Does the "Endoscopic Surgical Skill Qualification System" Reduce Serious Intraoperative Complications in the Field of Pediatric Surgery?

Background: The Japanese endoscopic surgical skill qualification system (ESSQS) in pediatric surgery was started 10 years ago to encourage safe and appropriate pediatric minimally invasive procedures and avoid severe complications. The present study investigated the impact of the ESSQS on the incidence of serious complications in the field of pediatric endoscopic surgery. Materials and Methods: We sent a questionnaire to institutes belonging to the Japanese Pediatric Endoscopic Surgery Group. Institutes were divided into two groups: institutes with (Group A) or without (Group B) ESSQS-qualified pediatric surgeons at any point in the last 10 years. Intraoperative complications (grade 3 and 4 under the Classification of Intraoperative Complications [CLASSIC] classification), postoperative complications (grade ≥IIIb under the Clavien/Dindo classification), and the number and rate of endoscopic procedures and complications of advanced and common procedures were compared between the two groups. This study is an exempt survey since no patient identifier has been collected. Results: We collected answers from 46 of 102 institutes (response rate: 45%) (Group A: 18 institutes, Group B: 28 institutes). Intra/postoperative complications were significantly more frequent in Group A than in Group B (P = .02 and P < .001, respectively). Endoscopic operations accounted for a larger proportion of advanced and common surgeries in Group A than in Group B, and the rate of postoperative complications of advanced procedures was significantly higher in Group A than in Group B (P = .012). Conclusion: While endoscopic surgery was performed more frequently in Group A than in Group B, the incidence of intra/postoperative serious complications was significantly higher in Group A. The current Japanese ESSQS was unable to markedly reduce the rate of serious complications.

Colonoscopy-Related Mortality in a Fecal Immunochemical Test–Based Colorectal Cancer Screening Program

Many countries have introduced colorectal cancer (CRC) screening programs with fecal immunochemical tests (FITs), and follow-up colonoscopies for individuals with a positive FIT result. In order to make an informed decision to participate, individuals must be informed about the benefits and harms of FIT-based screening and subsequent colonoscopy. Colonoscopy-related fatal complications in FIT-based screening are understudied. We aimed to estimate the colonoscopy-related mortality in a national FIT-based CRC screening program. Colonoscopy-related mortality within 30 days after colonoscopy was assessed by analysis of data from national endoscopy complication databases in the Netherlands, determining the excess 30-day rate of death in FIT-positive individuals undergoing colonoscopy vs FIT-negative individuals (based on data from the national screening database), and determining the rate of likely colonoscopy-related deaths based on registered causes of death by the Statistics Netherlands. Between October 2013 and December 2017, 172,797 participants underwent colonoscopy after a positive result from a FIT in the Dutch national CRC screening program; 13,848 participants received a diagnosis of CRC. The reported fatal complication rate was 0.23 per 10,000 FIT-positive participants (or 1 per 43,199; 95% CI, 0.090 - 0.60) undergoing colonoscopy, whereas this was 0.91 per 10,000 FIT-positive participants (or 1 per 10,961; 95% CI, 0.44 - 1.38) according to the excess death rate. Likely colonoscopy-related causes of death were reported in 0.86 per 10,000 FIT-positive participants (or 1 per 11,236; 95% CI, 0.48 - 1.63) who underwent colonoscopy, of which 50% considered cardiovascular events. Colonoscopy-related mortality within the Dutch FIT-based CRC screening program was estimated to range from 0.23 to 0.91 per 10,000 FIT-positive participants undergoing colonoscopy. These findings indicate underreporting of fatal complications in registries and a noteworthy incidence of fatal cardiovascular adverse events that requires further investigation. Nevertheless, the harm of FIT-based CRC screening is vastly outweighed by the benefits.

