Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago.

BACKGROUND: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. METHODS: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. RESULTS: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. CONCLUSIONS: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception.

The Challenge of Pneumatosis Intestinalis: A Contemporary Systematic Review.

PURPOSE: Pneumatosis intestinalis is a radiological finding with incompletely understood pathogenesis. To date, there are no protocols to guide surgical intervention. METHODS: A systematic review of literature, according to PRISMA criteria, was performed. Medline and PubMed were consulted to identify articles reporting on the items "emergency surgery, pneumatosis coli, and pneumatosis intestinalis" from January 2010 up to March 2022. This study has not been registered in relevant databases. RESULTS: A total of 1673 patients were included. The average age was 67.1 ± 17.6 years. The etiology was unknown in 802 (47.9%) patients. Hemodynamic instability (246/1673-14.7% of the patients) was associated with bowel ischemia, necrosis, or perforation (p = 0.019). Conservative management was performed in 824 (49.2%) patients. Surgery was performed 619 (36.9%) times, especially in unstable patients with bowel ischemia signs, lactate levels greater than 2 mmol/L, and PVG (p = 0.0026). In 155 cases, surgery was performed without pathological findings. CONCLUSIONS: Many variables should be considered in the approach to patients with pneumatosis intestinalis. The challenge facing the surgeons is in truly identifying those who really would benefit and need surgical intervention. The watch and wait policy as a first step seems reasonable, reserving surgery only for patients who are unstable or with high suspicion of bowel ischemia, necrosis, or perforation.

Mini-invasive video-assisted thyroidectomy vs robot-assisted transaxillary thryoidectomy: analisys and comparison of safety and outcomes.

Thyroid surgery is characterized by large volumes and typically affects a young female population. Mini-invasive or remote access surgical techniques are born driven by the desire to improve aesthetic outcomes of the traditional technique, following technological advances that have upset the surgical world in the last 20 years. In our multicenter, retrospective observational study, we first compared an endoscopic technique with a robotic one: minimally invasive video-assisted thyroidectomy (MIVAT) and robot-assisted transaxillary thyroidectomy (RATT). We evaluated intraoperative features, complications, and cosmetic outcomes in a cohort of 609 patients. The efficacy and safety of these techniques are proven by a large literature and the comparison made in our study does not show inferiority of one technique compared to the other. Even the aesthetic results tend to be equal in the long term. It is desirable that further prospective and randomized studies are conducted to evaluate the outcomes of these procedures and the cost-benefit ratio.

Malignancy risk in Bethesda class IV thyroid nodules in an iodine deficient region.

Background: According to the latest guidelines, in patients with high-risk nodules with indeterminate cytology, diagnostic lobectomy should be the preferable surgical approach in the absence of factors that suggest a total thyroidectomy. Methods: This retrospective observational study has as its main aim the evaluation of the cases that underwent surgery, for Bethesda class IV nodules in our iodocarent geographical area. Particular attention was paid to carcinoma incidence, preoperative nodule size, histological characteristics of the neoplasm, surgical approach and eventual need of radiometabolic treatment. A total of 320 patients were included that underwent surgery for Bethesda IV nodules, between January 2010 and December 2020, at the General Surgical Clinic of the University Hospital of Parma, Italy. Results: A total of 230 total thyroidectomies (71.9%) and 90 lobectomies (28.1%) were performed. Our data showed a strong impact of the 2015 ATA Guidelines on the surgical approach choice, with a progressive propensity towards a conservative approach and an increase of lobectomies from 7.2% to 41.5% after the new guidelines introduction. However, in our sample the percentage of lobectomies remains below 50%; this data is certainly influenced by the number of cases of multinodular pathology, often bilateral, in our geographical area. The nodules malignancy rate resulted 28.8%. Our data showed that increasing size correlated with an increasing malignancy rate (P<0.01), and follicular carcinomas were found to be larger than papillary carcinomas (P<0.001). A statistically significant correlation also emerged between nodule size increase and local/lymphovascular invasion (P<0.05). On the other hand, there was no statistically significant correlation between nodule size and multifocality, and between nodule size and presence of lymph node metastases. Out of the patients where it was possible to find this data, 66% underwent radioiodiometabolic treatment: 59% with papillary carcinoma, and 85% with follicular carcinoma. Conclusions: In patients with Bethesda IV thyroid nodules, diagnostic lobectomy should be the preferable surgical approach in absence of factors that suggest total thyroidectomy. In our opinion, total thyroidectomy remains the first choice in large nodules (≥4 cm) as these nodules have a high malignancy rate, greater local/lymphovascular invasion and a consequent frequent indication for post-operative radiometabolic treatment.

