OBJECTIVES/HYPOTHESIS: Coblation tonsillectomy is a recently introduced surgical technique. To measure its benefits against traditional tonsillectomy techniques, it is necessary to compare their complication rates. The study aims to identify differences in reactionary and secondary hemorrhage proportions, comparing coblation with dissection tonsillectomy. STUDY DESIGN: Prospective observational cohort study. METHODS: Rates of reactionary and delayed postoperative hemorrhage were measured, comparing 844 coblation tonsillectomies with a control group of 743 tonsillectomies performed by blunt dissection with bipolar diathermy hemostasis. RESULTS: The secondary hemorrhage rate with coblation-assisted tonsillectomy was 2.25% compared with 6.19% in the control group (P <.05). The rate of secondary hemorrhage in children following coblation tonsillectomy was 0.95% compared with 4.77% in the control group (P <.05). The difference was also significant (P <.05) in the adult population (4.40% vs. 8.81%, respectively). No difference was found in the reactionary hemorrhage proportions. CONCLUSION: In the study, coblation tonsillectomy was associated with a lesser incidence of delayed hemorrhage, more significantly in the pediatric population. The new technique using tissue coblation for tonsil dissection offers significant advantages in the postoperative period compared with dissection tonsillectomy with bipolar diathermy hemostasis. Coblation is associated with less postoperative pain and early return to daily activities. Also, there are fewer secondary infections of the tonsil bed and significantly lower rates of secondary hemorrhage with coblation. These results and the disposable nature of the coblation equipment promote coblation tonsillectomy as the authors' preferred dissection method. 相似文献

OBJECTIVES: Investigation of the occurrence of postoperative hemorrhage after tonsillectomy and risk factors for these complications. STUDY DESIGN: Prospective National Audit with electronic web-based data collection from the National Health Service and independent hospitals in England and Northern Ireland. METHODS: Consenting patients undergoing tonsillectomy between July 2003 and September 2004 were included. A central database of patient and surgical variables was developed for analysis of primary and secondary postoperative hemorrhage and development of risk models for tonsillectomy complications. RESULTS: The Audit received data from 277 hospitals in England and Northern Ireland on 40,514 patients. Analysis was conducted on 33,921 (84%) who gave consent. Over the whole Audit 1,197 (3.5%) postoperative hemorrhages were recorded. One hundred eighty-eight (0.6%) patients sustained a primary hemorrhage and 1,033 (3%) a secondary hemorrhage (24 had both). Elevated hemorrhage rates were observed in tonsillectomies performed using diathermy for dissection and hemostasis compared with cold steel dissection and ties for hemostasis. National guidance issued midway through the Audit influenced practice and reduced hemorrhage rates. Risk models for postoperative hemorrhage were developed incorporating the effect of the guidance. For hemorrhage, compared with the cold steel group, bipolar diathermy tonsillectomy had an odds ratio of 2.47 (1.81-3.36), P < .0001, and bipolar diathermy scissors tonsillectomy an odds ratio of 3.20 (2.09-4.90), P < .0001. Use of bipolar diathermy for hemostasis only after cold steel dissection carried an intermediate risk, odds ratio 1.57 (1.16-2.13), P = .004. CONCLUSIONS: The results confirm that "hot" tonsillectomy techniques carry a substantially elevated risk of postoperative hemorrhage when diathermy is used as a dissection tool in tonsillectomy. 相似文献

Tonsillectomy despite being less performed nowadays still is a very common surgery performed by ENT surgeons. The use of various modalities like bipolar diathermy, laser, cryosurgery, radiofrequency and ionic coblation for hemostasis in tonsillectomy remains controversial so far. A thorough scan of literature comparing the ligation with diathermy has been presented. In this prospective study, we analysed 50 patients undergoing tonsillectomy by dissection method. Right sided tonsillectomies act as study group (bipolar diathermy used) and left sided tonsillectomies as the control group (ligation for hemostasis used). The aim of our study is to compare the amount of blood loss, number of ligatures applied, average time taken and incidence of postoperative haemorrhage following the use of ligation and bipolar diathermy. The study found that diathermy hemostatic technique is associated with a quicker procedure, less intraoperative blood loss, comparable postoperative pain. 相似文献

