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

ABSTRACT:

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. This study compared the perioperative results of LESS-E cystectomy and LESS-I cystectomy in the treatment of benign ovarian cysts.

Methods

Two hundred eighty-eight cases of cystectomy from our institutional database were retrospectively reviewed. 1:1 propensity score matching (PSM) was performed to minimize bias due to any imbalanced baseline features between the 2 groups, which were matched in terms of age, body mass index, and the largest diameter of ovarian cysts. Seventy-nine cases were then selected from each group, and the perioperative outcomes of the 2 cohorts were analyzed.

Results

The mean (standard deviation) largest diameter of ovarian cysts was 8.30 (3.56) cm in the LESS-I group and 9.14 (3.15) cm in the LESS-E group (P=0.118). No statistically significant difference was found between the 2 groups in terms of estimated blood loss, postoperative hemoglobin decline, postoperative pain in 24 hours, postoperative hospital stay, and total hospital costs (P>0.05). However, the mean operation time of the LESS-E group was shorter than that of the LESS-I group (85.01 vs. 104.25 minutes; P=0.001). Additionally, the spillage rate of the LESS-I group was significantly greater than that of the LESS-E group (46.8% vs. 17.7%; P<0.001). The mean pain scores at 6 postoperative hours as measured by a visual analogue scale were significantly greater in the LESS-I group than the LESS-E group (3.85 vs. 3.37; P=0.016).

Conclusions

LESS-E cystectomy is a safe and feasible approach with a shorter operation time and lower spillage rate than LESS-I cystectomy.

Project description:ObjectiveTo investigate the prognostic significance of metabolic syndrome (MetS) and its components in patients with bladder cancer (BCa) treated with radical cystectomy (RC).MethodsA total of 335 BCa patients who underwent RC between 2004 and 2019 at Peking University Third Hospital (PUTH) were analyzed retrospectively. The Kaplan-Meier method with the log-rank test was performed to assess overall survival (OS) and progression-free survival (PFS). Univariate and multivariate Cox proportional hazard models were conducted to identify the prognostic factors of OS and PFS before and after propensity score matching (PSM).ResultsEnrolled patients were allocated into two groups according to the presence or absence of MetS (n=84 MetS vs n=251 non-MetS), and 82 new matched pairs were identified to balance the baseline characteristics after 1:1 PSM. In the Kaplan-Meier analysis, MetS was associated with better OS (P=0.031) than the group without MetS. In addition, a body mass index (BMI) ≥ 25 was associated with better OS (P=0.011) and PFS (P=0.031), while low high-density lipoprotein cholesterol (HDL-C) was associated with worse OS (P=0.033) and PFS (P=0.010). In all patients, multivariate Cox analysis showed that hemoglobin, pathologic tumor stage and lymph node status were identified as independent prognostic factors for both OS and PFS, while age, MetS and HDL-C were independent prognostic factors only for OS. Reproducible results of multivariate analysis can still be observed in propensity matched patients. The results of further subgroup analysis revealed that the association of MetS with increased OS (P=0.043) and BMI ≥25 with increased OS (P=0.015) and PFS (P=0.029) was observed in non-muscle invasive bladder cancer (NMIBC) patients.ConclusionsMetS was independently associated with better OS in BCa patients after RC, and HDL-C was the only component of MetS that was independently associated with worse OS. MetS and HDL-C may become reliable prognostic biomarkers of OS in BCa patients after RC to provide individualized prognostication and assist in the formulation of clinical treatment strategies.
