Introduction: Giant intraabdominal cysts are very rare, and conventional treatment is full midline laparotomy. We present a case of complete laparoscopic extirpation of a giant ovarian cyst.
Case report: A 16-year-old female presented with progressive abdominal distension for 1-year along with early satiety, constipation, and significant weight loss. A CT scan showed a giant multiseptated cystic mass in the abdomen measuring 22.5 x 30 x 40.5 cm with significant mass effect causing intrahepatic ductal dilatation and right hydronephrosis. The mass was decompressed via a mini-laparotomy in a controlled fashion, removing 15 liters of fluid. A laparoscopic left oophorectomy was then performed. The postoperative course was uneventful, and the patient was discharged home on postoperative day 1 with minimal pain and tolerating a regular diet. Pathology examination revealed a mature cystic teratoma.
Conclusion: Giant ovarian cysts can be managed laparoscopically when a normal tumor marker profile and benign imaging appearance exclude the possibility of malignancy.
