Objective: To compare the operation time and performance of two uterine manipulators used for total laparoscopic hysterectomy (TLH).
Material and methods:Design: Retrospective cohort analysis. Design classification: Canadian Task Force Classification II-2. Setting: Tertiary-care university-based teaching hospital and academic affiliated private hospital. Patients: All consecutive patients who underwent for TLH between January 2014 and June 2017. All operations were performed by two expert endoscopic surgeons using one of the following uterine manipulators depending on surgeon preferences: Clermont-Ferrand (CF) or Vectec (VT) MAUT60. Patients were excluded if additional surgeries such as urogynecological procedures were performed, TLH was converted to laparotomy prior to colpotomy, and when their operation records could not be obtained. A total of 169 patients were added to final analysis. Operation time, colpotomy time and the subjective performance of manipulators such as movement of the uterus, visualization of the vaginal fornices, and maintenance of pneumoperitoneum were evaluated by watching un-edited operation videos.
Results: A total of 169 patients (83 patients in CF group; 86 patients in VT group) were included in the final analysis. Patients’ baseline characteristics were comparable between groups. Operation time and time required for colpotomy were significantly shorter in the VT group. Lateral movements of the manipulators and elevation of the uterus were better with VT compared to CF (p?=?.001 for both). Compared to the CF, VT was superior for visualization of the vaginal fornices (p?=?.004) and maintenance of pneumoperitoneum (p?<?.001). Both surgeons had perfect agreement on the performance grading of manipulators (p?<?.001, Kappa values were between 0.86–0.92). There was no difference between groups in estimated blood loss and duration of hospital stay. Reinsertion or the need to change the manipulator was not required in either group. No pelvic or vaginal abscess, cuff cellulitis, dehiscence, or hematoma formations were noted.
Conclusion: Laparoscopic hysterectomy assisted with the VT uterine manipulator is associated with shorter operation and colpotomy time. Furthermore, the movements of uterus, visualization of the vaginal fornices, and maintenance of pneumoperitoneum were significantly better with VT compared to the CF manipulator. 相似文献
The new measures implemented in hospitals also altered the operation of orthopedics and traumatology departments. The main purpose of this article is to discuss how orthopedic oncology clinics should be organized during the pandemic and to present the process management scheme for patients requiring orthopedic surgery, including trauma surgery, from diagnosis to treatment, together with our experiences. Instead of thinking about the global emergence of the epidemic, it is time to act decisively. At first glance, the coronavirus disease 2019 (COVID-19) pandemic and orthopedics may seem to be unrelated disciplines, but the provision of healthcare services to patients who require them proves that these two fields are parts of the same whole. Our experiences in treating neutropenic, lymphocytopenic, and chemotherapy patients seem to have proven beneficial during this process. We operated on 10 biopsy patients, 15 primary bone sarcomas, 9 soft tissue sarcomas, and 82 trauma patients within this time frame. Only three patients were suspected to have COVID-19 before admission. The early identification, strict isolation, and effective treatment of these patients prevented any nosocomial infections and disease-related comorbidities. This success is the result of the multidisciplinary cooperation of the Ministry of Health, our hospital, and our clinic. 相似文献
Hydatid cyst disease, which is endemically observed and an important health problem in our country, involves the spleen at a frequency ranking third following the liver and the lungs. In this study, we aimed to evaluate the efficacy and results of management in splenic hydatid cysts. The demographic data, localization, diagnosis, treatment methods, and the length of postoperative hospital stay of patients with splenic hydatid cysts in a 12-year period were evaluated retrospectively. Seventeen cases were evaluated. Among these, 13 were females and four were males. Seven had solitary splenic involvement, eight had involvement of both the spleen and the liver, and two had multiple organ involvement. Ten had undergone splenectomy, one had undergone distal splenectomy, and the remaining cases had undergone different surgical procedures. The patients had received albendazole treatment in the pre- and postoperative period. One patient had died secondary to hypernatremia on the first postoperative day. The clinical picture in splenic hydatid cysts, which is seen rarely, is usually asymptomatic. The diagnosis is established by ultrasonography and abdominal CT. Although splenectomy is the standard mode of treatment, spleen-preserving methods may be used. 相似文献
