MRI-Pathology Agreement in Rectal Cancer: Real-World Data from a Prospective Rectal Cancer Registry.

Introduction: Magnetic Resonance Imaging (MRI) is routinely used in preoperative rectal cancer staging. The concordance of MRI staging with final pathologic exam, albeit improved, has not yet reached perfection. The aim of this study is to analyze the agreement between MRI and pathologic exam in patients operated on for mid-low rectal cancer. Material and Method: Patients undergoing neoadjuvant chemoradiation therapy (nCRT) or upfront surgery were analyzed. Between January 2019 to December 2019, 140 patients enrolled in the AIMS Academy rectal cancer registry were analyzed. Sixty-two patients received nCRT and 78 underwent upfront surgery. Results: Overall, the agreement between MRI and pathologic exam on T stage and N stage were 64.7% and 69.2%, respectively. The agreement between MRI and pathologic exam on T stage was 62.7% for patients who did not receive nCRT and 67.4% for patients who received nCRT (p = 0.62). The agreement on N stage was 76.3% for patients who did not receive nCRT and 60.0% for patients who received nCRT (p = 0.075). Conclusions: Real-world data shows MRI is still far from being able to correlate with the pathology findings which raises questions about the accuracy of the real-life decision-making process during cancer boards.

Low Ligation of Inferior Mesenteric Artery in Laparoscopic Anterior Resection for Rectal Cancer Reduces Genitourinary Dysfunction: Results From a Randomized Controlled Trial (HIGHLOW Trial).

OBJECTIVES: The aim of the present study was to compare the incidence of genitourinary (GU) dysfunction after elective laparoscopic low anterior rectal resection and total mesorectal excision (LAR + TME) with high or low ligation (LL) of the inferior mesenteric artery (IMA). Secondary aims included the incidence of anastomotic leakage and oncological outcomes. BACKGROUND: The criterion standard surgical approach for rectal cancer is LAR + TME. The level of artery ligation remains an issue related to functional outcome, anastomotic leak rate, and oncological adequacy. Retrospective studies failed to provide strong evidence in favor of one particular vascular approach and the specific impact on GU function is poorly understood. METHODS: Between June 2014 and December 2016, patients who underwent elective laparoscopic LAR + TME in 6 Italian nonacademic hospitals were randomized to high ligation (HL) or LL of IMA after meeting the inclusion criteria. GU function was evaluated using a standardized survey and uroflowmetric examination. The trial was registered under the ClinicalTrials.gov Identifier NCT02153801. RESULTS: A total of 214 patients were randomized to HL (n = 111) or LL (n = 103). GU function was impaired in both groups after surgery. LL group reported better continence and less obstructive urinary symptoms and improved quality of life at 9 months postoperative. Sexual function was better in the LL group compared to HL group at 9 months. Urinated volume, maximum urinary flow, and flow time were significantly (P < 0.05) in favor of the LL group at 1 and 9 months from surgery. The ultrasound measured post void residual volume and average urinary flow were significantly (P < 0.05) better in the LL group at 9 months postoperatively. Time of flow worsened in both groups at 9 months compared to baseline. There was no difference in anastomotic leak rate (8.1% HL vs 6.7% LL). There were no differences in terms of blood loss, surgical times, postoperative complications, and initial oncological outcomes between groups. CONCLUSIONS: LL of the IMA in LAR + TME results in better GU function preservation without affecting initial oncological outcomes. HL does not seem to increase the anastomotic leak rate.

Laparoscopic repair of voluminous symptomatic hiatal hernia using absorbable synthetic mesh.

INTRODUCTION: Hiatal hernia is a common disorder and a controversial topic. In symptomatic voluminous hernias laparoscopic surgery and use of mesh can be considered. An initial experience in voluminous hiatal hernia laparoscopic repair using absorbable glycolic acid/trimethylene carbonate synthetic mesh is reported. MATERIAL AND METHODS: Retrospective study from an institutional database was performed to analyze laparoscopic hiatal hernia repair using absorbable synthetic mesh from January 2010 to December 2013. All preoperative symptoms and exams were collected and a standardized procedure was performed. Clinical and radiological follow-up was performed. RESULTS: Eight patients underwent laparoscopic repair of hiatal hernia performed by two highly skilled laparoscopic surgeons. One Toupet and seven Nissen fundoplications were tailored. No conversions into laparotomy, neither intraoperative complications nor mortality occurred. After a median follow-up of 23.5 months (range 14 - 44) no mesh complications occurred and all patients are asymptomatic. Two radiological recurrences (25%) were detected. CONCLUSIONS: Voluminous symptomatic hiatal hernias can be successfully treated in a high-volume and long-term experienced laparoscopic surgical center by the use of an absorbable synthetic mesh. Further studies and a longer-term follow-up are necessary to confirm this preliminary report.

