Pain Mechanisms in Peritoneal Diseases Might Be Partially Regulated by Estrogen
2017
To identify factors influencing the differential pain pathogenesis in peritoneal endometriosis (pEM) and peritoneal carcinomatosis in ovarian cancer (pOC), we undertook an experimental study. Tissue samples of 18 patients with pEM, 15 patients with pOC, and 15 unaffected peritoneums as controls were collected during laparoscopy or laparotomy. Immunohistochemical stainings were conducted to identify nerve fibers and neurotrophins in the tissue samples. Additionally, 23 pEM fluids, 25 pOC ascites fluids, and 20 peritoneal fluids of patients with myoma uteri as controls were collected. In these fluids, the expression of neurotrophins was evaluated. The effects of peritoneal fluids and ascites …
Vena cava resection and bypass for recurrent cervical cancer
2021
A 42-year-old woman was diagnosed with a second para-aortic cervical cancer. The patient had undergone a radical hysterectomy with pelvic lymphadenectomy for FIGO stage IB1 squamous cervical cancer 3 years prior to current presentation. No adjuvant treatment was performed after the primary surgery
Peritoneal sarcomatosis 5 years after laparoscopic morcellation of uterine leiomyoma.
2017
In 2011, a 40-year-old woman underwent laparoscopic myomectomy with intraabdominal morcellation. Histology report showed leiomyoma without atypia, necrosis, or mitosis. In 2016, she complained of left lower quadrant pain; ultrasound examination revealed a left hypogastric mass in the site of trocar placement. Percutaneous biopsy results showed a low-grade endometrial stromal sarcoma (LGESS). At laparoscopy, we observed: multiple nodules on uterine serosa, left annex, vesical peritoneum (Figure 1), Douglas pouch (Supplementary Video1), previous left pelvic trocar site (Figure 2), greater omentum (Figure 3), and right/left diaphragm.
CT and MR Imaging of Retroperitoneal Sarcomas: A Practical Guide for the Radiologist
2023
Primary retroperitoneal sarcomas (RPS) represent around 10–16% of all sarcomas, with liposarcomas and leiomyosarcomas being the most common subtypes. RPS have some peculiar characteristics, imaging appearances, worse prognosis, and complications compared to other locations of sarcoma. Commonly, RPS primarily present as large masses, progressively encasing adjacent structures, causing mass effect, and complications. RPS diagnosis is often challenging, and these tumors may be overlooked; however, failure to recognize RPS characteristics leads to a worse prognosis for the patients. Surgery is the only recognized curative treatment, but the anatomical constraints of the retroperitoneum limit th…
The prognostic value of skeletal muscle index on clinical and survival outcomes after cytoreduction and HIPEC for peritoneal metastases from colorect…
2021
BACKGROUND Cytoreductive surgery (CRS) and hypertermic intraperitoneal chemotherapy (HIPEC) represent the most effective strategy to manage peritoneal metastases (PM). This systematic review and meta-analysis aimed to assess the impact of body composition on clinical outcomes in patients with PM. METHODS A systematic literature search was performed using Medline, Web of Science and EMBASE databases from inception to the 20st August 2020. Data were independently extracted by 3 authors. Newcastle-Ottawa Scale was used to assess quality and risk of bias of studies. Pooled analyses were performed using Mantel-Haenszel method to estimate overall effect size with mean differences or odd ratios (O…
Cirugía de tumores retroperitoneales con afectación de vena cava: revisión de 18 casos
2018
Resumen Introducción El tumor retroperitoneal con extensión a la vena cava inferior (VCI) más frecuente es el carcinoma de células renales. Tiene una supervivencia a 5 años de hasta un 32% cuando se realiza nefrectomía radical y trombectomía. El tratamiento quirúrgico es complejo y puede necesitar el soporte de circulación extracorpórea y parada circulatoria e hipotermia. Métodos Estudio descriptivo, retrospectivo, mediante análisis de datos de pacientes intervenidos de tumores con invasión de la VCI entre 1992 y 2015. Se recogieron datos demográficos, tumorales, de técnica quirúrgica, intraoperatorios, posquirúrgicos y de mortalidad. Las variables cuantitativas se presentan como media±desv…
Primary omental tumor with ultrastructural features of cellular schwannoma and absence of S-100 antigen reactivity.
1989
Summary We report a primary well-delimited, large mesenchymal omental neoplasm which appeared in a 58 year old man without neurofibromatous traces. The histological and ultrastructural features were consistent with a Schwann cell origin. However, repeated immunohistochemical reactions failed to demonstrate protein S-100 antigen reactivity in the neoplasic cells, the latter only expressing vimentin. The differential diagnosis with hemangiopericytoma is proposed.
Using A Heating Cable Within The Abdomen To Make Hyperthermic Intraperitoneal Chemotherapy Easier: Feasibility And Safety Study In The Swine
2009
International audience; BACKGROUND: Hyperthermic intraperitoneal chemotherapy (HIPEC) is a complex, expensive and time-consuming procedure. Despite its good results in the treatment of peritoneal carcinomatosis, these factors have precluded the wider use of this procedure around the world. We hypothesized that HIPEC could be performed by heating the liquid within the abdomen and thus avoiding the need for an external heating circuit and a pump. The aim of this study was to assess the feasibility and safety of an internal heating device for hyperthermic intraperitoneal chemotherapy in an experimental model. METHODS: Four large-white pigs underwent one-hour open intraperitoneal hyperthermia w…
Laparoscopic excision of a benign peritoneal cystic mesothelioma
2009
Benign cystic peritoneal mesothelioma is a rare tumor and most commonly occurs in women in the reproductive age group. It is very rare in women of postmenopausal age. We present a rare case of a postmenopausal woman with benign peritoneal cystic mesothelioma removed at laparoscopy.
Is the acidity of ascitic fluid a reliable index in making the presumptive diagnosis of spontaneous bacterial peritonitis?
1986
Ascitic fluid pH and arterial-ascitic fluid pH gradient were compared to ascitic fluid polymorphonuclear cell count in 84 patients with cirrhotic ascites and in 12 with malignant ascites to assess their role as diagnostic tests for spontaneous bacterial peritonitis and to clarify the relationship between ascitic fluid pH and lactate. Ascitic fluid pH was significantly lower (pH 7.30) in spontaneous bacterial peritonitis (n = 18) and probable spontaneous bacterial peritonitis (n = 12) than in sterileascites (pH 7.41; n = 54). Since blood pH levels were not different in the presence of infection, arterial-ascitic fluid pH gradient was significantly higher in spontaneous bacterial peritonitis …
