[The role of tonsillectomy in the treatment of chronic tonsillitis]

The problem of chronic tonsillitis remains one of the urgent problems of modern otorhinolaryngology. The article discusses the statistics and complications of chronic tonsillitis, provides indications for tonsillectomy and its main complications.

OBJECTIVE

Generalization and systematization of data on the impact of surgical treatment on the quality of life of patients with chronic tonsillitis.

MATERIAL AND METHODS

Search for literary sources, carried out using the search engines of the RSCI, PubMed, Web of Science, and eLibrary.

RESULTS

A review of literature sources demonstrates a significant improvement in the quality of life of patients after tonsillectomy; however, data from some studies show a trend towards a decrease in the number of planned tonsillectomies and an associated increase in the detection of local purulent-septic complications.

Adult tonsillectomy: An evaluation of indications and complications

OBJECTIVE

This study aimed to evaluate current adult tonsillectomy indications along with risk factors associated with postoperative complications.

METHODS

In 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.

RESULTS

574 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.

CONCLUSION

Infectious 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.

Postoperative hemorrhage following coblation tonsillectomy with and without suture: A randomized study in Chinese adults

PURPOSE

Coblation tonsillectomy (TE) increases gradually in China. Hemorrhage is the main complication after tonsillectomy. The conclusions of the studies about suture after tonsillectomy are conflicting. To compare the post-tonsillectomy hemorrhage (PTH) rates in patients who underwent coblation with vs. without suture.

MATERIALS AND METHODS

This was a randomized controlled study of adult patients who underwent coblation TE at our hospital between 01/2017 and 08/2019. The patients were randomized to TE with or without suture. The primary endpoint was the secondary PTH. The secondary endpoints included the primary PTH, grade of PTH, and incidence of PTH within 4 weeks post-TE.

RESULTS

There were no differences between the two groups regarding sex, age, disease course, and BMI (all P > 0.05). The occurrence of secondary PTH was lower in the suture group compared with the non-suture group (2.8% vs. 7.7%, P = 0.016). Compared with non-suture group, the incidence of PTH within 4 weeks (2.8% vs. 10.6%, P = 0.009) and the PTH degree (P = 0.02) were all significantly lower in the suture group.

CONCLUSION

Intraoperative suture reduces the secondary PTH in adult patients who underwent coblation tonsillectomy. The incidence of PTH within 4 weeks, PTH degree and pain might all improved for intraoperative suture.

Does Ibuprofen Increase Bleed Risk for Pediatric Tonsillectomy?

OBJECTIVE

To evaluate risk factors for pediatric posttonsillectomy hemorrhage (PTH) and the need for transfusion using a national database.

STUDY DESIGN

Retrospective cohort study.

SETTING

The study was conducted using the Pediatric Health Information System (PHIS) database.

METHODS

Children ≤18 years who underwent tonsillectomy with or without adenoidectomy (T±A) between 2004 and 2015 were included. We evaluated the risk of PTH requiring cauterization according to patient demographics, comorbidities, indication for surgery, medications, year of surgery, and geographic region.

RESULTS

Of the 551,137 PHIS patients who underwent T±A, 8735 patients (1.58%) experienced a PTH. The risk of PTH increased from 1.33% (95% confidence interval [CI]: 1.15%, 1.53%) in 2010 to 1.91% (95% CI: 1.64%, 2.24%) in 2015 (P < .001). Older age (≥12 vs <5 years old: adjusted odds ratio [aOR] 3.17; 95% CI: 2.86, 3.52), male sex (aOR 1.11; 95% CI: 1.05, 1.17), medical comorbidities (aOR 1.18; 95% CI: 1.08, 1.29), recurrent tonsillitis (aOR 1.15; 95% CI: 1.07, 1.24), and intensive care unit admission (aOR 1.74; 95% CI: 1.55, 1.95) were significantly associated with an increased risk of PTH. Use of ibuprofen (aOR 1.36; 95% CI: 1.22, 1.52), ketorolac (aOR 1.39; 95% CI: 1.14, 1.69), anticonvulsant (aOR 1.23; 95% CI: 1.03, 1.76), and antidepressants (aOR 1.35; 95% CI: 1.03, 1.76) were also associated with an increased risk of PTH. The need for blood transfusion was 2.1% (181/8735).

