Laparoscopic Gastric Bypass: Development Of Technique, Respiratory Function, And Long-Term Outcome

Roux-en-Y gastric bypass (RYGBP) is the preferred operation for the treatment of morbid obesity by many surgeons. Hereby we present the process by which laparoscopic roux-en-Y gastric bypass developed at our institution.

Method

Perioperative morbidity was recorded from 150 consecutive morbidly obese patients operated upon by Roux-en-Y gastric bypass from August 1994 to March 2002. The first 76 consecutive patients have been followed up to 5 years postoperatively. A subgroup of 40 patients was recruited to evaluate the postoperative lung function in a randomized study between receiving and not receiving prophylactic chest physiotherapy.

Results

In the whole series, there were 4 conversions to open surgery, 5 leaks, 12 postoperative bleedings and 1 intestinal obstruction. 1 patient succumbed after developing acute dilatation of the bypassed stomach. Respiratory function deteriorated significantly in all patients in the early postoperative period, irrespective if given physiotherapy. During the follow-up period, 3 patients developed mechanical obstruction of the Roux limb. Another patient had a perforated ulcer at the proximal pouch. Weight reduction averaged 70% of excess body weight at 2 years after surgery.

Conclusion

Laparoscopic roux-en-Y gastric bypass is an effective treatment for morbid obesity. During the initial development, we experienced a number of serious complications. The complication rate decreased over time. Postoperative lung function was markedly impaired, but there were no beneficial effects of chest physiotherapy. Long-term weight loss after laparoscopic roux-en-Y gastric bypass seems to be comparable to what has been reported after open Roux-en-Y gastric bypass.

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
