Additional modifications to the Blumgart pancreaticojejunostomy: Results of a propensity score-matched analysis versus Cattel-Warren pancreaticojejunostomy.

BACKGROUND: Postoperative pancreatic fistula continues to occur frequently after pancreatoduodenectomy. METHODS: We have described a modification of the Blumgart pancreaticojejunostomy. The modification of the Blumgart pancreaticojejunostomy was compared to the Cattel-Warren pancreaticojejunostomy in cohorts of patients matched by propensity scores based on factors predictive of clinically relevant postoperative pancreatic fistula, which was the primary endpoint of this study. Based on a noninferiority study design, 95 open pancreatoduodenectomies per group were needed. Feasibility of the modification of the Blumgart pancreaticojejunostomy in robotic pancreatoduodenectomy was also shown. All pancreaticojejunostomies were performed by a single surgeon. RESULTS: Between October 2011 and May 2019, there were 415 pancreatoduodenectomies with either a Cattel-Warren pancreaticojejunostomy (n = 225) or a modification of the Blumgart pancreaticojejunostomy (n = 190). There was 1 grade C postoperative pancreatic fistula in 190 consecutive modification of the Blumgart pancreaticojejunostomies (0.5%). Logistic regression analysis showed that the rate of clinically relevant postoperative pancreatic fistula was not affected by consecutive case number. After exclusion of robotic pancreatoduodenectomies (the Cattel-Warren pancreaticojejunostomy: 82; modification of the Blumgart pancreaticojejunostomy: 66), 267 open pancreatoduodenectomies were left, among which the matching process identified 109 pairs. The modification of the Blumgart pancreaticojejunostomy was shown to be noninferior to the Cattel-Warren pancreaticojejunostomy with respect to clinically relevant postoperative pancreatic fistula (11.9% vs 22.9%; odds ratio: 0.46 [0.21-0.93]; P = .03), grade B postoperative pancreatic fistula (11.9% vs 18.3%; P = .18), and grade C postoperative pancreatic fistula (0 vs 4.6%; P = .05) as well as to all secondary study endpoints. The modification of the Blumgart pancreaticojejunostomy was feasible in 66 robotic pancreatoduodenectomies. In this subgroup with 1 conversion to open surgery (1.5%), a clinically relevant postoperative pancreatic fistula occurred after 9 procedures (13.6%) with no case of grade C postoperative pancreatic fistula and a 90-day mortality of 3%. CONCLUSION: The modification of the Blumgart pancreaticojejunostomy described herein is noninferior to the Cattel-Warren pancreaticojejunostomy in open pancreatoduodenectomy. This technique is also feasible in robotic pancreatoduodenectomy.

The individualized selection of Pancreaticoenteric anastomosis in Pancreaticoduodenectomy.

BACKGROUND: The mortality following pancreaticoduodenectomy has markedly decreased but remains an important challenge for the complexity of operation and technical skills involved. The present study aimed to clarify the impact of individualized pancreaticoenteric anastomosis and management to postoperative pancreatic fistula. METHODS: Data from 529 consecutive pancreaticoduodenectomies were retrospectively analysed from the Hepatobiliary and Pancreatic Surgery Unit I, Peking Cancer Hospital. The pancreaticoenteric anastomosis was determined based on the pancreatic texture and diameter of the main pancreatic duct. The amylase value of the drainage fluid was dynamically monitored postoperatively on days 3, 5 and 7. A low speed intermittent irrigation was performed in selected patients. Intraoperative and postoperative results were collected and compared between the pancreaticogastrostomy (PG) group and pancreaticojejunostomy (PJ) group. RESULTS: From 2010 to 2019, 529 consecutive patients underwent pancreaticoduodenectomy. Pancreaticogastrostomy was performed in 364 patients; pancreaticojejunostomy was performed in 150 patients respectively. The clinically relevant pancreatic fistula (CR-POPF) was 9.8% and mortality was zero. The soft pancreas, diameter of main pancreatic duct≤3 mm, BMI ≥ 25, operation time > 330 min and pancreaticogastrostomy was correlated with postoperative pancreatic fistula significantly. The CR-POPF of PJ was significantly higher than that of PG in soft pancreas patients; the operation time of PJ was shorter than that of PG significantly in hard pancreas patients. Intraoperative blood loss and operation time of PG was less than that of PJ significantly in normal pancreatic duct patients (p < 0.05). CONCLUSIONS: Individualized pancreaticoenteric anastomosis should be determined based on the pancreatic texture and pancreatic duct diameter. The appropriate anastomosis and postoperative management could prevent mortality.

