Laparoscopic Single-site In-bag Ovarian Dermoid Cystectomy in a 16-week- pregnant Patient

Study Objective: To demonstrate a novel in-bag ovarian cystectomy technique fora large adnexal mass in pregnancy. Design: Stepwise demonstration with narrated video. Setting: An academic tertiary care hospital. The patient was a 26-year-old woman, gravida 1, para 0, at gestational age of 7 weeks and 3 days who presented to the emergency department with persistent left pelvic pain and was diagnosed with a 16 cm x 10 cm x 12 cm dermoid cyst. She re-presented at gestational age of 16 weeks and 3 days with worsening pelvic pain, and the decision was made to proceed with surgical intervention. Interventions: Laparoscopic transumbilical single-site surgery for the surgical management of adnexal masses in pregnancy has been demonstrated to be feasible and safe [1-3]. However, single-site laparoscopic ovarian cystectomy can be very challenging in pregnancy, especially when the need for suturing arises. Exteriorizing the ovary and cyst after intraperitoneal drainage may allow for extracorporeal suturing that is faster and easier; however, it may increase the probability of spillage of cystic contents if it is not performed in a bag, which can then cause peritonitis in cases of dermoid cysts. A combination of in-bag and extracorporeal ovarian cystectomy is a novel alternative minimally invasive approach that is cosmetic, safe, and effective. Several helpful techniques in this novel combination technique include the following: Creating an umbilical incision of at least 2 cm or one that is large enough for better manipulation of both the surgical bag and adnexal mass. Tightening the bag appropriately around the infundibulopelvic ligament so that it is not too tight leading to compromised blood supply and tissue necrosis, yet not too loose resulting in leakage of cystic contents. Ensuring that the infundibulopelvic ligament is stabilized within the surgical bag. Inserting small-sized wound retractor into the bag for better exposure during cystectomy. Having a double-suction irrigation setup for large adnexal masses, as demonstrated in this patient, to reduce the spillage of cystic contents. The procedure was successfully performed in approximately 110 minutes, and the fetal heart rate postprocedure was 128 bpm through bedside transabdominal ultrasound. Estimated blood loss was 5 mL, and the patient was discharged the same day with an uneventful 4-week postoperative follow-up. Conclusion: Laparoscopic single-site in-bag ovarian dermoid cystectomy is feasible, effective, and safe in pregnant patients with a large adnexal mass. This technique results in better stabilization of the ovarian cyst and reduction of cystic content spillage. (C) 2021 AAGL. All rights reserved.

Automated summary

The study demonstrated a novel technique for ovarian cystectomy in pregnant patients with a large adnexal mass by combining in-bag and extracorporeal approaches. This approach was found to be safe, effective, and able to reduce spillage of cystic contents, providing better stabilization of the ovarian cyst.
