Recent reports suggest a better postoperative weight gain after pylorus-preserving pancreatoduodenectomy (PPPD) compared with standard pancreatoduodenectomy (PD). Factors that could also influence postoperative weight gain, such as tumour-positive resection margins and tumour recurrence, have not been taken into account in these studies. The aim of this prospective study was to evaluate weight gain in the first 15 months after PD or PPPD and to investigate the influence of other tumour-related factors.
From 1991 to 1995, 140 patients underwent subtotal pancreatoduodenectomy; 125 patients underwent resection for malignant disease of the pancreatic head region (56 had PD and 69 PPPD). Patients' weights were evaluated in the pre-illness phase, before operation and during four postoperative phases (at 3, 7, 11 and 15 months). Weight was calculated as a percentage of the pre-illness weight. Patients were subdivided according to tumour status: PD with positive and PD with negative tumour status; PPPD with positive and PPPD with negative tumour status. Tumour-positive status was defined as either microscopically tumour-positive resection margins or radiologically or cytologically proven tumour recurrence within 2 years of surgery.
Five patients died during the hospital stay (PD, four; PPPD, one) (overall mortality rate 4 per cent). There was no difference in overall weight gain between patients having PD and PPPD. There was, however, a difference in patients with positive and negative tumour status for PD (P = 0.0003) and PPPD (P< 0.0001).
There is only a minimal difference in postoperative weight gain between patients having PD and PPPD. Differences in postoperative weight gain are related more to positive resection margins and tumour recurrence than to the type of resection.

- "It has been shown that patients can maintain a normal body weight after surgery, but it is frequently less than their preoperative body weight (25-27). Kozuscheck et al. (28) reported that 85% of patients who had undergone PPPD reached the preoperative body weight one year after surgery. "

ABSTRACT: The benefits of early enteral feeding (EEN) have been demonstrated in gastrointestinal surgery. But, the impact of EEN has not been elucidated yet. We assessed the postoperative nutritional status of patients who had undergone pancreaticoduodenectomy (PD) according to the postoperative nutritional method and compared the clinical outcomes of two methods. A prospective randomized trial was undertaken following PD. Patients were randomly divided into two groups; the EEN group received the postoperative enteral feed and the control group received the postoperative total parenteral nutrition (TPN) management. Thirty-eight patients were included in our analyses. The first day of bowel movement and time to take a normal soft diet was significantly shorter in EEN group than in TPN group. Prealbumin and transferrin were significantly reduced on post-operative day (POD) 7 and were slowly recovered until POD 90 in the TPN group than in the EEN group. EEN group rapidly recovered weight after POD 21 whereas it was gradually decreased in TPN group until POD 90. EEN after PD is associated with preservation of weight compared with TPN and impact on recovery of digestive function after PD.

