Jejuno-gastric intussusception: A case report of unusual cause of food intolerance after roux-En-Y gastric bypass.

BACKGROUND

Morbid obesity is increasing worldwide as a result, weight loss procedures such as Roux- En-Y gastric bypass (RYGB) are increasing as well. RYGB has multiple complications including intussusception, most of the cases are jejuno-jejunal. Only one case reported to be Jejuno-gastric intussusception (JGI) but through the remnant and not the gastro-jejunostomy anastomosis (GJ).

METHODS

A 50-year-old female presented to the emergency department complaining of diffuse abdominal pain, nausea, and vomiting. Her surgical history is significant for an RYGB 17 years ago. Nausea and food intolerance were the most prominent symptoms. CT scan of the abdomen and upper GI series were normal. Only Esophagogastroduodenoscopy (EGD) showed JGI through GJ, with friable mucosa and a small gastro-gastric fistula. Patient underwent successful reconstruction of GJ and had no symptoms afterwards.

CONCLUSIONS

JGI is a rare of cause of abdominal pain, nausea and vomiting after RYGB. Early diagnosis is crucial, a thorough work up is needed to make diagnosis of JGI including EGD. Revision of GJ anastomosis is necessary to address this phenomenon.
