PDS vs. ProlenePermanent Versus Slowly Dissolving Stitches for Non-Mesh (Shouldice) Groin Hernia Repair

The goal of this clinical trial is to learn whether slowly dissolving stitches work as well as permanent stitches for repairing a groin (inguinal) hernia in adults using the Shouldice technique, a hernia repair that does not use mesh. Researchers think dissolving stitches may cause less long-term groin discomfort without making the hernia more likely to come back. The main questions it aims to answer are:

Is the chance of the hernia coming back within 1 year different with dissolving stitches (PDS) compared with permanent stitches (Prolene)?

Do the two types of stitches differ in complications, groin pain, quality of life, or the feeling of something foreign in the groin?

Is a larger future study of this question possible? This includes whether enough people join, whether the study plan is followed, and whether participants complete follow-up.

Researchers will compare slowly dissolving polydioxanone (PDS) stitches with permanent polypropylene (Prolene) stitches to see if the hernia comes back at similar rates and if patients have less long-term discomfort.

Participants will:

Have their planned open Shouldice hernia repair. The type of stitch will be chosen at random, like flipping a coin, during surgery.

Not be told which stitch they received until 1 year after surgery, or sooner if the hernia comes back or another operation is needed.

Complete questionnaires about pain, activity, and quality of life before surgery and about 30 days, 6 months, and 1 year after surgery.

See their surgeon for routine visits about 30 days and 1 year after surgery.

Receive one research phone call about 6 months after surgery.

Answer whether they feel something foreign in their groin and which type of stitch they think they received.
