Prospective multi-center Audit of “real-life” Common Bile Duct Stones (CBDSs) clearance at Index Endoscopic Retrograde Cholangio-Pancreatography (ERCP)
Authors: K. Das, K. Banik, S. Chowdhury
Journal: Endoscopy (2024)

Methods In this prospective cross-sectional study from 2 centers from Eastern India, consecutive patients (age>12 years) with CBDSs undergoing index ERCP with native papilla and satisfying pre-determined inclusion criteria, were enrolled from August 2020-July 2021. Demographic, clinical, radiological and ERCP data were recorded in a structured proforma. The performing endoscopist entered the details of Cholangiography including number, size, location and shape of stones, CBD diameter, distal angulation, etc. and interventions performed, e.g., cannulation and sphincterotomy, stone-extraction with balloon/basket, use ancillary Endoscopic Papillary Large Balloon Dilatation (EPLBD) or Mechanical Lithotripsy (ML), etc. All patients were followed for 14 days post-ERCP for capturing complications. Those who underwent biliary stenting (for failed clearance, etc.) were followed, 2 monthly, for 6 months. All patients were again contacted at the end of 1-year to record the ultimate outcome of ERCP for CBDSs. Statistical analysis was done according to standard methods. A two-tailed p-value<0.05 was considered significant

Journal: Endoscopy (2024)

Aims Endoscopic submucosal dissection (ESD) for superficial non-ampullary duodenal epithelial tumors (SNADETs) larger than 20 mm has not been common due to the difficulty of the procedure and its related complications. Considering the simplicity and safety of the procedure, we have introduced gel immersion ESD (GI-ESD) in 2021 using a Clutch Cutter as a resection device. This retrospective study aims to compare the short-term outcomes between GI-ESD and the conventional ESD for SNADETs.
Endoscopic anterior fundoplication after POEM Myotomy in the same session. POEM-F
Authors: P. Rosón, F. M. Fernandez, A. M. Angeles, A. París, V. Cristina, M. Alberto
Journal: Endoscopy (2024)

Abstract Text Peroral endoscopic myotomy (POEM) is a well-established treatment for achalasia, however, gastroesophageal reflux after POEM remains a problem. Endoscopic fundoplication after POEM (POEM+F) has recently been described to reduce post-POEM GERD.The procedure consists of two steps: anterior POEM and fundoplication. Once the myotomy is finished, the peritoneum is dissected using a coagrasper, the pneumo is created using CO2 insufflation. An endoloop is placed and fixed with the help of four clips to the distal anchorage site, and to the final edges of the esophageal muscle myotomy. Finally, the loop is closed creating the anterior fundoplication, The entire procedure added 45 minutes to the standard POEM technique.

Authors: F. Shibli, H. Awadie, S. Shamah, A. Shtarkman, A. Zoabi, I. M. Gralnek
Journal: Endoscopy (2024)

Aims The aims of this study were to determine whether intraprocedural endoluminal functional lumen imaging probe (EndoFLIP) can guide the endoscopist in adjusting the length of the myotomy a​ccording to the distensibility index (DI) and minimum diameter (Dmin) values and to examine this impact on clinical outcomes of peroral endoscopic myotomy (POEM).
Risk of lymph node metastasis and local or distant recurrence after endoscopic resection of T1 colorectal adenocarcinoma with submucosal invasion&gt;1000 mm and no other histological pejorative factors
Authors: L. Barthet, T. Lambin, F. Corre, V. Lepilliez, S. Leblanc, J. Jacques, T. Wallenhorst, J. P. Ratone, J. B. Chevaux, S. Marion, Y. Le Baleur, G. Rahmi, A. Berger, T. Degand, D. Karsenti, R. Gerard, N. Etchepare, J. Santos-Antunes, T. Fenouil, F. Subtil, S. Chaussade, M. Pioche
Journal: Endoscopy (2024)

Aims Endoscopic resections of T1 colorectal adenocarcinoma are considered curative when several histological criteria are met: the resection must be R0, with no lympho-vascular emboli, no significant budding, no poorly differentiated component, and the depth of invasion in the submucosa must not exceed 1000µm [1] [2]. However, these different risk criteria do not have the same impact on the lymph node prognosis of these lesions. Some recent data show that the histological criterion of submucosal invasion depth<1000µm may not be an independent risk criterion for lymph node metastasis [3], and the risk associated with it seems low [4]. The aim of this study was to evaluate the risk of lymph node metastasis or recurrence in cases of endoscopic resection with or without complementary surgery of T1 colorectal cancer with submucosal invasion of more than 1000 µm and without any other pejorative histological factors.

