RESUMO

INTRODUCTION: Intestinal duplication is rarely reported in adulthood and often remains undiagnosed until onset of complications. We describe the case of a 39 year old woman who came to our observation for acute abdomen due to a combination of double intestinal duplication (colon and ileum) and an incidental neuroendocrine tumor of the appendix. MATERIALS AND METHODS: A 39 year old woman who was admitted at with upper abdominal pain. Multisliced spiral CT scan showed a cystic lesion suggestive of an inflammed Meckel's diverticulum.The patient was underwent an urgent explorative laparoscopy. The intraoperative findings revealed a cystic lesion of the anti-mesenteric side of transverse colon, apparently dissectable from the bowel and a second lesion with a strongly adherent and unresectable from the anti-mesenteric aspect of the small bowel. A combined appendectomy was also performed. The histological diagnosis was consistent with a typical intestinal duplication for both intestinal lesionsand an incidental 2mm carcinoid tumor was also found in the appendix. The postoperative course was uneventful and the patient was discharged on p.o. day 5. At the presenttime she is well and following a regular oncologic follow-up. DISCUSSION: The rarity of this case is due to the concomitant presence of an incidental, sincronous, appendiceal NET. The elective treatment is surgical resection. CONCLUSION: Intestinal duplication in the adulthood is extremely rare and may either have an acute presentation as acute abdomen or represents an incidental finding of mass. We suggest that, once the diagnosis is suspected patient must undergo surgery.

RESUMO

INTRODUCTION: We report the preliminary results of endolymphatic immunotherapy in patients with inoperable hepatocellular carcinoma (HCC). METHODS: From 2003 to 2005 we enrolled 31 patients with inoperable HCC. The patients underwent monthly endolymphatic injections of 15-30 x 10(6) interleukin-2 (IL-2)-activated peripheral autologous lymphocytes (LAK) and 250 IU of IL-2. Follow-up included blood biochemistry every 3 months and imaging studies every 6 months. To assess therapy efficacy we considered 12 biochemical parameters, vascular invasion or thrombosis, Child-Pugh scoring system, histological grading, lymphadenopathy, viral state, and alpha-fetoprotein. RESULTS: Sixteen patients completed at least 3 cycles, and 10 patients completed more than 6. No clinically significant adverse reactions occurred. Imaging studies showed no significant decrease in tumor mass. However, the survival of patients who completed 12 therapy cycles was significantly higher than survival of patients with fewer than 12 cycles. Both are significantly higher than that of untreated patients. All patients with 12 completed cycles showed an improvement of 9 parameters or more. DISCUSSION: Endolymphatic immunotherapy is safe, easily performed, inexpensive, and effective in terms of survival. This study should encourage future large-scale investigations so as to reach a firmer conclusion and define uniform inclusion criteria.

RESUMO

AIM: To determine whether the physiologically oxygenated arterial blood reversed in the portal system by means of portal vein arterialization (PVA) through an extracorporeal device which we have called L.E.O2.NARDO (Liver Extracorporeal Oxygen. NARDO) is effective in treating swine with subtotal hepatectomy leading to acute liver failure (ALF). METHODS: Ten swine with ALF induced by 85-90% liver resection and five minutes of ischemia-reperfusion injury were randomly divided into two groups: five animals received PVA extracorporeal treatment and five swine were not-treated (control group). Blood was withdrawn from the iliac artery and reversed in the portal venous system. An extracorporeal device was interposed between the outflow and the inflow in order to monitoring the hemodynamic parameters. Each treatment lasted 6 hours. Serum and liver samples were collected in both groups. The survival was assessed at 1 week. RESULTS: The PVA-extracorporeal treatment yielded beneficial effects for subtotal hepatectomy-induced ALF swine with decreased serum ammonia, transaminases and total bilirubin as compared with the untreated group. INR recovered rapidly in the PVA-extracorporeal group remaining significantly lower than in untreated animals. The 7-day survival of PVA-extracorporeal group swine was significantly higher than that of untreated animals, with a statistically significant difference (p<0.05). Four swine in the PVA-extracorporeal group survived at 1 week while none of the swine in the control group were alive at that time; an average time of 144h+/-13h and 24.4h+/-5h was observed in the PVA-extracorporeal and control groups, respectively. CONCLUSIONS: Arterial blood supply in the portal system through the extracorporeal device is easily applicable, efficacious, safe and may represent a novel approach for ALF swine induced by subtotal liver resection.

