Preoperative portal vein embolization (PVE) is used to extend the indications for major hepatic resection, and it has become the standard of care for selected patients with hepatic malignancies treated at major hepatobiliary centers. To date, various techniques with different embolic materials have been used with similar results in the degree of liver hypertrophy. Regardless of the specific strategy used, both surgeons and interventional radiologists must be familiar with each other’s techniques to be able to create the optimal plan for each individual patient. Knowledge of the segmental anatomy of the liver is paramount to fully understand the liver segments that need to be embolized and resected. Understanding the portal vein anatomy and the branching variations, along with the techniques used to transect the portal vein during hepatic resection, is important because these variables can affect the PVE procedure and the eventual surgical resection. Comprehension of the advantages and disadvantages of approaches to the portal venous system and the various embolic materials used for PVE is essential to best tailor the procedures for each patient and to avoid complications. Before PVE, meticulous assessment of the portal vein branching anatomy is performed with cross-sectional imaging, and embolization strategies are developed based on the patient’s anatomy. The PVE procedure consists of several technical steps, and knowledge of these technical tips, potential complications, and how to avoid the complications in each step is of great importance for safe and successful PVE and ultimately successful hepatectomy. Because PVE is used as an adjunct to planned hepatic resection, priority must always be placed on safety, without compromising the integrity of the future liver remnant, and close collaboration between interventional radiologists and hepatobiliary surgeons is essential to achieve successful outcomes.

Major spine surgery is associated with significant blood loss, which has numerous complications. Blood loss is therefore an important concern when undertaking any major spine surgery. Blood loss can be addressed by reducing intraoperative blood loss and replenishing perioperative blood loss. Reducing intraoperative blood loss helps maintain hemodynamic equilibrium and provides a clearer operative field during surgery. Homologous blood transfusion is still the mainstay for replenishing blood loss in major spine surgery across the world, despite its known adverse effects. These significant adverse effects can be seen in up to 20% of patients. Autologous blood transfusion avoids the risks associated with homologous blood transfusion and has been shown to be cost-effective. This article reviews the different methods of autologous transfusion and focuses on the use of intraoperative cell salvage in major spine surgery. Autologous blood transfusion is a proven alternative to homologous transfusion in major spine surgery, avoiding most, if not all of these adverse effects. However, autologous blood transfusion rates in major spine surgery remain low across the world. Autologous blood transfusion may obviate the need for homologous transfusion completely. We encourage spine surgeons to consider autologous blood transfusion wherever feasible.

The aim of this 12-year case series was to review the drugs used during anesthetic management of patients with diagnosis of or risk criteria for Brugada syndrome (BrS), and to document any possible association between these drugs and arrhythmogenic activity or unexplained hemodynamic instability. A retrospective clinical observational study. Tertiary hospital. Thirty-one patients met our inclusion criteria: 20 belonging to group D (diagnosed BrS) and 11 to group R (risk of BrS). They underwent a total of 43 anesthetic interventions (28 in group D and 15 in group R). Records from patients with or at risk of BrS who underwent anesthetic intervention at our hospital between May 2003 and May 2015 were retrospectively reviewed. Drugs used were compared with those recommended to be avoided or preferably avoided, published by specialists in the field at brugadadrugs.org. Hemodynamic and cardiac complications during anesthesia were assessed for hypothetical association with these drugs. From the list of drugs available in medical literature recommended to avoid in BrS patients the following were used in our series: propofol (n = 8 in group D, n = 8 in group R), local anesthetics (n = 15 in group D, n = 8 in group R), tramadol (n = 1 in group D), and metoclopramide (n = 1 in group D). Hemodynamic complications occurred in 5 procedures, but no direct association was found between these events and the use of the drugs listed above. Major adverse events related to the deleterious effects of drugs recommended to be avoided were not detected in our series of patients with or at risk of BrS. Although authors cannot refute the theoretical risk of major adverse advents when using known or potential BrS triggers, the true clinical risk of these drugs is unknown, and recommendations to avoid their use should be better supported.

Secondary cranioplasty with customized craniofacial implants (CCIs) are often used to restore cerebral protection and reverse syndromes of the trephined, and for reconstruction of acquired cranial deformities. The 2 most widely used implant materials are polyetheretherketone and poly(methylmethacrylate) (PMMA). Previous series with CCIs report several major complications, including implant infection leading to removal, extended hospital stays, and surgical revisions. With this in mind, we chose to review our large case series of 22 consecutive PMMA CCI cranioplasties treated by a single craniofacial surgeon. A cohort of 20 consecutive patients receiving 22 PMMA implants during a 2-year period was identified and outcomes reviewed. The mechanism of initial insult, time from craniectomy to cranioplasty, anesthesia time, major and minor postoperative complications, radiation history, and length of follow-up were statistically analyzed. There were no complications related to infection, hematoma/seroma, or cerebrospinal fluid leak (0/22, 0%). Two patients experienced major complications related to persistent temporal hollowing (PTH) following standard CCI cranioplasty, which required revision surgery with modified implants (2/22, 9%). One minor complication of self-resolving transient diplopia was noted (1/22, 5%). In this consecutive series, PMMA CCIs were associated with a very low complication rate, suggesting that PMMA may be a preferred material for CCI fabrication. However, with 10% (2/20) of patients experiencing PTH and dissatisfaction related to asymmetry, future research must be directed at modifying CCI shape, to address the overlying soft-tissue deformity. If successful, this may increase patient satisfaction, prevent PTH, and avoid additional costs of revision surgery.

Surgery insight: late complications following repair of tetralogy of Fallot and related surgical strategies for management.

2006-11-01

Biventricular correction of tetralogy of Fallot was devised more than 50 years ago. Current short-term outcomes are excellent. The potential for late complications is, however, an important concern for the growing number of postrepair survivors. Progressive pulmonary valve regurgitation leading to right heart failure and arrhythmia are centrally important problems faced by these patients. New techniques are, however, likely to change the future outcomes for postrepair survivors. These techniques include percutaneous valve replacement, arrhythmia ablation surgery, and strategies that emphasize preservation of the pulmonary valve even at the cost of leaving some residual valvular stenosis. The objectives of this Review are to outline the major complications that arise late after repair of tetralogy of Fallot, to describe the surgical approaches that have been developed to avoid and manage arising complications, and to briefly explore how novel treatment paradigms could change the future long-term outlook for patients following tetralogy repair.

Preoperative oral carbohydrate therapy.

2015-06-01

Management of the postoperative response to surgical stress is an important issue in major surgery. Avoiding preoperative fasting using preoperative oral carbohydrates (POC) has been suggested as a measure to prevent and reduce the extent to which such derangements occur. This review summarizes the current evidence and rationale for this treatment. A recent review from the Cochrane Collaboration reports enhanced gastrointestinal recovery and shorter hospital stay with the use of POC with no effect on postoperative complication rates. Multiple randomized controlled trials demonstrate improved postoperative metabolic response after POC administration, including reduced insulin resistance, protein sparing, improved muscle function and preserved immune response. Cohort studies in patients undergoing major abdominal surgery have shown that the use of POC as part of an enhanced recovery after surgery protocol is a significant predictor for improved clinical outcomes. Avoiding preoperative fasting with POC is associated with attenuated postoperative insulin resistance, improved metabolic response, enhanced perioperative well-being, and better clinical outcomes. The impact is greatest for patients undergoing major surgeries.

Exploring Outcomes Related to Anxiety and Depression in Completers of a Randomized Controlled Trial of Complicated Grief Treatment.

2016-01-01

The present study examines a more fine-grained analysis of anxiety-related and depression-related outcomes amongst a sample of treatment completers who were assigned to complicated grief treatment (CGT) (n = 35) or interpersonal psychotherapy (IPT) (n = 34) in a previously reported randomized controlled trial. We examined effects of antidepressant use and measures of anxiety and depression, focusing especially on guilt related to the death or deceased and grief-related avoidance in order to further understand the differential effectiveness of CGT and IPT amongst participants who received the full course of treatment. Analyses showed that CGT produced greater reductions in anxiety and depressive symptoms including negative thoughts about the future and grief-related avoidance. CGT's advantage over IPT in lowering depression was most pronounced amongst those not taking antidepressants. Our results further elucidate CGT effects and support the idea that CG and major depressive disorder are distinct conditions. Targeted treatment for complicated grief (CG) produces benefits in associated mood and anxiety symptoms and CG symptoms. Amongst patients with CG, interpersonal psychotherapy seems relatively ineffective in ameliorating depressive symptoms. Grief-related depressive symptoms may not respond to standard treatments unless CG symptoms are also addressed. Reducing grief-related symptoms, such as anxieties about the future, guilt related to the death or deceased and avoidance of reminders of the loss may be important aspects in reducing CG.

Kim, Youn Hwan; Kim, Sang Wha; Kim, Jeong Tae; Kim, Chang Yeon

2013-06-01

Tensor fascia lata (TFL) musculocutaneous flaps often require a donor site graft when harvesting a large flap. However, a major drawback is that it also sacrifices the muscle. To overcome this disadvantage, we designed a TFL perforator-based island flap that was harvested from a site near the defect and involved transposition within 90 degrees without full isolation of the pedicles. We performed procedures on 17 musculocutaneous flaps and 23 perforator-based island flaps, and compared the outcomes of these surgeries. The overall complication rate was 27.5% (11 regions). There were 7 complications related to the musculocutaneous flaps and 4 complications related to the perforator flaps. Although there were no statistical differences between those groups, lower complication rates were associated with procedures involving perforator flaps. The TFL perforator procedure is a simple and fast operation that avoids sacrificing muscle. This decreases complication rates compared to true perforator flap techniques that require dissection around the perforator or pedicle.

Exploring the role of experiential avoidance from the perspective of attachment theory and the dual process model.

2010-01-01

Avoidance can be adaptive and facilitate the healing process of acute grief or it can be maladaptive and hinder this same process. Maladaptive cognitive or behavioral avoidance comprises the central feature of the condition of complicated grief. This article explores the concept of experiential avoidance as it applies to bereavement, including when it is adaptive when it is problematic. Adaptive avoidance is framed using an attachment theory perspective and incorporates insights from the dual process model (DPM). An approach to clinical management of experiential avoidance in the syndrome of complicated grief is included.

Fostering design for avoiding small parts in commonly used objects.

2012-05-14

Injuries due to the accidental ingestion or aspiration of small parts have became a matter of interest in the last 30 years, focusing on the relationship between a proper prevention and the diminished frequency of occurrences. Small parts in commonly used objects represent a large sector of potential danger, taking explicit mouthing behavior of children in the first four years of life. In this paper the intent is to show the current situation of design projects and legislation around the world, meant to avoid the casual accidents due to manufacturing reasons. Proposed process and quality control standards seek to eliminate production errors and control materials to avoid deviation from the design. The present study draws its data from the Susy Safe registry, a European Commission co-funded project started in February 2005, whose aim is to establish an international registry of cases of Foreign Bodies (FB) injuries in children aged 0-14 years. Information collected from the data base concern age and gender of the child, location, shape, volume, consistency and elipticity of the foreign body, any complication occurred, hospitalization, and behavioral aspects linked to the injury, like the supervision of the parents or the activity concomitant to the injury. Cases are prospectively collected using the Susy Safe system from 06/2005; moreover, also information regarding past consecutive cases available in each center adhering to the project have been entered in the Susy Safe Registry. Data evidenced that the majority of small parts related injuries are related to stationery. The majority of objects (56.7%), were located in the nose, followed by the ears (31.5%). The distribution on incidence of FB injuries by age class shows that the majority of injuries due to small parts in common objects occurred in children older than >3 years. Male and female were affected with the same frequency when concerning the nose, while all other locations showed a higher frequency in males. Data suggested that hospitalization occurred in 32% of those who compiled the form, resulting in complication just in 16% of injured. Although the most frequent location needing hospitalization was the tracheobronchial tree, the most frequent location showing complication was the nose, 80.3% of the complications, having an infection as most frequent outcome. In children younger than 1 year median volume reached 333.62 mm(3), in children between 1 and 2 years, median volume was 81.12 mm(3), in older children (>3 years) it showed 37.68 mm(3). The same considerations can be seen for the ellipticity, where the median ellipticity was 2.79 in children <1 year, while it was 1.94 in children between 1 and 2 years, and 1.17 in the older ones. Consistency is similar for all age classes, stressing that rigid small parts were those more involved in injuries with foreign bodies. Behavioral aspects pointed out that the 80% of children were playing before the accident, and 65.3% were under adults' supervision. Adult presence resulted associated to the absence of complication, with a p-value of 0.04. The study stresses the importance of primary prevention, seen as the active care of adults toward children manipulating foreign bodies potentially dangerous. This presence may not avoid the event, but in case of FBs aspiration, ingestion, insertion or inhalation, it could be the main factor leading to fewer complications. Copyright © 2012.

Upasani, Anand, E-mail: anand.upasani@gosh.nhs.uk; Barnacle, Alex, E-mail: alex.barnacle@gosh.nhs.uk; Roebuck, Derek, E-mail: derek.roebuck@gosh.nhs.uk

Conventionally, xanthogranulomatous pyelonephritis is treated with antibiotics and drainage of abscess followed by nephrectomy for definitive treatment. Surgical excision of the affected kidney carries risk of significant complications. An alternative treatment modality is described in the form of embolization of the renal artery to devascularise the renal parenchyma and ablate the renal tissue, thus avoiding a major surgical procedure and the significant risks involved.

Complications from diabetes mellitus including major lower extremity amputation may have significant impact on a patient's mortality. This study determined what impact the addition of a limb salvage and diabetic foot program involving podiatry had at an academic institution over 16years by analyzing high-low amputation ratio data. The high-low amputation ratio in the diabetic population who underwent non-traumatic amputation of the lower extremity was retrospectively evaluated at an academic institution via cohort discovery of the electronic medical record and analysis of billing over 16years. We directly compared two eras, one without podiatry and one with a podiatry presence. It was found that with the addition of a podiatry program, limb salvage rates significantly increased (R 2 (without podiatry)=0.45, R 2 (with podiatry)=0.26), with a significant change in both the rate of limb salvage per year (-0.11% per year versus -0.36% per year; p<0.01) and an overall decrease in high-low amputation ratio (0.89 without podiatry to 0.60 with podiatry). Of note, approximately 40 major lower extremity amputations were avoided per year with the addition of a podiatry program (p<0.05). Our findings signify the importance of podiatric care in the diabetic population. With an established podiatry program present at an academic institution, major lower extremity amputations can be avoided and more limbs can be salvaged, thus preventing some of the moribund complications from this condition.

Mediators of Outcome in Complicated Grief Treatment.

PubMed

Glickman, Kim; Shear, M Katherine; Wall, Melanie M

2017-07-01

In this study, we examined the mechanisms of action of complicated grief treatment (CGT), an efficacious psychotherapy for complicated grief. We explored 3 putative mediators (guilt/self-blame related to the deceased, negative thoughts about the future, and avoidance) among treatment completers assigned to either CGT (n = 35) or interpersonal psychotherapy (n = 34) in a previously reported randomized controlled trial. Antidepressant use was examined as a moderator of mediation effects. A reduction in guilt/self-blame, negative thoughts about the future, and avoidance behavior each mediated the relationship between treatment group and complicated grief outcomes. Reduction in avoidance emerged as an independent mediator after controlling for all mediators. Reducing avoidance of situations and emotions connected to the loss seems to be a key mechanism of change in CGT. Revising counterfactual thinking around troubling aspects of the death may also play a role in facilitating effective adaptation to loss. © 2016 Wiley Periodicals, Inc.

Patients undergoing abdominal surgery for solid tumours frequently develop major postoperative complications, which negatively affect quality of life, costs of care and survival. Few studies have identified the determinants of perioperative complications in this group. We performed a prospective observational study including all patients (age > 18) undergoing abdominal surgery for cancer at a single institution between June 2011 and August 2013. Patients undergoing emergency surgery, palliative procedures, or participating in other studies were excluded. Primary outcome was a composite of 30-day all-cause mortality and infectious, cardiovascular, respiratory, neurologic, renal and surgical complications. Univariate and multiple logistic regression analyses were performed to identify predictive factors for major perioperative adverse events. Of a total 308 included patients, 106 (34.4%) developed a major complication during the 30-day follow-up period. Independent predictors of postoperative major complications were: age (odds ratio [OR] 1.03 [95% CI 1.01-1.06], p = 0.012 per year), ASA (American Society of Anesthesiologists) physical status greater than or equal to 3 (OR 2.61 [95% CI 1.33-5.17], p = 0.003), a preoperative haemoglobin level lower than 12 g/dL (OR 2.13 [95% CI 1.21-4.07], p = 0.014), intraoperative use of colloids (OR 1.89, [95% CI 1.03-4.07], p = 0.047), total amount of intravenous fluids (OR 1.22 [95% CI 0.98-1.59], p = 0.106 per litre), intraoperative blood losses greater than 500 mL (2.07 [95% CI 1.00-4.31], p = 0.043), and hypotension needing vasopressor support (OR 4.68 [95% CI 1.55-27.72], p = 0.004). The model had good discrimination with the area under the ROC curve being 0.80 (95% CI 0.75-0.84, p < 0.001). Our findings suggest that a perioperative strategy aimed at reducing perioperative complications in cancer surgery should include treatment of preoperative anaemia and an optimal fluid strategy, avoiding fluid overload and intraoperative use of colloids.

Role of laser photoablative therapy and expandable metal stents in colorectal carcinoma

Metallic stents are effective in relieving colorectal obstruction in more than 80% of cases. Self expanding metallic stents allow for decompression of the proximal colon and preoperative bowel cleansing. Hence, emergent surgery for large bowel obstruction with its associated high morbidity and mortality might be avoided. Endoscopic laser photoablation and stent placement may successfully palliate inoperable colorectal cancer patients by maintaining luminal patency and avoiding the need for a colostomy. Major complications associated with metallic stents include pressure necrosis, perforation, bleeding and migration. The effectiveness of expandable metallic stents in obstructive colorectal carcinoma is critically reviewed. The authors present a concise review of the effectiveness of endoscopic laser photoablation and expandable metal stent placement.

Rocky Mountain spotted fever (RMSF) is an unusual but important dermatological condition to identify without hesitation. The classic triad of headache, fever, and a rash that begins on the extremities and travels proximally to involve the trunk is found in a majority of patients. The cutaneous centripetal pattern is a result of cell to cell migration by the causative organism Rickettsia rickettsii. Such individuals should receive prompt antimicrobial therapy and supportive care to avoid serious and potentially fatal complications.

Stent fracture in the superficial femoral and proximal popliteal arteries: literature summary and economic impacts.

Neil, Nancy

2013-06-01

To summarize available evidence regarding stent fracture in the femoropopliteal region. We searched PubMed, 2000-2011, using MeSH search terms "stents," "popliteal artery," and "femoral artery." We identified 29 original studies reporting 0% to 65% incidence of stent fracture. Fracture-related repeat revascularization could be avoided in the absence of device failure. Recently published data suggest that even a 5% rate of fracture-related reintervention would generate $118.4 million in health care cost in the United States. These excess procedures would also result in major complications and deaths that might have been avoided in the absence of stent fracture. Reported incidence and clinical relevance of femoropopliteal stent fractures vary across studies. Stent fracture may lead to repeat revascularization. These reinterventions create considerable--and potentially avoidable--economic burden for patients and payers. Further, these costs are effectively invisible wherever stent fractures are not systematically documented as the reason for reintervention.

Linked shoulder replacement: current design problems and a new design proposal.

PubMed

Mohammed, Ali Abdullah; Frostick, Simon Peter

2016-04-01

Totally constrained shoulder replacement with linked components is one of the surgical options in post-tumor resection shoulder reconstruction or in complex shoulder revision operations. In this paper, we intend to shed light on such an implant design, which provides a linked constrained connection between the humeral head and the glenoid, and to show some immediate postoperative complications, implant progression to decrease the chances of implant mechanical postinsertion failure, and a new design proposal. In our center, we use the linked prosthesis in complex revision situations; however, there have been some complications, which could be attributed mainly to the engineering and the implant design, and hence potentially avoidable by making a different design to cover for those mechanical issues. Two such complications are described in this paper. Early revisions after linked shoulder replacement implantation were needed in two occasions due to implant disconnection: one of them was due to dislodgement from the native glenoid, and the second one was due to the disengagement of the ringlet which secures the linkage mechanism between the humeral head and the implanted glenoid shell. There is a need for a more stable design construct to avoid the reported complications that needed early revision surgeries. The new design proposed is an attempt to help providing a better and more stable implant to decrease the chances of revision in those complex situations where the patient already had many major operations, and working to increase the durability of the implant is crucial.

Antenatally diagnosed abdominal cysts are common, and frequently are ovarian in origin, which usually regress spontaneously. Surgery is indicated in the infantile period in case of very large, persisting or symptomatic cysts. Many surgeons feel that watchful waiting can be justified in newborns with simple and complex cysts. We present a neonate with an ovarian cyst diagnosed antenatally by ultrasound (US) and showing persistent enlargement within 3 months after birth when reached a diameter of 13 cm. Assessment and treatment is described. The extremely large, non-resolving ovarian cysts in neonates present a major challenge for clinicians and should be treated by surgery to avoid complications. We advocate laparotomy and cystectomy when possible to avoid unnecessary loss of functional ovarian tissue.

Airway complications in the head injured.

Woo, P; Kelly, G; Kirshner, P

1989-07-01

Fifty head-injured patients who had tracheostomy were followed during rehabilitation by video fiberoptic laryngoscopy examination. Complications of aspiration (23/50), airway stenosis (13/50), and phonation dysfunction (16/24) were followed. Spontaneous resolution of aspiration may require a prolonged course. A majority of patients (37/50) had improvement and could be decannulated. Prognostic factors correlated to eventual decannulation included age, level on the Glasgow Coma Outcome Scale, and type of head injury. Those with poor neurologic improvement and glottic incompetence (13/50) are poor candidates for decannulation. Significant airway stenosis can involve both laryngeal and tracheal sites. Neurologic dysfunction may complicate the decannulation process after airway anatomy has been restored by surgery. Dysphonia resulting from intubation, peripheral laryngeal and nerve injury, or central laryngeal movement dysfunction are common. Preventive maintenance with ongoing evaluation can avoid airway crises such as aspiration pneumonia, hemoptysis, and innominate artery.

Background/Aims: The purpose of this study is to report our results using a computed tomography (CT)-guided fat transversing coaxial biopsy technique for pancreatic lesion biopsy that avoids major organs and vessels. We retrospectively reviewed the records of patients referred to our department for pancreatic mass biopsy. Patients and Methods: The records of patients (from June 2008 to August 2014) in whom biopsy was performed under CT guidance with a coaxial needle using a fat transversing technique were reviewed. Patient demographic data and biopsy outcomes were collected. We aimed to compare differences between lesion size and biopsy outcome, the independent two-samples t-test was used. Results: A total of 122 patients who underwent 17-G coaxial needle biopsy were included. The mean pancreatic lesion size was 3.2 cm, and in 30 patients it was more than 4 cm. The majority of lesions were located in the head of the pancreas (44.3%). No transorgan biopsies were performed. In most patients, the biopsy was performed via a fat traversing detour route (93.4%), and a successful diagnosis was made based on the biopsy outcome in 96.7% patients. Complications occurred in five patients (4.1%); three of the patients developed a fever, and two developed pancreatitis. All patients recovered with symptomatic treatment. Conclusion: CT-guided coaxial core biopsy of pancreatic lesions using a fat detour route appears to be a safe and effective method for obtaining pancreatic lesion biopsies with a high success rate and low complication rate.

An accepted definition of donor exclusion criteria has not been established for living donor liver transplantation (LDLT). The use of elderly donors to expand the living donor pool raises ethical concerns about donor safety. The aims of this study were (1) the comparison of the postoperative outcomes of living liver donors by age (≥ 50 versus < 50 years) and (2) the evaluation of the impact of the extent of right hepatectomy on donor outcomes. The study group included 150 donors who underwent donor right hepatectomy between October 2004 and April 2009. Extended criteria surgery (ECS) was defined as right hepatectomy with middle hepatic vein (MHV) harvesting or right hepatectomy resulting in an estimated remnant liver volume (RLV) less than 35%. The primary endpoints were donor outcomes in terms of donor complications graded according to the Clavien classification. Group 1 consisted of donors who were 50 years old or older (n = 28), and group 2 consisted of donors who were less than 50 years old (n = 122). At least 1 ECS criterion was present in 74% of donors: 57% had 1 criterion, and 17% had 2 criteria. None of the donors had grade 4 complications or died. The overall and major complication rates were similar in the 2 donor age groups [28.6% and 14.3% in group 1 and 32% and 8.2% in group 2 for the overall complication rates (P = 0.8) and the major complication rates (P = 0.2), respectively]. However, there was a significant correlation between the rate of major complications and the type of surgery in donors who were 50 years old or older. In LDLT, extending the limits of surgery comes at the price of more complications in elderly donors. Right hepatectomy with MHV harvesting and any procedure causing an RLV less than 35% should be avoided in living liver donors who are 50 years old or older.

Postoperative pulmonary complications (PPC) are a major cause of morbidity, mortality, prolonged hospital stay, and increased cost of care. Physiotherapy (PT) programs in post-surgical and critical area patients are aimed to reduce the risks of PPC due to long-term bed-rest, to improve the patient's quality of life and residual function, and to avoid new hospitalizations. At this purpose, PT programs apply advanced cost-effective therapeutic modalities to decrease complications and patient's ventilator-dependency. Strategies to reduce PPC include monitoring and reduction of risk factors, improving preoperative status, patient education, smoking cessation, intra-operative and postoperative pulmonary care. Different PT techniques, as a part of the comprehensive management of patients undergoing cardiac, upper abdominal, and thoracic surgery, may prevent and treat PPC such as secretion retention, atelectasis, and pneumonia.

The benefits of manual versus automated red blood cell exchange have rarely been documented and studies in young sickle cell disease patients are scarce. We aim to describe and compare our experience in these two procedures. Young patients (≤ 21 years old) who underwent manual- or automated-red blood cell exchange for prevention or treatment of sickle cell disease complications were included. Clinical, technical and hematological data were prospectively recorded and analyzed. Ninety-four red blood cell exchange sessions were performed over a period of 68 months, including 57 manual and 37 automated, 63 for chronic complications prevention, 30 for acute complications and one in the pre-operative setting. Mean decrease in sickle hemoglobin levels was higher in automated-red blood cell exchange (p < 0.001) and permitted a higher sickle hemoglobin level decrease per volume removed (p < 0.001), while hemoglobin and hematocrit remained stable. Ferritin levels on chronic patients decreased 54%. Most frequent concern was catheter outflow obstruction on manual-red blood cell exchange and access alarm on automated-red blood cell exchange. No major complication or alloimunization was recorded. Automated-red blood cell exchange decreased sickle hemoglobin levels more efficiently than manual procedure in the setting of acute and chronic complications of sickle cell disease, with minor technical concerns mainly due to vascular access. The threshold of sickle hemoglobin should be individualized for clinical and hematological goals. In our cohort of young patients, the need for an acceptable venous access was a limiting factor, but iron-overload was avoided. Automated red blood cell exchange is safe and well tolerated. It permits a higher sickle hemoglobin removal efficacy, better volume status control and iron-overload avoidance.

A new technique using cyanoacrylate glue is suggested for closing the transparenchymal tract following metallic endoprosthesis placement in a patient with malignant biliary obstruction complicated by ascites. With this technique, complications related to bile reflux through the transparenchymal tract would be avoided after transhepatic endoprosthesis placement in patients who have ascites. This technique would also be useful for avoiding bleeding following transhepatic portal venous puncture.

Among the variations of pectoral muscles, this case appears to be unique in the literature. This was a case of an accessory pectoral muscle which was located between pectoralis major and pectoralis minor muscles, which was discovered during a routine anatomy dissection. The accessory muscle originated from 6th and 7th ribs at costo-chondral junction, which travelled supero-laterally and inserted by fusing with fibres of pectoralis minor. This unusual muscle holds importance for surgeons while they perform dissectomies, in avoiding complications. PMID:24179919

Laparoscopic revisional bariatric surgery (RBS) is increasingly common. A tailored decision-making process is advocated. In this retrospective study, we reviewed the RBS experience of a single center, analyzing perioperative complications to provide insight into management options and midterm outcomes. Records from November 2011 to March 2015 were reviewed from prospectively maintained database. Six hundred eighteen patients underwent laparoscopic bariatric procedures; of these, 81 (13.1 %) underwent RBS. Patients with a minimum follow-up of 6 months (n = 77) were evaluated. Fifty-nine underwent revised laparoscopic sleeve gastrectomy, and 18 underwent revised Roux-en-Y gastric bypass. Indications for RBS were inadequate weight loss or weight regain in 42 cases (54.5 %) and gastroesophageal reflux disease (GERD), procedure-related complications, or technical failure in 35 cases (45.5 %). There were no deaths or conversions to open surgery. After a mean follow-up of 22 months, body mass index (BMI) decreased from 40.9 ± 6.7 to 31.9 ± 4.8 kg/m(2), mean % excess weight loss (%EWL) was 58 ± 24.3 %, and 55.3 % of patients had resolution of comorbidities. Eight major complications (10.4 %) occurred: five leaks and three intra-abdominal hematomas. Non-surgical management succeeded in 50 % of complications. This study confirms that RBS is challenging; a complication rate of 10 % is expected. Major surgery can be avoided when devoted endoscopists and radiologists are available. Intensive follow-up after complications allows early diagnosis and treatment of unfavorable sequelae. RBS induced a mean %EWL of 58 % at 2 years and resolution of comorbidities in 50 % of cases. However, the durability of these effects remains questionable.

SUMMARY The pectoralis major myocutaneous flap (PMMF) is a safe and versatile flap used widely for head and neck cancer reconstructions, but one of the major and most feared complications is oro- or pharyngocutaneous fistula. Herein, we attempt to establish risk factors for fistula formation in reconstructions of mucosal defects in the head and neck using PMMF through retrospective analysis of PMMF performed during 3 years at a single institution, with a total of 84 procedures. There were 69 men and 15 women, with a mean age of 59.5 years. There were 15 cases of partial flap loss, two total flap losses and 31 fistulas. The independent risk factors for fistula formation were preoperative serum hemoglobin < 13 g/dl, preoperative serum albumin < 3.4 g/dl and hypopharynx reconstruction. The PMMF is still a very useful flap and this is the first multivariate analysis analysing risk factors for fistula formation. These findings are helpful in selecting patients with elevated risk of fistula formation, and therefore preventive measures can be undertaken to avoid potentially serious complications.

2015-01-01

The prevalence of type 2 diabetes mellitus (T2DM) is increasing all over the world. Targeting good glycemic control is fundamental to avoid the complications of diabetes linked to hyperglycemia. This narrative review is based on material searched for and obtained via PubMed up to April 2015. The search terms we used were: ‘hypoglycemia, diabetes, complications’ in combination with ‘iatrogenic, treatment, symptoms.’ Serious complications might occur from an inappropriate treatment of hyperglycemia. The most frequent complication is iatrogenic hypoglycemia that is often associated with autonomic and neuroglycopenic symptoms. Furthermore, hypoglycemia causes acute cardiovascular effects, which may explain some of the typical symptoms: ischemia, QT prolongation, and arrhythmia. With regards to the latter, the night represents a dangerous period because of the major increase in arrhythmias and the prolonged period of hypoglycemia; indeed, sleep has been shown to blunt the sympatho-adrenal response to hypoglycemia. Two main strategies have been implemented to reduce these effects: monitoring blood glucose values and individualized HbA1c goals. Several drugs for the treatment of T2DM are currently available and different combinations have been recommended to achieve individualized glycemic targets, considering age, comorbidities, disease duration, and life expectancy. In conclusion, according to international guidelines, hypoglycemia-avoiding therapy must reach an individualized glycemic goal, which is the lowest HbA1c not causing severe hypoglycemia and preserving awareness of hypoglycemia.

2018-05-12

To discuss the potentially significant complications associated with medial patellofemoral ligament (MPFL) reconstruction. Additionally, to review the most current and relevant literature with an emphasis on avoiding these potential complications. Multiple cadaveric studies have characterized the anatomy of the MPFL and the related morphologic abnormalities that contribute to recurrent lateral patellar instability. Such abnormalities include patella alta, excessive tibial tubercle to trochlear grove (TT-TG) distance, trochlear dysplasia, and malalignment. Recent studies have evaluated the clinical outcomes associated with the treatment of concomitant pathology in combination with MPFL reconstruction, which is critical in avoiding recurrent instability and complications. Although there remains a lack of consensus regarding various critical aspects of MPFL reconstruction, certain concepts remain imperative. Our preferred methods and rationales for surgical techniques are described. These include appropriate work up, a combination of procedures to address abnormal morphology, anatomical femoral insertion, safe and secure patellar fixation, appropriate graft length fixation, and thoughtful knee flexion during fixation.

Transarterial radioembolization consist in delivering small particles loaded with Yttrium90, a pure beta emitter, in order to treat primary and secondary liver tumors. This treatment needs precaution since inadequate delivery of these beads can lead to severe complications. Moreover, a precise radiation dosing is crucial to achieve a good clinical success and to avoid complications such as radioembolization-induced liver disease. This review describes all the precautions and highlights clinical and technical considerations that need to be taken to avoid complications.

Pancreatits after endoscopic retrograde cholangio-pancreatography

2007-01-01

Pancreatitis is the most common complication after endoscopic retrograde cholangio-pancreatography (ERCP); the reported incidence of this complication varies from less than 1% to 40%, but a rate of 4%-8% is reported in most prospective studies involving non-selected patients. Differences in criteria for defining pancreatitis, methods of data collection, and patient populations (i.e. number of high-risk patients included in the published series) are factors that are likely to affect the varying rates of post-ERCP pancreatitis. The severity of post-ERCP pancreatitis (PEP) can range from a minor inconvenience with one or two days of added hospitalization with full recovery to a devastating illness with pancreatic necrosis, multiorgan failure, permanent disability, and even death. Although, most episodes of PEP are mild (about 90%), a small percentage of patients (about 10%) develop moderate or severe pancreatitis. In the past, PEP was often viewed as an unpredictable and unavoidable complication, with no realistic strategy for its avoidance. New data have aided in stratification of patients into PEP risk categories and new measures have been introduced to decrease the risk of PEP. As most ERCPs are performed on an outpatient basis, the majority of patients will not develop PEP and can be discharged. Alternatively, early detection of those patients who will go on to develop PEP can guide decisions regarding hospital admission and aggressive management. In the last decade, great efforts have been addressed toward prevention of this complication. Points of emphasis have included technical measures, pharmacological prophylaxis, and patient selection. This review provides a comprehensive, evidence-based assessment of published data on PEP and current suggestions for its avoidance. PMID:17569133

Microvascular Decompression for Trigeminal Neuralgia: Technical Refinement for Complication Avoidance.

Tomasello, Francesco; Esposito, Felice; Abbritti, Rosaria V; Angileri, Filippo F; Conti, Alfredo; Cardali, Salvatore M; La Torre, Domenico

2016-10-01

Microvascular decompression (MVD) represents the most effective and safe surgical option for the treatment of trigeminal neuralgia since it was first popularized by Jannetta 50 years ago. Despite several advances, complications such as cerebellar and vascular injury, hearing loss, muscular atrophy, cerebrospinal fluid (CSF) leak, postoperative cutaneous pain, and sensory disturbances still occur and may negatively affect the outcome. We propose some technical nuances of the surgical procedure that were used in our recent series. We used a novel hockey stick-shaped retromastoid skin incision, preserving the major nerves of the occipital and temporal areas. Microsurgical steps were performed without the use of retractors. CSF leakage was prevented with a watertight dural closure and multilayer osteodural reconstruction. The refined surgical steps were perfected in the last consecutive 15 cases of our series. In these cases we did not record any cutaneous pain, sensory disturbances, or CSF leakage. The average diameter of the craniectomy was 18 mm. No patient reported major complications related to the intradural microsurgical maneuvers. In all cases the neurovascular conflict was found and solved with a good outcome in terms of pain disappearance. Our minimally invasive approach was demonstrated to guarantee an optimal exposure of the cerebellopontine angle and minimize the rate of complications related to skin incision and muscular dissection, microsurgical steps, and closure.

To determine the frequency of avoidable neonatal neurological damage. We carried out a retrospective study from January 1st to December 31st 2003, including all children transferred from a level I or II maternity unit for suspected neurological damage (SND). Only cases confirmed by a persistent abnormality on clinical examination, EEG, transfontanelle ultrasound scan, CT scan or cerebral MRI were retained. Each case was studied in detail by an expert committee and classified as "avoidable", "unavoidable" or "of indeterminate avoidability." The management of "avoidable" cases was analysed to identify potentially avoidable factors (PAFs): not taking into account a major risk factor (PAF1), diagnostic errors (PAF2), suboptimal decision to delivery interval (PAF3) and mechanical complications (PAF4). In total, 77 children were transferred for SND; two cases were excluded (inaccessible medical files). Forty of the 75 cases of SND included were confirmed: 29 were "avoidable", 8 were "unavoidable" and 3 were "of indeterminate avoidability". Analysis of the 29 avoidable cases identified 39 PAFs: 18 PAF1, 5 PAF2, 10 PAF3 and 6 PAF4. Five had no classifiable PAF (0 death), 11 children had one type of PAF (one death), 11 children had two types of PAF (3 deaths), 2 had three types of PAF (2 deaths). Three quarters of the confirmed cases of neurological damage occurring in levels I and II maternity units of the Aurore network in 2003 were avoidable. Five out of six cases resulting in early death involved several potentially avoidable factors.

AIM: To compare safety and therapeutic efficacy of laparoscopic radiofrequency (RF) ablation vs computed tomography (CT)-guided RF ablation for large hepatic hemangiomas abutting the diaphragm. METHODS: We retrospectively reviewed our sequential experience of treating 51 large hepatic hemangiomas abutting the diaphragm in 51 patients by CT-guided or laparoscopic RF ablation due to either the presence of symptoms and/or the enlargement of hemangioma. Altogether, 24 hemangiomas were ablated via a CT-guided percutaneous approach (CT-guided ablation group), and 27 hemangiomas were treated via a laparoscopic approach (laparoscopic ablation group). RESULTS: The mean diameter of the 51 hemangiomas was 9.6 ± 1.8 cm (range, 6.0-12.0 cm). There was no difference in the diameter of hemangiomas between the two groups (P > 0.05). RF ablation was performed successfully in all patients. There was no difference in ablation times between groups (P > 0.05). There were 23 thoracic complications in 17 patients: 15 (62.5%, 15/24) in the CT-guided ablation group and 2 (7.4%, 2/27) in the laparoscopic ablation group (P < 0.05). According to the Dindo-Clavien classification, two complications (pleural effusion and diaphragmatic rupture grade III) were major in two patients. All others were minor (grade I). Both major complications occurred in the CT-guided ablation group. The minor complications were treated successfully with conservative measures, and the two major complications underwent treatment by chest tube drainage and thoracoscopic surgery, respectively. Complete ablation was achieved in 91.7% (22/24) and 96.3% (26/27) in the CT-guided and the laparoscopic ablation groups, respectively (P > 0.05). CONCLUSION: Laparoscopic RF ablation therapy should be used as the first-line treatment option for large hepatic hemangiomas abutting the diaphragm. It avoids thermal injury to the diaphragm and reduces thoracic complications. PMID:26019459

A leadless intracardiac transcatheter pacing system has been designed to avoid the need for a pacemaker pocket and transvenous lead. In a prospective multicenter study without controls, a transcatheter pacemaker was implanted in patients who had guideline-based indications for ventricular pacing. The analysis of the primary end points began when 300 patients reached 6 months of follow-up. The primary safety end point was freedom from system-related or procedure-related major complications. The primary efficacy end point was the percentage of patients with low and stable pacing capture thresholds at 6 months (≤2.0 V at a pulse width of 0.24 msec and an increase of ≤1.5 V from the time of implantation). The safety and efficacy end points were evaluated against performance goals (based on historical data) of 83% and 80%, respectively. We also performed a post hoc analysis in which the rates of major complications were compared with those in a control cohort of 2667 patients with transvenous pacemakers from six previously published studies. The device was successfully implanted in 719 of 725 patients (99.2%). The Kaplan-Meier estimate of the rate of the primary safety end point was 96.0% (95% confidence interval [CI], 93.9 to 97.3; P<0.001 for the comparison with the safety performance goal of 83%); there were 28 major complications in 25 of 725 patients, and no dislodgements. The rate of the primary efficacy end point was 98.3% (95% CI, 96.1 to 99.5; P<0.001 for the comparison with the efficacy performance goal of 80%) among 292 of 297 patients with paired 6-month data. Although there were 28 major complications in 25 patients, patients with transcatheter pacemakers had significantly fewer major complications than did the control patients (hazard ratio, 0.49; 95% CI, 0.33 to 0.75; P=0.001). In this historical comparison study, the transcatheter pacemaker met the prespecified safety and efficacy goals; it had a safety profile similar to that of a transvenous system while providing low and stable pacing thresholds.

Diabetic patients on insulin and sulphonylureas are at risk of developing hypoglycaemia. Many patients do not respond appropriately because of poor knowledge and understanding of the symptoms of hypoglycaemia, which if not promptly treated can lead to permanent neurological and renal damage. Hypoglycaemic complications can be avoided if patients have a good knowledge of the early symptoms of hypoglycaemia and know how to respond appropriately. The aim of this study was to assess the knowledge of adult diabetic patients attending a diabetic clinic about symptoms of hypoglycaemia and how they responded to these symptoms. A hospital-based diabetic clinic in northern KwaZulu-Natal. This was a cross-sectional, descriptive study involving 200 diabetic patients. Demographic data and details of current medication, knowledge of hypoglycaemia and how patients responded to the symptoms were collected using a validated questionnaire. The majority of the patients had fair to good knowledge of hypoglycaemia; however, less than 25% knew what action to take when they experienced symptoms suggestive of hypoglycaemia. There is a need to improve the education given to diabetic patients on stepwise measures to take to avoid life-threatening complications associated with hypoglycaemia.

Avoiding unfavourable outcomes in liposuction

Khanna, Atul; Filobbos, George

2013-01-01

The origin of liposuction can be traced to an adverse event by Dujarrier in 1921 when he used a uterine curette to remove fat from the knees of a ballerina ending in an amputation secondary to damage of the femoral artery. The history of liposuction since then has been one of avoiding complications and optimising outcome. After this adverse event, liposuction was abandoned until the 1960's when Schrudde revived the practice using small stab incisions and sharp curettage with the secondary suction to aspirate the freed tissue. This technique was associated with a high incidence of complications especially seroma and skin necrosis. Illouz then replaced the curette with a blunt cannula connected to vacuum pump thus avoiding the complications of a sharp curette. Despite the presence of various techniques for liposuction, suction assisted liposuction (SAL) is still the standard technique of liposuction. This article aims to discuss literature regarding the various aspects of liposuction (SAL) and to highlight the salient points in the literature and in the senior author's experience in order to avoid unfavourable outcomes in liposuction. A literature review on avoiding complication is in liposuction including some of the seminal papers on liposuction. Liposuction is generally a safe procedure with reproducible outcome. Just like any surgical procedure it should be treated with the utmost care. Illouz published 10 commandments for liposuction in 1989 and we review these commandments to demonstrate how liposuction has evolved. PMID:24501475

To investigate the clinical manifestations, complications and treatment of medicament-like dermatitis due to trichloroethylene (TCE), so as to provide basis for studying its etiology and mechanism. Fifty patients with dermatitis due to TCE from 1997 to 2000 were analysed retrospectively. The occurrence of the dermatitis was not parallel to TCE exposure levels, without significant dose-effect relationship. This disease could be caused by both inhalation and skin exposure. The latency period of TCE dermatitis ranged from 5 to 66 days, and the average was 31.5 d (Medium). The major clinical manifestations included skin lesions, fever, superficial lymph node swelling and liver dysfunction. Infection was the major complication. Glucocorticoid was effective for treatment of this disease. The clinical manifestations due to TCE exposure were similar to dermatitis medicamentosa. The major clinical types of TCE dermatitis included exfoliative dermatitis and erythema multiforme. The dermatitis is considered to be mediated by delayed-type (IV) hypersensitivity. The key factors to treat this disease successfully included the use of glucocorticoid in time with sufficient dose and full course, professional skin care, active treatment to protect the liver and to avoid infection.

Arterial access is a major site of bleeding complications after invasive coronary procedures. Among strategies to decrease vascular complications, the radial approach is an established one. Vascular closure devices provide more comfort to patients and decrease hemostasis and need for bed rest. However, the inconsistency of data proving their safety limits their routine adoption as a strategy to prevent vascular complications, requiring evidence through adequately designed randomized trials. The aim of this study is to compare the radial versus femoral approach using a vascular closure device for the incidence of arterial puncture site vascular complications among non-ST-segment elevation acute coronary syndrome patients submitted to an early invasive strategy. ARISE is a national, multicenter, non-inferiority randomized clinical trial. Two hundred patients with non-ST-segment elevation acute coronary syndrome will be randomized to either radial or femoral access using a vascular closure device. The primary outcome is the occurrence of vascular complications at an arterial puncture site 30 days after the procedure, including major bleeding, retroperitoneal hematoma, compartment syndrome, hematoma ≥ 5 cm, pseudoaneurysm, arterio-venous fistula, infection, limb ischemia, arterial occlusion, adjacent nerve injury or the need for vascular surgical repair. Enrollment was initiated in September 2012, and until October 2013 91 patients were included. The inclusion phase is expected to last until the second half of 2014. The ARISE trial will help define the role of a vascular closure device as a bleeding avoidance strategy in patients with NSTEACS. ClinicalTrials.gov identifier: NCT01653587.

Major neurovascular complications of clavicle fracture surgery

PubMed Central

Clitherow, Harry DS

2014-01-01

Clavicle fracture fixation is becoming an increasingly common operation, with good clinical outcomes and a low rate of significant complications. However, there are several reports of rare but potentially life or limb threatening, neurovascular complications. Arterial injuries are usually pseudoaneurysms associated with prominent screws. These may be clinically silent for several years before presenting as subcritical upper limb ischaemia. Venous injuries are a result of tearing of the vessel wall by fracture manipulation, drills or implants. This produces intra-operative haemorrhage and potentially air embolism, which can be fatal if not rapidly recognized and managed. Brachial plexopathy is the result of traction on adherent plexus or impingement by fracture fragments or callus. It presents as severe arm pain and paralysis immediately postoperatively. Neurovascular injuries can be avoided by a combination of pre-operative planning, communication with anaesthetic staff and strategic surgical technique. The plane of the surgical exposure, release of the soft tissues, drill direction and depth and screw length are all important factors. PMID:27582950

Surgical Management of Complicated Necrotizing Pneumonia in Children.

There are no well-established indications for the surgical management of acute necrotizing pneumonitis in children. This study presents our experience regarding this challenging topic. Between 2002 and 2009, 56 necrotizing pneumonitis patients with empyema were treated surgically. The outcomes were analyzed retrospectively. Computed tomography findings of massive lung necrosis or large cavities involving more than 50% of the involved lobe were deemed to be complicated necrotizing pneumonitis. Patients without the above indications were considered uncomplicated. Thirty-one cases were uncomplicated and 25 were complicated. Operative procedures included 38 decortications (31 uncomplicated and seven complicated), 14 wedge resections, and four lobectomies (complicated only). Preoperatively, patients with complicated necrotizing pneumonia had a higher incidence of pneumothorax (32% vs. 14.3%; p = 0.001), endotracheal intubation (44% vs. 9.7%; p = 0.008), and hemolytic uremic syndrome (20% vs. 3.2%; p = 0.01). These patients also had higher incidences of intraoperative transfusion (68% vs. 9.7%; p = 0.03), major postoperative complications (16% vs. 0%; p = 0.02), reoperations (16% vs. 0%; p = 0.02), and longer postoperative stay (19.8 ± 24.2 days vs. 11.2 ± 5.8 days; p = 0.03). Four complicated patients, who initially had decortications and limited resections, underwent reoperations. Compared with uncomplicated patients, those who underwent decortications and wedge resection required longer postoperative stays (23.6 ± 9.9 days, p < 0.01 and 21.1 ± 30.7 days, p = 0.04, respectively), whereas patients who had lobectomy had a similar duration of recovery (9.0 ± 2.1 days, p = 0.23). All patients improved significantly at follow-up. Children with complicated necrotizing pneumonitis have more preoperative morbidities, more major postoperative complications, and require longer postoperative stays. Aggressive surgical treatment results in significant clinical improvement. Lobectomy in patients with complicated necrotizing pneumonitis may shorten the postoperative course and avoid subsequent surgery. Copyright © 2016. Published by Elsevier B.V.

It has been reported diverse factors associated with this medical complication. to identify the risk factors with significant association with dystocic delivery. a case-control study was carried out. There were included 750 patients, divided into 250 women with dystocic deliveries (cases) and 500 women with eutocic deliveries (controls). Demographic and clinical variables were registered. The statistical analysis was performed with percentages, arithmetic media, standard deviation, Student t test, chi2 and logistic regression analysis. An alpha value was set at 0.05. the factors with statistical significance were: advanced age (p < 0.001), major patient's height (p < 0.001), major new born's weight (p = 0.009), lower parity (p < 0.001), and prolonged duration of labor (p = 0.04). Other variables such as number of pregnancies, previous cesarean sections, spontaneous abortions, weight of the patient, weight earned during pregnancy, number of medical appointments during antenatal care, previous dystocic delivery, and premature rupture of the membranes, were not significant. there are clinical and demographic risk factors associated with dystocic delivery. To identify this risk factors during the antenatal care could diminish the frequency of dystocic deliveries and therefore to avoid the associated maternal-fetal complications.

Esophageal dilatation using the Eder Puestow dilators.

PubMed

Royston, C M; Dowling, B L; Gear, M W

1976-06-01

We have performed fifty-one dilatations in twenty-six patients using an end-viewing fiberoptic endoscope and Eder Puestow dilators. All (except two) were performed using intravenous diazepam, the majority on an outpatient basis. The only complication has been a single case of aspiration pneumonia. We have found this method of esophageal dilatation particularly useful in the preoperative dilatation of benign strictures, and in those elderly frail patients who are unsuitable for surgery. Transthoracic resection of the stricture is avoided and thus transabdominal repair of the hiatus hernia may be undertaken.

Peripheral arterial occlusive disease (PAD) includes acute and chronic disorders of the blood supply as a result of obstruction of blood flow in the arteries of the limb. Treatment of PAD can be conservative, surgical and endovascular. Percutaneous transluminal angioplasty with or without stenting has become a recognized method, which is increasingly used in treatment of arterial occlusive disease. This study aimed to determine early results of endovascular treatment of critical limb ischemia (CLI) patients with infrapopliteal lesions. The study included 69 patients (46 men; mean age 65 years, range 38-84) with CLI (class 4 to 6 according to Rutherford). The primary study endpoints were absence of major amputation of the target limb at 6 months and occurance of local and systemic complications specifically related to use of endovascular treatment. Major amputation was avoided in 61 patients. Through 6 months, 6 patients underwent additional revascularization. One local complication (clinicaly significant dissection of popliteal artery) occurred, and it was resolved by stent implantation. There were no cases of systemic complications and death during the follow-up period. Rates of major amputation were 12.3% for diabetics versus 8.3% for non-diabetics. Our data showed that endovascular treatment of infrapopliteal disease is an effective and safe treatment in patients experiencing CLI, provides high limb preservation and low complication rates. Study outcomes support endovascular treatment as a primary option for patients experiencing CLI due to below the knee (BTK) occlusive disease. © 2018 The Author(s).

The use of interventional radiology has increased as the first-line management of complications after pancreatic resections. Patients in whom interventional radiology was performed were compared with those in whom interventional radiology was not performed as regards type of pancreatic resection, diagnosis, postoperative mortality and morbidity, postoperative pancreatic fistula postpancreatectomy haemorrhage, bile leakage, reoperation rate and length of hospital stay. Our aim was to evaluate the usefulness of interventional radiology in the treatment of complications after pancreatic resection. One hundred and eighty-two (62.8%) out of 290 patients experienced postoperative complications. Interventional radiology procedures were performed in 37 cases (20.3%): percutaneous drainage in 28, transhepatic biliary drainage in 8 and arterial embolisation in 3 cases. Technical success was obtained in all cases and clinical success in 75.7%. Reoperation was avoided in 86.5%. In patients with major complications, clinically relevant postoperative pancreatic fistula and bile leaks as well as those with late postpancreatectomy haemorrhage (P=0.030) and patients with postpancreatectomy haemorrhage grade C (P=0.029), interventional radiology was used (P<0.001, P<0.001 and P=0.009, respectively) significantly more frequently than in the remaining patients. The reoperation and mortality rates were similar in the two groups (P=0.885 and P=0.100, respectively) while patients treated with interventional radiology procedures had a significant longer length of hospital stay than those in the non-interventional radiology group (37.5 ± 23.4 vs. 18.7 ± 11.7 days; P<0.001). Interventional radiology procedures were useful, especially for patients with postoperative pancreatic fistulas and bile leaks in whom reoperation was very often avoided.

Modified incision for maxillectomy: our experience.

