INTRODUCTION: Stomach-partitioning gastrojejunostomy (SPGJ) is widely performed for malignant gastric outlet obstruction; however, its utility may be limited when the obstruction is located in the distal duodenum, where digestive fluid stasis can become problematic. We devised a novel modification, termed dual-outlet stomach-partitioning gastrojejunostomy (DO-SPGJ), to address this limitation by adding a 2nd gastrojejunostomy distal to the gastric partition.
CASE PRESENTATION: A 67-year-old man with a tumor in the 3rd portion of the duodenum was diagnosed with squamous cell carcinoma without distant metastasis. The tumor was deemed unresectable due to invasion of the superior mesenteric artery. After 2 months of systemic chemotherapy, the patient developed symptoms of gastric outlet obstruction. A laparoscopic modified SPGJ was performed, involving a standard proximal gastrojejunostomy and an additional distal anastomosis between the gastric antrum and jejunum. The postoperative course was uneventful, and oral intake was successfully resumed.
CONCLUSIONS: This dual-anastomosis approach allows for both food bypass and drainage of digestive secretions, addressing the limitation of conventional SPGJ in cases of distal duodenal obstruction. The technique may also mitigate complications related to fluid stagnation, such as cholangitis or pancreatitis. This novel technique may represent a viable surgical option for select patients with unresectable malignant obstruction of the distal duodenum, especially when fluid stasis is a concern.
