Abstract
BACKGROUND Surgical reconstruction is a crucial stage in various surgeries, including pancreaticoduodenectomy, as it can significantly affect the surgical results. The objective was to design a suture force feedback (SFF) device that can precisely measure the suture force during surgical closures. Afterward, the device was used to train junior surgeons in surgical closure techniques. METHODS The SFF was used to capture the suture force data of experienced surgeons. This data was utilized to train and assess junior surgeons. The SFF device had 2 tactile-based force sensors that measured the applied force. Whenever the applied force was not within the optimal force range, the device provided feedback to the surgeon. A workshop was conducted to train junior surgeons in surgical closure techniques to improve their suturing skills. RESULTS Thirty-seven junior surgeons were enrolled in this training, of whom only 24 completed the 30-day training program. The pre-assessment results revealed that the force exerted by junior surgeons during suture knot-tying was uneven compared with that of the experienced surgeons, with a significant difference in the force exerted per knot throw (P = 0.005. Before the training program, junior surgeons applied a force of 3.89 ± 0.43 N, which was more than twice the force applied by experienced surgeons (1.75 ± 0.12 N). However, after completing the 30-day training program, their force improved to 2.35 ± 0.13 N. CONCLUSIONS The SFF device was shown to be an encouraging training tool for improving the surgical closure dexterity and technique of the participating junior surgeons.

Analysis of factors influencing pancreatic fistula after minimally invasive pancreaticoduodenectomy and establishment of a new prediction model for clinically relevant pancreatic fistula. Surg Endosc 2024; 38:2622-2631. [PMID: 38499780 PMCID: PMC11078842 DOI: 10.1007/s00464-024-10770-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2023] [Accepted: 02/22/2024] [Indexed: 03/20/2024]
Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is the most prevalent complications following minimally invasive pancreaticoduodenectomy (MIPD). Only one model related to MIPD exists, and previous POPF scoring prediction methods are based on open pancreaticoduodenectomy patients. Our objectives are to determine the variables that may increase the probability of pancreatic fistula following MIPD and to develop and validate a POPF predictive risk model. METHODS Data from 432 patients who underwent MIPD between July 2015 and May 2022 were retrospectively collected. A nomogram prediction model was created using multivariate logistic regression analysis to evaluate independent factors for POPF in patients undergoing MIPD in the modeling cohort. The area under the curve (AUC) of the receiver operating characteristic curve (ROC) and the calibration curve were used to verify the nomogram prediction model internally and externally within the modeling cohort and the verification cohort. RESULTS Multivariate logistic regression analysis showed that body mass index (BMI), albumin, triglycerides, pancreatic duct diameter, pathological diagnosis and intraoperative bleeding were independent variables for POPF. On the basis of this information, a model for the prediction of risks associated with POPF was developed. In accordance with the ROC analysis, the modeling cohort's AUC was 0.819 (95% CI 0.747-0.891), the internal validation cohort's AUC was 0.830 (95% CI 0.747-0.912), and the external validation cohort's AUC was 0.793 (95% CI 0.671-0.915). Based on the calibration curve, the estimated values of POPF have a high degree of concordance with the actual values that were measured. CONCLUSIONS This model for predicting the probability of pancreatic fistula following MIPD has strong predictive capacity and can provide a trustworthy predictive method for the early screening of high-risk patients with pancreatic fistula after MIPD and timely clinical intervention.

