Double-Blind Multicenter Randomized Clinical Trial Comparing Glucagon vs Placebo in the Resolution of Alimentary Esophageal Impaction.

INTRODUCTION: The aim of this study was to compare the effectiveness of glucagon vs placebo in resolving esophageal foreign body impaction (EFBI), as well as the length of the procedure and adverse events. METHODS: This was a multicenter, randomized, double-blind trial involving consecutive patients diagnosed with alimentary EFBI. Participants were randomized to receive either 1 mg of intravenous glucagon or placebo. All patients underwent upper endoscopy, and adverse events were assessed through a protocolized telephonic interview 7 days later. RESULTS: The study included 72 subjects in the glucagon group and 68 in the placebo group. The foreign body was not identified in 23.6% of subjects in the glucagon group and 20.6% of subjects in the placebo group (difference 3%, 95% confidence interval -10.7% to 16.8%, P = 0.67). The median time required to remove the foreign body was similar in both groups 4 minutes (range 2-10) in the glucagon group and 3.5 minutes (range 2-7) in the placebo group (difference 0.5 minutes, 95% confidence interval -1.3 to 2.3; P = 0.59). The most common adverse event reported in both groups was mild pharyngeal pain. DISCUSSION: Glucagon is no more effective than placebo in resolving EFBI or shortening the time required to remove the foreign body (EUDRA-CT number 2019-004920-40).

Antimigration versus conventional fully covered metal stents in the endoscopic treatment of anastomotic biliary strictures after deceased-donor liver transplantation.

INTRODUCTION: Migration of fully covered metal stents (FCMS) remains a limitation of the endoscopic treatment of anastomotic biliary strictures (ABS) following orthotopic liver transplantation (OLT). The use of antimigration FCMS (A-FCMS) might enhance endoscopic treatment outcomes for ABS. METHODS: Single center retrospective study. Consecutive patients with ABS following OLT who underwent ERCP with FCMS placement between January 2005 and December 2020 were eligible. Subjects were grouped into conventional-FCMS (C-FCMS) and A-FCMS. The primary outcome was stent migration rates. Secondary outcomes were stricture resolution, adverse event, and recurrence rates. RESULTS: A total of 102 (40 C-FCMS; 62 A-FCMS) patients were included. Stent migration was identified at the first revision in 24 C-FCMS patients (63.2%) and in 21 A-FCMS patients (36.2%) (p = 0.01). The overall migration rate, including the first and subsequent endoscopic revisions, was 65.8% in C-FCMS and 37.3% in A-FCMS (p = 0.006). The stricture resolution rate at the first endoscopic revision was similar in both groups (60.0 vs 61.3%, p = 0.87). Final stricture resolution was achieved in 95 patients (93.1%), with no difference across groups (92.5 vs 93.5%; p = 0.84). Adverse events were identified in 13 patients (12.1%) with no difference across groups. At a median follow-up of 52 (IQR: 19-85.5) months after stricture resolution, 25 patients (24.5%) developed recurrences, with no difference across groups (C-FCMS 30% vs A-FCMS 21%; p = 0.28). CONCLUSIONS: The use of A-FCMS during ERCP for ABS following OLT results in significantly lower stent migration rates compared to C-FCMS. However, the clinical benefit of reduced stent migration is unclear. Larger studies focusing on stricture resolution and recurrence rates are needed.

Prospective cohort study to evaluate premedication with simethicone and n-acetilcysteine for upper diagnostic gastrointestinal endoscopy.

