Abstract
BACKGROUND: Candy cane syndrome (CCS), which is also called Roux syndrome, is a rarely reported and neglected complication of proximal Roux-en-Y gastric bypass (RYGB) surgery. METHODS: Forty-seven cases of CCS that underwent candy cane (CC) resection were analyzed retrospectively for pain remission to determine whether intussusception is a possible underlying mechanism. RESULTS: Forty-three patients (89.6%) benefited from laparoscopic CC resection (p < 0.001). The highly sensitive diagnostic tests were upper gastrointestinal series (91%) and gastroscopy (96%). Intussusception of the CC into the gastric pouch was demonstrated in most cases and was postulated as the trigger for CCS. In some cases, retroperistaltic intussusception led to nonspecific upper gastrointestinal bleeding. CONCLUSION: A vast majority of CCS cases benefited significantly from CC resection. The long-described retroperistaltic intussusception of the CC was suggested as an important underlying mechanism of the symptoms. Although CC resection remains a stopgap, evidence on its clinical significance has been shown for a century. Building on this wealth of experience and the already vast storage of practical knowledge, awareness of this underestimated complication after RYGB should be raised.
