Abstract
BACKGROUND Calcitonin (Ct) is a sensitive diagnostic biomarker and one of the most important prognostic factors in medullary thyroid cancer (MTC). This study aimed to evaluate progression-free survival and recurrence rates of MTC associated with undetectable compared with normalized serum Ct levels after surgery. METHODS This retrospective observational study included patients operated for MTC at the Digestive and Endocrine Surgery Department of Lyon Sud Hospital Centre between 2000 and 2019. Clinical and pathological factors were correlated with postoperative Ct concentrations. Undetectable and normalized Ct concentrations were defined as below 2 pg/ml and 2-10 pg/ml respectively. RESULTS Overall, 176 patients were treated for MTC, and 127 were considered biochemically cured after surgery. Of these, 24 and 103 had normalized and undetectable Ct concentrations respectively. Patients with Ct level normalization had a 25 per cent risk of disease recurrence, compared with 3 per cent in patients with undetectable Ct levels after surgery. The presence of metastasis in two or more compartments was predictive of failure to achieve undetectable Ct concentrations after surgery and an increased risk of recurrence. CONCLUSION Among patients with biochemically cured MTC, those with undetectable or normalized Ct concentrations after surgery had different risks of recurrence. Simply assessing postoperative Ct normalization can be falsely reassuring, and long-term follow-up is needed.

Abstract
The COVID-19 pandemic commands a major reorganisation of the entire French healthcare system. In France, general rules have been issued nationally and implemented by each healthcare centre, both public and private, throughout France. Guidelines drafted by an expert group led by the French-speaking Association of Endocrine Surgery (AFCE) propose specific surgical management principles for thyroid, parathyroid, endocrine pancreas and adrenal surgery during and after the COVID-19 epidemic.

Poorly differentiated thyroid carcinoma with pleomorphic giant cells-a case report. Virchows Arch 2020; 477:597-601. [PMID: 32239274 DOI: 10.1007/s00428-020-02807-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2019] [Revised: 03/10/2020] [Accepted: 03/25/2020] [Indexed: 11/25/2022]
Abstract
Poorly differentiated thyroid carcinoma (PDTC) refers to a malignant tumour that displays an intermediate prognosis between well-differentiated carcinomas and anaplastic thyroid carcinomas (ATC). In the thyroid, pleomorphic giant cells are observed in ATC or in some non-neoplastic thyroid diseases. We described the case of a 43-year-old woman with a 34-mm nodule in her thyroid right lobe. Microscopic examination revealed an encapsulated tumour with a main solid growth pattern and extensive capsular invasion. Multiple images of angioinvasion were observed. There was neither necrosis nor inflammation. Most of the tumour cells were medium-sized and intermingled with pleomorphic giant tumour cells with bizarre features. The immunoprofile (keratins +, TTF1+, Pax 8+) proved their thyroid origin. By NGS, no molecular alteration was identified. The patient was treated by surgery and radioiodine therapy and she has no recurrence after a follow-up of 24 months. Our case meets all the histological criteria of the Turin proposal for PDTC but with pleomorphic giant cells and is very different from ATC according to clinical, histological and immunohistochemical features. Pleomorphic tumour giant cells in thyroid carcinomas could be present in PDTC and do not always represent dedifferentiation and more aggressive carcinoma, thyroid neoplasm.

Abstract
OBJECTIVE This study is to determine the impact of complications after total thyroidectomy on health-related quality of life (HR-QoL) and to identify significant predictive factors of HR-QoL changes. HR-QoL is usually impaired in patients with thyroid diseases compared to the general population. Thyroidectomy is largely performed in the case of benign thyroid benign and can be associated with long-term complications (vocal cord palsy, hypoparathyroidism). DESIGN The prospective ThyrQoL multicenter trial (NCT02167529) included 800 patients who underwent total thyroidectomy for benign or malignant non-extensive disease in seven French referral hospitals between 2014 and 2016. METHODS HR-QoL was assessed using the MOS 36-item short form health survey (SF-36) self-questionnaire with a 6-month follow-up. RESULTS We observed a significant improvement of HR-QoL 6 months after surgery (P < 0.0001). Postoperative complications were associated with a non-significant impairment of HR-QoL. In multivariable analysis, Graves' disease was associated with a significant improvement of HR-QoL (OR = 2.39 [1.49; 3.84]) and thyroid malignant disease with an impairment of HR-QoL (OR = 1.44 [0.99; 2.08]) after thyroidectomy. CONCLUSION We observed a significant improvement of HR-QoL 6 months after total thyroid surgery for benign thyroid disease.

