Association of Preoperative Biliary Drainage With Postoperative Outcome Following Pancreaticoduodenectomy

OBJECTIVE: To determine whether preoperative biliary instrumentation and preoperative biliary drainage are associated with increased morbidity and mortality rates after pancreaticoduodenectomy. SUMMARY BACKGROUND DATA: Pancreaticoduodenectomy is accompanied by a considerable rate of postoperative complications and potential death. Controversy exists regarding the impact of preoperative biliary instrumentation and preoperative biliary drainage on morbidity and mortality rates after pancreaticoduodenectomy. METHODS: Two hundred forty consecutive cases of pancreaticoduodenectomy performed between January 1994 and January 1997 were analyzed. Multiple preoperative, intraoperative, and postoperative variables were examined. Pearson chi square analysis or Fisher's exact test, when appropriate, was used for univariate comparison of all variables. Logistic regression was used for multivariate analysis. RESULTS: One hundred seventy-five patients (73%) underwent preoperative biliary instrumentation (endoscopic, percutaneous, or surgical instrumentation). One hundred twenty-six patients (53%) underwent preoperative biliary drainage (endoscopic stents, percutaneous drains/stents, or surgical drainage). The overall postoperative morbidity rate after pancreaticoduodenectomy was 48% (114/240). Infectious complications occurred in 34% (81/240) of patients. Intraabdominal abscess occurred in 14% (33/240) of patients. The postoperative mortality rate was 5% (12/240). Preoperative biliary drainage was determined to be the only statistically significant variable associated with complications (p = 0.025), infectious complications (p = 0.014), intraabdominal abscess (p = 0.022), and postoperative death (p = 0.037). Preoperative biliary instrumentation alone was not associated with complications, infectious complications, intraabdominal abscess, or postoperative death. CONCLUSIONS: Preoperative biliary drainage, but not preoperative biliary instrumentation alone, is associated with increased morbidity and mortality rates in patients undergoing pancreaticoduodenectomy. This suggests that preoperative biliary drainage should be avoided whenever possible in patients with potentially resectable pancreatic and peripancreatic lesions. Such a change in current preoperative management may improve patient outcome after pancreaticoduodenectomy.     

Effect of Preoperative Biliary Decompression on Pancreaticoduodenectomy-Associated Morbidity in 300 Consecutive Patients

OBJECTIVE: To examine the relationship between preoperative biliary drainage and the morbidity and mortality associated with pancreaticoduodenectomy. SUMMARY BACKGROUND DATA: Recent reports have suggested that preoperative biliary drainage increases the perioperative morbidity and mortality rates of pancreaticoduodenectomy. METHODS: Peri-operative morbidity and mortality were evaluated in 300 consecutive patients who underwent pancreaticoduodenectomy. Univariate and multivariate logistic regression analyses were done to evaluate the relationship between preoperative biliary decompression and the following end points: any complication, any major complication, infectious complications, intraabdominal abscess, pancreaticojejunal anastomotic leak, wound infection, and postoperative death. RESULTS: Preoperative prosthetic biliary drainage was performed in 172 patients (57%) (stent group), 35 patients (12%) underwent surgical biliary bypass performed during prereferral laparotomy, and the remaining 93 patients (31%) (no-stent group) did not undergo any form of preoperative biliary decompression. The overall surgical death rate was 1% (four patients); the number of deaths was too small for multivariate analysis. By multivariate logistic regression, no differences were found between the stent and no-stent groups in the incidence of all complications, major complications, infectious complications, intraabdominal abscess, or pancreaticojejunal anastomotic leak. Wound infections were more common in the stent group than the no-stent group. CONCLUSIONS: Preoperative biliary decompression increases the risk for postoperative wound infections after pancreaticoduodenectomy. However, there was no increase in the risk of major postoperative complications or death associated with preoperative stent placement. Patients with extrahepatic biliary obstruction do not necessarily require immediate laparotomy to undergo pancreaticoduodenectomy with acceptable morbidity and mortality rates; such patients can be treated by endoscopic biliary drainage without concern for increased major complications and death associated with subsequent pancreaticoduodenectomy.     

