Total Reconstruction of the Afferent Loop for Treatment of Radiation-Induced Afferent Loop Obstruction with Segmental Involvement after Pancreaticoduodenectomy with Roux-en-Y Reconstruction

As the literature on afferent loop obstruction (ALO) after pancreaticoduodenectomy (PD) is very limited, standardized rules for its management do not exist. Herein, we report the case of a 65-year-old male patient with chronic ALO who had undergone PD with single Roux-en-Y limb reconstruction and adjuvant chemoradiation therapy for pancreatic head adenocarcinoma 2 years earlier. The patient was brought to the operating room with the diagnosis of radiation enteritis of the afferent loop with segmental involvement and concurrent hepaticojejunostomy (HJ) and pancreaticojejunostomy (PJ) stricture. Complete mobilization of the afferent loop, removal of the affected segment and reconstruction were performed. Reconstruction of the afferent loop was a one-way option for the surgeons because the Roux-en-Y reconstruction limited endoscopic access to the afferent loop, and the segmental radiation injury of the afferent loop ruled out bypass surgery. However, mobilization of the affected segment through a field of dense adhesions and revision of the HJ and PJ were technically demanding.
