Dr. Sunil Amin, a gastroenterologist at the University of Miami Health System, explains how a minimally invasive procedure called G-POEM is helping patients with a debilitating condition where the stomach does not empty properly. Samantha Cowan is one of those patients.

Ten years ago, the simple act of eating became difficult for Samantha Cowan.

“When I would eat, I would immediately feel like the food was just trying to come right back up,” says Samantha. “Bloating and just constant stomach pain.”

Samantha was diagnosed with gastroparesis, a condition where the stomach does not empty properly, says UHealth gastroenterologist Dr. Sunil Amin.

“As a result, you experience symptoms such as nausea, vomiting, bloating, and something called early satiety, which means you take a few bites of food and you get full very quickly,” says Sunil Amin, M.D.

When other treatments failed, Samantha went to see Dr. Amin who is performing a new procedure called G-POEM. UHealth is one of the few centers in the country offering this highly specialized procedure.

“Doctor, what is G-POEM and what does that stand for?” asks anchor Pam Giganti.

“G-POEM stands for gastric peroral endoscopic myotomy,” Dr. Amin says. “It’s an endoscopic procedure that’s minimally invasive, that we perform through the mouth, and we cut the muscle called the pylorus, which is at the end of the stomach.”

The muscle opens and closes allowing food to enter the small intestine.

“By cutting it, we allow it to relax and thus allow food to enter the intestine much more easily,” says Dr. Amin.

Samantha had the G-POEM procedure in April.

“I stayed overnight in the hospital and was able to go home the next day,” Samantha says.

Now she can enjoy meals with her family and friends without worrying.

“The nausea is gone. The pain is gone. It’s really been life changing for me,” says Samantha.
