Surgical management of colorectal injury in war.

The rate of colorectal trauma is 5-10 % in modern war conflicts. The most common causes include gunshots or shrapnel injuries; the contusion-laceration mechanism occurs in sporadic cases in the war zone. Despite modern surgical procedures, however, it is associated with a high rate of morbidity, especially if it is not diagnosed and treated in time. Surgical management is specified by simple scoring schemes - the colon injury scale, rectal injury scale and the Flint grading system. Colonic resection with primary or delayed anastomosis is not associated with a higher risk of complicated healing and is nowadays preferred over the construction of terminal stomas. These are indicated only for cases with severe hemodynamic instability in traumatic-hemorrhagic or septic shock with severe diffuse peritonitis. Trauma to the intraperitoneal segment of the rectum is treated in the same way as trauma to the colon. An extraperitoneal rectal injury without soft tissue devastation can be treated with or without a transanal suture. On the contrary, devastating injuries to the rectum including the pelvic soft tissues should be primarily controlled with a stoma with delayed reconstruction. Presacral drainage or rectal stump lavage are no longer recommended.

Role of hydrogen peroxide injection for penetrating abdominal injury in creating CT Tractogram.

Penetrating abdominal trauma is responsible for approximately 35% of patients admitted to urban trauma centers, and up to 12% of those admitted in suburban or rural centers in the United States. Current protocol relies heavily on CT imaging as the diagnostic tool in evaluating for peritoneal violation in hemodynamically stable patients, however it is associated with false negative rates. In addition, visualization of the fascia of the rectus abdominis, the transversalis fascia, and the peritoneum cannot be reliably identified with CT. Studies have probed into the use of injecting IV contrast dyes prior to imaging to establish a CT tractography. We present a case of a 31-year-old male presenting to the emergency department for evaluation of stab wounds following an altercation. On exam, a 1 cm penetrating wound to the LUQ of his abdomen was noted. A CT scan of the abdomen and pelvis was performed with 91 mL of Omnipaque-350 intravenous contrast. Prior to imaging, 30 mL of hydrogen peroxide was injected directly into the opening site of the stab wound to amplify the wound tract. The result was a well-visualized intact peritoneum. We propose hydrogen peroxide as an alternative method to liquid contrast in reestablishing the stab wound tract. This method creates a negative contrast level to augment the ability of CT imaging to determine peritoneal penetration. Key Words: Penetrating Abdominal Injury, CT Tractography, Abdominal Trauma, Hydrogen Peroxide, Trauma Management.

A clinical observation algorithm for anterior abdominal stab wound is safe in an Australian setting.

INTRODUCTION: We previously published the outcomes associated with the use of diagnostic laparoscopy to determine peritoneal breach for AASW patients without an immediate indication for laparotomy. Although this pathway was 100% sensitive there was a 54% non-therapeutic laparotomy rate. Another option that has been extensively reported is the clinical observation algorithm (COA) however, majority of the data originate from high-volume centres. We hypothesized that a COA would also be a safe option in an Australian setting, and reduce the rate of non-therapeutic operative intervention in managing AASW. METHODS: This was a prospective cohort study examining patients with AASW admitted to a level 1 trauma centre in Sydney, Australia, between June 2021 and August 2023. Patient, injury, management and outcome data were collected from electronic medical records and the hospital trauma registry. Data were then analysed to determine the diagnostic accuracy of the COA, complication rates and median hospital length-of-stay (LOS). RESULTS: A total of 48 patients presented with AASW. Of these patients, 11 (22.9%) proceeded to immediate laparotomy. Seven patients had a contraindication to COA and underwent diagnostic laparoscopy. Thirty patients were managed with the COA, with three (10%) patients subsequently requiring a laparotomy. Only one patient (3.3%) underwent a non-therapeutic laparotomy. There were no missed injuries. The COA sensitivity was 100%, specificity 92.7%, PPV 50% and NPV 100%. Patients managed with COA had no complications. Overall median hospital LOS was 1 day (1.0-2.3). CONCLUSION: A COA is a safe approach for evaluating patients with AASW in an Australian setting with adequate resources. It reduces the rate of non-therapeutic operative intervention and has acceptable outcomes compared with a diagnostic laparoscopy pathway.

