Surgical management of gynecomastia: experience of a general surgery center.

AIM: Gynecomastia is a common finding in male population of all ages. The aim of our study was to present our experience and goals in surgical treatment of gynecomastia. PATIENTS AND METHODS: Clinical records of patients affected by gynecomastia referred to our Department of Surgery between September 2008 and January 2015 were analyzed. 50 patients were included in this study. RESULTS: Gynecomastia was monolateral in 12 patients (24%) and bilateral in 38 (76%); idiopathic in 41 patients (82%) and secondary in 9 (18%). 39 patients (78%) underwent surgical operation under general anaesthesia, 11 (22%) under local anaesthesia. 3 patients (6%) presented recurrent disease. Webster technique was performed in 28 patients (56%), Davidson technique in 16 patients (32%); in 2 patients (4%) Pitanguy technique was performed and in 4 patients (8%) a mixed surgical technique was performed. Mean surgical time was 80.72±35.14 minutes, median postoperative stay was 1.46±0.88 days. 2 patients (4%) operated using Davidson technique developed a hematoma, 1 patient (2%) operated with the same technique developed hypertrophic scar. CONCLUSIONS: Several surgical techniques are described for surgical correction of gynecomastia. If performed by skilled general surgeons surgical treatment of gynecomastia is safe and permits to reach satisfactory aesthetic results.

Intraoperative recurrent laryngeal nerve monitoring in thyroid surgery: is it really useful?

AIM: The aim of this study was to evaluate the ability of intraoperative recurrent laryngeal nerve monitoring to predict the postoperative functional outcome and the potential role of this technique in reducing the postoperative nerve palsy rate. MATERIALS AND METHODS: Between June 2007 and December 2011, 1693 consecutive patients who underwent thyroidectomy by a single surgical team were evaluated. We compared patients who have had a neuromonitoring and patients who have undergone surgery with the only visualization. Patients in which NIM was not utilized (Group A) were 942 against the others 751 (group B). RESULTS: In group A there were 28 recurrent laryngeal nerve injuries (2.97%) of which 21 were transients (2.22%) and 7 were permanents (0.74%). In group B there were 20 recurrent laryngeal nerve injuries (2.66%) of which 14 (1.86%) transients and 6 (0.8%) permanents. Differences between the two groups were not statistically significative. CONCLUSIONS: The technique of intraoperative neuromonitoring in thyroid surgery is safe and reliable in excluding postoperative recurrent laryngeal nerve palsy; it has high accuracy, specificity, sensitivity and negative predictive value. Neuromonitoring is useful to identify the recurrent laryngeal nerve and it can be a useful adjunctive technique for reassuring surgeons of the functional integrity of the nerve but it does not decrease the incidence of injuries compared with visualization alone. Its application can be particularly recommended for high-risk thyroidectomies.

Risk factors in reoperative thyroid surgery for recurrent goitre: our experience.

AIM: Reoperative thyroid surgery is an uncommon operation associated with a higher complication rate; we reviewed our series of patients on whom reoperative thyroid surgery was performed. METHOD: 106 patients had a thyroid reoperation for recurrent multinodular goiter (93 patients), recurrent thyrotoxicosis (3) or suspected malignancy (10); bilateral completion thyroidectomy was performed in 68 cases, lobectomy in 36, removal of a mediastinal recurrence and of a pyramidal remnant in 1 patient respectively. RESULTS: Temporary hypoparathyroidism occurred in 41 patients (38.67%), definitive in 7 (6.6%), transient recurrent laryngeal nerve palsy in 5 (4.71%), permanent nerve palsy in 1 (0.94%); in 3 cases (2.83%) surgical revision of haemostasis was necessary for postoperative haemorrhage. After monolateral surgery we had 13 cases of transient hypoparathyroidism (34.21%), 2 of definitive (5.26%) and 1 transient recurrent laryngeal nerve palsy (2.63%); after bilateral surgery we had 29 cases of transient hypoparathyroidism (42.64%), 5 of definitive (7.35%), 4 of transient recurrent laryngeal nerve palsy (5.88%), 1 of definitive (1.47%) and 3 of postoperative bleeding (4.41%). CONCLUSIONS: Reoperative thyroid surgery is a technical challenge with a high incidence of complications. Scarring, edema and friability of the tissues together with distortion of the landmarks make reoperative surgery hazardous. A higher risk of complications is described when previous surgery has been performed on both sides. Total thyroidectomy should be considered the procedure of choice for benign multinodular goiter eliminating the potential of a reoperation. Whenever necessary, reoperative thyroidectomy may be performed safely with little morbidity in experienced hands.

Intraoperative parathyroid hormone assay during focused parathyroidectomy for primary hyperparathyroidism: is it really mandatory?