Abstract
Objective: To introduce laparoscopic neo-pancreaticogastrostomy (neo-PG) and investigate its application potential in total laparoscopic pancreaticoduodenectomy (TLPD). Materials and Methods: We performed a single-center prospective single-arm trial to evaluate the feasibility and safety of neo-PG for its initial application in TLPD. The first 50 patients who were operated by a single surgeon and who underwent TLPD with neo-PG at our institution were recruited. The pre/intra/postoperation data were collected and analyzed. Results: Twenty-nine male patients and 21 female patients from May 2022 to March 2023 were included. The mean operation time was 272.60 ± 47.30 minutes. The median PG time was 16 (15, 23) minutes. Six patients had delayed gastric emptying (DGE), and all underwent standard LPD. None of the patients had Grade B/C postoperative pancreatic fistula (POPF) or postoperative hemorrhage, or underwent reoperation. The median length of post-LPD hospital stay was 6 (6, 8) days. None of the patients died within 90 days after surgery. Nineteen cases were pathologically classified as pancreatic lesion, 6 cases as bile duct lesion, 18 cases as duodenal lesion, and 7 cases as ampullary lesion. Conclusion: The laparoscopic neo-PG is a simple, safe, and feasible pancreatic anastomosis that can be applied in TLPD. Pylorus-preserving LPD may decrease DGE rate. Further studies involving more surgeons are warranted to prove that our new technique may terminate POPF in TLPD.

Abstract
BACKGROUND Among the safest procedures for anastomosis in pancreaticoduodenectomy, Blumgart pancreaticojejunostomy is associated with low rates of postoperative pancreatic fistula (POPF) and postoperative complications. However, this technique is difficult to perform during laparoscopic pancreaticoduodenectomy (LPD). This study presents a modified Blumgart method using a homemade crochet needle to facilitate laparoscopic pancreaticojejunostomy and evaluates its safety and reliability. METHODS From February 2019 to October 2022, 96 LPD surgeries with the new technique were performed by the same surgeons in the Second Affiliated Hospital of Zhejiang University School of Medicine. The operative details (operative time, pancreaticojejunostomy time, POPF rate, postoperative complication rate, mortality rate) were analyzed along with clinical and pathological indicators (pancreatic duct diameter, pancreatic texture, and histopathological findings). RESULTS There were 54 men and 42 women with a mean age of 63.38 ± 10.41 years. The intraoperative bleeding volume, operative time and postoperative length of hospital stay were 198.43 ± 132.97 mL, 445.30 ± 87.05 min and 13.68 ± 4.02 days, respectively. The operation time of pancreaticojejunostomy was 66.28 ± 10.17 min. Clinically relevant POPFs (grades B and C) occurred in 14.6% of patients. Only one patient had postoperative abdominal hemorrhage and was cured after reoperation. There were no operative or in-hospital deaths. With our proposed modification, the pancreatic duct and jejunal orifice are aligned correctly during duct-to-mucosa (DTM) after the application of external traction through the homemade crochet needle. The space between the posterior wall of pancreatic remnant and jejunal loop can be exposed by adjusting the tension of the external threads, which can facilitate DTM. CONCLUSIONS A modified Blumgart method using a homemade crochet needle could be technically feasible and safe during LPD. A randomized control trial is needed to confirm these findings.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is one of the most serious complications after pancreaticoduodenectomy (PD), and the choice of pancreaticojejunostomy (PJ) is considered a key factor affecting the occurrence of POPF. Numerous anastomotic methods and their modifications have been proposed, and there is no method that can completely avoid the occurrence of POPF. Based on our team's experience in pancreatic surgery and a review of relevant literature, we describe a novel invagination procedure for PJ using double purse string sutures, which has resulted in favourable outcomes. AIM To describe the precise procedural steps, technical details and clinical efficacy of the novel invagination procedure for PJ. METHODS This study adopted a single-arm retrospective cohort study methodology, involving a total of 65 consecutive patients who underwent PD with the novel invagination procedure for PJ, including the placement of a pancreatic stent, closure of the residual pancreatic end, and two layers of purse-string suturing. Baseline data included age, sex, body mass index (BMI), pancreatic texture, pancreatic duct diameter, operation time, and blood loss. Clinical outcomes included the operation time, blood loss, and incidence of POPF, postoperative haemorrhage, delayed gastric emptying, postoperative pulmonary infection, postoperative abdominal infection, and postoperative pulmonary infection. RESULTS The mean age of the patients was 59.12 (± 8.08) years. Forty males and 25 females were included, and the mean BMI was 21.61 kg/m2 (± 2.74). A total of 41.53% of patients had a pancreatic duct diameter of 3 mm or less. The mean operation time was 263.83 min (± 59.46), and the mean blood loss volume was 318.4 mL (± 163.50). Following the surgical intervention, only three patients showed grade B POPF (4.62%), while no patients showed grade C POPF. Five patients (5/65, 7.69%) were diagnosed with postoperative haemorrhage. Six patients (6/65, 9.23%) experienced delayed gastric emptying. Four patients (4/65, 6.15%) developed postoperative pulmonary infection, while an equivalent number (4/65, 6.15%) exhibited postoperative abdominal infection. Additionally, two patients (2/65, 3.08%) experienced postoperative pulmonary infection. CONCLUSION The novel invagination technique for PJ is straightforward, yields significant outcomes, and has proven to be safe and feasible for clinical application.

