Jejuno-ileal diverticulitis: Etiopathogenicity, diagnosis and management

A Rare Case of Terminal Ileal Diverticulitis: Clinical Presentation, Diagnosis, and Management

Diverticulitis is an acute inflammatory condition that typically affects the colon. Diverticulitis of the ileum is rare, with most cases reported in the terminal ileum, and is often triggered by an underlying infection, obstruction, or ischemia. Clinically, ileal diverticulitis presents with symptoms similar to colonic diverticulitis, such as abdominal pain, fever, and constipation. Symptoms can also mimic other conditions, including Crohn's disease and appendicitis. Thus, diagnosis is difficult and often delayed, leading to abscess, fistula formation, and acute abdomen. Diagnosing ileal diverticulitis requires a high clinical suspicion, which is depicted in this case of terminal ileal diverticulitis complicated by sepsis and the patient's underlying medical comorbidities.

Non-Meckel Ileal Diverticulum Incarcerated Within a Strangulated Inguinal Hernia: A Case Report

Non-Meckel small bowel diverticula, particularly ileal diverticula, are rare, especially when incarcerated within an inguinal hernia sac. This case involves an 80-year-old man who presented with a newly noticed tender, irreducible lump in his left groin, accompanied by symptoms of bowel obstruction such as inability to pass flatus and vomiting. His medical history included a previous right inguinal hernia repair. Physical examination and laboratory tests indicated a strangulated hernia, which was confirmed by a contrast-enhanced computed tomography scan showing small bowel obstruction at the neck of the left inguinal hernia. The patient underwent a laparoscopic mesh repair, during which a non-Meckel ileal diverticulum was discovered within the hernia sac alongside a bruised but viable segment of the small bowel. The incarcerated diverticulum was gently reduced, and the hernia was successfully repaired using a mesh. The patient had an uneventful recovery and was discharged in a stable condition. This case highlights the importance of considering rare causes of small bowel obstruction in elderly patients presenting with hernias. Prompt imaging and surgical intervention are crucial to prevent serious complications such as bowel ischemia and perforation. The successful laparoscopic approach demonstrated minimal invasiveness and facilitated a swift postoperative recovery, underscoring its effectiveness in managing such uncommon clinical scenarios.

Complete resolution of perforated jejunal diverticulitis after nonoperative management

The authors report a case of perforated jejunal diverticulitis that was managed nonoperatively in a 60-year-old man. Nonoperative management of perforated jejunal diverticulitis is uncommon but possible, and necessitates close follow up to ensure complete resolution.

Left side jejunal diverticulitis: US and CT imaging findings

Small bowel jejunoileal diverticulosis is an uncommon and usually asymptomatic condition. Complications may occur such as acute diverticulitis including infection or perforation, bleeding, small bowel obstruction and volvulus. Herein we report a case of a 76 years-old woman with acute left side abdominal pain and tenderness. A clinical suspected diagnosis of colonic diverticulitis was formulated. She underwent Ultrasound that revealed a collapsed small bowel loop with a large sac-like out-pouching lesion with mixed content (fluid and pockets of air) associated to hyperechogenicity of perilesional fat. Because of the atypical US findings, the patient underwent abdominopelvic CT that confirmed that the large sac-like out-pouching was a jejunal inflamed diverticulum. The patient underwent emergency surgery. Radiologist should be aware of imaging findings of jejunoileal diverticulitis in order to achieve a prompt diagnosis.

Perforated jejunal diverticulitis in the setting of biologic therapy presenting as transverse Colon diverticulitis: A case report

INTRODUCTION

Small bowel diverticula are a rare entity and are mostly found in the duodenum on diagnosis. Some common complications of this pathology include bleeding, obstruction, diverticulitis, and perforation. Furthermore, there is growing evidence supporting an association between biologic therapies and spontaneous intestinal perforation.

PRESENTATION OF CASE

We present a case of a 79-year-old female on prednisone, hydroxychloroquine, and tofacitinib for rheumatoid arthritis who was misdiagnosed with transverse colonic diverticulitis and eventually found to have perforated jejunal diverticulitis on laparotomy.

DISCUSSION

While tofacitinib has been associated with spontaneous intestinal perforation, it has not been documented as an aggravating factor in small bowel diverticular disease.

CONCLUSION

It is imperative to maintain a high index of suspicion for this pathology in immunosuppressed patients with an atypical presentation of diverticular disease.