Molecular testing of BRAF, RAS and TERT on thyroid FNAs with indeterminate cytology improves diagnostic accuracy. Cytopathology 2017; 28:482-487.

Abstract
OBJECTIVE Liquid-based (LB)-FNA is widely recognized as a reliable diagnostic method to evaluate thyroid nodules. However, up to 30% of LB-FNA remain indeterminate according to the Bethesda system. Use of molecular biomarkers has been recommended to improve its pathological accuracy but implementation of these tests in clinical practice may be difficult. Here, we evaluated feasibility and performance of molecular profiling in routine practice by testing LB-FNA for BRAF, N/HRAS and TERT mutations. METHODS We studied a large prospective cohort of 326 cases, including 61 atypia of undetermined significance, 124 follicular neoplasms, 72 suspicious for malignancy and 69 malignant cases. Diagnosis of malignancy was confirmed by histology on paired surgical specimen. RESULTS Mutated LB-FNAs were significantly associated with malignancy regardless of the cytological classification. Overall sensitivity was 60% and specificity 89%. Importantly, in atypia of undetermined significance and follicular neoplasm patients undergoing surgery according to the Bethesda guidelines, negative predictive values were 85.4% and 90% respectively. TERT promoter mutation was rare but very specific for malignancy (5.5%) suggesting that it could be of interest in patients with indeterminate cytology. CONCLUSIONS Mutation profiling can be successfully performed on thyroid LB-FNA without any dedicated sample in a pathology laboratory. It is an easy way to improve diagnostic accuracy of routine LB-FNA and may help to better select patients for surgery and to avoid unnecessary thyroidectomies.

Abstract
OBJECTIVE Inferior laryngeal nerve (ILN) palsy and hypocalcemia remain the two most frequent major complications after thyroid surgery. Their occurrences may be explained by the influence of factors related to the patient, the surgical procedure, thyroid pathology, or the surgeon's technique. This study aims To assess whether systematically following a rigorous surgical technique during thyroidectomy affects postoperative complications and long-term patient recovery. METHODS We conducted a multicenter, cross-sectional study of prospectively collected data in five high-volume referral centers enrolling all patients who underwent thyroid surgery between April 2008 and December 2009. Inferior laryngeal nerve (ILN) palsy and hypocalcemia were systematically assessed during hospitalization based on objective criteria. A six-month follow-up was conducted in cases of early complications. Multivariate regression models were computed to quantify their relationship with potential risk factors. RESULTS A total of 3574 thyroid procedures were completed. Non-visualization of the ILN during dissection and a large thyroid mass were major risk factors for permanent ILN palsy (OR, 4.17 and 2.61, p<0.01) and persistent complications after initial injury (OR, 4.17 and 2.42, p<0.05). The presence of thyroiditis on the surgical specimen was an independent risk factor for permanent hypoparathyroidism and poor recovery after initial dysfunction (OR, 1.76 and 1.88, p<0.05). CONCLUSIONS Thorough meticulous technique in thyroid surgery is a determinant of ILN function but fails to prevent persistent hypoparathyroidism.