Abstract
BACKGROUND Mortality rates after pancreaticoduodenectomy (PD) have significantly decreased in specialized centers. However, postoperative morbidity, particularly delayed gastric emptying (DGE), remains the most frequent complication following PD. AIM To identify risk factors associated with DGE after the PD procedure. METHODS In this retrospective, cross-sectional study, clinical data were collected from 114 patients who underwent PD between January 2015 and June 2018. Demographic factors, pre- and perioperative characteristics, and surgical complications were assessed. Univariate and multivariate analyses were performed to identify risk factors for post-PD DGE. RESULTS The study included 66 males (57.9%) and 48 females (42.1%), aged 33-83 years (mean: 62.5), with a male-to-female ratio of approximately 1.4:1. There were 63 cases (55.3%) of PD and 51 cases (44.7%) of pylorus-preserving pancreatoduodenectomy. Among the 114 patients who underwent PD, 33 (28.9%) developed postoperative DGE. Univariate analysis revealed significant differences in four of the 14 clinical indexes observed: pylorus preservation, retrocolonic anastomosis, postoperative abdominal complications, and early postoperative albumin (ALB). Logistic regression analysis further identified postoperative abdominal complications [odds ratio (OR) = 4.768, P = 0.002], preoperative systemic diseases (OR = 2.516, P = 0.049), and early postoperative ALB (OR = 1.195, P = 0.003) as significant risk factors. CONCLUSION Postoperative severe abdominal complications, preoperative systemic diseases, and early postoperative ALB are identified as risk factors for post-PD DGE.

Abstract
BACKGROUND Postoperative pancreatic fistula (POPF) is the most serious complication and the main reason for morbidity and mortality after pancreaticoduodenectomy (PD). Currently, there exists no flawless pancreaticojejunal anastomosis approach. We presents a new approach called Chen's penetrating-suture technique for pancreaticojejunostomy (PPJ), which involves end-to-side pancreaticojejunostomy by suture penetrating the full-thickness of the pancreas and jejunum, and evaluates its safety and efficacy. METHODS To assess this new approach, between May 2006 and July 2018, 193 consecutive patients who accepted the new Chen's Penetrating-Suture technique after a PD were enrolled in this study. Postoperative morbidity and mortality were evaluated. RESULTS All cases recovered well after PD. The median operative time was 256 (range 208-352) min, with a median time of 12 (range 8-25) min for performing pancreaticojejunostomy. Postoperative morbidity was 19.7% (38/193) and mortality was zero. The POPF rate was 4.7% (9/193) for Grade A, 1.0% (2/193) for Grade B, and no Grade C cases and one urinary tract infection. CONCLUSION PPJ is a simple, safe, and reliable technique with ideal postoperative clinical results.

