ABSTRACT
Objective To investigate the short term efficacy and security of different diameters of ampulla balloon dilation in the treatment of choledocholithiasis. Methods 80 patients with extrahepatic bile duct stones treated by EPBD were included in this study. All the patients were divided into 8 mm group, 10 mm group, 12 mm group, 14 mm group, which were according to the diameter of common bile duct (CBD) and stones. CBD stones were removed with retrieved balloon, Dormia basket, and/or mechanical lithotripsy if necessary. The incidence of 24 h hemorrhage, acute pancreatitis, hyperamylasemia and intestinal perforation were observed, and the incidence of pneumobilia and duodenobiliary reflux two weeks after EPBD. Then analyzed the short-term efficacy of the four groups. Result The overall success of stone removal in all groups were 100.0%, there was no significant differences in bleeding, intestinal perforation, hyperamylasemia, pancreatitis between each group (P > 0.05) . There shows significant differences in pneumobilia and duodenobiliary reflux two weeks after EPBD (P < 0.05). The incidence of pneumobilia and duodenobiliary reflux increased with the size of the balloon. Conclusion The application of EPBD is effective and safe for bile duct stone removal, while with the increasing of balloon diameter, the function of Oddi sphincter has severely influenced.
ABSTRACT
Objective To assess the optimal timing of laparoscopic cholecystectomy ( LC ) in mild acute gallstone pancreatitis ( mAGP) .Methods From May 1, 2012 to August 30, 2015, consecutive patients with mAGP were prospectively assessed.Each patient underwent abdominal computed tomography scan within 48 h after mAGP onset to assess the presence of peripancreatitc fluid collection, and Marshall score was used to assess if there was organ failure.Patients with neither peripancreatic fluid collection by CT ( classified as grade A, B or C based on the Balthazar CT grading system) nor organ failure by clinical data (Marshall score <2) were randomized according to simple randomization into early laparoscopic cholecystectomy ( ELC; LC performed within 7 days after a pancreatitis attack, without waiting for symptom resolution) or late laparoscopic cholecystectomy ( LLC; LC performed ≥7 days following an attack, with complete remission of AGP symptoms) group.The mean LC operation time, bleeding during LC, post-LC complications and lengths of hospital stay between the ELC group and LLC group were compered.Results The study enrolled 102 patients with mAGP.A total of 49 and 53 patients were assigned to ELC and LLC group, respectively.The mean LC operation time and lengths of hospital stay were significantly shorter in the ELC group than in the LLC group [(19.9 ±5.3) vs(31.1 ±8.4) min;(7.9 ±1.8) vs (16.8 ±5.3) d, P<0.05], while there were no significant difference on bleeding during LC and post-LC complications.Conclusions LC for patients with mAGP who had neither peripancreatic fluid collection nor organ failure within 7 days after the onset was safe and feasible.
ABSTRACT
Objective To study the Effect of acute peripancreatitc fluid collection and pancreatic necrosis to the prognosis of acute pancreatitis.Methods Retrospectively analyzing the prognostic effect of acute peripancreatitc fluid collection and pancreatic necrosis according to the early Computed-Tomograghy of 323 consecutive acute pancreatitis patients from Jan 2003 to Dec 2007,the end points are systemic inflammation response syndrome ( SIRS),pancreatic infection,and mortality.Results Within 5d after onset,97 of 323 cases (30%) presented with SIRS and lasted more than 2d,12 cases (3.7%) occurred pancreatic infection during middle or late phase,14 cases died,the mortality is 4.3%.141 of 323 cases (43.7%) who had acute peripancreatic fluid collection presented with SIRS,acute peripancreatic fluid collection correlated significantly with the occurrence of SIRS,P ＜ 0.05.227 cases (277/323,85.8%) had no pancreatic necrosis,no pancreatic infection occurred,46 cases (46/323,14.2% )had pancreatic necrosis,pancreatic necrosis correlated significantly with pancreatic infection,P ＜ 0.05.Conclusions Acute poripancreafic fluid collection and pancreatic necrosis had different prognostic effect to acute pancreatitis.Acute peripancreatic fluid collection correlated well with the occurrence of SIRS during the early phase;Pancreatic necrosis may be infected during middle or late phase of acute pancreatitis,more extent of pancreatic necrosis,more possible that pancreatic infection will occur.