Prevalence, Pattern, Mortality, and Morbidity of Traumatic Small Bowel Perforation at King Abdulaziz Medical City: A Retrospective Cohort Study.

Introduction Bowel perforation, whether from trauma or other causes, presents with diverse clinical scenarios. Small bowel perforation (SBP), a potentially fatal condition often linked to blunt trauma like motor vehicle accidents, necessitates prompt detection and intervention, crucial for improved outcomes. This study investigated the prevalence, predictors, presentation, diagnostic findings, morbidity, and mortality of traumatic SBP for comprehensive insights. Methodology This was a retrospective cohort study conducted at King Abdulaziz Medical City, Riyadh. A review of 838 cases, which represent all abdominal trauma patients from January 2017 to March 2023, was done. Forty patients who developed SBP and have complete data were included in this study. One case was excluded due to incomplete medical records. Data were collected with the non-probability convenience sampling technique via the BestCare system using a data collection sheet. Data were analyzed with IBM SPSS 29 (IBM Corp., Armonk, NY). Results Out of all abdominal trauma cases (n=838), 40 patients developed SBP (n=40, 4.77%). Males constituted 87.5%, and the most common mechanism was motor vehicle accidents (57.5%). Complications included cardiac arrest, disseminated intravascular coagulation (DIC), and leak (7.5% each). In motor vehicle accidents, SBP primarily affected patients who were in the driver's position (78.3%). Clinical signs at presentation revealed abdominal tenderness (52.5%), abdominal distension (22.5%), and abnormal systolic blood pressure (mean 115.3 mmHg). Linear regression showed gender and age positively associated with morbidity (p=0.474, p=0.543) while BMI exhibited a negative relationship (p=0.314). Logistic regression revealed non-significant predictors of mortality, except for mean initial hematocrit (HCT) (p=0.721, aOR=0.098). Conclusion Our study provides crucial findings on the incidence, patterns, mortality, and morbidity of traumatic bowel perforation, contributing to the existing body of research. The identified prevalence of 4.77% and mortality at 17.5% from the studied population underline the serious impact of this condition, and the 37.5% complication rate observed demonstrates the potential risks involved. The average hospital stay is found to be 14 days, adding further to the disease burden. These findings underscore the importance of specific preventative measures, particularly related to motor vehicle accidents (MVAs), and highlight potential markers for predicting outcomes, such as age, gender, and mean initial HCT. This substantiates the need for further research involving larger cohorts and prospective designs to gain comprehensive insights and establish more robust preventative and treatment strategies.

Chyloperitoneum After Penetrating Abdominal Trauma: A Report of a Rare Case.

The term chyloperitoneum refers to the accumulation of triglyceride-rich fluid in the peritoneal cavity. It is an uncommon clinical condition that usually occurs due to disruption of lymphatic flow secondary to trauma or obstruction. Common causes include penetrating or blunt trauma, iatrogenic injuries, congenital anomalies, malignant neoplasms, infections such as tuberculosis and filariasis, liver cirrhosis, constrictive pericarditis, congestive heart failure, inflammatory conditions, such as sarcoidosis and pancreatitis, and radiation- and drug-related pathologies. We present a case of chyloperitoneum in a 33-year-old woman secondary to penetrating abdominal trauma secondary to a gunshot wound. The patient was successfully managed with total parenteral nutrition and octreotide administration. To our knowledge, this is the only case of chylous ascites caused by a penetrating injury that has been reported in the literature. Conservative management with the initiation of total parenteral nutrition and octreotide led to the resolution of this condition.

Management of a Transaxial, Tricompartmental Gunshot Injury in a Low-Resource Tertiary-Care Center in the Anglosphere Caribbean.