Conservative management of complicated colonic diverticulitis: long-term results.

BACKGROUND: The management of recurrent diverticulitis after initial non-operative treatment remains controversial. Recurrences after medical treatment have been described up to 36% but only 3 to 5% develop complicated disease. AIM: To investigate the effectiveness of conservative treatment during a prolonged follow-up after first episode of complicated diverticulitis. METHODS: This retrospective single-center study describes the conservative management and outcomes of 207 with complicated acute colonic diverticulitis treated at Parma University Hospital from 1 January 2012 until 31 December 2019. The follow-up was performed until December 2020. Diverticulitis severity was staged according to WSES CT driven classification for acute diverticulitis. RESULTS: We enrolled 207 patients (118 males, 89 females). The mean age was 59 ± 14.5 years. CT scan of the abdomen was always performed. Almost all patients were treated with bowel rest and antibiotics (98.5%). Percutaneous drainage of abscessed diverticulitis was performed 12 times (5.7%). Average follow-up was 48 ± 28.8 months. 79 patients had new episodes of diverticulitis (38.1%) and 23 patients had high severity new episodes (11.1%). 11 patients underwent surgery (7.7%). Lower CT-Stages showed a higher recurrence rate (P = 0.002). Grade III diverticulitis showed a lower recurrence rate (P = 0.007). Patients with chronic NSAID use showed a higher incidence of high severity new episodes (P = 0.039). No recurrence rate differences were noted among patients with or without home therapy (P > 0.05). CONCLUSIONS: Non-operative treatment is an effective and safe option in selected patients with complicated diverticulitis. The recurrence's severity is generally lower than the previous episodes and this can justify the conservative management.

Intraoperative Neuromonitoring, Nerves at Risk and Staged Thyroidectomy, our Experience on 377 Consecutive Cases.

PURPOSE: The aim of this study was firstly to report the experience of intermittent intraoperative neuromonitoring (I-IONM) and evaluate the impact of loss of signal (LOS) in staged thyroidectomy management. METHODS: We retrospectively reviewed patients who underwent total thyroidectomy, performed by a single surgeon in two years. All patients have been subjected to I-IONM. In case of intraoperative loss of signal (LOS), planned total thyroidectomy was always aborted. Six-month follow-up was performed. Postoperative dysphonia was evaluated with VHI-10 score in 3 time settings T1, during hospital stay, T2 after 30 days, T3 after 6 months. Dysphonia has been compared to IONM results to evaluate sensitivity and specificity. RESULTS: 377 patients were included. Incidence of dysphonia was calculated based on the number of nerves at risk (NAR). We evaluated a total of 724 NAR. LOS encountered were 43 cases (5.9% of total NAR), of these 14 were LOS 1 while 29 were LOS 2. 27 patients (3.7% of NAR) presented early post-operative dysphonia with VHI-10 score > 13 (T1), among these 16 had presented LOS at IONM (true positives) while11 had no LOS (false negatives). In T2 and T3 we reported a decrease in true positive cases increasing false positives. Sensitivity at T3 reached 85.7% while specificity and odds ratio were respectively 94.8% and 110. CONCLUSIONS: Given the high sensitivity and specificity, IONM should be considered a useful tool for thyroid surgery and its use should be suggested for patients undergoing planned total thyroidectomy. Its right application may cancel the risk of bilateral paralysis.

Serum 25-hydroxyvitamin D level is unreliable as a risk factor and prognostic marker in papillary thyroid cancer.

