Purpose: To evaluate the clinical efficacy and safety of a novel shape-memory Bi-hook device in facilitating antegrade stent implantation for canalicular laceration repair.
Methods: In this retrospective comparative study, 76 patients (76 eyes) with canalicular laceration were enrolled: 39 patients (39 eyes) underwent Bi-hook-assisted stent implantation (Bi-hook group) and 37 patients received conventional Ritleng stent intubation (control group). The Bi-hook device was fabricated using a thermally shaped 0.

Gastric perforation (GP) is characterized by full-thickness injury of the stomach wall, a severe and potentially life-threatening gastrointestinal disease. However, current treatment, including surgical sutures and endoscopic closure, faces limitations, achieving complete sealing of the perforation and favorable healing remains a great challenge and an acute clinical demand. Here, we report a hydrogel dry powder (PPCL@Mg) for the minimally invasive treatment of GP, which can be delivered to target perforation wounds by spraying via an endoscope, and rapidly absorbing interfacial water and spontaneously forming a hydrogel.

Background: This study aimed to compare a 3-dimensional (3D)-printed titanium cage with a polyetheretherketone (PEEK) cage in biportal endoscopic transforaminal lumbar interbody fusion (BETLIF) using a double cage construct, evaluate differences in fusion stability and subsidence between the 2 cage types, and analyze factors influencing subsidence.
Methods: We retrospectively examined 89 patients who underwent BETLIF using a double cage (3D-printed titanium, 48 levels; PEEK, 46 levels). Fusion status and subsidence were assessed using dynamic plain lateral lumbar spine radiographs and computed tomography images at 6 months and 1 year postoperatively.

Endoscopic stapedotomy offers a panoramic transcanal view of middle-ear structures while minimizing canal trauma. Reverse stapedotomy, in which the footplate fenestration precedes the removal of the stapes superstructure, may improve footplate stability and procedural safety. The use of CT-based three-dimensional (3D) virtual endoscopy for surgical planning in otosclerosis remains uncommon.
