Endoscopic repair of duodenal perforations, a scoping review.

BACKGROUND: There is a discrepancy in the surgical and endoscopic literature for managing duodenal perforations. Although often managed conservatively, surgical repair is the standard treatment for duodenal perforations. This contrasts with the gastroenterology literature, which now recommends endoscopic repair of duodenal perforations, which are more frequently iatrogenic from the growing field of advanced endoscopic procedures. This study aims to provide a scoping review to summarize the current literature content and quality on endoscopic repair of duodenal perforations. METHODS: The protocol for performing this scoping review was outlined by the Joanna Briggs Institute. All studies that reported primary outcomes of patients who had undergone endoscopic repair of duodenal perforations before February 2022, regardless of perforation etiology or repair type were reviewed, with studies after 1999 meeting inclusion criteria. The study excluded articles that did not report clinical outcomes of endoscopic repair, articles that did not describe where in the gastrointestinal tract the endoscopic repair occurred, pediatric patients, and animal studies. RESULTS: 7606 abstracts were screened, with 474 full articles reviewed and 152 studies met inclusion criteria. 560 patients had duodenal perforations repaired endoscopically, with a technical success rate of 90.4% and a survival rate of 86.7%. Most of these perforations (74.5%) were iatrogenic from endoscopic procedures or surgery. Only one randomized control trial (RCT) was found, and 53% of studies were case reports. CONCLUSION: These results suggest that endoscopic repair could emerge as a viable first-line treatment for duodenal perforation and highlight the need for more high-quality research in this topic.

Pancreaticoduodenectomy in high-grade pancreatic and duodenal trauma.

INTRODUCTION: High-grade pancreaticoduodenal injuries are highly morbid and may require complex surgical management. Pancreaticoduodenectomy (Whipple procedure) is sometimes utilized in the management of these injuries, but guidelines on its use are lacking. This paper aims to present our 14-year experience in management of high-grade pancreaticoduodenal injuries at our busy, urban trauma center. METHODS: A retrospective review was performed on patients (ages >15 years) presenting with high-grade (AAST-OIS Grades IV and V) injuries to the pancreas or duodenum at our Southeastern Level 1 trauma center. Inclusion criteria included high-grade injury and requirement of Whipple procedure based on surgeon discretion. Patients were divided into two groups: (1) those who underwent Whipple procedures during the index operation and (2) Whipple candidates. Whipple candidates included patients who received Whipples in a staged fashion or who would have benefited from the procedure but either died or were salvaged to another procedure. Demographics, injury patterns, management, and outcomes were compared. Primary outcome was survival to discharge. RESULTS: Of 66,272 trauma patients in this study period, 666 had pancreatic or duodenal injuries, and 20 met inclusion criteria. Of these, 6 had Whipples on the index procedure and 14 were Whipple candidates (among whom 7 had staged Whipples, 6 died before completing a Whipple, and 1 was salvaged). Median (IQR) age was 28 (22.75-40) years. Patients were 85 % male, 70 % Black. GSWs comprised 95 % of injuries. All patients had at least one concomitant injury, most commonly major vascular injury (75 %), colonic injury (65 %), and hepatic injury (60 %). In-hospital mortality among Whipple patients was 15 %. CONCLUSIONS: Complex pancreaticoduodenal injuries requiring pancreaticoduodenectomy are rare but life-threatening. In such patients, hemorrhage was the leading cause of death in the first 24 h. Approximately half underwent damage control surgery with staged Whipple Procedures. However, pancreaticoduodenectomy at the initial operation is feasible in highly selective patients, depending on the extent of injury, physiologic status, and resuscitation.

Use of jejunal serosal patch and pyloric exclusion in the management of complex duodenal injury.

