BACKGROUND: The prognosis of right colon cancer remains disappointing. Complete mesocolic excision (CME) with central vascular ligation (CVL), based on the same oncological principles of total mesorectal excision, has been speculated to result in a better outcome. To evaluate the oncological adequacy of CME with CVL, we carried out a comparative study with propensity score-matched analysis between two different surgical procedures performed at Italian and Egyptian University cancer centers...

Total robotic resection of mid- and low rectal cancers confers technical advantages within the confines of the pelvis and allows difficult rectal cancer cases to be performed efficiently with less risk of conversion to open. To maximize the advantage of robotic surgery, we utilize the technique of single docking totally robotic dissection for rectal cancer for both the Da Vinci Si and Xi Surgical Systems. All steps are performed robotically, with the surgery divided into two phases. The first phase consists of inferior mesenteric artery and vein ligation, sigmoid and descending colon mobilization and splenic flexure takedown...

OBJECTIVE: To evaluate the feasibility, safety, radicality and short-term outcome of preserving left colic artery (LCA) during laparoscopic total mesorectal excision (TME) for the treatment of rectal cancer. METHODS: From January 2013 to December 2016,136 patients with mid-lower rectal cancer received laparoscopic TME in the Gastrointestinal Surgery Department of Taizhou People's Hospital of Jiangsu Province. Patients with rectal tumor within 10 cm to the anal verge were enrolled into the study...

OBJECTIVE: To investigate the surgical endpoint of separation of mesorectum during total mesorectal excision (TME), suggesting the concept of "terminal line", in order to perform above separation better for middle-low rectal cancer. METHODS: Gross anatomy of mesorectum endpoint from 81 surgical specimens of low anterior resection (LAR, 5 to 6 cm of distance from low margin of cancer to anal edge) and 71 surgical specimens of abdominal perineal resection(APR, <5 cm of distance from low margin of cancer to anal edge) was observed...

BACKGROUND: Lateral pelvic lymph node dissection (LPND) is a challenging procedure due to its technical difficulty and higher incidence of surgical morbidity. We compared short-term outcomes between laparoscopic and robotic LPND in patients with rectal cancer. METHODS: Between May 2006 and December 2014, prospectively collected data from consecutive patients undergoing robotic or laparoscopic total mesorectal excision (TME) with LPND were retrospectively compared...

INTRODUCTION: Intraabdominal visceral obesity may increase technical challenges during laparoscopic rectal resection and hypothetically therefore increase the risk of perioperative complications. The aim of this study was to analyze intraabdominal obesity by means of perirenal fat against risk of adverse outcomes in patients undergoing laparoscopic rectal cancer surgery. METHODS: This study was a single-institution retrospective analysis of consecutive patients undergoing laparoscopic total mesorectal surgery for rectal cancer between January 2009 and January 2013...

BACKGROUND: Short-term results have shown that transanal total mesorectal excision is safe and effective for patients with mid to low rectal cancers. Transanal total mesorectal excision is considered technically challenging; thus, adoption has been limited to a few academic centers in the United States. OBJECTIVE: The aim of this study is to describe outcomes after the initiation of a transanal total mesorectal excision program in the setting of an academic colorectal training program...

Aims: To evaluate the impact of body mass index (BMI) on the surgical outcome of laparoscopic total mesorectal excision (laTME) for locally advanced rectal cancer (LARC, clinically staged as UICC stage II/III) after neoadjuvant chemoradiotherapy (nCRT). Methods: 312 LARC patients undergoing laTME after nCRT were divided into nonobese (BMI < 25.0 kg/m(2), n = 249) and obese (BMI ≥ 25.0 kg/m(2), n = 63) groups. Preoperative radiotherapy was delivered in 45-50...

