The NCCN has recently released its 2017 version 1.0 guideline for colorectal cancer. There are several updates from this new version guideline which are believed to change the current clinical practice. Update one, low-dose aspirin is recommended for patients with colorectal cancer after colectomy for secondary chemoprevention. Update two, biological agents are removed from the neoadjuvant treatment regimen for resectable metastatic colorectal cancer (mCRC). This update is based on lack of evidence to support benefits of biological agents including bevacizumab and cetuximab in the neoadjuvant setting...

INTRODUCTION: Lynch syndrome is the most common form of hereditary colorectal cancer, being also responsible for endometrial and other types of cancers. It is associated with germline mutations in DNA mismatch repair genes and microsatellite instability. MLH1 and MSH2 mutations have a "classical" Lynch syndrome phenotype, with MSH2 having a higher association with extracolonic cancer. MSH6 and PMS2 mutations have an atypical phenotype. Clinical expression is heterogeneous, with correlation between mismatch repair mutated gene and phenotypic patterns...

OBJECTIVES: Ileorectal anastomosis (IRA) affects bowel function, sexual function and reproduction less negatively than ileal pouch anal anastomosis (IPAA), the standard reconstruction after colectomy for ulcerative colitis (UC). In younger UC patients, IRA may have a role postponing pelvic surgery and IPAA. The aim of the present study was to investigate the survival of IPAA secondary to IRA compared to IPAA as primary reconstruction, as this has not previously been studied in UC. PATIENTS AND METHODS: All patients with UC diagnosis between 1960 and 2010 in Sweden were identified from the National Patient Registry...

BACKGROUND: Quantitative computed tomography (CT) assessment of visceral adiposity may be superior to body mass index (BMI) as a predictor of surgical morbidity. We sought to examine the association of CT measures of obesity and BMI with short-term postoperative outcomes in colon cancer patients. METHODS: In this retrospective study, 110 patients treated with colectomy for stage I-III colon cancer were classified as obese or non-obese by preoperative CT-based measures of adiposity or BMI [obese: BMI ≥ 30 kg/m(2), visceral fat area (VFA) to subcutaneous fat area ratio (V/S) ≥0...

A number of nontraumatic acute abdomen can result in peritonitis leading to sepsis. In emergent conditions, various procedures like segmentary colectomy and/or subtotal colectomy with anastomosis, Hartmann's procedure, transverse colectomy, and/or expandable metallic stent (SEMS) placement can be performed, considering the status of the patient and the facilitaties of the institution. In our study, we examined the cases diagnosed as acute abdomen without the history of trauma, which had lead to a procedure requiring colostomy...

Patients with perforated diverticulitis suffer high morbidity and mortality. For decades, sigmoid colectomy with colostomy (Hartman's procedure) has been considered the standard surgical management. Over the past several years, less-morbid alternatives have been advocated. Laparoscopic lavage showed promise in retrospective studies. However, recent prospective randomized clinical trials have suggested that outcomes may not be better compared with the Hartman's procedure. A critical analysis of the literature leads the authors to the conclusion that there is still a role for laparoscopic lavage in selected patients, as a bridge to elective colectomy or, in some cases, as definitive management...

A 50-year-old male smoker presented with a perforated colon cancer and underwent an extended right colectomy. Feculent peritonitis was treated with empiric antibiotics. Postoperatively he developed severe back pain and rising leukocytosis. Serial computed tomography revealed a rapidly expanding infrarenal aortic aneurysm. He was urgently treated with extra-anatomic bypasses and aortic resection. No organisms grew from the resected aortic wall. He was discharged in stable condition, and the ileostomy was reversed 9 months later...

This is a case of a 54-year-old gentleman who presented to an outside hospital emergency department with lower abdominal pain. Computed tomography imaging showed a small amount of intraperitoneal free air and cystic pneumatosis coli. He was admitted, managed conservatively with intravenous antibiotics, and then discharged home after his symptoms improved. Elective laparoscopic sigmoid colectomy was subsequently performed with intraoperative findings of partial sigmoid volvulus and extensive pneumatosis coli of the sigmoid colon...

The authors present a rare case of a 71-year-old man presenting with large bowel obstruction after attempted colonoscopy. The procedure was impossible to complete due to a tight sigmoid stricture and the patient presented with an acute abdomen the following day. He was managed conservatively and discharged before returning for an elective laparoscopic sigmoid colectomy. The potential differentials of an acute abdomen post-colonoscopy are discussed and the literature reviewed on this rare complication. Finally, the authors review whether there is pressure on endoscopists to 'complete' colonoscopies (by achieving caecal intubation) based on regulatory indices in quality, and how this might have to be disregarded in unfavourable circumstances...

