Coblation versus cold dissection in paediatric tonsillectomy: a systematic review and meta-analysis

AbstractBackgroundCold dissection is the most commonly used tonsillectomy technique, with low post-operative haemorrhage rates. Coblation is an alternative technique that may cause less pain, but could have higher post-operative haemorrhage rates.ObjectiveThis study evaluated the peri-operative outcomes in paediatric tonsillectomy patients by comparing coblation and cold dissection techniques.MethodsA systematic review was conducted of all comparative studies of paediatric coblation and cold dissection tonsillectomy, up to December 2018. Any studies with adults were excluded. Outcomes such as pain, operative time, and intra-operative, primary and secondary haemorrhages were recorded.ResultsSeven studies contributed to the summative outcome. Coblation tonsillectomy appeared to result in less pain, less intra-operative blood loss (p < 0.01) and a shorter operative time (p < 0.01). There was no significant difference between the two groups for post-operative haemorrhage (p > 0.05).ConclusionThe coblation tonsillectomy technique may offer better peri-operative outcomes when compared to cold dissection, and should therefore be offered in paediatric cases, before cold dissection tonsillectomy.

Abstract Aims Electrocautery (EC) remains the dominant dissection tool in modified radical mastectomy (MRM) for breast cancer. However, ultrasonic dissection devices (UDD) have emerged as popular alternatives on the basis that their mechanism of action limits tissue damage resulting in decreased blood loss, seroma formation and post-operative drainage. A systematic review and meta-analysis was performed to compare surgical outcomes for EC versus UDD in MRM surgery. Methods MEDLINE, EMBASE, PubMed and the Cochrane Database were searched and a comprehensive systematic review and meta-analysis performed according to PRISMA guidelines, comparing EC versus UDD in MRM for breast cancer. Outcomes of interest were post-operative drainage, incidence of seroma, intra-operative blood loss and operative time. Meta-analysis was performed using a random effects model to aggregate the data. Odds ratios (OR) were used as the summary statistic for dichotomous data and mean difference (MD) for continuous data. Data heterogeneity was assessed using the I2 statistic. Results Nineteen eligible peer-reviewed studies were analysed involving 1501 patients, UDD:744 EC:757. We demonstrated that in MRM, UDD significantly reduced post-operative drainage (MD = 312.26, 95% confidence interval (CI): 102.59-521.93, p = 0.004); seroma (OR = 0.51, 95% CI: 0.39-0.68, p < 0.00001) and intra-operative blood loss (MD = 111.68, 95% CI: 84.56-138.8, p < 0.00001) with no significant difference in operative time between the two techniques (MD = 0.32 (11.3-11.94), p = 0.96. Conclusion Using UDD in MRM for breast cancer presents significant advantages in decreasing post-operative drainage, seroma and intra-operative blood loss, without lengthening operating time compared to EC. It therefore appears favourable, however further cost-effectiveness analysis would be beneficial to guide selection.

OBJECTIVES: To conduct a prospective randomized controlled study presenting and comparing bipolar radiofrequency dissection tonsillectomy (BRDT) to cold dissection tonsillectomy (CDT) regarding intra-operative blood loss, operative time, postoperative pain, and postoperative complications including hemorrhage. MATERIALS AND METHODS: From January 2004 to March 2005, 200 children planned to undergo tonsillectomy were included in this study. Children were prospectively randomized into two equal groups: bipolar radiofrequency dissection tonsillectomy and cold dissection tonsillectomy. The operative time and intraoperative blood loss were recorded. Children were asked to record their pain on a standardized visual analog scale on days 1, 4, 7, and 14. All children were reviewed on the 4th, 7th, and 14th day after surgery. Postoperative complications were recorded and dealt with. RESULTS: There was a shorter operative time (mean 8.5 minutes, P < 0.001) in the radiofrequency group. BRDT showed a decrease of 7 minutes in the mean when compared to the CDT group. The amount of blood lost during BRDT was minimal (mean 13 cc), with a mean difference of 69 cc when compared to CDT ( P < 0.001). There was no statistical significant difference in pain score between the two groups except in the first postoperative day where the BRDT demonstrated a statistically significant lower parameters ( P < 0.05). No evidence for statistically significant difference between the two groups regarding postoperative complications. CONCLUSION: BRDT is a new, easy, and safe technique that offers a complete eradication of the tonsillar disease, short operating time, minimal intra-operative blood loss, and a suitable cost with no additional increase in postoperative pain and hemorrhage when compared to the conventional CDT. Our experience promotes BRDT as the preferred method of tonsillectomy. EBM RATING: A

