Rumenotomy (rʊmɪnɒtəmi) is a medical term used to describe the surgical procedure of opening the rumen, a chamber in the stomach of ruminant animals. The word is derived from the Latin word "rumen" which means throat or gullet and the suffix "-otomy" which means to cut open. The spelling of this word follows standard English spelling rules with emphasis on the first syllable "ru-" pronounced with the short "u" sound and the second syllable "-men-" pronounced with the long "e" sound.
A rumenotomy is a surgical procedure that involves the surgical opening of the rumen, which is the first and largest chamber of the four-compartment stomach found in ruminant animals such as cows, sheep, and goats. This procedure is generally performed to alleviate acute or chronic conditions that affect the rumen, such as rumen impaction or ruminal bloat.
During a rumenotomy, the animal is placed under general anesthesia, and an incision is made in the left flank region to gain access to the rumen. Once the rumen is opened, its contents are carefully inspected and a thorough evaluation is done to identify any abnormalities or obstructions. These may include impacted feed material, foreign bodies, or gases causing bloat.
The surgeon then proceeds to remove or alleviate the identified issue, which may involve evacuating ruminal gases, removing blockages, or clearing impacted feed material from the rumen. After the procedure, the rumenotomy incision is closed using sutures, and the animal is closely monitored during the recovery period.
Rumenotomies are typically conducted by experienced veterinarians with expertise in large animal surgery. Although it is an invasive procedure that carries inherent risks, rumenotomies can be life-saving for ruminant animals suffering from severe rumen-related conditions that cannot be resolved through nonsurgical means.

The word "rumenotomy" is derived from two root terms: "rumen" and "otomy".
1. "Rumen" refers to the first and largest compartment of the stomach in ruminant animals (such as cows, goats, and sheep). It is responsible for the pre-processing of food through fermentation.
- The term "rumen" itself originates from Latin, where "ruminare" means "to chew the cud".
2. "-otomy" is a suffix that is used in medical terminology to denote a surgical incision or the creation of an opening.
- The suffix "-otomy" is derived from the Greek word "tomē", which means "a cutting" or "incision".
