Postoperative pancreatic fistulas after pancreaticoduodenectomy for malignancy: A Northeast Indian tertiary cancer center study. JGH OPEN 2021; 5:1009-1014. [PMID: 34584968 PMCID: PMC8454483 DOI: 10.1002/jgh3.12609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Revised: 06/22/2021] [Accepted: 06/25/2021] [Indexed: 12/04/2022]
Abstract
Background and Aim Postoperative pancreatic fistula (POPF) is an important cause of major morbidity and mortality after pancreaticoduodenectomy. We intend to estimate the incidence and study the risk factors and outcomes of patients who developed this dreaded complication. Methods This is a retrospective observational study. We included all patients who underwent pancreaticoduodenectomy at a specialized surgical unit of a single tertiary care cancer center in Northeast India. The period of study was from 23 April 2012 to 27 December 2019. The 2016 update on the definition of POPF by the International Study Group for Pancreatic Fistula was used to define the complication. Chi‐square test and Fischer's exact test were applied to categorical variables. t‐test was used to quantify mean difference among continuous variables. P value <0.05 was considered statistically significant at 95% confidence interval. Results A total of 59 patients underwent pancreaticoduodenectomy during the study period with almost equal distribution among males and females (29 and 30 patients respectively). The mean age of the patients was 54.0 years (range 20–72). Grade A, B, and C pancreatic fistulas were seen in five (8.5%), three (5.1%), and two (3.4%) patients, respectively. Preoperative hyperbilirubinemia, pancreatic duct size ≤3 mm, hypoalbuminemia, preoperative biliary decompression, and prolonged duration of surgery were identified as risk factors for POPF. POPF also resulted in increased 90‐day mortality (20%). Conclusion POPF remains a potentially life‐threatening complication of pancreaticoduodenectomies. The knowledge and management of modifiable risk factors for this condition may help in mitigating this problem.

Reduction in post-operative pancreatic fistula with polyethylene glycol and recombinant human albumin sealant following stapled distal pancreatectomy. ANZ J Surg 2021; 91:2459-2465. [PMID: 34514684 DOI: 10.1111/ans.17181] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2021] [Revised: 08/11/2021] [Accepted: 08/20/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) remains a significant cause of morbidity in patients undergoing distal pancreatectomy (DP). The use of polyethylene glycol (PEG) and recombinant human albumin sealant gel applied to the transected pancreatic margin in DP may reduce POPF rates and was assessed. METHODS A retrospective single centre cohort study of patient undergoing DP at an Australian high volume tertiary institution between January 2015 and January 2021. Rates of POPF in patients undergoing stapled pancreatic transection with PEG sealant were compared to other methods. RESULTS A total of 54 cases were identified for analysis, with 16 undergoing stapled DP combined with staple line application of PEG (PEG group). Most patients in the control group had stapled DP 92% (35 of 38), with 47% (18 of 38) combined with a reinforcing buttress, with or without the use other glue types. Overall, 28 of 54 (52%) developed a POPF, with a significantly lower rate in the PEG group (3 of 16 vs. 25 of 38 in the Control group; p = 0.003). Clinically significant Grade B/C POPF was lower in the PEG group (0 of 16 vs. 9 of 28 in the Control group; p = 0.045), and patients in the PEG group had a shorter median (range) length of hospital stay (6 [4-14] days vs. 10 [6-41] days p = 0.04). CONCLUSION Stapled DP with the application of PEG and recombinant human albumin sealant to the transection line appears to be associated with a lower rate of clinically significant POPF.

Abstract
Surgery remains the only curative treatment of pancreatic neuroendocrine neoplasms (pNEN). Here, we report the outcome after surgery for non-functional pNEN at a European Neuroendocrine Tumor Society (ENETS) center in Germany between 2000 and 2019; cases were analyzed for surgical (Clavien–Dindo classification; CDc) and oncological outcomes. Forty-nine patients (tumor grading G1 n = 25, G2 n = 22, G3 n = 2), with a median age of 56 years, were included. Severe complications (CDc ≥ grade 3b) occurred in 11 patients (22.4%) and type B/C pancreatic fistulas (POPFs) occurred in 5 patients (10.2%); in-hospital mortality was 2% (n = 1). Six of seven patients with tumor recurrence (14.3%) had G2 tumors in the pancreatic body/tail. The median survival was 5.7 years (68 months; [1–228 months]). Neither the occurrence (p = 0.683) nor the severity of complications had an influence on the relapse behavior (p = 0.086). This also applied for a POPF (≥B, p = 0.609). G2 pNEN patients (n = 22) with and without tumor recurrence had similar median tumor sizes (4 cm and 3.9 cm, respectively). Five of the six relapsed G2 patients (83.3%) had tumor-positive lymph nodes (N+); all G2 pNEN patients with recurrence had initially been treated with distal pancreatic resection. Pancreatic resections for pNEN are safe but associated with relevant postoperative morbidity. Future studies are needed to evaluate suitable resection strategies for G2 pNEN.