Abstract Objective The Harmonic Scalpel and Ligasure (Covidien) devices are commonly used in head and neck surgery. Parotidectomy is a complex and intricate surgery that requires careful dissection of the facial nerve. This study aimed to compare surgical outcomes in parotidectomy using these haemostatic devices with traditional scalpel and cautery. Method A systematic review of the literature was performed with subsequent meta-analysis of seven studies that compared the use of haemostatic devices to traditional scalpel and cautery in parotidectomy. Outcome measures included: temporary facial paresis, operating time, intra-operative blood loss, post-operative drain output and length of hospital stay. Results A total of 7 studies representing 675 patients were identified: 372 patients were treated with haemostatic devices, and 303 patients were treated with scalpel and cautery. Statistically significant outcomes favouring the use of haemostatic devices included operating time, intra-operative blood loss and post-operative drain output. Outcome measures that did not favour either treatment included facial nerve paresis and length of hospital stay. Conclusion Overall, haemostatic devices were found to reduce operating time, intra-operative blood loss and post-operative drain output.

Objective The current guidelines recommend that potassium iodide be given in the immediate preoperative period for patients with Graves’ disease who are undergoing thyroidectomy. Nonetheless, the evidence behind this recommendation is tenuous. The purpose of this study is to clarify the benefits of preoperative iodine administration from published comparative studies. Data Sources We searched PubMed, Embase, Cochrane, and CINAHL from 1980 to June 2018. Review Methods Studies were included that compared preoperative iodine administration and no premedication before thyroidectomy. For the meta-analysis, studies were pooled with the random-effects model. Results A total of 510 patients were divided into the iodine (n = 223) and control (n = 287) groups from 9 selected studies. Preoperative iodine administration was significantly associated with decreased thyroid vascularity and intraoperative blood loss. Significant heterogeneity was present among studies. We found no significant difference in thyroid volume or operative time. Furthermore, the meta-analysis showed no difference in the risk of postoperative complications, including vocal cord palsy, hypoparathyroidism/hypocalcemia, and hemorrhage or hematoma after thyroidectomy. Conclusion Preoperative iodine administration decreases thyroid vascularity and intraoperative blood loss. Nonetheless, it does not translate to more clinically meaningful differences in terms of operative time and postoperative complications.

Abstract Background A systematic review and meta-analysis was conducted to compare the safety and efficiency of nephroscopy and cystoscopy in transurethral cystolithotripsy (TUCL) for bladder stones (BS). Methods The PubMed, Web of Science, Embase, EBSCO, and Cochrane Library databases were searched up to January 2021 for studies assessing the effect of different types of endoscopes among patients who underwent TUCL. The search strategy and study selection process were in accordance with the PRISMA statement. Results Five randomized controlled trials were included in the meta-analysis. The results showed no difference in stone-free rate (RR = 1.00, CI = 0.98–1.02, p = 1.00) between the two groups and nonsignificant heterogeneity (I2 = 0%, p = 1.00), and all patients were rendered stone free. Use of the nephroscope significantly shortened the operative time compared with the cystoscope group (RR= − 26.26, CI = − 35.84 to − 16.68, p < 0.00001), and there was significant heterogeneity (I2= 87%, p < 0.00001). There was no significant difference in mean urethral entries (RR = 0.66, CI = − 0.71 to − 2.04, p = 0.35), hospitalization (MD = 0.08, 95% CI = − 0.07 to 0.23, p = 0.31) or total complication rate (RR=1.37, 95% CI = 0.47–4.00, p = 0.56) between the two groups. Conclusions In conclusion, this systematic review demonstrates that both nephroscopy and cystoscopy have high stone clearance efficiency, low rates of complications and short hospitalizations. The mean urethral entries depend on the treatment method for large stone fragments. However, the use of nephroscopy can significantly reduce the operative time.

