Human intestinal stromal cells promote homeostasis in normal mucosa but inflammation in Crohn's disease in a retinoic acid-deficient manner.

Intestinal stromal cells (SCs), which synthesize the extracellular matrix that gives the mucosa its structure, are newly appreciated to play a role in mucosal inflammation. Here we show that human intestinal vimentin+CD90+SMA- SCs synthesize retinoic acid (RA) at levels equivalent to intestinal epithelial cells, a function in the human intestine previously attributed exclusively to epithelial cells. Crohn's disease SCs (Crohn's SCs), however, synthesized markedly less RA than SCs from healthy intestine (Normal SCs). We also show that microbe-stimulated Crohn's SCs, which are more inflammatory than stimulated Normal SCs, induced less RA-regulated differentiation of mucosal DCS (circulating pre-DCs and monocyte-derived DCs), leading to the generation of more potent inflammatory IFN-γhi/IL-17hi T cells than Normal SCs. Explaining these results, Crohn's SCs expressed more DHRS3, a retinaldehyde reductase that inhibits retinol conversion to retinal, and thus synthesized less RA than Normal SCs. These findings uncover a microbe-SC-DC crosstalk in which luminal microbes induce Crohn's disease SCs to initiate and perpetuate inflammation through impaired synthesis of RA.

Disparities in Perioperative Use of Patient Engagement Technologies - Not All Use is Equal.

OBJECTIVE: To determine the association of patient-level characteristics on the use of a patient engagement technology during the perioperative period. SUMMARY OF BACKGROUND DATA: As implementation of patient engagement technologies continues to grow, it remains unclear who uses, and not uses, these technologies. Existing literature suggests significant disparities in usage of other technologies by patient age, race, sex, and geographic location, however, have yet to characterize patient usage of patient engagement technologies. METHODS: This is a retrospective cohort study of patients undergoing elective surgery by a colorectal surgeon between January 2018 and March 2020 who enrolled in a patient engagement technology at a single institution. Patients enrolled received educational content, healthcare reminders, patient reported outcome (PRO) surveys, and health checks preoperatively, in-hospital, and for 30-days postdischarge. The primary outcome was patient activation of the patient engagement technology. Secondary outcomes were completion of at least 1 PRO survey, 1 in-hospital health check, and 1 postdischarge health check. RESULTS: Of 549 patients who enrolled in the patient engagement technology, 473 (86.2%) activated. On multivariable stepwise regression, female patients [odds ratio (OR) 2.4, confidence interval (CI) 1.4-4.0, P = 0.001] and privately insured patients (OR 2.0, CI 1.1-3.8, P = 0.03) were more likely to activate. Black patients were less likely to activate (OR 0.5, CI 0.3-0.9, P = 0.02). Once activated, privately insured patients were more likely to complete PRO surveys (OR 2.3, CI 1.2-4.3, P = 0.01), in-hospital health checks (OR 2.4, CI 1.4-4.1, P = 0.002), and postdischarge health checks (OR 1.9, CI 1.1 -3.3, P < 0.001) than uninsured patients. Black patients were less likely to complete PRO surveys (OR 0.4, CI 0.3-0.7, P = 0.001) and in-hospital health checks (OR 0.6, CI 0.4-0.9, P = 0.03) than White patients. CONCLUSIONS: Use of a patient engagement technology in the perioperative period differs significantly by sex, race/ethnicity, and insurance status. These technologies may not be used equally by all patients, which should be considered during implementation of interventions to improve surgical outcomes.

Robotic Anastomotic Technique.

The first robotic colectomy was performed 20 years ago. Since that time, the robotic surgery platform has made significant advancements and become increasingly prevalent in colorectal surgery. The da Vinci Xi system (Intuitive Surgical, Sunnyvale, CA) and technology such as integrated table motion has facilitated multiquadrant procedures. Intracorporeal anastomoses (ICAs) have proven benefit in the literature, including decreased length of stay, decreased narcotic requirements, and lower rate of postoperative wound infections and hernias. Additional studies have shown a lower conversion to open rate in robotic surgery compared with laparoscopy. In this article, we will describe techniques for creation of robotic ICAs.

