Radiation proctopathy, which can be categorized as acute and chronic, is defined as the radiation damage to the rectum caused by radiation therapy in patients with pelvic malignancies. Chronic radiation proctopathy can cause complications such as rectal bleeding, which severely affects patients’ quality of life. At present, endoscopic therapy has become the primary method for diagnosis and treatment of bleeding from chronic radiation proctopathy. In October 2019, the American Society for Gastrointestinal Endoscopy (ASGE) published "ASGE guideline on the role of endoscopy for bleeding from chronic radiation". The guideline described the effectiveness and safety of different endoscopic therapies such as argon plasma coagulation, bipolar electrocoagulation, heater probe, radiofrequency ablation, cryoablation, etc. in the treatment of bleeding from chronic radiation. This paper interprets it to provide references for clinicians in the treatment of bleeding from chronic radiation.
Objective To investigate whether intraductal electrocautery incision （IEI） could decrease the recurrence of post-liver transplant anastomotic strictures （PTAS） after conventional endoscopic intervention of balloon dilatation （BD） and plastic stenting （PS）. Methods The clinical data of 27 patients with PTAS who were given endoscopic treatment of BD＋PS or IEI＋BD＋PS in our hospital from January 2007 to October 2011 were reviewed retrospectively. Results The treatment of BD＋PS was initially successful in 9 of 11 （81.8%） cases， but showed recurrence in 5 of 9 （55.6%）. The treatment of IEI＋BD＋PS was initially successful in 14 of 16 （87.5%） cases, and the recurrence was observed only in 3 of 14 （21.4%）. The total diameter of inserted plastic stents in IEI＋BD＋PS group was significantly greater than that in BD＋PS group 〔（12±3.2） Fr vs. （8±1.3） Fr，P=0.039〕. All recurrences were successfully retreated by IEI＋BD＋PS. Procedure-related complications included pancreatitis in 5 cases （18.5%）, cholangitis in 8 cases （29.6%）, bleeding after EST in 1 cases （3.7%）, which were all cured with medical treatment. No complications related to intraductal endocautery incision procedure such as bleeding and perforation were observed. Median follow-up after completion of endoscopic therapy was 22 months （range 1-49 months）. Conclusions Intraductal electrocautery incision is an effective and safe supplement to balloon dilatation and plastic stenting treatment of PTAS, which can decrease the recurrence of anastomotic strictures in conventional endoscopic intervention.
ObjectiveTo understand advances in the timing and surgical mode selection of gastrointestinal endoscopy and surgical intervention for acute biliary pancreatitis (ABP).MethodThe recent literatures on the timing and choice of gastrointestinal endoscopy and surgical treatments aimed at ABP were reviewed.ResultsFor ABP patients with early cholangitis or biliary obstruction, no matter how serious, endoscopic treatment should be used to relieve obstruction and relieve symptoms. For patients only with ABP, if non-surgical treatment was not effective and patients showed symptoms such as biliary obstruction or biliary tract infection, endoscopic intervention should be considered. Most ABP patients had milder symptoms and could undergo cholecystectomy during the same hospitalization to prevent ABP recurrence after symptoms relief. Patients with severe ABP could be treated with cholecystectomy along with pancreatic necrotic tissue removal, and surgery should be performed after the disease was controlled. If the preoperative imaging examination highly suspected that there were stones in the biliary tract, biliary exploration should be performed at the same time. Laparoscopic surgery should be selected as far as possible to facilitate the postoperative recovery of the patient.ConclusionsFor patients with ABP, whether endoscopic or surgical treatment, the timing and surgical mode selection should follow the specific clinical situation with the “individualization” principle of the treatment. We should make the reasonable and effective policy at diagnosis and treatment according to different conditions.