Abstract
Abstract
Background
The application of safety principles from the aviation industry to the operating room has offered hope in reducing surgical complications. This study aimed to assess the impact on major surgical complications of adding an aviation-based team training programme after checklist implementation.
Methods
A prospective parallel-group cluster trial was undertaken between September 2011 and March 2013. Operating room teams from 31 hospitals were assigned randomly to participate in a team training programme focused on major concepts of crew resource management and checklist utilization. The primary outcome measure was the occurrence of any major adverse event, including death, during the hospital stay within the first 30 days after surgery. Using a difference-in-difference approach, the ratio of the odds ratios (ROR) was estimated to compare changes in surgical outcomes between intervention and control hospitals.
Results
Some 22 779 patients were enrolled, including 5934 before and 16 845 after team training implementation. The risk of major adverse events fell from 8·8 to 5·5 per cent in 16 intervention hospitals (adjusted odds ratio 0·57, 95 per cent c.i. 0·48 to 0·68; P < 0·001) and from 7·9 to 5·4 per cent in 15 control hospitals (odds ratio 0·64, 0·50 to 0·81; P < 0·001), resulting in the absence of difference between arms (ROR 0·90, 95 per cent c.i. 0·67 to 1·21; P = 0·474). Outcome trends revealed significant improvements among ten institutions, equally distributed across intervention and control hospitals.
Conclusion
Surgical outcomes improved substantially, with no difference between trial arms. Successful implementation of an aviation-based team training programme appears to require modification and adaptation of its principles in the context of the the surgical milieu. Registration number: NCT01384474 (http://www.clinicaltrials.gov).

Abstract
BACKGROUND Adrenocortical carcinoma (ACC) is a rare cancer for which little level evidence exists to guide management. (18)F-FDG PET ((18)F-fluorodeoxyglucose positron emission tomography) is an increasingly used diagnostic tool in patients with suspicious or indeterminate adrenal tumors. In some other solid tumors, (18)F-FDG PET may offer prognostic information that can guide optimal patient treatment. The aim of the present study was to evaluate whether preoperative (18)F-FDG PET based on SUVs assessments has a prognostic value in ACC patients. METHODS A retrospective analysis was performed in patients who underwent (18)F-FDG PET/CT for the evaluation of ACC. Inclusion criteria were an unequivocal diagnosis of ACC; all data from primary diagnosis available; (18)F-FDG PET/CT performed prior to surgery or other treatment of the primary tumor; a minimum of 6-months follow-up for surviving patients. All (18)F-FDG PET/CT procedures were reinterpreted in a blind fashion. RESULTS Thirty-seven patients (23 without metastasis [M0], 14 with metastasis [M1]) fulfilled the study criteria. Median uptake values were tumor standardized uptake values (SUV)(max) = 11 (range: 3-56) and a tumor/liver SUV(max) ratio = 4.2 (range: 1.3-15). Median follow-up was 20 months. Although classic risk factors (tumoral stage, Weiss score) were associated with poor outcome, there was no correlation between primary tumor FDG uptake with overall survival (OS) and disease free survival (DFS) in M0 patients and with overall survival in M1 patients. (18)F-FDG uptake correlated inconsistently with sinister histological features, such as atypical mitoses or necrosis. CONCLUSIONS At initial staging, primary tumor FDG uptake in ACC patients does not correlate with OS and DFS at 2 years. Patient prognosis and treatment strategy should not be based on uptake values.

Abstract
OBJECTIVE To assess, a year after the deployment of the check-list in the centre hospitalier Lyon Sud (CHLS - HCL), the perception of medical and nursing staff regarding the advantages of the check-list and its level of integration within the overall organization of the operating room. TYPE OF STUDY Descriptive study, questionnaires and audits. MATERIALS AND METHODS Distribution of individual questionnaires to the entire operating room staff, and observational audits in the operating room, to objectively assess the quality of implementation of the check-list (level II of the HAS - French National Autority of Health). RESULTS The medical and nursing staff participated equally in using the check-list. This was derived from the individual questionnaires and reinforced by the observational audit; they also revealed an uneven implementation of the three phases, with phase 3 almost never performed. In two-third of the cases, the time-out requirements did not comply with HAS instructions. Nurses and physicians perceived the check-list differently. Even though they agreed that the check-list should be a team effort and is useful, nurses noted a lack of investment and leadership from doctors, in addition to communication problems, which led to a feeling of disrespect towards them when they play the role of the check-list coordinator. CONCLUSION The questionnaire and the audit of practice showed strong adherence to the concept in that the surgical check-list was considered useful by all staff. However, it was also considered to be an added formality and its full implementation was rare in practice. There was a problem of distribution and acceptance of roles with nurses often observing that they were the only ones strictly following the check-list due to a lack of medical investment.