Robotic-assisted versus laparoscopic rectal surgery in obese and morbidly obese patients: ACS-NSQIP analysis.

Laparoscopic rectal surgery within the confines of a narrow pelvis may be associated with a high rate of open conversion. In the obese and morbidly obese patient, the complexity of laparoscopic surgery increases substantially. Robotic technology is known to reduce the risk of conversion, but it is unclear if it can overcome the technical challenges associated with obesity. The ACS NSQIP database was used to identify obese patients who underwent elective laparoscopic or robotic-assisted rectal resection from 2015 to 2016. Obesity was defined as a body mass index (BMI) greater than or equal to 30 kg/m2. Morbid obesity was defined as a BMI greater than or equal to 35 kg/m2. The primary outcome was unplanned conversions to open. Other outcomes measures assessed included anastomotic leak, operative time, surgical site infections, length of hospital stay, readmissions and mortality. Statistical analyses were performed using SPSS 22.0 (IBM SPSS, USA). 1490 patients had robotic-assisted and 4967 patients had laparoscopic rectal resections between 2015 and 2016. Of those patients, 561 obese patients had robotic-assisted rectal resections and 1824 patients underwent laparoscopic rectal surgery. In the obese cohort, the rate of unplanned conversion to open in the robotic group was 14% compared to 24% in the laparoscopic group (P < 0.0001). Median operative time was significantly longer in the robotic group (248 min vs. 215 min, P < 0.0001). There was no difference in anastomotic leak or systemic sepsis between the laparoscopic and robotic rectal surgery groups. In morbidly obese patients (BMI ≥ 35 kg/m2), the rate of unplanned conversion to open in the robotic group was 19% compared to 26% in the laparoscopic group (P < 0.027). There was no difference in anastomotic leak, systemic sepsis or surgical site infection rates between robotic and laparoscopic rectal resection. Multivariate analysis showed that robotic-assisted surgery was associated with fewer unplanned conversions to open (OR 0.28, P < 0.0001). Robotic-assisted surgery is associated with a decreased risk of conversion to open in obese and morbidly obese patients when compared to conventional laparoscopic surgery. However, robotic surgery was associated with longer operative time and despite improvement in the rate of conversion to open, there was no difference in complications or length of stay. Our findings are limited by the retrospective non-randomised nature of the study, demographic differences between the two groups, and the likely difference in surgeon experience between the two groups. Large randomised controlled studies are needed to further explore the role of robotic rectal surgery in obese and morbidly obese patients.

Characterizing the impact of verbal communication and health literacy in the patient-surgeon encounter.

BACKGROUND: Patients with limited health literacy (HL) have difficulty understanding written/verbal information. The quality of verbal communication is not well understood. Therefore, our aim was to characterize patient-surgeon conversations and identify opportunities for improvement. METHODS: New colorectal patient-surgeon encounters were audio-recorded and transcribed. HL was measured. Primary outcomes were rates-of-speech, understandability of words, patient-reported understanding, and usage of medical jargon/statistics. Secondary outcomes included length-of-visit (LOV), conversation possession time, patient-surgeon exchanges, and speech interruptions. RESULTS: Significant variations existed between surgeons in rates-of-speech and understandability of words (p < 0.05). Faster rates-of-speech were associated with significantly less understandable words (p < 0.05). Patient-reported understanding varied by HL and by surgeon. Conversation possession time and usage of medical jargon/statistics varied significantly by surgeon (p < 0.05) in addition to patient-surgeon exchanges and interruptions. Patients with limited HL had shorter LOV. CONCLUSIONS: Significant variations exist in how surgeons talk to patients. Opportunities to improve verbal communication include slowing speech and using more understandable words.

Intracorporeal and extracorporeal anastomosis for robotic-assisted and laparoscopic right colectomy: short-term outcomes of a multi-center prospective trial.

