Serum levels of interleukin 1beta, interleukin 8 and tumour necrosis factor alpha as markers of gastric cancer.

Despite the efforts made, a serum marker reliable for the screening and follow-up of patients with gastric cancer has not yet been identified. The aim of this preliminary study was to test the role of pro-inflammatory cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha in patients with gastric cancer and in control groups. The statistical analysis of cytokines serum levels in the group with gastric cancer versus control groups has shown considerable differences (p < 0.001) in their mean rates. The results indicate that the cytokines interleukin 1beta, interleukin 8 and tumour necrosis factor alpha might perhaps act as diagnostic markers in patients with gastric cancer. Therefore, it is hypothesized that after more extended trials, their use in the screening and prognostic assessment of these patients could be a possibility.

[The surgical treatment of Zenker's diverticula by stapler diverticulectomy and myotomy under local anesthesia].

From 1990 to 1997, 12 patients with Zenker's diverticulum underwent TA 30-stapler diverticulectomy and cricopharyngeal myotomy. All patients were operated on under local anaesthesia. No death was observed. In two cases subcutaneous infection was drained with recovery. No post-operative fistulas were observed with radiologic control. At 6 months follow-up all patients were well. Advantages of both stapler diverticulectomy and local anesthesia are outlined.

[Authors' experience with the role of preoperative ultrasonography in the study of benign lesions of the gallbladder].

The benign parietal lesions of the gallbladder are diseases that, as known, found their pathogenetic moment on hyperplasia of constituent tissues of the gallbladder wall and comprises the controversial chapter of "cholecystosis". The Authors, to contribute to their better clinical and pathogenetic staging, report their experience on 25 cases. They debate on the usefulness of ultrasonography, surely a diagnostic progress for these formations, which are small structures more or less echogenic and that they develop in the gallbladder; the echographic imaging, for its sharpening, has substituted the cholecystographic procedure. The aim of present study is to analyse the results obtained by using echography as diagnostic preoperative procedure of "cholecystosis". The ultrasonography supplies the surgeon an indication to prophylactic surgical treatment as single, effective procedure in preventing the gallbladder carcinoma.

Diagnostic possibilities and clinical indications of policlonal labeled Ig in the bowel inflammatory disease.

BACKGROUND/AIMS: Ulcerative colitis (UC) and Crohn's disease (CD) represent the more common forms of idiopathic inflammatory bowel disease. They have a peculiar course, which is characterized by exacerbation and submissions, and a symptomatology that changes in relation to severity and extension of the lesions. The aim of this study is to establish the diagnostic usefulness of 99m Tc human policlonal immunoglobulin (HIG) imaging in patients with inflammatory bowel disease (IBD). METHODOLOGY: During the period between September 1995 and September 1997 we submitted a group of 32 patients affected by UC (n = 22) and CD (n = 10), to Human Immunoglobulin labeled with Technetium 99m (99m Tc-HIG) scintigraphy. The diagnosis of IBD was obtained in all cases by endoscopy with biopsy. RESULTS: Scintigraphic examination with labeled HIG showed an abnormal intestinal fixation (ileal or colic) of the marked immunoglobulins in 17 patients (77.2%) affected by UC and in 8 patients (80%) affected by CD. In 5 (22.7%) and 2 (20%) patients, respectively, the scintigraphic examination revealed a normal distribution of the immunoglobulins without appreciable focal accumulation. Among the patients with a negative scintigraphic examination, only one presented an endoscopic and histologic report that documented UC in an active stage. The histologic and endoscopic findings observed in all cases of CD were similar to that of HIG scintigraphy in 7 of the 8 scintigraphic-positive cases and in 1 of the 2 scintigraphic-negative patients. CONCLUSIONS: The authors, on the basis of their results, suggest that this diagnostic strategy may have a significant role in the diagnostic protocol and in the follow-up of chronic inflammatory bowel disease.

[A case of strangulated trans-omentum hernia].

