Objective To analyze the sutureless technique use in the surgical repair for total anomalous pulmonary venous connection in neonates. Methods Between September 2002 and December 2015, 71 consecutive neonates with supracardiac or infracardiac type total anomalous pulmonary venous connection who underwent surgical repair in our institute were included in this study. There were 57 males and 14 females at median age of 8 (1, 29) d. And the median body weight was 3.3 (2.1, 4.7) kg. There were 45 patients (63.4%) with supracardiac, 26 patients (36.6%) with infracardiac. Patients were divided into two groups: a conventional technique group (29 patients) and a sutureless technique group (42 patients). To control for potential differences in the characteristics of patients between the sutureless technique group and the conventional technique group, the method of propensity-score matching was used. Results Basic characteristics of patients after propensity-score were not different.There were 11 operative deaths (15.5%), 7 late deaths (96.%), total 18 deaths (25.4%). The mortality was 58.6% (17/29) in the conventional technique group, 2.4% (1/42) in the sutureless technique group (P=0.000). Kaplan-Meier survival curve showed a difference in mortality between the two groups (P=0.005). The patients were followed up for 25.5 (1.0-13.0) months.Postoperative anastomotic or pulmonary vein stenosis occurred in 12 patients, 8 of them died at a higher mortality than that of the patients with smooth anastomosis [66.7% (8/12) vs. 16.9% (10/59), P=0.001]. Conclusion The patients who have postoperative anastomotic or pulmonary vein stenosis have higher mortality. Compared with conventional technique, sutureless technique can dramatically decrease the incidence of postoperative anastomotic or pulmonary vein stenosis and the mortality of surgical repair for total anomalous pulmonary venous connection in neonates.
ObjectiveTo analyze clinical outcomes of sutureless technique for patients undergoing surgical correction of total anomalous pulmonary venous connection (TAPVC). MethodsBetween July 2007 and December 2013, 132 consecutive TAPVC patients underwent surgical correction in Guangdong Cardiovascular Institute. Those patients with such associated congenital cardiac anomalies as single ventricle and right atrial isomerism were excluded from this study. All the patients underwent biventricular repair. Preoperatively, all the patients received echocardiography, and most patients received CT scan to know the development of pulmonary veins. Preoperative diagnosis was confirmed by intraoperative exploration. According to different surgical techniques, all the patients were divided to a conventional technique group and a sutureless technique group. In the conventional technique group, there were 69 patients including 54 males (78.3%)and 15 females (21.7%)with their median age of 60 (30, 225)days and median body weight of 4.85 (3.50, 6.35)kg. In the sutureless technique group, there were 63 patients including 48 males (76.20%)and 15 females (23.8%)with their median age of 90 (30, 210)days and median body weight of 4.58 (3.72, 6.20)kg. Follow-up was performed till January 1, 2014. ResultsIn-hospital mortality (4.8% vs. 7.2%, χ2=1.414, P=0.720)and postoperative overall mortality (4.8% vs. 13.0%, χ2=2.733, P=0.098)of the sutureless technique group were both lower than those of the conventional technique group, although there was no statistical difference. Postoperative incidence of pulmonary venous obstruction (PVO)of the sutureless technique group was significantly lower than that of the conventional technique group (1.6% vs. 10.1%, χ2=4.236, P=0.040). Cox proportional-hazards regression showed that conventional technique and preoperative PVO were significant risk factors for postoperative PVO (P=0.023, P=0.016). Conventional technique was not significantly correlated with postoperative mortality (P=0.060). ConclusionSutureless technique can significantly lower postoperative incidence of PVO for patients with supracardiac TAPVC.
