Ileus Following Spontaneous Jejunum Intramural Hematoma: Case Report and Review of the Literature

2012

Anticoagulant therapy may cause the onset of a spontaneous intramural hematoma of the small bowel, in the jejunum, ileum or duodenum. A 53-year-old woman on therapy with heparin for previous pulmonary embolism was admitted for abdominal pain and vomit. Computed tomography scan visualized an intramural hematoma of the jejunum causing subtotal obstruction of the intestinal lumen. The patient underwent resection of a part of the jejunum, securing intestinal continuity by a mechanical side-to-side anastomosis. The postoperative course was regular, but the initial anticoagulant therapy was reduced to prevent recurrence. In conclusion, spontaneous hematoma of small bowel can occur as a complicati…

Arnold Zweigs Auseinandersetzung mit der Judenfrage in seinen frühen Erzählungen. Zur schlesischen Prägung der gestalteten Erfahrungen

2017

Artykuł jest poświęcony literaturoznawczo zaniedbanemu aspektowi twórczości Arnolda Zweiga, mianowicie tym wczesnym opowiadaniom, które traktują o jego judaizmie. W pierwszej kolejności analizowane są nowele Die Flucht der van Spandows i Die Krähe. Następnie pada pytanie, jakie możliwości uchwycenia i opisu żydowskiego losu dawało śląskie pochodzenie Arnolda Zweiga.

Pre-operative interventional radiology: could it have a role before complex laparoscopic surgery?

2021

Bleedings occurring during a surgical intervention can be caused by haemostatic defects, but they are generally due to ineffective local haemostasis. Current coagulation systems may not be sufficient to achieve a good haemostasis, causing, at the same time, tissue dama-ge. Furthermore, the availability of such devices does not eliminate difficulties linked to the isolation of vessels, a crucial step of surgical procedures that require the removal of an organ or part of it, in case of inflammation or neoplasm. This difficulty is even more evident, and weighs more on operative times, when the surgeon engages with video-assisted surgery, where anatomical structures are difficult to detect and …

Segregation in Drying Binary Colloidal Droplets

2019

When a colloidal suspension droplet evaporates from a solid surface, it leaves a characteristic deposit in the contact region. These deposits are common and important for many applications in printing, coating, or washing. By the use of superamphiphobic surfaces as a substrate, the contact area can be reduced so that evaporation is almost radially symmetric. While drying, the droplets maintain a nearly perfect spherical shape. Here, we exploit this phenomenon to fabricate supraparticles from bidisperse colloidal aqueous suspensions. The supraparticles have a core-shell morphology. The outer region is predominantly occupied by small colloids, forming a close-packed crystalline structure. Tow…

The LANN technique to reduce postoperative functional morbidity in laparoscopic radical pelvic surgery

2005

BACKGROUND: We investigated the feasibility and advantages of introducing Laparoscopic Neuro-Navigation (LANN) into the field of laparoscopic gynecologic radical pelvic surgery. STUDY DESIGN: In a prospective pilot study, 261 consecutive patients underwent laparoscopic radical pelvic surgery for cervical cancer or deep infiltrating endometriosis of the parametria. During the procedure, dissection and electrostimulation, and consequently, sparing of the pelvic parasympathetic nerves by transection of the parametria, were performed. Postoperative bladder dysfunction was documented. RESULTS: Laparoscopic dissection and electrostimulation of the pelvic splanchnic nerves were feasible in all pat…

Histologic analysis of specimens from laparoscopic endometrioma excision performed by different surgeons: does the surgeon matter?

2011

Objective To evaluate whether the amount of ovarian tissue inadvertently removed along with the endometrioma cyst wall at laparoscopy differs in relation to the operating surgeon's level of expertise. Design Multicenter, prospective trial. Setting Four tertiary care university hospitals. Patient(s) Fifty patients, aged 25 to 40 years, with monolateral ovarian endometriomas who underwent laparoscopic excision. Intervention(s) Operation with the stripping technique by surgeons with specific expertise in endometriosis surgery in four centers (groups A, B, C, and D) and by residents with average training in laparoscopic surgery (group E). Main Outcome Measure(s) Histologic examination for the e…

Colorectal infiltrating deep endometriosis: Laparoscopic treatment. A case report

2022

Endometriosis is a disease affecting approximately 10% of women of fertile age. A particular presentation is deep infiltrating endometriosis of the rectosigmoid colon with symptoms that can mimic an intestinal obstruction or neoplasm. We report the case of a 39-year-old woman with pelvic pain during the menstrual cycle and significant anemia who presented an ectopic endometrial tissue in correspondence of the rectum. Because of the thickness of the lesion the patient underwent a segmental laparoscopic colorectal resection with end-to-end anastomosis.

Finite element analysis of a Bionate ring-shaped customized lumbar disc nucleus prosthesis

2021

[EN] Study design: Biomechanical study of a nucleus replacement with a finite element model. Objective: To validate a Bionate 80A ring-shaped nucleus replacement. Methods: The ANSYS lumbar spine model made from lumbar spine X-rays and magnetic resonance images obtained from cadaveric spine specimens were used. All materials were assumed homogeneous, isotropic, and linearly elastic. We studied three options: intact spine, nucleotomy, and nucleus implant. Two loading conditions were evaluated at L-3-L-4, L-4-L-5, and L-5-S-1 discs: a 1000 N axial compression load and this load after the addition of 8 Nm flexion moment in the sagittal plane plus 8 Nm axial rotation torque. Results: Maximum nuc…

Tratamiento quirúrgico de la enfermedad por reflujo gastroesofágico. Valoración de resultados y estado actual de las indicaciones

2015

1. PLANTEAMIENTO DEL PROBLEMA La Enfermedad por Reflujo Gastro-Esofágico (ERGE) constituye una entidad de elevada prevalencia en la población general (7’7 %). Su tratamiento desde que Nissen realizara en 1956 la primera funduplicatura, ha sufrido muchos vaivenes, debido a la aparición de fármacos antisecretores cada vez de mayor potencia, a los efectos inherentes de la cirugía (disfagia, atrapamiento aereo, imposibilidad de eructar / vomitar), y a la aparición de la funduplicatura laparoscópica (Dallemagne 1992) que supuso un cambio explosivo a favor del tratamiento quirúrgico. No obstante, a partir de 2005, tras una década de funduplicatura laparoscópica, y tras millares de enfermos interv…
