Objective To investigate the clinical effect of retroperitoneal laparoscopic dismembered pyeloplasty on ureteropelvic junction obstruction (UPJO). Methods From November 2010 to September 2015, a total of 28 cases (21 males and 7 females) with ureteropelvic junction obstruction (UPJO) underwent retroperitoneal laparoscopic dismembered pyeloplasty. All the 28 patients had a previous history of different degrees of lumbar pain, which was confirmed as typical UPJO by imaging examination. Operation method: following complete renal pelvis and upper ureter isolation, the renal pelvis was clipped into a trumpet-shaped mouth, 1/3 of the upper renal pelvis was temporarily kept without section. In the inferior margin of renal pelvis, longitudinal cut procedure was operated in the ureter and across the stenotic segment in about 1–2 cm; and then, anastomosis of the ureter and the renal pelvis at the lowest was performed, to maintain the continuity of the renal pelvis and ureter. Subsequently, the stenosed segment of ureter and the dilatant renal pelvis were removed, the posterior ureteropelvic anastomosis was made with an interrupted suture, and antegrade stenting of double J tube was further performed, followed by a continuous suture of the anterior wall. Results The procedure was successfully accomplished in all patients whithout conversion to open surgery. The operating time was 90-240 minutes with the median time of 160 minutes. The estimated blood loss was 20-70 mL with the median of 50 mL. No severe surgical complication occurred in perioperative period. The 3-24 -month follow up showed that symptoms of lumbar pain were relieved or disappeared in all the incorporated patients. Postoperative radiographic examination showed no stomal stenosis at the ureteropelvic junction, and the hydronephrosis was alleviated. Conclusions Retroperitoneal laparoscopic dismembered pyeloplasty for UPJO is an effective, safe, and minimally invasive surgical technique. The key to the success of the operation is to the accurate renal pelvis clipping, tension- and torsion-free anastomosis of the lowest position of the renal pelvis and the ureter, and the reconstruction of a new funnel-shaped ureteropelvic junction.
ObjectiveTo explore the clinical efficacy and safety of ligation of intersphincteric fistula tract in the treatment of high simple anal fistula.MethodsA prospective collection of 72 patients diagnosed with high simple anal fistula, who admitted to the department of the author’s hospital between March 2015 and December 2017 was performed, and then the patients were divided into two groups according to the random number table method combined with the patients’ wishes: the ligation of intersphincteric fistula tract group (experimental group, 32 cases) and the low incision and high hanging group (control group, 40 cases). Comparison of indexes on the operative effect and physiological function of the sphincter in six months after operation was performed.ResultsCompared with the control group, the patients in the experimental group had short postoperative pain duration, short postoperative wound healing time, high cure rate, low recurrence rate, low initial sensory threshold, high anal resting pressure, and long anal high pressure band length, with statistically significant differences (P<0.05). However, there was no statistically significant difference between the two groups in the operation time, anal maximal contractive pressure, and rectal resting pressure (P>0.05). The results suggested that the physiological function of anus in the experimental group recovered well.ConclusionThe ligation of intersphincteric fistula tract is a safe and reliable method in the treatment of high simple anal fistula, which can be widely used in the clinic.

Conclusion CD-RAP test provides a new way to study repair of cartilage and metastsais of melanoma.
The strategies of individualized enhanced recovery after surgery (ERAS) are particularly important in the anesthesia management of same-day surgery. This review focuses on the perioperative management of day surgeries following the experiences of Day Surgery Center, West China Hospital, Sichuan University and different surgeries’ guidelines of ERAS, including anesthesia evaluation, preoperative education and optimization, comorbidity management, airway management, choice of technologies and drugs during anesthesia, intraoperative monitor and anesthesia management, postoperative analgesia, postoperative nausea and vomiting prevention, and postoperative management, which is significant to ensure the discharge of the patient in time for same-day surgeries.
