AI Article Synopsis
- Enterobius vermicularis, commonly known as pinworm, typically affects children and causes perianal itching, but it can present in unusual ways in adults.
- A case study describes a man in his 60s who experienced a large-bowel obstruction with severe abdominal symptoms, leading to the discovery of a mass in his colon.
- The patient underwent surgery, and during the procedure, many pinworms were found in his colon, identified as a pseudotumor linked to the infection, showcasing a rare cause for bowel obstructions in adults.
Article Abstract
Enterobius vermicularis infection is typically observed in paediatric patients and manifests with perianal pruritus, but other manifestations or ectopic presentations have been reported in the literature. We present the case of a man in his 60ss with a large-bowel obstruction with symptoms including a 4-day history of progressive abdominal pain, distension, vomiting and absolute constipation. On examination, his abdomen was distended with tinkling bowel sounds on auscultation. Cross-sectional imaging demonstrated an obstructing mass in the distal descending colon. An emergency laparoscopic Hartmann's procedure was performed and the patient made an uneventful recovery. An intraoperative colonoscopy demonstrated numerous white threadworms in the colon. Histological analysis demonstrated a pseudotumour related to Enterobius vermicularis infection. This case represents a rare differential diagnosis for a large-bowel obstruction.

Foreign body granuloma (FBG) is an inflammatory reaction to an exogenous agent. This entity is well known on the cutaneous organ but very rarely described in the abdominal cavity. We report three clinical cases of intraperitoneal FBG following major debulking of pseudomyxoma and intraperitoneal hyperthermia chemotherapy.

Gallstone ileus, a rare cause of mechanical bowel obstruction, occurs due to the formation of a cholecystenteric fistula allowing gallstones to migrate into the gastrointestinal tract. The condition occurs mostly in elderly patients, particularly women, and carries a significant mortality risk due to delayed diagnosis. This case report discusses a 77-year-old female patient with a history of chronic medical conditions, who self-presented with periumbilical pain, nausea, and reduced bowel movements.

Ogilvie syndrome, also known as acute colonic pseudo-obstruction, is a form of colonic dilation occurring without underlying mechanical or anatomic etiology. It is a disorder of imbalance in motor innervation of the large intestine, which causes acute colon obstruction in the absence of any physical obstruction. It is associated with high morbidity and mortality due to diagnostic dilemmas and the need for surgical intervention.

Background: Kaposiform hemangioendothelioma is a rare vascular tumor primarily occurring in infants and children. The most common sites for kaposiform hemangioendothelioma are extremities, with very few cases of abdominal kaposiform hemangioendothelioma reported in neonates. Making a diagnosis of Kaposiform hemangioendothelioma can be challenging when the patient presents with generalized symptoms such as bilious vomiting and constipation that can be attributed to other more common causes of intestinal obstruction.
