Dental implant placement performed for two patients with maxillary sinus floor pneumatization

Asymmetry in the size and shape of the sinus is common. Placing dental implants with maxillary sinus floor pneumatization can be challenging. Implant placement is rarely difficult in the anterior maxilla due to insufficient bone volume below the maxillary sinus.The indications and methodology of implant treatment for patients are dependent on the planning of endosseous implant treatment in the esthetic zone with implant therapy and should be based on careful diagnosis.Knowledge and understanding of maxillary sinus floor pneumatization is important to achieve an accurate diagnosis and realize appropriate treatment and management

Outcomes of Endoscopic Intervention Using Over-the-Scope Clips for Anastomotic Leakage Involving Secondary Fistula after Gastrointestinal Surgery: A Japanese Multicenter Case Series

Background: The over-the-scope clip (OTSC) is a highly effective clipping device for refractory gastrointestinal disease. However, Japanese data from multicenter studies for anastomotic leakage (AL) involving a secondary fistula after gastrointestinal surgery are lacking. Therefore, this study evaluated the efficacy and safety of OTSC placement in Japanese patients with such conditions. Methods: We retrospectively collected data from 28 consecutive patients from five institutions who underwent OTSC-mediated closure for AL between July 2017 and July 2020. Results: The AL and fistula were located in the esophagus (3.6%, n = 1), stomach (10.7%, n = 3), small intestine (7.1%, n = 2), colon (25.0%, n = 7), and rectum (53.6%, n = 15). The technical success, clinical success, and complication rates were 92.9% (26/28), 71.4% (20/28), and 0% (0/28), respectively. An age of 7 days (84.2%), and the use of simple suction (78.9%) and anchor forceps (80.0%) were associated with higher clinical success rates. Conclusion: OTSC placement is a useful therapeutic option for AL after gastrointestinal surgery