Abstract: Objective To evaluate the results of surgical treatment of tetralogy of Fallot in adults． Methods From July 2002 to August 2009，75 adult patients with tetralogy of Fallot received surgical treatment in Xijing Hospital, ForthMilitary Medical University．There were 35 males and 40 females, with age at l7 to 37 years (23.30±3.50 years), and eoperativehemoglobin at 143 to 231 g/L(172.00±31.00 g/L)．All these patients were diagnosed by.echocardiograph before operation. All the patients were received tetralogy of Fallot of corrective operation in the hypothermia cardiopulmonary bypass. A total of 46 patients had a transannular right ventricular outflow tract patch，and 29 patients had a non ansannular patch． Results Operation time was 157 to 276 min(221.32±41.34 min), cardiopulmonary bypass time was 68 to 163 min(91.71±28.35 min) and aorta intercepted time was 37 to 96 min（55.47±23.61 min）. There were 6 operative deaths with an operative mortality at 8.00％. The causes of death were low output syndrome(n=3)，acute renal failure(n=2)， and multiple organ failure(n=1)．Nine patients needed reoperation for postoperative bleeding(12.00％)．We followed up 69 patients from 3 to 56 months (26.31±7.40 months). There were 2 patients with trivial residual shunt. The cardiac function status were New York Heart Association(NYHA) Ⅰ to Ⅱ in the 69 patients．No late death occured． Conclusion The effectiveness of surgical treatment for adults with tetralogy of Fallot is satisfactory．
Objective To observe the incidence rate of cardiovascular adverse events and evaluate the safety of dexmedetomidine or midazolan sedation in patients with long-term mechanical ventilation in intensive care unit (ICU). Methods From January 2014 to December 2015, patients admitted to ICU aged ≥18 years with mechanical ventilation time ≥48 hours were randomly divided into dexmetomidine group (group D) and midazolam group (group M). Adverse events such as cardiovascular events during sedation were observed. Results There were 144 cases in group D and 143 cases in group M. Slow heart rate was the prominent manifestation in group D. The incidence of heart rate <50 beats per minute in group D (4.86%) was less than that in group M (6.29%), but there was no statistical difference ( P=0.681). Group D had lower blood pressure (40.28% vs. 72.73%), tachycardia (18.75% vs. 41.96%), arrhythmia (16.67% vs. 34.97%) and 28- day mortality (22.22% vs. 42.66%) than those in group M (P<0.01). No cardiac arrest, sinus arrest, hypertension, hyperglycemia, or hypoglycemia were found in the two groups. Conclusion The long-term sedation of dexmetidine in patients with mechanical ventilation is safe; in cardiovascular adverse events, the 28-day mortality is lower than that of traditional midazolam sedation, and the duration of mechanical ventilation is no longer than that of traditional midazolam sedation, with slightly longer ICU length of stay.
ObjectiveTo investigate the effectiveness of partial anterior cruciate ligament (ACL) suture repair with wide awake local anesthesia no tourniquet (WALANT) technique.MethodsBetween July 2017 and July 2019, 18 patients with partial ACL injury were admitted. There were 10 males and 8 females, with an average age of 40.5 years (range, 22-57 years). There were 5 cases on the left knee and 13 cases on the right knee. Forteen cases had a clear history of trauma or sports injury, and 4 cases had no obvious cause. The time from injury to operation was 1-6 months (median, 3 months). Partial ligament was sutured using WALANT technique under arthroscopy. The operation time, total hospital stay, and postoperative hospital stay were recorded. Lachman test and anterior drawer test were performed to evaluate the knee joint stability after treatment, and Lysholm and International Knee Documentation Committee (IKDC) scores were used to evaluate the knee function. Five-point Likert scaling were used to evaluate postoperative patient satisfaction.ResultsThe operation time was 30-100 minutes (mean, 64.2 minutes). The total hospital stay was 2-12 days (mean, 4.5 days). Postoperative hospital stay was 1-4 days (mean, 1.8 days). All incisions healed by first intention after operation, and no surgery-related complications occurred. All patients were followed up 12-36 months (mean, 19.1 months). Lachman test and anterior drawer test were negative after operation. Lysholm score and IKDC score at 6 and 12 months after operation were significantly higher than those before operation, and at 12 months after operation were higher than those at 6 months after operation, the differences were significant (P<0.05). At last follow-up, according to five-point Likert scaling of patient satisfaction, 7 cases were very satisfied, 10 cases were relatively satisfied, and 1 case was general. The total patient satisfaction rate was 94.4% (17/18). MRI scan showed the good ligament tension.ConclusionUsing WALANT technique to repair partial ACL injuries under arthroscopy can retain the patient’s own ligament tissue to the maximum extent and achieve satisfactory short-term effectiveness.

