ABSTRACT

OBJECTIVES: The management of patients with recurrent neck cancer invading the carotid artery is controversial. The aim of this study was to evaluate the overall survival and healthy survival years (QALY) as well as the patency of carotid revascularization after enbloc tumor resection followed by complementary radiotherapy. METHODS: From 2000 to 2016, 42 consecutive patients with recurrent neck cancer invading the carotid artery underwent resection of the tumor associated with reconstruction of the carotid artery with a PTFE prosthesis (n=31) or with a saphenous vein graft (n=11). In 11 cases, resection was associated with musculocutaneous flap coverage. The primary tumor was a squamous cell carcinoma of the larynx (20 patients) or of the pharynx (9 patients), undifferentiated carcinoma of unknown origin (10 patients) and anaplastic thyroid carcinoma (3 patients). All patients had postoperative radiotherapy (50-70Gy) supplemented in 16 of them by chemotherapy. Nine patients had metastatic dissemination at the time of reoperation with a recurrent tumor ulcerated to the skin in 5 of them. RESULTS: The combined 30-day mortality and stroke rate was nil. Postoperative morbidity included dysphagia (n=8), vocal cord paralysis (n=6), late wound healing delay (n=2), transient mandibular claudication (n=1) and partial necrosis of the musculocutaneous flap (n=1). No infection and no thrombosis of the bypass were observed during follow-up [median: 31 months, range: 8-167 months]. Twenty-one patients (50%) died from the consequences of the spread of cancer, which had become metastatic, but without local recurrence. The 5-year survival rate was 50.9±8.3%. The median healthy survival year (QALY) was 3.38 [95% CI: 1.70-4.54] with a significant difference between patients without metastasis at the time of reoperation [n=33; QALY=4.02] and those with metastases [n=9; QALY=0.43; P=0.005]. Healthy life expectancy was also significantly longer in patients with laryngeal cancer [n=20, QALY=4.95] compared to patients with other types of tumors [n=22, QALY=1.67; P=0.032]. CONCLUSION: In the absence of metastases, enbloc resection of recurrent neck cancers invading the carotid artery improves the duration and quality of patient survival.

ABSTRACT

BACKGROUND: The extension of indications for procedures in a Day Surgery (DS) setting has led to changes in the anesthetic and surgical treatment of Inguinal Hernias (IH). According to the recommendations of the European Hernia Society, the treatment of IH in DS units should be performed under Monitored Anesthesia Care (MAC). PATIENTS AND METHODS: 960 patients underwent IH repairs over a period of 24 months. The patients were randomly divided into two groups: R (remifentanil) and F (fentanyl); the group F was considered as a control group. The exclusion criteria in both group were: morbid obesity (BMI>40 or BMI>35 in association with high blood pressure or diabetes); coagulopathy; OSAS (obstructive sleep apnea syndrome) with AHI >10; cardiovascular, respiratory, renal, hepatic or metabolic disease; history of substances abuse; GERD-related esophagitis (gastro-esophageal reflux disease); chronic analgesic use; allergy to local anesthetic and ASA>III. Patients reported their level of pain on a verbal numeric scale (VNS), with scores ranging from 0 to 10. For each patient systolic and diastolic blood pressure (SBP and DBP), mean arterial pressure (MAP), heart rate (HR) and peripheral oxygen saturation (SpO2) were recorded. The results are presented as the mean value ± standard deviations; statistical analysis was performed using Student's t-test. RESULTS: Amongst the 960 procedures, complications or side effects related to the anesthetic techniques didn't occur; no procedure-related complications requiring mechanical ventilation support were reported. Our research focused on evaluating remifentanil effectiveness in pain control and its impact on hemodynamic stability and respiratory function. There was a significant difference between the two groups with regard to the VNS. CONCLUSIONS: Remifentanil, is an excellent drug for pain control during intra-operative procedures, that allows an optimal hemodynamic stability for IH repairs in a DS setting, due to its pharmacokinetic and pharmacodynamic properties and few adverse effects.

