RESUMEN
Self-expandable metallic stents (SEMS) are widely used for the palliative treatment of malignant strictures of the gastrointestinal tract. Recently, several studies tested whether a SEMS is an effective and safe option for benign esophageal stricture. Serious complications such as hemorrhage, compression of the bronchus, bronchoesophageal fistula, and esophageal rupture were infrequently encountered as complications of esophageal stent placement. Aortoesophageal fistula is extremely rare as a complication of esophageal SEMS insertion; only seven cases have been reported worldwide. We now report a case of an 80-year old female with aortoesophageal fistula after placement of a SEMS for an esophageal stricture.

Duplications of the gastrointestinal tract are rare congenital malformations that are usually present during the first decade of life. However, a smaller number of cases may remain occult until adulthood. Overall, the colon is the least common site of congenital gastrointestinal duplications. Colonic duplications can present with symptoms of diverticulitis and can be confused with acquired giant cysts or masses. We present a rare case of a duplication cyst of the colon in a female adult. Although the preoperative evaluations, including an abdominal CT scan and colonoscopy, were suggestive of a gastrointestinal tumor of the colon, the final diagnosis was a colonic duplication cyst based on the histopathologic examination of the resected specimen. Even if intestinal duplication cysts are uncommon, they should be considered in the differential diagnosis of intestinal masses.

Intussusception is a prolapse of a segment of the intestine into the lumen of the adjacent intestine. The majority of intussusceptions occur in infancy and early childhood. Intussusception arising in adulthood represents only about 5% of all intussusceptions and is usually caused by a malignant small bowel lesion acting as an apex for intussusception. Lipoma is not a common tumor in the gastrointestinal tract, and gastrointestinal lipomas may be submucosal or subserosal. Most of them are asymptomatic, although they may cause abdominal pain, bowel obstruction, and gastrointestinal bleeding. Intestinal intussusception caused by lipoma is uncommon and is particularly rare when the lipoma is located in the small intestine. We report an unusual case of intussusception in an adult male patient, which was caused by a lipomatous lesion located in the proximal jejunum acting as a lead point.

BACKGROUND/AIMS: Although endoscopic resection is widely used for the treatment of early colorectal cancer, the risk factors for lymph node metastasis are not clear. This study was designed to determine the risk factors for lymph node metastasis in patients with colorectal cancer who are treated by endoscopic resection. METHODS: The medical records of patients with histologically-proven early colorectal cancers who were treated by endoscopic resection between January 2002 and September 2008 were retrospectively reviewed. Information regarding the demographic data of patients and the clinicopathologic characteristics were recorded and analyzed. RESULTS: Twenty-nine patients who underwent subsequent surgical treatment after endoscopic resection for early colorectal cancer were enrolled in this study. Six patients (20.7%) had lymph node metastases on surgical pathologic examination. The predictive factors for lymph node metastasis were tumor morphology (non-polypoid flat tumors [p=0.019]), absence of background adenomas (p=0.033), and deep submucosal invasion > or = 2,000 um (p=0.012). Unexpectedly, the presence of vascular invasion was not associated with lymph node metastasis. CONCLUSIONS: The presence of vascular invasion might not be an absolute indication for additional surgical treatment of early colorectal cancer; however, deep submucosal invasion, accompanied by a gross tumor with a non-polypoid flat morphology, and the absence of background adenomas are potential risk factors for lymph node metastasis.

BACKGROUND/AIMS: The aim of this study was to compare the efficacy of lamivudine therapy between chronic hepatitis B (CHB) patients, whose ALT levels less than 2 times the upper limit of normal (ULN) and patients whose ALT levels are more than 2 times ULN. METHODS: We retrospectively analyzed 508 consecutive patients with HBeAg-positive CHB who were treated with lamivudine for 1 year or more. Forty-six patients (Group A) with pretreatment ALT levels less than 2 times ULN were retrospectively compared with 462 patients (Group B) whose ALT levels are more than 2 times ULN. RESULTS: HBeAg seroconversion was achieved in 15 (32.6%) of group A and 162 (35.1%) of group B. The cumulative rates of HBeAg seroconversion in group A and B were 19% and 21% at 12 months; 35% and 31% at 24 months; and 38% and 39% at 36 months, respectively. HBV breakthrough was observed in 20 (43.5%) of group A and 192 (41.6%) of group B. The cumulative breakthrough rates of group A and B were 18% and 12% at 12 months; 33% and 29 % at 18 months; 45% and 42% at 24 months, respectively. Post-treatment relapse in group A and B occurred in 56% (5/9) and 41% (44/108), respectively. Therefore, the rates of the HBeAg seroconversion, breakthrough, and post-treatment relapse were not significantly different between these two groups. CONCLUSIONS: Lamivudine therapy in HBeAg-positive CHB patients whose ALT levels are minimally elevated is as effective as in treatment of the patients whose pretreated ALT levels are twice more than ULN.