Effect of preoperative biliary stenting on immediate outcome after pancreaticoduodenectomy

BACKGROUND: Preoperative biliary stenting is associated with bacterial contamination of bile and an increased rate of infectious complications after pancreaticoduodenectomy. Preoperative drainage has been found to have conflicting effects on morbidity and mortality, and no studies have been published on the effect of stent complications and duration of stenting on postoperative outcome. This study examined the effects of preoperative biliary stenting on early outcome after pancreaticoduodenectomy. METHODS: Details of 144 patients undergoing pancreaticoduodenectomy from 1992 to 2001 were entered into a database. Variables included biliary stenting, duration of stenting, stent complications and bile culture results. Details of surgery and postoperative complications were noted. Patients were grouped as stented and non-stented. Factors likely to affect postoperative mortality and morbidity were analysed. RESULTS: Preoperative biliary stenting was performed in 74 of the 144 patients; post-stenting complications developed in 18 patients (24 per cent) before surgery. After surgery there were nine deaths (6.3 per cent) and 60 (41.7 per cent) of the 144 patients developed complications, with no significant difference in morbidity rate between stented and non-stented patients. Logistic regression showed that a positive intraoperative bile culture was the only factor significantly associated with operative morbidity (P < 0.001) and mortality (P = 0.019). Biliary stenting was not significantly associated with a positive culture (P = 0.073), but stenting that resulted in complications (P = 0.006) and drainage for less than 6 weeks (P = 0.011) was associated with significantly greater culture positivity. Stenting followed by complications was shown by logistic regression to be the only factor significantly associated with a positive culture (P = 0.012). CONCLUSION: A positive intraoperative bile culture was associated with higher morbidity and mortality rates following pancreaticoduodenectomy. A positive culture in the stented group was related to stent complications and duration of stenting. Uncomplicated stenting was not associated with increased morbidity or mortality.     

The effect of preoperative biliary stenting on postoperative complications after pancreaticoduodenectomy

BACKGROUND: Preoperative biliary drainage (PBD) in jaundiced patients undergoing pancreaticoduodenectomy remains controversial. METHODS: Patients presenting with obstructive jaundice who subsequently underwent pancreaticoduodenectomy from January 1996 to June 2002 were included in the study (n = 212). Patients with preoperative biliary stents (n = 154) were compared with patients without preoperative drainage (n = 58). RESULTS: Patients in the stented group required a longer operative time (mean 6.8 hours versus 6.5 hours) and had greater intraoperative blood loss (mean 1207 mL versus 1122 mL) compared with the unstented group, (P = 0.046 and 0.018). No differences were found with respect to operative mortality (2%), incidence of pancreatic fistula (10% versus 14%), or intraabdominal abscess (7% versus 5%). Wound infection occurred more often in the stented group (8% versus 0%, P = 0.039). CONCLUSIONS: PBD was associated with increased operative time, intraoperative blood loss, and incidence of wound infection. Although PBD did not increase major postoperative morbidity and mortality, it should be used selectively in patients undergoing pancreaticoduodenectomy.     

PANCREATICODUODENECTOMY: DOES PREOPERATIVE BILIARY DRAINAGE,METHOD OF PANCREATIC RECONSTRUCTION OR AGE INFLUENCE PERIOPERATIVE OUTCOME? A RETROSPECTIVE STUDY OF 104 CONSECUTIVE CASES

BACKGROUND: Whether preoperative biliary drainage (PBD) is beneficial in reducing complications after pancreaticoduodenectomy is controversial. There remains a reluctance to consider pancreaticoduodenectomy in older patients. The major source of morbidity and potential mortality after pancreaticoduodenectomy is pancreatic fistula, which is caused by difficulties associated with the pancreatic anastomosis. The purpose of this study was to examine the effect of PBD, patient age and method of pancreatico-enteric reconstruction on postoperative morbidity and mortality. METHODS: A total of 104 consecutive patients undergoing pancreaticoduodenectomy between November 1992 and November 2004 were identified from a prospectively collected database. Multiple preoperative and intraoperative variables were examined and their relationship to postoperative outcome was analysed. RESULTS: Postoperative mortality was <1%. Forty-three patients (43%) suffered a total of 85 complications. Median length of stay was 12.5 days (range, 1-88 days). The group undergoing PBD did not have higher rates of infectious complication (12 vs 19%; P = 0.34) or overall complication (41 vs 42%; P = 0.88) compared with the undrained group. Rate of anastomotic leak (18 vs 4%; P = 0.045) and anaemia requiring transfusion (41 vs 9%; P = 0.001) were significantly higher in the pancreaticojejunostomy group compared with the pancreaticogastrostomy group. Patients over the age of 70 years did not have higher rates of complication (44 vs 41%, P = 0.5) or postoperative length of stay. CONCLUSION: Preoperative biliary drainage was not associated with increased postoperative complications. Pancreaticogastrostomy after pancreaticoduodenectomy is a safe and reliable method of reconstruction. Finally, pancreaticoduodenectomy can be carried out with acceptable rates of postoperative morbidity and mortality in selected patients over 70 years of age.     

