[Amputation of the rectum via laparoscopy].

We report the case of a 66-year-old woman with a bleeding adenocarcinoma of the lower thirty of the rectum. The laparoscopic procedure was initiated with mobilization of the sigmoid colon. The left ureter was identified as it crosses the left iliac vessels. The peritoneum along the right side of the rectosigmoid mesentery was transected. The superior rectal artery was divided utilizing extracorporeal ligatures. The anterior rectum was separated from the uterus, the pararectal tissue was mobilized, the middle rectal arteries were ligated and the posterior rectum was dissected from the presacral tissue. The perineal component of the procedure was simultaneously performed. The sigmoid loop was extracorporeally transected with a linear stapler. The proximal sigmoid end was exteriorized through the colostomy site (site of the left superior port). The distal sigmoid end was replaced in the abdominal cavity and was grasped through the perineal wound; the anus, rectum and sigmoid were removed through the perineal wound. The feasibility of this procedure has been well established. However, it seems to be an alternative for the classical abdominoperineal resection as treatment for adenocarcinoma of the lower rectum. His superiority has yet to be confirmed by future studies.

[Liver transplantation--considerations over 8 cases operated in the year 2000].

In the year 2000, at the Department for General Surgery and Liver Transplantation from The Fundeni Clinical Institute Bucharest, seven OLTs and one living-related transplantation were performed in 6 adults and 2 children. Postoperative complications were: bile leakage, hemoperitoneum, lower gastrointestinal hemorrhage, parietoabdominal hematoma. There was only one postoperative death due to septic complications in the 18th p.o.d. and one late death due to pneumonia of unknown origin. After the results in the year 2000 there was an increased number of donors and referrals. We consider that now in Romania this is an established program that will continue depending on the number of donors and financing.

[Orthotopic liver transplantation in adult patients with cadaveric grafts. Experience of the Fundeni Center of General Surgery and Liver Transplantation].

We analyze the experience of the Center of General Surgery and Liver Transplantation from the Fundeni Clinical Institute (Bucharest, Romania) regarding orthotopic liver transplantation (OLT) in adult recipients, with whole liver grafts from cadaveric donors, between April 2000 (when the first successful LT was performed in Romania) and December 2004. This series includes 37 OLTs in adult recipients (16 women and 21 men, aged between 29-57 years--average 46 years). Other two LT with whole liver cadaveric grafts and two reduced-size LT were performed in children; also, in the same period, due to the acute organ shortage, other methods of LT were performed in 28 patients (21 living donor LT, 6 split LT and one "do mino" LT), that were not included in the present series. The indications for OLT were HBV cirrhosis--10, HBV+HDV cirrhosis--4, HCV cirrhosis--11, HBV+HCV cirrhosis--2, biliary cirrhosis--5, Wilson disease--2, alcoholic cirrhosis--1, non-alcoholic liver disease--1, autoimmune cirrhosis--1. With three exceptions, in which the classical transplantation technique was used, the liver was grafted following the technique described by Belghiti. Local postoperative complications occurred in 15 patients (41%) and general complications in 17 (46%); late complications were registered in 18 patients (49%) and recurrence of the initial disease in 6 patients (16%). Intrao- and postoperative mortality was 8% (3/37). There were two patients (5%) who died because of immunosuppressive drug neurotoxicity at more than 30 days following LT. Four patients (11%) died lately because of PTLD, liver venoocclusive disease, recurrent autoimmune hepatitis and liver venoocclusive disease, myocardial infarction, respectively. Thirty-four patients survived the postoperative period (92%); according to Kaplan-Meier analysis, actuarial patient-survival rate at month 31 was 75%.

[Central pancreatectomy--indications, technique, outcomes].

Central pancreatectomy is a conservative resectional procedure indicated for benign and low malignant tumors located in the neck and/or body of the pancreas. We report our experience on 5 patients and some considerations about this surgical technique from medical literature.

[Repeat hepatic resections].

Five cases of iterative liver resections are presented, out of a total of 150 hepatectomies performed between 1.01.1995-1.01.1998. The resections were carried out for recurrent adenoma (one case), cholangiocarcinoma (two cases), hepatocellular carcinoma (one case), colo-rectal cancer metastasis (one case). Only cases with at least one major hepatic resection were included. Re-resections were more difficult than the primary resection due, first of all, to the modified vascular anatomy. Intraoperative ultrasound permitted localization of intrahepatic recurrences. Iterative liver resection appears to be the best therapeutical choice for patients with recurrent liver tumors.
