Objective: To demonstrate the surgical technique of Rendez-vous isthmoplasty for the treatment of symptomatic cesarean scar defect. In this video, the authors show the complete procedure in a step-by-step manner to standardize and facilitate the comprehension and performance of the procedure in a simple and safe way.
Design:Step-by-step video demonstration of the surgical technique. Setting: Private hospital in Curitiba, Paran a, Brazil. Interventions: The patient is a 36-year-old woman without any comorbidities, G3 C3, and with radiologic transvaginal ultrasound diagnosis of isthmocele grade 3 (over 25 mm) identified in the superior third of the cervical canal. The main steps of combined laparoscopic-hysteroscopic isthmoplasty using the Rendez-vous technique are described in detail. A combined laparoscopic-hysteroscopic approach was performed. Under general anesthesia, the patient was placed in 0˚supine decubitus, with her arms alongside her body. Operative setup included 15 mm Hg pneumoperitoneum, created using the closed Veress technique, and 4 trocars: a 10-mm trocar at the umbilicus for a 0˚laparoscope, a 5-mm trocar in the right iliac fossa, a 5-mm trocar in the left iliac fossa, and a 5-mm trocar in the suprapubic area. The procedure begins after a systematic exploration of the pelvic and abdominal cavities.Step 1: Identification of key anatomic landmarks and exposure of the operation field.Step 2: By carrying out blunt and sharp dissection with cold scissors or a harmonic scalpel, the visceral peritoneal layer over the isthmus area is opened, a vesicouterine space is developed, and the bladder is pushed down at least 2 cm from the lower edge of the isthmocele.Step 3: Final Phrase: By hysteroscopic exploration of the cervical canal using the vaginoscopic approach, identification and delimitation of the isthmocele its performed by recognizing the diverticular mucosal hyperplasia, and then the hysteroscopic light is pointed directly toward the cephalic limit of the scar defect.Step 4: Laparoscopic lights are decreased in intensity and the "Halloween sign" is identified (hysteroscopic transillumination). The light of the hysteroscope is pointed to the top of the cesarean scar defect allowing the laparoscopist to identify the upper and lower edges of the scar.Step 5: Laparoscopic resection of all scar tissue, excision of all the edges of the pseudo cavity.Step 6: Adequate intracorporeal suturing technique, with a 2-layer myometrial repair using intracorporeal running and interrupted stitches of polydioxanone 2-0, is done, while ensuring preservation of the cavity by not including the endometrial tissue in the myometrial suture [1−3].Step 7: Installation of the methylene blue dye to locate any leakage. The surgery ended without any intraoperative complications and within 60 minutes. The patient was discharged on the first day postoperatively and became pregnant 6 months after surgery, with a final C-section delivery of a healthy term newborn at 39-weeks gestational age. Conclusion: Combined Rendez-vous isthmopl...
To demonstrate the application of the so-called reverse technique to approach deep infiltrating endometriosis nodules affecting the retrocervical area, the posterior vaginal fornix, and the anterior rectal wall. In Video 1, the authors describe the complete procedure in 10 steps in order to standardize it and facilitate the comprehension and the reproduction of such a procedure in a simple and safe way. Design: A case report. Setting: A private hospital in Curitiba, Paran a, Brazil. Patient: A 32-year-old woman was referred to our service complaining about cyclic dysmenorrhea, dyspareunia, chronic pelvic pain, and cyclic dyschezia. Transvaginal ultrasound with bowel preparation showed a 2.4-cm endometriotic nodule at the retrocervical area, uterosacral ligaments, posterior vaginal fornix, and anterior rectal wall, infiltrating up to the muscularis 10 cm far from the anal verge. Interventions: Not applicable. Measurements and Main Results: Under general anesthesia, the patient was placed in the dorsal decubitus position with her arms alongside her body and her lower limbs in abduction. Pneumoperitoneum was achieved using a Veress needle placed at the umbilicus. Four trocars were placed according to the French technique as follows: a 10-mm trocar at the umbilicus for the 0 degree laparoscope; a 5-mm trocar at the right anterosuperior iliac spine; a 5-mm trocar in the midline between the umbilicus and the pubic symphysis, approximately 8 to 10 cm inferior to the umbilical trocar; and a 5-mm trocar at the left anterosuperior iliac spine. The entire pelvis was inspected for endometriotic lesions (step 1). The implants located at the ovarian fossae were completely removed (step 2). The ureters were identified bilaterally, and both pararectal fossae were dissected, preserving the hypogastric nerves (step 3). The lesion was separated from the retrocervical area, and the posterior vaginal fornix was resected (reverse technique), leaving the disease attached to the anterior surface of the rectum (step 4). The lesion was shaved off the anterior rectal wall using a harmonic scalpel (step 5). The anterior rectal wall was closed using X-shaped stitches of 3-0 polydioxanone suture in 2 layers (step 6). The specimen was extracted through the vagina (step 7). The posterior vaginal fornix was reattached to the retrocervical area using X-shaped sutures of 0 poliglecaprone 25 (step 8). A pneumatic test was performed to check the integrity of the suture (step 9). At the end of the procedure, hemostasis was controlled, and the abdominal cavity was irrigated using Lactate ringer solution (step10).
Conclusion:The laparoscopic reverse technique is an alternative approach to face retrocervical or rectovaginal nodules infiltrating the anterior rectal wall. In this technique, the separation of the nodule from the rectal wall is performed at the end of the surgery and not at the beginning as performed within the traditional technique. This enables the surgeon to perform a more precise dissection of the endometriotic nodule from the rectal wa...
This review summarizes the evidence-based recommendations for how to approach and laparoscopically treat adnexal masses during pregnancy. We conducted a comprehensive review of studies related to the laparoscopic management of adnexal masses during pregnancy. Selected studies were independently reviewed by two authors. The overall incidence of ovarian tumors in pregnancy ranges between 0.05% and 5.7%, of which less than 5% are malignant. Diagnosis is based mainly on routine transvaginal ultrasound. More than 64% of simple cysts, less than 6 cm in diameter, will spontaneously resolve in less than 16 weeks. However, for persistent and complex tumors, the risk of acute complications can reach up to 9%. Surgical indications are similar to those in the non-gravidic setting, and include acute complications (torsion, rupture, hemorrhage), suspected malignancy and large (over 6 cm) persistent masses. Surgery must be scheduled between 16 and 20 weeks to allow for the spontaneous resolution of functional cysts. Furthermore, within that period, pregnancy becomes independent of the corpus luteum and enlargement of the uterus gives sufficient exposure for the surgery to be performed safely. A recent meta-analysis found that, compared to open surgery, laparoscopy is associated with significantly less preterm labor, blood loss and hospital stay, without differences in pregnancy loss or preterm birth rate. Since the main concerns about maternal-fetal safety are related to increased intraperitoneal pressure and the effects of hypercarbia (maternal hypertensive complications, fetal acidosis), a lower CO2 pressure (10 to 12 mmHg) and reduced operative times (less than 30 minutes) are recommended.
