Gastrointestinal surgery and related complications in patients with Ehlers-Danlos syndrome: a systematic review

Small bowel perforation caused by a fish bone in a patient with vascular Ehlers-Danlos syndrome: a case report

Management of gastrointestinal perforation in patients with vascular Ehlers-Danlos syndrome (vEDS) is clinically challenging. A male in his 40s with vEDS presented with right lower abdominal pain. Computed tomography revealed a foreign body in the ileum with bowel perforation. A detailed inquiry revealed that he had consumed codfish six days prior. Based on these findings, he was diagnosed with a small bowel perforation caused by a fish bone. Emergency laparotomy was performed and intraoperative findings showed a fish bone in the ileum penetrating the mesentery. We resected ~5 cm of the small intestine, including the perforation site. Although the patient experienced postoperative paralytic ileus, he was discharged on postoperative Day 27. Gastrointestinal perforation caused by fish bones in patients with vEDS is extremely rare and requires careful assessment to determine the appropriate treatment. For surgeons, an individualized surgical strategy and optimal perioperative management are important to prevent fatal complications.

Neuraxial biomechanics, fluid dynamics, and myodural regulation: rethinking management of hypermobility and CNS disorders

Individuals with joint hypermobility and the Ehlers-Danlos Syndromes (EDS) are disproportionately affected by neuraxial dysfunction and Central Nervous System (CNS) disorders: such as Spontaneous Intracranial Hypotension (SIH) due to spinal cerebrospinal fluid (CSF) leaks, Upper Cervical Instability (UCI; including craniocervical or atlantoaxial instability (CCI/AAI)), Occult Tethered Cord Syndrome (TCS), Chiari Malformation (CM) and Idiopathic Intracranial Hypertension (IIH). The neuraxis comprises the parts of the nervous system (brain, nerves, spinal cord) along the craniospinal axis of the body. Neuraxial tissue includes all tissue structures that comprise, support, sheath, and connect along the neuraxis and peripheral nerves. Altered mechanical loading or vascular supply of neural structures can adversely impact neural health and conductivity, with local and remote effects on inflammation, venous congestion, and muscle control. With EDS characterized by altered structure of the connective tissues found throughout the body including the neural system, altered mechanical properties of the central nervous system (CNS) and its surrounding tissue structures are important considerations in the development and diagnostics of these CNS disorders, as well as response to therapeutic interventions. Experts have identified a need for neuraxial curriculum in medical education and hypermobility-adapted treatment approaches in pain management, neurosurgery, anesthesiology, hematology, gastrointestinal surgery, dermatology, cardiology, dentistry, gastroenterology, allergy/immunology, physical therapy, primary care, radiology and emergency medicine. This paper reviews the interactions between neuraxial biomechanics and pathology related to CNS disorders seen commonly with EDS. First, we provide a concise synthesis of the literature on neuraxial kinematics and fluid dynamics. We then discuss the interplay of these biomechanics and their involvement in clinically-relevant diagnoses and overlapping symptom presentations, modeling physiological reasoning to highlight knowledge gaps, support clinical decision-making, improve multidisciplinary management of hypermobility-associated complexity, and add weight to the call for medical education reform.

Lower urinary tract involvement in Ehlers-Danlos and Joint Hypermobility syndromes: Review of the literature

INTRODUCTION

Ehlers-Danlos syndrome (EDS) and Joint Hypermobility syndrome (JHS) are still poorly understood, with a prevalence of 1/5000 for EDS and 1/500 for JHS. They are characterized by multisystem involvement. Urological involvement has been little studied. The aim was to carry out a review of the literature on the urological involvement of EDS and JHS.

METHOD

A review of the literature was carried out using the following databases: Pubmed, Canadian Hospitals and EMBASE. Search terms were "Ehlers-Danlos" or "Joint Hypermobility" associated with "Urology", "Bladder", "Pelvic Organ Prolapse", "Urinary Retention", "Leak", "Leakage", "Urinary Incontinence", "Urinary Tract Infection" and "Urdodynamic", no filters were added.

RESULTS

Seventy-three articles were included for a total of 259 found. The prevalence of urinary incontinence in EDS is estimated at 50-60%, and that of pelvic organ prolapse (POP) at 29-75%. Bladder diverticula are also frequently reported. For JHS, the prevalence of urinary incontinence is estimated between 40 and 73%, that of POP increased with 73% of stage greater than 2, g-JHS patients are almost 3 times more affected by prolapses (OR=2.37) which seem more severe. Patients with vesicoureteral reflux, most often severe, are more affected by joint hypermobility (OR=2.79). Few studies have been carried out on urological assessment and treatment modalities.

CONCLUSION

EDS patients often have urinary incontinence, pelvic organ prolapse or bladder diverticula. JHS patients frequently have urinary incontinence, pelvic organ prolapse and vesicoureteral reflux.

An overview of Ehlers Danlos syndrome and the link between postural orthostatic tachycardia syndrome and gastrointestinal symptoms with a focus on gastroparesis

There has been an increasingly reported association between Ehlers-Danlos syndrome (EDS), postural orthostatic tachycardia syndrome (POTS) and gastrointestinal disorders. EDS is a hereditary connective tissue disorder which may manifest as a spectrum of symptoms stemming from collagen defects. The prevalence of EDS is estimated to affect 1 in 5000 individuals which underscores its clinical significance. Notably the hypermobile form (hEDS) accounts for the majority of cases. POTS is characterized by orthostatic intolerance with an increase in heart rate on standing in the absence of hypotension. This condition predominantly affects women between 15 and 45 years of age. Gastrointestinal symptoms in the form of reflux, bloating and abdominal pain significant impact this population. Gastroparesis is a chronic disorder involving symptoms of delayed gastric emptying and may be closely associated with hEDS and POTS, and may be underreported. Autonomic dysfunction associated with hEDS has been proposed as the likely mechanism underlying POTS and gastrointestinal dysfunction though a clear pathophysiological process has not been established.

