Value of endoscopic submucosal dissection for duodenal lesions in 78 patients / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To assess the clinical value of endoscopic submucosal dissection(ESD) for duodenal lesion.</p><p><b>METHODS</b>A total of 78 patients with duodenal lesion were treated with ESD from November 2006 to August 2010. The clinical data were retrospectively analyzed.</p><p><b>RESULTS</b>There were 46 male and 14 female patients. The mean age was(54±9) years. The lesion location included the duodenal bulb(n=39, 50%), the junction of bulb and descending part(n=19, 24.4%), and the descending part(n=20, 25.8%). The mean diameter of the lesions was(2.1±1.7) cm. Fifty-one(65.4%) lesions originated from the mucosa, including inflammatory/ hyperplastic polyps(n=22, 28.2%), villous/tubular adenoma(n=26, 33.3%), and hamartomas polyps(n=3, 3.8%). Twenty-five(32.1%) lesions originated from the submucosa, including Brunner's glands adenoma(n=15, 19.2%), ectopic pancreas(n=3, 3.8%), carcinoid tumor(n=3, 3.8%), lipoma(n=2, 2.6%), myxoinoma(n=1, 1.3%), and angio-lymphangioma(n=1, 1.3%). There were two lesions originated from the muscularis propria(n=2, 2.5%), and both were ectopic pancreas. All cases received ESD successfully. The mean operative time was(37±41) min and the mean blood loss was(23±15) ml. The perioperative complication rate was 35.9%(28/78), including intraoperative perforation(n=6), delayed perforation(n=3), intraoperative hemorrhage(n=10), delayed bleeding(n=7), and transient elevation of serum amylase(n=2). Postoperative pathological examination showed vascular invasion with tumor cells in one patient, who received extended resection later. The remaining 77 patients showed no recurrence during the followed up(rang, 3-23 months) using endoscopy.</p><p><b>CONCLUSION</b>ESD is an effective, safe, minimally invasive method for the management of duodenal lesions.</p>