RESUMO

AIM: Kidney transplantation with ureteral duplication may represent a doubled risk factor in terms of ureteral stenosis or necrosis with urinary leakage usually from the site of ureteroneocystostomy. The incidence of complete duplication is very low at 0.19%. We report a kidney with ureteral duplication in the specific setting of multiorgan transplantation since it could be considered an adjunctive risk factor for urological complications. METHODS: The recipient was a 67-year old man, suffering from terminal renal insufficiency. He was also affected by HCV-related cirrhosis. The patient had been waiting for the combined transplantation for 27 months and in the last two months his hepatic function dramatically worsened. The donor was a 53-year old man who died of non-traumatic subarachnoid hemorrhage. Good HLA compatibility was observed between donor and recipient. During harvest both kidneys presented a complete ureteral duplication. So the ureters were freed together with a wide cuff of periureteral tissue and dissected distally. No vascular abnormalities were noted during the removal of either kidney. The grafts were flushed with University of Wisconsin solution and stored in the same solution. RESULTS: The liver was reperfused after 9 hours of cold ischemia. Subsequently the kidney was vascularized after 15 hours of cold ischemia. Urine production occurred immediately after revascularization. Two separated ureteroneocystostomies with a single antireflux technique were performed. Cyclosporine and steroids were given. Post-operative course was uneventful and liver and kidney function were normal. The 7-day cystography was normal. The 6, 12, 24 month ultrasonographies showed no signs of hydronephrosis or hydroureter. After 28 months renal cancer was diagnosed and the patient underwent a right nephrectomy. The liver-kidney recipient had excellent hepatic and renal function for 84.7 months. He died of malignancy from de novo tumor. CONCLUSIONS: On the basis of this experience, a kidney with an ureteral duplication, while rare, can be satisfactorily used also in combined liver-kidney transplantation.

RESUMO

AIM: Double-kidney transplantation is performed using organs from marginal donors with a histological score not suitable for single kidney transplantation. The aim of the study is to verify the results obtained with double-kidney transplantation in terms of graft and patient survival and complications. METHODS: Between September 2001 and September 2004, 16 double-kidney transplantations were performed in our center. The kidneys were all perfused with Celsior solution and the mean cold ischemia time was 17.6+/-2.7 hours. In all cases a pre-transplant kidney biopsy was performed to evaluate the damage. Immunosuppression was tacrolimus based for all patients. RESULTS: Eight patients had good renal postoperative function while the other eight had acute tubular necrosis. Two of the patients who had severe acute tubular necrosis never recovered renal function. There was only one episode of acute rejection, while the incidence of urinary complications was 31.2%; there were two surgical revisions for intestinal perforation. The graft and recipient survival was 78.1% and 100% and 78.1% and 93.7% at 3 and 36 months. CONCLUSIONS: Double-kidney transplantation is a safe way to face the organ shortage. Moreover the score used in this study is useful to determine whether a kidney should be refused or suitable for single or dual-kidney transplantation. The results of our initial experience are encouraging, but this series is too small in number to consent a conclusive statement.

RESUMO

INTRODUCTION: Hyperoxygenation of the liver has been suggested to improve its regenerative capacity. Thus, this study sought to determine whether an additional supply of oxygenated blood delivered by portal vein arterialization (PVA) was protective against acute liver failure induced by hepatectomy. METHODS: Sprague-Dawley rats (six per each group) were divided to either undergo PVA or be untreated after extended hepatectomy. Liver injury was evaluated by the serum alanine aminotransferase (ALT) levels. Hepatocyte regeneration was assessed by calculating the mitotic index and bromodeoxyuridine staining. The 10-day survival was assessed in separate experimental groups. RESULTS: The pO(2) in portal blood increased significantly following PVA. Serum ALT levels were significantly reduced in arterialized versus nonarterialized rats. PVA promotes liver regeneration. Finally, PVA significantly improved host survival compared to the controls: 90% versus 30%, respectively. CONCLUSION: These data suggested that an additional supply of arterial oxygenated blood through PVA promoted a rapid regeneration, leading to a faster restoration of liver mass after partial hepatectomy in rats. Thus, PVA may represent a novel tool to optimize hepatocyte regeneration.

