Closure of cutaneous incision after thyroid surgery: A comparison between metal clips and cutaneous octyl-2-cyanoacrylate adhesive. A prospective randomized clinical trial

Octyl-2-cyanoacrylate (Dermabond, Ethicon Inc.) has been introduced in clinical practice as an ideal system of closure of wounds, but no studies have confirmed the advantages of wound closure performed with Dermabond compared to skin staples (Proximate, Ethicon Inc.) in thyroid surgery. The objective of this study is to evaluate the short- and long-term results of wound closure in thyroid surgery performed with Dermabond (DERM) versus Proximate (PROX). Seventy patients after thyroidectomy were randomly assigned into the two groups (DERM vs PROX). The postoperative and the long-term outcomes were clinically evaluated by physicians, and the Stony Brook scar evaluation scale has also been used. The patients' satisfaction with the early postoperative management and with the cosmetic outcomes has been assessed by a numerical scale ranging from 0 to 10. Results were compared using appropriate statistical tests. Thirty-two patients used DERM, while 38 patients used PROX. Immediate results showed difficult application in two cases DERM (6.2%) and hyperemia in one case DERM (3.1%). Early results showed edema in eight cases DERM (25%) vs two cases PROX (5.2%; p<0.05); patients' satisfaction: optimum judgement in 100% DERM vs 15.7% PROX (p< 0.001); patients' self aesthetic evaluation: PROX higher percentage of excellent results vs DERM (p<0.005). After one month, results showed edema in nine cases DERM (28.8%) vs two cases PROX (5.2%; p<0.01), while after 6 months, DERM had lesser symptoms than PROX (p< 0.01). Octyl-2-cyanoacrylate has proven to be effective and reliable in the skin closure of cervical incision similar to suture with staples and yields similar final cosmetic outcomes. Because Dermabond offers the advantage of better management in the early postoperative phase, the patients' satisfaction is clearly better. © Springer-Verlag 2010

Challenging differential diagnosis between lipoma and well-differentiated liposarcoma in the retroperitoneum. A case report

Liposarcomas are the most common type of sarcomas arising in the retroperitoneum. Retroperitoneal lipomas are extremely rare. They should be distinguished from well-differentiated liposarcomas in order to provide the appropriate treatment. A 53-years-old male was admitted with the presence of a palpable mass in the upper abdomen. Contrast enhanced computerized tomography (CT) of the abdomen and pelvis showed a 20x12 cm mass arising in the retroperitoneum and inglobing the celiac and superior mesenteric trunks. Because of unresectability an open surgical biopsy was performed. Histological examination showed the presence of adipose tissue with diffuse liponecrosis without definitive features of neoplasia. At six-month follow-up a CT documented an increase of the tumor to 22x13 cm. The mass was stable at the CT, performed at 1-year follow-up. Given the impossibility to distinguish well-differentiated liposarcomas from lipomas and the in the present case of unresectable retroperitoneal mass, an observational follow-up was a justified

Treatment of mild malnutrition and reduction of morbidity in major abdominal surgery: randomized trial on 153 patients]

Severe malnutrition (defined as weight loss more than 10% in a period of six months) is considered an important risk factor in major abdominal surgery, because of a higher post-operative mortality and morbidity. The aim of our study is to assess the role of mild malnutrition (weight loss low than 10% in a period of six months) as a risk factor in major abdominal surgery and to evaluate the efficacy of therapy in order to improve outcomes in terms of in-hospital mortality, length of hospital stay and post-operative complications. Moreover, we evaluated serum albuminemia and lymphocyte count, important nutritional index, as predictive risk factors. We performed a randomized prospective trial, and admitted in our institution 153 adult patients, 43 with mild malnutrition and 110 without. The malnourished patients were randomized in two groups: the first one received oral immunonutrition (Impact Oral) for 7-10 days before surgery (22 pz), the second one received no nutritional support. We observed a higher number of complications in the non-treated malnourished patients (57%) versus both the treated malnourished patients (13.6%) and the normal group (19%) (p<0.001). Increased morbidity was observed in patients with serum albuminemia <2.8 gr/dl (69.2%) and with lymphocyte count <1.500 mm3 (57%). Nutritional enriched support demonstrated his efficacy in reducing morbidity, and length of hospital stay. Pre-operative oral immunonutrition might be suggested and established in all the patients with mild malnutrition that will be operated on major abdominal surger