Trauma, both penetrating and blunt, consists of a significant percentage of surgical admissions in Caribbean hospitals. Due to financial constraints, ideal resources for optimal surgical management are not always available. Despite these disadvantages, successful outcomes for complex, emergent cases are achieved through a combination of timely clinical assessment, intervention, and ingenuity in using the resources at hand. In this case report, we describe a 17-year-old male who suffered major visceral injuries and presented in extremis from a single gunshot wound. While fleeing the scene of a crime, he was shot in his right pelvis, with the projectile exiting his left thorax. Injuries matching a transaxial gunshot trajectory that crossed the diaphragm and involved the pelvic, abdominal, and thoracic cavities were found on exploratory laparotomy. He survived through prompt surgical intervention and aggressive resuscitation during his postoperative intensivist care, a resource often unavailable in this setting. The patient's prognosis would have been guarded even in a developed country setting. This case highlights the potential that Caribbean healthcare institutes possess, and that given an improvement in resources, we can aim to match a developed country's standard of healthcare.

Treatment outcomes of penetrating abdominal injury requiring laparotomy at Hiwot Fana Specialized University Hospital, Harar, Ethiopia.

Background: Penetrating abdominal injury (PAI) is a public health problem and accounts for significant mortality and disability in both developing and developed countries. It often causes damage to internal organs, resulting in shock and infection. In this study, we assessed the outcomes of PAI and factors associated with post-surgical outcomes including surgical site infection (SSI) and in-hospital death. Methods: An institution-based cross-sectional study was conducted from 15 January to January 30, 2020, using a standard checklist to review the clinical charts of patients who presented to Hiwot Fana Specialized University Hospital (HFSUH) with PAI and underwent laparotomy between January 2015 and September 2019. Descriptive statistics were used to describe the characteristics of patients, and odds ratios (ORs) with a 95% confidence interval (CI) were reported for factors included in binary logistic regression. The statistical significance was declared at a P-value <0.05. Results: A total of 352 charts of patients with PAI were reviewed. A majority of them (84.9%) were males and the mean age was 26.5 years. The anterior abdomen was the most common site of injury, accounting for 285 patients (81%), 329 patients (93.5%) suffered organ injury, 204 (62%) had a single organ injury, and 125 (38%) had more than one organ injury. The leading injured organs were small intestines 194 (55.1%), followed by the colon 88 (25%) and liver 40 (11.4%). The magnitude of SSI and hospital death was 84 (23.9%) and 12 (3.4%), respectively. Patients above 45 years of age (AOR = 2.9, 95% CI: 1.2, 9.2), with fluid collection (AOR = 2.7, 95% CI: 1.2, 5.9), colostomy (AOR = 3.9, 95% CI: 1.9, 7.8), body temperature >37.5 °C (AOR = 3.8,95% CI:1.9,7.6), and Hgb < 10 mg/dl (AOR = 7.4, 95% CI: 3.4,16.1) had a higher likelihood of SSI. Those patients admitted to the intensive care unit (AOR = 21.3, 95% CI: 1.1, 412.3) and who underwent damage control surgery (AOR = 9.6, 95% CI: 1.3, 73.3) had a higher likelihood of mortality. Conclusions: SSI and death among patients with PAI were high. Age, fluid collection, colostomy, body temperature, and hemoglobin level were statistically associated with SSI, and intensive care unit and damage control surgery were statistically associated with death. Therefore, health professionals working in surgical wards should consider these factors to alleviate SSI and prevent death. Broadly speaking, the guidelines of the World Society of Emergency Surgery (WSES) should consider these factors in their recommendations.

Rare penetrating abdominal injury caused by falling from height: Miraculously good prognosis.

Fall from height causing penetrating abdominal visceral injuries is rare condition leading to abdominal multiorgan damage. It carries high mortality. A case of construction site worker sustaining penetrating visceral injuries by falling from height leading to impalement of steal bar from anus presented to our hospital and managed by timely evacuation from site of accident to hospital, resuscitations, radiological investigations and multi-Disciplinary team management lead to successful outcome. Our protocol for such cases will be discussed with references.

High-Velocity Penetrating Abdominal Injury Secondary to a Motorized Wire Brush in the Workplace.

