Consensus of Chinese experts on treatment of prolapsed hemorrhoids with transanal stapler / 中华胃肠外科杂志

Prolapsed hemorrhoids is a common clinical disease, and severe symptoms can significantly affect work and life. The transanal stapler has the advantages of simple operation and less trauma in treating prolapsed hemorrhoids. Its clinical efficacy is closely related to the selection of indications, the standardization of surgical operations, and the prevention and treatment of complications. In current clinical practice, there is no consensus on the treatment of prolapsed hemorrhoids with transanal stapler. Hence a discussion was held by the Professional Committee of Colorectal Diseases of Chinese Society of Integrated Chinese and Western Medicine, concerning the indications, contraindications, operating specifications and perioperative management of prolapsed hemorrhoids. A consensus was consequently formed, aiming to provide a guideline for the clinical practice.

Technical innovation: Intragastric Single Port Sleeve Gastrectomy (IGSG). A feasibility survival study on porcine model

Abstract Purpose: To perform technically the laparoscopic sleeve gastrectomy (LSG) using a unique Intragastric Single Port (IGSG) in animal swine model, evidencing an effective and safe procedure, optimizing the conventional technique. Methods: IGSG was performed in 4 minipigs, using a percutaneous intragastric single port located in the pre-pyloric region. The gastric stapling of the greater curvature started from the pre-pyloric region towards the angle of His by Endo GIA™ system and the specimen was removed through the single port. In the postoperative day 30, the animals were sacrificed and submitted to autopsy. Results: All procedures were performed without conversion, and all survived 30 days. The mean operative time was 42 min. During the perioperative period no complications were observed during invagination and stapling. No postoperative complications occurred. Post-mortem examination showed no leaks or infectious complications. Conclusion: Intragastric Single Port is a feasible procedure that may be a suitable alternative technique of sleeve gastrectomy for the treatment of morbid obesity.

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.

Procedimiento para prolapso y hemorroides como cirugía ambulatoria / Procedure for hemorrhoids and mucosal prolapse as a day surgery

Introducción: Estudios prospectivos randomizados demostraron que la técnica "Procedimiento para Prolapso y Hemorroides" (PPH) es eficaz. Si bien esta cirugía reduce el dolor postoperatorio pocas publicaciones la incluyen como procedimiento ambulatorio. El objetivo de este trabajo es evaluar la factibilidad, la seguridad y los resultados del uso de PPH en forma ambulatoria para el tratamiento de la enfermedad hemorroidal. Diseño: Observacional retrospectivo. Pacientes y métodos: Se analizó una base de datos completada en forma prospectiva que incluía todos los pacientes operados de hemorroides con técnica PPH entre mayo del 2005 y mayo del 2009 bajo anestesia general con alta programada el mismo día del procedimiento. Resultados: En este período de 4 años de 74 pacientes operados con técnica PPH, 63 ingresaron bajo Cirugía Mayor Ambulatoria (85,1 por ciento). 41 pacientes (65 por ciento) fueron de sexo masculino. La edad promedio fue de 55 (28-79) años. El tiempo quirúrgico promedio fue 48,1 (20-120) minutos. 53 pacientes (84 por ciento) cumplieron con éxito el régimen ambulatorio, con internación promedio de 5,2 (2.2-9.2) horas. 10 pacientes (16 por ciento) debieron pernoctar en el hospital por diferentes causas: 4 por dolor intenso, 2 por vómitos, 1 por retención aguda de orina, 1 por hipotensión, 1 por eritema perianal y 1 por sangrado postoperatorio que requirió reoperación. 7 pacientes (11 por ciento) presentaron complicaciones postoperatorias tempranas (entre día 1 y 28 postoperatorio): 3 hematoma perianal, 1 trombosis externa, 1 fisura anal, 1 tenesmo rectal por edema de sutura y 1 dehiscencia de la hemorroideopexia. Con un seguimiento postoperatorio promedio de 24 (12 a 14) meses se han registrado 2 estenosis (3,1 por ciento) que se resolvieron con dilataciones y 7 recidivas (11.1 por ciento) que se resolvieron 6 con bandas elástica y 1 con PPH...

