Hemorrhagic and Thromboembolic Complications after Bariatric Surgery in Patients Receiving Chronic Anticoagulation Therapy

Obesity Surgery volume 18, pages 167–170 (2008)Cite this article

Abstract

Background

Perioperative management of bariatric surgical patients receiving chronic anticoagulation requires an understanding of potential hemorrhagic and thromboembolic risks. The aim of this study is to evaluate hemorrhagic and thromboembolic complications in morbidly obese patients who are on oral anticoagulation treatment and subsequently undergo laparoscopic bariatric surgery.

Methods

The medical records of all laparoscopic Roux-en-Y gastric bypass (LRYGB) patients from June 2001 to March 2006 were retrospectively reviewed. In addition, data of patients who received chronic anticoagulation therapy with Coumadin and underwent laparoscopic Roux-en-Y gastric bypass was analyzed. Clinical parameters included length of hospitalization, hemorrhagic complications, thromboembolic complications, conversion rate, reoperation, and blood transfusion.

Results

During the study period, 1,700 consecutive patients underwent bariatric surgery for the treatment of morbid obesity. Of these, 21 patients were treated with chronic oral anticoagulation; 3 of the 21 (14%) had hemorrhagic complications: one patient had intraluminal hemorrhage and two patients had intraabdominal hemorrhage. Two patients required blood transfusion, and one patient underwent surgical reintervention. None of the 21 laparoscopic operations were converted to open procedures. There were no postoperative mortalities, and there were no thromboembolic events in this series.

Conclusions

Laparoscopic bariatric surgery can be performed relatively safely in morbidly obese patients who are treated with chronic oral anticoagulation. Even in the presence of bleeding, patients can be successfully treated without the need for reoperation.
