Complicated Littre's umbilical hernia with normal Meckel's diverticulum: A case report and review of the literature

Littre's Umbilical Hernia in a Child: A Case Report and Scoping Review

Littre's umbilical hernia (UH) is a rare disease, the third most common Littre hernia. Most case reports interest adult patients. We reported the case of a four-year-old girl with anemia and symptomatic UH, with an incidentally diagnosed Meckel's diverticulum (MD) containing pancreatic ectopic tissue. We reviewed case reports on Littre's umbilical hernia without a date or language restriction. Including our patient, 21 cases were reviewed, of whom 15 (71.4%) were adults and 13 (61.9%) were males. Complicated umbilical hernia occurred in 13 patients (61.9%) and symptomatic MD in two children (9.5%). Investigations preoperatively diagnosed two patients (9.5%). Eighteen patients (85.7%) underwent open surgery, Meckel's diverticulum removal was performed in 18 patients (85.7%), and primary umbilical hernia repair was performed in 16 (76.2%). Ectopic tissue was present in four patients (19.1%), and long-term outcomes were excellent in all patients.

Incarcerated Littre's Umbilical Hernia: A Case Report

Littre's hernia is an extremely rare type of hernia which has Meckel's diverticulum as its content. A 63-year-old male, presented to the emergency department with chief complaints of swelling and pain around the umbilicus. The patient was diagnosed with an incarcerated umbilical hernia. Following the emergency laparotomy, the intraoperative finding depicted an umbilical Littre's hernia. The patient underwent open Meckel's diverticulectomy with mesh repair. Preoperative diagnosis of Littre's hernia is unlikely due to its low incidence and lack of specific radiological and clinical findings, but the role of computed tomography scan and ultrasound are important in differentiating between strangulated or incarcerated bowel and omentum and in guiding the urgency of operative management.

Umbilical Littre hernia: A rare case report of an acute abdomen

INTRODUCTION

Littre's hernia (LH) is due to the presence of a Meckel's diverticulum (MD) in a hernial sac. It is an extremely rare condition in less than 1 % of all MD cases. It is often asymptomatic and is diagnosed incidentally during routine surgery for hernia repair. Surgery is the main treatment. Although the management of uncomplicated MD remains controversial, MD's management in the setting of either bowel obstruction or of Littre's hernia is done according to the clinical principles combined with the availability of local expertise.

PRESENTATION OF CASE

We report a case of an 11-year-old boy presented to the emergency room with a diagnosis of acute obstructive syndrome. Radiological exams were inconclusive. Intra-operatively findings showed a strangulated MD trapped in a small umbilical hernia. A simple wedge resection, followed by a primary closure of the remaining defect was performed. During 12 months of observation the patient remains in good condition.

DISCUSSION

LH is an uncommon type of abdominal wall hernia. Preoperative diagnosis is difficult. Even abdominal ultrasound and computed tomography (CT) cannot reveal the right diagnosis and it is generally performed intraoperatively. The main treatment is surgery. Repair of a Littre hernia requires both management of Meckel's diverticulum and repair of the hernia with sutures or mesh.

CONCLUSION

LH is a very rare type of hernia. Diagnosis is very difficult. All surgeons should be aware of this type of hernia to avoid life-threatening complications. The application of hernia repair recommendations for children may anticipate the happening of complicated LH.

An unusual form of incisional hernia: A case report of Littre's hernia

INTRODUCTION

Littre's hernia (LH) is a rare condition involving Meckel's diverticulum within a hernia sac, with an incidence of <0.1 % of all complicated hernias. To this day, only a few case reports have been published concerning this entity.

CASE PRESENTATION

A 48-year-old patient with a history of four midline C sections and an incarcerated incisional midline hernia was admitted to the emergency department for small bowel obstruction evolving for 12 h. Examination revealed an incarcerated midline incisional hernia. An abdominal CT scan was performed, showing a multi-orifice incisional hernia with a small bowel loop and a 3 cm abscess. The patient underwent an urgent midline laparotomy. During surgery, we found a small bowel loop with a perforated Meckel's diverticulum, located 50 cm from the ileocaecal valve, associated with a 3 cm abscess. Surgical drainage of the abscess, resection of 20 cm of small bowel, including the diverticulum, and an appendicectomy were performed. The incisional midline hernia was managed by herniorrhaphy. The post-operative course was uneventful.

CLINICAL DISCUSSION

Surgeons need to keep in mind the possibility of discovering Meckel's diverticulum in a hernia sac in every incarcerated hernia. Complete history intake and careful physical examination are important to uncover signs prompting clinical suspicion. Littre's hernia is rare and difficult to diagnose, with no distinguishing clinical features or physical signs.

CONCLUSION

Managing LH involves treating the symptomatic Meckel's diverticulum with various resection methods and the hernia itself, with mesh application being a controversial topic. Prophylactic resection remains debatable among experts.

Incidental Meckel's Diverticulum in Umbilical Hernia

The presence of a Meckel's diverticulum in the hernial sac is called a Littre's hernia. It is a rare complication of Meckel's diverticulum. We present a 56-year-old male patient who complained of swelling in the umbilical region. After the clinical examination and imaging studies, we diagnosed the patient with a partially reducible umbilical hernia. The patient underwent exploration and was found to have omentum, Meckel's diverticulum, and part of the ileum within the sac. The patient underwent segmental resection of the bowel, primary repair of the hernial defect, and onlay meshplasty. Postoperatively, the patient did not develop any complications.
