Morbidity of total thyroidectomy for substernal goiter: A series of 70 patients.

Total thyroidectomy for substernal goiter occasionally requires a sternotomy associated with a cervical incision. We sought to analyze the postoperative complications of thyroidectomy for substernal goiters in our center and more precisely the complications related to the sternotomy. All patients who underwent total thyroidectomy for substernal goiter in our center between 2007 and 2016 were reviewed retrospectively. Patients with combined cervical incision and sternotomy (ST group, n=16) were compared to those with cervical incision alone (CT group, n=54), with regard to postoperative complications. Risk factors for the occurrence of postoperative complications were investigated in this population. A total of 24 patients (34.2%) had one or more postoperative complications. The incidence of transient hypoparathyroidism and recurrent laryngeal nerve injury were higher in the ST group (P=0.001 and P=0.052, respectively). The median duration of hospitalization was longer in the ST group (P<0.001). Eighteen patients (25.8%) had a malignant tumor on final pathology. In univariate analysis, the following risk factors for transient postoperative hypoparathyroidism were identified: sternotomy, preoperative symptomatic character and thyroid height (P=0.001, P=0.009 and P=0.013, respectively). In multivariable analysis, only sternotomy was an independent risk factor for postoperative transient hypoparathyroidism (OR=4.48 [1.1; 18], P=0.035). Sternotomy is associated with added morbidity that is not negligible. This surgical approach should be reserved for substernal goiters that descend into the posterior mediastinum, below the level of the aortic arch, when there is suspicion of carcinoma with loco-regional invasion, or when the thyroid tissue is located mainly intrathoracically (conical shaped thyroid, asymptomatic goiter, ectopic thyroid).

[Long-term outcome of neoadjuvant radiochemotherapy followed by surgery for esophageal cancer: a single institution retrospective study of 102 patients]. / Résultats à long terme de la chimioradiothérapie néoadjuvante des cancers de l'œsophage: étude rétrospective monocentrique sur 102 patients.

PURPOSE AND OBJECTIVES: To report survival and morbidity of a large homogeneous cohort of patients with a locally advanced esophageal or cardia carcinoma and put in evidence predictive factors of locoregional control and survival. PATIENTS AND METHODS: Hundred and two patients were treated at the university hospital of Tours between 1990 and 2010 and received neo-adjuvant chemoradiation therapy with external irradiation (40Gy-44Gy) and two courses of chemotherapy (5-fluoro-uracile and cisplatine). Esophagectomy associated with lymph node dissection was performed about ten weeks after the end of chemoradiation therapy. RESULTS: The median follow-up was 22.4 months [6-185 months]. The overall survival rates at 2 and 5years were 53% and 27%, respectively. The median overall survival was estimated at 27months. The overall 2-year survival between patients "responders" and patients "non-responders" was 67% vs 26%, respectively (P<0.0001). In case of histological response, there was a benefit in terms of overall survival (P<0.0001), locoregional control (P<0.0036) and disease-free survival (P<0.001). Overall survival at 2years was 64% for ypN0 group vs 32% for ypN1 group (P<0.0001). The median survival was estimated at 37months against 15months in the absence of lymph node involvement (P<0.0001). CONCLUSION: Our results in terms of survival, tolerance and morbidity and mortality were comparable to those in the literature. Complete histological response of lymph node was associated with an improvement of local control, disease-free survival and overall survival.

Determinants of outcome following laparoscopic peritoneal lavage for perforated diverticulitis.

BACKGROUND: Laparoscopic peritoneal lavage has been proposed for generalized peritonitis from perforated diverticulitis to avoid a stoma. Reports of its feasibility and safety are promising. This study aimed to establish determinants of failure to enable improved selection of patients for this approach. METHODS: The study included all patients with perforated sigmoid diverticulitis who underwent emergency laparoscopic peritoneal lavage from January 2000 to December 2013. Factors predicting failure of laparoscopic treatment were analysed from data collected retrospectively. RESULTS: For patients undergoing emergency sigmoid resection (72 of 361), mortality and morbidity rates were 13 and 35 per cent respectively. In all, 71 patients had laparoscopic lavage, with mortality and morbidity rates of 6 and 28 per cent respectively. Reintervention was necessary in 11 patients (15 per cent) for unresolved sepsis. Age 80 years or more, American Society of Anesthesiologists grade III or above, and immunosuppression were associated with reintervention. CONCLUSION: Elderly patients and those with immunosuppression or severe systemic co-morbidity are at risk of reintervention after laparoscopic lavage.

