Objective To summarize the experiences of surgical treatment of sinus venosus atrial septal defect （SVASD）. Methods There were 32 patients of SVASD, all of them were associated with totally or partially right anomalous pulmonary venous connection. There were 25 cases of superior SVASD, 22 cases underwent double-patch procedure, 3 cases underwent Warden procedure. In 7 cases of inferier SVASD, 3 cases of Scimitar syndrome underwent ASD repair by pericardial patch and at the same time the anomalous pulmonary vein was divided and reimplanted to the posterior wall of left atrium, 4 cases of them underwent single-patch ASD repair. Results The surgical results were satisfying and no patient died, 28 patients were in sinus rhythm and echocardiography showed neither obstruction of caval vein and right pulmonary vein nor residual interatrial shunt. Conclusion SVASD mostly associated with right anomalous pulmonary venous connection according to its special anatomic structure. Preserving the function of sinus node and avoiding of obstruction of caval vein should be routinely considered when superior SVASD was repaired. The heart function of Scimitar syndrome should be followed-up for a long time for it usually associated with right lung hypoplasia.
Objective To evaluate the safety and ascendancy of small caliber stapler application for anterior resection in ultra-low rectal cancer with anal sphincter preservation. Methods A retrospective analysis of the data of 60 cases of ultra-low rectal cancer treated by anterior resection with anal sphincter preservation by double stapling technique according to TME principle between June 2006 and June 2009 were undertaken. The 60 patients were divided into two groups, each group included 30 cases. One group adopted 33 mm stapler and another group adopted 29 mm stapler, and then the profiles of medi-operation, post-operation, and prognosis were assessed. Results Time of simple anastomose in operation was (9.0±3.3) min in 33 mm stapler group and (6.0±2.6) min in 29 mm stapler group, and there was significant difference between them (P=0.022 5). There were 6 cases needed to be restored because of lesion during operation or dys-anastomosis in 33 mm stapler group, while 2 cases in 29 mm stapler group, there was significant difference between them (P=0.030 1). No significant differences were observed between the two groups in terms of the time for operation, leakage, bleeding, stenosis, anastomotic recurrence, and fecal incontinence after operation or length of stay. Conclusion The application of 29 mm stapler not only can shorten time for anastomose and step down the degree of difficulty, but also dosen’t increase stenostomia and other complications.
Objective To summarize the clinical experiences in treating primary tracheal tumors by surgery, so as to improve the results of surgical treatment. Methods The clinical data concerning 22 surgically treated patients were retrospectively analyzed. Four patients tumor were benign and eighteen cases’s tumor was malignant. Tracheal resections and end to end anastomosis were performed in 14 cases, carinal resection was performed in 4 cases, lateral tracheal wall resection was performed in 1 case, local scrape were performed in 2 cases, tumor was resected transfiberoptic bronchoscopy in 1 case. Tracheal resectable length was from 2.0cm to 5.2cm，and the average resectable length was 3.8cm in operation. Results 17 cases had been misdiagnosised ( 77.3%) in outpatient department. It was easy to be misdiagnosised as asthma. One case died of respiratory failure after operation in 30 days. The complication rate was 31.8%, complications consist of pneumonia in 4 cases, anastomosis leakage in 1 case and chylothorax in 2 cases. Anastomosis stenosis was found in 3 cases, the syndromes were improved after treatment.Twenty cases were followed up from 1 month to 8 years. Four cases with benign tumors were still alive. Among 16 cases with malignant tumors, 6 cases had survived more than 5 years， 3 cases died of brain, liver, bone metastasis of malignant tumors. Conclusion Surgical resection is the most effective treatment of tracheal tumors. Tracheal resection and reconstruction is the main choice of primary tracheal tumors treatment. Benign tumors can be resected conservatively. The reductions of operative complications are the key points of good surgical results. To know the characteristic of primary tracheal tumors well can reduce the misdiagnosis rate.
ObjectiveTo summarize the current advancement of adenocarcinoma of the esophagogastric junction (AEG) and improve the knowledge and cognition about AEG and find a feasible treatment strategy.Method Relevant literatures about current advancement of AEG published domestically and abroad recently were collected and reviewed. Results AEG had obvious differences from other parts of stomach tumors in anatomy, physiology, and pathology. The study of AEG in definition, biology origin, classification, lymph node metastasis and other aspects had basically reached a consensus. But for the surgical approach, the extent of resection, lymph node dissection or the way of the digestive tract reconstruction was controversial for a long time. Conclusions AEG as a kind of independent disease is increasing hazard to human health．By far, the most effective treatment is surgical resection, and how to choose the surgical method needs to be further researched.
