As a new discipline, the cardiac surgery has a great development in the modern age, but still faces many problems and disputes. The emergence of the evidence-based medicine (EBM), which emphasizes the best evidence, and combines the doctor’s clinical experience to make the best judgment, gives the development of the cardiac surgery a new thinking. Four systematic reviews published in The Cochrane Library (Issue 3, 2004) have interprated the importance of EBM on how to resolve the actual problems in different field of the cardiac surgery.

ObjectiveTo evaluate the feasibility of clipless laparoscopic cholecystectomy (LC) to patients with calculous cholecystitis in acute inflammation stage. Methods The clinical data of 169 patients with calculous cholecystitis in acute inflammation stage who underwent clipless LC from December 2008 to July 2010 were analyzed. ResultsAll patients were successfully operated by LC except one case who suffered from gallbladder perforation and a conversion to open surgery was performed. The operation time ranged from 25-70 min (mean 38 min). The blood loss ranged from 10-200 ml (mean 22 ml). Peritoneal drainage was done in 38 patients, and the drainage time ranged from 1-6 d (mean 1.8 d). The time to out-of-bed activity was at 2 h after operation and the hospitalization time was 3-7 d (mean 3.5 d). There was no complication such as bile duct injury, hemorrhage, billiary leakage, and intra-abdominal infection. ConclusionWith improvement of operator’s experiences and skills, the clipless LC becomes feasible and safe for patients with calculous cholecystitis in acute inflammation stage.
The aim of this study was to evaluate ultrasonic findings as predictor of potential operative difficulties and complications during laparoscopic cholecystectomy (LC). From Auguest 1995 to December 1996 a total of 328 patients with symptomatic cholelithiasis (92 males, 236 females, mean age 45±17 years) were examined by ultrasonography (US) 1 to 3 days before LC. The US examination assessed six paramenters: (GB) volume of gallbladder thichness of GB wal position of neck of GB, stone mobility, maximal size of stone, and GB adhesions. On the basis of these US findings, a predictive judgment of technical difficulties was expressed as easy, difficult, and very difficult. Two hundred and twenty five patients presented with uncomplicated symptomatic cholelithiasis, and 103 had acute cholecystitis. The operation was predicted to be easy in 38% of cases, difficult in 48% and very difficult in 14% with a good correlation with the surgeon’s intraoperative judgment (Ｐ＜0.01). A significant association was found between stone mobility (Ｐ＜0.01), presence of adhesions (Ｐ＜0.01) and the difficulty of the procedure. Our results suggest that preoperative US is a useful screening test for patients undergoing LC, and it can help predict technical difficulties during LC.
ObjectiveTo explore the role of fast-track surgery (FTS) in day-case laparoscopic cholecystectomy (DLC) pain management. MethodsWe used bidirectional cohort study to investigate the patients undergoing day surgery of laparoscopic cholecystectomy admitted into our department. A total of 143 patients between April and September 2014 receiving routine pain management were chosen to be the control group, and 78 patients between October 2014 and January 2015 receiving FTS pain management were regarded as the FTS group. Postoperative pain, early ambulation, influence of pain on the sleep, patients' satisfaction and prolonged hospital stay rate were compared between the two groups. ResultsPain scores of patients in the FTS group 0-0.5, 0.5-6, 6-12, and 12-24 hours after surgery were significantly lower than those in the control group (P<0.05). The proportion of patients with early postoperative ambulation and patients' satisfaction rate in the FTS group were significantly higher than the control group (P<0.05). ConclusionThe FTS pain management model can effectively reduce patients' pain after DLC, accelerate patients' postoperative rehabilitation and increase patients' satisfaction.
ObjectiveTo evaluate the effect of different doses of dexmedetomidine on hemodynamics during endotracheal extubation of laparoscopic cholecystectomy in patients with hypertension. MethodsA total of 120 hypertension patients ready to undergo laparoscopic cholecystectomy under general anesthesia between December 2013 and December 2014 were chosen to be our study subjects. They were randomly divided into 4 groups with 30 patients in each:saline control group (group C), low-dose dexmedetomidine hydrochloride injection group (group D1), moderate-dose dexmedetomidine hydrochloride injection group (group D2), and high-dose dexmedetomidine hydrochloride injection group (group D3). The anesthesia methods and drugs were kept the same in each group, and 20 mL of saline, 0.25, 0.50, 1.00 μg/kg dexmedetomidine (diluted to 20 mL with saline) were given to group C, D1, D2, and D3 respectively 15 minutes before the end of surgery. Time of drug administration was set to 15 minutes. We observed and recorded each patient's mean arterial pressure (MAP) and heart rate (HR) in 5 particular moments:the time point before administration (T1), immediately after administration (T2), extubation after administration (T3), one minute after extubation (T4), and 5 minutes after extubation (T5). Surgery time, recovery time, extubation time and the number of adverse reactions were also detected. ResultsCompared at with, MAP and HR increased significantly at the times points of T3, T4, T5 compared with T1 and T2 in Group C and group D1 (P<0.05), while the correspondent difference was not statistically significant in group D2 and D3 (P>0.05). Compared with group C, MAP and HR decrease were not significantly at the time points of T3, T4, T5 in group D1 (P>0.05). However, MAP and HR decrease at times points of T3, T4, T5 in group D2 and D3 were significantly different from group C and D1 (P<0.05). After extubation, there were two cases of dysphoria in group C and two cases of somnolence in group D3, but there were no cases of dysphoria, nausea or shiver in group D1, D2, D3. ConclusionIntravenously injecting moderate dose of dexmedetomidine 15 minutes before the end of surgery can effectively reduce patients' cardiovascular stress response during laparoscopic cholecystectomy extubation for patients with hypertension, and we suggest a dose of 0.5 μg/kg of dexmedetomidine.

ObjectiveTo explore the causes of bile duct injury due to laparoscopic cholecystectomy (LC) and the preventive methods. MethodsA total of 18 patients with bile duct injury (with the occurrence rate of 0.4%) after LC between January 2003 and December 2012 were included. The patients included 5 males and 13 females with the age of 29-63 years old[averaging (42.3±3.6) years old]. The clinical data of the patients were retrospectively analyzed. ResultsIn the 18 cases of bile duct injury, 5 cases occur in emergency operation, 13 cases in selective operation. The operators were attending physician in 13 cases, and senior position in the other 5 cases. The reasons of the injury included misjudgment of the cystic duct in 9, duct aberrance in 3, excessive stretch of cystic duct in 2, 2 Mirizzi syndrome withⅠ-type surgical injury in 2, and right liver duct injury because of inappropriate stripping of gallbladder in 1. ConclusionThe operator's experience, severe conglutination and the bile duct aberrance are the chief causes. Preventive methods include strict system of operation accession, careful selection of candidates, timely laparotomy, and paying attention to the accumulation of operation experience and skills.
