Complete Traumatic Rupture of the Pancreas by a Horse Saddle: A Case Report.

Pancreatic trauma is one of the least observed diagnoses in the emergency room, much less in pediatric emergencies. Any cause of direct abdominal blunt trauma can cause it. With only a few cases presented in the literature, horse accidents have been associated with this complication, but it has been never seen in literature as a case where the horse-riding saddle is the one causing the pancreatic trauma, until now. Emphasizing the importance of an early diagnosis is the key point, but more importantly, to highlight that the correct diagnostic approach will grant the opportunity for a lesion in the main pancreatic duct to be identified, which will allow a timely surgical approach, increasing overall survival rates and decreasing morbidity in these patients. Here lies the importance of not only utilizing a specific study, such as a computerized tomography (CT) scan to evaluate abdominal trauma but also using other image studies that are better suited for pediatric patients, such as magnetic resonance image (MRI) with cholangiopancreatography (MRCP).

Management of Blunt Pancreatic Trauma in Children: A Persistent Controversy-Case Report and Comprehensive Literature Review.

Blunt pancreatic injury (BPI) is relatively uncommon in children, and is associated with relatively high morbidity and mortality, especially if diagnosis is delayed. The aim of this report is to review the literature regarding controversial questions in the early diagnosis and management of pediatric BPI. A representative case of blunt pancreatic trauma in a six-year-old girl with delayed diagnosis and intraoperative and postoperative complications was described. A systematic search of databases and the grey literature in Scopus and Web of Science using relevant keywords was conducted. A total of 26 relevant articles published in last 5 years were found in PubMed. Although early CT performance is considered part of initial pancreatic trauma workup, the sensitivity of CT for detecting main pancreatic duct injuries in children is relatively low. MRCP and ERCP (if available) are useful for assessing ductal injury and should be performed when the status of the pancreatic duct is unclear on the CT. Most patients with low-grade pancreatic damage may be treated conservatively. Although surgery involving distal pancreatectomy remains the preferred approach for most children with high-grade pancreatic injury, there is growing evidence to suggest that non-operative management (NOM) is safe and effective. Most pancreatic pseudo cysts following NOM had relatively mild complications, and most resolved spontaneously. For those children who do require surgery, a conservative operative approach with the least risk is advocated. In conclusion, the optimal management for pediatric pancreatic trauma is controversial. Further clinical trials are required to generate clinical practice guidelines on pancreatic trauma in a child population.

The Broad Spectrum of Paediatric Pancreatic Disease: A Single-center 26-years Retrospective Review.

BACKGROUND: Paediatric pancreatic pathology and its management is rarely described. We present our experience. METHODS: A retrospective case-note review of all patients with pancreatic disease from 1995 to 2021 was completed. Data are quoted as median (range). RESULTS: Two hundred and twelve patients were identified with 75.9% presenting with pancreatitis. Referrals for pancreatitis increased during the study period and affected a wide age range (2 months-15.6 years). Acute pancreatitis (n = 118) (age 10.6 (0.18-16.3) years). The most common causes were idiopathic (n = 60, 50.8%) and biliary (n = 28, 23.8%). About 10% required treatment for complications or underlying biliary causes. Recurrent pancreatitis (n = 14) (11.6 (0.3-14.3) years). The most common cause was hereditary pancreatitis (n = 6, 42.9%). One patient required endoscopic drainage of pseudocyst. Chronic pancreatitis (n = 29) (16 (0.38-15.5) years). The underlying diagnosis was idiopathic (n = 14, 48.4%) or hereditary pancreatitis (n = 10, 34.5%). 13 patients required active management, including pancreaticojejunostomies (n = 5). Blunt Trauma (n = 34) was managed conservatively in 24 (70.5%). 6 patients required open surgery, but 4 were managed by either endoscopy or interventional radiology. Pancreatic tumours (n = 13) presented at 11.2 (2.3-16) years. Pathology included pancreaticoblastomas (n = 3), solid pseudopapillary tumours (n = 3), neuroendocrine tumours (n = 2), acinar cell cystadenoma (n = 1), intraductal papillary mucinous neoplasm (n = 1), pancreatic insulinoma (n = 1), pancreatic ductal adenocarcinoma (n = 1), and embryonal rhabdomyosarcoma (n = 1). OTHERS (N = 4): Pancreatic cyst (n = 3) and annular pancreas (n = 1). CONCLUSION: Paediatric pancreatic disease spans a wide spectrum of both benign and malignant disease and benefits from access to specialist medical, surgical, endoscopic, and interventional radiology expertise. Referrals for paediatric pancreatitis are increasing, but aetiology is different to that seen in adults. LEVEL OF EVIDENCE: IV.