Radical maxillectomy has usually been done by the classical Weber Ferguson incision since age old times and still is being used widely due to its advantage of excellent exposure and minimal scarring as the incision follows the natural skin crease. In our modification of radical maxillectomy incision we avoid a scar on the midface by performing a midface degloving and combining it with a subconjunctival eye incision thus avoiding any cosmetic deformity and associated eye complication. It also avoids the late complication of cutaneous fistula following radiotherapy to these areas and due to early healing of the wound, early radiotherapy can be started.

Four years’ experience in uniportal video-assisted thoracoscopic surgery for major lung resections: influence of silicosis in clinical outcomes

PubMed Central

Pérez Méndez, Itzell

2016-01-01

Background Crystalline silica (CS) is one of the most common minerals and a common particulate air pollutant in both working and living environments. Lung cancer is considered one of the serious consequences of silica exposure. This paper gives an overview of the role of silicosis in results of perioperative and postoperative of lung resection surgery performed by the most up to date video-assisted thoracoscopic surgery (VATS) approach: the uniportal VATS. Methods In January 2012 a program of video-assisted thoracoscopic anatomic pulmonary resections through a uniportal approach (no rib spreading) was started in our institution by a single surgeon experienced in postero-lateral open major resections and in other VATS procedures except lobectomies. We have retrospectively reviewed our first 4 years of experience in which 128 consecutive patients had undergone this approach, setting as a variable comparison of the results the presence of silicosis. Results Between January 2012 to December 2015, 128 anatomical resections where attempted. Of these attempted major resections, 115 (90%) were successfully completed. Out of 128 patients 21 (16%) had a diagnosis of complex silicosis. The most frequent resection was left upper lobectomy. The mean surgical time was 178±65 min. The median postoperative chest drain time was 3 days and the median postoperative hospital stay time was 3 days. There were 25 (19%) minor complications 17 (68%) of them in the first year of experience, and 3 (2.3%) had major complications. Preoperative forced expiratory volume in one second (FEV1) less than 60%, diagnosis of chronic obstructive pulmonary disease (COPD) and silicosis have been predictive of postoperative minor complications. Conclusions The uniportal VATS for major anatomic lung resections is reproducible and safe with good results when performed by surgeons experienced in both open major resections (anterior or postero-lateral thoracotomy), and multiport VATS minor procedures, even in highly complex cases such as patients with silicosis. Presence of silicosis should be taken into account as a predictive factor for postoperative complications. Therefore, overestimation of the benefits of the procedure in the patient selection process especially in the initial part of the experience must be avoided. PMID:29399482

2016-01-01

Summary Background Recent developments in hip arthroscopic techniques and technology have made it possible in many cases to avoid open surgical dislocation for treating a variety of pathology in the hip. Although early reports suggest favourable results’ using hip arthroscopy and it has been shown to be a relatively safe procedure, complications do exist and can sometimes lead to significant morbidity. Methods This is a review article. The aim of this manuscript is to present the most frequent and/or serious complications that could occur at or following hip arthroscopy and some guidelines to avoid these complications. Conclusion Most complications of hip arthroscopy are minor or transient but serious complications can occur as well. A lot of complication e.g. acetabular labral puncture go unreported. Appropriate education and training, precise and meticulous surgical technique with correct instrumentation, the right indication in the right patient and adherence to advice from mentors and experienced colleagues are all essential factors for a successful outcome.

PubMed

Klopp, Michael; Hoffmann, Hans; Dienemann, Hendrik

2015-03-01

A chest tube is used to drain the contents of the pleural space to reconstitute the physiologic pressures within the pleural space and to allow the lungs to fully expand. Indications for chest tube placement include pneumothorax, hemothorax, pleural effusion, pleural empyema, and major thoracic surgery. The most appropriate site for chest tube placement is the 4th or 5th intercostal space in the mid- or anterior- axillary line. Attention to technique in placing the chest tube is vital to avoid complications from the procedure. Applying the step-by-step technique presented, placement of a chest tube is a quick and safe procedure. Complications - frequently occurring when the tube is inserted with a steel trocar - include hemothorax, dislocation, lung lacerations, and injury to organs in the thoracic or abdominal cavity." © Georg Thieme Verlag KG Stuttgart · New York.

Intraoperative fracture of phacoemulsification sleeve

PubMed Central

2010-01-01

Background We describe a case of intraoperative fracture of phacoemulsification sleeve during phacoemulsification surgery. Case presentation Phacoemulsification surgery was performed in the left eye of a 58-year-old lady with grade II nuclear sclerosis & grade I cortical cataract. Towards the end of quadrant removal, there was anterior chamber instability with impaired followability of nuclear fragments. The distal part of the fractured sleeve remained inside the anterior chamber upon removal of the phacoemulsification probe. The retained sleeve was retrieved with a pair of forceps through the corneal incision site, which did not require widening. There was no missing fragments retained intraocularly and the patient had an uneventful recovery with vision of 20/25 at three months post-operatively. Conclusion Phacoemulsification sleeve fracture is an uncommon complication. With early identification of this condition and proper management, major complications can be avoided. PMID:21118542

Anastomotic stricture complicating esophagectomy.

PubMed

Rice, Thomas W

2006-02-01

Regardless of the definition, anastomotic strictures are a common complication after esophagectomy and adversely affect quality of life. They are best avoided by careful surgical technique that minimizes conduit ischemia during preparation, placement, and anastomosis. Anastomotic technique must assure an adequate anastomotic area. The Collard anastomosis, a significant advance in the construction of esophagogastric anastomoses, routinely assures adequate anastomotic area and thus assures fewer anastomotic strictures. The use of small-diameter (21-mm and 25-mm) circular staplers is discouraged, because they are unquestionably associated with the occurrence of major anastomotic strictures. Anastomotic leaks precede many anastomotic strictures, but strictures are not inevitable after leaks. Other variables are less reliably associated with anastomotic strictures. Treatment requires diagnosis and exclusion of recurrent cancer and other causes of stricture. Dilation is safe, but diligence with repeated sessions is necessary to restore swallowing. Reoperation is rarely required.

Axillary breast: Navigating uncharted terrain

Bhave, Medha A

2015-01-01

Introduction: Axillary breast is a common condition that leads to discomfort and cosmetic problems. Liposuction alone and open excision are two techniques used for treatment. Materials and Methods: This study assesses the results of treatment in 24 consecutive patients, operated between 2005 and 2015. All patients had Kajava class IV masses. Three were treated by liposuction alone, while 21 were treated by open axillaplasty with limited liposuction. Results: One patient treated by liposuction alone had to be re-operated for a residual lump, while with axillaplasty, no major complications were observed and the results were uniformly good. Discussion: Certain points of technique emerged as major determinants in obtaining the best results. In brief, these are: a) limited skin excision; b) placing elliptical incisions within the most lax, apical axillary skin, irrespective of the location of the lump; c) raising skin flaps at the level of superficial fascia; d)meticulous dissection and preservation of the nerves, especially the second intercostobrachial; f) judicious liposuction for eliminating dog ears and axillary sculpting only; g) avoiding drains. Conclusion: Open axillaplasty with limited liposuction is the best way to minimise complications and produce good results. PMID:26933282

Crossed renal ectopia is a rare pathology that is often asymptomatic. Intraoperative detection with a sigma complicated neoplasia is more infrequent and requires correct management to avoid a renal ureteral injury. To present a case report of a patient with a sigma complicated neoplasia and a crossed renal ectopia detected incidentally. We present the case of a 62-year-old man that was submitted for emergency surgery for a sigma perforated neoplasm, and who presented with a previously undiagnosed left-side CRE. During surgery there was a need to insert 2-double-J stents as a guide to both ureters and to avoid any injury to them. Crossed renal ectopia is a rare, often asymptomatic entity, the diagnosis of which is usually incidental. In our case, the detection of a concomitant complicated neoplasm, required identification of both ureters due the anatomic doubt of its localization and to avoid them being injured. In conclusion, upon finding a casual crossed renal ectopia during an emergency surgery of sigma, we recommend the identification of the ureters to facilitate its location and to avoid any injury to the ureters.

“Basket weave technique” for medial patellofemoral ligament reconstruction: Clinical outcome of a prospective study

PubMed Central

Kodkani, Pranjal S

2016-01-01

Background: Bone tunneling and implants with rigid fixations for medial patellofemoral ligament (MPFL) reconstruction are known to compromise results and are avoidable, especially in skeletally immature subjects. This study was to assess if these deficiencies were overcome with the technique devised by the author which avoids implants and bone tunnels. Results were assessed for complication rate and outcome. Materials and Methods: Fifty six knees of recurrent lateral patellar dislocation were treated in the past 49 months by MPFL reconstruction. Thirty nine were female and 17 male knees. The mean age was 20.6 years (range 9-48 years). Mean followup was 26 months. Five knees had previously failed stabilization procedures. Thirty one cases had Dejours Type A or B and 12 had Type C trochlear dysplasia. Arthroscopy was performed for associated injuries and loose bodies. Seven knees required loose body removal. Five knees underwent lateral retinacular release. Four knees had tibial tuberosity transfer. One knee had an associated anterior cruciate ligament reconstruction. An anatomical MPFL reconstruction was performed using hamstring autograft without the need for intraoperative fluoroscopy. Only soft tissue fixation was necessary with this newly devised technique and suturing. A rapid rehabilitation protocol was implemented with monthly followup until normalcy and 6 monthly thereafter. Results: All achieved full range of motion and normal mediolateral stability. There was no recurrence of dislocation. No major surgery related complications. One patella fracture at 8 months was due to a fall developed terminal restriction of flexion. Those in sports could return to their sporting activities (Tegner 1–9). Cases with osteochondral fractures had occasional pain that subsided in 1 year. Mean Kujala score improved from 64.3 to 99.69 with KOOS score near normal in all. Conclusion: This new method of MPFL reconstruction gives excellent results. It avoids complications related to bone tunneling and implants. It is a safe, effective, reliable and reproducible technique. PMID:26952121

Blood donation, though safe, has a few potentially avoidable complications associated with it. They are important reasons for the failure of the donors to return for repeat donations. The aim of this study was to assess the frequency and identify the possible factors associated with increased risk of blood donation related complications so that they can be minimized. A prospective study was done over a period of four months in the blood bank of an Indian tertiary care hospital to record the donation related complications. Out of 7450 blood donations, total donation associated complications were 74, of which majority were vasovagal reactions (VVRs) (n=48), followed by venous hematomas (n=24) and arterial punctures (n=2). The incidence of VVRs was more, though not statistically significant, in females, replacement/repeat donors, donors between 21-30 y of age and who had a body-mass-index (BMI) of 18.5-24.9. VVRs were more common in April (p=0.002) and in those who donated 450ml of blood (p<0.001). Though hematomas were more frequent in females, voluntary donors, donors in age-group of 41-50, those with BMI<18.5 and in those who donated 350ml of blood, statistically significant association was seen only in repeat donors (p<0.001). Our study emphasizes that blood donation in our country has a complication rate of nearly 1%.

Child sexual abuse (CSA) is a global public health problem with major consequences for the individual child and society. An earlier Swedish study showed that the school nurses did not initially talk about nor mention CSA as one form of child abuse. For the child to receive adequate support, the disclosure is a precondition and is dependent on an available person prepared to listen. The aim of the study was to explore the ability of the school nurses to detect and support sexually abused children. It is a secondary analysis of focus group interviews with school nurses. Thematic analysis was performed. Results showed that the school nurses avoided addressing CSA due to arousal of strong emotions, ambivalence, and a complicated disclosure process. In order to detect CSA and support abused children, attentiveness of sexual abuse as a possible cause of physical and mental ill-health is crucial.

Calcium oxalate crystal related kidney injury in a patient receiving Roux-en Y hepaticojejunostomy due to gall bladder cancer.

Calcium oxalate nephropathy is rare in current practice. It was a common complication during jejunoileal bypass, but much less seen in modern gastric bypass surgery for morbid obesity. The major cause of it is enteric hyperoxaluria. We report on a patient here with acute kidney disease due to calcium oxalate nephropathy, rather than the conditions mentioned above. The male patient received a Roux-en Y hepaticojejunostomy and common bile duct drainage. In addition to enteric hyperoxaluria, chronic kidney disease related metabolic acidosis, chronic diarrhea related volume depletion, a high oxalate and low potassium diet, long term ascorbic acid intake and long term exposure to antibiotics, all predisposed him to having oxalate nephropathy. This is the first case with such conditions and we recommend that similarly diagnosed patients avoid all these predisposing factors, in order to avoid this rare disease and its undesired outcome.

The use of magnesium in lightweight lithium-ion battery packs

NASA Astrophysics Data System (ADS)

Neelameggham, Neale R.

2009-04-01

The analysis of recently announced battery packs for plug-in hybrid electric vehicles (PHEV) shows that the design of the series-parallel combinations is being over-complicated. The proven energy densities of lithium-ion cells from about 200 Wh/kg are being reduced to 90 Wh/kg. The majority of the weight increase seems to be for thermal management. Simpler battery pack designs based on electro-refining pot rooms using self-contained rectangular lithium-ion cells with air cooling inside of die-cast magnesium cell tanks would help avoid hauling dead weight in PHEV by providing considerable weight reduction.

This study examined the effectiveness of manipulation under ultrasound-guided brachial plexus block in patients with recalcitrant idiopathic frozen shoulder and diabetic secondary frozen shoulder (diabetic frozen shoulder). Forty-four idiopathic frozen shoulders and 10 diabetic frozen shoulders with failed conservative treatment for at least 3 months were included in this study. The manipulation was performed under ultrasound-guided brachial plexus block and visual analogue scale, range of motion, and Constant scores were measured before manipulation and at the last follow-up examination. No major complications were observed during the procedure. Sufficient improvement was not obtained in two patients during the procedure and to avoid complications, the procedure was discontinued and subsequently arthroscopic capsular release was performed. Visual analogue scale, range of motion towards all directions, and Constant scores were significantly improved after the manipulation in both the idiopathic frozen shoulder and diabetic frozen shoulder groups, however the diabetic group showed inferior results compared with those of the idiopathic group. This manipulation was effective and shortened the duration of symptoms in most of the idiopathic and diabetic frozen shoulders without major complications during the procedure. Diabetic frozen shoulder showed inferior clinical results and difficulty in recovery in range of motion, which indicated that diabetic frozen shoulder should be discussed as a different entity.

In patients with severe aortic stenosis, transcatheter aortic valve replacement (TAVR) improves survival when compared with nonsurgical therapy but with higher in-hospital and lifetime costs. Complications associated with TAVR may decrease with greater experience and improved devices, thereby reducing the overall cost of the procedure. Therefore, we sought to estimate the effect of periprocedural complications on in-hospital costs and length of stay of TAVR. Using detailed cost data from 406 TAVR patients enrolled in the Placement of Aortic Transcatheter Valve (PARTNER) I trial, we developed multivariable models to estimate the incremental cost and length of stay associated with specific periprocedural complications. Attributable costs and length of stay for each complication were calculated by multiplying the independent cost of each event by its frequency in the treatment group. Mean cost for the initial hospitalization was $79 619±40 570 ($50 891 excluding the valve); 49% of patients had ≥1 complication. Seven complications were independently associated with increased hospital costs, with major bleeding, arrhythmia, and death accounting for the largest attributable cost per patient. Renal failure and the need for repeat TAVR, although less frequent, were also associated with substantial incremental and attributable costs. Overall, complications accounted for $12 475 per patient in initial hospital costs and 2.4 days of hospitalization. In the PARTNER trial, periprocedural complications were frequent, costly, and accounted for ≈25% of non-implant-related hospital costs. Avoidance of complications should improve the cost-effectiveness of TAVR for inoperable and high-risk patients, but reductions in the cost of uncomplicated TAVR will also be necessary for optimal efficiency. http://www.clinicaltrials.gov.

Multiple techniques are used for repair in duodenal injury ranging from simple suture repair for low-grade injuries to pancreaticoduodenectomy for complicated high-grade injuries. Drains, both intraluminal and extraluminal, are placed variably depending on associated injuries and confidence with the repair. It is our contention that a simplified approach to repair will limit complications and mortality. The major complication of duodenal leak (DL) was the outcome used to assess methods of repair in this study. After early deaths from associated vascular injuries were excluded, patients with a penetrating duodenal injury admitted during a 19-year period ending in 2014 constituted the study population. A total of 125 patients with penetrating duodenal injuries were included. Overall, the leak rate was 8% with two duodenal-related mortalities. No differences were seen in patients who had a DL as compared with no leak with respect to demographics, injury severity, or admission variables. Patients with DL were more likely to have a major vascular injury (60% vs. 23%, p = 0.02) and a combined pancreatic injury (70% vs. 31%, p = 0.03). No differences were identified by repair technique, location, or grade of injury. DLs were more likely to have an extraluminal drain (90% vs. 45%, p = 0.008). Primary suture repair should be the initial approach considered for most injuries. Major vascular injuries and concomintant pancreatic injuries were associated with most leaks; therefore, adjuncts to repair including intraluminal drainage and pyloric exclusion should be considered on the initial operation. Extraluminal drains should be avoided unless required for associated injuries. Therapeutic/care management study, level IV.

Rescue strategies against non-steroidal anti-inflammatory drug-induced gastroduodenal damage.

2009-07-01

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed drugs worldwide, which attests to their efficacy as analgesic, antipyretic and anti-inflammatory agents as well as anticancer drugs. However, NSAID use also carries a risk of major gastroduodenal events, including symptomatic ulcers and their serious complications that can lead to fatal outcomes. The development of "coxibs" (selective cyclooxygenase-2 [COX-2] inhibitors) offered similar efficacy with reduced toxicity, but this promise of gastroduodenal safety has only partially been fulfilled, and is now dented with associated risks of cardiovascular or intestinal complications. Recent advances in basic science and biotechnology have given insights into molecular mechanisms of NSAID-induced gastroduodenal damage beyond COX-2 inhibition. The emergence of newer kinds of NSAIDs should alleviate gastroduodenal toxicity without compromising innate drug efficacy. In this review, novel strategies for avoiding NSAID-associated gastroduodenal damage will be described.

2013-07-01

Pseudomeningocele is an extradural cerebrospinal fluid collection arising from a dural defect, that may be congenital, traumatic, or more commonly as a result of postoperative complication. Majority of the postoperative pseudomeningoceles occurring after lumbar spine surgeries are small and resolve spontaneously. However, large pseudomeningoceles are rare and spontaneous resolution of such pseudomeningoceles has not been described. We report four cases of postoperative large lumbar pseudomeningoceles that presented as asymptomatic soft fluctuant swelling over the back which resolved spontaneously. We also reviewed the related literatures and operative records of these patients to find the possible mechanism of occurrence, their management, prevention, and reasons for spontaneous resolution. We conclude that nonoperative management under close observation can be employed for asymptomatic postoperative large lumbar pseudomeningoceles. Surgical exploration and repair should be reserved for symptomatic cases presenting with clinical features of intracranial hypotension, worsening neurology, external fistula or infection, thereby avoiding morbidity and potential complications associated with surgical treatment.

Background Surgical complications represent a significant cause of morbidity and mortality with the rate of major complications after inpatient surgery estimated at 3–17% in industrialised countries. The purpose of this review was to summarise experience with surgical checklist use and efficacy for improving patient safety. Methods A search of four databases (MEDLINE, CINAHL, EMBASE and the Cochrane Database of Controlled Trials) was conducted from 1 January 2000 to 26 October 2012. Articles describing actual use of the WHO checklist, the Surgical Patient Safety System (SURPASS) checklist, a wrong-site surgery checklist or an anaesthesia equipment checklist were eligible for inclusion (this manuscript summarises all but the anaesthesia equipment checklists, which are described in the Agency for Healthcare Research and Quality publication). Results We included a total of 33 studies. We report a variety of outcomes including avoidance of adverse events, facilitators and barriers to implementation. Checklists have been adopted in a wide variety of settings and represent a promising strategy for improving the culture of patient safety and perioperative care in a wide variety of settings. Surgical checklists were associated with increased detection of potential safety hazards, decreased surgical complications and improved communication among operating staff. Strategies for successful checklist implementation included enlisting institutional leaders as local champions, incorporating staff feedback for checklist adaptation and avoiding redundancies with existing systems for collecting information. Conclusions Surgical checklists represent a relatively simple and promising strategy for addressing surgical patient safety worldwide. Further studies are needed to evaluate to what degree checklists improve clinical outcomes and whether improvements may be more pronounced in particular settings. PMID:23922403

The extent, magnitude and technical equipment used for thyroid surgery has changed considerably in Germany during the last decade. The number of thyroidectomies due to benign goiter have decreased while the extent of thyroidectomy, nowadays preferentially total thyroidectomy, has increased. Due to an increased awareness of surgical complications the number of malpractice claims is increasing. In contrast to surgical databases the frequency of complications in malpractice claims reflects the individual impact of complications on the quality of life. In contrast to surgical databases unilateral and bilateral vocal fold palsy are therefore at the forefront of malpractice claims. As guidelines are often not applicable for the individual surgical expert review, the question arises which are the relevant criteria for the professional expert witness assessing the severity of the individual complication. While in surgical databases major complications after thyroidectomy, such as vocal fold palsy, hypoparathyroidism, hemorrhage and infections are equally frequent (1-3 %), in malpractice claims vocal fold palsy is significantly more frequent (50 %) compared to hypoparathyroidism (15 %), hemorrhage and infections (about 5 % each). To avoid bilateral nerve palsy intraoperative nerve monitoring has become of utmost importance for surgical strategy and malpractice suits alike. For surgical expert review documentation of individual risk-oriented indications, the surgical approach and postoperative management are highly important. Guidelines only define the treatment corridors of good clinical practice. Surgical expert reviews in malpractice suits concerning quality of care and causality between surgical management, complications and sequelae of complications are therefore highly dependent on the grounds and documentation of risk-oriented indications for thyroidectomy, intraoperative and postoperative surgical management.

Endovascular aortic repair (EVAR) has been shown to be a valid and minimally invasive alternative to open abdominal aortic aneurysm repair. A major shortcoming for EVAR is the need to submit patients to regular follow-up to detect potential complications such as endoleak, limb occlusion, aneurysm expansion, aneurysm rupture, infection, structural failure, and migration. In this case report, we describe an uncommon case of late type III endoleak due to complete detachment of the stent-graft main body segment from its suprarenal uncovered fixation stent. It was treated with a custom-made Relay(®) NBS Plus (Bolton Medical, Barcelona, Spain) thoracic stent graft which also provided extra suprarenal fixation of the thoracic stent graft in the proximal neck. The postoperative period was uneventful and a computed tomography scan 1 year later revealed proper positioning of the stent graft and no signs of endoleak. The successful strategy chosen to correct this complication was at the same time original and infrequent, and also avoided potential complications related to open surgical repair and general anesthesia.

Digestive complications related to the ingestion of magnetic foreign bodies in children are increasing, especially in Asia and North America. In France, several case reports have been reported since 2008. We conducted a retrospective multicentric study to evaluate the frequency of ingestion of magnet foreign bodies and to describe the complicated cases that have occurred in France over the last 5 years. We report 40 cases of which 60% were multiple magnet ingestions. Eighty-eight percent of the children of the group who had swallowed multiple magnets needed interventional management by endoscopy (33%) or surgery (58%). Only two children (12.5%) of the group who swallowed one magnet required removal. This problem is not uncommon in France (2% of the 1132 foreign bodies investigated in the Toulouse center over 5 years), which justifies clear information for healthcare professionals and caregivers in order to avoid potential intestinal complications. We suggest interventional management or very close monitoring in the cases of multiple magnet ingestion. Meanwhile, in the majority of confirmed cases of simple magnet ingestions, we propose home monitoring. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

[Pro: Epidural Analgesia Remains the Gold Standard for Abdominal and Thoracic Surgery].

PubMed

Listing, Hannah; Pöpping, Daniel

2018-04-01

Pain relief with epidural analgesia is superior compared to systemic opioid analgesia after major abdominal and thoracic surgery. It remains a safe procedure, as long as it is embedded in a concept covering the whole perioperative period. This includes the knowledge of the anesthesiologist how to operate the process of catheter insertion as well as to treat complications like the hypotension, associated with the application of epidural local anesthetics. A close postoperative monitoring by an acute pain service team is a responsible task and should be available 24/7. Despite the low incidence of complications, their consequences could be disastrous for patients. To avoid persisting neurological damage, standardized diagnostic procedures must be established and surgical intervention should be available within six hours if necessary. Non-analgetic benefits of epidural analgesia include reduced pulmonary complications like pneumonia and lower incidences for cardiac arrhythmia. Furthermore, perioperative mortality could be decreased by epidural analgesia. These effects should be considered as "add-on". The excellent pain relief is more than enough to recommend this method.

To assess process-of-care indicators and outcomes in acute pyelonephritis (APN) in a general hospital emergency department, and compare them between uncomplicaed and complicated APN. Retrospective study of consecutive patients discharged with a diagnosis of APN. We studied health processof- care indicators (percentage admitted, avoidable hospitalization, appropriate initial antibiotic therapy, urine and blood cultures) and outcomes (hospital length of stay [LOS], discharge from the emergency department, revisits, mortality, yields of microbiological tests ordered). A total of 529 cases (59% of them complicated) were included. Patients with uncomplicated APN were significantly younger on average (mean, 39 years) than patients with complicated APN (56 years). Escherichia coli was the most common pathogen identified, although the percentage of E coli infection was lower in patients with complicated APN (78%) than in patients with uncomplicated APN (95%). The rates of admission and orders for urine and blood cultures were significantly higher and hospital LOS was longer in the group with complicated APN. Moreover, these patients had even longer stays if the initial antibiotic therapy was inappropriate. Significantly more patients with uncomplicated APN were discharged from the emergency department. Sixty-one percent of patients with uncomplicated APN were admitted; 9% of these cases were considered avoidable hospitalizations. Complicated APN is diagnosed more often in older patients, and E coli infection causes a smaller proportion of these cases. Hospital LOS is longer in complicated APN and more urine and blood cultures are ordered. Patients with uncomplicated APN are more often discharged from the emergency department, although the number of avoidable hospitalizations seems high based on the rate found in this study.

Dangerous extracranial-intracranial anastomoses and supply to the cranial nerves: vessels the neurointerventionalist needs to know.

Transarterial embolization in the external carotid artery (ECA) territory has a major role in the endovascular management of epistaxis, skull base tumors, and dural arteriovenous fistulas. Knowledge of the potential anastomotic routes, identification of the cranial nerve supply from the ECA, and the proper choice of embolic material are crucial to help the interventionalist avoid neurologic complications during the procedure. Three regions along the skull base constitute potential anastomotic routes between the extracranial and intracranial arteries: the orbital, the petrocavernous, and the upper cervical regions. Branches of the internal maxillary artery have anastomoses with the ophthalmic artery and petrocavernous internal carotid artery (ICA), whereas the branches of the ascending pharyngeal artery are connected to the petrocavernous ICA. Branches of both the ascending pharyngeal artery and the occipital artery have anastomoses with the vertebral artery. To avoid cranial nerve palsy, one must have knowledge of the supply to the lower cranial nerves: The petrous branch of the middle meningeal artery and the stylomastoid branch of the posterior auricular artery form the facial arcade as the major supply to the facial nerve, and the neuromeningeal trunk of the ascending pharyngeal artery supplies the lower cranial nerves (CN IX-XII).

The aim of this study was to review the complication rate and profile associated with surgical fixation of acute midshaft clavicle fracture in a large cohort of patients treated in a level I trauma centre. We identified all patients who underwent surgical treatment of acute midshaft clavicle fracture between 2002 and 2010. The study group consisted of 138 fractures (134 patients) and included 107 men (78%) and 31 women (22%); the median age of 35 years (interquartile range (IQR) 24-45). The most common mechanism of injury was a road traffic accident (78%). Sixty percent (n=83) had an injury severity score of ≥15 indicating major trauma. The most common fracture type (75%) was simple or wedge comminuted (2B1) according to the Edinburgh classification. The median interval between the injury and operation was 3 days (IQR 1-6). Plate fixation was performed in 110 fractures (80%) and intramedullary fixation was performed in 28 fractures (20%). There were 85 men and 25 women in the plate fixation group with median age of 35 years (IQR 25-45) There were 22 men and six women in the intramedullary fixation group with median age of 31 years (IQR 24-42 years). Statistical analysis was performed using independent sample t test, Mann Whitney test, and Chi square test. Significant P-value was <0.05. The overall incidence of complication was 14.5% (n=20). The overall nonunion rate was 6%. Postoperative wound infection occurred in 3.6% of cases. The incidence of complication associated with plate fixation was 10% (11 of 110 cases) compared to 32% associated with intramedullary fixation (nine of 28 cases; P=0.003). Thirty-five percent of complications were related to inadequate surgical technique and were potentially avoidable. Symptomatic hardware requiring removal occurred in 23% (n=31) of patients. Symptomatic metalware was more frequent after plate fixation compared to intramedullary fixation (26% vs 7%, P=0.03). Intramedullary fixation of midshaft clavicle fracture is associated with a higher incidence of complications. Plate fixation is associated with a higher rate of symptomatic metalware requiring removal compared to intramedullary fixation. Approximately one in three complications may be avoided by attention to adequate surgical technique. Copyright © 2016 Elsevier Ltd. All rights reserved.

Port removal is usually a straightforward procedure delegated to trainees. However, some port removals are complicated by central venous catheter (CVC) fragmentation, a challenge for even experienced surgeons. This study aimed to determine the incidence of, and risk factors for, complicated port removal in children. A single-centre study assessed the outcome of removal for all paediatric ports inserted from 1996 to 2012. Data were recorded detailing patient, insertion, device and removal characteristics. Risk factors for complicated removals were scrutinised using Chi-square tests; p < 0.05 significant. Of 628 ports inserted from 1996 to 2012, 443 were subsequently removed at the same centre. 8/443 (1.8%) removals were complicated by CVC fragmentation, a median of 3.3 (2.4-3.9) years after insertion. Of complicated cases, 8/8 underwent formal neck dissection, 3/8 intravascular dissection, and 1/8 endovascular retrieval. 2/8 cases have retained intravascular CVC fragments. Risk factors for complication were CVC caliber <6Fr (p < 0.001) and use duration >2 years (p < 0.001). Greatest care and senior supervision should be ensured when removing ports with CVC caliber <6Fr and/or >2 years since insertion. However, complications also occur with larger CVCs or after shorter durations. Therefore, the key to avoiding complicated port removal may simply be: preparation, preparation, neck preparation.

This study aims to measure the economic costs of maternal complication and to understand household coping strategies for financing maternal healthcare cost. A household survey of the 706 women with maternal complication, of whom 483 had normal delivery, was conducted to collect data at 6 weeks and 6 months post-partum. Data were collected on socio-economic information of the household, expenditure during delivery and post-partum, coping strategies adopted by households and other related information. Despite the high cost of health care associated with maternal complications, the majority of families were capable of protecting consumption on non-health items. Around one-third of households spent more than 20% of their annual household expenditure on maternal health care. Almost 50% were able to avoid catastrophic spending because of the coping strategies that they relied on. In general, households appeared resilient to short-term economic consequences of maternal health shocks, due to the availability of informal credit, donations from relatives and selling assets. While richer households fund a greater portion of the cost of maternal health care from income and savings, the poorer households with severe maternal complication resorted to borrowing from local moneylenders at high interest, which may leave them vulnerable to financial difficulties. Financial protection, especially for the poor, may benefit households against economic consequences of maternal complication. © 2015 John Wiley & Sons Ltd.

Abdominoplasty is one of the most commonly performed cosmetic operative procedures. Few large studies have examined outcomes of cosmetic abdominoplasty in a community setting. The authors explored postoperative outcome and the preoperative and intraoperative factors that may contribute to these complications. A retrospective review of consecutive patients undergoing abdominoplasty over an 11-year period was performed. Baseline patient demographics, intraoperative technique, and postoperative outcomes were recorded. Preoperative and intraoperative characteristics were analyzed to determine characteristics that predispose patients to complications and undesirable outcomes. The 1008 study patients underwent either a full or modified abdominoplasty with a total complication rate of 32.6 percent. The most common complication was seroma (15.4 percent). Liposuction of the abdominal flap was performed in 469 patients (46.5 percent) and liposuction of the flanks was performed in 555 patients (55.1 percent). Chi-square analysis followed by logistic regression revealed that liposuction of the flanks and abdomen was independently associated with seroma formation in addition to major and minor complications (p < 0.05). Seroma formation following abdominoplasty is the most common complication. Concomitant liposuction of the flanks and abdomen with the addition of aggressive undermining leads to higher seroma rates. This association is likely multifactorial and may be secondary to increased resorptive demands placed on the abdominal lymphatics in the setting of greater dead space and larger fluid shifts as a result of liposuction. To reduce seroma rates, surgeons should avoid aggressive liposuction and undermining, particularly in high-risk patients.

Purpose. Avoidance of nontarget microsphere deposition via hepatoenteric anastomoses is essential to the safety of yttrium-90 radioembolization (RE). The hepatic hilar arterial network may remain partially patent after coil embolization of major arteries, resulting in persistent risk. We retrospectively reviewed cases where n-butyl cyanoacrylate (n-BCA) glue embolization was used to facilitate endovascular hepatic arterial skeletonization before RE. Methods. A total of 543 RE procedures performed between June 2004 and March 2012 were reviewed, and 10 were identified where n-BCA was used to embolize hepatoenteric anastomoses. Arterial anatomy, prior coil embolization, and technical details were recorded. Outcomes were reviewed to identifymore » subsequent complications of n-BCA embolization or nontarget RE. Results. The rate of complete technical success was 80 % and partial success 20 %, with one nontarget embolization complication resulting in a minor change in treatment plan. No evidence of gastrointestinal or biliary ischemia or infarction was identified, and no microsphere-related gastroduodenal ulcerations or other evidence of nontarget RE were seen. Median volume of n-BCA used was <0.1 ml. Conclusion. n-BCA glue embolization is useful to eliminate hepatoenteric networks that may result in nontarget RE, especially in those that persist after coil embolization of major vessels such as the gastroduodenal and right gastric arteries.« less

Lymphogranuloma venereum (LGV) is a sexually transmitted infectious disease caused by serovars L1, L2 and L3 of Chlamydia trachomatis. The initial presentation is usually a painless ulcerated papule on the genitalia or distal proctitis. The progression of the infection can lead to major complications: rectal strictures, intestinal obstruction or perforation. We present five cases of LGV proctitis as the initial presentation of the disease. All patients were male, mean age 44.6 years, with positive serology to human immunodeficiency virus (HIV) and promiscuous men who have sex with men (MSM).The initial diagnosis was made by rectosigmoidoscopy indicated for pain and anal discharge. All cases were confirmed by polymerase chain reaction technique in rectal tissue. Endoscopic images obtained showed a great variety of rectal lesions, from mild erythema of the mucosa and ulcers to deep ulcers with elevated borders and purulent exudate. All cases were resolved after treatment with doxycycline for 3 weeks. It emphasizes the importance of suspecting this re-emerging disease in patients with risk factors (HIV and MSM), with the aim of early treatment and to avoid major complications.

A modified intraoral and extraoral approach osteotomy for the prominent mandibular angle.

2017-08-01

A prominent mandibular angle (PMA) is a relatively common condition in Asians, and surgeons typically use the intraoral approach to treat it. However, the approach can have many drawbacks due to the limited operative field and view. The procedures of osteotomy are not easily manipulated, and an exact resection is difficult. In addition, some major complications can easily occur. This article presents a modified osteotomy method for the PMA that avoids these disadvantages and makes the procedure easier to execute. Four modifications of the procedures have been made: 1. The addition of a small extraoral incision in the auriculocephalic sulcus behind the earlobe; 2. A modest reduction in both the intraoral incision length and excessive mouth traction; 3. The use of a reciprocating saw through the extraoral incision tunnel to simplify the operative procedure; and 4. Extraction of sustained-suction drains from the extraoral incision. Postoperatively, all patients were followed up and administered the validated satisfaction questionnaire and the Patient Scar Assessment Questionnaire. From June 2010 to June 2015, 46 patients with a PMA underwent surgery using this method. All patients were satisfied with the esthetic results. The majority of patients could not feel an objectionable jaw line or bony step (86.9%), visible deformity (97.8%) or bony regrowth (95.6%). All patients noted a positive psychosocial influence. All patients perceived the overall appearance of their extraoral scar to be "good" or "excellent." Forty-five (97.8%) were "not at all" self-conscious of their scar. The overall complication rate was 6.5%, and no major complication was seen. The described method for the surgical treatment of PMA is a simple and safe procedure with fewer complications. The procedure is easy to perform, consumes less time, and can help resect the PMA accurately and easily. Copyright © 2017 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

At some academic hospitals, medical procedure services are being developed to provide supervision for residents performing bedside procedures in hopes of improving patient safety and resident education. There is limited knowledge of the impact of such services on procedural complication rates and resident procedural training opportunities. To determine the impact of a medical procedure service (MPS) on patient safety and resident procedural training opportunities. Retrospective cohort analysis comparing characteristics and outcomes of procedures performed by the MPS versus the primary medical service. Consecutive adults admitted to internal medicine services at a large academic hospital who underwent a bedside medical procedure (central venous catheterization, thoracentesis, paracentesis, lumbar puncture) between 1 July 2010 and 31 December 2011. The primary outcome was a composite rate of major complications. Secondary outcomes included resident participation in bedside procedures and use of "best practice" safety process measures. We evaluated 1,707 bedside procedures (548 by the MPS, 1,159 by the primary services). There were no differences in the composite rate of major complications (1.6 % vs. 1.9 %, p = 0.71) or resident participation in bedside procedures (57.0 % vs. 54.3 %, p = 0.31) between the MPS and the primary services. Procedures performed by the MPS were more likely to be successfully completed (95.8 % vs. 92.8 %, p = 0.02) and to use best practice safety process measures, including use of ultrasound guidance when appropriate (96.8 % vs. 90.0 %, p = 0.0004), avoidance of femoral venous catheterization (89.5 vs. 82.7 %, p = 0.02) and involvement of attending physicians (99.3 % vs. 57.0 %, p < 0.0001). Although use of a MPS did not significantly affect the rate of major complications or resident opportunities for training in bedside procedures, it was associated with increased use of best practice safety process measures.

Unable to comprehend the finality and consequences of the loss, they resort to excessive avoidance of reminders of the loss as they are tossed helplessly on waves of intense emotion. People with complicated grief need help, and clinicians need to know how to recognize the symptoms and how to provide help. This paper provides a framework to help clinicans understand bereavement, grief, and mourning. Evidence-based diagnostic criteria are provided to help clinicians recognize complicated grief, and differentiate it from depression as well as anxiety disorder.

Hospital readmission after major thoracic surgery has a marked effect on health care delivery, particularly in the era of value-based reimbursement. We sought to investigate the additive impact of comorbidity and postoperative complications on the risk of readmission after thoracic lobectomy. We queried the Nationwide Readmission Database of the Healthcare Cost and Utilization Project between 2010 and 2014 for discharges after pulmonary lobectomy with a primary diagnosis of lung cancer. We compared 90-day all-cause readmission rates across the presence of Elixhauser comorbidities and postoperative complications. Adjusted logistic and linear regression, accounting for patient and hospital factors were used to calculate the mean change in readmission rate by the number of comorbidities and postoperative complications. A total of 87,894 patients undergoing pulmonary lobectomies were identified during the study period, of whom 15,858 (18.0%) were readmitted for any cause within 90 days of discharge. After adjusting for other factors, each additional comorbidity and postoperative complication were associated with a 2.0% and 2.7% increased probability of readmission, respectively (both P < .0001). Patients with a low burden of low comorbidities were readmitted more frequently for postoperative complications, while those with a high burden of comorbidities were readmitted more frequently for chronic disease. Among patients with the lowest risk profile, there was an 11.7% readmission rate. Adjusting for other factors, each additional comorbidity and complication increased this rate by approximately 2.0% and 2.7%, respectively. These results demonstrate that the avoidance of postoperative complications may represent an effective mechanism for decreasing readmissions after thoracic surgery. Copyright © 2018 Elsevier Inc.

2012-06-20

Open surgery is still the main treatment of complex abdominal aortic aneurysm. Nevertheless, this approach is associated with major complications and high mortality rate. Therefore the fenestrated endograft has been used to treat the juxtarenal aneurysms. Unfortunately, no randomised controlled study is available to assess the efficacy of such devices. Moreover, the costs are still prohibitive to generalise this approach. Alternative treatments such as chimney or sandwich technique are being evaluated in order to avoid theses disadvantages. The aim of this paper is to present the endovascular approach to treat juxtarenal aneurysm and to emphasize that this option should be used only by highly specialized vascular centres.

Prevention of infection in war chest injuries.

Romanoff, H

1975-01-01

Infection is a major complication of military chest injuries. In a series of 142 wounded, infectious complications occurred in 7 (4.9%). Factors influencing the incidence of infection are evaluated. In this group of injuries, 81 patients were admitted soon after wounding. The intrathoracic damage was severe, due to penetration of metallic fragment. The hemothorax was treated by immediate intercostal drainage. Immediate thoracotomy was performed in 10 patients and late thoractomy in 15. One patient developed a lung abscess and 5 patients had infection following thoracotomy (7.4%). Another 61 wounded patients had been first managed in a forward hospital, including three with thoractomy for massive bleeding. Two, not in a forward hospital, had a bullet removed from the lung. Upon admission to this hospital, intercostal drains were inserted when needed and four patients underwent thoracotomy. Larger wounds were debrided in 24 patients. Late thoracotomy was perfromed in seven. Chronic empyema developed in one patient after pneumonectomy performed at the field hospital, resulting in a resuscitation or infection rate of less than 2%. Factors contributing to a low infection rate were: early drainage of hemothoraces and wide debridement of larger wounds with delayed closure and avoidance of thoracotomy as primary treatment. Resection of lung tissue was avoided. Thoraco-abdominal injuries were treated separately. The clotted hemothorax was immediately evacuated. Prolonged antibiotic therapy was usually indicated.

Malnutrition is associated with alcoholic liver disease (ALD) and related complications such as hepatic encephalopathy and increased rate of infections. Avoidance of prolonged fasting and overly restrictive diets is important to avoid poor nutrition. Adequate intake of calories, protein, and micronutrients via frequent small meals and evening supplements and/or enteral and parenteral nutrition when indicated has been associated with reduced mortality and morbidity in patients with ALD. Modification of protein/fat sources and composition in addition to probiotic supplementation are promising interventions for decreased progression of ALD and its complications.

Perioperative goal-directed therapy (PGDT) has been demonstrated to improve postoperative outcomes and reduce the length of hospital stays. The objective of our analysis was to evaluate the cost of complications, derived from French hospital payments, and calculate the potential cost savings and length of hospital stay reductions. The billing of 2388 patients who underwent scheduled high-risk surgery (i.e. major abdominal, gynaecologic, urological, vascular, and orthopaedic interventions) over three years was retrospectively collected from three French hospitals (one public-teaching, one public, and one private hospital). A relationship between mortality, length of hospital stays, cost/patient, and severity scores, based mainly on postoperative complications but also on preoperative clinical status, were analysed. Statistical analysis was performed using Student's t-tests or Wilcoxon tests. Our analyses determined that a severity score of 3 or 4 was associated with complications in 90% of cases and this represented 36% of patients who, compared with those with a score of 1 or 2, were associated with significantly increased costs (€ 8205±3335 to € 22,081±16,090; P<0.001, delta of € 13,876) and a prolonged length of hospital stay (mean of 10 to 27 days; P<0.001, delta of 17 days). According to estimates for complications avoided by PGDT, there was a projected reduction in average healthcare costs of between € 854 and € 1458 per patient and a reduction in total hospital bed days from 1755 to 4423 over three years. Based on French National data (47,000 high risk surgeries per year), the potential financial savings ranged from € 40M to € 68M, not including the costs of PGDT and its implementation. Our analysis demonstrates that patients with complications are significantly more expensive to care for than those without complications. In our model, it was projected that implementing PGDT during high-risk surgery may significantly reduce healthcare costs and the length of hospital stays in France while probably improving patient access to care and reducing waiting times for procedures.

Fashioning a defunctioning stoma is common when performing an anterior resection for rectal cancer in order to avoid and mitigate the consequences of an anastomotic leakage. We investigated the permanent stoma prevalence, factors influencing stoma outcome and complication rates following stoma reversal surgery. Patients who had undergone an anterior resection for rectal cancer between 2007 and 2013 in the northern healthcare region were identified using the Swedish Colorectal Cancer Registry and were followed until the end of 2014 regarding stoma outcome. Data were retrieved by a review of medical records. Multiple logistic regression was used to evaluate predefined risk factors for stoma permanence. Risk factors for non-reversal of a defunctioning stoma were also analysed, using Cox proportional-hazards regression. A total of 316 patients who underwent anterior resection were included, of whom 274 (87%) were defunctioned primarily. At the end of the follow-up period 24% had a permanent stoma, and 9% of patients who underwent reversal of a stoma experienced major complications requiring a return to theatre, need for intensive care or mortality. Anastomotic leakage and tumour Stage IV were significant risk factors for stoma permanence. In this series, partial mesorectal excision correlated with a stoma-free outcome. Non-reversal was considerably more prevalent among patients with leakage and Stage IV; Stage III patients at first had a decreased reversal rate, which increased after the initial year of surgery. Stoma permanence is common after anterior resection, while anastomotic leakage and advanced tumour stage decrease the chances of a stoma-free outcome. Stoma reversal surgery entails a significant risk of major complications. Colorectal Disease © 2017 The Association of Coloproctology of Great Britain and Ireland.

Proper packaging for food and no-food products to avoid injuries.

This paper aims to present data on proper packaging for food and no-food products to avoid injuries. Data collection was made from the Susy Safe data base and the results of the literature research. Fatal and near fatal foreign bodies injuries may occur at any age, however it is a particular problem for infants and young children due to a variety of predisposing factors. Safety packaging is therefore a landmark and a model for accident prevention. Taken the lack of researches and specificity on this subject, it is warmly suggested that a broader and deeper exploration, both at customer's and public health levels, has to be made, highlighting major risks and complications. Packaging classes are extremely composite, therefore accuracy in data registry must be achieved, since from a preventive point of view it is basilar not only knowing the nature of the foreign body but also having information on its origin.

Fuzzy logic path planning system for collision avoidance by an autonomous rover vehicle

NASA Technical Reports Server (NTRS)

Murphy, Michael G.

1993-01-01

The Space Exploration Initiative of the United States will make great demands upon NASA and its limited resources. One aspect of great importance will be providing for autonomous (unmanned) operation of vehicles and/or subsystems in space flight and surface exploration. An additional, complicating factor is that much of the need for autonomy of operation will take place under conditions of great uncertainty or ambiguity. Issues in developing an autonomous collision avoidance subsystem within a path planning system for application in a remote, hostile environment that does not lend itself well to remote manipulation by Earth-based telecommunications is addressed. A good focus is unmanned surface exploration of Mars. The uncertainties involved indicate that robust approaches such as fuzzy logic control are particularly appropriate. Four major issues addressed are (1) avoidance of a fuzzy moving obstacle; (2) backoff from a deadend in a static obstacle environment; (3) fusion of sensor data to detect obstacles; and (4) options for adaptive learning in a path planning system. Examples of the need for collision avoidance by an autonomous rover vehicle on the surface of Mars with a moving obstacle would be wind-blown debris, surface flow or anomalies due to subsurface disturbances, another vehicle, etc. The other issues of backoff, sensor fusion, and adaptive learning are important in the overall path planning system.

Focus on migrants with type 2 diabetes mellitus in European Countries.

Testa, Roberto; Bonfigli, Anna Rita; Genovese, Stefano; Ceriello, Antonio

2016-04-01

The prevalence of type 2 diabetes mellitus, one of the major causes of morbility and mortality in Europe, is increasing in all European countries. Diabetes is not distributed equally among all population groups, as higher incidence, appearance of complications, and different mortality rates have been observed among migrants and the native population. These differences may be due to genetic profiles, lifestyle, and utilization of the health care system in different ways. Taking into account that the quantity of migrants is nowadays increasing, mainly in the southern part of Europe, the knowledge of diabetes in migrants through a better collection of data is necessary, considering that few limited epidemiological studies have evaluated the importance of this problem in EU countries. A special effort in developing a comprehensive management for native and immigrant populations in order to prevent and cure diabetes should be mandatory. This activity could be helpful to limit the incidence of future diabetes complications and to avoid the consequent burden of the health care system along with a control on its costs. It is clear that diabetes complication prevention is essential for long-term sustainability of the health care system.

Epidemiology, Etiology, Diagnosis, and Management of Placenta Accreta

Garmi, Gali; Salim, Raed

2012-01-01

Placenta accreta is a severe pregnancy complication and is currently the most common indication for peripartum hysterectomy. It is becoming an increasingly common complication mainly due to the increasing rate of cesarean delivery. Main risk factor for placenta accreta is a previous cesarean delivery particularly when accompanied with a coexisting placenta previa. Antenatal diagnosis seems to be a key factor in optimizing maternal outcome. Diagnosis can be achieved by ultrasound in the majority of cases. Women with placenta accreta are usually delivered by a cesarean section. In order to avoid an emergency cesarean and to minimize complications of prematurity it is acceptable to schedule cesarean at 34 to 35 weeks. A multidisciplinary team approach and delivery at a center with adequate resources, including those for massive transfusion are both essential to reduce neonatal and maternal morbidity and mortality. The optimal management after delivery of the neonate is vague since randomized controlled trials and large cohort studies are lacking. Cesarean hysterectomy is probably the preferable treatment. In carefully selected cases, when fertility is desired, conservative management may be considered with caution. The current review discusses the epidemiology, predisposing factors, pathogenesis, diagnostic methods, clinical implications and management options of this condition. PMID:22645616

Colonic diverticular disease. Treatment and prevention.

2015-12-01

Diverticular disease represents the most common disease affecting the colon in the Western world. Most cases remain asymptomatic, but some others will have symptoms or develop complications. The aims of treatment in symptomatic uncomplicated diverticular disease are to prevent complications and reduce the frequency and intensity of symptoms. Fibre, probiotics, mesalazine, rifaximin and their combinations seem to be usually an effective therapy. In the uncomplicated diverticulitis, outpatient management is considered the optimal approach in the majority of patients, and oral antibiotics remain the mainstay of treatment. Admission to hospital and intravenous antibiotic are recommended only when the patient is unable to intake food orally, affected by severe comorbidity or does not improve. However, inpatient management and intravenous antibiotics are necessary in complicated diverticulitis. The role of surgery is also changing. Most diverticulitis-associated abscesses can be treated with antibiotics and/or percutaneous drainage and emergency surgery is considered only in patients with acute peritonitis. Finally, patient related factors, and not the number of recurrences, play the most important role in selecting recipients of elective surgery to avoid recurrences.

Very premature delivery is a major cause of infant morbidity and mortality. Obesity, diabetes and pregnancy hypertension are known risk factors for pregnancy complications. The study aimed to scrutinize differences of pregnancy complications in a cohort of very premature deliveries compared to a national group. In a multicenter study performed between January 2009 and December 2010 including 1,577 very low birth weight (VLBW) infants, we compared parental reported pregnancy problems of VLBW infants with a national cohort (KIGGS). We compared reported pregnancy complications to reasons for premature delivery and neonatal outcome within the group of VLBW infants. While parents of the national cohort reported pregnancy-induced hypertension in 8 %, parents of VLBW infants reported this complication more frequently (27 %). Mothers of the national cohort were significantly younger (1 year), suffered less from obesity, anaemia, diabetes. Regression analysis showed that hypertension (OR = 5.11) and advanced maternal age (OR = 1.03) increased the risk for premature birth. Women with hypertension were likely to experience a clinically indicated premature delivery, had more VLBW infants with a moderate growth restriction, but less multiples and their infants had less intraventricular haemorrhages grade 3 or 4. Otherwise, neonatal outcome was correlated with gestational age but not with the pregnancy complications diabetes, hypertension or obesity. Premature birth seems to be correlated to gestational hypertension and associated problems in about ¼ of VLBW infants. Further studies should focus on preventing and treating gestational hypertension to avoid premature delivery and associated neonatal morbidity.

Operative colonoscopic endoscopy.

1992-01-01

There are several conditions where operative colonoscopy is useful. Acute colonic pseudo-obstruction or Ogilvie's syndrome is characterized by a acute distension of the colon. Although medical management may be sufficient in many cases, endoscopic decompression must be performed when colonic distension is greater than 12 cm. Insertion of decompression tube to avoid rapid recurrence seems to be adequate. In case of massive lower intestinal hemorrhage, colonoscopy seems to be more accurate than mesenteric angiography. Such endoscopic examination requires an experienced endoscopist. Colonoscopic polypectomy has become the standard method for removal of colonic polyps. Factors influencing the rate of complications have been studied. While the number of complications was very low, we have observed that all the major hemorrhages were immediate when the blended current was used, but delayed when the pure coagulation current was applied. Endoscopic laser photocavitation is a valuable palliative method treating rectal adenocarcinoma in well selected patients. Indeed, if the patients survive sufficiently long after initial therapy, it becomes increasingly difficult to achieve persistent palliation with laser therapy.

Blunt chest trauma can cause a wide variety of injuries including acute myocardial infarction (AMI). Although AMI due to coronary artery dissection caused by blunt chest trauma is very rare, it is associated with high morbidity and mortality. In the vast majority of patients with AMI, primary percutaneous coronary interventions (PCI) are performed to recanalize obstructed arteries, but PCI carries a substantial risk of hemorrhagic complications in the acute phase of trauma. We report a case of AMI due to right coronary artery (RCA) dissection caused by blunt chest trauma. The totally obstructed RCA was spontaneously recanalized with medical therapy. We could avoid primary PCI in the acute phase of blunt chest trauma because electrocardiogram showed early reperfusion signs. We performed an elective PCI in the subacute phase when the risk of bleeding subsided. Since the risk of severe hemorrhagic complications is greater in the acute phase of blunt chest trauma as compared with the late phase, deferring emergency PCI is reasonable if signs of recanalization are observed.

