OBJECTIVETo probe into the effect of acupuncture in imaging diagnosis on changing pyloric antrum and duodenal bulb metamorphosis, and provide reliable evidence for confirming pathological characters.

METHODSAmong 30 cases needing image examination, 18 cases had metamorphosis of duodenal bulb and 12 cases had metamorphosis of pyloric antrum. Acupuncture was given at Zusanli (ST 36) with uniform reinforcing-reducing method, and with moderate-strong stimulation. The needle was retained for 2 min. After pressing point Zhongwan (CV 12), changes of image were investigated.

RESULTSAfter acupuncture, the metamorphosis alleviated in 26 cases, with an effective rate of 86.7%.

CONCLUSIONThis method is simple, convenient and objective with no adverse effects.

OBJECTIVEDuodenal salami ulcer is a common disease found on routine endoscopic examination in children. The purpose of the study was to explore the characteristics and the clinicopathological features of duodenal salami ulcer in children and to deepen the understanding of duodenal salami ulcer.

METHODSThe endoscopic results of 117 cases with the duodenal salami ulcer were analyzed. The specimens of gastric antrum and duodenal bulb were subjected to HE and Giemsa staining and were examined for any alteration in histopathology and infection with Helicobacter pylori (Hp). The duodenal mucosa was stained with AB (pH 2.5)/PAS in order to diagnose the duodenal metaplasia.

RESULTSThe major endoscopic finding was a kind of hoarfrost, which was dotty or flaky, covered on the hyperemic and edematous mucosa. The detection rate of this change was 2.29% (117/5 106) of all the endoscopic examinations in children and the rate among cases with duodenal ulcer was 49.2% (117/238). The histopathology was characterized by a heavy infiltration of mainly lymphocytes, plasmocytes and neutrophilic granulocytes, frequently accompanied by superficial erosion. Sixty-one cases were pathologically diagnosed as chronic active duodenitis, superficial erosion in 45; chronic duodenitis in 50; eosinophilic duodenitis in 6. Detection rate of Hp in gastric antrum was 58% (68/117) of all cases. Detection rate of Hp infection and gastric epithelium metaplasia in duodenal bulb was 11.1% (13/117) and 31.1% (37/117), respectively. However, detection rate of Hp in gastric antrum was 25.0% (1 203/4 810) in 4 810 cases of normal duodenal bulb and chronic duodenitis in the same period. Detection rate of Hp in duodenal bulb was 0% and the detection rate of gastric epithelium metaplasia in duodenal bulb was 2.7% (128/4 810). All these detection rates were much higher than those of the specimens collected during the same period with normal duodenal bulb and chronic duodenitis (P < 0.001). Twenty-one cases were reexamined by endoscopy after having been treated with antacids or antacids and antimicrobial agents for 4 weeks. The lesions were healed up and no scars were found.

CONCLUSIONDuodenal salami ulcer in children had a special manifestation of duodenal inflammation or erosion but not a real ulcer. It was caused by the Hp infection in gastric antrum or duodenal bulb and the increase of gastric acids. The therapeutic principles were antacid and antimicrobial agents. The prognosis was good.

BACKGROUND/AIMS: Abdominal pain-related functional gastrointestinal disorder (AP-FGID) is common in children and adults. However, the mechanism of AP-FGID is not clearly known. Recently, micro-inflammation, especially eosinophilia in the gastrointestinal tract, was suggested in the pathophysiology of AP-FGID in adults. The aim of this study was to evaluate the association of gastric and duodenal eosinophilia with pediatric AP-FGID. METHODS: In total, 105 pediatric patients with AP-FGID were recruited and classified into 4 subgroups based on the Rome III criteria. Eosinophil counts in the gastric and duodenal tissues of children with AP-FGID were compared to those from normal pathology references or those of children with Helicobacter pylori infection. Tissue eosinophil counts were also compared among the 4 subtypes of AP-FGID. RESULTS: Eosinophil counts in the gastric antrum and body were significantly higher in children with AP-FGID than normal reference values. Duodenal eosinophil counts were higher in children with AP-FGID, but not significantly when compared with normal reference values. There were no significant differences in eosinophil counts of the stomach or duodenum among the 4 subtypes of AP-FGID. Eosinophils counts in the gastric antrum and body were significantly higher in children with H. pylori infection than in those with AP-FGID. Duodenal eosinophilia was prominent in cases of H. pylori infection, but not statistically significant when compared with AP-FGID. CONCLUSIONS: Our study revealed that gastric eosinophilia is associated with AP-FGID in children, regardless of the subtype of functional abdominal pain. This suggests some contribution of gastrointestinal eosinophils in the development of pediatric AP-FGID.