ABSTRACT

OBJECTIVE: The aim of this randomized study is to evaluate the real benefits of the FOCUS Harmonic Scalpel in total thyroidectomies compared with conventional ligation, regarding operative time, postoperative blood loss, length of stay and complications. Furthermore, as never seen in other studies, we studied the effects of using the FOCUS during thyroidectomy analyzing the vocal production of patients before and after surgery. PATIENTS AND METHODS: We enrolled 361 patients who underwent total thyroidectomy from 2008 to 2014. It was a randomized clinical trial in which all the surgical procedures were performed by the same surgeon. Patients were randomized into two groups according to the haemostatic technique: 187 patients were included in a "conventional" group (C) in whom dissection and haemostasis were performed using conventional materials (Vicryl, stitches, V titanium hemostatic clips and monopolar or bipolar electrocautery); 174 patients were included in a group in which the FOCUS was used (F group). RESULTS: Our data show that the FOCUS allows a one-third time-saving vs. classic haemostasis. Moreover, the use of the FOCUS would allow reduced traction and reduced manipulation of the thyroid during surgery. Our data demonstrate that the rate of complications in the Focus group might not be significantly reduced. In our series, we noticed that the quantitative acoustic assessment of voice quality show important alterations in several parameters (Shim, Jitt, sPPQ, sAPQ studied with the Multi Dimensional Voice Program evaluation) between the C group and F group. CONCLUSIONS: The FOCUS Harmonic Scalpel reduces the operative time, post-operative blood loss and length of hospital stay in thyroidectomy. Besides, important vocal alterations after thyroidectomy seem more severe using the conventional technique instead of FOCUS.

ABSTRACT

OBJECTIVES: To evaluate the potential benefit of systematic preoperative coronary-artery angiography followed by selective coronary-artery revascularization on the incidence of myocardial infarction (MI) in patients undergoing carotid endarterectomy (CEA) without a previous history of coronary artery disease (CAD). METHODS: We randomised 426 patients who were candidates for CEA, with no history of CAD, a normal electrocardiogram (ECG), and a normal cardiac ultrasound. In group A (n = 216) all patients underwent coronary angiography before CEA. In group B (n = 210) CEA was performed without coronary angiography. Patients were not blinded for relevant assessments during follow-up. Primary end-point was the occurrence of MI at 3.5 years. The secondary end-point was the overall survival rate. Median length of follow-up was 6.2 years. RESULTS: In group A, coronary angiography revealed significant coronary artery stenosis in 68 patients (31.5%). Among them, 66 underwent percutaneous Intervention (PCI) prior to CEA and 2 received combined CEA and coronary-artery bypass grafting (CABG). Postoperatively, no MI was observed in group A, whereas 6 MI occurred in group B, one of which was fatal (p = .01). During the study period, 3 MI occurred in group A (1.4%) and 33 were observed in group B (15.7%), 6 of which were fatal. The Cox model demonstrated a reduced risk of MI for patients in group A receiving coronary angiography (HR,.078; 95% CI, 0.024-0.256; p < .001). In addition, patients with diabetes and patients <70 years presented with an increased risk of MI. Survival analysis at 6 years by Kaplan-Meier estimates was 95.6 ± 3.2% in Group A and 89.7 ± 3.7% in group B (Log Rank = 6.54, p = .01). CONCLUSIONS: In asymptomatic coronary-artery patients, systematic coronary angiography prior to CEA followed by selective PCI or CABG significantly reduces the incidence of late MI and increases long-term survival.

ABSTRACT

BACKGROUND: When performing low anterior resection for rectal cancer with the double staple technique, -closing the rectum with a linear stapler in the abdomen can be challenging, especially when dealing with a narrow pelvis. For such instances we proposed to modify this technique by pulling the rectal stump through the anus, doing an extra-anal resection of the tumor and linear suture of the rectal stump, before performing a standard, stapled colorectal anastomosis. The purpose of this study was to assess the adequacy of this modification of the double staple technique. METHODS: Retrospective review of 108 patients undergoing a stapled, low colorectal or coloanal anastomosis, after -eversion, extra-anal resection of the tumor and linear closure of the rectal stump for colorectal cancer, from January 1990 to December 2012. RESULTS: Operative mortality was 0.9%. Fourteen patients (13%) presented early, surgery-related complications -consisting of 7 anastomotic leaks, 5 wound infections, 1 ureteral lesion, and 1 peristomal abscess. Late complications related to surgery included 5 incisional hernias (4.6%), 4 anastomotic strictures (3.7%), 4 neurogenic bladders (3.7%) and 2 fecal incontinences (1.8%). The incidence of local disease recurrence was 10%. CONCLUSIONS: Surgical and oncological results validate the proposed modification of the double staple technique, when facing difficulties in suturing the rectum from the abdomen.