Over the last 10 years, there has been much development in the management of metastatic and osteoporotic vertebral compression fractures using vertebroplasty. This percutaneous image-guided interventional radiology procedure allows stabilization of a vertebral body by injection of an acrylic cement and frequently results in significant symptomatic relief. During cement polymerisation, an exothermic reaction may destroy adjacent tumor cells. Advances have been made to reduce complications from extravasation of cement in veins or surrounding soft tissues. Safety relates to experience but also to technical parameters: optimal cement radio-density, adequate digital fluoroscopy unit (single or bi-plane digital angiography unit), development of cements other than PMMA to avoid the risk of adjacent vertebral compression fractures. The rate of symptomatic relief from vertebroplasty performed for its principal indications (vertebral hemangioma, metastases, osteoporotic fractures) reaches 90-95%. The rate of complications is about 2% for metastases and less than 0.5% for osteoporotic fractures. Vertebroplasty plays a major role in the management of specific bone weakening vertebral lesions causing, obviating the need for kyphoplasty.

Primary total hip replacement for displaced subcapital fractures of the femur.

PubMed

Taine, W H; Armour, P C

1985-03-01

The management of displaced subcapital fracture of the hip is still controversial because of the high incidence of complications after internal fixation or hemiarthroplasty. To avoid some of these complications we have used primary total hip replacement for independently mobile patients over 65 years of age. A total of 163 cases, operated on over four years, have been reviewed. There were relatively more dislocations after operation for fracture than after total replacement for arthritis, and these were associated with a posterior approach to the hip. Only seven revision operations have been required. Of 57 patients who were interviewed an average of 42 months after replacement, 62% had excellent or good results as assessed by the Harris hip score. All the others had major systemic disease which affected their assessment. This inadequacy of current systems of hip assessment is discussed. It is concluded that total hip replacement is the best management for a selected group of patients with this injury, and that further prospective studies are indicated.

Off-Pump Versus On-Pump Coronary Artery Bypass Grafting-A Systematic Review and Analysis of Clinical Outcomes.

2018-04-04

Surgical coronary artery bypass grafting (CABG) is the standard of care for revascularization of left main or three-vessel coronary artery disease. The off-pump coronary artery bypass graft (OPCAB) procedure avoids the use of cardiopulmonary bypass. Theoretically, OPCAB may improve long-term outcomes by reducing the rates of perioperative myocardial injury, stroke, neurocognitive impairment, and cardiac-related mortality. Several high-quality clinical trials have been conducted since OPCAB became popular in the 1990s and have demonstrated no benefit of OPCAB over traditional CABG with respect to these outcomes despite favorable short-term reductions in transfusion requirements and other postoperative complications. Ultimately, OPCAB is associated with less effective myocardial revascularization and does not entirely prevent complications traditionally associated with cardiopulmonary bypass. This article reviews major high-quality trials of OPCAB versus traditional CABG with respect to both short- and long-term clinical outcomes. Copyright © 2018 Elsevier Inc. All rights reserved.

Evaluation of the blood supply to gastric conduits is critically important to avoid complications after esophagectomy. We began visual evaluation of blood flow using indocyanine green (ICG) fluorescent imaging in July 2015, to reduce reconstructive complications. In this study, we aimed to statistically verify the efficacy of blood flow evaluation using our simplified ICG method. A total of 285 consecutive patients who underwent esophagectomy and gastric conduit reconstruction were reviewed and divided into 2 groups: before and after introduction of ICG evaluation. The entire cohort and 68 patient pairs after propensity score matching (PS-M) were evaluated for clinical outcomes and the effect of visualized evaluation on reducing the risk of complication. The leakage rate in the ICG group was significantly lower than in the non-ICG group for each severity grade, both in the entire cohort (285 subjects) and after PS-M; the rates of other major complications, including recurrent laryngeal nerve palsy and pneumonia, were not different. The duration of postoperative ICU stay was approximately 1 day shorter in the ICG group than in the non-ICG group in the entire cohort, and approximately 2 days shorter after PS-M. Visualized evaluation of blood flow with ICG methods significantly reduced the rate of anastomotic complications of all Clavien-Dindo (CD) grades. Odds ratios for ICG evaluation decreased with CD grade (0.3419 for CD ≥ 1; 0.241 for CD ≥ 2; and 0.2153 for CD ≥ 3). Objective evaluation of blood supply to the reconstructed conduit using ICG fluorescent imaging reduces the risk and degree of anastomotic complication. Copyright © 2017 American College of Surgeons.

Nonoperative management (NOM) of blunt splenic injuries has been widely accepted, and the application of splenic artery embolization (SAE) has become an effective adjunct to NOM. However, complications do occur after SAE. In this study, we assess the factors leading to the major complications associated with SAE. Focusing on the major complications after SAE, we retrospectively studied patients who received SAE and were admitted to 2 major referral trauma centers under the same established algorithm for management of blunt splenic injuries. The demographics, angiographic findings, and factors for major complications after SAE were examined. Major complications were considered to be direct adverse effects arising from SAE that were potentially fatal or were capable of causing disability. There were a total of 261 patients with blunt splenic injuries in this study. Of the 261 patients, 53 underwent SAE, 11 (21%) of whom were noted to have 12 major complications: 8 cases of postprocedural bleeding, 2 cases of total infarction, 1 case of splenic abscess, and 1 case of splenic atrophy. Patients older than 65 years were more susceptible to major complications after SAE. Splenic artery embolization is considered an effective adjunct to NOM in patients with blunt splenic injuries. However, risks of major complications do exist, and being elderly is, in part, associated with a higher major complication incidence. Copyright © 2011 Elsevier Inc. All rights reserved.

Prevention and management of intraoperative crisis in VATS and open chest surgery: how to avoid emergency conversion.

PubMed

Safdie, Fernando M; Sanchez, Manuel Villa; Sarkaria, Inderpal S

2017-01-01

Video assisted thoracic surgery (VATS) has become a routinely utilized approach to complex procedures of the chest, such as pulmonary resection. It has been associated with decreased postoperative pain, shorter length of stay and lower incidence of complications such as pneumonia. Limitations to this modality may include limited exposure, lack of tactile feedback, and a two-dimensional view of the surgical field. Furthermore, the lack of an open incision may incur technical challenges in preventing and controlling operative misadventures leading to major hemorrhage or other intraoperative emergencies. While these events may occur in the best of circumstances, prevention strategies are the primary means of avoiding these injuries. Unplanned conversions for major intraoperative bleeding or airway injury during general thoracic surgical procedures are relatively rare and often can be avoided with careful preoperative planning, review of relevant imaging, and meticulous surgical technique. When these events occur, a pre-planned, methodical response with initial control of bleeding, assessment of injury, and appropriate repair and/or salvage procedures are necessary to maximize outcomes. The surgeon should be well versed in injury-specific incisions and approaches to maximize adequate exposure and when feasible, allow completion of the index operation. Decisions to continue with a minimally invasive approach should consider the comfort and experience level of the surgeon with these techniques, and the relative benefit gained against the risk incurred to the patient. These algorithms may be expected to shift in the future with increasing sophistication and capabilities of minimally invasive technologies and approaches.

Though a possible cause of late neurological deficits after posterior cervical reconstruction surgery was reported to be an iatrogenic foraminal stenosis caused not by implant malposition but probably by posterior shift of the lateral mass induced by tightening screws and plates, its clinical features and pathomechanisms remain unclear. The aim of this retrospective clinical review was to investigate the clinical features of these neurological complications and to analyze the pathomechanisms by reviewing pre- and post-operative imaging studies. Among 227 patients who underwent cervical stabilization using cervical pedicle screws (CPSs), six patients who underwent correction of cervical kyphosis showed postoperative late neurological complications without any malposition of CPS (ND group). The clinical courses of the patients with deficits were reviewed from the medical records. Radiographic assessment of the sagittal alignment was conducted using lateral radiographs. The diameter of the neural foramen was measured on preoperative CT images. These results were compared with the other 14 patients who underwent correction of cervical kyphosis without late postoperative neurological complications (non-ND group). The six patients in the ND group showed no deficits in the immediate postoperative periods, but unilateral muscle weakness of the deltoid and biceps brachii occurred at 2.8 days postoperatively on average. Preoperative sagittal alignment of fusion area showed significant kyphosis in the ND group. The average of kyphosis correction in the ND was 17.6° per fused segment (range 9.7°-35.0°), and 4.5° (range 1.3°-10.0°) in the non-ND group. A statistically significant difference was observed in the degree of preoperative kyphosis and the correction angles at C4-5 between the two groups. The diameter of the C4-5 foramen on the side of deficits was significantly smaller than that of the opposite side in the ND group. Late postoperative neurological complications after correction of cervical kyphosis were highly associated with a large amount of kyphosis correction, which may lead foraminal stenosis and enhance posterior drift of the spinal cord. These factors may lead to both compression and traction of the nerves, which eventually cause late neurological deficits. To avoid such complications, excessive kyphosis correction should not be performed during posterior surgery to avoid significant posterior shift of the spinal cord and prophylactic foraminotomies are recommended if narrow neuroforamina were evident on preoperative CT images. Regardless of revision decompression or observation, the majority of this late neurological complication showed complete recovery over time.

Our research objective was to estimate the characteristics of major depressive disorder and social adaptation of women displaced during the war in Croatia in the early 1990s. We aimed to establish the relationship between major depressive disorder and displacement and study its impact on the outcome of depression in order to improve treatment and avoid possible complications. A group of 20 women, 35 to 55 years of age, displaced some time during the 199l.-1995. war in Croatia were compared to 27 women of the same age but with no experience of exile. All the patients suffered from major depressive disorder based upon DSM-IV diagnostic criteria. The Hamilton Rating Scale for Depression, the Zung Self Rating Depression Scale and the Social Adaptation Self-evaluation Scale were used. The objective intensity of depression of the displaced significantly decreased over time but not their personal experience of depression. All depressed patients manifested poor social adaptation. Many aspects of social functioning remained poor even after the improvement of depressive disorder. Displacement characteristics were: the length of time spent in exile, the place, and the circumstances of displacement regarding the members of the family accompanying the displaced women. These characteristics significantly influenced the expression of their major depressive disorder as well as social functioning. Displaced persons/refugees are at high risk of developing depressive disorder. Recognition of all risk factors and early diagnosis of depressive disorder followed by appropriate treatment could decrease the risk of chronic and complicated depression as well as the risk of poor social adaptation.

Infections are still a major problem in the developing countries like Pakistan because of poor sewage disposal and economic restraints. Acute viral hepatitis like Aand E are not uncommon in pediatric age group because of unhygienic food handling and poor sewage disposal, but majority recovers well without any complications. Co-infections are rare occurrences and physicians need to be well aware while managing such conditions to avoid worst outcome. Co-infection with hepatitis Aand E is reported occasionally in the literature, however, other concurrent infections such as hepatitis A with Salmonellaand hepatotropic viruses like viral hepatitis B and C are present in the literature. Co-infections should be kept in consideration when someone presents with atypical symptoms or unusual disease course like this presented case. We report here a girl child who had acute hepatitis A and E concurrent infections and presented with hepatic encephalopathy and had worst outcome, despite all the supportive measures being taken.

To study if ultrasound-guided aspiration with ethanol sclerosis is a safe and effective treatment for endometriomas. We conducted a prospective study of 25 women with 27 endometriomas (two bilateral) measuring 4-10cm in diameter with no suspected malignancy, who underwent ultrasound-guided aspiration and ethanol sclerosis between August 2010 and July 2014. Patients were followed up by ultrasound at 6, 12, 24, and 36 months to identify rates of complication and recurrence. Clinical characteristics of the patients (age, history of infertility, previous surgery, and abdominal pain), the cysts (location, diameter, and volume) and the procedure (duration and complications) were recorded. Kaplan-Meier survival curves were used to analyze the recurrence rates by SPSS statistical software. The recurrence rate after sclerosis was 12%. The mean length of follow-up was 17 (SD 9.9) months. Although no major procedure-related complications were recorded, minor complications included three cases of low abdominal pain during the procedure (10.7%) and two cases of abdominal ethanol extravasation (7.1%). Ultrasound-guided aspiration and ethanol sclerotherapy are a safe and effective treatment for endometriomas measuring 4-10cm in diameter with no evidence of malignancy. This conservative treatment could possibly achieve a symptomatic cure while preserving healthy ovarian tissue, thereby improving fertility outcomes and avoiding early menopause.

The purpose of this study was to describe the indications for and technique of transjugular renal biopsy (TJRB) and evaluate the efficacy and complications of this method. We performed a retrospective review of 59 patients who underwent TJRB using the Quick-core needle biopsy system (Cook, Letchworth, UK) over a 4-year period. The indications for obtaining renal biopsy included acute renal failure, chronic renal failure, nephrotic syndrome, and proteinuria with or without other associated disease. Indications for the transjugular approach included coagulopathy, biopsy of a solitary kidney or essentially single functioning kidney, simultaneous renal and hepatic biopsy, morbid obesity, and failedmore » percutaneous biopsy. All but four cases were performed via the right internal jugular vein. The right, left, or both renal veins were cannulated in 41, 14, and 4 cases, respectively. Combined liver and renal biopsies were obtained in seven cases. Diagnostic biopsy specimens were obtained in 56 of 59 patients (95%). The number and size of tissue cores ranged from 1 to 9 mm and from 1 to 20 mm, respectively. The mean numbers of glomeruli per procedure on light microscopy and electron microscopy were 10.3 and 2.6, respectively. Specimens for immunohistology were acquired in 49 cases, of which 40 were adequate. Of the 56 successful TJRB procedures, 34 (61%) were associated with isolated capsular perforation (19), contained subcapsular leak (10), isolated collecting system puncture (1), and concurrent collecting system and capsular perforation (4). There was a significant increase in capsular perforation with six or more needle passes, although no significant correlation was seen between number of needle passes and complication. Six patients had minor complications defined as hematuria or loin pain. Seven patients developed major complications, of whom five received blood transfusion alone. Two required intervention: in one an arteriocalyceal fistula was embolized and the patient was temporarily dialyzed; the remaining patient required ureteric stenting. In conclusion, TJRB provides an adequate yield for diagnosis. Complication rates are relatively high, but patients are also at high risk from the conventional percutaneous approach. Patient selection and optimization are critical to avoid major complications.« less

Cervical, thoracic, thoracolumbar, and lumbar fractures associated with physiologic complete or incomplete spinal cord injuries frequently have severe soft-tissue injury as well as severe pain associated with the site or area of injury. Transcutaneous electrical neurostimulation has proved effective in the treatment of various causes of severe acute and chronic intractable pains. We applied this modality to a group of 20 patients who had acute spinal cord injuries and pain associated with severe, extensive soft-tissue injury. Its advantages include ease of application, lack of major complications, increased intestinal peristalsis, and avoidance of narcotic analgesic medications. It also produced significant (greater than 50%) pain relief in 75% of patients treated by transcutaneous electrical neurostimulation.

Takayasu's arteritis (TA) is a rare, chronic progressive pan-endarteritis involving the aorta and its main branches. Anesthesia for patients with TA is complicated by severe uncontrolled hypertension, end-organ dysfunction, stenosis of major blood vessels, and difficulties in monitoring arterial blood pressure. We present the successful anesthetic management of a 23-year-old woman having TA with bilateral subclavian and renal artery stenosis posted for emergency cesarean section by using the epidural volume extension technique, which offers the combined advantage of both spinal and epidural anesthesia and, at the same time, also avoids the need of sophisticated neurological monitors like EEG and transcranial Doppler.

Gundanna, Mukund I.; Miller, Larry E.; Block, Jon E.

2011-01-01

Background Open and minimally invasive lumbar fusion procedures have inherent procedural risks, with posterior and transforaminal approaches resulting in significant soft-tissue injury and the anterior approach endangering organs and major blood vessels. An alternative lumbar fusion technique uses a small paracoccygeal incision and a presacral approach to the L5-S1 intervertebral space, which avoids critical structures and may result in a favorable safety profile versus open and other minimally invasive fusion techniques. The purpose of this study was to evaluate complications associated with axial interbody lumbar fusion procedures using the Axial Lumbar Interbody Fusion (AxiaLIF) System (TranS1, Wilmington, North Carolina) in the postmarketing period. Methods Between March 2005 and March 2010, 9,152 patients underwent interbody fusion with the AxiaLIF System through an axial presacral approach. A single-level L5-S1 fusion was performed in 8,034 patients (88%), and a 2-level (L4-S1) fusion was used in 1,118 (12%). A predefined database was designed to record device- or procedure-related complaints via spontaneous reporting. The complications that were recorded included bowel injury, superficial wound and systemic infections, transient intraoperative hypotension, migration, subsidence, presacral hematoma, sacral fracture, vascular injury, nerve injury, and ureter injury. Results Complications were reported in 120 of 9,152 patients (1.3%). The most commonly reported complications were bowel injury (n = 59, 0.6%) and transient intraoperative hypotension (n = 20, 0.2%). The overall complication rate was similar between single-level (n = 102, 1.3%) and 2-level (n = 18, 1.6%) fusion procedures, with no significant differences noted for any single complication. Conclusions The 5-year postmarketing surveillance experience with the AxiaLIF System suggests that axial interbody lumbar fusion through the presacral approach is associated with a low incidence of complications. The overall complication rates observed in our evaluation compare favorably with those reported in trials of open and minimally invasive lumbar fusion surgery. PMID:25802673

On Voxel based Iso-Tumor Control Probabilty and Iso-Complication Maps for Selective Boosting and Selective Avoidance Intensity Modulated Radiotherapy.

PubMed

Kim, Yusung; Tomé, Wolfgang A

2008-01-01

Voxel based iso-Tumor Control Probability (TCP) maps and iso-Complication maps are proposed as a plan-review tool especially for functional image-guided intensity-modulated radiotherapy (IMRT) strategies such as selective boosting (dose painting) and conformal avoidance IMRT. The maps employ voxel-based phenomenological biological dose-response models for target volumes and normal organs. Two IMRT strategies for prostate cancer, namely conventional uniform IMRT delivering an EUD = 84 Gy (equivalent uniform dose) to the entire PTV and selective boosting delivering an EUD = 82 Gy to the entire PTV, are investigated, to illustrate the advantages of this approach over iso-dose maps. Conventional uniform IMRT did yield a more uniform isodose map to the entire PTV while selective boosting did result in a nonuniform isodose map. However, when employing voxel based iso-TCP maps selective boosting exhibited a more uniform tumor control probability map compared to what could be achieved using conventional uniform IMRT, which showed TCP cold spots in high-risk tumor subvolumes despite delivering a higher EUD to the entire PTV. Voxel based iso-Complication maps are presented for rectum and bladder, and their utilization for selective avoidance IMRT strategies are discussed. We believe as the need for functional image guided treatment planning grows, voxel based iso-TCP and iso-Complication maps will become an important tool to assess the integrity of such treatment plans.

The latissimus dorsi flap is a reliable and one of the most commonly used methods of both immediate and delayed breast reconstruction. Its disadvantage is the limited volume of transferred tissue. The authors present their experience with the use of extended latissimus dorsi flap associated with immediate fat grafting into the pectoralis and latissimus dorsi muscles for secondary breast reconstruction. From 2013 to 2016, 14 patients underwent secondary unilateral total breast reconstruction with extended latissimus dorsi flap associated with primary fat grafting into the pectoralis major and latissimus dorsi muscles. Fat was injected under visual control between muscle fibers. Fat injected into the pectoralis muscle formed an apparent bulging - autoprosthesis. Mean patient age was 48.2 years (range, 34 to 64 years). Mean injected fat volume was 86.4 ml (range, 50 to 160 ml) and majority of this volume was injected into the pectoralis muscle. All flaps healed uneventfully and no fat grafting-related complications were observed. The most common complication was donor site seroma, which occurred in 57.1%. Results of postoperative ultrasound examination were evaluated. Incidence and the size of oil cysts and fat necroses were significantly lower in muscular layer in comparison with the subcutaneous layer of the reconstructed breast. Immediate fat transfer into the pectoralis and latissimus dorsi muscle increases the breast volume during the reconstruction with extended latissimus dorsi flap avoiding implant-related complications when abdominal tissue is not available. Pectoralis and latissimus dorsi muscles were shown as reliable and safe recipients for fat grafting.

The self-expandable metallic stent (SEMS) is an excellent non-invasive tool for emergent bowel obstruction. This study was designed to evaluate the clinical usefulness of the SEMS for avoiding perioperative complications. We analyzed a total of 47 consecutive patients who had a bowel obstruction due to colorectal cancer at initial diagnosis between 2012 and 2017 from hospital records. Perioperative complications occurred in 30% (14/47) of patients. Univariate and multivariate logistic regression analyses identified an age of more than 75 years [p=0.037, OR=6.84 (95% CI=1.11-41.6)] and the absence of an SEMS treatment [p=0.028, OR=18.5 (95% CI=1.36-250.0)] as independent risk factors for perioperative complications. Pneumonia (12.7% (6/47)) was the most common complication. There were no pneumonia patients (0% (0/15)) who were treated with the SEMS. In contrast to patients with the non-SEMS treatment, 18.7% (6/32) of all patients and 35.7% (5/14) of elderly patients had pneumonia. The SEMS is a safe and effective treatment for avoiding perioperative complications, particularly pneumonia, and may be a crucial strategy in elderly patients with acute obstruction due to colorectal cancer.

Tanimoto, Ryuta; Cleary, Ryan C; Bagley, Demetrius H; Hubosky, Scott G

2016-03-01

Flexible and semirigid ureteroscopy (URS) are widely performed for the treatment of upper tract calculi and tumors. Ureteral avulsion is a rare, but devastating complication of endoscopic stone removal having multiple possible etiologies. Awareness and avoidance of this rare complication depend on identifying responsible mechanisms. This study examines the situations in which ureteral avulsion occurs as described anonymously in the Manufacturer and User facility Device Experience (MAUDE) database. The MAUDE database was systematically reviewed to account for all reported complications of flexible and semirigid URS. Keywords "ureteroscopy, injury, death, malfunction and other" were entered in the database and medical device reports were reviewed to capture any cases resulting in ureteral avulsion. Attention was paid to the type of ureteroscope involved and the mechanism for avulsion. A total of 104 entries were found detailing the reported complications of flexible and semirigid URS. Ureteral avulsion was clearly noted in six reports with flexible (2) and semirigid ureteroscopes (4). Potential mechanisms included locked deflection of a flexible ureteroscope (1), bunching of the distal bending rubber in a flexible ureteroscope (1), scabbard avulsion (3), and stone basketing (1). Although the incidence of ureteral avulsion cannot truly be determined from this study, some potentially novel mechanisms for this rare complication are observed. This may target future educational efforts to maximize awareness and avoidance of this complication.

Healthcare teams that frequently follow a bundle of evidence-based processes provide care with lower rates of morbidity. Few process bundles to improve surgical outcomes in hysterectomy have been identified. The purpose of this study was to investigate whether a bundle of 4 perioperative care processes is associated with fewer postoperative complications and readmissions for hysterectomies in the Michigan Surgical Quality Collaborative. A bundle of perioperative care process goals was developed retrospectively with 30-day peri- and postoperative outcome data from the Hysterectomy Initiative in Michigan Surgical Quality Collaborative. All benign hysterectomies that had been performed between January 2013 and January 2015 were included. Based on evidence of lower complication rates after benign hysterectomy, the following processes were considered to be the "bundle": use of guideline-appropriate preoperative antibiotics, a minimally invasive surgical approach, operative duration <120 minutes, and avoidance of intraoperative hemostatic agent use. Each process was considered present or absent, and the number of processes was summed for a bundle score that ranged from 0-4. Cases with a score of zero were excluded. Outcomes measured were rates of complications (any and major) and hospital readmissions, all within 30 days of surgery. Postoperative events that were considered a "major complication" included acute renal failure, cardiac arrest that required cardiopulmonary resuscitation, central line infection, cerebral vascular accident, death, deep vein thrombosis, intestinal obstruction, myocardial infarction, pelvic abscess, pulmonary embolism, rectovaginal fistula, sepsis, surgical site infection (deep and organ-space), unplanned intubation, ureteral obstruction, and ureterovaginal and vesicovaginal fistula. The outcome "any complication" included all those events already described in addition to blood transfusion within 72 hours of surgery, urinary tract infection, and superficial surgical site infection. Outcomes were adjusted for patient demographics, surgical factors, and hospital-level clustering effects. There were 16,286 benign hysterectomies available for analysis. Among all hysterectomies that were reviewed, 33.6% met criteria for all bundle processes; however, there was wide variation in the rate among the 56 hospitals in the study sample with 9.1% of cases at the lowest quartile and 60.4% at the highest quartile of hospitals that met criteria for all bundle processes. Overall, the rate of any complication was 6.8% and of any major complication was 2.3%. The rate of hospital readmissions was 3.6%. After adjustment for confounders, in cases in which all bundle criterion were met compared with cases in which all bundle criterion were not met, the rate of any complications increased from 4.3-7.8% (P<.001); major complications increased from 1.7-2.6% (P<.001), and readmissions increased from 2.6-4.1% (P<.001). After adjustment for confounders, hospitals with greater rates of meeting all 4 criteria were associated significantly with lower hospital-level rates of postoperative complications (P<.001) and readmissions (P<.001). This multiinstitutional evaluation reveals that reduced morbidity and readmission are associated with rates of bundle compliance. The proposed bundle is a surgical goal, which is not possible in every case, and there is significant variation in the proportion of cases meeting all 4 bundle processes in Michigan hospitals. Implementation of evidence-based process bundles at a healthcare system level are worthy of prospective study to determine whether improvements in patient outcomes are possible.

Spitz, L; Kirtane, J

1985-01-01

One hundred and six children undergoing antireflux surgery were studied; 41 were severely mentally retarded and 29 had reflux strictures. Although the eventual rate of success was 92%, 20 patients developed complications that required a second operation. Prolapse of the fundoplication into the mediastinum was the commonest complication (in seven patients), followed by intestinal obstruction (in five), and intractable fibrous oesophageal strictures (in five). The incidence of postoperative complications was highest in patients with mental retardation or oesophageal strictures. Referral of these patients for operation was invariably delayed, and earlier referral may have avoided many of the complications. PMID:4037858

A Case of Familial Mediterranean Fever Having Intermittent Leukopenia.

2018-03-01

Familial Mediterranean fever (FMF) is a genetically inherited autoinflammatory disorder characterized by inflammatory attacks and may result in amyloidosis as a severe complication. Elevation of acute phase reactants, including leukocytosis, is seen during attack periods. Here we describe a 13-year-old female patient with a very rare clinical presentation of FMF, who would experience FMF attacks when she did not regularly take her colchicine. During these attacks she had leukopenia and neutropenia instead of leukocytosis. The leukocyte count returned to normal when she continued the medication and avoided attacks. Ethnicity and clinical signs are important in leukopenic patientsand should be investigated for FMF to avoid unnecessary procedures and complications.

Unfavourable results with distraction in craniofacial skeleton

2013-01-01

Distraction osteogenesis has revolutionised the management of craniofacial abnormalities. The technique however requires precise planning, patient selection, execution and follow-up to achieve consistent and positive results and to avoid unfavourable results. The unfavourable results with craniofacial distraction stem from many factors ranging from improper patient selection, planning and use of inappropriate distraction device and vector. The present study analyses the current standards and techniques of distraction and details in depth the various errors and complications that may occur due to this technique. The commonly observed complications of distraction have been detailed along with measures and suggestions to avoid them in clinical practice. PMID:24501455

Prevention of Portal Hypertension: from Variceal Development to Clinical Decompensation

Vorobioff, Julio D.; Groszmann, Roberto J

2015-01-01

Pharmacological treatment of portal hypertension (PH) has been exclusively devoted to gastro-esophageal varices related events at different frameworks including prophylactic, emergency or preventive therapy. The goals of treatment are to avoid the first bleeding episode, stop active bleeding and prevent bleeding recurrence, respectively. The objective of pre-primary prophylaxis (PPP) is to avoid variceal development and therefore, it necessarily deals with cirrhotic patients at earlier stages of the disease. At these earlier stages, nonselective beta blocker (NSBB) have been ineffective in preventing the development of varices and other complications of PH. Therefore, treatment should not rely on NSBB. It is possible, that at these earlier stages, etiological treatment of liver disease itself could prevent the progression of PH. This review will focus mainly on early treatment of PH, because if successful, it may translate into histological-hemodynamic improvements, avoiding not only variceal development but also other PH related complications, such as ascites and porto-systemic encephalopathy (PSE). Moreover, the advent of new therapies may allow not only the prevention of the complications of PH, but also the chance of a substantial degree of regression in the cirrhotic process with the possible prevention of hepatocellular carcinoma (HCC).

Major postoperative complications are associated with a substantial increase in hospital costs. Trauma patients are known to have a higher rate of complications than the general surgery population. We used the National Surgical Quality Improvement Program (NSQIP) methodology to evaluate hospital costs, duration of stay, and payment associated with complications in trauma patients. Using NSQIP principles, patient data were collected for 512 adult patients admitted to the trauma service for > 24 hours at a Level 1 trauma center (2004-2005). Patients were placed in 1 of 3 groups: no complications (none), >or=1 minor complication (minor, eg, urinary tract infection), or >or=1 major complication (major, eg, pneumonia). Total hospital charges, costs, payment, and duration of stay associated with each complication group were determined from a cost-accounting database. Multiple regression was used to determine the costs of each type of complication after adjusting for differences in age, sex, new injury severity score, Glasgow coma scale score, maximum head abbreviated injury scale, and first emergency department systolic blood pressure. A total of 330 (64%) patients had no complications, 53 (10%) had >or= 1 minor complication, and 129 (25%) had >or= 1 major complication. Median hospital charges increased from $33,833 (none) to $81,936 (minor) and $150,885 (major). The mean contribution to margin per day was similar for the no complication and minor complication groups ($994 vs $1,115, P = .7). Despite higher costs, the patients in the major complication group generated a higher mean contribution to margin per day compared to the no complication group ($2,168, P < .001). The attributable increase in median total hospital costs when adjusted for confounding variables was $19,915 for the minor complication group (P < .001), and $40,555 for the major complication group (P < .001). Understanding the costs associated with traumatic injury provides a window for assessing the potential cost reductions associated with improved quality care. To optimize system benefits, payers and providers should develop integrated reimbursement methodologies that align incentives to provide quality care.

Adverse events related to blood transfusion

2014-01-01

The acute blood transfusion reactions are responsible for causing most serious adverse events. Awareness about various clinical features of acute and delayed transfusion reactions with an ability to assess the serious reactions on time can lead to a better prognosis. Evidence-based medicine has changed today's scenario of clinical practice to decrease adverse transfusion reactions. New evidence-based algorithms of transfusion and improved haemovigilance lead to avoidance of unnecessary transfusions perioperatively. The recognition of adverse events under anaesthesia is always challenging. The unnecessary blood transfusions can be avoided with better blood conservation techniques during surgery and with anaesthesia techniques that reduce blood loss. Better and newer blood screening methods have decreased the infectious complications to almost negligible levels. With universal leukoreduction of red blood cells (RBCs), selection of potential donors such as use of male donors only plasma and restriction of RBC storage, most of the non-infectious complications can be avoided.

Lung transplantation is now available for patients with cystic fibrosis (CF) and end-stage lung disease. While pulmonary graft function is often considered the major priority following transplantation, the nonpulmonary complications of this systemic disease also continue. We examined the GI complications in a cohort of patients who underwent transplantation. This was a retrospective study of all patients with CF who underwent transplantation between March 1988 and December 1998 in Toronto. Medical records were reviewed, and a short questionnaire was mailed to patients who were alive as of December 1998. There were 80 bilateral lung transplants performed in 75 patients. The questionnaire was distributed to 43 patients, of whom 27 patients (63%) responded. Pancreatic insufficiency requiring enzyme intake was evident in 72 of 75 patients (96%) at the time of surgery. Of three pancreatic-sufficient patients (4%), pancreatic insufficiency was diagnosed in two patients later. Biliary cirrhosis was diagnosed in three patients prior to transplantation. Distal intestinal obstruction syndrome (DIOS) was recorded for 15 patients (20%). Ten patients had a single episode, of which eight episodes occurred early in the postoperative period. Five patients had recurrent episodes. All were medically treated, except for two patients who underwent surgery. Other complications included cholecystitis (n = 3), mucocele of the appendix (n = 1), peptic ulcer disease (n = 3), and colonic carcinoma (n = 1). GI complications after lung transplantation are common in patients with CF, and attention should be paid to the risk for DIOS in the early postoperative period. Prevention and early medical treatment are important in order to avoid acute surgery. Close collaboration with the CF clinic, in order to diagnose and treat CF-related complications, is recommended.

Secondary analysis of the prospectively collected Veterans Affairs National Surgical Quality Improvement Program database. Determine rates of major medical complications, wound complications, and mortality among patients undergoing surgery for lumbar stenosis and examine risk factors for these complications. Surgery for spinal stenosis is concentrated among older adults, in whom complications are more frequent than among middle-aged patients. Many studies have focused on infections or device complications, but fewer studies have focused on major cardiopulmonary complications, using prospectively collected data. We identified patients who underwent surgery for a primary diagnosis of lumbar stenosis between 1998 and 2009 from the Veterans Affairs National Surgical Quality Improvement Program database. We created a composite of major medical complications, including acute myocardial infarction, stroke, pulmonary embolism, pneumonia, systemic sepsis, coma, and cardiac arrest. Among 12,154 eligible patients, major medical complications occurred in 2.1%, wound complications in 3.2%, and 90-day mortality in 0.6%. Major medical complications, but not wound complications, were strongly associated with age. American Society of Anesthesiologists (ASA) class was a strong predictor of complications. Insulin use, long-term corticosteroid use, and preoperative functional status were also significant predictors. Fusion procedures were associated with higher complication rates than with decompression alone. In logistic regressions, ASA class and age were the strongest predictors of major medical complications (odds ratio for ASA class 4 vs. class 1 or 2: 2.97; 95% confidence interval, 1.68-5.25; P = 0.0002). After adjustment for comorbidity, age, and functional status, fusion procedures remained associated with higher medical complication rates than were decompressions alone (odds ratio = 2.85; 95% confidence interval, 2.14-3.78; P < 0.0001). ASA class, age, type of surgery, insulin or corticosteroid use, and functional status were independent risk factors for major medical complications. These factors may help in selecting patients and planning procedures, improving patient safety.

Applying Criteria of Active Surveillance to Low-Risk Papillary Thyroid Cancer Over a Decade: How Many Surgeries and Complications Can Be Avoided?

2017-04-01

The 2015 American Thyroid Association guidelines acknowledged that "an active surveillance management approach can be considered as an alternative to immediate surgery" in patients with low-risk papillary thyroid carcinoma (PTC). The aim of this study was to determine the proportion of PTC that would meet the criteria for active surveillance and the surgeries and complications that could have been avoided. A total of 681 patients with thyroid cancer who underwent thyroid surgery from 2003 to 2012 were retrospectively reviewed. A decision-making framework for active surveillance was applied to patients with PTC in nodules measuring ≤1.5 cm on ultrasound. Patients were identified as suitable for active surveillance based on imaging and patient characteristics. These patients were reviewed for management and outcomes. PTC was diagnosed based on fine-needle aspiration histology of Bethesda V or VI in thyroid nodules in 243 patients. Of these, 77 patients had nodules measuring ≤1.5 cm on ultrasound, and 56/77 (23%) patients met the criteria for surveillance: 15/243 (6%) patients met the criteria with a ≤1 cm size threshold, and 41/243 (17%) met the criteria with a 1.1-1.5 cm threshold. Of the 56 patients who met the criteria for active surveillance, 52 underwent total thyroidectomy, and four had a lobectomy. Forty-five (80%) patients had elective central nodal dissection, and 14 had nodal metastases on pathology (all <4 mm). Three patients had permanent complications from surgery, including vocal cord paralysis, hypoparathyroidism, and a chipped tooth from intubation. No patients died or had recurrent disease. Future programs in the United States should consider increasing the size threshold for active surveillance of PTC to 1.5 cm, since this will allow up to one quarter of patients to be eligible instead of only 6% with a 1 cm size threshold. Without an active surveillance program, the majority of patients with low-risk cancers have thyroidectomy and carry a small risk of permanent complications.

2017-02-01

To evaluate the clinical course after early surgical treatment with excision of retinal hemangioblastomas (RHs) before development of major complications. Interventional case series of four eyes (four patients) with a peripheral RH that had not yet been treated by laser or cryotherapy prior to surgery. All eyes underwent 23-gauge vitrectomy with lesion excision. One patient underwent ligation of the feeder vessel prior to lesion excision. Best-corrected visual acuity and clinical course were assessed during a follow-up period of at least 4 years. Four patients (mean age 27.3 years; range 19-32) were included, of whom two had von Hippel-Lindau syndrome. Visual acuity improved in three patients (mean 4.8 lines; range 3-10) and remained stable at 0.0 logMAR in one patient. There were no intraoperative complications. Postoperative complications included transient mild vitreous haemorrhage (n = 2), and local epiretinal membrane formation at the excision location (n = 1). At 4 years postoperatively, there were no long-term complications. There was one case of a new lesion, which was effectively treated with laser. Vitrectomy with RH excision seems to be an effective approach for larger RHs and could be considered an early treatment option in selected cases. Postoperative complications were limited in scope of this case series. Important points to consider during vitrectomy are effective closure of feeder and draining vessels as well as complete removal of posterior hyaloid and epiretinal membranes in order to avoid postoperative vitreous haemorrhage and proliferative vitreoretinopathy. © 2016 Acta Ophthalmologica Scandinavica Foundation.

2016-09-01

Our goal was to determine the optimal timing for repair of bile duct injuries sustained during cholecystectomy. Bile duct injury during cholecystectomy is a serious complication that often requires surgical repair. There is heterogeneity in the literature regarding the optimal timing of surgical repair, and it remains unclear to what extent timing determines postoperative morbidity and long-term anastomotic function. A single institution prospective database was queried for all E1 to E4 injuries from 1989 to 2014 using a standardized tabular reporting format. Timing was stratified into 3 groups [early (<7 days), intermediate (8 days until 6 weeks), and late (>6 weeks) after injury]. Analysis was stratified between those who had a previous bile duct repair or not, including postoperative complications and anastomotic failure as outcome variables in 2 separate multivariate logistic regression models. There were 614 patients included in the study. The mean age was 41 years (range, 15-85 yrs), and the majority were female (80%). The mean follow-up time was 40.5 months. Side-to-side hepaticojejunostomy was performed in 94% of repairs. Intermediate repair was associated with a higher risk of postoperative complications [odd ratio = 3.7, 95% confidence interval (1.3-10.2), P = 0.01] when compared with early and late in those with a previous repair attempt. Sepsis control and avoidance of biliary stents were protective factors against anastomotic failure. Adequate sepsis control and delayed repair of biliary injuries should be considered for patients presenting between 8 days and 6 weeks after injury to prevent complications, if a previous bile duct repair was attempted.

Parenteral nutrition is a life-saving modality, but one that also carries risks for potentially life-threatening complications. Comprehensive management of patients receiving parenteral nutrition includes careful selection of candidates, individualizing formulas to meet patients' unique needs, monitoring response to therapy, and implementing strategies designed to avoid complications. Measures to mitigate the risk of central line-associated bloodstream infections are particularly important. As with all complex therapies, a collaborative, multidisciplinary approach promotes optimal outcomes.

We describe 2 unusual cases of vaginal dehiscence after intracavitary brachytherapy performed following robotic laparoscopic hysterectomy (RLH) along with their management. This unusual complication, which may be more common because of the robotic procedures, can be prevented by careful examination and possible delay of the onset of brachytherapy, if indicated. Our report reviews techniques of avoiding this complication and suggests that these complications should be discussed with the patients. PMID:23349653

Liver fibrosis is a risk factor for hepatectomy but cannot be determined accurately before hepatectomy because diagnostic procedures are too invasive. Magnetic resonance elastography (MRE) can determine liver stiffness (LS), a surrogate marker for assessing liver fibrosis, non-invasively. The aim of this study was to investigate whether the LS value determined by MRE is predictive of major complications after hepatectomy. This prospective study enrolled consecutive patients who underwent hepatic resection between April 2013 and August 2016. LS values were measured by imaging shear waves by MRE in the liver before hepatectomy. The primary endpoint was major complications, defined as Clavien-Dindo grade IIIa or above. Logistic regression analysis identified independent predictive factors, from which a logistic model to estimate the probability of major complications was constructed. A total of 96 patients were included in the study. Major complications were observed in 15 patients (16 per cent). Multivariable logistic analysis confirmed that higher LS value (P = 0·021) and serum albumin level (P = 0·009) were independent predictive factors for major complications after hepatectomy. Receiver operating characteristic (ROC) analysis showed that the best LS cut-off value was 4·3 kPa for detecting major complications, comparable to liver fibrosis grade F4, with a sensitivity of 80 per cent and specificity of 82 per cent. A logistic model using the LS value and serum albumin level to estimate the probability of major complications was constructed; the area under the ROC curve for predicting major complications was 0·84. The LS value determined by MRE in patients undergoing hepatectomy was an independent predictive factor for major complications. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

Post-ERCP acute pancreatitis and its risk factors.

PubMed

Iorgulescu, A; Sandu, I; Turcu, F; Iordache, N

2013-03-15

Endoscopic retrograde cholangiopancreatography (ERCP) is a complex endoscopic technique that evolved from a diagnostic to a mainly therapeutic procedure. This was due to the identification of post-procedural complications that can follow both simple ERCP and that associated with the instrumentation of the biliary and pancreatic ductals. The identification of post ERCP complications in a proportion of 5 to 10% of cases, with a mortality rate of 0.33%, imposed their analysis and study of risk factors involved in their occurrence. The significance of post ERCP complications reveals the necessity of their avoidance by adopting additional measures if risk factors are identified. We have retrospectively analyzed 900 cases that underwent ERCP in the Surgery Department of "Sf. Ioan" Clinical Hospital in a period of 17 years. The complications of the procedure were studied. Among them, a special attention was given to post-ERCP acute pancreatitis (pERCP-AP), the most common complication that occurred in the study group. We also tried to find out and highlight the risk factors for this complication. ERCP is a relatively safe invasive procedure, yet it has complications (8% of cases), some of them potentially fatal (mortality 0.43%). The most common complications after ERCP are acute pancreatitis (3.7%), papillary bleeding (1.04%), retroperitoneal duodenal perforation (0.69%) and biliary septic complications like acute cholecystitis and cholangitis (1.21%). Acute pancreatitis is by far the most common complication. Risk factors for its occurrence are difficult sphincterotomy with precut use, failure of CBD desobstruction, pancreatic sphincterotomy, repeated injection of contrast in the pancreatic ductal system, dysfunction of the sphincter of Oddi and the absence of changes of chronic pancreatitis. When risk factors are identified, the patients' selection must be very strict and diagnostic ERCP should be avoided in favor of non-invasive diagnostic methods (MRI-cholangiography, echo-endoscopy).

To gain insight into nurses' knowledge and attitudes regarding major immobility complications (pressure ulcers, pneumonia, deep vein thrombosis and urinary tract infections) and explore the correlation of nurses' knowledge and attitudes with the incidence of these complications. Immobility complications have adverse consequences, and effective management requires appropriate knowledge, attitudes and skills. Evidence about nurses' knowledge and attitudes regarding immobility complications is lacking. Cross-sectional study. A total of 3,903 nurses and 21,333 bedridden patients from 25 hospitals in China were surveyed. Nurses' knowledge and attitudes regarding major immobility complications were assessed using researcher-developed questionnaires. The content validity, reliability and internal consistency of the questionnaires were validated through expert review and a pilot study. The incidence of major immobility complications among bedridden patients from selected wards was surveyed by trained investigators. Correlations between knowledge, attitudes and the incidence of major immobility complications were evaluated with multilevel regression models. Mean knowledge scores were 64.07% for pressure ulcers, 72.92% for deep vein thrombosis, 76.54% for pneumonia and 83.30% for urinary tract infections. Mean attitude scores for these complications were 86.25%, 84.31%, 85.00% and 84.53%, respectively. Knowledge and attitude scores were significantly higher among nurses with older age, longer employment duration, higher education level, previous training experience and those working in tertiary hospitals or critical care units. Nurses' knowledge about pressure ulcers was negatively related to the incidence of pressure ulcers, and attitude towards pneumonia was negatively correlated with the incidence of pneumonia. Clinical nurses have relatively positive attitudes but inadequate knowledge regarding major immobility complications. Improved knowledge and attitudes regarding major immobility complications may contribute to reducing these complications. Nursing managers should implement measures to improve nurses' knowledge and attitudes regarding major immobility complications to reduce the incidence of these complications in bedridden patients. © 2018 John Wiley & Sons Ltd.

Postsurgical acute suppurative parotitis is a bacterial gland infection that occurs from a few days up to some weeks after abdominal surgical procedures. In this study, the authors analyze the prevalence of this complication in Hospital das Clínicas/São Paulo University Medical School by prospectively reviewing the charts of patients who underwent surgeries performed by the gastroenterological and general surgery staff from 1980 to 2005. Diagnosis of parotitis or sialoadenitis was analyzed. Sialolithiasis and chronic parotitis previous to hospitalization were exclusion criteria. In a total of 100,679 surgeries, 256 patients were diagnosed with parotitis or sialoadenitis. Nevertheless, only three cases of acute postsurgical suppurative parotitis associated with the surgery were identified giving an incidence of 0.0028%. All patients presented with risk factors such as malnutrition, immunosuppression, prolonged immobilization and dehydration. In the past, acute postsurgical suppurative parotitis was a relatively common complication after major abdominal surgeries. Its incidence decreased as a consequence of the improvement of perioperative antibiotic therapy and postoperative support. In spite of the current low incidence, we believe it is important to identify risks and diagnose as quick as possible, in order to introduce prompt and appropriate therapeutic measures and avoid potentially fatal complications with the evolution of the disease.

Retrospective case-control study. To examine the postoperative complications of posterior spinal fusion in a population of patients with Rett syndrome (RS). Scoliosis is a common feature of RS, a progressive neurologic disorder affecting almost exclusively females. Despite this, there is little published information regarding the surgical treatment of scoliosis in this disorder. Sixteen consecutive female patients with RS treated by posterior spinal fusion and unit rod instrumentation for progressive scoliosis between 1995 and 2003 were evaluated. Only patients with a minimum of 2-year follow-up were included. Preoperative medical conditions and postoperative complications were recorded. As a control group, we randomly selected 32 spastic quadriplegic patients who underwent the identical procedure during the same time period, selected from our database and matched according to age, level of neurologic impairment, and medical complexity. There was a high rate of early medical complications in the RS patients, with 28 major and 37 minor complications. Only 1 patient did not have a major medical complication, and every patient had at least 1 minor gastrointestinal and/or respiratory complication. Major respiratory complications occurred in 10 patients (63%) and comprised 61% of all major complications. Major gastrointestinal complications occurred in 6 patients (37%) and comprised 21% of all major complications. Other major complications included disseminated intravascular coagulopathy (1 patient), subacute bacterial endocarditis (1 patient), sacral decubiti requiring surgical debridement (2 patients), and extensive bilateral heterotopic ossification of the hips (1 patient). There were no cases of instrumentation failure, pseudarthrosis, deep infection, or need for rod revision. Postoperative complication scores were similar to those in patients with spastic quadriplegic pattern cerebral palsy. Spinal fusion for scoliosis in RS can give a satisfactory technical result, but a high rate of early postoperative medical problems should be anticipated.

On Voxel based Iso-Tumor Control Probabilty and Iso-Complication Maps for Selective Boosting and Selective Avoidance Intensity Modulated Radiotherapy

PubMed Central

Kim, Yusung; Tomé, Wolfgang A.

2010-01-01

Summary Voxel based iso-Tumor Control Probability (TCP) maps and iso-Complication maps are proposed as a plan-review tool especially for functional image-guided intensity-modulated radiotherapy (IMRT) strategies such as selective boosting (dose painting) and conformal avoidance IMRT. The maps employ voxel-based phenomenological biological dose-response models for target volumes and normal organs. Two IMRT strategies for prostate cancer, namely conventional uniform IMRT delivering an EUD = 84 Gy (equivalent uniform dose) to the entire PTV and selective boosting delivering an EUD = 82 Gy to the entire PTV, are investigated, to illustrate the advantages of this approach over iso-dose maps. Conventional uniform IMRT did yield a more uniform isodose map to the entire PTV while selective boosting did result in a nonuniform isodose map. However, when employing voxel based iso-TCP maps selective boosting exhibited a more uniform tumor control probability map compared to what could be achieved using conventional uniform IMRT, which showed TCP cold spots in high-risk tumor subvolumes despite delivering a higher EUD to the entire PTV. Voxel based iso-Complication maps are presented for rectum and bladder, and their utilization for selective avoidance IMRT strategies are discussed. We believe as the need for functional image guided treatment planning grows, voxel based iso-TCP and iso-Complication maps will become an important tool to assess the integrity of such treatment plans.

Respiratory foreign body aspiration (FBA) is a common global health problem requiring prompt recognition and early treatment to prevent potentially fatal complications. The majority of FBAs are due to organic objects and treatment is usually via either endoscopic or surgical extraction. FBA of a straight hairpin has been described as a unique entity in the literature, occurring most commonly in females, particularly during adolescence. In the process of inserting hairpins, the pins will typically be between the teeth with the head tilted backwards, while tying their hair with both hands. This position increases the risk of aspiration, particularly if there is any sudden coughing or laughing. To our knowledge, this is the first case report of a 35-mm straight metallic hairpin foreign body that has been successfully retrieved by a radiological snare system under fluoroscopic guidance. This was achieved with the use of a split endotracheal tube, and therefore avoided the need for a thoracotomy in an adolescent female patient.

Postoperative complications frequently follow major abdominal surgery and are associated with increased morbidity and mortality. Early diagnosis and treatment of complications is associated with improved patient outcome. In this study we assessed the value of a step-up diagnosis plan by C-reactive protein and CT-scan (computed tomography-scan) imaging for detection of postoperative complications following major abdominal surgery.An observational cohort study was conducted of 399 consecutivepatients undergoing major abdominal surgery between January 2009 and January 2011. Indication for operation, type of surgery, postoperative morbidity, complications according to the Clavien-Dindo classification and mortality were recorded. Clinical parameters were recorded until 14 days postoperatively or until discharge. Regular C-reactive protein (CPR) measurements in peripheral blood and on indication -enhanced CT-scans were performed.Eighty-three out of 399 (20.6 %) patients developed a major complication in the postoperative course after a median of seven days (IQR 4-9 days). One hundred and thirty two patients received additional examination consisting of enhanced CT-scan imaging, and treatment by surgical reintervention or intensive care observation. CRP levels were significantly higher in patients with postoperative complications. On the second postoperative dayCRP levels were on average 197.4 mg/L in the uncomplicated group, 220.9 mg/L in patients with a minor complication and 280.1 mg/L in patients with major complications (p < 0,001).CT-scan imaging showed a sensitivity of 91.7 % and specificity of 100 % in diagnosis of major complications. Based on clinical deterioration and the increase of CRP, an additional enhanced CT-scan offered clear discrimination between patients with major abdominal complications and uncomplicated patients. Adequate treatment could then be accomplished.

What Financial Incentives Will Be Created by Medicare Bundled Payments for Total Hip Arthroplasty?

Clement, R Carter; Kheir, Michael M; Soo, Adrianne E; Derman, Peter B; Levin, L Scott; Fleisher, Lee A

2016-09-01

Bundled payments are gaining popularity in arthroplasty as a tactic for encouraging providers and hospitals to work together to reduce costs. However, this payment model could potentially motivate providers to avoid unprofitable patients, limiting their access to care. Rigorous risk adjustment can prevent this adverse effect, but most current bundling models use limited, if any, risk-adjustment techniques. This study aims to identify and quantify the financial incentives that are likely to develop with total hip arthroplasty (THA) bundled payments that are not accompanied by comprehensive risk stratification. Financial data were collected for all Medicare-eligible patients (age 65+) undergoing primary unilateral THA at an academic center over a 2-year period (n = 553). Bundles were considered to include operative hospitalizations and unplanned readmissions. Multivariate regression was performed to assess the impact of clinical and demographic factors on the variable cost of THA episodes, including unplanned readmissions. (Variable costs reflect the financial incentives that will emerge under bundled payments). Increased costs were associated with advanced age (P < .001), elevated body mass index (BMI; P = .005), surgery performed for hip fracture (P < .001), higher American Society of Anaesthesiologists (ASA) Physical Classification System grades (P < .001), and MCCs (Medicare modifier for major complications; P < .001). Regression coefficients were $155/y, $107/BMI point, $2775 for fracture cases, $2137/ASA grade, and $4892 for major complications. No association was found between costs and gender or race. If generalizable, our results suggest that Centers for Medicare and Medicaid Services bundled payments encompassing acute inpatient care should be adjusted upward by the aforementioned amounts (regression coefficients above) for advanced age, increasing BMI, cases performed for fractures, elevated ASA grade, and major complications (as defined by Medicare MCC modifiers). Furthermore, these figures likely underestimate costs in many bundling models which incorporate larger proportions of postdischarge care. Failure to adjust for factors affecting costs may create barriers to care for specific patient populations. Copyright © 2016 Elsevier Inc. All rights reserved.

