Small cell carcinoma of the ovary has been identified as a specific histopathologic entity. The first II cases were reported by Dickersin et a1, 1982, Since then only 80 cases were reported in literature. This rare and highly aggresive melignancy primarily affeets ehildren and young women(10-40) and grows rapidly, with hypercalcemia occuring frequently. Abscence of effective treatment results in early mortality. Recently we have experienced one case of primary sma11 cell carcinoma of the ovary, which is presented with a brief review of the literature.

The etiology of postoperative unconsciousness is p is various in origin. From Jan. 1973 to May 1981, 14 unconscious patients via the emergency room were treated in the intensive care unit at Pusan National University Hospital. The results are summarized as follows: 1) Sex distribution was 5 males and 9 males, and the age distribution was from 7 to 54. 2) The type of surgery were mainly hystrectomy and oophorectomy(6 cases) and the others were appendectomy(4 cases), gastrectomy(1 case), Cholecystectomy(1 case), and anal fistulectomy( 1case). 3) Seven cases were performed under spinal anesthesia, 6 cases were under inhalation anesthesia, and 1 case was done under Ketamine Hcl intravenous anesthesia. 4) On arrival at ICU, 12 patients were fully comatose and the others were semicomatese. 5) Meperidine was injected in 4 cases for the purpose of postoperative pain relief. 6) Ten cases expired, 3 cases recovered and 1 case was discharged without hope.

Treatment of pelvic malignancy persistent or recurrent after surgery, radiation therapy or chemot-herapy presents a difficult therayeutie challenge. Those patients with central recurrence can be considered as candidate for radical resection. However we must consider many factors for the choice of treatment modality for advanced or recurrent pelvic rnalignancy as follows; the size and location of the recurrent cancer, dose of radiation therapy given, general conditions of the patient and the experience of the surgeon. Pelvie exenteration, when appropriate, is suecessful treatment for recurrent or persistent pelvic malignancy; 5-year survivai has been reported to be as high as 50%. We experienced seven cases of pelvic exepteration for pelvic malignancy between Mar. 1990 and Feb. 1993, Accordingly we present the cases with a brief review of the literatures.

BACKGROUND: In pregnant woman, the respiratory system is influenced by the hormonal environment and an enlarged gravid uterus. After delivery of the fetus, and contraction of the uterus, changes in the respiratory system produced by the mechanical effect of the gravid uterus may decrease or be reversed. We designed this study to observe changes in the respiratory mechanics in pregnant woman under general anesthesia for cesarean section. METHODS: 15 pregnant women at term, ASA 1 were studied. Induction was performed with thiopental/succinylcholine and maintained with O2, N2O and enflurane until delivery. Just before delivery, enflurane was discontinued. Vecuronium was given at 0.1 mg/kg iv 4 min after induction, and after delivery, 1 mg was given as needed. Inspired tidal volume, expired tidal volume, inspired minute ventilation, expired minute ventilation, airway peak pressure, plateau pressure, expired volume during the first 1 second/expired tidal volume (V1.0), dynamic compliance and end-tidal CO2 were continuously measured just after induction, at delivery and 5, 10, 15, 20, 25, 30, 40 and 50 min after delivery. Blood pressure, heart rate and oxygen saturation were also measured. RESULTS: Compared to the value after induction, values after delivery showed no significant changes in inspired tidal volume or minute volume, but significantly increased in expired tidal volume and minute volume and dynamic compliance, and a significant decrease in airway peak pressure, plateau pressure, V1.0 and end-tidal CO2. Blood pressure and heart rate increased significantly after induction, compared to before induction. Oxygen saturation was maintained at 99-100%. CONCLUSIONS: After delivery, the effects of the gravid uterus on the respiratory system rapidly disappeared, in particular changes of pressure in the airway preceded the respiratory volume changes.

BACKGROUND: Sevoflurane is characterized by the lack of an unpleasant odor, airway irritation and its low blood/gas partition coefficient (0.68), which provides rapid and smooth induction. Inhaled induction with sevoflurane is commonly used in pediatric patients, but not in adult patients. This study was designed to investigate the time to completion of LMA insertion and end-tidal sevoflurane concentration during induction with sevoflurane 8% and N2O 50%, after midazolam administration, in adults. METHODS: Twenty eight patients, aged 20(-60) years, were administered intravenous midazolam 30 microgram/kg and after one minute, sevoflurane 8% and N2O 50% were inhaled with tidal-volume breathing. One minute after loss of consciousness, jaw thrust and mouth opening were checked and an LMA was inserted. The end-tidal concentration of sevoflurane, and the times to loss of consciousness and completion of insertion were recorded. The mean arterial pressure and heart rate were also recorded. RESULTS: From initiation of sevoflurane and N2O inhalation, it took 48 +/- 14 seconds until loss of consciousness, and 143 +/- 19 seconds until the completion of LMA insertion. The end-tidal sevoflurane concentration was 4.1 +/- 0.6% at loss of consciousness, 5.0 +/- 0.7% at one min after loss of consciousness, and 4.1 +/- 0.5% after LMA insertion. In all patients LMA insertion was successful and satisfactory. After LMA insertion, compared to baseline, the mean arterial pressure was reduced and the heart rate increased. CONCLUSIONS: After small-dose of midazolam, inhaled induction with sevoflurane 8% and N2O 50% allowed successful and satisfactory LMA insertion in adults.