CONCLUSION: There is no increased risk of postoperative haemorrhage for abscess tonsillectomies in comparison to elective tonsillectomies. OBJECTIVE: There is still controversy as regards the optimal management of peritonsillar abscess. Opponents of tonsillectomy à chaud cite an increased postoperative bleeding risk. Most authors who compared the risks of postoperative haemorrhage after tonsillectomy à chaud and tonsillectomy à froid did not take into consideration criteria such as the age and gender of the patients or the experience of the surgeon. We aimed to eliminate this bias by performing a retrospective study in which a large series of abscess tonsillectomies were compared with an age- and gender-matched group of elective tonsillectomies. MATERIAL AND METHODS: All patients had been operated on at the Department of Otorhinolaryngology, University of Duisburg-Essen between March 1994 and August 2000. There were 350 patients in the abscess tonsillectomy group (61% male, 39% female; mean age 31.8 years; range 3-88 years) and 311 in the elective tonsillectomy comparison group (61% male, 39% female; mean age 30.0 years; range 2-83 years). RESULTS: In the abscess tonsillectomy group, 9 patients (2.6%; confidence level 1.1-4.8%) had postoperative haemorrhages which required treatment under general anaesthesia, compared to 17 (5.5%; confidence level 3.2-8.6%) in the age- and gender-matched group of "selected" elective tonsillectomies. The difference between these two rates was not significant (p = 0.056). The fairly high rate of haemorrhages in the elective tonsillectomy group was mainly due to the effect of the age-matching procedure, which excluded a considerable number of usually unproblematic tonsillectomies for tonsillar hyperplasia in young children. Moreover, our results show that there is a learning curve for surgeons performing tonsillectomies with regard to postoperative haemorrhages. 相似文献

CONCLUSION: A significant reduction in post-tonsillectomy secondary haemorrhage rate was observed after coblation tonsillectomy was abandoned in our department. OBJECTIVE: Comparison of the postoperative haemorrhage rate following coblation tonsillectomy and routine dissection tonsillectomy. PATIENTS AND METHODS: This was a retrospective study. In the first audit period, 441 sequential tonsillectomies between January and September 2002 were reviewed. Coblation was compared with cold steel and diathermy dissection with either ties and/or diathermy used for haemostasis. Coblation tonsillectomy was subsequently abandoned in our unit and, in the second audit period, all tonsillectomies (n=416) between July 2003 and August 2004 were included. Statistical analysis was performed using the chi2 test. RESULTS: The overall primary haemorrhage rate in the first audit cycle was 1.8% (8/441). In the second cycle with no coblation procedures, 1.4% of patients (6/416) suffered from primary haemorrhage (c.f. 8/441 (1.8%) in the first cycle, p=0.666). Secondary haemorrhage, was seen among 15.4% of patients (68/441) in the first audit cycle. In the second cycle, after coblation was discontinued, the secondary haemorrhage rate fell significantly (p<0.001) to 5.8% (24/416). A breakdown of the results of cold steel/diathermy and coblation techniques in both adults and children is also presented. 相似文献

