Abstract Background The cause of prolonged postoperative ileus (PPOI) is multifactorial. The influence of preoperative factors on PPOI has been well documented, but little is known about the impact of intraoperative conditions. The aim of this study was to investigate the influence of intraoperative factors on PPOI in patients undergoing colorectal surgery. Methods The LekCheck study database of the Colorectal Unit at the Royal Adelaide Hospital was analysed. Per patient, over 60 data points were prospectively collected between March 2018 and July 2020. Intraoperative data were collected in theatre during a one‐off snapshot measure. Univariate and multivariable logistic regression analyses were performed. Results Data of 336 patients were included. The median age was 66?years and 58.3% were male. Ninety‐three patients (27.7%) developed PPOI. Univariate analysis identified the following intraoperative variables as risk‐factors of PPOI: greater volumes of intraoperative IV fluid administration (464 versus 415?mL/h for those without PPOI; p?=?0.04), side‐to‐side anastomosis orientation (53.8 versus 41.2%; p?=?0.04) and increased perioperative opioid use (6.73 versus 4.11?mg/kg morphine equivalents for patients with and without PPOI, respectively; p?=?0.02). Upon multivariable analysis, increased perioperative opioid use remained significant (p?=?0.05), as well as the preoperative factors anticoagulation use (p?=?0.04) and higher levels of serum total protein (p?=?0.02). Conclusion This study suggests that intraoperative factors may also contribute to the development of PPOI, but this could not be confirmed in the multivariate analysis. Further studies including larger patient numbers will be required to determine the impact of intraoperative conditions on the development of PPOI.

Purpose Postoperative ileus (POI) is the paralytic disruption of gastrointestinal motility, a common complication following abdominal wall reconstruction that often leads to increased patient morbidity and length of stay (LOS). We reviewed two randomized clinical trials to determine POI rates, predictive factors, LOS, and associated cost. Methods Two randomized trials were performed from 2017-2019 with all patients receiving elective open abdominal wall reconstruction with retromuscular mesh. Using multivariate logistic regression, we performed a retrospective analysis including demographics and operative details from patients at a single site to determine predictive factors for POI. All medical costs encompassing surgery and the 30-day postoperative period were compared between ileus and non-ileus groups. Results Four hundred and seventy patients were reviewed with a POI rate of 13.0% (N = 61). There were no differences in age, body mass index (BMI), history of abdominal surgery, or comorbidities between patients with and without POI. Logistic regression showed no association with POI and age, BMI, hernia width, or operative time lasting longer than 4 h. Median LOS was 8 days for patients with POI compared to five for those without (p < 0.001). Relative median 30-day costs were 1.19 in patients with ileus and 1.0 in those without (p < 0.001). Conclusion We identified a 13% rate of POI in patients undergoing open abdominal wall reconstruction with mesh with no clearly identified predisposing factors. This resulted in a 3 days increase in median LOS and 19% additional costs. Further efforts should be devoted to investigating interventions that may reduce postoperative ileus after abdominal wall reconstruction.

Purpose: Prolonged Postoperative Ileus (PPOI) after abdominal surgery may affectunfavourably the patient recovery. The aim of this study was to estimate the incidence of PPOI in patientselective for colorectal resection and investigate perioperative variables associated with PPOI.Methods: A consecutive series of 428 patients undergoing colorectal resection (median age 72, range24-92, years; men/women ratio 1.14) were analyzed. Data were extracted retrospectively throughout afive-year period from an electronic prospectively maintained database. PPOI was defined as the needfor postoperative insertion of a nasogastric tube in a patient experiencing nausea and two episodes ofvomiting and further showing absence of adequate bowel function (absence of flatus/stool) with lackof bowel sounds and abdominal distension.Results: Incidence of PPOI was 7% [95% confidence interval (95%CI), 4.8-9.9%]. Mean hospital staywas 8 days longer in patients with PPOI. Male gender, cancer, cardiac and respiratory co-morbidity,rectal resection, open/converted access, duration of operation, stoma formation and body mass indexwere associated with PPOI at univariate analysis (0.001< P< 0.048). PPOI was independently associatedwith male gender [adjusted odds ratio (OR), 4.2; 95%CI, 1.5-11.5], stoma formation (OR, 2.8;95%CI, 1.2-6.8) and obesity (OR of obese vs. normal weight patients, 3.8, 95%CI, 1.2-12.0).Conclusion: After colorectal resection, PPOI leads to a prolonged hospital stay and slower patient’srecovery. An international standardized definition of PPOI is strongly needed to make comparable resultsfrom researches and to reliably identify patients with increased risk, also to improve the therapeuticpreventive policies in these patients.