J Pers Med 2023; 13:jpm13050858. [PMID: 37241028 DOI: 10.3390/jpm13050858] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2023] [Revised: 05/16/2023] [Accepted: 05/19/2023] [Indexed: 05/28/2023] Open
Abstract
(1) Background: The jejunum is primarily used for distal pancreatic stump anastomoses after central pancreatectomy (CP). The study aimed to compare duct-to-mucosa (WJ) and distal pancreatic invagination into jejunum anastomoses (PJ) after CP. (2) Methods: All patients with CP and jejunal anastomoses (between 1 January 2002 and 31 December 2022) were retrospectively assessed and compared. (3) Results: 29 CP were analyzed: WJ-12 patients (41.4%) and PJ-17 patients (58.6%). The operative time was significantly higher in the WJ vs. PJ group of patients (195 min vs. 140 min, p = 0.012). Statistically higher rates of patients within the high-risk fistula group were observed in the PJ vs. WJ group (52.9% vs. 0%, p = 0.003). However, no differences were observed between the groups regarding the overall, severe, and specific postpancreatectomy morbidity rates (p values ≥ 0.170). (4) Conclusions: The WJ and PJ anastomoses after CP were comparable in terms of morbidity rates. However, a PJ anastomosis appeared to fit better for patients with high-risk fistula scores. Thus, a personalized, patient-adapted technique for the distal pancreatic stump anastomosis with the jejunum after CP should be considered. At the same time, future research should explore gastric anastomoses' emerging role.

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.

Preoperative risk assessment for postoperative pancreatic fistula (POPF): Image-based calculation of duct-to-parenchyma (D/P) ratio and an Alignment of Duct and Mucosa (ADAM) anastomosis may lead to a low POPF rate—results from 386 patients. Front Surg 2022; 9:1039191.

Abstract
BackgroundPostoperative pancreatic fistula (POPF) is the most critical complication after pancreatoduodenectomy (PD). Preoperative identification of high-risk patients and optimal pancreatic reconstruction technique can be a way to reduce postoperative complications.MethodsA series of 386 patients underwent PD over a 10-year period (2009–2019). On routinely performed preoperative computed tomography (CT) images, the ventro-dorsal diameters of duct (D) and parenchyma (P) were measured in the cutting plane at the superior mesenteric vein. Then, the ratio of both values was calculated (D/P ratio) Double-layer pancreatojejunostomy with alignment of duct and mucosa (ADAM) by two monofilament threads (MFT) was performed in 359 patients and pancreatogastrostomy (PG) in 27 patients. The incidence of POPF was diagnosed according to the International Study Group for Pancreatic Fistula criteria.ResultsThe overall rate of POPF was 21% (n = 80), and the rate of clinically relevant type B/C fistulas 6.5% (n = 25). A D/P ratio of <0.2 was significantly associated with type B/C fistula (11%, p < 0.01). In low-risk patients (D/P ratio >0.2), type B/C fistula occurred only in 2%, and in high-risk patients (D/P ratio <0.2) in 9%. ADAM anastomosis was performed safely by two different surgeons. A PG anastomosis had double-digit POPF rates in all groups.ConclusionPreoperative CT imaging with D/P measurement may predict the risk of POPF development. A cut off D/P ratio of <0.2 was significantly associated with clinical relevant POPF. ADAM anastomosis may be an option for pancreatojejunostomy. However, preoperative knowledge of the D/P ratio could guide decision-making for primary pancreatectomy when pancreatic reconstruction is critical.

Abstract
BACKGROUND Postoperative pancreatic fistula (PF) is a serious life-threatening complication after pancreaticoduodenectomy (PD). Our research aimed to develop a machine learning (ML)-aided model for PF risk stratification.
AIM To develop an ML-aided model for PF risk stratification.
METHODS We retrospectively collected 618 patients who underwent PD from two tertiary medical centers between January 2012 and August 2021. We used an ML algorithm to build predictive models, and subject prediction index, that is, decision curve analysis, area under operating characteristic curve (AUC) and clinical impact curve to assess the predictive efficiency of each model.
RESULTS A total of 29 variables were used to build the ML predictive model. Among them, the best predictive model was random forest classifier (RFC), the AUC was [0.897, 95% confidence interval (CI): 0.370–1.424], while the AUC of the artificial neural network, eXtreme gradient boosting, support vector machine, and decision tree were between 0.726 (95%CI: 0.191–1.261) and 0.882 (95%CI: 0.321–1.443).
CONCLUSION Fluctuating serological inflammatory markers and prognostic nutritional index can be used to predict postoperative PF.

