Abstract
BACKGROUND Prolonged postoperative ileus (PPOI) contributes to morbidity and prolonged hospitalization. Prucalopride, a selective 5-hydroxytryptamine receptor agonist, may enhance bowel motility. This review assesses whether the perioperative use of prucalopride compared to placebo is associated with accelerated return of bowel function post gastrointestinal (GI) surgery. METHODS OVID, CENTRAL, and EMBASE were searched as of January 2024 to identify randomized controlled trials (RCTs) comparing prucalopride and placebo for prevention of PPOI in adult patients undergoing GI surgery. The primary outcomes were time to stool, time to flatus, and time to oral tolerance. The secondary outcomes were incidence of PPOI, length of stay (LOS), postoperative complications, adverse events, and overall costs. The Cochrane risk of bias tool for randomized trials and the Grading of Recommendations, Assessment, Development, and Evaluations framework were used. An inverse variance random effects model was used. RESULTS From 174 citations, 3 RCTs with 139 patients in each treatment group were included. Patients underwent a variety of GI surgeries. Patients treated with prucalopride had a decreased time to stool (mean difference 36.82 hours, 95% CI 59.4 to 14.24 hours lower, I2 = 62%, low certainty evidence). Other outcomes were not statistically significantly different (very low certainty evidence). Postoperative complications and adverse events could not be meta-analyzed due to heterogeneity; yet individual studies suggested no significant differences (very low certainty evidence). DISCUSSION Current RCT evidence suggests that prucalopride may enhance postoperative return of bowel function. Larger RCTs assessing patient important outcomes and associated costs are needed before routine use of this agent.

Abstract
Background In recent years, the attention paid to colorectal cancer (CRC) surgery and postoperative analgesia has increased. Objective The objective of the current study was to compare the impact of ultrasound-guided erector spinae plane block (ESPB) and transmuscular quadratus lumborum block (TQLB) upon providing relief to patients with postoperative pain who underwent laparoscopic resection for CRC. Methods In this prospective, comparative, and randomized study, the authors considered a total of 60 patients who chose to undergo laparoscopic resection for colorectal cancer. The total number of patients was randomly divided into two groups (such as ESPB and TQLB) so that each group had a total of 30 patients. For the former group, i.e., the ESPB group, 20 ml of 0.25% bupivacaine was administered at each side for bilateral ultrasound-guided erector spinae plane block, while the latter group received the same dose of medicine for bilateral ultrasound-guided transmuscular quadratus lumborum block (TQLB). The researchers recorded the first time to rescue an analgesic, the whole amount of rescue analgesia under consumption in the first 24 hours after the surgical procedure, and associated adverse events. Results Among the groups considered, the ESPB group took a significantly lengthy time to raise a first request for rescue analgesic (280 ± 15.5 min) in comparison with the TQLB group (260 ± 13.8 min). Likewise, the consumption of overall nalbuphine was remarkably lesser in the ESPB group during the first 24 hours (24 ± 2.5 mg) compared to the TQLB group (30.5 ± 1.55 mg). Conclusion The analgesic efficacy of ESPB was better when compared to TQLB in terms of time to rescue analgesia and overall opioid consumption during the first 24 hours. This study was registered at ClinicalTrials.gov on 10/10/2022 (registration number: NCT05574283).

Abstract
BACKGROUND Colorectal cancer is quite common, and surgery is the most effective treatment for most patients. However, postoperative pain management is generally inadequate in most patients. This study aimed to determine the effect of ultrasonography (USG)-guided preemptive erector spina plan block (ESPB), as part of multimodal analgesia, on postoperative analgesia in patients undergoing colorectal cancer surgery. METHODS: This is a prospective, randomized, single-blind trial. This study included 60 patients (ASA I-II) who underwent colorectal surgery at the hospital of Ondokuz Mayis University. The patients were divided into the ESP group and control group. Intraoperatively, all patients were administered intravenous tenoxicam (20 mg) and paracetamol (1 g) as part of multimodal analgesia. Intravenous morphine via patient-controlled analgesia was administered in all groups postoperatively. The primary outcome was the total morphine consumption in the first 24 h after surgery. The secondary outcomes included visual analog scale pain scores at rest and coughing and deep inspiration in the first 24 h and at 3 months postoperatively; number of patients requesting rescue analgesia; incidence of nausea and vomiting and need for antiemetics; intraoperative remifentanil consumption; postoperative first oral intake; time to first urination, first defecation, and first mobilization; hospitalization time; and incidence of pruritus. RESULTS Morphine consumption in the first 6 h postoperatively, total amount of morphine consumed in the first 24 h postoperatively, pain scores, intraoperative remifentanil consumption, incidence of pruritus, and postoperative antiemetic requirement were lower in the ESP group than in the control group. First defecation time and hospitalization time were shorter in the block group. CONCLUSIONS As a part of multimodal analgesia, ESPB reduced postoperative opioid consumption and pain scores in the early postoperative period and in the 3rd month.