ABSTRACT The number of fixed segments in the surgical treatment of thoracolumbar burst fractures remains controversial. This study aims to compare the results of short and long fixation in thoracolumbar burst fractures through a meta-analysis of studies published recently. MEDLINE and Cochrane databases were used. Randomized controlled trials and non-randomized comparative studies (prospective and retrospective) were selected. Data were analyzed with the software Review Manager. There was no statistically significant difference in the Cobb angle of preoperative kyphosis. Long fixation showed lower average measurements postoperatively (MD = 1.41; CI = 0.73-2.08; p<0.0001) and in the last follow-up (MD = 3.98; CI = 3.22-4.75; p<0.00001). The short fixation showed the highest failure rates (RD = 4.03; CI = 1.33-12.16; p=0.01) and increased loss of height of the vertebral body (MD = 1.24; CI = 0.49-1.98; p=0.001), with shorter operative time (MD = -24.54; CI = -30.16 - -18.91; p<0.00001). There was no significant difference in blood loss and clinical outcomes. The high rates of kyphosis correction loss with short fixation and the lower correction rate in the immediate postoperative period were validated. There was no significant difference in the blood loss rates because arthrodesis was performed in a short segment in the analyzed studies. The short fixation was performed in a shorter operative time, as expected. No study has shown superior clinical outcomes. The short fixation had worse rates of kyphosis correction in the immediate postoperative period, and increased loss of correction in long-term follow-up, making the long fixation an effective option in the management of this type of fracture.

This systematic review and meta-analysis was conducted to evaluate the safety of gelatin versus hydroxyethyl starches (HES) and crystalloids when used for cardiopulmonary bypass (CPB)-priming in cardiac surgery. MEDLINE (Pubmed), Embase and CENTRAL were searched. We included only randomized, controlled trials comparing CPB-priming with gelatin with either crystalloids or HES-solutions of the newest generation. The primary endpoint was the blood loss during the first 24 hours. Secondary outcomes included perioperative transfusion requirements, postoperative kidney function, postoperative ventilation times and length of stay on the intensive care unit. Sixteen studies were identified, of which only ten met the inclusion criteria, representing a total of 824 adult patients: 4 studies compared gelatin with crystalloid, and 6 studies gelatin with HES priming. Only 2 of the studies comparing HES and gelatin reported postoperative blood loss after 24 hours. No significant difference in postoperative blood loss was found when results of both studies were pooled (SMD -0.12; 95% CI: -0.49, 0.25; P=0.52). Likewise, the pooled results of 3 studies comparing gelatin and crystalloids as a priming solution could not demonstrate significant differences in postoperative bleeding after 24 hours (SMD -0.07; 95% CI: -0.40, 0.26; P=0.68). No differences regarding any of the secondary outcomes could be identified. This systematic review suggests gelatins to have a safety profile which is non-inferior to modern-generation tetrastarches or crystalloids. However, the grade of evidence is rated low owing to the poor methodological quality of the included studies, due to inconsistent outcome reporting and lack of uniform endpoint definitions.