BACKGROUND: Studies to date show contrasting conclusions when comparing intracorporeal and extracorporeal anastomoses for minimally invasive right colectomy. Large multi-center prospective studies comparing perioperative outcomes between these two techniques are needed. The purpose of this study was to compare intracorporeal and extracorporeal anastomoses outcomes for robotic assisted and laparoscopic right colectomy. METHODS: Multi-center, prospective, observational study of patients with malignant or benign disease scheduled for laparoscopic or robotic-assisted right colectomy. Outcomes included conversion rate, gastrointestinal recovery, and complication rates. RESULTS: There were 280 patients: 156 in the robotic assisted and laparoscopic intracorporeal anastomosis (IA) group and 124 in the robotic assisted and laparoscopic extracorporeal anastomosis (EA) group. The EA group was older (mean age 67 vs. 65 years, p = 0.05) and had fewer white (81% vs. 90%, p = 0.05) and Hispanic (2% vs. 12%, p = 0.003) patients. The EA group had more patients with comorbidities (82% vs. 72%, p = 0.04) while there was no significant difference in individual comorbidities between groups. IA was associated with fewer conversions to open and hand-assisted laparoscopic approaches (p = 0.007), shorter extraction site incision length (4.9 vs. 6.2 cm; p ≤ 0.0001), and longer operative time (156.9 vs. 118.2 min). Postoperatively, patients with IA had shorter time to first flatus, (1.5 vs. 1.8 days; p ≤ 0.0001), time to first bowel movement (1.6 vs. 2.0 days; p = 0.0005), time to resume soft/regular diet (29.0 vs. 37.5 h; p = 0.0014), and shorter length of hospital stay (median, 3 vs. 4 days; p ≤ 0.0001). Postoperative complication rates were comparable between groups. CONCLUSION: In this prospective, multi-center study of minimally invasive right colectomy across 20 institutions, IA was associated with significant improvements in conversion rates, return of bowel function, and shorter hospital stay, as well as significantly longer operative times compared to EA. These data validate current efforts to increase training and adoption of the IA technique for minimally invasive right colectomy.

Multidisciplinary clinics for colorectal cancer may not provide more efficient coordination of care.

BACKGROUND: This retrospective study compares a multidisciplinary clinic (MDC) to standard care for time to treatment of colorectal cancer. METHODS: We queried our institutional ACS-NSQIP database for patients undergoing surgery for colorectal cancer from 2017 to 2020. Patients were stratified by initial clinic visit (MDC vs control). Primary endpoint was the time to start treatment (TST), either neoadjuvant therapy or surgery, from the date of diagnosis by colonoscopy. RESULTS: A total of 405 patients were evaluated (115 MDC, 290 Control). TST from diagnosis was not significantly shorter for the MDC cohort (MDC 30 days, Control 37 days; p = 0.07) even when stratified by type of initial treatment of neoadjuvant therapy (MDC 30, Control 34 days; p = 0.28) or surgery (MDC 32.5 days, Control 38 days; p = 0.35). CONCLUSION: Implementation of an MDC provides insignificant reduction in delay to start treatment for colorectal cancer patients as compared to standard care colorectal surgery clinics. CLASSIFICATION: Colorectal.

Robotic Surgery in Crohn's Disease.

Surgery for Crohn's disease presents unique challenges secondary to the inflammatory nature of the disease. While a minimally invasive approach to colorectal surgery has consistently been associated with better patient outcomes, adoption of laparoscopy in Crohn's disease has been limited due to these challenges. Robotic assisted surgery has the potential to overcome these challenges and allow more complex patients to undergo a minimally invasive operation. Here we describe our approach to robotic assisted surgery for terminal ileal Crohn's disease.

Racial disparities exist in surgical outcomes for patients with inflammatory bowel disease.

