A randomized controlled trial to evaluate the efficacy of ultrasound-guided laser photocoagulation for treatment of benign thyroid nodules.

This randomized controlled study was designed to test the efficacy and safety of percutaneous ultrasound (US)-guided laser photocoagulation (PLP) for treatment of subjects with compressive symptoms due to benign thyroid nodules and/or at high surgical risk. Twenty six subjects were randomized to the intervention (no. 13, age 68+/-3 yr, mean+/-SEM) or observation (no. 13, age 71+/-2 yr) groups. In the control group, the volume of nodules did not significantly change over the 30 week period of observation. In the intervention group, median nodule volume at baseline was 8.2 ml (range 2.8-26.9) and was not significantly different from that of the control group. Nodules decreased significantly (p<0.0001) by 22% after 2 weeks (6.5 ml; range 2.4-16.7) and by 44% after 30 weeks (4.6 ml; range 0.69-14.2). Energy given was correlated (p<0.05) with the reduction of thyroid nodule volume. All patients tolerated the treatment well and reported relief from compressive and cosmetic complaints (p<0.05). At the time of enrolment 7/13 (54%) and 6/13 (46%) of patients in the intervention and control groups, respectively, had sub clinical hyperthyroidism. PLP normalized thyroid function at 6 and 30 weeks after treatment. In conclusion, PLP is a promising safe and effective procedure for treatment of benign thyroid nodules in patients at high surgical risk.

Which therapy to prevent post-thyroidectomy hypocalcemia?

Hypocalcemia is one of the most frequent complications after total extracapsular thyroidectomy (TET). In most of cases it is a transient phenomenon. The aim of this study is to evaluate if and how the oral administration of calcium or calcium combined with D-vitamin could effectively prevent post-thyroidectomy hypocalcemia. A randomized prospective study was performed, recruiting 120 patients who underwent total thyroidectomy. The patients in our series were randomly assigned to one of two groups: group A--patients who received calcium lactogluconate/calcium carbonate (mg 300 per day); group B--patients who received calcium carbonate/cholecalciferol therapy (calcium carbonate: 1500 mg per day; cholecalciferol 400 UI per day). The groups were well matched for age, sex and pathologies. Patients of both A and B groups were divided in two subgroups: those operated on for benign thyroid diseases (A1 and B1) and those operated on for malignancy (A2, B2). Serum calcium assays, performed 24, 48 and 72 hours after surgery, showed mean values of calcemia higher in patients of the B1 and B2 group. Statistical analysis was performed using a Student's t test. Mean serum calcium concentrations on post-operative day one, two and three were higher in patients of the group B (p<<0.01). Early and combined oral administration of both calcium and vitamin D seemed to prove major efficacy in preventing and treating post-operative hypocalcemia, showing mean serum calcium levels higher than those of patients who received only oral calcium administration. Nevertheless, further studies are necessary to validate these data.

Major complications in thyroid surgery: utility of bipolar vessel sealing (Ligasure Precise).

In the present study the Authors tried and assess the advantages of the standard sutureless thyroidectomy performed by the Ligasure Vessel Sealing System, thanks to the use of the dedicated Precise handle. The Authors compared the efficacy of haemostasis and the economical impact of the device, in terms of drug administration and costs. The Authors comparatively analyzed 120 total extracapsular thyroidectomies (TET) performed by the standard operative technique (Group A, control) and 70 TET achieved by the "sutureless technique" (Group B, case). There was a statistically significant decrease of transient postoperative hypocalcemia (5.71% vs 7.5%) and also of mean operative time (about 20 minutes) in patients of the group B. Non significant decrease of other kind of complications (postoperative hemorrhage, transient and permanent inferior laryngeal palsy, stupor of the superior laryngeal nerve, seromas) were also observed. The use of the Ligasure Precise resulted easy, safe and efficient in the Authors' experience. It allowed the decrease of postoperative haemorrhages and mean operative time.

Choledochal cysts in adults: a case report.

We examined a case of choledochal cyst in an adult having congenital dilatation of the bile duct classified, according to Todani's, as type I and treated by excision with hepatic-jejunostomy Roux-en Y. This procedure is recommended as the best treatment for eliminating pancreatitis by pancreaticobiliary disconnection and thus for reducing the risk of malignancy.

[Interstitial laser photocoagulation in liver tumours: our experience].

Interstitial lasertherapy (ILT) is one of the percutaneous thermal procedures allowing the ablation of primary or secondary hepatic lesions. This technique can be performed without general anaesthesia, since the patient is completely painless, in spite of the high temperatures reached, because there are no sensitive fibers around the lesion. This study includes patients with small hepatocarcinomas (< 2 cm) non peripherically sited, far from the gallbladder and the hepatic hilum. Twenty patients suffering from 24 cirrhotic hepatocarcinomas (two patients showed two nodules) have been enrolled for the present study. Mean diameter of lesions was 1.8 cm (1.3-2 cm). One or more 21 G (length 20 cm) Chiba's needles were inserted under sonographic view into the lesions. The laser energy was switched on at 4 Watts for 4-6 minutes, until an amount of energy of 900-1800 Joule was reached. All the patients were discharged 48 hours after the procedure. Triphasic CT-scan with contrast were performed 7 to 14 days after ILT, in order to check its efficacy. CT-scan showed complete necrosis in all the nodules ranging from 1.5 to 3 cm. All the patients received only one IL T session, whose longest duration was 20 minutes. No major complications occurred. ILT of small hepatocarcinomas is a safe, efficient procedure, also feasible without anaesthesia. Differently from percutaneous radiofrequency, in fact, it shows the advantage of less pain, that can avoid the need for general anaesthesia.

[Bile leakage after laparoscopic cholecystectomy: report of three cases in our experience].

Laparoscopic cholecystectomy (LC) is associated with an higher incidence of bile duct injury than open cholecystectomy. There has been concern and the reason why bile leakages are more frequent with LC is yet unclear. Bile collections can occurr because of major about (75%) or minor (about 25%) injuries. Anyway, external biliary decompression is a key factor in the treatment, in order to avoid an emergency intervention. The Authors report their experience concerning 3 cases of bile leakages among a series of 458 LC. Only in one of the three cases the subhepatic space was not drained and an emergency laparotomy was performed. The Authors, on the basis of their own experience and of the data reported in literature, suggest the routinary intraoperative placement of a drainage into the subhepatic space, to be removed, if no complications occur, one day after surgery.

[Granulomatous mastitis: diagnostic and therapeutic problems. Case report and review of the literature].

The granulomatous mastitis is uncommon inflammatory disease of the breast of unknown etiology. The diagnosis is obtained only through hystopathology. We report a case of woman, 41 years old, showing lesions of the breast, that caused strong pain with ulcerations sero-haematic secretion and axillary omolateral lymphadenopathy. The diagnostic workup (sonography, mammography, multiples FNAB of single lesions, the culture of cells and hormonal profile) showed an inflammatory aspecific lesions with presence of atipic cells in nipple's secretion and in FNAB of periareola lesion. We performed an excisional biopsy. The hystopathologic diagnosis showed a granulomatous mastitis, confirming the validity of our diagnostic and therapeutic choices. The excisional biopsy has allowed to avoid an overtreatment and obtain a good aesthetic result.
