Colon has the highest bacterial concentration in the gastrointestinal tract. When the colon is perforated, the operator has to decide whether to perform primary closure, resection with anastomosis, proximal colostomy, and exteriorizatoion. In this retrospective study, from October, 1993, through July 1998, 56 patient with panperitonitis due to colon perforation were operated at Ewha womans University medical center. The rectal perforation was limited the intraperitoneal portion. Our cases were divided into two groups. Group I included 34 patients who treated with one step operations of primaryrepair or resection anastomosis. Group II included 22 patients who treated with two step operations of proximal colostomy or exteriorization. The one step operations were performed in 34 patients, proximal colostomy in 21 patients, and exteriorization in 1 patient. There was 13.7% in the incidence of motality and 33.3% in the incidence of morbidity. The Chi-square test was used to evaluate the significance of differences between two groups. Independent risk factors for adverse outcomes were compared and used to analyse the probability for adverse outcomes with respect to the mode of treatmen. The mode of treatment was not dependent on the risk factors. These results suggest that one could select positively primary closure or resection with anastomosis for the treatment of patients with panperitonitis due to colon perforation.

BACKGROUND: Atrial fibrillation (AF), commonly considered as a cardiac embolic source, can itself be induced by stroke. We therefore tried to find and analyze this 'stroke-induced' AF. METHODS: From the Inha University Stroke Registry of the past 2 years, 143 middle cerebral artery (MCA) territorial infarct patients who had been admitted within 48 hours after stroke onset were recruited to participate in the study. Electrocardiograms (EKG) on admission and follow-up during hospitalization were analyzed. Also, MCA infarct was subdivided according to insular involvement by brain imaging. RESULTS: Among 143 MCA territorial infarcts, 38 patients had AF on admission (Rt:21; Lt:17). Of those, insular involvements of the MCA infarct was noted in 32 patients. All the patients had a follow-up EKG and AF disappeared in 3 patients (Rt:2; Lt:1). In the remaining 105 patients, 10 patients subsequently developed new AF within 1 week after hospitalization. All those 10 patients had right-sided MCA infarcts and insular involvements were present in 9 patients. In summary, among the 48 MCA infarct associated with AF, 13 AF (Rt:12; Lt:1) were presumed to be the consequence and not the cause of stroke. CONCLUSIONS: Though human insular stimulation and inactivation studies have suggested that AF would be more common in left insular destructive lesions, it was not always supported in clinical series. From our study, presumed 'stroke-induced' AF was highly associated with right insular lesions. The mechanism of arrhythmogenesis by ischemic stroke might be more complicated than previously expected and, not merely the simple inactivation of an anatomical substrate, the insular cortex.

15 male patients who received total cystectomy with ileal conduit for bladder tumor were reviewed in relation to the incidence of urethral involvement. Of 15 patients six had recurrent transitional cell carcinoma in the urethral remnant among them one (1/15) received subsequent therapeutic urethrectomy and remaining 5 patients underwent delayed therapeutic urethrectomy after confirmation of urethral tumor but 9 of the 15 had only received total cystectomy. We concluded that the remaining urethra might constitute a potential hazard for further tumor formation. We believe that prophylactic urethrectomy is the way to prevent the recurrence of the malignancy who have multiple tumors, concurrent upper tract tumors, and involvement of the trigone or prostatic urethra.

We live in a digital world where a variety of wearable medical devices are available. These technologies enable us to measure our health in our daily lives. It is increasingly possible to manage our own health directly through data gathered from these wearable devices. Likewise, healthcare professionals have also been able to indirectly monitor patients’ health. Healthcare professionals have accepted that digital technologies will play an increasingly important role in healthcare. Wearable technologies allow better collection of personal medical data, which healthcare professionals can use to improve the quality of healthcare provided to the public. The use of continuous glucose monitoring systems (CGMS) is the most representative and desirable case in the adoption of digital technology in healthcare. Using the case of CGMS and examining its use from the perspective of healthcare professionals, this paper discusses the necessary adjustments required in clinical practices. There is a need for various stakeholders, such as medical staff, patients, industry partners, and policy-makers, to utilize and harness the potential of digital technology.

Hallervorden-Spatz disease (HSD) is a rare, progressive, autosomal recessive hereditary disorder characterized by pyramidal and extrapyramidal signs, speech disturbances, mental deterioration and retinal degeneration during childhood or adolescence. In late-onset form after the age of 20, parkinsonian features may be the predominant clinical manifestation. Meanwhile, involuntary tongue movements are rare and poorly understood, which have been reported in tardive dyskinesia, neuroacanthocytosis, chronic epilepsy, and after head trauma. We report a case of a patient with 'fly catcher's tongue' as a major clinical presentation, accompanied with mild parkinsonism, and typical MR findings of HSD.

