RODRIGUEZ C., Tomás et al. Predictive value of sarcopenia for anastomotic dehiscense in colon cancer surgery. Rev. cir. [online]. 2019, vol.71, n.6, pp.512-517. ISSN 2452-4557.


An important complication of colorectal surgery is anastomotic dehiscence (AD). Nutritional status is one of the important factors in AD. An objective way to evaluate the patients’ nutritional status is to measure sarcopenia, which is the reduction of skeletal muscle mass. It is possible to standardize Sarcopenia using the analysis of the Hounsfield Units (HU) and the muscular area (MA) which consider Computed Tomography of Abdomen and Pelvis (CTAP).


To evaluate whether there is a relationship between AD and the presence of sarcopenia detected by the measurement of HU and MA using CTAP. The situation considers patients undergoing colectomy for cancer.

Materials and Method:

Cases and controls were studied with analytical statistics. 21 patients with AD and 40 without AD were chosen randomly. They include > 18 years, with colectomy for cancer and primary anastomosis. Ostomized patients, who previous the surgery do not have CTAP or if it was not available to measure HU and MA, were excluded. The imaging evaluation was performed by an expert radiologist.


The comparison between groups shows that they are homogeneous with respect the sex (predominant men), age (average 60 years) and location. There are signs of imaging which suggest the presence of sarcopenia in the AD group. This is explained because there is an important statistical decrease in the HU values and a tendency to present lower MA values.


The presence of sarcopenia due to alteration of HU in a radiological study is correlated with AD, and could be a predictor of risk. The importance of this finding is that this risk factor is potentially correctable.
