Background: Oxidized regenerated cellulose (ORC) is a bioabsorbable surgical hemostatic. We present the first prospective case series of circumscribed mass occurrence after using ORC in laparoscopic cholecystectomy.
Methods: Tabotamp (Ethicon, Inc., Somerville, NJ) in the form of tightly woven knitted patches was used to achieve hemostasis in 83 patients submitted to LC.
Results: A subhepatic mass was detected in five patients and radiologic characteristics were described. Abdominal contrast enhanced CT showed a heterogeneous soft-tissue mass. NMR was performed in one patient and showed a T2-weighted hyperintense mass.
Conclusion: ORC retention after surgery is not uncommon at long-term follow-up. The radiologic characteristics of a suspected ORC retention mass can differentiate it from a neoplastic lesion, so that surgery can be avoided.

A case report of a rare etiology of an abdominal cystic lesion in adults: Peritoneal inclusion cysts.
Int J Surg Case Rep
December 2024
Department of Visceral and Digestive Surgery, Monastir University Hospital, Monastir, Tunisia.
Introduction And Importance: Peritoneal inclusion cysts (PICs), also known as peritoneal mesothelial cysts, are rare, benign cystic lesions primarily occurring in the abdominopelvic cavity of premenopausal women with histories of pelvic surgery or inflammation. These cysts can present with nonspecific symptoms and may mimic other abdominal pathologies, making diagnosis challenging.
Case Presentation: A 41-year-old male with no significant medical history, who experienced progressive nonspecific abdominal pain over several months.
Spontaneous Hepatic Rupture Complicating Preeclampsia and HELLP Syndrome: A Case Report.

Department of Surgery, Jimma Medical Center, Jimma University, Jimma, Ethiopia.
Spontaneous hepatic rupture is a rare complication that occurs in pregnant mothers with HELLP syndrome, or preeclampsia with severe features, or eclampsia. The most common symptom of hepatic rupture/hematoma is right upper quadrant pain or epigastric pain, which is similar to the presentation of preeclampsia with severe features. Therefore, the absence of specific signs and symptoms leads to a diagnostic dilemma and a delay in management.

Background: Omental infarction is a rare pediatric disease. Ultrasound is a useful modality for a non-invasive pre-operative differential diagnosis between inflammatory conditions (as appendicitis) and omental infarction, especially by detecting immobility of the omentum adhered to the abdominal wall ("tetherd fat sign"). However, this is a dynamic sign that cannot be documented in a static image with B-mode technique.

Gossypiboma or textiloma is a rare medical situation that can complicate the favorable evolution of a surgical case, with repercussions for the patient's prognosis. The diagnosis can be difficult due to various clinical symptoms, the time elapsed since the surgical intervention, and the imaging often not being precise in detecting textilomas. Due to the medicolegal implications, the reporting of this event is inconsistent.

Article Synopsis
- Choledochal cysts (CC) are uncommon congenital conditions that can lead to complications like perforation, which occurs in 1.8-7% of cases and can be missed in infants presenting with vague abdominal symptoms.
- A 10-month-old girl was diagnosed with a spontaneously perforated CC after experiencing abdominal pain and fullness, leading to emergency drainage and successful surgical intervention.
- The case highlights the rare presentation of biliary peritonitis and the importance of recognizing CC symptoms, demonstrating that satisfactory outcomes can be achieved through a two-stage surgical approach.
