Revealing the role of early peripancreatic bacterial contamination and Enterococcus faecalis in pancreatic fistula development after pancreaticoduodenectomy: Implications for useful antibiotic prophylaxis-An observational cohort study. Pancreatology 2024; 24:630-642. [PMID: 38508910 DOI: 10.1016/j.pan.2024.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 02/26/2024] [Accepted: 03/13/2024] [Indexed: 03/22/2024]
Abstract
BACKGROUND Peripancreatic bacterial contamination (PBC) is a critical factor contributing to the development of clinically relevant postoperative pancreatic fistula (CR-POPF) following pancreaticoduodenectomy (PD). Controlling pathogenic bacteria is essential in preventing CR-POPF; however, the precise relationship between specific bacteria and CR-POPF remains unclear. This study aimed to investigate the relationship between PBC and CR-POPF after PD, with a focus on identifying potentially causative bacteria. METHODS This prospective observational study enrolled 370 patients who underwent PD. Microbial cultures were routinely collected from peripancreatic drain fluid on postoperative days (PODs) 1, 3, and 6. Predictive factors for CR-POPF and the bacteria involved in PBC were investigated. RESULTS CR-POPF occurred in 86 (23.2%) patients. In multivariate analysis, PBC on POD1 (Odds ratio [OR] = 3.59; P = 0.005) was one of the main independent predictive factors for CR-POPF, while prophylactic use of antibiotics other than piperacillin/tazobactam independently influenced PBC on POD1 (OR = 2.95; P = 0.010). Notably, Enterococcus spp., particularly Enterococcus faecalis, were significantly isolated from PBC in patients with CR-POPF compared to those without CR-POPF on PODs 1 and 3 (P < 0.001), and they displayed high resistance to all cephalosporins. CONCLUSIONS Early PBC plays a pivotal role in the development of CR-POPF following PD. Prophylactic antibiotic administration, specifically targeting Enterococcus faecalis, may effectively mitigate early PBC and subsequently reduce the risk of CR-POPF. This research sheds light on the importance of bacterial control strategies in preventing CR-POPF after PD.

Perioperative pancreaticoduodenectomy management strategy focusing on postoperative early drain colonization. Surg Today 2024:10.1007/s00595-024-02810-4. [PMID: 38502211 DOI: 10.1007/s00595-024-02810-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2023] [Accepted: 01/21/2024] [Indexed: 03/21/2024]
Abstract
PURPOSE Pancreatoduodenectomy (PD) is a highly invasive procedure. Intra-abdominal infections and pancreatic fistulas are strongly correlated complications. In the present study, we identified the risk factors for postoperative early drain colonization (POEDC) and established a perioperative management strategy. METHODS A total of 205 patients who underwent pancreatoduodenectomy were included in the study. POEDC was defined as a positive drain fluid culture before postoperative day (POD) 4. We retrospectively investigated the correlation between POEDC, postoperative outcomes, and clinical factors. RESULTS POEDC was observed in 26 patients (12.6%) with poor postoperative outcomes, including pancreatic fistulas (P < 0.001). A multivariate analysis demonstrated a correlation between these postoperative outcomes and the age (P = 0.002), body mass index (BMI) (P = 0.002), procalcitonin (PCT) level (P < 0.001), and drain amylase level on POD 1 (P = 0.032). Enterococcus was detected most frequently, being found in 15 patients. CONCLUSION We observed a strong correlation between POEDC and poor postoperative outcomes. The BMI, age, and PCT and drain amylase level on POD 1 should be considered POEDC risk factors, with the need to propose an antibiotic perioperative strategy. POEDC control may represent the key to improving postoperative outcomes after PD.

Ann Gastroenterol Surg 2024; 8:301-311.

Abstract
Background There have been few studies of countermeasures against postoperative cholangitis, a serious complication after pancreaticoduodenectomy (PD) that impairs quality of life. Objective To evaluate our recently developed, novel method of choledochojejunostomy with a larger anastomotic diameter, the "T-shaped anastomosis." Methods The study included 261 cases of PD. The T-shaped choledochojejunostomy technique was performed with an additional incision for a distance greater than half the diameter of the bile duct at the anterior wall of the bile duct and the anterior wall of the elevated jejunum. To compensate for potential confounding biases between the standard anastomosis group (n = 206) and the T-shaped anastomosis group (n = 55), we performed propensity score matching (PSM). The primary endpoint was the incidence of medium-term postoperative cholangitis adjusted for PSM. Results In the PSM analysis, 54 patients in each group were matched, and the median bile duct diameter measured by preoperative CT was 8.8 mm versus 9.3 mm, the rate of preoperative biliary drainage was 31% versus 37%, the incidence of cholangitis within 1 month before surgery was 9% versus 13%, and the incidence of postoperative bile leakage was 2% versus 2%, with no significant differences. The incidence of medium-term postoperative cholangitis was 15% versus 4%, and multivariate logistic regression revealed that T-shaped choledochojejunostomy was an independent predictor of a reduced incidence of cholangitis (odds ratio, 0.17, 95% CI 0.02-0.81; p = 0.024). Conclusions The T-shaped choledochojejunostomy technique was shown to be effective with a significant reduction in the incidence of medium-term postoperative cholangitis. Clinical trial identification: UMIN000050990.

Abstract
PURPOSE The preoperative platelet-to-lymphocyte ratio (PLR) has been reported as an important prognostic index for pancreatic ductal adenocarcinoma (PDAC); however, the significance of the postoperative (post-op) PLR for this disease has not been elucidated. METHODS We analyzed data on 118 patients who underwent pancreaticoduodenectomy for pancreatic head PDAC, collected from a prospectively maintained database. The post-op PLR was obtained by dividing the platelet count after surgery by the lymphocyte count on post-op day (POD) 14. The patients were divided into two groups according to a post-op PLR of < 310 or ≥ 310. Survival data were analyzed. RESULTS A high post-op PLR was identified as a significant prognostic index on univariate analysis for disease-free survival (DFS) and overall survival (OS). The post-op PLR remained significant, along with tumor differentiation and adjuvant chemotherapy, on multivariate analysis for OS (hazard ratio = 2.077, 95% confidence interval: 1.220-3.537; p = 0.007). The post-op PLR was a significant independent prognostic index for poor DFS, along with tumor differentiation and lymphatic invasion, on multivariate analysis (hazard ratio = 1.678, 95% confidence interval: 1.056-2.667; p = 0.028). CONCLUSIONS The post-op PLR in patients with pancreatic head PDAC was an independent predictor of DFS and OS after elective resection.

Abstract
BACKGROUND Cancer-free resection (R0) is one of the most important factors for the long-term survival of biliary carcinoma. For some patients with widespread invasive cancer located between the hilar and intrapancreatic bile duct, hepatopancreaticoduodenectomy (HPD) is considered a radical surgery for R0 resection. However, HPD is associated with high morbidity and mortality rates. Furthermore, previous reports have not shown lymph node metastasis (LNM) status, such as the location or number, which could influence the prognosis after HPD. In this study, first, we explored the prognostic factors for survival, and second, we evaluated whether the LNM status (number and location of LNM) would influence the decision on surgical indications in patients with widely spread biliary malignancy. METHODS We retrospectively reviewed the medical records of 54 patients who underwent HPD with hepatectomy in ≥2 liver sectors from January 2003 to December 2021 (HPD-G). We also evaluated 54 unresectable perihilar cholangiocarcinoma patients who underwent chemotherapy from January 2010 to December 2021 (CTx-G). RESULTS R0 resection was performed in 48 patients (89%). The median survival time (MST) and 5-year overall survival rate of the HPD-G and CTx-G groups were 36.9 months and 31.1%, and 19.6 months and 0%, respectively. Univariate and multivariate analyses showed that pathological portal vein involvement was an independent prognostic factor for survival (MST: 18.9 months). Additionally, patients with peripancreatic LNM had worse prognoses (MST: 13.3 months) than CTx-G. CONCLUSIONS Patients with peripancreatic LNM or PV invasion might be advised to be excluded from surgery-first indications for HPD.

Abstract
Background A potential downside of robotic pancreatoduodenectomy (RPD) is the lack of tactile feedback when tying sutures, which could be especially perilous during pancreatic anastomosis. Near-infrared fluorescence imaging with indocyanine green (NIRF-ICG) could detect transpancreatic-suture-induced hypoperfusion of the pancreatic stump during RPD, which may be related to postoperative pancreatic fistula (POPF) grade B/C, but studies are lacking. Methods This prospective study included 37 patients undergoing RPD to assess the relation between pancreatic stump hypoperfusion as objectified with NIRF-ICG using Firefly and the rate of POPF grade B/C. In 27 patients, NIRF-ICG was performed after tying down the transpancreatic U-sutures. In 10 'negative control' patients, NIRF-ICG was performed before tying these sutures. Results Pancreatic stump hypoperfusion was detected using NIRF-ICG in 9/27 patients (33%) during RPD. Hypoperfusion was associated with POPF grade B/C (67% [6/9 patients] versus 17% [3/18 patients], P = 0.026). No hypoperfusion was objectified in 10 'negative controls'. Conclusions Transpancreatic-suture-induced pancreatic stump hypoperfusion can be detected using NIRF-ICG during RPD and was associated with POPF grade B/C. Surgeons could use NIRF-ICG to adapt their suturing approach during robotic pancreatico-jejunostomy. Further larger prospective studies are needed to validate the association between transpancreatic-suture-induced hypoperfusion and POPF.