An end-to-side suspender pancreaticojejunostomy: A new invagination pancreaticojejunostomy.

BACKGROUND: Postoperative pancreatic fistula (POPF) is a severe complication of the pancreaticoduodenectomy (PD). Recently, we introduced a method of suspender pancreaticojejunostomy (PJ) to the PD. In this study, we retrospectively analyzed various risk factors for complications after PD. We also introduced and assessed the suspender PJ to demonstrate its advantages. METHODS: Data from 335 patients with various periampullary lesions, who underwent the Whipple procedure (classic Whipple procedure or pylorus-preserving) PD by either traditional end-to-side invagination PJ or suspender PJ, were analyzed. The correlation between either perioperative or postoperative complications and corresponding PD approaches was evaluated by univariate analysis. RESULTS: A total of 147 patients received the traditional end-to-side invagination PJ, and 188 patients were given the suspender PJ. Overall, 51.9% patients had various complications after PD. The mortality rate was 2.4%. The POPF incidence in patients who received the suspender PJ was 5.3%, which was significantly lower than those who received the traditional end-to-side invagination PJ (18.4%) (P < 0.001). Univariate analysis showed that PJ approach and the pancreas texture were significantly associated with the POPF incidence rate (P < 0.01). POPF was a risk factor for both postoperative abdominal cavity infection (OR = 8.34, 95% CI: 3.99-17.42, P < 0.001) and abdominal cavity hemorrhage (OR = 4.86, 95% CI: 1.92-12.33, P = 0.001). CONCLUSIONS: Our study showed that the impact of the pancreas texture was a major risk factor for pancreatic leakage after a PD. The suspender PJ can be easily accomplished and widely applied and can effectively decrease the impact of the pancreas texture on pancreatic fistula after a PD and leads to a lower POPF incidence rate.

Total closure of pancreatic section for end-to-side pancreaticojejunostomy decreases incidence of pancreatic fistula in pancreaticoduodenectomy.

BACKGROUND: Postoperative pancreatic fistula (POPF) is a serious complication and results in prolonged hospitalization and high mortality. The present study aimed to evaluate the safety and effectiveness of total closure of pancreatic section for end-to-side pancreaticojejunostomy in pancreaticoduodenectomy (PD). METHODS: This was a prospective randomized clinical trial comparing the outcomes of PD between patients who underwent total closure of pancreatic section for end-to-side pancreaticojejunostomy (Group A) vs those who underwent conventional pancreaticojejunostomy (Group B). The primary endpoint was the incidence of pancreatic fistula. Secondary endpoints were morbidity and mortality rates. RESULTS: One hundred twenty-three patients were included in this study. The POPF rate was significantly lower in Group A than that in Group B (4.8% vs 16.7%, P<0.05). About 38.3% patients in Group B developed one or more complications; this rate was 14.3% in Group A (P<0.01). The wound/abdominal infection rate was also much higher in Group B than that in Group A (20.0% vs 6.3%, P<0.05). Furthermore, the average hospital stays of the two groups were 18 days in Group A, and 24 days in Group B, respectively (P<0.001). However, there was no difference in the probability of mortality, biliary leakage, delayed gastric emptying, and pulmonary infection between the two groups. CONCLUSION: Total closure of pancreatic section for end-to-side pancreaticojejunostomy is a safe and effective method for pancreaticojejunostomy in PD.

Pancreatic head excavation for tissue diagnosis may reduce unnecessary pancreaticoduodenectomies in the setting of chronic pancreatitis.

