BACKGROUND: Advanced age alone should not be a serious deterrent to surgery. Preoperative evaluation of concomitant illness, operation time, accurate and minimal, but adequate surgery will serve to minimize morbidity and mortality in elderly patients. METHODS: The total number of surgical patients admitted to Kwang Hye Hospital, Pusan, from March 1994 to August 1996 was 3211, and the number of surgical geriatric patients admitted during the same period was 214. Operations were performed on 139 patients. We recorded information about age, sex, anesthesia type, operation time, non malignancy vs malignancy, emergency vs elective "Surgery", coexisting disease, and APACHE II score, and we examined the patients for results affecting postoperative morbidity and mortality. RESULTS: Postoperative complications occured in 55 cases (39.6%), and the operative mortality was 2.2%. The significant factors affecting postoperative morbidity were emergency operation, malignancy and APACHE II score. The operation time and coexisting diseases were not significant. Age had little effect on the postoperative prognosis CONCLUSIONS: Performance of elective surgery and preoperative evaluation of the APACHE II score are important factors.

This study was undertaken in order to estimate the accuracy of disease code of the Korean National Medical Insurance Data and disease the characteristics related to the accuracy. To accomplish these objectives, 2,431 cases coded as notifiable acute communicable diseases (NACD) were randomly selected from 1994 National Medical Insurance data file and family medicine specialists reviewed the medical records to confirm the diagnostic accuracy and investigate the related factors. Major findings obtained from this study are as follows: 1. The accuracy rate of disease code of NACD in National Medical Insurance data was very low, 10.1% (95% C.I.: 8.8-11.4). 2. The reasons of inaccuracy in disease code were 1) claiming process related administrative error by physician and non-physician personnel in medical institutions (47.0%), 2) input error of claims data by key punchers of National Medical Insurer (31.3%) and 3) diagnostic error by physicians (21.7%). 3. Characteristics significantly related with lowering the accuracy of disease code were location and level of the medical institutions in multiple logistic regression analysis. Medical institutions in Seoul showed lower accuracy than those in Kyonngi, and so did general hospitals, hospitals and clinics than tertiary hospitals. Physician related characteristics significantly lowering disease code accuracy of insurance data were sex, age group and specialty. Male physicians showed significantly lower accuracy than female physicians; thirties and forties age group also showed significantly lower accuracy than twenties, and so did general physicians and other specialists than internal medicine/pediatric specialists. This study strongly suggests that a series of policies like 1) establishment of peer review organization of National Medical Insurance data, 2) prompt nation-wide expansion of computerized claiming network of National Medical Insurance and 3) establishment and distribution of objective diagnostic criteria to physicians are necessary to set up a national disease surveillance system utilizing National Medical Insurance claims data.

PURPOSE: To evaluate between DHS and ITST nail (2nd generation) on the treatment of unstable femur intertrochanteric fracture in patients over 70 years old. MATERIALS AND METHODS: 61 cases of unstable intertrochanteric fracture (grouped 37 patients with DHS and 24 patients with ITST) who were taken the operation from Mar. 2003 to Sep. 2007 were analysed regarding to union time, sliding length of lag screws, operation time, blood loss, postoperative complications and functional recovery score by Skovron. RESULTS: The mean union time was 14.7 weeks in study group (ITST). The mean union time was 16.2 weeks in control group (DHS). The lag screw slidings were 7.2 mm in study group and 8.7 mm in control group. The operation times were 57.9 min in study group and 76.9 min in control group. The amount of blood loss were 67.7 ml in study group and 227.4 ml in control group. The complications were 4 cases in study group and 4 cases in control group. The Skovron recovery scores were 76.5% in study group and 73.7% in control group. CONCLUSION: From a practical point of short operation time, less amount of bleeding and less complication, author think that the ITST nail is useful implant for treatment of unstable femur intertrochanteric fracture in patient of old age.

