INTRODUCTION Prognosis of thyroid cancer is strictly related to loco-regional metastases. Cervical lymphadenectomy has a specific oncologic role but may lead to significant increase of morbidity. Aim of the study is the analysis of surgical morbidity in cervical lymphadenectomy for thyroid cancer. METHODS We retrospectively analyzed 1.765 thyroid cancers operated over a period of 25 years at S. Maria University Hospital, Terni, University of Perugia, Italy. Type of lymphadenectomy, histology and complications were analysed. RESULTS A prevalence of differentiated and medullary cancers was observed (respectively 88% and 7.2%). Central lymphadenectomy was carried out in 425 patients, lateral modified and radical lymphadenectomy respectively in 651 and 17 cases. Following central neck dissection we observed: bilateral and unilateral temporary recurrent nerves palsy respectively of 0.7% and 3.5%, unilateral permanent palsy in 1.6% of cases, temporary and permanent hypoparathyroidism respectively in 17.6% and 4.4%. After lateral neck dissection we observed: intra and post-operative haemorrhage respectively in 2% and 0.29%, respiratory distress in 0.29%, lesions of facial nerve in 0.44%, of vagus in 0.14%, of phrenic nerve in 0.14%, of hypoglossal nerve in 0.29%, of the accessory nerve, transient in 1.34% and permanent in 0.29%, permanent lesion of cervical plexus in 0.29%, salivary fistula in 0.14% and chylous fistula in 1.04% of patients. Students t test was used to compare groups when appliable. CONCLUSION Central and lateral cervical lymph node dissection are associated to severe morbidity. Correct indication, surgical expertise, high volume of patients and early multidisciplinary management of complications is the key of an acceptable balance between oncologic benefits and surgical morbidity.

AbstractColonic diverticular disease is the most common cause of lower gastrointestinal bleeding. In the past, this condition was usually managed with urgent colectomy. Recently, the development of endoscopy and interventional radiology has led to a change in the management of colonic diverticular bleeding.The aim of this systematic review is to define the best treatment for colonic diverticular bleeding.A systematic bibliographic research was performed on the online databases for studies (randomized controlled trials [RCTs], observational trials, case series, and case reports) published between 2005 and 2014, concerning patients admitted with a diagnosis of diverticular bleeding according to the PRISMA methodology.The outcomes of interest were: diagnosis of diverticulosis as source of bleeding; incidence of self-limiting diverticular bleeding; management of non self-limiting bleeding (endoscopy, angiography, surgery); and recurrent diverticular bleeding.Fourteen studies were retrieved for analysis. No RCTs were found. Eleven non-randomized clinical controlled trials (NRCCTs) were included in this systematic review. In all studies, the definitive diagnosis of diverticular bleeding was always made by urgent colonoscopy. The colonic diverticular bleeding stopped spontaneously in over 80% of the patients, but a re-bleeding was not rare. Recently, interventional endoscopy and angiography became the first-line approach, thus relegating emergency colectomy to patients presenting with hemodynamic instability or as a second-line treatment after failure or complications of hemostasis with less invasive treatments.Colonoscopy is effective to diagnose diverticular bleeding. Nowadays, interventional endoscopy and angiographic treatment have gained a leading role and colectomy should only be entertained in case of failure of the former.

INTRODUCTION Anaplastic thyroid carcinoma (ATC) is characterized by local invasiveness, risk of recurrence and very poor prognosis. METHODS We retrospectively analysed the multimodality treatment of ATC in 79 patients considering the impact of surgery on survival. RESULTS Patients were divided in two age groups A and B (cut-off 75 years) and in two size subgroups (cut-off 5 cm). Surgery was performed in 78.5% patients of group A and 32.4% of B (p < 0.05). Radiation respectively in 73.8% and 43.2% (p < 0.05). Tracheostomy and endoprosthesis were used in 45.2% and 16.6% in group A and in 43.2% and 35.1% in group B. The use of tracheostomy was significantly higher (p < 0.05) in larger tumours. In group B comparing operated and not operated patients significant difference in survival was observed for larger tumours (p = 0.043). In Kaplan Meir analysis significant difference in survival was observed comparing surgical and no surgical patients of all four subgroups. Surgery plus radiotherapy offered a significant better outcome in smaller tumours (p = 0.017). Considering the effect of the single treatment, compared to no treatment at all, survival is significantly improved by surgery for smaller and larger tumours respectively with 4.42 (p = 0.001) and with 3.5 months (p = 0.0001) and by radiotherapy respectively with 3.44 and with 3.28 months (p = 0.047 and p = 0.0001). CONCLUSION In elderly patients with ATC, although poor prognosis, surgery is still fundamental in the multimodality treatment with significant advantage in selected patients. Nevertheless most of elderly patients with large tumours are suitable only for palliative management.

