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.
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.
ObjectiveTo evaluate the effectiveness of arthroscopic suture and absorbable screw double fixation for both anterior and posterior cruciate ligament avulsion fractures of tibial insertions. MethodsBetween June 2006 and September 2013, 8 patients with anterior and posterior cruciate ligament avulsion fractures of the tibial eminence underwent arthroscopic treatment with suture and absorbable screw double fixation. There were 5 males and 3 females, with a mean age of 28.9 years (range, 18-43 years). The causes of injury included traffic accident in 5 cases and falling from height in 3 cases. The time from injury to operation was 3-10 days (mean, 6.2 days). The Lysholm knee score, International Knee Documentation Committee (IKDC) score, and Tegner rating scales were used to evaluated the knee function. ResultsPrimary healing of incision was obtained, without infection or deep vein thrombosis. The mean follow-up period was 42.4 months (range, 24 to 65 months). At 3 months after operation, X-ray films showed good reduction and healing of fracture. The anterior and posterior drawer tests were negative. The knee range of motion was normal (0-125°), and it recovered to preoperative level in 7 cases. The IKDC score, Tegner score, and Lysholm score were significantly improved to 90.4±5.2, 7.5±1.6, and 89.2±3.5 from preoperative 52.1±3.3, 3.3±1.0, and 51.9±3.5 respectively (t=-38.680, P=0.000; t=-39.520, P=0.000; t=-41.150, P=0.000). ConclusionA combined injury of anterior and posterior cruciate ligament avulsion fractures of tibial insertions is rare. Arthroscopic treatment with suture and absorbable screw double fixation is a useful technique to restore tibial avulsion injuries with well-documented radiographic healing, good clinical outcomes, and low complication rates.
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 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.
ObjectiveTo evaluate the feasibil ity and effectiveness of suture ligation combined with super-wet tumescent technique to replace embolization before surgical resection of peri pheral arteriovenous malformations (AVMs) of the head and neck. MethodsBetween July 2007 and November 2010, 9 patients with peri pheral AVMs of the head and neck were treated, including 4 males and 5 females with a median age of 21 years (range, 8 months to 55 years). The causes were congenital malformation in 6 cases, trauma in 2 cases, and unknown origin in 1 case. The lesions were located at the frontotemporal region in 2 patients, cheek in 2 patients, occi pitocervical region in 2 patients, temporoparietal region in 1 patient, upper lip in 1 patient, and lower lip in 1 patient. The size of the AVMs lesions ranged from 2.2 cm×1.2 cm to 13.0 cm×10.0 cm. Of 9 cases, 8 were classified as Schobinger gradeⅡand 1 as gradeⅢ. The AVMs involved 2 to 7 main nutrient arteries, with a diameter range of 1.7-3.1 mm. At one-stage operation, AVMs was removed and direct suture, skin graft or flaps were used for repair in 6 cases; the skin was expanded at one-stage operation, and then AVMs removal and repair were performed at twostage operation in 3 cases. Before resection of AVMs, No.7 silk suture was used to l igate the main nutrient vessels, and then annular interrupted suture of soft tissue was performed with the silk sutures around the lesions, at least two rings. Tumescent anesthetic solution was injected into lesions, and super wet end-point achieved. ResultsPartial incision dehiscence occurred in 1 patient; the flaps and grafting skin survived, and primary healing of incision was obtained in the other patients. The mean operation time was 136 minutes (range, 42-367 minutes). The mean intraoperative blood loss was 268 mL (range, 15-1 000 mL). Only 1 patient received 3 units of blood transfusion. All patients were followed up for 4.2 years on average (range, 2 years to 6 years and 6 months); there was no recurrence case. The self-assessment cosmetic results were excellent or good in 5 cases and fair in 4 cases. ConclusionIntensive suture ligation followed by super-wet tumescent techniques might partially substitute preoperative embolization to facil itate surgical resection of peri pheral AVMs of the head and neck, due to simple operation and less bleeding.
