Abstract
BACKGROUND Popliteal artery aneurysms (PAA) were traditionally treated by open repair (OR). Endovascular repair (ER) has become a new treatment strategy. The aim of this systemic review and meta-analysis was to evaluate and compare the current outcomes of OR and ER in the emergency treatment of PAA. METHODS A systematic literature search of the PubMed/Medline database was carried out. Outcomes were 30-day mortality, morbidity, major amputation rate (30 days), major amputation rate (1 year), 1-year primary patency rate, 1-year secondary patency rate and 1-year survival. Additionally, we included clinical data of patients with popliteal aneurysms treated between 2009 and 2021 at the Martin-Luther University Halle-Wittenberg. RESULTS We identified two cohort studies from 2014 and 2015 with a total of 199 patients that underwent emergent surgery (39 ER and 160 OR). We also included 26 patients from our institution. For emergency treatment, 30-day major amputation rates (18% vs 3%, Odds Ratio 5.82, 95% CI [1.75; 19.30], p = .004), 30-day mortality rates (10% vs 1%, Odds Ratio 5.57, 95% CI [1.01; 30.58], p = .05), 1-year major amputation rates (15% vs 6% Odds Ratio 3.61, 95% CI [1.18; 11.09], p = .02), 1-year loss of primary patency (54% vs 23%, Odds Ratio 3.19, 95% CI [0.91; 11.20], p = .07), and 1-year loss of secondary patency (44% vs 12%, Odds Ratio 6.91, 95% CI [3.01; 15.83], p < .05) were higher in the ER group when compared to the OR group. CONCLUSION Endovascular repair represents an alternative approach for the emergency treatment of PAA. Limited evidence from the available non-randomized studies shows unfavorable outcomes for patients undergoing ER. However, the results are prone to selection bias, and only randomized trials comparing ER to OR might reveal whether a subgroup of patients would benefit from ER as primary treatment of PAA in an emergency setting.

Abstract
This meta-analysis examines the outcomes of patients undergoing surgery with vascular resection for retroperitoneal sarcoma. A systematic literature search based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted, identifying five comparative retrospective cohort studies published from 2015 to 2021, with a total of 1,417 patients (180 in the vascular resection (VR) group and 1,237 in the control (no VR) group). The meta-analysis found that 30-day morbidity rates, as classified by Clavien-Dindo classification > 3, were higher in the VR group compared to the no VR group (46% versus 25%, odds ratio (OR): 1.84, 95% confidence interval (CI): 0.39-8.69, p=0.44). Local recurrence rates during the follow-up period were similar between the two groups (30% versus 30%, OR: 1.46, 95% CI: 0.50-4.25, p=0.49). However, distant recurrence was more frequent in the VR group (32% versus 8.5%, OR: 2.54, 95% CI: 1.05-6.13, p=0.04). In conclusion, although oncovascular procedures are feasible for patients with retroperitoneal sarcomas, the long-term outcomes appear to be worse when compared to procedures that do not involve vessel resections.

Abstract
BACKGROUND The aim of this study was to analyze the outcome of emergency thoracic endovascular aortic repair (TEVAR) in the treatment of "primary aortic" (aneurysm, aortic dissection, penetrating aortic ulcer (PAU)) and "secondary aortic" (iatrogenic, trauma, and aortoesophageal fistula) pathologies. METHODS Retrospective review of a cohort of patients treated at a single tertiary referral center from 2015 to 2021. The primary end point was postoperative in-hospital mortality. Secondary end points were the duration of the procedure, duration of postoperative intensive care treatment, length of hospital stay, and the nature and severity of postoperative complications according to the Dindo-Clavien classification. RESULTS A total of 34 patients underwent TEVAR for emergency indications. Twenty-two patients were treated for primary and twelve patients for secondary aortic pathologies. Concerning in-hospital mortality, no statistically significant difference could be observed between the primary and secondary aortic groups (27.3% vs. 33.3%, p = 0.711). Patients with an aortoesophageal fistula had a mortality rate of 66.7%. Postoperative morbidity (Dindo-Clavien > 3) was also not statistically significantly different between the primary and secondary aortic groups (36.4% vs. 33.3%, p = 0.86). Preoperative hemoglobin level (p < 0.001 for mortality, p = 0.002 for morbidity), hemoglobin level difference (p = 0.022, p = 0.032), postoperative creatinine level (p = 0.009, p = 0.035), and pre- and postoperative lactate levels (p < 0.001 for both mortality and morbidity) were found to be independent factors associated with postoperative mortality and morbidity (Dindo-Clavien > 3), respectively. The preoperative creatinine level was found to be associated with mortality (p = 0.024) but not morbidity. CONCLUSIONS Morbidity and in-hospital mortality are still considerable after emergency TEVAR for both primary and secondary aortic indications. Pre- and postoperative levels of hemoglobin, creatinine, and lactate may be valuable to predict patient outcomes.

Abstract
The aim of the present study was to analyze the outcome of open surgical and endovascular interventions for the treatment of visceral aneurysms. A retrospective review of a cohort of visceral aneurysm patients treated at a single tertiary referral center was conducted. STROBE guidelines were followed. The primary endpoint was postoperative in-hospital mortality. Secondary endpoints were major morbidity (Dindo-Clavien score, >3), the duration of the procedure, technical success and the length of hospital stay. As a result, 12 patients underwent open or endovascular surgery. No 30-day mortality or major morbidity were observed. The median aneurysm diameter was 2.0 cm (range, 1.5-5.0 cm). The median postoperative stay was four days for all procedures and significantly longer after open surgery compared with endovascular repair (ER) (7 vs. 3 days). Overall, the evidence from the present retrospective analysis shows no mortality and a shorter length of stay for patients undergoing ER for the treatment of a visceral aneurysm (VAA). Although the results are in line with the fact that ER is considered to be the first line treatment for VAA, this may be prone to selection bias.

Abstract
Objectives: To analyze the association of tumor volume with outcome after surgery for cervical paraganglioma. Materials and Methods: This retrospective study included consecutive patients undergoing surgery for cervical paraganglioma from 2009-2020. Outcomes were 30-day morbidity, mortality, cranial nerve injury, and stroke. Preoperative CT/MRI was used for tumor volumetry. An association between the volume and the outcomes was explored in univariate and multivariable analyses. A receiver operating characteristic (ROC) curve was plotted, and the area under the curve (AUC) was calculated. The study was conducted and reported according to the STROBE statement. Results: Volumetry was successful in 37/47 (78.8%) of included patients. A 30-day morbidity occurred in 13/47 (27.6%) patients with no mortality. Fifteen cranial nerve lesions occurred in eleven patients. The mean tumor volume was 6.92 cm3 in patients without and 15.89 cm3 in patients with complications (p = 0.035) and 7.64 cm3 in patients without and 16.28 cm3 in patients with cranial nerve injury (p = 0.05). Neither the volume nor Shamblin grade was significantly associated with complications on multivariable analysis. The AUC was 0.691, indicating a poor to fair performance of volumetry in predicting postoperative complications. Conclusions: Surgery for cervical paraganglioma bears a relevant morbidity with a particular risk of cranial nerve lesions. Tumor volume is associated with morbidity, and MRI/CT volumetry can be used for risk stratification.