Outcomes after suboccipital decompression without dural opening in children with Chiari malformation Type I

Object Symptomatic pediatric Chiari malformation Type I (CM-I) is most often treated with posterior fossa decompression (PFD), but controversy exists over whether the dura needs to be opened during PFD. While dural opening as a part of PFD has been suggested to result in a higher rate of resolution of CM symptoms, it has also been shown to lead to more frequent complications. In this paper, the authors present the largest reported series of outcomes after PFD without dural opening surgery, as well as identify risk factors for recurrence. Methods The authors performed a retrospective review of 156 consecutive pediatric patients in whom the senior authors performed PFD without dural opening from 2003 to 2013. Patient demographics, clinical symptoms and signs, radiographic findings, intraoperative ultrasound results, and neuromonitoring findings were reviewed. Univariate and multivariate regression analyses were performed to determine risk factors for recurrence of symptoms and the need for reoperation. Results Over 90% of patients had a good clinical outcome, with improvement or resolution of their symptoms at last follow-up (mean 32 months). There were no major complications. The mean length of hospital stay was 2.0 days. In a multivariate regression model, partial C-2 laminectomy was an independent risk factor associated with reoperation (p = 0.037). Motor weakness on presentation was also associated with reoperation but only with trend-level significance (p = 0.075). No patient with < 8 mm of tonsillar herniation required reoperation. Conclusions The vast majority (> 90%) of children with symptomatic CM-I will have improvement or resolution of symptoms after a PFD without dural opening. A non–dural opening approach avoids major complications. While no patient with tonsillar herniation < 8 mm required reoperation, children with tonsillar herniation at or below C-2 have a higher risk for failure when this approach is used. PMID:25932779

A discrete event simulation model of clinical and operating room efficiency outcomes of sugammadex versus neostigmine for neuromuscular block reversal in Canada.

The objective of this analysis is to explore potential impact on operating room (OR) efficiency and incidence of residual neuromuscular blockade (RNMB) with use of sugammadex (Bridion™, Merck & Co., Inc., Kenilworth, NJ USA) versus neostigmine for neuromuscular block reversal in Canada. A discrete event simulation (DES) model was developed to compare ORs using either neostigmine or sugammadex for NMB reversal over one month. Selected inputs included OR procedure and turnover times, hospital policies for paid staff overtime and procedural cancellations due to OR time over-run, and reductions in RNMB and associated complications with sugammadex use. Trials show sugammadex's impact on OR time and RNMB varies by whether full neuromuscular recovery (train-of-four ratio ≥0.9) is verified prior to extubation in the OR. Scenarios were therefore evaluated reflecting varied assumptions for neuromuscular reversal practices. With use of moderate neuromuscular block, when full neuromuscular recovery is verified prior to extubation (93 procedures performed with sugammadex, 91 with neostigmine), use of sugammadex versus neostigmine avoided 2.4 procedural cancellations due to OR time over-run and 33.5 h of paid staff overtime, while saving an average of 62 min per OR day. No difference was observed between comparators for these endpoints in the scenario when full neuromuscular recovery was not verified prior to extubation, however, per procedure risk of RNMB at extubation was reduced from 60% to 4% (reflecting 51 cases prevented), with associated reductions in risks of hypoxemia (12 cases avoided) and upper airway obstruction (23 cases avoided). Sugammadex impact in reversing deep neuromuscular block was evaluated in an exploratory analysis. When it was hypothetically assumed that 30 min of OR time were saved per procedure, the number of paid hours of staff over-time dropped from 84.1 to 32.0, with a 93% reduction in the per patient risk of residual blockade. In clinical practice within Canada, for the majority of patients currently managed with moderate neuromuscular block, the principal impact of substituting sugammadex for neostigmine is likely to be a reduction in the risk of residual blockade and associated complications. For patients maintained at a deep level of block to the end of the procedure, sugammadex is likely to both enhance OR efficiency and reduce residual block complications.

Cervical spine surgery performed for the correct indications yields good results. However, surgeons need to be mindful of the many possible pitfalls. Complications may occur starting from the anaesthestic procedure and patient positioning to dura exposure and instrumentation. This review examines specific complications related to anterior and posterior cervical spine surgery, discusses their causes and considers methods to prevent or treat them. In general, avoiding complications is best achieved with meticulous preoperative analysis of the pathology, good patient selection for a specific procedure and careful execution of the surgery. Cervical spine surgery is usually effective in treating most pathologies and only a reasonable complication rate exists. PMID:27114784

Complications of unsafe abortion: case reports and the need for curriculum review in Nigeria.

Unsafe abortion remains a major reproductive health problem in Nigeria. These are 2 case reports of unsafe abortion, one performed by a patent medicine dealer where a false passage was created in the substance of the cervix to evacuate the uterus using a cannula. A piece of the cannula was left in situ for five years leading to chronic infection and infertility. The second case was performed by a medical practitioner for a second trimester abortion. He deliberately created a false passage in the substance of the cervix to evacuate the uterus leading to severe haemorrhage. We conclude that there is a need to review and improve the training of medical practitioners in termination of pregnancies to avoid unsafe abortion.

2016-11-01

Because of their frequency, ankle sprains are of major clinical and economic importance. The simple sprain with uneventful healing has to be distinguished from the potentially complicated sprain which is at risk of transition to chronic ankle instability. Conservative treatment is indicated for the acute, simple ankle sprain without accompanying injuries and also in cases of chronic instability. If conservative treatment fails, good results can be achieved by anatomic ligament reconstruction of the lateral ankle ligaments. Arthroscopic techniques offer the advantage of joint inspection and addressing intra-articular pathologies in combination with ligament repair. Accompanying pathologies must be adequately addressed during ligament repair to avoid persistent ankle discomfort. If syndesmotic insufficiency and tibiofibular instability are suspected, the objective should be early diagnosis with MRI and surgical repair.

A recent retrospective comparative effectiveness study found that use of the FLOSEAL Hemostatic Matrix in cardiac surgery was associated with significantly lower risks of complications, blood transfusions, surgical revisions, and shorter length of surgery than use of SURGIFLO Hemostatic Matrix. These outcome improvements in cardiac surgery procedures may translate to economic savings for hospitals and payers. The objective of this study was to estimate the cost-consequence of two flowable hemostatic matrices (FLOSEAL or SURGIFLO) in cardiac surgeries for US hospitals. A cost-consequence model was constructed using clinical outcomes from a previously published retrospective comparative effectiveness study of FLOSEAL vs SURGIFLO in adult cardiac surgeries. The model accounted for the reported differences between these products in length of surgery, rates of major and minor complications, surgical revisions, and blood product transfusions. Costs were derived from Healthcare Cost and Utilization Project's National Inpatient Sample (NIS) 2012 database and converted to 2015 US dollars. Savings were modeled for a hospital performing 245 cardiac surgeries annually, as identified as the average for hospitals in the NIS dataset. One-way sensitivity analysis and probabilistic sensitivity analysis were performed to test model robustness. The results suggest that if FLOSEAL is utilized in a hospital that performs 245 mixed cardiac surgery procedures annually, 11 major complications, 31 minor complications, nine surgical revisions, 79 blood product transfusions, and 260.3 h of cumulative operating time could be avoided. These improved outcomes correspond to a net annualized saving of $1,532,896. Cost savings remained consistent between $1.3m and $1.8m and between $911k and $2.4m, even after accounting for the uncertainty around clinical and cost inputs, in a one-way and probabilistic sensitivity analysis, respectively. Outcome differences associated with FLOSEAL vs SURGIFLO that were previously reported in a comparative effectiveness study may result in substantial cost savings for US hospitals.

Transverse rectus abdominus myocutaneous (TRAM) flap is one of the commonly used techniques for breast reconstruction. Postoperative pain relief is of paramount importance following TRAM flap breast reconstruction to avoid potentially preventable complications like chest infection. Several methods of pain control are available, including intrapleural anesthesia. Here we report a case of a patient who developed ventricular standstill as a complication of intrapleural bupivacaine.

Blood bank issues associated with red cell exchanges in sickle cell disease.

PubMed

Sarode, Ravindra; Altuntas, Fevzi

2006-12-01

Sickle cell disease (SCD) patients are prone to develop complications that include stroke, acute chest syndrome, and other crises. Some of these complications require chronic transfusion therapy or red cell exchange (RCE), either for therapeutic or prophylactic reasons. Due to a discrepancy of red cell antigens between African Americans and Caucasians (majority blood donors), the incidence of alloantibody formation is very high, which makes it difficult to find compatible red cell units, especially for urgent RCE. Some of the above conditions require immediate oxygen delivery to the tissues. Thus, SCD patients undergoing RCE should receive red blood cells with special attributes that include matching for Rh and Kell blood group antigens; RBCs should be fresh in order to provide (1) immediate oxygen delivery and (2) longer surviving cells to reduce the interval between RCE. Also, these units should be pre-storage leukoreduced to prevent febrile non-hemolytic reactions and screened for sickle cell traits to avoid transfusing red cells containing HbS. This requires a concerted effort between the apheresis unit, the local blood bank, and the central blood supplier.

Nodule development is a common complication following the use of fillers for soft tissue augmentation and is commonly categorized as inflammatory or non-inflammatory in nature. Inflammatory nodules may appear anywhere from days to years after treatment, whereas non-inflammatory nodules are typically seen immediately following implantation and are usually secondary to improper placement of the filler. Although inflammatory nodules are more common with permanent fillers such as silicone, inflammatory nodule development following administration of temporary fillers such as hyaluronic acid and collagen has also been reported. Treated many times with corticosteroids due to their anti-inflammatory properties, inflammatory nodules may be secondary to infection or biofilm formation, warranting the use of alternative agents. Appropriate and prompt diagnosis is important in avoiding delay of treatment or long-term complications for the patient. This paper addresses the etiology, development, and studied treatment options available for inflammatory nodules secondary to each of the major classes of fillers. With this knowledge, practitioners may expeditiously recognize and manage this common side effect and thus maximize functional and aesthetic benefit.

Diabetes, particularly type 2 diabetes mellitus (T2DM), has reached epidemic proportions in the U.S. and globally, highlighting the need for major improvements in treatment strategies for detecting, preventing, and slowing disease progression. Despite escalating treatment costs, diabetes care remains largely substandard, with hospitalizations for late-stage complications in particular placing a major burden on the healthcare system. Although considerable advances have been made in identifying the risk factors of diabetes and developing treatments, goals targeting prevention have remained elusive. Although there is currently no consensus regarding terminology among public health practitioners, the concept of prevention in terms of diabetes care runs the gamut from interventions used to avoid disease in individuals without risk factors (primordial prevention) to prevention of the consequences of established complications (quaternary prevention). Given the worldwide prevalence of diabetes, it is crucial to improve the quality of care for those diagnosed with overt diabetes, as well as those who have been identified as at risk for developing the disease. Earlier screening enables undiagnosed, asymptomatic individuals with diabetes to be identified sooner, managed more effectively, and where necessary, treated with the appropriate pharmacotherapeutic options in a timely manner. All stakeholders (including government, industry, professional, and patient groups) must partner in concert to address these vital issues so that treatment goals ultimately may be realized.

McTier, Lauren J; Botti, Mari; Duke, Maxine

2014-04-01

The objective of the study was to explore patient participation in the context of pain management during a hospital admission for a cardiac surgical intervention of patients with cardiovascular disease. This is a single-institution study, with a case-study design. The unit of analysis was a cardiothoracic ward of a major metropolitan, tertiary referral hospital in Melbourne, Australia. Multiple methods of data collection were used including preadmission and predischarge patient interviews (n=98), naturalistic observations (n=48), and focus group interviews (n=2). Patients' preference for participation in pain management was not always commensurate with their involvement in pain management. Patients displayed a greater understanding of their role in pain management in terms of reporting pain and the use of multimodal analgesics after surgery. The majority of patients, however, did not understand the importance of reporting pain to avoid complications. Patients had limited opportunity to participate in their pain management. On occasions in which clinicians did involve patients, the involvement appeared to be focused on reporting pain rather than treatment of pain. Patient participation in pain management during hospitalization is not optimal. This has implications for the quality of pain management patients receive. Higher engagement of patients in their pain management during hospitalization is required to ensure comfort, reduce potential for complications, and adequately prepare the patients to manage their pain following discharge from hospital.

Shoulder imbalance, coronal decompensation, and adding-on phenomenon following corrective surgery in patients with adolescent idiopathic scoliosis are known to be related to the fusion level selected. Although many studies have assessed the appropriate selection of the proximal and distal fusion level, no definite conclusions have been drawn thus far. We aimed to assess the problems with fusion level selection for corrective surgery in patients with adolescent idiopathic scoliosis, and to enhance understanding about these problems. This study is a narrative review. We conducted a literature search of fusion level selection in corrective surgery for adolescent idiopathic scoliosis. Accordingly, we selected and reviewed five debatable topics related to fusion level selection: (1) selective thoracic fusion; (2) selective thoracolumbar-lumbar (TL-L) fusion; (3) adding-on phenomenon; (4) distal fusion level selection for major TL-L curves; and (5) proximal fusion level selection and shoulder imbalance. Selective fusion can be chosen in specific curve types, although there is a risk of coronal decompensation or adding-on phenomenon. Generally, wider indications for selective fusions are usually associated with more frequent complications. Despite the determination of several indications for selective fusion to avoid such complications, no clear guidelines have been established. Although authors have suggested various criteria to prevent the adding-on phenomenon, no consensus has been reached on the appropriate selection of lower instrumented vertebra. The fusion level selection for major TL-L curves primarily focuses on whether distal fusion can terminate at L3, a topic that remains unclear. Furthermore, because of the presence of several related factors and complications, proximal level selection and shoulder imbalance has been constantly debated and remains controversial from its etiology to its prevention. Although several difficult problems in the diagnosis and treatment of adolescent idiopathic scoliosis have been resolved by understanding its mechanism and via technical advancement, no definite guideline for fusion level selection has been established. A review of five major controversial issues about fusion level selection could provide better understanding of adolescent idiopathic scoliosis. We believe that a thorough validation study of the abovementioned controversial issues can help address them. Copyright © 2017 Elsevier Inc. All rights reserved.

This study evaluated the short-term cost-effectiveness of the Patient Empowerment Programme (PEP) for diabetes mellitus (DM) in Hong Kong. Propensity score matching was used to select a matched group of PEP and non-PEP subjects. A societal perspective was adopted to estimate the cost of PEP. Outcome measures were the cumulative incidence of all-cause mortality and diabetic complication over a 5-year follow-up period and the number needed to treat (NNT) to avoid 1 event. The incremental cost-effectiveness ratio (ICER) of cost per event avoided was calculated using the PEP cost per subject multiplied by the NNT. The PEP cost per subject from the societal perspective was US$247. There was a significantly lower cumulative incidence of all-cause mortality (2.9% vs 4.6%, P < .001), any DM complication (9.5% vs 10.8%, P = .001) and CVD events (6.8% vs 7.6%, P = .018), in the PEP group. The costs per death from any cause, DM complication or case of CVD avoided were US$14 465, US$19 617 and US$30 796, respectively. The extra amount allocated to managing PEP was small and it appears cost-effective in the short-term as an addition to RAMP. © 2017 John Wiley & Sons Ltd.

The main benefits of robot-assisted transaxillary thyroid surgery are to overcome the technical limitations of other endoscopic procedures for this surgical pathology and to avoid any cervical skin incision. This article describes the first experience of a Romanian team with the endoscopic robot-assisted thyroid surgery. We used the da Vinci SI intuitive surgical system to carry out 50 thyroid operations: 33 unilateral total lobectomies with isthmectomy (TL), 8 unilateral total lobectomies, with contralateral subtotal lobectomy, and 9 total thyroidectomies. Preoperatively, the patients were diagnosed with nodular goiter in 42 cases, nodular autoimmune thyroiditis in 3 cases, Basedow disease in 2 cases, toxic thyroid adenoma in 2 cases, and diffuse goiter in 1 case. We analyzed the clinical characteristics, size and location of the nodules, surgery duration, postoperative complications, pain medication, histopathological findings and postoperative cosmetic results. All surgical procedures were carried out without major incidents. One case required conversion to open approach. The mean length of surgery was 159 ± 38.2 min and the average console time was 68 ± 39.9 min; postoperatively, we recorded one case of transient brachial plexus neurapraxia, one transient vocal cord paresis, one transient hypocalcemia, and four postoperative wound complications. The final histopathological examination revealed two cases of well-differentiated carcinoma. This paper reports the largest series to date in Southeast Europe about robot-assisted transaxillary thyroidectomy. On a group of selected Caucasian patients, postoperative results were similar to open cervicotomy in terms of postoperative complications. The major cosmetic advantage is the absence of scar in the anterior cervical region.

Parenteral and oral antibiotic duration for treatment of pediatric osteomyelitis: a systematic review protocol

PubMed Central

2013-01-01

Background Pediatric osteomyelitis is a bacterial infection of bones requiring prolonged antibiotic treatment using parenteral followed by enteral agents. Major complications of pediatric osteomyelitis include transition to chronic osteomyelitis, formation of subperiosteal abscesses, extension of infection into the joint, and permanent bony deformity or limb shortening. Historically, osteomyelitis has been treated with long durations of antibiotics to avoid these complications. However, with improvements in management and antibiotic treatment, standard of care is moving towards short durations of intravenous antibiotics prior to enteral antibiotics. Methods/Design The authors will perform a systematic review based on PRISMA guidelines in order to evaluate the literature, looking for evidence to support the optimal duration of parenteral and enteral therapy. The main goals are to see if literature supports shorter durations of either parenteral antibiotics and/or enteral antibiotics. Multiple databases will be investigated using a thorough search strategy. Databases include Medline, Cochrane, EMBASE, SCOPUS, Dissertation Abstracts, CINAHL, Web of Science, African Index Medicus and LILACS. Search stream will include medical subject heading for pediatric patients with osteomyelitis and antibiotic therapy. We will search for published or unpublished randomized and quasi-randomized controlled trials. Two authors will independently select articles, extract data and assess risk of bias by standard Cochrane methodologies. We will analyze comparisons between dichotomous outcomes using risk ratios and continuous outcomes using mean differences. 95% confidence intervals will be computed. Discussion One of the major dilemmas of management of this disease is the duration of parenteral therapy. Long parenteral therapy has increased risk of serious complications and the necessity for long therapy has been called into question. Our study aims to review the currently available evidence from randomized trials regarding duration of both parenteral and oral therapy for pediatric acute osteomyelitis.

2018-05-26

This article summarizes available literature regarding the utilization of probiotic and synbiotics in liver transplant (LTX) recipients, reviewing efficacy in both decreasing infectious complications and immunomodulation, as well as exploring safety concerns. Data suggest that the use of probiotics containing Lactobacillus species, either alone or in combination with prebiotics (referred to as synbiotics), may be effective in reducing infectious complications after LTX, a major contributor to graft loss, hospital length of stay, and mortality. Literature evaluating the use of probiotics to induce tolerance, reduce rejection, and prevent damage associated with ischemic reperfusion injury is limited to animal models, but compelling, as it suggests the use of probiotics may augment deleterious immune-mediated processes in this population. While the benefits of probiotics should be weighed against potential risks, these concerns are largely theoretically in the LTX recipient, with the majority of evidence extrapolated from case reports in other immunosuppressed populations. Based on available literature, it may be prudent to avoid products containing Saccharomyces sp, as these were not used in the efficacy studies, and the majority of the adverse event reporting stems from the use of products containing this organism. Further evaluation of the safety and efficacy of probiotic therapy is warranted. Studies specifically designed to elucidate the optimal product and initiation scenario and delineate safety in this population are needed to allow expanded use of this inexpensive, relatively non-toxic, and potentially beneficial therapeutic option after LTX.

The authors evaluated the trait/state issues of harm avoidance in depressive-spectrum disorders and its predictive potential for antidepressant response. Subjects with Diagnostic and Statistical Manual of Mental Disorders (4th edn; DSM-IV) major depressive disorder (n = 39), dysthymic disorder (n = 37), depressive personality disorder (n = 39), and healthy control subjects (n = 40) were evaluated with the Temperament and Character Inventory and the 17-item Hamilton Depression Rating Scale (HDRS-17) at baseline and after a 12 week antidepressant treatment period. Higher harm avoidance scores predicted lesser improvement in subjects with dysthymic disorder and major depressive disorder, as determined by lesser decrease in HDRS-17 scores. Mean harm avoidance scores in depressed subjects were consistently greater than those in healthy controls, controlling for age, gender and diagnosis. Mean harm avoidance scores decreased significantly in all depressive-spectrum disorders after treatment, but still remained higher than harm avoidance scores in control subjects. The present study reports that harm avoidance is a reliable predictor of antidepressant treatment in subjects with major depressive disorder and dysthymic disorder and that harm avoidance is both trait- and state-dependent in depressive-spectrum disorders.

Sublingual pyramidal lobe. Complications of subtotal thyroidectomy for Graves' disease

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sternberg, J.L.

1986-11-01

A potential complication of subtotal thyroidectomy where a large pyramidal lobe is present is described. The pyramidal lobe normally is immobilized inferiorly by its attachment to the thyroidal isthmus. When the isthmus is removed and the pyramidal lobe is left in situ during subtotal thyroidectomy its superior attachments will allow the pyramidal lobe to become situated sublingually. This may produce gagging and nausea. To avoid the complication, it is recommended that the pyramidal lobe be removed during subtotal thyroidectomy. If the patient also is thyrotoxic, I-131 can be used to treat this complication successfully.

Purpose To identify the factors affecting 30-day postoperative complications and 1-year mortality after surgery for colorectal cancer in octogenarians and nonagenarians. Methods Between 2005 and 2014, a total of 204 consecutive patients aged ≥80 years who underwent major colorectal surgery were included. Results One hundred patients were male (49%) and 52 patients had American Society of Anesthesiologists (ASA) score ≥3 (25%). Combined surgery was performed in 32 patients (16%). Postoperative complications within 30 days after surgery occurred in 54 patients (26%) and 30-day mortality occurred in five patients (2%). Independent risk factors affecting 30-day postoperative complications were older age (≥90 years, hazard ratio [HR] with 95% confidence interval [CI] =4.95 [1.69−14.47], P=0.004), an ASA score ≥3 (HR with 95% CI =4.19 [1.8−9.74], P=0.001), performance of combined surgery (HR with 95% CI =3.1 [1.13−8.46], P=0.028), lower hemoglobin level (<10 g/dL, HR with 95% CI =7.56 [3.07−18.63], P<0.001), and lower albumin level (<3.4 g/dL, HR with 95% CI =3.72 [1.43−9.69], P=0.007). An ASA score ≥3 (HR with 95% CI =2.72 [1.15−6.46], P=0.023), tumor-node-metastasis (TNM) stage IV (HR with 95% CI =3.47 [1.44−8.39], P=0.006), and occurrence of postoperative complications (HR with 95% CI =4.42 [1.39−14.09], P=0.012) were significant prognostic factors for 1-year mortality. Conclusion Patient-related factors (older age, higher ASA score, presence of anemia, and lower serum albumin) and procedure-related factors (performance of combined surgical procedure) increased postoperative complications. Avoidance of 30-day postoperative complications may decrease 1-year mortality. PMID:27279741

Colostomy closure: how to avoid complications

Purpose Colostomy is an operation frequently performed in pediatric surgery. Despite its benefits, it can produce significant morbidity. In a previous publication we presented our experience with the errors and complications that occurred during cases of colostomy creation. We now have focused in the morbidity related to the colostomy closure. The technical details that might have contributed to the minimal morbidity we experienced are described. Methods The medical records of 649 patients who underwent colostomy closure over a 28-year period were retrospectively reviewed looking for complications following these procedures. Our perioperative protocol for colostomy closure consisted in: clear fluids by mouth and repeated proximal stoma irrigations 24 h prior to the operation. Administration of IV antibiotics during anesthesia induction and continued for 48 h. Meticulous surgical technique that included: packing of the proximal stoma, plastic drape to immobilize the surgical field, careful hemostasis, emphasis in avoiding contamination, cleaning the edge of the stomas to allow a good 2-layer, end-to-end anastomosis with separated long-term absorbable sutures, generous irrigation of the peritoneal cavity and subsequent layers with saline solution, closure by layers to avoid dead space, and avoidance of hematomas. No drains and no nasogastric tubes were used. Oral fluids were started the day after surgery and patients were discharged 48–72 h after the operation. Results The original diagnoses of the patients were: anorectal malformation (583), Hirschsprung’s disease (53), and others (13). 10 patients (1.5%) had complications: 6 had intestinal obstruction (5 due to small bowel adhesions, 1 had temporary delay of the function of the anastomosis due to a severe size discrepancy between proximal and distal stoma with a distal microcolon) and 4 incisional hernias. There were no anastomotic dehiscences or wound infection. There was no bleeding, no anastomotic stricture and no mortality. Conclusion Based on this experience we believe that colostomy closure can be performed with minimal morbidity provided a meticulous technique is observed. PMID:20714731

This study evaluates baseline patient characteristics and surgical parameters for risk factors of medical complications in ASD patients received posterior long level internal fixation. Analysis of consecutive patients who underwent posterior long-level instruction fixation for adult degenerative scoliosis (ADS) with a minimum of two year follow-up was performed. Pre-operative risk factors, intraoperative variables, peri-operative radiographic parameters, and surgical-related risk factors were collected to analyze the effect of risk factors on medical complications. Patients were separated into groups with and without medical complication. Then, complication group was further classified as major or minor medical complications. Potential risk factors were identified by univariate testing. Multivariate logistic regression was used to evaluate independent predictors of medical complications. One hundred and thirty-one ADS patients who underwent posterior long segment pedicle screws fixation were included. Total medical complication incidence was 25.2%, which included infection (12.2%), neurological (11.5%), cardiopulmonary (7.6%), gastrointestinal (6.1%), and renal (1.5%) complications. Overall, 7.6% of patients developed major medical complications, and 17.6% of patients developed minor medical complications. The radiographic parameters of pre-operative and last follow-up had no significant difference between the groups of medical complications and the major or minor medical complications subgroups. However, the incidence of cerebrospinal fluid leak (CFL) in patients who without medical complications was much lower than that with medical complications (18.4 vs. 42.4%, P = 0.005). Independent risk factors for development of medical complications included smoking (OR = 6.45, P = 0.012), heart disease (OR = 10.07, P = 0.012), fusion level (OR = 2.12, P = 0.001), and length of hospital stay (LOS) (OR = 2.11, P = 0.000). Independent risk factors for development of major medical complications were diabetes (OR 6.81, P = 0.047) and heart disease (OR = 5.99, P = 0.049). Except for the last follow-up, Oswestry Disability Index and visual analog scale of the patient experienced medical complications trend higher score; the clinical outcomes have no significant difference between the medical and major complications groups. Heart disease comorbidity is an independent risk factor for both medical and major medical complications. Smoking, fusion level, and LOS are independent risk factors for medical complication. Diabetes is the independent risk factors for major medical complications.

Caring for women undergoing cardiac ablation.

Radiofrequency cardiac ablation (RFCA) has become the treatment of choice for many cardiac arrhythmias that have not responded to medication. Complications of cardiac ablation include bleeding, thrombosis, pericardial tamponade, and stroke. Many complications are procedure specific, and several complications can be avoided with appropriate nursing care. Quality patient outcomes begin with competent nursing care. Therefore it is vital for a patient undergoing a percutaneous cardiac ablation procedure to receive supportive care and pre- and post-interventional patient education. This article discusses the nursing care of women undergoing RFCA.

Uterine torsion is a rare obstetrical complication whose diagnosis remains challenging. We report a case of 180 degrees dextrogyre torsion at 36(+5) weeks of gestation complicated by partial abruption and in utero fetal death. Emergency cesarean section was performed through an unintentional posterior hysterotomy. Literature reports a few similar cases. Vertical hysterotomy should be advised in this context avoiding incision on lateral sides associated with increased risk of vascular or ureteral injury. Copyright © 2013 Elsevier Masson SAS.

Postoperative infectious complications increase disease recurrence in colorectal cancer patients. We herein investigated the impact of infectious complications on gastric cancer recurrence after curative surgery. In total, 502 patients who underwent R0 resection for gastric cancer were reviewed. Patients were classified into those with infectious complications (IC group) and those without infectious complications (NO group). The risk factors for recurrence-free survival (RFS) were identified. Infectious complications, which occurred in 52 patients (10.4%), included pneumonia, ileus with a systemic inflammatory reaction, anastomotic leakage, and intraperitoneal abscess. The overall 5-year RFS rate was 83% in the NO group and 58% in the IC group (p = 0.000). Multivariate analysis demonstrated that age, ASA score, stage, and infectious complications were significant predictors of RFS. Infectious complications were a risk factor for gastric cancer recurrence. To avoid causing infectious complications, the surgical procedure, surgical strategy, and perioperative care should be carefully planned.

Cost effectiveness of enoxaparin as prophylaxis against venous thromboembolic complications in acutely ill medical inpatients: modelling study from the hospital perspective in Germany.

To estimate, from the hospital perspective in Germany, the cost effectiveness of the low-molecular-weight heparin (LMWH) subcutaneous enoxaparin sodium 40 mg once daily (ENOX) relative to no pharmacological prophylaxis (NPP) and relative to subcutaneous unfractionated heparin (UFH) 5,000 IU three times daily (low-dose UFH [LDUFH]). Each is used in addition to elastic bandages/compression stockings and physiotherapy in the prevention of venous thromboembolic events (VTE) in immobilised acutely ill medical inpatients without impaired renal function or extremes of body weight. The incremental cost-effectiveness ratios (ICERs) of the 'additional cost for ENOX per clinical VTE avoided versus NPP' and 'additional cost for ENOX per episode of major bleeding avoided versus LDUFH' were chosen as target variables. The target variables were quantified using a modelling approach based on the decision-tree technique. Resource use during thromboprophylaxis, diagnosis and treatment of VTEs, episode of major bleeding and secondary pneumonia after pulmonary embolism (PE) was collected from a hospital survey. Costs were exclusively those to hospitals incurred by staff expenses, drugs, devices, disposables, laboratory tests and equipment for diagnostic procedures. These costs were determined by multiplying utilised resource items by the price or tariff of each item as of the first quarter of 2003. Safety and efficacy values of the comparators were taken from the MEDENOX (prophylaxis in MEDical patients with ENOXaparin) and the THE-PRINCE (THromboEmbolism-PRevention IN Cardiac or respiratory disease with Enoxaparin) trials and from a meta-analysis. The evaluation encompassed 8 (6-14) days of thromboprophylaxis plus time to treat VTE and episode of major bleeding in hospital. Point estimates of all model parameters were applied exclusively in the base-case analysis. There were incremental costs of euro 1,106 for ENOX per clinical VTE avoided versus NPP (1 euro approximately equals 1.07 US dollars; average of the first quarter of 2003). ENOX dominated LDUFH: cost savings of euro 55,825 were obtained and 7.7 episodes of major bleeding were avoided by ENOX compared with LDUFH, each per 1000 patients. In comprehensive sensitivity analyses, the robustness of the model and its results was shown. Results of this evaluation suggest that, in immobilised acutely ill medical inpatients, ENOX may offer hospitals in Germany a very cost-effective option for thromboprophylaxis compared with NPP and a cost-saving alternative compared with LDUFH.

Cardiovascular Collapse During Transcatheter Aortic Valve Replacement: Diagnosis and Treatment of the “Perilous Pentad”

PubMed Central

El-Gamel, Adam

2013-01-01

Transcatheter aortic valve replacement (TAVR) has, without a doubt, brought an unprecedented excitement to the field of interventional cardiology. The avoidance of a sternotomy by transfemoral or transapical aortic-valve implantation appears to come at the price of some serious complications, including an increased risk of embolic stroke and paravalvular leakage. The technical challenges of the procedure and the complex nature of the high-risk patient cohort make the learning curve for this procedure a steep one, with the potential for unexpected complications always looming. Although most commonly relating to vascular access, these complications can also result from prosthesis-related trauma or malposition, or from unanticipated trauma from the pacing wire or the super stiff wire. Sudden and unexplained hypotension is often the earliest indicator of major complication and must prompt an immediate and detailed exclusion of five major pathologies: retroperitoneal bleeding from access site rupture, aortic dissection or rupture, pericardial tamponade, coronary ostial obstruction, or acute severe aortic regurgitation. In most cases, these can be dealt with quickly, and by percutaneous means, although open surgery may occasionally be necessary. Increased operator and team experience should make prevention and recognition of these catastrophic complications more complete. For this reason, the importance of specific training, such as that provided by the valve manufacturers through workshops and proctorship, cannot be overemphasized. It is essential that all operators, and indeed all members of the implant team, exert extreme vigilance to the development of intraprocedural complications, which could have rapid and potentially lethal consequences. Greater experience with an improved understanding of these risks, along with the development of better devices, deliverable through smaller and less traumatic sheath technology, will undoubtedly improve the safety and, potentially, widen the applicability of TAVR in the future. Forthcoming innovations include a newer generation of the valves with operator-controlled steerability to facilitate negotiation of tortuous aortic anatomy, as well as fully retrievable and resheathable devices to accommodate the events of dislocation or embolization. The fact that Transcatheter aortic valve implantation (TAVI) is new implies learning from experience but also from mistakes. The TAVI team must be vigilant to recognize and diagnose intraprocedure severe hypotension. The “perilous pentad” of catastrophic causes must be constantly borne in mind: retroperitoneal bleeding from access site rupture, aortic dissection or rupture, pericardial tamponade, coronary ostial obstruction, and acute severe aortic insufficiency.

Predictors of outcome after reconstructive hepatico-jejunostomy for post cholecystectomy bile duct injuries.

Gomes, Rachel M; Doctor, Nilesh H

2015-01-01

Reconstructive hepatico-jejunostomy is recommended for major bile duct injuries (BDIs) during cholecystectomy. Complications of biliary leak, cholangitis, bleeding, anastomotic strictures and biliary cirrhosis remain a major concern affecting a patient's outcome after surgery. The aim of this study was to analyse the results of surgical repair of major BDIs at our institution and identify predictors for the development of major complications. A retrospective study of 57 patients with major BDI after cholecystectomy referred to a tertiary hepato-biliary centre from July 1999 to July 2011 and subsequently managed with reconstructive bilio-enteric anastomosis was performed. Of 57 patents 35 (61.4%) were primary referred. 22 (38.6 %) were secondary referred, of which 17 were for correct reconstructive surgery performed elsewhere and 5 were following attempted endoscopic management. 17 (29.8%) had local and systemic perioperative complications. 13 (22.8%) had major complications (bile leak, bleed, stricture and/or biliary cirrhosis). No association was found between age, type of cholecystectomy, type of injury, vascular injury and occurrence of major complications. Secondarily referred patients after therapeutic interventions (p = 0.010) and reconstructive surgery after repair performed by non-specialists suffered an increased incidence of major complications (p = 0.032). Secondary referral was also an independent predictor of major complications (p = 0.024). Early referral of patients with no previous intervention to a tertiary hepato-biliary center and specialist surgical repair is recommended for improved outcome after reconstructive hepatico-jejunostomy for major BDIs during cholecystectomy.

Penile curvature is a common urological disease. Tunical plication for correction of penile curvature has been much popularized being simpler, adjustable to avoid overcorrection, less bleeding, and less postoperative erectile dysfunction. This study aims to assess the results of modified 16-dot plication technique for correction of congenital and acquired penile curvature and avoidance of knot-associated complications. Eighteen patients underwent correction of their penile curvature using the modified 16-dot plication technique between January 2014 and October 2015. Patients' pre and postoperative data were analyzed. The mean age of patients is 44 years old. Of the patients 15 who were available for follow-up, 8 patients had congenital penile curvature (CPC) and 7 had Peyronie's disease (PD). The angle of deviation ranged from 30° to 90°. Erectile function (EF) was assessed preoperative by IIEF score and duplex ultrasound. Postoperative follow-up at 3 and 6 months revealed straight erect penis in all patients. Longer follow-up at 1 to 2 years, 2 patients complained from slight recurrence of curve (<20°) and 2 patients complained of worsening of their erectile function. Penile shortening was noted by 6 patients. None of our patients stated any knot complication or bothersome, nor do hematomas, numbness, or painful erections. The modified 16-dot plication technique for correction if penile curvature is a safe and effective method. This modification allowed the knots to be tucked in the plicate tunical tissue avoiding knot-associated complications. More investigation on a large scale of patients or multicenter studies is recommended.

A dearth of laboratory tests to study actual human approach-avoidance behavior has complicated translational research on anxiety. The elevated plus-maze (EPM) is the gold standard to assess approach-avoidance behavior in rodents. Here, we translated the EPM to humans using mixed reality through a combination of virtual and real-world elements. In two validation studies, we observed participants' anxiety on a behavioral, physiological, and subjective level. Participants reported higher anxiety on open arms, avoided open arms, and showed an activation of endogenous stress systems. Participants' with high anxiety exhibited higher avoidance. Moreover, open arm avoidance was moderately predicted by participants' acrophobia and sensation seeking, with opposing influences. In a randomized, double blind, placebo controlled experiment, GABAergic stimulation decreased avoidance of open arms while alpha-2-adrenergic antagonism increased avoidance. These findings demonstrate cross-species validity of open arm avoidance as a translational measure of anxiety. We thus introduce the first ecologically valid assay to track actual human approach-avoidance behavior under laboratory conditions.

Neurologic complications after coronary artery bypass grafting remain a concern. Off-pump coronary artery bypass grafting is a surgical strategy proposed to decrease this risk. Use of an off-pump anaortic technique, which leaves the ascending aorta untouched, may result in further reductions. This systematic review of all published evidence compares neurologic complications after anaortic off-pump coronary artery bypass grafting versus that with aortic manipulation. PubMed and Embase were searched up to August 2008. Experts were contacted, and reference lists of retrieved articles were hand searched. The search process was not limited to English-language sources. Observational studies comparing standard off-pump coronary artery bypass grafting technique with anaortic technique were eligible for inclusion if they reported neurologic complications (stroke and transient ischemic attack). Meta-analysis was conducted to assess differences between groups with regard to neurologic complications. Electronic search identified 1428 abstracts, which resulted in retrieval and detailed review of 331 full-text articles. Eight observational studies reported neurologic complications in 5619 anaortic off-pump coronary artery bypass grafting cases and 5779 cases with aortic manipulation. Postsurgical neurologic complications were significantly lower in anaortic off-pump coronary artery bypass grafting cases (odds ratio, 0.46; 95% confidence interval, 0.29-0.72; I(2) = 0.8%; P = .0008). Avoidance of aortic manipulation during off-pump coronary artery bypass grafting decreases neurologic complications relative to standard technique in which the ascending aorta is manipulated. In patients at high risk for stroke or transient ischemic attack, we recommend avoidance of aortic manipulation during off-pump coronary artery bypass grafting.

Primary Ewing's sarcoma of the skull: radical resection and immediate cranioplasty after chemotherapy. A technical note.

PubMed

Castle, Maria; Rivero, Mónica; Marquez, Javier

2013-02-01

The current standard treatment of Ewing's sarcoma is chemotherapy followed by surgery, making an immediate cranial reconstruction in a one-step surgical procedure possible. We describe the technique used to repair a cranial defect after the resection of a primary Ewing's sarcoma of the skull in a one-step surgical procedure. Bone repair with a custom-made cranioplasty immediately after resection of a primary Ewing's sarcoma of the skull avoids deformities and late complications associated with reconstructive surgery after radiotherapy and not interfere with radiotherapy and neither with follow-up. A one-step surgical procedure after chemotherapy for primary Ewing's sarcoma of the skull could be safer, less aggressive and more radical; avoiding deformities and late complications.

Soft-tissue coverage of the neural elements after myelomeningocele repair.

1996-09-01

We retrospectively reviewed all newborns with a diagnosis of myelomeningocele (MMC) admitted to our hospital between January 1990 and September 1994 to determine methods of soft tissue coverage, complication rates, and results. Sixty-five patients underwent repair of thoracic, lumbar, or sacral MMCs. The average size of defect repaired measured 21.3 cm2 (range, 2-80 cm2). Methods of repair included direct approximation of soft tissues with or without undermining (N = 48), Romberg Limberg flaps (N = 8), gluteus maximus or latissimus dorsi musculocutaneous flaps (N = 5), fascioutaneous flaps (N = 3), and V-gamma advancement (N = 1). A total of 18 complications were recorded (27.7%). There were 5 major complications (7.7%) and 13 minor ones (20.0%). Major complications were defined as midline wound dehiscence overlying the neural elements or wound infection leading to meningitis or ventriculitis. All 5 major and 9 minor complications arose in patients undergoing direct soft-tissue approximation. Additionally, all major complications were recorded in defects > 18 cm2. Based on this series, it appears that MMC defects < 18 cm2 can be closed by direct approximation of soft tissues without significant risk or major wound complication. Larger wounds may be successfully closed in this manner, but the risk of major complication is substantial.

The reported rate of complications of reverse shoulder arthroplasty (RSA) seems to be higher than the complication rate of anatomical total shoulder arthroplasty. The reported overall complication rate of primary RSA is approximately 15%; when RSA is used in the revision setting, the complication rate may approach 40%. The most common complications of RSA include instability, infection, notching, loosening, nerve injury, acromial and scapular spine fractures, intra-operative fractures and component disengagement. Careful attention to implant design and surgical technique, including implantation of components in the correct version and height, selection of the best glenosphere-humeral bearing match, avoidance of impingement, and adequate management of the soft tissues will hopefully translate in a decreasing number of complications in the future.

1997-08-01

A review was done to determine the effectiveness of extracorporeal shock wave lithotripsy (ESWL) in the treatment of impacted pancreatic duct calculi. A total of 19 patients, who were potential candidates for radical pancreatic surgery after unsuccessful endoscopic retrograde cholangiopancreatography, sphincterotomy and attempted stone extraction from the pancreatic ducts, underwent ESWL of the calculi. Followup ranged from 6 months to 6 years. Of the 19 patients 14 avoided a major operation and 6 have remained pain-free for the long term. Two patients died of causes not related to ESWL or endoscopic retrograde cholangiopancreatography. Five patients eventually underwent a Whipple or Puestow procedure for relief of symptoms or persistent obstruction. Complications were minimal. ESWL is a valuable adjunct in patients with impacted pancreatic duct calculi unretrievable by primary endoscopic retrograde cholangiopancreatography.

Complex head and neck reconstruction often mandates free tissue transfer to achieve the most optimal outcomes. Unfortunately, such challenging cases are not without risks of complications, the most dreaded of which is loss of the free flap. Aside from loss of the free flap, there are several other potential complications that can result following head and neck reconstruction. Certain complications are avoided with careful planning, others require significant revisions and in certain cases another free flap. This article presents the experience managing a series of unique complications following free flap head and neck reconstruction. Published by Elsevier Inc.

The root displacement into the maxillary sinus could be a complication of oral surgery in the upper jaw. In these cases, the root removal is needed in order to avoid the occurrence of sinus pathologies. Piezosurgery techniques could assure a safer management of such complications, because of the clear surgical visibility and the selective ability of cut. The aim of this article is to present a case of oral surgery complication (root displacement in the right maxillary sinus), in which piezosurgery technique helped for a correct and safe clinical management, allowing to reduce the soft tissue damage.

Fear of hypoglycaemia in parents of young children with type 1 diabetes: a systematic review.

2010-07-15

Many children with type 1 diabetes have poor glycaemic control. Since the Diabetes Control and Complications Trial (DCCT) showed that tighter control reduces complication rates, there has been more emphasis on intensified insulin therapy. We know that patients and families are afraid of hypoglycaemia. We hypothesised that fear of hypoglycaemia might take precedence over concern about long-term complications, and that behaviour to avoid hypoglycaemia might be at the cost of poorer control, and aimed to evaluate the effectiveness of any interventions designed to prevent that. The objective of this review was to systematically review studies concerning the extent and consequences of fear of hypoglycaemia in parents of children under 12 years of age with type 1 diabetes, and interventions to reduce it. MEDLINE, EMBASE, PsycINFO, The Cochrane Library, Web of Science, meeting abstracts of EASD, ADA and Diabetes UK, Current Controlled Trials, ClinicalTrials.gov, UK CRN, scrutiny of bibliographies of retrieved papers and contact with experts in the field.Inclusions: Relevant studies of any design of parents of children under 12 years of age with Type 1 diabetes were included. The key outcomes were the extent and impact of fear, hypoglycaemia avoidance behaviour in parents due to parental fear of hypoglycaemia in their children, the effect on diabetes control, and the impact of interventions to reduce this fear and hypoglycaemia avoidance behaviour. Eight articles from six studies met the inclusion criteria. All were cross sectional studies and most were of good quality. Parental fear of hypoglycaemia, anxiety and depression were reported to be common. There was a paucity of evidence on behaviour to avoid hypoglycaemia, but there were some suggestions that higher than desirable blood glucose levels might be permitted in order to avoid hypoglycaemia. No studies reporting interventions to reduce parental fear of hypoglycaemia were found. The evidence base was limited. Parents of children with Type 1 diabetes reported considerable parental fear of hypoglycaemia, affecting both parental health and quality of life. There is some suggestion that hypoglycaemia avoidance behaviours by parents might adversely affect glycaemic control. Trials of interventions to reduce parental anxiety and hypoglycaemia avoidance behaviour are needed. We suggest that there should be a trial of structured education for parents of young children with Type 1 diabetes.

Early extraction: a silver bullet to avoid nerve injury in lower third molar removal?

PubMed

Zhang, Q-B; Zhang, Z-Q

2012-10-01

This retrospective study evaluated the effects of early extraction of immature lower third molar on preventing complications, particularly nerve injury following lower third molar removal. Patients were grouped according to age and radiographic results: group A (518 patients, ≤23 years, immature teeth with apical foramen not closed); group B (532 patients, >23 years, mature teeth with closed apical foramen). Group A included 230 males and 288 females (average age 17 years). In group A, 808 lower mandibular third molars were extracted bilaterally in 290 and unilaterally in 228 patients; the incidence of complications was 2.48% (20/808) (all were temporary), the incidence of nerve injury was 0%. Group B included 250 males and 282 females (average age 39 years). In group B, 810 lower third molars were extracted bilaterally in 278 and unilaterally in 254 patients; the incidence of complications was 10% (81/810), the incidence of nerve injury was 1.6% (13/810). All complications were temporary, except two removals of permanent inferior alveolar nerve numbness (>6 months). In this study, early removal of the lower third molar was effective in avoiding some postoperative complications, especially nerve injury. Early extraction of lower third molar in youngsters is recommended following a team consultation. Copyright © 2012 International Association of Oral and Maxillofacial Surgeons.

A new cardiac surgery program was developed in a community hospital setting using the operational excellence (OE) method, which is based on the principles of the Toyota production system. The initial results of the first 409 heart operations, performed over the 28 months between March 1, 2008, and June 30, 2010, are presented. Operational excellence methodology was taught to the cardiac surgery team. Coaching started 2 months before the opening of the program and continued for 24 months. Of the 409 cases presented, 253 were isolated coronary artery bypass graft operations. One operative death occurred. According to the database maintained by The Society of Thoracic Surgeons, the risk-adjusted operative mortality rate was 61% lower than the regional rate. Likewise, the risk-adjusted rate of major complications was 57% lower than The Society of Thoracic Surgeons regional rate. Daily solution to determine cause was attempted on 923 distinct perioperative problems by all team members. Using the cost of complications as described by Speir and coworkers, avoiding predicted complications resulted in a savings of at least $884,900 as compared with the regional average. By the systematic use of a real time, highly formatted problem-solving methodology, processes of care improved daily. Using carefully disciplined teamwork, reliable implementation of evidence-based protocols was realized by empowering the front line to make improvements. Low rates of complications were observed, and a cost savings of $3,497 per each case of isolated coronary artery bypass graft was realized. Copyright © 2011 The Society of Thoracic Surgeons.

2008-01-01

The aim of this research was to study the success and morbidity of supracostal access for percutaneous nephrolithotomy (PCNL), as it is often avoided for fear of complications. Between July 2000 and May 2007, 565 patients underwent PCNL, of whom 110 had a supracostal access. All procedures were performed in a single sitting under general anesthesia. Data were analyzed prospectively for indications, stone clearance rates, and preoperative and postoperative complications. Indications for supracostal access included large pelvic stones in 39 patients, partial or complete staghorn stones in 32, calyceal stones with major stone bulk above the level of 12th rib in 35, and upper ureteric stones in four. Patients' ages ranged between 13 and 71 years (mean 44.2 years). Fifty-six cases were left sided and 54 right sided, whereas 103 (93.6%) were radiopaque stones. All tracts were in the 11th intercostal space, though one had an additional tract in the tenth space. Single-tract access was used in 101 cases (91.8%), but nine (8.2%) required a second tract. Overall stone clearance rate with PCNL monotherapy was 86.4%, and this increased to 97.3% with secondary procedures. Overall complication rate was 11.8% and included hydrothorax/hemothorax in ten, perinephric collection in one, infection/sepsis in two, and excessive bleeding in two. Postoperative hospital stay ranged from 2 to 15 days. The supracostal approach gives high stone clearance rates with acceptable morbidity rates and should be attempted in selected cases. Complications when present may be managed easily with conservative measures.

To report major postoperative complications in 1613 dogs with tibial tuberosity advancement (TTA). Retrospective case series. Dogs (n = 1613) with cranial cruciate ligament deficiency treated with TTA. Medical records of TTAs performed between December 2007-2013 were reviewed for age, sex, weight, contralateral stifle surgery, surgical approach, duration of preoperative lameness, presence of meniscal damage, concurrent patellar luxation and simultaneous bilateral TTA. Major postoperative complications were defined as surgical site infection (SSI) (superficial, deep, or organ/space), implant failure, fracture, patellar luxation, and meniscal tear. Major complications were recorded in 13.4% of cases. Superficial SSI (incisional irritation) was diagnosed in 6.9% cases, requiring only antimicrobial therapy. Other complications included postliminary medial meniscal tear (2% incidence), deep SSI (incisional dehiscence, 1.1%), implant failure (1%), patellar luxation (1.2%), fracture (0.9%), and organ/space SSI (septic arthritis, 0.4%). Dogs with normal menisci were less likely to develop postliminary meniscal tears if the medial meniscus was released at the time of TTA (P < .0001). No association was detected between recorded parameters and complications, although dogs >8 years old approached significance (P = .05) in terms of predisposition to major complications. Major complications after TTA are uncommon, even in dogs with concurrent patellar luxation or bilateral simultaneous procedures. In spite of its morbidity, medial meniscal release may prevent postliminary meniscal tears. © 2017 The American College of Veterinary Surgeons.

External ureteroneocystostomy in renal transplantation.

1985-10-01

The urologic complications of 184 consecutive renal transplants (68 living-related and 116 cadaveric) performed at Walter Reed Army Medical Center are reviewed. An anterior extravesical technique modified from Witzel, Sampson, and Lich was used to reimplant the ureter. Urologic complications occurred in 11 patients (6%): urine leak (4), obstruction (3), stricture (3), and total ureteral necrosis (1). These complications occurred in the first 115 patients; no complications have been documented in the last 69 patients. The several advantages of extravesical ureteroneocystostomy include: less operative time, avoidance of a separate cystotomy, virtually no hematuria, ability to use short ureters, no need for splints or stents, shortened Foley catheter drainage, and no interference with native ureteral function. Complications are few and become uncommon with practice.

Current guidelines recommend that patients with Staphylococcus aureus bloodstream infection (SAB) are treated with long courses of intravenous antimicrobial therapy. This serves to avoid SAB-related complications such as relapses, local extension and distant metastatic foci. However, in certain clinical scenarios, the incidence of SAB-related complications is low. Patients with a low-risk for complications may thus benefit from an early switch to oral medication through earlier discharge and fewer complications of intravenous therapy. The major objective for the SABATO trial is to demonstrate that in patients with low-risk SAB a switch from intravenous to oral antimicrobial therapy (oral switch therapy, OST) is non-inferior to a conventional course of intravenous therapy (intravenous standard therapy, IST). The trial is designed as randomized, parallel-group, observer-blinded, clinical non-inferiority trial. The primary endpoint is the occurrence of a SAB-related complication (relapsing SAB, deep-seated infection, and attributable mortality) within 90 days. Secondary endpoints are the length of hospital stay; 14-day, 30-day, and 90-day mortality; and complications of intravenous therapy. Patients with SAB who have received 5 to 7 full days of adequate intravenous antimicrobial therapy are eligible. Main exclusion criteria are polymicrobial bloodstream infection, signs and symptoms of complicated SAB (deep-seated infection, hematogenous dissemination, septic shock, and prolonged bacteremia), the presence of a non-removable foreign body, and severe comorbidity. Patients will receive either OST or IST with a protocol-approved antimicrobial and are followed up for 90 days. Four hundred thirty patients will be randomized 1:1 in two study arms. Efficacy regarding incidence of SAB-related complications is tested sequentially with a non-inferiority margin of 10 and 5 percentage points. The SABATO trial assesses whether early oral switch therapy is safe and effective for patients with low-risk SAB. Regardless of the result, this pragmatic trial will strongly influence the standard of care in SAB.