The impact of low-pressure pneumoperitoneum on robotic-assisted radical cystectomy and intracorporeal ileal conduit urinary diversion: a case-control study. World J Urol 2022; 40:2467-2472. [PMID: 36065029 PMCID: PMC9512870 DOI: 10.1007/s00345-022-04117-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Accepted: 07/20/2022] [Indexed: 11/21/2022] Open
Abstract
Purpose To evaluate the role of low intra-abdominal pressure (IAP) in improving postoperative recovery in Robotic-assisted radical cystectomy (RARC) and intracorporeal ileal conduit urinary diversion (ICUD). Methods A retrospective case–control study of 49 bladder cancer patients offered RARC/ICUD with standard (12 mmHg, n = 24) or low IAP (8 mmHg, n = 25). Outcomes of interest included length of procedure (LoP), estimated blood loss (EBL), blood transfusion, margin positivity rates, time to first flatus (TtFF), time to first bowel movement (TtFBM), ileus and small bowel obstruction (SBO) rates, time to safe discharge (TtSD), postoperative hospital stay (PHS) and pain levels on a postoperative day (POD) 1 and 3. Perioperative complications were recorded using the Clavien-Dindo system. Results Demographic and baseline clinical characteristics, LoP, EBL and margin positivity rates were similar between groups. No transfusions were recorded. Median (IQR) TtFF, TtFBM and TtSD were significantly longer in Group 1 vs Group 2 (4 (1) vs 2 (1), 7 (3) vs 6 (2) and 8.5 (5.75) vs 5.0 (1), respectively). PHS and rates of postoperative ileus and SBO were lower in Group 2, however not statistically significant. Severe pain was uncommon in both groups but moderate/severe pain was significantly higher in Group 1 (95.8% vs 48% on POD1 and 62.5% vs 16% on POD3). No significant intraoperative complications were recorded and ≥ Grade 3 postoperative complications at 30 and 90 days were similar. Conclusion With limitations, Low-IAP RARC can be safely offered to RARC/ICUD patients and leads to faster bowel recovery, and shorter time to safe discharge compared to standard pneumoperitoneum.

Abstract
Most smokers are males, and smoking has been indicated as a risk factor for many cancers as well as postoperative complications after cancer surgery. However, little is known about whether smoking is a risk factor for postoperative ileus (POI) after radical rectal cancer resection in males. The aim of this study was to assess whether smoking is a risk factor for POI after radical resection in male rectal cancer patients.Data of 1486 patients who underwent radical resection for rectal cancer were extracted from the clinical medical system in our hospital and were statistically analyzed. POI was defined as nausea, vomiting or pain, failure to have bowel function for more than 4 days postoperatively, and absence of a mechanical bowel obstruction.The rate of POI was 12.79%. Univariate analysis showed that patients in the POI group were more likely to have a history of smoking and drinking and receive intraperitoneal chemotherapy and had a larger intraperitoneal chemotherapy dosage. In the multivariable analysis, smoking remained significantly associated with a higher incidence of POI (OR 2.238, 95% CI [1.545-3.240], P = .000). The results also showed that patients who received postoperative patient-controlled intravenous analgesia had a lower incidence of POI.Male patients with a history of smoking who undergo elective radical resection for rectal cancer have an increased risk for POI complications.

Abstract
Post-operative ileus (POI) is a syndrome of impaired gastrointestinal transit which occurs following abdominal surgery. There are few effective targeted therapies for ileus, and research has been limited by inconsistent definitions and an incomplete understanding of the underlying pathophysiology. Despite considerable effort, there remains no widely-adopted definition of ileus, and recent work has identified variation in outcome reporting is a major source of heterogeneity in clinical trials. Outcomes should be clearly-defined, clinically-relevant, and reflective of the underlying biology, impacts on hospital resources and quality of life. Further collaborative efforts will be needed to develop consensus definitions and a core outcome set for postoperative gastrointestinal recovery. Investigation into the pathophysiology of POI has been hindered by use of low-resolution techniques and difficulties linking cellular mechanisms to dysmotility patterns and clinical symptoms. Recent evidence has suggested the common assumption of post-operative GI paralysis is incorrect, and that the distal colon becomes hyperactive following surgery. The post-operative inflammatory response is important in the pathophysiology of ileus, but the time course of this in humans remains unclear, with the majority of evidence coming from animal models. Future work should investigate dysmotility patterns underlying ileus, and identify biomarkers which may be used to diagnose, monitor and stratify patients with ileus.

