Objective:To provide a preliminary comparison between minimally invasive non-endoscopic thyroidectomy with a low anterior cervical incision (L-MINT) vs. minimally invasive video-assisted thyroidectomy (MIVAT).Subjects and Methods:Fuzhou General Hospital general surgery in September2012-September2013there were437cases of invasive thyroidectomy were selected, according to the inclusion criteria after exclusion of191patients were enrolled, including free line of minimally invasive endoscopic thyroidectomy89cases, line102cases of endoscopic assisted thyroidectomy. Parameters included:demographic and baseline information, incision length, operation time and bleeding, postoperative pain, drainage, cosmetic satisfaction, complications and hospital stay.Results:Compared to no significant difference2groups of patients with general information and tumor size(P>0.05, table1); L-MINT group compared with MIVAT group incision length, blood loss, postoperative drainage was no significant difference (P>0.05), the same two groups no significant difference in postoperative pain scores on beauty and (P>0.05, table3). L-MINT group after group and MIVAT incision occurred were seroma one case and two cases, the two groups had no secondary bleeding required reoperation. L-MINT set of four cases of transient hoarseness after MIVAT group three cases these symptoms are alleviated by symptomatic treatment, the two groups revealed no permanent hoarseness. Postoperative transient hypocalcemia L-MINT group three cases, MIVAT group1patients, no permanent hypocalcemia. Recurrent laryngeal nerve injury and postoperative complications incidence of hypocalcemia two groups had no difference (Table3). Surgical time and cost, MIVAT group67.5±19.0min, L-MINT group43.4±14.1min. L-MINT group compared with MIVAT group was significantly shorter than the more operative time. Although no difference in the two groups of hospital stay, but the cost is higher in the MIVAT group (P<0.05,Table3). Conclusion:L-MINT is as safe as MIVAT, but requires shorter surgical time than MIVAT. Considering the requirement for less equipments, we recommend L-MINT as an alternative to MIVAT, particularly in less developed parts of the world.
