Using an
antiperistaltic agent and oral intake of 250 mL of additional contrast agent immediately before the imaging can improve the quality of the assessment.
The
antiperistaltic contractions were initiated in the PAHG regions anterior to the rectum.
Engaging in intercourse at this time creates
antiperistaltic movements, disturbing the rhythm of the fallopian tubes.
Antiperistaltic agents, such as diphenoxylate (Lomotil[R]) and loperamide (Imodium[R]), are used for treatment of diarrhea; however, they should not be used in patients with high fever or with blood in the stool; these drugs should be discontinued if symptoms persist more than 48 hours.
Antiperistaltic agents (e.g., diphenoxylate and loperamide) can be used for the treatment of mild diarrhea.
No
antiperistaltic agents (e.g., Lomotil and Imodium) are effective in preventing TD.
In some cases, it is has been reported the presence of multiple
antiperistaltic waves of contraction, which produced a corkscrew (Figure 3) esophagus [33].
Intravenous administration of these
antiperistaltic agents has been shown to improve image quality and lesion visualization in oncological pelvic MRI and is recommended for routine use.
The steps in medical treatment are to stop the implicated agent, provide supportive measures, avoid the use of
antiperistaltic agents, and administer specific antimicrobial agents when ordered.
Both vancomycin and metronidazole may be given concurrently.[1,7,11] There is some controversy regarding the use of vancomycin because of the reported increase in vancomycin-resistant enterococci.[12] Oral bacitracin may also provide an adequate response.[4,11] Decompression of the colon by means of rectal tube or endoscopy is important in toxic megacolon, and is an alternative to surgery.[1]
Antiperistaltic agents are contraindicated, as they lead to prolonged illness and development of complications, especially in older patients.
Esophagojejunostomy in FEEA is performed in the
antiperistaltic direction; therefore, the jejunal limb needs to be lifted further up in FEEA than in the overlap method.
Kim and coworkers (2) noted that
antiperistaltic constipation, and not diarrhea, is associated with focal and intense bowel uptake, and significant activity in fecal matter suggests an intraluminal and/or bacterial component to the activity.
