To identify the efficacy of laparoscopic cholecystectomy, we retrospectively analyzed 600 cases of laparoscopic cholecystectomy who were treated at the Department of Surgery, Chung Ang University from September 1990 to December l992. We intentionally divided periods into 3 groups to observe the frequency of morbidity and mortality, early and late complications, duration of operation and postoperative hospitalization with accumulaton of surgical experiences and techniques. The most prevalent age group was 6th decades, male to female ratio was 1: 1.47 and associated diseases were hypertension, obesity, pulmonary tuberculosis in order of frequency and previous abdominal operations were appendectomy, TAH, C-section in order of frequency. The duration of operation was 38.6 minutes and postoperative hospitalization was 6.2 days. The most frequent pathologic diagnosis was chronic cholecystitis. The postoperative complications were noted in 15 cases(2.5%) including 5 cases of bleeding 4 cases of bile leakage. The number of patients who needed parenteral narcotics was decreased in later peiod. According to oral cholecystogram, opacification correlated with duration of operation of laparoscopic cholecystectomy.

BACKGROUND: High dose fentanyl for cardiac surgery in neonates, infants and children can cause severe bradycardia and chest wall rigidity that result in decreased cardiac output and oxygen desaturation due to fixed stroke volume in pediatric patients. To ameliorate the effects of fentanyl, it is common to administer neuromuscular blocking drugs with wanted cardiovascular side effects. This study was designed to compare the cardiovascular variables and oxygen saturation among different muscular relaxants in high dose fentanyl anesthesia. METHODS: Thirty pediatric cardiac patients were allocated randomly into three muscle relaxant groups treated with 0.2 mg/kg pancuronium (n=10), 0.2 mg/kg vecuronium (n=10) or 0.2 mg/kg pipecuronium (n=10) after receiving an initial bolus dose of 25 g/kg of fentanyl. Changes of heart rate (HR), mean arterial blood pressure (MAP), rate-pressure-product (RPP) and oxygen saturation (SpO2) were observed. The same cardiovascular variables were also observed 1 and 2 minutes after the second bolus dose of 25 g/kg fentanyl and compared to the results among muscle relaxants. RESULTS: HR, MAP and RPP decreased significantly (p<0.05) 1 and 2 minutes after injection of the 1st fentanyl, which returned to levels above the control value after administration of pancuronium, vecuronium or pipecuronium. Among muscle relaxants, pancuronium caused the most rapid and significantly high level compared to the control value in HR and MAP. Next was pipecuronium and then vecuronium. In clinical setting, SpO2 was decreased after the 1st fentanyl injection and increased after the injection of muscle relaxants, but not significant statistically. CONCLUSION: In view of hemodynamic changes, pancuronium is most efficient and rapid in returning the hemodynamic variables that was decreased after high dose fentanyl anesthesia in neonates, infants and children whose cardiac output was dependent on HR due to relatively fixed stroke volume.

With advancement of endoscopical instruments and technique, gallstone diseases can be managed with laparoscopic cholecystectomy which has rapidly and radically changed the surgical treatment of gallstone diseases. The ideas of laparoscopic surgery was introduced by Germany gynecologist Semm, in 1967 and was first performed by French surgeon Mouret, Dubois in 1987. Although many reports of early laparoscopic cholecystectomy were excellent, many surgeons want to know the surgical results of laparoscopic cholecystectomy are enough good to perform comparing with the conventional cholecystectomy, especially in early complications and late complications.

8.The Relationship between PaCO2 - PETCO2 Difference and SpO2 in Patients with Congenital Cyanotic Heart Disease.

