【Abstract】Objective To analysis the clinical characteristics, pathogenesis, diagnosis and treatment of acute acalculous cholecystitis.Methods Seventy-nine cases of acute acalculous cholecystitis from January 1996 to January 2003 were retrospectively reviewed.Results Of those 79 cases, 13 cases were treated nonoperatively and 66 cases were treated operatively. Twentythree cases were suppurative, 43 cases were gangrenous with perforation in 18 cases，which were proved by postoperative pathology. Seventysix cases were cured and 3 cases were dead. Conclusion Keeping vigilant alert, observing dynamically as well as appropriate operative intervention are effective to improve the prognosis of acute acalculous cholecystitis.
ObjectiveTo explore technical essentials and safety of laparoscopic cholecystectomy (LC) guided by gallbladder ampulla localization on an imaginary clock for cholecystitis.MethodsA retrospective study of 8 707 continuous patients with mild cholecystitis who underwent LC from July 1998 to February 2018 at a single institution was conducted. Among them, 3 168 patients were treated by the traditional LC from July 1998 to February 2007 (a traditional LC group), 5 539 patients were treated by the LC with the guidance of the gallbladder ampulla localization on an imaginary clock from March 2007 to February 2018 (a gallbladder ampulla localization group). The conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury, operative time, intraoperative blood loss, and postoperative hospital stays were compared between the traditional LC group and the gallbladder ampulla localization group.ResultsThere were no significant differences in the gender, age, course of disease, and type of cholecystitis between these two groups (P>0.050). The rates of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding, bile leakage without bile duct injury and the operative time, intraoperative blood loss and postoperative hospital stays in the traditional LC group were 3.00% (95/3 168), 0.13% (4/3 168), 0.09% (3/3 168), 0.03% (1/3 168), (43.6±12.6) min, (18.7±3.3) mL, (3.6±2.7) d, respectively, which in the gallbladder ampulla localization group were 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), 0 (0/5 539), (32.2±10.5) min, (12.4±3.5) mL, (3.5±2.8) d, respectively. The differences of conversion to open surgery, bile duct injury, return to the operating room due to postoperative massive abdominal bleeding rates, and the operative time and intraoperative blood loss were statistically significant between these two groups (P<0.050). The differences of the bile leakage without bile duct injury rate and postoperative hospital stays were not statistically significant between the two groups (P>0.050).ConclusionThis study shows that gallbladder ampulla localization on an imaginary clock is useful for ductal identification so as to reduce bile duct injury and improve safety of LC in case of no conversion to open surgery.
ObjectiveTo explore the clinical characteristic, operation time, and methods of elderly calculous cholecystitis. MethodsThe data of 386 cases of elderly calculous cholecystitis in our hospital from January 2008 to April 2014 were retrospectivly analyzed. ResultsIn 386 patients, 234 cases were chronic cholecystitis, 152 cases were acute calculous cholecystitis; there were preoperative complications in 174 cases (45.08%); 234 cases of chronic calculous cholecystitis patients underwent elective operation, 35 cases in 152 cases of acute phase underwent operation at 72 h, the remaining 117 cases underwent operation in within 2 weeks of onset. Laparoscopic cholecystectomy (LC) were in 283 cases, including transfer laparotomy operation in 8 cases; underwent conventional open cholecystectomy in 103 cases. Postoperative complications occurred in 49 cases, the complication rate was 12.69%, including incision infection, pulmonary infection, acute urinary retention, urinary tract infection, biliary fistula and so on. Three hundreds and eighty-four cases were cured, 2 cases died, for cholecystolithiasis complicated with severe acute cholangitis, died from multi organ failure in 3 days after operation. ConclusionsThe clinical characteristics of elderly calculous cholecystitis is unique. To strictly grasp the operation indication, selection of operation time, take individual operation method with the disease, and strengthen treatment of perioperative period are the key to improve the cure rate and the operation success rate of elderly cholecystitis.
