Isolated adrenal metastasis: the role of laparoscopic surgery.

BACKGROUND: Solitary adrenal metastases (AM) are rare and their management unclear. Surgery, especially laparoscopic adrenalectomy (LA), is debatable in the management of AM. This retrospective study analysed the feasibility and the results of LA for AM. METHODS: From 1997 to 2003, 16 patients underwent LA for isolated AM. Completeness of resection, postoperative morbidity and follow-up (FU) were recorded. RESULTS: There were 10 synchronous AM and 6 metachronous AM. Primary tumours included lung cancer (n = 9), melanoma (n = 3), mesothelioma (n = 1), rhabdomyosarcoma (n = 1), colonic adenocarcinoma (n = 1) and renal cell carcinoma (n = 1). Five patients required conversion to an open procedure. Minor complications occurred in three patients. Pathology confirmed the diagnosis of AM. Mean tumour size was 60 (range: 15-110) mm. Nine patients (56%) had complete resections, 3 had positive margins and 4 had incomplete macroscopic resections. Mean observed FU was 25 (range: 1-68) months. Median overall calculated survival was 23 months. Overall 5-year survival was 33% (Kaplan-Meyer). At the end of study, 8 patients were alive with a mean FU of 35 months (3 without evidence of disease). No patient presented with local relapse or port-site metastasis. We did not identify any predictive factors. All patients with incomplete macroscopic resection died within 24 months. CONCLUSIONS: LA can achieve an acceptable 5-year survival, comparable to open surgery but with better postoperative comfort. It should be considered for AM with the intention of complete resection. It offers the patient the possibility of tumour resection with the benefit of a laparoscopic approach.

Endoscopic lateral approach thyroid lobectomy: safe evolution from endoscopic parathyroidectomy.

INTRODUCTION: Endoscopic thyroid surgery has been shown to be feasible. Most minimal access procedures have been performed via a midline approach. Based on our experience of more than 500 endoscopic parathyroidectomies via a lateral approach we have used the same method for thyroid lobectomy. METHODS: We present our experience of endoscopic thyroid lobectomy via a lateral approach (ETLA) and review of the results over a 1-year period (2004). Inclusion criteria for ETLA were (1) solitary nodule with atypical/suspicious fine-needle biopsy (FNB) or solitary toxic nodule; (2) lesions with a diameter of < 3 cm. Patients with a history of previous neck surgery or radiation exposure were excluded. All patients underwent postoperative vocal cord checks and plasma calcium evaluation. RESULTS: A total of 742 thyroid procedures were performed during 2004. Among them, 38 patients (5.1%) underwent ETLA. Indications for surgery were suspicious FNB results (36 patients) and a toxic nodule (2 patients). Mean nodule size was 19.2 mm. Mean +/- SD operating time was 102 +/- 27 minutes. All recurrent laryngeal nerves were identified (including one that was nonrecurrent). Of the 38 patients, the superior parathyroid gland was identified in 36 and the inferior parathyroid gland in 33. There were two conversions due to difficulty with the dissection. Two operations were converted because malignancy was diagnosed on frozen section examination. Two patients underwent a delayed completion thyroidectomy when definitive histology necessitated it. There were no permanent operative complications, and all patients were discharged on the first postoperative day. CONCLUSIONS: ETLA offers excellent intraoperative visualization of the vital structures and is a safe alternative to conventional thyroid lobectomy in selected cases.

Endocrine surgical technique: endoscopic thyroidectomy via the lateral approach.

BACKGROUND: Minimal access approaches are increasingly used in endocrine surgery. Several minimal access approaches to the thyroid gland have been described, including a small-incision lateral approach and a video-assisted central approach, but to date no technique has been universally accepted. METHODS: Benefiting from the experience of more than 500 endoscopic parathyroidectomies via a lateral neck approach, the authors developed an endoscopic thyroidectomy based on the same approach and principles. Patients with solitary nodules smaller than 3 cm in diameter and no history of neck surgery or irradiation were offered this operation. A detailed description of the surgical technique is provided. RESULTS: Of the 742 thyroidectomies performed in 2004, 38 (5.1%) were endoscopic thyroidectomies. The mean nodule size was 22-mm (range, 7-47-mm), and the mean operating time was 99 min (range, 64-150-min). In all cases, the recurrent laryngeal nerve was preserved intact, and the superior and inferior parathyroids were identified, respectively, in 36 and 33 of the 38 patients. Two patients required conversion to an open cervicotomy. All patients were discharged the day after surgery. CONCLUSIONS: The described endoscopic lateral approach combines the coherence of the minimal access lateral approach and the benefits of fiberoptic magnification. It is a safe and effective technique in the hands of an appropriately trained surgeon.

