ObjectiveTo investigate the technique and efficacy of left atrial appendage (LAA) occlusion during off-pump coronary artery bypass grafting (OPCABG) in elderly patients with coronary artery disease (CAD) and atrial fibrillation (AF).MethodsFrom 2013 to 2018, 84 elderly patients with CAD and AF with reduced left ventricular ejection fraction (LVEF< 50%) underwent OPCABG in our department. There were 54 males and 30 females at age of 70-82 years. They were divided into a left atrial appendage (LAA) occlusion group (n=56) and a non-LAA occlusion group (n=28). Postoperative antithrombotic therapy: the LAA occlusion group was given warfarin + aspirin + clopidogrel “triple antithrombotic therapy” for 3 months after operation, then was changed to aspirin + clopidogrel “dual antiplatelet” for long-term antithrombotic; the non-LAA occlusion group was given warfarin + aspirin + clopidogrel “triple antithrombotic” for long-term antithrombotic after operation. The clinical effectiveness of the two groups was compared.ResultsAll patients underwent the surgery successfully. There were 56 patients in the LAA occlusion group, including 44 patients of LAA exclusion and 12 patients of LAA clip. The time of LAA occlusion was 3 to 8 minutes. There was no injury of graft vessels and anastomotic stoma. Early postoperative death occurred in 2 patients (2.4%). There was no statistical difference between the two groups in postoperative hospital stay (P=0.115). Postoperative LVEF of the two groups significantly improved compared with that before operation (P<0.05). There was no stroke or bleeding in important organs during hospitalization. During follow-up of 1 year, no cerebral infarction occurred in both groups, but the incidence of bleeding related complications in the LAA occlusion group was significantly lower than that in the non-LAA occlusion group (3.6% vs. 18.5%, P=0.036).ConclusionFor elderly patients with CAD and AF with reduced LVEF, LAA occlusion during OPCABG can effectively reduce the risk of stroke and bleeding related complications, and without increasing the risk of surgery.
A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.
ObjectiveTo analyze the feasibility and effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound.MethodsThe clinical data of 30 patients with the fifth metacarpal neck fractures who were treated with elastic intramedullary nails fixation under the guidance of high frequency ultrasound and met the selection criteria between May 2013 and September 2017 were retrospectively analysed. There were 24 males and 6 females, the age ranged from 18 to 58 years, with an average of 31.4 years. The head-shaft angle of the fifth metacarpal was (55.6±11.3)°. The time from injury to operation was 12 hours to 8 days, with an average of 2.4 days. The operation time, number of intraoperative fluoroscopy, fracture reduction, complications, and fracture healing time were recorded. The head-shaft angle of the fifth metacarpal on the affected side after fracture healing were measured and compared with the healthy side. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint of both sides were measured, and the function was evaluated by using the total active movement (TAM) evaluation standard of the Hand Surgery Association of Chinese Medical Association.ResultsThe operation time was 22-40 minutes, with an average of 32.4 minutes; the intraoperative fluoroscopy was performed once; ultrasound images and X-ray fluoroscopy showed that the fracture was well reduced and no adjustment was required. The incisions healed well after operation, without tendon adhesion or local numbness. All 30 patients were followed up 8-16 months, with an average of 11.7 months. The fracture healing time was 4-8 weeks, with an average of 5.6 weeks. The head-shaft angle of the fifth metacarpal was (13.2±1.4)°, which was significantly improved when compared with preoperative value (t=−20.02, P=0.00); and there was no significant difference (t=1.94, P=0.06) when compared with the healthy side [(12.6±1.0)°]. At last follow-up, the active range of motion of the fifth metacarpophalangeal joint on the affected side was (89.4±2.4)°, showing no significant difference (t=−1.58, P=0.13) when compared with the healthy side [(90.3±2.0)°]. According to the TAM evaluation standard of the Hand Surgery Association of Chinese Medical Association, all patients were considered to be excellent.ConclusionThe effectiveness of elastic intramedullary nail fixation for the fifth metacarpal neck fracture under the guidance of high frequency ultrasound is definite. It can dynamically observe the fracture reduction from different angles, reduce ionizing radiation and postoperative complications.