ObjectiveTo study the efficacy and safety of early laparoscopic cholecystectomy with percutaneous transhepatic gallbladder drainage (PTGBD) in the treatment of elderly patients with high risk moderate acute cholecystitis.MethodsThe clinical data of 218 elderly patients with high risk moderate acute cholecystitis admitted to Department of Hepatobiliary Surgery in Dazhou Central Hospital from January 2015 to October 2019 were retrospectively analyzed, including 112 cases in the PTGBD combined with early LC sequential treatment group (sequential treatment group) and 106 cases in the emergency LC group. In the sequential treatment group, PTGBD was performed first, and LC was performed 3–5 days later. The emergency LC group was treated with anti infection, antispasmodic, analgesia, and basic disease control immediately after admission, and LC was performed within 24 hours. The operation time, intraoperative blood loss, conversion to laparotomy rate, postoperative catheter retention time, postoperative anal exhaust time, postoperative hospitalization time, hospitalization cost, incidence of incision infection, and incidence of complications above Dindo-Clavien level 2 were compared between the two groups to evaluate their clinical efficacy and safety.ResultsAll patients in the sequential treatment group were successfully treated with PTGBD, and the symptoms were significantly relieved within 72 hours. There were significant differences in the operation time, intraoperative blood loss, conversion to laparotomy rate, postoperative tube retention time, postoperative anal exhaust time, postoperative hospitalization time, incidence of incision infection, and the incidence of complications above Dindo-Clavien level 2 between the two groups (P<0.05), which were all better in the sequential treatment group, but the hospitalization cost of the sequential treatment group was higher than that of the emergency LC group (P<0.05). There were no cases of secondary operation and death in the 2 groups. After symptomatic treatment, the symptoms of all patients were relieved, without severe complications such as biliary injury and obstructive jaundice. All the 218 patients were followed up for 4–61 months, with an average of 35 months. During follow-up period, 7 patients in the sequential treatment group had postoperative complications, and complications were occurred in 13 patients in the emergency LC group.ConclusionPTGBD is the first choice for elderly high risk moderate acute cholecystitis patients with poor systemic condition and high risk of emergency surgery, but it has the disadvantage of relatively high medical cost.
ObjectiveTo investigate clinical value of magnetic resonance imaging (MRI) in differentiating xanthogranulomatous cholecystitis (XGC) with gallbladder cancer (GBC). MethodsMRI data of 7 patients with XGC and 13 patients with GBC proved by surgery and pathology were analyzed retrospectively. The main contents of the observation included:①Maximum thickness of gallbladder wall; ②Diffuse thickening or localized thickening of gallbladder wall; ③Enhancement pattern (uniform or nonuniform) of gallbladder wall; ④Gallbladder wall sandwiches enhancement; ⑤Gallbladder wall nodules; ⑥Completeness of gallbladder mucosa lines; ⑦Obstruction of biliary tract; ⑧Calculus in gallbladder or bile duct; ⑨Involvement of adjacent liver; ⑩Definition of surrounding fat layer; Lymphadenopathy. ResultsIn above 11 MRI comparing features, these features such as the gallbladder wall sandwiches enhancement, the gallbladder wall nodules, the completeness of gallbladder mucosa lines, the biliary obstruction, and the lymphadenopathy were statistically significant between the XGC and the GBC (P < 0.05), while the rest features such as the maximum thickness of gallbladder wall, the type of gallbladder wall thickening, the gallbladder wall enhancement pattern, the calculus in gallbladder or bile duct, the involvement of adjacent liver, and the definition of surrounding fat layer were not statistically significant between the XGC and the GBC (P > 0.05). ConclusionMRI has important values in differentiating XGC with GBC.
