Incidence Of Prolonged Postoperative Ileus Research Articles

Effectiveness of acupuncture combined with auricular acupressure in the treatment of postoperative ileus: a study protocol for a randomized controlled trial.

About one-third of patients experience postoperative ileus (POI) after abdominal surgery, which can cause various complications and has not been treated well in clinical practice. The comprehensive treatment offered by traditional Chinese medicine may be a good choice for promoting intestinal mobility. Therefore, the aim of this study protocol is to observe the effectiveness of acupuncture combined with auricular acupressure in decreasing the incidence and related symptoms of POI. This is a single-center, assessor-blinded, randomized controlled trial. A total of 160 participants are supposed to recruit at Shanghai Tenth People's Hospital and randomly divided into two parallel groups in a 1:1 ratio. The intervention group are planned to receive manual acupuncture combined with auricular acupressure, while the control group are planned to receive regular enhanced recovery after surgery treatment. The primary outcome is the time to first defecation and first flatus after surgery. The secondary outcomes include the length of postoperative hospital stay, intensity of postoperative abdominal pain and distension, severity of postoperative nausea and vomiting, time to tolerate diet, inflammatory index, and incidence of prolonged postoperative ileus. The results of this research will provide substantial evidence regarding the efficacy of comprehensive traditional Chinese treatment, specifically auricular acupressure and manual acupuncture, in treating and preventing POI.

Prucalopride and Bowel Function Post Gastrointestinal Surgery: Systematic Review and Meta-Analysis of Randomized Controlled Trials.

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. 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. 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). 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.

Impact of STIMUlant and osmotic LAXatives (STIMULAX trial) on gastrointestinal recovery after colorectal surgery: randomized clinical trial.

Recovery of gastrointestinal (GI) function is often delayed after colorectal surgery. Enhanced recovery protocols (ERPs) recommend routine laxative use, but evidence of benefit is unclear. This study aimed to investigate whether the addition of multimodal laxatives to an ERP improves return of GI function in patients undergoing colorectal surgery. This was a single-centre, parallel, open-label RCT. All adult patients undergoing elective colorectal resection or having stoma formation or reversal at the Royal Adelaide Hospital between August 2018 and May 2020 were recruited into the study. The STIMULAX group received oral Coloxyl® with senna and macrogol, with a sodium phosphate enema in addition for right-sided operations. The control group received standard ERP postoperative care. The primary outcome was GI-2, a validated composite measure defined as the interval from surgery until first passage of stool and tolerance of solid intake for 24 h in the absence of vomiting. Secondary outcomes were the incidence of prolonged postoperative ileus (POI), duration of hospital stay, and postoperative complications. The analysis was performed on an intention-to-treat basis. Of a total of 170 participants, 85 were randomized to each group. Median GI-2 was 1 day shorter in the STIMULAX compared with the control group (median 2 (i.q.r. 1.5-4) versus 3 (2-5.5) days; 95 per cent c.i. -1 to 0 days; P = 0.029). The incidence of prolonged POI was lower in the STIMULAX group (22 versus 38 per cent; relative risk reduction 42 per cent; P = 0.030). There was no difference in duration of hospital day or 30-day postoperative complications (including anastomotic leak) between the STIMULAX and control groups. Routine postoperative use of multimodal laxatives after elective colorectal surgery results in earlier recovery of gastrointestinal function and reduces the incidence of prolonged POI.

Complications and postoperative ileus in laparoscopic versus open colectomy: A retrospective cohort study

Background: Postoperative complications are a major concern after colorectal surgery, and can lead to an increased burden on patients and the healthcare system. Complications include postoperative ileus (POI) and prolonged postoperative ileus (PPOI). There are well-established risk factors and potential modifiable risk factors that affect the incidence of POI and PPOI, including invasive techniques, operative difficulty, perioperative blood loss, and delayed mobilization. We compared the incidence of POI, PPOI, and other postoperative complications between laparoscopic colectomy and open colectomy. Methods: This retrospective review investigates 120 patients who underwent either laparoscopic or open colectomy in King AbdulAziz University Hospital in Jeddah, Saudi Arabia, between January 2016 and June 2019. Data were collected from patients’ electronic medical records. Patients were classified into laparoscopic and open colectomy groups. The main outcomes of interest were POI, PPOI and the overall complication rate. These outcomes were calculated and compared between the two groups. Results: The overall incidence of POI and PPOI was 4.2% and 15%, respectively. There was a higher incidence of POI in the laparoscopic approach group (7.2% vs. 1.5%, P=0.03); however, the incidence of PPOI was higher in the open approach group (20% vs. 9.1%, P=0.03). The open surgery group showed a higher rate of overall complications (P=0.001). The mean estimated blood loss was lower in the laparoscopy group (139.09±145.83 vs. 343.85±307.78 mL; P<0.001). Significant earlier mobilization was observed in the laparoscopic group (3.12±1.77 vs. 5.39±3.48 days; P<0.001). Conclusion: The incidence of PPOI was significantly different depending on the surgical approach; however, the laparoscopy group tolerated regular diet earlier and had better outcomes regarding postoperative complications. The laparoscopic approach was associated with earlier ambulation and was more cost-effective based on the length of the hospital stay. Further randomized studies are required to confirm superiority of the laparoscopic approach in terms of postoperative recovery.