Mo1745 ENDOSCOPIC SUBMUCOSAL DISSECTION IN IBD ASSOCIATED DYSPLASIA: A SYSTEMATIC REVIEW

Guidelines for management of IBD associated dyplasia are evolving but 2015 consensus guidelines recommend surveillance over colectomy for patients with complete endoscopic removal of dysplastic lesions. 2019 guidelines from the American college of gastroenterology also support complete endoscopic removal of dysplastic lesions as an alternative to colectomy. Critically, confirmation of complete removal can be challenging with lesions that are large or fibrotic requiring piecemeal resection. Endoscopic submucosal dissection offers improved rates of en-bloc resection compared to endoscopic mucosal resection and may be the optimal technique for resection of large or fibrotic IBD-associated dysplastic lesions. An electronic search of EMBASE (1974–present), MEDLINE (1946–present), EBM Reviews– Cochrane Central Register of Controlled Trials (1946–present), EBM Reviews–Cochrane Database of Systematic Reviews (2005–present), and Google Scholar was conducted for studies reporting outcomes of endoscopic resection of large dysplastic lesions in IBD. Bibliographies of retrieved articles were also reviewed for relevant publications. Outcomes were extracted and pooled for comparison across techniques. Two tailed p-values were calculated using fishers exact test. 195 articles were identified on initial search. 154 were excluded based on review of title. 41 papers were reviewed in full. Case-reports, review articles and consensus statements were excluded. 8 individual case series and cohort studies were identified. In total, 295 unique patients and 322 unique lesions were identified. 122 (41%) patients were male, 95% had ulcerative colitis, 4% Crohn’s and 1% were undifferentiated. 166 lesions were removed by EMR, 116 via ESD and 30 using hybrid techniques. 10 lesions were managed with colectomy. A significantly higher proportion of lesions excised by ESD compared to EMR/hybrid were fibrotic (91.5% vs 7.7%, p<.00001) and non-polypoid (82% vs 60%, p<.008). Lesion size was not consistently reported and could not be pooled. Endoscopic recurrence did not differ between ESD and EMR/hybrid (8.6% vs 4.6%, p<.219). ESD had a significantly higher en-bloc resection rate (92% vs 78%, p<.005). Overall complication rates did not differ significantly (ESD 6% vs EMR 2% p<.097, ESD 6% vs hybrid 6.6% p<1). Published reports of endoscopic resection and specifically ESD for IBD associated dysplasia show favourable outcomes as measured by complete resection, low recurrence and acceptable complication rates. ESD has higher en-bloc resection rates compared to EMR, with no significant difference in endoscopic recurrence or complications. Interpretation of comparisons between EMR and ESD is likely biased by tendency to use ESD for flatter and more fibrotic lesions.

Gastrointestinal Polyps and Polyposis in Children: Experience of Endoscopic and Surgical Outcomes

Introduction: There are gaps in the literature regarding outcome of multiple polyps and dilemmas in the management issues in polyposis syndromes in children. Objective: We aimed to study the clinical behaviour of gastrointestinal (GI) polyps with emphasis on therapeutic outcomes of polyposis syndrome. Methods: Proven cases of GI polyp(s) on endoscopy were classified as single polyp, multiple polyps, and polyposis syndrome. Complex presentation was defined as 1 or more of the following: severe anaemia, anasarca, intussusception, rectal mucosal prolapse, and diarrhoea. A clinico-endoscopic criterion was applied in polyposis syndrome patients for the decision of surgery versus endoscopic therapy with surveillance. Results: Of total 240 patients, there were no significant differences between single (52.5%, n = 126) versus multiple polyps (27.5%, n = 66) with respect to age, symptoms, histology, and recurrence. Polyposis syndrome (20%, n = 48) presented with complex symptoms (50%), higher family history, significantly lower haemoglobin, total protein, and albumin as compared to single and multiple polyps (p < 0.01). Nineteen polyposis patients with favourable clinico-endoscopic criteria were endoscopically eradicated for polyps in 3 (1–4) sessions with sustenance of laboratory parameters at 1 year and 30% symptomatic recurrence at follow-up of 23.5 (7–40) months. There were no major endoscopic complications. Nineteen patients required proctocolectomy with improvement in laboratory parameters 6 months post-surgery. Conclusions: Multiple polyps behave similar to single polyps in children. A clinico-endoscopic criterion may guide for optimal management of polyposis syndrome. Colectomy may be effectively deferred in a large proportion of polyposis syndrome patients if maintained on an endoscopic protocol.

Endoscopic Yield, Appropriateness, and Complications of Pediatric Upper Gastrointestinal Endoscopy in an Adult Suite: A Retrospective Study of 822 Children.

