Forskningsöversikt (refereegranskat)abstract
- Since 1,5 years wireless enteroscopy with the GivenM2A-capsule has been tested clinically. Wireless capsule-enteroscopy (WCE) has already contributed significantly to the understanding of patients with obscure intestinal symptoms. Series of occult bleeders show that WCE detects lesions in 60%, whereas enterography only in 15%, and push-enteroscopy in 25%. Lesions detected are angiodysplasia in 55%, ulcerations in 14%, aphtoid lesions and erosions in 11%, tumours in 8%. Active bleeding was seen in 43%. In patients with Crohn’s disease further information on extent of disease and type of lesions is gained, mainly seen as erosions in 64%. WCE in hereditary polyposis disclosed more and bigger lesions, and in celiac enteropathy villous atrophy and scalloping of the mucous membrane is readily identified. Software to locate the capsule in the gastrointestinal tract is recently launched together with a graphic display of capsule track and transit times. Soon displays for motility and pressure will follow. Capsule adaptation for screening for Barrett’s esophagus and colon cancer might come true.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Konceptet att sågtandande polyper kan leda till kolorektal cancer är relativt nytt. Sågtandade polyper orsakar upp till en tredjedel av all sporadisk kolorektal cancer. Trots detta är kunskaperna om sågtandade polypers etiologi, incidens, prevalens och naturalförlopp ofullständiga. Sågtandade polyper är svåra att identifiera och ta bort endoskopiskt. Endoskopister och patologer måste ha kunskaper om sågtandade adenom för att effektivt kunna detektera, diagnostisera och ta bort dem som led i att minska antalet personer som drabbas av kolorektal cancer. The concept that serrated polyps can cause colorectal cancer is relatively new and not very well-known. Serrated polyps are difficult to identify and treat endoscopically. This together with the fact that premalignant serrated polyps are mainly located in the proximal colon might help explain why colonoscopy is less effective against right-sided compared to left-sided colorectal cancers and why interval cancers usually appear in the proximal colon. In fact, serrated polyps may cause up to one third of all sporadic colorectal cancers. In spite of this, the aetiology, incidence, prevalence and natural history of serrated polyps remains elusive. Endoscopists and pathologists must have a good understanding of serrated polyps in order to effectively diagnose, treat and follow up these lesions. This review focuses on the pathophysiology, types, work-up, treatment and follow-up of serrated polyps in the colon and rectum.