Background: Low levels of vitamin D and altered local vitamin D metabolism have been associated with the prevalence and aggressiveness of several cancers. However, the effect of vitamin D on papillary thyroid cancer (PTC) is controversial. This study aimed to evaluate the impact of preoperative serum vitamin D levels and local vitamin D metabolism on the clinicopathologic characteristics and prognosis of PTC. Methods: In total, 1,578 patients with PTC and 128 patients with benign thyroid diseases were included. Clinical and pathologic data were analyzed to evaluate the role of vitamin D as a risk factor and prognostic marker in PTC. Moreover, a tissue microarray was used to investigate the role of local vitamin D metabolism in PTC progression. Results: Participants with PTC were younger compared to those with benign disease. No significant differences in 25-hydroxy vitamin D [25(OH)D] levels were observed between benign and malignant cases. Among patients with PTC, analyses of prognostic features revealed that decreased 25(OH)D levels were not overtly associated with poor prognosis in PTC. Additionally, local vitamin D metabolism was not associated with the aggressiveness of PTC. Conclusions: Serum 25(OH)D determination may not contribute to risk assessment workup of thyroid nodules. Moreover, decreased preoperative serum vitamin D and local vitamin D metabolism were not associated with poor prognosis of PTC.

Intraoperative neuromonitoring in thyroidectomy for carcinoma in a high-volume academic hospital.

BACKGROUND: The diagnosis of thyroid carcinoma has changed in last decades, as the surgical technique during thyroidectomy (endoscopic surgery, robotic surgery, new energy device, intraoperative neuromonitoring). METHODS: We analyzed patients undergone to thyroidectomy or lobectomy for thyroid carcinoma from January 2010 to December 2019 at the General Surgery Unit of the Hospital - University of Parma. We divided patients into two groups, based on the use or not of IONM. RESULTS: We analyzed data about 638 patients, 486 (76.2%) females and 152 (23.8%) males, with a mean age of 51.8 years. Totally, 574 patients underwent total thyroidectomy and lymphadenectomy was performed in 39 patients. The lobectomy rate was higher in interventions with neuromonitoring (13.93%) than in those without IONM (3.06%). Considering the incidence of postoperative complications and the presence of infiltration of perithyroid tissues or thyroiditis or lymph node metastasis at the histological report, a statistically significant percentage of dysphonia and paraesthesia was recorded only in patients with infiltration of perithyroid tissues (P<0.0001). There was no significant difference in postoperative blood calcium values. The use of intraoperative neuromonitoring has not significantly changed the incidence of postoperative complication. CONCLUSIONS: Our study did not show a protective impact of the use of intraoperative neuromonitoring during thyroidectomy on the incidence of postoperative complications but confirmed that it increases the surgeon's feel safety during surgery and facilitates the identification of any undetected nerve lesion with visually intact nerve, inducing the interruption of the thyroidectomy after lobectomy alone, reducing the risk of bilateral recurrent paralysis.

Multifocality in patients treated for papillary Thyroid Carcinoma: a preliminary analysis of related risk factors.

Background Multifocality is usually detected afterwards surgery for papillary thyroid cancer (PTC) and has been reported in 18-87% of PTC. Methods This is a retrospective single-center study involving a series of 238 patients that underwent thyroidectomy or lobectomy after preoperative fine needle aspiration (FNA) diagnosis of Thyr 5 or Thyr 6, according to Bethesda classification, from January 2015 to December 2019 at the General Surgery Unit of the University - Hospital of Parma. We divided patients into two main groups: patients with multifocal papillary thyroid cancer at postoperative diagnosis and patients with unifocal papillary thyroid cancer. The aim of the study is to identify demographic or preoperative radiological risk factors for the presence of multifocal PTC and to verify the presence of cyto-histological features of greater aggressiveness in multifocal tumors than in unifocal ones. Results Out of our sample, 176 patients were females (73,9%) and 62 males (26,1%) with a mean age of 50,45 ±14,41. Preoperative cytological diagnosis resulted Thyr 5 in 47 cases (19,7%) and Thyr 6 in 191 cases (80,3%). Multifocal cancer was reported in 35,8% of the females and in 32,3% of the males. Older age was significatively related to the presence of multifocal papillary carcinoma (p<0.05). Preoperative bilateral thyroid nodules were associated with a higher finding of multifocal disease at histological examination (p<0.05). The presence of multifocal disease was related with a higher soft tissue invasion at the histological specimen (p<0.05).  Tumor size was not related to multifocal PTC in our study. Conclusions Older age of patient and preoperative bilateral thyroid nodules are significantly associated to multifocal thyroid cancer. In add to this, multifocal disease is related to higher finding of perithyroidal tissue invasion at histological exam. In case of predictive factors for multifocal PTC, surgeons should take total/near-total thyroidectomy always into consideration.

