Does preoperative resting genital hiatus size predict surgical outcomes?

AIM: To determine whether preoperative genital hiatus at rest is predictive of medium-term prolapse recurrence. METHODS: We conducted a retrospective study of women who underwent native tissue prolapse surgery from 2002 to 2017 with pelvic organ prolapse quantification data including resting genital hiatus at one of three time points: preoperatively, 6 weeks, and ≥1 year postoperatively. Demographics and clinical data were abstracted from the chart. Prolapse recurrence was defined by anatomic outcomes (Ba > 0, Bp > 0, and/or C ≥ -4) or retreatment. Descriptive statistics, bivariate analyses, and logistic regression analyses were performed. RESULTS: Of the 165 women included, 36 (21.8%) had prolapse recurrence at an average of 1.5 years after surgery. Preoperative resting genital hiatus did not differ between women with surgical success versus recurrence (3.5 cm [interquartile range, IQR 2.25, 4.0) vs 3.5 cm (IQR 3.0, 4.0), p = 0.71). Point Bp was greater in the recurrence group at every time point. Preoperative Bp (odds ratio [OR] 1.24, confidence interval [CI] [1.06-1.45], p = 0.01) and days from surgery (OR 1.001, CI [1.000-1.001], p < 0.01) were independently associated with recurrence. Preoperative genital hiatus at rest and strain were significantly larger among women who underwent a colpoperineorrhaphy (rest: 4.0 [3.0, 4.5] cm vs 3.5 [3.0, 4.0] cm, p < 0.01; strain: 6.0 [4.0, 6.5] cm vs 5.0 [4.0, 6.0] cm, p = 0.01). CONCLUSIONS: Preoperative genital hiatus at rest was not associated with prolapse recurrence when the majority of women underwent colpoperineorrhaphy. Preoperative Bp was more predictive of short-term prolapse recurrence. For every 1 cm increase in point Bp, there is a 24% increased odds of recurrence.

Introducción: Analizar los resultados a corto y mediano plazo del tratamiento del rectocele anterior mediante la resección rectal transperineal con engrapadora lineal y refuerzo del tabique rectovaginal con malla. Prospectivo de casos consecutivos. Pacientes y método: Entre 01 de abril de 2008 y 31 de Marzo de 2010, 12 pacientes fueron tratados en nuestra institución por presentar diagnóstico de Rectocele Anterior. Los pacientes fueron evaluados por cirujanos entrenados; sometidos a manometría anorrectal y estudios imagenológicos dinámicos. Se realizó una técnica de Resección Rectal por vía perineal con engrapadora lineal y la aplicación de malla. Se aplicaron distintos scores para evaluar los resultados. Resultados: El 100% fueron sexo femenino, edad promedio 44,6 años. El tiempo promedio de cirugía fue 164 minutos (r: 135-180). No hubo complicaciones intraoperatorias. La estadía media hospitalaria fue 2,6 días. La morbilidad fue del 16,6% (2) y no hubo mortalidad relacionada al procedimiento. La evaluación basal del score ODS mostró un promedio de 19.16, mientras el promedio determinado al 7 y 21 día postoperatorio fue 0,5 y 0,16 respectivamente (P = 0,001). La evaluación del estreñimiento usando el score PAC-SYM mostró un resultado basal promedio de 17,08, mientras que al 7 y 21 día postoperatorio fue 3,25 y 1,32 respectivamente (P = 0,002). El cuestionario de Satisfacción a los 6 meses mostró mejoría significativa respecto al valor basal (p = 0,001). Conclusión: Esta nueva técnica permite restaurar el tabique rectovaginal resecando el defecto rectal. Los resultados funcionales obtenidos son favorables, con baja morbilidad y pocas complicaciones relacionadas al uso de mallas. (AU)

Objective: To analyze short and mid-term results of anterior rectocele treatment by trans perineal rectal resection with linear stapler and rectovaginal septum reinforcement with mesh. Patients and methods: Between 01April 2008 and 31 March 2010, 12 patients were treated at our institution with diagnosis of Anterior Rectocele. Patients were evaluated by trained surgeons, underwent anorectal manometry and dynamic images studies. We performed a novel technique called "Stapled Perineal Rectocele resection". Different scores were applied to evaluate the results. Results: 100% were female, average age 44.6 years. The mean surgical time was 164 minutes (r: 135-180). There were no intraoperative complications. The average hospital stay was 2.6 days. The morbidity was 16.6% (2) and there was no procedure-related mortality. Baseline of ODS showed an average score of 19.16, while the average determined at 7 and 21 days postoperatively was 0.5 and 0.16 respectively (P = 0.001). The assessment of constipation using the PAC-SYM score showed a mean baseline of 17.08 results, while at 7 and 21 days after surgery was 3.25 and 1.32 respectively (P = 0.002). The patient satisfaction score after six months showed significant improvement from baseline (p = 0.001). Conclusion: The novel technique restores rectovaginal septum and extirpates the rectal defect. The functional results are favorable, with low morbidity and few complications related to the use of mesh. (AU)

