Abstract Purpose: The purpose of this study is to come up with new methods to quantitate the blood loss under endoscope and explore the influence of blood loss on percutaneous endoscopic lumbar discectomy (PELD). Methods: Clinical research and in-vitro experiment are combined. In the in-vitro experiment, 2.0 ml blood was diluted in different ratio to simulate the rinse solution of PELD, the hematocrit method (HCT-M) and red blood cell count method (RBC-M) were came up to estimate blood loss and the new methods were calibrated with the directly measurement method (Direct-M). In clinical research, 74 patients with L5/S1 disc herniation were treated with PELD, HCT-M and the empirical method (EMP-M) were used to estimate the blood loss under endoscope. According to blood loss, all patients were divided into group A (≤10 ml) and group B (>10 ml). The blood loss, operation time, fluoroscopy frequency, visual analog scale (VAS) and oswestry disability index (ODI) scores were compared between the two groups. Results: In the in-vitro experiment, the hematocrit of the rinse solution was always stable over time. The estimated blood loss by HCT-M was stable and quite approximate to actual blood volume (2.0 ml) whatever the blood dilution ratio, while according to RBC-M, the estimated blood loss was close to the actual blood volume only when the dilution ratio was greater than 300 times. In clinical research, the blood loss estimated by HCT-M was higher than that by EMP-M in both groups (P<0.05). There was a significant difference between group A and group B in blood loss (7.40±1.61 vs 19.91±10.94 ml), operation time (80.51±34.70 vs 136.51±41.88 min), and fluoroscopy frequency (6.92±1.52 vs 11.11±2.32 times) (P<0.05). The VAS and ODI scores in group B were higher than that in group A 1 week after operation (P<0.05), however the scores were not different between the two groups at pre-operation (P>0.05). Conclusion: HCT-M is a reliable method to estimate endoscopic blood loss in PELD. The amount of endoscopic blood loss affects the operative procedure in operation time and fluoroscopy frequency, as well as clinical effects in VAS and ODI scores after operation in short-term

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.

AbstractCementless bipolar hemiarthroplasty (BHA) recently gained popularity as a treatment for femur neck fracture (FNF), but there have been few studies comparing this with multiple screw fixation (MSF) in the elderly population. The purpose of this study is to compare (1) surgery-related parameters, (2) reoperation rate as a local complication, (3) in-hospital systemic complication rate, and (4) mortality rate at 1 year after MSF and cementless BHA in patients with FNF using nationwide data. Six-hundred sixty-six hips (aged ≥ 50 years) extracted from nationwide Hip Fracture Registry were included in this study (133 MSF and 533 cementless BHA). One hundred fifty-six hips were divided into nondisplaced FNF (Group A) and 510 into displaced FNF (Group B). We evaluated (1) surgery-related parameters (anesthesia type, time to surgery, operation time, estimated blood loss and volume of postoperative transfusion), (2) the rate of and reasons for reoperation, (3) the rate and type of in-hospital systemic complications and (4) one-year mortality rate after surgery. In Group A, MSF showed shorter operation time (p = 0.004) and lower incidence of in-hospital systemic complications (p = 0.003). In Group B, cementless BHA demonstrated lower reoperation rate than MSF (p < 0.001). In both Group A and B, cementless BHA was associated with higher estimated blood loss than MSF (p < 0.001). Based on findings in our study, MSF might be a more favorable option for nondisplaced FNF, whereas cementless BHA might be a better one for displaced FNF in patients older than fifty. Nevertheless, our nationwide study also showed that numbers of cementless BHAs were being performed for nondisplaced FNF even in teaching hospitals.

Place and Duration: Department of ENT and Headand Neck Surgery, Continental Medical College, Hospital Lahore, from 1 January 2015 to 30September 2015. Materials and Methods: This study included 164 patients of age group 4 to12 years of either gender undergoing tonsillectomy. The patients were divided into two equalgroups designated as A and B each having 82 patients using simple random sampling. Patientsin group A were operated for tonsillectomy by bipolar electrocautry while group B underwenttonsillectomy by cold steel dissection method. All patients in both groups were assessed foroperating time and intra-operative blood loss. Results: Out of 82 cases of Bipolar DissectionGroup 49(60%) patients were male and 33(40%) patients were female. Whereas in 82 casesof Cold Dissection Group 51(62%) patients were male and 31(38%) patients were female.Mean age of patients was 7.2(SD ± 1.97) years. Mean operation time was 15 minutes withstandard deviation ± 1.21 in group A as compared to group B where mean operation time was20 minutes with standard deviation ± 1.87. Mean blood loss was 7 ml with standard deviation± 2.53 in patients of group A as compared to Patients in group B who mean blood loss of 30ml with standard deviation ± 3.46. Group A had statistically significant lower operative time andblood loss than group B. Conclusion: Tonsillectomy with bipolar electro dissection method ismuch better than cold steel dissection method. It has an advantage of less blood loss duringsurgery. It significantly reduces intra operative time.