Evaluation of the Blunt Pancreatic Injury, a Long-Term Tertiary Care Center Study: An Original Research.

Introduction: Pancreatic trauma is uncommon and challenging to diagnose. Contrarily, severe injuries to the kidney, spleen, and liver are frequent and typically easy to detect with imaging methods. Pancreas injuries can cause a significant amount of morbidity and mortality. Reviewing the institution's experience with this rather infrequent injury was the goal of this study. Materials and Method: The patients' records were collected from the data records at the tertiary care center for patients who had pancreatic damage and were followed up for a year. The American Association for the Surgery of Trauma pancreatic damage grade scores were assigned to each patient using the radiologic and surgical findings. Clinical examination and CT results were predominantly used to make the diagnosis in patients who underwent non-operative treatment. The data are presented as descriptive statistics. Results: Only 2.2% of the total cases that presented to the trauma center were finalized as pancreatic injuries. Trauma to the abdomen was seen in nearly half the cases brought. Most of the subjects in pancreatic injuries were in grade 3. Mortality was noted maximum for the grade 3 and 4 cases. Conclusions: While high-grade pancreatic injury almost always requires an operational intervention, low-grade pancreatic injury with an intact main pancreatic duct may be effectively handled non-operatively. When possible, distal pancreatectomy with spleen preservation is the ideal procedure for distal pancreatic trans-action. A patient who is hemodynamically stable with complex pancreaticoduodenal damage, which is related to a high death rate, should undergo Whipple resection.

Initial suction drainage decreases severe postoperative complications after pancreatic trauma: A cohort study.

BACKGROUND: Few studies have addressed the question of which drain types are more beneficial for patients with pancreatic trauma (PT). AIM: To investigate whether sustained low negative pressure irrigation (NPI) suction drainage is superior to closed passive gravity (PG) drainage in PT patients. METHODS: PT patients who underwent pancreatic surgery were enrolled consecutively at a referral trauma center from January 2009 to October 2021. The primary outcome was defined as the occurrence of severe complications (Clavien-Dindo grade ≥ Ⅲb). Multivariable logistic regression was used to model the primary outcome, and propensity score matching (PSM) was included in the regression-based sensitivity analysis. RESULTS: In this study, 146 patients underwent initial PG drainage, and 50 underwent initial NPI suction drainage. In the entire cohort, a multivariable logistic regression model showed that the adjusted risk for severe complications was decreased with NPI suction drainage [14/50 (28.0%) vs 66/146 (45.2%); odds ratio (OR), 0.437; 95% confidence interval (CI): 0.203-0.940]. After 1:1 PSM, 44 matched pairs were identified. The proportion of each operative procedure performed for pancreatic injury-related and other intra-abdominal organ injury-related cases was comparable in the matched cohort. NPI suction drainage still showed a lower risk for severe complications [11/44 (25.0%) vs 21/44 (47.7%); OR, 0.365; 95%CI: 0.148-0.901]. A forest plot revealed that NPI suction drainage was associated with a lower risk of Clavien-Dindo severity in most subgroups. CONCLUSION: This study, based on one of the largest PT populations in a single high-volume center, revealed that initial NPI suction drainage could be recommended as a safe and effective alternative for managing complex PT patients.

A case series of emergency pancreaticoduodenectomies: What were their indications and outcomes?