TRREMS procedure (transanal repair of rectocele and rectal mucosectomy with one circular stapler): a prospective multicenter trial / Procedimento TRREMS (reparo transanal de retocele e mucosectomia retal com um grampeador circular): estudo multicêntrico prospectivo

CONTEXT: Since anorectocele is usually associated with mucosa prolapse and/or rectal intussusceptions, it was developed a stapled surgical technique using one circular stapler. OBJECTIVE: To report the results of Transanal Repair of Rectocele and Rectal Mucosectomy with one Circular Stapler (TRREMS procedure) in the treatment of anorectocele with mucosa prolapse in a prospective multicenter trial. METHODS: It was conducted by 14 surgeons and included 75 female patients, mean aged 49.6 years, with symptoms of obstructed defecation due to grade 2 (26.7 percent) and grade 3 (73.3 percent) anorectocele associated with mucosa prolapse and/or rectal intussusception (52.0 percent) and an average validated Wexner constipation score of 16. All patients were evaluated by a proctological examination, cinedefecography, anal manometry and colonic transit time. The TRREMS procedure consists of the manual removal of the rectocele wall with circumferential rectal mucosectomy performed with a circular stapler. The mean follow-up time was 21 months. RESULTS: All patients presented obstructed defecation and they persisted with symptoms despite conservative treatment. The mean operative time was 42 minutes. In 13 (17.3 percent) patients, bleeding from the stapled line required hemostatic suture. Stapling was incomplete in 2 (2.6 percent). Forty-nine patients (65.3 percent) required 1 hospitalization day, the remainder (34.7 percent) 2 days. Postoperatively, 3 (4.0 percent) patients complained of persistent rectal pain and 7 (9.3 percent) developed stricture on the stapled suture subsequently treated by stricturectomy under anesthesia (n = 1), endoscopic stricturectomy with hot biopsy forceps (n = 3) and digital dilatation (n = 3). Postoperative cinedefecography showed residual grade I anorectoceles in 8 (10.6 percent). The mean Wexner constipation score decreased significantly from 16 to 4 (0-4: n = 68) (6: n = 6) (7: n = 1) (P<0.0001). CONCLUSION: Current trial results suggest that TRREMS procedure is a safe and effective technique for the treatment of anorectocele associated with mucosa prolapse. The stapling technique is low-cost as requires the use of a single circular stapler.

CONTEXTO: Como a anoretocele está sempre associada a prolapso mucoso e/ou intussuscepção retal, foi desenvolvida uma técnica cirúrgica grampeada, utilizando somente um grampeador mecânico. OBJETIVO: Demonstrar os resultados do estudo multicêntrico que realizou o tratamento cirúrgico de pacientes com anorretocele associado a prolapso mucoso, utilizando o reparo transanal da retocele e mucosectomia com grampeador circular mecânico. MÉTODO: Foram incluídos 75 pacientes, média de idade 49,6 anos, com sintomas de evacuação obstruída, apresentando escore médio de constipação de Wexner de 16 e diagnóstico de anorretocele grau II (26.7 por cento), grau III (73,3 por cento) associado a prolapso mucoso e intussuscepção (52 por cento). Todos foram avaliados com exame proctológico, defecografia, manometria anorretal e tempo de trânsito colônico. O procedimento cirúrgico foi realizado por 14 cirurgiões e consiste na remoção manual da parede do reto no local da retocele e mucosectomia circunferencial com um grampeador circular mecânico. O seguimento médio foi de 21 meses. RESULTADOS: Os pacientes apresentavam sintomas de evacuação obstruída, mesmo após tratamento clinico. O tempo operatório médio foi de 42 minutos. Houve sangramento transanal na linha de sutura em 13 (17,3 por cento) pacientes, sutura grampeada incompleta em 2 (2,6 por cento) e dor retal persistente em 3 (4,0 por cento). O tempo médio de internação hospitalar foi de 1 dia em 49 (65,3 por cento) e 2 dias em 34,7 por cento. Ocorreu redução na linha de sutura em 7 (9,3 por cento), sendo necessário estricturotomia cirúrgica sob anestesia (n = 1), utilizando "hot biopsy" (n = 3) e dilatação anal (3). Defecografia no pós-operatório demonstrou anorretocele residual grau I em 8 (10.6 por cento). O escore de constipação de Wexner reduziu 16 para 4 (0-4: n = 68) (6: n = 6) (7: n = 1) (P<0.0001). CONCLUSÃO: O resultado do estudo multicêntrico demonstrou que a técnica cirúrgica apresentada é segura e efetiva para tratamento da anorretocele associada a prolapso mucoso. Apresenta baixo custo pois utiliza um grampeador circular mecânico.