Randomized Controlled Trial: Perioperative Dexamethasone Reduces Excessive Postoperative Inflammatory Response and Ileus After Surgery for Inflammatory Bowel Disease

An excessive postoperative inflammatory response is common after surgery for inflammatory bowel disease (IBD) and may be associated with an increased incidence of postoperative ileus. This study assessed the role of perioperative dexamethasone in postoperative ileus after IBD surgery. Patients undergoing elective IBD surgery were randomized to either an intravenous 8-mg dose of dexamethasone (n = 151) or placebo (n = 151) upon induction of anesthesia. The primary outcome was the incidence of prolonged postoperative ileus. Secondary outcomes included incidence of reported nausea or vomiting, time to first passage of flatus and stool, GI-2 recovery, postoperative pain, length of stay, and surgical complications. An intention-to-treat analysis revealed that patients who received dexamethasone exhibited a lower incidence of prolonged postoperative ileus (22.5% vs 38.4%; P = 0.003), shorter time to first passage of stool (28 vs 48 h, P < 0.001), GI-2 recovery (72 vs 120 h; P < 0.001), reduced postoperative length of stay (9.0 vs 10.0 d; P = 0.002), and less postoperative pain (P < 0.05) compared with controls. Moreover, there were no significant differences in postoperative nausea or vomiting (P = 0.531), major postoperative complications (P = 0.165), or surgical site infections (P = 0.337) between the groups. A benefit was only observed in patients with Crohn's disease, restored bowel continuity, colon/rectal resections, and those who underwent open operations. A single, intravenous 8-mg dose of dexamethasone upon induction of anesthesia reduced the incidence of prolonged postoperative ileus, the intensity of postoperative pain, and shortened the postoperative length of stay for IBD patients undergoing elective surgery.

Bowel function recovery after laparoscopic transverse colectomy within an ERAS program: a comparison to right and left colectomy

It is known that functional recovery of the bowel is slower after right colectomy (RC) compared to left colectomy (LC), but very little has been reported on transverse colectomy (TC). The aim of this study was to compare the clinical and early functional outcomes of TC, a more infrequent operation, to RC, and LC for colorectal cancer. Between December 2011 and December 2017, all patients undergoing elective colon resection in our institution were treated according to a standardized ERAS protocol and entered in a prospective database. We included in the study patients undergoing laparoscopic TC, RC, or LC for cancer with curative intent. The primary endpoint was prolonged postoperative ileus (PPOI), defined as need to insert a nasogastric tube, or refractory nausea VAS > 4 on or after the third postoperative day. Secondary endpoints were postoperative morbidity and length of hospital stay (LoS). Out of 286 patients, 126 met the inclusion criteria: 20 underwent TC, 65 RC, and 41 LC. Patients in LC group were younger than in TC and RC groups; other baseline demographics were similar. PPOI was observed in 5 (25%), 26 (40%), and 10 (24%) patients in TC, RC, and LC groups, respectively (p= 0.417). In single group comparisons, the incidence of PPOI in the TC group was significantly lower in comparison to the RC group (OR for RC: 4.255, 95% CI 1.092-16.667, p= 0.037) and similar to the LC group. No significant differences in terms of postoperative complications or LoS stay were observed. The incidence of PPOI after segmental laparoscopic colectomy for cancer within an ERAS program appears as infrequent in TC as in LC and lower than after RC. It may be reasonable to consider a slower oral intake after RC, as it represents an independent predictor of PPOI.

