[Miles operation in rectal carcinoma: history and current status].

The Authors confirm how the advent of mechanical suture has directed the management of rectal carcinoma to an increasingly conservative attitude. In reporting their experience--which consists of about twenty years (222 patients) they specify how not only an increased incidence of recurrence has not appeared, but they have also observed a reduction of theirs (-5.2%). They then attempt to outline basic moments which have characterized the history of rectal carcinoma surgery and they state how today, 80 years since it was conceived, Miles' intervention maintains its validity, even if with more restrictive indications.

[Reflections on mesenteric infarct].

The authors relate their statistic about mesenteric infarction in the last five years and they get out the starting point in order to check the characteristics of a disease, which is today distinguished by an infaust prognosis. After few mentions about etiopathology and pathologic anatomy they keep their attention on clinic manifestations of disease and on diagnostic research. After dealing with medical and surgical therapy they declare how more refined diagnostic technique could help early diagnosis and consequently decrease morbidity and morbidity, which are completely unacceptable.

[Intrahepatic biliary lithiasis: experience in 20 years].

In confirming that intrahepatic gallstones don't represent a frequent disease in western countries, Authors specify how this incidence is going to grow up slowly, but in a progressive way. In reporting their experience since 1980 to nowadays they point out how different diagnostic procedures and therapy way of acting were in the first and in the second deca. After having explained actual therapeutic direction that is described in literature, they finish by stating how this is often conditioned by complex anatomicopathological picture and by seriousness of hepatic damage that often comes with intrahepatic lithiasis.

[Anastomotic dehiscence in colorectal surgery].

Anastomotic leakage represents the most dangerous complication in digestive surgery and, particularly, in colorectal one. Indeed a careful evaluation and modification of all possible risk factors and a correct procedure aren't often enough to overcome a potential postoperative leakage or at least material filtration. The Authors review their series to analyse the role of all possible general and local risk factors and to verify what conditions can suggest an two or three stages operation.

[GIST of the jejuno-ileal tract].

Jejunum-ileum stromal tumors give diagnostic and therapeutical problems, especially with regard to histopathological identification and biological behavior. These tumors are very rare in all case report. After gastric stromal tumors these ones are the most frequent of all alimentary tract. They are often incidentally found; because of their potential transformation, they have to be treated by respecting oncologic eradication standards and observing prognostic criteria based on a correct histopathological evaluation (neoplasm localization and dimension, its structure, presence of cytological atypisms, mitotic index, ploidia, surgical resection). Then there has to be a good follow-up program.

[Our experience with early gastric cancer].

Authors assert that, in Early gastric cancer diagnosis, anatomicomedical characteristics expressed on the basis of canons formulated by Endoscopy Japanese Society and by Lauren's unexipered classification are of particular interest. After having referred on characteristics observed on a group of patients, in the light of data given from medical Literature, they try to extrapolate aetiopathogenetic factors. These, together with anatomicopathological characteristics of the lesion, are the premises for a wise radical therapeutic choice.

[Anatomo-clinical considerations on early gastric cancer].

After having asserted the still rising interest for an as early as possible diagnosis of gastric cancer, authors refer on a group of patients who are carriers of Early gastric cancer. After having touched upon localization and histological characteristics of neoplasms, linger on the rules that leaded their therapeutic choice and they report the results of a follow-up dragged ten years long. They terminate affirming only a timeliness diagnosis can consent a really decisive therapeutic approach.

[Clinical considerations on spontaneous pneumothorax].

The authors, after confirming the social interest of spontaneous pneumothorax, report the results of their experience taking hint from it for some clinical considerations. They mention different therapies suggested for the treatment of this disease; particularly they dwell upon aspiration techniques considered today the treatment of choice in most cases. They conclude affirming that this technique improves results, diminishes risks and complications, and considerably reduces hospitalization.

[Mechanical intestinal occlusion due to phytobezoars].

The Authors reporting two cases with ileus by phytobezoar in distal jejunum and ileum, respectively, and discuss the pathophysiologic mechanism responsible for the formation of bezoars. They expose the etiological and clinical factors of this uncommon cause of small bowel obstruction and also discuss the surgical technique that consists in the removal of the phytobezoar through enterotomy.