OBJECTIVE Several approaches have been studied for internal fixation of the spine using pedicle screws (PSs), including CT navigation, 2D and 3D fluoroscopy, freehand, and robotic assistance. Robot-assisted PS placement has been controversial because training requirements, cost, and previously unclear benefits. This meta-analysis compares screw placement accuracy, operative time, intraoperative blood loss, and overall complications of PS insertion using traditional freehand, navigated, and robot-assisted methods. METHODS A systematic review was performed of peer-reviewed articles indexed in several databases between January 2000 and August 2021 comparing ≥ 2 PS insertion methods with ≥ 10 screws per treatment arm. Data were extracted for patient outcomes, including PS placement, misplacement, and accuracy; operative time, overall complications, intraoperative blood loss, postoperative hospital length of stay, postoperative Oswestry Disability Index (ODI) score, and postoperative visual analog scale (VAS) score for back pain. Risk of bias was assessed using the Newcastle-Ottawa score and Cochrane tool. A network meta-analysis (NMA) was performed to estimate PS placement accuracy as the primary outcome. RESULTS Overall, 78 studies consisting of 6262 patients and > 31,909 PSs were included. NMA results showed that robot-assisted and 3D-fluoroscopy PS insertion had the greatest accuracy compared with freehand (p < 0.01 and p < 0.001, respectively), CT navigation (p = 0.02 and p = 0.04, respectively), and 2D fluoroscopy (p < 0.01 and p < 0.01, respectively). The surface under the cumulative ranking (SUCRA) curve method further demonstrated that robot-assisted PS insertion accuracy was superior (S = 0.937). Optimal screw placement was greatest in robot-assisted (S = 0.995) placement, and misplacement was greatest with freehand (S = 0.069) approaches. Robot-assisted placement was favorable for minimizing complications (S = 0.876), while freehand placement had greater odds of complication than robot-assisted (OR 2.49, p < 0.01) and CT-navigation (OR 2.15, p = 0.03) placement. CONCLUSIONS The results of this NMA suggest that robot-assisted PS insertion has advantages, including improved accuracy, optimal placement, and minimized surgical complications, compared with other PS insertion methods. Limitations included overgeneralization of categories and time-dependent effects.

Background: The aim of our study is to systematically review the existing evidence on the role of corticosteroids in patients undergoing functional endoscopic sinus surgery (FESS). Methodology: Systematic search of MEDLINE (1950- 2014), EMBASE (1980-2014), metaRegister, Cochrane Library and ISI conference proceedings was carried out. Results: Eighteen randomised controlled trials with 1309 patients were included. Use of local and/or systemic corticosteroids with FESS was reported in four categories; operative, anaesthesia related, post-operative outcomes and risk of recurrence. Meta-analysis for operative outcomes demonstrated that, mean operative time (MD -10.70 minutes; 95% CI -15.86, -5.55; P <0.0001) and mean estimated blood loss (MD -28.32 mls; 95% CI -40.93, -15.72; P <0.0001) was significantly lower; and surgical field quality (MD -0.81; 95% CI -1.32, -0.30; P = 0.002) was significantly better in corticosteroid group. Meta-analysis showed that post-operative endoscopic scores (SMD -0.39; 95% CI -0.60, -0.17; P = 0.0004) were significantly better in corticosteroid group compared to no corticosteroid group. There was no increase in risk of sinusitis (RR 0.64; 95% CI 0.32, 1.30; P = 0.22) between use of corticosteroids and no corticosteroids; There was no significant difference in recurrence risk of chronic rhinosinusitis (CRS) in mixed population studies (RR 0.77; 95% CI 0.35, 1.70; P = 0.52) between the two groups but analysis of studies reporting on chronic rhinosinusitis with nasal polyps (CRSwNP) (RR 0.64;95% CI 0.45,0.91;P=0.01) showed significant difference in favour of the corticosteroid group. Conclusion: Pre-operative use of local and/or systemic corticosteroids in FESS, results in significantly reduced blood loss, shorter operative time and improved surgical field quality. Studies are limited on the intra-operative use of corticosteroids to reduce postoperative pain. Postoperative corticosteroids improve postoperative endoscopic scores in CRS and recurrence rates in cases of CRSwNP.
