BACKGROUND
At present, there is no consensus on optimal neck wound closure methods after thyroid and parathyroid surgery. The aim of this study was to perform a systematic review and network meta-analysis of RCTs evaluating the optimal neck closure method after thyroid and parathyroid surgery.
METHODS
A frequentist random-effects network meta-analysis was performed for RCTs comparing at least two closure methods according to PRISMA-network meta-analysis guidelines. Analysis was performed using R packages and Shiny.
RESULTS
Eighteen RCTs evaluating six closure methods (that is adhesive (28.5 per cent, 404 patients), absorbable subcuticular suture (18.1 per cent, 257 patients), non-absorbable subcuticular suture (16.8 per cent, 238 patients), staples (26.3 per cent, 372 patients), steristrips (8.1 per cent, 115 patients), and conventional suture (2.1 per cent, 30 patients)) in 1416 patients were included. At network meta-analysis, there was no difference in complication, infection, dehiscence, or haematoma rates irrespective of closure method used. Staples reduced closure duration versus absorbable subcuticular suture (mean difference (MD) 8.50, 95 per cent c.i. 6.90 to 10.10) and non-absorbable subcuticular suture (MD 0.30, 95 per cent c.i. 0.23 to 0.37), whereas adhesives (MD -1.05, 95 per cent c.i. -1.31 to -0.79) reduced closure time relative to staples. Cosmesis was improved after non-absorbable subcuticular suture (odds ratio (OR) 3.41, 95 per cent c.i. 1.66 to 7.00) relative to staples. Staples reduced patient satisfaction (OR 0.04, 95 per cent c.i. 0.00 to 0.33) and ability to shower (OR 0.04, 95 per cent c.i. 0.00 to 0.33) relative to adhesives.
CONCLUSION
Despite staples decreasing closure times, this advantage is offset by reduced patient satisfaction, ability to shower, and cosmesis compared with patients with wounds closed using adhesives, absorbable subcuticular suture, and non-absorbable subcuticular suture. Therefore, these closure methods are favourable for closing neck wounds due to more acceptable patient-reported outcomes, without compromising the safety of the procedure.

Meta-Analysis
INTRODUCTION
Primary hyperparathyroidism (pHPT) is a common endocrine disorder caused by an autonomous overproduction of parathyroid hormone (PTH) by a parathyroid gland. Over the last decade, F-choline (FCH) PET has emerged as a highly performant imaging technique for guiding parathyroidectomy. As cure is the goal of surgery, the main aims of this study were to summarize patient-based sensitivity, positive predictive value (PPV), and cure rate of FCH PET guided surgery in the surgical management of pHPT.
EVIDENCE ACQUISITION
We conducted a systematic review and metaanalysis according to the PRISMA Guidelines. A literature search was performed in the PubMed, Web of Science and Cochrane databases, last updated November 2022. Original articles on choline PET in patients with pHPT mentioning patient-based sensitivity, PPV and cure rate were retained. Quality of included studies was assessed using the QUADAS-2 Tool. Patient-based sensitivity, PPV and cure rate were pooled by using a random-effects model.
EVIDENCE SYNTHESIS
Twenty-three studies including 1716 patients were included for quantitative assessment. FCH PET showed a pooled patient-based sensitivity of 93.8% (95% CI: 89.8-96.3) and PPV of 97% (95% CI: 92.8-98.8) in patients with pHPT. Parathyroid surgery was performed in 1129 patients. The pooled cure rate of PET-guided surgery was 92.8% (95% CI: 87.4-96.0). Heterogeneity was shown to be moderate for all effect sizes.
CONCLUSIONS
FCH PET showed a high patient-based sensitivity, PPV and cure rate of PET guided surgery in patients with pHPT.

Comparison of 4D computed tomography and F-18 fluorocholine PET for localisation of parathyroid lesions in primary hyperparathyroidism: A systematic review and meta-analysis.
Minimally invasive parathyroidectomy (MIP) is the standard of care for primary hyperparathyroidism (PHPT). Four dimensional computed tomography(4DCT) and F-18 Fluorocholine positron emission tomography/computed tomography (FCH PET/CT) localize adenomas accurately to perform MIP. We aimed to conduct a systematic review and metanalysis to evaluate the diagnostic performance of 4DCT and FCH PET/CT scan for quadrant wise localisation in PHPT patients and to do head-to-head comparison between these two modalities. DESIGN, PATIENTS AND MEASUREMENT : After searching through PubMed and EMBASE databases, 46 studies (using histology as a gold standard) of 4DCT and FCH PET/CT were included. RESULTS: Total number of patients included were 1651 and 952 for 4DCT scan (studies n = 26) and FCH PET/CT scan (studies n = 24) respectively. In per patient analysis, FCH PET/CT and 4DCT had pooled sensitivities of 92% (88-94) and 85% (73-92) respectively and in per lesion analysis, 90% (86-93) and 79% (71-84), respectively. In the subgroup with negative conventional imaging/persistent PHPT, FCH PET/CT had comparable sensitivity to 4DCT (84% [74-90] vs. 72% [46-88]). As per patient wise analysis, FCH PET/CT had better detection rates than 4DCT ([92.4 vs. 76.85], odds ratio -3.89 [1.6-9.36] p = .0024) in the subpopulation where both FCH PET/CT and 4DCT were reported. CONCLUSION: Both 4DCT and FCH PET/CT scan performed well in newly diagnosed patients, patients with persistent disease and in those with inconclusive conventional imaging results. FCH PET/CT scan had a higher pooled sensitivity than 4DCT in detecting patients with PHPT in head to head comparison.