Background/AimsThis study aimed to study the endoscopic yield, appropriateness, and complications of pediatric endoscopy performed by adult gastroenterologists in an adult endoscopic suite. MethodsThis a retrospective study in which records of all the patients less than 18 years of age who underwent endoscopy in the last 5 years were studied. The indications of endoscopy in children were categorized as appropriate or inappropriate per the latest guidelines by American Society for Gastrointestinal Endoscopy and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. Positive endoscopic yield was defined as the presence of any abnormality on endoscopy. ResultsAmong the total of 822 children (age <18 years), the most common indications were variceal surveillance/eradication in 157 (19.1%), followed by dyspepsia in 143 (17.4%), upper gastrointestinal (UGI) bleeding in 136 (16.5%), recurrent abdominal pain in 94 (11.4%), unexplained anemia in 74 (9%), recurrent vomiting in 50 (6.08%), chronic refractory gastroesophageal reflux disease in 34 (4.1%) and others; 780 out of 822 endoscopic procedures (94.9%) done in children were appropriate as per the guidelines. The endoscopic yield was 45.8%, highest in patients with UGI bleeding (71.3%), followed by variceal surveillance (54.8%), recurrent vomiting (38%), dyspepsia (37.8%), and recurrent abdominal pain (36%). Minor adverse events occurred in 7.3% of children. ConclusionsPediatric endoscopy performed by an experienced adult gastroenterologist may be acceptable if done in cooperation with a pediatrician.

Radiologic Assessment for Endoscopic US-guided Biliary Drainage.

Endoscopic US-guided biliary drainage (BD) is performed for various types of biliary obstruction and is mainly indicated for unsuccessful conventional transpapillary endoscopic retrograde cholangiodrainage. In endoscopic US BD, an extra-anatomic drainage route between the gastrointestinal (GI) tract and the biliary system is created with a covered metallic stent or plastic stent. Procedural types of endoscopic US BD include hepaticogastrostomy, hepaticojejunostomy (after gastrectomy), choledochoduodenostomy, hepaticoduodenostomy, and endoscopic US-guided gallbladder drainage. The technical and clinical success rates of endoscopic US BD are reported to be 94%-97% and 88%-100%, respectively. CT is crucial both in preprocedural assessment and postprocedural monitoring. CT is used to determine the indications for endoscopic US BD, which include the type of biliary obstruction, collateral vessels in the puncture route, ascites, the volume of the liver segment, the distribution of an intrahepatic tumor, and GI tract patency. After endoscopic US BD, common subclinical findings are a small amount of intraperitoneal gas, localized edematous change in the GI tract, a notch in the placed stent, and localized biliary dilatation caused by stent placement. Stent malfunction after endoscopic US BD is caused by impaction of debris and/or food, stent migration into the GI tract, or tumor overgrowth and/or hyperplasia. Complications that can occur include internal stent migration, intraperitoneal biloma, arterial bleeding or pseudoaneurysm, perforation of the GI tract, and portobiliary fistula. The incidence of clinical endoscopic US BD-related complications is 11%-23%. ©RSNA, 2020.

VISUAL AND ANATOMIC OUTCOMES OF PEDIATRIC ENDOSCOPIC VITRECTOMY IN 326 CASES

To report on the indications, outcomes, and complications of endoscopic vitrectomy in a large cohort of pediatric vitreoretinal patients. This is a retrospective interventional case series consisting of 244 eyes of 211 patients aged 18 years or younger undergoing a total of 326 endoscopic vitrectomies from 2008 to 2017. A 23-gauge vitrectomy was performed with use of a 19-gauge endoscope. Two hundred and eleven patients with a mean age of 7.5 years (range: 0-18 years) and median follow-up since last surgery of 28 months (range: 3 months-8.7 years) were included. The most common indication for endoscopic vitrectomy was retinal detachment (234/326; 72%) with proliferative vitreoretinopathy (162/234; 69%). Other diagnoses included trauma (25%), retinopathy of prematurity (15%), and glaucoma (9%). Twenty-five percent of surgeries (80/326) were performed on eyes with significant corneal opacities. Retinal reattachment was achieved in 67% of eyes with retinal detachment (119/178). Visual acuity improved in 26% of retinal detachment eyes versus 53% of nonretinal detachment eyes (P = 0.005). Surgical complications included band keratopathy (15%), hypotony (8%), cataract (7%), and elevated intraocular pressure (3%). In this large series of pediatric endoscopic vitreoretinal surgeries, anatomic outcomes and complication rates were comparable with previous studies.

Effect of hospital teaching status on endoscopic retrograde cholangiopancreatography mortality and complications in the USA.