BACKGROUND: The necessity to obtain a tissue diagnosis of cancer prior to pancreatic surgery still remains an open debate. In fact, a non-negligible percentage of patients undergoing pancreaticoduodenectomy (PD) for suspected cancer has a benign lesion at final histology. We describe an approach for patients with diagnostic uncertainty between cancer and chronic pancreatitis, with the aim of minimizing the incidence of PD for suspicious malignancy finally diagnosed as benign disease. METHODS: Eighty-eight patients (85.4%) with a clinicoradiological picture highly suggestive for malignancy received formal PD (group 1). Fifteen patients (14.6%) in whom preoperative diagnosis was uncertain between pancreatic cancer and chronic pancreatitis underwent pancreatic head excavation (PHEX) for intraoperative tissue diagnosis (group 2): those diagnosed as having cancer received PD, whereas those with chronic pancreatitis received pancreaticojejunostomy (PJ). RESULTS: No patient received PD for benign disease. All patients in group 1 had adenocarcinoma on final histology. Eight patients of group 2 (53.3%) received PD after intraoperative diagnosis of cancer, whereas 7 (46.7%) received PJ because no malignancy was found at introperative frozen sections. No signs of cancer were encountered in patients receiving PHEX and PJ after a median follow-up of 42 months. Overall survival did not differ between patients receiving PD for cancer in the group 1 and those receiving PD for cancer after PHEX in the group 2 (P=0.509). CONCLUSION: Although the described technique has been used in a very selected group of patients, our results suggest that PHEX for tissue diagnosis may reduce rates of unnecessary PD, when the preoperative diagnosis is uncertain between cancer and chronic pancreatitis.

The Impact of Hepaticojejunostomy Leaks After Pancreatoduodenectomy: a Devastating Source of Morbidity and Mortality.

INTRODUCTION: Hepaticojejunostomy leaks are less frequent than pancreatic leaks after pancreatoduodenectomy, and the current literature suggests comparable outcomes. The purpose of this study was to determine if the hepaticojejunostomy leak adversely affected patient outcomes. METHODS: Consecutive cases of pancreatoduodenectomy (n = 924) were reviewed at a single high-volume institution over an 8-year period (2006-2014). RESULTS: Pancreaticojejunostomy leaks were identified in 217 (23%) patients and hepaticojejunostomy leaks were identified in 24 patients (3%); combined hepaticojejunostomy/pancreaticojejunostomy leaks were identified in 31 patients (3%). Those with hepaticojejunostomy leaks or combined leaks had a significantly increased risk of morbidity when compared to pancreaticojejunostomy leaks or no leak (54 and 58 vs. 34 and 24%, respectively, p < 0.05). The median length of stay was significantly greater for hepaticojejunostomy leaks or combined leaks when compared to pancreatojejunostomy leaks (17 or 14 vs. 9 days, p = 0.001) and those with no leak (17 or 14 vs. 7 days, p = 0.001). Ninety-day mortality for all patients was 3.6%. Hepaticojejunostomy leaks and combined leaks significantly increased 90-day mortality rate (17 and 32%, respectively, p < 0.05). CONCLUSIONS: Hepaticojejunostomy and combined leaks after pancreatoduodenectomy are rarer than pancreaticojejunostomy leaks; these patients are at a significantly increased risk of major morbidity and mortality.

Binding versus Conventional Pancreaticojejunostomy in Preventing Postoperative Pancreatic Fistula: A Systematic Review and Meta-Analysis.

BACKGROUND: The aim of this study was to compare the safety and efficacy of a new technology, binding pancreaticojejunostomy (BPJ), with conventional pancreaticojejunostomy (CPJ) after pancreaticoduodenectomy in preventing postoperative pancreatic fistula (POPF). METHODS: Randomized controlled trials and observational studies were retrieved from literature searches. Pooled OR with 95% CI for dichotomous variables and weighted mean difference with 95% CI for continuous variables were calculated. Fixed-effect and random-effect models as well as subgroup analysis were used for sensitivity analysis. RESULTS: No statistically significant differences were found in the incidence of POPF, delayed gastric emptying, postpancreatectomy hemorrhage, reoperation, morbidity, mortality, operation time, intraoperative blood loss, blood transfusion, and hospital stay between 2 groups. However, the total costs of hospitalization and ordinary stay were higher in BPJ group (€10,513 ± €6,536 vs. €8,238 ± €4,687, p = 0.002; €7,946 ± €5,023 vs. €5,700 ± €2,902, p = 0.015, respectively). CONCLUSIONS: Our study showed BPJ was as safe as CPJ. However, no significant superiority was found in BPJ group regarding the incidence of POPF. The total costs of hospital stay were higher for patients undergoing BPJ. Surgeons can prefer to perform the digestive tract reconstruction of their choice.