Pancreatic arteriovenous malformations (AVM) are extremely rare diseases frequently complicated by gastrointestinal hemorrhage. While surgical resection of affected lesion is preferred for the treatment of pancreatic AVM, angiographic intervention can be used as an alternative treatment, especially in surgically high-risk patients. We experienced a patient with pancreatic AVM manifested by hemobilia and biliary sepsis. Superior mesenteric and common hepatic arteriography showed pancreaticoduodenal AVM composed of nidus supplied by numerous fine feeding arteries and of draining veins encircling the common bile duct (CBD). Hemobilia was controlled by transportal coil embolization of draining veins of AVM around the CBD. Herein, we report this case with the review of literatures.

A Carcinoid tumor of the ampulla of Vater is extremely rare, accounting for less than 0.3% of all gastrointestinal carcinoids. Most reported cases have arisen from the gallbladder. An ampullary carcinoid most commonly presents with jaundice or upper abdominal discomfort, and bleeding from the tumor is exceedingly rare. A diagnosis is most frequently made postoperatively due to submucosal spread of the tumor. As the metastatic potential cannot be predicted by tumor size, a Whipple pancreaticoduodenectomy rather than local excision is considered the treatment of choice. We herein report a case of a primary carcinoid tumor located at the ampulla of Vater that presented as gastrointestinal bleeding; the tumor was diagnosed by an endoscopic biopsy after a papillary sphinterotomy.

Familial adenomatous polyposis (FAP) arises from germline mutations of the adenomatous polyposis coli (APC) gene. FAP is characterized by the occurrence of hundreds to thousands of adenomas throughout the colorectum, and there is nearly a 100% risk of colorectal cancer. In addition to polyposis coli, patients with FAP can develop a variety of extracolonic manifestations. Recent advances in screening and surgery have reduced the colon cancer occurrence and death in FAP patients, leaving desmoid tumors as a leading cause of their morbidity and mortality. Treatment of desmoid tumors is generally considered to be challenging for both the doctor and the patient. We report here on an 18 year old man with resectable intra-abdominal desmoid tumor that developed after total colectomy due to FAP and we include a review of the relevant literature.

It is difficult to perform endoscopic mucosal resection (EMR) in case of early gastric cancer involving duodenal bulb. To achieve complete resection, we applied a new METHOD: that is, EMR with an insulation-tipped diathermic knife (IT knife) was peformed by the retroflexion of endoscope in the bulb. This method was tried in 4 patients. For the antral side of the tumor, EMR was done using a needle knife or IT knife. The duodenal side of the tumor was resected by IT knife with the retroflexion of endoscope in the bulb. The complete resection was performed in 2 patients, an incomplete resection in one patient, and the laparoscopic subtotal gastrectomy was performed in the remaining one patient because reconstruction of partitional resection was very difficult and adenocarcinoma was found to involve the muscularis mucosa. We think that EMR with IT knife by endoscopic retroflexion in the bulb is effective for some cases of early gastric cancer involving the duodenal bulb.