Restorative proctocolectomy with ileopouch-anal anastomosis (IPAA) is the treatment of choice for intractable or complicated ulcerative colitis(UC). Elderly patients often present with acute colitis requiring emergent subtotal colectomy(SC). Frail patients are at risk of developing septic complications related to the closed rectosigmoidal stump, often requiring formation of a second stoma to be reversed at the time of completion proctectomy. This carries nuisance to such exhausted patients. We propose a simple and inexpensive trick to avoid the need for creating a mucous fistula. IPAA was performed as a 3-stage procedure in emergency settings. The rectosigmoidal stump was closed and placed subcutaneously; skin was closed over it. After SC, if patients showed signs of stump-related pelvic sepsis, a lavage of the rectal stump with povidone iodine solution and with saline was carried out as a rescue treatment aiming to avoid the need of opening the rectal stump to drain sepsis. Thirty-five patients underwent SC for UC between 1987 and 2012. The skin was closed over the closed stump in the 20. Seven patients out of these 20 experienced early stump-related septic complication. In five cases, we were able to avoid opening of the rectal stump, and a second stoma was unnecessary. After opening the closed stump in the remaining ones, a prompt improving of symptoms was observed. Rectal washout was well tolerated and avoided a second stoma in five out of seven patients, with better quality of life and body perception after IPAA surgery. This is relevant when dealing with geriatric patients, needing to completely recover before undergoing completion proctectomy.

Thighplasty is a common bodycontouring procedure, but also associated with a high complication rate. The purpose of this study was to access the outcome of the medial horizontal thigh lift as it is a common surgical technique regarding thigh deformity correction performed at the authors' department. Surgical keysteps, clinical applications, advantages and disadvantages of the procedure are shown. Postoperative evaluation took place with special focus on individual patient satisfaction. Retrospective analysis of 25 bilateral thigh lifts with single medial horizontal incision line was performed. Evaluated data include patient age, sex, body mass index, combined procedures, additional liposuction, weight loss, former bariatric surgery, comorbidities, smoking status and surgical complications. Follow-up was performed with a standardized protocol and the scar was accessed according to the Vancouver-Scare-Scale. Additionally the patients were asked to complete a questionnaire divided into the sections 'scars', 'postoperative result' and 'sexuality'. Average patient-age was 43 years. Average follow-up was 2 years and 8 months. Average weight loss before surgery was 57 kg. 36% of all patients additionally received a liposuction of the medial thigh. In six cases (24%), we observed complications, which were designated as 'minor complications' in five times (conservative management without problems) and 'major complication' in one time (surgical revision). Postoperative patient-satisfaction was high. Compared to the horizontal and vertical combined thigh lift with the classic T-shaped incision lines we observed fewer complications and a reduction of postoperative morbidity. Additionally patient satisfaction was very high. We estimate that the main reason therefore is the avoidance of the vertical scar and its associated short- and longterm problems. The evaluated data confirm the medial horizontal thighplasty as a good and valuablesurgical option for the management of thigh deformities with moderate skin and tissue excess, localized in the upper part of the thigh.

Maternal alloimmunization to fetal red-blood-cell antigens is a major cause of fetal anemia, which can lead to hydrops and perinatal death if untreated. The cornerstone of management during pregnancy is intrauterine intravascular blood transfusion (IUT). Although this procedure is considered relatively safe, complications continue to occur. The aim of this study was to evaluate rates of procedure-related complications and perinatal loss following IUT, and their change over time, in order to identify factors leading to improved outcome. This was a retrospective analysis of all IUTs for red-cell alloimmunization performed at the national referral center for fetal therapy in The Netherlands, from 1988 to 2015. Differences in complication rates and their associations with alterations in transfusion technique after 2001 were assessed. Between 1988 and 2015, 1678 IUTs were performed in 589 fetuses. For IUTs performed in 2001 and onwards, there was significant improvement in survival (88.6% vs 97.0%, P < 0.001) and a decline in procedure-related complications per fetus (9.8% vs 3.3%, P = 0.001) and per procedure (3.4% vs 1.2%, P = 0.003) compared with those performed before 2001. Procedure-related perinatal loss declined from 4.7% to 1.8% per fetus (P = 0.053). Beneficial changes in transfusion technique were routine use of fetal paralysis, increased use of intrahepatic transfusion and avoidance of arterial puncture. IUT has become an increasingly safe procedure in recent years when performed by experienced hands. The chosen technique should be fine-tuned according to the patient's individual situation. The declining complication rates are most likely related to center volume: this rare procedure is best performed in experienced fetal therapy centers. © 2016 Authors.

This review focuses on the treatment of urinary tract infections (UTI) in children and in particular its recent changes. Areas covered: Acute pyelonephritis, acute cystitis and asymptomatic bacteriuria or asymptomatic infections have to be clearly distinguished. Prompt treatment is required in pyelonephritis and cystitis, but not in asymptomatic bacteriuria or infection, in order to avoid selection of more virulent strains. This concept should be considered even in immunocompromised or bedridden children. In case of pyelonephritis, there should be no delay in beginning the antibiotic treatment in order to decrease the risk of long term complication, such as renal scars. Predisposing conditions for UTI, such as voiding anomalies and urinary tract malformation should be carefully evaluated. Expert opinion: One major concern is the increasing resistance to 3 rd generation cephalosporins. Therefore overconsumption in low-risk settings should be absolutely avoided. The prevalence of infections with E. coli producing extended spectrum ß-lactamase (ESBL) is increasing and pediatricians should be aware about the specific treatment options. Any recommendation about (initial) antibiotic treatment should be regularly updated and adapted to local resistance profiles and to economic factors in different health systems.

Purpose: To determine whether the involvement of plastic surgery and the use of vascularized tissue flaps reduces the frequency of major wound complications after radiation therapy for soft-tissue sarcomas (STS) of the extremities. Methods and Materials: This retrospective study evaluated patients with STS of the extremities who underwent radiation therapy before surgery. Major complications were defined as secondary operations with anesthesia, seroma/hematoma aspirations, readmission for wound complications, or persistent deep packing. Results: Between 1996 and 2010, 73 patients with extremity STS were preoperatively irradiated. Major wound complications occurred in 32% and secondary operations in 16% of patients. Plastic surgery closedmore » 63% of the wounds, and vascularized tissue flaps were used in 22% of closures. When plastic surgery performed closure the frequency of secondary operations trended lower (11% vs 26%; P=.093), but the frequency of major wound complications was not different (28% vs 38%; P=.43). The use of a vascularized tissue flap seemed to have no effect on the frequency of complications. The occurrence of a major wound complication did not affect disease recurrence or survival. For all patients, 3-year local control was 94%, and overall survival was 72%. Conclusions: The rates of wound complications and secondary operations in this study were very similar to previously published results. We were not able to demonstrate a significant relationship between the involvement of plastic surgery and the rate of wound complications, although there was a trend toward reduced secondary operations when plastic surgery was involved in the initial operation. Wound complications were manageable and did not compromise outcomes.« less

OBJECTIVE  The study estimated cost of illness from the provider's perspective for diabetic patients who received treatment during the fiscal year 2008 at Waritchaphum Hospital, a 30-bed public district hospital in Sakhon Nakhon province in northeastern Thailand. METHODS  This retrospective, prevalence-based cost-of-illness study looked at 475 randomly selected diabetic patients, identified by the World Health Organization's International Classification of Diseases, 10th revision, codes E10-E14. Data were collected from the hospital financial records and medical records of each participant and were analysed with a stepwise multiple regression. KEY FINDINGS  The study found that the average public treatment cost per patient per year was US$94.71 at 2008 prices. Drug cost was the highest cost component (25% of total cost), followed by inpatient cost (24%) and outpatient visit cost (17%). A cost forecasting model showed that length of stay, hospitalization, visits to the provincial hospital, duration of disease and presence of diabetic complications (e.g. diabetic foot complications and nephropathy) were the significant predictor variables (adjusted R(2) = 0.689). CONCLUSIONS  According to the fitted model, avoiding nephropathy and foot complications would save US$19 386 and US$39 134 respectively per year. However, these savings are missed savings for the study year and the study hospital only and not projected savings, as that would depend on the number of diabetic patients managed in the year, the ratio of complicated to non-complicated cases and effectiveness of the prevention programmes. Nonetheless, given the high avoidable cost associated with complications of diabetes, healthcare providers in Thailand should focus on initiatives that delay the progression of complications in diabetic patients. © 2011 The Authors.

Objective This study aimed to determine the incidence of major complications following both primary and revision transsphenoidal pituitary surgery. Major complications included endocrinopathic, skull base, orbital, hemorrhagic and thromboembolic complications, respiratory failure, and death. Secondarily, this study aimed to examine factors associated with the occurrence of complications. Study Design Retrospective cohort analysis of California and Florida all-payer databases from 2005-2008. Methods The major complication rate following both primary and revision transsphenoidal pituitary surgery was calculated. Bivariate analyses were performed to investigate the relationship of patient characteristics with complication occurrence, and a multivariate model was constructed to determine risk factors associated with these complications. Results 5,277 primary cases and 192 revision cases met inclusion criteria. There was a non-significant absolute difference of 3.09% (95% CI −11.00 to 16.14) between the rate of complications following primary (n=443; 8.39%) and revision (n=22; 11.46%) surgeries. Multivariate analyses showed that patients with Medicare (OR=1.74; 95% CI 1.17 to 2.61), Medicaid (OR=2.13; 95% CI 1.59 to 2.86), or a malignant neoplasm (OR=3.10; 95% CI 1.62 to 5.93) were more likely to have complications. Conclusions The rate of major complications following transsphenoidal pituitary surgery is lower than earlier retrospective reports. The overall complication rate following revision surgery was not significantly different from primary surgery. Insurance status and a diagnosis of a malignant neoplasm were associated with a higher rate of complications. PMID:25263939

Enucleation is increasingly performed for benign or borderline tumours of the pancreas because it is a parenchyma-sparing and less invasive procedure compared to conventional pancreatectomy, which reduces the risk of exocrine and endocrine insufficiency. This study retrospectively evaluated and compared the pre-, intra-, and post-operative clinical characteristics after open and robotic approaches for pancreatic enucleation. Fifty-six cases of enucleation for benign or borderline tumours of the pancreas treated from March 2010 to July 2015 were identified by a retrospective search. These included 25 patients who underwent an open approach and 31 patients who underwent a robotic approach. The clinical characteristics were extracted and compared. The two groups had a similar location and pathology of the tumour. The robotic group had a significantly shorter operation time and significantly less blood loss than the open group. The rates of clinical pancreatic fistula (PF) formation and major complications were similar. The robotic approach could be applied for a tumour on the right side of the pancreas without increasing the incidence of clinical PF or other major complications. The patients with clinical PF had a significantly shorter distance between the lesion and the main pancreatic duct (MPD). Robotic enucleation appears to be a feasible and safe approach for benign or borderline tumours of the pancreas and was associated with similarly favourable surgical outcomes as the open approach. Identifying and avoiding the MPD is an important step during enucleation.

The evolving management of the appendix mass in the era of laparoscopy and interventional radiology.

PubMed

Forsyth, James; Lasithiotakis, Konstantinos; Peter, Mark

2017-04-01

An appendix mass is the result of a walled-off perforation of the appendix which localises, resulting in a mass and it is encountered in up to 7% of patients presenting with acute appendicitis. However, its management is controversial due to the lack of high level evidence. This review article sets out a rationale diagnostic and therapeutic strategy for the appendix mass based upon up-to-date available evidence. A literature review of the investigation and management of appendix mass/complicated appendicitis was undertaken using PubMed, EMBASE and Google Scholar. No prospective studies were identified. The great majority of recent evidence supports a conservative management approach avoiding urgent appendicectomy because of the high risk of major complications and bowel resection. Appendix abscesses over 5 cm in diameter and persistent abscesses should be drained percutaneously along with antibiotics. Appendix phlegmon should be treated with antibiotics alone. Surgery is reserved for patients who fail conservative treatment. Routine interval appendicectomy is not recommended, but should be considered in the context of persistent faecolith, ongoing right iliac fossa pain, recurrent appendicitis and appendix mass persistent beyond 2 weeks. Clinicians should be particularly wary of patients with appendix mass aged over 40 and those with features suggesting malignancy.

To describe diagnoses and factors associated with hospital transfer in nursing home (NH) residents with advanced dementia. Prospective cohort study. Twenty-two Boston, Massachusetts-area NHs. Three hundred twenty-three NH residents with advanced dementia. Data were collected quarterly for up to 18 months. Data regarding transfers were collected with regard to hospitalization or emergency department (ED) visit, diagnosis, and duration of inpatient admission. Information on the occurrence of any acute medical event (pneumonia, febrile episode, or other acute illness) in the prior 90 days was obtained quarterly. Logistic regression conducted at the level of the acute medical event identified characteristics associated with hospital transfer. The entire cohort experienced 74 hospitalizations and 60 ED visits. Suspected infections were the most common reason for hospitalization (44, 59%), most frequently attributable to a respiratory source (30, 41%). Feeding tube-related complications accounted for 47% of ED visits. In adjusted analysis conducted on acute medical events, younger resident age, event type (pneumonia or other event vs febrile episode), chronic obstructive pulmonary disease, and the lack of a do-not-hospitalize (DNH) order (adjusted odds ratio = 5.22, 95% confidence interval = 2.31-11.79) were associated with hospital transfer. The majority of hospitalizations of NH residents with advanced dementia were due to infections and thus were potentially avoidable, because infections are often treatable in the NH. Feeding tube-related complications accounted for almost half of all ED visits, representing a common but underrecognized burden of this intervention. Advance care planning in the form of a DNH order was the only identified modifiable factor associated with avoiding hospitalization. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

External extension of double-J ureteral stent during pyeloplasty: inexpensive stent and non-cystoscopic removal.

The purpose of the study is to describe our experience with the application of externalized double-J ureteral stent (DJUS) during pyeloplasty for correction of ureteropelvic junction obstruction (UPJO) in order to avoid cystoscopy for stent removal. Pyeloplasty was performed in 523 infants with UPJO using miniature pyeloplasty technique. After removing the obstructed segment, a 3-Fr. DJUS was placed into the ureter. In order to avoid cystoscopy for the removal of the stent, a feeding tube was passed through the skin and renal pelvis via a separate stab incision, connected to the DJUS and secured to the external body surface (skin), and the pyeloplasty was completed. The feeding tube along with the stent was removed after 3-4 weeks, respectively. Postoperative follow-up visits were performed 1, 3, and 6 months after the procedure. The mean operative time was 49 min (range 41-79). Patients were discharged after 17 ± 2 h (mean ± SD). No patient experienced bladder spasm or anticholinergic administration. Forty-four patients (8.4 %) experienced minor complications including non-febrile urinary tract infections and mild hematuria. No major complication including urinoma, leakage, and stent migration or displacement was observed during the follow-up period. Stent removal was tolerated by 99.8 % of patients in an outpatient setting with minimal discomfort without performing cystoscopy. Using external DJUS along with a pyelocutaneous stent extension during pyeloplasty is a safe, feasible, and beneficial technique. This technique resulted in high success rate with minimal cost and no renal injury. The non-cystoscopic stent removal and elimination of urethral catheterization following pyeloplasty are the other advantages of this technique.

Ten-year experience with the muscle split technique, bioabsorbable plates, and postoperative bracing for correction of pectus carinatum: the Innsbruck protocol.

We reviewed further clinical experience with our approach for pectus carinatum repair: modified surgical approach of pectoralis muscle split technique, bioabsorbable plates with screws, and postoperative compressive brace. From April 2000 to February 2010, 55 patients underwent pectus carinatum repair at our department with modifications of conventional Ravitch repair. There were 14 female and 41 male patients, mean age of 19.3 years at the onset of treatment. Postoperative treatment involved fitting of a lightweight, patient-controlled chest brace. Average follow-up was 13.7 months. Patient satisfaction was excellent for 40 patients (72.7%) and good for the remaining 15 (27.3%); aesthetic appearance was excellent for 37 patients (67.3%) and good for the remaining 18 (32.7%). Postoperative evaluation was objective measurement with a thorax caliper and clinical examination. No major perioperative complications were observed. Postoperative complications were mild recurrence of deformity (n = 3) and persistent, mild, single costal cartilage protrusion (n = 2). No patient had palpable plates or screws, and there was no material breakdown. The combination of muscle split technique and absorbable osteosynthesis represents an alternative in pectus carinatum repair. The pectoralis muscle split technique allows early patient mobilization and rehabilitation. Bioabsorbable plates get completely absorbed, avoiding second operation, and chest brace provides postoperative immobilization of the anterior thoracic wall during healing and avoids development of hypertrophic scars. Our combined approach to the correction of pectus carinatum deformities yields predominantly excellent esthetic results, with low morbidity, low costs, and less invasiveness, leading to high patient satisfaction.

Nowadays cataract extraction combined intraocular lens (IOL) implantation has become the conventional treatment for cataract. Numbers of IOL exchange after cataract extraction combined IOL implantation have been increasing in recent years. As a non-routine surgery, IOL exchange is normally combined with other surgeries and accompanied by some complications to various extents. Is IOL exchange necessary for all abnomal IOLs? Can IOL exchange be avoided? How to avoid IOL exchange? The purpose of this article is to stress the importance of indication of IOL exchange and how to avoid IOL exchange.

The older orthopaedic patient: general considerations.

PubMed

Potter, Jane F

2004-08-01

People older than 65 years are more likely to need elective and emergent orthopaedic surgery compared with younger persons. They also experience significant benefits. Although age-related changes increase the risk of perioperative complications, understanding those changes allows prevention or at least early recognition and treatment when problems arise. Because of comorbidities, older persons take more medications that need to be managed in the perioperative period. Care could be simplified if patients were to bring their medications to the preoperative evaluation. Central nervous system sensitivity to certain pain medications (meperidine and propoxyphene) means that these drugs are best avoided as good alternatives exist (morphine and oxycodone). Adverse reactions to drugs are an important cause of acute confusion (delirium) that often complicates orthopaedic care. Early mobilization after surgery, avoiding certain drugs, avoiding restraints (including Foley catheters), attending to hydration, promoting normal sleep, compensating for sensory disorders, and stimulating daytime activities can prevent delirium. Patients with dementia are more likely to have delirium develop and, like many older people, will present special challenges in communication and decision making. Including family members in discussions may be helpful in ensuring truly informed consent.

Predictors of kidney biopsy complication among patients with systemic lupus erythematosus.

Kidney biopsy is essential for the diagnosis and management of lupus nephritis. The risk of bleeding complication, however, is not defined in the systemic lupus erythematosus population. A retrospective cohort study was conducted to determine predictors of major and minor complications among patients with systemic lupus erythematosus undergoing percutaneous ultrasound-guided kidney biopsy. Major complications included bleeding necessitating intervention, hypotension requiring vasopressors or higher level of care or death. Minor complications included moderate or large (≥ 4 cm in largest diameter) perinephric hematoma, gross hematuria or voiding difficulties. All patients were observed for at least 23 h post-procedure. The overall incidence of bleeding was 10.5% (2.7% major, 7.8% minor). Adjusted logistic regression showed that for every 10,000 cells/mm(3) decrease in platelet count, risk for major and any complication increased by 27% (odds ratio 1.27; 95% confidence intervals 1.06-1.51; p = 0.01) and 8% (odds ratio 1.08; 95% confidence intervals 1.02-1.15; p = 0.01), respectively. Patients with a platelet count <150,000 cells/mm(3) were 30 times more likely to experience a major complication (p = 0.002). Other candidate predictors, including steroid exposure, kidney function, hematocrit and histopathology, were not significant. Kidney biopsies are well tolerated in patients with systemic lupus erythematosus. However, patients with pre-biopsy platelet counts <150,000 cells/mm(3) are at markedly increased risk for a major bleeding complication.

Higher concentration local anaesthetics causing prolonged anaesthesia. Do they? A literature review and case reports.

PubMed

Kingon, A; Sambrook, P; Goss, A

2011-12-01

Higher concentration dental local anaesthetics (3% and 4%) have become more available in Australia in recent years. Benefits claimed include a faster onset of anaesthesia and improved success with injections compared to 2% solutions. Recent reports suggest that the higher concentration carries a greater risk of prolonged anaesthesia to the mandibular and particularly the lingual nerves. The literature was reviewed and those studies which demonstrated adverse effects of different concentrations of local anaesthetics were analysed. Recent cases are presented. There is an extensive international literature which confirms increased concentration of local anaesthetic does show an increased risk, by about ×6, of prolonged anaesthesia. Five case reports illustrate the impact of this complication on patients' quality of life. Careful consideration needs to be given before using higher concentration local anaesthetic agents for mandibular and lingual blocks as lower concentration local anaesthetics are safer. If acceptable to individual patients, avoidance of block injections or any local anaesthetic for minor restorative tasks could be encouraged given the severity of the complication. It is safe to use the higher concentration agents for infiltrations away from major nerves. © 2011 Australian Dental Association.

Hip and groin pain in the child athlete.

An increasing number of children are taking up sporting activities and at more competitive levels. For this reason (pediatric) radiologists should expect to receive greater numbers of requests from their orthopedic colleagues to image the athletic child who presents with hip or groin pain: "athletic pubalgia."Lower limb sports-related pathology is particularly common in sports such as ballet, football, hockey, rugby, and running. Injuries to the hip and groin may account for up to a quarter of injuries seen in athletic children and may be acute or chronic, osseous, cartilaginous, ligamentous, or muscular. The radiologist should also bear in mind the possibility of non-sports-related pathology such as inflammation or tumor and of complications related to previous trauma such as avascular necrosis or femoroacetabular impingement complicating previous slipped capital femoral epiphysis. Radiologists should avoid use of the term sports hernia and provide a more specific description of the true abnormality.The major imaging modalities are radiographs and MRI. In this article we provide an overview of the common sports-related pathologies of the hip and groin that may be encountered in the athletic child.

Parenteral Nutrition and Intestinal Failure

PubMed Central

Bielawska, Barbara; Allard, Johane P.

2017-01-01

Severe short bowel syndrome (SBS) is a major cause of chronic (Type 3) intestinal failure (IF) where structural and functional changes contribute to malabsorption and risk of micronutrient deficiencies. Chronic IF may be reversible, depending on anatomy and intestinal adaptation, but most patients require long-term nutritional support, generally in the form of parenteral nutrition (PN). SBS management begins with dietary changes and pharmacologic therapies taking into account individual anatomy and physiology, but these are rarely sufficient to avoid PN. New hormonal therapies targeting intestinal adaptation hold promise. Surgical options for SBS including intestinal transplant are available, but have significant limitations. Home PN (HPN) is therefore the mainstay of treatment for severe SBS. HPN involves chronic administration of macronutrients, micronutrients, fluid, and electrolytes via central venous access in the patient’s home. HPN requires careful clinical and biochemical monitoring. Main complications of HPN are related to venous access (infection, thrombosis) and metabolic complications including intestinal failure associated liver disease (IFALD). Although HPN significantly impacts quality of life, outcomes are generally good and survival is mostly determined by the underlying disease. As chronic intestinal failure is a rare disease, registries are a promising strategy for studying HPN patients to improve outcomes. PMID:28481229

The clinical outcomes of lumbar fusion are diminished by the complications associated with the surgical approach. Posterior approaches cause segmental muscular necrosis and anterior approaches risk visceral and vascular injury. This report details a two-year prospective study of a percutaneous method which avoids the major problems associated with existing approaches. Seventeen patients underwent percutaneous, trans-sacral fusion and fixation of L5-S1 with the assistance of computer guidance. Each patient was followed for a minimum of two years post surgery. SF-36 questionnaires and radiographs were obtained preoperatively and at two years post-operatively. Fusion was assessed with post-operative radiographs and/or CT scan. Ninety-three percent of the people fused as judged by plain AP films, Ferguson's view radiographs, and/or CT scans at the two year follow-up. Prospective health and functional SF-36 scores showed significant improvement from the preoperative to the postoperative period. There were no significant complications related to the approach or to the placement of the implants. Percutaneous fusion of the lumbosacral spine appears safe and provides excellent clinical results with a minimal amount of associated tissue trauma.

One of the earliest but often unaddressed signs of facial aging is volume loss in the temple. Treatment of the area can produce satisfying results for both patient and practitioner. Safe injection requires explicit knowledge of the anatomy to avoid complications related to the multitude of vessels that course throughout the region at various depths. The authors aim to detail the anatomy of the area and provide a safe and easy-to-follow method for injection. The authors review the relevant anatomy of the temporal region and its application to cosmetic filler injections. The authors describe an easy-to-follow approach for a safe and effective injection window based on numerous anatomical studies. Injection in this area is not without risk, including potential blindness. The authors review the potential complications and their treatments. Hollowing of the temple is an early sign of aging that, when corrected, can lead to significant patient and practitioner satisfaction. Proper anatomically knowledge is required to avoid potentially severe complications. In this study, the authors present a reliable technique to safely and effectively augment this often undertreated area of the aging face.

Safe percutaneous suprapubic catheterisation.

Goyal, N K; Goel, A; Sankhwar, S N

2012-11-01

We describe our technique of percutaneous suprapubic catheter insertion with special reference to steps that help to avoid common complications of haematuria and catheter misplacement. The procedure is performed using a stainless steel reusable trocar under local infiltrative anaesthesia, usually at the bedside. After clinical confirmation of a full bladder, the trocar is advanced into the bladder through a skin incision. Once the bladder is entered, the obturator is removed and the assistant inserts a Foley catheter followed by rapid balloon inflation. Slight traction is applied to the catheter for about five minutes. Patients with previous lower abdominal surgery, an inadequately distended bladder or acute pelvic trauma do not undergo suprapubic catheterisation using this method. The procedure was performed in 72 men (mean age: 42.4 years, range: 18-78 years) with urinary retention with a palpable bladder. The average duration of the procedure was less than five minutes. No complications were noted in any of the patients. Trocar suprapubic catheter insertion is a safe and effective bedside procedure for emergency bladder drainage and can be performed by resident surgeons. The common complications associated with the procedure can be avoided with a few careful steps.

The thoracic morbidity and mortality (TM&M) classification system univocally encodes the postoperative adverse events by their management complexity. This study aims to compare the distribution of the severity of complications according to the TM&M system versus the distribution according to the classification proposed by European Society of Thoracic Surgeons (ESTS) Database in a population of patients submitted to video assisted thoracoscopic surgery (VATS) lung resection. A total of 227 consecutive patients submitted to VATS lobectomy for lung cancer were analyzed. Any complication developed postoperatively was graded from I to V according to the TM&M system, reflecting the increasing severity of its management. We verified the distribution of the different grades of complications and analyzed their frequency among those defined as "major cardiopulmonary complications" by the ESTS Database. Following the ESTS definitions, 20 were the major cardiopulmonary complications [atrial fibrillation (AF): 10, 50%; adult respiratory distress syndrome (ARDS): 1, 5%; pulmonary embolism: 2, 10%; mechanical ventilation >24 h: 1, 5%; pneumonia: 3, 15%; myocardial infarct: 1, 5%; atelectasis requiring bronchoscopy: 2, 10%] of which 9 (45%) were reclassified as minor complications (grade II) by the TM&M classification system. According to the TM&M system, 10/34 (29.4%) of all complications were considered minor (grade I or II) while 21/34 (71.4%) as major (IIIa: 8, 23.5%; IIIb: 4, 11.7%; IVa: 8, 23.5%; IVb: 1, 2.9%; V: 3, 8.8%). Other 14 surgical complications occurred and were classified as major complications according to the TM&M system. The distribution of postoperative complications differs between the two classification systems. The TM&M grading system questions the traditional classification of major complications following VATS lung resection and may be used as an additional endpoint for outcome analyses.

Transcatheter aortic valve replacement (TAVR) requires large calibre catheters and is therefore associated with increased vascular complications. The aim of this study was to illustrate the impact of the different definitions of major vascular complications on their incidence and to underscore the importance of uniform reporting. We pooled dedicated databases of consecutive patients undergoing TAVR from two tertiary care facilities and looked for the incidence of major vascular complications using various previously reported definitions. The level of agreement (Kappa statistic) between the respective definitions and the Valve Academic Research Consortium (VARC) consensus definition of vascular complications was assessed. A total of 345 consecutive patients underwent transfemoral TAVR and were included in this analysis. A completely percutaneous access and closure technique was applied in 96% of cases. Arterial sheath size ranged between 18 and 24 Fr, the majority being 18 Fr (60%). Procedural success was reached in 94.5%. Depending on the definition used, major vascular complications occurred in 5.2-15.9% of patients. According to the VARC definitions, the rate of major and minor vascular complications was 9.0% and 9.6%, respectively. Major vascular complications according to VARC criteria demonstrated at least a substantial level of agreement with the SOURCE registry (k 0.80), the UK registry (k 0.82) the Italian registry (k 0.72) and "FRANCE" registry (k 0.70) definitions, compared to a moderate level of agreement with the definitions used in the German registry ( 0.47) and the 18 Fr Safety and Efficacy study (k 0.42). Minor complications according to VARC demonstrated a moderate agreement only with vascular complications using the German registry definition (k 0.54). Non-uniformity in how vascular complications are defined precludes any reliable comparison between previously reported TAVR registries. The VARC consensus document offers standardised endpoint definitions and should be universally adopted to obtain better insights into global TAVR experience.

Silent cerebral lesions with the multielectrode-phased radiofrequency (RF) pulmonary vein ablation catheter (PVAC(®)) have recently been investigated. However, comparative data on safety in relation to irrigated RF ablation are missing. One hundred and fifty consecutive patients (58 ± 12 years, 56 female) underwent first pulmonary vein isolation (PVI) for atrial fibrillation (61% paroxysmal) using PVAC(®) (PVAC). Procedure data as well as in-hospital complications were compared with 300 matched patients who underwent PVI using irrigated RF (iRF). Procedure duration (148 ± 63 vs. 208 ± 70 min; P < 0.001), RF duration (24 ± 10 vs. 49 ± 25 min; P < 0.001), and fluoroscopy time (21 ± 10 vs. 35 ± 13 min; P < 0.001) were significantly shorter using PVAC. Major complication rates [major bleeding, transitoric ischaemic attack (TIA), and pericardial tamponade] were not significantly different between groups (PVAC, n = 3; 2% vs. iRF n = 17; 6%). Overall complication rate, including minor events, was similar in both groups [n = 21 (14%) vs. n = 48 (16%)]. Most of these were bleeding complications due to vascular access [n = 8 (5.3%) vs. n = 22 (7.3%)], which required surgical intervention in five patients [n = 1 (0.7%) vs. n = 4 (1.3%)]. Pericardial effusion [n = 4 (2.7%) vs. n = 19 (6.3%); pericardial tamponade requiring drainage n = 0 vs. n = 6] occurred more frequently using iRF. Two patients in each group developed a TIA (1.3% vs. 0.6%). Of note, four of five thromboembolic events in the PVAC group (two TIAs and three transient ST elevations during ablation) occurred when all 10 electrodes were used for ablation. Pulmonary vein isolation using PVAC as a 'one-shot-system' has a comparable complication rate but a different risk profile. Pericardial effusion and tamponade occurred more frequently using iRF, whereas thromboembolic events were more prevalent using PVAC. Occurrence of clinically relevant thromboembolic events might be reduced by avoidance of electrode 1 and 10 interaction and uninterrupted anticoagulation, whereas contact force sensing for iRF might minimize pericardial effusion.

The inherent catastrophic traps in retrograde CTO PCI.

PubMed

2018-05-01

When we learn to drive, our driving instructor tells us how to check the side mirror and turn your head to check the blind spot before changing lanes. He tells us how to stop at stop signs, how to drive in slippery conditions, the safe stopping distances, and these all make our driving safe. Similarly, when we learn PCI, our mentors teach us to seat the guiding catheter co-axially, to wire the vessel safely, to deliver balloon and stents over the wire, to watch the pressure of the guiding, in order that we perform PCI safely and evade complications. In retrograde CTO PCI, there is no such published teaching. Also many individual mentors have not had the wide experience to see all the possible complications of retrograde CTO PCI and, therefore, may not be able to warn their apprentice. As the number of retrograde procedures increase worldwide, there is a corresponding increase in catastrophic complications, many of which, we as experts, can see are easily avoidable. To breach this gap in knowledge, this article describes 12 commonly met inherent traps in retrograde CTO PCI. They are inherent because by arranging our equipment in the manner to perform retrograde CTO PCI, these complications are either induced directly or happen easily. We hope this work will enhance safety of retrograde CTO PCI and avoid many catastrophic complications for our readers and operators. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Diabetic complications in the lower extremity are associated with significant morbidity and mortality, and impact heavily upon the public health system. Early and accurate recognition of these abnormalities is crucial, enabling the early initiation of treatments and thus avoiding or minimizing deformity, dysfunction and amputation. Following careful clinical assessment, radiological imaging is central to the diagnostic and follow-up process. We aim to provide a comprehensive review of diabetic lower limb complications designed to assist radiologists and to contribute to better outcomes for these patients. PMID:26111070

Photoelectric artefact from optogenetics and imaging on microelectrodes and bioelectronics: New Challenges and Opportunities

2015-01-01

Bioelectronics, electronic technologies that interface with biological systems, are experiencing rapid growth in terms of technology development and applications, especially in neuroscience and neuroprosthetic research. The parallel growth with optogenetics and in vivo multi-photon microscopy has also begun to generate great enthusiasm for simultaneous applications with bioelectronic technologies. However, emerging research showing artefact contaminated data highlight the need for understanding the fundamental physical principles that critically impact experimental results and complicate their interpretation. This review covers four major topics: 1) material dependent properties of the photoelectric effect (conductor, semiconductor, organic, photoelectric work function (band gap)); 2) optic dependent properties of the photoelectric effect (single photon, multiphoton, entangled biphoton, intensity, wavelength, coherence); 3) strategies and limitations for avoiding/minimizing photoelectric effects; and 4) advantages of and applications for light-based bioelectronics (photo-bioelectronics).

Transdermal delivery of heparin: Physical enhancement techniques.

PubMed

Ita, Kevin

2015-12-30

Thromboembolic complications are the most common preventable cause of mortality and morbidity in trauma patients. Thrombosis is also the common cause of ischemic heart disease (acute coronary syndrome), stroke, and venous thromboembolism. Heparin, as a potent anticoagulant, has been used in clinical practice for more than five decades and remains the major medicine for the prevention and treatment of venous thromboembolism. However it binds to the endothelium and has a high affinity for plasma proteins resulting in a short half-life and unpredictable bioavailability. Transdermal drug delivery can address the problems of short half-life and unpredictable bioavailability. Other advantages of transdermal drug delivery include convenience, improved patient compliance, prompt termination of dosing and avoidance of the first-pass effect. This review focuses on different approaches used for transdermal delivery of heparin. Copyright © 2015 Elsevier B.V. All rights reserved.

The purpose of this study was to analyze mandibular fracture site, relationship of the fracture line to the periodontium, vitality of teeth, displacement of the fracture segments and their implications, and determine whether to retain or remove the teeth in the fracture line. Fifty patients with 62 fractures were involved in this study. An electric pulp tester was used to measure the pulpal response. The degree of fracture displacement and the relationship of the fracture line to the periodontium were evaluated using panoramic radiographs. Fractures of the parasymphysis region constituted a majority of 60.87% in the gross displacement category. Four of 50 patients showed no response presurgically and minimal response postoperatively on pulp vitality testing. Patients with teeth in the fracture line showing no response on pulp vitality testing should be advised extraction to avoid further complications. PMID:22132255

We analysed the complications of 215 patients with uterine cervix cancer, treated by radiotherapy (RT) alone. It was done according to the rules of the Franco-Italian glossary, presented at the 7th ESTRO meeting, held in The Hague on September 1988. They were ranked by organ sites and by degrees of gravity. The analysis was done on the total number of complications and they were scored at the highest reached grade of gravity. Seventy one complications were found in 55 patients; they were studied by patient, degree of severity, time of onset, organ system and grade, time of onset and grade, time of onset and organ sites, stage and RT doses and brachytherapy volumes. The importance of the study of complications is stressed, particularly when treatment combines external RT and brachytherapy; some guidelines are given to avoid severe complications.

To analyze the cumulative effect of risk factors associated with early major complications in postoperative spine surgery. Retrospective analysis of 583 surgically-treated patients. Early "major" complications were defined as those that may lead to permanent detrimental effects or require further significant intervention. A balanced risk score was built using multiple logistic regression. Ninety-two early major complications occurred in 76 patients (13%). Age > 60 years and surgery of three or more levels proved to be significant independent risk factors in the multivariate analysis. The balanced scoring system was defined as: 0 points (no risk factor), 2 points (1 factor) or 4 points (2 factors). The incidence of early major complications in each category was 7% (0 points), 15% (2 points) and 29% (4 points) respectively. This balanced scoring system, based on two risk factors, represents an important tool for both surgical indication and for patient counseling before surgery.

Over the past 20 years the management of blunt liver trauma has evolved from a primary operative approach to a nonoperative one, for both low and high grade injuries, only on the basis of hemodynamic stability. However, in spite of a high success rate of non operative management, it is frequently observed, also in our country, an old fashioned way to approach these patients, based on habit more than observation and evidence based medicine. We present a case of successful nonoperative treatment of a grade IV blunt liver trauma (lacero-contusive injury of V, VI and VII segments) in a 34-year-old woman. Nowadays more than 85% of liver injuries are managed without operative intervention, irrespective of the injury grade. Success rate of the conservative approach ranges from 82% to 100% and almost all complications (14% in high grade injuries) can be managed with interventional radiology procedures, still avoiding major surgery. Today, in the absence of other abdominal injuries requiring surgical exploration, hemodynamic instability from ongoing hemorrhage after primary evaluation and resuscitative treatment, is the only indication to an operative management of traumatic liver injuries.

Objectives Distraction osteogenesis (DO) mobilises bone regenerative potential and avoids the complications of other treatments such as bone graft. The major disadvantage of DO is the length of time required for bone consolidation. Mesenchymal stem cells (MSCs) have been used to promote bone formation with some good results. Methods We hereby review the published literature on the use of MSCs in promoting bone consolidation during DO. Results Studies differed in animal type (mice, rabbit, dog, sheep), bone type (femur, tibia, skull), DO protocols and cell transplantation methods. Conclusion The majority of studies reported that the transplantation of MSCs enhanced bone consolidation or formation in DO. Many questions relating to animal model, DO protocol and cell transplantation regime remain to be further investigated. Clinical trials are needed to test and confirm these findings from animal studies. Cite this article: Y. Yang, S. Lin, B. Wang, W. Gu, G. Li.

An avoidable hospitalization (AH) is a condition that could have been prevented through effective treatment in outpatient care. Diabetes is often referred to as an ambulatory care-sensitive condition, and its associated hospitalizations are often referred to as avoidable hospitalizations. There are limited data on avoidable hospitalizations for individuals with diabetes in Taiwan. We used the National Health Interview Survey (NHIS) dataset to obtain diabetes-related avoidable hospitalizations for subjects aged above 12 years. We included data from 20,826 subjects who had completed the interview between 2004 and 2005. Data were collected from a total of 15,574 people, who had agreed to link their health information to the Taiwan National Health Insurance Research Database, including basic demographic variables, inpatient or outpatient medical events, admission date, discharge date, and diagnosis. The 1005 individuals who self-reported having diabetes or had at least 1 hospitalization or 2 physician service claims for diabetes mellitus with an ICD-9 diagnosis of 250 were included in the analysis. We divided those with diagnosis of diabetes into two groups: never hospitalized and hospitalized. The never hospitalized group served as the control group. We further identified hospitalized subjects with long-term complications due to diabetes (PQI-3) that included ICD-CM codes 250.4-250.9. The mean ages of patients with diabetes-related long-term complications in the hospitalized and never hospitalized groups were 65 years and 58 years, respectively (p-value<0.01). More than half (52%) of the patients with diabetes-related long-term complications had a body mass index (BMI) lower than 24. The hospitalized group also had lower educational status compared with that of patients in the never hospitalized group (equal to or lower than elementary school, 63% vs. 50%; junior high school, 23% vs. 14%; equal or higher than senior high school, 14% vs. 36%). Furthermore, hospitalized patients tended to have lower household monthly income, were unmarried, and did not have private medical insurance. There were no significance differences in ethnic composition between the groups. Interestingly, patients with frequent retinal examination, and those with lower body mass index had higher frequency of avoidable hospitalization (p<0.01). We found that the following factors were associated with a higher frequency of avoidable hospitalization among patients with type 2 diabetes: elderly, male, lower body mass index, lower household income, non-exercise, higher disease comorbidity, and frequent retinal examination.

To avoid distal plaques embolization during carotid artery stenting, we developed Universal Protection Method that combined the use of a proximal common carotid artery balloon, an external carotid artery balloon, and a distal internal carotid artery filter, with continuous flow reversal to the femoral vein. Herein, we assessed the efficacy of the Universal Protection Method by comparing stenting outcomes before and after its introduction. We assessed outcomes for 115 cases before and 41 cases after the Universal Protection Method was adopted (non-Universal Protection Method and Universal Protection Method groups, respectively). We then compared procedure details, magnetic resonance imaging (within 48 hours after the procedure), intraprocedural complications, and postoperative stroke rates. Ischemic stroke was not observed in the Universal Protection Method group, but 1 major stroke and 2 minor strokes were observed in the non-Universal Protection Method group. High-intensity areas were seen in 6 (15.0%) and 49 (42.6%) cases in the Universal Protection Method and non-Universal Protection Method groups, respectively (P = .001). Contrastingly, intraprocedural complications were observed in 9 (22.5%) and 21 (18.3%) cases in the Universal Protection Method and non-Universal Protection Method groups, respectively. Among these intraprocedural complication cases, high-intensity areas were observed in 1 case (11.1%) in the Universal Protection Method group and in 15 cases (71.4%) in the non-Universal Protection Method group. Universal Protection Method is a safe technique that is applicable to all patients undergoing carotid artery stenting, irrespective of individual risk factors. Notably, the incidence rates of both distal embolization and unexpected intraprocedural complications are low. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

While transrectal prostate biopsy is the cornerstone of prostate cancer diagnosis, serious post-biopsy infectious complications are reported to be increasing. A better understanding of the true prevalence and microbiology of these events is needed to guide quality improvement in this area and ultimately better early detection practices. Using data from the MUSIC registry we identified all men who underwent transrectal prostate biopsy at 21 practices in Michigan from March 2012 to June 2013. Trained data abstractors recorded pertinent data including prophylactic antibiotics and all biopsy related hospitalizations. Claims data and followup telephone calls were used for validation. All men admitted to the hospital for an infectious complication were identified and their culture data were obtained. We then compared the frequency of infection related hospitalization rates across practices and according to antibiotic prophylaxis in concordance with AUA best practice recommendations. The overall 30-day hospital admission rate after prostate biopsy was 0.97%, ranging from 0% to 4.2% across 21 MUSIC practices. Of these hospital admissions 95% were for infectious complications and the majority of cultures identified fluoroquinolone resistant organisms. AUA concordant antibiotics were administered in 96.3% of biopsies. Patients on noncompliant antibiotic regimens were significantly more likely to be hospitalized for infectious complications (3.8% vs 0.89%, p=0.0026). Infection related hospitalizations occur in approximately 1% of men undergoing prostate biopsy in Michigan. Our findings suggest that many of these events could be avoided by implementing new protocols (eg culture specific or augmented antibiotic prophylaxis) that adhere to AUA best practice recommendations and address fluoroquinolone resistance.

Contemporary Approaches to Perioperative IV Fluid Therapy.

Myles, Paul S; Andrews, Sam; Nicholson, Jonathan; Lobo, Dileep N; Mythen, Monty

2017-10-01

Intravenous fluid therapy is required for most surgical patients, but inappropriate regimens are commonly prescribed. The aim of this narrative review was to provide evidence-based guidance on appropriate perioperative fluid management. We did a systematic literature search of the literature to identify relevant studies and meta-analyses to develop recommendations. Of 275 retrieved articles, we identified 25 articles to inform this review. "Normal" saline (0.9% sodium chloride) is not physiological and can result in sodium overload and hyperchloremic acidosis. Starch colloid solutions are not recommended in surgical patients at-risk of sepsis or renal failure. Most surgical patients can have clear fluids and/or administration of carbohydrate-rich drinks up to 2 h before surgery. An intraoperative goal-directed fluid strategy may reduce postoperative complications and reduce hospital length of stay. Regular postoperative assessment of the patient's fluid status and requirements should include looking for physical signs of dehydration or hypovolemia, or fluid overload. Both hypovolemia and salt and water overload lead to adverse events, complications and prolonged hospital stay. Urine output can be an unreliable indicator of hydration status in the postoperative surgical patient. Excess fluid administration has been linked to acute kidney injury, gastrointestinal dysfunction, and cardiac and pulmonary complications. There is good evidence supporting the avoidance of unnecessary fasting and the value of an individualized perioperative IV fluid regimen, with transition to oral fluids as soon as possible, to help patients recover from major surgery.

The aim of this study was to evaluate the effectiveness and safety of high-frequency linear probe ultrasonographic (US) guidance percutaneous nephrostomy (PN) in terms of diagnostic and therapeutic approach in preschool-age children with urological problems. PN was performed on 40 kidneys in 33 patients (13 girls, 20 boys) aged 3 days - 7 years (mean 4.1 years). All procedures were performed with US guidance utilizing a Shimadzu SDU 2200 Xplus 5-10 mHz probe. Complete blood count, urinalysis, bladder urine culture, blood urea, and creatinine values were obtained before PN placement on the same day. Urine cultures were obtained by nephrostomy tube and compared to bladder urine culture. PN procedures were technically successful in 39 kidney units (97.5%). Two major complications were macroscopic hematuria requiring blood transfusions (1 case) and sepsis (1 case). Minor complications were displacement of the catheter (4), urinary tract infection (4), urine extravasation (1), early dislocation of the catheter (1). In three cases, the catheter was replaced. Analysis of bladder urine showed that 13 patients (39.4%) had positive cultures, but analysis of PN urine showed that 25 patients (78.1%) had positive cultures. PN is an easy, safe and efficient diagnostic and therapeutic procedure with few complications even in preschool-age children. The antibiotic regimen should be revised in order to avoid sepsis and urinary tract infection. Copyright © 2012 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

Liposuction is among the most commonly performed aesthetic procedures, and is being performed increasingly as an adjunct to other procedures. To report the incidence and risk factors of significant complications after liposuction, and to determine whether adding liposuction to other cosmetic surgical procedures impacts the complication risk. A prospective cohort of patients who underwent liposuction between 2008 and 2013 was identified from the CosmetAssure database. Primary outcome was occurrence of major complications requiring emergency room visit, hospital admission, or reoperation within 30 days of the operation. Univariate and multivariate analysis evaluated risk factors including age, gender, body mass index (BMI), smoking, diabetes, type of surgical facility, and combined procedures. Of the 31,010 liposuction procedures, only 11,490 (37.1%) were performed as a solitary procedure. Liposuction alone had a major complication rate of 0.7% with hematoma (0.15%), pulmonary complications (0.1%), infection (0.1%), and confirmed venous thromboembolism (VTE) (0.06%) being the most common. Independent predictors of major complications included combined procedures (Relative Risk (RR) 4.81), age (RR 1.01), BMI (RR 1.05), and procedures performed in hospitals (RR 1.36). When examining specifically other aesthetic procedures performed alone or with liposuction, combined procedures had a higher risk of confirmed VTE (RR 5.65), pulmonary complications (RR 2.72), and infection (RR 2.41), but paradoxically lower hematoma risk (RR 0.77) than solitary procedures. Liposuction performed alone is a safe procedure with a low risk of major complications. Combined procedures, especially on obese or older individuals, can significantly increase complication rates. The impact of liposuction on the risk of hematoma in combined procedures needs further investigation. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this meta-analysis and systematic review was to compare the "early postoperative complication rate i.e. within 30-days" reported from randomized control trials (RCTs) comparing these two procedures. RCTs comparing the early complication rates following LVSG and LRYGB between 2000 and 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included 30-day mortality, major and minor complications and interventions required for their management, length of hospital stay, readmission rates, operating time, and conversions from laparoscopic to open procedures. Six RCTs involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on early major complications. A statistically significant reduction in relative odds of early major complications favoring the LVSG procedure was noted (p = 0.05). Five RCTs representing 633 patients (LVSG n = 317, LRYGB n = 316) reported early minor complications. A non-statically significant reduction in relative odds of 29 % favoring the LVSG procedure was observed for early minor complications (p = 0.4). However, other outcomes directly related to complications which included reoperation rates, readmission rate, and 30-day mortality rate showed comparable effect size for both surgical procedures. This meta-analysis and systematic review of RCTs suggests that fewer early major and minor complications are associated with LVSG compared with LRYGB procedure. However, this does not translate into higher readmission rate, reoperation rate, or 30-day mortality for either procedure.

2016-05-01

Diabetes mellitus has been linked with a variety of perioperative adverse events across surgical disciplines. There is a paucity of studies systematically examining risk factors, including diabetes, and complications of aesthetic surgical procedures. The purpose of this study was to compare incidence and type of complications between diabetic and non-diabetic patients undergoing various aesthetic surgical procedures, to identify specific procedures where diabetes significantly increases risk of complications, and to study diabetes as an independent risk factor for major complications following aesthetic surgery. A prospective cohort of 129,007 patients who enrolled into the CosmetAssure insurance program and underwent cosmetic surgical procedures between May 2008 and May 2013 were reviewed. Diabetes was evaluated as risk factor for major complications, requiring hospital admission, emergency room visit, or a reoperation within 30 days after surgery. Multivariate regression analysis was performed controlling for the effects of age, smoking, obesity, gender, type of procedures, and surgical facility. Overall, 2506 patients (1.9%) had a major complication. Diabetics had significantly more complications compared to non-diabetics (3.1% vs 1.9%, P < 0.01). In univariate analysis, infectious (1.1% vs 0.5%, P < 0.01) and pulmonary (0.3% vs 0.1%, P < 0.01) complications were significantly higher among diabetics. Notably, diabetics had higher risks of complication in body cases (4.3% vs 2.6%, P < 0.01) and specifically abdominoplasty (6.1% vs 3.0%, P < 0.01). In multivariate analysis, diabetes was found to be an independent risk factor of any complication (relative risk 1.31, P = 0.03) and infection (relative risk 1.70, P < 0.01). Diabetes is an independent risk factor of major complications, particularly infection, after aesthetic surgical procedures. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

Contact lens complications.

PubMed

Suchecki, Jeanine K; Donshik, Peter; Ehlers, William H

2003-09-01

Complications associated with contact lenses range from mild to severe and occur with all lens modalities. Contact lens wear can cause a change in corneal physiology, which can lead to epithelial, stromal, and endothelial compromise. Other complications include lens deposition, allergic conjunctivitis, giant papillary conjunctivitis, peripheral infiltrates, microbial keratitis, and neovascularization. Pre-existing conditions can contribute to these complications, or they can occur in association with contact lens wear and care regimens. Patient-related factors, such as alteration of the recommended wearing or replacement schedules and noncompliance with recommended contact lens care regimens for economic reasons, convenience, or in error, contribute to contact lens-related complications and have led to difficulty in accurate determination of complication rates among the various lens wear modalities. Complications may require discontinuation of contact lenses, topical therapy, and changes in contact lens wearing schedules, materials, and care solutions. On initial lens fitting and follow-up evaluations, practitioners should review contact lens replacement and cleaning regimens with patients and discuss complications. To avoid serious complications, patients should be reminded to remove their contact lenses as soon as ocular irritation occurs, and to call their eye care practitioner immediately if symptoms persist.

Abstract Objective We previously demonstrated that parents whose children die in a pediatric intensive care unit (PICU) have a high level of complicated grief symptoms 6 months after the death. In this study, we investigate the change in the extent of complicated grief symptoms among these parents between 6 and 18 months postdeath and identify factors predicting improvement. Methods One hundred thirty-eight parents of 106 children completed surveys at 6 and 18 months. Surveys included the Inventory of Complicated Grief (ICG), measures of grief avoidance, attachment, caregiving and social support, and demographics. Multivariable analysis was performed using generalized estimating equations to identify characteristics independently associated with improvement in ICG score. Results ICG scores were 33.4 ± 13.6 at 6 months and 28.0 ± 13.5 at 18 months, representing an improvement in ICG score of 5.4 + 8.0 (95% confidence interval [CI] 4.1–6.8, p < 0.001). Variables independently associated with greater improvement in ICG score included traumatic death and greater grief avoidance. Variables independently associated with less improvement included being the biological parent and having more responsive caregiving. Parents with one or two surviving children had more improvement in ICG score than those with no surviving children whereas parents with three or more surviving children had less improvement. Conclusion Complicated grief symptoms decrease among parents between 6 and 18 months after their child's death in the PICU; however, high symptom levels persists for some. Better understanding of the trajectory of complicated grief will allow parents at risk for persistent distress to receive professional support. PMID:21281122

Hyper redundant manipulators have a large number of degrees of freedom (DOF) than the required to perform a given task. Additional DOF of manipulators provide the flexibility to work in highly cluttered environment and in constrained workspaces. Inverse kinematics (IK) of hyper-redundant manipulators is complicated due to large number of DOF and these manipulators have multiple IK solutions. The redundancy gives a choice of selecting best solution out of multiple solutions based on certain criteria such as obstacle avoidance, singularity avoidance, joint limit avoidance and joint torque minimization. This paper focuses on IK solution and redundancy resolution of hyper-redundant manipulator using classical optimization approach. Joint positions are computed by optimizing various criteria for a serial hyper redundant manipulators while traversing different paths in the workspace. Several cases are addressed using this scheme to obtain the inverse kinematic solution while optimizing the criteria like obstacle avoidance, joint limit avoidance.

