Epidemiology, clinical features and diagnostic work-up of cystic neoplasms of the pancreas: Interim analysis of the prospective PANCY survey.

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 (1.1%) had non cystic neoplastic lesions. Forty percent (518/1295) had at least one 1st degree relative affected by a solid tumor of the digestive and extra-digestive organs. Symptoms/signs associated with the cystic lesion were present in 24.5% of the patients. The cysts were localized in the head of the pancreas in 38.5% of patients. Of the 2370 examinations (1.7 examinations per patient) which were carried out for the diagnosis, magnetic resonance imaging was performed as a single test in 48.4% of patients and in combination with endoscopic ultrasound in 27% of the cases. Of the 1370 patients having CPNs, 89.9% had an intraductal papillary mucinous neoplasm (IPMN) (70.1% a branch duct IPMN, 6.2% a mixed type IPMN and 4.6% a main duct IPMN), 12.7% had a serous cystadenoma, 2.8% a mucinous cystadenoma, 1.5% a non-functioning cystic neuroendocrine neoplasm, 0.7% a solid-pseudopapillary cystic neoplasm, 0.3% a cystic adenocarcinoma, and 1.2% an undetermined cystic neoplasm. Seventy-eight (5.7%) patients were operated upon after the initial work-up. CONCLUSIONS: This prospective study offers a reliable real-life picture of the diagnostic work-up CPN.

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. This retrospective study was a survey conducted in a large Italian North-Eastern area including three regions (Triveneto), over a 12-month period (January-December 2015). Patients' characteristics and surgical technique details were recorded, along with data on the prevalence of stenosis and its treatment. Patients with mid or low rectal resection and/or neoadjuvant chemo-radio therapy and/or diverting stoma were excluded. The study was promoted by the Italian Association of Hospital Surgeons (ACOI) and the Society of Surgeons of the Triveneto Region. Twenty-eight surgical units were enrolled in the survey, accounting for over 1400 patients studied. Fifty percent of the units performed laparoscopically > 70% of the colorectal resections and 7.5% of the procedures were emergent. Less than 60% of the units planned regular endoscopic follow-up after colorectal resection. Anastomotic stricture was recorded in 2% of the patients; 88% of the stenoses were diagnosed within 6 months from surgery. Only one anastomotic stricture required re-do surgery. The CANSAS study confirms that colorectal anastomotic stenosis is low-rate-but still present-complication. Treatment strategies vary according to surgeons' and endoscopists' preferences. Commonly endoscopic dilatation is preferred, but re-do surgery is required in some cases.

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. We present the case of a previously unreported bilateral adrenal hemorrhage occurring in a 59-year-old Caucasian male who was admitted to our surgical division with the diagnosis of a right retroperitoneal spontaneous hemorrhage. Imaging revealed a 10-cm ruptured right adrenal mass with no other abdominal lesions, endocrine screening results were normal, and a right adrenalectomy was performed. Pathology revealed a ruptured ACC. The postoperative period was uneventful and the patient was discharged. While recovering, 3 weeks after the operation, the patient showed the same symptoms on the contralateral side. Imaging once again revealed a retroperitoneal hemorrhage due to a 5-cm ruptured left adrenal mass. Endocrine screening showed a frank peripheral hypercortisolism and imaging showed a huge metastatic dissemination to the liver, lungs, and retroperitoneal space. An urgent left adrenalectomy was performed and pathology showed a metastatic ruptured ACC. The patient was placed in substitutive therapy but never recovered and died of penta lobar pneumonia on postoperative day 31. An extensive review of the current literature on the issue was performed. ACC is confirmed to be a lethal cancer. Rupture is the rarest clinical presentation and appears to be caused by the tumor's growth rate more than the tumor dimensions itself. The use of endocrine screening on such hemodynamically unstable patients is questionable.

