[Emergency treatment and diagnosis of appendix mucocele].

The Authors report a case of appendicular mucocele admitted in an emergency setting in the Emergency Department (DEA II). The patient, 78 y-old man, went to attention complaining diffuse abdominal pain: physical examination revealed mild tenderness and right lower quadrant pain to palpation. Rx plain and CT scan demonstrated a right iliac fossa cystic lesion with mural calcification, adherent to the caecum. On basis of imaging, clinical and laboratory findings the patient underwent surgery postoperative diagnosis was mucocele of the appendix. The aim of this report is to discuss the role of imaging and clinical approach in treatment of appendicular mucocele, which is known to be so aspecific in presentation, especially when it occurs in an emergency setting.

Retroperitoneal perforation of the appendix presenting as right thigh abscess.

A case of retroperitoneal perforation of the appendix presenting with a thigh abscess is described. The patient presented with pyrexia (38 degrees C) and abdominal and right thigh pain. There was tenderness in the right loin. His white blood cell count was 22 x 10(9)/L. An intravenous urogram revealed tapering of the right ureter at the L2/L3 level and suggested an infected obstructive uropathy. The patient failed to respond to drainage and antibiotics, so we performed a computed tomography scan, which showed a retroperitoneal abscess extending to the gluteal region and thigh, with signs of small bowel obstruction. This precipitated surgery. The route of extension of infection was through the sacrosciatic notch, which is considered to be a rare way of spread. The patient made a slow but eventual recovery. The overall mortality of this condition is high, but early recognition of an abdominal source of sepsis with appropriate treatment can improve survival.

[Littre's hernia with appendix in its contents. Presentation of a case].

Littre's hernia is defined as any hernial sac which contains a Meckel's diverticulum. It has been reported in association with inguinal or femoral hernias principally and this hernia is rare but well described. A case is reported of a 44 years old man programmed for repair of a right inguinal hernia and we found incidentally that the sac contained a Meckel's diverticulum and the appendix. We reviewed the literature about this pathology and comment the management. It is concluded that the best management of Meckel's diverticulum is intestinal resection and the hernia, where the diverticulum was found, should be repaired.

The appendix in inflammatory bowel disease in children.

The morphologic characteristics of the colon in ulcerative colitis and Crohn's disease are well established, but specific appendiceal pathology is less clearly defined. In addition, the frequency of appendiceal involvement in children with inflammatory bowel disease has also not been delineated. We have determined the prevalence of appendiceal involvement in 41 children with inflammatory bowel disease (24 with Crohn's disease and 17 with ulcerative colitis) who required colonic resection and have defined the histopathologic characteristics of the appendix in these diseases. All appendices were abnormal. Specific changes of Crohn's disease or ulcerative colitis were observed respectively in 50% and 56% of the appendices in our patient population. Nonspecific changes only such as fibrous obliteration, serosal fibrosis and lymphoid and/or neuronal hyperplasia were noted in the remaining appendices. The severity of ileocolonic and appendiceal inflammation was similar in about two thirds of the patients with either type of inflammatory bowel disease.

[Anatomical variations of vermiform appendix].

Vermiform appendix (VA) is characterized by great variability of its location and morphology. Acute inflammatory changes are the most frequent cause of surgical abdominal interventions. Inflammation of atypically located VA may imitate inflammation of other organs, which leads to diagnostic errors. Based on anatomical and clinical data, especially those concerning location variability, different anatomical variations of VA are presented.

[Mucus secreting tumors of the appendix. Report of 22 cases].

The retrospective study presented in this article was realized on a series of 22 cases of mucus secreting tumor of the appendix compiled among 8373 appendicectomies. The clinical picture was dominated by an appendiceal syndrome (73%). The diagnosis was made pre or peroperatively in 10 cases and it was only with to the systematic anatomopathologic exam that 12 other cases were discovered. The histological study of the appendectomy piece showed a retention mucocele (12 cases), a mucosal hyperplasia (8 cases) and a cystadenoma (2 cases). For 5 patients, the diagnosis of peritoneal pseudomyxoma (4 cases) or extraperitoneal (1 case) was retained. All the patients underwent an appendicectomy, associated to an evacuation of the peritoneal gelatinous ascites for 5 patients among whom two underwent in more an omentectomie. Two cases of recurrence were recorded 5 months later.

[Granular cell tumor of the vermiform appendix. Case presentation with discussion of histogenesis].

Granular cell tumor is a rare lesion to the appendix. A case of that kind was recorded by the authors from a man, 32 years of age, who underwent surgery for appendicitis. Presence of a granular cell tumor was histologically, histochemically, and immunohistologically verified. Histogenesis of granular cell tumors is not well known, which prompted the authors to summarise some of their recent findings for discussion.

