bjective To study the change of mucins of expression in lithic cholecystitis and cholecystic adenomatiod polyps. MethodsMUC1 and MUC3 were detected in the mucosa of human normal gallbladders (20 cases, control group), of calcareous cholecystitis (38 cases, calcareous group) and of adenomatoid polyps (18 cases, polyp group) with immunohistochemical stains and Western blotting methods. ResultsThe positive rate and optical density values of MUC1 were increased significantly in calcareous and polyp group vs control group (P＜0.01), otherwise, MUC3 was decreased markedly (P＜0.01). Conclusion The expressions of MUC1, MUC3 were not synchronization in different lesions of cholecyst.
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.
To study bacterial changes of bile, to detect relationship between formation of core of gallstones and bacterial infection. Floras of bacteria in bile were studied in patients with gallstones by using aerobic, anaerobic and Lforms (X, Y,L) culturing system.Results: Bacterial growth positive was found in 88 of 98 patients in which single bacterial growth accounted for 54 cases, multiple growth 34 including type X 83, type L 23 and type Y 5. The results show that some alteration of bacteria flora exists during biliary infection and S. Liguefaoiens and E. Coli are the most frequent bacteria present. Formation of the core of gallstone might be related with bacterial infection.
ObjectiveTo investigate and compare the advantages and disadvantages of laparoscopic cholecystolithotomy and laparoscopic cholecystectomy for patients with gallbladder stone. MethodsThe eligible patients with gallbladder stones hospitalized in our department between January 2007 and December 2011 were included, and all of them received either laparoscopic cholecystolithotomy (observation group) or laparoscopic cholecystectomy (control group) minimally-invasive surgery. The operation time, bleeding volume, enterokinesia recovery time, hospital stay, post-operative complication and follow-up results were compared between the two groups. ResultsA total of 148 patients were included, with 68 patients in the observation group and 80 patients in the control group. In this cohort, the success rate of surgery for the observation group and the control group was 100.0% (68/68) and 98.8% (79/80), respectively; and the success rate of complete stone removal was 100% for both two groups. B-ultrasound examination after 2 weeks of treatment showed that gallbladder wall was normal and gallbladder contraction rate was more than 30% for all patients with laparoscopic cholecystolithotomy. The operation time was (49.6±5.2) minutes for the observation group and (50.5±6.2) minutes for the control group, and bleeding volume was (9.5±1.4) mL for the observation group and (50.2±8.1) mL for the control group; the difference in bleeding volume was significant between the two groups (P<0.05). The difference in enterokinesia recovery time[(33.9±2.2) and (34.4±2.6) minutes] or hospital stay[(3.4±1.0) and (3.6±1.2) days] between the observation group and the control group was not significant (both P >0.05). The post-operative complications of bleeding, bile leakage and wound infection were not observed in both two groups, and all patients were followed up for 6 to 12 months with no stone recurrence; and only 2.7% of patients (1/37) had stone recurrence after 3-year follow-up. ConclusionBoth laparoscopic cholecystolithotomy and laparoscopic cholecystectomy procedures are safe and efficient. However, laparoscopic cholecystolithotomy not only reserves gallbladder but also has superiority of less bleeding volume.
Objective To investigate the method of the treatment on cholecystolithiasis combined with calculus of common bile duct (CBD) by laparoscopy with combination of choledochoscope and duodenoscope and its significances. Methods Forty-two patients with cholecystolithiasis combined with calculus of CBD were treated by laparoscopy with combination of choledochoscope and duodenoscope from Jan. 2007 to Dec. 2008 in this hospital. Under general anesthesia, laparoscopic cholecystectomy was performed first, then the anterior wall of CBD was opened, calculus of CBD was treated by choledochoscope and duodenoscope intraoperatively. Then primary suture of the CBD was performed under laparoscope and nasobiliary drainage duct was placed. Results One case was converted to laparotomy, 41 cases succeeded and left hospital after being taken off the nasobiliary drainage duct in 5-7 d. No case died, no bile leakage, no bleeding or perforation of upper digestive tract, and no acute pancreatitis happened after operation. Conclusion Laparoscopy with combination of choledochoscope and duodenoscope treating cholecystolithiasis combined with calculus of CBD is a safe, effective and quickly recovering method with less sufferings and trauma.