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. Among these two-hundred patients, one-hundred-eleven (55.5%) underwent ERCP after MRCP. The retrospective study design consisted in the systematic revision of all images from MRCP and EUS/ERCP performed by two radiologist with a long experience in biliary imaging, an experienced endoscopist and a senior consultant in Hepatobiliopancreatic surgery. A false positive was defined an MRCP showing calculi with no findings at EUS/ERCP; a true positive was defined as a concordance between MRCP and EUS/ERCP findings; a false negative was defined as the absence of images suggesting calculi at MRCP with calculi localization/extraction at EUS/ERCP and a true negative was defined as a patient with no calculi at MRCP ad at least 6 mo of asymptomatic follow-up. Biliary tree dilatation was defined as a common bile duct diameter larger than 6 mm in a patient who had an in situ gallbladder. A third blinded radiologist who examined the MRCP and ERCP data reviewed misdiagnosed cases. Once obtained overall data on sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) we divided patients in two groups composed of those having concordant MRCP and EUS/ERCP (Group A, 72 patients) and those having discordant MRCP and EUS/ERCP (Group B, 20 patients). Dataset comparisons had been made by the Student's t-test and χ (2) when appropriate. RESULTS: Two-hundred patients (91 men, 109 women, mean age 67.6 years, and range 25-98 years) underwent MRCP. All patients attended regular follow-up for at least 6 mo. Morbidity and mortality related to MRCP were null. MRCP was the only exam performed in 89 patients because it did show only calculi into the gallbladder with no signs of the presence of calculi into the bile duct and symptoms resolved within a few days or after colecistectomy. The patients remained asymptomatic for at least 6 mo, and we assumed they were true negatives. One hundred eleven (53 men, 58 women, mean age 69 years, range 25-98 years) underwent ERCP following MRCP. We did not find any difference between the two groups in terms of race, age, and sex. The overall median interval between MRCP and ERCP was 9 d. In detecting biliary stones MRCP Sensitivity was 77.4%, Specificity 100% and Accuracy 80.5% with a PPV of 100% and NPV of 85%; EUS showed 95% sensitivity, 100% specificity, 95.5% accuracy with 100% PPV and 57.1% NPV. The association of EUS with ERCP performed at 100% in all the evaluated parameters. When comparing the two groups, we did not find any statistically significant difference regarding age, sex, and race. Similarly, we did not find any differences regarding the number of extracted stones: 116 stones in Group A (median 2, range 1 to 9) and 27 in Group B (median 2, range 1 to 4). When we compared the size of the extracted stones we found that the patients in Group B had significantly smaller stones: 14.16 ± 8.11 mm in Group A and 5.15 ± 2.09 mm in Group B; 95% confidence interval = 5.89-12.13, standard error = 1.577; P < 0.05. We also found that in Group B there was a significantly higher incidence of stones smaller than 5 mm: 36 in Group A and 18 in Group B, P < 0.05. CONCLUSION: Major finding of the present study is that choledocholithiasis is still under-diagnosed in MRCP. Smaller stones (< 5 mm diameter) are hardly visualized on MRCP.

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. MATERIAL AND METHODS: We reviewed 28 surgical patients with SH between January 2002 and December 2013. We evaluated the incidence of complications, recurrences, and the length of hospital stay with comorbidities, body mass index, clinical presentation, and operative techniques. RESULTS: The 28 patients included 10 males and 18 females, with a mean age of 67 years. Seven patients (26.9%) received emergency operations, and the remaining patients received elective operations. An "open-direct" operative approach was used in 16 cases and a laparoscopic approach in 12. The overall complication rate was 7.6% and the recurrence rate was 3.8% with a median follow-up of 3 years. The median hospital stay was 1 day (range, 1-7). Only the presence of local complications at diagnosis showed a significant impact on length of hospital stay. None of the considered variables had a significant impact on hernia recurrence. CONCLUSION: No differences were noted among the operative techniques, wound infections, complications rate, and length of hospital stay. Laparoscopy seems to cause more early postoperative pain that reverses in about 2 weeks.

