Abstract

Insights

Endoscopic mucosal resection with suction is more effective than endoscopic submucosal dissection for small rectal neuroendocrine tumors (NETs). This method offers a higher complete resection rate and shorter procedure time with similar safety outcomes.

Area of Science:

  • Gastroenterology
  • Surgical Oncology
  • Endoscopic Surgery

Background:

  • Small rectal neuroendocrine tumors (NETs) lack established optimal treatment guidelines.
  • Endoscopic mucosal resection (EMR) with suction and endoscopic submucosal dissection (ESD) are potential treatments.

Purpose of the Study:

  • To compare the efficacy and safety of EMR with suction versus ESD for small rectal NETs.
  • To evaluate complete resection rates, complication rates, procedure times, and recurrence rates.

Main Methods:

  • A meta-analysis of 14 studies involving 823 patients.
  • Literature search conducted using PubMed and Embase databases.
  • Primary outcome: complete resection rate; Secondary outcomes: complication, procedure time, and recurrence rates.

Main Results:

  • EMR with suction achieved a higher complete resection rate (93.65%) compared to ESD (84.08%).
  • EMR with suction demonstrated significantly shorter procedure times.
  • No significant differences were observed in overall complication or recurrence rates between the two methods.

Conclusions:

  • EMR with suction is superior to ESD for treating small rectal NETs (≤10 mm).
  • EMR with suction offers higher complete resection rates and shorter procedure times.
  • Both methods show similar safety profiles regarding complications and recurrence.

Endoscopic Studies II: Thoracocentesis

Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures II: Colonoscopy

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
