Pancreaticogastrostomy versus Pancreaticojejunostomy and the Proposal of a New Postoperative Pancreatic Fistula Risk Score. J Clin Med 2023; 12:6193. [PMID: 37834836 PMCID: PMC10573877 DOI: 10.3390/jcm12196193] [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: 08/12/2023] [Revised: 09/07/2023] [Accepted: 09/20/2023] [Indexed: 10/15/2023] Open
Abstract
Despite the substantial decrease in mortality rates following a pancreaticoduodenectomy to less than 5%, morbidity rates remain significant, reaching even 73%. Postoperative pancreatic fistula is one of the most frequent major complications and is significantly associated with other complications, including patient death. Currently, there is no consensus regarding the ideal type of pancreatic anastomosis, as the question of the choice between a pancreaticogastrostomy and pancreaticojejunostomy is still open. Furthermore, worldwide implementation of an ideal pancreatic fistula risk prediction score is missing. Our study found several significant predictive factors for the postoperative occurrence of fistulas, such as the soft consistency of the pancreas, non-dilated Wirsung duct, important intraoperative blood loss, other perioperative complications, preoperative patient hypoalbuminemia, and patient weight loss. Our study also revealed that for patients who exhibit fistula risk factors, pancreaticogastrostomy demonstrates a significantly lower pancreatic fistula rate than pancreaticojejunostomy. The occurrence of pancreatic fistulas has been significantly associated with the development of other postoperative major complications, and patient death. As the current pancreatic fistula risk scores proposed by various authors have not been consensually validated, we propose a simple, easy-to-use, and sensitive score for the risk prediction of postoperative pancreatic fistula occurrence based on important predictors from statistical analyses that have also been found to be significant by most of the reported studies. The new pancreatic fistula risk score proposed by us could be extremely useful for improved therapeutic management of cephalic pancreaticoduodenectomy patients.

Abstract
INTRODUCTION Hepatic artery anomalies (HAA) may have an impact on surgical and oncological outcomes of patients undergoing pancreaticoduodenectomy (PD). METHODS Patients who underwent PD at our institution between July 2015 and January 2020 were retrospectively reviewed and classified into two groups: group 1, with presence of HAA, and group 2, with no HAA. A weighted logistic regression model was employed to assess the association between HAA and postoperative complications, and to assess the association between HAA and R status in patients with pancreatic cancer. RESULTS 502 patients were considered for analysis, with 75 (15%) of them in group 1. They had either an accessory (n = 28, 40.8%) or replaced (n = 26, 36.6%) right hepatic artery. Most patients underwent surgery for a malignancy (n = 451; 90%); among them, vascular resection was performed in 69 cases (15%). The presence of a HAA was reported at preoperative imaging only in 4 cases (5%) and the aberrant vessel was preserved in 72% of patients. At weighted multivariable logistic regression analysis, HAA were not associated to higher odds of morbidity (odds ratio [OR]: 0.753, 95% confidence interval [CI]: 0.543-1.043) nor to R1 status in case of pancreatic cancer (OR: 1.583, 95% CI: 0.979-2.561). CONCLUSION At our institution, the presence of HAA does not have an impact on postoperative outcomes or affects oncological clearance after PD. Hospitals', surgeons', volume and systematic review of preoperative imaging are all factors that help reduce possible adverse events.

Abstract
Knowledge of anatomical variations of the hepatic artery from its origin to intrahepatic segmentation is of utmost importance for planning upper abdominal surgeries including liver transplantation, pancreatoduodenectomy, and biliary reconstruction. The origin and branching pattern of the hepatic artery was thoroughly described by the classification of Michels and Hiatt. Some rare variations of the hepatic artery were classified by Kobayashi and Koops. By the use of the multidetector computed tomography (MDCT) technique, the branching pattern of the hepatic artery can be visualized quite accurately. Unawareness of these arterial variations may lead to intraoperative injuries such as necrosis, abscess, and failure of the liver and pancreas. The origin and course of the aberrant hepatic arteries are crucial in the surgical planning of carcinoma of the head of the pancreas and hepatobiliary surgeries. In liver transplant surgeries, to minimize intraoperative bleeding complications and postoperative thrombosis, exact anatomy of the branching of the hepatic artery, its variations and intrahepatic course is of utmost importance. This review discusses variations in the anatomy of the hepatic artery from its origin to branching by the use of advanced imaging techniques and its effect on the liver, pancreatic, biliary and gastric surgeries.

