# Intussusception of Gastrojejunostomy After Pancreatoduodenectomy With Billroth II Reconstruction

## TL;DR

This paper reports a rare case of intussusception after a pancreatoduodenectomy surgery and describes the emergency treatment used.

## Contribution

The paper presents a rare complication in hepatopancreaticobiliary surgery and its management.

## Key findings

- Intussusception of the gastrojejunostomy is a rare but significant complication after pancreatoduodenectomy.
- Emergency surgical treatment was effective in managing the complication in the presented case.

## Abstract

Gastrojejunal anastomosis or gastrojejunostomy (GJ) is a surgical procedure used for allowing gastric emptying, especially in cases where complex reconstructions are needed. One of the less common complications but one of the most relevant in morbidity is the intussusception of the GJ. It requires a high index of suspicion, preoperative optimization of the patient, diagnostic corroboration, and identification of associated complications with the use of contrasted imaging. It was described for the first time by Bozzi in 1914; currently, multiple cases have been described in the literature, being more frequent in bariatric surgeries and reconstructions after distal gastrectomy. In hepatopancreaticobiliary surgery, it is an even uncommon complication. We present the case of a 60-year-old man with intussusception of the efferent loop of the GJ after a pylorus-preserving pancreatoduodenectomy with a Billroth II reconstruction in the setting of malignancy of the extrahepatic bile duct along with our emergency surgical treatment.
