미 연방 노동성이나 인디아나주 노동성 통계에 의하면 산업사회에 근무하는 인력의 10퍼센트 정도는 질병이나 사고로 매년 병원을 찾게 된다. 그중 90퍼센트는 일반 의학으로 치료되어 다시 직장으로 돌아가게 된다. 그러나 나머지 10퍼센트는 재활 의학의 도움이 필요하다. 재활 의학의 도움을 받는 환자 중 70퍼센트는 완전 재활이 되어 전 직장으로 돌아가며 나머지 15퍼센트는 직업을 변경해야하고 15퍼센트는 직업 재활이 불가능한 것으로 나타나고 있다. 재활 치료의 종류는 종합 재활 진단과 평가, 종합 재활 치료와 직업 재활 치료가 있다. 산재로 인한 환자는 이 중 하나 또는 그 이상의 재활 치료를 받는다. 본 연구에서는 연방과 인디아나주의 통계를 기초로 서북 인디아나 지역 산업 재해로 인한 환자를 산출하고 재활 의학으로 그들을 재활 시키는데 필요한 시설, 재정 그리고 전문 인력을 조사하였다. 이들을 재활 시키기 위해 드는 비용과 재활병원이 벌어들이는 수입이 비교 되었음은 물론 이들을 재활 시키지 않아서 지출해야 하는 재정과 재활을 시키는데 필요한 재정이 비교 고찰되었다. 요켄데 피할 수 없이 일어나는 산업사회의 사고에 의한 환잘들의 재활 의학 치료는 당사자들은 물론 국가, 사회와 재활 병원을 위해서도 경제적 이익을 가져 올 수 있다.

N/A Esophageal pressure was compared between esophageal varix and control group and also between before and after transection of the esophagus in variceal patients. Different types of non-shunt operations were perfomried on 157 esophageal varix cases from January 1979 to June 1992. The LES (lower esophageal sphincter) pressure was hiigher in variceal patients than in control group and it was decreased after transection of the esophagus. There were no significant differences in the amplitude and duration of the esophageal contractions between the esophagal varix and control group. The same was true before and after the transection. Of the 157 patients, 116 were male and 4l were female with ratio 2.8:1 and 81.6% were between 30 and 59. Of the 157 operations 80 were Sugiura operations, 61 were Kobayashi operations, 11 were TEPG and 5 were Hassab operations. Operative. mortality rates of prophylactic, elective and emergency surgery were 4.5%, 8.5% and 35%., respectively and of Childs criteria A, B and C werc 1.7% 11.3% and 28.6%, respectively. Of the total 135 intraoperative wedge liver biopsies, 108 cases revealed cirrhosis (80.6%), 12 cases chronic inflammation, 11 cases fibrosis and in 3 cases, no pathologacal findings were found. Postoperative complications include wound infection (21 cases), pleural effusion (17 cases), rebleeding (8 cases), esophageal leakage (5 cases), esophageal stenosis (5 cases) and others. The overall rnortality within one month after the surgery was 10.8% (17 cases) and the major causes of death were hepatic failure (,9 cases) and rebleeding (5 cases). Follow up esophagograms were obtained in 103 patients and in 45 patients varices disappeared compietely and in 50 patients, there were significant improvements.

N/A Objectives: The present study was performed to evaluate change of orocecal transit time(OCTT) in patients with dysmotility-like functional dyspepsia (DLFD) in a view of whole gut concept. Methods 130patients with DLFD and 47normal controls were measured OCTT at Dongsan hospital from February 1993 to September 1994. OCTT was measured after ingestion of semisolid meal including potato soup and lactulose syrup 20g. OCTT was de- fined as time to reach 10ppm above baseline H2 concentration in duplicate of expiratory HR concentration with 10minutes interval for 3hours. Delay of OCTT was defined as excess of mean +2 SDs of nor- mal controls. Results: OCTT in patients with DLFD was significantly delayed than normal controls (99.9±31.6(SD) min, vs 81.9±13.3(SD) min., p<0.001). Delay of OCTT was observed in 33.9% (48cases) of 130patients with DLFD. Conclusion: OCTT using a semisolid lactulose hydrogen breath test was delayed and could be one of useful diagnostic tests in patients with DLFD. However, comparative study with gastric emptying time should be undertaken simultaneously.