Abstract
INTRODUCTION To investigate the application potential of single-layer continuous duct-to-mucosa pancreaticojejunostomy with two figure-of-eight sutures ("1 + 2" PJ) in total laparoscopic pancreaticoduodenectomy (TLPD). Explore the advantages of "1 + 2" PJ over the traditional double-layer interrupted duct-to-mucosa pancreaticojejunostomy (traditional PJ). METHODS We retrospectively collected the clinical data of 184 patients who were admitted in our department from Oct 2019 to Oct 2022, including 95 cases who underwent TLPD with "1 + 2" PJ and 89 cases who underwent TLPD with traditional PJ. The pre/intra/postoperation data were analyzed and compared. RESULTS The "1 + 2" PJ procedures were successfully performed in all the 95 cases. When compared with the traditional PJ group, there were no statistically significant variations between the pre-operative and pathological data. However, the "1 + 2" PJ group had a shorter operation time (235 (210, 300) minutes vs. 310 (270, 360) minutes in the traditional PJ group, P < 0.001), shorter pancreaticojejunostomy time (15 (10, 20) minutes vs. 50 (45, 55) minutes in the traditional PJ group, P < 0.001), lower pancreatic fistula (both grade B/C) rate (4.21% vs. 12.34% in the traditional group, P = 0.044), and abdominal infection rate (2.11% vs. 8.99% in the traditional group, P = 0.044), as well as reduced hospital stay (11 (9, 15) days vs. 13 (11, 15) days in the traditional PJ group, P = 0.013). In the "1 + 2" PJ group, the median diameter of the pancreatic duct was 3 (3, 4) mm; 82 cases (86.31%) had a normal pancreatic texture, while nine (9.47%) cases had a hard texture, and seven (7.37%) cases had a soft texture; the median intraoperative blood loss was 200 (100, 400) mL and 19 cases (20.00%) needed intraoperative transfusion; eight cases (8.4%) developed postoperative complications, including four cases (4.2%) of pancreatic fistula (including both grade B/C), one case (1.1%) of bile leakage, three cases (3.2%) of delayed gastric emptying, three cases (3.2%) of postoperative hemorrhage, two cases (2.1%) of abdominal infection, and one case (1.1%) of reoperation; the median hospital stay was 13 (8, 17) days; 25 cases were pathologically classified as pancreatic cancer, 35 cases as bile duct cancer, 23 cases as duodenal cancer, and 12 cases as ampullary cancer. CONCLUSION Single-layer continuous duct-to-mucosa pancreaticojejunostomy with two figure-of-eight sutures is a feasible and safe procedure that can be applied in TLPD.

[PMID: 37901736 PMCID: PMC10600778 DOI: 10.4240/wjgs.v15.i9.1901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 07/20/2023] [Accepted: 08/04/2023] [Indexed: 09/21/2023] Open
Abstract
BACKGROUND Pancreatoduodenectomy (PD) is the most effective surgical procedure to remove a pancreatic tumor, but the prevalent postoperative complications, including postoperative pancreatic fistula (POPF), can be life-threatening. Thus far, there is no consensus about the prevention of POPF. AIM To determine possible prognostic factors and investigate the clinical effects of modified duct-to-mucosa pancreaticojejunostomy (PJ) on POPF development. METHODS We retrospectively collected and analyzed the data of 215 patients who underwent PD between January 2017 and February 2022 in our surgery center. The risk factors for POPF were analyzed by univariate analysis and multivariate logistic regression analysis. Then, we stratified patients by anastomotic technique (end-to-side invagination PJ vs modified duct-to-mucosa PJ) to conduct a comparative study. RESULTS A total of 108 patients received traditional end-to-side invagination PJ, and 107 received modified duct-to-mucosa PJ. Overall, 58.6% of patients had various complications, and 0.9% of patients died after PD. Univariate and multivariate logistic regression analyses showed that anastomotic approaches, main pancreatic duct (MPD) diameter and pancreatic texture were significantly associated with the incidence of POPF. Additionally, the POPF incidence and operation time in patients receiving modified duct-to-mucosa PJ were 11.2% and 283.4 min, respectively, which were significantly lower than those in patients receiving traditional end-to-side invagination PJ (27.8% and 333.2 minutes). CONCLUSION Anastomotic approach, MPD diameter and pancreatic texture are major risk factors for POPF development. Compared with traditional end-to-side invagination PJ, modified duct-to-mucosa PJ is a simpler and more efficient technique that results in a lower incidence of POPF. Further studies are needed to validate our findings and explore the clinical applicability of our technique for laparoscopic and robotic PD.

Abstract
The established anastomotic techniques conventionally used in open surgery are increasingly being implemented in a minimally invasive approach and further developed. The aim of all innovations is to carry out a safe anastomosis with a feasible minimally invasive technique; however, there is currently no broad consensus about the role of laparoscopic and robotic surgery in performing pancreatic anastomotic techniques. Pancreatic fistulas determine the morbidity following a minimally invasive resection. The simultaneous minimally invasive resection and reconstruction of pancreatic processes and vascular structures is currently exclusively performed in specialized centers.

Abstract
BACKGROUND Postoperative pancreatic fistulas (POPFs) are considered inevitable in some patients after pancreaticoduodenectomy (PD), and measures to minimize their clinical impact are needed. Postpancreatectomy hemorrhage (PPH) and intra-abdominal abscess (IAA) are the most severe POPF-related complications, and concomitant leakage of contaminated intestinal content is considered the main cause. An innovative method, modified non-duct-to-mucosa pancreaticojejunostomy (TPJ), was created to prevent concomitant leakage of intestinal content, and its effectiveness was compared between two periods. METHODS All PD patients undergoing pancreaticojejunostomy from 2012 to 2021 were included. The TPJ group consisted of 529 patients recruited from January 2018 to December 2021. A total of 535 patients receiving the conventional method (CPJ) from January 2012 to June 2017 were used as a control group. PPH and POPF were defined according to the International Study Group of Pancreatic Surgery definition, but only PPH grade C was included for analysis. An IAA was defined as a collection of postoperative fluid managed by CT-guided drainage with documental culture. RESULTS There were no significant differences in the rate of POPF between the two groups (46.0% vs. 44.8%; p = 0.700). Furthermore, the percentages of bile in the drainage fluid in the TPJ and CPJ groups were 2.3% and 9.2%, respectively (p < 0.001). Lower proportions of PPH (0.9% vs. 6.5%; p < 0.001) and IAA (5.7% vs. 10.8%; p < 0.001) were observed for TPJ than for CPJ. On adjusted models, TPJ was significantly associated with a lower rate of PPH (odds ratio [OR] 0.132, 95% confidence interval [CI] 0.051-0.343; p < 0.001) and IAA (OR 0.514, 95% CI 0.349-0.758; p = 0.001) than CPJ. CONCLUSIONS TPJ is feasible to be performed and is associated with a similar rate of POPF but a lower percentage of concomitant bile in the drainage fluid and subsequent rates of PPH and IAA than CPJ.

Abstract
The choice of the most appropriate suture threads for pancreatic anastomoses may play an important role in reducing the incidence of post-operative pancreatic fistula (POPF). The literature on this topic is still not conclusive. The aim of this study was to analyze the mechanical characteristics of suture materials to find the best suture threads for pancreatic anastomoses. A single-axial electromagnetic actuation machine was used to obtain the stress–deformation relationship curves and to measure both the ultimate tensile strength (UTS) and the Young’s modulus at the 0–3% deformation range (E0–3) of four different suture materials (Poliglecaprone 25, Polydioxanone, Polyglactin 910, and Polypropylene) at baseline and after incubation in saline solution, bile, and pancreatic juice for 1, 3, and 7 days. Polydioxanone and Polypropylene showed stable values of UTS and E0–3 in all conditions. Polyglactin 910 presented significant UTS and E0–3 variations between different time intervals in all types of liquids analyzed. Poliglecaprone 25 lost half of its strength in all biological liquids analyzed but maintained low E0–3 values, which could reduce the risk of lacerations of soft tissues. These results suggest that Polydioxanone and Poliglecaprone 25 could be the best suture materials to use for pancreatic anastomoses. In vivo experiments will be organized to obtain further confirmations of this in vitro evidence.