BACKGROUND: Duodenal injuries are relatively rare but remain a management challenge with a high incidence of postoperative complications. Guidelines from the World Society of Emergency Surgery and American Association for the Surgery of Trauma favour a primary repair for less-complex injuries, but the management of more complex duodenal trauma remains controversial with varying techniques supported, including pyloric exclusion, omental or jejunal patch closure, gastrojejunostomy and pancreatoduodenectomy. We describe the techniques used in one case of complex duodenal trauma. TECHNIQUE: The duodenum is approached via a standard laparotomy with Kocherisation. Primary repair of the duodenal perforations is performed using a 3/0 polydioxanone suture (PDS), followed by mobilisation of a loop of mid-jejunum against the area of duodenal trauma over the primary repair as a jejunal serosal patch. The antimesenteric jejunal serosal border is sutured to the serosa of the duodenum (serosa only) using a 3/0 PDS. Pyloric exclusion is then performed through an anterior gastrostomy, to control the volume of gastric juice entering the duodenum. The pylorus is sutured closed using an absorbable suture followed by closure of the anterior gastrostomy using a GIA stapling device.

Pancreas-sparing partial duodenectomy as an alternative to emergency pancreaticoduodenectomy for a major duodenal perforation: a case report.

A 71-year-old woman underwent endoscopic submucosal dissection for early duodenal cancer at the second portion of the duodenum and developed acute peritonitis due to delayed duodenal perforation. Emergency laparotomy was performed. A huge perforation formed at the descending duodenum without ampulla involvement. Pancreas-sparing partial duodenectomy (PPD) with gastrojejunostomy was performed (250 min operative time) with 50 mL of intraoperative blood loss. She required intensive care for 3 days and was discharged on postoperative day 21 with no severe complications. Emergency treatment for a major duodenal injury or perforation remains challenging because of high morbidity and mortality. An appropriate treatment should be considered according to the nature of the defect. Although PPD is an acceptable procedure for patients with a duodenal neoplasm, its use in emergency surgery is rarely reported. PPD is more reliable than primary repair or anastomosis using a jejunal wall, and less invasive than pancreaticoduodenectomy, for emergency treatment. We performed PPD in this patient because the duodenal perforation was too large to reconstruct and did not involve the ampulla. PPD can be a safe and feasible alternative surgical procedure to pancreaticoduodenectomy for a major duodenal perforation, especially in patients with a duodenal perforation that does not involve the ampulla.

Imaging spectrum of non-neoplastic and neoplastic conditions of the duodenum: a pictorial review.

Given its crucial location at the crossroads of the gastrointestinal tract, the hepatobiliary system and the splanchnic vessels, the duodenum can be affected by a wide spectrum of abnormalities. Computed tomography and magnetic resonance imaging, in conjunction with endoscopy, are often performed to evaluate these conditions, and several duodenal pathologies can be identified on fluoroscopic studies. Since many conditions affecting this organ are asymptomatic, the role of imaging cannot be overemphasized. In this article we will review the imaging features of many conditions affecting the duodenum, focusing on cross-sectional imaging studies, including congenital malformations, such as annular pancreas and intestinal malrotation; vascular pathologies, such as superior mesenteric artery syndrome; inflammatory and infectious conditions; trauma; neoplasms and iatrogenic complications. Because of the complexity of the duodenum, familiarity with the duodenal anatomy and physiology as well as the imaging features of the plethora of conditions affecting this organ is crucial to differentiate those conditions that could be managed medically from the ones that require intervention.

Contemporary Management of Traumatic Duodenal Injuries.

BACKGROUND: Traumatic duodenal injury is a rare, potentially devastating condition with challenging management decisions. Contemporary literature on operative management of duodenal injury is lacking. The purpose of this study is to assess optimal management strategies based on outcomes of patients with traumatic duodenal injury at a single trauma center. METHODS: A retrospective study of patients with traumatic duodenal injury from 2013-2020 at a level 1 trauma center was performed. Patient demographics, grade of injury as noted on CT scan or intraoperatively, surgical procedure(s) performed, and resultant outcomes were extracted. RESULTS: After excluding one patient due to death on arrival, 23 patients met inclusion criteria. Injuries consisted of grade 1 (n = 7), grade 2 (n = 2), grade 3 (n = 12), and grade 5 (n = 2); there were no grade 4 injuries. Patients were predominantly male (83%) with a median age of 30 years old. Nineteen patients (82%) underwent surgery. Four of nine patients (44%) with grade 1/2 injuries had hematomas and were managed non-operatively. The remaining five patients (56%) with grade 1/2 injuries underwent operation, which included primary repair (n = 3), duodenal exclusion (n = 1), and periduodenal drainage (n = 1). Of 12 patients with grade 3 injury, 6 underwent primary repair and 6 underwent resection. Three patients who underwent primary repair and one who underwent resection developed a duodenal leak. All patients with grade 5 injury (n = 2) underwent pancreaticoduodenectomy. CONCLUSION: Grade 1 and 2 duodenal hematomas can be managed non-operatively, while lacerations require operative repair. Outcomes may be better following resection in patients with grade 3 injury.

