BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) has been known to greatly influence the survival rate of patients with liver cirrhosis. However, the factors that affect the survival rate in patients with SBP need to be clarified. METHODS: This study enrolled 95 liver cirrhosis patients diagnosed with SBP. The laboratory findings of their serum and ascitic fluid were examined and the characteristics of the isolated microorganisms in their peritoneal fluid were analyzed. RESULTS: The proportion of patients with culture-positive SBP was 41.1%, and 47 microorganisms were isolated from the ascitic fluid. The proportions of cultured bacteria that were Gram negative and Gram positive were 57.4% and 40.4%, respectively. The proportions of Escherichia coli, Klebsiella species, and Streptococcus species were 25.5%, 19.1%, and 19.1%, respectively. Enterococcus species represented 12.8% of the microorganisms cultured. The overall survival rates at 6, 12, and 24 months were 44.5%, 37.4%, and 32.2%, respectively. There was no relationship between the bacterial factors and the survival rate in SBP. Multivariate analysis revealed that the presence of hepatocellular carcinoma (HCC; P=0.001), higher serum bilirubin levels (> or =3 mg/dL, P=0.002), a prolonged serum prothrombin time (i.e., international normalized ratio >2.3, P<0.001), renal dysfunction (creatinine >1.3 mg/dL, P<0.001), and lower glucose levels in the ascitic fluid (<50 mg/dL, P<0.001) were independent predictive factors of overall survival rate. CONCLUSIONS: HCC, higher serum bilirubin levels, a prolonged serum prothrombin time, renal dysfunction, and lower ascitic glucose levels are associated with higher mortality rates in cirrhotic patients with SBP.

BACKGROUND/AIMS: Intestinal tuberculosis (ITB) evades early diagnosis due to non-specific clinical manifestations and difficulties in confirming the disease process. In the current study, we determined the diagnostic appearance and clinical manifestations of ITB in recent 10 years according to diagnostic guidelines, as proposed by the IBD Study Group of Korean Association for the Study of the Intestinal Diseases (KASID). METHODS: Fifty-six patients with ITB who were diagnosed at Seoul Paik Hospital between January 2001 and August 2010 were retrospectively reviewed. The diagnosis of ITB was defined as definite or probable in accordance with the diagnostic guidelines and the clinical features were analyzed in comparison with previous studies involving ITB in Korea. RESULTS: The mean age at the time of diagnosis was 45+/-15 years (range, 17-71 years). Definite and probable diagnoses were obtained in 29% and 71% of the patients, respectively. Twenty-three percent of the patients had synchronous active pulmonary TB and 14% of the patients had other forms of abdominal TB, such as TB mesenteric lymphadenitis or peritonitis. The most common symptoms were abdominal pain (43%), followed by diarrhea (30%), weight loss (14%). Twenty-seven percent of the patients (15 cases) were asymptomatic and diagnosed on comprehensive health care or post-operative surveillance. Only 2 patients (3.6%) underwent surgery for complications, such as intestinal obstruction and perforation. CONCLUSIONS: ITB is still prevalent in Korea; however, in the recent 10 years the symptoms of ITB have been milder than previously reported. In addition, the complication rates of ITB were remarkably decreased, suggesting that early diagnosis of ITB was increased.

BACKGROUND/AIMS: Mini-probe endoscopic ultrasonography (mEUS) is a useful diagnostic tool for accurate assessment of tumor invasion. The aim of this study was to estimate the accuracy of mEUS in patients with early colorectal cancer (ECC). METHODS: Ninety lesions of ECC underwent mEUS for pre-treatment staging. We divided the lesions into either the mucosal group or the submucosal group according to the mEUS findings. The histological results of the specimens were compared with the mEUS findings. RESULTS: The overall accuracy for assessing the depth of tumor invasion (T stage) was 84.4% (76/90). The accuracy of mEUS was significantly lower for submucosal lesions compared to mucosal lesions (p=0.003) and it was lower for large tumors (> or =2 cm) (p=0.034). The odds ratios of large tumors and submucosal tumors affecting the accuracy of T staging were 3.46 (95% confidence interval [CI], 1.05 to 11.39) and 6.25 (95% CI, 1.85 to 25.14), respectively. When submucosal tumors were combined with large size, the odds ratio was 14.67 (95% CI, 1.46 to 146.96). CONCLUSIONS: The overall accuracy of T stage determination with mEUS was considerably high in patients with ECC; however, the accuracy decreased when tumor size was >2 cm or the tumor had invaded the submucosal layer.

This is a case report of simultaneous primary leiomyosarcomas in the spine and liver. A 64-year-old woman presented to the Seoul Paik Hospital with epigastric discomfort and constipation that she had experienced for two months. A physical examination revealed severe tenderness around the thoraco-lumbar junction. Esophagogastroduodenoscopy showed an ulceroinfiltrative lesion on the gastric angle. An abdominopelvic CT scan revealed two low attenuated lesions in the S4 and S8 regions of the liver, as well as a soft tissue mass at the T10 vertebra. Percutaneous ultrasonography-guided needle biopsy of the hepatic nodules revealed a leiomyosarcoma. The tumor at the T10 vertebra was removed to avoid spinal cord compression. The histology of this tumor was compatible with that of leiomyosarcoma. The potential primary sites for leiomyosarcoma, including the lung, thyroid, breast, kidney, genitourinary organs, and gastrointestinal tract, were subsequently investigated. No detectable abnormal findings that would suggest the origin of the tumor were found. Synchronous primary leiomyosarcomas in the spine and liver are quite rare and have a poor prognosis.