INTRODUCTION: The use of premedication for upper gastrointestinal endoscopy (UGE) is not widely established in western countries. The primary aim of the study was to compare gastric visibility according to the total visibility score (TVS). The secondary aim was to assess complications, diagnostic yield, endoscopic procedure time, sedation dose and patient satisfaction. METHODS: A single center prospective cohort study was performed of consecutive adults undergoing an UGE in the afternoon working shift. After completing enrolment in the control group, patients were administered 200 mg simethicone and 500 mg N-acetylcysteine diluted in 100 ml of water >15 minutes before the procedure. All procedures were recorded and a single, blinded endoscopist evaluated the TVS after recruitment of both cohorts. Patient satisfaction was evaluated using the Spanish translation of the American Society of Gastrointestinal Endoscopy satisfaction questionnaire. RESULTS: 205 patients were included in the study, 103 females (50.2%) with a median age of 54.8-years (IQR: 41.2-65.2). 104 were enrolled to the control group and 101 to the intervention group. Patients receiving premedication presented a higher rate of adequate (74.3% vs 45.2; difference 95% CI: 16,3-41,9%, p<0.001) and excellent gastric visibility (23.8% vs 7.7%; difference 95% CI: 6,3-25,8%, p=0.002). Propofol dose was similar, although the median procedure time was lower in the group of no intervention [5 (IQR: 4-7) vs 6 minutes (IQR: 5-7); p=0.03]. Procedure related adverse events were similar, except that patient without premedication experienced more nausea episodes. Major and minor endoscopic findings and the satisfaction questionnaire showed no differences between both groups. CONCLUSION: Patients receiving premedication with simethicone and N-acetylcysteine had a better gastric visibility score, without any increase in adverse events or affecting the patients' satisfaction.

Invasive Streptococcus suis isolated in Spain contain a highly promiscuous and dynamic resistome.

Introduction: Streptococcus suis is a major pathogen for swine and human. Here we aimed to know the rates of antimicrobial resistance (AMR) in invasive S. suis isolates recovered along Spain between 2016 - 2021 and elucidate their genetic origin. Methods: Antibiotic susceptibility testing was performed for 116 isolates of different genetic backgrounds and geographic origins against 18 antibiotics of 9 families. The association between AMR and genotypes and the origin of the isolates were statistically analyzed using Pearson´s chi-square test and the likelihood ratio. The antimicrobial resistant genes were identified by whole genome sequencing analysis and PCR screenings. Results: High AMR rates (>80%) were detected for tetracyclines, spectinomycin, lincosamides, and marbofloxacin, medium (20-40%) for sulphonamides/trimethoprim, tiamulin, penicillin G, and enrofloxacin, and low (< 20%) for florfenicol, and four additional ß-lactams. The occurrence of multidrug resistance was observed in 90% of isolates. For certain antibiotics (penicillin G, enrofloxacin, marbofloxacin, tilmicosin, and erythromycin), AMR was significantly associated with particular sequence types (STs), geographic regions, age of pigs, and time course. Whole genome sequencing comparisons and PCR screenings identified 23 AMR genes, of which 19 were previously reported in S. suis (aph(3')-IIIa, sat4, aadE, spw, aac(6')-Ie-aph(2'')-Ia, fexA, optrA, erm(B), mef(A/E), mrs(D), mph(C), lnu(B), lsa(E), vga(F), tet(M), tet(O), tet(O/W/32/O), tet(W)), and 4 were novel (aph(2'')-IIIa, apmA, erm(47), tet(T)). These AMR genes explained the AMR to spectinomycin, macrolides, lincosamides, tiamulin, and tetracyclines. Several genes were located on mobile genetic elements which showed a variable organization and composition. As AMR gene homologs were identified in many human and animal pathogens, the resistome of S. suis has a different phylogenetic origin. Moreover, AMR to penicillin G, fluoroquinolones, and trimethoprim related to mutations in genes coding for target enzymes (pbp1a, pbp2b, pbp2x, mraY, gyrA, parC, and dhfr). Bioinformatic analysis estimated traits of recombination on target genes, also indicative of gene transfer events. Conclusions: Our work evidences that S. suis is a major contributor to AMR dissemination across veterinary and human pathogens. Therefore, control of AMR in S. suis should be considered from a One Health approach in regions with high pig production to properly tackle the issue of antimicrobial drug resistance.

Mutations in SCNM1 cause orofaciodigital syndrome due to minor intron splicing defects affecting primary cilia.

