Reconstrucción poscirugía de Hartmann / Stoma reversal after the Hartmann's procedure

RESUMEN Antecedentes: la reconstrucciónn del tránsito intestinal luego de una operación de Hartmann es un procedimiento habitualmente complejo y con alta morbilidad. Objetivo: analizar la tasa de reconstrucción después de la cirugía de Hartmann y resultados posoperatorios en nuestra experiencia. Material y métodos: análisis retrospectivo de pacientes a los que se les practicó la reconstrucción del tránsito intestinal posterior a una cirugía de Hartmann en un período 16 años. Revisamos la bibliografía y nuestra base de datos. Luego traspasamos la información disponible a una grilla de datos construida con variables habitualmente analizadas en la literatura. Finalmente, analizamos los resultados mediante medidas básicas de tendencia central. Resultados: en 16 años realizamos 92 operaciones de Hartmann, de las cuales 69 (75%) llegaron a la reconstrucción. Edad promedio: 58 años. El 52% de los pacientes fueron hombres. La operación de Hartmann fue de urgencia en el 48% y 58% resultaron malignas. Tiempo transcurrido hasta la reconstrucción: en promedio, 9 meses, y el 90% (N 62) de los casos se realizó por vía laparoscópica. Morbilidad general 38% y ajustada a los grados III y IV de Clavien-Dindo fue 11,5%. No hubo mortalidad. Conclusión: los resultados obtenidos son semejantes a los publicados y nuestra experiencia nos motiva a continuar eligiendo el abordaje laparoscópico.

ABSTRACT Background: Background: Stoma reversal after Hartman's operation is usually a complex procedure and is associated high morbidity. Objective: To analyze the rate of reversal after the Hartmann's procedure and the postoperative outcomes in our experience. Material and methods: We conducted a retrospective analysis of patients undergoing reversal after the Hartmann's procedure over a 16-year period with review of the literature and of our database and transferred the available information to a data grid constructed with variables commonly analyzed in the literature. Finally, we analyzed the results using basic measures of central tendency. Results: Over a 16-year period, we performed 92 Hartmann's operations; 69 (75%) reached the reversal stage. Mean age was 58 years and 52% were men. Forty-eight percent of the Hartmann's procedures were emergency surgeries and 58% were due to cancer. Mean time to reversal was 9 months and 90% (n = 62) were laparoscopic procedures. Overall morbidity and adjusted for complications grade III and IV of the Clavien-Dindo classification were 38% and 11.5%, respectively. None of the patients died. Conclusion: The results obtained are similar to those published and our experience motivates us to continue choosing the laparoscopic approach.

Primary adenocarcinoma at colostomy site: report of a clinical case

Colorectal cancer (CRC) is the fourth most frequently diagnosed cancer in the United States and it is found in 17% of patients thought to have complicated diverticular disease. However, primary adenocarcinoma rarely occur in the colostomy site and the risk of developing malignancy is similar to that of any other colonic segment. Polyps found in CRC screenings can be divided into the following types: hyperplastic polyps, polyps with no malignant potential, adenomatous polyps, polyps with malignant potential, and malignancies. Local complications of the colostomy can appear in the immediate, early, or late postoperative period, with an incidence ranging from 15 to 30%; neoplasia is even less common. (AU)

Analysis of Risk Factors for the Development of Incisional and Parastomal Hernias in Patients after Colorectal Surgery

PURPOSE: The purpose of this study was to evaluate the overall rate and risk factors for the development of an incisional hernia and a parastomal hernia after colorectal surgery. METHODS: The study cohort consisted of 795 consecutive patients who underwent open colorectal surgery between 2005 and 2007 by a single surgeon. A retrospective analysis of prospectively collected data was performed. RESULTS: The overall incidence of incisional hernias was 2% (14/690). This study revealed that the cumulative incidences of incisional hernia were 1% at 12 months and 3% after 36 months. Eighty-six percent of all incisional hernias developed within 3 years after a colectomy. The overall rate of parastomal hernias in patients with a stoma was 6.7% (7/105). The incidence of parastomal hernias was significantly higher in the colostomy group than in the ileostomy group (11.9% vs. 0%; P = 0.007). Obesity, abdominal aortic aneurysm, American Society of Anesthesiologists score, serum albumin level, emergency surgery and postoperative ileus did not influence the incidence of incisional or parastomal hernias. However, the multivariate analysis revealed that female gender and wound infection were significant risk factors for the development of incisional hernias female: P = 0.009, wound infection: P = 0.041). There were no significant factors related to the development of parastomal hernias. CONCLUSION: Our results indicate that most incisional hernias develop within 3 years after a colectomy. Female gender and wound infection were risk factors for the development of an incisional hernia after colorectal surgery. In contrast, no significant factors were found to be associated with the development of a parastomal hernia.

