Isolated Sigmoid Colon Injury Following Blunt Trauma Abdomen - An Unusual Occurrence.

Colon injury is far more common in penetrating injury than blunt trauma. Blunt trauma to the abdomen is more likely to damage solid organs such as the liver, spleen, pancreas and kidneys. Colon injury in blunt trauma is severe and is associated with other organ injuries, making its diagnosis difficult. However, isolated sigmoid colon injury in blunt trauma is rare. We report a case of 42 year old male who presented to us with blunt trauma to abdomen following a fall on iron Jaal (Grid) with slipping of one lower limb between two iron bars. The patient presented 4 days after injury with tenderness and guarding all over abdomen. X-ray abdomen was normal, ultrasonogram of abdomen showed presence of free fluid. Patient was operated on clinical basis. A single perforation of size 2 cm×1 cm was present in proximal sigmoid colon and there was no other injury. The perforated colon loop was mobilized and brought to anterior abdominal wall as colostomy. Isolated sigmoid colon injury is rare presentation. Initial radiologic investigations and clinical presentation may be misleading.

Meta-analysis of end colostomy versus loop colostomy for preventive colostomy / 国际外科学杂志

Objective To compare the complications of end colostomy and loop colostomy for preventive colostomy,then to evaluate which one is superior to the other.Methods Studies and relevant literatures comparing end colostomy with loop colostomy for defunctiong colostomy were searched by PubMed,Springer and Embase Library.The rates of complications were pooled and compared using a Meta analysis.The risk ratios were calculated with 95％ confidence intervals to evaluate the safety and efficacy of each teachnique.Results Six nonrandomized studies were included,with 1999 patients in total.The Meta-analysis of the non-randomied studies showed a lower risk of stoma retraction (RR:0.21,95％ CI:0.04 ～ 0.99,P =0.05) and stoma prolapse (RR:0.23,95 ％ CI:0.05 ～0.99,P =0.05) in the end colostomy group,but the higher risk of ischemia and necrosis (RR:5.08,95％ CI:1.94 ～ 13.22,P =0.05).No other statistically significant difference was observed for other complications.Conclusions Each type of defuncyioning stoma has its advantages and disadvantages.The study endorses end colostomy stoma over loop colostomy.However,there is not a strong evidence for the superiority of one colostomy over another for colostomy patients.So,large scale RCTs and high quality studies are needed.

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.

A Subtotally Divided End-loop Colostomy for Unresectable Rectal Cancer

PURPOSE: Divided end-loop colostomy is recommended in some cases of unresectable rectal cancer or anal incontinence, because a conventional loop colostomy is difficult to managing due to bulky stoma volume for a long period. In such case of the divided end-loop colostomy, severe inflammation may occur at the stoma site by poor conditions of the patient so that cause to be retracted or detached, and distal loop may be disrupted. To avoid these problems, we designed subtotally divided end-loop colostomy and studied its clinical effectiveness retrospectively. METHODS: About a 3 cm diameter, round skin incision as presumed colostomy size was made at the left lower abdomen, and entered the abdominal cavity by splitting the rectus muscle fibers. The caudal side of colon can be identified by confirming the fusioned taenia at the rectosigmoid colon level. After pulling out the colonic loop, the distal colon far from the lesion was subtotally divided by a GIA staple or manual suture, which cut obliquely 80% or 90% from the antimesenteric side of the distal loop while maintaining the 10% or 20% mesenteric side of the colonic loop. Then an end-loop colostomy is matured with a small fistularization of the distal loop as the undivided mesenteric side of colon. RESULTS: In 8 cases, subtotally divided colonic loop using a GIA staple. But in 9 cases, divided manually because of makedly thickened, edematous colonic wall resulting from prolonged obstruction. There were several mild complications, i.e. transient dermatitis in 5 cases, transient bulky stoma due to edema in 4 cases, mild retraction of stoma in 2 cases, and mild prolapse of stoma in 1 case. There were no major functional abnormalities during the follow-up period. CONCLUSIONS: Although we need to get further clinical experiences, the subtotally divided end-loop colostomy seems to be a useful alternative surgical procedure for unresectable rectal cancer.
