In order to find out the causes, diagnosis, and the prevention and treatment of vascular crisis following anastomosis of small vessels, 314 cases vascular crisis from 1985 to 1997, were analyzed, in which 152 cases, suffered from tissue necrosis either total or partial, making up 48.4%. One hundred and forty-four cases underwent conservative treatment occupying 45.8% and 104 cases had tissue necrosis, occupying 68.4%. Operative exploration was done on 170 cases, occupying 54.1% and 48 cases of them suffered from necrosis, which made up 31.6% of all necrotic cases. Eighty-six cases were followed up by regular visits, ranging from 40 days to 7 years, with the finding that those who had regained normal circulation after vascular crisis recovered as well as those without crisis, and among those who did not regain normal circulation but survived with the help of collateral circulation after vascular crisis, they were usually cases of bad union, healing of wound, persistent swelling, different degree of tissue atrophy, poor recovery of sensation. It was concluded that proper use of vascular anastomosis technique and prophylactic measures preventing postoperative vascular spasm were extremely important, in the prevention of development of vascular crisis following anastomosis of small vessels. If vascular crisis did not respond well to conservative treatment, prompt surgical exploration should be undertaken.
ObjectiveTo overview the systematic reviews on the timing of different surgical interventions for severe multidrug-resistant pulmonary tuberculosis patients.MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases were searched for systematic reviews about the timing of different surgical interventions for severe multidrug-resistant pulmonary tuberculosis patients from inception to December, 2018. Two reviewers independently screened literature, extracted data, evaluated the reporting and methodological qualities using the PRISMA checklist and the AMSTAR tool. After re-extraction of individual RCT data from included systematic reviews, meta-analysis was performed by Stata10.0 software.ResultsA total of 11 systematic reviews were included. The average methodological quality score was 8.13 in AMSTAR , the reporting quality score was from 19.5 to 25 in PRISMA. Re-performed meta-analysis showed that, the total success rate of operation was 93.3% (95%CI 92.9 to 93.8), the failure rate was 3.7% (95%CI 3.3 to 4.0), the mortality rate was 2.0% (95%CI 1.8 to 2.2), and the loss rate was 1.0% (95%CI 0.8 to 1.2). The cure rates of different surgical methods were all over 80%, among which single lobectomy (98.47%) and compound lobectomy (98.94%) had the higher cure rates than others. For the time of different surgical interventions, cure rate could be improved obviously in patients receiving surgery treatment after 1 months (OR=1.58, 95%CI 1.29 to 1.94, P=0.000 12), 1-8months (OR=1.66, 95%CI 1.30 to 2.12, P=0.000 05) and 9-24 months (OR=1.48, 95%CI 1.15 to 1.90, P=0.002) of anti-tuberculosis therapy compared with 0 month.There were significant differences between two groups.ConclusionCurrent evidence shows that operation is an effective way for severe multidrug-resistant pulmonary tuberculosis. Operative opportunity should be selected after 1-24 months of anti-tuberculosis drug treatment when the operation time depending on whether the tuberculosis has turned negative or not. Operative mode should be decided by the location and the scope of the lesion, which ensures the maximum excision of lesions and retention of lung function.