RESUMO

INTRODUCTION: Optimization of the conditions for regeneration of the native diseased liver is a major goal in patients with acute liver failure. This study sought to determine whether portal vein arterialization (PVA), which increases the oxygen supply to the liver, was protective in a rat model of liver failure. METHODS: At 24 hours after CCl(4) intoxication, Sprague-Dawley rats (six per group) were assigned to receive PVA or as controls. We determined blood tests, histology, and 10-day survivals. Hepatocyte regeneration was assessed by the mitotic index and bromodeoxyuridine (BrdU) incorporation. RESULTS: Serum transaminases were significantly lower in PVA-treated rats than in control animals: liver necrosis resolved rapidly after PVA. The BrdU staining and mitotic index were severalfold higher among PVA-treated than in untreated rats. Survival was 100% among rats with PVA and 40% in untreated animals (P < .01). CONCLUSIONS: PVA led to resolution of CCl(4)-induced massive liver necrosis in the rat. This effect was probably mediated by activation of rapid and extensive hepatocyte regeneration. PVA might provide a novel, alternative approach to treat acute liver failure.

RESUMO

AIM: To determine whether the increase of oxygen supply in the portal system by a liver extracorporeal (L.E.O.NARDO) device is effective in treating swine with subtotal hepatectomy leading to acute liver failure (ALF). METHODS: Eight swine with ALF induced by 85% to 90% liver resection and 5 minutes of ischemia-reperfusion injury were randomly divided into two groups: four animals received L.E.O.NARDO treatment and four swine were not treated (control group). Blood was withdrawn from the iliac artery and reversed in the portal venous system. An extracorporeal device was interposed between the outflow and the inflow in order to monitor the hemodynamic parameters. Each treatment lasted 6 hours. Serum and liver samples were collected in both groups. The survival was assessed at 1 week. RESULTS: L.E.O.NARDO treatment yielded beneficial effects for subtotal hepatectomy-induced ALF in swine with decreased serum transaminases as compared with the untreated group. International normalized ratio recovered rapidly in the L.E.O.NARDO group, remaining significantly lower than in untreated animals. The 7-day survival of L.E.O.NARDO group swine was significantly higher than that of untreated animals, with a significant difference. Three swine in the L.E.O.NARDO group survived 1 week while none of the swine in the control group were alive at that time. CONCLUSIONS: Oxygen supply in the portal vein through the L.E.O.NARDO device is easily applicable, efficacious, and safe and may represent a novel approach for ALF in swine induced by subtotal liver resection.

RESUMO

Survival rates of patients with acute liver failure (ALF) without transplantation are poor. However, many of them die awaiting a transplant because of the donor organ shortage. Supporting these patients until an organ becomes available or until their own liver is able to regenerate itself thus avoiding transplantation is a major goal in their multidisciplinary treatment. Animal experimental studies have shown that portal vein arterialization (PVA) enhances the regenerative capacity of hepatocytes by increasing the oxygen supply to the liver after extended hepatectomy or in toxin-induced ALF models. Furthermore, we have reported the application of PVA in patients with ALF. We herein have described the technical aspects of the PVA procedure both in preclinical models and in man.

