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.

Purpose: Low socioeconomic status (SES) correlates with higher obesity rates and challenges in accessing treatments like bariatric surgery (BS). This study aims to assess SES's influence on medium-term BS outcomes in a setting of universal healthcare, ensuring equitable treatment access.

Material and methods: We conducted a retrospective analysis of 193 BS patients (1997-2018) at a tertiary care hospital. Weight loss was expressed as change in % total weight loss (%TWL) and excess body weight (EBW) loss. Successful BS was defined as > 50% EBW loss. SES was gauged using quartiles of the Spanish Deprivation Index. A multivariable Cox regression model evaluated SES impact on BS success over follow-up.

Results: The mean follow-up was 6.9 ± 4.6 years; patients averaged 43.9 ± 11.8 years, with 29.7% men. Preoperative BMI was 48.2 ± 8.2 kg/m². At follow-up, BMI was 33.9 ± 6.6 kg/m², with 29.3 ± 12.02% of %TWL. No SES quartile differences in BS success were noted at follow-up (log rank p = 0.960). Cox regression revealed no SES disparities in BS outcomes post-adjustment. However, female sex (HR 1.903; p = 0.009) and diabetes mellitus (HR = 0.504; p = 0.010) correlated with weight-related outcomes.

Conclusion: In a universal healthcare system with equitable treatment access, medium-term BS outcomes remain consistent irrespective of patients' socioeconomic status.

Introduction: Bariatric surgical techniques have demonstrated scientific efficacy and interventional safety; however, these approaches are not universally appropriate for all patients. The term "impenetrable abdomen" refers to the inability to achieve surgical access to the abdominal cavity, a condition that may arise from several underlying factors. Endoscopic sleeve gastroplasty (ESG) is proposed as a safe and effective technique in this subgroup of patients with obesity.

Materials and methods: A 56-year-old Caucasian woman with an impenetrable abdomen due to the presence of a large left paramedian laparocele underwent ESG (Fig. 1) to our unit. An abdominal computed tomography (CT) scan revealed a substantial laparocele in the left paramedian region, involving the tenuous loops, mesentery, and part of the transverse colon. The patient body mass index (BMI) at presentation was 47.15 kg/m² (116 kg per 1.57 m). Comorbidities included obstructive sleep apnea syndrome (OSAS), requiring nocturnal continuous positive airway pressure (CPAP) therapy, hepatic steatosis, hypertension, hypertriglyceridemia, and hypovitaminosis D. The case was discussed with our multidisciplinary board team (MDT), who agreed to proceed with the ESG. The endoscopic procedure was performed in the supine position, using the Overstitch device and lasted 58 min. No intraprocedural or post-procedural complications/adverse events have been observed. The patient resumed a liquid diet on the first postoperative day and was discharged from the hospital 24 h after the procedure in good clinical condition.

Results: Regular outpatient follow-up visits showed significant reduction of the BMI at 6 months post-procedure with a value of 34.9 kg/m² compared with the initial value of 47.1 kg/m². Additionally, the patient's use of nocturnal CPAP for OSAS was successfully discontinued suggesting an improvement in her respiratory condition as a result of weight loss. Moreover, there was a notable reduction in the pharmacological management required for arterial hypertension. These outcomes underscore the positive impact of selecting the most appropriate therapeutic strategy for each patient with obesity through a multidisciplinary team approach.

Conclusion: In our experience, we confirm that endoscopic sleeve gastroplasty is both feasible and safe in patients presenting with an impenetrable abdomen. Despite the minimally invasive approach, this technique has proven effective in terms of body weight loss and reduction of obesity related compared with bariatric surgery.
