Gastric dysplasia is a neoplastic lesion and a precursor of gastric cancer. The Padova, Vienna, and World Health Organization classifications were developed to overcome the discrepancies between Western and Japanese pathologic diagnoses and to provide a universally accepted classification of gastric epithelial neoplasia. At present, the natural history of gastric dysplasia is unclear. Much evidence suggests that patients with high-grade dysplasia are at high risk of progression to carcinoma or synchronous carcinoma...

BACKGROUND AND AIMS: Endoscopic resection for mucosal gastric cancer (MGC) is highly recommended in the absence of lymph node metastasis (LNM). We aimed to clarify the risk factors for LNM in MGC and to investigate the association of LNM with the indication criteria for endoscopic submucosal dissection (ESD). METHODS: A retrospective cohort study was performed on 3951 patients with MGC who underwent radical gastrectomy at the Samsung Medical Center in Seoul, Republic of Korea, between September 1994 and September 2010...

BACKGROUND: Although endoscopic submucosal dissection (ESD) is a widely accepted treatment for early gastric cancer (EGC), there is no consensus regarding the management of positive horizontal margin (HM) despite en bloc ESD. The aim of the current study was to identify the risk factors and optimal management of positive HM in EGCs resected by en bloc ESD. METHODS: A total of 890 consecutive patients with 1,053 intramucosal EGCs resected by en bloc ESD between April 2005 and June 2011...

BACKGROUND: Widespread application of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) results in noncurative resection in some patients. The influence of preceding ESD on additional gastric resections has not been completely evaluated. METHODS: Endoscopic, surgical, and pathological records of 255 patients who underwent additional gastrectomy after noncurative ESD at a single prefectural cancer center from September 2002 to December 2010 were reviewed...

BACKGROUND: The aim of this study was to compare the postoperative health-related quality of life (HRQOL) between open and laparoscopic distal gastrectomy. METHODS: A multi-institutional nonrandomized study was conducted. Patients with clinical T1 gastric cancer were prospectively enrolled and underwent distal gastrectomy by either the open or laparoscopic approach. HRQOL was measured using the European Organization for Research and Treatment of Cancer, Quality of Life Questionnaire-Core 30 and the site-specific module for gastric cancer...

BACKGROUND: Although proximal gastrectomy (PG) is widely accepted as a function-preserving operation for early upper-third gastric cancer, postoperative disorders, such as reflux or gastric stasis, have often been pointed out. From the perspective of postoperative disorder, the choice of total gastrectomy (TG) or PG for such cancers is still controversial. By using the newly developed Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, the quality of life after TG and PG was compared...

We systematically searched Medline and Cochrane Library and the related references occurred in the citations until February 2013 and included all the cases who suffered from gastric benign and malignant diseases where single incision laparoscopic surgery was performed. A total of 69 cases with gastric diseases undergoing SILS surgery were reviewed to evaluate the feasibility, safety, and potential benefits of SILS for the gastric diseases. Demographic data, morphologic characterisation of the lesion, and perioperative parameters were analyzed retrospectively...

The theory behind using sentinel node mapping and biopsy in gastric cancer surgery, the so-called sentinel node navigation surgery, is to limit the extent of surgical tissue dissection around the affected organ and subsequently the accompanied morbidity. However, obstacles on the clinical correspondence of sentinel node navigation surgery in everyday practice have occasionally alleviated researchers' interest on the topic. Only recently with the widespread use of minimally invasive surgical techniques, i.e...

AIM: To compare the short-term outcomes of patients who underwent proximal gastrectomy with jejunal interposition (PGJI) with those undergoing total gastrectomy with Roux-en-Y anastomosis (TGRY). METHODS: From January 2009 to January 2011, thirty-five patients underwent PGJI, and forty-one patients underwent TGRY. The surgical efficacy and short-term follow-up outcomes were compared between the two groups. RESULTS: There were no differences in the demographic and clinicopathological characteristics...
