Metastasis of hepatocellular carcinoma (HCC) to the ovary is notably rare. We present a case of HCC metastasis to the ovary with a review of the literature, which includes only 7 reported cases. A 43-year-old hepatitis B virus carrier was admitted with a right ovarian cystic mass. She had been diagnosed with HCC 2 years prior, for which she underwent transarterial chemoembolization followed by right posterior sectionectomy. Eight months after the hepatectomy, the first intrahepatic recurrence was detected and treated with transarterial chemoembolization. An additional intrahepatic recurrence occurred 12 months after transarterial chemoembolization and was managed with left medial sectionectomy and intra-operative radiofrequency ablation. Over the following 3 months, the patient developed elevated alpha-fetoprotein, and positron emission tomography showed a cystic mass in the right side of the pelvic cavity with focal hypermetabolic activity, which suggested a site of recurrent HCC. An exploratory laparotomy was performed, and a soft, ovoid cystic mass was identified in the right ovary. There was no evidence of metastases in the liver, left ovary, or peritoneum. Because of the absence of tumor on the surface of the ovary and the lack of peritoneal seeding, the mode of metastasis was thought to be hematogenous. Therefore, a right salphingo-oophorectomy was performed. The pathological features showed metastatic HCC with clear resection margins. Although metastasis of HCC to the ovary is very rare, it should be suspected in a female patient with a lower abdominal mass and an elevated serum AFP level in the absence of other demonstrable metastases.

Biliary obstructions are rarely caused by a foreign body and have received sparse attention. We present an unusual case with pruritis and abdominal pain caused by impacted full length surgical gauze within the common bile duct. The patient had previously undergone an open cholecystectomy. Radiological investigations were inconclusive and suggestive of either a calculus or a cholangiocarcinoma. Surgical exploration revealed full length surgical gauze within the common bile duct. Because imaging modalities are often non-determinant, the possibility of biliary tract obstruction from a foreign body should be borne in mind for patients with unusual presentations, especially those who have previously undergone surgery.

We report two cases of adrenal abscesses that occurred following a Histoacryl(R) (N-butyl-2-cyanocrylate) injection for variceal bleeding. Patients had been diagnosed with alcoholic liver cirrhosis and gastric varices bleeding and received a Histoacryl(R) injection for the variceal bleeding. Patients had fever and abdominal tenderness and were diagnosed with an adrenal abscess at 2 months following the Histoacryl(R) injection. One patient received open drainage and the other underwent percutaneous drainage. When a patient has previously been injected with Histoacryl(R) for the treatment of variceal bleeding and presents with fever, an evaluation for an unusual complication such as adrenal abscess is recommended.

Invasive gastric Candida infection in patient with co-morbidity can cause stenotic change if it is developed at anatomically narrowing portion, such as distal antrum, pylorus, or duodenal bulb. However, proper management of benign stenosis by diffuse gastric Candidasis is still under controversy and palliative bypass surgery has several shortcomings because high risk operative group may be included in this case. Palliative placement of self-expandable metallic stent has been settled as a standard management of malignant gastric pyloric obstruction and it is expected to be applied in benign stenotic lesions due to its gradual dilation effect. We described a case of stenosis by diffuse gastric Candidasis at anastomosis of subtotal gastrectomy, which was managed by temporary placement of self-expandable metallic stent.

Massive rectal bleeding from the appendix, considered a rare case of lower gastrointestinal bleeding, is not easily recognized by various diagnostic modalities. A multidisciplinary approach for both a diagnosis and a differential diagnosis is important because the identification of the bleeding site is crucial to proceed to a proper intervention and there are various causes of appendiceal bleeding. Because early colonoscopy plays an important role in the diagnosis and management of lower gastrointestinal hemorrhage, we report a case of a life threatening massive rectal bleeding from the appendix diagnosed by colonoscopy. We also present a review of the literature.

BACKGROUND/AIMS: The aim of this study was to investigate the primary management experience for giant liver hemangiomas greater than 20 cm in size. METHODS: Records of patients referred for evaluation of radiologically and/or histopathologically proven giant liver hemangiomas between January 2007 and March 2010 were retrospectively analyzed. The reasons for referral, results of imaging studies, preoperative and surgical treatments, and outcome were reviewed. RESULTS: A retrospective analysis was performed for 14 patients diagnosed with a giant hemangioma on the basis of an imaging study and/or a histopathological examination. All cases were diagnosed as giant liver hemangioma with at least one lesion greater than 20 cm in size. Abdominal discomfort was the main presenting complaint for the referral in 9 patients (64.2%). Abdominal ultrasound established the diagnosis in 12 patients (85.7%). Twelve patients underwent liver resection, 2 of whom underwent staged resection. Enucleation was performed in 2 patients. Selective transcatheter arterial embolization was implemented in 9 patients. Postoperative morbidity occurred in 3 patients (21.4%). No complications related to the hemangiomas occurred during follow up. CONCLUSIONS: Liver resection is indicated for giant liver hemangiomas with abdominal discomfort, especially for lesions greater than 20 cm in size. Staged operations are performed for patients with multiple lesions. Preoperative selective transcatheter arterial embolization alleviates progressive abdominal pain.

