Long-term outcomes of laparoscopic adrenalectomy for Cushing disease.

Introduction: In the surgical management of the patients with Cushing syndrome (CS), minimal invasive adrenalectomy (MA) has become the procedure of choice to treat adrenal tumors with a benign appearance ≤6 cm in diameter. Authors evaluated medium- and long-term outcomes of laparoscopic adrenalectomy (LA) for CS or subclinical CS (sCS), performed for ten years in an endocrine surgery unit.

Methods: We retrospectively reviewed 21 consecutive patients undergone LA for CS or sCS from 2003 to 2013.

Controversies in the surgical management of thyroid follicular neoplasms. Retrospective analysis of 721 patients.

The most appropriate surgical management of "follicular neoplasm/suspicious for follicular neoplasm" lesions, is still controversial. Analysing and comparing the experience of two units for endocrine surgery, we retrospectively evaluated 721 patients, surgically treated after a follicular neoplasm diagnosis. Total thyroidectomy was routinely performed in one Institution, while in the other one it was selectively carried out.

Impact of parathyroidectomy on cardiovascular outcomes and survival in chronic hemodialysis patients with secondary hyperparathyroidism. A retrospective study of 50 cases prior to the calcimimetics era.

Background: In chronic hemodialysis patients with secondary hyperparathyroidism, pathological modifications of bone and mineral metabolism increase the risk of cardiovascular morbidity and mortality. Parathyroidectomy, reducing the incidence of cardiovascular events, may improve outcomes; however, its effects on long-term survival are still subject of active research.

Methods: From January 2004 to December 2006, 30 hemodialysis patients, affected by severe and unresponsive secondary hyperparathyroidism, underwent parathyroidectomy - 15 total parathyroidectomy and 15 total parathyroidectomy + subcutaneous autoimplantation.

Laparoscopic adrenal surgery: ten-year experience in a single institution.

Background: Minimal invasive adrenalectomy has become the procedure of choice to treat adrenal tumors with a benign appearance, ≤ 6 cm in diameter and weighing < 100 g. Authors evaluated medium- and long-term outcomes of laparoscopic adrenalectomy (LA), performed for ten years in a single endocrine surgery unit.

Methods: We retrospectively reviewed 88 consecutive patients undergone LA for lesions of adrenal glands from 2003 to 2013.

Predictive value of nodal metastases on local recurrence in the management of differentiated thyroid cancer. Retrospective clinical study.

Background: The significance of nodal metastases, very common in papillary thyroid cancer, and the role of lymph node dissection in the neoplasm management, are still controversial. The impact of lymph node involvement on local recurrence and long-term survival remains subject of active research. With the aim to better analyze the predictive value of lymph node involvement on recurrence and survival, we investigated the clinico-pathological patterns of local relapse following total thyroidectomy associated with lymph node dissection, for clinical nodal metastases papillary thyroid cancer, in order to identify the preferred surgical treatment.

Role of preoperative adrenergic blockade with doxazosin on hemodynamic control during the surgical treatment of pheochromocytoma: a retrospective study of 48 cases.

Authors evaluated the effects of selective adrenergic blockade by means of doxazosin on blood pressure in 48 patients operated on for pheochromocytoma by a multicenter retrospective study. Age, tumor size, surgical approach, and operative time were analyzed as predictive factors of intraoperative hypertensive crises. Forty-eight patients underwent adrenalectomy--four open surgery and 44 laparoscopic surgery--for pheochromocytoma of adrenal glands from 1998 to 2008 after preoperative administration of doxazosin.

Multifocal thoracic chordoma mimicking a paraganglioma.

Chordoma of thoracic vertebras is a very rare locally invasive neoplasm with low grade malignancy arising from embryonic notochordal remnants. Radical surgery remains the cornerstone of the treatment. We describe a case of multifocal T1-T2 chordoma, without bone and disc involvement, incidentally misdiagnosed as a paraganglioma, occurring in a 47-year-old male asymptomatic patient.

Foregut duplication of the stomach diagnosed by endoscopic ultrasound guided fine-needle aspiration cytology: case report and literature review.

Gastric duplication cyst (GDC) with a pseudostratified columnar ciliated epithelium is an uncommon malformation supposed to originate from a respiratory diverticulum arising from the ventral foregut. Morphologic appearance of GDCs is variable, depending on the density of their contents. GDCs are often misdiagnosed as solid masses by imaging techniques, and as a consequence they may be wrongly overtreated.

Laparoscopic treatment of pheochromocytomas smaller or larger than 6 cm. A clinical retrospective study on 44 patients. Laparoscopic adrenalectomy for pheochromocytoma.

Introduction: Laparoscopic adrenalectomy is a gold standard for the treatment of pheochromocytomas less than 6 cm in diameter. Given the difficulty in dissecting the adrenal glands, the presumed increase in the risk of malignancy, and capsular disruption there is controversy regarding minimally invasive surgery for neoplasms greater than 6 cm. The aim of this study was to report laparoscopic adrenalectomy results in 44 patients with pheochromocytomas either larger or smaller than 6 cm.

