This systematic review aims to evaluate the current evidence regarding safety and efficacy of magnetic sphincter augmentation (MSA) for the treatment of gastroesophageal reflux disease (GERD) after laparoscopic sleeve gastrectomy (LSG). Conversion to Roux-en-Y gastric bypass (RYGB) carries the risk of surgical and metabolic complications and may be contraindicated in patients with normalized or near-normalized body mass index. The LINX™ procedure aims to restore LES competency and to repair the crura. We included 109 patients (14 studies) undergoing LINX™ implant after LSG. Median follow-up was 18.9 months (range 0.3-63). Both the GERD-HRQL (38 ± 13 vs. 10 ± 11; p = 0.0078) and daily PPI use (97.4% vs. 25.3%; p < 0.0001) were significantly improved. Overall, 31.8% of the patients experienced device-related adverse events, mainly self-limiting. LINX™ explant for esophageal erosion occurred in 0.9% of the patients.

Obesity, type 2 diabetes (T2D), and chronic kidney disease (CKD) are thought to increase surgical risks and reduce weight loss after metabolic/bariatric surgery (MBS). Electronic databases were searched between January 2013 and August 2023 for randomized controlled trials (RCT) of MBS reporting data on the safety, total weight loss (TWL), and metabolic control in patients with and without CKD. Forty-four out of 2904 articles were analyzed, representing 1470 patients. No significant differences were found in TWL after 1 year (- 19%, CI - 0.19 to - 0.18 vs.: - 15%, CI - 0.20 to - 0.09, p = 0.13) or after 5 years (- 20%, CI - 0.21 to - 0.18 vs. Group - 16%, CI - 0.28 to - 0.04, p = 0.50).Similarly, there were no significant differences in HbA1c at 1 year (- 1.06, CI - 1.37 to - 0.76 vs. Group 2: - 1.52, CI - 2.25 to - 0.79, p = 0.26) or after 5 years (- 0.97, CI - 1.53 to 0.41 vs. Group 2: - 1.09, CI - 2.21 to 0.03, p = 0.85). For fasting plasma glucose, no differences were seen at 2 years (- 30.43, CI - 60.47 to 0.39 vs. - 35.11, CI - 48.76 to - 21.46, p = 0.78) or after 5 years (- 11.24, CI - 53.38 to 30.89 vs. - 5.4, CI 20.22 to 9.42, p = 0.80). In terms of total cholesterol, no significant differences were found after 1 year (- 10.36, CI - 32.94 to 12.22 vs. - 19.80, CI - 39.46 to - 0.14, p = 0.54) or after 5 years (- 7.43, CI - 25.09 to 5.23 vs. - 21.30, CI - 43.08 to 0.49, p = 0.15). For triglycerides, both showed similar reductions after 1 year (- 76.21, CI - 112.84 to - 39.59 vs. - 78.00, CI - 100.47 to - 55.53, p = 0.94) and after 5 years (- 79.65, CI - 121.09 to - 38.21 vs. - 53.15, CI - 71.14 to - 35.16, p = 0.25). The presence of CKD in patients with obesity and T2D does not reduce the safety and efficacy of MBS.

Background: Metabolic bariatric surgery (MBS) advocates multimodal analgesia, discouraging opioid use to minimize side effects, such as nausea and vomiting, during postoperative pain management for quicker recovery. Combining erector spinae plane block (ESPB) with multimodal analgesia aims to reduce opioid consumption, improving postoperative recovery. This study aimed to compare morphine consumption between patients with severe obesity undergoing laparoscopic MBS with and without ESPB.

Methods: This study enrolled 91 patients with severe obesity who underwent laparoscopic MBS involving either sleeve gastrectomy or Roux-en-Y gastric bypass. Of these, 63 patients were included in this study. The participants were randomly allocated to either the intervention group, which received an ESPB before the standard anesthesia protocol, or the control group, which did not receive pre-anesthesia block. The primary outcome measured was 24-h morphine consumption via a patient-controlled analgesia machine. Secondary outcomes included patients' satisfaction, postoperative numerical rating score, changes over time, and quality of recovery (QoR) using the Thai QoR-35 score.

