Effect of avoiding bladder flap formation in caesarean section on repeat caesarean delivery

Area of Science:

• Reproductive Medicine
• Surgical Pathology
• Obstetrics and Gynecology

Background:

• Caesarean section (CS) is a common surgical procedure.
• Uterine scar quality is crucial for subsequent pregnancies.
• Bladder flap formation (BFF) is a surgical technique sometimes employed during CS.

Purpose of the Study:

• To investigate the impact of bladder flap formation (BFF) during caesarean section (CS) on the uterine scar.
• To assess histological changes in uterine scars at repeat CS.

Main Methods:

• A prospective study involving 115 women undergoing their first CS.
• Women were divided into two groups: CS with BFF (n=58) and CS without BFF (n=57).
• Uterine scar specimens were collected during repeat CS and analyzed using light microscopy and transmission electron microscopy (TEM).

Main Results:

• Higher rates of adhesions were observed in the BFF group (48.3%) compared to the non-BFF group (24.1%).
• Significant differences in submesothelial fibrosis and neo-angiogenesis were noted between groups.
• TEM revealed increased inflammatory cells in scars from women who had BFF during their initial CS.

Conclusions:

• Bladder flap formation during CS is associated with increased inflammation and fibrosis of the uterine scar.
• CS performed without BFF demonstrates reduced inflammatory processes and fewer intraperitoneal adhesions.
• Avoiding BFF may improve uterine scar quality and reduce complications in subsequent pregnancies.
