OBJECTIVES: Apathy Evaluation Scale (AES) is one of the most frequently used scales to evaluate apathy. The purpose of this study was to evaluate the reliability and validity of the Korean version of the AES (K-AES) and to apply the K-AES in examining the characteristics of apathy in the Korean patients with schizophrenia. METHODS: 129 healthy people and 29 patients with schizophrenia have been evaluated using the K-AES, Physical Anhedonia Scale (PAS), Social Anhedonia Scale (SAS), and the Beck's Depression Inventory (BDI). Split-half reliability and internal consistency were evaluated and factor analysis and correlation analysis was conducted. Between-group comparison was conducted using independent sample t-tests. RESULTS: K-AES showed good reliability and validity. Factor analysis confirmed 3 factors, which represented interest and drive, initiative, self-awareness and self-assessment. Patients with schizophrenia showed significantly higher K-AES and BDI scores than the healthy group. K-AES scores in patients with schizophrenia were significantly correlated with the PAS score, but did not correlate with SAS and BDI scores. CONCLUSION: This study demonstrates the reliability and validity of the K-AES. Our findings also suggest that the K-AES may be a reliable instrument in assessing apathy as a negative symptom in patients with schizophrenia.

PURPOSE: There were many studies for adverse effects of carbon dioxide insufflation for laparoscopic cholecystectectomy, mainly focused on cardiovascular and respiratory system. The use of low pressure pneumoperitoneum has been shown to reduce adverse hemodynamic effects. However, its effect on tissue trauma & postoperative pain remains controversial. The aim of this study was to compare postoperative pain intensity between different insufflation pressures in laparoscopic cholecystecetomy. METHODS: We randomly allocated fifty four patients to 7 mmHg (LC7), 9 mmHg (LC9) and 12 mmHg (LC12) pneumoperitoneum group and examined operation time, postoperative pain intensity using visual analogue scale, amount of administered analgesics and complications prospectively. RESULTS: The characteristics of the patients were similar among groups. The procedure was successfully completed in all patients in the LC12 gruop, but in five patients of LC7 group and one patient of LC9 group the insufflation pressure was increased to 12 mmHg to complete the operation. There were no significant difference in postoperative pain scores, analgesic comsumptions among groups. There were difficulties to get a safe hemostasis and to create a adequate working space at acute cholecystitis in LC7 group. CONCLUSION: In our study, there was no superior advantage for postoperative pain when low pressure pneumoperitoneum was applied.

The Peutz-Jeghers syndrome is an autosomal dominant disease characterized by hamartomatous polyps in the gastrointestinal tract and mucocutaneous melanin pigmentation. Although these polyps are believed to have little potential for malignancy, and the disease was believed to have a relatively benign course, it recently has been recognized that patients with this syndrome are at increased risk for the development of cancer at gastrointestinal and nongastrointestinal sites. A 33-year-old male patient was admitted because of vomiting and abdominal pain for 3 months duration. A diagnosis of Peutz-Jeghers syndrome was made 3 years ago by multiple hamartomatous polyps confined to the colon and mucocutaneous pigmentation. A barium study showed abrupt string like luminal narrowing at the 4th portion of the duodenum. On laparotomy, there was an annular constricting mass involving the serosa of duodenum with multiple metastasis to liver, so a segmental resection of small bowel followed by chemotherapy was performed. The histologic finding was adenocarcinoma.

PURPOSE: Operative management of acute cholecystitis in aged patients has been shown to have relatively higher morbidity and mortality. The aim of this study was to determine appropriate management protocols for acute cholecystitis in those more than 70 years old. METHODS: From May 2003 to Dec 2009, we performed this study of patients over 70 years old that were diagnosed with acute cholecystitis (n=257). We excluded patients that had a hepatobilliary malignancy, a previous laparotomy history, secondary cholecystitis, or a high operative risk factor (n=78). Eligible participants were divided into two groups according to the first management of acute cholecystitis. One hundred two of the 179 (group A) had undergone a laparoscopic cholecystectomy (LC) or open cholecystectomy (OC) within 48 hr after arriving at the emergency room; 77 of the 179 (group 2) had PTGBD done as the first management protocol. We divided group 2 into group C (n=47) and D (n=30) according to cholecystectomy or not. We compared clinical outcomes of the two groups. RESULTS: The mean age of patients was 77.5 years old (102 for Group A and 77 for Group B. Univariant analysis of pre-operative clinical findings between groups A and B showed a significant difference only in age and in type of acute cholecystitis, However, the pre-operative co-morbidity of group B was significantly higher than that for group A. Comparing postoperative results between groups A and C, postoperative complications, open conversion rate, and mortality after cholecystectomy were not significantly different. CONCLUSION: PTGBD could be considered as appropriate management in aged patients with acute cholecystitis. Moreover, PTGBD can reduce unnecessary cholecytectomies.

A 21-year-old woman presented gastrointestinal manifestation showing intermittent abdominal pain, nausea, and vomiting. An upper endoscopic examination showed round, elevated mucosa at the antrum of the stomach anterior wall. After CT scanning, a huge degenerated gastrointestinal stromal tumor was suspected. Subtotal gastrectomy with Billroth II anastomosis was performed. Histologically, pseudocystic degeneration of the heterotopic pancreas was confirmed. The patient showed eventful postoperative course except temporary dilated gastric emptying. The patient is doing well without any abnormal symptom at 8-month follow-up. This report is a rare case of gastric outlet obstruction caused by a pseudocyst originating from a heterotopic pancreas in the gastric antrum.

