Background: Postoperative ileus (POI) is a common complication after colorectal surgery, leading to increased hospital stay and costs. This study aimed to explore patient comorbidities that contribute to the development of POI in the colorectal surgical population and compare machine learning (ML) model accuracy to existing risk instruments. Study Design: In a retrospective study, data were collected on 316 adult patients who underwent colorectal surgery from January 2020 to December 2021. The study excluded patients undergoing multi-visceral resections, re-operations, or combined primary and metastatic resections. Patients lacking follow-up within 90 days after surgery were also excluded. Eight different ML models were trained and cross-validated using 29 patient comorbidities and four comorbidity risk indices (ASA Status, NSQIP, CCI, and ECI). Results: The study found that 6.33% of patients experienced POI. Age, BMI, gender, kidney disease, anemia, arrhythmia, rheumatoid arthritis, and NSQIP score were identified as significant predictors of POI. The ML models with the greatest accuracy were AdaBoost tuned with grid search (94.2%) and XG Boost tuned with grid search (85.2%). Conclusions: This study suggests that ML models can predict the risk of POI with high accuracy and may offer a new frontier in early detection and intervention for postoperative outcome optimization. ML models can greatly improve the prediction and prevention of POI in colorectal surgery patients, which can lead to improved patient outcomes and reduced healthcare costs. Further research is required to validate and assess the replicability of these results.

Gallstone ileus is an uncommon occurrence and accounts for about 0.3-0.5% of complications of cholelithiasis in elderly patients. Bouveret syndrome is an uncommon medical condition resulting from the blockage of the duodenal bulb by a stone, which consequently obstructs the outlet of the stomach. Until now, a comparison of two different presentations of Bouveret syndrome has not been published in the literature due to the rarity of this pathology. The curious simultaneous occurrence of the two cases discussed here made it possible for us to compare the different diagnostic and therapeutic pathways. In fact, both cases differ not only in their presenting symptoms, but also in the management adopted by the same surgical team.

BACKGROUND: The benefit of chemoprophylaxis (CPX) agents in preventing venous thromboembolism must be weighed against potential risks. Current literature regarding the efficacy of CPX after laminectomies with or without fusion is limited, with no clear consensus to inform guidelines.
OBJECTIVE: This study evaluated the association between CPX and surgical complications after lumbar laminectomy with and without fusion.
METHODS: Retrospective study of patients at a single large academic institution.
METHODS: The medical records of patients who underwent lumbar laminectomies with or without lumbar fusion from 2018 to 2020 were reviewed for demographics, surgical characteristics, CPX agents, postoperative complications, epidural hematomas, and wound drainage. Patients receiving CPX (n = 316) were compared with patients not receiving CPX (n = 316) via t test following propensity score matching, and patients on CPX were further stratified by fusion status.
RESULTS: The CPX group had higher body mass index and American Society of Anesthesiologists grades. Rates of venous thromboembolism, epidural hematomas, infections, postoperative incision and drainage, transfusions, wound dehiscence, and reoperation were not associated with CPX. Moist dressings were more frequent, and average days of drain duration were longer with CPX. Overall postoperative complication rate and length of stay (LOS) were greater with CPX. The fusion subgroup had a lower Charlson Comorbidity Index, had a lower American Society of Anesthesiologists grade, was younger, had more women, and underwent more minimally invasive laminectomies. While estimated blood loss, operative times, and LOS were significantly greater in the fusion group, there was no difference in rate of intraoperative and postoperative complications.
CONCLUSIONS: CPX after lumbar laminectomies with or without fusion was not associated with increased rates of epidural hematomas, wound complications, or reoperation. Patients receiving CPX had more postoperative cardiac complications, but it is possible that surgeons were more likely to prescribe CPX for higher-risk patients. They also had higher rates of ileus and moist dressings, greater LOS, and longer length of drain duration. Patients who underwent lumbar laminectomy with fusion on CPX tended to be lower risk yet incurred greater blood loss, operative times, LOS, cardiac complications, and hematomas/seromas than patients not undergoing fusion.
CONCLUSIONS: This retrospective study compared surgical complications of lumbar laminectomies in patients who received chemoprophylaxis vs patients who did not. Chemoprophylaxis was not associated with increased rates of epidural hematomas, wound complications, or reoperation, but it was associated with higher rates of postoperative cardiac complications and ileus.

