How is the mcburney incision made for an open procedure?
Step-by-step method1. Identify the McBurney Point: The McBurney point is located midway between the anterior superior iliac spine (ASIS) and the umbilicus.
2. Incision: Make a 2 to 5 cm vertical or transverse incision over the McBurney point, through the skin and subcutaneous tissue.
3. Expose Rectus Sheath: Extend the incision through the rectus sheath to expose the underlying rectus muscle.
4. Retract Muscles: Incise the tendinous insertion of the external oblique muscle and gently retract both the rectus muscle medially and the internal oblique and transversus abdominis muscles laterally.
5. Open Peritoneum: After confirming the location, carefully enter the peritoneal cavity through a small incision in the peritoneum.
Additional techniques:
- If necessary, extend the incision superiorly or laterally to provide access to the appendix, cecum, or surrounding structures.
- Depending on the surgeon's preference, electrocautery, diathermy, or surgical blades can be used to make the necessary incisions.
- The McBurney incision can be enlarged into a paramedian or transverse incision if needed during the procedure.