BACKGROUND/AIMS: Pyogenic liver abscess (PLA) is a serious, life threatening condition with a high mortality rate that represents a diagnostic and therapeutic challenge. The aim of this study was to collect demographic data and clinical, laboratory and microbiological characteristics of PLA patients treated between 2000 and 2010. We also aimed to collect information regarding our management experience of these cases. METHODS: As a retrospective review, 47 patients with PLA in a tertiary referral center were examined to determine their demographic characteristics, clinical features, and laboratory, imaging, and microbiologic findings as well as the treatment outcome. RESULTS: Cryptogenic PLA was the most frequently identified type of PLA, while benign biliary tract disease was the most frequently identifiable cause of PLA (18/47 patients; 38.3%). Leukocytosis and elevated alanine transaminase were common laboratory findings and were observed in 35 (74.5%) and 22 (46.8%) patients, respectively. Increased fibrinogen was also detected in 11 of 15 investigated cases (73.3%). Notably, infection-induced thrombocytopenia occurred in 8 patients (17%). Diabetes mellitus was associated with the occurrence of infection induced shock when compared to the non-diabetic group (p<0.05). Patients with two or more comorbid diseases had longer hospitalizations when compared to patients with one comorbid disease or those without comorbidities (p<0.001). The number of days needed to establish diagnosis was correlated with the length of hospitalization (p<0.001). The overall hospital mortality rate was 2.1% (1/47). CONCLUSIONS: Characteristics of PLA patients from the past 10 years are presented. The number of days needed to establish a PLA diagnosis was correlated with the length of the hospital stay. The hospital stay of PLA patients can be further improved by early diagnosis and effective treatments during the early stages of PLA progression.

BACKGROUND/AIMS: The aim of this study was to evaluate the seroconversion rate of a hepatitis A virus (HAV) vaccination in patients with hepatitis B virus (HBV)-related chronic liver disease (CLD). METHODS: Analyses were conducted using clinical records from 94 patients with chronic HBV infection who were seronegative for IgG anti-HAV antibodies between September 2008 and June 2009. Two doses of an HAV vaccine were administered 24 weeks apart. A third vaccine dose was administered only for patients seronegative for anti-HAV antibodies at week 48. RESULTS: The seroconversion rate of anti-HAV following the two-dose vaccination was 86.17%. The seroconversion rate of anti-HAV was not significantly different according to age or status of liver disease. The rate was higher in female than in male patients. A third HAV vaccine dose was administered to 13 patients seronegative for anti-HAV after the two-dose regimen, and 84.62% of these patients showed seroconversion at week 72. CONCLUSIONS: HAV vaccination is effective in most Korean patients with HBV-related CLD, and it might be necessary to evaluate three-dose vaccination approach for non-responders to the conventional regimen to maximize the success of an HAV vaccination program.

BACKGROUND/AIMS: To investigate serological patterns of hepatitis B based on electrochemiluminescent immunoassays and the distribution characteristics of these patterns in hospitalized children and adolescents in Zhejiang, China between 2006 and 2010. METHODS: Five serological markers, including hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), antibody to hepatitis B surface antigen (anti-HBs), antibody to hepatitis B e antigen (anti-HBe), and antibody to hepatitis B c antigen (anti-HBc), were chosen as a routine panel to monitor hepatitis B virus (HBV) infection and vaccination efficacy. A total of 33,187 children (21,187 boys and 12,000 girls) were selected using the following exclusion criteria: a previous diagnosis of hepatitis, age >16 years or an address outside of Zhejiang. RESULTS: The average HBV vaccination coverage rates among 20,766 boys and 11,782 girls were 98.62% and 98.68%, respectively. Seventeen serological patterns of hepatitis B were found, and the dominant pattern was 'anti-HBs (+) alone' (62.03%) followed by 'negative pattern' (23.46%). The rates of the other 15 patterns ranged from 8.14% to 0.003%. Of 236 HBsAg-positive patients, the overall rate of seropositivity was 0.71%. The anti-HBs levels were grouped into 3 ranges (10-100 mIU/mL, 100-1,000 mIU/mL, and >1,000 mIU/mL) for all anti-HBs-positive children (36.08%, 43.43%, and 20.49%, respectively). CONCLUSIONS: A low HBsAg carrier rate and a relatively high anti-HBs positive rate are present in hospitalized children and adolescents in Zhejiang. The distribution of serological patterns is associated with age but is mostly independent of gender.
