Role of Liver Transplantation in Bilio-Vascular Liver Injury After Cholecystectomy.

BACKGROUND: The aim of this study was to report 2 cases of liver transplantation (LT) for iatrogenic bile-vascular injury (BVI) sustained during cholecystectomy and to review the literature for LT after cholecystectomy. METHODS: Between March 2001 and July 2013, within our institution, 12 patients were treated after cholecystectomy, 3 of 12 received LT, 1 for acute de-compensation in a cirrhotic patient and 2 after iatrogenic lesions. RESULTS: The majority of iatrogenic injury occurred during video-laparocholecystectomy (63,6%; 7/11). Three patients of 12 (25%) received LT: the first patient developed acute de-compensation in chronic and after liver failure. The second patient developed recurrent cholangitis and secondary biliary cirrhosis. The third patient had undergone emergency hepatectomy because of bleeding and subsequent total hepatectomy with porto-caval shunt. Five of 12 (42%) patients were treated with bilio-digestive anastomosis: 1 patient with direct repair on T-tube; 2 patients (17%) with arterial vascular lesion requiring surgical treatment; and 1 patient treated with medical therapy. No deaths occurred. The post-operative morbidity included 1 re-intervention, 3 recurrent cholangitis, 1 anastomotic biliary stricture, 1 anastomotic bile leak, and cholestasis in 3 patients. The overall hospital stays were higher after LT. Median follow-up was 8.25 years (range, 2-14). CONCLUSIONS: The management of iatrogenic injury during cholecystectomy depends on the time of recognition, extent of injury, experience of the surgeon, and the patient's general condition. If safe repair is possible, BVI should be treated promptly, otherwise all patients should be treated in an experienced center.

Predictability and survival in liver replantransplantation: monocentric experience.

Liver retransplantation is the only treatment for patients with hepatic graft failure. Due to the shortage of organs, it is essential to optimize its use. Between 1998-2010, our center performed retransplantations on 48 (12.8%) patients (re-OLT). The data are compared with those for a group of 374 patients who did not receive retransplantations (NO re-OLT). The re-OLT vs NO re-OLT groups did not significantly differ in mean age of recipients (47 vs 51 years), indications for transplantation (hepatitis C virus cirrhosis 54% vs 56%, alcoholic cirrhosis 25% vs 17%, hepatocellular carcinoma 14% vs 22%), mean Model for End-stage Liver Disease (25 vs 20), mean total cold ischemia time (385 vs 379 minutes), or mean age of donors (52 vs 49 years). The main causes of retransplantation were primary graft nonfunction (64%), arterial thrombosis (8%), biliary complications (6%), and hepatitis C virus recurrence (4%). The difference in overall patient survival was not statistically significant. The patient's survival at 1, 3, 5, and 10 years for RE-OLT vs NO-reOLT was 56% vs 63%, 53% vs 60%, 46% vs 57%, and 44% vs 53%, respectively. Multivariate analysis identified Model for End-stage Liver Disease≥23 as a predictor factor of retransplantation (P=.04). Other variables predicting outcome included age of donors (≥65 years vs younger group), age of recipients (≥50 years vs younger group), cold ischemia (≥600 vs <600 minutes), and transplantation indications (hepatitis C virus, hepatitis B virus, alcohol, and others). The retransplantation performed between 8-15 days appeared to have worse results than those in other periods (0-7 days, 16-30 days, 1-6 months, >6 months). The incidence of re-OLT in the series (12.8%) was comparable to that in the literature, and primary graft nonfunction in the study represents the main cause of retransplantation. Our analysis showed that the indication of the first transplant and the age of the donor were not risk factors for re-OLT. Liver retransplantation is a concrete alternative lifesaver for patients with graft failure.

Torque Teno Virus--cause of viral liver disease following liver transplantation: a case report.

Torque Teno Virus (TTV), a nonenveloped human virus of the Circoviridae family, is hepatotropic, causing liver damage, cirrhosis, and, rarely, fulminant hepatitis. It prevails in 10% to 75% of blood donors due to environmental differences, independent of chronic hepatitis B virus (HBV)/HCV hepatitis, cryptogenic cirrhosis, alcoholic cirrhosis, and in fulminant hepatitis non-A-G. Reports about the efficacy of clinical alpha interferon are rare. In July 2007, a 65-year-old man who was serologically negative for A-E viruses presented with acute liver failure due to a ruptured hepatic artery aneurysm and underwent orthotopic liver transplantation (OLT). Immunosuppression was based on cyclosporine and steroids. At postoperative day 20, there was persistent hypertransaminasemia with otherwise normal liver function. A percutaneous hepatic biopsy documented pattern suggestive of a viral etiology. Multiple tests for hepatotropic viruses in the donor and the recipient from the pre- and post-OLT periods remained negative. Only the TTV qualitative test, assessed by polymerase chain reaction (PCR) on patient sera, was positive. Immunosuppressive therapy was not changed; no antiviral therapy was undertaken. At 6 months posttransplantation, transaminase levels spontaneously normalized and the clinical situation was unchanged. No complications were observed; the patient is in good clinical condition. No graft rejection was observed. In histologically proven non-A-E viral hepatitis, it is important to consider TTV as an incidental pathogenic agent. It may be useful to extend virological tests to TTV among transplant recipients and donors and to gain further knowledge about this virus.

Renal transplant compartment syndrome: a case report.

An unusual case of early double kidney transplant dysfunction due to abdominal compartment syndrome is herein reported. A 62-year-old woman on peritoneal dialysis underwent dual kidney transplantation. The grafts were positioned extraperitoneally in both iliac possae using standard techniques. Surgical procedures and immediate postoperative period were uneventful. The urine output was immediate and the creatinine decreased, but in a few days she developed severe ascites with reduced urine output, increased creatinine, and progressive changes on Doppler ultrasound. The patient underwent paracentesis: the kidney function recovered as well as the Doppler ultrasound. Kidney biopsy was negative for rejection or renal pathology. Graft dysfunction was related to the presence of ascites. A catheter inserted in the abdomen measured intra-abdominal pressure (IAP) of 14 mm Hg. IAP correlated with renal function showing that IAP probably explained renal flow modifications.

[Surgery for complicated colonic diverticulitis. Our experience]. / Risultati del trattamento chirurgico nelle complicanze della diverticolite del colon. Esperienza dell'ultimo ventennio.

During the last two decades were observed 422 symptomatic patients with various degree of diverticular disease of the colon. 51 patients underwent surgery: 29 for stenosis (24) or occlusion (5), 4 for fistulas, 18 for perforation. The operations (26 emergencies, 25 elective) included: 21 cases of one-stage resection and anastomosis without protective colostomy, 16 with colostomy, 8 Hartmann's procedures, 7 Mikulicz's operations, 1 suturing of the diverticulum with colostomy. The incidence of complications was 17.6% (9 cases, 7 following emergency surgery and 2 after elective procedures). The intraoperative mortality was zero, while postoperative 5.8% (3 cases, 2 after emergency procedures and 1 following elective surgery). The best results (lowest morbidity and mortality rates) occurred with the radical procedures, especially the resection-anastomosis with or without colostomy, which allowed the removal of the septic focus from the peritoneal cavity and thus a shorter recovery in a high number of cases.
