A Case Report of Duodenal Malignancy and Its Management With Pancreaticoduodenectomy.

Gastrointestinal malignancies, most specifically duodenal malignancy, are uncommon in the population; however, they are tricky to manage because the lesions are diagnosed at a late stage and located in a complex area. This case report focuses on a patient who was diagnosed with a second (descending) part of the duodenum (D2) malignancy; the tumour was localised at the second part of the duodenum, and the management of this patient was through the Whipple procedure or pancreaticoduodenectomy. The patient complained of stinging abdomen pain. Diagnostic examination comprised of CT and biopsy proved the presence of a malignant tumour originating from the D2 area. The tumour's characteristics and the patient's general health status are determined by using Whipple's procedure. Post-operative management entails the use of IV antibiotics, analgesics, multivitamins and nasojejunal (NJ) tube feeding. The case also expounds on the consequences of a multimodal treatment strategy, meticulous planning of the surgical procedure, and adequate post-operative management of D2 malignancies. These data may shed some light on the peculiarities of duodenal cancer management with the Whipple procedure; nonetheless, early diagnosis and proper management should remain the primary goals.

Endoscopic clipping of gastrojejunostomy leakage following Whipple procedure: A case report.

BACKGROUND: Currently, perioperative complications of classic Whipple surgery occur at a rate of approximately 40%. Common complications include delayed gastric emptying, pancreatic fistula, and bile leakage, whereas gastrojejunostomy (GJ) leakage is rare. CASE SUMMARY: This case report will assess the management of a GJ leak in a 71-year-old male patient following the Whipple procedure. After surgery, the patient was transferred to the clinic after four days of intensive care, where vacuum therapy was used to handle a developing subcutaneous collection. The patient, who had bile in the drains and incision during follow-up, underwent endoscopic examination on the 21st day after the operation. An opening of approximately 4 mm was observed in the GJ anastomosis during endoscopy. Five titanium clips were used to close the openings. The drainage of bile decreased to less than 50 mL on the first day after the procedure, and the patient's oral intake was opened. CONCLUSION: Current literature reports a GJ leakage rate of 0. 54% following Whipple surgery, with clinical findings lasting on average between 4-34 days. Surgery was the main form of therapy for this case, with a success rate of 84%, and percutaneous drainage was also utilized as a treatment option. This case report is the first to document endoscopic treatment of GJ leaks following the classic Whipple procedure.

Impact of marmara-yegen cutting gastrojejunostomy on delayed gastric emptying after pancreatoduodenectomy: initial results.

BACKGROUND: Delayed gastric emptying (DGE) is one of the most common reasons for morbidity after pancreatoduodenectomy. The technical characteristics of anastomosis that could be affected by surgeon may offer a relevant chance to improve postoperative DGE rates. We investigated the effect of a technical modification of gastrojejunostomy after the classical pancreaticoduodenectomy on DGE. MATERIALS AND METHODS: A total of 161 patients underwent classical pancreaticoduodenectomy (with 20-40 percent antrectomy) due to pancreatic adenocarcinoma at the Department of General Surgery, Marmara University, School of Medicine Hospital, from February 2019 to May 2023, and those who met the inclusion criteria were enrolled. One hundred twenty patients had undergone classical end-to-side gastrojejunostomy (Classical GJ group), and 41 had undergone Marmara-Yegen cutting side-to-side gastrojejunostomy (M-Yc group). DGE was defined according to the International Working Group on Pancreatic Surgery, and postoperative DGE rates of both groups were compared. In addition, multivariate analysis was performed to identify possible independent predictive factors for DGE. RESULTS: The total incidence of DGE was 31% in the Classical GJ group and 17% in the (M-Yc group). Although there was no significant difference between the groups regarding DGE and DGE grades (p = 0.1), DGE was distinctly lower in the M-Yc GJ group. In multi-variant analysis, Clavien-Dindo grade 3a and above postoperative complication was determined as independent predictors for DGE. CONCLUSIONS: We tried to explain the mechanism of DGE in terms of anatomical configuration. The incidence and severity of DGE decreased in patients who underwent M-Yc GJ.

