A bidirectional stapling technique for laparoscopic small bowel anastomosis.

BACKGROUND

Small bowel anastomoses can present a technical challenge during laparoscopic procedures, particularly gastric bypass procedures. Early small bowel obstruction (SBO) rates associated with such procedures occur in .7%-5.2% of patients. Herein, we describe how a bidirectional stapling technique moves the enterotomy to the center of the anastomosis, decreasing the chances of an afferent limb obstruction.

METHODS

A prospectively collected cohort of 2263 consecutive patients who underwent laparoscopic Roux-en-Y gastric bypass with bidirectional stapling of the small bowel anastomosis was evaluated for early SBO. All patients met the National Institutes of Health criteria for bariatric surgery.

RESULTS

Overall, 3 patients' perioperative courses were complicated by perioperative, early SBO (.13%). These instances were all attributable to intraluminal blood clots and not from inadvertent narrowing of the afferent limb. One was diagnosed on postoperative day 1 by upper gastrointestinal study (UGI); 2 were diagnosed on postoperative day 2 by computed tomography (CT) scan with oral contrast. All 3 patients' complications were managed with a laparoscopic operation.

CONCLUSION

The bidirectional stapling technique for small bowel anastomoses, with our modifications, is a rapid, well-tolerated, and effective technique that offers potential advantages over standard laparoscopic anastomotic techniques by reducing perioperative SBO complications.
