Bacteria can develop resistance to antibiotics, but little is known about their ability to increase resistance to chemical disinfectants. This study randomly sampled 3 automated endoscope reprocessors in the United States using aldehydes for endoscope disinfection. Bacterial contamination was found after disinfection in all automated endoscope reprocessors, and some mycobacteria isolates demonstrated significant resistance to glutaraldehyde and ortho-phthaldehyde disinfectants. Bacteria can survive aldehyde-based disinfection and may pose a cross-contamination risk to patients.

Robotic Laparoscopy and Endoscopy Cooperative Surgery for Primary Appendiceal Mucinous Carcinoma Masquerading as Bladder Cancer: A Case Report.
Asian J Endosc Surg
January 2025
Department of Surgery, Graduate School of Medicine, Kyoto University, Kyoto, Japan.
Bladder invasion by appendiceal cancer resulting in a vesico-appendiceal fistula is an uncommon occurrence. Both radical tumor removal and functional preservation of the bladder are desirable in the surgical treatment of this disease, and there are few reports on detailed surgical methods. Here, we describe a case of primary appendiceal mucinous carcinoma with bladder invasion treated with robotic laparoscopy and endoscopy cooperative surgery (RECS).

New procedures like the robotic approach require proficiency to ensure patient safety and satisfactory functional results. Hiatal hernia surgery serves as a suitable training procedure for upper gastrointestinal tract surgeons transitioning to the robotic approach. This study aims to evaluate the outcomes of implementing the robotic approach in hiatal hernia surgery at a tertiary hospital and to assess the associated learning curve.

Department of Anesthesiology, Zhujiang Hospital of Southern Medical University, Guangdong, 510000, China.
This study investigated the impact of an improved body positioning on the effectiveness of EDGE MP1000 robot-assisted laparoscopic partial nephrectomy. We compared clinical data from 39 patients who underwent the procedure at Zhujiang Hospital of Southern Medical University between November 2023 and May 2024. The control group (18 patients) received conventional positioning, while the experimental group (21 patients) received precise positioning, which included patient assessments, optimized positioning techniques, and enhanced nursing measures.

Faculty of Information Science and Technology, Hokkaido University, Sapporo, Japan.
Background: The automated classification of Helicobacter pylori infection status is gaining attention, distinguishing among uninfected (no history of H. pylori infection), current infection, and post-eradication. However, this classification has relatively low performance, primarily due to the intricate nature of the task.
