The pelvic area — A central hypogastric area for abdominal palpation for women with abdominal pain: A narrative review

The pelvic area is a central hypogastric area which is conformed with the pelvic inlet to reduce overlapping of the non-pelvic area and is more sensitive and specific in diagnosing female abdominal emergencies than the traditional four quadrants and nine regions methods for abdominal palpation. The purpose of this narrative review is to assess the principle and mechanism of formation of the pelvic area for abdominal palpation for women with abdominal pain. By classifying the abdominal area as inside or outside the pelvic area, abdominal pain can be located inside or outside the pelvic cavity, thereby distinguishing pelvic diseases from non-pelvic diseases. When the examiner divides the patient's pelvic area along the pelvic ring using his/her hand on the patient's contralateral abdomen, there can be a reduced pain zone under the hand and alleviate pain in the non-diseased area. It allows patients with poor perception of tenderness or abdominal pain with guarding to easily recognize pelvic or non-pelvic pain. Partitioning the pelvic area which conforms with pelvic cavity inlet can reduce confusing pelvic and non-pelvic diseases when using traditional four quadrants or nine regions method. The division of the pelvic area on the patient's contralateral side can induce a reduced pain zone under the hand and alleviate pain in the non-diseased area, which can help the patient distinguish between pelvic and non-pelvic pain. Pain is a subjective feeling to the patient, and correct patient perception of pain are the basis for a correct diagnosis.
