Laparoscopic treatment of an omental cyst misdiagnosed as an adnexal cyst: A case report
2010
Omental cysts are rare types of intra‐abdominal lesions closely related to mesenteric and retroperitoneal cysts, all of which have the same origin from lymphatic tissue. Omental cysts are usually benign and asymptomatic, or present with atypical clinical symptoms. Thus, differentiating omental cysts from diseases of the gastrointestinal system, including the gallbladder, duodenum, pancreas and gynecologic cysts is not easy. In recent years, successful laparoscopic diagnosis and resection of mesenteric and omental cysts have been reported. Mesenteric lymphangiomas, compared to simple mesenteric cysts, have a tendency to adhere to pelvic organs, so complete resection is difficult. We report a case of an omental cyst, which had been misdiagnosed pre‐operatively as an adnexal cyst, and laparoscopically‐treated using the twisting method without injury to adjacent organs, with a review of the literatures.
