Abstract
Modern oncological liver surgery continues to push the limits of resectability by incorporating an array of new developments in the fields of surgery, anaesthesia and intensive care, oncology, radiology and transplantation medicine. New criteria for determining the resectability of primary and secondary liver tumours have been developed and introduced into national consensus guidelines. Modern tools for improving oncological outcome include the rapid induction of liver hypertrophy prior to major liver resection, downstaging of tumours with advanced chemotherapy protocols, minimally invasive local therapies like radiofrequency ablation and chemo- or radioembolisation, and liver transplantation for non-resectable hepatocellular carcinoma.

Abstract
The long-term effect of conversion from calcineurin inhibitor (CNI) therapy to an mTOR inhibitor requires clarification. Following completion of the 12-month, open-label, multicenter ZEUS study, in which 300 kidney transplant recipients were randomized to continue cyclosporine (CsA) or convert to everolimus at 4.5 months posttransplant, outcomes were assessed at month 36 (n = 284; 94.7%). CNI therapy was reintroduced in 28.4% of everolimus patients by month 36. The primary efficacy endpoint, estimated glomerular filtration rate (Nankivell, ANCOVA) was significantly higher with everolimus versus the CsA group at month 24 (7.6 mL/min/1.73 m(2) , 95%CI 4.3, 11.0 mL/min/1.73 m(2) ; p < 0.001) and month 36 (7.5 mL/min/1.73 m(2) , 95%CI 3.6, 11.4 mL/min/1.73 m(2) ; p < 0.001). The incidence of biopsy-proven acute rejection from randomization to month 36 was 13.0% in the everolimus arm and 4.8% in the CsA arm (p = 0.015). Patient and graft survival, as well as incidences of malignancy, severe infections and hospitalization, were similar between groups. Kidney transplant patients who are converted from CsA to everolimus at month 4.5 and who remain on everolimus thereafter may achieve a significant improvement in renal function that is maintained to 3 years. There was a significantly higher rate of rejection in the everolimus arm but this did not exert a deleterious effect by 3 years posttransplant.

Abstract
Colon perforation due to diverticulitis is a life-threatening complication in the postoperative course of kidney transplantation. In the immunocompromised patient a diagnosis of diverticulitis is difficult to make. We report a 53-year-old woman being kidney transplanted 14 years ago with known diverticulosis. She was admitted with acute severe pain in the lower left abdomen. Abdominal computed tomography (CT) scan indicated a diagnosis of intestinal abscess in the small pelvis. Laparotomy showed a covered sigma perforation with abscess located in the small pelvis (Hinchey-I). Because of the immunocompromised situation of the patient we performed a Hartmann procedure. Her postoperative course was uneventful. In a 6-month interval the intestinal continuity restoration was performed. Twelve days after discharge the patient was readmitted with reduced renal function and increased infection parameters. During physical examination the abdomen was tender. The patient complained of abdominal pain in the left upper abdomen and additional pain in the left shoulder. An antibiotic therapy using ciprofloxacin was already initiated owing to a urinary tract infection. An abdominal CT scan was performed and indicated an intestinal abscess in the left upper abdomen. Laparotomy showed an abscess involving transverse colon, distal jejunum, and proximal ileum (Hinchey-II). Segmental resection of the left colonic flexure, proximal jejunum, and ileum was performed. The postoperative course was uneventful and the patient was discharged on the 8th postoperative day. The present casuistry emphasizes that the immunocompromised patient can undergo diverticulitis twice, and that primary anastomosis is a feasible option for patients with localized peritonitis due to complicated diverticulitis.

Abstract
PURPOSE Due to the persistant organ shortage for kidney transplantation, donor selection has changed in the past years. Although hypertension and diabetes mellitus are known to be risk factors for renal insufficiency, kidneys from donors with these diagnoses in their history have been accepted for kidney transplantation even with an increased risk of poor graft function. Herein we have reported our experience with kidney transplantation using grafts from donors with both, a history of type II diabetes and hypertension. METHODS Between 2000 and 2005, ten patients were grafted using donors with history of type II diabetes mellitus and hypertension. Mean donor age was 58 +/- 7.5 years and recipient age, 52.2 +/- 15.7 years. Mean HLA mismatch was 0.8 (A); 1.2 (B) and 0.9 (DR). Cold ischemia time was 17.4 +/- 4.1 hours. Immunosuppression was based on CyA (n = 7), tacrolimus (n = 2) or sirolimus (n = 1). RESULTS Six patients (60%) showed good initial function, and four (40%) had delayed graft function (DGF). One patient died at ten weeks due to multiorgan failure. Two (20%) biopsy-proven rejections were diagnosed, one of which was resistant to therapy. Six months after kidney transplantation, 7 (77%, n = 9) showed good graft function (creatinine 1.3 to 2.4 mg/dL), but one patient displayed long-lasting DGF with poor function. CONCLUSION Grafts from donors with a history of diabetes mellitus and hypertension are suitable for kidney transplantation. Elevated rate of DGF (40%) would justify allocation of these organs to local transplant centers to shorten ischemia time and thereby reduce DGF and achieve better long-term results. Identification and detailed evaluation of these donors prior to allocation (eg, HbAlc, biopsy) may help transplant centers to accept these kidneys.

