Effectiveness of Intraoperative Parathyroid Monitoring (ioPTH) in predicting a multiglandular or malignant parathyroid disease
Aim The main goal of our study was to confirm the usefulness of intra-operative parathyroid hormone (PTH) monitoring (ioPTH) when using minimally invasive techniques for treatment of sporadic Primary hyperparathyroidism (pHTP). Furthermore, we aimed to evaluate if ioPTH monitoring may help to predict the etiology of primary hyperparathyroidism, especially in malignant or multiglandular parathyroid disease. Methods A retrospective review of 125 consecutive patients with pHPT who underwent parathyroidectomy between 2001 and 2016\ua0at the Department of General Surgery was performed. For each patient, the specific preoperative work-up consisted of: high-resolution US of the neck by a skilled sonographer, sestamibi parathyroid scan, laryngoscopy, and serum measurement of PTH, serum calcium levels, and serum 25(OH)D levels. Results The study included 125 consecutive patients who underwent surgery for pHPT. At the histological examination, we registered 113 patients with simple adenomatous pathology (90,4%), 5 atypical adenomas (4%), 3 cases of parathyroid carcinoma (2,4%), and 4 histological exams of different nature (3,2%). Overall, 6 cases (4,8%) of multiglandular disease were found. We reported 10 cases (8%) of recurrent/persistent hyperparathyroidism: 1/10 in a patient affected by atypical adenoma, 9/10 in patients with benign pathology. Regarding these 10 cases, in three (30%) patients, ioPTH wasn't dosed (only frozen section (FS) exam was taken), in 5 cases (50%) ioPTH dropped more than 50% compared to basal value (false negative results), and in 2 (20%) cases, ioPTH did not drop >50% from the first samples taken, the extemporary exam had confirmed the presence of adenoma and the probable second hyperfunctioning adenoma was not found. Conclusions IoPTH determinations ensure operative success of surgical resection in almost all hyperfunctioning tissue; in particular it is very important during minimally invasive parathyroidectomy, as it allows avoiding bilateral neck exploration. The use of ioPTH monitoring offer increased sensitivity in detecting multiglandular disease and can minimize the need and risk associated with recurrent operations, and may facilitate cost-effective minimally invasive surgery. Moreover, intraoperative PTH monitoring could be a reliable marker to predict a malignant disease during parathyroidectomy, showing higher ioPTH baseline value and superior drop compared to benign disease
Rationality in prophylactic central neck dissection in clinically node-negative (cN0) papillary thyroid carcinoma: Is there anything more to say? A decade experience in a single-center
10noAim: Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy. Despite its extremely favorable prognosis, cervical lymph node metastases are a common feature of PTC and a known independent risk factor for local recurrence. However, the role of prophylactic central neck dissection (PCND) remains a matter of debate in patients with clinically node-negative (cN0) PTC. To better clarify the current role of PCND in the surgical treatment of PTC, evaluating advantages and disadvantages of PCND and outcome of cN0 PTC patients who have been treated with either total thyroidectomy alone or in combination with PCND. A review of recent literature data is performed.
Methods: Between January 2000 and December 2015, 186 consecutive patients with cN0 PTC were identified to be included in the present study. 74 of these underwent total thyroidectomy associated with PCND, while 112 patients underwent total thyroidectomy alone. The epidemiological and clinicalpathological data of all patients included were collected at diagnosis and during follow-up.
Results: Overall complication rate was significantly higher in the group of patients undergoing PCND (39.2% vs. 17.8%, p ¼ 0.0006). To be specific, they presented a considerably increased risk of temporary recurrent laryngeal nerve injury (p ¼ 0.009) and of permanent hypothyroidism (p ¼ 0.016). Overall survival and recurrence rates did not differ between those undergoing PCND and those undergoing total thyroidectomy alone (p ¼ 1.000 and p ¼ 0.715, respectively).