Pancreaticoduodenectomy: Role of interventional radiologists in managing patients and complications

Although the mortality rate after pancreaticoduodenectomy has decreased, the morbidity rate remains high. Major morbidity is often managed with the aid of interventional radiologists. The objective of this study was to evaluate the cooperative roles of interventional radiologists and pancreatic surgeons in complex pancreatic surgery, specifically pancreaticoduodenectomy. Our pancreaticoduodenectomy database was reviewed for all patients undergoing pancreaticoduodenectomy between January 1, 1995 and December 31, 2000. The interventional radiologic procedures for each patient were evaluated. A total of 1061 patients underwent pancreaticoduodenectomy. The overall mortality and morbidity rates were 2.3% and 35%, respectively. Five hundred ninety patients (56%) had no interventional radiologic procedures, whereas 471 patients (44%) had interventional radiologic procedures. Of those, 342 (32%) had preoperative biliary drainage (PBD) and 129 (12%) required postoperative interventional radiologic procedures. Percutaneous aspiration/catheter drainage was required in 84 patients for intra-abdominal abscess, biloma, or lymphocele, with 24 requiring two or more abscess drains. Thirty-nine patients underwent postoperative PBD for bile leaks due to anastomotic disruption, undrained biliary segments, or T-tube/ bile stent dislodgment. Eighteen patients had hemobilia/gastrointestinal bleeding treated by angiography with embolization. The reoperation rate for the entire cohort of 1061 patients was 4.1% (n = 43). Nineteen of the 129 patients (15%) requiring postoperative radiologic intervention required reoperation. Although 4 of 18 patients who required embolization for bleeding subsequently required surgical intervention for the same reason, only 4 of 84 patients undergoing abscess drainage later required operation for anastomotic disruption or unsuccessful percutaneous drainage. As would be expected, the patients who required postoperative radiologic intervention (n = 129) had a higher incidence of postoperative complications including pancreatic fistula (20% vs. 6%, P <0.01), bile leakage (22% vs. 1%, P< 0.01), and wound infection (16% vs. 8%, P < 0.01). With the complications in these 129 patients, the postoperative mortality rate was only 6.2% compared to 1.7% in patients who did not require radiologic intervention (n = 932, P< 0.01). The median postoperative length of stay was 15 days in those patients requiring postoperative radiologic intervention, 10 days in those not requiring intervention (P< 0.01; postoperative interventional radiology vs. no postoperative interventional radiology), and 29.5 days for patients needing reoperation. Interventional radiologists play a critical role in the management of some patients undergoing pancreaticoduodenectomy. Although complications such as anastomotic leaks, abscess formation, and bleeding can result in increased mortality and a longer hospital stay, the skills of the interventional radiology team provide expert management of some life-threatening complications, thus avoiding reoperation, speeding recovery times, and minimizing morbidity.

Effect of bile contamination on immediate outcomes after pancreaticoduodenectomy for tumor