Duodenal obstruction in a 38-year-old: Case report of an unusual ovarian cancer presentation requiring a Whipple procedure.

Since ovarian cancer typically spreads intraperitoneally or via lymphatics, a retroperitoneal duodenal obstruction is a rare presentation of ovarian cancer. Such upper gastrointestinal obstruction in a young patient is diagnostically challenging and surgically difficult to address. In this case report, we describe that in an interdisciplinary approach a Whipple pancreaticoduodenectomy could be safely implemented into the interval debulking surgery to achieve complete cytoreduction. No postoperative complications were encountered. The surgical procedure was able to remove the upper gastrointestinal obstruction and thereby the need for a venting gastrostomy tube and total parenteral nutrition and thus provided good quality of life and additional lifetime.

A Complex Case of Obstructive Jaundice in a Septuagenarian: Diagnostic Challenges and Therapeutic Strategies.

Obstructive jaundice occurs when an obstruction in the bile duct system prevents bile from flowing from the liver into the intestine, accumulating bilirubin in the blood. This condition can result from various causes, including gallstones, tumors, or inflammation of the bile ducts. The management of obstructive jaundice depends on the underlying cause (malignant obstructions such as cholangiocarcinoma or pancreatic cancer), indicating the need for surgical intervention. The Whipple procedure (pancreaticoduodenectomy) is the standard curative approach for resectable distal common bile duct (CBD) adenocarcinoma. Doctors usually recommend adjuvant chemotherapy to reduce the risk of recurrence. We report the case of a 70-year-old male with a history of untreated hypertension, type 2 diabetes, and long-term smoking, who presented with classic signs of obstructive jaundice, including yellowing of the eyes, itching, right upper quadrant pain, and intermittent fevers. Laboratory findings revealed elevated inflammatory markers, bilirubin, liver enzymes, and leukocyte count, indicative of an inflammatory and obstructive biliary condition. Imaging studies confirmed a distal CBD stricture, including abdominal ultrasound, computed tomography scans, and endoscopic retrograde cholangiopancreatography (ERCP). Brush cytology obtained during ERCP revealed a well-differentiated adenocarcinoma of the distal CBD. The patient's treatment plan included preoperative optimization, surgical resection via the Whipple procedure, and postoperative adjuvant therapy. This case emphasizes the importance of a thorough diagnostic workup and a multidisciplinary treatment strategy in managing complex cases of obstructive jaundice in the elderly, highlighting the need for personalized care to achieve optimal outcomes.

Perioperative Spinal Cord Injury in the Setting of Whipple Procedure for Pancreatic Adenocarcinoma in a Patient With a History of Severe Cervical Stenosis.

Perioperative spinal cord injury (POSCI) is a form of traumatic acute spinal cord injury (TSCI) in the perioperative setting that is a rare but feared complication associated with severe morbidity and mortality, often resulting in significant functional impairment and significant healthcare costs for the patient. Here, we present a case report of a 65-year-old male with a past medical history of hypertension (HTN), type-2 diabetes mellitus (T2DM), stage 4 chronic kidney disease (CKD4) with a one-year history of anorexia, weight loss, jaundice, and right lower quadrant (RLQ) pain. He underwent an endoscopic ultrasound, which showed pancreatic atrophy, marked dilation of the main pancreatic duct, and a poorly defined pancreatic head mass. The patient underwent a successful pancreaticoduodenectomy and was extubated in the operating room and transferred to the surgical intensive care unit (SICU) on an oxygen face mask without complication. Four hours later it was noted that the patient's neurological exam had acutely changed with loss of motor and sensory function from the C7 dermatome down. The patient remained stable from a cardiopulmonary standpoint, and he was urgently transferred for emergency imaging of his brain and spinal cord, which demonstrated evidence of chronic spinal canal stenosis, complete cord flattening at the C5 level with profound cord edema centered at the C5 level extending from C3 to T1. Following diagnosis, neurosurgery was consulted at the SICU and a comprehensive neurological exam was performed. It was determined the patient had a grade A injury via the American Spinal Injury Association (ASIA) Impairment Scale and required an emergency cervical laminectomy. The patient was taken back to the operating room (OR) and an open cervical laminectomy was performed from C3 to C7 without any intraoperative complications. The patient was managed by a multidisciplinary SICU team for both his pancreaticoduodenectomy, perioperative traumatic acute spinal cord injury, and subsequent multilevel cervical laminectomies. The patient had a purposeful neurological recovery over the following weeks and was ultimately discharged to an inpatient physical rehabilitation facility.