Outcomes of complex abdominal wall reconstruction in patients with connective tissue disorders: a single center experience

INTRODUCTION

Individuals diagnosed with connective tissue disorders (CTD) are known to be predisposed to incisional hernia formation. However, there is a scarcity of data on outcomes for these patients undergoing hernia repair. We sought to describe our outcomes in performing abdominal wall reconstructions in these complex patients.

METHODS

Adult patients with CTD undergoing open, elective, posterior component separation with permanent synthetic mesh at our institution from January 2018 to October 2022 were queried from a prospectively collected database in the Abdominal Core Health Quality Collaborative. We evaluated 30-day wound morbidity, perioperative complications, long-term hernia recurrence, and patient-reported quality of life.

RESULTS

Twelve patients were identified. Connective tissue disorders included Marfan's n = 7 (58.3%), Loeys-Dietz syndrome n = 2 (16.7%), Systemic Lupus Erythematosus n = 2 (16.7%), and Scleroderma n = 1 (8.3%). Prior incisions included three midline laparotomies and nine thoracoabdominal, mean hernia width measured 14 cm, and 9 were recurrent hernias. Surgical site occurrences (SSOs) were observed in 25% of cases, and 16.7% necessitated procedural intervention. All twelve patients were available for long-term follow-up, with a mean of 34 (12-62) months. There were no instances of reoperation or mesh excision related to the TAR procedure. One patient developed a recurrence after having his mesh violated for repair of a new visceral aneurysm. Mean HerQLes scores at 1 year were 70 and 89 at ≥ 2 years; Mean scaled PROMIS scores were 30.7 at 1 year and 36.3 at ≥ 2 years.

CONCLUSION

Ventral hernia repair with TAR is feasible in patients with connective tissue disorder and can be a suitable alternative in patients with large complex hernias.

The spectrum of gastrointestinal functional bowel disorders in joint hypermobility syndrome and in an academic referral center

Joint hypermobility syndrome (JHS) is a non-inflammatory hereditary disorder of connective tissue with varied clinical presentations, including frequent joint dislocations, hyperextensible skin, easy bruising, and abnormal paper-thin scar formation. Many of these patients have unexplained gastrointestinal (GI) symptoms. Our aim was to evaluate the prevalence of JHS in a tertiary gastroenterology motility clinic and the spectrum of functional bowel disorders in JHS patients. In this retrospective case series, we screened the medical records of 277 patients seen over 4 years at an academic GI Motility Center. The patients who met the criteria for JHS by Beighton hypermobility score were evaluated for the presence of functional GI disorders by Rome IV criteria. They also underwent gastric emptying study and glucose breath testing for small intestinal bacterial overgrowth. The prevalence of JHS in the study population was 9.7%. The mean age was 27 years, and 92.5% were female. The symptoms experienced by these patients include nausea/vomiting (89%), abdominal pain (70%), constipation (48%), and bloating (18.5%). The disorders associated with JHS include gastroparesis (52%), irritable bowel syndrome (55.5%), and gastroesophageal reflux disease (30%). Also, 10 patients (37%) were diagnosed with postural hypotension tachycardia syndrome secondary to autonomic dysfunction. Approximately 10% of patients with suspected functional bowel disorders have hypermobility syndrome. Hence, it is crucial to familiarize gastrointestinal practitioners with the criteria utilized to diagnose JHS and the methods to identify physical examination findings related to this condition.

Removal of Polymer Clips From the Gallbladder Fossa in a Patient With Ehlers-Danlos Syndrome (EDS) to Treat Mast Cell Activation Syndrome (MCAS): A Case Report

Ehlers-Danlos syndrome (EDS) is a group of hereditary disorders characterized by fragility of connective tissue. Clinical manifestations of the disorder involve the skin, joints, blood vessels, and other internal organs. We report the case of a 29-year-old female suffering from EDS and mast cell activation syndrome (MCAS). Her history includes multiple orthopedic surgeries leading to the worsening of her symptoms. This was determined to be due to medical implants placed during her multiple procedures predisposing her to severe immunological reactions. This case report emphasizes the importance of meticulous surgical intervention when managing patients with EDS.

OUP accepted manuscript

Isolated small bowel perforation is low in the differential diagnosis of abdominal pain in the young, relatively healthy patient. It is, however, a rare manifestation of type IV (vascular) Ehlers-Danlos syndrome (EDS). In addition, there is no general consensus on the management of GI manifestations in patients with type IV EDS. We present the case of a 31-year-old male with history of type IV EDS, presenting with acute onset abdominal pain. Imaging was notable for intra-abdominal free air and thickened loops of small bowel in the pelvis. The patient underwent exploratory laparotomy with resection of the small bowel perforation with enteroenteric anastomosis. In our literature review, we evaluated gastrointestinal manifestations observed in patients with type IV EDS, management recommendations and potential complications to be mindful of in this population.

Total colectomy in Vascular Ehlers Danlos syndrome a case report and literature review

Introduction

Ehlers Danlos syndromes (EDS) are a group of genetic disorders, characterized by skin hyperelasticity, joint hyperlaxity and tissue weakness. Vascular EDS is rare and is differs from other types of EDS by an inconsistent acrogenic morphotype and the occurrence of severe digestive and vascular complications, which can be lifethreatening.

Case presentation

We report the case of a 27-year-old man with a type IV vascular Ehlers-Danlos syndrome revealed by a colonic perforation after appendectomy for peritonitis secondary to appendicitis. The etiology of the perforation remained a challenge till a genetic research was carried out for COL3A1 gene mutation, which was positive in favor of vascular Ehlers Danlos disease. Then, a totalization of the colectomy with ileorectal anastomosis was performed.

Discussion

Vascular Ehlers Danlos syndrome (VEDS) is due to qualitative and quantitative abnormalities in the synthesis of type III collagen, which is a major constituent of the vessel wall, skin, joint capsules, uterus and gastrointestinal tract, particularly the colon. Colonic perforation, particularly sigmoidal perforation, is the most frequent complication in SEDV and most often precedes the molecular diagnosis. Colonic perforations are uncommon. The Hartmann procedure is a well-established surgical treatment modality, especially for emergency surgery. Given the iterative risk of colonic perforation and anastomotic leakage, preventive treatment by total colectomy with ileo-rectal anastomosis or definitive ileostomy is recommended by several authors.

