The Importance of Isthmocele Development Due to Primary Cesarean Section at The Latent or Active Phase of Labour

The dates between February 2021 to December 2021 , primiparous (primigravida) and multiparous (multigravida) patients who were hospitalized for delivery between 32 and 41 weeks of gestation and who haven't received cesarean in their previous delivery will be included in the study in Zeynep Kamil Training and Research Hospital Hynecology and Obstetrics Clinic. These patients who will have indication for primary cesarean section will be divided into two groups as latent and active phase according to cervical opening and effacement.During cesarean section , tue uterine lower segment transverse incision will be continuously sutured with 1.0 vicryl( with no interlocking). Also the visceral peritoneum of the vesicle-uterine cavity will be sutured with 2.0 vicryl, This closure technique is to provide hemostasis in the incision. Also additional single interrupted sutures will be recorded(on the each side and /or in the middle of incision).Also If additional surgical interventions such as vessel ligation, uterine artery compression sutures ( such as B-Lynch) will be performed during the surgery, the will be recorded.In this study, If the patients with gestational age below 32, confirmed placenta previa or invasion anomaly and a history of previous cesarean section will not be included.All patient's age, gravid , parity, height, weight, gestational week, smoking history, chronic disease such as hypertension, diabetes mellitus, obstetric history such as oligo-polihidroamnios, abortus imminent,etc previous abdominal surgeries, drug use, use of dinoprost(process) for cervical effacement, cervical Foley catheter use, use of oxytocin, duration of labor, presence of early membrane rupture, time interval from the beginning of rupture membrane, presentation, indication for cesarean section, cervikal dilatation and effacement just before the cesarean section, duration of the operation, use of additional uterotonics during the surgery, additional sutures for hemostasis, presence of atony, additional surgical interventions( uterine artery and hypogastric artery ligation, uterine compression sutures), birth weight, preoperative and post hemogram, hematocrit, white blood cell count, platelet count, blood transfusion if it was given, discharge time, and endometriosis will be recorded. Patients will be called for control examination in the third( 3rd) month after operation. And patients will be asked about clinical findings such as prolonged menstrual bleeding, midsiklus bleeding, dysmenorrhea, pelvic pain. At the same time the presence of isthmuses, the depth and the shape of the istmosel pocket and the myometrial thickness will be measured and recorded with transvaginal ultrasound. Thus, the importance of isthmocele formation on patients who had caeserean section either on latent phase or active phase of labor will be investigated . In addition , other risk factors leading to isthmocele formation will be investigated.
