In simple words: This procedure widens the opening between the stomach and small intestine to help food pass through more easily.

Surgical repair of the pylorus, the opening between the stomach and the small intestine, to widen the passage and improve gastric emptying. This procedure involves an incision through the pyloric canal and suturing the defect in a way that expands the opening.

Example 1: A patient with gastric outlet obstruction due to pyloric stenosis undergoes a pyloroplasty to relieve the blockage., A patient with peptic ulcer disease causing narrowing of the pylorus undergoes a pyloroplasty to widen the opening., Following a gastrectomy, pyloroplasty is performed to ensure proper gastric emptying.

Documentation should include the diagnosis necessitating the pyloroplasty, operative details, pre- and post-operative condition, and any complications.
