ABSTRACT: Surgical management of patients with pancreatic necrosis (PN) has evolved over the last two decades to include prophylactic antibiotics, initial medical management, and delayed surgical intervention. The purpose of this study is to identify changes in morbidity and mortality rates as our methods of surgical management have evolved. One hundred two consecutive patients (59 males and 43 females, mean age 53 +/- 16 years) with PN managed surgically were classified as group I (1993-2001), after the routine use of prophylactic antibiotics (N = 55), and group II (2002-2005), after the use of International Association of Pancreatology (IAP) guidelines for intervention (N = 47). Age, sex, etiology of pancreatitis, percent of necrosis, infected necrosis, and acute physiology and chronic health evaluation II scores were similar between groups. Despite a significant worsening of Balthazar computed tomography scoring in group II patients (p < 0.0001), operative morbidity (49 [89%] vs 34 [72%], p = 0.03), mortality (10 [18%] vs 2 [4%], p = 0.03), and hospital length of stay (38 +/- 33 days vs 26 +/- 23 days, p = 0.04) were significantly less in group II patients. Current methods of surgical management utilizing IAP guidelines have resulted in a decreased operative morbidity, mortality, and hospital length of stay in patients with PN.

ABSTRACT: Pancreatic cancer has a poor prognosis with complete surgical resection being the only therapy to offer a realistic chance for long-term survival. The aim of this study is to identify surgery-related variables that influence long-term survival. Between 1990 and 2002, 226 consecutive patients (mean age of 64+/-11 years) had resection for pancreatic adenocarcinoma. Prognostic variables in these patients were analyzed using univariate and multivariate analysis. Two hundred four patients (90%) had pancreaticoduodenectomy, 13 patients (6%) had distal pancreatectomy, and 9 patients (4%) had a TP. Stage I disease was present in 50 (22%), stage II disease in 170 (75%), and stage III disease in 6 (3%). R0 resections were achieved in 70%. Operative morbidity was 36% and 30-day mortality was 6%. Actual 1-year, 3-year, and 5-year survival rates were 49% (n=111), 14% (n=31), and 4% (n=9). Using multivariate analysis: tumor size, tumor differentiation, obtaining an R0 resection, and lack of postoperative complications were variables associated with long-term survival. Long-term survival in patients with pancreatic cancer after resection remains poor. Achieving a margin negative resection (R0) with no postoperative complications are prognostic variables that can be affected by the surgeon.

ABSTRACT: The aim of this study was to correlate the bactibilia found after preoperative biliary stenting with that of the bacteriology of postoperative infectious complications in patients with obstructive jaundice. One hundred thirty-eight patients (83% malignant and 17% benign etiologies) with obstructive jaundice had both their bile and all postoperative infectious complications cultured. Eighty-six (62%) had preoperative biliary stents (stent group) and 52 (38%) did not (no-stent group). There were no differences for age, sex, incidence of malignancy, type of operation, estimated blood loss, transfusion requirements, hospital length of stay, morbidity, or mortality rates between the two groups. Of 31 infectious complications, 23 were in the stent group and eight were in the no-stent group (P > 0.05), but only 13 (42%) infectious complications had bacteria that were also cultured from the bile. Only wound infection (P = 0.03) and bacteremia (P = 0.04) were more likely to occur in stented patients. Taken together, these data show that preoperative biliary stenting increases the incidence of bactibilia, bacteremia, and wound infection rates but does not increase morbidity, mortality, or hospital length of stay. Jaundiced patients can undergo preoperative biliary stenting while maintaining an acceptable postoperative morbidity rate.
