Development of colon cancer after liver transplantation for primary sclerosing cholangitis associated with ulcerative colitis

Between February 26, 1981, and July 30, 1987, 36 patients underwent orthotopic liver transplantation for primary sclerosing cholangitis associated with ulcerative colitis. Three of the 36 recipients died within 3 mo because of graft nonfunction or surgical complications. The other 33 (92%) lived for at least 1 yr. Two of the 33 died after 12 and 14 mo, respectively, of recurrent cholangiocarcinoma that was not diagnosed before transplantation. Four other patients died of recurrent liver failure (three cases) or immunoblastic sarcoma (one case) after 14, 21, 36 and 44 mo. Twenty‐seven (75%) of the patients are still alive 23 to 81 mo after transplantation. Two patients have been diagnosed as having colorectal cancer 11 and 21 mo respectively, after transplantation, for an overall incidence of 5.6% (2 of 36) and a corrected incidence of 6.5% (2 of 31) if the three early deaths and two later deaths caused by cholangiocarcinomas are excluded. It is not known whether colorectal malignancies were present but undetected at the time of transplantation or whether they developed afterward. It is clear that patients who undergo liver transplantation for primary sclerosing cholangitis associated with ulcerative colitis should have careful follow‐up of the colon, including colonoscopy and multiple biopsies of the colorectal mucosa. Whether proctocolectomy should be considered prophylactically after liver transplantation is an unresolved issue.(HEPATOLOGY 1990;11:477–480.)

Strategies for Reducing Blood Transfusions in Hepatic Resection

A comparison of 60 blood transfused and 71 nonblood transfused hepatic resection patients was done to evaluate strategies for reducing blood transfusions during hepatic surgery. There were no significant differences between the two groups with regard to preoperative laboratory data, except for prothrombin time and hematocrit value. The mean operative blood loss was 1990 ml and 760 ml in the blood transfused and nonblood transfused groups, respectively. A multivariate analysis suggested that the patient’s body weight, preoperative prothrombin time, and operative blood loss independently predicted the need for intraoperative blood transfusion. Major postoperative complications developed more frequently in the blood transfused group than in the nonblood transfused group (31.7 vs. 11.3%, p<0.005). These results suggest that the difference in operative blood loss between the two groups was related to the prolonged prothrombin time and a susceptibility for blood transfusion was found to exist particularly in patients with a lower hematocrit value as well as a lower body weight. Thus, the improvement of these preoperative laboratory data combined with avoiding the use of the hematocrit value as a determining factor for intraoperative transfusion could correspond to a reduction in operative blood loss, while curtailing the demands on blood bank facilities, and lowering the risk of postoperative complications

Liver transplantation: an unfinished product.

Liver transplantation has become an extraordinarily valuable and useful operation, but one that is not perfect and that has not been exploited to anything like its full potential. Better immunosuppression may become available soon as exemplified by developments with the Japanese drug, FK506. Improved preservation with the UW solution is already here. With these advantages, liver transplantation is certain to become far more widely used than at any time in the past. Examples were cited of innovative approaches using liver transplantation for the treatment of hepatic malignancies

Pancreatic complications following orthotopic liver transplantation

During fiscal year 1986, 40 out of 196 patients (21%) developed hyperamylasemia following orthotopic liver transplantation. The placement of a retropancreatic aortohepatic arterial interposition graft was associated with hyperamylasemia (p < 0.025). Eight patients (20%) developed clinically significant acute pancreatitis and its sequelae; abscesses and pseudocysts each in 2. Pancreatitis was attributable to the retropancreatic arterial graft in 4, viral infection in 2 and obstruction of the pancreatic duct in 1 patient. All 4 patients with arterial graft-related pancreatitis exhibited poor graft function immediately postoperatively, of whom 2 required retransplantation - both of which failed to function. Five patients died (63%); 2 from primary graft non-function, 2 due to sepsis and 1 from systemic cytomegalovirus infection. We conclude that acute pancreatitis after liver transplantation is a life-threatening complication which is often associated with graft non-function