Meta-Analysis
OBJECTIVE
To review diagnostic imaging modalities for parathyroid cystic adenomas (PCA). Since PCAs are a rare (0.5%-1%) subclass of parathyroid adenomas, and due to their cystic component, imaging modalities known to be efficient for diagnosing solid adenomas might fail in localizing them.
METHODS
We conducted a systematic review using the PubMed and Cochrane databases for English articles on PCAs published between 1995 and 2020. A meta-analysis of the retrieved data was performed.
RESULTS
Overall, 39 studies, reporting on a total of 160 patients, were included in the analysis. Two thirds (68%) of the patients were female, with a mean age of 53.9 years. A single cystic adenoma was detected in 98.1% of cases. The mean blood calcium corrected for albumin level was 12.6 ± 2.7 mg/dL, and the mean parathyroid hormone level was 565.5 ± 523.8 pg/mL. The mean PCA sizes as measured by ultrasound (US), computed tomography (CT), and ex vivo measurement were 4.8 ± 3.6, 5.2 ± 3.2, and 3.5 cm, respectively. The median weight was 8.1 g. PCA was detected in 86% of US examinations; 100% of US-guided fine needle aspiration, 4-dimensional computed tomography (4D-CT), or magnetic resonance imaging examinations; and 61% of 99m-technetium sestamibi scan with single-photon emission computed tomography ((99m)Tc-SPECT). (99m)Tc-SPECT showed a significantly lower diagnostic rate than US (odds ratio, 3.589), US-guided fine needle aspiration, CT combined with 4D-CT, and the combination of US, CT, 4D-CT, and magnetic resonance imaging (P < .001).
CONCLUSION
Although US and 4D-CT showed a significantly high rate in diagnosing PCA, (99m)Tc-SPECT showed a lower PCA diagnostic rate. These findings suggest that larger cystic lesions suspected as PCAs should be further evaluated using 4D-CT rather than (99m)Tc-SPECT.

OBJECTIVE
Primary hyperparathyroidism is a common disorder of the parathyroid glands. Parathyroid adenoma (PA) in pregnancy is a relatively rare disease, whose diagnosis and treatment is a challenging task. The aim of the present study is to present a new case of parathyroid adenoma during pregnancy and to give a detailed account of all reported cases of parathyroid adenoma during pregnancy in the literature.
STUDY DESIGN
A bibliographic research was performed, and characteristics of parathyroid adenomas in pregnancy such as age, gestational week at diagnosis, ionized calcium levels, genetic testing result, symptomatology, radiological method of localization, treatment method, gestational week at operation, and maternal/fetal complications were recorded.
RESULTS
A 34-year-old woman at her 25 weeks' gestation was diagnosed with parathyroid adenoma and was referred to our Surgical Department due to contraindication for conservative treatment. A parathyroidectomy was performed, and the maternal and fetal postoperative period was uneventful. Two hundred eleven cases of parathyroid adenoma in pregnancy were recorded in the literature, and statistical analysis was performed. The median gestational week at diagnosis was 21 ± 9.61 weeks. The mean level of ionized calcium was 2.69 mmol/l [SD = 0.75 (2.55-2.84 95% CI)]. Most cases were familiar (72.4%), while surgery was the preferred treatment option (67.3%). The majority of cases were asymptomatic (21.7%), and the main radiological method applied for localization was ultrasound (63.4%).
CONCLUSION
Parathyroid adenoma in pregnancy is a rare condition. The early diagnosis is of great importance as surgical treatment at the second trimester of pregnancy outweighs the maternal and fetal risks.

