Aim of the study:

To compare anastomosis techniques and outcomes in minimally invasive surgery for duodenal obstruction.

Patients:

We present 7 duodenal obstruction cases (2015-2023) treated by minimally invasive surgery.

Results:

● Type II duodenal atresia (3 patients; 1day, 1day and 7days; 2930g, 3020g and 3440g): one had a side-to-side duodenoduodenostomy using a 5mm stapler; another duodenojejunostomy required conversion to open surgery due to stapler failure; and the third had a side-to-side diamond-shaped Kimura duodenojejunostomy via laparoscopy.

● Annular pancreas (2 patients; 7 months and 1day; 5,8kg and 2330g): one underwent a side-to-side duodenoduodenostomy with a 5mm stapler and V-lock reinforcement, while the other had a termino-lateral duodenojejunostomy, converted to open surgery due to technical difficulties.

● Duodenal membrane (2 patients; 13 and 47 months; 7 and 11 kg): both underwent membrane resection and Mikulicz plasty duodenoduodenostomy; one with interrupted sutures and the other with continuous V-lock sutures.

All patients experienced an uneventful postoperative course and follow-up.

Conclusion:
The use of small-caliber surgical tools enables safe and effective minimally invasive treatment of duodenal obstruction with excellent outcomes.