A pragmatic approach improves the clinical management of stage IV gastric cancer: Comparison between the Meta-Gastro results and the GIRCG's retrospective series.

INTRODUCTION: The Italian Research Group for Gastric Cancer developed a prospective database about stage IV gastric cancer, to evaluate how a pragmatic attitude impacts the management of these patients. MATERIALS AND METHODS: We prospectively collected data about metastatic gastric cancer patients thanks to cooperation between radiologists, oncologists and surgeons and we analyzed survival and prognostic factors, comparing the results to those obtained in our retrospective study. RESULTS: Three-hundred and eighty-three patients were enrolled from 2018 to September 2022. We observed a higher percentage of laparoscopic exploration with peritoneal lavage in the prospective cohort. In the registry only 3.6 % of patients was submitted to surgery without associated chemotherapy, while in the retrospective population 44.3 % of patients were operated on without any chemotherapy. At univariate and multivariate analyses, the different metastatic sites did not show any survival differences among each other (OS 20.0 vs 16.10 vs 16.7 months for lymphnodal, peritoneal and hepatic metastases, respectively), while the number of metastatic sites and the type of treatment showed a statistical significance (OS 16,7 vs 13,0 vs 4,5 months for 1, 2 and 3 different metastatic sites respectively, p < 0.001; 24,2 vs 12,0 vs 2,5 months for surgery with/without chemotherapy, chemotherapy alone and best supportive treatment respectively, p < 0.001). CONCLUSIONS: Our data highlight that the different metastatic sites did not show different survivals, but survival is worse in case of multiple localization. In patients where a curative resection can be achieved, acceptable survival rates are possible. A better diagnostic workup and a more accurate staging impact favorably upon survival.

Clinical outcomes of patients with complicated post-operative course after gastrectomy for cancer: a GIRCG study using the GASTRODATA registry.

Gastrectomy for gastric cancer is still performed in Western countries with high morbidity and mortality. Post-operative complications are frequent, and effective diagnosis and treatment of complications is crucial to lower the mortality rates. In 2015, a project was launched by the EGCA with the aim of building an agreement on list and definitions of post-operative complications specific for gastrectomy. In 2018, the platform www.gastrodata.org was launched for collecting cases by utilizing this new complication list. In the present paper, the Italian Research Group for Gastric Cancer endorsed a collection of complicated cases in the period 2015-2019, with the aim of investigating the clinical pictures, diagnostic modalities, and treatment approaches, as well as outcome measures of patients experiencing almost one post-operative complication. Fifteen centers across Italy provided 386 cases with a total of 538 complications (mean 1.4 complication/patient). The most frequent complications were non-surgical infections (gastrointestinal, pulmonary, and urinary) and anastomotic leaks, accounting for 29.2% and 17.3% of complicated patients, with a median Clavien-Dindo score of II and IIIB, respectively. Overall mortality of this series was 12.4%, while mortality of patients with anastomotic leak was 25.4%. The clinical presentation with systemic septic signs, the timing of diagnosis, and the hospital volume were the most relevant factors influencing outcome.

Oligometastatic Gastric Cancer: Clinical Data from the Meta-Gastro Prospective Register of the Italian Research Group on Gastric Cancer.