RESUMO

AIM: The aim of present study was to assess the effect of Celsior as compared with University of Wisconsin (UW) solution on immediate and long-term function of kidney transplants harvested from elderly donors. METHODS: A prospective multicenter randomized study was designed to evaluate the efficacy of Celsior versus UW solution for the clinical preservation of the kidney. Fifty renal transplants were performed from donors over 60 years old. Twenty-five kidneys were stored in Celsior and 25 in UW solution. The groups were comparable with regard to donor and recipient characteristics. Renal function outcomes were compared by evaluating delayed graft function rates, daily urinary output, as well as the evolution of mean serum creatinine at 1, 3, 5, 7, and 15 days. RESULTS: The warm ischemia time was 42.4 +/- 11 minutes among Celsior vs 46.9 +/- 17.9 minutes in the UW cohort (P = NS). The cold ischemia time was 18 +/- 4.5 hours in Celsior and 19 +/- 6.5 hours in UW (P = NS). Delayed graft function occurred in 48% of the Celsior group and in 52% of the UW group (P = NS). Mean serum creatinine levels and mean daily urinary output were also similar. One- and 5-year graft survivals of kidneys preserved with Celsior were 91.8% and 79.3% compared with 96% and 87.4% for UW without any significant statistical difference. CONCLUSIONS: Our data show that the preservation of kidneys from elderly donors in Celsior solution is equivalent to that of UW solution.

RESUMO

AIM: We report a series of patients who underwent combined heart-kidney transplantation (CHKT) and combines liver-kidney transplantation (CLKT) at a single center. METHODS: From January 1997 to October 2004, 13 CLKT and 2 CHKT were performed. The CLKT indications were as follows: polycystic disease (2), kidney polycystic disease associated with Caroli (1) and cirrhosis-hepatitis C virus (HCVs) (1), chronic glomerulonephritis with cirrhosis-HCV (4), and other diseases (5). From December 2003 to October 2004, 2 patients underwent CHKT for idiopathic cardiomyopathy plus glomerulonephritis and ischemic cardiomyopathy associated with vascular nephritis. RESULTS: In the CLKT group, 1 patient had acute rejection involving both liver and kidney grafts, whereas 1 patient had liver rejection and another 1 had kidney rejection alone. Of the 13 patients, 10 are alive with a mean survival of 583 days (range, 36-2688 days); 2 patients died within 1 month of transplantation (both with polycystic disease) due to ARDS and MOF. Another patient died 6 years and 9 months after CLKT of metastasis from a de novo tumor. In the CHKT group, no patient suffered heart-kidney rejection. They are all alive at 333 and 116 days, with heart and kidney allografts functioning well. CONCLUSION: In the CLKT group, the worst results were for patients with polycystic disease, in whom a more rigorous selection is necessary because of greater technical difficulties. For the remaining patients we had acceptable complications and excellent long-term results. In selected cases, CHKT can provide long-term graft function and patient survival. Our experience indicates that end-stage kidney failure combined with liver or heart failure does not necessarily preclude dual-organ transplantation.

RESUMO

In our initial experience of kidney transplantation, we performed an extravesical uretero-cystostomy (U-C), but in 1997 we shifted to a uretero-ureterostomy (U-U) with the aim of reducing early and late urological complications. A data base was constructed to compare the incidence, donor and recipient risk factors, treatments, and outcomes of urological complications with the two techniques. From 1990 to the end of July 2004, 894 kidney transplants included 43 from living donors and 851 from cadaveric donors with 804 first and 47 second transplants. We observed 48 urinary fistulas (5.4%): 45 were successfully repaired and three were treated with a ureteral stent with two good results; and one failed at a late operation. We had 26 early stenoses (2.9%), all of which were successfully treated: 16 with surgery and 10 with a stent. Donor and recipient risk factors for fistula and early stenosis did not reach statistical significance, confirming the technical etiology of these complications. There were only six cases of late ureteral stenosis in patients operated after 1990, and in eight cases of U-C we observed vesico ureteral reflux. There were 88 urological complications, with only one kidney lost. The shift from U-C to U-U did not change the incidence of urological complications, but with U-U we observed a significant decrease in the number of postoperative urinary infections, an easier possibility to resolve ureteral stenosis with endourology and no reflux. It is now our first choice with a normal ureter.

RESUMO

Survival rates of patients with acute liver failure (ALF) without transplantation are poor. Supporting these patients until an organ becomes available or until their own liver is able to regenerate itself, avoiding transplantation, is a major goal in the treatment of ALF. We report our clinical experience of portal vein arterialization in one case of massive liver necrosis after liver transplantation and in two patients with ALF caused by idiosyncratic drug reaction and mushroom intoxication. Portal vein arterialization, at least in two cases, was a turning point in the course of the disease since a close temporal association between surgery and clinical improvement was clearly evident. We believe that this novel approach, which should promote liver regeneration by providing an additional oxygen supply to the liver, may disclose a new possibility in the treatment of ALF and prompt new clinical and experimental research.

