Laparoscopic Isthmocele Repair

Официальное название

Efficacy and Safety of V-LocTM 180 Barbed Sutures Compared to Polyglactin 910 Vicryl in Laparoscopic Isthmocele Repair: A Prospective Randomized Study

Обзор

To evaluate postoperative outcomes in patients with isthmocele undergoing laparoscopic repair, comparing the efficacy of V-LocTM 180 and Polyglactin 910 Vicryl sutures. Patients were randomized to undergo laparoscopic isthmocele repair using one of the following suture materials: (1) V-LocTM 180 or (2) Polyglactin 910 Vicryl.

Подробное описание

The global rise in cesarean section (CS) rates has led to an increased incidence of associated complications, presenting new challenges in gynecological practice. One of these complications is a cesarean scar defect, also known as isthmocele, which manifests as a pouch-like structure at the site of the previous CS scar. This defect often results in the accumulation of menstrual blood, inflammatory cells, and mucus, leading to symptoms such as postmenstrual bleeding, pelvic pain, and dyspareunia. Furthermore, isthmocele has been implicated in secondary infertility due to the inflammatory changes it induces in the endometrium. Additionally, the presence of an isthmocele increases the risk of complications in future pregnancies, including cesarean scar ectopic pregnancy, uterine rupture, and placenta accreta spectrum disorders.

Diagnosis of isthmocele relies on imaging modalities such as transvaginal ultrasound (TVUS), sonohysterography (SHG), or hysteroscopy. While asymptomatic cases generally do not require intervention, symptomatic patients may benefit from medical or surgical treatment. Due to limited evidence supporting medical therapy, surgical intervention has become the preferred approach, particularly for patients desiring future fertility. Various surgical techniques, including hysteroscopic, laparoscopic, vaginal, laparotomic, and combined procedures, have been proposed for isthmocele repair. Among these, laparoscopic isthmocele repair is favored for patients with fertility concerns as it enables complete excision of the defective myometrial tissue and reconstruction of the uterine wall.

Despite the advantages of laparoscopic isthmocele repair, no universally accepted cutoff value for residual myometrial thickness dictates surgical candidacy. Previous studies have suggested that laparoscopic repair is a safer and more practical option for cases with significant myometrial loss (\>80%). However, there is limited data on the impact of different suture materials used in laparoscopic repair on postoperative outcomes.

  The standardized surgical steps for the laparoscopic isthmocele repair were as follows; 1) A 30-degree telescope was introduced through a 10 mm trocar at the umbilicus following the establishment of pneumoperitoneum. 2) Three 5 mm trocars were inserted: two in the bilateral lower quadrants and one in the suprapubic region. 3) The bladder was distended with 300 cc of saline infusion to facilitate dissection of the vesicovaginal space and to allow inferior mobilization of the bladder, thereby ensu