CONCLUSION

The incidence of PTH increased significantly between 2011 and 2015, and ibuprofen appears to be one contributing factor. Given the benefits of ibuprofen, it is unclear whether this increased risk warrants a change in practice.

Bleeding Complications After Transoral Robotic Surgery: A Meta-Analysis and Systematic Review

OBJECTIVE

Postoperative hemorrhage is the most common complication of transoral robotic surgery (TORS), the severity of which can range from minor bleeding treated with observation to catastrophic hemorrhage leading to death. To date, little is known about the incidence, risk factors, and management of post-TORS hemorrhage.

STUDY DESIGN

Systematic Review and Metanlysis.

METHODS

A systematic review of the published literature using the Cochrane Handbook for Systematic Reviews of Interventions was performed and examined TORS, postoperative hemorrhage, and the use of prophylactic transcervical arterial ligation (TAL).

RESULTS

A total of 13 articles were included in the analysis. To date, there have been 332 cases of hemorrhage following a total of 5748 TORS. The pooled median post-TORS hemorrhage rate was 6.47%. The overall incidence of minor and major hemorrhage was 5.29% and 2.90%. Patients with prior radiation (relative risk [RR] = 1.46, 95% confidence interval [CI] = 1.00-2.12), large tumors (RR = 2.11, 95% CI = 1.48-2.99), and those requiring perioperative coagulation (RR = 2.25, 95% CI = 1.54-3.28) had significantly higher relative risks of hemorrhage. There was no significant difference in the relative risk of overall hemorrhage with TAL. Looking at major hemorrhage, patients undergoing TAL had a large but insignificant relative risk reduction in post-TORS hemorrhage (RR = 0.40, 95% CI = 0.15-1.07).

CONCLUSION

The incidence of post-TORS hemorrhage is low (5.78%), and for major hemorrhage requiring emergent embolization, TAL, or tracheotomy to control hemorrhage it is even lower (2.90%). Large tumors, perioperative anticoagulation, and prior radiation were associated with significantly increased risk of post-TORS hemorrhage. TAL does not reduce the overall incidence of post-TORS hemorrhage but may lead to fewer severe hemorrhages.

Postoperative Bleeding Associated with Ibuprofen Use after Tonsillectomy: A Meta-analysis

Objective

To better quantify the risk of ibuprofen-associated posttonsillectomy hemorrhage (PTH).

Data Sources

PUBMED/MEDLINE, Web of Science, and Cochrane Clinical Trials Database.

Review Method

Literature searches were performed for English-language publications containing the terms tonsillectomy, ibuprofen, and tonsillectomy from database inception to May 2017. Human clinical trials, prospective cohort studies, and retrospective cohort studies related to tonsillectomy, ibuprofen use, and posttonsillectomy hemorrhage among pediatric patients were selected. Electronic searches revealed 151 studies, of which 12 were deemed eligible for analysis. Studies were weighted according to level of evidence and risk of bias.

Results

Pooling of results across all studies showed a statistically significant increase in PTH among the patients taking ibuprofen (odds ratio, 1.38; 95% confidence interval, 1.11-1.72). The I 2 statistic of 20.8% demonstrates overall low study heterogeneity and good comparability of the results.

Conclusion

Our meta-analysis of available cohort studies and randomized controlled trials (RCTs) shows possible increased tendency to PTH with the use of ibuprofen. This has not been demonstrated in other studies and systematic reviews because their analyses were limited by use of multiple nonsteroidal anti-inflammatory drugs and inclusion of studies limited to the perioperative period and low sample size. However, the current analysis is limited due to inclusion of many retrospective cohort studies with unclear follow-up and no blinding. Further RCTs will be required to investigate this trend toward increased PTH.

Tantum verde mouthwash for tonsillectomy: A prospective, double-blind, randomized control trial

OBJECTIVES

Post-tonsillectomy pain control is still considered a challenge. Topical agents would seem to be an ideal, safe option. Our objective was to compare the efficacy of mouthwash preparation with anti-inflammatory, anesthetic, and analgesic properties (Tantum Verde^®, 0.15% benzydamine hydrochloride) with that of placebo in improving post-tonsillectomy morbidity.