Orofaciodigital syndrome (OFD) is a genetically heterogeneous ciliopathy characterized by anomalies of the oral cavity, face, and digits. We describe individuals with OFD from three unrelated families having bi-allelic loss-of-function variants in SCNM1 as the cause of their condition. SCNM1 encodes a protein recently shown to be a component of the human minor spliceosome. However, so far the effect of loss of SCNM1 function on human cells had not been assessed. Using a comparative transcriptome analysis between fibroblasts derived from an OFD-affected individual harboring SCNM1 mutations and control fibroblasts, we identified a set of genes with defective minor intron (U12) processing in the fibroblasts of the affected subject. These results were reproduced in SCNM1 knockout hTERT RPE-1 (RPE-1) cells engineered by CRISPR-Cas9-mediated editing and in SCNM1 siRNA-treated RPE-1 cultures. Notably, expression of TMEM107 and FAM92A encoding primary cilia and basal body proteins, respectively, and that of DERL2, ZC3H8, and C17orf75, were severely reduced in SCNM1-deficient cells. Primary fibroblasts containing SCNM1 mutations, as well as SCNM1 knockout and SCNM1 knockdown RPE-1 cells, were also found with abnormally elongated cilia. Conversely, cilia length and expression of SCNM1-regulated genes were restored in SCNM1-deficient fibroblasts following reintroduction of SCNM1 via retroviral delivery. Additionally, functional analysis in SCNM1-retrotransduced fibroblasts showed that SCNM1 is a positive mediator of Hedgehog (Hh) signaling. Our findings demonstrate that defective U12 intron splicing can lead to a typical ciliopathy such as OFD and reveal that primary cilia length and Hh signaling are regulated by the minor spliceosome through SCNM1 activity.

Efficacy and safety of cold versus hot snare polypectomy for small (5-9 mm) colorectal polyps: a multicenter randomized controlled trial.

BACKGROUND: Resection techniques for small polyps include cold snare polypectomy (CSP) and hot snare polypectomy (HSP). This study compared CSP and HSP in 5-9 mm polyps in terms of complete resection and adverse events. METHODS: This was a multicenter, randomized trial conducted in seven Spanish centers between February and November 2019. Patients with ≥ 1 5-9 mm polyp were randomized to CSP or HSP, regardless of morphology or pit pattern. After polypectomy, two marginal biopsies were submitted to a pathologist who was blinded to polyp histology. Complete resection was defined as normal mucosa or burn artifacts in the biopsies. Abdominal pain was only assessed in patients without < 5 mm or > 9 mm polyps. RESULTS: 496 patients were randomized: 237 (394 polyps) to CSP and 259 (397 polyps) to HSP. Complete polypectomy rates were 92.5 % with CSP and 94.0 % with HSP (difference 1.5 %, 95 % confidence interval -1.9 % to 4.9 %). Intraprocedural bleeding occurred during three CSPs (0.8 %) and seven HSPs (1.8 %) (P = 0.34). One lesion per group (0.4 %) presented delayed hemorrhage. Post-colonoscopy abdominal pain presented similarly in both groups 1 hour after the procedure (CSP 18.8 % vs. HSP 18.4 %) but was higher in the HSP group after 5 hours (5.9 % vs. 16.5 %; P = 0.02). A higher proportion of patients were asymptomatic 24 hours after CSP than after HSP (97 % vs. 86.4 %; P = 0.01). CONCLUSIONS: We observed no differences in complete resection and bleeding rates between CSP and HSP. CSP reduced the intensity and duration of post-colonoscopy abdominal pain.

Combined endoscopic retrograde and endosonography-guided (CERES) cholangiography for interventional repair of transected bile ducts after cholecystectomy: treatment approaches and outcomes.