Emergency pancreaticoduodenectomy (EPD) is a rarely performed operation. It is important to know the indications and outcomes of EPD to have a better understanding of its application in clinical practice. A review of eight consecutive cases of EPD was done. Between January 2003 and December 2021, 8 out of 370 patients (2.2%) in a single center received pancreaticoduodenectomy as emergency. There were six males and two females with a median age of 45.5 years. The indications were trauma in three patients, bleeding tumors in two patients, and one patient each in obstructing duodenal tumor, postoperative complication and post-endoscopic retrograde cholangiopancreatography (ERCP) complication. The median operative time and blood loss were 427.5 minutes and 1,825 mL, respectively. There was no operative mortality. Seven patients (87.5%) had postoperative complications. Three patients (37.5%) developed postoperative grade B pancreatic fistula. The median postoperative hospital stay was 23.5 days. Five patients were still alive while three patients survived for 13, 31, and 42 months after the operation. The causes of death were recurrent tumors in two patients, and sepsis in one patient. According to this case series, EPD is associated with increased morbidity and pancreatic fistula, but is still deserved in life-threatening situations and long-term survival is possible after EPD.

Clinical characteristics and long-term outcomes following pancreatic injury - An international multicenter cohort study.

Background: Trauma to the pancreas is rare but associated with significant morbidity. Currently available management guidelines are based on low-quality evidence and data on long-term outcomes is lacking. This study aimed to evaluate clinical characteristics and patient-reported long-term outcomes for pancreatic injury. Methods: A retrospective cohort study evaluating treatment for pancreatic injury in 11 centers across 5 European nations over >10 years was performed. Data relating to pancreatic injury and treatment were collected from hospital records. Patients reported quality of life (QoL), changes to employment and new or ongoing therapy due to index injury. Results: In all, 165 patients were included. The majority were male (70.9%), median age was 27 years (range: 6-93) and mechanism of injury predominantly blunt (87.9%). A quarter of cases were treated conservatively; higher injury severity score (ISS) and American Association for the Surgery of Trauma (AAST) pancreatic injury scores increased the likelihood for surgical, endoscopic and/or radiologic intervention. Isolated, blunt pancreatic injury was associated with younger age and pancreatic duct involvement; this cohort appeared to benefit from non-operative management. In the long term (median follow-up 93; range 8-214 months), exocrine and endocrine pancreatic insufficiency were reported by 9.3% of respondents. Long-term analgesic use also affected 9.3% of respondents, with many reported quality of life problems (QoL) potentially attributable to side-effects of opiate therapy. Overall, impaired QoL correlated with higher ISS scores, surgical therapy and opioid analgesia on discharge. Conclusions: Pancreatic trauma is rare but can lead to substantial short- and long-term morbidity. Near complete recovery of QoL indicators and pancreatic function can occur despite significant injury, especially in isolated, blunt pancreatic injury managed conservatively and when early weaning off opiate analgesia is achieved.

Establishment of a multifunctional impact system and a study of a pancreatic trauma model in rats based on controlling the injury area.

Background: At present, basic scientific research on pancreatic trauma is rare due to the lack of ideal animal models and modeling equipment for pancreatic trauma. Therefore, we intend to develop a multifunctional impact system with simple operation, diverse impact and accurate measurement and to establish a rat pancreatic trauma model based on injury area control by using the system. Methods: The impactor was designed based on the convenience of the impact energy acquisition, the diversity of the impact operation, and the precision of the impact strength parameter measurement by the team. The efficacy and stability/repeatability of the impactor were preliminarily evaluated. An impact head with different impact areas (3 cm2 and 6 cm2) of the impactor was used to squeeze the rat pancreas in the abdomen to form different injury areas under a pressure of 400 kPa. The efficacy features of this trauma model were evaluated by detecting the outcomes of pathology and biochemistry at 24 h after injury in the two groups. Furthermore, these changes were also evaluated at 6 h, 24 h, 48 h and 72 h after injury in the 3 cm2 trauma group. Result: Multifunctional impactors were successfully explored. The impact force was continuously adjustable with a range of 0-200 kg. The compression and extrusion stress ranges were continuously adjustable from 0 to 100 kg. System adjustment verified that the impactor had fine efficacy (P < 0.05) and stability/repeatability (P > 0.05). Compared with the control group, rats in the pancreatic trauma group with different injury areas exhibited obvious injuries (P < 0.05), and compared with the 3 cm2 trauma group, the 6 cm2 trauma group exhibited the more severe injury (P < 0.05). After modeling, the injury characteristics at different time points showed stable differences(P < 0.05). Conclusions: A rat pancreatic trauma model based on injury area control was successfully established using the impactor developed in this study. This model is simple, effective, controllable, and suitable for animal experimental research on pancreatic trauma.

