Combined mitomycin C application and free flap conjunctival autograft in pterygium surgery

PURPOSE: To evaluate the long-term postoperative outcome and complication rate of combined intraoperative low-dose mitomycin C application and free conjunctival autograft for the treatment of pterygium. METHODS: In a prospective, consecutive, noncomparative case series, a series of 46 consecutive patients (50 eyes) with primary pterygium (43 eyes) or recurrent pterygium (7 eyes) were studied. The patients' ages ranged from 23.0 to 80.0 years (mean, 53.4 years). All patients underwent pterygium excision combined with intraoperative low-dose mitomycin C application (0.02% for 2 minutes) and free conjunctival autograft. The mean follow-up period was 29.2 months (range 12 to 41 months). The main outcome measures were recurrence of pterygium and postoperative complications. RESULTS: Pterygium recurred to a small extent (0.5 mm) in one eye (2%) of a patient with recurrent pterygium. There were no intraoperative complications. Subconjunctival graft hematoma appeared soon after surgery and resolved spontaneously in five eyes (10%). One eye developed transient high intraocular pressure without optic nerve or visual field defect, and one eye developed mild symblepharon. There were no sight-threatening complications or serious side effects. CONCLUSIONS: By applying a single low dose of mitomycin C combined with free conjunctival autograft during pterygium excision, the recurrence rate of pterygium can be markedly reduced.

Clinical outcome study of a modified surgical technique for pterygium excision

BACKGROUND: Pterygium is a common condition that has many and varied surgical management techniques. Our aim was to describe and evaluate the safety and efficacy of a modified tissue-sparing surgical procedure for management of pterygium. METHODS: This was a retrospective, clinical outcome study of 67 consecutive pterygium head excisions and mini inferior conjunctival autografts (PHEMICA), performed by a single senior surgeon over 7 years. The technique evaluated was a modified pterygium head removal and inferior conjunctival autograft, maximising host tissue preservation. RESULTS: Group A (primary pterygia): 5.25% recurrence rate (3 of 57 eyes). Group B (recurrent pterygia): 30% recurrence rate (3 of 10 eyes). No major complications occurred. One partial autograft necrosis was noted (1.5%, 1 of 67 eyes), with full resolution. INTERPRETATION: The described technique is fast, safe, and effective with a 5.25% recurrence rate in those with primary pterygia. It is not, however, recommended in the treatment of recurrent pterygia; this group of patients requires a more radical excision with a larger autograft and the use of adjuncts such as mitomycin C.     

带蒂结膜瓣移植联合MMC治疗翼状胬肉合并结膜松弛症

目的：探讨带蒂结膜瓣移植联合丝裂霉素治疗翼状胬肉合并结膜松弛症的疗效。 方法：对翼状胬肉合并结膜松弛症患者122例156眼进行翼状胬肉切除,下方带蒂结膜瓣移植联合术中使用0.2g/L丝裂霉素C。 结果：患者122例156眼术后2mo眼部症状有不同程度改善。泪河恢复正常者136眼（87.18％）;泪膜破裂时间（BUT）≥10s者117眼（75.00％）;裂隙灯显微镜检查眼球与下睑缘、内外眦部之间无松弛结膜皱褶者147眼（94.23%）;下睑缘位置正常者142眼（91.03%）。手术后观察6mo~4a,胬肉复发5眼（3.21%）,结膜松弛复发15眼（9.62%）。 结论：翼状胬肉切除术中,下方带蒂结膜瓣移植联合术中使用丝裂霉素C治疗翼状胬肉合并结膜松弛症,手术简单易行,取材容易,安全可靠,损伤小,并发症少,复发率低,适合临床开展。     

