Abstract

Introduction: Melanosis coli is a benign lesion associated withthe overuse of laxatives containing anthraquinone. The aimof this study is to determine whether melanosis recovers afterthe discontinuation of laxatives and whether this condition isassociated with a higher incidence of colon polyps or cancercompared to the general population.Methods: Patients with confirmed melanosis coli wereperformed a repeat colonoscopy and biopsy 2 years later andtheir histopathological examination results were compared.Data on age, sex, the use of any medicinal laxative or herbals,the presence of findings after the discontinuation of laxatives,constipation, colon polyp, and the relationship with coloncancer were examined. The similarity of segments and theirrelationships in the first and control colonoscopies wereinvestigated in cases detected to have melanosis coli.Results: All 104 patients included in the study were sufferingfrom constipation. While the number of patients usinglaxatives or herbal tea was initially 96, it was 24 at the time offollow-up colonoscopy. Although the majority of subjects haddiscontinued laxatives, histological findings of melanosis colipersisted in 88 of 104 subjects. Mostly descending colon andrectum were involved.Conclusion: It is thought that the findings of melanosis colidisappear in about 6 months following the discontinuation oflaxative drugs and herbal teas. However, it was detected in ourseries that while the macroscopic findings were mostly healedeven in the follow-up after two years, microscopic findings ofmelanosis coli continued to remain. No relationship was foundbetween melanosis coli and the development of colon cancerand polyp. In the present study, it was aimed to emphasizethat melanosis coli’s becoming chronic and its creating apredisposition to colon cancer should be investigated withlonger follow-ups and some herbal teas may cause a long-termchange in the colon mucosa.

Özet

Amaç: Melanozis koli antrakinon içeren laksatiflerin fazla kullanımına bağlı olarak ortaya çıkan benign bir lezyon olarak düşünülür. Çalışmanın amacı melanozis kolili hastaların laksatiflerle ilişkisi, laksatif bırakılınca iyileşip iyileşmediği, normal popülasyona göre kolon polibi ve kolon kanseri ile ilişkili olup olmadığını saptamaktır. Yöntemler: Kolonoskopi ile melanozis koli saptanan olgulara 2 yıl sonra kontrol kolonoskopisi yapıldı ve histopatoloji sonuçları karşılaştırıldı. Olguların yaşları, cinsiyetleri, laksatif ilaç veya bitki çayı kullanıp kullanmadığı, laksatif kullananların bıraktıktan sonra bulgularının devam edip etmediği, konstipasyon, kolon polibi ve kolon kanseriyle ilişki olup olmadığı araştırıldı. Melanozis koli saptanan olguların ilk ve kontrol kolonoskopilerindeki segmentlerin benzerliği ve ilişkisi araştırıldı. Bulgular: Çalışmaya alınan 104 olgunun hepsinde konstipasyon mevcuttu. Laksatif ilaç veya çay kullanan olgu sayısı ilk başta 96 idi, kontrolde ise 24 hasta laksatif ilaç veya çay kullanmaya devam ediyordu. Olguların büyük çoğunluğu laksatif kullanımını bıraktığı halde 104 olgunun 88’inde histopatolojik olarak melanozis koli bulguları devam etmekteydi. Çalışmamızda en sık sol kolon ve rektum tutulmuştu. Sonuç: Melanosis coli bulgularının laksatif ilaç veya çayların kullanımı bırakıldıktan yaklaşık 6 ay sonra düzeldiği düşünülmektedir. Fakat bizim serimizde 2 yıl sonraki takipte bile büyük çoğunluğunda makroskopik bulgular düzeldiği halde mikroskobik olarak melanosis koli bulgularının devam ettiği saptandı. Çalışmada melanosis koliyle kolon kanseri ve kolon polibi arasında bir ilişki saptanmadı. Melanosis kolinin kronikleşmesinin ve kolon kanserine yatkınlık oluşturup oluşturmamasının daha uzun takiplerle araştırılması gerektiğini ve bazı bitki çaylarının kolon mukozasına uzun süreli değişikliğe yol açabileceğini vurgulamak istedik.