PURPOSE: The purpose of this study is to assess the efficacy of axial CT imaging and 3D imaging by spiral CTin the detection and evaluation of gastric lesion. MATERIALS AND METHODS: Seventy-seven patients with pathologically-proven gastric lesions underwent axial CT and 3D imaging by spiral CT. There were 49 cases of advanced gastric carcinoma(AGC), 21 of early gastric carcinoma (EGC), three of benign ulcers, three of leiomyomas, and one case of lymphoma. Spiral CT was performed with 3-mm collimation, 4.5 mm/sec table feed, and 1-1.5-mmreconstruction interval after the ingestion of gas. 3D imaging was obtained using the SSD technique, and on analysis a grade was given(excellent, good, poor). Axial CT scan was performed with 5-mm collimation, 7mm/sectable feed, and 5-mm reconstruction interval after the ingestion of water. RESULTS: Among 49 cases of AGC, excellent 3D images were obtained in seven patients (14.3%), good 3D images in 30(61.2%), and poor 3D images in12(24.5%). Among the 12 patients with poor images, the cancers were located at the pyloric antrum in eight cases, were AGC Borrmann type 4 in three cases, and EGC-mimicking lesion in one case. Using axial CT scan alone, Borrmann's classification based tumor morphology were accurately identified in 67.3% of cases, but using 3D imaging, the corresponding figure was 85.7%. In 33 cases receiving surgery, good correlation between axial CT scanand pathology occurred in 72.7% of T class, and 69.7% of N class. Among 21 cases of EGC, excellent 3D images were obtained in three patients (14.3%), good 3D images in 14 (66.7%), and poor 3D images in two (9.5%). The other twocases of EGC were not detected. By axial CT scan, no tumor was detected in four cases, and there were two doubtful cases. 3D images of three benign ulcers were excellent in one case and good in two. 3D images of three leiomyomas and one lymphoma were excellent. CONCLUSION: Combined axial CT imaging and 3D imaging by spiral CT has the potential to accurately diagnose gastric lesions other than AGC Borrmann type 4 or tumors located at the pyloricantrum.

A biliary fistula from the gallbladder can develop as a result of the erosion of stones into the surrounding viscera. An 82-year-old woman with multiple comorbid diseases presented with a persisting discharge from what was thought to be an abscess in the right hypochondrium, which had previously been drained. Sinogram confirmed fistulous communication with the gallbladder and gastric antrum. The fistulous tract was excised together with the gallbladder, and the gastric defect was repaired. The patient made an uneventful recovery.

Duplication cysts are uncommon congenital malformations that may occur anywhere throughout the alimentary tract. The stomach is an extremely rare site of occurrence. Here, we report a case of gastric duplication cyst initially presenting with a gastric submucosal tumor. A 28-year-old man complained of dyspepsia lasting 1 year and upper endoscopy revealed an ellipsoid submucosal tumor at the greater curvature of the antrum. We intended to use the injection-and-cut technique: however, after saline injection, the lesion was dented and impossible to grasp with a snare. Therefore, we decided to perform endoscopic submucosal dissection and removed the tumor without complication. Histopathology revealed a 0.6x0.6 cm-sized duplication cyst, and there has been no recurrence in 2 years.

BACKGROUND/AIMS: Stomach cancer can be easily diagnosed via endoscopy, but also possible to be missed. The aim of this study was to investigate the clinical and endoscopic characteristics of advanced gastric cancers that were not diagnosed based on endoscopic examination. METHODS: We evaluated patients who had newly diagnosed advanced gastric cancer that was undetected via endoscopy within the last six months. RESULTS: Sixteen patients were included in this study. The locations of the cancers were the cardia in six cases, the greater curvature side of the body in eight cases and the antrum in two cases. The histological findings were tubular type adenocarcinoma in 11 cases, with ten cases of moderately to poorly differentiated adenocarcinoma and five cases of signet ring cell type adenocarcinoma. CONCLUSIONS: Even advanced gastric cancer lesions may not be detected during endoscopy. If a patient continues to complain of upper gastrointestinal symptoms, even though endoscopy does not find abnormal findings, repeated endoscopy and/or additional diagnostic studies should be considered.

Plexiform angiomyxoid myofibroblastic tumor (PAMT) is a recently described mesenchymal tumor of the stomach. We report the first case of PAMT in Korea. A 52-yr-old man underwent esophagogastroduodenoscopy due to dyspepsia for 2 yr. There was a submucosal mass with small mucosal ulceration in the gastric antrum. The tumor measured 3.5 x 2.3 cm in size and showed multinodular plexiform growth pattern of bland-looking spindle cells separated by an abundant myxoid or fibromyxoid matrix rich in small thin-walled blood vessels. The tumor cells were negative for CD117 (c-KIT), CD34 and S-100 protein, but diffusely positive for smooth muscle actin consistent with predominant myofibroblastic differentiation. The patient is doing well without recurrence or metastasis for 5 months after surgery. Although there have been limited follow-up data, PAMT is regarded as a benign gastric neoplasm with histological and immunohistochemical charateristics distinguished from gastrointestinal stromal tumor and other mesenchymal tumors of the stomach.

Primary or idiopathic hypertrophy of the pyloric muscle in adult, so called torus hyperplasia, is an infrequent but an established entity. It is caused by a circular muscle hypertrophy affecting the lesser curvature near the pylorus. Since most of the lesions are difficult to differentiate from tumor, distal gastrectomy is usually preformed to rule out most causes of pyloric lesions including neoplastic ones through a pathological study. A 56-yr-old man with a family history of gastric cancer presented with abdominal discomfort of 1 month duration. Upper gastrointestinal endoscopy showed a 1.0 cm sized irregular submucosal lesion proximal to the pylorus to the distal antrum on the lesser curvature. On colonoscopy examination, a 1.5 cm sized protruding mass was noticed on the appendiceal orifice. Gastrectomy and cecectomy were done, and histological section revealed marked hypertrophy of the distal circular pyloric musculature and an appendiceal mucocele. To the best of our knowledge, this is the first case of torus hyperplasia with appendiceal mucocele which is found incidentally.