Transpapillary gallbladder drainage reduces the frequency of biliopancreatic events in the waiting period for surgery, even in patients without comorbid diseases
Authors: Y. E. Parlar, E. Parlak, B. ÖZtürk, O. Keskin, T. Kav
Journal: Endoscopy (2024)

Aims In patients with acute cholecystitis and choledocholithiasis undergoing Endoscopic Retrograde Cholangiopancreatography (ERCP) followed by interval cholecystectomy (waiting period 6 weeks-3 months), the frequency of recurrent biliopancreatic events before surgery is reported to be 17-41.8%. Transpapillary Gallbladder Drainage (TGBD) is indicated in this patient group if there are comorbidities preventing surgery. This study aimed to compare biliopancreatic events occurring during the waiting period for cholecystectomy between patients who underwent TGBD outside the classical indication and those who underwent ERCP for the same indication but did not receive TGBD.

Video Assessment Of Large Non-Pedunculated Colorectal Polyps Similarly Predicts Hard Outcomes In The Assessment Of Submucosal Invasive Cancer Risk Compared To Live Assessment
Authors: M. Montori, S. Ridolfo, P. J. Poortmans, S. Smeets, M. E. Argenziano, T. Tornai, L. Debels, L. Desomer, D. J. Tate
Journal: Endoscopy (2024)

Aims Cancer in large non-pedunculated colorectal polyps (LNPCPs) is poorly discriminated outside expert centres. It is unknown whether video- is comparable to live-assessment for determining submucosal invasion (SMI) in LNPCPs. Video-assessment has multiple advantages including collaborative discussion of imaging findings at multi-disciplinary meetings avoiding extra assessment procedures for patients or incorrect decision-making. We compared live LNPCP assessment with analysis of videos produced by an expert.

Authors: B. Gellért, A. Rancz, J. Hoferica, B. Teutsch, S. V. Dániel, B. Erőss, P. J. Hegyi, P. Hegyi, I. Hritz
Journal: Endoscopy (2024)

Aims Performing endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y gastric bypass (RYGB) anatomy represents a real challenge for endoscopists. The most widely used options for ERCP in these cases are enteroscopy-assisted ERCP (EA-ERCP), laparoscopy-assisted ERCP (LA-ERCP), and endoscopic ultrasound-directed ERCP (EDGE). Our aim is to compare EA-ERCP, LA-ERCP, and EDGE in terms of safety and efficacy by performing a systematic review and meta-analysis.

Authors: S. C. Albers, R. Geitenbeek, E. Van Geffen, E. Consten, M. Kusters, P. Tanis, E. Dekker, J. Wiggers, B. A. Bastiaansen, R. Hompes
Journal: Endoscopy (2024)

Aims Advances in transanal surgical and endoscopic resection techniques have increased the use of local excision (LE) as a diagnostic and potentially organ-sparing approach for early-stage (cT1-2N0) rectal cancer (RC). For pT1 RC, total mesorectal excision (TME) can be omitted if histological risk factors for lymph node metastasis (LNM) and local recurrence are absent, regardless of submucosal invasion depth, as defined by the current Dutch CRC guideline. However, for pT2 RC, completion TME is recommended, irrespective of the presence of histological risk factors and despite the potentially varying associated risks for LNM. At present, little is known about the incidence and predictive value of histological risk factors in pT2 RC. This study aims to describe the association between histological risk factors and LNM rate in pT2 RC.

