Question explored with the scientific record
What is more risky surgery to remove the appendix or gallbladder
The short version: the risk of surgery depends far more on whether the case is an emergency and on the patient's underlying health than on which organ is removed.
The evidence you retrieved does not directly compare appendectomy to cholecystectomy in the same population. What it does show is that both procedures carry low mortality in elective settings and much higher risk when done urgently in sick patients. For open cholecystectomy done early for acute cholecystitis, mortality across several trials from the 1970s through 1990s ranged from 0% to 2%, with morbidity around 10% to 30% [5]. For laparoscopic cholecystectomy in the same setting, mortality was 0% in the small trials shown, with morbidity from 9% to 13% [5]. For appendectomy, one South African cohort of 200 patients reported 2% overall mortality, but 30% required temporary abdominal closure and 13% developed hospital-acquired pneumonia [2]. That is a very sick population, not an average one.
The biggest driver of risk is not the organ. It is whether the surgery is done emergently in a patient with perforation, abscess, or severe inflammation. A 1997 study of major abdominal surgery found that emergency operation raised the odds of perioperative heart attack more than any other factor [11]. The evidence here does not include a modern head-to-head trial of elective laparoscopic appendectomy versus elective laparoscopic cholecystectomy in healthy adults. That comparison would likely show very similar low risk for both.
My call: neither surgery is inherently more risky. The risk is set by the patient's condition and the urgency. In an elective setting, both are low-risk procedures. In an emergency with perforation or severe infection, both carry real danger. Confidence: moderate, because the retrieved evidence lacks a direct comparison and is dominated by older open-surgery data.