Wounds morphologic assessment: application and reproducibility of a virtual measuring system, pilot study.

BACKGROUND AND AIMS: Assessment of wounds morphology can be considered, in the everyday medical activity, the first step for the correct pathway of diagnosis. Authors present a pilot study focused on the statistical analysis of 32 cases of wounds measurements conducted by both the traditional method (paper ruler) both the digital smartphone analysis. MATERIALS AND METHODS: 32 lesions were morphologically evaluated. All the enrolled patients were evaluated by both the traditional method (paper ruler) both a digital smartphone analysis based on the app imitoMeasure. The extracted data were compared to the traditional measurements and a statistical analysis was based on intraclass correlation coefficients (ICC). RESULTS: Three morphological parameters were evaluated: width (expressed in cm), length (expressed in cm) and area (expressed in cm2). The area (expressed in cm2) was found to be the less comparable, but the data were close in this case, too. CONCLUSION: The present study shows that the digital measuring systems should be easily addressed as versatile tools that could be applied in daily clinical practice in the future.

How COVID-19 pandemic has changed elective surgery: the experience in a general surgery unit at a COVID-hospital.

OBJECTIVE: Evaluate the impact of Covid-19 in a critical area and analyze the changes in the daily activities in a General Surgery Unit of a tertiary Covid-Hospital. METHODS: We report and compared all the surgical procedures performed between two periods (March and April 2019 and March and April 2020) at General Surgery Department of Parma University Hospital, a tertiary Covid-Hospital. RESULTS: Between March and April 2019, a total of 232 surgical procedures were performed. Between March and April 2020 only 61 surgical procedures were performed. In 2019 84 patients underwent surgery for cancer and 171 underwent surgery for benign diseases. In 2020 only 37 patients underwent surgery for oncological reasons and 24 underwent surgery for benign diseases. CONCLUSIONS: During pandemic Covid-19 the access to health services was limited and poor. Limited access to health services and the fear of Covid-19 infection can explain the lower number of elective surgical procedures for cancer in 2020 compared to the same period in the 2019.

Relationship between surgeon experience and adverse events in thyroid surgery.

In scientific literature there are numerous authors that have highlighted how the outcome of patients undergoing surgical treatment, such as intraoperative or postoperative complications, surgical time, mean hospital stay, is related to the surgeon's experience based on the number of cases treated per year for a specific disease. In our study we decided to verify if, in our clinical practice, there are significant differences in postoperative outcomes between procedures performed by a senior surgeon, a young specialist or a surgical resident, evaluating if surgical experience affects positively either on intraoperative complications such as bleeding, hypocalcemia, dysphonia, or on surgical time, mean hospital stay and postoperative complications. In this retrospective study we examined all cases of patients that underwent surgery for thyroid disease at our Operative Unit, from January 1, 2015 to December 31, 2019. The analysis of our data highlights how the surgeon's experience affects the surgical outcome of patients undergoing lobectomy or total thyroidectomy. Our conclusion was that a high volume center, like the one we are working in, with a correct selection of the patients,  allows to train a surgical resident guaranteeing both the surgical training of the doctor and the patients safety.

Preoperatory imaging evaluation in primary hyperparathyroidism and associated thyroid disease.