Conclusion

SEDV is a rare pathology with a difficult diagnosis. However, it should be keeped in mind when there is any spontaneous colonic perforation in the young people.

•

Ehlers danlos syndromes are a group of genetic disorders of the connective tissue.

•

Life expectancy is reduced due to spontaneous vascular rupture or colonic perforation.

•

Colonic perforations are uncommon. They occur in the context of diverticulitis in adults.

•

The diagnosis is difficult because of the rarity of the pathology and the inaccessibility of genetic tests.

•

The surgical management of colonic perforations in ehlers danlos syndromes is not codified.

Vascular Ehlers-Danlos Syndrome: Treatment of a Complex Abdominal Wound with Vitamin C and Mesenchymal Stromal Cells

ABSTRACT

Vascular Ehlers-Danlos syndrome (EDSv) can present with life-threatening surgical complications. The article describes the case of a patient with EDSv who developed total abdominal wound dehiscence and multiple enterocutaneous fistulas. Treatment with IV allogeneic mesenchymal stromal cells (MSCs) and high-dose vitamin C was trialed with success. Near-complete wound healing of the abdominal dehiscence with a 94% reduction in the size of the wound bed occurred. Maturation of the enterocutaneous fistulas also ensued.There is no current consensus on the management of large cutaneous wounds in EDSv. This article discusses the pathophysiology of wound healing with regard to nutrition requirements and growth factors with special reference to collagen deficits in EDSv. A potential therapy with IV vitamin C supplementation and MSCs is proposed following the patient's positive outcome. Medium-dose MSCs and high-dose IV vitamin C may offer significant benefits to complex and problematic wounds.

The dermatological aspects of hEDS in women

Ehlers-Danlos syndrome (EDS) is a group of inherited connective tissue disorders that may present with a wide range of multisystemic symptoms. Hypermobile EDS, one of 13 identified subtypes of EDS, is the only variant without a known associated genetic mutation. A review of the literature suggests the five primary dermatological changes associated with hypermobile EDS are soft skin, atrophic cutaneous scars, piezogenic papules, hyperextensive stretchability, and hematomas. Our paper will address these cutaneous manifestations and delve into how they affect patients (primarily women). Possible consequences and treatment options for these different dermatological changes, as well as other skin manifestations such as livedo reticularis and elastosis perforans serpiginosa, will also be further explored.

Chronic constipation in adults: Contemporary perspectives and clinical challenges. 1: Epidemiology, diagnosis, clinical associations, pathophysiology and investigation

BACKGROUND

Chronic constipation is a prevalent disorder that affects patients' quality of life and consumes resources in healthcare systems worldwide. In clinical practice, it is still considered a challenge as clinicians frequently are unsure as to which treatments to use and when. Over a decade ago, a Neurogastroenterology & Motility journal supplement devoted to the investigation and management of constipation was published (2009; 21 (Suppl.2)). This included seven articles, disseminating all themes covered during a preceding 2-day meeting held in London, entitled "Current perspectives in chronic constipation: a scientific and clinical symposium." In October 2018, the 3rd London Masterclass, entitled "Contemporary management of constipation" was held, again over 2 days. All faculty members were invited to author two new review articles, which represent a collective synthesis of talks presented and discussions held during this meeting.

PURPOSE

This article represents the first of these reviews, addressing epidemiology, diagnosis, clinical associations, pathophysiology, and investigation. Clearly, not all aspects of the condition can be covered in adequate detail; hence, there is a focus on particular "hot topics" and themes that are of contemporary interest. The second review addresses management of chronic constipation, covering behavioral, conservative, medical, and surgical therapies.

A case of vascular Ehlers-Danlos syndrome with a ruptured hepatic artery after surgical treatment of peritonitis caused by the perforation of the colon

Background

Ehlers–Danlos syndrome (EDS) is an inherited disorder that causes connective tissue fragility. The vascular type of EDS (vEDS) caused by defective collagen type III production accounts for 5%–10% of all EDS cases. Patients can develop gastrointestinal or arterial ruptures, which cause poor prognosis. We report a case of a patient who experienced colonic rupture, which was immediately followed by arterial rupture.

Case presentation

A 40-year-old man who had been genetically diagnosed with vEDS 6 years previously was admitted to our hospital with ischemic colitis. After 3 days of conservative treatment, his abdominal pain worsened, and computed tomography (CT) revealed free air in the abdominal cavity. Pan-peritonitis due to perforation of the sigmoid colon was diagnosed. Intraperitoneal lavage and drainage and Hartmann’s operation were urgently performed. Because the patient had confirmed vEDS, we performed the surgery in a protective manner. The postoperative course was initially good, and he was transferred to the general ward 3 days after surgery. However, 5 days after surgery, massive intra-abdominal hemorrhage suddenly occurred, and contrast-enhanced CT showed an aneurysm in the common hepatic artery that had ruptured; this aneurysm was not present before surgery and was far from the surgical field. Although we considered an emergency operation, the patient suddenly experienced cardiac arrest and was unresponsive to resuscitation.

Conclusions

In cases of vEDS, vascular rupture can occur immediately after surgery for intestinal rupture. We recommend paying special attention to vascular complications in patients in their forties, as such complications are the most common causes of death.

Ehlers-Danlos syndrome type IV: a case report of a rare cause of spontaneous sigmoid perforation and enteroatmospheric fistulae in a child

Background

Ehlers–Danlos syndrome (EDS) type IV is a rare subtype of EDS, but has important surgical implications.

Case presentation

Here, we present a case of a spontaneous sigmoid perforation in a 14-year-old boy. He was initially treated with laparotomy, oversew of the sigmoid perforation and a diverting ileostomy. He developed a complete wound dehiscence and enteroatmospheric fistulae. These were managed with a combination of negative pressure wound therapy and Eakin (TG Eakin™) pouch changes. We discuss the clinical features and presentation of EDS type IV, the surgical implications of managing patients with the condition, and the challenges in management of enteroatmospheric fistulae in children.

Conclusions

Ehlers–Danlos syndrome type IV should be considered as a cause of any spontaneous colonic perforation in children.

