Small bowel intussussception due to metastatic melanoma of unknown primary site. Case report.

Malignant melanoma is characterized by metastases also to the gastrointestinal tract, especially in the small bowel. The diagnosis is often delayed because unspecific clinical presentation (frequently as chronic iron deficiency anemia, rectal bleeding or intestinal obstruction). We present a case of melanoma of unknown primary site, with clinical presentation of intestinal obstruction. A segmental resection of the ileum was performed including mesentery with lymph nodes. Histology revealed metastatic melanoma from unknown primary. PET and MRI confirmed disseminated disease without brain metastasis.

Biliodigestive fistulae and gallstone ileus: diagnostic and therapeutic considerations. Our experience.

The biliodigestive fistula is not a rare affection in the context of acute pathology of the gastrointestinal tract. It often affects patients between 63 and 85 years old , particularly the female sex, and the most common cause is acute or chronic cholecystolithiasis. Open issues are the delayed in the pre-operative diagnosis, and controversies exist regarding the best surgical approach. The choice of treatment options is influenced by the age of the patients and their clinical conditions and also by the presence of comorbidities and of a delayed right diagnosis. In the 1 to 3% of cases, the biliodigestive fistula presents a gallstone ileus as complication, whose diagnosis is particularly difficult for the lack of specific signs and symptoms. The contrast-enhanced CT is considered the gold standard for a specific pre-operative diagnosis, as it directly shows the fistula. Surgical treatments include one-stage procedure or two-stage procedure. Many studies seem to favor a deferred definitive procedure. The Authors describe 4 cases: in 3 cases, women between 70 and 80 years old presenting an history of recurrent cholecystitis, in 2 cases, and in 1 case presenting a bowel obstruction; in 1 case a 50-years-old man, with no significant past medical history, presenting a bowel obstruction. The Authors have performed in the 2 cases of gallstone ileus an enterolithotomy with cholecysto-duodenal fistula repair and cholecystectomy, in one-stage, and this has been possible because of the good clinical conditions of the patients and their low operative risk. In the case of fistula without the complication of gallstone ileus, the treatment approach has been cholecysto-gastric fistula closure with a gastroplastic using separate stitches and cholecystectomy, in one-stage. We are in agreement with data in the literature regarding the delay into the diagnosis of biliodigestive fistula and with the importance to suspect it or gallstone ileus presence, although the clinical presentation is extremely non-specific. In our experience, cholangiopancreatography-CT and CECT have made easier the pre-operative diagnosis and so reducing the delay of the treatment.

Technique and outcomes about a new laparoscopic procedure: the Pelvic Organ Prolapse Suspension (POPS).

Pelvic organ prolapse suspension (POPS) is a recent surgical procedure for one-stage treatment of multiorgan female pelvic prolapse. This study evaluates the preliminary results of laparoscopic POPS in 54 women with a mean age of 55.2 and a BMI of 28.3. Patients underwent at the same time stapled transanal rectal resection (STARR) to correct the residual rectal prolapse. We had no relapses and the preliminary results were excellent. We evaluated the patients after 1 year follow-up and we confirmed the validity of our treatment. The technique is simpler than traditional treatments with an important reduction or completely disappearance of the pre-operative symptomatology.

Risk management in surgery.

Malpractice is the responsible for the greatest number of legal claims. At the present time, legal actions against physicians in Italy are 15,000 per year, and a stunning increase about costs to refund patients injured by therapeutic and diagnostic errors is expected. The method for the medical prevention is "Risk Management", that is the setting-up of organizational instruments, methods and actions that enable the measurement or estimation of medical risk; it allows to develop strategies to govern and reduce medical error. In the present work, the reconstruction about the history of risk management in Italy was carried out. After then the latest initiatives undertaken by Italy about the issue of risk management were examined.

Single-incision laparoscopic appendectomy is comparable to conventional laparoscopic and laparotomic appendectomy: our single center single surgeon experience.

Several studies have demonstrated the clinical and technical benefits of the laparoscopic surgery for complicated and uncomplicated appendicitis. Our retrospective study included 12 patient who underwent SILS appendectomy (SILS-A), 14 who received conventional laparoscopic surgery (VL-A), and 12 who received laparotomic appendectomy (OA); performed in all cases by the same surgeon (C.F.). The aim of this study was the comparison between this three different surgical techniques on same features: post operative leukocytosis, post operative pain, need abdominal drainage, esthetic viewpoint, incidence of complication, hospital stay. The results showed no significant differences between SILS-A and VLS-A, while an evident improvement shows versus O-A, even though not statistically significative. SILS was more effective in decreasing the risk of postoperative wound infection.

Re-sleeve Gastrectomy 4 Years Later: Is It Still an Effective Revisional Option?