Abstract
INTRODUCTION Dexmedetomidine has opioid sparing actions but its effect on bowel recovery is controversial. Primary aim of this review was to evaluate the effect of perioperative dexmedetomidine on postoperative bowel recovery. Secondary aim was to evaluate the effect of dexmedetomidine on hospital discharge. EVIDENCE ACQUISITION Randomised controlled trials in English language reporting any or all of the following parameters of bowel recovery; time to first bowel sounds, first flatus, first faeces, or time to oral diet were included. EVIDENCE SYNTHESIS Twelve hundred and thirty-five patients from 13 studies were analysed. There were insufficient studies evaluating bowel sounds. Perioperative dexmedetomidine usage significantly reduced the time to first flatus [MD -5.61 hours (95% CI -8.61 to -2.60); P = 0.0003; I2 = 95%], first faeces [MD -12.70 hours (95% CI -19.11 to -6.29); P = 0.0001; I2 = 76%] and the composite outcome of bowel recovery (flatus, faeces, oral diet) [MD -7.44 hours (95% CI -10.31 to -4.57); P < 0.00001; I2 = 96%]. No difference was seen in the time to oral diet [MD -6.29 hours (95% CI -13.48 to 0.91); P = 0.09; I2 = 88%] or hospital discharge [MD -0.47 days (95% CI -1.27 to 0.33); P = 0.25; I2 = 86%]. CONCLUSIONS Perioperative dexmedetomidine usage significantly shortens the time to first flatus, faeces and composite bowel recovery but does not result in a shorter time to oral diet or earlier hospital discharge in adult patients receiving general anaesthesia. Strength of evidence is however very low for the effect of dexmedetomidine on bowel recovery.

Abstract
Background: Systemic inflammatory status is known as an important factor of colorectal cancer prognosis. Our study aimed to evaluate the performances of inflammation biomarker ratios as classification models of seven outcomes in patients with colorectal cancer. Methods: A retrospective cohort study was conducted on subjects with colorectal cancer over five years at a single center in Transylvania, Romania. Seven derived ratios were calculated based on laboratory data: neutrophil-to-lymphocyte (NLR), derived neutrophil-to-lymphocyte (dNLR), platelet-to-lymphocyte (PLR), lymphocyte-to-monocyte (LMR) and albumin-to-globulin (AGR) ratios, Systemic Immune Inflammation Index (SII) and Prognostic Nutritional Index (PNI). The utility of these ratios as predictors for seven outcomes was further evaluated in multivariable regression models. Results: Our study shows that the evaluated ratios exhibit specific performances for individual outcomes, proving a fair ability as screening tools (NLR and dNLR for survival, T stage and M stage; NLR and SII for T stage; and PLR for M stage). A dNLR over 3.1 (OR = 2.48, 95% CI (1.421 to 4.331)) shows predictive value for survival. A value of NLR over 3.10 (OR = 1.389, 95% CI (1.061 to 1.817)) is positively associated with an advanced T stage, while LMR is negatively related to the T stage (OR = 0.919, 95% CI (0.867 to 0.975)). NLR over 4.25 (OR = 2.647, 95% CI (2.128 to 3.360)) is positively associated with, while PNI is negatively related (OR = 0.970, 95% CI (0.947 to 0.993)) to, the M stage. Conclusion: Each of the evaluated ratios possesses prognostic value for certain outcomes considered, but the reported models need external validation to recommend their clinical practice utilization.