Conclusions: The results of the present study do not support the routine use of PCND in the treatment of cN0 PTC patients.partially_openopenDobrinja, C; Troian, M.; Cipolat Mis, T.; Rebez, G.; Bernardi, S.; Fabris, B.; Piscopello, L.; Makovac, P.; Di Gregorio, F.; de Manzini, N.Dobrinja, Chiara; Troian, Marina; CIPOLAT MIS, Tommaso; Rebez, Giacomo; Bernardi, Stella; Fabris, Bruno; Piscopello, L.; Makovac, Petra; Di Gregorio, F.; de Manzini, Nicolo
Effect of the COVID-19 pandemic on surgery for indeterminate thyroid nodules (THYCOVID): a retrospective, international, multicentre, cross-sectional study
Background Since its outbreak in early 2020, the COVID-19 pandemic has diverted resources from non-urgent and elective procedures, leading to diagnosis and treatment delays, with an increased number of neoplasms at advanced stages worldwide. The aims of this study were to quantify the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic; and to evaluate whether delays in surgery led to an increased occurrence of aggressive tumours.Methods In this retrospective, international, cross-sectional study, centres were invited to participate in June 22, 2022; each centre joining the study was asked to provide data from medical records on all surgical thyroidectomies consecutively performed from Jan 1, 2019, to Dec 31, 2021. Patients with indeterminate thyroid nodules were divided into three groups according to when they underwent surgery: from Jan 1, 2019, to Feb 29, 2020 (global prepandemic phase), from March 1, 2020, to May 31, 2021 (pandemic escalation phase), and from June 1 to Dec 31, 2021 (pandemic decrease phase). The main outcomes were, for each phase, the number of surgeries for indeterminate thyroid nodules, and in patients with a postoperative diagnosis of thyroid cancers, the occurrence of tumours larger than 10 mm, extrathyroidal extension, lymph node metastases, vascular invasion, distant metastases, and tumours at high risk of structural disease recurrence. Univariate analysis was used to compare the probability of aggressive thyroid features between the first and third study phases. The study was registered on ClinicalTrials.gov, NCT05178186.Findings Data from 157 centres (n=49 countries) on 87 467 patients who underwent surgery for benign and malignant thyroid disease were collected, of whom 22 974 patients (18 052 [78 center dot 6%] female patients and 4922 [21 center dot 4%] male patients) received surgery for indeterminate thyroid nodules. We observed a significant reduction in surgery for indeterminate thyroid nodules during the pandemic escalation phase (median monthly surgeries per centre, 1 center dot 4 [IQR 0 center dot 6-3 center dot 4]) compared with the prepandemic phase (2 center dot 0 [0 center dot 9-3 center dot 7]; p<0 center dot 0001) and pandemic decrease phase (2 center dot 3 [1 center dot 0-5 center dot 0]; p<0 center dot 0001). Compared with the prepandemic phase, in the pandemic decrease phase we observed an increased occurrence of thyroid tumours larger than 10 mm (2554 [69 center dot 0%] of 3704 vs 1515 [71 center dot 5%] of 2119; OR 1 center dot 1 [95% CI 1 center dot 0-1 center dot 3]; p=0 center dot 042), lymph node metastases (343 [9 center dot 3%] vs 264 [12 center dot 5%]; OR 1 center dot 4 [1 center dot 2-1 center dot 7]; p=0 center dot 0001), and tumours at high risk of structural disease recurrence (203 [5 center dot 7%] of 3584 vs 155 [7 center dot 7%] of 2006; OR 1 center dot 4 [1 center dot 1-1 center dot 7]; p=0 center dot 0039).Interpretation Our study suggests that the reduction in surgical activity for indeterminate thyroid nodules during the COVID-19 pandemic period could have led to an increased occurrence of aggressive thyroid tumours. However, other compelling hypotheses, including increased selection of patients with aggressive malignancies during this period, should be considered. We suggest that surgery for indeterminate thyroid nodules should no longer be postponed even in future instances of pandemic escalation.Funding None.Copyright (c) 2023 Published by Elsevier Ltd.

Minimally invasive video-assisted thyroidectomy compared with conventional thyroidectomy in a general surgery department.
Background We retrospectively evaluated a series of
patients who underwent minimally invasive video-assisted
thyroidectomy (MIVAT) to define its advantages or
disadvantages.
