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.
Vitrectomy is the preferred surgical method for diabetic retinopathy, especially in the stage of proliferative diabetic retinopathy. Vitrectomy for diabetic retinopathy involves all aspects of vitrectomy, which is one of the signs of maturity of retinal surgeons. With the application of minimally invasive vitrectomy and perioperative anti-neovascularization drugs, indications and timing of surgery, perioperative medication, management of vitreous, and whether combined with cataract surgery have changed greatly, and new understanding is needed. Evidence-based clinical research on the timing of diabetic retinopathy surgery and perioperative drug use should be carried out to provide a new theoretical basis for the surgical treatment of diabetic retinopathy.
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.
ObjectiveTo explore the risk factors of recurrence of incisional hernia following incisional hernia tension-free repair. MethodsThe clinical data of 162 patients with incisional hernia underwent tension-free repair were retrospectively analyzed in this hospital from January 2005 to January 2011. The relationships of incisional hernia recur-rence to gender, age, body mass index, hernia size, abdominal wall defect site, preoperative chronic comorbidities, type of tension-free repair, operation time, and wound healing disorders were analyzed by univariate and multivariate analysis. ResultsOne hundred and sixty-two patients were followed up 7-70 months with mean 34.5 months. The rate of recur-rence following incisional hernia tension-free repair was 9.26% (15/162). The results of univariate analysis showed that recurrence following incisional hernia tension-free repair was associated with the age (P < 0.05), body mass index (P < 0.05), type of tension-free repair (P < 0.05), hernia size (P < 0.05), and wound healing disorders (P < 0.05). The results of multivariate logistic regression revealed that the body mass index, type of tension-free repair, hernia size, and wound healing disorders were the independent risk factors associated with recurrence following incisional hernia tension-free repair. Fifteen recurrent patients were reperformed successfully. There was no recurrence following up with an average 23 months. ConclusionsIt is necessary to become familiar with the risk factors for recurrence of incisional hernia in order to eliminate or decrease their effects on the positive outcome of incisional herniorrhaphy. The patients with fat, hernia ring bigger, incorrect opera-tion or wound healing disorders might be easy to relapse. Surgical approach should be individualized for recurrence.
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）
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 experiences and methods on reoperation of recurrent incisional hernia after mesh repair with prosthetic patch. Methods Sixteen patients who got reoperation from January 2007 to December 2010 because of recurrent incisional hernia after mesh repair were analyzed retrospectively. Results All patients received prosthetic patch repair for reoperation. Thirteen patients received new mesh repair accompanied with old mesh removal, repair conducted by suturing new mesh with old mesh together in two patients, and repair performed by new mesh overlapping the old mesh in one patient. All patients recovered with primary wound healing. Fluid upon the mesh occurred in 3 patients and cured by percutaneous puncture and pressure dressing. Postoperative hospital stay was 7 to 16 days and the average 9 days. The drainage was removed 2 to 7 days after operation and the average was 4 days. All the 16 patients were followed up. And during a follow-up range of 5 to 36 months and the average 20 months, there was slight foreign body sensation in one patient, no chronic pain in wound area occurred. And no abdominal wall hernia recurrence occurred. Conclusions Reoperation of recurrent incisional hernia after mesh repair need to consider the recurrent position, material of the previous mesh, and the previous surgical methods, and should select appropriate prosthetic patch and surgical procedure, then could gain satisfied results.
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.
Objective To analyze symptoms, associated anomalies, diagnostic approach, and surgical procedures in patients with unroofed coronary sinus syndrome (UCSS), a rare congenital disorder. Methods The clinical, echocardiographic, operative, and followup data on 44 patients with unroofed coronary sinus syndrome (typeⅠin 15，typeⅡin 9，type Ⅲ in 5 and type Ⅳ in 15) between May 1998 and January 2008 were reviewed retrospectively. The initial diagnosis of unroofed coronary sinus syndrome was made by echocardiography in 12 patients, by the surgeon at repair of other congenital cardiac anomalies in 32 patients. The patients underwent cardiovascular surgery at Fu Wai hospital. Left superior vena cava(LSVC) directly drains into the left atrium (LA) were found in 15 cases, LSVC was ligated in 1 case, the intracardiac tunnel to drain LSVC to right atrium (RA) were reconstructed in 14 cases. The associated cardiac lesions were corrected concomitantly. Results There were 3 hospital deaths. One patient died of low cardiac output syndrome and 2 patients died of pulmonary infection. One case was applied diaphragm plication because of right diaphragm paralysis after the heart operation and the hospital stay was 70 days.The other 40 cases had good surgical result. The average time of extubation was 11.7±12.1 h and hospital stay was 8.1±2.8 d. In the 32 cases, who have been followed up from 4 months to 10 years, there was no death and severe complications. Conclusion Unroofed coronary sinus syndromes are often missed in the preoperative evaluation of congenitally malformed hearts. When associated with LSVC, unroofed coronary sinus syndrome should be considered as a possible additional finding.We performed different surgical approaches to deal with the different kinds of LSVC with a good result.
Objective To analyze the strategy and skill of resection for lung cancer invading the superior vena cava (SVC) and improve the surgical treatment results. Methods An analysis of 35 patients who underwent surgery for lung cancer invading the SVC was performed. The pressure of SVC before and during operation, and the time of clamping the SVC were recorded. The conjunctival oedema was observed. 14 mm or 16 mm diameter terylene or expanded polytetrafluoroethylene graft artificial vessel were used to replace SVC.The continuous everted suture was applied with 4-0 Prolene. The embolism of artificial vessel and stomal hemorrhage were observed after operation. Results The SVC replacement with prothesis were performed in 20 patients in which the SVC hadn’t clamped in 5 patients. The clamping time was 8-35 mins for another 15 patients with SVC clamped.The clamping time were 1735 mins and 8-20mins respectively for patients with or without conjunctival oedema.The pressure of SVC was 20-45cmH2O before operation and the maximal pressure was 37-56cmH2O during operation for patients with clamping SVC. The maximal pressure during operation was 48-56cmH2O and 37-47cmH2O for patients with or without conjunctival edema, the difference was significant (P=0.000).No mortality or embolism of artificial vessel,but the stomal hemorrhage was found for one patients cured by reoperation. Thirtytwo patients was followed up for 4-130 months,the median survival time was 35 months. Conclusion No clamping of SVC or short time clamping with some operative skill can avoid the occurrence of cerebral edema. Selecting suitable length and roughness of the expanded polytetrafluoroethylene artificial vessel and continuous everted suture with suitable slide suture is important for avoiding the occurrence of embolism and the stomal hemorrhage.