BACKGROUND: Transanal total mesorectal excision (TaTME) seems to be a valid alternative to the open or laparoscopic TME. Quality of the TME specimen is the most important prognostic factor in rectal cancer. This study shows the pathological results of the largest single-institution series published on TaTME in patients with mid and low rectal cancer. METHODS: We conducted a retrospective cohort study of all consecutive patients with rectal cancer, treated by TaTME between November 2011 and June 2016...

OBJECTIVE: To compare short-term results of total mesorectal excision (TME) for mid and low rectal cancer, achieved by transanal (TaTME), laparoscopic (LaTME), and open (OpTME) approaches. BACKGROUND: The impact of TaTME on the surgical treatment of mid and low rectal cancer has yet to be clarified. METHODS: This is a case-matched study, based on data from a prospectively maintained database of patients who underwent TaTME from May 2015 to March 2017, and a retrospective chart review of patients who underwent LaTME and OpTME in the previous period...

REVIEW
Yushen Qian, Alexander L Chin, Diego A S Toesca, Albert C Koong, Daniel T Chang
Nonoperative management of rectal cancer is an emerging treatment approach that aims to enable carefully selected patients to avoid the morbidity of radical surgical resection, while benefiting from the same excellent rates of tumor control achieved with radical surgery-based combined-modality therapy. The success of nonoperative management in this setting is based on the accurate assessment of tumor eradication after chemoradiotherapy, without pathologic verification. Therefore, clinical evidence of complete response-based on physical examination, endoscopic procedures, and imaging-must be utilized as a marker to predict for pathologic complete response and thus help select the patients who are most appropriate for nonoperative management...

AIM: To assess the clinical significance of prophylactic lateral pelvic lymph node dissection (LPLND) in stage IV low rectal cancer. METHODS: We selected 71 consecutive stage IV low rectal cancer patients who underwent primary tumor resection, and enrolled 50 of these 71 patients without clinical LPLN metastasis. The patients had distant metastasis such as liver, lung, peritoneum, and paraaortic LN. Clinical LPLN metastasis was defined as LN with a maximum diameter of 10 mm or more on preoperative pelvic computed tomography scan...

BACKGROUND: The success of transanal endoscopic microsurgery (TEM) for early rectal cancer depends on proper indications and strict patient selection. When unfavorable pathologic features are identified after TEM operation, total mesorectal excision is recommended to minimize the risk of recurrence. In this study, data were collected in a retrospective series of patients to determine the results of laparoscopic reoperation after TEM. METHODS: All patients underwent an accurate rectal-digital examination and clinical tumor staging by transanal endosonography, CT, and/or MRI...

BACKGROUND: Transanal total mesorectal excision (taTME) is an altogether different approach to rectal cancer surgery, and the effects of carbon dioxide (CO2) on this dissection remain poorly described. METHODS: This article critically examines the effect of carbon dioxide insufflation and the workspace it creates during the process of taTME. The unique aspects of insulation with this approach are governed by the laws of physics, especially the principles of fluid dynamics, an area that remains poorly described for laparoscopy and not at all described for taTME...

BACKGROUND: The aim of this study was to evaluate the clinical outcome of transanal local excision for cT1/cT2 lower rectal cancer following pre-operative chemoradiation therapy (CRT). PATIENTS AND METHODS: Eleven patients who underwent pre-operative CRT for cT1/cT2 lower rectal cancer were retrospectively enrolled in this study. Surgical outcomes were compared between the group that underwent trasanal local excision (TLE) (n=6) and that which underwent total mesorectal excision (TME) (n=5)...

AIM: To detect the existence of isolated cancer cells in the mesentery of colorectum (named as Metastasis V), and investigate its clinical significance in colorectal cancer (CRC) patients. METHODS: Sixty-three CRC patients who received radical excision between January 2012 and September 2015 were included. All the patients underwent laparoscopy-assisted radical colorectomy or proctectomy [with complete mesocolic excision (CME) or total mesorectal excision (TME)] with R0 dissections at the Department of Gastrointestinal Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology...
