Abstract Background: Many methods have been proposed to increase cup coverage by host bone during primary total hip arthroplasty (THA) in hip osteoarthritis secondary to developmental dysplasia of hip (DDH). However, there was no study comparing results of controlled fracture of medial wall with structural autograft with bulk femoral head. Methods: 67 hips classified as Crowe II/III were retrospectively included in this cohort study, which consisted of 33 controlled fracture (group A) and 34 structural autograft (group B). The Harris Hip Scores (HHS) was recorded. The radiological assessments were analyzed. Also, complications are assessed. The paired sample t test was used for data analysis before and after operation, while independent sample T test was used for the comparison between the two groups. The Pearson chi-square test or Fisher exact test was used to analyze the qualitative comparative parameters. Kaplan-Meier was utilized in the analysis of survivorship with the end points as a revision for any component.Results: All patients were reconstructed acetabulum at anatomical location. HHS increased greatly for both groups (P=0.18). No statistic difference was observed for two groups in postoperative leg-length discrepancy ((0.51±0.29) cm for group A and (0.46±0.39) cm for group B, P=0.64 ), postoperative height of hip center ((2.25±0.42) cm for group A and (2.09±0.31) cm for group B, P=0.13), inclination of cup ((39±4)°for group A and (38±3)°for group B, P=0.65 ). The rate of cup coverage for group B ((94±2)% ) was better than group A ((91±5)%), ( P=.009). Rate of cup protrusio was (48±4)% for group A. For both groups, No statistic difference was observed in cup diameter (P＞.05), while group A showed less operation time than group B (P＜.001). No complications were observed at the latest follow-up. Conclusion: Controlled fracture of medial wall to increase cup coverage by host bone at anatomical location can act as an alternative technique for DDH Crowe II/III with advantage of shorter operation time and less technically demanding.

Objective To evaluate the influence of insufficient bone cement distribution on outcomes following percutaneous vertebroplasty (PVP). Methods This retrospective matched-cohort study included patients 50–90 years of age who had undergone PVP for single level vertebral compression fractures (VCFs) from February 2015 to December 2018. Insufficient (Group A)/sufficient (Group B) distribution of bone cement in the fracture area was assessed from pre- and post-operative computed tomography (CT) images. Assessments were before, 3-days post-procedure, and at the last follow-up visit (≥12 months). Result Of the 270 eligible patients, there were 54 matched pairs. On post-operative day 3 and at the last follow-up visit, significantly greater visual analogue scale (VAS) pain scores and Oswestry Disability Index (ODI) scores were obtained in Group B over Group A, while kyphotic angles (KAs) and vertebral height (VH) loss were significantly larger in Group A compared with Group B. Incidence of asymptomatic cement leakage and re-collapse of cemented vertebrae were also greater in Group A compared with Group B. Conclusions Insufficient cement distribution may relate to less pain relief and result in progressive vertebral collapse and kyphotic deformity post-PVP.

Study Design: Retrospective cohort study. Objectives: To investigate the effectiveness and safety of a gelatin–thrombin matrix sealant (GTMS) during microendoscopic laminectomy (MEL) for lumbar spinal canal stenosis (LSCS). Methods: This study included 158 LSCS cases on hemostasis-affecting medication who underwent MEL by a single surgeon between September 2016 and August 2020. Patients were divided into 2 groups depending on whether GTMS was used (37 cases, Group A) or not (121 cases, Group B). Perioperative data related to bleeding or postoperative spinal epidural hematoma (PSEH) was investigated. Clinical outcomes were evaluated using the Japanese Orthopedic Association (JOA) score for low back pain. Results: The mean intraoperative blood loss per level was greater in Group A (26.0 ± 20.3 g) than in Group B (13.6 ± 9.0 g), whereas the postoperative drainage volume was smaller in Group A (79.1 ± 42.5 g) than in Group B (97.3 ± 55.6 g). No revision surgeries for PSEH were required in Group A, while 2 (1.7%) revisions were required in Group B ( P = .957). The median JOA score improved significantly from the preoperative period to 1-year postoperatively in both Group A and B (total score, 16.0-23.5 and 17.0-25.0 points, respectively). Conclusions: The use of GTMS during MEL for LSCS may be associated with a reduction in postoperative drainage volume. The revision rate for PSEH was not affected significantly by the use of GTMS. Clinical outcomes (represented by the JOA score) were significantly improved after the surgery, regardless of GTMS use during MEL.