BACKGROUND: The influence of preoperative biliary drainage on the postoperative course of patients undergoing pancreaticoduodenectomy (PD) remains controversial. Among drawbacks of biliary drainage, bile contamination and its consequences are incompletely evaluated. This study aimed to compare outcomes after PD in patients with sterile and those with infected bile. STUDY DESIGN: Seventy-nine consecutive patients underwent PD for periampullary tumor with routine bile culture and antibiotic prophylaxis with cefazolin. The postoperative course of 35 patients with infected bile (group B+) was compared with that of 44 patients with sterile bile (group B-). RESULTS: The distribution of tumors was comparable except for ampullary carcinoma, which was more frequent in group B+ patients (p = 0.001). Interventional biliary endoscopy was performed preoperatively in 80% of patients in group B+ versus 14% in group B- (p < 0.001), including 9 isolated sphincterotomies (20% versus 5%, p < 0.03) and 20 endoprosthesis insertions (57% versus 0%, p < 0.0001). More patients in group B+ were classified as American Society of Anesthesiologists (ASA) 2 (p = 0.04). Operative time and blood loss were similar in both groups. One patient died postoperatively (group B+). Overall morbidity was increased in group B+ (77% versus 59%, p = 0.05). Postoperative infectious complications, all demonstrated bacteriologically, were more frequent in group B+: (65% versus 37%, p = 0.003). In group B+, bile was polybacterial in 54% of patients and isolated microorganisms were resistant to cefazolin in 97%. In patients with infectious complications, the same germ was isolated in bile and another sample in 49%. CONCLUSIONS: In patients undergoing PD, bile infection is related to previous interventional biliary endoscopy in 80% of patients and is associated with an increased rate of postoperative infections. During PD for ampullary carcinoma or after interventional biliary endoscopy, a specific antibioprophylaxis should be evaluated.     

经皮肝穿刺胆道置管引流术前减黄对胰十二指肠切除术后近期并发症的影响

目的 评价经皮肝穿刺胆道置管引流(percutaneous transhepatic biliary drainage,PTBD)作为胰十二指肠切除术前减黄手段对于手术后结果的影响.方法 收集本院2001至2009年115例因胰头癌、胆管远端癌、壶腹癌、十二指肠乳头癌而行胰十二指肠切除患者的临床资料.患者术前采用PTBD作为减黄手段或未进行任何减黄处理,术前或引流前血清胆红素至少＞100 μmol/L且术前无胆管炎表现.115例患者分为PTBD组(42例),早期手术组(73例).对两组间胆瘘、胰瘘、腹腔感染、切口并发症、胃瘫、总并发症、围手术期死亡率、住院时间、住院费用等指标应用PEMS 3.1医学统计软件包进行统计检验.结果 围手术期死亡率PTBD组为2.38％(1例),早期手术组为2.74％(2例),差异无统计学意义.总并发症率PTBD组为54.76％(23例),早期手术组为50.68％(37例),差异无统计学意义.胆瘘、胰瘘、腹腔感染、切口并发症、胃瘫等观察指标也未显示统计学差异.在住院时间和住院费用方面,早期手术组明显优于PTBD组(P＜0.05),差异有统计学意义.结论 PTBD术前减黄对于降低因壶腹周围癌行胰十二指肠切除术术后并发症的作用有限.如果不存在胆管炎或手术需要推迟的原因,术前不需要常规PTBD减黄治疗.     

Influence of bactibilia after preoperative biliary stenting on postoperative infectious complications

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.     

Correlation between preoperative biliary drainage, bile duct contamination, and postoperative outcomes for pancreatic surgery

BACKGROUND: Although previously examined, the potential relationship between preoperative biliary drainage (PBD), intraoperative bile culture (IBC), and postoperative morbidity and mortality rate for pancreatic surgery remains unclear. METHODS: Two hundred twenty patients underwent operation for either benign pancreatic disease or malignant periampullary and pancreatic neoplasms, consisting of pylorus-preserving proximal pancreatoduodenectomy (n = 180), biliary bypass (n = 31), and total pancreatectomy (n = 9). An intraoperative bile specimen was prospectively collected immediately after division of the bile duct and sent for bacteriologic evaluation for both aerobic and anaerobic microorganisms. Morbidity and mortality rates were evaluated. RESULTS: Of 220 patients evaluated, 113 patients (51.4%) had a positive IBC. Factors associated with a positive IBC were age >70 years (odds ratio [OR], 5.9;95% confidence interval, [CI]: 1.6-22.1; P = .007), history of coronary artery disease (OR, 0.08; 95% CI, 0.01-0.5; P = .007), diagnosis of neoplasia (OR, 0.3; 95% CI, 0.1-0.9; P =. 03), and PBD (OR, 0.1; 95% CI, 0.06-0.2; P = .0001). Infectious complications (OR, 1.8; 95% CI, 1-3; P = .03), and wound infection (OR, 2.8; 95% CI,1.4-5.3; P = .002) were greater in patients with positive IBC. CONCLUSIONS: PBD predisposes to a positive IBC. Patients with a positive IBC have a clinically important increased risk of developing both infectious complications and wound infection after pancreatic surgery.     

