LMGB outcomes

LMGB: Outcomes from the first 100 cases of LMGB

There were no instances of post-operative leak rate and the mortality rate was 0%

The outcomes from the first 100 cases of laparoscopic mini gastric bypass at a single centre in the UK, revealed that the procedure is safe and effective and the outcomes comparable to those published in literature. Presented by Dr Chetan Parmar, who is from the Sunderland Royal Hospital, Sunderland, UK, the first unit within the National Health Service of United Kingdom to perform this procedure and the centre with the highest number of procedures to date. The research was presented at the 6th Annual Meeting of the British Obesity and Metabolic Surgical Society 21-23 January, in Newcastle, UK. 

The study researchers retrospectively analysed their prospectively collected data of first consecutive 100 LMGB procedures performed at their centre since October 2012. All operations were performed using a standardised laparoscopic approach with formation of a long lesser curve based gastric pouch and a gastroenterostomy at 2.0 meters from duodeno-jejunal flexure.

Seventy four percent of the patients were female and the mean age was 44 years. The mean weight at presentation to bariatric unit was 135.1kgs and mean BMI 48. Eleven of the patients had prior gastric balloon insertion and one patient had a prior sleeve gastrectomy.

The average post-operative stay was 3.1 days and the early complication rate was 1% (wound infection treated with antibiotics and leading to colitis). There were no instances of post-operative leak rate, and the readmission rate was 6%.

Mean weight of patients at up to two year follow up was 96.4kgs and average weight loss 38.9kgs. Three patients developed post-operative marginal ulcer and three patients required long-term (>30 day) reoperation; one marginal ulcer perforation; and two underwent diagnostic laparoscopy. The 30 day mortality was 0%.

“We consider MGB to be safe and effective operation with a leak and mortality rate of 0%,” said Parmar. “The weight loss was satisfactory and we report a marginal ulcer and reoperation rate lower than reported in the published literature. However, long term follow up results are awaited to confirm these promising initial outcomes.”

The co-authors of this study were Maureen Boyle, Will Carr, Neil Jennings, Kamal Mahawar, Shlok Balupuri and Peter Small.
