BACKGROUND:In resent year,as the biological materials improving,all kinds of sutures are used widely in clinic. It is an important problem how to select the exact one for surgeon. OBJECTIVE:To compare the effect of antibacterial and poly (p-dioxanone) absorbable sutures (PDS) in abdominal wall incision. DESIGN,TIME AND SETTING:A contrast observation was performed at the Department of General Surgery,the Second Affiliated Hospital of Shantou University Medical College between January 2005 and August 2007. PARTICIPANTS:A total of 450 laparotomy patients,including 230 males and 220 females aging 18-78 years with the mean age of (40?9) years were collected in this study. METHODS:The 450 patients were randomly divided into three groups,including the antibacterial absorbable suture (AAS; abdominal wall incision except the skin was successively sutured with triclosan-coated antibacterial absorbable suture),PDS group (abdominal wall incision except the skin was successively sutured with PDS suture),and control group (abdominal wall incision was treated with common suture),with 150 cases in each group. All patients were followed up for 12-24 months. MAIN OUTCOME MEASURES:The visual analogue scale (VAS; point 0:indolence; point 10:severe pain),the incision heal classification and complications including incisional infection,rejection reaction,scar formation,incisional disruption and incisional hernia. RESULTS:A total of 450 cases were included in the final analysis. The VAS in the AAS group and the PDS group were significantly lower than control group (P

Objective To estimate the curative effect of non-gastrointestinal decompression in laproscopic colorectal surgery. Methods By using the single-blind-random test and prospective study, 55 patients were divided into two groups, experimental group and matched group. The difference of operating time, gastrointestinal function recovery time, adverse effect, complication, average length of hospital stay between two groups were observed and evaluated. Results The difference of operating time, gastrointestinal function recovery time, adverse effect, complication, average length of hospital stay between two groups were not statistically significant(P>0.05). The incidence rate of sore throat and cough and expectoration difficulty after operation was significantly lower in the experimental group (the rate was respectively 16.0% vs 77.7% and 8.0% vs 50.0, P<0.05). However, The incidence rate of nausea and vomiting, abdom-inal distension was not statistically significant(P>0.05). Conclusion In the perioperative period of laproscopic colorectal surgery, non-gastrointestinal decompression appears to be security and feasible.
