ObjectiveTo systematically review the effectiveness and safety of transurethral ureteroscopy lithotripsy in the treatment of upper ureteral calculi. MethodsWe electronically searched The Cochrane Library (Issue 3, 2013), PubMed (1966 to 2013.8), EMbase (1990 to 2013.8), CNKI (1949 to 2013.9), CBM (1978 to 2013.9), VIP (1989 to 2013.8) and WanFang Data (1990 to 2013.8) for the randomized controlled studies (RCTs) related to retroperitoneoscopy ureterolithotomy versus transurethral ureteroscopy lithotripsy for upper ureteral calculi. Two reviewers independently screened literature, extracted data, and evaluated methodological quality of included studies. Then meta-analysis was performed using RevMan 5.2 software. ResultsA total of 16 RCTs involving 1 410 patients (transurethral ureteroscopy lithotripsy:747 cases; etroperitoneal laparoscopic ureterolithotomy:663 cases) were included. The results of meta-analysis showed that, transurethral ureteroscopy lithotripsy was lower than retroperitoneoscopy ureterolithotomy in success rates of surgery (OR=0.26, 95%CI 0.14 to 0.51), 3-day stone clearance rates (OR=0.06, 95%CI 0.03 to 0.11), and 1-month stone clearance rates (OR=0.21, 95%CI 0.08 to 0.53), while it showed superiority in operation time (MD=-22.35, 95%CI-35.29 to-9.41) and postoperative hospital stay (MD=-1.84, 95%CI-3.44 to-0.24). ConclusionCurrent evidence shows that, in the treatment of upper ureteral calculi, transurethral ureteroscopy lithotripsy causes less operation time and postoperative hospital stay, but it had no advantage in success rates of surgery, 3-day stone clearance rates, and 1-month stone clearance rates.
ObjectiveTo summarize experience of endoscopic reverse biliary tract stent placement via choledochus in treatment of situs inversus totalis complicated with choledocholithiasis.MethodThe clinical data of one patient with situs inversus totalis complicated with choledocholithiasis in the Department of Tumor Surgery of Lanzhou University Second Hospital were retrospectively analyzed.ResultsThe ERCP was failed at the first admission, followed by the cholecystectomy plus choledocholithotomy plus T-tube drainage, the stones were removed. Two months later, choledochoscopy revealed multiple choledocholithiasis, then the holmium laser lithotripsy and bile duct stent placement was performed at the secondary admission, the postoperative recovery was good, it had been more than 2 months after the surgery, no stone recurrence occurred.ConclusionEndoscopic reverse biliary tract stent placement via choledochus is feasible, which can be used as an option for treatment of patient with situs inversus totalis complicated with choledocholithiasis.
Objective To investigate the clinical applications of plasma shock wave lithotripsy （PSWL） in the treatment of calculi via choledochoscope. Methods Between 2004 and 2009, 56 huge residual calculi (54 cases) were underwent PSWL via choledochoscope treatment in our hospital. Calculi size: diameter ≤10 mm in 9 calculi, 10 mm lt;diameter ≤15 mm in 24 calculi, 15 mm lt;diameter ≤20 mm in 17 calculi, and diameter gt; 20 mm in 6 calculi. Twenty four cases of these 54 patients had bile duct stricture. Procedure: Firstly found the calculus, and then the lithotriptor wire was introduced to the place 0.5-1.0 mm far away from the calculus surface through choledochoscope channel, and powered on, fired, destructed. Results Forty-eight cases of 54 patients were cured by PSWL with 1 times, 2 cases with 2 times, 2 cases with 3 times, and 2 cases with 4 times. Shock 4-300 times were exported per PSWL, with an average of 65 times. Crushing each stone needed shock for 4-680 times, with an average of 77 times. The calculi were ruptured in different degrees by PSWL, of which 20 cases were completely ruptured. All calculi were completely extracted. Except one case with bile duct stricture was found a small amount of bile duct bleeding during operation, all other patients had no operation complications. Conclusion PSWL technique plays an important role in lithotripsy. It is easy to deal with intrahepatic impacted calculi by PSWL, especially the pigment stones with rough surface.

