Full-text for Emory users.
Results: There were no differences between drain and no-drain cohorts in demographics, comorbidities, pathology, pancreatic duct size, pancreas texture, baseline quality of life, or operative technique. PD without intraperitoneal drainage was associated with an increase in the number of complications per patient [1 (0-2) vs 2 (1-4), P = 0.029]; an increase in the number of patients who had at least 1 ≥grade 2 complication [35 (52%) vs 47 (68%), P = 0.047]; and a higher average complication severity [2 (0-2) vs 2 (1-3), P = 0.027]. PD without intraperitoneal drainage was associated with a higher incidence of gastroparesis, intra-abdominal fluid collection, intra-abdominal abscess (10% vs 25%, P = 0.027), severe (≥grade 2) diarrhea, need for a postoperative percutaneous drain, and a prolonged length of stay. The Data Safety Monitoring Board stopped the study early because of an increase in mortality from 3% to 12% in the patients undergoing PD without intraperitoneal drainage.
Conclusions: This study provides level 1 data, suggesting that elimination of intraperitoneal drainage in all cases of PD increases the frequency and severity of complications.

This week’s discussion included risk scoring and management of postoperative pancreatic fistula.

Prediction: “Biochemical markers of POP after pancreatic resection are evident from the first postoperative day. These include serum amylase and lipase, and urinary trypsinogen-2. In an observational study of 61 patients undergoing pancreatic resection, the presence of POP on the first postoperative day as determined by these markers was found to be a strong predictor of the development of POPF (OR 17.81, 95% CI 2.17–145.9) 
One discussion this week included early vs late drain removal in pancreatectomy.

Summary: Early drain removal after pancreatoduodenectomy, when guided by postoperative day (POD) 1 drain fluid amylase (DFA-1), is associated with reduced rates of clinically relevant postoperative pancreatic fistula (CR-POPF).
One discussion this week involved etiologies of postpancreatectomy hemorrhage.

Summary: With the purpose of creating algorithms for managing postpancreatectomy hemorrhage (PPH), Yekebas et al (2007) restrospectively analyzed more than 1669 pancreatic resections conducted between 1992 and 2006. They concluded that the prognosis of postpancreatectomy hemorrhage (PPH) is primarily dependent on the presence of “preceding pancreatic fistula” (p.269).
