Small bowel obstruction secondary to adipose tissue herniation through gastric band tubing loop. An unusual case presentation

Ann Ital Chir. 2020 Sep 14:9:S2239253X2003457X.

Abstract

Background: Laparoscopic adjustable gastric band complications like oesophageal dilatation, intractable nausea and vomiting, band migration, late slippages, and port problems with a cumulative rate of 19.2%. Rarely, LAGB complications may be related to the connection tube system and in this case the clinical presentation and the effects of the problem can generate difficulties in diagnosis.

Methods: A 47 years old woman who had a LAGB placed 2 years before the symptoms was admitted in our centre with nausea, vomit, leukocytosis and distended abdomen with a generalized tenderness. Computed tomography images showed an anomalous course of banding tube and a contemporary compression of a small bowel tract secondary to the traction exerted by an adipose tissue band attracted by the tube.

Results: A laparoscopic exploration of the abdominal cavity showed a tight loop of LAGB tubing causing a small bowel obstruction with an ischemic damage, so surgeons provided to LAGB removal and a 50 cm ileum resection CONCLUSIONS: Small bowel obstruction resulting from LAGB tubing is an uncommon complication which was reported in few cases. Although bariatric surgery currently represents the best treatment option for morbid obesity and its related- diseases, peri- and post-operative complications have always to be taken into account.

Key words: Adjustable gastric band complications, Bariatric surgery, Bowel obstruction, CT scan, LAGB tube.

Al giorno d’oggi, il bendaggio gastrico regolabile laparoscopico (LAGB) sta assistendo ad un progressivo declino nella maggior parte dei centri di chirurgia bariatrica; questo è principalmente dovuto ai suoi scarsi risultati, nel follow-up a lungo termine, in termini di riduzione dell’Indice di massa corporea (IMC) e all’ampio spettro delle sue complicanze. Quello che viene presentato è un raro caso di complicanza da LAGB correlata al suo tubo di collegamento con il port di regolazione esterno; nel dettaglio, il decorso anomalo del catetere del dispositivo ha determinato una compressione di un’ansa digiunale per trazione esercitata da una banda di tessuto adiposo attratta dal catetere stesso. La presentazione clinica e gli effetti delle complicanze legate al bendaggio gastrico possono generare difficoltà nella diagnosi e nel trattamento; per tali motivi risulta fondamentale, quando le condizioni cliniche lo permettano e la diagnosi non sia chiara, richiedere l’intervento di uno specialista in chirurgia bariatrica.
