==Background==
*Over 85% of the serious colonoscopy complications are reported in patients undergoing colonoscopy with polypectomy (7-fold increase)<ref>Complications of colonoscopy. GASTROINTESTINAL ENDOSCOPY Volume 74, No. 4 : 2011</ref>

==Clinical Features==
*Hemorrhage
**Most common complication
**Caused by polypectomy, biopsy, mucosal lacerations, mesenteric or splenic tears
**[[Rectal bleeding]] (if intraluminal)
**Intra-abdominal bleed (if mesenteric or [[splenic trauma]])
*Perforation
*Post-polypectomy electrocoagulation syndrome
**peritoneal inflammation without frank perforation
**[[abdominal pain]], [[fever]], [[leukocytosis]]
*[[Infection]]: bacteremia, retroperitoneal abscess, [[appendicitis]]
*Colonic distension, precipitation of [[toxic megacolon]]
*[[Myocardial infarction]], [[PE]] (if off anticoagulation)
*Gas explosion
**methane (in flatus) + electrocautery → BOOM!

==Differential Diagnosis==
{{Lower GI bleeding DDX}}
{{Abdominal Pain DDX Diffuse}}

==Evaluation==
*CBC
*Coags, T&S if bleeding
*[[CXR]] for free air if concern for perforation
*CT abdomen/pelvis (if presentation concerning for intra-abdominal bleed, infection, or perforation)

==Management==
*[[PRBC]] transfusion, reverse coagulopathy if significant bleed
*Surgery (or IR) consult for possible laparotomy if concern for intra-abdominal bleed, perforation, or abscess 
*Antibiotics if concern for perforation or infection
**See [[peritonitis]]