BACKGROUND: Racial disparities in surgical outcomes exist for Black patients with IBD compared to White patients. However, previous studies fail to include other racial/ethnic populations. We hypothesized these disparities exist for Hispanic and Asian patients. METHODS: This is a retrospective cohort study of patients undergoing surgery for IBD using the American College of Surgeons National Surgical Quality Improvement Program (ACS- NSQIP) database (2005-2017). Bivariate comparisons and adjusted multivariable regressions were performed to evaluate associations between race and outcomes. RESULTS: Of 23,901 patients with IBD, the racial/ethnic makeup were: 88.7% White, 7.6% Black, 2.4% Hispanic and 1.4% Asian. Overall mean LOS was 8 days (SD 8.2) and significantly varied between groups (8d for White, 10d for Black, 8.5d for Hispanic, and 11.1d for Asian; p < 0.001). Hispanic patients had the highest odds of readmission (OR: 1.4; 95% CI 1.1-1.8). Black patients had increased odds of renal insufficiency (OR: 1.8; 95% CI 1.1-2.9), bleeding requiring transfusions (OR: 1.7; 95% CI 1.4-1.9), and sepsis (OR: 1.7; 95% CI 1.4-2.02) compared to White patients. CONCLUSIONS: Racial disparities exist among IBD patients undergoing surgery. Black, Hispanic and Asian IBD patients experience major disparities in post-operative complications, readmissions and LOS, respectively, when compared to White patients with IBD. Future research is needed to better understand the mechanisms of these disparities including evaluation of social determinants of health.

The impact of an enhanced recovery program (ERP) on the costs of colorectal surgery.

BACKGROUND: Enhanced Recovery Programs (ERPs) benefit patients but their effects on healthcare costs remain unclear. This study aimed to investigate the costs associated with a colorectal ERP in a large academic health system. METHODS: Patients who underwent colorectal surgery from 2012 to 2014 (pre-ERP) and 2015-2017 (ERP) were propensity score matched based on patient and operative-level characteristics. Primary outcomes were median variable, fixed, and total costs. Secondary outcomes included length-of-stay (LOS), readmissions, and postoperative complications (POCs). RESULTS: 616 surgical cases were included. Patient and operative-level characteristics were similar between the cohorts. Variable costs were $1028 less with ERP. ERP showed savings in nursing, surgery, anesthesiology, pharmacy, and laboratory costs, but had higher fixed costs. Total costs between the two groups were similar. ERP patients had significantly shorter LOS (-1 day, p < 0.01), but similar 30-day readmission rates and overall POCs. CONCLUSIONS: Implementation of an ERP for colorectal surgery was associated with lower variable costs compared to pre-ERP.

Assessment of a circular powered stapler for creation of anastomosis in left-sided colorectal surgery: A prospective cohort study.

BACKGROUND: Circular staplers perform a critical function for creation of anastomoses in colorectal surgeries. Powered stapling systems allow for reduced force required by surgeons to fire the device and may provide advantages for creating a secure anastomosis. The objective of this study was to evaluate the clinical performance of a novel circular powered stapler in a post-market setting, during left-sided colectomy procedures. MATERIALS AND METHODS: Consecutive subjects underwent left-sided colorectal resections that included anastomosis performed with the ECHELON CIRCULAR™ Powered Stapler (ECP). The primary endpoint was the frequency in which a stapler performance issue was observed. Secondary endpoints included evaluation of ease of use of the device via a surgeon satisfaction questionnaire, and monitoring/recording of procedure-related adverse events (AEs). RESULTS: A total of 168 anastomoses were performed with the ECP. Surgical approaches included robotic-assisted (n = 74, 44.0%), laparoscopic (n = 71, 42.3%), open (n = 20, 11.9%), and hand-assisted minimally invasive (n = 3, 1.8%) procedures. There were 22 occurrences of device performance issues in 20 (11.9%) subjects during surgery. No positive intraoperative leak tests were observed, and only 1 issue was related to a procedure-related AE or surgical complication, which was an instance of incomplete surgical donut necessitating re-anastomosis. Postoperative anastomotic leaks were experienced in 4 (2.4%) subjects. Clavien-Dindo classification of all AEs indicated that 92.0% were Grades I or II. Participating surgeons rated the ECP as easier to use compared to previously used manual circular staplers in 85.7% of procedures. CONCLUSION: The circular powered stapler exhibited few clinically relevant performance issues, an overall favorable safety profile, and ease of use for creation of left-sided colon anastomoses.

Low Health Literacy Exists in the Inflammatory Bowel Disease (IBD) Population and Is Disproportionately Prevalent in Older African Americans.

