Abstract
BackgroundSurgery is the gold standard for the treatment of malignant tumors of the rectum. Intestinal anastomotic leakage remains a serious complication of colorectal surgery. The efficacy and safety of transrectal endoscopic drainage by vacuum therapy in patients with intestinal anastomotic leakage after surgical treatment of middle and distal rectal tumors were assessed.MethodsProspective analysis of treatment outcomes among patients undergoing surgery for middle and distal rectal tumors at the Department of General, Gastroenterological, and Oncological Surgery of the Ludwik Rydygier Collegium Medicum in Bydgoszcz and Nicolaus Copernicus University in Torun from 2016 to 2019 was conducted.ResultsSeventy-nine patients with middle and distal rectal tumors underwent laparoscopic resection. Intestinal anastomotic leak was identified in 18 (22.79%) patients [all men, mean age 61.39 (43–86) years] during the postoperative period. Primary protective ileostomy was performed in 8/18 (44.44%) patients. All 18 patients were treated with endoluminal vacuum therapy via transrectal endoscopic drainage. The mean time from surgery to the diagnosis of leakage and initiation of endoscopic treatment was 16 (3–728) days. The mean number of endoscopic procedures per patient was 6 (1–11). The mean duration of endoscopic treatment was 22 (4–43) days. Complications of endotherapy occurred in 2/18 (11.11%) patients treated endoscopically for bleeding from the abscess cavity. Success of endoluminal vacuum therapy was achieved in 17/18 (94.44%) patients. Moreover, 5/18 (27.78%) patients required ileostomy during the endoscopic treatment. The mean follow-up period was 368 (118–724) days. Long-term success of transrectal endoscopic drainage using vacuum-assisted therapy was achieved in 15/18 (83.33%) patients.ConclusionsEndoscopic rectal drainage using vacuum-assisted therapy is an effective and safe minimally invasive treatment in patients with intestinal anastomotic leaks following resection procedures within the middle and distal rectum.
Highlights
Surgery is the gold standard for the treatment of malignant tumors of the rectum
This study introduces some novelties to the state of knowledge in order to improve endoscopic treatment’s results in patients with anastomotic leaks following rectal cancer resection
Innovatory treatment approach based on the diameter of anastomotic leak and its endoscopic image was presented, which is strictly connected with time from surgery
