Laparoscopy-assisted distal gastrectomy for gastric malignant lymphoma.

Although the best treatment for gastric malignant lymphoma remains a controversial matter, surgery is the first choice for localized malignant lymphoma without lymph node metastasis and invasion to the adjacent organ. We report a case of gastric malignant lymphoma that was managed with laparoscopy-assisted distal gastrectomy. A 47-year-old man was referred to our department for management of gastric lymphoma. After preoperative examination revealed a tumor confined to the gastric wall but no lymph node metastasis, we performed laparoscopy-assisted Billroth I gastrectomy. Histopathologic examination confirmed that the tumor was follicular center lymphoma limited to the submucosa with no lymph node metastasis. The postoperative course was good. This is the first reported case of laparoscopic gastrectomy-treated gastric malignant lymphoma. Because it involves minimal access and invasiveness, this procedure may be an effective method of treatment of localized malignant lymphoma of the stomach.