This study was designed to determine the effects of different anaesthesia on the postoperative gastrointestinal motility after cholecystectomy. Postoperative gastrointestinal motility were recorded continuously by means of gastrointestinal manometry in 20 patients subject to cholecystectomy (general anaesthesia 10, epidural anaesthesia 10). Normal migrating motor complex (MMC) was abolished during the early postoperative period in all patients. The time of reappearance of intestinal MMC varied from 0.5 to 2 hours . Gastric MMC recurred 5.5 to 14 hours postoperatively and the normal MMC completely recovered 22 to 43 hours after the operations. Ingestion of food changed the MMC into a fed pattern during the early postoperative period. There was no difference between the general anaesthesia group and epidural anaesthesia group in terms of gastrointestinal motility. The results indicate that postoperative gastrointestinal motility recovers faster than that was thought conventionally. Cholecystectomy under general anaesthesia or under epidural anaesthesia makes no difference in postoperative gastrointestinal motility.
Objective To investigate the effect of cholecystectomy on the induction of large intestine cancer and its mechanism. Methods After cholecystectomy, the large intestine neoplasm in mice was induced with dimethylhydrazine(DMH).The histogenesis and growth pattern of large intestine cancer were observed.The Sphase fraction (SPF) of epithelium cells in large intestine mucosa was determined using flow cytometry. Before and after operation, the feces of mice were collected to determine the cholic acid (CA), chenodeoxycholic acid (CDCA), deoxycholic acid (DCA) and lithocholic acid (LCA) concentration by highperformance liquid chromatography. Results The average number of large intestine neoplasms per mouse,percentage of large intestine adenomas in examined mice and SPF of experimental group were significantly higher than those of control group (P＜0.05). The fecal LCA concentration in postcholecystectomy was significantly higher than that in precholecystectomy and in sham operation group (P=0.00). Conclusion The large intestine neoplasm of mice induced by DMH is increased and the proliferation of epithelium cell in large intestine mucosa is increased after cholecystectomy. This suggests that cholecystectomy has promoting effect on induction of large intestine neoplasm in mice. The gut may deal with the increased secondary bile acid(LCA) concentration postcholecystectomy.
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.
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.
The present study was designed to elucidate the role of apoE polymorphism in the lithogenesis of cholecystolithiasis and to explore the hereditary pathogenesis of the disease. Polymerase Chain Reaction (PRC) was used as researching apoE phenotypes and allele frequencies in patients with gallstones (n=87) and in controls (n=50), and the fasting serum lipids of subjects were also measured. The characteristics of lipid variants were analysed among the patients with different apoE phenotypes. The results showed that the levels of TG (1.43mmol/L), VLDL-C(0.68mmol/L) in E2/3 patients were greatly higher than those in E2/3 controls (1.06mmol/L, Ｐ＜0.05 and 0.48mmol/L, Ｐ＜0.05), and LDL-C (1.41mmol/L) was markably lower in E2/3 patients than that in controls (2.04mmol/L, Ｐ＜0.05). The levels of serum lipids decreased significantly in E3/3 patients with HDL-C (0.89mmol/L), HDL2-C (0.49mmol/L), HDL3-C (0.39mmol/L), and compared with those in E3/3 controls (1.28mmol/L Ｐ＜0.05, 0.73mmol/L Ｐ＜0.001 and 0.55mmol/L Ｐ＜0.001). In E3/4 patients there were only slight changes of VLDL-C, LDL-C level. The results suggest that the average level of serum lipids in the same apoE phenotype patients with gallstones is higher than that in controls, and the different apoE phenotypes patients with gallstones have different characteristics of dyslipidemia. ε2 allele is probably one of the dangerous factor in the lithogenesis of cholecystolithiasis.
