BACKGROUND The goal of this study was to evaluate the effect of peritrocal, intraperitoneal, or combined peritrocal-intraperitoneal ropivacaine on the parietal, visceral, and shoulder tip pain after laparoscopic cholecystectomy. METHODS Eighty patients were randomly assigned to four groups. Group A received peritrocal and intraperitoneal saline. Group B(More)
To compare the economic outcomes of laparoscopic surgery (LAP) with those of open surgery (OS) for colorectal cancer. We compared operating room (OR) costs, OR hospital-profits, total hospital charges, and payments made for 67 consecutive patients who underwent either OS (n = 41) or LAP (n = 26) for colorectal cancer. The operating time was longer in the(More)
BACKGROUND The preemptive intravenous injection of local anesthetics is known to improve postoperative pains in abdominal surgery. The aim of this study is to assess the effect of intravenous lidocaine injection and analyze the precise amount of pain by computerized patient-controlled analgesia (PCA) in patients who had undergone laparoscopy-assisted distal(More)
Despite the increasing number of recent reports on laparoscopic liver resection in adults, there are only rare reports on such a procedure being performed in children. The authors report here on a total laparoscopic left lateral sectionectomy that was performed in a 5-year-old girl who had a cystic tumor of the liver. The operative time was 150 minutes, the(More)
INTRODUCTION Dermoid cyst of the pancreas, also called cystic teratoma, is a benign, well-differentiated, and extremely rare germ cell neoplasm. Preoperative diagnosis is challenging since there are no definitive preoperative diagnostic tests or pathognomonic findings. PRESENTATION OF CASE We report a case of a 54-year-old male who presented with an(More)
OBJECTIVES This randomized, double-blind, placebo-controlled trial evaluated intraperitoneal (IP) lidocaine administration and intravenous (IV) lidocaine infusion for postoperative pain control after laparoscopic cholecystectomy (LC). METHODS Patients who underwent LC were randomized to either group IV (intravenous lidocaine infusion), group IP(More)
OBJECTIVE To describe the computed tomographic findings of appendiceal diverticulitis. METHODS Computed tomography (n = 20) and clinical findings in 23 patients with appendiceal diverticulitis were retrospectively reviewed and compared with those in 23 patients with usual acute appendicitis. RESULTS Computed tomography visualized the inflamed(More)
BACKGROUND Intra-abdominal application of anti-adhesive barriers may reduce the extent and severity of postoperative adhesions. This study was designed to compare the effectiveness of a sprayable liquid barrier (a mixed solution of sodium hyaluronate and carboxymethylcellulose) with two conventional sheets. METHODS Eighty male Sprague Dawley rats(More)
PURPOSE To further improve the advantages of minimally invasive surgery, single port laparoscopic techniques continue to be developed. We report our initial experience with single port laparoscopic appendectomy (SPLA) in children and compare its outcomes to those of conventional laparoscopic appendectomy (CLA). METHODS Clinical data were prospectively(More)
BACKGROUND Cystic duct adenocarcinoma is a rare disease because the cystic duct has a short length and a narrow cavity. Cystic duct adenocarcinoma accounts for 8% of all gallbladder adenocarcinoma; of these, adenocarcinoma that develops from the remnant cystic duct after cholecystectomy is extremely rare. We report a case of incidentally detected(More)