BACKGROUND: Interest in the field of metastatic gastric cancer has grown in recent years, and the identification of oligometastatic patients plays a critical role as it consents to their inclusion in multimodal treatment strategies, which include systemic therapy but also surgery with curative intent. To collect sound clinical data on this subject, The Italian Research Group on Gastric Cancer developed a prospective multicentric observational register of metastatic gastric cancer patients called META-GASTRO. METHODS: Data on 383 patients in Meta-Gastro were mined to help our understanding of oligometastatic, according to its double definition: quantitative/anatomical and dynamic. RESULTS: the quantitative/anatomical definition applies to single-site metastases independently from the metastatic site (p < 0.001) to peritoneal metastases with PCI ≤ 12 (p = 0.009), to 1 or 2 hepatic metastases (p = 0.024) and nodal metastases in station 16 (p = 0.002). The dynamic definition applies to a percentage of cases variable according to the metastatic site: 8%, 13.5 and 23.8% for hepatic, lymphatic and peritoneal sites, respectively. In all cases, the OS of patients benefitting from conversion therapy was similar to those of cases deemed operable at diagnosis and operated after neoadjuvant chemotherapy. CONCLUSIONS: META-GASTRO supports the two-fold definition of oligometastatic gastric cancer: the quantitative/anatomical one, which accounts for 30% of our population, and the dynamic one, observed in 16% of our cases.

Surgical technique, morbidity, and outcome of primary retroperitoneal sarcoma involving inferior vena cava.

BACKGROUND: Retroperitoneal sarcomas (RSTS) involving inferior vena cava (IVC) are rare entities. Vascular resection and reconstruction represent a technical challenge. The aim of the study was to review a monoinstitutional series of IVC resections for RSTS (mainly IVC leiomyosarcoma), focusing on the type of vascular replacement, morbidity, and oncologic outcome. METHODS: From January 2004 to January 2011, 15 patients (7 male, 8 female) surgically treated for RSTS involving primarily or secondarily IVC were included. RESULTS: A total of ten patients had IVC replacement and one had partial IVC resection (anterior wall). En bloc organ resection was performed in 14 patients (93%). Major venous reconstructions were performed using PTFE prosthesis (2) or banked venous homografts (8). In four patients IVC reconstruction was not necessary because of the presence of efficient collaterals. Early clinically relevant complications (grade ≥3) were detected in one patient (7%) (symptomatic graft thrombosis). No reoperations were needed. No late relevant complications (grade ≥3) were observed. Overall graft patency was 60%. At a median follow up of 31.6 months, local recurrence, distant metastases, and survival rate were 20, 26, and 80%, respectively. Complete tumor resection was achieved in all patients. CONCLUSIONS: IVC resection is safe and well tolerated in RSTS patients. The need for vascular reconstruction has to be assessed according to preoperative imaging, intraoperative findings, and extent of resection. The specific role of banked venous homografts needs to be investigated in larger studies.

Morbidity of left pancreatectomy when associated with multivisceral resection for abdominal mesenchymal neoplasms.

CONTEXT: Resection of adjacent visceral organs is often required in surgery for abdominal mesenchymal tumors. OBJECTIVES: To analyze the specific perioperative morbidity and mortality of a left pancreatectomy in multivisceral resections for mesenchymal tumors. PATIENTS: This paper considered all patients treated at National Cancer Institute, Milan, Italy, from January 1997 to May 2009 for the resection of abdominal mesenchymal neoplasms requiring a concomitant left pancreatectomy. The extension of surgery, pathology of both the tumor and the pancreatic tissue, completeness of resection, administration of pre or postoperative treatments and postoperative outcome were analyzed. The overall survival of the entire population was also assessed. RESULTS: Fifty-seven patients affected by localized left retroperitoneal mesenchymal neoplasms or intra-abdominal gastrointestinal stromal tumors were identified. A macroscopically complete resection was achieved in all but 3 patients (5.3%) and the neoplastic involvement of pancreatic tissue was documented at pathology in 26 (45.6%) patients. Surgical postoperative complications occurred in 20 patients (35.1%); 7 patients (12.3%) developed a postoperative pancreatic fistula. With a median follow-up of the surviving patients of 32 months (interquartile range: 20-57 months), the overall survival at 5 years was 67.0%. CONCLUSION: Left pancreatic resection seemed to be a safe procedure, even when it is part of a multivisceral resection for abdominal mesenchymal neoplasms. When margins are crucial for cure, the left pancreas should then always be resected, independently of its direct infiltration.

Evaluation of global and intragenic hypomethylation in colorectal adenomas improves patient stratification and colorectal cancer risk prediction.

