Abordaje abierto versus laparoscópico para la reconstitución del tránsito luego de la cirugía de Hartmann: resultados de una experiencia de 10 años / Open versus laparoscopic approach for Hartmann's reversal: results of a 10-year retrospective cohort study

Resumen Objetivo: El objetivo de este estudio es comparar los resultados perioperatorios del abordaje abierto (AA) con el abordaje laparoscópico (AL) para la reconstitución de tránsito (RT), y determinar factores de riesgo asociados a morbilidad posoperatoria. Material y Métodos: Se estudiaron pacientes consecutivos sometidos a RT entre enero de 2007 y diciembre de 2016 en nuestro centro. Se excluyeron aquellos con grandes hernias incisionales que requirieran reparación abierta simultánea. Se consignaron variables demográficas y perioperatorias, y se compararon ambos grupos. Además, se realizó una regresión logística para la identificación de factores de riesgo asociados a morbilidad posoperatoria en la serie. Resultados: Se realizaron 101 RT en el período. Se excluyeron 14 casos por hernia incisional, por lo que se analizaron 87 casos (46 AA y 41 AL). Diez pacientes en el grupo AL (24,4%) requirieron conversión, principalmente por adherencias. La morbilidad total de la serie fue de 36,8%, siendo mayor en el AA (50% vs 21,9%, p = 0,007). Hubo una filtración anastomótica en cada grupo. La estadía posoperatoria fue de 5 (3-52) días para el AL y 7 (4-36) días para el AA (p < 0,001). En la regresión logística, sólo el AA fue un factor de riesgo independientemente asociado a morbilidad posoperatoria (OR 2,89, IC 95% 1,11-7,49; p = 0,029). Conclusión: El abordaje laparoscópico se asocia a menor morbilidad y estadía posoperatoria que el abordaje abierto para la reconstitución del tránsito pos-Hartmann. En nuestra serie, el abordaje abierto fue el único factor independientemente asociado a morbilidad posoperatoria.

Introduction: Hartmann's reversal (HR) is considered a technically demanding procedure and is associated with high morbidity rates. Aim: The aim of this study is to compare the perioperative results of the open approach (OA) with the laparoscopic approach (LA) for HR, and to determine the risk factors associated with postoperative morbidity. Material and Methods: Consecutive patients undergoing HR between January 2007 and December 2016 at a university hospital were included. Patients with large incisional hernias that required an open approach a priori were excluded from the analysis. Demographic and perioperative variables were recorded. Analytical statistics were carried out to compare both groups, and a logistic regression was performed to identify risk factors associated with postoperative morbidity in the series. Results: A hundred and one HR were performed during the study period. Fourteen cases were excluded due to large incisional hernias, so 87 cases (46 OA and 41 LA) were analyzed. Ten patients in the LA group (24.4%) required conversion, mainly due to adhesions. The total morbidity of the series was 36.8%, being higher in the OA group (50% vs. 21.9%, p = 0.007). There was one case of anastomotic leakage in each group. The length of stay was 5 (3-52) days for LA and 7 (4-36) days for OA (p < 0.001). In the logistic regression, the OA was the only independent risk factor associated with postoperative morbidity in HR (OR 2.89, IC 95% 1.11-7.49; p = 0.029). Conclusion: A laparoscopic approach is associated with less morbidity and a shorter length of stay compared to the open approach for Hartmann's reversal. An open approach was the only factor independently associated with postoperative morbidity in our series.

Fechamento de colostomias: com ou sem estudo do cólon? / Colostomy closure: with or without pre-operative colon study