[Parathyroid carcinoma: multicenter study of 17 patients]. / Carcinome parathyroïdien.

PURPOSE OF THE STUDY: To evaluate clinical characteristics and survival of patients treated for parathyroid carcinoma. STUDY DESIGN: A retrospective multicenter chart review of patients treated for parathyroid carcinoma between January 1979 and January 2005. RESULTS: 17 patients (10 women, 7 men) presenting with parathyroid carcinoma underwent surgical resection. Symptoms were largely related to hypercalcemia. Mean postoperative follow-up was seven years. Local recurrence was noted in four patients (24%) and three patients had late distant metastasis (18%). At the end of the study, nine patients were alive without evidence of recurrence (53%) and one patient was alive with recurrence at 5 years. Seven patients had died, four of whom died as a result of their parathyroid disease. CONCLUSION: Even when symptoms and findings are suggestive, the diagnosis of parathyroid carcinoma is oftentimes difficult. An adequate resection at the first intervention (complete tumor resection including a homolateral thyroid lobectomy and parathyroidectomy with resection of central lymph nodes) is recommended.

[Surgery treatment of rectal cancer]. / Chirurgie du cancer du rectum.

Surgical resection is the only curative procedure for carcinoma of the rectum. Heald's development of total mesorectal excision has made it the standard approach for mobile, non-fixed tumors; it permits optimal local control with less than 10% local recurrence at five years and minimizes nerve damage and genito-urinary complications. Although initial short-term results of laparoscopic approaches are very promising, the final role of laparoscopy has not yet been established. Neo-adjuvant radiotherapy should be proposed for locally advanced (T3, T4, and/or N+) tumors of the low and mid-rectum. Radiochemotherapy coupled with intersphincteric dissection offers hope for sphicter-sparing extirpation of even the lowest of rectal cancers. Local resection through a trans-anal approach may be considered for small (<3 cm.), mobile, well-differentiated tumors lying within 8 cm. of the anal verge if rectal echo-endoscopy shows an in-situ tumor or a T1 lesion with no evidence of lymphadenopathy. Future strategies may enlarge the indications for local resection if and when radiochemotherapy can achieve a complete local response (tumor sterilization).

Central neck dissection in the management of sporadic medullary thyroid microcarcinoma.

AIM: Treatment of medullary thyroid carcinoma (MTC) includes total thyroidectomy with at least bilateral central neck dissection. Systematic measurement of thyrocalcitonin (CT) levels in thyroid nodules allows for early diagnosis of MTC. As central neck dissection (CND) is associated with high morbidity, the aim of this study was to investigate the necessity of this procedure in the treatment of sporadic medullary thyroid microcarcinoma (S-mMTC). METHODS: Prospective multicentric study including 43 patients with sporadic micro-MTC who underwent CND between January 1991 and August 2001. RESULTS: 26 women and 17 men with sporadic micro-MTC, aged 28-87 (mean age was 58 years), without family history of multiple endocrine neoplasia, underwent surgery. Total thyroidectomy was performed in all patients and combined with 'picking' (n=7) or CND (n=36). Size of tumours ranged from 0.2 to 9mm (mean size was 4.1mm). Solitary (32/43 patients) and multiple S-mMTC lesions (11/43 patients) were seen. 601 lymph nodes from the 41 subclinical patients were analysed. Mean follow-up period for these patients was 32 months. No mutations in the RET oncogene were seen. CONCLUSION: As lymph node involvement is uncommon in S-mMTC, systematic CND is of questionable value.

[Local excision of rectal cancer for cure]. / Exérèse locale à visée curative des cancers du rectum.

Local excision of rectal cancer is advocated for cure only in selected patients. It should be done according to specific standards and needs close follow up. The transanal technique is well defined and indicated for posterior rectal wall tumours. Otherwise, technical modifications or microsurgery can be performed. The transacral approach should be abandoned.

[Primary epiploic appendicitis: an etiology of acute abdomen revealed by CT scan]. / Appendicite épiploïque primitive: une étiologie d'abdomen aigu révélée par la tomodensitométrie.