BACKGROUND: Aberrant DNA hypomethylation of the long interspersed nuclear elements (LINE-1 or L1) has been recognized as an early event of colorectal transformation. Simultaneous genetic and epigenetic analysis of colorectal adenomas may be an effective and rapid strategy to identify key biological features leading to accelerated colorectal tumorigenesis. In particular, global and/or intragenic LINE-1 hypomethylation of adenomas may represent a helpful tool for improving colorectal cancer (CRC) risk stratification of patients after surgical removal of polyps. To verify this hypothesis, we analyzed a cohort of 102 adenomas derived from 40 high-risk patients (who developed CRC in a post-polypectomy of at least one year) and 43 low-risk patients (who did not develop CRC in a post-polypectomy of at least 5 years) for their main pathological features, the presence of hotspot variants in driver oncogenes (KRAS, NRAS, BRAF and PIK3CA), global (LINE-1) and intragenic (L1-MET) methylation status. RESULTS: In addition to a significantly higher adenoma size and an older patients' age, adenomas from high-risk patients were more hypomethylated than those from low-risk patients for both global and intragenic LINE-1 assays. DNA hypomethylation, measured by pyrosequencing, was independent from other parameters, including the presence of oncogenic hotspot variants detected by mass spectrometry. Combining LINE-1 and L1-MET analyses and profiling the samples according to the presence of at least one hypomethylated assay improved the discrimination between high and low risk lesions (p = 0.005). Remarkably, adenomas with at least one hypomethylated assay identified the patients with a significantly (p < 0.001) higher risk of developing CRC. Multivariable analysis and logistic regression evaluated by the ROC curves proved that methylation status was an independent variable improving cancer risk prediction (p = 0.02). CONCLUSIONS: LINE-1 and L1-MET hypomethylation in colorectal adenomas are associated with a higher risk of developing CRC. DNA global and intragenic hypomethylation are independent markers that could be used in combination to successfully improve the stratification of patients who enter a colonoscopy surveillance program.

Aggressive surgery in retroperitoneal soft tissue sarcoma carried out at high-volume centers is safe and is associated with improved local control.

BACKGROUND: We sought to assess morbidity and mortality in primary retroperitoneal soft tissue sarcomas (RSTS) treated by a frontline aggressive surgical approach. METHODS: A total of 249 consecutive patients with primary RSTS were treated by a frontline aggressive surgical approach at two major European institutions. Multivariable models were used for exploring the relationship between postsurgical morbidity and the number of organs resected, with adjustment for clinical variables. The impact of morbidity on local and distant recurrence-free survival was explored by multivariable models, adjusting for the main known prognostic factors. RESULTS: Median follow-up was 37 months (interquartile [IQ] range, 16-61 months). Median tumor size was 17 cm (IQ range, 11-26 cm). The median number of organs resected en bloc with the tumor was 2 (IQ range, 1-3). Complete macroscopic resection was achieved in 232 cases (93%). At 5 years, overall survival was 65.4% (95% confidence interval [95% CI], 56.8-72.7); local and distant recurrence crude cumulative incidences were 22.3% (95% CI, 16.5-30.2) and 24.2% (95% CI, 18.4-31.9), respectively. Postsurgical morbidity requiring at least one invasive therapeutic procedure was observed in 45 patients (18%; 95% CI, 14-23). Surgical reintervention was necessary in 30 patients (12%; 95% CI, 8-17). Eight patients died of postoperative complications (3%; 95% CI, 1-6). No statistically significant association between postsurgical morbidity and any clinical variable was detected. For number of resected organs, we documented an increased risk of morbidity for more than three organs (P = 0.007). Postsurgical morbidity did not affect oncologic outcome. CONCLUSIONS: Frontline aggressive surgical approach to primary RSTS is safe when carried out at high-volume centers. It could be systematically considered in primary RSTS.

Distal pancreatectomy for body-tail pancreatic cancer: is there a role for celiac axis resection?

BACKGROUND/AIMS: Body-tail pancreatic cancer is an aggressive disease with a low resectability rate and a poor prognosis. Celiac axis invasion usually contraindicates resection. The aim of this study was to analyze the feasibility of distal pancreatectomy (DP) with celiac axis resection (DP-CAR) for locally advanced body-tail pancreatic cancer. METHODS: All DPs performed between January 1989 and December 2007 were considered. DP and DP-CAR were reviewed for pre-, intra- and postoperative data. An extensive, detailed literature review on DP and DP-CAR was also performed. RESULTS: DP was performed in 49 of our patients, and 745 cases were retrieved from the literature. The overall morbidity and mortality rates were 32.0 and 3.0%, respectively. We performed DP-CAR in 5 patients with no mortality but 80% morbidity. A further 90 patients were retrieved from the literature. Arterial reconstruction was needed in 1/5 of our patients and in 13/90 of patients in the literature. Collaterals from superior mesenteric artery maintained adequate hepatic artery blood flow in the remaining 81 patients. The overall morbidity and mortality rates were 40.6 and 2.1%, respectively. The median survival ranged between 4.5 and 25 months after DP and was 13 months after DP-CAR. CONCLUSIONS: DP-CAR improves resectability without increasing the mortality rate. The complication rate after DP-CAR was higher than after DP, but still within the range of extended DP. DP-CAR should be considered for the inclusion among the 'extended' procedures for the treatment of body-tail pancreatic cancers invading the celiac axis. and IAP.

