Laparoscopic wedge resection with SAMIT is technically and oncologically safe. It is useful for treating gastric gastrointestinal stromal tumors, including those close to the esophagogastric junction or pyloric ring.
We report herein the case of a giant lipoma of the greater omentum that was treated by laparoscopic surgery. A 71-year-old male patient was admitted with a diagnosis of sigmoid colon cancer. During preoperative examination, a gallbladder stone and an intra-abdominal giant lipoma were accidentally diagnosed. Laparoscopic examination revealed a smooth-surfaced, giant yellow tumor at the lower border of the greater omentum that was unattached to the surrounding organs. After laparoscopic resection of the tumor and cholecystectomy, a 10-cm midline incision was made in the lower abdomen to remove the tumor and the gallbladder. We then performed a sigmoidectomy for sigmoid colon cancer through the same laparotomy. The resected tumor measured 29 x 19 x 3 cm and weighed 1250 g, and a histopathologic examination revealed a benign lipoma. Laparoscopic examination and resection of a giant lipoma of the omentum are particularly useful.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