Mosapride Reduces Prolonged Postoperative Ileus after Open Colorectal Surgery in the Setting of Enhanced Recovery after Surgery (ERAS): A Matched Case-Control Study

Objective: To evaluate the effects of mosapride, a selective 5-hydroxytryptamine-4 agonist, on gastrointestinal recovery in patients undergoing open colorectal surgery. Methods: A prospectively collected database of the patients undergoing elective ‘open’ colorectal resection under enhanced recovery after surgery (ERAS) from May 2013 to April 2017 was reviewed. From April 2016, mosparide was routinely given from postoperative day 1 to discharge date. Eighty-four patients receiving mosapride were matched to 168 control patients (historical comparison with a ratio of 1:2). Surgical outcomes and postoperative gastrointestinal recovery was compared. Results: The patient characteristics were comparable except more patients in control group had perioperative administration of NSAIDs. The mosapride group had a 1.5% higher compliance rate of ERAS protocol. The control group had higher incidences of prolonged postoperative ileus (17.3% vs 7.1%; p=0.029) and prolonged postoperative ileus requiring nasogastric tube decompression (8.9% vs 3.6%; p=0.19). Overall complication, clinical intestinal transit and length of hospitalization were not significantly different between groups. However, the patients with prolonged postoperative ileus had significantly prolonged hospitalization (p<0.001). Median length of hospital stay was 4 days (IQR 4-5) in those without prolonged ileus (n=217), 5 days (IQR 5-6) in those with prolonged ileus without a need of gastric decompression (n=17) and 10.5 days (IQR 7-14.5) in those with prolonged ileus requiring nasogastric tube decompression (n=18) (p<0.001). A multivariate analysis showed that administration of mosapride was only a protective factor for prolonged postoperative ileus (OR=0.37, 95% CI=0.15-0.93, p=0.029). Conclusion: Postoperative administration of mosapride reduced the incidence of prolonged postoperative ileus after open colorectal surgery.

Incidence and predictors of prolonged postoperative ileus after colorectal surgery in the context of an enhanced recovery pathway.

Prolonged postoperative ileus (PPOI) is common after colorectal surgery but has not been widely studied in the context of enhanced recovery pathways (ERPs) that include interventions aimed to accelerate gastrointestinal recovery. The aim of this study is to estimate the incidence and predictors of PPOI in the context of an ERP for colorectal surgery. We analyzed data from an institutional colorectal surgery ERP registry. Incidence of PPOI was estimated according to a definition adapted from Vather (intolerance of solid food and absence of flatus or bowel movement for ≥ 4days) and compared to other definitions in the literature. Potential risk factors for PPOI were identified from previous studies, and their predictive ability was evaluated using Bayesian model averaging (BMA). Results are presented as posterior effect probability (PEP). Evidence of association was categorized as: no evidence (PEP < 50%), weak evidence (50-75%), positive evidence (75-95%), strong evidence (95-99%), and very strong evidence (> 99%). There were 323 patients analyzed (mean age 63.5years, 51% males, 74% laparoscopic, 33% rectal resection). The incidence of PPOI was 19% according to the primary definition, but varied between 11 and 59% when using other definitions. On BMA analysis, intraoperative blood loss (PEP 99%; very strong evidence), administration of any intravenous opioids in the first 48h (PEP 94%; strong evidence), postoperative epidural analgesia (PEP 56%; weak evidence), and non-compliance with intra-operative fluid management protocols (3ml/kg/h for laparoscopic and 5ml/kg/h for open; PEP 55%, weak evidence) were predictors of PPOI. The incidence of PPOI after colorectal surgery is high even within an established ERP and varied considerably by diagnostic criteria, highlighting the need for a consensus definition. The use of intravenous opioids is a modifiable strong predictor of PPOI within an ERP, while the role of epidural analgesia and intraoperative fluid management should be further evaluated.

Mosapride reduces the incidence of prolonged postoperative ileus after open colorectal surgery

Mosapride reduces the incidence of prolonged postoperative ileus after open colorectal surgery

Delayed postoperative diet is associated with a greater incidence of prolonged postoperative ileus and longer stay in hospital for patients undergoing gastrointestinal surgery.

Recent evidence favours a move away from delaying postoperative nutrition towards early feeding practices for better patient outcomes after gastrointestinal surgery. The aim of the present study was to investigate postoperative diet progression and patient outcomes in a secondary hospital with a view to inform future practice. This was a retrospective study of gastrointestinal surgery patients (n = 69) at a Western Australian general hospital. Demographic data and outcomes were collected from patient records and included presence or absence of prolonged postoperative ileus, length of stay in hospital, days on minimal nutrition and days until first flatus or stool. A significant positive association was observed between number of days a patient remained on minimal nutrition and length of stay in the overall group (r = 0.66, P < 0.01). Patients who developed prolonged postoperative ileus (n = 18, 26%) had a greater number of days on minimal nutrition (20.0 vs 8.0 days, P < 0.01), longer stay in hospital (15.0 vs 8.0 days, P < 0.01) and increased number of days to first flatus or stool (4.0 vs 2.4 days, P < 0.01) compared with those who did not develop prolonged postoperative ileus (n = 51, 74%). This retrospective study of current practice in a secondary-care general hospital highlights the gap between traditional care and the improved outcomes reported in the literature when early feeding practices are adopted after GI surgery. Further investigation of barriers and enablers is necessary to provide insight into developing the most appropriate strategy to achieve this.