BACKGROUND: Low health literacy is common in general populations, but its prevalence in the inflammatory bowel disease (IBD) population is unclear. The objective of this study was to assess the prevalence of low health literacy in a diverse IBD population and to identify risk factors for low health literacy. METHODS: Adult patients with IBD at a single institution from November 2017 to May 2018 were assessed for health literacy using the Newest Vital Sign (NVS). Demographic and socioeconomic data were also collected. Primary outcome was the prevalence of low health literacy. Secondary outcomes were length-of-stay (LOS) and 30-day readmissions after surgical encounters. Bivariate comparisons and multivariable regression were used for analyses. RESULTS: Of 175 IBD patients, 59% were women, 23% were African Americans, 91% had Crohn disease, and mean age was 46 years (SD = 16.7). The overall prevalence of low health literacy was 24%. Compared to white IBD patients, African Americans had significantly higher prevalence of low health literacy (47.5% vs 17.0%, P < 0.05). On multivariable analysis, low health literacy was associated with older age and African American race (P < 0.05). Of 83 IBD patients undergoing abdominal surgery, mean postoperative LOS was 5.5 days and readmission rate was 28.9%. There was no significant difference between LOS and readmissions rates by health literacy levels. CONCLUSIONS: Low health literacy is present in IBD populations and more common among older African Americans. Opportunities exist for providing more health literacy-sensitive care in IBD to address disparities and to benefit those with low health literacy.

The Association of Enhanced Recovery Pathway and Acute Kidney Injury in Patients Undergoing Colorectal Surgery.

BACKGROUND: Acute kidney injury is associated with increased postoperative length of hospital stay and increases the risk of postoperative mortality. The association between the development of postoperative acute kidney injury and the implementation of an enhanced recovery after surgery protocol remains unclear. OBJECTIVE: This study aimed to examine the relationship between the implementation of an enhanced recovery pathway and the development of postoperative acute kidney injury. DESIGN: In this retrospective cohort study, a prospectively maintained database of patients who underwent elective colorectal surgery in an enhanced recovery pathway were compared to a hospital historical National Surgical Quality Improvement Program colorectal registry of patients. SETTINGS: This study was conducted at the University of Alabama at Birmingham, a tertiary referral center. PATIENTS: A total of 1052 patients undergoing elective colorectal surgery from 2012 through 2016 were included. MAIN OUTCOME MEASURES: The development of postoperative acute kidney injury was the primary outcome measured. RESULTS: Patients undergoing an enhanced recovery pathway had significantly greater rates of postoperative acute kidney injury than patients not undergoing an enhanced recovery pathway (13.64% vs 7.08%; p < 0.01). Our adjusted model indicated that patients who underwent an enhanced recovery pathway (OR, 2.31; 95% CI, 1.48-3.59; p < 0.01) had an increased risk of acute kidney injury. Patients who developed acute kidney injury in the enhanced recovery cohort had a significantly longer median length of stay than those who did not (median 4 (interquartile range, 4-9) vs 3 (interquartile range, 2-5) days; p=0.04). LIMITATIONS: This study did not utilize urine output as a modality for detecting acute kidney injury. Data are limited to a sample of patients from a large academic medical center participating in the National Surgical Quality Improvement Program. Interventions or programs in place at our institution that aimed at infection reduction or other initiatives with the goal of improving quality were not accounted for in this study. CONCLUSION: The implementation of an enhanced recovery after surgery protocol is independently associated with the development of postoperative acute kidney injury.See Video Abstract at http://links.lww.com/DCR/B69.

Risk of Surgical Site Infection (SSI) following Colorectal Resection Is Higher in Patients With Disseminated Cancer: An NCCN Member Cohort Study.

