Collis

Collis is a medical term referring to a surgical procedure that lengthens the esophagus. This procedure is often performed in conjunction with a Nissen fundoplication to treat conditions such as gastroesophageal reflux disease (GERD) and hiatal hernia.

Procedure

The Collis procedure involves creating a new, longer esophagus by cutting the upper part of the stomach and pulling it upwards. This is then stitched to the existing esophagus, effectively lengthening it. The procedure is named after the surgeon who first described it, N. R. Barrett.

Indications

The Collis procedure is typically indicated for patients with a short esophagus, often as a result of chronic GERD or a hiatal hernia. These conditions can cause the lower esophageal sphincter to be positioned in the chest rather than the abdomen, leading to reflux. By lengthening the esophagus, the sphincter can be repositioned in the abdomen, reducing reflux.

Risks and Complications

As with any surgical procedure, the Collis procedure carries risks. These can include infection, bleeding, and damage to surrounding organs. There is also a risk of dysphagia (difficulty swallowing) following the procedure.