AIM: Intraoperative parathyroid hormone (PTH) assay has become an essential tool in focused parathyroid surgery. The aim of this study was to evaluate the present role of intraoperative PTH monitoring during focused parathyroidectomy for primary hyperparathyroidism in our experience. METHODS: One hundred sixty-one patients were submitted to focused parathyroidectomy with rapid intraoperative Parathyroid hormone assay monitoring. RESULTS: A >50% decrease of PTH occurred in 147 patients (91.3%); in this group persistent hypercalcemia was found in 1; in the remaining 14 (8.7%) values of PTH decreased less than 50% and bilateral neck exploration was performed. An additional pathologic parathyroid was removed in 8 cases, a third in one; in the other five further neck exploration was negative and in four of these persistent postoperative hypercalcemia was demonstrated. In 136 patients >50% decrease of PTH was obtained after 10 minutes, in the other 11 after 20. The overall operative success of the patients was 96.9% with a 5.6% incidence of multiglandular disease. Intraoperative parathormone monitoring changed the operative management in 8.7% of cases. Intraoperative parathormone monitoring was accurate in predicting operative success or failure in 98.7% of patients, with a sensitivity of 99.3%, a specificity of 92.8%, a positive predictive value of 99.3% and a negative predictive value of 92.8%. DISCUSSION AND CONCLUSION: The measurement of intraoperative PTH represents a useful tool to assist the surgeon during parathyroid surgery and its routine use significantly improves cure rates of focused parathyroidectomy. We believe that the use intraoperative PTH is still mandatory in focused parathyroidectomy avoiding relapses and consequent reintervention.

Isolated inguinal endometriosis. Case report with ultrasonographic preoperative diagnosis.

Inguinal endometriosis is rare and accounts for 0.3-0.6% of patients affected by endometriosis. A correct preoperative diagnosis is rare. Diagnosis is frequently made by histologic examination. A 36-year-old nulliparous woman presented with a painful mass in her right groin of 2 years duration. The pain fluctuated according to the menstrual period. Physical examination revealed an elastic hard mobile mass measuring 2 x 2 cm in the right inguinal region. Ultrasound examination confirmed a hypoechoic tumor in the right inguinal region with poorly defined boundaries and perilesional and intralesional vascular flow suspect for endometriosis. Wide excision of the lump with a part of the round ligament was carried out. Histology showed endometrial glands and stroma within the fibrous tissue. The patient had an uneventful recovery and was discharged the next day. After surgery, the pain disappeared completely. No signs of recurrence occurred at approximately 16 months after the surgery. Although rare, extrapelvic endometriosis should be considered in the differential diagnosis in women of reproductive age presenting with an inguinal mass, especially if the groin mass is associated in size and tenderness with menstrual variability. US appearance is very useful in diagnosis so ultrasonography can be considered the examination of choice.

[New techniques in parathyroid surgery]. / Nuove Tecniche nella chirurgia delle paratiroidi.

The diseases of parathyroid glands have assumed a growing importance for innovations in diagnosis and surgery which have enabled a more precise identification and therapy. Use of Sesta-MIBI scintigraphy allows a correct localization of the adenoma; the introduction of intraoperative monitoring of intact parathyroid hormone made possible unilateral neck exploration with a mini-incision above the adenoma. The emergence of videotechnology has led the innovation of endoscopic parathyroidectomy, realized for the first time in 1996 and subsequently performed without the use of CO2. Currently, the SPECT scintigraphy allows a three-dimensional vision of the adenoma and is the more precise localization study, allowing to use mini-invasive access. Prerequisite for the use of minimally invasive techniques is the determination of intraoperative PTH, possible with various techniques. Our experience is based on 135 patients undergoing parathyroidectomy in the last 8 years with 5 cases of persistent hyperparathyroidism submitted to reoperation, an average hospital stay of 2 days and only 6 complications (1 bleeding and 5 temporary hypoparathyroidisms). The use of new technologies in parathyroid surgery can achieve optimal results, a better cosmetic result and quicker postoperative recovery, with a low incidence of recurrence and complications.

Primary mesenteric liposarcoma. Report of a case.

Primary mesenteric liposarcomas are very rare neoplasms. The authors report a case of mesenteric liposarcoma recently observed. The patient presented with a history of dyspeptic syndrome, meteorism and abdominal pain associated with a change in bowel habit and constipation. On physical examination there was a large, well-circumscribed, abdominal mass. Computed tomography revealed an abdominal, dishomogeneous, low-density mass. Surgical excision with a tumour-free margin was achieved. The histologic appearances were those of a well-differentiated liposarcoma (atypical lipomatous tumour). The patient is alive and disease-free 33 months after the surgery. Primary mesenteric liposarcoma is often resectable and requires aggressive surgical management; in consideration of the high risk of tumour recurrence, the treatment of choice is a wide surgical excision.