Our aim was to assess the differences in outcomes of cholecystitis, pancreatitis, gastrointestinal (GI) bleed, GI perforation, and mortality in teaching versus nonteaching hospitals nationwide among therapeutic and diagnostic ERCPs. We hypothesized that complication rates would be higher in teaching hospitals given greater patient complexity. Inpatient diagnostic and therapeutic ERCPs were identified from the National Inpatient Sample (NIS) from 2008 to 2012. The presence of ACGME-approved residency programs is required to qualify as a teaching hospital. Nonteaching urban and rural hospitals were grouped together. We identified hospital stays complicated by pancreatitis, cholecystitis, GI hemorrhage, perforation, and mortality. Logistic regression propensity-matched analysis was performed in SPSS to compare differences in complication rates between teaching and nonteaching hospitals. A total of 1,466,356 weighted cases of inpatient ERCPs were included in this study: of those, 367 and188 were diagnostic, 1,099,168 were therapeutic, 766,230 were at teaching hospitals, and 700,126 were at nonteaching hospitals. Mortality rates were higher in teaching hospitals when compared to nonteaching hospitals for diagnostic (OR 1.266, p < 0.001) and therapeutic ERCPs (OR 1.157, p = 0.001). There was no significant difference in rates of post-ERCP cholecystitis, pancreatitis, or perforation between the two groups. Among diagnostic ERCPs, GI hemorrhage was higher in teaching compared to nonteaching hospitals (OR 1.181, p = 0.003). Likewise, length of stay was increased in teaching hospitals (7.9 vs 6.9days, p < 0.001, for diagnostic and 6.5 vs 5.8days, p < 0.001, for therapeutic ERCPs). In conclusion, teaching hospitals were noted to have a higher mortality rate associated with inpatient ERCPs as well as higher rates of GI hemorrhage in diagnostic ERCPs, which may be due to a higher comorbidity index in those patients admitted to teaching hospitals.

General principles for the prevention and treatment of complications of percutaneous endoscopic gastrostomy (review of literature)

We considered the views of researchers presented in the modern literature on both the problem as a whole and discussion questions regarding the causes of development, preventive measures, and methods of treating percutaneous endoscopic gastrostomy complications, such as clogging of the gastrostomy tube, peristomal wound infections, necrotic fasciitis, pneumoperitoneum, buried bumper syndrome, growth of granulations in the gastrostomy zone, postoperative bleeding and intraparietal hematoma of the gastric wall, traumatic dislocation of the gastrostomy tube, peritonitis after percutaneous endoscopic gastrostomy, peristomal leakage, сolonic fistula, liver injury and abdominal wall metastasis at the percutaneous endoscopic gastrostomy site.

Endoscopic Removal of Foreign Body in Upper Gastrointestinal Tract in Dogs: Success Rate and Complications

Background: Dogs and cats with acute signs of choking, retching, cough, vomiting, regurgitation, hypersalivation, dysphagia and odynophagia should have the presence of a gastrointestinal foreign body (FB) as part of their differential diagnosis, where it is a frequent condition in the care of small animals. Most objects lodged in the esophagus, stomach, and proximal duodenum can be removed by upper digestive endoscopy, a curative, little invasive procedure. The objective of our study was to evaluate the physical aspects and location of esophageal and gastric FBs observed in 88 dogs and the age and breed of the affected animals and to determine the success rate and eventual complications associated with the procedure as well.Materials, Methods &amp; Results: Eighty-eight cases of dogs, males and females of varying ages and breeds, submitted to upper digestive endoscopy were selected because of suspicion of esophageal or gastric FBs. The endoscopic procedure aimed at confirming the diagnosis, whether or not followed by endoscopic removal of these objects. Prior to endoscopy, the animals had laboratory tests (blood count and serum biochemistry) and subsequently to the anesthetic protocols of choice for each case. Data including breed, age, type of constituent material and anatomical location of the FB, endoscopic procedure success rate and complications were recorded and descriptively evaluated. Of the 88 dogs evaluated, 60% (n = 53) were male and 40% (n = 35) female. According to the breed of the animals, 55% (n = 49) were small-breed dogs, 29% (n = 25) large-breed dogs, and 8% (n = 7) medium-breed dogs, and 8% were of mixed breed dogs, which could assume various sizes. Shih Tzus accounted for 18% (n = 16) of the animals, Lhasa apsos 8% (n = 7) and mixed breed 8% (n = 7), where these were the most frequently affected breeds. Regarding age, animals 1 to 5 years old represented 66% (n = 58) of the patients, and those 6 to 10 years old accounted for 20% (n = 18), while 11% of the dogs were over 10 years old (n = 10). Two animals (3%) had no information about their ages. Pieces of cloth were the most frequently found FBs, representing 20%(n = 20), followed by animal bones (19%) and fruit pits (10%). As for location, 78% (n = 69) of the FBs were located in the stomach and 22% (n = 19) in the esophagus. The success rate of endoscopic FB removal in this study was 83% (n = 73). In 76% (n = 67) of the animals, there were no complications due to the presence of FB in the upper gastrointestinal tract. The most frequent complications were esophageal ulcerations (n = 7) and the inability to move the FB (n = 5) and adherences. (n = 4).Discussion: The results showed that small-breed dogs, especially Shih Tzus and Yorkshires, represented a larger number of cases, probably due to their popularity in Brazil, where the study was conducted. Males were more prevalent than females, and the most affected age was between 1 and 5 years, with emphasis on younger animals. There were more gastric FB cases compared to esophageal FB cases, which was related to the interval between the ingestion of the object and veterinary care. Although not the most prevalent FB, the high rate of mango pits can be explained by the vast number of mango trees in the Federal District. There were few complications compared to the success of cases, indicating that endoscopy is the procedure of choice for the diagnosis and removal of FBs from the gastrointestinal tract.

