  • Clinical outcomes of idiopathic macular epiretinal membrane removal by 23G vitrectomy with or without internal limiting membrane peeling

    ObjectiveTo evaluate the clinical outcomes of idiopathic macular epiretinal membrane (IMEM) by 23G vitrectomy with or without internal limiting membrane peeling. MethodsA total of 40 eyes in 40 patients diagnosed as IMEM underwent 23G pars plana three-port vitrectomy (23G PPV). The macular ERM alone was removed in 20 eyes (non-ILM peeling group). Both ERM and ILM peeling were performed in another 20 eyes (ILM peeling group). All patients underwent removal of ERM with assistance of triamcinolone acetonide. For patients who underwent ILM peeling, indocyanine green dye was used to stain the ILM. ILM was peeled off up to the marginal of macular vessels arch. The patients in ILM peeling group and non-ILM peeling group had postsurgical follow-up for (15.85±3.79) months and (16.45±3.72) months respectively. There were no significant differences in gender, age, OD/OS, preoperative best-corrected visual acuity (BCVA), preoperative central macular thickness (CMT), preoperative total macular volume (TMV) and follow-up time between the two groups (P > 0.05). Intraoperative or postoperative complication was recorded during the follow-up period. At the final visit, the differences in BCVA, CMT and TMV between the two groups were analyzed, so did the correlations between BCVA and CMT or TMV in each group at the same time. ResultsThere was no recurrence of an ERM or severe complications, such as retinal detachment and endophthalmitis in either group. The mean BCVA of ILM peeling group and non-ILM peeling group was 0.53±0.27 and 0.54±0.26 respectively at the final visit. Postoperative BCVA improved significantly in both groups with significant difference (t=5.035, 4.964; P < 0.05). The was no difference of postoperative BCVA between two groups (t=0.176, P > 0.05). The mean CMT was (343.55±48.74) μm and (311.70±42.48) μm, and the mean TMV was (7.78±0.40) mm3 and (7.88±0.43) mm3. CMT (t=9.508, 8.549) and TMV (t=11.098、15.372) revealed a significant decrease in both groups with significant difference (P < 0.05).The postoperative CMT in the ILM peeling group was significantly higher than that in the non-ILM peeling group (t=-2.203, P < 0.05). No difference was found between the two groups in terms of TMV (t=0.755, P > 0.05). Furthermore, no correlation was observed between postoperative BCVA and CMT (r=0.244, 0.266; P > 0.05) or TMV (r=-0.096, 0.157; P > 0.05). Conclusions23G PPV combined with or without ILM peeling is an efficient and safe treatment for IMEM. ILM peeling appears to have similar effect on the long-term visual outcomes comparing with non-ILM peeling, combined with much thicker postoperative CMT.

  • New insight into application and function of air or gas for vitreoretinal surgery

    At present, tamponade agent which being used in retinal surgery is mainly sterile air, gas and silicone oil. Sterile air is mostly used in the treatment of simple retinal detachment. Gas or silicone oil as tamponade is greatly applied for complicated retinal detachment. In recent years, with the application of micro-invasive vitrectomy under a wide-angle viewing system and perioperative anti-vascular endothelial growth factor drugs, application of intraocular filling materials also has changed. The application of silicone oil is significantly reduced. Percentage rate of gas as tamponade for retinal detachment is reduced. The application of sterile air as tamponade is rising. With selecting indication carefully and picking up the suitable air or gas, doctor will reduce the workload. It will also reduce the social burden and benefit patients.

  • Comparison of modified 23G with suturing incision and traditional 23G vitrectomy for silicone oil removal

    ObjectiveTo compare the safety and efficacy of a modified 23G with suturing incision and traditional 23G vitrectomy for silicone oil removal. MethodsA total of 177 patients (180 eyes) who underwent silicon oil removal (the average tamponade period was 4.5 months) were enrolled in this prospective study. The patients included 112 males (113) and 65 female (67). The mean age was (43.8±10.3) years. The corrected vision, indirect ophthalmoscopy, intraocular pressure, B-ultrasound and optical coherence tomography were measured for all patients. All patients had no complete retinal detachment. The patients were randomly divided into modified 23G with suturing incision group (group A, 88 eyes) and traditional 23G vitrectomy (group B, 92 eyes). The differences of sex (χ2=1.596), age, corrected vision (t=0.785), intraocular pressure (t=0.352), primary disease (χ2=1.982) and lens condition (χ2=2.605) were not significant (P>0.05). The operation time, intraocular pressure, silicon oil retention, choroidal detachment, retinal redetachment and endoophthalmitis were recorded at the end of the operation. ResultsThe difference of mean operation time was not significant between group A and B (t=1.950,P>0.05). The differences of mean visual acuity 1 day, 1 week and 3 months after operation were not significant between group A and B (t=0.873, 1.115, 0.141; P>0.05). There was difference of mean intraocular pressure at 1 day after operation (t=2.550,P<0.05), but not at 1 week and 3 months after operation (t=1.451,1.062; P>0.05) between group A and B. There were 25 eyes (28.4%) with intraocular hypotension, 8 eyes (9.1%) with choroidal detachment, 5 eyes (5.7%) with vitreous hemorrhage, 9 eyes (10.2%) with retinal redetachment, and 7 eyes (8.0%) with silicon oil retention in group A. There were 5 eyes (5.4%) with intraocular hypotension, 2 eyes (2.2%) with choroidal detachment, 2 eyes (2.2%) with vitreous hemorrhage, 8 eyes (8.7%) with retinal redetachment, and 1 eye (1.1%) with silicon oil retention in group B. The differences of incidence of intraocular hypotension, choroidal detachment and silicon oil retention were significant (P<0.05). No endoophthalmitis occurred. ConclusionThe safety of modified 23G with suturing incision is better than traditional 23G vitrectomy for silicone oil removal, with decreased incidence of intraocular hypotension, choroidal detachment and silicon oil retention.

