Ileal bypass and cholecystostomy are used in children with selected cholestatic diseases to lower the bile acid (BA) levels in bile and blood and improve outcome. The efficacy of a cholecystocolic bypass in achieving the same goals was investigated in guinea pigs. In the study group (n=7), a cholecystocolic bypass was performed using a jejunal graft interposed between the gallbladder and the cecum. In the control group (n=5), a cholecystojejunal bypass was performed with a similar graft implanted in the proximal jejunum. Total BA concentration was measured in bile and portal blood at surgery (D0) and 30 days later (D30) by pooling the concentrations of 7 individual BA. D30/D0 BA ratios were compared. All animals developed normally without clinical symptoms. A 76% reduction in the bile T-BA levels was observed in both groups (p<0.05). A 80% decrease of T-BA levels was observed in portal vein in study group (p<0.05), suggesting that ileal bile flow and BA ileal reabsorption were highly impaired. No change in portal vein BA levels was observed in control group. Cholecystocolic bypass led to a significant loss of bile acids in guinea pigs and might be considered for bile diversion in pediatric patients with selected cholestatic diseases.
OBJECTIVE: To identify factors associated with leakage following intestinal anastomosis in dogs and cats. DESIGN: Retrospective study. ANIMALS: 90 dogs and 25 cats. PROCEDURE: Medical records of all dogs and cats that underwent intestinal resection and anastomosis between 1991 and 2000 were reviewed, and information on 27 factors was recorded. RESULTS: Anastomotic leakage was identified in 13 of the 90 dogs but in none of the 25 cats. Preoperative factors significantly associated with development of anastomotic leakage in dogs included preoperative peritonitis, serum albumin concentration, a left shift, and indication for surgery (dogs with intestinal foreign bodies were more likely to have leakage than dogs that underwent surgery for any other cause). Postoperative and case management factors significantly associated with development of leakage included duration of hospitalization, supplemental alimentation, whether the dog ate the day after surgery, blood product administration, and outcome (died vs survived). Discriminant analysis was performed, and dogs with 2 or more of the following factors were predicted to develop anastomotic leakage: preoperative peritonitis, intestinal foreign body, and serum albumin concentration < or = 2.5 g/dL. The model accurately predicted whether leakage would develop in 67 of 80 (84%) dogs. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that a variety of factors may be associated with development of intestinal anastomotic leakage in dogs. In particular, dogs with 2 or more of the following risk factors are predicted to be at high risk for developing anastomotic leakage: preoperative peritonitis, intestinal foreign body, and serum albumin concentration < or = 2.5 g/dL.
We describe here the indications for and our experience with complex vascular reconstructions in living donor liver transplantation. From December 1999 to June 2002, 59 patients underwent liver transplantation, 51 receiving the right lobe, and 8 the left lateral lobe, as a graft from a living donor. The indication for interpositional grafts on the arterial side (6/59, 10%) were stenoses of the celiac trunk and after resection of the hepatic artery for oncological reasons in adults. In children, arterial interpositional grafts were performed in situations of long distances between the donor and recipient artery, or in cases of inflow release from the aorta in patients with small hepatic arteries. On the portal-venous side, one interpositional graft was performed after an oncological resection. Once the portal vein was partially arterialized because of insufficient inflow. We used veins from the recipient, and native or cryopreserved arterial homografts for these grafts. All patients were treated during the first 6 months after transplantation with aspirin only. During the follow-up we did not observe vascular complications. If required, vascular interpositional grafts in the arterial and portal-venous position can be performed without adding postoperative complications.