Perforación duodenal por barotrauma durante colangiopancreatografía retrógrada endoscópica: caso clínico / Duodenal perforation due to barotrauma during endoscopic retrograde cholangiopancreatography: clinical case

Resumen Introducción: La perforación duodenal secundaria a la colangiopancreatografía retrógrada endoscópica (CPRE) es una complicación infrecuente y más aún cuando su mecanismo lesional es por barotrauma. La inyección de aire a alta presión produce un neumoretroperitoneo, cuya extensión y evolución lesional es incierta. Caso Clínico: Se comunica el caso de un hombre joven que sufrió una perforación duodenal durante una CPRE, su manejo quirúrgico y evolución. Discusión: El diagnóstico clínico-imagenológico suele ser precoz y claro si se detecta la lesión durante el procedimiento. El manejo terapéutico conservador o quirúrgico de esta entidad depende de varios factores que se analizan en el presente estudio.

Introduction: Duodenal perforation during endoscopic retrograde cholangiopancreatography (ERCP) is a rare complication and even more if the mechanism of injury is secondary to barotrauma. The injection of high-pressure-air produces a pneumo-retroperitoneum, the extent and lesional evolution of which is uncertain. Clinical Case: We report the case of a young man who suffered a duodenal perforation during an ERCP, his surgical management and evolution. Discussion: The clinical-imaging diagnosis is usually early and clear if the lesion is detected during the procedure. Its conservative or surgical management will depends on several factors that are analyzed in the present study.

Damage control in penetrating duodenal trauma: less is better - the sequel.

The overall incidence of duodenal injuries in severely injured trauma patients is between 0.2 to 0.6% and the overall prevalence in those suffering from abdominal trauma is 3 to 5%. Approximately 80% of these cases are secondary to penetrating trauma, commonly associated with vascular and adjacent organ injuries. Therefore, defining the best surgical treatment algorithm remains controversial. Mild to moderate duodenal trauma is currently managed via primary repair and simple surgical techniques. However, severe injuries have required complex surgical techniques without significant favorable outcomes and a consequential increase in mortality rates. This article aims to delineate the experience in the surgical management of penetrating duodenal injuries via the creation of a practical and effective algorithm that includes basic principles of damage control surgery that sticks to the philosophy of "Less is Better". Surgical management of all penetrating duodenal trauma should always default when possible to primary repair. When confronted with a complex duodenal injury, hemodynamic instability, and/or significant associated injuries, the default should be damage control surgery. Definitive reconstructive surgery should be postponed until the patient has been adequately resuscitated and the diamond of death has been corrected.

El trauma de duodeno comúnmente se produce por un trauma penetrante que puede asociarse a lesiones vasculares y de órganos adyacentes. En el manejo quirúrgico se recomienda realizar un reparo primario o el empleo de técnicas quirúrgicas simples. Sin embargo, el abordaje de lesiones severas del duodeno es un tema controversial. Anteriormente, se han descrito técnicas como la exclusión pilórica o la pancreatoduodenectomía con resultados no concluyentes. El presente artículo presenta una propuesta del manejo de control de daños del trauma penetrante de duodeno, a través, de un algoritmo de cinco pasos. Este algoritmo plantea una solución para el cirujano cuando no es posible realizar el reparo primario. El control de daños del duodeno y su reconstrucción depende de una toma de decisiones respecto a la porción del duodeno lesionada y el compromiso sobre el complejo pancreatoduodenal. Se recomiendan medidas rápidas para contener el daño y se proponen vías de reconstrucción duodenal diferente a las clásicamente descritas. Igualmente, la probabilidad de complicaciones como fistula duodenales es considerable, por lo que proponemos, que el manejo de este tipo de fistulas de alto gasto se aborde por medio de una laparostomía retroperitoneal (lumbotomía). El abordaje del trauma penetrante de duodeno se puede realizar a través del principio "menos es mejor".

