Prognostic Factors for Surgical Failure in Malignant Bowel Obstruction and Peritoneal Carcinomatosis
2021
Introduction: Patients with peritoneal metastasis frequently develop malignant bowel obstruction (MBO). Medical palliative management is preferred but often fails. Conversely, the role of palliative surgery remains unclear and debated. This study aims to identify patients who could benefit from invasive surgical interventions and factors associated with successful surgical palliation.Materials and Methods: In this retrospective study, 98 consecutive patients who underwent palliative surgery for MBO over 5 years were reviewed. We evaluate as the primary outcome surgical failure to select patients who could benefit from palliative surgery, avoiding unnecessary surgery. A prognostic score was …
Gastrointestinal perforation: ultrasonographic diagnosis.
2013
Abstract Gastrointestinal tract perforations can occur for various causes such as peptic ulcer, inflammatory disease, blunt or penetrating trauma, iatrogenic factors, foreign body or a neoplasm that require an early recognition and, often, a surgical treatment. Ultrasonography could be useful as an initial diagnostic test to determine, in various cases the presence and, sometimes, the cause of the pneumoperitoneum. The main sonographic sign of perforation is free intraperitoneal air, resulting in an increased echogenicity of a peritoneal stripe associated with multiple reflection artifacts and characteristic comet-tail appearance. It is best detected using linear probes in the right upper q…
Innovative barriers for peritoneal adhesion prevention: liquid or solid? A rat uterine horn model.
2005
Objective To compare the effects of solid barriers (PDLA membrane and foil, Interceed), innovative barrier solutions (Adept and Hyalobarrier Gel, phospholipid emulsion), and Ringer’s lactate solution in preventing postsurgical peritoneal adhesions in the rat. Design Prospective, randomized experimental study. Setting Rat model in an academic research environment. Animal(s) Female, nonpregnant Wistar rats. Intervention(s) Standardized surgical injuries were applied to the parietal and visceral peritoneum and the uterine horns. The barrier agents were applied and the wound was closed. A second-look laparoscopy was performed 31 days after surgery to assess adhesion formation. Main Outcome Meas…
A case of splenic rupture: A rare event after laparoscopic cholecystectomy
2014
Background Laparoscopic cholecystectomy (LC) is generally safe and well-accepted. In rare cases, it is associated with complications (intra- e postoperative bleeding, visceral injury and surgical site infection). Splenic lesion has been reported only after direct trauma. We report an unusual case of splenic rupture presenting after “uncomplicated” LC. Case presentation A 77-year-old woman presented with distended abdomen, tenderness in the left upper quadrant and severe anemia 12 hours after LC. Clinical examination revealed hypovolemic shock. Abdominal computed tomography confirmed the diagnosis of splenic rupture, and the patient required an urgent splenectomy through midline incision. Th…
Imaging of Ventriculoperitoneal Shunt Complications: Comparison of Whole Body Low-Dose Computed Tomography and Radiographic Shunt Series.
2016
OBJECTIVE To determine diagnostic value and radiation exposure of low-dose computed tomography (LD-CT) compared to radiographic shunt series (SS) for the detection of ventriculoperitoneal (VP) shunt complications. METHODS Fourteen VP shunts were implanted in 7 swine cadavers. Mechanical complications were induced in 50% of VP shunts. Low-dose CT (80 kVp, 10 mAs, Pitch = 1.5) and SS were acquired. Dose area product (DAP) and effective doses for SS and LD-CT were collected. Scoring of diagnostic confidence and blinded readings of SS and CT data were performed. RESULTS The sensitivity of LD-CT was high (0.97; 95% confidence interval, 0.91-1.00) with excellent interobserver agreement (κ = 0.88)…
OneShot-M: A New Device for Close Laparoscopy Pneumoperitoneum
2018
Introduction. The induction of pneumoperitoneum is the first and most critical phase of laparoscopy, due to the significant risk of serious vascular and visceral complications. The closed technique for the creation of pneumoperitoneum could lead to several surgical complications. The present study aimed to overcome the complications associated with the insertion of Veress needle, improving its use, and facilitating the rapid creation of pneumoperitoneum. Methods. Thirty large white female pigs were enrolled in our study. A common plunger was modified in order to allow the passage of a 15-cm long Veress needle. This method was applied to 26 laparoscopic procedures (26 pigs) of several speci…

The effect of Dextransulfate 500 on the pathogenesis of herpes simplex virus infections in weanling mice
1978
Intraperitoneal (i.p.) injection of Dextran Sulfate (D.S.) 500 during a limited period of time influences the course of herpes simplex-virus-infections. D.S.500 was found to reduce the resistance of mice for some herpes simplex-virus strains (Len, L3-2s, Haase) if given between 16 hours before and 2 hours after i.p. infection. The decrease of resistance could be correlated with an increase of the virus content of liver, spleen, brain and spinal cord. Injection of herpes simplex-virus-specific immune serum counteracted the effect of D.S.500 on the course of infections. Conversely, D.S.500 increased the resistance of mice to another group of herpes simplex-viruses (strains D-316, Thea, DD), i…

Thrombotic thrombocytopenic purpura (TTP) leading to pseudotumour's autoimmune pancreatitis (AIP): A case report
2012
International audience; Introduction: Autoimmune pancreatitis is an idiopathic inflammatory disease that produces pancreatic masses and ductal strictures. This benign disease can be associated with extrapancreatic manifestations including cholangitis, sialadenitis, inflammatory bowel disease or retroperitoneal fibrosis, mediastinal adenopathy, interstitial nephritis mainly due to immunoglobulin G4 (Ig G4), and occasional association with other auto-immune diseases. Observation: We report a 57-year-old woman who developed thrombotic thrombocytopenic purpura (UP) and pseudo-tumour's seronegative autoimmune pancreatitis (ATP) type 1. The patient was initially treated with pulse corticosteroids…
