Study summary

Bacterial ecology of pilonidal cysts Single centre retrospective exploratory study of medical data contained in the medical records of patients operated on in the centre between 01/08/2020 and 30/11/2020.

Read the detailed description

From the medical records of a series of patients treated for pilonidal cysts:

  1. Describe the bacteriological analyses performed on a series of non-abscessed pilonidal cysts before laser treatment
  2. Compare the bacterial flora of cysts operated on in the first instance and those reoperated on

This is a retrospective monocentric study of medical data contained in the medical records of patients operated on for pilonidal cysts and who received the same protocol:

  • Antibiotic prophylaxis (injection of 2g of Augmentin)
  • Treatment of the cyst by laser, under general anaesthesia, after dilatation of the pilonidal sinus, evisceration and bacteriological swabbing.
  • Post-operative monitoring and local care