Myocardial hypertrophy and cardiac dysfunction frequently occur in newborns of diabetic mothers. The authors hypothesized that wall hypertrophy or disproportionate left ventricular wall thickness in newborns of diabetic mothers may affect both QT and QTc dispersion. This study aimed to assess whether left ventricular hypertrophy affects the QT variables of infants born to diabetic mothers. This prospective cross-sectional study was conducted with 47 consecutively selected neonates of gestational diabetic mothers and 30 healthy neonates born to healthy mothers. All the subjects were evaluated during the neonatal period. Electrocardiography with echocardiography was performed for the patients and the control subjects. The newborns of the diabetic mothers were classified according to septal thickness as group 1 (16 newborns with septal hypertrophy) or group 2 (31 newborns without septal hypertrophy). The study group consisted of three cohorts: groups 1, 2, and 3 (control group). Both QT and QTc dispersion were computed from a randomly selected beat as well as from an average beat derived from 12 beats included in a 10-s electrocardiography. A total of 16 infants (34 %) had a septal thickness of 6 mm or greater. The left ventricular end-systolic diameter in group 1 was smaller (p = 0.0029) than in groups 2 and 3 (p = 0.003). The interventricular septal thickness at end diastole (IVSTd) and the left ventricular posterior wall thickness at end diastole in group 1 were higher than in of groups 2 and 3. The QT and QTc dispersion intervals were longer in group 1 than in groups 2 and 3 (p < 0.001), and a highly significant positive correlation was detected between IVSTd and QT dispersion (r = 0.514, p = 0.042). Elevated QT and QTc dispersions may be risk factors for the development of arrhythmias in newborns of diabetic mothers. These patients may critically need systematic cardiac screening. 相似文献
STATEMENT OF PROBLEM: A newly introduced high-powered light-emitting diode (LED) light-polymerization unit with various polymerization modes is purported to polymerize dental resins more quickly than standard units. However, there is insufficient information about the effects of this type of light source and its polymerization modes on resin luting agents (RLAs). PURPOSE: This in vitro study evaluated the effects of different modes of a high-powered LED polymerization unit on the shear bond strength of a light-polymerized RLA to ceramic and dentin. MATERIAL AND METHODS: Sixty ceramic cylinders (3 x 3 mm) were fabricated from a heat-pressed ceramic (IPS Empress 2). Specimen surfaces were abraded using 600-grit silicon carbide paper and airborne-particle abraded with 50-mum desiccant alumina particles, cleaned ultrasonically, etched using hydrofluoric acid, and treated with a silane coupling agent (Ceramic primer). Sixty noncarious, freshly extracted, permanent human molar teeth were embedded in autopolymerizing acrylic resin, and their dentin surfaces were wet-ground using a grinding and polishing machine fitted with 180-grit abrasive disks. The ground dentin surfaces were then etched with 37% phosphoric acid gel, and an adhesive agent (Single Bond) was applied. Ceramic specimens (n = 15) were bonded to dentin surfaces with a dual-initiated RLA (Rely-X ARC) and individually polymerized by 1 of 4 different modes, as follows: Halogen standard mode (Control) (600 mW/cm2 for 40 seconds); high-powered LED fast mode (1100 mW/cm2 for 10 seconds); high-powered LED pulse mode (1100 mW/cm2 for 10 seconds); and high-powered LED exponential mode (1100 mW/cm2 for 20 seconds). Cemented specimens were subjected to shear loading until fracture using a universal testing machine. A stereomicroscope (x25) was used to identify the mode of fracture. Bond strength (MPa) data were analyzed using 1-way analysis of variance and the Tukey HSD test (alpha = .05). RESULTS: Specimens polymerized using halogen standard mode (23.9 +/- 1.3 MPa) and LED exponential mode (23.0 +/- 1.1 MPa) had significantly higher ( P < .001) mean shear bond strengths compared with both LED fast (15.1 +/- 1.3 MPa) and pulse (14.6 +/- 1.3 MPa) modes. The Tukey HSD tests showed no significant differences in shear bond strength between specimens polymerized using high-powered LED exponential mode and halogen standard mode. Most failures were adhesive failures at the dentin-RLA interface or the RLA-ceramic interface in specimens polymerized using high-powered LED fast or pulse modes. CONCLUSION: Within the limitations of this study, the shear bond strength of an RLA to ceramic and dentin was found to be similar when polymerized using halogen light in standard mode and high-powered LED light in exponential mode, whereas shear bond strength was significantly lower when polymerized using LED in fast or pulse mode. 相似文献
This study emphasizes the importance of diagnostic first aid procedures to avoid the consequences of trauma due to foreign body. A 20-year-old man referred to our hospital with a history of having a sharp penetrating injury to his right eye. Computed tomography evaluation reported right globe perforation and intraorbital glass foreign body measuring 4 x 7 cm was removed. Perforated eye was repaired and traumatic cuts were sutured. Orbital and ocular injuries are common, and delays in management may lead to complication. A team approach is the best technique for these patients. 相似文献
