ABSTRACT
Objective To explore the efficacy and safety of combined intravenous and intrathecal vancomycin in treatment of patients with intracranial infection after craniotomy. Methods Clinical data of a total of 60 consecutive patients with intracranial infections after cranial operation admitted to Department of Neurosurgery of Nanfang Hospital of Southern Medical University from June 1st 2013 to June 1st 2015 were retrospectively analyzed. The patients were divided into two groups: intravenous injection only (n = 25) and combined intravenous and intrathecal injection (n = 35). In both groups of patients intravenously given vancomycin hydrochloride 500 kU every 6 hours as well as third or fourth generation of cephalosporins or meropenem. In combined intravenous and intrathecal injection group, in addition to 20 mg vancomycin was slowly injected via lumbar puncture after release of cerebrospinal fluid (CSF) once a day. The clinical efficacy and complications of the two groups were compared. Results The recovery rate in the combined intravenous and intrathecal injection group was significantly higher than that in the intravenous injection only group (94.3% vs. 76.0%, χ2 = 4.220, P = 0.040). Lowering of white blood cell count in combined intravenous and intrathecal injection group was significantly earlier than that of the intravenous injection only group (time to become normal: 8 days vs. 13 days). The time of recovery in combined intravenous and intrathecal injection group was significantly shorter than that of the intravenous injection only group (days: 9.9±0.7 vs. 13.4±1.1, t = -2.716, P = 0.009). There were 3 patients who experienced nerve root irritation symptoms in combined intravenous and intrathecal injection group. Symptomatic treatment was given and injection speed was slowed down for these patients. There were no severe complications, such as coma, epilepsy or death in both groups. Conclusion Combined intravenous and intrathecal injection of vancomycin could be a safe and effective therapy for intracranial infection after craniotomy.
ABSTRACT
Objective To summarize our experience in the prevention and treatment of right accessory hepatic duct and right hepatic duct injury during laparoscopic cholecystectomy. Methods The clinical data of 21 cases with right accessory hepatic duct or right hepatic duct during laparoscopic cholecystectomy were reviewed retrospectively. Result According to anatomy identified by preoperative work-up and selective cholangiography during the operation, 18 cases had the right accessory hepatic duct,eleven of them were confirmed intraoperatively. The accessory hepatic ducts were conserved in 3 cases and clipped without biliary leaks postoperativly in 7 cases; One case had biliary leaks postoperatively with the duct sutured intraoperatively, and recovered well conservative therapy. Accessory hepatic ducts were accidentally injuried in 7 cases, two patients were transferred to open surgery; three cases were confirmed to be injuried and clipped by second laparoscopic exploration because of biliary leaks postoperatively. Three cases had a low confluence of the right and left hepatic duct with the gallbladder duct joining the right bile duct, the ducts were conserved in 2 cases and injuried in one. Postoperatively all these 21 cases were followed up for 2 years, without jaundice or liver dysfunction. Conclusions To prevent injury of right accessory hepatic duct and right hepatic duct. High vigilance and familiarity with the anatomic variants of the biliary tree and intraoperative cholangiography in selective cases are fundmental.
ABSTRACT
Objective To determine the expression of E-cadherin-catenins complex(E-cad,?-cat,?-cat and ?-cat) in early gastric cancer and their relationships with biological characteristics of early gastric cancer by evaluating the invasion and the lymph nodes metastasis of eraly gastric cancer(ECG).Methods 53 cases of EGC,who accepted radical operations from January 1997 to December 2000 in Sir Run Show Hospital were included in this study.According to the invasion depth and lymph nodes metastasis,they were divided into different sub-groups for discussion.Also the normal gastric mucosa of 10 cases with extra-gastric disease were selected as control group.Results All four proteins(E-cad,?-cat,?-cat and ?-cat) were normally expressed in control group.In early gastric cancer,the abnormal expression rates of E-cad,?-cat,?-cat and ?-cat were 64.2%,69.8%,66% and 73.6%,respectively.In the sub-group of mucosal invasion,the abnormal expression rates were 61%(14/23),65.2%(15/23),47.8%(11/23) and 56.5%(13/23),respectively.But in the sub-group of submucosal invasion,the abnormal expression rates were 66.7%(20/30),73.3(22/30)%,80%(24/30) and 86.7%(26/30),respectively.In sub-group of no lymph node metastasis,the abnormal expression rates were 61.4%(27/44),65.9%(29/44),63.6%(28/44) and 70%(31/44) respectively.In sub-group of lymph node metastasis,the abnormal expression rates were 77.8%(7/9),88.9%(8/9),77.8%(7/9) and 88.9%(8/9) respectively.Abnormal expression of ?-cat and ?-cat had significantly difference between the sub-group of mucosal invasion and the submucosal invasion(P
