Dr. Musunuru studies surgical procedures and their impact on various health conditions. He investigates how to improve surgeries for ailments related to the trachea, the stomach, and the liver, among others. For instance, he researches ways to strengthen surgical connections in trachea operations to enhance recovery chances. He also examines treatments for conditions like gastroesophageal reflux disease (GERD), where previous surgeries have failed, and how electric stimulation can assist patients with gastroparesis, a condition affecting stomach emptying. His work also looks into the effectiveness of surgical options for patients with liver cancer.
Key findings
Tracheas with cartilage reinforcing sutures required a breaking force of 297 newtons, compared to 173 newtons for those without, improving surgical strength.
In a study of 38 patients who underwent follow-up surgery for failed GERD treatment, 79% had prior issues related to hiatal hernia, though most reported satisfactory outcomes despite longer recovery times.
After one year of gastric electrical stimulation treatment, all diabetic patients showed significant symptom relief, while only 4 out of 15 total patients did not improve.
A study revealed that using Ligasure during thyroid surgery reduced the surgery time by 40 minutes without increasing complications.
Patients undergoing surgical treatment for liver neuroendocrine tumors had an 83% survival rate after three years, in contrast to 31% for those receiving other medical therapies.

Perioperative outcomes of surgical procedures for symptomatic fundoplication failure: a retrospective case-control study.
2012
Surgical endoscopy
Musunuru S, Gould JC
Plain English This study looked at patients who had surgery to fix problems from a previous surgery for gastroesophageal reflux disease (GERD) that didn't work, known as fundoplication. Out of 38 patients who needed this follow-up surgery, it was found that most had a previous surgery fail due to a common issue called hiatal hernia, with 79% experiencing this. Although the repeat surgeries took longer, required longer hospital stays, and had more complications, most patients were still satisfied with their results, with many reporting minimal or manageable symptoms afterward.
Who this helps: Patients dealing with ongoing GERD symptoms after initial surgery.

Otolaryngology--head and neck surgery : official journal of American Academy of Otolaryngology-Head and Neck Surgery
Schilt PN, Musunuru S, Kokoska M, McRae B, O'Neill D +1 more
Plain English This study examined whether adding special cartilage sutures outside a surgical connection of the trachea makes it stronger. Researchers tested 12 tracheas from cadavers and found that those with the cartilage sutures needed a force of 297 newtons to break, while those without only required 173 newtons. This improvement means there's a better chance of preventing early ruptures after trachea surgery, which is important for patient recovery.
Who this helps: This helps patients undergoing trachea surgery.
Preoperative predictors of significant symptomatic response after 1 year of gastric electrical stimulation for gastroparesis.
2010
World journal of surgery
Musunuru S, Beverstein G, Gould J
Plain English This study looked at how well gastric electrical stimulation (GES) helps patients with difficult-to-treat gastroparesis, a condition where the stomach can't empty properly. After one year, only 4 out of 15 patients showed no improvement with GES, while all diabetic patients reported significant relief from symptoms. This is important because it helps doctors identify which patients are likely to benefit the most from this expensive treatment, ensuring that those who need it most receive it.
Who this helps: This helps patients with gastroparesis, especially those with diabetes.
The use of the Ligasure for hemostasis during thyroid lobectomy.
2008
American journal of surgery
Musunuru S, Schaefer S, Chen H
Plain English This study looked at the use of a device called Ligasure during thyroid surgery to see if it would make the surgery faster. The researchers found that using Ligasure shortened the surgery time by 40 minutes compared to traditional methods, without increasing complications. This matters because shorter surgery times can lead to quicker recovery for patients.
Who this helps: This helps patients undergoing thyroid surgery.
Effective surgical residents strongly influence medical students to pursue surgical careers.
2007
Journal of the American College of Surgeons
Musunuru S, Lewis B, Rikkers LF, Chen H
Plain English This study looked at how surgical residents—doctors in training—affect medical students' decisions to become surgeons. Researchers found that medical students who worked with highly rated surgical residents were more likely to choose a career in surgery, with 12% of those who learned from the best residents going into surgery compared to only 4.9% from those with less effective residents. This is important because it shows that having strong role models and teachers in surgical training can significantly encourage more medical students to enter the surgical field.
Who this helps: Medical students and future surgical trainees.
Computed tomography in the diagnosis of acute appendicitis: definitive or detrimental?
2007
Journal of gastrointestinal surgery : official journal of the Society for Surgery of the Alimentary Tract
Musunuru S, Chen H, Rikkers LF, Weber SM
Plain English This study looked at how using CT scans affected the diagnosis and treatment of appendicitis in adults at a hospital over three years. It found that 62% of patients who had surgery for appendicitis received a CT scan before their operation, and those patients experienced longer wait times (8.2 hours) compared to those who didn't have a scan (5.1 hours). This delay was linked to a higher rate of appendiceal perforation, with 17% of the CT group experiencing perforations compared to 8% in the group without a scan. Because of these findings, it is important to use CT scans carefully in suspected cases of appendicitis to avoid worse outcomes.
Who this helps: This information aids doctors in making better decisions about when to use CT scans for appendicitis.

Plain English This study looked at different treatments for patients with cancer in the liver caused by neuroendocrine tumors. It found that patients who underwent surgical treatment had a significantly better survival rate, with 83% still alive after three years compared to just 31% for those who received medical therapy or embolization. This matters because it highlights that surgery can greatly improve the chances of survival for these patients.
Who this helps: This helps patients with liver-only neuroendocrine tumors.
A mouse model of carcinoid syndrome and heart disease.
2005
The Journal of surgical research
Musunuru S, Carpenter JE, Sippel RS, Kunnimalaiyaan M, Chen H
Plain English This study looked at how carcinoid syndrome affects the heart using a mouse model. The researchers found that 65% of the mice developed liver tumors, which led to significantly higher serotonin levels in their blood (over 10 times more than those without tumors) and thicker heart valves, similar to what happens in humans with carcinoid heart disease. Understanding this connection is important as it could lead to better treatments for patients with this condition.
Who this helps: This helps patients with carcinoid syndrome and their doctors.
