ABSTRACT

Background: Cesarean section (CS) is the most common operation in obstetrics. As a result of cesarean scar dehiscence may occur, which may lead to uterine rupture in a subsequent pregnancy.

Objective: To assess the frequency of uterine scar dehiscence on repeat cesarean section at term after trial of labor among patients with previous Cesarean section and to determine the frequency of various contributing factors of uterus scar dehiscence on repeat CS after trial of labor.

Methodology: This Descriptive case series was conducted for 6months. 180 females with previous one CS undergoing trial of labor were included through non-probability purposive sampling. All the patients who went through the cesarean section and scar dehiscence were observed at the time of operation. All the information was collected on a specially designed proforma. Contributing factors were assessed in all patients who showed scar dehiscence per-operatively.

Results: The mean age of patients was 30.03±5.25 years. The mean gestational age of females at time of delivery was 38.04±0.79 weeks. In 21 (12%) females scar dehiscence was observed. There was no significant effect of age and gestational age. In 21 cases of scar dehiscence, prolonged 2nd stage of labor was observed in 14 (67%) cases, short interpregnancy interval (<18 months) in 7 (33%) cases and hypertension in 5 (24%) cases.

Conclusion: It was concluded through results of this study that scar dehiscence was present in few cases but not negligible and can be modified by modifiable factors.