[Lateral endoscopic approach for thyroid and parathyroid surgery].

The endoscopic lateral approach in thyroid and parathyroid surgery is achieved by developing the plane between the carotid sheath laterally and the strap muscles medially. This approach allows direct access to the posterior aspect of the thyroid lobe, without the need for the dissection of the strap muscles and without the need for medial retraction of the thyroid during the procedure. The lateral approach aided by endoscopic magnification provides the surgeon with the ideal view with which to safely dissect the vital structures found in the retro-thyroid space such as the inferior thyroid artery, the recurrent laryngeal nerve and the parathyroid glands. This approach was initially adopted in primary hyperparathyroidism caused by a single adenoma that had been localized preoperatively. It is now also offered to patients with an isolated thyroid nodule smaller than 25 mm in diameter requiring surgical excision. Experience with 408 parathyroidectomies and the preliminary results of 38 thyroid lobectomies allows the authors to recommend this technique to appropriately selected patients.

[Abrikossoff tumor of the proximal esophagus misdiagnosed as a thyroid nodule].

The diagnosis of thyroid nodules is straightforward and rarely mistaken. We present a case of a paraesophageal granular cell tumor, discovered incidentally during surgery for what it was diagnosed as a suspicious thyroid nodule by ultrasound and FNA. Complete resection was achieved without disruption of the esophageal mucosa. A terminal branch of the recurrent laryngeal nerve had to be resected en bloc with the tumor. Morphological and immunohistochemical diagnosis was established postoperatively. A review of the literature is presented.

Lymph node involvement in macroscopic medullary thyroid carcinoma.

BACKGROUND: Medullary thyroid carcinoma (MTC) is a rare disease, with variable tendency to lymphatic spread. The aim of this retrospective study was to identify distinctive features of large MTC with and without nodal metastases. METHODS: Between 1993 and 2003, 28 consecutive patients underwent total thyroidectomy and neck node dissection for sporadic MTC larger than 10 mm in diameter. RESULTS: All tumours were confirmed to be malignant with a locally invasive pattern of growth. Lymph node metastases were present in 16 patients (N1) and absent in 12 (N0). There were no statistically significant differences between patients with N0 and N1 tumours concerning age (mean 52.1 versus 53.4 years), male:female ratio (0.7 versus 1.0), basal preoperative calcitonin concentration (mean 3238 versus 3076 pg/ml) and tumour size (23.3 versus 23.9 mm). There were differences in the incidence of tumour invasion (P < 0.001), vascular embolism (P = 0.011) and peritumoral thyroiditis (P = 0.039). Measurement of basal and stimulated calcitonin levels after surgery confirmed biochemical cure in all patients with N0 tumours and half of those with N1 disease (P = 0.006). CONCLUSION: There were no preoperative factors that predicted node status for MTC larger than 1 cm in this series. Total thyroidectomy and nodal dissection remains the optimal treatment.

Results of surgical treatment of sporadic medullary thyroid carcinoma following routine measurement of serum calcitonin.

AIM: The aim of this study was to evaluate the results of the surgical management of medullary thyroid carcinoma (MTC), following the introduction of systematic calcitonin measurement in patients referred for thyroid diseases. METHOD: We included all the patients with elevated calcitonin and MTC from January 1993 to March 2001. RESULTS: Among 8497 patients, MTC was diagnosed in 52 with a mean age of 56.1 years. Thirty-two fine needle biopsies led to diagnose MTC in 19 cases. The median basal pre-operative calcitonin level was 245 pg/ml. Elevated calcitonin serum was the only indicator of MTC in 31 patients. Fifty-one patients underwent total thyroidectomies, with lymphadenectomy in 45. Thirteen patients had lymph node involvement. Post-operatively, 40 (77%) had normal basal and pentagastrin (Pg) stimulated calcitonin serum levels, and remained normal at a mean follow-up of 5.16 years (1.8-8). CONCLUSION: Routine pre-operative measurement of calcitonin should be performed because it is often the only indicator of MTC at an early stage. This could lead to an improved MTC cure rate.