BACKGROUND: Primary hyperparathyroidism (pHPT) is an endocrinological disorder characterized by excessive secretion of parathormone. Minimally invasive approach has become a widespread surgical method for pHPT treatment due to the improvement of preoperative gland localization imaging techniques and the use of intraoperative PTH dosage (IOPTH). We discuss the results of different imaging technique. MATERIALS AND METHODS: We have conducted a retrospective analysis of 80 patients that underwent surgery for primary hyperparathyroidism in the period between 01/01/2012 and 28/02/2018 and we have focused our data collection on preoperative study, intraoperative findings and follow-up data. We have evaluated the concordance between the findings of the most used imaging techniques, copresence of thyroid disease and IOPTH. RESULTS: SPECT-CT showed the best results in terms of positivity (93.1%), sensitivity (88.9%) and accuracy (82.8%). Neck ultrasound resulted to have the best positive predictive value (94.4%). IOPTH decrease was correlated with patients' healing (p <0.05). Age lower than 70 years, post-operative calcium and PTH serum levels were related to a higher chance of healing (p <0.05). CONCLUSION: US-scintigraphy combination is suitable for preoperative evaluation and SPECT/CT confirms to be the best additional examination; the presence of thyroid disease decrease the sensitivity. IOPTH is an important predictor of healing KEY WORDS: Intraoperative PTH, Hyperparathyroidism, Parathyroidectomy, SPECT/CT, Thyroid disease.

The modified TIME-H scoring system, a versatile tool in wound management practice: a preliminary report.

BACKGROUND AND AIMS: The concept of WBP (wound bed preparation) has revolutionized the way to diagnose and correctly identify the best therapeutic path about the widespread clinical problem of difficult wounds. Starting from the modified TIME-H, authors conducted a preliminary study with the aim of assessing the impact of skin lesions and soft tissues for the surgical patient. MATERIALS AND METHODS: 38 patients were preliminarily evaluated. The patients were classified according to the lesion examined, in particular among those who had an infectious or vascular etiology (SSTIs), and patients with surgical site lesions (SSI) and assigned to one of three categories prognosis: favorable (with healing expected within 12 weeks) (0-3A, 0-1B), intermediate (with healing expected over 12 weeks) (4-6A, 2-4B) and uncertain healing (7- 8A, 5-8B). RESULTS: At the end of the one-year observation period, authors established the healing prediction rate among the studied lesions: the surgical site lesions presented the highest percentage of predictivity (88%), followed by the mixed etiology (72%) and the infectious/vascular injuries (63%) Conclusion.This modified-TIME-H can be considered as a versatile and useful scoringtool that should be used in daily clinical practice for the study and treatment of chronic wound diseases.

Adverse events in thyroid surgery: observational study in three surgical units with high volume/year.

BACKGROUND: Thyroid surgery, performed for benign or malignant pathologies, is one of the most frequently performed procedures and its frequency has even been increasing in recent years. Postoperative bleeding, recurrent laryngeal nerve (RLN) palsy, associated to dysphonia, dysphagia, dyspnea, and hypoparathyroidism represent the most fearful and common complications. We conducted a multicenter, observational study of retrospectively collected data in three high-volume referral centers, enrolling all patients undergone to thyroid surgery between January 2016 and December 2017 in Parma University Hospital, Cagliari University Hospital and Ferrara University Hospital. MATERIALS: Patients were divided into five groups, differentiated thyroid carcinoma, medullary thyroid carcinoma, non-toxic benign pathology, hyperfunctioning benign pathology and NIFTP (Non-invasive Follicular Thyroid neoplasm with Papillary-like nuclear features). A follow up at 7 and 30 days was executed, evaluating the onset of paresthesia, dysphonia and dysphagia. A 6-month follow-up was conducted in cases of early complications. RESULTS: Totally, 1252 patients were eligible for the study: 907 female and 345 male, with a female to male ratio of 2.6:1 and an average age of 53.428. Total thyroidectomy was performed in 1022 cases, lobectomy in 230. After 6 months we recorded paresthesia in 0.5%, dysphonia in 1.8% and dysphagia in 0.5%. CONCLUSION: Our study confirms once again that a share of morbidity escapes the possibilities of prediction and control by the operator, depending on patient anamnestic, pathological or anatomical factors.

Thyroid nodules with indeterminate cytology: association between nodule size, histopathological characteristics and clinical outcome in differentiated thyroid carcinomas - a multicenter retrospective cohort study on 761 patients.