Abstract
BACKGROUND Many authors advocate total or near-total thyroidectomy for thyroid carcinoma. This study examined the relationship between hospital volume of thyroidectomies and choice of bilateral thyroidectomy for thyroid carcinoma. METHODS Data were extracted from the administrative databases of all hospital discharge abstracts in the Rhône-Alpes area of France. The study population included inpatient stays from 1999 to 2004 with a diagnosis of thyroid disease (benign or malignant) and a procedural code for thyroid surgery. Multivariable logistic regression analyses were performed to determine factors associated with the extent of surgery (unilateral versus bilateral) for thyroid carcinoma. RESULTS A total of 20 140 thyroidectomies were identified, including 4006 procedures for cancer. Compared with hospitals performing a high volume of procedures for all thyroid diseases (at least 100 annually), the risk of a unilateral procedure for thyroid cancer increased by 2.46 (95 per cent confidence interval 1.63 to 3.71) in low-volume hospitals (fewer than ten operations per year) and by 1.56 (1.27 to 1.92) in medium-volume centres (ten to 99 per year). CONCLUSION There is a significant relationship between hospital volume and the decision to perform bilateral surgery for thyroid carcinoma. Thyroid cancer surgery should be performed by experienced surgical teams in high-volume centres.

Abstract
Improvement in Type 2 diabetes is seen in 80-98% of obese diabetic patients who undergo gastric bypass or bilio-pancreatic diversion. This improvement is evident early after the operation before significant weight loss has occurred. Although numerous teams have extensively studied the physiology of this early post-bypass amelioration of type 2 diabetes, the exact mechanism of diabetes remission remains unclear. Studies have focused on changes in the entero-insular axis, which is mediated in part by the interaction of insulinotropic hormones GIP and GIP 1 on the beta islet cells of the pancreas. Other mechanisms which have been postulated focus on the adipo-insular axis; the actions of adiponectin and leptin seem to have an important role in insulin resistance but their action is weight-loss dependent. Post-operative caloric restriction may also contribute to the early resolution of type 2 diabetes observed after gastric bypass and bilio- pancreatic diversion.

Abstract
Abstract
Background
A control chart can help to interpret and reduce sources of variability in patient safety by continuously monitoring indicators. The aim of this study was to monitor the outcome of thyroid surgery using control charts.
Methods
Patients who had thyroid surgery during 2006–2007 were included in the study. Safety was monitored based on postoperative complications of recurrent laryngeal nerve palsy and hypocalcaemia. Indicators were extracted prospectively from the hospital information system and plotted each month on a P-control chart. Performance of the surgical team was also measured retrospectively for 2004–2005 (baseline period) to compare surgical outcomes before and after control chart implementation. Electromyographic monitoring of recurrent laryngeal nerves was not used, nor was calcium or vitamin D given routinely.
Results
The outcomes of 1114 thyroid procedures were monitored. Although the proportion of patients with recurrent laryngeal nerve palsy was similar for baseline and monitored periods (6·4 and 7·2 per cent respectively), there was a 35·3 per cent decrease in hypocalcaemia after implementation of control charts (P < 0·001). Complications almost doubled during a period when one surgeon was away and operating room renovations took place.
Conclusion
Outcome monitoring in thyroid surgery using control charts is useful for identifying potential issues in patient safety.

Abstract
Prognosis of differentiated thyroid cancer is favorable in the majority of cases. However, distant metastases occur in 10-15% of cases, predominantly in lungs and bones, especially in older patients exhibiting poorly differentiated forms or advanced stages. We report a case history of Hürthle cell thyroid carcinoma metastasized to the sigmoid colon. To the best of our knowledge, this location has never been described before. This case history illustrates the difficulties of diagnosis and treatment in patients whose metastases do not concentrate radioiodine. The interest of different imaging modalities, including fluoro-deoxy-glucose positron emission tomography scan and somatostatin receptor scintigraphy, is discussed.

Abstract
Intraperitoneal chemohyperthermia (IPCH) with Cytoreductive surgery (CS) has been used in Centre Hospitalier et Universitaire Lyon Sud (CHLS) since 1989. Up to 2005, 420 patients were involved in different phase II studies for peritoneal carcinomatosis (PC) from colorectal, gastric or ovarian origin, as well as for pseudomyxoma peritonei and peritoneal mesothelioma. Encouraging results were achieved in case of optimal PC cytoreduction. The CHLS experience, as well as the Dutch randomized trial and the international registration, underline the advantage of such an aggressive combined therapy for selected patients in experienced multidisciplinary centers.

