ObjectiveTo investigate the safety and efficacy of transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy （EHL）. MethodsA retrospective analysis was performed for the clinical data of 60 patients with large common bile duct stones who were admitted to Department of Gastroenterology， Jilin People’s Hospital， from May 1， 2023 to January 31， 2026， and according to the treatment method， the patients were divided into transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group and peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group， with 30 patients in each group. The two groups were compared in terms of the rate of successful single-session stone fragmentation and removal， procedural time， duration of electrohydraulic lithotripsy， clinical success rate， and complications. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group， the transparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy group had a significantly higher technical success rate （83.33% vs 60.00%， χ²=4.022， P=0.045） and significantly shorter procedural time ［46.00 （42.25 — 49.00） min vs 54.50 （42.00 — 65.00） min， Z=2.012， P=0.044］ and duration of electrohydraulic lithotripsy ［8.00 （6.25 — 11.75） min vs 13.50 （9.25 — 17.75） min， Z=2.749， P=0.006］. Both groups achieved a clinical success rate of 100%， with no significant difference in the incidence rate of complications （P>0.05）. ConclusionTransparent cap-assisted peroral cholangiopancreatoscopy-guided electrohydraulic lithotripsy has a high rate of successful single-session stone fragmentation and removal and a short procedural time， with good safety and efficacy， and therefore， it holds promise for clinical application.

ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To evaluate the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) combined with peroral cholangioscopy in the treatment of gallbladder stones with common bile duct stones.Methods:Clinical data of 19 patients with gallbladder stones and common bile duct stones admitted to the Digestive Endoscopy Center, Jilin People’s Hospital from July 2019 to November 2024 were retrospectively analyzed, including 13 males and 6 females, aged (68.2±14.2) years. All patients underwent ERCP combined with peroral cholangioscopy. Perioperative data, including the long diameter of the common bile duct stone, the long diameter of the gallbladder stone, the number of stones, ERCP operative time, gallbladder stone extraction time, stone clearance status, hospitalization duration, and complications, were recorded. Postoperative follow-up was conducted through outpatient visits or telephone consultations to monitor recurrence.Results:The long diameter of the common bile duct stones was (9.55±2.86) mm, and the long diameter of the gallbladder stones was 4.0(3.0, 5.5) mm. Among the 19 patients, 5 had single gallbladder stones, and 14 had multiple stones. The ERCP operative time was (49.0±18.4) min, and the gallbladder stone extraction time was (25.0±11.7) min. The methods used for handling the gallbladder neck were as follows: two cases involved stone removal after 6 mm balloon dilation; six cases involved stone removal after metal stent placement; three cases involved the placement of a plastic stent in the gallbladder for three months, followed by stone extraction using ERCP combined with peroral cholangioscopy; eight cases were treated directly for stone removal without specific procedures. Among the 19 patients, 11 completed stone removal within one treatment, while eight required a second treatment. All patients had complete clearance of both common bile duct and gallbladder stones under direct peroral cholangioscopy. No severe complications occurred postoperatively, although two cases developed post-ERCP pancreatitis. The postoperative hospitalization time was 8.0 (6.0, 10.0) d. The follow-up duration for the 19 patients was 14.0 (8.5, 20.0) months. One patient had a recurrence of gallbladder stones 12 months postoperatively, while no other patients had recurrence at the final follow-up.Conclusion:ERCP combined with peroral cholangioscopy is a safe and feasible approach for treating gallbladder stones with common bile duct stones.

