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.
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.
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.
ObjectivesTo systematically review the efficacy of absorbable barbed suture versus traditional absorbable suture in total knee arthroplasty (TKA).MethodsPubMed, EMbase, The Cochrane Library, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect clinical trials of absorbable barbed suture versus traditional absorbable suture in TKA from inception to November, 2017. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 6 randomized controlled trials (RCTs) and 5 cohort studies were included, involving 2 008 patients. Meta-analysis showed that the joint capsule suture time of the absorbable barbed suture group [MD=–4.31, 95% CI (–4.72, –3.90), P<0.000 01], the incidence of acupuncture injury during suture [OR=0.14, 95% CI (0.03, 0.61),P=0.009], and incision complication rate [OR=0.56, 95% CI (0.36, 0.88), P=0.01] were significantly lower than the traditional absorbable suture group, but the incidence of suture fracture [OR=23.03, 95% CI (3.08, 172.09),P=0.002] was higher, yet the difference was statistically significant. There were no significant differences in the incidence of superficial infection, deep infection, aseptic redness, incision dehiscence and KSS score at 3 months after operation (P>0.05).ConclusionsAvailable evidence suggests that the use of absorbable barbed sutures to close the TKA surgical incision shortens the time to suture the joint capsule, reduces the incidence of acupuncture injury as well as the overall incidence of incision complications without increasing superficial infection, deep infection, and sterility. The incidence of redness and incision splitting has no significant effects on joint function at 3 months after surgery, however the incidence of suture fracture is higher. Due to limited quality and quantity of the included studies, the above conclusions are required to be verified by more high-quality studies.
Objective To investigate the methods and effectiveness of surgical treatment for posteromedial corner (PMC) injury combined with anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) ruptures. Methods Between February 2009 and February 2012, 15 patients (15 knees) with PMC injury combined with ACL and PCL ruptures underwent PMC repair with suture anchor and ACL and PCL reconstruction. There were 7 males and 8 females with an average age of 39 years (range, 15-59 years). The causes of injury were traffic accident injury in 6 cases, sport injury in 7 cases, and sprain injury in 2 cases. The disease duration was 3-15 days with an average of 7 days. All patients presented positive results of anterior drawer test, posterior drawer test and valgus stress test, and dysfunction of knee joint. Of 15 cases, 3 had ACL and PCL ruptures, 5 had ACL rupture, 3 had ACL injury at the attachment point of the condyles crest, and 4 had PCL rupture; 9 had PMC tear at the femur insertion, 5 had PMC tear at the tibia insertion, and 1 had PMC tear in the body area. Results All incisions healed by first intention with no complication of infection or stiffness of knee. All cases were followed up 18.4 months on average (range, 10-36 months). At last follow-up, 14 cases had normal knee flexion and extension ranges, but 1 case had 10° limitation of the knee extension. Except 1 case which had weakly positive valgus stress test, the other patients showed negative results of anterior drawer test, posterior drawer test, and valgus stress test. Based on the improved Lysholm classification standard, the results were excellent in 8 cases, good in 5 cases, and fair in 2 cases; the excellent and good rate was 86.7%. Conclusion Early repair of the PMC and reasonable reconstruction of cruciate ligament can effectively restore the knee stability for patients with PMC injury combined with ACL and PCL ruptures.
ObjectiveTo introduce a modified sutureless technique and its surgical results in the treatment of total anomalous pulmonary venous connection (TAPVC).MethodsClinical data of 11 patients with TAPVC who underwent the modified sutureless technique treatment from 2014 to 2019 in our center were retrospectively analyzed, including 4 males and 7 females. The median surgical age was 1.4 (0.3, 27.0) months. The median weight was 4.3 (3.5, 8.5) kg.Six (54.5%) patients were of supracardiac subtype, and five (45.5%) patients were of infracardiac subtype. Five (45.5%) patients had preoperative severe pulmonary hypertension, and three (27.3%) patients had preoperative pulmonary vein obstruction. The surgical results were compared with those of 10 patients treated with conventional surgical technique.ResultsThe median follow-up was 12 (range, 1-65) months. During the follow-up, no death or postoperative pulmonary vein obstruction occurred in the modified sutureless technique group. The perioperative data and relief of re-obstruction were superior in the modified sutureless technique group, but the difference was not statistically significant (P>0.05). The postoperative survival of the the modified sutureless technique group was better than that of the traditional surgery group (P=0.049).ConclusionThe modified sutureless technique which includes partial suture and then incising, and eversion of pulmonary vein incision, is a safe and reliable method for the treatment of TAPVC with satisfactory short-term results.