Abstract
BACKGROUND Endovascular aortic repair is considered the standard procedure in treating patients diagnosed with pathologies of the abdominal aorta with suitable anatomy. Open surgery remains an option mostly for patients not suitable for endovascular surgery. Colonic ischemia is an important and life-threatening postoperative complication of these procedures. OBJECTIVE The aim of this study is to evaluate the clinical value and safety of performing a planned sigmoidoscopy and biopsy for detection of colonic ischemia in patients undergoing elective aortic surgery. We also aim to develop prediction scores which could identify patients at risk for colonic ischemia and facilitate their timely treatment. METHODS The trial is designed as a prospective study. The decision for aortic surgery and eligibility for these procedures will be ascertained according to current guidelines. Afterward, screening of the patient for the remaining inclusion and exclusion criteria will occur. If eligibility for study inclusion is confirmed, the patient will be informed about the aims of the study and all study-specific procedures (sigmoidoscopy and biopsy) and asked to provide informed consent. RESULTS The primary end point is the proportion of patients diagnosed endoscopically with subclinical and clinically relevant colonic ischemia among all patients undergoing aortic surgery. Patient recruitment started on June 2021. The final patient is expected to be treated by the end of June 2023. Institutional Review Board review has been completed at the University of Halle (Saale; reference #052-2021). CONCLUSIONS this shows that sigmoidoscopy can be performed safely and is effective for the timely diagnosis of colonic ischemia in these patients, this could result in its routine implementation in both elective and emergency settings.

Abstract
BACKGROUND With the advances in multimodality treatment, an analysis of the outcome of arterial resections (AR) in surgery of cholangiocarcinoma is lacking. The aim of this meta-analysis was to summarize the currently available evidence onof AR for the treatment of cholangiocarcinoma. METHODS A systematic literature search was carried out according to PRISMA guidelines. RESULTS 10 retrospective cohort studies published from 2007 to 2020 with 2530 patients (408 AR group and 2122 control group) were identified. Higher in-hospital mortality rates (6.8% vs 3.3%, OR 2.65, 95% CI [1.27; 5.32], p = 0.009), higher morbidity rates (Clavien-Dindo classification ≥3 ) (52% vs 47%, OR 1.44, 95% CI [1.02; 1.75], p = 0.04) and lower 1-year, 3-year and 5-year survival rates (54% vs 69%, OR 0.55, 95% CI [0.34; 0.91 p = 0.02), (34% vs 38%, OR 0.74, 95% CI [0.55; 0.98, p = 0.03), (18% vs 29%, OR 0.54, 95% CI [0.39; 0.75, p = 0.0002) were observed in the AR group when compared to the control group. CONCLUSION Evidence from non-randomized studies shows a higher morbidity and mortality and shorter long-term survival in patients undergoing AR. However, the results are prone to selection bias, and only randomized trials comparing AR and palliative treatments AR might reveal a possible benefit of AR.

Abstract
Abstract
Background
The aim of the study was to analyse the outcome of open surgical, endovascular, and hybrid interventions in the treatment of acute (AMI) and chronic (CMI) mesenteric ischemia.
Methods
Retrospective review of a cohort of mesenteric ischemia patients at a single tertiary referral center from 2015 to 2021. Primary end point was postoperative in-hospital mortality. Secondary end points were the number of bowel resections, duration of the procedure, length of postoperative intensive care treatment, length of hospital stay, revision surgery (number and type), and the nature and severity of postoperative complications according to Dindo-Clavien.
Results
A total of 64 patients, 20 with CMI and 44 with AMI, underwent open, hybrid or endovascular surgery. Bowel resection was performed in 45.5% of the patients with AMI (29.5% small intestine, 2.3% colon and 13.6% both). There was no in-hospital mortality in the CMI cohort as compared to 29.5% in the AMI cohort (p = 0.03), with no differences regarding endovascular and open surgery (29.6 vs 29.4%). Severe postoperative morbidity (Dindo-Clavien ≥ 3) was also significantly more frequent in the AMI group when compared to the CMI group (20 vs 77.3%, p < 0.001). ASA classification and intensive care stay were identified as factors associated with mortality in AMI patients.
Conclusions
Morbidity and in-hospital mortality are low in CMI patients, but substantial in AMI patients. Early diagnosis and open or endovascular treatment may be decisive for the outcome of these patients.

Background In light of recent advances in multimodality treatment, an analysis of vascular resection outcomes in surgery for hilar cholangiocarcinoma is lacking. Objective The aim of this meta-analysis is to summarize the currently available evidence on outcomes of patients undergoing arterial resection for the treatment of hilar cholangiocarcinoma. Methods A systematic literature search in the databases PubMed/MEDLINE, Cochrane Library, and CINAHL, and the trial registries ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform will be carried out. Predefined outcomes are mortality (100-day and in-hospital), morbidity (Clavien-Dindo classification, any type of complication), vascular complications (thrombosis or stenosis of the portal vein or hepatic artery, pseudoaneurysms), liver failure, postoperative bleeding, duration of surgery, reoperation rate, length of hospital stay, survival time, actuarial survival (2-, 3-, and 5-year survival), complete/incomplete resection rates, histologic arterial invasion, and lymph node positivity (number of positive lymph nodes and lymph node ratio). Results Database searches will commence in December 2020. The meta-analysis will be completed by December 2021. Conclusions Our findings will enable us to present the current evidence on the feasibility, safety, and oncological effectiveness of surgery for hilar cholangiocarcinoma with arterial resection. Our data will support health care professionals and patients in their clinical decision-making.

Abstract
PURPOSE To prospectively evaluate the efficacy and safety of a new ethylene vinyl alcohol (EVOH) copolymer-based embolic agent in the treatment of symptomatic peripheral arteriovenous malformations (AVMs). MATERIALS AND METHODS This prospective single-center study evaluated EVOH embolization with 3 different formulations of EVOH (Squid Peri 12 cP, 18 cP, and 34 cP; BALT Germany GmbH, Düsseldorf, Germany) in patients with symptomatic AVMs. Between April 2018 and October 2019, 36 embolization procedures in 21 patients (3 males and 18 females; mean age, 34.7 years) were performed (inclusion criteria: symptomatic peripheral AVM, ≥14 years of age, and elective embolization). Symptoms, technical aspects (transarterial, transvenous, or percutaneous approach; plug or balloon occlusion), clinical and technical success (defined as the improvement of symptoms and complete angiographic eradication of the AVM nidus), adverse events, and short-term outcomes were assessed. RESULTS The mean volume of the embolic agent used per session was 3.4 mL of EVOH 34 cP (standard deviation [SD], ± 5.4), 6.2 mL ± 8.1 of EVOH 18 cP, and 4.6 mL ± 10.1 of EVOH 12 cP. Angiographic success was achieved in 18 patients (85.7%). The mean follow-up was 190 days (range, 90-538 days; median, 182 days). In the follow-up assessment, findings of magnetic resonance imaging showed that 19 patients (90.5%) had a persistent state of devascularization compared with postinterventional angiography. Amelioration or complete elimination of pain was achieved in 90.0% of the patients. One patient experienced a major adverse event; minor adverse events developed in 2 patients. CONCLUSIONS In this study, EVOH appeared to be a safe and effective embolic agent in peripheral AVMs and had a low rate of adverse events in a limited number of patients.

Abstract
OBJECTIVE In this article, we outline the important features of pancreatic cancer surgery in cases with visceral artery encasement. BACKGROUND Despite recent advances in diagnosis and treatment, pancreatic cancer continues to have a poor prognosis. Due to its limited response to chemotherapies, radiation, or targeted therapies, surgery (in combination with adjuvant chemotherapy) is the only potential way to treat pancreatic cancer in a curative manner. As only about 20% of the patients have surgically resectable disease at the time of diagnosis, the resection of encased visceral veins and arteries, along with neoadjuvant regimens, is one approach to treat otherwise palliative patients. METHODS Based on a selective literature review, we discuss the results of several studies and meta-analyses, comparing the mortality and morbidity, as well as long-term survival in patients undergoing arterial resection vs standard treatment. We conducted a selective literature review in PubMed without restrictions regarding time of publication or study design. Only articles in English language were selected. CONCLUSIONS Several studies and meta-analyses comparing resection with and without arterial resection and reconstruction showed a significantly higher post-operative mortality and morbidity and shorter long-term survival in patients who required arterial resection. In patients with tumors initially considered irresectable, the approach of neoadjuvant chemotherapy followed by resection with arterial reconstruction showed a significantly increased survival compared to palliative chemotherapy alone with acceptable postoperative morbidity. Tumor resection with arterial reconstruction following intensive preoperative chemotherapy (plus radiochemotherapy in some cases) should be considered in selected patients, as it can prolong survival and potentially lead to sustained freedom from tumor recurrence.

