“…However, a relatively recent multi-institutional survey on 2678 patients with a mid-term (5 years) follow-up showed that the anastomotic stenosis may occur also as a late complication (from month 2 up to the 10 years) [ 54 ] related to adhesion subsequent to bariatric surgery [ 55 ].…”

Bariatric surgery has demonstrated a higher rate of success than other nonsurgical treatments in selected patients with obesity; however, like all medical procedures, postoperative complications may occur, ranging between 2 and 10% and, although rare, they can be life threatening. Complications may be unspecific (any surgery-related complications) or specific (linked to the specific surgical procedure) and can be distinguished as common, less common, and unexpected. According to the onset, they may be acute, when occurring in the first 30 days after surgery, or chronic, with a presentation after 30 days from the procedure. The aim of this pictorial essay is to review the radiological aspects of surgical techniques usually performed and the possible complications, in order to make radiologists more confident with the postsurgical anatomy and with the normal and abnormal imaging findings.

Laparoscopic sleeve gastrectomy (SG) is the most commonly performed bariatric procedure. The primary and insidious early post-SG complication is the gastric leak (GL). In literature, there are many studies describing the endoscopic stent placement as treatment of GL and few studies about stent placement performed by interventional radiology under fluoroscopic guide. Our aims were to describe the radiological stent placement technique, to compare endoscopic and radiological stent placement, to illustrate normal diagnostic features and summarise the incidence of complications after stent placement, removal, and their imaging features. This was a single centre retrospective study of 595 patients who underwent SG between 2011 and 2019. Inclusion criteria: patients who developed GL after SG and treated with gastro-oesophageal stent placement by endoscopy or interventional radiology; availability of medical history and imaging studies; follow-up time after stent removal (1 year). The rates of technical success, clinical success and complications after stent placement and removal were collected and compared between the two methods of stent positioning. A total of 17/595 (2.8%) patients developed a radiologically diagnosed GL after SG. The type II-III GLs (15/17) were treated with endoscopic or radiological stent placement. 9/15 (60%/Group A) patients underwent gastro-oesophageal stenting by interventional radiology and 6/15 (40%/Group B) were treated with endoscopic stent placement. The technical and clinical success rate was 100% for both groups. Stent migration occurred in 22% and 27% for Group A and B respectively. Post-extraction stenosis was the main late complication, occurring in 22% in Group A and 0% in Group B. Gastro-esophageal stent placement performed by interventional radiologists is a valid "mini-invasive" treatment for GL. This procedure is not inferior to endoscopic positioning regarding efficacy, periprocedural and postprocedural complication rate. It's necessary to be familiar with radiological findings after stent placement and removal. Computed tomography (CT) scan is the main radiological technique to identify stent placement complications. Upper gastrointestinal (UGI) series are the first radiological procedures used to detect late complications after stent removal.
