Abstract

Background

Afferent loop obstruction (ALO) is a rare mechanical complication of pancreaticoduodenectomy (PD) and is associated with a high rate of morbidity and mortality.

Methods

Data from patients who underwent PD between May 2007 and July 2017 at a single large-volume center were retrospectively reviewed.

Results

Of the 3,223 patients who underwent PD, 67 developed ALO. More patients in the laparoscopic PD (LPD) group had developed ALO due to internal herniation than did those in the open PD (OPD) group (46.2 vs. 4.7%, P < 0.001). Patients in the LPD group also showed earlier occurrence of ALO (ALO occurrence within 60 days: 76.9 vs. 22.2%, P < 0.001) and more frequent requirement for surgical treatment (76.9 vs. 18.9%, P < 0.001) than did those in the OPD group.

Conclusions

The characteristics of ALO were significantly different between patients who had received LPD and OPD. The most common cause of ALO in the LPD group was internal herniation occurring in the early postoperative period. Internal herniation following LPD may be prevented by routine closure of mesocolic window and should be treated by emergency surgery if it occurs.
