Objective assessment used standardised criteria and scoring systems (Rome III criteria, Wexner and Vaizey scoring systems) to: (A)
document the presence of individual symptoms of bowel dysfunction; and (B) when present, group symptoms together to allow stratification of patients into those with: (i) evacuation dysfunction, defined as having 2 or more symptoms of obstructed defaecation; (ii) storage dysfunction, defined as faecal incontinence and/or having 2 or more click here symptoms of bowel frequency, loose stools, urgency, incontinence to flatus or need to wear a pad/plug for faecal soiling; (iii) both evacuation and storage dysfunction, or (iv) neither – criteria not met. These outcome measures were modelled against important clinicopathological features, including age, use of radiotherapy, and technical details, including anastomotic height measured from the anal verge, and time since surgery. Results: Of the 754 patients who underwent surgery,
Selleck Erlotinib 476 were alive and without stoma at the time of the study. Of these, 338 (71%) agreed to participate (199M, 69 years). Subjectively, over one quarter (26.4%) of patients were dissatisfied with their current bowel function, and over one third (36.4%) had sought medical attention specifically for post-operative bowel dysfunction. Only one third (36.4%) judged their current bowel function as ‘normal’, and two-thirds
(62.2%) felt their bowel function had changed since surgery, with most reporting increased frequency and looser stools. Objectively, at least one symptom of bowel dysfunction was present in 93% of patients. Notably, of the top 10 individual symptoms reported, 6 were reflective of evacuation dysfunction, with two thirds of patients each reporting sensation of incomplete emptying (67.2%) and need for toilet revisiting (63.4%). Following stratification, 85% of all patients met criteria 上海皓元医药股份有限公司 for either evacuation or storage dysfunction. Over half of all patients (51%) described coexisting evacuation and storage dysfunction; 23% met criteria for evacuation dysfunction alone; and 11% met criteria for storage dysfunction alone. Patients with a combination of evacuation and storage dysfunction had significantly lower satisfaction scores (P < 0.001) and higher rates of seeking medical attention. Anastomotic height was ≤5 cm in 26%, 6–10 cm in 23%, and 11–15 cm in 51% of subjects. Lower anastomoses were associated with storage dysfunction (P < 0.001) but not evacuation dysfunction. Neither gender nor radiotherapy with associated with storage or evacuation dysfunction. Conclusions: Individual symptoms of bowel dysfunction are ubiquitous following anterior resection surgery, with evacuation dysfunction being more prevalent than storage dysfunction.