Does iodine-131 meta-iodobenzylguanidine (MIBG) scintigraphy have an impact on the management of sporadic and familial phaeochromocytoma?

OBJECTIVES: To assess the impact of [(131)I]meta-iodobenzylguanidine ((131)MIBG) scintigraphy on the management of phaeochromocytoma. DESIGN AND PATIENTS: Between 1982 and 2002, 83 patients with histologically proven phaeochromocytoma or paraganglioma were investigated using (131)MIBG scintigraphy. Seventeen of these patients, with a hereditary form of the disease, presented with 23 phaeochromocytomas [three neurofibromatosis type 1 (NF1), five von Hippel-Lindau disease (VHL), eight multiple endocrine neoplasia type 2A (MEN2A) and one type 2B (MEN2B)]. RESULTS: MIBG uptake was observed in 44/54 sporadic phaeochromocytomas (sensitivity 81.5%), 14/23 familial phaeochromocytomas (60.9%), 3/6 paragangliomas and 4/6 malignant phaeochromocytomas. No significant correlations were found between the degree of tracer uptake, tumour size and urinary metanephrine levels. No patients undergoing surgery for sporadic phaeochromocytoma had a second tumour located. Nine of 54 sporadic phaeochromocytomas had normal or mildly elevated urinary metanephrine levels (< 1.5 greater than normal). In eight of these patients, (131)MIBG was positive and confirmed the diagnosis of phaeochromocytoma. In malignant phaeochromocytomas (n = 6), MIBG demonstrated additional lesions not detected with computed tomography (CT) and/or magnetic resonance imaging (MRI) in three cases. The MIBG findings in the group with apparently sporadic paragangliomas (n = 6) were negative in four cases and failed to detect a cervical lesion in one multifocal paraganglioma. CONCLUSION: (131)MIBG was useful in confirming the diagnosis in phaeochromocytomas with low levels of catecholamine secretion. It contributed little to the management of patients when used as a means of screening for multifocality in sporadic phaeochromocytoma, or the management of patients with familial phaeochromocytoma. However, MIBG can be an informative method of investigation when dealing with malignant/ectopic forms, although the sensitivity of MIBG is lower in this group of patients.

Identification of patients with a non-recurrent inferior laryngeal nerve by duplex ultrasound of the brachiocephalic artery.

A non-recurrent inferior laryngeal nerve (NRILN) is a rare anomaly that may increase the risk of injury during thyroid surgery. A NRILN results from an embryologic developmental abnormality of the aortic arches, demonstrated by the absence of the brachiocephalic artery and the presence of an aberrant subclavian artery (arteria lusoria). In our experience 100% of 104 patients with a NRILN were shown to have these abnormalities. We postulated that duplex scanning of the brachiocephalic artery could identify patients at risk of a NRILN. Twelve patients with an operative diagnosis of a right NRILN and associated vascular abnormalities underwent postoperative duplex scanning of the brachiocephalic artery. The examination was performed using a 7.5 or 3.5 MHz transducer. The average duration of assessment was 5 min. The absence of the brachiocephalic artery and the direct origin of the right common carotid artery from the arch of the aorta were demonstrated in each patient. Duplex scanning is a simple noninvasive method of identifying patients with the arterial abnormalities responsible for a NRILN. This may be used in the preoperative assessment of selected patients.

[Video-assisted parathyroidectomy in the management of patients with primary hyperparathyroidism].

