Four hundred and twenty six laparoscopic cholecystectomy(LC)were peformed on patients with acute and subacute cholecystitis,including ①emergency LC(59 patients),②selected LC(215 patients following administration of antibiotic and antispasmotic drugs for 10-15days),and ③selected LC(152 patients with mild biliary colic without any medication).Operative findings were ①congestion and edema of the gallbladder(208cases,11 of them were achieved laparocystectomy),②impaction of stones in the cystic infundibulum or duct with hydrops of gallbladder(142 cases,14 of them were achieved by laparocystectomy),and ③gangrene or empyema of gallbladder(76 patients,20 of them were achieved by laparocystectomy).LC was done successfully on 377 cases,conversion to open surgery was 45 cases (10.6%),severe complication occured on 4 patients for LC(reoperation,0.9%).The quthors believe that LC for patients with acute and subacute cholecystitis issafe and suitable,but LC cannot replace the classical laparocystectomy.
ObjectiveTo investigate clinical value of MRI examination in diagnosis of xanthogranulomatous cholecystitis (XGC), and to analyze pathologic correlation of various imaging findings.
MethodsMRI imaging data of 7 patients with XGC proved by surgery and pathology who underwent entire MRI sequences examination in Sichuan Provincial People's Hospital from Jan. 2013 to Dec. 2015, were analyzed retrospectively. The thickness and contrast enhancement of gallbladder wall, gallbladder wall nodules, completeness of gallbladder mucosa lines, gallbladder stones, and the changes around the gallbladder were focused in every patient.
ResultsIn 7 patients with XGC: gallbladder wall thickening occurred in all patients, in which 2 patients were local thickening, 5 patients were diffuse thickening; ‘hypodense band sign' was found by enhance scan in 4 patients; the multiple intramural nodules were presented in 5 patients, which were low signal intensity on T1WI image and high signal intensity on T2WI image; the mucosal lines were continuous in 6 patients and discontinuous in 1 patient; 6 patients combined with cholecystolithiasis. The fat layer around the gallbladder was found fuzz in 7 patients, liver and gallbladder boundaries were not clear in 7 patients; temporal enhancement of arterial phase in liver parenchyma was observed in all patients, and 1 patient combined with liver abscess. Hilar bile duct narrowed and intra-hepatic bile duct dilated in 2 patients, intra-hepatic and extra-hepatic bile duct slightly dilated in 2 patients (lower part of the choledochus stone was found in 1 patient), liver cyst was observed in 3 patients, single or double kidney cyst was observed in 4 patients; all patients were not found intraperitoneal or retroperitoneal swelling lymph nodes.
ConclusionMRI examination can accurately describe various imaging features of XGC, so MRI has important value in diagnosis of XGC.
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 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.
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.
Objective
To explore the feasibility of single incision laparoscopic cholecystectomy in the treatment of acute cholecystitis, and to provide evidence based medicine for clinical treatment.
Methods
A total of 160 cases of acute cholecystitis who received treatment in our hospital from Jan. 2012 to Dec. 2015 were randomly divided into single incision group (n=80, received single incision laparoscopic cholecystectomy) and three incisions group (n=80, received three incisions laparoscopic cholecystectomy). The clinical and laboratory indexes were compared between the 2 groups.
Results
Compared with the three incisions group, there were statistically significant differences in the operation time, incision pain score, and subjective satisfaction, which were better in single incision group (P<0.05). But there was no significant difference in the blood loss, bed time, anal exhaust time, recovery time of intestinal peristalsis, hospitalization time, incidence of complication (including abdominal infection, bile duct injury, biliary fistula, and incision infection), ratios of T cell subsets (including CD3, CD4, and CD8 T cell), levels of immunoglobulin (including IgA, IgG, and IgM), and level of C reactive protein (P>0.05).
Conclusions
The effectiveness of single incision laparoscopic cholecystectomy is as good as three incisions laparoscopic cholecystectomy, but this single incision laparoscopic surgery is difficult, and its indications should be cautious. Single incision laparoscopic cholecystectomy is more suitable for patients undergoing elective cholecystectomy.