Abstract: Objective To summarize onestage repair of coarctation of the aorta(CoA) with intracardiac malformation in infants. Methods From January 2001 to January 2006, 28 patients with CoA and associated intracardiac malformation underwent onestage repair. There were 18 patients with preductal and another 10 patients with juxtaductal CoA. Six patients were accompanied by diffuse hypoplasia of aortic arch and 22 patients were associated with patent ductus arteriosus (PDA). Associated cardiac malformation included ventricular septal defect in 16 patients, ventricular septal defect and atrial septal defect in 5 patients, atrioventricular canal defect in 3 patients, transposition of great artery and ventricular septal defect in 2 patients and double outlet right ventricle in 2 patients. Left posterolateral thoracotomy combined with median sternotomy were used in 12 patients and single median sternotomy was used in 16 patients. End to end anastomosis of aorta with removal of the coarctated segment were performed in 20 patients, Gore-Tex patch graft aortoplasty were performed in 4 patients and aortoplasty with left subclavain flap were performed in 4 patients. Results There was no death.The lasting time of intubation was 7h to 13d, and intensive care unit (ICU) staying time was 3 to 18d. Four patients received delayed sternal closure in 48 to 72h after surgery because of cardiac dilatation. Three patients received peritoneal dialysis for acute renal failure following cardiac surgery. Three patients received inhalation of nitric oxide for treatment of postoperative pulmonary hypertension. The systolic pressure difference between lower limb and upper limb measured after operation was 10 to 20mmHg in 18 patients.There were no obvious systolic pressure difference between arm and leg in 8 patients.The systolic pressure of upper limb was higher than that of lower limb in 2 patients, and the pressure difference was 15mmHg and 20mmHg. All patients were followed up from 3 to 50 months. They were all survival except one died of severe tricuspid regurgitation, pulmonary infection and respiratory failure 3 months after surgery which diagnosis was transposition of great artery and ventricular septal defect. The results of other 27 patients were satisfactory. Recoarctation occurred in 1 patient with end to end anastomosis and 1 patient with Gore-Texpatch graft aortoplasty. The pressure difference through the measurement of echocardiography was 25mmHg and 28mmHg. No reoperation were undergone. Conclusion CoA with intracardiac malformation can be repaired by single median sternotomy or left posterolateral thoracotomy combined with median sternotomy in onestage. This operative approach is beneficial, not only with shorten period of therapy and less operative cost, but also advantageous for the recovery of cardiac and pulmonary function.
ObjectiveTo study the effectiveness of surgical treatment of congenital type V thumb syndactyly. MethodsBetween March 2010 and May 2015, 12 cases of congenital type V thumb syndactyly were treated. There were 7 males and 5 females, aged from 1 to 25 years (mean, 8 years). The right thumb was involved in 8 cases, and the left thumb in 4 cases. There were 2 cases of radial type, and 10 cases of ulnar type. The basement of polydactylism was far away from the carpometacarpal joint in 7 cases, and was close to the carpometacarpal joint in 5 cases (slight ulnar deviation in 1 case). X-ray films showed that the main first thumb metacarpal bone and trapezium fitted well, and 2 cases had the first metacarpal bone deformity. Preoperative individualized treatment plan was made, and polydactylism was excised by the "S" or "Z" incision and simultaneous reconstruction of thenar muscle insertions or adductor muscle insertions was performed; if necessary, wedge osteotomy was used for correction. ResultsAll incisions healed by first intention with no complication. All cases were followed up 6 to 24 months (mean, 12 months). The thumb appearance, flexion and extension, the function of opposition, abduction function were improved significantly in 11 cases with no scar contracture deformity, small first web space, and deviation deformity. One case had slightly narrow first web space. According to hand function criterion, the results were excellent in 10 cases, good in 1 case, poor in 1 case; excellent and good rate was 91.7%. ConclusionBased on the condition of the type V thumb syndactyly, the individualized treatment plan is made, which can better restore the shape and function of the thumb.
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.