ABSTRACT
Objective To explore clinical methods for preventing the recurrence of biliary pancreatitis.Methods Clinical data of 112 consecutive cases of acute biliary pancreatitis from January 1999 to July 2001 treated in this hospital were analyzed retrospectively.Before admission all the patients had no history of biliary pancreatitis or cholecystectomy.According to whether or not an endoscopic sphincterotomy(EST) or cholecystectomy was given,the patients were divided into 4 groups: Conservative Group(n=45),EST Group(n=22),Cholecystectomy Group(n=29),and Combination Group(n=16).The recurrence rates of pancreatitis of the 4 groups were compared each other.Results The 112 patients were followed for 16~30 months(mean,18.5 months).Recurrence of pancreatitis was found in 12 patients in the Conservative Group(26.7%,12/45) and in 2 patients in the Cholecystectomy Group(6.9%,2/29).No recurrence was seen in the EST Group and the Combination Group.As compared with the Conservative Group,both EST and cholecystectomy significantly decreased the recurrence rate of biliary pancreatitis.The 2 recurrent patients in the Cholecystectomy Group were given an endoscopic retrograde cholangiopancreatography(ERCP),by which small common bile duct calculi were found.Conclusions Common bile duct calculus is the major cause of recurrence of biliary pancreatitis.Both EST and cholecystectomy can decrease the recurrence rate of biliary pancreatitis.EST is suitable for elderly high-risk patients because of its minimal invasion.
ABSTRACT
Objective To explore the indications and efficacy of endoscopic papillary balloon dilation(EPBD) in the management of choledocholithiasis. Methods EPBD combined with a retrieval basket or balloon or both was performed to remove common bile duct stones in 42 cases from April 1999 to August 2001. The length and maximum diameter of the balloon were 5 0cm and 1 2cm respectively. The number of common bile duct stones must be less than 3, and the diameter must be less than or equal to 1 0cm. The balloon was inflated at pressure of (8～12)atm for 2min two times and the corresponding dilated diameter was 1 0cm～1 2cm. Results EPBD was performed successfully in all patients. The common bile duct stones were removed in 40 out of 42 patients, including endoscopic sphincterotomy(EST) in 4 patients, with the success rate being 95 2%(40/42). Stone removal failed in 2 patients. 3 cases had mild pancreatitis postoperatively. No complications such as bleeding or intestinal perforation occurred. Conclusions It is suitable to treat common bile duct stones by EPBD when the number of stones is less than 3 and the diameter is less than or equal to 1.0cm.
ABSTRACT
Objective [WT5”BZ] To evaluate the role of duodenoendoscopy in the diagnosis and treatment of acute pancreatitis with gallstone (AP).[WT5”HZ] Methods [WT5”BZ] 45 AP cases were randomized into group of endoscopic retrograde cholangiopancreatography (ERCP) (n=20) and non ERCP group (n=25). All patients were further stratified into mild and severe subgroups according to APACHE Ⅱ scores. All cases were given supportive treatment combined with traditional Chinese medicine. The patients in ERCP group received ERCP within 24 hours of admission. If stones were found, endoscopic sphincterotomy (ES) was performed to extract the stones by basket. In cases with multiple stones or if no stone could be immediatly identifiable, endoscopic naso billiary drainage (ENBD) was applied.[WT5”HZ] Results [WT5”BZ]In patients with severe AP, the morbidity, length of hospital stay and cost were significantly lower in ERCP treatment subgroup than those without ERCP treatment (all P