Diverticulitis aguda del intestino delgado como causa infrecuente de abdomen agudo en el adulto mayor: reporte de caso

Introducción. El dolor abdominal es uno de los principales motivos de admisión a urgencias y una de las causas más frecuentes es la enfermedad diverticular, que aumenta su prevalencia en el adulto mayor. Sin embargo, la diverticulitis del intestino delgado es una enfermedad infrecuente y en la mayoría de casos es asintomática. No obstante, la perforación de un divertículo intestinal es una complicación común de esta patología, por lo que debe ser considerado como un diagnóstico diferencial de abdomen agudo en este grupo poblacional. Caso clínico. Paciente masculino de 71 años, quien consultó por dolor abdominal de inicio súbito, con signos de irritación peritoneal al examen físico. Dado su deterioro hemodinámico fue llevado a cirugía y en la laparotomía exploratoria se halló una diverticulitis aguda perforada de yeyuno e íleon distal. Resultados. El paciente cursó con una adecuada evolución postoperatoria, sin reingresos. Conclusión. La diverticulitis aguda yeyuno-ileal es una causa importante, pero no frecuente de perforación intestinal. Hay muy pocos casos reportados en la literatura, lo que la convierte en un reto diagnóstico para el médico de urgencias y el cirujano general. No obstante, debe ser considerado como un diagnóstico diferencial en adultos mayores con abdomen agudo.

A rare case of perforated jejunal diverticula of an uncommon origin

Jejunal diverticula are often asymptomatic and rare, so they can go unnoticed until serious complications like obstruction, bleeding, perforation, volvulus, or diverticulitis occur. Elderly people over 60 are more likely to have this condition.

Jejunal diverticulosis presenting as intestinal obstruction-A case report of a rare association

Jejunal diverticula are rare medical conditions with an incidence of 0.3%-2.5%, mostly discovered perioperatively. Our patient, 60 years old female, presented in an emergency with complaints of constipation, vomiting, abdominal pain, and distension. On examination, her abdomen was markedly distended with generalized tenderness. An erect abdominal X-ray revealed multiple air-fluid levels, which suggests small bowel obstruction. A diagnosis of jejunal diverticula was made on exploratory laparotomy. No evidence of granuloma or malignancy was seen on histopathological examination. Segmental resection of the affected jejunum was carried out, followed by end-to-end primary anastomosis. The patient was discharged on postoperative Day 6 with complete recovery at 2 weeks follow-up visit.

Complicated jejunal diverticulitis: A case report and review of literature

Jejunal diverticulitis is an uncommon pathology wherein a delay in diagnosis can lead to significant morbidity and mortality. We report a case of such diverticula requiring operative management, after patient failed non-operative management, likely due to advanced jejunal inflammation from a delay in diagnosis and subsequent management.

A rare case of terminal ileum diverticulosis in a-32-year old woman

Introduction

and importance: Acquired small bowel diverticulosis is rare 1% and the ileum is the less frequent occurring site 15%. Most cases were multiple and asymptomatic. This is the first case of perforated terminal ileum diverticula in a 32-year-old woman and successfully managed surgically.

Case presentation

We describe a rare case of terminal ileal diverticulosis, one of the diverticula was perforated, in a 32-year-old female who presented with a 2-days history of sudden epigastric and periumbilical pain and had been managing surgically. At surgery, we found multiple diverticula, one of them was perforated. Microscopically, the specimen confirmed that the diagnosis was diverticulosis.

Conclusion

Diverticulosis should be included in the differential diagnosis of a sudden epigastric and periumbilical pain even in this age.

•

Small bowel diverticulosis is not common comparing with colonic diverticulosis and occurs in up to 1% of patients.

•

Diverticula is more common in males than females.

•

We report a case of terminal ileum diverticulosis and a perforation of one diverticulum.

Jejunal diverticulitis: A new case report and a review of the literature

Jejunal-Ileal Diverticulosis Induced Witzel Tube Failure: A Rare Cause of Small Bowel Obstruction

Jejunal diverticulitis is a rare form of diverticulosis that occurs in the jejunum. Ileal diverticula are a type of false diverticula that are mostly asymptomatic and are usually discovered on imaging as incidental findings. Jejunal diverticula are typically difficult to diagnose pre-operatively due to their indolent and asymptomatic nature. The etiology of this condition is unclear, although some are believed to be genetic if diffuse. When symptomatic, patients may present with vague symptoms. This requires a high index of clinical suspicion because imaging results are usually negative. Management often requires surgical intervention in the presence of complications. Our case highlights a rare case of jejunal-ileal diverticulosis with inward involution causing Witzel tube (jejunostomy tube, or J-tube) obstruction and failure, along with partial obstruction of the small bowel.

