[Is subtotal bilateral thyroidectomy still indicated in patients with Grave's disease?].
AIM OF THE STUDY: To evaluate the morbidity and the functional results of subtotal bilateral thyroidectomy in patients (TST) with Graves' disease. PATIENTS AND METHOD: A retrospective study was performed in 128 patients. They were 23 males and 105 females with a median age of 34 years (range: 14-68). Weight of remnant tissue was between 4 and 5 g. Thyroid functional status was evaluated, at 3 months and after a follow-up period ranged from 1 to 5 years, by measurement of serum concentration of free T4 and/or free T3 and TSH. RESULTS: They were no post-operative death. Surgical complications were 2 vocal cord palsies and 17 hypocalcemia (inf. to 2 mmol/L). After a median follow-up of 2 years, they were no longer any cases of vocal cord dysfunction and no case of permanent hypoparathyroidism. Functional results were established in 118 patients: 46 patients had clinical hypothyroidism (39%), 64 patients had latent hypothyroidism or euthyroidism (54.2%), and 8 had recurrent hyperthyroidism (6.8%). CONCLUSION: These results suggest that TST with a remnant mass inferior to 5 g provides a low level of recurrent hyperthyroidism and allows to give no drug therapy to half patients. In our opinion, TST is still indicated in Graves' disease.

[Giant parathyroid tumors: characterization of 26 glands weighing more than 3.5 grams].
AIM OF THE STUDY: To determine the characteristics of giant lesions of the parathyroid glands weighting more than 3.5 g. PATIENTS AND METHOD: Twenty-six patients operated on between 1989 to 2001 were included in this retrospective study. Anatomical, biological, clinical and histological parameters were analyzed. Data were compared both with a personnal series of the last 220 patients with hyperparathyroidism operated on in our department and with the results of a primary hyperparathyroidism multicentric study conducted by the French Association of Surgery (AFC). RESULTS: They were 14 females and 12 males with a mean age of 58.57 +/- 13.72 years (ranged: 26-80). Mean weight of the parathyroid glands was 9.87 +/- 9.76 g (ranged: 3.5-40). The diagnosis of parathyroid disease was suspected by symptoms and incidentally discovered hypercalcemia in 17 and 8 cases respectively. In one case, the adenoma was misdiagnosed as a thyroid nodule. Mean calcemia was 125.42 +/- 19.6 mg/L, mean phosphoremia was 21.6 +/- 6.9 mg/L, mean seric parathormone concentration was 451.44 +/- 530.18 ng/L. Comparing with our personnel 220 HPT-series, they was no statistically difference concerning the mean age, but number of males and biological measurements were significantly higher in presence of a giant adenoma. Comparing with the study of the AFC group, there was no statistically difference concerning the symptoms, especially in regard to the asymptomatic forms discovered by hypercalcemia and to the acute hypercalcemia forms. Minor ectopic localizations were found in half of the cases. All the glands were considered as beginnings. After surgery, one patient had a severe hypocalcemia in relation to a hungry bone syndrome. CONCLUSION: Giant adenomas have no specific symptoms even if functional status seems to be more active. Diagnosis is made during the sixth decade as usual. Male people are more often concerned. At surgery ectopic localizations are present in 50% of the cases. In our study their size is not a sign of malignancy. After surgery severe hypocalcemia can occur if a long past of bone disease exists.

[The "pneumoneck" in videocervicoscopy: operative technique and anatomic limits].
The aim of this study was to describe a technic in order to create a gas space "pneumoneck" during videoendoscopic surgery of the neck and to determine the anatomical limits of this space. Data were based on a surgical experience and on the dissection of two corpses. This space was located between the two layers of the pre-tracheal lamina of the cervical fascia. This space was enclosed and favourable to detachment with insufflated gas without subcutaneous emphysema. This approach can be used for parathyroid and thyroid surgery.