O estudo pré-operatório do cólon para fechamento de colostomias em alça devido a trauma vem perdendo importância nos últimos anos. A necessidade de se avaliar as alterações anatômicas pós-traumáticas do cólon vai de encontro aos custos, desconforto e morbidade dos exames. OBJETIVO: analisar a real necessidade do estudo prévio do cólon no fechamento de colostomia pós-trauma. MÉTODO: foram analisados, retrospectivamente, 98 prontuários de pacientes, no período de janeiro de 2004 a janeiro de 2006, portadores de colostomia em alça confeccionada após traumatismo e que foram alocados em dois grupos: grupo A, composto de 32 casos com estudo do cólon e o grupo B, 66 casos sem estudo colônico prévio. RESULTADOS: 94,9 por cento dos pacientes eram do sexo masculino e a média de idade foi de 27 anos. O tempo de permanência da colostomia foi, em média, 32,8 meses, sendo o flanco esquerdo a localização mais comum em ambos os grupos. A morbidade geral foi de 7,1 por cento, sendo 3,1 por cento de complicações no grupo A e 9,1 por cento no grupo B (p=0,16) e sem mortalidade. A complicação mais freqüente foi hematoma da parede abdominal em cinco casos (5,1 por cento), e apenas um caso de infecção de ferida operatória (1 por cento), e mais um de deiscência de anastomose (1 por cento). CONCLUSÃO: o estudo pré-operatório do cólon para fechamento de colostomia feita após trauma colorretal é dispensável.

The pre-operative study of the colon before loop colostomy closure in trauma patients has been loosing its importance since last few years. The need of evaluating the pos-traumatic anatomic alterations of the colon goes against the costs and morbidity of the examinations. OBJECTIVE: to analyze the real necessity of the colon study before colostomy closure in trauma patients. METHODS: a retrospective study of 98 patients submitted to colostomy closure after trauma, from January of 2004 to January of 2006 was carried out. They were divided in two groups: group A, composed of 32 patients with previews colon study and group B, composed of 66 patients without it. RESULTS: 94.9 percent of all patients were male and the average age was 27 years old. The time interval between colostomy and its closure was in average 32.8 months. The left side location was the most common sight. Overall morbidity was 7.1 percent, being 3.1 percent in group A and 9.1 percent in group B (p=0,16). The operative mortality was zero in both groups. The most common complication was wound haemathomas (5,1 percent) and only one case of wound infection. Anastomosis dehiscence occurred also in only one case, from group B. CONCLUSION: the pre-operative study of the colon for loop colostomy closure in trauma patients is not necessary.

The Complications of Stoma Take-down

PURPOSE: The study aimed to investigate the complications accompanying stoma take-down and to elucidate the significant factors associated with complications. METHODS: We recruited 341 patients who underwent stoma take-down in our hospital between January 2000 and December 2005. Data on various complications during this procedure, i.e., wound infection, prolonged ileus, and anastomotic leakage, were collected with respect to patient- and operation-associated parameters. RESULTS: Complications of stoma take-down developed in 72 (21.1%) patients: 53 (20.3%) patients in a loop ileosotmy, 10 (21.3%) patients in a loop colostomy, and 9 (27.3%) patients in a Hartmann colostomy, The overall complication rate was significantly associated with the urgency of the primary operation (elective vs. emergent, 17.8% vs. 29%, P=0.017), and with the operation time ( 80 min, 16.5% vs. 29.3%, P=0.005). Among the complications, ileus developed in 46 (13.5%) patients, wound infection in 17 (5.0%) patients, and anastomotic leakage in 5 (1.5%) patients. Wound infection was related to the type of stoma between a loop ileostomy and a Hartmann colostomy (3.5% vs. 12.1%; P=0.014), but no other factors were associated with other complications. CONCLUSIONS: There were significant differences in overall complications in relation to urgency of the primary operation and the operation time, but there was no statistical difference in complications between a loop ileostomy and a loop colostomy take- down groups. The significance of these factors appears to be reduced with accurate surgical technique and patient care.

