Endoscopic ultrasound-guided therapies in the treatment of gastric varices: An in-depth examination of associated adverse events.

The Baveno VII consensus, released in 2023, recommends that the endoscopic treatment of choice for managing bleeding gastric varices (GV) is endoscopic ultrasound (EUS)-guided treatment, specifically EUS-guided cyanoacrylate (CYA) glue injection. This approach has been endorsed due to its efficacy in controlling bleeding while reducing rebleeding rates, compared to other endoscopic techniques. Despite its efficacy, CYA injection for GV has been linked to rare but serious adverse events, such as glue embolization leading to pulmonary embolism, infection/bacteremia, splenic infarction, intra-procedural and post-procedural complications.

Anal defecatory function in ulcerative colitis patients after total proctocolectomy and ileal pouch-anal anastomosis: a prospective cohort study.

Background: Total proctocolectomy (TPC) followed by ileal pouch-anal anastomosis (IPAA) remains the only viable option whenever different treatment modalities fail in patients with ulcerative colitis (UC).

Objective: Prospective cohort pre/post study examining the anal defecatory function and competence in UC patients undergoing TPC plus IPAA using high-resolution anorectal manometry (HR-ARM).

Patients: Patients undergoing TPC and IPAA were enrolled in the study and subjected to HR-ARM prior to and 6 months after surgery.

Sedation during endoscopic procedures: a Hellenic Society of Gastroenterology Position Statement.

Administration of sedation by non-anesthesiologists during gastrointestinal endoscopy remains highly controversial in Greece. The aim of this set of 16 position statements prepared by experts in the field on behalf of the Hellenic Society of Gastroenterology is to aid gastroenterologists in their everyday clinical practice and provide evidence for the best use of drugs for the sedation of patients who undergo an endoscopy. The statements address issues such as the level of sedation required, the best drugs used, their mode of action, their side-effects and possible ways to counter their action, and were adopted if at least 80% of all participants agreed upon them.

Efficacy and safety of transpancreatic sphincterotomy in endoscopic retrograde cholangiopancreatography: a retrospective cohort study.

Background: Difficult cannulation represents a common obstacle during endoscopic retrograde cholangiopancreatography (ERCP). We assessed the efficacy and adverse events of transpancreatic sphincterotomy (TPS), and investigated potential associated confounders.

Methods: All patients referred to our department for ERCP during 2015-2020 were eligible if they had intact papilla and visceral anatomy.

State of the Art in Endoscopic Therapy for the Management of Gastroenteropancreatic Neuroendocrine Tumors.

Gastroenteropancreatic neuroendocrine neoplasms (GEP NENs) comprise a heterogeneous group of slow growing tumors arising from the neuroendocrine cells of the gastrointestinal (GI) tract. Although they are considered relatively rare, their incidence is rising and it is believed that the more frequent use of endoscopy and imaging studies have at least in part contributed to the increased diagnosis especially of localized neoplasms. The management of these neoplasms should be guided by a multidisciplinary NEN team following appropriate staging investigations.

Role of autophagy in gastric carcinogenesis.

Gastric cancer represents a common and highly fatal malignancy, and thus a pathophysiology-based reconsideration is necessary, given the absence of efficient therapeutic regimens. In this regard, emerging data reveal a significant role of autophagy in gastric oncogenesis, progression, metastasis and chemoresistance. Although autophagy comprises a normal primordial process, ensuring cellular homeostasis under energy depletion and stress conditions, alterations at any stage of the complex regulatory system could stimulate a tumorigenic and promoting cascade.

Ulcerative Colitis in Hematological Malignancies: Paraneoplastic Manifestation or Coincidental Bystander?

Evidence of coexistence of diverse hematological malignancies-lymphoma, leukemia, multiple myeloma, and myelodysplastic syndromes-and either ulcerative colitis or Crohn's disease can be found in the literature. However, a more "systemic" effort to reach further and examine the potential of either one as paraneoplastic manifestation has not been performed. Based on these, three cases of ulcerative colitis manifesting before, simultaneously, and after the onset of different hematological malignancies are presented and critically evaluated.

Liver cirrhosis-effect on QT interval and cardiac autonomic nervous system activity.

Aim: To examine the impact of liver cirrhosis on QT interval and cardiac autonomic neuropathy (CAN).

Methods: A total of 51 patients with cirrhosis and 51 controls were examined. Standard 12-lead electrocardiogram recordings were obtained and QT as well as corrected QT interval (QTc) and their dispersions (dQT, dQTc) were measured and calculated using a computer-based program.

Laparoendoscopic rendezvous may be an effective alternative to a failed preoperative endoscopic retrograde cholangiopancreatography in patients with cholecystocholedocholithiasis.

Background: Endoscopic retrograde cholangiopancreatography (ERCP), followed by laparoscopic cholecystectomy (LC), remains the standard way of management for patients with cholecystocholedocholithiasis. Laparoendoscopic rendezvous (LERV), a combined procedure for removing the gallbladder laparoscopically and clearing the common bile duct (CBD) endoscopically at the same time, could be an attractive alternative. The aim of this study was to compare LERV with classic ERCP in patients with cholecystocholedocholithiasis.

Acute appendicitis in a duplicated appendix.

Introduction: Double appendix represents an extremely rare and commonly "missed" diagnosis, often with life threatening consequences.

Presentation Of Case: In this case report we present an interesting case of operative treatment of acute appendicitis in a doubled vermiform appendix stemming operative pitfalls. A 23-year-old female was admitted to the emergency room department complaining of diffuse abdominal pain, nausea, and vomiting over the past 36h.

Imbalance of tissue inhibitors of metalloproteinases (TIMP) - 1 and - 4 serum levels, in patients with inflammatory bowel disease.

Background: Tissue inhibitors of metalloproteinases (TIMPs) play a key role in tissue degradation and remodeling. Since chronic inflammation is associated with tissue remodeling in inflammatory bowel disease (IBD), we evaluated serum TIMP-1 and TIMP-4 levels in IBD patients, in comparison with healthy controls (HC).

Methods: TIMP-1, TIMP-2 and TIMP-4 serum levels were determined in 53 patients with ulcerative colitis (UC), 52 patients with Crohn's disease (CD) and 50 HC, by means of commercially available enzyme-linked immunosorbent assays.
