Introduction: A prospective survey to evaluate the diagnostic workup of cystic pancreatic neoplasms (CPNs) according to the Italian guidelines.

Methods: An online data sheet was built.

Results: Fifteen of the 1385 patients (1.

Retrospective multicenter study of post-operative stenosis after stapled colorectal anastomosis.

Anastomotic stenosis after colorectal surgery is usually considered low-rate complication and often is under-reported in most studies. Few data are available on management strategies. The aim of the study was to assess the prevalence of stenosis after stapled colorectal anastomosis, performed either in elective or emergent setting, for benign or malignant disease, and to evaluate treatment profiles.

Spontaneously metachronous ruptures of adrenocortical carcinoma and its contralateral adrenal metastasis.

Adrenocortical carcinomas (ACCs) are rare neoplasms. In spite of its rarity, ACCs are the second most lethal endocrine cancer after anaplastic thyroid carcinomas. Currently, the only chance for a cure is an early diagnosis and a radical surgical resection.

Accuracy of magnetic resonance cholangiography compared to operative endoscopy in detecting biliary stones, a single center experience and review of literature.

Aim: To compare diagnostic sensitivity, specificity and accuracy of magnetic resonance cholangiopancreatography (MRCP) without contrast medium and endoscopic ultrasound (EUS)/endoscopic retrograde cholangiopancreatography (ERCP) for biliary calculi.

Methods: From January 2012 to December 2013, two-hundred-sixty-three patients underwent MRCP at our institution, all MRCP procedure were performed with the same machinery. In two-hundred MRCP was done for pure hepatobiliary symptoms and these patients are the subjects of this study.

Twelve years of experience treating Spigelian hernia.

Background And Aims: A Spigelian hernia (SH) is an acquired ventral hernia that most commonly occurs in the Spigelian belt. Patients may experience pain or a bulge in the abdominal area, but in most cases there are no symptoms. If left untreated the hernia may become strangulated, which could lead to bowel obstruction.

Neoadjuvant strategies for pancreatic cancer.

Pancreatic cancer (PC) is the fourth cause of cancer death in Western countries, the only chance for long term survival is an R0 surgical resection that is feasible in about 10%-20% of all cases. Five years cumulative survival is less than 5% and rises to 25% for radically resected patients. About 40% has locally advanced in PC either borderline resectable (BRPC) or unresectable locally advanced (LAPC).

Magnetic resonance enterography for Crohn's disease: what the surgeon can take home.

Background: Crohn's disease (CD) is a life-long, chronic, relapsing condition requiring often morphological assessment. MR enterography (MRE) offers advantages of not using ionizing radiation and yielding intraluminal and intra-abdominal informations. The aim of our study was to identify how MRE can be useful in planning surgical procedures.

Colonic carcinogenesis in IBD: molecular events.

Patients with ulcerative colitis (UC) and Crohn's disease (CD) are at increased risk of developing intestinal cancers via mechanisms that remain incompletely understood. Several evidences suggest a causal link between chronic inflammation and the development of cancer in the gastrointestinal tract. In fact, patients with UC are exposed to repeated episodes of inflammation that predispose to various tumorigenic events and the sequence of these events are different from those that contribute to develop a sporadic colorectal cancer.

Pathology of dysplasia and cancer in inflammatory bowel disease.

In both Crohn's disease and ulcerative colitis, colorectal cancer (CRC) secondary prevention basically relies on the histology detection of dysplasia. In inflammatory bowel diseases (IBD) setting, dysplasia identifies the subgroup of patients eligible to a (more) strict surveillance program (or prophylactic colectomy). In the clinical practice, a number of issues might affect the benefit of the clinico-pathological surveillance of the IBD-dysplasia-patients: sampling errors, inconsistency in biopsy assessment, patients' drop-out, etc.

Dysplasia in ulcerative colitis: still a challenge.

As duration of inflammatory bowel disease (IBD), in particular ulcerative colitis (UC), is a major risk factor for the development of colorectal cancer (CRC), it is rational to propose a screening colonoscopy when the risk starts to increase, i.e., after 8-10 years from the onset of disease.

Is laparoscopic cholecystectomy safe for lymphangioma of the gallbladder? A complicated case mimicking subhepatic abscess.

Lymphangiomas are rare benign neoplasms of the lymphatic tissue generally occurring in the childhood. Cystic lymphangioma of the gallbladder is an extremely rare tumor with only eight cases having been reported in the literature. The aspecific and potentially misleading clinical presentation of these tumors requires complex preoperative imaging in the setting of clinical suspicion to make the correct diagnosis.

Ileorectal bypass performed entirely through a transanal route in a porcine model.

Background: Natural orifice transluminal endoscopic surgery (NOTES), a new frontier of minimally invasive surgery, uses the body's natural orifices to create an access for surgical procedures. This study aimed to verify the technical feasibility of ileorectal bypass performed entirely through a transanal access.

Methods: The procedure was performed on 10 domestic pigs, after which they were killed.

Diode laser treatment of Barrett's esophagus: long-term results.

Different ablation techniques have been utilized in the treatment of Barrett's esophagus (BE) to reduce the risk of degeneration. Treatment complications, risk of recurrence, and buried intestinal metaplasia (IM) are all major concerns. The effect of diode laser treatment on BE, studied in a group of patients over a long-term period, is presented here.

