PURPOSE: Nowadays laparoscopic colorectal surgery has demonstrated its advantages, including reduced postoperative pain, decreased duration of ileus, and shorter hospital stay. Few studies report results of laparoscopic surgery in complicated diverticulitis. This study was designed to analyze the results of laparoscopic sigmoidectomy in patients with fistulized sigmoiditis. METHODS: The authors retrospectively reviewed 16 patients who had laparoscopic sigmoidectomy for fistulized diverticulitis between 1992 and 2003 in a series of 247 laparoscopic colectomies. Eleven patients presented with colovesical, four with colovaginal, and one with colocutaneous fistulas; all were caused by sigmoiditis. The procedure always consisted of celioscopic sigmoidectomy with stapled transanal suture and, when indicated, closure of the cystic or vaginal fistula orifice. RESULTS: Mean age was 60 (range, 39-78) years. Mean number of episodes of diverticulitis before operation was three (range, 1-5). Mean time between the last episode and operation was 46 (range, 2-250) weeks. In our first three years of experience, three cases (18.7 percent) were converted to laparotomy. Reasons for conversion were the necessity for intestinal resection, splenectomy, and a wound of the anterior rectum. The mean operative time was 172 (range, 100-280) minutes. Mean hospital stay was 5.7 (range, 3-12) days. There was no mortality. Postoperative morbidity (2 patients, 12.5 percent) consisted of one pulmonary infection and one splenectomy. Long-term follow-up revealed no recurrence of diverticulitis and one incisional hernia. CONCLUSIONS: In experienced hands, laparoscopic sigmoidectomy may be a safe and effective procedure for fistulized sigmoiditis. [less ▲]

Until now, Belgium has been considered as a low-risk country for alveolar echinococcosis. However it was recently demonstrated by necropsy series that, in some parts of southern Belgium (Wallonia), up to 51% of the red foxes (Vulpes vulpes) may be infected by E. multilocaris. The authors, working in a university hospital in southern Belgium, described in 2002 the first autoctuthonous Belgian case of hepatic alveolar echinococcosis. More importantly, in 2004, they diagnosed three other patients with alveolar echinococcosis. One underwent surgical resection, but two others had bilateral pulmonary involvement at time of definite diagnosis. Palliative albendazole therapy was initiated. These patients had been diagnosed with hepatic mass from unknown origin for several months. The previous experience with the first case allowed the authors to consider and to confirm alveolar echinococcosis diagnosis, made by pathology and/or serological tests and imaging. These four patients with alveolar echinococcosis were living either in the Liege or the Luxembourg province. Considering the high prevalence of E. multilocaris infection of red foxes and the recent increase of the fox population due to rabies vaccination in southern Belgium, and also the presence of E. multilocaris infection of red foxes in northern Belgium, it is likely that not only Wallonia, but also maybe the whole Belgium, may face endemic alveolar echinococcosis in the next years.

The etiological mechanisms of brain edema in fulminant hepatic failure are incompletely understood. In a surgical model of fulminant hepatic failure in the rat, we tested whether oxidative stress may be involved in the early steps of brain edema. Moreover, we took advantage of this model to determine if oxidative stress may be involved in the hepatocyte dysfunction observed in the setting of fulminant hepatic failure. Oxidative stress was evaluated by measurement of tissue ascorbic acid in the brain and liver of rats at 6 hours after induction of fulminant hepatic failure versus in control or partially hepatectomized rats. After 6 hours, the level of ascorbic acid was not different in the brain tissue of the various groups, indicating no oxidative stress. The liver showed a significant decrease in ascorbic acid levels, both in ischemic and nonischemic liver tissue, suggesting that oxidative stress might be involved in the failure of liver regeneration in fulminant hepatic failure. In this rat model no oxidative stress was demonstrated in the brain during the early phase of fulminant liver failure. [less ▲]

The authors report the case of a 55 yr-old woman suffering from Crohn's disease since 31 years with stricture and fistulas developed in the ileocolic junction and anorectal portion. Long-standing anorectal fistulas and stricture led to adenocarcinoma and finally fistulisation in the vagina. Diagnosis was made by perineal examination with biopsies under general anaesthesia. Treatment was first posterior pelvectomy with resection of the anterior wall of vagina. Secondarily, radiochemotherapy was administrated. The authors discuss the incidence and risk factors of carcinoma in Crohn's disease with chronic fistulas. [less ▲]

