Perioperative Nursing Role in Robotic Surgery: An Integrative Review

PURPOSE

Robotic surgery is an increasingly popular approach across surgical specialties in several countries. Nurses embedded in this highly-technological environment, however, could excessively center their attention to the robot, deviating their focus from the patient. The Perioperative Patient Focused Model is proposed as a theoretical framework to guide nursing perioperative care towards a patient-centered approach based upon 4 dimensions: Health System, Safety, Behavioral Responses and Physiological Responses. This review aimed to understand the role of perioperative nursing in robotic surgery according to the Perioperative Patient Focused Model.

DESIGN

An integrative review.

METHODS

The Whittemore and Knafl methodology guided this review. The following databases were searched: PubMed, Cochrane Library, ProQuest, Scielo, and LILACS. The keywords used were "Robotic Surgical Procedures" and "Nursing" and their equivalents in Spanish, Portuguese, and French, using the Boolean operator "AND," within the time frame of 2010-2021.

FINDINGS

A total of 1,695 articles were retrieved, of which 26 were retained for the final analysis. The majority (n = 17) were written in English, with a level of evidence between 4 and 5. The main actions performed by nursing professionals were retrieved in the Health Systems, Safety, and Behavioral Responses dimensions, focusing on the intraoperative and postoperative period. However, most of the patient's responses were presented in the postoperative stage, even after discharge. Encompassing these findings, a theoretical framework is proposed.

CONCLUSIONS

Nursing professional duties are diverse within the course of robotic surgery. It is necessary to expand the Perioperative Nursing specialty towards an extended care, encompassing even the community settings.

Robotic-assisted vertical sleeve gastrectomy in adolescents: Do BMI limits apply?

BACKGROUND

Robotic-assisted vertical sleeve gastrectomy (VSG) in adolescent patients has been shown to have comparable outcomes to laparoscopic VSG. Recent data suggests that metabolic and bariatric surgery (performed using robotic and laparoscopic techniques) in patients with BMI ≥ 50 kg/m² have a higher risk of adverse events compared to those with BMI < 50 kg/m². The aim of this study was to compare the outcomes of robotic-assisted VSG in adolescents with a BMI above and below 50 kg/m².

METHODS

A retrospective analysis of all adolescents undergoing robotic-assisted VSG between January 2014 and December 2020. Subjects were categorized based on preoperative BMI; Group 1 (BMI < 50 kg/m²) or Group 2 (BMI ≥ 50 kg/m²). Data collection included patient demographics, preoperative BMI, total operative time, access time (i.e., total time for port-placement), 30 day complications, and 30 day hospital readmissions. Analysis was performed using chi-square, Fisher's Exact, and student t-test.

RESULTS

Total of 115 subjects (Group 1 N = 64 and Group 2 N = 51) were included. No differences in age or ethnicity were detected; however, Group 2 had a higher percentage of male patients (27.5% vs. 4.7%, respectively, p = 0.001). Mean operative times (Group 1 = 122.2 min vs. Group 2 = 121.6 min) and access times (Group 1 = 19.1 min vs. Group 2 = 19.7 min) were similar between groups. Thirty day complication rates were similar between groups (p = 0.133); however, there was a higher rate of hospital readmission in Group 1.

CONCLUSION

While recent data demonstrate an increased likelihood of adverse events occurring among patients with BMI ≥ 50 kg/m² undergoing robotic surgery, we observed no differences in intraoperative or early postoperative outcomes based on BMI in this robotic-assisted pediatric cohort.

