The usefulness of lateral internal sphincterotomy combined with hemorrhoidectomy in the treatment of hemorrhoids: a randomized prospective study
No full textThe aim of this prospective randomized study was to investigate anorectal manometric findings in hemorrhoid patients and to evaluate the clinical benefits and physiological consequences of additioning a lateral internal sphincterotomy (LIS) to haemorrhoidectomy. Anorectal manometry was preoperatively performed in forty-eight consecutive patients with prolapsed piles; resting and squeeze pressures, sphincter length and rectoanal inhibitory reflex were recorded. Ten healthy volunteers served as controls. Six patients were excluded because no raised and pressures were found. Forty-two patients were randomised: Group 1 (n = 22) patients underwent haemorrhoidectomy plus LIS; Group 2 (n = 20) patients underwent haemorrhoidectomy alone. Postoperative course was carefully evaluated; all patients were questioned about continence and anorectal manometry was repeated twice. Sphincter anomalies were found in 87.5% of patients. Haemorrhoidectomy alone did not affect anal pressures, which returned into the normal ranges after sphincterotomy. Postoperative course was better in LIS group. Anal stricture was seen in four patients without sphincterotomy; no patients with LIS experienced and incontinence. This study shows that high and pressures are very frequent in hemorrhoid patients; they are not due to hypertensive and cushions and might have a pathogenetic role. Anorectal manometry is very useful to identify patients with raised anal pressures; in these cases additioning a lateral internal sphincterotomy to haemorrhoidectomy seems justified; it significantly improves postoperative course and can be safely performed
Hereditary colorectal cancer: Analysis of three high risk families
No full textHereditary colorectal cancer is a clearly identified entity today; it is transmitted as a dominant autosomal heritage, and represents about 25% of large bowel malignancies. The poor prognosis of this tumor, one of the most frequent in Western Countries, despite the improvements in therapeutic field, is due to a delated diagnosis that affects an advanced stage of disease in which the results of treatment are significantly worse, whereas cumulative 5-year survival rate is 35% vs 95% in early stage tumors. Existence of an inherited cancer, even in the absence, at present, of specific biomarkers, allows to identify a high risk population in which early diagnosis of colorectal cancer is possible, on the basis of anamnestic and clinical features. Only in this way, with the extension of the results to general population, prognosis of colorectal cancer will be improved
Gallstone ileus: Literature review and report of a case treated with minilapa-rotomy
No full textMaterial and methods: A gallstone ileus report, diagnosed by integrated radiological approach, treated by minilaparotomy plus enterolithotomy and followed up for two years. Results: Traditional radiologic findings, idtrasonography and computed tomography showed both the stone in the bowel lumen and the cholecystoduodenal fistula with air in the biliary tract. The enterolithotomy alone worked out the obstruction and no complication was observed. Discussion: Integrated radiologic examinations are indicated in defining nature, site and seriousness of gallstone ileus. In most cases surgical treatment is mandatory to work out both the bowel occlusion and bilioenteric illness even though it is often wiser to perform an operation of enterolithotomy alone owing to the general and local conditions of the patient. After this surgical approach, bilioenteric fistula disappears in most cases with no residual lithiasis; in the cases in which fistula and/or lithiasis persist, a decisive surgical operation can be performed in a second step. © 2000 GEM s.r.l
Ectopic thyroid: report of a case
No full textThe development of thyroid tissue can occur in any moment of the migration of the thyroid along the thyroglossal duct from the tongue, resulting in lingual (at tongue base), sublingual (below the tongue), prelaryngeal (in front of the larynx), and substernal (in the mediastinum) ectopy. Thyroglossal duct cyst is the most common type of clinical abnormality related to thyroid ectopy. Surgical removal of such ectopic tissue is justified since some Authors describe thyroid cancer arising from aberrant thyroid tissue. The Authors report a case of thyroid ectopy in a patient who underwent 20 years before a left thyroid resection with isthmectomy; during the operation the surgeon described a hypertrophic pyramidal lobe which was left in situ and the patients did not receive any hormone suppressing therapy

The finding of vascular and urinary anomalies in the harvested kidney for transplantation . Transplantation Proceedings 2007, 39,1797-1799
No full textRenal anatomic anomalies are frequently observed during kidney transplantation and may produce postsurgical complications. However, the presence of these anomalies does not necessarily imply the impossibility of using the kidney for a transplant, especially because of improved surgical techniques. Our experience in transplantation procedures showed that even if kidneys present the above-mentioned anomalies they can still be considered appropriate for transplantation when we perform a correct harvesting/back-table transplant surgery. So vascular and urinary anomalies have to be considered always an incentive to research new surgical solutions and to perform a careful surgical technique
Can only histological evaluation determine the allocation of ECD kidneys?
Full text linkThere is a recent debate on the "transplantability" of ECD (Expanded Criteria Donors) kidneys and the selection criteria used to allocate them to single or double transplantation. Remuzzi et al. have defined a protocol incorporating pre-transplant donor biopsy to guide the use of older donor organs. They allocated organs as single or double transplants on the basis of histological findings. We aim to show the pros and cons of the only histological evaluation in the allocation of ECD kidneys, to compare the different experiences in United States and Europe and thus to discuss whether this tool should be used alone or included in a comprehensive clinical and histopathological evaluation.
In the United States many Authors stated that the biopsy actually increases the percentage of kidney discarded and they raised questions about the importance of the biopsy in evaluating ECD kidneys for transplantation. On the other hand, the experiences of the majority of european transplant centers showed that allocating kidneys as single or dual transplant based on biopsy findings may achieve good graft and patient outcomes. Moreover, the experience of some centers as ours showed that kidneys allocated as DKT (Dual Kidney Transplant) on the basis of Remuzzi's score could have been suitable for single transplantation suggesting the need of an adjustment of the Remuzzi Score System. Many Authors, who are in favor of histological evaluation, actually believe that a comprehensive clinical and histopathological assessment before transplantation remains necessary. We lack precise national- or international-based selection criteria to guide clinicians. An adjustment of the Remuzzi Score System could be taken into consideration such as narrowing the indication for DKT from those ECD kidneys with higher scores and including the histological evaluation in a multifactor score