Abstract
PURPOSE Although laparoscopic pancreaticoduodenectomy (LPD) is increasingly performed in high-volume centers, pancreaticojejunostomy (PJ) is still the most challenging procedure. Pancreatic anastomotic leakage remains a major complication after PD. Thus, various technical modifications regarding PJ, such as the Blumgart technique, have been attempted to simplify the procedure and minimize anastomotic leakage. Three-dimensional (3D) laparoscopic systems have been shown to be particularly helpful in performing difficult and precise tasks. We present a modified Blumgart anastomosis in 3D-LPD and investigate its clinical outcomes. METHODS A retrospective analysis of 100 patients who underwent 3D-LPD with modified Blumgart PJ from September 2018 to January 2020 was conducted. Data on the preoperative characteristics, operative outcomes, and postoperative characteristics of the patients were collected and analyzed. RESULTS The mean operative time and duration of PJ were 348.2 and 25.1 min, respectively. The mean estimated blood loss was 112 mL. The overall rate of postoperative complications over Clavien‒Dindo classification III was 18%. The incidence of clinically relevant postoperative pancreatic fistula was 11%. The median postoperative hospital stay was 14.2 days. Only one patient required reoperation (1%), and no patient died in the hospital or 90 days after the operation. High BMI, small main pancreatic duct diameter, and soft pancreatic consistency had a significant influence on the occurrence of CR-POPF. CONCLUSIONS The surgical outcome of 3D-LPD with modified Blumgart PJ seems to be comparable to other studies in terms of operation time, blood loss, hospital stay, and complication incidence. We consider the modified Blumgart technique in 3D-LPD to be novel, reliable, safe, and favorable for PJ in the PD procedure.

Abstract
Although conversion surgery has increasingly been performed for initially unresectable advanced pancreatic ductal adenocarcinoma (PDAC), the rate of conversion, including that for patients who do not undergo resection, remains unclear. Patients with PDAC who were treated between January 2013 and December 2018 were classified into three groups: resectable (R), borderline resectable (BR), and unresectable (UR). We analyzed patient outcomes, including the rate of surgical resection and survival, in each of these groups. In total, 211 patients (R, 118; BR, 22; UR, 81) were selected. Among them, 117 (99%), 18 (82%), and 15 (19%) patients in the R, BR, and UR groups, respectively, underwent surgical resection. R0 resection rates were 88, 78, and 67%, whereas median overall survival (OS) from treatment initiation were 31, 18, and 11 months (p < 0.0001) in the R, BR, and UR groups, respectively. In patients who underwent surgical resection, relapse-free survival (RFS) and OS were similar among the three groups (R vs. BR vs. UR; median RFS (months), 17 vs. 13 vs. 11, p = 0.249; median OS (months), 31 vs. 26 vs. 32, p = 0.742). Lymph node metastases and incomplete adjuvant chemotherapy were identified as independent prognostic factors for OS. Although the surgical resection rate was low, particularly in the BR and UR groups, the prognosis of patients who underwent surgical resection was similar irrespective of the initial resectability status.

Lengthened Efferent Limb in Braun Enteroenterostomy Reduces Delayed Gastric Emptying After Pancreaticoduodenectomy. World J Surg 2023; 47:1263-1270. [PMID: 36719447 DOI: 10.1007/s00268-023-06925-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/11/2023] [Indexed: 02/01/2023]
Abstract
BACKGROUND Delayed gastric emptying (DGE) is a common complication after pancreaticoduodenectomy (PD), but a method to prevent DGE has not been established. This study aims to demonstrate a novel technique utilizing a lengthened efferent limb in Billroth-II (B-II) reconstruction during PD and to evaluate the impact of the longer efferent limb on DGE occurrence. METHODS Patients who underwent PD with B-II reconstruction were divided into two groups: PDs with lengthened (50-60 cm) efferent limb (L group) and standard length (0-30 cm) efferent limb (S group). Postoperative outcomes were compared. DGE was defined and graded according to the International Study Group of Pancreatic Surgery criteria. RESULTS Among 283 consecutive patients who underwent PD from 2002 to 2021, 206 patients were included in this study. Patients who underwent Roux-en-Y reconstruction (n = 77) were excluded. Compared with the S group, the L group included older patients and those who underwent PD after 2016 (p = 0.025, < 0.001, respectively). D2 lymphadenectomy, antecolic route reconstruction, and Braun enteroenterostomy were performed more frequently in the L group (p = 0.040, < 0.001, < 0.001, respectively). The rate of DGE was significantly decreased to 6% in the L group, compared with 16% in the S group (p = 0.027), which might lead to a shorter hospital stay in the L group (p < 0.001). Multivariable analysis identified two factors as independent predictors for DGE: intraabdominal abscess [odds ratio (OR) 5.530, p = 0.008] and standard efferent limb length (OR 2.969, p = 0.047). CONCLUSION A lengthened efferent limb in Braun enteroenterostomy could reduce DGE after PD.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is often associated with significant morbidity and mortality after the Whipple operation. Patient-related factors associated with POPF include soft pancreatic texture and a small main pancreatic duct (MPD). The traditional duct-to-mucosa anastomosis was modified to be easily performed. The aim of the study was to evaluate the simplified pancreaticojejunostomy (PJ) method in the prevention of POPF after minimally invasive pancreaticoduodenectomy (PD). METHODS Ninety-eight patients who underwent laparoscopic pancreaticoduodenectomy (LPD) and robotic pancreaticoduodenectomy (RPD) with a simplified PJ procedure containing only two duct-to-mucosa sutures and four penetrating-sutures to anastomose the pancreatic parenchyma and jejunal seromuscular layer in our center were retrospectively studied. Demographics and clinical short-term safety were assessed. RESULTS All LPD and RPD procedures were successfully performed. The median time of PJ was 17 min, and the median blood loss was 60 mL, with only one patient requiring transfusion. Four patients (4.1%) suffered from clinically relevant POPF (CR-POPF), including four grade B cases and no grade C cases. For patients with an MPD diameter of 3 mm or less, POPF was noted in two (4%) of the fifty patients, with all cases being grade B. Of the patients with a soft pancreas, only two (4.5%) patients suffered from grade B POPF. One patient (1.0%) experienced a 90-day mortality. Neither the main pancreatic diameter nor pancreatic texture had an impact on postoperative outcomes. CONCLUSIONS Our technique is a simple, safe and efficient alternative to prevent POPF after LPD and RPD. This method is suitable for almost all pancreatic conditions, including cases with a small main pancreatic duct and soft pancreas, and has the potential to become the preferred procedure in low-volume pancreatic surgery centers. Our modified duct-to-mucosa PJ, which contains only two duct-to-mucosa sutures and four penetrating-sutures to anastomose the pancreatic parenchyma and jejunal seromuscular layer, is ideal for small MPD and soft pancreas when performing minimally invasive PD and has a low rate of POPF.

A Blumgart Anastomosis-Based Half-Invagination Pancreaticoenterostomy with Better Applicability to Laparoscopy and Lower Incidence of Pancreatic Leakage. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2023; 2023:6304047.

Abstract
Background The Blumgart anastomosis (BA) is one of the safest anastomoses for pancreatic stump reconstruction. The incidence of postoperative pancreatic fistula (POPF) and postoperative complications is low. However, how to make laparoscopic pancreaticoenterostomy easier and safer is still a topic to be discussed. Methods The data of patients who underwent laparoscopic pancreaticoduodenectomy (PD) from April 2014 to December 2019 were analyzed retrospectively. Results Half-invagination anastomosis was performed in 20 cases (HI group), and the Cattell-Warren anastomosis was carried out in 26 cases (CW group). The amount of intraoperative bleeding, operation time, and postoperative catheterization time in the HI group was significantly less than those in the CW group. Besides, the number of patients at the Clavien-Dindo grade III and above in the HI group was significantly less than that in the control group. Moreover, the incidence of POPF in the HI group was significantly lower than that in the CW group. Furthermore, fistula risk score (FRS) analysis showed that there was no high-risk group, and the highest risk in the medium-risk group was pancreatic leakage. In addition, the incidence of pancreatic leakage in the HI group and CW group was 7.7% and 46.67%, respectively, while the incidence of pancreatic leakage in the HI group was significantly lower than that in the CW group. Conclusions The half-invagination pancreaticoenterostomy based on the Blumgart anastomosis should have good applicability under laparoscopy and could effectively reduce the incidence of postoperative pancreatic leakage.

BACKGROUND Pancreaticojejunostomy (PJ) is the ''Achilles heel" of pancreaticoduodenectomy (PD) which affects perioperative as well as oncological outcomes. However, there is a lack of information about the superiority of the type of anastomosis in terms of overall morbidity and postoperative pancreatic fistula (POPF) after PD. Here, we compare the outcomes of modified Blumgart PJ with the dunking technique of PJ. METHODOLOGY A case-control study of a prospectively maintained database of 25 consecutive patients undergoing modified Blumgart PJ (study group) and 25 patients who underwent continuous dunking PJ (control group) between January 2018 to April 2021 was done. Between groups, comparisons were made for the duration of surgery, intraoperative blood loss, original fistula risk score, overall complications as graded by Clavien Dindo (CD), POPF, post pancreatectomy haemorrhage (PPH), delayed gastric emptying (DGE), and 30-day mortality at 95% confidence level. RESULTS Among 50 patients, 30 (60%) were male. The most common indication for PD was ampullary carcinoma (44% in the study group vs. 60% in the control group). The duration of surgery was approximately 41 minutes longer in the study group compared to the control (p = 0.02), while the intraoperative blood loss was similar between the two groups (496.00 ± 226.35 ml vs 508.00 ± 180.67 ml, p = 0.84). While there was no significant difference in mean fistula risk score between the two groups, the POPF (8% vs 32%, p = 0.03), PPH (0% vs 20%, p =0.02), and overall major complications (CD≥ III) according to CD Grading (12% vs 40%, p = 0.02) were significantly lower in the study group. Similarly, the duration of hospital stay in the study group was 4.64 days shorter than the control group (p = 0.001). However, there was no significant difference in the 30-day mortality between the two groups. CONCLUSIONS Modified Blumgart pancreaticojejunostomy has better perioperative outcomes in terms of procedure-specific complications like POPF, PPH, overall major postoperative complications, and duration of hospital stay.

