Upper Mediastinal Lymphadenectomy Utilizing Prone-Position Thoracoscopy for Esophageal and Gastroesophageal Junction Cancers.

Esophagectomy is the mainstay of treatment in esophageal cancer. Minimally invasive esophagectomy (MIE) remains a challenging procedure and has been associated with a high rate of complications and mortality. Routine lymphadenectomy includes two-field lymphadenectomy for distal-esophageal or gastroesophageal junction Siewert I-II tumors.

Laparoscopic Transduodenal Ampullectomy for a High-Grade Dysplasia Tumor.

Ampullary tumors occur rarely, and the only curative treatment is resection. The endoscopic approach is the most well-known and common treatment of choice. Open surgical resection is the usual treatment of choice in cases of unsuccessful endoscopic resection and big tumors.

A Case of a Metastatic Pancreatic Neuroendocrine Tumor: A Surgical Conundrum Wrapped in Functionality's Embrace.

This case study reports a rare case of a non-functioning metastatic pancreatic neuroendocrine tumor (pNET) transforming into a functioning pNET. A 59-year-old male, previously treated with distal pancreatectomy, splenectomy, lymph node dissection, liver metastasectomy, and pharmacotherapy, presented with weakness, hypoglycemia, and daily episodes of watery diarrhea. A functioning neuroendocrine liver metastasis expressing insulin and gastrin was identified.

Current aspects in the management of esophageal trauma: a systematic review and proportional meta-analysis.

Trauma-related esophageal injuries (TEIs) are a rare but highly lethal condition. The presentation of TEIs is very diverse depending on the location and mechanism of injury (blunt vs. penetrating), as well as the presence or absence of concurrent injuries.

Clinical and Oncological Impact of the Toll-like Receptor-3 and -4 in Esophageal and Gastro-esophageal Junction Adenocarcinoma.

Background/aim: Esophageal and gastro-esophageal junction cancer is a major cause of cancer-related mortality, with poor prognosis. Toll-like receptors (TLRs) play a significant role in the innate immune system; their increased expression has been associated with esophageal adenocarcinoma. This study aimed to determine the association between TLR-3 and TLR-4 expression with clinical and oncological outcomes of patients that underwent esophagectomy for cancer.

The Role of TLR4 in the Immunotherapy of Hepatocellular Carcinoma: Can We Teach an Old Dog New Tricks?

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and is a leading cause of cancer-related death worldwide. Immunotherapy has emerged as the mainstay treatment option for unresectable HCC. Toll-like receptor 4 (TLR4) plays a crucial role in the innate immune response by recognizing and responding primarily to bacterial lipopolysaccharides.

Impact of Minimally Invasive Intrathoracic Hand-sewn Esophago-gastric Anastomosis in Esophagectomy for Cancer.

Background/aim: Ivor Lewis esophagectomy is considered the gold standard approach for the treatment of distal esophageal and gastro-esophageal junction Siewert I-II tumors. Minimally invasive esophagectomy has provided improved outcomes compared to the open approach, offering reduced morbidity, and improved clinical and oncological outcomes. This is the largest study so far reporting the impact of hand-sewn esophago-gastric anastomosis in the prone position, during the 2-stage totally minimally invasive esophagectomy.

Bacterial Translocation as a Source of Postoperative Fever After Revision of a Previous Duodenal Switch for Super-morbid Obesity: A Case Report.

Bacterial translocation is defined as the invasion of gut bacteria or bacterial products to the systemic circulation via permeation through the gastrointestinal mucosal wall. In this article, we present the case of a patient with postoperative fever of unknown origin which was attributed to bacterial translocation after revisional surgery due to malabsorptive complications after an initial duodenal switch for super-morbid obesity.

A Huge Asymptomatic Urachal Mucinous Cystic Carcinoma: A Case Report With Differential Diagnosis and Surgical Considerations.

Cystic mucinous neoplasms of urachal origin cover a wide spectrum of benign and malignant lesions arising from the remnants of the urachus. They display various degrees of tumor cell atypia and local invasion, with no reported cases of metastasis or recurrence after complete surgical resection. We present a 47-year-old man who referred to our Surgical Department due to an abdominal cystic mass incidentally found upon abdominal ultrasound.

Tissue classification and diagnosis of colorectal cancer histopathology images using deep learning algorithms. Is the time ripe for clinical practice implementation?

Colorectal cancer is one of the most prevalent types of cancer, with histopathologic examination of biopsied tissue samples remaining the gold standard for diagnosis. During the past years, artificial intelligence (AI) has steadily found its way into the field of medicine and pathology, especially with the introduction of whole slide imaging (WSI). The main outcome of interest was the composite balanced accuracy (ACC) as well as the F1 score.

A rare cause of tracheopleural fistula following minimally invasive oesophagectomy.

