Shortening and Plication of Entero-enterostomy for Intussusception in Roux-en-Y Gastric Bypass: Video Report.

Abstract

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is considered by a large percentage of bariatric surgeons' the operation of choice for obesity surgery as reported by Melvin (J Gastrointest Surg. 4:398-400, 2004). It is considered a generally safe procedure with a low percentage of complications. One of these complications is small bowel obstruction which has different etiologies. A rare cause of intestinal obstruction is intussusception at the entero-enterostomy as reported by Arapis et al. (Surg Obes Relat Dis. 1:23-33, 2019) and Sneineh et al. (OBES SURG 30:846-850, 2020). The accurate incidence of intussusception after LRYGB is unknown but Simper et al. (Surg Obes Relat Dis. 4:77-83, 2008) found a 0.15% incidence in their study. Diagnosis of intussusception requires a high index of suspicion because neither physical examination nor imaging is sensitive. CT scan might identify the problem, but a negative CT scan image does not rule out intussusception. Treatment of intussusception varies according to the clinical picture of the patient at the presentation. These variations may include conservative treatment up to resection of the entero-enterostomy and do a re-anastomosis as discussed by Daellenbach et al. (OBES SURG 21:253-263, 2011). The video aims to present an alternative option for surgical management of intussusception of the entero-enterostomy following LRYGB which to our knowledge was not published before.
