Objective To explore an effective micro-traumatechnic with small incision for hallux valgus. Methods From August 2002 to June 2004, 136 cases (263 feet) with hallux valgus were treated with micro-trauma technic with small incision and postoperative external elastic fixation. Of all the cases, 7 were males and 129 werefemales. Their ages ranged from 19 to 84 years. According to Coughlin classification, there were 24 gentle cases, 63 medium cases, and 49 severe cases. All the feet were with some degree of pain and flatfoot. Symptom, sign and theresults of X-ray were evaluated. Results Wound healed at stage Ⅰ.All cases were followed up for 8 to 26 months, 19 months on average. Hallux valgus of the 263 feet were completely healed, feet pain disappeared, and no nonunion or osteonecrosis was observed. Xray examination indicated that 105 feet’s hallux valgus angle was less than 12°, inter metatarsal angle less than 9°, and remedy subluxation of the tibial sesamoid less than 50%. Evaluation on the result indicated that there were 84 cases of excellent result, 48 cases of good result, 3 cases of fair result, and 1 case of poor result. The rate of excellent and good was 97%. Conclusion With less injury, less pain, complete restoration, and fewer possibility of relapse, microtrauma technic with small incision is effective in treating hallux valgus.
ObjectiveTo compare early outcomes of the minimally invasive mitral valve surgery (MIMVS) through right anterolateral mini-thoracotomy (ALMT) with conventional mitral valve surgery (MVS), and evaluate feasibility and safety of MIMVS. MethodsFrom January 2011 to December 2013, 120 patients undergoing elective MVS in Nanjing First Hospital were prospectively enrolled in this study. There were 72 male and 48 female patients with their age of 22-71 (42.4±11.0) years. Using a random number table, all the patients were randomly divided into a portaccess MIMVS group (MIMVS group, n=60) and a conventional MVS group (conventional group, n=60). MIMVS group patients received port-access cardiopulmonary bypass (CPB) establishment via femoral artery, femoral vein and right internal jugular vein cannulation through right ALMT 5-6 cm in length. Special MIMVS operative instruments were used for mitral valve repair or replacement. Conventional group patients received mitral valve repair or replacement under conventional CPB through median sternotomy. Perioperative clinical data, morbidity and mortality were compared between the 2 groups. ResultsThere was no death in-hospital or shortly after discharge in this study. CPB time (98.0±26.0 minutes vs. 63.0±21.0 minutes) and aortic cross-clamping time (68.0±9.0 minutes vs.37.0±6.0 minutes) of MIMVS group were significantly longer than those of conventional group (P<0.05). Postoperative mechanical ventilation time (6.0±3.9 hours vs. 11.2±5.6 hours), length of ICU stay (18.5±3.0 hours vs. 28.6±9.5 hours) and postoperative hospital stay (8.0±2.0 days vs. 13.5±2.5 days) of MIMVS group were significantly shorter than those of conventional group (P<0.05). Chest drainage volume within postoperative 12 hours (110.0±30.0 ml vs. 385.0±95.0 ml) and the percentage of patients receiving blood transfusion (25.0% vs. 58.3%) of MIMVS group were significantly lower than those of conventional group (P<0.05). Patients were followed up for 1-24 months, and the follow-up rate was 94.2%. There was no statistical difference in postoperative morbidity or mortality between the 2 groups (P>0.05). ConclusionMIMVS through right ALMT is a safe and feasible procedure for surgical treatment of mitral valve diseases. MIMVS can achieve similar clinical outcomes as conventional MVS, but can significantly shorten postoperative ICU stay and hospital stay, reduce blood transfusion, and is a good alternative to conventional MVS.
Objection To compare the effects of three mainstream surgical methods on the ocular surface and investigate the optimal corneal myopia correction surgery. Methods We selected 118 patients (236 eyes) undergoing small incision lamellar extraction (SMILE) (40 patients, 80 eyes), femtosecond-laser in situ keratomileusis (FS-LASIK) (36 patients, 72 eyes) or sub-Bowman keratomileusis (SBK) (42 patients, 84 eyes) surgery for corneal myopia correction from March 2015 to January 2016. Before surgery, one week and one month after surgery, tear film rupture time, tear river height and eye red index were measured using ocular surface analyzer. The Schimer Ⅰ test was used to detect tear secretion. Corneal sensory gauge was used to measure corneal sensation. Analysis of variance was used to analyze the measurements of the three surgical methods at various time points. Results The tear film rupture time of the three groups decreased after one week (P<0.05), but the time in the SMILE group [(9.643±4.751) seconds] was longer than those in the other two groups [FS-LASIK (8.172±4.300) seconds, SBK (7.612±3.691) seconds,P<0.05]. The time in the SMILE group at one month after surgery was not different from that before surgery (P>0.05). At one month after surgery, the rupture times of the other two groups were still shortened (P<0.05). The tear river heights in the three groups were decreased at one week and one month after surgery (P<0.05), except FS-LASIK group (P>0.05). In the SBK group, at one week after surgery, the decrease of the height was the most obvious (P<0.05). There was no difference in eye red index among the three groups at the time of observation (P>0.05). Corneal sensation decreased in the three groups at one week and one month after surgery. In the SBK group, that was the most obvious decline (P<0.05). In the three groups, the tear secretion did not change at each observation time point (P>0.05). Conclusion In the three surgical methods, SMILE has the minimal impact on the ocular surface, followed by FS-LASIK, and SBK has the greatest impact.