Surgical Management of Colonic Perforation in a Patient with Vascular Ehlers-Danlos Syndrome with no Family History: A Case Report

Vascular Ehlers-Danlos syndrome (vEDS) is a rare autosomal dominant connective tissue disease. Patients with vEDS are at a high risk of developing severe complications (such as arterial aneurysm, arterial rupture, intestinal rupture) at an early age. We report a case of colonic perforation in a vEDS patient with no family history of that disease. A 28-year-old man with abdominal pain arrived at our hospital in an ambulance. The preoperative diagnosis was panperitonitis due to gastrointestinal perforation. Although his parents had not suffered from vEDS, he had been diagnosed with the disease at 25 years of age because of his history of arterial dissection. We performed an emergency operation using Hartmann's procedure to construct a descending colostomy. There remains a lack of consensus on surgical management in vEDS patients with gastrointestinal perforation because of the limited number of reported cases.

Surgical treatment of abdominal wall weakness and lumbar hernias in Ehlers-Danlos syndrome - Case report

•

Ehlers-Danlos syndrome is a rare and diverse group of connective tissue disorders.

•

Gastrointestinal manifestations are frequent in Ehlers-Danlos syndrome.

•

Few publications have reported on surgical managment of Ehlers-Danlos syndrome.

•

Multiple surgical interventions may be necessary if conservative treatment fails.

Introduction

Ehlers-Danlos syndrome (EDS) is a rare and diverse group of heritable connective tissue disorders. Gastrointestinal manifestations and abdominal pain are frequent in most subtypes of EDS. Conservative treatment is the standard of care.

Presentation of the case

A 43-year-old female patient with genetically confirmed EDS classic subtype presented with diffuse gastrointestinal symptoms (bloating, belching and pain) that were controlled by the patient through inclined posture and external abdominal compression. A standard abdominoplasty with rectus muscle plication and mesh implantation lead immediately to complete relief of symptoms, which allowed the patient to assume an upright posture and resume all daily activities again. After 7 years, the patient was again seen with severe, persistent abdominal pain and inclined posture related to right lumbar herniations, as confirmed by MRI. However, there was no recurrence of the previous abdominal midline weakness and related gastrointestinal symptoms. Following lumbar hernia repair and mesh implantation, the patient was free of abdominal pain and resumed an upright posture again.

Discussion

Although conservative treatment of EDS is primarily recommended and most surgeons are reluctant to operate on these patients except in life threatening situations, we present the successful surgical relief of disabling abdominal symptoms.

Conclusion

Regarding the variability and complexity of symptoms in different subtypes of EDS, a personalized multimodal treatment including surgical approaches should be considered and achieved a significant and long-lasting improvement in quality of life in our patient.

Enteroatmospheric fistula repair in Ehlers-Danlos syndrome type IV: a novel management technique using ABRA device

A 35-year-old man with Ehlers-Danlos syndrome type IV (EDS IV) underwent surgical repair of an enteroatmospheric fistula. Despite the substantially increased operative risk, repair was undertaken in view of his poor quality of life and severe nutritional deficits. Dense adhesions and extremely fragile bowel and vasculature characteristic of EDS IV were encountered intraoperatively. Multiple traction enterotomies and faecal matter leaking from suture holes necessitated leaving the abdomen open for a prolonged period. An Abdominal Reapproximation Anchor device was applied to prevent lateral retraction of the abdominal wall during this time. At relook on day 6, no leak was found, and the abdomen was closed. Two years postoperatively, the patient has an intact abdominal wall, with a vastly improved quality of life. This case illustrates the challenges of operating on patients with EDS IV, and presents a novel technique in managing fistulas in these patients.

The most common comorbidities in patients with Ehlers-Danlos syndrome: a 15-year nationwide population-based cohort study

Objectives: Ehlers-Danlos syndrome (EDS) constitutes a group of connective tissue diseases with variable organ dysfunction. We aimed to examine the comorbidity burden in patients with EDS.Methods: A nationwide population-based cohort study linking data from Danish registers from the year 2000-2014. The EDS cohort was identified using the International Classification of Diseases version 10 (ICD-10) EDS code. The control cohort was formed from the Danish general population by randomly matching the EDS cohort in a ratio of 1:25 by sex and date of birth. Hospital contacts were used to identify the most frequently occurring ICD-10 codes. We investigated the frequencies of the disease categories and unique ICD-10 codes and compared these between the cohorts.Results: The EDS cohort included 1,319 patients and the control cohort 46,700 patients. All disease categories and ICD-10 codes were significantly more frequent within the EDS cohort, especially those related to common manifestations of EDS. Other comorbidities such as asthma, pneumonia, gastrointestinal functional disorders, and hernias were also significantly more common in the EDS cohort.Conclusions: The most common comorbidities in Danish patients with EDS were gastrointestinal functional disorders, hernias, asthma, pneumonia, and osteoporosis. The causality between these comorbidities and EDS should be investigated further.Implications for RehabilitationEhlers-Danlos syndrome constitutes a group of connective tissue diseases causing a variable range of organ dysfunction.The comorbidity burden for patients with Ehlers-Danlos syndrome was unexplored previously.This study showed that the most common comorbidities in Danish patients with Ehlers-Danlos syndrome are gastrointestinal functional disorders, hernias, asthma, pneumonia, and osteoporosis.