Abstract Background and purpose: There is no consensus regarding the appropriate treatment of sacral giant cell tumor (SGCT). This study is to compare oncological and neurological outcomes of SGCT managed by surgery and various adjunctive therapies.Methods: A total of 31 patients with SGCT were retrospectively studied. They were divided into two Groups. A: 13 patients underwent surgery plus SAE and radiotherapy; Group B: 18 patients underwent surgery plus one arterial embolization and denosumab. The postoperative functional outcomes, recurrence, mortality, and complications were compared.Results: The mean operation time (231±49min) and blood loss (3167±856mL) of group B were significantly less than those of group A (283±41min, 5054±689mL) (p<0.05). The average follow-up was 68.5 months. The neurologic function scores showed no significant difference. The recurrence rate of group B (11.2%) was much lower than that of group A (30.7%, p=0.17). The cumulative survival rate of group B was higher than that of group A (p=0.133).Conclusions: In comparison to other adjuvant therapies, one arterial embolization plus denosumab can reduce the intra-operative blood loss, shorten the operation time, and decrease the recurrence rate in patients with SGCT.

Objective. There is a steep learning curve with traditional percutaneous endoscopic lumbar discectomy (PELD). The aim of this study is to assess the safety and efficacy of PELD assisted by O-arm-based navigation for treating lumbar disc herniation (LDH).Methods. From September of 2017 to January of 2018, 118 patients with symptomatic LDH were enrolled in the prospective cohort study. The patients undergoing PELD with O-arm-based navigation technique were defined as group A (58 cases), and those undergoing traditional X-ray fluoroscopy method were defined as group B (60 cases). We recorded the operation time, cannula placement time, radiation exposure time, visual analog scale (VAS), Oswestry Disability Index (ODI), and Macnab criteria score of the 2 groups.Results. The average operation time (95.21 ± 19.05 mins) and the cannula placement time (36.38 ± 14.67 mins) in group A were significantly reduced compared with group B (operation time, 113.83 ± 22.01 mins, P<0.001; cannula placement time, 52.63 ± 17.94 mins, P<0.001). The learning curve of PELD in group A was steeper than that in group B and was lower in the relatively flat region of the end. There were significant differences of the clinical parameters at different time points (VAS of low back, P < 0.001; VAS of leg, P < 0.001; and ODI, P < 0.001). The VAS scores for low back pain and leg pain improved significantly in both groups after surgery and gradually improved as time went by. No serious complication was observed in any patients in either group.Conclusion. The study indicated that PELD assisted by O-arm navigation is safe, accurate, and efficient for the treatment of lumbar intervertebral disc herniation. It reshaped the learning curve of PELD, reduced the difficulty of surgery, and minimized radiation exposure to surgeons. This study was registered at Chinese Clinical Trail Registry (Registration Number:ChiCTR1800019586).

AbstractObjectiveThe aim of this study was to compare the differences between the no tympanomeatal flap approach and the tympanomeatal flap approach in endoscopic myringoplasty.MethodA total of 132 patients with tympanic membrane perforation were randomly divided into two groups: the no tympanomeatal flap approach group (group A, 56 ears) and the tympanomeatal flap approach group (group B, 76 ears). A comparison between the two groups was made.ResultsThe average operation time of group A was 36.00 ± 5.24 minutes, which was significantly shorter than that of group B, which was 43.89 ± 4.57 minutes (p = 0.002). The blood loss of group A was 5.08 ± 1.83 ml, which was significantly less than that of group B (9.67 ± 2.29 ml; p < 0.001). There were no differences in the degree of hearing improvement, the rate of hearing improvement, the dry ear time (when the external auditory canal and the operating cavity were dry) after operation and the success rate of tympanic membrane repair when compared between the two groups.ConclusionCompared with group B, group A (no tympanomeatal flap approach) can achieve the same effect but has the advantages of a shorter operation time and less blood loss during the operation.

