295 Open Minimally Invasive vs Video-Assisted Minimally Invasive Parathyroidectomy for Solitary Adenomas: A Systematic Review and Meta-Analysis

Abstract Aim To conduct a meta-analysis comparing two minimally invasive techniques; Video Assisted Minimally Invasive Parathyroidectomy (VAMIP) and Open (OMIP). Method A systematic review were carried out in line with the Preferred Reporting Items for Systematic Reviews Meta-analyses (PRISMA) Guidelines. Databases from MEDLINE, EMBASE, CINAHL identified Randomised Controlled Trials (RCTs), cohort observational studies that compared VAMIP OMIP. The primary outcome measures assessed VAS score 24 hours after surgery, conversion of operation to open, failure rates analgesic consumption. Secondary outcomes operative time, hospital stay length, scar length. These studies' data extracted statistically analysed. Results literature search yielded 104 which 4 included, enrolling 903 patients this analysis. significant difference was found regarding open parathyroidectomy between groups, OMIP group demonstrating fewer conversions (MD= 3.52, CI= (2.04–6.08), P< 0.00001). No differences groups when post-op 24hrs -1.75, (-9.8–6.3) P= 0.67), consumption analgesia (OR= 0.49, 0.07–3.54, P=0.48) or 1.81, 0.58–5.72, 0.31). had quicker times similar complication lengths MIVAP. Conclusions seen require less need convert shorter More are required evaluate superior technique parathyroidectomy.
