Background: The operative treatment of post-traumatic neuromas includes open exploration, excision of adhesions and/or neurectomy. Apart from the anatomical variations of the peripheral nerves and their branches’ routes, nerves may be further deviated from their expected anatomical locations due to scar tissue formation. We describe a simple and reproducible method of preoperative skin marking which aids the development of an accurate surgical exposure for the localisation of a lesion. Method: Skin marking is based on clinical assessment and is performed by the bedside on the day of the operation. It consists of mapping the skin with permanent marker by repeatedly using three symbols, namely √, O or X. These refer respectively to areas of normal sensation, numbness (decreased or no sensation without paraesthesia) and pain/dysaesthesia. Points with a positive Tinel sign were marked with an “X in a square”. Fourteen patients, aged 21–55 years old, with post-traumatic neuromas, were marked with the method. A total of 18 neuromas were successfully located in the upper and lower limbs. Results: In all cases the preoperative skin marking corresponded to the course of the nerve and/or its branches. All patients were improved with a good to excellent clinical outcome. Conclusions: Planning the surgical approach according to the skin marking enabled limited operative exposures and corresponded to atypical locations and branching of the peripheral nerves. © 2015, Springer-Verlag Wien.

Intestinal obstruction in pregnancy is not common. Colonic volvulus occurs in 24% of such cases. Due to the rare incidence and lack of imaging during pregnancy, correct diagnosis is often delayed. We present a case of a 33-year-old female with a twin pregnancy gestation, who presented with acute abdominal pain. Physical examination revealed a gravid uterus and tenderness in the lower abdominal quadrants. Due to intense uterine contractions, the patient was urgently submitted to cesarean delivery, giving birth to two healthy infants. Twelve hours after the cesarean section, right lower quadrant abdominal pain was persistently severe. Nausea, vomiting, diarrhea, and abdominal dilatation were also present. Abdominal X-ray and CT scan showed bowel obstruction, possibly secondary to cecal volvulus. The patient was subjected to explorative laparoscopy, cecal volvulus detorsion, and laparoscopic appendectomy. The postoperative course was uneventful, and the patient was discharged on the fourth postoperative day. Cecal volvulus in pregnancy is a rare, difficult to diagnose, clinical entity. It is associated with high morbidity and mortality, both of mother and fetus, because of delayed diagnosis. A high index of clinical suspicion is required in pregnant or puerperant women with signs and symptoms of bowel obstruction and persistent pain at the right low abdominal quadrant. As long as diagnosis is timely set, laparoscopy is a safe and successful means of surgical treatment. Source

Early rectal cancer (ERC) is adenocarcinoma that has invaded into, but not extended beyond, the submucosa. Endoscopic or minimal access surgical procedures, such as laparoscopic resection, have emerged as a useful tool in the surgical treatment of such diseases. The aim of this study is to present and analyze the feasibility, the short- and long-term results of laparoscopic colorectal surgery (LCS) in patients with ERC. Between 2002 and 4/2011, a total of 164 patients with colorectal cancer underwent laparoscopic surgery (LS). Of these, 7 patients (4.2%) had ERC and underwent laparoscopic anterior resection (LAR). The median follow-up was 41 months. The mean operative time was 2.5 h. None of the laparoscopic procedures was converted to open surgery. Liquids and solid food were started on median postoperative days 1 and 3, respectively. The median length of postoperative stay was 5 days. Postoperative complications occurred in 2 patients (28.5%), including wound infection in one patient (14.2%) and atelectasis in one patient (14.2%). None of the patients required an urgent re-operation. There was no mortality related to LS. LS for ERC can be used as a strategy sited between endoscopic mucosal resection and open anterior resection with beneficial long- and short-term results. It appears as a technically and oncologically safe procedure when performed by surgeons with sufficient experience in laparoscopic techniques. Source

Stroke is a major contributor to population morbidity and mortality. Cardiac thromboembolic sources are an important potential cause of stroke. Left atrial appendage (LAA) thromboembolism in association with atrial fibrillation is a major contributor to stroke occurrence, particularly in elderly individuals. Patent foramen ovale (PFO) acts as a potential conduit from the right-sided circulation to the brain, and has been suggested to be an important factor in cryptogenic stroke in the young patients. Advances in interventional cardiology have made it possible to deal with these potential stroke sources (LAA and PFO), but the available methods have intrinsic limitations that must be recognized. Furthermore, the potential value of LAA and PFO closure depends on our ability to identify when the target structure is importantly involved in stroke risk; this is particularly challenging for PFO. This article addresses the clinical use of PFO and LAA closure in stroke prevention. We discuss technical aspects of closure devices and methods, questions of patient selection, and clinical trials evidence. We conclude that for PFO closure, the clinical trials evidence is thus far negative in the broad cryptogenic stroke population, but closure might nevertheless be indicated for selected high-risk patients. LAA closure has an acceptable balance between safety and efficacy for atrial fibrillation patients with high stroke risk and important contraindications to oral anticoagulation. Much more work needs to be done to optimize the devices and techniques, and better define patient selection for these potentially valuable procedures. © 2014 Canadian Cardiovascular Society. Source

Methods ICE-guided percutaneous LAA closure was performed in 121 patients to evaluate the following tasks typically achieved by TEE: assessment of the LAA dimension for device sizing; guidance of transseptal puncture; verification of the delivery sheath position; confirmation of location and stability of the device before and after release and continuous monitoring to detect procedural complications. In 51 consecutive patients, we compared the measurements obtained by ICE and fluoroscopy to choose the size of the device.Results The device was successfully implanted in 117 patients, yielding a technical success rate of 96.7%. Procedural success was achieved in 113 cases (93.4%). Four major adverse events (3 cardiac tamponades and 1 in-hospital transient ischemic attack) occurred. There was significant correlation in the measurements for device sizing assessed by angiography and ICE (r = 0.94, p < 0.0001).Conclusions ICE imaging was able to perform the tasks typically provided by TEE during implantation of the Amplatzer Cardiac Plug device for LAA occlusion. Therefore, we provide evidence that the use of ICE offered accurate measurements of LAA dimension in order to select the correct device sizes.Objectives This dual-center study sought to demonstrate the utility and safety of intracardiac echocardiography (ICE) in providing adequate imaging guidance as an alternative to transesophageal echocardiography (TEE) during Amplatzer Cardiac Plug device implantation.Background Over 90% of intracardiac thrombi in atrial fibrillation originate from the left atrial appendage (LAA). Patients with contraindications to anticoagulation are potential candidates for LAA percutaneous occlusion. TEE is typically used to guide implantation. © 2014 American College of Cardiology Foundation. Source
