BACKGROUND: We constructed a prospective study to evaluate the outcome of patients referred to an intensivist for ICU admission as well as the factors associated with ICU admission refusal. METHODS: Patients referred for ICU admission to medico-surgical ICU in our hospital for 16 weeks were included in this study. We classified the reasons for refusal into three categories: inappropriate referral; triage; futility. Also we classified admitted patients into two categories: immediate admission; delayed admission. After initial evaluation of a patient by an intensivist, we checked the patient's outcome for following 28 days. RESULTS: 632 patients had been referred for ICU admission during study period. Among them, 445 (70%) patients were admitted and 187 (30%) patients were refused ICU admission. 116 patients were refused because of inappropriate referral, 52 for triage and 19 for futility. 394 patients were admitted immediately and 51 were refused initially but were later admitted. When 116 inappropriate referral patients were excluded, the mortality rates for immediate admission, delayed admission and triage/futility were 14.4%, 39.2% and 56.3%, respectively (P<0.05). Standardized mortality ratio was 0.70 for immediate admission, 1.20 for delayed admission, 1.28 for triage and 1.30 for futility (P<0.05). The factors associated with refusal for ICU admission were age, medical division, diagnostic group and high Mortality Probability Model II0 (MPM II0) grades. CONCLUSIONS: Because the triage decision for ICU admission influences the patients' outcome, an intensivist must carefully come to a decision when admitting patients to ICU by considering the appropriate guidelines for ICU admission and triage.

Surgeons are often faced with the problem of bowel obstruction in a patient who has previously undergone operation for malignant disease. Mechanical obstruction secondary to recurrent carcinoma is associated with poor survival. Surgical attempts to relieve malignant obstruction have significant morbidity and mortality rates and limited success in resolving symptoms. Then there is a temptation to assume that the obstruction is due to advanced malignancy and that death is inevitable. But a benign, correctable cause of obstruction will be found in about 25% of these patients. For this study, we had selected 63 cases of small bowel obstruction in patients with a previous operation for cancer which were admitted at Korea University Hospital between 1990 to 1995. The 43 men and 20 women had a mean age of 55.5 years. Forty one cases(65%) had obstruction due to recurrent carcinoma. The location of primary malignancies were as follows: 47 of the patients(74.6%) had adenocarcinoma of the stomach, 16 patients(25.4%) had adenocarcinoma of the colorectum. The median interval from the original operation for the malignancies until the development of bowel obstruction was 17.5 months. In our study, the small bowel obstruction due to recurrent carcinoma was frequently predicted when ascites and pleural effusion were present. We concluded that patients with no known recurrence or a short interval to the development of mechanical obstruction should be aggressively treated with surgery and for patients with known abdominal recurrence in whom nonoperative therapy fail, the surgical palliation are inevitable.

Background: The long-term outcomes of patients discharged from the hospital after successful care in intensive care unit (ICU) are not briskly evaluated in Korea. The aim of this study was to assess long-term mortality of patients treated in the ICU and discharged alive from the hospital and to identify predictive factors of mortality. Methods: In 3,679 adult patients discharged alive from the hospital after ICU care between 2006 and 2011, the 1-year mortality rate (primary outcome measure) was investigated. Various factors were entered into multivariate analysis to identify independent factors of 1-year mortality, including sex, age, severity of illness (APACHE II score), mechanical ventilation, malignancy, readmission, type of admission (emergency, elective surgery, and medical), and diagnostic category (trauma and non-trauma). Results: The 1-year mortality rate was 13.4%. Risk factors that were associated with 1-year mortality included age (hazard ratio: 1.03 [95% CI, 1.02–1.04], P < 0.001), APACHE II score (1.03 [1.01–1.04], P < 0.001), mechanical ventilation (1.96 [1.60–2.41], P < 0.001), malignancy (2.31 [1.82–2.94], P < 0.001), readmission (1.65 [1.31–2.07], P < 0.001), emergency surgery (1.66 [1.18–2.34], P = 0.003), ICU admission due to medical causes (4.66 [3.68–5.91], P < 0.001), and non-traumatic diagnostic category (6.04 [1.50–24.38], P = 0.012). Conclusions The 1-year mortality rate was 13.4%. Old age, high APACHE II score, mechanical ventilation, malignancy, readmission, emergency surgery, ICU admission due to medical causes, and non-traumatic diagnostic category except metabolic/endocrinologic category were associated with 1-year mortality.

