BACKGROUND: The purpose of this study was to evaluate the nationwide benefit and cost of the national cancer screening program (NCSP) for gastric cancer treatment. METHODS: For this nationwide, population-based study, the Korean National Health Insurance Big Data Base, which included gastric cancer-related treatment information and the costs for all patients with gastric cancer who were 40 years old or older between 2004 and 2013, was restructured. Patients with gastric cancer who participated i

For middle-third EGC, LAPPG can be considered as a better treatment option than LADG in terms of nutritional advantage and lower incidence of gallstone.

To evaluate the postoperative prognosis of AEJ within the stomach, AEJ II and AEJ III should be considered a part of gastric cancer irrespective of EGJ involvement.

DNA microarray analysis and validation by RT-PCR and TMA showed that overexpression of PAI-1 is related to aggressive LN metastasis in AGC.

PURPOSE: Intracorporeal anastomosis is the most difficult procedure during pure single-incision distal gastrectomy (SIDG) that affects its generalization. We introduced unaided delta-shaped anastomosis (uDelta), a novel anastomosis technique, for gastroduodenostomy after pure SIDG, and compared the results with those of previously reported Roux-en-Y anastomosis (RY). MATERIALS AND METHODS: Between March 2014 and March 2015, SIDG with D1+ lymph node dissection was performed for early gastric canc

OBJECTIVE: To evaluate the long-term outcomes of laparoscopic pylorus-preserving gastrectomy (LPPG) with laparoscopic distal gastrectomy (LDG) for early gastric cancer. BACKGROUND: Pylorus-preserving gastrectomy is considered a function-preserving surgery for early gastric cancer. However, there has been no multicenter randomized controlled trial comparing pylorus-preserving gastrectomy with distal gastrectomy until now. METHODS: A multicenter randomized controlled trial (KLASS-04) with 256 pati

The intraoperative estimated blood loss (EBL), an essential parameter for perioperative management, has been evaluated by manually weighing blood in gauze and suction bottles, a process both time-consuming and labor-intensive. As the novel EBL prediction platform, we developed an automated deep learning EBL prediction model, utilizing the patch-wise crumpled state (P-W CS) of gauze images with texture analysis. The proposed algorithm was developed using animal data obtained from a porcine experi

Based on rapid development of laparoscopic techniques and instruments, single-incision laparoscopic surgery (SILS) is expected to be the next step of "more" minimally invasive surgery. A few institutions gradually started to report their experience of single incision gastrectomy (SIG) for gastric cancer, but it is still difficult to accept that SIG can be performed as a popular procedure because of its technical difficulty. For wide adoption of SIG, the simplicity, safety and reproducibility of

BACKGROUND: Near-infrared (NIR) imaging with indocyanine green (ICG)-enhanced fluorescence is widely used in laparoscopic surgery. This study aimed to evaluate this technique's feasibility and usefulness in intraoperatively assessing vascular perfusion in a laparoscopically harvested omental flap. MATERIALS AND SURGICAL TECHNIQUES: From March 2015 to February 2016, we prospectively evaluated patients undergoing breast cancer surgery followed by immediate breast reconstruction using a laparoscopi