Cytologically undetermined thyroid's follicular lesions: surgical procedures and histological outcome in 472 cases.

Background: Fine needle cytology (FNC) of thyroid nodules is not always diagnostic. Most of FNCs undeterminated for malignancy belong to the cytological class of "follicular neoplasm/suspicious for follicular neoplasm" lesions (FN). In this group only 10-30% of cases are malignant and the most appropriate surgical management is still controversial.

Role of parathyroidectomy on anemia control and erythropoiesis-stimulating agent need in secondary hyperparathyroidism of chronic kidney disease. A retrospective study in 30 hemodialysis patients.

Background: Parathyroidectomy (Ptx) ameliorates anemia (A) and reduces postoperative erythropoiesis-stimulating agent (ESA) requirement. The authors retrospectively evaluated the effects of successful Ptx on chronic A and ESA need in 30 2HPT patients.

Methods: From 2004 to 2009,30 anemic hemodialysis (HD) patients, affected by severe 2HPT, underwent Ptx -15 total parathyroidectomy (TP) and 15 TP + subcutaneous autoimplantation (TPai).

The role of percutaneous US-guided drainage in the treatment of splenic abscess. Case report and review of the literature.

Splenic abscess is an uncommon but potentially life-threatening disease that generally occurs in patients with neoplasia, immunodeficiency, hemoglobinopathies, trauma, metastatic infection, splenic infarction and diabetes. Splenic abscess should be considered in a patient with fever, left upper abdominal pain, and leukocytosis. Splenectomy has been the gold standard treatment for splenic abscess, however, burdened by high morbidity rate related clinical conditions of the patient.

Tracheal necrosis, oesophageal fistula: unusual complications of thyroidectomy. Report of two case and literature review.

Background: Thyroidectomy is considered a low-risk operation. The authors report a case of tracheal necrosis after total thyroidectomy for multinodular goiter with bilateral adenomas, and a case of oesophageal fistula after total thyroidectomy for papillary cancer.

Methods And Results: The patient with tracheal perforation was treated by a non operative management after clinical stabilization.

Intestinal occlusion caused by endometriosis of the sigmoid colon.

Endometriosis (E) is an estrogen-dependent inflammatory disorder that is observed in approximately 10% of women in childbearing age, and is the most common benign gynecological disorder requiring hospitalization. In 5% of cases, there is an involvement of the gastrointestinal tract, for the most part of the sigmoid colon and rectum (~ 90%). However intestinal obstruction due to severe stenosis of the sigmoid colon, as in the case described by the authors, is rare.

Radiofrequency-assisted partial nephrectomy for metanephric adenoma: a case report and literature review.

Metanephric adenoma (MA) is a rare benign tumor, diagnosis of which is often carried out after surgical treatment. In case of peripheral lesions, a partial nephrectomy (PN)--either open or laparoscopic may be preferred--and, furthermore, a radiofrequency (RF)-assisted procedure may facilitate adequate hemostasis. In November 2010, the authors performed a RF-assisted PN, according to Habib's technique, using a 4-needle bipolar device, on a woman affected by a small exophytic MA of the right kidney.

An unpredicted case of tracheal necrosis following thyroidectomy.

Tracheal rupture is a rare condition, and its most common cause is head and neck injury. Nontraumatic disruption of the anterolateral fibrocartilaginous trachea is an exceptional complication following thyroidectomy with few cases reported in literature. We report a case of upper tracheal necrosis arising 15 days after uneventful total thyroidectomy and resulted in pneumomediastinum and subcutaneous emphysema.

[Surgical treatment of secondary hyperparathyroidism. A clinical study of 70 patients].

Aim: The authors analyze the short and long-term results of surgical treatment in 70 consecutive patients operated on from for secondary Hyperparathyroidism (2HPT) of chronic kidney disease (CKD).

Material Of Study: Seventy patients affected by 2HPT of CKD, in hemodialytic treatment, were observed from January 1999 to January 2009. Twenty-seven patients were submitted to total parathyroidectomy (TP), 36 pts were submitted to total parathyroidectomy plus subcutaneous autoimplantation (TP ai), 7 pts were submitted to subtotal parathyroidectomy (SP).

[Lymphectomy in differentiated thyroid carcinoma].

Papillary and follicular thyroid carcinoma are still characterised by unclear biological and clinical behaviour with an autoptic incidence higher than the clinical incidence. Lymph-node involvement represents a prognostic factor that may increase the rate of local relapse, reducing long-term survival only in high risk patients--age > 45 years, M+, T > 3 cm, extra thyroidal extension, follicular histotype. The authors analyse the role of lymph-node cervical dissection.

[The RET gene and medullary thyroid cancer: from mutations to the planning of therapy].

The RET gene codes for a tyrosine kinase receptor, expressed in neural crest derived cells playing a central role during embryogenesis. The RET proto-oncogene is responsible for medullary thyroid cancer and multiple endocrine neoplasia type 2. To date, more than 50 germline point mutations have been described.