Sequential changes in body composition and metabolic response after pancreatic trauma.

OBJECTIVES: Pancreatic trauma and subsequent pancreatic operation result in early pathophysiologic alterations. Understanding changes in energy expenditure and body composition is essential for optimal management. This study aims to observe changes in energy expenditure and body composition in patients during the early postoperative days (PODs) after pancreatic trauma. METHODS: This is a retrospective review of patients who underwent surgery for blunt pancreatic trauma in a single trauma center. Data of body composition by bioimpedance spectroscopy and energy expenditure by indirect calorimetry were collected and analyzed in patients during the early PODs. The association of body composition parameters with major complications was analyzed. RESULTS: Forty-one patients were included. Compared with POD-3, the total body water, extracellular water, fat-free mass, and skeletal muscle mass on POD-7 and -14 decreased significantly (all P < 0.05). The phase angle (PhA) increased significantly from POD-3 to -14 (P < 0.05). Resting energy expenditure was significantly higher than predicted and remained high throughout the study period. Over the 14-d study period, delivered energy was escalated to the level of resting energy expenditure. The PhA was significantly lower in patients with severe morbidity than in those without (3.6 [3.3-4.2] versus 4.5 [4.2-5.0]; P < 0.001). A multivariate analysis found that PhA was the independent variable for severe complications, with an odds ratio of 0.069 (95% CI, 0.011-0.427; P = 0.004). The predictive ability of PhA revealed an area under the receiver operating characteristic curve of 0.837, with an optimal threshold of 4.23. CONCLUSIONS: Changes in body composition and hypermetabolism state were observed from POD-3 to -14 after pancreatic trauma. A postoperative value of PhA < 4.23 is associated with severe complications.

Diagnóstico y tratamiento del traumatismo de páncreas / Diagnosis and treatment of pancreatic trauma

El traumatismo pancreático es una entidad poco frecuente pero potencialmente mortal, del que es necesario un alto nivel de sospecha clínica. El diagnóstico precoz y la valoración de la integridad del conducto pancreático son relevantes, siendo la lesión ductal el principal predictor de morbimortalidad. La mortalidad global es del 19%, ascendiendo al 30% en presencia de compromiso ductal. El abordaje diagnóstico y terapéutico es multidisciplinario (médico cirujano, radiólogo e intensivista). La analítica de laboratorio muestra elevación de las enzimas pancreáticas, siendo este hallazgo de baja especificidad. En pacientes con hemodinamia estable, la primera aproximación diagnóstica debe ser con una tomografía computarizada multidetector con contraste, recurriendo a la colangiopancreatografía endoscópica retrógrada o a la colangiorresonancia en caso de sospecha de lesión ductal. El propósito de esta revisión es analizar la etiopatogenia y fisiopatología del traumatismo pancreático, presentando su abordaje diagnóstico y terapéutico y sus complicaciones más frecuentes (AU)

Pancreatic trauma is a rare but potentially lethal entity which requires a high level of clinical suspicion. Early diagnosis and assessment of the integrity of the pancreatic duct are essential since ductal injury is a crucial predictor of morbimortality. Overall mortality is 19%, which can rise to 30% in cases of ductal injury. The diagnostic and therapeutic approach is multidisciplinary and guided by a surgeon, imaging specialist and ICU physician. Laboratory analysis shows that pancreatic enzymes are frequently elevated, which is a low specificity finding. In hemodynamically stable patients, the posttraumatic condition of the pancreas is firstly evaluated by the multidetector computed tomography. Moreover, in case of suspicion of ductal injury, more sensitive studies such as Endoscopic Retrograde Cholangiopancreatography or cholangioresonance are needed. This narrative review aims to analyze the etiopathogenesis and pathophysiology of pancreatic trauma and discuss its diagnosis and treatment. Also, the most clinically relevant complications will be summarized (AU)

Traumatic pancreas, kidney, liver, spleen, gastric and diaphragma rupture with enterothorax after blunt trauma caused by falling in an adolescent: a case report.

