title: Total mesorectal excision with water-jet dissection in patients with rectal cancer: surgical and morphological aspects.
abstract: OBJECTIVE
  This publication will describe our own experience of using the ERBEJET2(®) water-jet dissector during surgical interventions for rectal cancer.
  
  
  METHODS
  We utilized the water-jet dissection technique to obtain tissue specimens in 10 patients with rectal cancer. All patients thus underwent nerve-sparing low anterior resection of the rectum along with para-aortic lymphadenectomy. No intraoperative complications were registered. The postoperative period went uncomplicated in all patients. No dysuria was observed. Obtained tissue specimens were examined morphologically. Macroscopic examination included assessments of the preservation of the rectal fascia propria and the amount of cellular tissue along the anterior, posterior, and lateral surfaces of the rectum. We performed microscopy of the circumferential resection margin to characterize the surgical clearance and the intensity and depth of damage to the mesorectal tissue. On morphological examination, the quality of mesorectal excision was found to be good (Grade 3) in all 10 patients.
  
  
  RESULTS
  As the results of our study demonstrate, the depth of lateral tissue damage is minimal with the water-jet dissector.
  
  
  CONCLUSIONS
  Water-jet dissectors have their own place in the long list of armamentarium used in surgical interventions performed for rectal cancer and contribute to improving oncological and functional outcomes of surgical treatment in this patient population.
