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.

Liver resection for hemoperitoneum caused by spontaneous rupture of unrecognized hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is an increasingly common form of cancer. Although its spontaneous rupture is rare in Western countries, it constitutes a surgical emergency and is associated with high mortality. There is a lack of consensus as to the best approach and what parameters to use in choosing it. The three main approaches are conservative, endovascular and resection - the treatment of choice for acute abdominal bleeding. We report a case of hemoperitoneum following the spontaneous rupture of an unrecognized HCV-related HCC in a patient with no history of liver disease. The patient was successfully treated by emergency surgery, with resection of two segments of the left liver.

Steam gasification of tyre waste, poplar, and refuse-derived fuel: a comparative analysis.

In the field of waste management, thermal disposal is a treatment option able to recover resources from "end of life" products. Pyrolysis and gasification are emerging thermal treatments that work under less drastic conditions in comparison with classic direct combustion, providing for reduced gaseous emissions of heavy metals. Moreover, they allow better recovery efficiency since the process by-products can be used as fuels (gas, oils), for both conventional (classic engines and heaters) and high efficiency apparatus (gas turbines and fuel cells), or alternatively as chemical sources or as raw materials for other processes. This paper presents a comparative study of a steam gasification process applied to three different waste types (refuse-derived fuel, poplar wood and scrap tyres), with the aim of comparing the corresponding yields and product compositions and exploring the most valuable uses of the by-products.

[Gastrointestinal opportunistic infections and human immunodeficiency virus (HIV). Case report]. / Infezioni opprtuniste gastrointestinali e HIV. Caso clinico.

There have been millions of people found to have AIDS. Death rates from AIDS have declined 15% to 20% in the past 5 years. However, nearly 75000 people will die with AIDS in this year. Patients with AIDS are also at risk for developing both Aids-defining cancers, such as Kaposi's sarcoma and non-Hodgkin lymphoma, and non-Aids-defining cancers and opportunistic infections. In patients with advanced Aids, the Cytomegalovirus is a frequent cause of chorioretinitis, pneumonitis, chronic perineal ulcerations and oesophagitis. It has been involved in endocrine, bone marrow, central nervous system and kidney abnormalities. CMV infection of the small bowel accounts for only 4.3% of all cytomegalovirus infection of the GI tract (large bowel 47%, duodenum 21,7%, stomach 17,4%); isolated cases of small bowel perforation due to CMV have been reported in AIDS patients, and all but one patient died. The Authors report a rare case of an HIV-positive young man with gastroenteric Cytomegalovirus infection responsible for generalized peritonitis from multiple perforations.

[Total thyroidectomy: initial experience of a territorial reference center]. / La tiroidectomia totale: esperienza iniziale di un centro di riferimento territoriale.

Authors report their initial experience in surgical treatment of thyroid diseases in an area with high percentage of thyroid tumors. Since January 2006, we examinated 428 patients. By clinical features, hormonal profile, imaging and US-guided FNAB, we selected 134 of them for surgery; 93 patients underwent thyroidectomy in January-November 2006. The Authors analyse therapeutic choises and surgical techniques, stressing the high percentage of thyroid neoplasms.

[Traumatic retroperitoneal haematoma]. / L'ematoma retroperitoneale post-traumatico.

The management of traumatic retroperitoneal haematomas is still a much debated question. Although the diagnosis has become easier using CT with contrast medium, the therapeutic decisions are still difficult because of the great variability of the lesions, which may be simple but very often complicated. Our study is based on 1086 treated patients, 29.5% of the 3682 critical abdominal polytrauma seen in 35 years. Mortality has been 12.9% with a medium ISS (Injury Severity Score) of 23.4. 71.4% of the cases were closed traumas, 28,6% were open traumas. The most common single lesions have been pelvic (43%), followed by the renal traumas (39%). Regarding the associated lesions, the thoracic traumas cause an increment of the ISS score up to 26.2% and of mortality up to 14.6%. The maxillofacial traumas associated with traumatic retroperitoneal haematomas represent 11%, mainly associated with motorcycle accidents, which have increased in the last years from 2,4% in the 70s to 32% these days. Our approach to these patients has been basically conservative. Following the indications obtained by the CT, we widely used interventional angiography, especially for renal lesions and, after pelvic stabilization, for pelvic haematomas. We have chosen surgery considering the kind of traumas (open or closed), the location of the haematoma and especially, the clinical course of the patient's hemodynamic condition.

Delayed Introduction of Everolimus in De Novo Renal Transplanted Patients: A Single-Center Experience.

INTRODUCTION: Immunosuppressive protocols containing everolimus (EVR) preserve good renal function in kidney transplantation (KT), although they are often complicated by several adverse events. We have evaluated the efficacy and safety of a protocol with late (1 month after KT) EVR introduction. MATERIAL AND METHODS: This study randomized 49 de novo patients undergoing KT between September 2012 and June 2014 into 2 groups: group A (n = 24) with late EVR introduction and tacrolimus reduction, and group B (control group; n = 25) with a standard immunosuppressive regimen. Primary aims were 1-year patient and graft survivals and acute rejection rates. Secondary aims were related to wound, metabolic, and hematologic complications. RESULTS: Patient and graft survivals were similar in both groups. One year after KT, median serum creatinine was inferior in group A (1.4 vs 1.8 mg/dL; P = .004). Late acute rejection (8.3 vs 12.0%; P = 1.0) and wound complication (4.2 vs 4.0%; P = 1.0) rates were similar. Higher cholesterol and triglycerides and lower platelets and hemoglobin levels were observed in group A. CONCLUSIONS: In our experience, delayed introduction of EVR shows similar results with respect to its early introduction, contemporaneously presenting fewer wound complications and lymphoceles. A higher rate of metabolic and hematologic complications are, however, observed in patients under EVR therapy. Further multicenter studies should be performed to confirm these preliminary results.