Injury of almost all intra-abdominal organs in blunt trauma without bone and brain injury is very rare. This is the case report of a 16-year-old adolescent with severe abdominal trauma who was hit on his abdomen by a falling maytree. After admission to a Level I trauma center, emergency room treatment according to ATLS and after this emergency surgery was performed. Blood coagulation diagnostics was done using thrombo-elastography and factors and blood products have been applied according to its results keeping guidelines in mind. Damage-control surgery stopped the bleeding, and he was admitted to ICU. After second and third look surgery, the abdomen was closed. Structured diagnostics and treatment were crucial in this case. The education of trauma surgeons should include general surgery skills. These skills and knowledge of blood coagulation diagnostics and therapy saved the patient's life in this case.

Pancreatoduodenectomía de urgencia. Revisión de 2 casos clínicos

Introducción: La pancreatoduodenectomía de urgencia (PDDU) es una cirugía reservada para lesiones graves pancreatoduodenales secundarias a trauma, lesiones inflamatorias o posterior a procedimientos endoscópicos. Objetivo: Describir dos casos clínicos en los que se realizó PDDU. Casos Clínicos: Se reportan 2 casos clínicos en los cuales se requirió una PDD. En el primer caso secundario a úlcera duodenal perforada que comprometía más del 50% del lumen asociado a biliperitoneo y fistula duodenal sin control; y en el segundo, a consecuencia de un trauma por herida de bala con perforación duodenal, íleon distal y desgarro de 1,5 cm en cabeza de páncreas. Discusión: En la actualidad no existe un consenso sobre las indicaciones de PPDU, sin embargo esta compleja cirugía representa una opción de tratamiento en pacientes bien seleccionados, cuando la cirugía de control de daños y los intentos de controlar la necrosis y fistulas duodenales han fracasado. Conclusión: El tratamiento de una lesión pancreática y duodenal compleja puede requerir PDDU. Sin embargo, en pacientes inestables se debe considerar una cirugía en dos tiempos por un equipo de cirujanos experimentados.

Introduction: Emergency pancreaticoduodenectomy (UPDD) is a surgery reserved for severe pancreaticoduodenal injuries secondary to trauma, inflammatory injuries or after endoscopic procedures. Aim: To describe two clinical cases in which PDDU was performed. Clinical Cases: 2 clinical cases are reported in which a PDDU was required. The first case was secondary to a perforated duodenal ulcer that compromised more than 50% of the lumen associated with biliperitoneum uncontrolled duodenal fistula; in the second one, as a consequence of a gunshot wound trauma with duodenal perforation, distal ileum and a 1.5 cm tear in the head of pancreas. Discussion: Currently there is no consensus on the indications for UPDD, however this complex surgery represents a treatment option in well-selected patients, when damage control surgery and attempts to control necrosis and duodenal fistulas have failed. Conclusión: Treatment of a complex pancreatic and duodenal injury may require pancreatoduodenectomy. However, in unstable patients, a two-stage surgery should be considered by an experienced surgical team.

Revisiting the Conundrum: A Case Report on Trauma Whipple's Pancreaticoduodenectomy.

Despite its rarity, pancreatic trauma is a serious condition because of its retroperitoneal location, association with other organ injuries, and complex bilio-vascular anatomy. Even less common are isolated pancreatic injuries. In grade four injuries, there is a debate over resectional vs. non-resectional management and appropriate treatment is particularly difficult. Here we discuss a patient with grade four pancreatic injury with pancreatic ascites presenting four days after the incident and traumatic pancreatitis. She underwent pylorus-preserving pancreatoduodenectomy and recovered well with acceptable morbidity.

Applying refined pancreaticogastrostomy techniques in pancreatic trauma.

We comment on a study titled "Feasibility and safety of "bridging" pancreaticogastrostomy for pancreatic trauma in Landrace pigs" in which ten pigs were randomized to either experimental "bridging" pancreaticogastrostomy (PG) or a control group with a routine mucosa-to-mucosa PG. At six months anastomoses had strictured and closed in both groups. The authors concluded that "bridging" PG is feasible and safe in damage control surgery during the early stage of pancreatic injury. In this letter we comment on the study design, specifically leaving a 2 cm gap between the pancreatic stump and the stomach and highlight the complexity of performing pancreatic anastomoses following trauma pancreaticoduodenectomy as to our experience in a high volume trauma centre. Our data emphasize that pancreatic anastomoses in trauma are complex procedures with significant postoperative morbidity and are best managed collaboratively by trauma and hepatopancreaticobiliary surgical teams with the required technical skills.