Three hundred and sixty-eight consecutive pancreaticoduodenectomies with zero mortality.

BACKGROUND: Only a limited number of reports have documented zero mortality in consecutive pancreaticoduodenectomy series. The aim of this study is to review and verify our management aiming to eliminate mortality after pancreaticoduodenectomy. METHODS: Three hundred and sixty-eight consecutive patients undergoing pancreaticoduodenectomy between 2002 and 2015 were retrospectively reviewed. During this period, in order to enhance the safety of pancreaticoduodenectomy, we have used a consistent strategy consisting of early ligation of the inferior pancreatoduodenal artery, mucosal sutureless pancreaticojejunostomy combined with external pancreatic duct stenting, conditional two-stage pancreaticojejunostomy, jejunal decompression using tube jejunostomy, application of an omental flap to cover the stump of the gastroduodenal artery, and careful postoperative drain management. RESULTS: Major postoperative complications (Clavien-Dindo grade ≥ IIIa) occurred in 20 patients (5%). Grade A/B/C pancreatic fistula was observed in 49/29/4 patients (13%/8%/1%), respectively. Reoperation and readmission was necessary in five and four patients (1% and 1%), respectively. There was no in-hospital or 90-day mortality. CONCLUSIONS: To achieve zero mortality in pancreaticoduodenectomy, it is crucial to incorporate various strategies to minimize the degree of surgical invasiveness and the damage caused by pancreatic fistula with a meticulous approach to perioperative management.

[The outcomes of different pancreatodigestive anastomoses in pancreatoduodenectomy].

AIM: To compare early results after pancreaticoduodenectomy depending on variant of pancreatico-digestive anastomosis. MATERIAL AND METHODS: It was analyzed early results of 207 pancreaticoduodenectomies for cancer which were performed for the period 2010-2014. Pancreatointestinal and pancreatogastric anastomoses were applied in 165 and 42 patients respectively. RESULTS: Complications were observed in 73 (44.2%) and 18 (38.3%) patients after pancreatointestinal and pancreatogastric anastomoses respectively. Six patients died after pancreatointestinal anastomosis. At the same time there were no deaths in the group of pancreatogastric anastomosis. Differences were significant. Postoperative hospital-stay was similar in both groups.

Comparison of Modified Blumgart pancreaticojejunostomy and pancreaticogastrostomy after pancreaticoduodenectomy.

BACKGROUND: The aim of this study was to compare perioperative outcomes after Blumgart pancreaticojejunostomy (PJ) and pancreaticogastrostomy (PG) for pancreatic-enteric reconstruction following pancreaticoduodenectomy. METHODS: Data of patients undergoing Blumgart PJ and PG were retrieved from prospectively-collected database. Matched patients in each surgical groups were included based on the Callery risk scoring system for clinically relevant postoperative pancreatic fistula (CR-POPF) (grades B and C). Surgical parameters and risks were compared between these two groups. RESULTS: A total of 206 patients undergoing PD were included. Blumgart PJ was associated with shorter postoperative hospital stay (median (range) 25 (10-99) vs. 27 (10-97) days, P = 0.022). There was no surgical mortality in the Blumgart PJ group, but a 4.9% perioperative mortality in the PG, P = 0.030. The CR-POPF by Blumgrt PG is significantly lower than that by PG for overall patients (7% vs. 20%, P = 0.007), especially for those in intermediate fistula risk zone (6% vs. 21%, P =0.048) and high fistula risk zone (14% vs. 47%, P=0.038). CONCLUSIONS: Blumgart PJ is superior to PG in terms of pancreatic leakage and surgical mortality. Blumgart PJ can be recommended for pancreatic reconstruction after PD for all pancreatic remnant subtypes.

Efficacy of non-stented pancreaticojejunostomy demonstrated in the hard pancreas.

