Massive obesity is prevalent and associated with serious comorbidities
. For patients who cannot sustain weight loss, malabsorption and gastr
ic reduction operations have been developed. Patients with the former
operation require surveillance for protein malnutrition and other sequ
elae; those with gastric reduction require a permanent tiny reservoir
and stoma. Long-term follow-up surveillance is necessary. Postoperativ
ely, 15% to 40% of patients, depending on the operative procedure perf
ormed, fail to maintain adequate weight loss. Successful weight loss i
n most of these patients makes this challenging surgery worthwhile, wi
th alleviation of devastating disease and marked improvement in qualit
y of life.