PURPOSE: Pancretojejunostomy leakage is the most dreaded complication after a pancratoduodenectomy. However, little is known about what causes the leakage and how to prevent it. The aim of this study was to dentify the risk factors for pancreatic leakage. This paper describes our experience of its management. METHODS: Between Aug. 1996 and Aug. 2003, 75 consecutive patients with periampullary cancer or benign disease received a pancreatoduodenectomy. The patients' clinical characterisitcs, pathological features and surgical findings were retrospectively evaluated. The patients were classified into those with major complication and rhose with no complications and the risk factors were analyzed. Pancreatic leakage, intraabdomnial fluid collection and abscess, intraabdomnial bleeding were categorized as major complications related to a pancreatic fistula. RESULTS: The postoperative mortality and morbidity rate was 2.6% and 36%, respectively. Univariate analysis showed that the pancreatic texture, pathologic diagnoses and comorbidity were significant risk factors for major complications (P= 0.003, 0.045, 0.02). Multivariate analyses revealed that the, pancreatic texture was the only significant risk factor (P=0.003). The preoperative serum albumin level and pancreatic texture were significant risk factors for pancreatic leakage (p=0.03, 0.025) and multivariate analysis showed that the pancreatic texture was also the most significant risk factor. CONCLUSION: Considering that the pancreatic texture is the most significant risk factor for a pancreatic fistula, the technical skill and experience of the surgeon appears to be important for its prevention.

Colorectal polyps of mesenchymal origin are a rare group of colorectal disorders. A "mucosal Schwann-cell hamartoma," which is one type of polypoid lesion that originates from the mesenchyme, is a newly-proposed disease entity to be distinguished from the neurofibromas found in type-1 neurofibromatosis. This lesion is composed of pure Schwann-cell proliferation in the lamina propria and shows diffuse immunoreactivity for the S-100 protein. We report a case of a polypoid lesion of the colon with the features of this recently-proposed disease entity.

PURPOSE: Nonoperative management is currently considered a treatment modality in 50 to 80% of patients with blunt liver injury. Nevertheless 10 to 50% of patients need operative management, and the criteria for operative management have not established. The purpose of this study is to find criteria for operative management of patients with blunt liver injury. METHODS: The records of 117 patients who experienced blunt hepatic injury from January 1992 to April 1999 were reviewed retrospectively with respect to hemodynamic stability, transfusion requirement, injury severity score, liver injury grade, amount of blood in the peritoneal cavity, and pooling of contrast material on computerized tomography (CT). RESULTS: Among the 117 patients, 29 patients (25%) were treated operatively (Group 1) and 88 patients (75%) were treated nonoperatively (Group 2). The initial systolic blood pressure in Group 1 was significantly lower than that of Group 2 (74.4+/-30.3 mmHg vs 107.1+/-27.2 mmHg, p<0.001). The amounts of transfusion for hemodynamic stability were 2.1 units in Group 1 and 0.4 units in Group 2 (p<0.001). The injury Severity score of Group 1 was significantly higher than that of Group 2 (20.8 +/- 11.0 vs 10.7+/-6.8, p=0.03). The mean injury grade was 3.7+/-0.1 for Group 1 and 2.4+/-1.0 for Group 2, which was a statistically significant difference was seen (p<0.001). The amount of hemoperitoneum in Group 1 was significantly higher than that of Group 2 (p<0.001). The pooling of contrast material on CT was detected in 3 cases in Group 1. CONCLUSION: We can establish the following criteria for operative management: operative management is necessary for hemodynamic instability during resusci tation, positive peritoneal irritation signs, and presence of pooling of contrast material on CT. In cases above grade IV, above 500 mL of hemoperitoneum on CT, or above 2 units of blood transfusion during resuscitation, close observation in an intensive care unit is necessary. If abnormality develops during observation, prompt operative management is mandatory.

Coronary artery and valvular injuries after blunt chest trauma are an unusual condition. This diagnosis is very difficult to estabilish, but prompt diagnosis and proper management are important in life saving. We report one patient who develop left main coronary artery dissection, tricuspid insufficiency, mitral insufficiency and pericardial rupture following blunt chest trauma. One year ago, he had suffered a frontal impact in a traffic accident and recieved anti-tuberculosis medication for 10 months for chest discomfort. The correct diagnosis was confirmed noninvasively by transesophageal echocardiography and the patient was treated left main coronary artery dissection flap removal, mitral valve replacement, tricuspid valvuloplasty and repair of ruptured pericardium. The postoperative course was uneventful and the patient was fully recovered.

PURPOSE: The placement of a drainage tube in the common bile duct, following a choledochotomy, has become accepted as routine procedure since it was first reported, by Abbe, in 1892. However, many complications are associated with T-tube drainage, such as bile peritonitis after its removal, accidental dislodgement, bile leakage from the T-tube track and a high incidence of postoperative bacteremia, have been reported. This study was designed to evaluate the primary closure as a suitable surgical technique in placce of T-tube drainage following a choledochotomy METHODS: Between January and December 2002, primary closures were performed in 41 cases and T tube drainage in 112, following a choledochotomy. These cases were divided into 2 groups (group A: primary closure, and group B: T-tube drainage). The medical records of the patients were reviewed, and the following data analysed -age, sex, preoperative laboratory value, intraoperative finding, postoperative laboratory value, complication, and days of postoperative hospital stay. RESULTS: There were no significant differences observed in the data of the investigated parameters, with the exception of the mean post-operative hospital stay. The mean post- operative hospital stays were 11.82 and 18.08 days in groups A and B (P=0.0034), respectively. The complication rates of each group showed no statistical difference. However bile peritonitis or bile leakage after T-tube removal developed 5 cases from group B. There were 2 and 5 deaths due to MODS & ARDS, respectively. CONCLUSION: A primary closure, following a choledochotomy, may be a suitable alternative technique to T-tube drainage under reasonable conditions.
