ObjectiveTo review the current development in therapy of congenital funnel chest. MethodsRecent literature concerning the development of the treatment method for congenital funnel chest was extensively reviewed and summarized. ResultsThe main therapies for congenital funnel chest are thoracoplasty (Ravitch sternum elevation procedure and minimal invasive Nuss procedure) and prosthesis implantation. The magnetic mini-mover procedure and the vacuum bell are still in the research phase. ConclusionBesides the improvement in function, the requirement in appearance after surgery is also improved in the treatment of congenital funnel chest. The minimally invasive surgery and non-invasive procedures could be expected in the future.
Objective To investigate the application value of intraoperative CT navigation in posterior thoracic pedicle screw placement for scoliosis patients. Methods Between October 2009 and December 2011, 46 patients with scoliosis were treated with thoracic pedicle screw placement under intraoperative CT navigation in 21 cases (group A) or under C-arm fluoroscopy in 25 cases (group B). There was no significant difference in age, gender, type of scoliosis, involved segment, and Cobb angle of main thoracic curve between 2 groups (P gt; 0.05). A total of 273 thoracic pedicle screws were placed in group A and 308 screws in group B. The pedicle screw position evaluated and classified by intraoperative CT images according to the Modi et al. method; and the accurate rate, the safe rate, and the potential risk rate of pedicle screws were calculated on the upper thoracic spine (T1-4), the middle thoracic spine (T5-8), the lower thoracic spine (T9-12), and the entire thoracic spine (T1-12). The accuracy and security of thoracic pedicle screw placement were compared between 2 groups. Results On the entire thoracic spine, the accurate rate of group A (93.4%) was significantly higher than that of group B (83.8%), the safe rate of group A (98.9%) was significantly higher than that of group B (92.5%), showing significant differences between 2 groups (P lt; 0.05). However, the potential risk rate of group B (7.5%) was significantly higher than that of group A (1.1%) (P lt; 0.05). On the upper, the middle, and the lower thoracic spines, there was no significant difference in the accurate rate, the safe rate, and the potential risk rate of pedicle screws between 2 groups (P gt; 0.05). According to CT evaluation results, the potential risk pedicle screws were revised or removed during operation. The patients of 2 groups had no neurological deficits through physical examination of nervous system at 3 days after operation. Conclusion Intraoperative CT navigation can improve the accuracy and security of posterior thoracic pedicle screw placement and it can ensure the safety of operation by finding and promptly removing or revising the potential risk pedicle screws.
Objective Surgical repair for giant lower ventral hernia is facing challenge owing to enormous tissue defect and the critical structures of pubis and il iac vessels. To investigate the method and curative effect of intraperitoneal onlay mesh (IPOM) combined with Sublay for compound repair of giant lower ventral hernia. Methods Between November 2008 and August 2010, 26 patients with giant lower ventral hernia were treated. There were 15 males and 11 females with an averageage of 61 years (range, 36-85 years), including 11 cases of lower midl ine incisional hernia due to radical rectal procedures, 6 cases of Pfannenstiel incisional hernia due to radical uterectomy, and 9 cases of lower midl ine incisional hernia due to radical cystectomy. Of them, 11 patients underwent previous repair procedures. The mean time from hernia to admission was 8.5 years (range, 1-15 years). All hernias were defined as M3-4-5W3 according to classification criteria of Europe Hernia Society. The mean longest diameter was 17.5 cm (range, 13-21 cm) preoperatively. Before 2 weeks of operation, abdominal binder was tightened gradually until the contents of hernia sac were reduced totally, and then reconstruction of abdominal wall was performed with compound repair of IPOM and Sublay technique. Results All of compound repair procedures were performed successfully. The mean hernia size was 112.5 cm2 (range, 76.2-160.6 cm2); the mean polypropylene mesh size was 120.4 cm2 (range, 75.3-170.5 cm2); and the mean compound mesh size was 220.0 cm2 (range, 130.4-305.3 cm2). The mean operative time was 155.5 minutes (range, 105.0-195.0 minutes) and the mean postoperative hospital ization time were 12 days (range, 7-16 days). Incisions healed by first intention; 4 seromas (15.4%) and 3 chronic pains (11.5%) occurred and were cured after symptomatic treatment. All patients were followed up 3-24 months (mean, 14.5 months). No recurrence and any other discomforts related to repair procedure occurred. Conclusion Compound repair of IPOM and Sublay is a safe and efficient surgical procedure for giant lower ventral hernia, owing to its characteristics of adequate patch overlap and low recurrence rate. Perioperative management and operative technology play the key role in the success of repair procedure.