Korean Journal of Anesthesiology 1999;36(1):69-74
BACKGROUND: In neonates and infants with congenital cyanotic heart disease, venous blood, rich in CO2 and poor in O2, is mixed with pulmonary venous blood at left heart. As a consequence, any given degree of decreases in SpO2 is accompanied by obligatory increase in PaCO2 - PETCO2 difference. This study was designed to evaluate these relationship in 20 pediatric patients. METHODS: After endotracheal intubation with high dose fentanyl and pancuroniun, PETCO2 was measured by capnometer (side stream, sample gas flow rate of 200 ml/min; sampling site at elbow connector area) and SpO2 probe was attached at toe or finger. Observations were made 4 or 5 times before initiation of CPB. Ventilation was controlled by pressure type ventilator, partial rebreathing circuit at frequency of 25-35 breaths/min, an inspiratory time of 25% with an end-inspiratory pause of 10%, and peak airway pressure of 20 +/- 2 cmH2O. RESULT : Mean values of PaCO2 - PETCO2 difference were increased linely with decreases in SpO2. The regression equation is mean (PaCO2 - PETCO2) (mmHg) = 23.9 0.22 mean SpO2 (r= 0.51, p=0.028) CONCLUSIONS: The relationship between PaCO2 - PETCO2 was found to agree with that predicted by theory confirming that in congenital cyanotic heart patients, PaCO2 increases by 2-5 mmHg for every 10% reduction in SpO2. This relationship may be useful when attemping to estimate PaCO2 from PETCO2 in the management of congenital cyanotic heart patients.

BACKGROUND: To reduce the amount of homologous transfusion with its inherent problems of transmission of viral hepatitis, acquired immune deficiency syndrome and others, many institutions use comprehensive blood conservation methods (CBCM) in open heart and major aortic operations. The purpose of this study is to compare the amount and cost of homologous transfusion and the efficacy of coagulation between patients with or without CBCM adoption. METHODS: We prospectively assessed available CBCM of our institution in 20 patients, comparing the requirements of blood products, their cost and the efficacy of blood coagulation with those of another 20 patients similar in age, types of operation, operation difficulty and duration of bypass time retrospectively. RESULT: Fewer whole blood and platelet concentrates were transfused in patients with CBCM (p<0.05). There are no significant differences in the amount of used packed red blood cell and fresh frozen plasma between two groups. Partial thromboplastin time is significantly short in patient with CBCM (p<0.05). The prevalence of complications and mean extra-financial cost for using cellsaver, platelete pheresis and homologous blood products are low in patients with CBCM. CONCLUSIONS: The CBCM requires additional cost won but CBCM reduces the requirements of homologous blood effectively.

BACKGROUND: Residual stones after biliary tract surgery are a formidable task for the surgeon. Choledocholithiasis and hepatolithiasis are more common in East Asia, including Korea, compared with the West, and retained and recurrent stones remain a major problem after the surgical treatment of biliary tract stones; thus, various attempts to reduce the rate of retained and recurrent stones are important in the treatment of biliary tract stones. METHODS: A retrospective analysis was done on 815 cases of patients with biliary tract stones who had undergone an operation at the Department of Surgery, Chung-ng University Hospital, during the 13 years from January 1984 to December 1996. RESULTS: The male-to-female sex ratio was 1 : 2, and the most common age group was the 7th decade. The most common symptoms and physical findings were right upper quadrant pain in 620 cases (76.1%), and right upper quadrant tenderness in 511 cases (62.1%). The most common laboratory findings were elevated alkaline phosphatase (88.3%), followed by elevated sGPT and elevated sGOT. Bile cultures and sensitivity tests were done in 815 cases and were positive in 682 cases (83.7%). The most common bacteria were E.coli in 252 cases (37.0%). The locations of the stones were gallbladder (GB) and common bile duct (CBD) in 420 cases (51.5%), the CBD in 160 cases (19.6%), the CBD and intrahepatic duct (IHD) in 108 cases (13.3%). The most common operative procedure was a cholecystectomy with T-ube insertion, 525 cases (64.4%). Postoperative complications developed in 208 cases (25.6%), and the most common postoperative complication was wound infection, 72 cases (8.8%). The operative mortality was 2.9%, and most common cause of death was sepsis (10 cases). CONCLUSIONS: The authors conclude that interventional therapy, as an initial treatment for residual stones, is a satisfactory treatment where possible. If there are residual stones in spite of the interventional therapy, a reoperation or hepatectomy is required.
