Topical 0.1% indomethacin solution versus topical 0.1% dexamethasone solution in the prevention of inflammation after cataract surgery. The Study Group.

INTRODUCTION

Acute postoperative pain remains one of the most common problems, even after laparoscopic or endoscopic hernia repair. Avoiding predictive factors for acute pain after surgery or prescribing additional analgesia for a patient who has risk factors that cannot be removed can be one of the options to reduce acute postoperative pain. However, there is a lack of clinical studies that evaluate the predictive factors of postoperative pain after transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) surgeries.

AIM: To identify independent risk factors predicting pain after laparoscopic and endoscopic inguinal hernia repair.

MATERIAL AND

METHODS

A prospective, randomized clinical trial was carried out by randomising patients into 2 groups (TAPP and TEP). Pre-operative and peri-operative findings were recorded. Postoperative pain was evaluated 3 h after the surgery using a visual analogue scale (VAS). Groups of patients who felt mild pain (VAS 0-2) and patients who felt average or severe pain (VAS 3-10) were compared.

RESULTS

A total of 132 male patients were included in the study. Disease duration of more than 1 year, smoking, and TAPP surgery significantly increase the risk of moderate and strong pain 3 h after surgery. Conversely, shorter duration of symptoms and physical occupation decrease the risk of acute pain score greater than 3 according to the VAS.

CONCLUSIONS

The study shows that the duration since groin hernia appearance, smoking, physical occupation, and TAPP technique are possible predictive factors for acute postoperative pain after minimally invasive inguinal hernia repair. We suggest that for patients who have those predictors, some factors can be avoided or additional analgesia can be used.
