Abstract
Endoscopic removal of premalignant polyps can prevent colorectal cancers. It is considered a safe procedure, yet there are some complications reported. Rectus abdominis muscle abscess (RAMA) is a type of pyomyositis seen as a complication of rectus sheath hematoma. Predisposing factors to RAMA include trauma, diabetes mellitus, alcohol abuse, Intravenous drug abuse and hematologic diseases.In this article, we report a case of a 74-year-old patient with abscess formation in the Rectus Abdominis muscle after colonoscopy and polypectomy with the application of abdominal pressure techniques without any early complications. Diagnosis of RAMA was made after a Computed Tomography scan and ultrasound-guided drainage, in addition to antibiotic therapy, were used as treatment.Although colonoscopy is considered a generally safe procedure, endoscopists should be aware of Rectus Abdominis sheath hemorrhage and RAMA in the following as a complication with the presentation of abdominal pain. Applying abdominal pressure should be done carefully To reduce minor trauma likelihood, owing to it being a predisposing factor of RAMA.