[Foreign bodies of appendix and caecum complicated with acute appendicitis].

Twelve patients with exogenous foreign bodies (small chicken and fish bones, portion of wire, nail, cherry stone, piece of glass) of appendix (8) or adjacent zone of caecum (4) were treated. Based on experience of treatment of these patients authors analyze pathogenesis of appendicitis associated with foreign bodies, and other aspects of this problem.

Terminal deoxynucleotidyl transferase-positive cells in spleen, appendix and branchial cleft cysts in pediatric patients.

We evaluated spleens (n = 26), appendices (n = 10) and branchial cleft cysts (n = 6) for TdT-positive cells in pediatric patients. In spleen, appendix and branchial cleft cysts the range of TdT-positivity was 0-13, 0-96 and 0-6 TdT+ cells/hpf, respectively. In spleens, scattered TdT+ cells were seen most frequently in periarteriolar lymphoid sheath regions.

Intussusception of vermiform appendix with microscopic melanosis coli: a case report.

Intussusception of the appendix is a rare occurrence. Due to the similarity of its symptoms with appendicitis, preoperative diagnosis of this condition is extremely difficult. In this report, we present appendiceal intussusception with histological melanosis coli that occurred in a patient on long-term anthranoid laxative use for chronic constipation. Melanosis coli in the appendiceal tissue, as an indicator of chronic laxative intake, may be a clue implying that the appendical exposure to hyperperistalsis for a long time in our case led to the intussusception. We conclude that colonoscopy may help in preoperative diagnosis of appendiceal intussusception in patients with suspicious appendicitis, particularly in those using laxative medication.

[Pinworm infestation of the appendix].

The Authors present 2 cases of enterobiasis of appendix observed on a total of 186 appendicectomies. Enterobius infestation is an uncommon cause of acute appendicitis. Preoperative diagnosis of pinworm infestation is almost impossible without clinical suspect. Parasites may produce symptoms which resemble acute appendicitis but parasitic infection rarely causes it. It is also important considered in the differential diagnosis cases that mimic Crohn's disease.

Infarcted epiploic appendage of the vermiform appendix masquerading as acute appendicitis.

Infrequent causes of right lower quadrant pain that mimic acute appendicitis include infarcted epiploic appendages. Although usually located in the colon, we report the very rare case of an infarcted epiploic appendage located directly on the serosal surface of the appendix itself. In a patient with right lower quadrant pain, the diagnosis of infarcted epiploic appendages is rarely made preoperatively and the incidence is rare. Definitive treatment is excision.

[Continent urinary diversion using the appendix as a catheterizable stoma].

Two patients with bladder cancer underwent construction of continent urinary reservoir using the in situ appendix as a catheterizable stoma after total cystectomy. Urodynamic study revealed that the reservoir had a large capacity of 500-800 ml and low pressure without the involuntary pressure spikes was maintained. X-rays of the reservoir showed no reflux. The patients achieved complete day and night-time continence.

Crohn's disease of the appendix.

Two patients with Crohn's disease confined to the appendix are described. The condition may present as acute appendicitis or appendiceal infiltrate. Therapy of either manifestation includes appendectomy. Concurrent Crohn's disease elsewhere in the gastrointestinal tract may be found in 25 per cent of the patients. A recurrence rate of 10 to 15 per cent in the remaining patients justifies a follow-up of some three years.

Complete appendicular inversion: the "inside-out" appendix. An unusual presentation of Crohn's disease. A case report and review of the literature.

Intussusception of the appendix into the caecum is an uncommon condition and the diagnosis is rarely made preoperatively. Specific anatomic requirements as well as pathological conditions that cause irritation or increased peristalsis should be present for this event to occur. A case is discussed in which the diagnosis was made preoperatively by barium enema and in which the lead point was a large inflammatory polyp due to Crohn's disease. It appeared in this case that inflation at the time of the barium enema resulted in reduction of the intussusception.

[Crohn's disease limited to the appendix. Apropos of a case].

A rare case of Crohn's disease limited to the appendix is reported in an 18 years old adolescent, hospitalised as having acute appendicitis. Appendectomy was performed. There were no postoperative complication and no recurrence after 3 years follow-up. Surgical indications are discussed and literature reviewed.

[Diverticula in the vermiform appendix].

A case of multiple appendiceal diverticula seen by barium enema is reported. Five diverticula were clearly demonstrated. The patient was asymptomatic. Most diverticula of the appendix have been found at laparotomy for complicated appendicitis. We believe that prophylactic appendectomy should be performed to prevent complications.