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). Since LAPC and BRPC have been recognized as a particular form of PC neoadjuvant therapy (NT) has increasingly became a valid treatment option. The aim of NT is to reach local control of disease but, also, it is recognized to convert about 40% of LAPC patients to R0 resectability, thus providing a significant improvement of prognosis for responding patients. Once R0 resection is achieved, survival is comparable to that of early stage PCs treated by upfront surgery. Thus it is crucial to look for a proper patient selection. Neoadjuvant strategies are multiples and include neoadjuvant chemotherapy (nCT), and the association of nCT with radiotherapy (nCRT) given as either a combination of a radio sensitizing drug as gemcitabine or capecitabine or and concomitant irradiation or as upfront nCT followed by nRT associated to a radio sensitizing drug. This latter seem to be most promising as it may select patients who do not go on disease progression during initial treatment and seem to have a better prognosis. The clinical relevance of nCRT may be enhanced by the application of higher active protocols as FOLFIRINOX.

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. The treatment of choice is complete excision with negative margins to avoid local recurrence. Their tendency to locally invade the surrounding tissues requires sometimes extended resections. Laparoscopic cholecystectomy can be a questionable choice in this setting; however, the procedures can be performed safely in most cases, although complicated. We report the case of a hemorrhagic cystic lymphangioma of the gallbladder mimicking a subhepatic abscess and operated in emergency with laparoscopic approach.

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. PATIENTS AND METHODS: In this retrospective study, 35 patients who underwent MRE and then surgery for CD were enrolled from 2006 to 2010. MRE findings were compared to intraoperative findings. Histology of operative specimens, systemic inflammatory parameters, and fecal lactoferrin were also evaluated. Cohen's κ agreement test, sensitivity and sensibility, uni-/multivariate logistic regression, and non-parametric statistics were performed. RESULTS: MRE identified bowel stenosis with a sensitivity of 0.95 (95% CI 0.76-0.99) and a specificity of 0.72 (95% CI 0.39-0.92). The concordance of MRE findings with intraoperative findings was high [Cohen's κ = 0.72 (0.16)]. Abscesses were detected at MRE with a sensitivity of 0.92 (95% CI 0.62-0.99) and a specificity of 0.90 (95% CI 0.69-0.98) with a Cohen's κ = 0.82 (0.16). The grade of proximal bowel dilatation resulted to be a significant predictor of the possibility of using strictureplasty instead of/associated to bowel resection either at univariate or at multivariate analysis. CONCLUSION: Our study confirmed that MRE findings correlate significantly with disease activity. Detailed information about abscess could suggest percutaneous drainage that could ease the following surgery or avoid emergency laparotomy. Proximal bowel dilatation can suggest the possibility to perform bowel sparing surgery such as strictureplasty.

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. Even in such a multifaceted context, evidence has been provided that surveillance of dysplasia is effective in reducing both CRC mortality and morbidity. This manuscript focuses on current issues concerning the histology assessment of the IBD-associated dysplastic lesions.

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. If low-grade dysplasia is detected, the 9-fold increased risk of developing CRC reported in the most recent meta-analysis could reasonably be viewed as justification for colectomy even if some follow-up studies have shown a lower rate of CRC. A reasonable compromise could be to continue surveillance with extensive biopsy sampling at shorter (perhaps 3-6 month) intervals. If high grade dysplasia is present, the decision is easier, because the risk of concomitant CRC may be as high as one third, assuming that the biopsies were indeed obtained from flat mucosa and not from an adenoma. Total proctocolectomy with ileal pouch anal anastomosis (IPAA) has become the most commonly performed procedure for patients with ulcerative colitis requiring elective surgery for dysplasia. Nevertheless, a recent systematic review alerted that the risk of dysplasia in anal transition zone and rectal cuff in patients undergone to restorative proctocolectomy was remarkable, mainly in patients operated on for dysplasia or colorectal cancer.

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. In UC carcinogenesis the early events are represented by DNA methylation that produce an inhibition of onco-suppressor genes, mutation of p53, aneuploidy and microsatellite instability. Hypermethylation of tumor suppressors and DNA mismatch repair gene promoter regions, is an epigenetic mechanism of gene silencing that contributes to tumorigenesis and might represent the first step in inflammatory carcinogenesis. P53 is frequently mutated in the early stages of UC-associated cancer, in 33-67% of patients with dysplasia and in 83-95% of UC related cancer patients. Moreover, aneuploidy is an independent risk factor for forthcoming carcinogenesis in UC Finally, the inconsistency between the high cumulative rate of dysplasia in UC and the relatively lower incidence of invasive cancer raises the question about the mechanisms of immunosurveillance that may prevent malignant progression of neoplasm in the colon in most cases. Co-stimulatory molecule CD80 up-regulation in colonic mucosa in UC dysplasia may be one of these mechanism.

