Achalasia is a mortality disorder described in 1674 by Willis. It has a small incidence in the general population. The main symptom is dysphagia. The golden standard for diagnosis is esophageal manometry. Esophageal scintigraphy is a non-invasive method of exploration: the technique is simple, it lasts five minutes and is more sensitive than the radiologic exam. The esophageal scintigraphy was made in the Nuclear Medicine Laboratory of the Sf. Spiridon Hospital using a gamma scann Diacam--Siemens. The parameters measured with esophageal scintigraphy are: esophageal transit time, residuary radioactivity. Our study included a number of 37 patients with achalasia with ages between 16 and 80 years (the average--47, 3 years). Our conclusions are the same with the data from literature.

A young man in his 30s presented to us with multiple episodes of syncope and exertional dyspnoea for the last 2 weeks. He was diagnosed with squamous cell carcinoma of the lower one-third of the oesophagus in 2021 for which he was treated with neoadjuvant chemoradiotherapy, followed by McKeown oesophagectomy. At 2-year follow-up, he had developed a soft tissue swelling in the scalp, which was diagnosed as a tumour recurrence and radiotherapy was initiated.

Objective: In systemic sclerosis (SSc), absent contractility (AC) rather than ineffective esophageal motility on manometry is associated with a severe esophageal and extraintestinal phenotype. We sought to determine whether slow esophageal transit on scintigraphy associates with a comparable clinical phenotype to that of AC on manometry, as scintigraphy may serve as a noninvasive approach to risk-stratify patients with SSc.
Methods: Clinical, demographic, and serologic features were compared between patients with and without delayed esophageal transit on scintigraphy.

Background: Esophageal ulcers can arise not only from malignant lesions but also from benign diseases, such as tuberculosis. These ulcers may mimic the radiological features of esophageal malignancy or tuberculosis on PET/CT, leading to diagnostic challenges.
Case Presentation: A 59-year-old woman was admitted to our hospital with a month-long history of progressive painful swallowing, fatigue, and loss of appetite.
Background: This study aimed to compare outcomes following antral preserving (AP) and antral resecting (AR) laparoscopic sleeve gastrectomy (LSG) in terms of weight loss, gastric emptying time, gastroesophageal reflux disease (GERD), resolution of associated medical problems, and complications.
Methods: Patients were prospectively randomized into two groups: the AR group (resection starting 2 cm from the pylorus) and the AP group (resection at 5 cm from the pylorus). Follow-up evaluations included assessments of weight loss using percentage of excess weight loss (%EWL) and percentage of total weight loss (%TWL), gastric emptying, GERD symptoms, associated medical problem resolution, residual gastric volume, and complications.

Background: The clinicoradiological staging for esophageal cancer is fraught with variable accuracy, potentially depriving patients who have been understaged of the benefit of neoadjuvant therapy, which has been shown to improve long-term survival in locally advanced malignancies. It is imperative to identify these high-risk tumors for tailored treatment.
Methods: Retrospective analysis of a prospective database of patients undergoing esophagectomy for carcinoma esophagus between 2011 and 2019.
