Laparoscopic resection of malignant gastric polyp-with a particular emphasis on localization by laparoscopic...

Adenomatous polyps of the stomach are rare and usually found on routine endoscopic examination. These polyps should be removed because of their potential for malignant transformation. Endoscopic polypectomy is the preferred treatment modality, but a laparotomy is required to resect large polyps. This study presents a case of a large gastric polyp containing carcinoma in situ that was successfully managed by laparoscopic gastrectomy. With the use of a novel technique, the tumor was localized by intraoperative laparoscopic ultrasonography. The patient had an excellent postoperative recovery, and follow-up endoscopy at 24 months revealed no recurrent tumor.
