低温等离子刀、超声刀及传统方式行扁桃体切除术的术后两年随访比较

目的 通过对低温等离子刀、超声刀及传统方式行扁桃体切除术的患者进行2年随访,探讨三种手术方式的术后疗效差异。 方法 对行上述三种手术方式的86例患者在扁桃体切除术后6个月、1年及2年进行随访,观察术后扁桃体残体大小及黏膜炎症情况,并使用自制问卷调查咽部症状及满意度等信息。 结果 术后1年及2年随访时,低温等离子刀组和传统组的扁桃体上极残体评分较超声刀组要低,而低温等离子刀组和超声刀组的扁桃体下极残体评分则较传统组要低;术后6个月随访时低温等离子刀组和超声刀组的咽干症状均较传统组明显;术后2年随访时低温等离子刀组和超声刀组的患者满意度较传统组更高,而且传统组患者的咽部异物感更为明显;以上差异均有统计学意义(P<0.05)。另外术后1年及2年随访时,三组患者的咽干症状、扁桃体窝黏膜慢性炎症程度、咽痛频率及术后下呼吸道感染发生次数均无统计学差异(P>0.05)。 结论 相较于传统方式而言,使用低温等离子刀切除扁桃体的患者术后扁桃体残体发生率低,除短期术后易发生咽干外,中长期咽部不适症状较轻,患者满意度较高。超声刀方式优点与低温等离子刀相近,但在术中要注意对扁桃体上极的处理,防止其残留。

Coblation versus unipolar electrocautery tonsillectomy: a prospective, randomized, single-blind study in adult patients

OBJECTIVES: To determine if the coblation tonsillectomy (subcapsular dissection) results in less postoperative pain, equivalent intraoperative blood loss, equivalent postoperative hemorrhage rates, and faster healing compared with tonsillectomy was performed using unipolar electrocautery in adult patients. STUDY DESIGN: The authors conducted a prospective clinical trial. METHODS: Forty-eight patients underwent tonsillectomy and were randomly assigned to have one tonsil removed with coblation and the other with unipolar electrocautery. Outcome measures included time to remove each tonsil, intraoperative blood loss, patient-reported pain, postoperative hemorrhage, and amount of healing 2 weeks after surgery. RESULTS: Mean time to remove a single tonsil with coblation and electrocautery was 8.22 minutes and 6.33 minutes, respectively (P = .011). Mean intraoperative blood loss for each technique was less than 10 mL. Postoperative pain was significantly less with coblation as compared with electrocautery: 18.6% less painful during the first week of recovery. Seventy percent of blinded patients identified the coblation side as less painful during the overall 14-day convalescent period. Postoperative hemorrhage rates (2.1% for coblation and 6.2% for electrocautery) were not significantly different. No difference in tonsillar fossa healing was observed between the two techniques 2 weeks after surgery. During nine of the 48 surgeries, wires on the tip of the coblation handpiece experienced thinning to the point of discontinuity while removing a single tonsil. CONCLUSIONS: Coblation subcapsular tonsillectomy was less painful than electrocautery tonsillectomy in this 48-patient group. On average, intraoperative blood loss was less than 10 mL for both techniques. Postoperative hemorrhage rates and the degree of tonsillar fossa healing were similar between the two techniques. The coblation handpiece experienced degradation of vital wires in 18% of cases necessitating the use of a second, new handpiece.

Coblation vs. Electrocautery Tonsillectomy: A Prospective Randomized Study Comparing Clinical Outcomes in Adolescents and Adults

Objectives

Coblation is operated in low temperature, so it is proposed that tonsillectomy with coblation involves less postoperative pain and allows accelerated healing of the tonsillar fossae compared with other methods involving heat driven processes. However, the results of the previous studies showed that the effect of coblation tonsillectomy has been equivocal in terms of postoperative pain and hemorrhage. Though, most of the previous studies which evaluated coblation tonsillectomy were performed in children. Recently, electrocautery tonsillectomy has been used most widely because of the reduced intraoperative blood loss and shorter operative time compared to other techniques. This prospective study compared intraoperative records and postoperative clinical outcomes in adolescents and adults following coblation and electrocautery tonsillectomies.

Methods

Eighty patients over 16 years of age with histories of recurrent tonsillitis were enrolled. The patients were randomly allocated into coblation (n=40) and electrocautery tonsillectomy groups (n=40). All operations were performed by one surgeon who was skilled in both surgical techniques. Intraoperative parameters and postoperative outcomes were checked.

Results

Postoperative pain and otalgia were not significantly different between the two groups; however, there was a tendency towards reduced pain and otalgia in the coblation group. More cotton balls for swabbing the operative field were used introoperatively in the electrocautery group (P=0.00). There was no significant difference in postoperative hemorrhage, wound healing, commencement of a regular diet, and foreign body sensation between the groups.

Conclusion

Only cotton use, which represented the amount of blood loss, was less in the coblation tonsillectomy group. Coblation tonsillectomy warrants further study with respect to the decreased postoperative pain and otalgia.     

两种扁桃体切除方法的临床观察

目的比较两种不同扁桃体切除及止血方法的优缺点。方法将诊治的90例扁桃体切除术患者随机分为等离子手术组（A组）和传统手术组（B组）,每组各45例,所有手术均由同一术者完成。等离子手术组用低温等离子法切除扁桃体并止血;传统手术组则采用常规扁桃体剥离并用双极电凝止血。记录切除双侧扁桃体所需时间和出血量;术后第1天起每日记录患者咽部疼痛评分情况,连续10 d;术后第10天观察并记录扁桃体窝内的白膜状况。结果A、B两组手术总时间分别为（18.0±1.6）min、（43.5±3.4）min,术中总出血量分别为（9.3±1.3）ml、（53.8±5.5）ml,两组间差异均具有统计学意义（P〈0.05）;两组患者术后1周内疼痛指数差异比较具有统计学意义（P〈0.05）,1周后疼痛指数比较差异无统计学意义（P〉0.05）;A、B两组术后出血发生病例数分别为3例、4例,出血发生率比较差异具有统计学意义（P〈0.05）,术后比较,A、B两组白膜与扁桃体窝面积比分别为（43.8±6.6）%、（40.5±5.1）%,两组之间差异无统计学意义,但等离子组白膜较为清洁。结论与传统扁桃体剥离法比较,低温等离子法切除扁桃体具有手术损伤小、术中出血少、术后疼痛轻、恢复好等优点,可作为扁桃体切除手术的首选。     

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.     

Coblation tonsillectomy versus dissection tonsillectomy: postoperative hemorrhage

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.
