RESUMO

BACKGROUND: Surgical treatment of recurrent rectal prolapse is associated with unique technical challenges, partially determined by the surgical approach used for the index operation. Success rates are variable, and data to determine the best approach in patients with recurring prolapse are lacking. OBJECTIVE: The study aimed to assess current surgical approaches to patients with prior rectal prolapse repairs and to compare short-term outcomes of de novo and redo procedures, including recurrence of rectal prolapse. DESIGN: Retrospective analysis of a prospective database. SETTINGS: The Multicenter Pelvic Floor Disorders Consortium Prospective Quality Improvement database. De-identified surgeons at more than 25 sites (81% high volume) self-reported patient demographics, prior repairs, symptoms of incontinence and obstructed defecation, and operative details, including history of concomitant repairs and prior prolapse repairs. PATIENTS: Patients who were offered surgery for full thickness rectal prolapse. INTERVENTIONS: Incidence and type of repair used for prior rectal prolapse surgery were recorded. Primary and secondary outcomes of index and redo operations were calculated. Patients undergoing rectal prolapse re-repair (redo) were compared with patients undergoing first (de novo) rectal prolapse repair. The incidence of rectal prolapse recurrence in de novo and redo operations was quantified. OUTCOMES: The primary outcome of rectal prolapse recurrence in de novo and redo settings. RESULTS: Eighty-nine (19.3%) of 461 patients underwent redo rectal prolapse repair. On short-term follow-up, redo patients had prolapse recurrence rates similar to those undergoing de novo repair. However, patients undergoing redo procedures rarely had the same operation as their index procedure. LIMITATIONS: Self-reported, de-identified data. CONCLUSION: Our results suggest that recurrent rectal prolapse surgery is feasible and can offer adequate rates of rectal prolapse durability in the short term but may argue for a change in surgical approach for redo procedures when clinically feasible.

RESUMO

BACKGROUND: Pelvic organ prolapse is reported in 30% of women presenting with rectal prolapse. Combined repair is a viable option to avoid the need for future pelvic floor interventions. However, the added impact of adding a modicum of middle compartment suspension by closing the pouch of Douglas during a rectal prolapse repair has not been studied. OBJECTIVE: The study aimed to assess the impact of middle compartment suspension on the durability of rectal prolapse repair. We also aimed to determine whether adding some form of pouch of Douglas closure to achieve middle compartment suspension leads to any improvements in the rates or severity of postoperative constipation or in the rates or severity of postoperative fecal incontinence. DESIGN: This study was a retrospective analysis of a multicenter prospective database. SETTING: Data were analyzed from the Pelvic Floor Disorders Consortium Quality Improvement in Rectal Prolapse Surgery database. Deidentified surgeons at more than 20 sites (75% academic, 81% high volume) self-reported patient demographics, previous repairs, symptoms of fecal incontinence and obstructed defecation, and operative details, including addition of concomitant gynecologic repairs, use of mesh, posterior or ventral dissection, and sigmoidectomy. PATIENTS: Patients were included who underwent abdominal repair for rectal prolapse. INTERVENTIONS: Abdominal rectopexy procedures with and without middle compartment suspension were compared. Middle compartment suspension was defined as excision and closure of the pouch of Douglas with some degree of colpopexy or culdoplasty. MAIN OUTCOME MEASURES: The primary outcome of prolapse recurrence and secondary outcomes of incontinence and constipation were calculated via univariate and multivariable regression by comparing those who underwent rectopexy with and without middle compartment suspension. RESULTS: Of the 198 patients (98% female, age 60.2 ± 15.6 years) who underwent abdominal repairs (59% robotic), 138 patients (70%) underwent some concomitant middle compartment suspension. Patients who had an added middle compartment suspension seemed to have lower early rectal prolapse recurrences. On multivariable regression to control for age, previous repairs, and the use of mesh, addition of some form of pouch of Douglas repair was associated with a decrease in short-term recurrences. LIMITATIONS: Our data need to be interpreted cautiously. Future studies are critically needed to further explore this observation, with an a priori, prospective definition of middle compartment suspension, validated measurement of concomitant pathology, and longer follow-up. CONCLUSION: Our results suggest that some middle compartment suspension at the time of rectal prolapse repair may improve short-term durability of rectal prolapse repair.