Pancreas transplantation has now become an established option in the treatment of diabetic complications. It normalizes glucose metabolism, prevents, stabilizes and improves the evolution of diabetes-associated lesions. Improvements in surgical procedure and in immunosuppression have better defined its indications. Combined kidney-pancreas transplantation appears today as the best treatment for the diabetic patient with end stage renal disease. Isolated pancreas transplantation is reserved to non-uremic patients with severe diabetic complications or with hyperlabile glycaemic control and severe impairment of quality of life. [less ▲]

BACKGROUND: Comparison studies of calcineurin inhibitors as cornerstone immunosuppressants in renal transplantation have demonstrated that tacrolimus consistently reduces acute rejection rates and, in some studies, also improves long-term renal outcome in comparison to cyclosporin A (CsA). The aim of the present 2 year follow-up of the European Tacrolimus vs Cyclosporin A Microemulsion Renal Transplantation Study was to investigate long-term clinical outcome in terms of rate of acute rejection, graft and patient survival and graft function. METHODS: The European Tacrolimus vs Cyclosporin A Microemulsion Renal Transplantation Study was a randomized, comparative 6 month trial of the calcineurin inhibitors tacrolimus and CsA in combination with both azathioprine and steroids. The intent-to-treat population (ITT) consisted of 286 patients in the tacrolimus arm and 271 in the CsA microemulsion (CsA-ME) arm. Whereas whole blood level targets were 10-20 and 5-15 ng/ml for tacrolimus and 100-400 and 100-200 ng/ml for CsA during months 0-3 and 4-6, respectively, during the investigator-driven follow-up after termination of the main study (months 7-24) no specific calcineurin inhibitor target levels were required. Follow-up data were collected at 2 years post-transplantation from 237 (82.9% of the ITT population) patients who received tacrolimus and 222 (81.9% of the ITT population) patients who received CsA-ME. RESULTS: Calculated on ITT populations, mortality (2.0% vs 3.3%; P<0.05 in Kaplan-Meier analysis) was lower, but rate of graft loss (9.3% vs 11.2%; P = 0.12 in Kaplan-Meier analysis) was not significantly different after 2 years with tacrolimus- vs CsA-ME-based immunosuppression. Biopsy-proven acute rejection was significantly lower (19.6%) with tacrolimus than with CsA-ME (37.3%) during months 0-6 (P<0.0001), but was not significantly different during months 7-12 and 13-24 of follow-up (1.7% and 0.8% with tacrolimus and 4.7% and 0.9% with CsA-ME, respectively). A composite endpoint consisting of graft loss, patient death and biopsy-proven acute rejection occurred significantly more frequently in CsA-ME patients than in tacrolimus patients (42.8% vs 25.9%; P<0.001) during 24 months follow-up. Renal function 2 years post-transplant, measured by serum creatinine concentrations, was significantly better in tacrolimus-based compared with CsA-ME-based immunosuppression (136.9 vs 161.6 micromol/l; P<0.01). Cornerstone immunosuppression remained unchanged in 82.5% and 66.2% of patients treated with tacrolimus and CsA-ME, respectively. At 2 years, more patients in the tacrolimus arm were off steroids and received calcineurin inhibitor monotherapy, and fewer tacrolimus patients remained on a triple immunosuppressive regimen. The cardiovascular risk profile was affected favourably in the tacrolimus arm, with lower cholesterol and triglyceride concentrations (despite less use of cholesterol-lowering drugs); no significant difference in requirement for antidiabetic medication was noted. CONCLUSIONS: The 2 year study results confirm that tacrolimus is a highly efficacious cornerstone immunosuppressant in kidney transplantation. Tacrolimus-based immunosuppression may induce long-term benefits with regard to graft function and graft survival. The overall side-effect profile is considered to be favourable. [less ▲]

The authors report the case of a patient aged 60-year-old who survived ulcerative colitis complicated by toxic megacolon and disseminated intravascular coagulation. This patient was not known for this ulcerative colitis and was first hospitalised for a suspicion of diverticulitis. The admission symptoms were fever, abdominal pain and bloody diarrhoea. The evolution was defavorable under antibiotics and sulfasalazine. The patient was readmitted 5 days after he left hospital, and the diagnosis of UC was based on colon biopsy made during the first hospitalisation. A treatment with methylprednisolone was started and the patient worsened day by day with apparition of toxic megacolon and disseminated intravascular coagulation. Subtotal colectomy was performed for degradation of general status and coagulation factors. Pathological findings confirmed ulcerative colitis with toxic megacolon. Cytomegalovirus inclusions were demonstrated on the colonic specimen and confirmed by PCR. In this report the authors discuss the etiology of toxic megacolon and disseminated intravascular coagulation in ulcerative colitis surinfected by cytomegalovirus. Mortality of these pathologies is high necessitating rapid diagnosis of cytomegalovirus infection by sigmoid biopsy. Management requires immunosupression interruption and ganciclovir therapy, or surgery in unsuccessful medical treatment. [less ▲]