Penetrating injuries are one of the most common types of workplace accidents. The majority of these injury patterns are due to non-missile type, low-velocity sharp objects. We present an uncommon presentation of subacute abdominal pain secondary to non-missile type, high-velocity workplace injury. It is important to keep a wide differential in mind when evaluating patients with lingering abdominal pain without an obvious cause. Additionally, collecting the patient's employment history, occupational exposures, and job tasks are important when a workplace injury is suspected. We present the case of a 59-year-old male with abdominal pain for five weeks. Outpatient CT scan of the abdomen/pelvis demonstrated a metallic foreign body within the abdominal cavity. The patient underwent laparoscopic removal of the intra-abdominal foreign body while utilizing fluoroscopy. He recovered without sequelae and he was free of abdominal pain at six months postoperatively. Overall, it is important to maintain a wide differential when evaluating atypical abdominal pain.

A study on initial outcome of selective non-operative management in penetrating abdominal injury in a tertiary care hospital in Bangladesh.

OBJECTIVES: The aim of this study was to assess the initial outcome of non-operative, conservative management in selective penetrating abdominal injury in a tertiary care hospital. MATERIAL AND METHODS: This was a cross sectional study done on purposively selected 36 patients with penetrating abdominal injuries of all ages admitted within 6 hours of the incident. All patients confirmed peritoneal breach and standard algorithm of management was followed. Closed monitoring was ensured with repeated investigations at regular intervals. Outcome parameters included surgical site infection (SSI), fever, hypothermia, wound dehiscence, fecal fistula, length of stay, pulmonary complication and death. RESULTS: A total of 36 patients with a mean age of 30 years (SD= 6.7), consisting all males, mostly (58%) from rural areas and 73% from low socioeconomic condition. Site of injury was noted in the epigastrium (42%) and right iliac region (22%). Among them, 33 (92%) patients were successfully managed with non-operative management and 3 (8%) patients needed laparotomy. Routine imaging and clinical observation could detect hollow viscus injury within 36 hours in 3 patients. Hospital stay was significantly lower ( <7 days) in conservative management. CONCLUSION: Clinical examination alone and/or together with different diagnostic methods could reduce the number of negative laparotomies and associated morbidities. Single surgeon must closely monitor a patient of penetrating abdominal injury and take vital decisions from the time of admission until discharge.

Endoluminal closure of an unrecognized penetrating stab wound of the duodenum with endoscopic band ligation: A case report.

BACKGROUND: A penetrating injury of a hollow viscus is an obvious indication for an exploratory laparotomy, but is not typically an indication for endoscopic treatment. CASE SUMMARY: A 27-year-old man visited the emergency department with a self-inflicted abdominal stab wound. Injuries to the colon and ileum were detected, but an injury to the second portion of the duodenum was missed. On the day following admission to our institution, the patient became hemodynamically unstable with massive hematochezia, although there was no evidence of bleeding in the Levin tube or Jackson-Pratt drain. We thus performed an upper gastrointestinal endoscopy and discovered a missed duodenal injury that was actively bleeding. An endoscopic band ligation was performed for hemostasis and closure of the perforation. The patient was subsequently discharged without any complications. CONCLUSION: A penetrating injury of the duodenum can be overlooked, so careful abdominal exploration is very important. If a missed duodenal injury is suspected, a cautious endoscopic approach may be helpful.

Multidetector Computed Tomography Imaging of Damage Control Surgery Patients.

Damage control surgery is a staged surgical procedure in a patient who has suffered penetrating or blunt abdominal traumatic injury with severe metabolic derangements. Multidetector computed tomography scanning is a vital tool for patient management in the damage control patient, providing many uses, including assessing the extent of traumatic injury, evaluating areas that were not surgically explored, evaluating for injuries that were missed during the initial surgery, and assessing the stability of surgical repair. Understanding the postsurgical multidetector computed tomography appearance of these patients can aid the radiologist in protocol optimization and provide immediate accurate diagnoses.

Review of Pancreaticoduodenal Trauma with a Case Report.

Complex anatomical relation of the duodenum, pancreas, biliary tract, and major vessels plays to obscure pancreaticoduodenal injuries. Causes of pancreaticoduodenal injuries are blunt trauma (traffic accidents, sport injuries) in 25 % of cases and penetrating abdominal injuries (stab wounds and firearm injuries) in 75 % of cases. Duodenal injuries are reported to occur in 0.5 to 5 % of all abdominal trauma cases and are observed in 11 % of abdominal firearm wounds, 1.6 % of abdominal stab wounds, and 6 % of blunt trauma. Retroperitoneal and deep abdominal localization of duodenum as an organ contribute to the difficulty in diagnosis and treatment. There are three important major points regarding treatment of duodenal injuries: (1) operation timing and decision, (2) Intraoperative detection, and (3) post-operative care. Therefore, it is difficult to diagnose and treat duodenal trauma. We would like to present a 21-year-old male patient with pancreaticoduodenal injury who presented to our emergency service after firearm injury to his abdomen and discuss his treatment with a short review of related literature.