A Pragmatic Approach to Pancreatic Trauma: A Single-Center Experience From a Tertiary Care Center.

Introduction Pancreatic trauma is rare and is usually associated with adjacent organ and vascular injuries, which adds to the high morbidity and mortality. In the American Association for the Surgery of Trauma (AAST) pancreatic trauma (PT) grading system, the higher grades are a composite of less and more severe extents of injuries. We hereby present an observational study of PT with management based on an indigenous algorithmic approach. Our protocol incorporating both the extent of disruption of the main pancreatic duct (MPD) and its amenability to interventions (endoscopic, radiological, or surgical) is pragmatic. Methods Ours is a retrospective observational study of 28 consecutive cases of PT, done over a three-year period in an academic institution, by an expert Surgical Gastroenterology unit. All patients diagnosed with PT on a contrast abdominal CT scan were included. After stabilization, they were stratified and managed according to an indigenous protocol. The primary outcome measure was treatment success in terms of recovery. The secondary outcome measure was morbidity of any form. Results One patient with Grade 1 PT was operated on for associated hollow viscus injury. Two patients with AAST Grade 2 and two patients with AAST Grade 3 injury were managed successfully without surgery. Twelve of 21 patients with Grade 3 PT underwent Kimura's splenic vessel preserving distal pancreatectomy. Distal pancreatectomy with splenectomy and central pancreatectomy with Roux-en-Y pancreaticojejunostomy (PJ) was done for 7/21 and 2/21 patients, respectively, with Grade 3 PT. Two with Grade 5 injury underwent trauma Whipple. The overall mortality and morbidity rates in our series were 15.7% and 64%, respectively. Conclusion The pathogenesis in PT is a dynamic process and shows temporal evolution. These patients require serial and periodical clinical and radiological monitoring, especially in those managed conservatively initially. PT can be low or high grade. Patients with isolated low-grade PT can be managed according to the standard step-up approach for acute pancreatitis. A carefully selected subgroup of patients with partial MPD disruption either in the head or body of the pancreas can be managed by endotherapy. Complete distal parenchymal transections require early surgery tailored to individual patients in the form of either splenic vessel preserving distal pancreatectomy (SPDP) or distal pancreatectomy with splenectomy (DP+S). Damage control surgery is the dictum in unstable patients with Grades 4 and 5 injuries not responding to resuscitative measures. A trauma Whipple can be done in a carefully selected subgroup of stable patients with proximal massive disruptions in an experienced hepato-pancreatico-biliary (HPB) unit.

A case-control study of risk factors for survival after laparotomy in patients with pancreatic trauma.

BACKGROUND: Pancreatic trauma results in significant morbidity and mortality. However, few studies have investigated the postoperative prognostic factors in patients with pancreatic trauma. MATERIAL AND METHODS: A retrospective study was conducted on consecutive patients with pancreatic trauma who underwent surgery in a national referral trauma center. Clinical data were retrieved from the electronic medical system. Univariate and binary logistic regression analyses were performed to identify the perioperative clinical parameters that may predict the factors of mortality of the patients. RESULTS: A total of 150 patients underwent laparotomy due to pancreatic trauma during the study period. 128(85.4%) patients survived and 22 (14.6%) patients died due to pancreatic injury (10 patients died of recurrent intra-abdominal active hemorrhage and 12 died of multiple organ failure). Univariate analysis showed that age, hemodynamic status, and injury severe score (ISS) as well as postoperative serum levels of C-reactive protein (CRP), procalcitonin, albumin, creatinine and the volume of intraoperative blood transfusion remained strongly predictive of mortality (P < 0.05). Binary logistic regression analysis showed that the independent risk factors for prognosis after pancreatic trauma were age (P = 0.010), preoperative hemodynamic instability (P = 0.015), postoperative CRP ≥154 mg/L (P = 0.014), and postoperative serum creatinine ≥177 µmol/L (P = 0.027). CONCLUSIONS: In this single-center retrospective study, we demonstrated that preoperative hemodynamic instability, severe postoperative inflammation (CRP ≥154 mg/L) and acute renal failure (creatinine ≥177 µmol/L) were associated with a significant risk of mortality after pancreatic trauma.

