TORS< oropharyngeal carcinoma
Dr. Anand Subash, HCG Bangalore, has had this article presented in the Head and Neck Journal ( 24 December 2020): Selective embolization of lingual artery in transoral robotic surgery for the management of recurrent base of tongue carcinomas Here is an excerpt from the Abstract: Background: The incidence of oropharyngeal carcinoma has been on the rise in recent decades. About 30% of patients who undergo definitive chemoradiation as the initial treatment present with residual/recurrent disease. In such a situation, surgical salvage either in the form of traditional open surgery or transoral robotic surgery (TORS) remains a viable treatment option. However, the extensive vascular supply of the posterior tongue and tonsillar bed increases the risk of perioperative bleeding, which is a key concern. The article describes the technique of selective pre‐operative embolization to reduce the risk of perioperative bleeding and enumerate its advantages in providing a bloodless field during surgery.

RAPN
Objective: To analyze the outcomes of patients in whom cortical (outer) renorrhaphy (CR) was omitted during robotic partial nephrectomy (RPN). Methods: We analyzed 1453 patients undergoing RPN, from 2006 to 2018, within a large multi-institutional database. Patients having surgery for bilateral tumors (n = 73) were excluded. CR and no-CR groups were compared in terms of operative and ischemia time, estimated blood loss (EBL), complications, surgical margins, hospital stay, change in estimated glomerular filtration rate (eGFR), and need of angioembolization. Inverse probability of treatment weighting with Firth correction for center code was performed to account for selection bias.

RAPN / Machine learning
The Vattikuti Collective Quality Initiative database was used for a study of Machine Learning (ML) being used to help predict outcomes for partial nephrectomy patients. 'Predicting intra‐operative and postoperative consequential events using machine‐learning techniques in patients undergoing robot‐assisted partial nephrectomy: a Vattikuti Collective Quality Initiative database study' has been published in the April 21 issue of the BJUI Journal.

TORS
Former Vattikuti Fellow Dr. Karan Gupta and his Mentor Surgeon Dr. Surender Dabas have collaborated to produce an article for the European Journal of Surgical Oncology. Here is the abstract: To report long-term oncological and functional outcome of Transoral Robotic Surgery escalated treatment including radiotherapy or chemoradiotherapy for Stage III-IV HPV negative oropharyngeal malignancies. METHOD: From March 2013 to September 2015, 153 patients with oropharyngeal carcinoma were included in the study. Patients were evaluated for disease free survival, overall survival and post-treatment functional outcomes. RESULTS: 153 patients (96 males and 57 females) underwent TORS for oropharyngeal carcinoma. 142 patients on final histopathology had stage III and IV disease and received adjuvant treatment based on final histopathology. One hundred and sixteen (81.7%) patients were disease free on average follow-up of 48 months with an overall survival of 91.5% at mean follow-up of 48 months. CONCLUSION: TORS can be used to intensify treatment of Stage III/IV oropharyngeal carcinoma and avoid early and late toxicities due to higher doses of upfront RT/CTRT and achieve better oncological outcome.

robotic urethrovesical anastomosis (simulated)
A recent study produced by our friends at the Vattikuti Institute of Robotic Surgery, King’s College London, has been honored as the BJUI Article of the week (for 12-19-2018). Cognitive training for technical and non‐technical skills in robotic surgery: a randomised controlled trial, discusses the results of a study comparing novice surgeons which were placed into groups to receive motor imagery (MI) for technical skill and non‐technical skill (NTS) training in minimally invasive surgery.

RARP
From Journal of laparoendoscopic & advanced surgical techniques / PubMed: We aimed to investigate the effects of intra-abdominal pressure and steep Trendelenburg position on the intrarenal vascular parameters and estimated glomerular filtration rate (eGFR) in the first 24 hours of robot-assisted radical prostatectomy (RARP) surgery.

robot-assisted kidney autotransplantation (RAKAT)
From European Urology" Abstract Background Kidney autotransplantation (KAT) is the ultimate way to salvage kidneys with complex renovascular, ureteral, or malignant pathologies that are not amenable to in situ reconstruction. A minimally invasive approach could broaden its adoption.

Prostate Cancer Therapy
From European Urology: Abstract BACKGROUND: The gap in prostate cancer (PCa) survival between Blacks and Whites has widened over the past decade. Investigators hypothesize that this disparity may be partially attributable to differences in rates of definitive therapy between races. OBJECTIVE: To examine facility level variation in the use of definitive therapy among Black and White men for localized PCa.

RAPN transperitoneal/retroperitoneal
From PubMed: Abstract OBJECTIVES: To evaluate retroperitoneal robot-assisted partial nephrectomy (RAPN) against transperitoneal approach in a multi-institutional prospective database, after accounting for potential selection bias that may affect this comparison. PATIENTS AND METHODS: Post-hoc analysis of the prospective arm of the Vattikuti Collective Quality Initiative database from 2014-2018. Six hundred and ninety consecutive patients underwent RAPN by 22 surgeons at 14 centers in nine countries. Patients who had surgery at centers not performing retroperitoneal approach (n=197) were excluded. Inverse probability of treatment weighting was done to account for potential selection bias by adjusting for age, gender, body mass index, comorbidities, side of surgery, location/size/complexity of tumor, renal function, American Society of Anesthesiologists score, and year of surgery. Operative and perioperative outcomes were compared between weighted transperitoneal and retroperitoneal cohorts.