DOP23 Endoscopic evaluation at 1 month after ileocolic resection for Crohn’s disease predicts postoperative recurrence and is safe

Abstract Background Endoscopic surveillance remains the gold standard for evaluating postoperative recurrence in Crohn’ disease (CD). However, the optimal timing of the first postoperative endoscopic evaluation is unclear. The commonly used strategy, first endoscopy at 3, 6, or 12 months, demonstrates high rates of endoscopic recurrence, which means this strategy may delay the detection and treatment. The aim of this study was to determine the clinical value and safety of the endoscopy at 1 month after surgery, and define the related factors. Methods This was a prospective cohort study of CD patients undergoing an ileocolic resection between 2015 and 2018, with a postoperative colonoscopy at 4–5 week after surgery. The primary outcome was endoscopic recurrence at 12 months, or clinical recurrence, or surgical recurrence within 12 months after surgery. Univariate and multivariate analyses were performed to identify related factors. Results Eighty-four eligible CD patients were included. Among 84 colonoscopies at 4–5 week, no endoscopic complication occurred. The main endoscopic findings at the first evaluation were anastomotic ulcers (45 [10 circumferential ulcers and 35 scattered ulcers], 53.6%), ulcers in the neoterminal ileum (16, 19.0%), oedema in anastomosis (50, 59.5%), mild narrowing in anastomosis (7, 8.3%), and mild narrowing in neoterminal ileum (3, 3.6%). On univariate and multivariable analysis, anastomotic scattered ulcers were associated with forward postoperative recurrence (HR, 2.532; 95% CI, 1.019–6.318; p = 0.046). We then used the modified Rutgeerts score to define endoscopic findings: i0, 26(44.0%); i1, 4(4.8%); i2a (circumferential anastomotic ulcers were not included), 40(34.5%); i2b, 11(13.1%); i3, 0; i4, 3(7.1%). Univariate and multivariable analysis showed ≥i2a were associated with forward postoperative recurrence (HR, 3.174; 95% CI, 1.218–8.273; p = 0.018). No factor was associated with ≥i2a at the first endoscopy. Conclusion Endoscopic evaluation at 4–5 weeks after surgery in CD was safe, and endoscopic findings were associated with postoperative recurrence. Earlier endoscopic examination after surgery may be useful for the adjustment of medication.

Percutaneous Endoscopic Gastrostomy After Cardiothoracic Surgery in Children Less Than 2 Months Old: An Assessment of Long-Term Malnutrition Status and Gastrostomy Outcomes.