Abstract
Angiotensin-converting enzymes, ACE and ACE2, play not only a pivotal role in the regulation of blood pressure, but are involved in the processes of pathophysiology, including thyroid dysfunction or progression of several neoplasia such as cancers of skin, lungs, pancreas and leukemia. However, their role in the thyroid carcinogenesis remains unknown. We examined in this study the expression of ACE and ACE2 in thyroid tissues and their possible employment as biomarkers for thyroid cancer progression. Thyroid tissues, including 14 goiters (G), 12 follicular adenomas (FA), 10 follicular thyroid carcinomas (FTC), 14 papillary thyroid carcinomas (PTC) and 11 undifferentiated thyroid carcinomas (UTC), were subjected to RT-PCR and protein analyses with primers or antibodies specific for ACE and ACE2, respectively. FA revealed significantly increased ACE compared to other groups and FTC was significantly higher than UTC. ACE2 was significantly increased in PTC in comparison to G, FA and UTC, and in FTC as compared to G. The ratio ACE/ACE2 decreased, while ACE2/ACE increased with the differentiation grade of thyroid carcinoma. ACE was significantly diminished in individuals older than 50. Both ACEs were significantly diminished in M1 patients, ACE2 additionally in higher tumor masses. ACE and ACE2 are regulated within thyroid benign and malignant tissues. As the transcript ratio between both enzymes correlate proportional with the differentiation status of thyroid cancer, ACE and ACE2 may serve as new markers for thyroid carcinoma.

Abstract
The therapies available for the rare tumor entity of cervical paraganglioma (PG) are currently undergoing a paradigm shift. The treatment of choice for small carotid body tumors, malignant and active endocrine tumors is surgical resection; however, for locally advanced carotid body tumors and vagal PG, surgical therapy should be critically evaluated. Due to the immediate proximity of these hypervascularized tumors to the caudal cranial nerves, there is a risk of severe nerve damage with a significant impairment of quality of life after resection, particularly for locally advanced cervical PG, emphasizing further the importance of a restrictive surgical strategy. External radiotherapy can provide an equivalent primary therapeutic option with respect to the rate of recurrence and is accompanied by a lower morbidity. The slow rate of tumor progression and the multifocality of the familial variant of cervical PG or significant comorbidities in older, asymptomatic patients warrant a less aggressive treatment strategy for these tumors. When a wait and scan approach is implemented, a closely monitored radiological and clinical re-evaluation is of upmost importance. In a multidisciplinary approach the following critical points require consideration before a therapy is implemented,: size and location of the tumor, progression rate, genetic background, patient age and general condition, relevant comorbidities, the presence of synchronous PG and/or vasoactive catecholamine-producing tumors. Although best practice algorithms for the treatment of cervical PG have already been devised, recent innovative developments have led to more patient-tailored, individualized treatment approaches.

Abstract
Purpose Proximalization of the arterial inflow (PAI) is a promising technique which was introduced several years ago as a treatment option for patients with dialysis access-induced ischemic syndrome (DAIIS). In our institutions we have been performing PAI since 2003 and have seen positive clinical results. The aim of this prospective survey is to present the long-term results of PAI. Methods Between 2003 and 2008, forty PAI operations were performed in our institutions: 4 patients had acute pain and sensorimotor dysfunction with no lesions, 33 had small acral lesions, and 3 had extended lesions following the creation of autogenous fistulas. In 22 cases a heparinized graft was used and in 18 cases a regular PTFE-graft. Criteria for successful treeatment of the disease course were evaluated by clinical and ultrasound examinations. Results In 36 cases (90%), PAI led to clinical success which was permanent in 33 patients (82%) seen in the follow-up period of 9 to 40 months. Primary patency was 62% after 12 months and secondary patency was 75% after 18 months. Heparinized grafts led to better patency rates. In 3 out of the 4 patients with large acral lesions, graft explantation was necessary due to infection or failing success. Conclusions Based on our experience, clinical long-term results are successful in certain patients with DAIIS. The aim for the near future should be a better patency rate to minimize the need for reoperations. In cases of extended limb necrosis/gangrene results were poor. In such patients primary closure of the access must be discussed.

Abstract
Medullary thyroid carcinoma (MTC) is subdivided into sporadic (75%) and hereditary (25%) forms. Several germline mutations in the RET proto-oncogene are the source of distinct clinical phenotypes in hereditary MTC including familial MTC (FMTC) and multiple endocrine neoplasia 2A (MEN 2A) and 2B (MEN 2B). The higher the penetrance of the MEN 2 phenotype the earlier the progression of MTC which forms the basis for the currently recommended codon-related concept of prophylactic thyroidectomy. In patients with sporadic MTC, routine calcitonin (CT) measurement in nodular goiter patients has been shown to reduce the frequency of advanced tumor stages. Patients with CT levels over 100 pg/ml after pentagastrin stimulation are recommended for total thyroidectomy. In patients with unexpected sporadic MTC after histological examination, completion thyroidectomy is currently only recommended when CT levels remain elevated. The extent of lymph node dissection in patients with MTC is controversial. However, with respect to lymphonodal micrometastases, systematic compartment-oriented microdissection has been shown to reduce the frequency of lymphonodal recurrence. On the other hand, to avoid unnecessary lymph node dissection, a more individualized concept is required in the future. New chemotherapeutic agents (tyrosine kinase inhibitors), therapeutic nuclids (90Yttrium-labeled octreotide), and chemoembolization of liver metastases are currently the most promising therapeutical concepts in patients with distant metastases.

Abstract
A consensus correlating the length of the internal carotid artery stenosis (short vs. long) to the preferred Endarterectomy (Conventional Vs. Eversion) and type of anesthesia (General Vs. cervical blockade) implemented has not yet been met. In a collaboration study between two hospitals in Germany and Georgia, 215 patients were analyzed and stratified into 3 groups according to length of stenosis, surgical technique and type of anesthesia used. In this series, for eversion endarterectomy with cervical blockade, non-neurological complications commenced at 1,78%. For conventional endarterectomy performed under general anesthesia, patients with a short stenosis had no postoperative complications whatsoever, whereas the incidence rate for various neurological deficits was 2,7% for long stenosis. In case of short stenosis of the internal carotid artery, eversion endarterectomy with cervical block, seems to be an optimal choice. Whereas for long stenosis, conventional endarterectomy under general anesthesia is a more suitable option.

Abstract
Genetic testing for RET germline mutations affords rapid identification of germline carriers, offering the prospect of cure before C-cell hyperplasia (CCH) has progressed to medullary thyroid carcinoma (MTC). Although nonindex RET mutation carriers have a better prognosis than do the index patients, it remains to be ascertained whether age represents a risk factor for MTC when screening patients. The current institutional study (October 1994 through June 1999) was set up to compare asymptomatic nonindex patients who were grouped by age: < 20 years and > or = 20 years. Inclusion criteria were confirmed RET mutations in the germline, with no MTC being more advanced than pT1pN1M0. Adult patients (> or = 20 years) had MTC significantly more often (84% vs. 43%), significantly larger tumors (5 mm vs. 3 mm), and significantly higher basal calcitonin levels preoperatively (78.0 vs. 9.7 pg/ml) than their pediatric/adolescent counterparts (< 20 years). There was a close correlation between pT1 MTC and an elevated basal serum calcitonin level (r = 0.67; Spearman's rho). All three patients with lymph node metastases from MTC had elevated basal calcitonin levels. The two groups did not differ in terms of multifocality of MTC (pT1b), lymph node involvement (pN1) or bilateral lymph node metastasis (pN1b), or preoperative stimulated and postoperative basal and stimulated serum calcitonin. Prophylactic thyroidectomy should not be postponed beyond the age of 20, and it should be performed before basal serum calcitonin has turned positive. Pathologic conversion of stimulated serum calcitonin obviously marks the time in carriers of RET germline mutations when surgery should be scheduled at the latest to be prophylactic.

