Short-term effectiveness of calcaneal lateral displacement osteotomy with lateral ligament repair in treatment of Takakura stage Ⅱ varus-type ankle arthritis / 中国修复重建外科杂志

OBJECTIVE@#To investigate the short-term effectiveness of calcaneal lateral displacement osteotomy with lateral ligament repair in the treatment of Takakura stage Ⅱ varus-type ankle arthritis.@*METHODS@#A retrospective analysis was performed on the clinical data of 13 patients with Takakura stage Ⅱ varus-type ankle arthritis treated with calcaneal lateral displacement osteotomy with lateral ligament repair between January 2016 and December 2020. There were 6 males and 7 females aged 31-65 years, with an average age of 53.6 years. The preoperative tibial-ankle surface angle (TASA) was (88.13±1.01)°, medial distal tibial angle (MDTA) was (86.36±1.49)°, tibial talar surface angle (TTSA) was (6.03±1.63)°, talar tilting angle (TTA) was (81.95±2.15)°, and tibiocalcaneal axis angle (TCAA) was (-5.74±6.81)°. The preoperative American Orthopedic Foot and Ankle Society (AOFAS) score was 56.3±7.1 and the pain visual analogue scale (VAS) score was 3.7±0.5. AOFAS scores, VAS scores, TTSA, TTA, and TCAA were compared between pre- and post-operatively.@*RESULTS@#All 13 patients were followed up 14-41 months, with an average of 28.7 months. The osteotomies healed in all patients. The last follow-up revealed TTA, TTSA, and TCAA to be (88.27±1.19)°, (-0.13±1.37)°, and (2.09±5.10)° respectively, the AOFAS score was 84.3±4.2 and the VAS score was 0.7±0.5, all showing significant improvement when compared to preoperative values ( P<0.05).@*CONCLUSION@#For patients with Takakura stage Ⅱ varus-type ankle arthritis, calcaneal lateral displacement osteotomy with lateral ligament repair can correct the lower limb force line, regain ankle stability, and achieving good short-term effectiveness.

Comparison of modified "double flaps" pyeloplasty and traditional pyeloplasty in the treatment of special types of hydronephrosis in children / 中华泌尿外科杂志

Objective:To compare the efficacy of modified "double flaps" pyeloplasty and traditional dismembered pyeloplasty in the treatment of special types of hydronephrosis with small pelvis and long proximal ureteral stricture in children.Methods:The data of 39 children with special types of hydronephrosis treated in Seventh Medical Center, General Hospital of PLA from June 2018 to June 2019 were retrospectively analyzed. Among them, 33 were boys and 6 were girls. The median age of the patients was 12.0(4.5, 63.5) months. Nine of them had left hydronephrosis and four children had right hydronephrosis. These patients with small pelvis existed the characteristics that the anteroposterior diameter of pelvis was smaller than 2.5 cm and these patients existed the symptom of hematuria, flank pain or recurrent urinary tract infection with the imaging revealing ureteral obstruction. The length of proximal ureteral stenosis ranged from 2.0 to 4.0 cm. Among 39 cases, 19 cases were operated with modified "double flaps" pyeloplasty, which was the modified "double flaps" pyeloplasty group. 20 cases were operated with traditional Anderson-Hynes pyeloplasty, which was traditional pyeloplasty group. The technique of modified "double flaps" pyeloplasty mainly included that the renal pelvis was cut into double flaps, the inferior flap was anastomosed with the spatulated ureter and the superior was covered, so that the length and caliber of the ureter were partial extended. The median age of two groups were 12.0 (6.0, 44.0) months and 12.0 (4.8, 62.8) months respectively, the anterior and posterior diameter of renal pelvis were (2.8±0.8)cm and (2.6±0.6)cm respectively, and split renal function were (36.7±5.1)% and (36.0±6.8)% respectively. There were no statistically significant differences in above parameters between the two groups( P>0.05). The clinical efficacy of the two groups were compared by collecting and comparing the operation related data and postoperative follow-up data. Results:The operation of 39 children in this study was successfully completed without conversion to open surgery.The operation time of "double flap" pyeloplasty group and traditional pyeloplasty group were (142.6±9.6) min and (124.5±8.6) min respectively, and the intraoperative anastomosis time were (56.1±7.2) min and (47.6±4.8) min respectively. There were significant difference in operation time and intraoperative anastomosis time between the two groups( P<0.05). Thirty-nine children were followed up normally without loss. The mean follow-up time was (27.7±2.5) months after surgery. In the "double flaps" pyeloplasty group, 2 cases suffered with fever who were diagnosed as urinary tract infection and improved after antibiotic treatment. In the traditional pyeloplasty group, 2 cases suffered with fever who were diagnosed as urinary tract infection and improved after antibiotic treatment. Two children had flank pain during follow-up to more than one year and the examination revealed that the anteroposterior diameter of the renal pelvis gradually increased. So surgery were performed again and the two children recovered. There were no significant differences in complication rate (2/19 and 4/20) and short-term surgical success rate(19/19 and 18/20) between the two groups ( P>0.05). Conclusions:The operation time and anastomosis time of the modified "double flap" technique for treating hydronephrosis are longer than those of the traditional method. But in the treatment of special types of hydronephrosis with small renal pelvis or long proximal ureteral stricture, it may have application prospects in reducing complications.

