Background/Aims: Percutaneous endoscopic gastrostomy (PEG) has been widely performed for patients who require prolonged tube feeding support. A retrospective study was conducted to evaluate the complications of PEG and determine the predictors of wound infection. Methods: Medical records of 144 cases of PEG that was per- formed between January 1996 and June 2000 were reviewed to examine the types and frequency of complication, difference in wound infection rates according to age, sex, and underlying diseases. We also analyzed the effects of antibiotics prophylaxis on wound infection and the result of culture from wound infection site. Results: In 28 of 144 PEG cases (19.4%), several complications developed after procedure. Wound infection was the most common complication and occurred in 22 of 144 cases (15.3%) and Pseudomonas aeruginosa was the most common pathogenic microorganism. Other complications included bleeding from gastrostomy site, stomal leaks, and gastroesophageal reflux. There was no statistical difference in wound infection rates according to underlying diseases and antibiotics prophylaxis. However, wound infection developed more frequently in diabetes patients (p<0.05). Old age and underlying diabetes were predictors for developing wound infection after PEG in multiple logistic regression analysis. Conclusions: Old age and DM can be predictors of wound infection associated with PEG. (Korean J Gastroenterol 2001;38:23-28)

There have been many researches about the driving mechanism for off-road mobility and the various utilities of rescue robot constantly. In this paper, a new type of driving mechanism for rescue robot which has a variable geometry single-track is introduced to achieve such objectives as surveillance, reconnaissance and rescue activity. It was designed to improve the performance of overcoming stairs and energy efficiency and to minimize its weight and size. We analyzed the design parameters for several steps of climbing stairs and confirm the possibility of realization of presented driving mechanism from various experiments.

N/A Background : Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease of unknown etiology. The disease is relatively common in western countries, but so far, only about 20 cases have been reported in Korea. Thus, the purpose of our prospective study was to evaluate the clinical characteristics of PBC in Korea. Methods : Between October 1994 and February 1999, 16 patients diagnosed as PBC at our department were enrolled in this study. We analyzed these patients for the distribution of age and sex, initial symptoms and signs, associated disorders, laboratory, endoscopic, and radiologic and histologic findings. Results : Of the 16 patients, the ratio of male to female was 1:7 and the average age was 57.5 years. Pruritus (37.5%) was the most frequent presenting symptom followed by xerostomia and xerophthalmia (12.5%), jaundice (6.3%), chronic fatigue (6.3%), melena (6.3%). Associated disorders were Sj gren's syndrome (25%), arthropathy (12.5%), Raynaud's phenomenon (6.3%) and diabetes (6.3%). Abnormalities of liver function were found frequently. Antimitochondrial antibody (100%), antinuclear antibody (31.25%) and rheumatoid factor (31.25%) were found. Long-term administration of UDCA improved both clinical and biochemical signs in most patients, however, 2 patients experienced exacerbation during UDCA therapy. Conclusions : We experienced 16 cases of PBC within a short period. It is expected that we can find these patients more frequently if we suspect this disease in patients with pruritus and unexplained obstructive pattern of liver function abnormality.(Korean. J. Med 59:634-640, 2000)

Extrapancreatic fluid collection is well known comp1ication of pancreatitis. Involvernent of the left perirenal space is extremely rare and it is often difficult to differentiate from the cystic disease of renal and ureteral origin. We present 1 case of pancreatic pseudocyst which is located at the left perirenal space. We did distal pancreatectomy with splenectomy to disconnect the communicating duct frorn the cyst and the huge cyst was drained externally.