After a review of the Literature, the Authors report a case of intestinal obstruction caused by trans-omentum hernia. This unusual disease is due to a defect of the greater omentum with herniation and secondary strangulation of small bowel. The clinical presentation was that of an intestinal obstruction with rare possibility of preoperative diagnosis. Therefore, a correct knowledge of this pathology and immediate surgery are necessary for the prognosis.

[Diaphragm rupture caused by closed trauma. A more and more frequent condition].

The Authors report a case of rupture of the diaphragm in blunt trauma of the abdomen, to examine the more significant features of this condition whose incidence proves to be increasing, after a review of the literature data, parallel to the increase of accidents on the road and at work. They examine the most important pathogenic problems and these related to the mechanism leading to diaphragmatic lesion and they highlight the deeper pathophysiological changes suffered from the patient with such a condition. They draw attention to what they consider to be the most important aspect, and therefore the diagnosis. In fact, in accordance with the various series of cases reported in the literature, it is crucial in the diagnostic problem is when the possible cause of the rupture is suspected and necessary diagnostic cascade (Rx, echotomography, TC) is activated so to highlight the lesion. Therefore a quick diagnostic fitting is necessary for the survival of the acute patient with hernia of the thorax cavity, as well as quick surgical correction of the lesion that, as in the case described, serves to achieve the best possible anatomic-functional results.

[Clinical and etiopathogenetic evaluation of a rare cause of spontaneous pneumoperitoneum and volvulus of the ileum: pneumatosis cystoides intestinalis. Report of a case].

A case of pneumatosis cystoides intestinalis with pneumoperitoneum and volvulus complications is reported. After careful examination of the literature, etiopathogenic, pathophysiological and clinical features of the disease are analyzed by the Authors, also in the light of recent findings. Major diagnostic and therapeutic implications are discussed regarding possible complications requiring a different therapeutic approach. PCI, a lesion which can be benign, primary or secondary in many conditions, may be characterized by the presence of spontaneous pneumoperitoneum which only requires a careful, but not aggressive therapy, unlike other complications such as volvulus or intestinal occlusion which, instead, require timely surgical action. The Authors describing the therapy adopted, highlight the positive role of the enteral nutrition (NE) and oxygen therapy in the clinical course of the disease.

[The Allgrove syndrome].

Allgrove syndrome, rare autosomal recessive pathology, characterized by adrenocortical insufficiency, achalasia and alacrimia, rises usually in pediatric age, while its observation in adults is very rare. A clinical case appeared in an adult, observed by the Authors, is the reason to evaluate the etiopathogenetic mechanisms of this syndrome, with particular attention about potential role of genetic abnormalities and about others factors, again not well known.

[Idiopathic varicocele. Diagnosis and follow-up with CW-Doppler and Echo-Color-Doppler: our experience].

The Authors outline their experience on routine use of Doppler velocimetry in pre- and post-operation studies on patients affected with idiopathic varicocele. This instrumental study, characterized by non-invasive techniques and repeatability, if correctly carried out, allows both accurate identification of anatomical alterations which are at the bottom of varicocele and correct indications for surgical treatment. Moreover the Authors confirm the importance of spermatic veins ligature following the Ivanissevich method in the treatment of male infertility.

[Myogenic stromal tumors of the stomach: personal experience].

Myogenic gastric tumours are a rare pathology and present difficulties in terms of nosographic classification, which in most cases can be overcome thanks to improvements in imaging and immunohistochemical techniques. Over the period 1995-1999 we observed 5 patients with aspecific dyspeptic symptoms and occasional epigastric pain, suffering from non-epithelial gastric tumours, associated, in one case, with a carcinoma of the stomach. Histological examination of endoscopic biopsies was inconclusive for a definite histopathological diagnosis, while intraoperative biopsies showed the myogenic origin and the absence of morphostructural abnormalities. In the light of these data, we performed three wedge resections, one distal gastric resection and, in the patient with advanced gastric cancer, a D3 total gastrectomy. Histological examination, immunohistochemistry and cytofluorometry enabled us to diagnose stromal tumours with a low risk of malignancy in all cases. At follow-up after 9-54 months all patients are still alive and free of disease. Though the preoperative diagnosis of stromal tumours is possible with endosonography and CT, only histology, immunohistochemistry and cytofluorometry enable us to define the condition nosographically and establish a prognosis with sufficient accuracy to allow correct surgical treatment. A prolonged follow-up is always necessary to identify eventual relapses and/or metastases, which are particularly frequent in the borderline group or in cases with a high risk of malignancy.

