BACKGROUND

Laparoscopic gastric bypass (LGBP) is the most common bariatric procedure worldwide. The gastrojejunostomy can be stapled with a circular or linear stapler, each with their own specific advantages. We have evaluated differences in postoperative complications between the two techniques.

METHODS

We studied operative data and postoperative complications in 560 patients (79.8 % females, median age 42, BMI 42.5) operated with LGBP between 2008 and 2012 at our center. The gastrojejunostomy was initially performed using a circular stapler (CS) in 288 patients and later by linear stapler (LS) in 272. Complications, operative time, and length of stay were retrieved from our database. The risk of developing a port site infection was evaluated with multivariate logistic regression.

RESULTS

Port site infections were more common with CS than LS, 5.2 and 0.4 %, respectively (p < 0.01). Multivariate analysis demonstrated CS to be an independent risk factor for port site infections (OR 16.3 (2.09-126), p < 0.01), as well as for stomal ulcers (OR 10.1, 1.15-89, p = 0.04). Major postoperative complications remained unchanged (anastomotic leak 1.0 vs. 1.1 %, abscess 0.7 vs. 0.4 %), while operative time and length of stay were found to be shorter using the LS (122 vs. 83 min, p < 0.001 and 4 vs. 3 days, p < 0.001).

CONCLUSIONS

The linear stapled technique yielded lower incidence of port site infections, probably by avoiding the passage of a contaminated circular stapler through the abdominal wall. No difference in major complications was seen, but operative time was shorter using a linear stapler instead of a circular stapler.

Abstract [en]

Roux-en-Y gastric bypass (RYGBP) achieves superior short- and long-term weight loss compared to other weight loss modalities. Different operative techniques have been developed to technically facilitate the surgical procedure, with consequences in the form of an array of postoperative complications and gastrointestinal symptoms. Furthermore, as our follow-up on operated patients extends beyond the first postoperative years, it becomes apparent that a significant number of patients experience unsatisfactory weight result. Current research is just starting to chart factors associated with postoperative long-term weight regain with the ultimate goal of preventing it.

In Paper I it is found that the linear stapled technique for the gastrojejunostomy in laparoscopic RYGBP is associated with shorter operative time, in-hospital stay and a lower incidence of surgical site infections and anastomotic strictures compared to the circular stapled technique. Paper II demonstrates that, despite no differences in weight result, the 21-mm circular stapled technique for the gastrojejunostomy is associated with a higher incidence of vomiting and endoscopic anastomotic dilatations compared to the 25-mm circular stapled technique and the linear stapled technique in the long-term after RYGBP. Paper III shows that despite differences in body composition, long-term weight responders and non-responders after RYGBP did not differ in resting, glucose-induced or activity-related energy expenditure. Lastly Paper IV shows long-term weight result is associated with fasting levels of leptin and ghrelin, and that the response of these hormones to a glucose load might contribute to perpetuate obesity.