Introduction. There is some controversy on the necessity of venous reconstruction of the right paramedian sector (segments V and VIII) during right lobe living related liver transplantation. In this report we describe the evolution of posttransplant graft function in five consecutive right lobe recipients without specific drainage of the right paramedian sector. Material and methods. The technique of common right hepatectomy for right lobe graft harvesting and transplantation did not include the middle hepatic vein in the graft. The mean total ischemic time was 51 minutes (ranges: 35 to 64 minutes). The mean graft to recipient weight ratio was 1.35% +/- 0.15%. No patient developed small-for-size syndrome. Results. All patients showed a rise in transaminases with a maximum at postoperative day 2 (mean aspartate aminotransferase: 1067 +/- 432 IU/mL). Liver function improved rapidly, with coagulation normalized at postoperative day 5. Bilirubin decreased progressively to normalize in three patients at postoperative day 14. Ultrasonography and computed tomography demonstrated that the paramedian sector of the right liver was congested, a state that was temporary with normalization of the liver tests and congestion disappeared at follow-up. No complication was linked to congestion. Discussion. This series showed that in right lobe liver transplantation with a relatively large-size graft, reconstruction of the hepatic veins of the paramedian sector may not be necessary despite the induction of some degree of venous congestion. In smaller grafts, this congestion might be avoided by reconstruction of the large veins draining segments V and VIII. [less ▲]

Liver transplantation is a major surgical procedure usually requiring large amount of blood products (red cells, platelets, fresh-frozen plasma). We developed a multidisciplinary transfusion-free protocol for liver transplantation in Jehovah's witnesses who refuse the use of blood products but accept organ transplantation. Between September 1998 and November 2004, 9 of 29 Jehovah's witnesses evaluated for liver transplantation were transplanted after medical preparation. None of these patients received any blood product during the surgical procedure. This experience may be beneficial for the entire liver transplantation population, as excessive transfusion has been linked to increased morbidity and mortality in liver transplantation. [less ▲]

Living related liver transplantation (LRLT) in adult recipients has been recently developed to overcome the organ donor shortage, but LRLT leaves the healthy donors at risk of serious post-operative complications, or even death. The aim of this paper is to report the prospective evaluation of the initial experience of adult LRLT at the University of Liege. From March 2002 till March 2003, in a consecutive series of 35 adult liver transplantations, five recipients (mean age : 51 years) underwent LRLT, including one retransplantation. Indications for transplantation were autoimmune hepatitis, hepatitis B virus related cirrhosis with hepatocarcinoma (two cases), hepatitis C virus related cirrhosis with hepatocarcinoma, and ischemic intrahepatic bile duct necrosis 10 years after primary liver transplantation. Mean age of the donors was 34 years (range : 21-53 years). All donation cases were intra familial at first degree. The right lobe was used as a graft in four cases and the left lobe in one case. All right lobe donors developed transient hyperbilirubinemia and hypocoagulation for 4 to 6 days. No severe complication (transfusion, bile duct fistula, reintervention, rehospitalization) nor significant long-term sequelae were observed in the donors. In the recipients, graft function was immediate, and there was no small-for-size syndrome. One recipient developed biliary fistula treated by reoperation. One recipient died from invasive aspergillosis 11 days after the procedure. The four other recipients were alive without recurrence of the disease at follow-up. This report confirmed that LRLT may be a valuable alternative to cadaveric liver transplantation in the era of organ donor shortage. However, even if there was no severe complication for the donors in our preliminary experience, LRLT puts healthy living donors at risk of significant morbidity and even death. [less ▲]

AIM: Under clinical conditions small bowel mucosa is stored without any contact between the mucosa and the preservation solution. We evaluated the impact of luminal contact with University of Wisconsin solution (UW) on the structural quality of small bowel preservation. METHODS: Segments of ileum harvested from stable multi-organ donors were flushed with UW. For each donor, ileal segments were placed in UW without any contact between the mucosa and the preservation solution (group A), as is practiced in clinical conditions. Adjacent segments were cut on their antimesenteric side and placed in UW so that their mucosa was widely in contact with the solution (group B). The grafts preserved in ice were removed from the preservation fluid at different times (0, 3, 6, or 12 hours). Tissues were studied by optical microscopy after H [less ▲]
