Robot-assisted laparoscopy repair of uterine isthmocele: A two-center observational study
Claire Cardaillac, Caroline Salmon, Vincent Lavoue
To analyze outcomes and postoperative complications in patients undergoing robot-assisted isthmocele repair.
Method
This retrospective cohort study included 33 patients who had robot-assisted laparoscopic surgical management of an isthmocele between September 2013 and August 2020 in two French university hospitals. All charts were reviewed to identify patient characteristics, preoperative and postoperative anatomical findings, complications, and postoperative fertility and symptoms. Patients who had undergone this procedure were asked to complete a telephone questionnaire about their treatment satisfaction and symptoms.
Results
The isthmocele was discovered most often as a result of subfertility (57.6%), but also ectopic pregnancy (18.2%), pelvic pain (15.2%), and postmenstrual bleeding (9.1%). Robot-assisted repair of the isthmocele significantly improved myometrial thickness (from 1.55 mm before surgery to 4.26 mm after surgery [mean difference 2.71; 95% confidence interval, 1.91-3.51], P = 0.0005). Among 20 patients who still desired a child after surgery, 15 became pregnant and 14 had full-term live births. Among the nine patients who had surgery for disabling symptoms, five had no persistent symptoms, three reported global improvement, and one had the same gynecologic discomfort. Seventeen patients agreed to complete the questionnaires (51.5%), and all stated that they would choose to have this surgery again.
Conclusion
Robot-assisted repair of an isthmocele is a viable minimally invasive procedure.

To evaluate the clinical outcomes of laparoscopic and hysteroscopic surgical approaches for treating symptomatic isthmocele and identify their associated factors. Forty-six patients with symptomatic isthmocele diagnosed using transvaginal saline infusion sonohysterography were enrolled in this prospective cohort study. Patients underwent either laparoscopic or hysteroscopic isthmoplasty based on their residual myometrial thicknesses and fertility desires and were subsequently followed by clinical and ultrasonographic examinations. Twenty-two patients underwent laparoscopy and 24 underwent hysteroscopic surgery. At baseline, there was no significant difference in the mean age and years since the last cesarean section between the two groups. However, the hysteroscopy group had a higher mean parity and previous cesarean sections (p=0.00, 0.03). The most common symptoms were abnormal uterine bleeding, infertility, and dysmenorrhea. The mean baseline residual myometrial thickness was significantly higher in the laparoscopy group (p=0.00), and only laparoscopic surgery led to a significant increase in residual myometrial thickness in patients (p=0.00). Both procedures significantly reduced abnormal uterine bleeding (p=0.00), but only laparoscopy reduced infertility (p=0.00) and hysteroscopy reduced dysmenorrhea (p=0.03). Hysteroscopy showed better symptom resolution in younger patients (p=0.01), whereas age did not affect laparoscopy outcomes. Both approaches showed similar effectiveness in resolving abnormal uterine bleeding, with laparoscopy excelling in infertility resolution and hysteroscopy excelling in dysmenorrhea resolution. AMAÇ: Bu çalışmanın amacı semptomatik istmosel tedavisinde laparoskopik ve histeroskopik cerrahi yaklaşımların klinik sonuçlarını değerlendirmek ve ilişkili faktörleri belirlemektir. GEREÇ VE YÖNTEMLER: Bu prospektif kohort çalışmasına transvajinal salin infüzyon sonohisterografi kullanılarak semptomatik istmosel tanısı konan 46 hasta dahil edildi. Hastalara rezidüel miyometrial kalınlık ve doğurganlık isteklerine göre laparoskopik veya histeroskopik istmoplasti uygulandı ve ardından hastalar klinik ve ultrasonografik muayenelerle takip edildi. Yirmi iki hastaya laparoskopi, yirmi dört hastaya ise histeroskopik cerrahi uygulandı. Başlangıçta, iki grup arasında ortalama yaş ve son sezaryenden bu yana geçen yıllar açısından anlamlı bir fark yoktu. Ancak histeroskopi grubunda ortalama parite ve önceki sezaryenlerin sayısı daha yüksekti (p=0,00, 0,03). En sık görülen semptomlar anormal uterin kanama, kısırlık ve dismenore idi. Başlangıçtaki ortalama rezidüel miyometrial kalınlık laparoskopi grubunda anlamlı derecede yüksekti (p=0,00) ve yalnızca laparoskopik cerrahi hastalarda anlamlı rezidüel miyometrial kalınlık artışına yol açtı (p=0,00). Her iki prosedür de anormal uterin kanamayı önemli ölçüde azalttı (p=0,00), ancak yalnızca laparoskopi kısırlığı azalttı (p=0,00) ve histeroskopi dismenoreyi azalttı (p=0,03). Histeroskopi genç hastalarda semptomlarda daha fazla düzelme sağladı (p=0,01), yaş ise laparoskopi sonuçlarını etkilemedi. SONUÇ: Her iki yaklaşım da anormal uterin kanamanın çözümünde benzer etkinlik göstermiştir; laparoskopi kısırlığın çözümünde ve histeroskopi dismenorenin çözümünde üstündür.
