Article Synopsis
  • Acute appendicitis is a frequent surgical emergency typically caused by blockages in the appendix from fecaliths, tumors, or lymphoid growth.
  • Appendectomy has been the standard treatment since 1883, evolving from open procedures to laparoscopic techniques, but it carries risks and complications, including negative appendectomies.
  • Recent developments in endoscopic technology suggest new, minimally invasive treatments like endoscopic retrograde appendicitis therapy, providing a promising alternative for managing uncomplicated cases of appendicitis.

Article Synopsis
  • The coexistence of Crohn's disease and acute appendicitis is uncommon, presenting challenges in treatment due to differing recommended approaches for each condition.
  • A 17-year-old boy with Crohn's disease experienced symptoms of appendicitis, and after confirmation through ultrasound, he underwent endoscopic retrograde appendicitis therapy (ERAT) rather than a traditional appendectomy.
  • The ERAT procedure was successful, providing immediate pain relief and preventing further abdominal attacks over an 18-month follow-up, indicating it as a safe alternative treatment in patients with both conditions.

Background: Acute iatrogenic colorectal perforation (AICP) is a serious adverse event, and immediate AICP usually requires early endoscopic closure. Immediate surgical repair is required if the perforation is large, the endoscopic closure fails, or the patient's clinical condition deteriorates. In cases of delayed AICP (> 4 h), surgical repair or enterostomy is usually performed, but delayed rectal perforation is rare.

Pancreatic cancer is the leading cause of cancer-related deaths worldwide, with limited treatment options and low long-term survival rates. The complex and variable signal regulation networks are one of the important reasons why it is difficult for pancreatic cancer to develop precise targeted therapy drugs. Numerous studies have associated feedback loop regulation with the development and therapeutic response of cancers including pancreatic cancer.

Background And Aims: We sought to compare the efficacy and safety between endoscopic radiofrequency ablation (RFA) and stent placement alone in patients with unresectable extrahepatic biliary cancer (EBC).

Methods: In this randomized controlled trial, patients with locally advanced or metastatic cholangiocarcinoma (CCA) or ampullary cancer who were unsuitable for surgery were recruited from 3 tertiary centers. Eligible patients were randomly assigned to RFA plus plastic stent placement (RFA group) or plastic stent placement alone (stent placement alone group) in a 1:1 ratio.

Heterotopic pancreas (HP) is a relatively uncommon entity that is defined as pancreatic tissue without a true anatomical or vascular connection to the pancreas. HP does not cause symptoms in most cases but can occasionally produce various manifestations, including nausea, vomiting, abdominal pain, and even heterotopic pancreatitis. Here, we report an unusual case in which heterotopic pancreatitis complicated by the formation of a pseudocyst that caused gastric outlet obstruction was diagnosed based on serum hyperamylasemia and findings from endoscopic ultrasonography (EUS)-guided fine needle aspiration (EUS-FNA) cytology.

Backgrounds/aims: Thrombocytosis had been found to be associated with tumor metastasis and poor prognosis in malignant tumors including colorectal cancer (CRC). In the present study, we investigated the relationship between the platelet and the biological features in patients with CRC in China.

Methodology: The correlation of platelet counts of 150 cases with CRC with their clinicopathological characteristics was explored.