Low-dose intraoperative mitomycin C as chemoadjuvant for pterygium surgery

PURPOSE: To evaluate the efficacy and safety of low-dose intraoperative mitomycin C (MMC) during bare sclera procedure and to compare the rates of pterygium recurrence between recurrent pterygium patients treated with adjuvant MMC and those reconstructed with a conjunctival autograft. METHODS: We studied the recurrence of pterygium, 12-month pterygium-free survival rates, final appearance, and postoperative complications in 96 eyes of 92 patients who received either intraoperative 0.02% MMC for 30 seconds or conjunctival autografting after pterygium excision. Patients were divided into three groups: group 1 included 38 eyes with primary pterygium undergone intraoperative MMC; group 2, 26 eyes with recurrent pterygium treated with intraoperative MMC; and group 3, 32 eyes with recurrent pterygium treated with pterygium excision and conjunctival autografting. RESULTS: Pterygium recurred in 3 (7.9%) of 38 eyes in group 1, 5 (19.2%) of 26 eyes in group 2, and 2 (6.3%) of 32 eyes in group 3. Despite the higher recurrence rate in group 2 compared with that of group 3, the difference between the two was not statistically significant (p = 0.22). The cumulative probabilities of success were 91.6+/-4.6%, 80.8+/-7.7%, and 92.3+/-5.4% at 12 months for groups 1, 2, and 3, respectively. Final appearance of the pterygium excision area was satisfactory in nearly two-thirds of the MMC-treated patients, 71.1% and 65.4% for groups I and 2, compared to 75.1% of patients who had undergone conjunctival autografting. No patients experienced severe complications during a mean postoperative follow-up of 27.3+/-4.1 months, 29.9+/-3.9 months, and 40.9+/-19.1 months for groups 1, 2, and 3, respectively. CONCLUSIONS: A single intraoperative application of 0.02% MMC for 30 seconds after pterygium excision is associated with minimal complication and effectively reduces the recurrence rates after excision of primary or recurrent pterygium. In comparison with conjunctival autografting, low-dose application of MMC after bare sclera procedure is less efficacious in preventing recurrence of pterygium, but simpler and produces a similar proportion of patients with satisfactory final appearance.

Intraoperative mitomycin C versus autologous conjunctival autograft in surgery of primary pterygium with four‐year follow‐up

Purpose: To compare the 4‐year outcome of primary pterygium excision using intraoperative mitomycin C (MMC) with suturing a free conjunctival autograft (CA). Methods: A total of 115 eyes with nasal primary pterygium of 115 patients were included in the study. After randomization into two groups, the eyes were operated on by a single surgeon (GK). After excision of the pterygium, 56 eyes received 0.04% MMC intraoperatively on the bare sclera for 3 min and 59 eyes received a free CA sutured using 7‐0 Vicryl. Postoperative follow‐up was 4 years. Main outcome measures were recurrences, re‐operations, surgery time, complications, visual acuity and astigmatism. Statistical evaluation was performed with the chi‐squared test. Results: The recurrence rate was 38% in the MMC group and 15% in the CA group (p < 0.05). The re‐operation rate of the recurrences was 53% in the MMC group and 29% in the CA group. Average surgery time was 13 minutes (range: 6–22 min) in the MMC group and 26 min (range: 18–32 min) in the CA group (p < 0.01). There was no significant change in best‐corrected visual acuity and astigmatism. One major complication occurred in each group. The most frequently observed complication was delayed epithelial healing (40%) and mild scleral thinning (20%) in the MMC group and suture‐related inflammation in the CA group (10%). Conclusion: Pterygium surgery including free autologous conjunctival grafting is associated with fewer recurrences, re‐operations and complications than using the bare sclera technique together with single‐dose intraoperative MMC.     

Pterygium surgery by double-sliding flaps procedure: Comparison between primary and recurrent pterygia

Purpose:This study aimed to evaluate the surgical outcomes of pterygial excision for primary and recurrent pterygia by a single method of pterygia excision combined with two conjunctival flaps.Methods:This retrospective study divided 193 cases of pterygium into the primary (140 cases) and recurrent (53 cases) pterygium groups. Following double-sliding conjunctival transposition flap operation and surgical excision of the pterygium, the success and recurrence rates of pterygial surgery were assessed based on visual acuity and corneal and total astigmatism during follow-up at least 6 months.Results:Both primary and recurrent pterygium groups showed significant improvements in visual acuity and astigmatism (corneal and total) between before and after this procedure. Total astigmatism and success rate of primary pterygium were significantly better than those for recurrent pterygium. Two cases (1.4%) of primary pterygium and four cases (7.5%) of recurrent pterygium developed recurrence, corresponding to a rate of 3.1% (6/193 cases). The success rates significantly make a difference between primary and recurrent groups but did not differ significantly between the first recurrent and over twice recurrent pterygium. However, visual acuity, cornea, and total astigmatism improved significantly after surgery in first recurrent group but not in over twice recurrent group.Conclusion:The double-sliding conjunctival flaps surgery appeared to be a useful method, with a better success rate and lower pterygial recurrence in pterygium surgery. Especially, when pterygium is larger or recurrent type, this technique can be easily covered the bare sclera, as compared to any transposition conjunctival flap operation.