Abstract
BACKGROUND Drain management is important for the detection and treatment of clinically relevant postoperative pancreatic fistula (CR-POPF). We previously established the triple-checked criteria for drain removal: drain fluid amylase (DFA) <5000 U/L on postoperative day (POD) 1 and DFA <3000 U/L on POD 3, or C-reactive protein <15 mg/dL on POD 3. This study aimed to validate the efficacy of the triple-checked criteria. METHODS In this study, 681 patients who underwent pancreatectomy were included. Drains were removed according to our previous criteria (sequentially checked criteria: DFA <5000 U/L on POD 1 and DFA <3000 U/L on POD 3) from 2012 to 2016 (control group) and the triple-checked criteria from 2017 to 2019 (intervention group). RESULTS The control group included 406 patients, and the intervention group included 275 patients. Significantly more patients (n = 237, 86.2%) met the triple-checked criteria in the intervention group, relative to the sequentially checked criteria for early drain removal policy (n = 309, 76.1%; P = .001). Sensitivity, accuracy, and negative predictive value were significantly higher in the intervention group than in the control group (P < .001). The incidence of CR-POPF was not significantly different (11.1% vs 13.8%, P = .285). CONCLUSIONS The triple-checked criteria contributed to effective drain removal after pancreatectomy without increasing CR-POPF.

Abstract
PURPOSE Multiple attempts have been made to manage the pancreatic stump and the pancreatic duct in order to reduce the rate of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD), however radiofrequency-based technologies could help to achieve this goal. Previous encouraging clinical and experimental results support the use of endoluminal thermal ablation (ETHA) of the main pancreatic duct to reduce pancreatic exocrine secretion and hence POPF. We here describe our initial clinical experience with ETHA of the main pancreatic duct in two cases at high risk of POPF. METHODS Two cases underwent PD for malignancy with a high risk of POPF (adenocarcinoma, obese patients, surgical difficulties with heavy intraoperative blood loss, soft pancreas or walled-off pancreatitis and a tight small pancreatic main duct). In both cases, ETHA of the main pancreatic duct was conducted intraoperatively just before Blumgart-type pancreatic-jejunal anastomosis using a ClosureFast catheter (Medtronic, Mansfield, MA, USA) normally used for varicose vein treatment (therefore an off-label use). RESULTS Although a clear radiological POPF was detected in the second case, the clinical postoperative course in both cases was uneventful. Little pancreatic fluid collected in the abdominal drainage with low levels of amylase enzyme, confirming low exocrine pancreatic function. No other procedure-related complications were detected. CONCLUSION Endoluminal thermal ablation of the main pancreatic duct may be a feasible and safe technique to reduce the adverse effects of POPF after PD.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) remains a severe and challenging complication of pancreaticoduodenectomy (PD). This study aimed to establish a novel postoperative nomogram-based diagnostic model for the early detection of CR-POPF in patients subjected to PD. METHODS Consecutive patients who underwent PD in Zhongshan Hospital, Fudan University from December 2018 to October 2020 were retrospectively enrolled. Univariate and multivariate logistic regression analyses were performed to identify independent risk factors for CR-POPF. Then, a novel predictive nomogram was established accordingly. RESULTS Among the consecutive 176 patients who underwent PD, 37 (21.1%) patients developed CR-POPF. Through univariate and multivariate analyses, the drain amylase (P = 0.002), serum creatinine (P = 0.009), and serum C reactive protein (P = 0.045) at postoperative day 1 (POD1) as well as the neutrophil count (P = 0.025) and temperature (P = 0.025) at POD3 were identified as independent risk factors for CR-POPF. Based on this, a novel predictive nomogram containing these factors was constructed to predict the probability of CR-POPF after PD. The formulated nomogram showed better performance to detect CR-POPF after PD with a sensitivity of 0.784, specificity of 0.770, positive predictive value of 0.475, and negative predictive value of 0.930 when compared to other predictors. In addition, the predictive value of the nomogram was assessed by a concordance index of 0.814 (95% CI, 0.736-0.892), which was significantly higher than indicators alone. This was further validated and depicted by decision curve analysis and clinical impact curve. CONCLUSION This study established a diagnostic nomogram of postoperative objective parameters that can predict the development of CR-POPF after PD with a good discriminative ability and predictive accuracy.

Detrimental effect of intraoperative hypothermia on pancreatic fistula after pancreaticoduodenectomy: A single-centre retrospective study. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2021; 28:983-992.

