Background: Abstract
Currently, obesity rates are continuously increasing worldwide. If surgery is necessary, it
will be challenging due to the increased thickness of the abdominal wall. Thickness of the
abdominal wall indicates the difficulty level of procedure and length of the instruments
used such as Trocar or Veress needle for insufflation. Anthropometric measurement may
help estimate the thickness of the abdominal wall and can be done easily without requiring
expensive equipment. This study aims to investigate anthropometric measurement as a
predictor of abdominal wall thickness in obese. By recording abdominal wall thickening at
a total of 9 points, which are commonly used as landmarks in surgery.
Methods: Cross-sectional study in single center. Patients who aged 15-80 years, with a BMI ≥ 30 kg/
m², who undergo CT whole abdomen/ KUB from any indication between September 2024
and December 2024. Clinical data included patient characteristic, BMI, Neck circumference,
Mid-arm circumference, Waist circumference and abdominal wall thickness from CT
abdomen/KUB was recorded ,9 point on the abdominal wall. Correlation between
anthropometric measurement and abdominal wall thickness was analyzed.
Results: Among 105 obese participants underwent CT abdomen/KUB. Mean age was 55 ± 13.7 years.
Male was 49.5% and mean BMI was 33.5 ± 3.4 kg/m2. By calculating correlation coefficient,
the positive strong correlation between BMI and abdominal wall thickness 6/9 points [RUQ
(rs 0.55, p<0.001,), LUQ (rs 0.45, p<0.001), RMQ (rs 0.41, p<0.001), RLQ (rs 0.51,p<0.001),
SPB (rs 0.41, p<0.001), LLQ (rs 0.47,p <0.001)]. Followed by arm circumference and
waist circumference found strong correlation with abdominal wall thickness 3/9 points on
abdominal wall. The data was created chart to represent body parameters to abdominal
wall thickness.
Conclusion: The knowledge of the relationship between anthropometric measurements and abdominal
wall thickness, especially BMI, is valuable as it is practical, easy to use, and convenient. It
aids in preoperative planning, helps reduce complications, and improves outcomes.