The Incidence of Prolonged Postoperative Ileus After Laparoscopic Colorectal Surgery—Does ERAS Protocol Bring Anything New?

A substantial percentage of patients undergoing colorectal surgery develop prolonged postoperative ileus (PPOI). Since the data on its incidence and risk factors in patients undergoing laparoscopic colorectal surgery with ERAS protocol are sparse, we aimed to analyse them in a group of 295 consecutive patients operated on laparoscopically for colorectal cancer. The study was a prospective observation of 295 patients. In all of them, the 16-item ERAS protocol was applied. The primary outcome was the occurrence of PPOI. Secondary outcomes were risk factors of PPOI. PPOI incidence rate was 9.8%. In 8 (27.6% of PPOI group) patients, it was secondary to other underlying complication. In the remaining 21 (72.4% of PPOI group) cases, it was primary. In 80.9% cases, it resolved completely by five postoperative days. Using univariate regression analysis, we observed that only the female sex (OR 2.71) was an independent predictor of PPOI development, whereas age >65 years was associated with a lower risk (OR 0.33). Also patients after procedures involving handling the small bowel were more likely to develop PPOI (OR 2.65). The remaining demographic and perioperative parameters were not statistically significant. The incidence of PPOI in patients after laparoscopy with ERAS protocol is low and usually resolves within 5 days. However, longer PPOI may indicate underlying complications. Traditional risk factors for PPOI seem to play a limited role in its development.

Effectiveness of continuous wound infusion of local anesthetics after abdominal surgeries

BackgroundTo assess the effectiveness of continuous preperitoneal wound infusion of local anesthetic drug bupivacaine in providing pain relief, reducing opioid consumption, and enhancing postoperative recovery. MethodsEligible patients were randomly allocated to two groups (study group: bupivacaine and control group: normal saline). There were 47 patients in each group. The patients received continuous infusion of either 0.25% bupivacaine or 0.9% normal saline at 6 mL/h, for 48 h, based on their group allocation, through a multiholed wound infiltration catheter placed preperitoneally. All patients also received intravenous morphine through patient-controlled analgesia pump. Pain scores at rest and on cough, morphine consumption, and peak expiratory flow rate were assessed at 12, 24, and 48 h postoperatively. The time to first perception of bowel sounds and first passage of flatus was noted. All patients were assessed for postoperative nausea and vomiting and any local or systemic complications. Chi-square test was used to compare categorical variables. The morphine consumption was compared using Student t-test, the visual analogue scale (VAS) scores were compared using repeated-measures analysis of variance. ResultsThe mean total morphine consumption in the study group was significantly lower than the control group (18.8 ± 2.21 versus 30.8 ± 2.58 mg, P = 0.001). The median VAS scores were significantly lower in the study group than those in the control group both at rest (3 [1-4] versus 4 [2-5], P = 0.04) and during cough (4 [3-6] versus 6 [4-6] P = 0.03), except at 48 h, when the median VAS score at rest was similar (3 [1-4] versus 3 [2-4], P = 0.56). Bowel function returned earlier in study group (67.34 ± 2.61 versus 76.34 ± 5.29 h, P = 0.03). Postoperative nausea and vomiting was less in study group. Respiratory function, assessed by peak expiratory flow rate, was better in the study group (192.55 ± 12.93 versus 165.31 ± 9.32 mL, P = 0.03). The incidence of surgical site infection was similar in both the groups (3/47 versus 5/47, P = 0.06). There was no systemic toxicity of local anesthetic. ConclusionContinuous preperitoneal wound infusion of local anesthetic provides effective analgesia, reduces morphine consumption and its associated side effects, and enhances the postoperative recovery by reducing the incidence of prolonged postoperative ileus.

Incidence of prolonged postoperative ileus after colorectal surgery: a systematic review and meta-analysis.

