“…During the postoperative period, if there is a clinical suspicion of complications, radiological examinations are carried out: UGI series, CT and magnetic resonance imaging (MRI). The clinical suspicion of possible complications is the onset of abdominal or chest pain, tachycardia, tachypnoea, dyspnoea, hypotension, hematemesis/melena and vomiting, fever and laboratory sign of infectious or inflammatory status such as leucocytosis and increased in PCR and VES values [ 9 ].…”

Obesity is a widespread pathology among the population related to an increase in mortality and morbidity of patients. Bariatric surgery provides several forms of treatment for obese patients. Laparoscopic mini/one anastomosis gastric bypass (MGB/OAGB) is a recent low risk bariatric surgical procedure common in a large number of countries in the treatment of severe obesity. MGB/OAGB, compared to other bariatric surgery techniques, offers the significant technical improvement of requiring only one anastomosis in place of two. In this scenario, diagnostic imaging takes a significant role in the postoperative period, to evaluate the outcomes of surgical treatment and to detect possible complications both in early and late postoperative period. The prevalent radiological procedure to investigate suspicions of clinical post-operative complications is Computed tomography (CT) with oral and intravenous contrast administration. This pictorial essay aims to illustrate and identify normal radiological aspects of MGB/OAGB and post-surgery complication imaging features. We think that this article will serve to familiarize all the specialists with the diagnostic imaging of MGB/OAGB.

“…Pneumonitis and pulmonary embolism are rare pulmonary complications after MGB/OAGB because of the short low-risk operation and thanks to the use of antithrombotic and antibiotic prophylaxis. As a consequence of bariatric surgery, a slight pleural effusion is a common occurrence, in particular on the left side [ 9 ].…”

“…Later, an antireflux stitch is made to prevent bile reflux in the bypassed segment with an anchoring suture adjacent to the gastrojejunostomy. Normally, surgeons do not close the Petersen's space and the procedure is concluded with a leak test using an intraoperative EGD [45][46][47][48][49] (►Fig. 2).…”

“…28 Once the complication is diagnosed, an aggressive management should be considered to prevent prolonged hospital stay and avoid further interventions. 48,61 Postoperative bleeding occurs in less than 3% of the cases, and the management tends to be conservative and rarely require additional surgical interventions. 38,62,63 Similarly, in a retrospective cohort study performed on 653 patients undergoing OAGB, the postoperative bleeding rate was 1.3%.…”

The most effective long-term treatment for severe obesity is bariatric surgery with improvement or resolution of obesity-related comorbidities. Single-anastomosis procedures including single-anastomosis duodenoileal bypass and one-anastomosis gastric bypass are relatively new procedures that are gaining popularity worldwide. These surgical techniques are perceived to be less complex with a shorter learning curve in comparison to the standard biliopancreatic diversion with duodenal switch and Roux-en-Y gastric bypass; however, long-term outcomes and complications remain controversial. This article aims to review one-anastomosis procedures, evaluate their outcomes, and review potential complications.
