We present the case of treatment of choledocholithiasis complicated with obstructive jaundice and acute grade II cholangitis according to Tokyo criteria in the female patient aged 96 years with significant comorbidity. Peroral digital cholangioscopy and laser contact lithotripsy were made. No complications were observed in postoperative period, and the manifestations of cholangitis and obstructive jaundice regressed. In our opinion, high efficacy and safety of the used method are the strong argument for the use in patients with difficult choledocholithiasis who have significant comorbidities during the single-stage endoscopic operation.

Abstract Background Peroral cholangioscopy with intraductal lithotripsy facilitates optically guided stone fragmentation of difficult biliary stones refractory to conventional endoscopic therapy. The aim of this study was to evaluate the efficacy and safety of peroral cholangioscopy with intraductal lithotripsy for difficult biliary stones. Methods Searches of PubMed, EMBASE, Web of Science, and Cochrane databases were performed in accordance with PRISMA and MOOSE guidelines. Measured outcomes included overall fragmentation success, single-session fragmentation and duct clearance, and rate of adverse events. Sensitivity and subgroup analyses were performed based upon cholangioscopy technique and type of lithotripsy (laser versus electrohydraulic). Heterogeneity was assessed with I 2 statistics. Publication bias was ascertained by funnel plot and Egger regression testing. Results 35 studies were included with 1762 participants (43.4 % men; mean age 61.5 [standard deviation (SD) 11.0]). Prior cholecystectomy had been performed in 37 % of patients, with a mean number of 1.6 (SD 0.5) ERCPs performed prior to lithotripsy. Mean stone size was 1.8 (SD 0.3) cm. Peroral cholangioscopy with intraductal lithotripsy achieved an overall stone fragmentation success of 91.2 % (95 %CI 88.1 % – 93.6 %; I 2 = 63.2 %) with an average of 1.3 [SD 0.6] lithotripsy sessions performed. Complete single-session fragmentation success was 76.9 % (95 %CI 71.6 % – 81.4 %; I 2 = 74.3 %). The adverse events rate was 8.9 % (95 %CI 6.5 % – 12.2 %; I 2 = 60.6 %). Mean procedure time for peroral cholangioscopy was 67.1 (SD 21.4) minutes. There was no difference in overall fragmentation rate or adverse events; however, laser lithotripsy was associated with a higher single-session fragmentation rate and shorter procedure time compared with electrohydraulic lithotripsy. Conclusions Peroral cholangioscopy with intraductal lithotripsy appears to be a relatively safe and effective modality for difficult biliary stones.

Calcium oxalate monohydrate (COM) is the primary constituent of the majority of stones formed in the urinary tract. Mechanical properties of renal calculi dictate how a stone interact and disintegrate with mechanical forces produced by shock wave and laser lithotripsy techniques. Tensile stresses may be more effective in some instances in disrupting material because most materials are weaker in tension than compression. Urinary stone containing COM as a major component was subjected to tensile, flexural and compressive strength studies in order to understand its mechanical properties in vitro. The calculated tensile breaking strength for the urinary stone from three tests varies from 0.57 MNm-2 to 1.52 MNm-2. The flexural strength and the flexural modulus of the urinary stone were calculated as 5.17 MNm-2 and 2.22 GNm-2 respectively while the observed compressive strength was 6.11 MNm-2. The chemical composition and the crystalline nature of the stone were verified using Fourier Transform Infrared spectroscopy and X-ray diffraction.