Small bowel diverticula in elderly patients: a case report and review article

Background

Small intestine diverticula are rare findings that were mostly reported in the elderly population as asymptomatic findings. However, they can also present with a wide range of symptoms (bloating, early satiety, chronic abdominal discomfort, and diarrhea/steatorrhea) or complications (gastrointestinal bleeding, small bowel obstruction, acute diverticulitis, or perforation) which in turn warrant medical treatment or urgent surgical intervention.

Case presentation

This is a case report of an 84-year-old female who presented with an acute surgical abdomen. An exploratory laparotomy revealed complicated small bowel diverticula with a jejunal diverticulum perforation, for which a diverticulectomy was performed.

Conclusions

Throughout this paper, we are aiming to outweigh the consideration of the possibility of complicated small bowel diverticula as a differential in the evaluation of any acute abdomen, especially in the elderly, which warrants emergency surgical management.

Operative Management of Perforated Jejunal Diverticulitis

Small jejunal diverticulitis is very rare, presenting in 0.06% to 1.3% of the population. Many patients remain asymptomatic or have nonspecific symptoms such as malabsorption and abdominal pain, making diagnosis complicated. Up to 6% of patients present with acute perforation. Here, we present such a case involving a 69-year-old female who presented with altered mental status due to sepsis and generalized peritonitis from a perforated jejunal diverticulum that was successfully managed with definitive surgery. We highlight the importance of maintaining a broad differential, early resuscitation, and prompt surgical management in complicated jejunal diverticulitis. Although adjunctive studies such as computed tomography may be helpful in stable patients, definitive surgery was both diagnostic and therapeutic in this case.

Multiple Jejunal Diverticulosis Complicated by Perforation: Case Report and a Brief Literature Review

Background Multiple small-bowel diverticulosis comprises a rare entity with probable underestimated incidence, and that may be the reason why it is sometimes overlooked when managing cases with peritonitis.

Case report In the present paper, we report the case of a 76-year-old male presenting abdominal pain and fever in an acute setting. Computed tomography (CT) scans revealed jejunal thickening and numerous images of saccular addition that were interpreted as jejunoileal diverticulitis. After an initial period of clinical treatment, surgical management was indicated based on a worsening clinical picture and the presence of an extraluminal focus of gas detected in a subsequent CT scan. Through a laparoscopic approach, multiple small-bowel diverticula and a tamponade perforation were found. A segmental intestinal resection was performed, and the patient was discharged after a ten days.

Conclusions Multiple jejunal diverticulosis is a rare condition that should be remembered in the setting of an acute abdomen. As it prevails among older patients, early diagnosis with radiological aid is crucial to establish the most adequate management, including intestinal resection, if necessary.

Surgically Managed Perforated Jejunal Diverticulitis

A 71-year-old male with a past medical history significant for chronic constipation presented to the emergency department for acute onset of severe abdominal pain. On presentation, the patient appeared to be in distress, exemplifying signs of peritonitis despite vital signs being grossly benign. CT scan established the diagnosis of a perforated jejunal diverticulitis. Initially, the patient was managed conservatively with IV fluids, antibiotics, and pain control medications. Diagnostic imaging in tandem with the patient's failure to improve incited surgical intervention with a jejunal resection and establishment of a primary anastomosis. This case illustrates additional differential diagnoses necessary for consideration in an elderly patient presenting with an acute abdomen. 

Perforated Jejunal Diverticulitis: a rare cause of acute abdominal pain

It is imperative for surgeons to have a heightened awareness of complications of jejunal diverticular disease so that they can act quickly and contribute to a successful clinical outcome for their patients.

Small bowel diverticulitis - Spectrum of CT findings and review of the literature

PURPOSE

To review the CT findings and complications of small bowel diverticulitis (SBD) and discuss clinical presentations and outcomes.

METHODS

A text search of radiology reports within our health system for cases of small bowel diverticulitis yielded 95 cases. All cases were reviewed by an abdominal radiologist with equivocal cases reviewed by a second abdominal radiologist for consensus. Retrospective analysis of CT imaging findings was performed on 67 convincing cases of SBD.