Obesity surgery and Ehlers-Danlos syndrome: challenges and considerations based on a case report

Ehlers-Danlos syndrome is a hereditary connective tissue disorder that has gastrointestinal manifestations in over 50% of its cases. We present the first case of bariatric surgery in a patient with Ehlers-Danlos syndrome and outline management challenges in the context of the relevant literature. A 56-year-old man with type IV Ehlers-Danlos syndrome and a body mass index of 41.8 kg/m2 was referred to the bariatric centre of the Churchill Hospital, Oxford, for consideration of surgery for morbid obesity. His comorbidity included type 2 diabetes, hypertension, dyslipidaemia and obstructive sleep apnoea. He underwent a laparoscopic Roux-en-Y gastric bypass. His initial recovery was uneventful and he was discharged on the first postoperative day. Six weeks later, he presented with 43.9% excess weight loss and improved glycaemic control. Three months postoperatively, however, he complained of dysphagia, regurgitation and postprandial pain. A barium meal and gastroscopy suggested the presence of a gastric diverticulum. A surgical exploration was planned. Intraoperative gastroscopy demonstrated an asymmetrical gastric pouch dilatation and the pouch was therefore refashioned laparoscopically. Despite the initial symptomatic relief, two months later he experienced retrosternal pain with progressive dysphagia. Since then, multiple endoscopic dilatations of the gastro-oesophageal junction have been performed for recurrence of symptoms. Finally, a laparoscopic hiatus hernia repair and adhesiolysis was performed resulting in complete relief of patient's symptoms. Bariatric management of patients with Ehlers-Danlos syndrome can prove challenging. The bariatric team must implement a careful management plan including a detailed consent process, a tailored surgical intervention and a follow-up focused on potential gastrointestinal manifestations.

Recognizing and Effectively Managing Hypermobility-Related Conditions

Hypermobility spectrum disorder (HSD) and hypermobile Ehlers-Danlos syndrome (hEDS) can cause widespread or chronic pain, fatigue, and proprioceptive and coordination deficits resulting in functional restrictions. These conditions are common and often unrecognized, and patients are likely to present in physical therapy for musculoskeletal injuries, pain, or coordination deficits. Although physical therapy is considered central to managing these conditions, many patients report pain and iatrogenic injuries due to inappropriate interventions. The diagnostic classification for these conditions was revised in 2017 to supersede previous diagnostic categories of Joint Hypermobility Syndrome and Ehlers-Danlos Syndrome-hypermobility type/type III. It is now known that these conditions affect multiple body systems and not just joints and that patients require a holistic approach. This Perspective article will describe the 2017 diagnostic classification system, clinical presentation, examination, evaluation, and management of patients with HSD/hEDS. Both adult and pediatric cases are presented to illustrate the patient management concepts discussed. This knowledge can lead to more effective management of this patient population.

Natural History and Surgical Management of Colonic Perforations in Vascular Ehlers-Danlos Syndrome: A Retrospective Review

BACKGROUND

Vascular Ehlers-Danlos syndrome is a rare and severe genetic condition leading to spontaneous, potentially life-threatening arterial and digestive complications. Colonic ruptures are a common feature of the disease, but clear recommendations on their management are lacking.

OBJECTIVE

This study aimed to identify surgery-related morbidity and 30-day postoperative mortality after colonic perforation.

DESIGN

This was a retrospective review.

SETTING

A large cohort of patients with vascular Ehlers-Danlos syndrome was followed in a tertiary referral center.

PATIENTS

Between 2000 and 2016, the French National Reference Centre for Rare Vascular Diseases (HEGP, AP-HP, Paris, France) followed 148 patients with molecularly proven vascular Ehlers-Danlos syndrome.

MAIN OUTCOME MEASURES

The primary outcomes measured were surgery-related morbidity and 30-day postoperative mortality.

RESULTS

Of 133 patients with molecularly proven vascular Ehlers-Danlos syndrome, 30 (22%) had a history of colonic perforation and 15 (50%) were males. These subjects were diagnosed with vascular Ehlers-Danlos syndrome at a younger age than patients with a history of GI events without colonic perforation (p = 0.0007). There were 46 colonic perforations, median 1.0 event per patient (interquartile range, 1.0-2.0). Reperforations occurred in 14 (47%) patients, mostly males. Surgical management consisted of Hartmann procedures or subtotal abdominal colectomies, with a nonnegligible rate of reperforation following partial colonic resection (11 patients, 41%).

LIMITATIONS

The main limitations of this work are its retrospective design and that the diagnosis of vascular Ehlers-Danlos syndrome was made after colonic perforations in a majority of patients.

CONCLUSION

Colonic perforations seem more severe in males, with a high rate of reperforation after Hartmann procedure. Subtotal colectomy may reduce digestive morbidity, particularly in male patients. Additional studies are required to identify other predictors of reperforation. See Video Abstract at http://links.lww.com/DCR/A937.

Natural history of gastrointestinal manifestations in vascular Ehlers-Danlos syndrome: A 17-year retrospective review

BACKGROUND AND AIM

Vascular Ehlers-Danlos syndrome (vEDS) is a rare connective tissue disorder due to heterozygous mutations in the COL3A1 gene with a dominant negative effect. Spontaneous bowel perforation and intra-abdominal organ rupture are common complications of vEDS. Other gastrointestinal (GI) manifestations may occur but have not been extensively characterized. We herein describe the natural history of GI events and surgery-related complications in patients with vEDS.

METHODS

A retrospective review of GI events in a large cohort of molecularly proven vEDS patients was conducted, after exclusion of mild forms of the disease.

RESULTS

Of 133 patients, 41% had a history of GI manifestations with 112 events, mean 2.0 ± 1.3 events per patient. There was an earlier occurrence of GI events in men (P 0.008). Cumulative incidence was 58% for all patients, higher in men and in patients with splice-site variants. Recurrence of GI events was reported in more than 50% of patients. Colonic perforation was the first digestive event for 47% of patients. Of 85 GI surgeries, 37 (43%) were complicated with 43 events. Nine deaths were reported in this population.

CONCLUSIONS

Vascular Ehlers-Danlos syndrome is characterized not only by bowel perforation but also by a wide variety of GI complications that occur in close to half (41%) of patients. The pattern of GI fragility seems more severe in males and splice-site variants. Complications of GI surgery are common and are related with tissue fragility/friability.

Hypermobile type Ehlers-Danlos syndrome associated with hypogammaglobulinemia and fibromyalgia: A case-based review on new classification, diagnosis, and multidisciplinary management

Hypermobile type Ehlers-Danlos syndrome (hEDS) is an underdiagnosed connective tissue disorder characterized by generalized joint hypermobility, chronic fatigue, widespread joints pain, and impaired quality of life. Here, we reported the first hEDS complicated by hypogammaglobulinemia. New insights into classification, diagnosis, and proper management of hEDS are also reviewed.