Case series of four dogs in which extensive bite wounds had been treated using octenidine dihydrochloride (Octenivet® or Octenisept®) flushing. The dogs subsequently developed severe local complications. Retrospective evaluation of clinical symptoms, diagnostics, therapy and course of the disease. In four dogs, severe necrosis and persistent edematous changes of the treated area developed after the application of octenidine dihydrochloride. The clinical course was comparable to complications described previously in human medicine. Therapy was protracted and complicated by secondary wound infection. Irrigation of deep wounds, particularly bite wounds, using octenidine dihydrochloride without drainage may lead to persistent edematous changes, inflammatory reactions and necrosis. The inappropriate application of octenidine dihydrochloride for wound irrigation should be avoided in veterinary medicine.

Continent cutaneous diversion.

This article updates the recently reported intermediate to long-term results with the most commonly used forms of continent cutaneous urinary diversion, and to discuss approaches to early and late complications. Many variations on construction of a continent cutaneous diversion have been described. Results with large series of patients demonstrate acceptable results with all of them, but with a significant revision rate. Long-term complication rates and adaptation to robotic approaches have recently been described. Continent cutaneous diversion is rarely offered in the USA to patients undergoing cystectomy except in a few centers. Most studies have found a high complication rate and need for revision surgery in 10-20% of patients. However, functional results are acceptable and many patients are willing to accept the complications in exchange for avoiding an external appliance.

Plasmapheresis it is a therapeutic method based on extracorporeal plasma exchange. First attempts at treatment with plasmapheresis date back to the beginning of the 20th century. However, it was first brought to clinical practice only in the 1950s as a way of treating Waldenstrom macroglobulinemia and in last decades a dynamic improvement in this method has been observed. At the moment plasmapheresis is used in the treatment of over 150 diseases. Like every invasive method, it may cause complications, which are due to anticoagulation, the use of replacement fluids, the technical part of the procedure, and the presence of intravenous catheters. The knowledge of potential complications and the way of preventing them by the medical staff help to avoid complications and to decrease their harmful effects.

Abstract Objective: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. Methods: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. Results: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. Conclusions: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis. PMID:26398760

Coated and uncoated self-expanding metal stents for malignant stenosis in the upper GI tract: preliminary clinical experiences with Wallstents.

1994-09-01

The clinical feasibility of self-expanding metal stents with respect to the technical success, complications, and reintervention rate should be tested. Five coated and 26 uncoated prototype Wallstents, especially designed for stenosis of the upper GI tract, were implanted in 23 patients. All patients with dysphagia suffered from inoperable tumor stenosis of the esophagus or the cardia. Stent implantation was performed under slight i.v. sedoanalgesia. Technical success was achieved in all 31 implanted stents. Forty-eight hr after implantation, dysphagia was improved in 21/23 patients. Acute problems observed within 1 wk were stent migration (1 patient, uncoated stent), oblique position of the stent (3 patients), epigastric or retrosternal pain (9 patients), insufficient stent expansion (4 patients), and pouch formation at the upper rim of the stent (4 patients). An uncomplicated follow-up (median 66 days, range 10-139 days) was seen in 12 patients (52%). Major problems in the follow-up period were stent migration in three patients (three coated stents, two stent migrations in one patient) and stent obstruction by tumor ingrowth/overgrowth and/or food impaction in eight patients (35%). Most of these problems could be successfully resolved by implantation of a second stent or electrocoagulation of overgrowing tumor tissue. By the 1st of March, 1994, three patients were still alive with a follow-up period of 530 days (median range, 336-880 days); 20 patients were decreased with a follow-up period of 70 days (median range, 3-374 days). Implantation of esophageal Wallstents is safe and has a low risk of acute complications and mortality for the patient. Early complications such as perforation and bleeding did not occur. Tumor ingrowth/overgrowth are the major reasons for the high reintervention rate in the follow-up period. Coated stents can resolve this problem, provided that stent migration can be avoided by improvement of the coating technology.

Technical pitfalls and tips for the valve-in-valve procedure

PubMed Central

2017-01-01

Transcatheter aortic valve implantation (TAVI) has emerged as a viable treatment modality for patients with severe aortic valve stenosis and multiple co-morbidities. More recent indications include the use of transcatheter heart valves (THV) to treat degenerated bioprosthetic surgical heart valves (SHV), which are failing due to stenosis or regurgitation. Valve-in-valve (VIV) procedures in the aortic position have been performed with a variety of THV devices, although the balloon-expandable SAPIEN valve platform (Edwards Lifesciences Ltd, Irvine, CA, USA) and self-expandable CoreValve platform (Medtronic Inc., MN, USA) have been used in majority of the patients. VIV treatment is appealing as it is less invasive than conventional surgery but optimal patient selection is vital to avoid complications such as malposition, residual high gradients and coronary obstruction. To minimize the risk of complications, thorough procedural planning is critical. The first step is identification of the degenerated SHV, including its model, size, fluoroscopic appearance. Although label size and stent internal diameter (ID) are provided by the manufacturer, it is important to note the true ID. The true ID is the ID of a SHV after the leaflets are mounted and helps determine the optimal size of THV. The second step is to determine the type and size of the THV. Although this is determined in the majority of the cases by user preference, in certain situations one THV may be more suitable than another. As the procedure is performed under fluoroscopy, the third step is to become familiarized with the fluoroscopic appearance of both the SHV and THV. This helps to determine the landmarks for optimal positioning, which in turn determines the gradients and fixation. The fourth step is to assess the risk of coronary obstruction. This is performed with either aortic root angiography or ECG-gated computerised tomography (CT). Finally, the route of approach must be carefully planned. Once these aspects are addressed, the procedure can be performed efficiently with a low risk of complications. PMID:29062752

Background Hypophosphataemia after a hepatectomy suggests hepatic regeneration. It was hypothesized that the absence of hypophosphataemia is associated with post-operative hepatic insufficiency (PHI) and complications. Methods Patients who underwent a major hepatectomy from 2000–2012 at a single institution were identified. Post-operative serum phosphorus levels were assessed. Primary outcomes were PHI (peak bilirubin >7 mg/dl), major complications, and 30- and 90-day mortality. Results Seven hundred and nineteen out of 749 patients had post-operative phosphorus levels available. PHI and major complications occurred in 63 (8.8%) and 169 (23.5%) patients, respectively. Thirty- and 90-day mortality were 4.0% and 5.4%, respectively. The median phosphorus level on post-operative-day (POD) 2 was 2.2 mg/dl; 231 patients (32.1%) had phosphorus >2.4 on POD2. Patients with POD2 phosphorus >2.4 had a significantly higher incidence of PHI, major complications and mortality. On multivariate analysis, POD2 phosphorus >2.4 remained a significant risk factor for PHI [(hazard ratio HR):1.78; 95% confidence interval (CI):1.02–3.17; P = 0.048], major complications (HR:1.57; 95%CI:1.02–2.47; P = 0.049), 30-day mortality (HR:2.70; 95%CI:1.08–6.76; P = 0.034) and 90-day mortality (HR:2.51; 95%CI:1.03–6.15; P = 0.044). Similarly, patients whose phosphorus level reached nadir after POD3 had higher PHI, major complications and mortality. Conclusion Elevated POD2 phosphorus levels >2.4 mg/dl and a delayed nadir in phosphorus beyond POD3 are associated with increased post-operative hepatic insufficiency, major complications and early mortality. Failure to develop hypophosphataemia within 72 h after a major hepatectomy may reflect insufficient liver remnant regeneration. PMID:24830898

2013-09-01

A comparison of 2 methods of early-onset scoliosis treatment using radiographic measures and complication rates. To determine whether a delaying tactic (serial casting) has comparable efficacy to a surgical method (insertion of growing rod instrumentation [GRI]) in the initial phase of early-onset deformity management. Serial casts are used in experienced centers to delay operative management of curves of surgical magnitude (greater than 50°) in children up to age 6 years. A total of 27 casted patients from 3 institutions were matched with 27 patients from a multicenter database according to age (within 6 months of each other), curve magnitude (within 10° of each other), and diagnosis. Outcomes were compared according to major curve magnitude, spine length (T1-S1), duration and number of treatment encounters, and complications. There was no difference in age (5.5 years) or initial curve magnitude (65°) between groups, which reflects the accuracy of the matching process. Six pairs of patients had neuromuscular diagnoses, 11 had idiopathic deformities, and 10 had syndromic scoliosis. Growing rod instrumentation patients had smaller curves (45.9° vs. 64.9°; p = .002) at follow-up, but there was no difference in absolute spine length (GRI = 32.0 cm; cast = 30.6 cm; p = .26), even though GRI patients had been under treatment for a longer duration (4.5 vs. 2.4 years; p < .0001) and had undergone a mean of 5.5 lengthenings compared with 4.0 casts. Growing rod instrumentation patients had a 44% complication rate, compared with 1 cast complication. Of 27 casted patients, 15 eventually had operative treatment after a mean delay of 1.7 years after casting. Cast treatment is a valuable delaying tactic for younger children with early-onset scoliosis. Spine deformity is adequately controlled, spine length is not compromised, and surgical complications associated with early GRI treatment are avoided. Copyright © 2013 Scoliosis Research Society.

INTRODUCTION To avoid the risk of complications of biliary drainage, a feasibility study was carried out to determine whether it might be possible to fast-track surgical treatment, with resection before biliary drainage, in jaundiced patients with proximal pancreatic/peri-ampullary malignancy. PATIENTS AND METHODS Over an 18-month period, based on their presenting bilirubin levels and other logistical factors, all jaundiced patients who might be suitable for fast-track management were identified. Data on complications and hospital stay were compared with those patients in whom a conventional pathway (with biliary drainage) was used during the same time period. Data were also compared with a group of patients from the preceding 6 months. RESULTS Nine patients were fast-tracked and 49 patients treated in the conventional pathway. Fast-track patients mean (SD) serum bilirubin level was 265 μmol/l (81.6) at the time of the operation compared to 43 μmol/l (51.3; P ≥ 0.0001) in conventional patients. Mean (SD) of time from referral to operation, 14 days (9) versus 59 days (36.9), was significantly shorter in fast-track patients than conventional patients (P ≤ 0.0001). Length of hospital stay mean (SD) at 17 (6) days versus 22 days (19.6; P = 0.2114), surgical complications and mortality in fast-track patients were similar to conventional patients. Prior to surgery, the 49 conventional patients underwent a total of 73 biliary drainage procedures resulting in seven major complications. Comparison with the group of patients from the previous 6 months indicated that the conventional group were not disadvantaged. CONCLUSIONS Fast-track management by resection without biliary drainage of selected patients with distal biliary strictures is safe and has the potential to reduce the waiting time to surgery, overall numbers of biliary drainage procedures and the complications thereof.

This paper reviews the latest evidence for local and systemic interventions for the prevention of alveolar osteitis (dry socket). Dry socket is a painful and common post-operative complication following exodontia. Any interventions for the prevention of dry socket could reduce both its incidence and help avoid this painful complication. Prophylactic measures proposed in the literature are discussed. Furthermore, this article discusses both the clinical and histological stages of a normal healing socket.

Decision Support from Genetic Algorithms for Ship Collision Avoidance Route Planning and Alerts

Tsou, Ming-Cheng; Kao, Sheng-Long; Su, Chien-Min

When an officer of the watch (OOW) faces complicated marine traffic, a suitable decision support tool could be employed in support of collision avoidance decisions, to reduce the burden and greatly improve the safety of marine traffic. Decisions on routes to avoid collisions could also consider economy as well as safety. Through simulating the biological evolution model, this research adopts the genetic algorithm used in artificial intelligence to find a theoretically safety-critical recommendation for the shortest route of collision avoidance from an economic viewpoint, combining the international regulations for preventing collisions at sea (COLREGS) and the safety domain of a ship. Based on this recommendation, an optimal safe avoidance turning angle, navigation restoration time and navigational restoration angle will also be provided. A Geographic Information System (GIS) will be used as the platform for display and operation. In order to achieve advance notice of alerts and due preparation for collision avoidance, a Vessel Traffic Services (VTS) operator and the OOW can use this system as a reference to assess collision avoidance at present location.

In the mandatory nationwide Dutch Pancreatic Cancer Audit, rates of major complications and Failure to Rescue (FTR) after pancreatoduodenectomy between low- and high-mortality hospitals are compared, and independent predictors for FTR investigated. Patients undergoing pancreatoduodenectomy in 2014 and 2015 in The Netherlands were included. Hospitals were divided into quartiles based on mortality rates. The rate of major complications (Clavien-Dindo ≥3) and death after a major complication (FTR) were compared between these quartiles. Independent predictors for FTR were identified by multivariable logistic regression analysis. Out of 1.342 patients, 391 (29%) developed a major complication and in-hospital mortality was 4.2%. FTR occurred in 56 (14.3%) patients. Mortality was 0.9% in the first hospital quartile (4 hospitals, 327 patients) and 8.1% in the fourth quartile (5 hospitals, 310 patients). The rate of major complications increased by 40% (25.7% vs 35.2%) between the first and fourth hospital quartile, whereas the FTR rate increased by 560% (3.6% vs 22.9%). Independent predictors of FTR were male sex (OR = 2.1, 95%CI 1.2-3.9), age >75 years (OR = 4.3, 1.8-10.2), BMI ≥30 (OR = 2.9, 1.3-6.6), histopathological diagnosis of periampullary cancer (OR = 2.0, 1.1-3.7), and hospital volume <30 (OR = 3.9, 1.6-9.6). Variations in mortality between hospitals after pancreatoduodenectomy were explained mainly by differences in FTR, rather than the incidence of major complications.

A large national surgical registry was used to establish national benchmarks and associated predictors of major neurologic complications (i.e., coma and stroke) after surgical clipping of unruptured intracranial aneurysms. The American College of Surgeons National Surgical Quality Improvement Program data set between 2007 and 2013 was used for this retrospective cohort analysis. Demographic, comorbidity, and operative characteristics associated with the development of a major neurologic complication (i.e., coma or stroke) were elucidated using a backward selection stepwise logistic regression analysis. This model was subsequently used to fit a predictive score for major neurologic complications. Inclusion criteria were met by 662 patients. Of these patients, 57 (8.61%) developed a major neurologic complication (i.e., coma or stroke) within the 30-day postoperative period. On multivariable analysis, operative time (log odds 0.004 per minute; 95% confidence interval [CI], 0.002-0.007), age (log odds 0.05 per year; 95% CI, 0.02-0.08), history of chronic obstructive pulmonary disease (log odds 1.26; 95% CI, 0.43-2.08), and diabetes (log odds 1.15; 95% CI, 0.38-1.91) were associated with an increased odds of major neurologic complications. When patients were categorized according to quartile of a predictive score generated from the multivariable analysis, rates of major neurologic complications were 1.8%, 4.3%, 6.7%, and 21.2%. Using a large, national multi-institutional cohort, this study established representative national benchmarks and a predictive scoring system for major neurologic complications following operative management of unruptured intracranial aneurysms. The model may assist with risk stratification and tailoring of decision making in surgical candidates. Copyright © 2016 Elsevier Inc. All rights reserved.

Previous studies reported conflicting evidence on the effects of obesity on outcomes after gastrointestinal surgery. The aims of this study were to explore the relationship of obesity with major post-operative complications in an international cohort and to present a meta-analysis of all available prospective data. This prospective, multi-centre study included adults undergoing both elective and emergency gastrointestinal resection, reversal of stoma, or formation of stoma. The primary endpoint was 30-day major complications (Clavien-Dindo grades III-V). A systematic search was undertaken for studies assessing the relationship between obesity and major complications after gastrointestinal surgery. Individual patient meta-analysis (IPMA) was used to analyse pooled results. This study included 2519 patients across 127 centres, of whom 560 (22.2%) were obese. Unadjusted major complication rates were lower in obese versus normal weight patients (13.0% versus 16.2%, respectively), but this did not reach statistical significance (p=0.863) on multivariate analysis for patients having surgery for either malignant or benign conditions. IPMA demonstrated that obese patients undergoing surgery for malignancy were at increased risk of major complications (odds ratio 2.10, 95% confidence interval 1.49-2.96, p<0.001), whereas obese patients undergoing surgery for benign indications were at decreased risk (OR 0.59, 95% CI 0.46-0.75, p<0.001), compared to normal weight patients. In our international data, obesity was not found to be associated with major complications following gastrointestinal surgery. Meta-analysis of available prospective data made a novel finding of obesity being associated with different outcomes depending on whether patients were undergoing surgery for benign or malignant disease.

In daily practice, acute and chronic pulmonary diseases are common issues presenting to the anesthetist. Respiratory physiology in general is affected by both general and regional anesthesia, which results in an increased number of perioperative complications in pulmonary risk patients. Therefore, anesthetic management of patients with bronchial asthma needs to address different clinical topics: the physical appearance of pulmonary disease, type and extent of surgical intervention as well as effects of therapeutic drugs, anesthetics and mechanical ventilation on respiratory function. The present work describes important precautions in preoperative scheduling of the asthmatic patient. In the operative course, airway manipulation and a number of anesthetics are able to trigger intraoperative bronchial spasm with possibly fatal outcome. It is essential to avoid these substances to prevent asthma attack. If asthmatic status occurs, appropriate procedures according to therapeutic standards have to be applied to the patient. Postoperatively, sufficient pain therapy avoids pulmonary complications and improves outcome. © Georg Thieme Verlag Stuttgart · New York.

Mini-open lateral retroperitoneal lumbar spine approach using psoas muscle retraction technique. Technical report and initial results on six patients.

2013-09-01

The main aim of this paper was to report reproducible method of lumbar spine access via a lateral retroperitoneal route. The authors conducted a retrospective analysis of the technical aspects and clinical outcomes of six patients who underwent lateral multilevel retroperitoneal interbody fusion with psoas muscle retraction technique. The main goal was to develop a simple and reproducible technique to avoid injury to the lumbar plexus. Six patients were operated at 15 levels using psoas muscle retraction technique. All patients reported improvement in back pain and radiculopathy after the surgery. The only procedure-related transient complication was weakness and pain on hip flexion that resolved by the first follow-up visit. Psoas retraction technique is a reliable technique for lateral access to the lumbar spine and may avoid some of the complications related to traditional minimally invasive transpsoas approach.

Oriental upper blepharoplasty.

Weng, Chau-Jin

2009-02-01

Aesthetic surgery of the upper eyelids is a very common procedure performed in cosmetic practices around the world. The word blepharoplasty, however, has a different meaning in Asia than it does elsewhere. Orientals have different periorbital anatomic characteristics, their motivations for seeking eyelid treatment are different, and operative techniques have been adapted consequently. There are also many eyelid shapes among Orientals, mostly with regard to the presence and location of the supratarsal fold and/or presence of an epicanthal fold. The surgeon must therefore master a range of surgical procedures to treat these variations adequately. It is critical to know the indications for each blepharoplasty technique as well as their complications to select the right surgery and avoid unfavorable results. Epicanthoplasty performed on the right patient can greatly improve aesthetic results while retaining ethnic characteristics. This article will discuss Oriental eyelid characteristics, preoperative patient assessment, commonly used corrective techniques for the "double-eyelid" creation, and complications and how to avoid them.

The mortality rate of horses undergoing general anaesthesia is high when compared to humans or small animal patients. One of the most critical periods during equine anaesthesia is recovery, as the horse attempts to regain a standing position. This study was performed in a private equine practice in Belgium that uses a purpose-designed one-man (head and tail) rope recovery system to assist the horse during the standing process.The main purpose of the retrospective study was to report and analyse complications and the mortality rate in horses during recovery from anaesthesia using the described recovery system. Information retrieved from the medical records included patient signalment, anaesthetic protocol, duration of anaesthesia, ASA grade, type of surgery, recovery time and complications during recovery. Sedation was administered to all horses prior to recovery with the rope system. Complications were divided into major complications in which the horse was euthanized and minor complications where the horse survived. Major complications were further subdivided into those where the rope system did not contribute to the recovery complication (Group 1) and those where it was not possible to determine if the rope system was of any benefit (Group 2). Five thousand eight hundred fifty two horses recovered from general anaesthesia with rope assistance. Complications were identified in 30 (0.51%). Major complications occurred in 12 horses (0.20%) of which three (0.05%) were assigned to Group 1 and nine (0.15%) to Group 2. Three horses in Group 2 suffered musculoskeletal injuries (0.05%). Eighteen horses (0.31%) suffered minor complications, of which five (0.08%) were categorised as failures of the recovery system. This study reports the major and minor complication and mortality rate during recovery from anaesthesia using a specific type of rope recovery system. Mortality associated with the rope recovery system was low. During recovery from anaesthesia this rope system may reduce the risk of lethal complications, particularly major orthopaedic injuries.

During surgery, peripheral nerves are often seen to follow unpredictable paths because of previous surgeries and/or compression caused by a tumor. Iatrogenic nerve injury is a serious complication that must be avoided, and preoperative evaluation of nerve paths is important for preventing it. In this study, transcutaneous electrical nerve stimulation (TENS) was used for an in-depth analysis of peripheral nerve paths. This study included 27 patients who underwent the TENS procedure to evaluate the peripheral nerve path (17 males and 10 females; mean age: 59.9 years, range: 18-83 years) of each patient preoperatively. An electrode pen coupled to an electrical nerve stimulator was used for superficial nerve mapping. The TENS procedure was performed on patients' major peripheral nerves that passed close to the surgical field of tumor resection or trauma surgery, and intraoperative damage to those nerves was apprehensive. The paths of the target nerve were detected in most patients preoperatively. The nerve paths of 26 patients were precisely under the markings drawn preoperatively. The nerve path of one patient substantially differed from the preoperative markings with numbness at the surgical region. During surgery, the nerve paths could be accurately mapped preoperatively using the TENS procedure as confirmed by direct visualization of the nerve. This stimulation device is easy to use and offers highly accurate mapping of nerves for surgical planning without major complications. The authors conclude that TENS is a useful tool for noninvasive nerve localization and makes tumor resection a safe and smooth procedure.

A 26-year-old man presented with ipsilateral femur and ankle fractures. The patient was treated with interlocking nail of his femur fracture, followed by open reduction and internal fixation of his ankle fracture under tourniquet control. Postoperatively, the patient developed compartment syndrome of his thigh with elevated pressures, requiring decompressive fasciotomies. This case illustrates the possible complication of treating a femur fracture with intramedullary nailing and then immediately applying a tourniquet to treat an ipsilateral extremity fracture. Because of the complication with this patient, we feel the procedure should be staged, or a tourniquet should be avoided if possible.

To compare complication rates and tube performance of percutaneous mushroom gastrostomy, balloon gastrostomy, and gastrojejunostomy. Between September 9, 1999 and April 23, 2001, 203 patients underwent 250 radiologically guided percutaneous gastrostomy and gastrojejunostomy procedures. Follow-up was conducted through chart reviews and review of our interventional radiology database. Procedural and catheter-related complications were recorded. Chi-square statistical analysis was performed. In patients receiving mushroom-retained gastrostomy catheters (n = 114), the major complication rate was 0.88% (n = 1), the minor complication rate was 5.3% (n = 6), and the tube complication rate was 4.4% (n = 5). In patients receiving balloon-retained gastrostomymore » tubes (n = 67), the major complication rate was 0, the minor complication rate was 4.5% (n = 3), and the tube complication rate was 34.3% (n = 23). In patients receiving gastrojejunostomy catheters (n = 69), the major complication rate was 1.4% (n = 1), the minor complication rate was 2.9% (n = 2), and the tube complication rate was 34.8% (n = 24). No statistically significant differences were found between procedural or peri-procedural complications among the different types of tubes. Mushroom-retained catheters had significantly fewer tube complications (p < 0.01). Percutaneous gastrostomy and gastrojejunostomy have similar procedural and peri-procedural complication rates. Mushroom gastrostomy catheters have fewer tube-related complications compared with balloon gastrostomy and gastrojejunostomy catheters. In addition, mushroom-retained catheters exhibit the best overall long-term tube patency and are therefore the gastrostomy catheter of choice.« less

To evaluate the relationship between surgeon volume of radical cystectomy (RC) and postoperative morbidity, and to assess the economic burden of bladder cancer in the USA. We captured all patients who underwent RC (International Classification of Diseases, ninth revision, code 57.71) between 2003 and 2010, using a nationwide hospital discharge database. Patient, hospital and surgical characteristics were evaluated. The annual volume of RCs performed by the surgeons was divided into quintiles. Multivariable regression models were developed, adjusting for clustering and survey weighting, to evaluate the outcomes, including 90-day major complications (Clavien grade III-V) and direct patient costs. We adjusted for clustering and weighting to achieve a nationally representative analysis. The weighted cohort included 49,792 patients who underwent RC, with an overall 90-day major complication rate of 16.2%. Compared with surgeons performing one RC annually, surgeons performing ≥7 RCs each year had 45% lower odds of major complications (odds ratio [OR] 0.55; P < 0.001) and lower costs by $1690 (P = 0.02). Results were consistent when we analysed surgeon volume as a continuous variable and when we examined the surgeons with the highest volumes (≥28 cases annually), which showed markedly lower odds of major complications compared with the surgeons with the lowest volumes (OR 0.45, 95% CI 0.31-0.67; P < 0.001). Compared with patients who did not have any complications, those who had a major complication were associated with significantly higher 90-day median direct hospital costs ($43,965 vs $24,341; P < 0.001). We showed that there was an inverse relationship between surgeon volume and the development of postoperative 90-day major complication rates as well as direct hospital costs. Centralisation of RC to surgeons with higher volumes may reduce the development of postoperative major complications, thereby decreasing the burden of bladder cancer on the healthcare system. © 2014 The Authors.

Sclerotherapy is one treatment option for head and neck venous malformations (VMs). Evaluation of complication risks is, however, essential to improve its safety. We aimed to systematically report sclerotherapy complications by means of the Clavien-Dindo classification and to distinguish factors predisposing to complications. We identified our institution's head and neck VM patients who received sclerotherapy between 1 January 2007 and 31 August 2013, analyzed patient reports retrospectively, and applied to them the Clavien-Dindo classification. Our 75 VM patients underwent a total of 150 sclerotherapy sessions. The most common sclerosants were 3 % sodium tetradecyl sulfate and polidocanol. Complications occurred in 13 patients (17.3 %) and in 15 sessions (10.0 %); 3 complications required extensive postprocedural treatment and caused permanent morbidity, whereas 12 received conservative treatment. Patients with sclerotherapy complications underwent more treatments (p = 0.009) and more often needed further surgery (p = 0.007). We thus consider sclerotherapy a relatively safe treatment modality for head and neck VMs. To avoid complications, evaluation of VM characteristics and optimal treatment technique in a multidisciplinary team is vital.

To assess the impact of postoperative complications on full in-hospital costs per case. Rising expenses for complex medical procedures combined with constrained resources represent a major challenge. The severity of postoperative complications reflects surgical outcomes. The magnitude of the cost created by negative outcomes is unclear. Morbidity of 1200 consecutive patients undergoing major surgery from 2005 to 2008 in a tertiary, high-volume center was assessed by a validated, complication score system. Full in-hospital costs were collected for each patient. Statistical analysis was performed using a multivariate linear regression model adjusted for potential confounders. This study population included 393 complex liver/bile duct surgeries, 110 major pancreas operations, 389 colon resections, and 308 Roux-en-Y gastric bypasses. The overall 30-day mortality rate was 1.8%, whereas morbidity was 53.8%. Patients with an uneventful course had mean costs per case of US$ 27,946 (SD US$ 15,106). Costs increased dramatically with the severity of postoperative complications and reached the mean costs of US$ 159,345 (SD US$ 151,191) for grade IV complications. This increase in costs, up to 5 times the cost of a similar operation without complications, was observed for all types of investigated procedures, although the magnitude of the increase varied, with the highest costs in patients undergoing pancreas surgery. This study demonstrates the dramatic impact of postoperative complications on full in-hospital costs per case and that complications are the strongest indicator of costs. Furthermore, the study highlights a relevant savings capacity for major surgical procedures, and supports all efforts to lower negative events in the postoperative course.

Preoperative Nutritional Status as an Adjunct Predictor of Major Postoperative Complications Following Anterior Cervical Discectomy and Fusion.

Retrospective analysis of the National Surgical Quality Improvement Program (NSQIP), a prospectively collected multicenter surgical outcomes database. To determine the effect of preoperative nutritional status, as measured by serum albumin concentration, on outcomes following anterior cervical discectomy and fusion (ACDF). Nutritional status has been shown to be an important predictor of postoperative recovery and outcomes. Serum albumin concentration is an established marker of overall nutrition and systemic disease, however, its correlation to outcomes following ACDF is unknown. ACDF cases from 2005 to 2010 were identified in the NSQIP and categorized by preoperative serum albumin: normal (≥3.5 g/dL), hypoalbuminemic (<3.5 g/dL), or not measured. Independent demographic and comorbidity variables were assessed, including American Society of Anesthesiologists (ASA) classification. Risk factors for major postoperative complications were identified, including preoperative hypoalbuminemia, and incorporated into a multivariable logistic regression model to determine the strength of preoperative hypoalbuminemia as an adjusted predictor of major postoperative complications. There were 3671 ACDF cases, of which 1382 (37.6%) had preoperative albumin measurements. Patients with albumin measurements were older and more likely to have higher ASA class, hypertension, and diabetes. Hypoalbuminemic patients had higher rates of having any major postoperative complication(s), specifically pulmonary complications, cardiac complications, and reoperation, relative to those with normal albumin (all P<0.01). These patients also had longer lengths of stay (5.0 vs. 1.9 d). With multivariable regression, preoperative hypoalbuminemia was a strong independent predictor of major postoperative complications, with an adjusted odds ratio of 3.37 (P=0.003). In this analysis of a prospective surgical outcomes database, preoperative serum hypoalbuminemia was an important adjunct predictor of major complications following ACDF. In high-risk patients with multiple medical comorbidities, we recommend that clinicians consider nutritional screening and optimization as part of preoperative risk assessment.

The aim of this study is to evaluate the efficacy and safety of interventional radiology procedures in the treatment of major urological complications after kidney transplantation. Between 2000 and 2010, 1,146 kidney transplants were performed at our institution. A total of 146 major complications occurred, including 77 obstructions, 36 leaks and 33 associated perigraft fluid collections. Percutaneous treatment was carried out in 118/146 complications in 91 patients. In the case of stenosis-obstruction and fistulas (104 complications), the first therapeutic step was placement of a nephrostomy catheter, followed by balloon ureteroplasty, placement of external-internal catheters and double-J stents; 14/33 collections were drained under ultrasound guidance. In all 118 percutaneous interventions, we were able to place a nephrostomy or drainage catheter, with a technical success rate of 100 %. The long-term success rate was 49.6 %: in 57/115 (three patients were lost to follow-up) we obtained the complete resolution of the complication. The procedure-related mortality rate was 0 %. There was only one major complication and the rate of minor complications was 14.4 %. Interventional radiology is the first choice option in the treatment of urological complications after kidney transplantation.

The quality of surgical care in the Veterans Health Administration improved markedly in the 1990s after implementation of the Veterans Affairs (VA) National Surgical Quality Improvement Program (now called the VA Surgical Quality Improvement Program). Although there have been many recent evaluations of surgical care in the private sector, to date, a contemporary global evaluation has not been performed within the VA health system. To provide a contemporaneous report of noncardiac postoperative outcomes in the VA health system during the past 15 years. A retrospective cohort study was conducted using data from the VA Surgical Quality Improvement Program among veterans who underwent inpatient general, vascular, thoracic, genitourinary, neurosurgical, orthopedic, or spine surgery from October 1, 1999, through September 30, 2014. Rates of 30-day morbidity, mortality, and failure to rescue (FTR) over time. Among 704 901 patients (mean [SD] age, 63.7 [11.8] years; 676 750 [96%] male) undergoing noncardiac surgical procedures at 143 hospitals, complications occurred in 97 836 patients (13.9%), major complications occurred in 66 816 (9.5%), FTR occurred in 12 648 of the 97 836 patients with complications (12.9%), FTR after major complications occurred in 12 223 of the 66 816 patients with major complications (18.3%), and 18 924 patients (2.7%) died within 30 days of surgery. There were significant decreases from 2000 to 2014 in morbidity (8202 of 59 421 [13.8%] vs 3368 of 32 785 [10.3%]), major complications (5832 of 59 421 [9.8%] vs 2284 of 32 785 [7%]), FTR (1445 of 8202 [17.6%] vs 351 of 3368 [10.4%]), and FTR after major complications (1388 of 5832 [23.8%] vs 343 of 2284 [15%]) (trend test, P < .001 for all). Although there were no clinically meaningful differences in rates of complications and major complications across hospital risk-adjusted mortality quintiles (any complications: lowest quintile, 20 945 of 147 721 [14.2%] vs highest quintile, 18 938 of 135 557 [14%]; major complications: lowest quintile, 14 044 of 147 721 [9.5%] vs highest quintile, 12 881 of 135 557 [9.5%]), FTR rates (any complications: lowest quintile, 2249 of 20 945 [10.7%] vs highest quintile, 2769 of 18 938 [14.6%]; major complications: lowest quintile, 2161 of 14 044 [15.4%] vs highest quintile, 2663 of 12 881 [20.7%]) were significantly higher with increasing quintile (P < .001). However, across hospital quintiles, there were significant decreases in morbidity (20.6%-29.9% decrease; trend test, P < .001 for all) and FTR (29.2%-50.6% decrease; trend test, P < .001 for all) during the study period. After hierarchical modeling, the odds of postoperative mortality, FTR, and FTR after a major complication were approximately 40% to 50% lower in the most recent study year compared with 15 years ago (P < .001 for all). For the past 15 years, morbidity, mortality, and FTR have improved within the VA health system. Other integrated health systems providing a high volume of surgical care for their enrollees may benefit by critically evaluating the system-level approaches of the VA health system to surgical quality improvement.

The ingestion of a foreign body is one of the most common endoscopic emergencies. Foreign bodies in the upper gastrointestinal tract should be extracted as soon as possible to avoid serious complications such as perforation o bleeding. However, removals of foreign bodies with sharp edges are very difficult and can develop complications during their removal. Various devices have therefore been developed to prevent mucosal injury from the sharp edges during endoscopic extraction. We report a new technique for the successful foreign body extraction of upper digestive tract using the cap from six shooter variceal banding reused. We present 17 cases (9 males and 8 females). The types of foreign bodies removed were: chicken bones (n:7), fish bones (n:3), denture prosthesis (n:2), food bolus (n:2), long pin (n:1), golden thumb tack (n: 1) and press-through package (n:1). There were no complications. This new technique is safe and effective. Highlights its advantages: enhanced sight pharyngo esophageal junction, foreign bodies disimpact at that level, food bolus suck, avoid sharp object damage mucosal or scope and decrease time removal.

Preventing secondary infections among HIV-positive persons.

Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. PMID:1910184

Awake craniotomy (AC) with electrical cortical stimulation has become popular during the last ten years although the basic principles were introduced almost 50 years ago. The aim of this paper is to share with the readers our experience in 25 patients who underwent AC with electrical stimulation. Twenty-five patients who underwent AC between 2010 and 2013 are the subjects of this paper. All patients were diagnosed with intraaxial lesions involving the functional area itself or very close to it by preoperative imaging. During surgery, the functional area was demonstrated by cortical electrical stimulation and resection aimed to preserve it in order to avoid an irreversible functional deficit. Total resection was possible in 80% while in 20% subtotal resection had to be performed because of involvement of the functional area itself. The neurological complication rate was found to be 16% (4 patients) and all were transient. No complication regarding anesthesia was noted. Awake craniotomy in selected patients is very effective, safe and practical for supratentorial lesions close to the eloquent area. Complications related to the surgery itself are uncommon and general anesthesia is avoided. The hospital stay including the intensive care unit is short which makes it very economical surgical procedure.

Transforaminal lumbar interbody fusion (TLIF) is an effective treatment for patients with degenerative lumbar disc disorder. Contralateral radiculopathy, as a complication of TLIF, has been recognized in this institution, but is rarely reported in the literature. In this article, we report 2 cases of contralateral radiculopathy after TLIF in our institution and its associated complications. In the 2 cases, the postoperative computed tomography (CT) and magnetic resonance image (MRI) showed obvious upward movement of the superior articular process, leading to contralateral foraminal stenosis. Revision surgery was done at once to partially resect the opposite superior facet and to relieve nerve root compression. After revision surgery, the contralateral radiculopathy disappeared. Contralateral radiculopathy is an avoidable potential complication. It is very important to create careful preoperative plans and to conscientiously plan the use of intraoperative techniques. In case of postoperative contralateral leg pain, the patients should be examined by CT and MRI. If CT and MRI show that the superior articular process significantly migrated upwards, which leads to contralateral foraminal stenosis, revision surgery should be done at once to partially resect the contralateral superior facet so as to relieve nerve root compression and avoid possible long-term impairment.

INTRODUCTION We describe our technique of percutaneous suprapubic catheter insertion with special reference to steps that help to avoid common complications of haematuria and catheter misplacement. METHODS The procedure is performed using a stainless steel reusable trocar under local infiltrative anaesthesia, usually at the bedside. After clinical confirmation of a full bladder, the trocar is advanced into the bladder through a skin incision. Once the bladder is entered, the obturator is removed and the assistant inserts a Foley catheter followed by rapid balloon inflation. Slight traction is applied to the catheter for about five minutes. Patients with previous lower abdominal surgery, an inadequately distended bladder or acute pelvic trauma do not undergo suprapubic catheterisation using this method. RESULTS The procedure was performed in 72 men (mean age: 42.4 years, range: 18–78 years) with urinary retention with a palpable bladder. The average duration of the procedure was less than five minutes. No complications were noted in any of the patients. CONCLUSIONS Trocar suprapubic catheter insertion is a safe and effective bedside procedure for emergency bladder drainage and can be performed by resident surgeons. The common complications associated with the procedure can be avoided with a few careful steps. PMID:23131233

Conservative management in ureteric hydronephrosis due to deep endometriosis: Could the levonorgestrel-intrauterine device be an option?

Endometriosis can affect up to 10% of women of reproductive age, in a wide range of clinical presentations that vary from mild to severe or deep endometriosis. Deep endometriosis can affect the urinary tract in 1-5% to 15-25% cases. Even though deep endometriosis' surgeries are usually complex with higher rate of complications, conservative management is not always considered as an option because of its high failure rates. This paper describes two cases of deep endometriosis with ureteric involvement (hydronephrosis) treated conservatively with a double-pigtail stent plus a Levonorgestrel intrauterine device, after conservative surgery, who remained symptom free with no evidence of recurrence at 3 years follow-up, avoiding radical high-risk surgery. Impact statement Several treatments have been described for endometriosis. From a symptomatic perspective, conservative medical management has been proposed with a variable response. Concerning deep endometriosis (affecting the urinary or digestive tract), the definitive treatment has always been thought to be radical surgery. However, this can lead to several complications. To illustrate a possible more conservative approach this paper describes two cases of deep infiltrating endometriosis affecting the ureter, treated conservatively with a temporary pigtail ureter stent plus a Levonorgestrel intrauterine device. The management demonstrates that, in a selected population, conservative treatment solves the urinary disease avoiding the surgical complications and, what is more, improving patients' symptoms in a permanent way. Further prospective studies are needed to confirm whether the introduction of this management in clinical practice would reduce the need for surgery thereby, avoiding high-risk surgery and improving the success rate of conservative management.

Electrolyte abnormalities are common in the severely burned patient. There is little information with regard to the frequency and magnitude of hypomagnesemia, as well as on risk factors for this condition. We performed an observational, retrospective analysis of 35 burned patients treated at the Plastic and Reconstructive Surgery Service at the Hospital Central Sur PEMEX, Mexico City. We determined serum magnesium behavior and divided patients into two groups: the first included 11 patients with burns and hypomagnesemia, and the second, 24 patients with burns but without hypomagnesemia. Risk factor identification was performed. We found patient at risk was the one with more than 40% of 2nd or 3rd degree total burned body area, in day 4 or 10 after the burn, and with hypokalemia, hypocalcemia, or both, and without intravenous (i.v.) supplementation of magnesium. The best way to prevent or avoid major complications is to identify the high-risk patient, or to diagnose earlier.

Meningitis and Riga-Fede disease: an unusual condition.

Riga-Fede disease (RFD) is a benign inflammatory disorder characterised by the appearance of a traumatic ulceration of the oral mucosa. Early detection of RFD and its adequate management are very important. The authors present a an unusual case of RFD with concomitant Staphylococcus aureus meningitis. A 36-day-old female infant was referred to the emergency room of the Hospital of the University of Siena for a 4-day history of high fever. Clinical evaluation revealed the presence of lingual ulceration caused by natal tooth. Few hours later, clinical manifestations were overshadowed by neurological symptoms. The cerebrospinal fluid examination showed the presence of Staphylococcus aureus. The wound healing after extraction of the tooth and the antibiotic therapy have been important for the resolution of this case. A conservative approach is preferable for natal teeth, but in this case the extraction was suggested since a more radical treatment was more likely to avoid major complications.

Natural history of acute and chronic hepatitis C.

2012-08-01

Hepatitis C virus (HCV) infection remains a major global health burden. Hepatitis C causes significant liver-related morbidity and mortality due to hepatic decompensation and development of hepatocellular carcinoma. In addition, extra-hepatic manifestations of hepatitis C are frequent. There is a very large interindividual variability in the natural history of both acute and chronic hepatitis C which can be explained in part by a combination of various host, viral and environmental factors. Successful antiviral treatment can prevent short- and long-term complications of HCV infection in many patients. Still, the relative contribution of distinct risk factors for disease progression in different phases of HCV infection needs to be better defined. Personalized treatment approaches for HCV infection should consider individual risk profiles to avoid both under- and over-treatment - which will remain important also in upcoming era of interferon-free treatment of hepatitis C.

Lee, Moses; Guyton, Gregory P; Zahoor, Talal; Schon, Lew C

2016-01-01

As a standard open approach, the lateral oblique incision has been widely used for calcaneal displacement osteotomy. However, just as with other orthopedic procedures that use an open approach, complications, including wound healing problems and neurovascular injury in the heel, have been reported. To help avoid these limitations, a percutaneous technique using a Shannon burr for calcaneal displacement osteotomy was introduced. However, relying on a free-hand technique without direct visualization at the osteotomy site has been a major obstacle for this technique. To address this problem, we developed a technical tip using a reference Kirschner wire. A reference Kirschner wire technique provides a reliable and accurate guide for minimally invasive calcaneal displacement osteotomy. Also, the technique should be easy to learn for surgeons new to the procedure. Copyright © 2016 American College of Foot and Ankle Surgeons. Published by Elsevier Inc. All rights reserved.

INTRODUCTION: Parastomal hernia is a common complication of stoma construction. Although the majority of patients are asymptomatic, about 10% require surgical correction. AIMS: We describe a new surgical approach for the repair of parastomal hernias, which avoids both the need for laparotomy and stoma mobilization. PATIENTS AND METHODS: Nine patients (4 female) with parastomal hernia underwent surgical repair. Median age was 55 years (range 38-73 years). There were 8 para-ileostomy herniae and one paracolostomy hernia. A lateral incision was made approximately 10 cm from the stoma, and carried down to the rectus sheath. The dissection was carried medially towards the stoma, and around the defect in the abdominal musculature. The hernia sac was excised when possible and the fascial defect closed with non-absorbable, monofilament suture. A polyprolene mesh was placed round the stoma by making a slit in the mesh. The skin was closed with subcuticular monofilament absorbable suture. RESULTS: All patients returned to normal diet on the first postoperative day, and were discharged from hospital within 72 h. There were no wound infections, and no recurrences after a median follow up of 6 months (range 3-12 months). DISCUSSION: The technique we describe is simple and avoids the need of laparotomy. The mucocutaneous junction of the stoma is not disturbed, reducing the risk of contamination of the mesh, stenosis or retraction of the stoma. Grooving of the stoma and difficulty in fitting appliances is avoided because the wound is not placed near the mucocutaneous junction. This approach may be superior to other mesh repairs for parastomal hernia. Images Figure 1 Figure 2 PMID:11432142

Diagnosis and Management of Nasopharyngeal Stenosis.

PubMed

Berent, Allyson C

2016-07-01

Choanal atresia is rare in small animal veterinary medicine, and most cases are misdiagnosed and are actually a nasopharyngeal stenosis (NPS), which is frustrating to treat because of the high recurrence rates encountered after surgical intervention. Minimally invasive treatment options like balloon dilation (BD), metallic stent placement (MS), or covered metallic stent (CMS) placement have been met with success but are associated with various complications that must be considered. The most common complication with BD alone is stenosis recurrence. The most common complications encountered with MS placement is tissue in-growth, chronic infections and the development of an oronasal fistula. The most common complications with a CMS is chronic infections and the development of an oronasal fistula, but stricture recurrence is avoided. Copyright © 2016 Elsevier Inc. All rights reserved.

A 34-year-old man presenting with a left inguinal mass was diagnosed as having idiopathic multiple aneurysmal disease and pseudoaneurysm of a left superficial femoral artery. A stent-graft was successfully deployed percutaneously at the left superficial femoral artery pseudoaneurysm. Less invasive treatment should be used to avoid vascular complications in patients with idiopathic multiple aneurysmal disease, especially in those who have a progressive course or a history of prior complications after surgical repair.

Background Birth preparedness and complication readiness (BPCR) is a strategy that helps women to consider all available maternal health care services during pregnancy and prepare for potential complications. Federal Ministry of Health in Ethiopia has taken steps to roll out the strategy at community level. Yet, women in rural communities still do not make use of available services to avoid complications in connection to pregnancy and delivery. Objective This study aims to assess the current BPCR practice and determine associated factors among rural women of reproductive age in Abeshige district, Guraghe zone, SNNPR, Ethiopia. Methods A community-based cross-sectional study was carried out from February to March 2015. A total of 454 women were randomly selected and interviewed using pretested structured questionnaires, while opinion leaders, health extension workers, and selected women in the community were engaged in in-depth interviews and focus group discussions, using checklists prepared to guide the interviews. Data from different sources were analyzed, triangulated, and interpreted to respond to the objectives. Results Thirty-seven percent of the respondents were found to have prepared for birth and its complications. BPCR was higher among women who lived within a 1-hour walk from a health center (adjusted odds ratio [AOR] =3.51, 95% confidence interval [CI]: 1.78, 36.79) and who were aware of the danger signs of pregnancy (AOR =1.72, 95% CI: 1.78, 2.94) and postpartum complications (AOR =2.32, 95% CI: 1.32, 4.21). A major source of information was found to be health extension workers and one-to-five women networks (AOR =2.81, 95% CI: 1.34, 6.21) and (AOR =2.52, 95% CI: 1.17, 5.54), respectively. Qualitative finding revealed that lack of transportation and concern over cost of services are key barriers to BPCR. Conclusion BPCR in Abeshige was found to be relatively low, calling for more interventions beyond mere awareness. Availing transportation services and ensuring services free of charge would help in improving BPCR in the study area. PMID:28053557

The anterior choroidal artery (AChoA) is a rare location for intracranial aneurysms. The treatment of these aneurysms may be challenging due to the risk of occlusion of such a small and eloquent artery as the AChoA. We aimed to evaluate the risk factors for complications in AChoA aneurysm treatment. We retrospectively analyzed 47 consecutive AChoA aneurysms in 40 patients treated in our institution from 1999 and 2014 by endovascular means (87%) or surgical clipping (13%). Minor (transient or minor neurological deficits) and major complications (severe permanent neurological deficits or death) were systematically recorded. The influence of patient age, sex, aneurysm size, neck size, shape, dome-to-neck ratio and treatment technique on the occurrence of procedure-related complications was evaluated. Of the patients 11 experienced procedure-related complications (5 major, 6 minor). Aneurysms with multilobed shape were significantly associated with a higher procedure-related complication rate. There was a tendency for higher major procedure-related complication rate in small volume aneurysms. We did not find any association between the other factors analyzed and occurrence of procedure-related complications. Treatment of AChoA aneurysms has an acceptable complication risk. We did not find any significant differences between surgical and endovascular treatment in terms of procedure-related complication rates. Multilobed aneurysms were significantly associated with a higher procedure-related complication rate.

Incidental finding of carcinoid tumor on Meckel’s diverticulum: case report and literature review, should prophylactic resection be recommended?

PubMed Central

2014-01-01

Meckel’s diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is caused by incomplete obliteration of the vitelline duct during intrauterine life. MD affects less than 2% of the population. In most cases, MD is asymptomatic and the estimated average complication risk of MD carriers, which is inversely proportional to age, ranges between 2% and 4%. The most common MD-related complications are gastrointestinal bleeding, intestinal obstruction and acute phlogosis. Excision is mandatory in the case of symptomatic diverticula regardless of age, while surgical treatment for asymptomatic diverticula remains controversial. According to the majority of studies, the incidental finding of MD in children is an indication for surgical resection, while the management of adults is not yet unanimous. In this case report, we describe the prophylactic resection of an incidentally detected MD, which led to the removal of an occult mucosal carcinoid tumor. In literature, the association of MD and carcinoid tumor is reported as a rare finding. Even though the strategy for adult patients of an incidental finding of MD during surgery performed for other reasons divides the experts, we recommend prophylactic excision in order to avoid any further risk.

The prevalence rate of transsexualism varies from 1 to 50,000, to 1 to 100,000. Although it remains an infrequent affliction, transsexualism generates usually major suffering and may be responsible of many complications like suicide, self-mutilations, affective disorders and social disabilities. Since the first descriptions of Esquirol in the nineteenth, the medical community has always been questioned on medical, legal, social or ethical aspects of transsexualism. The aetiology of the trouble is still unknown. In the absence of biological marker, the syndrome of transsexualism can be defined only with clinical criteria. The main differential diagnosis are sexual ambiguities and psychotic disorders. For the specialists, satisfying the patients demand of a surgical and social reassignment still remains the only way to improve their clinical condition and avoid the onset of many dramatic complications. Without any treatment, the evolution of the trouble is chronic, without remission. Longitudinal studies of transsexual patients with a five year follow-up demonstrated subjective improvement in two thirds of the patients and don't find either higher rates of suicides nor psychotic decompensations after surgery and hormonotherapy. Clinical and neuropsychological studies of sexually differentiated cognitive abilities of transsexual patients, before and after hormonotherapy, could allow us in improving the understanding of sexual differences of the brain.

Background: Fractures shaft femur is a major cause of morbidity and mortality in patients with lower extremity injuries. Aims: The aim of this study was to evaluate the efficacy of intramedullary Kirschner wires for the treatment of femoral shaft fracture in children. Subjects and Methods: This prospective study was conducted in the Department of Orthopaedic surgery in M. M. Medical College from June 2005 to June 2010. Sixty eight children with a mean age of 7.7 years (range, 2-14 years) were recruited from Emergency and out patient department having closed fracture of femoral shaft. All patients were operated under general anesthesia. All patients were followed for twelve months. Results: Out of sixty eight patients, sixty four patients underwent union in 42 to 70 days with a mean of 56 days. Touch down weight bearing was started on 2nd post-operative day. Complications found in four patients who had insignificant delayed union which were united next three weeks. Intramedullary Kirschner-wires were removed after an average of five months without any complications. The results were excellent in 94.1% (64/68) and good in 5.8% (4/68). Conclusion: This technique is simple, quick to perform, safe and reliable and avoids prolonged hospitalization with good results and is economical. PMID:23919189

Wandering spleen is a rare condition in children that is often caused by loss or weakening of the splenic ligaments. Its clinical presentation is variable; 64% of children with wandering spleen have splenic torsion as a complication. To provide up-to-date information on the diagnosis, clinical management and diagnostic imaging approaches for wandering spleen in infants and children and to underline the importance of color Doppler US and CT in providing important information for patient management. We report a series of three children with wandering spleen treated at our children's hospital over the last 6 years. All three underwent clinical evaluation, color Doppler US and CT and were surgically treated. We also reviewed 40 articles that included 55 patients younger than 18 years reported in the Medline database from 2002 to 2012. We correlated pathological data with imaging findings. Color Doppler US, the first imaging modality in investigating abdominal symptoms in children with suspected wandering spleen, yielded a diagnostic sensitivity of 54.9%, whereas CT achieved about 71.7%. Radiologic evaluation has a major role in confirming the diagnosis of a suspected wandering spleen and avoiding potentially life-threatening complications requiring immediate surgery.

A Novel Technique of a Transcorneal Suture to Manage an Iris Tuck into the Tube of a Glaucoma Drainage Device.

Glaucoma drainage devices create an alternative pathway of aqueous drainage from the anterior chamber by channelling aqueous out of the eye through a tube to a subconjunctival bleb or the suprachoroidal space. They may be associated with a number of potential complications including tube malpositioning. This malpositioning may have serious sequelae such as corneal endothelial damage, chronic iritis, tube iris touch, cataract formation, or tube occlusion. Occlusion of the mouth of the tube by the iris impedes aqueous drainage and results in the failure of intraocular pressure (IOP) control. Tube repositioning in cases of occlusion of the mouth of the tube by the iris often involves extensive and potentially complicated surgery requiring tube removal and reinsertion. We describe a new minimally invasive surgical technique for correcting posterior tube malposition resulting in tube occlusion by the iris. The iris had occluded the tube of a Baerveldt prototype glaucoma drainage devices and caused an intractable increased IOP. After our tube sling suture, the tube was free, and the IOP normalized. The procedure entailed no difficult dissection or major surgical intervention. The technique is illustrated by a surgical video. This novel technique is a simple method that relieved the occlusion successfully, and avoided the need to redissect the conjunctiva or shorten the tube.

