ABSTRACT
Postoperative pancreatic fistula (POPF) is the most feared complication following pancreatic resection. Octreotide, a synthetic somatostatin analog, has been widely used by pancreatic surgeons worldwide after pancreatic resections, often as per surgeon抯 discretion, to prevent POPF especially in cases at high risk of developing POPF. We herein analyze the data available till date of the subject. A PubMed search with keywords 搒omatostatin OR octreotide OR somatostatin analogues AND postoperative pancreatic fistula� was made. Further filters were applied in the search 揅linical Trial, Meta?Analysis, Randomized Controlled Trial, Systematic Review, from 1990 � 2021,� and the 68 results thus obtained were analyzed and included in this narrative review. There is considerable heterogeneity among the studies assessing the role of octreotide in the prevention of POPF making data comparison difficult, and hence results remain inconclusive. Most of the earlier studies used different definitions of POPF and other complications; included patients with varied pancreatic pathologies such as cancer, chronic pancreatitis, and benign lesions; surgical techniques such as pancreaticoduodenectomy, distal pancreatectomy, and other procedures; use of somatostatin and its analogs such as octreotide, lanreotide, pasireotide, and vapreotide; varied surgeon and institutional volume; and so on. Besides, pancreatic surgery is per se a complex surgical procedure and has its own inherent biases related to patient and the pancreas itself affecting the overall outcome. Data indicate favorable role of newer somatostatin analogs, and further studies are urgently needed. The question about the efficacy of prophylactic octreotide to reduce POPF after pancreaticoduodenectomy remains open to debate
ABSTRACT
Objective:To analyze the risk factors of clinically-relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD) and penetrating pancreaticojejunostomy (PPJ).Methods:The clinical data of 108 patients who underwent PD and PPJ in the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Wannan Medical College from January 2017 to October 2022 were analyzed retrospectively, including 65 males and 43 females, aged 65.5 (54.2, 72.0) years. The incidences of POPF, biliary fistula, abdominal bleeding and other related complications were reviewed. The related factors of CR-POPF were analyzed by univariate analysis, and the statistically significant factors were included in multivariate logistic regression analysis.Results:A total of 108 patients were successfully treated with PD, including laparoscopic PD in 76 cases (70.4%) and open PD in 32 cases (29.6%). PPJ was performed in PD, including the continuous fashion in 39 cases (36.1%), intermittent fashion in 49 cases (45.4%) and modified continuous fashion in 20 cases (18.5%). The operation time was 390.0 (314.0, 480.0) min, the intraoperative blood loss was 200.0 (100.0, 384.0) ml, the postoperative hospital stay was 12.0 (10.0, 15.0) d, and the incidence of POPF (grade B + C) was 11.1% (12/108). Body mass index, pancreatic CT value and pancreatic duct size were the significant factors of CR-POPF (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=0.895, 95% CI: 0.822-0.975), pancreatic CT value ( OR=0.812, 95% CI: 0.698-0.946) and pancreatic duct size ( OR=0.457, 95% CI: 0.220-0.952) were risk factors of CR-POPF after PPJ (all P<0.05). Conclusion:PPJ is a safe method of pancreaticoenterostomy, and CR-POPF may be related to younger patients, lower pancreatic CT value and the smaller pancreatic duct size.
ABSTRACT
Objective:To investigate feasibility, efficiency and safety of kissing pancreatojejunostomy after pancreatoduodenectomy.Methods:From Jan 2006 to Sep 2020, the clinical data of 267 patients undergoing pancreatoduodenectomy and kissing pancreatojejunostomy were retrospectively analyzed.Results:Grade B postoperative pancreatic fistula (POPF) occurred in 6.37%, Grade C POPF in 2.25% of patients. There was no mortality within 30 days postoperatively as to pancreatic fistula, by cut-off of pancreatic duct diameter at 3mm, there was no significant difference between two subgroups (15/140 vs. 8/127, P=0.20). also, when grouped by texture of the pancreas, no there was significant difference (20/194 vs. 3/73, P=0.11). Conclusions:Kissing pancreatojejunostomy is feasible and easy to perform. It also does not increase the POPF rate when applied to the pancreatojejunostomy with thin pancreatic duct and soft texture.

