Emergency robotic-assisted repair in an elderly patient with strangulated hernia and active influenza A infection: A case report

Figure 1 Incarcerated inguinal hernia with sigmoid colon content. A: Incarcerated sigmoid colon within the inguinal hernia sac, with a thin, stretched peritoneal band at the neck of the defect; B: Close-up of the herniated sigmoid colon at the inguinal defect, with the constricting peritoneal band and surrounding adhesions exposed; C: Sigmoid colon after release from the hernia sac, showing reactive hyperaemia but intact serosa; D: Final view of the inguinal defect after reduction of the sigmoid colon, with protruding preperitoneal/hernia fat and the divided peritoneal band.

Figure 2 Preperitoneal mesh placement. A macroporous non-absorbable polypropylene mesh (Prolene) is spread flat over the hernia defect to cover the inguinal ring tension-free while a suture is placed through it.
