Dr. Banis studies advanced surgical techniques and methods to improve the treatment of conditions affecting the lip, throat, and esophagus, particularly after traumatic injuries or cancer surgeries. He investigates how microsurgery can repair damaged areas and how innovations like free tissue transfer and autografts can rebuild functionality after significant surgical resections. His research also looks at the implications of blood flow reduction on blood clot formation in surgical contexts, aiming to optimize patient outcomes and safety.
Key findings
In a study of 13 lip replantation surgeries, all procedures were successful, with one patient experiencing partial loss due to surgical error.
When blood flow was reduced to about half, the number of downstream clots decreased from approximately 260 to 44, indicating a significant impact on clot formation.
Among 41 patients with advanced head and neck cancer, 54% controlled the original cancer site, and 88% managed neck area control, with 18 patients free of cancer after an average follow-up of 18 months.
The use of free bowel autografts after surgical removal of throat and esophagus parts achieved a 97% success rate, demonstrating a reliable reconstruction method.
Angiography successfully diagnosed visceral artery aneurysms in patients with gastrointestinal bleeding, aiding in effective emergency treatment.
Frequently asked questions
Does Dr. Banis study lip injuries?
Yes, he has researched the surgical reattachment of lips after traumatic injuries and has achieved successful outcomes.
What treatments has Dr. Banis researched for throat cancer?
He has studied the effectiveness of surgical methods combined with free tissue transfer in treating advanced head and neck cancer.
Is Dr. Banis's work relevant to patients with esophageal surgery?
Absolutely, his research includes reconstructive techniques following esophageal surgeries, showing high success rates with minimal complications.
What is the impact of blood flow on blood clots during surgery?
His study found that reducing blood flow greatly decreases the number of clots that form downstream, which can improve surgical outcomes.
How does Dr. Banis help patients with gastrointestinal bleeding?
He has explored diagnosis and management techniques for patients with bleeding related to visceral artery aneurysms, aiding in more effective treatment planning.

Plastic and reconstructive surgery
Walton RL, Beahm EK, Brown RE, Upton J, Reinke K +8 more
Plain English This study looked at how effective lip replantation is after traumatic injuries, reviewing 13 cases from 12 hospitals. All 13 surgeries were successful, although one patient experienced partial loss due to a mistake during the procedure. Patients were generally satisfied with their results, showing good muscle movement and sensation in the repaired lip, which is important for both appearance and function.
Who this helps: This research benefits patients who suffer from lip amputations, as well as the doctors performing these complex surgeries.

Microsurgery
Andresen DM, O'Shaughnessy M, Acland RD, Anderson GL, Schuscke D +2 more
Plain English This study looked at how reducing blood flow affects blood clots (thrombus) and tiny clots that travel downstream (emboli) in an animal model. Researchers found that when blood flow was decreased to about half of what it normally is, the number of tiny clots that appeared downstream dropped significantly from about 260 to about 44. This reduction in flow slowed down the growth of the clot at the injury site but didn't change its size.
Who this helps: This information benefits surgeons and patients undergoing procedures like reconstructive surgery, as it may lead to better outcomes.
Irradiation and free tissue transfer in head and neck cancer.

Head & neck
Jose B, Banis J, Flynn M, Lindberg R, Spanos WJ +2 more
Plain English This study looked at how surgery, radiation treatment, and reconstruction using free tissue transfer affect patients with advanced head and neck cancer. Researchers treated 41 patients, finding that 54% had control of the original cancer site, and 88% had control in the neck area. 18 patients were living without any signs of cancer after an average follow-up of 18 months, demonstrating that this approach is effective with minimal complications.
Who this helps: This benefits patients with advanced head and neck cancer by providing effective treatment options.
Reconstruction with free bowel autografts after pharyngoesophageal or laryngopharyngoesophageal resection.

American journal of surgery
Flynn MB, Banis J, Acland R
Plain English This study looked at a method for rebuilding parts of the throat and esophagus after surgical removal due to disease. The researchers found that using a free bowel autograft, where a piece of healthy bowel is taken from the patient and used for reconstruction, had a success rate of 97%. This is important because it shows a highly reliable option for patients who undergo this type of surgery, reducing the chances of severe complications.
Who this helps: This benefits patients recovering from throat and esophagus surgery.
Angiography as an aid in extra-enteric gastrointestinal bleeding due to visceral artery aneurysm.
1978
Annals of surgery
Keehan MF, Kistner RL, Banis J
Plain English This study examined three patients with rare blood vessel bulges called visceral artery aneurysms that were causing bleeding in the digestive system. The researchers found that they could accurately diagnose these aneurysms using a technique called angiography before surgery, which helped plan the right treatment steps. In two cases where the patients had low blood volume, they successfully applied a targeted emergency angiography approach to manage the situation effectively.
Who this helps: This benefits patients with gastrointestinal bleeding due to visceral artery aneurysms and the doctors treating them.