Abstract
OBJECTIVE Colorectal carcinoma (CRC) is the third most common cancer in the world and fifth most common cancer in India. To understand the extent of perineural invasion (PNI) in CRC it is essential to study the morphology of enteric glial cells (EGCs). The aim of the study was to analyze the numerical density of EGCs and area of myenteric ganglia (MG) in the colonic tissue samples collected from CRC patients. MATERIAL AND METHODS Fifteen intraoperative tissue specimens were collected from the tumor site and 2cm proximal to the upper extent of tumor. The samples were divided into four groups: group 1 (n=15): proximal tumor free colonic tissue; group 2 (n=3): well-differentiated; group 3 (n=8): moderately differentiated; group 4 (n=4): poorly differentiated adenocarcinoma. After processing the tissues were subjected to hematoxylin and eosin staining. The anti-S100β and anti-GFAP antibodies were used to observe the EGCs. RESULTS In the H&E stained sections the number of myenteric ganglia appeared to be decreasing with increasing grade of adenocarcinoma. Immunostaining showed significant decreasing pattern in the numerical density of EGCs per myenteric ganglion and mean area of myenteric ganglia in relation to the thickness of circular muscle, corresponding to the increasing grades of adenocarcinoma. The morphology of the EGCs remained unaltered in the colonic tissue adjacent to the tumor site. CONCLUSION Significant loss of EGCs and neurodegeneration corresponded with the grade of tumor emphasizing on its prognostic value. The PNI was not seen in the clear margin proximal to the tumor site.

Abstract
INTRODUCTION In order to compare the safety, efficacy, and oncological outcomes of laparoscopic (LC) and open colectomy (OC) for transverse colon cancer (TCC) patients, the present systematic review of the literature and meta-analysis was designed. METHODS This study was conducted following the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. A systematic screening of the electronic databases was performed (Medline, Web of Science and Scopus). The validity of the pooled results was verified through the performance of trial sequential analysis (TSA). The level of evidence was estimated using the GRADE approach. RESULTS Overall, 21 studies and 2498 patients were included in our study. Pooled comparisons and TSA analyses reported a superiority of LC over OC in terms of postoperative complications (OR 0.64, p = 0.0003), blood loss (WMD - 86.84, p < 0.00001), time to first flatus (WMD - 0.94, p < 0.00001) and oral diet (WMD - 1.25, p < 0.00001), and LOS (WMD - 2.39, p < 0.00001). Moreover, OC displayed a lower operation duration (p < 0.00001). A higher rate of complete mesocolic excision (p = 0.001) was related to OC. Although inconclusive in TSA, the recurrence rate in LC group was lower. LC and OC were equivalent in terms of postoperative survival outcomes. CONCLUSIONS Considering several limitations of the eligible studies and the subsequent low level of evidence, further RCTs of a higher quality and methodological level are required to verify the findings of our meta-analysis.

[PMID: 31686920 PMCID: PMC6751764 DOI: 10.2147/ijwh.s222922] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2019] [Accepted: 09/02/2019] [Indexed: 01/15/2023] Open
Abstract
Objective To compare the return of bowel movements in regionally anesthetized women undergoing cesarean section (C-section) given Early Oral Feeding (EOF) to that of women given Late Oral Feeding (LOF). Secondary outcomes of maternal satisfaction and gastrointestinal complications were also examined. Methods In a single-blinded randomized controlled trial (TCTR20181202001), 148 singleton pregnant women undergoing elective C-sections with regional anesthesia were assigned to receive either EOF or LOF. Participants began to sip water at 6–8 hrs or more than 12 hrs post-operation, for EOF or LOF respectively. Participants were then placed onto a stepping diet as tolerated. Participants failing to tolerate the stepping diet or those having surgical complications were excluded from the study. Results After exclusion, 69 women remained in the EOF group and 67 in the LOF group. The ages of participants ranged from 19 to 42, with a mean of 32.07. There was no-loss follow up and no significant difference in patient characteristics, except the site of the surgical incision. Participants given EOF were more likely to experience bowel sound the next morning than patients given LOF (EOF 87.0%, LOF 44.8%, P-value<0.001). However, there was no difference in time to passing flatus and time to passing stool. Maternal satisfaction regarding hunger (EOF 3.78±0.91, LOF 3.24±1.01, P-value 0.002) and maternal satisfaction with postoperative consumption (EOF 4.38±0.64, LOF 4.13±0.48, P-value 0.049) were significantly higher in the EOF group. There was no difference in gastrointestinal complications between the groups (P-value 0.978). Conclusion The EOF group experienced an earlier return of bowel movement and greater maternal satisfaction than the LOF group, with no difference in gastrointestinal complications. These findings support the recommendation of EOF for women who undergo uncomplicated C-sections under regional anesthesia.

