ABSTRACT
BACKGROUND/AIMS: Endoscopic pancreatic ductal drainage may help alleviate the pain from chronic pancreatitis, but stricture dilatation may be technically difficult. Dilatation of high grade strictures of the pancreatic ducts with using dilating or balloon catheters may result in failure. We evaluated the efficacy of using the Soehendra stent retriever as a dilator. METHODS: Fourteen patients with pancreatic stricture had dilation performed with a Soehendra stent retriever. Each patient had sphincterotomy, guidewire placement and stent retriever dilatation. RESULTS: All procedures were successful and none of the patients had complications. Symptom relief was observed after dilation in all patients. There was no complication associated with the use of the stent retriever. None of the patients have relapsed for 6 months. CONCLUSIONS: The Soehendra stent retriever is safe and effective as a dilating device for the pancreatic strictures that are resistant to conventional dilation.

BACKGROUND/AIMS: The extraction of large common bile duct (CBD) stones after an endoscopic sphincterotomy (EST) is successful in 80~90% of cases but it often requires a prolonged time and repeated trials. This study investigated the utility of a combined endoscopic papillary large balloon dilatation (EPLBD) and a mid-incision of an EST (m-EST) method for the removal of large CBD stones. METHODS: Thirty patients with large CBD stones were enrolled in this study. EPLBD was carried out using the one-step inflation of a 15~18 mm diameter balloon after m-EST. RESULTS: The maximum stone diameter was 21.62+/-5.38 mm. Twelve patients had more than 4 stones, 7 patients had 2 stones, and the remainder had a single large stone. Complete ductal clearance was achieved in all patients. After the procedure, the serum amylase and/or lipase levels were elevated in 3 patients (13.3%). However, there was no episode of true pancreatitis. Minor bleeding was encountered in only one patient (3.3%), and was easily controlled by an endoscopic epinephrine injection. The procedure was carried out safely in 6 patients with periampullary diverticulum. No perforation or mortality was encountered. CONCLUSIONS: Combined EPLBD and m-EST is a safe and effective method, and may be a good alternative treatment for removing large CBD stones.

Collagen and its products, used in some medical field are relatively safe but may induce hypersensitivity reaction. However, pulmonary embolism is a rare but serious complication after injection of them. A-48-year old woman was admitted because of cough, hemoptysis and dyspnea. Nine days ago, she had received breast augmentation with injectable collagen by unlicensed person. Four days later, she experienced cough, hemoptysis and dyspnea. On admission right side pleural effusion and peripheral distributed diffuse consolidations in both lungs were noted on chest radiograph. A computed tomographic (CT) scan of the chest showed non-segmental distribution of bilateral ground-glass opacity and interlobular septal thickening with multifocal consolidation in both lungs. Sputum and urine cytologic examination revealed foamy histiocytes containing lipid vaculoes. Conservative management was done under the impression of pulmonary embolism after collagen injection. She was dischared with full recovery. Here, we report a case of pulmonary embolism occurred after infection of collagen first in Korea.

BACKGROUND/AIMS: The clinical usefulness of urinary trypsinogen-2 dipstick test is still in controversy. We evaluated the usefulness of urinary trypsinogen-2 dipstick test in patients with acute pancreatitis. METHODS: Urinary trypsinogen-2 dipstick test was prospectively performed in 50 patients with acute pancreatitis, 50 patients with non-pancreatic abdominal pain, and 50 healthy controls. RESULTS: On admission, urinary trypsinogen-2 dipstick test was positive in 36 of 50 patients with acute pancreatitis (sensitivity, 72%) and in 4 of 50 patients with non-pancreatic abdominal pain (specificity, 92%). On the other hand, it was all negative in controls. The sensitivity and specificity of serum lipase were 78% and 94%, respectively. At 24 hours after admission, the positive rate of urinary trypsinogen-2 dipstick test rose from 72% to 94% (p=0.02). The results of urinary trypsinogen-2 dipstick test was positive in 14 of 15 patients with severe pancreatitis and 22 of 35 patients with mild pancreatitis according to the criteria by Atlanta International Symposium, 1992. CONCLUSIONS: Urinary trypsinogen-2 dipstick test is comparable to serum lipase in diagnosing acute pancreatitis. Delayed measurement and severe pancreatitis are more likely to yield positive results with urinary trypsinogen-2 dipstick test. Thus, we suggest that the cut-off value of urinary trypsinogen-2 dipstick test should be lowered to increase its sensitivity.

Self-expandable metallic stent (SEMS) has been reported to provide effective treatment alternatives with minimal morbidity for patients with malignant gastroduodenal obstruction. Limitations of SEMSs are stent occlusion due to tumor ingrowth or overgrowth and stent migration. Migrated stents may remain in the stomach or travel distally. To our knowledge, however, migration of pyloric SEMS to the esophagus has not been reported. We experienced such a case in a 65-year-old woman who had undergone a gastrojejunostomy and choledochojejunostomy due to unresectable pancreatic head cancer. Pyloric SEMSs (Niti-S Pyloric Bare Stent, 18x60 mm, Taewoong Medical, Korea) were deployed at the obstructed efferent and afferent loops. After severe vomiting, a pyloric SEMS placed at the afferent loop migrated into the esophagus, which caused severe chest pain and intractable hiccup. It was removed endoscopically. This case illustrates that pyloric SEMS can migrate to the esophagus through the lower esophageal sphincter.

Epiphrenic diverticulum is a relatively rare condition resulting from mucosal herniation through the muscular wall of the esophagus. This pulsion diverticulum is often associated with abnormal esophageal motility such as esophageal achalasia. Although pneumatic dilatation is recommended as the initial treatment for patients with esophageal achalasia, some authors caution against the use of pneumatic dilatation when esophageal achalasia is complicated by epiphrenic diverticulum. A 49-year old female patient was admitted due to progressive dysphagia for both solid and liquid foods, and weight loss and frequent vomiting. She suffered from Heller's myotomy due to esophageal achalasia 8 years prior. She was diagnosed as having recurrent esophageal achalasia with epiphrenic diverticulum due to incomplete myotomy, using esophagography, esophagogastrodudenoscopy, esophageal manometry, and esopahgeal transit scan. The patient was successfully treated with pneumatic balloon dilatation, and her symptoms markedly improved.
