PURPOSE: Laparoscopic cholecystectomy has become the standard modality of acute and chronic gallbladder disease. This study was performed to evaluate a change in the indication for laparoscopic cholecystectomy according to period by analyzing our experiences. METHODS: We retrospectively analyzed 2,096 cases of laparoscopic cholecystectomy that were treated at the Department of Surgery, Dong-A University. They were divided into 3 groups from October 1992 to December 1996 (Group 1), from January 1997 to December 2001 (Group 2) and from January 2002 to March 2007 (Group 3). RESULTS: The mean age was 50.14+/-13.89 years and the male-to-female ratio was 1 : 1.23. Previous abdominal surgery was noted in 12.24% from Group 1, 14.96% from Group 2 and 21.48% from Group 3. Chronic cholecystitis was the most common pathologic diagnosis in all cases. However, while the incidence of acute cholecystitis and gallbladder empyema in Group 1 was 3.36% and 0%, that of Group 2 was 12.52% and 3.88% and that of Group 3 was 31.79% and 7.59%, which was increased. The mean operation time of each group was 101.00+/-51.00, 69.86+/-40.55, 78.01+/-45.55 minutes (P<0.05). The conversion rate of each group was nine cases (6.04%), 21 cases (3.02%), and 51 cases (4.07%). The surgical complication rate was 7.38%, 3.88% and 4.71%, respectively. The length of hospital stay was 6.08+/-3.65, 3.16+/-2.99 and 2.91+/-3.34 days, which was significantly decreased (P<0.05). CONCLUSION: As surgical experience increased and laparoscopic surgical skills developed, the indication for laparoscopic cholecystectomy changed. The results of this study showed that laparoscopic cholecystectomy was feasible for the treatment of complicated gallbladder lesion.

3.Significance of Follow-up Examination of Tumor Markers after a Radical Gastrectomy in Gastric- cancer Patients.
Journal of the Korean Gastric Cancer Association 2003;3(2):104-111
PURPOSE: The prognostic significance of peri-operative serum carcinoembryonic antigen (CEA) and carbohydrate antigen (CA)19-9 determination in patients with gastric cancer has been controversial. This study was performed to evaluate the significance of CEA and CA19-9 as clinical predictors of prognosis. MATERIALS AND METHODS: The correlations between peri-operative serum CEA/CA19-9 levels and clinicopathologic factors were evaluated retrospectively in gastric cancer patients who had undergone curative surgery during the period from January 1995 to December 1998 at the Department of Surgery, Yonsei University College of Medicine. RESULTS: The positive rates for CEA and CA19-9 were 17.9% and 18.4%, respectively. The CEA positivity was related to the depth of invasion (P=0.040), lymph-node metastasis (P=0.000), and stage (P=0.001). The CA19-9 positivity was significantly related to the depth of invasion (P=0.000), lymph-node status (P=0.000), and stage (P=0.000). The positive rate of combined assay of pre-operative CEA and CA19-9 was 30.0%. There were statistically significant correlations with stage, depth of invasion, or degree of lymph- node metastasis in the combined assay. The survival rates according to the positivity of CEA and to the positivity of CA19-9 were clearly different (P=0.000). CONCLUSION: It should be stressed that even a simple blood test prior to surgery could be useful in establishing the depth of invasion, the status of lymph-node involvement, and the prognosis. For improved survival, an aggressive lymphadenectomy and adjuvant chemotherapy should be considered for patients with positive levels of pre-operative CA19- 9.

Diabetic and nondiabetic vascular diseases cause significant foot problems and it frequently progress to osteomyelitis and amputation. Advances in vascular surgical techniques, including distal arterial bypass via synthetic grafts or autogenous vein grafting have opened the way for higher rate of limb salvage. We have experienced patients with ischemic vascular foot disease and combined skin ulceration and varing degree of soft tissue defect. In three patient with major vessel obstruction, we could preserve limb and avoid major amputation using greater saphenous vein graft with or without microvascular free tissue transfer.

OBJECTIVE: Although anterior cervical discectomy and fusion (ACDF) is the standard treatment for degenerative cervical disc disease, concerns regarding adjacent level degeneration and loss of motion have suggested that arthroplasty may be a better alternative. We have compared clinical and radiological results in patients with cervical disc herniations treated with arthroplasty and ACDF. METHODS: We evaluated 53 patients treated for cervical disc herniations with radiculopathy, 21 of whom underwent arthroplasty and 32 of whom underwent ACDF. Clinical results included the Visual Analogue Scale (VAS) score for upper extremity radiculopathy, neck disability index (NDI), duration of hospital stay and convalescence time. All patients were assessed radiologically by measuring cervical lordosis, segmental lordosis and segmental range-of-movement (ROM) of operated and adjacent disc levels. RESULTS: Mean hospital stay (5.62 vs. 6.26 days, p<0.05) and interval between surgery and return to work (1.10 vs. 2.92 weeks, p<0.05) were significantly shorter in the arthroplasty than in the fusion group. Mean NDI and extremity VAS score improved after 12 months in both groups. Although it was not significant, segmental ROM of adjacent levels was higher in the fusion group than in the arthroplasty group. And, segmental motion of operated levels in arthroplasty group maintained more than preoperative value at last follow up. CONCLUSION: Although clinical results were similar in the two groups, postoperative recovery was significantly shorter in the arthroplasty group. Although it was not significant, ROM of adjacent segments was less in the arthroplasty group. Motion of operated levels in arthroplasty group was preserved at last follow up.

