About this study
Official title: Vagus Nerve-guided Versus Conventional Robotic-assisted Splenectomy and Azygoportal Disconnection
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.
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
vagus nerve-guided groupProcedure or surgery
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.

Questions about this trial
What is this clinical trial studying?
A study testing vagus nerve-guided group in people with Cirrhosis and Hypertension, run by Northern Jiangsu People's Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Apr 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diarrhea (time frame: 3 month). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05300516, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2026.