Abstract
Objective: To explore the surgical effect of three-dimensional (3D) image reconstruction technology in pancreatoduodenectomy. Methods: The clinical records of 47 cases who underwent pancreatoduodenectomy between January 2018 and December 2019 at the department of hepatobiliary surgery of the General Hospital of Ningxia Medical University were retrospectively examined, including 23 males and 24 females, with an average age of 55.00 ± 10.06 years. All patients underwent enhanced computed tomography (CT), and the 3D images were reconstructed by uploading the CT imaging data. The pre-operation evaluation and treatment strategy were planned according to CT imaging and 3D data, respectively. The change of treatment strategy based on 3D evaluation, actual surgical procedure, tumor volume measured by 3D model, actual tumor volume, variants of hepatic artery, operation time, intraoperative blood loss, post-operation hospital stay and post-operation complications was recorded. Results: The treatment strategies were changed after 3D visualization in 10 (21.3%) out of 47 patients because of blood vessel and organ invasion by tumor. The surgical procedure was changed in three cases, and the surgical procedure was optimized and improved in seven cases. All surgical plans based on 3D visualization technology were matched with the actual surgical procedures. Tumor volume measured by 3D model was 19.69 ± 23.47 mL, post-operation actual tumor volume was 17.07 ± 20.29 mL, with no significant difference between them (t = 0.54, p = 0.59). Pearson’s correlation analysis showed statistical significance (r = 0.766, p = 0.00). The average operation time was 4.85 ± 1.75 h, median blood loss volume was 447.05 (50–5000) mL, and post-operation hospital stay was 26.13 ± 11.13 days. Six cases had pancreatic fistula, two cases had biliary leakage, and four cases had delayed gastric emptying. Ascites and pleural effusion was observed in three cases. Conclusions: 3D visualization technology can offer a precise and individualized surgical plan before operation, which might improve the safety of pancreatoduodenectomy, and has application value in preoperative planning.

