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)
Although about 50% of lung cancers have distant metastasis at the time of initial diagnosis, colonic metastases are extremely rare. This report presents a rare clinical case of colonic metastasis from primary squamous cell carcinoma of the lung. A 60-year-old female with anorexia and fatigue was referred to the department of pulmonary surgery in our(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)
High body mass index (BMI) is a risk factor for colorectal cancer. However, the prognostic impact of BMI and other factors may differ between elderly and younger colorectal cancer patients. We analyze here prognostic factors in the surgical management of octogenarians with colorectal cancer and clarify the prognostic impact of BMI. Cox regression analysis(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)
Few studies have investigated the risk factors in patients with peritoneal carcinomatosis (PC) from colorectal cancer (CRC) who die within 3 months of undergoing surgical intervention and systemic chemotherapy. This study aimed to identify the risk factors associated with the post-treatment 3-month mortality rate. Retrospectively collected data from(More)
BACKGROUND Postoperative adhesion formation is regulated by peritoneal fibrinolysis, which is determined by tissue-type plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1). This study compared peritoneal fibrinolysis and adhesion formation after laparoscopic surgery (LAP) and open surgery (OP). METHODS We divided 154 male rats into 3(More)
The aim of the present study was to determine selection criteria for patients with stage IV colorectal cancer (CRC) who were likely to show survival benefits of metastasectomy. Clinicopathological data of 119 patients with stage IV CRC who underwent primary CRC resection were retrospectively reviewed. The prognostic factors were analyzed according to the(More)
Hypoxia inducible factor-1α (HIF-1α) is a major regulator of tumorigenesis in hypoxic conditions and therefore represents a potential therapeutic target in colorectal cancer (CRC). Clinical significance of HIF-1α expression in liver metastases has not been elucidated. Therefore, this study aimed to clarify the clinical significance of HIF-1α expression in(More)