Quality of Life After Elective Laparoscopic Sigmoidectomy for Symptomatic Uncomplicated Diverticular Disease.

INTRODUCTION: Symptomatic uncomplicated diverticular disease (SUDD) is characterized by abdominal pain and altered bowel function and may affect quality of life. When symptoms are severe and conservative therapy is ineffective, surgical intervention becomes an option. OBJECTIVE: This study aims to investigate quality of life after elective sigmoidectomy for patients affected by SUDD. MATERIALS AND METHODS: Retrospective multicenter review of consecutive patients affected by SUDD that underwent elective laparoscopic sigmoidectomy from January 2015 to March 2018. SUDD was defined as the presence of diverticula with persistent localized pain and diarrhea or constipation without macroscopic inflammation. Quality of life was investigated using the Gastrointestinal Quality of Life Index questionnaire at baseline, and at 6 and 12 months after surgery. Readmissions, unplanned clinical examination, mesalazine resumption, and emergency department visit for abdominal symptoms were recorded. RESULTS: Fifty-two patients were included in the analysis. Gastrointestinal Quality of Life Index score at 6 months from surgery did not statistically differ from baseline (96±10.2 vs. 89±11.2; P>0.05), while patients reported a better quality of life at 12 months after surgery (109±8.6; P<0.05). Within the first year of follow-up, 3 patients (5.8%) were readmitted for acute enteritis, 8 patients (15.4%) had emergency room access for abdominal pain, and 8 patients had unplanned outpatients' medical examinations for referred lower abdominal pain and bowel changes. Mesalazine was resumed in 17.3% of patients. CONCLUSION: Elective laparoscopic sigmoidectomy for SUDD is safe and effective in improving quality of life, although in some cases symptoms may persist.

Postoperative pancreatic fistulas: preventing severe complications and reducing reoperation and mortality rate.

BACKGROUND: Postoperative pancreatic fistula (POPF) is responsible for severe complications and death in patients who underwent pancreatic surgery. The reported success rate of conservative treatment is around 80%. Therefore up to 20% of patients usually need surgical treatment that can be repeated in some. Uncontrolled sepsis and massive hemorrhage are the main causes for mortality in this setting. METHOD: Four hundred forty-five patients underwent surgery for pancreatic diseases (January 1993-August 2007); 70 of them developed a POPF. An early aggressive treatment based on interventional radiology was applied to all patients. The drain's track and/or percutaneous approach was used to insert catheters into the peripancreatic fluid collection/s or abscess/es. The position of catheters was verified at least once a week. Surgery was performed in case of failure of conservative approach. RESULTS: Conservative treatment (approach by drain's track in 49, percutaneous in 16, mixed in 2) was successful in 67 patients. A patient under dialysis had the drains inserted during an emergency surgery for peritonitis 6 days after surgery; a second patient underwent repeated surgical debridement, and a third patient underwent a procedure on the abdominal wall to separate a POPF from a colonic fistula. No patient with diagnosed POPF died. CONCLUSIONS: Early aggressive interventional radiology allowed managing conservatively 95.7% of POPF preventing severe complications and avoiding death.

Metastasis to the pancreas from colorectal cancer: is there a place for pancreatic resection?

