Study design and population
This is a retrospective study of a database with morbidly obese patients who underwent bariatric surgery between November 2007 and April 2015 in the Obesity Centre Amsterdam. Patients who underwent a primary LRYGB, primary LSG, or revisional surgery from laparoscopic adjustable gastric banding into LRYGB/LSG were included.
Data collection
The data were collected from electronic medical records and were anonymously entered in a database. The Institutional Medical Ethics Committee gave approval for this study,
Results
A total of 1788 patients underwent bariatric surgery between November 2007 and April 2015. Primary LRYBG and LSG were performed in 1361 and 118 patients, respectively, and revisional surgery was performed in 309 patients. The average follow-up consisted of 33.5 months, with a minimum and maximum period of 6 and 95 months, respectively. The postoperative course of all patients with abdominal pain was evaluated; none of the patients were lost to follow-up. Postoperative abdominal pain was present
Discussion
In 2011, an estimated 340,000 bariatric procedures were performed worldwide. Most commonly the LRYGB and the LSG [8]. With the still increasing number of bariatric procedures, knowledge of related complications is important. Unexplained abdominal pain is an increasing phenomenon in our bariatric surgical practice. Therefore, this study was performed to determine the incidence of unexplained abdominal pain and to detect predictive factors. A total of 387 patients (21.6%) experienced
Conclusion
It can be concluded that unexplained abdominal pain is an important postoperative complication that is important to acknowledge with an occurrence of 7.4 % in the bariatric surgery population. Revisional bariatric surgery was a predictive factor for the development of unexplained abdominal pain compared with explained abdominal pain, whereas the variables female sex, preoperative BMI, and type of surgery were statistically different between patients with unexplained abdominal pain and without
