Objective To review the latest comparative research of minimally invasive transforaminal lumbar interbody fusion (TLIF) and traditional open approach. Methods The domestic and foreign literature concerning the comparative research of minimally invasive TLIF and traditional open TLIF was reviewed, then intraoperative indicators, length of hospitalization, effectiveness, complication, fusion rate, and the effect on paraspinal muscles were analyzed respectively. Results Minimally invasive TLIF has less blood loss and shorter length of hospitalization, but with longer operation and fluoroscopic time. Minimally invasive surgery has the same high fusion rate as open surgery, however, its effectiveness is not superior to open surgery, and complication rate is relatively higher. In the aspect of the effect on paraspinal muscles, in creatine kinase, multifidus cross-sectional area, and atrophy grading, minimally invasive surgery has no significant reduced damage on paraspinal muscles. Conclusion Minimally invasive TLIF is not significantly superior to open TLIF, and it does not reduce the paraspinal muscles injury. But prospective double-blind randomized control trials are still needed for further study.

Results Compared with the traditional treatment modalities, both of fast-track surgery and laparoscopy used for the treatment of colorectal cancer have better clinical effects. Conclusions Fast-track surgery and laparoscopic techniques used for the treatment of colorectal cancer are feasible, but the combination of the two should be confirmed by further randomized controlled trials.
ObjectiveTo summarize the recent development of the magnetic compression anastomosis in surgery. MethodsThe abroad and domestic relevant literature about magnetic compression anastomosis was extensively reviewed, and comprehensive analyzed. ResultsMagnetic compression anastomosis in the reconstruction of the body lumen is a simple and effective way; laparoscopy combined with magnetic compression anastomosis has the advantages of small wound and quick recovery. Magnetic compression anastomosis has been increasingly used in cl inical practice. But its mechanism has not been fully revealed, and it is difficulty in expelling out of the magnet for the gastrointestinal and certain large-size lumen, so further research and optimization are still needed. ConclusionRelative to the traditional manual suture, magnetic anastomosis has great advantage, especially a combination of magnetic compression anastomosis and minimally invasive surgery has bright prospects for development.
ObjectiveTo evaluate the safety of a less traumatic surgical approach in minimally invasive direct coronary artery bypass (MIDCAB). MethodsWe retrospectively analyzed the clinical data of 70 patients underwent MIDCAB via left anterior small thoracotomy between May 2012 and August 2013. There were 60 male and 10 female patients with a mean age of 56.8±9.2 years (ranged 44-76 years), with single vessel disease (left anterior descending artery) in 42 patients,and double or three vessels disease in 28 patients (include left main vessel disease). ResultsThe procedure were successfully completed in all 70 patients. No operation-related death or complication occurred. The extubation time was 4-16 (9.7±5.2) hours. The ICU time was 10-24(20.8±10.8)hours. They were followed up for 1-14 months. No deaths or angina or myocardial infarction occurred. Postoperative coronary angiography in 17 patients found no restenosis. ConclusionMIDCAB via left anterior small thoracotomy can be performed safely by using the new left internal mammary artery (LIMA) harvesting system.
