IMPORTANCE Enhanced recovery after surgery (ERAS) colorectal programs have shown to be successful at reducing length of stay in many international and academic centers; however, their efficacy in a community hospital setting remains unclear. OBJECTIVE To determine if favorable results could be reproduced in a community hospital setting using our ERAS program, which was developed using core ERAS guidelines with the goal of accelerated recovery while also addressing other important outcomes affecting patient experience and safety. DESIGN, SETTING, AND PARTICIPANTS Prospective study of ERAS program, a multidisciplinary effort involving anesthesia, preadmission staff, nursing, and surgery staff at a community hospital. The program was initiated in 2010 and was in full practice by 2011. We assessed practice patterns and patient outcomes for all elective colon and rectal resection cases performed in 2009 (prior to ERAS implementation), 2011, and 2012. MAIN OUTCOMES AND MEASURES Laparoscopic approach, narcotic use, length of stay, 30-day readmission, ileus (defined as reinsertion of nasogastric tube), and intra-abdominal infection and association between colorectal cancer (CRC) diagnosis and these outcomes. RESULTS From 2009 to 2012, the use of laparoscopy increased from 57.4% to 88.8% (P < .001). Length of stay decreased significantly (6.7 days vs 3.7 days, P < .001), without an increase in 30-day readmission rate (17.6% vs 12.5%, P = .49). Use of patient-controlled narcotic analgesia and duration of use decreased (63.2% of patients vs 15%, P < .001; 67.8 hours vs 47.1 hours, P = .02). Ileus rate decreased from 13.2% to 2.5% (P = .02). Intra-abdominal infection decreased from 7.4% to 2.5% (P = .24). When comparing laparoscopic cases alone, similar results were observed. Following regression analysis, there were no statistically significant differences between CRC diagnosis and LOS, 30-day readmission rates, ileus, and intra-abdominal infection (all Ps > .05). Length of stay reductions resulted in an estimated cost savings of

4803 per patient (2012). CONCLUSIONS AND RELEVANCE Implementation of this patient care-directed enhanced recovery program is feasible in a community hospital setting, and it is associated with decreased LOS without increased readmission or morbidity, as well as significant decreases in narcotic use and cost. Improved outcomes are independent of the laparoscopic approach and CRC diagnosis.

In patients with colorectal cancer (CRC) that metastasizes to the liver, there are several key goals for improving outcomes including early detection, effective prognostic indicators of treatment response, and accurate identification of patients at high risk for recurrence. Although new therapeutic regimens developed over the past decade have increased survival, there is substantial room for improvement in selecting targeted treatment regimens for the patients who will derive the most benefit. Recently, there have been exciting developments in identifying high-risk patient cohorts, refinements in the understanding of systemic vs localized drug delivery to metastatic niches, liquid biomarker development, and dramatic advances in tumor immune therapy, all of which promise new and innovative approaches to tackling the problem of detecting and treating the metastatic spread of CRC to the liver. Our multidisciplinary group held a state-of-the-science symposium this past year to review advances in this rapidly evolving field. Herein, we present a discussion around the issues facing treatment of patients with CRC liver metastases, including the relationship of discrete gene signatures with prognosis. We also discuss the latest advances to maximize regional and systemic therapies aimed at decreasing intrahepatic recurrence, review recent insights into the tumor microenvironment, and summarize advances in noninvasive multimodal biomarkers for early detection of primary and recurrent disease. As we continue to advance clinically and technologically in the field of colorectal tumor biology, our goal should be continued refinement of predictive and prognostic studies to decrease recurrence after curative resection and minimize treatment toxicity to patients through a tailored multidisciplinary approach to cancer care.