ObjectiveTo explore the effectiveness of non-absorbable suture or suture anchor fixation by anterior approach in the treatment of anteromedial facet fractures of the ulnar coronoid process. MethodsBetween February 2007 and February 2012,16 cases of anteromedial facet fractures of the ulnar coronoid process were treated with operation.There were 9 males and 7 females,aged 20-80 years (mean,43.5 years).The causes of injury were traffic accident injury in 7 cases,tumble injury in 5 cases,and falling injury from height in 4 cases.The time from injury to operation was 6.8 days on average (range,2-8 days).All cases had closed fractures.According to O'Driscoll classification,there were 4 cases of type Ⅱ a,7 cases of type Ⅱ b,and 5 cases of type Ⅱ c.Among 16 patients,7 had simple anteromedial facet fractures of the ulnar coronoid process,and 9 had associated injury,including terrible triad in 3,Monteggia fractures in 4,and olecranon fractures in 2.All fractures were fixed with non-absorbable suture in 10 cases,and with suture anchor in 6 cases.The Mayo Elbow Performance Score (MEPS),range of motion (ROM),and complications were used to assess the elbow function. ResultsThe incisions all healed by first intension,without neurovascular injury.Fifteen patients were followed up 10-48 months (mean,25.3 months).The X-ray films showed that all fractures healed,with the mean healing time of 17.5 weeks (range,11-30 weeks).At last follow-up,the mean MEPS score was 88.5(range,55-100);the results were excellent in 10 cases,good in 3 cases,fair in 1 case,and poor in 1 case,with an excellent and good rate of 86.7%.The mean ROM of flexion and extension was 118°(range,35-145°),and the mean ROM of forearm rotation was 138°(range,85-165°).One case had elbow instability,and 3 had slight pain.No heterotopic ossification and traumatic arthritis occurred during the follow-up. ConclusionThe anteromedial facet fractures of the ulnar coronoid process can be clearly exposed through anterior approach,and the fracture fixation using non-absorbable suture and suture anchor fixation usually can restore the elbow function.
Objective To introduce the arthroscopic technique of figure-of-eight suture fixation for tibial eminence fracture, and to report its clinical results. Methods From January 1998 to June 2001, 21 cases of tibial eminence fracture were treated arthroscopically with figure-of-eight suture fixation technique. Active rehabilitation began one week after operation. The patients were followed up 6-24 months. The reduction and union of fracture, knee laxity, range ofmotion, and total knee function were evaluated. Results All fracture healed without displacement six weeks after operation. Three months postoperatively, no knee laxity or instability was detected in all patients; full range of motion of the affected knee returned in all patients when compared with the normal side. Six months postoperatively, the Lysholm knee score was 93.4±2.7. Conclusion Arthroscopic treatment of tibial eminence fracture with figure-of-eight suture fixation technique is reliable for fracture reduction , fixation and early mobilization. Arthroscopy is conducive to diagnoses and treatment of associated knee arthropathy, reduces the morbidity associated with arthrotomy, and restores knee function to the greatest extent when combined with figure-of-eight suture fixationtechniques.
ObjectiveTo summarize the research progress of suture augmentation (SA) in anterior cruciate ligament (ACL) reconstruction. MethodsA comprehensive review of recent literature about SA in ACL reconstruction at home and abroad was conducted. The efficacy of SA in ACL reconstruction was evaluated by examining the definition, biomechanics, and histological studies of SA, along with its clinical application status in ACL reconstruction. ResultsSA demonstrates significant advantages in enhancing the biomechanical stability of ACL grafts, reducing the risk of re-rupture, and accelerating postoperative recovery. Specifically, SA improves graft stiffness, ultimate failure strength, and cyclic stability, thereby diminishing the risk of early postoperative failure and joint instability. Histologically, it fosters remodeling and tendon-bone integration through early load-sharing mechanisms; however, stress shielding may interfere with natural remodeling processes, warranting further attention. Clinically, SA reduces graft failure rates and the need for revision surgeries, markedly improving knee joint stability and functional recovery in young patients. Nevertheless, its impact on graft maturation and potential complications remains controversial. ConclusionDespite the many advantages of SA in ACL reconstruction, future endeavors should focus on optimizing tensioning techniques, developing bioactive materials, and conducting large-scale randomized controlled trials to further elucidate its clinical value and scope of applicability, providing a more reliable solution for ACL reconstruction.
