Final answer:
Inflammation of the membrane around the abdomen is known as peritonitis, which is a serious condition often requiring emergency surgery and antibiotics, with mortality rates between 30 to 40 percent.
Step-by-step explanation:
The inflammation of the membrane around the abdomen is known as peritonitis. This condition can develop in various scenarios, such as a breach in the wall of the alimentary canal, which allows the contents of the lumen into the peritoneal cavity. Examples include when an ulcer perforates the stomach wall or a traumatic injury occurs. Peritonitis can be a life-threatening situation that typically requires emergency surgery and intensive antibiotic therapy to treat effectively. Notably, compared to older times, the mortality rate has decreased due to advancements in medical procedures and antibiotic treatments, but it still ranges from 30 to 40 percent.