BACKGROUND Sentinel lymph node (SLN) biopsy plays a major role in the surgical management of primary breast cancer. The aim of this study was to assess the diagnostic accuracy of the assessment of axillary frozen sections of SLNs for micrometastasis diagnosis. PATIENTS AND METHODS This study focused on 250 SLNs from 137 patients. Each lymph node was fully analyzed by frozen section. After fixation, serial sections were cut and stained by hematoxylin and eosin (HE) and for pan-cytokeratins by immunohistochemistry (IHC). RESULTS Tumor cells were detected in 57 SLNs, 37 on frozen sections and 20 on controls. Of these 57 positive SLNs, 38 contained metastases, 9 contained micrometastases and 10 contained isolated tumor cells. The specificity and positive predictive value of SLN frozen sections for micrometastasis was 100%. The sensitivity was 83.3% for metastasis, 40% for micrometastasis; the false-negative rate was 16.7% for metastasis and 60% for micrometastasis. CONCLUSION Analysis of frozen section of SLNs is an accurate method for metastasis detection, allowing concurrent axillary dissection when positive. The protocol for SLN analyses described herein shows good sensitivity for micrometastasis detection.

Aim. A residual mediastinal thyroid (“forgotten goiter”) is a well-known, though uncommon, complication of total thyroidectomy. Materials of study. The authors analyze their experience with three cases of goiter forgotten, observed in a series of 2946 thyroid resections in the period 2005–2010. In the study, a preoperative CT of the chest with three-dimensional reconstruction was always performed to examine the topographical relationships of the lesion. Excision was performed through cervicotomy, cervicosternotomic approach and cervicosternotomy, and posterolateral right thoracotomy. Results. There were no complications. Histological examination was suggestive of malignancy in one case (follicular carcinoma with pulmonary metastases). Discussion. The indication for surgery in cases of forgotten goiter is intrinsic to the diagnosis. Preoperative evaluation with accurate topographic imaging is required in all cases in order to understand the nature and location of mediastinal pathological tissue and to identify the most suitable access route. The cervicotomy is the ideal access for low surgical trauma and is easily extendable into a partial or complete sternotomy. A thoracotomy, on the other hand, which is usually reserved for the right side, must be planned preoperatively.

IntroductionGastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms (85%) of the gastrointestinal (GI) tract; duodenal GISTs constitute 3–5% of all GISTs and represent 10–30% of all malignant tumours of the duodenum. Rarely, patients present severe bowel obstruction, perforation or severe bleeding. The radical resection with complete removal of the tumour remains the main therapeutic approach. We performed a local resection in patients with suspected GIST admitted for emergency treatment for GI bleeding.CasesWe present three cases of patients admitted for GI bleeding. The cause could be a GIST bleeding. In all cases, local resection was performed without a pancreaticoduodenectomy. Histological examination on surgical preparations showed that in two cases it was a GIST and in one case, it was a leiomyoma.DiscussionSurgery remains the treatment of choice in the case of a GIST primitive without evidence of metastases, even for patients who are hospitalized for a bleeding emergency. Wide resections are not needed; it is important to remove completely the disease. In the case of duodenal GIST, it is important to get negative margins near the head of the pancreas, and this could take a PD. According to our experience and to the literature review, we believe that if the duodenal papilla or the periampullary region is not interested, you must perform a local resection. This is also because non-malignant tumours may present as GISTs and in these cases it is not recommended to run a PD.ConclusionThe treatment of choice for duodenal GISTs is complete surgical resection with negative resection margins. When the papilla or the periampullary region is involved we choose to perform pancreaticoduodenectomy; otherwise it is better to perform a local resection. In fact, local resection has lower morbidity and mortality, with a comparable outcome.