Abstract Background The surgical approaches to thoracolumbar junction (T12-L1) tuberculosis were controversial. We aimed to compare the safety and efficacy of three different procedures through a multicentre retrospective study. Methods The medical records of thoracolumbar junction tuberculosis patients (n = 177) from January 2005 to January 2015 were collected and reviewed. Forty-five patients underwent anterior debridement and instrumented fusion (Group A), 52 underwent anterior combined with posterior debridement and instrumented fusion (Group B) and 80 underwent posterior-only debridement and instrumented fusion (Group C). Patients with neurological deficit were 10 in Group A, 23 in Group B, 36 in Group C. All patients had a standard preoperative and postoperative anti - tuberculous therapy regimen. Clinical outcomes, laboratory indexes and radiological evaluation of the three groups were compared. Operations at each centre were performed by the respective senior medical teams of the six different hospitals. Results All three surgical approaches achieved bone fusion and pain relief. Cases with neurological deficits had different degrees of improvement after surgery. The operative time was 330.2 ± 45.4 min, 408.0 ± 54.3 min, 227.9 ± 58.5 min, and the blood loss was 744.0 ± 193.8 ml, 1134.6 ± 328.2 ml, 349.8 ± 289.4 ml in groups A, B and C respectively. The average loss of correction was 5.5 ± 3.7° in group A, 1.6 ± 1.9° in group B, 1.7 ± 2.2° in group C, and the difference between groups except B vs C were of statistically significant (P < 0.05). Conclusions For patients with thoracolumbar junction (T12-L1) tuberculosis, the posterior-only procedure is the better than the anterior-only procedure in the correction of kyphosis and maintenance of spinal stability. The posterior-only procedure is recommended because it achieves the same efficacy as combined procedure with shorter operation time, less blood loss and trauma.

Abstract Background The surgical procedures for mid-thoracic spinal tuberculosis mainly include anterior transthoracic debridement and fusion and posterior transpedicular debridement and fusion. Until now, the surgical choice is still controversial. This study aims to compare the clinical efficacy of anterior transthoracic debridement and fusion with posterior transpedicular debridement and fusion in the treatment of mid-thoracic (T5–9) spinal tuberculosis in adult patients. Methods Eighty-seven cases with mid-thoracic spinal tuberculosis were treated with anterior transthoracic debridement and fusion (Group A, n = 39) and posterior transpedicular debridement and fusion (Group B, n = 48) from January 2007 to June 2014. Parameters including the operation time, blood loss, time of ESR and CRP decreasing to the normal level, time of abscess disappearance, time of bone graft fusion, rate of surgical complications, Visual Analog Scale (VAS) score, kyphosis angle and SF-36 scale were compared between two groups to evaluate their therapeutic effects. Results All patients were followed up for 5–10 years with the mean of 6.2 ± 1.1 years. No significant differences were observed regarding the gender composition ratio, age, course of disease, number of lesion segments, and preoperative indexes of ESR, CRP, VAS score, kyphosis angle and SF-36 scale between the two groups. Besides, no significant differences were observed regarding VAS score, kyphosis angle and SF-36 scale between the two groups in the 5th postoperative year (P > 0.05). However, the operation time (158.2 ± 10.7 min vs. 183.7 ± 14.1 min), blood loss (517.9 ± 76.5 ml vs.714.6 ± 57.4 ml), time of ESR (2.3 ± 1.1 months vs.3.1 ± 1.4 months) and CRP (1.1 ± 0.3 months vs.1.2 ± 0.6 months) decreasing to the normal level, time of abscess disappearance (2.7 ± 1.6 months vs.4.9 ± 1.9 months), and time of bone graft fusion (6.6 ± 0.8 months vs.8.0 ± 9.6 months) in Group A were less than those in Group B (P < 0.05). Conclusions Both anterior transthoracic debridement and fusion and posterior transpedicular debridement and fusion have a low risk of surgical complications and provide good quality of life for the patients with mid-thoracic (T5–9) spinal tuberculosis followed up in the mid-term. Moreover, the anterior procedure leads to early resolution of the disease and faster fusion.
