Summary: This study evaluated the feasibility, safety, and outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomy performed at three institutions in Italy. The results showed that vNOTES had shorter operation times, lower postoperative pain levels, and lower complication rates. This suggests that vNOTES is a feasible alternative to conventional surgery.

Summary: This article introduces a novel robotic instrument that can assist in Natural Orifice Transluminal Endoscopic Surgery (NOTES). The instrument has a diameter of 6.5 mm and 7 degrees of freedom (DOF). It utilizes helical springs with high torsional rigidity for three continuum elastic joints, and patterned concentric tubes to change the stiffness of the force transmission structure. Analytical solutions for inverse kinematics are obtained based on the arrangement of coupled joints. A disk-elastomer model is established to simplify the derivation of kinematics, and the relationship between cable slack and joint parameters is derived. Experimental results verify the trajectory tracking accuracy, bending accuracy, and variable stiffness ability of the proposed instrument.

Summary: A new mini-tubular port is designed for endoscopic intraventricular surgery, combining intra- and extra-endoscopic techniques. This new methodology improves bleeding control and allows for more efficient execution of complicated techniques. The use of the mini-tubular port effectively controls bleeding and improves patient prognosis.

Summary: In this study, 107 patients with postsurgical portal vein thrombosis were retrospectively analyzed, revealing that the type of surgery, degree of thrombosis occlusion, and type of anticoagulant used significantly influenced the outcomes. Failure to achieve complete radiographic resolution of portal vein thrombosis was associated with a greater risk of developing clinical portal hypertension in the future.

Summary: This study retrospectively analyzed the clinical data of 37 patients who underwent robot-assisted total hysterectomy by vNOTES. The results showed the feasibility and safety of this procedure, with reduced surgical trauma, aesthetic incision, decreased pain, and shorter duration of postoperative exhaust time and hospital stay, contributing to accelerated postoperative rehabilitation.

Summary: This study compared patient characteristics, operative details, and postoperative outcomes between single-port access (SPA) laparoscopic surgery and vaginal natural orifice transluminal endoscopic surgery (vNOTES). The results showed that the early operative outcomes of vNOTES were comparable to SPA, with shorter operative time and lower postoperative pain scores.

Summary: This study compared the surgical outcomes of gasless and traditional robot-assisted transvaginal natural orifice transluminal endoscopic surgery (GR-vNOTES vs. TR-vNOTES) in hysterectomy. The results showed that both techniques had similar operative outcomes and no complications. GR-vNOTES is a feasible and safe alternative to TR-vNOTES in hysterectomy.

Summary: The study aimed to evaluate the efficacy and safety of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) in the treatment of female infertility. The results showed that compared to the LESS group, the vNOTES group had a shorter postoperative bowel movement time and less pain at 4 and 12 hours. vNOTES represents a new, less invasive approach for infertility diagnosis and treatment that is particularly suitable for women who have special esthetic requirements, and it may be an ideal choice for scarless infertility surgery.

Summary: Middle Eastern women in the study generally hold a neutral view towards abdominal and gynecological procedures via vaginal route, with uncertainty regarding the impact on sexual function. However, they are more inclined towards vNOTES if proven to be as safe and effective as laparoscopic surgery. The gender of the surgeon does not seem to influence the participants' perspectives on undergoing vNOTES.

Summary: Micronutrients are essential for healthy metabolic function, wound healing, and prevention of diseases and infections. However, there is limited research on micronutrient supplementation in surgical patients. Current guidelines mainly focus on macronutrients and may not address subclinical micronutrient deficiencies. Further research is urgently needed to explore the potential benefits of micronutrition for postoperative recovery and to guide optimal clinical practice.

Summary: This study aims to identify the causes of unplanned return to theatre (URTT) in rural general surgical patients. The study found that the rates of URTT in South Australian rural hospitals are lower compared to overseas hospitals. The wide range of surgeries performed in rural centers highlights the need for tailored training programs for rural surgical trainees to manage potential complications.

Summary: Communication between doctors and patients is crucial for establishing a strong doctor-patient relationship. Patient-focused interventions, such as educational materials and decision aids, have shown promise in improving communication and increasing patient knowledge. However, more research is needed to fully evaluate the impact of these interventions.

Summary: This study investigates the variation in polyp incidence in different age groups, gender, and indications for colonoscopy. The results show differences in adenoma and serrated polyp detection rates based on age, gender, and indication for colonoscopy. The findings can contribute to the development of key performance indicators in colonoscopy.
