To evaluate the results of carotid endarterectomy (CEA) in patients with a concomitant asymptomatic intracranial aneurysm discovered at preoperative diagnostic imaging.From January 2000 to December 2020, 75 consecutive patients admitted for surgical treatment of asymptomatic more than 70% (North American Symptomatic Carotid Endarterectomy Trial) carotid artery stenosis presented at preoperative computed tomography angiography (CTA) with a concomitant, unruptured intracranial aneurysm (UIA). Aneurysm diameter was 5 mm or less in 25 patients (group A), from 6 to 9 mm in 38 patients (group B), and 10 or more mm in 12 patients (group C). Sixty UIAs (80%) were treated before performing CEA, 10 in group A (40%), 38 (100%) in group B, and 12 (100%) in group C. Twenty-five UIAs (42%) were subjected to surgical clipping and 35 (58%) to coiling. The mean time intervals were 48 days (range, 20-55 days) between clipping and CEA, and 8 days (range, 4 -13 days) between coiling and CEA. CEA was standard and performed through eversion of the internal carotid artery in 36 patients (48%) and through longitudinal arteriotomy with systematic patch closure in 39 patients (52%). The primary end points of the study were mortality and morbidity related to each of the two treatments, including any complication occurring during the time interval between the two procedures or within 30 days after the last procedure. Secondary end points were mid-term survival and freedom from ischemic or hemorrhagic stroke and carotid restenosis.One patient died during the 30 days after the clipping of a 11-mm diameter UIA of the basilar artery. No other death or complication was observed after CEA and treatment of the UIA, or during the time interval between the two procedures. During a median follow-up of 26 months (interquartile range, 18-30 months), no late stroke and no carotid restenosis were observed. At 22, 27, 29 and 31 months after CEA, four patients in group A underwent surgical clipping of an enlarging intracranial aneurysm that had not been treated initially owing to its small diameter. The cumulative survival rate at 30 months by Kaplan-Meier plots was 83 ± 5%.Concomitant asymptomatic carotid artery stenosis and UIA is a rare entity. Our study suggests that in this setting, prior treatment of the UIA followed by CEA is safe.

Reducing fluoroscopy times and iodine contrast administration during endovascular repair (EVAR) of infrarenal aortic aneurysms remains a challenge. The purpose of this study is to evaluate the preliminary results of a fully ultrasound-assisted EVAR without iodine contrast administration.Twenty-seven consecutive patients underwent an elective intravascular ultrasound (IVUS)-assisted EVAR with final contrast-enhanced ultrasound (CEUS) control of correct aneurysm exclusion. In no case intraprocedural injection of iodine contrast medium was performed. The primary study's end points were the overall duration of the procedure, duration of fluoroscopy, cumulative radiation dose, the length of intraoperative CEUS control, and the comparison of findings between intraoperative CEUS and computed tomography (CT) scan at 1 month.Mean duration of the procedure was 130 ± 35 min. Overall duration of fluoroscopy was 22 ± 18 min. Mean radiation dose was 66 mGy (range 24-82). The mean length of CEUS final control was 8 ± 2 min. No type I or type III endoleak was detected either at CEUS or at angio-CT scan at 1 month from EVAR. CEUS revealed a type II endoleak in 6 patients (22%), compared to 9 type II endoleaks (33%) detected at angio-CT scan 1 month after the procedure (P = 0.5).Fully ultrasound (IVUS and CEUS)-assisted EVAR is safe, feasible, and reliable, completely eliminating the need for iodine contrast medium and reducing the radiation exposure for both patients and surgeons.

Background Carotid body tumor (CBT) is a slow-growing tumor arising from the carotid body, a chemoceptor organ lying behind the carotid artery bifurcation. Although rarely, metastases can occur distally through the hematogenous route and through the lymphatic route.to the cervical lymphnodes. The purpose of this study was to assess whether lymphnodes’ resection should systematically be associated with the primary resection of a CBT. Methods A retrospective analysis of 82 patients, 52 women of a mean age of 42 years undergoing resection of 88 CBT from 1994 to 2019. CBT were divided into 2 groups. Tumors in group A (n = 23, 26%) were treated by resection of the mass followed by a selective latero-cervical lymphadenectomy; tumors in group B (n = 65, 74%) underwent isolated resection of the mass. The study's primary endpoints were postoperative stroke/mortality rate, disease-specific survival and rate of local and distant recurrence of the disease. Results Postoperative stroke-mortality rate was nil. One patient in group A (4.3%) presented a minor weakness of the contralateral arm, completely regressive within 12 h. One patient in group B (1.5%) died of liver and lung metastases 51 months after operation, no patient died of recurrent disease in group A (p = .62). No nodal recurrence was observed in group A, whereas one patient in group B (1.5%) presented nodal recurrence 39 months after primary tumor resection (p = .58) Conclusion Selective lymphadenectomy associated with CBT resection does not increase the overall long-term survival and cannot be considered mandatory. It may help to better define the stage of the disease and to plan eventual adjuvant treatments.