Robotic and laparoscopic Roux-en-Y gastric bypass after learning curve: 30-day and 12-month outcomes

This study compares laparoscopic RYGB (L-RYGB) and robotic RYGB (R-RYGB) performed by the same team after the learning curve in both approaches. A retrospective cohort study was done, and the surgical outcome was analyzed in 30 days and 12 months for patients with similar characteristics and an equal number of cases in each group (233 cases). Four hundred and sixty-six patients were included in this study. Mean age was 46.8 ± 8.3 years and 2/3 were women. R-RYGB presented a longer operative time (150.7 versus 135.4 min; p < 0.001) with no differences in the length of hospital stay. The main 30-day complications were G-J stricture, leakage, and intraluminal bleeding. The reoperation rate was 1.6% by leakage (G-J anastomosis) and was higher in R-RYGB (2.1 versus 0.4; p = 0.108). The multivariate analysis identified that L-RYGB was the factor independently associated with a LOS longer than 2 days (odds ratio: 4.7, 95% CI: 2.6-8.2, p value < 0.001). At the FU time (12 months), no differences between the groups were found. The outcomes between the groups after the learning curve did not present differences in terms of 30 days and 12 months of FU when same preoperative characteristics and an equal number of cases in each group are considered. L-RYGB was the unique independent factor associated with long LOS.

Five Year Trends in the Utilization of Robotic Bariatric Surgery Procedures, United States 2015-2019

PURPOSE

Robotic approaches have been steadily replacing laparoscopic approaches in metabolic and bariatric surgeries (MBS); however, their superiority has not been rigorously evaluated. The main goal of the study was to evaluate the 5-year utilization trends of robotic MBS and to compare to laparoscopic outcomes.

METHODS

Retrospective analysis of 2015-2019 MBSAQIP data. Kruskal-Wallis test/Wilcoxon and Fisher's exact/chi-square were used to compare continuous and categorical variables, respectively. Generalized linear models were used to compare surgery outcomes.

RESULTS

The use of robotic MBS increased from 6.2% in 2015 to 13.5% in 2019 (N= 775,258). Robotic MBS patients had significantly higher age, BMI, and likelihood of 12 diseases compared to laparoscopic patients. After adjustment, robotic MBS patients showed higher 30-day interventions and 30-day readmissions alongside longer surgery time (26-38 min).

CONCLUSION

Robotic MBS shows higher intervention and readmission even after controlling for cofounding variables.

Laparoscopic sleeve gastrectomy in patients with complex abdominal wall hernias

BACKGROUND

Patients with severe obesity and complex abdominal wall hernias (CAWH) present a challenging clinical dilemma. Their body mass index (BMI) is often prohibitive of successful ventral hernia repair (VHR) and the CAWH presents technical challenges when pursuing bariatric surgery. Our hernia center policy is to refer patients with severe obesity for evaluation with the surgical weight loss program. This study describes outcomes of laparoscopic sleeve gastrectomy (LSG) in patients with both severe obesity and CAWH.

METHODS

A retrospective analysis was performed on data prospectively collected between 2014 and 2020. CAWH patients referred for and undergoing LSG were included. Revisional bariatric surgery patients were excluded. The dataset was augmented with operative time, BMI changes, length of stay (LOS), hernia characteristics, postoperative complications, time from referral to weight loss surgery, and time from LSG to VHR.

RESULTS

Twenty patients (10 males, mean age 54.3 years) met inclusion criteria. Mean BMI at LSG was 45.6 ± 6.1 kg/m². Mean hernia area was 494.9 ± 221.2 cm² and 90% had hernia extension into the subxiphoid and/or epigastric regions. Mean time from bariatric referral to LSG was 10.5 ± 5.4 months. Mean LSG operative time was 121.2 ± 50.3 min, and mean LOS was 1.6 ± 0.8 days. One patient had postoperative bleeding necessitating laparoscopic re-exploration. There were no readmissions. Sixteen patients subsequently underwent VHR on average13.5 ± 11.7 months later and on average 22.6 ± 12.5 months after initial hernia consultation. Two patients had a hernia-related complication between the period of initial hernia consultation and ultimate repair. Mean BMI was 37.5 ± 7.5 kg/m² (mean 20.7 ± 12.3% decrease, p < 0.0001) at mean follow-up of 27.2 ± 17.2 months.

CONCLUSIONS

LSG can be performed successfully even in patients with CAWH. Outcomes do not appear to differ significantly from typical patients undergoing LSG. Further study with larger cohorts is warranted to better delineate complication rates in this population as well as to determine long-term outcomes.