Abstract
BACKGROUND Head and neck paraganglioma (HNP) represent rare endocrine tumors. Therapy is decided on genetic findings, tumor characteristics (e.g. tumor size, localization and dignity), age of patient and symptoms. In terms of local control radiation therapy is as equally effective as surgery but surgical morbidity rates secondary to cranial nerve injuries remain high. PATIENTS Based on 6 patients with 11 solitary (4 patients) and multiple (2 patients) HNP (8 carotid body tumors, 1 vagal, 1 jugular and 1 jugulotympanic paraganglioma) the specific characteristics of the need for surgery as well as correct choice of treatment in cases of sporadic succinate dehydrogenase (SDH) negative and hereditary SDH positive HNP will be exemplarily demonstrated. RESULTS A total of 6 carotid body tumors (four sporadic, two hereditary) were resected in 4 patients, five as primary surgery and one as a revision procedure. In one case a preoperative embolization was performed 24 h before surgery. Malignancy could not be proven in any patient. The 30-day mortality was zero. In the patient with bilateral hereditary carotid body tumors, unilateral local recurrent disease occurred. After resection of the recurrent tumor permanent unilateral paralysis of the laryngeal nerve, glossopharyngeal nerve and hypoglossal nerve occurred. All patients were followed-up postoperatively for a mean of 64 months (range 23-78 months) with a local tumor control rate of 100%. The overall survival rate after 5 years was 100%. CONCLUSIONS Given a very strict indication with awareness of surgical risks selective surgery has a key position with low postoperative morbidity in the treatment of HNPs. We prefer surgery for small unilateral paraganglioma, malignant or functioning tumors.

Abstract
BACKGROUND Perforation of the carotid artery is a rare, life-threatening emergency. This entity is usually caused by failed puncture of jugular veins, external trauma, or infection of the vascular wall. The existence of spontaneous rupture as a cause of vessel rupture is discussed in the literature. CASE REPORT The case of a 57-year-old woman who suffered painful cervical swelling on the left side for 2 days is described. Six weeks prior to this, she had received transjugular intrahepatic shunt implantation (TIPS) via the jugular vein because of liver cirrhosis. Further signs were vocal cord dysfunction and Horners' syndrome on the left side. Computed tomography (CT) with contrast agent revealed a huge mass surrounding the common carotid artery. Differentiation between a solid tumor and carotid dissection was primarily not possible. Radiological considerations also comprised an abscess or even a paraganglioma. Only color duplex sonography revealed a pendular blood flow slightly caudal of the carotid bifurcation. In agreement with the CT findings, a calcified plaque appeared directly downstream of the presumed vessel injury. Operative revision was performed in collaboration with the vascular surgeon. Transluminal endarteriectomy and vessel reconstruction with patch plasty was performed. CONCLUSION Cervical hematoma caused by carotid injury of unknown origin is a rare differential diagnosis of sudden cervical swelling. In this case, failed venous puncture in conjunction with pre-existing arterial plaque and therewith inflammation of the vessel wall could have caused the injury and delayed carotid rupture.

Abstract
BACKGROUND Especially because of improvements in clinical neurologic monitoring, carotid endarterectomy done under local anesthesia has become the technique of choice in several centers. Temporary ipsilateral vocal nerve palsies due to local anesthetics have been described, however. Such complications are most important in situations where there is a pre-existing contralateral paralysis. We therefore examined the effect of local anesthesia on vocal cord function to better understand its possible consequences. METHODS This prospective study included 28 patients undergoing carotid endarterectomy under local anesthesia. Vocal cord function was evaluated before, during, and after surgery (postoperative day 1) using flexible laryngoscopy. Anesthesia was performed by injecting 20 to 40 mL of a mixture of long-acting (ropivacaine) and short-acting (prilocaine) anesthetic. RESULTS All patients had normal vocal cord function preoperatively. Twelve patients (43%) were found to have intraoperative ipsilateral vocal cord paralysis. It resolved in all cases < or =24 hours. There were no significant differences in operating time or volume or frequency of anesthetic administration in patients with temporary vocal cord paralysis compared with those without. CONCLUSION Local anesthesia led to temporary ipsilateral vocal cord paralysis in almost half of these patients. Because pre-existing paralysis is of a relevant frequency (up to 3%), a preoperative evaluation of vocal cord function before carotid endarterectomy under local anesthesia is recommended to avoid intraoperative bilateral paralysis. In patients with preoperative contralateral vocal cord paralysis, surgery under general anesthesia should be considered.

Abstract
BACKGROUND Dialysis shunt-associated steal syndrome (DASS) is a rare complication of hemodialysis access (HA) which preferably occurs in brachial fistulas. Treatment options are discussed controversially. Aim of this study was to evaluate flow-controlled fistula banding. MATERIALS AND METHODS Patients treated between 2002 and 2006 were included in this prospective survey. According to a classification we established, patients were typed DASS I-III (I: short history, no dermal lesions; II: long history, skin lesions; III: long history, gangrene). Surgical therapy was HA banding including controlled reduction (about 50% of initial flow) of HA blood flow (patients type I and II). Patients with type III underwent closure of the HA. RESULTS In 15 patients with relevant DASS, blood-flow-controlled banding was performed. In ten patients (all type I), banding led to restitution of the hand function while preserving the HA. In five patients (all type II), banding was not successful; in two patients, closure of the HA was performed eventually. In five patients (type III), primary closure of the HA was performed. Four patients with DASS type II but only two with DASS type I had diabetes mellitus (p = 0.006). CONCLUSIONS Banding under blood flow control resulting in an approximately 50% reduction in the initial blood flow is an adequate therapeutic option in patients with brachial HA and type I-DASS. In type II-DASS, banding does not lead to satisfying results, more complex surgical options might be more successful. Diabetes is associated with poor HA outcome in case of DASS.

Abstract
HYPOTHESIS Medullary thyroid cancer cells are capable of secreting carcinoembyronic antigen (CEA). An abnormal preoperative CEA level may have important implications for the management of this condition. DESIGN Retrospective analysis. SETTING Tertiary referral center at a university hospital. PATIENTS One hundred fifty patients with a histopathologic diagnosis of medullary thyroid cancer and preoperative CEA measurements using the same assay. Main Outcome Measure We used univariate and multivariate analyses to quantify the relationship between preoperative CEA level and tumor progression. RESULTS On multivariate analysis, abnormal preoperative CEA levels were significantly associated with the initial operation rather than reoperation, larger primary tumors, positive lymph nodes, and distant metastasis. When analyses were limited to the 54 patients with increased CEA levels before the initial operation, there was a respective significant association between successive CEA levels (4.7-10.0, 10.1-30.0, 30.1-100.0, and >100.0 ng/mL) and lymph node metastases (>10 positive nodes: 0%, 9%, 53%, and 69% [P<.001]), involvement of cervical lymph node compartments (central: 33%, 36%, 73%, and 93% [P=.002]; lateral [ipsilateral]: 20%, 27%, 67%, and 88% [P=.001]; and lateral [contralateral]: 22%, 10%, 36%, and 73% [P=.008]), and distant metastasis (0%, 27%, 13%, and 75% [P<.001]). When CEA levels exceeded 30.0 ng/mL, surgical cure was exceptional. CONCLUSIONS In medullary thyroid cancer, an abnormal CEA level heralds advanced disease. Carcinoembryonic antigen levels greater than 30.0 ng/mL indicate central and lateral (ipsilateral) lymph node metastases, whereas CEA levels greater than 100.0 ng/mL signify lateral (contralateral) lymph node metastases and distant metastasis.

