Objective To explore the advantage of transection the cervical muscles at sternal end and flip fixed in therapeutic bilateral huge thyroid surgery. Methods The transection of the cervical muscles at sternal end and flip fixed in 53 cases was observation group， 44 cases of the neck white line incision thyroid surgery completed for the control group. The completion of the surgery by the same group of physicians. The operative time， operation field of exposing effect， amount of bleeding in operation， postoperative complications， and postoperative drainage volume were compared between two groups. Results There was no statistically differences of sex， age， disease composition， and tumor size between two groups （P＞0.05）. Operative time， amount of bleeding， and postoperative drainage volume in observation group were shorter （less） than that in control group （P＜0.01）. The postoperative complication rate in observation group was lower than that in control group（P=0.04）. Surgical field exposure in observation group was better than that in control group （P＜0.01）. Conclusions The huge bilateral thyroid surgery with the sternal end approach is feasible and simple. The operation field exposure is better than the white line neck incision， complications after operation is less. It is worthy of clinical application.
腹壁巨大切口疝的修补是很困难的手术，在一些特殊的病例中，由于患者的全身情况严重恶化使得切口疝无法修补，如年老、病态性肥胖及呼吸功能严重紊乱的患者。近年来，随着生物材料在疝和腹壁外科的广泛应用，对巨大腹壁切口疝的治疗已取得了明显进展。
Objective To investigate the effect of coronary artery bypass grafting (CABG) on patients with coronary heart disease and giant left ventricular dimension but without aneurysm. Methods The clinic data of 51 consecutive patients with coronary heart disease accompanied by enlarged left ventricle dimension without aneurysm, including 50 males and 1 female, undergoing CABG between January 2004 and December 2006 in Nanjing First Hospital of Nanjing Medical University was retrospectively reviewed. The patients were at the age of 54-61 years with an age of 57.5±3.2 years. All patients received CABG, combined with aortic valve replacement in 7, mitral valve replacement in 16, mitral valvoplasty in 17 and tricuspid valvoplasty in 7. After surgery, perioperative complications and mortality were closely observed and followup for a period of 37 months was carried out. Results The number of distal anastomoses per patient was 2.0-4.0(3.8±1.1). Four patients died perioperatively (7.8%), among whom 2 died from malignant ventricular fibrillation, 1 from acute kidney failure and 1 from stroke caused by severe low cardiac output syndrome. All other patients were discharged from hospital with good recovery. After operation, 5 patients had atrial fibrillation and 11 had ventricular fibrillation, but all of those patients survived after proper treatment. The followup period for 47 patients was 37-49 months (43±11months), with a followup rate of 100%. No death occurred during the follow-up. Ultrasound cardiography in the followup period showed that there was a decreased left ventricular enddiastolic dimension (59±2 mm vs. 68±5 mm; t=7.320, Plt;0.05) and an improved left ventricular ejection fraction (45%±17% vs. 34%±15%; t=4.770, Plt;0.05) compared with those before operation with statistical significance. Conclusion CABG is an effective surgical procedure in the treatment of coronary heart disease with giant left ventricular dimension but without aneurysm.
Objective To evaluate the left ventricular remodeling after valve replacement for valvular heart disease with giant left ventricle. Methods The clinical material of 92 patients with valvular heart disease and giant left ventricle after valve replacement was retrospectively reviewed. The results of ultrosonic cardial gram（UCG） and the changes of cardiac function before and after operation were compared. Results There was no operative death. The value of left ventricular end-diastolic dimension （LVEDD）, left ventricular end-systolic dimension （LVESD）, left atrial dimension （LAD）, left ventricular ejection fraction （LVEF）, left ventricular fractional shortening （LVFS）, stroke volume （SV） and cardiothoracic ratio in 2 weeks and 2 months after operation were more decreased than those before operation（P〈0. 05）. The value of LVEDD and LAD in 2 months after operation were much more decreased than those in 2 weeks after operation （P〈0. 05）. The cardiac function in early stage after operation was more decreased than that before operation,but the cases of cardiac functional class Ⅱ （38 cases, 41.3% ） in 2 months after operation was significantly more than those before operation （5 cases, 5.4 % ）. Conclusions The early effect of left ventricular remodeling is significant for valvular heart disease with giant left ventricle after valve replacement. The diameter of left ventricle and left atrial are significantly decreased after operation. The protection for cardiac function should be carefully taken in order to prevent the occurrence of complication after operation.
Objective To review the progress in the treatment and research of massive rotator cuff tears. Methods Recent l iteratures about the treatment and research of massive rotator cuff tears were reviewed. Results Treatment options of massive rotator cuff tears include nonoperative treatment, debridement, direct repair, tendon transfer, and repair with various substitutes, but the outcome is unpredictable. Recently, many experimental studies on the treatment of massive rotator cuff tears, such as gene therapy, cell therapy, and tissue engineering techniques, can provide cl inicians with new treatment strategies. Conclusion The treatment of massive rotator cuff tears pose a distinct cl inical challenge for the orthopaedist, depending on the overall presentation. The effect of traditional operation method to repair massive rotator cuff tears is limited. The treatment and research of massive rotator cuff tears still need to be studied.