The approach utilized a systematic review of the medical literature executed with specifically designed criteria that focused on the etiologies and pathogenesis of hypoparathyroidism. Enhanced attention by endocrine surgeons to new knowledge about parathyroid gland viability are reviewed along with the role of intraoperative parathyroid hormone (ioPTH) monitoring during and after neck surgery. Nonsurgical etiologies account for a significant proportion of cases of hypoparathyroidism (~25%), and among them, genetic etiologies are key. Given the pervasive nature of PTH deficiency across multiple organ systems, a detailed review of the skeletal, renal, neuromuscular, and ocular complications is provided. The burden of illness on affected patients and their caregivers contributes to reduced quality of life and social costs for this chronic endocrinopathy. © 2022 The Authors.

Meta-Analysis
BACKGROUND
Postsurgical hypoparathyroidism (PH) is the most frequent complication after thyroid surgery. The aim of this systematic review and meta-analysis is to summarize a unifying definition of PH and to elucidate the best possible approach for early detection of PH.
METHODS
A systematic review of the literature according to the PICO framework using Embase, PUBMED and the Cochrane library was carried out on 1 December 2021 followed by analysis for risk of bias, data extraction and meta-analysis. All studies addressing the definition of postoperative hypoparathyroidism and/or diagnostic approaches for early detection and diagnosis were included. Case reports, commentaries, non-English articles, book chapters and pilot studies and reviews were excluded.
RESULTS
From 13 704 articles, 188 articles were eligible for inclusion and further analysis. These articles provided heterogeneous definitions of PH. Meta-analysis revealed that postoperative measurements of parathormone (PTH) levels have a higher sensitivity and specificity than intraoperative PTH measurements to predict PH after thyroid surgery. None of the timeframes analysed after surgery within the first postoperative day (POD1) was superior to predict the onset of PH. PTH levels of less than 15 pg/ml and less than 10 pg/ml are both reliable threshold levels to predict the postoperative onset of PH. A relative reduction of mean(s.d.) PTH levels from pre- to postoperative values of 73 (standard deviation 11) per cent may also be predictive for the development of PH. The estimation of calcium levels on POD1 are recommended.
CONCLUSION
PH is best defined as an undetectable or inappropriately low postoperative PTH level in the context of hypocalcaemia with or without hypocalcaemic symptoms. PTH levels should be measured after surgery within 24 h. Both threshold levels below 10 and 15 pg/ml or relative loss of PTH before/after thyroid surgery are reliable to predict the onset of PH.

Meta-Analysis
BACKGROUND
Hypocalcaemia is a common complication after thyroidectomy. Bariatric surgery is associated with significant changes in calcium metabolism. Some studies have identified bariatric surgery as a risk factor for hypocalcaemia after thyroidectomy. This systematic review and meta-analysis assessed whether a history of bariatric surgery was associated with an increased risk of hypocalcaemia after thyroidectomy.
METHODS
This prospectively registered systematic review (PROSPERO; CRD42021295423) was performed in accordance with PRISMA guidelines. Meta-analysis was undertaken using the Mantel-Haenszel method, with outcomes reported as ORs with 95 per cent confidence intervals.
RESULTS
Twenty studies were included in the qualitative synthesis. Five studies incorporating 19 547 patients met the inclusion criteria for meta-analysis, of whom 196 (1.0 per cent) had a history of bariatric surgery. Patients with a history of bariatric surgery were more likely to develop hypocalcaemia after thyroidectomy (30.6 versus 13.0 per cent; OR 3.90, 95 per cent c.i. 1.50 to 10.12; P = 0.005). Among those with a history of bariatric surgery, patients who underwent a bypass procedure were more likely to develop hypocalcaemia after thyroidectomy than those who had a restrictive procedure (38 versus 23 per cent; OR 2.12, 1.14 to 3.97; P = 0.020).
CONCLUSION
Patients with a history of bariatric surgery have a significantly greater risk of hypocalcaemia after thyroidectomy, with a heightened risk among those who have had a bypass procedure. Surgeons performing thyroid surgery should be aware of the increased risk of hypocalcaemia after thyroidectomy among these patients.

Review
Thyroid cancer is the most common endocrine malignancy with an increasing incidence over the past few years. Surgery is considered the primary therapeutic option, which often involves lymph node dissection. The aim of this study was to assess the role of carbon nanoparticles, a novel agent, in thyroid cancer surgery. For that purpose, we conducted a systematic review of the literature on MEDLINE, EMBASE, Scopus, Cochrane and Google Scholar databases from 1 January 2002 to 31 January 2022. Ultimately, 20 articles with a total number of 2920 patients were included in the analysis. The outcome of the analysis showed that the use of carbon nanoparticles is associated with a higher number of harvested lymph nodes (WMD, 1.47, 95% CI, 1.13 to 1.82, p < 0.001) and a lower rate of accidental parathyroid gland removal (OR 0.34, CI 95% 0.24 to 0.50, p < 0.001). Based on these results, we suggest that carbon nanoparticles are applied in thyroid cancer surgery on a wider scale, so that these findings can be confirmed by future research on the subject.