Background/Aim:With the increasing use of endovascular aneurysm repair (EVAR) and the availability of laparoscopic cholecystectomy (LC) for treating abdominal aortic aneurysms (AAA) and cholelithiasis, respectively, the association between these elective treatments is not yet well-defined. Thus, this study aimed to evaluate the results of elective and simultaneous EVAR and LC.Methods:Thirteen patients (mean age, 72 years) with concomitant large and asymptomatic AAA and asymptomatic cholelithiasis underwent simultaneous EVAR and LC.Results:Post-operative mortality was absent, and the morbidity rate was 7%. The mean total duration of the procedure was 142 min. The mean duration of fluoroscopy was 19 min, and the mean radiation dose was 65 mGy. The mean amount of iodinated contrast injected was 49 mL. The timing of oral fluid intake was 28 h (range, 24–48 h) and that of the oral low-fat diet was 53 h (range, 48–72 h). No patient presented with an aortic graft infection during the entire follow-up period (mean duration, 41 months). The mean length of post-operative hospital stay was 6 days (range, 5–8 days). Late survival was 85%, and the exclusion of AAA was 100%.Conclusion:Simultaneous EVAR and LC can be performed safely, allowing effective and durable treatment under both AAA and cholelithiasis conditions.

True aneurysms of the peri-pancreatic arcade (PDAA) have been attributed to increased collateral flow related to coeliac axis (CA) occlusion by a median arcuate ligament (MAL). Although PDAA exclusion is currently recommended, simultaneous CA release and the technique to be used are debated. The aim of this retrospective multicentre study was to compare the results of open surgical repair of true non-ruptured PDAA with release or CA bypass (group A) vs. coil embolisation of PDAA and CA stenting or laparoscopic release (group B).From January 1994 to February 2019, 57 consecutive patients (group A: 31 patients; group B: 26 patients), including 35 (61%) men (mean age 56 ± 11 years), were treated at three centres. Twenty-six patients (46%) presented with non-specific abdominal pain: 15 (48%) in group A and 11 (42%) in group B (p = .80).No patient died during the post-operative period. At 30 days, all PDAAs following open repair and embolisation had been treated successfully. In group A, all CAs treated by MAL release or bypass were patent. In group B, 2/12 CA stentings failed at48 hours, and all MAL released by laparoscopy were successful. Median length of hospital stay was significantly greater in group A than in group B (5 vs. 3 days; p = .001). In group A, all PDAAs remained excluded. In group B, three PDAA recanalisations following embolisation were treated successfully (two redo embolisations and one open surgical resection). At six years, Kaplan-Meier estimates of freedom for PDAA recanalisation were 100% in group A, and 88% ± 6% in group B (p = .082). No PDAA ruptured during follow up. In group A, all 37 CAs treated by MAL release were patent, and one aortohepatic bypass occluded. In group B, five CAs occluded: four after stenting and the other after laparoscopic MAL release with two redo stenting and three aortohepatic bypasses. Estimates of freedom from CA restenosis/occlusion were 95% ± 3% for MAL release or visceral bypass, and 60% ± 9% for CA stenting (p = .001). Two late restenoses following CA stenting were associated with PDAA recanalisation.Current data suggest that open and endovascular treatment of PDAA can be performed with excellent post-operative results in both groups. However, PDAA embolisation was associated with few midterm recanalisations and CA stenting with a significant number of early and midterm failures.

Background/aim Primary adrenal lymphoma (PAL) is rare and aggressive. The aim of this retrospective study was to compare the results of surgery and chemotherapy compared to chemotherapy alone for the treatment of this condition. Patients and methods Sixteen patients, 10 men and 6 women of a median age of 63 years (IQR=56-70.5 years), admitted for the treatment of PAL, were retrospectively reviewed. Six patients (37.5%) underwent surgical resection of the mass followed by CHOP (cyclophosphamide, doxorubicin, vincristine, bleomycin and prednisone) - based chemotherapy (Group A). Ten patients (62.5%) underwent chemotherapy alone, consisting of CHOP alone in one case and Rituximab-CHOP (R-CHOP) in 9 cases (Group B). As primary study endpoints of the study, overall survival (OS) and progression-free survival (PFS) were considered. Results At two years follow-up, OS was 50% in Group A and 60% in group B (p=0.69). The PFS was 50% in group A and 30% in group B (p=0.42). Conclusion PAL exhibits overall a dismal prognosis. Chemotherapy remains the most appropriate treatment, although unable to ensure long-term survival. Surgery combined with chemotherapy is ineffective in improving survival and may, at best, have a limited role in relieving the pain related to the local mass effect.