Abstract
BACKGROUND Although perioperative hypothermia was found to be associated with gastrointestinal anastomotic leakage in preclinical studies, its association with postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy was never evaluated. We investigated the association between intraoperative hypothermia and clinically relevant (CR)-POPF following pancreaticoduodenectomy. METHODS We retrospectively reviewed 2163 consecutive patients who underwent pancreaticoduodenectomy during 2007-2019. Based on intraoperative time-weighted average core temperature, patients were grouped into normothermia (36.0-37.5°C), mild hypothermia (35.0-<36.0°C), and severe hypothermia (<35°C). We conducted multivariable logistic regression analysis for CR-POPF, a propensity score analysis using inverse probability of treatment weighting (IPTW) to adjust the baseline differences between the three groups, followed by multivariable logistic regression with IPTW for CR-POPF. RESULTS Among the 2008 patients analysed, 1118 (55.7%) and 120 (6.0%) had mild and severe hypothermia, respectively, and 14.2% overall incidence of CR-POPF. Severe intraoperative hypothermia was significantly associated with CR-POPF before and after IPTW (before: odds ratio [OR] 1.79, 95% confidence interval [CI]: 1.03-3.09, P = .038; after: OR 2.48, 95% CI: 1.28-4.81, P = .007); however, mild hypothermia had no significant associations. CONCLUSION Severe intraoperative hypothermia is significantly associated with the occurrence of CR-POPF following pancreaticoduodenectomy, suggesting that hypothermia is deleterious on pancreaticojejunal anastomotic healing.

Abstract
Backgound: This study aimed to determine the usefulness of the Controlling Nutritional Status (CONUT) scorescore for predicting postoperative pancreatic fistula (POPF). PATIENTS AND METHODS Data from 108 consecutive pancreaticoduodenectomy cases performed at the Surgery Department of Iwakuni Clinical Center, from April 2008 to May 2018, were included. Preoperative patient data and postoperative complication data were collected. RESULTS Of the 108 patients (male=65; female=43; mean age=70 years), 41 (37.9%) had indication for pancreaticoduodenectomy due to pancreatic carcinoma. Grade B or higher POPF was diagnosed in 32 patients (29.6%). In the multivariate analysis, body mass index ≥22 kg/m2 [odds ratio (OR)=5.24; p=0.005], CONUT score ≥4 (OR=3.28; p=0.042), non-pancreatic carcinoma (OR=47.17; p=0.001), and a low computed tomographic contrast attenuation value (late/early ratio) (OR=4.39; p=0.029) were independent risk factors for POPF. CONCLUSION Patients with high CONUT score are at high risk for POPF. Preoperative nutritional intervention such as immunonutrition might help reduce the POPF risk in these patients.

Abstract
Post-operative pancreatic fistula (POPF) remains the most common complication after distal pancreatectomy (DP). In this retrospective study, we reviewed the data from patients who underwent DP between 2008 and 2019 in our institute to determine whether the late phase/early phase ratio (L/E ratio) by preoperative computed tomography (CT) scan in the pancreas could predict POPF occurrence after DP. We examined the relationship between preoperative or intraoperative factors and the occurrence of POPF after DP using statistical methods in 23 males and 21 females with a mean age of 73. The mean L/E ratio was significantly lower in the POPF group than the non-POPF group (p=0.035). The L/E ratio had moderate diagnostic accuracy, with a calculated optimal cutoff value of 0.77. In univariate analysis, a significant association was noted between POPF and stump thickness ≥ 16.9, body mass index ≥ 27.5, and L/E ratio ≤ 0.77. In the multivariate analysis, the L/E ratio (odds ratio, 5.96; p=0.036) was an independent risk factor for POPF. Our findings suggest that the pancreatic L/E ratio may predict the occurrence of POPF after DP. This measure may be useful in preoperative risk stratification, patient counseling, and perioperative patient management, improving clinical outcomes after DP.

Abstract
ABSTRACT Laparoscopic pancreaticoduodenectomy (LPD) is widely used as a treatment for periampullary tumors and pancreatic head tumors. However, postoperative pancreatic fistula (POPF), which significantly affects mortality and length of hospital stay of patients, remains one of the most common and serious complications following LPD. Though numerous technical modifications for pancreaticojejunostomy (PJ) have been proposed, POPF is still the "Achilles heel" of LPD.To reduce POPF rate and other postoperative complications following LPD by exploring the best approach to manage with the pancreatic remnant, a novel duct-to-mucosa anastomosis technique named Double Layer Running Suture (Double R) for the PJ was established. During 2018 and 2020, a totally 35 patients who underwent LPD with Double R were included, data on the total operative time, PJ duration, estimated blood loss, recovery of bowel function, postoperative complications, and length of hospital stay were collected and analyzed.The average duration of surgery was (380 ± 69) minutes. The mean time for performing PJ was (34 ± 5) minutes. The average estimated blood loss was (180 ± 155) mL. The overall POPF rate was 8.6% (3/35), including 8.6% (3/35) for the biochemical leak, 0% (0/35) for Grade B, and 0% (0/35) for Grade C. No patient suffered from biliary fistula, post-pancreatectomy hemorrhage, and intra-abdominal infection, the 30-day mortality was 0%.Double R anastomosis is potentially a safe, reliable, and rapid anastomosis with a low rate of POPF and post-pancreatectomy hemorrhage. It provides surgeons more options when performing LPD. However, its safety and effectiveness should be verified further by a larger prospective multicenter study.

