This study aimed to verify the Tokyo guidelines for the management of acute cholangitis and cholecystitis of 2007 edition (TG07) in patients with obstructive cholangitis due to benign and malignant diseases. METHODS: The patients were retrieved from our existing ERCP database. Final diagnosis of acute cholangitis was made by detecting purulent bile during biliary drainage. We examined and compared the guidelines concerning benign and malignant obstruction. RESULTS: In 120 patients in our study, 82 and 38 had benign and malignant biliary obstruction, respectively. Guidelines based diagnosis was made in 68 (82.9%), 36 (94.7%), and 104 (86.7%) patients with benign, malignant, and overall biliary obstruction, respectively, which were significantly higher than 44 (53.7%), 17 (44.7%), and 61 (50.8%) diagnosed by Charcot’s triad (P【0.001). Treatment consistent with the guidelines was offered to 58 (70.7%) patients with benign obstruction and15 (39.5%) patients with malignant obstruction (P=0.001). No significant association was observed between clinical compliance, guidelines-based severity grades and clinical outcomes. In the multivariate model, intrahepatic obstruction (OR=11.2, 95% CI: 1.55-226.9) and hypoalbuminemia (≤25.0 g/L; OR=17.3, 95% CI: 3.5-313.6) were independent risk factors for a 30-day mortality. CONCLUSIONS: The TG07 are more reliable than Charcot’s triad for the diagnosis of acute cholangitis albeit with limited prognostic values. Intrahepatic obstruction and hypoalbuminemia are new predictors of poor prognosis and need further assessment.展开更多

文摘BACKGROUND Gangrenous cholecystitis is a form of acute cholecystitis which involves gangrenous alterations in the gallbladder wall and it often follows an acute and serious course.We herein report on two cases of very elderly people diagnosed early with gangrenous cholecystitis,who safely underwent laparoscopic cholecystectomy(LC)and both demonstrated a good outcome.CASE SUMMARY Case 1:An 89-year-old female.She underwent abdominal contrast-enhanced computed tomography(CECT)due to abdominal pain and diarrhea.Her gallbladder wall indicated the absence of contrast enhancement,thus leading to diagnosis of gangrenous cholecystitis and she therefore underwent LC.Although her gallbladder demonstrated diffuse necrosis and it was also partly perforated,she was able to be discharged without any serious complications.Case 2:A 91-year-old female.She made an emergency visit with a chief complaint of abdominal pain.Abdominal CECT revealed swelling of the gallbladder and an ambiguous continuity of the gallbladder wall.She was diagnosed with gangrenous cholecystitis and underwent LC.Her gallbladder had swelling and diffuse necrosis.Although her preoperative blood culture was positive,she showed a good outcome following surgery.CONCLUSION Although a definite diagnosis of gangrenous cholecystitis is difficult to make prior to surgery,if an early diagnosis can be made and appropriate treatment can be carried out,then even very elderly individuals may be discharged without major complications.