Technical considerations to maintain a low frequency of postoperative biliary stent-associated infections

Abstract. Background/Purpose: In patients with malignant biliary obstruction, preoperative biliary tract manipulation and stent drainage has been associated with increased infectious complications and mortality. Methods: Between October 1996 and September 2000, 36 patients underwent bilioenteric anastomosis by a single surgeon. Diagnoses included pancreatic and other periampullary cancers (67%), benign obstruction (14%), hilar cholangiocarcinoma (8%), and other malignancies (11%). Preoperative bile duct manipulation had been done in 72%, and a biliary stent had been placed in 58%. Two-thirds of patients underwent major resection and the remainder were treated with internal biliary bypass. All patients had received preoperative bowel cleansing and perioperative antibiotics. Bile ducts were left clamped after incision until anastomotic completion to avoid biliary spillage, and drains were generally not placed. Results: Intraoperative bile cultures were positive in 73%. This was strongly linked to the presence of a stent (P = 0.0004), or prior duct manipulation (P = 0.002). There were 3 postoperative, unrelated deaths in patients after palliative bypass (overall mortality rate, 8.3%). Postoperative infections occurred in 7 patients (19%), of which three were due to a similar organism. There was one biliary leak, no pancreatic leak, and no intraabdominal abscess. Conclusions: Appropriate preoperative antibiotic coverage, preventing intraoperative peritoneal bile contamination through temporary bile duct occlusion, and avoiding routine drain placement, are strongly suggested for patients in whom preoperative biliary manipulation has taken place.

Tinción de Gram intraoperatoria en bilis para la prevención de complicaciones infecciosas en la duodenopancreatectomía

IntroductionInfectious complications play a prominent role in pancreaticoduodenectomy. Their incidence increases in cases with preoperative biliary drainage (PBD), due to the higher risk of bacterobilia. The aim of this study is to evaluate an antibiotherapy protocol based on intraoperative gram staining of bile and its impact on postoperative infectious complications.MethodsA retrospective study analysing the incidence of infectious complications between two groups of 25 consecutive patients undergoing pancreaticoduodenectomy. In group 1, cefazolin prophylaxis was administered to patients without PBD. In cases with PBD a five days antibiotherapy with piperacillin-tazobactam was administered. In group 2, intraoperative gram staining of bile was routinely performed. If no microorganisms were detected, antibiotherapy was limited to cefazolin prophylaxis. If bacterobilia was detected, targeted antibiotherapy was administered for five days.ResultsThe incidence of sepsis and organ/space infection in group 2 was 4% compared to 32% and 24% in group 1 respectively (p<0.05). No differences were observed in the remaining morbimortality variables. The most prevalent microorganisms in bile were Enterococcus spp and Klebsiella spp. In postoperative samples, they only appeared in 4% of cases in group 2 (p<0.05), in favour of S. epidermidis, although they were also prevalent in group 1 (28 and 24% respectively).ConclusionIntraoperative gram staining of bile fluid could be a useful tool to conduct personalised antibiotic therapy in pancreaticoduodenectomy and contribute to the control of infectious complications.     

Pancreaticoduodenectomy for periampullary malignancies: the effect of bile colonization on the postoperative outcome

