“…11 On examination, the patient may appear dehydrated and have active, high-pitched bowel sounds, though abdominal auscultation generally has poor sensitivity and specificity for bowel obstruction. 12 Abdominal radiographs can help to identify SBO in 50–60% of cases and is often performed as the initial imaging tool because of its relatively low expense and radiation exposure. 11…”

Complete small bowel obstruction (SBO) is a common surgical emergency often resulting from adhesive bands that form following iatrogenic peritoneal injury. Rarely, adhesive SBO may arise without previous intra-abdominal surgery through other modes of peritoneal trauma. We present the case of a male evaluated in the emergency department for a closed-loop small bowel obstruction due to an adhesive band that likely formed after blunt abdominal trauma over two decades earlier. We review the epidemiology, pathophysiology, and treatment options for similar cases of adhesive SBO.

“…However, using a handheld stethoscope for auscultation is still the main way to quickly obtain intestinal sounds in the clinic. As for the identifying the specific gut sounds, the results tend to be random and depend on of subjective judgment and are therefore questionable [8,9]. In the study of BSs, the sounds are acquired by means of an assembly of mature pickups and storage units.…”

Background: General anesthesia can affect intestinal function, but there is no objective, practical and effective indicator to evaluate the inhibition and recovery of intestinal function. The main objectives of this study were to assess whether bowel sounds (BSs) changed before, immediately after and 3 hours after general anesthesia, and whether these changes in BSs are an effective indicator of intestinal function and an accurate guide for post-operative feeding. Methods: We randomly selected 26 inpatients and collected three sets of 5-minute continuous BS data before the operation (Pre-op), immediately after the operation (Pro-op) and three hours after the operation (3h-Pro-op) for each patient. Then the linear and nonlinear characteristic values (CVs) of each EBS were extracted and paired t -tests and rank-sum tests were used to evaluate the changes in the BSs. Results: The differences in CVs, between Pre-op and Pro-op, as well as between Pro-op and 3h-Pro-op, were statistically significant ( p <0.05). However, there is no statistically significant differences between all the CVs between Pre-op and 3h-Pro-op ( p >0.05). Conclusion: BSs changes before and after general anesthesia. Furthermore, the BSs are weakened due to general anesthesia and recover to the pre-op state three hours later. Therefore, the BSs can be an indicator of intestinal function under general anesthesia, so as to provide guidance for postoperative feeding , which is of considerable clinical significance.

Accuracy of abdominal auscultation for bowel obstruction

Abstract: Accuracy and inter-observer agreement was generally low. Clinical decisions in patients with possible bowel obstruction should not be based on auscultatory assessment of bowel sounds.
