Prolonged Postoperative Ileus Following Elective Colectomy: A 2014-2019 National Surgical Quality Improvement Program Analysis.

Background/Aim. Postoperative ileus is a frequent and frustrating occurence for both, patients and surgeons after abdominal surgery. Besides clinical importance of postoperative ileus, its economic aspect is also important. The aim of this prospective study was to analyze development of prolonged postoperative ileus after elective colorectal surgery for cancer and its impact on early postoperative outcome. Methods. This prospective study included all eligible patients, 18 years or older, scheduled for open colorectal resection for cancer from June, 2015 to February, 2016. Patients with metastatic disease, prior hemoirradiation or any resection other then curative were excluded. The study duration was up to 30 days postoperatively. Primary outcome measure was development of prolonged postoperative ileus according to strict definition. The impact of prolonged postoperative ileus on other outcome measures such as postoperative complications, surgical site infections, anastomotic leakage, reoperations, mortality and length of hospital stay were of great interest, too. Results. This prospective study included 103 patients, 64 (37.9%) men and 39 (62.1%) women, mean age 66 years. Prolonged postoperative ileus developed in 12 (11.3%) patients. One third of the patients had some type of surgical site infection, while 47.6% had complications. Ten (9.7%) patients required reoperation. Comparing the group of patients with prolonged postoperative ileus with those without, there were no statistically significant differences in rates of surgical site infection and anastomotic leakage. There was statistically significant difference in terms of complications (_2 = 34.966; p < 0.001), complications grade III (_2 = 23.43; p < 0.001) and reoperations (_2 = 15.724; p <0.001). Patients who developed prolonged postoperative ileus had statistically significant longer postoperative hospital stay (Z = 2.291, p = 0.022) and longer total length of hospital stay (Z = 2.377, p = 0.015). According to regression analyzes prolonged postoperative ileus represents a risk factor for reoperations [odds ratio (OR) = 12.286; p = 0.001]. Conclusion. Prolonged postoperative ileus, although not life-threatening complication effects recovery, increases length of hospital stay and contributes to poor surgical outcome.

Prolonged ileus is one of the most common postoperative complications after colorectal surgery. We sought to investigate the predictors of prolonged ileus following elective colon resections procedures. The national participant user files of NSQIP databases were utilized to examine the clinical outcomes of patients undergoing elective colon resection during 2012-2013. Multivariate regression analysis was performed to investigate predictors of prolonged ileus. Prolonged ileus was defined as no return of bowel function in 7 days. We sampled a total of 27,560 patients who underwent colon resections; of these, 3497 (12.7%) patients had prolonged ileus. Patients with ileocolonic anastomosis (ICA) had a significantly higher rate of prolonged ileus compared to patients with colorectal anastomosis (CRA) (15 vs. 11.5%, AOR 1.25, P < 0.01). Prolonged ileus was significantly associated with intra-abdominal infections (13 vs. 2.8%, AOR 2.56, P < 0.01) and anastomotic leakage (12 vs. 2.4%, AOR 2.50, P < 0.01). Factors such as preoperative sepsis (AOR 1.63, P < 0.01), disseminated cancer (AOR 1.24, P = 0.01), and chronic obstructive pulmonary disease (AOR 1.27, P = 0.02) were associated with an increased risk of prolonged ileus, whereas oral antibiotic bowel preparation (AOR 0.77, P < 0.01) and laparoscopic surgery (AOR 0.51, P < 0.01) are associated with decreased prolonged ileus risk. Prolonged ileus is a common condition following colon resection, with an incidence of 12.7%. Among colon surgeries, colectomy with ICA resulted in the highest rate of postoperative prolonged ileus. Prolonged ileus is positively associated with anastomotic leak and intra-abdominal infections; thus, a high index of suspicion must be had in all patients with prolonged postoperative ileus.

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.