ABSTRACT: HintergrundZur chirurgischen Therapie des Pankreaskopfkarzinoms und des periampullären Karzinoms stehen die pyloruserhaltende und die
klassische Operation nach Whipple („pylorus-preserving Whipple“ und „classical Whipple“) zur Verfügung.
MethodenDie vorliegende Arbeit stellt eine Erweiterung einer in Annals of Surgery publizierten systematischen Übersichtsarbeit mit Metaanalyse dar. Mithilfe einer systematischen Suchstrategie wurde in den
Datenbanken MEDLINE, EMBASE und THE Cochrane Library (CENTRAL) nach kontrollierten und randomisierten kontrollierten Studien
(RCT) zum Vergleich der klassischen Whipple-Operation und der pyloruserhaltende Pankreatikoduodenektomie gesucht. Eine auf
dem Random-effects-Modell basierende Metaanalyse wurde für die Endpunkte Überleben (Hazard Ratios, HR) und postoperative Mortalität (Odds Ratio, OR) durchgeführt. Die postoperative Lebensqualität konnte nicht quantitativ im Sinne einer Metaanalyse analysiert werden und wurde daher qualitativ zusammengefasst. Subgruppen-
und Sensitivitätsanalysen wurden nach Studientyp (RCTs, prospektive Studien, PS, retrospektive Studien, RS), Studienqualität
und Tumorlokalisation durchgeführt.
ErgebnisseDie systematische Literatursuche ergab 4503 Suchresultate, von denen 4460 nicht den Einschlusskriterien entsprachen. 23Studien
mit insgesamt 3893 Patienten wurden eingeschlossen (6RCTs, 12PS und 25RS).
Für Patienten mit Pankreaskopfkarzinom (RCTs: HR 0,80; 95%-KI 0,53–1,22; p=0,16; PS: HR 0,84; 95%-KI 0,7–1,0; p=0,95; RS:
HR 0,84; 95%-KI 0,7–1,01; p=0,21) und periampullären Karzinom (RCTs: HR 1,02; 95%-KI 0,49–2,13; p=0,3; PS: HR 1,26; 95%-KI
0,46–3,42; p=0,65; RS: HR 0,86; 95%-KI 0,6–1,24; p=0,33) zeigte sich in den einzelnen Studientypen kein Unterschied im Überleben.
Im Vergleich der beiden Operationsmethoden unterschied sich die postoperative Mortalität nicht signifikant (RCTs: OR 0,49;
95%-KI 0,17–1,4; p=0,18; PS: OR 0,63; 95%-KI 0,34–1,18; p=0,15; RS: OR 0,7; 95%-KI 0,37–1,31; p=0,27). Die postoperative Lebensqualität
wurde in den einzelnen Studien entweder als nicht unterschiedlich oder als besser nach pyloruserhaltender Operation beschrieben.
SchlussfolgerungDiese systematische Übersichtsarbeit zeigt bei insgesamt eingeschränkter Qualität der eingeschlossenen Studien keine Unterschiede
für Überleben, Mortalität und Lebensqualität im Vergleich der pyloruserhaltenden und der klassischen Whipple-Operation. Die
Bestätigung dieser Ergebnisse durch eine große, pragmatische randomisiert kontrollierte Studie erscheint sinnvoll.
BackgroundTwo surgical procedures are mainly performed for the treatment of pancreatic head cancer and periampullary carcinoma: the
classical Whipple operation and the pylorus-preserving Whipple operation.
MethodsThis manuscript represents an extension of a systematic review and meta-analysis previously published in the Annals of Surgery. A systematic literature search was performed in MEDLINE, EMBASE and the Cochrane Library (central) to identify randomized
controlled trials (RCTs) and observational studies. A meta-analysis based on a random-effects model was performed for the
hazard ratios (HR) of survival and the odds ratios (OR) of postoperative mortality. The results of the different studies on
quality of life (QoL) could not be summarized quantitatively in a meta-analysis and were therefore summarized qualitatively.
Subgroup analyses were performed by study type, RCTs, prospective cohort studies (PSs), retrospective cohort studies (RSs),
study quality and tumor localization (pancreatic head cancer versus periampullary carcinoma).
ResultsThe systematic literature search retrieved 4,503 studies of which 4,460 did not fulfill the inclusion criteria. The remaining
43 studies (6 RCTs, 12 PSs and 25 RSs) representing 3,893 patients were finally included in the review.
There was neither a significant survival difference for patients with pancreatic head cancer in the pooled estimate of the
RCTs (HR 0.80; 95% CI 0.53–1.22; p=0.16) nor in the pooled estimate of the PSs (HR 0.84; 95% CI 0.7–1.0; p=0.95) or the RSs
(HR 0.84; 95% CI 0.7–1.01; p=0.21). Survival of patients with periampullary carcinoma was not significantly different in the
RCTs (HR 1.02; 95% CI 0.49–2.13; p=0.3), the PSs (HR 1.26; 95% CI 0.46–3.42; p=0.65) or the RSs (HR 0.86; 95% CI 0.6–1.24;
Postoperative mortality was not significantly different after both types of operations (RCTs: HR 0.49; 95% CI 0.17–1.4; p=0.18;
PSs: HR 0.63; 95% CI 0.34–1.18; p=0.15; RSs: HR 0.7; 95% CI 0.37–1.31; p=0.27). QoL was reported as either the same in both
groups or in favor of the pylorus-preserving Whipple operation.
ConclusionsMortality, survival and QoL were not significantly different between the classical Whipple and the pylorus-preserving Whipple
operations. Given the poor quality of the underlying trials a pragmatic RCT is recommended to prove the findings of this systematic

ABSTRACT: Carcinoma of the pancreas has a grim prognosis even following surgical resection. Only a relatively small proportion of patients have a resectable tumour at presentation. At the present time it is uncertain whether the use of radical forms of surgery, or adjuvant therapy improve survival. It is however unlikely that either of these approaches will greatly increase the number of long term survivors. Earlier diagnosis particularly in individuals who are at greater risk of developing carcinoma of the pancreas is one way in which results might be improved. Unfortunately current imaging techniques are inadequate for the diagnosis of early disease. New molecular diagnostics techniques that can identify example mutations in oncogenes such as K-ras or deletions of tumour suppressor genes such as P53 or P16 are being developed. These tumour specific abnormalities are also a target for gene therapy. Surgery alone cannot cure any patient with pancreatic cancer but may in the future in conjunction with these new approaches.