Objective To investigate clinical efficacy of laparoscopic cholecystectomy via left side approach for patients with acute cholecystitis. Methods One hundred and twenty patients with acute cholecystitis from January 2015 to May 2017 were collected. All of the patients were divided into observation group and control group according to the operative mode, with 60 cases in each group. In the observation group, the patients were treated by laparoscopic cholecystectomy via left side approach using the ligation-free technique to the main trunk of the cystic artery; in the control group, the patients were treated by the conventional laparoscopic cholecystectomy. After treatment, the operative situation, postoperative recovery, and incidence of postoperative complications were compared between these two groups. Results Compared with the control group, the operative time, first anal exhaust time, hospitalization stay, leukocytes recovery time, and coagulation function recovery time were shortened and the intraoperative bloods loss was reduced in the observation group, the differences were statistically significant (P<0.05). Furthermore, the overall postoperative complication incidence rate of the observation group was significantly lower than that of the control group (P<0.05). Conclusion For patients with acute cholecystitis, laparoscopic cholecystectomy via left side approach using ligation-free technique to main trunk of cystic artery is reliable and safe, which can effectively improve operative situation, shorten operative time, promote recovery of patient, and reduce incidence of postoperative complications.
ObjectiveTo explore the optimal surgical timing of sequential laparoscopic cholecystectomy (LC) following percutaneous cholecystostomy (PC) in the patients with acute cholecystitis, so as to provide a clinical reference. MethodsThe patients who underwent PC and then sequential LC in the Fifth Affiliated Hospital of Xinjiang Medical University from March 2021 to July 2023 were selected based on the inclusion and exclusion criteria, who were categorized into 3 groups: the short interval group (3–4 weeks), the intermediate interval group (5–8 weeks), and the long interval group (>8 weeks) based on the time interval between the PC and LC. The gallbladder wall thickness before LC, operative time, intraoperative blood loss, postoperative hospitalization time, total hospitalization time, time and cases of drainage tube placement, admission to intensive care unit, conversion to open surgery, occurrence of complications, and total hospitalization costs were compared among the 3 groups. ResultsA total of 99 patients were enrolled, including 25 in the short interval group, 41 in the intermediate interval group, and 33 in the long interval group. The data of patients among the 3 groups including demographic characteristics, blood routine, C-reactive protein, interleukin-6, fibrinogen, international standardized ratio, liver function indicators, and comorbidities had no statistical differences (P>0.05). The gallbladder wall thickness before LC and the operative time, intraoperative blood loss, postoperative hospitalization time, total hospitalization time, time and cases of drainage tube placement, admission to intensive care unit, conversion to open surgery, occurrence of complications, and total hospitalization costs during and after LC had statistical differences among the 3 groups (P<0.05). These indicators of the intermediate interval group were better than those of the other two groups by the multiple comparisons (P<0.05), but which had no statistical differences except total hospitalization costs (P=0.019) between the short interval group and the long interval group (P>0.05). ConclusionAccording to the results of this study, the optimal surgical timing of sequential LC following PC is 5–8 weeks, however, which needs to be further validated by large sample size and multicenter data.
To study the expressions of CA19-9 and CA125 and their clinicopathologic significancesin gallbladder adenocarcinoma , pericancerous tissues and chronic cholecystitis. Methods EnVisionTM immunohistochemist ry was used for assaying the expressive levels of CA1929 and CA125 in the routinely paraffin2embedded sections of specimens f rom gallbladder adenocarcinoma ( n = 108) , pericancerous tissues ( n = 46) , and chronic cholecystitis ( n = 35) . Results The positive rates of CA19-9 and CA125 were significantly higher in gallbladder adenocarcinoma ( 49. 1 % , 51. 9 %) than those in pericancerous tissues ( 26. 1 % , 15. 2 %) and chronic cholecystitis(14. 3 % , 5. 7 %) , respectively ( Plt; 0. 01) . The positive rates of CA19-9 and CA125 were significantly lower in thecases of adenomatous canceration , maximal diameter lt; 2 cm , no-metastasis of lymph node and no-invasion of regional tissues than those in the ones of low-differentiated adenocarcinoma , maximal diameter ≥2 cm , metastasis oflymph node and invasion of regional tissues ( Plt; 0. 05 , Plt; 0. 01 ) . The consistence of CA19-9 and CA125 expressivelevels was found in gallbladder adenocarcinoma (χ2 = 44. 69 , Plt; 0. 01) . Conclusion The expressions of CA19-9 andCA125 may be important tumor markers to reflect the carcinogenesis , progression , biological behaviors and prognosis of gallbladder adenocarcinoma.