RESUMO

INTRODUCTION: A prospective, randomized, multicenter, open clinical trial was performed to compare the main liver function tests, postoperative complications, and early graft and patient survival of recipients transplanted with livers preserved in Celsior (CEL) versus histidine tryptophan ketoglutarate (HTK) solutions. METHODS: We analyzed the data from a single center. Forty livers randomized to CEL (n = 20) or HTK (n = 20) preservation solution were perfused in situ via the aorta and portal vein (CEL, 30 mL/kg via portal vein and 60 mL/kg via aorta; and HTK solution, 30 mL/kg via portal vein and 120 mL/kg via aorta). RESULTS: The groups were comparable with regard to donor, graft, and recipient characteristics. The mean cold ischemia time was 458 minutes (range: 203-667 minutes) in CEL and 450 (range: 310-684 minutes) in HTK. The incidence of initial poor function and primary nonfunction in CEL and HTK were (0 vs 1) and (0 vs 1), respectively. No differences were observed for acute rejection. No vascular or biliary complications were reported in either group. The 3-month graft and patient survival rates were 95% and 95% in CEL and 80% and 90% in HTK. The 12-month graft and patient survival rates were 90% and 90% in CEL and 75% and 85% in HTK. CONCLUSIONS: To our knowledge, this is the first report comparing CEL and HTK preservation solutions in clinical liver preservation. Although a greater 1-year graft and patient survival was observed in the CEL group, a definitive evaluation comparing CEL and HTK solutions in clinical preservation must await completion of the trial.

RESUMO

Although octogenarian livers have been transplanted successfully in elective settings, their safety in the case of fulminant hepatic failure has not yet been reported. From November 1998 to June 2003, we transplanted 3 livers from 80-, 82-, and 86-year-old donors. The donors were hemodynamically stable with an intensive care unit stay ranging from 24-48 hours. Cold ischemia time was from 260 minutes to 526 minutes. Mild macrosteatosis was present in 2 donors. Donor and recipient characteristics as well as posttransplantation evolution were evaluated. Two cases had uneventful courses and all recipients are well at 39, 21, and 5 months, respectively. The second recipient underwent retransplantation at 15 days due to technical complications. Livers from octogenarian donors may be safely used in an emergency to save patients. Age does not represent a limit for individually assessed and highly selected donors.

RESUMO

INTRODUCTION: To evaluate the influence of pretransplantation recipient and donor prognostic factors on graft-patient survival. MATERIALS AND METHODS: Between April 1986 and June 2003, 40 liver transplantation (LT) procedures to treat fulminant hepatic failure were performed (5.7%). Twenty-one pre-LT recipient and donor variables were retrospectively considered for analysis. RESULTS: The indications for LT were hyperacute (62.5%), acute (35%), and subacute hepatic failure (2.5%). Glasgow Coma Scale scores ranged from <5 in 22 patients to > or =5 in 18 patients. The causes were hepatitis B (n = 21), unknown (n = 10), Amanita phalloides (n = 5), and other (n = 4). The 1-year graft and patient survival rates were 48.3% and 61.3%, respectively. Perioperative and late mortality was 27.5% and 22.5%. The only variable statistically significant for graft survival was waiting list time for LT <48 hours (P = .05). DISCUSSION: Liver transplantation is the best treatment for fulminant hepatic failure, with a 1-year patient survival rate of 61.3%. The short waiting list time has an important role in outcome.

