ARTICLE HIGHLIGHTS
Research background

Bone marrow injection by endoscopic ultrasound (EUS)-guided intraportal fine needle injection (FNI) offers an accurate targetability, and this study proved that the use of EUS-guided FNI for intraportal delivery of bone marrow stem cells was feasible and safe and appeared effective in patients with decompensated liver cirrhosis (DLC).

Research motivation

We conducted this study to investigate the feasibility and safety of fresh autologous bone marrow injection into the portal vein under EUS guidance in patients with DLC.

Research objectives

To investigate the feasibility and safety of fresh autologous bone marrow injection into the portal vein under EUS guidance in patients with DLC.

Research methods

Five patients with DLC were enrolled in this study after they provided written informed consent. EUS-guided intraportal bone marrow injection with a 22G FNA needle was performed using a transgastric, transhepatic approach. Several parameters were assessed before and after the procedure for a follow-up period of 12 mo.

Research results

Four males and one female with a mean age of 51 years old participated in this study. All patients had hepatitis B virus-related DLC. EUS-guided intraportal bone marrow injection was performed in all patients successfully without any complications such as hemorrhage. The clinical outcomes of the patients revealed improvements in clinical symptoms, serum albumin, ascites, and Child-Pugh scores throughout the 12-mo follow-up.

Research conclusions

The use of EUS-guided FNI for intraportal delivery of bone marrow was feasible and safe and appeared effective in patients with DLC. This treatment may thus be a safe, effective, non-radioactive, and minimally invasive treatment for DLC.

Research perspectives

Future multicenter and larger controlled studies with longer follow-up periods are required to determine the real potential of our novel technique for the treatment of DLC.
