Gastrojejunostomy in patients with unresectable pancreatic head cancer - the use of Roux loop significantly shortens the hospital length of stay.

Aim: To evaluate the use of the Roux loop on the postoperative course in patients submitted for gastroenteroanastomosis (GE).

Methods: Non-jaundiced patients (n = 41) operated on in the Department of General and Transplant Surgery in Lodz, between January 2010 and December 2011 were enrolled. The tumor was considered unresectable when liver metastases or major vascular involvement were confirmed. Patients were randomized to receive Roux (n = 21) or conventional GE (n = 20) on a prophylactic basis.

Results: The mean time to nasogastric tube withdrawal in Roux GE group was shorter (1.4 ± 0.75 vs 2.8 ± 1.1, P < 0.001). Time to starting oral liquids, soft diet and regular diet were decreased (2.3 ± 0.86 vs 3.45 ± 1.19; P < 0.001; 3.3 ± 0.73 vs 4.4 ± 1.23, P < 0.001 and 4.5 ± 0.76 vs 5.6 ± 1.42, P = 0.002; respectively). The Roux GE group had a lower use of prokinetics (10 mg thrice daily for 2.2 ± 1.8 d vs 3.7 ± 2.6 d, P = 0.044; total 62 ± 49 mg vs 111 ± 79 mg, P = 0.025). The mean hospitalization time following Roux GE was shorter (7.7 d vs 9.6 d, P = 0.006). Delayed gastric emptying (DGE) was confirmed in 20% after conventional GE but in none of the patients following Roux GE.

Conclusion: Roux gastrojejunostomy during open abdomen exploration in patients with unresectable pancreatic cancer is easy to perform, decreases the incidence of DGE and lowers hospitalization time.