BACKGROUNDSurgical site infections (SSIs) following colorectal surgery (CRS) are among the most common healthcare-associated infections (HAIs). Reduction in colorectal SSI rates is an important goal for surgical quality improvement.OBJECTIVETo examine rates of SSI in patients with and without cancer and to identify potential predictors of SSI risk following CRSDESIGNAmerican College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data files for 2011-2013 from a sample of 12 National Comprehensive Cancer Network (NCCN) member institutions were combined. Pooled SSI rates for colorectal procedures were calculated and risk was evaluated. The independent importance of potential risk factors was assessed using logistic regression.SETTINGMulticenter studyPARTICIPANTSOf 22 invited NCCN centers, 11 participated (50%). Colorectal procedures were selected by principal procedure current procedural technology (CPT) code. Cancer was defined by International Classification of Disease, Ninth Revision, Clinical Modification (ICD-9-CM) codes.MAIN OUTCOMEThe primary outcome of interest was 30-day SSI rate.RESULTSA total of 652 SSIs (11.06%) were reported among 5,893 CRSs. Risk of SSI was similar for patients with and without cancer. Among CRS patients with underlying cancer, disseminated cancer (SSI rate, 17.5%; odds ratio [OR], 1.66; 95% confidence interval [CI], 1.23-2.26; P=.001), ASA score ≥3 (OR, 1.41; 95% CI, 1.09-1.83; P=.001), chronic obstructive pulmonary disease (COPD; OR, 1.6; 95% CI, 1.06-2.53; P=.02), and longer duration of procedure were associated with development of SSI.CONCLUSIONSPatients with disseminated cancer are at a higher risk for developing SSI. ASA score >3, COPD, and longer duration of surgery predict SSI risk. Disseminated cancer should be further evaluated by the Centers for Disease Control and Prevention (CDC) in generating risk-adjusted outcomes.Infect Control Hosp Epidemiol 2018;39:555-562.

Racial Disparities After Stoma Construction Exist in Time to Closure After 1 Year but Not in Overall Stoma Reversal Rates.

INTRODUCTION: Conflicting data exist on racial disparities in stoma reversal (SR) rates. Our aim was to investigate the role of race in SR rates, and time to closure, in a longitudinal, racially diverse database. METHODS: All adult patients (>18 years) who received an ileostomy or colostomy from 1999 to 2016 at a single institution were identified. Primary outcomes were SR rates and time to closure. Failure to reverse and time to closure was modeled using Cox regression. Kaplan-Meier survival curves, stratified by race, were generated for time to closure and hazard ratios (HRs) calculated. RESULTS: Of 770 patients with stomas, 65.6% of patients underwent SR; 76.6% were white and 23.4% were black. On adjusted analysis, race did not predict overall SR rates or time to closure if performed less than 1 year. Instead, significant predictors for failure in SR included age, insurance status, end colostomy/ileostomy, and loop colostomy (p < 0.05). Predictors of delay in time to closure included insurance, end colostomy/ileostomy, and loop colostomy (p < 0.05). In patients who underwent reversal after 1 year, black race was an independent predictor of time to closure (HR 0.21, 95% CI 0.07-0.63, p < 0.05). CONCLUSION: SR rates were equal between black and white patients. Disparities in time to closure existed only for black patients if reversed more than 1 year after index stoma construction. While equitable outcomes were achieved for most patients, further investigation is necessary to understand stoma disparities after 1 year.

Enhanced Recovery After Surgery (ERAS) Eliminates Racial Disparities in Postoperative Length of Stay After Colorectal Surgery.

OBJECTIVE: To investigate the effects of enhanced recovery after surgery (ERAS) on racial disparities in postoperative length of stay (pLOS) after colorectal surgery. BACKGROUND: Racial disparities in surgical outcomes exist. We hypothesized that ERAS would reduce disparities in pLOS between black and white patients. METHODS: Patients undergoing ERAS in 2015 were 1:1 matched by race/ethnicity, age, sex, and procedure to a pre-ERAS group from 2010 to 2014. After stratification by race/ethnicity, expected pLOS was calculated using the American College of Surgeons National Surgical Quality Improvement Project Risk Calculator. Primary outcome was the observed pLOS and observed-to-expected difference in pLOS. Secondary outcomes were National Surgical Quality Improvement Project postoperative complications including 30-day readmissions and mortality. Adjusted sensitivity analyses on pLOS were also performed. RESULTS: Of 420 patients (210 ERAS and 210 pre-ERAS) examined, 28.3% were black. Black and white patients were similar in age, body mass index, sex, American Anesthesia Association class, and minimally invasive approaches. Within the pre-ERAS group, black patients stayed a mean of 2.7 days longer than expected compared with white patients (P < 0.05). Overall, ERAS patients had a significantly shorter pLOS (5.7 vs 8 days) and observed-to-expected difference (-0.7 vs 1.4 days) compared with pre-ERAS patients (P < 0.01). In the ERAS group, disparities in pLOS were reduced with no differences in readmissions or mortality between black and white patients. On sensitivity analyses, race/ethnicity remained a significant predictor of pLOS among pre-ERAS patients, but not for ERAS patients. CONCLUSIONS: ERAS eliminated racial differences in pLOS between black and white patients undergoing colorectal surgery. Reduced pLOS occurred without increases in mortality, readmissions, and most postoperative complications. ERAS may provide a practical approach to reducing disparities in surgical outcomes.