Methods A retrospective study was made on the result of clinical data and longterm followup of 259 patients who had undergone the Chinesemade C-L pugesturt tilting disc mechanical valve replacement from October 1991 to November 2006. Results The data showed that there were 12 patients died in the duration of hospital stay.The hospital mortality was 4.63% (12/259).There were no mechanical valverelated complication in the earlier postoperative period.The mortality fell to 2.59% since 1996.Among the 235 patients,12 patients were lost during the followup,the rate of followup was 95.1%(235/247).The time for followup was 9.77±3.09 years. There were 26 late deaths.During the follow-up,death associated with the deterioration of valve structure were not observed. The 5 years, 10 years and l5 years survival rates were 86.80%±2.30%, 78.20%±3.33% and 55.23%±4.34% respectively; the thromboembolic event free rates for 5 years, 10 years and l5 years were 95.95%±0.74%, 92.52%±4.11% and 80.52%±4.11% respectively; the anticoagulant related bleeding free rates for 5 years, 10 years and l5 years were 94.64%±1.75%, 89.55%±3.28% and 79.39%±4.43% respectively.There were 141 patients(67.46%) in New York Heart Association(NYHA) classⅠ, 56 patients(26.79%) in class Ⅱ, 10 patients(4.78%) in class Ⅲ and 2 patients(0.95%) in class Ⅳ. Conclusion The results of follow-up for 15 years suggest that the Chinesemade C-L pugesturt tilting disc medical mechanical valve is a reliable and safe choice for mitral valve replacement.
Objective To explore the reoperative techniques of differentiated thyroid carcinoma. Methods Clinical data of 56 patients who treated in The First Affiliated Hospital of General Hospital of PLA and General Hospital of PLA from Feb. 2011 to Feb. 2013 were analyzed retrospectively. Results All performed surgeries were successful. Surgeries took 90-150 minutes with an average of 120 minutes. Bleeding during surgeries was 70-200 mL with an average of 120 mL. Postoperative drainage was 90-210 mL with an average of 100 mL. The pathological diagnosis of the second surgery in 44 cases were as the same as the first， but there were no malignant tumor tissues of dissected glands in 12 cases. All patients had no postoperative bleeding and bucking， but 8 patients experienced hand and foot numbness， and 5 patientsexperienced transient hoarseness. Fifty patients were followed-up for 6-30 months （average 10.8 months） from the reoper-taion and 18-66 months （average 45.2 months） from the first operation， and rate of postoperative followed-up was 89.3%（50/56）. During the followed-up， 1 patient with papillary thyroid carcinoma and 1 patient with follicular thyroid carcinoma died in 44 months and 38 months respectively， 3 patients suffered lymph node metastasis at non-Ⅵ region ofaffected side， no one suffered recurrence. Conclusions For differentiated thyroid carcinoma patients who are undergoingthe second surgery， thorough whole body condition analysis should be performed and appropriate type of surgery should be chosen. By using recurrent laryngeal nerve monitoring， carbon nanoparticles for lymph node clearance， and protecting parathyroid gland to lower the possibility of postoperative complication， to improve survival rate and life quality.
ObjectiveTo compare the ascending aortic diameter and postoperative outcomes of patients with simple ascending aortic dissection or simple ascending aortic dilatation and to study the reliability of the surgical indication in present guideline for Chinese patients with ascending aortic dilatation.MethodsThe clinical data of patients with aortic aneurysm and aortic dissection who underwent surgery at Beijing Anzhen Hospital, Capital Medical University from 2010 to 2017 were retrospectively reviewed. After exclusion of patients with Marfan syndrome, heart valve and other diseases, 139 patients were divided into two groups: a simple ascending aorta dilatation group (56 patients) and a simple ascending aortic dissection group (83 patients). The ascending aortic diameter and postoperative outcomes of two groups were compared. ResultsThe inner ascending aortic diameter (57.30±9.41 mm vs. 50.72±9.53 mm, P <0.001) and the inner ascending aortic diameter index (31.12±5.38 vs. 27.22±6.40, P<0.001) in the simple ascending aorta dilatation group were significantly greater than those in the simple ascending aortic dissection group. For male patients, the results were similar (60.28±10.80 mm vs. 47.40±6.53 mm; 30.00±6.33 vs. 23.60±3.72, both P<0.001). But for the female patients, there was no significant difference between the two groups (54.90±7.47 mm vs. 53.81±10.84 mm; 32.03±4.37 vs. 30.58±6.56, both P>0.05). The mortality, the incidence of tracheotomy and postoperative reopen rate in the simple ascending aortic dissection group were higher.ConclusionIn this study, the inner diameter of the ascending aorta in the group of ascending aorta is mostly < 5.5 cm. In our opinion, the present surgical indication for Chinese patients with ascending aortic dilatation is not enough. In the future clinical studies, we also need to find more reasonable surgical indications.
