Arteriovenous fistulas between the inferior mesenteric artery and vein are rare, with only 26 primary and secondary cases described in the literature. Secondary fistulas occur following operations of the left hemicolon and manifest as abdominal pain, abdominal mass, gastrointestinal bleeding, colonic ischemia and portal hypertension. Symptom intensities are flow-dependent, and can range from minimal symptoms to severe heart failure due to left to right shunt. Diagnosis is usually established by radiological or intraoperative examination. Treatment options include embolization and/or surgical resection. Therapeutic decisions should be adapted to the unique characteristics of the fistula on an individual basis. A new case of a primary arteriovenous fistula is described and discussed along with a complete review of the literature. The patient in this report presented with signs and symptoms of colonic ischemia without portal hypertension. The optimal treatment for this patient required a combination of embolization and surgical operation. The characteristics of these rare inferior mesenteric arteriovenous fistulas are examined and some considerations concerning diagnostic and therapeutic strategies that should be followed are presented. 相似文献

Since ancient times biliary surgery has been one of the major interests of doctors and other scientists around the world. From the ancient Greeks and Egyptians to the greatest scientists of modern times biliary surgery has advanced remarkably. Especially during the last century huge progress has been made in this field. Minimally invasive surgical techniques have been developed and combined with general anesthesia and antisepsis that have made biliary surgery particularly safe for every patient and have made cholecystectomy one of the most common operations in the world today. 相似文献

INTRODUCTION: Daclizumab (Dmab) is a genetically engineered humanized IgG1 monoclonal antibody that binds to the alpha chain of the interleukin-2 receptor (Tac, CD25, p55) expressed on activated human T lymphocytes. Dmab has been used in a clinical protocol of islet transplantation with satisfactory results. The aim of the present study was to evaluate the use of an antibody against the interleukin-2 receptor (Dmab) as an immunosuppressive agent in an experimental model of hepatocyte allotransplantation (allo-Tx) in rats with fulminant hepatic failure (FHF). MATERIALS AND METHODS: Six Wistar rats were used as donors and 48 Lewis rats as recipients: four groups of 12 animals each with induction of FHF and 24 hour later hepatocyte Tx--group A: no treatment; group B: cyclosporin (20 mg/kg days 0 to 5 and 10 mg/kg days 6 to 15); group C: Dmab (0.05 mg day of Tx and 0.05 mg day 7); and group D: Dmab and cyclosporine. Hepatocytes were transplanted intrasplenically. Animals were followed for 15 days. RESULTS: Statistical analysis showed better survival among groups C (83%, MST = 13) and D (92%, MST = 14.25) compared to groups A (max 72, MST = 1.5) or B (50%, MST = 9). Survival in group D was better but not significantly than group C. Biochemical evaluation and histology confirmed satisfactory function and engraftment, respectively. CONCLUSION: This experimental model showed the safe, effective use of Dmab. 相似文献

Primary duodenal diverticula are usually asymptomatic. About 115 perforations have been reported, but none with right colon necrosis. We report a 45-year-old woman, with a five days history of high fever along with epigastric and periumbilical pain. Physical examination revealed right upper and lower quadrant tenderness with peritoneal signs. White blood cell count was 11 500/mm (3) while biochemical and hepatic biology tests were normal. Abdominal radiographs showed no pathologic findings. Ultrasound disclosed fluid in the lower pelvis. Computerized tomography revealed fluid collection in the right hepatorenal space. Intraoperative findings included purulent fluid in the lower pelvis, segmental necrotic changes of the right colon, and a perforated diverticulum on the antimesenteric border of the third part of the duodenum. Surgery consisted of right hemicolectomy and ileo-transverse anastomosis, diverticulectomy, and decompressive lateral duodenostomy at the second duodenal portion. The patient had an uneventful postoperative course. A contrast study from the duodenostomy tube on the 6 (th) postoperative day showed no leakage or obstruction. Duodenostomy tube was removed on the 14 (th) postoperative day. Histology confirmed the diagnosis of a primary duodenal diverticulum. 相似文献