Traumatic duodenal injuries in children: a single-centre study.

BACKGROUND: Traumatic duodenal injuries in children are rare, and few studies have documented duodenal injuries in children, especially in Australasia. This study assessed the mechanism, investigations, management and outcomes of children (aged <16 years) with duodenal injuries. METHODS: Retrospective review was conducted over a 16-year period from a single paediatric trauma centre. RESULTS: Sixteen cases of duodenal injuries were identified: 15 cases of blunt duodenal injury and only one case of penetrating injury. Motor vehicular accidents were the most common cause of injury, followed by auto-pedestrian injuries and handlebar injuries. Only grade I and II injuries were identified. Computed tomography aided diagnosis in all cases of blunt duodenal injuries, especially given the variable nature of symptoms. Eight patients underwent laparotomy, of whom five required duodenal repair. Three patients underwent primary repair with omental patch, one patient underwent primary repair with gastrostomy and one patient underwent two-layered repair with t-tube duodenostomy. There were no delays in operative management within 24 h and no complications identified. CONCLUSION: In comparison to other paediatric trauma centres worldwide, the majority of duodenal injuries were low grade and attributed to blunt trauma. Computed tomography aided diagnosis in all cases of blunt duodenal injury. Primary repair of duodenal injuries was possible in the majority of cases requiring operative repair.

Duodenal Laceration Due to Blunt Trauma Caused by Horse Kick: A Case Report and Literature Review.

BACKGROUND Duodenal trauma usually consists of retroperitoneal lesions. Its management can be complicated by the location of the injury and difficulty in making an early diagnosis. Duodenal injuries are divided into blunt and penetrating trauma, and the possible results are hematoma, laceration, and devascularization. Duodenal lesions due to blunt trauma are usually accompanied by lesions of nearby organs. We present a rare case of a single duodenal laceration due to blunt abdominal trauma caused by a horse kick, along with a literature review. CASE REPORT A 13-year-old boy presented to our emergency department after being kicked by a horse in his abdomen. He was stable and complained of abdominal pain without any other specifications. Computed tomography imaging revealed a retropneumoperitoneum and free fluid in the abdominal cavity. The patient was taken for an emergency laparotomy, which showed a single duodenal laceration of the second and third portions of the duodenum. The laceration was repaired with a double-layer closure using monofilament 3-0 polypropylene suture. The patient recovered from his injuries and was well at his last follow-up. CONCLUSIONS This case highlights the possible outcomes of an innocent blunt trauma and the importance of early diagnosis for the best outcome of a duodenal laceration. It also identifies the dissociation between the patient's clinical presentation and his significant intra-abdominal injury.

Pancreaticoduodenal arterial hemorrhage following blunt abdominal trauma treated with transcatheter arterial embolization: Two case reports.

RATIONALE: Although surgery has been the standard treatment for pancreaticoduodenal trauma because of the complex anatomical relation of the affect organs, transcatheter arterial embolization (TAE) has recently been introduced as a safe and effective treatment. However, TAE for pancreaticoduodenal arterial hemorrhage (PDAH) can be challenging because it is difficult to localize the involved artery and to embolize the bleeding completely due to the abundant collateral channels of the pancreaticoduodenal artery (PDA). PATIENT CONCERNS: Herein, we report 2 cases of PDAH that occurred after falling down in case 1 and a pedestrian traffic accident in case 2. DIAGNOSES: Multidetector computed tomography scan revealed massive retroperitoneal hematoma with active extravasation of contrast media from the PDA without any duodenal perforation or advanced pancreatic injury in both patients. INTERVENTIONS: All patients were successfully treated using only TAE with a combination of microcoils and n-butyl cyanoacrylate (NBCA) in case 1, and only NBCA in case 2. OUTCOMES: There was no complication such as duodenal ischemia or pancreatitis. Laparotomy was not needed after TAE. LESSONS: In selective PDAH cases, TAE may be a reasonable alternative to emergency laparotomy. It is expected that a careful and repetitive approach, based on complete angiography and embolization with a permanent liquid embolic agent such as NBCA could increase the success rate of TAE.