Loop Colostomy with Not Everted Fashion for Rectal Cancer

PURPOSE: An anastomotic leak after resection of rectal cancer is a omnious complication. The diverting stoma is performed to avoid this serious complication. However, a diverting stoma and a stoma reversal are associated with significant morbidity and a small mortality. As stoma-related complications are associated with a delay of adjuvant therapy for advanced rectal cancer, minimal stoma-related morbidity is mandatory for rectal cancer patients. A safe and simple dissection of the stoma is known to be associated with less morbidity at stoma closure. Since in a loop colostomy of a not everted fashion, it is easy to construct and dissect the peristomal site at colostomy reversal, this study evaluated the usefulness of a protective loop colostomy of a not everted fashion in rectal cancer. METHODS: We reviewed the clinical records of 71 cases of loop colostomy closure for rectal cancer between January 1996 and December 2004. The clinical data, including indications for the stoma, the clinicopathologic features of the patients and their general conditions, the data for patients receiving adjuvant therapy, stoma-related morbidity, stoma-closure-related morbidity, and perioperative data were examined. RESULTS: Indications for stoma creation are the discretion of the surgeon (n=22), poor bowel preparation (n=21), unstable anastomosis (n=16), bowel obstruction (n=6), and anastomotic leakage (n=6). The stoma-related morbidity rate for a non-eversion colostomy was 5.6%. Morbidity events were peristomal erythema (n=2), prolapse (n=1), and parastomal hernia (n=1) requiring surgery. The stoma-closure-related morbidity rates was 9.9%. In the 45 patients undergoing adjuvant therapy, colostomy closure was performed during adjuvant therapy in 39 patients. Major complications, such as anastomotic leakage or abscess following reversal of the non-eversion colostomy, occurred in 1 of the 71 patients (1.4%). The average operating time and the blood loss for clostomy closure were 89.5 minutes and 202.3 ml, respectively. A simple closure of the loop colostomy was performed in 51 patients (71.8%). CONCLUSIONS: Based on our results, a non-eversion colostomy may be considered due to the ease of construction and reversal if a temporary diverting stoma for rectal cancer is indicated.

Clinical Analysis of Complications in Abdominal Stoma Surgery

PURPOSE: This study was undertaken to review the complications associated with ileostomy, colostomy construction and subsequent closure. METHODS: We retrospectively reviewed 74 patients with ileostomy and colostomy closure from August 1, 1995 to June 30, 1999. RESULTS: The complications of stoma construction occurred in 15 patients (20.3%) among 74 patients: skin problem in 10 cases, prolapse in 4 cases, and stoma necrosis, retraction and stenosis in 1 case, respectively. Factors such as age, underlying pathology, type of stoma did not contribute to the complications of stoma construction. Complications of stoma closure occured in 15 patients (20.3%): wound problem in 9 cases, enterocolitis in 4 cases and anastomotic leakage in 2 cases. With respect to stoma closure, only old age was associated with increased morbidity (P<0.05), rather than method of closure, time interval to closure, or type of stoma. Mean operation time for simple closure was 122.2 minutes and 204 minutes for resection and anastomosis. The mean hospital stay was 9.6 days for simple closure and 13 days for resection and anastomosis. CONCLUSIONS: The morbidity associated with stoma construction and subsequent closure was appreciable. There were no specific risk factors influencing the complications of ileostomy or colostomy construction, but old age increased morbidity after closure.

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.

Closure of the Colostomy

PURPOSE: To investigate the timing of colostomy closure and the associated risk factors that affect the development of complication after colostomy closure. METHODS: We have reviewed and analyzed the results of 28 patients with colostomy closure at the Kwangju Christian Hospital from January 1993 to December 1997. We investigated to associated literatures on this subject for timing of colostomy closure, preparing a patient for colostomy closure, suture technique, wound management, underlying disease process related to the incidence of complication and experience of surgeons. RESULT: Wound infection developed in 4 patients (14.4%). Anastomotic leakage occurred in one patient (3.6%). Small bowel obstruction developed in two patients (7.2%). Overall incidence of complication was 25%. The incidence of complications in patients with trauma who underwent colostomy was 44.4% and patients without trauma, 15.8%. Complication rate was 16.6% for loop colostomies and 40% for end colostomies. The morbidity was 40% for colostomies on the left side, 18.7% for transverse colostomies, and 0% for colostomies (2 ileostomies) on the right side. The morbidity rate for closures within 6 weeks for the initial operation was 50%; for those within 6 to 12 weeks, 8.3%; and for those after 12 weeks, 16.6%. CONCLUSION: The optimal timing of closure varies from patient to patient, but closure within 6 weeks of the initial operation significantly increased the morbidity. Colostomies on the left side are associated with a higher morbidity rate than transverse colostomies or colostomies on the right side.
