Microbiota dynamics preceding bariatric surgery as obesity treatment: a comprehensive review. Front Nutr 2024; 11:1393182. [PMID: 38633602 PMCID: PMC11021787 DOI: 10.3389/fnut.2024.1393182] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 03/18/2024] [Indexed: 04/19/2024] Open
Abstract
The review present data on the intricate relationship between bariatric surgery, gut microbiota, and metabolic health in obesity treatment. Bariatric surgery, is recognized as an effective intervention for managing morbid obesity, including various techniques with distinct mechanisms of action, efficacy, and safety profiles including Roux-en-Y Gastric Bypass (RYGB), Sleeve Gastrectomy (SG), Laparoscopic Adjustable Gastric Banding (LAGB), and Biliopancreatic Diversion (BPD). RYGB and SG are the most prevalent procedures globally, inducing gut microbiota changes that influence microbial diversity and abundance. Post-surgery, alterations in bacterial communities occur, such as the increased of Escherichia coli inversely correlated with fat mass and leptin levels. During digestion, microbiota produce physiologically active compounds like bile acids (Bas) and short-chain fatty acids (SCFAs). SCFAs, derived by microbial fermentation, influence appetite, energy metabolism, and obesity-related pathways. Bas, altered by surgery, modulate glucose metabolism and insulin sensitivity. Furthermore, SG and RYGB enhance incretin secretion, particularly glucagon-like peptide 1 (GLP-1). Therefore, understanding microbiota changes after bariatric surgery could be crucial for predicting metabolic outcomes and developing targeted interventions for obesity management.

Abstract
PURPOSE Internal herniation (IH) is the most common complication after Roux-en-Y gastric bypass surgery (RYGB). Although primary closure has reduced the incidence, recurrences are a continued problem. This study aimed to investigate long-term follow-up and recurrence risk of IH surgery. METHODS A retrospective cohort study of laparoscopic RYGB operated patients operated for a first IH between April 2012 and April 2015 at Skåne University Hospital in Malmö, Sweden. Status of primary closure of mesenteric gaps, time since RYGB, and findings at IH surgery were retrieved from medical records. Follow-up until December 31st, 2019, included recurrences of IH, number of computed tomography (CT) scans, emergency visits, readmissions, and other acute surgeries. RESULTS IH (n = 44) occurred almost equally in Petersen's space (n = 24) and beneath the jejunojejunostomy (n = 20). Long-term follow-up (median 75 months) of 43 patients registered an IH recurrence rate of 14% (n = 6). All recurrences occurred in the other mesenteric gap. One patient suffered a third IH, and one patient had four IH events. During follow-up, 56% (n = 24) had ER visits for abdominal pain, 47% (n = 20) had ≥ 1 abdominal CT scan, and 40% (n = 17) were readmitted. A third of readmitted (6/17) patients suffered a recurrence of internal herniation. Two other patients were readmitted ≥ 10 times for chronic abdominal pain. CONCLUSION Surgery for IH had a low risk of recurrence at the treated mesenteric gap, but a 14% recurrence risk at the other mesenteric gap, emphasizing the importance of carefully investigating weaknesses or gaps at the other mesenteric defect during surgery for IH.