A great number of surgical diagnostic procedures are performed every year for thyroid nodules that are included in undetermined cytological classes that reveal to be malignant thyroid carcinomas in one-third of cases. In the most recent guidelines, lobectomy is the most recommended surgical approach for this classes of nodules, but total thyroidectomy is the recommended treatment for undetermined nodules larger than 4 cm. The main study aim is to support or question the dimensional criteria as an independent clinical decision element for undetermined thyroid nodules management. We examined data regarding 761 patients undergoing thyroid surgery for undetermined thyroid nodules at two high-volume endocrine surgery units in Italy. Patients were divided into three groups based on the preoperative size of the nodules (N < 1, 1 < N < 4, N > 4 cm). Among the patients belonging to the different groups, we analyzed: differences in malignancy rate, histological characteristics of invasiveness and neoplastic aggressiveness, rates of recurrence and response to therapy. Nodule size (evaluated as a categorical variable and as a continuous variable) did not show any statistically significant correlation with the rate of malignancy, histopathological characteristics of tumor aggressiveness and the patient's clinical outcome. Most of the tumors found were included in the low risk class (79.2%) and only one was classified as high risk. Follow up of cancer cases showed excellent results in terms of survival, response to therapy and disease recurrence. Malignant thyroid tumors of any size resulting from a nodule identified as cytologically indeterminate are usually characterized by a low risk follicular pattern, well-differentiated and with an excellent outcome. As a result, preferring an extended surgical attitude for undetermined nodules based on tumor size, in absence of other risk factors, can lead to overtreatment in a significant percentage of cases.

Open abdomen in the management of complicated diaphragmatic hernia: a case report.

Diaphragmatic hernia (DH) can be congenital or acquired. DH is a potentially life-threatening condition and the management in emergency setting remain unclear. Nonspecific symptoms can delay the diagnosis. We report a case of a 63-year-old man admitted for abdominal pain and nausea. He was successfully treated with damage control surgery.

Cribiform-morular variant of papillary thyroid carcinoma and familial adenomatous polyposis: Report of a case.

Cribiform-morular thyroid carcinoma is a rare variant of papillary thyroid carcinoma. It is usually related to Familial Adenomatous Polyposis (FAP) but rarely it may be sporadic. This variant of PTC occurs in young females and it is rare in the elderly. We report a case of a 20 years old female presenting thyroid carcinoma and personal history of FAP.

Jejunal diverticulitis: Things to know to prevent diagnostic mistake.

We report a peculiar case of jejunal diverticulitis in 54-year-old female. Since hospital admission, a colonic diverticulitis was suspected. CT scan of the abdomen showed multiple fluid collections with free intraperitoneal extraluminal air, suggesting bowel perforation. A complicated acute diverticulitis of the colon was suspected but intraoperatively, a perforated acute diverticulitis of jejunum was detected. The aim of this work is to evidence the key role of CT scan of the abdomen in differential diagnosis of unfrequently pathological entities, such as jejunal diverticulitis, to prevent diagnostic mistakes.

A peculiar manifestation and clinical course of occult primary hyperparathyroidism: a case report.

We present the clinical case of a patient who developed acute hypercalcemia diagnosed after presenting acute pancreatitis.Male patient, age 67, arrived at the Emergency Department of the University Hospital of Parma for upper abdominal pain, radiated to the back, and associated with nausea. Laboratory tests showed elevation of lipase, serum calcium levels, PTH levels and serum creatinine.  Due to the persistence on hypercalcemia an ultrasound scan of the cervical region was performed and showed a hyperechoic nodule of about 25x26x30 mm at the level of the lower pole of the left thyroid lobe, compatible with hyperplastic parathyroid. In the light of clinical-radiological examinations, acute edematous pancreatitis due to hypercalcemia was diagnosed. Hypercalcemia was attributable to primary hyperparathyroidism, so surgical indication to parathyroidectomy was gave.After medical treatment there was a progressive improvement of the clinical conditions and a few days later the patient underwent surgical operation of lower left parathyroidectomy with progressive normalization of the serum calcium levels. If hypercalcemia persists ​​after the beginning of a specific therapy there is an indication to perform an emergency parathyroidectomy; in our case the surgical procedure was performed some days after the diagnosis because the calcium serum levels ​​had returned to normal values with significant improvement of the clinical conditions, despite persistence of high PTH values.