[Multiple endocrine neoplasia type I or Werner syndrome. What is important to know about surgery of a rate disease].
Multiple endocrine neoplasia type 1 (MEN1) is a rare but misleading disease. The diagnosis is evocated when two main lesions are present (parathyroid, endocrine pancreas, pituary gland) but also when a family tree shows recurrent lesions. Other lesions must be taken into account (adrenal glands, neuroendocrine thymic or bronchic lesions, cutaneous lesions, lipomas, nervous central system tumors). Any surgical cure without knowing the MEN1 background leads to failure. Specific treatment of each lesion is reviewed. Genetic diagnosis is possible but the mutation is not found in all cases. Nevertheless, when the mutation is known in a family, a negative genetic test allows to exclude the disease. Prognosis is related to hepatic metastases and to thymic neuroendocrine tumors which are rare (2.1%) but aggressive. As a general rule, any apparently isolated endocrine lesion such hyperparathyroidism must prompt the surgeon to look for another endocrine lesion and to look for an abnormal family tree with recurent monoglandular or pluriglandular lesions.

[Recurrent fatal pseudomembranous colitis].
BACKGROUND: Clostridium difficile pseudomembranous colitis may trace a fulminent course and require surgery. CASE REPORTS: Outcome was fatal despite subtotal colectomy in the reported case of recurrent Clostridium difficile pseudomembranous colitis. Infrequent localization, low serum albumin and an unfavorable clinical course were observed. DISCUSSION: Rapid surgical treatment with large resection is mandatory in such cases, particularly in patients of rectal and sigmoid remnant involvement.

Lateral approach to laparoscopic repair of left diaphragmatic ruptures.
Video-assisted repairs of traumatic diaphragmatic ruptures have been described where thoracoscopy or laparoscopy in the supine position were used. This study aims to validate a new lateral laparoscopic approach for left diaphragmatic repairs. Six consecutive patients were operated on for left diaphragmatic rupture using a lateral approach (Gagner's position). A series of 362 consecutive patients presenting with abdominal or thoracic trauma with or without diaphragmatic rupture over a 2-year period were reviewed retrospectively. Contraindications for immediate or delayed lateral laparoscopic approach were studied. The lateral approach provided complete visibility of the subdiaphragmatic space, easy reduction of herniated organs, easy thoracic inspection and cleaning, the use of low peritoneal pressure, full range of instrumental motion, and rapid diaphragmatic repair. No operative mortality or morbidity was noted. Altogether, 14% to 50% of the patients with diaphragmatic ruptures were candidates for immediate lateral laparoscopic repair. Associated spleen injury in 50% of the cases was the main contraindication. The lateral laparoscopic approach provides better exposure of the diaphragm on the left side and facilitates the diaphragmatic repair especially with a large herniation. Immediate repair is possible in selected cases (14-50%). There is no contraindication in case of delayed diagnosis.

Hyperparathyroidism in multiple endocrine neoplasia type I: surgical trends and results of a 256-patient series from Groupe D'etude des Néoplasies Endocriniennes Multiples Study Group.
The French and Belgian GENEM study group's multiple endocrine neoplasia type I (MEN-I) database was used to evaluate trends in clinical presentation, surgical treatment of primary hyperparathyroidism (pHPT) (n = 245), and prognostic factors for hypercalcemia correction among 256 MEN-I cases. The patients were retrieved through the GENEM network from various Belgian and French institutions with the help of genetics laboratories. Among the 245 pHPT patients (96%), 42% were men. The mean age at the time of diagnosis was 39.5 +/- 13.3 years. Trends were studied for three periods: before 1986, from 1986 to 1990, and thereafter. After 1990 MEN-I patients were more often diagnosed with isolated pHPT (8%, 11%, 28%, for the three periods, respectively; p = 0.002); it was seen more often in screened patients (31%, 28%, 53%; p = 0.001), more often among those in already known MEN-I families (64%, 45%, 72%; p = 0.005), and among those with lower preoperative calcemia (2.93, 2.87, 2.79 mmol/L; p = 0.001). The age at pHPT diagnosis remained constant throughout the study. The percentage of cervical explorations dropped during the entire study (87%, 87%, 53%; p < 0.0001). After 1985 the percentage of subtotal parathyroidectomies increased (25%, 59%, 51%; p = 0.0004). Pathology disclosed more hyperplasias (59%, 85%, 74%; p = 0.008). Postoperative hypercalcemia decreased (47%, 15%, 19%; p < 0.0001); and postoperative hypocalcemia increased nonsignificantly (5%, 15%, 15%; p = 0.1). Subtotal parathyroidectomy [odds ratio (OR) 13], no MEN-I family background (OR 3), and the most recent study period (> 1985) (OR 3) were significant predictive factors of hypercalcemia correction according to the multivariate analysis. This is the first multicentric study on the management of MEN-I-related pHPT. Immediate postoperative hHPT cure increased, but only 80% of the operated patients were cured after 1990. Fifteen percent were hypocalcemic. Because MEN-I-related hHPT cure remains difficult to achieve, we advocate that subtotal parathyroidectomies be performed in specialized centers.

