Relevance of Medical Imaging in the Pre-Therapeutic Evaluation of Acute Intestinal Obstruction at CIMED

Objective: We initiated this work with the aim of studying the contribution of imaging in the diagnosis of acute intestinal obstruction at CIMED. Patients and methods: This was a prospective, descriptive and analytical study involving 96 patients collected at the radiology and medical imaging department of CIMED, from January 2022 to January 2023. Result: The age of our patients varied between 11 and 86 years with an average age of 36 years. There was a male predominance of 64.6% compared to 35.4% for women, i.e. a sex ratio of 1.82. The notion of previous surgery was found in 61.5% of our patients. Pain was present in all patients. Radiography of the ASP was performed in 89.6% of patients. It showed hydro-aerial levels in 96.5% of patients. Abdominopelvic CT was performed in 12 patients and made it possible to make the diagnosis of occlusion in all patients. The results of the positive diagnosis were concordant with those intraoperatively in 92% of cases. 8% of our patients, compared to the treatment, spontaneously resumed their transit, 91% benefited from surgical treatment and 1% died before surgery. The outcome was favorable in 80 patients or 83.3%, poor with death in 16 patients or 16.7% of cases. Conclusion: Acute intestinal obstruction remains a serious pathology for which ASP radiography often remains the only radiological examination performed urgently. However, abdominopelvic CT seems widely indicated thanks to its contribution both for the positive diagnosis and for the serious and etiological diagnoses. However, this imaging technique is largely underused in our practice due to its high cost and lack of availability.

Acute Intestinal Occlusions at the Cs Ref of Commune I of Bamako

Acute intestinal obstructions are defined as a complete and persistent cessation of materials and gases in a segment of the digestive tract. They constitute a medical-surgical emergency. Our work aimed to study acute intestinal obstructions, to determine the hospital frequency, to describe the aspects (epidemiological, clinical and therapeutic), to analyze the surgical consequences and to evaluate the cost of the management of obstructions. acute intestinal infections in the general surgery department of the reference health center of commune I of Bamako in Mali. Our retrospective, longitudinal and descriptive study took place from January 1, 2015 to December 31, 2019 in the general surgery department of the reference health center in commune I of Bamako. The average age was 47.72 years with extremes of 15 and 78 years and a standard deviation of 16.07. Our sex ratio (56 men/15 women) was 3.38. The clinical signs were dominated by abdominal pain (100%), vomiting (52.9%), cessation of materials and gases (25.4%) and meteorism (35.3%). The main etiologies found intraoperatively were strangulated hernia (54.9%), bands and/or adhesions (21.1%), sigmoid volvulus (12.7%), colorectal tumor (7%), small bowel volvulus (2.8%) and acute intestinal intussusception (1.4%). Hernia repair was the most performed surgical procedure, i.e. 54.9%. The overall mortality rate was 1.4%.

Reliability of Medical Imaging in the Pre-Therapeutic Assessment of Acute Intestinal Obstruction at the Centre Hospitalier Universitaire Du Point “G”.

Introduction: Acute intestinal obstruction is a serious pathology, a surgical emergency for which medical imaging plays an important role in the management. We initiated this work in order to study the contribution of imaging in the diagnosis of acute intestinal obstruction at the Point-G University Hospital. Patients and Methods: This was a prospective, descriptive and analytical study of 96 patients collected at the radiology and medical imaging department of CHU Point-G from January 2018 to January 2019. Results: The age of our patients varied from 11 to 86 years, with an average of 36 years old. There was a male predominance of 64.6% against 35.4% for women, i.e., a sex ratio of 1.82. Previous surgery was found in 61.5% of our patients. The pain was present in all patients. An unprepared abdominal X-ray was performed in 89.6% of patients. Hydroaerobic levels were found in 96.5% of patients. Abdominopelvic CT scans were performed on 12 patients, all of whom were diagnosed with occlusion. These positive diagnostic findings were consistent with intraoperative findings in 92% of cases. The causes were dominated by bridges in 46 patients and tumors in 9 patients. Signs of severity on CT were dominated by signs of distress of the upstream bile ducts in 8.3%. Exactly 8% of our patients spontaneously resumed transit, 91% received surgical treatment and 1% died before surgery. The outcome was favorable in 80 patients (83.3%) and poor with death in 16 patients (16.7%). Conclusion: Acute intestinal obstruction remains a serious pathology for which the X-ray of the PSA is often the only radiological examination performed in an emergency. However, abdominopelvic CT seems to us to be widely indicated thanks to its contribution both to the positive diagnosis and to the diagnosis of severity and etiology. However, this imaging technique is widely underused in our practice because of its high cost and lack of availability.

A computed tomography-based radiomic model for the prediction of strangulation risk in patients with acute intestinal obstruction

Background We created and validated a computed tomography(CT)-based radiomic model using both clinical factors and the radiomic signature for assessing the strangulation risk of acute intestinal obstruction.This would assist surgeons in accurately predicting intestinal ischemia and strangulation in patients with intestinal obstruction.Methods We recruited 289 patients with acute intestinal obstruction admitted in the Affiliated Hospital of Qingdao University from January 2019 to February 2022.The patients were allocated to a training(n=226)and validation cohort(n=63).Radiomic features were collected from CT images,and the radiomic signature was extracted and used to calculate a radiomic score(Rad-score).A nomogram was constructed using the clinical features and the Rad-score,and the performance of the clinical,radiomics,and nomogram models was assessed in the two cohorts.Results Six robust features were used to construct the radiomic signature.The nomogram incorporating hemoglobin levels,C-reactive protein levels,American Society of Anesthesiologists score,time of obstruction,CT image of mesenteric fluid(P<0.05),and the signature demonstrated good predictive ability for intestinal ischemia in patients with acute intestinal obstruction,with areas under the curve of 0.892(95%confidence interval,0.837–0.947)and 0.781(95%confidence interval,0.619–0.944)for the training and validation sets,respectively.The decision curve analysis showed that this model outperformed the clinical and radiomic signature models.Conclusion The radiomic nomogram may effectively predict intestinal ischemia in patients with acute intestinal disease and may assist clinical decision-making。