Objectives The presence of bacteria in the bile of patients undergoing biliary tract surgery has been proposed as associated to an increased incidence of postoperative complications. The present study was designed to determine whether colonization of the bile has an adverse effect in terms of postoperative infectious or noninfectious complications and mortality in a homogenous population of patients suffering from periampullary region malignancies, who all underwent resectional (curative) procedures. Materials and methods Between January 1997 and December 2002, 115 patients (n = 115) suffering from periampullary region malignancies underwent resectional procedures. Fifty-two of the above patients were referred having undergone preoperative internal biliary drainage. During the operation, bile was routinely isolated from the common bile duct and was sent for culture and sensitivity. Based on the bile culture results, the patients were divided in sterile and colonized group and were retrospectively compared in terms of postoperative outcome and mortality. Results Of the 115 bile cultures, 67 were colonized with bacteria and 48 were sterile. Postoperatively, 40 patients developed 35 noninfectious and 21 infectious complications. Univariate analysis did not disclose statistically significant differences in overall, noninfectious or infectious morbidity and mortality between the two groups of patients. Although not statistically significant, a higher incidence (22 vs 10%) of postoperative leaks in the colonized group of patients was noticed. Multiple regression analysis disclosed that colonized bile was independently related to the advanced age, preoperative biliary drainage presence, elevated preoperative serum bilirubin levels and low preoperative serum albumin levels but did not predispose to an increased postoperative morbidity, mortality, or reoperation rate. Conclusion The present study did not conclude in any statistically significant differences in the postoperative infectious and noninfectious morbidity as well as mortality, between colonized and sterile groups of patients who underwent resectional procedures for malignancies of the periampullary region. Although internal biliary drainage introduces microorganisms into the biliary tree, this colonization does not increase the risk of either infectious or noninfectious complications or postoperative death. Thus, the likelihood of bacterobilia should not contraindicate the procedure in selected cases.     

Preoperative biliary colonization/infection caused by multidrug-resistant (MDR) pathogens in patients undergoing major hepatectomy with extrahepatic bile duct resection

Background

The aim of this study was to review the surgical outcomes of patients who underwent major hepatectomy with extrahepatic bile duct resection after preoperative biliary drainage with a particular focus on the impact of preoperative biliary colonization/infection caused by multidrug-resistant pathogens.

Randomized clinical trial of mechanical bowel preparation versus no preparation before elective left-sided colorectal surgery

BACKGROUND: Mechanical bowel preparation (MBP) is performed routinely before colorectal surgery to reduce the risk of postoperative infectious complications. The aim of this randomized clinical trial was to compare the outcome of patients who underwent elective left-sided colorectal surgery with or without MBP. METHODS: Patients scheduled for elective left-sided colorectal resection with primary anastomosis were randomized to preoperative MBP (3 litres of polyethylene glycol) (group 1) or surgery without MBP (group 2). Postoperative abdominal infectious complications and extra-abdominal morbidity were recorded prospectively. RESULTS: One hundred and fifty-three patients were included in the study, 78 in group 1 and 75 in group 2. Demographic, clinical and treatment characteristics did not differ significantly between the two groups. The overall rate of abdominal infectious complications (anastomotic leak, intra-abdominal abscess, peritonitis and wound infection) was 22 per cent in group 1 and 8 per cent in group 2 (P = 0.028). Anastomotic leak occurred in five patients (6 per cent) in group 1 and one (1 per cent) in group 2 (P = 0.210) [corrected] Extra-abdominal morbidity rates were 24 and 11 per cent respectively (P = 0.034). Hospital stay was longer for patients who had MBP (mean(s.d.) 14.9(13.1) versus 9.9(3.8) days; P = 0.024). CONCLUSION: Elective left-sided colorectal surgery without MBP is safe and is associated with reduced postoperative morbidity.

Specific Antibiotic Prophylaxis Based on Bile Cultures Is Required to Prevent Postoperative Infectious Complications in Pancreatoduodenectomy Patients Who Have Undergone Preoperative Biliary Drainage

Background Preoperative biliary drainage (PBD) is associated with bacterial contamination of bile, but the effects of PBD on morbidity after pancreatoduodenectomy remain controversial. The aim of this study was to characterize bile contamination to develop successful specific antibiotic prophylactic strategies for pancreatoduodenectomy. Methods Ninety-one consecutive patients who underwent pancreatoduodenectomy for periampullary tumor were prospectively evaluated. Prophylactic antibiotics were selected based on preoperative bile cultures. Bile cultures and postoperative complications were compared in 46 patients who underwent PBD (drainage group) versus 45 patients who did not (nondrainage group). Results The incidence of positive bile cultures was higher in the drainage group (78%) than in the nondrainage group (36%) (P < 0.001). In the drainage group, positive bile cultures were frequently polymicrobial (61%) and demonstrated resistance to several antibiotics, including cefazolin (83%), cefmetazole (72%), and cefpirome (64%). Overall morbidity (30% and 22%) and infectious morbidity (13% and 11%) did not differ significantly between the drainage and nondrainage groups, respectively. Conclusions PBD had a notable influence on bile microbial contamination, including a higher rate of antibiotic resistance. Therefore, specific antibiotic prophylaxis based on bile culture is required for preventing infectious complications in pancreatoduodenectomy patients who undergo PBD.     