ObjectivesTo assess the methodological and reporting quality of surgical meta-analyses published in English in 2014.MethodsAll meta-analyses investigating surgical procedures published in 2014 were selected from PubMed and EMbase. The characteristics of these meta-analyses were collected, and their reporting and methodological quality were assessed by the PRISMA and AMSTAR, respectively. Independent predictive factors associated with these two qualities were evaluated by univariate and multivariate analyses.ResultsA total of 197 meta-analyses covering 10 surgical subspecialties were included. The mean PRISMA and AMSTAR score (by items) were 22.2±2.4 and 7.8±1.2, respectively, and a positive linear correlation was found between them with a R2 of 0.754. Those meta-analyses conducted by the first authors who had previously published meta-analysis was significantly higher in reporting and methodological quality than those who had not (P<0.001). Meanwhile, there were also significant differences in these reporting (P<0.001) and methodological (P<0.001) quality between studies published in Q1 ranked journals and (Q2+Q3) ranked jounals. On multivariate analyses, region of origin (non-Asiavs. Asia), publishing experience of first authors (ever vs. never), rank of publishing journals (Q1 vs. Q2+Q3), and preregistration (presence vs. absence) were associated with better reporting and methodologic quality, independently.ConclusionThe reporting and methodological quality of current surgical meta-analyses remained suboptimal, and first authors' experience and ranking of publishing journals were independently associated with both qualities. Preregistration may be an effective measure to improve the quality of meta-analysis, which deserves more attention from future meta-analysis reviewers.
Objective To observe the related complications of 23G pars plana vitrectomy (PPV). Methods One hundred and fifteen patients who underwent 23G PPV were enrolled in this study. There were 98 patients (65.3%) with macular diseases, 46 patients (30.7%) with proliferative diabetic retinopathy, four patients (2.7%) with vitreous hemorrhage, one patient (0.7%) with rhegmatogenous retinal detachment, and lens nucleus falling off in cataract surgery in one patient (0.7%). Among 98 patients with macular diseases, 21 patients (21.4%) underwent topical anesthesia, 77 patients (78.6%) underwent retrobulbar anesthesia. DORC "twostep method" was performed in three patients, and Alcon 23G PPV "onestep method" was performed in 147 patients. The operation times ranged from 20 to 100 minutes, with a mean of (51.1±18.9) minutes. The follow-up ranged from three to 12 months. The intraoperative and postoperative complications were observed. Results Intraoperative complications was found in seven patients (4.7%), which included iatrogenic retinal breaks in one patient (0.7%), macular damage in one patient (0.7%), suprachoroidal perfusion in one patient (0.7%), puncture leakage and closure incision in two patients (1.3%), vitreous hemorrhage in one patient (0.7%) and stopper broken off in cannula in one patient (0.7%). Postoperative complications was found in 34 patients (22.7%), which including retinal detachment in one patient (0.7%), vitreous hemorrhage in three patients (2.0%), cataract in three patient (2.0%), intraocular pressure ＜10 mm Hg（1 mm Hg=0.133 kPa） in 20 patient (13.3%), and transient ocular hypertension in seven patients (4.7%). After treatment there was no complication associated with surgery. Conclusion Intraoperative complications related to incision and transient hypotony are mainly complications of 23G PPV.
Objective To evaluate the clinical characteristics of end oscopically guided thorough vitrectomy in managing exogenous endophthalmitis with cloudy cornea. Methods The clinical data of 20 patients (20 eyes) suffered from exogenous endophthalmitis with cloudy cornea and underwent endoscopically guided total vitrectomy were retrospectively analyzed. The patients (18 males and 2 females) aged from 5 to 79 years with the average age of 35.9 years. There were 16 post-trauma and 4 post-cataract endophthalmitis. The cornea was cloudy with the visual acuity of not better than counting fingers in all eyes. During the operation, posterior vitreous detachment was induced, vitreous at the base and bands over the ciliary body was removed, and membrane at the anterior or posterior surface of the iris was also removed after lensectomy. The median of the duration of hospita lization to operation was 1.5 days, and the follow-up period was 6～42 months (mean=23 months). Results Positive cultures were obtained in 9 (45%) cases. Seven intraocular foreign bodies were extracted from 6 eyes. Ora serrata was separated at one place in 2 cases, iatrogenic retinal tear at one, two place in 1 case respectively. Vitrectomy and intravitreal injection were underway again in 2 cases respectively after surgery. Ten eyes (50%) retained useful vision (ge;0.05). The visual acuity was decreased, maintained and improved in 1, 3 and 16 eyes, respectively, and 4 cases over than 0.08. Cornea was clear in 11 (55%) eyes after operation; 9 cases with silicon oil in; ocular pressure was slanting low in 2 cases , but more than 5 mm Hg（1 mm Hg=0.133 kPa）; intraocular hypertension in 1 case , controlled by medicine; local and questionable retinal detachment in 1 case respectively, without surgery again. The visual acuity of none of the 9 eyes with silicon oil in was lower than counting fingers, only one eye in 11 eyes without silicon oil in was lower than 0.05 and no eye lost at the end of follow-up. Conclusion Endoscopically guided total vitrectomy is useful, safe and reliable for the management of exogenous endophthalmitis with cloudy cornea in time. （Chin J Ocul Fundus Dis，2008，24：202-205）
