ABSTRACT
Objective:To investigate the effect of modified Miccoli surgery in the treatment of patients with benign thyroid disease and its intervention on the postoperative aesthetic degree of scar score and the expression of pain factors.Methods:The clinical data of 114 patients with benign thyroid diseases in Hankou Hospital from February 2018 to February 2020 were collected, 57 cases with traditional open thyroid surgery were enrolled in the open group, and 57 cases with modified Miccoli surgery were enrolled in the modified group. The surgery related indicators, postoperative recovery indicators, complications and preoperative, postoperative 1, 3 d serum pain factors substance P (SP), β-endorphin (β-EP), dynorphin ( DYN), immune function indexes CD 3+, CD 4+, CD 8+, parathyroid function related indexes parathyrotropic hormone(PTH), blood calcium, 3 months and 6 months after surgery of observer scar evaluation scale (OSAS), Vancouver scar scale (VSS) scores were compared between the two groups. Results:The length of incision, recovery time of neck movement, and hospital stay and the intraoperative blood loss were lower than those in the open group: (2.2 ± 0.4) cm vs. (6.5 ± 0.7) cm, (19.6 ± 4.8) h vs. (28.2 ± 7.8) h, (4.8 ± 1.4) d vs. (7.1 ± 1.8) d, (21.9 ± 5.1) ml vs. (39.5 ± 7.0) ml, the differences were statistically significant ( P<0.05). The levels of serum SP, β-EP and DYN in the modified group were lower than those in the open group at 1 and 3 d after operation: 1 d after surgery:(87.40 ± 12.25) ng/L vs. (114.96 ± 15.79) ng/L, (149.34 ± 21.49) ng/L vs.(192.15 ± 26.43) ng/L, (1.14 ± 0.21) mg/L vs. (1.59 ± 0.30) mg/L; 3 d after surgery: (80.18 ± 10.79) ng/L vs.(96.24 ± 12.36) ng/L, (137.46 ± 18.57) ng/L vs. (168.24 ± 21.50) ng/L, (0.94 ± 0.16) mg/L vs. (1.27 ± 0.25) mg/L, the differences were statistically significant ( P<0.05). The levels of CD 3+ and CD 4+ in the modified group were higher than those in the open group at 1 and 3 d after the operation, and the CD8+ level was lower than that of the open group: 1 d after surgery: 0.597 ± 0.053 vs. 0.542 ± 0.049, 0.382 ± 0.041 vs. 0.362 ± 0.036, 0.308 ± 0.048 vs. 0.332 ± 0.060; 3 d after surgery: 0.615 ± 0.060 vs. 0.580 ± 0.055, 0.408 ± 0.051 vs. 0.385 ± 0.046, 0.290 ± 0.038 vs. 0.317 ± 0.045, and the differences were statistically significant ( P<0.05). The levels of serum PTH and blood calcium in the modified group were higher than those in the open group at 1 and 3 d after operation: 1 d after surgery: (29.12 ± 6.58) ng/L vs. (20.67 ± 5.14) ng/L, (1.86 ± 0.22) mmol/L vs. (1.59 ± 0.10) mmol/L; 3 d after surgery: (36.39 ± 7.65) ng/L vs. (24.08 ± 5.97) ng/L, (2.03 ± 0.18) mmol/L vs. (1.72 ± 0.14) mmol/L, the differences were statistically significant ( P<0.05). The OSAS and VSS scores of the modified group were lower than those of the open group at 3 and 6 months after surgery: 3 months after surgery: (15.9 ± 3.3) scores vs. (24.7 ± 6.9) scores, (4.4 ± 1.5) scores vs. (8.1 ± 3.2) scores; 6 months after surgery: (10.3 ± 2.7) scores vs. (17.1 ± 5.4) scores, (3.3 ± 1.2) scores vs. (6.9 ± 2.4) scores, the differences were statistically significant ( P<0.05). The incidence of postoperative complications in the modified group was lower than that in the open group: 3.51%(2/57) vs. 15.79%(9/57), the difference was statistically significant ( P<0.05). Conclusions:The application of modified Miccoli surgery in patients with benign thyroid diseases can reduce the length of the incision, reduce the impact on postoperative pain stress, immune function, and parathyroid function, speed up the process of postoperative recovery, improve the appearance of postoperative aesthetic degree of scar, and reduce the risk of complications.
ABSTRACT
Objective To compare the therapeutic effects between cervical and extra-cervical surgical approaches for endoscopic thyroidectomy . Methods From October 2012 to December 2013, forty-four thyroid goiter patients were divided into two groups randomly .Group A underwent modified Miccoli endoscopic thyroidectomy ( n =20 ) and group B underwent endoscopic thyroidectomy via breast areola approach ( n=24 ) .The operative time , intraoperative blood loss , pain in 24 hours postoperatively , drainage volume , postoperative hospital stay , hospital cost , complication and cosmetic results between the two groups were compared . Results Compared with group B, group A had shorter operative time [(77.9 ±28.3) min vs.(97.9 ±30.0) min, t=-2.259, P=0.029], less intraoperative blood loss [(15.9 ±8.7) ml vs.(29.5 ±16.1) ml, t=-3.384, P=0.002], less pain in 24 hours postoperatively ( no pain, endurable pain , intolerable pain in group A and B were 15, 5, 0 and 7, 15, 2 cases respectively , Z=-3.066, P=0.002), less postoperative drainage volume [(31.7 ±10.3) ml vs.(57.0 ±14.6) ml, t=-6.511, P=0.000], but poorer cosmetic results (very dissatisfied, not satisfied, satisfied, comparatively satisfied, and very satisfied in group A and B were 1, 4, 5, 6, 4 and 0, 1, 4, 5, 14 cases respectively, Z=-2.723, P=0.006).There was no significant difference in postoperative hospital stay and hospital cost between the two groups (P>0.05).One case suffered transient hoarseness in group A and one case had trembling hand due to low calcium level in group B and both of them recovered 1 month after symptomatic treatment .No permanent recurrent laryngeal nerve injury , parathyroid injury or other complications occurred in both groups . Conclusions Cervical approach is minimally invasive and leads to good cosmetic results while extra-cervical approach causes bigger trauma but leads to better cosmetic results.Patients with high cosmetic reguest may choose endoscopic thyroidectomy via breast areola approach .
