Survival outcome of adjuvant radiotherapy after local excision for T2 early rectal cancer: An analysis based on the surveillance, epidemiology, and end result registry database.

Background: Major resection (MR) is recommended for cases with T2 finding after local excision (LE) of early rectal cancer, but the revision procedure is accompanied with high morbidity. We evaluated the oncological safety of LE followed by adjuvant radiotherapy as a rectum-preserving alternative to MR for T2 early rectal cancer.

Methods: A total of 3786 patients with T2N0M0 rectal adenocarcinoma between 1998 and 2013 were included from the SEER database.

Risk Factors for Early Postoperative Small Bowel Obstruction after Elective Colon Cancer Surgery: An Observational Study of 1,244 Consecutive Patients.

Background: Early postoperative small bowel obstruction (EPSBO) is a common complication following colon cancer surgery. EPSBO is associated with increased hospital stays, mortality rates, and healthcare costs. The purpose of this study was to identify risk factors for EPSBO following elective colon cancer surgery.

Effect of Neoadjuvant Chemoradiotherapy on Locally Advanced Rectal Mucinous Adenocarcinoma: A Propensity Score-Matched Study.

To compare the surgical and oncological outcomes of rectal mucinous adenocarcinomas treated with neoadjuvant chemoradiotherapy versus surgery alone. A total of 167 locally advanced rectal mucinous adenocarcinoma patients treated with neoadjuvant chemoradiotherapy and surgery alone between 2008 and 2014 were matched using propensity score; the surgical and oncological outcomes were compared. Ninety-six patients were matched.

A scoring system basing pathological parameters to predict regional lymph node metastasis after preoperative chemoradiotherapy for locally advanced rectal cancer: implication for local excision.

Local excision is an alternative to radical surgery that is indicated in patients with locally advanced rectal cancer (LARC) who have a good response to chemoradiotherapy (CRT). Regional lymph node status is a major uncertainty during local excision of LARC following CRT. We retrospectively reviewed clinicopathologic variables for 244 patients with LARC who were treated at our institute between December 2000 and December 2013 in order to identify independent predictors of regional lymph node metastasis.

Laparoscopic transabdominal approach partial intersphincteric resection for low rectal cancer: surgical feasibility and intermediate-term outcome.

Background: Traditionally, conventional intersphincteric resection requires a combined abdominal and perineal approach and a handsewn coloanal anastomosis procedure, which is difficult to accomplish via the perineal approach. A completely abdominal approach partial intersphincteric resection (APISR) with laparoscopy can simplify the anastomosis procedure. This study evaluated the intermediate-term oncological and functional results of laparoscopic versus open APISR for low rectal cancer.

[Risk factors of postoperative chyle leak following complete mesocolic excision for colon cancer].

Objective: To investigate the incidence, risk factors and preventative methods associated with chyle leak following complete mesocolic excision(CME) for colon cancer.

Methods: Clinical data of 592 patients with colon cancer undergoing CME in the department of Colorectal Surgery in the Fujian Medical University Union Hospital from September 2000 to September 2011 were analyzed retrospectively.

Results: Chyle leak occurred in 46 patients(7.

[Comparing the influencing factors of anastomotic bleeding in rectal carcinoma resection between laparoscopic and open radical approaches].

Objective: To observe the occurrence of anastomotic bleeding following laparoscopic and open radical resection for rectal carcinoma, and to explore its contributing factors.

Methods: Two hundred and sixty-three cases of rectal carcinoma undergone radical resection were divided into 2 groups, laparoscopic surgery (LS) group (n=86) and open surgery (OS) group (n=177). According to the different locations of anastomotic stoma and with or without preventive colostomy, the two groups were divided into AR sub-group and LAR/UAR sub-group, colostomy sub-group and non-colostomy sub-group.

[Comparison of surgical complication rate between laparoscopic and open radical resection for colorectal cancer].

Objective: To compare the surgical complication rate between laparoscopic and open radical resection for colorectal cancer.

Methods: From September 2000 to December 2005, 491 cases with colorectal cancer were divided into two groups prospectively and nonrandomly,and received radical laparoscopic operation (LP, n=214) and open operation (OP, n=277). The intra- and post-operative complication rate were compared between the two groups.
