Anastomotic leakage (AL) is a well-known cause of morbidity after low anterior resection (LAR) for rectal cancer, but its impact on oncologic outcome is not well understood. The aim of this study is to investigate the impact of AL on long-term oncologic outcome and to identify factors associated with AL that may affect prognosis after LAR for rectal(More)
The prognostic nutritional index (PNI) has been reported to be a predictive marker for surgical outcomes and prognosis in gastrointestinal malignancies. In this study, we aimed to identify the impact of preoperative PNI on the recovery and long-term oncologic outcome of patients with colorectal cancer (CRC). A total of 3569 patients who underwent curative(More)
There has been little enthusiasm for performing robotic colectomy for colon cancer in recent years due to multiple factors, one being that the previous robotic systems such as the da Vinci Si® (dVSi) were poorly designed for multi-quadrant surgery. The new da Vinci Xi® (dVXi) system enables colectomy with central mesocolic excision to be performed easily in(More)
Alcohol is well-recognized systemic toxin that causes numerous adverse effects, including psychosocial problems, fatal myocardial infarction, stroke and atherosclerosis. The intra-abdominal complications caused by acute alcohol consumption have not been defined. We report an 80-year-old man with sub-acute small bowel and colonic ischemia after heavy alcohol(More)
The aim of this study is to investigate if retrieval of 12 lymph nodes (LNs) is sufficient to avoid stage migration as well as to evaluate the prognostic impact of insufficient LN retrieval in different treatment settings of rectal cancer, particularly in the case of preoperative chemoradiotherapy (pCRT).The data of all patients with biopsy proven rectal(More)
PURPOSE Adjuvant chemotherapy is routinely recommended for locally advanced colorectal cancer (CRC). There are very few data for the optimal starting date of adjuvant chemotherapy after the surgery. This study aimed to evaluate the effectiveness of earlier adoption of adjuvant chemotherapy after curative surgery for stage III CRC. METHODS In this study,(More)
PURPOSE Chest computed tomography is performed frequently for the preoperative pulmonary staging in colorectal cancers (CRCs) regardless of the result of chest x-ray (CXR) due to its high sensitivities and specificities. The advancement of CT technology detects more indeterminate lung lesions that may require further investigations, referrals and follow-up.(More)
Although transanal endoscopic surgery is practiced worldwide, there is no consensus on comparative outcomes between transanal endoscopic operation (TEO) and transanal excision (TAE). In this study, we reviewed our experiences with these techniques and compared patients who underwent TEO and TAE using propensity score matching (PSM). A total of 207 patients(More)