BACKGROUND: Post-cholecystectomy transected bile ducts (TBDs) are not amenable to standard endoscopic management. Combined ERCP and endosonography (CERES) including EUS-guided hepaticoenterostomy enhance therapeutic biliary endoscopy. CERES treatment of post-cholecystectomy TBDs is evaluated. METHODS: Among 165 consecutive patients who underwent ERCP for post-cholecystectomy bile duct injury (Amsterdam A/B/C/D grades [%] = 47/30/7/16) between January 2009-November 2020 at a tertiary-care center, 10/26 (38%) with TBDs (6 female; 32-92 years old) underwent CERES before attempted endoscopic repair (staged CERES, n = 7) or surgical repair (preoperative CERES, n = 1), or as destination therapy (definitive CERES, n = 2). Short-term clinical success rate, final clinical success rate and comprehensive complication index (CCI) were retrospectively determined. Additionally, number of follow-up procedures, adverse events, recurrences, final patency grades and definitive cure rate were determined in patients with staged CERES. RESULTS: Index CERES (hepaticogastrostomy, 60%; hepaticoduodenostomy, 40%) achieved bile leak and jaundice resolution in 10 patients (100% short-term clinical success rate). Overall, 9/10 patients maintained good/excellent biliary drainage over a median 3.2 years without any unplanned percutaneous/surgical procedures (90% final clinical success rate; median CCI = 8.7). Staged CERES using recanalization (n = 6) or diversion (n = 1) strategies achieved Grade A patency in 5/7 (71%) patients after a median of 2 follow-up procedures over a median 12-month treatment period; 2 failed recanalization patients were salvaged by indefinite hepaticoenterostomy stent or elective surgery, respectively. Among staged CERES, 2 treatment-related cholangitis occurred (29%) and 2 recurring strictures (29%) developed over a median 8.4 year follow-up; recurring strictures were endoscopically remodeled (n = 1) or indefinitely stented (n = 1); final Grade A/B biliary patency was achieved in 5/7 (71%) and definitive cure in 4/7 (57%). CONCLUSIONS: CERES controls acute symptoms in selected post-cholecystectomy TBD patients allowing subsequent staged endoscopic therapy. Definitive cure or long-term biliary drainage is possible in most cases and elective surgery can be facilitated in the remainder.

Reply to: "Does it matter which plastic stents we use for the treatment of post-surgical leaks? Or is it a one-size-fits-all?"

We appreciate the interest of Sánchez-Luna et al. in our article "Endoscopic internal drainage using transmural double-pigtail stents in leaks following upper gastrointestinal tract surgery", and find their suggestion about using softer urological double pigtail stents (DPS) for endoscopic internal drainage (EID) interesting.

An algorithm selection methodology for automated focusing in optical microscopy.

Autofocus systems are essential in optical microscopy. These systems typically sweep the sample through the focal range and apply an algorithm to determine the contrast value of each image, where the highest value indicates the optimal focus position. As the optimal algorithm may vary according to the images' content, we evaluate the 15 most used algorithms in the field using 150 stacks of images from four different kinds of tissue. We use four measuring criteria and two types of analysis and propose a general methodology to apply to select the best fitting algorithm for any given application. In this paper, we present the results of this evaluation and a detailed discussion of different features: the threshold used for the algorithms, the criteria parameters, the analysis used, the bit depth of the images, their magnification, and the type of tissue, reaching the conclusion that some of these parameters are more relevant to the study than others, and the implementation of the proposed methodology can lead to a fast and reliable autofocus system capable of performing an analysis and selection of algorithms with no supervision required.

Endoscopic ultrasound-guided fine-needle biopsy in patients with unexplained diffuse gastrointestinal wall thickening.

Background and study aims Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is recommended after non-diagnostic biopsy in gastrointestinal wall thickening, although the performance of currently available FNB needles in this setting is unknown. We aimed to assess the diagnostic accuracy and safety of EUS-FNB and to evaluate the "T" wall staging in malignant pathology. Patients and methods This was a single center retrospective study that included all consecutive patients undergoing EUS-FNB for diffuse gastrointestinal wall thickening with at least one previous negative conventional endoscopic biopsy between January 2016 and November 2019. EUS-FNB was performed using linear-array echoendoscopes with slow-pull/fanning technique. Tissue acquisition was done with 19- or 22-gauge biopsy needles. Samples were included in formalin without rapid on-site evaluation and submitted for histopathological processing. The final diagnosis was based on conclusive histology or absence of evidence of disease progression after follow-up at least 6 months. Results Twenty-nine patients (21 men), with a median age of 68 (IQR: 56-77), were included. EUS-FNB was technically feasible and the sample quality was adequate for full histological assessment in all patients (100 %). Sensitivity, specificity, positive and negative predictive values, and overall accuracy for diagnosis of malignancy were 95.5 %, 100 %, 100 %, 83.3 %, and 96.3 %, respectively. In patients with malignant disease, the samples obtained allowed detection of signs of deep layer infiltration ("histological staging") in 17 of 21 cases (81 %). No adverse events were noted. Conclusions The EUS-FNB technique demonstrated excellent diagnostic performance and safety in the study of unexplained diffuse gastrointestinal wall thickening. Histological staging was obtained in a high percentage of samples.