BACKGROUND: Efficacy of azathioprine (AZA) in refractory ulcerative proctitis (UP) is unknown. METHODS: All patients treated with AZA for refractory UP in three referral centers between 2002 and 2012 were included. "Treatment success" in the long-term was defined as the absence of colectomy during follow-up, no need for anti-TNF during follow-up, no ongoing systemic steroids use, no adverse event leading to AZA withdrawal, and clinically quiescent disease at last follow-up...

BACKGROUND: Hospital readmission rates after surgery may represent an overall hospital effect or a combination of specialty and patient effects. We hypothesized that hospital readmission rates for procedures within specialties were more strongly correlated than rates across specialties within the same hospital. STUDY DESIGN: For general, orthopedic, and vascular specialties at Veterans Affairs hospitals during 2008-2014, 30-day risk-adjusted readmission rates were estimated for six high-volume procedures and each specialty...

BACKGROUND: The goals of this study were to characterize the variation in suboptimal lymph node examination for patients with colon cancer across individual surgeons, pathologists, and hospitals and to examine if this variation affects 5-year, disease-specific survival. METHODS: A retrospective cohort study was conducted by merging the New York State Cancer Registry with the Statewide Planning & Research Cooperative System, Medicaid, and Medicare claims to identify resections for stages I-III colon cancer from 2004-2011...

BACKGROUND: Pathologic lymph node staging is becoming a deficient method in the demanding molecular era. Nevertheless, the use of more sensitive molecular analysis for nodal staging is hampered by its high costs and extensive time requirements. Our aim is to take a step forward in colon cancer (CC) lymph node (LN) pathology diagnosis by proposing a feasible and efficient molecular method in routine practice using reverse transcription loop-mediated isothermal amplification (RT-LAMP). RESULTS: Molecular detection of tumor cytokeratin 19 (CK19) mRNA with RT-LAMP was performed in 3206 LNs from 188 CC patients using two methods: individual analysis of 1449 LNs from 102 patients (individual cohort), and pooled LN analysis of 1757 LNs from 86 patients (pooling cohort)...

A 71-year-old woman on aspirin presented for a distal pancreatectomy, splenectomy, and partial colectomy with a T8/9 epidural catheter placed preoperatively in 3 attempts. Prophylactic 5000 units of subcutaneous heparin were given before the procedure. After catheter removal on postoperative day 2, the patient developed transient bilateral lower extremity paralysis, with near complete recovery within 30 minutes. An urgent MRI revealed a T4-T8 epidural hematoma prompting an emergent T3-T8 laminectomy. This case presentation highlights the need for heightened awareness regarding complications related to neuraxial analgesia in patients receiving unfractionated heparin for thromboembolism prophylaxis with concurrent aspirin use...

BACKGROUND: Clostridium difficile infection (CDI) is a common complication of inflammatory bowel diseases (IBDs) and is associated with worse outcome. Variable rates of colectomy have been reported among IBD complicated by CDI. We conducted a systematic review and meta-analysis of studies to assess the association between CDI and colectomy among patients with IBD. METHODS: The literature was systematically searched using PubMed from inception through April 2016...

Biologic anti-tumor necrosis factor (TNF) drugs have demonstrated their efficacy for the treatment of ulcerative colitis. Nevertheless, some patients will not respond to this therapy or will develop loss of response. Leukapheresis is the main non-pharmacological therapy for some immune-mediated diseases. The aim of our study was to describe our experience with this therapy in ulcerative colitis patients after loss of response to anti-TNF treatment. Leukapheresis was indicated in four patients with left-sided or extensive colitis because of partial response to biological therapy or secondary loss of response to it...

Pedro Boal Carvalho, José Cotter
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized by periods of remission and periods of relapse. Patients often present with symptoms such as rectal bleeding, diarrhea and weight loss, and may require hospitalization and even colectomy. Long-term complications of UC include decreased quality of life and productivity and an increased risk of colorectal cancer. Mucosal healing (MH) has gained progressive importance in the management of UC patients. In this article, we review the endoscopic findings that define both mucosal injury and MH, and the strengths and limitations of the scoring systems currently available in clinical practice...

BACKGROUND: Although optimal medical management of acute severe ulcerative colitis (UC) is ill-defined, infliximab has become a standard of care. Accumulating evidence suggests an increased rate of infliximab clearance in patients with acute severe UC and a reduced colectomy rate with an intensified infliximab induction regimen. AIM: To assess the strength of the current evidence for the relationship between infliximab pharmacokinetics, dosing strategies and disease behaviour in patients with acute severe UC...

The rising popularity of episode-based payment models for surgery underscores the need to better understand the drivers of variability in spending on postacute care. Examining postacute care spending for fee-for-service Medicare beneficiaries after three common surgical procedures in the period 2009-12, we found that it varied widely between hospitals in the lowest versus highest spending quintiles for postacute care, with differences of 129 percent for total hip replacement, 103 percent for coronary artery bypass grafting (CABG), and 82 percent for colectomy...
