Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been established as a leading treatment of obesity. Surgical site infections (SSIs) remain the most common complication.
Objective: To compare the incidence of SSIs before and after the implementation of our technique.
Methods: Our intraoperative technique limits enteric contact with the abdominal wall through a wound protector at the end-to-end anastomosis stapler port site, with enteric retrieval with a specimen bag followed by betadine irrigation. We analyzed our SSIs outcomes before and after implementation of our technique in all RYGB and laparoscopic sleeve-to-bypass conversions at our institution performed by two providers between January 1, 2009 to December 31, 2011 and January 1, 2019 to December 31, 2021. We compared patient age, sex, body mass index, American Society of Anesthesiologists class; and comorbidities including hypertension, diabetes, and hyperlipidemia. The χ, Fischer exact, Wilcoxon Rank Sum tests, and multivariate analysis were performed.
Results: Four hundred twenty-nine patients underwent LRYGB and sleeve-to-bypass conversion during the two study periods. Group 1 (162 patients, 37.76%) all underwent RYGB. Group 2 (267 patients, 62.24%) of whom 199 underwent RYGB and 68 underwent a laparoscopic sleeve-to-bypass conversion. The SSI rate was 9.26% in Group 1 and 2.62% in Group 2 (p = 0.002514). Statistical significance was also noted for operating room time (137 min vs 123 min, p = 0.02) and hospital length of stay (2 - 3 interquartile range vs 1 - 2 interquartile range, p = 0.04).
Conclusion: We propose a safe, reproducible technique that significantly reduces SSI rates during LRYGB.

Robot-Assisted Laparoscopic Sacrohysteropexy with Autologous Fascia Lata.
Int Urogynecol J
December 2024
Department of Obstetrics and Gynaecology, Monash University, Clayton, VIC, 3168, Australia.
Introduction And Hypothesis: Autologous fascia lata has been increasingly utilised in pelvic floor reconstructive surgeries such as sacrocolpopexy and sacrohysteropexy. This case highlights sacrohysteropexy with autologous fascia lata as a promising option for women with advanced uterovaginal prolapse who wish to preserve their uterus and avoid synthetic mesh.
Methods: We report the case of a 65-year-old woman with stage 3 pelvic organ prolapse following one forceps and one spontaneous vaginal delivery.
Comparison of two strategies estimating surgically induced astigmatism in position prediction of toric IOLs in 2.2 mm cataract surgery.

Eye Institute and Department of Ophthalmology, Eye & ENT Hospital, Fudan University, No. 83 Fenyang Road, Shanghai, 200031, China.
Purpose: To compare the precision of the arithmetic mean of surgically induced astigmatism (M-SIA) and the centroid of surgically induced astigmatism (C-SIA) in estimating SIA when predicting the power and axis of toric IOLs under different circumstances.
Methods: 120 eyes of 99 patients undergoing toric IOL replacement in a simple cataract surgery were included in the retrospective study. The predicted position of toric IOL was calculated by Z Calc online calculator and Barrett Toric Calculator with M-SIA (0.
CPSF4-mediated regulation of alternative splicing of HMG20B facilitates the progression of triple-negative breast cancer.

Department of Breast Surgery, College of Medicine, The First Affiliated Hospital, Zhejiang University, Hangzhou, 310000, Zhejiang, China.
Background: Aberrant alternative splicing (AS) contributes to tumor progression. A crucial component of AS is cleavage and polyadenylation specificity factor 4 (CPSF4). It remains unclear whether CPSF4 plays a role in triple-negative breast cancer (TNBC) progression through AS regulation.

Department of Orthopedics & Elderly Spinal Surgery, National Clinical Research Center for Geriatric Diseases, Xuanwu Hospital of Capital Medical University, Beijing, China.
Objective: To specifically evaluate the safety and benefit of different drainage removal criteria (50 ml and 100 ml per 24 h) in patients undergoing short-level lumbar fusion surgery.
Methods: Patients with degenerative lumbar diseases who underwent short level lumbar fusion with instrumentation between January 2021 and January 2023 were retrospectively recruited in the study. Based on the different criteria for drainage removal, the patients were divided into 2 groups (group A and group B).