Quisimos de igual manera determinar si el agregado de algún tipo de cierre del fondo de saco de Douglas para lograr la suspensión del compartimento medio conduce a alguna mejora en las tasas o la gravedad del estreñimiento posoperatorio así como en las tasas o la gravedad de la incontinencia fecal posoperatoria.DISEÑO:Análisis retrospectivo de una base de datos prospectiva.ESCENARIO:Base de datos Multicenter Pelvic Floor Disorders Consortium Prospective Quality Improvement.

Los pacientes a los que se les añadió una suspensión del compartimento medio parecían tener menores recurrencias tempranas del prolapso rectal y, en la regresión multivariable para controlar la edad, las reparaciones previas y el uso de malla, la adición de alguna forma de reparación del fondo de saco de Douglas se asoció con una disminución de las recurrencias a corto plazo.LIMITACIONES:Nuestros datos deben interpretarse con cautela. Se necesitan de manera critica, estudios futuros para explorar más a fondo esta observación, con una definición prospectiva a priori de la suspensión del compartimento medio, una medición validada de la patología concomitante y un seguimiento más prolongado.CONCLUSIONES:Nuestros resultados sugieren que alguna suspensión del compartimento medio en el momento de la reparación del prolapso rectal puede mejorar la durabilidad a corto plazo de la reparación del prolapso rectal.

RESUMO

Solitary Peutz-Jeghers type polyps are characterized by a hamartomatous polyp of the gastrointestinal (GI) tract in a patient without mucocutaneous pigmentation, family history of Peutz-Jeghers syndrome, or STK11/LKB1 mutations. Histologically identical to the polyps in Peutz-Jeghers syndrome, these sporadic polyps can arise anywhere along the GI tract, with typical arborizing smooth muscles extending from the muscularis mucosa. While the lining mucosa is generally the same as the organ in which it arises, gastric pyloric and osseous metaplasia have been reported in intestinal polyps in Peutz-Jeghers syndrome. Herein, the authors report the first case of a small intestinal solitary Peutz-Jeghers type polyp with gastric antral and fundic gland lining mucosa. A 43-year-old male was admitted for small bowel obstruction. Diagnostic laparoscopy revealed jejuno-jejunal intussusception with an associated polyp measuring 7.2 cm. Histological examination showed a hamartomatous polyp with arborizing smooth muscle bundles extending from the muscularis mucosae. The polyp was lined by non-dysplastic gastric antral and fundic gland mucosa, and was sharply demarcated from the adjacent non-polypoid intestinal mucosa. Colonoscopy, esophagogastroduodenoscopy and small bowel enteroscopy revealed no additional polyps or masses. Thorough investigation of the patient's family history was negative for Peutz-Jeghers syndrome or mucocutaneous pigmentation. Molecular analysis of the lesion was negative for STK11/LKB1 mutations. A diagnosis of solitary Peutz-Jeghers type polyp of the small bowel with gastric antral and fundic gland mucosal lining was rendered.