OBJECTIVE: To examine the incidence of postoperative bleeding after coblation and noncoblation tonsillectomy and to use postoperative bleeding as an outcome measure to determine the presence of a learning curve with this new surgical technique. STUDY DESIGN: A retrospective review of records from January 1999 to April 2003 to determine type of tonsillectomy performed and the presence of postoperative bleeding. A chi-square analysis was used to determine a statistical difference between the postoperative bleed rate of coblation and noncoblation procedures. The examined time period was divided into 3-month intervals, and the coblation postoperative bleeds were tallied for each interval. The Cochraine-Armitage test of linear trend was used to assess change in the postoperative bleeds. RESULTS: One thousand seven hundred sixty-two tonsillectomies were performed. The postoperative bleed rate for noncoblation tonsillectomy was 6.1% (74/1,216). The bleeding rate for coblation tonsillotomy was 5.9% (18/303) and 5.4% (13/239) for coblation tonsillectomy. There was no statistical difference (P = .93) between bleed rates for coblation versus noncoblation techniques. There was no difference in the need for operative intervention to control postoperative bleeding: 16.2% (12/74) for noncoblation technique and 25.85 (8/31) for coblation procedures (P = .25). The postoperative coblation bleed rates for the 3-month periods did not reveal an increasing or decreasing trend in the postoperative bleed rate (P = .49). CONCLUSION: Coblation is a safe procedure for performing tonsil surgery with no significant difference in postoperative bleeding from previous techniques and no increased need for operative intervention to control postoperative bleeding. A learning curve could not be identified when using postoperative bleeding as an outcome measure for coblation tonsillectomy. 相似文献

Tonsillectomy is a common otolaryngological procedure and is associated with a small risk of postoperative pharyngeal haemorrhage. This study compares secondary post tonsillectomy haemorrhage rates between two operative techniques: diathermy tonsillectomy and diathermy tonsillectomy with tonsillar bed oversew. A total of 424 patients underwent tonsillectomies with or without other procedures such as adenoidectomy and grommet insertion by two ears, nose and throat surgeons at three hospitals from May 2012 to July 2013. A diathermy tonsillectomy was performed in 266 patients, while a diathermy tonsillectomy with tonsillar bed oversew was performed in 158 patients. All patients were followed up within 2–4 weeks of surgery. Primary haemorrhage did not occur in either surgical technique groups. Secondary haemorrhage occurred in 20 patients (7.52 %) in the diathermy tonsillectomy group and in 9 patients (5.70 %) in the diathermy with tonsillar bed oversew group. This result was not significantly different (OR = 0.74, 95 % CI 0.33–1.67, p = 0.47). Sex, age, indication for surgery and whether or not a tonsillectomy was performed alone or with other procedures were not significant factors for secondary haemorrhage. In summary, routine tonsillar bed oversew after diathermy tonsillectomy does not reduce the risk of secondary tonsillar haemorrhage. 相似文献

ObjectiveThis study aimed to evaluate current adult tonsillectomy indications along with risk factors associated with postoperative complications.MethodsIn this retrospective chart review, demographic, clinical, and surgical data were collected from 2004 to 2020 of adult patients who underwent tonsillectomy. Indications for surgery were categorized as infectious etiology, biopsy, obstructive sleep apnea (OSA), and tonsillar stones. Data regarding postoperative hemorrhage, emergency department (ED) visits, and readmissions were collected. Multivariable logistic regression models were used to evaluate factors associated with postoperative complications.Results574 adults (mean age 32 years, 69.9% F vs. 30.1% M) were included. The most common indication was infections (62.2%), followed by biopsy (26.5%), tonsillar stones (6.8%), and OSA (4.5%). The highest frequency of postoperative bleeds (17.9%) occurred in the tonsillar stones cohort; however, the indication for surgery was not a significant predictor on multivariate analysis. Male sex and younger age were independent predictors of postoperative bleeding, while younger age was a significant predictor of postoperative ED visits. There was a significant linear trend of an increasing proportion of tonsillectomies performed for tonsillar stones compared to other indications for 2011–2019.ConclusionInfectious etiology was the most common indication for tonsillectomy. Indication for surgery was not a significant predictor of postoperative bleeding; however, male sex and younger age had higher odds of postoperative bleeding. The proportion of tonsillectomies performed for tonsillar stones was steadily increasing. 相似文献

