What does JOHN SEMIAN research?

Dr. Semian studies the outcomes of surgical procedures, particularly hernia repairs, and how factors like obesity and surgical techniques affect patient recovery. In one study, he examined the risks of acute kidney injury—a sudden decline in kidney function—associated with a specific surgical method called transversus abdominis release during large ventral hernia repairs. His research also explores the impacts of obesity on surgical outcomes, focusing on patients with a body mass index (BMI) over 40 who undergo abdominal wall hernia surgeries and their risk of infections or complications.

Key findings

  • Patients undergoing the transversus abdominis release technique during large ventral hernia repairs had an 11% rate of acute kidney injury compared to 6% in those who did not have this technique.
  • Obese patients (BMI over 40) had significantly longer surgery times and an 8.55% infection rate after hernia repair with mesh, compared to 1.1% in patients with lower BMI.
  • The return rate of hernias post-surgery was not affected by the patient's obesity status, indicating the need for further research into how obesity influences surgery decisions.

Frequently asked questions

Does Dr. Semian study kidney issues related to surgery?
Yes, he specifically investigates the risk of acute kidney injury associated with surgical techniques used in hernia repairs.
What treatments has Dr. Semian researched?
He focuses on surgical techniques for hernia repairs, particularly in patients with obesity and those undergoing transversus abdominis release.
Is Dr. Semian's work relevant to patients with obesity?
Absolutely, his research is specifically relevant to patients with obesity who are at a higher risk for complications during and after hernia surgeries.

Acute Kidney Injury After Large Ventral Hernia Repair Requiring Transversus Abdominis Release.

2022

The American surgeon

Schaeffer HD, Sharp NE, Jaap K, Semian J, Alaparthi M +3 more

Plain English
This study looked at whether a surgical technique called transversus abdominis release (TAR) used during large ventral hernia repairs leads to a higher risk of kidney problems after surgery. The researchers found that patients who had TAR were nearly twice as likely to develop acute kidney injury (AKI) after the surgery, with an AKI rate of 11% compared to 6% in patients who did not have TAR. This matters because identifying higher risks for kidney injury can help doctors take better care of their patients during and after surgery. Who this helps: This helps patients undergoing large ventral hernia repairs.

Outcomes of Open Retro-Rectus Hernia Repair With Mesh in Obesity Class III.

2020

The American surgeon

Martinez M, Dove J, Blansfield J, Widom K, Semian J +2 more

Plain English
This study looked at patients with obesity (BMI over 40) who had surgery to fix abdominal wall hernias with a mesh. Researchers found that these patients had longer surgery times and a higher chance of getting infections after surgery (8.55% compared to 1.1% in patients with lower BMI). However, having a higher BMI did not affect the rate of hernia returning after the surgery, which means more research is needed to understand how obesity impacts surgery outcomes and if it should affect surgery decisions. Who this helps: This benefits patients with obesity who are considering hernia surgery.