ObjectiveTo investigate the effectiveness of individual percutaneous cannulated screws fixation of computer-assisted design combined with three-dimensional (3D) guide plate by comparing with cast immobilization and open internal fixation for treatment of Herbert type Ib scaphoid fracture. MethodsBetween January 2010 and June 2015, 56 patients with fresh Herbert type Ib scaphoid fracture were treated with cast immobilization in 16 cases (external fixation group), with open reduction and internal fixation in 20 cases (open reduction group), and with individual percutaneous cannulated screws fixation of computer-assisted design combined 3D guide plate in 20 cases (minimal invasion group). There was no significant difference in gender, age, injury cause, side, disease duration, and classification of fractures between groups P>0.05).The time of bone union, bone nonunion rate, return-to-work time, wrist range of motion (ROM), and Mayo function score were recorded and compared. ResultsPrimary healing of incision was obtained in open reduction group and minimally invasion group, without related complications. The cases were followed up 10-24 months (mean, 16.6 months). The time of bone union and return-to-work time of minimal invasion group were significantly shorter than those of the other 2 groups (P<0.05), and the rate of bone nonunion was significantly lower than that of the other 2 groups (P<0.05). At last follow-up, the wrist ROM of minimal invasion group[(104.40±3.46)°] was significantly larger than that of external group[(94.20±2.42)°] and open reduction group[(96.40±2.66)°] (P<0.05). According to Mayo function score, the results were excellent in 6 cases, good in 5 cases, fair in 2 cases, and poor in 3 cases in external fixation group, with an excellent and good rate of 69%; the results were excellent in 9 cases, good in 7 cases, fair in 2 cases, and poor in 2 cases in open reduction group, with an excellent and good rate of 80%; the results were excellent in 16 cases, good in 3 cases, and fair in1 case in minimal invasion group, with an excellent and good rate of 95%; there was significant difference in excellent and good rate among groups (P<0.05). ConclusionIndividual percutaneous cannulated screws fixation of computer-assisted design combined with 3D guide plate has satisfactory effectiveness in the treatment of Herbert type Ib scaphoid fractures, with the advantages of mini-invasion, high accuracy, high rate of bone union, less complication, early return-to-work time.
Objective To explore the feasibility，safety and clinical applicability of combined complete thoracoscopicand laparoscopic esophagectomy for the treatment of esophageal carcinoma. Methods Clinical data of 34 patients with esophageal carcinoma who underwent combined complete thoracoscopic and laparoscopic esophagectomy in the Departmentof Thoracic Surgery of our hospital from January 2012 to June 2013 were analyzed retrospectively. There were 33 males and1 female with their age of 63 （41-76） years. Results One patient received conversion to laparotomy and 1 patient diedpostoperatively. Mean operation time was 362.1 （300-560） minutes，including 90.6 （60-220） minutes for thoracoscopicprocedure in 34 patients and 61.1 （45-85） minutes for laparoscopic procedure in 33 patients. Mean intraoperative blood loss was 206.5 （100-500） ml. Average number of dissected lymph nodes was 18.0 （13-31） for each patient with positivemetastatic rate of 44.1% （15/34）. Postoperative pathological diagnosis was squamous cell carcinoma in 33 patients and smallcell carcinoma in 1 patient. Postoperative pathological staging was stageⅠB in 1 patient，stageⅡA in 1 patient，stageⅡB in 15 patients，stageⅢA in 11 patients，stageⅢB in 3 patients and stageⅢC in 3 patients. Postoperative hospital stay was 15.2 （6-35） days. Two patients received bedside bronchoscopic sputum suction. Postoperative complications occurred in32.4% （11/34） of all patients，including pulmonary infection in 4 patients （11.8%），respiratory failure in 2 patients （5.9%），chylothorax in 1 patient （2.9%），cervical anastomotic leak in 4 patients （11.8%） and hoarseness in 2 patients （5.9%）. We followed up 33 patients for 1-16 months. Two died，Two were lost. The other 29 patients survived. Conclusion Combined complete thoracoscopic and laparoscopic esophagectomy is a minimally invasive，feasible and safe surgical procedure for the treatment of esophageal carcinoma with quick postoperative recovery，and is worthy of furtherclinical application.
ObjectiveTo analyze clinical outcomes of mitral valvuloplasty (MVP) via right anterolateral minithoracotomy. MethodsClinical data of 23 patients with valvular heart disease who underwent minimally invasive MVP via right anterolateral minithoracotomy from January 2011 to February 2013 in the Department of Cardiothoracic Surgery in our hospital were retrospectively analyzed. There were 8 males and 15 females with mean age of 41±10 years. The procedure was performed through a small (4-6 cm) incision via right anterolateral minithoracotomy. Cardiopulmonary bypass (CPB) was established via femoral artery and vein cannulation. Transthoracic clamp was used for ascending aortic clamping. Cold blood cardioplegia was delivered after aortic cross-clamping. Left atrial drainage was established through right superior pulmonary vein. MVP was performed through the atrial septal approach,and tricuspid valvuloplasty was performed for tricuspid regurgitation if necessary. ResultsAll the operations were successfully performed without in-hospital death. Operation duration was 160-290 (229±37) minutes. Aortic cross-clamping time was 40-121 (67±19) minutes. CPB duration was 60-136 (87±21) minutes. Postoperative mechanical ventilation time was 6-47 (16±11) hours. The length of intensive care unit stay was 19-60 (30±12) hours. Postoperative chest drainage was 80-780 (320±184) ml. Postoperative color Doppler echocardiography showed that left ventricular ejection fraction was 49%-65% (56.0%±4.8%). There were 5 patients with trivial mitrial valve regurgitation and 6 patients with mild tricuspid valve regurgitation. Postoperative mean length of the right thoracic incision was 3.9-6.0 (5.3±0.7) cm. The patients were followed up for 1-24 months. The result of echocardiography showed no modern to severe valve regurgitation. ConclusionMinimally invasive MVP via right anterolateral minithoracotomy is safe and feasible with satisfactory cosmetic and clinical results.