After the surgical procedure of tonsillectomy, hemorrhage ranks among its serious postoperative complications. In this systematic
review, we analyze hemorrhage following tonsillectomies performed using the coblation technique. 24 prospective, randomized,
and controlled studies were included in the meta-analysis. Data of 796 patients who had undergone coblation tonsillectomy
were analyzed. Hemorrhages occurred in 33 patients: 2 classified as primary and 26 as secondary hemorrhages. 5 could not be
classified into either group. Overall, the total hemorrhage rate for the coblation procedure was 4.1% with a 95% confidence
interval from 2.8 to 5.5%. The overall hemorrhage rate of 4.1% found in this meta-analysis shows that coblation is a safe
and effective technique for tonsillectomies with a secondary bleeding rate similar to what is reported for comparable techniques
such as bipolar diathermia. 相似文献

BACKGROUND: Tonsillectomy requires an efficient intra- and postoperative hemostasis. The ultrasonically activated scalpel (UAS) uses high-frequency ultrasonic energy to perform tissue dissection and coagulation simultaneously. The present prospective study represents the first published results of UAS in tonsillectomy. METHOD: 60 patients with tonsillectomy were examined in regard of intra- and postoperative hemostasis, wound healing and postoperative pain. Also, the quality of the histopathological specimen was evaluated. RESULTS: In 90% of tonsillectomies by UAS efficient intraoperative hemostasis did not require suture ligature. In 10% additional ligation was required for reason of arterial bleeding. Postoperative bleeding did not occur at all, wound healing was uneventful. Surgery related postoperative pain was not intensified. The histopathological evaluation of specimen was not impaired. CONCLUSION: The UAS offers a tissue dissection with efficacious intra- and postoperative hemostasis. Compared to the conventional tonsillectomy the ultrasonical technique of tonsillectomy has especially in children, in anaemic patients and in the surgery of tonsillar malignomas significant advantages. 相似文献

We performed a prospective randomized study in 179 patients to examine the second-generation surgical fibrin sealant Quixil as an effective substitute for different types of electrocautery in tonsillectomy and adenoidectomy. We compared the rates of hemorrhagic complications in a group with bipolar or needle point electrocautery and in a group in whom fibrin glue was used to stop intraoperative bleeding and to prevent postoperative bleeding. The operations were performed under general anesthesia in typical fashion with sharp dissection. For the control group, hemostasis was achieved by bipolar or needle point electrocautery. For the fibrin glue group, hemostasis was achieved by spraying Quixil fibrin glue approximately 0.5 mL to each tonsillar fossa and 0.5 mL to the nasopharynx (in adenoidectomy). The results were excellent in all the patients of the fibrin glue group, with complete hemostasis and resolution of the major symptoms. In this group, the intraoperative blood loss averaged 15 mL in tonsillectomy and 9 mL in adenoidectomy. There were no cases of postoperative hemorrhage or any other complications. The electrocautery group required a longer time for healing, and its intraoperative blood loss (tonsillectomy) averaged 29 to 33 mL. The incidence of posttonsillectomy bleeding in this group was 4.35% (4 patients). Three patients (3.26%) had primary hemorrhage (bleeding that occurs within the first 24 hours of surgery), and 1 patient (1.09%) had secondary hemorrhage (bleeding that occurs after the first 24 hours). We conclude that Quixil fibrin glue application to the operative sites in tonsillectomy and adenoidectomy provides effective hemostasis and sealing with good systemic and local compatibility. With the help of Quixil, we minimized surgical trauma and achievedabsolute hemostasis at the same time. We found this fibrin glue to be a more convenient and effective hemostatic sealant than bipolar or needle point coagulation. 相似文献

