Prevent Dilation of Gastrojejunostomy in Roux-en-Y Gastric Bypass
Use of Bio-Membrane Around Gastrojejunostomy in Laparoscopic Roux-en-Y Stomach Bypass
Preventing Dilation of Gastrojejunostomy in Roux-en-Y Gastric Bypass
A Silastic ring has been used to prevent dilation of the gastrojejunostomy in Roux-en-Y gastric bypass. The use of a bio-membrane may prevent dilation of the anastomosis without the risks associated with prostheses. The aim of this study was to evaluate the feasibility and safety of applying such a bio-membrane around the gastrojejunostomy in Laparoscopic Roux-en-Y gastric bypass.
We used a new bio-membrane, that is derived from porcine small intestinal submucosa (SIS) and acts as a scaffolding for the ingrowth of connective tissue. Over a 4-month period, 14 LRoux-en-Y gastric bypass patients had their proximal anastomosis wrapped with 10 x 2.5 cm SIS by a single surgeon. We compared these patients to a control group of Laproscopic Roux-en-Y gastric bypass patients matched for BMI.
The average age of the patients was 35.0 years (control group: 45.1 years). The patients had a mean initial BMI of 44.7 kg/m2 (+/- 5.9) standard error, and the control subjects had a mean initial BMI of 46.7 kg/m2 (+/- 6.5). SIS application took a mean time of 11 (+/- 3) minutes without any intraoperative complication. The median hospital stay was 3.5 days in the experimental group and 3.7 days in controls. Three patients developed a symptomatic stenosis at the gastrojejunostomy following surgery. In the control group there were two stenoses. At an average follow-up of 87 days (controls: 95 days), the mean reduction in BMI was 7.8 (+/- 0.8) kg/m2.
Application of SIS around the gastrojejunostomy in patients undergoing Laproscopic Roux-en-Y gastric bypass is feasible and safe. Further follow-up is required, however, to evaluate the effectiveness in preventing dilation of the anastomosis.

Laparoscopic or open bariatric surgery, such as gastric banding or bypass is not an easy solution to morbid obesity and weight loss. It is a serious surgical procedure, involving health risks. To produce lasting weight loss it requires a long-term patient commitment to eating a healthy diet and following a regular program of physical exercise. Life-long use of nutritional supplements may also be necessary. So, before deciding, discuss your options fully with your doctor. © 2003-2017 Bariatric-Surgery.Info - Terms - Contact - Information - Resources