Prolonged postoperative ileus (PPOI) after colorectal surgery remains a leading cause of delayed postoperative recovery and prolonged hospital stay. Its exact incidence is unknown. The aim of this systematic review is to investigate the definitions and incidence of PPOI previously described. MEDLINE, Embase and the Cochrane Database of Systematic Reviews (up to July 2014) were searched. Two authors independently reviewed citations using predefined inclusion and exclusion criteria. The search strategy yielded 3233 citations; 54 were eligible, comprising 18983 patients. Twenty-six studies were prospective [17 of these being randomized controlled trials (RCTs)] and 28 were retrospective. Meta-analysis revealed an incidence of PPOI of 10.3% (95% CI 8.4-12.5) and 10.2% (95% CI 5.6-17.8) for non-RCTs and RCTs, respectively. Significant heterogeneity was observed for both non-RCTs and for RCTs. The used definition of PPOI, the type of surgery and access (laparoscopic, open) and the duration of surgery lead to significant variability of reported PPOI incidence between studies. The incidence of PPOI is lower after laparoscopic colonic resection. There is a large variation in the reported incidence of PPOI. A uniform definition of PPOI is needed to allow meaningful inter-study comparisons and to evaluate strategies to prevent PPOI.

Economic Impact of Alvimopan Considering Varying Definitions of Postoperative Ileus

Prolonged postoperative ileus (POI) is the predominant cause of extended hospitalization after bowel resection surgery. Alvimopan accelerates gastrointestinal recovery, potentially reducing health care costs. We examined the value of alvimopan in reducing prolonged POI and length of stay for patients undergoing abdominal surgery using different definitions of POI. We developed a decision analytic model to examine costs and outcomes associated with postoperative treatment with either an accelerated care pathway (ACP) only or alvimopan+ACP. To represent an overall perspective for alvimopan, data from four phase 3 bowel resection trials and one phase 4 radical cystectomy trial were used to populate the model with 3 different definitions of POI. The period analyzed included start of surgery to 7 days post discharge. Costs were obtained from standard US costing sources and are reported in 2015 US dollars. Due to variations in published definitions of POI, alternative definitions based on adverse event reports, NG tube insertion, and time to food toleration were examined. The combined clinical trial data included 1,003 ACP and 1,013 alvimopan+ACP patients. When POI was reported as an adverse event, the incidence of POI was significantly lower with alvimopan+ACP (n= 70 [7%]) vs ACP alone (n= 148 [15%]; p < 0.0001). Time to discharge order written was shorter for patients with POI who were treated with alvimopan+ACP than with ACP (202 ± 115 hours vs 266 ± 138 hours; p < 0.0001). As a result, costs were $731 lower with alvimopan+ACP ($17,835) vs ACP ($18,566). Alternative definitions of POI produced similar results. The addition of alvimopan to existing treatment pathways for patients undergoing abdominal surgery can reduce overall hospital costs.

Enhanced recovery program in laparoscopic colectomy for cancer

IntroductionBoth laparoscopic colectomy and application of enhanced recovery program (ERP) in open colectomy have been demonstrated to enable early recovery and to shorten hospital stay. This study evaluated the impact of ERP on results of laparoscopic colectomy and comparison was made with the outcomes of patients prior to the application of ERP.MethodsAn ERP was implemented in the authors’ center in December 2006. Short-term outcomes of consecutive 84 patients who underwent laparoscopic colonic cancer resection 23 months before (control group) and 96 patients who were operated within 13 months; after application of ERP (ERP group) were compared.ResultsBetween the ERP and control groups, there was no statistical difference in patient characteristics, pathology, operating time, blood loss, conversion rate or complications. Compared to the control group, patients in the ERP group had earlier passage of flatus [2 (range: 1–5) versus 2 (range: 1–4) days after operation respectively; p = 0.03)] and a lower incidence of prolonged post-operative ileus (6% versus 0 respectively; p = 0.02). There was no difference in the hospital stay between the two groups [4 (range: 2–34) days in control group and 4 (range: 2–23) days in ERP group; p = 0.4)]. The re-admission rate was also similar (7% in control group and 5% in ERP group; p = 0.59).ConclusionsIn laparoscopic colectomy for cancer, application of ERP was associated with no increase in complication rate but significant improvement of gastrointestinal function. ERP further hastened patient recovery but resulted in no difference in hospital stay.

Postoperative intussusception in infants and children

Postoperative intussusception occurring in infants and small children presents few of the classic symptoms or signs of idiopathic intussusception. Rectal hemorrhage is rarely seen. Distention routinely makes palpation for an abdominal mass unrewarding. Contrast roentgenographic studies of the colon are of little diagnostic value. Upper intestinal contrast studies are singularly unsuccessful in identifying the specific nature of this form of intestinal obstruction. In general, intestinal intubation therapy is more confusing than helpful. Since the incidence of prolonged postoperative ileus in this age group is low, such a diagnosis should be regarded with skepticism in a patient with intestinal obstruction developing after abdominal surgery. Laparotomy should not be delayed unduly since the principal diagnostic possibilities (excluding anastomatic obstruction) are postoperative adhesions and postoperative intussusception.