Purpose Bile duct injury (BDI) represents the most serious complication of laparoscopic cholecystectomy (LC). The aim of this retrospective single-institution study was to evaluate the real incidence of BDI during laparoscopic and open cholecystectomy (OC) in a tertiary academic center in Athens, Greece.Methods Between January 1991 and December 2001, 3 637 patients underwent cholecystectomy in our department; as LC in 2 079 patients (LC group) and as OC in 1 558 patients (OC group). All the LCs were performed or supervised by five staff surgeons and all the OCs were performed or supervised by another five staff surgeons.Results There were 13 BDIs associated with LC (0.62%) and 6 associated with OC (0.38%) (P = 0.317). There was one death associated with BDI after LC. Only two (15.4%) of the BDIs associated with LC occurred within the proposed learning curve limit of 50 LCs per individual surgeon.Conclusion Laparoscopic cholecystectomy is safe and is not associated with a higher incidence of BDI than OC. Moreover, we did not find that the learning curve for LC affected BDI occurrence. 相似文献

Liver resection in cases of isolated hepatic actinomycosis: case report and review of the literature 总被引:1,自引:0,他引:1
Felekouras E Menenakos C Griniatsos J Deladetsima I Kalaxanisi N Nikiteas N Papalambros E Kordossis T Bastounis E 《Scandinavian journal of infectious diseases》2004,36(6-7):535-538
Hepatic actinomycosis is an uncommon entity that forms communicating abscesses and fistulae. We report a 53-y-old immunocompetent male patient with hepatic actinomycosis. Symptoms included intermittent fever, abdominal pain, right upper quadrant tenderness and jaundice. A hepatic tumour mass was found on abdominal sonography and computerized tomography. Two preoperative percutaneous core biopsies of the mass were not diagnostic. The above findings were highly suggestive for liver abscess or purulent primary liver neoplasm. Treatment with intravenous antibiotics was continued for 20 d, but both symptoms and liver ultrasound findings remained unchanged. The patient underwent exploratory laparotomy and right posterior segmentectomy of the liver. Pathological examination of the surgically removed specimen disclosed hepatic actinomycosis. Following operation the patient remains in excellent condition without evidence of recurrence. 相似文献

The operative management of the pancreatic stump after pancreaticoduodenectomy has been shown to be an important factor influencing the postoperative development of pancreatic fistula. Thus far, there is no ideal technique for reconstruction, and end-to-end pancreaticojejunostomy (PJS) represents the preferable method. Comparative analysis of early postoperative outcome was done between two groups of patients who underwent either end-to-end PJS or pancreatic remnant ligation (PRL) after pancreaticoduodenectomy. Between January 1997 and December 2001, 39 consecutive patients underwent pancreaticoduodenectomy at the 1st Department of Surgery, University of Athens Medical School. All operations were performed or supervised by two senior surgeons, and all patients underwent a Whipple's procedure. After pancreaticoduodenectomy, 23 patients underwent end-to-end PJS (PJS group), whereas the remaining 16 patients underwent PRL without pancreatic reconstruction (PRL group). We compared the two groups in terms of patients' characteristics, clinical presentation, serum laboratory values on admission, operative details, and postoperative course. The morbidity and mortality rates were 15.4% and 5.1%, respectively, for the whole series. In the PJS group, the morbidity rate was 8.7%, the pancreatic fistula formation rate was 4.3%, and the mortality rate was 4.3%. In the PRL group, the morbidity rate was 25%, the pancreatic fistula formation rate was 12.5%, and the mortality rate was 6.25%. These differences were not statistically significant. There were two deaths in the whole series (one in each group); however, none of the deaths were related to pancreatic fistula formation. Hospital stay was similar in both groups. Both PJS and PRL are valid surgical options that correlate with acceptable postoperative incidence of pancreatic fistula formation, morbidity, and mortality rates. Although PRL avoids the construction of the most risky anastomosis, the results of this study show that early postoperative results after PRL are not superior to PJS; therefore, the method should not be considered as the treatment of choice for the pancreatic stump after a Whipple's procedure. Meticulous surgical technique, surgical experience, and close postoperative care are essential for a successful outcome after this major abdominal operation. 相似文献
