Laparoscopic gastro- and hepaticojejunostomy for palliation of pancreatic cancer: a case controlled study

Most patients presenting with pancreatic cancer are irresectable at the time the diagnosis is made. Therefore, they are in need of palliative treatment that can guarantee minimal morbidity, mortality, and hospital stay. To address this need, we designed a study to test the feasibility of laparoscopic gastroenterostomy and hepaticojejunostomy and to compare their results with those achieved with open techniques.

We performed a case control study of a new concept in laparoscopic palliation based on the findings of preoperative imaging and diagnostic laparoscopy. Laparoscopic side-to-side gastroenterostomy and end-to-side hepaticojejunostomy (Roux-en-Y) were done in irresectable cases. Of 14 patients who underwent laparoscopic palliation, three had a laparoscopic double bypass, seven had a gastroenterostomy, and four underwent staging laparoscopy only. The results were compared with a population of 14 matched patients who had conventional palliative procedures.

Postoperative morbidity was 7% vs 43% for laparoscopic and open palliation, respectively (p < 0.05). There were no mortalities in the laparoscopic group, as compared to 29% in the group who had open bypass surgery (p < 0.05). Postoperative hospital stay averaged 9 days in the laparoscopic group and 21 days in the open group (p < 0.06). Operating time tended to be shorter in the laparoscopic group (p < 0.25). Morphine derivatives were necessary for a significantly shorter period after laparoscopic surgery (p < 0.03).

Our preliminary experience strongly suggests that laparoscopic palliation can reduce the three major drawbacks of open bypass surgery-i.e., high morbidity, high mortality, and long hospital stay.