Abstract
BACKGROUND No surgical standard for Riedel's thyroiditis (RT) is established. Salvage surgery follows severe cervical and compressive airway symptoms or strong suspicion of malignancy. Obscured planes and multi-infiltrative extension prevent sufficient surgery with considerate complications. No alternative definitive treatment is available. In failing conservative treatment, the role of surgery in RT remains unclear. MATERIALS AND METHODS Clinical manifestation, treatment, outcome and follow-up in a unique series of eight consecutive patients with RT are presented. RESULTS Seven female patients and one male patient with cervical tumor growth or thyroiditis underwent four total and three sub-total thyroidectomies, respectively, one patient declined remedial surgery. Complications were one bilateral laryngeal nerve palsy and one transient hypoparathyroidism. Histology confirmed RT with perithyroidal extension and excluded malignancy in all. Symptomatic relief of cervical and airway obstruction was achieved in all. Follow-up revealed two extensive mediastinal RT recurrences 1 and 6 years after surgery. CONCLUSION Favourable symptomatic outcome and alleviation of steroids in the majority render surgery for RT valuable when conservative treatment fails. However, more radical procedures show no advantages and recurrences are not prevented. The demanding technique in RT requires special surgical expertise and highly recommends intra-operative neuromonitoring.

Abstract
BACKGROUND Controversy regarding the optimal surgical treatment for secondary hyperparathyroidism (sHPT) continues. Subtotal parathyroidectomy (PTX) with a small remnant and total parathyroidectomy with autotransplantation prevail, although impaired by considerable recurrence rates. Concerns about postoperative management and long-term supplementation prevent broader acceptance of total parathyroidectomy without autotransplantation. MATERIALS AND METHODS The standardized surgical procedure with intraoperative PTH assessment (qPTH) included cervical thymectomy, histological proof of four parathyroid specimens and obligatory cryopreservation of parathyroid tissue in all 23 patients undergoing total PTX without autotransplantation. Whenever qPTH did not normalize, complete cervical exploration of ectopic sites was performed. Another 64 patients with subtotal PTX for sHPT served as comparison for the postoperative course. RESULTS There were 13 primary and 10 completion (5 persistent, 5 recurrent sHPT) total PTX with 14 concurrent thyroid resections performed. Mean preoperative PTH was 1.351 pg/ml (12-72 pg/ml) and serum calcium was 2.5 mmol/l (2.25-2.5 mmol/l). PTH showed intraoperative normalization in 15 patients and a 50% PTH reduction from preoperative values in all. Postoperative course was not significantly different from the subtotal PTX group and showed PTH within the normal range for 5 patients (4 < 35 pg/ml), 7 with PTH < 12 pg/ml, and 4 without measurable PTH. In 4 patients PTH did not normalize postoperatively. Serum calcium levels were below normal in all patients: < 2.25 mmol/l in 9, < 2.00 mmol/l in 7, and <1.8 mmol/l in 6 patients. Only 1 patient required intermittent early postoperative i.v. calcium supplementation, 6 patients received oral calcium and vitamin D supplement for low calcium levels, but no severe hypocalcemic symptoms were encountered. Mean postoperative hospital stay was 5 days. No recurrent laryngeal nerve palsies were encountered. Complications were two cervical bleedings following postoperative hemodialysis requiring evacuation. CONCLUSIONS Total PTX without autotransplantation proves to be an equally safe and successful procedure for sHPT as subtotal PTX or total PTX with autotransplantation. Measurable PTH after total PTX as demonstrated in this study, supports the idea of uncontrollable isolated cell nests that are inevitably prone to stimulated growth with time. Therefore, total PTX is superior with regard to prevention of recurrence. Adequate supplementation with calcium and vitamin D, often necessary after subtotal PTX to suppress inadequate PTH and protect from recurrence, will prevent severe hypocalcemia and with the modern aluminium-diminishing dialysis regimen, development of adynamic bone disease appears less likely than feared. If necessary, cryopreserved parathyroid tissue can be autotransplanted on demand.

Abstract
INTRODUCTION Disseminated tumor cells in the connective tissue (CT-DTCs) do not have any connection to a primary tumor or the lymph nodes. They are identified quite often in patients with medullary thyroid carcinoma (MTC), but nothing is known regarding their prognostic significance. METHODS Among 450 patients with MTC, 69 (15%) were identified as having CT-DTCs. A case-control group of patients without CT-DTCs was selected. The two groups were matched concerning TNM classification, age, heredity, and sex. Because many patients with CT-DTCs had extrathyroidal tumor extension (pT4 category), distant metastases (M1 category), or both, only 35 matched pairs could be identified. The TNM classification in both groups was as follows: pT1, n = 8; pT2, n = 15; pT3, n = 4; pT4, n = 8; pN0, n = 4; pN1, n = 31; M0, n = 30; M1, n = 5. The mean age was 46.8 +/- 17.0 years in the CT-DTC group and 44.4 +/- 15.0 years in the case-control group (NS). RESULTS In both groups, 23 patients had sporadic MTC, and 12 patients had hereditary MTC. Neither mean basal preoperative nor postoperative calcitonin levels differed significantly between the two groups. In contrast, none of the patients with CT-DTCs was biochemically cured (normal calcitonin level after pentagastrin stimulation) compared to eight patients without CT-DTCs (P < 0.005). The two groups did not differ concerning other parameters (basal calcitonin level > 3000 pg/ml, more than 10 lymph node metastases, more than two involved locoregional lymph node compartments, mediastinal lymph node metastases) that have been reported to correlate with the lack of or almost (< 10%) lack of biochemical cure. CONCLUSIONS In patients with MTC, disseminated tumor cells in the connective tissue correlate with advanced tumor stages and appear to be of prognostic significance.

Abstract
BACKGROUND Hepatic metastases from medullary thyroid carcinoma (MTC) may impair quality of life by hypercalcitonemia-associated diarrhea and pain. In this prospective study, the effect of selective arterial chemoembolization (SACE) was evaluated. METHODS Eleven patients with hepatic metastases from MTC received 1 to 9 courses of SACE using epirubicine. Symptomatic, biochemical, and morphologic responses on SACE were recorded. RESULTS Symptomatic response was observed in all symptomatic patients. However, biochemical and radiologic response occurred only in 6 patients. Liver function was not affected by SACE. One patient with unexpected concurrent pheochromocytoma metastases died after the first course. Development of side effects in the course was observed in 8 patients but were only World Health Organization grade 1. Patients' satisfaction with SACE was excellent. Long-term follow-up found 7 patients alive (1-72 months). Three patients died with tumor 6, 12, and 24 months after SACE, respectively. CONCLUSION SACE provided good symptom palliation for the majority of patients with hepatic metastases from MTC. However, transient remission or stabilization of hepatic metastases resulted in only 60%. Further studies using a randomized protocol are required.

Abstract
This work draws on recent advances during the era of codon-oriented prophylactic surgery for hereditary medullary thyroid cancer (MTC). Milestones included identification of RET (REarranged during Transfection) as the susceptibility gene, introduction of prophylactic surgery on evidence of a RET germline mutation, revelation of genotype-phenotype correlations within the MEN 2 spectrum and demonstration of age-related progression of MTC. Novel surgical techniques, notably systemic microdissection and compartment-oriented surgery, have greatly enhanced surgical cure. Uncovering molecular pathways from RET genotype to MEN 2 phenotype should provide treatment options for RET mutation carriers whose MTC currently is too advanced for cure.