Prevalence of autoimmune pancreatitis in pancreatic resection for suspected malignancy: a systematic review and meta-analysis.

BACKGROUND/OBJECTIVES: Autoimmune pancreatitis (AIP) is a diagnosis-challenging disease that often mimics pancreatic malignancy. Pancreatic resection is considered to be a curative treatment for pancreatic ductal adenocarcinoma (PDAC). This meta-analysis aims to study the incidence of AIP in patients who have undergone pancreatic resection for clinical manifestation of cancer. METHODS: A comprehensive search was conducted in three databases, PubMed, Embase and the Cochrane Library, using the terms 'autoimmune pancreatitis' and 'pancreatic resection' and supplemented by manual checks of reference lists in all retrieved articles. RESULTS: Ten articles were included in the final analysis. 8917 pancreatic resections were performed because of a clinical suspicion of pancreatic cancer. AIP accounted for 140 cases (1.6%). Type 1 AIP comprised the majority of cases, representing 94% (132 cases), while type 2 AIP made up the remaining 6% (eight cases) after further classification. AIP accounted for almost 26% of all cases of benign diseases involving unnecessary surgery and was overrepresented in males in 70% of cases compared to 30% in females. The mean age for AIP patients was 59 years. Serum CA 19 - 9 levels were elevated in 23 out of 47 (49%) AIP patients, where higher levels were detected more frequently in patients with type 1 AIP (51%, 22 out of 43) than in those with type 2 AIP (25%, 1 out of 4). The sensitivity of IgG4 levels in type 1 AIP was low (43%, 21/49 patients). CONCLUSION: Even with modern diagnostic methods, distinguishing between AIP and PDAC can still be challenging, thus potentially resulting in unnecessary surgical procedures in some cases. Serum CA 19 - 9 levels are not useful in distinguishing between AIP and PDAC. Work must thus be done to improve diagnostic methods and avoid unnecessary complicated surgery.

Open vs robotic-assisted pancreaticoduodenectomy, cost-effectiveness and long-term oncologic outcomes: a systematic review and meta-analysis.

BACKGROUND: Whipple pancreaticoduodenectomy (PD) is a complex gastrointestinal surgery that is performed increasingly via minimally invasive approach through robotic platforms. We sought to provide a comparative review of available data regarding robot-assisted vs open PD in terms of cost-effectiveness, overall survival, and other perioperative and long-term oncologic outcomes. METHODS: Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria, PubMed, Scopus, and Web of Science databases were searched from 1980 to April 2024 using designated keywords. English-language studies comparing costs and oncologic outcomes of robotic vs open PDs were considered for inclusion. Reviews, abstracts, case reports, letters to the editor, and non-English articles were excluded. RESULTS: A total of 1733 studies were initially identified throughout the literature search. After the removal of duplicates, title and abstract screening identified 16 studies that were included in the review. No statistically significant differences were detected in terms of short-term complications (95% CI, 0.805-1.096; P = .42), mortality (95% CI, 0.599-1.123; P = .21), and readmission (95% CI, 0.959-1.211; P = .20) among patients undergoing open vs robotic PD. Robotic PDs was associated with a slightly better overall survival (95% CI, 1.020-1.233) and higher costs (95% CI, 0.134-1.139; P = .013). Mean length of stay (LOS) was higher in the open PD group (95% CI, -0.353 to 0.189; P < .001). CONCLUSION: Robotic-assisted PD had a slightly shorter LOS and improved overall survival. There were no differences in short-term complications, mortality, or readmission. The use of cohort studies and residual potential selection bias necessitate randomized controlled trials to define the benefit of robotic PD.