ObjectiveTo explore the therapeutic effect and its possible mechanisms of somatostatin combined with antibiotics on acute cholecystitis through the detection of serum tumor necrosis factor-α (TNF-α) and C-reactive protein (CRP) in rabbits. MethodsForty-five rabbits were randomly averagely classified into three groups following the establishment of acute cholecystitis model: control group, blank group， and experimental group. The rabbits in control group received cefazolin sodium and metronidazoie by intravenous injection twice a day. The rabbits in experimental group got a hypodermic injection of somatostin (20 μg/kg) twice a day besides antibiotics, while these drugs were replaced by equal volume of normal saline for the rabbits in control group. The concentrations of serum TNFα and CRP were detected by enzyme-linked immunosorbent assay and histomorphological and electron microscopic changes of gallbladder in rabbits were observed on 3 d after administer. ResultsThe concentrations of serum TNF-α of rabbits in experimental group 〔(401.6±48.7) pg/ml〕 were significantly lower than those in control group 〔(767.3±67.4) pg/ml〕 and blank group 〔(806.7±61.2) pg/ml〕, P=0.000 and P=0.000, while the difference between the latter two groups was not significant (P=0.196). The concentrations of serum CRP of rabbits in experimental group 〔(16.2±1.1) mg/L〕 were significantly lower than those in control group 〔(55.4±1.2) mg/L〕 and blank group 〔(72.8±8.9) mg/L〕, P=0.000 and P=0.000, and which was higher in blank group compared with control group (P=0.018). The Histopathological results showed that gallbladder wall emerged mulifocality mucosal fluid necrosis, lamina propia hyperemia, bulk neutrophil infiltration and sequent alleviation of reaction in the rabbits of experimental group when compared with the rabbits of blank group and control group. Electron microscopic results demonstrated that the intercellular junction of gallbladder kept relative integrity and the swelling and vacuolar degeneration of mitochondria and endoplasmic reticulum obviously relieved. ConclusionsSomatostatin can significantly reduce the concentrations of serum TNF-α and CRP in the model of rabbits acute cholecystitis, which may protect the mucous membrane of gallbladder from the inflammation reaction.
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.
【Abstract】Objective To investigate the features of gallbladder carcinoma in two-phase spiral CT, and to analysis the values of two-phase spiral CT for the differential diagnosis between gallbladder carcinoma and chronic cholecystitis. Methods The two-phase spiral CT manifestations of 30 cases of gallbladder carcinoma, proved by surgery and pathology, and 30 cases of chronic cholecystitis were analyzed. Results According to the CT findings, the gallbladder carcinoma was categorized into 3 types: intraluminal mass of gallbladder in 6 out of 30 (20.0%）， thickening of the gallbladder wall in 11 (33.7%), and mass replacing the normal gallbladder in 13(43.4%). The most common enhancement patterns of the wall in gallbladder carcinoma were hyperattenuation during the arterial phase, while isoattenuation with the adjacent hepatic parenchyma during the venous phase; or hyperattenuation during both phases. The most common enhancement pattern of the wall in chronic cholecystitis was isoattenuation during both phases, with clear hypoattenuation linear shadow in the gallbladder fossa. Other ancillary features of gallbladder carcinomas included: infiltration of the adjacent parenchyma, local lymphadenopathy and intrahepatic metastasis. Conclusion Two-phase spiral CT scan can identify the features of the gallbladder carcinoma and is helpful for the differential diagnosis of these two different disease entities.
Objective To summarize the clinical therapeutic efficacy of emergent laparoscopic cholecystectomy （LC） and emergent open cholecystectomy （OC）. Methods One hundred and thirty-three patients with acute cholecystitis from March 2011 to June 2012 in this hospital were randomly divided into emergent LC （ELC） group and emergent OC （EOC） group. The examination and treatment before and after operation were the same. The clinical data before and during operation， postoperative complications， and recovery conditions were observed and compared. Results There was no obvious difference of the clinical data before operation between the ELC group and EOC group （P＞0.05）. Also， there were no significant differences of the operation time， biliary duct injury rate， postoperative bleeding rate， and reoperation rate in two groups （P＞0.05）. The time of postoperative anal exsufflation， time of out-of-bed activity， and postoperative hospital stay in the ELC group were significantly shorter than those in the EOC group （P＜0.05）， the poor incision healing rate in the ELC group was significantly lower than that in the EOC group （P＜0.05）， and the intraoperative blood loss in the ELC group was significantly less than that in the EOC group （P＜0.05）. Conclusions ELC as compared with EOC， are less intraoperative blood loss， less postoperative complications， more rapid recovery， and do not increase operation time. In a hospital with skilled LC technique， ELC is safe and feasible， has obvious advantages of minimal invasion.