RESULTS

Small bowel diverticulitis most often affected the jejunum (58%) and the duodenum (26%). The most common imaging feature was peridiverticular inflammation manifested by peridiverticular edema, diverticular wall thickening, bowel wall thickening, and fascial thickening. Edema was typically seen along the mesenteric border of the bowel with relative sparing of the anti-mesenteric side. When a prior CT was available, the affected diverticulum was identified in 95% of cases. Fecalized content within the affected diverticulum was observed in 51% of cases. Perforation (6%) and abscess (6%) were the most common complications.

CONCLUSION

Small bowel diverticulitis is an uncommon cause of abdominal pain which can mimic an array of abdominal pathologies, although the reported mortality rate of 40-50% may no longer be accurate. The "fecalized diverticulum" sign can be helpful in identifying the culprit diverticulum and aid diagnosing SBD. Findings of perforation and or abscess formation are critical as they may impact management.

Thigh phlegmon as a first sign of a ruptured pelvic presacral abscess caused by ileal diverticulum fistula: A case report

•

Ileal diverticulum rarely causes pelvic abscess.

•

Pelvic abscess rarely causes thigh phlegmon.

•

Rupture of presacral abscess to extra-pelvic site carries high mortality.

•

Intrapelvic pathology has to be considered in patients with thigh phlegmon.

Introduction

Ileal diverticula usually remain asymptomatic. If complicated, they may present as intra-abdominal or pelvic abscess. Abscess formation in the presacral space is very rare. The rupture of abscess and spread of pus to extra-pelvic sites through anatomical structures of the pelvis is extremely rare. It carries high mortality if not diagnosed on time.

Case presentation

We report a case of 52-year-old woman presented with thigh phlegmon and septic condition. The CT scan revealed free air in the left leg and pelvic presacral fluid collection descending to extra-pelvic direction through the greater sciatic notch. Moreover, ileal fistula to presacral abscess was suspected. Multiple incisions and fasciotomies were urgently performed to treat thigh phlegmon. Subsequently, laparotomy was carried out and ileal fistula was excised. Histological examination of the surgical specimen demonstrated that the fistula to presacral abscess has formed due to perforated ileal diverticulum. 3 years after the surgery the patient remains healthy without recurrence.

Discussion

Rupture of presacral abscess to extra-pelvic site due to ileal diverticulum fistula is an extremely rare case, to our best knowledge, never reported in literature. Due to a rare occurrence and early septic complications if diagnosed late, this condition carries a high mortality rate.

Conclusion

Intrapelvic pathology must be considered in patients with thigh phlegmon in order to prevent complications and associated mortality.

Small Intestinal Diverticulosis: A Rare Cause of Intestinal Perforation Revisited

Jejunoileal diverticulosis (JID) is a rare and nonspecific symptomatic disease. It is usually an acquired condition associated with false diverticula and integrated with colonic diverticulosis which can be diagnosed incidentally or later with complications. A sixty-nine-year-old male presented with sudden onset generalized abdominal pain. Computed tomography (CT) imaging was suggestive of ileal diverticulitis with localized perforation. The patient was treated conservatively with IV fluids and antibiotics and kept nil per orem for three days and discharged after symptoms subsided. The patient returned with a similar presentation but with a greater intensity. CT with oral contrast revealed evidence of distal ileal perforation. The terminal ileum was resected, and a double barrel ileostomy was created. Six months later, the stoma was reversed after resecting 50 cm of proximal terminal ileum which included all diverticula. The patient had a smooth postoperative recovery. Small bowel diverticulitis is generally managed conservatively unless the patient's clinical condition mandates urgent exploration. This report may add knowledge and lead to a change in clinical practice.