Infants with critical congenital heart disease undergoing cardiothoracic surgery commonly experience chronic malnutrition and growth failure. We sought to determine whether placement of a percutaneous endoscopic gastrostomy was associated with reduced moderate-severe malnutrition status and to describe percutaneous endoscopic gastrostomy-related clinical and safety outcomes in this population. Single-center, retrospective cohort study. Two hundred fifty-nine-bed, tertiary care, pediatric referral center. Children with congenital heart disease less than 2 months old undergoing cardiothoracic surgery from 2007 to 2013 with and without percutaneous endoscopic gastrostomy. None. Primary outcomes were weight for age z scores during hospitalization, at 6 months, and 1 year after cardiothoracic surgery. Secondary outcomes were frequency of percutaneous endoscopic gastrostomy revision, percutaneous endoscopic gastrostomy complications, and mortality. Statistical analyses included Wilcoxon rank-sum, Fisher exact, and Student t tests. Two hundred twenty-two subjects met study criteria, and 77 (35%) had percutaneous endoscopic gastrostomy placed at a mean of 45 ± 31 days after cardiothoracic surgery. No differences were noted for demographics, comorbidities, and weight for age z score at birth and at the time of cardiothoracic surgery. The percutaneous endoscopic gastrostomy cohort had greater Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery risk category (4 [4-5] vs 4 [2-4]) and length of stay (71 d [49-101 d] vs 26 d [15-42 d]). Mean weight for age z score at the time of percutaneous endoscopic gastrostomy was -2.8 ± 1.3. Frequency of moderate-severe malnutrition (weight for age z score, ≤ -2) was greater in children with percutaneous endoscopic gastrostomy at discharge (78% vs 48%), 6 months (61% vs 16%), and 1 year (41% vs 2%). Index mortality was lower in children with percutaneous endoscopic gastrostomy at 30 days (8% vs 0%) and hospital discharge (19% vs 4%). However, no mortality differences were observed after discharge. Growth velocity after percutaneous endoscopic gastrostomy was greater (44 ± 19 vs 10 ± 9 g/d). Children tolerated percutaneous endoscopic gastrostomy without hemodynamic compromise, minor percutaneous endoscopic gastrostomy complications, and anticipated percutaneous endoscopic gastrostomy revisions. Children without mortality had percutaneous endoscopic gastrostomy removal at a median duration of 253 days (133-545 d). Children with univentricular physiology had improved in-hospital mean growth velocity (6.3 vs 24.4 g/d; p < 0.01) and reduced 1-year rate moderate-severe malnutrition (66.7% vs 36.9%; p < 0.01) after percutaneous endoscopic gastrostomy placement. Percutaneous endoscopic gastrostomy placement was well tolerated and associated with improved postoperative growth velocity in children with critical congenital heart disease undergoing cardiothoracic surgery less than 2 months old. These findings were also noted in our subanalysis of children with univentricular physiology. Persistent rates of moderate-severe malnutrition were noted at 1-year follow-up. Although potential index mortality benefit was observed, definitive data are still needed.

Nursing empowerment by simulation in percutaneous endoscopic gastrostomy short-time complication control: Protocol study.

BACKGROUND:Percutaneous endoscopic gastrostomy (PEG) is one of the most suitable methods for long-term nutritional support. In this study, the empowerment of intensive care nurses is examined by a simulation technique to control the short-term complications of PEG.METHODS:A two-group clinical trial study will be conducted on eighty intensive care nurses in a teaching hospital in Tehran. The study participants will be randomly assigned to one of the two control and intervention groups based on the inclusion criteria. A pretest will be given to both groups using a researcher-made tool. Then, the empowerment package developed by the researcher will be provided to the intervention group in two stages. Next, a posttest will be administered. After this stage, patients’ complications with PEG will be observed using a researcher-made checklist. Nurses’ performances in both control and intervention groups will be evaluated in terms of preventing and controlling short-term complications up to 1 week after PEG insertion. All of the data collected in this research will be analyzed with statistic tests such as independent t-test, standard deviation, T pair, ANOVA, and mean based on the SPSS 16 software.RESULTS:At present, the research team is designing an empowerment package for nurses and tools needed to evaluate the nurses’ empowerment.CONCLUSION:This study will attempt to design and evaluate the empowerment package of graduate nurses with a cognitive empowerment approach and using a simulation technique to care for patients with PEG and to control their short-term complications.

Management of Post Endoscopic Retrograde Cholangio-Pancreatography (ERCP) Duodenal Perforation, Experience of a University Hospital

Background: Duodenal perforation is an uncommon complication of endoscopic retrograde cholangio- pancreatography (ERCP). Most cases are minor perforations that can be managed with conservative management. A few cases may result in life-threatening retroperitoneal collection and necrosis requiring surgical intervention. There is a relative paucity of references specifically describing the surgical interventions required for this eventuality. Methods: Ten cases of post-ERCP duodenal perforation were referred to our department at Ain Shams university Hospital between 2015 and 2019. Clinical features of our cases were analyzed, and the management plan was tailored to each case after discussion in multidisciplinary team (MDT) and review of the latest available literatures. Results: Seven patients recovered with conservative management. Three patients needed surgical intervention. All patients were successfully discharged home. There were no mortalities. Conclusions: Post-ERCP duodenal perforation is an uncommon complication of endoscopy, but when it does occur, it is potentially life-threatening. Early diagnosis may lead to a better outcome through early intervention. Most cases need only conservative treatment. A variety of surgical techniques may need to be employed according to the individual circumstances of the case.

