Pyloric stenosis is rare infant condition that blocks food from entering the small intestine. Pylorus is a muscular valve between the stomach and small intestine. It keeps food in the stomach until it is ready to go to small intestine. But in pyloric stenosis, the pylorus thickens and gets enlarged causing blockage of food from entering the small intestine.
Symptoms of Pyloric Stenosis
Symptoms usually appear within three to five weeks after birth and may include the following:
-
Forceful projectile vomiting
-
Persistent hunger
-
Dehydration
-
Less urination
-
Weight loss
-
Less active or unusually irritable
Diagnosis of Pyloric Stenosis
Diagnosis often starts with a physical examination of the abdomen that may reveal an olive-shaped lump or an enlarged pyloric muscle and peristaltic waves. In addition to this, following tests are performed to confirm the diagnosis:
-
Ultrasound
-
X-rays of digestive system
-
Blood tests to check for dehydration or electrolyte imbalance or both
Laparoscopic surgery for Pyloric Stenosis
Pyloromyotomy is performed for pyloric stenosis and is often done using minimally invasive surgery (Laparoscopy).
The procedure is performed under general anaesthesia with surgeon making 3-4 tiny incisions in the abdomen. One of the incisions is used to insert a port (nozzle) that fills the carbon dioxide gas into the abdomen to inflate it. Now laparoscope is inserted through another incision. A laparoscope is a telescope lookalike with a light and camera on the end. It allows the surgeon to clearly view inside of the abdomen on the monitor outside. Now using surgical instruments, cuts are made in the pylorus to loosen the muscle and enhance the opening of the stomach. After the completion of procedure, incisions are closed with sutures or staples, or covered with glue-like bandage.
Advantages of Laparoscopic Pyloromyotomy
-
Less pain
-
Shorter operative time
-
Better cosmetic result
-
Shorter hospital stay
-
Lower requirement for intravenous narcotics
-
Faster recovery
-
Negligible risks and complications
-
Less chances of wound infection
-
High success rate
