Meckel’s diverticulum is a common anomaly of the gastrointestinal tract. The most common complications of Meckel’s diverticulum are inflammation, bleeding and obstruction. We present a 12-year-old boy with bowel obstruction due to phytobezoar in a Meckel’s diverticulum. We describe diagnostic difficulties and our surgery approach comparing it to the literature.

Acute abdomen is a continuous clinical challenge in pediatric age. The aim of our study is to describe two pediatric rare cases: the first case is a small bowel volvolus related to Meckel’s diverticulum confused with an intestinal intussusception; the second an internal herniation related to epiploic appendagitis with intestinal obstruction mimic acute appendicitis in two years old children. We review the current literature. Keywords: Pediatric, Caecal appendagitis, appendices epiploicae, acute abdomen, Meckel’s Diverticulum, Small Bowel Obstruction, Volvolus, Internal hernia, Appendicitis.

The aim of the study was to assess the accuracy of multidetector CT (MDCT) with MPR reformation in the evaluation of large bowel obstruction. Thirty-one patients were evaluated retrospectively in a blinded fashion by two radiologists. All patients underwent MDCT with multiplanar reformation (MPR). The two radiologists interpreted independently the axial images and then the reconstructions. Each patient received a score from 1 (absent occlusion) to 5 (confirmed occlusion). The results were compared with surgical findings. Both axial and MPR images showed a very high accuracy in the diagnosis of bowel obstruction with a significant advantage of MPRs over native images and without any difference between the two radiologists. MDCT is an accurate technique in the evaluation of large bowel obstruction and use of MPRs facilitates the interpretation of imaging findings.

We report a case of a 52-year-old woman with hemorrhoids submitted to Procedure for Prolapse and Hemorrhoids (PPH), i.e. stapled hemorrhoidopexy, using a modified Longo's technique (double purse string) to treat an associated rectocele and rectal prolapse; the STARR technique (Stapled Trans Anal Rectal Resection) was not yet codified. The post-operative course was uneventful and the patient is discharged in II p.o. day. In fifth post-operative day the patient came back with an unusual rectal stenosis due to the superior purse string. The stricture was easily resolved by 'opening' the purse string with a transanal approach in outpatient setting.

A retrospective study on 18 patients with cecal volvulus surgically treated was made. Demographics and clinical data, as well as treatment were determined from clinical reports. The operative procedures employed were cecostomy (56%), cecopexy (22%) and right colectomy (22%). The length of follow up averaged 63 months and there was one recurrence. The Authors suggest that cecostomy should be employed in patients with viable bowel, and resection should be limited to cases with gangrene.

A peculiar case of intestinal occlusion caused by a renal stone in a patient with nephroduodenal fistula due to previous xanthogranulomatous pyelonephritis is reported. Only few cases of nephroduodenal fistula are described in the literature, generally as a single case report or in small series. A nephroduodenal fistula as a result of chronic renal inflammatory disease such as xanthogranulomatous pyelonephritis, is usually associated with renal stones, recurrent urinary tract infections or endocrine disorders. Finally, renal stone as a cause of ileus is an event rarely described in the literature. In the case described, a correct preoperative diagnosis was possible with computerized tomography. During the operation a big renal stone was found and removed from the small bowel, but a limited resection was necessary because of the vascular impairment of the tract. At 8-month follow-up from operation, the patient was in good health, and no symptoms of renal or intestinal diseases were found.

The Authors report a case of ovarian endometriosis causing an "Ab extrinseco" sigmoid stenosis. The histogenesis as well as different possibilities of treatment, i.e. medical and surgical, are discussed.

Colorectal cancer is the second most common malignancy of the adult population in the United States. It is exceeded only by lung cancer among males and breast cancer among females. Malignancies of the colon and rectum are responsible for approximately 12 per cent of all adult cancer deaths. These tumors appear as surgical urgency by intestinal obstruction for 15-20 per cent and by perforation for 3-8 per cent of all cases. It often occurs in elderly patients; in fact, urgent surgical operations are especially performed in patients older than seventy. The mortality rate for urgent surgical operation in elderly patients is about 32-54 per cent. This high mortality is even due to concurrent pathologies and particular locoregional and/or general alterations induced by tumor. The authors studied all patients older than 75 years affected by colorectal cancer and treated by choice or by urgency at Dept. of Surgery of the University of Perugia from January 1987 to February 1993 to individualize some clinical, anatomo-pathological and therapeutical significant characteristics about colorectal cancer in geriatric age.