Introductions: Fever and sepsis after percutaneous nephrolithotomy (PCNL) secondary to urinary tract infection is a major determinant of overall post PCNL complications. This study aims to analyse infective complications after PCNL in relation to pre-operative urine culture status. Methods: A comparative analysis of post PCNL infective complications in pre-operative urine culture positive (Group A) and negative (Group B) was done for one year during June 2017 to May 2018 in department of urology, Bir Hospital, National Academy of Medical Sciences, Kathmandu, Nepal. Demographics, stone characteristics, mean operative time, post-operative hospital stay and post-operative complications as per Modified Clavien classification were compared between the two groups. Results: Out of total 136 PCNL patients, 51 were in Group A and 85 in Group B. Infective complications were significantly high, 28 (54.90%) in group A compared to 20 (23.53%) in group B, p=0.004. The most common isolate was Escherichia coli 19 (37.25%), sensitive to amikacin 37 (72.55%). The mean operation time, transfusion and hospital stay was not statically different in two groups. Morality occurred in 1 (1.96%) in group A. Conclusions: Infective complications were significantly high after PCNL in patients with preoperative positive urine culture, even when it was treated to sterile with sensitive antibiotics, compared to patients with preoperative negative urine culture.

Introduction: The aim of this study was to compare laparoscopic and open partial nephrectomy (PN) for renal tumors of high surgical complexity (PADUA score ⩾10). Methods: We retrospectively evaluated 93 consecutive patients who underwent PN at our department from January 2015 to September 2019. 21 patients underwent open partial nephrectomy (OPN) (Group A) and 72 underwent laparoscopic partial nephrectomy (LPN) (Group B). All OPNs were performed with a retroperitoneal approach, while all LPNs were performed with a transperitoneal approach by a single surgical team. Post-operative complications were classified according to the Clavien-Dindo system. Results: The two groups showed no difference in terms of patients’ demographics as well as tumor characteristics in all variables. Group A was found to be similar to group B in terms of operation time ( p = 0.781), conversion to radical nephrectomy ( p = 0.3485), and positive surgical margins ( p = 0.338) while estimated blood loss ( p = 0.0205), intra-operative ( p = 0.0104), and post-operative ( p = 0.0081) transfusion rates, drainage time ( p = 0.0012), pain score at post-operative day 1 (<0.0001) were significantly lower in Group B. The rate of enucleation and enucleoresection/polar resection was similar ( p = 0.1821) among the groups. Logistic regression analysis indicated that preoperative factors were not independently associated with the surgical approach. There was a statistically significant difference in complication rate (<0.0001) between the two groups even if no significant difference in terms of grade ⩾3 post-operative complications ( p = 0.3382) was detected. Discussion: LPN represents a feasible and safe approach for high complex renal tumors if performed in highly experienced laparoscopic centers. This procedure offers good intraoperative outcomes and a low rate of post-operative complications.

Abstract Purpose A multicentre, retrospective study was conducted to evaluate the safety and efficacy of different surgical techniques for thoracolumbar junction (T12-L1) tuberculosis. Methods The medical records of thoracolumbar junction tuberculosis patients (n = 257) from January 2005 to January 2015 were collected and reviewed. A total of 45 patients were operated on by an anterior approach (Group A), 52 by a combined anterior and posterior approach (Group B) and 160 by a posterior approach (Group C). Anti-tuberculosis therapy was performed both before and after surgery. Clinical outcomes, laboratory indexes and radiological results of the three groups were compared. Results All three surgical approaches achieved bone fusion, pain relief and neurological recovery. The mean loss of correction in group A at last follow-up was higher than in groups B and C (P < 0.05), and the difference between groups B and C was not significant (P > 0.05). The mean operation time and blood loss in group B were greater than in groups A and C. Conclusions For patients with thoracolumbar junction (T12-L1) tuberculosis, the posterior-only approach is superior to the anterior-only approach in the correction of kyphosis and maintenance of spinal stability. The posterior-only approach is recommended because it achieves the same efficacy as the anterior-only or combined approach but with shorter operation times, less trauma and less blood loss.

Abstract Background Erosive gastro-esophageal reflux disease (e-GERD) is associated with various symptoms caused by reflux of acid and gastric contents from the stomach to the esophagus. In general, it seems that as the duration of the disease is longer, surgical outcomes are inferior because of disease progression. The aim of this study is to evaluate the relationship between the disease duration and surgical outcomes of laparoscopic fundoplication (LF). Methods Two hundred and fifty-one (mean age was 53.4 years, male in 166) patients with e-GERD who underwent LF as an initial operation at our institution were extracted from the database. E-GERD was defined as equal to or more than grade A esophagitis by Los Angeles classification. These patients were divided into three groups by the length of disease duration: less than two years in Group A (n = 104), two to 5 years in Group B (n = 68) and equal to or more than 5 years in Group C (n = 79). We analyzed patients’ background, pre-operative symptoms, surgical outcomes, patients’ satisfaction and post-operative course. Before surgery, a standardized questionnaire was used to assess the degree of frequency and severity of symptoms (heartburn, regurgitation, dysphagia, vomiting and chest pain). Moreover, satisfaction with the operation was evaluated using the standardized questionnaire. Results Age and degree of acid reflux by pH-metry were significantly different among the three groups (P = 0.0054 and 0.0345, respectively). As to the pre-operative symptom score, the severity score of heartburn and the frequency score of regurgitation were significantly lower in Group A (P = 0.0225 and 0.031, respectively). Although operation time was significantly difference among the three groups (P = 0.0423), there were no differences in intraoperative blood loss, occurrence of peri-operative complications, post-operative course and patients’ satisfaction. Conclusion Although the patients who suffered equal to or over two years had more severe heartburn and regurgitation because of prolonged acid reflux, the duration of the disease does not seem to affect the surgical outcomes.

