RESUMEN
PURPOSE: Obstructive jaundice in patients with hepatocellular carcinoma (HCC) is uncommon (0.5-13%). Unlike other causes of obstructive jaundice, the role of endoscopic intervention in obstructive jaundice complicated by HCC has not been clearly defined. The aim of this study was to evaluate the clinical characteristics of obstructive jaundice caused by HCC and predictive factors for successful endoscopic intervention. MATERIALS AND METHODS: From 1999 to 2009, 54 patients with HCC who underwent endoscopic intervention to relieve obstructive jaundice were included. We defined endoscopic intervention as a clinical success when the obstructive jaundice was relieved within 4 weeks. RESULTS: Clinical success was achieved in 23 patients (42.6%). Patients in the clinical success group showed better Child-Pugh liver function (C-P grade A or B/C; 17/6 vs. 8/20), lower total bilirubin levels (8.1+/-5.3 mg/dL vs. 23.1+/-10.4 mg/dL) prior to the treatment, and no history of alcohol consumption. The only factor predictive of clinical success by multivariate analysis was low total bilirubin level at the time of endoscopic intervention, regardless of history of alcohol consumption [odds ratio 1.223 (95% confidence interval, 1.071-1.396), p=0.003]. The cut-off value of pre-endoscopic treatment total bilirubin level was 12.8 mg/dL for predicting the clinical prognosis. Median survival after endoscopic intervention in the clinical success group was notably longer than that in the clinical failure group (5.6 months vs. 1.5 months, p< or =0.001). CONCLUSION: Before endoscopic intervention, liver function, especially total bilirubin level, should be checked to achieve the best clinical outcome. Endoscopic intervention can be helpful to relieve jaundice in well selected patients with HCC.

BACKGROUND/AIMS: Erlotinib and gemcitabine combined chemotherapy is becoming the treatment of choice in advanced pancreatic cancer. We evaluated the effectiveness of treatment with erlotinib plus gemcitabine and the prognostic factors for chemotherapeutic response in Korean pancreatic cancer patients. METHODS: Sixty-nine patients with advanced pancreatic cancer who were treated with daily erlotinib 100 mg orally and gemcitabine 1,000 mg/m2/30 min intravenous infusion on days 1, 8, and 15 of each 4-week cycle from 2006 to 2009 were included in this study. This study was a phase II single-center trial. RESULTS: All 69 patients with advanced pancreatic cancer were chemotherapy-naive. The objective response rate was 18.8%, and the overall tumor-stabilization rate was 49.2%. The median overall survival was 7.7 months (95% confidence interval [CI], 6.0 to 9.4 months). The median progression-free survival was 1.9 months (95% CI, 1.4 to 2.5 months). Prognostic factors for good chemotherapeutic response were good performance status and the presence of skin rash during chemotherapy. Patients with lower performance scores showed worse chemotherapeutic responses (odds ratio [OR], 7.6; 95% CI, 2.4 to 24.8). Poor responses were predicted by the absence of skin rash during chemotherapy (OR, 3.0; 95% CI, 1.4 to 6.3). CONCLUSIONS: Erlotinib and gemcitabine chemotherapy is a tolerable treatment regimen and has a favorable therapeutic effect in Korean patients with advanced pancreatic cancer.

BACKGROUND/AIMS: Biliary stenting is the most effective decompressive method for treating malignant biliary obstructive jaundice. Although the main cause of stent occlusion is tumor growth, few studies have investigated whether stent patency is affected by the combination of cancer-treatment modalities. The aim of this study was to evaluate the effects of local radiotherapy on metal-stent patency in patients with malignant biliary obstruction. METHODS: Patients who underwent self-expandable biliary metallic stenting for malignant biliary obstruction from 1999 to 2007 were included. Forty patients received chemotherapy and radiation therapy (radiation group, RG), and 31 patients received only chemotherapy (nonradiation group, NRG). RESULTS: The cumulative median stent patency was significantly longer in the RG than in the NRG (17.7 months; 95% confidence interval [CI], 1.8 to 33.6 months vs 8.7 months; 95% CI, 4.9 to 12.5 months; p=0.025). Stent occlusion caused by tumor growth or stent migration occurred in two (5%) and three (7.5%) cases in the RG and in six (19.3%) and two (6.5%) cases in the NRG, respectively. CONCLUSIONS: The patency of biliary metal stents in pancreatobiliary cancer patients who receive chemoradiation therapy is significantly longer than that in patients who do not receive radiotherapy, which suggests that local cancer control significantly affects stent patency.

