RESUMEN

Purpose@#The objective of this study was to compare the perioperative outcomes between single-incision laparoscopic appendectomy (SILA) and 3-port conventional laparoscopic appendectomy (CLA) in enhanced recovery after surgery (ERAS) protocol. @*Methods@#Of 101 laparoscopic appendectomy with ERAS protocol cases for appendicitis from March 2019 to April 2020, 54 patients underwent SILA with multimodal analgesic approach (group 1) while 47 patients received CLA with multimodal analgesic approach (group 2). SILA and CLA were compared with the single institution’s ERAS protocol. To adjust for baseline differences and selection bias, operative outcomes and complications were compared after propensity score matching (PSM). @*Results@#After 1:1 PSM, well-matched 35 patients in each group were evaluated. Postoperative hospital stays for patients in group 1 (1.2 ± 0.8 vs. 1.6 ± 0.8 days, P = 0.037) were significantly lesser than those for patients in group 2. However, opioid consumption (2.0 mg vs. 1.4 mg, P=0.1) and the postoperative scores of visual analogue scale for pain at 6 hours (2.4±1.9 vs. 2.8 ± 1.4, P = 0.260) and 12 hours (2.4 ± 2.0 vs. 2.9 ± 1.5, P = 0.257) did not show significant difference between the 2 groups. @*Conclusion@#SILA resulted in shortening the length of hospitalization without increase in complications or readmission rates compared to CLA with ERAS protocol.

RESUMEN

BACKGROUND AND OBJECTIVES: MicroRNA 145 is known to be responsible for cellular proliferation, and its enhanced expression reportedly inhibits the retardation of vascular smooth muscle cell growth specifically. In this study, we developed a microRNA 145 nanoparticle immobilized, hyaluronic acid (HA)-coated stent. MATERIALS AND METHODS: For the gene therapy, we used disulfide cross-linked low molecular polyethylenimine as the carrier. The microRNA 145 was labeled with YOYO-1 and the fluorescent microscopy images were obtained. The release of microRNA 145 from the stent was measured with an ultra violet spectrophotometer. The downstream targeting of the c-Myc protein and green fluorescent protein was determined by Western blotting. Finally, we deployed microRNA 145/ssPEI nanoparticles immobilized on HA-coated stents in the balloon-injured external iliac artery in a rabbit restenosis model. RESULTS: Cellular viability of the nanoparticle-immobilized surface tested using A10 vascular smooth muscle cells showed that MSN exhibited negligible cytotoxicity. In addition, microRNA 145 and downstream signaling proteins were identified by western blots with smooth muscle cell (SMC) lysates from the transfected A10 cell, as the molecular mechanism for decreased SMC proliferation that results in the inhibition of in-stent restenosis. MicroRNA 145 released from the stent suppressed the growth of the smooth muscle at the peri-stent implantation area, resulting in the prevention of restenosis at the post-implantation. We investigated the qualitative analyses of in-stent restenosis in the rabbit model using micro-computed tomography imaging and histological staining. CONCLUSION: MicroRNA 145-eluting stent mitigated in-stent restenosis efficiently with no side effects and can be considered a successful substitute to the current drug-eluting stent.