ObjectiveTo explore the effectiveness of clinical pathway (CP) in patients underwent laparoscopic cholecystectomy (LC). MethodsA retrospective, case-matched, and clinical controlled study was applied. We selected patients with acute calculous cholecystitis (ACC) who were hospitalized in 363 Hospital and underwent LC between September 2012 and August 2013, and divided them into two groups (non-CP vs. CP:2 to 1) according to sex, age (±5), nation and complications. The indicators including length of stay (LOS), antibiotic usage and per-average hospital expenses were compared between groups. Data were analyzed using SPSS 13.0 software. ResultsA total of 1 044 patients were included, of which 348 were assigned to CP management (CP group), while the other 696 patients were 2 to 1 matched with those in the CP group. Compared to the non-CP group, the pre-operation LOS and total LOS in the CP group were shortened by 1.23 days and 2.08 days, respectively (P < 0.05); the per-average hospital expenses and per-average expenses of drugs in the CP group were decreased by ￥604.7 yuan and ￥287.5 yuan, respectively (P < 0.05); and the rate of antibiotic and non-restricted antibiotic usage in the CP group were dropped by 4.4% and 7.0%, respectively (P < 0.05). There was no significant difference between the groups in efficiency, hospital-related infection rate, the incidence of adverse events, the restricted and special antibiotic usage rate (P > 0.05). The variation coefficient of patients included in the CP group was 15.8%, and the time which did not meet the admission requirement of CP was the main reason for this variation (27, 49.1%). ConclusionClinical pathway could shorten the LOS and cut down the total hospital expenses. However, multidisciplinary cooperation is still needed, and we should optimize the CP processes continuously and enhance the flexibility of CP, so as to improve the quality of medical service.
Objective To evaluate the diagnostic value of analyzing the pattern of gallbladder wall enhancement on MDCT to identify the different causes of acute cholecystitis. Methods In January 2009 to December 2012， 169 patients diagnosed with acute cholecystitis caused by various pathologic conditions were performed MDCT scans， the images of portal venous phase and clinical data were retrospectively reviewed by two blinded radiologists. There were 146 cases in non-hepatopathy cholecystitis group and 23 cases in hepatopathy cholecystitis group. The other 5 normal gallbladder cases diagnosed by MDCT scans were retrospectively reviewed as contrast group. Using five patterns according to the enhancement pattern of flat gallbladder wall thickening on MDCT. The study cases were then divided into five patterns and the thickness of the mucous membrane were measured. The occurrence rate of each pattern and the thickness of the mucous membrane between the groups were compared respectively. Results In the non-hepatopathy cholecystitis group， there were typeⅡin 102 cases （69.9%）， typeⅢin 5 cases （3.4%）， typeⅣ in 30 cases （20.5%）， and typeⅤ in 9 cases （6.2%）. In the hepatopathy cholecystitis group， there were typeⅡin 2 cases （8.7%）， typeⅢ in 11 cases （47.9%）， typeⅣin 5 cases （21.7%）， and typeⅤin 5 cases （21.7%）. The occurrence rate of typeⅡin the non-hepatopathy cholecystitis group was significialtly higher than that in the hepatopathy cholecystitis group （P＜0.005）. The occurrence rate of typeⅢ and typeⅤ in the hepatopathy cholecystitis group were significialtly higher than those in the non-hepatopathy cholecystitis group（P＜0.005， P＜0.05）. The occurrence rate of type Ⅳ between the two groups had no significant difference （P＞0.05）. TypeⅠonly present in the contrast group. The non-hepatopathy group’s mean mucous membrane thickness was （2.61±1.30） mm ， which was thicker than the hepatopathy group’s （2.02±0.52） mm（t=2.22， P＜0.05）. Conclusion Analyzing the enhancement pattern of a thickened gallbladder wall on MDCT is helpful in identifying the causes of acute cholecystitis， and the gallbladder perforation or not.