Primary epiploic appendicitis are considered to be a rare cause of acute abdomen. We reported 2 cases in which computed tomography CT suggested the diagnosis. Primary epiploic appendicitis shows characteristic CT findings that allow the diagnosis and follow-up. This entity resolves spontaneously and CT helps in avoiding unnecessary surgery.

[Morbidity and mortality of acute pancreatitis. Prospective study in a French university hospital]. / Morbidité et mortalité de la pancréatite aiguë. Evaluation prospective dans un centre hospitalier universitaire français.

OBJECTIVE: According to certain learned societies, acute pancreatitis mortality should not exceed 10%. The aim of our work was to review the etiology, severity and mortality of acute pancreatitis in a prospective series of patients admitted to a regional university hospital in France, using standardised collection of data assessing the medico-surgical habits in the management of acute pancreatitis. METHODS: From February to September 1999, 86 patients (54 men and 32 women with a mean age of 58.5 years) were admitted for 88 episodes of acute pancreatitis. Data was collected from all the patients on admission and permitted measurement of the severity and prognosis scores and the study of the etiology, complications and management of the latter and the mortality with acute pancreatitis. RESULTS: Ranson's score was a mean of 2.4. Balthazar's score was superior or equal to D in 45% of cases. The respective prevalence of lithiasis, alcoholism, tumors, others or undetermined was of 41%, 37.5%, 7%, 5.5% and 9%. Acute pancreatitis was severe (multi organ failure, pseudo-cyst, systemic or necrotic infection and occlusive syndrome) in 32% of cases. Complications were: infection (22%), pseudo-cyst (14%), pleural effusion (12.5%) and occlusive syndrome (3.5%). Fever of more than 38.5 degrees C was noted in more than half of the patients. The median duration of hospitalisation was of 11 days (range: 1-86 days). Global hospital mortality was of 13.6% (12/88), and of 43% (12/28) in cases of severe acute pancreatitis. Six deaths occurred within the first 8 days of acute pancreatitis, and 6 after 8 days. Seven deaths (59%) were due to multi organ failure, 4 (33%) to infectious causes and one to another cause. CONCLUSION: The standardized collection of clinical and progressive data used in this study permitted assessment of the medico-surgical habits in a regional university hospital.

[Total pancreatectomy for mucinous pancreatic tumor]. / Pancréatectomie totale pour tumeur mucineuse du pancréas.

AIM OF THE STUDY: To report our experience of total pancreatectomy (TP) in ten patients with mucinous pancreatic tumors (MPT), to discuss pre and peroperative investigations in the management of MPT, and operative, functional and carcinologic results after TP. PATIENTS AND METHODS: This retrospective study from January 1985 to January 2001 included ten patients, 5 men and 5 women (mean aged: 64 years). Six patients underwent one step TP for intraductal papillary mucinous tumor of the pancreas (IPMT) in 5 cases, and multifocal mucinous cystadenoma in one case. Four patients underwent a second step TP for tumor recurrence (2 IPMT, and 2 cystadenocarcinomas) which occurred 12 to 121 months post operatively (mean: 49 months). RESULTS: Post TP diabetes was controlled by insulinotherapy (3 injections a day), except in one patient who needed insulin administration through a pump. One patient, with cystadenocarcinoma, died from cancer recurrence 18 months after TP and 140 months after the initial pancreaticoduodenectomy. One patient died from heart disease 34 months postoperatively. The 8 other patients were alive with a mean follow-up of 33 months (range 11-61 months). CONCLUSION: Curative surgery for mucinous tumors of the pancreas may require TP, which is indicated preoperatively according to imaging, or intraoperatively following surgical findings and frozen section of the pancreatic margin. Totalization of a previous partial pancreatectomy is mandatory in case of tumoral persistence or recurrence in the pancreatic remnant. Postoperative diabetes can be managed successfully by a specialized team.

[Laparoscopic fundoplication for gastroesophageal reflux disease: retrospective study of functional results in 243 patients]. / Fundoplicature laparoscopique pour reflux gastro-oesophagien: étude rétrospective des résultats fonctionnels chez 243 patients.