A new fistula risk score using sarcopenic obesity and subcutaneous fat area for predicting postoperative pancreatic fistula after pancreaticoduodenectomy. JOURNAL OF HEPATO-BILIARY-PANCREATIC SCIENCES 2022. [PMID: 36448256 DOI: 10.1002/jhbp.1283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 10/31/2022] [Accepted: 11/04/2022] [Indexed: 12/03/2022]
Abstract
BACKGROUND/PURPOSE Postoperative pancreatic fistula (POPF) is a serious complication of pancreaticoduodenectomy and current predictors of POPF are inadequate. We developed a new fistula score to more accurately predict POPF. METHODS We retrospectively reviewed 169 patients who underwent pancreaticoduodenectomy between January 2010 and August 2021 at our institution and examined patients' risk factors according to the occurrence of grade B/C POPF. Muscle and fat were assessed on preoperative computed tomography images and cutoff values were determined by receiver operating characteristic curve analysis. RESULTS Grade B/C POPF occurred in 38 (22.5%) patients. Multivariate analysis of patients' risk factors revealed that sarcopenic obesity (odds ratio [OR] 2.94; p = .033), L3 subcutaneous fat area (SFA) ≥ 98.0 cm2 (OR 2.69; p = .049), and soft pancreatic texture (OR 27.5; p = .002) were independent risk factors of grade B/C POPF occurrence. In addition, a new fistula risk score based on these factors revealed that 63.6% of patients with high scores developed grade B/C POPF, while those with negligible or low scores did not. CONCLUSIONS A new fistula risk scoring system based on sarcopenic obesity, SFA, and pancreatic texture may accurately predict POFP.

Ligation of left gastric vein may cause delayed gastric emptying after pancreatoduodenectomy: a retrospective study. BMC Gastroenterol 2022; 22:398. [PMID: 36008761 PMCID: PMC9414412 DOI: 10.1186/s12876-022-02478-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2022] [Accepted: 08/19/2022] [Indexed: 11/10/2022] Open
Abstract
Background This study aimed to determine which running pattern of the left gastric vein (LGV) is most frequently ligated in subtotal stomach-preserving pancreatoduodenectomy (SSPPD) and how LGV ligation affects delayed gastric emptying (DGE) after SSPPD. Methods We retrospectively analysed 105 patients who underwent SSPPD between January 2016 and September 2021. We classified the running pattern of LGV as follows: type 1 runs dorsal to the common hepatic artery (CHA) or splenic artery (SpA) to join the portal vein (PV), type 2 runs dorsal to the CHA or SpA and joins the splenic vein, type 3 runs ventral to the CHA or SpA and joins the PV, and type 4 runs ventral to the CHA or SpA and joins the SpV. Univariate and multivariate analyses were used to identify differences between patients with and without DGE after SSPPD. Results Type 1 LGV running pattern was observed in 47 cases (44.8%), type 2 in 23 (21.9%), type 3 in 12 (11.4%), and type 4 in 23 (21.9%). The ligation rate was significantly higher in type 3 (75.0%) LGVs (p < 0.0001). Preoperative obstructive jaundice (p = 0.0306), LGV ligation (p < 0.0001), grade B or C pancreatic fistula (p = 0.0116), and sepsis (p = 0.0123) were risk factors for DGE in the univariate analysis. Multivariate analysis showed that LGV ligation was an independent risk factor for DGE (odds ratio: 13.60, 95% confidence interval: 3.80–48.68, p < 0.0001). Conclusion Type 3 LGVs are often ligated because they impede lymph node dissection; however, LGV preservation may reduce the occurrence of DGE after SSPPD.

Abstract
BACKGROUND Pancreatic fistula remains the biggest problem in pancreatic surgery. We have previously reported a new pancreatojejunostomy method using an inter-anastomosis drainage (IAD) suction tube with Blumgart anastomosis for drainage of the pancreatic juice leaking from the branched pancreatic ducts. This study aimed to evaluate the postoperative outcomes of our novel method, in pancreatojejunostomy and investigate the nature of the inter-anastomosis space between jejunal wall and pancreas parenchyma. METHODS This retrospectively study consist of 282 pancreatoduodenectomy cases, including 86 reconstructions via the Blumgart method plus IAD (B + IAD group) and 196 cases reconstructed using the Blumgart method alone (B group). Postoperative outcomes and the amylase value and the volume of the drainage fluids were compared between the two groups. The IAD tube was placed to collect amylase-rich fluid from the inter-anastomosis space during operative procedure between the jejunal wall and pancreatic stump. RESULTS The daily IAD drainage volume and the amylase level was significantly higher in patients with a soft pancreas (vs hard pancreas; 16.5 vs. 10.0 mL/day, p = 0.012; 90,900 vs. 1634 IU/L, p < 0.001, respectively). The mean amylase value of IAD collection in 86 cases of B + IAD group was 63,100 IU/L. The incidence of clinically relevant pancreatic fistula grade B and C (23.2% vs. 23.0%, p = 0.55) and the hospital stay was similar between the groups (median 17 vs. 18 days, p = 0.55). In 176 patients with soft pancreas, the incidence of pancreatic fistula grade B and C (33.3% vs. 35.3%, p = 0.67) and the hospital stay was also similar between the groups (median 22.5 vs. 21 days, p = 0.81). CONCLUSIONS Positive effect of the IAD method observed in the pilot cases was not reproduced in the current study. IAD tube objectively demonstrated the existence of amylase-rich discharge at the anastomosis site, and countermeasures to eliminate this liquid are highly desired for preventing pancreatic fistula, especially in patients with soft pancreatic texture. Trial registration Retrospectively registered.

Ann Gastroenterol Surg 2022; 6:880-886.

Abstract
Polyglycolic acid (PGA) felt has been used to prevent clinically relevant postoperative pancreatic fistula (CR‐POPF) after pancreaticoduodenectomy (PD). However, there has been no related research on Blumgart anastomosis. Therefore, this study aimed to investigate the practical significance of Blumgart anastomosis with our new method involving PGA felt to prevent CR‐POPF following PD. Data from 133 consecutive patients who underwent Blumgart anastomosis during PD between June 2015 and November 2021 were reviewed. We applied PGA felt to 35 of these patients starting from July 2020. Surgical outcomes were analyzed by propensity score matching. Thirty‐five (35.7%) of the 98 patients in the without‐PGA group were matched with an equal number from the with‐PGA group after adjusting for covariates. CR‐POPF was found in 17 patients (49%) in the without‐PGA group and two patients (6%) in the with‐PGA group (P < .001). The multivariate analysis results indicated that male sex, pancreatic duct size <3 mm, soft pancreatic texture, and nonuse of PGA were independently associated with CR‐POPF after PD. In conclusion, Blumgart anastomosis with our new penetrating method for PGA felt reduces the incidence of CR‐POPF after PD.

World J Clin Oncol 2022; 13:366-375. [PMID: 35662984 PMCID: PMC9153075 DOI: 10.5306/wjco.v13.i5.366] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 02/28/2022] [Accepted: 05/07/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Laparoscopic pancreaticoenteric anastomosis is one of the technically challenging steps of minimally invasive pancreaticoduodenectomy (PD), especially during the learning curve. Despite multiple randomized controlled trials and meta-analyses, the type of pancreatico-enteric anastomosis as a risk factor for post-pancreatectomy complications is debatable. Also, the ideal technique of pancreatic reconstruction during the learning curve of laparoscopic PD has not been well studied.
AIM To compare the short-term outcomes of modified binding pancreaticogastrostomy (PG) and Blumgart pancreaticojejunostomy (PJ) during learning curve of laparoscopic PD.
METHODS The first 25 patients with resectable pancreatic or periampullary tumors who underwent laparoscopic PD with modified binding PG or modified Blumgart PJ between January 2015 and May 2020 were retrospectively analyzed to compare perioperative outcomes during the same learning curve. A single layer of the full-thickness purse-string suture was placed around the posterior gastrotomy in the modified binding PG. In the modified Blumgart technique, only a single transpancreatic horizontal mattress suture was placed on either side of the pancreatic duct (total two sutures) to secure the pancreatic parenchyma to the jejunum. Also, on the ventral surface, the knot is tied on the jejunal wall without going through the pancreatic parenchyma. Post pancreatectomy complications are graded as per the International Study Group for Pancreatic Surgery criteria.
RESULTS During the study period, modified binding PG was performed in 27 patients and modified Blumgart PJ in 29 patients. The demographic and clinical parameters of the first 25 patients included in both groups were comparable. Lower end cholangiocarcinoma and ampullary adenocarcinoma were the primary indications for laparoscopic PD in both groups (32/50, 64%). The median operative time for pancreatic reconstruction was significantly lower in the binding PG group (42 vs 58 min, P = 0.01). The clinically relevant (Grade B/C) postoperative pancreatic fistula (POPF) was significantly more in the modified PJ group (28% vs 4%, P = 0.04). In contrast, intraluminal postpancreatectomy hemorrhage (PPH) was more in the binding PG group (32% vs 4%, P = 0.02). There was no significant difference in the incidence of delayed gastric emptying between the two groups.
CONCLUSION During the learning curve of laparoscopic PD, modified binding PG reduces POPF but is associated with increased intraluminal PPH compared to PJ using the modified Blumgart technique.