BACKGROUND/AIMS: Reflux esophagitis is a recurring condition for which many patients require maintenance therapy. This comparative, randomized multicenter study was designed to evaluate the effect of long-term maintenance treatment comparing proton pump inhibitor, rabeprazole and H2 receptor antagonist, ranitidine. METHODS: Eighty four patients with healed reflux esophagitis confirmed by endoscopy were randomly allocated to receive maintenance treatment with either rabeprazole 10 mg once daily or ranitidine 300 mg once daily for 32 weeks. Patients were seen every 8 weeks or at symptomatic relapse. RESULTS: Of 84 initially treated patients, 73 entered the maintenance study. The percentage of asymptomatic patients after 90-day and 210-day treatment were 97% and 81.5%, for rabeprazole and 74.3% and 62.3%, for ranitidine, respectively. After 32 weeks, the relapse rates of esophagitis were 21.3% in the rabeprazole group and 62.9% in the ranitidine group (RR: 0.405, 95% CI: 0.215-0.766). CONCLUSIONS: Maintenance treatment with rabeprazole (10 mg once daily) is superior to ranitidine (300 mg once daily) in keeping the patients with reflux esophagitis in remission over a 32 week period.

Endoscopy has been the method of choice for the initial diagnosis and treatment of gastrointestinal bleeding. However, in the case of difficult localization or endoscopic failure, angiographic or surgical alternative may be recommended. The role of angiography has been emphasized recently to control upper GI bleeding. We experienced a case with deep ulcer displaying exposed vessel along the duodenal bulb, which imposed serious rebleeding risk. Although, active bleeding was controlled by the epinephrine injections in that patient, rebleeding risk was still high. So the patient underwent emergency angiography with embolization of the pancreaticoduodenal artery and gastroduodenal artery using multiple microcoils. Follow-up endoscopic examinations showed a coil protruding into the lumen from the ulcer bed, and the exposed coil at the ulcer base was completely by the regenerated epithelium three months later. Here in, we describe the rare case of a endodcopically exposed coil after embolization for bleeding duodenal ulcer which is the first case ever reported in Korea.

Broncho-esophageal fistula is a disease of varying etiologies. Spontaneous fistula occurs as a result of malignancy, radiotherapy or inflammatory disease. The majority of fistulas are caused by iatrogenic causes. Treatment of fistula usually consists of surgery and conservative management. Recently, it has been reported that broncho-esophageal fistula can be treated endoscopically using tissue adhesive agent such as Histoacryl(R) and fibrin glue. We report a case of broncho-esophageal fistula as a complication of tuberculosis that was successfully treated by radiological Histoacryl(R) injection therapy with a review of literatures.

BACKGROUND/AIMS: Lamivudine, an oral nucleoside analogue, effectively suppresses HBV replication and improves liver enzymes as well as liver histology. Long-term lamivudine therapy can induce the emergence of drug resistant HBV strains in some patients. The aim of this study was to evaluate the effects of lamivudine, the breakthrough rate, and the relapse rate of discontinuing therapy after HBeAg loss. METHODS: A total of 190 patients with HBeAg and HBV DNA positive showing abnormal serum levels of aminotransferases for at least 6 months received 100 mg of lamivudine once daily. The duration of lamivudine therapy was from 6-36 months (mean 14 months). Responder was defined as the ALT normalization with sustained suppression of HBV DNA and HBeAg loss. Therapy was to be stopped after HBeAg loss. Post-treatment monitoring continued for 1-21 months (mean 6 months). RESULTS: The cumulative HBeAg loss rates at 12 months and 18 months were 35% and 43%, respectively. Pretreatment serum HBeAg quantitation, and the duration of lamivudine therapy were independent predictive factors for HBeAg loss. The cumulative breakthrough rates at 18 and 24 months were 38% and 57%, respectively. Pretreatment HBV DNA level was the only predictable factor for breakthrough. Therapy was discontinued after HBeAg loss in 52 patients. Most episodes of relapse (15/16) occurred within 6 months after cessation of lamivudine. The cumulative relapse rates at 3 months and 6 months were 21% and 50%, respectively. A predictive factor for post-treatment relapse after HBeAg loss was the duration of lamivudine therapy. CONCLUSIONS: These results suggested the pretreatment quantitative HBeAg in serum and duration of lamivudine therapy are independent predictive factors for HBeAg loss. The HBeAg response of lamivudine-induced HBeAg loss was not durable after discontinuing therapy.

