A systematic review of penetrating perineal trauma in a civilian setting

PURPOSE

Penetrating injuries to the perineum and associated pelvic organs have largely been reported in the military. Given the rarity of presentation and unique clinical characteristics of these injuries, we set out to address the gap in the literature in civilian settings.

METHODS

A systematic review of studies addressing penetrating perineal trauma from January 2000 to April 2021 was performed. Outcomes of interest were the epidemiology, associated injuries, management, follow-up, and patient outcomes.

RESULTS

26 studies were included in this review, reporting on a total of 2316 patients. Most injuries occurred in males (88.1%), with gunshot wounds (88.2%) representing the most common aetiology, followed by knife wounds (5.0%), impalement (3.1%), coital injuries/sexual assault (1.5%), and others (2.4%). Regarding associated injuries, anorectal (n = 1419, 69.4%), bladder (n = 351, 32.4%), penile (n = 282, 20.8%), scrotal (n = 375, 27.7%), and testicular (n = 229, 16.9%) occurred frequently. Bony injuries involved the pelvis (n = 88, 8.1%) and femoral fractures (n = 5, 0.5%), while soft-tissue injuries involved the inguinal region (n = 19, 1.6%) and buttocks (n = 14, 1.3%). Vascular injuries occurred in 79 (7.8%) patients. Regarding patient outcomes, 65 (4.8%) deaths were reported, and significant morbidity was detected with a mean injury severity score of 18.4 detected in the cohort. In terms of complications of injury, wound/infective complications (n = 135, 61.3%) and fistula formation/leakage (n = 16, 0.7%) featured prominently.

CONCLUSION

Penetrating perineal trauma in the civilian population poses a considerable challenge to clinicians, compounded by the potential for multisystem injury requiring involvement of different medical and surgical specialties.

WSES guidelines on blunt and penetrating bowel injury: diagnosis, investigations, and treatment

The aim of this paper was to review the recent literature to create recommendations for the day-to-day diagnosis and surgical management of small bowel and colon injuries. Where knowledge gaps were identified, expert consensus was pursued during the 8th International Congress of the World Society of Emergency Surgery Annual (September 2021, Edinburgh). This process also aimed to guide future research.

Minimally invasive approach to low-velocity penetrating extraperitoneal rectal trauma

Unlike intraperitoneal colorectal injuries, the standard of care for extraperitoneal rectal trauma includes a diverting colostomy due to relative inaccessibility of these injuries for primary repair. New technologies to enhance access to the extraperitoneal rectum have gained increasing use in benign and malignant rectal disease. We present two cases of low-velocity penetrating extraperitoneal rectal trauma. In both cases, a transanal minimally invasive surgery (TAMIS) approach was used to access, and primarily repair, full-thickness rectal lacerations. These patients were successfully managed without a colostomy and without complication. TAMIS enables access to distal rectal injuries, facilitating primary repair and bringing the management of extraperitoneal rectal injuries in line with intraperitoneal injuries, with the potential to avoid fecal diversion.

Rectal Trauma: Evidence-Based Practices

The management of rectal trauma has often been lumped in with colon trauma when, in fact, it is a unique entity. The anatomic nature of the rectum (with its intra- and extraperitoneal segments) lends itself to unique circumstances when it comes to management and treatment. From the four Ds (debridement, drainage, diversion, and distal irrigation), the management of rectal trauma has made some strides in light of the experiences coming out of the recent conflicts overseas as well as some rethinking of dogma. This article will serve to review the anatomy and types of injuries associated with rectal trauma. A treatment algorithm will also be presented based on our current literature review. We will also address controversial points and attempt to give our opinion in an effort to provide an update on an age-old problem.

Management of penetrating extraperitoneal rectal injuries: An Eastern Association for the Surgery of Trauma practice management guideline

BACKGROUND

The management of penetrating rectal trauma invokes a complex decision tree that advocates the principles of proximal diversion (diversion) of the fecal stream, irrigation of stool from the distal rectum, and presacral drainage based on data from World War II and the Vietnam War. This guideline seeks to define the initial operative management principles for nondestructive extraperitoneal rectal injuries.

