Early Postoperative Complications in Patients Undergoing Bariatric Surgery

April 15, 2024 updated by: GONZALEZ-OJEDA ALEJANDRO, Instituto Mexicano del Seguro Social

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

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

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Patients undergoing bariatric surgery
Procedure: Sleeve gastrectomy, Roux-en-Y gastric bypass, mini-gastric bypass, SADIS, intragastric balloon insertion, and gastric band placement are bariatric surgeries.
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

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
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.