Results: We found no statistically significant difference in morphine consumption between the intervention group and the control group. Furthermore, our analysis revealed no significant between-group differences in patient satisfaction, postoperative numeric rating score, or QoR across all five aspects evaluated using the Thai QoR-35 score.

Conclusions: ESPB did not reduce morphine consumption or QoR following laparoscopic MBS. Further studies are required to confirm and identify the reasons for the ineffectiveness of ESPB.

This systematic review evaluated the safety and efficacy of reduced port laparoscopic sleeve gastrectomy and compared its potential advantages over the conventional laparoscopic approach. Eighteen eligible articles were analyzed, including thirteen cohort studies and five randomized trials (n = 2945). There were no differences in total postoperative complications [OR of 0.99 (0.72 to 1.37)] nor those classified as Clavien-Dindo ≥ IIIb. There were also no differences regarding operative time, blood loss, postoperative pain, weight loss, and improvement in comorbidities. In the reduced port group, hospital stay was slightly shorter [WDM of - 0.23 (- 0.39 to - 0.07)], and cosmetic results were better in the short term. Our meta-analysis shows reduced port sleeve gastrectomy can be safely performed in selected patients, although clinical benefits are unclear (PROSPERO (CRD42022372829)).

Introduction and purpose: It is unknown what the incidence of gastroscopy-diagnosed marginal ulceration is, while gastroscopy is a frequently chosen diagnostic modality in patients presenting with abdominal pain with a Roux-en-Y gastric bypass (RYGB) in history. The aim of this study was to examine the incidence and treatment of gastroscopy-diagnosed marginal ulceration in patients presenting with the first episode of abdominal pain after RYGB, in which gastroscopy is chosen as the first step in the diagnostic work-up.

Material and methods: A post hoc analysis was performed of a prospective cohort of 2273 patients undergoing RYGB between 2014 and 2019 in a large non-academic hospital with a dedicated bariatric unit. All patients presenting with abdominal pain > 30 days postoperatively were included. Primary outcome was gastroscopy identified marginal ulceration and treatment.

Results: One hundred two out of 498 patients presenting with abdominal pain after RYGB (20%) underwent gastroscopy as the first diagnostic step. In 84% of these patients, no marginal ulcer was found. Marginal ulceration was observed in 16/102 patients (16%). All patients underwent optimization of PPI treatment and lifestyle advises. Seven patients underwent revisional surgery, at a median of 163 days (range 80-1287) after diagnosis.

Conclusion: In a minority of patients undergoing gastroscopy for abdominal pain post-RYGB, a marginal ulceration is identified. Revisional surgery is rarely needed in all patients undergoing gastroscopy and only performed after several months when complaints persist despite PPI optimization. Only performing gastroscopy when symptoms persist safely reduces the number of gastroscopy for abdominal pain after RYGB.

Purpose: Olfaction plays a vital role in regulating nutrition, avoiding potentially dangerous situations, and modulating behavior along with interpersonal relationships. Many common disorders can have a negative impact on olfaction; one of these is obesity. Bariatric surgery induces weight loss, and current evidence suggests that it can cause improvement in olfaction. However, more information is needed regarding this topic.

Materials and methods: One hundred eighty-five patients who underwent bariatric surgery and 184 age- and gender-matched control group who did not undergo any surgery have completed a questionnaire including items from the validated Self-Reported Mini Olfactory Questionnaire.

Results: Final analysis was based on 369 patients. There was a statistically significant difference between patients before and after surgery (p < 0.05). However, there was a statistically significant difference between people who underwent surgery with < 50% excess body weight loss and the control group but none with those > 50% excess body weight loss. No significant differences were found when comparing people with and without chronic illnesses, head and neck surgery, anti-allergy drug use, and COVID-19. Before surgery, there were statistically significant differences between patients with allergic rhinitis and polyps and those without, but no significant differences were observed after surgery.

Conclusion: Patients had significantly improved olfactory scores post-surgery compared to before surgery. Patients who had > 50% excess body weight loss after surgery showed olfactory function as good as the general population represented by the control group. However, those with < 50% excess body weight loss had significantly worse olfactory scores compared to the general population.
