Question

an incision into the upper sphincter of the stomach is a surgical procedure known as:
a dysphagia
b pylorotomy
c pylorectomy
d sigmoidectomy

Explanation:

Dysphagia is difficulty swallowing, not a surgical procedure. Pylorotomy is an incision in the pyloric sphincter (lower part of stomach). Pylorectomy is removal of the pylorus. Sigmoidectomy is removal of the sigmoid colon. None of the given options are correct for an incision into the upper sphincter of the stomach. But if we assume a mis - statement and it was meant to be lower sphincter (pylorus), pylorotomy is an incision procedure.

Answer:

B. pylorotomy