METHODS

A prospective, double blind, randomized clinical trial was performed. Patients older than 12-years-of-age who underwent tonsillectomy were recruited. Participants were randomized into 2 groups to receive either 0.15% benzydamine hydrochloride (TV) mouthwash solution (study arm) or a placebo solution. They were instructed to gargle the intervention they received 3 times a day for 7 days following surgery. Primary outcomes were intensity and duration of post-operative pain (using VAS visual analogue score) during a 2-week follow-up period. Secondary outcomes were pain medication demand, readmission, incidence of post-operative bleeding, hospital stay duration, and time to resume normal solid diet.

RESULTS

Thirty-nine patients completed the study, of whom 23 received TV and 16 received placebo. The mean age was 23.1 years. There was no significant difference between the groups in the primary or secondary outcomes.

CONCLUSIONS

The data suggest that topical treatment with TV mouthwash solution was not found to be superior to placebo in the management of post-tonsillectomy pain, bleeding, and return to a regular solid diet. Further research studies should be designed to investigate the ideal treatment for reducing post-tonsillectomy morbidity.

Postoperative hemorrhage following tonsillectomy in adults: Analysis of population-based inpatient cohort in Taiwan

OBJECTIVE

Because of the lack of population-based analyses, this study elucidated the epidemiology and 30-day postoperative complications of inpatient adult tonsillectomies in Taiwan.

METHODS

Using the Taiwan National Health Insurance Research Database, we identified all inpatient adult tonsillectomies (age>20years) in Taiwan during 1997-2012 through International Codes of Diseases, 9th Revision. Trend of the inpatient tonsillectomy in adult during the study period was explored. Major complications of readmission, reoperation, and mortality within 30days after tonsillectomies were identified. Factors associated with major complications were analyzed using multivariate logistic model.

RESULTS

In total, 27,365 adults received inpatient tonsillectomies (mean age, 38.4±13.0years; 57.2% male). The overall incidence was 10.2 per 100,000 population per year among adults. Incidence rates increased from 1997 (8.2/100,000 adults) to 2012 (11.2/100,000 adults) (P trend<0.001). The rate of readmission for any reason, readmission for bleeding, reoperation for bleeding, and mortality were 4.9%, 2.2%, 1%, and 0.1%, respectively. Young age increased the risk of bleeding-related readmission and reoperation, whereas old age increased the risk of readmission for any reason and mortality. Male gender increased the risk of all major complications. Hypertension was associated with an increased risk of bleeding-related readmission (odds ratio [OR]=2.21; 95% confidence interval [CI] 1.68-2.92) and reoperation (OR=2.17; 95% CI 1.44-3.27). Existing catastrophic illness increased the risk of readmission (OR=4.28; 95% CI 3.60-5.08) for any reason and mortality (OR=3.24; 95% CI 1.37-7.65). Nonsteroidal anti-inflammatory drugs and steroids were associated with an increased risk of readmission or reoperation for bleeding.

CONCLUSION

Incidence rates of inpatient adult tonsillectomy increased during 1997-2012 in Taiwan. Age, gender, comorbidity, and drug administration characteristics were associated with major complications of adult tonsillectomies in this cohort.

Effect of Suturation Plus Surgicel Application on Post-Tonsillectomy Bleeding and Pain

OBJECTIVE

The aim of this study was to evaluate the effect of suturation (tonsillary fossa closure) plus Surgicel application on postoperative bleeding and pain after tonsillectomies performed using a classical dissection method.

STUDY DESIGN

A prospective, randomized, double-blind, clinical trial was performed on 760 patients undergoing tonsillectomy or adenotonsillectomy during a 5-year period.

METHODS

After excluding patients with hemorrhagic disorder, chronic disease, and peritonsillar abscess, both tonsils were removed via classic dissection technique (cold knife or blunt dissection) and then electrocauterized for hemostasis. The tonsillar fossa randomly assigned to the treatment protocol (Group 1) was closed by sutures, following Surgicel application. The other side was unaltered and acted as the control (Group 2). Pain was evaluated every day for 10 days postoperatively, and bleeding was reported at any time.

RESULTS

A total of 760 patients (393 males, 367 females) between the ages of 4 and 35 years (mean age 13.46 ± 7.98) were included in the study. Bleeding was observed in 31 patients: 8 from Group 1; and 23 from Group 2 (95% confidence interval [CI], P < 0.05). The average pain score was greater in Group 1 than in Group 2 on each postoperative day (95% CI, P < 0.05).

