The study was conducted to compare the side effects in myelography of the two non-ionic water-soluble contrastmedias, Iopamidol(Niopam) and Metrizamide(Amipaque). A total of 111 patients were examined, 64 with Iopamidol and47 with Metizamide. Side effects consisted of headache, nausea, vomiting, dizziness, urinary difficulty, muscularpain, seizure, neurobehavioral distrubance, neurologial sign change, vital sign change and etc. The common sideeffects were headache, nausea, vomiting and dizziness in order of frequency. Most of the side effcts were subsidedwithin 24 hours following meylography. Iopamidol myelography caused fewer and milder side effects than Metrizamidestudy. The side effects were more commonly observed in cervial, thoracic or total myelography than in lumbarmyelography with either lopamidol or Metrizamide. There was no significant correlation between incidence of theside effects and premedication with phenobarbital or valium injection before myelography and CSF sampling duringthe procedure.

Esophagea1 achalasia is a disease of unkown etiology characterized by abscenee of peristalsis in the body of the esophagus and failure of the lower esaphageal sphincter to relax in response to swallow. The cause has been suggested by the lack or abscence of ganglion cell in Auerbach's plexus. About 10% of patients with achalasis develop pulmonary complication such as aspiration pnuemonia, pulmonary fibrosis, pulmonary tuberculosis, culosis, bronchiectasis, lung abscess and bronchial asthma. Although aspiration pneumonia is the most common pulmonary complication in patients with achalasia, lung abscess is the extremely rare complication. A 48 years old female, who has experienced dysphagia and regurgitation for several years, is hospitalized because of high fever, cough and sputurn for 2 weeks. Lung abscess in apicoposterior segment of left upper lobe is observed in X-ray and chest CT. The findings of esophagogram, esophagogastroscopy and esophageal manometry are consistent with achalasia. We report a case of lung abscess associated with achalasia.

BACKGROUND/AIMS: Endoscopic submucosal dissection (ESD) is a novel technique for an en bloc resection of mucosal tumors over 2 cm in diameter. The aim of this study was to evaluate the efficacy, resection time and complications of ESD using a needle knife (needle-ESD) with a comparison those encountered using endoscopic mucosal resection (EMR) after a circumferential mucosal incision with a needle knife (needle-EMR). METHODS: Thirty-three consecutive patients with early gastric cancer or gastric adenoma who underwent needle-ESD at the Asan Medical Center between December 2004 and March 2005 were retrospectively reviewed, and compared with the data from 33 consecutive patients who underwent needle-EMR between March 2001 and June 2001. RESULTS: Both the enbloc resection and complete resection could be achieved by needle-ESD in all the patients, while the corresponding percentages were 76% (en bloc resection, 25/33) and 94% (complete resection, 31/33) in the needle-EMR group. The resection time was longer (22.7 vs. 11.6 min) in the needle-ESD group than in the needle-EMR group. However, there was no significant difference in the complication rate between the two groups. CONCLUSIONS: Compared with the needle-EMR, needle-ESD has significant benefits, particularly regarding the en bloc and complete resection rate despite the technical difficulty and longer resection time.

Helicobacter pylori (H. pylori) has been etiologically linked with primary gastric mucosa-associated lymphoid tissue (MALT) lymphoma and gastric carcinoma; however, synchronous and metachronous development of these two neoplasm is a rare finding. The metachronous development of early gastric cancer following gastric MALT lymphoma is even more exceptional, and less than 10 cases have been reported on the literature. We encountered one case of early gastric cancer which occurred 38 months after the complete remission of H. pylori associated gastric MALT lymphoma. We report here on this case along with a review of the literature.

BACKGROUND/AIMS: ALADIN gene has been known to cause achalasia, alacrima, adrenal abnormalities and a progressive neurological syndrome. A considerable proportion of achalasia patients has been known to show alacrima (decreased secretion of tear). However, the genetic mechanism between achalasia and alacrima has not been defined yet. We postulated that ALADIN gene may be involved in the occurrence of early-onset achalasia; thus, we investigated the correlation of ALADIN gene in early-onset achalasia patients. METHODS: From 1989 to 2007, patients who were diagnosed as primary achalasia before age 35 were enrolled. All of the enrolled patients were asked for (1) blood sampling for DNA, (2) Shirmer test and (3) dysphagia questionnaires. RESULTS: The ALADIN gene in exon 1, 2, 10, 11 and 12 from 19 patients was investigated (M:F = 12:7). The mean age of patients at diagnosis was 27 +/- 5 (15-35) years old. Eight out of 19 (42%) showed alacrima by the positive Shirmer test. In spite of thorough exam in the genetic study, there was no definite abnormal genetic finding in this study. CONCLUSIONS: A considerable number of achalasia patients showed alacrima. Due to the limitation of this study, it is difficult to conclude that early-onset achalasia may have significant correlations with the ALADIN gene.