Abstract
Abstract
Background
During pancreaticoduodenectomy proper dissection of local vessels is required. Normal coeliac and hepatic arterial anatomy can be found in only 50–70% of individuals. Good knowledge about aberrant vascular anatomies is necessary to avoid unnecessary complications.
Case presentation
An elderly gentleman presented to us with history of jaundice. Periampullary carcinoma with abnormal right and left hepatic artery morphology was discovered after a contrast enhanced computerized tomography scan.
Conclusion
Despite the anomalous origin and anterior course of replaced right hepatic artery, Classical pancreatoduodenectomy with preservation of replaced right hepatic artery and regional lymphadenectomy with no major intra and post-operative problems was conducted by superior mesenteric artery first approach. Prior to major hepato-pancreatobiliary surgery, a thorough examination of a contrast enhanced computerized tomography scan is required to understand vascular anatomy, recognize anomalous vessels, and understand their significance. Nevertheless, if the abnormal vessel anatomy like replaced right hepatic artery are identified during surgery, a careful dissection of the anomalous vessel is essential to identify all vascular relationships and avoid irreversible injury.

Abstract
The anatomical structure of the pancreaticoduodenal region is complex and closely related to the surrounding vessels. A variant of the hepatic artery, which is not a rare finding during pancreatic surgery, is prone to intraoperative injury. Inadvertent injury to the hepatic artery may affect liver perfusion, resulting in necrosis, liver abscess, and even liver failure. The preoperative identification of hepatic artery variations, detailed planning of the surgical approach, careful intraoperative dissection, and proper management of the damaged artery are important for preventing hepatic hypoperfusion. Nevertheless, despite the potential risks, planned artery resection has become acceptable in carefully selected patients. Arterial reconstruction is sometimes essential to prevent postoperative ischemic complications and can be performed using various methods. The complexity of procedures such as pancreatectomy with en bloc celiac axis resection may be mitigated by the presence of an aberrant right hepatic artery or a common hepatic artery originating from the superior mesenteric artery. Here, we comprehensively reviewed the anatomical basis of hepatic artery variation, its incidence, and its effect on the surgical and oncological outcomes after pancreatic resection. In addition, we provide recommendations for the prevention and management of hepatic artery injury and liver hypoperfusion. Overall, the hepatic artery variant may not worsen surgical and oncological outcomes if it is accurately identified pre-operatively and appropriately managed intraoperatively.

Abstract
INTRODUCTION Evaluation of anatomical variations is important in pancreatoduodenectomy (PD) because an arterial anomaly is a risk factor for morbidity. Herein, we report a rare case of PD for lower bile duct cancer in which celiac axis stenosis and a replaced common hepatic artery (rCHA) coexisted. PRESENTATION OF CASE An 84-year-old woman presented with epigastric pain. She was diagnosed with a lower bile duct cancer and underwent PD. Preoperative computed tomography showed celiac axis stenosis, and the deformed celiac artery had a "hooked appearance," suggesting compression by the median arcuate ligament (MAL). The rCHA branched from the superior mesenteric artery. The gastroduodenal artery (GDA) diverged from the rCHA, forming a developed arterial arcade of the pancreatic head. There was an oncological safety margin between the rCHA and common bile duct; however, a part of the collateral artery was close to the common bile duct. Therefore, we planned to preserve the rCHA and resect the GDA to form collateral circulation. The MAL was divided and we evaluated the blood flow of the left upper abdominal organs using indocyanine green fluorescence imaging with a near-infrared camera system. We considered that perfusion of organs was preserved, and PD was performed without vessel reconstruction. No ischemic complication occurred in the postoperative course. DISCUSSION The coexistence of these arterial anomalies made the procedure of PD more complicated. CONCLUSION Precise preoperative diagnosis of arterial anomalies is necessary to avoid postoperative complications that may be induced by intraoperative arterial injury and organ ischemia.