Objectives To investigate the association of anesthesia recovery time and bispectral index (BIS) monitoring after gastrointestinal surgeries under general anesthesia. Methods A total of 404 cases of selective gastrointestinal surgeries under general anesthesia with BIS monitoring in West China Hospital of Sichuan University from January 2016 to June 2016 were retrieved from anesthesia medical record system as BIS monitoring exposure cohort (group BIS). In addition, 404 cases of selective gastrointestinal surgeries without BIS monitoring were matched as none BIS monitoring exposure cohort (group non-BIS). The primary outcome was the anesthesia recovery time, including the time from the end of surgery to endotracheal extubation (t1) and exiting the operation room (t2). A sub-group analysis was conducted based on patients’ age, length of operation time (t0) and type of surgery(open surgeries vs laparoscopic surgeries). Results The gender, age, body weight and ASA categories between two groups had no significant differences (P>0.05). The length of operation time also had no significant differences between two groups (P>0.05). The extubation time (10.1±4.4vs. 16.4±6.8) and OR exiting time (21.7±12.3 vs. 27.4±14.6) in group BIS were shorter than those in group non-BIS (P<0.05). This difference was markedly significant among elderly patients (age>60) or patients undergoing long operations (operation time>5hours). Among each group, the recovery time had no significant difference between open surgeries and laparoscopic surgeries. Conclusions There is an association between BIS monitoring and shorter anesthesia recovery time in gastrointestinal surgery, including the time of endotracheal extubation and exiting the operation room. BIS monitoring enhances anesthesia recovery among elderly patients and patients undergoing long-lasting operations in particular. There is no significant difference in anesthesia recovery time between open surgeries and laparoscopic surgeries.
Open-globe injuries (OGI) result in complicated and diverse conditions with different mechanisms and anatomical locations, which lead to completely different outcomes based on when to perform pars plana vitrectomy (PPV) after trauma. The PPV operation time points are generally divided into early (0 - 3 days), delayed (4 - 14 days), and late (> 2 weeks). There are still some controversies about the PPV time points after OGI. Injuries with intraocular foreign bodies or high risk of infection usually need early surgery to reduce the occurrence of endophthalmitis. However corneal edema and vitreous hemorrhage can increase the difficulties for early diagnosis and surgery. If there is choroidal hemorrhage or severe trauma in the back part of the eye, delayed intervention can allow the blood clots to be liquefied and removed easily. But there is higher incidence of postoperative complications. Late surgery can reduce the difficulty of PPV, but the increased incidence of proliferative vitreoretinopathy may lead to severe retinal traction, tears and postoperative scar formation.
Objective To evaluate the therapeutic effect of vitreo-retinal surgery on oclular siderosis. Methods The clinical data of 22 patinets (22 eyes) with ocular siderosis due to the magnetic foreign body at intraocular postsegment were retrospectively analyzed. The patients aged from 6 to 54 years (average 40 years), including 21 males and 1 femal. The duration of the magnetic foreign body remained in the eye lasted for 1 month to 20 years. The preoperative best corrected visual acuity (BCVA) was ＜0.01 in 15 eyes, 0.01-0.15 in 5 eyes and 0.1-0.2 in 2 eyes. There was Intra-vitreous foreign body in 18 eyes and ocular wall embedded foreign body in 4 eyes; intraocular foreign body (IOFB) combined with cataract in 18 eyes; combined with retinal detachment in 3 eyes; scleral buckling combined with silicon oil filled in 12 eyes and C3F8 filled in 7 eyes. Cataract extraction was performed in 12 eyes, and 2 eyes underwent filtrating surgery. Results The IOFB was successfully removed by one-off surgery in 22 eyes. BCVA increased in 20 eyes (90.9％) and kept unchanged in 2 eyes (9.1%), including＜0.1 in 7 eyes, 0.1-0.4 in 8 eyes, and 0.5-1.0 in 7 eyes. Operative complications involved retinal holes with retinal detachment in 2 eyes and vitreous haemorrhage secondary to enlarge sclera incision in 2 eyes. Postoperative complications included secondary cataract in 4 eyes, retinal detachment due to silicon oil removal 3 months after submacular removal of foreign body in 1 eye, and retinal detachment 7 days after C3F8 filling in 1 eye; the latter two eyes had reattached retina after another silicon oil filling. At the end of the follow-up period, retina reattached in 22 eyes. Conclusion Advanced modern vireoretinal operation is effective on oclular siderosis, which can avoid the release of Fe+ and improve the patientsprime; visual function.
