PURPOSE: Stomach cancer is a major cancer in the world as well as in Korea. Helicobacter pylori infection was suggested causing atropic gastritis, but there has been a debate on the association with the gastric adenocarcinoma. We reviewed recent literatures and meta-analyses on the association between Helicobacter pylori infection and the development of gastric adenocarcinoma. PESULTS: The animal experiments suggested that Helicobacter pylori is a causative agent of gastric adenocarcinoma. Meta-analyses on the relationship between Helicobacter pylori infection and gastric adenocarcinoma showed increased risk in infected person, but the strength of association was varied with study design, characteristics of study participants and the nature of tumors. CONCLUSIONS: Recent study results suggested that Helicobacter pylori is a necessary causative agent for development of gastric adenocarcinoma. Assessment of the association between Helicobacter pylori infection and other factors related with gastric cancer risks and the effects of the eradication therapy of Helicobacter pylori infection on the prevention of gastvic cancer need further evaluation.

A huge convexity meningioma close to motor area of the dominant hemisphere was resected completely without any complications and Sequelae. A 50-year-old male patient who has been suffered from dysphasia, focal seizure, recent memory impairment and weakness of the right upper extremity for about three months was admitted to our neurosurgical department on March, 1977. Before admission, he had been treated with acupuncture and conservative managements under the diagnosis of arteriosclerotic cerebral thrombosis at certain famous university hospitals. On examination, he was mentally clear but moderately dysphasic : there were central type of right facial palsy and weakness of right upper extremity with intact sense. Extensor type of plantar response on the right was noted and fundoscopic examination was impossible due to bilateral cataract. Tc-99m pertechnetate brain scan and left carotid angiogram suggested large space occupying lesion of the left parietotemporal area and so large craniotomy on the left side was performed and through this huge meningioma was resected from the left cerebral convexity adjacent motor area without any damage to the cerebral cortex and vessels. After operation, his neurological deficits were improved markedly without any seguelae and complications and he was discharged at the day of third week of operation. Repeated neurological examination on discharge day revealed slightest right facial palsy, no dysphasia, no motor weakness and no any complications and sequelae.

Traumatic granuloma of the larynx is a localized inflammatory response to the loss of mucosa caused by laryngeal trauma. Endotracheal intubation is the most common cause of traumatic granuloma. The granuloma arises from the vocal process of the arythenoid. Recently we experienced four cases of laryngeal intubation granuloma in Hanyang Medical Center. The microhistologic study confirmed granulomatous polyps of the larynx.

Cervical cordotomy via anterior approach without bone graft which is a modified Cloward's method is an effective and simple means of relieving of intractable pain with minimal destruction of bone lower morbidity and mortality. This method consists of an anterior surgical approach to the ventral surface of the cervical cord through a simple discectomy. A transverse incision in the dura mater gives excellent exposure permitting incision of the spinothalamic tracts under direct vision. For bilateral pain both incision are made at the same level of the cord without causing impairment of motor function of the lower extremities or bowel and bladder. This procedure has also many advantages and disavantages as follows ; 1. Cervical cordotomy by the this procedure has a much lower morbidity and fewer complications than the conventional procedure by laminectomy. 2. A more complete section of the spinothalamic tract is possible under direct vision. 3. A differential section of the tract with sparing of sensation in non-painful areas is possible by this procedure. 4. An incidence of the cord trauma can be minimized because the incision is possible without distorsion and traction of the cord during the operation. 5. This procedure without bone graft is simpler than original Cloward's method. 6. An water-tight closure of the dura is difficult but successful results are obtained by using a gelfoam. 7. This procedure above the level of the C3-4 interspace is difficult but possible. 8. A relief of pain below the level of the T3 dermatome is available and there is no good operative candidate when the brachial plexus is involved.