Pediatric Endoscopy and High-risk Patients: A Clinical Report From the NASPGHAN Endoscopy Committee

Pediatric gastrointestinal endoscopy has been established as safe and effective for diagnosis and management of many pediatric gastrointestinal diseases. Nevertheless, certain patient and procedure factors should be recognized that increase the risk of intra- and/or postprocedural adverse events (AEs). AEs associated with endoscopic procedures can broadly be categorized as involving sedation-related physiological changes, bleeding, perforation, and infection. Factors which may increase patient risk for such AEs include but are not limited to, cardiopulmonary diseases, anatomical airway or craniofacial abnormalities, compromised intestinal luminal wall integrity, coagulopathies, and compromised immune systems. Examples of high-risk patients include patients with congenital heart disease, craniofacial abnormalities, connective tissues diseases, inflammatory bowel disease, and children undergoing treatment for cancer. This clinical report is intended to help guide clinicians stratify patient risks and employ clinical practices that may minimize AEs during and after endoscopy. These include use of CO2 insufflation, endoscopic techniques for maneuvers such as biopsies, and endoscope loop-reduction to mitigate the risk of such complications such as bleeding and intestinal perforation. Endoscopic infection risk and guidance regarding periprocedural antibiotics are also discussed.

Spontaneous perforation of small intestine followed by rupture of the cystic artery: the natural history of Vascular Ehlers-Danlos Syndrome

Vascular Ehlers-Danlos Syndrome (VEDS) is a rare autosomal dominant disorder caused by mutations in the COL3A1 or COL1A1 genes. Its mortality is secondary to sudden and spontaneous rupture of arteries or hollow organs. The genotype influences the distribution of arterial pathology with aneurysms of intra-abdominal visceral arteries being relatively uncommon. We describe the case of a young man with probable VEDS who died of a spontaneous rupture and dissection of the cystic artery. The patient initially presented with abdominal pain due to an unrecognized spontaneous perforation of the small intestine complicated by sepsis. We postulate that inflammatory mediators may have triggered the arterial rupture due to remodeling and weakening of vessel walls. The phenotype of the patient’s vascular damage included bilateral spontaneous carotid-cavernous sinus fistulae and dissection with pseudoaneurysm formation of large- and medium-sized arteries, predominantly the abdominal aorta and its branches. The autopsy uncovered a long history of vascular events that may have been asymptomatic. These findings along with a positive family history supported the VEDS diagnosis. Loeys-Dietz, Marfan, and familial thoracic aortic aneurysm and dissection syndromes were ruled out based on the absence of arterial tortuosity, eye abnormalities, bone overgrowth, and the distribution of vascular damage among other features. Interestingly, microscopic examination of the hippocampus revealed a focus of neuronal heterotopia, commonly associated with epilepsy; however, the patient had no history of seizures. The natural course of VEDS involves the rupture and dissection of arteries that, if unrecognized, can lead to a rapid death after bleeding into free spaces.

Dilating Vascular Diseases: Pathophysiology and Clinical Aspects

Atherosclerotic disease of the vessels is a significant problem affecting mortality and morbidity all over the world. However, dilatation of the vessels either in the arterial system or in the venous territory is another vessel disease. Varicocele, pelvic, and peripheral varicose veins and hemorrhoids are aneurysms of the venous vascular regions and have been defined as dilating venous disease, recently. Coronary artery ectasia, intracranial aneurysm, and abdominal aortic aneurysm are examples of arterial dilating vascular diseases. Mostly, they have been defined as variants of atherosclerosis. Although there are some similarities in terms of pathogenesis, they are distinct from atherosclerotic disease of the vessels. In addition, pathophysiological and histological similarities and clinical coexistence of these diseases have been demonstrated both in the arterial and in the venous system. This situation underlies the thought that dilatation of the vessels in any vascular territory should be considered as a systemic vessel wall disease rather than being a local disease of any vessel. These patients should be evaluated for other dilating vascular diseases in a systematic manner.

Pharmacological resources, diagnostic approach and coordination of care in joint hypermobility-related disorders

INTRODUCTION

Joint hypermobility (JH) is the hallmark of many hereditary soft connective tissue disorders, including Ehlers-Danlos syndromes and related disorders, disorders of the TGFβ-pathway, lateral meningocele syndrome, arterial tortuosity syndrome, and cutis laxa syndromes. Contemporary practice separates individuals with isolated, non-syndromic JH from patients with Mendelian syndromes and those with hypermobility spectrum disorders. The latter is a new nosologic entity grouping together individuals with JH and related musculoskeletal manifestations, but lacking inclusion criteria for well-defined and/or single-gene disorders. Area covered: Nomenclature of JH and JH-related disorders are summarized on a practically oriented perspective. Critical areas of clinical management comprise pain; cardiovascular and respiratory issues; fatigue and dysautonomia; bone fragility; and capillary, skin and soft tissue fragility. Medical management stands on low-evidence data. Ongoing preclinical and clinical studies are aimed to reach a more personalized pharmacological approach to the management of the cardiovascular risk, musculoskeletal pain, and reduced bone mass. Expert commentary: Correct classification of patients with JH-related disorders needs a systematic approach, in which a wide array of molecular tests should be intermingled with strong clinical competences in highly specialized settings. A multispecialty, hierarchical approach should be encouraged for optimal coordination of care in systemic phenotypes.

Testicular torsion in a patient with Ehlers-Danlos syndrome

We present a 19-year-old man with a diagnosis of Ehlers-Danlos syndrome (EDS) and a delayed presentation of testicular torsion. EDS is a rare and heterogeneous condition affecting collagen synthesis and presents multiple difficulties in a surgical setting. Management of this case of testicular torsion was complicated by impaired cognition of the patient, difficulty with intubation, a contralateral undescended testis and postoperative bleeding. We discuss the specific challenges faced in this case of testicular torsion with longstanding ischaemia and perioperative considerations of EDS.

Establishment and baseline characteristics of a nationwide Danish cohort of patients with Ehlers-Danlos syndrome

Objectives

The aim of this study was to investigate national prevalence, general demographic characteristics and survival of Danish patients with Ehlers-Danlos syndrome (EDS).

