Regular surveillance visits and assessments are crucial in cancer care to detect any recurrence or new tumors early. Similarly, in bariatric surgery, postoperative monitoring of weight loss, nutritional status, comorbidities, and psychological health can help identify potential complications, ensure patient compliance, and provide necessary interventions promptly.

By embracing the principles of the oncology model, bariatric surgery can evolve into a more personalized and patient-centered approach, leading to enhanced outcomes and improved quality of life for individuals with obesity.

Personalized Approach in Bariatric Surgery

A key aspect of the oncology model in obesity treatment is the adoption of a personalized approach in bariatric surgery.

Recognizing that obesity is a multifactorial condition with individual variations, tailoring the treatment plan to the specific needs and characteristics of each patient is crucial for optimizing outcomes.

The choice of the most suitable bariatric surgery procedure for an individual should consider several factors. Patient-related factors such as age, body mass index, presence of comorbidities, metabolic profile, and psychological well-being play a role in determining the appropriate surgical intervention.

For instance, individuals with uncontrolled type 2 diabetes may benefit more from metabolic procedures like gastric bypass, which has shown superior glycemic control compared to other procedures. In addition, the patient's preferences, expectations, and lifestyle factors should be considered to ensure treatment adherence and long-term success.

Understanding the patient's motivations, beliefs, and concerns can guide the selection of the most appropriate surgical option and facilitate shared decision-making between the healthcare team and the patient. Furthermore, preoperative evaluation is crucial in the personalized approach to bariatric surgery. Comprehensive assessments, including medical history, physical examination, nutritional evaluation, and psychological assessment, help identify potential risks and tailor the preoperative management plan accordingly.