Several cases of the hiccups that occurred after interventional pain procedures have been previously reported. A 34-year-old man had suffered from persistent hiccups that started after epidural and trigger point injection of steroid. His hiccups were stopped during meals and sleep. Furthermore, hiccups did not occur after intravenous or intramuscular steroid injection due to eczema and bronchitis, and after interventional pain procedure that was performed under sedation with midazolam. Hence, we suspected that his hiccups had resulted from a psychogenic cause.

Although tracheal injury after tracheal intubation has been reported often, the formation of acquired tracheal diverticulum as the complications of intubation has not been reported before. In a 57-year-old woman, emergency coil embolization was performed for the treatment of a ruptured cerebral aneurysm. Then, the over-ballooning of an endotracheal tube cuff and deep intubation were observed on a chest X-ray. So, the tube was re-ballooned and re-positioned before surgery. Five hours after extubation in the intensive care unit at postoperative 5 days, a perforation of the tracheal diverticulum wall, leading to subcutaneous emphysema around her neck and pneumomediastinum, was diagnosed using CT and bronchoscopy. The cause of the tracheal diverticulum was suspected over-ballooning of the endotracheal tube cuff because the diverticulum site and size were the same as those of the over-ballooning cuff.

Pseudomyxoma peritonei may result from implantation of benign or malignant tumor in peritoneal cavity and is filled with gelatinous material (termed "Jelly Belly") in abdominal cavity. Its origin is usually an appendiceal or ovarian mucinous adenoma or cystadenocarcinoma, but other primary origin such as uterus, intestine, pancreas and stomach umor have been reported. Generally, pseudomyxoma peritonei is slowly progressive and has low grade malignant potential. This report presents a unusual long term survival after evacuation of 15,000 cc of gelatinous material from abdominal cavity which was the low grade mucinous adenocarcinoma and a review of the current literature, management and new its concept. The origin of pseudomyxoma peritonei of this case was most likely from appendiceal mvcinous adenocarcinoma.

It is common to find cholesterol granuloma in the mastoid antrum and air cells of the temporal bone, but it is very rare in paranasal sinuses, especially in ethmoid sinus. Diagnosis is rarely suspected preoperatively, and depends on the finding of characteristic histological picture. It is currently thought that disturbed ventilation, impaired drainage and hemorrhage play a significant role in the formation of cholesterol granuloma. Five cases with cholesterol granuloma of the paranasal sinus, one that was limited to ethmoid sinus and the others of the maxillary sinuses, are presented and discussed.

BACKGROUND AND OBJECTIVES: Stapedial fixation is most commonly found in congenital anomaly of middle ear. Congenital middle ear anomaly without anomaly of the auricle and inner ear is rare. The surgery of stapedial fixation has evolved during the last 50 years from total to partial stapedectomy, and finally to stapedotomy. Stapedotomy is less likely to induce iatrogenic inner ear lesions and results in better hearing in the higher frequencies than stapedectomy. In recent years, stapedectomy has increasing tendency to be replaced by stapedotomy. This study was carried out to analyse clinical features of stapedial fixation and evaluate the degree of the auditory improvement, and also to analyse the factors affecting the results after stapedotomy. MATERIALS AND METHOD: From Jan. 1992 to Aug. 2001, we analysed 25 cases (23 patients) of stapedotomy operated by one surgeon for stapedial fixation at Asan Medical Center. The clinical features, preoperative and postoperative audiologic findings, postoperative complication and factors affecting the results were analysed. RESULTS: Preoperative mean bone and air conduction thresholds were 26.5 dB, 64.0 dB, respectively and mean air-bone gap was 36.5 dB. After stapedotomy, mean bone and air conduction thresholds were 24.9 dB, 37.0 dB, respectively at the last audiologic follow-up. In one case, sensorineural hearing loss was observed. There were no significant differences of results associated with bilaterality, length of piston wire and con-commitent other ossicular anomaly. CONCLUSION: Stapedotomy is effective and safe for stapedial fixation. But there is a need for carefulness and meticulousness because of complication. There may need various operative trials and larger scale studies to study about factors affecting the results after stapedotomy.
