Transanal endoscopic microsurgery as day surgery - a single-centre experience with 500 patients.
Colorectal Disease 2018 October
AIM: Transanal endoscopic microsurgery (TEM) is the current treatment of choice for rectal adenomas and early rectal cancer. Postoperative admission to hospital is common but possibly unnecessary. Our objective was to analyse predictors and outcomes of TEM patients having same day discharge (TEM-D) compared with those who were admitted to hospital (TEM-A).
METHOD: At St Paul's Hospital (SPH), demographic, surgical, pathological and follow-up data have been collected prospectively since TEM was started in 2007. Trends in admission and readmission rates were analysed using the Cochran-Armitage trend test, and predictors of admission were analysed using univariate and multivariate logistic regressions.
RESULTS: Between 2007 and 2016, 500 patients were treated by TEM at SPH. The overall admission rate was 29% (145/500), but this decreased to 19% in the last 3 years of the study (P < 0.001). The readmission rate was 5.2% (n = 26/500) and did not change significantly over the study period (P = 0.30). Reasons for admission included the following: surgeon discretion/monitoring (35%), urinary retention (26%), haemorrhage (10%), breach of peritoneal cavity (7%), infection (7%) and other (15%). The most common reasons for readmission were haemorrhage (54%, n = 14), pain (19%, n = 5) and infection (12%, n = 3). Factors associated with admission were as follows: tumour height (OR 1.09, 1.02-1.17), prolonged operative time (OR 1.25, 1.14-1.37), unsutured surgical defect (OR 1.99, 1.22-3.25) and surgeon experience (OR 4.62, 2.75-7.77).
CONCLUSION: Outpatient TEM is safe and carries a low risk of readmission. In centres with an outpatient TEM strategy, predictors of hospital admission include proximal tumours, prolonged surgical time and open management of the surgical defect.
