Zusammenfassung

Hintergrund

Klammernaht- oder Anastomoseninsuffizienzen nach bariatrischen Eingriffen stellen für die Patienten eine ernstzunehmende Komplikation dar. Die Röntgendurchleuchtungsuntersuchung mit oraler Aufnahme eines wasserlöslichen Kontrastmittels (DL-U) ist eine Möglichkeit, Insuffizienzen zu diagnostizieren. Ziel dieser Studie ist die Bewertung routinemäßiger DL-U nach primären bariatrischen Eingriffen im Hinblick auf die Detektion postoperativer Komplikationen.

Methodik

Von 01/2009 bis 12/2014 wurden 658 bariatrische Eingriffe durchgeführt. 442 Primäreingriffe, darunter 307 laparoskopische Sleeve-Gastrektomien (LSG) und 135 laparoskopische Roux-Y-Magenbypässe (LRYGB), wurden in die Studie eingeschlossen. Bis 12/2012 erfolgte eine routinemäßige DL-U zwischen dem 1. und 3. postoperativen Tag unabhängig von der klinischen Symptomatik. Die Auswertung der DL-U erfasste die Erkennung von Komplikationen wie Insuffizienzen und Stenosen.

Ergebnisse

Im Untersuchungszeitraum traten 8 Klammernahtinsuffizienzen (2,6 %) nach Sleeve-Gastrektomie auf. Des Weiteren wurden je eine Insuffizienz der Gastrojejunostomie (0,7 %) und eine der Jejunojejunostomie (0,7 %) nach den Magenbypässen diagnostiziert. Alle Patienten wurden durch die klinische Symptomatik auffällig. In einem Fall wurde die Insuffizienz in der Routine-DL-U nachgewiesen, in 9 Fällen war die postoperative Routineröntgendiagnostik unauffällig. Bei keinem Patienten erfolgte ein radiologischer Insuffizienznachweis bei unauffälligem klinischem Befund.

Schlussfolgerung

Routinemäßige, frühpostoperative DL-U nach bariatrischen Eingriffen sind zur Detektion von Insuffizienzen beim asymptomatischen Patienten nicht geeignet.

Abstract

Background

Staple line and anastomotic leakages are life-threatening complications after bariatric surgery. Upper gastrointestinal (GI) tract X-ray examination with oral administration of a water-soluble contrast agent can be used to detect leaks. The aim of this study was to evaluate the impact of routine upper GI tract fluoroscopy after primary bariatric surgery.

Methods

Between January 2009 and December 2014 a total of 658 bariatric interventions were carried out of which 442 were primary bariatric operations. Included in this single center study were 307 sleeve gastrectomies and 135 Roux-en-Y gastric bypasses. Up to December 2012 upper GI tract fluoroscopy was performed routinely between the first and third postoperative days and the detection of leakages was evaluated.

Results

In the investigation period 8 leakages (2.6 %) after sleeve gastrectomy, 1 anastomotic leakage in gastrojejunostomy and 1 in jejunojejunostomy after Roux-en-Y gastric bypass occurred. All patients developed clinical symptoms, such as abdominal pain, tachycardia or fever. In one case the leakage was detected by upper GI fluoroscopy and in nine cases radiological findings were unremarkable. No leakages were detected in asymptomatic patients.

Conclusion

Routine upper GI fluoroscopy is not recommended for uneventful postoperative courses after primary bariatric surgery.