Abstract
BACKGROUND Pancreatic fistula is a life-threatening complication of pancreaticoduodenectomy. Omega-like duct-to-mucosa pancreatojejunostomy is a novel technique which helps reduce the risk of fistulation. This study aimed to compare early postoperative outcomes of omega-like and conventional pancreatojejunostomy. METHODS A retrospective single-centre cohort study comparing outcomes of adult patients who underwent open pancreatoduodenectomy with conventional (CDMP) or omega-like duct-to-mucosa pancreatojejunostomy (ODMP) between 1 January 2015 and 31 December 2019. The primary outcome measure was the pancreatic fistula rate. RESULTS 440 patients were included in this study of whom 233 underwent CDMP and 207 ODMP. The rate of clinically relevant pancreatic fistula (grade B/C) was significantly higher after CDMP than ODMP (18.5% vs. 10.6%, P = 0.021). 153 patients in CDMP group and 99 patients in ODMP group developed one or more complications (65.7% vs. 47.8%, P = 0.004). The average hospitalization expenses were numerically decreased in ODMP group, although this was not statistically significant (120,000 ± 42,000 [Chinese Yuan] vs. 100,000 ± 40,000 [Chinese Yuan] or 18,581 ± 6503 [United States Dollar] vs. 15,484 ± 6194 [United States Dollar], P = 0.402). CONCLUSION ODMP may reduce the incidence of pancreatic fistula and other early postoperative complications after pancreatoduodenectomy.

Abstract
BACKGROUND Pancreaticojejunostomy, an independent risk factor for pancreatic fistula, is the cause of several postoperative complications of pancreaticoduodenectomy. As suturing in minimally invasive surgery is difficult to perform, more simplified methods are needed to guarantee a safe pancreatic anastomosis. The concept of "biological healing" proposed in recent years has changed the conventional understanding of the anastomosis, which recommends rich blood supply, low tension, and loose sutures in the reconstruction of the pancreatic outflow tract. METHODS A literature search was conducted in PubMed for articles on pancreaticojejunostomy published between January 2014 and December 2021. After following a due selection process, several techniques developed in accordance with the concept of biological healing that were found suitable for minimally invasive surgery and their related clinical outcomes were described in this review. RESULTS The incidence of clinically relevant pancreatic fistula associated with the presented techniques did not exceed 15.9%, indicating superior results compared to Cattell-Warren double-layer duct-to-mucosa anastomosis (incidence: approximately 20%). The features and drawbacks of these approaches have been enumerated from the viewpoint of biological healing. CONCLUSIONS This review described several modified pancreaticojejunostomy techniques with the advantages of a simplified procedure and a lower incidence of pancreatic fistula. Surgeons can choose to apply them in clinical practice to improve patient prognosis.

[PMID: 34882986 DOI: 10.1002/jhbp.1095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Revised: 11/10/2021] [Accepted: 11/19/2021] [Indexed: 11/11/2022]
Abstract
BACKGROUNDS/PURPOSE The purpose of this study was to identify risk factors and establish a treatment strategy for clinical hepatico-jejunostomy stenosis defined with intrahepatic bile duct dilatation after pancreaticoduodenectomy. METHODS The 443 patients who underwent PD from April 2006 to December 2015 were analyzed. Clinical characteristics were compared between patients with and without clinical HJ stenosis, and risk factors for clinical HJ stenosis were analyzed. In addition, the treatment and clinical course of patients with clinical HJ stenosis were retrospectively reviewed. RESULTS Clinical HJ stenosis defined with intrahepatic bile duct dilatation was identified in 40 patients (9.0%). Multivariate analysis revealed that the independent risk factor for clinical HJ stenosis was the hepatic duct at surgery ≤ 8 mm. Endoscopic HJ stenosis was identified in 36 patients, and 31 patients were treated successfully with double balloon endoscopic retrograde cholangiography; 5 patients required re-anastomosis (n=3) and percutaneous transhepatic biliary drainage (n=2). Complete obstruction of HJ was found in 5 patients, and treatment with DB-ERC was successful in only one patient. CONCLUSION The independent risk factor for clinical HJ stenosis was hepatic duct diameter ≤8 mm. Most cases of endoscopic HJ stenosis were treated successfully with DB-ERC, except in patients with complete obstruction.

Hepatopancreatoduodenectomy With Delayed Division of the Pancreatic Parenchyma: A Novel Technique for Reducing Pancreatic Fistula. ANNALS OF SURGERY OPEN 2021; 2:e112. [PMID: 37637883 PMCID: PMC10455438 DOI: 10.1097/as9.0000000000000112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Accepted: 11/06/2021] [Indexed: 11/26/2022] Open
Abstract
Objectives To review our novel technique of hepatopancreatoduodenectomy (HPD) with delayed division of the pancreatic parenchyma (DDPP) for reducing postoperative pancreatic fistula (POPF). Background The high operative morbidity and mortality rates after HPD remains a major issue. One of the most troublesome complications is POPF, which might possibly be caused by peripancreatic saponification due to long interval between pancreas resection and reconstruction, as most surgeons prefer a caudocranial approach, performing pancreatoduodenectomy (PD) first and then hepatectomy (conventional HPD [C-HPD]). Methods A review of the patients undergoing C-HPD and HPD with DDPP was performed. Postoperative outcomes were compared. Multivariable analysis was conducted to evaluate the risk factors of POPF after HPD. Results One-hundred two patients comprised of 50 patients undergoing C-HPD and 52 patients undergoing HPD with DDPP. The interval between pancreas resection and reconstruction was significantly shorter in HPD with DDPP group than in C-HPD group (51 vs 263 minutes; P < 0.001). The incidence of POPF was significantly lower in HPD with DDPP group than in C-HPD group (32.7% vs 77.3%; P < 0.001). The postoperative hospital stay was shorter in patients undergoing HPD with DDPP than in those undergoing C-HPD (32 vs 45 days). A multivariate analysis revealed that body mass index >24 kg/m2 and conventional (PD first) procedure were significant risk factors for POPF after HPD. Conclusions A novel technique of HPD with DDPP is a simple procedure and the optimal treatment choice to reduce the risk of developing POPF after this extensive surgery.

Which is the best predictor of clinically relevant pancreatic fistula after pancreatectomy: drain fluid concentration or total amount of amylase? Ann Gastroenterol Surg 2021; 5:844-852. [PMID: 34755016 PMCID: PMC8560612 DOI: 10.1002/ags3.12471] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 04/23/2021] [Accepted: 04/25/2021] [Indexed: 01/04/2023] Open
Abstract
AIM Drain fluid amylase concentration (DFAC) has been reported as a predictor of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreatectomy. However, the clinical significance of measuring the total drain fluid amylase amount (DFAA) considering the daily drainage volume of CR-POPF remains unclear. METHODS Data from 216 consecutive patients who underwent pancreaticoduodenectomy (PD) (n = 126) or distal pancreatectomy (DP) (n = 90) between August 2014 and November 2020 were reviewed. All drains were closed but not suctioned. DFAA was calculated by multiplying the DFAC and daily drainage fluid volume. DFAC and DFAA were recorded on d 1 and 3 after pancreatectomy. The cutoff value of CR-POPF was determined using the receiver operating characteristic curve. RESULTS CR-POPF was found in 75 patients (35%) (PD: 30%, DP: 41%, P = .111); the mortality rate was zero. The cutoff value of DFAC-day 1 was 1757 U/L (sensitivity [SE]: 84%, specificity [SP]: 62%, and accuracy [AC]: 69%). The cutoff value of DFAA-day 1 was 139 U (SE: 71%, SP: 72%, and AC: 71%). The cutoff value of DFAC-day 3 was 1044 U/L (SE: 73%, SP: 79%, and AC: 78%). The cutoff value of DFAA-day 3 was 21 U (SE: 68%, SP: 72%, and AC: 70%). Multivariate analysis indicated that a nondilated pancreatic duct and high DFAC-day 3 were independently associated with CR-POPF after PD, indicating that a prolonged operative duration, massive blood loss, and high DFAC-day 3 are independently associated with CR-POPF after DP. CONCLUSION DFAC is more reliable than DFAA for predicting CR-POPF after both PD and DP.