Background: Stapled haemorrhoidopexy has been shown in randomized controlled trials to be associated with less postoperative pain and an earlier return to normal activities. Given the decreased postoperative pain and no need for wound care, stapled haemorrhoidectomy should be feasible as a day surgery procedure. The objective of this study is to assess the safety, feasibility and results of stapled haemorrhoidopexy as day surgery procedure. Study design: Descriptive retrospective evaluation. Patients and methods: This is a retrospective study based on a prospective collected database. All consecutive patients with haemorrhoids who underwent stapled haemorrhoidopexy as day surgical procedure between May 2005 and May 2009 were included. Pre and perioperative parameters, early and late postoperative complications and long term results were analyzed. Results: In this period, PPH was performed in 74 patients. Of these, 63 (85 per cent) patients were considered appropriate candidates for day case surgery. 41 (65 per cent) were men and average age was 55 (28-79) years. Average operative time was 48 (20-120) minutes. 53 patients (84 per cent) successfully underwent stapled haemorrhoidopexy on a day case basis and the average hospital stay was 5.2 (2.2-9.2) hours. Ten patients (16 per cent) did not complete successfully the day case surgery and require staying at the hospital. Indications for admission were acute postoperative complications were as follow: four for analgesia, two for vomits, one for urinary retention, one for hypotension, one for perianal erythema and one for early postoperative bleeding who need reoperation. 7 patients (11 per cent) had early postoperative complications (1-28 days after surgery): 3 perianal hematoma, 1 thrombosis of the external haemorrhoidal plexus, 1 anal fissure, 1 tenesmus and 1 anastomotic dehiscence...

Stapling tapering enteroplasty with end to end single layer anastomosis in neonatal intestinal atresia

Jejunoileal atresia [JIA] is one of the major causes of neonatal intestinal obstruction. During the past two decades a better understanding of the etiology and improvements in anesthetic and preoperative care have led to significant improvement in survival. The survival rate of JIA in the Western literature is over 89%[2, 3, 4, 5, 6] .Morbidity and mortality in JIA have always been a concern in pediatric surgery, particularly the technique of tapering and anastomosis. To evaluate the outcome of single layer end to end anastomosis with proximal stapling enteroplasty. 38 neonates born with [JIA] from April 2003 to April 2010 were operated upon. Of the 38 neonate underwent end to end anastomosis with stapling enteroplasty without resection of the proximal segment. 35 of them are doing well. The other 3 deaths were in patients who had severed co-morbid diseases. Although the overall motility was 3/38 [0.78%].No other complications were observed

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).

Mucosectomía con estapler (PPH) como alternativa quirúrgica para los hemorroides / PPH stapling mucosectomy as treatment for hemorrhoids

La hemorroidectomía es una excelente técnica para hemorroides grado III a IV pero va asociada invariablemente a dolor postoperatorio. La mucosectomía con estapler (PPH, Ethicon®) ha demostrado menores cifras de dolor y recuperación más rápida pero los seguimientos han sido aún breves. Objetivo: Se presenta nuestra experiencia con la técnica PPH, evaluando dolor postoperatorio, complicaciones y recidiva a largo plazo. Material y método: Se analizan los protocolos prospectivos de pacientes operados de hemorroides grado III- IV ó prolapso mucoso entre Abril de 2000 y Junio de 2004 en nuestro servicio, seleccionándose según posibilidad de adquirir el instrumento PPH. Se evaluó dolor postoperatorio con escala EVA, siendo el seguimiento semanal por 1 mes, a los 6 meses y finalmente control telefónico. Resultados: Se estudian 62 pacientes (29 hombres, 33 mujeres). La hospitalización promedio fue de 1,4 días (1-3) y el tiempo quirúrgico de 39 minutos (20-60). El 94 por ciento de los pacientes no refirió dolor o éste fue leve (EVA 0-3). Seis pacientes (10 por ciento) presentaron sangrado postoperatorio leve que cedió espontáneamente. Dos pacientes se reoperaron precozmente, uno por fisura anal persistente y otro por trombosis de hemorroides externos. En una media de seguimiento de 22 meses (rango 4 a 54 meses) a 43 pacientes (70 por ciento de la serie), la recidiva fue de 9,3 por ciento.

