【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.
ObjectiveTo explore the etiological agent, clinical manifestations, imaging findings, pathologic characteristics, diagnosis, treatment, and prognosis of xanthogranulomatous cholecystitis(XGC). MethodThe clinical data of 48 patients with XGC diagnosed by postoperative pathology from January 2003 to December 2012 were collected and analyzed. ResultsIn these 48 patients with XGC, the clinical manifestations included 40(83.3%)patients with upper right abdominal pain, 18(37.5%)patients with jaundice, 12(25.0%)patients with fever. B ultrasound examination was performed in 45 cases, in which 42 cases were diagnosed with cholecystitis, 38 cases together with cholecystolithiasis, 15 cases together with cholecystolithiasis and gallbladder neoplasm, and 3 cases together with choledocholith with bile duct dilatation. CT was performed in 30 cases, in which 25 cases were diagnosed with cholecystitis together with cholecystolithiasis, 11 cases were diagnosed with gallbladder neoplasm. MRI was performed in 22 cases, in which 18 cases were diagnosed with cholecystitis together with cholecystolithiasis, 4 cases were diagnosed with gallbladder carcinoma. Thirty-three cases were treated with open cholecystectomy, 9 patients with laparoscopic cholecystectomy, 4 patients with cholecystectomy plus choledocholithotomy and T-tube drainage, 2 patients with cholecystectomy plus partial hepatectomy. All the patients were diagnosed with XGC by postoperative pathology and recovered well without recurrence and canceration. ConclusionsXGC is a kind of benign and invasive disease without specific clinical manifestation. Bultrasound, CT, or MRI play an important role in diagnosis, but final diagnosis is mainly based on pathological detection, and surgery is the most effective treatment. The prognosis of XGC is favorable if gallbladder is completely resected.
【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.
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.
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.
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 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.
Objective To investigate the diagnostic value of CT scanning and MR imaging on acute cholecystitis. Methods The CT or MR imaging data of 21 patients with proved acute cholecystitis were retrospectively reviewed. Eleven patients were examined with contrast-enhanced multi-detector-row spiral CT scanning and other 10 cases underwent contrast-enhanced MR imaging. Results Nineteen patients showed obscure gallbladder outlines （90.5%）. The gallbladder wall demonstrated even thickening in 15 patients （71.4%） and irregular thickening in 6 cases （28.6%）. All patients showed inhomogeneous enhancement of the gallbladder wall （100%）. The bile was hyper-dense or hyper-intense on T1W image in 11 cases （52.4%）. Ten cases had free peri-cholecystic effusion （47.6%）, and 16 cases had peri-cholecystic adhesive changes or fat swelling （76.2%）. Patchy or linear-like transient enhancement of the adjacent hepatic bed in the arterial phase was seen in 16 cases （76.2%）. Twelve patients developed pleural effusion, or ascites, or both （57.1%）. Gallbladder perforation complicated with peritonitis was seen in one case, micro-abscess formation and pneumocholecystitis was observed in another case, and one case had gallbladder diverticulum. Conclusion Wall blurring, pericholecystic adhesion or fat edema, and transient enhancement of adjacent hepatic bed in the arterial phase are the imaging findings specifically associated with acute cholecystitis, which are readily appreciated on contrast-enhanced multi-phasic CT and MR scanning.
ObjectiveTo investigate the efficacy and safety of percutaneous transhepatic gallbladder drainage (PTGBD) combined with early laparoscopic cholecystectomy (LC) in the treatment of elderly patients with high-risk acute cholecystitis.MethodsThe clinical data of 128 elderly patients with high-risk acute cholecystitis admitted to Department of Hepatobiliary Surgery in Dazhou Central Hospital from January 2015 to January 2019 were retrospectively analyzed. Among them, 62 patients underwent PTGBD combined with early LC treatment (PTGBD+early LC group), 66 patients underwent PTGBD combined with delayed LC treatment (PTGBD+delayed LC group). Comparison was performed on the operative time, intraoperative blood loss, conversion to laparotomy rate, postoperative indwelling time, postoperative hospitalization time, total hospitalization time, and complication.ResultsPTGBD was successfully performed in all patients, and the symptoms were relieved within 72 hours. There was no significant difference in operative time, intraoperative blood loss, conversion to laparotomy rate, postoperative indwelling time, postoperative hospitalization time, and total complication rate between the two groups (P>0.05), but the total hospitalization time of the PTGBD+early LC group was shorter than that of the PTGBD+delayed LC group (P<0.001). There was no second operation and death in both two groups. The 128 patients were followed-up for 2–50 months with a average of 19 months. Results of follow-up after operation showed that the patients did not complain of obvious abdominal pain, abdominal distension, chills, fever, jaundice, and other discomforts.ConclusionsFor elderly patients with high-risk acute cholecystitis, early LC is a safe and effective treatment for patients with good overall condition after PTGBD. It can not only shorten the total hospitalization time, but also significantly shorten the time of tube-taking and improve the quality of life of patients. It has important clinical application value.
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.
