Background and study aims The safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) in very elderly patients remains unclear. The aim of this study was to evaluate the safety and efficacy of ESD for EGC in patients age 85 years and older. Patients and methods Patients who underwent ESD for EGC between September 2003 and April 2015 were divided into 3 group...

AIM For patients with superficial esophageal carcinoma, ESD was one of treatment modalities to remove the lesion safely and effectively. We perform this meta-analysis to determine the efficacy and incidence of complication of ESD for patients with superficial esophageal carcinoma. METHOD Articles were searched in MEDLINE (PubMed and Ovid), Cochrane Database of Systemic Reviews, Google scholar...

OBJECTIVE To summarize the technique and surgical outcome for total resection of lower sacral tumor. METHODS This retrospective study included 12 cases of total resection of lower sacral tumor (involving S3 and the below) from January 2010 to February 2013. Seven patients underwent en bloc resection and five cases accepted intralesional curettage. We used extraperitoneal approach to ligature ...

Due to the widespread acceptance of gastric and esophageal endoscopic submucosal dissections (ESDs), the number of medical facilities that perform colorectal ESDs has grown and the effectiveness of colorectal ESD has been increasingly reported in recent years. The clinical indications for colorectal ESD at the National Cancer Center Hospital, Tokyo, Japan include laterally spreading tumor (LST)...

Due to a lack of early symptoms, pancreatic cancers of the body and tail are discovered mostly at advanced stages. These locally advanced cancers often involve the celiac axis or the common hepatic artery and are therefore declared unresectable. The extended distal pancreatectomy with en bloc resection of the celiac artery may offer a chance of complete resection. We present the case of a 48-ye...

BACKGROUND/AIMS Endoscopic mucosal resection with circumferential mucosal incision (CMI-EMR) may offer benefits comparable to those of endoscopic submucosal dissection (ESD), while requiring less technical proficiency than ESD. METHODS We retrospectively compared the outcomes of CMI-EMR (n=34) and size-matched ESD (n=102), which were performed by a Korean endoscopist for colorectal epithelial...

Locally advanced right colon cancer may invade adjacent tissue and organs. Direct invasion of the duodenum and pancreas necessitates an en bloc resection. Previously, this challenging procedure was associated with high morbidity and mortality; however, today, this procedure can be done more safely in experienced centers. The aim of this study is to report our experience on en bloc right colecto...

Objective: To retrospectively assess the results of surgical treatment in a consecutive series of 110 patients with Stage IIb and IIIa non small cell lung cancer (NSCLC) invading chest wall. Methods: A series of 110 patients underwent surgery for Stage IIb and IIIa NSCLC with involvement of chest wall. There were 101 male and 9 female patients, mean age was 61.4 (range 32±74), 52 (47.3%) of the...

Gastric submucosal tumors (SMTs) less than 2 cm are generally considered benign neoplasms, and endoscopic observation is recommended, but SMTs over 2 cm, 40% of which are gastrointestinal stromal tumors (GISTs), have malignant potential. Although the Japanese Guidelines for GIST recommend partial surgical resection for GIST over 2 cm with malignant potential as well as en bloc large tissue samp...