Duodenal perforations secondary to a migrated biliary plastic stent successfully treated by endoscope: case-report and review of the literature.

BACKGROUND: Endoscopic retrograde biliary drainage (ERBD) is the most frequently performed procedure for treating benign or malignant biliary obstruction. Although duodenal perforations secondary to the biliary plastic stent are quite rare, they can be life-threatening. The treatment strategies for such perforations are diverse and continue to be debated. CASE PRESENTATION: We report three cases of duodenal perforation due to the migration of biliary plastic stents that were successfully managed using an endoscope. The three patients were admitted on complaints of abdominal pain after they underwent ERBD. Abdominal computerized tomography (CT) revealed migration of the biliary plastic stents and perforation of the duodenum. Endoscopy was immediately performed, and perforation was confirmed. All migrated stents were successfully extracted endoscopically by using snares. In two of the three cases, the duodenal defects were successfully closed with haemostatic clips after stent retrieval, and subsequently, endoscopic nasobiliary drainage tubes were inserted. After the endoscopy and medical treatment, all three patients recovered completely. CONCLUSIONS: Duodenal perforations due to the migration of biliary stents are rare, and the treatment strategies remain controversial. Our cases and cases in the literature demonstrate that abdominal CT is the preferred method of examination for such perforations, and endoscopic management is appropriate as a first-line treatment approach.

Pasteurized Chicken Egg Powder Stimulates Proliferation and Migration of AGS, RIE1, and Caco-2 Cells and Reduces NSAID-Induced Injury in Mice and Colitis in Rats.

BACKGROUND: Chicken eggs and bovine colostrum contain proteins possessing antimicrobial, immunoregulatory, and growth factor activity. The ability of eggs to influence gut defense and repair is largely unexplored. OBJECTIVE: We examined the effect of pasteurized spray-dried egg on gastrointestinal injury using cell culture and animal models and sought to determine whether adding colostrum provided extra benefit. METHODS: Egg alone, colostrum alone, and a 40:60 egg: colostrum combination were tested for proliferative (Alamar blue) and migratory (wounded monolayer) activity at 1 mg.mL-1 using human colon adenocarcinoma (Caco-2), human gastric cancer (AGS), and rat intestinal epithelioid-1 (RIE1) cells. Four groups of adult male C57BL/6 mice received 20 mg.kg-1.d-1 test products in drinking water for 7 d and indomethacin (85 mg.kg-1, administered subcutaneously) on day 7. Villus height and morphology were assessed. Three groups of adult male Sprague Dawley rats received 20 mg.kg-1.d-1 test product by gavage for 9 d and dextran sodium sulfate (DSS, 4% in drinking water) for the final 7 d. Histology, microscopic damage scoring, and myeloperoxidase were assessed. RESULTS: Egg or colostrum alone caused 3-fold increases in cell proliferation and migration (P < 0.05 compared with baseline). Heating the egg removed its bioactivity. Addition of neutralizing antibodies or tyrphostin showed that ovomucoid, ovalbumin, and the epidermal growth factor receptor mediated the effects of egg (all P < 0.05 compared with egg). Egg reduced shortening of villi caused by indomethacin in mice by 34% and reduced DSS-induced colonic damage in rats by 44-61% (P < 0.05 compared with DSS). Similar results were seen using colostrum alone. In each assay, the 40:60 combination gave improved results compared with the same dose of egg or colostrum alone (P < 0.05). CONCLUSIONS: Studies using AGS, RIE1, and Caco-2 cells, C57BL/6 mice, and Sprague Dawley rats showed protective effects of egg against gut injury. Enhanced results were seen if colostrum and egg were coadministered. Egg powder with or without colostrum may have therapeutic value for prevention and treatment of gut injuries.

