A case of gastroduodenal intussusception secondary to transpyloric prolapse of a primary gastric carcinoma is reported. Both the condition itself and the leading tumor, gastric carcinoma, are extremely exceptional. A diagnosis of this rare entity was established pre-operatively by endoscopy that demonstrated spontaneous reduction of the intussusception. This may be the first documentation of spontaneous reduction of the gastroduodenal intussusception during endoscopy.

The management of rectal internal mucosal prolapse (RIMP) is not based on an accepted classification of the lesion which helps to choose the appropriate treatment. The aim of this prospective study was to report a new endoscopic grading of RIMP and to evaluate its clinical value. Thirty-two patients (7 men, 25 women; mean age 56 years, range 28-72) affected by symptomatic RIMP were prospectively classified as follows: RIMP was defined as first degree when detectable below the anorectal ring on straining, as second degree when it reached the dentate line, and as third degree when it reached the anal verge. Anal manometry was carried out in 26 patients, and anal ultrasound and defecography in 6 prior to surgery. A correlation was found between the occurrence and severity of symptoms and the degree of the prolapse as obstructed defecation, bleeding and fecal soiling affected mainly patients with third-degree RIMP. At manometry the maximal resting tone was 60+/-23 mm Hg and voluntary contraction 96+/-41 mm Hg (mean+/-SEM). At anal ultrasound the mean internal sphincter thickness was 2.1+/-0.2 mm, and external sphincter thickness was 7.0+/-0.8 mm. A significant rectocele and rectal intussusception (n = 2) and a nonrelaxing puborectalis muscle on straining (n = 2) were observed at defecography in cases with third-degree RIMP. The anorectal angle was 100+/-75 degrees at rest, 63+/-20 degrees on squeezing, and 115+/-9 degrees on straining. A conservative treatment with high-fiber diet and/or rubber band ligation was carried out in all cases of first and in most patients with second-degree RIMP (n = 26). Those who required surgery, i.e., stapled transanal excision of the prolapse (n = 6), had either severely symptomatic third-degree RIMP with solitary ulcer syndrome (n = 4) or second-degree RIMP (n = 2). A positive outcome was achieved in 71% of cases. The proposed classification evaluated by the present study may be of clinical value in managing rectal internal mucosal prolapse.

Endometriosis of the intestinal tract may mimic a number of diseases both clinically and pathologically. The authors evaluated 44 cases of intestinal endometriosis in which endometriosis was the primary pathologic diagnosis, and evaluated them for a variety of gross and histologic changes. Cases with preneoplastic or neoplastic changes were excluded specifically because they were the subject of a previous study. The patients ranged in age from 28 to 56 years (mean age, 44 years), and presenting complaints included abdominal pain (n = 15), an abdominal mass (n = 12), obstruction (n = 8), rectal bleeding (n = 2), infertility (n = 3), diarrhea (n = 2), and increasing urinary frequency (n = 1). The clinical differential diagnoses included diverticulitis, appendicitis, Crohn's disease, tubo-ovarian abscess, irritable bowel syndrome, carcinoma, and lymphoma. Forty-two patients underwent resection of the diseased intestine and two patients underwent endoscopic biopsies. In 13 patients there were predominantly mural masses, which were multiple in two patients (mean size, 2.6 cm). In addition, 11 cases had luminal stenosis or strictures, six had mucosal polyps, four had submucosal masses that ulcerated the mucosa (sometimes simulating carcinoma), three had serosal adhesions, one had deep fissures in the mucosa, and one was associated with appendiceal intussusception. Involvement of the lamina propria or submucosa was identified in 29 cases (66%) and, of these, 19 had features of chronic injury including architectural distortion (n = 19), dense lymphoplasmacytic infiltrates (n = 7), pyloric metaplasia of the ileum (n = 1), and fissures (n = 1). Three cases had features of mucosal prolapse (7%), ischemic changes were seen in four (9%), and segmental acute colitis and ulceration were seen in four and six cases (9% and 13%) respectively. In 14 patients, endometriosis formed irregular congeries of glands involving the intestinal surface epithelium, mimicking adenomatous changes. Mural changes included marked concentric smooth muscle hyperplasia and hypertrophy, neuronal hypertrophy and hyperplasia, and fibrosis of the muscularis propria with serositis. Follow-up of 20 patients (range, 1-30 years; mean, 7.8 years) revealed that only two patients had recurrent symptoms. None of the patients developed inflammatory bowel disease. Endometriosis can involve the intestinal tract extensively, causing a variety of clinical symptoms, and can result in a spectrum of mucosal alterations. Because the endometriotic foci may be inaccessible to endoscopic biopsy or may not be sampled because of their focality, clinicians and pathologists should be aware of the potential of this condition to mimic other intestinal diseases.

With the exception of angiodysplasia, vascular abnormalities of the intestines are unusual. We describe a florid benign vascular proliferation of the colon in five adult patients, three of whom presented with idiopathic intussusception. In all cases, the proliferation was sufficiently exuberant to raise the possibility of angiosarcoma as a diagnostic consideration. The group included 2 males and 3 females with a median age of 43 years. Two patients were HIV positive. Four patients presented with a colonic mass; other symptoms at presentation included abdominal pain, diarrhea, bleeding, and bowel obstruction. In all cases, a florid lobular proliferation of small vascular channels lined by plump endothelial cells extended from the submucosa through the entire thickness of the bowel wall. The endothelial cells showed minimal nuclear atypia, and mitotic figures were infrequent. The overlying mucosa showed ulceration with ischemic-type changes, and had features of mucosal prolapse. A possible underlying arteriovenous malformation was identified in two cases. All patients were alive and well at last follow-up (interval, 6 months to 5 years). The presence of intussusception or mucosal prolapse in all of the cases suggests repeated mechanical forces applied to the bowel wall as a possible etiologic factor. The role of HIV infection in the pathogenesis of these lesions remains to be determined.