Abstract
BACKGROUND Postoperative pancreatic fistula is a common and serious complication following pancreaticoduodenectomy. Duct-to-mucosa pancreaticojejunostomy has been used in many centers to reconstruct pancreatic digestive continuity following pancreatoduodenectomy, however, its efficacy and safety are uncertain. OBJECTIVES To assess the benefits and harms of duct-to-mucosa pancreaticojejunostomy versus other types of pancreaticojejunostomy for the reconstruction of pancreatic digestive continuity in participants undergoing pancreaticoduodenectomy, and to compare the effects of different duct-to-mucosa pancreaticojejunostomy techniques. SEARCH METHODS We searched the Cochrane Library (2021, Issue 1), MEDLINE (1966 to 9 January 2021), Embase (1988 to 9 January 2021), and Science Citation Index Expanded (1982 to 9 January 2021). SELECTION CRITERIA We included all randomized controlled trials (RCTs) that compared duct-to-mucosa pancreaticojejunostomy with other types of pancreaticojejunostomy (e.g. invagination pancreaticojejunostomy, binding pancreaticojejunostomy) in participants undergoing pancreaticoduodenectomy. We also included RCTs that compared different types of duct-to-mucosa pancreaticojejunostomy in participants undergoing pancreaticoduodenectomy. DATA COLLECTION AND ANALYSIS Two review authors independently identified the studies for inclusion, collected the data, and assessed the risk of bias. We performed the meta-analyses using Review Manager 5. We calculated the risk ratio (RR) for dichotomous outcomes and the mean difference (MD) for continuous outcomes with 95% confidence intervals (CIs). For all analyses, we used the random-effects model. We used the Cochrane RoB 1 tool to assess the risk of bias. We used GRADE to assess the certainty of the evidence for all outcomes. MAIN RESULTS We included 11 RCTs involving a total of 1696 participants in the review. One RCT was a dual-center study; the other 10 RCTs were single-center studies conducted in: China (4 studies); Japan (2 studies); USA (1 study); Egypt (1 study); Germany (1 study); India (1 study); and Italy (1 study). The mean age of participants ranged from 54 to 68 years. All RCTs were at high risk of bias. Duct-to-mucosa versus any other type of pancreaticojejunostomy We included 10 RCTs involving 1472 participants comparing duct-to-mucosa pancreaticojejunostomy with invagination pancreaticojejunostomy: 732 participants were randomized to the duct-to-mucosa group, and 740 participants were randomized to the invagination group after pancreaticoduodenectomy. Comparing the two techniques, the evidence is very uncertain for the rate of postoperative pancreatic fistula (grade B or C; RR 1.45, 95% CI 0.64 to 3.26; 7 studies, 1122 participants; very low-certainty evidence), postoperative mortality (RR 0.77, 95% CI 0.39 to 1.49; 10 studies, 1472 participants; very low-certainty evidence), rate of surgical reintervention (RR 1.12, 95% CI 0.65 to 1.95; 10 studies, 1472 participants; very low-certainty evidence), rate of postoperative bleeding (RR 0.85, 95% CI 0.51 to 1.42; 9 studies, 1275 participants; very low-certainty evidence), overall rate of surgical complications (RR 1.12, 95% CI 0.92 to 1.36; 5 studies, 750 participants; very low-certainty evidence), and length of hospital stay (MD -0.41 days, 95% CI -1.87 to 1.04; 4 studies, 658 participants; very low-certainty evidence). The studies did not report adverse events or quality of life outcomes. One type of duct-to-mucosa pancreaticojejunostomy versus a different type of duct-to-mucosa pancreaticojejunostomy We included one RCT involving 224 participants comparing duct-to-mucosa pancreaticojejunostomy using the modified Blumgart technique with duct-to-mucosa pancreaticojejunostomy using the traditional interrupted technique: 112 participants were randomized to the modified Blumgart group, and 112 participants were randomized to the traditional interrupted group after pancreaticoduodenectomy. Comparing the two techniques, the evidence is very uncertain for the rate of postoperative pancreatic fistula (grade B or C; RR 1.51, 95% CI 0.61 to 3.75; 1 study, 210 participants; very low-certainty evidence), postoperative mortality (there were no deaths in either group; 1 study, 210 participants; very low-certainty evidence), rate of surgical reintervention (RR 1.93, 95% CI 0.18 to 20.91; 1 study, 210 participants; very low-certainty evidence), rate of postoperative bleeding (RR 2.89, 95% CI 0.12 to 70.11; 1 study, 210 participants; very low-certainty evidence), overall rate of surgical complications (RR 1.10, 95% CI 0.80 to 1.51; 1 study, 210 participants; very low-certainty evidence), and length of hospital stay (15 days versus 15 days; 1 study, 210 participants; very low-certainty evidence). The study did not report adverse events or quality of life outcomes. AUTHORS' CONCLUSIONS The evidence is very uncertain about the effects of duct-to-mucosa pancreaticojejunostomy compared to invagination pancreaticojejunostomy on any of the outcomes, including rate of postoperative pancreatic fistula (grade B or C), postoperative mortality, rate of surgical reintervention, rate of postoperative bleeding, overall rate of surgical complications, and length of hospital stay. The evidence is also very uncertain whether duct-to-mucosa pancreaticojejunostomy using the modified Blumgart technique is superior, equivalent or inferior to duct-to-mucosa pancreaticojejunostomy using the traditional interrupted technique. None of the studies reported adverse events or quality of life outcomes.