BackgroundThere were differences in the recovery of bowel function and prolonged postoperative ileus (PPOI) between laparoscopic right colectomy (RC) and left colectomy (LC) under the guidance of enhanced recovery after surgery.MethodsWe selected 870 patients who underwent elective laparoscopic colectomy from June 2016 to December 2021, including 272 patients who had RC and 598 who had LC. According to 1:1 proportion for propensity score matching and correlation analysis, 247 patients who had RC and 247 who had LC were finally enrolled.ResultsThe incidence of PPOI in all patients was 13.1%. Age, sex, smoking habit, preoperative serum albumin level, operation type, and operation time were the important independent risk factors based on multivariate logistic regression and correlation analysis for PPOI (p<0.05). Age, sex, body mass index, preoperative serum albumin level, operation time, and degree of differentiation between the two groups were significantly different before case matching (p<0.05). There were no statistically significant differences in baseline characteristics and preoperative biochemical parameters between the two groups after case matching (p>0.05). The incidence of PPOI in patients who had RC was 21.9%, while that in patients who had LC was 13.0%. The first flatus, first semi-liquid, and length of stay in LC patients were lower than those in RC patients (p<0.05).ConclusionThe return of bowel function in LC was faster than that in RC, and the incidence of PPOI was relatively lower. Therefore, caution should be taken during the early feeding of patients who had laparoscopic RC.

Postoperative gut dysmotility is a physiologic and frequent temporary reaction after major abdominal surgery. If paralysis merges into a prolonged ileus state, it causes significant morbidity and subsequently worse outcome and discomfort for the patients. Pathophysiology of pathologic prolonged postoperative paralytic ileus remains multifactorial. We present a retrospective single-center analysis of patients, who underwent a primary open oncologic anterior rectal resection with primary anastomosis with or without defunctioning loop ileostomy during a 43-month period of observation. Primary endpoint was the rate of prolonged postoperative paralytic ileus, defined by the intravenous administration of neostigmine. Confounders for regression analysis were assessed by univariate analysis and correlations between confounders were examined. Odds ratio for prolonged postoperative paralytic ileus in patients with defunctioning loop ileostomy was estimated by a logistic regression model. Of 101 patients (62 male), 62 (61.39%) received defunctioning loop ileostomy. In univariate analysis, male gender and patients with ileostomy showed more frequently prolonged paralysis by tendency (both p = 0.07). Logistic regression analysis proves the influence of a defunctioning ileostomy on the development of prolonged postoperative paralytic ileus after oncologic rectal resection (p = 0.047). Odds ratio for prolonged postoperative paralytic ileus in patients with ileostomy was 4.96 [95% CI 1.02-24.03]. Although the construction of defunctioning loop ileostomies during rectal resection is a safe, uncomplicated surgical procedure, they can cause significant postoperative morbidity for the patients. High fluid and electrolyte loss are well-known complications, but herewith we raise the evidence for prolonged gut paralysis in patients with defunctioning loop ileostomy.

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.

Risk factors associated with prolonged postoperative ileus after elective colon resection.

31 Background: Inflammatory markers such as the C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have recently been proposed as prognostic markers for post-operative complications and poor prognosis in solid tumors especially in colon cancer. However, there are few related reports in gastric cancer patients. Therefore, the aim of this study is to assess how perioperative inflammatory markers influence the prolonged postoperative ileus (PPOI) following gastric cancer surgery. Methods: Between 2013 and 2016, 435 patients were diagnosed with gastric cancer and underwent surgery in Gangnam Severance hospital. Patients were divided into prolonged postoperative ileus (PPOI) and control groups. Uncomplicated postoperative ileus (POI) is generally identified as an inevitable process after surgery, which typically resolves within 3 days. Ileus that persists for more than 3 days following surgery is termed PPOI. Results: The total PPOI rate was 33.8%. In univariate analysis, PPOI group was significantly associated with male sex, old age, open operative technique, preoperative gastric outlet obstruction and combined colon resection. PPOI group also was significantly associated with elevated perioperative inflammatory marker (pre- and post-operative CRP, NLR, and PLR). In multivariate analysis, open operative technique and elevated perioperative inflammatory markers (CRP, NLR and PLR) were identified as significant predictors of PPOI. In addition, postoperative length of hospital stay delayed in PPOI group compared with the control group (11.58 ± 9.48 vs.7.98 ± 5.44, respectively; P &lt; 0.001). Conclusions: In this study, PPOI group was significantly associated with elevated perioperative inflammatory marker. Patients with PPOI also are more likely to have an increased postoperative hospital stay. Therefore, the perioperative inflammatory markers may be used as clinically relevant predictive markers for PPOI following gastric cancer surgery