Abstract
Background Although the association between an increase in anastomotic leakage (AL) and non-steroidal anti-inflammatory drugs (NSAIDs) has been reported in gastrointestinal surgeries, this issue has rarely been addressed for pancreaticoduodenectomy (PD). We aimed to investigate the association between postoperative NSAIDs administration and clinically relevant AL (CR-AL) following PD. Method We retrospectively evaluated 2,163 consecutive patients who underwent PD between 2007 and 2019. The patients were divided into two groups: patients who received and did not receive NSAIDs by postoperative day (POD) 5. We conducted a propensity score analysis using inverse probability of treatment weighting (IPTW) to adjust the baseline differences between both groups. We compared the occurrence of CR-AL and other postoperative outcomes before and after IPTW. Further, we used the multivariable binary logistic regression method for a sensitivity analysis for CR-AL. Results A total of 2,136 patients were included in the analysis. Of these, 222 (10.4%) received NSAIDs by POD 5. The overall occurrence rate of CR-AL was 14.9%. After IPTW, postoperative NSAIDs were significantly associated with CR-AL (odds ratio [OR] 1.24, 95% confidence interval [CI], 1.05-1.47; P=0.012), prolonged postoperative hospitalization (OR 1.31, 95% CI 1.14-1.50, P<0.001), and unplanned readmission within 30 days postoperatively (OR 1.48, 95% CI 1.15-1.91, P=0.002). However, this association was not consistent in the sensitivity analysis. Conclusion Postoperative NSAIDs use was significantly associated with an increase in CR-AL incidence following PD. However, sensitivity analysis failed to show its association, which precludes a firm conclusion of its detrimental effect.

Rate of Post-Operative Pancreatic Fistula after Robotic-Assisted Pancreaticoduodenectomy with Pancreato-Jejunostomy versus Pancreato-Gastrostomy: A Retrospective Case Matched Comparative Study. J Clin Med 2021; 10:jcm10102181. [PMID: 34070025 DOI: 10.3390/jcm10102181] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Revised: 05/08/2021] [Accepted: 05/14/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Different techniques of pancreatic anastomosis have been described, with inconclusive results in terms of pancreatic fistula reduction. Studies comparing robotic pancreaticogastrostomy (PG) and pancreaticojejunostomy (PJ) are scarcely reported. METHODS The present study analyzes the outcomes of two case-matched groups of patients who underwent PG (n = 20) or PJ (n = 40) after pancreaticoduodenectomy. The primary aim was to compare the rate of post-operative pancreatic fistula. RESULTS Operative time (375 vs. 315 min, p = 0.34), estimated blood loss (270 vs. 295 mL, p = 0.44), and rate of clinically relevant post-operative pancreatic fistula (12.5% vs. 10%, p = 0.82) were similar between the two groups. PJ was associated with a higher rate of intra-abdominal collections (7.5% vs. 0%, p = 0.002), but lower post-pancreatectomy hemorrhage (2.5% vs. 10%, p = 0.003). PG was associated with a lower rate of post-operative pancreatic fistula (POPF) (33.3% vs. 50%, p = 0.003) in the high-risk group of patients. CONCLUSIONS The outcomes of post-operative pancreatic fistula are comparable between the two reconstruction techniques. PG may have a lower incidence of POPF in patients with high-risk of pancreatic fistula.

Abstract
BACKGROUND Bacterobilia is associated with postoperative morbidity after pancreaticoduodenectomy (PD), mostly due to infectious complications. The aim of this study was to investigate the prevalence of bacteria species isolated from intraoperative biliary cultures, and related complications after PD. METHODS An ANOVA test was used to assess the prevalence of isolated bacterial species and postoperative complications. The odds ratio was computed to evaluate the association between biliary cultures and each complication, Endoscopic Retrograde CholangioPancreatography (ERCP) and each complication, ERCP and biliary cultures, Delayed Gastric Emptying (DGE) and Postoperative Pancreatic Fistula (POPF). RESULTS Positive biliary cultures were found in 162/244 (66%) PDs. Different prevalences of polymicrobial biliary culture were detected in patients with postoperative complications. In SSIs, a significant prevalence of biliary culture positive for E. coli, Klebsiella pneumoniæ and Enterococcus fæcalis (p < 0.001) was detected. Prevalences of polymicrobial biliary cultures with Escherichia coli, Klebsiella pneumoniæ, Enterococcus fæcalis and Enterococcus fæcium were significantly associated with POPF (p < 0.001). Biliary culture positive for Escherichia coli, Enterococcus fæcalis and Enterococcus fæcium showed a higher prevalence of intra-abdominal collection and DGE (p < 0.001). Notably, Escherichia coli was significantly associated with DGE as a unique complication (OR = 2.94 (1.30-6.70); p < 0.01). CONCLUSIONS Specific prevalences of polymicrobial bacterobilia are associated with major complications, while monomicrobial Escherichia coli bacterobilia is associated with DGE as a unique complication after PD.