Abstract
Rectal syndrome caused by locoregional evolution of low rectal cancers and anal cancers is prevented and treated by surgical resection. But, for old patients with multiple tares, carcinologic surgical resection as abdominoperineal amputation can not be considered. Management of rectal syndrome becomes a therapeutic challenge. We reported a prospective serie of 5 patients more than 80 years old with multiple tares, treated by rectal amputation by pure perineal approach with laparoscopic colostomy. This surgery avoided for all patients trying rectal symptoms and maintained acceptable quality of life with fast coming back at home. The palliative treatment of low rectal cancers or anal cancers combining rectal amputation by pure perineal approach with laparoscopic colostomy may be an interesting therapeutic option for patients who cannot undergoing aggressive carcinologic surgical treatment.

Abstract
OBJECTIVE Soon after its introduction in 1992, laparoscopic adrenalectomy became the gold standard in the surgical management of most adrenal tumors. The aim of this study was to assess the influence of laparoscopy on surgical indications. PATIENTS AND METHODS Between 1994 and 2003, 220 adrenalectomies were performed, 179 among them by a laparoscopic approach. There were 137 females and 83 males. The mean age was 53 years (range 15-83 years). RESULTS The indications of adrenalectomy were: Cushing syndrome 18%, pheochromocytoma 31%, Conn syndrome 16%, incidentaloma 21%, and malignant tumours 13%. Laparoscopic approach was performed in 81% of the cases and the conversion rate was 11%. There were 3 postoperative deaths (2 after laparoscopy). The mean hospital stay was 7.6 days in the laparoscopic group, and 13.6 days in the open surgery group. CONCLUSIONS This study is consistent with the findings of the literature supporting that there are no indications for the open procedure in case of small benign lesions. The video-asisted adrenalectomy had not changed the management of the adrenal incidentaloma. Today, the laparoscopic approach seems to be adapted also for malignant disease.

Abstract
BACKGROUND Significant morbidity can result from perineal wounds, particularly after radiotherapy and extensive resection for cancer. Myocutaneous flaps have been used to improve healing. The purpose of this study was to evaluate the morbidity and results of primary rectus abdominis myocutaneous flap reconstruction of the vagina and perineum after extended abdominoperineal resection. METHODS Thirty-one consecutive patients undergoing one-stage rectus abdominis myocutaneous flap reconstruction of extensive perineal wounds were studied prospectively. Twenty-six patients had surgery for recurrent or persistent epidermoid anal cancer or low rectal cancer, and 21 had high-dose preoperative radiotherapy. RESULTS Three weeks after the operation, complete healing of the perineal wound was seen in 27 of the 31 patients. There were nine flap-related complications including three patients with partial flap necrosis, two with vaginal stenosis, one with vaginal scarring, one with small flap disunion and two with weakness of the anterior abdominal wall. There were no unhealed wounds at the completion of follow-up (median 9 months). CONCLUSION The transpelvic rectus abdominis myocutaneous flap for the reconstruction of large perineal and vaginal wounds achieves wound healing with only moderate morbidity in the majority of patients after extensive abdominoperineal resection with or without radiotherapy.

Abstract
AIM OF THE STUDY The aim of this retrospective study was to propose a therapeutic strategy according to clinic and pathologic presentations, in differentiated thyroid carcinoma in patients less than 20 years of age. PATIENTS AND METHODS From 1995 to 2002, 74 patients less than 20 years of age were operated on for a differentiated thyroid carcinoma. Patients were divided in two groups according to the presence of lymph node (LN) detected before operation (19 "with LN" and 55 "without LN"). RESULTS Surgery consisted of total thyroidectomy and lymph node dissection in the group "with LN". In the second group "without LN", total thyroidectomy was performed in 19 patients (associated with lymph node dissection in seven) and loboisthmectomy in 29 patients. Post operative radio iodine ablation was performed in 25 patients (16 "with LN" and nine "without LN"). During the follow up (median 71 months), 9/19 patients "with LN" underwent surgery for lymph node recurrence. Four patients of the "without LN" group were reoperated for recurrence in the controlateral thyroid lobe after initial loboisthmectomy. Initial presence of lymph nodes was a risk factor for reoperation. Survival without reoperation at 5 and 10 years was 58% and 38% for the "with LN" group and 96% and 91% for the "without LN" group respectively (P < 0.001). At the time of analysis, all patients were alive. Ninety percent of patients were in remission (68% of "with LN" and 98% of "without LN" patients). CONCLUSION The risk of reoperation for lymph node recurrence during first post operative year is important in the "with LN" group. Therapeutic strategy consists of total thyroidectomy, complete lymph node dissection, radio iodine administration and l-thyroxine treatment. In "without LN" patients risk of lymph node recurrence is low. Treatment consist of total thyroidectomy, lymph node dissection and radio iodine administration are not systematic.

