Abstract Objective: In 2015, the Asociación Colombiana de Gastroenterología (Colombian Association of Gastroenterology), with the support of the Institute of Clinical Research of the Universidad Nacional de Colombia, created the Clinical Practice Guideline for the diagnosis and treatment of ulcerative colitis. Since then, new therapeutic alternatives and concepts about treatment goals have emerged, making it necessary to update its contents. Materials and methods: The present update was carried out by a multidisciplinary team with support from the Asociación Colombiana de Gastroenterología and the Clinical Research Institute of the Universidad Nacional de Colombia. Questions regarding new treatments and endoscopic surveillance of adult patients with ulcerative colitis were developed, and national and international guidelines were searched in specialized databases. The guidelines were evaluated in terms of quality and applicability. The Cochrane Group conducted a systematic search of the existing literature, and evidence tables and recommendations were made using the GRADE methodology. Results: The guideline for the treatment of ulcerative colitis in adults in Colombia was updated, and new treatment algorithms were designed, taking into account the extent and activity of the disease and the different levels of care. Conclusions: The relevance of clinical and endoscopic assessment for treatment was established, and the indications for the proper management of patients with ulcerative colitis were specified. Furthermore, recommendations were made for endoscopic surveillance of colorectal cancer, and the importance of chromoendoscopy was established.

Surveillance study of irrigating fluid absorption and bleeding in transurethral resection of the prostate / 中华泌尿外科杂志

Objective To investigate the effect of the endoscopic surveillance system in irrigating fluid absorption and bleeding during transurethral resection of the prostate.Methods In vitro trials,we simulated the fluid absorption and bleeding in the operation by using self-developed endoscopic surveillance system from January 2013 to June 2013.Continuous irrigation of 5 ％ mannitol solution,we extracted 5 times irrigating fluid (each time 100 ml and a total of 500 ml) in the process of irrigation and recorded absorption measurements of every time extraction rinses.At the same time,we dripped human whole blood 5 times(each time 5 ml and a total of 25 ml) in the process of irrigation and recorded the bleeding measurements.The above process was repeated three times to detect the accuracy and consistency of the endoscopic surveillance system.In clinical trials,50 cases of BPH were monitored in surgery and the biochemical index,hemodynamics,irrigating fluid absorption and bleeding were compared from October 2016 to April 2017.The included criteria contained as follow:the age of patients should be more than 50 years.The transabdominal ultrasound showed that the volume of prostate should be more than 60 ml.The maximal uroflowmetry should be less than 15ml/s.The IPSS scores should be more than 8.Based on the operative time,two groups (＜60 min and ≥ 60 min) were classified.Results We developed the endoscopic surveillance system which is original in the world.In vitro trials,the average irrigating fluid were (100.60 ± 2.07) ml,(201.00±3.39) ml,(302.00±4.67) ml,(403.60±4.39) ml and (502.40 ±7.57) ml;and the average bleeding were (5.06 ± 0.11) ml,(10.10 ± 0.16) ml,(15.04 ± 0.15) ml,(20.06 ± 0.11) ml and (25.10 ± 0.16) ml.No significant difference was observed in all groups (P ＞ 0.05).In clinical trials,we compared some preoperative and postoperative indexes.The average blood oxygen saturation were (94.46 ± 2.49) ％ and (92.39 ± 2.77) ％ (P ＜ 0.01),the average Serum sodium ion concentration were (141.05 ± 2.52) mmol/L and (138.06 ± 4.27) mmol/L(P ＜ 0.01),the average HGB were (143.50 ± 13.43) g/L and (137.04 ± 14.25) g/L(P ＜ 0.01).The average HCT were (42.05 ± 4.09) ％ and (137.04 ± 14.25) ％ (P ＜ 0.01).The average HR were (77.9 ± 7.6) beats per minute and (77.93 ± 6.93) beats per minute (P＞0.05).The MAP were (90.32 ± 9.75) mmHg and (91.07±8.96)mmHg(P＞0.05).The average serum potassium ion concentration were (4.13 ± 0.53) mmol/L and (4.09 ± 0.37) mmol/L (P ＞ 0.05).The average irrigating fluid absorption of the group less than 60 minutes and the group equal or more than 60 minutes were (401.83 ± 279.23) ml and (885.25 ± 367.68) ml (P ＜ 0.01).The average blood loss were (64.10 ±47.47) ml and (158.40 ± 65.22) ml(P ＜0.01).The preoperative and postoperative hemodynamic,blood biochemical and hematology showed difference in our trials.Irrigating fluid absorption and blood loss were positively associated with operation time.Conclusions The endoscopic surveillance system was safety and accuracy.It can offer real-time monitoring data and alarm mechanism for the surgeons that possibly improve operation safety.

