What Every Bariatric Surgeon Should Know: How to Relieve Obstruction at the Jejuno-jejunostomy After Roux-en-Y...

Roux-en-Y gastric bypass (RYGB) remains one of the key bariatric procedures worldwide. In addition to bleeding and anastomotic leak, there are rarely occurring complications such as obstruction at the jejuno-jejunostomy in the early postoperative phase.

A 51-year-old lady (weight 122 kg; BMI 46 kg/m²; with type 2 diabetes mellitus and hypertension) underwent RYGB in our tertiary referral centre 3 days prior to admission. She originally recovered well from the uneventful operation, but began vomiting on day 3. At this point, she complained of no other symptoms. An urgent CT scan identified a gastric remnant dilatation, and an obstructed jejuno-jejunostomy. An urgent laparoscopic exploration was performed, which identified obstruction at this level.

Within our video-presentation, detailed technical steps are described. First, gastric remnant decompression was performed by inserting a tube gastrostomy. Secondly, the obstruction was identified. Consequently, a new jejuno-jejunostomy was created, proximal to the original anastomosis, using a linear stapler, and direct suture closure of the enterotomy defects. After thorough washout, drains were placed in the pelvis and alongside the jejuno-jejunostomy. The patient was discharged home after a 2-week hospital stay which included 5 days of invasive ventilation on the ITU.

A high-level of suspicion is required to suspect, diagnose and treat post-RYGB complications. A bariatric on-call rota with appropriately trained personnel is essential.
