Colonic perforation during barium enema in a patient without known colonic disease: a case report

The barium enema is a safe and accurate diagnostic study of the colon but, in rare cases, causes complications, such as colonic perforation. A colon weakened by iatrogenic trauma due to the enema tip and/or retention balloon, or by disease is more likely to perforate during an enema than is a normal healthy bowel. Rarely the colon may burst due to excessive transmural pressure alone. We report a case of colonic perforation during barium enema in a 72-year-old female patient, due to excessive barium applied into the rectum

Perforated mixed carcinoid-adenocarcinoma in transverse colon and at gastroenterostomy site: case report

Goblet cell carcinoid of the large intestine is a rare neoplasm, usually located in ascending colon and rectum. A 60-year-old male patient underwent surgery after the diagnosis of acute abdomen. Exploratory laparotomy revealed perforation with a diameter of 1 cm at the site of the previously performed gastroenterostomy and dilatation of the right colic flexure, secondary to a solid obstructive mass located in the mid-portion of transverse colon. Histopathological investigation of the biopsies, taken from the gastroenterostomy site and the tumor, revealed mixed carcinoid-adenocarcinoma with carcinoid component, predominantly composed of goblet cells. Three cycles of FOLFOX-4 protocol was administered. Following respiratory distress secondary to pulmonary metastasis, the patient's condition deteriorated and subsequently died in the fourth postoperative month. Our aim with this paper is to point out that more cases should be reported for more effective diagnosis, histopathological study, clinical investigation, treatment and prognosis of this specific neoplasm

Esophagectomy in esophageal lipoma: Report of a case

Lipoma is an uncommon benign tumor of the alimentary tract and its overall incidence is 4.1%, but that of the esophagus is extremely rare, with an incidence of only 0.4%. We present a case of esophageal lipoma. A 55-year-old man had a two-year history of dysphagia and odynophagia. Upper gastrointestinal system endoscopy showed a mass in the wall of the esophagus, occupying the lumen, and causing obstruction. Computed tomography and abdominal ultrasonography were performed because of endoscopic suspicion of submucosal tumor, and the mass was confirmed to be a lipoma in the wall of the esophagus. It was removed surgically by a thoracic approach. His symptoms resolved after the operation. Surgical excision by enucleation of the tumor is the preferred treatment of esophageal lipoma, but opening of the esophageal mucosa during this procedure is a rare cause for esophageal resection

Small cell carcinoma of rectum: A case report

We present a case of a 40-year-old woman with small-cell carcinoma (SCC) of the rectum. She had profuse bleeding in rectum for 5 d. By colonoscopy, polyps were determined in the rectum and biopsies were carried out. Histopathologically, the polyps were adenomatous. Because of the profuse bleeding in rectum, she underwent low anterior resection. After the diagnosis of SCC, she received intravenous chemotherapy with standard doses of siklofosfamid, adriamycin, and vepesid. Nevertheless, intracranial metastases were revealed and she died 6 mo after the operation
