One-stage repair of ankle fracture combined with grade Ⅲ injury to lateral ligament / 中华创伤骨科杂志

Objective To investigate the surgical outcomes of one-stage repair of the ankle fracture combined with grade Ⅲ injury to the lateral ligament.Methods From April 2015 to December 2017,23 patients with ankle fracture and lateral ligament injury were treated at Department of Traumatic Reconstruction Surgery/Foot and Ankle Surgery,Zhongnan Hospital.There were 15 males and 8 females,aged from 18 to 65 years (average,37.8 years).After intraoperative treatment of their fractures,22 ruptures of the ligamentous insertion were repaired with suture anchor and one rupture of the middle ligament with Internal Brace.Routine postoperative X-rays,physical examination and Sefton grading system were used to evaluate the stability of the ankle joint and the subtalar joint.The Karlsson-Peterson and American Orthopedic Foot and Ankle Society (AOFAS) scores were used to evaluate the function and pain of the ankle.Results The follow-up for this cohort ranged from 12 to 24 months (average,13.9 months).The bone union time ranged from 6 to 24 weeks,averaging 10.1 weeks.There was no chronic instability of lateral ankle or subtalar joint in all the cases.Two cases developed osteochondral lesion of the medial talus which was treated with micro-fracture surgery one year after injury;one case suffered subtalar arthritis which was treated by subtalar arthrodesis 14 months after injury.Their Karlsson-Peterson scores averaged 84.6 points and AOFAS ankle-hindfoot scores 93.7 points with 19 excellent and 4 good cases.The Sefton grading system gave 9 cases of grade Ⅰ and 14 ones of grade Ⅱ.Conclusion One-stage repair of the ankle fracture combined with grade Ⅲ injury to the lateral ligament can lead to the stability of the ankle joint and the subtalar joint and improved function of the ankle.

One-stage surgical repairs for interrupted aortic arch associated with cardiac defects in infants / 中华胸心血管外科杂志

Objective To sum up the clinical information and outcomes of one-stage surgical repairs for interrupted aortic arch (IAA) associated with cardiac defects through median stemotomy in infant.Methods From August 2005 to January 2012,23 IAA patients,aged 18 days to 3 years [mean age (8.61 ± 11.81) months],body weight 3.3-13.0 kg [mean (6.61 ± 3.26) kg] were reviewed underwent one-stage repair.There were 12 male and 11 female.The anatomic subtype ineluded type A 20 (87.0％),type B 3 (13.0％),and no type C in the records.All cases included ventricular septal defect and patent ductus artefious,some also with artirical-pulmonary window,aterical septal defect,bicuspid or unicuspid aortic valve,and subvalvular aortic stenosis.Diagnosis was determined in of the patients and suspected in by echocardiography.Also,64 layers helico-CT was employed to make a definite diagnosis for 18 patients and cardiac catheterization was used for 4 patients.All patients with cardiac anomalies underwent one-stage repair through median sternotomy.The aortic continuity was reestablished by anastomosis between the descending aortic segment and aortic arch.Results In all 23 cases,21 were successful.There was 2 (8.69％) postoperative death:one was due to surgical hemorrhage and severe low cardiac output during perioperative stage and the other was 2-month old due to crisis of pulmonary hypertension.CPB time was ranged from 53-215 min [(129.76 ± 38.98) min],and aortic crossclamp time was 34-125 min[(74.47 ± 24.30) min].The length of stay in ICU postoperatively was 96h averagely.The postoperative complications included severe low cardiac output syndrome in 3 patients,hypoxemia in 13,pneumonia in 7,and supraventricular tachycardia in 12.21 patients were followed up from 2 months to 6 years and were in good condition without recoactation.Conclusion The outcomes of early and medium term for one-stage repair of IAA and associated cardiac anomalies through median stemotomy is excellent.Technique of extended anastomosis between the descending aortic segment and aortic arch may reduce the incidence of recoarctation.It is simplified the procedure and improved life quality of patients.

Application of magnetic compression anastomosis in one-stage repair of the intestinal leakage / 中华消化外科杂志

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P ＜ 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P ＞ 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.

Surgical Outcome of Proximal Hypospadias with Penoscrotal Transposition / 대한비뇨기과학회지

PURPOSE: Penoscrotal transposition is found in cases with severe form of hypospadias. In those cases, severe chordee generally coexists and a long length of urethra may be necessary for its correction. We evaluated the clinical outcome of surgical repairs for 12 patients of proximal hypospadias with penoscrotal transposition. MATERIALS AND METHODS: Out of 12 cases, there were 2 with penoscrotal type, 7 with scrotal type and 3 with perineal type hypospadias. All cases had moderate to severe chordee. Five cases were treated with one-stage repair and seven cases with multi-stage repair. We analysed operative methods, postoperative complications and those managements between the cases of one-stage and multi-stage repairs. RESULTS: For one-stage repair, we used transverse preputial island flap method in 3 cases and urethroplasty using scrotal skin flap in 2 cases. For multi-stage repair, we performed Thiersh-Duplay urethroplasty in 2 cases, bladder mucosal graft in 2 cases and Belt-Fugua urethroplasty in 3 cases. Correction of penoscrotal transposition was performed successfully in all cases. In all cases, a paucity of skin was the most difficult problem. The overall complication rate was 50.0%. In cases treated with one-stage repair, there were two cases with urethrocutaneous fistulas. However, in cases treated with multi-stage repair, there were four cases with complications such as urethral strictures, urethrocutaneous fistulas with or without large skin defect. Overall the complications in cases with multi-stage repair were more severe than those in cases with one-stage repair. CONCLUSIONS: Our experience suggests that multi-stage operation may be not superior to one-stage operation in cases with proximal hypospadias associated with penoscrotal transposition. Thus we recommand one-stage repair in those cases despite a paucity of foreskin.