Reconstitución de la operación de Hartmann con suturas mecánicas: análisis de 65 pacientes consecutivos / Reconstruction of colonic transit after Hartmann procedure using mechanical sutures: analysis of 65 patients

Antecedentes: El restablecimiento del tránsito colónico luego de la operación de Hartmann es una intervención de complejidad variable que podría facilitarse con el empleo de la suturas mecánicas. El objetivo de este estudio es analizar los resultados de esta intervención efectuada con anastomosis grapada. Método: Estudio prospectivo de una serie de pacientes consecutivos sometidos a una colorrectoanastomosis mecánica (CRA) luego de la operación de Hartmann, lo que se compara con una serie histórica de la Institución efectuada con sutura manual. Resultados: Se trata de 65 pacientes con un promedio deedad de 56 años (extremos 20-81), el 40 por ciento de ellos portadores de una o más condiciones co-mórbidas. Lapatología de base fue el cáncer colorrectal en el 37 por ciento de los casos, la enfermedad diverticular en el 32 por ciento y el trauma en el 12 por ciento. El tiempo promedio entre la operación de Hartmann y la reconstitución fue 6,8 meses (extremos 2,5-60). La intervención se efectuó en forma abierta en 53 pacientes y por vía laparoscópica en 12, a 5 de las cuales hubo que convertir por el intenso proceso adherencial. El tiempo de hospitalización fue en promedio de 10,5 días (extremos 3-35). La morbilidad global fue 15 por ciento, hubo 3 reoperaciones (4,6 por ciento), un caso de fístula anastomótica de manejo conservador y no hubo mortalidad. Al comparar esta serie con la histórica de la Institución, se aprecia una reducción significativa del tiempo operatorio en la cirugía abierta, una mayor proporción de pacientes con enfermedad diverticular y una disminución de la infección del sitio operatorio (p<0,05). El seguimiento promedio en esta serie es de 40 meses (extremos 4-87) y hay 53 pacientes en control. La estenosis benigna de la anastomosis ocurrió en 6 casos (9,2 por ciento), de los cuales 3 son asintomáticos y 3 (4,6 por ciento) han sido sometidos a una dilatación endoscópica. Conclusión: La CRA grapada tiene resultados globales similares a la...

Mid-term Outcomes of Side-to-Side Stapled Anastomosis in Cervical Esophagogastrostomy

This study was conducted to evaluate the mid-term results of cervical esophagogastric anastomosis using a side-to-side stapled anastomosis method for treatment of patients with malignant esophageal disease. A total of 13 patients were reviewed retrospectively from January 2001 to November 2005 who underwent total esophagectomy through a right thoracotomy, gastric tube formation through a midline laparotomy and finally a cervical esophagogastric anastomosis. Average patient age was 62.6 yr old and the male to female ratio was 11:2. The mean anastomosis time was measured to be about 32.5 min; all patients were followed for about 22.8+/-9.9 months postoperatively. There were no early or late mortalities. There were no complications of anastomosis site leakage or conduit necrosis. A mild anastomotic stricture was noted in one patient, and required two endoscopic bougination procedures at postoperative 4th month. Construction of a cervical esophagogastric anastomosis by side-to-side stapled anastomosis is relatively easy to apply and can be performed in a timely manner. Follow up outcomes are very good. We, therefore, suggest that the side-to-side stapled anastomosis could be used as a safe and effective option for cervical esophagogastric anastomosis.

Stapled hemorrhoidectomy: present status

OBJETIVO: Avaliar se a eficácia da técnica de hemoirrodectomia por grampeamento é maior do que a tradicional, assim como analisar a relação custo-benefício antes de seu emprego rotineiro. FONTES DE DADOS: Analisaram-se retrospectivamente, várias publicações mundiais de ensaios randomizados, no período de 2000 a 2004, em que se compararam a intensidade da dor, o tempo de retorno às atividades profissionais, a importância de incontinência fecal e outras complicações no período pós-operatório de grupos de pacientes submetidos a ambas as técnicas, durante diferentes períodos de seguimento clínico. CONCLUSÕES: A técnica de hemoirrodectomia por grampeamento propicia menor intensidade de dor e retorno mais precoce às atividades profissionais, quando comparada à hemoirrodectomia convencional. Entretanto, sua eficácia não foi determinada, uma vez que ainda não estão disponíveis estudos prospectivos e randomizados com grandes casuísticas e seguimentos a longo prazo.

Suturas mecánicas en cirugía colorrectal: análisis de 225 pacientes consecutivos / Mechanical sutures in colorectal surgery: analysis of 225 consecutive patients

