Palmer's point
Pronunciation: PAHL-mers point
An anatomical landmark in the left upper quadrant used for safe initial laparoscopic access in bariatric surgery.
Full Definition
Palmer's point is located in the left subcostal region, approximately 3 cm below the costal margin in the midclavicular line. This anatomical landmark provides a safe alternative site for initial trocar or Veress needle insertion in laparoscopic surgery, particularly valuable in bariatric patients who may have previous abdominal surgery, large umbilical hernias, or hepatomegaly. The location is chosen because it is typically free of adhesions and provides direct access to the peritoneal cavity while avoiding major vascular structures. In bariatric surgery, Palmer's point access is especially useful given the higher incidence of previous abdominal procedures in this patient population.
Usage
Usage note: Named after Raoul Palmer; useful in patients with abdominal wall abnormalities.
