[Effect of laparoscopic modified with two different sutures on cesarean section incision]

Objective: To investigate the effect of laparoscopic modified with two different sutures on the cesarean incision diverticulum repair. Methods: From July 2018 to July 2019, 35 patients with refertility requirements who were confirmed the diagnosis of caesarean incision diverticulum by hysteroscopy combined with ultrasound, and the muscle layer thickness at the top of diverticulum was less than 3 mm, received modified laparoscopic combined with hysteroscopic surgery in department of gynecological minimally invasive center, Beijing Obstetrics and Gynecology Hospital, Capital Medical University. Ten patients with history of secondary repair and multiple pelvic operations were excluded. The remaining 25 patients were divided into group A (n=8): underwent laparoscopic "folding suture" , preserving the integrity of the diverticulum of the cesarean incision; Group B (n=17): underwent laparoscopic incision and complete excision of the scar of the diverticulum. The operation time, bleeding volume, postoperative exhaust time, improvement of symptoms and the thickness of muscle layer were compared between the two groups. Results: All patients underwent surgery without complications. 25 patients were followed up one month, three months and half a year after operation, and followed up by telephone for 6-18 months. The operation time of group A and B was (56±12) min, (72±15) min, and the bleeding volume was (40±9) ml and (66±10) ml respectively. The cure rate was 87.5% and 58.8% respectively, the differences were statistically significant (t=6.778, 4.057, χ(2)=5.651, P<0.05). But the postoperative exhaust time was (16±6) h, (18±7) h, and the effective rate was 100.0% and 94.1% respectively, with no significant difference(t=1.967, χ(2)=0.725, P>0.05). Conclusion: Two different suture repair methods under laparoscope are safe and effective for the treatment of diverticulum in cesarean section incision. Among them, the laparoscopic "folding suture" method has a short operation time and preserves the integrity of the myometrium. It is worth popularizing for the elderly patients who has an urgent need for fertility.