ObjectiveTo investigate the effectiveness of a suture bridge technique for quadriceps tendon rupture repair in uraemic patients. MethodsBetween March 2010 and September 2012, 10 uraemic patients (14 sides) with quadriceps tendon rupture were treated with the suture bridge technique. Of them, 8 were male and 2 were female, aged from 30 to 62 years (mean, 54.2 years). The duration of uremia was 3-11 years (mean, 5.5 years);the duration of quadriceps tendon rupture was 5 days to 2 months (median, 12 days). Six cases had a trauma history, and one case had diabetes. The left side was involved in 2 cases, the right side in 4 cases, and both sides in 4 cases. The active range of motion (ROM) of the knees was (115.0±8.3)°in flexion, and (72.5±21.2)°in extension. Lysholm score was 19.5±16.3. X-ray films showed downward shifting of patella. MRI revealed discontinuity between distal quadriceps tendon and upper pole of patella. ResultsThe operation time was 30-50 minutes (mean, 40.3 minutes). Primary healing of incision was obtained in all patients without complications. All patients were followed up 12-25 months (mean, 16.3 months). There was no re-rupture of quadriceps tendon or loosening of internal fixation during follow-up. At last follow-up, the active ROM of the knees was (121.0±7.9)°in flexion, showing no significant difference when compared with preoperative one (t=-2.075, P=0.058); the active ROM was (8.2±6.1)°in extension, showing significant difference when compared with preoperative one (t=11.702, P=0.000). Lysholm score was 84.6±12.4, showing significant difference when compared with preoperative score (t=-16.226, P=0.000). According to the American Knee Society score (KSS), the results were excellent in 4 sides, good in 9 sides, and fair in 1 side, and the total excellent and good rate was 92.9%. At last follow-up, the active ROM of the knee, Lysholm score, and KSS score were significantly better in young patients (<45 years) than in elder patients (≥45 years), and in patients receiving early operation (<2 weeks) than in patients receiving late operation (≥2 weeks) (P<0.05). ConclusionFor fewer traumas and early functional exercise after operation, the suture bridge technique benefits functional restoration of knee joint in uraemic patients. Operation chance and age seem to be important factors to the results. Early operation should be considered when quadriceps tendon ruptured.
Objective To analyze the short-term effectiveness of repairing musculus extensor carpi radialis brevis (ECRB) and extensor digitorum communis (EDC) tendon using suture anchor after debridement of extensor tendon insertion for recalcitrant lateral epicondylitis. Methods Between March 2009 and May 2011, 10 patients (10 elbows) with recalcitrant lateral epicondylitis received repair of the ECRB and EDC tendon to the lateral epicondyle using a single suture anchor after debridement of extensor tendon insertion. There were 6 males and 4 females with an average age of 45.4 years (range, 36-57 years). The dominant elbow was involved in 8 patients and nondominant elbow in 2 patients; there were 4 manual workers and 6 ordinary workers. The disease duration ranged from 8 to 24 months (mean, 12.3 months). All patients had epicondylus lateralis humeri pain, local swelling and tenderness, and positive Mill sign. The average elbow range of motion (ROM) was 11.3°(range, 0-30°) in extension and was 132.5°(range, 120-145°) in flexion. Preoperative MRI showed external humeral epicondylitis in all patients. ResultsPrimary wound healing was obtained in all patients without complications of infection, leakage of joint fluid, and stiffness of elbow. Ten patients were followed up 4 to 23 months with an average of 12 months (more than 12 months in 7 cases). The time to return to work was (3.75 ± 0.95) months for manual workers and was (2.91 ± 0.20) months for ordinary workers, showing no significant difference (t=1.715, P=0.180). Compared with preoperation, the mean visual analogue scale (VAS) score significantly decreased (P lt; 0.05), and Mayo score and the grip strength of dominant and nondominant significantly increased (P lt; 0.05), but no significant difference was found when compared with non-surgical side at last follow-up (P gt; 0.05). At last follow-up, the average ROM was —1.5° (range, 0-—10°) in extension and was 150.5°(range, 140-160°) in flexion. ConclusionTo suture anchor for repairing the ECRB and EDC after debridement is a satisfactory procedure to treat recalcitrant lateral epicondylitis. It can effectively prevent loss of the forearm extensor strength, relieve the pain, recover the grip strength, and obtain good results.
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.
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.
