Background/aims: In 2006, a TNM system for foregut neuroendocrine tumors has been proposed. Our study aimed to present the management of neuroendocrine tumors of pancreas according to this classification and to highlight some of its limitations.

Methodology: Clinical, biochemical, radiological, surgical and pathological data were retrospectively collected on 22 consecutives patients, who underwent surgery for neuroendocrine tumors of pancreas between November, 1991 and September, 2005.

Background/aims: The postoperative morbidity following pancreaticoduodenectomy (PD) remains very high. Somatostatin or octreotide are indicated in the prevention of pancreatic stump-related complications. The aim of this study is to compare the efficacy of somatostatin and octreotide after PD.

Objective: The aim of the present study was to investigate the role of intraperitoneal microdialysis (IPM) techniques in monitoring the evolution of postoperative critically ill patients requiring urgent laparotomy.

Summary Background Data: Postoperative intraabdominal sepsis is associated with an important degree of morbidity and mortality in acutely ill patients. Early diagnosis is critical to improve outcomes.

Long-term results of organ transplantation are still limited by serious side effects of immunosuppressive drugs. A major issue, therefore, is to elaborate novel therapeutic protocols allowing withdrawal or minimization of immunosuppressive therapy after transplantation. We report on 3 patients prospectively enrolled in an original protocol designed to promote graft acceptance in living donor liver transplantation, using posttransplant conditioning with high doses of antithymocyte globulin followed by injection of donor-derived stem cells.

Background: A new technical tool was developed and introduced into the therapeutic field of videoscopic surgery-robotic telemanipulation surgery. The aim of this study is to investigate in a prospective randomized trial the feasibility of the Nissen procedure using the da Vinci and to evaluate the benefits and the costs of this new technique compared with the conventional laparoscopic approach.

Materials And Methods: Twenty patients with gastro-esophageal reflux disease (GERD) were randomized into laparoscopic Nissen versus robot-assisted Nissen fundoplication.

Background And Aim Of The Study: The induction of transplantation tolerance, defined as the survival of a functioning allograft in the absence of continuing immunosuppressive therapy, would be a major advance. Clinical and experimental data have shown that transplantation tolerance could be induced by pre-transplant myeloconditioning and infusion of donor hematopoietic cells. We investigated the feasibility and safety of a protocol to induce tolerance to HLA mismatched living-donor liver graft by pre-transplant non-myeloablative conditioning followed by donor stem cells (SC) infusion, in patients with advanced liver cancers.

Parasite infections of the digestive tract are a rare cause of acute haemorrhage in Western countries. We report here on a case of acute intestinal bleeding due to Taenia solium infection diagnosed at surgery. A 79-year-old white female patient was admitted to our institution for instable angina and severe anaemia secondary to acute intestinal bleeding.

Background And Objectives: To assess the value of FDG positron emission tomography (PET) for early detection of incomplete tumor destruction after radiofrequency ablation (RFA) for liver metastasis.

Methods: Twenty-eight unresectable liver metastases in 17 patients were treated by RFA. Patients underwent computed tomography (CT) and FDG-PET preoperatively, at 1 week, 1 month, and 3 months postoperatively.

Better tools for predicting the risk of death while awaiting transplantation are urgently needed because organ shortage is increasing the numbers on transplantation waiting lists. The aminopyrine breath test (ABT), model for end-stage liver disease (MELD), and Child-Pugh (C-P) score were compared as predictors of this risk in 137 cirrhotic candidates for liver transplantation. Eighty-three were transplanted within 3 months of registration, 35 others survived, 13 died before transplantation, and 6 were removed from the list.

Background: Increasing numbers of cases and organ shortage justify reconsidering the global therapeutic approach for hepatocelluar carcinoma in cirrhotic patients.

Methods: Recent literature was reviewed, focused on new therapeutic technologies such as radiofrequency.

Results: For small tumors, liver transplantation offers theoretically the best chance for cure.

Purpose: The addition of radiation to adjuvant 5-fluorouracil for the treatment of pancreatic cancer has not yet shown any definite benefit. Gemcitabine (GEM) has potential activity in advanced pancreatic cancer and is a powerful radiosensitizer. We evaluated the feasibility of postoperative administration of GEM alone, followed by concurrent GEM and irradiation (RT) after curative resection for pancreatic adenocarcinoma.

Background: Graft ischemia-reperfusion injury (IRI) resulting from postreperfusion inflammatory reaction remains a major cause of complications after liver transplantation. In this article, the authors investigated the effect of anti-inflammatory cytokine interleukin (IL)-10 on IRI, in a preclinical model of liver transplantation in pigs.

Methods: Donor pigs received IL-10 or saline at the start of liver graft harvesting.

Biliary stones may occur after liver transplantation, mostly in relation with biliary strictures. We describe an unusual case of biliary stone developing 18 years after liver transplantation and biliary-enteric anastomosis for biliary atresia, responsible for an acute cholangitis caused by obstruction of the jejunal loop. Surgical exploration allowed the removal of the stone and did not reveal any enteric stricture.

The aim of this prospective study is to report our experience in the multimodal management of locally advanced esophageal squamous cell carcinoma (LAESC; stage III cTNM), focusing on the results of chemoradiotherapy followed by surgery. These findings were compared to the results of a standard group of patients with locally advanced esophageal carcinoma (LAEC; stage III pTNM) treated in our center with surgery alone. Sixty-one patients with LAESC underwent preoperative chemoradiotherapy (5-fluorouracil + cisplatin) with concomitant 45 Gray radiotherapy in a 5-week course.
