Impenetrable Abdomen: A Case Report of Endoscopic Sleeve Gastroplasty Performed in Patient with Huge Paramedian Laparocele.

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.