Objective To compare the predicted efficiency of macular hole closure index (MHCI) calculated by 2 different methods for postoperative anatomical outcomes after idiopathic macular hole (MH) surgery. Methods This is a prospective exploratory clinical study. A total of 63 patients (63 eyes) with idiopathic MH, who received vitrectomy, inner limiting membrane peeling and gas tamponade, were enrolled in this study. All the patients received optical coherence tomography (OCT) examination at each visit to measure the MHCI using the formula MHCI=（M+N）/BASE, M and N is the distance from outer limiting membrane break points to the beginning points of detached photoreceptor from retinal pigment epithelium of both side of the hole, respectively. BASE is the length of MH base. MHCI1 was measured by built-in caliper of OCT software, MHCI2 was measured by ImageJ software. The minimum macular diameter (MHD) was measured by built-in caliper of OCT software. Based on the OCT images, the anatomical outcomes were classified grade A (bridge-like shape closure), grade B (complete closure) and grade C (poor closure). Grade A and B are considered as good closure, grade C as poor closure. Patients were followed up at 3, 6 and 12 months after surgery. The closure grades at last visit were the final outcome. The relationship between MHCI1, MHCI2 and closure grades was analyzed. And the predicted efficiency of MHD, MHCI1 and MHCI2 for anatomical outcomes after the surgery was studied. Results The mean MHCI1 was 0.68±0.21 (0.30-1.35), MHCI2 was 0.95±0.26 (0.41-1.55), and MHD was (476.24±210.18) μm (127-956 μm). MHCI1 and MHCI2 were both negative correlated with the closure grades (r=−0.665, −0.691; P＜0.001). The receiver operating characteristic (ROC) curve analysis of MHCI1, MHCI2 and MHD for the prediction of good or poor closure showed that area under the curve (AUC) was 0.928, 0.957 and 0.916 respectively, and 0.505, 0.67 and 559 μm were set as the lower cut-off value. The sensitivity was 96.2%, 92.3% and 90.9% respectively, and specificity was 81.8%, 72.7% and 76.9% respectively. Accordingly, the ROC curve analysis for the prediction of grade A or B closure showed that AUC was 0.840, 0.847 and 0.653 respectively, and 0.705, 0.965 and 364 μm were set as the upper cut-off value. The sensitivity was 80.0%, 82.9%, 63.4% respectively and specificity was 75.0%, 85.7%, 65.9%. Conclusion MHCI1 and MHCI2, measured by built-in caliper of OCT software or ImageJ software, both have good predictive efficiency for the anatomical outcomes of MH surgery.
ObjectiveTo summarize and analyze the experience of subarterial ventricular septal defect (VSD) repaired with simple pulmonary artery approach.MethodsWe retrospectively anlyzed the clinical data of 102 patients with subarterial VSD repaired with simple pulmonary artery approach in our hospital from August 2015 to October 2018. There were 67 males and 35 females at median age of 3 years (ranging 4 months to 49 years).ResultsThe median operation time was 82 (54-136) min. Median cardiopulmonary bypass time was 36 (21-62) min. The median aortic cross-clamping time was 13 (7-32) min. Thirty two patients of tracheal intubation were removed from the fast-track operating room immediately after surgery. Of the 102 patients, 67 patients underwent a small incision in the lower sternum. The median postoperative ICU stay time was 26 (13-36) h. There was no planned reoperations and no early death.ConclusionSimple pulmonary artery approach for subarterial ventricular septal defect repair with less intracardiac procedures, short operation time, less trauma, quick postoperative recovery has certain advantages in the application of specific groups.