RESUMO

BACKGROUND: The surgical management of rectal prolapse is constantly evolving, yet numerous clinical trials and meta-analyses studying operative approaches have failed to make meaningful conclusions. OBJECTIVE: The purpose of this study was to report on preliminary data captured during a large-scale quality improvement initiative to measure and improve function in patients undergoing rectal prolapse repair. DESIGN: This was a retrospective analysis of prospectively collected surgical quality improvement data. SETTINGS: This study was conducted at 14 tertiary centers specializing in pelvic floor disorders from 2017 to 2019. PATIENTS: A total of 181 consecutive patients undergoing external rectal prolapse repair were included. MAIN OUTCOME MEASURES: Preoperative and 3-month postoperative Wexner incontinence score and Altomare obstructed defecation score were measured. RESULTS: The cohort included 112 patients undergoing abdominal surgery (71 suture rectopexy/56% minimally invasive, 41 ventral rectopexy/93% minimally invasive). Those offered perineal approaches (n = 68) were older (median age, 75 vs 62 y; p < 0.01) and had more comorbidities (ASA 3-4: 51% vs 24%; p < 0.01) but also reported higher preintervention rates of fecal incontinence (Wexner 11.4 ± 6.4 vs 8.6 ± 5.8; p < 0.01). Patients undergoing perineal procedures had similar incremental improvements in function after surgery as patients undergoing abdominal repair (change in Wexner, -2.6 ± 6.4 vs -3.1 ± 5.6, p = 0.6; change in Altomare, -2.9 ± 4.6 vs -2.7 ± 4.9, p = 0.8). Similarly, patients undergoing posterior suture rectopexy and ventral mesh rectopexy had similar incremental improvements in overall scores; however, patients undergoing ventral mesh rectopexy had a higher decrease in the need to use pads after surgery. LIMITATIONS: The study was limited by its retrospective data analysis and 3-month follow-up. CONCLUSIONS: Functional outcomes improved in all of the patients undergoing prolapse surgery. Larger cohorts are necessary to show superiority among surgical procedures. Quality improvement methods may allow for systematic yet practical acquisition of information and data analysis. We call for the creation of a robust database to benefit this patient population. See Video Abstract at http://links.lww.com/DCR/B581. REPORTE PRELIMINAR DEL CONSORCIO DE TRASTORNOS DEL PISO PLVICO RECOLECCIN DE DATOS A GRAN ESCALA MEDIANTE INICIATIVAS DE MEJORAMIENTO DE LA CALIDAD PARA PROPORCIONAR INFORMACIN SOBRE LOS RESULTADOS FUNCIONALES: ANTECEDENTES:El tratamiento quirúrgico del prolapso rectal está evolucionando constantemente, sin embargo, numerosos estudios clínicos y metaanálisis que evalúan los tratamientos quirúrgicos no han logrado demostrar conclusiones significativas.OBJETIVO:Reportar datos preliminares obtenidos a gran escala durante una iniciativa de mejoramiento de la calidad para medir y mejorar la función en pacientes sometidos a reparación de prolapso rectal.DISEÑO:Análisis retrospectivo de datos recolectados prospectivamente de mejoramiento de la calidad quirúrgica.ENTORNO CLINICO:Este estudio se realizó en 14 centros terciarios especializados en trastornos del piso pélvico del 2017 al 2019.PACIENTES:Un total de 181 pacientes consecutivos sometidos a reparación de prolapso rectal externo.PRINCIPALES MEDIDAS DE VALORACION:Escala de incontinencia de Wexner y de defecación obstruida de Altomare preoperatoria y tres meses postoperatoria.RESULTADOS:El cohorte incluyó 112 pacientes sometidos a cirugía abdominal (71 rectopexia con sutura / 56% minimally invasive, 41 rectopexia ventral / 93% minimally invasive). Aquellos a los que se les realizaron abordajes perineales (n = 68) eran mayores (edad media de 75 vs. 62, p <0,01) y tenían mayorcomorbilidades (ASA 3-4: 51% vs. 24%, p <0,01), además reportaron una mayor tasa de incontinencia fecal previo a la intervención (Wexner 11,4 ± 6,4 vs. 8,6 +/- 5,8, p <0,01). Posterior a la cirugía, los pacientes sometidos a procedimientos perineales tuvieron mejoría progresiva en la función similar que los pacientes sometidos a reparación abdominal (cambio en Wexner -2,6 ± 6,4 vs. -3,1 ± 5,6, p = 0,6; cambio en Altomare -2,9 ± 4,6 vs. -2,7 ± 4,9, p = 0,8). De manera similar, los pacientes con rectopexia posterior con sutura y rectopexia ventral con malla tuvieron mejoría progresiva similares en las escalas generales; no obstante, pacientes con rectopexia ventral con malla tuvieron una mayor disminución en la necesidad de usar paños protectores después de la cirugía.LIMITACIONES:Análisis de datos retrospectivo y seguimiento de tres meses.CONCLUSIONES:Los resultados funcionales mejoraron en todos los pacientes sometidos a cirugía de prolapso. Se necesitan cohortes más grandes para demostrar superioridad entre los procedimientos quirúrgicos. Métodos de mejoramiento de la calidad pueden permitir la adquisición sistemática, pero práctica de información y análisis de datos. Hacemos un llamado para la creación de una base de datos sólida para beneficiar a esta población de pacientes. Consulte Video Resumen en http://links.lww.com/DCR/B581. (Traducción- Dr Francisco M.