PURPOSE: Pancreatic metastases from colorectal cancer are very rare, and the possible benefit of surgical treatment is not clearly defined. This study was designed to evaluate the outcome of patients undergoing pancreatic resection for metastatic colorectal cancer to the pancreas. METHODS: Nine patients underwent pancreatic resection for metastatic colorectal cancer between January 1980 and December 2006. The primary cancers were colon (n = 7) and rectal carcinoma (n = 2). The median interval between primary treatment and detection of pancreatic metastases was 32.5 months. In three cases pancreatic metastases were synchronous with the primary tumor. RESULTS: Five patients underwent pancreaticoduodenectomy, and four underwent distal pancreatectomy. A left lateral liver section and three colon resections were simultaneously performed in four patients. There was no postoperative mortality, and only two patients experienced complications. Survival averaged 19.8 (median, 17.0; range, 5-30) months: seven patients died of metastatic disease, one for unrelated disease after five months, and one is alive with liver metastases 30 months after surgery. CONCLUSION: Surgical resection can be performed safely in patients with isolated pancreatic metastases from colorectal cancer and in selected patients with associated extrapancreatic disease. Although long-term survival is rare, surgery should be included, whenever possible, in the multimodality approach to this disease.

Laparoscopic Approach to Large Bowel Neoplastic Obstruction After Self-Expandable-Metal-Stent (SEMS) Placement.

Endoscopic self-expandable metal stent (SEMS) placement as a bridge to surgery in large bowel neoplastic obstruction is an alternative to emergency surgery for the obstructive colorectal neoplasms. This study aims to analyze postoperative and long-term outcomes in a series of patients who underwent laparoscopic colorectal resection after SEMS placement. The analysis, after the stratification based on the time elapsed between the onset of the occlusive symptoms and the SEMS positioning, revealed an interesting result, with lower mortality for patients who underwent the procedure within 24 hours of hospitalization (P=0.0159). This trend may indicate the need to reduce the endoscopic time schedules as much as possible, even if an emergency procedure is needed. The laparoscopic approach, after stent placement as bridge therapy, can be a safe alternative to emergency surgery, if the procedure is precociously applied.

Aggressive behaviour of solid-pseudopapillary tumor of the pancreas in adults: a case report and review of the literature.

Solid-pseudopapillary tumor (SPT) is a rare neoplasm of the pancreas that usually occurs in young females. It is generally considered a low-grade malignant tumor that can remain asymptomatic for several years. The occurrence of infiltrating varieties of SPT is around 10%-15%. Between 1986 and 2006, 282 cystic tumors of the pancreas were observed. Among them a SPT was diagnosed in 8 patients (2.8%) with only one infiltrating variety. This was diagnosed in a 49-year-old female 13 years after the sonographic evidence of a small pancreatic cystic lesion interpreted as a pseudocyst. The tumor invaded a long segment of the portal-mesenteric vein confluence, and was removed with a total pancreatectomy, resection of the portal vein and reconstruction with the internal jugular vein. Histological examination confirmed the R-0 resection of the primary SPT, although a vascular invasion was demonstrated. The postoperative course was uneventful, but 32 mo after surgery the patient experienced diffuse liver metastases. Chemotherapy with different drugs was started. The patient is alive and symptom-free, with stable disease, 75 mo after surgery. Twenty-five patients with invasion of the portal vein and/or of mesenteric vessels were retrieved from the literature, 16 recent patients with tumor relapse after potentially curative resection were also retrieved. The best treatment remains a radical resection whenever possible, even in locally advanced or metastatic disease. The role of chemotherapy, and/or radiotherapy, is still to be defined.

Complications after gastrectomy for cancer: Italian perspective.

Surgery for gastric cancer is associated with significant major morbidity and an estimated mortality rate of about 5%. A reliable comparison of post-operative outcomes is hampered by the lack of a clear, universally recognized, definition of the most frequent complications. This paper reports the final results of a project launched by the Italian Research Group for Gastric Cancer in September 2015, whose goal was to propose a comprehensive list of surgical-related, gastric cancer-specific complications, with their definitions. The project was carried out through a multicentric, mainly web-based, consensus of experts. The proposed list, following assessment and validation by a group of experts of the European Chapter of the International Gastric Cancer Association, will form the basis for implementing a "Complications Recording Sheet" that can be disseminated worldwide for proper and reliable post-operative assessment.

Uncommon Case of a Post-Traumatic Portal Vein Pseudoaneurysm Treated with Percutaneous Transhepatic Stent Grafting.

We describe a man who presented with a traumatic portal vein pseudoaneurysm, which was subsequently managed with a percutaneous transhepatic stent graft. This case demonstrates a rarely seen condition in the traumatic population and a novel management strategy, which should be considered in the management of this challenging injury.