CONCLUSION

Suturation plus Surgicel application increased pain levels while decreasing bleeding incidence during the postoperative period.

Nationwide readmissions after tonsillectomy among pediatric patients - United States

OBJECTIVES

1) Investigate incidence and predictors of readmissions after tonsillectomy with or without adenoidectomy (T&A) in children. 2) Identify factors that may predict readmission.

SETTINGS

Nationwide cross-sectional survey of US hospital admissions.

SUBJECTS

and Methods: The 2013 Nationwide Readmission Database (NRD) was used to examine all-cause readmissions within 30 days of T&A in children (age <18 years). Logistic regression was used to analyze the associations of demographics, diagnosis, insurance status, length of index stay, and median household income with readmission.

RESULTS

9079 children undergoing T&A resulted in 327 (3.6%) patients requiring readmission. The average age of children readmitted were 5.0 years and they were 51% female. The most common readmission diagnoses were dehydration (47%), hemorrhage (26%), and pain (16%). The average time to readmission was 7.3 days. The average times to readmission for hemorrhage, pain and dehydration were 6.3, 4.5 and 4.1 days, respectively. Children who needed respiratory intubation (OR = 4.0), had a medical or surgical complication (OR = 3.3), or prolonged hospital stay (OR = 1.03) during the index admission were more likely to be readmitted. Age, gender, payer and socioeconomic status and diagnosis of obstructive sleep apnea (OSA) did not increase the odds of readmission.

CONCLUSIONS

Readmissions in children after T&A were primarily due to dehydration, hemorrhage, and pain. Adequate symptom control in children has the greatest potential to reduce readmission rates following T&A.

Lower-pole intracapsular tonsillectomy in obstructive sleep apnea patients

CONCLUSION

Lower-pole intracapsular tonsillectomy (LPIT) is a valuable surgical technique capable of decreasing post-operative bleeding in obstructive sleep apnea (OSA) patients.

OBJECTIVE

This study performed LPIT to simultaneously reduce post-operative bleeding of lower pole and prevent recurrent tonsillitis of upper pole and compared its effects to extracapsular tonsillectomy (ET).

METHODS

ET was performed in the extracapsular plane, with complete monopolar dissection. In LPIT, the upper pole of palatine tonsil was removed by electrocautery with the extracapsular plane, followed by removal of the lower-pole by plasma ablation with the intracapsular plane. Post-operative bleeding incidence, bleeding site, and degree of pain were compared between the two groups.

RESULTS

Three hundred and forty-seven patients diagnosed of OSA with polysomnography were enrolled. ET was performed in 152 patients and LPIT in 195 patients. There were no significant differences in post-operative pain between the two groups. The LPIT group showed significantly lower total bleeding incidence than the ET group (4.1% vs 9.2%; p = .05). In particular, lower-pole bleeding incidence was lower in the LPIT group than the ET group (1.0% vs 5.3%; p = .02).

Increased immediate postoperative hemorrhage in older and obese children after outpatient tonsillectomy

INTRODUCTION

Postoperative hemorrhage is one of the serious complications of adenotonsillar surgery. This study seeks to investigate the relationship between post-tonsillectomy/adenotonsillectomy hemorrhage in the pediatric population and obesity, obstructive sleep apnea (OSA), adenotonsillar hypertrophy (ATH), chronic tonsillitis (CT), and peritonsillar abscess (PTA) in the immediate post-operative setting.

METHODS

The California Ambulatory Surgery Data for the years 2005-2011 were reviewed. The records of patients aged less than 18 years undergoing tonsillectomy (T) or adenotonsillectomy (AT) were extracted using relevant ICD-9 diagnosis codes. The association between hemorrhage and obesity, OSA, AH, CT, PTA, and patients' demographics among surgeries performed in the outpatient setting was evaluated.

RESULTS

A total of 138,998 procedures, 22,478 Ts and 116,520 ATs, were performed during 2005-2011, of which 3.0% were performed on obese children. Hemorrhage occurred in 156 cases (0.1%), and was associated with an age from 9 to 18 years (p=0.01), and obesity (p=0.02). There was no association between hemorrhage and gender (p=0.8), OSA (p=0.6), ATH (p=0.5), CT (p=0.35), PTA (p=0.47), or T versus AT (p=0.3). Multivariate analysis revealed that hemorrhage was about 2.3 times more likely to occur in obese children (odds ratio [OR]=2.3; 95% Confidence Interval: 1.1-5.1; p=0.03).