N/A Objectives: The present study was undertaken to compare esophageal manometric findings before and after pneumatic dilatation and to determine whether manometric changes can be useful for evaluation of therapeutic response. Methods: Sixteen patients with primary achalasia were examined esophageal manometry with solid state catheter before and 2 months after pneumatic dilatation using the Rigiflex achalasia balloon dilator 35 mm. Results : Lower esophageal sphincter pressure was decreased from 45.5±16.2 mmHg to 19.7±6.2 mmHg and the gradient between intraesophageal pressure and gastric baseline pressure was reversed from 11.8±7.2 mmHg to ?2.6±3.9 mmHg (p<0.001), Lower esophageal sphincter relaxation and partial return of esophageal peristalsis were observed in 50% and 31.2% of cases respectively after dilatation, compared to 12. 5% and 0% before dilatation. Conclusion: Esophageal manometric parameters changed significantly, which could be usefull for evaluation of therapeutic response after pneumatic dilatation in patients with primary achalasia. However, longterm follow up study should be done in larger number of patients.

N/A Lactulose hydrogen breath test has been used for rneasurement of orocecal transit time (OCTT) because of its non invasiveness and simplicity. Recently, the lack of reproducibility of OCTT which measured by hydrogen breath test using water diluted lactulose resulted in the need to develop a new semisolid or solid meal combined lactulose hydrogen breath test. We measured OCTT in 47 norrnal subjects(male 17, female 30, age 24 69 years, average 35.5 years) after ingestion of semisolid meal including potato soup and lactulose syrup 20g. OCTT was defined as the time from test meal ingestion to a sustained increase of more than 10pprn above the baseline in end expiratory hydrogen concentration with 10 minutes interval for 3 hours. OCTT was 79.2+11.9(mean+SD) minutes in male, 81.5+15.2 minutes in female, and average 81.9+13.3 minutes. Although there was no significant difference according t,o sex, OCTT in sixth and seventh decades were delayed compared to third decades(P<0.05). These results will be useful for comparison of OCTT in different group of patients.(Korean J Gastro- enterol 1994; 26: 619 624)

N/A Objective: This study was undertaken to evaluate the therapeutic effect of endoscopic balloon dilatation in patients with benign and malignant esophageal strictures. Methods: 125 endoscopic dilatations with Rigiflex® TTS Balloon Dilator were performed in 47 patients with benign and malignant esophageal strictures in Keimyung University Dongsan Hospital from January 1992 to December 1993. 33 patients with benign strictures included caustic damage (16/33), postoperative (14/33), esophageal ring (1/33), and reflux esophagitis (1/33). 14 patients with malignant strictures included intraluminal esophageal cancer (12/14) and external compressive cancer of lung and breast (2/14). Results: The results of endoscopic balloon dilatation in 33 patients with benign esophageal strictures were Good in 21 cases, Fair in 9 cases and Poor in 3 cases. The results of 14 patients with malignant esophageal strictures were Good in 8 cases, Fair in 3 cases and Poor in 3 cases. The symptomatic improvement of benign and malignant strictures was shown in 90.9% and 78.6%, respectively. Conclusion: Endoscopic balloon dilatation is a safe, simple, and effective method for primary treatment of benign and malignant esophageal strictures.

N/A Gastric emptying study has an important role in patients with gastrointestinal functional disorders without demonstrable mechanical or mucosal abnormalities. Although several meth- ods for detection on gastrointestinal functional disorders are well known, non-invasive scintigraphic technique using a Gamma Camera is taken as a gold standard at present. A Dual-Head Gamma Camera coupled to a computer was used in 20 normal subjects after in- gestion of the mixture of ''T,-labelled scrambled egg in order to determine gastric emptying time. Four values including lag time, T,,(half gastric emptying time), remnant 1 hour, remant 2 hours were taken at all ages. In the female half gastric emptying time and lag time was slightly shorter, and the amount of remnant radioactive counts at one and two hours was smaller than the I,aale without significant difference. Delayed gastric emptying time was above 109. 9 minutes of half gastric emptying time when defined as excess of Mean+ZSD. W e believe this study using a Dual-Head Gamma Camera can be useful for establishment of more accurate gastric emptying study.(Korean J Gastroenterol 1994; 26: 2Z4 229)