Se presenta la experiencia prospectiva con el uso de suturas mecánicas en cirugía colorrectal en 225 pacientes intervenidos en forma consecutiva en un período de 4 años, la mitad del sexo masculino con un promedio de edad de 51,3 años (extremos 15-91). La principal patología de base fue el cáncer colorrectal (52 por ciento), seguida de la enfermedad diverticular (17 por ciento) y el megacolon (16 por ciento). Se utilizó un total de 331 grapadoras, 88 pacientes requirieron más de una carga y el instrumento más empleado fue el circular en el 80 por ciento de los casos, lo que está determinado básicamente por la patología de base y el tipo de intervención. La anastomosis colorrectal (CRA) se empleó en el 61 por ciento de los casos, seguida de la ileorrectoanastomosis (IRA) en el 13 por ciento. La grapadora circular más utilizada fue las de 28-29 mm en el 59 por ciento (106/181). Problemas técnicos intraoperatorios ocurrieron en el 5,8 por ciento de los casos, los que se corrigieron satisfactoriamente sin complicaciones posteriores. La técnica de insuflación de aire para comprobar la hermeticidad de las CRA, IRA y los reservorios se realizó en todos los casos. El porcentaje global de dehiscencia anastomótica fue de 22 por ciento, con mayor riesgo en la anastomosis rectales extraperitoneales muy bajas, aunque esta diferencia no fue estadísticamente significativa. La técnica de doble grapado utilizada en 26 pacientes presentó una fístula (5,2 por ciento), mientras que la anastomosis terminal funcional empleada en 44 pacientes se complicó con una deshiscencia en 2 casos (4,5 por ciento). Debido a complicaciones de la anastomosis mecánica debieron reoperarse 4 pacientes (3 por dehiscencia y un caso de estenosis) y sólo en un caso se deshizo la anastomosis, con una mortalidad global específica de 0,4 por ciento. La anastomosis mecánica es una alternativa válida en cirugía colorrectal, con índices de morbilidad comparables con la cirugía convencional y es especialmente útil en la construcción de una anastomosis a nivel del recto bajo

Técnica del PPH en el tratamiento quirúrgico de los hemorroides internos grado III: análisis críticos / PPH technic in the surgical treatment of grade III internal hemorrhoids: critical analysis

Se comunican los resultados de un protocolo prospectivos para evaluación de la técnica del PPH en el tratamiento de las hemorroides internos grado III con un seguimiento mínimo de 6 meses. En un período de 10 meses se intervinieron 10 pacientes en forma consecutiva, 6 hombres y 4 mujeres, con un promedio de 50 años (extremos 36-69) cuyos síntomas principales eran el prolapso hemorroidal que requiere maniobras de reducción manual, la rectorraga y el prurito. Se utilizó eñ set PPH 1 diseñado para el procedimiento que utiliza una grapadora circular de 33 mm. Ocho de 10 pacientes requirieron de suturas hemostáticas adicionales. La distancia de la línea de sutura a la línea pectínea fue de 3 cm como promedio (extremos 1,5-5). Según el número de dosis de análgesicos solicitados el dolor fue catalogado como leve en 3 pacientes, moderado en 4 e intenso en 3. En el control de los 7 días, dos pacientes presentan dolor, uno de los cuales se prolonga por 2 meses sin una explicación clara. A los 30 días, 3 pacientes refieren sangrado rectal escaso e intermitente, uno de ellos con relación a un granuloma de la línea de sutura, uno secundario a recidiva del prolapso y uno sin hallazgos patológicos. En la evaluación final efectuada entre 6 y 18 meses, 7 pacientes describen el procedimiento como excelente o bueno, 2 como regular (sangrado rectal intermitente y plicomas residuales) y uno como malo (recidiva). El prolapso hemorroidal se controló satisfactoriamente en 9 casos. El PPH es un método reproducible y eficiente en el control del prolapso hemorroidal con una reducción del dolor postoperatorio y del tiempo de cicatrización, lo que recientemente se ha demostrado en estudios controlados

Stapling techniques in colorectal cancer surgery

This prospective non-randomized study was performed on 65 patients with carcinoma of the colorectal region undergoing a stapler anastomoses using the ILS stapler system. The overall incidence of complications was 36.9% [15.3% general complications and 21.6% related complications]. The possibly related general complications were seven cases of wound infections and one case of wound dehiscence. While, the unrelated general complications [3%] were one case of hematemesis and another one as pulmonary embolus. As regards the related complications, five cases of leakage, five cases of stricture and four cases of local recurrence were reported. The duration of surgery varied from 90 to 190 minutes with a mean time of 125 minutes; while, time consumed to create and complete anastomosis varied from 10 to 20 minutes with a mean time of 14 minutes. Sphincter functions were not affected via endoscopic and manometric examination. The stapled anastomosis was ten times expensive [EP 600] than other ordinary techniques [EP 60]. Hospital stay after surgery ranged from 10 to 27 days with a mean stay of 14.9 days. There was no mortality
