The Roux-en-Y gastric bypass procedure (RYGBP) is in many countries the gold standard for obtaining long-lasting weight reduction and improvement of obesity-related comorbidities. However, performing this operation by standard laparoscopic techniques requires important surgical skills because of the anastomoses involved. The da Vinci surgical robot system(More)
Results of laparoscopic fenestration in patients with a highly symptomatic solitary liver cyst (17 patients) or polycystic liver disease (PLD) (9 patients) were prospectively evaluated in a multicenter practice of general surgeons. Conversion to laparotomy was required in two patients because of inaccessible deep liver cyst in one and a diffuse form of PLD(More)
Adjuvant treatment of patients with colorectal cancer is hampered by a lack of reliable prognostic factors in addition to the clinicopathological staging system. A poorly defined but considerable fraction of Astler-Coller stage B patients will experience tumour recurrence, and some of the stage C patients will probably survive for a prolonged time after(More)
OBJECTIVE To assess the feasibility, safety, and outcome of laparoscopic liver resection for malignant liver tumors. SUMMARY BACKGROUND DATA The precise role of laparoscopy in resection of liver malignancies (hepatocellular carcinoma [HCC] and liver metastases) remains controversial despite an increasing number of publications reporting laparoscopic(More)
OBJECTIVE Mechanisms explaining the relationship in non-alcoholic fatty liver disease (NAFLD), obesity, and insulin resistance are poorly understood. A genetic basis has been suggested. We studied the association between the genes patatin-like phospholipase domain-containing protein 3 (PNPLA3) and apolipoprotein C3 (APOC3) and metabolic and histological(More)
Background: The objective of this study was to compare the efficacy of the da Vinci robotic system using both the three-dimensional view (3D) and two-dimensional (2D) view options with traditional manually assisted laparoscopic techniques in performing standardized exercises. Methods: To evaluate surgical efficiency in the use of robotically assisted and(More)
Although the morphology and development of the zebrafish enteric nervous system have been extensively studied, the precise neurochemical coding of enteric neurons and their proportional enteric distribution are currently not known. By using immunohistochemistry, we determined the proportional expression and coexpression of neurochemical markers in the(More)
Gastric restrictive procedures such as laparoscopic gastric banding or vertical banded gastroplasty show, at longer follow up, more and more failures and complications. This study focuses on the results of Roux-en-Y gastric bypass procedure (RYGBP) done as a re-do procedure, both after a technically failed restrictive procedure or when the restrictive(More)
BACKGROUND Roux-en-Y reconstruction excludes the afferent limb and the biliopancreatic system from conventional endoscopic access. Postoperative problems in these excluded gastrointestinal systems are therefore often dealt with surgically. We investigated the usefulness of the therapeutic double-balloon enteroscope to perform interventional endoscopic(More)
More and more prosthetic materials are being used in the treatment of inguinal hernia. This report deals with some unusual but devastating complications, occurring after preperitoneal mesh implantation. A 56-year old male patient underwent a Stoppa-repair for a bilateral inguinal hernia. Two years postoperatively, a localized abdominal wall abscess was(More)
