A method of laparoscopic treatment of large adnexal cysts - Two port trocar suction.

Abstract

The size of the adnexal cyst is a limitation to perform laparoscopic adnexal surgery. Large adnexal cysts may constrain the surgery space and may increase the risk of inadvertent cyst rupture during the surgery. Here, we offer a method to solve the difficulty in laparoscopic management of large adnexal cysts. This is a retrospective study of 43 patients with large (≧10cm) adnexal cysts, managed laparoscopically at one center from October 2016 to October 2019. All the surgeries were performed by an experienced laparoscopic surgeon. Malignancy was excluded before the surgeries according to the sonographic features. Cystectomy or salpingo-oophorectomy was decided according to the age, the sonographic pattern of the cyst and the patients' willingness. A 2cm vertical incision was made at the umbilicus, and an open laparoscopy method was used to enter the peritoneal cavity. A wound protector was applied with a glove and two trocars being set up. The second wound was made at the left abdomen, and a 5mm trocar was inserted. Then the cyst was punctured by means of the 5mm trocar, and the content of the cyst was then soon aspirated by means of the air-flow hole of the trocar. Afterward, cystectomy or salpingo-oophorectomy was performed. Data are expressed as mean±standard deviation unless stated otherwise. The mean operative duration was 54.7±33.4min, and the result was shorter than the previous study (P<0.05, CI (-32.92,-12.38)) according to one sample t-test. Most estimated blood loss (EBL) was minimum. No obvious complication was found. Two-port trocar suction in laparoscopic management of large adnexal cysts is feasible after proper evaluation, and it takes short operative time.
