The clinical anatomy of the triangle of Petit

Abstract

We hope these data will help prediction of which patients are at greater risk of herniation through the TP.

Comparative Study of Bupivacaine 0.25% Versus Ropivacaine 0.5% in Transversus Abdominis Plane Block for Postoperative Analgesia in Lower Abdominal Surgeries : A Randomised Controlled Trial

“…Although it is possible to ultrasonically visualize the 3 muscle layers of the abdominal wall, there is variation in these muscle layers that can restrict the use of ultrasound over the triangle of Petit. 13 As a result, the needle insertion point as described in the ultrasound studies, which is dependent on the adequate identification of the 3 muscle layers, can vary.…”

Morphometric study of the triangle of Petit in human fetuses

“…[11][12][13] Lower lumbar hernias may be both congenital and acquired, constituting 20% and 80% of cases, respectively. 4,5,10,11,14 Congenital defects of the posterior abdominal wall are the most common reasons for the lower lumbar hernias in children. 15,16 In turn, acquired lower lumbar hernias are divisible into primary and secondary types, the former resulting from an excessive tonus of abdominal musculature, e.g., in obese elderly people, and the latter being a consequence of damage to the abdominal muscles and resulting in scar formation.…”

“…[6][7][8][9] To date, autopsy material of adult individuals only has been used for the geometrical analysis of Petit's triangle. 6,7,10 Therefore, this is the first report in the professional literature to present a numerical analysis of Petit's triangle in human fetuses.…”

Addition of transversus abdominis plane block to patient controlled analgesia for laparoscopic high anterior resection improves analgesia, reduces opioid requirement and expedites recovery of bowel function

“…However, the triangle is highly variable in site and presence. 19,47,48 Consequently, the ultrasonography guided technique was described. 49 Other technical variants include a 'multiple injection' Figure 6 Mean length of hospital stay technique and continuous infusion via a subcutaneous catheter.…”