Abstract
In hereditary medullary thyroid carcinoma (MTC), recommendations regarding timing and extent of surgery are mainly based on the data of patients with the codon 634 RET mutation, which is the most often affected codon. Little is known about whether these recommendations may also be applied to patients with less common RET mutations. We ascertained the data from 140 patients with FMTC/MEN2A-related RET mutation not affecting codon 634 who have been treated at three specialized centers. The several RET mutations found affected codons 611 (n = 17), 618 (n = 22), 620 (n = 17), 768 (n = 9), 790 (n = 24), 791 (n = 21), 804 (n = 23), and 891 (n = 7). For each codon, the age of the youngest patient with MTC only (41, 7, 18, 29, 13, 47, 20, and 15 years, respectively), MTC with lymph node metastases (46, 24, 21, 34, 46, 47, 50, and 76 years, respectively), and MTC with distant metastases (52, 69, 43, 68, 57, - , - , and 75 years, respectively) was determined. All patients with lymph node metastases had elevated basal calcitonin levels. Based on these data, a more individual recommendation regarding timing and extent of surgery can be given. Because neither gender nor the type of nucleotide substitution for a specific codon appeared to have a significant influence on the age of onset, this recommendation should be based on the affected codon, the age of the patient, and the calcitonin level. Recurrent laryngeal nerve palsy (n = 6) and hypoparathyroidism (n = 3) were rather rare and were found only in patients older than 30 and 43 years, respectively, giving evidence that surgery in young patients can be performed safely.

Abstract
Medullary thyroid carcinoma (MTC) is a rare disease, and most studies are either based on small numbers or multicenter studies with their inherent difficulties. Since 1995, a total of 440 patients with MTC underwent surgery in our clinic. A primary operation was performed in 188 patients (43% of 440). In 60 patients, the primary operation was performed because of a germline RET mutation ("prophylactic surgery"). Most (84%, 158/188) of the patients had pathologic calcitonin levels. Notably, MTC was found in almost 10% (3/30) of patients with normal calcitonin levels. However, all patients with lymph node metastases (LNMs) had elevated calcitonin levels. Total thyroidectomy (TTx) was performed in all patients. Lymph node dissection (LND) was performed at various extensions: one-compartment LND in 35% (66/188), three-compartment LND in 31% (58/188), and four-compartment LND in 29% (22/188). In general, lymph node dissection increased the likelihood of complications. LNM and distant metastases (DM) correlated with the extent of the primary tumor (pT category). The presence of LNM ranged from 17% (pT1 tumor) to 100% (pT4 tumor), whereas the presence of DM ranged from 0% (pT1 tumor) to 81% (pT4 tumor). Biochemical cure (normal calcitonin levels) was obtained in 72% (137/188) of patients. All 60 patients undergoing prophylactic surgery (tumor stage pT0/pT1) were biochemically cured. In contrast, only 60% (77/128) of the remaining patients were cured. The data suggest that primary surgery should be scheduled as soon as possible to treat patients at a node-negative stage. In the case of normal basal and elevated stimulated calcitonin levels, TTx and cervicocentral LND is recommended. If the basal calcitonin level is elevated, LND should include the cervicolateral compartment.

Abstract
More than 50% of patients with typical MEN-2B have a de novo M918T germline mutation of the RET protooncogene. However, even in typical MEN-2B, extrathyroidal manifestations of MEN-2B can be found to be differently expressed. We analyzed the clinical manifestation and course in 21 patients harboring a de novo RET M918T mutation. Mean age at MEN-2B diagnosis was 14.2 years (range: 1-31 years). All patients had medullary thyroid carcinoma (MTC). At the time of syndrome diagnosis, oral manifestations (bumpy lips, ganglioneuroma), ocular manifestations (corneal fibers, conjunctivitis sicca), intestinal dysfunctions, musculoskeletal manifestations, and pheochromocytoma were found in 86%, 90%, 74%, 79%, and 19% of the patients, respectively. At the time of follow-up examination, the symptoms were found at higher frequency. Severe intestinal manifestation was predominantly found in patients with prepubertal onset (< or = 12 years) of MTC (n = 4/10) compared with patients with late onset (> 12 years) of MTC (n = 0/11) (40% versus 0%; p = 0.019). Although biochemical cure was found only in four patients with early onset of MTC, the long-term prognosis for patients with early onset of MTC was poorer than for patients presenting with late onset of MTC (p = 0.005). During mean follow-up of 55.8 months (range: 3-161 months), seven patients (33%) died from MTC. In conclusion, whereas most typical MEN-2B symptoms were found to be age-related, severe intestinal manifestation was found to be predominantly expressed in patients with early onset of MTC. Furthermore, in patients with early onset of MTC who could not be biochemically cured, the long-term prognosis was found to be worse than that of non-cured patients with late onset of MTC, suggesting an additional pathological process in the younger subgroup reinforcing the very high transforming in vitro activity of the M918T RET mutation.

Abstract
BACKGROUND Subtotal bilateral adrenalectomy may preserve adrenocortical function. Little is known about the early postoperative function of the adrenal remnant. METHOD In 10 patients with bilateral adrenal tumors (pheochromocytomas, adrenocortical nodular hyperplasia, and adrenal metastases), plasma adrenocorticotropic hormone (ACTH), serum cortisol, and maximal cortisol liberation were examined with an ACTH test after subtotal bilateral adrenalectomy, which left 15% to 30% of adrenal tissue in situ. RESULTS In the early postoperative period, all patients had normal basal serum cortisol levels (mean, 415+/-208 nmol/L; normal morning range, 138-690 nmol/L) but pathologically increased plasma ACTH levels (mean, 55+/-42 pmol/mL; normal, <10.1 pmol/L). In 6 patients, a pathologic ACTH test result was observed. During follow-up (mean, 11.3+/-7.6 months), all patients were found to have a normal ACTH test result. None of the patients required steroid supplementation. However, in patients with both familial pheochromocytoma and impaired adrenocortical function during the early postoperative period, the maximal increase of serum cortisol after ACTH stimulation was significantly reduced (mean, 301+/-86.8 nmol/L) compared with control subjects (mean, 490+/-132.6 nmol/L; P=.019). CONCLUSION After subtotal bilateral adrenalectomy left 15% to 30% of adrenal tissue in situ, functional recovery could be observed in all patients. However, subclinical impairment of the adrenocortical function with questionable clinical significance has to be considered in some of the patients. Especially during the early postoperative period, careful observation of the patients without exogenous steroid administration is required.

Abstract
BACKGROUND Limited information exists about risk factors for postoperative hypoparathyroidism after bilateral thyroid surgery. METHODS Between January 1 and December 31, 1998, bilateral thyroid surgery was performed on 5846 patients for benign and malignant thyroid disease. Data were prospectively collected by questionnaires from 45 hospitals. A logistic regression model was used to determine independent risk factors. RESULTS The overall incidence of transient and permanent hypoparathyroidism was 7.3% and 1.5%, respectively. On logistic regression analysis, total thyroidectomy (odds ratio [OR], 4.7), female gender (OR, 1.9), Graves' disease (OR, 1.9), recurrent goiter (OR, 1.7), and bilateral central ligation of the inferior thyroid artery (OR, 1.7) constituted independent risk factors for transient hypoparathyroidism. When the multivariate analysis was confined to permanent hypoparathyroidism, total thyroidectomy (OR, 11.4), bilateral central (OR, 5.0) and peripheral (OR, 2.0) ligation of the inferior thyroid artery, identification and preservation of no or only a single parathyroid gland (OR, 4.1), and Graves' disease (OR, 2.4) emerged as independent risk factors. CONCLUSIONS Extent of resection and surgical technique had a greater impact on the rates of permanent postoperative hypoparathyroidism than thyroid pathologic condition. In bilateral thyroid surgery, peripheral ligation of the inferior thyroid artery at the thyroid capsule should be favored over central ligation, and at least 2 parathyroid glands should be identified and preserved. High-risk procedures, such as total thyroidectomy and Graves' disease, require special surgical training and expertise.