Penetration and Perforation of Terminal Ileum Diverticulitis

Background

Terminal ileum diverticulitis is a rare clinical disease. It can frequently mimic other processes, such as acute appendicitis. Diagnosis and therapeutic decision making (surgical or conservative treatment) can be complex. We report four interesting cases of terminal ileum diverticulitis. Case Presentation. Case 1: a 55-year-old male presented to us with a 3-day history of severe right lower quadrant pain. Computed tomography (CT) showed penetration of terminal ileum diverticulitis. Following a 7-day conservative treatment, he underwent ileocecal resection. Pathology results revealed a false diverticulum and two in five points of perforated terminal ileum diverticulum. Case 2: a 77-year-old male presented to us with severe right lower quadrant pain and unconsciousness. CT showed penetration of terminal ileum diverticulitis and air in the mesentery. Ileocecal resection was performed 2 days postadmission. Pathology results revealed a false diverticulum and penetrated terminal ileum diverticulum. Case 3: a 61-year-old male presented to us with a right lower quadrant pain for 10 days and fever for 6 days. CT showed penetration of terminal ileum diverticulitis and abscess of the psoas muscle. Puncture and drainage of abscess were performed. Laparoscopic ileocecal resection was performed 30 days postadmission. Pathology results revealed a false diverticulum and penetrated terminal ileum diverticulum. Case 4: a 39-year-old female presented to us with right lower quadrant pain for 9 days, suspicious of appendicitis. CT showed abscess of pericecal area. Puncture and drainage were performed. A drainage tube was located into the cecum through the terminal ileum. Conservative therapy was effective, and she was discharged 23 days postadmission.

Conclusions

All four cases had right lower quadrant pain. Three cases were diagnosed by CT, whereas one was diagnosed by abscess drainage. Two cases required surgical treatment within 3 days, one within about 1 month, and one case did not require surgery. The decision of whether to manage a patient surgically or conservatively is difficult. It is critical not to delay the decision of performing a surgical treatment until each patient reaches a stable general condition.

Rare aetiology of abdominal pain: contained abscess secondary to perforated jejunal diverticulitis

A patient with a history of multiple jejunal diverticulosis (JD) presented with a non-peritonitic abdominal pain and leucocytosis. CT scan showed a thick-walled interloop collection within the left mid-abdomen with dilated bowels and mild diffuse air-fluid levels. Exploratory laparotomy revealed multiple diverticular outpouchings in the mid-jejunum, one of which was perforated, contained within the mesentery. Resection of the contained abscess and primary anastomosis were performed subsequently.

Perforated jejunal diverticulitis: a rare but important differential in the acute abdomen

BACKGROUND

Diverticulosis of the small bowel is rare and, in most cases, discovered incidentally. However, diverticulitis and other complications are important to consider in the differential of an acute abdomen, especially in the elderly population.

CASE PRESENTATION

The patient was a 59-year-old female who presented with acute lower abdominal pain progressing to peritonitis. Computed tomography scan showed a large inflamed and perforated diverticulum on the mesenteric side of the jejunum. Exploratory laparotomy revealed a dilated proximal jejunum with a 5-cm inflamed and perforated mesenteric diverticulum. A small bowel resection with primary anastomosis was performed.

CONCLUSIONS

Jejunal diverticulitis remains a diagnostic challenge. Although uncommon, owing to its high mortality rate, it is an important clinical entity to consider and requires timely management.

Small Bowel Neoplasms: A Pictorial Review

Small bowel tumors are rare and account for approximately 3% of all gastrointestinal tumors in the United States. The incidence of small bowel neoplasms is rising-in particular, there is a rising incidence of small bowel carcinoid tumors. This may in part be due to small bowel lesion identification in an increasing number of cross-sectional imaging studies performed for other indications as well as increased use of advanced imaging techniques to assess specifically for small bowel disease. Diagnosis is a challenge owing to nonspecific clinical manifestation, rare occurrence, and low index of clinical suspicion. Yet, various small bowel neoplasms have characteristic imaging features at CT and MRI when optimal distention of the small bowel is achieved, correlating well with features seen in gross specimens. Understanding the imaging features of small bowel neoplasms is important to improve the radiologist's ability to diagnose and characterize small bowel neoplasms. Most small bowel tumors are clinically silent for long periods, and nearly half of the benign tumors are found incidentally during surgery or at cross-sectional imaging performed for other reasons. The authors review the imaging features of common benign and malignant small bowel neoplasms to aid the radiologist in diagnosis of small bowel tumors. ^©RSNA, 2020.

Perforated isolated jejunal diverticula: a rare cause of acute abdomen

CASE REPORT

A 45-year-old female presented to the surgery emergency department with complaints of pain in the whole abdomen, vomiting and non-passage of flatus and stools for the past one day. Physical examination revealed tachycardia with a normal blood pressure. The abdomen showed diffuse tenderness and guarding and bowel sounds were absent. After appropriate fluid resuscitation, the patient underwent a non-contrast computed tomography, which showed intra-abdominal free air. She was then prepared for exploratory laparotomy. Intraoperatively, three jejunal diverticula were identified at the mesenteric side, with perforation of the distal two. Segmental resection of the jejunum, including three diverticula, with primary end-to-end anastomosis was performed. Histopathology report confirmed the diagnosis of jejunal diverticula.

