Résumé

BACKGROUND/AIMS: Outcomes of endoscopic submucosal dissection (ESD) for undifferentiated-type early gastric cancer (EGC) need to be further evaluated. We aimed to simulate the outcomes of ESD for undifferentiated-type EGC from a surgical database. METHODS: Among 802 patients who underwent gastrectomy with endoscopic biopsy for poorly differentiated adenocarcinoma (PD-type) or signet ring cell carcinoma (SRC-type), ESD candidates meeting the expanded indication (n=280) were selected by reviewing the endoscopic images. According to the surgical pathologic results, the outcomes of the ESD simulation were evaluated. RESULTS: Among the candidates, 104 (37.1%) were PD-type and 176 (62.9%) were SRC-type. The curative resection (CR) rate was 42.1%. Among the patients with CR, three patients (2.5%) showed lymph node metastasis (LNM). Three EGCs with CR and LNM were mucosal cancers ≥1.0 cm in size. The CR rate was higher in the SRC-type than in the PD-type (48.3% vs 31.7%, respectively, p=0.007). In the SRC-type, the CR rate was increased, with a smaller size criterion for the ESD indication, but was similar between the 1.0 cm and 0.6 cm criteria (63.3% and 63.6%, respectively), whereas the CR rate was below 50% in all of the different tumor size criteria (2.0 to 0.6 cm) in the PD-type. CONCLUSIONS: In undifferentiated-type EGC, ESD should be considered in selected patients with tumor sizes < 1 cm and SRC histology.

Résumé

Hepatocellular carcinomas (HCCs) in patients with Crohn's disease (CD) without underlying chronic hepatitis or liver cirrhosis are extremely rare. Previously reported cases occurred in patients who had developed CD at a young age and had been treated with immunosuppressive agents long-term. We herein report the first case of HCC in a 34-year-old patient with CD in Korea. The patient was treated with azathioprine for 14 years and had undergone repeated surgeries for CD. During the follow-up period, the patient was hospitalized for colon perforation and pericolic abscess formation. Computed tomography showed a liver mass, and HCC was diagnosed based on liver biopsy. The patient underwent right hemicolectomy for colon perforation and transcatheter arterial chemoembolization followed by radiofrequency ablation for the HCC. The present case is similar to previously reported cases with the exception of the liver pathology findings, which exhibited neither primary sclerosing cholangitis nor focal hepatic glycogenolysis.

Résumé

Endoscopic retrograde cholangiopancreatography is widely used for diagnosis and treatment of pancreatobiliary diseases and associated with a spectrum of complications such as pancreatitis, hemorrhage, and so on. Endoscopic papillary balloon dilatation (EPBD) has an advantage over endoscopic sphincterotomy in complication of bleeding. We report here on a 68-year-old woman who developed metabolic encephalopathy due to massive bleeding after EPBD. Massive bleeding was controlled after selective embolization and metabolic encephalopathy was improved after conservative management. Metabolic encephalopathy due to massive bleeding after EPBD has not been reported. We report on this unusual case along with a review of the related literatures.

Résumé

BACKGROUND/AIMS: Few studies have investigated the prognosis of non-gastric gastrointestinal stromal tumors (GISTs) under the modified National Institutes of Health (NIH) consensus criteria in Korea. This study aims to clarify the clinical usefulness of the modified NIH criteria for risk stratification. METHODS: From January 2000 through October 2012, 88 patients who underwent curative resection for primary GISTs were included in this study. The enrolled patients were stratified to predict recurrence by the original NIH criteria and modified NIH criteria. RESULTS: In all, 88 patients had non-gastric GISTs, including 82 and 6 patients with GISTs of the small intestine and colorectum, respectively. The mean age was 57.3+/-13.0 years, and the median follow-up duration was 3.40 years (range, 0.02-12.76 years). All patients who were placed in the intermediate-risk category according to the original NIH criteria were reclassified into the high-risk category according to the modified NIH criteria. Therefore, the proportion of cases in the intermediate-risk category declined to 0.0% from 25.0% (22/88), and the proportion of cases in the high-risk category increased to 43.2% (38/88) from 18.2% (16/88) under the modified NIH criteria. Among the 22 reclassified patients, 6 (27.3%) suffered a recurrence during the observational period, and the recurrence rate of high-risk category patients was 36.8% (14/38). CONCLUSIONS: Patients in the high-risk category according to the modified NIH criteria had a high GIST recurrence rate. Therefore, the modified NIH criteria are clinically useful in selecting patients who need imatinib adjuvant chemotherapy after curative surgical resection.

Résumé

Epidermoid cyst in the intrapancreatic accessory spleen is extremely rare condition which could be mistaken for pancreatic cystic neoplasm. We report two cases of epidermoid cysts of intrapancreatic accessory spleen which mimicking pancreatic cystic neoplasm. Two patients, both male, aged 47 and 53 respectively were referred to our department for pancreatic mass. One was asymptomatic, whereas the other presented worsening abdominal pain and progressive weight loss. In both cases, the mass with cystic component was detected in the pancreatic tail in a computed tomography scan. Under a suspicion of pancreatic cystic neuronendocrine tumor, they underwent a distal pancreatectomy. Pathologic feature of resected specimens were shown to benign squamous lined cyst with splenic tissue in and around cyst wall which suggested that epidermoid cysts in the accessory spleen. We should take into account the possibility of epidermoid cyst in the intrapancreatic accessory spleen in the differential diagnosis of pancreatic cystic lesion.