Abstract
Aim In order to find the risk factors of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) according to the latest definition and grading system of International Study Group of Pancreatic Surgery (ISGPS) (version 2016) and propose a nomogram for predicting POPF. Methods We conducted a retrospective analysis of 232 successive cases of PD performed at our hospital by the same operator from August 2012 to June 2020. POPF was diagnosed in accordance with the latest definition of pancreatic fistula from the ISGPS. The risk factors of POPF were analyzed by univariate and multivariate logistic regression analysis. A nomogram model to predict the risk of POPF was constructed based on significant factors. Results There were 18 cases of POPF, accounting for 7.8% of the total. Among them, 17 cases were classified into ISGPF grade B and 1 case was classified into ISGPF grade C. In addition, 35 cases were classified into biochemical leak. Univariate and multivariate analysis showed that hypertension, non-diabetes, no history of abdominal surgery, antecolic gastrojejunostomy and soft pancreas were independent risk factors of POPF. Based on significant factors, a nomogram is plotted to predict the risk of POPF. The C-index of this nomogram to assess prediction accuracy was 0.916 (P < 0.001) indicating good prediction performance. Conclusion Hypertension, non-diabetes, no history of abdominal surgery, antecolic gastrojejunostomy and soft pancreas were independent risk factors of POPF. Meanwhile, a nomogram for predicting POPF with good test performance and discriminatory capacity was constituted.

Abstract
BACKGROUND Wrapping pancreatojejunal anastomosis with omentum to prevent postoperative pancreatic fistula (POPF) has only been reported in non-randomized, controlled trials. Therefore, this study aimed to conduct a randomized, controlled trial to compare outcomes between omental roll-up and non-omental roll-up in pancreatojejunal anastomosis. METHODS This single-center, randomized, two-arm trail (Clinical Trials Register: NCT03083938) was conducted between February 2017 and February 2019. We studied 34 patients in the omental roll-up group and 34 patients in the non-omental roll-up group. The primary endpoint was the incidence of clinically relevant POPF. Thirty-day mortality and morbidity were recorded. RESULTS Patients' demographic data were not significantly different between the two groups, except for histological diagnosis, with a significantly higher incidence of pancreatic cancer in the omental roll-up group (n = 15, 44.1%) than in the non-omental roll-up group (n = 9, 26.4%) (P = 0.042). There was one death in the non-omental roll-up group due to myocardial infarction. The incidence of POPF was not different between the omental roll-up group (n = 5, 14.7%) and non-omental roll-up group (n = 7, 20.6%) (P = 0.525). No differences were found in postoperative hemorrhage after pancreatectomy, delayed gastric emptying, and chyle leakage between the groups. CONCLUSION This study shows that omental roll-up does not decrease the incidence of POPF after pancreatoduodenectomy.

Abstract
Background Pancreatic cancer is one of the most aggressive and lethal tumours in Western society. Pancreatic surgery can be considered a challenge for open and laparoscopic surgeons, even if the accuracy of gland dissection, due to the close relationship between pancreas, the portal vein, and mesenteric vessels, besides the reconstructive phase (in pancreaticoduodenectomy), lead to significant difficulties for laparoscopic technique. Minimally invasive pancreatic surgery changed utterly with the development of robotic surgery. However, this review aims to make more clarity on the influence of robotic surgery on long-term morbidity. Methods A systematic literature search was performed in PubMed, Cochrane Library, and Scopus to identify and analyze studies published from November 2011 to September 2020 concerning robotic pancreatic surgery. The following terms were used to perform the search: "long term morbidity robotic pancreatic surgery". Results Eighteen articles included in the study were published between November 2011 and September 2020. The review included 2041 patients who underwent robotic pancreatic surgery, mainly for a malignant tumour. The two most common robotic surgical procedures adopted were the robotic distal pancreatectomy (RDP) and the robotic pancreaticoduodenectomy (RPD). In two studies, patients were divided into groups; on the one hand, those who underwent a robotic pancreaticoduodenectomy (RPD), on the other hand, those who underwent robotic distal pancreatectomy (RDP). The remaining items included surgical approach such as robotic middle pancreatectomy (RMP), robotic distal pancreatectomy and splenectomy, robotic-assisted laparoscopic pancreatic dissection (RALPD), robotic enucleation of pancreatic neuroendocrine tumours. Conclusions Comparison between robotic surgery and open surgery lead to evidence of different advantages of the robotic approach. A multidisciplinary team and a surgical centre at high volume are essential for better postoperative morbidity and mortality.

