| ==Overview==
| |
| '''Proctocolitis''' is a general term for [[inflammation]] of the [[rectum]] and [[Colon (anatomy)|colon]] particularly distal part of the colon([[sigmoid]])<ref>Online Medical dictionary[http://cancerweb.ncl.ac.uk/cgi-bin/omd?proctocolitis]</ref>. Common causes of proctocolitis include ''[[Chlamydia trachomatis]]'', ''[[Lymphogranuloma Venereum]]'', ''[[Neisseria gonorrhoeae]]'', [[Herpes Simplex Virus|HSV]], and [[Campylobacter]] species. The mainstay of therapy for proctocolitis is [[antimicrobial]] therapy. The preferred regimen is a combination of [[Ceftriaxone]] and [[Doxycycline]].

| | |
| ==Historical Perspective==
| |
| | |
| ==Classification==
| |
| There is no established classification system for proctocolitis. However, proctocolitis may be classified based on causality into
| |
| *[[Infectious]]
| |
| *Non-infectious
| |
| *Infectious proctocolitis may be viral, bacterial, fungal, protozoan, and atypical micro-organism.
| |
| *Non-infectious proctocolitis may be allergic (eosinophilic), vascular, autoimmune, drug-induced, radiation, chemical, and idiopathic.
| |
| | |
| ==Pathophysiology==
| |
| | |
| ==Causes==
| |
| Proctocolitis has many possible causes. Common infectious causes of proctocolitis include ''[[Chlamydia trachomatis]]'', [[Lymphogranuloma Venereum|LGV (Lymphogranuloma Venereum)]], ''[[Neisseria gonorrhoeae]]'', [[Herpes Simplex Virus|HSV]], and [[Campylobacter|Campylobacter species]]. It can also be idiopathic (see [[colitis]]), vascular (as in [[ischemic colitis]]), or autoimmune (as in [[inflammatory bowel disease]]).