The Longo technique using a circular stapler has changed haemorrhoid therapy. Thanks to the advent of this technique for treating haemorrhoids without excision, we can now successfully eliminate the mechanism responsible for their pathogenesis. The aims of circumferential stapled anoplasty are to correct the anodermal prolapse and restore the haemorrhoidal cushions to their anatomical position. Furthermore, with a few variants the technique can be utilised for other proctological problems, such as obstructed defecation in rectocele and incomplete internal prolapse (or rectal intussusception). The authors report on their experience in a consecutive series of 122 cases undergoing circular stapled anoplasty for haemorrhoids, associated in 10 cases with rectocele or rectal intussuscep-tion, analysing early and late complications after an accurate follow-up. The procedure can be performed with local or spinal anaesthesia. The operation lasted on average 19 minutes. There were few complications: early bleeding (4.9%), late bleeding (0.8%), mild stricture (2.5%) and thrombosis of external piles (8.2%). This new surgical technique is effective and rapid, causes only minimal postoperative pain and could be proposed as an alternative to traditional surgery also in the day surgery setting.

The initial treatment for patients with colitis cystica profunda is aimed at re-education of bowel habits to avoid straining. Patients are instructed to spend the minimum time on the commode. A high-fiber diet with bulk laxatives is recommended. If fiber does not work, polyethylene glycol solutions and surface-active stool softeners such as docusate sodium are tried. Conservative therapy resolves most symptoms. Biofeedback is offered to patients who fail dietary therapy. For patients with associated rectal prolapse, an operation designed to correct the intussusception is considered. For full-thickness prolapse (procidentia) a mucosal resection (Delorme) or perineal proctectomy (Altemeier) is recommended. Surgical treatment of internal (occult) prolapse is problematic. If attempted, a resection and suture rectopexy has the most support. In the absence of procidentia, transanal excision may be used in selected patients. If other measures fail, a mucosal sleeve resection with coloanal pull-through or a diverting colostomy may be considered.

Selection of an appropriate approach to treat full thickness rectal prolapse remains problematic and controversial. We propose that rectal prolapse may be classified as 'low type' (true rectal prolapse) or 'high type' (intussusception of the sigmoid with a fixed lower rectum). This assessment can be made via a simple clinical test of digital rectal assessment of lower rectal fixity ('the hook test') based on anatomic changes in rectal prolapse to guide the selection process. In cases with the low-type prolapse, a perineal approach is appropriate (either Delorme's procedure, or rectosigmoidectomy with or without pelvic floor repair). For the high type, an abdominal rectopexy with or without high anterior resection is needed. Retrospective analysis of our cases treated over the last 6 years showed a recurrence rate of 6% in perineal procedures and 0% in abdominal rectopexy combined with resection to date. We believe that employing our simple test and classification can contribute to better patient selection for either approach, minimize anaesthetic and surgical risks and also result in lower recurrence rates.

Obstructive defecation is observed in approximately half of all patients with functional constipation. Functional constipation has been related to alterations in intestinal motility (slow transit constipation) and to pelvic floor disorders leading to obstructive defecation associated with anatomical alterations of the pelvic floor (rectocele, posterior perineal hernia, enterocele and sigmoidocele, internal rectal intussusception, occult mucosal prolapse, solitary rectal ulcer and descending perineum syndrome), or obstructive defecation without anatomical alterations (pelvic floor dyssynergy or anismus). The diagnostic methods used (history and physical examination, colonic transit time, balloon expulsion test, proctography, anorectal manometry and electromyography) are reviewed. Conservative medical treatment and the indications for surgical treatment and its results are also discussed.

Cystic fibrosis is a common inherited fatal disease. As the life expectancy of affected individuals continues to increase with advances in disease management, this disease is no longer limited to the pediatric population. Currently, 40% of patients with cystic fibrosis are adults. In addition, patients may not present until adulthood and frequently have extrapulmonary symptoms. Abdominal manifestations are common and affect multiple organ systems. Hepatobiliary manifestations include fatty infiltration of the liver, gallbladder abnormalities, bile duct abnormalities, focal biliary fibrosis, and multinodular cirrhosis. Manifestations in the pancreas include acute pancreatitis, fatty replacement, calcifications, cysts, duct abnormalities, and carcinoma. Gastrointestinal manifestations include gastroesophageal reflux, peptic ulceration of the gastric and duodenal mucosa, distal intestinal obstruction syndrome, intussusception, appendicitis, fibrosing colonopathy, pneumatosis intestinalis, rectal mucosal prolapse, malignancies, and pseudomembranous colitis. Renal manifestations include nephrolithiasis, as well as secondary renal complications such as interstitial nephritis due to antibiotic therapy and amyloidosis. Awareness of these manifestations is important to successfully guide management of cystic fibrosis in adult patients.
