ABSTRACT
Objective To investigate the occurrence of postoperative healthcare-associated infection(HAI)in pa-tients with hepatobiliary malignant tumor,explore the related risk factors,so as to provide the basis for taking ef-fective prevention and control measures.Methods The occurrence of postoperative HAI in patients with hepatobili-ary malignant tumor in a hospital from January 2012 to December 2014 were retrospectively analyzed,risk factors for postoperative HAI were analyzed through reviewing and collecting patients’medical data.Results A total of 302 patients were investigated,42 (13.91 %)developed postoperative HAI,no multiple site infection occurred,the main infection site was deep surgical site (n=10,23.81 %),followed by lower respiratory tract (n=9,21 .43%) and digestive system (n=7,16.67%).Of 42 infection cases,38(90.48%)were sent specimens for pathogenic cul-ture,36 pathogenic strains were isolated,31 (86.11 %)of which were gram-negative bacteria,and 5 (13.89%) were gram-positive bacteria.Multivariate logistic analysis showed that operation duration≥2 hours (OR =1 .48), overweight (or obesity)(OR=1 .40),and preoperative radiotherapy (OR=2.98)were independent risk factors for postoperative HAI in patients with hepatobiliary malignant tumor (all P <0.05).Conclusion Incidence of postoper-ative HAI is high in patients with hepatobiliary malignant tumor,risk factors are long length of operation,over-weight (or obesity),and preoperative radiotherapy,effective prevention and control measures against risk factors should be taken.
ABSTRACT
Objective To evaluate the effectiveness and safety of percutaneous transhepatic balloon dilation for the removal of common bile duct stones.Methods 60 patients of common bile duct stone were divided into two groups:PTBD group (30 cases) and endoscopic sphicterotomy (EST) group (30 cases).Postoperatively biliary tract was drained for three days.Results All stones were removed in 28 patients (93％) in PTBD group and 29 cases (97％) in EST group.Early complications occurred in 13％ in PTBD patients and in 17％ in EST patients(x2 =0.35,x2 =0.13,P ＞0.05).There was no mortality in neither group.Long-term complications such as gallstone recurrence and cholangitis in PTBD group was significantly less than that in EST group (x2 =6.41,P ＜ 0.05).Conclusions The success rate of PTBD was similar to that of EST and while in PTBD the function of Oddi's sphincter was well reserved.PTBD procedure is a valuable alternative to EST in patients with bile duct stones,especially in patients who are not suitable for EST.
ABSTRACT
ObjectiveTo evaluate radio-frequency hemostasis in hepatectomy.MethodsFrom January 2009 to February 2011,the clinical data of 60 patients undergoing curative liver resection were divided into two groups using radio-frequency hemostasis (RFH) and clamp crushing method (CCM) respectively,RFH group (30 cases) and CCM group (30 cases).There was no difference between the 2 groups regarding the age,sex.hepatic function and tumor size.Data regarding the intra-operative and postoperative courses of the patients were analyzed.ResultsNo damage of hepatic vein occured in RFH group.Hepatic veins rupture occurred in 5 cases and massive bleeding occurred in 3 cases in CCM group.lntra-operative blood loss was significantly less in FRH group [ (219 ±62) ml] than in CCM group [ (416 ±96) ml ] (P ＜ 0.05 ).The postoperative drainage volume in RFH group was significantly less than that in CCM group on the third postoperative day.The serum ALT and T-BIL in RFH group was significantly lower than that in CCM group on postoperative day 1 and day 7 ( separately t =5.987,16.803,22.264,8.386,8.255,all P ＜0.05 ).Postoperative hepatic function in RFH group was significantly better than that in CCM group.ConclusionsThe use of radio-frequency hemostasis in hepatectomy is less traumatic,of less bleeding,faster recovery than clamp crashing method.
