CT imaging findings of epiploic appendagitis: an unusual cause of abdominal pain

2019

AbstractEpiploic appendagitis is a rare cause of acute abdominal pain, determined by a benign self-limiting inflammation of the epiploic appendages. It may manifest with heterogeneous clinical presentations, mimicking other more severe entities responsible of acute abdominal pain, such as acute diverticulitis or appendicitis. Given its importance as clinical mimicker, imaging plays a crucial role to avoid inaccurate diagnosis that may lead to unnecessary hospitalization, antibiotic therapy, and surgery. CT represents the gold standard technique for the evaluation of patients with indeterminate acute abdominal pain. Imaging findings include the presence of an oval lesion with fat-attenuation…

De Garengeot Hernia: Case Report and Review of the Literature of a Rare Femoral Hernia

2021

AbstractDe Garengeot hernia is a rare femoral hernia defined as the presence of the appendix within the femoral hernia sac. The incidence of appendicitis in this type of hernia is a rare condition that accounts for 0.08–0.13% of all De Garengeot hernias. We describe the case of a 61-year-old woman that presented at the emergency department with a tender mass (diameter 10 × 8 cm) in the right groin region for 5 days associated with pain in lower right abdomen and accompanied by fever (38 °C). Computed tomography (CT) of the abdomen revealed the presence of a complex fluid collection with small foci of air in the right inguinal region, measuring 9 × 7 × 10 cm in the 3 orthogonal dimensions an…

Long-term outcome after urinary diversion using the ileocecal segment in children and adolescents: Complications of the efferent segment.

2016

Long-term outcomes are of special concern in children after urinary diversion. In a single institution study we evaluated retrospectively the long-term outcomes of urinary diversion in children, in whom the ileocecal segment had been used, in respect to complications of the efferent segment.The Mainz pouch was used in 107 children for continent urinary diversion. Indications were neurogenic bladder (53%, 57/107), exstrophy-epispadias complex (25%, 27/107), malignancy (13%, 14/107), and others (9%, 9/107). Continent cutaneous diversion was performed in 95 patients, and 12 patients received bladder augmentation/substitution with a continent cutaneous stoma. As efferent segment, we used the in…

Continent diversion with the Mainz pouch.

1996

From 1983 until July 1994, 561 patients in 2 urology departments (Mainz and Wuppertal) underwent a Mainz pouch 1 procedure. The Mainz pouch 1 was used for bladder augmentation in 60 patients, for orthotopic bladder substitution in 61 patients, and for continent cutaneous urinary diversion in 440 patients. In the group of continent cutaneous urinary diversion, the continence mechanism applied was an ileal intussusception nipple in 270 patients, an appendix stoma in 146 patients, a submucosal seromuscular bowel-flap tube in 14 patients, and a submucosal full-thickness bowel-flap tube in 10 patients. Indications for urinary diversion were bladder cancer in 339 patients, anatomical or functiona…

Appendiceal continence mechanisms in continent urinary diversion.

1996

The creation of a safe, reliable, and easy-to-perform continence mechanism remains one of the most important problems during continent urinary diversion. The advent of the use of the appendix as an efferent segment brought through the umbilicus has greatly facilitated surgical procedures with very favorable results. Our experience with the insitu appendix as an efferent segment during continent cutaneous urinary diversion using the Mainz-pouch I technique over the past 6 years revealed a markedly decreased complication rate of 3.2% as compared with 7.2% in patients who received an ileocecal intussusception nipple. The routine use of the appendix as a continence mechanism during continent ur…

An atypical clinical presentation of acute appendicitis in a young man with midgut malrotation

2007

Abstract Midgut malrotation occurs as a result of failure in normal intestinal rotation and fixation during early pregnancy. Pathological conditions reported in the literature involving midgut malrotation predominantly relate to infants and children. In adults malrotation is often revealed as an incidental finding on computed tomography (CT), or the associated altered anatomy can be the cause of atypical clinical symptoms of relatively common intestinal disorders. An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT sc…

Multiple Congenital Colonic Stenosis: A Rare Gastrointestinal Malformation

2016

Congenital colonic stenosis is a rare pediatric condition. Since 1968, only 16 cases have been reported in the literature. To the authors’ knowledge, multiple congenital colonic stenosis has not been previously reported in the literature. We report the case of a 2-month-old male, presented at our Neonatal Intensive Care Unit with a suspicion of intestinal malrotation. Clinical examination revealed persistent abdominal distension. During the enema examination, the contrast medium appeared to fill the lumen of the colon up to three stenotic segments and could not proceed further. Intraoperatively we confirmed the presence of four types of colonic atresia, located in the ascending, transverse,…