Initial Experience of Pancreaticoduodenectomy in a Newly Developed Hepato-Pancreato-Biliary Unit Serving in a Lower-Middle-Income Country.

Introduction: Pancreaticoduodenectomy (PD) is the only potentially curative treatment for pancreatic head adenocarcinoma. This study aimed to determine the short-term outcomes of PD performed over 1 year at a newly established hepato-pancreatico-biliary unit in Khyber Pakhtunkhwa province of Pakistan. Material and Methods: A retrospective analysis of a prospectively maintained hospital information system (HIS) was undertaken of all patients referred to the unit between May 2021 and August 2022. Data were collected from the medical records of patients in the HIS. Data were analyzed for primary location, age, complications, and operative parameters. Results: The primary sites of disease were ampulla (n = 18, 52.9%), pancreas (n = 11, 32.4%), and duodenum (n = 5, 14.7%). The median duration of surgery was 7 h. 16 (47.1%) patients required blood transfusion either intraoperatively or in the perioperative period. Patients with pre-operative biliary drainage (PBD) were more likely to have multidrug-resistant positive bile cultures with a P-value of 0.2 (n = 12 [35.3%] vs. n = 5 [14.7%]). Overall morbidity was 38.2%. The most common complications were wound infection (n = 12, 35.3%), delayed gastric emptying (n = 6, 17.6%), and type B pancreatic fistula (n = 3, 8.8%). The complication rate was higher in patients with biliary stenting (n = 11 [32.4%] vs. n = 2 [5.9%]; P = 0.06). The median length of hospital stay for patients without complications was less (6 vs. 12 days; P < 0.001). The complication rate was lower in total laparoscopic PD (TLPD) with P = 0.4 (TLPD: 2.9%, open: 23.5%, laparoscopic assisted: 11.8%). 90-day mortality was zero. Conclusion: Short-term outcomes for PD in our facility are comparable to high-volume centers. PBD can significantly increase operative time, hospital stay, and morbidity.

Pancreaticoduodenectomy in Patients With Coeliac or Superior Mesenteric Artery Stenosis: A Review of the Literature.

Pancreaticoduodenectomy (Whipple's procedure) is a technically demanding operation performed for malignant and premalignant conditions of the pancreatic head, duodenum and bile duct. Awareness of the vascular anatomy, variations, and pathology of this area is essential to achieve safe surgery and good outcomes. The operation involves division of the gastroduodenal artery (GDA) which provides communication between the foregut and midgut blood supply. In patients with coeliac or superior mesenteric artery (SMA) stenosis, this can lead to reduced blood supply to the foregut or midgut organs, with consequent severe ischaemic complications leading to significant morbidity and mortality. Coeliac artery stenosis is caused by median arcuate ligament syndrome (MALS) in the majority of patients with atherosclerosis being the second most common cause. SMA stenosis is much less common and is caused in the majority of cases by atherosclerosis. A review of preoperative imaging and intraoperative gastroduodenal artery clamp test is important to identify cases that may need additional procedures to preserve the blood supply. In this paper, we present a literature review for studies reporting patients undergoing Whipple's operation with concomitant coeliac axis stenosis (CAS) or SMA stenosis. Analysis of causes of stenosis or occlusion, prevalence, risk factors, different management strategies and outcomes was conducted.

Laparoscopic Total Pancreatectomy After Laparoscopic Whipple.

