Article Synopsis
  • * The study reviewed 19 patients, predominantly experiencing hypoglycemia, with tumor locations identified in 74% of cases via CT and 88% via intraoperative ultrasound, and the most common surgical procedure was enucleation (53%).
  • * The findings suggest that accurately locating insulinomas is vital for the right surgical approach, with enucleation recommended for suitable patients due to its higher success rates and lower serious morbidity, despite a higher occurrence of pancreatic fistulas.

Background/purpose: It is known that COVID-19 patients show many clinical oral symptoms due to the immunological mechanisms triggered by the virus. Aim of this study is to analyze the antibody response to SARS-CoV-2, and to evaluate the oral health status of hospitalized patients.

Materials And Methods: 160 patients with COVID-19 confirmed by SARS-CoV-2-specific RT-PCR testing and 160 healthy volunteers (HI) with similar age, gender and systemic status were included to compare the bio-chemical and oral manifestations.

Von Hippel-Lindau (VHL) disease is an autosomal dominant syndrome and affects many organs. We aim to report an adult patient with VHL disease having bilateral adrenal pheochromocytoma and multiple neuroendocrine tumors of the pancreas who was successfully treated with simultaneous function-preserving adrenalectomy and pancreatectomy. A 27-year-old woman was admitted to hospital with hypertension.

Objective: Fournier's gangrene (FG) is a rare and serious disorder which is associated with high mortality. In the literature, there is no study evaluating clinician-, patient- and disease-related factors affecting disease outcomes according to aetiological variation in FG. In our study, laboratory results and Uludag Fournier's Gangrene Severity Index (UFGSI) score, clinical characteristics and mortality rates were compared between FG originating from perianal or from urogenital regions.

Article Synopsis
  • Inadequate closure of the thyroglossal tract can lead to the development of a thyroglossal duct cyst (TDC), which is often benign but can rarely be malignant.
  • A 39-year-old woman presented with a neck mass that exhibited signs of malignancy during screening, leading to a fine needle aspiration biopsy that did not yield conclusive results.
  • Following excision of the cyst using the Sistrunk procedure, the frozen examination revealed primary papillary carcinoma, necessitating a total thyroidectomy to ensure complete removal of cancerous tissue.

Endoscopic submucosal dissection (ESD) and endoscopic mucosal dissection (EMD) are recognized treatment procedures for mucosal lesions. There will always be a risk for complications even if they are performed by experienced specialists. In this study, we aimed to present a 58-year-old male patient in whom lesion was detected in the proximal part of the descending colon during a colonoscopy.

Objectives: Primary hyperparathyroidism (PHPT) is a common endocrine disease. Ectopic adenomas may cause a failed surgery which results in persistence or recurrence. Intrathyroidal parathyroid adenoma (ITPA) is a rare reason for PHPT and site of ectopia.

Objectives: Concomitant thyroid disease affects almost half of the primary hyperparathyroidism (PHPT) patients. Pre-operative evaluation of the thyroid gland for the early diagnosis of thyroid carcinoma is essential in PHPT patients. Herein, we aim to investigate the clinicopathologic features that affect the type and extent of surgery in patients having PHPT and concomitant thyroid disease but especially thyroid cancer.

Background: Gastrointestinal stromal tumors (GISTs) are the most common mesencyhmal tumors of the gastrointestinal tract. Today surgical resection is still the treatment of choice for primary gastric GISTs. This study compares the laparoscopic versus open surgical resection approaches of gastric GISTs.

Objectives: Although cervical incisions are usually sufficient in mediastinal located thyroid and parathyroid pathologies, sometimes mediastinal approaches are required. In recent years, less invasive methods have been used instead of median sternotomy. In this study, the adequacy of the incision and morbidity in patients who underwent split sternotomy due to retrosternal goiter (RG) and mediastinal parathyroid pathology in our clinic were investigated.

Background: Accurate preoperative localization of the culprit gland is the key point for the surgical treatment of primary hyperparathyroidism. Conventional imaging techniques (ultrasound and Tc99m sestamibi scintigraphy) are usually adequate for preoperative localization. However, in some patient groups, additional imaging modalities may be required since noninvasive techniques may fail.

Objectives: Gastric cancer is the fifth most common cancer and the third most common cause of cancer-related deaths in the world. In this study, we aimed to evaluate the impact of clinicopathological factors on overall survival in the patients who underwent curative-intent gastrectomy due to gastric adenocarcinoma.

Methods: The medical records of 644 patients who underwent gastrectomy between January 2007 and January 2017 in our clinic were retrospectively reviewed.

Purpose: Recurrent laryngeal nerve (RLN) paralysis is one of the most devastating complications after thyroidectomy. Thyroid reoperation is a great challenge for surgeons due to anatomical distortion and fibrosis and associated with a higher risk of RLN injury. In this study, we aimed to compare stimulating dissector (SD) with intermittent stimulating probe (ISP) in thyroid reoperations.

Purpose: The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic.

Aim: Parathyroid surgery has witnessed a significant evolution with the introduction of more efficacious preoperative localization imaging techniques and the use of rapid intraoperative parathormone assays. Parathyroid surgery can now be performed with the minimum of invasion. Through the adaptation of the transoral endoscopic thyroidectomy vestibular approach (TOETVA), the technique has now been adopted for parathyroid surgery, known as the transoral endoscopic parathyroidectomy vestibular approach (TOEPVA).

The 2019 novel coronavirus disease (COVID-19) was initially seen in Wuhan, China, in December 2019. World Health Organization classified COVID-19 as a pandemic after its rapid spread worldwide in a few months. With the pandemic, all elective surgeries and non-emergency procedures have been postponed in our country, as in others.

Primary hyperparathyroidism (pHPT) in pregnancy is a rare entity associated with increased maternal and fetal mortality and morbidity. Diagnosis of pHPT is challenging in pregnancy. Approximately 80% of the cases are asymptomatic, while the most common symptoms are nausea, vomiting, polyuria, polydypsia, and cloudy vision in symptomatic patients.

Background: Hyperparathyroidism (PHP) is the most common cause of hypercalcemia in outpatients. It is characterized by many cardiac complications including chronic cardiac arrhythmia, hypertrophy, and diastolic insufficiency. However, there are insufficient data about the cardiac systolic function in PHP.

Objectives: The selection of incision type, closure type of incision and the suture material are some of the important factors to prevent hernia development. We should aim to perform the best procedure with the best technique to reduce the risk of recurrence. Surgical options include primary repair and open or laparoscopic repair with mesh.

Background: Iatrogenic biliary tract injury (BTI) is a rare complication but has high risks of morbidity and mortality when it is not early noticed. Although the treatment varies depending on the size of injury and the time until the injury is noticed, endoscopic and percutaneous interventions are usually sufficient. However, it should be remembered that these interventions may cause major complications in the following years, such as biliary stricture, recurrent episodes of cholangitis and even cirrhosis.
