Lipoma is a common type of benign soft tissue tumor that can occur in the shoulders, neck and back, in addition to other body parts. The Retzius space is a small anatomical space between the pubic symphysis and the bladder located extraperitoneally and filled with loose fatty connective tissue. Giant lipomas are rare in the Retzius space. A 61-year-old Chinese male arrived at Beijing Yanhua Hospital (Beijing, China) due to frequent urination, and CT scan images of the lower abdomen observed a large pelvic mass and left inguinal hernia. Preoperative clinical manifestations and auxiliary examination suggested that the tumor originated from the urinary bladder wall. The maximum tumor diameter was ~25 cm and abdominal pressure was increased. Therefore, laparoscopic pelvic tumor resection combined with inguinal hernia repair was attempted. Intraoperatively, the tumor was found to originate from the Retzius space and the postoperative pathological diagnosis was lipoma. The present case report may serve as a reference for minimally invasive treatment of this type of rare disease in future.

A novel anterior approach toward robotic radical prostatectomy is associated with earlier continence recovery than the conventional approach.
Int J Urol
January 2025
Department of Urology, Jichi Medical University Saitama Medical Center, Saitama, Japan.
Article Synopsis
- A new surgical technique called the "novel anterior approach" for robotic radical prostatectomy was developed to enhance continence recovery by using a specific incision to spare surrounding blood vessels.
- A study compared this new technique in 282 patients to a traditional approach in 234 patients, finding significantly better continence recovery rates for those who underwent the novel method.
- This new approach showed promising results without negatively affecting cancer recovery rates or increasing complication risks, suggesting potential benefits that warrant further research.

Intestinal subepithelial lesions are often encountered during endoscopy. Etiologies can include lesions intrinsic or extrinsic to the gastrointestinal wall. They can present a diagnostic dilemma as simple mucosal biopsies are often nondiagnostic.

Introduction: Traditional reservoir placement (RP) into the space of Retzius during three-piece inflatable penile prosthesis implantation has been associated with serious bladder, iliac vessel, and bowel complications, encouraging the development of "ectopic" RP methods.
Objectives: In this study we sought to document an up-to-date, comprehensive analysis of ectopic RP techniques regarding both patient satisfaction and clinical complications.
Methods: A PubMed, Ovid MEDLINE, and Cochrane Library literature search of English language articles from 1966 to 2023 with keywords "inflatable," "penile prosthesis," "reservoir," and "placement" gave 179 publications, 70 of which were included in a comprehensive chronology and investigation after review.
"Fully endoscopic preperitoneal ascending suprapubic approach for minimally invasive repair of anterior and lateral abdominal wall hernias".
Hernia
October 2024
General and Digestive Surgery Department, Hospital Universitario La Paz, Universidad Autónoma de Madrid, Madrid, Spain.
Purpose: The aim of this work is to describe the rational, feasibility and clinical and Quality-of-life improvement results of a fully endoscopic preperitoneal repair for midline and lateral abdominal wall hernias, starting from the space of Retzius in a "bottom-to-up" approach.
Methods: An observational prospective data-collected and quality of life study is performed in selected patients with less than 10 cm. in diameter midline and lateral abdominal wall hernias.
Estrangulated obturatory hernia. Case report of a challenging diagnosis of obstructive syndrome.
Int J Surg Case Rep
May 2024
Anatomy and Surgery Department in Faculdade de Ciências Médicas de Minas Gerais, General Surgery at Hospital Felício Rocho, Belo Horizonte, MG, Brazil.
Introduction And Importance: Obturator hernia accounts for less than 1 % of all documented cases of pelvic hernias. It most commonly presents as an obstructive syndrome in elderly, multiparous, slim women, characterized by a wider pelvis that facilitates the passage of the hernia sac through the obturator foramen alongside the obturator nerve. In this case, adhering to the SCARE (Updating Consensus Surgical CAse REport) checklist criteria, we present a typical scenario involving an elderly woman who was initially misdiagnosed with a fecaloma, concealing an obturator hernia.