ObjectiveTo explore the safety and effectiveness of endoscopic treatment for biliary tract complications after liver transplantation.MethodsPatients who underwent endoscopic treatment for biliary tract complications after liver transplantation from January 2009 to December 2018 in West China Hospital were enrolled. Characteristics of patients, types of biliary tract complications, effectiveness of endoscopic treatment and endoscopic related complications were collected and analyzed.ResultsAmong the 57 patients with biliary tract complications, 37 patients had biliary stricture alone, 4 patients had bile leak alone, 15 patients had biliary stricture plus biliary stones or sludge, and 1 patient had biliary stricture combined with biliary leakage. A total of 112 treatments of endoscopic retrograde cholangiopancreatography (ERCP) were performed, among which 100 treatments were accomplished successfully (89.3%), including the improvement of bile duct stenosis, the cure of bile leak and the successful removal of common bile duct stones. The number of total ERCP related complications was 15 (13.4%), among which post ERCP pancreatitis was the most common (9.8%).ConclusionEndoscopic therapy can be considered as an initial treatment for biliary tract complications after liver transplantation as its safety and effectiveness.
Objective To evaluate the efficacy and safety of traditional Chinese medicine (TCM) in treating Chronic Rhinosinusitis (CRS) after Functional Endoscopic Sinus Surgery (FESS). Methods The following databases and periodicals such as PubMed (Jan. 1980 to Jan. 2009), MEDLINE (1980 to 2009), EBSCOhost (Jan. 1975 to Jan. 2009), CALIS (1984 to 2009), CNKI (1979 to 2007), VIP (1989 to 2009), CBM (1978 to 2009); Chinese Journal of Otorhinolaryngology Head and Neck Surgery (1990 to 2008), Journal of Clinical Otorhinolaryngology Head and Neck Surgery (1988 to 2008), Otorhinolaryngology Head and Neck Surgery (1990 to 2008), and Chinese Journal of Otorhinolaryngology of Integrated Traditional and Western Medicine (1996 to 2008) were searched by computer and handwork for randomized controlled trials (RCTs) about TCM to treat CRS after ESS. The trial screening, quality assessment, and the data extraction of the included trials were conducted before performing statistical analyses by using RevMan 4.2.10 software. Results A total of 32 RCTs in three sub-groups in Chinese literatures were identified with meta-analyses in comparisons of the cure rate (OR=1.99, 95%CI 1.78 to 2.23), total effective rate (OR=2.66, 95%CI 2.20 to 3.22), degree I postoperative improvement rate (OR=2.22, 95%CI 1.60 to 3.06), total postoperative improvement rate (OR=8.77, 95%CI 1.09 to 70.64), postoperative clean time (OR=2.54, 95%CI 1.70 to 3.79), postoperative epithelization time (OR= –29.46, 95%CI –37.73 to –21.18), and mucociliary transport rate (OR=1.14, 95%CI 0.22 to 2.06). A total of 4 RCTs were meta-analyzed to evaluate the safety in comparisons of gastrointestinal reaction (OR=0.25, 95%CI 0.00 to 33.78) and local reaction (OR=0.03, 95%CI 0.01 to 0.12). Conclusion The current evidence shows TCM in treating CRS after ESS tends to improve the clinical efficacy and reduce the cure time without obvious adverse reaction. Due to the low methodological quality of included trials, more RCTs with high quality and large scale are required.

Objective To evaluate the therapeutic effects of endoscopic treatment on biliary tract complications after liver transplantation. Methods The clinical data of 55 patients with biliary tract complications after liver transplantation undergoing endoscopic treatment from January 2006 to June 2009 were analyzed retrospectively. Results Ninety-eight times of endoscopic treatment were performed in 55 patients. There were 11 cases of biliary fistula, 4 cases of bile duct stricture with biliary fistula, 21 cases of bile duct stricture, 12 cases of bile duct stricture with biliary sludge or stones, 3 cases of biliary sludge or stones, 2 cases of angular distortion of the bile duct and papilla duodeni stenosis in 2 cases. Different procedures including biliary tract dilation, endoscopic nasobiliary drainage, endoscopic sphincterotomy, stone extraction technique and biliary stent placement were performed in different biliary tract complications. The endoscopic treatments were successful in 46 cases (83.6%). The procedure related complications were found in 13 times (13.3%). Conclusion Endoscopy may serve as the primary modality for treating biliary tract complications after liver transplantation with safety and effectiveness.