ABSTRACT
Objective@#To investigate the prognostic factors of hyperamylasemia following pancreaticoduodenectomy (PD) .@*Methods@#Clinical data of 359 patients were collected prospectively who underwent PD by the same group at Changhai Hospital of Navy Medical University from January 2017 to June 2018.There were 212 males and 147 females.The median age was 63 years old (range: 23 to 82 years old) .According to whether the patient′s serum amylase was greater than 120 U/L at 0 or 1 day after surgery,the patients were divided into hyperamylasemia group and non-hyperamylasemia group. Univariate analysis and multivariate analysis were used to find out the prognostic factors of hyperamylasemia after PD.@*Results@#Of the 359 patients, 238 cases (66.3%) developed hyperamylasemia.The incidence rate of clinically related pancreatic fistula (15.1% vs.2.5%, P<0.01) , grade B/C post pancreatectomy hemorrhage (8.8% vs. 2.5%, P<0.01) , and surgical site infection (9.2% vs. 3.3%, P=0.04) was significantly higher in the hyperamylasemia group.The severity of complications (CD grade≥Ⅲ: 11.3% vs.4.1%, P=0.023) and postoperative hospital stay (11 days vs. 9 days, P=0.001) were higher in the hyperamylasemia group.In the multivariate analysis, the main pancreatic duct diameter (MPD) ≤3 mm (OR=4.469, 95% CI: 2.563-7.793, P<0.01) , pathological type of disease (pancreatic cancer or pancreatitis) (OR=0.230, 95% CI: 0.122-0.436, P<0.01) and soft texture of pancreas (OR=3.297, 95%CI: 1.930-5.635, P<0.01) were independent prognostic factors for hyperamylasemia.@*Conclusions@#Post-PD hyperamylasemia increased the incidence and severity of postoperative complications after PD.MPD≤3 mm, soft texture of pancreas and pathological type of disease were independent prognostic factors of hyperamylasemia.
ABSTRACT
Objective To study the relationship of early postoperative CRP and PCT with pancreatic fistula after pancreaticoduodenectomy (PD);to study whether the combination of CRP and PCT can be used as an early predictor of pancreatic fistula;and to determine the optimal cut-off values of CRP and PCT for early diagnosis of pancreatic fistula after PD.Methods Postoperative pancreatic fistula and other complications were recorded in 82 patients after PD carried out at the Anshan Iron and Steel Group General Hospital from January 2013 to May 2017.PCT and CRP were measured on the 1st to the 5th postoperative day (POD).CRP and PCT were compared between the pancreatic fistula group and the non-complication group on pancreatic fistula prediction.The sensitivity,specificity,and combined sensitivity,combined specificity,negative predictive value,positive predictive value and optimal cut-off value were calculated.Results 56 patients developed postoperative complications,including 17 patients with pancreatic fistula,and 39 patients with non-pancreatic fistula.The postoperative CRP and PCT were correlated with postoperative pancreatic fistula and with other complications.The higher the CRP and PCT,the higher the risk of postoperative pancreatic fistula.The ROC curves suggested that CRP and PCT had a high predictive value for pancreatic fistula,especially on POD 2.The optimal cut-off value of CRP was 189.05 mg/L,the sensitivity was 94.1％,the specificity was 81.5％,the positive predictive value was 94.7％,and the negative predictive value was 24.4％.The optimal cut-off value of PCT was 0.89 mg/dl,the sensitivity was 88.2％,the specificity was 84.6％,the positive predictive value was 91.3％,and the negative predictive value was 20.5％.The sensitivity and specificity of combined CRP with PCT on POD 2 in predicting pancreatic fistula after operations were 100％ and 69.1％,respectively.Conclusion Combined CRP and PCT had a high early predictive rate in the identification of pancreatic fistula after PD.