METHODS

A systematic review of the MEDLINE database using PubMed was performed. The search retrieved English language articles regarding penetrating rectal trauma from January 1900 to July 2014. Letters to the editor, case reports, book chapters, and review articles were excluded. Topics of investigation included the management principles of diversion, irrigation of stool from the distal rectum, and presacral drainage using the GRADE methodology.

RESULTS

A total of 306 articles were screened leading to a full-text review of 56 articles. Eighteen articles were used to formulate the recommendations of this guideline.

CONCLUSION

This guideline consists of three conditional evidence-based recommendations. First, we conditionally recommend proximal diversion for management of these injuries. Second, we conditionally recommend the avoidance of routine presacral drains and distal rectal washout in the management of these injuries.

Fecal continence following complex anorectal trauma in children

BACKGROUND

Complex injuries involving the anus and rectum are uncommon in children. We sought to examine long-term fecal continence following repair of these injuries.

METHODS

We conducted a retrospective review using our trauma registry from 2003 to 2012 of children with traumatic injuries to the anus or rectum at a level I pediatric trauma center. Patients with an injury requiring surgical repair that involved the anal sphincters and/or rectum were selected for a detailed review.

RESULTS

Twenty-one patients (21/13,149 activations, 0.2%) who had an injury to the anus (n=9), rectum (n=8), or destructive injury to both the anus and rectum (n=4) were identified. Eleven (52%) patients were male, and the median age at time of injury was 9 (range 1-14) years. Penetrating trauma accounted for 48% of injuries. Three (14%) patients had accompanying injury to the urinary tract, and 6 (60%) females had vaginal injuries. All patients with an injury involving the rectum and destructive anal injuries were managed with fecal diversion. No patient with an isolated anal injury underwent fecal diversion. Four (19%) patients developed wound infections. The majority (90%) of patients were continent at last follow-up. One patient who sustained a gunshot injury to the pelvis with sacral nerve involvement is incontinent, but remains artificially clean on an intense bowel management program with enemas, and one patient with a destructive crush injury still has a colostomy.

CONCLUSIONS

With anatomic reconstruction of the anal sphincter mechanism, most patients with traumatic anorectal injuries will experience long-term fecal continence. Follow-up is needed as occasionally these patients, specifically those with nerve or crush injury, may require a formal bowel management program.

Penetrating bladder trauma: a high risk factor for associated rectal injury

Demographics and mechanisms were analyzed in prospectively maintained level one trauma center database 1990-2012. Among 2,693 trauma laparotomies, 113 (4.1%) presented bladder lesions; 51.3% with penetrating injuries (n = 58); 41.3% (n = 24) with rectal injuries, males corresponding to 95.8%, mean age 29.8 years; 79.1% with gunshot wounds and 20.9% with impalement; 91.6% arriving the emergence room awake (Glasgow 14-15), hemodynamically stable (average systolic blood pressure 119.5 mmHg); 95.8% with macroscopic hematuria; and 100% with penetrating stigmata. Physical exam was not sensitive for rectal injuries, showing only 25% positivity in patients. While 60% of intraperitoneal bladder injuries were surgically repaired, extraperitoneal ones were mainly repaired using Foley catheter alone (87.6%). Rectal injuries, intraperitoneal in 66.6% of the cases and AAST-OIS grade II in 45.8%, were treated with primary suture plus protective colostomy; 8.3% were sigmoid injuries, and 70.8% of all injuries had a minimum stool spillage. Mean injury severity score was 19; mean length of stay 10 days; 20% of complications with no death. Concomitant rectal injuries were not a determinant prognosis factor. Penetrating bladder injuries are highly associated with rectal injuries (41.3%). Heme-negative rectal examination should not preclude proctoscopy and eventually rectal surgical exploration (only 25% sensitivity).

Rectum perforation after broomstick impalement in a 17-year-old: case report and review

Impalement injuries are uncommon, especially in the pediatric population. Because of the rarity of these injuries, physicians may have difficulty recognizing and treating impalement injuries appropriately. Clinical findings are sometimes innocuous, but can be life threatening. Therefore, evaluation of suspected impalement injury should involve careful history and thorough physical examination, even if there is no evidence of trauma to the perineum. We report a very rare case of rectum perforation after transanal introduction of a broomstick with almost no clinical findings. Impalement injuries are difficult to recognize, and severity may not be reflected by their external appearance. To diagnose these injuries in time, it is important to use a well-organized workup.

