We discuss our results, comparing this procedure (from a technical point of view) with the muscle-preserving interlaminar decompression (MILD) and the unilateral approach for bilateral decompression (ULBD). Clinical and outcome data of 62 consecutive patients were reviewed, using the Visual Analogue Scale for both low back pain (LBP) and legs pain and the Oswestry Disability Index (ODI) for the degree of disability. Mean age was 68.88 ± 9.54 years and mean follow-up (FU) was 16.38 ± 11.12 months. A statistically significant improvement of LBP, legs pain and ODI was globally observed. At latest FU, patients with multilevel lumbar spinal stenosis significantly improved all scores and patients with spondylolisthesis significantly decreased their disability. No major complications occurred. Two cerebrospinal fluid (CSF) collections were treated conservatively. No wound infection occurred. No progression of spondylolisthesis was observed. No reoperation was needed. Although efficacious in patients with lumbar spinal stenosis, MILD and ULBD can have both some limitations. MILD has been found to decrease lumbar function in multilevel decompression (increasing sagittal translation and lumbar lordosis probably due to the removal of half of the spinous processes) and ULBD shows some disadvantages due to the difficulty of manipulating instruments through a small portal and the inadequate decompression due to a minimal exposure. The minimal invasive bilateral interlaminar decompression (in this technique, the access is bilateral but the supraspinous and interspinous ligaments and the spinous processes are preserved) allows wide access (bilateral exposure) with minimal invasiveness and very low morbidity in patients with lumbar spinal stenosis at one or more levels.展开更多

METHODS PubMed, Web of Science, EMBASE, and the Cochrane Library were searched comprehensively for studies comparing MILDH with conventional living donor hepatectomy (CLDH). Intraoperative and postoperative outcomes (operative time, estimated blood loss, postoperative liver function, length of hospital stay, analgesia use, complications, and survival rate) were analyzed in donors and recipients. Articles were included if they: (1) compared the outcomes of MILDH and CLDH; and (2) reported at least some of the above outcomes. RESULTS Of 937 articles identified, 13, containing 1592 patients, met our inclusion criteria and were included in the meta-analysis. For donors, operative time [weighted mean difference (WMD) = 20.68, 95% CI: -6.25-47.60, p = 0.13] and blood loss (WMD = -32.61, 95% CI: -80.44-5.21, p = 0.18) were comparable in the two groups. In contrast, analgesia use (WMD = -7.79, 95% CI: -14.06-1.87, p = 0.01), postoperative complications [odds ratio (OR) = 0.62, 95% CI: 0.44-0.89, p = 0.009], and length of hospital stay (WMD): -1.25, 95% CI: -2.35-0.14, p = 0.03) significantly favored MILDH. No differences were observed in recipient outcomes, including postoperative complications (OR = 0.93, 95% CI: 0.66-1.31, p = 0.68) and survival rate (hr = 0.96, 95% CI: 0.27-3.47, p = 0.95). Funnel plot and statistical methods showed a low probability of publication bias. CONCLUSION MILDH is safe, effective, and feasible for living donor liver resection with fewer donor postoperative complications, reduced length of hospital stay and analgesia requirement than CLDH.展开更多