The results of surgery for mediastinal parathyroid tumors: a comparative study of 63 patients.

Purpose: Parathyroidectomy for ectopic mediastinal hyperfunctioning glands could be performed by transcervical approach, sternotomy, thoracotomy, and recently by thoracoscopic and mediastinoscopic approaches. This study was aimed to analyze the results of traditional and video-assisted parathyroidectomy for mediastinal benign hyperfunctioning glands.

Methods: Fifty-one upper mediastinal exploration by a conventional cervicotomy, 12 by video-assisted approaches (two thoracoscopy and 10 transcervical mediastinoscopy) and six by sternotomy were performed in 63 patients with primary hyperparathyroidism.

Endovascular treatment of acute pseudoaneurysm associated to pancreaticoduodenectomy.

The study aim is to confirm feasibility and usefulness of endovascular stent-graft placement for superior mesenteric artery acute bleeding in presence of local sepsis. A superior mesenteric artery resection concomitant to a pancreaticoduodenectomy for carcinoma of the pancreas was followed by a saphenous vein bypass. A pancreatic leak associated to infection developed early in the postoperative course.

Deep venous thrombosis after surgery for inflammatory bowel disease: is standard dose low molecular weight heparin prophylaxis enough?

Background: Inflammatory bowel disease (IBD) and colorectal surgery are risk factors for deep venous thrombosis (DVT). The aim of this prospective study was to evaluate the effectiveness of standardized prophylactic low molecular weight heparin (LMWH) therapy in patients who underwent surgery for ulcerative colitis (UC) and Crohn's disease (CD).

Patients And Methods: Since 1999 all patients operated on for colorectal diseases in our institute have received 4,000 IU/day LMWH from the day of operation to discharge.

The hostile neck does not increase the risk of carotid endarterectomy.

Introduction: Hostile neck anatomy is assumed to be associated with increased surgical risk for patients undergoing carotid endarterectomy (CEA) and is often considered a reason to choose carotid stenting or medical management. This retrospective case-control study evaluated whether, and how much, anatomically hostile necks represent a condition of higher surgical risk of early and late mortality and major or minor morbidity.

Methods: The data for 966 homogeneous CEA patients was prospectively entered in a computer database.

Health-related quality of life after colonic resection for diverticular disease: long-term results.

Background And Aims: While colonic resection is standard practice in complicated colonic diverticular disease (DD), treatment of uncomplicated diverticulitis is, as yet, unclear. The aim of the present study was to evaluate the long-term clinical outcome and quality of life in DD patients undergoing colonic resection compared to those receiving medical treatment only.

Patients And Methods: Seventy-one consecutive patients who were admitted to our surgical department with left iliac pain and endoscopical or radiological diagnosis of DD were enrolled in this trial.

The usefulness of preoperative ultrasonographic identification of nonrecurrent inferior laryngeal nerve in neck surgery.

Backgrounds And Aims: Nonrecurrent inferior laryngeal nerve (ILN) represents a risk factor for injury during neck surgery. It is associated to arterial abnormalities (absence of the brachiocephalic trunk and arteria lusoria) that can be identified by ultrasonography. The aim of the study was to verify the usefulness of preoperative ultrasonography in the research of nonrecurrent ILN by the means of identification of arterial abnormalities and the impact on ILN morbidity.

The role of unilateral adrenalectomy in ACTH-independent macronodular adrenal hyperplasia (AIMAH).

Background: ACTH-independent macronodular adrenal hyperplasia (AIMAH) is a rare cause of Cushing's syndrome. Bilateral adrenalectomy is considered the treatment of choice, with subsequent lifetime steroid replacement, but unilateral adrenalectomy has been recently proposed to reduce the secreting tissue. This prospective study was designed to evaluate the long-term results of unilateral adrenalectomy in AIMAH concerning the main laboratory and clinical abnormalities and the patient's quality of life.

Risk factors of endoleak following endovascular repair of abdominal aortic aneurysm. A multicentric retrospective study.

Endoleak (EL) represents the most common complication following endovascular abdominal aortic aneurysm repair (EVAR). Unfortunately, the long-term results of EVAR and its durability have been questioned, and EL are variably associated with a risk of late failure. The aim of this retrospective study was to identify risk factors for this complication of aneurysm-endograft complex in patients who underwent EVAR.

Endoscopic dilation of benign esophageal strictures in a surgical unit: a report on 95 cases.

Ninety-five patients were treated by endoscopic dilation without fluoroscopic guidance between 1997 and 2005 for benign esophageal strictures. The etiologies were: anastomotic (38), postfundoplication (13), caustic (14), peptic (11), radiation-induced (10) and others (9). The strictures were classified at every session on a 0 to 4 scale on the basis of the diet and the luminal diameter.

[Ruptured aneurysms of the abdominal aorta: from the First Aid to the Operating Room. Changing concepts].

Worldwide literature review from PubMed indicate that progress has been made in first aid assistance, diagnosis and treatment of ruptured abdominal aortic aneurysms, which led to a reduced operative mortality. Nevertheless, ruptured aneurysms may present atipically in about half of the cases, thus leading to an initially uncorrect diagnosis up to 25% of cases. Mean survival interval from onset of symptoms and death is 10-14 hours, thus indicating that time exists to consider the new imaging techniques in 80% of patients, particularly the TC multislice.
