Laparoscopic One Anastomosis Gastric Bypass (OAGB) Mini Gastric Bypass (MGB) Early (≤30 Days) Complications – Diagnosis and Management

One anastomosis gastric bypass (OAGB)/ mini gastric bypass (MGB) is now a recognized mainstream bariatric procedure being adopted by an increasing number of surgeons. Though OAGB-MGB has a lower complication rate, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. The incidence of early complications was mostly clinical, based on the presence of signs and symptoms such as pain, vomiting, bleeding, fever, tachycardia, and tachypnea. Early recognition of complications would help in achieving favorable outcomes. The incidence of early complications was low. We evaluate the experience and early postoperative follow-up in a large cohort of patients in whom laparoscopic OAGB-MGB was performed at a single institution. In this chapter, we discuss how to prevent and manage its specific complications.
