Summary

Non-dissolving plain gut sutures caused persistent irritation years after pars plana vitrectomy (PPV). Surgical removal was necessary to alleviate the patient's foreign body sensation and discomfort.

Area of Science:

  • Ophthalmology
  • Surgical Innovation
  • Biomaterials Science

Background:

  • Pars plana vitrectomy (PPV) is a common surgical procedure for various retinal conditions.
  • Sclerotomies created during PPV may require suturing for wound closure and complication prevention.
  • Plain gut sutures are sometimes used for their perceived lower inflammatory profile.

Observation:

  • A 79-year-old male experienced chronic foreign body sensation and irritation in his left eye.
  • Examination revealed non-dissolved plain gut sutures in the subconjunctiva, three years post-PPV.
  • Histopathology confirmed the sutures as dense collagenous material consistent with gut.

Findings:

  • Plain gut sutures, intended for absorption, failed to dissolve three years after PPV.
  • The persistent sutures caused significant patient discomfort and foreign body sensation.
  • Suture fragments were successfully removed, providing symptomatic relief.

Implications:

  • This case highlights the potential for delayed or absent absorption of plain gut sutures.
  • It underscores the importance of long-term monitoring for suture-related complications after PPV.
  • Consideration of alternative suture materials or techniques may be warranted to ensure predictable absorption and patient comfort.