CONCLUSIONS

Obesity and older age are associated with an increased risk of immediate post-operative hemorrhage following tonsillectomy with or without adenoidectomy in the outpatient setting. Gender, OSA, ATH, CT, PTA, and T versus AT did not alter the risk of post-operative hemorrhage.

Safety and efficacy of pre-incisional peritonsillar lornoxicam in paediatric post-tonsillectomy pain: a prospective double-blind, placebo-controlled, split-body clinical study

OBJECTIVES

To evaluate the risk of peri-operative bleeding and re-intervention with peritonsillar lornoxicam infiltration in paediatric tonsillectomy.

DESIGN

Prospective, randomised, double-blinded, placebo-controlled, split-body study.

SETTING

University hospital.

PARTICIPANTS

A total of 68 patients (7-15 years), ASA I-II, scheduled for tonsillectomy divided into two groups (n = 34) to receive bilateral peritonsillar saline infiltration (placebo group) or peritonsillar saline infiltration in one tonsil (placebo side) and 8 mg lornoxicam in the other tonsil (intervention side; study group). Drugs were administered after induction of anaesthesia and before start of surgery.

MAIN OUTCOME MEASURES

Intra-operative and postoperative bleeding score, platelet aggregometry before and 30 min after study drug administration, the verbal rating pain scale, time to first postoperative analgesic request, total analgesic consumption during 1st 24 h postoperative and adverse effects were evaluated.

RESULTS

The difference in bleeding score between groups did not reach our definition of statistical significance (P < 0.05). Platelet aggregometry tests did not change significantly with time between groups. Lower postoperative pain scores, longer time to first analgesic request (372.76 ± 82.15 versus 64.89 ± 25.76 min P < 0.001) and lower paracetamol consumption (421.76 ± 125.63 versus 690.29 ± 141.47 mg, P < 0.001) were recorded in study group compared with control group. No patient required hospital re-admission or re-operation because of postoperative tonsillar bed bleeding.

CONCLUSIONS

The lack of significant complications suggests that pre-incisional peritonsillar lornoxicam followed by intravenous paracetamol rescue analgesia may be safe for tonsillectomy in children. To avoid conflict with intra-operative bleeding, postoperative infiltration of lornoxicam is recommended.

Microdebrider-assisted intracapsular tonsillectomy in adults with chronic or recurrent tonsillitis

OBJECTIVES/HYPOTHESIS

We compared the effectiveness and morbidity of microdebrider-assisted total intracapsular tonsillectomy (ICTE) with conventional extracapsular tonsillectomy (ECTE) in adults with chronic or recurrent tonsillitis.

STUDY DESIGN

Prospective randomized surgical trial.

METHODS

Adult patients with recurrent or chronic tonsillitis who underwent tonsillectomy between July 2010 and July 2012 in the Department of Otorhinolaryngology-Head and Neck Surgery, Medical University Innsbruck, Innsbruck, Austria, were consecutively included. Patients were randomized to receive either ICTE or ECTE. Patients and examiners were blinded to the surgical procedure. Effectiveness was assessed with the Tonsil and Adenoid Health Status Instrument (TAHSI). Various parameters of perioperative morbidity and the occurrence of tonsillar remnants were recorded.

RESULTS

In the 104 randomized patients, the average TAHSI score was 34.6 ± 11.7 before and 2.2 ± 5.7 after 6 months following tonsillectomy (P < 0.001). TAHSI scores improved equally in patients receiving conventional ECTE (33.6 points; 95% confidence interval (CI), 29.5 to 37.6) and in patients with ICTE (31.8 points; 95% CI, 27.7 to 35.9; between groups P = 0.6). Posttonsillectomy hemorrhage was more frequent following conventional ECTE (P = 0.03). Following ECTE, patients required more pain medication then following ICTE (P < 0.05). Tonsillar remnants were significantly more frequent after ICTE (P < 0,001). However, presence of tonsillar remnants had no influence on postoperative THASI scores (P > 0.5).

