Flexible endoscopic treatment of Zenker's diverticulum-a retrospective, observational multicenter study.

Background: The European Society of Gastroenterology and Endoscopy recommends a primarily flexible endoscopic approach for the treatment of Zenker's diverticulum. Due to the rarity of the disorder, evidence for its effectiveness and safety comes mainly from small, retrospective, single-center studies.

Methods: In this retrospective, observational, multicenter cohort study, data from six German tertiary referral centers were analyzed.

New ipsilateral full endoscopic interlaminar approach for L5-S1 foraminal and extraforaminal decompression: technique description and initial case series.

Background: The L5-S1 interlaminar access described in 2006 by Ruetten et al. represented a paradigm shift and a new perspective on endoscopic spinal approaches. Since then, the spinal community has shown that both the traditional ipsilateral and novel contralateral interlaminar approaches to the L5-S1 foramen are good alternatives to transforaminal access.

Cold Versus Hot Snare Endoscopic Resection of Large Nonpedunculated Colorectal Polyps: Randomized Controlled German CHRONICLE Trial.

Background & Aims: Endoscopic mucosal resection (EMR) is standard therapy for nonpedunculated colorectal polyps ≥20 mm. It has been suggested recently that polyp resection without current (cold resection) may be superior to the standard technique using cutting/coagulation current (hot resection) by reducing adverse events (AEs), but evidence from a randomized trial is missing.

Methods: In this randomized controlled multicentric trial involving 19 centers, nonpedunculated colorectal polyps ≥20 mm were randomly assigned to cold or hot EMR.

Endoscopic submucosal dissection for early esophageal adenocarcinoma: low rates of metastases in mucosal cancers with poor differentiation.

Background And Aims: Endoscopic resection is accepted as standard treatment for intramucosal esophageal adenocarcinoma (EAC) that is well or moderately differentiated. Poor differentiation (PD) is judged as a risk factor for lymph node metastasis (LNM), and surgery is recommended. However, the evidence for this recommendation is weak.

Percutaneous Radiofrequency Disc Decompression: A Study of 27 Patients.

Background: Percutaneous radiofrequency nucleoplasty is a true minimally invasive technique for treatment for radiculopathy caused by contained disc protrusions. This minimally invasive procedure uses controlled thermoablation for reducing the intervertebral disc and decompressing the lumbar nerve root. Material and Methods: Our study is a prospective analysis of 27 patients aged from 30 to 64 years with lumbar disc protrusion who were treated with percutaneous radiofrequency disc decompression (PRFD) between May 2018 and May 2019.

Perioperative Atezolizumab Plus Fluorouracil, Leucovorin, Oxaliplatin, and Docetaxel for Resectable Esophagogastric Cancer: Interim Results From the Randomized, Multicenter, Phase II/III DANTE/IKF-s633 Trial.

Purpose: This trial evaluates the addition of the PD-L1 antibody atezolizumab (ATZ) to standard-of-care fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) as a perioperative treatment for patients with resectable esophagogastric adenocarcinoma (EGA).

Methods: DANTE started as multicenter, randomized phase II trial, which was subsequently converted to a phase III trial. Here, we present the results of the phase II proportion, focusing on surgical pathology and safety outcomes on an exploratory basis.

Full-Endoscopic Technique for Posterior Fossa Decompression in Chiari Malformation.

Background And Importance: Full-endoscopic techniques are well-described for spinal procedures. Although endoscopic-assisted techniques are reported for posterior fossa decompression (PFD) in Chiari malformation (CM), a full-endoscopic technique is yet to be reported in these patients. The aim of this study was to present and describe a full-endoscopic technique for PFD in patients with CM.

Full-endoscopic technique for posterior fossa decompression in Chiari malformation type I: An anatomical feasibility study in human cadavers.

Although endoscope-assisted techniques have been described, a full-endoscopic approach is yet to be performed for posterior fossa decompression (PFD) in Chiari malformation type I (CM-I). This study aims to describe the full-endoscopic PFD technique and evaluate its feasibility. Five fresh-frozen anonymized adult human cadavers were operated on using an endoscope with an oval shaft cross-section with a diameter of 9.

