Endoscopic vacuum therapy after anastomotic leakage and oesophageal rupture in a tertiary centre
Authors: E. McFiggans, S. Hayat, C. Wadsworth, N. Phillips, C. Parisinos, W. Ahmed
Journal: Endoscopy (2024)

Aims Endoscopic vacuum therapy (EVT) involves vacuum assisted wound closure systems to aid in the management of perforations or post-surgical anastomotic leaks in the gastrointestinal tract (GI). It is thought that the negative pressure produced via the continuous vacuum system provides continuous drainage around the wound which in turn promotes tissue granulation and wound healing. The aim of this study is to describe the experience of EVT in the upper GI tract in a tertiary referral hospital.

Endoscopic management of rectal neuroendocrine tumors in a Spanish tertiary hospital
Authors: C. Amor Costa, M. Tavecchia, P. De Maria Pallares, E. Martin-Arranz, C. Amiama Roig, I. Gonzalez diaz, C. Suarez-Ferrer, A. Burgos García
Journal: Endoscopy (2024)

Aims Rectal neuroendocrine tumors (r-NETs) are rare, although their incidence is increasing [1]. 90% of r-NETs are well differentiated (G1) and<10 mm [2]. The treatment of choice is endoscopic resection in r-NET<10 mm and surgical treatment in those>20 mm. The r-NETs≤10 mm can be resected by endoscopic mucosal resection (EMR). The modified EMR with ligation device (L-EMR) is the technique of choice for higher rates of complete resection (R0) [2]. Endoscopic submucosal dissection (ESD) is considered the most appropriate technique for those>10 mm [2]. There is no consensus on subsequent follow-up. In low-grade r-NETs<10 mm and R0, the risk of recurrence is low and endoscopic revision could be avoided [3]. In this study we perform a descriptive analysis of endoscopically removed r-NETs in our center.

Choledocholithiasis Appearing as Periampullary Mass Lesions on Abdominal Imaging: A Retrospective Case Series
Authors: V. Chuabio, M. A. De Lusong
Journal: Endoscopy (2024)

Aims Distinguishing choledocholithiasis from periampullary masses that may be malignant is paramount given the different management options and prognoses for these conditions. There have been cases where patients with initially suspected periampullary masses turned out to actually have choledocholithiasis. This scenario may confound clinical decision-making and cause unnecessary apprehension on the patient's end. This study therefore aimed to look into possible clinical factors that may be associated with choledocholithiasis having the appearance of suspicious masses on abdominal imaging. Identification of such factors may aid in future diagnoses of choledocholithiasis in instances where abdominal imaging studies would suggest features of periampullary masses despite actual gallstone disease.
Upper digestive hemorrhage : clinical, endoscopic and evolutionary particularities between patients with community and intra-hospital hemorrhage, prospective study
Authors: C. Jioua, B. Jihane, A. Touibi, T. Addajou, R. Berraida, I. Elkoti, R. Fedoua, H. Seddik
Journal: Endoscopy (2024)

Aims The occurrence of upper GI hemorrhage (UGI) remains a potentially serious event, most often resulting in emergency endoscopy even though the majority of UGI is not immediately life-threatening. However, there is a lack of studies comparing the epidemiological profile, risk factors, and endoscopic management between non-hospitalized patients newly admitted to the emergency department for upper GI bleeding (HDH) and those already hospitalized.

Journal: Endoscopy (2024)

Aims Anastomotic dehiscence and leaks, though infrequent, represent serious complications in surgical procedures, often leading to increased morbidity and mortality. Advance in endoscopy have sought to resolve these complications with different techniques. One of them is EndoVacuum Therapy (EVT), indicated to drain collections and close perforations, having promising results with a low adverse event rate [1], despite prolonging the hospitalization and increasing costs.
Diagnostic Accuracy of APRI and FIB-4 for predicting large Esophageal Varices in Liver Cirrhosis: A Retrospective Study
Authors: K. Rais, G. Kharrasse, A. Zazour, O. Elmqaddem, H. Koulali, Z. Ismaili
Journal: Endoscopy (2024)

