BACKGROUND AND OBJECTIVES: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) can offer long-term survival to patients with resectable peritoneal metastasis (PM) from colorectal cancer (CRC), a condition with otherwise dismal prognosis. This study describes short- and long-term outcome in a national patient cohort and aims to identify prognostic factors. METHODS: All patients treated with CRS-HIPEC for non-appendiceal PM-CRC in Norway 2004-2013 were included (n = 119), and outcome and potential prognostic factors were examined using survival- and ROC-curve analysis...

OBJECTIVE: To study the effects of COX-2 on colonic surgical wound healing. BACKGROUND: Cyclooxygenase-2 (COX-2) is a key enzyme in gastrointestinal homeostasis. COX-2 inhibitors have been associated with colonic anastomotic leakage. METHODS: Wildtype, COX-2 knockout and COX-2 heterozygous mice were subjected to a model of colonic anastomotic leakage, and were treated with vehicle, diclofenac, or prostaglandin E2 (PGE2), the most important COX-2 product in the intestine...

More than half of human colorectal cancers (CRCs) carry either KRAS or BRAF mutations and are often refractory to approved targeted therapies. We found that cultured human CRC cells harboring KRAS or BRAF mutations are selectively killed when exposed to high levels of vitamin C. This effect is due to increased uptake of the oxidized form of vitamin C, dehydroascorbate (DHA), via the GLUT1 glucose transporter. Increased DHA uptake causes oxidative stress as intracellular DHA is reduced to vitamin C, depleting glutathione...

OBJECTIVES: To clarify whether bowel preparation use or its individual components [mechanical bowel preparation (MBP)/oral antibiotics] impact specific outcomes after colorectal surgery. METHODS: National Surgical Quality Improvement Program-targeted colectomy data initiated in 2012 capture information on the use/type of bowel preparation and colorectal-specific complications. For patients undergoing elective colorectal resection, the impact of preoperative MBP and antibiotics (MBP+/ABX+), MBP alone (MBP+/ABX-), and no bowel preparation (no-prep) on outcomes, particularly anastomotic leak, surgical site infection (SSI), and ileus, were evaluated using unadjusted/adjusted logistic regression analysis...

Substantial improvements have been made in the management of metastatic colorectal cancer over the last two decades. The overall survival of patients diagnosed with unresectable metastatic colorectal cancer has increased from approximately 1 year during the era of fluoropyrimidine monotherapy to more than 30 months with the integration of multiple cytotoxic agents and targeted therapies. More effective therapeutic combinations have increased the rate of curative-intent surgical resections, resulting in median survival in this subgroup that exceed 5 years...

OBJECTIVE: To determine the relationship between oral antibiotic bowel preparation (OABP) and surgical site infection (SSI) rates in a national colectomy cohort. BACKGROUND: OABP for elective colorectal surgery has fallen out of favor. Large cohort studies show that OABP is associated with a 50% reduction in SSI after colectomy. METHODS: A retrospective analysis of the National Surgical Quality Improvement Program colectomy cohort from 2011 to 2012 was performed to examine the association between use of OABP and outcomes of SSI, length of stay (LOS), and readmission after elective colectomy...

IMPORTANCE: Nonsteroidal anti-inflammatory drugs (NSAIDs) have many physiologic effects and are being used more commonly to treat postoperative pain, but recent small studies have suggested that NSAIDs may impair anastomotic healing in the gastrointestinal tract. OBJECTIVE: To evaluate the relationship between postoperative NSAID administration and anastomotic complications. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study of 13,082 patients undergoing bariatric or colorectal surgery at 47 hospitals in Washington State from January 1, 2006, through December 31, 2010, using data from the Surgical Care and Outcomes Assessment Program linked to the Washington State Comprehensive Abstract Reporting System...

OBJECTIVE: Compare the feasibility and patient tolerance to either a clear fluid (CF) or low residue diet (LRD) started on postoperative day (POD) 1 after elective colorectal surgery. BACKGROUND: Diet advancement after surgery traditionally starts gradually with liquids, on the basis of fears that early solid intake may increase nausea, vomiting, and overall complications. A randomized controlled trial comparing LRD and CF on POD 1 was performed. METHODS: 111 elective colorectal surgery patients were randomized to CF (n = 57) or LRD (n = 54)...