Prolonged postoperative ileus (PPOI) is a common complication after colorectal surgery that increases patient discomfort, hospital stay, and financial burden. However, predictive tools to assess the risk of PPOI in patients undergoing laparoscopic low anterior resection have not been developed. Thus, the purpose of this study was to develop a nomogram to predict PPOI after laparoscopic low anterior resection for rectal cancer.A total of 548 consecutive patients who underwent laparoscopic low anterior resection for mid-low rectal cancer at a single tertiary medical center were retrospectively enrolled between January 2019 and January 2023. Univariate and multivariate logistic regression analysis was performed to analyze potential predictors of PPOI. The nomogram was constructed using the filtered variables and internally verified by bootstrap resampling. Model performance was evaluated by receiver operating characteristic curve and calibration curve, and the clinical usefulness was evaluated by the decision curve.Among 548 consecutive patients, 72 patients (13.1%) presented with PPOI. Multivariate logistic analysis showed that advantage age, hypoalbuminemia, high surgical difficulty, and postoperative use of opioid analgesic were independent prognostic factors for PPOI. These variables were used to construct the nomogram model to predict PPOI. Internal validation, conducted through bootstrap resampling, confirmed the great discrimination of the nomogram with an area under the curve of 0.738 (95%CI 0.736–0.741).We created a novel nomogram for predicting PPOI after laparoscopic low anterior resection. This nomogram can assist surgeons in identifying patients at a heightened risk of PPOI.

The aim of the present study was to investigate whether the measurement of cytokines from abdominal exudate is valuable for the early diagnosis of prolonged postoperative ileus (PPOI) following colorectal surgery. In the present study, 100 consecutive patients who were scheduled to undergo elective resection for carcinoma of the sigmoid or rectum were investigated. Abdominal exudate was obtained via a drain tube following surgery for the detection of interleukin (IL)-1β, IL-6 and tumour necrosis factor (TNF)-α. The correlation among the cytokine levels on postoperative days 1, 3 and 5 and the development of PPOI was investigated. Eight patients developed PPOI which was diagnosed 10-15 days postoperatively. No significant differences were observed among the peritoneal cytokine levels on postoperative days 1 and 3 in the 8 patients who developed PPOI when compared with those of the 92 patients that did not develop PPOI. By contrast, cytokine levels on postoperative day 5 were significantly higher in patients who developed PPOI when compared with those of patients that did not develop PPOI. The cytokine levels significantly increased during the first 5 days postoperatively in patients who developed PPOI and significantly decreased in patients who did not develop PPOI. The results of the present study showed that the increase in peritoneal IL-1β, IL-6 and TNF-α levels may be an additional early diagnostic predictor of PPOI following colorectal surgery.

Background Postoperative ileus occurs in up to 30% of colorectal surgery patients and is associated with increased length of stay, costs, and morbidity. While Enhanced Recovery Protocols seek to accelerate postoperative recovery, data on modifiable preoperative factors associated with postoperative ileus in this setting are limited. We aimed to identify preoperative predictors of postoperative ileus following colorectal surgery in Enhanced Recovery Protocols, to determine new intervention targets. Methods We performed a retrospective single-center cohort study of patients >= 18 years old who underwent colorectal surgery via Enhanced Recovery Protocols (7/2015-7/2017). Postoperative ileus was defined as nasogastric tube insertion postoperatively or nil-per-os by postoperative day 4. Preoperative risk factors including comorbidities and medication use were identified using multivariable stepwise logistic regression. Results Of 530 patients, 14.9% developed postoperative ileus. On univariate analysis of perioperative and postoperative factors, postoperative ileus patients had increased psychiatric illness, antidepressant and antipsychotic use, American Society of Anesthesiologists classification, ileostomy creation, postoperative opioid use, complications, surgery duration, and length of stay (p < 0.05). Multivariable logistic regression model for preoperative factors identified psychiatric illness, preoperative antipsychotic use, and American Society of Anesthesiologists classification >= 3 as significant predictors of postoperative ileus (p < 0.05). Discussion Postoperative ileus remains a common complication following colorectal surgery under Enhanced Recovery Protocols. Patients with pre-existing psychiatric comorbidities and preoperative antipsychotic use may be a previously overlooked cohort at increased risk for postoperative ileus. Additional research and preoperative interventions within Enhanced Recovery Protocols to reduce postoperative ileus for this higher-risk population are needed.

Although the mortality associated with major hepatopancreaticobiliary surgery has continuously decreased during the last decades, the morbidity of these procedures remains high. Functional disturbances of normal gastrointestinal motility as well as inflammation and infections of surgically treated organs are frequent complications resulting in considerably prolonged lengths of stay in hospital and increased healthcare costs. This review article highlights the therapeutic approaches and recent developments in the treatment of delayed gastric emptying, prolonged postoperative ileus, postoperative cholangitis and pancreatitis after hepatopancreaticobiliary surgery. Current practice is discussed on the basis of recent results in basic and clinical research, review articles, meta-analyses and guidelines.