BACKGROUND: Ileus is a common complication of major abdominal surgery, including colorectal resection. The present study aimed to assess the predictors of ileus after laparoscopic right colectomy for colon cancer.
METHODS: This study was a retrospective case-control analysis of a prospective IRB-approved database of patients who underwent laparoscopic right colectomy at the Department of Colorectal Surgery, Cleveland Clinic Florida. Patients who developed ileus after right colectomy were compared to patients without ileus to determine the risk factors of ileus.
RESULTS: The present study included 270 patients with a mean age of 68.7 years. Thirty-six patients (13.3%) experienced ileus after laparoscopic right colectomy. The median duration of ileus was 6 days. Factors associated with ileus were age (71.6 vs 68.2 years, P = .158), emergency colectomy (11.1% vs 3.9%, P = .082), extended hemicolectomy (19.4% vs 6.8%, P = .021), green gastrointestinal anastomosis (GIA) 4.8mm staple height cartridge (19% vs 8.1%, P = .114), and longer operative time (177.9 vs 160.4 minutes, P = .157). The only independent predictor of ileus was extended colectomy (OR: 16.7, P = .003).
CONCLUSIONS: Increased age, emergency surgery, green GIA cartridge, and longer operative times were associated with ileus, yet the only independent predictor of ileus was extended right hemicolectomy.

OBJECTIVE: The recovery of gastrointestinal function and postoperative ileus are the leading goals for clinicians following surgery for adhesive small bowel obstruction. While enhanced recovery programs may improve recovery, their feasibility in emergency surgery has not yet been proven. We sought to assess the incidence of postoperative ileus in patients following surgery for ASBO and the feasibility of enhanced recovery programs, including their benefits in the recovery of gastrointestinal functions and reducing the length of hospitalization.
METHODS: This prospective study includes the first 50 patients surgically treated for ASBO between June 2021 and November 2022. Their surgery was performed either as an emergency procedure or after a short course of medical treatment. The main aim was to compare the observed rate of postoperative ileus with a theoretical rate, set at 40%. The study protocol was registered in clinicaltrials.gov under the number NCT04929275.
RESULTS: Among the 50 patients included in this study, it reported postoperative ileus in 16%, which is significantly lower than the hypothetical rate of 40% (p = 0.0004). The median compliance with enhanced recovery programs was 75% (95%CI: 70.1-79.9). The lowest item observed was the TAP block (26%) and the highest observed items were preoperative counselling and compliance with analgesic protocols (100%). The overall morbidity was 26.5%, but severe morbidity (Dindo-Clavien > 3) was observed in only 3 patients (6%). Severe morbidity was not related with the ERP.
CONCLUSIONS: Enhanced recovery programs are feasible and safe in adhesive small bowel obstruction surgery patients and could improve the recovery of gastrointestinal functions.
BACKGROUND: NCT04929275. WHAT DOES THE STUDY CONTRIBUTE TO THE FIELD?: Perioperative management of adhesive small bowel obstruction (ASBO) surgery needs to be improved in order to reduce morbidity. Enhanced recovery programs (ERP) are both feasible and safe following urgent surgery for ASBO. ERPs may improve the recovery of gastrointestinal (GI) functions.

Postoperative ileus (POI) is a prevalent surgical complication, which results in prolonged hospitalization, patient distress, and substantial economic burden. The literature aims to present a brief outline of interventions for preventing and treating POI post-surgery. Data from 2014 to 2023 were gathered from reputable sources like PubMed, PubMed Central, Google Scholar, Research Gate, and Science Direct. Inclusion criteria focused on studies exploring innovative treatments and prevention strategies for POI, using keywords such as novel POI treatments, non-pharmacological prevention, POI incidence rates, POI management, and risk factors. The findings revealed that integration of preventive measures such as coffee consumption, chewing gum, probiotics, and use of dikenchuto within enhanced recovery programs has significantly reduced both the frequency and duration of POI, without any adverse effects, with minimally invasive surgical approaches showing promise as an additional preventive strategy. While treatment options such as alvimopan, NSAIDs, and acupuncture have demonstrated efficacy, the use of lidocaine has raised concerns due to associated adverse effects. The ongoing exploration of novel therapeutic strategies such as targeting the mast cells, vagal nerve stimulation and tight junction protein, and prokinetic-mediated instigation of the cholinergic anti-inflammatory trail not only holds promise for enhanced treatment but also deepens the understanding of intricate cellular and molecular pathways underlying POI. POI presents a complex challenge in various surgical specialties, necessitating a multifaceted management approach. The integration of preventive and treatment measures within enhanced recovery programs has significantly reduced POI frequency and duration.

