BACKGROUND: The prognosis following surgery for gastric cancer has been markedly improved as a result of early diagnosis and advancements both in operative techniques and perioperative management. However, gastrointestinal surgery in the presence of hepatic cirrhosis has shown high operative morbidity and mortality due to severe perioperative complications, such as bleeding, lymphorrhea, anastomosis leakage, hepatic failure, fluid retention, acute renal failure and multiple organ failure. Recently, the frequency of gastric cancer involving liver cirrhosis has been increasing, especially early gastric cancer cases. METHODS: From June 1995 to December 1997, a total of 410 patients with gastric cancer were treated surgically. Among them, 9 cases with liver cirrhosis underwent gastric resection. RESULTS: Three major postoperative complications occurred in 2 patient, anastomosis leakage in one, and bleeding in both. CONCLUSIONS: The purposes of this study were to assess the causes of complications and to decide the appropriate operation type for improving the prognosis for these patients with liver cirrhosis.

PURPOSE: This study aimed to compare the incidence and clinical significance of transient versus persistent acute kidney injury (AKI) on acute ST elevation myocardial infarction (STEMI). MATERIALS AND METHODS: The study was a retrospective cohort of 855 patients with STEMI. AKI was defined as an increase of > or =0.3 mg/dL in creatinine level at any point during hospital stay. The study population was classified into 5 groups: 1) patients without AKI; 2) patients with mild AKI that was resolved by discharge (creatinine change less than 0.5mg/dL compared with admission creatinine during hospital stay, transient mild AKI); 3) patients with mild AKI that did not resolve by discharge (persistent mild AKI); 4) patients with moderate/severe AKI that was resolved by discharge (creatinine change more than 0.5 mg/dL compared with admission creatinine, transient moderate/severe AKI); 5) patients with moderate/severe AKI that did not resolve by discharge (persistent moderate/severe AKI). We investigated 1-year all-cause mortality after hospital discharge for the primary outcome of the study. The relation between AKI and 1-year mortality after STEMI was analyzed. RESULTS: AKI occurred in 74 (8.7%) patients during hospital stay. Adjusted hazard ratio for mortality was 3.139 (95% CI 0.764 to 12.897, p=0.113) in patients with transient, mild AKI, and 8.885 (95% CI 2.710 to 29.128, p<0.001) in patients with transient, moderate/severe AKI compared to patients without AKI. Persistent moderate/severe AKI was also independent predictor of 1 year mortality (hazard ratio, 5.885; 95% CI 1.079 to 32.101, p=0.041). CONCLUSION: Transient and persistent moderate/severe AKI during acute myocardial infarction is strongly related to 1-year all cause mortality after STEMI.

BACKGROUND: The prognosis following surgery for gastric cancer has been markedly improved as a result of early diagnosis and advancements both in operative techniques and perioperative management. However, gastrointestinal surgery in the presence of hepatic cirrhosis has shown high operative morbidity and mortality due to severe perioperative complications, such as bleeding, lymphorrhea, anastomosis leakage, hepatic failure, fluid retention, acute renal failure, and multiple organ failure. Recently, the number of gastric-cancer patients patient who has liver cirrhosis has been increasing, especially for early gastric-cancer cases. METHODS: From June 1995 to December 1997, a total of 410 patients with gastric cancer were treated surgically in our degartment. RESULTS: Of the 410, 9 cases with liver cirrhosis underwent a gastric resection: 5 standard subtotal gastrectomies and 4 curative subtotal gastrectomies. Three major postoperative complications occurred in 2 patient: anastomosis leakage in one and bleeding in both. CONCLUSIONS: The purpose of this study was to report our complicated cases, to assess the causes of the complications, and to decide the appropriate operation type for improving the prognosis of these patients. Serosal flap can be the solving techniques in B-I anastomosis and complicated perforation in cirrhosis.

BACKGROUND/AIMS: A revised classification system for renal dysfunction in patients with cirrhosis was proposed by the Acute Dialysis Quality Initiative and the International Ascites Club Working Group in 2011. The aim of this study was to determine the prevalence of renal dysfunction according to the criteria in this proposal. METHODS: The medical records of cirrhotic patients who were admitted to Konkuk University Hospital between 2006 and 2010 were reviewed retrospectively. The data obtained at first admission were collected. Acute kidney injury (AKI) and chronic kidney disease (CKD) were defined using the proposed diagnostic criteria of kidney dysfunction in cirrhosis. RESULTS: Six hundred and forty-three patients were admitted, of whom 190 (29.5%), 273 (42.5%), and 180 (28.0%) were Child-Pugh class A, B, and C, respectively. Eighty-three patients (12.9%) were diagnosed with AKI, the most common cause for which was dehydration (30 patients). Three patients had hepatorenal syndrome type 1 and 26 patients had prerenal-type AKI caused by volume deficiency after variceal bleeding. In addition, 22 patients (3.4%) were diagnosed with CKD, 1 patient with hepatorenal syndrome type 2, and 3 patients (0.5%) with AKI on CKD. CONCLUSIONS: Both AKI and CKD are common among hospitalized cirrhotic patients, and often occur simultaneously (16.8%). The most common type of renal dysfunction was AKI (12.9%). Diagnosis of type 2 hepatorenal syndrome remains difficult. A prospective cohort study is warranted to evaluate the clinical course in cirrhotic patients with renal dysfunction.

