A. Pessina et al., Adaptability and compliance of the obese patient to restrictive gastric surgery in the short term, OBES SURG, 11(4), 2001, pp. 459-463
Background: Low compliance, as well as recurrent vomiting, are often pointe
d out as the main causes of both postoperative technical complications and
poor weight loss.
Methods: 50 patients were examined. All underwent preoperative psychologica
l assessment through an intensive clinical interview. Between October 1999
and January 2000, all the patients underwent vertical banded gastroplasty (
VBG). Excess Weight Loss (EWL) was followed, and the number of vomiting epi
sodes was recorded at 1, 3 and 6 months after surgery.
Results: 3 different groups of patients could be distinguished: 1) those wi
th no vomiting and good weight loss; 2) those with sporadic vomiting and fa
irly good weight loss; and 3) those with frequent vomiting and poorer weigh
t loss. However, this last group of patients was not homogeneous and should
be divided into 2 subgroups: 1) patients who lose weight, while vomiting;
2) patients who do not lose weight, while vomiting.
Conclusions: The experience of vomiting is a crucial cross-roads. The influ
ence of psychosocial factors was noticed in all patients. The absence of ps
ychosocial stressors, together with realistic expectations and a strong mot
ivation to change, should be considered as reliable and replicable predicto
rs of success. However, even those patients with accentuated psychological
difficulties were able to succeed in coping with them, and achieved a good
weight outcome, with good effects on the psychic side. Therefore, the evide
nce of psychological disorders cannot be taken as an absolute criterion of
selection/exclusion of candidates for the operation. Accurate presurgical e
ducation and postoperative psychological support are likely to increase the
patient's compliance and the percentage of successful cases.