Rectal trauma in adults

Rectal trauma is associated with high rates of morbidity and mortality and generally affects young males due to its aetiology of violent crime and vehicular collision. Historically, management has followed principles derived from military practice, with faecal diversion, pre-sacral drainage and distal washout being mandatory. Civilian trauma studies examining management of colon and rectum injuries from the early 1950s identified major differences in the level of energy transfer between civilian and military wounds, given that the vast majority are penetrating in nature. This led to a re-evaluation of the necessity for these interventions for all rectal injuries. Current management depends on whether the injury is intra- or extraperitoneal, with those above the peritoneal reflection being readily accessible and amenable to treatment as for colon injury. Extraperitoneal injuries remain difficult to access and direct repair is usually impossible; the mainstay of treatment in most instances remains faecal diversion. The role of pre-sacral drainage and distal washout remains contentious in the realms of civilian rectal injury but retains a place in battlefield or other high-energy transfer rectal injuries where aggressive early management reduces septic complications. This article reviews the historical and current evidence for the management of both civilian and military extraperitoneal rectal injuries.

Current management of severe pelvic and perineal trauma

Mortality associated with pelvic and perineal trauma (PPT) has fallen from 25% to 10% in the last decade thanks to progress accomplished in medical, surgical and interventional radiology domains (Dyer and Vrahas, 2006) [1]. The management strategy depends on the hemodynamic status of the patient (stable, unstable or extremely unstable). Open trauma requires specific treatment in addition to control of bleeding. All surgical centers can be confronted some day with patients with hemorrhagic PPT and for this reason, all surgeons should be familiar with the initial management. In expert centers, management of patients with severe PPT is complex, multidisciplinary and often requires several re-interventions. Obstetrical and sexual trauma, also requiring specific management, will not be dealt with herein.

Traumatic injury of the colon and rectum: the evidence vs dogma

BACKGROUND

The treatment of traumatic injuries to the colon and rectum is often driven by dogma, despite the presence of evidence suggesting alternative methods of care.

OBJECTIVE

This is an evidence-based review, in the format of a review article, to determine the ideal treatment of noniatrogenic traumatic injuries to the colon and rectum to improve the care provided to this group of patients. Recommendations and treatment algorithms were based on consensus conclusions of the data.

DATA SOURCES

A search of MEDLINE, PubMed, and the Cochrane Database of Collected Reviews was performed from 1965 through December 2010.

STUDY SELECTION

Authors independently reviewed selected abstracts to determine their scientific merit and relevance based on key-word combinations regarding colorectal trauma. A directed search of the embedded references from the primary articles was also performed in select circumstances. We then performed a complete evaluation of 108 articles and 3 additional abstracts.

MAIN OUTCOME MEASURES

The main outcomes were morbidity, mortality, and colostomy rates.

RESULTS

Evidence-based recommendations and algorithms are presented for the management of traumatic colorectal injuries.

LIMITATIONS

Level I and II evidence was limited.

CONCLUSIONS

Colorectal injuries remain a challenging clinical entity associated with significant morbidity. Familiarity with the different methods to approach and manage these injuries, including "damage control" tactics when necessary, will allow surgeons to minimize unnecessary complications and mortality.

Anorectal trauma: the use of computed tomography scan in diagnosis

Anorectal injuries represent a relatively uncommon but clinically critical diagnosis in trauma. Anorectal injuries may be the result of penetrating injuries to the pelvis and perineal area as well as severe blunt traumatic injuries, often with pelvic fractures. The purpose of this review is to discuss injuries to the anorectal region sustained in trauma, specifically, in the application of multidetector computed tomography technology to these imaging diagnoses. An understanding of the pertinent anatomy is critical in characterization of these injuries using computed tomography (CT). Additionally, the subsequent clinical management decisions and how they are impacted by severity and location of injury in anorectal trauma is useful to the radiologist. This should serve to highlight the specific areas and injury distinctions that deserve our particular attention given possible changes in the ensuing management approaches. CT protocol issues including the use of oral, rectal, and intravenous contrast, as necessary, are relevant in maximizing the diagnostic accuracies of CT in anorectal trauma. This review serves to discuss and illustrate these pertinent issues, approaching penetrating and blunt trauma separately, with the emphasis on multidetector computed tomography in diagnosis.