Abstract
PURPOSE The organ shortage has led to increasing acceptance of living donation in all transplant centers. Although the risk of impaired long-term outcome seems to be greater using elderly donors, these organs are not generally refused for transplantation. We report our experience with 25 living donor kidney transplantations from donors older than 60 years. METHODS Between 1995 and 2004, 124 living donor procedures were performed in our center from 83 related and 41 unrelated donors. Twenty-five donors (19 female, 6 male) were 60 years or older (mean, 65.3 +/- 3.9 years). The recipient included (10 females and 15 males) showed a higher degree of variance in age (46.1 +/- 14.6 years). The immunosuppressive protocol was cyclosporine (CyA)-based regimen in related cases and tacrolimus-based in unrelated cases. RESULTS We transplanted 16 left and 9 right kidneys from older donors. The mean cold ischemia time was 171 +/- 64 minutes with a second warm ischemia time of 24 +/- 6 minutes. Severe arteriosclerosis made vascular reconstruction by graft interposition necessary in two recipients. The acute rejection rate was 20%. Two patients (8%) required dialysis in the early postoperative course, whereas initial function was excellent in 22 patients (88%). The mean serum creatinine concentration after 12 months was 1.6 +/- 0.3 mg/dL (n = 24) and 2.0 +/- 0.7 mg/dL (n = 16) at 4 years. In comparison, the mean creatinine concentration after 4 years in donors under 60 years was 1.6 +/- 0.9 mg/dL. Our analysis showed no significant difference in long-term graft function comparing young versus old donors in the setting of living donor transplants. CONCLUSION Using living donors older than 60 years for transplantation is a feasible and safe option. The difference in long-term creatinine between young and old donors was not significant.

Abstract
PURPOSE Ureteral necrosis is a serious problem in kidney transplantation. Sometimes re-ureterocystostomy is possible, while other cases require an elaborate reconstruction to maintain kidney function. We report our experience with ileum interposition for ureteral reconstruction. METHODS After 9 years of dialysis treatment a 58-year-old patient was grafted using the left kidney of a 59-year-old donor with a cold ischemic time of 9.5 hours. The early postoperative course was uneventful apart from delayed graft function. Immunosuppression consisted of an IL-2-receptor antibody, calcineurin inhibitor, mycophenolate mofetil, and corticosteroids. Discharge serum creatinine was 2.3 mg/dL. In month 4 the patient showed a pararenal urinoma; cystoscopy revealed necrosis of the distal ureter. Operative revision showed urine leakage from the renal pelvis through the urinoma into the bladder. As the whole ureter was necrotic, a re-ureterocystostomy was not possible. The patient's own ureter had been extirpated, and the bladder was too small to do a direct anastomosis between it and the kidney. Consequently, an ileum interposition was performed. RESULTS The postoperative course was uneventful. Kidney function was stable with a nadir creatinine concentration of 2.0 mg/dL 18 months' posttransplantation, and 14 months' post ileal interposition the kidney function was still satisfactory, with a creatinine level of 2.0 mg/dL. CONCLUSION Ureteral necrosis is a serious complication following kidney transplantation. Whenever a re-ureterocystostomy or an uretero-ureterostomy is not possible, the interposition of the ileal segment represented a safe procedure to deal with this problem.

Abstract
INTRODUCTION Recipients of related (R) and unrelated (NR) living donor kidney transplantations (LDKTX) receive immunosuppressive (IS) therapy 5 days in advance in order to achieve low rates of acute rejection episodes. We herein report the different IS regimens for R and NR transplants as well as acute rejection and primary function rates. METHODS Ninety-five LDKTX (69% R, 31% NR) were performed with mean cold ischemia time (CIT) of 145 +/- 32 minutes. In R-LDKTX mean age of recipients was 31 +/- 12.5 years. This cohort included 41 men and 25 women whose mean age was 50 +/- 11.1 years. The therapeutic regimen for R-LDKTX included CyA/MMF/prednisone; for NR-LDKTX, FK/MMF/prednisone. Among the recipients of NR grafts the mean recipient age was 51 +/- 8.5 years. This cohort included 23 men and 6 women whose donor mean age was 50 +/- 8.8 years. The mean HLA mismatch among R-LDKTX (2.3) was significantly less than that in the NR-LDKTX cohort (3.51). RESULTS At a mean follow-up of 35 months, 94.7% of grafts were functioning. DGF was seen in only one recipient (1%). Three grafts were lost due to acute (R) or chronic (NR) rejection or to multiorgan failures. Two recipients died with functioning grafts. Biopsy-proven rejection episodes were observed in 17.2% of NR-LDKTX and 9% of R-LDKTX. In R-LDKTX 50% of rejection episodes were corticoid-sensitive, while 33% needed ATG, and 16% were treated by a switch to FK. In NR-LDKTX 20% of rejections were corticoid-sensitive, 40% needed ATG, and 40% were treated with rapamycin rescue therapy. CONCLUSION Although HLA mismatching is significantly different between R- and NR-LDKTX, no difference in outcome was observed, which may be due to the specific therapeutic regimen and short CIT.