ObjectiveTo explore the clinical effect and safety of laparoscopic cytoreductive surgery combined with gestrinone in the treatment of adenomyosis. MethodsWe retrospectively analyzed the clinical data of 82 patients with adenomyosis who accepted treatment in our hospital from January 2008 to April 2011. According to different treatment method, the patients were divided into three groups. Twenty-seven patients in the treatment group underwent laparoscopic cytoreductive surgery combined with postoperative treatment with gestrinone. For the 25 patients in the surgery group, only laparoscopic cytoreductive surgery was performed, and 30 other patients who only received oral gestrinone were designated as the medicine group. Dysmenorrhea, menstrual volume, uterine size, serum carcinoembryonic antigen 125 (CA125), anemia, and drug side effects were respectively recorded before and after surgery. ResultsThe dysmenorrhea degree reduced significantly in all the three groups. There was no significant difference in the degree of dysmenorrhea, menstrual volume, and uterine volume between the treatment group and the surgery group (P>0.05); the dysmenorrhea degree was significantly different between the treatment group and the medicine group (P<0.05); the differences in hemoglobin levels and the serum CA125 level between the treatment group and the surgery group 12 months later were significant (P=0.019, P=0.049). ConclusionThe laparoscopic cytoreductive surgery combined with gestrinone in treating adenomyosis can improve recent curative effect and provide more effective symptom control compared with surgery alone.
Objective To expound the progress of the reparative and reconstructive surgery (RRS), especially in the recent 20 years, and the developmental direction in the future. Methods We reviewed the information from many books, journals, and conference compilations concerned with RRS. Results RRS emerged with modern surgery. After its development for 20 years, distinguished achievements were obtained in technologies, e.g., biological fixation of bone fracture, bioactive materials, stem cells, tissue engineering, bioactive factor, and induction/ derivation regeneration of tissues and organs. Moreover, ideas were continuously refreshed in RRS, such as emphasis on the equal importance of donor and recipient in autologous transplantation, and of structural and functional restoration in dentofacial surgery. Conclusion Further research programs should be conducted, especially in the fields of creative theories, innovative techniques, and rehabilitation engineering.
ObjectiveTo observe the clinical effect of microincision vitreoretinal surgery (VRS) assisted with intravitreal injection of ranibizumab (IVR) in severe proliferative diabetic retinopathy (PDR) treatment. MethodsThis is a prospective non-randomized controlled clinical study. A total of 60 patients (70 eyes) with severe PDR diagnosed were enrolled and divided into IVR group (31 patients, 35 eyes) and control group (29 patients, 35 eyes). IVR group patients received an intravitreal injection of 0.05 ml ranibizumab solution (10 mg/ml) first, and 3 or 4 days later they received 23G microincision VRS. Control group patients only received 23G microincision VRS. The follow-up time was 3 to 12 months with an average of (4.5±1.8) months. The logarithm of the minimal angle of resolution (logMAR) best corrected visual acuity (BCVA), intraocular pressure, the central retinal thickness (CRT) and retinal reattachment, and the incidence of postoperative complications were comparatively analyzed. ResultsThere was no topical and systemic adverse reactions associated with the drug after injection in IVR group. The incidence of post-operative vitreous hemorrhage (VH) in IVR group and control group was 8.6% and 28.6% at 1 week after surgery, 0.0% and 17.1% at 1 month after surgery, 0.0% and 8.6% at 3 month after surgery respectively. The differences were statistically significant for 1 week (χ2=4.63, P < 0.05) and 1 month (χ2=4.56, P < 0.05), but was not statistically significant for 3 months (χ2=0.24, P > 0.05). The mean post-operative logMAR BCVA of IVR group (0.81±0.40) and control group (1.05±0.42) have all improved than their pre-operative BCVA, the difference was statistically significant (t=12.78, 4.39; P < 0.05). The mean logMAR BCVA of IVR group is higher than BCVA of control group, the difference was statistically significant (t=-2.36, P < 0.05). The average post-operative CRT in IVR group was thinner than that of control group, the difference was statistically significant (t=-2.53, P < 0.05). The incidence of a transient high intraocular pressure in IVR group (14.3%) was lower than that in control group (34.3%), the difference was statistically significant (t=4.79, P < 0.05). The incidence of retinal reattachment (t=0.35), epiretinal membrane (χ2=0.97), neovascular glaucoma (χ2=0.51) was no difference between these two groups (P > 0.05). ConclusionThe minimally invasive VRS assisted by IVR treatment for severe PDR can effectively prevent postoperative VH, reduce CRT and improve visual acuity.
