Laparoscopic excision of mesenteric cyst of sigmoid mesocolon
A 42-years old female patient was admitted for vague intermittent lower abdominal pain, mainly in hypogastrium and left iliac fossa since 1 year. Physical examination revealed a palpable mobile intra-abdominal lump in left lower quadrant and was bimanually palpable on per vaginal examination. All laboratory investigations were within normal limits (including CA 125). USG and CT revealed a well-defined cystic lesion of size 5 × 6 cm in posterior and superior to the bladder with no evidence of septations, calcification or enhancement on post-contrast studies, likely to be mesenteric cyst []. Both ovaries and uterus were found to be normal.\nLaparoscopic exploration was done to confirm the site and origin of the mesenteric cyst. Three trocars were used: a 10 mm trocar was placed at the midline, 2 cm below the umbilicus: two 5 mm trocar were placed lateral to the rectus abdominus muscle in the right and left lower quadrant. It revealed the presence of 5 × 6 cm cystic swelling arising from mesentery of sigmoid colon []. Cyst was dissected carefully from the mesentery by sharp and blunt dissection. After complete cyst excision, it was put into an endobag. Cyst was aspirated (clear fluid) and was then removed with the endobag through 10-mm trocar site. The final pathological diagnosis was benign lymphangioma. Patient was discharged on the first postoperative day. She was symptom-free at 2 years follow-up.
