Objective To explore the effects of bile from patients with cholecystolithiasis on the growth of human gallbladder carcinoma cells GBC-SD and the potential correlation between cholecystolithiasis and gallbladder carcinoma. Methods Cholecystolithiasis bile (CB) and normal bile (NB) specimens were used for this study. The proliferative effects of bile were measured by methabenzthiazuron (MTT) assay and cell cycle and apoptosis were analyzed by flow cytometry. Results CB can significantly promote the proliferation of GBC-SD cells, GBC-SD proliferative index increased significantly after treated with 1% CB for 48 h （P＜0.05）.The Sphase fraction of CB 〔（49.26±8.07）%〕 increased remarkably (P＜0.05) compared with that of NB 〔（25.54±6.57）%〕, and the CB percentage of G0/G1 phase 〔（40.59±9.12）%〕 decreased remarkably (P＜0.05) compared with NB 〔(60.64±13.42）〕%. Conclusion CB can promote the proliferation of human gallbladder carcinoma GBC-SD cells.
63 normal human gallbladders (non-stone group) and 47 inflammed cholesterol stone gallbladders(stone group) were assayed for the amount of macrophages(ΜΦ),the levels of tumor necro-sis factor (TNF) and interleukin 1(1L-1).It was found that in stone group,the amount of ΜΦ was significantly higher than in non-stone group(ΜΦ4101.90±295.72 vs 572.13±30.07AU,Plt;0.01).The levels of TNF and 1L-1 released mainly from the MΦ in stone group were also significantly increased in comparison with those in non-stone group(TNF 18.12±2.03 vs 4.45±0.39ng/mg,Plt;0.001;1L-1 102.42±7.84 vs 66.75±9.50u/mg protein,Plt;0.05).These results suggest that the activited ΜΦ and increases of TNF,1L-1 may be closely related to the inflammatory reaction in gallbladders and the formation of cholesterol gallstones.
Objective To study the clinical effects of laparoscope combined with choledochoscope in patients with cholecystolithiasis and choledocholithiasis. Methods Clinical data of 74 patients with cholecystolithiasis and choledocholithiasis between Mar. 2009 and Feb. 2011 in our hospital were retrospectively analyzed. Among them， 37 cases underwent the laparoscope combined with choledochoscope operation （referred to as the double mirror operation group） and 37 cases underwent the conventional open operation （open operation group）. The intraoperative conditions， therapeutic effect， and complications of patients in 2 groups were compared. Results The stone clearance rates of the two groups were 100%. The recurrence rate of 2 groups in the follow-up process was no significantly difference （P＞0.05）. In the double mirror operation group， the operative time was significantly longer than that open operation group （P＜0.01）；the intraoperative bleeding was significantly less than that open operation group （P＜0.01）；the anal exhaust time after operation， get out of bed time after operation， and total duration of hospitalization were significantly shorter than that open operation group （P＜0.01）；and the incidence of postoperative complications was significantly lower than that open oper-ation group（P＜0.01）. Conclusion Laparoscope combined with choledochoscope in treatment of cholecystolithiasis and choledocholithiasis patients has exact effects， with minor trauma， quicker recovery， and fewer complications， and it’s worthy of promotion.

【Abstract】ObjectiveTo investigate the effects of cholecystokinin （CCK） on diabetes mellitus with cholecystolithiasis. MethodsRelevant literatures of recent years were reviewed. ResultsCCK exists widely in human body．On the one hand, CCK enhances cholecystolithiasis by causing diabetes. On the other hand, its pathological changes can also lead to cholecystolithiasis. Besides, it is possibility that the CCKrelated gene abnormality is the common cause of diabetes and cholecystolithiasis. ConclusionCCK plays an important role in diabetes mellitus complicated with cholecystolithiasis. However, there is much yet to be known about CCK．
Objective To evaluate the clinical effectiveness of laparoscopic cholecystectomy and laparoscopic common bile duct exploration （LC＋LCBDE） and endoscopic retrograde cholangiopancreatography/endoscopic sphincterectomy with LC（ERCP/EST＋LC） in treatment for cholecystolithiasis with choledocholithiasis. Methods From January 2008 to July 2011， 127 patients suffered from cholecystolithiasis with choledocholithiasis underwent either LC＋LCBDE（85 cases， LC＋LCBDE group） or ERCP/EST＋LC（42 cases， ERCP/EST＋LC group） were collected retrospectively. The clearance rate of calculus， hospital stay， hospitalization expenses， and the rate of postoperative complications were compared between two groups. Results Eighty-five patients were performed successfully in the LC＋LCBDE group， out of which 54 patients had primary closure of common bile duct （LC＋LCBDE primary closure group）， whereas in 28 patients common bile ducts were closed over T tube （LC＋LCBDE＋T tube group）. Forty-two patients were performed successfully in the ERCP/EST＋LC group. There were no differences in the clearance rate of calculus〔100%（82/82） versus 97.37%（37/38）， P=0.317〕 and postoperative complications rate 〔（4.71% （4/85） versus 4.76%（2/42）， P=1.000〕 between the LC＋LCBDE group and ERCP/EST＋LC group. The median （quartile） hospital stay in the LC＋LCBDE group was shorter than that in the ERCP/EST＋LC group 〔12 （6） d versus 17（9） d， P＜0.001〕. In the LC＋LCBDE primary closure group， both median （quartile）?hospital stay and median（quartile） hospitalization expenses were less than those of ERCP/EST＋LC〔hospital stay：11（5） d versus 17（9） d， P＜0.001；hospitalization expenses：27 054（8 452） yuan versus 31 595（11 743） yuan， P=0.005〕 . Conclusions In the management of patients suffered from cholecystolithiasis with choledocholithiasis， both LC＋LCBDE and ERCP/EST＋LC are safe and effective. LC＋LCBDE， especially primary closure after LCBDE， is associated with significantly less costs as compared with ERCP/EST＋LC. Moreover， patients can be cured by LC＋LCBDE through one-stage treatment with the protection of the papilla function and no limits to the amount or size of the choledocholithiasis. The LC＋LCBDE is a preferable choice for the appropriate cases of cholecystolithiasis with choledocholithiasis.
