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. After extraction of the intestine via minilaparotomy,(More)
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. Decompression with a long intestinal tube failed to resolve the obstruction. Thus, surgery was performed.(More)
Cholesterol 7alpha-hydroxylase (cholesterol-NADPH oxidoreductase, EC, 7alpha-hydroxylating) is known to have extremely sensitive sulfhydryl group(s). It is believed that a cysteine residue that has a sulfhydryl group plays an important role in the decrease of this enzyme activity. The amino acid sequences of cholesterol 7alpha-hydroxylase of five(More)
A 43-year-old woman who complained of abdominal fullness, appetite loss, and constipation was diagnosed as unresectable advanced schirrhous gastric cancer with left supra-clavicular lymph node metastases, massive ascites, rectal stenosis, and bilateral hydronephrosis due to peritoneal metastases. The biopsy specimen showed a poorly differentiated(More)
Mitochondrial sterol 27-hydroxylase (EC is an important enzyme, not only in the formation of bile acids from cholesterol intermediates in the liver but also in the removal of cholesterol by side chain hydroxylation in extrahepatic tissues. The enzyme has been assayed by complicated methods using radiolabeled substrates or deuterium-labeled(More)
BACKGROUND/AIMS Abdominoperineal resection (APR) is generally performed in the lithotomy position (LT-APR). The aim of this retrospective study was to evaluate the advantage of the right lateral (RL) position during the perineal phase of APR, in extended APR (ext-APR) that needed additional excision of the pelvic organs and sacrococcyx, and in total pelvic(More)
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(More)
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(More)
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)(More)
BACKGROUND/AIMS Although the size and number of the metastatic liver tumors have been considered to be prognostic factors after hepatectomy in patients with colorectal liver metastases, the importance of these parameters is still controversial. The aim of this study was to evaluate the importance of the new factor, namely, the sum of longest diameters of(More)
