Candy cane syndrome at jejunojejunostomy causing small bowel obstruction following revisional laparoscopic gastric bypass: A case report and review of literature.

Abstract

Introduction and importanceThe literature described Candy cane syndrome (CCS) as causing various symptoms and affecting patients' quality of life. Most of the literature described this syndrome occurrence at gastrojejunostomy (GJ) anastomosis. The literature lacks data on this syndrome occurring at the jejunojejunostomy (JJ).Case presentationWe describe a patient who underwent revision of laparoscopic gastric bypass (LGB) due to weight regain and presented three days after the procedure with small bowel obstruction (SBO). The patient was admitted as she demonstrated a picture of SBO. A complete workup and contrast study was done and showed dilated bowel loops. The patient was taken for exploratory laparoscopy, which revealed dilated 10–15 cm candy cane near the JJ, causing and obstruction. Resection of the elongated blind pouch was done, and the patient tolerated the surgery with improvement in her symptoms. Preoperative imaging, perioperative management, procedure videos, and follow-up were used to describe the case.Clinical discussionAfter reviewing the literature, eight papers reported CCS, 7 of those articles mentioned the syndrome located at the GJ. CCS located near the JJ can lead to symptoms including SBO. Management is mainly surgical, and prevention of occurrence can be achieved by limiting unnecessary elongated blind pouches.ConclusionCCS is a well-established condition occurring at the GJ following LGB, but it can manifest similarly if an elongated blind limb is left unresected at the JJ.
