title: TEMS: results of a specialist centre.
abstract: BACKGROUND
  Transanal endoscopic microsurgery (TEMS) is becoming more widespread due to the increasing body of evidence to support its role. Previous published data has reported recurrence rates in excess of 10% for benign polyps after TEMS.
  
  
  METHODS
  Bradford Royal Infirmary is a tertiary referral centre for TEMS and early rectal cancer in the UK. Data for all TEMS operations were entered into a prospective database over a 7-year period. Demographic data, complications and recurrence rates were recorded. Both benign adenomas and malignant lesions were included.
  
  
  RESULTS
  A total of 164 patients (65% male), with a mean age of 68 years were included; 114 (70%) of the lesions resected were benign adenomas, and 50 (30%) were malignant lesions. Median polyp size was 4 (range 0.6-14.5) cm. Mean length of operation was 55 (range 10-120) min. There were no recurrences in any patients with a benign adenoma resected; two patients with malignant lesions developed recurrences. Three intra-operative complications were recorded, two rectal perforations (repaired primarily, one requiring defunctioning stoma), and a further patient suffered a blood loss of >300 ml requiring transfusion. Six patients developed strictures requiring dilation either endoscopically or under anaesthetic in the post-operative period.
  
  
  CONCLUSIONS
  We have demonstrated that TEMS procedures performed in a specialist centre provide low rates of both recurrence and complication. Within a specialist centre, TEMS surgery should be offered to all patients for rectal lesions, both benign and malignant, that are amenable to TEMS.