Predictive factors of outcome after liver transplantation in patients with cirrhosis and hepatocellular carcinoma.

Studies to define the optimal upper limits of tumor size and number as predictors of outcome after orthotopic liver transplantation (OLT) have yielded conflicting results. We analyzed 72 patients with cirrhosis and hepatocellular carcinoma (HCC) who underwent OLT over a 12-year period in a single center. Predictive factors for survival and tumor recurrence, according to the Milan criteria, were also examined. Our cohort included 60 men and 12 women of mean age 54 +/- 8 years and mean follow-up of 40 +/- 39 months. Origin of cirrhosis was postviral in 70% and Child class B or C in two thirds of patients. HCC was multifocal in 61%; about one fifth of patients had micro- or macrovascular involvement or positive nodes upon histologic examination. The cumulative size of the lesions was <3 cm in 17 patients; >3 to < or =5 cm in 28 patients; >5 to < or =8 cm in 14 patients; and >8 cm in 13 patients. According to the number and size of tumor nodules, 49 patients met the Milan criteria. During follow-up 25 patients died, 13 due to tumor recurrence. The 1- and 2-year survivals were 90% and 85% for patients who met the Milan criteria versus 57% and 51% for patients exceeding those limits (P = .006). A cumulative tumor size >8 cm was predictive of survival and tumor recurrence upon multivariate analysis. The adoption of Milan criteria for selection of cirrhotic patients has improved survival and reduced the rate of tumor recurrence. The evaluation of cumulative tumor size might further improve patient selection.

Survival in kidney transplantation from living donors: a single-center experience.

BACKGROUND: Transplantation from living donors, in Italy, is still not accepted, in particular those from unrelated donors. The aim of this paper was to present the experience of one transplant center. MATERIALS AND METHODS: Since 1982, 608 transplants were performed from living donors using cyclosporine as the main component of immunosuppressive therapy. Among those, 402 transplants were from related living donors (338 one haplotype pairs and 25 zero haplotypes pairs) and 206 from unrelated living donors (171 spouses and 35 emotionally related subjects). RESULTS: Graft survival at 1, 5, and 10 years showed no statistically meaningful difference between the two groups. A group of 19 transplants performed in predialytic phase patients was compared with a contemporaneous group of 167 transplants performed in patients who were already receiving dialysis. These two groups did not show any statistically meaningful difference in graft survival at 1, 5, or 10 years. DISCUSSION AND CONCLUSIONS: We think that transplants from living donors, whether related or unrelated, must always be proposed as a therapeutic option for end-stage renal disease patients, since they show an higher graft survival than that from cadaveric donors, independent of the compatibility between donor and recipient and independent of the degree of relationship of the pair. Transplantation from living donors definitely is a complementary, not substitutive, program to that from cadaveric donors, which should always be encouraged with awareness campaigns among the population and targeted programs for healthy personnel.

Recurrence of hepatitis C virus infection after orthotopic liver transplantation: role of genotypes.

In this study, we evaluated the correlation between alanine aminotrasferase levels and hepatitis C virus genotypes in liver transplant patients. We studied 18 patients who had undergone orthotopic liver transplantation because of end-stage cirrhosis (n = 9) or hepatocellular carcinoma (n = 9) hepatitis C virus related. Serum HCV-RNA testing was performed monthly on all the 18 series of serum samples from the first week after liver transplant until the end of the follow up, this period ranging from 1 to 39 months. After liver transplantation, serum HCV-RNA was detected in 14 patients (78%). Of the 8 patients infected with subtype 1b. 1 remained asymptomatic, 2 developed acute liver failure and 5 developed chronic hepatitis. In patients infected with types 1a (Choo et al., 1989), 2a (Choo et al., 1989), with a mixed infection 1b/3 (Kuo et al., 1989) or with an undetermined genotype, significant laboratory abnormalities were not observed. Recurrence of hepatitis C virus infection after liver transplantation is common, and recurrent hepatitis occurs in 50% of cases. Genotype 1b appears to be associated with a higher rate of recurrent hepatitis, compared to other genotypes.

[Transplantation of the pancreas: surgical aspects]. / Il trapianto di pancreas: aspetti chirurgici.

Based on their personal as well as international experiences, the authors describe different surgical techniques employed in pancreatic allograft related to different complications rate and patient and graft outcome. In fact, the surgical technique represents an only partially solved problem, because of the high percentage of complications dealing with the different approaches. Even though several procedures concerning either the site of implantation either the treatment of the exocrine function have been so far used, the results up to now obtained are the main limiting factor for a large clinical application of pancreatic transplantation.

[The evolution of immunosuppression in clinical kidney transplantation: the experience of 700 cases]. / Evoluzione dell'immunosoppressione nel trapianto clinico di rene: esperienza su 700 casi.

Kidney transplantation was first introduced in Italy in 1966 by the II Surgical Pathology of the University of Rome giving a great contribution to the development of the transplant surgery in this country. The authors report their 25-year experience analyzing the results obtained in more than 700 kidney allografts. A progressive refinement in the surgical transplant technique both from cadaver and live as well as clinical trials on new immunosuppressive protocols characterized their work.

[Surgical technique aspects in multiorgan transplantation: personal experience]. / Aspetti di tecnica chirurgica del trapianto multiorgano: esperienza personale.

The Authors report their experience with multiorgan transplantation performed in 3 patients affected by multifocal cancer of the liver, either primitive (2 cases) or secondary (1 case). The rationale for this new approach was the unfeasible single liver transplantation taking into account the extracapsular diffusion of the neoplasia.
