Objective: To evaluate the potential utility of a new endoscopically placed expandable tracheal stent in the treatment of benign symptomatic stenoses of the cervical trachea.
Study Design: Pilot study utilizing a prospectively followed case series.
Methods: An initial group of six patients undergoing stent placement was examined with rigid and flexible endoscopy under anesthesia immediately following stent placement and at postoperative 6 to 8 weeks. Subsequently each patient was followed clinically for a minimum of 6 months.
Results: All stents were well tolerated with no observed complications. Immediate reversal of symptomatic airway obstruction without the need for adjunctive tracheotomy was noted in every patient. At 6 weeks, endoscopic confirmation of complete intraluminal mucosalization without formation of any granulation tissue or scar bands within the stented areas was noted in each case.
Conclusions: This preliminary pilot study supports the use of nitinol expandable tracheal stents as an alternative in the treatment of benign symptomatic tracheal stenoses.

Ipsilateral Nasoseptal Flaps in a Transpterygoid Approach: Technical Pearls and Reconstruction Outcomes.
J Neurol Surg B Skull Base

Transpterygoid approaches to the skull base require dissection of the sphenopalatine artery, potentially compromising the option to harvest an ipsilateral nasoseptal flap (NSF) for reconstruction. In cases where other reconstructive options are limited, it may be necessary to utilize a NSF ipsilateral to the transpterygoid approach. Here, we describe the technique of NSF pedicle preservation with reconstruction outcomes.

Access to advanced medical procedures, such as gastrointestinal (GI) endoscopy, is critical for effective healthcare. In Sub-Saharan Africa, including Sudan, GI endoscopy services remain limited, posing significant barriers to early diagnosis and treatment of GI diseases. Expanding GI endoscopy services in Sudan and other regions of Sub-Saharan Africa is crucial to improve early detection, reduce mortality, and increase the cost-effectiveness of healthcare delivery.

Background: Anastomotic leakage (AL) is a major concern following esophagectomy due to the associated morbidity and mortality. The impact of hospital volume on postoperative outcomes after esophagectomy has previously been reported. The aim of this study was to analyze the current trends in postoperative anastomotic leakage and associated failure-to-rescue after esophagectomy in relation to hospital volume in German acute care hospitals using real-world data from the German Diagnosis-Related Groups (G-DRG) database.

The increasing detection of submucosal tumors (SMTs) in the upper gastrointestinal tract (UGI) is due to the increased clinical use of endoscopy and imaging technology. Some of these SMTs have malignant potential and may cause clinical symptoms. Thus, it is recommended in clinical guidelines to consider resection of these SMTs.

In the medical field, endoscopic video analysis is crucial for disease diagnosis and minimally invasive surgery. The Endoscopic Foundation Models (Endo- FM) utilize large-scale self-supervised pre-training on endoscopic video data and leverage video transformer models to capture long-range spatiotemporal dependencies. However, detecting complex lesions such as gastrointestinal metaplasia (GIM) in endoscopic videos remains challenging due to unclear boundaries and indistinct features, and Endo-FM has not demonstrated good performance.