CONCLUSION

Jejunal diverticula are extremely rare and are usually asymptomatic. However, such presentation warrants their inclusion under the differential diagnosis of acute abdomen, albeit lower down the order. Isolated jejunal diverticular perforation is a rare complication and may present as a surprise intraoperative finding to the operating surgeon.

Jejunal Diverticulosis Complicated by Diverticulitis and Small Bowel Obstruction

Diverticular disease is common in the Western population and can cause considerable morbidity. The prevalence of colonic diverticulosis reaches 60% by the age of 60 years. Small bowel diverticulosis is much rarer and, when present, most commonly occurs in the duodenum. We herein report an elderly woman with jejunal diverticulosis complicated by diverticulitis and small bowel obstruction, who subsequently underwent small bowel resection and primary anastomosis. As demonstrated by this case, jejunal diverticulitis can cause serious complications and given the possibility of recurrence and serious complications, surgical options should be discussed early in the course of medical care. 

Small Bowel Diverticulosis: Pathogenesis, Clinical Management, and New Concepts

PURPOSE OF REVIEW

Small bowel diverticulosis is a well-known clinical entity whose diagnosis and management has evolved in recent years. This review covers pathophysiology, incidence, and prevalence, and it also provides an update on modern diagnosis and management. Meckel's diverticula are covered elsewhere in this volume.

RECENT FINDINGS

CT scan and MRI have largely supplanted barium follow-through for diagnosis. No intervention is needed in asymptomatic individuals. Endoscopic management is playing an increasing role for both bleeding and resection of intraduodenal diverticula, but surgical intervention remains the only definitive intervention for other complications like diverticulitis and small bowel obstruction. Small bowel diverticulosis is an uncommon condition which is associated with numerous possible complications. While endoscopy is playing an increasingly large role in management, surgical resection remains the treatment of choice for most complications. A high index of suspicion is needed in order to diagnose this entity.

Perforated Jejunal Diverticulitis

Small intestinal diverticula are very rare; their incidence ranges from 0.06 to 1.3%, with a higher prevalence after the 6th decade of life. Among these small intestinal diverticula, duodenal diverticula are more frequent, followed by diverticula of the jejunum and ileum. A jejunal diverticulum is usually asymptomatic; sometimes patients complain of vague chronic symptoms like malabsorption, pain, or nausea that easily lead to misdiagnosis. Complications are rarely reported, only in 10% of patients. We report a unique case of a 70-year-old female who presented with confusion due to sepsis from perforated jejunal diverticulitis, which was successfully managed with initial resuscitation and definitive surgery.

Acquired diverticular disease of the jejunum and ileum: imaging features and pitfalls

PURPOSE

To present radiological aspects of jejunoileal diverticulosis and its complications.

RESULTS

Jejunoileal diverticulosis is a relatively rare and underestimated condition, which mostly affects the elderly. It is frequently asymptomatic but it can lead to significant complications requiring surgical treatment. Jejunoileal diverticulosis is far less common than colonic diverticulosis. Acquired small bowel diverticula are often numerous but the complication rate is low. Acute diverticulitis is the most frequent complication; its classic presentation involves the jejunum and is often non-severe. Diverticular hemorrhage is the second most common complication; CT scan examination is essential to determine the accurate topography of the pathological diverticula. Small bowel obstruction can occur through several mechanisms: adhesions, enterolith, and intussusception. Extra-intestinal gas without perforation and "pseudo-ischemic" appearance are non-pathological conditions that are important to diagnose in order to avoid surgery.

CONCLUSION

Jejunoileal diverticulosis usually does not show any symptoms but can lead to diagnostic challenges requiring evaluation by CT. CT scan signs of these complications and some pitfalls must be known.

Jejuno-ileal diverticulitis: A disorder not to underestimate

•

In the paper a rare case of complete and well documented jejunal diverticulitis complicated with perforation and peritonitis is described.

•

Interesting radiological and intraoperative imaging are attached.

•

A carefull and recent literature review has been performed in order to discuss diagnosis and management of jejuno-ileal diverticula and our clinical behavior.

