After reversal of the stoma a condition known as low anterior resection syndrome (LARS) can occur characterized by a combination of symptoms such as urgent bowel movements, lack of control over bowel movements, and difficulty fully emptying the bowels. These symptoms have a significant negative impact on the quality of life for individuals who have survived the cancer. Currently, there is limited available data regarding the presence, risk factors, and effects of treatment for these symptoms during long-term follow-up.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aims<\/jats:title>\n                    <jats:p>To evaluate long term outcomes of low anterior resection surgery and its correlation to baseline anorectal manometry (ARM) parameters and physiotherapy with anorectal biofeedback (BF) treatment.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>One hundred fifteen patients (74 males, age 63\u2009\u00b1\u200911) who underwent low anterior resection surgery for rectal cancer were included in the study. Following surgery, patients were managed by surgical and oncologic team, with more symptomatic LARS patients referred for further evaluation and treatment by gastroenterologists. At follow up, patients were contacted and offered participation in a long term follow up by answering symptom severity and quality of life (QOL) questionnaires.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      80 (70%) patients agreed to participate in the long term follow up study (median 4\u2009years from stoma reversal, range 1\u20138). Mean time from surgery to stoma closure was 6\u2009\u00b1\u20094\u2009months. At long term follow up, mean LARS score was 30 (SD 11), with 55 (69%) patients classified as major LARS (score\u2009&gt;\u200930). Presence of major LARS was associated with longer time from surgery to stoma reversal (6.8 vs. 4.8\u2009months;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u20090.03) and with adjuvant chemotherapy (38% vs. 8%;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0=\u20090.01). Patients initially referred for ARM and BF were more likely to suffer from major LARS at long term follow up (64% vs. 16%,\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u20090.001).

Prolonged time until stoma reversal and adjuvant chemotherapy emerged as the primary risk factors for a negative prognosis. It is important to note that referring patients for anorectal physiology testing alone tended to predict poorer long-term outcomes, indicating the presence of selection bias. However, certain measurable manometric parameters could potentially aid in identifying patients who are at a higher risk of experiencing unfavorable functional outcomes. There is a critical need to enhance current treatment options for this patient group.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1186\/s12876-023-03112-8","type":"journal-article","created":{"date-parts":[[2024,1,12]],"date-time":"2024-01-12T10:03:35Z","timestamp":1705053815000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Long term persistence and risk factors for anorectal symptoms following low anterior resection for rectal cancer"],"prefix":"10.1186","volume":"24","author":[{"given":"E.","family":"Koifman","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Armoni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.","family":"Gorelik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Harbi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Y.","family":"Streltsin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