BACKGROUND: The incidence of a second de novo pancreatic ductal adenocarcinoma (PDAC) among patients with prior cancer has been reported to be 6%.1,2 however, as survival increases through improvements in systemic therapy, this incidence of a de novo PDAC after prior PDAC may become more prevalent.3-8 In this context, a structured and stepwise approach to a total pancreatectomy for a second de novo PDAC after a prior PDAC treated with a pancreaticoduodenectomy is detailed. PATIENTS: We present two similar cases. The first patient was a 71-year-old female with de novo body PDAC, and the second was a 50-year-old female with de novo tail PDAC. To rule out recurrence, immunohistochemical staining as well as the review of biopsies by two experienced pathologists were employed. Both patients had undergone a laparoscopic pancreatoduodenectomy for PDAC 4 and 3 years prior. Each patient received four cycles of neoadjuvant chemotherapy and underwent a safe laparoscopic total pancreatectomy. TECHNIQUE: Prior to surgery, three-dimensional anatomic and port site modeling is performed to optimize the understanding of the spatial relationship between the tumor, blood vessels, and adjacent organs involved. The port site modeling (including pneumoperitoneum simulation) focuses on the optimal port set-up for dissecting the biliopancreatic limb off the portal vein. Following complete mobilization of the biliopancreatic limb, the biliopancreatic limb is staple-divided between the hepatico- and pancreaticojejunostomy. Great care must be taken to avoid accidental staple injury to the hepatic artery or celiac trunk. The remainder of the dissection is akin to a standard distal pancreaticosplenectomy. CONCLUSION: Virtual pancreatectomy modeling facilitates an optimal set-up for the critical step of this case, i.e. dissection of the pancreaticojejunostomy off the portal vein. Early division of the biliopancreatic limb between hepatico- and pancreatojejunostomy is crucial to facilitating the remainder of the dissection. Laparoscopic total pancreatectomy for a de novo PDAC after laparoscopic pancreaticoduodenectomy may become more common as survival of patients with prior PDAC improves over time.

Benign Etiology for High-Risk Intraductal Papillary Mucinous Neoplasm: A Case Report and Literature Review.

Intraductal papillary mucinous neoplasms are relatively common and entail a variable risk of malignant potential. The Fukuoka guidelines present criteria for the risk of malignant transformation and are used for risk stratification and treatment decision-making. However, these guidelines entail some fallibility with limited sensitivity and specificity. In this case, we present an individual who had many of the hallmarks of malignant transformation but was found to have no evidence of malignancy or high-grade dysplasia. We discuss the suspected etiology of this individual's condition and how it might arise in others, as well as a brief review of the literature on risk factors in intraductal papillary mucinous neoplasms.

Incidental Discovery of a Phrygian Cap During Whipple's Procedure: A Case Report.

Obstructive jaundice, characterised by yellow discolouration of the skin and mucous membranes due to reduced bile flow, often necessitates surgical intervention for resolution. This article provides a comprehensive literature review to contextualise the management of obstructive jaundice, focusing on common treatment modalities such as common bile duct (CBD) stenting and Whipple's procedure for pancreatic head cancer. Additionally, the incidental finding of a Phrygian cap of the gallbladder during surgical intervention for pancreatic head cancer is described in detail. A case presentation of a 48-year-old female with obstructive jaundice and pancreatic head cancer is outlined, detailing the diagnostic process, treatment decisions, and surgical interventions. The patient underwent CBD stenting followed by Whipple's procedure to address the pancreatic head cancer, during which the incidental discovery of a Phrygian cap of the gallbladder was noted. The discussion of the incidental finding highlights the complexity it adds to surgical interventions and emphasises the importance of adaptability and precision in managing anatomical variations. A comparison with similar cases underscores varying approaches to managing incidental findings, ranging from conservative observation to surgical excision based on clinical indications. This case underscores the significance of thorough diagnostic evaluation and surgical intervention in managing incidental findings such as the Phrygian cap, ensuring appropriate patient management and favourable clinical outcomes in complex surgical scenarios.

Transenteric Endoscopic Retrograde Cholangiopancreatography in Non-roux-en-Y Surgically Altered Anatomy.