Tonsillectomy using local anesthesia (local tonsillectomy) is a safe and effective alternative to general anesthesia in the healthy cooperative teenage or adult patient. This retrospective analysis involved 64 local tonsillectomies performed over the past 7 years in a minor operating room using only local anesthesia with intravenous sedation. Operations were performed by residents in training as well as by experienced head and neck surgeons. Blood loss, morbidity, complications, and patient satisfaction were reviewed and compared with tonsillectomies done under general anesthesia. The average blood loss was 42 mL in the local tonsillectomy group with no cases of postoperative hemorrhage, compared with 198 mL in the general anesthesia group with two cases of postoperative hemorrhage. There was one major complication related to postoperative antibiotic use in the local anesthesia group, and follow-up interviews revealed that patients were satisfied with the procedure and would recommend and choose local anesthesia again. We conclude that local tonsillectomies have high patient acceptance and are associated with minimal morbidity and complications. Furthermore, they are cost-effective. 相似文献

OBJECTIVE: To evaluate bipolar scissors tonsillectomy by comparing it with traditional cold dissection tonsillectomy. STUDY DESIGN: A prospective, randomized, multi-unit study. SETTINGS: Belfast City Hospital, Royal Victoria Hospital Belfast, and Ulster Hospital Dundonald. PATIENTS: Two hundred consecutive patients undergoing tonsillectomy for recurrent or chronic tonsillitis between March 2000 and September 2000. OUTCOME MEASURES: (1) Intraoperative bleeding, (2) operative time, (3) postoperative pain, and (4) complication rates, including primary and secondary hemorrhage. RESULTS: Seventeen patients were excluded from the study for various reasons. The mean age of the study population was 22 years (range, 10-54 y). Seventy-two percent of patients were female. Twenty-seven percent of patients were children aged 16 years or under. Median intraoperative blood loss was 5 mL for bipolar scissors tonsillectomy and 115 mL for cold dissection tonsillectomy (P < .001). The mean operative time was 13 minutes for bipolar scissors tonsillectomy compared with 20 minutes for the cold dissection method (P < .001). There was no statistically significant difference in the pain scores between the two methods (independent samples t = 1.35; P > .05). The overall primary hemorrhage rate was 2.1%, whereas the overall secondary hemorrhage rate was 16.9%. The hospital readmission rate was 10.3%. The primary and secondary hemorrhage rates were unaffected by the surgical method. CONCLUSIONS: Bipolar scissors tonsillectomy is a safe technique with a similar morbidity to the cold dissection method. Its use is associated with a significant decrease in both surgical time and blood loss compared with the cold dissection method. 相似文献

Postoperative tonsillectomy pain in pediatric patients: electrocautery (hot) vs cold dissection and snare tonsillectomy--a randomized trial 总被引:3,自引:0,他引:3
OBJECTIVE: To determine the effect of the method of tonsillectomy on postoperative pain in pediatric patients. DESIGN: Prospective, randomized, single-blind, controlled clinical trial. SETTING: A university pediatric hospital in Aberdeen, Scotland. PATIENTS: A volunteer sample of 54 children, aged 3 to 12 years, with recurrent tonsillitis or symptomatic adenotonsillar hypertrophy. Two patients withdrew consent. INTERVENTIONS: Twenty-six children underwent a nonelectrical (ie, cold) dissection tonsillectomy with cold steel instruments, 5 of whom also had adenoidectomy by curettage. Monopolar diathermy forceps were used for tonsillar bed hemostasis. Twenty-four children had electrocautery (ie, hot) dissection tonsillectomy, 7 of whom underwent adenoidectomy by curettage without a suction coagulator. MAIN OUTCOME MEASURES: Postoperative analgesic consumption, time to regain normal diet and activity levels, and complications. RESULTS: Patients who underwent hot dissection tonsillectomy showed no difference in time to first drink or analgesic use within the first 24 postoperative hours compared with children undergoing cold nonelectrical dissection tonsillectomy. The hot dissection tonsillectomy group took 7.5 (95% confidence interval [CI], 1-14.1) more doses of analgesics than the cold dissection group over the next 12 days (P<.05). The hot dissection tonsillectomy group took 2.5 more days than the cold dissection tonsillectomy group to regain normal diet (P<.05). Thirteen children (54%; 95% CI, 34-74) in the hot dissection tonsillectomy group and 6 (23%; 95% CI, 7-39) in the cold dissection tonsillectomy group sought outpatient care for throat pain, otalgia, poor diet, pyrexia, and/or bleeding (P<.05). Throat pain delayed in onset or of prolonged duration affected 9 children (38%; 95% CI, 19-57) in the hot dissection tonsillectomy group as opposed to 3 children (12%; 95% CI, 0-24) in the cold dissection tonsillectomy group (P<.05). CONCLUSION: Hot dissection tonsillectomy increases morbidity in pediatric patients in the recovery period following hospital discharge. 相似文献