BACKGROUND: Prolongation of the QTc interval is a risk factor for ventricular tachycardia, ventricular fibrillation, especially torsades de pointes, and sudden death. It is associated with increasing age, female sex, some of antiarrhythmic drugs, tricyclic antidepressants, and conditions such as hypokalemia, hypothermia, subarachnoid hemorrhage, congenital long QT syndrome. Earlier studies reported lengthening of the QTc interval with increasing body mass index (BMI) and intra-abdominal fat. But no such reports exist in Korea. Therefore, we determined the relationship between BMI and the QTc interval. METHODS: The study population consisted of 372 persons who undertook periodic health examination in a university hospital between September and December 1998. BMI and standard 12-lead electrocardiogram were measured in all subjects. Excluding 4 patients who had arrhythmia where QTc interval could not be calculated, the QT interval was measured in the electrocardiogram of 368 subjects. The QT interval was measured in the leads that showed the longest interval for three consecutive beats and then were averaged. Correlation between the calculated QTc interval and BMI was examined. The QTc interval difference according to sex and obesity was also analyzed. RESULTS: Among 368 subjects, there were 197 men (54%) and 171 women (46%). The mean ages were 44.5 years for men and 47.6 for women. The BMI was 23.8 3.13 (mean SD). Obese subjects with BMI above 27 kg/m2 totalled 61 (17%), including 31 men and 30 women. The QTc interval was 399 25 msec (mean SD), and the subjects showed prolonged QTc intervals of 24 (12 men and 12 women). There was a statistically significant correlation between BMI and QTc interval (r=0.135, P=0.0094), and the obese subjects were found to have a longer QTc interval than the nonobese controls. Women also had a longer QTc interval than men. CONCLUSION: There was a significant correlation between BMI and QTc interval, and longer QTc interval was observed in obese patients. The QTc interval should be considered when analyzing electrocardiogram of obese patients.

PURPOSE: We sought to evaluate the feasibility and outcomes of laparoscopic resection of giant hepatic cysts and surgical success, focusing on cyst recurrence. METHODS: From February 2004 to August 2011, 37 consecutive patients with symptomatic hepatic cysts were evaluated and treated at Dong-A University Hospital. Indications were simple cysts (n = 20), multiple cysts (n = 6), polycystic disease (n = 2), and cystadenoma (n = 9). RESULTS: The median patient age was 64 years, with a mean lesion diameter of 11.4 cm. The coincidence between preoperative imaging and final pathologic diagnosis was 54% and half (n = 19) of the cysts were located in segments VII and VIII. Twenty-two patients had American Society of Anesthesiologists (ASA) classification I and II, and nine had ASA classification III. Surgical treatment of hepatic cysts were open liver resection (n = 3), laparoscopic deroofing (n = 24), laparoscopic cyst excision (n = 4), laparoscopic left lateral sectionectomy (n = 2), hand assisted laparoscopic procedure (n = 2), and single port laparoscopic deroofing (n = 2). The mean fellow-up was 21 months, and six patients (16%) experienced radiographic-apparent recurrence. Reoperation due to recurrence was performed in two patients. Among the factors predicting recurrence, multivariate analysis revealed that interventional radiological procedures and pathologic diagnosis were statistically significant. CONCLUSION: Laparoscopic resection of giant hepatic cysts is a simple and effective method to relieve symptoms with minimal surgical trauma. Moreover, the recurrence is dependent on the type of pathology involved, and the sclerotherapy undertaken.

OBJECTIVE: Obesity is considered a potential cause of several malignancies including endometrical cancer and breast cancer. We analyzed the relationship between obesity and cervical cancer to examine the role of obesity in developing cervical cancer and to prevent the cervical cancer. METHODS: A retrospective analysis was performed on 203 cervical carcinomas including 87 cervical adenocarcinoma and 116 cervical squamous cell carcinoma patients and as control group, 279 patients visiting severance hospital for PAP smear in the period 1994-2003. We analyzed medical records for patient characteristics and body mass index. The obtained data were analyzed using t-test, chi square test and logistic regression analysis by SPSS. RESULTS: There was no statistically significant risk factor in patient characteristics including body mass index between adenocarcinoma and control group. Between cervical squamous cell carcinoma and control group, patients age (odds ratio=0.952, p=0.06) and menopause status (odds ratio=2.420, p=0.02) were statistically significant risk factors. Body mass index was not significantly different among three groups (adenocarcinoma vs. control group, 23.0 +/- 3.4 vs. 22.4 +/- 3.2; squamous cell carcinoma vs. control group, 23.9 +/- 3.5 vs. 22.4 +/- 3.2). CONCLUSION: Our results were consistent with the concept that obesity was not a risk factor for cervical carcinoma. However menopause might be a potential risk factor in developing squamous cell carcinoma of the uterine cervix.