[A rare salivary gland neoplasm: cystadenolymphoma].

The authors, after having examined three recent cases, explain some basic concepts about diagnostics and therapy in cystadenolymphoma of salivary glands. As a matter of fact this neoplasia, in spite of its low frequency, is very important because of its still controversial etiopathology and recent tendency in increasing its incidence in females. Today the diagnostic protocol, undertaken after clinical examination, which is necessary, consists of ultrasonography or computerized tomography. But only postoperative histological examination gives a sure diagnosis and can point out main histomorphological characteristics of tumour. Therapeutic approach can be limited to conservative treatment, which is able to respect the parotid gland, its vascularization and innervation.

[Diagnosis and treatment of Crohn's disease].

The Authors state their ideas and report their experience about diagnosis and treatment of Crohn's disease. After having treated risk and etiological factors, they discuss typical anatomo-pathological lesions. Then they explain clinical diagnostic and surgical choices extensively: they prefer laparotomic approach. The Author's conclude that timely diagnosis spare heavy complications.

[Ileum-colon junction benign obstructions].

The Authors discuss on anatomical and functional characteristics of ileum-colon junction, physiological narrowing in alimentary tract and often involved in benign obstruction. They report their series and analyze all inflammatory or not inflammatory diseases potentially involved, by describing them shortly and giving some information about their clinical features and imaging. The treatment of this obstruction will be done as soon as possible, before wall lesions force to make a larger resection.

[Acute pancreatitis: our experience in the light of natural history].

The Authors enumerate main steps of acute pancreatitis natural history. Then they discuss their last five years case-report. After having stated that clinical presentation depends on anatomo-pathological conditions, they consider aetiological causes and morphopathogenetic moments involved in the onset and development of this disease. They conclude stating how only proper diagnosis and treatment can prevent its potential evolution in multiorgan failure.

[Etiopathogenic hypothesis on carcinoma of the gallbladder: our study].

The authors are interested in determining causes of gallbladder cancer (GBC). By this intention, they theorize a correlation between genetic modifications (which are responsible of malignant transformation of biliary epithelium) and some intestinal infections. From 1999 to 2004 they observed 15 GBC and all 15 gallbladder have been analyzed histologically and from microbiological aspect; by these means from 1999 till 2004 they have studied also 30 persons with colelithiasis. The authors noticed that bile of both groups contained, in three cases in the first and in 8 cases in the second, a germ named Escherichia Coli which normally lives in intestine, while in 10 operated gallbladders of the first group and 12 of the second there was a positive for k-ras. They are studying to confirm their theories.

[Treatment of skin neoplasms with polidocanol infiltrations. Our experience].

The authors try to explain the importance of day surgery today. They report their 5 years experience in treatment of face and neck skin neoplasms by injections of a sclerosant product as hydropolyethoxydodecan, in case of a difficult good esthetic result with surgery or other therapies because of patients general conditions, such as diabetic ones, or because of their viral nature. Then they affirm to have treated 350 benign and malign tumors with this method. All subjects presented a complete resolution of disease in few weeks and none between them controlled has actually complications or recruitment of neoplasm. They conclude by saying that this result is probably due to local ischemic reaction caused by the substance used.

[Colorectal carcinoma in young patients: review of 10-year experience].

The authors, in reaffirming the high incidence of the mucin-producing type of colo-rectal adenocarcinoma in young patients, underline the considerable aggressiveness of this tumor. After a brief note on the etiopathogenetic hypothesis which could explain such behavior, the factors usually contributing to a worsening of the prognosis are reviewed. Thus, the Authors report their series and conclude affirming as indispensable to arrive to an early diagnosis.

[Minimal breast carcinoma (the authors' experience)].

The authors relate their experience about twenty-one cases of impalpable lesions of the breast come to their observation during the years 84-88. After expanding therapeutical tactics carried out by them, the promoters infer asserting that a wide diffusion of screening programmes allowed a more verifications of the minute lesions of the breast, addressing the surgeon towards operations more and more conservatives.
