Pascal's law is used in which technique of hernia repair?: (A) Lichtenstein mesh repair, (B) Stoppa's preperitoneal repair, (C) Bassini's repair, (D) Darning repair
Answer is B. Stoppa's preperitoneal repair In Stoppa's preperitoneal repair, the expanding intra-abdominal pressure holds the mesh in place without suture fixation.