Ingestion of foreign bodies is a rare clinical problem in healthy adults. Less than 1% of cases need surgery due to perforation or obstruction. Here, we describe an unusual case of a wine-cork ingestion by a 54-year-old woman with a history of chronic alcohol consumption. Computed tomography (CT) of the abdomen and pelvis revealed foreign body (FB) in terminal ileum. The proximal part of the ileum was dilated due to obstruction. Laparotomy was performed, and the FB was removed without complications. Most ingested FBs spontaneously pass through the gastrointestinal tract. However, in rare instances, the FB can cause obstruction. In case of suspicion of serious complications such as obstruction and perforation, abdominopelvic CT should be used. The application of radiographic techniques in the identification of FBs and the assessment of potential complications plays a crucial role in expediting medical interventions for patients.

BACKGROUND: Numerous measurement techniques for intra-abdominal pressure have been explored, with the Kron Technique established as the gold standard. Despite its prominence, the search for alternative methods persists due to its lengthy application time, the requirement for additional equipment, and overall impracticality. This study investigated a quicker, more accessible method for effective intra-abdominal pressure measurement in the emergency department. It aimed to compare intra-abdominal pressure measurements in patients diagnosed with ileus using a digital manometer and the Kron Technique.
METHODS: Conducted from October 2022 to February 2023, this single-center, prospective, single-blind method comparison study involved patients diagnosed with ileus at a tertiary emergency department. Intra-abdominal pressure was measured using both the Kron Technique and a digital manometer by separate practitioners blinded to the study results.
RESULTS: The study included 30 patients. No statistically significant difference was observed in the intra-abdominal pressure measurements between the two methods (p<0.237). A very strong correlation existed between the two methods (Spearman\'s Rho = 0.998). Bland-Altman analysis showed a bias value of 0.091 mmHg for the digital manometer, with upper and lower agreement limits of -0.825 and 1.007 mmHg, respectively. The measurement time was significantly shorter with the digital manometer than with the Kron Technique (15 vs. 390.5 seconds; p<0.001).
CONCLUSIONS: We believe that the intra-abdominal pressure measurement technique using a digital manometer is a method that can be effectively employed by healthcare professionals in emergency departments. This technique offers ease of use, requires minimal equipment, provides rapid results, and delivers reliable measurement values compared to the Kron Technique.

The primary objective of this study was to compare short-term outcomes between Intracorporeal ileocolic anastomosis (IIA) and extracorporeal ileocolic anastomosis (EIA) after laparoscopic right hemicolectomy in patients with visceral obesity. The secondary objective was to identify risk factors associated with prolonged postoperative ileus (PPOI) after laparoscopic right hemicolectomy. This single-center retrospective study analyzed visceral obesity patients who underwent laparoscopic right hemicolectomy for primary bowel cancer between January 2020 and June 2023. Patients were categorized into IIA and EIA groups based on the type of anastomosis, and a 1:1 propensity score-matched analysis was performed. A total of 129 patients were initially included in this study, with 45 patients in each group following propensity score matching. The IIA group had significantly longer anastomosis times (p < 0.001), shorter incision length (p < 0.001), and shorter length of stay (p = 0.003) than the EIA group. Meanwhile, the IIA group showed a shorter time to first flatus (p = 0.044) and quicker tolerance of a solid diet (p = 0.030). On multivariate analysis, postoperative use of opioid analgesics is an independent risk factor for PPOI (OR: 3.590 95% CI 1.033-12.477, p = 0.044), while IIA is an independent protective factor (OR: 0.195 95% CI 0.045-0.843, p = 0.029). IIA remains a safe and feasible option for visceral obesity patients. It is also associated with a quicker recovery of bowel function and shorter length of stay when compared to EIA. Additionally, IIA is an independent protective factor for PPOI.