Abstract
BACKGROUND In patients with multiple endocrine neoplasia type 2A syndrome, prophylactic thyroidectomy is generally recommended at the age of 5 to 6 years. Whether this recommendation is justified for exon 13 mutations is unknown. METHODS We analyzed the clinical data from 40 patients harboring RET codon 790/791 mutations (exon 13) who had been treated in 4 specialized centers. RESULTS Mean age was 35.2 +/- 21.6 years (range, 5.1-69.0 years). Thirteen patients were index patients (mean age, 57.7 +/- 11.3 years), 27 patients were screening patients (mean age, 24.4 +/- 16.5 years). In the index group, pT-category was: T0, n = 2; T1, n = 6; T2, n = 2; T3, n = 1; and T4, n = 2. Lymph node metastases were found in 5 patients and distant metastases in 1 patient. Postoperatively, 69% of index patients were biochemically cured. In the screening group, pT-category was: T0, n = 19; T1, n = 7; and T2, n = 1. Lymph node metastases were found in 2 patients. Postoperatively, 93% of screening patients were biochemically cured. The youngest patient with medullary thyroid carcinoma was 13.8 years, the youngest patient with lymph node metastases was 46.4 years. CONCLUSIONS Patients with RET codon 790/791 mutations seemed to have a less aggressive clinical course compared with patients with classic multiple endocrine neoplasia type 2A syndrome. Still, index patients had a lower biochemic cure rate in comparison with screening patients. Timely total thyroidectomy including lymph node dissection is warranted.

Abstract
BACKGROUND Intraoperative neurostimulation of the recurrent laryngeal nerve may reduce nerve palsy during thyroid surgery and is well established in adults. No data regarding the value of neuromonitoring during thyroid surgery in children have been available. METHODS In a retrospective study, the authors analyzed all children who underwent surgery in our department since 1995. Neurostimulation was performed as electromyography of the vocal muscle using an electrical stimulation electrode for identification of the recurrent nerve. RESULTS The authors performed thyroid resections in 97 children (mean, 11.1 years), 75 because of thyroid carcinoma. The recurrent nerve was identified in each patient. The neuromonitoring was used in 53 patients. Postoperatively, one temporary nerve palsy was identified in this group (1.89%). In the group of 44 nonstimulated patients, 2 temporary (4.55%) and one permanent nerve dysfunctions (2.27%) occurred. In all stimulated patients, the results of intraoperative neurostimulation were identical with the postoperative function of the vocal cords. CONCLUSIONS The intraoperative neurostimulation of the recurrent laryngeal nerve is a safe and reliable procedure in children and adolescents. It may reduce nerve damage during thyroid surgery. The neuromonitoring of the recurrent nerve is of high prediction for the postoperative function of the vocal cords.

Abstract
The occurrence of papillary thyroid carcinoma in patients with RET germline mutations has been described in only eight cases since 1993. We report three women with a RET germline mutation in exon 13 and 14, affecting codon 790, 791, and 804, respectively, who underwent prophylactic thyroidectomy at the age of 29, 39, and 24 years, respectively. Histologic examination revealed C-cell hyperplasia and a small medullary thyroid carcinoma in the first patient and no pathologic changes of the C-cells in either of the other patients. However, all patients had papillary thyroid carcinoma (PTC). Concerning the frequency of PTC in patients with RET germline mutations who underwent surgery at our center (n = 104), it was found in 9.1% of all patients with RET mutation in codon 790, 791, and 804 (n = 33) but in none of the 104 patients with RET germline mutations not affecting codon 790, 791, or 804 (p = 0.0015). Our data and the data from the literature suggest a possible pathogenesis of PTC caused by exon 13 and 14 RET mutations that affect the intracellular domain of the encoded protein. Further investigation is necessary to confirm a potential pathogenetic role of exon 13 and 14 RET mutations with regard to the development of PTC.

Abstract
INTRODUCTION Our goal was to compare operative vs. conservative therapeutic strategies after injuries following ERCP. METHODS Eight patients with ERCP-induced injuries were surveyed retrospectively. Four of them were treated operatively, four conservatively. Criteria for an operative therapy were clinical and radiological findings and laboratory data. RESULTS The four patients that were treated conservatively had an uncomplicated course whereas three of four patients treated operatively had long and complicated stays. In these patients the operation was performed more than 24 hours after injury. All of them showed advanced biliary peritonitis. One patient was operated on within 24 hours. He was discharged after a short stay without complications. All injuries were located in the retroperitoneum. Five patients showed anatomical abnormality of either duodenum, papilla or common bile duct. In five cases the duodenum was involved in the injury. CONCLUSIONS The course of disease of the operated patients was longer and more complicated compared to those treated conservatively. According to our data the timing of the operation seems to be an important criterion with respect to the prognosis. Due to the small number of patients, whether conservative therapy should be preferred cannot be determined. The role of the location of injury is also not clarified.

Abstract
INTRODUCTION Calcitonin is a sensitive marker for medullary thyroid carcinoma. Normalisation of calcitonin levels following resection of medullary thyroid carcinoma has been described after a few hours; however, it may be observed more than 4 weeks after surgery. The aim of this study was to correlate the postoperative calcitonin kinetics with preoperative calcitonin levels and tumour stage. Furthermore, we wanted to test the prognostic impact of the calcitonin kinetics. Therefore, only patients with postoperative normalisation of calcitonin levels (biochemical cure) were included in this study. METHODS Fourteen biochemically cured patients were analysed, including measurement of postoperative basal and pentagastrin-stimulated calcitonin concentration. With respect to the time of postoperative basal calcitonin normalisation, patients were classified into two groups: (A) patients with normalisation of basal calcitonin levels within 24 h and (B) patients with normalisation of basal calcitonin levels later than 24 h postoperatively. RESULTS Eight patients were found to have normalisation of basal calcitonin levels within 24 h (group A). In the remaining six patients (group B), the period to normalisation of basal calcitonin levels varied from 6 days to 14 days and longer. There were no differences between the two groups with regard to tumour size, number and pattern of lymph node metastases and tumour stage. However, preoperative basal calcitonin levels were significantly different (258 ng/ml vs 955 ng/ml, P<0.01). In the group with slow-decreasing calcitonin levels, no strong correlation between the preoperative level and the postoperative time to normalisation of basal calcitonin levels could be established, which may be due to the small number of patients. After a median follow-up of 21 months, no patient developed tumour recurrence. However, an increased basal calcitonin level was observed in one patient from group B. All other patients had normal basal and peak calcitonin levels. CONCLUSION Using a highly sensitive calcitonin assay, we demonstrated that normalisation of basal calcitonin levels may be delayed in patients suffering from medullary thyroid carcinoma. The lack of correlation of preoperative levels and the time to normalisation of the basal calcitonin levels, as well as the positive pentagastrin test in some of the patients, argues that this phenomenon is not simply due to prolonged biochemical calcitonin elimination. Nevertheless, a prognostic influence could not be shown in this study due to the short follow up-period. Further investigations and a longer follow-up are necessary to determine the nature and the prognostic impact of delayed normalisation of calcitonin levels.