Objective To explore effectiveness of minimally invasive internal fixation with locking plates for mid-shaft clavicle fractures. Methods Between October 2022 and August 2023, 28 patients with mid-shaft clavicle fractures were treated by minimally invasive internal fixation with locking plates. There were 10 males and 18 females with a mean age of 46.2 years (range, 18-74 years). The fractures were caused by traffic accident in 16 patients, sports-related injury in 7 patients, and other injuries in 5 patients. According to Robinson classi?cation, the fractures were classified as type 2A1 in 1 case, type 2A2 in 6 cases, type 2B1 in 15 cases, and type 2B2 in 6 cases. The interval between fracture and operation ranged from 5 hours to 21 days (median, 1.0 days). The pain visual analogue scale (VAS) score was 8.1±1.6. The VAS score at 3 days after operation and the occurrence of complications after operation were recorded. During follow-up, X-ray films were re-examined to observe the healing of the fracture; the shoulder joint function was evaluated according to the Constant-Murley score at 6 months, and the length of the incision scar (total length of the distal and proximal incisions) was measured. ResultsAll operations were successfully completed without any subclavian vascular or nerve damage. All incisions healed by first intention. The VAS score was 1.2±0.7 at 3 days after operation, and there was a significant difference in VAS score between pre- and post-operation (t=8.704, P<0.001). At 1 week after operation, the patient’s shoulder was basically painless, and they resumed normal life. All patients were followed up 12-20 months (mean, 13.3 months). X-ray films showed that the bone callus began to form at 2-4 months after operation (mean, 2.7 months). There was no delayed healing or non healing of the fracture, and no loosening or fracture of the internal fixators during follow-up. At 6 months after operation, the mean total incision length was 1.5 cm (range, 1.1-1.8 cm); no patient complained of numbness or paresthesia on subclavicular region or anterior chest wall. The Constant-Murley score of shoulder joint function was 93-100 (mean, 97.6). Conclusion Minimally invasive internal fixation with locking plates is a good surgical method for treating mid-shaft clavicle fractures, with simple operation, minimal trauma, good postoperative results, and high satisfaction.
Objective To evaluate the effect of endoscopic surgery combined with intraoperative color Doppler ultrasound on removing the injected breast augmentation agents and share our experiences. Methods Sixteen female who accepted the bilateral removal of injected breast augmentation agents through endoscopic surgery combined with intraoperative color Doppler ultrasound between 2008 and 2010 were enrolled in this study. The results, techniques, and advantages of management were analyzed retrospectively. Results One incision was made in 18 breasts, 2 in 4 breasts, 3 in 10 breasts. The length of incision was 0.5 to 1 cm. The mean operative time was 128.70 min per person. The average amount of bleeding was 52.67 ml per person. Complications such as postoperative bleeding, infection, poor drainage, or breast augmentation agents remain did not happened in all cases. No case was turned into normal operation. Female who accepted this operation were all satisfied with the appearance of incisions. During 1-3 months follow up, neither clinically palpable mass nor sensory disturbance in nipple or areola of breast was observed. Color Doppler ultrasound or magnetic resonance showed 16 cases had been cleared free of breast augmentation agents. Conclusion With the advantages of beauty, safe, minimal invasion, and partial resection of lesions at the same time, endoscopic surgery combined with intraoperative color Doppler ultrasound was an effective approach in the removal of injected breast augmentation agents.
