Reclassification of Appendiceal Mucinous Neoplasms and Associated Pseudomyxoma Peritonei According to the Peritoneal Surface Oncology Group International Consensus: Clinicopathological Reflections of a Two-Center Cohort Study.

Background: International consensus on classifications of appendiceal mucinous neoplasms (AMNs) and associated pseudomyxoma peritonei (PMP) have been carefully made but clinicopathological associations supporting decision making remain scarce.

Objective: This study aimed to assess interdependence between AMNs and PMP and provide directions for clinical management.

Methods: This two-center retrospective cohort study reviewed patients with PMP treated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy between 2005 and 2021.

An observational cohort of patients with colorectal peritoneal metastases or pseudomyxoma peritonei treated with CRS-HIPEC: Development and first results of the Dutch CRS-HIPEC quality registry.

Introduction: To improve care for patients with colorectal peritoneal metastases (CRC-PM) or pseudomyxoma peritonei (PMP), the Dutch CRS-HIPEC quality registry was initiated in 2019. The aims are to describe the development and content of this registry and to give insight into the data collected during the first years.

Materials And Methods: The registry is an observational cohort in the Netherlands.

A new surgical technique: robotic intracorporeal Kono-S anastomosis in Crohn's - a safety and feasibility case series on short-term outcomes.

Aim: The Kono-S anastomosis was introduced as a possible solution to the high surgical recurrence rates in Crohn's disease. However, this technique is known to be challenging, which is why it was originally performed in an extracorporeal setting. The aim of this case series was to assess safety, in terms of intra-/postoperative complications, and feasibility, in terms of successful performance of anastomosis, of a robot-assisted intracorporeal Kono-S anastomosis.

Use of ileostomy versus colostomy as a bridge to surgery in left-sided obstructive colon cancer: retrospective cohort study.

Background: Colorectal cancer causes the majority of large bowel obstructions and surgical resection remains the gold standard for curative treatment. There is evidence that a deviating stoma as a bridge to surgery can reduce postoperative mortality rate; however, the optimal stoma type is unclear. The aim of this study was to compare outcomes between ileostomy and colostomy as a bridge to surgery in left-sided obstructive colon cancer.

Prediction of Non-Response to Neoadjuvant Chemoradiotherapy in Esophageal Cancer Patients with F-FDG PET Radiomics Based Machine Learning Classification.

Background: Approximately 26% of esophageal cancer (EC) patients do not respond to neoadjuvant chemoradiotherapy (nCRT), emphasizing the need for pre-treatment selection. The aim of this study was to predict non-response using a radiomic model on baseline F-FDG PET.

Methods: Retrospectively, 143 F-FDG PET radiomic features were extracted from 199 EC patients (T1N1-3M0/T2-4aN0-3M0) treated between 2009 and 2019.

The immediate impact of the coronavirus disease 2019 (COVID-19) pandemic on burn-out, work-engagement, and surgical training in the Netherlands.

Background: The coronavirus disease 2019 pandemic led to major changes in health care and education options for all health care employees. The aim of this study is to achieve insight into coronavirus disease-care participation of surgical residents in the Netherlands, the impact of coronavirus disease 2019 on the experienced quality of surgical training, and the influence on Burn-out and Work Engagement compared with the non-coronavirus disease 2019 period in January 2020.

Methods: In this study, we have conducted 2 digital surveys immediately before and 2 months after the start of the coronavirus disease 2019 pandemic.

Blunt abdominal injury resulting in a belly full of candy after a motocross accident, a case report.

Background: Blunt traumatic gastric perforations in children are rare. Delayed diagnosis will lead to abdominal contamination and may result in morbidity and even mortality. We present a case of an adolescent who sustained blunt abdominal injury in a motocross accident and presented with remarkable hyperdense spherical shaped structures on the computed tomography (CT).

Malignant Transformation of an HNF1a-Inactivated Hepatocellular Adenoma to Hepatocellular Carcinoma.

Hepatocellular adenomas (HCA) are rare benign tumors of the liver, occurring predominantly in females using oral contraceptives. Our case describes a 66-year-old woman presenting with a palpable mass in her upper abdomen. Contrast-enhanced computed tomography and magnetic resonance imaging showed a large exophytic mass protruding from the caudal border of liver segments IV and V, without visible metastases.

Intestinal obstruction caused by pericecal internal herniation.

Intestinal obstruction caused by pericecal internal herniation are rare and only described in a few cases This case describes an 80-year-old man presented with acute abdominal pain, nausea and vomiting, with no prior surgical history. Computed tomography was performed and showed a closed loop short bowel obstruction in the right lower quadrant and ascites. Laparoscopy revealed pericecal internal hernia.

Two versus five days of antibiotics after appendectomy for complex acute appendicitis (APPIC): study protocol for a randomized controlled trial.

Background: Acute appendicitis is one of the most common indications for emergency surgery. In patients with a complex appendicitis, prolonged antibiotic prophylaxis is recommended after appendectomy. There is no consensus regarding the optimum duration of antibiotics.

Five-Year Outcome of Self-Expanding Covered Stents for Superficial Femoral Artery Occlusive Disease and an Analysis of Factors Predicting Failure.

Purpose: To investigate the 5-year outcome of patients treated with self-expanding covered stents for superficial femoral artery (SFA) occlusive disease and identify parameters that could predict loss of primary patency.

Methods: In a dual-center study, 315 consecutive patients (mean age 69.0±10.

A traumatic superficial temporal artery aneurysm after a bicycle accident.

A male cyclist presented with a swelling on the forehead. Six weeks before, he fell of his bike and smashed his head on the ground while wearing a helmet. A smooth lump of 1 cm had evolved on the temporal side of his forehead in a few weeks.
