The placement of a colon stent involves endoscopic techniques similar to esophageal stenting. A thin tube called an endoscope is inserted into the rectum and guided through the colon to locate the blockage. Using fluoroscopy or endoscopic guidance, a guidewire is passed through the narrowed area and then removed after positioning it properly.
The pseudocyst is identified and accessed using laparoscopic techniques. Once the pseudocyst cavity is located, it is entered and aspirated, and an opening is created into the stomach for drainage. Laparoscopic drainage may result in better cosmetic appearance and decreased pain following surgery. [8]