ObjectiveTo investigate the morphological characteristics of the glenohumeral joint (including the glenoid and coracoid) in the Chinese population and determine the feasibility of designing coracoid osteotomy based on the preoperative glenoid defect arc length by constructing glenoid defect models and simulating suture button fixation Latarjet procedure. MethodsTwelve shoulder joint specimens from 6 adult cadavers donated voluntarily were harvested. First, whether the coracoacromial ligament and conjoint tendon connected was anatomically observed and their intersection point was identified. The vertical distance from the intersection point to the coracoid, the maximum allowable osteotomy length starting from the intersection point, and the maximum osteotomy angle were measured. Next, the anteroinferior glenoid defect models of different degrees were randomly constructed. The arc length and area of the glenoid defect were measured. Based on the arc length of the glenoid defect of the model, the size of coracoid oblique osteotomy was designed and the actual length and angle of the coracoid osteotomy were measured. A limited osteotomy suture button fixation Latarjet procedure with the coracoacromial ligament and pectoralis minor preservation was performed and the position of coracoid block was observed. ResultsAll shoulder joint specimens exhibited crossing fibers between the coracoacromial ligament and the conjoint tendon. The vertical distance from the tip of the coracoid to the coracoid return point was 24.8-32.2 mm (mean, 28.5 mm). The maximum allowable osteotomy length starting from the intersection point was 26.7-36.9 mm (mean, 32.0 mm). The maximum osteotomy angle was 58.8°-71.9° (mean, 63.5°). Based on the anteroinferior glenoid defect model, the arc length of the glenoid defect was 22.6-29.4 mm (mean, 26.0 mm); the ratio of glenoid defect was 20.8%-26.2% (mean, 23.7%). Based on the coracoid block, the length of the coracoid osteotomy was 23.5-31.4 mm (mean, 26.4 mm); the osteotomy angle was 51.3°-69.2° (mean, 57.1°). There was no significant difference between the arc length of the glenoid defect and the length of the coracoid osteotomy (P>0.05). After simulating the suture button fixation Latarjet procedure, the highest points of the coracoid block (suture loop fixation position) in all models located below the optimal center point, with the bone block concentrated in the anteroinferior glenoid defect position. ConclusionThe size of the coracoid is generally sufficient to meet the needs of repairing larger glenoid defects. The oblique osteotomy with preserving the coracoacromial ligament may potentially replace the traditional Latarjet osteotomy method.
ObjectiveTo observe the characteristics of acetabular labrum injury in Pipkin fractures and the effectiveness of repairing the labrum with suture anchor. MethodsBetween July 2010 and July 2013, 10 cases of Pipkin fractures accompanied by acetabular labrum injury were treated. There were 7 males and 3 females with an average age of 32.5 years (range, 24-56 years). The causes of injury included traffic accident in 8 cases and falling from height in 2 cases. According to the Pipkin classification criteria, there were 6 cases of type Ⅱ, 2 cases of type Ⅲ, and 2 cases of type Ⅳ. The average interval from injury to operation was 8 days (range, 6-14 days). All the patients underwent open reduction and internal fixation through transtrochanteric approach with trochanteric osteotomy, and repair the labrum with suture anchor. The effectiveness was evaluated according to the Thompson & Epstein scoring scales after operation. ResultsAll incisions healed primarily without early complication of deep infection or deep vein thrombosis of lower limb. All the cases were followed up 22 months on average (range, 12-48 months). X-ray films showed that all osteotomies and acetabular fractures healed within 3-4 months, femoral head and femoral neck fracture healed within 6-11 months. MRI examinations showed that all repaired acetabular labrums well healed. One case had necrosis of the femoral head at 12 months after operation, and was treated by total hip arthroplasty. According to the Thompson & Epstein scoring scales at last follow-up, the results were excellent in 5 cases, good in 3 cases, fair in 1 case and poor in 1 case, with an excellent and good rate of 80%. ConclusionThe diagnosis of acetabular labrum injury can be easily missed during Pipkin fracture, preoperative diagnosis should be combined with hip MRI. Trochanteric osteotomy through transtrochanteric approach, and repairing the labrum with suture anchor can restore the hip function effectively.
ObjectiveTo compare the outcomes of sutureless technique and conventional technique in the surgical repair for infracardiac total anomalous pulmonary venous connection (TAPVC).MethodsThe clinical data of 46 consecutive patients with infracardiac TAPVC undergoing surgical repair in our hospital between June 2014 and April 2019 were retrospectively analyzed. Patients with combined congenital cardiac anomalies such as single ventricle and tetralogy of Fallot were excluded. Patients were divided into a conventional technique group and a sutureless technique group according to the surgical techniques. There were 35 patients in the conventional technique group, including 28 males (80.0%) and 7 females (20.0%) with a median age of 21 (8, 42) d and a median weight of 3.6 (3.0, 4.0) kg. There were 11 patients in the sutureless technique group, including 8 males (72.7%) and 3 females (27.3%) with a median age of 14 (6, 22) d and a median weight of 3.5 (2.9, 3.6) kg. The curative effect of the two groups was compared.ResultsThere were 5 deaths (10.9%) in the conventional technique group, including 4 in-hospital deaths (8.7%) and 1 late death (2.2%). Overall mortality of the conventional technique group (14.3%, 5/35) was higher than that of the sutureless technique group (0.0%, 0/11), although the difference was not statistically significant (P=0.317). Cox regression analysis showed that sex (P=0.042), age at repair (P=0.028), cardiopulmonary bypass time (P=0.007), aortic cross-clamping time (P=0.018) and duration of ventilation (P=0.042) were risk factors for postoperative mortality. The median follow-up was 18.00 (5.00, 37.75) months. Postoperative pulmonary venous obstruction occurred in 22 patients of the conventional technique group, which was significantly more than that of the sutureless technique group (P=0.000).ConclusionFor infracardiac TAPVC, sutureless technique can reduce the incidence of postoperative pulmonary venous obstruction compared with conventional technique.