BACKGROUND: Adequate nutrition support reduces infectious complications, mortality and length of hospitalizationin intensive care unit. However, there are multi factors like frequent null per os (NPO) due to examination, intolerance to tube feeding, complication of TPN (total parenteral nutrition) and ineffective recognition by medical staff. The purpose of this study is to identify detrimental effects of cumulative energy deficiency in critically ill patients. METHODS: The patients who were received tube feeding or total parenteral nutrition for more than 5 days were investigated. Daily and cumulative energy deficiency was tabulated until oral intake was achieved or until they discharged or died. Patients were divided into two groups, severe energy deficient group (>10, 000 kcal) or mild energy deficient group (<5, 000 kcal). Then we compared clinical outcomes between two groups. RESULTS: Total 150 patients were studied. 48 (32%) patients were severe energy deficient group and 42 (28%) patients were mild energy deficient group. Mortality and nosocomial infection were significantly higher in severe energy deficient group than in mild group. Hospital day and ICU day were significantly higher in severe energy deficient group than in mild group. CONCLUSIONS: Severe energy deficiency was very common in critically ill patients and it deteriorated the clinical outcomes such as mortality, nosocomial infection, hospital day and ICU day.

Primary gastric squamous cell carcinoma represents a rare entity. Up to date, only seven cases have been reported in Korea. This paper reports a case of a 51-year-old male patient whose stomach cancer was diagnosed during general routine check-up. Upper gastrointestinal endoscopy showed a large ulcero-fungating mass on the body of the stomach. Histological examination of biopsy confirmed squamous cell carcinoma. An extended total gastrectomy including splenectomy and segmental resection of the large bowel was conducted. Postoperative adjuvant chemotherapy with capecitabine and oxaliplatin was followed. The patient has been following up the out patient's clinic after discharge.

BACKGROUND: Significant aortic stenosis of various underlying etiologies presents with similar clinical characteristics and is usually treated with aortic valve replacement. We performed a clinical study to evaluate the clinical characteristics, changes of echocardiographic parameters before and after aortic valve replacement in adult aortic stenosis patients. METHODS: From January 1991 through December 1995, 159 patients underwent aortic valve replacement at Sejong General Hospital. Sixty-two cases(39%) of those patients were pure or predominant aortic stenosis. We observed the clinical characteristics, etiology, operative procedure, perioperative complication and mortality, And we observed the changes of echocardiographic parameters such as mean and peak pressure gradients at aortic valve, ejection fraction, systolic and diastolic left ventricular internal dimensions, left ventricular wall thickness, left ventricular mass index retospectively at preoperative and postoperative periods regularly within 1 month, 1 yr, 3 yrs after operation(mean follow up period : 16 months, 1-36 months). RESULTS: 1) The age of patients ranged from 31 to 71 years(mean 55+/-11), and 60%(37 cases) of them were men. 2) Regarding underlying heart disease, the most common etiology of aortic stenosis was rheumatic valvular heart disease(32 cases, 52%), followed by congenital bicuspid aortic valve(16 cases, 25%) and degenerative change(14 cases,23%). 3) 44 cases(77%) of the patients had dyspnea,12 cases(19%) had chest pain, and 5 cases(8%) had history of syncope at the time of operation. Asymptomatic patient was only 1 case. 4) Seven patients(11%) had associated coronary artery disease, and only 1 case(about 2%) underwent concomitant coronary bypass surgery. 5) Post-operative complications which developed within 1 month were bleedings(8 cases, 13%), arrhythmias(7 cases, 11%) and infections(4 cases, 6%). After 1 month, bleedings related with anticoagulation were most common(7 cases, 11%). Other complications were hemolytic anemia(1 case), and aortic dissection(1 case). There was one surgery related mortality(2%) which happened during operatin due to myocardial ischemia. 6) The size of implanted prosthetic valves ranged from 19 to 25mm(mean 22+/-2mm). Larger valves(23-25mm) showed lower peak(p=0.839) and mean pressure gradients(p=0.019) than smaller valves(19-21mm). 7) We observed that peak and mean pressure gradient, left ventricular internal dimension, and left ventricular mass index had decreased significantly after aortic valve replacement. 8) The average preoperative functional class(2.3) had improved significantly at 1 month after surgery(1.2), and 1 year after surgery(1.0). CONCLUSIONS: In our series, the most common etiology of aortic stenosis was rheumatic valvular disease(52%). The incidence of combined coronary artery disease was 11%, lower than other reports. And only 1 case(2%) underwent concomitant coronary artey bypass graft surgery. The average size of implanted valves was 22mm, and the larger size had lower transaortic peak and mean pressure gradients after operation. The most common perioperative complication was bleeding and mortality rate was about 2%. Echocardiography was useful for evaluation of postoperative changes, such as transaortic peak and mean pressure gradient, left ventricular internal dimension and left ventricular mass index.