Analysis of hospital cases of cholelithiasis in every four years of the recent 3 decades clearly shows the tendency of changes of cholelithiasis in clinical appearance in Chengdu.Constituent ratio of gallbladder stone was 12.56% in 70’s,47.54% in 80’s and 81.38% in 90’s.Bill duct stones including acute obstructive suppurative cholangitis was 71.01%, 46.08%,and 15.82% respectively. Biliary ascariasis was 11.67%, 2.75% and 0.68% respectively. Age incidence shows right moving, i.e. old patients increased. Urban patients increased.The influencing factors listed are: improvement of diagnostic methods; improvement of livelihood and diet; increased life expectancy; more health follow up examinations; technical improvements in rural areas and etc.
ObjectiveTo compare the effect of laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE) in the treatment of cholecystolithiasis combined with choledocholithiasis in elderly patients and non-elderly patients. MethodsThe clinical data of 185 cases of cholecystolithiasis combined with choledocholithiasis who treated in our hospital from September 2010 to November 2015 were analyzed retrospectively. Then the 185 cases of holecystolithiasis combined with choledocholithiasis were divided into elderly patients group (n=74) and the non-elderly patients group (n=111). The operative time, intraoperative blood loss, postoperative exhaust time, postoperative activity time, abdominal drainage time, postoperative hospital stay, total hospital stay, hospitalization cost, incidence of complications, unplanned analgesia, stone-free rate, rate of conversion to laparotomy, recurrence of stone, and mortality were compared between the two groups. Results① Intraoperative and postoperative indexes. No significant difference was noted in operative time and intraoperative blood loss (P > 0.050), but the postoperative exhaust time, postoperative activity time, abdominal drainage time, postoperative hospital stay, total hospital stay, hospitalization cost, and ratio of indwelling T tube of elderly patients group were all higher or longer than corresponding index of non-elderly patients group (P < 0.050). ② Postoperative complications and unplanned analgesia. There was no striking discrepancy in incidence of complications (including biliary leakage, peritonitis, haemorrhage, vomit, ectoralgia, and fever), and Clavien-Dindo grade (P > 0.050), except unplanned analgesia (P=0.007), the rate of unplanned analgesia in elderly patients group was higher than that of non-elderly patients group. ③Surgical effect. There was no significant difference in the stone-free rate, rate of conversion to laparotomy, and rate of recurrence of stone between the 2 groups (P > 0.050). ConclusionLC+LCBDE is also safe and effective in treatment of cholecystolithiasis combined with choledocholithiasis in elderly patients, it's worthy to be expanded and be used broadly.
Objective To evaluate the use of fast track surgery （FTS） in the treatment for cholecystolithiasis combined with calculus of common bile duct （CBD） by combination of laparoscope and duodenoscope. Methods One hundred and twenty patients with cholecystolithiasis combined with calculus of CBD underwent laparoscopic cholecyst-ectomy （LC） and endoscopic retrograde cholangiopancreatography （ERCP） were divided into FTS group （n=55） and conventional group （n=65），which were accepted the perioperative therapy of FTS or conventional therapy，respectively. After operation，the incision pain，nausea and vomiting，infusion time，loss of body weight，out-of-bed time，dieting time，postoperative hospitalization，hospital costs，and complications were compared in two groups. Results Compared with the conventional group，the postoperative infusion time，dieting time，out-of-bed time，and postoperative hospitali-zation were shorter，the incidence rates of pulmonary infection，and urinary systems infection，pancreatitis，nausea and vomiting， and incision pain were lower，the loss of body weight was lower in the FTS group （P＜0.05），but the differences of WBC and serum amylase at 24 h after operation were not significant between the FTS group and conventional group（P＞0.05）. Conclusion The FTS is safe，economic，and effective in the treatment for cholecystolithiasis combined with calculus of CBD by combination of laparoscope and duodenoscope.
ObjectiveTo investigate the feasibility, safety, cost, and patient satisfaction of ambulatory laparo-scopic cholecystectomy(ALC). MethodsThe clinical data of patients who divided into ALC group(678 cases) and in-patient laparoscopic cholecystectomy(IPLC) group(1 534 cases) in our hospital from April 2011 to December 2012 were retrospectively analyzed. The operative time, conversion rate, complication rate, hospitalization time, cost of hospi-talization, rehospitalization rate, and patient satisfaction were analyzed and evaluated. ResultsThere were no significant differences of the operative time, postoperative complication rate, and rehospitalization rate between the 2 groups(P > 0.05). The conversion rate(0.44%), and hospitalization time[(1.2±0.5)d] of the ALC group were significantly lower or shorter than those of IPLC group[3.19%, (4.8±1.3) d], P < 0.05. The direct, indirect health care costs, and the total costs of the ALC group were (6 555.6±738.7), (230.0±48.0), and (8 856.0±636.0) yuan, respec-tively; and lower than those of the IPLC group[(7 863.71, 014.6), (973.0±136.5), and(8 856.0±636.0)yuan], P < 0.05. ConclusionALC is safe and feasible, and could shorten the hospitalization time, lower the medical cost, speed up the bed turnover, and increase the efficiency in the use of health resource.