Purpose The double-staple technique, performed as either the standard procedure or after eversion of the rectal stump, is a well-established method of performing low colorectal anastomoses following the resection of rectal cancer. Eversion of the tumor-bearing ano-rectal stump was proposed to allow the linear stapler to be fired at a safe distance of clearance from the tumor. We conducted this study to compare the results of the standard versus the eversion-modified double-staple technique. Methods The subjects of this retrospective study were 753 consecutive patients who underwent low stapled colorectal anastomosis after resection of rectal cancer. The patients were divided into two groups according to the method of anastomosis used: Group A comprised 165 patients (22%) treated with the modified eversion technique and group B comprised 588 patients (78%) treated with the standard technique. The primary endpoints of the study were postoperative mortality, surgery-related morbidity, the number of sampled lymph nodes in the mesorectum, and late disease-related survival. Results Postoperative mortality was 1.2% in group A and 1.7% in group B (p = 0.66). Postoperative morbidity was 12% in group A and 11% in group B (p = 0.75). The mean number of sampled lymph nodes in the mesorectum was 23 (range 17–27) in group A and 24 (range 19–29) in group B (p = 0.06). The 5-year disease-related survival was 73% in group A and 74% in group B (p = 0.75). Conclusion The standard and eversion-modified double-staple techniques yield comparable results.

Background Penetrating aortic ulcer (PAU) is an atherosclerotic lesion penetrating the elastic lamina and extending into the media of the aorta. It may evolve into intramural hematoma, focal dissection, pseudoaneurysm and eventually rupture. The purpose of this study was to evaluate the effectiveness of a totally intravascular ultrasound (IVUS) - assisted endovascular exclusion of PAU. Methods Thirteen consecutive patients (median age of 66 years) underwent IVUS-assisted endovascular exclusion of PAU. The primary endpoints were fluoroscopy time, radiation dose and occurrence of type I primary endoleak. Secondary endpoints were postoperative mortality and morbidity, arterial access complications, postoperative length of stay in the hospital and occurrence of type II endoleaks. Results The median fluoroscopy time was 4 minutes [4-5]. The median radiation dose was 4.2 mGy [3.9-4.5]. A proximal and distal landing zone of at least 2cm could be obtained in all the patients. No patient presented a type I endoleak. No postoperative mortality, no morbidity or arterial access complication was observed. The median length of postoperative stay in the hospital was 2 days [2-3]. The median length of follow-up was 25 months [9.2-38.7].One late type II endoleak was observed (7.7 %), due to reflux from the intercostal arteries, without the need for additional treatment. Conclusion IVUS-assisted endovascular treatment of PAU allows durable exclusion of PAU with a short fluoroscopy time and no need for injection of contrast media. Further series are needed to confirm the results of this preliminary study.

Background/aim Thrombosis internal jugular vein (IJV) with cervical adenopathy, as first manifestation of gastric cancer is rare. We aimed to compare resection of the cervical mass followed by gastrectomy with gastrectomy alone. Patients and methods Nine patients presenting thrombosis of the IJV for gastric carcinoma were divided into two groups. Patients in group A (n=3) underwent anticoagulation treatment, gastrectomy and adjuvant treatment. Patients in group B (n=6) underwent resection of the cervical mass and internal jugular vein (radical neck dissection), and then gastrectomy and adjuvant treatment. Results Median survival was 15.3 months in group A (range=11-19 months) and 31.2 months in group B (range=7-44 months) (p=0.11). Late cervical recurrence/complications occurred in 2 patients in group A and none in group B (p=0.02). Conclusion Resection of thrombosed IJV and satellite lymph nodes, due to a primary gastric cancer may contribute to diagnosis of the disease, limit pulmonary embolic complications and improve quality of life.

Background/Aim: The purpose of this study was to evaluate the results of stapled closure of the pancreatic remnant after cold-knife section of the pancreatic isthmus and distal pancreatectomy for adenocarcinoma. Methods: A retrospective evaluation of 57 consecutive patients undergoing distal spleno-pancreatectomy for adenocarcinoma was performed. The pancreatic isthmus was systematically straight-sectioned with a cold knife, and the remnant was stapled close without additional stitches or adjuncts. The study's main endpoints were postoperative mortality, the occurrence of a pancreatic fistula, the need for a re-operation, the postoperative length of stay in the hospital, the rate of re-admission, and late survival. Results: Postoperative mortality was absent. Seventeen patients (29.8%) presented a pancreatic fistula of grade A in seven cases (41.2%), grade B in eight cases (47.1%), and grade C in two cases (11.8%). Re-operation was required in the two patients (3.5%) with grade C fistula in order to drain an intra-abdominal abscess. The mean postoperative length of stay in the hospital was 15 days (range, 6–62 days). No patient required re-admission. Twenty-nine patients (50.8%) were alive and free from disease, respectively, 12 patients (21.1%) at 12 months, 13 patients (22.8%) at 60 months, and four patients (7.0%) at 120 months from the operation. The remaining patients died of metastatic disease 9–37 months from the operation. Lastly, disease-related mortality was 49.1%. Conclusion: Stapler closure of the pancreatic remnant allows good postoperative results, limiting the formation of pancreatic fistula to the lower limit of its overall reported incidence.