STUDY AIM: The aim of this retrospective study was to evaluate the 38 month-results of laparoscopic fundoplication for gastroesophageal reflux disease (GERD). PATIENTS AND METHODS: Two hundred forty three consecutive patients were operated laparoscopically. The surgical procedures were complete fundoplication with division of short vessels (Nissen: 80 patients), without division of short vessels (Nissen-Rossetti: 68 patients) or partial fundoplication of 270 degrees (Toupet: 95 patients). The mean follow-up was 38 months. Functional results were evaluated in 225 patients (92.5%) using a questionnaire with visual analog scales. RESULTS: The morbidity rate was 5%, higher after Nissen procedure (6.5%). With a follow-up of 3 months: a dysphagia coted 5/10, a gas bloat syndrome coted 4/10 and colon distension present in 61% of patients, were significantly more frequent after Nissen procedure. GERD recurred early in 4.5% of patients. With a follow-up of 38 months: dysphagia rate (coted 1/10) was significantly higher after Nissen. Dysphagia still persisted in 8 patients (9%) after Nissen. Colon distension and flatulence were more present after Nissen fundoplication. GERD recurrence rate was 12%. Pyrosis was significantly higher after Toupet fundoplication. Continuous medical treatment was necessary in 19 patients (8%). The satisfaction of patients was coted 7.5/10 without difference between to the three types of fundoplication. CONCLUSION: The total laparoscopic fundoplication for GERD seems to be a safe and efficient operation. This procedure proves to be more effective than partial fundoplicature but with a grater morbidity. Whatever the type of fundoplicature, the satisfaction of patients was good.

The value of immunoscintigraphy in the detection of recurrent colorectal cancer.

The aim of this prospective study was to determine whether anti-carcinoembryonic antigen (anti-CEA) scintigraphy is a useful additional technique in the diagnosis recurrence of colorectal cancer. Forty patients with suspected recurrence of colorectal cancer, underwent immunoscintigraphy (IS) and helical computed tomography (CT) in the 2 weeks before surgery. Surgical findings were used to evaluate the performance of the imaging techniques. Suspected areas on IS and CT were systematically explored. Helical CT was found to be superior to IS for the liver, the sensitivity and specificity of CT being 100% and 90%, respectively, vs 53% and 100% for IS. However, IS was better than CT for the detection of extra-hepatic abdominal recurrence: sensitivity and specificity of IS were 100 and 82% respectively vs 33 and 82% for CT. Seven cases of peritoneal carcinomatosis were overlooked by helical CT. Our results indicate that IS improves detection of extra-hepatic abdominal recurrence of colorectal cancer. Immunoscintigraphy is valuable as a guide to the treatment strategy and operative procedures.

[Gastric stromal tumor with osteoclast-like multinucleated giant cells during Lynch II syndrome]. / Tumeur stromale gastrique à cellules géantes multinucléées de type ostéoclastique au cours d'un syndrome de Lynch II.

We report an unusual case of gastric tumor: a stromal tumor with osteoclast-like giant cells. This type of cells has been described in epithelial tumors, especially in adenocarcinoma of the pancreas, lung, thyroid and breast. It has also been reported in smooth cell tumors such as uterine leiomyosarcoma and malignant fibrous histiocytoma. In our patient, this gastric stromal tumor with osteoclast-like giant cells was diagnosed in a man with adenocarcinoma of the colon in the context of a familial cancer syndrome. This is the first report of stromal tumor with osteoclast-like giant cells associated with Lynch syndrome.

Multicentre study of thyroid nodules in patients with Graves' disease.

BACKGROUND: The association of Graves' disease with thyroid nodules and thyroid carcinoma is rarely reported. The incidence seems to be increasing according to recent literature. The aim of this multicentre study was to review patients who had surgery for Graves' disease associated with thyroid nodules, and to evaluate the risk of thyroid carcinoma. METHODS: A retrospective study was made of 557 consecutive patients who underwent operation for Graves' disease between 1991 and 1997 in five endocrine surgery departments. Each patient underwent clinical, biochemical, ultrasonographic and scintigraphic evaluation. None of the patients had had previous radioactive iodine therapy or external irradiation. Surgery consisted of either a subtotal or total thyroidectomy. RESULTS: Nodules were observed before operation in 140 patients (25.1 per cent). Thyroid carcinoma was diagnosed in 21 patients (15.0 per cent), always inside a nodule. The incidence of thyroid carcinoma associated with Graves' disease was 3.8 per cent (21 of 557 patients): 20 papillary and one follicular carcinoma. The carcinoma was multifocal in two patients. Tumour diameter ranged from 2 to 25 mm. A nodule was palpable in four patients. CONCLUSION: This multicentre study of patients having thyroidectomy for Graves' disease showed that 3.8 per cent had a carcinoma; the rate of carcinoma in cold nodules was 15.0 per cent. Surgery should be advised in any patient with Graves' disease and a thyroid nodule; the operation should be total thyroidectomy.