Risk factors associated with prolonged postoperative ileus after elective colon resection

BackgroundProlonged postoperative ileus (PPOI) is a common complication after abdominal surgery, but data about risk factors of PPOI for patients with gastric cancer are rare. We sought to investigate the impact of laparoscopic versus open surgery for PPOI after gastric cancer surgery.MethodsA retrospective cohort study was conducted using a registry database consecutively collected from June 2016 to March 2017. PPOI was defined as no bowel function persisting for more than 4 days. Univariate analysis and multiple logistic regression models were performed to investigate risk factors, and stratified analysis was carried out to examine the primary association at different levels of a potential confounding factor.ResultsA total of 162 patients composed of 63 patients undergoing laparotomy and 99 patients undergoing laparoscopy were enrolled and PPOI was observed in 32 (19.75%) patients. Risk factors significantly correlated with PPOI were as follows: open surgery, older age, late surgical pathologic staging, postoperative use of opioid analgesic, low level of postoperative albumin and serum potassium. Compared to open surgery, the laparoscopic surgery was a strong protective factor for PPOI after adjusting related variables (OR = 0.17, CI: 0.05‐0.52, P = .002). There was an interaction between surgical methods and the postoperative WBC level (P for interaction = .007). In the two group stratified analysis of WBC, laparoscopic surgery had a significant lower risk of PPOI than open group for the patients with WBC counts above the middle level in crude or adjusted models. This result remained significantly in the three group stratified analysis for the patients with WBC counts in the middle and or high tertile groups.ConclusionsPPOI is a common postoperative complication of patients after gastrectomy. Laparoscopic surgery is associated with decreased risk of PPOI in gastric surgery. Patients who underwent open surgery and presented with high level of WBC should be cautious with PPOI.

Prolonged postoperative ileus(PPOI), as a common surgical complication, has attracted more and more attention of domestic scholars in recent years. PPOI is often manifested as intolerance of oral feeding, nausea and vomiting, abdominal pain, abdominal distention, delayed exhaust and defecation, and prolonged hospital stay and increased medical expenditure. At present, the pathogenesis of PPOI has not been determined, but it is certain that the disease is mediated by a variety of mechanisms. In clinical work, PPOI still have no general diagnostic criteria, treatment methods and prevention strategies. The theory and practice of accelerated rehabilitation surgery may bring new ideas for the prevention and treatment of PPOI. This paper reviews the research status and prevention strategies of PPOI.

Passage of flatus and stool represents a key milestone in recovery after colonic resections. Colorectal surgeons may hold varied expectations regarding recovery rates after left- versus right-sided colectomies, but there is currently little evidence to inform post-operative care. This study prospectively compared gut function recovery after left- versus right-sided resections. Prospective data were analysed from 94 consecutive patients undergoing elective colorectal resections with primary anastomosis at Auckland City Hospital. Patients having ileostomies were excluded. Primary analysis compared time to first bowel motion between left- versus right-sided resections, excluding patients who developed prolonged post-operative ileus, while secondary analyses compared length of stay, rates of prolonged ileus and other complications. Analysis included 42 patients with left-sided and 52 with right-sided resections. No significant differences were observed for complications (P = 0.1), length of stay (P = 0.9) or development of prolonged ileus (P = 0.2). Rate of return of bowel function was faster in patients after left-sided resections (median 2.5 versus 4 days; P = 0.03 by Log-rank (Mantel-Cox) test), when patients with prolonged post-operative ileus were excluded. An association was also identified between length of bowel resected and time to recovery of bowel function for right-sided (P = 0.02) but not left-sided resections (P = 0.9). This study shows that for patients who do not progress to prolonged ileus, those with left-sided resections experience faster return of bowel function when compared with those having right-sided resections. The reason for this finding is currently unknown and deserves further attention.

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&lt;0.001). Significant earlier mobilization was observed in the laparoscopic group (3.12±1.77 vs. 5.39±3.48 days; P&lt;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.
