Summary
Accurate anatomical identification of splanchnic nerves and ganglia is crucial for effective surgical splanchnicectomy in managing pancreatic cancer pain. This study details the precise location, number, and dimensions of these structures in cadavers to improve surgical outcomes.
Area of Science:
- Anatomy
- Surgical Anatomy
- Pain Management
Context:
- Surgical splanchnicectomy is a palliative approach for intractable neoplastic pain, particularly from pancreatic cancer.
- Accurate identification of splanchnic nerves and ganglia during laparotomy is essential for successful pain relief.
- Variations in the anatomical course and morphology of these structures can pose surgical challenges.
Purpose:
- To precisely delineate the anatomical location, number, shape, and length of the splanchnic nerves and semilunar ganglia.
- To provide detailed anatomical data to aid surgeons in identifying these structures during palliative splanchnicectomy.
- To establish a baseline for understanding anatomical variations relevant to surgical planning.
Summary:
- This study analyzed 15 cadavers to map the right and left splanchnic nerves and ganglia.
- Detailed measurements and positional data were recorded regarding their entry through the diaphragm, relation to surrounding structures (inferior vena cava, aorta, coeliac trunk, superior mesenteric artery), length, thickness, and ganglionic variations.
- The right splanchnic nerve averaged 41 mm and had 2-6 ganglia, while the left averaged 24 mm with 2-4 ganglia.
Impact:
- Improved anatomical knowledge can enhance surgical precision during splanchnicectomy for pancreatic cancer pain.
- Reduced surgical complications and improved long-term pain management efficacy.
- Provides valuable anatomical references for surgeons and anatomists involved in visceral pain interventions.