Looking tired is enough for many 40-50-years-olds to ask a plastic surgeon for prophylactic rejuvenation. They want to achieve good and long lasting effects with harmonious features, small scars, and--as they are still very active in their professional and private lives--a quick recovery is very important to them. We have developed a modification of the short-scar face-lift with solid deep support. We call it the MIDI face-lift. MIDI stands for Minimal, Invasive, Deep, Intensive. Technical details are as follows. Two half Z-plasties were performed at each end of modest skin excision, supra-auriculary and retro-auriculary, to avoid even suture edges. By doing so we achieve very unobtrusive scarring. For solid SMAS tension we perform SMAS-plication, simple SMAS-flap, or tricuspidal SMAS-flap. This is an overview of 200 patients we treated over three years. By applying tumescent local anesthesia with adrenaline and ornipressin, and fibrin glue at the end of the procedure, we can the draining so that 96% of our patients were outpatients. Technical details will be discussed as well as complications, adjuvant and alternative procedures. The satisfaction of our patients was high (88%) and no major complications have occurred. Only three out of 200 patients had to undergo revisionary surgery.

ABSTRACT Background: Previous studies on the influence of different types of attachment on grief responses have yielded contradictory outcomes. Little research has been conducted to identify the psychological processes that moderate the relationship between attachment representations and patterns of grief in disaster-related grief. Objective: The present study examines the effects of different attachment types on the grief responses of parents bereaved by loss of a child in a ferry accident, along with the moderating role of coping strategies. Methods: Bereaved parents (n = 81) completed self-report questionnaires evaluating attachment, coping strategies, complicated grief, and shame/guilt. We performed correlational analyses to examine the associations among variables. We also conducted hierarchical regression analyses and simple slope analyses to examine the moderation effects of coping strategies. Results: Anxious attachment was associated with severe shame/guilt, and avoidant attachment correlated with complicated grief. Anxious attachment was positively associated with all types of coping strategies, and avoidant attachment was negatively related to problem- and emotion-focused coping. The use of problem-focused coping strategies was a significant moderator of the relationship between the avoidant attachment dimension and shame/guilt. Avoidant attachment had a significant effect on shame/guilt in groups with a high level of problem-focused coping. In contrast, none of the coping strategies significantly moderated the relationship between anxious attachment and grief response. Conclusions: The results suggest that people with highly avoidant attachment might be overwhelmed by shame and guilt when they try to use problem-focused coping strategies. This finding suggests that grief interventions should be organized with consideration of individual differences in attachment representations. PMID:29372009

Anterior clinoidectomy is a difficult yet essential technique in skull base surgery. Two main techniques (extradural and intradural) with multiple modifications have been proposed to increase efficiency and avoid complications. In this study, the authors sought to develop a hybrid technique based on localization of the optic strut (OS) to combine the advantages and avoid the disadvantages of both techniques. Ten cadaveric specimens were prepared for surgical simulation. After a standard pterional craniotomy, the anterior clinoid process (ACP) was resected in 2 steps. The segment anterior to the OS was resected extradurally, while the segment posterior to the OS was resected intradurally. The proposed technique was performed in 6 clinical cases to evaluate its safety and efficiency. Anterior clinoidectomy was successfully performed in all cadaveric specimens and all 6 patients by using the proposed technique. The extradural phase enabled early decompression of the optic nerve while avoiding the adjacent internal carotid artery. The OS was drilled intradurally under direct visualization of the adjacent neurovascular structures. The described landmarks were easily identifiable and applicable in the surgically treated patients. No operative complication was encountered. A proposed 2-step hybrid technique combines the advantages of the extradural and intradural techniques while avoiding their disadvantages. This technique allows reduced intradural drilling and subarachnoid bone dust deposition. Moreover, the most critical part of the clinoidectomy-that is, drilling of the OS and removal of the body of the ACP-is left for the intradural phase, when critical neurovascular structures can be directly viewed.

Multiple factors have been identified as predictors of complication after head and neck surgery. However, little is known about the exact role of different comorbid conditions in the development of postoperative complications. This question is especially interesting in the elderly population. The aim of this study was to investigate the association between comorbidity and types of postoperative complications with special attention to age differences. A retrospective analysis was performed of 1,201 major surgical interventions for head and neck malignancies in a tertiary referral center between 1995 and 2010. The Adult Comorbidity Evaluation 27 (ACE-27) index was used to analyze severity (mild, moderate, and severe comorbidity) and type (12 different organ systems) of comorbidity. The Clavien-Dindo index was used to evaluate grade and type of complications after treatment. In univariate analysis gender, comorbidity, stage, mandibulectomy, total laryngectomy, neck dissection, and length of surgery significantly predicted grade of complication. In a multivariate analysis, complication was predicted by age, stage, length of surgery, and various comorbidities. After specification of the complications, age was only a predictor of medical complications; tumor stage was a significant factor in surgical complications. Length of surgery was the only significant variable in all types of complications. Specific comorbidities are associated with specific complications; however, age itself seems not to be a contraindication for major head and neck surgery. With careful preoperative assessment and risk analysis, physicians can better individualize treatment recommendations.

Oesophagectomy is associated with significant morbidity and mortality. A simple score to define a patient's risk of developing major complications would be beneficial. Patients who underwent upper gastrointestinal resections with an oesophageal anastomosis between 2005 and 2010 were reviewed and formed the development dataset with resections performed in 2011 forming a prospective validation dataset. The association between post-operative C-reactive protein (CRP), white cell count (WCC) and albumin levels with anastomotic leak (AL) or major complication including death using the Clavien-Dindo (CD) classification were analysed by receiver operating characteristic curves. After multivariate analysis, from the development dataset, these factors were combined to create a novel score which was subsequently tested on the validation dataset. Two hundred fifty-eight patients were assessed to develop the score. Sixty-three patients (25%) developed a major complication, and there were seven (2.7%) in-patient deaths. Twenty-six (10%) patients were diagnosed with AL at median post-operative day 7 (range: 5-15). CRP (p = 0.002), WCC (p < 0.0001) and albumin (p = 0.001) were predictors of AL. Combining these markers improved prediction of AL (NUn score > 10: sensitivity 95%, specificity 49%, diagnostic accuracy 0.801 (95% confidence interval: 0.692-0.909, p < 0.0001)). The validation dataset confirmed these findings (NUn score > 10: sensitivity 100%, specificity 57%, diagnostic accuracy 0.879 (95% CI 0.763-0.994, p = 0.014)) and a major complication or death (NUn > 10: sensitivity 89%, specificity 63%, diagnostic accuracy 0.856 (95% CI 0.709-1, p = 0.001)). Blood-borne markers of the systemic inflammatory response are predictors of AL and major complications after oesophageal resection. When combined they may categorise a patient's risk of developing a serious complication with higher sensitivity and specificity.

To evaluate whether African American ethnicity is a risk factor for major respiratory complications following adenotonsillectomy (T&A). Retrospective cohort study. A Canadian tertiary care center. PATIENTS Children aged 0 to 18 years who underwent T&A at our institution from 2002 to 2006 with planned or unplanned postoperative admissions. We evaluated the association between ethnicity and our main outcome measure, major perioperative respiratory complications of T&A. Parental report of ethnicity was available for 23% of our cohort. At our institution, African American children undergo a routine preoperative sickle cell test (TestSC). Data on TestSC were included for all children. We established that having a TestSC was an accurate proxy for African American ethnicity (sensitivity, 96%; specificity, 93%; positive predictive value, 77%; negative predictive value, 99%). Seventy-four of 594 children experienced major respiratory complications (12.5%). Compared with children who did not have major respiratory complications, those who did had a TestSC (P = .01), were 2 years or younger (P < .001) and had lower weight-for-age z scores (P = .04), moderate to severe obstructive sleep apnea (P = .003), and comorbidities (P < .001). When controlling for these variables in a multivariate analysis, children of African American ethnicity (TestSC used as a proxy) were at higher risk of having major perioperative respiratory complications (adjusted odds ratio, 1.82 [95% CI 1.05-3.14]) (P = .003). Children of African American ethnicity (TestSC used as a proxy) are nearly twice as likely to experience major respiratory complications related to T&A. Ethnicity may be an additional independent risk factor for clinicians to consider when planning for T&A.

This study aims to evaluate the role of dynamic change in total bilirubin after portal vein embolization (PVE) in predicting major complications and 30-day mortality in patients with hilar cholangiocarcinoma (HCCA). Retrospective analysis of prospectively maintained data of 64 HCCA patients who underwent PVE before hepatectomy in our institution was used. Total bilirubin and other parameters were measured daily in peri-PVE period. The difference between them and the baseline value from days 0-5 to day -1 (∆D1) and days 5-14 to day -1 (∆D2) were calculated. The relationship between ∆D1 and ∆D2 of total bilirubin and major complications as well as 30-day mortality was analyzed. Out of 64 patients, 10 developed major complications (15.6 %) and 6 patients (9.3 %) had died within 30 days after surgery. The ∆D2 of total bilirubin after PVE was most significantly associated with major complications (P < 0.001) and 30-day mortality (P = 0.002). In addition, it was found to be an independent predictor of major complications after PVE (odds ratio (OR) = 1.050; 95 % CI 1.017-1.084). ASA >3 (OR = 12.048; 95 % CI 1.019-143.321), ∆D2 of total bilirubin (OR = 1.058; 95 % CI 1.007-1.112), and ∆D2 of prealbumin (OR = 0.975; 95 % CI 0.952-0.999) were associated with higher risk of 30-day mortality after PVE. Receiver operating characteristic curves showed that ∆D2 of total bilirubin were better predictors than ∆D1 for major complications (AUC (∆D2) 0.817; P = 0.002 vs. AUC (∆D1) 0.769; P = 0.007) and 30-day mortality (ACU(∆D2) 0.868; P = 0.003 vs. AUC(∆D1) 0.721;P = 0.076). Patients with increased total bilirubin in 5-14 days after PVE may indicate a higher risk of major complications and 30-day mortality if the major hepatectomy were performed.

Trans-catheter aortic valve implantation (TAVI) technology is rapidly evolving, with 412 procedures having been performed at our institution. Herein, we report a complete, prospective analysis of complications occurring during transvascular and trans-apical implantations with two different prostheses. Between June 2007 and June 2010, 412 patients (258 female, mean age 80.3±7.2 years, logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) 20.2%±13.0%) underwent TAVI through either a retrograde (n=252 transfemoral, n=28 transaxillary, and n=5 transaortic) or antegrade (n=127 trans-apical) approach at our institution. The trans-apical access was chosen only in cases where transvascular implantation was not possible. As many as 283 CoreValve and 129 Edwards Sapien prostheses were implanted. Thirty-day survival was 90.9%. Vascular complications occurred in 42 patients (10.2%). In four patients, lethal aortic root (n=3) or abdominal (n=1) aortic rupture occurred. Pericardial effusion developed in 53 patients (12.8%), which resulted in cardiac tamponade in 12 patients (2.9%). Twenty-three patients (5.6%) with valve malplacement were treated interventionally. In five patients (1.2%), emergency institution of cardiopulmonary bypass was required during the procedure for temporary support; all patients survived. Seventeen patients underwent re-intervention on the catheter valve (4.1%). With growing experience, complications with TAVI may be avoided by proper patient selection and skillful management. Other complications, when they occur, require a specific treatment algorithm to avoid delay in decision making. A considerable number of complications after TAVI require surgical treatment. Therefore, the ideal environment for TAVI procedures is a hybrid operating room, where a multidisciplinary team of surgeons, cardiologists, and anesthesiologists is best fitted to meet the current needs associated with TAVI technology. A reduction in complications was seen after 300 cases. This finding attests to the complexity of the procedure in addition to the experience required to reduce the incidence of complications.

Urinary tract infections (UTI) are the most common bacterial infections involving lower (cystitis, prostatitis) or upper (pyelonephritis, renal abscess, perinephric abscess) urinary tract. Differentiation of complicated and uncomplicated UTI is usually based on the presence of structural or functional urinary tract abnormalities, which can increase the risk of treatment failure and development of serious complications. Factors that increase the risk are foreign bodies, stones, obstruction, neurogenic bladder, kidney transplantation, immunosuppression, and pregnancy. Complicated UTI includes a spectrum of conditions that increase the risk of treatment failure, as well as of serious complications such as bacteremia and sepsis, perinephric abscess, renal impairment and emphysematous pyelonephritis. To avoid the potentially devastating outcomes, appropriate diagnostic procedures, antibiotic and surgical treatment, and appropriate follow-up are required. The incidence of complicated UTI will grow in the future due to general aging of the population, increasing incidence of diabetes, and ever growing number of immunocompromised and immunosuppressed patients. It is of key importance to recognize complicated UTI on time, and treat it wisely and aggressively to reduce duration of the disease and the risk of antibiotic resistance.

The effect of patient complications on physicians is not well understood. Our objective was to determine the impact of a surgeon's complication(s) on his/her emotional state and job performance. An anonymous survey was distributed to Midwest Surgical Society members and attending surgeons within the Grand Rapids, Michigan, community. There were 123 respondents (30.5% response rate). For the majority of participants, the first complication that had a significant emotional impact on them occurred during residency (51.2%). Most respondents reported this did not impair their professional functioning (77.2%). If a major complication was first experienced after residency, this had a greater likelihood of causing impairment (P < .05). Surgeons primarily dealt with the emotional impact by discussing it with a surgical partner (87.8%). Alcohol or other substance use increased in 6.5% of those surveyed. Most respondents (58.5%) felt it was difficult to handle the emotional effects of complications throughout their careers and this did not improve with experience. The majority of surgeons agreed that it was difficult to handle the emotional effects of complications throughout their careers. Efforts should be made to increase awareness of unrecognized emotional effects of patient complications and improve access to support systems for surgeons. Published by Mosby, Inc.

To describe the frequency and characteristics of complications of cochlear implant (CI) surgery at Edgardo Rebagliati Martins Hospital of social security in Lima-Peru between 2006 and 2015. A retrospective descriptive study of patients that underwent CI surgery between August 2006 and December 2015. Among the 107 patients with CIs, the overall proportion of complications was 18.7% (20/107): 14.9% (16/107) of minor complications, and 3.7% (4/107) of major complications. Regarding the time of onset of complications, 2.8% (3/107) were intraoperative and 14% (15/107) postoperative. CI surgery in Peru is a safe procedure with a low frequency of major complications, representing an effective therapy for patients with sensorineural hearing loss who do not respond to hearing aids.

A retrospective analysis was performed on 267 consecutive patients with Graves' disease (GD). The principal aim of this study was to evaluate the risk for recurrence and complications when changing the surgical method from subtotal (ST) to total thyroidectomy (TT). Information from 267 consecutive patients operated on for GD between 2000 and 2006 was collected at Uppsala University Hospital (143) and Falun County Hospital (128). There were 229 women and 38 men. Four patients were operated on twice. A total of 40 STs and 229 TTs were performed. Results were compared to those of a previous cohort from the same hospital, with a majority of STs (157/176) performed from 1980 to 1992. The risk for relapse of GD was reduced from 20 to 3.3 % after the shift from ST to TT. In terms of surgical complications, 2.2 % demonstrated permanent vocal cord paralysis and 4.5 % had persistent hypocalcemia, not significant when compared to the previous cohort. In spite of TT, there were four recurrences, all due to remnant thyroid tissue high up at the hyoid bone. Changing the surgical method did not affect postoperative progression of dysthyroid ophthalmopathy (DO, 7.0 vs. 7.5 %). There were no differences in outcome with respect to which hospital the patients had their operation. Change from ST to TT dramatically reduced the risk for recurrence of GD without increasing the rate of complications. TT is not more effective than ST in hampering progression of DO as has been advocated by some. Careful surgical dissection up to the hyoid bone is necessary to avoid recurrence.

Local repair of stoma prolapse: Case report of an in vivo application of linear stapler devices.

Monette, Margaret M; Harney, Rodney T; Morris, Melanie S; Chu, Daniel I

2016-11-01

One of the most common late complications following stoma construction is prolapse. Although the majority of prolapse can be managed conservatively, surgical revision is required with incarceration/strangulation and in certain cases laparotomy and/or stoma reversal are not appropriate. This report will inform surgeons on safe and effective approaches to revising prolapsed stomas using local techniques. A 58 year old female with an obstructing rectal cancer previously received a diverting transverse loop colostomy. On completion of neoadjuvant treatment, re-staging found new lung metastases. She was scheduled for further chemotherapy but incarcerated a prolapsed segment of her loop colostomy. As there was no plan to resect her primary rectal tumor at the time, a local revision was preferred. Linear staplers were applied to the prolapsed stoma in step-wise fashion to locally revise the incarcerated prolapse. Post-operative recovery was satisfactory with no complications or recurrence of prolapse. We detail in step-wise fashion a technique using linear stapler devices that can be used to locally revise prolapsed stoma segments and therefore avoid a laparotomy. The procedure is technically easy to perform with satisfactory post-operative outcomes. We additionally review all previous reports of local repairs and show the evolution of local prolapse repair to the currently reported technique. This report offers surgeons an alternative, efficient and effective option for addressing the complications of stoma prolapse. While future studies are needed to assess long-term outcomes, in the short-term, our report confirms the safety and effectiveness of this local technique.

Interventional radiology plays an important role in the management of deep pelvic abscesses. Percutaneous drainage is currently considered as the first-line alternative to surgery. A transgluteal computed tomography (CT)-guided approach allows to access to deep infected collections avoiding many anatomical obstacles (vessels, nerves, bowel, bladder). The objective of this study was to assess the safety and efficacy of a transgluteal approach by reviewing our clinical experience. We reviewed medical records of patients having undergone percutaneous CT-guided transgluteal drainage for deep pelvic abscesses. We focused on the duration of catheter drainage, the complications related to the procedures and the rate of complete resolution. Between 2005 and 2013, 39patients (27women and 12men; mean age: 52.5) underwent transgluteal approach CT-guided percutaneous drainage of pelvis abscesses in our department. The origins of abscesses were postoperative complications in 34patients (87.2%) and infectious intra-abdominal disease in 5patients (12.8%). The mean duration of drainage was 8.3days (range: 3-33). Laboratory cultures were positive in 35patients (89.7%) and Escherichia coli was present in 71.4% of the positive samples. No major complication was observed. Drainage was successful in 38patients (97.4%). A transpiriformis approach was more significantly associated with intra-procedural pain (P=0.003). Percutaneous CT-guided drainage with a transgluteal approach is a safe, well-tolerated and effective alternative to surgery for deep pelvic abscesses. This approach should be considered as the first-line intention for the treatment of deep pelvic abscesses. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

To evaluate retrospectively demographic, clinical and histopathological variables effective on mortality in patients who had undergone emergency surgery due to complicated colorectal cancer. A total of 39 patients underwent urgent surgical interventions due to complicated colorectal cancer at the Department of General Surgery, Dursun Odabaş Medical Center, between January 2010 and January 2015. Thirty three of these were included in the study. Six patients were excluded because complete medical records had been missing. Medical records of the 33 cases were retrospectively reviewed. There were 14 (42.5%) male and 19 (57.5%) female patients. Mean age was 60 years (range: 32- 83 years); 14 (42.5%) patients were less than 60 years old , while 19 (57.5%) were 60 years old or older. Operations were performed due to perforation (39.3%) and obstruction (60.6%) in 13 and 20 patients, respectively. Tumor localization was in the right and transverse colon in nine (21.2%) and in the left colon in 24 cases (72.7%). Eleven (33.3%) patients underwent resection and anastomosis, 13 (39.3%) resection and ostomy, and nine (27.2%) patients underwent ostomy alone without any resection. Postoperative mortality occurred in nine cases (27.2%). High mortality should be expected in females older than 60 years with a left sided colon tumor or with another synchronous tumor and in perforated tumors. Unnecessary major resections should be avoided and primary pathology should be in the focus of treatment in order to decrease the mortality and morbidity rates.

To report the diagnosis, treatment, and short-term outcome in dogs with suspected persistent right aortic arch (PRAA) undergoing thoracoscopy with concurrent esophagoscopy. Multi-institutional retrospective case series. Dogs with suspected PRAA (n=9). Medical records were reviewed from 2012 to 2016. Dogs undergoing thoracoscopy for PRAA at 3 referral hospitals were included. Signalment, clinical signs, diagnostic imaging, anesthesia protocol (including the use of one-lung ventilation), surgical approach, complications, and short-term outcome were recorded. Dogs underwent a left-sided intercostal thoracoscopic approach with concurrent intraoperative esophagoscopy. The ligamentum arteriosum (LA) and constricting fibers were divided using a vessel-sealing device using a 3 or 4 port thoracoscopy technique. Visualization and dissection of the LA was aided by transesophageal illumination by esophagoscopy. Thoracoscopy confirmed PRAA in 9 dogs, with an aberrant left subclavian artery (LS) identified in 5 dogs. Major complications occurred in 2 dogs: postoperative hemorrhage from the LS and esophageal perforation, which resulted in euthanasia. Median follow-up was 250 days (range, 56-1,595). Regurgitation resolved in 4 of 8 surviving dogs. One dog had recurrence of regurgitation 1,450 days postoperatively, esophageal compression by the LS was identified, and regurgitation resolved following LS transection. Esophagoscopy aided identification and dissection of the LA in all cases. Due to the potential for the LS to cause clinical esophageal constriction postoperatively, a recommendation for LS transection may be warranted. Vascular clips can also be considered as an alternative for vessel ligation to avoid complications associated with vessel-sealing device use. © Copyright 2016 by The American College of Veterinary Surgeons.

To identify preinjury coping profiles among adults with uncomplicated mild traumatic brain injury (mTBI) and complicated mTBI and to determine whether preinjury coping profiles contribute to the prediction of emotional functioning and quality of life (QOL) 3 months post-mTBI. One hundred eighty-seven persons with medically documented mTBI (uncomplicated mTBI, n = 89; complicated mTBI, n = 98) were recruited from the emergency center of a level I trauma center and followed in community 3 months post-mTBI. The Ways of Coping Questionnaire was administered within 2 weeks of injury. Cluster analysis was used to group participants on basis of their preinjury use of problem-focused and avoidant coping strategies. The Brief Symptom Inventory and the 36-item Short-Form Health Survey were administered 3 months postinjury. Cluster analysis distinguished 3 distinct preinjury coping profiles that were differentially associated with outcomes. Participants who used avoidant coping showed the worse emotional functioning and QOL outcomes, although this cluster also reported high usage of problem-focused strategies. Preinjury coping profiles explained a significant proportion of the variance in depression, anxiety, and mental health QOL at 3 months postinjury beyond that accounted for by demographic characteristics and mTBI severity. Cluster analysis holds practical value in illustrating the pattern of coping strategies used by person with uncomplicated and complicated mTBI. It appears worthwhile to address coping in future trials of interventions that are aimed at improving emotional functioning after mTBI.

Eighty-three cases of tracheopleuropulmonary injuries complicating enteral tube feeding are analyzed to identify the patterns of injury, and precipitating factors and ways to avoid them. Six new cases observed by the authors and 77 other cases cited in British literature between 1976 and 1987 are presented. In recent years, reports of this complication have been increasing, apparently in a geometrical progression: 8%, 18%, and 74% were reported between 1976 to 1979, 1980 to 1983, and 1984 to 1987, respectively. Sixty-one percent occurred in patients aged 60 years or older. Most of the patients (84%) were seriously ill, which compounded their complications. Seventy-four percent of all injuries were committed by house staff; the narrow bore tube with guide wire was used in 77% of cases. Less than reliable methods were used to confirm tube position in most instances. The presence of cuffed endotracheal tubes did not offer protection. The patients on mechanical ventilation tended to deteriorate if they developed a pneumothorax once the malpositioned tubes were removed. Of the cases reviewed for this report, 18 deaths occurred; 72% being directly related to the tube injuries. Lack of awareness, inadequate confirmatory methods, and insufficient supervision accounted for most of these preventable complications. Educating house/nursing staff in the use of the new tubes, closer supervision, and the application of equal measures of care and caution as employed in other invasive and potentially dangerous procedures are recommended to avoid disastrous outcome.

Background: Although the safety profile of hyaluronic acid fillers is favorable, adverse reactions can occur. Clinicians and patients can benefit from ongoing guidance on adverse reactions to hyaluronic acid fillers and their management. Methods: A multinational, multidisciplinary group of experts in cosmetic medicine convened the Global Aesthetics Consensus Group to review the properties and clinical uses of Hylacross and Vycross hyaluronic acid products and develop updated consensus recommendations for early and late complications associated with hyaluronic acid fillers. Results: The consensus panel provided specific recommendations focusing on early and late complications of hyaluronic acid fillers and their management. The impact of patient-, product-, and technique-related factors on such reactions was described. Most of these were noted to be mild and transient. Serious adverse events are rare. Early adverse reactions to hyaluronic acid fillers include vascular infarction and compromise; inflammatory reactions; injection-related events; and inappropriate placement of filler material. Among late reactions are nodules, granulomas, and skin discoloration. Most adverse events can be avoided with proper planning and technique. Detailed understanding of facial anatomy, proper patient and product selection, and appropriate technique can further reduce the risks. Should adverse reactions occur, the clinician must be prepared and have tools available for effective treatment. Conclusions: Adverse reactions with hyaluronic acid fillers are uncommon. Clinicians should take steps to further reduce the risk and be prepared to treat any complications that arise. PMID:27219265

To analyze the impact of infectious complications and microbiology in the postoperative period after major oncologic neck surgeries. A retrospective study conducted in an oncology center, including all the consecutive patients who developed infectious complications after major neck cancer surgery, from October 2012 to May 2016 (44 months). Among other data, we collected TNM stage, ASA score, body mass index, comorbidities and habits, pre and postoperative hemoglobin levels, albumin serum levels, pre-surgical treatments, length of inpatient stay, isolated microbiological agents and the recorded complications and mortality rate. In the studied period, 761 major neck surgeries were performed. Of these, 96 patients had complications (12.6%). Pharyngocutaneous fistula (PCF) was the most frequent complication (56%) and nosocomial pneumonia was the most common systemic complication (23%). Pseudomonas aeruginosa was the principal microorganism of the 26 species isolated (15%). 12 deaths were registered. Using multiple linear regression we concluded that flap/cutaneous necrosis and PCF were complications with statistical significance that prolonged inpatient stay. The same complications had significant relative risk for more than 30 days of hospitalization. The postoperative period is critical for the successful treatment of head and neck oncology patients. PCF and flap/cutaneous necrosis were the principal complications which worsened the outcomes during this critical period. The early recognition and treatment of these complications is crucial.

The association between tumor complexity and postoperative complications after partial nephrectomy (PN) has not been well characterized. We evaluated whether increasing renal tumor complexity, quantitated by nephrometry score (NS), is associated with increased complication rates following PN using the Clavien-Dindo classification system (CCS). We queried our prospectively maintained kidney cancer database for patients undergoing PN from 2007 to 2010 for whom NS was available. All patients underwent PN. Tumors were categorized into low- (NS: 4-6), moderate- (NS: 7-9), and high-complexity (NS: 10-12) lesions. Complication rates within 30 d were graded (CCS: I-5), stratified as minor (CCS: I or 2) or major (CCS: 3-5), and compared between groups. A total of 390 patients (mean age: 58.0 ± 11.9 yr; 66.9% male) undergoing PN (44.6% open, 55.4% robotic) for low- (28%), moderate- (55.6%), and high-complexity (16.4%) tumors (mean tumor size: 3.74 ± 2.4 cm; median: 3.2 cm) from 2007 to 2010 were identified. Tumor size, estimated blood loss, and ischemia time all significantly differed (p<0.0001) between groups; patient age, body mass index (BMI), and operative time were comparable. When stratified by CCS, minor and major complication rates for all patients were 26.7% and 11.5%, respectively. Minor complication rates were comparable (26.6 vs. 24.9 vs 32.8%; p=0.45), whereas major complication rates differed (6.4 vs. 11.1 vs. 21.9%; p=0.009) among tumor complexity groups. Controlling for age, gender, BMI, type of surgical approach, operative duration, and tumor complexity, prolonged operative time (odds ratio [OR]: 1.01; confidence interval [CI], 1.0-1.02) and high tumor complexity (OR: 5.4; CI, 1.2-24.2) were associated with the postoperative development of a major complication. Lack of external validation is a limitation of this study. Increasing tumor complexity is associated with the development of major complications after PN. This association should be validated externally and integrated into the decision-making process when counseling patients with complex renal tumors. Copyright © 2011 European Association of Urology.

Lodise, Thomas P; Fan, Weihong; Sulham, Katherine A

2016-01-01

Data indicate that acute bacterial skin and skin structure infection (ABSSSI) patients without major comorbidities can be managed effectively in the outpatient setting. Because most patients with ABSSSIs present to the emergency department, it is essential that clinicians identify candidates for outpatient treatment given the substantially higher costs associated with inpatient care. We examined the potential cost avoidance associated with shifting care from inpatient treatment with vancomycin to outpatient treatment with oritavancin for ABSSSI patients without major complications or comorbidities. A decision analytic, cost-minimization model was developed to compare costs of inpatient vancomycin versus outpatient oritavancin treatment of ABSSSI patients with few or no comorbidities (Charlson Comorbidity Index score ≤1) and no life-threatening conditions presenting to emergency department. Hospital discharge data from the Premier Research Database was used to determine the costs associated with inpatient vancomycin treatment. Mean costs for inpatient treatment with vancomycin ranged from $5973 to $9885, depending on Charlson Comorbidity Index score and presence of systemic symptoms. Switching an individual patient from inpatient vancomycin treatment to outpatient oritavancin treatment was estimated to save $1752.46 to $6475.87 per patient, depending on Charlson Comorbidity Index score, presence of systemic symptoms, and use of observation status. Assuming some patients may be admitted to the hospital after treatment with oritavancin, it is estimated that up to 38.12% of patients could be admitted while maintaining budget neutrality. This cost-minimization model indicates that use of oritavancin in the emergency department or observation setting is associated with substantial cost savings compared with inpatient treatment with vancomycin.

2017-01-01

Although the risk factors that contribute to postoperative complications are well recognized, prediction in the context of a particular patient is more difficult. We were interested in using a visual analog scale (VAS) to capture surgeons' prediction of the risk of a major complication and to examine whether this could be improved. The study was performed in 3 stages. In phase I, the surgeon assessed the risk of a major complication on a 100-mm VAS immediately before and after surgery. A quality control questionnaire was designed to check if the VAS was being scored as a linear scale. In phase II, a VAS with 6 subscales for different areas of clinical risk was introduced. In phase III, predictions were completed following the presentation of detailed feedback on the accuracy of prediction of complications. In total, 1295 predictions were made by 58 surgeons in 859 patients. Eight surgeons did not use a linear scale (6 logarithmic, 2 used 4 categories of risk). Surgeons made a meaningful prediction of major complications (preoperative median score 40 mm for complications v. 22 mm for no complication, P < 0.001; postoperative 46 mm v. 21 mm, P < 0.001). In phase I, the discrimination of prediction for preoperative (0.778), postoperative (0.810), and POSSUM (Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity) morbidity (0.750) prediction was similar. Although there was no improvement in prediction with a multidimensional VAS, there was a significant improvement in the discrimination of prediction after feedback (preoperative, 0.895; postoperative, 0.918). Awareness of different ways a VAS is scored is important when designing and interpreting studies. Clinical assessment of major complications by the surgeon was initially comparable to the prediction of the POSSUM morbidity score and improved significantly following the presentation of clinically relevant feedback. © The Author(s) 2016.

Minimally invasive surgical technique for tethered surgical drains

2017-01-01

A feared complication of temporary surgical drain placement is from the technical error of accidentally suturing the surgical drain into the wound. Postoperative discovery of a tethered drain can frequently necessitate return to the operating room if it cannot be successfully removed with nonoperative techniques. Formal wound exploration increases anesthesia and infection risk as well as cost and is best avoided if possible. We present a minimally invasive surgical technique that can avoid the morbidity associated with a full surgical wound exploration to remove a tethered drain when other nonoperative techniques fail.

Bowel perforation though rarely reported is a serious complication of induced abortion, which is often performed illegally by persons without any medical training in developing countries. A sudden increase in the number of patients in our centre in recent years prompted the authors to analyze this problem. The study was conducted to describe our own experiences in the surgical management of these patients. This was a retrospective study involving patients who were jointly managed by the surgical and gynecological teams at Bugando Medical Centre (BMC) for bowel perforation secondary to illegally induced abortion from January 2002 to December 2011. The statistical analysis was performed using SPSS version 17.0. A total of 68 patients (representing 4.2% of cases) were enrolled in the study. Their ages ranged from 14 to 45 years with a median age of 21 years. Majority of patients were, secondary school students/leavers (70.6%), unmarried (88.2%), nulliparous (80.9%), unemployed (82.4%) and most of them were dependent member of the family. Previous history of contraceptive use was reported in only 14.7% of cases. The majority of patients (79.4%) had procured the abortion in the 2nd trimester. Dilatation and curettage (82.4%) was the most common reported method used in procuring abortion. The interval from termination of pregnancy to presentation in hospital ranged from 1 to 14 days (median 6 days ). The ileum (51.5%) and sigmoid colon (22.1%) was the most common portions of the bowel affected. Resection and anastomosis with uterine repair was the most common (86.8%) surgical procedure performed. Complication and mortality rates were 47.1% and 10.3% respectively. According to multivariate logistic regression analysis, gestational age at termination of pregnancy, delayed presentation, delayed surgical treatment and presence of complications were significantly associated with mortality (P<0.001). The overall median length of hospital stay (LOS) was 18 days (1day to 128 days ). Patients who developed complications stayed longer in the hospital, and this was statistically significant (P=0.012). Bowel perforation following illegally induced abortion is still rampant in our environment and constitutes significantly to high maternal morbidity and mortality. Early recognition of the diagnosis, aggressive resuscitation and early institution of surgical management is of paramount importance if morbidity and mortality associated with bowel perforation are to be avoided.

The aim of this study is to evaluate the difference in perioperative complication rate in total hip, bipolar hemiarthroplasties and total knee arthroplasty in patients with Parkinson disease in trauma and elective surgery in our Musculoskeletal Center during a period of 10 years. Between 2006 and 2016, 45 bipolar hemiarthroplasties in trauma surgery, 15 total knee and 19 total hip arthroplasties in patients with Parkinson's disease were performed. We divided the patients in two groups. Group I included trauma cases (45) and group II elective surgery cases (34). Complications were documented and divided into local minor and major complications and general minor and major complications. Fisher's exact test was used for statistical evaluation. In both groups, there was one local major complication (p > 0.05): In group I, there was one case of loosening of a K-wire which was removed operatively. In group II, there was one severe intraarticular bleeding requiring puncture of the hematoma. In group I, there were 38 general complications; in group II, there were 17 general complications. There was no statistical difference in complication rate (p > 0.05). Total hip arthroplasty, bipolar hemiarthroplasties and knee arthroplasty in patients with Parkinson disease is possible in elective and trauma surgery. Complication rate is higher in comparison with patients not suffering from Parkinson disease, but there is no difference in complication rate in elective and trauma surgery. Nevertheless, early perioperative neurological consultation in patients with Parkinson disease is recommended to minimize complications and improve early outcomes after arthroplasty.

The vascular type of Ehlers-Danlos syndrome (EDS) is a rare genetic disease transmitted as an autosomal dominant trait. It is distinguished from other forms of EDS by its unstable acrogeric morphotype and by vascular, gastrointestinal, and obstetrical complications. Diagnosis is based on various clinical signs, noninvasive imaging, and on the identification of a mutation of the COL3A1 gene, which provides diagnostic certainty but has a sensitivity of only 61%. When two major diagnostic criteria are present, a genetic test should be proposed, performed and its result presented in a multidisciplinary group. The precautionary principle requires that preventive measures be implemented when the diagnosis is suspected. All artery puncture, surgery, and gastrointestinal and uterine endoscopy are contraindicated, permissible only in life-threatening emergencies. Straining against a closed glottis and all other situations or drugs likely to raise blood pressure must be avoided. Contraception must be discussed to avoid pregnancy during the diagnostic period. Arterial lesions suggestive of the disease include dissecting aneurysms of the internal carotid and iliac arteries and of the anterior visceral branches of the abdominal aorta, fusiform aneurysms of the splenic artery, and early onset nontraumatic direct carotid-cavernous fistulae. Early-onset varicose veins, spontaneous peritonitis or unusually important perineal lesions after giving birth should also attract the physician's attention. Psychological treatment and support of patients and their families is essential, to help them both to live with their disease and to deal with the information and screening issues. The prognosis of Ehlers-Danlos syndrome, vascular type, is grim but there is wide interindividual variability and life expectancy is best among patients receiving regular follow-up. Management by an experienced multidisciplinary team, implementation of drastic prevention measures and, depending on the results of the BBEST study, the possible prescription of beta-blockers should help to reduce the risk of complications and justify hope for a real improvement in prognosis in the near future.

This study reviewed the results of surgery for chronic pancreatitis. We also attempted to identify any factors that may influence outcome. A 10-year retrospective chart review was carried out on all patients undergoing surgery for the diagnosis of chronic pancreatitis. Twenty-three patients were identified. Alcohol was the most common etiology, but other causes were identified. All but two patients had abnormal ductal anatomy on endoscopic retrograde cholangiopancreatography. A total of 23 patients underwent six different operations. There were five complications and no perioperative deaths. Only one patient had to be readmitted for pancreatitis during follow-up. The majority of patients reported some improvement with their pain. Patients who continued to use alcohol had the worst results in regard to weight gain and pain control. The results of our study are consistent with the current literature in regard to morbidity and mortality. Surgical treatment had minimal effect on endocrine and exocrine function. Weight loss was avoided in the majority of patients. Addition of biliary bypass to the Puestow procedure did not increase morbidity. Poorest results were obtained in patients who continued to use alcohol. A basic algorithm for management of this disease process is given.

a comprehensive assessment of the water balance on the basis of daily, cumulative balance and 10% of the body weight gain and their role in the development of early complications after major abdominal surgery. A retrospective study of the perioperative period in 150 patients who underwent major abdomi- nal surgery was performed. The physical condition of the patients corresponded to ASA 3 class. The average age was 46 (38-62) years. The following stages ofresearch: an analysis of daily balance and cumulative balance in complicated and uncomplicated group and their role in the development of complications; the timing of development ofcomplications and possible relationship with fluid overload and the development of complications; changes in the level of albumin within 10 days of the postoperative period. The analysis of complications didn't show significant differences between complicated and uncomplicated groups according to the water balance during the surgery and by the end of the first day. When constructing the area under the ROC curve (A UROC) low resolution ofthe balance in intraoperative period and the first day and the balance on the second day to predict complications was shown. Significant diferences according to the cumulative balance was observed from the third day of the postoperative period Also with the third day of the postoperative period there is a good resolution for prediction ofpostoperative complications according to the cumulative balance with the cut-offpoint > of 50,7 ml/kg. the excessive infusion therapy is a predictor of adverse outcome in patients after major abdominal surgery. Therefore, after 3 days of postoperative period it is important to maintain mechanisms for the excretion of excess fluid or limitations of infusion therapy.

Atrial fibrillation (AF) ablation is increasingly common, but is associated with potential major complications. Technology, experience, and protocols have evolved significantly in recent times, and may have impacted procedural safety. We sought to compare AF ablation safety profiles, including complication rates and fluoroscopy times in a "modern" versus "historical" cohort. We evaluated consecutive patients undergoing AF ablation from a modern cohort (MC) from 2014 to 2015 and a historic cohort (HC) from 2009 to 2011 for complications. Major complications were categorized according to Heart Rhythm Society guidelines. We included 1,425 patients, 726 in the HC and 699 in the MC. The MC was older, had more OSA and less valvular AF. Fifty-two (3.5%) procedures suffered major complications across the cohorts, with significantly fewer in the MC (5.0% vs. 2.3%, P  =  0.007). The largest reductions were seen in vascular, hemorrhagic, ischemic stroke, and perforation/tamponade related complications. Periprocedural antiplatelets drugs (aHR 2.1 [95 CI 1.1-3.9], P  =  0.02) and force-sensing catheters (aHR 0.4 [95 CI 0.2-0.9], P  =  0.03) were independently related to major complication rates. Direct oral anticoagulants and uninterrupted anticoagulation were not associated with complications. There was a decrease in both fluoroscopy (-17.4 minutes [95 CI 19.2-15.6], P < 0.0001) and radiofrequency ablation times (-561 seconds [95CI -750 to -371], P < 0.0001). The safety profile of AF ablation has improved significantly in less than a decade. © 2018 Wiley Periodicals, Inc.

There is controversy in the literature about the choice of expectant medical treatment versus surgical treatment of hiatal hernias, depending on the presence or absence of symptoms. This study presents the results obtained by our group, considering disease duration and postoperative results. A total of 121 patients were included and divided by age, disease duration, type of hiatal hernia and postoperative outcome. In 32% of the patients younger than 70 years, symptom duration was longer than 11 years and 68% of those aged more than 71 years had long-term symptoms (p<.05). Type iv hernias (complex) and those with diameters measuring more than 16 cm were observed in the group with longer symptom duration. Complications were more frequent in the older age group, in those with longer symptom duration and in those with type iv complex hernias. There was no postoperative mortality and only one patient (0.8%) with a type iii hernia and severe oesophagitis required reoperation. We recommend that patients with hiatal hernia undergo surgery at diagnosis to avoid complications and risks. Older patients should not be excluded from surgical indication but should undergo a complete multidisciplinary evaluation to avoid complications and postoperative mortality. Copyright © 2012 AEC.

This study reports the findings of 120 traumatic pad injuries in pet and military dogs. Most dogs (68%) presented with a laceration to a thoracic limb footpad, and one-third of dogs were middle-aged castrated males. Metacarpal pads were most commonly injured. Short-term complications were noted in 27% of dogs. No long-term complications were identified. No disability from pad injury was present at the completion of healing. Concurrent injuries to adjacent structures were uncommon and did not affect outcome. Dogs with full-thickness pad lacerations were at greater risk for major short-term complications compared to dogs with partial-thickness pad lacerations (odds ratio, 7.27; P = .001). Military working dogs with full-thickness pad lacerations were at greater risk for major short-term complications than pet dogs with a similar injury. When major complications developed in dogs with full-thickness pad injuries, time to final healing was significantly longer (by a median of 12 days). The partial-thickness pad lesions healed uneventfully regardless of whether they were bandaged, surgically repaired, or left to heal by second intention. Suture repair and bandaging of full-thickness lesions could not be shown to either decrease the risk for complications or improve healing. Future work should focus on establishing standards for footpad treatment to reduce complications.

Extensive resection for hilar cholangiocarcinoma is the most effective treatment, but high morbidity and poor prognosis remain concerns. Previous data have shown marked differences in outcomes between comparable Eastern and Western centers. We compared the outcomes of the management for hilar cholangiocarcinoma at one Japanese and one British institution with comparable experience. Of 298 consecutive patients with hilar cholangiocarcinoma evaluated at Hirosaki University Hospital, Japan and St. James's University Hospital, Leeds, UK, 183 underwent radical resection. Clinicopathologic variables and postoperative outcomes were compared. Significant differences were not observed between the Hirosaki and Leeds cohorts in overall outcomes despite several differences in the patient characteristics. Although there was a difference in 90-day mortality (2.5% vs 13.6%, respectively), disease-specific 5-year survival rates were 32.8% and 31.9%, respectively (P = .767). Multivariate analysis identified trisectionectomy (odds ratio = 2.32; P = .010), combined pancreatoduodenectomy (odds ratio = 7.88; P = .010), and perioperative blood transfusion (odds ratio = 1.88; P = .045) were associated with postoperative major complications, while preoperative biliary drainage associated with postoperative major complications, while preoperative biliary drainage (risk ratio = 2.21; P = .018), perioperative blood transfusion (risk ratio = 1.58; P = .029), lymph node metastasis (risk ratio = 2.00; P = .002), moderate/poorly differentiated tumor (risk ratio = 1.72; P = .029), microvascular invasion (risk ratio = 1.63; P = .046), and R1 resection (risk ratio = 1.90; P = .005) were risk factors for poor survival. Disease-specific survival and prognostic factors were similar in both centers. Meticulous operative technique to avoid perioperative blood transfusion may improve long-term survival.

We assessed morbidity after 2 management strategies for arterial switch operation (ASO) in a single institution: first hours of life surgery and conventional approach. From September 2009 to September 2014, 346 consecutive patients who underwent ASO were enrolled. The study group included 92 patients who underwent ASO in the first 24 hours after birth (group I). The control group consisted of 254 patients who underwent ASO after 24 hours of life in the conventional way (group II). Three outcomes were analyzed: postoperative ventilation time (VT), post-extubation hospital length of stay (peLOS), and a composite morbidity index, defined as postoperative VT + peLOS + occurrence of selected major complications. Overall 30-day survival was 98% (2 [2%] group I vs 5 [2%] group II, P = 1.000). Fifty (13.3%) major complications were observed: 14 (15%) in group I and 36 (15%) in group II (P = 0.635). Although peLOS and morbidity index did not differ significantly between groups, postoperative VT (42 hours [24, 67] vs 27 hours [22, 47], P = 0.008) and total hospital stay were significantly longer in group II (18 days [10, 19] vs 14 days [12, 18]). A median volume of 80 mL (60-100 mL) of autologous umbilical cord blood was collected (80 mL, group 1 vs 60 mL, group II; P = 0.090). Homologous blood cell transfusion was avoided in 70 patients (78%) in group I and in 13 patients (6%) in group II (P < 0.001). Arterial switch operation during the initial 24 hours of life has similar outcomes in view of morbidity and mortality to the conventional approach. Copyright © 2017 Elsevier Inc.

To evaluate long-term clinical follow-up results of implanting subcutaneous port catheters (SPCs) on ipsilateral or contralateral with mastectomy side in patients with axillary lymph node dissection. A total of 73 patients composed of ipsilateral (34 catheters) and contralateral (39 catheters) groups, with SPCs were included. All patients had lumpectomy or modified radical mastectomy for breast cancer. Ipsilateral and contralateral groups had similar patient characteristics. Five late complications were seen in the ipsilateral group and 2 late complications in the contralateral group. No statistical significant difference was seen between two groups in regard to late complications. Four complications of the ipsilateral group were classified as major group C and 1 as major group D, while 1 complication of the contralateral group was classified as minor group B and 1 as major group C according to Society of Interventional Radiology (SIR) classification. No statistical significant difference was seen between complication rates of two groups in regard to SIR classification. SPC related complications do not differ in regard to ipsilateral or contralateral side selection on mastectomized patients with breast cancer and lymph node dissection. SPCs can be implanted on ipsilateral or contralateral sides of the operation in these patients.

Assessment of operative risk in geriatric patients undergoing emergency general surgery (EGS) is challenging. Frailty is an established measure for risk assessment in elective surgical cases. Emerging literature suggests the superiority of frailty measurements to chronological age in predicting outcomes. The aim of this study was to assess the outcomes in elderly patients undergoing EGS using an established Rockwood frailty index. We prospectively measured preadmission frailty in all geriatric (aged 65 years and older) patients undergoing EGS at our institution during a 2-year period. Frailty index (FI) was calculated using the modified 50-variable Rockwood Preadmission FI. Frail patients were defined by FI ≥ 0.25. Outcomes measures were in-hospital complications, development of major complications, and mortality. Multivariate regression analysis was performed. A total of 220 patients were enrolled, of which 82 (37%) were frail. Frailty index score did not correlate with age (R = 0.64; R(2) = 0.53; p = 0.1) and poorly correlated with American Society of Anesthesiologists score (R = 0.51; R(2) = 0.44; p = 0.045). Thirty-five percent (n = 77) of patients had postoperative complications and 19% (n = 42) had major complications. Frailty index was an independent predictor for development of in-hospital complications (odds ratio = 2.13; 95% CI, 1.09-4.16; p = 0.02) and major complications (odds ratio = 3.87; 95% CI, 1.69-8.84; p = 0.001). Age and American Society of Anesthesiologists score were not predictive of postoperative and major complications. Our FI model had 80% sensitivity, 72% specificity, and area under the curve of 0.75 in predicting complications in geriatric patients undergoing EGS. The overall mortality rate was 3.2% (n = 7) and all patients who died were frail. Frailty index independently predicts postoperative complications, major complications, and hospital length of stay in elderly patients undergoing emergency general surgery. Use of FI will provide insight into the hospital course of elderly patients, allowing for identification of patients in need and more efficient allocation of hospital resources.

2013-01-01

Ornithine transcarbamylase (OTC) deficiency is the most common inborn error in the metabolism of the urea cycle with an incidence of 1 in 14 000 live births. Pregnancy can trigger potentially fatal hyperammonemic crises. We report a successful pregnancy in a 29-year-old primiparous patient with a known diagnosis of OTC deficiency since infancy. Hyperammonemic complications were avoided due to careful multidisciplinary management which included a detailed antenatal, intrapartum and postnatal plan. Management principles include avoidance of triggers, a low-protein diet and medications which promote the removal of nitrogen by alternative pathways. Triggers include metabolic stress such as febrile illness, particularly gastroenteritis, fasting and any protein loading. In our case the patient, in addition to a restricted protein intake, was prescribed sodium benzoate 4 g four times a day, sodium phenylbutyrate 2 g four times a day and arginine 500 mg four times a day to aid excretion of ammonia and reduce flux through the urea cycle.

Spontaneous splenic rupture as a complication of infectious mononucleosis was diagnosed in a 19-year-old woman. Sonographic and MRI investigations revealed subcapsular hematoma of the spleen without overt rupture. The patient was managed conservatively. Somatostatin treatment was initiated in order to reduce splanchnic blood flow. Further clinical course of the patient was favourable. Seven days after the diagnosis of splenic rupture the patient was discharged from hospital. Non-operative management should be considered in patients with subcapsular splenic rupture to avoid complications of splenectomy (e.g. post-splenectomy sepsis).

Kawasaki disease is an acute febrile vasculitis of infancy and early childhood. It is uncommon in early infancy, because a significant proportion of these children do not meet the classical diagnostic criteria at this age. Infants younger than 6 months with persistent fever and some of the criteria of Kawasaki disease should always raise suspicion for Kawasaki disease early to avoid delayed diagnosis with severe cardiac complications. We present a 35-day-old infant with incomplete Kawasaki disease complicated with myocardial infarction during chicken pox.

Complications associated with prone surgical positioning during elective spine surgery have the potential to cause serious patient morbidity. Although many of these complications remain uncommon, the range of possible morbidities is wide and includes multiple organ systems. Perioperative visual loss (POVL) is a well described, but uncommon complication that may occur due to ischemia to the optic nerve, retina, or cerebral cortex. Closed-angle glaucoma and amaurosis have been reported as additional etiologies for vision loss following spinal surgery. Peripheral nerve injuries, such as those caused by prolonged traction to the brachial plexus, are more commonly encountered postoperative events. Myocutaneous complications including pressure ulcers and compartment syndrome may also occur after prone positioning, albeit rarely. Other uncommon positioning complications such as tongue swelling resulting in airway compromise, femoral artery ischemia, and avascular necrosis of the femoral head have also been reported. Many of these are well-understood and largely avoidable through thoughtful attention to detail. Other complications, such as POVL, remain incompletely understood and thus more difficult to predict or prevent. Here, the current literature on the complications of prone positioning for spine surgery is reviewed to increase awareness of the spectrum of potential complications and to inform spine surgeons of strategies to minimize the risk of prone patient morbidity.

Postoperative pulmonary complications are major causes of postoperative morbidity and mortality. Although several risk factors have been associated with postoperative pulmonary complications, they are not consistent between studies and, even in those studies in which these factors were identified, the predictive power is low. We hypothesized that postoperative pulmonary complications would correlate with the presence of intraoperative expiratory flow limitation. Candidates for this prospective observational study were patients undergoing general anesthesia for major abdominal surgery. Preoperative data collection included age, body mass index, American Society of Anesthesiologists class, smoking and dyspnea history, and room air PO2. Expiratory flow limitation was assessed intraoperatively using the positive end-expiratory pressure test. Postoperative data collection included the incidence of postoperative pulmonary complications. Of the 330 patients we enrolled, 31% exhibited expiratory flow limitation. On univariate analysis, patients with expiratory flow limitation were more likely to have postoperative pneumonia (5% vs 0%, P < .001) and acute respiratory failure (11% vs 1%, P < .001) and a longer length of hospital stay (7 vs 9 days, P < .01). Multivariate analysis identified that expiratory flow limitation increased the risk of developing postoperative pulmonary complications by >50% (risk ratio, 2.7; 95% confidence interval, 1.7-4.2). Age and Medical Research Council dyspnea score were also significant multivariate risk factors for pulmonary complications. Our results show that intraoperative expiratory flow limitation correlates with that of postoperative pulmonary complication after major abdominal surgery. Further work is needed to better understand the relevance of expiratory flow limitation on postoperative pulmonary outcomes.

