The combined products of antacids(AM) composed of aluminium hydroxide, magnesium hydroxide, and simethicone with a ratio of 1 : 1 : 0.1 and aceglutamide aluminium(AGA) were assayed for the antiulcer activity. The effect of the antacids(AM) in concurrent treatment with AGA was studied in acute gastric lesion induced by Shay's method, stress, ethanol, and indomethacin, in chronic gastric ulcers induced by acetic acid, and in duodenal ulcer induced by mepirizole. In all experimental models, the combined treatment of AM and AGA in the ratio of 2.3:1 showed significant potentiation in inhibition against acute gastric and duodenal ulcer and revealed a significant potentiation of the healing of chronic gastric ulcer.

Acute hemorrhagic enteritis was diagnosed in a seven-month-old male Shitzu dog dying of blood stained diarrhea and vomiting. Clinical findings were anorexia, dullness and sudden death after massive bloody diarrhea. At necropsy, main lesion was the hemorrhage in small intestine, mainly duodenum and jejunum. Microscopically, Gram positive long bacilli were massively detected on the mucose epithelial cells and necrotic debris of small intestine. Coagulative necrosis of epithelial cells and thrombosis of small intestine were also identified. However, there was no lesion of crypt epithelium. Mineral infiltration in both gastric mucosa and renal tubules was detected and proliferation of fibrous tissue was also shown in corticomedullary regions. In bacterial examination, C perfringens was isolated in anaerobic culture and it was confirmed to type A by multiplex PCR. Therefore, the dog was diagnosed as C perfringens type A associated enteritis with uremia.

Seizure is a foreseeable risk in patients with brain lesion. However, seizure during treating non-brain lesion is not a familiar situation to neurosurgeon. Posterior reversible encephalopathy syndrome (PRES) is a relatively common situation after systemic chemotherapy. The aim of this study is to make neurosurgeons aware of this potential medical problem. A 52-year-old woman with advanced gastric cancer, presented with low back pain due to spinal metastasis at the 4th lumbar vertebra. Ten cycles of chemotherapy with FOLFOX (5-Fluoruracil/Oxaliplatin) had been completed 23 days ago. Two days before the planned operation, a generalized tonic clonic seizure occurred. She did not have a history of hypertension or seizure. The seizure was stopped with lorazepam 4mg. The brain magnetic resonance (MR) imaging showed high signal changes in both parieto-occipital lobes on the T2-weighted images, and these were partially enhanced, suggesting PRES. The surgery was preceded by treatment with an antiepileptic drug. The MR images, taken 1.5 months after the seizure, showed that the lesion was no longer present. At 3 month follow-up, no additional seizure attack occurred without any seizure medication. The possibility of a seizure attack should be considered if the patient has a history of chemotherapy.

Definitely, treatment for gastric cancer is primarily surgical. Detection in early stage of disease and complete surgical resection is the best way to cure gastric cancer. If surgery is planned, careful preoperative evaluation and corrections of physiologic and psychologic abnormalities are essential to reduce perioperative morbidity or mortality. Basic principle of gastrectomy for gastric cancer is an en bloc resection of tumor with adequate margins of normal tissue and with regional lymph nodes and omental tissues. To complete these principles, regional lymph nodes and all omental tissues should be removed altogether during performing various types of gastric resection. The lymph node dissection is one of the most effective procedures for gastric cancer to achieve curative resection. The basic types of gastric resection are distal subtotal gastrectomy and total gastrectomy according to the condition of primary lesions and the status of lymph node metastases. When the primary lesion is located near the esophagogastric junction, it is sometimes hard for a surgeon to select adequate surgical method. Postoperative quality of life in a patient has become a very important factor to be considered in every step of surgical therapy. With increasing incidence of early gastric cancer, a number of surgical trials for limited surgery or endoscopic procedures have been performed, but the long-term clinical results should be carefully analyzed to define the clinical relevance of these new techniques. For patients with disseminated gastric cancer, a palliative procedure can be performed to improve quality of life of patients and to avoid immediate death due to the cancer-related complications.