Abstract
From 1994 to 2000, 32 patients (16 men, 16 women; mean age 53 years) underwent laparoscopic adrenalectomy at Hôpital l'Antiquaille of Lyon. All but one had systemic arterial hypertension and hypokaliemia was noted in all patients. All patients had unilateral adrenalectomy, and only one required conversion to conventional laparotomy. There were no deaths and complications were rare.

Abstract
BACKGROUND AND AIMS This prospective study compared jejunoileal length in patients with Crohn's disease (CD) and the general population to determine whether this parameter can be related to outcome and management of CD complications. PATIENTS AND METHODS Small bowel (SB) length was measured during abdominal surgery prior to bowel resection in 93 patients with CD and 92 patients without inflammatory or small bowel disease. RESULTS SB length was shown to be shorter in patients with CD (462 vs. 567 cm) and was correlated to sex and height. There was no correlation of SB length to clinical expression (perforating or nonperforating), site, or outcome. SB length is not a prognosis factor of postoperative relapse. The presence of perineal disease and systemic abnormalities seem to be the only prognostic factors of surgical recurrence. Sex, age at onset, time of first surgery, site of disease, and mode of onset are not predictive of surgical recurrence. CONCLUSION We recommend minimal intestinal resection when surgical treating CD complications in patients at high risk of surgical relapse and initial short SB. We advise using stricturoplasty or leaving asymptomatic intestinal lesions to reduce short bowel syndrome occurrence when performing iterative surgery.

Abstract
After an anatomic recall of the cervical lymph node compartments we describe the surgical technique of the lymph node dissection in patients with differentiated thyroid carcinoma. These lymphadenectomies should be associated with total thyroidectomy. Cervical lymph node dissection always concerns central compartment and is sometimes extended to the cervico lateral compartments. Lymphadenectomy of a compartment should be complete, reoperations leading to an important morbidity. The two main complications of cervical lymph node dissection are inferior laryngeal nerve palsy and hypoparathyroidism.

Abstract
STUDY AIM The aim of this retrospective study was to assess our experience of the laparoscopic surgery of pheochromocytoma. We report indications and results of laparoscopic and open adrenalectomy for pheochromocytoma. PATIENTS AND METHODS Between january 1994 and may 2002, 50 patients underwent laparoscopic or open adrenalectomy for pheocromocytoma. The perioperative hemodynamic parameters were assessed for each patient. In each case, urinary metanephrine levels were measured at the second month postoperatively. The long term outcome was assessed in 44 patients. The mean follow-up was 39 months. RESULTS Ten patients underwent open adrenalectomy: 8 patients for unilateral tumors (tumor size was > 8 cm in 7 cases) and 2 patients for bilateral tumors (1 recurrence and 1 cystic polylobed tumor). Fourty patients underwent laparoscopic adrenalectomy: in 32 cases, including 1 patient with a bilateral tumor, no conversion was performed (tumor size was < 5 cm in 29 cases). In 8 cases (20%), a conversion to an open operation was performed. The reasons to convert were bleeding and periadrenal fibrosis in 7 cases. In laparoscopic adrenalectomy group, hemodynamic troubles were not more frequent, the hospital stay was shorter and there was no recurrence. CONCLUSION Laparoscopic adrenalectomy is the Gold standard procedure for patients with pheochromocytoma. But open adrenalectomy is sometimes indicated: tumor size > 8 cm, periadrenal fibrosis, and recurrence tumor.

