Gastric lipomas are rare benign submucosal tumors which can present the diagnostic and therapeutic problems. The preferred treattment is observation or local excision. Since preoperative diagnosis and differentation from malignant tumors can be difficult by use of the conventional diagnostic modalities such as X-ray or endoscopic examination, patients are sometimes subjected to more extensive surgical procedures than warranted. As to the diagnosis of submucosal tumors of the upper digestive tract, a newly developed diagnostic modality of endoscopic ultrasonography(EUS) allows us to visuialize the structures underlying the gastrointestinal wall in a noninvasive maneuver, and can contribute to make differential diagnosis and decision of management. Strip biopsy is an endascopic tissue resection technique which permits resection of both mucosal and submucosal tissue regardless of the morphological type of the lesion, because the submucosal saline injections during the procedures make the flat or depressed lesions to be elevated. Now, we report a 56-yr-old female which had a Yamada type I polypoid gastric submucosal lipoma in the antrum, which could be performed the different diagnosis and successful endoscopic removal by endoscopic ultrasonography and strip biopsy.

A new method for combining ultrasonography snd endoscopy, endoscopic ultrasonography (EUS), was developed to improve the diagnostic accuracy of ultrasound by direct image of the target lesion via the gastrointestinal lumen. EUS has the unique ability to provide clear sonographic images of the wall structure of the stomach. This capability can be ultilized in assessing the depth of cancer invasion of the stomach by identifying which layer the ultrasonographic change extends to. However, the depressed types of early gastric cancer(EGC) are often accompanied by ulcerative change in the tumor foci. And the ultrasonographic picture is also influenced by the ulcerative change.

To determine the most effective and tolerable method of preparation with Golytely for colonoscopy, 141 consecutive cases were randomly allocated to drink either 2,000cc(74 cases, Group I) or 4,000cc(67 cases, Group 2), with infusion rate of 1,000cc/h. The reaults were as follows. 1) The rates of effective colonic clearance in group 1 and group 2 was 94.6% and 94.0%, respectively. There is no significance difference between two groups. 2) There was no significant difference in the ingested volume until the first bowel movement and the time required for rectal efflunt to be clear between two groups. 3) Patient acceptance was higher in group 1 than in group 2. 4) Side effects were less noticed in group 1 than group 2, and incraased in body weight (average 0.8 kg) after ingestion of Golytely was observed only in group 2.

Non-operative palliative treatment for malignant colonic obstruction can sometimes be accomplished by the insertion of anorectal tube, endoscopic balloon dilation or endoscopic laser therapy. But these methods have some disadvantages, such as limitaation of activity, need of repetitive treatment and high-risk of perforation. Endoscopic prosthesis is generally accepted as a safe, effective palliative treatment for malignant esophageal stricture, because this method has no above disadvantages. Neverthless, there is only a few experence with endoecopic prosthesis in malignant colorectal stricture over the world. We report two cases which were safely, effectively performed endoscopic prosthesis in palliative treatment for their malignant rectal strictures.

The intravenous administration of midazolam is widely used as sedative premedication for upper gastrointestinal endoscopy. We performed a study to evaluate the effectiveness and safety of midazoiam as premedication for upper gastrointestinal endoscopy. Between June 1995 and October 1995, 112 patients of diagnostic esophago-gastroduodenoseopy were enrolled in the study. The patients were recieved a bolus midazolam 0.~03mg/kg or placebo, followed by typical anesthesia. The blood pressure, pulse and oximeter values were monitored. The systolic blood pressure and heart rate were increased during endoscopy in compared with before premedication, and normalized immediately. There was no significant change of arterial oxygen saturation. Midazolam induced amnesia completely in 49.2% and partially in 27.2%, and all patients were recovered completely in 1 hour. The tolerance score is higher in the midazolam group as compared with the placebo group(p<0.05), and midazolam group would accept the same sedation for repeated endoscopies(p<0.01). We conclude that midazolam has beneficial effects as premedication for upper gastrointastinal endoscopy without significant altteration in cardiopulmonary parameters. This suggest that midazolam may be used more frequently as premedication, especially in the cases of repeated endoscopy.

Tracheopathia osteoplastica is a rare, benign pathologic condition chahacterized the occurrence of numerous cartilage and bony nodules within the tissue of mucosa. We report a case of tracheopathia osteoplastica that involved both larynx and trachea. The patient was 73 years old male and had hoarseness. The neck CT showed thickened and irregular wall of the trachea extending to the level of the carina with multiple calcified nodules and plaques of bony density projecting into the lumen.
