Laparoscopic Roux-en-Y gastric bypass complicated by a mesocolic jejunal stricture successfully treated with endoscopic TTS balloon dilation.

Even though Roux-en-Y gastric bypass is the most commonly performed bariatric surgery in the United States, it is not without post surgical complications. The development of a mesocolic jejunal stricture after a laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a rare complication. We present a patient who manifested, at 5 weeks post-LRYGBP, symptoms of nausea, vomiting, and an inability to tolerate an oral diet. The patient was found to have a stricture at the efferent Roux limb consistent with a mesocolic stricture which was successfully resolved with through the scope (TTS) balloon dilatation. There was no apparent cause of the patient's stenosis with no evidence of an anastomotic breakdown or major inflammatory process. The patient presented for follow-up after her dilatation was noted to have complete resolution of her symptoms and continued to lose weight. This is the first known case of a mesocolic jejunal stricture successfully treated with TTS balloon dilation.