•

From the discussion emerges that the possibility of the presence of small bowel diverticula must be considered in case of occult bleeding non-indentifiable with gastroscopy or colonoscopy.

•

Therapeutic behavior is suggested in case of acute peritonitis due to jejunal diverticula or in case of incidental diagnosis.

Introduction

Jejuno-ileal diverticulitis is an uncommon, acquired clinical entity, with higher prevalence among patients aged between 60 and 70. The condition is usually silent and has been regarded as relatively innocuous. Sometimes patients complain chronic vague symptoms like malabsorption, pain or nausea, that easily lead to misdiagnosis. Acute complications are rare, however, they have been reported and can result in major surgery and high overall mortality.

Case report

We are presenting a case of a 67-year-old patient who presented to our department with abdominal pain and signs of peritonitis. The CT scan displayed an inflammatory mass with a fair amount of free liquid in the abdomen, as well as multiple diverticula at different levels of the intestine. The patient had to underwent immediate surgery, during which a resection of 25 cm jejunum and 80 cm of ileum has been performed.

Conclusion

Jejuno-ileal diverticula are a very uncommon finding that can present formidable challenges in diagnosis and treatment. The course can be completely asymptomatic, however, in rare cases, the condition can lead to severe complications that often require surgery. Multi detector CT (MDCT) with intravenous contrast should always be the modality of choice for investigating a suspect of small bowel diverticula. There are no specific guidelines respect the management of jejuno-ileal diverticulitis, nevertheless, in the acute setting, bowel resection is the treatment of choice.

As well as setting out the rarity of this case, our work intends to review the current literature regarding the epidemiology, natural history, diagnosis and management of jejuno-ileal diverticula

A Case of Perforated Jejunal Diverticulum: An Unexpected Cause of Pneumoperitoneum in a Patient Presenting with an Acute Abdomen

Small bowel obstruction due to a jejunal enterolith: an unusual complication of jejunal diverticulitis

A 91-year-old woman presented with symptoms of acute bowel obstruction supported by clinical findings. A CT of the abdomen was performed which demonstrated jejunal diverticulosis with a single inflamed, wide necked diverticulum. A large enterolith was found to be impacted in the jejunum just distal to the area of inflammation resulting in small bowel obstruction. The patient underwent emergency laparotomy, which confirmed the CT findings. Small bowel resection was performed. The patient had an uneventful postoperative recovery.

Perforated jejunal diverticulitis in a nonagenarian veteran: A case report

•

Jejunal diverticula (JD) are uncommon occurrences that frequently present as a diagnostic dilemma.

•

Most JD are asymptomatic, only 15% present with surgical problems including perforation.

•

Perforation from JD is exceedingly rare.

•

Due to their infrequent clinical significance, complications from JD are difficult to diagnose.

•

In the present report, we discuss a patient who had both sigmoid diverticula and JD.

Introduction

Jejunal diverticular (JD) disease is an uncommon occurrence that frequently present as a diagnostic dilemma. The correct diagnosis from complications of JD is typically made at laparotomy. Most JD are asymptomatic. Of clinically significant small bowel diverticula, only 15% present with surgical problems including obstruction, gastrointestinal bleed, and perforation.

Presentation of case

A 90-year-old man presented to the hospital with abdominal pain. He was clinically stable with local tenderness in the left lower quadrant. Computed tomography demonstrated a dot of free air near the sigmoid and sigmoid diverticula. He continued to have pain and clinically deteriorated following a short period of observation. He underwent an exploratory laparotomy that revealed perforated JD.

Conclusion

Perforation from JD is exceedingly rare. Due to their infrequent clinical significance, complications from JD are difficult to diagnose and therapeutic options are typically made intraoperatively. Any deviation from the expected positive pathway in the management of a suspected entity should prompt an immediate reassessment as well as definitive therapeutic options.

Jejunal pseudodiverticulosis. Three cases report

Jejunal pseudodiverticulosis is an uncommon entity. Pseudodiverticulum are usually asymptomatic and an incidental finding. They can have a less frequent acute onset with perforation, obstruction or bleeding and they could have high morbidity and mortality. We report three patients who debuted with an acute abdomen.

