Nomogram for predicting difficult total laparoscopic hysterectomy: a multi-institutional, retrospective model development and validation study.

Background: Total laparoscopic hysterectomy (TLH) is the most commonly performed gynaecological surgery. However, the difficulty of the operation varies depending on the patient and surgeon. Subsequently, patient's outcomes and surgical efficiency are affected.

A preoperative scoring system to predict the probability of laparoendoscopic single-site extracorporeal cystectomy in patients with benign ovarian cysts.

Objective: To develop a preoperative scoring system (PSS) to predict whether laparoendoscopic single-site extracorporeal (LESS-E) cystectomy can be performed in patients with benign ovarian cysts.

Method: We reviewed data on patients who underwent LESS cystectomy between August 2016 and October 2019 at the first Affiliated Hospital, Army Medical University. The independent predictors of LESS-E cystectomy in patients with benign ovarian cysts were identified using multivariate logistic regression analyses.

Perioperative outcomes of laparoendoscopic single-site extracorporeal versus intracorporeal cystectomy for benign ovarian cysts: a retrospective cohort study based on propensity score matching.

Background: Ovarian cysts are the most common gynecological disease, and laparo-endoscopic single-site (LESS) cystectomy is a popular surgical procedure. A new laparoscopic technique combining the advantages of LESS surgery and open surgery has been introduced to treat large ovarian cysts. To our knowledge, no previous research has compared LESS-extracorporeal (LESS-E) cystectomy to LESS-intracorporeal (LESS-I) cystectomy.