[Penetrating abdominal wounds caused by weapons in the service of general surgery in the Gabriel Touré teaching hospital]. / Plaies penetrantes abdominales par armes dans le service de chirurgie generale du CHU Gabriel Toure.

INTRODUCTION: Providing care for penetrating abdominal wounds is a controversial subject. The aim of this project was to describe their epidemiological, clinical and therapeutic aspects. MATERIALS AND METHODS: This retrospective study conducted over 4 years, from January 2006 to January 2010 concerned 70 cases of penetrating abdominal injury in the general surgery department of the Gabriel TOURE teaching hospital. Non-piercing and animal horn related abdominal injuries were not included. RESULTS: We collated 70 cases of penetrating abdominal wounds; representing 1.2% of hospitalisations during the studied time frame. The patients were 12 to 59 years old with a mean age of 27.7 years and a sex-ratio of 9 to 1 for men. 27 patients (38.36%) came from districts I and II of Bamako. Criminal injuries was the main cause of injury encountered representing 70% cases. 3 of the patients had psychiatric antecedents and 45.7% of patients regularly consumed drugs. The epiploon and small intestine were the main eviscerated organs (51.4% cases). 17/53 patients received non-surgical treatment. The rate of laparotomia was of 30.2% and postoperative morbidity 15.1%. CONCLUSION: Treating penetrating abdominal injury remains difficult. A good selection of patients allow the service to lower the rate of laparotomia.

INTRODUCTION: La prise en charge des plaies pénétrantes de l'abdomen est encore sujet à controverses. Les objectifs de ce travail étaient d'étudier les aspects épidémiologiques, cliniques et thérapeutiques. MATÉRIELS ET MÉTHODE: Cette étude rétrospective de 4 ans, de janvier 2006 à janvier 2010 portant sur 70 cas de plaies pénétrantes de l'abdomen, a été réalisée dans le service de chirurgie générale du CHU Gabriel Touré. Les plaies non pénétrantes et les encornements ont été non inclus. RÉSULTATS: A l'issue de l'étude, nous avons colligé 70 cas de plaies pénétrantes abdominales;ce qui a représenté 1,2% des hospitalisations. L'âge moyen des patients a été de 27,7 ans(extrêmes 12 et 59 ans) avec un sex ratio de 9 pour les hommes. Vingt sept patients (38,36%) viennent de la commune I et II. L'agression criminelle a été la circonstance de survenue la plus fréquente (70%). Trois de nos patients avaient un antécédent psychiatrique et 45,7% consommaient des stupéfiants. L'épiploon et le grêle ont été les organes les plus éviscérés (51,4%).Dix sept patients sur 53 ont bénéficié du traitement non opératoire. Notre taux de laparotomie blanche a été de 30,2% et la morbidité post opératoire était de 15,1%. CONCLUSION: La gestion des plaies pénétrantes abdominales reste difficile. Une bonne sélection des patients permet de diminuer le taux de laparotomie blanche.

Penetrating abdominal injury in a polytrauma patient: Anaesthetic challenges faced.

Penetrating abdominal injuries are potentially life threatening due to the associated hemorrhagic shock and visceral injury. Through and through penetrating injury with polytrauma is rarely encountered. We report a case presenting with in situ projecting heavy metallic rod in a through and through penetrating abdominal injury along with foreign body in a road traffic accident. Anaesthetic management was difficult due to inability to position in supine, rapidly progressing hemorrhagic shock and hypoxia due hemopneumothorax. Two operating tables were used with adequate intervening space to accommodate the posteriorly projecting metallic rod during intubation in supine position. Intensive monitoring and resuscitation resulted in uneventful successful outcome.