BACKGROUND: Although several epidemiologic studies have revealed that our dietary factors, obesity and alcohol are associated with an increased incidence of colon cancer, association of these factors with colorectal polyps is unclear. In this study, we tried to investigate the association between colorectal polyps and lifestyle factors in Korean adults. METHODS: Rectosigmoidoscopy was performed on all subjects from January 2001 to December 2001 at Ulsan University Hospital Health Promotion Center. Self-administered questionnaire for drinking and other life style factors was done. RESULTS: Among the 1,102 cases in which sigmoidoscopy examination was performed by a family physician, the prevalence of colorectal polyps was 17.6%. Smoking and drinking were significant risk factors for colon polyps. After adjusting for age and sex, using multiple logistic regression, the odds ratio of subjects with 20 pack years or more of smoking compared with the non-smoking subjects was 2.503 (95% CI: 1.277-3.299). Compared with non-drinking subjects, adjusted odds ratio in group with 3 or more times of drinking per week group was 2.833 (95% CI: 1.623-4.945). The odds ratio for the highest exercise group, compared with the lowest group was 0.539 (95% CI: 0.336-0.867). Exercise was associated inversely with colon polyps. Obesity was statistically insignificant in this study. CONCLUSION: These results showed that drinking and smoking were positively associated with colorectal polyps, but it was associated inversely with exercise.

BACKGROUND/AIMS: Impacted papillary stone (IPS) may lead to complete biliary obstruction and acute cholangitis. We evaluated clinical characteristics and endoscopic findings of IPS. METHODS: Data were obtained from patient recordings, radiologic and endoscopic reports in 14 patients. RESULTS: All patients had severe epigastric pain, but only 3 patients showed typical presentation of acute cholangitis. Radiologically, IPS was not found in 6 patients, but subsequently found as be a single IPS (n=5) and sandy stones filled in the bile duct and gallbladder (n=1). All patients showed a bulging and swollen papilla. Patients (n=9) without peripapillary diverticulum, or with extradiverticular papilla showed more posteriorly displaced papillary orifice and more frequent mucosal changes compared with patients (n=5) with intradiverticular papilla or juxtapapillary diverticulum. The stones were completely removed in 11 patients endoscopically, and the remainders, who had intradiverticular papilla, underwent surgical treatment. CONCLUSIONS: To predict IPS, clinical assessment is very important because the only characteristic manifestation is severe epigastric pain and radiological studies seem to be occasionally insufficient for detecting IPS. The characteristic endoscopic findings of IPS are bulging and swollen papillae with posterioriy displaced orifice and frequent mucosal changes, which may be influenced by presence or absence, and types of peripapillary diverticulum.

BACKGROUND: De novo methylation and transcriptional silencing of p16 gene is one of the main pathways in inactivation of p16 gene in colon neoplasm. But there has been no study about that in Korea yet. The aims of this study were to determine p16 methylation status and its association with clinicopathologic parameters and stage of colon cancers and adenomas in patients of Korea. METHODS: We examined p16 methylation of sixty primary colon cancer tissues and thirty colon adenoma tissues using methylation specific PCR after bisulfite modification of the DNA samples. RESULTS: In colon cancer group, 30 patients were male and the others were female, and the average age was 59.7+/-12.5 years. Three cases were in Dukes' stage A, 24 in B, 26 in C, and 7 in D respectively. p16 gene was methylated in 20% (12 of 60) of colon cancers. There was no significant correlation between methylation status of p16 gene and clinicopathologic variables of colon cancers including patient's age, sex, tumor location, size, and differentiation. In Dukes' stage C and D, methylation was positive in 24.2% (8/33 cases) comparing 14.8% (4/27 cases) in Dukes' A and B, but there was no significant difference statistically (p=0.52). In colon adenoma group, there were 15 simple adenomas, and 15 advanced adenomas (>or=1cm, including villous component, or high grade dysplasia). The p16 gene was methylated in 16.7% (5 of 30) of colon adenomas; in 3 cases of simple adenoma and in 2 cases of advanced adenoma. There was no significant correlation between p16 methylation status and clinicopathological variables in colon adenoma. CONCLUSION: The p16 gene was methylated in 20% of colon cancers and 16.7% of colon adenomas in the present series, suggesting that the methylation of p16 tumor suppressor gene might be expressed in similar rate in colon cancer/adenoma in Korea, and play a role in colorectal tumorigenesis in its early stage.