Abstract
PURPOSE OF THE STUDY Insertion of cement plugs into the femoral shaft has become an essential part of total hip arthroplasty procedures. The goal is to achieve secure cementing of the femoral component, but the pressure induced can cause serious problems. The purpose of this study was to determine the effect of a flexible bioabsorbable cement restrictor with decompression valves on cementing efficacy and to determine the effect of inserting the restrictor then the cement plug into the femoral shaft on respiratory functions. MATERIAL AND METHODS The restrictor was implanted in 108 patients undergoing first-intention total hip arthroplasty. The canal was prepared and calibrated before inserting the restrictor at a depth estimated at preoperative planning to be 10 to 20 mm below the tip of the femoral stem. The efficacy of the restrictor was assessed using radiographic criteria for the quality of the cement sheath and its position relative to the femoral stem. Oxygen saturation of arterial blood and end-expiration PCO2 were measured at first incision, at insertion of the restrictor, at insertion of the cement plug, and at insertion of the femoral stem. RESULTS The relative position of the restrictor was measured on postoperative x-rays at less than 20 mm in 75% of the patients, at 20-40 mm in 13% and at more than 40 mm in 12%. No cement leakage through the restrictor was identified on postoperative x-rays. The quality of the cement sheath was satisfactory in 71% of the patients (77 procedures), fair in 20% (22 procedures) and poor in 8% (9 procedures). For a first group of patients operated on under spinal anesthesia and optional oxygen delivered with a face mask, there was no significant difference in arterial blood oxygen saturation before the procedure and during the four explored operative times. Conversely, in a second group of patients who had general anesthesia without oxygen enrichment of the initial oxygen-nitrogen protoxide gas mixture, arterial blood oxygen saturation during the four operative times was statistically different from the preoperative value. The same observation was made for end-expiratory PCO2. DISCUSSION The retrictor's decompression valves did not allow cement leakage beyond the restrictor. The risk of restrictor migration after insertion and after the increased pressure due to cement plug insertion was not increased and was found to be less than rates reported in the literature. In the patients who had general anesthesia, blood gases showed a minimal, but significant, decrease during the operative times susceptible to induce increased intramedullary pressure. In patients who had a non-cemented acetabular insert, use of the pressure-valve cement restrictor appeared to stabilize these parameters.

Abstract
AIM OF THE STUDY Primary hyperparathyroidism usually affects elderly patients. Juvenile primary hyperparathyroidism is rare, and raises diagnostic and prognostic problems. The aim of this retrospective study on 24 patients is to establish clinical, histological, and therapeutic features of juvenile primary hyperparathyroidism. PATIENTS AND METHODS From 1986 to 2001, 673 patients were treated for primary hyperparathyroidism in our department. Twenty four patients were younger than 30 years old (3.5%). There were 14 women and 10 men. Mean age was 23 year (14-30). Clinical manifestations, pathologics findings and postoperative results were studied. RESULTS Sixteen patients presented a sporadic form of primary hyperparathyroidism with a single adenoma. Clinical manifestations were renal symptoms in 11 cases and acute hypercalcemia syndrome in 2 cases. Seven patients had a NEM I syndrome: parathyroid lesions were 6 hyperplasia and one adenoma. A 27 years old woman presented a recurrent familial isolated hyperparathyroidism. She was operated on 10 years before and at reoperation parathyroid carcinoma was found. Nineteen patients were cured after a post operative follow up ranging from 3 to 168 months. One patient had an asymptomatic hypercalcemia recurrence. Two patients presented permanent hypoparathyroidism treated with calcitriol and calcium. CONCLUSION Sporadic forms represent majority of cases of juvenile hyperparathyroidism. Renal manifestations are usual. Nevertheless, multiple endocrine neoplasia type 1 has to be evocated.