Pancreaticojejunostomy Conducive to Biological Healing in Minimally Invasive Pancreaticoduodenectomy. J Gastrointest Surg 2022; 26:1967-1981. [PMID: 35546220 PMCID: PMC9489565 DOI: 10.1007/s11605-022-05339-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2022] [Accepted: 04/10/2022] [Indexed: 01/31/2023]
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.

Abstract
BACKGROUND While the best technique for pancreatic anastomosis during Whipple's procedure remains controversial, laparoscopic pancreaticoduodenectomy (LPD) has been rapidly increasing in popularity. Because of their feasibility and reliability, new pancreatic anastomosis techniques may have vital roles when adapted for LPD. Here, we describe a new pancreaticojejunostomy (PJ) technique using three sutures (termed the "three sutures" PJ technique), which facilitates pancreatic anastomosis during total LPD. METHODS A total of 149 patients who underwent LPD using the "three sutures" PJ technique at three hospitals were included in this study (81 patients at Guangdong Provincial People's Hospital [GDPH], 60 patients at Sun Yat-Sen Memorial Hospital [SMH], and 8 patients at Affiliated Hospital of Guangdong Medical University [AHGMU]). Data on the demographic characteristics, operative outcomes, and postoperative results (pancreatic fistula rate, mortality rate, and length of hospital stay) of these patients were collected and analyzed. RESULTS A surgical video showing the details of the "three sutures" PJ method was included. The mean operation times at GDPH, SMH, and AHGMU were 4.08 ± 0.99 h, 4.65 ± 1.53 h, and 4.67 ± 0.64 h, respectively, and the average PJ times were 17.96 ± 3.49 min, 18.19 ± 2.63 min, and 22.5 ± 3.96 min, respectively. The numbers of grade B pancreatic fistulas were 9 (11.11%), 2 (3.33%), and 1 (12.50%), respectively, and two patients had grade C fistulas, one each at GDPH and SMH. The numbers of clinically relevant postoperative pancreatic fistula (CR-POPF) were 10 (12.35%), 3 (5.00%), and 1 (12.50%) in each center, respectively. The overall rate of CR-POPF was 9.40% (14/149) among patients of all three centers. The perioperative mortality rate was 0%. CONCLUSIONS The "three sutures" PJ technique for total LPD is a safe and reliable method, with a low risk of pancreatic fistula, short anastomosis time, and steep learning curve.

Abstract
BACKGROUND Prophylactic somatostatin to reduce the incidence of clinically relevant postoperative pancreatic fistula after pancreaticoduodenectomy remains controversial. We assessed the preventive efficacy of somatostatin on clinically relevant postoperative pancreatic fistula in intermediate-risk patients who underwent pancreaticoduodenectomy at pancreatic centres in China. METHODS In this multicentre, prospective, randomised controlled trial, we used the updated postoperative pancreatic fistula classification criteria and cases were confirmed by an independent data monitoring committee to improve comparability between centres. The primary endpoint was the rate of clinically relevant postoperative pancreatic fistula within 30 days after pancreaticoduodenectomy. RESULTS Eligible patients (randomised, n = 205; final analysis, n = 199) were randomised to receive postoperative intravenous somatostatin (250 μg/h over 120 h; n = 99) or conventional therapy (n = 100). The primary endpoint was significantly lower in the somatostatin vs control group (n = 13 vs n = 25; 13% vs 25%, P = 0.032). There were no significant differences for biochemical leak (P = 0.289), biliary fistula (P = 0.986), abdominal infection (P = 0.829), chylous fistula (P = 0.748), late postoperative haemorrhage (P = 0.237), mean length of hospital stay (P = 0.512), medical costs (P = 0.917), reoperation rate (P > 0.99), or 30 days' readmission rate (P = 0.361). The somatostatin group had a higher rate of delayed gastric emptying vs control (n = 33 vs n = 21; 33% vs 21%, P = 0.050). CONCLUSIONS Prophylactic somatostatin treatment reduced clinically relevant postoperative pancreatic fistula in intermediate-risk patients after pancreaticoduodenectomy.

