Surgical management of duodenal leiomyomas.
Duodenal leiomyomas are rare neoplasms and when present are usually asymptomatic. There are, however, isolated case reports of such leiomyomas giving rise to complications including gastrointestinal hemorrhage and obstruction. The purpose of this study was to review the surgical experience with duodenal leiomyomas at a large tertiary referral center. A retrospective review was performed of all patients with histologically proven duodenal leiomyomas encountered from 1975 to 1995. Twelve patients with surgically treated duodenal leiomyomas were identified. There were eight men and four women with a mean age of 57 years (range 20-73 years) at diagnosis. Anemia was the presenting sign in 10 patients (83%). The mean hemoglobin level at presentation was 10.8 +/- 2.67 g/dl. Other presenting signs included melena (n = 5) and epigastric tenderness (n = 4). No patient had obstructive symptoms. Upper endoscopy visualized the lesion in 9 of 10 patients, but endoscopic biopsy provided an accurate histologic diagnosis in only two of six patients biopsied. All resected specimens underwent frozen section and permanent histopathologic analysis. Local excision was performed in eight patients, as benignancy was anticipated at surgical exploration and frozen section findings. Two patients underwent segmental duodenal resection with primary end-to-end anastomosis, and two patients underwent a Whipple procedure. There was no perioperative mortality. Morbidity was minimal. There was no tumor recurrence during a median follow-up of 8.4 years. Gastrointestinal blood loss is the most common complication of duodenal leiomyomas requiring surgical intervention. Small symptomatic leiomyomas with benign features may be safely treated with local excision.