Abstract
Pancreatic fluid collections (PFC) are notorious for their extension beyond the normal confines of the pancreatic bed. This distribution is explained by dissection along the fascial planes in retroperitoneum due to the digestive enzymes within the PFC. In genitourinary track, PFCs have been described to involve the kidneys and the ureters. We report a case of severe acute necrotizing pancreatitis in a 28-year-old male, chronic alcoholic, who on readmission developed features of cystitis. The urine was turbid but did not show significant bacteriuria. Close location of the PFC near the urinary bladder (UB) prompted evaluation of urinary lipase and amylase. Elevated urinary enzyme levels suggested a Pancreatico-vesical fistula, conclusive demonstration of which was established by CT cystography. Percutaneous drainage of the necrosum and stenting of pancreatic duct led to spontaneous healing of the pancreatico-vesical fistula. Our case reiterates the remarkable property of pancreatic enzymes to dissect the fascial planes which is demonstrated by decompression of PFC via UB causing spontaneous Pancreatico-vesical fistula. Further, presence of main pancreatic duct fistulization should prompt endoscopic-guided stenting to obliterate the communication with the fistula and accelerate healing.

Increased postoperative pancreatic fistula rate after distal pancreatectomy compared with pancreatoduodenectomy is attributable to a difference in acinar scores. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2021; 28:533-541. [PMID: 33665934 DOI: 10.1002/jhbp.934] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/24/2020] [Revised: 11/15/2020] [Accepted: 11/20/2020] [Indexed: 12/30/2022]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is a potentially lethal complication of pancreatic surgery. POPF rate is consistently higher after distal pancreatectomy (DP) compared with pancreatoduodenectomy (PD). The acinar score of the remnant pancreas is associated with postoperative pancreatitis and POPF. This study aimed to: (i) confirm the difference in POPF rate after DP vs PD; (ii) confirm the association between acinar score and POPF; and (iii) evaluate the difference in acinar scores between DP and PD. METHODS Patients undergoing DP or PD at a single institution from 2011 to 2017 were included. Hematoxylin and eosin-stained slides of the pancreatic resection margin were evaluated for all patients and scored for acinar cell density. Clinicopathological data were retrieved from a prospectively maintained database. RESULTS Two hundred and ninety-four patients were included in the analysis (206 PD, 88 DP). The POPF rate was significantly higher after DP than PD (20.4% vs 11.2%, P = .043). Acinar score >50 was independently associated with the development of POPF (OR 6.457, P = .003). DP was associated with a higher median acinar score than PD (65 vs 50, P < .001). CONCLUSION The POPF rate is significantly higher after DP compared with PD and is attributable to a higher acinar score of the pancreatic resection margin.

Abstract
Background: Laparoscopic pancreaticoduodenectomy has developed rapidly in recent years. Postoperative pancreatic fistula is still the most dangerous complication of laparoscopic pancreaticoduodenectomy. Baumgart pancreaticojejunostomy is considered one of the safest anastomosis procedures, with low rates of pancreatic fistula. We modified Blumgart pancreaticojejunostomy and applied the modified procedure during laparoscopic pancreaticoduodenectomy. The modified procedure entailed a longitudinal U-shaped suture through the pancreas for anastomosis of the pancreatic duct and the jejunal mucosa. Methods: We prospectively collected and retrospectively analyzed the data of 120 patients who underwent laparoscopic pancreaticoduodenectomy from January 2016. The total operative time, time for complete pancreaticojejunostomy, postoperative pancreatic fistula rate, postoperative delayed gastric emptying, postoperative bleeding, postoperative length of hospital stays, and mortality within 90 days after surgery were analyzed. An analysis of laparoscopic pancreaticojejunostomy compared with open pancreaticojejunostomy is also reported. Results: In the laparoscopic pancreaticojejunostomy group, the average total operative time, the average time for complete pancreaticojejunostomy, and the average intraoperative blood loss were 271 min, 35.3 min, and 184 ml, respectively. The total postoperative clinically relevant pancreatic fistula rate was 9.2% (Grade B and C fistulas). The incidence rates of postoperative delayed gastric emptying and postoperative biliary fistula were ~2.5 and 1.7%, respectively. The postoperative bleeding rate was 0.83%, and the average postoperative indwelling time of the abdominal drainage tube was 7.3 days. The postoperative length of hospital stay was 10.8 days, and the mortality rate within 90 days after surgery was 0.83%. The rates of clinically relevant postoperative clinically relevant pancreatic fistula are comparable between laparoscopic and open surgery, there were no other severe postoperative complications in either group. The mean postoperative length of hospital stay was significantly shorter in the laparoscopic pancreaticojejunostomy group. Conclusion: The modified laparoscopic-adapted Blumgart anastomosis simplifies and facilitates the creation of the pancreaticojejunostomy in laparoscopic pancreaticoduodenectomy. The rates of clinically relevant postoperative pancreatic fistula are comparable with those obtained by open surgery, and length of stay are shoter.