CONCLUSION

Tonsillectomy reduced symptoms of chronic or recurrent tonsillitis in adults with remarkable effectiveness. Microdebrider-assisted ICTE reduced symptoms as effectively as conventional ECTE. ICTE was associated with lower morbidity, but residual tonsils occurred in almost half of patients, costs were higher, and the intracapsular approach was more intricate and time-consuming.

Healthcare disparities in revisits for complications after adult tonsillectomy

OBJECTIVE

Determine if disparities exist for revisit complications after adult tonsillectomy.

METHODS

Cases of adult tonsillectomy were extracted from the state ambulatory surgery databases and linked to the state emergency department databases and inpatient databases for California, Iowa, Florida and New York for 2010 and 2011. Revisits within 14days for diagnoses of: post-tonsillectomy bleeding, acute pain and nausea/vomiting/dehydration were determined and analyzed for associations of these complications with age, sex, race, median household income and comorbidity score.

RESULTS

Among 17,836 tonsillectomies (63.7% female; mean age, 29.0years), revisit rates for post-tonsillectomy bleeding, acute pain and fever/dehydration were 5.1, 2.8 and 1.5%, respectively. On multivariate analysis, only female sex was associated with a lower post-tonsillectomy bleeding rate (odds, 0.48, p<0.001). Decreasing household income, female sex, black and Hispanic race were associated with increased revisits for acute pain (odds, 1.21, 1.49, 2.03 and 1.32, p≤0.002). Female sex was associated with an increased odds of a revisit for FNVD (odds, 1.94, p<0.001).

CONCLUSIONS

Significant disparities with respect to income and race exist in the incidence of revisits and potentially avoidable complications after adult tonsillectomy.

The use of 3 sugammadex out of 5 reversal of during recovery of rocuronium-induced neuromuscular blockade in a patient with post-tonsillectomy hemorrhage: a case report

Post-tonsillectomy hemorrhage (PTH) is the most frequent complication of tonsillectomy, and occasionally results in a lethal outcome. A 21-year-old man (height 180 cm, weight 95 kg) was scheduled for a bilateral tonsillectomy and uvulopalatopharyngoplasty for treatment of obstructive sleep apnea. He required 5 rounds of general anesthesia due to recurrent PTH. The anesthesiologist used sugammadex a total of 3 times to achieve the successful reversal of the deep neuromuscular blockade (NMB) induced by rocuronium. After sugammadex 2 mg/kg was administered, the NMB was reversed in 2 minutes each time. Re-administration of rocuronium within a short time interval after sugammadex may result in unpredictable effects of neuromuscular blocking agents. Sugammadex made it possible to perform a rapid, complete reverse when the residual block was maintained by an incomplete reversal of anticholinesterase.

The effect of paracetamol, metamizole sodium and ibuprofen on postoperative hemorrhage following pediatric tonsillectomy

OBJECTIVE

To determine the risk of postoperative hemorrhage associated with the use of analgesic drugs including paracetamol, metamizole sodium and ibuprofen after pediatric tonsillectomy.

PATIENTS AND METHODS

Three hundred and forty consecutive children with recurrent tonsillitis and/or obstructive symptoms were included in the study. Children were divided into three groups based on the drugs used for postoperative pain relief. Each group received paracetamol, metamizole sodium and ibuprofen following the surgery. The study of population was compared respect to postoperative bleeding. Chi-square test was used for statistical analysis.

RESULTS

A total of 115 patients received ibuprofen, 115 patients were given metamizole sodium and 110 patients were given paracetamol. Posttonsillectomy hemorrhage occurred in fourteen (4.11%) children, consisting of primary hemorrhage in two patients and secondary hemorrhage in twelve patients. While 6 of 115 children (5.21%) who were given ibuprofen had postoperative hemorrhage, 4 of 115 children (3.47%) in metamizole sodium group and 4 of 110 patients (3.63%) in paracetamol group had hemorrhage. There was no significant difference with respect to hemorrhage rates between these three groups (p<0.05).

CONCLUSION

In our study we could not show significant risk of hemorrhage after using of ibuprofen, metamizole sodium and paracetamol administration and they can be used safely for posttonsillectomy pain.

Post-tonsillectomy bleeding: How much is too much?