Modified delta-shaped gastroduodenostomy consisting of linear stapling and single-layer suturing with the operator positioned between the patient's legs: A technique preventing intraoperative duodenal injury and postoperative anastomotic stenosis.

BACKGROUND: The drawback of the delta-shaped gastroduodenostomy (DSG) in totally laparoscopic distal gastrectomy (TLDG) is the presence of intraoperative duodenal injury and postoperative anastomotic stenosis, which can occur due to a relatively short duodenal bulb diameter. MATERIALS AND METHODS: From June 2013 to June 2019, 35 patients with gastric cancer underwent TLDG with a modified DSG consisting of linear stapling and single-layer hand suturing in our institution. All anastomotic procedures were performed by the right hand of the operator positioned between the patient's legs. Linear stapling of the posterior walls of the remnant stomach and duodenum without creating a gap was performed using a 45-mm linear stapler, considering the prevention of intraoperative duodenal injury. The stapler entry hole was closed using a single-layer full-thickness hand suturing technique with knotted sutures and a knotless barbed suture. We described the clinical data and outcomes in the present retrospective patient series. RESULTS: No intraoperative duodenal injury occurred in any of the 35 patients. The median staple length at linear stapling of the posterior walls of the remnant stomach and duodenum was 41.7 ± 4.2 (30-45) mm, and 2 patients (5.7%) had a staple length of 30 mm. There were no incidences of postoperative anastomotic stenosis. CONCLUSIONS: We suggest that a modified DSG consisting of linear stapling and single-layer hand suturing performed by an operator positioned between the patient's legs can be one option for B-Ⅰ reconstruction following TLDG because it can aid in preventing both intraoperative duodenal injury and postoperative anastomotic stenosis.

Pancreaticodudonectomy in trauma: One or two stages?

INTRODUCTION: Duodenopancreatic trauma is rare and presents high morbidity and mortality rates. Pancreaticoduodenectomy (PD) is the only possible treatment indicated for the most complex injuries (grades IV and V). Although, it is commonly a one-stage procedure, damage control surgery corroborates with a two-stage PD performed on unstable trauma victims. OBJECTIVES: Compare the mortality rate of one and two-stage PD in trauma patients. MATERIALS AND METHODS: A systematic electronic search of PubMed, Elsevier, LILACS, Scielo, and Capes was conducted on all studies written in English, Portuguese and Spanish with no restriction to publication dates. Review articles, case reports, editorials, animal studies, pediatric and non-trauma scenarios were excluded. RESULTS: We selected twenty-two publications, with a total of 149 duodenopancreatic trauma victims who underwent PD, with an overall mortality rate of 42 patients (28.2%). Two-stage PD was exclusively performed on unstable patients (N = 31) with a mortality rate of 38.7%. In a sample of 79 patients submitted to a one-stage PD, 38 patients (48.1%) were unstable with a mortality rate of 34.2%. One-stage PD for stable patients had a mortality rate of 14.6% DISCUSSION: Since 1983, hemodynamic state impacts on surgery methods and strategies for trauma patients. Prior to that, one stage PD was not restricted to stable patients. CONCLUSION: There were no differences in mortality rates when comparing two and one-stage PD in hemodynamic unstable patients, who had duodenopancreatic lesions (grades IV or V).

Prognosis of mortality and evolution in pancreatoduodenal trauma in patients with wound by projectile of firearm.