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. A transanal endoscopic microsurgery (TEM) device and endoscopic and laparoscopic instruments were used. RESULTS: The findings demonstrated that an ileorectal bypass through a transanal access is feasible. The principal steps of a standardized transanal procedure are as follows: confirm a rectal perforation above the peritoneal reflection, perform peritoneoscopy using a standard gastroscope, grasp the small bowel with retrieval forceps and pull it through the rectal hole, suture the ileum and the rectum together using a TEM device, open the ileal loop, and perform endoscopic exploration. Satisfactory anastomosis and no signs of procedure-related complications were confirmed by a post procedure laparotomy. CONCLUSIONS: Ileorectal bypass through a transanal access is technically feasible in a porcine model, and although still at an experimental stage, it could become a surgical option for treating some types of colonic strictures.

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. All patients with histology of IM or low-grade dysplasia (LGD) treated with diode laser therapy for BE and followed for at least 24 months were included in the study. Treatment sessions were carried out every 3 months and bioptic follow-up examinations were done yearly. Patients without antireflux surgery received proton pump inhibitors. A total of 20 patients with IM, four of them with LGD, were treated with 161 laser sessions (in mean eight per patient) without complications. Complete, sustained endoscopic and histologic remission was obtained in 13 patients (11/12 with BE ≤ 3 cm and 2/8 with BE >3 cm, p < 0.01) and a mean of 83 ± 27% of the metaplasic tissue was removed in all the patients. All four cases of LGD healed to squamous tissue. No buried metaplasia, recurrences, or disease progressions were reported after a mean follow-up of 6 years and 2 months. Diode laser ablation is a safe and effective method in most cases of short BE, while it is less effective in the long form, requiring a large number of sessions. Long-term results show that the risk of recurrence and of buried intestinal metaplasia underneath neosquamous epithelium is negligible.

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. RESULTS: Video-assisted and sternotomic parathyroid explorations achieved biochemical cure in all cases; following conventional transcervical mediastinal exploration, a persistent hyperparathyroidism occurred in 11.8% of patients, who were subsequently cured by sternotomic approach. No complications occurred after video-assisted parathyroidectomy, while an overall morbidity rate of 50% and 10% was found after sternotomic and conventional cervicotomic approaches. Postoperative pain and hospital stay were significantly increased following sternotomy; patient's subjective cosmetic satisfaction was significantly higher after video-assisted and conventional cervicotomic approaches. CONCLUSIONS: Conventional cervicotomic parathyroidectomy may achieve satisfactory results, especially for upper mediastinal glands. Sternotomic approaches are effective, but should be limited because of invasiveness and increased morbidity. In case of deep and lower hyperfunctioning mediastinal parathyroids, video-assisted approaches represent a less invasive, effective, and safe alternative and might be the technique of choice.

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 complete series of patients who had major colorectal surgery from 1999 until 2006 were reviewed for overt DVT episodes. Furthermore, 60 consecutive patients who were admitted for surgery for IBD were prospectively enrolled in the 2004-2006 period. Each patient underwent venous color Doppler ultrasound scan at admission and at discharge. Demographic data, disease activity, and clotting parameters were collected. Data were analyzed with Spearman's correlation test, multiple regression, and receiver operating characteristics (ROC) curves analysis. RESULTS: The rate of DVT in UC patients was significantly higher than in colorectal cancer patients (p = 0.009), and the odds ratio (OR) for postoperative DVT in UC patients was 7.4 (95% CI 1.4-44.4; p = 0.017). Female gender, UC diagnosis, active rectal bleeding, aPTT value, aCL IgM, abeta2 IgM, and pANCA levels significantly correlated with postoperative DVT. At multivariate analysis only aCL IgM levels were found to be independently associated with postoperative DVT (p = 0.05). CONCLUSIONS: In conclusion, our study showed that prophylactic therapy with 4,000 IU/day LMWH was not completely effective for the prevention of postoperative DVT in patients with CD, and even less so in those with UC. In these patients, a more tailored prophylactic therapy should be considered, and further randomized controlled trials testing the effectiveness of different prophylactic protocols would be advisable. Furthermore, aCL IgM serum levels might be helpful in identifying IBD patients who are at higher risk of postoperative DVT.

