About this study
This study aimed to evaluate the effectiveness and safety of vagus nerve-guided laparoscopic splenectomy and azygoportal disconnection, and to assess its impact on postoperative digestive complications and quality of life.
Interventions
- Procedure: Vagus nerve-guided laparoscopic splenectomy and azygoportal disconnection — The vagus nerve-guided procedure was performed in the following order: (1) find the left crural diaphragm; (2) via the surface of the left crural diaphragm, blunt dissect the left lateral surface of the distal esophagus using Bipolar Forceps, and find posterior vagal trunk; (3) along posterior vagal trunk towards left lateral esoph-agogastric junction, find and protect gastric and celiac branches; (4) enter the lesser omental sac from the right crural diaphragm using Bipolar Forceps; (5) transect the left gastric artery and vein together using a linear vascular stapler; (6) blunt dissect the anterior surface of the distal esophagus using Bipolar Forceps, and find anterior vagal trunk; (7) along anterior vagal trunk towards right lateral esoph-agogastric junction, find and protect gastric and hepatic branches; and (8) blunt dissect the right lateral surface of the distal esophagus. The hepatogastric ligament was conserved.
Primary outcomes
- Incidence of Postoperative Diarrhea (3 months)
- Incidence of Delayed Gastric Emptying (3 months)