Abstract
Backgrounds/Aims The soft texture of the pancreas parenchyma may influence the incidence of pancreatic leakage after pancreaticoduodenectomy (PD). One possible method to assess pancreatic texture and atrophy, is via computed tomography (CT) scan of the abdomen. The purpose of our study was to evaluate the relation between the preoperative CT scan and the incidence of pancreatic fistula after PD. Methods A retrospective single-center study including patients who underwent PD for a benign and malignant tumor of the periampullary region between the years 2000 and 2016. Demographic and imaging data were analysed and a correlation with the post-operative leak was evaluated. Results Pancreatic leak was documented in 34 out of 154 (22.1%) patients. All the leakage cases occurred in the preserved pancreas group (33.1% of the total preserved pancreas group alone). No leak was documented in the atrophic pancreas group. This difference between the two groups was found to be statistically significant (p ≤ 0.00001). Conclusions Atrophic pancreas in the preoperative CT scan may be protective against leakage after PD. These findings may help the surgeon to risk stratify patients accordingly. In addition, the findings suggest that patients with a preserved pancreas may require more protective methods to prevent leakage.

Abstract
Introduction Pancreaticoduodenectomy (PD) with superior mesenteric vein (SMV) reconstruction are often required to achieve complete (R0) resection for pancreatic head cancer (PHC) with tumor invasion of the SMV. Augmented reality (AR) technology can be used to assist in determining the extent of SMV involvement by superimposing virtual 3-dimensional (3D) images of the pancreas and regional vasculature on the surgical field. Materials and Methods Three patients with PHC and tumor invasion of the SMV underwent AR-assisted PD with SMV resection and reconstruction following preoperative computed tomography scanning. Preoperative imaging data were used to reconstruct 3D images of anatomical structures, including the tumor, portal vein (PV), SMV, and splenic vein (SV). Using AR software installed on a smart phone, the reconstructed 3D images were superimposed on the surgical field as viewed in a smart phone display to provide intermittent navigational assistance to the surgeon in identifying the boundaries of PHC tumor invasion for resection of the vessels involved. Result All patients successfully completed the operation. Intraoperative AR applications displayed virtual images of the pancreas, SMV, bile duct, common hepatic artery (CHA), and superior mesenteric artery (SMA). Two patients required end-to-end anastomosis for reconstruction of the SMV. One patient required allogenic vascular bypass to reconstruct the SMV-PV juncture with concomitant reconstruction of the SV-SMV confluence by end-to-side anastomosis of the SV and bypass vessel. Postoperative pathology confirmed R0 resections for all patients. Conclusion AR navigation technology based on preoperative CT image data can assist surgeons performing PD with SMV resection and reconstruction.

Abstract
An anomalous anatomy of the celiac trunk, and particularly of the right hepatic artery, may have a significant impact on major hepatobiliary and pancreatic surgery. According to some authors, every third patient has an aberrant right hepatic artery. We present a very rare case of replaced right hepatic artery (RRHA) arising from the gastroduodenal artery associated with an accessory left hepatic artery originating from the left gastric artery in a 54-year-old woman with a pancreatic head carcinoma. The patient underwent total pancreatectomy on account of a soft lipomatous pancreas with heterogeneous changes of the pancreatic body and tail. We preserved the RRHA and achieved R0 resection margins. Preoperative evaluation of CT angiograms, an awareness of any anomalous arterial anatomy of the upper abdomen, and a meticulous surgical technique are the key to performing oncologically radical surgery without threatening the arterial liver supply.