BACKGROUND:The initial minimum operation for ulcerative colitis is a total abdominal colectomy. Healthy patients may undergo proctectomy at the same time; however, for ill patients, proctectomy is delayed. Since the introduction of biologic medications in 2005, ulcerative colitis medical management has changed dramatically. OBJECTIVE:We examined how operative management for ulcerative colitis has changed from the prebiologic to biologic eras. DESIGN:We conducted a retrospective review of data on patients with ulcerative colitis who were included in the Nationwide Inpatient Sample database. SETTINGS:This study was conducted at a single university. PATIENTS:A total of 1,547,852 patients with ulcerative colitis who were admitted to a US hospital from 1991 to 2011 were included in the study. MAIN OUTCOME MEASURES:We examined patients whose initial operation consisted of total abdominal colectomy without proctectomy versus a total proctocolectomy with or without a pouch. We also examined which operation was done at the time of the construction of an ileoanal pouch. Patients who underwent colectomy and pouch construction in the same hospitalization were compared with those who received pouch formation at a subsequent hospitalization. RESULTS:Ulcerative colitis–related admissions rose by 170% during the years examined, and the number of patients who required total abdominal colectomy increased by 44%. Total abdominal colectomy increased by 15%, as opposed to total proctocolectomy (p < 0.001). Pouch construction at a subsequent operation increased by 16% (p = 0.002). Since 2008, total abdominal colectomy has surpassed total proctocolectomy as the most common initial surgical intervention for ulcerative colitis. LIMITATIONS:The Nationwide Inpatient Sample is a retrospective database, and we were limited to examining the variables within it. CONCLUSIONS:Total abdominal colectomy is currently the most common initial operation for patients with ulcerative colitis, and an ileoanal pouch is more frequently constructed at a subsequent hospitalization. These trends coincide with the initiation of biologic treatments and may imply that patients are acutely ill at the time of initial operation. Alternately, there may be surgeon-perceived bias of increased surgical risk or a shift in care to specialized surgeons for pouch construction.

BACKGROUND: Underrepresentation of highly ranked women in academic surgery is recognized. OBJECTIVE: Our objective was to examine whether sex differences exist in faculty representation, academic rank, and publication productivity among colorectal faculty in fellowship programs. DESIGN: American Society of Colon and Rectal Surgeons fellowship program faculty were identified. Bibliometric data were obtained for each faculty member, including Hirsch index, the Hirsch index divided by research career duration, and number of publications. Linear mixed-effect regression models were constructed to determine the association between the Hirsch index and the Hirsch index divided by research career duration and sex, when controlling for institutional measures. A subset analysis of academic faculty examined the association between academic rank, sex, and Hirsch index and the Hirsch index divided by research career duration. SETTINGS: Colorectal fellowship programs, defined as academic, satellite-academic, and nonacademic, were evaluated. RESULTS: Three hundred fifty-eight faculty members were examined across 55 training programs; 22% (n = 77) were women and 78% (n = 281) were men. Sixty-one percent (n = 220) practiced in an academic setting, 23% (n = 84) in a satellite-academic setting, and 15% (n = 54) in a nonacademic setting. There was no difference in median number of publications between sexes (15 vs 10, p = 0.33); men, however, had longer careers (18 vs 11 years, p < 0.001). When controlling for confounders, there was no difference in the Hirsch index (p = 0.42) or the Hirsch index divided by research career duration (p = 0.73) between sexes. Academic rank was significantly associated with Hirsch index and the Hirsch index divided by research career duration (p < 0.001) after controlling for sex. LIMITATIONS: Our assessment of association between publication productivity and academic rank was only possible in the subset of academic faculty. In addition, this study is limited by its retrospective nature. CONCLUSIONS: We found no difference in median number of publications between men and women. When controlling for possible confounders, sex was not a significant predictor of a faculty member’s publication productivity, as measured by the Hirsch index or the Hirsch index divided by research career duration; academic rank, however, was.

PurposePelvic floor abnormalities often affect multiple organs. The incidence of concomitant uterine/vaginal prolapse with rectal prolapse is at least 38%. For these patients, addition of sacrocolpopexy to rectopexy may be appropriate. Our aim was to determine if addition of sacrocolpopexy to rectopexy increases the procedural morbidity over rectopexy alone.MethodsWe utilized the ACS-NSQIP database to examine female patients who underwent rectopexy from 2005 to 2014. We compared patients who had a combined procedure (sacrocolpopexy and rectopexy) to those who had rectopexy alone. Thirty-day morbidity was compared and a multivariable model constructed to determine predictors of complications.ResultsThree thousand six hundred patients underwent rectopexy; 3394 had rectopexy alone while 206 underwent a combined procedure with the addition of sacrocolpopexy. Use of the combined procedure increased significantly from 2.6 to 7.7%. Overall morbidity did not differ between groups (14.8% rectopexy alone vs. 13.6% combined procedure, p = 0.65). Significant predictors of morbidity included addition of resection to a rectopexy procedure, elevated BMI, smoking, wound class, and ASA class. After controlling for these and other patient factors, the addition of sacrocolpopexy to rectopexy did not increase overall morbidity (OR 1.00, p = 0.98).ConclusionsThere is no difference in operative morbidity when adding sacrocolpopexy to a rectopexy procedure. Despite a modest increase in utilization of combined procedures over time, the overall rate remains low. These findings support the practice of multidisciplinary evaluation of patients presenting with rectal prolapse, with the goal of offering concurrent surgical correction for all compartments affected by pelvic organ prolapse disorders.