Evaluation, Diagnosis, and Medical Management of Rectal Prolapse.

Full-thickness rectal prolapse, or procidentia, is the passage of the full-thickness wall of the rectum beyond the anal sphincters. This condition results in pain and fecal incontinence which greatly impairs the quality of life of those afflicted. It is associated with several anatomic abnormalities, including decreased anal sphincter tone, levator muscle diastasis, and a deep anterior cul-de-sac. The diagnosis of rectal prolapse is made based on physical examination, although several other modalities are used to provide additional information about the patients' condition. While medical management of rectal prolapse can be effective in some cases, the mainstay of management of rectal prolapse is surgical correction.

Genetic/Familial High-Risk Assessment: Colorectal Version 1.2016, NCCN Clinical Practice Guidelines in Oncology.

This is a focused update highlighting the most current NCCN Guidelines for diagnosis and management of Lynch syndrome. Lynch syndrome is the most common cause of hereditary colorectal cancer, usually resulting from a germline mutation in 1 of 4 DNA mismatch repair genes (MLH1, MSH2, MSH6, or PMS2), or deletions in the EPCAM promoter. Patients with Lynch syndrome are at an increased lifetime risk, compared with the general population, for colorectal cancer, endometrial cancer, and other cancers, including of the stomach and ovary. As of 2016, the panel recommends screening all patients with colorectal cancer for Lynch syndrome and provides recommendations for surveillance for early detection and prevention of Lynch syndrome-associated cancers.

Understanding the Value of Both Laparoscopic and Robotic Approaches Compared to the Open Approach in Colorectal Surgery.

INTRO: Although the use of laparoscopy has significantly increased in colorectal procedures, robotic surgery may enable additional cases to be performed using a minimally invasive approach. We separately evaluated the value of laparoscopic and robotic colorectal procedures compared to the open approach. METHODS: Patients undergoing nonemergent colorectal operations from 2010 to 2013 with National Surgical Quality Improvement Project data were identified. Robotic and laparoscopic procedures were separately matched (1:1) to open cases. Outcomes included 30-day composite morbidity, length of stay, operative time, and inpatient costs. Frequently used intraoperative disposable items were categorized, and significant cost contributors were identified by surgical approach. Statistical differences were determined with Chi-square and Wilcoxon signed-rank tests. RESULTS: Both laparoscopic (n = 67) and robotic (n = 45) approaches were associated with decreased composite morbidity compared to matched open cases (lap vs. open: 22.4% vs. 49.2%, P < .01; robotic vs. open: 6.7% vs. 33.3%, P < .01). Median length of stay was significantly shorter for both laparoscopic and robotic compared to open surgery (lap vs. open: 5 vs. 7 days, P < .01; robotic vs. open: 5 vs. 7 days, P < .01). Median hospital costs were similar between laparoscopic and open surgery ($13,319 vs. $14,039; P = .80) and robotic and open surgery ($13,778 vs. $13,629; P = .48). CONCLUSION: These findings illustrate the value for both laparoscopic and robotic approaches to colorectal surgery compared to the open approach in terms of short-term outcomes and inpatient costs. Advanced intraoperative disposable items such as cutting staplers and energy devices are important targets for additional cost containment.
