    Impact of Refractive Errors on Da Vinci SI Robotic System
    (SOC LAPAROENDOSCOPIC SURGEONS, 2020-01-01) Tuna, Mustafa Bilal; Kilavuzoglu, Ayse Ebru; Mourmouris, Panogiotis; Argun, Omer Burak; Doganca, Tunkut; Obek, Can; Ozisik, Ozan; Kural, Ali Riza
    Objective: To investigate the impact of refractive errors on binocular visual acuity while using the Da Vinci SI robotic system console. Methods: Eighty volunteers were examined on the Da Vinci SI robotic system console by using a near vision chart. Refractive errors, anisometropia status, and Fly Stereo Acuity Test scores were recorded. Spherical equivalent (SE) were calculated for all volunteers' right and left eyes. Visual acuity was assessed by the logarithm of the minimal angle of resolution (LogMAR) method. Binocular uncorrected and best corrected (with proper contact lens or glasses) LogMAR values of the subjects were recorded. The difference between these values (DiffLogMAR) are affected by different refractive errors. Results: In the myopia and/or astigmatism group, uncorrected SE was found to have significant impact on the DiffLogMAR (P < 0.001) and myopia greater than 1.75 diopter had significantly higher DiffLogMAR values (p < 0.05). Subjects with presbyopia had significantly higher DiffLogMAR values (p < 0.01), and we observed positive correlation between presbyopia and DiffLogMAR values (p = 0.33, p < 0.01). The cut off value of presbyopia that correlated the most with DiffLogMAR differences was found to be 1.25 diopter (P< 0.001). In 13 hypermetropic volunteers, we found significant correlation between hypermetropia value and DiffLogMAR (p > 0.7, p < 0.01). The statistical analysis between Fly test and SE revealed a significant impact of presbyopia and hypermetropia to the stereotactic view of the subject (p = -0.734, p < 0.05). Conclusion: Surgeons suffering from myopia greater than 1.75 diopter, presbyopia greater than 1.25 diopter (D), and hypermetropia regardless of grade must always perform robotic surgeries with the proper correction.

    Robotic mitral valve replacement
    (AME PUBLISHING COMPANY, 2022-01-01) Arslanhan, Gokhan; Senay, Sahin; Kocyigit, Muharrem; Gullu, Ahmet Umit; Alhan, Cem
    Background: This study evaluates the clinical outcome of patients with robotic mitral valve replacement (MVR).Methods: Between January 2010 and April 2022, 117 consecutive patients underwent robotic MVR with or without additional cardiac procedures. All procedures were completed by a single surgical team with Da Vinci Robotic Systems. Perioperative variables and early clinical outcomes were recorded.Results: Mean age and EuroScore II of the patients were 57.1 +/- 12.9 and 5.1 +/- 5.7, respectively. Isolated MVR was performed in 55 (47.0\%) patients and combined cardiac procedures were performed in 62 (53.0\%) patients. Additional procedures included: ablation for atrial fibrillation, tricuspid valve replacement, tricuspid valve repair, left atrial appendix ligation, patent foramen ovale closure, left atrial thrombectomy and septal myectomy for hypertrophic obstructive cardiomyopathy. Mean cardiopulmonary bypass time and cross clamp time were 143 +/- 54 and 93 +/- 37 minutes, respectively. Mean intensive care unit stay time was 26.5 +/- 26.0 hours. Postoperative stroke was observed in one (0.9\%) patient and new onset renal failure was observed in two (1.7\%) patients. Perioperative and postoperative early mortality was observed in three (2.6\%) patients, which was lower than expected.Conclusions: Robotic MVR is feasible and can be performed with good early postoperative outcomes. A majority of the patients require additional cardiac procedures.

    A simple method for occlusion of both venae cavae in total cardiopulmonary bypass for robotic surgery
    (OXFORD UNIV PRESS, 2012-01-01) Gullu, Ahmet Umit; Senay, Sahin; Kocyigit, Muharrem; Alhan, Cem
    We describe a novel surgical technique for occlusion of the superior and inferior venae cavae which allows opening of the right atrium safely during robotic cardiac surgery.

    Robotic-assisted beating heart surgery provides precise repair of periprosthetic mitral valvular leak
    (OXFORD UNIV PRESS, 2022-01-01) Kocyigit, Muharrem; Gullu, Ahmet Umit; Senay, Sahin; Alhan, Cem
    The prosthetic paravalvular leak is a rare but important complication following mitral valve replacement. Determining the location of the leak is almost always dependent on perioperative transoesophageal echocardiography and the considerable expertise of echo operators. Acoustic shadowing due to the prosthetic valve may create another important difficulty. In this report, we present a case with a paravalvular leak diagnosed 1 year after mitral valve replacement. Beating heart surgery and robotic 3D/high-resolution camera provided to localize the direct location of leak coherent with perioperative echocardiography and precise repair. The robotic approach prevented the potential complications of aortic cross-clamp and resternotomy. The paravalvular leak is one of the most important complications of mitral valve replacement surgery with a prevalence of 2-13\% {[}1, 2].

    Cosmetic Outcome of Robotic Surgery Compared to Laparoscopic Surgery for Benign Gynecologic Disease
    (SOC LAPAROENDOSCOPIC SURGEONS, 2022-01-01) Ozbasli, Esra; Takmaz, Ozguc; Albayrak, Nazli; Gungor, Mete
    Background and Objectives: This study was designed to compare patients who have undergone conventional laparoscopic surgery with those who undergone multiport robot-assisted laparoscopic surgery for benign gynecological diseases regarding cosmetic results, patient satisfaction, and quality of life. Methods: Sixty-four patients who underwent either robot-assisted or conventional laparoscopic surgery for benign gynecological diseases from July 1, 2019 to March 31, 2020 at Acibadem Mehmet Ali Aydinlar University Hospital were enrolled. Patients were evaluated using the Patient and Observer Scar Assessment Scale, visual analog scale for cosmetic satisfaction, body image questionnaire, and 12-item Short Form Survey six months postoperatively. Results: The median patient assessment scale and observer assessment scale (general) values were significantly higher in the robotic group than in the laparoscopic group. The mean body image questionnaire (cosmetic section) and visual analog scale values were significantly higher in the laparoscopic group than in the robotic group. No significant differences in body image scale, body image questionnaire 9-10, and 12-item Short Form Survey values were observed between the groups. The number of patients with previous surgical history was significantly higher in the laparoscopic group than in the robotic group. Conclusion: Although esthetic concerns are not a priority consideration when deciding an appropriate surgical method, the higher cosmetic satisfaction rate in the laparoscopic group than in the robotic group suggests that cosmetic results should be discussed with patients after evaluating other factors.