Lack of Association between Postoperative Pancreatitis and Other Postoperative Complications Following Pancreaticoduodenectomy. J Clin Med 2021; 10:jcm10061179. [PMID: 33799863 PMCID: PMC8001526 DOI: 10.3390/jcm10061179] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Revised: 03/02/2021] [Accepted: 03/09/2021] [Indexed: 12/15/2022] Open
Abstract
Background: Prediction of post-pancreaticoduodenectomy (PD) morbidity is difficult, especially in the early postoperative period when CT (Computed Tomography) scans are not available. Elevated serum amylase and lipase in postoperative day 0 or 1 may be used to define postoperative acute pancreatitis (POAP), but the existing literature does not agree on whether POAP is significantly associated with postoperative pancreatic fistula (POPF). Methods: We analyzed the data obtained from a previously published randomized controlled trial. POAP was defined as elevations in serum amylase above 110 U/L on postoperative day 0 or 1. Clinically relevant POAP (CR-POAP) was defined as elevations in C-reactive protein level (CRP) on postoperative day 2 in those with POAP. Postoperative complications including severe complications (Clavien–Dindo ≥ IIIa), POPF, and clinically relevant POPF (CR-POPF) were analyzed. Results: In 246 patients, POAP did not show significant associations with total postoperative complications (odds ratio (OR) 0.697; 95% CI, 0.360–1.313; p = 0.271), severe complications (OR 0.647; 95% CI, 0.258–1.747; p = 0.367), and CR-POPF (OR 0.998; 95% CI, 0.310–3.886; p = 0.998) in multivariable analysis. Conclusions: In patients undergoing PD, POAP was not significantly associated with postoperative complications including POPF. Caution should be taken when using POAP as a predictor of POPF.

Abstract
OBJECTIVES In patients with surgically altered anatomy, endoscopic treatment of pancreatic diseases is technically challenging. We aimed to evaluate the feasibility, effectiveness, and safety of an interchangeable combination of double-balloon endoscope-assisted ERP (DB-ERP) and endoscopic ultrasonography-guided pancreatic duct drainage (EUS-PD) in this clinical setting. METHODS Consecutive patients with surgically altered anatomy undergoing endoscopic treatment (DB-ERP, EUS-PD, or both) for pancreatic diseases were studied. The primary outcome was technical success; secondary outcomes were clinical success and adverse events. RESULTS Forty patients who underwent DB-ERP (38) and EUS-PD (2) as an initial intervention were retrospectively studied. Indications for intervention included 18 pancreaticojejunostomy anastomotic stricture (PJAS), four pancreatic duct stone (PDS), four pancreatic fistula (PF), 11 PJAS with PDS, and three PJAS with PF. Prior surgical reconstruction was 26 Billroth-II, 13 Roux-en-Y, and one Imanaga reconstruction. Along with salvage procedures including three DB-ERP and seven EUS-PD, the overall technical success rates of DB-ERP and EUS-PD were 70.7% (29/41) and 100% (9/9), respectively. Clinical success was achieved in 85.0% (34/40) by combination of DB-ERP and EUS-PD; successful drainage for PJAS, complete removal of PDS, and resolution of PF were achieved in 90.6%, 80.0%, and 71.4%, respectively. Adverse event rates were 12.2% (5/41; one perforation, and four pancreatitis) in DB-ERP and 55.6% (5/9; three pancreatic leakage, and two abdominal pain) in EUS-PD. CONCLUSIONS A combination of DB-ERP and EUS-PD can achieve high technical and clinical success for pancreatic diseases in surgically altered anatomy patients. A prospective multicenter study to investigate an appropriate treatment algorithm is warranted.

Abstract
INTRODUCTION Pancreaticoduodenectomy is the preferred treatment of neoplasms in the pancreas and duodenum. Postoperative pancreatic fistula is a critical complication. A potential predictive marker is C-reactive protein. This retrospective study examined the predictive value of C-reactive protein as a marker for development of postoperative pancreatic fistulas. METHODS All patients who had a pancreaticoduodenectomy from 1 January 2015 to 31 December 2019, were included. Levels of the biomarker and linear trajectory were determined for postoperative days one to four. Univariate analysis was used to identify predictive variables for a postoperative pancreatic fistula. Receiver operating characteristics curves, specificity, and sensitivity were calculated. RESULTS Five hundred and fifty-two patients underwent pancreaticoduodenectomy. C-reactive protein level greater than 121.5mg/L on the third postoperative day and an increase in C-reactive protein level between the first and fourth postoperative days, greater than 21.7mg/L, seemed to be reliable predictors. For Grade C postoperative pancreatic fistulas, increases in C-reactive protein, greater than 40.6ml/L the first four postoperative days, had a sensitivity of 100%. White blood cell count did not have similar reliability in predicting postoperative pancreatic fistulas. CONCLUSION Our findings indicate that small rises in C-reactive protein during the first postoperative days after pancreaticoduodenectomy are associated with an increased risk of developing postoperative pancreatic fistula.

