Simple instruments facilitating achievement of transanal total mesorectal excision in male patients.

Aim: To assess the efficacy of a modified approach with transanal total mesorectal excision (taTME) using simple customized instruments in male patients with low rectal cancer.

Methods: A total of 115 male patients with low rectal cancer from December 2006 to August 2015 were retrospectively studied. All patients had a bulky tumor (tumor diameter ≥ 40 mm).

Prognostic Value of Lymph Node Ratio in Locally Advanced Rectal Cancer Patients After Preoperative Chemoradiotherapy Followed by Total Mesorectal Excision.

Although the absolute number of positive lymph nodes (LNs) has been established as 1 of the most important prognostic factors in rectal cancers, many researchers have proposed that the lymph node ratio (LNR) may have better predicted outcomes. We conducted a retrospective study to compare the predictive ability of LNR and ypN category in rectal cancer. A total of 264 locally advanced rectal cancer (LARC) patients who underwent preoperative chemoradiotherapy (CRT) followed by total mesorectal excision (TME) between 2005 and 2012 were reviewed.

[A procedure to assist achievement of total mesorectal excision through the extending intersphincteric plane].

Objective: To investigate the value of assisted achievement total mesorectal excision (TME) through the extending intersphincteric plane.

Methods: From February 2006 to April 2010, 65 patients with low rectal cancer underwent assisted implementing TME through the extending intersphincteric plane under direct vision and achieved sphincter preservation. The clinical data was summarized and analyzed retrospectively.

[Laparoscopic total mesorectal excision combined with intersphincteric resection for ultra-low rectal cancer].

Objective: To evaluate clinical outcomes after laparoscopic total mesorectal excision (TME) combined with intersphincteric resection (ISR) for ultra-low rectal tumors.

Methods: Clinical data of 36 patients with ultra-low rectal tumor undergoing laparoscopic TME combined with ISR were analyzed retrospectively.

Results: The median distance from the inferior margin of the tumor to the anal verge was 3.

[Value of protective stoma in intersphincteric resection for ultra-low rectal cancer].

Objective: To investigate the value of protective stoma in intersphincteric resection (ISR) for ultra-low rectal cancer.

Methods: Clinical data of 56 ultra-low rectal cancer patients without involvement of external anal sphincter treated during January 1999 to July 2009 with trans-anal ISR plus trans-abdominal total mesorectum excision and coloanal anastomosis were retrospectively analyzed. The patients were divided into two groups based on whether they received protective ostomy: ostomy group (16 cases) and ostomy-free group (40 cases).

[Application of Altemeier procedure in the emergent management of acute incarcerated rectal prolapse].

Objective: To evaluate the perineal rectosigmoidectomy(Altemeier procedure) in the emergent management of acute incarcerated rectal prolapse.

Methods: Clinical and follow-up data of 9 patients with acute incarcerated rectal prolapse undergone Altemeier procedure were retrospectively analyzed.

Results: The mean operation time was 1.

[Clinical application of intersphincteric resection in the anal-preserving operation for ultra-low rectal carcinoma].

Objective: To investigate the clinical application of intersphincter resection (ISR) combined with total mesorectal excision (TME) and colon-anal anastomosis in the treatment for ultra-low rectal carcinoma.

Methods: To review and analyze retrospectively the data of 34 patients with ultra-low rectal carcinoma (without external anal sphincter involvement) who received treatment of ISR, TME and colon-anal anastomosis.

Results: Partial resection of internal sphincter was performed in the patients with a distal edge of the tumor greater than or equal to 2 cm from the dentate line.

[Combination of trans-anal intersphincteric resection and trans-abdominal total mesorectal excision for anus-retained ultra-low rectal tumors].

Objective: To study the combination of trans-anal intersphincteric resection and transabdominal total mesorectal excision for anus-retained ultra-low rectal tumors.

Methods: Clinical data of 34 ultra-low rectal tumor patients without external anal sphincter involved, who underwent the combination surgery, were retrospectively analyzed.

Results: The distance from the distal incisal margin of the rectum to the inferior margin of the tumor ranged from 1.