Abstract
Surgical options and approaches to pancreatic cancer are changing in the current era. Neoadjuvant treatment strategies for pancreatic cancer combined with the increased use of minimal access surgical techniques mean that the modern pancreatic surgeon requires mastering a number of surgical approaches with to optimally manage patients. Whilst traditional open surgery remains the most frequent approach for surgery, the specific steps during surgery may need to be modified in light of the aforementioned neoadjuvant treatments. Robotic and laparoscopic approaches to pancreatic resection are feasible, but these surgical methods remain in their infancy. In this review article, we summarise the current surgical approaches to pancreatic cancer and how these are adapted to the minimal access setting with discussion of the patient outcome data.

Abstract
BACKGROUND Precise classification of the hepatic artery is helpful for preoperative surgical planning in hepatobiliary-pancreatic surgery. However, the anatomy of hepatic arteries is variable. This study investigated anatomical variation using three-dimensional visualization and evaluation (3DVE) to develop a nomenclature system. METHODS The origin and course of the hepatic artery were tracked and analysed by using three-dimensional visualization of CT images acquired between 2013 and 2017. The new classification and nomenclature system, named CRL, was developed based on the origins of the common, right and left hepatic arteries. RESULTS Scans from 770 adults were evaluated. Preoperative 3DVE correlated better with surgical findings than the original CT images alone. Using the CRL classification system, hepatic arteries were divided into nine subtypes. Only 87·4-89·2 per cent of the hepatic arteries of 610 living-donor liver transplant donors were depicted in Michels', Hiatt's or Varotti's classification, compared with 100 per cent identified by the CRL classification. The CRL classification was validated against external data sets from previous studies, with 99·6-100·0 per cent of patients classified by the CRL system. CONCLUSION The CRL classification covers hepatic artery variants and may be used for planning liver surgery.

Abstract
Background:
Pancreaticoduodenectomy is the usual surgical option for curative treatment
of periampullary cancer and carries a significant mortality. Arterial
anomalies of the celiac axis are not uncommon and might lead to iatrogenic
lesions or requiring arterial resection/reconstruction in a
pancreatoduodenectomy.
Aim:
Determine the prevalence of arterial variations having implications in
pancreatoduodenectomy.
Methods:
Celiac trunk and hepatic arterial system anatomy was retrospectively
evaluated in 200 abdominal enhanced computed tomography studies.
Results:
Normal anatomy of hepatic arterial system was found in 87% of cases. An
anomalous right hepatic artery was identified in 13% of cases. In 12 cases
there was a substitute right hepatic artery arising from superior mesenteric
artery and in two cases an accessory right hepatic artery with similar
origin. A hepatomesenteric trunk was identified in seven cases and in five
there was a right hepatic artery directly from the celiac trunk. All cases
of anomalous right hepatic artery had a route was behind the pancreatic head
and then, posteriorly and laterally, to the main portal vein before reaching
the liver.
Conclusions:
Hepatic artery variations, such as anomalous right hepatic artery crossing
posterior to the portal vein, are frequently seen (13%). These patients,
when undergoing pancreatoduodenectomy, may require a change in the surgical
approach to achieve an adequate resection. Preoperative imaging can clearly
identify such variations and help to achieve a safer pancreatic head
dissection with proper surgical planning.

Abstract
"Artery-first approach" encompasses different aspects for the surgical treatment of pancreatic cancer. It is a surgical technique or set of techniques which share in common the dissection of the main arterial vasculature involved in pancreatic cancer, before any irreversible surgical step is performed. On the other hand it represents the need for a meticulous dissection of the arterial planes and clearing of the retropancreatic tissue between the superior mesenteric artery, the common hepatic artery and portal vein in an attempt to achieve R0 resections. The recent expansion of this approach is based mainly on three factors: venous involvement should not be considered a contraindication for resection, most of the pancreatic resections performed with a standard procedure may be in fact non-oncological (R1) resections and the postero-medial or vascular margin is the most frequently invaded by the tumor. This review aimed to summarize and update the artery-first approach in pancreaticoduodenectomy.