Abstract
BACKGROUND Surgical resection with curative intent remains the standard of care for colon cancer. This study aims to compare the 30-day outcomes and oncologic results following open, laparoscopic, and robot-assisted right colon resection for colon cancer using the Targeted Colectomy American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. MATERIALS AND METHODS All patients undergoing elective, right colon resection with primary anastomosis were identified within the targeted colectomy ACS-NSQIP database. Only patients with stage I, II, or III colon cancer were included. The association of surgical approach with oncologic results and 30-day morbidity and mortality outcomes was investigated using a variety of statistical tests. RESULTS A total of 3518 patients met inclusion criteria; 1024 (29.1%) underwent open surgery (OS), 2405 (63.4%) underwent laparoscopic surgery, and 89 (2.5%) underwent robotic surgery. Patients undergoing OS were significantly more likely to have positive resection margins (P < .001). Patients undergoing OS were significantly more likely to experience prolonged intubation (P = .02), deep wound infections (P = .001), wound dehiscence (P = .005), deep venous thrombosis (P = .04), bleeding requiring a blood transfusion (P < .001), a prolonged postoperative ileus (P < .001), and longer length of hospital stay (P < .001), and were more likely to die (P = .02). CONCLUSION The laparoscopic approach to colon resection for colon cancer has lower 30-day morbidity compared to OS. The robotic approach is equivalent to the laparoscopic approach, and its utilization may increase in the future.

Abstract
BACKGROUND Chewing gum may enhance intestinal motility after surgery. This trial studied whether chewing gum could lead to a further reduction in ileus in patients who had a laparoscopic colorectal resection and followed an enhanced recovery programme. METHODS Patients undergoing laparoscopic colorectal resection were randomized to a control or intervention group. Patients in the control group received a standardized recovery programme. Patients in the intervention group were, in addition, given chewing gum three times daily from day 1 until discharge. Primary outcome measures were time to first flatus and first bowel motion. Time to feeling hungry and hospital stay were secondary outcome measures. RESULTS Forty-one patients were randomized into each group. Thirty-seven patients underwent rectal resection and 45 had a colonic resection. Time to passage of flatus was shorter (18 versus 34 h; P = 0·007), first bowel motion occurred earlier (19 versus 44 h; P = 0·001) and time to feeling hungry was earlier (16 versus 25 h; P = 0·001) in the intervention group. There was no difference in the duration of hospital stay (5 days in the intervention group versus 5·5 days in the control group). Subgroup analyses revealed that the benefits of chewing gum were clearer in patients who had a colonic resection, with a shorter time to first flatus (20 versus 35 h; P = 0·043), first bowel motion (19 versus 53 h; P = 0·014) and feeling hungry (14 versus 40 h; P = 0·001). No adverse events were attributed to chewing gum. CONCLUSION Chewing gum is a simple intervention that speeds intestinal transit in patients managed with a recovery programme after laparoscopic colorectal resection.

Abstract
BACKGROUND Enhanced recovery pathways (ERPs) are thought to improve surgical outcomes by standardizing perioperative patient care established in evidence-based literature. The objective of this study was to determine the impact of a colorectal surgery ERP on hospital length of stay (LOS) and other patient outcomes. METHODS This is a comparative effectiveness study of patients undergoing elective colorectal surgery 2 years prior (pre-ERP group) and 2 years after (ERP group) implementation of an ERP program. The primary outcome was hospital LOS. Secondary outcomes included postoperative complications, 30-day readmissions, and 30-day reoperations. Multivariable regression analyses were utilized to control for patient factors, general health factors, diagnosis, surgeon, colon versus rectal operations, and open versus minimally invasive operations-laparoscopic and robotic. An ERP checklist was developed to track adherence to components of the pathway. RESULTS The study population included 1036 patients: 523 in the pre-ERP group and 513 in the ERP group. Unadjusted LOS was significantly shorter in the ERP group than the control pre-ERP group [3 (IQR 3.5) vs 5 days (IQR 4.6); p < 0.0001]. Multivariable regression analysis confirmed the reduction in LOS, controlling for age, colon/rectum procedure, open/laparoscopic/robotic approach, primary diagnosis, and alvimopan use. Postoperative outcomes were not significantly different between groups except for 30-day readmissions, which were unexpectedly higher in the ERP group (14.6 vs 8.7 %, p = 0.04). CONCLUSIONS A newly implemented ERP on a dedicated colorectal surgery service in an academic non-university hospital setting resulted in shorter hospital LOS, but increased readmissions, for patients undergoing elective open and minimally invasive colon and rectal surgery. Future multi-institutional studies are needed to understand the impact of ERP on postoperative complications and readmissions.

