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.

SLN mapping, Endometriosis

Vattikuti Network Surgeon Dr. Anupama Rajanbabu, from the Department of Gynecologic Oncology, Amrita Institute of Medical Sciences, has been published in the European Journal of Obstetrics & Gynecology and Reproductive Biology. Her Objective states: "Sentinel node mapping is emerging as the alternative to lymphadenectomy in endometrial cancer. The objective of our study is to validate of the sentinel node mapping surgical algorithm and also to compare the performance of the algorithm against endometrial cancer risk subtypes."

RAPN, multiple renal tumors

Published in: VideourologyVol. 32, No. 1, in video form. From the Mary Ann Liebert, Inc. publishers website: Abstract of video program: Patients with multiple renal tumors may have a higher chance of metachronous contralateral renal tumors. Owing to this, efforts must be made to utilize nephron sparing surgery in these cases, wherever possible. Longer ischemia times are expected because of resection and reconstruction of multiple defects. The outcomes of robot-assisted partial nephrectomy (RAPN) for this indication have previously been reported to be comparable with solitary tumors. However, other series have shown an increased complication rate. The three goals of surgery are to remove all the tumor with acceptable ischemia time and low complication rate. This video shows the technique and outcomes of RAPN for multiple tumors in a single operative session in a multi-institutional setting.

Kidney Transplant, living & deceases donors

Background The Internet has extensive resources for kidney transplantation recipients. Half of the population reads below a seventh-grade level. Previous studies showed that living donor recipients have higher health literacy rates compared with deceased donor recipients. There has been no study comparing the readability of online living donor recipient materials versus deceased donor recipient materials. Methods Analysis was performed using eight readability scales on the top 10 websites for live donor and deceased donor kidney transplantation. Analysis was performed through the Readability Studio Software. USA reading grade level was determined for each site. Results Overall, the mean reading level for the living donor materials was 12.54 (range 9.2–17) and for the deceased donor materials, 12.87 (range 8.7–17, P = 0.73), corresponding to a university level. None of the sites met the seventh-grade level recommended by the National Institute of Health. Conclusions The readability of online materials remains too high for the corresponding health literacy rates among patients requiring kidney transplantation. Specifically, the lower health literacy rates among deceased donor recipients does not mirror the readability of online materials provided at a university level. This may affect decision-making, contributing to a smaller proportion of patients of a lower socioeconomic status and those with poor English language skills pursuing live donor organs. donor, health literacy, Internet, kidney, readability, transplant Topic: renal transplantation decision making internet living donors socioeconomic factors software kidney health literacy readability weight measurement scales donors Issue Section: Original Article