Objective To evaluate the efficacy of direct vision guided lithotripsy with SpyGlass DS in the treatment of pancreatic duct obstruction caused by chronic calcified pancreatitis and pancreatic duct stones. Methods The clinical data of 9 patients with chronic calcified pancreatitis and pancreatic duct stone who underwent direct-vision guided pancreatic duct stone lithotripsy with SpyGlass DS from July 2017 to September 2017 in the Department of Gastroenterology of Jilin People’s Hospital were retrospectively analyzed, then assessment of technical success rate, clinical success rate, and incidence of adverse event were performed. Results A total of 13 times of intervention were performed in 9 patients, the overall technical success rate of SpyGlass DS direct vision lithotripsy and drainage was 88.9% (8/9). Three of the 9 patients (30.3%) had adverse reactions, including self-limiting bleeding after sphincterotomy (n=1), post-encoscopic retrograde cholangio-pancreatography pancreatitis (n=2), and mild abdominal pain (n=2). Nine patients were followed-up for 3－50 months (median of 21 months), 8 patients (88.89%) reported improvement in abdominal pain, and the mean visual analogue scale score decreased from 6.22±1.47 to 2.78±1.23, P<0.01. Eight patients (88.9%) patients achieved clinical success. Conclusion The SpyGlass DS direct vision-guided lithotripsy is safe and effective for patients with pancreatic duct stones.
Objective To explore the value of endoscopic retrograde cholangiopancreatograph (ERCP) and extracorporeal shock wave lithotripsy (ESWL) in the treatment of pancreatic duct stones. Methods A retrospective collection of 28 patients with chronic pancreatitis and pancreatic duct stones admitted to the Department of Gastroenterology from January 2010 to August 2021 was performed. According to the treatment of patients, they were divided into ERCP direct stone extraction group and ESWL combined ERCP stone extraction group. We compared the treatment effects of the two groups of patients, including the success rate of stone extraction, postoperative complications of ERCP, postoperative symptom improvement, and so on. Results Among the 28 patients, 19 cases underwent ERCP direct stone extraction, and 9 cases underwent ESWL combined with ERCP stone extraction. In the ERCP direct stone extraction group, 7 cases (36.84%) were completely extracted, 1 case was partially extracted (5.26%), and 11 cases (57.89%) failed to extract and only placed stents and drained; 5 cases (26.32%) had elevated white blood cells at 6 hours postoperatively, C-reactive protein increased in 4 cases (21.05%), 3 cases (15.79%) were diagnosed as ERCP-related pancreatitis, and 2 cases (10.53%) were diagnosed as hyperamylaseemia. The abdominal pain symptoms were completely relieved in 14 cases (73.68%) during a follow-up period of 3 to 6 months. The body mass of 17 cases (89.47%) increased in the 6 months after stone extraction. ESWL combined with ERCP had complete stone extraction in 5 cases (55.56%), partial stone extraction in 3 cases (33.33%), and failure in stone extraction and only stent drainage in 1 case (11.11%). One case (11.11%) had elevated white blood cells at 6 hours postoperatively, and 1 case (11.11%) had elevated C-reactive protein . One case (11.11%) was diagnosed with ERCP-related pancreatitis. One case (11.11%) got abdominal pain and transient hematuria during ESWL, which resolved spontaneously 3 days later. After 3 to 6 months of follow-up, 9 patients (100%) had complete relief of abdominal pain symptoms, and the body mass of 9 patients (100%) increased in the 6 months after stone extraction. The stone clearance rate of the ESWL combined with ERCP stone extraction group was higher than that of the ERCP direct stone extraction group (P=0.033), but there was no statistically significant difference between the two groups in terms of ERCP-related complications, relief of abdominal pain, and weight gain (P>0.05). Conclusion ESWL combined with ERCP in the treatment of chronic pancreatitis complicated with pancreatic duct stone extraction is more effective than ERCP direct stone extraction.
