Brief summary
This study aimed to evaluate whether vagus nerve-guided robotic-assisted splenectomy and azygoportal disconnection is effective and safe, and to determine whether a reduction in the incidence of postoperative complications of the digestive system improves postoperative quality of life compared with conventional robotic-assisted splenectomy and azygoportal disconnection.
Detailed description
After successful screening the cases of cirrhosis of liver irrespective of the etiology who have non tumor portal vein thrombosis will be enrolled. The baseline parameter will be recorded and the patient will be randomized into either interventional (vagus nerve-guided robotic-assisted splenectomy and azygoportal disconnection) or control (conventional robotic-assisted splenectomy and azygoportal disconnection) group. From postoperative day 3, all patients will receive 2.5 mg oral Apixaban tablets (Bristol-Myers Squibb, Cruiserath, USA) twice daily for 6 months, low-molecular-weight heparin (CS Bio, Hebei, China) subcutaneously (4.100 IU/day) for 5 days, and 25 mg of oral dipyridamole (Henan Furen, Henan, China) thrice daily for 3 months. At months 3 after operation, electron gastroscopy examination for delayed gastric emptying will be done for all patients. Postoperative complications of the digestive system (including diarrhea, epigastric fullness, bloating, nausea, and vomiting), liver and renal function, and body weight will be recorded at the seventh day and months 3 after operation. Then 3 months monitoring will be done in the both groups as per the primary or secondary outcome.
Interventions
PROCEDUREvagus nerve-guided group
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.