BackgroundSecondary hyperparathyroidism in elderly fragile patients presents clinical difficulties due to severity of symptoms and related comorbidity. The optimal surgical approach for this group of patients is still debated.AimThe aim of the study was to define the optimal technique of parathyroidectomy in elderly patients with secondary hyperparathyroidism.MethodsRetrospective analysis in a series of 253 patients including 35 elderly individuals at a single institution was carried out. Postoperative parathyroid hormone decrease, surgical complications and symptoms control were analyzed for all patients in relation to the types of parathyroidectomy performed.Results In elderly patients, total parathyroidectomy was the most used approach. Subtotal parathyroidectomy was mostly reserved for younger patients suitable for kidney transplantation. No elderly patients treated with total parathyroidectomy were autotransplanted. No significant difference in surgical complications was observed between younger and elderly patients and considering the different procedures. Adequate symptom control after surgery was achieved in almost 90% of patients. A limited rate of recurrence requiring repeat surgery was observed only after subtotal parathyroidectomy.DiscussionConsidering the features of all types of parathyroidectomy, very low recurrence rate, contained postoperative hypocalcemia and limited complications following total parathyroidectomy, might represent specific advantages for elderly patients.ConclusionsTotal parathyroidectomy without parathyroid transplantation is safe for elderly patients with secondary hyperparathyroidism and a good alternative to the well-established total parathyroidectomy with autografting.

BackgroundDiverticular disease of the colon also affects older people. Generally, older patients with diverticulitis may be regarded as too risky to undergo surgery. This retroprospective multicentric observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage (LPL) in elderly patients with perforated sigmoid diverticulitis.Patients and methodWe hospitalized in urgency 100 patients, aged over 75, for sigmoid diverticulitis. Sixty-nine patients were treated with conservative medical therapy, while 31 were treated surgically, in which the surgery was performed in urgency in 18 cases, while in election in 13 cases. Laparoscopic peritoneal lavage was made in urgency in five cases.ResultsThe mean age of the sample was 81.72. Thirty-one patients underwent surgery, and five patients were treated in urgency with laparoscopic peritoneal lavage. Perioperative mortality was zero. None of the patients who underwent laparoscopic peritoneal lavage showed recurrent disease.ConclusionDiagnostic laparoscopy can be useful in elderly patient, since these patients may benefit from a more conservative surgical strategy. The selection of patients to be subjected to laparoscopic lavage must be very rigorous.

AIM Surgery for mediastinal goiters (MG) is indicated for compression symptoms and risk of malignancy. Total thyroidectomy by cervicotomy is universally considered the standard surgical approach to MG. In selected cases sternotomy or a thoracotomy are used. Options of the operative technique and practical surgical problems are analysed. METHODS A retrospective analysis of twenty-eight-years on 1767 cases of MG in a referral centre for endocrine surgery was carried out. All patients underwent standard preoperative study and CT based surgical planning. Surgery was performed by an experienced surgical team with standard technique via cervical approach or in selected case via sternotomy or thoracotomy. Clinical records were examined. RESULTS Total thyroidectomy was performed in all cases. A cervical approach was used in almost 99% of patients. Significant shorter surgical time was observed for surgery via the cervical approach vs sternotomy and thoracotomy. Benign struma was observed in 1503 patients and a carcinoma in 264. We observed postoperative bleeding in 0.5% of cases, permanent monolateral recurrent laryngeal nerve palsy occurred in 1.3%, bilateral palsy in 0.6%, transient and permanent hypoparathyroidism in 14% and 4.1% respectively. CONCLUSION MG may be approached by a cervicotomic access only with a clear knowledge of potential risk and complications of the surgical manoeuvres. Sternotomy or of a thoracotomy are indicated only in selected cases but their inapplicability may be really dangerous in those MG not otherwise resectable. MG should be referred only to specialized centre.