Abstract
A quality control study was undertaken on 7,265 patients with benign goitre and 352 patients with malignant goitre who were surgically treated between 1.1.98 and 31.12.98. 3 hospital groups were defined according to surgical workload: Group 1: < 50 operations/yr; Group 2: 50-150 operations/yr; Group 3: > 150 operations/yr. The temporary rate of recurrent laryngeal nerve (RLN) palsies for benign goitre was 3.9% and the permanent 1.1%. For malignant goitre the rates were 12.8% and 6.8% respectively. The rate of temporary (p < 0.040) and permanent (0.003) palsies after surgery for benign goitre was lower in group 3 compared to group 1 and 2. There were too few cases for statistical analysis of the malignant goitres. After benign goitre surgery a transient hypocalcaemia rate of 6.3% and a permanent of 1.1% were observed. For malignant goitre the incidence was 23.8% and 7.1%, respectively. A significantly increased rate of permanent hypocalcaemia (p < 0.003) was demonstrated in group 3 after surgery for multinodular goitre. Centres in group 3 made more extended (smaller thyroid remnants) resections (p < 0.01) with the equivalent rate of general complications. The average inpatient stay for malignant goitres was 13.1 days and for benign goitres 8.7 days. On average, patients with bilateral resections for benign goitre stayed 0.4 days longer in hospital than those with unilateral procedures. Prophylactic antibiotics were administered to 2.1% of patients and 94.6% received thrombosis prophylaxis.

Abstract
Based on two patients with vascular complications in thoracic outlet-syndrome, the anatomic and pathophysiologic principles prior to surgery are discussed. Causative therapy including rib resection and elimination of the embolic source in the subclavian artery is often supplemented by peripheral revascularization with bypass, lysis and/or sympathectomy. The transaxillary approach seems to be optimal, combining minimally invasive principles with a long exposure of the subclavian artery from segment 3 to the proximal axillary artery.

Abstract
Risk factors for postoperative complications of benign goiter surgery have not been investigated systematically. To this end, a prospective multicenter study (January 1 through December 31, 1998) was conducted involving 7266 patients with surgery for benign goiter from 45 East German hospitals. High-volume providers (>150 operations per year) performed 69% (5042/7266), intermediate-volume providers 27% (50-150), and low-volume providers 4% (258/7266) of operations. Among the hospital groups, the pattern of thyroid disease did not vary significantly, but there was a trend that small-volume providers tended to perform more operations for uninodular goiter and high-volume providers treated more patients with Graves' disease and recurrent goiter. Extent of resection (p < 0.0001) and remnant size (multinodular goiter and recurrent goiter, p < 0.001), differed significantly, with total thyroidectomy being performed more often in hospitals with more than 150 operations compared to hospitals with an operative volume of less than 150 procedures per year. Despite the larger extent of resection and smaller remnant size, rates of recurrent laryngeal nerve (RLN) palsy or hypoparathyroidism were not increased. When the logistic regression analyses were fitted to evaluate the impact of risk factors on transient and permanent RLN palsy and hypoparathyroidism, larger extent of resection [relative risk (RR) 1.5-2.1] and recurrent goiter (RR 1.8-3.4) consistently evolved as independent risk factors. With hypoparathyroidism, additional significant factors included patient gender (RR 2.1-2.4), hospital operative volume (RR 0.8-1.5), and Graves' disease (RR 2.8). Unlike parathyroid gland identification during hypoparathyroidism, RLN identification (RR 1.6) significantly (p = 0.01) reduced permanent RLN palsy rates. The multivariate analyses clearly confirmed the pivotal role of routine RLN identification, independent of the extent of the thyroid resection. These findings might help hospitals with lower operative volumes to identify patients at increased risk whom they might consider for specialist care.

Abstract
BACKGROUND The aim of this study was to identify better prognostic parameters for normalization of serum calcitonin in medullary thyroid carcinoma (MTC) patients. METHODS In 73 patients who had undergone systematic lymph node dissection for MTC between September 1995 and November 1998, preoperative (n = 29) and postoperative (n = 65) basal and stimulated serum calcitonin were correlated with the pTNM classification and the number of positive regional lymph nodes and compartments. RESULTS In contrast to pT and M, there was a significant correlation between postoperative calcitonin and the pN category. With rising numbers of positive lymph nodes (0, 1-9, 10-19, and > or = 20), postoperative basal and stimulated calcitonin increased exponentially, and gross distant metastases (M1) occurred more frequently (0%, 4%, 13%, and 50%; P = 0.013). Conversely, serum calcitonin was less often normalized (65%, 31%, 0%, and 0%; P = 0. 003). There was a close correlation between the number of positive lymph nodes and the number of affected compartments (P < 0.001; r = 0.93). Irrespective of location, involvement of 10 or more lymph nodes and more than 2 compartments precluded normalization of serum calcitonin. CONCLUSIONS Quantitative lymph node analysis of MTC improves prediction of calcitonin normalization. When more than two compartments are involved, normalization of serum calcitonin cannot be attained. Surgery should then be less extensive and more directed at preventing local complications.

Abstract
BACKGROUND In medullary thyroid carcinoma (MTC), the effectiveness of repeat mediastinal lymph-node dissection for palliation of specific symptoms caused by discrete mediastinal lesions is unclear in non-bulky tumor disease. METHODS Between November 1994 and August 1998, five symptomatic MTC patients with radiologic evidence of mediastinal tumor and elevated calcitonin levels were subjected to repeat mediastinal lymph-node dissection. RESULTS At reoperation, an average of 7 of 25 (28%) removed cervical and 5 of 9 (56%) dissected mediastinal lymph-nodes were positive on histopathology. A substantial fraction of these were excised from anatomical regions inaccessible through a purely cervical or partial sternotomy approach. Clinical symptoms were effectively palliated in all five patients. Basal serum calcitonin levels fell only moderately, suggesting distant micrometastases. Mortality was nil. Morbidity encompassed two cases of hypoparathyroidism and a lymphatic fistula that closed spontaneously on total parenteral nutrition. One patient later required cervical reoperation deferred at secondary surgery. All five patients have since remained free of cervical and mediastinal tumor at a mean follow-up of 15 months. CONCLUSIONS In mediastinal lymph-node metastases, repeat lymph-node dissection is warranted for palliation of discrete anatomic lesions inaccessible through a cervical approach.

Abstract
Normalization of calcitonin levels after surgery has been regarded as the most powerful prognostic factor for medullary thyroid carcinoma (MTC). Although the prognosis of patients with persistent hypercalcitoninemia may be acceptable, the biochemical cure rate can be improved by new microdissection techniques. This raises certain questions: Can extension of locoregional lymphadenectomy (LA) further improve biochemical cure and survival after primary or reoperative MTC surgery? Which factors concerning TNM categories are associated with the possibility of postoperative normalization of calcitonin levels? This study included 64 patients with sporadic MTC operated on from 1986 to 1997. Altogether 27 patients underwent primary surgery, and 37 patients were reoperated, performing a microdissection of all four locoregional compartments (four-compartment lymphadenectomy, or 4CLA). For primary MTC the biochemical cure rate was 100% in node-negative patients and 33% in node-positive patients; the latter could be improved to 45% after 4CLA. In contrast to reoperative MTC, the rate of lymph node metastases (LNMs) with primary MTC correlated with the pT category (pT1 33%, pT2 53%, pT3 100%, pT4 100%) but not with age or sex. Again in contrast to reoperative MTC, mediastinal LNMs in primary MTC were present only in patients with a pT4 tumor. At reoperation, 4CLA was able to cure 22% of node-positive patients, 28% without proved distant metastases. No patient with extrathyroidal tumor involvement or distant metastases was biochemically cured after either primary or reoperative surgery. For all node-positive MTC patients, in addition to cervicocentral LA at least a bilateral cervicolateral LA is recommended. Transsternal mediastinal lymph node dissection is indicated in patients with LNMs in the cervicomediastinal transition, facilitating biochemical cure in up to 45% after the first operation and 22% after reoperative surgery of sporadic MTC.