Abstract
BACKGROUND With living donation, in addition to the medical risk, the financial risk for the donor is essential, especially in case of complications that potentially can led to disability and loss of work. We report the experiences of those who have donated a kidney in our transplant center. METHODS We contacted 80 donors who donated a kidney at least 6 months prior to evaluation: 72% answered 33 questions. [mean age: 54 +/- 10 (33-75) years; 69% living related, 31% unrelated]. RESULTS Of the 80 donors contacted, 91% (53) reported to have no financial expenses due to donation; 9% (5) had expenses, but only few of them clarified exact amount. One donor had to borrow money to cover the lack when he was unable to perform his job. Another claimed the disparity between normal salary and payment from insurance company as a financial expense. Evaluation procedure prior to donation was organized variously: some donors were on holiday while evaluated, some officially were ill, others had to take off some days without payment. None of the donors lost his or her job due to donation. CONCLUSION The financial risk of living donation is theoretically well covered by different insurances. However, some of the donors had to cover some expenses by themselves. Fortunately, so far in our center no major complications occurred and all donors went home in good health after donation. If costs are covered when a healthy donor loses his or her ability to work due to donation remains unclear since no donor has experienced this problem.

Abstract
Ureteral necrosis after renal transplantation is often the result of impaired perfusion due to loss of donor polar arteries. A way of preserving polar arteries is their anastomosis with the A. epigastrica inferior. In three cases (aged 49-, 58-, and 63 years), 9.3 % of 33 living donors, we detected donor polar arteries on both sides, and anastomosed the polar artery to the A. epigastrica inferior with microsurgical methods. Intraoperatively, the flow was measured by flowmeter, in the postoperative course duplexsonography and MR-angiography was performed. In all three cases we noted a bluish, ischemic parenchym mass of 10-25 % of the kidney and ureter. It recovered immediately, however, after the polar artery had been reconstructed. Intraoperative measurement showed a high flow on the polar- and the main renal artery. Duplexsonography and MR-angiography documented a good flow on the A. epigastrica anastomosis. There have been no signs of ureteral problems at all. After a mean follow-up time of 26 months, the mean creatinine level is 1.46 mg/ml. Ureteral necrosis after kidney transplantation is mostly the result of a lack of perfusion of the polar arteries of the lower kidney pole. If arteriosclerotic lesions inhibit an anastomosis with the renal artery, the anastomosis with the A. epigastrica inferior seems to be a useful alternative.

Abstract
Creation of a neovagina to treat vaginal atresia or aplasia in Mayer-Rokitansky-Kuester-Hauser syndrome must always be followed by long-term application of dilators to avoid shrinkage. However, rectoneovaginal fistulas are caused by chronic alteration and consecutive necrosis of the posterior neovaginal wall. We evaluated retrospectively the postoperative outcome of rectal wall and neovaginal reconstruction using a standardized surgical technique in an exclusive collection of women. Eight women with a mean age of 28 years (range 22-31 years) were treated for rectoneovaginal fistulas in our clinic. Preoperatively, proctoscopy, sphincter manometry, endoluminal rectal ultrasonography, and colonoscopy were performed; and regular postoperative follow-up by digital examination and rectoscopy were obligate. The standard surgical procedure via a perineal approach included fistulectomy and closure of the mucosa and rectal wall followed by a levatorplasty. All but one woman had a temporary colostomy. After 2 weeks the patients were allowed to wear vaginal dilators of a smaller size. Within the mean follow-up period of 20 months, reintervention was necessary twice because of late fistula relapse detected by proctoscopy, barium enema, and subjective symptoms. Morbidity was 25% (n = 2) due to secondary superficial wound healing or urinary tract infection. The average time of the hospital stay was 13 days (10-14 days). One patient complained of vaginal shrinkage and underwent local estrogen therapy with a good functional result 3 months later. Proper fistulectomy and surgical reconstruction with interpositioning of well perfused muscle layers achieved good functional outcome with an acceptable number of minor morbidities. Local estrogen treatment is helpful for avoiding scarification and decreasing the neovaginal size.

Abstract
From July 1996 to November 1997 13 patients underwent "two-in-one"-kidney transplantation from marginal donors. Up to now all renal grafts show a stable function measuring an average creatinin of 1.73 mg/dl after an average follow up of 8.2 month. To take the decision between "one-in-one" or "two-in-two" transplantation in marginal donors we developed a specific score. This score needs more evaluation because of the still small amount of patients undergoing double-kidney-transplantation.