Abstract
OBJECTIVE To study the immediate results of pancreatoduodenectomy depending on digestive reconstruction procedure. MATERIAL AND METHODS We analyzed 242 patients who underwent pancreatoduodenectomy for the period from January 2013 to December 2019. There were 32 combined procedures: 28 (11.6%) with portal vein resection and 8 (3.3%) simultaneous operations (right-sided hemicolectomy - 4, right-sided adrenalectomy - 2, gastrectomy with splenectomy - 2). Pancreatic stump was inserted into the jejunum in 156 (64.5%) patients, into the stomach - in 86 (35.5%) cases. RESULTS Postoperative period was uneventful in 180 (74.4%) patients. Eighty postoperative complications were observed in 62 (25.6%) patients; 221 (91.3%) patients were discharged, 21 (8.7%) patients died. Pancreatic necrosis was the most common postoperative event and provoked 65 (82.5%) various complications (38 (72.1%) in patients with pancreaticojejunostomy and 20 (71.5%) in those with pancreaticogastrostomy). Incidence of complications was similar in both groups. However, pancreaticojejunostomy was followed by severe pancreatic fistula type C in 12 (23.1%) patients, type B in 24 (46.1%) cases. In case of pancreaticogastrostomy, pancreatic fistula type C occurred in 4 (14.3%) cases, type B - in 8 (28.6%) patients. CONCLUSION Pancreatic necrosis was the most common postoperative event after pancreatoduodenectomy. Fewer severe pancreatic fistulae (type C) were recorded after pancreaticogastrostomy although these patients had lower density of the pancreas and unclear pancreatic duct. Choice of pancreatic-digestive anastomosis should be determined by features of pancreatic parenchyma, pancreatic duct diameter. Nevertheless, final decision is a prerogative of surgeon. Pancreaticogastrostomy is especially advisable in minimally invasive PDEs that will simplify inclusion of the pancreas into digestive system and reduce the incidence of complications and mortality.

Abstract
BACKGROUND Pancreas transplantation (PT) is a radical treatment for diabetes mellitus (DM). Although the results of PT have been improving, surgical complications remain. Few reports have focused on complications associated with pancreatic fluid (CAPF) after PT. We aimed to investigate the risk factors and predictors for CAPF after PT. METHODS Sixty-nine patients, who underwent deceased-donor PT for type 1 DM at our institution from August 2001 to May 2020, were retrospectively studied. We identified CAPF from those with Clavien-Dindo Classification ≥grade III and assessed risk factors by univariate and multivariate analyses using logistic regression. RESULTS Twenty-one (30.4%) patients had complications with Clavien-Dindo Classification ≥grade III. Eleven (16.0%) patients were diagnosed with CAPF. Median serum pancreatic amylase (P-AMY) levels with CAPF on postoperative day (POD)1 and POD2 were significantly higher than those without CAPF (P = .019 and P = .027, respectively). In multivariable analysis, serum P-AMY levels on POD1 were an independent predictive factor for CAPF (odds ratio 1.83, 95% confidence interval 1.07-3.14, P = .008). CONCLUSIONS Complications associated with pancreatic fluid after PT is associated with high serum P-AMY in the early postoperative period. Serum pancreatic enzymes in the first few postoperative days after PT may be a significant predictive factor for CAPF.

Abstract
BACKGROUND The incidence of postoperative pancreatic fistula (POPF) after distal pancreatectomy (DP) remains high. The present study aimed to clarify the efficacy of our modified DuVal (mDuVal) pancreatojejunostomy following DP in patients with a high risk of POPF. METHODS The medical records of 346 consecutive patients who underwent DP between 2006 and 2016 were retrospectively reviewed. Perioperative features were compared between 24 patients undergoing mDuVal (mDuVal group) and 322 patients undergoing standard DP (standard DP group). RESULTS Preoperative American Society of Anesthesiologists physical status 1 was more frequent in the standard group than in the mDuVal group (P = .02). The start of a solid diet after operation was significantly earlier in the mDuVal group than in the standard DP group (P = .01), while there were no significant differences between the groups for clinically relevant POPF, amylase concentration in the drainage fluid on postoperative day 1 and days 3-5, time to drain removal, additional intervention for POPF, overall complications, or postoperative hospital stay. DISCUSSION The mDuVal procedure could be an option for patients with a high risk of POPF to improve the outcomes after DP. Further investigation involving large study populations is necessary to clarify the efficacy of this procedure.