RESUMO

INTRODUCTION: Although portal vein thrombosis (PVT) is no longer considered a contraindication for liver transplantation (OLT), it is still considered a high risk because of the complexity of the surgical procedure. The aim of this study was to evaluate the impact of PVT in the recipient during OLT on intra- and perioperative management and outcome. PATIENTS AND METHODS: Between April 1986 and October 2003, 721 primary OLT included 64 patients (8.8%) with PVT. The underlying liver disease was postnecrotic cirrhosis in most cases (n = 37). Intraoperative (length of surgery, packed red blood cells (PRBC) transfusion requirements, ischemia time, complications) and postoperative parameters (ICU stay and hospitalization time, complications, actuarial graft and patient survival at 1 month and 1 and 5 years) were compared with a control group of patients submitted to OLT without PVT (n = 657). RESULTS: Portal flow was reestablished in 56 patients with thromboendovenectomy, in seven patients with a venous graft from the superior mesenteric vein, and with cavoportal hemitransposition in one case. The average ICU and hospital stay as well as the 1-month and 1- and 5-year patient survivals were not significantly different in the PVT versus the control group. We observed slightly more PRBC transfusions and longer surgery procedures in the PVT group. CONCLUSIONS: Our experience suggests that thromboendovenectomy is the procedure of choice for PVT. The results are good in terms of survival rates and postoperative complications, although the presence of PVT may lead to more technical problems during surgery.

RESUMO

INTRODUCTION: We aimed to analyze the influence of intraoperative blood transfusion on postoperative complications and survival and to identify the preoperative variables associated with greater intraoperative bleeding. MATERIALS AND METHODS: Thirty-one elective liver transplantations (OLT) without blood transfusion performed between 1986 and 2002 (group 1) were compared with 62 patients (group 2) who underwent elective OLT with intraoperative transfusion after matching for gender, disease severity, and chronology. RESULTS: The hemoglobin and hematocrit values were significantly greater in group 1 compared to group 2. No significant differences were reported for the other parameters. In particular, the type of surgical technique had no influence on the blood requirement. As expected the nontransfused patients received less autologous packed red blood cells compared with the transfused patients. No differences were observed in either group for mean CIT, ICU and hospital stay, or acute rejection. A significant difference was observed in the number of postoperative infectious episodes, which was higher in group 2 (28 vs 5, P = .01). Graft and patient survivals at 3 months and 5 years did not differ significantly between groups. CONCLUSIONS: OLT without blood transfusion may be achieved in the presence of good recipient conditions. Lower preoperative hemoglobin and hematocrit values were associated with greater intraoperative transfusions.

RESUMO

INTRODUCTION: The shortage of donors has made it necessary to consider older subjects, those with mild or moderate steatosis, and those who are HBcAb- or hepatitis C virus (HCV)-positive as marginal donors. MATERIALS AND METHODS: From April 1986 to January 2002, 690 orthotopic liver transplantations (OLTs) were performed in 603 patients. In this series we used 68 donors older than 70 years, 51 with steatosis (38 mild, 12 moderate, and 1 severe), 44 were HBcAb-positive and 6 were HCV-positive. RESULTS: Of 68 grafts from donors older than 70 years, 65 were used as a first OLT. These grafts showed 3 PNF, 11 arterial complications, 12 re-OLTs, and 14 deaths with graft survival of 72.3% and 61.34% at 1 and 3 years, respectively. All patients who received the other 3 grafts, which were used for re-OLT, died between postoperative day 21 and 720. Among the 51 grafts with steatosis, we observed 2 PNF of those within the mild steatosis group and graft survival rates of 76.8% and 70.9% at 1 and 3 years, respectively. Forty-four grafts from HBcAb-positive subjects were used in 18 HBsAg-negative and 26 HBsAg-positive recipients. Among the untreated patient group, 1 patient demonstrated hepatitis B virus (HBV) reinfection and 1 patient had de-novo HBV. No reinfection or de novo infections were observed in the 13 patients treated with immunoglobulin or in the 19 patients treated with lamivudine plus immunoglobulin, or in the only patient treated with lamivudine. Graft survival rates were 64.1% and 54.7% at 1 and 3 years, respectively. Among who received 6 patients transplants from HCV-positive donors, we observed 1 recurrence of chronic hepatitis, 1 re-OLT for hepatic vein stenosis, and 1 PNF. CONCLUSION: Old donors, those with moderate steatosis, or those who are HBcAb- and HCV-positive can be safely used in selected recipients to reduce waiting list mortality.