EDEE is a relatively safe and effective procedure when performed by expert endoscopists to establish pancreaticobiliary access in patients who have failed, or are not candidates for, traditional ERCP or alternative drainage modalities. Careful preprocedural planning with attention to the patient's specific postsurgical anatomy can optimize outcomes and minimize AEs.

Case report: a case report of neoadjuvant mFOLFIRINOX leading to a partial pathologic response in pancreatic adenosquamous carcinoma.

A female in her 60s with vague abdominal symptoms was found to have a pancreatic mass in her CT scan. A core needle biopsy done endoscopically demonstrated a poorly differentiated adenocarcinoma. The patient completed nine cycles of neoadjuvant systemic mFOLFIRINOX. Repeat staging demonstrated a partial radiographic response. She underwent an open pylorus-preserving pancreatoduodenectomy with segmental superior mesenteric vein resection with primary reconstruction (ISGPS Type 3). The final pathology demonstrated a poorly differentiated adenosquamous carcinoma, R1 margin status. The case report demonstrates the effect of mFOLFIRINOX on pancreatic adenosquamous (PASC) carcinoma with a review of the microscopic pictures following the neoadjuvant therapy. It can be postulated that glandular component being the major component in a PASC has a good response to mFOLFIRINOX like that seen in pancreatic ductal adenocarcinoma with some presumed effect on the squamous component as well. From the above case report, we are proposing that mFOLFIRINOX can be an effective chemotherapy regime in the management of PASC.

Comparative Outcomes of Minimally Invasive Versus Open Pancreatoduodenectomy in Distal Cholangiocarcinoma: A Systematic Review and Meta-Analysis.

Pancreatoduodenectomy, the primary surgical strategy for managing cholangiocarcinoma, is executed via two distinct methodologies, namely minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD). The selection between these surgical options is critical, as it directly influences patient outcomes, encompassing both short-term recovery metrics and long-term survival rates. Despite the clinical significance of these procedures, there exists a notable void in the literature regarding a comprehensive comparison of MIPD and OPD, particularly in assessing their respective efficacies and complications. This lack of detailed comparative analysis has left a gap in evidence-based guidance for clinicians faced with the decision of choosing the most appropriate surgical approach for their patients. The absence of robust data comparing the two techniques underscores the necessity for a meta-analysis that rigorously examines and contrasts the outcomes associated with MIPD and OPD. By drawing upon a wide array of international studies, this research aims to shed light on the advantages and potential drawbacks of each method, thereby providing a more informed basis for surgical decision-making in the treatment of cholangiocarcinoma.

Benign Lesion of the Common Bile Duct Mimicking a Malignant Tumor: an Entity Commonly Overdiagnosed Clinically.

Adenomyomatous hyperplasia and adenomyoma are rare benign inflammatory pseudotumors of the gallbladder arising from Rokitansky-Aschoff sinuses. Occurrence of these hyperplastic conditions in the Vaterian and biliary system is extremely rare and is a concern for gastroenterologists and surgeons in distinguishing them from primary malignancies of the biliary system. Definitive diagnosis by imaging or cytopathological examination is difficult; thus, surgical resection becomes the only choice in such cases to relieve the obstruction. Here, we report two extremely rare cases of adenomyomatous hyperplasia of the extrahepatic bile duct after an extensive diagnostic workup, followed by Whipple's procedure.

Association between perineural infiltrations and delayed gastric emptying after Whipple procedure for periampullary tumours, and the relationship with other clinicopathological factors and overall survival.

