A rehabilitation program with early mobilization and diet after laparoscopic colon surgery results in reduced recovery time without increased complications. These results suggest that a multimodal rehabilitation program may increase the short-term benefits after laparoscopic colon surgery.

TOET was feasible and could be performed safely for PTMC. TOET might become a new treatment option for the patients who do not want to leave visible scars on the body.

BACKGROUND: Upregulation of SLC2A genes that encode glucose transporter (GLUT) protein is associated with poor prognosis in many cancers. In colorectal cancer, studies reporting the association between overexpression of GLUT and poor clinical outcomes were flawed by small sample sizes or subjective interpretation of immunohistochemical staining. Here, we analyzed mRNA expressions in all 14 SLC2A genes and evaluated the association with prognosis in colorectal cancer using data from the Cancer Ge

Walnut has been known for its health benefits, including anti-cardiovascular disease and anti-oxidative properties. However, there is limited evidence elucidating its effects on cancer stem cells (CSCs) which represent a small subset of cancer cells that provide resistance against chemotherapy. This study aimed to evaluate the anti-CSCs potential of walnut phenolic extract (WPE) and its bioactive compounds, including (+)-catechin, chlorogenic acid, ellagic acid, and gallic acid. In the present s

Depth of mesorectal extension >5 mm is a significant prognostic factor in patients with T3 rectal cancer. Depth of mesorectal extension especially may be more important than the nodal status in predicting the oncologic outcome for patients who had received preoperative chemoradiotherapy.

Various factors were associated with postoperative clinical outcomes of patients with an intestinal perforation. Morbidity and mortality following an intestinal perforation were greater in patients with unstable initial vital signs, poor nutritional status, and feculent ascites.

Hypoxia-related gene (HRG) expression is associated with survival outcomes of colorectal cancer (CRC). Our aim was developing a nomogram predicting CRC overall survival (OS) with HRGs and clinicopathological factors. The Cancer Genome Atlas (TCGA) database was used as discovery cohort and two Gene Expression Omnibus databases (GSE39582 and GSE41258) served as validation cohorts. A genetic risk score model prognosticating OS was developed using mRNA expression level of HRGs. Nomogram predicting O

Germline mutations in the BRCA1 and BRCA2 genes are responsible for the predisposition and development of familial breast and/or ovarian cancer. Most mutations of BRCA1 and BRCA2 associated with breast and/or ovarian cancer result in truncated proteins. To investigate the presence of BRCA1 and BRCA2 germline mutations in Korean breast and/or ovarian cancer families, we screened a total of 27 cases from 21 families including two or more affected first- or second-degree relatives with breast and/o

BACKGROUND: This prospective study was performed to investigate whether postoperative ileus (POI) or early postoperative small bowel obstruction (EPSBO) affects the development of adhesive small bowel obstruction (SBO) in patients undergoing colectomy. METHODS: We prospectively enrolled 1,002 patients who underwent open colectomy by a single surgeon. POI was defined as the absence of bowel function for more than 5 days or as a delay in oral intake beyond 7 days postoperatively. EPSBO was defined

Purpose: This study was performed to evaluate the effects of age and sex on anorectal manometry. Methods: Seventy-four consecutive patients who underwent surgery for sigmoid colon cancer and who had neither anal disorders nor colonic obstruction were included in this study. There were 45 men and 29 women, and the mean age was 58.6. Pressure measurements used both the rapid and the station pull-through (RPT and SPT) methods, and volume measurements used a balloon-tipped catheter. Three pressure i

In this study, mesh repair showed low recurrence and a low complication rate with shorter hospital stay than relocation methods, though these differences were not statistically significant. Further studies, including randomized trials, are necessary if more reliable data on the surgical treatment of parastomal hernias are to be obtained.

Elderly patients with hyponatremia, combined resection, longer operation/anesthesia time and admission to ICU had tendencies to develop POD after major abdominal surgery. Surgeons should pay more attention to prevent POD, and a large-scale prospective study is needed to identify the risk factors of POD.

Purpose: Carcinoids are rare neuroendocrine tumors, mainly detected in the gastrointestinal tract. This study was performed to evaluate the incidence and necessity for additional treatment in incidental appendiceal carcinoids from patients presenting with symptoms of acute appendicitis. Methods: Of the patients; who underwent appendicectomies, with the diagnostic impression of acute appendicitis, from 1994 to 2003, six cases were diagnosed as appendiceal carcinoids. The medical records of these
