OBJECTIVE To analyze, through molecular biology, the diversity of the intestinal microbiota before and after resection of the ileocecal junction and reconstruction of intestinal transit with and without the creation of a neosphincter. METHODS Fourteen Wistar rats were divided into two groups: Group A (n = 7), submitted to resection of the ileocecal valve and end-to-end, single-layer ileocolic...

Adenocarcinoma as the primary cause of bowel intussusception is uncommon. We describe case a 86-year-old patient admitted for ileocecal due to presence adenocarcinoma, located in valve and right colon. The etiologies intussusception, its diagnosis, conservative or surgical treatments are discussed, with attention placed on indications reduction invagination prior resection.

abstract bowel obstruction is a known complication after bariatric surgery especially roux-en-y gastric bypass. the known etiologies include internal hernia, jejunojejunostomy stricture, ileus, intussusceptions, superior mesenteric artery syndrome, incarcerated port site hernia, and adhesions. blood clot is a rare cause of small intestinal obstruction after laparoscopic roux-en-y gastric bypass...

BACKGROUND Carcinoma of the colon may present with perforation proximal to the site of malignancy. Caecum is the commonest site of perforation if the ileocecal valve is patent and the jejunal and ileal perforations are very rare. CASE PRESENTATION A 35 year male presented with intestinal obstruction. Emergency laparotomy revealed carcinoma of the transverse colon with multiple pinpoint perfor...

Granular cell tumors (GCTs) have been described as neoplasms of Schwann cell origin. They are often benign and notably uncommon in the gastrointestinal tract. Recently, their incidence has become more common, likely as a result of increased colonoscopy screenings. Very few data exist regarding their potential for malignancy, but malignant GCTs have been reported. Here, we report the case of a y...

CASE REPORT The case of a breast cancer patient with a progressive increase of CA 19.9 that indicated gastrointestinal metastasis is reported. After the observation of an increased CA 19.9 serum value (104.00; n.v. 0.0-37.00) a colonoscopy was performed. This examination showed the presence of an erythematous and granular zone near the ileocecal valve. Histological examination of biopsies taken...

INTRODUCTION Colonic lipomas are relatively common but they rarely progress to complete acute obstruction. CASE OUTLINE We report a case of a 67-year-old woman with acute intestinal obstruction caused by a large pedunculated lipoma of the ileocecal valve. Preoperatively, the patient presented acutely with clinical and radiographic signs of small intestine ileus. A right hemicolectomy with sub...

Ingestion of foreign bodies and particularly of button or/and cylindrical batteries is frequent in children and adults with underlying psychiatric diseases. We present a case of a 30-year-old woman with unstable borderline disorder, where overall 4 button and 2 cylindrical batteries were endoscopically removed from her digestive system. During the last session of colonoscopy a peculiar incident...