  • Effectiveness and safety of multi-artery graft strategy for coronary bypass with small incision in the left chest for 64 patients

    ObjectiveTo investigate the safety and effectiveness of the multi-artery graf tstrategy for coronary bypass (MICS-CABG) with small incision in the left chest, and to provide experience for the promotion of this technique.MethodsThe clinical data of 64 patients with MICS-CABG in Department of Cardiac Surgery of Peking University Third Hospital from December 2015 to November 2019 were retrospectively analyzed. There were 54 males and 10 females, aged 36-77 (61.1±8.7) years. The left lateral thoracic incision (5-8 cm) was made through the 5th intercostal incision, and the operation was performed under off-pump CABG. With the help of the chest wall suspension device and the heart fixator, the proximal anastomosis of the ascending aorta, anastomosis of the target vessels of the  left anterior descending (LAD), left circumflex (LCX) and right coronary artery (RCA) systems were completed. The number of grafts was 2-4 (2.3±0.5) including 2 grafts in 45 patients, 3 grafts in 17 patients and 4 grafts in 2 patients. Three patients were treated with percutaneous intervention (PCI) hybridization and 62 patients were treated with total artery bypass graft. Coronary angiography was performed within 7 days after the operation to evaluate the graft patency rate. The incidence of major adverse cardiac and cerebrovascular events (MACCE) was recorded in the follow-up. The MACCE rate was calculated by Kaplan-Meier method.ResultsNone of the patients was transferred to thoracotomy and no intra-aortic balloon counterpulsation (IABP) or extracorporeal membrane oxygenation (ECMO) was used during the operation. Incision infection was in 1 patient and reoperation in 2 patients (all were postoperative hemorrhage). Within 30 days after surgery, MACCE occurred in 1 patient, including 1 patient of non-fatal myocardial infarction. The overall patency rate of angiography bypass was 96.2%, and the patency rate of anterior descending branch bypass was 98.2%. Follow-up was performed from 12 to 60 months (median follow-up time was 28 months). The loss rate was 7.8% (5/64). The incidence of MACCE was 84.9% (95%CI 79.5%-90.3%).ConclusionThe MICS-CABG can achieve completed re-vascularization and totally artery-CABG and the short-term and medium-term clinical results of the operation are good.

  • Robot-assisted Lobectomy for Non-Small Cell Lung Cancer

    Objective To summarize our initial experience in robot-assisted lobectomy for the treatment of non-small cell lung cancer (NSCLC). Methods A total of 20 NSCLC patients underwent robot-assisted pulmonary lobectomy in General Hospital of Shenyang Military Command from March to September 2012. There were 13 males and 7 females, and their age was 43-80 (60.40±8.07) years. Single-direction thoracoscopic lobectomy technique was used,and systemic mediastinal and hilar lymph node dissection was routinely performed during the operation. There were 4 right upper lobectomies,7 right lower lobectomies,1 right middle lobectomy,7 left lower lobectomies,and 1 left upper lobectomy. Results Postoperative pathological examination showed adenocarcinoma in 12 patients,squamous cell carcinoma in 5 patients,adenosquamous carcinoma in 2 patients,and mucoepidermoid carcinoma in 1 patient. One patient undergoing left upper lobectomy had intraoperative pulmonary artery bleeding of 500 ml,who was healed by pulmonary artery repair via an accessory small incision and blood transfusion of 400 ml. All the other 19 patients successfully underwent robot-assisted lobectomy with their mean intraoperative blood loss of 60.00±42.95 (10-200) ml, and no blood transfusion was needed for them. All the patients were successfully extubated after operation, and none of the patients had severe postoperative complication. The mean thoracic drainage time was 9.35±3.48 (3-15) days. All the patients were discharged uneventfully and followed up for 2-9 (6.01±2.09) months without recurrence or metastasis. Conclusions Robot-assisted pulmonary lobectomy using Da Vinci S Surgical System is safe and feasible,and especially advantageous for lymph node dissection. It can be used for the treatment of early stage NSCLC.
