Robotic-assisted repair of complex ventral hernia: can it pay off?

Pressure on health care providers is growing due to capping of remuneration for medical services in most Western European countries. We wanted to investigate, if robotic-assisted ventral hernia repair is reasonable from an economic point of view in our setting. Patients undergoing open or robotic-assisted repair for complex abdominal wall hernia using a Transversus Abdominis Release (TAR) between September 2017 and January 2019 were included. Procedure-related costs were calculated exact to the minute and cost unit accounting for the postoperative in-patient stay was done. Abdominal wall reconstruction using the TAR-technique was done in a total of 26 (10 female) patients via an open (n = 10) or robotic-assisted (n = 16) approach. No significant difference was seen in regard to age, BMI and ASA scores between subgroups. Time for operation was longer (253.5 vs 211.5 min; p = 0.0322), while postoperative hospital stay was shorter for patients operated with a robotic-assisted approach (4.5 vs 12.5 days; p < 0.005). Procedure-related costs were 2.7-fold higher when a robotic-assisted reconstruction was done (EUR 5397 vs. 1989), while total costs for in-patient stay were about 60% lower (EUR 2715 vs 6663). Currently, revenues by national insurance account for a total of EUR 9577 leading to a profit of EUR 1465 and 925 for the robotic-assisted and open myofascial release, respectively. In addition, 30-day re-admission rate was in favor of the robotic-assisted approach as well (6.3% vs 20%). From an economic point of view, robotic-assisted TAR for complex ventral hernia repair is a viable option in our setting. Higher procedure-related costs are offset by a significant shorter hospital stay. The economic advantage goes along with improvement in outcome of patients.

Standard laparoscopic versus robotic retromuscular ventral hernia repair.

BACKGROUND: Laparoscopic ventral hernia repair (LVHR) demonstrates comparable recurrence rates, but lower incidence of surgical site infection (SSI) than open repair. Delayed complications can occur with intraperitoneal mesh, particularly if a subsequent abdominal operation is required, potentially resulting in bowel injury. Robotic retromuscular ventral hernia repair (RRVHR) allows abdominal wall reconstruction (AWR) and extraperitoneal mesh placement previously only possible with open repair, with the wound morbidity of LVHR. METHODS: All LVHR and RRVHR performed in our institution between June 2013 and May 2015 contained in the Americas Hernia Society Quality Collaborative database were analyzed. Continuous bivariate analysis was performed with Student's t test. Continuous nonparametric data were compared with Chi-squared test, or Fisher's exact for small sample sizes. p values <0.05 were considered significant. RESULTS: We compared 103 LVHR with 53 RRVHR. LVHR patients were older (60.2 vs. 52.9 years; p = 0.001), but demographics were otherwise similar between groups. Hernia width was similar (6.9 vs. 6.5 cm, p = 0.508). Fascial closure was achieved more often with RRVHR (96.2 vs. 50.5 %; p < 0.001) and aided by myofascial release in 43.4 %. Mesh was placed in an intraperitoneal position in 90.3 % of LVHR and extraperitoneal in 96.2 % of RRVHR. RRVHR operative time was longer (245 vs. 122 min, p < 0.001). Narcotic requirement was similar between LVHR and RRVHR (1.8 vs. 1.4 morphine equivalents/h; p = 0.176). Seroma was more common after RRVHR (47.2 vs. 16.5 %, p < 0.001), but SSI was similar (3.8 vs. 1 %, p = 0.592). Median length of stay was shorter after RRVHR (1 vs. 2 days, p = 0.004). Direct hospital cost was similar (LVHR $13,943 vs. RRVHR $19,532; p = 0.07). CONCLUSION: RRVHR enables true AWR, with myofascial release to offset tension for midline fascial closure, and obviates the need for intraperitoneal mesh. Perioperative morbidity of RRVHR is comparable to LVHR, with shorter length of stay despite a longer operative time and extensive tissue dissection.

[Organizational and surgical-technical aspects of the service of abdominal hernioplasty]. / Aspetti organizzativi e tecnico-chirurgici di un servizio di chirurgia delle ernie addominali.

The authors guided by the experience matured from 1/01/94 to 30/06/97 (435 abdominal hernioplasties performed, mainly inguinal and femoral) illustrate the organizational formalities and the technical aspects of a Hernia Surgery Service. In particular, they highlight the advantages of the routine use of local anaesthesia and of tension-free techniques, carried out on a day surgery rule (immediate rehabilitation, greater facilitation to elective surgery, access to the elderly at high anaesthetic risk). Eventually, they emphasize the remarkable reduction of sanitary costs and the outstanding social, practical and didactic value of such Hernia Centers.

[Possibilities in the surgical treatment of simple abdominal hernias at polyclinics]. / Vozmozhnosti operativnogo lecheniia prostykh gryzh zhivota v usloviiakh polikliniki.

The article deals with questions of organization and treatment of patients with hernias of the abdomen under conditions of polyclinic. 27 operations were performed on 23 patients for the hernia disease. There were no complications. The operations were endured well and the patients returned to their work. The average time of disability was 24 days.