The Diagnostic Accuracy of Abdominal Computed Tomography in Diagnosing Internal Herniation Following Roux-en-Y Gastric Bypass Surgery: A Systematic Review and Meta-analysis. Ann Surg 2022; 275:856-863. [PMID: 35129527 DOI: 10.1097/sla.0000000000005247] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To analyze the diagnostic accuracy of abdominal computed tomography (CT) in diagnosing internal herniation (IH) following Rouxen-Y gastric bypass (RYGB) surgery. SUMMARY OF BACKGROUND DATA IH is one of the most important and challenging complications following RYGB. Therefore, early and adequate diagnosis of IH is necessary. Currently, exploratory surgery is considered the gold standard in diagnosing IH. Although CT scans are frequently being used, the true diagnostic accuracy in diagnosing IH remains unclear. METHODS PubMed, Embase, and Cochrane databases were systematically searched for relevant articles describing the diagnostic accuracy of abdominal CT in diagnosing IH after RYGB. Data were extracted, recalculated, and pooled to report on the overall diagnostic accuracy of CT in diagnosing IH, and the diagnostic accuracy of specific radiological signs. RESULTS A total of 20 studies describing 1637 patients were included. seventeen studies provided data regarding the overall diagnostic accuracy: pooled sensitivity of 82.0%, specificity of 84.8%, positive predictive value of 82.7%, and negative predictive value of 85.8% were calculated. Eleven studies reported on specific CT signs and their diagnostic accuracy. The radiological signs with the highest sensitivity were the signs of venous congestion, swirl, and mesenteric oedema (sensitivity of 78.7%, 77.8%, and 67.2%, respectively). CONCLUSIONS This meta-analysis demonstrates that CT is a reliable imaging modality for the detection of IH. Therefore, abdominal CT imaging should be added to the diagnostic work-up for RYGB patients who present themselves with abdominal pain suggestive of IH to improve patient selection for explorative surgery.

Abstract
BACKGROUND Internal herniation (IH) is a well-known complication after laparoscopic gastric bypass (LGB). Diagnosing and managing IH can be challenging. This retrospective cohort study aimed to achieve a greater understanding of symptomatology, diagnostic tools, complications, risk of IH recurrence, and symptom relief in IH patients. METHODS We included patients who underwent LGB surgery at our institution between 2011 and 2015. Mesenteric defects were not preventively closed during LGB. We focused on LGB patients who underwent surgical intervention(s) for suspected IH during a 7-year study period. We studied patient characteristics, (predictive) symptoms and signs, abdominal imaging, operative findings, post-operative course, and risk of (recurrent) IH. RESULTS A total of 1588 patients were included. In total, 243 patients underwent IH-related diagnostic laparoscopy. Radiating pain to the back (OR 2.45, p = .03), post-prandial pain (OR 3.23, p = .00), and leukocytosis (OR 15.53, p = .01) were identified as predictors of IH. The estimated risk of IH-related diagnostic laparoscopy was 16% at 3 years post-LGB, and the risk of confirmed IH was 12%. The estimated risk of diagnostic laparoscopy for suspected recurrent IH was 10% at 5 years post-LGB. In patients who underwent secondary mesenteric defects closure, post-operative symptom relief was reported in 84%. CONCLUSION This study demonstrates a considerable risk of developing IH after LGB without preventive closure of the mesenteric defects. We emphasize the value of diagnostic laparoscopy to achieve symptom relief in patients with suspicion of IH. Preoperative diagnosis of IH can be improved by being watchful of specific symptoms and signs which can predict the intra-operative presence of IH.

Abstract
PURPOSE The clinical diagnosis of an internal herniation (IH) after a Roux-en-Y Gastric Bypass (RYGB) remains difficult; therefore, performing a CT scan is usually part of the diagnostic process. The goal of this study was to assess the incidence of IH in patients with open and closed MD (mesenteric defect) and to study if the ability to diagnose an IH with a CT scan is different between these groups. MATERIALS AND METHODS IH was defined as a visible intestine through the mesenteric defect underneath the jejunojejunostomy and/or in the Petersen's space. CT scan outcomes were compared with the clinical diagnosis of an IH. Until 31 June 2013, standard care was to leave mesenteric defects (MDs) open; after this date, they were always closed. RESULTS The incidence of IH in the primarily non-closed group was 3.9%, and in the primarily closed group, this was 1.3% (p = 0.001). In group A (non-closed MD and CT), the sensitivity of the CT scan was 80%, and specificity was 0%. In group C (closed MD and CT), the sensitivity was 64.7%, and specificity was 89.5%. In group B (non-closed, no CT), an IH was visible in 58.7% of the cases and not in 41.3%. In group D (only a re-laparoscopy), an IH was visible in 34.3% of the cases and not in 65.7%. CONCLUSIONS Using the CT scan in suspected IH is not useful in if the MDs were not closed. If the MDs were closed, then a CT scan is predictive for the diagnosis IH.