Surg Today 2021; 52:580-586. [PMID: 34529132 DOI: 10.1007/s00595-021-02371-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Accepted: 07/08/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE The aim of this study was to elucidate the association between pancreatic fistula (PF) and the sequential changes in the perioperative exocrine function after pancreatectomy. METHODS The subjects were 96 patients who underwent a 13C-trioctanoin breath test before and 1 month after pancreatectomy, between 2006 and 2018. We retrospectively compared the pre- and postoperative fat absorption levels between patients with PF (PF group; n = 17) and without PF (non-PF group; n = 79) using the breath test. RESULTS The preoperative level of 13C-trioctanoin absorption (%dose/h) was comparable between the non-PF and PF groups (36.5 vs. 36.9). In the non-PF group, 13C-trioctanoin absorption was significantly decreased after surgery in comparison to the preoperative setting (post-operative 28.5; pre-operative 36.5; p < 0.0001), whereas these values were comparable (post-operative 36.9; pre-operative 34.5; p = 0.129) in the PF group. Moreover, postoperative absorption in the PF group was significantly better than that in the non-PF group (34.5 vs. 28.5%, p = 0.0003). The maximum drain amylase level was significantly higher in patients with a 13C-trioctanoin absorption level (%dose/h) of ≥ 30 in comparison to patients with levels of < 30 (2502 vs. 398 U/L, p = 0.001). CONCLUSION PF did not exacerbate the pancreatic exocrine function in the early postoperative period, and the acceleration or preservation of the exocrine function after surgery may be an important cause of PF.

Efficacy of laparoscopic-assisted pancreaticoduodenectomy in Vietnamese patients with periampullary of Vater malignancies: A single-institution prospective study. Ann Med Surg (Lond) 2021; 69:102742. [PMID: 34504691 PMCID: PMC8417344 DOI: 10.1016/j.amsu.2021.102742] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2021] [Revised: 08/13/2021] [Accepted: 08/15/2021] [Indexed: 11/24/2022] Open
Abstract
Introduction Minimally invasive pancreaticoduodenectomy is a technically complex technique, that is being used to treat periampullary malignancy. We provide our experience with laparoscopic-assisted pancreaticoduodenectomy (LAPD) with statistics on the outcomes of periampullary cancer patients. Material and method Thirty patients underwent surgery between June 1, 2016 and May 30, 2020, with 21 undergoing classical PD and 9 undergoing pylorus-preserving pancreaticoduodenectomy (PPPD). Prospectively gathered data on surgical outcomes and long-term oncological results are given. Results The median operative time was 277.5 min (range, 258.7–330 min), and the median intraoperative estimated blood loss was 319.5 mL (range, 241.2–425 mL). The rate of conversion to OPD, surgical reintervention, and mortality was 20%, 13.3%, and 10% respectively. Cumulative surgery-related morbidity was 33.4%, including bleeding (n = 4), severe POPF (n = 4), biliary fistula (n = 1), DGE (n = 2), and intestinal obstruction (n = 1). Pathologic diagnoses were AoV cancer (n = 23), distal CBD cancer (n = 4), PDAC (n = 2), and AoV NET (n = 1). The mean survival time of the LAPD group was 29.9 months. The long-term survival time of the N0 group was 36.8 months, which was significantly longer than that of the N1 group. The long-term survival times of stages I–B, II-A, and II-B were 36.9, 26.5, and 15.7 months, respectively (p = 0.016). Conclusion LAPD has a high rate of conversion to OPD, morbidity, and mortality. However, LPD is feasible technique for highly selected patients. Lymph node metastasis and stage of disease are the risk factors for long-term survival. Most of tumours that develop in the periampullary of the Vater region are malignant. Laparoscopic pancreaticoduodenectomy (LPD) remains the most challenging procedure in laparoscopic surgery with the rate of conversion to OPD, morbility, and mortality was 0–40%, 3.8%–50%, and 1.6%–8%, respectively. In the first 30 cases, LAPD has a high rate of complications, conversion to OPD, and mortality. However, LAPD is feasible method and can provide acceptable oncological results with careful patient selection. Experience, learning curve, and high-volume centre might have influenced the results.

Abstract
The technical complexity of robotic pancreaticoduodenectomy (RPD) and lack of technical surgical standardization have slowed its widespread application. RPD is only routinely performed in a few highly specialized centers. This study describes in detail the standard steps and core techniques of an experienced robotic center in China. We took advantage of our single experience to provide a step-by-step technique and surgical video of our RPD standardized procedure. We divided RPD into 18 key steps. Demographics and perioperative outcomes of consecutive 20 patients who underwent the RPD standardized procedure were analyzed. For the 20 consecutive patients, the mean operative time was 253.6 min, and the median estimated blood loss was 210.0 mL. One patient required conversion to laparotomy due to the need for PV reconstruction. One patient had grade 3 complication. The median postoperative hospital stay was 11.0 days. No 90-day mortality was observed. By simplifying and optimizing the surgical techniques, the RPD procedure can be standardized and modeled to improve feasibility and repeatability.

Abstract
BACKGROUND Several advantages and pitfalls have been related to externalized trans-anastomotic stents (ETS) after pancreaticoduodenectomy. The purpose of this study was to investigate the effect of an ETS effect in a risk-stratified setting. METHODS Data from patients at either intermediate- or high-risk for postoperative pancreatic fistula (POPF) following pancreaticoduodenectomy were prospectively analyzed from January 2016 to December 2019. Outcomes included POPF rate, mean complication burden (ACB), and complications related to ETS malfunction. RESULTS A total of 540 patients met the inclusion criteria. Following an intention-to-treat analysis, there was no difference in terms of POPF and the ACB in the intermediate (22 vs.29%, p = 0.148; 0.38 vs.0.24, p = 0.082) and high-risk categories (58 vs.37%, p = 0.103; 0.33 vs.0.33, p = 0.478) comparing PJ to PJ-ETS. Excluding patients experiencing ETS malfunction (n = 45, 22%), ETS was associated with a significantly reduced ACB in the intermediate-risk (0.38 vs.0.26, p = 0.009) and POPF rate in the high-risk category (58 vs.32%, p = 0.033). In patients with ETS malfunction an increased rate of severe morbidity (Clavien-Dindo ≥ III, 33 vs.19%, p = 0.044) was observed as compared to patients with functioning ETS. CONCLUSION ETS provides crucial advantages for prevention and mitigation of POPF depending on risk setting and its correct functioning. ETS malfunction is not uncommon and increases morbidity. Improving ETS design and fixing technique might lead to better outcomes.

Abstract
PURPOSE The systemic immune-inflammation index (SII) is a new marker, defined as the platelet count × neutrophil-to-lymphocyte ratio. This study evaluates the SII as a prognostic marker for the overall survival (OS) of patients who underwent pancreatoduodenectomy (PD) for distal cholangiocarcinoma (DCC). METHODS One hundred and forty patients who underwent PD for DCC between September, 2002 and December, 2015 at our hospital were divided into a low SII (SII < 1450) group and a high SII (SII ≥ 1450) group. We compared the clinicopathological characteristics and OS of the two groups retrospectively and used multivariate analyses to identify the prognostic factors for OS. RESULTS The low and high SII groups comprised 119 and 21 patients, respectively. OS was better in the low SII group than in the high SII group, with median survival times of 81 and 26 months, respectively (p < 0.001). Multivariate analyses revealed that portal vein resection (hazard ratio [HR], 9.58; p < 0.001), SII ≥ 1450 (HR, 2.05; p = 0.041), microscopic venous invasion (HR, 2.04; p = 0.005), and pN1 (HR, 1.73; p = 0.034) were independently associated with poor survival. CONCLUSION The SII may be useful for predicting the long-term survival of patients with DCC after PD.

Abstract
BACKGROUND Postoperative pancreatic fistula is a main cause of fatal complications post-pancreatoduodenectomy. However, no universally accepted drainage management exists for clinically relevant postoperative pancreatic fistulas. We retrospectively evaluated cases in which drain contrast imaging was used to determine its utility in identifying clinically relevant postoperative pancreatic fistulas post-pancreatoduodenectomy. METHODS Between January 2014 and December 2018, 209 consecutive patients who underwent pancreatoduodenectomy in our institute were retrospectively analyzed. Drain monitoring with contrast imaging was performed in 47 of the cases. We classified drain contrast type into three categories and evaluated postoperative outcome in each group: (1) fistulous tract group-only the fistula was contrasted; (2) fluid collection group - fluid collection connected to the drain fistula; and (3) pancreatico-anastomotic fistula group-fistula connected to the digestive tract. RESULTS The durations of postoperative hospital stay and drainage were significantly shorter in the fistulous tract group than in the fluid collection group (31 vs. 46 days, p = 0.0026; and 12 vs. 38 days, p < 0.0001, respectively). The cost and number of drain exchanges were significantly lower in the fistulous tract group than in the fluid collection group ($163.6 vs. 467.5, p < 0.0001; and 1 vs. 5.5, p < 0.0001, respectively). Notably, no patient had grade C postoperative pancreatic fistula. CONCLUSION Classification of prophylactic drain contrast type can aid in predicting outcomes of clinically relevant postoperative pancreatic fistulas and optimizing drainage management.

