Anisakiasis is a accidental parasitic infection caused by nematode larvae belonging to the subfamily Anisakinae when a raw or inadequately cooked fish is ingested. The common clinical symptoms are severe colicky abdominal pain or epigastric full sensation, nausea, vomiting and fever, but hematemesis or melena is very rare. We report a case of a 11-year-old female child who developed severe epigastric pain recurrently for 2 months, and recalled that she had eaten the raw flesh of an Astroconger myriaster. Endoscopic examination showed the whitish worm invading the stomach wall. Clinical symptoms disappeared after endoscopic removal. This study may be the first pediatric case of gastric anisakiasis in korea.

A 5-year-old castrated male Maine Coon cat presented with chronic otitis on the right ear. The clinical signs, scratching and head shaking, were recurrent despite symptomatic treatment, including antibiotics and antifungal agents. Video otoscopic examination and computed tomography (CT) examination revealed a polyp in the right ear canal. The polyp was removed via per-endoscopic trans-tympanic traction (PTT) with a grasping forceps. After treatment, Horner's syndrome occurred in the right eye but spontaneously resolved a week later. The mass was diagnosed as inflammatory polyp with a fibrovascular stroma containing plasma cells, lymphocytes, and neutrophils. All clinical signs were improved, and no recurrence was observed after 3 weeks of follow-up. This case report demonstrates that CT scan is effective in identifying the margin of polyp and PTT technique is non-invasive method for treating inflammatory polyp in cats without severe complications.

We describe a case of a 48-year-old Korean woman who had a subepithelial mass incidentally discovered by endoscopic examination. Endoscopic mucosal resection revealed a well-circumscribed whitish solid mass within the submucosal space. Microscopically, the tumor was comprised of sparse spindle cells in the dense collagenous stroma with several calcifications and lymphoid aggregates. Immunohistochemical analysis showed that the tumor cells are negative for c-kit, smooth muscle actin, desmin, S-100 and CD34. Based on these findings, the tumor was diagnosed with calcifying fibrous tumor.

Endoscopy has been increasingly used in clinical practice and as a standardized examination procedure for gastrointestinal diseases. However, only a few studies on endoscopic screening for evaluating mortality reduction from gastric cancer have been carried out. Even if a high detection rate is obtained in clinical practice, such a rate cannot be directly accepted as evidence providing the effectiveness of cancer screening. Endoscopic screening for gastric cancer is not an exception of possibility to detect overdiagnosis. If detection rate is used for the evaluation of the effectiveness of cancer screening, the possibility of overestimating the effectiveness of cancer screening cannot be ruled out. To avoid the effect of overdiagnosis and confirm the effectiveness of endoscopic screening, mortality reduction from gastric cancer must be carefully evaluated by conducting reliable studies. The burden of gastric cancer remains real and this cannot be ignored in Eastern Asian countries. To determine the best available method for gastric cancer screening, evaluation of its effectiveness is a must. Endoscopic screening for gastric cancer has shown promising results, and thus deserves further comprehensive evaluation to reliably confirm its effectiveness and how its optimal use can be strategically promoted.

Purpose: We are going to establish the efficacy of endoscopic examinations in diagnosing and treating upper GI bleeding in full term neonates. Methods: We retrospectively reviewed newborns who underwent endoscopic examination because of hematemesis from July 1998 to April 2001. Results: Gestational ages were between 38 and 41weeks, and birth weights were between 2,730 and 3,400 gm. Total of 9 patients were reviewed. Endoscopic examination revealed gastric ulcer in 6 cases, multiple erosions in 2 cases and negative finding in 1 case. All 6 gastric ulcers were multiple and among them 2 patients endoscopic hemostatic therapy. No complication due to the procedure was noticed. Five patients recieved transfusions. All 9 cases were cured through conservative and endoscopic therapy without recurrence. Conclusion: The common cause of upper GI hemorrhage in newborns with no preceding disease turns out to be multiple gastric ulcers and the prognosis is good. The endoscopic approach is useful in diagnosing and treating upper GI bleeding in newborns.

A 41-year old woman with dysphagia visited, which was aggravated after eating. On physical examination, there was a palpable mass on the left supraclavicular area. Endoscopic examination revealed a mass on the distal esophagus with irregular mucosa, erythema and a whitish plaque with luminal narrowing. The patient was diagnosed with unresectable esophageal cancer (squamous cell carcinoma, T3N2M1, Stage IV). The patient received CCRT (total 63 Gy) with cisplatin and 5-fluorouracil (5-FU). After CCRT, the patient took an additionally 2 cycles of chemotherapy for consolidation (cisplatin and 5-FU every 4 weeks). After additional chemotherapy, endoscopic examination showed no residual tumor, a chest CT scan revealed that the mass in the distal esophagus had decreased and there was no enlargement of the lymph nodes around the left supraclavicular area. The patient has been in complete remission for 5 years.