Rubus crataegifolius (RC), Ulmus macrocarpa (UM), and Gardenia jasminoides (GJ) are well-known folk medicines in Asia used to treat various gastrointestinal disturbances. The present study evaluated the gastroprotective effect of LS-RUG-com, a mixture of commercially prepared powders of RC, UM, and GJ with a ratio of 3:1:2(w/w/w) against HCl/ethanol-induced gastritis, indomethacin-induced ulcers, and esophageal reflux-induced esophageal mucosal damage and Helicobacter pylori infections. In addition, TNF-α and IL-1β expressions were also determined and measured in esophageal tissue. As to HCl/ethanol-induced gastritis, the LS-RUG-com treatment at a dose of 150 mg/kg showed a remarkable anti-gastritis effect. Regarding indomethacin-induced gastric ulcers, the LS-RUG-com treatment had a significant anti-gastric ulcer effect. Furthermore, in the gastroesophageal reflux disease (GERD) model experiment, the LS-RUG-com treatment resulted in the histological recovery of stomach damage and mucosal injuries. Furthermore, the LS-RUG-com treatment led to an increase in gastric content pH, an increase in mucus protection, and a decrease in gastric pepsin output with a significant decrease in TNF-α and IL-1β. As to the Helicobacter pylori infected animal model, LS-RUG-com had a notable inhibitory effect on Helicobacter growth. The use of RC, UM, or GJ in isolation or the LS-RUG-com treatment as whole had good effects in terms of anti-oxidation, anti-neutralization, gastric acid secretion inhibition, and anti-lipid peroxidation, which supported the use of natural products as systemic gastric protective agents. Our results suggest that the LS-RUG-com might be a significant systemic gastroprotective agent that could be utilized for the treatment and/or protection from gastric disturbances and related damage.

Purpose: Clinical staging of gastric cancer appears to be important more and more for tailored therapy. This study aimed to verify the accuracy of clinical T staging in a low-volume institute. Materials and Methods: We retrospectively reviewed prospectively collected data of gastric cancer patients who underwent resection. A total of 268 patients of gastric cancer were enrolled from March 2004 to June 2012. These demographics, tumor characteristics, and clinical stages were analyzed for identification of diagnostic value of clinical T staging. Results: The predictive values for pT1 of endoscopy and computed tomography were 90.0% and 89.4%, respectively. In detail, the predictive values of endoscopy for pT1a, pT1b, and pT2 or more were 87%, 58.5%, and 90.6%, respectively. The predictive values of computed tomography for pT1a, pT1b, and pT2 or more were 68.8%, 73.9%, and 84.4%, respectively. The factors leading to underestimation of pT2 or more lesions by gastroscopy were the middle third location, the size greater than 2 cm, and younger age. Those for overestimation of pT1 lesion by computed tomography were male, age more than 70 years, elevated type, and size greater than 3 cm. Conclusions: Diagnostic accuracy of early gastric cancer was 90%, which is comparable to those of high volume center. In patients with early gastric cancer, limited gastrectomy or minimal invasive surgery can be safely introduced at a low volume center also. However, the surgeon of low-volume institute should consider the accuracy of clinical staging before extending the indication of limited treatment.

Purpose: Endoscopic resection is widely accepted as standard treatment for early gastric cancer (EGC) without lymph node metastasis. The procedure is minimally invasive, safe, and convenient. However, surgery is sometimes needed after endoscopic mucosal resection (EMR)/endoscopic submucosal dissection (ESD) due to perforation, bleeding, or incomplete resection. We evaluated the role of surgery after incomplete resection. Materials and Methods: We retrospectively studied 29 patients with gastric cancer who underwent a gastrectomy after incomplete EMR/ESD from 2006 to 2010 at Korea University Hospital. Results: There were 13 incomplete resection cases, seven bleeding cases, three metachronous lesion cases, three recurrence cases, two perforation cases, and one lymphatic invasion case. Among the incomplete resection cases, a positive vertical margin was found in 10, a positive lateral margin in two, and a positive vertical and lateral margin in one case. Most cases (9/13) were diagnosed as mucosal tumors by endoscopic ultrasonography, but only three cases were confirmed as mucosal tumors on final pathology. The positive residual tumor rate was two of 13. The lymph node metastasis rate was three of 13. All lymph node metastasis cases were submucosal tumors with positive lymphatic invasion and no residual tumor in the gastrectomy specimen. No cases of recurrence were observed after curative resection. Conclusions: A gastrectomy is required for patients with incomplete resection following EMR/ESD due to the risk of residual tumor and lymph node metastasis.