Abstract
STUDY AIM To appreciate the impact of preoperative localization in surgical treatment of insulinomas. PATIENTS AND METHOD From 1986 to 2001, 29 patients were surgically treated for suspected insulinoma. Preoperative imaging assessment was performed in 26 patients: ultrasonography (n = 21), computed tomography (n = 23), endoscopic ultrasonography (n = 13), intraoperative ultrasonography (n = 22) (2 of them under laparoscopic approach). RESULTS The sensibility of the localization procedures was as follows: ultrasonography = 9.6%, computed tomography = 39%, endoscopic ultrasonography = 92.3%, surgical exploration 79.3%, intraoperative ultrasonography 86.3%. The sensibility of intraoperative palpation associated which intraoperative ultrasonography was 100%. Surgical procedures included: 11 enucleations, 10 segmental resections of the tail, 1 left pancreatectomy, 3 median pancreatectomies, 4 subtotal pancreatectomies. There was no postoperative mortality and postoperative morbidity rate was 17%, including 4 pancreatic leakages. Histological examination found solitary tumor in 22 patients (1 of them was a malignant tumor), multiple tumors (MEN 1) in 4 patients and factitious hypoglycemia in 3 patients. All the insulinomas were resected. CONCLUSION Intraoperative evaluation of the pancreas with intraoperative ultrasonography was associated which a right localization in 100% of insulinomas. The place for preoperative imaging seems to be limited. A laparoscopic approach in sporadic insulinomas could modify this attitude.

Abstract
STUDY AIM The aim of this retrospective study was to report results of 21 tracheal or esophageal resections for invasive thyroid carcinomas. PATIENTS AND METHODS Between January 1988 and August 2000, 21 patients (mean age: 66 years) had a tracheal (n = 10) or esophageal (n = 11) resection for involvement by an invasive thyroid carcinoma. There were eight undifferentiated carcinomas, 11 papillary, one follicular and one epidermoid carcinomas. RESULTS One patient died from pulmonary embolism during the postoperative period. Complications were: tracheal fistula (n = 2), tracheal stenosis (n = 1), esophageal fistula (n = 2), recurrent nerve palsies (n = 8) and hypoparathyroidism (n = 4). Seven patients presented local recurrence and seven presented distant metastases. Ten patients were alive and ten patients died of their carcinoma. The mean survival in this study was 26 months (21 months for anaplastic carcinomas and 41 months for differentiated carcinomas). CONCLUSION Differentiated thyroid carcinomas have to benefit from a complete tumoral resection; tracheal or esophageal resection is indicated in case of involvement. Anaplastic carcinomas have a poor prognosis; complete resection is indicated only for selected patients; radiotherapy and chemotherapy are used, because surgery is often impossible.

Abstract
The authors report the fourteenth case of rectourethral fistula associated with Crohn's disease, in a 53-year-old man with a 20-year history of ileocolonic Crohn's disease. The patient developed a rectourethral fistula following an episode of complex anoperineal suppuration surgically exposed on several occasions. Repeated surgical exposure and urine drainage were not sufficient to close the fistula and cure the perineal suppuration. After 10 months, the patient was treated by the rectal mucosal transposition flap technique to close the rectal aspect of the fistula, which ensured cure of the patient's fistula and anoperineal lesions. This technique has been used successfully on 4 occasions and appears to be an effective treatment for rectourethral fistula in Crohn's disease with healthy rectal mucosa.

Abstract
STUDY AIM Oncological complete surgery of retroperitoneal tumours may require segmental resection of part of the invaded inferior vena cava. The aim of this retrospective study was to assess whether reconstruction of the inferior vena cava is necessary and presents any advantage. PATIENTS AND METHODS This study included four patients who underwent partial resection of the inferior vena cava invaded by a retroperitoneal tumour, without reconstruction. Tumours were one renal cancer, one malignant phaeochromocytoma, one malignant retroperitoneal histiofibroma and one undifferentiated retroperitoneal carcinoma. The resection was located at the level of the renal confluence, associated with right nephrectomy, in 3 patients, and above this confluence, at the level of the retrohepatic inferior vena cava in 1 patient. RESULTS Only one case of transient acute renal failure was observed during the postoperative course. One patient developed right deep vein thrombosis after three months and another one after 30 months. One patient died from cancer recurrence after 19 months. The other 3 patients were alive with anticoagulant therapy and without sequelae after 3, 6 and 15 years.

Abstract
The authors report a case of pneumatosis cystoides intestinalis which, after failure of medical treatment, was treated by laparoscopic partial colectomy. Surgical treatment is a last resort and the laparoscopically-assisted approach seems to be a good indication in colectomy for pneumatosis cystoides intestinalis.