Aims Upper gastrointestinal endoscopy is the gold standard diagnostic method for screening large varices. However, due to its invasiveness and relatively high cost, the Baveno VII consensus suggests that gastroscopy may not be necessary for patients with transient elastography<20 kPa and platelet count>150×109/L. Transient elastography (FibroScan) is considered the most promising noninvasive technique for evaluating portal hypertension in chronic liver disease. Nevertheless, its availability in lower-middle-income countries is limited. In this retrospective study, we compared the diagnostic performance of the aspartate aminotransferase to platelet ratio index (APRI) and fibrosis-4 index (FIB-4) in predicting the presence of large esophageal varices.
Defining the standard length of Peroral Endoscopic Myotomy (POEM) for achalasia: a systematic review and meta-analysis
Authors: E. Vespa, A. Barchi, F. Azzolini, E. Fasulo, M. C. Fratto, F. V. Mandarino, L. Fanti, D. Esposito, E. Viale, S. Passaretti, E. Savarino, S. Danese
Journal: Endoscopy (2024)

Aims Peroral endoscopic myotomy (POEM) has revolutionized achalasia treatment. However no clear definition of "long", "standard" or "short" POEM exists to date. Evidence suggests myotomy limited to the LES (<6cm) may be highly effective, timesaving and associated with less reflux, yet longer myotomy is commonly performed in clinical practice.

Authors: R. Gomes, N. Dias, C. Soares, Â. Domingues, C. Rodrigues, S. Ventura, D. Martins, R. Araújo, A. Castanheira, A. Silva
Journal: Endoscopy (2024)

Abstract Text An 68 year old woman complained of substernal discomfort and occasional regurgitation of a fleshy mass. There was no history of weight loss, dysphagia or dyspnea. Upper endoscopy revealed a polypoid digitiform mass with a single pedicle arising from the upper esophagus and ending 8 cm below. The CT scan demonstrated an elongated intraluminal esophageal mass extending from the cervical esophagus with a longitudinal length of more than 7 cm. Endoscopic ultrasound revealed a subepithelial lesion sparing the muscaris propria layer. The decision was made to proceed with endoscopic polypectomy, which was successfully performed using a hot snare after prophylactic hemostasis with an endoloop. Histology revealed a fibrovascular polyp. The patient had an uneventful recovery and became asymptomatic. We are presenting this case due to it's rarity and atypical presentation. [1] [2]
A rare case of gastroesophageal junction lesion
Authors: X. Zhao, L. Dan
Journal: Endoscopy (2024)

Abstract Text A 55-year-old man came to our institution for a large lesion at gastroesophageal junction. Although he had undergone endoscopic mucosal resection of an adenoma in distal esophagus 3 years previously. Esophagogatrduodenoscopy showed scattered exophytic papillare and lobulate lesions located from lower esphagus to cardia, with irregular Z-line. Magnifying endoscopy with narrow-band imaging showed dilated microvessels in the swollen glands. Therefore, endoscopic submucosal dissection was performed. The size of the resected specimen was 8×2.5cm. Histological examination showed that the squamous papilloma originated from the esophagus and invaded the cardia. The patient's postoperative course was uneventfully, and confirmed through endoscopic examination one year later that there was no recurrence. Endoscopic submucosal dissection is surely the appropriated technique to remove this kind of lesion.
Endoscopic Management of Post-Surgical Biliary Leaks: A Two-Center Experience
Authors: D. Quintini, F. Ferrara, G.E. M. Rizzo, T. Salvatore, G. Rancatore, L. Carrozza, R. Miraglia, D. Ligresti, I. Tarantino, M. Traina
Journal: Endoscopy (2024)

Aims Post-surgical biliary leaks (PSBL) are one of the most prevalent and significant complications emerging after liver or biliary tract surgeries, possibly leading to life-threatening complications. Different surgical interventions can result in different types, locations or extent of the leaks, nevertheless the mechanism that maintains the leak is always related to the pressure gradient within the biliary tree. Endoscopic retrograde cholangiopancreatography (ERCP) alone or combined with a percutaneous transhepatic approach (Rendez Vous) as treatment of PSBL obtains optimal outcomes due to the possibility to modify the pressure gradient in the biliary tree.