ABSTRACT

This review considers the role of the different revascularization strategies in patients with chronic limb ischemia (CLI) and reveals that clinical evidence guiding therapeutic decision-making in CLI is poor and only careful basic recommendations can be made. For diffuse aortoiliac disease with occlusion of the aorta, aortobifemoral bypass remains the best option if the patient is fit for open surgery. Unilateral iliac occlusion should be treated by primary stenting, but an iliofemoral bypass may be the best option when the disease extends down to the common and deep femoral arteries. For infrainguinal revascularisation, bypass using the saphenous vein remains the best option for patients with occlusion of the superficial femoral artery >25 cm and for patients with multiple occlusions of the infrapopliteal arteries. In the absence of leg veins, arm veins should be used. Prosthetic grafts are the last option. Endovascular techniques are recommended in patients with short arterial lesions and limited life expectancy <2 years. Finally some patients with CLI are best treated by primary amputation. In conclusion, this review demonstrates that neither an endo- first nor a bypass-first attitude is appropriate in patients with CLI and suggests that these patients should be cared for by specialists in a multidisciplinary center in order to preserve their life and limbs, to conduct clinical trials and to control costs.

ABSTRACT

Diabetic foot ulceration (DFU) is among the most frequent complications of diabetes. Neuropathy and ischaemia are the initiating factors and infection is mostly a consequence. We have shown in this review that any DFU should be considered to have vascular impairment. DFU will generally heal if the toe pressure is >55 mmHg and a transcutaneous oxygen pressure (TcPO2) <30 mmHg has been considered to predict that a diabetic ulcer may not heal. The decision to intervene is complex and made according to the symptoms and clinical findings. If both an endovascular and a bypass procedure are possible with an equal outcome to be expected, endovascular treatments should be preferred. Primary and secondary mid-term patency rates are better after bypass, but there is no difference in limb salvage. Bedridden patients with poor life expectancy and a non-revascularisable leg are indications for performing a major amputation. A deep infection is the immediate cause of amputation in 25% to 50% of diabetic patients. Patients with uncontrolled abscess, bone or joint involvement, gangrene, or necrotising fasciitis have a "foot-at risk" and need prompt surgical intervention with debridement and revascularisation. As demonstrated in this review, foot ulcer in diabetic is associated with high mortality and morbidity. Early referral, non-invasive vascular testing, imaging and intervention are crucial to improve DFU healing and to prevent amputation. Diabetics are eight to twenty-four times more likely than non-diabetics to have a lower limb amputation and it has been suggested that a large part of those amputations could be avoided by an early diagnosis and a multidisciplinary approach.

ABSTRACT

Mucoepidermoid carcinoma (MEC) of the skin is an extremely rare neoplasm but is common in the major and minor salivary glands accounting of approximately 30% of all malignant tumors arising from these glands. Cutaneous involvement should be carefully assessed to exclude the possibility of metastases from distant sites. We report an 81 year-old man presenting a primary cutaneous mucoepidermoid carcinoma infiltrating his left parotid gland. Excision of the affected skin and a total parotidectomy with supraomohyoid neck dissection (level I-III) was performed followed by radiotherapy. No relapse after 2 years follow up has been observed. Since the primary cutaneous mucoepidermoid carcinoma is an aggressive neoplasm that frequently develops metastases it is important to distinguish it from primary MEC originating from the salivary glands for better management and suitable therapeutic decisions.

