Inguinal hernia repair is one of the most common surgical procedure performed in Western countries and it consumes a lot of healthcare resources. Several types of different mesh are now disposable and tension-free techniques represent the “golden standard”. In our study, fifty male patients were operated on for inguinal hernia and a PAD (i.e., dynamic self-regulating prosthesis) used for the repair of the inguinal defect: this technique demonstrated to be safe, effective and easy to perform.

Situs viscerum inversus totalis is a rare defect with a genetic predisposition, which can present difficulties in the management of abdominal pathology, especially in laparoscopic surgery (mirror-image anatomy). We report the case of a 52-year-old female with situs viscerum inversus totalis, known from pediatric age, with a medical history of colic pain in the epigastrium radiating to the right abdominal quadrant. Laparoscopic cholecistectomy was safely performed with a three trocar technique. To the best of our knowledge this is the first time that laparoscopic cholecistectomy by three trocars was performed in a patient with situs viscerum inversus. We also review the relevant literature concerning this issue.

In the last years there has been a growing demand of plastic surgery for soft tissue reconstruction. In response to this, many biological and synthetic devices have been produced, aiming to allow wide and complex body reshapings. Acellular dermal matrices are one of these devices, and are made of human or animal tissues made acellular after their sampling. They are used for cervical, breast and abdominal wall reconstruction. Tutopatch®, generally used for face reconstruction or neurosurgery, is made of acellular bovine pericardium, and its high amount of collagen allows a fast tissue healing and a scaffold for the surrounding tissue rigeneration. In our case report Tutopatch® has been used in immediate breast reconstruction after mastectomy. This device has been used to close laterally the subpectoral pocket, allowing a bigger volume prosthesis to be placed We have not experienced particular postoperatory complications, and after 12 months of follow up we have found a valid functional and aesthetic result. We consider Tutopatch® as a valid alternative to other acellular dermal matrices specifically designed for breast reconstruction.

Il progetto Sicily in Transition è nato dalla collaborazione delle Università di York e di Roma Tor Vergata, con il pieno ap-poggio della Soprintendenza ai BB. CC. AA di Palermo. La finalità della nostra ricerca è quella di analizzare, attraverso il registro archeologico, in quale modo i mutamenti di regime politico hanno influenzato organizzazione, composizione e stili di vita delle popolazioni soggette. L’arco di tempo considerato va dal VI al XIII secolo, periodo nel quale la Sicilia ha visto diverse dominazioni: quella bizantina, islamica, normanna e sveva. Sicily in Transition prevede di analizzare con metodi in parte nuovi, in parte più tradizionali, sia insiemi di reperti (ecofatti e manufatti) prodotti da precedenti scavi, sia di acquisire dati attraverso nuove indagini. In particolare gli scriventi hanno scelto di indagare un’area molto promettente della Sicilia centrale: il territorio di Castronovo di Sicilia. Qui, in due campagne di ricerca durate ciascuna quattro settimane, sono state realizzate indagini magnetometriche, ricognizioni di superficie, di archeologia dell’architettura e sondaggi stratigrafici. La finalità era quella di valutare il potenziale archeologico dei principali siti storici del territorio. I primi risultati sono promettenti in relazione alla varietà tipologica e cronologica dei diversi insediamenti identificati: una fortezza dei secoli VII-IX sul Monte Kassar; un fortilizio con fasi del pieno medioevo e dell’età moderna sul Colle San Vitale; un ampio villaggio non difeso con fasi dall’età tardoantica al medioevo, incluse importanti testimonianze di età islamica, nell’area del Casale San Pietro. Le indagini preliminari hanno quindi confermato le ampie potenzialità informative dell’intero territorio di Castronovo rispetto ai temi della nostra ricerca e stanno quindi consentendo di programmare gli interventi futuri.

The aim of this study was to collect information on the incidence, pathophysiology, treatment and mortality of pneumothorax in the Emergency Room. Pneumothorax is classified as spontaneous (primary, secondary or catamenial) or traumatic (iatrogenic or secondary to a blunt or penetrating chest injury). Between January 2007 and December 2009, 102 patients with pneumothorax were seen in our Emergency Room. Their records were examined and their data collected retrospectively. The type and side of the pneumothorax and age, sex, incidence and mortality were analyzed. The cases, involving 93 males and 9 females, broke down as follows: 68 spontaneous (66.7%), 33 traumatic (32.3%) and one iatrogenic (0.98%). The mean age was 47.3 (range 12-99); the incidence was 0.10%. There were no deaths due to pneumothorax in the Emergency Room. Traumatic pneumothorax was associated with blunt chest trauma, pleural effusion, hemothorax, cranial trauma, fractured collarbone, upper and lower limb fracture, pelvic fracture, vertebral and spinal trauma, sternum fracture and abdominal trauma. Pneumothorax is a common clinical problem. A multidisciplinary approach is essential to reduce the risk of morbidity and mortality. The incidence of pneumothorax in the Emergency Room was similar to that reported in the literature, while mortality data cannot be compared due to the lack of published studies.

Wernicke syndrome is a rare neurological pathology due to a deficit in vitamin B1. The syndrome is common among alcohol abusers, patients with malignant tumor or gastrointestinal diseases, those who undergo hemodialysis or long-term peritoneal dialysis, pregnant women with hyperemesis, women who breast-feed, patients with hyperthyroidism or anorexia nervosa or gastric or jejunal-ileal bypass surgery for obesity, patients submitted to gastric surgery or prolonged total parenteral nutrition or prolonged intravenous therapy. We report a case of Wernicke syndrome due to afferent loop syndrome characterized by incoercible vomiting.