Abstract
BACKGROUND The mortality rate following pancreaticoduodenectomy (PD) has been decreasing over the past few years; nonetheless, the morbidity rate remains elevated. The most common complications after PD are post-operative pancreatic fistula (POPF) and delayed gastric emptying (DGE) syndrome. The issue as to which is the best reconstruction method for the treatment of the pancreatic remnant after PD is still a matter of debate. The aim of this study was to retrospectively analyze the morbidity rate in 100 consecutive PD reconstructed with Wirsung-Pancreato-Gastro-Anastomosis (WPGA), performed by a single surgeon applying a personal modification of the pancreatic reconstruction technique. METHODS During an 8-year period (May 2012 to March 2020), 100 consecutive patients underwent PD reconstructed with WPGA. The series included 57 males and 43 females (M/F 1.32), with a mean age of 68 (range 41-86) years. The 90-day morbidity and mortality were retrospectively analyzed. Additionally, a systematic review was conducted, comparing our technique with the existing literature on the topic. RESULTS We observed eight cases of clinically relevant POPF (8%), three cases of "primary" DGE (3%) and four patients suffering "secondary" DGE. The surgical morbidity and mortality rate were 26% and 6%, respectively. The median hospital stay was 13.6 days. The systematic review of the literature confirmed the originality of our modified technique for Wirsung-Pancreato-Gastro-Anastomosis. CONCLUSIONS Our modified double-layer WPGA is associated with a very low incidence of POPF and DGE. Also, the technique avoids the risk of acute hemorrhage of the pancreatic parenchyma.

Abstract
OBJECTIVES To develop a radiomics model and a combined model for preoperative prediction of clinically relevant postoperative pancreatic fistula (CR-POPF) in patients undergoing pancreaticoduodenectomy and to compare the predictive performance of the two models with the traditional Fistula Risk Score system. METHODS A total of 250 patients who underwent pancreaticoduodenectomy (PD) with preoperative computed tomography (CT) were divided into a training set (n = 175) and validation set (n = 75). The pancreatic area was automatically segmented on the portal venous phase CT images using a 3D U-Net segmentation model. A radiomics model was developed using radiomics features extracted from the volume of interest (VOI) and a combined model was developed using radiomics features, demographic information and radiological features. The FRS was also used to predict POPF. The predictive performance of the prediction models was assessed using receiver operating characteristic (ROC) curves, calibration curves and decision curve analysis (DCA). RESULTS Eleven and 18 features were extracted for the radiomics model and combined model, respectively. The combined model showed excellent predictive value, with an AUC of 0.871 (95 %CI 0.816,0.926) and 0.869 (95 %CI 0.779,0.958) in the training cohort and validation cohort, respectively. Calibration curves and DCA showed that the combined model outperformed the traditional FRS system and radiomics model. CONCLUSION The combined model exhibited excellent predictive performance and outperformed the traditional FRS system and radiomics model in the preoperative prediction of CR-POPF.

Abstract
INTRODUCTION Laparoscopic pancreatic reconstruction is a challenging procedure and is considered the Achilles' heel of laparoscopic pancreatectomy. Multiple techniques of laparoscopic pancreatic reconstruction have been reported, but the optimal technique remains unclear. AREAS COVERED This paper provides a brief introduction to the developmental status and major related complications of laparoscopic pancreatic reconstruction. We reviewed all published literature on the technology of laparoscopic pancreatic reconstruction within the last 5 years and herein discuss the advantages and disadvantages of different reconstruction methods. We also discuss several details of different reconstruction techniques in terms of their significance to the operation and complications. EXPERT OPINION No individual method of laparoscopic pancreatic reconstruction is considered optimal for all conditions. The reconstruction strategy should be based on the surgeon's proficiency with laparoscopic technology and the patient's individual risk factors. Personalized methods of pancreatic reconstruction may more effectively reduce morbidity and mortality.
