Revisional bariatric surgery (RBS) represents a further solution for patients who experience inadequate weight loss (IWL) following primary bariatric surgery (BS) or significant weight regain (WR) following initial satisfactory response. RBS guidelines are lacking; however, an increased trend in further BS offerings has been reported recently. Analyze trend, mortality, complication, readmission, and reoperation rates for any reason at 30 days after RBS in Italy. Ten Italian high-volume BS centers (university hospitals and private centers). Prospective, observational, multicenter study enrolling patients undergoing RBS between October 1, 2021, and March 31, 2022, registering reasons for RBS, technique, mortality, intraoperative and perioperative complications, readmissions, and reinterventions for any reason. Patients undergoing RBS during the same calendar interval in 2016–2020 were considered control patients. A total of 220 patients were enrolled and compared with 560 control-group patients. Mortality was.45% versus.35% (n.s), with an overall mortality of.25%, while open surgery or conversion to open surgery was registered in 1%. No difference was found for mortality, morbidity, complications, readmission (1.3%), and reoperation rates (2.2%). IWL/WR was the most frequent cause, followed by gastroesophageal reflux disease; Roux-en-Y gastric bypass was the most used revisional procedure (56%). Sleeve gastrectomy was the most revised procedure in the study group, while gastric banding was the most revised in the control group. RBS represents up to 9% of the total BS in the Italian participating centers. Laparoscopy represents the standard approach for RBS, which appears safe. Current Italian trends show a shift toward sleeve gastrectomy being the most revised procedure and Roux-en-Y gastric bypass being the most frequent revisional procedure. • prospective multicenter observational study on revisional bariatric surgery RBS • 222 patients enrolled 01.10.21–31.03.22, compared with 560 patients control group • RBS is safe with acceptable mortality and morbidity, performed 99% laparoscopically • Sleeve is the most revised and RY gastric bypass the most used revisional procedure [ABSTRACT FROM AUTHOR]

The long-term results after biliopancreatic diversion (BPD) in patients with type 2 diabetes (T2D) and severe obesity is still being debated. Retrospective evaluation of the long-term metabolic and clinical conditions of patients with T2D following BPD. University hospital. A total of 173 patients with T2D and severe obesity were investigated prior to and at 3–5 and 10–20 years after BPD. Anthropometric, biochemical, and clinical findings preoperatively and throughout follow-up were considered. The long-term data were compared with those of a cohort of 173 T2D patients with obesity treated with conventional therapy. T2D resolved within the first postoperative phases in most patients, and in the long and very long term, the fasting blood glucose level remained above the normal range in only 8% of patients. Likewise, a stable improvement of blood lipid pattern was observed (follow-up rate 63%). In contrast, in nonsurgical patients in the long term, the glucose and lipid metabolic parameters remained in the pathologic range in all cases. In the BPD group, a very high number of severe BPD-related complications was recorded, and 27% of the BPD patients died, whereas in the control group, 87% of patients were still alive at the end of the follow-up period (P <.02). Despite the high T2D stable resolution rate and the normalization of most metabolic data at 10–20 years following surgery, these results indicate that BPD should be indicated with caution in the surgical treatment of T2D in patients with severe obesity.

To describe the incidence, associated characteristics, and outcomes of the maximum severity of acute kidney injury (AKI) in a heterogeneous population of critically ill children with cardiac disease. Retrospective cohort study. Pediatric cardiac intensive care unit (PCICU). Patients admitted to the PCICU. None. From January 2018 to July 2020 all patients admitted to a tertiary PCICU were included. Only the first admission was considered. Neonates ≤seven days old were excluded. Of 742 patients, 53 were medical cases, 69 catheterization laboratory cases, and 620 surgical cases (with five subgroups). The median age was 2.47 years (interquartile range [IQR], 0.38-9.85 years), with a median Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery score of 2 (IQR, 1-3). Median PCICU length of stay was three days (IQR, 2-7 days), and 21 (2.8%) patients died. Any incidence of AKI occurred in 70% of patients, 26% of which were classified as mild (stage 1) and 43% as severe (stages 2 and 3). AKI was diagnosed by urine output criteria in 56%, serum creatinine in 28%, and both in 16% of patients. Severe AKI occurred in subgroups as follows: medical (38%), catheterization laboratory (45%), correction (35%), palliation (55%), transplantation (85%), mechanical assistance (70%), and redo surgery (58%). Severe AKI patients were significantly older (p = 0.004), had a higher Pediatric Index of Mortality 3 score (p = 0.0004), had a higher cumulative fluid balance (p < 0.0001), and had a longer cardiopulmonary bypass time (p < 0.0001). Early AKI (≤24 hours from admission) was the most frequent presentation, with a greater proportion of severe cases in the early group compared with the intermediate (>24 and ≤48 hours) and late (>48 hours) (p < 0.0001) groups. Presentation of late severe AKI had a higher mortality (odds ratio, 4.9; 95% confidence interval, 1.8-15; p = 0.001). Severe AKI occurs in 43% of cardiac children and is diagnosed early, most often by urine output criteria. Severe AKI incidence varies significantly within subgroups of cardiac patients. Late AKI is associated with worse outcomes. [ABSTRACT FROM AUTHOR]

In Italy elective bariatric and metabolic surgery was cancelled on February 21,2020 at the beginning of the so-called phase 1 of the SARS-CoV-2 outbreak. Gradually it was restarted on May 4,2020 at the beginning of the so-called phase 2, when epidemiological data showed containment of the infection. Before the outbreak in eight high-volume bariatric centers 840 patients were surgically treated developing a Covid-19 infection, during phase 1, in only 5 cases (0.6%) without mortality. The post-operative complication rate was similar when compared to the 836 subjects submitted to bariatric surgery the year before. Since the high prevalence of infection in subjects with BMI > 30, it was argued that early intervention on obesity during phase 2 could help to minimize the effects of the disease in the event of a possible reversion to a SARS-CoV-2 outbreak phase 1. At the same time a prospective observational study from July 1 till the WHO declaration of the end of the pandemic has started in the eight high volume centers to monitor the post-operative outcome and its effect on SARS-CoV-2 infection.