BACKGROUND/AIMS: The aim of this study was to compare hard and soft pancreas for short-term complications of pancreaticoduodenectomy performed with a duct-to-mucosa anastomosis of pancreaticojejunostomy without a stenting tube. METHODOLOGY: We investigated 156 patients with pancreaticojejunostomy who were classified into two groups of hard pancreas (group A: 79) and soft pancreas (group B: 77). Outcomes, including complications and operative procedures, are reported. RESULTS: There were no differences between groups A and B for median age, gender, performance status. Biliary drainage ratio and disease classification of Groups A and B were statistically different. In preoperative status, there were no differences in Body Mass Index, total bilirubin, albumin, hemoglobin, creatinine, and PFD. Group B had lower HbA1C levels than group A. In operative procedures, there were no differences in operative times and blood loss, but group B had longer postoperative hospital days than group A. On operative results, there were no differences in mortality, delayed gastric emptying, biliary fistula, hemorrhage, cholangitis, lymph leakage, and others. There were significant differences between groups A and B in morbidity (12.7% vs. 35.1%), pancreatic fistula (0% vs. 9.1%), intra-abdominal abscess (1.3% vs. 9.1%). CONCLUSION: Efficacy of pancreaticojejunostomy without a stenting tube for hard pancreas was demonstrated.

Quality standards in 480 pancreatic resections: a prospective observational study.

Pancreatic resection is a standard procedure for the treatment of periampullary tumors. Morbidity and mortality are high, and quality standards are scarce in our setting. International classifications of complications (Clavien-Dindo) and those specific for pancreatectomies (ISGPS) allow adequate case comparisons. The goals of our work are to describe the morbidity and mortality of 480 pancreatectomies using the international classifications ISGPS and Clavien-Dindo to help establish a quality standard in our setting and to compare the results of CPD with reconstruction by pancreaticogastrostomy (1,55) versus 177 pancreaticojejunostomy). We report 480 resections including 337 duodenopancreatectomies, 116 distal pancreatectomies, 11 total pancreatectomies, 10 central pancreatectomies, and 6 enucleations. Results for duodenopancreatectomy include: 62 % morbidity (Clavien > or = III 25.9 %), 12.3 % reinterventions, and 3.3 % overall mortality. For reconstruction by pancreaticojejunostomy: 71.2 % morbidity (Clavien > or = III 34.4 %), 17.5 % reinterventions, and 3.3 % mortality. For reconstruction by pancreaticogastrostomy: 51 % morbidity (Clavien > or = III 15.4%), 6.4 % reinterventions, and 3.2 % mortality. Differences are significant except for mortality. We conclude that our series meets quality criteria as compared to other groups. Reconstruction with pancreaticogastrostomy significantly reduces complication number and severity, as well as pancreatic fistula and reintervention rates.

The effect of modified pancreaticojejunostomy for reducing the pancreatic fistula after pancreaticoduodenectomy.

BACKGROUND/AIMS: Pancreatic fistula (PF) has traditionally been a source of significant morbidity and mortality after pancreaticoduodenectomy (PD). External drainage of pancreatic duct with stent and Blumgart anastomosis had reduced PF after PD in some studies. We applied compounding described two methods for pancreaticojejunostomy (PJ) during PD, and investigated the effectiveness of this modified PJ technique to prevent PF. METHODOLOGY: Between March 2002, and March 2013, 90 patients who underwent PD were enrolled. The patients were divided into 2 groups according to pancreatienterostomy method. Group 1 contain patients who did not undergo modified PJ (n=70) compared with group 2 (n=20) those who did undergo the modified PJ technique. We compared clinical data between two groups. RESULTS: No differences were noted in the demographics and operation-related factors, between the 2 groups. A PF occurred in 38 of 70 patients in group 1 (54.3%) and in 2 of 20 in group 2 (10.0%). Group 2 had a significantly lower incidence of PF (P=.0016), and these fistulas were classified as being grade A using the International Study Group on Pancreatic Fistula Definition. Mortality in group 1 was 10.0% and no mortality in group 2. CONCLUSIONS: External drainage with Blumgart method of PJ showed reducing high grade PF after PD.

