The primary endpoint of this study, the median nutritional
balance (coverage of calories per patient related the energy requirements
during hospitalization) of the whole collective was
93.4% (range: 100%e69.3%), which represents an average deficit of
754 kcal (range: 0e16350 kcal) per patient over the whole hospitalization
(Fig. 1). Complete caloric intake of 25 kcal/kg/d was
achieved in 1081 out of 1516 patient days (71.3%). Analyzing the
most intense catabolic stress period of the first 7 days, caloric requirements
were covered in 6 out of 7 days (Table 2).
Postoperative outcomes are shown in Table 3. Four patients
(5.8%) died postoperatively. Reasons for mortality were septic
shock in three patients and multi organ failure initiated by a portal
vein thrombosis in one patient. The rate ofmajor complicationswas
21.7% (15 out of 69). DGE occurred in 13 patients (18.8%), whereas
two had to undergo endoscopic decompression (2.9%). The other 11
patients were treated conservatively (metoclopramide, erythromycin).
The fistula rate of pancreatic anastomosis was 15.9% (grade
A: 0, grade B: 7, grade C: 4). One patient developed an additional
bile leak grade C (1.4%). No PPH was observed. The mean length of
hospital stay was 23.2 days, with a mean of 6.8 days in the ICU. The
first bowel movement was observed on postoperative day 5. More
than 50% of the patients were discharged directly to their homes.
