Radical cystectomy with W-shaped orthotopic ileal neobladder constructed with non-absorbable titanium staples-long term follow-up

Purposes We retrospectively assessed our experience with the W-shaped orthotopic ileal pouch, which was constructed with non –absorbable titanium staples. For these purpose, we discuss the results of bladder capacity, urinary continence and early and long-term postoperative complications. Materials and Methods We included in the study 17 patients who underwent radical cystoprostatectomy followed by construction of an orthotopic W-shaped ileal pouch between October 2000 and November 2009. A 65-70 cm segment of ileum was isolated and prearranged into a W- configuration, leaving two 10 cm intact segments on both sides of the ileal fragment. In our technique we entirely anatomized all adjacent limbs in order to create a sphere-shaped pouch. The ureters were directly anastomized to both intact segments of the ileal division. All our patients underwent pouchscopy 6 months after operation and annually. Results Mean operative time for neobladder reconstruction and ureteral anastomoses was 87 ± 7.67 minutes. In one patient a leak from the ileo-ileal anastomosis was confirmed on the 3rd day after operation. In 2 cases unilateral stricture of the ureteral-neobladder anastomosis was documented. Staple lines were mostly covered with ileal mucosa after 6 months. The mean functional bladder capacity was 340 ± 27.6 mL and 375 ± 43.4 mL at 6 and 12 months, respectively. First-year daytime and nighttime continence was good and acceptable in 90% and 78% of patients, while it increased to 95% during the 2nd year. Conclusions The long term follow-up shows that non-absorbable titanium staples can be safely used for creation of an orthotopic ileal neobladder. However, these data should be further validated in a larger series of patients. .

Modulación del crecimiento en osteodistrofia renal / Growth modulation in renal osteodystrophy

Introducción: La osteodistrofia renal provoca desejes progresivos en los miembros inferiores y la deformidad más frecuente es el genu valgo. El crecimiento guiado (hemiepifisiodesis) es útil para corregir deformidades angulares en la edad pediátrica. El objetivo de este trabajo es mostrar los resultados y las complicaciones de esta técnica quirúrgica aplicada a fisis patológicas. Materiales y métodos: Se presentan 11 pacientes (20 rodillas) con diagnóstico de insuficiencia renal crónica y genu valgo, tratados en nuestro Servicio con hemiepifisiodesis transitoria. Se colocaron placas en 8 en 4 pacientes y grapas en los 7 casos restantes. Se evaluaron el eje mecánico radiográfico preoperatorio y posoperatorio, y las complicaciones relativas a cada implante. Resultados: Se logró la corrección completa en 4 pacientes, un caso sobrellevó deformidad rebote y, en los restantes, se obtuvo una mejoría sin llegar a la normalización óptima del eje mecánico. Conclusiones: La corrección obtenida se relaciona claramente con la normalidad de la función renal. Los pacientes trasplantados consiguieron una normalización en el crecimiento óseo remanente. No se hallaron diferencias en los resultados ni en las complicaciones entre los dos tipos de implantes empleados. Nivel de evidencia: Serie de casos, Nivel IV.

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.

Revisiting stapled and handsewn loop ileostomy closures: a large retrospective series

OBJECTIVE: To compare the surgical outcomes of stapled and handsewn closures in loop ileostomies. METHODS: The data of 225 patients requiring loop ileostomies from 2002 to 2007 were retrospectively evaluated. The patients underwent partial small-bowel resections and either handsewn or stapled anastomoses for the ileostomy closures. They were followed up postoperatively with routine surgical examinations. RESULTS: The study group consisted of 124 men and 101 women with a mean age of 49.12 years. The ileostomy closure was performed with handsewn in 129 patients and with stapled in 96 patients. The mean time to the first postoperative flatus was 2.426 days in the handsewn group and 2.052 days in the stapled group (p <0.05). The mean time to the first postoperative defecation was 3.202 days in the handsewn group and 2.667 days in the stapled group (p <0.05). The mean duration of patient hospital stay was 8.581 days for the handsewn group and 6.063 days for the stapled group (p <0.05). CONCLUSIONS: Patients who underwent ileostomy closure with stapled recovered faster in the postoperative period and required shorter hospital stays than those whose closures were performed with handsewn. In our opinion, stapled should be considered the gold standard for loop ileostomy closures.

Doble engrapado en cirugía colorrectal / Double stapler technique in colorectal surgery

BACKGROUND: Colorectal surgery has evolved significantly during the last 35 years. The circular stapler and the double stapler techniques have favored the development of very low rectal anastomoses with reduction in anastomotic leakage. The objective of this study is to evaluate the functional results and complication rate of this surgical technique in the Department of Colorectal Surgery at the Hospital de Especialidades, Centro Medico Nacional Siglo XXI and at the Hospital Angeles del Pedregal, both located in Mexico City. METHODS: Clinical records of patients who underwent surgery from May 1995 to December 2005 using the double stapler technique and performed by the authors were reviewed. RESULTS: The study included 142 patients, 55 of whom had rectosigmoid cancer resections. Average age was 60.1 years (male predominance 52.05%). The circular stapler most frequently used was CDH 33 (Johnson & Johnson). Average distance between the anal margin and the anastomoses for extended low anastomoses was 3.21 cm (low 7.8 cm and high 13.7 cm), and the rate of anastomoses leak was 3.52%. CONCLUSIONS: Double stapler technique used to treat rectosigmoid pathology is safe, secure and assures intestinal continuity in low anterior as well as extended low anterior resections with primary anastomoses. In those patients with associated risk factors and low extended low anterior resection with primary anastomoses, we recommend performing a protective stoma (ileostomy).