Adrenocortical carcinomas: surgical trends and results of a 253-patient series from the French Association of Endocrine Surgeons study group.
Because of the rarity of adrenocortical carcinoma, survival rates and the prognosis for patients who have undergone operation are not well known. The purpose of the French Association of Endocrine Surgery was to evaluate these factors over an 18-year period. A trend study was associated to assess changes in the clinical and biochemical presentations as well as the surgical evolution. A total of 253 patients (158 women, 95 men) with a mean age of 47 years were included. Cushing syndrome was the main clinical presentation (30%), and hormonal studies revealed secreting tumors in 66% of the cases. Altogether, 72% (n = 182) of patients underwent resection for cure, and 41.5% (n = 105) of them had an extensive resection because of metastatic cancer. A lymphadenectomy was performed in 32.5% (n = 89) of the cases. The operative mortality was 5.5% (n = 14). Patients were given mitotane as adjuvant therapy in 53.8% of the cases (n = 135). The results of staging were stage I in 16 patients (6.3%), stage II (local disease) in 126 patients (49.8%), stage III (locoregional disease) in 57 patients (22.5%), and stage IV (metastases) in 54 patients (21.3%). Neither tumor staging nor the rate of curative surgery changed during the study period. More subcostal incisions were performed, and the use of mitotane increased significantly. The 5-year actuarial survival rates were 38% overall, 50% in the curative group, 66% for stage I, 58% for stage II, 24% for stage III, and 0% for stage IV. Multivariate analysis showed that mitotane benefited only the group of patients not operated on for cure. A better prognosis was found in patients operated on after 1988 (p = 0.04), in those with precursor-secreting tumors (p = 0.005), and in those at local stages of the disease (p = 0.0003). Thus mitotane benefited only patients not operated on for cure. Curative resection, precursor secretion, recent diagnosis, and local stage were favorably associated with survival.

[Acute pancreatitis after bilateral laparoscopic adrenalectomy in patients with ectopic ACTH syndrome].
Two cases of acute necrotizing pancreatitis after bilateral laparoscopic adrenalectomy were observed in patients with an ectopic ACTH syndrome. Two reasons may be suspected: the difficulty of dissection in such patients and the specific morbidity in relation to hypercorticism.

[Videoendoscopic approach for parathyroid adenomas: results of a prospective study of 100 patients].
STUDY AIM: The aim of this prospective study was to report the results of 100 consecutive video-endoscopic parathyroidectomies in patients suspected of having a single adenoma. PATIENTS AND METHOD: From March 1997 to September 2000, 80 females and 20 males (mean age: 49.5 years) were operated on. They were selected on the basis of the following criteria: preoperative imaging in favour of a single adenoma, absence of goiter and no prior neck dissection. The technique required three trocars; one 5 mm trocar inserted through the middle line of the neck for the 0-degree 5 mm endoscope, and two 3 mm trocars inserted laterally in order to perform a bilateral exploration. The neck was inflated to 10 mm Hg pressure with a low flow (3 L/min). RESULTS: Exploration was unilateral, bilateral and interrupted respectively in 52, 45 and 3% of the cases. The reasons for stopping were: an incidentally discovered thyroid carcinoma; moderate bleeding occurring from an anterior jugular vein after introduction of a lateral trocar; and a too-short neck. Parathyroid abnormalities were found in 86% of the patients (84 single adenomas, one double adenoma, one hyperplasia of the four glands). In 14% of the cases, the exploration was unsuccessful. A horizontal cervicotomy was required in 15% of the cases (14 negative explorations and one hyperplasia of the four glands). No intraoperative or postoperative complications occurred. The mean hospital stay was 24 hours. After 3-month follow-up, the serum calcium level was normal in 96% of the cases and cosmetic results were excellent. CONCLUSION: A video-endoscopic approach for parathyroidectomy is feasible and safe. With sufficient experience, a bilateral and complete exploration of the neck is possible. Therefore this technique represents a good alternative to the traditional cervicotomy in patients with uniglandular disease.

