Colorectal cancer

OBJECTIVE: The aim of this study was to assess whether association of laparoscopic approach and full fast track multimodal (FFT) management can reduce postoperative morbidity after colorectal cancer surgery, as compared to laparoscopic approach with limited fast-track program (LFT). SUMMARY OF BACKGROUND DATA: Recent advances in colorectal cancer surgery are introduction of laparoscopy and FFT implementation. METHODS: Patients eligible for elective laparoscopic colorectal cancer surgery were randomized into 2 groups: FFT or LFT care (with only early oral intake and mobilization starting on Day 1)...

OBJECTIVE: The aim of the study was to analyze data from an international collaboration, and ascertain prognostic indicators that inform clinical decision-making and practices regarding the role of pelvic exenteration for locally advanced primary rectal cancer (LARC). BACKGROUND: With improved national screening programs fewer patients present with LARC. Despite this, select cohorts of patients require pelvic exenteration. To date, the majority of outcome data are from single-center series...

OBJECTIVE: The aim of this study was to evaluate the safety and efficacy of elective rectal resection for rectal cancer in adults by robotic surgery compared with conventional laparoscopic surgery. SUMMARY OF BACKGROUND DATA: Technological advantages of robotic surgery favor precise dissection in narrow spaces. However, the evidence base driving recommendations for the use of robotic surgery in rectal cancer primarily hinges on observational data. METHODS: We searched MEDLINE, Embase, and CENTRAL for randomized controlled trials (until August 2016) comparing robotic surgery versus conventional laparoscopic surgery...

BACKGROUND: The surgical management of transverse colon cancer (TCC) is still not standardized. The aim of this meta-analysis was to evaluate the effect of laparoscopic colectomy (LC) for treatment of TCC in terms of short-term and long-term outcomes compared with open colectomy. METHOD: A systematic literature search with no limits was performed in PubMed and Embase. The last search was performed on September 15, 2016. The short-term outcomes included intraoperative outcomes, postoperative outcomes, and oncological surgical quality...

BACKGROUND: Incisional surgical site infection (SSI) is one of the most frequent complications that occur after colorectal surgery. Surgery for colorectal perforation carries an especially high risk of incisional SSI because fecal ascites contaminates the incision intraoperatively, and in patients who underwent stoma creation, the incision is located near the infective origin and is subject to infection postoperatively. Although effectiveness of the preventive SSI bundle of elective colorectal surgery has been reported, no study has focused exclusively on emergency surgery for colorectal perforation...

BACKGROUND: To identify factors affecting the harvest of lymph nodes (LNs) and to investigate the association between examining a minimum of 12 LNs and clinical outcomes in stage I-III colorectal cancer (CRC) patients. METHODS: The clinicopathologic features and the number of examined LNs for 1167 stage I-III CRC patients were analyzed to identify factors affecting the number of LNs harvested and the correlations between clinical outcomes and high harvests (≧12 LNs) and low harvests (<12 LNs)...

BACKGROUND: Intersphincteric resection (ISR) has become an increasingly popular optional surgical tool for the treatment of very low rectal cancer. The purpose of this study was to assess the long-term oncological and functional outcomes of intersphincteric resection for T2 and T3 rectal cancer situated below 4 cm from the anal verge. METHODS: A total of 62 consecutive patients with very low rectal cancer who underwent ISR from 2001 to 2010 were classified into standard ISR for T2 lesions (Group I, n = 24) and extended ISR for T3 lesions (Group II, n = 38)...

BACKGROUND: The use of Hartmann's procedure in the old and frail and/or in patients with fecal incontinence is increasing, even though some data have reported high postoperative rates of pelvic abscesses. Abdominoperineal excision with intersphincteric dissection has been proposed as a better alternative and is performed increasingly both nationally and internationally. However, no studies have been performed to support this. The aim of this study is to randomize patients between Hartmann's procedure and abdominoperineal excision with intersphincteric dissection and compare post-operative surgical morbidity and quality of life...