We report the case of a 82-year-old woman, asymptomatic, subject to chest computed tomography for trauma. Then the patient underwent surgery. Before sternotomy, femoro-femoral bypass was starter in order to decompress the aneurysm; using deep hypothermia and circulatory arrest, ascending aorta and hemiarch replacement were performed with a Dacron graft. Post-operative course was uneventful.

Type I Neurofibromatosis (NF1) is an autosomal-dominant inheritable disorder, with an incidence of 1:3,000, and a prevalence of 1:4,000 to 5,000. Pathogenesis is based on mutations of the NF1 gene, a tumor suppressor gene encoding a cytoplasmic protein named neurofibromin that controls cellular proliferation. Patients affected by NF1 typically present with cutaneous neurofibromas, cafè au lait spots and eye involvement, but they can also be affected by various visceral tumors, such as neurofibromas (nodular or plexiform type), gastrointestinal stromal tumors or endocrine tumors, such as pheochromocytomas. Visceral neurofibromas are often asymptomatic but when growing in size they may present with pain, palpable abdominal mass, symptoms secondary to bowel obstruction or main vessels compression, and even gastrointestinal bleeding when mucosa or submucosa are involved. In these cases surgery becomes mandatory in order to remove all neoplastic tissue. The Authors describe a case of a young man affected by NF1 with associated retrocaval abdominal mass with compression and displacement of the inferior vena cava, thus requiring a complex surgical procedure.

Small bowel obstruction (SBO) is a very common condition, in the vast majority of cases caused by post-operative adhesions. It often requires surgical treatment. Traditionally, this consisted of a laparotomy, but nowadays a laparoscopic approach is also possible. This study discusses 24 cases of SBO and compares them with literature data. Successful complete laparoscopic treatment was feasible in 9 patients, while conversion to laparoscopically-assisted surgery or laparotomy was required for the others.

Introduction. Routine use of nasogastric tubes (NGT) after abdominal operations is intended to hasten the return of bowel function, diminish the risk of anastomotic leakage and prevent pulmonary complications. The aim of our study was to prospectively assess the tolerability and the safety of the non use of NGT after elective colorectal open operations. Patients and methods. Between March 2009 and December 2010, 110 consecutive patients underwent colo-rectal elective open surgery for neoplasm without nasogastric decompression. We analyzed the incidence of nausea and vomiting, the pulmonary complications, the return of bowel function the deep wound breakdown (fascial dehiscence) and the anastomotic leakage. Results. Only 15 patients (13,6%) reported nausea without vomiting immediately after surgery and 9 cases of vomiting were observed (8%), requiring the insertion of the NGT (nasogastric tube) in 5 (4,5%). A total of 105 patients (96,3%) were NGT free. No deep wound dehiscence was observed and only one real pneumonia occurred. Anastomotic dehiscence occured in 4 patients (3,6%) and a second surgical procedure was needed in three cases. The return of bowel function, except in the last four patients, occurred in 3,8 days average (range 2-7 days). Conclusion. We confirm the uselessness of the NGT in the framework of fast track program adopted in elective open colo-rectal surgery.

aparoscopic surgery plays today an important role in the diagnosis and staging of abdominal lymphomas; in fact it provides adequate lymph node sampling for histological typing and immunophenotyping. The mini-invasive procedure is safe and effective. Intra-operative ultrasound permits to study the parenchimal organs in addition to intra-abdominal lymph node and/or masses.

Introduction. Breast phyllodes tumors (PT) are uncommon fibroepithelial lesions having potential malignant features. These tumors have characteristic features, like phleomorphism, mitoses and overgrowth of the stroma with possible infiltrative margins. The clinical behaviour could be unpredictable, since the relatively high recurrence rate despite correct surgical strategy. Conventional diagnostic examinations show high sensitivity and specificity, but cannot demonstrate the differences between benign and malignant PT. MRI is not more effective. Patients and methods. Sixteen patients affected by PT have been surgically treated at our Institution. All patients received mammography and ultrasonography (US) as preoperative diagnostic work-up. Results. in 13 patients, US was effective in preoperative diagnosis of PT. Mammography was uneffective in detecting breast lesions in 5 cases, while in 11 cases mammographic findings presented benign features, with a round opacity with moderate tissue density and well-defined wall. Conclusion. US remains the most useful diagnostic test in detecting PT. However, there is no test effective in identifying malignat PT. In case of suspicion, fine needle biopsy should be performed.

Aim. Carotid artery stenting (CAS) is the treatment of choice for recurrent stenosis after carotid endarterectomy (CEA). However a significative incidence of in-stent restenosis could be occurred. Despite classical CEA leads to good results, in selective cases bypass graft may be the best treatment of in-stent restenosis. Case reports. We describe two cases of carotid bypass graft performed to treat a recurrent in-stent stenosis after CAS for post-CEA restenosis. No death and cardiac complication occurred and no cranial nerves impairment was detected. Conclusion. Prosthetic bypass graft is safe and effective in treatment of in-stent recurrent restenosis after CEA restenosis.

Objective. To analyze clinical and laboratory findings in order to find variables predictive of severity of Biliary Peritonitis (BP). Patients and methods. Physical findings, course of illness, imaging and laboratory data were evaluated in 42 patients with BP, and statistically analysed to assess their prognostic significance. Results. Serious illness and worse outcome were associated with: age ≥ 60 years (P=0.034), long time between onset of symptoms and treatment (P=0.025), fever > 38°C (P=0.009), WBC count > 17,000 cell/mm³ (P=0.043), diffuse abdominal pain (P=0.034), and infected bile (P=0.048). Conclusions. Most patients become severely ill due to supervening infection, while early bile drainage avoids serious complications. In addition, abdominal pain, fever and WBC count are also predictive of severity of BP.