BACKGROUND/AIMS: Studies have investigated the use of different types of radiofrequency capsules for comparison or sequential capsule endoscopy, but none have compared the MiroCam device - which utilizes a novel data transmission technology - with other capsules. This study compared the feasibility of sequential capsule endoscopy using the MiroCam and PillCam SB devices, which employ different transmission technologies. METHODS: Patients with diseases requiring capsule endoscopy were enrolled. After a 12-hour fast, one randomly selected capsule was swallowed. The second capsule was swallowed once fluoroscopy had indicated that the first capsule had migrated below the gastric outlet. RESULTS: The total operating time in 24 patients was 702+/-60 min (mean+/-SD) for the MiroCam and 446+/-28 min for the PillCam SB (p<0.0001). The rate of a complete examination to the cecum was 83.3% for the MiroCam and 58.3% for the PillCam SB (p=0.031). Diagnostic yields for the MiroCam, PillCam SB, and sequential capsule endoscopy were 45.8%, 41.7%, and 50.0%, respectively. The agreement rate between the two capsules was 87.5%, with a kappa value of 0.74. Electrical interference in data transmission between the two capsules was not observed, but temporary visual interferences were observed in seven patients (29.2%). CONCLUSIONS: Sequential capsule endoscopy with the MiroCam and PillCam SB produced slight but nonsignificant increases in the diagnostic yield, and the two capsules did not exhibit electrical interference. A larger trial is necessary for elucidating the usefulness of sequential capsule endoscopy.

A gastropericardial fistula, defined as penetration of a gastric lesion into the pericardium, is a rare occurrence. Such a fistula is usually associated with a huge ulcer in the gastric fundus, an ulcer within a hiatus hernia, a history of esophagogastric surgery, the concurrent use of non-steroidal anti-inflammatory drugs (NSAIDs), or Zollinger-Ellison syndrome. The patient in this case presented with shoulder pain and melena, caused by a gastropericardial fistula that had occurred as a late complication of postoperative esophagogastrostomy and a refractory gastric ulcer. Despite the severity of the condition, the patient showed great improvement after medical treatment and the fistula was cured at the end.

Malignant obstruction develops frequently in advanced gastric cancer. Although it is primarily the gastric outlet that is obstructed, there are occasional reports of colonic obstruction. Treating intestinal obstruction usually requires emergency surgery or stent insertion. There are several kinds of complications with stent insertion, such as bowel perforation, stent migration, bleeding, abdominal pain and reobstruction. Nevertheless, endoscopic stent insertion could be a better treatment than emergency surgery in cases of malignant bowel obstruction in cancer patients with poor performance status. We report a case of advanced gastric cancer with carcinomatosis in which a recurrent colonic stent was inserted at the same site because of cancer growth into the stent. The patient maintained a good condition for chemotherapy, thus improving their chances for survival.

BACKGROUND/AIMS: Well differentiated rectal carcinoid tumors which are less than 1cm in diameter can be treated by endoscopic resection. We aimed to evaluate the efficacy of endoscopic resection in treating small sized rectal carcinoids. METHODS: Medical records of 30 rectal carcinoid cases treated by endoscopic resection in Yonsei University College of Medicine, Severance Hospital between January 1995 and March 2007 were reviewed retrospectively. RESULTS: Mean age was 49.7 years and male to female ratio was 1:0.88. Mean size of tumor was 6.29+/-3.06 mm and 25 out of 30 patients (83.3%) had tumors of diameter less than 10 mm. Twenty-two out of 30 patients treated by conventional polypectomy, 6 by endoscopic mucosal resection using a transparent cap (EMR-C) and 2 by endoscopic submucosal dissection (ESD). Histological examination revealed that 9 patients had resection margin positive for tumor; 7 (31.8%) were in polypectomy group, 1 (16.7%) in EMR-C group, and 1 (50%) in ESD group (p=0.868). Five patients underwent transanal excision to remove residual tumor. No residual tumor was found in additionally resected tissue. Mean follow-up duration was 19. 3 months (range 0-122), and there were no recurrence. CONCLUSIONS: Endoscopic resection is an effective method in the treatment of small rectal carcinoids. However, long-term outcome remains to be elucidated by a large scaled prospective study.

Pulmonary choriocarcinoma is a very rare tumor in men. Herrein, the case of a pulmonary choriocarcinoma in 39-year-old man, and whether it had a primary nature, is reported. He denied any prior medical illness, but was admitted to our hospital with a history of a cough, and progressive dyspnea and hemoptysis 2 and 1 week duration, respectively. Chest radiographs on admission revealed a huge lung mass, 10 cm in diameter, in the left upper lung field, with left pleural effusion. Although biopsies using several diagnostic methods for the pathological confirmation were attempted, the pathology was not confirmed. Finally, the patient died after 2 months of regression. An autopsy of the lung was then performed.