Isthmocele is a gynecological condition characterized by a disruption in the uterine scar, often associated with prior cesarean sections. This anatomical anomaly can be attributed to inadequate or insufficient healing of the uterine wall following a cesarean incision. It appears that isthmocele may impact a woman's quality of life as well as her reproductive capacity. The incidence of isthmocele can range from 20% to 70% in women who have undergone a cesarean section. This review aims to sum up the current knowledge about the effect of isthmocele on fertility and the possible therapeutic strategies to achieve pregnancy. However, currently, there is not sufficiently robust evidence to indicate the need for surgical correction in all asymptomatic patients seeking fertility. In cases where surgical correction of isthmocele is deemed necessary, it is advisable to evaluate residual myometrial thickness (RMT). For patients with RMT >2.5-3 mm, hysteroscopy appears to be the technique of choice. In cases where the residual tissue is lower, recourse to laparotomic, laparoscopic, or vaginal approaches is warranted.
To evaluate the efficacy of surgical management for isthmoceles in patients presenting with secondary infertility. Data Sources: A systematic search was performed in MEDLINE, EMBASE, and Cochrane Library databases from inception to May 2020. The search was limited to studies published in English. METHODS OF Study Selection: After the removal of duplicates, 3380 articles were screened for inclusion independently by 2 authors. These 2 authors assessed for studies which focused on women of reproductive age with a diagnosed isthmocele and secondary infertility who underwent any surgical intervention for defect repair with at least 1 of the goals being fertility restoration. TABULATION, INTEGRATION, A total of 13 studies, comprising of 1 randomized controlled trial, 6 prospective case series, and 6 retrospective case series describing 234 patients who underwent surgical management for an isthmocele and secondary infertility were included. The methodologic quality of the included studies was assessed independently by both reviewers. Next, the data extraction was performed independently and then compared to ensure no discrepancies. A total of 188 patients were treated by hysteroscopy, 36 by laparoscopy, 7 by laparotomy, and 3 through a vaginal approach. In total, 153 of the 234 patients (65.4%) achieved pregnancy across all studies within their respective study periods. Pregnancy rates in the randomized controlled trial were 21 of 28 (75%) for those treated by hysteroscopy compared with 9 of 28 (32%) for those untreated. Among the studies reporting pregnancy outcomes, 101 of 116 (87.1%) pregnancies resulted in a live birth. The incidence of adverse events was 2%, including the risk of reoperation. The results of this systematic review suggest that the surgical treatment of an isthmocele, particularly through hysteroscopy, in patients with residual myometrial thickness of at least 2.5 mm, may be effective in treating isthmocele-associated secondary infertility with a relatively low complication rate. Further high-quality studies are needed because of the small sample sizes and observational nature of most available data.
The objective of this study was to evaluate the prevalence of cesarean scar defects and its clinical manifestations in reproductive-aged women. We performed a systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement using keywords of "cesarean scar defect, uterine scar defect, uterine diverticulum niche, isthmocele, pouch, or sacculation" and their combination. Thirty-two trials met the inclusion criteria. Cesarean scar defects are commonly found on ultrasound examination (24%-88%). Their presence could be asymptomatic or related to postmenstrual spotting, postmenstrual bleeding, or infertility. The prevalence of this condition is related to the number of cesarean deliveries. Hysteroscopic repair of a cesarean scar defect or isthmoplasty is associated with an improvement in uterine bleeding in 59% to 100% of cases and a pregnancy rate of 77.8% to 100%. An improvement in uterine bleeding after vaginal repair occurred in 89% to 93.5% of cases. Laparoscopic repair led to uterine bleeding improvement in 86% of cases and a pregnancy rate of 86%. The association between cesarean scar defect and infertility, pelvic pain, and dysmenorrhea require more studies. Treatment of uterine scar defects should be performed after eliminating other causes of postmenstrual bleeding or infertility. Hysteroscopic isthmoplasty appears to be the most popular treatment. However, in the absence of randomized trials, the efficacy of different surgical approaches remains to be seen. Until we have concrete evidence, the treatment should be reserved for selective cases.