The role of endoscopic ultrasound guidance for biliary and pancreatic duct access and drainage to overcome the limitations of ERCP: a retrospective evaluation.

BACKGROUND: Endoscopic ultrasound (EUS)-guided ductal access and drainage (EUS-DAD) of biliary/pancreatic ducts after failed endoscopic retrograde cholangiopancreatography (ERCP) is less invasive than percutaneous transhepatic biliary drainage (PTBD). The actual need for EUS-DAD remains unknown. We aimed to determine how often EUS-DAD is needed to overcome ERCP failure. METHODS: Consecutive duct access procedures (n = 2205; 95 % biliary) performed between June 2013 and November 2015 at a tertiary-care center were reviewed. ERCP was used first line, EUS-DAD as salvage after ERCP, and PTBD when both had failed. Procedures were defined as "index" in patients without prior endoscopic duct access and "combined" when EUS-DAD followed successful ERCP. The main outcomes were the EUS-DAD and PTBD rates. RESULTS: EUS-DAD was performed in 7.7 % (170/2205) of overall procedures: 9.1 % (116/1274) index and 5.8 % (54/931) follow-up. Most index EUS-DADs were performed following (46 %) or anticipating (39 %) ERCP failure, whereas 15 % followed successful ERCP (combined procedures). Among index procedures, the EUS-DAD rate was higher in surgically altered anatomy (58.2 % [39 /67)] vs. 6.4 % [77/1207]); PTBD was required in 0.2 % (3/1274). Among follow-up procedures, ERCP represented 85.7 %, cholangiopancreatography through mature transmural fistulas 8.5 %, and EUS-DAD 5.8 %; no patient required PTBD. The secondary PTBD rate was 0.1 % (3/2205). Six primary PTBDs were performed (overall PTBD rate 0.4 % [9/2205]). CONCLUSIONS: EUS-DAD was required in 7.7 % of ERCPs for benign and malignant biliary/pancreatic duct indications. Salvage PTBD was required in 0.1 %. This high EUS-DAD rate reflects disease complexity, a wide definition of ERCP failure, and restrictive PTBD use, not poor ERCP skills. EUS-DAD effectively overcomes the limitations of ERCP eliminating the need for primary and salvage PTBD in most cases.

Lumen apposing metal stents versus tubular self-expandable metal stents for endoscopic ultrasound-guided choledochoduodenostomy in malignant biliary obstruction.

BACKGROUND AND AIMS: EUS-guided choledochoduodenostomy (EUS-CDS) is an effective option for biliary drainage in malignant biliary obstruction. Lumen apposing metal stents (LAMS) are increasingly been used for EUS-CDS. It is unknown how LAMS compare to tubular self-expandable metal stents (SEMS) for EUS-CDS. Our aim is to compare the clinical outcomes of LAMS versus SEMS for EUS-CDS. PATIENTS AND METHODS: Single-center retrospective cohort study of consecutive patients with unresectable malignant biliary obstruction who underwent EUS-CDS after failed ERCP for initial biliary drainage between 2011 and 2019. Clinical outcomes were compared between patients who had conventional covered SEMS and LAMS placed for EUS-CDS. Outcome measures included unplanned procedural events, technical success, clinical success, adverse events and reinterventions. Survival was analyzed by the Kaplan-Meier method. RESULTS: During the study period 57 patients met inclusion criteria (37 LAMS, 20 SEMS). All EUS-CDS were technically successful (LAMS group 95% CI 90.3-100%, SEMS group 95% CI 83.2-100%). There were no differences between groups in unplanned procedural events (4 LAMS deployment issues, 2 mild bleeding in SEMS group; 10 vs 10.8%), clinical success (37/37 [100%] vs 19/20 [95%]), and short-term adverse events (5/37 [13.5%] vs 4/20 [20%], p = 0.71). Complete follow-up data were available in 41 patients for a mean of 376 ± 145 days. Endoscopic reintervention was required for duodenal stent placement (n = 9) or biliary stent dysfunction (n = 4), with no difference between LAMS and SEMS group (6/37 [16.2%] vs 7/20 [35%]). There were no differences in overall survival between both groups. CONCLUSIONS: EUS-guided choledochoduodenostomy after failed ERCP has equally high technical and clinical success rates with either LAMS or SEMS in patients with malignant biliary obstruction. No differences in adverse events, reinterventions and survival were seen with either type of stent. The cost-effectiveness of LAMS vs SEMS for EUS-guided choledochoduodenostomy remains to be proven.

