Association of a Modified Blumgart Anastomosis With the Incidence of Pancreatic Fistula and Operation Time After Laparoscopic Pancreatoduodenectomy: A Cohort Study

ABSTRACT:

Objective

To explore the association between a modified Blumgart anastomosis technique and the operative time and surgical complications.

Methods

This is a retrospective cohort study that analyzed the data of patients who underwent laparoscopic pancreaticoduodenectomy from January 2015 to March 2021. The primary outcome was to explore the association between the modified Blumgart anastomosis technique and operative time.

Results

A total of 282 patients were enrolled. There were 177 cases of pancreatic duct-to-mucosa anastomosis in the traditional surgery group, and 105 cases of the modified three-step Blumgart anastomosis in the modified group. There were no statistically significant differences in the general and intraoperative characteristics found between the two groups (P > 0.05). The surgical method was an independent predictor of operative time. Overall complications postsurgery were less common in the modified group than in the traditional group. The incidence of postoperative pancreatic fistula was higher in the traditional group than in the modified group (45 cases (25.4%) and 11 cases (10.5%), respectively). Fourteen cases (7.9%) in the traditional group and four case (3.8%) in the modified group had postoperative pancreatic fistula of grades B + C. The two groups had statistically significant differences (P < 0.05). The results of the linear regression showed that the type of surgical method was associated with operation time (95% CI, −73.074 to −23.941, β: −0.438, P < 0.001).

Conclusion

This modified three-step Blumgart pancreaticojejunostomy was associated with the operation time.

Project description:ImportancePostoperative pancreatic fistula is a potentially life-threatening complication after pancreatoduodenectomy. Evidence for best management is lacking.ObjectiveTo evaluate the clinical outcome of patients undergoing catheter drainage compared with relaparotomy as primary treatment for pancreatic fistula after pancreatoduodenectomy.Design, setting, and participantsA multicenter, retrospective, propensity-matched cohort study was conducted in 9 centers of the Dutch Pancreatic Cancer Group from January 1, 2005, to September 30, 2013. From a cohort of 2196 consecutive patients who underwent pancreatoduodenectomy, 309 patients with severe pancreatic fistula were included. Propensity score matching (based on sex, age, comorbidity, disease severity, and previous reinterventions) was used to minimize selection bias. Data analysis was performed from January to July 2016.ExposuresFirst intervention for pancreatic fistula: catheter drainage or relaparotomy.Main outcomes and measuresPrimary end point was in-hospital mortality; secondary end points included new-onset organ failure.ResultsOf the 309 patients included in the analysis, 209 (67.6%) were men, and mean (SD) age was 64.6 (10.1) years. Overall in-hospital mortality was 17.8% (55 patients): 227 patients (73.5%) underwent primary catheter drainage and 82 patients (26.5%) underwent primary relaparotomy. Primary catheter drainage was successful (ie, survival without relaparotomy) in 175 patients (77.1%). With propensity score matching, 64 patients undergoing primary relaparotomy were matched to 64 patients undergoing primary catheter drainage. Mortality was lower after catheter drainage (14.1% vs 35.9%; P = .007; risk ratio, 0.39; 95% CI, 0.20-0.76). The rate of new-onset single-organ failure (4.7% vs 20.3%; P = .007; risk ratio, 0.15; 95% CI, 0.03-0.60) and new-onset multiple-organ failure (15.6% vs 39.1%; P = .008; risk ratio, 0.40; 95% CI, 0.20-0.77) were also lower after primary catheter drainage.Conclusions and relevanceIn this propensity-matched cohort, catheter drainage as first intervention for severe pancreatic fistula after pancreatoduodenectomy was associated with a better clinical outcome, including lower mortality, compared with primary relaparotomy.