Method

A population-based cohort study was conducted using a database consisting of the entire Danish population alive at any given time between 1 January 2000 and 31 December 2012, based upon longitudinal Danish national registers. All patients with EDS were identified, and the cohort was described by disease prevalence, basic demographic characteristics, mean age at death and mortality for the observational period of 13 years.

Results

The cohort held 1427 unique persons with EDS, giving a national prevalence of 0.02%. The EDS population had a mean ( s . d .) age of 34.9 (18.6) years and comprised 73.9% females and 26.1% males. Of the cohort, 95.9% originated from Denmark and 57% were unmarried. We found that 31.6% of the cohort received state-granted subsidies, of which 77% were in the form of early retirement pension. Regarding educational status, 28.1% of the EDS cohort had completed primary education (⩽10th grade) as their highest educational level, while 71.9% had completed a higher level. During the observation period, 42 patients died, with a mean ( s . d .) age at death of 53.6 (21.7) years.

Conclusion

This study confirmed a small national prevalence of patients diagnosed with EDS and showed that the majority of patients diagnosed are female. The EDS cohort had a lower educational level, mean age and life expectancy compared with the background population and showed a predisposition for receiving state-granted subsidies.

Hypermobile Ehlers-Danlos syndrome (a.k.a. Ehlers-Danlos syndrome Type III and Ehlers-Danlos syndrome hypermobility type): Clinical description and natural history

The hypermobile type of Ehlers-Danlos syndrome (hEDS) is likely the most common hereditary disorder of connective tissue. It has been described largely in those with musculoskeletal complaints including joint hypermobility, joint subluxations/dislocations, as well as skin and soft tissue manifestations. Many patients report activity-related pain and some go on to have daily pain. Two undifferentiated syndromes have been used to describe these manifestations-joint hypermobility syndrome and hEDS. Both are clinical diagnoses in the absence of other causation. Current medical literature further complicates differentiation and describes multiple associated symptoms and disorders. The current EDS nosology combines these two entities into the hypermobile type of EDS. Herein, we review and summarize the literature as a better clinical description of this type of connective tissue disorder. © 2017 Wiley Periodicals, Inc.

Association between diverticular disease and Ehlers-Danlos syndrome: a 13-year nationwide population-based cohort study

PURPOSE

The aim of this study was to examine occurrence and consequences of diverticular disease in patients with Ehlers-Danlos syndrome (EDS) compared with a matched cohort.

METHODS

This nationwide population-based cohort study was conducted using data from medical registers in Denmark from year 2000 to 2012. The EDS cohort was identified using the specific diagnosis code for EDS and was randomly matched in a ratio of 1:20 by sex and date of birth (±1 year) with persons from the Danish general population. The occurrence of diverticular disease and the clinical characteristics of the initial diverticular event were compared between the EDS cohort and the comparison cohort. The first admission with diverticulitis was identified, and severity of diverticulitis, treatment, colonoscopies, length of stay, and 30-day mortality were investigated.

RESULTS

We identified 1336 patients with EDS and matched a control cohort of 26,720 patients. The occurrence of diverticular disease in the EDS cohort (2.0 %) and the comparison cohort (0.68 %) differed significantly (p < 0.001). At the first diverticular event, the majority of patients were women (85 % for EDS and 87 % for the comparison cohort). Mean age, localization, and type of contact did not differ significantly. Admission with diverticulitis (1.0 % for EDS and 0.34 % for the comparison cohort) differed significantly (p < 0.001). We found no significant difference in severity of diverticulitis, treatment, length of stay, or 30-day mortality between the EDS and the comparison cohorts.

CONCLUSIONS

Patients with EDS had an increased occurrence of overall diverticular events and admissions with diverticulitis compared with the general population.

A standardized, evidence-based protocol to assess clinical actionability of genetic disorders associated with genomic variation

PURPOSE

Genome and exome sequencing can identify variants unrelated to the primary goal of sequencing. Detecting pathogenic variants associated with an increased risk of a medical disorder enables clinical interventions to improve future health outcomes in patients and their at-risk relatives. The Clinical Genome Resource, or ClinGen, aims to assess clinical actionability of genes and associated disorders as part of a larger effort to build a central resource of information regarding the clinical relevance of genomic variation for use in precision medicine and research.

METHODS

We developed a practical, standardized protocol to identify available evidence and generate qualitative summary reports of actionability for disorders and associated genes. We applied a semiquantitative metric to score actionability.

RESULTS

We generated summary reports and actionability scores for the 56 genes and associated disorders recommended by the American College of Medical Genetics and Genomics for return as secondary findings from clinical genome-scale sequencing. We also describe the challenges that arose during the development of the protocol that highlight important issues in characterizing actionability across a range of disorders.

CONCLUSION

The ClinGen framework for actionability assessment will assist research and clinical communities in making clear, efficient, and consistent determinations of actionability based on transparent criteria to guide analysis and reporting of findings from clinical genome-scale sequencing.Genet Med 18 12, 1258-1268.

Abdominal wall hernias-A local manifestation of systemically impaired quality of the extracellular matrix

BACKGROUND

Throughout life, inguinal hernia develops in approximately every fourth man, some of whom develop multiple hernias. If patients at risk of developing multiple hernias could be identified by a serologic biomarker, treatment might be able to be tailored and improved. Evidence suggests that abdominal wall hernia formation is associated with altered collagen metabolism. The aim of this study was to evaluate biomarkers for type IV and V collagen turnover in patients with multiple hernias and control subjects without hernia.

METHODS

Venous blood was collected from 88 men (mean age, 62 years) with a history of more than 3 hernia repairs and 86, age-matched men without hernias. Biomarkers for synthesis of collagen type IV (P4NP) and type V (P5CP) as well as breakdown (C4M and C5M) were measured in serum by validated, solid-phase, competitive assays. Collagen turnover was indicated by the ratio between the biomarker for synthesis and breakdown.

RESULTS

Type IV collagen turnover was 1.4-fold increased in patients with multiple hernias compared to control subjects (P < .001), whereas type V collagen turnover was 1.7-fold decreased (P < .001). Diagnostic power of P5CP was 0.83 (95%C.I.:0.77-0.89), P < .001.