Methods Between May 2005 and March 2008, 68
patients underwent MIVAT. Sixty-nine patients who
underwent conventional thyroidectomy (CT) during the
period before the introduction of the MIVAT technique in
our department—chosen with the same inclusion criteria
used for MIVAT—served as matched controls. The eligibility
criteria for both groups was thyroid nodules
B35 mm, thyroid volume \25 ml, no thyroiditis, and no
previous surgery.
Results Forty-five MIVAT and 43 CT patients underwent
hemithyroidectomy. Twenty-three MIVAT and 26 CT
patients underwent total thyroidectomy. No differences
were found in terms of complications, operative time, and
radicality of the procedure. Patients who underwent MIVAT
experienced significantly less pain, better cosmetic
results, and shorter hospital stay than patients who underwent
conventional surgery
Conclusion The MIVAT technique, in selected patients,
seems to be a valid option for thyroidectomy and even
preferable to conventional surgery because of its significant
advantages, especially in terms of cosmetic results, postoperative
pain, and postoperative recovery
Primary Hyperparathyroidism in Older People: Surgical Treatment with Minimally Invasive Approaches and Outcome
Introduction. Elderly patients with primary hyperparathyroidism (pHPT) are often not referred to surgery because of their associated comorbidities that may increase surgical risk. The aim of the study was to review indications and results of minimally invasive approach parathyroidectomy in elderly patients to evaluate its impact on outcome. Materials and Methods. All patients of 70 years of age or older undergoing minimally approach parathyroidectomy at our Department from May 2005 to May 2011 were reviewed. Data collected included patients demographic information, biochemical pathology, time elapsed from pHPT diagnosis to surgical intervention, operative findings, complications, and results of postoperative biochemical studies. Results and Discussion. 37 patients were analysed. The average length of stay was 2.8 days. 11 patients were discharged within 24 hours after their operation. Morbidity included 6 transient symptomatic postoperative hypocalcemias while one patient developed a transient laryngeal nerve palsy. Time elapsed from pHPT diagnosis to first surgical visit evidences that the elderly patients were referred after their disease had progressed. Conclusions. Our data show that minimally invasive approach to parathyroid surgery seems to be safe and curative also in elderly patients with few associated risks because of combination of modern preoperative imaging, advances in surgical technique, and advances in anesthesia care
Case report: pancreatic injury following blunt abdominal trauma during a soccer game.
This article reports a case of unusual pancreatic trauma, underestimated initially and treated surgically at a later stage. A 26-year-old man presented with an abdominal trauma sustained during a soccer game. The patient arrived 24 hours after the trauma with abdominal pain associated to vomiting and intestinal occlusion. Laboratory tests revealed elevated serum amylase levels. An abdominal computed tomography (CT) scan showed a pancreatic parenchymal dishomogeneity at the passage between body and tail, highly suspicious for pancreatic full thickness laceration. Magnetic resonance pancreatography (MRP) demonstrated possibile duct involvement. The patient was urgently submitted to distal pancreatectomy with splenectomy. This case demonstrates a rare mechanism of injury and the potential importance of serial CT scans in the diagnosis, grading, and managemente of isolated pancreatic injury
Idiopathic mesenteric venous thrombosis: report of a case.
Introduction.—Idiopathic mesenteric venous thrombosis is a rare entity. An early diagnosis and
thrombolytic and anticoagulant therapy are very important.
Patient and methods.—We report a case of a patient, without any specific known risk factor,
with small intestinal ischemia secondary to superior mesenteric vein thrombosis (SMVT).
Results.—In our case, only a computed tomography (CT) abdominal scan permitted the diagnosis
of SMVT. The patient was successfully treated by resection of the infarcted bowel with primary
anastomosis and immediate postoperative anticoagulation.
Conclusions.—Diagnosis of intestinal ischemia from mesenteric venous thrombosis (MVT) is
often delayed because the symptoms are nonspecific. Moreover, when there is not any known
predisposing factor, the diagnosis may become even more difficult with significant morbidity
and mortality. CT abdominal scan done early in case of nonspecific abdominal pain, since the
patients had a previous history of venous thrombosis, may not require a surgical treatment of