Objective To observe the incidence and related factors of macula hole retinal detachment（MHRD）after phacoemulsification cataract extraction and intraocular lens（IOL）implantation. Methods The clinical data of 10 076 patients(13 625 eyes) who underwent phacoemulsification cataract extraction and intraocular lens implantation were retrospectively analyzed. There are 1228 patients (1853 eyes) with high myopia. All the patients were examined by routine slitlamp microscopy, ophthalmoscopy as well as A- or B-scan ultrasonography. The phacoemulsification cataract extraction with transparent cornea incision or scleral tunnel incision, combined with intraocular lens implantation was performed in all the patients. The followup was ranged from 12 to 126 months, with a mean of （48.2plusmn;31.1）months. The MHRD was confirmed by the examinations of the fundus, B-scan ultrasonography and optical coherence tomography. The incidence of postoperative MHRD and the risk factors were analyzed. Results 10/13 625 eyes (0.073％) with MHRD were observed. 7/1853 high myopia eyes (0.378%) with MHRD were observed. The occurrence time of MHRD was ranged from 9 to 74 months after surgery, with a mean of 38.5 months. The cumulative risk was estimated at 0.16％ (95% confidence interval, 0.05% -0.27%).Conclusions The incidence of MHRD after phacoemulsification cataract extraction combined with intraocular lens implantation is 0073%. The MHRD incidence of high myopia eyes is 0.378%. High myopia may be the risk factor for MHRD.
Objective To observe the clinical characteristics and therapeutic effect of aphakic retinal detachment (ARD) eyes and pseudophakic retinal detachment (PPRD) eyes.Methods The clinical data of 805 patients,including 321 ARD and 484 PPRD eyes were retrospectively analyzed.The patientsprime;visiual acuity, refraction, intraocular pressure were examined, and the patients also underwent slit lamp microscopy and direct and (or) indirect ophthalmoscopy.The preoperative bestcorrected visual acuity (BCVA) was between light perception (LP) and 0.6.Mainly according to the PVR grade and retinal holes position to take the scleral buckling or vitrectomy combined with scleral buckling. The 805 eyes were divided into 1995-1999 group (243 eyes) and 20002007 group (562 eyes) according to operative time.The follow-up ranged from 3 to 25 months, with an average of 12.3 months.The success standard of surgery was set as anatomic retinal reattachment and the last follow-up time was considered as the judgment time.The surgical complications were recorded at each followup time points. The composition of PPRD,the visual acuity,ocular lesions, surgical methods and results before operation and visual acuity after operation in two groups were analyzed and compared by MantelHaenszel chisquare test. Results The average interval from lens extraction to RD occurrence was 15.4 months in PPRD eyes and 39.1 months in ARD eyes. The final total anatomic success rate was 95.9%, and was 93.5% in the scleral buckle eyes and 97.2% in vitrectomy eyes.The BCVA was better than 0.3 after operation only in 11.9% of the 805 patiens,and the visual acuity increased more than 2 lines in 67.3%. Compared with the ARD eyes,early onset, high proportion of total posterior vitreous detachment,severe PVR,wide RD range,low detection rate of retinal hole and low antomic success rate were found in PPRD eyes.Compared with the 1995-1999 group,the proportion of vitreous surgery,anatomic success rate and better visual acuity were found in 2000-2007 group.Conclusions The ocular lesions of ARD and PPRD is more complicated,the therapeutic effect are improving in recent years.
In 31 eyes having undertaken intraocular lens(I0L)implantation with vitreous loss, closed system automated anterior vitrectomy was performed.Corrected visual acuty of 0.5 or better was 68% after follow-up of 8.8 months.The result showed that automated anterior vitrectomy furnished beneficial condition to posterior chamber I0L implantation. （Chin J Ocul Fundus Dis,1996,12: 25- 26）
