Background and aims: This retrospective study aimed to evaluate the effect and safety of endoscopic submucosal dissection (ESD) for large laterally spreading lesions located in the descending duodenum based on multi-center experiences.
Methods: This multicentric retrospective study included 3 hospitals in China. Fifty-one patients with laterally spreading lesions of the duodenum who underwent ESD between February 2019 and December 2020 were enrolled. The en bloc resection rates, en bloc R0 resection rates, complication rates, and local recurrence after ESD were evaluated.
Results: Of the 51 patients, the median age was 62 years old (ranging from 37 to 76 years old); among them, 29 were male and 22 were female. The average lesion size was 2.3 cm (ranging from 1.5 to 4.0 cm). All 51 lesions achieved en bloc R0 resection successfully, with the procedure time ranging from 20 to 117 min (median: 45.5 min). The hospital length of stay ranged from 4 to 90 days (median: 8.0 d). Two patients experienced delayed bleeding 3 days after ESD and 2 other patients were diagnosed with delayed perforation. Tumor residual and local recurrence did not occur during a short follow-up period.
Conclusions: ESD for laterally spreading lesions of the descending duodenum is feasible.
