Port site hernia: What are the risk factors?

Hernias are a common problem affecting millions of Americans. Most people are familiar with the term hernia, though they do not understand what they are, why they happen, where, and what treatments are available for this common physical ailment. With June designated as National Hernia Awareness Month, it is the perfect time to educate on the causes of and effective treatments for hernia patients.


Hernia in its simplest term is a hole where there should not be. Essentially it is a defect, or an opening through the body or muscle wall which presents as a lump or bulge in the low to mid-stomach region. Though important to note, hernias can occur in other areas. Patients can have a herniated disc or a hiatal hernia, which is an opening through the diaphragm. Patients can also have hernia's in their internal organs. Though most common are inguinal hernias (groin hernias) and body wall hernias (abdominal hernias).



Various factors have been implicated in the development of port site hernia. Tayeb S. Kareem and Renas A. Farman made a retrospective study of patients who underwent different elective laparoscopic procedures in Rizgary Teaching Hospital in Erbil in a period from March 2013 to September 2014, to identify the risk factors of port site hernia.


They found that out of 300 patients only 8 (2.7%) patients developed port site hernia. The time of the hernia occurrence ranged from 3 weeks to six months postoperatively. Half of the hernias were found in cases of age group (60-80) years. Six (75%) of the cases were female patients. All 8 hernias developed after laparoscopic cholecystectomy. Six hernias (75%) developed after open port entrance technique. All hernias occurred when the fascia in 10 mm port was not closed. Seven hernias (87.5%) occurred in patients with BMI ranged (25-34).


In conclusion, age of the patients, technique of entrance, site and size of the port with unclosed fascial layer are important factors for developing port site hernia.
