Taenia saginata: an unusual cause of post-appendectomy faecal fistula.

Post-appendectomy faecal fistula is a rare surgical complication, associated with significant morbidity. Taenia saginata infestation is one of the most common cestode infestation in the gastrointestinal tract. It makes many complications as obstruction, perforation, anastomotic leakage or appendicular stump dehiscence. The objective of our study is to report a very rare case of post appendectomy faecal fistula caused by taenia saginata infestation and was successfully treated conservatively.

Invasive amebiasis.

Digestive amoebiasis with his invasive form is an unusual pathology encountered in the temperate zone. This could lead to a life threatening complication: systemic amoebiasis. A 55-year-old male was treated successfully of systemic amoebiasis in a third referral hospital. The diagnosis was established based on epidemiology data and microscopical identification of trophozoites of Entamoeba histolytica. The amoebicidal, antibiotic and supportive treatments was firstly administrated. The clinical picture of intestinal amoebiasis raised from dysenteric syndrome to necrotizing enteritis. The bowel perforation with localized peritonitis was followed by chronic enteric fistula. Amoebic liver abscess, as the most frequent extraintestinal complication, was concomitantly diagnosed and treated. Urinary amoebiasis was considered as complication in the context of systemic dissemination: any other location could become a site of an amoebic abscess. Multidisciplinary approach was the successful key in the management of the patient, including antiparasitic therapy and antibiotic prophylaxis, intensive care and multiple surgical approaches. The diagnosis of digestive amoebiasis and systemic complication may be delayed in nonendemic areas, leading to advanced and complicated stages of the disease. The surgical approach is most efficiently to treat a large liver amoebic abscess and intraperitoneal collections.

Ternidens deminutus infection: first pathological report of a human case in Asia.

This is a report of Ternidens deminutus infection in a 33 year old Thai female who was admitted to the hospital because of abdominal pain and a right lower quadrant mass. Exploratory laparotomy revealed an omental mass with attached terminal ileum. Resection of the mass together with the terminal ileum and the right sided colon was performed. Pathologically, the omental mass was an abscess with an immature male Ternidens deminutus identified. The parasite usually is found in the intestine of primates in Africa and Asia. Human infection occurs when food contaminated with infective filariform larvae is ingested. The larvae molt in the intestinal wall and become adults. They pass eggs in feces. Eggs in contaminated soil hatch and become rhabditiform larvae and then infective filariform larvae.

Cytologic diagnosis of Enterobius vermicularis eggs in an enterocutaneous fistula.

A middle-aged female underwent a laparotomy for suspected ovarian cancer and developed a discharging sinus in the right iliac fossa. Smears of the discharge showed helminthic eggs which were characterised as those of Enterobius Vermicularis. The possibility of an enterocutaneous fistula was suggested which was subsequently confirmed during a relook laparotomy.

[Peritoneal hydatidosis with fistulization into the sigmoid colon]. / Hidatidosis peritoneal fistulizada a sigma.

A case is presented of peritoneal hydatidosis with fistulization into the sigmoid in a patient who had previously undergone surgery for hepatic hydatidosis. The clinical picture made its debut as an alteration in intestinal habit followed by the appearance of diarrheic syndrome and expulsion of hydatid membranes. The natural history of peritoneal hydatidosis, its complications and therapeutic guidelines are discussed.

[Spontaneous stercoral fistula due to oxyurids: apropos of 1 case]. / Fistule stercorale spontanée à oxyures : à propos d'un cas.

A spontaneous stercoral fistula containing pinworms was observed in a patient, 35 years after an appendicectomy. The various surgical complications of oxyuriasis are reviewed, in particular, the possibilities for the parasite to traverse the intestinal wall. In the case reported here, it appears that infiltration occurred in the external wall of the caecum.