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. Seventy-seven had a hostile neck anatomy due to previous oncologic surgery or neck irradiation, restenoses after CEA, high carotid bifurcation, or bull-like and inextensible neck. A case-control matched-pair cohort study considered sex, age (5-year intervals), and year of operation. Regional anesthesia was used for all operations for atherosclerotic stenosis >or=70%, conforming to the European Carotid Surgery Trial (ECST) in symptomatic and asymptomatic patients, at a single center and by one surgeon or under his direct supervision. RESULTS: The hostile neck patients and the control group were matched for age, sex, carotid-related symptoms, degree of stenoses, and main risk factors for cardiovascular diseases. Intraoperative variables were substantially equivalent in the two groups; however, procedure length and clamping time were, respectively, about 22 minutes (P = .0001) and 7 minutes longer (P = .01) in the hostile neck group. Rates of postoperative mortality and neurologic events were equivalent. Peripheral nerve lesions were multiple and significantly more frequent in the hostile neck patients (21% with >or=1 cranial nerve lesion vs 7% of controls, P = .03), yet all were transient and limited to a few months. The subgroups of patients with hostile neck, restenoses, and bull-like inextensible necks required the longest operative and clamping time, and those with bull-like and high bifurcation had the most frequent cranial nerve dysfunctions. At the respective follow-up of 47 and 45 months, survival curves (P = .48) and the incidence of restenoses and fatal and nonfatal strokes were similar (5 and 4, respectively). CONCLUSIONS: Hostile necks led to more complex CEA procedures but without substantial consequences in early and late morbidity and mortality. Most patients with hostile neck can undergo CEA at low risk, with the benefit of effective long-lasting stroke prevention similar to standard patients. In our opinion, the more frequent but temporary cranial nerve dysfunctions that occur are not sufficient to consider hostile neck patients noneligible for CEA.

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. Three weeks later, a massive haemorrhage due to rupture of an acute pseudoaneurysm was successfully treated with an endoluminal covered stent. This occluded two weeks later without important signs of bowel ischemia. The covered-stent placement allowed obtaining primary hemostasis and bowel perfusion preservation in spite of early occlusion. The patient did well after chemotherapy for one year and presented local recurrence at 16 months. Endovascular treatment of acute haemorrhage in presence of an intra-abdominal sepsis is feasible and useful following pancreatic surgery.

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. Disease severity was assessed with Hinchey scale. Twenty-five of the patients underwent colonic resection, while 46 were treated with medical therapy alone. After a median follow-up of 47 (3-102) months from the time of their first hospital admission, the patients responded to the questions of the Cleveland Global Quality of Life (CGQL) questionnaire and to a symptoms questionnaire during a telephone interview. Admittance and surgical procedures for DD were also investigated, and surgery- and symptoms-free survival rates were calculated. Nonparametric tests and survival analysis were used. RESULTS: The CGQL total scores and symptom frequency rate were found to be similar in the two groups (resection vs nonresection). Only current quality of health item was significantly worse in patients who had undergone colonic resection (p = 0.05). No difference was found in the rate and in the timing of surgical procedures and hospital admitting for DD in the two groups. In particular, the nine patients classified as Hinchey 1 who underwent surgery reported the same quality of life, symptoms frequency, operation, and hospital admitting rate as those who had been admitted with the same disease class but who received medical treatment only. CONCLUSIONS: Our results indicate that there does not seem to be any long-term advantage to colonic resection which should be considered only in patients presenting complicated DD.