Factors Influencing Readmission After Pancreaticoduodenectomy: A Multi-Institutional Study of 1302 Patients

OBJECTIVE AND BACKGROUND:: Morbidity, mortality, and length of hospital stay after pancreaticoduodenectomy (PD) have significantly decreased over recent decades. Despite this progress, early readmission rates after PD have been reported as high as 50%. Few reports have delineated factors associated with readmission after PD. METHODS:: The medical records of 6 high-volume institutions were reviewed for patients who underwent PD between 2005 and 2010. Data collection included patient characteristics, medical comorbidities, and perioperative factors. Analysis included readmissions up to 90 days after PD. RESULTS:: A total of 1302 patients underwent PD across all institutions. The 30-day and 90-day readmission rates were 15% and 19%, respectively. The most common reasons for 30-day readmission included infectious complications (n = 65) and delayed gastric emptying (n = 29). The most common reasons for readmission after 90 days included wound infections and intra-abdominal abscess (n = 75) and failure to thrive (n = 38). On multivariate analysis, factors associated with higher readmission rates included a preoperative diagnosis of chronic pancreatitis, higher transfusion requirements, and postoperative complications including intra-abdominal abscess and pancreatic fistula (all P < 0.02). Factors not associated with higher readmission rates included advanced age, body mass index, cardiovascular/pulmonary comorbidities, diabetes, steroid use, Whipple type (standard vs pylorus preserving PD), preoperative endobiliary stenting, and vascular reconstruction. CONCLUSIONS:: These multi-institutional data represent a large experience of PD without the biases typically of single center studies. Factors related to infection, nutritional status, and delayed gastric emptying were the most common reasons for readmission after PD. Postoperative complications including pancreatic fistula predicted higher rates of readmission.     

Association of preoperative biliary stenting with increased postoperative infectious complications in proximal cholangiocarcinoma

BACKGROUND: The indications for preoperative biliary stenting in patients with obstructive jaundice are controversial. We evaluated the effect of preoperative biliary stenting on bacterobilia and infectious complications following surgical treatment of proximal cholangiocarcinoma. DESIGN: A retrospective review was performed of all patients undergoing surgical treatment of proximal cholangiocarcinoma. SETTING: A metropolitan cancer surgery service. PATIENTS AND METHODS: Seventy-one patients underwent palliative biliary bypass or curative resection of proximal cholangiocarcinoma from March 1, 1991, to April 1, 1997, and were entered into a prospective database. Forty-one patients underwent preoperative biliary intubation and stent placement. We analyzed patient, nutritional, laboratory, and operating room factors. Statistical evaluation was performed using Student t test and chi2 analysis. MAIN OUTCOME MEASURE: Data were recorded for a history of cholangitis, operative time, amount of blood loss, incidence of intraoperative bacterobilia, proportion of patients with postoperative infectious and noninfectious complications, and length of hospital stay. RESULTS: All patients (n = 14) with a history of preoperative cholangitis had been subjected to previous endoscopic retrograde cholangiopancreatography and/or percutaneous transhepatic biliary drainage. Groups were equivalent for risk for comorbidity, proportion undergoing curative vs palliative procedures, time spent in the operating room, and amount of blood loss. Patients with stents had a significantly lower bilirubin level (P = .005). Patients with stents had a significantly increased risk for bacterobilia (P = .001) and infectious complications (P = .03). Bacterobilia was present in 11 (100%) of 11 patients undergoing endoscopic stenting and in 15 (65%) of 23 patients undergoing percutaneous stenting. There was no increased risk for noninfectious complications, length of hospital stay, or mortality in patients with stents. In 10 (59%) of 17 patients with postoperative infectious complications and positive findings of intraoperative bile culture, the organism was synonymous. CONCLUSIONS: Preoperative biliary stenting in proximal cholangiocarcinoma increases the incidence of contaminated bile and postoperative infectious complications. Endoscopic stents frequently do not relieve jaundice in high biliary obstruction and are rarely indicated, especially in light of their high contamination rate.