Civilian Extraperitoneal Rectal Gunshot Wounds: Surgical Management Made Simpler

BACKGROUND

Rectal injuries are associated with significant morbidity and mortality. Controversy persists regarding routine presacral drainage, distal rectal washout (DRW), and primary repair of extraperitoneal rectal injuries. This retrospective review was performed to determine the outcome of rectal injuries in an urban trauma center with a high incidence of penetrating trauma where a non-aggressive surgical approach to these injuries is practiced.

METHODS

The records of all patients with a full-thickness penetrating rectal injury admitted to the Trauma Center at Groote Schuur Hospital over a 4-year period were reviewed. These were reviewed for demographics, injury mechanism and perioperative management, anatomical site of the rectal injury, associated intra-abdominal injuries and their management. Infectious complications and mortality were noted. Intraperitoneal rectal injuries were primarily repaired, with or without fecal diversion. Extraperitoneal rectal injuries were generally left untouched and a diverting colostomy was done. Presacral drainage and DRW were not routinely performed.

RESULTS

Ninety-two patients with 118 rectal injuries [intraperitoneal (7), extraperitoneal (59), combined (26)] were identified. Only two extraperitoneal rectal injuries were repaired. None had presacral drainage. Eighty-six sigmoid loop colostomies were done. Two (2.2%) fistula, one rectocutaneous, and one rectovesical, were recorded. There were nine (9.9%) infectious complications: surgical site infection (4), buttock abscess (1), buttock necrosis (1), pubic ramus osteitis (1), septic arthritis (2). No perirectal sepsis occurred.

CONCLUSIONS

Extraperitoneal rectal injuries due to low-velocity trauma can be safely managed by fecal diversion alone.

When Trauma Means a Stoma

Trauma is a leading cause of death and disability. When traumatic injuries require ostomy surgery, the wound, ostomy, and continence nurse acts as a crucial part of the trauma team. This literature review describes mechanisms of injury associated with creation of a stoma, key aspects of wound, ostomy, and continence nursing care in trauma populations and presents suggestions for future research.

[Current situation of colorectal trauma]

Mortality from colorectal trauma decreased from the end of the 19th Century, when death was the rule, to the 21st Century, when mortality is 5%. The greatest advances were produced during wars, mainly due to improved transport conditions, antisepsis, advances in operating and anesthetic techniques, the management of fluids, blood and blood products, the use of antibiotics, exteriorization of wounds, and the use of colostomy. Injuries to the anus, rectum and colon are infrequent. Their prevalence is difficult to establish because they can be caused by several factors. In Spain, the most frequent causes are traffic accidents and iatrogenic lesions, while in America the most common causes are stab or gunshot wounds. Although the etiology of these injuries is diverse, two major groups of colorectal trauma can be established: accidental injuries and iatrogenic trauma. Clinical symptoms vary, ranging from abdominal, pelvic, perianal or anal pain, sometimes associated with rectorrhagia, to peritonismus or shock. Diagnosis is based on physical and rectal examination and laboratory, radiological, and endoscopic investigations. Laparoscopy can also be used on occasions. Treatment should be individualized, depending on the patient's history, current status, the time elapsed since injury, the status of the injured intestine, the degree of fecal contamination, associated lesions, and the surgeon's experience.

Perspectives on Surgery in the New South Africa

Radical changes have occurred in the health care system since the democratization of South Africa in 1994, with the emphasis on improving previously neglected community-based primary health care. Because of the resultant financial constraints, funding of tertiary academic centers has been drastically cut which has compromised their proud record of service, teaching, and research excellence. Tertiary surgery has been particularly affected and now lags in the acquisition of new technologies which form an integral part of teaching and modern day practice. The acute shortage of full-time surgeons in regional public hospitals has prompted the government to fill vacancies with surgeons from foreign countries. In stark contrast, an abundance of surgeons in the relatively small private sector enjoy the benefits of the very best of First World medicine. The ultimate goal is a seamless progression of effective health care at all levels. It behooves the main role players to ensure that the high standard of training of South African doctors, which has international recognition, is maintained during this transition period.