CONCLUSION

Patients with multiple hernias exhibit increased turnover of type IV collagen and a decreased turnover of type V collagen, demonstrating systemically altered collagen turnover. Biomarkers for type V collagen turnover may be used to identify patients at risk for or with multiple hernias.

Perisigmoid Abscess Leading to a Diagnosis of Ehlers-Danlos Syndrome Type IV

The Ehlers-Danlos syndromes (EDS) are a group of connective tissue disorders characterized by triad of joint hypermobility, skin extensibility, and tissue fragility. Ehlers-Danlos syndrome type IV places patients at risk for life-threatening, spontaneous, vascular or visceral rupture due to reduced or abnormal secretion of type III collagen. We present an adolescent male who was found to have a perisigmoid abscess with a fistula connecting to adjacent sigmoid colon secondary to undiagnosed EDS type IV. Conservative management with antibiotics and bowel rest was pursued to allow for elective resection for his acute complicated diverticulitis at a safer time.

Perioperative Hemostatic Management in Ehlers-Danlos Syndrome: A Report of 2 Cases and Literature Review

Ehlers-Danlos syndrome (EDS) is associated with easy bruising and bleeding complications in the majority. Although bleeding complications are frequently observed during surgery in these patients, the perioperative hemostatic prophylaxis of patients with EDS is not standardized. We present 2 cases of effective perioperative hemostatic management of patients with EDS and review the literature to raise awareness of hemostatic issues during surgery and discuss medical options to consider for perioperative hemostatic management based on our clinical experience and literature review.

Gastrointestinal and nutritional issues in joint hypermobility syndrome/Ehlers-Danlos syndrome, hypermobility type

Gastrointestinal involvement is a well known complication of Ehlers-Danlos syndromes (EDSs), mainly in form of abdominal emergencies due to intestinal/abdominal vessels rupture in vascular EDS. In the last decade, a growing number of works investigated the relationship between a wide spectrum of chronic gastrointestinal complaints and various EDS forms, among which the hypermobility type (a.k.a. joint hypermobility syndrome; JHS/EDS-HT) was the most studied. The emerging findings depict a major role for gastrointestinal involvement in the health status and, consequently, management of JHS/EDS-HT patients. Nevertheless, fragmentation of knowledge limits its impact on practice within the boundaries of highly specialized clinics. In this paper, literature review on gastrointestinal manifestations in JHS/EDS-HT was carried out and identified papers categorized as (i) case-control/cohort studies associating (apparently non-syndromic) joint hypermobility and gastrointestinal involvement, (ii) case-control/cohort studies associating JHS/EDS-HT and gastrointestinal involvement, (iii) case reports/series on various gastrointestinal complications in (presumed) JHS/EDS-HT, and (iv) studies reporting gastrointestinal features in heterogeneous EDS patients' cohorts. Gastrointestinal manifestations of JHS/EDS-HT were organized and discussed in two categories, including structural anomalies (i.e., abdominal/diaphragmatic hernias, internal organ/pelvic prolapses, intestinal intussusceptions) and functional features (i.e., dysphagia, gastro-esophageal reflux, dyspepsia, recurrent abdominal pain, constipation/diarrhea), with emphasis on practice and future implications. In the second part of this paper, a summary of possible nutritional interventions in JHS/EDS-HT was presented. Supplementation strategies were borrowed from data available for general population with minor modifications in the light of recent discoveries in the pathogenesis of selected JHS/EDS-HT features.

Clinical Features and Colonic Motor Disturbances in Chronic Megacolon in Adults

BACKGROUND

Chronic megacolon is a rare disease of the colonic motor function characterized by a permanent increase in colonic diameter.

METHODS

We reviewed electronic medical records of all patients diagnosed with chronic megacolon from 1999 to 2014 at Mayo Clinic. Our aim was to summarize clinical and motility features, including colonic compliance and tone measured by colonic barostat-controlled 10-cm-long infinitely compliant balloon. Colonic compliance curves were compared to healthy control (40) and disease (47) control groups.

RESULTS

Among 24 identified patients, the mean maximal colonic diameter on abdominal radiograph was 12.7 ± 0.8 cm. The cause of megacolon was idiopathic in 16 of 24 and secondary in 8 of 24. A relatively high prevalence (10/24) of comorbid pelvic floor dyssynergia was identified. At the time of this report, 16 patients had undergone colectomy. In general, megacolon presented high fasting colonic volume at relatively low pressures (16-20 mmHg), suggesting high colonic compliance; similarly, volumes at operating pressures that ensured apposition of the balloon to the colonic wall suggested low colonic tone. Median balloon volume at 44 mmHg distension was 584 mL (IQR 556.5-600) in patients with megacolon compared to 251 mL (212-281) in healthy, 240 mL (207-286) in functional constipation, and 241 mL (210.8-277.5) in diarrhea-predominant irritable bowel syndrome controls. Colon's tonic response to feeding was generally intact, and there was frequently maintained phasic contractile response to feeding.

CONCLUSIONS

Chronic megacolon is a severe colonic dysmotility, manifesting radiologically with increased colonic diameter; it can be proven by measuring colonic compliance and typically requires colectomy because of failed medical therapy.

Recommendations for anesthesia and perioperative management in patients with Ehlers-Danlos syndrome(s)

Ehlers-Danlos syndrome (EDS, ORPHA98249) comprises a group of clinically and genetically heterogeneous heritable connective tissue disorders, chiefly characterized by joint hypermobility and instability, skin texture anomalies, and vascular and soft tissue fragility. As many tissues can be involved, the underlying molecular defect can manifest itself in many organs and with varying degrees of severity, with widespread implications for anesthesia and perioperative management. This review focuses on issues relevant for anesthesia for elective and emergency surgery in EDS. We searched the literature for papers related to all EDS variants; at the moment most of the published data deals with the vascular subtype and, to a lesser extent, classic and hypermobility EDS. Knowledge is fragmented and consists mostly of case reports, small case series and expert opinion. Because EDS patients commonly require surgery, we have summarized some recommendations for general, obstetrical and regional anesthesia, as well as for hemostatic therapy.
