Introduction
In most cases, the surgical site for appendicitis is located in the right lower abdomen, specifically at the junction of the outer and middle one-third of the line connecting the umbilicus and the right anterior superior iliac spine (McBurney's point). If pain in the right lower abdomen worsens, prompt medical attention is recommended. Anatomically, the appendix is situated at the junction of the ileum and cecum in the right lower abdomen, and its surface projection corresponds to McBurney's point. In most cases of appendicitis, this area exhibits significant tenderness.
Under normal circumstances, the surgical site for appendicitis is located in the lower right abdomen, specifically at the junction of the outer and middle one-third of the line connecting the navel and the right anterior superior iliac spine (McBurney's point). If pain in the lower right abdomen worsens, prompt medical attention is recommended. Detailed analysis is as follows:
Anatomically, the appendix is situated at the junction of the ileum and cecum in the lower right abdomen. Its surface projection corresponds to McBurney's point. In most cases of appendicitis, significant tenderness occurs at this location, and surgery requires an incision in this area to quickly locate and remove the appendix, thereby minimizing surgical trauma.
In rare cases, due to individual anatomical variations, the appendix may be abnormally positioned—such as in the upper right abdomen or within the pelvic cavity. In such instances, the surgical site will be adjusted according to the actual position of the appendix determined by preoperative examinations (e.g., ultrasound, CT), ensuring precise identification of the diseased appendix and preventing intraoperative injury to surrounding organs.
When experiencing pain in the lower right abdomen, avoid pressing on the area or taking painkillers independently, as this may mask the condition. Once appendicitis is diagnosed, follow medical advice regarding the timing of surgery. After surgery, pay attention to wound care to prevent infection, and undergo regular age-appropriate health checkups to comprehensively monitor your health status.