Cystadenomas and cystadenocarcinomas of the pancreas: a multiinstitutional retrospective study of 398 cases. French Surgical Association.

OBJECTIVE: To review the features of patients with benign and malignant cystadenomas of the pancreas, focusing on preoperative diagnostic accuracy and long-term outcome, especially for nonoperated serous cystadenomas and resected cystadenocarcinomas. SUMMARY BACKGROUND DATA: Serous cystadenomas (SCAs) are benign tumors. Mucinous cystic neoplasms should be resected because of the risk of malignant progression. A correct preoperative diagnosis of tumor type is based on morphologic criteria. Despite the high quality of recent imaging procedures, the diagnosis frequently remains uncertain. Invasive investigations such as endosonography and diagnostic aspiration of cystic fluid may be helpful, but their assessment is limited to small series. The management of typical SCA may require resection or observation. Survival after pancreatic resection seems better for cystadenocarcinomas (MCACs) than for ductal adenocarcinomas of the pancreas. METHODS: Three hundred ninety-eight cases of cystadenomas of the pancreas were collected between 1984 and 1996 in 73 institutions of the French Surgical Association. Clinical presentation, radiologic evaluation, and surgical procedures were analyzed for 144 operated SCAs, 150 mucinous cystadenomas (MCAs), and 78 MCACs. The outcome of 372 operated patients and 26 nonoperated patients with SCA was analyzed. RESULTS: Cystadenomas represented 76% of all primary pancreatic cystic tumors (398/522). An asymptomatic tumor was discovered in 32% of patients with SCA, 26% of those with MCA, and 13% of those with MCAC. The tumor was located in the head or uncinate process of the pancreas in 38% of those with SCA, 27% of those with MCA, and 49% of those with MCAC. A communication between the cyst and pancreatic duct was discovered in 0.6% of those with SCA, 6% of those with MCA, and 10% of those with MCAC. The main investigations were ultrasonography and computed tomography (94% for SCA, MCA, and MCAC), endosonography (34%, 28%, and 22% for SCA, MCA, and MCAC respectively), endoscopic retrograde cholangiopancreatography (16%, 14%, 22%), and cyst fluid analysis (22%, 31%, 35%). An accurate preoperative diagnosis of tumor type was proposed for 20% of those with SCA (144 cases), 30% of those with MCA, and 29% of those with MCAC. An atypical unilocular macrocyst was observed in 10% of SCA cases. The most common misdiagnosis for mucinous cystic tumors was pseudocyst (9% of MCAs, 15% of MCACs). Intraoperative frozen sections (126 cases) allowed a diagnosis according to definitive histologic examination in 50% of those with SCA and MCA and 62% of those with MCAC. For management, 93% of patients underwent surgery. Nonoperated patients (7%) had exclusively typical SCA. A complete cyst excision was performed in 94% of benign cystadenomas, with an operative mortality rate of 2% for SCA and 1.4% for MCA. Resection was possible in 74% of cases of MCAC. Mean follow-up of 26 patients with nonresected SCAs was 38 months, and no patients required surgery. For resected MCACs, the actuarial 5-year survival rate was 63%. CONCLUSIONS: Spiral computed tomography is the examination of choice for a correct prediction of tumor type. Endosonography may be useful to detect the morphologic criteria of small tumors. Diagnostic aspiration of the cyst allows differentiation of the macrocystic form of SCA (10% of cases) and the unilocular type of mucinous cystic neoplasm from a pseudocyst. Surgical resection should be performed for symptomatic SCAs, all mucinous cystic neoplasms, and cystic tumors that are not clearly defined. Conservative management is wholly justified for a well-documented SCA with no symptoms. An extensive resection is warranted for MCAC because the 5-year survival rate may exceed 60%.
