Laparoscopy-assisted gastrectomy (LAG) is a complex and time-consuming procedure, which is increasingly used for early gastric cancer (EGC). We provide a multidimensional analysis of the learning curve in LAG. Cumulative sum method was used to analyze outcomes of 109 patients undergoing LAG for EGC by one surgeon over a two year period; the influence of(More)
PURPOSE This study aimed to verify the long-term outcome of a minimally invasive endoscopic or laparoscopic approach for the treatment of gastric gastrointestinal stromal tumor (GIST). METHODS This single-center study involved a retrospective review of gastric tumors that were pathologically confirmed as GIST. A total of 84 patients who underwent(More)
PURPOSE With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. METHODS From March 2005 to May 2010, clinical(More)
BACKGROUND/AIMS Xanthogranulomatous cholecystitis (XGC) is a rare disease of the gallbladder, showing high conversion rate and complications. However, it has been reported as collected data or as a case review. Therefore, we compared surgical outcomes of laparoscopic cholecystectomy (LC) in patients who were diagnosed with XGC with that of other(More)
PURPOSE Clinical stage of gastric cancer is currently assessed by computed tomography. Accurate clinical staging is important for the tailoring of therapy. This study evaluated the accuracy of clinical N staging using stomach protocol computed tomography. MATERIALS AND METHODS Between March 2004 and November 2012, 171 patients with gastric cancer(More)
The aim of this study was to evaluate the surgical outcomes of laparoscopic cholecystectomy (LC) in patients who were diagnosed with severe acute cholecystitis (SAC) and to clarify the useful treatment modalities of SAC. Of 112 patients who presented SAC, we selected 99 patients and divided them into 3 groups: 37 patients who underwent preoperative(More)
BACKGROUND/AIMS The aim of this study was to analyze the clinical/pathological outcomes of patients that underwent surgery for gallbladder adenomyomatosis, to clarify the characteristics of the type and pathogenesis of adenomyomatosis. METHODOLOGY From May 1997 to March 2008, 4704 consecutive patients underwent cholecystectomy at Ajou University Medical(More)
AIM To introduce robotic cholecystectomy (RC) using new port sites on the low abdominal area. METHODS From June 2010 to June 2011, a total of 178 RCs were performed at Ajou University Medical Center. We prospectively collected the set-up time (working time and docking time) and console time in all robotic procedures. RESULTS Eighty-three patients were(More)
We present a 69-year-old woman with a duodenal obstruction after successful selective transcatheter arterial embolization (TAE) for a duodenal diverticular hemorrhage. Two weeks after TAE, the patient showed abrupt symptoms of duodenal obstruction. Resolving hematomas after successful selective transcatheter arterial embolization should be thoroughly(More)
Gastric lipomatosis is an extremely rare condition. We present a case of a 69-year-old woman admitted with epigastric soreness. Computerized tomography (CT) revealed extrinsically compressing, fat-containing mass lesions on the entire gastric wall of the antrum and body except for the lesser curvature. A subtotal gastrectomy was performed. Pathology(More)
