular surgical treatment for the treatment of morbidly obese patients. Staple line leaks are the major cause of severe morbidity. Reasons for leaks might be hyperpressure (mechanical theory) or hypoperfusion (vascular theory) of the narrow gastric tube.

Primary non-closure of mesenteric defects in laparoscopic Roux-en-Y gastric bypass: reoperations and intraoperative findings in 146 patients.

Background: Internal hernias (IH) after laparoscopic Roux-en-Y gastric bypass (LRYGB) have been reported with an incidence of 11 %. IH can lead to bowel incarceration and potentially bowel necrosis. The aim of this study was to analyze reoperations and intraoperative findings in a cohort of patients with unclosed mesenteric defects.

Effect of a post-operative structured exercise programme on short-term weight loss after obesity surgery using adjustable gastric bands.

Background: Exercise has been recommended as an adjunct to diet control to achieve weight loss. No previous studies in the area had formal exercise guidelines or education [1, 2]. Unique to our practice is Bandfit, a personal trainer-led exercise programme for patients following bariatric surgery.

Pathologies of the appendix: a 10-year review of 4670 appendicectomy specimens.

Background: Debate surrounds the management of the macroscopically normal appendix. Current literature recommends its removal given the high incidence of microscopic appendicitis, and other unusual pathologies in the normal-looking appendix. Negative appendicectomies are reported on the decline with increased use of diagnostic radiological adjuncts.

Outcomes after admission on the day of elective resection for colorectal cancer.

Background: When a policy encouraging day of surgery admission (DOSA) was introduced in public hospitals in New South Wales, Australia, there were concerns that patient outcomes would be compromised. The aim of the present study was to compare patients having an elective resection for colorectal cancer (CRC) on a DOSA and a non-DOSA basis in respect of postoperative complications, operative mortality and 2-year survival.

Methods: A comprehensive prospective computerized database is maintained for all patients undergoing a resection for CRC at Concord Hospital, Sydney, Australia.