Clinical evaluation of Compound Chamomile and Lidocaine Hydrochloride Gel for postoperative hypospadias in children / 中华男科学杂志

Objective@#To evaluate the clinical efficacy of Compound Chamomile and Lidocaine Hydrochloride Gel for postoperative hypospadias in children.@*METHODS@#From January to December 2020, we treated 116 children with distal hypospadias in the Department of Urology, Department of Pediatrics and the Seventh Medical Center of the PLA General Hospital, 58 by primary Snodgrass urethroplasty only (the control group) and the other 58 with Compound Chamomile and Lidocaine Hydrochloride Gel smeared on the penis postoperatively in addition (the trial group). We compared the operation time and postoperative pain score, edema regression and incidence of infection between the two groups, followed by statistical analysis using T test and Chi-square test.@*RESULTS@#All the operations were successfully completed by the same surgeon under general anesthesia. There were no statistically significant differences between the trial and control groups in age (［2.5 ± 0.8］ vs ［2.4 ± 0.6］ yr, P > 0.05) or operation time (［95.6 ± 14.5］ vs ［97.1 ± 15.2］ min, P > 0.05). No incision infection occurred in any of the cases. The pain scores at dressing removal were remarkably lower in the trial than in the control group at 2 hours (1.4 ± 1.0 vs 2.6 ± 1.3, P < 0.05), 24 hours (2.2 ± 1.3 vs 3.9 ± 1.6, P < 0.05), 48 hours (1.2 ± 0.7 vs 1.6 ± 0.9, P < 0.05) and 72 hours after surgery (2.5 ± 0.8 vs 3.7 ± 1.8, P < 0.05). Significantly more cases of edema regression were achieved in the trial than in the control group at 2 weeks postoperatively (35 vs 19, P < 0.05).@*CONCLUSIONS@#Compound Chamomile and Lidocaine Hydrochloride Gel can effectively relieve pain, reduce edema and accelerate edema regression after surgery in children with hypospadias, and therefore deserves wide clinical application.、.

Comparison of ArcCheck and film verification for VMAT in the treatment of nasopharyngeal carcinoma / 中国医疗器械杂志

To compare the performance of ArcCheck and film verification for volumetric intensity modulated arc therapy (VMAT) in the treatment of nasopharyngeal carcinoma, and to study the feasibility of ArcCheck in VMAT dosimetric verification. Five patients of nasopharyngeal carcinoma treated with VMAT were enrolled in this study. Dose verification was carried out by ArcCheck and film respectively. The result showed that there were no significant differences between ArcCheck and film verification. ArcCheck software can obtain three dimensional dose distribution directly with simple operation. It is convenient for ArcCheck to be used for VMAT dosimetric verification.
