Ultrasonography Guided Pneumoperitoneum for Laparoscopic Surgery in Morbidly Obese Patients

Brief summary (registry, in English)

Bariatric Surgery for morbid obesity is indicated when BMI \> 40 kg/m2 without comorbidities or BMI \> 35 kg/m2 with co-morbidities. Different surgeries performed for obesity are classified as restrictive, malabsorptive, and hybrid procedures. Because laparoscopic surgery has increased the interest and growth of bariatric surgery, soaring demand for laparoscopic bariatric surgery from patients has boosted the boom in bariatric surgery worldwide. Achieving pneumoperitoneum is the initial and one of the most crucial steps in any laparoscopic surgery, giving the surgeon working space to operate on a particular organ/organ system. Usually, pneumoperitoneum is achieved either by a closed technique with a veress needle or an open technique with many variations like finger assisted or the conventional open technique. Given the excess amount of subcutaneous fat in morbidly obese patients, putting a veress needle to achieve pneumoperitoneum successfully is particularly challenging which takes a toll on the operating surgeon when he/she is trying to locate the midline one can either overshoot to cause omental emphysema or undershoot getting lost in the subcutaneous fat. It is usually done in the supra umbilical area. Sometimes, due to previous surgical scars other sites are preferred. Sonography is routinely used by radiologists with negligible radiation exposure. Anesthesiologists in the operating room have used it for many assisted procedures like central line insertion / giving nerve blocks. It can also be used in obese patients undergoing metabolic surgery to assist in creating pneumoperitoneum by a veress needle. Advantages of Intraoperative ultrasonography in this particular study : 1. To quantify the thickness of subcutaneous fat 2. To visualise the linea alba and guide the veress needle safely into the peritoneal cavity 3. Real-time visualisation of the pneumoperitoneum created 4. Avoid complications like omental emphysema, bowel or vascular injury
