Background: Endometriosis is a benign estrogen-dependent gynecological disease involving components of the female genital tract (uterus, Fallopian tubes, ovaries, large, round, and utero-sacral ligaments) and intra- and extraperitoneal regions. Since the moment of its etiopathogeny has been identified, the intrinsic capacity of endometriosis malignant transformation has been hypothesized.

Patients, Materials And Methods: Our study included a total number of 50 patients diagnosed with endometriosis (31 cases) and endometriosis-related ovarian carcinoma (EOC) (19 cases). Read More

Department of Surgery, Kurume University Hospital, Kurume, Japan.

Background: Intrahepatic cholangiocarcinoma (ICC) is primary cancer of the liver with poor prognosis because of its high potential for recurrence and metastasis. We experienced a rare case of ICC with hematogenous metastasis to the falciform ligament. We aimed to clarify the route of metastasis to the mesentery by increasing the accuracy of preoperative imaging and establish a hepatectomy to control cancer. Read More

Background: Magnetic resonance imaging (MRI) can show the architecture of the hip joint clearly and has been increasingly used in developmental dysplasia of the hip (DDH) confirmation and follow-up. In this study, MRI was used to observe changes in the hip joints before and after closed reduction (CR) and to explore risk factors of residual acetabular dysplasia (RAD).

Case: Seven years after hip arthroscopy for cam impingement, a 47-year-old female patient suffered a valgus impacted femoral neck fracture of her left hip that was stabilized with cannulated screws. After fracture healing, she experienced persisting sharp groin pain that could be elicited in flexion/internal rotation and extension/adduction. We suspected a ligamentum teres impingement at the border of the acetabular fossa due to a post-traumatic fovea alta and performed an arthroscopic ligament resection. Read More

Background: Measuring the strain patterns of ligaments at various joint positions informs our understanding of their function. However, few studies have examined the biomechanical properties of ankle ligaments; further, the tensile properties of each ligament, during motion, have not been described. This limitation exists because current biomechanical sensors are too big to insert within the ankle. Read More

Purpose: In the classical description of normal liver anatomy, the umbilical fissure is a long, narrow groove that receives the ligamentum teres hepatis. The pons hepatis is an anatomic variant, where the umbilical fissure is converted into a tunnel by an overlying bridge of liver parenchyma. We carried out a study to evaluate the existing variations of the umbilical fissure in a Caribbean population. Read More

As our understanding of hip function and disease improves, it is evident that the acetabular fossa has received little attention, despite it comprising over half of the acetabulum's surface area and showing the first signs of degeneration. The fossa's function is expected to be more than augmenting static stability with the ligamentum teres and being a templating landmark in arthroplasty. Indeed, the fossa, which is almost mature at 16 weeks of intrauterine development, plays a key role in hip development, enabling its nutrition through vascularization and synovial fluid, as well as the influx of chondrogenic stem/progenitor cells that build articular cartilage.

The left-sided gallbladder (LSG) is a rare type of anatomical variation (ectopia) defined by the location of the bladder to the left side of the liver falciform and round ligaments. Initially reported in 1886 by Hochstetter, the finding is usually accidental since it is mostly an asymptomatic condition, thus not causing the patient any harm and being few reported cases in the current literature. Surgical cases are most associated with gallstones such as presented in this case report. Read More

Background: Laparoscopic pancreaticoduodenectomy (LPD) technique with artificial vascular graft reconstruction for patients with borderline resectable pancreatic cancer has been rarely reported since it is a very challenging technique. However, preliminary experience for the technique has been reported at the Department of Pancreatic Surgery, West China Hospital, Sichuan University.1,2 The rising popularity of neoadjuvant chemotherapy for pancreatic cancer patients may result in the increase of operative difficulty due to tissue edema and many other factors caused by the chemotherapy.

J Minim Invasive Gynecol 2020 Oct 5. Epub 2020 Oct 5.

Department of Surgical Oncology, ICM - Val d'Aurelle - Montpellier, France.

Study Objective: Minimally invasive surgery (MIS) decreases postoperative morbidity after radical hysterectomy (RH) for early-stage cervical cancer. However, a randomized trial and large retrospective data question its safety after observing lower rates of survival than open surgery [1,2]. The causes of this higher recurrence rate are not definitely established but may result from cancer exposure to peritoneum during vaginal section and cancerous-cells spillage enhanced by pneumoperitoneum or uterine manipulator.
