OBJECTIVE Surgical resection has been the first choice of treatment for resectable pulmonary metastases from colorectal cancer. However, early intrapulmonary recurrence is often observed and appropriate assessment of prognostic factors is controversial. The aim of this study was to define the factors affecting survival and intrapulmonary recurrence after(More)
BACKGROUND Single-port laparoscopic surgery is a new technique that leaves no visible scar. This new technique has generated strong interest among surgeons worldwide. However, single-port laparoscopic colon surgery has not yet been standardized. Our aim in this study was to evaluate the feasibility of single-port laparoscopic colectomy compared with(More)
AIM Many studies support the role of carcinoembryonic antigen (CEA) as a strong indicator of the status of colorectal cancer patients, but evidence for carbohydrate antigen 19-9 (CA19-9) is poor. For this reason the study aimed to evaluate the prognostic value of preoperative serum CA19-9 levels in colorectal cancer patients. METHOD In all, 1190(More)
Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue tumors that arise from a peripheral nerve or exhibit nerve sheath differentiation. Most of these tumors arise on the trunk, extremities, or head and neck regions; they are very rarely located in the abdominal cavity. The patient was a 71-year-old man who was referred to our hospital for(More)
Surgical site infection (SSI) is a frequent complication of elective surgery for colorectal cancer. The classical clinical markers of infection—elevations in white blood cell count, C-reactive protein (CRP) level, and body temperature—do not precisely predict SSI after elective colorectal resection. The objective of this study was to evaluate the efficacy(More)
The caudal-related homeobox transcription factor CDX2 has a key role in intestinal development and differentiation. CDX2 heterozygous mutant mice develop colonic polyps, and loss of CDX2 expression is seen in a subset of colon carcinomas in humans. Ectopic CDX2 expression in the stomach of transgenic mice promotes intestinal metaplasia, and CDX2 expression(More)
The gastrointestinal tract is continuously exposed to a variety of chemicals and commensal bacteria. Recent studies have shown that changes in gut microbial populations caused by chlorine or other chemicals in the drinking water influence the development of human colorectal cancer, although the mechanism of tumorigenesis in the gut epithelium is obfuscated(More)
Laparoscopic assisted colectomy (LAC) is commonly performed, but LAC for transverse colon cancer is a complex procedure, even in the hands of experts. In particular, laparoscopic take-down of the splenic and/or the hepatic flexure and dissection of the lymph nodes around the middle colic vessels are extremely complicated maneuvers compared to the complexity(More)
Intra-abdominal high pressure and acidosis by carbon dioxide (CO2) pneumoperitoneum is known to affect various organ functions. In this study, changes in liver functions and liver histology were investigated during CO2 pneumoperitoneum in a large animal model. Fourteen white pigs were anesthetized with intubation and controlled ventilation. The pigs in the(More)