ABSTRACT

Angioleiomyoma (AL) is a benign neoplasia originating from smooth muscle and very uncommon in the oral cavity. The most frequent subtype in the oral cavity is the vascular one. AL usually occurs in the extremities: only around 12% are found in other areas such as head and neck. It presents as an asymptomatic, slow growing nodule lodging in the palate, tongue or lips. The diagnosis is essentially by histological exam and special specific stains are helpful to confirm the origin and to distinguish it from other tumors. We present a case of AL found in unusual site: attached to the submandibular region in a deep-seated space.

ABSTRACT

OBJECTIVE: To evaluate the usefulness of systematic coronary angiography followed, if needed, by coronary artery angioplasty (percutaneous coronary intervention (PCI)) on the incidence of cardiac ischaemic events after carotid endarterectomy (CEA) in patients without evidence of coronary artery disease (CAD). MATERIALS AND METHODS: From January 2005 to December 2008, 426 patients, candidates for CEA, with no history of CAD and with normal cardiac ultrasound and electrocardiography (ECG), were randomised into two groups. In group A (n=216) all the patients had coronary angiography performed before CEA. In group B, all the patients had CEA without previous coronary angiography. In group A, 66 patients presenting significant coronary artery lesions at angiography received PCI before CEA. They subsequently underwent surgery under aspirin (100 mg day(-1)) and clopidogrel (75 mg day(-1)). CEA was performed within a median delay of 4 days after PCI (range: 1-8 days). Risk factors, indications for CEA and surgical techniques were comparable in both groups (p>0.05). The primary combined endpoint of the study was the incidence of postoperative myocardial ischaemic events combined with the incidence of complications of coronary angiography. Secondary endpoints were death and stroke rates after CEA and incidence of cervical haematoma. RESULTS: Postoperative mortality was 0% in group A and 0.9% in group B (p=0.24). One postoperative stroke (0.5%) occurred in group A, and two (0.9%) in group B (p=0.62). No postoperative myocardial event was observed in group A, whereas nine ischaemic events were observed in group B, including one fatal myocardial infarction (p=0.01). Binary logistic regression analysis demonstrated that preoperative coronary angiography was the only independent variable that predicted the occurrence of postoperative coronary ischaemia after CEA. The odds ratio for coronary angiography (group A) indicated that when holding all other variables constant, a patient having preoperative coronary angiography before carotid surgery was 4 times less likely to have a cardiac ischaemic event after carotid surgery. No complications related to coronary angiography were observed and no cervical haematomas occurred in patients undergoing surgery under aspirin and clopidogrel in this study. CONCLUSIONS: Systematic preoperative coronary angiography, possibly followed by PCI, significantly reduces the incidence of postoperative myocardial events after CEA in patients without clinical evidence of CAD.

ABSTRACT

AIM: Until fenestrated endografts will become the standard treatment of pararenal aortic aneurysms, open surgical repair will currently be employed for the repair of this condition. Suprarenal aortic control and larger surgical dissection represent additional technical requirements for the treatment of pararenal aneurysms compared to those of open infrarenal aortic aneurysms, which may be followed by an increased operative mortality and morbidity rate. As this may be especially true when dealing with pararenal aneurysms in an elderly patients' population, we decided to retrospectively review our results of open pararenal aortic aneurysm repair in elderly patients, in order to compare them with those reported in the literature. METHODS: Twenty-one patients over 75 years of age were operated on for pararenal aortic aneurysms in a ten-year period. Exposure of the aorta was obtained by means of a retroperitoneal access, through a left flank incision on the eleventh rib. When dealing with interrenal aortic aneurysm the left renal artery was revascularized with a retrograde bypass arising from the aortic graft, proximally bevelled on the ostium of the right renal artery. RESULTS: Two patients died of acute intestinal ischemia, yielding a postoperative mortality of 9.5%. Nonfatal complications included 2 pleural effusions, a transitory rise in postoperative serum creatinine levels in 3 cases, and one retroperitoneal hematoma. Mean renal ischemia time was 23 min, whereas mean visceral ischemia time was 19 min. Mean inhospital stay was 11 days. CONCLUSION: Pararenal aortic aneurysms in the elderly can be surgically repaired with results that are similar to those obtained in younger patients.