INTRODUCTION: In recent years, different minimally invasive techniques of parathyroidectomy have been described. We performed a retrospective study to evaluate the indications and results of video-assisted parathyroidectomy (Vap) in the management of our patients with primary hyperparathyroidism (PHPT). MATERIALS AND METHODS: During the last 5 years (1998-2002), we operated on 528 patients with PHPT. Vap was proposed for patients with sporadic PHPT, without associated goiter and without previous neck surgery, in whom a single adenoma was localized by means of sonography and/or sestamibi scanning. Vap was performed by lateral approach with insufflation for patients with adenoma located deeply in the neck and by gasless midline approach for patients with adenoma located anteriorly. A quick parathyroid (qPTH) assay was used during the surgical procedures. Calcemia, phosphoremia and PTH were systematically evaluated in patients on days 1 and 8, 1 month and 1 year after surgery. All patients underwent pre-operative and postoperative investigations of vocal cord movements. RESULTS: Among 528 patients with PHPT, 228 (43%) were not eligible for Vap: associated nodular goiter (99 cases), previous neck surgery (42 cases), suspicion of multiglandular disease (25 cases), lack of pre-operative localization (48 cases), and miscellaneous causes (14 cases). Vap was performed in 300 patients with sporadic PHPT: 282 lateral access, 17 midline access and 1 thoracoscopy. Median operative time was 50 min (20-130 min). Conversion to conventional parathyroidectomy was required in 42 patients (14%): missed adenomas (11 cases), difficulties of dissection (7 cases), multiglandular disease correctly predicted by qPTH (10 cases); qPTH assay false negative results (3 cases), sestamibi scan false positive results (10 cases) and 1 sonography false positive result. One patient presented definitive recurrent nerve palsy. One patient had a persistent PHPT and one other patient had a recurrent PHPT. CONCLUSION: Vap can be proposed for more than half of patients with PHPT. In our experience Vap and conventional parathyroidectomy are complementary. Immediate results of Vap are similar to those obtained with conventional parathyroidectomy but no conclusions can be drawn in terms of influence of Vap on the outcome of the patients operated for PHPT.

[Spontaneous cervical haematoma due to extracapsular haemorrhage of a parathyroid adenoma: a report of 2 cases].

The usual clinical manifestations of a parathyroid adenoma are due, in most of the cases, to hypercalcemia. The development of a spontaneous cervical or cervicomediastinal haematoma is a rare form of presentation. In case of a spontaneous cervical haematoma associated with dysphagia: measurement of serum calcium, phosphate and parathyroid hormone allows the diagnosis of haematoma due to extracapsular haemorrhage from a parathyroid adenoma. We report herein 2 cases.

[Lessons learned from 274 laparoscopic adrenalectomies].

AIMS: To define the role of minimally invasive video-assisted surgery in the surgical management of adrenal disease and discuss the respective indications of the trans and retroperitoneal video assisted approaches. MATERIALS AND METHODS: During the last 8 years (1994-2001), 330 adrenalectomies were performed in 305 patients: 274 (83%) laparoscopic approaches and 56 (17%) open approach. Open surgery was reserved for patients presenting with large or malignant tumours (29 cases), multiple and/or extraadrenal phaeochromocytomas (13 cases), previous intraabdominal intestinal surgery (10 cases), and in those requiring concomitant intraabdominal surgery (4 cases). Laparoscopic adrenalectomy was performed using the lateral transperitoneal approach for 89 Conn's syndrome, 67 Cushing's syndrome, 2 virilizing tumours, 51 phaeochromocytomas and 65 non secretory tumours greater than 4 cm in diameter. Nineteen patients underwent bilateral adrenalectomy. RESULTS: There were no deaths. Twenty patients (7.3%) had a complication. Eleven cases required open conversion (4%) because of difficulties with dissection (8 cases), preoperative suspicion of malignancy (2 cases), and one pneumothorax. The average size of tumours was 34 mm (7-110 mm). There were 18 malignant tumours (6.5%): 8 adrenocortical carcinomas, 1 leiomyosarcoma, and 9 metastases. All patients with hormonally secreting tumours were cured of their endocrinopathy. There was 1 death secondary to hepatic metastases in a patient with an adrenocortical carcinoma. CONCLUSION: Most adrenal tumours are suitable for video assisted excision. The only absolute contraindication is an invasive carcinoma requiring an extended excision. The lateral, transperitoneal approach is the most suitable for tumours greater than 5-6 cm in diameter. Both the transperitoneal or retroperitoneal approaches are suitable for smaller tumours depending on operator choice and experience. However in the presence of a large right lobe of liver or previous intraabdominal surgery the retroperitoneal approach may be preferable.

