To confirm the possibility of minimally-invasive laser procedure for fragmentation of stones in the pancreatic duct following the results of laboratory experiments and medical practice. Materials and methods. A fully functional hardware complex consisting of a pulsed laser unit, video endoscopic system and cooling system was created for experimental stone fragmentation in laboratory. The experiments involved microscopic video registration of the fragmentation process, pressure and temperature measurement in the stone area. Pancreatic stones, human and artificial gallstones as well as porcine pancreas were used in the experiments; the gastrointestinal tract was made of silicone, the pancreas was made of gelatin aqueous solution jelly. In clinical practice, a patient with lithiasis of Wirsung's duct was assigned to ultrasound and CT, then endoscopic papillosphincterotomy, endoscopic pancreatoscopy, laser lithotripsy and lithoextraction, pancreatic duct stenting. The procedures involved a laser unit, videoduodenoscope, catheter and their video systems. Results. The laboratory experiments established that effective and safe laser fragmentation of stones from 4 × 7 mm into 0.1–2 mm occurs in the flowing fluid in front of the stone at 1 μs laser pulse duration, 5–15 Hz frequency and 120–150 mJ laser energy. After laser fragmentation of the stone in a patient with virsungolithiasis and removal of fragments from the duct, the patient was discharged from the hospital on the 12th day due to improvement of healthcondition.

To estimate the learning curve for laparoscopic liver resections performed by a surgeon experienced in robot-assisted liver resections using the CUSUM method. Materials and methods. The study involved a retrospective analysis of the results of laparoscopic liver resections for malignant and benign neoplasms performed from 2015 to December 2020 and robot-assisted liver resections from 2010 to 2020. The author evaluated the learning curve for laparoscopic liver resections of a surgeon who had mastered robot-assisted resections of high difficulty. Selecting the boundaries between training periods according to the obtained CUSUM graphs was determined by critical changes in the resection difficulty score (IWATE and IMM), duration of surgery, blood loss, and incidence of postoperative complications. Major perioperative events were compared between the laparoscopic and robot-assisted resection groups in each of the training periods. Results. 174 laparoscopic and 57 robot-assisted liver resections were performed. The duration of the first training period comprised 11 robot-assisted resections and 20 laparoscopic resections, the second period – 16 and 20, the third period – 30 and 134, accordingly. In the second period, the resection difficulty score increased significantly for both groups, while the amount of blood loss, the incidence of postoperative complications, and the duration of hospital treatment did not differ significantly. In the second training period, the duration of surgery was significantly longer in both groups. Conclusion. Studying the dynamics of surgical difficulty using the CUSUM method is considered to be a reliable, controlled way to estimate the learning curve for liver resection. Completing the learning curve for robot-assisted liver resections reduces the duration of the learning curve for laparoscopic resections compared to published data of other authors.","PeriodicalId":505469,"journal":{"name":"Annaly khirurgicheskoy gepatologii = Annals of HPB Surgery","volume":" 67","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results. Radical removal of the major papilla adenoma was performed in 90.5 % of cases. 16.6 % of cases revealed complications as follows: postmanipulation pancreatitis in 10 (7.9 %) cases, bleeding in 7 (5.5 %), and duodenal perforation in 4 (3.1 %). 1–3 year follow-up period revealed residual adenomatous overgrowths in 9.5 % of cases. An endoscopic classification of major papilla adenomas was developed, thereby leading to a decrease in thecomplication and re-intervention rates. The classification enables the character of intraductal spread of adenomas to be specified and indications for their endoscopic excision to be determined. Conclusion. The developed endoscopic classification of major duodenal papilla adenomas contributes to selection of the most effective and safe method of surgical intervention. An application of the classification implies unification of an endoscopic description of the tumor and consistency in patient monitoring by different specialists.","PeriodicalId":505469,"journal":{"name":"Annaly khirurgicheskoy gepatologii = Annals of HPB Surgery","volume":" 16","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the efficacy of various methods of intraductal contact lithotripsy in “complex” choledocholithiasis. Materials and methods. From January 2018 to July 2023, 40 patients underwent intraductal contact lithotripsy with oral transpapillary cholangioscopy. Indications for the procedure included failure of mechanical lithotripsy in large choledocholithiasis in 37 patients (92.5 %), impaction of the gallstone during conventional lithoextraction, narrow pancreatic part of common bile duct, intrahepatic localization of gallstones. Contact electrohydraulic lithotripsy was performed in 10 patients (25 %), laser fragmentation by holmium laser in 15 patients (37.5 %), and new thuliumlaser – in 15 patients (37.5 %). Results. The overall efficacy of contact lithotripsy methods comprised 90%. Laser methods demonstrated comparable results: the overall success rate of lithotripsy with holmium laser accounted for 93.3 %, and with thulium laser – 90 %. Complete sanitation after the first intervention with holmium lithotripsy was achieved in 92.9 % of patients, with thulium laser – in 88.9 %. The efficacy of electrohydraulic lithotripsy was lower: the overall success rate comprised86.7 %, and the success rate after the first procedure accounted for 61.5 % of patients. The average number of interventions required to achieve complete sanitation of the bile ducts amounted to 1.07 for holmium laser lithotripsy,1.1 for thulium laser, and 1.6 for electrohydraulic lithotripsy. In 1 case (2.5 %), perforation of the wall of the common bile duct was noted during the extraction of stone fragments. The complication was corrected during retrograde intervention.

To summarize data, define indications and estimate outcomes of cholangioscopy performed by various accesses to the bile ducts. Materials and methods. In the period of 2017–2024, 68 cholangioscopies were performed in 24 (35.3 %) men and 44 (64.7 %) women. The age of patients ranged from 18 to 85 years (mean age comprises 61 years). 10 (14.7 %) cholangioscopies were performed by retrograde access, 42 (61.8 %) by antegrade access, and 16 (23.5 %) were performed intraoperatively. Results. The total amount of interventions include 21 (30.9 %) lithoextractions, 16 (23.5 %) targeted biopsies, 12 (17.6 %) recanalizations of anastomosis strictures, and 1 (1.79 %) case involved a retrieval of the “lost” bile duct stent. In 7 (10.3 %) cases cholangioscopy failed due to a small diameter of the bile ducts. Conclusion. Contemporary minimally invasive endoscopic methods considerably enlarge the possibilities for treatment of complex lesions of the bile ducts. Antegrade cholangioscopy contributes to a wider application of modern technologies for direct examination of the bile ducts and to expansion of the range of therapeutic manipulations. The introduction of antegrade cholangioscopy avoids extensive traumatic reconstructive interventions with their potential risk of complications.","PeriodicalId":505469,"journal":{"name":"Annaly khirurgicheskoy gepatologii = Annals of HPB Surgery","volume":" 41","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140392208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