Characteristics and endoscopic treatment of interventional and non-interventional iatrogenic colorectal perforations in centers with high endoscopic expertise: a retrospective multicenter study.

Background: Iatrogenic colorectal perforation is a rare event with a relevant mortality and the need for surgical therapy in around ¾ of cases.

Methods: In this retrospective multicentric cohort study iatrogenic colorectal perforations from 2004 to 2021 were analyzed. Primary outcome parameters were incidence and clinical success of 1st line endoscopic treatment.

[Essential trace elements, vitamins, and selected electrolytes in complementary medicine for cancer patients].

Objective: Are there any evidence-based medicine (EBM)-supported treatment approaches of complementary and alternative medicine (CAM) methods for urological oncologists?

Methods: We reviewed the actual German S3 guidelines "Supportive Care" and "Complementary Medicine" as well as the online-tool Onkopedia for recommendations about essential trace elements (Zn, Se, Mn, Fe), vitamins (A, B, C, D, E), and electrolytes (Mg, Ca). Furthermore, we added results of randomized trials to present potential future developments.

Results: Each therapy with micronutrients should be based on laboratory observation of a deficit.

One miniplate versus two miniplates in the fixation of mandibular angle fractures. An updated systematic review and meta-analysis.

Purpose: The aim of this study is to compare the outcomes after using one miniplate fixation in the external oblique ridge versus two miniplate fixation for mandibular angle fractures.

Methods: A systematic review of MEDLINE (via PubMed), Scopus and Cochrane Library database was performed (last search date: 04 February 2022) according to the PRISMA guidelines. The research question was addressed using the PICO criteria.

Towards a More Realistic Appraisal of Complications Following Staged Lateral Lumbar Interbody Fusion: A Single Institution Series.

Study Design: Retrospective cohort study.

Objectives: With steadily increasing implementation of far lateral approaches in spine surgery, surgeons can utilize the advantages of different approaches synergistically to ensure an optimal patient outcome. Our single institution study aimed to assess the complication rates of patients who underwent a lateral interbody fusion as the index procedure and additional anterior or posterior instrumentation as part of a planned staged surgical reconstruction effort.

Serum magnesium: time for a standardized and evidence-based reference range.

Magnesium deficiency can have serious health consequences. Low magnesium intake or low serum levels are risk factors for e.g.

[Magnesium: Relevance for general practitioners - a position paper of the Society for Magnesium Research e. V.].

Magnesium deficiency is to be expected in the population and particularly among risk groups. Magnesium deficiency can cause numerous symptoms, is per se pathological and thus requires treatment. Diagnostics is based on clinical symptoms in conjunction with anamnestic criteria and laboratory parameters.

AOSpine Consensus Paper on Nomenclature for Working-Channel Endoscopic Spinal Procedures.

Study Design: International consensus paper on a unified nomenclature for full-endoscopic spine surgery.

Objectives: Minimally invasive endoscopic spinal procedures have undergone rapid development during the past decade. Evolution of working-channel endoscopes and surgical instruments as well as innovation in surgical techniques have expanded the types of spinal pathology that can be addressed.

Early recognition of patients with axial spondyloarthritis-evaluation of referral strategies in primary care.

Objective: Chronic inflammatory back pain (IBP) is frequently reported in axial SpA (axSpA) but also in the general population. We evaluated a recently proposed two-step referral system for early recognition of axSpA in primary care and compare it with other combinations of symptoms and SpA-related items.

Methods: Consecutive chronic back pain patients ≤45 years of age answered a questionnaire and were seen by a primary care physician who decided whether HLA-B27 needed to be determined.

Endoscopic Lumbar Decompression.

The most common causes of degenerative narrowing of the spinal canal are disc herniations and spinal canal stenosis. The standard surgical procedure for lumbar spinal canal stenosis today is microsurgical, microscope-assisted decompression. Full-endoscopic decompression is now also technically feasible and more widespread because of the development of surgical access techniques and instruments.