Complication rates become important in discussions for informed surgical consent and for quality assurance purposes. In an attempt to quantify literature-based rates for post-tonsillectomy bleeding, a MEDLINE search was carried out. Of 4,610 papers 63 reported post-tonsillectomy bleeding rates. The weighted mean, standard deviation and 95% confidence intervals were calculated for those papers. The mean (4.5%) plus 2 standard deviations (9.4%) suggests a maximum “expected” sustained bleeding rate of 13.9%. In the literature, which should reflect optimum results, there were 3 reports of bleed rates in the 18-20% range. These data may be useful for quality assurance committees and individual clinicians.

Adult tonsillectomy and day care surgery

OBJECTIVE

To evaluate the safety of adult tonsillectomy as a day care surgery

METHODS

Records of 664 patients above the age of 12 years, who underwent tonsillectomy were analysed. These patients were operated in our department within January 1999 and September 2002. Only 13 patients (1.95%) had post operative bleeding and were readmitted after discharge. The data of these patients were collected from medical records as well from the morbidity meeting proceedings and was reviewed retrospectively. Statistical analysis was done by using 'one sample t-test'.

RESULTS

Overall incidence of post operative bleeding was 1.95%. None of our pateients bled with 12 hours of Surgery, 0.3% had bleeding between 12 to 24 hours after tonsillectomy and 1.65% encountered bleeding between 24 hours to the 6th post operative day. Bleeding was not major in majority of patients as only 0.45% of the patients required second anesthesia to control the bleeding and only 0.35% of patients required blood transfusion to replace the lost blood volume. In addition, higher incidence of bleeding was seen in males, in the older age group of 31-40 years, patients with obstructive sleep aponea and in patients where tonsillectomy was done by electrocautry dissection.

CONCLUSION

Based on these observations, we conclude that Adult tonsillectomy can be safely preformed in our setup.

Risiko von Blutungen nach Adenotomie und Tonsillektomie

BACKGROUND

Hemorrhage after tonsillectomy and adenoidectomy remains a serious complication. Therefore, routine preoperative coagulation screening, including activated partial thromboplastin time (aPTT), prothrombin time (PT) and platelet count (PLC), are regularly performed, also for medicolegal reasons. In the recently published statement of the German Society of Otorhinolaryngology, Head and Neck Surgery the need for routine preoperative coagulation screening is discussed, but so far no standardized procedure had been established. According to this statement - at least for children - routine preoperative coagulation screening is not mandatory as long as the thorough medical history provides no evidence for a coagulation disorder ( http://www.hno.org/kollegen/gerinnung_te_ae.html ). The present study was undertaken to determine the occurrence of postoperative hemorrhage on the one hand, and the incidence of abnormal preoperative routine coagulation parameters or pathological anamnesis findings on the other.

PATIENTS AND METHODS

In 688 patients, a standardized clinical history was obtained using a questionnaire. Coagulation screening included aPTT, PT, and PLC was also carried out. Bleeding complications were then correlated with anamnesis features and abnormalities in coagulation screening.

RESULTS

In 39 (5.7%) of the 688 patients we found abnormal coagulation values, which were confirmed in repeated analyses. In six of these a detailed analysis revealed occult coagulation disorders requiring correction only in the case of bleeding complications who were previously unknown. Fifteen patients were already known to have a coagulation disorder, and the anamnesis identified no additional patient at risk. Thus, 21 patients with coagulation disorders requiring correction in the case of a bleeding complication underwent surgery. However, only eight (38%) of these showed abnormal routine coagulation parameters. Surgical treatment of postoperative hemorrhage was required in 12 patients, all of whom had normal values for aPTT, PT and PLC.

CONCLUSION

The frequently performed determination of routine coagulation parameters (aPTT, PT, PLC) is not able to reliably identify relevant coagulation disorders or to predict the risk for postoperative hemorrhagic complications after adenoidectomy or tonsillectomy.

Is bacterial colonisation of the tonsillar fossa a factor in post-tonsillectomy haemorrhage?

Objectives:

To identify if there is a link between bacterial colonisation of the tonsillar fossa and post-tonsillectomy haemorrhage.

Study design and setting:

Prospective non-interventional study of 105 patients who underwent tonsillectomy during a seven-month period. The study took place in a secondary care centre, the West Middlesex University Hospital.