Journal: Endoscopy (2024)

Aims Acute pancreatitis is an acute inflammation of the pancreatic gland following autodigestion by its own enzymes. There are 2 forms: the benign interstitial edematous pancreatitis and the severe necrotizing form. It is a medical-surgical emergency whose severity can be evaluated by several scores. Our work aimed to evaluate the severity of acute pancreatitis by the SIRS (Systemic Inflammatory Response Syndrome) and SOFA (Sepsis-related Organ Failure Assessment) scores.
Difficult arterial bleeding during gastric ESD: self-assembling peptide gel saves the day!
Authors: T. I. Amza, A. Bengus, R. B. Mateescu, A. M. Voiosu
Journal: Endoscopy (2024)

Abstract Text We performed ESD for a 4-cm early gastric cancer Paris type IIa+c lesion located on the lesser curvature in a 77 year-old man. He was cardiostimulated for atrial fibrillation and received the last dose of low molecular weight heparin 12 hours prior. Halfway through dissection with the IT2-knife an important arterial bleeding occurred while injection and coagulation by coagrasper failed. In order to finish the procedure, we opted for application of self-assembling peptide gel with which the hemostasis was achieved. We continued dissection in another region and finished the resection by cutting through the transparent gel with no intraprocedural recurrence of the bleeding. Pathology confirmed R0 resection of a G1 intestinal-type adenocarcinoma eCura A and no recurrence was seen at follow-up. The case illustrates a procedure-rescuing use of hemostatic gel, allowing optimal patient outcome.

Adenomas per colonoscopy is superior to adenoma detection rate as a quality indicator of colonoscopy
Authors: Y. S. Suh, J. S. Koo, D. W. Kim, H. K. Shin, J. W. Kim, D. K. Choi, K. H. Park
Journal: Endoscopy (2024)

Aims Adenoma detection rate (ADR) is most widely used as a quality indicator of colonoscopy because of facileness of calculation. Another indicator, adenoma miss rate (AMR) is most critical tool of the quality of colonoscopy, but not easy to calculate routinely. In our study, we assessed to figure out association of AMR with several easy-calculatable quality indicators of not only ADR but also adenomas per colonoscopy (APC), adenomas per positive participant (APP) and ADR-plus.

Endoscopic ultrasound guided biopsy of focal liver lesions: a tertiary care single center experience
Authors: G. Rancatore, D. Ligresti, G.E. M. Rizzo, L. Carrozza, M. Traina, I. Tarantino
Journal: Endoscopy (2024)

Methods All consecutive patients who underwent EUS-FNB of a focal liver lesion between 2003 and 2023 were retrospectively analyzed. All procedures were performed with patients under deep sedation. Efficacy was evaluated considering technical success, adequacy and accuracy of histological diagnosis. Adequacy was defined as the ability of the technique to confer a histological diagnosis. Accuracy was define as the agreement between definitive histology after surgery (for resectable patients), radiologic findings or clinical course during follow-up. "Malignant" was defined as a case with histologically malignant findings", and "benign" cases were those with "histologically benign findings on EUS-FNB and no tumor growth even after one-year follow-up". Sensitivity and specificity were also evaluated. Adverse events were defined according to American Society of Gastrointestinal Endosocopy (ASGE) lexicon.

Authors: T. rizkala, C. Hassan, M. Yuichi, M. Spadaccini, G. Antonelli, A. Facciorusso, B. B. Houwen, E. Dekker, J. Weiquan Li, E. Rondonotti, K. Khalaf, M. Misawa, M. Menini, A. Schilirò, H. Patel, O. Pech, S. Baumer, A. Fugazza, R. Maselli, K. R. Douglas, P. Sharma, A. Repici
Journal: Endoscopy (2024)

Aims According to the Resect and Discard strategy, endoscopists can replace post-polypectomy pathology with real-time prediction (optical diagnosis) of polyp histology during colonoscopy. This strategy is only applicable to small polyps≤5mm and if the endoscopist prediction was made with high confidence. The variability in real-time optical diagnosis among different endoscopists can be standardized by the high accuracy expected from computer-aided diagnosis systems (CADx). The aim of this meta-analysis is to provide a preliminary estimate of the accuracy of CADx and to assess its effect in clinical practice.