BACKGROUND: The wounds caused by the firearm projectile are published to date in a public health problem in the world. As an example, we mentioned the injuries caused by firearms are the first cause of death in the age group between 1 to 19 years in the United States, as in Mexico. OBJECTIVE: Analysis of the prognostic factors of mortality and evaluation of the evolution in patients with TPD due to abdominal HPPAF. METHOD: Retrospective, observational, descriptive study. Helped by 49 clinical files of patients who were admitted to the department of surgery of the University Hospital José Eleuterio González, between 2011 to 2015 and whose diagnosis was due to pancreatic trauma (TP), duodenal trauma (TD) or pancreatoduodenal trauma (TPD) by wounds caused by the firearm projectile. RESULTS: During a collection period of 5 years, a total of 49 clinical records applicable to the study were obtained according to the inclusion criteria, of which 36 (73%) suffered only from TD, 37 (75%) from TP and 24 (49%) about TPD. Significant differences were obtained for mortality associated with TD and TPD, but not for TP. The most affected organ as a lesion associated with a TPD was the liver, followed by thoracic structures and the stomach. The most significant risk factor for mortality was a prolonged stay in the intensive care unit. CONCLUSIONS: Data obtained are consistent with those consulted, providing new reproducible statistics for future studies regarding the increasing violence in our country and around the world.

ANTECEDENTES: Las heridas por proyectil de arma de fuego constituyen un problema de salud pública en el mundo. Como ejemplo mencionamos que este tipo de lesiones son la primera causa de muerte en el grupo de edad de 1 a 19 años en los EE.UU., al igual que en México. OBJETIVO: Análisis de los factores pronósticos de mortalidad y evaluación de la evolución en pacientes con TPD por HPPAF abdominal. MÉTODO: Estudio retrospectivo, observacional y descriptivo, realizado con 49 expedientes clínicos de pacientes que fueron admitidos en el departamento de cirugía del Hospital Universitario José Eleuterio González entre los años 2011 y 2015, cuyo diagnostico fue herida por proyectil de arma de fuego con trauma pancreático (TP), duodenal (TD) o pancreatoduodenal (TPD). RESULTADOS: Durante un periodo de recolección de 5 años se obtuvieron 49 expedientes clínicos aplicables al estudio según los criterios de inclusión, de los cuales 36 pacientes (73%) sufrieron únicamente TD, 37 (75%) TP y 24 (49%) TPD. Se obtuvieron diferencias significativas para la mortalidad asociada a TD y TPD, pero no para TP. El órgano más afectado como lesión asociada a un TPD fue el hígado, seguido de las estructuras torácicas y el estómago. El factor de riesgo para mortalidad más significativo fue una estancia prolongada en la unidad de cuidados intensivos. CONCLUSIONES: Los datos conseguidos concuerdan con los consultados, otorgando nueva estadística reproducible para futuros estudios respecto a la violencia creciente en nuestro país y alrededor del mundo.

Fully Covered Self-Expandable Metal Stens eliminate surgical repair requirement in both endoscopic sphincterotomy and precut sphincterotomy-related perforation (with video).

OBJECTIVE: Endoscopic retrograde cholangiopancreatography (ERCP)-related perforations occur in 0.3-0.6% of patients. The treatment of retroperitoneal paravaterian perforations (type II), which develop during endoscopic sphincterotomy or precut sphincterotomy, remains a matter of debate. We aimed to evaluate the efficacy of fully covered self expandable metal stent (Fc-SEMS) placement in the treatment of type II perforations. METHODS: The study was conducted in a tertiary ERCP reference center of Turkey between December 2013 and June 2016. Patients with type II ERCP-related perforation constituted the study group. Type II perforations were treated by insertion of an Fc-SEMS (10 mm × 60 mm) during the ERCP procedure or intraoperatively by surgery-endoscopy rendezvous technique, if biliary cannulation could not be achieved. RESULTS: A total of 2689 ERCPs were performed. ERCP-related perforation was observed in 12 procedures (0.4%). Eight patients had Stapfer type II perforations, which developed during endoscopic sphincterotomy in seven patients and precut sphincterotomy in one patient. Fc-SEMSs were inserted during the ERCP procedure in seven patients and intraoperatively by surgery-endoscopy rendezvous technique in one patient. None of the patients developed fever, hemodynamic instability, or peritoneal signs. Stents were removed after a median duration of 9 (3-14) days. All of the patients were uneventfully discharged after an average hospital length of stay of median 5 (1-9) days. CONCLUSION: Fc-SEMSs are highly effective in the nonoperative treatment of type II perforations and their intraoperative insertion in patients with unsuccessful cannulation may facilitate surgery by eliminating the need for duodenum repair surgery.
