Characteristics of morbid obese patients with high-risk cardiac disease undergoing laparoscopic sleeve gastrectomy surgery

Introduction: Bariatric surgery is an efficient and safe method of weight reduction among patients who have morbid obesity which cannot be treated by the conservative approach. Safety and feasibility of bariatric surgery among high-risk patients are understudied. Therefore, we aimed to report the patient-level characteristics and outcome among high-risk obese patients undergoing laparoscopic sleeve gastrectomy surgery in Saudi Arabia. Methods: A retrospective analysis was performed among 13 morbidly obese (BMI >39 kg/m2) patients with high-risk cardiac disease, who were referred to Upper Gastro-Intestinal Surgery Clinic at King Khalid University Hospital, which is a center of excellence in bariatric surgery, for consideration for weight loss surgery. Retrospective data on preoperative weight, height, and BMI, operative details, perioperative complications, length of stay, and information on comorbidities and endocrinal disease were collected for analysis and reporting. Results: A total of 13 patients were included in the analysis. Of the total, 61.5% were males with a mean age 40.38 (SD: 16.28) and a mean BMI 51.87 (SD: 7.69). The mean duration of surgery was 33.30 min (SD: 31.01), while the mean duration of anesthesia was 83.61 min (SD: 34.73). The mean length of stay was 6.76 days (SD: 3.89). Three patients required postoperative HDU admission with a mean length of stay of 1 day, while 5 patients required postoperative ICU admission with a length of stay ranging from 1 to 3 days. Within 30 days after discharge, only 1 patient required ER visit and none of the patients reported any postoperative morbidity and mortality. Conclusion: Through this study, we can conclude that laparoscopic sleeve gastrectomy surgery can be considered a safe procedure. However, further studies with a large sample size and a more robust methodology are needed to build upon the findings of this study.