We report the case of a 57-year-old woman with abdominal discomfort. The patient had anemia and hypoalbuminemia. Esophagogastroduodenoscopy and colonoscopy revealed diffuse infiltrative lesions at the stomach, duodenum, and ascending colon. Multiple biopsies were taken and histological examination of the biopsies from the stomach, duodenum and colon showed amyloid deposits stained positively with Congo red. Immunohistochemistry study showed positive sign of kappa and lambda chain at light chain stain. In addition, monoclonal components at serum electrophoresis confirmed the diagnosis of amyloid light-chain amyloidosis. The patient was treated with thalidomide and dexamethasone.

Recently, placement of self-expandable metallic stents has been used for the treatment of colorectal obstruction. As domestic awareness of colorectal cancer has increased, the number of colorectal stenting procedures performed has also increased. We aimed to provide evidence-based recommendations for colorectal stenting to aid gastroenterologists in making informed decisions regarding the management of patients who present with colorectal obstruction. The working group consisted of eight gastroenterologists who actively practice and conduct research in the field of colorectal stenting and are the members of the Stent Study Group of the Korean Society of Gastrointestinal Endoscopy. A literature search was conducted using the PubMed, Embase, KoreaMed, and the Cochrane Library databases to identify relevant articles published between January 2001 and June 2012. Based on the modified Delphi process, 10 recommendation statements regarding indications, usefulness, methodology and complications of colorectal stenting, and alternative treatments for malignant colorectal obstruction were determined. The contents will be widely distributed, and periodically revised to reflect the latest knowledge. These evidence-based recommendations for colorectal stenting will provide gastroenterologists and patients with appropriate and balanced information, and will improve the quality of care.

PURPOSE: Recent studies have indicated that the p53 tumor suppressor gene and vascular endothelial growth factor (VEGF) play an important role in the angiogenic process of tumors. In this study, the correlation of the expressions of p53 and VEGF and the clinical features in gastric cancer were investigated. METHODS: The expressions of p53 and VEGF in gastric cancer were determined using immunohistochemistry on 98 randomly selected gastric cancer patients that had received curative resection. RESULTS: The expression of p53 and VEGF were observed in 51% and 50% of tumors, respectively. A significant correlation was found between p53 expression and the tumor histological type (P=0.045). The higher the TNM stage, the higher the observed level of p53 expression. The p53 and VEGF expression stati coincided in 70.4% of tumors, with a significant correlation found between the p53 and VEGF stati. Significantly worse survival rates were found in p53-positive and VEGF-positive patients than in those that were p53-negative and VEGF-negative. CONCLUSION: The present results indicated that p53 and VEGF expressions are useful in predicting the prognosis of patients with gastric cancer.