AIM: High-dose-rate brachytherapy (HDRBT) appears to be associated with less treatment-related toxicity compared with external beam radiotherapy in patients with rectal cancer. The present study compared the effect of preoperative treatment strategies on overall survival, cancer-specific deaths, and local recurrences between a Dutch and Canadian expert center with different preoperative treatment strategies. PATIENTS AND METHODS: We included 145 Dutch and 141 Canadian patients with cT3, non-metastasized rectal cancer...

OBJECTIVE: When comparing performance across hospitals it is essential to consider the noise caused by low hospital case volume and to perform adequate case-mix adjustment. We aimed to quantify the role of noise and case-mix adjustment on standardized postoperative mortality and anastomotic leakage (AL) rates. METHODS: We studied 13,120 patients who underwent colon cancer resection in 85 Dutch hospitals. We addressed differences between hospitals in postoperative mortality and AL, using fixed (ignoring noise) and random effects (incorporating noise) logistic regression models with general and additional, disease specific, case-mix adjustment...

AIM: The efficacy of neoadjuvant chemotherapy without radiation (NAC) in the treatment of rectal cancer remains unclear. This retrospective study was aimed at determining the pathological complete response rate and short-term outcomes of NAC in patients with locally advanced rectal cancer. PATIENTS AND METHODS: We collected data on 159 consecutive patients treated for rectal cancer (cT3/cT4a, cN+, and cM0 status) at five tertiary referral hospitals between 2005 and 2010...

BACKGROUND/AIMS: The prematurely closed Stent-In II trial in patients with left-sided obstructive colon cancer may have influenced clinical decision making in The Netherlands. The aim of this study was to evaluate treatment of left-sided malignant colon obstruction at a population level since then. METHODS: Short-term outcomes of all patients who underwent resection for left-sided obstructive colon cancer between 2009 and 2012 were assessed based on a prospective national registry...

BACKGROUND: Gastrointestinal stromal tumours (GISTs) of the rectum often require radical surgery to achieve complete resection. This study investigated the management and outcome of surgery for rectal GISTs and the role of imatinib. METHODS: A cohort study was undertaken of patients identified from a database at one tertiary sarcoma referral centre over a continuous period, from January 2001 to January 2013. RESULTS: Over 12 years, 19 patients presented with a primary rectal GIST...

BACKGROUND: Some recent studies have suggested that laparoscopic surgery for colorectal cancer may provide a potential survival advantage when compared with open surgery. This study aimed to compare cancer-related survivals of patients who underwent laparoscopic or open resection of colon cancer in the same, high volume tertiary center. METHODS: Patients who had undergone elective open or laparoscopic surgery for colon cancer between January 2002 and December 2010 were analyzed...

OBJECTIVE: To determine the association between preoperative bowel preparation and 30-day outcomes after elective colorectal resection. METHODS: Patients from the 2012 Colectomy-Targeted American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database who underwent elective colorectal resection were included for analysis and assigned to 1 of 4 groups based on the type of preoperative preparation they received [combined mechanical and oral antibiotic preparation (OAP), mechanical preparation only, OAP only, or no preoperative bowel preparation]...

BACKGROUND: Routine preoperative mechanical bowel preparation (MBP) for left-sided colorectal resections remains controversial. This study aims to evaluate the association between MBP and 30-day anastomotic leaks. METHODS: A retrospective cohort study was conducted using data from the National Surgical Quality Improvement Program from 2011 to 2012. Multiple imputation was used for missing data, and a multivariable logistic regression was performed to adjust for clinically relevant variables...

BACKGROUND: Single-port surgery is a recent advancement in minimally invasive techniques for colon disease. However, single-port laparoscopic rectal resection (SPLR) is rare. The aim of this study was to compare the short-term results of SPLR with those of multi-port laparoscopic rectal resection (MPLR) for rectal cancer. METHODS: Patients who underwent SPLR (n = 50) or MPLR (n = 50) for rectal cancer from July 2010 to March 2014 were analyzed. Patients with tumor diameter less than 40 mm and body mass index less than 30 kg/m(2) were matched for age, sex, tumor location, and preoperative evaluation...