Abstract
Abstract Pancreatico-duodenectomy (PD) represents the standard surgical treatment for resectable malignancies of the pancreatic head, distal common bile duct, periampullary region and duodenum, and is also performed to manage selected benign tumours and refractory chronic pancreatitis. Despite improved surgical techniques and acceptable mortality, PD remains a technically demanding, high-risk operation burdened with high morbidity (complication rates 40–50% of patients). Multidetector computed tomography (CT) represents the mainstay modality to rapidly investigate the postoperative abdomen, and to provide a consistent basis for an appropriate choice between conservative, interventional or surgical treatment. However, radiologists require familiarity with the surgically altered anatomy, awareness of expected imaging appearances and possible complications to correctly interpret early post-PD CT studies. This paper provides an overview of surgical indications and techniques, discusses risk factors and clinical manifestations of the usual postsurgical complications, and suggests appropriate techniques and indications for early postoperative CT imaging. Afterwards, the usual, normal early post-PD CT findings are presented, including transient fluid, pneumobilia, delayed gastric emptying, identification of pancreatic gland remnant and of surgical anastomoses. Finally, several imaging examples review the most common and some unusual complications such as pancreatic fistula, bile leaks, abscesses, intraluminal and extraluminal haemorrhage, and acute pancreatitis. Teaching Points • Pancreatico-duodenectomy (PD) is a technically demanding surgery burdened with high morbidity (40–50%). • Multidetector CT is the mainstay technique to investigate suspected complications following PD. • Interpreting post-PD CT requires knowledge of surgically altered anatomy and expected findings. • CT showing collection at surgical site supports clinico-biological diagnosis of pancreatic fistula. • Other complications include biliary leaks, haemorrhage, abscesses and venous thrombosis.

Abstract
Surgery for the treatment of pancreatic cancer remains the gold standard, however, the identification of the vascular supply of the pancreas and the nearby organs remains a crucial difficulties in a curative resection. During pancreatic head resection for carcinoma dissection of regional arterial vasculature is mandatory. Normal coeliac and hepatic arterial anatomy occurs in ~50–70% of patients and multiple variations have been described. Knowledge of multiple arterial anomalies is essential in hepato-pancreatico-billary surgery to avoid unnecessary complications. The present study presents coeliac trunk and common hepatic artery (CHA) anomalies along with their clinical importance, as reviewed according to the available literature. Patients diagnosed with cancer of the pancreatic head were hospitalized for staging and planning of radical surgical therapy. Computed tomography (CT) revealed a large tumour mass in the head of the pancreas and CHA, which branched directly from the superior mesenteric artery. A three-dimensional CT reconstruction revealed a demonstrative vascular anomaly, which was confirmed during an operation. Despite the anomalous origin of the CHA, pylorus preserving pancreatoduodenectomy and regional lymph node dissection without intraoperative complications was performed in each case. The patient's postoperative clinical course was uneventful and adjuvant chemotherapy could be administered without delay. In the multidisciplinary treatment of pancreatic carcinoma the surgeon and radiologist must be aware of the aberrant anatomy in order to avoid potential complications. As CT scans used for the preoperative staging are of diagnostic value for vascular anomaly, it is required for appropriate surgical decision making.

Superior mesenteric artery first approach versus standard pancreaticoduodenectomy: a systematic review and meta-analysis. Hepatobiliary Pancreat Dis Int 2017; 16:127-138.

