Summary: Endoscopic and microscopic ossiculoplasty have similar postoperative hearing results in patients with chronic otitis media, with a trend towards shorter operation time and reduced morbidity for the endoscopic approach. Further randomized controlled trials are needed to confirm these findings.

Summary: This paper describes the use of an aluminum nitride (AlN) piezoelectric micromachined ultrasound transducer (PMUT) array for high-resolution photoacoustic (PA) imaging. By utilizing the high-order resonance modes of the PMUT, the imaging resolution is improved. The PMUT, based on microelectromechanical systems (MEMS), is suitable for PA endoscopic imaging of blood vessels and bronchi due to its small size and high sensitivity. The study focuses on the characterization and analysis of the PMUT's high-order resonance modes, which provide higher frequencies and wider bandwidth for PA signal detection, leading to increased resolution compared to working at the fundamental resonance mode.

Summary: High-definition endoscopy is crucial in the initial diagnosis of inflammatory bowel disease (IBD), helping to characterize inflammation and differentiate between ulcerative colitis and Crohn's disease. In addition to videoendoscopy, the use of dyes sprayed via a catheter can improve detection rates of intraepithelial neoplasia. Virtual chromoendoscopy techniques should not be the sole surveillance strategy in IBD, while the results of oral methylene blue formulation show promise in increasing acceptance rates of classic chromoendoscopy.

Summary: Current endoscopy techniques face challenges in achieving high resolution and large imaging depth, resulting in limitations for early gastric cancer diagnosis. This study presents the development of a label-free, large-depth, three-dimensional chromatic reflectance confocal endomicroscopy, which demonstrates great potential for providing important morphological information in gastric cancer diagnosis.

Summary: In a multicentre prospective cohort study, patients with infected necrotising pancreatitis who underwent endoscopic drainage were compared. The results showed that LAMS did not reduce the need for necrosectomy and the rate of bleeding complications was similar.

Summary: The study compared the performance of disposable and reusable gastroscopes in gastroscopy and found that while both had similar success rates in capturing images of anatomic sites, the disposable gastroscopes had lower imaging quality scores and longer operating times.

Summary: Comparing transnasal endoscopy (TNE) to esophagogastroduodenoscopy (EGD) in preoperative screening for bariatric surgery, TNE was found to be associated with less post-procedure care, shorter procedure time, and fewer charges compared to EGD. TNE could be considered as an initial screening tool for patients undergoing bariatric surgery, while EGD could be selectively used in patients with abnormal TNE findings.

Summary: Flexible endoscopy appears to be as effective and safe as open surgery in the treatment of Zenker's diverticulum. Endoscopy allows a shorter hospital stay at the expense of a higher risk of recurrence of symptoms. It could be used as an alternative to open surgery for the treatment of Zenker's diverticulum, especially in frail patients.

Summary: This study compared the efficacy and safety characteristics of endoscopic and microscopic stapes surgery based on current evidence. The results showed that both techniques had similar success rates, but the endoscopic approach was favored for post-operative pain and dysgeusia. Further high-quality studies are needed to adequately compare the two methods.

Summary: This study assessed the practice differences in colonoscopy and report quality between urban and rural referral sites. The findings showed that rural reports had more missing information compared to urban reports. Further research is needed to improve the quality of endoscopy reporting for patients regardless of the endoscopy location.

Summary: This study evaluated the management pathways, outcomes, and safety of using rigid endoscopy and flexible endoscopy for the treatment of impacted foreign bodies in the upper gastrointestinal tract in adults. It found that flexible endoscopy had a higher success rate and lower complication rate, making it the preferred treatment option when possible.

Summary: The fusion of fiber-optic imaging with supervised deep learning has seen significant development in recent years, enabling high-quality imaging of difficult-to-reach areas. However, the requirement for paired collection of input objects and fiber outputs limits the potential of fiber-optic imaging. The use of unsupervised image reconstruction, based on transverse Anderson localization in disordered fibers, offers a new solution. In this study, unsupervised full-color imaging with cellular resolution was successfully demonstrated through a meter-long disordered fiber in both transmission and reflection modes. Two stages of unsupervised image reconstruction, involving pixel-wise standardization and fine detail recovery through a generative adversarial network, were employed. This approach allows for flexible calibration under various conditions without the need for paired images.

Summary: This research proposes an integrated light-field endoscope that enables 3D morphology observation with cellular-level resolution from a single-frame data record. By using a customized GRIN lens array as an objective lens, spatio-angular information from the object space can be directly captured and consistent spatial measurements can be maintained. The 3D morphology of a sample can be reconstructed by decoupling the spatio-angular information and performing a deconvolution operation. The system has a lateral resolution of about 15 to 40 μm and an axial resolution of 100 to 200 μm over an axial operating range of 10 mm.
