RESUMO
BACKGROUND: Enhanced Recovery After Surgery (ERAS) programs have become a mainstay of modern surgical care, and efforts to decrease postoperative opioid consumption have been increasingly employed. A previous study from our institution demonstrated that ERAS protocols decreased opioid use in the first 48 hours after surgery by 61%. In the present study, a lidocaine infusion was added for postoperative pain control. The aim was to analyze the differences in opioid requirements with and without this infusion in the first 48 hours after laparoscopic colectomy in ERAS patients. METHODS: Retrospective review of patients was conducted at an academically affiliated tertiary care hospital. The population included patients undergoing elective laparoscopic colon surgery enrolled in the ERAS program with the implementation of a lidocaine drip from June 2019 to October 2019, and compared to a previous patient cohort of ERAS patients evaluated without the lidocaine drip from September 2015 to May 2018. RESULTS: The primary endpoint was postoperative opioid use in the first 48 hours based on IV morphine milligram equivalents (MME). Secondary measures included type of surgery, age, BMI, prior abdominal surgery, and prior opioid use. Median MMEs were 6.0 in the lidocaine infusion group and 12.5 in the group without lidocaine, representing a 52% reduction (p < 0.001). DISCUSSION: This study demonstrates a significant reduction in post-op opioid use in ERAS patients who receive a lidocaine infusion after laparoscopic colectomy. Further studies should focus on measures to limit the treatment side effects in order to maximize the opioid-sparing benefits of this intervention.

BACKGROUND: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) Risk Calculator (RC) predicts postoperative outcomes using 19 risk factors, including operative acuity. Acuity is defined by the calculator as emergent or elective only. The objective of this study is to evaluate the RC's accuracy in urgent (nonelective/nonemergent) cases. METHODS: This is a retrospective review of the NSQIP data for patients who underwent urgent colectomies at a single tertiary care center over a 4-year period. Each urgent case was entered into the RC as both elective and emergent, and predicted outcomes were compared to actual postoperative outcomes. Receiver operating characteristic (ROC) curves were used when sufficient statistical power was present and the area under the curve (AUC) was calculated. RESULTS: A total of 301 urgent colectomy patients were evaluated, representing 19% of all colectomies performed at our institution during the study period. Of the 15 possible postoperative outcomes, the RC showed high predictive value only for mortality (AUC elective .8467; emergent .8451) and discharge to a nursing/rehabilitation facility (AUC elective .8089; emergent .8105). The RC showed no predictive value for 6 outcomes and the remainder lacked statistical power to draw conclusions. DISCUSSION: While the calculator predicted mortality and discharge to a nursing/rehabilitation facility, it did not accurately predict complications for urgent colectomies. Future versions of the calculator should focus on improving the predictive value by including urgent cases as a separate category.

There is variation in the responsiveness of locally advanced rectal cancer to neoadjuvant chemoradiation, from complete response to total resistance. This study compared genetic variation in rectal cancer patients who had a complete response to chemoradiation versus poor response, using tumor tissue samples sequenced with genomics analysis software. Rectal cancer patients treated with chemoradiation and proctectomy June 2006-March 2017 were grouped based on response to chemoradiation: those with no residual tumor after surgery (CR, complete responders, AJCC-CPR tumor grade 0, n = 8), and those with poor response (PR, AJCC-CPR tumor grade two or three on surgical resection, n = 8). We identified 195 variants in 83 genes in tissue specimens implicated in colorectal cancer biopathways. PR patients showed mutations in four genes not mutated in complete responders: KDM6A, ABL1, DAXX-ZBTB22, and KRAS. Ten genes were mutated only in the CR group, including ARID1A, PMS2, JAK1, CREBBP, MTOR, RB1, PRKAR1A, FBXW7, ATM C11orf65, and KMT2D, with specific discriminating variants noted in DMNT3A, KDM6A, MTOR, APC, and TP53. Although conclusions may be limited by small sample size in this pilot study, we identified multiple genetic variations in tumor DNA from rectal cancer patients who are poor responders to neoadjuvant chemoradiation, compared to complete responders.
RESUMO
OBJECTIVES: To determine the risk factors in diabetic patients that are associated with increased postcolectomy mortality and anastomotic leak. DESIGN: A prospectively acquired statewide database of patients who underwent colectomy was reviewed. Primary risk factors were diabetes mellitus, hyperglycemia (glucose level ≥ 140 mg/dL), steroid use, and emergency surgery. Categorical analysis, univariate logistic regression, and multivariate regression were used to evaluate the effects of these risk factors on outcomes. SETTING: Participating hospitals within the Michigan Surgical Quality Collaborative. PATIENTS: Database review of patients from hospitals within the Michigan Surgical Quality Collaborative. MAIN OUTCOME MEASURES: Anastomotic leak and 30- day mortality rate. RESULTS: Of 5123 patients, 153 (3.0%) had leaks and 153 (3.0%) died. Preoperative hyperglycemia occurred in 15.6% of patients, only 54% of whom were known to have diabetes. Multivariate analysis showed that the risk of leak for patients with and without diabetes increased only by preoperative steroid use (P<.05). Mortality among diabetic patients was associated with emergency surgery (P<.01) and anastomotic leak (P<.05); it was not associated with hyperglycemia. Mortality among nondiabetic patients was associated with hyperglycemia (P<.005). The presence of an anastomotic leak was associated with increased mortality among diabetic patients (26.3% vs 4.5%; P<.001) compared with nondiabetic patients (6.0% vs 2.5%; P<.05). CONCLUSIONS: The presence of diabetes did not have an effect on the presence of an anastomotic leak, but diabetic patients who had a leak had more than a 4-fold higher mortality compared with nondiabetic patients. Preoperative steroid use led to increased rates of anastomotic leak in diabetic patients. Mortality was associated with hyperglycemia for nondiabetic patients only. Improved screening may identify high-risk patients who would benefit from perioperative intervention.

