Bezoars are conglomerates of nondigestible matter in the gastrointestinal tract that may or may not be accompanied by gastrointestinal manifestations. Bezoars develop in patients with previous gastric surgery or in those patients with delayed gastric emptying that is due to gastroparesis caused by hypothyroidism or diabetes mellitus. Small bowel obstruction due to a gastric bezoar is rare, but it can lead to severe complications such as intestinal perforation, compression necrosis etc. A female patient came to our department complaining of upper abdominal pain and she was diagnosed as having a bezoar that was causing afferent loop syndrome and pancreatitis. We attempted to manage the patient by inserting a nasogastric tube, performing gastrofibroscopy and implementing percutaneous transhepatic biliary drainage, but the patient's condition worsened and deteriorated into a septic condition. An operation was planned, but the patient showed improvement owing to the migration of the bezoar. Herein, we report on a case of afferent loop syndrome due to bezoar and this was complicated by acute pancreatitis.

Congenital insensitivity to pain with anhidrosis (CIPA) is a rare, autosomal-recessive disorder characterized by the clinical triad of indifference of pain, anhidrosis and heat intolerance.Because of their lack of autonomic response to noxious stimuli, the determination of adequate depth of anesthesia in the CIPA patient undergoing surgery is a major challenge.We experienced a patient with CIPA who had minor procedures three times under the general anesthesia, in which bispectral index (BIS) was maintained at 40-50 by adjusting sevoflurane concentrations with 50% nitrous oxide.The low end-tidal sevoflurane concentrations (<1.2 vol%) were required to keep the target BIS while vital signs remained stable throughout the surgery in each operation.BIS monitor may be a valuable tool to guide the depth of anesthesia in patients with CIPA.

Phlegmonous gastritis is a rare disorder caused by suppurative bacterial infection of the gastric wall. The mortality rate remains extremely high and the gastrectomy has been thought to be an effective form of treatment. We report a case of acute phlegmonous gastritis developed in a patient with advanced alcoholic liver cirrhosis, and recovered with early endoscopic diagnosis and antibiotics alone.

BACKGROUND/AIMS: Several studies suggested that serum cystatin C (CysC) is more useful than serum creatinine (Cr) for the assessment of renal function in patients with liver cirrhosis. This study evaluated the clinical significance of CysC in patients with cirrhotic ascites and normal Cr level. METHODS: We enrolled patients with cirrhotic ascites and a normal serum Cr level (<1.2 mg/dL). GFR was measured by 99mTc-DTPA renal scan. Serum Cr, CysC, and Cr clearance (CCr) were measured on the same day. Significant renal impairment and severe renal impairment were defined as GFR <60 mL/min and GFR <30 mL/min, respectively. RESULTS: Eighty-nine patients with cirrhotic ascites were enrolled in the study (63 men and 26 women; age, 55+/-11 years). Forty-seven (52.8%) and 42 (47.2%) patients were in Child-Pugh grade B and C, respectively. Serum Cr and CysC levels and GFR were 0.8+/-0.2 mg/dL, 1.1+/-0.3 mg/L, and 73.4+/-25.5 mL/min, respectively. Significant and severe renal impairment were noted in 28 (31.5%) and 2 (2.2%) patients, respectively. GFR was well correlated with serum Cr, CysC, and e-GFRMDRD, while it was not correlated with e-GFRC&G. In multivariate analysis, only CysC was significantly correlated with GFR (beta, 45.620; 95% CI, 23.042-68.198; P<0.001). Serum CysC level was the only independent predictor for significant renal impairment. CONCLUSIONS: Significant renal dysfunction was not rare in patients with cirrhotic ascites, even their serum Cr level is normal. Serum CysC is a useful marker for detecting significant renal dysfunction in these patients.

Multiple lymphomatous polyposis (MLP) is a term used to describe malignant lymphoma of the gastrointestinal tract that manifest as polyposis. MLP is believed to represent gastrointestinal involvement by mantle cell lymphoma (MCL), primarily based on its histologic and immunophenotypic similarities with MCL. We have experienced a case of MCL presented as a peculiar feature of multiple lymphomatous polyposis in a 49-year old male patient. He had been diagnosed diffuse large B cell lymphoma of nasopharynx and treated by radiation therapy and CHOP chemotherapy. He newly developed MCL after 10 years in complete remission of diffuse large B cell lymphoma. After newly developed lymphoma was compared with former diagnosed lymphoma, we concluded that they were not same type each other. We reviewed a total of 13 patients including this case, of MLP, which were reported in various Korean literature, and literatures are reviewed.

Postganglionic cholinergic dysautonomia is a rare disease characterized by impaired secretion of tears and saliva, generalized absence of sweating, lack of cardiac response to carotid massage and atony of the gastrointestinal tract and urinary bladder. Autonomic function tests show the preservation of sympathetic adrenergic functions in contrast to the generalized involvement of postganglionic parasympathetic and sympathetic cholinergic nerves. Recently, we experienced a patient with gut dysmotility in selective postganglionic cholinergic dysautonomia. She is now being treated with bethanechol and milk of magnesia and has experienced minimal symptom improvement.

Background/Aims: Irreversible electroporation (IRE) is a relatively new ablation method. However, the application of IRE ablation in the treatment of biliary disease has not been attempted. A minimally invasive approach using endoscopic retrograde cholangiopancreatography (ERCP) can be a novel therapeutic modality for IRE ablation. In this study, we aimed to investigate the feasibility of endoscopic IRE for the biliary tract using an animal model. Methods: A new catheter-type electrode was developed for endoscopic IRE ablation of the biliary tract. We performed ERCP and endoscopic IRE ablations in the normal common bile duct of Yorkshire pigs. The experimental setting of IRE was 500 V/cm (50 pulses, 100-µs length). The animals were sacrificed after 24 hr, and the ablated bile duct was examined. Results: Well-demarcated focal color changes were observed on the mucosa of the common bile duct. The depth of change after IRE was confined to the mucosal and submucosal layers. Apoptotic changes in the bile duct were observed only around the IRE ablation area. Immunohistochemistry assay showed cell death in the bile duct along the electrode. Conclusions Endoscopic IRE ablation using ERCP was successfully performed in the common bile duct. It can be a potential option for the treatment of biliary tumors.

Background/Aims: Several attempts have been made to incorporate smart glasses in the medical field. We applied wearable display glasses to show the position of an observer during endoscopy and compared students’ responses between the conventional and new methods. Methods: We surveyed 28 medical students regarding the use of wearable display devices. The students used wearable display glasses to observe an endoscopic procedure and answered the prepared questionnaire. Their collected responses were analyzed for statistical correlations between each variable. Results: The survey of medical students revealed disadvantages including dizziness (dissatisfied and very dissatisfied: 21.5%) and eye fatigue (25% dissatisfied) and advantages including concentration (satisfied and very satisfied: 57.2%) and securing patient rights (71.4%). The students showed more positive than negative reviews regarding the new devices (32.1% vs. 21.5%). Conclusions We investigated the advantages and disadvantages of viewing the endoscope image with new wearable display glasses compared to the conventional method using the survey to record user experience. The results revealed relatively positive responses from the medical students in the survey. If the new device compensates for some shortcomings, its use in the endoscopy room will be feasible.