ObjectiveTo discuss the effects of Cistanches Herba phenylethanoid glycosides （CHPhGs） on the intestinal mucosal barrier and gut microbiota in alcoholic liver disease （ALD） mice were discussed. MethodThe 36 C57BL/6N female mice were randomly divided normal group， normal group of CHPhGs， model group， and low， medium， and high-dose groups （175， 350， 700 mg·kg^-1） of CHPhGs， with six mice in each group. The ALD mouse model was built using Lieber-Decarli alcohol liquid feed. The normal group and low， medium， and high-dose groups of CHPhGs were given CHPhGs by gavage daily. Serum aspartate aminotransferase aminotransferase （ALT）， alanine aminotransferase （AST）， triglycerides （TG）， and total cholesterol （TC） levels were detected by an automatic biochemical analyzer. Serum tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， lipopolysaccharide （LPS）， lipopolysaccharide-binding protein （LBP）， D-lactic acid （D-LA）， diamine oxidase （DAO）， and LBP of liver were detected by enzyme-linked immunosorbent assay （ELISA）. The levels of TG and TC in the liver were detected by colorimetry. Liver tissue was treated by oil red O and hematoxylin-eosin （HE） staining. The microstructure of jejunum epithelial cells was observed by electron microscope. Jejunum and colon were treated by HE staining and alcian blue-periodate-scheff (AB-PAS) staining staining， and mucin 2 （Muc2） was treated by immunohistochemistry. The intestinal contents of the normal group， normal group of CHPhGs， model group， and high-dose group of CHPhGs were collected and sequenced. ResultThe ALD model was established successfully. Compared with the normal group， the levels of serum ALT， AST， and TG， as well as the levels of liver TG and TC in the model group were significantly increased （P<0.05）. Histopathology showed that compared with the normal group， the liver cells in the model group showed obvious steatosis. Compared with the model group， the levels of serum TG and liver TG and TC in the low， medium， and high-dose groups of CHPhGs decreased significantly （P<0.05）. The serum ALT， AST， TNF-α， IL-1β， LPS， and LBP in the high-dose group of CHPhGs were also significantly decreased （P<0.05）. The number of liver cells with steatosis in the high-dose group of CHPhGs was significantly reduced， and the microvilli structure of jejunum epithelial cells was basically intact. The expression of Muc2 was reduced in the colon， and the gut microbiota of the high-dose group of CHPhGs changed significantly （P<0.05）. Compared with the normal group， the Allobaculum was significantly up-regulated in the model group （P<0.05）. Compared with the model group， the abundance of Akkermansia in the high-dose group of CHPhGs was significantly increased （P<0.01）. The abundance of Akkermansia was negatively correlated with that of Allobaculum （r=-0.701， P<0.01）. ConclusionCHPhGs can reduce the intestinal barrier injury caused by ALD， which may play a protective role by regulating the abundance and structure of Akkermansia and Allobaculum and affecting the homeostasis of intestinal mucus.

ObjectiveTo investigate the safety and efficacy of endoscopic retrograde cholangiopancreatography （ERCP） combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in the treatment of difficult choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 12 patients with difficult choledocholithiasis who underwent ERCP and electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in Department of Gastroenterology， Jilin People’s Hospital， from May to November 2022. The clinical effect of lithotripsy and lithotomy was observed， and postoperative complications and time of surgical operation were assessed. ResultsAmong the 12 patients， 11 （91.67%） were successfully treated by electrohydraulic lithotripsy under direct view， 9 （75.00%） achieved first-attempt success in lithotripsy， and 11 （91.67%） had complete removal of calculi； 1 patient was found to have stenosis of the bile ducts caused by multiple biliary tract surgeries， and grade Ⅱ intrahepatic bile duct stones above the sites of stenosis were removed under direct view， but there were still residues of grade Ⅲ intrahepatic bile duct stones， which led to the fact that complete calculus removal was not achieved. The mean time of ERCP operation was 91.3±26.2 minutes， including a time of 41.8±22.2 minutes for energy lithotripsy. There were 2 cases of postoperative biliary tract infection which were improved after anti-infective therapy， 2 cases of hyperamylasemia which were not given special treatment， and 3 cases of mild pancreatitis which were improved after symptomatic medication， and there were no complications such as bleeding and perforation. ConclusionERCP combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system is safe， effective， and feasible in the treatment of difficult choledocholithiasis.