In order to study the immunohistochemical effects of herbal drug-acupuncture of Radix paeoniae lactiflorae on gastric ulcer induced by HCl-aspirin in rats. this experiment was done by herbal drug-acupuncture to Wisu($B_{21}$). Chung-Wan($CV_{12}$), Chok-Samni($S_{36}$) loci to measure histological features of ulcer lesion, the change of numbers of parietal cell, chief celI, gastrin and somatostatin-immunoreactive cell. The obtained results were as follows; 1. The ulcerative lesions of gastric mucosa were decreased to WiSU($B_{21}$) loci followed by Chung-Wan($CV_{12}$) and Chok-Samni($S_{36}$) loci compared to the control groups. 2. In the numbers of parietal cell, the most remarkable decrease was observed to Wisu($B_{21}$) loci followed by Chung-Wan($CV_{12}$) and Chok-Samni($S_{36}$) loci compared to the control groups. 3. In the numbers of chief cell, the most remarkable increase was observed to Wisu($B_{21}$) loci followed by Chung-Wan($CV_{12}$) and Chok-Samni($S_{36}$) loci compared to the control groups. 4. In the numbers of gastrin-immunoreactive cell, the most remarkable decrease was observed to Wiu($B_{21}$) loci followed by Chung-Wan($CV_{12}$) and Chok-Samni($S_{36}$) loci compared to the control groups. 5. In the numbers of somatostatin-immunoreactive cell, the most remarkable decrease was observed to Wisu($B_{21}$) loci followed by Chung-Wan($CV_{12}$) and Chok-Samni($S_{36}$) loci compared to the control groups.

Purpose: As the proportion of early gastric cancer (EGC) has recently been increased, minimally invasive treatment is currently accepted as main therapy for EGC. Accurate preoperative staging is very important in determining treatment options. To know the accuracy of endoscopic ultrasonography (EUS), we compared the depth of invasion of the tumor with preoperative EUS and postoperative pathologic findings. Materials and Methods: We retrospectively analyzed 152 patients who underwent EUS before laparoscopic gastrectomy. The preoperative EUS results were compared with the pathological findings. Results: The overall proportion of coincidence for depth of invasion between EUS and pathologic results was 41.4%. Univariate analysis showed that the rate of corrected prediction of EUS for tumor depth significantly decreased for the lesions more than 3cm in diameter (P=0.033), and those with a depressed morphology (P=0.035). In multivariate analysis, the depressed type (P=0.029, OR=2.873) and upper lesion (P=0.035, OR=2.151) was the significantly independent factors influencing the inaccurate prediction of EUS for tumor depth. Conclusions: When we decide the treatment modality considering the clinical depth of invasion by EUS, the possibility of discordance with pathologic results should be considered for the lesions located in the upper third of the stomach and with a depressed morphology.

Mesenteric pseudocyst is rare. This term is used to describe the abdominal cystic mass, without the origin of abdominal organ. We presented a case of mesenteric pseudocyst of the small bowel in a 70-year-old man. Esophago-gastro-duodenoscopy showed a 3.5 cm sized excavated lesion on the posterior wall of angle. Endocopic biopsy confirmed a histologic diagnosis of the poorly differentiated adenocarcinoma, which includes the signet ring cell component. Abdominal computed tomography scan showed a focal mucosal enhancement in the posterior wall of angle of the stomach, a 2.4 cm sized enhancing mass on the distal small bowel loop, without distant metastases or ascites in rectal shelf, and multiple gallbladder stones. The patient underwent subtotal gastrectomy with gastroduodenostomy, segmental resection of the small bowel, and cholecystectomy. The final pathological diagnosis was mesenteric pseudocyst. This is the first case report describing incidentally detected mesenteric pseudocyst of the small bowel in gastric cancer patients.