VATS is an adequate oncological operation for stage I non-small cell lung cancer.

OBJECTIVES: This study was designed to determine the long-term prognosis of video-assisted thoracic surgery (VATS) vs. open lung resections for patients with pathological stage I non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: The medical records of all patients who underwent lung resection for a pathological stage I NSCLC were reviewed for the period from 1990 to 1999, by screening of a database into which data were entered prospectively. There were 511 patients (430 males and 81 females) whose age averaged 63+/-10 years who underwent 515 lung resections. Our VATS experience began in 1993 with selected stage I patients, and since that date an average of one patient on four was managed with VATS. Lung resections consisted of 25 wedge resections or segmentectomies (seven VATS), 390 lobectomies (92 VATS), 19 bilobectomies (one VATS) and 81 pneumonectomies (ten VATS). Lymph node dissection was performed in all cases. RESULTS: There were significantly more females (P=0.01) and adenocarcinoma (P=0.02) in the VATS group (n=110) when compared to the open group (n=405). Tumour size averaged 4+/-2 cm in the open group and 3+/-2 cm in the VATS group (P=0.04). The distribution of T1/T2 tumours was 97/308 and 50/60, respectively (P=0.0001). At follow-up, cancer recurrence could be documented in 117 patients, with no difference of incidence between the two groups (22.5 vs. 24.5%; P=0.64). Estimated Kaplan-Meier 5-year survival rates, including the operative mortality as well as any cancer-related and unrelated death, were 62.8% (confidence interval (CI): 56.8-68.7%) vs. 62.9% (CI: 51.4-74.4%), respectively (P=0.60). The advent of VATS did not influence the patients' survival: 5-year survival rate was 63.9% (CI: 55.3-72.5%) for the period from 1990 to 1992, and 58.8% (CI: 51.7-65.9%) for the period from 1993 to 1999 (P=0.65). Subgroups survival analysis according to the T status did not show any statistically significant difference between the two groups. CONCLUSIONS: VATS lung resection with lymph node dissection achieved a 5-year survival similar to that achieved by the conventional approach. VATS is a valuable option for the management of selected patients with an early-stage NSCLC.

[Juvenile dermatomyositis in the Nice area: a retrospective study 1991-2001].

INTRODUCTION: Juvenile dermatomyositis is a rare disease. We conducted a retrospective chart review on patients with juvenile dermatomyositis diagnosed in the Nice area from 1991 to 2001. Our purpose was to review diagnosis criteria and treatment strategies. PATIENTS AND METHODS: The cases of juvenile dermatomyositis were identified by phone investigation of physicians of the departments of paediatrics, dermatology, rheumatology and internal medicine. RESULTS: Seven cases of juvenile dermatomyositis (sex ratio M/W: 0.75, medium age: 7.7 years) were identified. Myalgia and/or weakness were the main reasons for initial consultation. Cutaneous lesions were present in all patients on initial presentation. Muscular enzymes were abnormal in 4 cases out of 7. Muscular biopsy was conducted in 6 patients. In one case, MRI revealed an inflammatory involvement although no clinical or biological sign existed. Systemic corticosteroids was the initial treatment, associated with monthly intravenous immunoglobulins in 5 cases, allowing initial control of the disease in all cases. The other therapies were: methotrexate (3 cases), ciclosporin A (1 case), and chloroquine (2 cases). The evolution was monocyclic in three cases, polycyclic in four cases. With a median follow-up of two years, all the patients are alive: five under treatment, three still in first flare. COMMENT: The diagnosis strategy seems relevant because at least 3 criteria of Peter and Bohan were found in 6/7 patients. Muscular biopsy appears fundamental in the diagnosis strategy. MRI was useful when it was conducted but its use has to be assessed. Therapies were those of previous published studies, except for the use of intravenous immunoglobulins as first-line treatment, associated with corticosteroids. This strategy may be justified for corticosteroid-sparing purposes. CONCLUSION: Working on a real, well-codified strategy of diagnosis and treatment would enhance the uniform management of these patients.
