OBJECTIVE Acute cholecystitis is a common disease, and laparoscopic surgery is the standard of care. BACKGROUND Optimal timing of surgery for acute cholecystitis remains controversial: either early surgery shortly after hospital admission or delayed elective surgery after a conservative treatment with antibiotics. METHODS The ACDC ("Acute(More)
BACKGROUND Laparoscopic surgery has potential theoretical advantages over open surgery in reducing the rate of adhesion formation, but very few comparative studies are available to prove this. METHODS A literature search was performed within Medline and Cochrane databases using the key words: adhesion*, adhesiolysis, laparoscop*, laparotomy, open surgery.(More)
Concepts in "fast-track" surgery, which provide optimal perioperative care, have been proven to significantly reduce complication rates and decrease hospital stay. This study explores whether fast-track concepts can also be safely applied and improve the outcomes of major pancreatic resections. Perioperative data from 255 consecutive patients, who underwent(More)
BACKGROUND Although providing excellent outcome results, laparoscopy also induces particular pathophysiological changes in response to pneumoperitoneum. Knowledge of the pathophysiology of a CO(2) pneumoperitoneum can help minimize complications while profiting from the benefits of laparoscopic surgery without concerns about its safety. METHODS A review(More)
BACKGROUND/AIMS In addition to the primarily affected small bowel, intestinal ischemia and reperfusion (IIR) also leads to a marked decrease in hepatic microcirculation. The aim was to determine the potentially protective effect of the vasoactive hormones vasoactive intestinal polypeptide (VIP) and gastrin-releasing peptide (GRP) on hepatic microcirculation(More)
BACKGROUND The need for a fundoplication during repair of paraesophageal hiatal hernias (PEH) remains unclear. Prevention of gastroesophageal reflux represents a trade-off against the risk of fundoplication-related side effects. The aim of this trial was to compare laparoscopic mesh-augmented hiatoplasty with simple cardiophrenicopexy (LMAH-C) with(More)
BACKGROUND Because fundoplication-related side effects are frequent, we evaluated laparoscopic mesh-augemented hiatoplasty (LMAH) as a potential treatment option for gastroesophageal reflux disease and/or symptomatic hiatal herania. LMAH aims to prevent reflux solely by mesh-reinforced narrowing of the hiatus and lengthening of the intra-abdominal(More)
Minimally invasive surgery has gained significantly in importance over the last decade due to the numerous advantages on patient-side. The surgeon has to adapt special operation-techniques and deal with difficulties like the complex hand-eye coordination, limited field of view and restricted mobility. To alleviate these constraints we propose to enhance the(More)
The aim of the study was to determine if tumor seeding during laparoscopic surgery for cancer is a rare event or a typical complication of this procedure. Laparoscopic staging and treatment of intraabdominal tumors is increasing in gastroenterology, gynecology, and general surgery. A total of 1052 questionnaires were mailed to surgical department chairmen,(More)
BACKGROUND Robotic assistance or telemanipulation is the latest technological advance in minimally invasive surgery. Its future implementation will depend on the advantages that it can provide over standard laparoscopy or open surgery. METHODS All Medline-cited papers (from case reports to reviews) about telemanipulators used in visceral surgery were(More)
