“…It was proved that this method performed effectively in the detection of intestinal obstruction, although the preferred imaging modality for intestinal obstruction is anteroposterior abdominal radiography. Its role in diagnosis is quite limited due to the differences among interpreters, the limited information it provides about the etiological factor of intestinal obstruction [ 238 ], and the overlap of abdominal tissues and organs in abdominal radiography [ 239 ]. Magnetic resonance imaging does not currently play a large role in the detection of obstruction, but it remains investigational because of the costs of CT scanning.…”

“…Another sensitive imaging for bowel obstruction is computed tomography. It is most effective in high-grade obstruction, but it can detect various levels of obstruction, the location of transition points, and the presence of closed-loop obstruction and complications [ 238 ], in addition to the causes of the obstruction. Based on the meticulous interpretation of images, CT findings may be pivotal in determining surgical intervention [ 238 ].…”

Gastrointestinal (GI) disorders comprise a diverse range of conditions that can significantly reduce the quality of life and can even be life-threatening in serious cases. The development of accurate and rapid detection approaches is of essential importance for early diagnosis and timely management of GI diseases. This review mainly focuses on the imaging of several representative gastrointestinal ailments, such as inflammatory bowel disease, tumors, appendicitis, Meckel’s diverticulum, and others. Various imaging modalities commonly used for the gastrointestinal tract, including magnetic resonance imaging (MRI), positron emission tomography (PET) and single photon emission computed tomography (SPECT), and photoacoustic tomography (PAT) and multimodal imaging with mode overlap are summarized. These achievements in single and multimodal imaging provide useful guidance for improved diagnosis, staging, and treatment of the corresponding gastrointestinal diseases. The review evaluates the strengths and weaknesses of different imaging techniques and summarizes the development of imaging techniques used for diagnosing gastrointestinal ailments.

“…Despite advances in medicine, the diagnosis of morphological changes in the small intestine due to non-ischemic and ischemic injuries in diseases such as acute intestinal obstruction, mesenteric occlusive and non-occlusive ischemia, and strangulated ventral hernia before surgery remains one of the most difficult problems in emergency abdominal surgery. Most studies have shown that the common leading causes of adverse outcomes in most cases in this category of patients is metabolic damage precipitated by an unbalanced response of the body to ischemia/necrosis of the small intestine and infection, which often leads to organ dysfunction, the development of peritonitis, and abdominal sepsis [1,2]. It should be noted that at least 300,000 operations for small bowel obstruction are performed annually in the United States alone [3], and about 40% of cases are associated with strangulation and necrosis of the small intestine.…”

Background: Small bowel obstruction, mesenteric thrombosis, and strangulated ventral hernia area a challenge in emergency abdominal surgery. This study aimed to evaluate biomarkers of damage to the digestive tract in patients with urgent pathology. Materials and methods: The study involved 71 patients aged 18 to 80 years who were hospitalized in the intensive care unit in the immediate postoperative period. Results: All 71 underwent emergency surgery, 27 with small bowel necrosis. Lactate level area under curve (AUC = 0.964), C-reactive protein (AUC = 0.805) and systolic blood pressure (area under curve, AUC = 0.803) on the context of Sequential Organ Failure Assessment (SOFA) score (AUC = 0.880) showed stratification of patients with complications before surgery. Small bowel necrosis patients revealed an increase in primary thiobarbituric acid (TBA) reactive products (AUC = 0.813) lipid peroxidation products, and a decrease in superoxide dismutase activity (AUC = 0.818) and catalase (AUC = 0.804). Wide variability of intestinal fatty-acid binding protein (I-FABP) from 199.8 to 2189.6 pg/mL were observed in all patients studied, with an AUC = 0.814 in small intestinal necrosis. Conclusion: Surgical pathology of the small intestine due to obstruction of various origina, mesenteric thrombosis, and strangulated ventral hernia pronounced revealed disorders of the antioxidant-prooxidant balance. This was expressed by an increase in lipid peroxidation products, and the level of TBA-reactive products, and the activities of superoxide dismutase (SOD), and catalase. Viewed against the background of an increase in I-FABP above 577 pg/mL, these variables were the most significant indicators of small intestinal necrosis.

“…Clinically, the most important findings are abdominal pain, vomiting, swelling in the stomach, a decrease in gas and stool. While the abdominal pain is initially in a colic style, it becomes permanent due to the decrease of peristaltism in the following period [5] . Plain films are usually obtained initially and have overall 69%, 57%, and 67% sensitivity, specificity, and accuracy, respectively [6] .…”

To evaluate the role of Multidetector computed tomography in clinically suspected acute small bowel obstruction. Material and methods:The present prospective observational study was on 50 patients with clinical suspicion of acute small bowel obstruction referred to Department of Radio diagnosis, Imaging and interventional radiology from OPD/IPD of C.S.S. Hospital, under the age is of N.S.C.B Subharti Medical College, Meerut. After obtaining clinical history relevant clinical examination was done. CT examinations were done on Philips Ingenuity 128 Slice (MDCT). Imaging and Diagnosis of Small Bowel Obstruction was made as per departmental protocols. We then assessed whether obstruction was present and if present, the level, cause of the obstruction and small bowel feces sign were assessed. Results: 56% of the patients were operated surgically for the management of the SBO while 44% of the subjects were managed conservatively. CT diagnosis predicted true positive and true negative cause of obstruction among 60.71% and 17.86% of the cases while false positive and false negative among 7.14% and 14.29% of the cases. CT diagnosis predicted true positive and true negative finding for the site of obstruction among 57.14% and 25% of the cases while false positive and false negative among 10.71% and 7.14% of the cases. Conclusion: MDCT is highly sensitive and specific in diagnosing cause of obstruction. In addition to primary gut pathology, MDCT can detect various associated and incidental findings which are not suspected clinically.
