Incidence of Early Postoperative Complications in Patients Undergoing Bariatric Surgery in 2022 Tijuana, Baja California

This study examined immediate postoperative complications in patients undergoing various bariatric surgeries, aiming to evaluate the safety and efficacy of these interventions. Conducted at specialized high-volume bariatric surgery centers in Tijuana, Mexico. Predominantly female patients with severe obesity underwent procedures like sleeve gastrectomy and Roux-en-Y gastric bypass. Immediate complications were rare, occurring in only 0.38% of patients, with bleeding being the most common issue. Surgical reintervention within 48 hours was required in 0.33% of cases. The study's low complication rate suggests that surgeon expertise is crucial in minimizing risks and improving postoperative outcomes in bariatric surgery.

Study Overview

Detailed Description

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.

Study Population

This study included patients aged 18 and above with varying degrees of overweight or obesity who underwent bariatric surgery at specialized centers in Tijuana, Mexico. The surgeries examined were sleeve gastrectomy, Roux-en-Y gastric bypass, mini-gastric bypass, SADIS, intragastric balloon insertion, and gastric band placement. These procedures were performed by five bariatric surgery specialists with assistance from ten certified subspecialists. Patients with incomplete medical records were excluded. Immediate postoperative complications were defined as events requiring additional medical or surgical interventions beyond routine care.

Description

Inclusion Criteria:

  • Patients aged 18 years and above
  • Varying degrees of overweight or obesity who underwent surgery at the participating hospitals

Exclusion Criteria:

  • incomplete or insufficient information in their medical records

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Patients undergoing bariatric surgery
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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Rate of Postoperative Complications
Time Frame: 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.
30 days

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Long-term Weight Loss Efficacy
Time Frame: 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.