Evaluation of endoscopic retrograde cholangiopancreatography success and complications according to age

Giriş ve Amaç: Endoskopik retrograd kolanjiopankreatografi diğer gastrointestinal endoskopik yöntemlere göre daha yüksek komplikasyon oranına sahiptir. Özellikle komplikasyon geliştiğinde, yaşlı hastaların operasyonlar sonrası düzelmesi gençlere göre daha zor olmaktadır. Bu çalışmada amacımız çeşitli yaş gruplarında yapılan endoskopik retrograd kolanjiopankreatografi işlemlerinin değerlendirilmesi ve yaşlı hastalarda işlem başarısı ve güvenilirliğinin değerlendirilmesidir. Gereç ve Yöntem: Kliniğimizde Ocak 2018-Haziran 2018 tarihleri arasında yapılan 301 hastaya ait endoskopik retrograd kolanjiopankreatografi işlemleri retrospektif olarak değerlendirildi. Hastalar yaşlarına göre 60 yaş altı, 60-80 yaş arası ve 80 yaş üstü olarak 3 gruba ayrıldı. Her grupta işlem başarısı, komplikasyonlar, işlem tekrarı gerekliliği, işlem endikasyonları değerlendirildi ve gruplar birbiriyle karşılaştırıldı. Bulgular: Hastaların 163’ü (%54.2) kadın ve 138’i (%45.8) erkekti. Tüm hasta gruplarında en sık endoskopik retrograd kolanjiopankreatografi endikasyonu safra taşıydı. İşlem başarısı, işlem tekrarı gerekliliği, pre-cut kesi gerekliği açısından gruplar arası fark saptanmadı. Grup 2 ve 3’de endoskopik retrograd kolanjiopankreatografi endikasyonları benzer iken Grup 1’de Grup 2 ve Grup 3’e göre benign nedenler anlamlı olarak daha fazla saptandı. Komplikasyonlar değerlendirildiğinde gruplar arasında istatiktiksel olarak anlamlı fark saptanmadı (p=0.837). Hastaların hiçbirinde perforasyon, kanama ya da ölüm görülmedi. Sonuç: Çalışmamızda endoskopik retrograd kolanjiopankreatografi başarısı, işlem tekrarı gerekliliği ve komplikasyonları tüm yaş gruplarında benzer saptadık. Çalışmamız ve literatür eşliğinde yaşlılarda endoskopik retrograd kolanjiopankreatografi işleminin gençler ile benzer etkinlik ve güvenlikte olduğunu düşünmekteyiz.

Endoscopic Retrograde Cholangiopancreatography-Related Complications and Their Management Strategies: A "Scoping" Literature Review.

Endoscopic retrograde cholangiopancreatography (ERCP) is a well-known procedure with both diagnostic and therapeutic utilities in managing pancreaticobiliary conditions. With the advancements of endoscopic techniques, ERCP has become a relatively safe and effective procedure. However, as ERCP is increasingly being utilized for different advanced techniques, newer complications have been noticed. Post-ERCP complications are known, and mostly include pancreatitis, infection, hemorrhage, and perforation. The risks of these complications vary depending on several factors, such as patient selection, endoscopist's skills, and the difficulties involved during the procedure. This review discusses post-ERCP complications and management strategies with new and evolving concepts.

Safety of endoscopic retrograde cholangiopancreatography in liver transplanted patients: A single‐center retrospective study

AbstractThe incidence rate of endoscopic retrograde cholangiopancreatography complication in liver transplanted patient has not been well studied. Some studies believed such patients inherit higher complication risk in ERCP procedure owing to innate structure deformity and coagulopathy condition. Our aim of this study is to evaluate the post‐ERCP complications incidence in liver transplanted patients. All liver transplant patients (deceased donor and living‐related donor) from January 2010 to December 2015 who underwent ERCP procedure alone in Changhua Christian medical center hospital were retrospective evaluated. Data regarding post‐ERCP complications, including pancreatitis, hemorrhage, perforation, and infection, are collected and analyzed. A total of 98 ERCP procedures were performed in 43 liver transplanted patients during 5‐year period. The overall incidence rate of post ERCP complications was 13.27%. The most common complication was bleeding 6.12%, followed by pancreatitis 5.10%, perforation 2.04%, and cholangitis 1.02%. Among patients with post‐ERCP hemorrhage, more than half of the patients had delay bleeding and required more than two times of endoscopic procedure. Differ from general ERCP complications, all of the perforation events were related to bile duct injury.