Introduction: Pancreaticoduodenectomy is a major procedure. Delayed gastric emptying (DGE) is a frequent postoperative complication that is attributed to several factors. Aim: To investigate the probable association between perineural infiltrations and DGE, and the effects on overall survival. Material and methods: A total of 123 patients who underwent pancreaticoduodenectomy were enrolled in the study. Factors like the presence of perineural infiltrations and post-operative DGE along with age, gender, presence of postoperative fistula, and grade of fistula and postoperative haemorrhage were analysed, and survival analyses were conducted. Results: The presence of perineural infiltrations is statistically associated with DGE occurrence (p = 0.01). Moreover, the occurrence of DGE is statistically associated with male gender (p = 0.001), worse grade of postoperative fistula (p < 0.01), and the presence of postoperative haemorrhage (p = 0.03). There was no statistical association between the presence of perineural infiltrations and the other factors. Cox regression and Kaplan-Meier survival analyses showed that increased overall survival is associated with low age (p = 0.018 and p = 0.028, respectively), absence of perineural infiltrations (p = 0.005 and p = 0.003, respectively), better grade of postoperative fistula (p < 0.001), and absence of postoperative haemorrhage (p < 0.001). Multivariate analysis showed that independent prognostic factors for survival prognosis are perineural infiltrations, age, the presence of postoperative pancreatic fistula, and the presence of postoperative haemorrhage. Conclusions: This is the first study that proves a statistically significant association between the presence of perineural infiltrations and the occurrence of DGE. Moreover, perineural infiltrations are an important independent prognostic factor for overall survival, along with other clinical factors.

Value of the surgical pancreatic duct anatomy and associated outcomes in pancreatic cancer.

INTRODUCTION: Pancreatic cancer recurrence following surgery is a significant challenge, and personalized surgical care is crucial. Topographical variations in pancreatic duct anatomy are frequent but often underestimated. This study aimed to investigate the potential importance of these variations in outcomes and patient survival after Whipple's procedures. METHODS: Data were collected from 105 patients with confirmed pancreatic head neoplasms who underwent surgery between 2008 and 2020. Radiological measurements of pancreatic duct location were performed, and statistical analysis was carried out using IBM SPSS. RESULTS: Inferior pancreatic duct topography was associated with an increased rate of metastatic spread and tumour recurrence. Additionally, inferior duct topography was associated with reduced overall and recurrence-free survival. Posterior pancreatic duct topography was associated with decreased incidence of perineural sheet infiltration and improved overall survival. DISCUSSION: These findings suggest that topographical diversity of pancreatic duct location can impact outcomes in Whipple's procedures. Intraoperative review of pancreatic duct location could help surgeons define areas of risk or safety and deliver a personalized surgical approach for patients with beneficial or deleterious anatomical profiles. This study provides valuable information to improve surgical management by identifying high-risk patients and delivering a personalized surgical approach with prognosis stratification.

Utility of gastrostomy tube placement at the time of pancreaticoduodenectomy.

PURPOSE: The aim of this study is to investigate the utility of gastrostomy tube (G-tube) placement in reducing delayed gastric emptying (DGE) among patients undergoing pancreaticoduodenectomy (PD). METHODS: We retrospectively reviewed consecutive patients undergoing PD from 2015 to 2020 at our institution. Thirty-day patient outcomes including DGE, length of stay (LOS), reoperation rates, and morbidity were analyzed in patients with or without G-tube placement. RESULTS: 128 patients with resectable pancreatic head cancer (54 females, median age 68.50 [59.00-74.00]) underwent PD (66 had G-tube placement and 62 did not). There was no significant difference in the incidence of DGE (n = 17 vs. n = 17, p = 0.612), and LOS between the groups. Postoperative ileus (p = 0.007) was significantly lower while atrial fibrillation (p = 0.037) was higher among the G-tube group. Gastrostomy-related complications (p = 0.001) developed in ten patients: skin-related complications (n = 6), tube dislodgement (n = 3) and clogging (n = 1). Nine patients required reoperation during index admission (n = 4 vs. n = 5, p = 1.000). There was no difference in 30-day readmissions (n = 7 vs. n = 5, p = 0.471) and no difference in 30 or 90-day mortality. CONCLUSION: Gastrostomy tube placement during index PD did not affect the incidence of DGE. However, patients experienced significant morbidities due to G-tube-related complications. Placement of gastrostomy tubes at the index PD offers no clinical benefits.
