Although surgery was the standard treatment for early gastrointestinal cancers, endoscopic resection is now a standard treatment for early gastrointestinal cancers without regional lymph node metastasis. High-definition white light endoscopy, chromoendoscopy, and image-enhanced endoscopy such as narrow band imaging are performed to assess the edge and depth of early gastrointestinal cancers for delineation of resection boundaries and prediction of the possibility of lymph node metastasis before the decision of endoscopic resection. Endoscopic mucosal resection and/or endoscopic submucosal dissection can be performed to remove early gastrointestinal cancers completely by en bloc fashion. Histopathological evaluation should be carefully made to investigate the presence of risk factors for lymph node metastasis such as depth of cancer invasion and lymphovascular invasion. Additional treatment such as radical surgery with regional lymphadenectomy should be considered if the endoscopically resected specimen shows risk factors for lymph node metastasis. This is the first Korean clinical practice guideline for endoscopic resection of early gastrointestinal cancer. This guideline was developed by using mainly de novo methods and encompasses endoscopic management of superficial esophageal squamous cell carcinoma, early gastric cancer, and early colorectal cancer. This guideline will be revised as new data on early gastrointestinal cancer are collected.

BACKGROUND/AIMS: Many authors recommend performing a second-look endoscopy (SLE) to reduce the frequency of delayed bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasms, but these recommendations have been made despite a lack of reliable evidence supporting the effectiveness of SLE. METHODS: From January 2012 to May 2013, we investigated 441 gastric neoplasms treated by ESD to assess the risk factors for delayed bleeding. Delayed bleeding occurred in four of these lesions within 1 postoperation day. Therefore, we enrolled the patients with the remaining 437 lesions to determine the utility of SLE performed on the morning of postoperative day 2. All lesions were randomly assigned to SLE (220 lesions) groups or non-SLE (217 lesions) groups. RESULTS: Delayed bleeding occurred in 18 lesions (4.1%). A large tumor size (>20 mm) was the only independent risk factor for delayed bleeding (p=0.007). The chance of delayed bleeding was not significantly different between the patients receiving a SLE (eight cases) and those patients not receiving a SLE (six cases, p=0.787). Furthermore, SLE for lesions with a large tumor size did not significantly decrease delayed bleeding (p=0.670). CONCLUSIONS: SLE had little or no influence on the prevention of delayed bleeding, irrespective of the risk factors.

BACKGROUND: The expression of c-FLIP (cellular Fas-associated death domain-like interleukin-1 beta-converting enzyme (FLICE)-inhibitory protein), which is a member of the family of inhibitors of apoptosis, has been associated with tumor development and progression. The aim of this study was to evaluate the expression of c-FLIP in gastric cancer and its correlation with tumor cell proliferation, apoptosis and the clinicopathologic features. METHDOS: Immunohistochemical staining with anti-c-FLIP antibody was performed in 98 tissue samples obtained from gastric cancer patients who underwent surgical treatment. The apoptotic cells were visualized by terminal deoxynucleotidyl transferase (TdT) mediated deoxyuridine triphosphate (dUTP) nick-end labeling (TUNEL), and the proliferative cells were visualized by staining with Ki-67 antibody. RESULTS: The positive expression of c-FLIP in the gastric cancer tissues was demonstrated in 57.1% of the cases. The expression of c-FLIP was increased in the gastric cancer tissues compared with the matched normal gastric mucosa. The expression of c-FLIP was significantly associated with histologic differentiation (p=0.038). However, there was no association between the c-FLIP expression and the other clinicopathological parameters, including patient survival. The Ki-67 labeling index (KI) for the 98 tumors ranged from 7.6 to 85.0 with a mean KI of 50.4+/-15.7. The mean KI value of the c-FLIP positive tumors was 54.1+/-15.3 and this was significantly higher than that of the c-FLIP negative tumors (p=0.005). The apoptotic index (AI) for the 98 tumors ranged from 0.0 to 10.0 with a mean AI of 7.4+/-2.3. There was no significant difference between the c-FLIP expression and the AI (p=0.347). CONCLUSIONS: These results suggest that the c-FLIP expression may be associated with tumor cell proliferation of gastric cancer.

PURPOSE: To report a patient with Freeman-Sheldon syndrome with blepharophimosis. METHODS: A 4-year-old girl with congenital facial abnormalities consistent with Freeman-Sheldon syndrome presented with complaints of blepharophimosis. The characteristic features of microstomia, down-slanting palpebral fissure, blepharoptosis, and telecanthus were also found. Y-V epicanthoplasty and levator aponeurosis resection were performed. RESULTS: Surgical intervention to correct ptosis and telecanthus led to initially fair cosmetic results, but one month later an unexpected decrease in interpalpebral fissure height was noted. CONCLUSIONS: Freeman-Sheldon syndrome with blepharophimosis is very rare. It was necessary to correct blepharoptosis, telecanthus, and blepharophimosis in the oculoplastic service in this case.