BACKGROUND: Transversus abdominis plane (TAP) block is a new regional anesthetic technique for postoperative pain control after lower abdominal surgery. We evaluated the analgesic efficacy of ultrasound-guided (US-) TAP block in patients undergoing lower abdominal surgery. METHODS: Thirty American Society of Anesthesiologists physical status I or II patients between 20-80 years of age undergoing lower abdominal surgery were randomized to receive standard care (n = 15) including intravenous patient-controlled analgesia (IV-PCA), or to undergo bilateral US-TAP block adjunctively (n = 15). A standard general anesthetic technique was used. After induction of anesthesia, bilateral US-TAP block was performed using total 30 ml of 2% lidocaine. Each patient was assessed postoperatively at 20, 30, and 60 min in postanesthesia care unit (PACU) and at 6, 12, and 24 h in ward for pain scores using verbal numerical rating scale (VNRS), analgesic requirements, quality of sleep, and complications. RESULTS: US-TAP block significantly reduced VNRS pain scores at 20, 30, and 60 min postoperatively (P < 0.001). The US-TAP block group required significantly fewer remifentanil intraoperatively (P < 0.05). Additional analgesic requirements were significantly lower in both PACU and ward (P < 0.05) in the US-TAP block group. There were no statistically significant between-group differences in total infused volume of IV-PCA, time to first requirement of analgesics in ward, and quality of sleep. CONCLUSIONS: US-TAP block with 2% lidocaine provided superior analgesia after lower abdominal surgery especially in the first 60 postoperative min when used as a component of a multimodal analgesic regimen.

Fat embolism syndrome is a rare and potentially lethal complication most commonly seen in long bone fractures and intramedullary manipulation. The clinical triad of fat embolism syndrome consists of mental confusion, respiratory distress, and petechiae. This study reports a case of cerebral fat embolism syndrome following elective bilateral total knee replacement. After an uneventful anesthesia and initial recovery, the patient developed neurologic symptoms nine hours postoperatively.

BACKGROUND: Benzodiazepines have a hypnotic/sedative effect through the inhibitory action of gamma-aminobutyric acid type A receptor. Flumazenil antagonizes these effects via competitive inhibition, so it has been used to reverse the effect of benzodiazepines. Recently, flumazenil has been reported to expedite recovery from propofol/remifentanil and sevoflurane/remifentanil anesthesia without benzodiazepines. Endogenous benzodiazepine ligands (endozepines) were isolated in several tissues of individuals who had not received benzodiazepines. METHODS: Forty-five healthy unpremedicated patients were randomly allocated to either flumazenil or a control groups. Each patient received either a single dose of 0.3 mg of flumazenil (n = 24) or placebo (n = 21). After drug administration, various recovery parameters and bispectral index (BIS) values in the flumazenil and control groups were compared. RESULTS: Mean time to spontaneous respiration, eye opening on verbal command, hand squeezing on verbal command, extubation and time to date of birth recollection were significantly shorter in the flumazenil group than in the control group (P = 0.004, 0.007, 0.005, 0.042, and 0.016, respectively). The BIS value was significantly higher in flumazenil group than in the control group beginning 6 min after flumazenil administration. CONCLUSIONS: Administration of a single dose of 0.3 mg of flumazenil to healthy, unpremedicated patients at the end of sevoflurane/fentanyl anesthesia without benzodiazepines resulted in earlier emergence from anesthesia and an increase in the BIS value. This may indicate that flumazenil could have an antagonistic effect on sevoflurane or an analeptic effect through endozepine-dependent mechanisms.

BACKGROUND/AIMS: Patients undergoing Billroth II (B II) gastrectomy are at higher risk of perforation during endoscopic retrograde cholangiopancreatography (ERCP). We assessed the success rate and safety of forward-viewing endoscopic biliary intervention in patients with B II gastrectomy. METHODS: A total of 2,280 ERCP procedures were performed in our institution between October 2008 and June 2011. Of these, forward-viewing endoscopic biliary intervention was performed in 46 patients (38 men and 8 women with B II gastrectomy). Wire-guided selective cannulations of the common bile duct using a standard catheter and guide wire were performed in all patients. RESULTS: The success rate of afferent loop entrance was 42 out of 46 patients (91.3%) and of biliary cannulation after the approach of the papilla was 42 out of 42 patients (100%). No serious complications were encountered, except for one case of small perforation due to endoscopic sphincterotomy site injury. CONCLUSIONS: When a biliary endoscopist has less experience and patient volume is low, ERCP with a forward-viewing endoscope is preferred because of its ease and safety in all patients with prior B II gastrectomies. Also, forward-viewing endoscope can be used to improve the success rate of biliary intervention in B II patients.
