An uncommon problem: Overcoming the challenges of rectal foreign bodies—A case series and literature review

Abstract

Key Clinical Message Although rectal foreign bodies are rare presentations, this condition should be considered in patients with preanal pain, lower pelvic pain, or rectal bleeding. Abstract Rectal foreign bodies are a rare occurrence and can pose a therapeutic challenge for surgeons. These objects may be inserted through the anus or ingested orally. This study presents a retrospective review of all cases of trapped rectal foreign bodies at a single university hospital. From 2001 to 2020, twelve cases of rectal foreign bodies were diagnosed and treated at Ghaem Hospital in Mashhad. Demographic information, type of foreign body, clinical presentation, and removal method were collected retrospectively. All cases of rectal foreign bodies entered through the anus. Twelve cases involved male patients, with a mean age of 47.5 years (ranging from 24 to 70 years), and two cases involved female patients, with a mean age of 29.5 years (ranging from 29 to 30 years). Patients' main complaint was defecation disorder, accounting for 57% of cases. The types of rectal foreign bodies included two body sprays, two wood pieces, two glass bottles, glasses, eggplants, cucumbers, squash, and anal dilators. One case involved surgical gas. In five cases, rectal foreign bodies were removed under general anesthesia through the rectum by dilatation. Rectal foreign bodies were removed by rectosigmoidoscopy in three cases, forceps in two cases, and abdominal maneuvers in one case. Only one case required laparotomy. Minor complications such as scratches or small mucosal tears were observed in some cases after removal of the foreign body, but no deaths were reported. Although rectal foreign bodies are rare, this condition should be considered in patients with preanal pain, lower pelvic pain, or rectal bleeding when no justification for recent endoscopic examinations is found. Most rectal foreign bodies are removed through the anus under appropriate anesthesia. Rectosigmoidoscopy is a good alternative if needed. Surgical measures are necessary for cases that lead to peritonitis or are likely to cause serious injury.