[Combined diagnosis in breast carcinoma: preoperative role of mammoscintigraphy with Tc99m-sestamibi. Our Experience].

The Authors, taking recent literature on tumoral pathology breast studies in to consideration, studied a group of patients with a node or a suspect adenous zone by clinical and instrumental examination with mammoscintigraphy. 22 patients were selected by clinical examination, mammography and ultrasonography. A mammoscintigraphy (Tc 99m Sestamibi) was performed before the surgical operation. The histologic examination revealed 14 cases of breast cancer; 12 of these (86%) resulted positive after scintigraphy, while 2 were false negative. In this study, the scintigraphic exam and its diagnostic accuracy were analyzed, both in relation to anatomical structure of the mammary gland (thick breast, fibrocystic mastopathy, postsurgical scars, etc.) and also in relation to characteristics of the suspected node, the nature of which was not possible to determine from other exams carried out. In conclusion, after comparison between our experience and those reported in literature, we conclude that because of its high specificity and sensibility the mammoscintigraphy exam assumes an important comparative index in obtaining elements for an additional evaluation when other instrumental examinations are dubious.

[The switch prophylaxis with levofloxacin in surgical procedures for prosthetic inguinal hernia repair in one day surgery].

The installation of synthetic prosthesis in the repair of the hernial defects of the inguinal region, though it is part of cleaned surgical operations, it needs of an antibacterial prophylaxis for the prevention of the septic complications of the surgical wound and these, compared with complications following hernioplasty by straight suture, have a meaningful morbidity that can outweigh social and economic advantages of the hernioplasties. The Authors' experience is relative to 112 patients submitted to prosthetic hernioplasty by anterior approach (94 cases) and by transabdominal preperitoneal laparoscopy (TAPP) (18 cases) and underwent to "switch prophylaxis" with Levofloxacin using this posologic scheme: 500 mg ev 30 m' before the surgical operation and 500 mg os in seven days following. The evaluation of the surgical wound has never evidenced septic and suppurative complications; only 11 of the 122 surgical wounds (9%) have documented light phlogosis never advanced to evident suppuration. No patients have showed signs of pharmacologic local intolerance; about collateral general effects as sick and diarrhoea are appeared in 5% of patients, but these have been of light entity; an increase of the transaminase, quickly reverted to the suspension of the therapy, has interested 4% of cases. On the basis of these satisfactory results about clinical efficacy on the prophylaxis of the phlogistic complications of the surgical wound, with reduction of the incidence and gravity and in relation to large and complete antibacterial spectrum included Staphylococcus aureus and epidermidis, and about excellent tolerability without collateral effects, the Authors consider to be important the standardized use of this prophylaxis in the prosthetic hernial surgery of the inguinal region. This choice is correlated to the typical pharmacologic characteristics of the Levofloxacin and particularly to the total bioequivalence between endovenous and oral formulation and besides in relation to perseverance, not inferior to 24 hours, of the plasmatic and tissutal concentrations above bactericide IMC on the most part of organic districts, included skin and soft tissue. The assurance of Levofloxacin's employment in the "switch prophylaxis" also is correlated to patient's elevated compliance, above all if he is operated on regimen of "one day surgery", and to a favorable relationship between costs and benefits.

[Hemorrhage and gastric perforation in patients with percutaneous endoscopic gastrostomy (PEG)].