Primary Repair of Traumatic Complete Pancreatic Rupture.

Isolated pancreatic injury with transection of the pancreatic duct is generally treated with pancreatic resection, but the optimal management is not based on high-level evidence. Herein, we report a case of primary repair of complete rupture of the pancreas and pancreatic duct after a blunt abdominal trauma and a review of the literature. A 33-year-old patient had an isolated pancreatic injury after blunt abdominal trauma. At laparotomy, an even transection was found with minimal necrosis and tissue loss and an end-to-end anastomosis of the duct and the parenchyma with omental patch was performed. Patient's postoperative course was complicated by a 6 cm pseudocyst and a low output pancreatic fistula which did not require any intervention and were self-limited. In the literature, 17 cases with primary repair of similar grade IV pancreatic injuries have been reported. Postoperative complications included mostly fistulas and pseudocysts.

Feasibility and safety of "bridging" pancreaticogastrostomy for pancreatic trauma in Landrace pigs.

BACKGROUND: In recent years, we created and employed a new anastomosis method, "bridging" pancreaticogastrostomy, to treat patients with extremely severe pancreatic injury. This surgery has advantages such as short length of surgery, low secondary trauma, rapid construction of shunts for pancreatic fluid, preventing second surgeries, and achieving good treatment outcomes in clinical practice. However, due to the limited number of clinical cases, there is a lack of strong evidence to support the feasibility and safety of this surgical procedure. Therefore, we carried out animal experiments to examine this procedure, which is reported here. AIM: To examine the feasibility and safety of a new rapid method of pancreaticogastrostomy, "bridging" pancreaticogastrostomy. METHODS: Ten Landrace pigs were randomized into the experimental and control groups, with five pigs in each group. "Bridging" pancreaticogastrostomy was performed in the experimental group, while routine mucosa-to-mucosa pancreaticogastrostomy was performed in the control group. After surgery, the general condition, amylase levels in drainage fluid on Days 1, 3, 5, and 7, fasting and 2-h postprandial blood glucose 6 mo after surgery, fasting, 2-h postprandial peripheral blood insulin, and portal vein blood insulin 6 mo after surgery were assessed. Resurgery was carried out at 1 and 6 mo after the former one to examine the condition of the abdominal cavity and firmness and tightness of the pancreaticogastric anastomosis and pancreas. RESULTS: After surgery, the general condition of the animals was good. One in the control group did not gain weight 6 mo after surgery, whereas significant weight gain was present in the others. There were significant differences on Days 1 and 3 after surgery between the two groups but no differences on Days 5 and 7. There were no differences in fasting and 2-h postprandial blood glucose and fasting and 2-h insulin values of postprandial peripheral blood and portal vein blood 6 mo after surgery between the two groups. One month after surgery, the sinus tract orifice/anastomosis was patent in the two groups. Six months after surgery, the sinus tract orifice/anastomosis was sealed, and pancreases in both groups presented with chronic pancreatitis. CONCLUSION: "Bridging" pancreaticogastrostomy is a feasible and safe a means of damage control surgery during the early stage of pancreatic injury.

Pancreas-Preserving Total Duodenectomy: A Systematic Review.

BACKGROUND: The management of the pancreas in patients with duodenal trauma or duodenal tumors remains a controversial issue. Pancreas-preserving total duodenectomy (PPTD) requires a meticulous surgical technique. The most common indication is familial duodenal adenomatous polyposis (FAP). The aims of this study are to carry out a systematic review of the literature on the indications for PPTD and to highlight the risks and benefits compared with other more aggressive procedures. SUMMARY: A systematic literature review was performed following PRISMA recommendations of studies published in PubMed, Embase, and Cochrane library until May 2019. Thirty articles describing 211 patients were chosen. The mean age was 48 years. The surgical indication in 75% of patients was FAP. The mean operating time was 329 min and mean intraoperative bleeding 412 mL. Postoperative morbidity rate was 49.7% (76% Clavien-Dindo 97.8%. Key Messages: PPTD is indicated for patients with benign and premalignant duodenal lesions without involvement of the pancreatic head. It is a feasible procedure offering an alternative to other more aggressive procedures in selected patients. Mortality is below 1.5%.