Characteristics and evolution of extraintestinal manifestations associated with ulcerative colitis after proctocolectomy.
AIMS: Describe the characteristics of extraintestinal manifestations complicating ulcerative colitis present preoperatively and determine their evolution after surgery. METHODS: Between 1976 and 1986, 281 patients with ulcerative colitis exhibiting one or more extraintestinal manifestations (EIM) before either IPAA (n = 147), Brooke ileostomy (n = 71), Kock pouch (n = 48) or ileorectostomy (n = 15) were assessed retrospectively. The clinical evolution of each manifestation was classified as having disappeared, improved, remained unchanged or aggravated postoperatively. An efficacy index was designed to assess the ratio of the number of cases cured or improved over the number of cases unchanged or aggravated. The relationship between EIM and gender, age, duration of disease and the type of surgery was also ascertained. RESULTS: 433 EIM were observed in 281 patients. The most common were arthralgias of the large joints (n = 146), of the sacroiliac joint (n = 59) and the small joints (n = 51). In comparison to patients without EIM having received the same operation during the same period of time, EIM were seen more often in women, younger patients, than those with longer duration of disease and the ileoanal anastomosis group. 60% had only one EIM at a time. Based on the efficacy index, thromboembolic accidents and erythema nodosum were the most commonly cured or improved. Ocular manifestations and primary sclerosing cholangitis were unaffected. The other EIM responded favorably but variably with improvement in two thirds of patients. The presence of a rectal remnant (IRA) or ileal reservoir did not affect the evolution of the EIM. CONCLUSIONS: Thromboembolic complications which are life-threatening, erythema nodosum and arthralgia of the small and large joints which impair quality of life, benefited the most from proctocolectomy. Those conditions may be considered preoperatively when making the decision for surgery.

[Treatment of perforated duodenal ulcer by laparoscopy. 35 cases].
OBJECTIVE: Laparoscopic treatment of perforated duodenal ulcer is an alternative to laparotomy. We reviewed our experience to determine feasibility and reliability of the surgical procedure and the subsequent morbidity and mortality. PATIENTS AND METHODS: This was a retrospective series of 35 patients who underwent laparoscopic repair of perforated duodenal ulcers between January 1994 and November 1999. The perforation was closed by interrupted sutures in 86% of cases associated with irrigation-suction of the abdominal cavity. RESULTS: Two complications were observed: pyloric stenosis in one patient with a large perforation and Douglas pouch abscess in another. Conversion to laparotomy was necessary in 8 cases: in 2 of them the edges of the perforation were fragile, in 3 the perforation could not be identified (posterior position), and in 3 intraabdominal adhesions were important. There were no deaths. The 2-year results are quite satisfactory. CONCLUSION: This study shows that the laparoscopic procedure is reliable and adapted to treat ulcer perforation if the size is less than 1 cm.

[Insulinomas in multiple endocrine neoplasia type 1. Report of a series of 44 cases by the multiple endocrine neoplasia study group].
STUDY AIM: The aim of this retrospective study conducted by the "Groupe d'étude des néoplasies endocriniennes multiples type 1" (GENEM) was to report a series of insulinomas associated with multiple endocrine neoplasias type 1 (NEM 1) and to determine the most appropriate strategy for the topographical exploration and surgical management. PATIENTS AND METHODS: From 1960 to 1996, 44 patients were included, 16 men and 28 women (mean age: 36.4 +/- 13.9 years). This study concerned morphological investigations, tumoral features, modalities and results of the treatment. RESULTS: Insulinomas were associated with other functional islet tumors in 15 patients: ZE syndrome (n = 8), glucagonoma (n = 6), vipoma (n = 1). Malignant lesions were present in 6 patients: isolated insulinomas (n = 2), insulinomas associated with ZE syndrome (n = 2) and vipoma (n = 1). The sensitivity of the preoperative imaging procedures was less than 70%. Fourty-one patients were operated on: subtotal pancreatectomy (n = 26 including cephalic enucleations in 8), enucleations (n = 8), total pancreatectomy (n = 3), pancreaticoduodenectomy with caudal enucleations (n = 1), and for 3 patients, no details were available. There was no postoperative mortality. Hyperinsulinism disappeared in 27 patients (including 2 after reoperation) with a mean follow-up of 9 years. Among 6 patients with malignant lesions, 3 were alive with a 3, 4 and 10 year-follow-up. CONCLUSION: Subtotal pancreatectomy with splenic conservation and enucleation of cephalic lesions is suggested as the procedure of choice in this group of patients. This procedure allows simplification of preoperative imaging investigations because lesions of the pancreatic head have only to be detected. Preoperative endoscopic ultrasonography and intraoperative ultrasonography are the best investigations.

