Surgical versus endoscopic resection of large sessile duodenal and papillary lesions

Data on the endoscopic resection of duodenal and papillary lesions less than 15 mm in size have been well supported by systematic studies. However, for large sessile lesions of the duodenum or papilla (LSL-D/P), surgery is often performed despite significant morbidity and mortality. This study aimed to compare the outcomes and costs between endoscopic and surgical resection of such lesions.

Patients who underwent endoscopic or surgical resection of LSL-D/P at Sir Run Run Shaw Hospital, School of Medicine, Zhejiang University from 2013 to 2017 were retrospectively analyzed. Endoscopic and surgical outcomes and costs were compared.

A total of 68 lesions were evaluated (47.1% of patients were male; mean lesion size 25 mm); 46 were treated by endoscopic resection, and 22 were managed by surgical resection. At the initial procedure, complete resection was achieved in 93.4%. Major complications (perforation, delayed bleeding, pancreatitis, infections and admission to the ICU) occurred in 15.3% of the endoscopic group and 22.6% of the surgical group. For recurrence at the first surveillance endoscopic examination, there was a 12.1% recurrence rate in the endoscopic group and a 5.3% recurrence rate in the surgical group (P = 0.654). Compared with surgical resection, regardless of lesion location, endoscopic resection had a shorter procedural time and hospital stay, a lower morbidity rate and was less costly.

In centers specialized in complex endoscopic resection, patients with LSL-D/P would likely benefit from advanced endoscopic management, which offers a lower morbidity profile and reduced costs.