ObjectiveTo compare the clinical efficacy of endoscopic minimally invasive surgery and median sternotomy thoracotomy in the treatment of atrial myxoma by meta-analysis.MethodsWe searched CBM, CNKI, Wanfang Data, VIP, PubMed, the Cochrane Library and EMbase to collect relevant researches on atrial myxoma and endoscopic minimally invasive surgery. The retrieval time was from the establishment of the database to September 2020. Two reviewers independently screened the literature, extracted data and evaluated the bias risk of included studies by the Newcastle-Ottawa scale (NOS). Then, the meta-analysis was performed by Stata 16.0.ResultsTen articles were included in the study, all of which were case-control studies. The quality of literature was grade B in 5 articles and grade A in 5 articles. The sample size of surgery was 938 patients, including 480 patients in the endoscopic minimally invasive group, 458 patients in the median thoracotomy group, and 595 patients in follow-up. A total of 18 outcome indexes were included in the meta-analysis. The combined results of 9 outcome indicators were statistically significant: cardiopulmonary bypass time (SMD=0.32, 95%CI 0.00 to 0.63, P=0.048); ventilator assisted ventilation time (SMD=−0.35, 95%CI −0.56 to −0.15, P=0.001), ICU stay time (SMD=–0.42, 95%CI −0.62 to −0.21, P<0.001); postoperative hospitalization time (SMD=−0.91, 95%CI −1.22 to −0.60, P<0.001); postoperative drainage volume (SMD=−2.48, 95%CI −5.24 to 0.28, P<0.001); postoperative new onset atrial fibrillation (OR=0.29, 95%CI 0.12 to 0.67, P= 0.005); postoperative pneumonia (OR=0.09, 95%CI 0.02 to 0.36, P=0.001); postoperative blood transfusion (OR=0.22, 95%CI 0.11 to 0.45, P<0.001); incision satisfaction (OR=83.15, 95%CI 1.24 to 5563.29, P=0.039).ConclusionAvailable evidence suggests that median thoracotomy requires shorter cardiopulmonary bypass time than endoscopic minimally invasive surgery; during the 5-year follow-up after surgery and discharge, ICU stay time, postoperative hospital stay, postoperative drainage, new atrial fibrillation after surgery, postoperative pneumonia, postoperative blood transfusion, satisfactory incision, endoscopic minimally invasive surgery showed better results than median sternotomy thoracotomy.
ObjectiveTo assess the feasibility of the treatment of unresectable late pancreatic cancer with laparoscopic choledochojejunostomy and gastric bypass. MethodsFrom June 2000 to December 2003, laparoscopic choledochojejunostomy and gastric bypass were successfully performed in 15 patients with unresectable late pancreatic cancer. Endoscopic nosobiliary drainage (ENBD) was performed before the operation. ResultsAll procedures were completed laparoscopically. Jaundice and hepatic function of the patients were obviously improved after the bypass. Oral nutrition was recovered after operation. The mean operative time was (100±26) min (range 70-200 min); the mean operative blood loss was (60±15) ml (range 30-120 ml); the bowel function recovery was on the 3rd-5th postoperative day; the average hospital stay was (8.1±0.7) days (range 6-13 days). Incision infection ocurred in one patient. No operative complications occurred in other patients. ConclusionTreatment of unresectable late carcinoma of the pancreas with laparoscopic choledochojejunostomy and gastric bypass aided by ENBD is a minimally invasive technique with less postoperative pain，shorter hospital stay, lower procedurerelated morbidity,and better oral nutrition. The life quality of patients with late pancreatic cancer can be obviously improved.
Objective To observe the relationship between the suturing patterns to close the scleral incision and postoperative intraocular pressure (IOP) in 23G minimally invasive vitrectomy. Methods Eighty eyes of 80 patients with vitreoretinal diseases, who were treated with primary 23G minimally invasive vitrectomy, were enrolled in this prospective clinical study. Patients with poor closed scleral incision which need suturing were excluded from this study. The corrected visual acuity ranged from hand movement to 0.2. The IOP ranged from 7.9 to 19.8 mm Hg (1 mm Hg=0.133 kPa), with the mean of (13.9plusmn;1.8) mm Hg. The eyes were randomly divided into three groups: group A (20 eyes), suturing all three scleral puncture after vitrectomy; group B (20 eyes), suturing only two upper scleral puncture, but not the lower infusion puncture after vitrectomy; group C (40 eyes), no suturing for all 3 scleral puncture after vitrectomy. All patients underwent 23G vitrectomy only. The corrected visual acuity and IOP were observed after surgery. Results The corrected visual acuity were 0.1 -0.3, 0.2- 0.5, 0.3 -0.8 in one, seven and 14 days after surgery, respectively. No one in group A, B experienced hypotony in one, three, seven and 14 days after surgery. Thirteen (32.5%), five (12.5 %), two eyes (5.0%) in group C experienced hypotony in one, three and seven days after surgery. Seven eyes (17.5%) experienced severe hypotony (＜5 mm Hg) in 14 day after surgery in group C. The difference was statistically significant compared the incidence of hypotony in group C with group A, B respectively at different time points after surgery (chi;2= 16.82,P=0.007). The difference was statistically significant compared the incidence of hypotony in group C at different time points after surgery (chi;2=11.64,P=0.003). The difference was no significant compared the IOP between group A and B at different time points after surgery (F=1.618,P=0.205). Compared the IOP of group C to group A and B, the difference was statistically significant in one and three days after vitrectomy (F=9.351,P=0.000); but not statistically significant in seven and 14 days after vitrectomy(F=0.460,P=0.633). Conclusions Whether or not suturing the scleral punctures is closely related to postoperative hypotony in 23G vitrectomy. Suturing only the two upper scleral punctures can reduce the occurrence of postoperative hypotony.
