A laparoscopic abdominoperineal resection is an operation in which the anus, rectum, and sigmoid colon are expelled. It is utilized to treat malignancy (cancer) found low in the rectum or in the anus, near the sphincter (muscles that control solid discharges).
Once the anus and rectum have been expelled, another opening through which waste can go from the body should be made. This opening, called a “stoma,” is produced using the digestive organ to the surface of the skin of the guts and can gauge from 1 to 1/2 inches around.
Not at all like your anus, the stoma has no sphincter muscles, so you as a rule can’t control the way out of waste. You will for the most part need to wear a pocket at all times to gather the waste stream.
What happens during a laparoscopic abdominoperineal resection?
Laparoscopy empowers the specialist to finish the surgery through little “keyhole” entry points in the belly. A laparoscope, a little, telescope-like instrument, is put through a cut close to the bellybutton.
An abdominoperineal resection is finished in 4 principle steps. These strides are portrayed underneath.
Step 1: positioning the laparoscope
When you are sleeping, the specialist will make a little cut (around 1/2 inch) close to the bellybutton. A laparoscope will be embedded into the mid-region through this entry point. Pictures taken by the laparoscope will be anticipated onto video screens put close to the working table.
Once the laparoscope is set up, the specialist will make 4 or 5 more “keyhole” entry points in the stomach area. Surgical instruments will be set through these entry points to finish the surgery.
Step 2: preparing the sigmoid colon and rectum for removal
Your specialist will finish a few stages before expelling the anus, rectum, and sigmoid colon. In the first place, the principle veins that serve the ailing segments of the entrail will be painstakingly cut and shut. Next, the specialist will free the sigmoid colon from its supporting structures and partition it from the staying digestive organ. The rectum will likewise be liberated from its encompassing structures.
Step 3: preparing the anus for removal
Once the sigmoid colon and rectum have been set up for evacuation, one of the specialists will work on the range between the legs (perineal area). This operation will permit the specialist to evacuate the butt, rectum, and sigmoid colon.
Step 4: making the stoma
Once the anus, rectum, and sigmoid colon have been evacuated, the specialist will make the stoma from one of the current entry point locales. The stoma is typically set on the left half of the mid-region.
Initial, a little plate of skin will be expelled from the entry point site. The open end of the diving colon will be pulled through this site to the surface of the skin. (this sort of stoma is called an “end colostomy”) the stoma will be sewed set up. The stomach depression will be washed out and a little waste tube will be embedded into one of the lower stomach entry point destinations. This seepage tube will advance recuperating of the tissue inside your belly. At last, your specialist will painstakingly examine the stomach cavity and join the entry points shut.
