Abdominal Surgery in Crohn's Disease: Risk Factors for Complications.

Introduction: Abdominal surgery in patients with Crohn's disease (CD) is challenging, especially in the biologic era. The aim of this study was to evaluate factors associated with increased risk for postoperative complications in CD.

Methods: A retrospective study was conducted with consecutive patients who underwent abdominal surgery for CD from January 2012 to January 2018.

Mucinous adenocarcinona of the appendix.

Diagnosis of malignancy in the vermiform appendix is quite rare. The most common histological malignant neoplasia found in this tiny portion of the gastrointestinal tract is represented by the mucinous adenocarcinoma. This entity predominates in males around 50 years of age, and clinical presentation usually mimics or occurs along with an acute appendicitis.

Concurrent development of Crohn disease and myelodysplastic syndrome in a child: case report and literature review.

A small number of cases of Crohn disease associated with myelodysplastic syndromes or leukemia have been reported in adults in the last 25 years in the English-language medical literature. The authors report a case of a 9-year-old boy who developed Crohn disease and myelodysplastic syndrome concurrently. Analysis of his bone marrow showed a chromosome 20 abnormality.

Effects of enalaprilat on the renin-angiotensin-aldosterone system and on renal function during CO2 pneumoperitoneum.

Background And Purpose: Mechanical and hormonal factors have been implicated in pneumoperitoneum-induced renal alterations. The aim of this study was to evaluate the effects of enalaprilat (Vasotec) administration on renal function during CO2 pneumoperitoneum, given that this drug, which is an angiotensin-converting enzyme inhibitor, by inhibiting the renin-angiotensin-aldosterone system, alters hormone-induced changes during pneumoperitoneum.

Materials And Methods: Thirty adult dogs were randomly assigned to one of three groups (N = 10 each): group A (pneumoperitoneum not performed); group B (CO2 + enalaprilat); group C CO2 only.

Stapled hemorrhoidectomy for the treatment of hemorrhoids.

Background: The use of circular staplers in the treatment of hemorrhoidal disease is known as a simple procedure, with low morbidity, less post-treatment pain and with the same efficacy when compared to the classical hemorrhoidectomy.

Aim: Analyze the operative technique, intra-operative and immediate postoperative complications and late results in 100 patients treated for hemorrhoid disease by stapling technique.

Patients And Methods: The group included 53 males and 47 females with mean age of 49.
