OBJECTIVE The aim of this study was to evaluate the safety of this trial with respect to morbidity and mortality. SUMMARY BACKGROUND DATA Laparoscopic-assisted distal gastrectomy (LADG) is rapidly gaining popularity. However, there is limited evidence regarding its oncologic safety. We therefore conducted a phase III multicenter, prospective, randomized(More)
Duodenal gastrointestinal stromal tumors (GISTs) are uncommon and relatively small subset of GISTs whose optimal surgical procedure has not been well defined. We conducted this study to present the surgical experience in our institution and to analyze the postoperative outcome of duodenal GISTs. A retrospective clinicopathologic analysis was performed for(More)
OBJECTIVE To determine the safety of laparoscopy-assisted distal gastrectomy (LADG) compared with open distal gastrectomy (ODG) in patients with clinical stage I gastric cancer in Korea. BACKGROUND There is still a lack of large-scale, multicenter randomized trials regarding the safety of LADG. METHODS A large-scale, phase 3, multicenter, prospective(More)
OBJECTIVE The purpose of this study was to evaluate the impact of comorbidities on the surgical outcomes in laparoscopy-assisted distal gastrectomy (LADG). SUMMARY BACKGROUND DATA Although laparoscopic gastrectomy is less invasive than conventional open surgery, surgeons are still concerned with surgical outcomes associated with comorbidity. METHODS We(More)
BACKGROUND/AIMS This study aimed to compare the outcomes of endoscopic submucosal dissection (ESD) and gastrectomy based on the two sets of indications for ESD, namely guideline criteria (GC) and expanded criteria (EC). METHODS Between January 2004 and July 2007, 213 early gastric cancer (EGC) patients were enrolled in this study. Of these patients, 142(More)
The risk of recurrence and recurrence patterns after laparoscopy-assisted gastrectomy for gastric cancer remain unclear. The objective of this study is to assess recurrence and its timing, patterns, and risk factors following laparoscopy-assisted gastrectomy from multicenter data. A retrospective multicenter study was performed using data from 1,485(More)
PURPOSE The oncologic outcomes of laparoscopy-assisted gastrectomy for the treatment of gastric cancer have not been evaluated. The aim of this study is to validate the efficacy and safety of laparoscopic gastrectomy for gastric cancer in terms of long-term survival, morbidity, and mortality retrospectively. PATIENTS AND METHODS The study group comprised(More)
BACKGROUND Despite the initial absolute or relative contraindication of laparoscopic surgery during pregnancy, in the last decade, laparoscopic appendectomy (LA) has been performed in pregnant women. But few studies compare the outcomes of LA compared with open appendectomy (OA). We investigated clinical outcomes to evaluate the safety and efficacy of LA(More)
Since Kalloo and colleagues first reported the feasibility and safety of a peroral transgastric approach in the porcine model in 2004, various groups have reported more complex natural orifice transluminal endoscopic surgery (NOTES) procedures, such as the cholecystectomy, splenectomy and liver biopsy, in the porcine model. Natural orifice access to the(More)
A randomized controlled trial to evaluate the long-term outcomes of laparoscopic distal gastrectomy for gastric cancer is currently ongoing in Korea. Patients with cT1N0M0-cT2aN0M0 (American Joint Committee on Cancer, 6th edition) distal gastric cancer were randomized to receive either laparoscopic or open distal gastrectomy. For surgical quality control,(More)
