A Pyloroplasty is an additional surgery that is sometimes performed in conjunction with G-tube placement or a Nissen fundoplication. In some cases, it may also be done as a stand-alone procedure.
The pylorus is the valve between the stomach and the small intestine. In some children, the pylorus does not open easily, spasms, or has thickened. This can block stomach contents from flowing into the intestine. Children may vomit, reflux, or have delayed gastric emptying. In some cases, there may be little to no movement of stomach contents into the intestine, which is called gastroparesis.
Surgeons may widen the pylorus surgically, called a Pyloroplasty, in order to help the stomach empty more readily. While this procedure is usually performed with an open incision in the abdomen, it can also be performed laproscopically. Typically, children are placed under general anesthesia. When the surgery is performed as a stand-alone procedure, pain is usual moderate after the procedure, and children rarely need more than 1-2 days in the hospital. If it is performed in conjunction with other surgical procedures, pain may be more significant, and the hospital stay may be longer.