RESUMO

BACKGROUND: Although interest in sphincter-sparing treatments for anal fistulas is increasing, few large prospective studies of these approaches have been conducted. OBJECTIVE: The study assessed outcomes after implantation of a synthetic bioabsorbable anal fistula plug. DESIGN: A prospective, multicenter investigation was performed. SETTING: The study was conducted at 11 colon and rectal centers. PATIENTS: Ninety-three patients (71 men; mean age, 47 years) with complex cryptoglandular transsphincteric anal fistulas were enrolled. Exclusion criteria included Crohn's disease, an active infection, a multitract fistula, and an immunocompromised status. INTERVENTION: Draining setons were used at the surgeon's discretion. Patients had follow-up evaluations at 1, 3, 6, and 12 months postoperatively. MAIN OUTCOME MEASURES: The primary end point was healing of the fistula, defined as drainage cessation plus closure of the external opening, at 6 and 12 months. Secondary end points were fecal continence, duration of drainage from the fistula, pain, and adverse events during follow-up. RESULTS: Thirteen patients were lost to follow-up and 21 were withdrawn, primarily to undergo an alternative treatment. The fistula healing rates at 6 and 12 months were 41% (95% CI, 30%-52%; total n = 74) and 49% (95% CI, 38%-61%; total n = 73). Half the patients in whom a previous treatment failed had healing. By 6 months, the mean Wexner score had improved significantly (p = 0.0003). By 12 months, 93% of patients had no or minimal pain. Adverse events included 11 infections/abscesses, 2 new fistulas, and 8 total and 5 partial plug extrusions. The fistula healed in 3 patients with a partial extrusion. LIMITATIONS: The study was nonrandomized and had relatively high rates of loss to follow-up. CONCLUSION: Implantation of a synthetic bioabsorbable fistula plug is a reasonably efficacious treatment for complex transsphincteric anal fistulas, especially given the simplicity and low morbidity of the procedure.

RESUMO

BACKGROUND: Confocal endomicroscopy has revolutionized endoscopy by offering subcellular images of the GI epithelium; however, the field of view is limited. Multiscale endoscopy platforms that use widefield imaging are needed to better direct the placement of high-resolution probes. DESIGN: Feasibility study. OBJECTIVE: This study evaluated the feasibility of a single agent, proflavine hemisulfate, as a contrast medium during both widefield and high-resolution imaging to characterize the morphologic changes associated with a variety of GI conditions. SETTING: The University of Texas MD Anderson Cancer Center, Houston, Texas, and Mount Sinai Medical Center, New York, New York. PATIENTS, INTERVENTIONS, AND MAIN OUTCOME MEASUREMENTS: Resected specimens were obtained from 15 patients undergoing EMR, esophagectomy, or colectomy. Proflavine hemisulfate, a vital fluorescent dye, was applied topically. The specimens were imaged with a widefield multispectral microscope and a high-resolution microendoscope. The images were compared with histopathologic examination. RESULTS: Widefield fluorescence imaging enhanced visualization of morphology, including the presence and spatial distribution of glands, glandular distortion, atrophy, and crowding. High-resolution imaging of widefield abnormal areas revealed that neoplastic progression corresponded to glandular heterogeneity and nuclear crowding in dysplasia, with glandular effacement in carcinoma. These widefield and high-resolution image features correlated well with the histopathologic features. LIMITATIONS: This imaging approach must be validated in vivo with a larger sample size. CONCLUSIONS: Multiscale proflavine-enhanced fluorescence imaging can delineate epithelial changes in a variety of GI conditions. Distorted glandular features seen with widefield imaging could serve as a critical bridge to high-resolution probe placement. An endoscopic platform combining the two modalities with a single vital dye may facilitate point-of-care decision making by providing real-time, in vivo diagnoses.

