Mesenteric cyst: drained and marsupialised laparoscopically avoiding enterectomy.

1 of 2 DESCRIPTION A 61-year-old man attended the outpatient department with vague abdominal discomfort associated with left fl ank pain. After investigation, he was diagnosed with a symptomatic mesenteric cyst (MC). Ultrasound scan ( fi gure 1 ) of the abdomen revealed a 20×14×25 cm thinwalled peritoneal cyst. The cyst was laying between the spleen and the anterior aspect of the left kidney. The origin of the cyst was not identifi ed. CT scan ( fi gure 2 ) confi rmed the presence of a 25.7×14×20 cm cystic lesion. The left kidney was displaced posterior-inferiorly and the spleen was displaced superiorly. The CT was also unable to successfully determine the origin of this cyst. A diagnostic laparoscopy was the best option for the patient. Intraoperatively, the presence of the cyst was confi rmed. It was a MC close to the origin of small bowel mesentery. It contained 3.3 litres of straw coloured fl uid. The lining of the cyst was smooth and benign looking. Therefore, the cyst was drained and de-roofed laparoscopically and the drainage opening marsupialised. Images in...