Abstract Background The aim of the present study was to establish an animal model of Yang-Monti ileal ureter-bladder anastomosis and Yang-Monti ileal ureter-ureteral anastomosis and compare the advantages and disadvantages of the two surgical methods. Methods Fourteen 12-month-old male Chinese miniature pigs weighing 21 ± 1.38 kg were randomly divided into two groups. Group A (n = 7) underwent end-to-end anastomosis of the left Yang-Monti ileal ureter, left ileal ureter and left lower ureter; group B (n = 7) underwent anastomosis of the left Yang-Monti ileal ureter, left ileal ureter and bladder. In both groups, the contralateral kidney was removed at 1 week postoperatively. The incision length and operation time of the two groups were compared. Changes in serum creatinine and urea nitrogen were observed preoperatively, and at 2, 6 and 12 weeks postoperatively. Venous pyelography and cystography were performed at 12 weeks postoperatively to determine the ureteral patency and vesicoureteral reflux. At 12 months postoperatively, urinary culture was performed, and the diameter and histological changes of the intestinal ureter were assessed. Results Surgery was successfully completed in all 14 pigs. In group A, one pig died due to an anesthetic accident, and one pig died from a lung infection on postoperative day 4. In group B, one pig died from adhesive intestinal obstruction on postoperative day 7. The overall survival rate was 78.6%, and the 11 surviving pigs had no urinary or intestinal fistulae. Compared with group B, group A had a significantly longer surgical incision (30.86 ± 2.41 cm versus 26.71 ± 3.64 cm; p = 0.01) and shorter operation time (181.29 ± 15.10 min versus 157.71 ± 20.49 min; p = 0.02). The serum creatinine and urea nitrogen concentrations did not significantly differ between groups. All pigs had normal renal function pre- and postoperatively. There was no stenosis or obstruction on venous pyelography. The narrowest diameter of the ureter was significantly smaller in group B (5.90 ± 0.30 mm) than in group A (7.26 ± 1.06 mm; p = 0.01), but no contrast agent returned to the upper urinary tract in either group. Escherichia coli was detected on urine culture. In group A, one pig had obstruction of the ureteral ureter, while another had stenosis of the lower ureteral anastomosis. In group B, one pig had pelvic and intestinal ureteral dilatation; however, all anastomoses were patent. The ileal ureteral diameter was significantly larger in group A (9.40 ± 2.35 mm) than group B (6.62 ± 0.37 mm; p = 0.02). Two pigs in group A had separation of the transitional epithelium and columnar epithelial mucosa, with granulation tissue hyperplasia. The pigs with stenosis and obstruction had smooth fibrous tissue and smooth muscle of the anastomosis. In both groups, the two types of epithelial tissue were close together, and the intestinal villi were mildly atrophied and shortened. Conclusions An animal model of Yang-Monti ileal ureter-bladder anastomosis was successfully established. Compared with Yang-Monti ileal ureter-ureteral anastomosis, Yang-Monti ileal ureter-bladder anastomosis is simpler, more reliable, and results in fewer complications.

Objective. In this randomized, nonblinded, controlled study, the feasibility and precision of “targeted percutaneous vertebroplasty” (“targeted PVP”) for osteoporotic vertebral compression fracture (OVCF) was evaluated. Methods. A total of 42 patients, aged 50 to 87 years, with OVCF were randomly divided into 2 groups: A and B. Group A underwent “targeted PVP,” and group B underwent traditional PVP with the guidance of C-arm fluoroscopy. Fluoroscopy times for skin puncture points (FTSPP), total radiation doses (TRD), total fluoroscopy times (TFT), and operation time were set as the main evaluation indicators. Results. FTSPP (1.52 ± 0.51 in group A vs 6.62 ± 2.58 in group B, U < .001), TRD (6.26 ± 1.51 in group A vs 11.32 ± 4.21 in group B, P < .001), TFT (16.57 ± 2.79 in group A vs 26.05 ± 6.18 in group B, P < .001), and operation time (20.05 ± 3.38 in group A vs 25.43 ±5.11 in group B, U < .001) were statistically different in the 2 groups. The incidence of cement leakage that occurred in group A (1/21, 4.76%) was significantly less than that in group B (9/21, 42.9%, P < 0.05). Conclusions. “Targeted PVP” may achieve (1) less skin positioning fluoroscopy times, less total fluoroscopy times and dose, shorter operation time, which is more precise than traditional PVP; (2) less incidence of cement leakage; and (3) visualization of the fractured vertebra, which is probably more valuable for the treatment of complicated OVCF patients.