Totally minimally invasive oesophagectomy (TMIE) has been utilised to reduce respiratory and cardiac complications, offering favourable clinical and oncological outcomes. A 62-year-old male patient underwent two-stage TMIE for a Siewert type I tumour. During thoracoscopic oesophageal mobilisation and lymphadenectomy, a 10-mm bone-like mass was recognised and dissected along the subcarinal nodes, revealing a 2-3mm opening on the inferomedial aspect of the right main bronchus.

Individualized Approach in the Surgical Management of Hepatocellular Carcinoma: Results from a Greek Multicentre Study.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer and the third leading cause of death worldwide. The management of HCC is complex, with surgical treatment providing long-term survival in eligible patients. This study aims to present the experience of aggressive surgical management of HCC in Greece.

The Role of Toll-like Receptors in Esophageal Cancer.

Esophageal adenocarcinoma (AC) develops through Barrett's esophagus (BE) and columnar dysplasia, preceded by gastro-esophageal reflux disease (GERD). Incidence of esophageal squamous cell carcinoma (SCC) is increased with tobacco smoking and alcohol abuse. Toll-like receptors (TLRs) can act as prognostic factors and potential therapeutic targets of esophageal cancer.

Role and Efficacy of Robotic-assisted Radical Antegrade Modular Pancreatosplenectomy (RAMPS) in Left-sided Pancreatic Cancer.

Distal pancreatectomy with splenectomy is the gold-standard surgery for the treatment of left-sided pancreatic cancer. Margin negative resection accompanied by effective lymphadenectomy are the deciding factors affecting the outcome of tail-body pancreatic adenocarcinoma. Radical antegrade modular pancreatosplenectomy (RAMPS) is considered as a reasonable approach for margin-negative and systemic lymph node clearance.

Growth of Intestinal Neomucosa on Pedicled Gastric Wall Flap, a Novel Technique in an Animal Model.

Short bowel syndrome (SBS) remains an unsolved issue in modern medicine. Numerous experimental surgical techniques have been proposed in the attempt to increase the intestinal absorptive capacity. Ten female Landrace pigs, divided in two groups of 5 (A and B), were explored through a midline incision.

Minimally Invasive Transcervical Esophagectomy With Mediastinal Lymphadenectomy for Cancer. A Comparison With Standardized Techniques.

Pulmonary complications remain the most common problem following transthoracic esophagectomy. Minimally invasive approach has significantly improved clinical outcomes; however, respiratory distress is still significant. Minimally invasive transcervical esophagectomy with mediastinal lymphadenectomy avoids thoracic access, which may decrease pulmonary complications.

Revision of Roux-en-Y Gastric Bypass for Inadequate Weight Loss or Weight Regain.

Inadequate weight loss or weight regain after Roux-en-Y gastric bypass (RYGBP) occurs in more than a quarter of patients for various reasons. Available remedying treatment options include endoscopic and surgical techniques for revision of the gastric pouch and the gastro-jejunal anastomosis, conversion of standard to distal gastric bypass (DRYGBP) or the conversion of RYGBP to biliopancreatic diversion (BPD) or duodenal switch (DS). There is quite a variability concerning the technical simplicity, safety, and effectiveness of these techniques and the small number of patients in the numerous single-center reports precludes any meaningful comparisons.

Feasibility and Short-Term Outcomes of Three-Dimensional Hand-Sewn Esophago-Jejunal Anastomosis in Completely Laparoscopic Total Gastrectomy for Cancer.

Laparoscopic total gastrectomy is on the rise. One of the most technically demanding steps of the approach is the construction of esophago-jejunal anastomosis. Several laparoscopic anastomotic techniques have been described, like linear stapler side-to-side or circular stapler end-to-side anastomosis; limited data exist regarding hand-sewn esophago-jejunal anastomosis.

30-Day Morbidity and Mortality of Bariatric Surgery During the COVID-19 Pandemic: a Multinational Cohort Study of 7704 Patients from 42 Countries.

Background: There are data on the safety of cancer surgery and the efficacy of preventive strategies on the prevention of postoperative symptomatic COVID-19 in these patients. But there is little such data for any elective surgery. The main objectives of this study were to examine the safety of bariatric surgery (BS) during the coronavirus disease 2019 (COVID-19) pandemic and to determine the efficacy of perioperative COVID-19 protective strategies on postoperative symptomatic COVID-19 rates.

An extraordinary rare anastomotic band causing food bolus obstruction following uneventful minimally invasive esophagectomy: endoscopic treatment.

The most common long-term complication post esophagectomy implicating the esophagogastric anastomosis is stricture-induced stenosis leading to late postoperative dysphagia. Herein, we present a case of a male patient readmitted to our Upper Gastrointestinal Department due to a food bolus obstruction through an anastomotic epithelial band arisen from a prior esophagogastric anastomosis performed 5 months earlier. A band transection in between two hemostatic clips placed on both sides of the band, followed by a release and fragmentation of the foreign body into several pieces led to its final transoral removal endoscopically.
