Anastomotic stricture with the EEA-Stapler after colorectal anastomosis.

OBJECTIVE

Analysis of colorectal anastomosis stricture incidence after anterior resection of the rectum performed with the EEA-Stapler. To find out if differences existed in stricture incidence considering factors such, as age, neoplasia, postoperative radiotherapy, tumor stage and anastomic level.

DESIGN

Longitudinal descriptive study.

PATIENTS AND METHOD

67 patients who underwent rectal anterior resection using the EEA-Stapler were evaluated. Data from sex, age, indication for operation, postoperative radiotherapy, tumor staging and anastomic level were recorded and compared with presence of stricture anastomosis. Stenosis was evaluated and graded as follows: grade O, no stenosis; grade I, no symptoms, X-ray or endoscopic finding; grade II, symptoms, the patients require ballon catheter dilation; and grade III, invalidant symptoms, the patients require surgery.

RESULTS

Twelve patients (20%) were recorded as grade II and 3 patients (5%) as grade III. There were no statistically significant differences between prevalence of stricture and sex, age, neoplasic or non-neoplasic conditions, previous radiotherapy, level of anastomosis, and tumor stage.

CONCLUSION

Stenosis after colorectal anastomosis with stapler devices must not be considered as an uncommon complication. In 20% of patients it may be a serious state that may require repeated catheter balloon dilations or surgery. Such condition is not dependent on diverse factors studied.