107 The Prevalence of Endoscopic Retrograde Cholangiopancreatography-Related Complications in Patients With Liver Transplant: A Meta-Analysis and Systematic Review

INTRODUCTION: Biliary complications following liver transplantation are usually managed with endoscopic retrograde cholangiopancreatography (ERCP); however, the literature on post-ERCP complications remains poorly reported and largely inconsistent in this patient population. Hereby we aimed to systematically review and analyze the literature on complication rates associated with the performance of ERCP in patients with liver transplant. METHODS: We performed a comprehensive literature search in PubMed, PubMed Central, Embase, and ScienceDirect databases from inception through May 2019 to identify all the studies that evaluated post-ERCP complications in patients with liver transplant. Effect estimates from the individual studies were extracted and combined using the random effect, generic inverse variance method of DerSimonian and Laird, and a pooled odds ratio (OR) and prevalence were calculated. Forest plots were generated, and publication bias was assessed for using conventional techniques. RESULTS: Fourteen studies with a total of 1787 patients were included in this analysis. In total, 3192 ERCPs were performed on these patients. The pooled all-complication rate was 5.2% (95% CI: 0.035–0.075) (Figure 1). Procedural complications analyzed included post-ERCP pancreatitis 3.4% (95% CI: 0.025–0.047), bleeding 1.1% (95% CI: 0.006–0.020), infections 0.2% (95% CI: 0.025–0.047), and cholangitis 0.8% (95% CI 0.004–0.020) (Figure 2a–d). No cases of periprocedural death were reported. The pooled OR for post-ERCP pancreatitis in patients with liver transplant compared to patients without liver transplant was 1.289 (95% CI: 0.455–3.653, P = 0.633, I2 = 72.88%) (Figure 3). CONCLUSION: The risk of post-ERCP complications has been a major concern for many endoscopists in patients with liver transplantation. This might be related to theoretical concerns of distorted anatomy and difficult cannulation, combined with a general lack of evidence on the true prevalence of these complications. Our study confirms that post-ERCP complication rates are comparable to the general population undergoing ERCP and hence, peri-procedural evaluation and management should be continued as per the standard of care in this patient population.

2150 Successful Endoscopic Closure of a Pyeloduodenal Fistula Using the Over-the-Scope Clip System

INTRODUCTION: Approximately 100 cases of pyeloduodenal fistula (PDF) have been reported in the literature. PDF most often results from pyelonephritis due to nephrolithiasis, when inflammation extends to the duodenum given its relative immobility and lack of posterior peritoneal covering. Diagnosis of a PDF is usually made with computed tomography (CT) of the abdomen with contrast. The mainstay of therapy for PDF is nephrectomy and primary closure of the duodenum. We are presenting the second documented case of endoscopic closure of a PDF using the over-the-scope clip (OTSC) system and the third case of endoscopically treated PDF. This method provides an alternative to open surgery. CASE DESCRIPTION/METHODS: A 62 year old female presented with sharp, severe abdominal pain. She denied back pain, hematuria, fever, and dysuria. She had no significant past medical history and did not take any medications. CT abdomen and pelvis demonstrated a large right-sided staghorn calculus extending into the renal pelvis. The patient underwent percutaneous nephrolithotomy, which was complicated by perforation of the renal pelvis and abdominal compartment syndrome. Subsequently, a proximal ureteral stricture was refractory to stenting and balloon dilation. CT urography demonstrated a PDF (Image 1). After placement of a metallic ureteral stent and nephrostomy tube, a nephrostogram was negative for extravasation, so the patient underwent EGD to evaluate for the resolution of the PDF. During the procedure, iohexol contrast and methylene blue were inserted via nephrostomy tube, and fluoroscopic imaging showed contrast in the right kidney and bladder without extravasation. However, on endoscopy, methylene blue extravasation led to identification of two mucosal defects in the anterior duodenal sweep (Image 2). The larger defect was closed using the helix tissue retractor and OTSC system (12/6 t-type) (Image 3). The smaller defect was closed with 2 hemostasis clips. Follow-up renal scan and CT imaging showed no evidence of contrast extravasation. DISCUSSION: The OTSC is an innovative endoscopic technique most often used for hemostasis and for treatment of endoscopic or surgical complications (e.g., fistula, leakage, or perforation). Most reports document successful OTSC use for fistula closure including gastrocutaneous and esophageal fistulas. Our case is, to our knowledge, the second ever documented PDF closure using the OTSC system.