Abstract
BACKGROUND The superior mesenteric artery (SMA) first approach was proposed recently as a new modification of the standard pancreaticoduodenectomy. Increasing evidence showed that a periadventiceal dissection of the SMA with early transection of the inflow during pancreaticoduodenectomy associates better early perioperative results, and setup the scene for long-term oncological benefits. The objectives of the current study are to compare the operative results and long-term oncological outcomes of SMA first approach pancreaticoduodenectomy (SMA-PD) with standard pancreaticoduodenectomy (S-PD). DATA SOURCES Electronic search of the PubMed/MEDLINE, EMBASE, Web of Science and Cochrane Library was performed until July 2015. We considered randomized controlled trials (RCTs) and non-randomized comparative studies (NRCSs) comparing SMA-PD with S-PD to be eligible if they included patients with periampullary cancers. RESULTS A total of one RCT and thirteen NRCSs met the inclusion criteria, involving 640 patients with SMA-PD and 514 patients with S-PD. The SMA-PD was associated with less intraoperative bleeding, less blood transfusions and higher rate of associated venous resections. The pancreatic fistula and delayed gastric emptying had a significantly lower rate in the SMA-PD group. There were no differences between the two approaches regarding overall complications, major complication rates and in-hospital mortality. There was no difference regarding R0 resection rate, and one-, two- or three-year overall survival. The SMA-PD was associated with a lower local, hepatic and extrahepatic metastatic rate. CONCLUSIONS The SMA-PD is associated with better perioperative outcomes, such as blood loss, transfusion requirements, pancreatic fistula, and delayed gastric emptying. Although the one-, two- or three-year overall survival rate is not superior, the SMA-PD has a lower local and metastatic recurrence rate.

Abstract
BACKGROUND A majority of factors associated with the occurrence of clinical relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD) can only be identified intra- or postoperatively. There are no reports for assessing the morphological features of pancreatic stump and analyzing its influence on CR-POPF risk after PD preoperatively. METHOD A total of 90 patients underwent PD between April 2012 and May 2014 in our hospital were included. Preoperative computed tomographic (CT) images were imported into the Medical Image Three-Dimensional Visualization System (MI-3DVS) for acquiring the morphological features of pancreatic stump. The demographics, laboratory test and morphological features of pancreatic stump were recorded prospectively. The clinical course was evaluated focusing on the occurrence of pancreatic fistula as defined by the International Study Group on Pancreatic Fistula (ISGPF). Logistic regression analysis was used to identify independent predictors of CR-POPF. RESULTS CR-POPF occurred in 18 patients (14 grade B, 4 grade C). In univariate analysis, male gender (P = 0.026), body mass index (BMI) ≥ 25.3 kg/m(2) (P = 0.002), main pancreas duct diameter (MPDD) < 3.1 mm (P = 0.005), remnant pancreatic parenchymal volume (RPPV) > 27.8 mL (P < 0.001), and area of cut surface (AOCS) > 222.3 mm(2) (P < 0.001) were associated with an increased risk of CR-POPF. In multivariate analysis, BMI ≥ 25.3 kg/m(2) (OR 12.238, 95 % CI 1.822-82.215, P = 0.010) and RPPV > 27.8 mL (OR 12.907, 95 % CI 1.602-104.004, P = 0.016) were the only independent risk factors associated with CR-POPF. A cut-off value of 27.8 mL for RPPV established based on the receiver operating characteristic (ROC) curve, which was the strongest single predictive factor for CR-POPF, with a sensitivity and specificity of 77.8 and 86.1 %, respectively. The area under the ROC curve of RPPV was 0.770 (95 % CI 0.629-0.911, P < 0.001). CONCLUSIONS Our study demonstrated that CR-POPF is correlated with BMI and RRPV. MI-3DVS provides us a novel and convenient method for measuring the RPPV. Preoperative acquisition of RPPV and BMI may help the surgeons in fitting postoperative management to patient's individual risk after PD.

Abstract
Successful surgical resection offers the only chance for cure in patients with pancreatic cancer. However, pancreatic resection is feasible in less than 20% of the patients. In this review, the current state of surgical management of pancreatic cancer is discussed. The definition of resectability based on cross-sectional imaging and the technical aspects of surgery, including vascular resection and/or reconstruction, management of aberrant vascular anatomy and extent of lymphadenectomy, are appraised. Furthermore, common pancreatic resection-specific postoperative complications and their management are reviewed.
