title: Gastroscopic-assisted laparoscopic wedge resection of B-cell gastric mucosa-associated lymphoid tissue (MALT) lymphoma.
abstract: Helicobacter pylori has been implicated as an etiologic agent for B-cell gastric mucosa-associated lymphoid tissue (MALT) lymphoma. This tumor is considered a low-grade entity with an associated indolent course. Some instances of tumor regression with adequate antibiotic treatment and irradication of H. pylori have been reported. Gastric malignancy and more specifically, lymphoma, should be considered in all patients with recurrent or nonhealing ulcers. Diagnostic and treatment strategies for these patients remain controversial. Two patients were evaluated, one for recurrent disease, another for a 3-cm nonhealing ulcer. Both patients refused total gastrectomy. Both patients underwent gastroscopy with simultaneous laparoscopic visualization. The mucosal lesions were identified and removed via laparoscopic stapled wedge resection. A combined endoscopic and laparoscopic approach can be considered as an alternative to radical surgery in the treatment strategy of these tumors. Wedge resection allows for staging and thorough pathologic classification. Further studies are necessary to define the natural history and the role of laparo-endoscopy in the diagnosis, staging, and treatment of B-cell gastric MALT lymphoma.
