Abstract:Purpose
Staple line leak (SLL) is a serious complication after sleeve gastrectomy (SG). Common endoscopic treatment options include self-expandable metallic stent (SEMS), endoscopic internal drainage (EID), and endoscopic closure. The endoscopic negative pressure therapy (ENPT) is a promising treatment option combining temporary sealing of the defect with drainage of the inflammatory bed. In this study, we compare the outcome of ENPT and SEMS for the treatment of SLL following SG.

“…EID can be used in acute and chronic leaks with associated collections; better results may be achieved with intra-abdominal leaks and when several pigtail stents can be delivered side by side in an attempt to occlude the leak defect. Some see no value in routine stent exchange in EID unless necrosectomy is also performed [ 74 , 75 ].…”
Background
Patients presenting with acute abdominal pain that occurs after months or years following bariatric surgery may present for assessment and management in the local emergency units. Due to the large variety of surgical bariatric techniques, emergency surgeons have to be aware of the main functional outcomes and long-term surgical complications following the most performed bariatric surgical procedures. The purpose of these evidence-based guidelines is to present a consensus position from members of the WSES in collaboration with IFSO bariatric experienced surgeons, on the management of acute abdomen after bariatric surgery focusing on long-term complications in patients who have undergone laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass.
Method
A working group of experienced general, acute care, and bariatric surgeons was created to carry out a systematic review of the literature following the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P) and to answer the PICO questions formulated after the Operative management in bariatric acute abdomen survey. The literature search was limited to late/long-term complications following laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass.
Conclusions
The acute abdomen after bariatric surgery is a common cause of admission in emergency departments. Knowledge of the most common late/long-term complications (> 4 weeks after surgical procedure) following sleeve gastrectomy and Roux-en-Y gastric bypass and their anatomy leads to a focused management in the emergency setting with good outcomes and decreased morbidity and mortality rates. A close collaboration between emergency surgeons, radiologists, endoscopists, and anesthesiologists is mandatory in the management of this group of patients in the emergency setting.

“…Most evidence for EVT has been gained for treating colorectal and esophageal leakages. However, single-center reports exist for regular use of EVT for duodenal leakages and suture insufficiencies after bariatric surgery [61][62][63]. This was described as therapeutically superior to gastric stenting.…”

<b><i>Background:</i></b> Spontaneous or postoperative gastrointestinal defects are still life-threatening complications with elevated morbidity and mortality. Recently, endoscopic treatment options – up and foremost endoscopic vacuum therapy (EVT) – have become increasingly popular and have shown promising results in these patients. <b><i>Methods:</i></b> We performed an electronic systematic search of the MEDLINE databases (PubMed, EMBASE, and Cochrane) and searched for studies evaluating endoscopic options for the treatment of esophageal and colorectal leakages and/or perforations until March 2022. <b><i>Results:</i></b> The closure rate of both esophageal and colorectal defects by EVT is high and even exceeds the results of surgical revision in parts. Out of all endoscopic treatment options, EVT shows most evidence and appears to have the highest therapeutic success rates. Furthermore, EVT for both indications had a low rate of serious complications without relevant in-hospital mortality. In selected patients, EVT can be applied without fecal diversion and transferred to an outpatient setting. <b><i>Conclusion:</i></b> Despite multiple endoscopic treatment options, EVT is increasingly becoming the new gold standard in endoscopic treatment of extraperitoneal defects of the upper and lower GI tract with localized peritonitis or mediastinitis and without close proximity to major blood vessels. However, further prospective, comparative studies are needed to strengthen the current evidence.

ZusammenfassungPostoperative Leckagen nach Ösophagus‑, Magen- oder Kolon- bzw. Rektumchirurgie stellen schwerwiegende chirurgische Komplikationen mit einer hohen Morbidität und Mortalität dar. Leckagen werden zumeist durch eine Kombination aus klinischer Beobachtung, Infektionsparametern sowie endoskopischen und schnittbildgebenden Verfahren diagnostiziert. Die Therapie ist bei intraperitonealen Leckagen chirurgisch, bei retroperitonealen bzw. mediastinalen Leckagen in einem interdisziplinären Setting überwiegend interventionell endoskopisch. Hier stehen der Defektverschluss durch die Abdichtung mittels selbstexpandierender gecoverter Stents mit gleichzeitiger externer extraluminaler Drainage sowie der Defektverschluss mit simultaner innerer Drainage und endoskopischer Unterdrucktherapie als vorrangige Methoden zur Verfügung.