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
Objective Microsurgery using conventional optical microscopes or surgical loupes features a limited field of view and imposes a serious strain on surgeons especially during long surgeries. Here we advocate the micro- and macro-borderless surgery (MMBS) using a novel high-resolution (4K) three-dimensional (3D) video system. This study aimed to confirm the applicability of this concept in several surgical procedures. Methods We evaluated the possible use and efficacy of MMBS in the following experiments in porcine subjects. Experiment 1 (non-inferiority test) consisted of dissection and anastomosis of carotid artery, portal vein, proper hepatic artery, and pancreatoduodenectomy with surgical loupe versus MMBS. Experiment 2 (feasibility test) consisted of intra-abdominal and intra-thoracic smaller arteries anastomosed by MMBS as a pre-clinical setting. Experiment 3 (challenge on new surgery) consisted of orthotopic liver transplantation of the graft from a donor after circulatory death maintained by machine perfusion. Circulation of the cardiac sheet with a vascular bed in experiment 2 and liver graft during preservation in experiment 3 was evaluated with indocyanine green fluorescence imaging equipped with this system. Results Every procedure was completed by MMBS. The operator and assistants could share the same field of view in heads-up status. The focal depth was deep enough not to be disturbed by pulsing blood vessels or respiratory movement. The tissue circulation could be evaluated using fluorescence imaging of this system. Conclusions MMBS using the novel system is applicable to various surgeries and valuable for both fine surgical procedures and high-level surgical education.

Wrapping double-mattress anastomosis for pancreaticojejunostomy in minimally invasive pancreaticoduodenectomy can significantly reduce postoperative pancreatic fistula rate compared with conventional pancreaticojejunostomy in open surgery: An analysis of a propensity score-matched sample. Surg Oncol 2021; 38:101577. [PMID: 33887674 DOI: 10.1016/j.suronc.2021.101577] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 03/29/2021] [Accepted: 04/01/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND Minimally invasive pancreaticoduodenectomy (MIPD), including laparoscopic pancreaticoduodenectomy (LPD) and robotic pancreaticoduodenectomy (RPD), is technically demanding because of pancreaticojejunostomy (PJ). Postoperative pancreatic fistula (POPF) is the most serious complication of MIPD and open pancreaticoduodenectomy (OPD). Contrary to expectations, conventional PJ in MIPD did not improve POPF rate and length of hospital stay. High POPF rates are attributed to technical issues encountered during MIPD, which include motion restriction and insufficient water tightness. Therefore, we developed wrapping double-mattress anastomosis, the Kiguchi method, which is a novel PJ technique that can improve MIPD. Herein, we describe the Kiguchi method for PJ in MIPD and compare the outcomes between this technique and conventional PJ in OPD. METHODS The current retrospective study included 83 patients in whom the complete obstruction of the main pancreatic duct by pancreatic tumors was absent on preoperative imaging. This research was performed from September 2016 to August 2020 at Fujita Health University Hospital. All patients were evaluated as having a soft pancreatic texture, which is the most important factor associated with POPF development. Briefly, 50 patients underwent OPD with conventional PJ (OPD group). Meanwhile, 33 patients, including 15 and 18 who had LPD and RPD, respectively, underwent MIPD using the Kiguchi method (MIPD group). After a 1:1 propensity score matching, 30 patients in the OPD group were matched to 30 patients in the MIPD group. RESULTS The patients' preoperative data did not differ. The grade B/C POPF rate was significantly lower in the MIPD group than in the OPD group (6.7% vs 40.0%, p = 0.002). The MIPD group had a significantly shorter median length of hospital stay than the OPD group (24 vs 30 days, p = 0.004). CONCLUSION The novel Kiguchi method in MIPD significantly reduced the POPF rate in patients without complete obstruction of the main pancreatic duct.

Abstract
BACKGROUND Pancreatic fistulas remain a significant concern after pancreatectomy owing to the associated high risk of mortality and high costs. It is not possible to perform preoperative risk stratification for all patients. This study aimed to evaluate the usefulness of the measurement of portal vein (PV) distance as a predictive indicator of pancreatic fistula development after pancreatoduodenectomy and compare it with the usefulness of other indicators such as body mass index (BMI), and abdominal fat area. METHODS Patient characteristics, preoperative laboratory data, radiographic findings, and their association with pancreatic fistula development after pancreatoduodenectomy were analyzed for 157 patients who underwent resection during 2011-2017. Clinically relevant postoperative pancreatic fistulas (CR-POPF) were defined as Grade B or C fistulas based on the International Study Group of Pancreatic Surgery (ISGPS) 2016 consensus. RESULTS CR-POPF developed in 38 patients (24.2%). Multivariate logistic regression indicated that PV distance and BMI were potential candidates for predictive models for pancreatic fistula development, and small pancreatic duct diameter, diabetes mellitus development, and pathology of non-pancreatic cancers were independent factors for CR-POPF. When comparing the two risk models (PV distance- and BMI-based models), the PV distance-derived risk model was compatible to the BMI-based stratification models (area under the curve 0.831 vs. 0.830). CONCLUSIONS PV distance was confirmed to be a useful risk predictor for CR-POPF. This research highlighted the efficacy of abdominal thickness measurement, which is simple and easily applicable in the clinical setting.

Abstract
BACKGROUND The superiority of Blumgart anastomosis (BA) over non-BA duct to mucosa (non-BA DtoM) still remains under debate. METHODS We performed a systematic search of studies comparing BA to non-BA DtoM. The primary endpoint was CR-POPF. Postoperative morbidity and mortality, post-pancreatectomy hemorrhage (PPH), delayed gastric emptying (DGE), reoperation rate, and length of stay (LOS) were evaluated as secondary endpoints. The meta-analysis was carried out using random effect. The results were reported as odds ratio (OR), risk difference (RD), weighted mean difference (WMD), and number needed to treat (NNT). RESULTS Twelve papers involving 2368 patients: 1075 BA and 1193 non-BA DtoM were included. Regarding the primary endpoint, BA was superior to non-BA DtoM (RD = 0.10; 95% CI: -0.16 to -0.04; NNT = 9). The multivariate ORs' meta-analysis confirmed BA's protective role (OR 0.26; 95% CI: 0.09 to 0.79). BA was superior to DtoM regarding overall morbidity (RD = -0.10; 95% CI: -0.18 to -0.02; NNT = 25), PPH (RD = -0.03; 95% CI -0.06 to -0.01; NNT = 33), and LOS (- 4.2 days; -7.1 to -1.2 95% CI). CONCLUSION BA seems to be superior to non-BA DtoM in avoiding CR-POPF.

Abstract
PURPOSE This study aimed to establish a reliable criterion for early drain removal after pancreaticoduodenectomy (PD) based on predictive factors of clinically relevant postoperative pancreatic fistula (CR-POPF) available on postoperative day 3 (POD3). METHODS A total of 300 consecutive patients who underwent PD with pancreaticojejunostomy at our hospital from 2011 to 2015 were analyzed retrospectively. CR-POPF was defined as POPF grade B or C according to the definition by ISGPF. Clinicopathological factors available on or before POD3 were analyzed to identify predictors of CR-POPF. Using obtained predictors, we developed a criterion for no CR-POPF and internally validated its relevance in 100 consecutive patients. RESULTS The incidence rates of CR-POPF, severe complications (Clavien-Dindo ≥ grade IIIa), and postoperative mortality were 35%, 9.6%, and 0.3%, respectively. Multivariate analysis showed that drain amylase (d-AMY) levels ≥ 350 IU/l on POD3, C-reactive protein (CRP) levels ≥ 14 mg/dl on POD3, preoperative endoscopic retrograde biliary drainage, and no portal vein resection were significant predictors of CR-POPF. Using the strongest predictors (i.e., d-AMY and CRP), we established a criterion for no CR-POPF: d-AMY levels < 350 IU/l and CRP levels < 14 mg/dl on POD3. The incidence rates of CR-POPF were 6%, 38%, and 88% in patients who fulfilled both of (n = 149), each of (n = 74), and none of (n = 77) the two factors, respectively. In the internal validation cohort, the positive predictive value of CR-POPF was 89%. CONCLUSIONS A simple two-factor criterion available on POD3 after PD has a reliable predictive ability. In patients who fulfill this criterion, early drain removal is considered safe.

Abstract
OBJECTIVE Postoperative intra-abdominal infection is one of the most serious complications after pancreatic resection. In this article, we investigated the relationship between serum lactate level and postoperative infection, to suggest a new predictor of potential infection risk after pancreatectomy. METHODS A retrospective analysis of 156 patients who underwent pancreatic surgery and admitted in the intensive care unit for recovery after surgery between August 2017 and August 2019 was performed. RESULTS The basic characteristics, preoperative information, pathological diagnoses, surgical methods, and intraoperative situations of patients in the postoperative intra-abdominal infection group (n = 52) and non-infection group (n = 104) showed no significant differences. With the same postoperative treatments and results of fluid balance, blood pressure maintenance, and laboratory tests, postoperative serum lactate level increased much higher in the infection group than non-infection group (P < 0.001), while the base excess level declined much lower (P = 0.002). Patients in the infection group needed more time to elute lactate (P < 0.001), and stayed longer in the intensive care unit after surgery (P = 0.007). The overall postoperative complications were certainly more in the infection group (P < 0.001), resulting in a longer hospitalization time (P < 0.001). CONCLUSIONS When patients recovered smoothly from anesthesia with a stable hemodynamics situation and normal results of laboratory tests, abnormally high serum lactate level could be a predictor of postoperative intra-abdominal infection after pancreatic resection.

