Abstract
INTRODUCTION: Mini-gastric bypass (MGB) is a bariatric surgical technique popular in many centers due to shorter duration, easier technique, and excellent weight loss results. However, it may be associated with postoperative malnutrition. This case describes the clinical course and unfortunate outcome of a morbidly obese patient who underwent MGB and developed malnutrition in the first postoperative year.
PRESENTATION OF CASE: A 37 year-old female patient with a BMI of 44kg/m(2) successfully underwent MGB surgery in June 2015 and was discharged uneventfully. She presented with lower extremity edema and generalized weakness 8 months later, with a blood albumin level of 3.1g/dL, compared to a normal preoperative value. She was admitted and received a high-protein diet, and her clinical condition improved. Three months after her discharge, she was readmitted with the same complaints, as well as pancytopenia. She was also hypocupremic. After unsuccessful intensive supportive measures, she finally underwent revisional gastrogastrostomy. However, she developed signs and symptoms of profound liver failure postoperatively (albumin 1.8g/dL; total bilirubin 7.5mg/dL; prothrombin time 34s) and pancytopenia persisted. All resuscitative measures were unsuccessful and she expired in July 2016.
DISCUSSION: Multiple factors can contribute to postoperative malnutrition and liver dysfunction after MGB, including the presence of baseline liver disease, inadequate diet supplementation, leaving a too-short common small intestinal channel, and ethnic variations in small bowel length. These factors should also be considered when deciding to perform corrective surgery.
CONCLUSION: Careful, individualized treatment and follow-up plans may help to prevent such catastrophic consequences.
