BACKGROUND Although the issue of drain use in open cholecystectomy has been adequately addressed by prospective randomized trials, there is lack of evidence on the usefulness of drains in elective laparoscopic cholecystectomy, and the surgeons follow their beliefs and bias on this debate. Therefore, a controlled randomized trial was designed to assess the(More)
OBJECTIVE To compare spinal anesthesia with the gold standard general anesthesia for elective laparoscopic cholecystectomy in healthy patients. DESIGN Controlled randomized trial. SETTING University hospital. PATIENTS One hundred patients with symptomatic gallstone disease and American Society of Anesthesiologists status I or II were randomized to(More)
BACKGROUND Regional anesthesia has not been used as the sole anesthetic procedure other than in the scenario of a patient at high risk to undergo laparoscopic cholecystectomy with CO2 pneumoperitoneum under general anesthesia. METHODS Fifteen ASA grade I or II patients underwent laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under(More)
Groin sepsis requiring mesh removal is said to be a rare complication of tension-free inguinal hernioplasty. Furthermore, late-onset deep-seated prosthetic infection seems to be an unexpected complication. The aim of this study was to report our experience on late mesh infection occurring years after open hernia repair. Between 1998 and 2005, 1,452 patients(More)
BACKGROUND Although the ideal management of cholecysto-choledocholi-thiasis is controversial, the 2-stage approach [endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, and common bile duct (CBD) clearance followed by laparoscopic cholecystectomy] remains the standard way of management worldwide. One-stage approach using the so-called(More)
BACKGROUND Regional anesthesia has not been used as the sole anesthetic procedure in laparoscopic ventral hernia repair due to the fear of potential adverse effects of the pneumoperitoneum. However, there are recent reports on the feasibility of performing laparoscopic procedures, such as cholecystectomy, in fit patients, under spinal anesthesia alone. The(More)
BACKGROUND The laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair is an evolving technique associated with the well-known advantages of a minimally invasive approach. However, general anesthesia is routinely required for the procedure. Based on our previous experience in regional anesthesia for laparoscopic procedures, we designed a(More)
Impaired neorectal function or sphincter incompetence have been respectively implicated as causative factors of increased frequency of defaecation or incontinence after low anterior resection of the rectum (LARR) for rectal carcinoma, although individual mechanisms of anorectal function have not been fully studied. Functional and laboratory results were(More)
AIM To study the timing of laparoscopic cholecystectomy for patients with acute cholecystitis. METHODS Between January 2002 and December 2005, all American Society of Anesthesiologists classification (ASA) I, II and III patients with acute cholecystitis were treated laparoscopically during the urgent (index) admission. The patients were divided into three(More)
BACKGROUND Therapeutic ERCP has an established role in the treatment of pancreatobiliary diseases, but little information is available on the outcomes of this procedure in patients 90 years of age and older. OBJECTIVE To evaluate the efficacy and the safety of therapeutic ERCP in an extremely elderly cohort. DESIGN Retrospective study. SETTING Two(More)
