Objective To evaluate the clinical effectiveness of laparoscopic and open appendectomy. Methods Literatures relating to randomized controlled trials in English and Chinese on the comparison of clinical effectiveness after laparoscopic and open appendectomy in appendicitis from PubMed，Wiley Online Library，Medline，Embase，Cochrane，CNKI，VIP，CBM databases were extracted，and methodological quality was evaluated by two reviewers independently with designed extraction form. The Cochrane Collaboration’s RevMan 4.2.2 software was used for data analysis. The wound infection，hospitalization time，operation time，hospitalization expenses，and peritoneal abscess were compared between laparoscopic and open appendectomy. Results Eight published reports of eligible studies were extracted. Compared with the open appendectomy， laparoscopic appendectomy had significant differences in lower wound infection rate 〔OR=0.19，95%CI （0.09，0.38），P＜0.000 01〕， longer operation time 〔WMD=3.66，95%CI （0.50，6.82），P=0.02〕，and more hospitalization expenses〔WMD=503.96，95%CI （337.23，670.70），P＜0.000 01〕.But there were no significant differences in hospitalization time〔WMD=-0.11，95%CI （-3.64，3.43），P=0.95〕 and incidence rate of peritoneal abscess 〔OR=1.40，95%CI （0.23，8.64），P=0.71〕 between laparoscopic and open appendectomy. Conclusions The wound infection rate is lower，but the operation time is longer，the hospitalization expenses is more in laparoscopic appendectomy as compared with open appendectomy. There are no statistically significant differences of hospitalization time and incidence rate of abdominal abscess between laparoscopic and open appendectomy.
Objective To evaluate the efficacy of multiple minimally invasive therapy and individualized treatments combination in severe acute pancreatitis. Methods The data of sixty-seven patients with severe acute pancreatitis between September 1998 and October 2008 undergoing multiple minimally invasive therapy and individualized treatments were analyzed retrospectively. The changes of APACHE Ⅱ score, CT score, WBC count, total bilirubin, AST, blood glucose, amylase, lypase, C-reactive protein, tumor necrosis factor-α, blood urea nitrogen, creatinine, and oxygenation index (PaO2/FiO2) were observed and compared between before and after treatment. Time of abdominal pain relieved, laparotomy rate, mortality rate, recovery rate, hospital stay, and cost of hospitalization were also observed. Results All the detected indexes improved significantly after treatments compared with those before treatments （Plt;0.001）. Time of abdominal pain relieved was (20.17±14.16) h. Laparotomy rate was 6.0% （4/67）. Mortality rate was 7.5% （5/67）. Recovery rate was 92.5% （62/67）. Hospital stay was (30.85±28.37) d and cost of hospitalization was (59 295.78±34 564.44) yuan. Conclusions Multiple minimally invasive therapy and individualized treatments for cases of severe acute pancreatitis with different causes, course, severity of disease, and complications, could significantly improve the clinical indexes and recovery rate of severe acute pancreatitis.
Objective To evaluate the efficacy and mechanism of early repeated intermittent veno-venous hemofiltration (RIVVH) in treatment of severe acute pancreatitis (SAP). Methods Sixty-five patients were randomly divided into RIVVH group (35 cases) and control group (30 cases). Symptoms, physical signs, serum concentration of BUN, Cr, AST, ALT, AMS were observed and compared between two groups. The changes of C-reactive protein (CRP) and result of bacteria culture, APACHEⅡ grades and Balthazar CT grades, open-belly surgery rate, complications, mortality rate, average hospital stay and costs were compared between these two groups. Results Two patients died of multiple organ failure in the RIVVH group, with 5.7% mortality rate, which was significantly lower than that in the control group (26.7%, 8/30), P＜0.05. Twenty-four hours after treatment, symptoms and signs were alleviated more in RIVVH group; blood biochemical indicator, oxygenation index and CRP level improved significantly in RIVVH group compared with those in control group （P＜0.05，P＜0.01）. Balthazar CT grades and APACHEⅡ grades decreased significantly after treatment in patients of RIVVH group （P=0.002, P＜0.001）. The hospital stay, costs, open-belly surgery rate, complications rate and infection rate were also significantly lower in RIVVH group comparing with those in control group （P＜0.05, P＜0.001）. Conclusion RIVVH can decrease the mortality rate of SAP with high recovery rate, less cost and shorter hospital stay.
ObjectiveTo evaluate the therapic efficacy for severe acute pancreatitis (SAP) during different periods. MethodsAccording to internalized standard, 234 patients with SAP admitted to this hospital from January 1986 to October 2009 were included, which were divided into two stages based on the time of admitting to this hospital. The first stage named prior operation group was from January 1986 to August 1998 (n=117), the second stage named individual treatment group was from September 1998 to October 2009 (n=117). There was comparability in demography and clinic between two groups. The prior operation group primarily underwent laparotomy and medication, and the individual treatment group underwent multiple combined therapies. These indexes were compared between two groups: hospital stay, cure rate, and mortality; the incidences of pancreatic pseudocyst, pancreatic and peripancreatic abscess, pancreatic encephalopathy, cardiac insufficiency, acute renal failure (ARF), acute respiratory distress syndrome (ARDS), and shock. The efficacies for early treatment, ascites, biliary pancreatitis, and pancreatic and peripancreatic complications were compared two groups by stratified analysis. ResultsCompared with the prior operation group, the hospital stay was shorter (Plt;0.05), cure rate was higher (Plt;0.001), and mortality was lower in the individual treatment group (Plt;0.001). During the treatments, the incidences of pancreatic pseudocyst, pancreatic and peripancreatic abscess, pancreatic encephalopathy, cardiac insufficiency, ARF, ARDS, and shock in the individual treatment group were lower than those in the prior operation group (Plt;0.05). According to the stratified analysis, the efficacies for early treatment, ascites, biliary pancreatitis, and pancreatic and peripancreatic complications in the individual treatment group were better than those in the prior operation group (Plt;0.001). ConclusionIn recent years, the change of therapeutic mode significantly improves the treatment efficacy for SAP.
