1.Arterial Oxygen Desaturation during Non-sedated Diagnostic Gastrointestinal Endoscopy.
Korean Journal of Gastrointestinal Endoscopy 1996;16(1):25-29
We studied arterial oxygen desaturation, using a pulse oximeter, in 132 patients undergoing diagnostic upper gastrointestinal endoscopy to obtain predictive factors of the change. The baseline arterial oxygen saturation (SaO2) level was 98.8+/- 1.2%. During the procedure, oxygen desaturation (SaO2>95%) was found in 90.2% of the patients, Mild oxygen desaturation (95>SaO2>90%) was found in 9.8% of the patients, and there was no severe oxygen desaturation(SaO2<90%). Age(P=0.52), gender(P =0.48), smoking(P =0.71), body mass index(P =0.32), and endoscopy time(P = 0.68) was not related to the degree of oxygen desaturation. These results suggest that oxygen desaturation, which may rarely induce serious cardiopulmonary events, is not frequently observed during non-sedated diagnostic upper endoscopy.

2.Clinical Study on Duodenal Polyps Prevalence Submitted to Upper Gaatrointestinal Endoscopy.
Korean Journal of Gastrointestinal Endoscopy 1995;15(3):471-477
Retrospective studies of duodenal polyps have shown a prevalence of 0.3-4.6% in patients referred to upper gastrointestinal endoscopy, and histologic classification have been inconsistent. A prospective consecutive study was carried out in 3,871 patients referred to diagnostic endoscopy, Sixteen patients had polyps in the first part of duodenum, for a prevalence 0.41%(0.28-0.53%, 95% confidence interval). Fourteen polyps were either inflammatory(thirteen polyps) or ectopic gastric mucosa(one polyp). Two hyperplasitc polyps were founded. All polyps were benign and sessile, and most of polyps(75%) were solitary.

3.A Case of Duodenal Leiomyosarcoma.
Korean Journal of Gastrointestinal Endoscopy 1995;15(3):531-537
Leiomyosarcoma of small intestine is an uncommon tumor, comprising less than 20 percent of all primary malignant tumors of small intestine. Duodenal leiomyosarcoma is rare disease which amount to about 20 percent of all small bowel malignancy but potentially curable tumors often diagnosed at an advanced age, so its five-year survival following resection approximates 50% in reported series. Recently, several cases of leiomyosarcomas of duodenum were diagnosed by hypotonic duodenograhy in Korea. We experienced a woman with duodenal leiomyosarcoma that was diagnosed by endoscopic duodenal biopsy and received currative resection of the tumor(Whipple's operation). We report the case with review of the literatures.

4.Clinical Study of Endoscopic Retrograde Cholangiopancreatography (ERCP) Induced Pancreatitis.
Korean Journal of Gastrointestinal Endoscopy 1996;16(4):591-600
Background/Aims: Pancreatitis is one of the major complications of ERCP. The purpose of this study is to evaluate the incidence rate and risk factors of ERCP- induced pancreatitis. Method: We analysed 99 consecutive patients(45 males and 44 females) undergoing ERCP from March to September, 1994. The level of serum amylase was measured and clinical assessment of pancreatitis was performed before, 24 hour, 48 hour, and 72 hour after ERCP. We defined clidical pancreatitis as combination of elevated amylase level over 2 days with abdomial pain and tenderness.(continue..)

Primary sclerosing cholangitis is a chronic disease of unknown cause, characterized by inflammation and fibrosis of the biliary tree with diffuse multifocal stricture formation. With increasing knowledge of primary sclerosing cholangitis, it is now recognized that in the setting of inflammatory bowel disease, cholangiocarcinoma is a complication of primary sclerosing cholangitis. We recently experienced a case of 41 year old female patient who had Crohns disease associated with primary sclerosing cholangitis and cholangioearcinoma. We report a case of primary sclerosing cholangitis with cholangiocarcinoma with literature review.

Intraluminal duodenal diverticulum (IDD) is a rare congenital abnormality, consisting of a sac-like mucosal lesion in the duodenum. Cases of IDD can present with gastrointestinal bleeding, duodenal obstruction, or pancreatitis. Here, we report a rare case of a 25-year-old female presenting with IDD complicated by duodeno-duodenal intussusception and recurrent pancreatitis. The diagnosis was based on findings from radiologic examinations (CT and MRI), upper gastrointestinal series (barium swallow), and gastroduodenofiberscopy. Laparoscopic excision of the presumed duodenal duplication was performed. The subsequent histopathologic evaluation of the excised sac revealed normal mucosa on both sides, but the absence of a proper muscle layer confirmed the diagnosis of IDD. Radiologic detection of a saccular structure in the second portion of the duodenum can indicate IDD with duodeno-duodenal intussusception as the lead point

A choledochocele is a benign cyst-like herniation of the intramural segment of the distal common bile duct protruding into the duodenal lumen. Cholangiography is essential to demonstrate a choledochocele. Because choledochoceles are often associated with characteristic structual alterations of the papilla of Vater and the peripapillary area, ERCP is helpful in demonstrating a choledochocele. We present the clinical, endoscopic and radiographic (ERCP) findings in a patient with choledochocele.

9.Comparison of Application of Home-use Mechanical Ventilator and Facility-use Mechanical Ventilator for Early Discharge of Patient from Intensive Care Units
Journal of Korean Critical Care Nursing 2025;18(1):13-26
Purpose:
: This study aimed to identify and compare the effects of home-use mechanical ventilator (MV) and facility-use mechanical ventilator on early discharge from the intensive care units (ICUs).
Methods:
: This retrospective study used data from the electronic medical records of 290 patients who underwent MV in the ICU of a tertiary general hospital in Seoul.
Results:
: Significant differences were observed in the length of ICU stay, total number of days of MV application, and length of hospital stay. The length of ICU stay was 30.00±28.14 days in the home-use MV group and 23.74±18.24 days in the facility-use MV group for facility-use (t=2.25, p=.026). The total number of days of MV application in ICU was 24.44±21.86 days in the home-use MV group and 19.35±14.25 days in the facility-use MV group (t=2.35, p=.020). The length of hospital stay was 101.88± 141.81 days in the home-use MV group and 74.24±71.38 days in the facility-use MV group (t=2.10, p=.037). The readmission rates within 72 hours of discharge from the ICU were 2.1% and 2.1%, respectively.
Conclusion
: A facility-use ventilator shortens the length of ICU stay and the total number of days of MV application in the ICU compared with a home-use mechanical ventilator, and it can be safely used for early discharge of patients from the ICU.
