Filter by:The involvement of the inferior vena cava (IVC) in advanced abdominal tumors is a surgical challenge, given the high postoperative morbidity and poor long-term prognosis. The goal was to analyze the experience, perioperative management, and results. Investigators have evaluated short and long-term results of surgical resections of tumors with associated inferior vena cava resection performed between 2012 and 2018.
Lower partial duodenectomy could be indicated in case of injury, wide neck diverticulum, tumor invasion by other tumors such as retroperitoneal sarcoma and primary tumor of 3rd and 4th portion of the duodenum. Reconstruction after resection is usually performed by a end-to-end or end-to-side anastomosis. The investigators analyze the short and long-term results of a case series with resection for various lesions in the third and fourth duodenal portions and reconstruction of the intestinal transit through side-to-side duodenojejunostomy
Nipple-sparing mastectomy (NSM) with immediate reconstruction is one of the standard of care surgical treatments of breast cancer (BC) and is used for risk reduction in patients with a high risk for BC. While this method shows satisfactory oncologic and good cosmetic outcomes, its drawbacks include compromise of the skin flap vascularization due to skin incision, nipple-areolar complex (NAC) malposition/distortion and visible scar on the breast. NSM also has technical challenges of dissecting and removing larger specimens through limited incisions and concerns regarding oncologic effectiveness due to difficulties in visualizing regions of the breast remote from the incision. To improve cosmetic outcomes after NSM, a modification of this technique using a surgical robotic system was recently described. In a limited number of studies, the robotic NSM (RNSM) with immediate prosthetic breast reconstruction (IPBR) was shown to be feasible and safe, as well as led to excellent cosmetic outcomes and patient satisfaction. There are limited number of centers in North America and none in Canada that offer RNSM-IPBR. The investigators hypothesize that RNSM-IPBR is a feasible and safe technique that can be utilized in our institution and that it can provide superior cosmetic outcomes with less morbidity and higher patient satisfaction compared to the traditional NSM-IPBR. The aim is to conduct a single-arm prospective study to investigate the safety and feasibility, as well as cosmetic, surgical complication and patient satisfaction parameters of NSM-IPBR performed in the University Health Network (UHN). This study will serve a foundation for potential introduction of a novel surgical approach in our institution and will make it available for treatment and prevention of breast cancer in Canadian women. The study will also serve as pilot data for future potential studies, including randomized-controlled trials (RCT) comparing RNSM with conventional NSM. As such, the study will further our approach to innovation in breast surgical oncology within Canada and North America.
The purpose of this small randomized pilot study is to evaluate adherence to strict transfusion protocols in both the control and ANH group examining compliant and noncompliant transfusion rates and reasons for violation of the protocol if present. Data on transfusion requirements for both groups (with and without ANH) will be evaluated to determine sample size and feasibility of performing a larger study on ANH in our patient population. The ultimate purpose of a larger study would be to determine if acute normovolemic hemodilution results in a reduction in red blood cell units transfused in patients undergoing cardiac surgery involving cardiopulmonary bypass (CPB) and to carefully determine provider adherence to specific transfusion triggers for the administration of each unit of harvested and banked blood transfused. Secondary endpoints that will be evaluated in a larger study include any difference in the number of other blood products transfused including fresh frozen plasma, platelets, and cryoprecipitate as well as differences in coagulation status as measured by thromboelastography (TEG), INR/PTT, platelet count, and fibrinogen level, and ICU/hospital length of stay.
Muscle relaxants are routinely applied during anesthesia to facilitate endotracheal intubation and to improve surgical working conditions. Several investigations have shown that a deep neuromuscular block (NMB) improves the surgical working conditions over a moderate NMB and effectively precludes sudden deterioration of the surgical field. However, whether the improvement of surgical working conditions translates into less intra- and postoperative complications remains uncertain. Small prospective or retrospective studies shown an decrease of the incidence of intraoperative adverse events and postoperative complications after a deep NMB. There is a need to confirm these outcome data prospectively, in a large number of patients and clinics and during a variety of surgical procedures.

Robotic mastectomy with immediate reconstruction was introduced by Toesca et al. in 2015. Since then, several studies have reported the safety and feasibility of robotic nipple-sparing mastectomy with immediate reconstruction. However, most studies were conducted by single centers and had small samples. Furthermore, there is a lack of studies comparing surgical and oncologic outcomes between robotic nipple-sparing mastectomy and conventional nipple-sparing mastectomy. For this reason, this study evaluates surgical and oncologic outcomes of robotic nipple-sparing mastectomy with immediate reconstruction using international multi-center data.

Purpose The primary purpose of the current project is to characterize unselected patients undergoing surgery developing post-operative atrial fibrillation (POAF), ultimately leading to a new risk-stratification model. Background and rationale According to rather scarce existing reports, it is estimated that 10% will develop POAF following abdominal surgery. It remains a challenge for the clinicians to predict which patients are at risk. POAF can be difficult to diagnose, as symptoms are often vague. Hence, the diagnosis may remain underreported leaving many patients without adequate treatment. Untreated atrial fibrillation is associated with increased morbidity and mortality, especially due to an increased risk of ischemic stroke. Methods Three-hundred adult patients admitted for surgery at the Digestive Disease Center at Bispebjerg Hospital will be examined by heart rhythm monitoring during hospitalization, i.e. pre-, peri- and postoperatively in the main SECAFIB-SURG study. Twenty study participants who develop POAF and 20 without POAF matched with these on sex, age and co-morbidity, will undergo additional cardiovascular examinations three months after surgery in the current sub-study. All patients will be followed for at least one year after surgery. The study is scheduled for completion within two years, commencing in January 2020. Perspective Creating a POAF risk-stratification model for patients undergoing abdominal surgery, could ensure timely diagnosis and treatment, hence, preventing complications associated with POAF.
Background and purpose Post-operative AF (POAF) is considered a phenomenon rather than a definite diagnosis and the current clinical guidelines have no specific recommendations regarding its management. Few prospective studies have been performed in non-cardiac conditions and the consequences of POAF in patients without known heart disease are not well described. However, recent data suggest an association between POAF in relation to non-cardiac surgery and increased post-operative mortality and stroke. POAF in relation to abdominal surgery seems common (incidence: 8-18%); however, the true incidence is uncertain. The available studies are few, heterogeneous, and often methodologically inadequate. The study aims at reporting the incidence of atrial fibrillation (AF), and associated complications, in relation to abdominal surgery. Material and methods Designed as a prospective, single-centre, cohort study of consecutive adult patients undergoing acute* abdominal surgery at the Department of Abdominal Surgery at Bispebjerg Hospital. Patients who are pregnant or where follow-up is not possible will be excluded. Patients will be examined pre-operatively by ECG and signal processed surface ECG (wavECG). A subset of patients admitted to the Department in the time interval of 7 AM to 11 PM$, will be offered heart rhythm monitoring from admission and until discharge (preferably ≥72 hours post-operatively). Additional follow-up will be based on a review of patient charts at discharge and one# month postoperatively. The primary endpoint is the occurrence/recurrence of AF. The study will include 400-500 patients of which an estimated 2/3 will wear heart rhythm monitoring corresponding to 264-330 patients. Perspective If more thorough heart rhythm monitoring of patients undergoing abdominal surgery leads to the identification of more patients with AF, routine continuous heart rhythm monitoring should be considered recommended in upcoming guidelines to prevent associated complications.
