BACKGROUND: The ideal level of ligation of the inferior mesenteric artery (IMA) during curative resection of sigmoid colon and rectal cancer is still controversial. The aim of this meta-analysis was to examine the impact of high ligation and low ligation of the IMA on anastomotic leakage, overall morbidity, postoperative mortality, and oncological outcomes in patients undergoing surgery for sigmoid colon and rectal cancer. METHODS: PubMed, EMBASE, Web of Science, and BioMed Central databases were searched to identify relevant articles published from May 1953 to March 2018...

AIM: Transanal endoscopic microsurgery (TEM) is used for the resection of large rectal adenomas and well or moderately differentiated T1 carcinomas. Due to difficulty in preoperative staging, final pathology may reveal a carcinoma not suitable for TEM. Although completion total mesorectal excision is considered standard of care in T2 or more invasive carcinomas, this completion surgery is not always performed. The purpose of this article is to evaluate the outcome of patients after TEM-only, when completion surgery would be indicated...

BACKGROUND: Short-course preoperative radiotherapy is indicated in patients with resectable rectal cancer to control local recurrence. Although no clear evidence is available, short-course radiotherapy with operation within a week is common practice. The aim of this study was to investigate the impact of timing of operation for rectal cancer after short-course radiotherapy on anastomotic leakage. STUDY DESIGN: Data from the Dutch Colorectal Audit were used. All patients who received short-course preoperative radiotherapy and underwent elective operation within 14 days for rectal cancer between January 1, 2011 and December 31, 2016 were included...

BACKGROUND: Laparoscopic rectal resection (LRR) for cancer is a challenging procedure, with conversion to open surgery being reported in up to 30% of cases. Since only a few studies with short follow-up have compared converted LRR and open RR (ORR), it is unclear if conversion to open surgery should be prevented by preferring an open approach in those patients with preoperatively known risk factors for conversion. The aim of this study was to compare early postoperative outcomes and long-term survival after completed LRR, converted LRR or ORR for non-metastatic rectal cancer...

AIM: An airtight anastomosis on intra-operative leak testing has been previously demonstrated to be associated with a lower risk of clinically significant postoperative anastomotic leak following left-sided colorectal anastomosis. However, to date, there is no consistently agreed upon method for management of an intra-operative anastomotic leak. Therefore, we powered a noninferiority study to determine whether suture repair alone was an appropriate strategy for the management of an intra-operative air leak...

BACKGROUND: A temporary ileostomy may reduce symptoms from anastomotic leakage after rectal cancer resection. Earlier results of the EASY trial showed that early closure of the temporary ileostomy was associated with significantly fewer postoperative complications. The aim of the present study was to compare health-related quality of life (HRQOL) following early versus late closure of a temporary ileostomy. METHODS: Early closure of a temporary ileostomy (at 8-13 days) was compared with late closure (at more than 12 weeks) in a multicentre RCT (EASY) that included patients who underwent rectal resection for cancer...

BACKGROUND: Anastomotic leakage is a potential major complication after colorectal surgery. The C-seal was developed to help reduce the clinical leakage rate. It is an intraluminal sheath that is stapled proximal to a colorectal anastomosis, covering it intraluminally and thus preventing intestinal leakage in case of anastomotic dehiscence. The C-seal trial was initiated to evaluate the efficacy of the C-seal in reducing anastomotic leakage in stapled colorectal anastomoses. METHODS: This RCT was performed in 41 hospitals in the Netherlands, Germany, France, Hungary and Spain...

BACKGROUND: Tumour response to neo-adjuvant radiotherapy for rectal cancer varies significantly between patients, as classified by Tumour Regression Grade (TRG 0-3), with 0 equating to pathological complete response (pCR) and 3 denoting minimal/no response. pCR is associated with significantly better local recurrence rates and survival, but is achieved in only 20-30% of patients. The literature contains limited data reporting factors predictive of tumour response and corresponding outcomes according to degree of regression...

BACKGROUND: Laparoscopic colorectal cancer operations in obese patients pose technical challenges that may negatively impact oncologic adequacy. A meta-analysis was performed to assess the oncologic outcomes of laparoscopic colorectal cancer resections in obese compared to non-obese patients. Short- and long-term outcomes were assessed secondarily. METHODS: A systematic literature search was conducted from inception until October 01, 2014. Studies that compared outcomes of laparoscopic colorectal malignant neoplasms in obese and non-obese patients were selected for meta-analysis...

BACKGROUND: The use of laparoscopic surgery for colorectal cancer has become widespread recently. However, the safety and oncological outcomes of laparoscopic surgery for primary advanced colorectal cancer need extensive investigation. We analyzed the short- and long-term outcomes after laparoscopic multivisceral resection for primary colon cancer with suspected invasion of other organs at a single institution. METHODS: Between January 2000 and December 2014, 118 patients underwent laparoscopic multivisceral resection for primary colon cancer invading or adhering to adjacent organs or structures; their short- and long-term outcomes were retrospectively evaluated...

BACKGROUND: Several studies have shown the transanal total mesorectal excision (TATME) is emerging as a safe and effective technique for proctectomy. The majority of these studies to date, however, is based on procedures done in centers with teams of two surgeons working simultaneously. Few were performed by single-surgeon teams with sizeable case load. The objective of our study was to identify the feasibility and safety of a single-surgeon TATME. METHODS: Chart review of prospectively collected data on 27 patients who underwent TATME at our institution from June 2015 to September 2016 were included in this study...
