Intravenous Contrast Agent

Background. To compare sensitivity of unenhanced computed tomography (CT) and contrast-enhanced CT for the identification of the etiology of bowel obstruction. Materials and Methods. We retrospectively evaluated abdominal CT scans of patients operated for bowel obstruction from March 2013 to October 2017. Two radiologists evaluated CT scans before and after contrast agent in two reading sessions. Then, we calculated sensitivity of CT in the diagnosis of bowel obstruction and determined in which cases the etiology of bowel obstruction was detected on both unenhanced and enhanced CT or on enhanced CT only. The reference standard was defined as the final diagnosis obtained after surgery. Results. Eighteen patients (mean age 72±15 years, age range 37-88 years) were included in the study. Sensitivity of unenhanced CT and enhanced CT was not significantly different in either small bowel obstruction (64%, 7/11 patients vs. 73%, 8/11 patients; P=0.6547) or large bowel obstruction (71%, 5/7 patients vs. 100%, 7/7 patients; P=0.1410). Adhesions were identified on unenhanced CT as the etiology of small bowel obstruction in 80% (4/5) of patients. Tumors were identified on unenhanced CT as the etiology of large bowel obstruction in 67% (4/6) of patients. Conclusion. In the diagnosis of small bowel obstruction due to adhesions with normal bowel wall thickening and when a neoplasm is identified as the etiology of large bowel obstruction on unenhanced CT, an intravenous contrast agent may be avoided for the identification of the etiology. In remaining cases, contrast agent is still recommended.

Haemangiomas of the small bowel are a very rare entity and rarely considered as an aetiology for an intestinal obstruction. Contrast-enhanced CT is the investigation of choice but the lesion can be confused with malignancy or rarely a neuroendocrine tumour. Commonly it presents as abdominal pain with anaemia and/or melaena. With patients presenting without obstruction or acute gastrointestinal bleed, capsule endoscopy has shown to be a useful diagnostic tool.We present here our experience of managing a case of a patient with ileal haemangioma who presented with a subacute small bowel obstruction and underwent a laparoscopic-assisted ileal segmental resection with side-to-side anastomosis. The lesion was a cavernous haemangioma on histopathological analysis.

History Of

Adhesion band is a major cause of small bowel obstruction. Traditionally, the obtained results of computed tomography (CT) scan were indicative of adhesion band as an etiology for small bowel obstruction. However, adhesion is easily diagnosed today due to technological advances in radiology and high-quality multidetector CT. It is important to avoid the possible complications of bowel obstruction in the early and appropriate surgical intervention. This article is a report of a 45-year-old woman with abdominal pain and history of previous abdominal surgery. A contrast-enhanced CT scan showed multiple adhesion bands ensued the abrupt narrowing of bowel diameter and closed small-bowel loops obstruction. Furthermore, multiple bands were clearly observed and adhesiolysis was performed in the surgery.

Patient Presentation

Internal herniation following laparoscopic surgery is rare. We present a case of small bowel obstruction secondary to internal herniation in a 76-year-old male patient. Presentation was on postoperative day 28 following transperitoneal laparoscopic radical left nephrectomy for suspected renal carcinoma. The herniation was through a defect in the large bowel mesentery identified at exploratory laparotomy. To date, 10 cases of internal herniation following laparoscopic nephrectomy have been described in the literature. Two cases were managed laparoscopically and the remainder by laparotomy. One case required resection of an ischaemic portion small bowel and the remainder were managed by reduction of the hernia and closure of the defect. Internal herniation is rare but carries significant morbidity. It must be considered in cases presenting with obstructive symptoms after laparoscopic nephrectomy. Early CT scanning and prompt surgical management are hallmarks of best management.

Initial Imaging

Small bowel obstruction (SBO) is a common condition requiring urgent attention that may involve surgical treatment. Imaging is essential for the diagnosis and characterization of SBO because the clinical presentation and results of laboratory tests may be nonspecific. Ultrasound is an excellent initial imaging modality for assisting physicians in the rapid and accurate diagnosis of a variety of pathologies to expedite management. In the case of SBO diagnosis, ultrasound has an overall sensitivity of 92% (95% CI: 89–95%) and specificity of 93% (95% CI: 85–97%); the aim of this review is to examine the criteria for the diagnosis of SBO by ultrasound, which can be divided into diagnostic and staging criteria. The diagnostic criteria include the presence of dilated loops and abnormal peristalsis, while the staging criteria are represented by parietal and valvulae conniventes alterations and by the presence of free extraluminal fluid. Ultrasound has reasonably high accuracy compared to computed tomography (CT) scanning and may substantially decrease the time to diagnosis; moreover, ultrasound is also widely used in the monitoring and follow-up of patients undergoing conservative treatment, allowing the assessment of loop distension and the resumption of peristalsis.
