Clinicopathological features, postoperative survival and prognostic variables for cancer-related survival in patients with mucinous colorectal carcinoma.

Purpose: To investigate the clinicopathological features and postoperative survival of patients with mucinous colorectal carcinoma (MC) and to identify the factors related to long-term survival.

Methods: Twenty-three patients who had undergone resection for MC at Miyazaki University Hospital from 1991 to 2006 were followed up for at least 5 years or until death. The effects of the clinicopathological variables on the 5-year cancer-specific survival were assessed by the univariate analyses.

Clinical features and prognostic factors of bone metastases from colorectal cancer.

Purpose: To investigate the clinical features and prognoses of patients with diagnosed bone metastases from colorectal cancer (CRC).

Methods: This was a 16-year retrospective study of 32 patients with bone metastases secondary to CRC, who were seen at National Kokura Hospital between 1993 and 2008. The influence of clinical and pathologic variables on survival was assessed by univariate and multivariate analyses.

Medical students' attitudes to laparoscopic surgery.

Background/aims: The purpose of the present study was to evaluate the attitude of medical students to laparosocopic surgery.

Methodology: Two hundred and seven medical students completed a questionnaire regarding their visualization of, understanding of, and interest in observation of laparoscopic surgery via laparoscopic monitor (laparoscopic observation) and of open surgery, either directly (open direct observation), or via video monitor observation (open monitor observation). They were also asked about their willingness to become an operator (operator).

Video monitoring and slide and video presentations as tools for surgical education.

Background/aims: To provide medical students with good visualization and understanding of surgical procedures, we used video monitoring (Monitor) in the operating room and slide (Slide) and video (Video) presentation in the conferences. The purpose of this study was to evaluate the effect of these visual aids on surgical education.

Methodology: One hundred and twenty-nine fifth- and sixth-year medical students completed a questionnaire regarding their visualization of, understanding of, and interest in all surgical procedures observed and procedures pertaining to their assigned patients.

Factors influencing outcome after surgery for stage IV colorectal cancer.

Purpose: According to the classification system of the Japanese Society for Cancer of the Colon and Rectum, Stage IV colorectal cancer is characterized by distant metastasis, which is defined by four factors: liver metastasis (H factor), metastasis to organs other than the liver (M factor), peritoneal dissemination (P factor), and distant lymph node metastasis (N factor). We conducted this study to investigate the postsurgical prognosis of patients with Stage IV colorectal cancer (CRC), in reference to each of these four factors.

Methods: We analyzed the medical records of 73 patients who underwent surgery for Stage IV CRC at our hospital between 1991 and 2001.

Circular tumor growth: a prognostic factor in stage II colorectal carcinoma.

Background/aims: Almost all patients with stage II colorectal cancer are spared adjuvant chemotherapy, yet a considerable number of these patients die from the disease. The aim of this retrospective study was to identify factors negatively affecting survival of patients with stage II colorectal cancer treated by curative resection.

Methodology: Study subjects were 88 patients who had undergone curative resection for stage II colorectal cancers at Miyazaki University Hospital during the period from 1987-1999.

Multiseptate gallbladder: report of a case.

A 53-year-old Japanese female was referred to Miyazaki University hospital for the surgical treatment of gastric cancer. She had no symptoms and the presence of the complex cystic gallbladder with multiple and linear hyperechogenic septa was incidentally found by ultrasonography. Multicystic lesion of gallbladder was also observed on DIC-CT and MRCP.

Intraoperative enteroscopy in minimally invasive surgery.

Purpose: The purpose of this study was to assess the efficacy and safety of intraoperative enteroscopy (IOE) in patients undergoing minimally invasive surgery.

Methods: Twelve patients underwent minimally invasive surgery and IOE at Miyazaki University Hospital. Patients included 11 men and 1 woman.

Internal herniation through the mesenteric opening after laparoscopy-assisted right colectomy: report of a case.

We discuss a rare complication in a patient who underwent laparoscopic colectomy. A 69-year-old woman underwent laparoscopy-assisted right colectomy for cancer of the ascending colon. Two months after the operation, bowel obstruction developed.
