Prognostic Factors Associated with Preoperative Clinicophysiological Outcomes of Distal Cholangiocarcinoma.

Background/aims: Although biliary tract cancer is generally associated with a high mortality rate, patients with distal cholangiocarcinoma have better prognoses, compared to those with periampullary cancer. This study aimed to determine the preoperative clinicophysiological factors predictive of survival and recurrence in patients with distal cholangiocarcinoma.

Methods: Forty-five patients (34 men) with distal cholangiocarcinoma who underwent pancreaticoduodenectomy between 2005 and 2013 were examined retrospectively at our center and associated hospitals.

Heterotopic Ossification in Rectal Carcinoma: Report of a Case and Review of the Literature.

Heterotopic ossification in colorectal carcinoma is extremely rare. This report presents the case of a 57-year-old male who had undergone a low anterior resection following a diagnosis of rectal carcinoma. Histological examination showed heterotopic ossification in the tumor.

The Clinical Outcomes after Total Pancreatectomy.

Background: Total pancreatectomy (TP) is not more beneficial than less aggressive resection techniques for the treatment of pancreatic neoplasms and is associated with high morbidity and mortality. However, with advances in surgical techniques and glycemic monitoring, and the development of synthetic insulin and pancreatic enzymes for postoperative treatment, TP has been increasingly indicated. This is a review of the recent literature reporting the clinical outcomes after TP.

Synchronous ovarian metastasis from colorectal cancer: A report of two cases.

Ovarian metastasis of colorectal cancer is relatively rare. The present study reports two cases of synchronous ovarian metastasis from colorectal cancer, which were managed by cytoreductive surgery. In case one, a 60-year-old female patient presented with a multilocular pelvic tumor and ascites.

Emergency surgery for hemorrhagic shock caused by a gastrointestinal stromal tumor of the ileum: A case report.

In this report, a case of hemorrhagic shock caused by a gastrointestinal stromal tumor (GIST) of the ileum, which was successfully treated by emergency surgery, is presented. A 67-year-old male patient presented to the Ibaraki Medical Center, Tokyo Medical University (Ami, Japan) in July 18, 2014, with dizziness and blood in the stool. Upper endoscopy and colonoscopy failed to reveal the source of the hemorrhage, although abdominal contrast-enhanced computed tomography revealed extravasation of the contrast medium into the small intestine.

Improved surgical outcomes for hilar cholangiocarcinoma: changes in surgical procedures and related outcomes based on 40 years of experience at a single institution.

Purpose: This study aimed to examine the changes in procedures for hilar cholangiocarcinoma (HC) surgery and patient survival following HC surgery over a 40-year period.

Methods: Between 1974 and 2014, 239 consecutive patients underwent surgery for HC. The changes in perioperative therapy and short- and long-term surgical outcomes were evaluated.

Surgical approaches to advanced gallbladder cancer : a 40-year single-institution study of prognostic factors and resectability.

Purpose: The aim was to evaluate prognostic factors and factors associated with the resectability of advanced gallbladder cancer (GBC).

Methods: This was a single-institution retrospective review of 274 consecutive surgically-treated cases of advanced GBC (excluding incidental GBC and early GBC). Univariate and multivariate analysis were performed to assess prognostic variables.

Type C chronic hepatitis with the discovery of a small hepatocellular carcinoma 7 years after successful interferon therapy.

The patient, a 61-year-old man, had sustained injuries in a traffic accident at the age of 26, for which he received a blood transfusion. Since 1988 (age, 49 years), abnormal hepatic function had been detected, and, because of the presence of hepatitis C virus antibodies, he was diagnosed as having type C chronic hepatitis. Based on a liver biopsy that was conducted in July 1992 (age, 53), a histological diagnosis of chronic active hepatitis (F(1)/A(2)) was made.
