Trocar site hernia or port site hernia (PSH) is a type of incisional hernia occurring at the trocar sites after laparoscopic surgeries. This is a rare but a potentially dangerous complication, as it can lead to considerable morbidity requiring surgical intervention. Various factors have been implicated for its development and various methods are also suggested for its prevention. We present here five cases of port site herniae.Keywords Laparoscopy .

Case ReportsCase 1 A 43-year-old fit female presented with a swelling in the left lower abdomen for about 2 years. Pain developed about 10 days ago. On examination, there was a globular, mildly tender, and irreducible swelling of about 8 cm diameter in the left iliac fossa in the subcutaneous plane, with an 8-mm irregular trocar site scar on the skin (Fig. 1). The pain aggravated on coughing with no obvious cough impulse. Old records showed that she had undergone a diagnostic laparoscopy for infertility, and a 10-mm optical port was used at the umbilicus and a 5-mm port at the left iliac fossa, and only functional cysts of the ovaries were found, for which no treatment was suggested. There was no mention about the closure of trocar sites. A clinical diagnosis of irreducible laparoscopic 5 mm port site hernia was made, which was confirmed by abdominal ultrasound. She was operated through a transverse incision made over the swelling, and the hernia sac could easily be identified, after splitting the external oblique muscle fibers. The sac was opened and it contained viable omentum. The neck of the sac was about 7 mm in diameter, which was widened more to push back the omentum into the abdominal cavity. The abdominal cavity was explored by inserting a finger through the hernia defect and no adhesions were found. The sac was excised, the defect closed with 1-0 polypropropylene, and a polypropylene mesh was placed over the internal oblique muscle and fixed with 1-0 polypropylene sutures. The external oblique muscle was approximated with 2-0 polyglactin sutures over the mesh. The skin and subcutaneous tissues were approximated with staples. The patient had uneventful recovery and remains asymptomatic without recurrence about 5 years after surgery.Case 2 A 53-year-old female presented with a large swelling in the lower abdomen (Fig. 2), which developed after laparoscopic cholecystectomy done 3 years ago by us. She had noticed this swelling about a year after surgery, and abdominal pain was of recent onset. Though reducible, while standing, the swelling was very prominent and caused back pain. She was diagnosed to have a 10-mm port site hernia, which was confirmed by ultrasonography. Incidentally, she was a cured case of non-Hodgkin's lymphoma, non-cirrhotic portal fibrosis with portal hypertension, and anemia due to hypersplenism. Our records showed that the umbilical port site was closed with a 1-0 polypropylene. Open surgery was performed for this hernia and a large defect of about 15 cm was identified which was closed with 1-0 po...