[Treatment of diaphragmatic ruptures by laparoscopic approach in the lateral position].
STUDY AIM: The aim of this retrospective study was to assess the feasibility of the treatment of recent diaphragmatic ruptures through laparoscopic approach in lateral position in patients with stable hemodynamic condition. PATIENTS AND METHOD: From 1994 to 1999, seven patients, 16 to 68 years old, were operated on for diaphragmatic rupture after a 6 hours to 15 days delay. Diaphragmatic rupture was located on the left side in 6 patients, on the right side in 1. Diagnosis was confirmed by CT-scan with reconstructions; there was no associated visceral injury. Patients were operated on by laparoscopic approach in lateral position, herniated viscera reintegrated by moderate pulling and diaphragmatic rupture repaired with non resorbable continuous suture. RESULTS: Stomach was the usual herniated viscera (n = 6); hemothorax was less than 300 cL; diaphragmatic rupture was 8 to 12 cm long. Duration of surgery was no more than 120 minutes. The seven patients after a two months to two years delay had normal chest X-rays. CONCLUSION: The laparoscopic approach in lateral position provides good visibility of the diaphragmatic lesions, easy reduction of herniated organs, complete thorax exploration and cleaning, and easy diaphragmatic repair. This technique is only feasible in patients with stable hemodynamic conditions and does not provide a complete abdominal exploration.

[Repair of midline incisional hernias using the Lazaro da Silva aponeuroplasty technique].
STUDY AIM: The aim of this retrospective study was to assess Lazaro da Silva's rectus sheath aponeuroplasty technique for repair of midline incisional hernias situated above the arcuate line. PATIENTS AND METHOD: Twenty-six patients underwent surgical repair of a supraumbilical (n = 19) or periumbilical (n = 7) incisional hernia. Six patients had had repeated laparotomies and two of them had recurrent incisional hernia. There were 11 obese patients (42%). Muscle diastasis ranged from 4 to 20 centimeters (mean: 9.7 cm). Three overlapping aponeurotic and peritoneal layers were used. The peritoneal sac was partially or totally incorporated in the repair. RESULTS: There was one postoperative death at day 5 from acute pancreatitis in a patient with associated cholecystectomy. Postoperative complications occurred in six patients. There were 3 abdominal wall infections. Obesity was the main factor associated with operative complications (p = 0.03). Mean follow-up was 19.1 months. There were 2 recurrences, one of them related to an abdominal wall infection. CONCLUSION: The Lazaro da Silva aponeuroplasty technique compares favourably with alternative techniques using mesh implants. It is indicated for incisional hernias less than 20 centimeters wide, situated above the arcuate line.

Primary hyperparathyroidism with normal serum intact parathyroid hormone levels.
To evaluate the features of primary hyperparathyroidism (HPT) with normal serum intact parathyroid hormone (iPTH) levels, we studied 271 consecutive patients undergoing surgery for primary HPT. In 20 patients, serum iPTH levels were within the normal range (10-65 ng/l). In their records, the most common clinical features were fatigue (n=13), polyuria (n=6), renal stone (n=5), and hypertension (n=5). Mean serum calcium and phosphorus were 2.78 and 0.85 mmol/l, respectively: 14 had serum phosphorus within the normal range. Mean serum iPTH was 48.5 ng/l, and was <45 ng/l in nine patients. Cervical ultrasound demonstrated a parathyroid adenoma in nine, and was normal in four. Tc sestamibi parathyroid scintigraphy always demonstrated an adenoma (9/9). In eight patients, normal iPTH values delayed diagnosis. Physicians should be aware of the possibility of HPT in patients with hypercalcaemia, even when serum phosphorus and iPTH levels are within the normal limits. Particularly, HPT cannot be excluded when serum iPTH levels are below the upper part of the normal range. In such cases, cervical imaging, which has the same sensitivity as in other HPT, should be undertaken. These explorations are useful, because many patients are symptomatic and can take advantage of surgery.
