Background: Robotic Rives-Stoppa ventral hernia repair (rRS-VHR) is a minimally invasive technique that incorporates extraperitoneal mesh placement, using either transabdominal or totally extraperitoneal access. An understanding of its learning curve and technical challenges may guide and encourage its adoption. We aim at evaluating the rRS-VHR learning curve based on operative times while accounting for adverse outcomes. Materials and Methods: We conducted a retrospective analysis of patients undergoing rRS repair for centrally located ventral and incisional hernias. A single surgeon operative time-based cumulative sum (CUSUM) analysis learning curve was created, and a composite outcome was used for risk-adjusted CUSUM (RA-CUSUM). Results: Eighty-one patients undergoing rRS-VHR were included. A learning curve was created by using skin-to-skin times. Accordingly, patients were grouped into three phases. The mean skin-to-skin time was 72.2 minutes, and there was a significant decrease in skin-to-skin times throughout the learning curve (Phase-I: 86.4 minutes versus Phase-III: 63.8 minutes; P = .001), with a gradual decrease after 29 cases. Eleven patients experienced adverse composite outcomes, which were used to create a RA-CUSUM graph. Results showed the highest adverse outcome rates in Phase-II, with a gradual decrease in risk-adjusted operative times after 51 cases. Conclusions: Consistently decreasing operative times and adverse outcome rates in rRS-VHR was observed after the completion of 29 and 51 cases, respectively. Future studies that provide group learning curves for this procedure can deliver more generalizable results in terms of its performance rates. [ABSTRACT FROM AUTHOR]

Background: Demographic disparities have been described for survival after thyroid cancer surgery using national registries and databases. At the institution level, we hypothesized that assessing survival after thyroid cancer surgery in a long-term cohort with diverse gender and racial groups would reveal disparities in survival. Methods: We examined medical records of patients with papillary or follicular thyroid cancer undergoing thyroidectomy, lobectomy, and other surgical procedures from 1971 to 2016 at a tertiary referral center. We obtained information on demographics, cancer stage, procedure, and radioactive iodine (RAI). We measured survival using Kaplan-Meier estimates and Cox proportional hazards models. Results: A total of 1440 (91%) patients with papillary cancer and 144 (9%) patients with follicular thyroid cancer underwent total thyroidectomy (1297, 82%), lobectomy (261, 16.5%), and other surgical procedures (26, 1.5%). Most patients (1131, 71%) were woman, and 909 (57%) were older than 45 years. Race/ethnicity included 805 (51%) white, 161 (10%) African Americans, and 618 (39%) other race/ethnicities. Both 10- and 20-year survival rates in nonwhite males were worse compared with nonwhite females (P <.0001). After controlling for age, cancer type, stage, surgical procedure, RAI, and year of surgery, nonwhite males had a higher mortality risk compared with nonwhite females (P =.0376, confidence interval (CI): 1.03-2.43), white males (P <.0001, CI: 1.88-6.54), and white females (P <.0001, CI: 3.31-9.90). Conclusions: Our diverse cohort demonstrates significant gender and racial disparities in survival after thyroid cancer surgery. To improve health outcomes and reduce health disparities among nonwhite males, interventions and long-term care management should target potentially modifiable causes of worse outcomes in this group.