BACKGROUND/AIMS: Lactobacillus rhamnosus GG (LGG) has been used in acute colitis treatment. However, it is unclear whether the LGG prevents chronic colitis. The aim of this study was to examine the prophylactic effect of LGG on animal colitis, cytokine secretion, and mucin gene expression. METHODS: BALB/c mice (n=64) were exposed to 5% dextran sulfate sodium (DSS) for 7 days followed by 10 days recovery period and repeatedly exposed for 4 days. Then, the mice were devided into three group; group of oral LGG adminstration throughout the recovery and repeated colitis period; PBS group of PBS administration; control group. Colon length, histologic score, tumor necrosis factor-alpha (TNF-alpha), interleukin-10 (IL-10) levels, mucin gene expressions were determined at each period. RESULTS: In acute colitis period, the LGG group showed higher levels of disease activity index (DAI), histologic score, TNF-alpha, IL-10, but shorter colon length, lower levels of mucin gene expressions than the control group. However, in repeated colitis period, the LGG group showed markedly lower levels of DAI and IL-10 but significantly longer colon length than PBS group (p<0.05). There was no difference in the mucin gene expression. CONCLUSIONS: These results suggest that LGG prevents chronic murine colitis. It may be associated with cytokine modulation and competitive inhibition of pathogenic bacteria. However, it may not be related with gene expression.

Enteropathy-associated T-cell lymphoma (EATL) is an unusual primary gastrointestinal lymphoma, particularly associated with celiac sprue. This tumor usually affects the jejunum and grossly presents as multiple circumferential ulcers without the formation of definite tumor masses. Moreover, mesenteric lymph nodes are commonly involved. The patients have typically suffered from abdominal pain, diarrhea, or weight loss whereas some patients may manifest with nonspecific symptoms for a period of years or an acute emergency of perforation, obstruction, or hemorrhage. The clinical course of EATL is very unfavorable and the prognosis is poor. Both celiac sprue and EATL are very rare diseases in Asia, except India and Middle East. We report a 60-year-old male diagnosed as having EATL after segmental small bowel resection, who presented with recurrent gastrointestinal bleeding.

BACKGROUND/AIMS: Endoscopic en-bloc resection of the large colorectal lesions is technically difficult. The aim of this study is to evaluate the usefulness of combined endoscopic submucosal dissection (ESD) and snare resection for treating colorectal lesions. METHODS: We enrolled 23 patients (M:F=14:9, age range: 46~76 years) with 25 colo rectal tumors that were around or above 20 mm in diameter. A combined treatment of ESD and snare resection was performed. RESULTS: The mean size of the 25 lesions was 22.6+/-8.2 mm (range: 15.0~44.0 mm). Ten lesions were laterally spreading tumors and 15 lesions were found in the rectum. On the histopathologic examination, 16 lesions were adenocarcinoma, 2 lesions were villous adenoma, 1 lesion was a villotubular adenoma, 5 lesions were tubular adenoma and 1 lesion was a hyperplastic polyp. The mean resection time was 27+/-22 min (range: 10~91 min). En bloc resection was possible for 19 lesions (76%). Of these, 18 specimens showed clear resection margins and 1 showed a positive deep resection margin. Of the 6 piecemeal resection cases, 2 showed positive lateral resection margins. Therefore, an 88% tumor free resection rate was obtained. CONCLUSIONS: Combined ESD and snare resection may be an effective and safe modality for the resection of large colorectal lesions.

BACKGROUND: Constipation occurs frequently in diabetes mellitus (DM). However, there are few reports that investigated the characteristics of constipation associated with DM. The purpose of this study was to evaluate the clinical features of constipation associated with DM. METHODS: Among constipated patients who visited Asan Medical Center from January 2000 to December 2004, 45 patients with DM (DM group) and 104 patients without DM (non-DM group) were included in this study. We reviewed the clinical presentation, results of anorectal manometry, colon transit time study, and defecogram. We also analyzed the response to biofeedback therapy. RESULTS: The severity of constipation symptoms before treatment was not different between DM and non-DM group. Patients with colon transit time over 56 hours were more frequent in DM group than in non-DM group (21/45, 46.7% vs. 31/104, 29.8% ; p=0.047). Among DM group, colon transit time and the duration of DM showed positive correlation (r=0.431, p=0.003). The resting anal sphincter pressure was significantly lower in DM group than in non-DM group (43.5+/-21.5 mmHg vs. 51.7+/-22.6 mmHg ; p=0.048). The results of defecography were similar between DM and non-DM group. Successful responses to biofeedback therapy were not different between DM and non-DM group (19/34, 55.9% vs. 43/79, 54.4% ; p=0.887). CONCLUSIONS: Slow transit constipation was more frequent in DM group than in non-DM group. The successful responses to biofeedback therapy appear to be similar between DM and non-DM group.