Endoscopic internal drainage using transmural double-pigtail stents in leaks following upper gastrointestinal tract surgery.

INTRODUCTION: different endoscopic procedures have been proposed for the management of surgical leaks. Endoscopic internal drainage using trans-fistulary double-pigtail plastic stents has emerged as an alternative strategy, especially in fistulae presenting after laparoscopic gastric sleeve. METHODS: a retrospective case series was performed at a single tertiary care center including all upper gastrointestinal post-surgical leaks primarily managed with endoscopic trans-fistulary insertion of double-pigtail plastic stents. Clinical success was defined as the absence of extravasation of oral radiographic contrast and radiological resolution of the collection with adequate oral intake Results: nine patients were included, six (66.6 %) females with a median age of 52.6 years (IQR 47-60). Five cases presented after laparoscopic gastric sleeve, two cases after distal esophagectomies, one after a Roux-en-Y gastric bypass and another one after a pancreaticoduodenectomy. Fistulae measured < 10 mm in five patients (55.6 %) and 10-20 mm in four patients (44.4 %). Six were early leaks. Technical and clinical success was achieved in nine (100 %) and seven (77.8 %) cases, respectively. Seven (77.8 %) patients required ≤ 3 endoscopic procedures. The median hospital stay after the first endoscopic procedure was 12 days (IQR 6.5-17.5 days), while the overall median time until leak healing was 118.5 days (IQR 84.5-170). One patient with a post-esophagectomy intrathoracic leak developed an esophageal-tracheal fistula 37 days after stent deployment. CONCLUSIONS: our results support the use of endoscopic internal drainage in postsurgical abdominal leaks, regardless of the type of surgery. Although only two patients with intrathoracic dehiscence were included.

Randomized clinical trial to assess the mPADSS scale in recovery and home discharge after endoscopy.

BACKGROUND: current clinical practice guidelines recommend the use of objective scales as a criterion for post-endoscopy sedation discharge. OBJECTIVE: to assess the recovery time, complications and patient satisfaction level using the mPADSS scale. MATERIAL AND METHODS: demographic data and medical history were collected. Vital signs, anxiety and abdominal pain were measured pre-endoscopy. Patients were randomized into a control group, discharged according to the usual practice, and the intervention group, who underwent the mPADSS scale every ten minutes, until an objective score was reached. RESULTS: one hundred and eighteen patients were randomized (78 colonoscopies, 32 gastroscopies, three gastro + colonoscopies and 15 endoscopic retrograde cholangiopancreatographies/endoscopic ultrasound [ERCP/USE]). With regard to medical history, there were 36 cases of elevated blood pressure and 19 diabetes cases, 15 with anticoagulant/antiplatelet and 21 with hypnotic/anxiolytic medication. An average of 160 mg of propofol was required per patient, with additional flumazenil and midazolam in 49. There were two episodes of vomiting and three of mild desaturation, all of them in the control group. Sixty patients were included in the control group and 58 in the mPADSS group, who were discharged in 15 and 10 minutes on average respectively (p < 0.005); 24-48h telephone call follow-up data were available for 105 subjects. There were four readmissions (three control and one mPADSS). There were no differences in pain and post-sedation symptoms and the level of satisfaction in terms of attention and duration of stay was similar in both groups. CONCLUSIONS: this study shows the efficiency, safety and patient satisfaction using the mPADSS scale. Thus, its use is recommend.