Abstract
PURPOSE An organ/space surgical site infection reportedly develops in 20% of patients who undergo pancreaticoduodenectomy (PD). The present study aimed to identify the predictors for developing severe infectious complications after PD. METHODS We retrospectively reviewed the records of 115 consecutive patients who underwent PD at Ehime University Hospital between January 2013 and January 2020. Severe infectious complications were defined as Clavien-Dindo classification grade ≥ III postoperative complications related to bacterial or fungal infections, including clinically relevant postoperative pancreatic fistula (CR-POPF). The patient characteristics, blood chemistry data, body composition data and operative data were evaluated as potential predictors of severe infectious complications. We also evaluated the erythrocyte indices, such as the mean corpuscular hemoglobin, the mean corpuscular hemoglobin concentration, and the mean corpuscular volume (MCV). RESULTS Among 115 patients, 25 (21.7%) developed severe infectious complications, which included 20 (17.4%) cases of CR-POPF. According to multivariate analyses, MCV > 97.4fL, C-reactive protein (CRP) > 1.2 mg/dL and diameter of main pancreatic duct < 5 mm were independent predictors of severe infectious complications (odds ratio, 13.891, 7.356 and 4.676, respectively, 95% confidence interval, 3.457-55.815, 1.868-28.964 and 1.391-15.716, respectively). CONCLUSION Preoperative high MCV/CRP values and a small main pancreatic duct are predictive factors associated with severe infectious complications after PD.

Abstract
BACKGROUND The Blumgart anastomosis is a method of pancreaticojejunostomy after pancreaticoduodenectomy (PD) which combines the principle of duct-to-mucosa anastomosis with an invagination technique of the pancreas. METHODS Retrospective study involving consecutive patients who underwent pancreaticoduodenectomy for pancreatic head cancer. Data predictive of pancreatic fistula and postoperative outcomes were collected. The patients were divided into three groups and were compared based on the type of pancreatic anastomosis performed: Blumgart anastomosis (BA), duct-to-mucosa anastomosis (DtoM), and invagination pancreaticojejunostomy (PJ). The primary endpoint was to determine the occurrence of clinically relevant postoperative pancreatic fistula (CR-POPF). The secondary endpoints were to determine whether postoperative pancreatic fistula grade C (POPF C) and/or severe complications occurred as well as to determine the reoperation rate and 30- and 90-day mortality. A propensity score matching analysis was used. RESULTS Using propensity score matching (PSM), the occurrence of CR-POPF was not significantly different between the BA (21.6%) and the other pancreatic anastomoses (all 31.1%, DtoM = 27.0%; PJ = 35.1%). However, the BA significantly reduced (1) severe complications (0 versus 35.1%; P < 0.001) and 90-day mortality (0% versus 12.2%; P = 0.028) with respect to all anastomoses; (2) severe complications (0% versus 29.7%; P < 0.001), POPF grade C (0% versus 16.2%; P = 0.025), and reoperation (2.7% versus 16.2%; P = 0.056) with respect to DtoM; and (3) severe complications (0% versus 40.5%; P < 0.001) and 90-day mortality (0% versus 13.5%; P = 0.054) with respect to PJ. CONCLUSIONS Applying the PSM analysis for the first time, the present study seemed to suggest that the BA succeeded in minimizing severe complications after PD.

Impact of Preoperative Occult-Bacterial Translocation on Surgical Site Infection in Patients Undergoing Pancreatoduodenectomy. J Am Coll Surg 2020; 232:298-306. [PMID: 33316423 DOI: 10.1016/j.jamcollsurg.2020.12.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 11/05/2020] [Accepted: 12/01/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Occult-bacterial translocation (O-BT) has been reported as the condition in which microorganisms are detected in blood or lymph nodes by a highly sensitive method. However, the clinical impact of preoperative O-BT on postoperative complication is unclear. STUDY DESIGN A prospective observational study with patients undergoing pancreatoduodenectomy for periampullary diseases was conducted. Blood samples were collected immediately after induction of anesthesia. The status of O-BT was investigated using bacterium-specific ribosomal RNA-targeted reverse transcriptase-quantitative polymerase chain reaction (RT-qPCR). The impact of O-BT on surgical site infection (SSI) was analyzed. RESULTS A total of 155 patients were included. The positive rate in preoperative blood samples detected by RT-qPCR was significantly higher than that obtained by the culture method (32 of 155 vs 4 of 155, p < 0.001). Preoperative blood samples were contaminated with 1.0 to 19.2 bacterial cells/mL in positive patients, and 30 of the 41 detected microorganisms were obligate anaerobes. No differences in preoperative factors were observed between patients with positive and negative RT-qPCR results. The incidence of any SSI was significantly higher in patients with contaminated preoperative blood (≥1.2 bacterial cells/mL) than in other patients (14 of 27 vs 35 of 128, p = 0.013). Multivariable analysis indicated that contaminated preoperative blood was identified as one of the independent risk factors for SSI (odds ratio 2.71, 95% CI 1.04 to 7.24, p = 0.041). CONCLUSIONS O-BT, predominantly with obligate anaerobes, was commonly observed in preoperative blood samples. In addition to the previously known risk factors, O-BT may be one of the risk factors for SSI after pancreatoduodenectomy.

Abstract
Introduction Delayed gastric emptying (DGE) remains an important problem after pancreaticoduodenectomy (PD). There is a lack of effective treatments for early recovery of oral dietary intake. Rikkunshito (RKT), a Japanese herbal medicine, has been gaining attention as a facilitator of gastric emptying. We evaluated the effects of RKT on DGE after PD. Methods In this prospective, randomized, open-labeled study, patients were randomly allocated before PD in a 1:1 ratio to the RKT group or the control group that received no additional treatment. The RKT group received 2.5 g of RKT three times daily (7.5 g/day) from postoperative day (POD) 1 to POD 21. The primary endpoint was the incidence of DGE. Secondary endpoints were short-term postoperative outcomes including oral dietary intake volume and perioperative changes in levels of the hormones ghrelin and leptin. Patients were observed until hospital discharge. Results Twenty-six patients in each group (n = 52) completed the protocol treatment and were included in the analysis set. There were no statistically significant differences in basic characteristics and operative factors. The overall incidence of DGE was not statistically different between the RKT and control groups (30.8% vs 30.8%, p>0.9999). There were no statistically significant differences in the amount of postoperative oral dietary intake represented by total dietary intake (TDI) up to POD 14 and POD 21, complications, and length of hospital stay. No adverse events related to this study were observed. In the RKT group, total ghrelin and acyl-ghrelin were significantly upregulated and leptin was significantly downregulated earlier than in the control group. Conclusion RKT treatment from POD 1 to 21 did not reduce the incidence of DGE and had no clinically beneficial effect on short-term postoperative outcomes irrespective of changes in hormone levels.

Abstract
Background Postoperative pancreatic fistula (POPF) is one of the most serious complications after pancreaticoduodenectomy (PD). Various factors have been reported as POPF risks, but the most serious of these is soft pancreas. To reduce POPF occurrences, many changes to the PD process have been proposed. This study evaluates short-term results of anastomosis technique for PD. Methods In total, 123 patients with soft pancreases who had undergone PD at Yamanashi University between January 2012 and August 2020 were retrospectively analyzed. We divided these patients into two groups depending on the time PD was performed: a conventional group (n = 67) and a modified group (n = 56). Results The rate of clinically relevant POPF was significantly lower in the modified group than that in the conventional group (5.4% vs 22.4%, p value < 0.001), with there being only one case of POPF in the modified group. There were no cases of POPF-related hemorrhaging in the modified group. On the third day after the operation, the amylase levels in the drainage fluid for the modified group became less than half (1696 vs 650 U/L). Multivariate analysis showed that the modified method was the independent predictors to prevent clinical POPF (p value = 0.002). Conclusions Our novel anastomosis technique for pancreatojejunostomy reduced POPF in PD, especially in cases where the patient had a soft pancreas.

Blumgart anastomosis reduces the incidence of pancreatic fistula after pancreaticoduodenectomy: a systematic review and meta-analysis. Sci Rep 2020; 10:17896. [PMID: 33087777 PMCID: PMC7578105 DOI: 10.1038/s41598-020-74812-4] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2020] [Accepted: 10/07/2020] [Indexed: 02/05/2023] Open
Abstract
Postoperative pancreatic fistula (POPF) is the most serious complication after pancreaticoduodenectomy (PD). Recently, Blumgart anastomosis (BA) has been found to have some advantages in terms of decreasing POPF compared with other pancreaticojejunostomy (PJ) using either the duct-to-mucosa or invagination approach. Therefore, the aim of this study was to examine the safety and effectiveness of BA versus non-Blumgart anastomosis after PD. The PubMed, EMBASE, Web of Science and the Cochrane Central Library were systematically searched for studies published from January 2000 to March 2020. One RCT and ten retrospective comparative studies were included with 2412 patients, of whom 1155 (47.9%) underwent BA and 1257 (52.1%) underwent non-Blumgart anastomosis. BA was associated with significantly lower rates of grade B/C POPF (OR 0.38, 0.22 to 0.65; P = 0.004) than non-Blumgart anastomosis. Additionally, in the subgroup analysis, the grade B/C POPF was also reduced in BA group than the Kakita anastomosis group. There was no significant difference regarding grade B/C POPF in terms of soft pancreatic texture between the BA and non-Blumgart anastomosis groups. In conclusion, BA after PD was associated with a decreased risk of grade B/C POPF. Therefore, BA seems to be a valuable PJ to reduce POPF comparing with non-Blumgart anastomosis.