Abstract
BACKGROUND Although patterns of return of bowel function (ROBF) following colorectal surgery with enhanced recovery after surgery (ERAS) programmes have been well delineated, regular morphine use is uncommon. This study describes the patterns of post-operative nausea and vomiting (PONV) and ROBF in this context. METHOD Patients undergoing elective major colorectal surgery on an ERAS programme over 1 year were included. Patient details, intra-operative course, post-operative management, outcomes and complications were collected retrospectively from clinical records. Statistical analysis was performed using Stata version 12. RESULTS A total of 136/142 (96%) patients received morphine for post-operative analgesia. Most (112/142, 79%) experienced either no vomiting (87/142, 61%) or small amounts (25/142, 18%). On average, patients without an ileostomy passed flatus and opened their bowels after 2.4 and 4.3 days, those with an ileostomy taking 1.5 and 2.1 days. Vomiting was not related to ROBF (P = 0.370) or overall complications; wound complications (odds ratio (OR) = 8.1, 95% confidence interval (CI): 2.0-32.5), electrolyte abnormalities (OR = 2.9, 95% CI: 1.2-7.1) and length of stay (hazard ratio = 1.3, 95% CI: 1.2-1.5) were related. CONCLUSION Most patients do not experience PONV in this context. ROBF is predictable without prolonged delays. This information could be used to allow confident early discharge and identify patients whose deviation from normal may indicate complications.

Abstract
BACKGROUND Postoperative ileus (POI) remains a major impediment in patient recovery and leads to longer lengths of stay at the hospital, readmission rates, and hospital costs. Alvimopan, a mu-opioid receptor antagonist, lowers POI incidence following open gastrointestinal surgery, however, little is known about its role on POI prevention among patients undergoing laparoscopic gastrointestinal surgery. METHODS A comprehensive search of PubMed/MEDLINE, Scopus, CINAHL, and Cochrane databases was performed (December 2014). Meta-analysis was performed using the Mantel-Haenszel (fixed effects) model with odds ratio (OR) to assess prevention of POI and hospital readmission. RESULTS Five studies were included in the final analysis. Pooling 4 of 5 studies, there was over a 75% relative risk reduction in POI development when patients were given alvimopan compared to placebo (OR 0.24, 95%CI 0.12-0.51, P=0.02). The number needed to treat with alvimopan to prevent one POI episode was 11 patients. There was a modest reduction in the length of hospitalization between 0.2 and 1.6 days. There did not appear to be a difference in frequency of 30-day readmission rate among the alvimopan group compared to placebo (OR 1.15, 95%CI 0.54-2.45, P=0.62). CONCLUSION Overall, there was a 75% relative risk reduction in POI development among patients undergoing laparoscopic gastrointestinal surgery. However, there did not appear to be a significant reduction in all-cause 30-day readmission rate or length of hospitalization. Future studies will need to address which subset of patients undergoing laparoscopic gastrointestinal surgery will benefit most from alvimopan.

Abstract
BACKGROUND Alvimopan (Entereg), a peripherally acting mu-opioid receptor antagonist, has been shown to expedite recovery of bowel function after colon resection surgery. Most data are available from industry-sponsored trials. This study aims to evaluate the clinical impact of this drug on perioperative outcomes and costs in patients undergoing segmental colonic resection for diverticular disease. METHODS A large administrative database maintained by the University Health System Consortium, an alliance of over 200 academic and affiliate hospitals, was queried from 2008 to 2011. International Classification of Diseases, 9th Revision, Clinical Modification codes for segmental colon resection because of diverticular disease were used to identify 2 matched cohorts of adult patients. University Health System Consortium's clinical resource manager was used to access pharmacy data and compare it with patient outcomes. RESULTS Five thousand two hundred ninety-nine patients met the above criteria. Four hundred thirty-eight patients received alvimopan and 4,861 did not. Regardless of laparoscopic or open approach, alvimopan significantly improved the postoperative length of stay (4.43 ± 2.02 vs 5.92 ± 3.79, P < .0001), cost (9,974 ± 4,077 vs 11,303 ± 6,968, P < .0001), and intensive care unit admission rate (1.83% vs 7.20%, P < .05), with no significant difference in mortality (.0% vs .19%, P = 1.000), morbidity (5.93% vs 8.39%, P = .08), or 30-day readmission rate (4.40% vs 4.63%, P = .90). CONCLUSIONS Alvimopan significantly reduced length of stay, days in the intensive care unit, and hospital cost for patients undergoing colonic segmental resections. Unlike some previously reported studies, we also observed a significant reduction in the length of stay in patients undergoing laparoscopic colectomies who received the drug. Alvimopan may reduce total healthcare costs if used as part of a best care practice model for colon resections.