ABSTRACT

Due to the rarity of the condition, large and prospective series defining the optimal method of digestive arteries revascularization, for the treatment of chronic intestinal ischemia, are lacking. The aim of this consecutive sample clinical study was to test the hypothesis that flexible application of different revascularization methods, according to individual cases, will yield the best results in the management of chronic intestinal ischemia. Eleven patients, of a mean age of 56 years, underwent revascularization of 11 digestive arteries for symptomatic chronic mesenteric occlusive disease. Eleven superior mesenteric arteries and one celiac axis were revascularized. The revascularization techniques included retrograde bypass grafting in 7 cases, antegrade bypass grafting in 2, percutaneous arterial angioplasty in 1, and arterial reimplantation in one case. The donor axis for either reimplantation or bypass grafting was the infrarenal aorta in 4 cases, an infrarenal Dacron graft in 4, and the celiac aorta in one case. Grafting materials included 5 polytetrafluoroethylene (PTFE) and 3 Dacron grafts. Concomitant procedures included 3 aorto-ilio-femoral grafts and one renal artery revascularization. Mean follow-up duration was 31 months. There was no operative mortality. Cumulative survival rate was 88.9% at 36 months (SE 12.1%). Primary patency rate was 90% at 36 months (SE 11.6%). The symptom free rate was 90% at 36 months (SE 11.6%). Direct reimplantation, antegrade and retrograde bypass grafting, all allow good mid-term results: the choice of the optimal method depends on the anatomic and general patient's status. Associated infrarenal and renal arterial lesions can be safely treated in the same time of digestive revascularization. Angioplasty alone yields poor results and should be limited to patients at poor risk for surgery.

ABSTRACT

From January 1994 to July 2004, 323 patients underwent 348 revascularization of carotid bifurcation for atherosclerotic stenoses. Eighty eight patients (group A) were 75 year-old or older, whereas 235 (group B) were younger than 75 years. Postoperative mortality/neurologic morbidity rate was 1% in group A, and 1.4% in group B. At 5 years, patency and freedom from symptoms/stroke were, respectively, 91% and 92% in group A, and 89% and 91% in group B. None of these differences was statistically significant. In the same time period, 26 internal carotid arteries were revascularized in 24 patients, 75 or more aged, for a symptomatic kinking. Postoperative mortality/morbidity rate was absent, whereas, at 5 years, patency and freedom from symptoms/stroke were, respectively, 88% and 92%. Twelve vertebral arteries were revascularized in 12 patients, 75 or more aged, for invalidating symptoms of vertebrobasilar insufficiency. Postoperative mortality/neurologic morbidity rate was absent. In one case postoperative recurrence of symptoms occurred, despite a patent revascularization. Patency and freedom from symptoms/stroke were 84% and 75%, at 5 years. Revascularization of carotid and vertebral arteries in the elderly can be accomplished with good results, superposable to those of standard revascularization of carotid bifurcation in a younger patients' population.

ABSTRACT

METHODS: A series of 9 patients of a mean age of 48 years, operated on for compression of the ilio-femoral venous axis is reported. The cause of obstruction was external compression in 3 cases, a retroperitoneal sarcoma in 1 case, and an infrarenal aortic aneurysm in 2. Two patients presented with a Cockett's syndrome, 3 with a chronic ilio-femoral thrombosis, and one with a post-traumatic segmentary stenosis. Treatment consisted in a resection/Dacron grafting of 2 infrarenal aortic aneurysms, one femoro-caval bypass graft, 2 transpositions of the right common iliac artery in the left hypogastric artery for Cockett's syndrome, 3 Palma's operations for chronic thrombosis, and one internal jugular vein interposition for segmentary stenosis. RESULTS: There were no postoperative deaths and no early thromboses of venous reconstructions performed. All the patients were relieved of symptoms during the follow-up period, whose mean length was 38 months. CONCLUSION: The cause of venous obstruction and the presence of symptoms which are resistant to medical treatment are the main indications to ilio-femoral venous revascularization. The choice of the optimal treatment in each single case yields satisfactory results.
