In brief, it can but it is rare if the surgeon concerned is skilled and careful.
The enlargement (hypertrophy) of the pyloric ring muscle in babies does sometimes reoccur after the operation, but there don't seem to have been any studies to find out how often this happens over a significant number of cases. Typically, there are a few recurrences and one death reported in surveys of say about 100 operations in one centre, but other reports admit to very few complications and less than 1:100 deaths.
The surgery (pyloromyotomy) stops the blockage of the stomach outlet by slitting the muscle ring down to but not including the inner lining (omentum) of the gastric passage. Too long or deep a slit opens the gastric passage and must be immediately recognised and repaired to prevent a catastrophic infection setting in. But if the slit in the muscle band is not long enough or if the cut edges are not spread widely enough to let the omentum bulge into the cut, the cut muscle will close, reconnect and can then continue to enlarge as a result of the biochemical process that caused the original swelling.
So IPS can reoccur - but how often depends on the skill and thoroughness of the surgeon concerned, and will vary from one to another.
In adults the pyloric muscle or valve can be closed by scarring (from ulceration) or cancer. Sometimes pyloric stenosis in infancy is not severe enough to warrant surgery and for whatever reason some of these children grow up still having problems with their pyloric function. Problems with the pyloric sphincter in adults can be managed by medication, lifestyle changes, and/or surgery.
Frequent vomiting may be an indication of pyloric stenosis and of other gastic complaints. In PS the vomiting will be violent (arch-like), not bile stained, and develop to become so persistent that the baby loses weight and condition. When this happens it is high time to see a doctor and if necessary insist on tests for PS.
The bottom of the stomach is the pyloric area, with the pyloric sphincter separating the stomach from the duodenum (first portion of the small intestine). The top of the stomach is the cardiac area with the cardiac sphincter. The pre-pyloric area is the area just above the phyloric sphincter where they do biopsies to test for an H-Pylori infection. The pyloric area consists of two parts the pyloric canal and the pyloric antrum.
erosion in the pre-pyloric region
Pyloric sphincter controls the movement of food from stomach to duodenum. With parasympathetic or vagal stimulation it opens up or relaxes and with sympathetic stimulation it contracts or closes.
Male infants with a family history of pyloric stenosis are more at risk of having the condition, which tends to occur less often in females, blacks, and Asians.