The Use of the Prague Classification System in the Reporting of Barrett’s Surveillance Endoscopies.

Aims: The Prague classification for the reporting of Barrett’s oesophagus has been validated in previous studies and is recommended by the British Society of Gastroenterologists (BSG) in their latest guidelines. In this short study we aim to audit the adherence to the use of this system in endoscopy reports produced in a busy teaching hospital in the UK. Methods: We retrospectively audited all the reports for endoscopies performed as surveillance for patients with known Barrett’s oesophagus within a six month period. These reports were examined as to whether or not the Prague classification system was employed. Results: Sixty-seven reports were inspected and six were excluded as Barrett’s was not seen. Twenty-six of the 61 reports studied (43%) used the Prague classification system. The remainder used descriptions and length measurements felt appropriate by the endoscopist. Conclusions: The BSG guidelines emphasise the importance of measuring Barrett’s using a standard methodology. The rationale for this include aiding communication, increasing the level of diagnostic confidence and providing an estimate of the risk of adenocarcinoma development based on segment length. The use of the Prague classification is validated, explicit and consensus driven. However our study demonstrates that only 43% of endoscopy reports use the Prague system. The reason for this lack of adherence is unclear and may benefit from further study.

Timing and diagnostic value of endoscopic biopsy of intestinal graft after small bowel transplantation / 中华器官移植杂志

Objective To summarize the timing and diagnostic value of endoscopic biopsy of intestinal graft after small bowel transplantation (SBTx).Methods Fifteen cases of SBTx were divided into 3 eras:era Ⅰ (1994-1995)-3 cases of SBTx treated with cyclosporine-based immunosuppression; era Ⅱ (2003-2006)-7 cases of SBTx treated with tacrolimus-based immunosuppression,and era Ⅲ (2007-present) than CVC group 5 cases of SBTx treated with Atemtuzumab induction therapy and maintenance tacrolimus monotherapy.The scheme of endoscopic surveillance was initially used in era Ⅲ, the first endoscopic biopsy was performed on postoperative day 3,2 times weekly during the first month, followed once weekly during months 2-3, once every other week during months 4-6 and once monthly thereafter.When clinical signs and symptoms of rejection were present, and during rejection episodes, the additional endoscopic biopsies were also performed.Results A total of 276 biopsies of these 15 SBTx recipients were obtained.Fifty-one biopsies (18.5%) were diagnosed as acute cellular rejection (ACR), which included IND to mild (n = 32,11.6 %), moderate (n = 9,3.3 %), and severe (n = 1 0, 3.6 %), two biopsies (0.7 %) were diagnosed as cytomegalovirus (CMV) enteritis and other 2 biopsies (0.7 %) bacteria enteritis.The ACR episodes verified by biopsy pathology and undergoing anti-rejection treatment were 20 (11 IND to mild,5 moderate,and 4 severe) ,and 1 episode of CMV enteritis and 1 episode of bacteria enteritis were observed.Conclusion Endoscopic surveillance and biopsy pathology is crucial diagnostic tool for ACR and sepsis.ACR surveillance after SBTx and early diagnosis of ACR could be made with scheming endoscopic biopsies.Endoscopic biopsy can be used to make differential diagnosis when clinical signs and symptoms were present, and to guide the treatment during anti-rejection episode.
