ABSTRACT
Background: Secondary aortoenteric fistula is an iatrogenic complication after aortic reconstructive surgery presenting with gastrointestinal bleeding and/or infectious symptoms. Infrequently, it may manifest with nonspecific and atypical clinical signs. We present a case of necrotizing fasciitis of the thigh complicating secondary aortoduodenal fistula, diagnosed with CT-scan. Case presentation: A 67-year-old man with a history of an open aortic-bifemoral bypass 6 years ago was admitted for a progressively swollen and painful right thigh for the last month. Through laboratory and morphological (CT-scan) investigations, a secondary aortoduodenal fistula associated with necrotizing fasciitis of the right thigh was discovered. After general supportive care and empiric antibiotherapy, the patient underwent a prosthetic explantation, a resection of the perforated bowel with end-to-end anastomosis, and extensive debridement of the necrotic tissue of the thigh. No revascularization has been attempted. The patient died the next day of multiple organ failure. Conclusion: Secondary aortoenteric fistula is rare but with a poor prognosis. Clinical presentation is not always typical. A high index of suspicion is the most important factor for improving outcomes. There is not a consensus about optimal management. Axillo-bifemoral revascularization and subsequent graft removal seem to be the best therapeutic option.
ABSTRACT
AIM: Our aim was to report the main complications of the Meckel's diverticulum. METHODS: Our retrospective study concerns 42 cases of complicated Meckel's diverticulum, collected during one period of 18 active years from January 1988 to December 2005. The yearly impact is 2,33 cases/year. We excluded the asymptomatic Meckel's diverticulum, of fortuitous discovery during intervention. RESULTS: The middle age of our patients is 25 years, with extremes going from 2 to 74 years. The sex-ratio is 3,2. The diagnosis before intervention of the complicated Meckel's diverticulum was not evoked in any time. The clinical features were an acute intestinal closure in 22 cases, an appendicitis in 13 cases, an appendicular peritonitis in 6 cases, and an acute intestinal intussusceptions in one case. In any case, it is the surgical exploration that permitted to confirm the diagnosis of a complicated Meckel's diverticulum. The approach way was median in 27 cases, MacBurney in 13 cases, and laparoscopic in 2 cases. The surgical exploration showed peritonitis in 16 cases, one diverticulitis in 23 cases, an acute intestinal intussusception in one case, a tumour in one case, and haemorrhagic diverticulum's ulcer in one case. The treatment consisted in a segmental resection of ileum with end to end anastomosis (37 cases) and a cuneiform resection (5 cases). The histological exam showed heterotopy of gastric tissue in 12 cases, of pancreatic tissue in two cases, and a Burkitt's lymphoma on a diverticulum in one case. We noted a precocious death following a septic shock. CONCLUSION: The Meckel's diverticulum constitutes a most common benign malformation of the digestive tube. The prognosis is related extensively to the gravity of its complications that can benefit, not only of the contribution of the laparoscopic diagnosis, but also therapeutic.