Participants:

The participants were 105 patients who consecutively underwent tonsillectomy. The exclusion criteria were any patients with suspected or known malignancy, or known bleeding dyscrasias. The participants underwent microbiological sampling of the tonsil pre-operatively.

Main outcomes measures:

The outcome measures were primary or secondary bleeding, defined as any evidence of haemorrhage in the tonsillar fossae.

Results:

Twenty-four per cent of patients undergoing tonsillectomy had positive cultures from their tonsils pre-operatively. Patients with bacterial colonisation of the tonsillar fossa pre-operatively had an increased rate of post-tonsillectomy haemorrhage (odds ratio: 3.8, 1.1–12.1, 95 per cent confidence intervals,p = 0.04).

Conclusion:

This prospective study has found a relationship between bacterial colonisation of the tonsillar fossa and post-tonsillectomy haemorrhage. This suggests that there may be an argument for the use of antibiotics in those cases with positive pre-operative cultures. In view of the types of pathogens isolated, we feel that the management of a post-tonsillectomy bleed should include a beta lactamase inhibiting antibiotic.

Hemorrhage risk after quinsy tonsillectomy

BACKGROUND

The goal of the study was to evaluate the incidence and possible predictive factors of post-tonsillectomy hemorrhage (PTH) in patients with peritonsillar abscess, treated by acute abscess tonsillectomy.

METHODS

A retrospective cohort study was performed on 205 patients who underwent bilateral abscess tonsillectomy under general anesthesia. Age, sex, smoking habits, history of recurrent tonsillitis or prior peritonsillar abscess, current medical treatment, side of the peritonsillar abscess, initial treatment, surgeon's experience, procedure duration, intra- and postoperative anti-inflammatory medications, and side of bleeding were analyzed.

RESULTS

Bleeding occurred in 27 patients (13%). Ipsilateral hemorrhage was observed in 8 patients (4%) and contralateral hemorrhage in 19 patients (9%). The higher incidence of PTH in the side contralateral to the abscess was found to be statistically significant (P = 0.02). Male gender (P = 0.042), smoking (P = 0.009), and aspirin intake (P = 0.008) were statistically significant factors associated with an increased PTH risk.

CONCLUSION

The risk of bleeding following abscess tonsillectomy seems higher than reported in elective tonsillectomy. This high incidence is mainly due to patients with prior aspirin intake or to bleeding in the side contralateral to the abscess. Postoperative bleeding could be reduced by performing a unilateral acute abscess tonsillectomy in selected patients. An algorithm is proposed for the management of peritonsillar abscess based on age, prior history of pharyngo-tonsillar infections, aspirin intake, and clinical improvement after initial drainage and antibiotherapy.

Postoperative Tonsillectomy Bleed: Coblation Versus Noncoblation

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.

Post tonsillectomy morbidity: following the introduction of single-use-instruments

OBJECTIVE

Following the introduction of single-use-instruments (SUI) for tonsillectomy in January 2001 in UK, the Medical Devices Agency (MDA) received reports of significant increase in secondary haemorrhage in some centres. This was believed to be related to electrosurgical (diathermy) forceps. The aim of this study is to compare post tonsillectomy morbidity before (year 2000) and after (year 2001) the introduction of SUI in a unit where bipolar dissection is the most popular method of dissection.

METHOD

The case notes of all tonsillectomy patients between 20 April and 31 October for the years 2000 (145 patients) and 2001 (166 patients) were reviewed. The patients' age and sex, other concurrent operations, grade of surgeon, dissection and haemostasis methods, length of post operative hospital stay and the reason for prolonged stay (if more than one night) were noted. Readmitted cases were analysed to identify the cause and the management.

RESULTS

There was no case of reactionary haemorrhage in both the non SUI (year 2000) and the SUI (year 2001) groups. For the non SUI versus SUI group, 6.2 versus 4.8% stayed more than one night post operatively; 4.8 versus 5.4% were readmitted for secondary haemorrhage with 1.4 versus 2.4% return to theatre to control bleeding, respectively. The average hospital stay for the readmitted cases were 2.1 versus 1.6 days and the average time lapse between tonsillectomy and secondary haemorrhage were 6.7 versus 6 days respectively.

CONCLUSION

There was no significant difference in post tonsillectomy morbidity following the introduction of SUI.