ObjectiveTo evaluate and compare the effectiveness of double Endobutton technique and suture anchor combined Endobutton plate in the treatment of Tossy type Ⅲ acromioclavicular joint dislocation. MethodsBetween May 2010 and March 2014, a retrospective study was preformed on 56 patients with Tossy type Ⅲ acromioclavicular joint dislocation. The coracoclavicular ligament was reconstructed with double Endobutton technique in 31 cases (Endobutton group), and with suture anchor combined Endobutton plate in 25 cases (Anchor group). There was no significant difference in age, gender, injury causes, injury side, associated injury, medical comorbidities, and disease duration between 2 groups (P>0.05). The operation time, medical device expenses, postoperative complications, preoperative and postoperative Constant-Murley scores, and postoperative Karlsson grading of the injured shoulder were compared between 2 groups. ResultsThe average operation time in Endobutton group was significantly greater than that in Anchor group (t=4.285, P=0.000); there was no significant difference in the medical device expenses between 2 groups (t=1.555, P=0.126). Primary healing of incision was obtained in all patients of 2 groups; no early complications of infection and skin necrosis occurred. All patients were followed up 15.6 months on average (range, 11-35 months). During follow-up, some loss of reduction and ectopic ossification in the coracoclavicular gap were observed in 1 case and 6 cases of Endobutton group, respectively. No recurrence of acromioclavicular joint dislocation, implant fixation loosening and broken, and secondary fractures occurred in the other patients. There was significant difference in the incidence of postoperative complications between 2 groups (P=0.013). Constant-Murley scores of the injured shoulder significantly increased at 9 months after operation when compared with preoperative values in 2 groups (P<0.05), but no significant difference was observed between 2 groups (P>0.05). At last follow-up, there was no significant difference in Karlsson grading between 2 groups (Z=-0.628, P=0.530). ConclusionBoth double Endobutton technique and suture anchor combined Endobutton plate have good effectiveness in the treatment of Tossy type Ⅲ acromioclavicular joint dislocation. But the latter is associated with easier operation, less operation time, and less complications.
Objective To investigate the clinical efficacy between suture button plate and cortical screw in the treatment of distal tibiofibular syndesmosis seperation. Methods The clinical data and follow-up data 1 week and 2, 4, 6 weeks and 3, 6, 12 months after operation of patients with distal tibiofibular syndesmosis seperation combined with or without ankle fracture who were admitted to hospital from March 2011 to May 2014 were retrospectively collected. According to the fixation ways of distal tibiofibular syndesmosis, the patients were divided into the suture button plate group and the cortical screw group. The operation time, amount of blood loss, combined ankle fracture healing time, American Orthopaedic Foot and Ankle Society (AOFAS) scores at the last follow-up and complications were compared between the two groups. Results A total of 52 patients were enrolled, including 28 cases of suture button plate group and 24 cases of cortical screw group. There were no significant difference in operation time or amount of blood loss between the two groups (P>0.05). All patients were followed up for 12–30 months averaged 14.5 months. All incisions healed by the first intention. The combined ankle fracture healing time in the suture button plate group was (11.2±2.0) weeks, while that was (11.0±2.1) weeks in the cortical screw group, with no significant difference between the two groups (P>0.05). In the suture button plate group, there was no loosening or rupture of internal fixation, while distal tibiofibular syndesmosis seperation was found again in one case 3 weeks after operation, and cured by reoperation at last. In the cortical screw group, rupture of screws was found in 2 cases, which occurred 9 and 11 weeks after operation respectively, and the broken screws were taken out when the fractures were healed and the internal fixation was removed; distal fibiofibular syndesmosis seperation was found again in one case 6 weeks after operation, and no treatment was given due to old age and low demand. At the last follow-up, the AOFAS score in the suture button plate group was 84.6±10.2, while the score in the cortical screw group was 83.7±12.5, with no significant difference between the two groups (P>0.05). Conclusions Suture button plate and cortical screw can effectively treat distal fibiofibular syndesmosis separation. The risk of suture button plate loosening or rupture is poor. Suture button plate fixation can meet the need of early functional exercises, and avoid the routine removal by reoperation.
OBJECTIVE To investigate the effect of meniscus suture on meniscus healing which included healing time and healing pattern. METHODS Fourty healthy rabbits were adopted in this study. The model of meniscus injury was made by a longitudinal incision at the medial meniscus of the left knee. The rabbits were divided into two groups, the experimental group was treated by meniscus suture and the control group was unsutured. After operation, the meniscus samples were collected periodically and observed by gross, light and electronic microscope to analysis the meniscus healing. RESULTS The injured meniscus was healed gradually and completely at the sixth week in the experimental groups. More fibroblasts and less fibrocartilage cells could be observed in the healed meniscus. Oppositely, there was no meniscus healing in the control group and the edge of injured meniscus was sealed by epithelioid cells. CONCLUSION The meniscus suture can accelerate the healing process of meniscus injury. Besides, early suture make the injured meniscus correctly positioned to ensure the normal healing process.
