Vagus nerve–guided laparoscopic spleen removal with azygoportal disconnection

Vagus Nerve-guided Laparoscopic Splenectomy and Azygoportal Disconnection

Not applicable Interventional Northern Jiangsu People's Hospital · NCT07462091

This procedure tests whether a vagus nerve–guided laparoscopic spleen removal plus azygoportal disconnection helps people with cirrhosis, portal hypertension, and hypersplenism who have had gastroesophageal variceal bleeding.

What this trial studies

Adults with cirrhosis and secondary hypersplenism who have had gastroesophageal variceal bleeding are enrolled after screening and baseline measurements. All participants undergo a vagus nerve–guided laparoscopic splenectomy with azygoportal disconnection and then receive a standardized postoperative anticoagulation regimen (apixaban for 6 months, short-course low‑molecular‑weight heparin, and dipyridamole for 3 months). Digestive symptoms, liver and renal function, weight, and complications are recorded at postoperative day 7 and month 3, and gastroscopy for delayed gastric emptying is performed at 3 months. Primary and secondary outcomes are monitored over the 3‑month postoperative period.

Who should consider this trial

Good fit: Ideal candidates are patients with cirrhosis (not Child‑Pugh C) who have splenomegaly with secondary hypersplenism and bleeding from portal hypertension, with no portal vein thrombosis and who can take the required postoperative medications.

Not a fit: Patients with delayed gastric emptying or diarrhea at baseline, hepatocellular carcinoma or other malignancy, active hypercoagulable states, portal vein thrombosis, Child‑Pugh C cirrhosis, pregnancy, uncontrolled hypertension, HIV, or current use of anticoagulant/antiplatelet drugs are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, the procedure could reduce variceal bleeding and correct hypersplenism while minimizing postoperative digestive complications and improving quality of life.

How similar studies have performed: Laparoscopic splenectomy and azygoportal disconnection have been used in cirrhotic portal hypertension with some positive reports, but the vagus nerve–guided variant has relatively limited published outcome data.