ABSTRACT
Objective To explore perioperative risk factors for postoperative pancreatic fistu?la. Methods Six hundred and forty?three cases patients who underwent radical gastrectomy for gastric cancer from January 2010 to June 2015 in the NO. 309 Hospital of Chinese People’ s Liberation Army were selected and divided into Postoperative Pancreatic Fistula( POPF) group with 53 cases and Non?Postoperative Pancreatic Fis?tula( NPOPF) group with 590 cases. Preoperative,intraoperative and postoperative data were analyzed by statisti?cal analysis of two groups. Results POPF rate was 8. 24%(53/643). There were no significanct differences in terms of gender,age,preoperation with disease,preoperative serum albumin,TNM stage,abdominal surgery,sur?gical procedure,lymph node dissection,digestive tract reconstruction,surgical approach,blood loss and length of time between the POPF group and NPOP group(P>0. 05). The level of BMI of POPF group was higher than that of NPOPF group,the difference was statistically significant((25. 63±2. 54) kg/m2 vs. (21. 11±2. 44) kg/m2,t=2. 245,P=0. 025). The number of lymph node dissection in POPF group was (32. 25±5. 82),in NPOPF group was (27. 06±6. 79),there was significant difference between the two groups(t=2. 093,P=0. 037). The operation time in POPF group was (242. 50±52. 30) min,in NPOPF group was (229. 51±59. 21) min,the difference was statistically significant between the two groups( t=2. 398,P=0. 017) . The serum CRP of 1 d in POPF group was (85. 72±12. 05) mg/L,in NPOPF group was (76. 41±12. 52) mg/L,and there was significant difference between the two groups( t=1. 979,P=0. 048) . The serum albumin of 2?4 d after operation in POPF group was (26. 0±5. 9) g/L,in NPOPF group was (32. 6±6. 8) g/L,the difference between the two groups was statistically significant(t=-10. 185,P=0. 000). The drainage fluid amylase of 1 and 2 d after operation in POPF group was (2094+1444) U/L,in NPOPF group was (746+486) U/L,and there was significant difference be?tween the two groups( t=10. 400,P=0. 000) . Logistic regression analysis results showed that body mass index ( BMI) ,lymph node dissection number,time of operation,postoperative 1,2 d drainage fluid amylase and serum albumin of 2?4 d after operation were postoperative occurred pancreatic fistula risk factors( OR=1. 972,183. 6, 2. 004,0. 150,9. 809,P>0. 05). Conclusion BMI,number of dissected lymph node,duration of surgery,serum albumin of 2?4 d after operation and postoperative 1,2 d drainage fluid amylase have important clinical values for predicted POPF.
ABSTRACT
Portal vein thrombosis (PVT) is a rare but serious postoperative complication of pancreaticoduodenectomy (PD). We reported a case of late-onset postoperative PVT with hemorrhage from the common hepatic artery (CHA) in a 73-year-old man who underwent pylorus-preserving pancreaticoduodenectomy (PPPD) for duodenum papilla cancer, followed by reconstruction using the modified Child's technique. The pancreaticojejunostomy was achieved by end-to-side, 2-layer invagination anastomosis without pancreatic duct stenting. Drain removal and hospital discharge were scheduled on postoperative day (POD) 18, but blood-stained fluid in the drain and sudden hematemesis were noted. Emergency surgery was performed because PVT and imaging findings were suggestive of necrosis of the lifted jejunum. Although no jejunal necrosis was identified during surgery, bleeding from the side of the CHA was detected and the bleeding point was suture-closed to achieve hemostasis. We suspected late-onset postoperative arterial hemorrhage and subsequent hematoma formation, which caused portal vein compression and PVT formation. We chose a conservative treatment strategy for PVT, taking into account the operation time, intraoperative vital signs and blood flow in the portal vein. Despite the complicated postoperative course, he was discharged home in a fully ambulatory state on POD 167.

In recent years,postoperative mortality rate of pancreatic resection has dropped below 5％,while the complication rate still remains as high as 30％ ～ 50％.Postoperative pancreatic fistula and abdominal abscess are two serious complications after pancreatic resection,with the incidence of 10％ ～28％.Deep understanding of the physiological functions of the pancreas together with the research and development of new medications has improved the prognosis of patients with pancreatic fistula.This article gave a brief overview on the progress in this regard.