A comparative study of recurrent pterygium surgery: limbal conjunctival autograft transplantation versus mitomycin C with conjunctival flap

OBJECTIVE: To compare the recurrence rate following treatment of recurrent pterygia using one of two techniques-limbal conjunctival autograft transplantation versus low-dose intraoperative mitomycin C (0.2 mg/ml) combined with conjunctival flap closure. DESIGN: Randomized clinical trial. PARTICIPANTS: Eighty-one patients with recurrent pterygia treated by limbal conjunctival autograft transplantation (n= 41) or mitomycin C combined with conjunctival flap (n= 40) participated. INTERVENTION: Limbal conjunctival autograft transplantation or low-dose intraoperative mitomycin C application with conjunctival flap technique was performed on recurrent pterygium cases. MAIN OUTCOME MEASURES: Recurrence of pterygium and postoperative complications. RESULTS: During mean follow-up periods of 16+/-1.9 and 15.5+/-1.5 months, six recurrences (14.6%) in the limbal conjunctival autograft transplantation group and five recurrences (12.5%) in the mitomycin C group were observed (P=0.77). The difference between the mean ages of recurrent (26.4+/-8.0 years) and nonrecurrent (35.8+/-11.9 years) cases for all patients was statistically significant (P=0.014). Technically, limbal conjunctival autograft transplantation seemed to be more difficult. The most frequent complication in limbal conjunctival autograft transplantation was graft edema, whereas that in the mitomycin C group was superficial keratitis. CONCLUSION: Both techniques showed similar recurrence rates in the treatment of recurrent pterygia. Although technically easier to perform, further follow-up is necessary to determine the long-term safety of low-dose intraoperative mitomycin C with conjunctival flap closure. The surgeon's familiarity with either procedure should determine the method of choice.     

逆向方法联合丝裂霉素结膜瓣转移术治疗翼状胬肉

目的:探讨降低翼状胬肉复发的手术方法。方法:将95例110眼随机分成两组,A组55例63眼采取逆向方法分离翼状胬肉,术中应用丝裂霉素(MMC)及自体结膜瓣移植术,B组常规手术组40例47眼,其中男16例18眼,女24例29眼,年龄28～67(平均41.15)岁,观察两组复发率及角膜上皮愈合时间的情况。结果:随访6～12mo,A组复发率为3.2%;B组复发率为36.2%,复发率比较差异有统计学意义(χ2=9.57,P<0.01)。角膜创面上皮愈合时间:A组平均为4.6±1.2d,B组平均为8.1±0.9d,角膜创面上皮愈合时间两组差异有统计学意义(t=13.08,P<0.01)。结论:逆向方法联合MMC及自体结膜瓣转移术治疗翼状胬肉是一种取材方便,操作简单易学,术后角膜创面恢复快、透明、光滑、结膜平复、复发率低的优点,该方法疗效确切,是理想的手术方式,值得在基层医院推广。

Clinical analysis of risk factors contributing to recurrence of pterygium after excision and graft surgery

AIM:To find the risk factors related to the reproliferation of the pterygial tissue after excision and graft surgery.METHODS:Charts of 130 eyes of 130 patients who had pterygial excision from March 2006 to April 2011 were reviewed. Preoperative pterygium morphology, surgical methods, and adjunctive treatments were statistically analyzed for their relationship with recurrence.RESULTS: During the follow-up period, recurrence was observed in 20 eyes (15.4%). None of the preoperative morphologic features were affected the rate of the recurrence. However, an age < 40y [P =0.085, odds ratio (OR) 3.609, 95% confidence interval (CI) 0.838-15.540] and amniotic membrane graft instead of conjunctival autograft (P =0.002, OR 9.093, 95% CI 2.316-35.698) were statistically significant risk factors for recurrence. Multivariate analysis revealed that intraoperative mitomycin C (MMC) (P=0.072, OR 0.298, 95% CI 0.080-1.115) decreased the rate of recurrence.CONCLUSION:Younger age is a risk factor for reproliferation of pterygial tissue after excision and amniotic membrane transplantation (AMT) are less effective in preventing recurrence of pterygium after excision based on the comparison between conjunctival autograft and AMT. Intraoperative MMC application and conjunctival autograft reduce recurrence.