The aim of the study was to compare a single surgeon’s post-tonsillectomy haemorrhage rates using cold steel dissection and
coblation tonsillectomy techniques. Retrospective study on patients, who underwent tonsillectomy at West Wales General Hospital
(WWGH) performed by a single surgeon from 2006 to 2010 employing both cold steel and coblation tonsillectomies. Data were
analysed using Mann–Whitney and Chi-squared tests. The nominated surgeon performed 239 tonsillectomies at WWGH from 2006 to
2010. 119 patients underwent cold steel dissection and 120 had coblation tonsillectomy. There was no demographic difference
between the two groups. There was no statistically significant difference in the length of hospital stay between the two groups
(median 1 day in each group). 6/119 (5.0%) patients in the cold steel group, and 7/120 (5.8%) in the coblation group had post-operative
bleeding (p = 1.00). The return to theatre rate for cold steel dissection was 1/119 (0.84%) and for coblation surgery was 1/120 (0.83%)
(p = 1.00). Among the first 60 cases of coblation tonsillectomies, 4 patients (6.6%) had post-operative haemorrhage and the
latter 60 cases had 3 patients (5%). There was no evidence of a difference in the overall post-operative bleeding between
those who had cold steel dissection and coblation tonsillectomies. These data suggest that higher post-operative haemorrhage
is not inherent to coblation tonsillectomy. 相似文献

OBJECTIVE: To determine whether an increase in the use of bipolar diathermy energy to perform a tonsillectomy is associated with an increase in postoperative pain and haemorrhage. STUDY DESIGN: Prospective study. SETTING: District General Hospital. METHODS: In all, 101 patients above the age of 13 years who underwent a tonsillectomy that involved the use of bipolar diathermy during the study period were included. The cumulative amount of diathermy energy used to perform each tonsillectomy was calculated with the help of a digital stop clock timing device connected to the diathermy foot-pedal. MAIN OUTCOME MEASURES: Postoperative pain scores and the incidence of secondary haemorrhage were recorded for each patient at four points in time following surgery, up to the tenth postoperative day. The haemorrhage rates were categorised into three groups (no bleeding, minor bleeding and major bleeding) according to severity. Associations between the diathermy energy used to perform each tonsillectomy and the corresponding postoperative pain scores and secondary bleeding rates were investigated. RESULTS: There was a statistically significant positive relationship between the total amount of bipolar diathermy energy used per tonsillectomy and the pain scores at all the four recorded points in time (r(s) = 0.44-0.72, P < 0.001). When the median energy consumption in the three groups (no bleeding, minor bleeding and major bleeding) were compared using the Kruskal-Wallis test, we found that there was limited evidence of a difference between the groups, but this was not statistically significant at the 5% level [H (2) = 5.374, P = 0.065, 99% CI 0.058-0.071]. CONCLUSIONS: Increased use of bipolar diathermy during the performance of a tonsillectomy is associated with a statistically significant increased amount of postoperative pain. The dose-response relationship between diathermy energy and postoperative bleeding is less clear. This suggests that there could be other important factors such as surgical instrument characteristics and degree of tonsillar adherence that have an additional influence and are therefore possible areas for future research. 相似文献
