Acute abdomen in the immunocompromised patient: WSES, SIS-E, WSIS, AAST, and GAIS guidelines.

Immunocompromised patients are a heterogeneous and diffuse category frequently presenting to the emergency department with acute surgical diseases. Diagnosis and treatment in immunocompromised patients are often complex and must be multidisciplinary. Misdiagnosis of an acute surgical disease may be followed by increased morbidity and mortality. Delayed diagnosis and treatment of surgical disease occur; these patients may seek medical assistance late because their symptoms are often ambiguous. Also, they develop unique surgical problems that do not affect the general population. Management of this population must be multidisciplinary.This paper presents the World Society of Emergency Surgery (WSES), Surgical Infection Society Europe (SIS-E), World Surgical Infection Society (WSIS), American Association for the Surgery of Trauma (AAST), and Global Alliance for Infection in Surgery (GAIS) joined guidelines about the management of acute abdomen in immunocompromised patients.

Primary thyroid teratoma in adults: A case report and systematic review of the literature.

Extragonadal germ cell tumors are uncommon in adults and only 2-5% of teratomas develop in extragonadal sites. Primary thyroid teratomas represent <0.1% of all primary thyroid gland neoplasms. In the present report, a case of primary thyroid teratoma in a 65-year-old female is described. Furthermore, the current literature regarding patients who were diagnosed with primary thyroid teratoma and underwent surgical resection was systematically reviewed. A total of 15 studies of 27 patients (age range, 17-65 years). Growing mass or neck swelling were the primary symptoms in 14 patients (51.8%). Only one (5.5%) patient was preoperatively diagnosed with malignant thyroid teratoma. All patients underwent thyroidectomy, but 6 cases had more advanced surgery, including lymph node dissection. A total of 12 patients received a combination of adjuvant chemoradiation postoperatively, 10 (45.4%) patients reported recurrence of disease and 8 (29.6%) were postoperatively diagnosed with distant metastases. A total of 9 (39.1%) patients died due to progression of the disease. In conclusion, primary thyroid teratomas are rare and difficult to diagnose preoperatively. In particular, malignant cases are very aggressive tumors with a considerably poor prognosis, even after surgical resection combined with adjuvant chemoradiation.

Surgical management of primary hyperparathyroidism during pregnancy: a systematic review of the literature.

OBJECTIVE: Gestational primary hyperparathyroidism (PHPT) is an endocrinological disorder with serious outcomes for both women and neonates. The aim of our study was to present the current evidence concerning the perioperative outcomes of pregnant women with PHPT who underwent parathyroidectomy during pregnancy. METHODS: A meticulous systematic review of the literature published before February 2020 and all studies which presented perioperative and pregnancy outcomes off pregnant women who underwent parathyroidectomy for PHPT, were included. RESULTS: A total of 53 were finally included, which reported 92 pregnant women who had parathyroidectomy during their pregnancy. A total of 46 patients were hospitalized due to significant complications of PHPT before their parathyroidectomy. With regards to surgical approach, 52.2% of patients underwent minimally invasive parathyroidectomy (MIP), while bilateral neck exploration (BNE) was 41.3% of cases. Only 4 women was not cured, whereas transient hypocalcemia was occurred in 18 patients. All cases proceeded to deliveries of healthy neonates, after their parathyroidectomy. CONCLUSIONS: Parathyroidectomy during pregnancy is a safe and effective treatment option with minimum complications and probably should be considered as the treatment of choice in specific group of pregnant women with PHPT.

Duodeno-pancreatic and extrahepatic biliary tree trauma: WSES-AAST guidelines.

Duodeno-pancreatic and extrahepatic biliary tree injuries are rare in both adult and pediatric trauma patients, and due to their anatomical location, associated injuries are very common. Mortality is primarily related to associated injuries, but morbidity remains high even in isolated injuries. Optimal management of duodeno-bilio-pancreatic injuries is dictated primarily by hemodynamic stability, clinical presentation, and grade of injury. Endoscopic and percutaneous interventions have increased the ability to non-operatively manage these injuries. Late diagnosis and treatment are both associated to increased morbidity and mortality. Sequelae of late presentations of pancreatic injury and complications of severe pancreatic trauma are also increasingly addressed endoscopically and with interventional radiology procedures. However, for moderate and severe extrahepatic biliary and severe duodeno-pancreatic injuries, immediate operative intervention is preferred as associated injuries are frequent and commonly present with hemodynamic instability or peritonitis. The aim of this paper is to present the World Society of Emergency Surgery (WSES) and American Association for the Surgery of Trauma (AAST) duodenal, pancreatic, and extrahepatic biliary tree trauma management guidelines.
