Primary torsion of the vermiform appendix and undescended cecum treated by video-assisted transumbilical appendectomy

Torsion of cecal appendix. Report of the first Italian case and review of the literature

In pediatric patients appendicitis is the most common cause of abdominal pain and surgery. Torsion of vermiform appendix is a rare cause, clinically indistinguishable from appendicitis with usually an intraoperative diagnosis. The first description of vermiform appendix torsion was made by Payne in 1918. Clinical presentation is similar to acute appendicitis. Preoperative investigations play a minimal role. Etiology of this condition is unclear, but is possible to distinguish a primary and a secondary torsion. We report a case of 5-years-old boy who presented with right lower quadrant abdominal pain. His clinical signs, symptoms and investigations mimicked an acute appendicitis. Intraoperatively we found a 720° appendix torsion on its base with its mesentery rotated in counter-clockwise direction. The appendix was gangrenous in appearance. A video-assisted trans-umbilical appendectomy was performed. We describe clinical presentation and management of this rare condition reviewing the literature.

Surgical management of subhepatic perforated appendicitis: a case report

Background

Subhepatic appendicitis is an exceedingly rare presentation, accounting for 0.01% of acute appendicitis cases. It is of prime importance to be aware of variants and manage such challenging cases accordingly.

Case presentation

We present a case of a middle-aged Saudi woman with subhepatic perforated appendicitis and peritonitis who underwent an exploratory laparotomy and appendectomy.

Conclusions

The initial diagnosis and surgical management of such patients is challenging due to an atypical presentation. The surgical management of such patients is discussed with a brief review of the literature.

Torsion of vermiform appendix: case report and review of the literature

Background

Torsion of the vermiform appendix is a rare disease with symptoms very similar to those of acute appendicitis. We herein report a case of torsion of the vermiform appendix diagnosed by intraoperative findings.

Case presentation

A 4-year-old boy presented to our hospital because of abdominal pain and vomiting. Laboratory data revealed a C-reactive protein level of 0.08 mg/dL and white blood cell count of 19,300/μL (neutrophils, 88.9%). Abdominal ultrasound showed a target sign-like finding in the ileocecal region. A computed tomography scan showed swelling of the appendix. We performed an emergency operation under suspicion of acute appendicitis. Laparoscopic examination showed that the appendix had twisted 720° in the clockwise direction. Appendectomy was performed, and the postoperative course was uneventful.

Conclusions

Although torsion of the vermiform appendix is a very rare disease and difficult to differentiate from appendicitis, an inappropriate treatment plan could lead to necrosis and perforation of the appendix. It is important to consider this disease as a differential diagnosis in patients with right lower abdominal pain.

A rare case of perforated "sub-hepatic appendicitis" - a challenging differential diagnosis of acute abdomen based on the combination of appendicitis and maldescent of the caecum

Unusual locations of the appendix vermiformis can result in delay in appropriate diagnosis and treatment of appendicitis. So an inflamed appendix in a sub-hepatic caecum caused by caecal maldescent for example can mimic cholecystitis, the pain being localized in the right upper quadrant. Here, we present a case of perforated sub-hepatic appendicitis with peritonitis, requiring open ileocaecal resection. Review of the existing literature has demonstrated that this pathology is uncommon, yet not so rare as one might presume. In conclusion, surgeons should be aware of this possibility in the diagnostic and therapeutic management of acute abdomen.

Subhepatic appendicitis: a diagnostic dilemma

A middle-aged woman was admitted with recurrent episodes of ill-defined right-sided abdominal pain, more prominent in the right upper quadrant. Surgical history revealed a laparoscopic cholecystectomy, 1 month prior, for gallstones that were thought to be the cause of her symptoms. However, she continued to experience similar pain with exacerbation leading to readmission. Blood tests revealed increased inflammatory markers and an ultrasound scan showed a tubular hypoechoic structure between her right kidney and liver corresponding to the area of maximal tenderness. A diagnostic laparoscopy was performed and a subhepatic inflammatory mass of appendicular origin was found. This required mobilisation of the right colon and appendicectomy. The patient made an uneventful recovery after being readmitted for an ileus treated conservatively. Histology revealed acute appendicitis with mucosal ulceration.

Rare case of an abdominal mass presenting as acute abdomen: torsion of the vermiform appendix

Torsion of the vermiform appendix is a rarely observed acute abdominal emergency. The clinical manifestations are similar to acute appendicitis. It should be included in the differential diagnosis if a patient presents with intermittent abdominal pain and an acute abdominal emergency. Here, we describe a 4-year-old male patient with a mass located in the right lower abdominal quadrant, whose clinical findings were consistent with an acute abdomen. The gangrenous appendix was found in the pelvic cavity and its stump was twisted clockwise. A 1.5-cm fecalith was detected in the appendix lumen and appendectomy was performed.

Appendiceal torsion associated with undescended caecum: a case report and review of the literature

Torsion of the vermiform appendix is a rare disorder that causes symptoms similar to those of acute appendicitis. Primary and secondary causes of appendiceal torsion have been reported in the literature. Laparoscopy appears to be the most appropriate modality for diagnosis and treatment where the condition is suspected. To our knowledge this is the first case of appendiceal torsion in an adult causing right upper quadrant pain related to caecal malposition.