PURPOSE: Evaluate the appropriateness of the 2008 United States Preventative Services Task Force screening recommendations for colorectal cancer. METHODS: Ages at diagnosis data were collected on patients with colorectal cancer from the William Beaumont Tumor Registry. The database identified 6,925 patients treated for colorectal cancer between January 1973 and December 2007. Patients were divided into 3 age groups at diagnosis categories (younger than 50 years old, those 50 to 75 years old, and those older than 75 years old) to evaluate whether there were changes in the age distribution, pathologic stage, or tumor location during the 35-year period. RESULTS: The percent of patients with colorectal cancer older than age 75 years increased from 29% to 40% (P < .0001). The combined percentage of patients younger than age 50 years and older than age 75 years has increased from 36% (1973-1978) to 49% (2003-2007). The combined percentages of stage III and IV disease in patients younger than 50 years and older than 75 years were 51% and 34%, respectively (P < .0001). Rectal or left-sided lesions occurred in 68%, 64%, and 50% of patients younger than 50 years old, those 50 to 75 years old, and those older than 75 years old, respectively (P < .0001). Right-sided lesions occurred in 22%, 25%, and 37% of those younger than 50 years old, those 50 to 75 years old, and those older than 75 years old, respectively (P < .0001). CONCLUSIONS: There has been a significant increase in the percentage of colorectal cancer patients older than age 75 years. Failing to screen patients younger than 50 years and older than the age of 75 years would miss 49% of patients treated at our institution from 2003 to 2007.

PURPOSE: Spasm of the internal sphincter plays a role in hemorrhoidal disease and may be a source of anal pain after hemorrhoid surgery. We have evaluated the effects of topical diltiazem, a calcium channel blocker, in reducing pain after hemorrhoidectomy. METHODS: After hemorrhoidectomy, 18 patients were randomly assigned to receive 2 percent diltiazem ointment (n = 9) or a placebo ointment (n = 9). Ointments were applied to the perianal region three times daily for seven days. Patients were prescribed hydrocodone bitartrate (Vicodin) to take as needed. The type and number of prescribed or nonprescribed medications taken during the postoperative period were recorded. Patients maintained a log to measure postoperative pain daily and perceived benefit of the ointment, using a Visual Analog Scale ranging from 0 to 10. Any postoperative morbidity noted during the follow-up period was recorded. RESULTS: Patients using the diltiazem ointment had significantly less pain and greater benefit than those in the placebo group throughout the first postoperative week. Postoperative pain scores in the placebo group averaged 8.8 +/- 1.2 early and diminished to 5.2 +/- 1.7 at the end of one week, compared to the diltiazem group of 5.2 +/- 2.4 early and 2.3 +/- 1.2 at the end of one week (P < 0.001, both time periods). Perceived benefit in the placebo group averaged 2.7 +/- 1.2 vs. 5.6 +/- 1.4 in the diltiazem group (P < 0.001). Total and daily narcotic use was higher in the placebo group, but this was not statistically significant (P = 0.13). No differences in the frequency of use of nonsteroidal anti-inflammatory drugs and acetaminophen were seen between the two groups, and there were no differences in morbidity between the two groups. CONCLUSIONS: Perianal application of 2 percent diltiazem ointment after hemorrhoidectomy significantly reduces postoperative pain and is perceived as beneficial, with no increase in associated morbidity. Patients using a placebo ointment tend to take more prescription narcotics for pain relief postoperatively, with a similar usage of nonsteroidal anti-inflammatory drugs and acetaminophen, although differences were not significant.