PURPOSE: In surgical treatment for the elderly patients with the acute abdomen, the high morbidity and mortality rate become a serious problem because of the difficulty of the initial diagnosis. This study, therefore, aims at analyzing the clinical presentation of the elderly patients with the acute abdomen in order to reduce the high mortality rate for the elderly patients. METHODS: This study included 114 elderly patients who underwent the emergency operation due to the acute abdomen from May 2000 to May 2002. The age of the elderly patients was over 65 years old. The clinical characteristics of these patients were investigated retrospectively in this study. RESULTS: The most two common diseases were the acute appendicitis(25.4%) and the acute cholecystitis (21.9%) for the elderly patients. Then comes the intestinal obstruction, the gastrointestinal cancer, the colonic diverticulitis, and the gastrointestinal vascular disease in that order. The accuracy of the initial diagnosis was 79%, but the correlation between the accuracy and age significantly decreased as the age of the elderly patients increased. The postoperative complication rate was 26.3%, and the most common cause of the complications was the postoperative infection. The postoperative mortality rate was 11.4%, and the common causes of the death were the sepsis(61.5%), the postoperative bleeding, the acute renal failure, and the cardiovascular disease in order of frequency. It was found that there was a significant correlation between the complication rate and old age(p=0.021). In addition, there was a significant correla- tion between the mortality rate and old age p=0.012). CONCLUSION: In this study, it was found that the acute appendicitis and the cholecystitis were the common diseases for the elderly patients with the acute abdomen. The accuracy of the initial diagnosis was 79%; however, it decreased with the aging process. For aged people, that caused the increase of the complication and the mortality rate. It thus appears that elderly patients with the acute abdomen should be treated carefully and systematically.

BACKGROUND/AIMS: The present study aimed to determine the role of cystatin C as a prognostic factor for acute kidney injury and survival in cirrhotic patients. METHODS: The study investigated 53 liver cirrhosis patients. The renal function was evaluated by serum creatinine, serum and urine cystatin C, and 24-hour creatinine clearance on admission. Acute kidney injury was defined as a serum creatinine level exceeding the normal range (>1.2 mg/dl) and an increase of at least 50% from the baseline value. Multivariate analysis, receiver operating characteristic curve, and survival analysis were used to investigate prognostic factors for acute kidney injury and survival. RESULTS: Nine of the 53 cirrhotic patients (17.0%) developed acute kidney injury within 3 months. Both serum creatinine and cystatin C were predictive factors for acute kidney injury in univariate analysis, with a diagnostic accuracy of 0.735 (95% confidence interval (CI), 0.525-0.945; p=0.028) for serum cystatin C and 0.698 (95% CI, 0.495-0.901, p=0.063) for creatinine. In multivariate analysis, only serum cystatin C was an independent risk factor for acute kidney injury. The sensitivity and specificity of a serum cystatin C level of >1.23 mg/L to acute kidney injury were 66% and 86%, respectively. Serum cystatin C was positively correlated with the Model for End-Stage Liver Disease (MELD) and MELD-Na scores (r=0.346 and p=0.011, and r=0.427 and p=0.001, respectively). Comparison of the survival rates over the observation period revealed that a serum cystatin C level of >1.23 mg/L was a useful marker for short-term mortality (p<0.001). CONCLUSIONS: The accuracy in predicting acute kidney injury and short-term mortality was higher for a serum cystatin C level of >1.23 mg/L than for the serum creatinine concentration in patients with cirrhosis.