[The method of pancreaticojejunostomy in pancreaticoduodenectomy].

The method of pancreaticojejunostomy in pancreaticoduodenectomy was applied in 20 patients. The technique is based on the first row of through P-shaped sutures in the sequence of jejunum-pancreas-jejunum. This method excludes thread pressure on pancreatic tissue. The technique may be used in any pancreatic texture. Pancreaticojejunostomy failure was observed in 2 patients (10%). The complication was not determined by pancreatic anastomotic technique in 1 case. There were 2 deaths (10%). The causes of lethal outcomes were not determined by peculiarities of pancreaticojejunostomy performing. The obtained results show good preventive properties of proposed method relatively pancreaticojejunostomy failure and postoperative pancreatitis.

Pancreaticogastrostomy versus pancreaticojejunostomy after pancreaticoduodenectomy: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The aim of this systematic review was to compare postoperative outcomes between pancreaticogastrostomy and pancreaticojejunostomy after pancreaticoduodenectomy. METHODS: Six databases were systematically reviewed to identify randomized controlled trials comparing pancreaticogastrostomy and pancreaticojejunostomy. Studies reporting postoperative complications, reoperations, and mortality were included (PROSPERO registration number CRD42013005383). RESULTS: The search provided a total of 1,646 references. Seven studies were selected including 1,121 patients, 562 in the pancreaticogastrostomy group and 559 in the pancreaticojejunostomy group. Overall incidence of pancreatic fistula and the incidence of more severe fistulas (grade B/C) were lower in the pancreaticogastrostomy group (relative risk 0.67; 95% confidence interval (CI) 0.52 to 0.86; p = 0.002 and relative risk 0.61; 95 % CI 0.40 to 0.93; p = 0.02). Abdominal collections were more frequent in the pancreaticojejunostomy group. However, pancreaticogastrostomy was associated with an increased risk of postoperative intraluminal hemorrhage, and there were no differences in overall morbidity, reoperations, or mortality. CONCLUSIONS: In this systematic review and meta-analysis, a reduction in the incidence of postoperative pancreatic fistula in the pancreaticogastrostomy group was observed. Although this evidence comes from randomized trials, pancreaticogastrostomy cannot be considered superior to pancreaticojejunostomy due to the presence of clinical heterogeneity among studies and the absence of differences in overall morbidity, reoperations, and mortality.

Pancreaticogastrostomy versus pancreaticojejunostomy.

BACKGROUND: It has long been debated whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is the better choice for reconstruction after pancreaticoduodenectomy. The purpose of this study is to evaluate the two techniques. METHODS: Randomized controlled trials (RCTs) comparing PG with PJ published from January 1995 to January 2014 were searched electronically using PubMed, Medline, and Cochrane Library. Published data of these RCTs were analyzed using either fixed-effects model or random-effects model. RESULTS: Seven RCTs were included in this meta-analysis, with a total of 1121 patients (562 in PG, 559 in PJ). The incidence of postoperative pancreatic fistula and intra-abdominal fluid collection were significantly lower in PG than in PJ (respectively: odds ratio = 0.53 [0.37, 0.74], P < 0.001; odds ratio = 0.48 [0.30, 0.76], P < 0.01), no significant difference could be found for delayed gastric emptying, hemorrhage, morbidity, reoperation rate, and mortality. CONCLUSIONS: The evidence from RCTs suggests that PG technique is associated with a lower rate of postoperative pancreatic fistula and intra-abdominal fluid collection than PJ.

Isolated Roux loop pancreaticojejunostomy versus pancreaticogastrostomy after pancreaticoduodenectomy: a prospective randomized study.

