Efficacy and Safety of Transforaminal Percutaneous Endoscopic Discectomy in Treatment of Patients Suffering From Discogenic Low Back Pain in Kenya.

BACKGROUND

Low back pain (LBP) is a globally prevalent condition, often attributed to lumbar disc herniation (LDH). Transforaminal percutaneous endoscopic discectomy (TPED) is a minimally invasive surgical approach for LDH, offering distinct advantages. This study aimed to assess the progression of pain in patients who underwent TPED in Kenya, with a focus on the impact of pre-existing factors.

METHODS

This retrospective study included 610 patients from the Mediheal Group of Hospitals who underwent TPED between January 2018 and December 2022. Data were collected from medical records, direct patient interactions, and telephone interviews. Statistical analyses, including repeated measures analysis of variance, correlation coefficients, and tests, were used to examine pain progression and factors influencing outcomes.

RESULTS

Among the 610 included patients, all reported LBP and 87.9% reported leg pain. TPED resulted in significant pain reduction ( < 0.001) for both LBP and leg pain, with sustained improvement over 1 year. Factors such as age, body mass index, and duration of pain correlated with pain outcomes. No significant impact of comorbidities on pre- or postoperative pain was observed. Its retrospective design and the absence of a control group limit the strength of causal inferences.

CONCLUSIONS

TPED is an effective treatment for LBP and leg pain in Kenyan patients with LDH. Pain improvement was sustained over 1 year after performing TPED, and pre-existing factors influenced outcomes. This study provides valuable insights into TPED outcomes, contributing to the understanding of LDH management in diverse populations.
