[Perineal rupture and anorectal incontinence with traumatic sacroiliac dislocation. Treatment and functional results].

A case of traumatic sacro-iliac disruption with severe perineal rupture and ano-rectal incontinence by total unilateral laceration of the levator ani muscle is reported. The use of parenteral hyperalimentation as a "medical colostomy" has been successfully applied maintaining the patient's nutritional status while healing of the wound occurred. This gives the surgeon an option for the management of such a severe sphincter's laceration: without resorting to preliminary colostomy. The general management of patients with perineal and rectal trauma is reviewed. The prerequisite of bone fracture consolidation prior soft tissue repair is emphasized. Progressive recovery of ano-rectal continence is demonstrated by repeated ano-rectal manometry.

The clinical [corrected] background of familial adenomatous polyposis. History, epidemiology, diagnosis and treatment.

Familial adenomatous polyposis (FAP) is a dominantly inherited genetic disorder predisposing to colon cancer through the early development of multiple adenomatous polyps in the large bowel. FAP is not restricted to the colon and rectum, but is a more complex disease which can potentially affect almost any organ not only with benign tumours but also with life threatening carcinomas. Desmoid tumours and gastroduodenal polyps and cancer are the two more worrying extracolonic manifestations of FAP. Recent advances in FAP knowledge, such as the report of congenital hypertrophy of the retinal pigment epithelium (CHRPE) or the APC gene identification, are very useful for screening and long-term follow-up of the patients through regional or national registries. Nutritional and pharmacological intervention trials are under way to assess potential new medical treatments of FAP. Surgery is still the only effective treatment for colorectal cancer prevention in FAP. The choice of a surgical procedure is controversial, but the introduction of total proctocolectomy with ileal pouch-anal anastomosis can be considered as a major advance in surgical treatment of FAP during the last decade.

Intraductal papillary-mucinous tumours of the pancreas. Clinical and radiological aspects.

Intraductal papillary-mucinous tumours are rare epithelial tumours with all intermediate types occurring from papillary to mucin-hypersecreting forms. They affects generally old men and recurring pancreatitis is the main clinical feature. Endoscopic Retrograde Pancreatography is the best diagnostic method, showing large dilatation of the ducts and filling defects due to mucin's plugs or papillary tumour. IPMT are slow-growing and have low malignant potential; as to far, surgical resection is considered mandatory, however, better distinction between benign and malignant evolution will probably select cases in which conservative follow-up may be proposed.

Mesenterico-left intrahepatic portal vein shunt: original technique to treat symptomatic extrahepatic portal hypertension.

UNLABELLED: MESENTERICO-LEFT INTRAHEPATIC PORTAL VEIN SHUNT: Original technique to treat symptomatic extrahepatic portal hypertension. OBJECTIVE: Revascularization of the intrahepatic portal system as decompressive surgery for chronic extrahepatic portal hypertension. SUMMARY BACKGROUND DATA: In patients with extrahepatic portal hypertension (portal trunk thrombosis in presence of a normal liver), shunt surgery is indicated when patient is bleeding from varices at a site not accessible for the endoscopist. Although surgical portal decompression is an efficient procedure, there is a risk of depriving the liver from the splanchnic venous flow and a risk of developing porto-systemic shunt related side effects. METHOD: A shunt was created between the superior mesenteric vein and the umbilical portion of the left portal vein. This technique allows to bypass the thrombosed portion of the portal vein but avoiding dissection of the cavernoma in the liver hilum and related risk of intraoperative hemorrhage. RESULTS: The procedure was successfully performed in one adult patient considered unshuntable in view of classic surgical procedures and in whom sclerotherapy was unsuccessful. This operation achieved an effective decompression of the splanchnic venous system. CONCLUSION: Rerouting the venous splanchnic flow through the liver was possible. It had the major physiological advantage of restoring the normal hepatic vascularization. It also avoided putting the patient at risk of developing porto-systemic shunt related side effects. This option should be considered when shunt procedures are indicated in patients with extrahepatic portal hypertension.
