The Auxologico Research Hospital in Milan has extensive and long-standing experience in the treatment of obesity, morbid obesity and related complications, with some of its surgeons being pioneers in this type of surgery.

The Capitanio Hospital’s General Surgery Operative Unit houses the Center for Bariatric Surgery, which focuses on diagnosing, performing surgery, and providing postoperative care.

In welcoming the patient, a team of doctors, including surgeons, hormone specialists, nutritionists and psychologists, assess her/his suitability for surgery and monitor the progress afterwards.  They use their expertise to personalize the surgery, taking into account the patient’s clinical and nutritional needs, as well as their mental state.

Personalized treatment is the real key to effective weight management and to achieving long-lasting results, as per a recent study in The European Journal of Obesity. This treatment must involve psychological monitoring by specialized professionals experienced in the field. It’s worth noting that the patient’s personal commitment is vital to the success of the treatment. The study was carried out with the cooperation of the Experimental Psychological Research Lab, the Experimental Nutrition and Obesity Research Lab, and the General Surgery Operating Unit at Auxologico.

Bariatric surgery is the only proven treatment for severe obesity (BMI > 35 and comorbidities or BMI > 40) to achieve significant and lasting weight loss.  It’s recommended when diet and behavioral changes and/or medication have not led to satisfactory results.

One of the great benefits of bariatric surgery is that it can improve or cure health issues caused by obesity such as type 2 diabetes, high blood pressure, sleep apnea, heart disease, and joint problems (conditions that often result from overexertion). These outcomes noticeably improve the patient’s mental, thinking, and interpersonal health.

But bariatric surgery may also be indicated for people who need to lose weight for orthopaedic or cardiothoracic surgery, abdominal wall reconstruction or organ transplantation.

Dr Enrico Mozzi is Head of the Bariatric Surgery Centre at Istituto Auxologico Italiano.

He has conducted over 10,000 surgeries at varying levels of complexity, either independently or as an instructor, with a primary focus on surgical procedures concerning the digestive system and wall disorders such as hernias and laparoceles.

Recently, he has concentrated on laparoscopic bariatric surgeries, which comprise the bulk of his current operations.

All procedures are performed laparoscopically and involve the reduction of stomach size. Consistent citation and clear formatting will be maintained throughout the document. This can be achieved through the partial removal of the stomach or by preventing food from passing through it. These methods reduce feelings of hunger and early satiety, resulting in weight loss and improvement or resolution of associated conditions. Abbreviations such as “BMI” and “BPD-DS” will be explained upon first use. Sentences will follow common structures, avoid jargon, and offer precise definitions where appropriate.

Thanks to the use of the latest and safest technology in our operating theatre, including 4K and 3D laparoscopic imaging systems, automatic mechanical suturing and ultrasonic dissection and coagulation devices, patients at Auxologico are able to recover faster and enjoy shorter hospital stays.