INTRODUCTION: PEG is more and more used for those patients who need a medium and above all long term enteral nutrition, especially at home. This is the closest technical system to the requirements to have an ideal nutritional access; however it is burdened, on average in 32.5% of cases, with complications linked to technical mistakes of positioning or to a wrong management, such as haemorrhage and gastric perforation. CASE REPORT: A patient, subjected to supraglottic laryngectomy, to removal of tongue's base and to bilateral laterocervical lymphadenectomy and PEG carrier for 4 months, has arrived to our observation for a clinical outline of acute abdomen for perforation of hollow internal organ, preceded by progressive anaemia due to high digestive haemorrhage. Performed an exploratory laparotomy, it was discovered on the gastric fore face, between body and antrum, in proximity to the small curvature and in front of the PEG gastric access, a perforation with max 2 cm of diameter, crossed by probe's internal disk of retention. They proceeded to remove that, to unstick the gastric stoma from the parietal peritoneum, to suture the access of gastrostomy and the perforation by omentoplasty. Finally they carried out a jejunostomy for enteral feeding. DISCUSSION: We think we can pathogenetically identify the cause of the haemorrhage and of the stomach's perforation, occurred in a short time in the case we have examined, in the probe's movement for incorrect fixing of the plate of external anchorage or for excessive slimming of the patient due to not balanced nutritional supply, as well as in the consequent extension of its intraluminal part with continuous rubbing by internal disk on the gastric wall and with onset decubitus ulcer. Physiopathologic moments, connected with the supposed etiological factor, make both occurred complications as an unique pathologic entity, which has to be observed in the PEG carriers, in order to be able to diagnose it and treat it precociously and above all in order to be able to prevent it. Only a correct technique of positioning and of nursing and of management of nutritional supply is able not to thwart the finality of the PEG device which can be considered, in the elective indications and for the favourable requisites that marks it, a valid access to enteral nutrition realization.

[Angiodysplasia in the gastrointestinal haemorrhage of the elderly patient. Our experience].

Angiodysplasia of the digestive tract is one of the main causes of acute bleeding and is a frequent reason for admittance to the emergency surgery unit. This pathology, previously considered rare and often not recognised, has only recently acquired a precise anatomo-pathology thanks to endoscopy. Besides having a decisive diagnostic role, endoscopy also allows the control and successful treatment of lesions, often in a definitive way, which were previously only dealt with surgery, with significant advantages for the elderly patient, reducing the rate of morbidity and mortality. There are still many discussions today, above all on the priority of various diagnostic investigations to be carried out in digestive bleeding and on the choice of treatment in the case of angiodysplasic lesions in geriatric age. Some cases of acute bleeding from intestinal angiodysplasia, observed by the Authors, have led them to study the etiopathogenesis, diagnosis and emergency treatment of such lesions.

[The capillary hemangioma of the stomach: an unusual cause of haemorrhage. Case report].

Gastric haemorrhages are common clinical emergencies which often directly involve the surgeon in diagnosis and treatment; among these, rare vascular neoplasms deserve particular attention. The Authors report a rare case of benign vascular tumour of the stomach, a capillary angioma. After a literature review they highlight the importance of specific exams to reveal these small neoformations which, generally, show up clinically with acute bleeding, which may be severe, and which may not be discovered if the clinical evaluation is not very detailed. The surgical excision supported by a frozen sections is the most effective treatment.

[Inguinal hernia repair in the elderly: modified Shouldice procedure, 10 years of experience].

Authors relate their experience of 10 years period (1984-1994) with Shouldice technique for inguinal hernia repair in the elderly. This technique, in the Author's clinical practice, replaced the Bassini operation. The personal series is costituted of 190 patients underwent to inguinal repair during a 10 years period from 1984 to 1994 with recurrence rate of 1.1% (2 pt.). Authors consider Shouldice operation to be most valid from the methods of direct suture, with lower recurrence range.

[Primary gastrointestinal localization of N-H lymphoma: authors' experience].

Primary non-Hodgkin lymphoma of the alimentary tract is a rare pathological entity with few peculiar clinical aspects, therefore characterized by problems of differential diagnosis with other neoplastic and inflammatory diseases. The Authors report on some cases of primary gastrointestinal N-H lymphoma observed in their experience and discuss about the most significant clinical and pathological data. They conclude that currently surgical treatment is the first fundamental step of a multidisciplinary therapeutic program, which may allow an improvement of the prognosis.
