Early Postoperative Complications in Patients Undergoing Bariatric Surgery

This study, conducted in specialised high-volume bariatric surgery centres in Tijuana, Baja California, Mexico, aimed to analyze the outcomes of various bariatric surgery procedures. It include patients who underwent surgeries like sleeve gastrectomy, gastric bypass, and others. The surgeries were performed by five specialized surgeons with assistance from ten bariatric surgery subspecialists. The researchers reviewed electronic medical records and excluded patients with incomplete information. Postoperative complications requiring additional medical or surgical interventions were noted. Statistical analysis was conducted using SPSS software, focusing on descriptive measures like frequencies, percentages, means, and standard deviations.

• Sleeve gastrectomy, Roux-en-Y gastric bypass, mini-gastric bypass, SADIS, intragastric balloon insertion, and gastric band placement are bariatric surgeries. (Procedure): Sleeve gastrectomy: reduces stomach size. Roux-en-Y gastric bypass: limits calorie absorption. Mini gastric bypass: achieves weight loss with fewer incisions. SADIS: combines sleeve gastrectomy with small bowel bypass. Intragastric balloon: reduces stomach volume. Gastric banding: restricts food intake.

Primary outcomes

• Rate of Postoperative Complications [30 days]: Within 30 days following surgery, the incidence of anastomotic leaks and surgical site bleeding is the main safety consequence. This outcome measure is essential for proving the safety and enhanced recovery profile, since the technique emphasizes rigorous hemostasis and anastomotic integrity-achieved through reinforced suturing and patency verification using methylene blue tests.

Secondary outcomes

• Long-term Weight Loss Efficacy [12 months]: : The percentage of excess weight loss (%EWL) at 12 months after surgery is the main indicator of efficacy. One of the main objectives of bariatric surgery is to achieve significant and long-lasting weight loss. The percentage EWL is calculated using the patient's weight reduction from pre-surgery to a year after surgery, normalized to their excess weight using optimum body weight guidelines.
