Intra-Operative Contrast Cholangiography in Living Donor Liver Transplantation: The ISMETT Experience.

BACKGROUND: We evaluated the clinical impact of donor biliary anatomy discrepancies (DBAD) achieved by comparing pre-operative evaluation obtained with magnetic resonance (MR)/magnetic resonance cholangiopancreatography (MRCP) imaging, with intra-operative cholangiography (IOC) on the living related liver donor (LDLT) and recipient. METHODS: This single-center, retrospective study included 97 consecutive adult-to-adult (A2A) LDLT performed in our hospital in the last 12 years. Donor sex and age, living donors with biliary and/or vascular anomalies, recipient age, sex, primary etiology, re-transplantation, Model of End-Stage Liver Disease score, co-morbidities, arterial and biliary recipient complications assessed on the basis of clinical follow-up were collected and analyzed for significance through the use of a multivariate linear regression model. RESULTS: Biliary complications in the donor (DBC) were detected in 8 (8.2%) cases. Biliary complications in the recipients (RBC) were detected in 38 (39%) cases. DBADs were found in 32 (33%) cases and resulted strictly related to RBC (P = .05). CONCLUSIONS: After adjusting for co-variables, results of the linear regression analysis confirmed that DBAD is an independent predictor of RBC, but it is not significantly associated with vascular complications or patient survival. We showed that RBCs after LDLT were influenced by DBAD.

Two brothers with renal and hepatic polycystic disease treated with combined liver and kidney transplantation: a case report.

We report two brothers with renal and hepatic polycystic disease who developed end-stage renal failure, requiring hemodialysis, and organomegaly syndrome related to the gigantic size of the liver and both kidneys. Although there was no liver failure, combined liver and kidney transplantation was performed owing to worsening of the clinical condition. In both cases, successful transplantation was accomplished with intra-abdominal engraftment of the liver and kidneys through the same abdominal incision.

Development of a standardized model for liver failure in pigs: anatomopathophysiologic findings after extended liver resection.

Eighteen pigs weighing a mean 19 ± 4 kg, were divided into group 1 (n = 2), that underwent resection of the left lateral lobe, group 2 (n = 2), resection of the left median and right median lobes; and group 3 (n = 18), resection of the left lateral, left median, right median, and right lateral lobes. All animals were followed for 5 days. Liver failure (n = 8) leading to animal death within 3 days after surgery was observed in 65% of group 3, whereas no group 1 or 2 animal experienced liver insufficiency. Multivariate analysis revealed that the extent of liver resection expressed as a percentage of total body weight <2.3%, international normalized ratio > 1.6 as postoperative day 2, serum bilirubin > 4.2 on postoperative day 2, and serum lactates > 9 mmol/L after resection were independent predictors of liver failure (P < .05). The number of resected liver lobes was not a good predictor of liver failure in swine, whereas the extent of resection expressed as a percentage of total body weight was an independent predictor of early liver failure. A resected liver-to-body weight ratio >2.3% was associated with a 65% probability of developing liver insufficiency. This parameter may be useful when developing a model of liver failure after extended liver resection in swine.

Laparoscopic approach for an intra-abdominal kidney allograft nephrectomy after pediatric transplantation: a case report.

We report a case of minimally invasive nephrectomy of a kidney transplanted into the abdominal cavity in a child. A 15-year-old girl underwent transplantation with a cadaveric donor kidney due to congenital pyelonephritis, vesicoureteral reflux, and secondary bladder atrophy. The transplant was complicated by hyperacute rejection, cytomegalovirus infection, and anastomotic stenosis of the Bricker neobladder. After recurrent urinary tract infections, the patient was reintroduced to hemodialysis in 2010. After pneumo-peritoneum, we placed 2 10-mm trocars in the hypochondrium and left side and 2 5-mm in the left iliac fossa and right upper quadrant. The transplanted kidney was skeletonized, the artery and vein were cut to the end-to-side anastomoses to the juxta-renal aorta and cava using an automatic 35-mm, stapler, and the ureter was dissected and closed with clips. Via a Pfannestiel minilaparotomy we extracted the allograft. The patient was discharged on the third postoperative day. After 4 months of follow-up, she is alive an on dialysis. Laparoscopic nephrectomy of a kidney transplanted into the abdominal cavity is feasible and safe in centers with skilled minimally invasive techniques.