PURPOSE: The purpose of this study was to compare the surgical results between unilateral lateral rectus recession-medial rectus resection (R and R) and bilateral medial rectus resections in recurrent exotropia. METHODS: In this retrospective study, 22 patients with recurrent exotropia of the basic or pseudodivergence excess types were enrolled. In group A (14 patients), unilateral R and R was performed during the first operation, and R and R was performed in contralateral eyes during the second operation. In group B (8 patients), bilateral lateral rectus recessions were performed during the first operation and bilateral medial rectus resections during the second operation. RESULTS: The mean time interval between the first and second operations was 28.9 months (range, 5 to 64 months) in Group A and 59.9 months (range, 35 to 75 months) in Group B, which was a significant difference between the two groups (p=0.006). The success rates at last follow-up after the second operation were 85.7% in Group A and 87.5% in Group B, which was not statistically different between the two groups (p<1.000). CONCLUSIONS: There was no difference in success rate after the second operation between the two groups. Therefore, the operation method for recurrent exotropia can be chosen according to the operator's preference.

PURPOSE: To report a case of refractive change with intraocular pressure change following trauma. METHODS: Changes in intraocular pressure, refractive power, lens thickness, depth of anterior chamber, and axial length of an 8-year-old girl were measured. RESULTS: During the early period after trauma, the patient showed low intraocular pressure and shallow anterior chamber depth. The refractive power changed to transient high myopia. With temporary high intraocular pressure, the refractive power changed to hyperopia and the refractive power recovered toward emmetropia as the intraocular pressure fell to the normal level. Refractive alteration is a result of changes in intraocular pressure and depth of the anterior chamber by cyclodialysis cleft and its adhesion is induced by trauma to the eye. Herein, the authors show evidence for a relationship between refractive change and posttraumatic ocular change.

Since laparoscopic cholecystectomy(LC) was first introduced in early 1990 in Korea, LC is now widely used with an acknowledgement of the benefits of LC.The author retrospectively analyzed 120 patients who were treated by LC and 40 patients who were treated by open cholecystectomy(OC), at the Department of Surgery, Kwang Hye Hospital from Jan. 1992 to July 1995. For the statistical analysis of the variables, student's t-test and ANOVA F-test were used to assess the differences between two groups(p value = 0.05). The obtained results were as follows. 1. The mean age and sex ratio(M:F) between LC and OC group were 48.3-years-old and 1:1.45, 57.6-years-old and 1:3.4, respectively. 2. Associated diseases were observed in 62 patients (51.7%) of the LC group and 23 patients (57.5%) of the OC group. Peptic ulcer and DM were most frequent, respectively. 3. 20 patients (16.7%) had a previous abdominal operation, with appendectomy, the most frequent among them. 4. The operation times(p=0.05), hospitalization stay(p=0.0001), and postoperative hospitalization stay(p=0.0001) were significantly shorter in the LC group than in the OC group. 5. In the preoperative, intraoperative, and postoperative ABGA of the LC group, especially, intraoperative PCO2 was increased due to CO2 retension and metabolic acidosis was developed, intraoperatively. PaO2 was excessively increased due to hyperventilation to correct the metabolic acidosis, intraoperatively. Satistically, intraoperative pH (p=0.0001), PaO2 (p=0.0001), PCO2 (p=0.0001) except bicarbonate (p=0.1987) were significantly changed, compared with preoperative pH or postoperative pH. 6. Operative cholangiography(OPC) was proceeded in 17 patients(14.2%) and concurrent laparoscopic appendectomy was done in 7 patients (5.8%) of the LC group. 7. Postoperative complications were occurred in 19 patients (15.8%) of the LC group. 3 patients (2.5%) were explorated, the remainders were recovered by conservative treatment. 8. On pathologic findings, cholelithiasis and chronic cholecystitis with 105 patients (87.5%) were most frequent in the LC group. In the OC group, cholelithiasis and chronic cholelithiasis with 25 patients (62.5%) were also most frequent, GB empyema with 8 patients (20%), acute cholecystitis with 7 patients (17.5%). Conclusively, laparoscopic cholecystectomy can be safely applied with lower morbidity, shorter operation times, and shorter hospital stay in selected patients.