Fechamento precoce das colostomias em pacientes com trauma do reto: um estudo prospectivo e casualizado / Early colostomy closure in patients with rectal trauma: a prospective randomized trial

Foi feito um estudo prospectivo e casualizado de 35 pacientes portadores de colostomias devido a lesões traumáticas do reto admitidos no Hospital Jõao XXIIII no período de novembro de 1994 a junho de 1997. O objetivo foi avaliar os resultados do fechamento precoce das colostomias nestes pacientes. Após o atendimento inicial, os pacientes foram sorteados de acordo com o número do registro de admissão em dois grupos: os do grupo 1 (N = 14) foram submetidos ao fechamento precoce da colostomia programado para o 10o dia pós-operatório do tratamento da(s) lesão(ões) e os do grupo 2 (N = 21) submetidos ao fechamento tardio da colostomia, programado para oito semanas após a operação inicial. Nos dois grupos, o restabelecimentodo trânsito intestinal somente foi realizado após o fechamento da lesão retal confirmado por um estudoradiológico contrastado. Houve um predomínio de pacientes jovens, do sexo masculino e vítimas de traumatismopenetrante. Todos eram portadores de uma colostomia em alça. A taxa global de complicações após o fechamento das colostomias foi de 25,7%, com a infecção de ferida operatória sendo a complicação mais freqüente (17,1%). No grupo 1, as complicações ocorreram em 35,7% dos casos e, no grupo 2, em 19,1% (p = 0,423). A análise dos resultados permitiu-nos concluir que a taxa de complicações, a duração da operação para o fechamento da colostomia e o tempo total de permanência hospitalar não apresentaram diferenças significantes entre os dois grupos. Os pacientes submetidos ao fechamento precoce (grupo 1) permaneceram apenas 10 dias em média com a colostomia, enquanto nos pacientes do grupo 2 a média de permanência com a colostomia foi de 66,3 dias (p< 0,001 - Teste de Kruskal-Wallis). Baseados nestes resultados, concluímos que os pacientes portadores de...

A prospective and randomized trial involving 35 rectal trauma patients who were colostomized, as part of their surgical treatment, was undertaken at the João XXIII Hospital, between November 1994 and June 1997. The aim of this study was to evaluate the early results colostomy closure in this patient population. Rectal trauma victims were assigned for two groups, according to their hospital number. Group 1: Early colostomy closure, on the 10th post-operative day, and Group 2, delayed closure, eight weeks after theinitial operation. A contrast study of the rectum was performed in all patients prior to colostomy closure, in order to confirm the rectal healing. The majority were young male victims of penetrating trauma. All patients were submitted to a loop colostomy prior to the colostomy closure. The global complication rateafter colostomy closure was 25.7%. Postoperative wound infection was the most commom complication (17.11%). Complications occurred in 35.7% of the cases in group 1 and 19.1% in group 2(p = 0,423 ). We concluded that there was no significant difference between groups regarding complication rate, operative time for colostomy closure, and total hospital stay. Patients undergoing early closure (Group 1) stayed with a colostomy for an average of 10 days, while patients from delayed closure (Group 2) had their colostomy for an average of 66.3 days (p<0.001 - Kruskal-Wallis Test). Based on our findings, traumatic rectal injury victms who have a colostomy as part of their surgical treatment, may undergo earlycolostomy closure on the 10th post-operative day, as long as no complication of the initial operation ispresent.