RESUMO

PURPOSE: This study was designed to evaluate the efficacy of the Surgisis (Anal Fistula Plug) in multiple patients at our institution and present early clinical results along with notable clinical observations from our experience. METHODS: This was a prospective analysis of all patients who received the Anal Fistula Plug for treatment of anorectal fistulas between April 2006 and February 2007. All tracts were irrigated with peroxide, the plug was inserted in the tract, and buried at the internal opening with 2-0 vicryl and mucosal advancement flap. Statistical analysis was performed with Fisher's exact test. RESULTS: Forty-five patients were treated with the Anal Fistula Plug and one patient was lost to follow-up. There were 27 males and 17 females with average age of 44.1 years treated for simple (n = 24) or complex (n = 20) fistulas. Preliminary results indicated an 84 percent healing rate by 3 to 8 weeks postoperatively, which progressively declined from 72.7 percent at 8 weeks to 62.4 percent at 12 weeks and 54.6 percent at a median follow-up of 6.5 (range, 3-13) months. Long-term Anal Fistula Plug closure rate was significantly higher in patients with simple than complex fistulas (70.8 vs. 35 percent; P < 0.02) and with non-Crohn's disease vs. Crohn's disease (66.7 vs. 26.6 percent; P < 0.02). Patients with two successive plug placements had significantly lower closure rates than patients who underwent placement of the plug once (12.5 vs. 63.9 percent; P < 0.02). No significant difference in closure rates were found between patients with one vs. multiple fistula tracts. Postoperative complications included perianal abscess in five patients (3 Crohn's disease, 2 non-Crohn's disease). CONCLUSIONS: Anal Fistula Plug is most successful in the treatment of simple anorectal fistulas but is associated with a high failure rate in complex fistula and particularly in patients with Crohn's disease. Repeat plug placement is associated with increased failure. Given the relatively low morbidity associated with the procedure, Anal Fistula Plug should be considered as a first-line treatment for patients with simple fistulas and as an alternative in selected patients with complex fistulas.

RESUMO

PURPOSE: There is significant concern in the current literature over the safety of laparoscopic techniques in removal of the entire colon and rectum. The purpose of this study was to examine the results of a one-stage laparoscopic-assisted restorative proctocolectomy in patients with mucosal ulcerative colitis and familial adenomatous polyposis in a single institution experience. METHODS: All patients who underwent laparoscopic-assisted one-stage restorative proctocolectomy (29 mucosal ulcerative colitis; 3 familial adenomatous polyposis) over a 24-month period were followed up prospectively for short-term and long-term complications and functional outcome. RESULTS: There were 32 patients (17 males), with a median age of 32 years (range, 16-29 years). There were no conversions to open surgery. There were two intraoperative complications, an inconsequential rectal perforation during mobilization and one staple line misfire. There were 11 postoperative complications: 3 obstruction/ileus, 2 pouchitis, 2 wound infections, 2 strictures, 1 pelvic abscess, and 1 pouch leak (at the top of the "J"). Three patients required reoperation (1 temporary ileostomy, 1 lysis of adhesions, and 1 transpouch drainage). The median number of bowel movements was seven per day (range, 2-15). CONCLUSION: A one-stage laparoscopic-assisted restorative proctocolectomy can be performed effectively and safely. Given that techniques in laparoscopic large-bowel surgery are still evolving rapidly, the role of this operation in the surgical treatment of patients with mucosal ulcerative colitis and familial adenomatous polyposis is likely to expand in the near future.
