Comparison of mid-term results and surgical technique in the robotic repair of lateral incisional hernias

42nd Annual European Hernia Society Congress, Barcelona, İspanya, 28 - 29 Mayıs 2020, cilt.24, ss.13-14, (Özet Bildiri)

Background: There is very little evidence available surrounding

lateral incisional hernias (LIH), and so, optimal repair methods have

not yet been established.

Objective: We aim to compare peri-operative and mid-term outcomes

of patients who underwent robotic LIH repair utilizing three separate

techniques.

Methods: Patients were grouped as intraperitoneal onlay (IPOM),

transabdominal preperitoneal (TAPP) or retromuscular (RM). Pre-,

intra-, post-operative variables were compared. Postoperative complications

were reviewed according to the Clavien-Dindo

classification, Comprehensive complication index (CCI ) scores, and

surgical site events (SSEs) including surgical site occurrences (SSOs)

and surgical site infections (SSIs). Chi square test or Fisher’s exact

test was used for categorical variables. One-way ANOVA test or

Kruskal–Wallis test was used for continuous variables as appropriate.

123

Results: A total of 26 patients were included in the study; 5 (19.2%)

underwent IPOM, 8 (30.8%) underwent TAPP, and 13 (50%)

underwent RM repair. Although there were no differences regarding

hernia defect size, a larger mesh size, as well as a greater mesh

overlap, was achieved in the RM group as compared to the IPOM and

TAPP groups (p\0.05). Additionally, RM repair allowed for a

higher mesh-to defect ratio than the recommended ratio of 16:1.

There were no differences between groups in terms of operative times

and postoperative outcomes, including SSEs, Clavien-Dindo grades,

and CCI scores.

Conclusion: Robotic IPOM, TAPP, and RM repair did not differ in

terms of mid-term postoperative outcomes. However, robotic RM

repair allows for significantly larger mesh size and mesh overlap, as

well as a higher mesh-to-defect ratio.