Flare-Up Diverticulitis in the Terminal Ileum in Short Interval after Conservative Therapy: Report of a Case

Diverticulitis in the terminal ileum is uncommon. Past reports suggested that conservative therapy may be feasible to treat terminal ileum diverticulitis without perforation; however, there is no consensus on the therapeutic strategy for small bowel diverticulitis. We present a 37-year-old man who was referred to our hospital for sudden onset of abdominal pain and nausea. He was diagnosed with diverticulitis in the terminal ileum by computed tomography (CT). Tazobactam/piperacillin hydrate (18 g/day) was administered. The antibiotic treatment was maintained for 7 days, and the symptoms disappeared after the treatment. Thirty-eight days after antibiotic therapy, he noticed severe abdominal pain again. He was diagnosed with diverticulitis in terminal ileum which was flare-up of inflammation. He was given antibiotic therapy again. Nine days after antibiotic therapy, laparoscopy assisted right hemicolectomy and resection of 20 cm of terminal ileum were performed. Histopathology report confirmed multiple ileal diverticulitis. He was discharged from our hospital 12 days after the surgery. Colonoscopy was performed two months after the surgery and it revealed no finding suggesting inflammatory bowel disease. Surgical treatment should be taken into account as a potential treatment option to manage the diverticulitis in the terminal ileum even though it is not perforated.

Small bowel diverticulitis: an imaging review of an uncommon entity

In this review, we discuss the clinical and radiologic findings of small bowel diverticulosis, which is infrequently encountered during practice and far less common than colonic diverticulosis. Small bowel diverticulosis can present with a range of emergent symptomatic complications including diverticulitis, perforation, or hemorrhage. Here, we focus on the clinical features, pathogenesis, radiologic findings, and treatment of small bowel diverticulitis. Although not routinely considered in the differential diagnosis of an acute abdomen, prospective radiologic diagnosis of small bowel diverticulitis is important and can lead to conservative treatment thus preventing unnecessary exploratory laparotomy.

Perforated jejunal diverticulum: a rare case of acute abdomen

Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen.

Jejunoileal diverticulosis, a rare cause of ileal perforation - Case report

INTRODUCTION

Jejunoileal diverticulosis (JID) is a rare condition associated with nonspecific symptoms, consisting of acquired false diverticula. It frequently co-exists with colonic diverticulosis. Diagnosis is usually made incidentally or after complications. These include hemorrhage, obstruction and diverticulitis, with or without perforation.

PRESENTATION OF CASE

81-year-old man presented with a painful abdominal mass in the right lower quadrant (RLQ), diffuse abdominal discomfort and fever. Abdominal examination confirmed a well-defined mass in the RLQ without rebound tenderness. Laboratory analysis revealed elevated inflammatory markers and CT scan showed a cavitated lesion with an air-fluid level in the RLQ, without evidence of intraperitoneal free air or fluid. Admitted for conservative treatment, failure to improve led to laparotomy on the 6th day of hospitalization, with identification of jejunoileal diverticulosis complicated with diverticulitis and walled-off perforation. We performed segmental enterectomy.

DISCUSSION

The incidence of JID is estimated at 0.2-7% and it is usually diagnosed in the sixth/seventh decade of life. From a diagnostic perspective, JID is a challenging disorder, without reliable diagnostic tests. Diverticulitis is the most common complication. Perforation generally causes only localized peritonitis, as involved diverticula are often walled off by the surrounding mesentery. In selected cases, medical therapy may suffice. For all other patients prompt laparotomy with segmental intestinal resection is the treatment of choice.

CONCLUSION

JID remains under diagnosed. When it presents as an acute complication it may require immediate surgical intervention. In an elderly person, especially with known gastrointestinal diverticulosis, one must have a high index of suspicion for perforation.

Abdominal pain and faeculent vomiting in a 64-year-old woman

A 64-year-old woman with a previous right colectomy presented with severe epigastric abdominal pain and nausea of several weeks' duration, which then escalated to projectile faeculent emesis. During her clinical course, she remained afebrile with normal vital signs. Physical examination revealed abdominal distension, moderate tenderness in the bilateral upper quadrants and provoked voluntary abdominal wall guarding. Haematology and laboratory chemistries were only notable for a mild (14.6 K/μL) leucocytosis. Acute abdominal plain radiological series revealed dilated small bowel loops and possible pneumoperitoneum. Abdominal CT demonstrated a mechanical small bowel obstruction and no extraluminal air. An exploratory laparotomy was performed, revealing an obstructing enterolith related to actively inflamed jejunal diverticulitis (complicated JD). This case report aims to describe the non-specific presentation of a poorly understood disease entity that presents a diagnostic and therapeutic challenge for the medical community.