Single center experience with Exposed Endoscopic Full-Thickness Resection (E-EFTR) of rectal lesions with scarring or suspected deep submucosal invasion
Authors: M. Spandre, F. Frigo, G. Testa, D. Arese, A. Garripoli, G. Giudici, M. A. La Terra, N. Sapone, F. Coppola
Journal: Endoscopy (2024)

Aims the endoscopic management of rectal lesions displaying scarring or suspected deep submucosal invasion poses a challenging task. Standard endoscopic resection techniques like Full-Thickness Resection Device-assisted (FTRD) and Endoscopic Submucosal Dissection (ESD) present some limitations with these kinds of lesions. FTRD use is constrained by lesion size and location, while ESD is limited in obtaining histologically complete (R0) resections in case of deep submucosal involvement and in resecting scarring lesions. Here we present our initial experience with E-EFTR for the treatment of complex rectal lesions.
Endobiliary radiofrequency ablation – a promising new tool to prolong stent patency in patients with malignant biliary obstruction
Authors: Y. Petkova, P. Karagyozov, I. Tishkov
Journal: Endoscopy (2024)

Aims The main approach for the management of unresectable malignant biliary obstruction is ERCP with stenting followed by palliative chemotherapy. However, a major concern is the rate of recurrent biliary obstruction/RBO/. Endobilliary radiofrequency ablation (EB-RFA) is a new endoscopic technique that can be an adjunctive tool in prolonging the period of stent patency and patient survival.The primary endpoints were to evaluate the correlation between the period of stent patency,type of placed stents and subsequent chemotherapy in patients with malignant biliary obstruction/MBO/treated with ЕB-RFA. Secondary endpoints were the overall efficacy and safety of the procedure in terms of survival and adverse events/AE/.

Journal: Endoscopy (2024)

Aims Gastritis cystica profunda (GCP) is a rare entity characterised by the cystic dilatation and foveolar hyperplasia in the mucosa and submucosa. The etiopathogenesis is unknown. It has been described in chronic inflammatory situations: gastric surgery, Helicobacter pylori (H.pylori) infection, chronic gastritis or biliary reflux. Diagnosis is histological based on cystic dilatation of the glands in the mucosal and submucosal layer, foveolar hyperplasia and inflammatory infiltrate.
EUS-guided pancreatic duct drainage: endoscopic and clinical practice experience
Authors: M. Marasco, S. Godat, B. Annibale, F. Panzuto, D. Galasso
Journal: Endoscopy (2024)

Aims EUS-guided pancreatic duct drainage (EUSPDD) is an endoscopic procedure which is indicated in symptomatic patients with evidence of pancreatic duct obstruction after failure of transpapillary drainage or impossibility to perform EWSL in the contest of chronic pancreatitis or altered anatomy causes (e.g. Whipple or Roux-en-Y surgery). Nowadays, it is a challenging procedure performed by few endoscopist. Clinical and technical success rate is still lacking and heterogenous, therefore acquisition of new data and experience is necessary.

Authors: Saad Irfan, Maudlyn O. Etekochay, Atanas G. Atanasov, Vishnu P. Prasad, Ramesh Kandimalla, Mohammad Mofatteh, Priyanka V, Talha B. Emran
Journal: International Journal of Surgery (2024)

As one of the leading causes of global mortality and morbidity, various neurological diseases cause social and economic burdens. Despite significant advances in the treatment of neurological diseases, establishing a proper disease model, especially for degenerative and infectious diseases, remains a major challenging issue. For long, mice were the model of choice but suffered from serious drawbacks of differences in anatomical and functional aspects of the nervous system. Furthermore, the collection of post-mortem brain tissues limits their usage in cultured cell lines. Overcoming such limitations has prompted the usage of stem cells derived from the peripheral nervous system, such as the cells of the olfactory mucosa as a preferred choice. These cells can be easily cultured in vitro and retain the receptors of neuronal cells life-long. Such cells have various advantages over embryonic or induced stem cells, including homology, and ease of culture and can be conveniently obtained from diseased individuals through either biopsies or exfoliation. They have continuously helped in understanding the genetic and developmental mechanisms of degenerative diseases like Alzheimer's and Parkinson's disease. Moreover, the mode of infection of various viruses that can lead to post-viral olfactory dysfunction, such as the Zika virus can be monitored through these cells in vitro and their therapeutic development can be fastened.
