RESUMO
Obesity prevalence is increasing with the modern lifestyle. Bariatric surgery is an excellent method to sustain weight reduction and the most commonly performed surgery is laparoscopic sleeve gastrectomy (LSG). The laparoscopic approach can be challenged in certain conditions such as situs inversus totalis (SIT). We report a 38-year-old gentleman with class II obesity known to have SIT. After complete preoperative preparation, we performed LSG with no complications. The main difficulty of performing any surgical procedure for SIT patients is the reversed anatomy. It is essential to highlight the importance of anatomy for surgeons. Proper preoperative anatomy assessment along with the surgeon's experience is the key element to perform LSG or any bariatric laparoscopic procedure in rare conditions such as SIT.