BACKGROUND: Various studies on the prediction of common bile duct (CBD) stones through preoperative or operative cholangiography have been reported. When CBD stones were suspected due to preoperative screening factors, endoscopic retrograde cholangiopancreatography was done as a first choice and operative cholangiography could be omitted. We want to know the indications of selective cholangiography and the significance of routine operative cholangiography during a simple cholecystectomy. METHODS: The cases of 134 patients who received on open cholecystectomy between Jan. 1995 and Sept. 1997 were reviewed. Twenty-even (27) cases of a choledocholithotomy without cholangiography were discarded from this study. Our cases were divided into two groups: group I included 9 patients who had CBD Stones, which was pathologicaly confirmed by operative cholangiography, and group II included 98 patients who had no CBD Stones, which pathologicaly confirme by operative cholangiography. The predictability of pathologic CBD. was calculated by the factors as the total bilirubin, alkaline phosphatase, AST, ALT, GGT, CBD. diameter by sonography. According to the number of positive screening factors, 3 grades of scoring were imposed in each case. Grade I was the case where 0- screening factor was positive, grade II was the case where 2 screening factors were positive, and grade III was the case where 3 or more screening factors were positive. RESULTS: Eighty-ive (85) cases were grade I, 6 cases were grade II, and 16 cases were grade III. In grade I, only one case had asymptomatic CBD stones, and the negative predictability was 98.8%. In grade II, there were no CBD lesions, and the negative predictability was 100%. In grade III, there were 8 cases of pathologic CBD lesions, and the negative predictability was 50%. CONCLUSIONS: Precise prediction of CBD lesions before a cholecystectomy is of value in deciding whether or not to perform an operative cholangiography. In our study, we graded the patients according to 5 non-nvasive screening factors. In grade I cases, the negative predictability of 98.8% was acceptable for omitting the operative cholangiography. In grade II cases, the negative predictability was 100%, but in these cases, there was the possibility of pathologic CBD Stones. Hence, in these cases, an operative cholangiography may be done, depending on the surgeon's decision. In grade III cases, an operative cholangiography or a preoperative ERCP. is mandatory.

Cardioplegic myocardial protection has become the most popular method for coronary artery bypass surgery. In contrast, we reported 17 consecutive coronary artery bypass operations with ventricular fibrilation, nitroglycerine infusion, and moderate hypothermia. The average patients age was 55 years. 11 patients had stable angina, 4 patients unstable angina, 2 patients varient angina, and 6 patients had prior myocardial infarcation. On cardiac catheterization, the mean LVEDP was 17.32+/-2.13mmHg, EF was 0.67, and abnormal LV wall motion was noted in 5 patients. Premedication usually consisted of hydroxyzine 1~3mg/kg with or without morphine 0.05~0.1mg/kg IM. Induction agents was morphine sulfate, diazepam, lidocaine and pancuronium for muscle relaxant. Maintaninance agents were nitrous oxide, morphine with small dose of halothane or enflurane. Almost all case (15 patient) was infused nitroglycerine 0.5~1.5 microg/kg throughout entire procedure. After bypass, average patient's temperature maintained 25~28 degrees C, and ventricular fibrillation were induced with or without cold saline irrigation around the heart. Average mean arterial pressure were maintained 60~80 mmHg during bypass period. At the end of bypass, if spontaneous beating were not occurred under normal temperature, defibrillation were used. After bypass stop, methylprednisolone were injected in 15 patients. Average anesthetic time was 585 min., surgery time was 529 min, bypass time was 237 min. Arterial blood gas and electrolyte was acceptable range during all period. Complication implicated with anesthesia was myocardial infarction (3 patient), arrhythmia and transient vocal cord paralysis, 1 patient, respectively and no mortality. In all cases the anginal pain was improved.

PURPOSE: Application of a laparoscopic technique to common bile duct explorations has been limited due to technical difficulty. With increased experience and technique, laparoscopic surgery has become a possible option for the treatment of common bile duct stones. The purpose of this study was to assess the usefulness of laparoscopic surgery in the treatment of common bile duct stones. METHODS: Between March 1997 and August 1999, 35 patients with choledocholithiasis were treated with laparoscopic common bile duct exploration (4 had a previous biliary operative history). Intraoperative choledochoscopy was used to remove common bile duct stones. The stones were retrieved by using a saline flush, a basket, or a Fogarty catheter. The impacted stones were destroyed using electrohydraulic lithotripsy. RESULTS: Successful laparoscopic stone clearance was achieved in 33 cases (94.3%), and conversion to open surgery occurred in one case (2.9%). The morbidity was 5.7% without mortality. Two cases of retained stone were treated with postoperative choledochoscopic removal via fistula tract and postoperative endoscopic extraction. CONCLUSION: Laparoscopic common bile duct exploration is feasible and safe in most patients. With increased of experience, laparoscopic common bile duct exploration could be used widely.