Objective : Discal cyst is rare and causes indistinguishable symptoms from lumbar disc herniation. The clinical manifestations and pathological features of discal cyst have not yet been completely known. Discal cyst has been treated with surgery or with direct intervention such as computed tomography (CT) guided aspiration and steroid injection. The purpose of this study is to evaluate the safety and efficacy of the percutaneous endoscopic surgery for lumbar discal cyst over at least 6 months follow-up. Methods: All 8 cases of discal cyst with radiculopathy were treated by percutaneous endoscopic surgery by transforaminal approach. The involved levels include L5-S1 in 1 patient, L3-4 in 2, and L4-5 in 5. The preoperative magnetic resonance imaging and 3-dimensional CT with discogram images in all cases showed a connection between the cyst and the involved intervertebral disc. Over a 6-months period, self-reported measures were assessed using an outcome questionaire that incorporated total back-related medical resource utilization and improvement of leg pain [visual analogue scale (VAS) and Macnab's criteria]. Results : All 8 patients underwent endoscopic excision of the cyst with additional partial discectomy. Seven patients obtained immediate relief of symptoms after removal of the cyst by endoscopic approach. There were no recurrent lesions during follow-up period. The mean preoperative VAS for leg pain was $8.25{\pm}0.5$. At the last examination followed longer than 6 month, the mean VAS for leg pain was $2.25{\pm}2.21$. According to MacNab' criteria, 4 patients (50%) had excellent results, 3 patients (37.5%) had good results; thus, satisfactory results were achieved in 7 patients (87.5%). However, one case had unsatisfactory result with persistent leg pain and another paresthesia. Conclusion : The radicular symptoms were remarkably improved in most patients immediately after percutaneous endoscopic cystectomy by transforaminal approach.

Purpose: Additional surgery is commonly recommended in gastric cancer patients who have a high risk of lymph node metastasis or a positive resection margin after endoscopic resection. We conducted this study to determine factors related to residual cancer and to determine the appropriate treatment strategy. Materials and Methods: A total of 28 patients who underwent curative gastrectomy due to non-curative endoscopic resection for early gastric cancer between January 2006 and June 2009 were enrolled in this study. Their clinicopathological findings were reviewed retrospectively and analyzed for residual cancer. Results: Of the 28 patients, surgical specimens showed residual cancers in eight cases (28.6%) and lymph node metastasis in one case (3.8%). Based on results of the endoscopic resection method, the rate of residual cancer was significantly different between the en-bloc resection group (17.4%) and the piecemeal resection group (80.0%). The rate of residual cancer was significantly different between the diffuse type group (100%) and the intestinal type group (20%). The rate of residual cancer in the positive lateral margin group (25.0%) was significantly lower than that in the positive vertical margin group (33.3%) or in the positive lateral and vertical margin group (66.7%). Conclusions: We recommended that patients who were lateral and vertical margin positive, had a diffuse type, or underwent piecemeal endoscopic resection, should be treated by surgery. Minimal invasive procedures can be considered for patients who were lateral margin positive and intestinal type through histopathological examination after en-bloc endoscopic resection.

Hepatic metastasis of early gastric cancer (EGC) following subtotal gastrectomy with lymphadenectomy is rare. We report the case of a 61-year-old male patient who was diagnosed with EGC that was initially treated using endoscopic submucosal dissection (ESD) and subsequently underwent laparoscopic subtotal gastrectomy. Histopathological examination of the patient's ESD specimen showed a moderately differentiated tubular adenocarcinoma invading the submucosa without lymphatic invasion. The deep margin of the specimen was positive for adenocarcinoma, and he subsequently underwent laparoscopic distal gastrectomy. The patient developed liver metastasis 15 months after the operation and then underwent liver resection. Histology of the resected specimen confirmed the diagnosis of two foci of metastatic adenocarcinoma originating from stomach cancer. Immunohistochemical analysis of the specimen demonstrated overexpression of human epidermal growth factor receptor 2. The patient was treated with trastuzumab in combination with chemotherapy consisting of capecitabine and cisplatin. Twenty-four months after the operation, the patient remained free of recurrence.

Chordoid glioma of the third ventricle is a rare and challenging tumor to surgery because of its unique anatomical location and its close juxtaposition to the neurovascular structures and hypothalamus. The authors report a case of chordoid glioma of the third ventricle in a 43-year-old woman, who presented with headache and somnolence. The tumor was approached by endoscopic transnasal technique with a favorable result. Histopathologic examination disclosed a neoplastic tissue composed of eosinophilic epithelioid cells, mucinous, periodic acid Schiff-diastase positive, extracellular matrix, and scattered lymphoplasmacytic infiltrates. The best treatment option remains controversial. Customarily, the surgical route to remove chordoid glioma is transcranial; however, the undersurface of the optic chiasm and optic nerves preclude an adequate surgical visualization. In contrast, an expanded endoscopic transnasal approach provides a direct midline corridor to this region without any brain retraction.