Santorinicele, a focal cystic dilatation of the distal duct of Santorini, has been suggested as a possible cause of the relative stenosis of the accessory papilla, is associated with complete pancreas divisum, which results in acute episodes of pancreatitis or pain. This report describes a case of a santorinicele, which was initially detected by upper gastrointestinal endoscopy as a polypoid mass, in a patient with recurrent abdominal pain. The mass was subsequently proved to be a santorinicele containing a pancreatic duct stone associated with incomplete pancreas divisum on endoscopic retrograde pancreatography. To the best of our knowledge this is believed to be the first description of a santorinicele associated with these characteristic findings.

BACKGROUND/AIMS: It has been reported that patients with chronic renal failure have a tendency foward increased incidences of peptic ulcer diseases. However, it is yet unclear whether the increased incidence is due to altered gastric acidity, hypersecretin of gastrin, or increased colonization of Helicobacter pylori (H. pylori). This study was conducted to investigate the role of H. pylori in the development of peptic ulcer diseases in patients with chronic renal failure. METHODS: Forty nine patients with end stage renal disease (ESRD) and 41 age-matched controls with normal renal function, were examined for H. pylori infection using a rapid urease test, histological examination with Hematoxylin, Eosin, Warthin-Starry silver stain, and culture. The presence of H. pylori was defined either as the positive culture or as positive for both CLO and histological examination. RESULTS: Ninteen (38.8%) out of 49 ESRD patients were positive for H. pylori, which was lower than 70.7% of the controls (p<0.01). Endoscopic examination revealed that 6 ESRD patients (12.2%) had peptic ulcers, while 2.4% of the controls did, which was not statistically significant. The ESRD patients were divided into two groups by therapeutic modality: group 1 included 31 patients under dialysis, and group 2, 18 patients with maintenance therapy. The incidence of H. pylori infection in group 1 was 51.6%, which was significantly higher than the 16.7% in group 2 (p<0.05). CONCLUSIONS: The results of this study suggest that the increased incidence of peptic ulcers in ESRD patients cannot be explained by H. pylori colonization, and that there may be other factors such as a high concentration of urea in the stomach of patients with ESRD, which can suppress the colonization of H. pylori.

It is known that the fluids bathing tumors might contain a higher level of the carcinoembryonic antigen (CEA) than those found in the blood. Therefore, we evaluated the role of bile CEA in diagnosing bile duct cancer. One hundred and thirty two patients were prospectively studied. The patients were divided into 3 groups: the bile duct cancer (n=32), pancreatic cancer (n=16), and benign biliary diseases (n=84) groups. Bile samples were obtained on the next day of the biliary drainage procedures. The mean bile CEA level in those with bile duct cancer (120.6+/-156.9 ng/mL) was significantly higher than those with pancreatic cancer and benign biliary diseases (32.0+/-28.5 ng/mL, 29.3+/-56.3 ng/mL). Using the level of 20 ng/mL, the sensitivity and specificity of bile CEA in the diagnosis of bile duct cancer from benign biliary diseases were 65.6% and 66.7%, respectively. Both the bile CEA and total bilirubin level were found to be an independent factor linked to bile duct cancer. This study result suggests that bile CEA level is a useful supplementary test for diagnosing bile duct cancer.

Amyloidosis results from the deposition of insoluble, fibrous amyloid proteins, nearly always in the extracellular spaces of organs and tissues. There are several varieties of amyloidosis, each of which is identified by the immunochemical nature of amyloid protein fibrils. Amyloid goiter is a very rare clinical entity and can be confused with a neoplasm. We have experienced a case of amyloid goiter with hypothyroidism secondary to tuberculosis. A 20 years old women with 5 months history of pulmonary tuberculosis was admitted with complaints of diarrhea, abdominal pain, weight loss at one year ago. She had a non-tender, diffuse and firm goiter. Also she had normal thyroid function at the first admission but was found to be hypothyroid at the second admission, 10 months later. Histologic examination revealed amyloid deposition in thyroid gland, stomach, colon and rectum.
