Jejunogastric intussusception after distal gastrectomy with Roux-en-Y reconstruction: A case report.

INTRODUCTION

Jejunogastric intussusception is a rare complication after gastric operation. Intussusception after gastric operation occurs mostly at the gastrojejunal anastomosis site and Braun anastomosis site of Billroth II reconstruction, and at the Y anastomosis site of Roux-en-Y reconstruction. However, jejunogastric intussusception after distal gastrectomy with Roux-en-Y reconstruction is very rare. We report a surgical case of jejunogastric intussusception after distal gastrectomy for gastric cancer treatment.

PRESENTATION OF CASE

An 82-year-old woman underwent laparoscopic distal gastrectomy for early gastric cancer treatment. Reconstruction was performed using Roux-en-Y anastomosis. Oral intake was started on postoperative day 4, however vomiting and high-grade fever occurred on postoperative day 12, after which oral intake became difficult.

DISCUSSION

Anastomotic stenosis of the gastrojejunostomy was suspected, and various examinations were performed. Gastroendoscopy and computed tomography revealed an elevated lesion with ring-like folds protruding through the anastomosis site into the remnant stomach. Reoperation was performed on postoperative day 28 after a diagnosis of jejunogastric intussusception was made. It failed to reduce the intussusception, so partial resection of the gastrojejunal anastomosis was performed and Roux-en-Y reconstruction was repeated. Reconstruction was conducted after taking into consideration the recurrence of intussusception.

CONCLUSION

Jejunogastric intussusceptions after distal gastrectomy is a rare complication; however, when it occurs, early diagnosis and appropriate management are necessary.