ObjectiveTo observe the clinical features and prognosis of eyes with corneal suture-related infective endophthalmitis. MethodsA retrospective interventional case series. From January 2020 to December 2021, 5 patients (5 eyes) with corneal suture-related infectious endophthalmitis diagnosed by ophthalmic examination at Department of Ophthalmology of the Eye-ENT Hospital of Fudan University were included in the study. Among them, there were 3 males and 2 females; all had unilateral disease; the mean age was 30.80±21.98 years. Sutures of 4 cases were secondary to lens related surgery and of 1 case was secondary to penetrating keratoplasty. Average retention time of corneal suture was 20.00±7.41 months. Of the 5 eyes, corneal sutures were removed in 1 eye due to redness and eye pain in another hospital; 3 eyes were loosened of the sutures in the remaining 4 eyes. The patients were given standard treatment for infectious endophthalmitis, including systemic and local anti-infective therapy; corneal suture removal, intraocular injection, and vitrectomy (PPV). In PPV, it was decided whether to give silicone oil filling according to the situation. The follow-up time after treatment was 11.00±7.38 months. The best corrected visual acuity (BCVA), B-mode ultrasound and microbial culture results of the affected eye before and after surgery were observed and analyzed.ResultsInfiltrates, ulcers, or abscesses surrounding the suture may be seen on the cornea of the affected eye. B-mode ultrasonography showed vitreous opacity, preretinal cords, and spherical wall edema in the entire segment of the affected eye. The results of vitreous humor culture were positive in 3 eyes, which were Streptococcus viridis, Staphylococcus hominis subspecies, Staphylococcus epidermidis. After treatment, all the intraocular infections in the affected eyes were successfully controlled, and there were no cases of enucleation of ocular contents or enucleation. Before treatment, the BCVA of the affected eye was from no light perception to counting fingers; after treatment, 2 eyes had BCVA＞0.3. ConclusionsInfiltration, ulcers or abscesses around the sutures can be seen in the cornea of corneal suture-related infective endophthalmitis patients, which are related to the long-term retention of the sutures in the eye. Most of the affected eyes have loose sutures when they go to the doctor; timely treatment can effectively control the infection, and some eyes have good visual prognosis.
Objective To compare the efficacy of incision healing by abdominal wall closure measure without suturing subcutaneous fat layer and the traditional abdominal wall closure measure. Methods Four hundreds patients underwent operation of abdominal median incision and abdominal paramedian incision from Sep. 2010 to Sep. 2012 in our department were randomly assigned to observation group （n=199） and control group （n=201）. The patients in obser- vation group underwent abdominal wall closure measure without suturing subcutaneous fat layer， and those of control group were subjected to abdominal wall closure by traditional layer suture technique. Comparison of efficacy of incision healing in the 2 groups was performed. Results The incidences of fat liquefication 〔1 （0.5%） vs.18 （9.0%）〕， incision swelling 〔3 （1.5%） vs.16 （8.0%）〕， incision induration 〔1 （0.5%） vs.15 （7.5%）〕， and dehiscence of wound 〔0 （0） vs.9 （4.5%）〕 in observation group were significantly lower than those of control group （P＜0.01）， but there was no significant difference in incidence of subcutaneous hematoma 〔2 （1.0%） vs.0 （0）， P＞0.05〕. The rate of primary healing in obser-vation group was significantly higher than those of control group 〔199 （100%） vs.186 （92.5%）， P＜0.01〕. Duration of abdominal closure 〔（13.0±1.6） min vs.（18.0±2.2） min〕 and postoperative hospital stay 〔（7.7±1.3） days vs.（9.6±1.9） days〕 were all shorter than those of control group （P＜0.01）. Conclusion The abdominal wall closure measure without suturing subcutaneous fat layer is obviously more effective to the traditional layer suture technique， which is a suture way worthy to spread.