OBJECTIVES: The optimal strategy for the reconstruction of the pancreas following pancreaticoduodenectomy (PD) is still debated. The aim of this study was to compare the outcomes of isolated Roux loop pancreaticojejunostomy (IRPJ) with those of pancreaticogastrostomy (PG) after PD. METHODS: Consecutive patients submitted to PD were randomized to either method of reconstruction. The primary outcome measure was the rate of postoperative pancreatic fistula (POPF). Secondary outcomes included operative time, day to resumption of oral feeding, postoperative morbidity and mortality, and exocrine and endocrine pancreatic functions. RESULTS: Ninety patients treated by PD were included in the study. The median total operative time was significantly longer in the IRPJ group (320 min versus 300 min; P = 0.047). Postoperative pancreatic fistula developed in nine of 45 patients in the IRPJ group and 10 of 45 patients in the PG group (P = 0.796). Seven IRPJ patients and four PG patients had POPF of type B or C (P = 0.710). Time to resumption of oral feeding was shorter in the IRPJ group (P = 0.03). Steatorrhea at 1 year was reported in nine of 42 IRPJ patients and 18 of 41 PG patients (P = 0.029). Albumin levels at 1 year were 3.6 g/dl in the IRPJ group and 3.3 g/dl in the PG group (P = 0.001). CONCLUSIONS: Isolated Roux loop PJ was not associated with a lower rate of POPF, but was associated with a decrease in the incidence of postoperative steatorrhea. The technique allowed for early oral feeding and the maintenance of oral feeding even if POPF developed.

Postpancreatectomy hemorrhage--incidence, treatment, and risk factors in over 1,000 pancreatic resections.

BACKGROUND: Postpancreatectomy hemorrhage is a rare but often severe complication after pancreatic resection. The aim of this retrospective study was to define incidence and risk factors of postpancreatectomy hemorrhage and to evaluate treatment options and outcome. PATIENTS AND METHODS: Clinical data was extracted from a prospectively maintained database. Descriptive statistics, univariate and multivariate risk factor analysis by binary logistic regression were performed with SPSS software at a significance level of p = 0.05. RESULTS: N = 1,082 patients with pancreatic resections between 1994 and 2012 were included. Interventional angiography was successful in about half of extraluminal bleeding. A total of 78 patients (7.2 %) had postpancreatectomy hemorrhage (PPH), and 29 (2.7 %) were grade C PPH. Multivariate modeling disclosed a learning effect, age, BMI, male sex, intraoperative transfusion, portal venous and multivisceral resection, pancreatic fistula and preoperative biliary drainage as independent predictors of severe postpancreatectomy hemorrhage. High-risk histopathology, age, transfusion, pancreatic fistula, postpancreatectomy hemorrhage and pancreatojejunostomy in pancreatoduodenectomies were independent predictors of mortality. CONCLUSIONS: Our study identifies clinically relevant risk factors for postpancreatectomy hemorrhage and mortality. Interventional treatment of extraluminal hemorrhage is successful in about half of the cases and if unsuccessful constitutes a valuable adjunct to operative hemostasis. Based on our observations, we propose a treatment scheme for PPH. Risk factor analysis suggests appropriate patient selection especially for extended resections and pancreatogastrostomy for reconstruction in pancreatoduodenectomy.

Parenchyma-Sparing Pancreatic Resections: With or Without a Pancreaticojejunostomy?

BACKGROUND/AIM: Parenchyma-sparing pancreatic resections are used in low-grade malignant tumors, but result in a high incidence of pancreatic fistula. Pancreaticojejunostomy to the site of resection might decrease the risk of pancreatic fistula. The purpose of this study was to evaluate the influence of pancreaticojejunostomy on the outcomes of parenchyma-sparing resections. METHODOLOGY: The study group consisted of 21 patients (M/F = 4:17, mean age = 47 years). Local tumor resection with a pancreaticojejunostomy was performed in 11 patients and enucleation in 10 patients. Both groups were compared retrospectively with regard to perioperative variables. RESULTS: The operative time was significantly shorter in the enucleation group (median 180 min vs. 222 min, P = 0.005). The overall surgical morbidity was similar in both groups (81% vs. 70%, P = 0.64). The rate of clinically significant pancreatic fistula (64% vs. 40%, P = 0.39), hemorrhagic complications (27% vs. 10%, P = 0.59) and wound infection (18% vs. 40%, P = 0.36) were comparable in both groups. One patient died after central pancreatectomy. There were no new-onset cases of diabetes mellitus postoperatively. CONCLUSIONS: Local resection combined with pancreaticojejunostomy is an option to avoid extensive resection of the pancreatic parenchyma, but is still associated with a high incidence of pancreatic fistula which is comparable to that after enucleation.