Background: Even though there were developments in various treatment techniques for acute limb ischemia, this disease is both life threatening and limb threatening. We investigated early and mid-term results of operation for acute limb ischemia with symptoms, the combined diseases, location of occlusion, complication in our patients. Meterial and Method: A retrospective review was conducted in 54 patients (43 men, 11 women, mean age 67.2 years) presenting with acute limb ischemia due to arterial thrombosis or embolism between Jan. 1996 and Dec. 2003, initially underwent thromboembolectomy. Result: In 33 patients (61.1%) the timeinterval from the onset of symptom to admission was within 24 hours. Causes of acute limb ischemia were embolic occlusion (27.8%), native arterial thrombosis (66.7%), and bypass graft thrombosis (5.6%). The distribution of arterial occlusion location was at 8 aortoiliac (14.8%) and 43 distal to femoral (79.6%) and brachial (5.6%). Clinical categories were grade I in 64.8%, IIa in 24.1%, IIb in 7.4%, and III in 3.7%. All the patients were received embolectomy. Underlying diseases were heart disease (72.2%), hypertension (33.3%), cerebrovascular accident (16.7%) and diabetes (18.5%). History of smoking was noted in 96.3% of the cases. Mortality rate was 5.6% and overall amputation rate was 9.3% (5/54). The 1-year limb salvage rate was 93.62%. Postoperative complications were 1 wound infection, 1 GI bleeding, 3 acute renal failure, and 1 compartment syndromes. The functional outcomes of the salvaged limb according to the recommended scale for gauging changes in clinical status, revised version in 1997 were +3 in 68.5%, +2 in 9.3%, +1 in 7.4%, -1 in 5.6%, -2 in 3.7%, and -3 in 5.6%. Conclusion: This study revealed 5.6% mortality and the amputation rate was 9.3%. We have retrospectively shown good results from early diagnosis & early operation. To improve outcome, early diagnosis and understand the underlying diseases, prompt treatment and operation would be appreciated.

Acute necrotizing pancreatitis often progresses into infection, sepsis, multiorgan failure and then, mortality and morbidity which are very high. From January 1988 to December 1996, 14 patients with surgically proved acute necrotizing pancreatitis at the Department of Surgery, Catholic University were analysed. 1) The patients consisted of 12 men and 2 women ranging in age from 27 to 74 years. 2) The ethiological factors included excessive alcohol abuse in 8 patients, biliary tract disease in 2 patients and unknown in 4 patients. 3) In clinical findings, the majority of the patients complained of sudden severe upper abdominal pain, nausea and vomiting, tachycardia, and abdominal distension. 4) Serum amylase level did not increase in 50% although the necrosis was severe, but aspartate transaminase increased in 13 cases. The lactic dehydrogenase and C-reactive protein increased in all tested cases. 5) In regards to diagnostic methods, computerized tomography was highly effective in getting early diagnosis and in finding the complications. 6) Early necrosectomy and drainage procedure was safe and effective. 7) Postoperative complications included pulmonary complications in 3 patients, pancreas fistula in 2, pancreas pseudocyst in 2, acute renal failure in 2, Diabetes mellitus in 2, gastrointestinal bleeding 1, and subphrenic abscess in 1 case. 8) Mortality rate was 36 %. In conclusion, computerized tomography may be used for early detection of acute necrotizing pancreatitis;. Aspartate transaminase, Lactate dehydrogenase and C-reactive protein may be good diagnostic and prognostic indicators upon admission. Necrosectomy and drainage should be chosen as the best surgical treatment in acute necrotizing pancreatitis patients.

BACKGROUND: Even though there were developments in various treatment techniques for acute arterial occlusion this disease still has high rate of mortalities and limb amputations. We investigated the combined diseases symptoms location of occlusion type of treatment complication and prognosis in our patients. MATERIAL AND METHODS: This study recruited 48 patients (42 men, 6 women, mean age 57.7 years) who received the operation from January 1995 toDecember 1998. We investigated the post-operation course via medical record review or telephone interview with patients or their family members. RESULT: The most common combined diseases were atherosclerosis in 30 patients. other diseases were 17 diabetes mellitus 16 hypertension and 12 atrial firillation. Pain and clod sensation were noticed in all patients paresthesia in 5 patients fibrillation. Pain and cold sensation were noticed in all patients paresthesia in 5 patients and lower extremity paralysis in 11 patients. In 29 patients the time interval from the onset of symptom to admission was over 72 hours and 15 patients were admitted within 24 hours. The distribution of arterial occlusion location was at 28 femoral arteries 14 popliteal arteries and 6 iliac arteries. All the patients were received embolectomy and 5 patients were received additional bypass grafting. Postoperative complications were 12 reocclusions. 6 compartment syndromes 6 skin necrosis and 2 acute renal failure. The mortality rate was 16.7% (8/48) and the amputation rate was 25%. CONCLUSION: This study revealed 25% reocclusion 25% limb amputation and 16.7% mortaliyt. To improve the prognosis of acute lower extrements arterial occlusion early diagnosis and understand the underlying diseases prompt treatment and operation additional operation including interventional radiologic examination and thorough postoperative care would be appreciated.
