[Gastroduodenal trichobezoar: about a case]. / Trichobézoard gastroduodénal: à propos d'un cas.

Gastroduodenal trichobezoar ulcer is rare. Its diagnosis is easy in the presence of an evocative context. We report the case of a 21-year old patient followed up for schizophrenia, admitted with acute abdominal pain, vomiting and epigastric mass. Abdominal CT scan suggested the diagnosis of bezoar on the basis of heterogeneous, non-enhanced lesions occupying the entire stomach and appearing to be separated from the gastric wall. Surgical removal of trichobezoar by gastrotomy was performed without complications. The patient was referred to the Department of Psychiatry.

[Volvulus of the cecum: a rare cause of intestinal occlusion: about two cases]. / Volvulus du cæcum: une cause rare d'occlusion intestinale: à propos de deux cas.

The cecum is the second part of the colon that is most commonly affected by the volvulus after sigmoid colon and before left corner and the transverse colon. This condition occurs in patients with abnormally mobile cecum. Volvulus is characterized by torsion or tilt. Clinically, it appears as bowel obstruction due to acute strangulation. Abdominal x-ray without treatment and abdominal CT scan are the radiological procedures of choice in the diagnosis of volvulus of the cecum. Treatment is based on emergency surgical excision of the cecum and of the terminal ileum. We report two cases of patients with volvulus of the cecum admitted to the emergency department with acute intestinal obstruction. In both patients, the diagnosis was confirmed by abdomino-pelvic CT scan and the treatment was based on ileocolic resection with immediate restoration of the intestinal continuity. The postoperative course was uneventful.