Laparoscopic sleeve gastrectomy (LSG) is the most performed surgical procedure worldwide. Long-term outcomes report that up to 30% of patients require revisional surgery and re-sleeve gastrectomy (rLSG) is one of the revisional procedures available. The aim was to update the outcomes of a cohort of rLSG at 52 months. This study reports the 52-month follow-up of a cohort of 19 patients previously published after 24-month follow-up. Sixteen patients completed the follow-up. Nine patients complained of GERD symptoms after 36 months. Five patients were converted to laparoscopic RYGB. Two patients were converted to a laparoscopic BPD-DS for weight regain 4 patients are asymptomatic with stable weight. On the basis of our disappointing results, it can be said that rLSG is not currently offered as revisional procedure in both centers.

A comparison of dietary behaviour in Central England and a French Mediterranean region.

UNLABELLED: BJECTIVEe: The investigation involves comparison of dietary behaviour between UK and Mediterranean France by characterizing the pattern of the current French Mediterranean diet compared with the current British diet. DESIGN: The findings of two dietary surveys, one in the UK and one in France, are compared. An interviewer-administered questionnaire was used in both countries. Questions on food frequency were used to assess dietary behaviour, which were regrouped in the French survey to correspond with UK groupings. Dietary indices were constructed to describe dietary behaviour in relation to cancer recommendations for intake of fat, fibre, meat, fruit and vegetables. SETTING: The UK study was conducted in Leicestershire, central England and the French study was carried out in Hérault, southern France. SUBJECTS: UK: n=418 subjects (57.9% female and 42.1% male; mean age=45.0 y); France: n=635 subjects (50.1% female and 40.9% male; mean age=49.8 y). Age range of both samples: 20-74 y. RESULTS: There were positive and negative trends in food consumption in each country. UK respondents reported eating more beans and pulses (P=0.000), less cheese (P=0. 000), red meat (P=0.001), and processed meats (P=0.000) than French respondents. However, on the negative side, they ate less fruit and vegetables (P=0.000), fish and poultry (P=0.000), cereals (P=0.000), and more sweets and chocolates (P=0.000), and cakes, pastries, biscuits and puddings (P=0.000). Women had healthier diets in both countries. CONCLUSIONS: Overall the southern French diet was healthier as French respondents scored significantly better for indices for fat, dietary fibre, fruit and vegetables (P=0.000 in all cases). However, the French sample scored poorer for the meat index (P=0.000). SPONSORSHIP: This study was supported by a grant from l'Association de la Recherche contre le Cancer (ARC) awarded to M Holdsworth.

Mammary hamartomas: an immunohistochemical study of ten cases.

Ten cases of breast hamartomas were reviewed; the patients' age ranged from 31 to 55 (mean 40.4, median 39). All cases presented with a palpable, sometimes tender, lump. The typical mammographic feature was a well defined, round to lens shaped, variable dense mass, occasionally surrounded by a thin radiolucent zone. All hamartomas were unilateral (4 in the right and 6 in the left breast, respectively) and no recurrence occurred after local excision. The tumor size ranged from 5 to 150 mm (mean 54 mm). Histologically all hamartomas were composed of a typical fibrous, adipose and glandular tissue combination. Immunohistochemically there was a strong positivity for cytokeratin and epithelial membrane antigen in the epithelial cells, a positive finding for vimentin and muscle-specific actin in stromal and myoepithelial cells, and for S-100 protein in myoepithelial cells. Vessels endothelial cells were immunoreactive for Factor VIII. Immunohistochemical analysis of hormone receptors completed on formaldehyde-fixed paraffin-embedded specimens, showed estrogen and progesterone receptors positivity in 9 cases and estrogen positive progesterone negative receptors in one case. In all cases the receptorial positivity was limited to the epithelial elements. These data revealed that 1) breast hamartoma is a benign, tumor-like lesion, histologically dissimilar from other lesions such as fibroadenoma and pseudoangiomatous hyperplasia; and 2) hamartoma tissue is influenced by hormones like the surrounding normal breast parenchyma.

[Benign lesions of the breast]. / Lesioni benigne della mammella.

Benign lesions represent the most frequent lesions of the breast. Such lesions often onset with nodules or palpable masses simulating a breast cancer. In uncertain cases, an excisional biopsy may be at the same time a diagnostic and a therapeutic solution. A high percentage (40%) of the diagnosed lesions belongs to fibrocystic disease. A remaining 50% can be shared among tumor-like lesions, inflammatory lesions or benign tumors like fibroadenomas. Only in the 10% of palpable breast masses, biopsy reveals a breast cancer. The role of the pathologist is strictly related to the surgeon's one. Clinically benign lesions may be excised throughout a biopsy performed under local anesthesia. Clinically uncertain lesion must be evaluated by a fine needle aspiration biopsy (FNAB), nevertheless in some cases the doubt may persist. In such cases an excisional biopsy performed while the patient is under general anesthesia may finally solve the question. In case of breast malignancies the intervention can be enlarged as described for cancer.