Patients recovering from outpatient surgery are responsible for managing their pain, managing ambulation, and even implementing thromboembolism prophylaxis after discharge. Because of the importance of postoperative care to prevent complications, a model of care that helps a patient transition to independent self-care could provide optimal results. The authors investigated the safety and morbidity rate for patients who underwent body contouring procedures and overnight care at an attached, nurse-staffed guest suite facility. A retrospective review was conducted of 246 patients who underwent major body contouring and who stayed at least 1 night in the guest suite facility. Major complications included a return to the operating room within 48 hours, major wound infection, and unplanned hospitalization within 48 hours. Minor complications included any postsurgical effect necessitating unplanned physician intervention within the first 30 days. Univariate analyses correlating patient characteristics and complication rates were conducted, as well as comparison of complication rates among same procedures reported in the literature. The complication rate (major and minor complications) was 25.20%. Surgical site infection occurred in 8.13% of patients. The most common wound complication was erythema around the incision site (12.20%). Death, deep vein thrombosis, or pulmonary embolism did not occur. Comparison with relevant results reported in the literature indicated a significant reduction in the occurrence of postoperative venous thromboembolism. Patient education after surgery is essential to healing and adequate care. The guest suite model provides improved care and education for the patient and family postsurgery by addressing some of the known risk factors of plastic surgery. 4. © 2014 The American Society for Aesthetic Plastic Surgery, Inc.

Safety of Nonsteroidal Anti-inflammatory Drugs in Major Gastrointestinal Surgery: A Prospective, Multicenter Cohort Study.

PubMed

2017-01-01

Significant safety concerns remain surrounding the use of nonsteroidal anti-inflammatory drugs (NSAIDs) following gastrointestinal surgery, leading to wide variation in their use. This study aimed to determine the safety profile of NSAIDs after major gastrointestinal surgery. Consecutive patients undergoing elective or emergency abdominal surgery with a minimum one-night stay during a 3-month study period were eligible for inclusion. The administration of any NSAID within 3 days following surgery was the main independent variable. The primary outcome measure was the 30-day postoperative major complication rate, as defined by the Clavien-Dindo classification (Clavien-Dindo III-V). Propensity matching with multivariable logistic regression was used to produce odds ratios (OR) and 95 % confidence intervals. From 9264 patients, 23.9 % (n = 2212) received postoperative NSAIDs. The overall major complication rate was 11.5 % (n = 1067). Following propensity matching and adjustment, use of NSAIDs were not significantly associated with any increase in major complications (OR 0.90, 0.60-1.34, p = 0.560). Early use of postoperative NSAIDs was not associated with an increase in major complications following gastrointestinal surgery.

Analysis of a prospective multicenter database. To assess the ability of the recently created Adult Spinal Deformity (ASD) Frailty Index (ASD-FI) to predict odds of major complications and length of hospital stay for patients who had more severe preoperative deformity and underwent more invasive ASD surgery compared with patients in the database used to create the index. Accurate preoperative estimates of risk are necessary given the high complication rates currently associated with ASD surgery. Patients were enrolled by participating institutions in Europe, Asia, and North America from 2009 to 2011. ASD-FI scores were used to classify 267 patients as not frail (NF) (<0.3), frail (0.3-0. 5), or severely frail (SF) (>0.5). Multivariable logistic regression, adjusted for preoperative and surgical covariates such as operative time and blood loss, was performed to determine the relationship between ASD-FI category and incidence of major complications, overall incidence of complications, and length of hospital stay. The mean ASD-FI score was 0.3 (range, 0-0.7). We categorized 105 patients as NF, 103 as frail, and 59 as SF. The adjusted odds of developing a major complication were higher for SF patients (odds ratio = 4.4; 95% CI 2.0, 9.9) compared with NF patients. After adjusting for covariates, length of hospital stay for SF patients increased by 19% (95% CI 1.4%, 39%) compared with NF patients. The odds of developing a major complication or having increased length of stay were similar between frail and NF patients. Greater patient frailty, as measured by the ASD-FI, is associated with a longer hospital stay and greater risk of major complications among patients who have severe preoperative deformity and undergo invasive surgical procedures. 2.

Liability versus innovation: the legal case for regenerative medicine.

PubMed

Keren-Paz, Tsachi; El Haj, Alicia J

2014-10-01

Medical innovation occupies a position somewhere between standard practice and clinical research, but innovation is primarily intended to benefit an individual patient where standard treatment fails. Medical innovations in the area of regenerative medicine have the potential to completely transform medical practice, but rely upon some major revision to the nature of treatments beyond drug-based therapies. There is considerable investment in scientific and clinical research, but further attention could be paid to legal barriers to medical innovation imposed by the threat of medical malpractice. We survey in this article the legal framework for making determinations of medical malpractice in general, and highlight the issues specific to innovative treatments. In essence, liability could be imposed for failing to adequately inform the patient about the innovative nature of the suggested therapy or based on the fact that the risks outweighed the benefits. As for the latter, we examine whether liability is likely to be based merely on deviating from existing practice or on an examination on the merits of the treatments' risks and benefits. The facts that some risks are unforeseeable and some benefits are external to the patient complicate negligence determinations. The first fact relates to the problem of judging adverse events in hindsight; the second, to the obligation to make decisions based on the patient's best interest and avoid conflict of interests. In addition, we evaluate the relationship between the obligations to secure the patient's informed consent and to avoid clinical negligence. We identify the need for further research to examine the significance of the putative anti-innovation bias that current liability regimen has, and to examine whether a move to strict liability might avoid such bias, while being fair to patients who contribute for the advancement of medical knowledge by participating in innovative therapies.

[Conservative management of spontaneous splenic rupture as a complication of infectious mononucleosis: two case reports and literature review].

PubMed

Steiner-Linder, A; Ballmer, P E; Haller, A

2000-11-04

We report on conservative management of 2 patients with spontaneous splenic rupture associated with infectious mononucleosis. Both patients had an unremarkable hospital course and were discharged within 7 days of admission. Resolution of the haematoma was followed by ultrasound monitoring during the hospital stay. A literature review to 1999 shows that approximately 45 patients with serologically proven infectious mononucleosis have suffered spontaneous rupture of the spleen. Spontaneous splenic rupture is a rare but potentially fatal complication of infectious mononucleosis. Although splenectomy has been advocated in the past as the definitive therapy, we recommend that non-surgical management be considered in haemodynamically stable patients, to avoid the complications of splenectomy (e.g. post-splenectomy sepsis).

Posterior polar cataract: A review

PubMed Central

Kalantan, Hatem

2011-01-01

Posterior polar cataract is a rare form of congenital cataract. It is usually inherited as an autosomal dominant disease, yet it can be sporadic. Five genes have been attributed to the formation of this disease. It is highly associated with complications during surgery, such as posterior capsule rupture and nucleus drop. The reason for this high complication rate is the strong adherence of the opacity to the weak posterior capsule. Different surgical strategies were described for the handling of this challenging entity, most of which emphasized the need for gentle maneuvering in dealing with these cases. It has a unique clinical appearance that should not be missed in order to anticipate, avoid, and minimize the impact of the complications associated with it. PMID:23960967

We report a rare presentation of a ruptured pseudoaneurysm of the lateral plantar artery following tibiotalocalcaneal fusion with a retrograde nail at 1 month after the index surgery. Although case reports of pseudoaneurysms of larger arteries such as the anterior tibial artery and posterior tibial artery after ankle surgery (e.g., ankle arthroscopy, implant removal, Ilizarov application) have been reported, we report a rare complication of a pseudoaneurysm of the lateral plantar artery. We discuss the anatomic considerations of the lateral plantar artery in the foot and the entry point of the retrograde nail to avoid this unusual complication.

Technologies and devices for cosmetic procedures are developing with each passing day. However, increased and unauthorized use of such emerging technologies may also lead to increases in unexpected results and complications as well. Here, we report a case of facial cellulitis after a "beauty parlor" session of skin cleaning with jet stream peeling device in 19-year old female patient for the first time. Complications due to improper and unauthorized use of jet stream peeling devices may also cause doubts about the safety and impair the reputation of the technology as well. In order to avoid irreversible complications, local authorities should follow the technology and update the regulations where the dermatologists should take an active role.

WE-AB-202-01: Evaluating the Toxicity Reduction with CT-Ventilation Functional Avoidance Radiation Therapy

DOE Office of Scientific and Technical Information (OSTI.GOV)

Vinogradskiy, Y; Miyasaka, Y; Kadoya, N

Purpose: CT-ventilation is an exciting new imaging modality that uses 4DCTs to calculate lung ventilation. Studies have proposed to use 4DCT-ventilation imaging for functional avoidance radiotherapy which implies designing treatment plans to spare functional portions of the lung. Although retrospective studies have been performed to evaluate the dosimetric gains to functional lung; no work has been done to translate the dosimetric gains to an improvement in pulmonary toxicity. The purpose of our work was to evaluate the potential reduction in toxicity for 4DCT-ventilation based functional avoidance. Methods: 70 lung cancer patients with 4DCT imaging were used for the study. CT-ventilationmore » maps were calculated using the patient’s 4DCT, deformable image registrations, and a density-change-based algorithm. Radiation pneumonitis was graded using imaging and clinical information. Log-likelihood methods were used to fit a normal-tissue-complication-probability (NTCP) model predicting grade 2+ radiation pneumonitis as a function of doses (mean and V20) to functional lung (>15% ventilation). For 20 patients a functional plan was generated that reduced dose to functional lung while meeting RTOG 0617-based constraints. The NTCP model was applied to the functional plan to determine the reduction in toxicity with functional planning Results: The mean dose to functional lung was 16.8 and 17.7 Gy with the functional and clinical plans respectively. The corresponding grade 2+ pneumonitis probability was 26.9% with the clinically-used plan and 24.6% with the functional plan (8.5% reduction). The V20-based grade 2+ pneumonitis probability was 23.7% with the clinically-used plan and reduced to 19.6% with the functional plan (20.9% reduction). Conclusion: Our results revealed a reduction of 9–20% in complication probability with functional planning. To our knowledge this is the first study to apply complication probability to convert dosimetric results to toxicity improvement. The results presented in the current work provide seminal data for prospective clinical trials in functional avoidance. YV discloses funding from State of Colorado.

Using "Rebar" to Stabilize Rigid Chest Wall Reconstruction.

PubMed

Robinson, Lary A; Grubbs, Deanna M

2016-04-01

After major chest wall resection, reconstruction of the bony defect with a rigid prosthesis is mandatory to protect the underlying thoracic organs, and to prevent flail chest physiology. Although many methods have been described for chest wall reconstruction, a commonly used technique employs a composite Marlex (polypropylene) mesh with methyl-methacrylate cement sandwiched between two layers of mesh (MMS), which is tailored to the defect size and shape. In building construction, steel "rebar" is used to strengthen and reinforce masonry structures. To avoid the initial residual motion of the rigid prosthesis used to reconstruct very large defects, particularly the sternum, we devised a simple technique of adding one or more Steinmann steel pins as "rebar" to strengthen and immediately stabilize the prosthesis to the surrounding ribs and sternum. For the very large defects, particularly over the heart and great vessels, titanium mesh may also be readily added into the sandwich construction for increased strength and to prevent late prosthetic fractures. Short- and long-term results of this inexpensive modification of the MMS reconstruction technique are excellent. This modified MMS tailor-made prosthesis is only one-third the cost of the recently popular prosthetic titanium systems, takes much less operative time to create and implant, and avoids the well-described complications of late titanium bar fracture and erosion/infection as well as loosening of screws and/or titanium bars.

Many burns surgeons avoid excision and direct closure of acute burns owing to concerns over wound dehiscence, scarring and infection. There is no evidence in the literature to support this practice. We present outcomes of a prospective series of 100 patients who underwent excision and direct closure of 138 burns over a 2-year period, along with results from a survey sent to 33 senior burns surgeons to gauge attitudes towards direct closure in burns surgery. 47% of survey respondents never perform direct closure. Dehiscence was cited as the most common concern, followed by hypertrophic scarring (HTS). In our cohort, the superficial dehiscence rate was 12% and the HTS rate was 16%, with no scarring contractures. Patients with healing time greater than 14 days were more likely to develop HTS (p=0.008), as were those with wound dehiscence (p=0.014). Patients undergoing part-grafting in addition to direct closure took significantly longer to heal than those undergoing direct closure alone (p=0.0002), with the donor site or graft delaying healing in the majority. Excision and direct closure of acute burn wounds avoids donor site morbidity and has an acceptable complication rate. It is a safe and effective treatment for full thickness burns in selected cases.

2010-12-01

The high rates of morbidity and mortality after subarachnoid hemorrhage due to spontaneous rupture of an intracranial aneurysm are mainly the result of neurologic complications. Sixty years after cerebral vasospasm was first described, this problem remains unsolved in spite of its highly adverse effect on prognosis after aneurysmatic rupture. Treatment is somewhat empirical, given that uncertainties remain in our understanding of the pathophysiology of this vascular complication, which involves structural and biochemical changes in the endothelium and smooth muscle of vessels. Vasospasm that is refractory to treatment leads to cerebral infarction. Prophylaxis, early diagnosis, and adequate treatment of neurologic complications are key elements in the management of vasospasm if neurologic damage, lengthy hospital stays, and increased use of health care resources are to be avoided. New approaches to early treatment of cerebral lesions and cortical ischemia in cases of subarachnoid hemorrhage due to aneurysm rupture should lead to more effective, specific management.

Multidetector CT of expected findings and complications after contemporary inguinal hernia repair surgery

PubMed Central

Tonolini, Massimo

2016-01-01

Inguinal hernia repair (IHR) with prosthetic mesh implantation is the most common procedure in general surgery, and may be performed using either an open or laparoscopic approach. This paper provides an overview of contemporary tension-free IHR techniques and materials, and illustrates the expected postoperative imaging findings and iatrogenic injuries. Emphasis is placed on multidetector CT, which represents the ideal modality to comprehensively visualize the operated groin region and deeper intra-abdominal structures. CT consistently depicts seroma, mesh infections, hemorrhages, bowel complications and urinary bladder injuries, and thus generally provides a consistent basis for therapeutic choice. Since radiologists are increasingly requested to investigate suspected iatrogenic complications, this paper aims to provide an increased familiarity with early CT studies after IHR, including complications and normal postoperative appearances such as focal pseudolesions, in order to avoid misinterpretation and inappropriate management.

Laser peripheral iridotomy is the procedure of choice for the treatment of angle-closure glaucoma caused by relative or absolute pupillary block. Nd: YAG laser iridotomy has been reported to have several complications such as Iris bleeding, hyphema, transient IOP elevation, intraocular inflammation, choroidal, retinal detachment and vitreous hemorrhage. We report a case of a 74 year old lady on anticoagulant treatment who developed pupillary block and angle closure glaucoma after cataract surgery and anterior chamber intraocular lens (ACIOL) insertion complicated with intraoperative bleeding. The patient was treated with Nd: YAG laser iridotomy , however, the ACIOL was inadvertently fractured after a single shot of laser and it had to be replaced. Although the incidence is rare. Ophthalmologists and Opticians should be aware that an ACIOL may be fractured even after a single Nd:YAG laser shot and avoid to perform it close to the ACIOL. Pretreatment counseling should include this rare complication.

Uterine cervical varix is rare, and its clinical course is poorly understood. Therefore, we present a case report of cervical varix complicating placenta previa before describing our findings in the context of an electronic database search of relevant reports. In the case report, we describe the clinical course and imaging results of a 35-year-old woman who was diagnosed with cervical varix complicated by placenta previa. Investigation by magnetic resonance imaging, serial ultrasonography, and speculum confirmed the diagnosis, and a healthy baby was successfully delivered at 36 weeks of gestation by cesarean section. An electronic search identified nine previous cases of cervical varix complicated by placenta previa in the literature. Clinicians should be aware of cervical varices when managing placenta previa to avoid iatrogenic rupture or misdiagnosis of placenta accreta by magnetic resonance imaging. © 2016 Japan Society of Obstetrics and Gynecology.

Esophagojejunal anastomosis fistula is the main complication after a total gastrectomy. To avoid a complex procedure on friable inflamed perianastomotic tissues, a coated self-expandable stent is mounted at the site of the anastomotic leak. A complication of stenting procedure is that it might lead to distal esophageal stenosis. However, another frequently encountered complication of stenting is stent migration, which is treated nonsurgically. When the migrated stent creates life threatening complications, surgical removal is indicated. We present a case of a 67-year-old male patient who was treated at our facility for a gastric adenocarcinoma which developed, postoperatively, an esophagojejunostomy fistula, a distal esophageal stenosis, and a metallic coated self-expandable stent migration. To our knowledge, this is the first reported case of an esophagojejunostomy fistula combined with a distal esophageal stenosis as well as with a metallic coated self-expandable stent migration.

Analysis of the medical, organizational, and administrative issues surrounding the care of a dignitary in an intensive care unit. On January 4, 2006, Ariel Sharon, the Israeli Prime Minister was emergently admitted to the Hadassah-Hebrew University Medical Center in Jerusalem owing to a severe intracranial hemorrhage. Immediately following his admission, he underwent an extensive neurosurgical procedure to control the bleeding. Thereafter, he required intensive care for 5 months and underwent additional procedures. This admission presented organizational and administrative challenges. The major challenge was to provide the Prime Minister with the best medical care while avoiding the "very important person syndrome" and simultaneously continuing routine hospital activities. To coordinate his complicated medical management, a consultation forum was established composed of all the physicians directly involved in Mr. Sharon's care. Additionally, a senior intensivist was chosen to coordinate the medical care and, along with a physician from the hospital administration, assist with administrative issues. Among the issues that the coordinating team addressed, with the help of many other hospital services, included patient confidentiality vs. public information, security of the patient's medical chart (including laboratory data and imaging), and coordination with security personnel. The acute care of a major governmental official requires the medical staff to address many administrative issues, while providing the "very important person" patient with appropriate intensive medical care. This article presents a strategy for addressing these issues.

Patients of all ages present to the Emergency Department (ED) with fractures that require immobilization using a cast. Various casting materials are used, all with advantages and disadvantages and there are considerable risks associated with fracture management using cast immobilization. The frequency and severity of complications from fiberglass or hybrid casts applied in the emergency setting has not previously been studied. The aim of this audit was to describe all the complications that occurred within 30 days in patients who had a fiberglass cast applied for immobilization of uncomplicated, non-angulated fractures of the foot, ankle or forearm. A retrospective care record audit was conducted that included 430 patients. The most common complications found were skin complications and cast related problems. No severe complications (e.g. compartment syndrome, venous thromboembolism or infection) were found. Fiberglass casts did not cause severe complications in this group of patients with uncomplicated fractures of the extremities. However, 25% of the patients experienced some form of complication. Interventions are needed that minimize the frequency of complications. As with all healthcare interventions, it is crucial that staff applying casts and providing follow-up care are competent. If casts are applied correctly and the patient is well informed and concordant, complications can be avoided. Copyright © 2018 Elsevier Ltd. All rights reserved.

Severe preeclampsia is a disorder of pregnancy characterized by high blood pressure and significant proteinuria after 20 weeks gestation. Severe preeclampsia and eclampsia have considerable adverse impacts on maternal, fetal, and neonatal health especially in low-resource countries. Hypertensive disorders of pregnancy are the third leading cause of maternal deaths in Sub-Saharan Africa. Significant avoidable maternal and neonatal morbidity and mortality may result. This study aimed 1) to determine the incidence of severe preeclampsia/eclampsia in a low-resource setting; 2) to determine the maternal complications of severe preeclampsia/eclampsia in a low-resource setting; 3) to determine the perinatal outcomes of severe preeclampsia/eclampsia in a low-resource setting. This was a retrospective descriptive cohort study carried out at Mpilo Central Hospital, a tertiary teaching referral government hospital in a low-resource setting in Bulawayo, Zimbabwe. Data were obtained from the birth registers in labor ward, intensive care unit, and neonatal intensive care unit of patients who had a diagnosis of severe preeclampsia or eclampsia for the period January 1, 2016, to December 31, 2016. The case notes were retrieved and the demographic, clinical, and outcome data were gathered. There were 9,086 deliveries at the institution during the period January 1, 2016, to December 31, 2016. There were 121 cases of severe preeclampsia/eclampsia. The incidence of severe preeclampsia/eclampsia was 1.3% at Mpilo Central Hospital. The most common major complication was HELLP syndrome (9.1%). Maternal mortality was 1.7%. There were 127 babies born with six sets of twins, 49.6% of the babies were lost through stillbirths and early neonatal deaths. The incidence of severe preeclampsia/eclampsia at Mpilo Central Hospital was 1.3%. The most common maternal complication was hemolysis elevated liver enzymes low platelet syndrome. Maternal mortality was 1.7% due to acute renal failure. Nearly half (49.6%) of the babies born were lost to stillbirths and early neonatal deaths.

Evolution of Inbreeding Avoidance and Inbreeding Preference through Mate Choice among Interacting Relatives.

PubMed

Duthie, A Bradley; Reid, Jane M

2016-12-01

While extensive population genetic theory predicts conditions favoring evolution of self-fertilization versus outcrossing, there is no analogous theory that predicts conditions favoring evolution of inbreeding avoidance or inbreeding preference enacted through mate choice given obligate biparental reproduction. Multiple interacting processes complicate the dynamics of alleles underlying such inbreeding strategies, including sexual conflict, distributions of kinship, genetic drift, purging of mutation load, direct costs, and restricted kin discrimination. We incorporated these processes into an individual-based model to predict conditions where selection should increase or decrease frequencies of alleles causing inbreeding avoidance or inbreeding preference when females or males controlled mating. Selection for inbreeding avoidance occurred given strong inbreeding depression when either sex chose mates, while selection for inbreeding preference occurred given very weak inbreeding depression when females chose but never occurred when males chose. Selection for both strategies was constrained by direct costs and restricted kin discrimination. Purging was negligible, but allele frequencies were strongly affected by drift in small populations, while selection for inbreeding avoidance was weak in larger populations because inbreeding risk decreased. Therefore, while selection sometimes favored alleles underlying inbreeding avoidance or preference, evolution of such strategies may be much more restricted and stochastic than is commonly presumed.

Type 2 Diabetes Mellitus is a serious health problem. In the year 2030 it will affect 366 million people around the world. Evaluate the effectiveness of a mixed intervention and reducing the amount and seriousness of acute complications in diabetics from our Health Area. Protocols of action as well as information documents were produced. Diabetes Unit coordinated educational activities in the different support levels of the Area VII of Murcia. Information talks were provided for the people in charge of the Diabetes Unit in every Care Center and Service of the Health Area. Personalized training was provided for patients treated in the different Care levels. The study comprised three stages. Information leaflets were spread and talks offered to the patient regarding in house handling of hypo and hyper glycemia. A reduction of 39% of the emergencies due to acute non complicated diabetes was achieved, as well as a reduction of 47.6% of hospital admissions. There was a reduction of 67.8% of the amount of total hospital stays for the group of patients under 35 years who were admitted into the hospital due to type 1 or 2 diabetes mellitus that didn't show any complications (GRD295). There was a reduction of more than thirty percent in the emergencies due to acute decompensations in the disease and a significant reduction in the avoidable hospital stays in the young adult, thus improving the patients' life quality and reducing the social cost of the diabetic patient.

Heart block and cardiac embolization of fractured inferior vena cava filter.

2016-01-01

A 66-year-old man underwent a placement of an inferior vena cava filter before a gastric surgery 9 years prior, presented to the emergency room with a complete atrioventricular block. Chest x-ray and transthoracic echocardiogram showed struts migrating to right ventricle with tricuspid regurgitation. Cardiothoracic surgery was consulted and declined an open surgical intervention due to the location of the embolized fragments and the patient's overall condition. It was also felt that the fragments had migrated chronically and were adhered to the cardiac structures. The patient underwent a dual-chamber permanent pacemaker implantation. Post-implant fluoroscopy showed no displacement of the inferior vena cava filter struts due to the pacemaker leads indicating that the filter fracture had likely been a chronic process. This case highlights a rare combination of complications related to inferior vena cava filter fractures and the importance of assessing for such fractures in chronic placements. Inferior vena cava filter placement for a duration greater than 1 month can be associated with filter fractures and strut migration which may lead to, although rare, serious or fatal complications such as complete atrioventricular conduction system disruption and valvular damage including significant tricuspid regurgitation. Assessing for inferior vena cava filter fractures in chronic filter placement is important to avoid such complications. When possible, retrieval of the filter should be considered in all patients outside the acute setting in order to avoid filter-related complications. Filter retrieval rates remain low even when a retrievable filter is in place and the patient no longer has a contraindication to anticoagulation.

Oronasal communication occurs after total maxillectomy for advanced sinonasal cancers. This results in feeding, breathing and cosmetic impairment. Various methods have been described to close off the palatal defect from the oral cavity to improve the function of speech and deglutition. The object of this article is to describe our experience of preservation of palatal mucoperiosteum for oronasal separation. Retrospective review of clinical and operative records of 31 total maxillectomy patients where oronasal separation was achieved by the conventional technique of applying a maxillary obturator. The postoperative complications arising from the use of maxillary obturator for oronasal communication after total maxillectomy in these 31 patients were analysed. To avoid the complications encountered in these 31 patients we preserved and used the ipsilateral palatal mucoperiosteum for oronasal separation. This new technique was applied in 12 patients. The results are presented and compared. A total of 43 patients underwent total maxillectomy for advanced sinonasal tumors. In 31 patients the conventional maxillary obturator was used for oronasal separation. Among these patients, 30 had crustation of the maxillary cavity, nasal regurgitation and cheek skin retraction in 15 each, trismus in eight, infection of skin graft donor site in seven, cheek movement during respiration in five and ill-fitting prosthesis in three. In 12 patients palatal mucoperiosteum was preserved and used for oronasal separation. The complications encountered in oronasal separation by palatal prosthesis were avoided in the modified procedure. We found that oronasal separation by preservation of palatal mucoperiosteum following total maxillectomy allowed excellent palatal function, prompt rehabilitation and minimal complications without compromising the prognosis.

Disease burden evaluation of fall-related events in the elderly due to hypoglycemia and other diabetic complications: a clinical review.

PubMed

Malabu, Usman H; Vangaveti, Venkat N; Kennedy, Richard Lee

2014-01-01

A hypoglycemia-induced fall is common in older persons with diabetes. The etiology of falls in this population is usually multifactorial, and includes microvascular and macrovascular complications and age-related comorbidities, with hypoglycemia being one of the major precipitating causes. In this review, we systematically searched the literature that was available up to March 31, 2014 from MEDLINE/PubMed, Embase, and Google Scholar using the following terms: hypoglycemia; insulin; diabetic complications; and falls in elderly. Hypoglycemia, defined as blood glucose <4.0 mmol/L (70 mg/dL) requiring external assistance, occurs in one-third of elderly diabetics on glucose-lowering therapies. It represents a major barrier to the treatment of diabetes, particularly in the elderly population. Patients who experience hypoglycemia are at a high risk for adverse outcomes, including falls leading to bone fracture, seizures, cognitive dysfunction, and prolonged hospital stays. An increase in mortality has been observed in patients who experience any one of these events. Paradoxically, rational insulin therapy, dosed according to a patient's clinical status and the results of home blood glucose monitoring, so as to achieve and maintain recommended glycemic goals, can be an effective method for the prevention of hypoglycemia and falls in the elderly. Contingencies, such as clinician-directed hypoglycemia treatment protocols that guide the immediate treatment of hypoglycemia, help to limit both the duration and severity of the event. Older diabetic patients with or without underlying renal insufficiency or other severe illnesses represent groups that are at high risk for hypoglycemia-induced falls and, therefore, require lower insulin dosages. In this review, the risk factors of falls associated with hypoglycemia in elderly diabetics were highlighted and management plans were suggested. A target hemoglobin A1c level between 7% and 8% seems to be more appropriate for this population. In addition, the first-choice drugs should have good safety profiles and have the lowest probability of causing hypoglycemia - such as metformin (in the absence of significant renal impairment) and incretin enhancers - while other therapies that may cause more frequent hypoglycemia should be avoided.

Satellite conjunction assessment is perhaps the fastest-growing area in space situational awareness and protection, with military, civil, and commercial satellite owner operators embracing more and more sophisticated processes to avoid the avoidable namely collisions between high-value space assets and orbital debris. NASA and CNES have collaborated to offer an introductory short course on all the major aspects of the conjunction assessment problem. This half-day course will cover satellite conjunction dynamics and theory, JSpOC conjunction data products, major risk assessment parameters and plots, conjunction remediation decision support, and present and future challenges. This briefing represents the NASA portion of the course.

To systematically review studies concerning imaging-guided minimally-invasive breast cancer treatments. An online database search was performed for English-language articles evaluating percutaneous breast cancer ablation. Pooled data and 95% confidence intervals (CIs) were calculated. Technical success, technique efficacy, minor and major complications were analysed, including ablation technique subgroup analysis and effect of tumour size on outcome. Forty-five studies were analysed, including 1,156 patients and 1,168 lesions. Radiofrequency (n=577; 50%), microwaves (n=78; 7%), laser (n=227; 19%), cryoablation (n=156; 13%) and high-intensity focused ultrasound (HIFU, n=129; 11%) were used. Pooled technical success was 96% (95%CI 94-97%) [laser=98% (95-99%); HIFU=96% (90-98%); radiofrequency=96% (93-97%); cryoablation=95% (90-98%); microwave=93% (81-98%)]. Pooled technique efficacy was 75% (67-81%) [radiofrequency=82% (74-88); cryoablation=75% (51-90); laser=59% (35-79); HIFU=49% (26-74)]. Major complications pooled rate was 6% (4-8). Minor complications pooled rate was 8% (5-13%). Differences between techniques were not significant for technical success (p=0.449), major complications (p=0.181) or minor complications (p=0.762), but significant for technique efficacy (p=0.009). Tumour size did not impact on variables (p>0.142). Imaging-guided percutaneous ablation techniques of breast cancer have a high rate of technical success, while technique efficacy remains suboptimal. Complication rates are relatively low. • Imaging-guided ablation techniques for breast cancer are 96% technically successful. • Overall technique efficacy rate is 75% but largely inhomogeneous among studies. • Overall major and minor complication rates are low (6-8%).

To perform a literature review of the spectrum of complications associated with UAE relative to surgery and compare the risk of reintervention as well as minor, major, and overall complications. Literature review was conducted in PubMed, MEDLINE, Cochrane, and CINAHL databases, and meta-analysis was performed. In randomized clinical trials, common complications were discharge and fever (4.00 %), bilateral uterine artery embolization (UAE) failure (4.00 %), and postembolization syndrome (2.86 %). Two trials showed a significantly decreased risk in major complications with UAE, with odds ratios (ORs) of 0.07143 (0.009426-0.5413) and 0.5196 (0.279-0.9678). None of the trials showed a significant differencemore » in OR for minor complications of UAE. None of the trials showed a significant difference in risk for overall complications of UAE. Three trials showed a significantly increased risk for reintervention with UAE with ORs of 10.45 (2.654-41.14), 2.679 (1.289-5.564), and 9.096 (1.269-65.18). In 76 nonrandomized studies, common complications were amenorrhea (4.26 %), pain (3.59 %), and discharge and fever (3.37 %). In 41 case studies, common complications were discharge and fever (n = 22 cases), repeat UAE (n = 6 cases), and fibroid expulsion (n = 5 cases). Overall, UAE has a significantly lower rate of major complications relative to surgery, but it comes at the cost of increased risk of reintervention in the future. Educating patients about the rate and types of complications of UAE versus surgery, as well as the potential for reintervention, should help the patient and clinician come to a reasoned decision.« less

More than 7000 male circumcisions are performed in Scandinavia every year. Circumcision is regulated in different ways in Sweden and Denmark and Norway. This study reviewed and described factors associated with complications of circumcision in infant boys in Scandinavia over the last two decades and discussed how these complications could be avoided. Data on significant complications following circumcision on boys under the age of one in Scandinavia over the last 20 years were collected. Information was retrieved from testimonies of circumcisers, witnesses, medical records and verdicts. A systematic review was performed of fatal cases in the literature. We found that 32 cases had been reported to the health authorities in the three countries, and we identified a total of 74 complications in these cases. These included four boys with severe bleeding and circulatory shock, which ended in the death of one boy. Other less serious complications may have occurred in other boys, but not been reported. Complications following male circumcision in Scandinavia were relatively rare, but serious complications did occur. Based on the analyses of the severe cases, we argue that circumcision should only be performed at hospitals with 24-hour emergency departments. ©2016 Foundation Acta Paediatrica.

2017-01-01

Lumbar fusion is a procedure broadly performed for degenerative diseases of spines, but it is not without significant morbidities. Surgical Apgar Score (SAS), based on intraoperative blood loss, blood pressure, and heart rate, was developed for prognostic prediction in general and vascular operations. We aimed to examine whether the application of SAS in patients undergoing fusion procedures for degeneration of lumbar spines predicts in-hospital major complications. One hundred and ninety-nine patients that underwent lumbar fusion operation for spine degeneration were enrolled in this retrospective study. Based on whether major complications were present (N=16) or not (N=183), the patients were subdivided. We identified the intergroup differences in SAS and clinical parameters. The incidence of in-hospital major complications was 8%. The duration of hospital stay for the morbid patents was significantly prolonged (p=0.04). In the analysis of multivariable logistic regression, SAS was an independent predicting factor of the complications after lumbar fusion for degenerative spine diseases [p=0.001; odds ratio (95% confidence interval)=0.35 (0.19-0.64)]. Lower scores were accompanied with higher rates of major complications, and the area was 0.872 under the receiver operating characteristic curve. SAS is an independent predicting factor of major complications in patients after fusion surgery for degenerative diseases of lumbar spines, and provides good risk discrimination. Since the scoring system is relatively simple, objective, and practical, we suggest that SAS be included as an indicator in the guidance for level of care after lumbar fusion surgery.

We aimed to conduct a meta-analysis of serious adverse events (macro- and microvascular events, falls and fractures, death) associated with hypoglycaemia in older patients. We searched MEDLINE and EMBASE spanning a ten-year period up to March 2015 (with automated PubMed updates to October 2015). We selected observational studies reporting on hypoglycaemia and associated serious adverse events, and conducted a meta-analysis. We assessed study validity based on ascertainment of hypoglycaemia, adverse events and adjustment for confounders. We included 17 studies involving 1.86 million participants. Meta-analysis of eight studies demonstrated that hypoglycemic episodes were associated with macrovascular complications, odds ratio (OR) 1.83 (95% confidence interval [CI] 1.64, 2.05), and microvascular complications in two studies OR 1.77 (95% CI 1.49, 2.10). Meta-analysis of four studies demonstrated an association between hypoglycaemia and falls or fractures, OR 1.89 (95% CI 1.54, 2.32) and 1.92 (95% CI 1.56, 2.38) respectively. Hypoglycaemia was associated with increased likelihood of death in a meta-analysis of eight studies, OR 2.04 (95% Confidence Interval 1.68, 2.47). Our meta-analysis raises major concerns about a range of serious adverse events associated with hypoglycaemia. Clinicians should prioritize individualized therapy and closer monitoring strategies to avoid hypoglycaemia in susceptible older patients. Copyright © 2016 Elsevier Inc. All rights reserved.

Radiologic Percutaneous Gastrostomy in Nondistended Stomach: A Modified Approach

IntroductionGastrostomy tube placement for patients requiring long-term nutritional support may be performed using different techniques including endoscopic, surgical, and percutaneous radiologically guided methods. Radiologically inserted gastrostomy (RIG), typically performed when percutaneous endoscopic gastrostomy is not possible, requires proper gastric distension that is achieved by insufflating air through a nasogastric tube. We describe a simple technique to prevent air escape from the stomach during gastrostomy tube placement. To the best of our knowledge, this technique has not yet been described in the literature.Materials and MethodsFour patients with unsuccessful percutaneous endoscopic gastrostomy were referred for fluoroscopic-guided gastrostomy. One patient had a pyriformmore » sinus tumor and three had an ischemic stroke causing dysphagia. Gastric distention was not achieved in the patients due to air escaping into the bowel during the standard RIG procedure. A modified approach using a balloon catheter inflated in the pylorus to avoid air passing into the duodenum permitted successful RIG.ResultsThe modified RIG procedure was successfully carried out in all cases without complications.DiscussionInadequate air distension of the stomach is an unusual event that causes a failure of gastrostomy tube placement and an increased risk of both major and minor complications. The use of a balloon catheter inflated in the first part of the duodenum prevents the air passage into the bowel allowing the correct positioning of the gastrostomy.« less

Thirty-day unplanned hospital readmission in ovarian cancer patients undergoing primary or interval cytoreductive surgery: systematic literature review.

PubMed

Clark, Rachel M; Rice, Laurel W; Del Carmen, Marcela G

2018-06-18

Thirty-day readmission rate has been proposed as metric of quality and remains an ongoing clinical concern in the primary treatment of patients with advanced-stage ovarian epithelial ovarian cancer. We conducted a review of the literature to identify rates, risk factors, and predictors for 30-day readmission in this population. A 10-year period MEDLINE (PubMed) search of English literature studies published between January 01, 2008-January 01, 2018 was performed to identify appropriate studies for review. Thirty -day readmission rates for ovarian cancer patients undergoing primary treatment ranged from 2.5-19.3%. Neoadjuvant chemotherapy and interval cytoreductive surgery (NACT-ICS) surgery was associated with lower readmission rates, when compared to primary debulking surgery (PDS). The most frequently reported adverse events resulting in readmission include inpatient management of ileus/small bowel obstruction, wound-related complications, and thromboembolic events. Readmission predictors included the presence of other medical comorbidities, re-operation, and major complications occurring after initial hospital discharge. Some studies reported lower rates of readmission and survival in patients treated by NACT-ICS. Policies and programs should be designed to measure short- and long-term outcomes in this patient population to avoid bias in assigning patients to NACT-ICS to maintain low 30-day readmission rates.

A rare complication following tracheotomy is common carotid artery (CCA) pseudoaneurysm. Treatment modalities for CCA pseudoaneurysm include surgical repair and single-artery balloon-covered stent graft technique. We describe successful treatment of tracheotomy-related CCA pseudoaneurysm with the "kissing balloon" expandable stent graft technique. We successfully implemented the kissing balloon expandable stent graft technique for treatment of a large, narrow-necked, bilobed CCA pseudoaneurysm that arose owing to a tracheotomy complication. The pseudoaneurysm was detected while performing a diagnostic angiogram of the aortic arch and surrounding vessels. The stent was deployed while the 2 balloons were introduced in a kissing manner such that they faced one another to avoid occlusion of either branch of the innominate artery coming into contact; 1 balloon was inflated at the origin of the right subclavian artery, and the other was inflated at the right innominate artery simultaneously. The pseudoaneurysm was successfully contained; normal blood flow was restored in the CCA. The balloons were deflated and withdrawn. The patient remained neurologically intact after the procedure. The kissing balloon technique is a safe and effective alternative to surgical repair, as it prevents morbidities associated with the surgical procedure. Also, this technique decreases the risk of major side-branch occlusion associated with the single-artery balloon-covered stent graft technique. Copyright © 2018 Elsevier Inc. All rights reserved.

Lead is a toxic element of the environment which leads to major complications once it enters the blood stream, affecting multiple organs and systems of the body. We present the case of a 16-year-old girl, diagnosed with lead poisoning after occupational exposure due to the fact that the girl was actively involved in the family's pottery business.History revealed that the girl participated in the process of pottery, her father was also diagnosed with lead poisoning 2 years before. The patient's personal history underlined that approximately 1 year ago she presented with severe abdominal pain, being diagnosed with acute appendicitis and she underwent appendectomy, but the pain persisted, thus due to family history of lead poisoning, the suspicion of saturnine colic rose, and she was diagnosed with lead poisoning. The main symptoms and signs were severe abdominal pain, vomiting, and arterial hypertension. The clinical evolution was favorable under symptomatic treatment and chelation therapy. Lead toxicity is a life-threatening condition because of its severe acute and chronic complications. In children, there is no safe blood lead level, prevention methods are, therefore, very important in order to avoid toxic multiorganic effects of this metal. Even though the diagnosis of lead poisoning remains difficult in children, it must also be taken into consideration by the clinician facing a child with gastrointestinal or neurological involvement.

2007-12-01

This study investigated the effects of nutritional support on postoperative complications, in relation with demographic and nutritional factors, intraoperative factors, type and routes of nutritional regimens. A series of 1410 subjects underwent major abdominal surgery for gastrointestinal cancer and received various types of nutritional support: standard intravenous fluids (SIF; n=149), total parenteral nutrition (TPN; n=368), enteral nutrition (EN; n=393), and immune-enhancing enteral nutrition (IEEN; n=500). Postoperative complications, considered as major (if lethal or requiring re-operation, or transfer to intensive care unit), or otherwise minor, were recorded. Major and minor complications occurred in 101 (7.2%) and 446 (31.6%) patients, respectively. Factors correlated with postoperative complications at multivariate analysis were pancreatic surgery, (p<0.001), advanced age (p=0.002), weight loss (p=0.019), low serum albumin (p=0.019) and nutritional support (p=0.001). Nutritional support reduced morbidity versus SIF with an increasing protective effect of TPN, EN, and IEEN. This effect remained valid regardless the severity of risk factors identified at the multivariate analysis and it was more evident by considering infectious complications only. Pancreatic surgery, advanced age, weight loss and low serum albumin are independent risk factors for the onset of postoperative complications. Nutritional support, particularly IEEN, significantly reduced postoperative morbidity.

Extracranial-to-intracranial (EC-IC) bypass surgery may be necessary in patients with moyamoya disease and other ischemic conditions. However, there is a potential risk of wound-related complications in some cases. In this study, we report our approach to prevention of wound-related complications in EC-IC bypass, and technical consideration and pitfalls of surgery are discussed. This study included 89 patients with ischemic-onset moyamoya disease and atherosclerotic disease, who underwent 108 superficial temporal artery (STA)-to-middle cerebral artery bypass procedures. Our study emphasized 3 major features. First, 3-dimensional simulation imaging was used to confirm STA anatomy. Second, the STA was meticulously dissected on the epigaleal layer, and protected the galeal layer. Third, scalp skin ischemia was taken into consideration at each step until skin closure. There was no neurological morbidity or mortality in this series. There were 2 cases with major wound-related complications that needed plastic surgical intervention, and 4 cases with minor complications that were treated conservatively. In major complication cases, the scalp defect was treated with pedicle flap reconstruction. In EC-IC bypass surgery, interdisciplinary management involving neurosurgery, plastic surgery, and radiology should reduce wound-related complications, and achieve safe surgery.

Chlorpropamide was found to be an effective antidiuretic agent in vasopressin-sensitive diabetes insipidus. Full clinical use of this action is limited by the frequent occurrence of hypoglycemia on higher doses. This complication can be avoided, however, by restricting the dose and by employing combination therapy with hydrochlorothiazide. PMID:5563815

To describe our experience and current management approach for congenital nasal neuroglial heterotopia (NGH) and encephaloceles. Retrospective chart review at a tertiary pediatric hospital from 1970 to 2013. Thirty patients met inclusion criteria: 21 NGH and nine encephaloceles. Data including demographics, pathology, imaging modality, surgical approach, resection extent, outcomes, and complications were analyzed. Fourteen NGH patients (67%) presented with an internal nasal mass and nasal obstruction. Three patients (14%) presented with an external nasal mass and four (19%) had a mixed lesion. Median age at surgery was 0.51 years (interquartile range 1.32 years). Thirteen (62%) had an intranasal endoscopic approach. Median operative time was 1.6 hours (interquartile range 1.2 hours), and there were no major complications. Nine patients with encephalocele were identified: six (67%) presented with transethmoidal encephaloceles, two (22%) presented with nasoethmoidal encephaloceles, and one (11%) presented with a nasofrontal lesion. The median age at surgery was 1.25 years (interquartile range 1.4 years). All patients required a craniotomy for intracranial extension. Median operative time was 5 hours (interquartile range 1.9 hours), and eight patients (88%) had a total resection. Length of stay ranged from 3 to 14 days. Nasal neuroglial heterotopia and encephaloceles are very rare lesions that require multidisciplinary evaluation and management. At our institution, there has been a shift to magnetic resonance imaging alone for the evaluation of NGH to avoid radiation exposure. Endoscopic extracranial resection is feasible for most intranasal and mixed NGH without an increase in operative time, residual disease, or complications. 4.

Extended-criteria donors (ECDs) have an impact on early allograft dysfunction (EAD), biliary complications, relapse of hepatitis C virus (HCV), and survivals. Early allograft dysfunction was frequently seen in grafts with moderate and severe steatosis. Donors after cardiac death (DCD) have been associated with higher rates of graft failure and biliary complications compared to donors after brain death. Extended warm ischemia, reperfusion injury and endothelial activation trigger a cascade, leading to microvascular thrombosis, resulting in biliary necrosis, cholangitis, and graft failure. The risk of HCV recurrence increased by donor age, and associated with using moderately and severely steatotic grafts. With the administration of protease inhibitors sustained virological response was achieved in majority of the patients. Donor risk index and EC donor scores (DS) are reported to be useful, to assess the outcome. The 1-year survival rates were 87% and 40% respectively, for donors with a DS of 0 and 3. Graft survival was excellent up to a DS of 2, however a DS >2 should be avoided in higher-risk recipients. The 1, 3 and 5-year survival of DCD recipients was comparable to optimal donors. However ECDs had minor survival means of 85%, 78.6%, and 72.3%. The graft survival of split liver transplantation (SLT) was comparable to that of whole liver orthotopic liver transplantation. SLT was not regarded as an ECD factor in the MELD era any more. Full-right-full-left split liver transplantation has a significant advantage to extend the high quality donor pool. Hypothermic oxygenated machine perfusion can be applied clinically in DCD liver grafts. Feasibility and safety were confirmed. Reperfusion injury was also rare in machine perfused DCD livers.

2017-04-01

Necrotizing fasciitis (NF) is a rare, potentially fatal, infective complication that can occur after surgery. Diagnosis is still difficult and mainly based on clinical data. Only a prompt pharmacological and surgical therapy can avoid dramatic consequences. There are few reports regarding NF as a complication after aesthetic surgical procedures, and a systematic review still lacks. We have performed a systematic review of English literature on PubMed, covering a period of 30 years. Keywords used were "necrotising fasciitis" matched with "aesthetic surgery complications", "breast surgery", "mammoplasty", "blepharoplasty", "liposuction", "facelift", "rhinoplasty fasciitis", "arm lift", "thigh lift", "otoplasty" and "abdominoplasty fasciitis". No additional search and temporal limitation were set. Among 3782 papers concerning NF, only 18 were related to NF after an aesthetic surgical procedure. Liposuction was the most affected procedure, with buttocks and lower extremity the most involved anatomical regions. The majority of the infections were monomicrobial, promoted by Streptococcus pyogenes. In most cases, NF occurred within the third post-operative day with non-specific signs and symptoms. In 14 cases, a single or multiple surgical interventions were performed and survival was achieved in 11 patients. In case of infection after aesthetic surgery, we should always bear in mind NF. Clinical hallmarks still guide NF management. Because early signs and symptoms are usually non-specific, a strict clinical control is highly suggested. Once clinical suspicion is raised, prompt antibacterial therapy should be administered, followed by surgical debridement in case of ineffective response. This journal requires that authors assign a level of evidence to each article.

A versatile breast reduction technique: Conical plicated central U shaped (COPCUs) mammaplasty

PubMed Central

Copcu, Eray

2009-01-01

Background There have been numerous studies on reduction mammaplasty and its modifications in the literature. The multitude of modifications of reduction mammaplasty indicates that the ideal technique has yet to be found. There are four reasons for seeking the ideal technique. One reason is to preserve functional features of the breast: breastfeeding and arousal. Other reasons are to achieve the real geometric and aesthetic shape of the breast with the least scar and are to minimize complications of prior surgical techniques without causing an additional complication. Last reason is the limitation of the techniques described before. To these aims, we developed a new versatile reduction mammaplasty technique, which we called conical plicated central U shaped (COPCUs) mammaplasty. Methods We performed central plication to achieve a juvenile look in the superior pole of the breast and to prevent postoperative pseudoptosis and used central U shaped flap to achieve maximum NAC safety and to preserve lactation and nipple sensation. The central U flap was 6 cm in width and the superior conical plication was performed with 2/0 PDS. Preoperative and postoperative standard measures of the breast including the superior pole fullness were compared. Results Forty six patients were operated with the above mentioned technique. All of the patients were satisfied with functional and aesthetic results and none of them had major complications. There were no changes in the nipple innervation. Six patients becoming pregnant after surgery did not experience any problems with lactation. None of the patients required scar revision. Conclusion Our technique is a versatile, safe, reliable technique which creates the least scar, avoids previously described disadvantages, provides maximum preservation of functions, can be employed in all breasts regardless of their sizes.

To describe a new technique for transcatheter patent ductus arteriosus (PDA) closure in extremely preterm infants using commercially available technology. PDA in premature neonates continues to be a significant clinical problem contributing importantly to both morbidity and mortality. Surgical ligation and medical therapy both have their drawbacks. Hospital records and catheterization reports of all premature neonates (< 32 weeks gestation) who underwent transcatheter PDA closure between March 2013 and February 2014 were reviewed. Particular attention was paid to procedural details, complications, and short and mid-term outcomes. Six premature infants born at gestational ages ranging between 26 and 31 weeks (median, 26 weeks) underwent attempted transcatheter PDA closure using the Amplatzer Vascular Plug II (AVP II). Median age and weight was 21.5 days (16-80 days) and 1,180 g (870-2,240 g), respectively. Fluoroscopy and echocardiography were used to guide device. Contrast angiography was not used in any patient. Complete closure was achieved in all patients with no major procedural complications. Median fluoroscopy and procedural times were 9.4 (0-19.5) and 51.5 (33-87) min, respectively. All patients were alive at the time of this report. There were no instances of device migration, left pulmonary artery (LPA), or aortic coarctation. This preliminary study demonstrates that transcatheter PDA closure can be successfully performed in extremely preterm neonates using currently available technology with a high success rate and a low incidence of complications. This report also describes a novel transvenous approach using a combination of echocardiography and judicious use of fluoroscopy to avoid arterial access in this fragile patient population. © 2014 Wiley Periodicals, Inc. © 2014 Wiley Periodicals, Inc.

Comprehensive and standardized reporting of adverse events after robot-assisted radical cystectomy (RARC) and urinary diversion for bladder cancer is necessary to evaluate the magnitude of morbidity for this complex operation. To accurately identify and assess postoperative morbidity after RARC using a standardized reporting system. A total of 241 consecutive patients underwent RARC, extended pelvic lymph node dissection, and urinary diversion between 2003 and 2011. In all, 196 patients consented to a prospective database, and they are the subject of this report. Continent diversions were performed in 68% of cases. All complications within 90 d of surgery were defined and categorized by a five-grade and 10-domain modification of the Clavien system. Univariable and multivariable logistic regression analyses were used to identify predictors of complications. Grade 1-2 complications were categorized as minor, and grade 3-5 complications were categorized as major. All blood transfusions were recorded as grade ≥2. Eighty percent of patients (156 of 196 patients) experienced a complication of any grade ≤90 d after surgery. A total of 475 adverse events (113 major) were recorded, with 365 adverse events (77%) occurring ≤30 d after surgery. Sixty-eight patients (35%) experienced a major complication within the first 90 d. Other than blood transfusions given (86 patients [43.9%]), infectious, gastrointestinal, and procedural complications were the most common, at 16.2%, 14.1%, and 10.3%, respectively. Age, comorbidity, preoperative hematocrit, estimated blood loss, and length of surgery were predictive of a complication of any grade, while comorbidity, preoperative hematocrit, and orthotopic diversion were predictive of major complications. The 90-d mortality rate was 4.1%. The main limitation is lack of a control group. Analysis of postoperative morbidity following RARC demonstrates a considerable complication rate, though the rate is comparable to contemporary open series that followed similar reporting guidelines. This finding reinforces the need for complete and standardized reporting when evaluating surgical techniques and comparing published series. Copyright © 2012 European Association of Urology.

The acquisition of data and public discussion of complications after therapeutic procedures and surgeries is a sensitive subject, which is mostly avoided even in department meetings. However, it is evident that the broad discussion and the expression of different opinions and aspects provide useful information for continuous improvements. Therefore, we established a system for the transparent acquisition of complications in our department. Since January 2005, we systematically register operative and non-operative complications at our department, evaluate them and therefore gain a great benefit. All the complications are presented, discussed and evaluated within the weekly morbidity and mortality conferences. In 2005 and 2006, among a total number of 2730 and, respectively, 3124 operations, 102 (3.7 %) and 71 (2.3 %) complications have been registered and analysed according to different criteria. We have distinguished between complications which required surgery and complications which only required conservative treatment. There was a higher number of complications which needed surgery. In this group, the most common complications have been found in vertebral spine surgery. The groups of complications with conservative treatment were mostly related to nerve lesions and deep venous thrombosis. With the aid of the internal department evaluation of the registered data, especially the number of complications in vertebral spine surgery could be clearly reduced in 2006. The described method has created a transparency of occurring complications because each colleague is informed as well as involved in the solution process. Furthermore, it is planned to evaluate the impact of risk factors on the various performed surgeries. © Georg Thieme Verlag KG Stuttgart · New York.

Cerebral venous infarction: a potentially avoidable complication of deep brain stimulation surgery.

2013-01-01

Despite numerous reports on the morbidity and mortality of deep brain stimulation (DBS), cerebral venous infarction has rarely been reported. We present four cases of venous infarct secondary to DBS surgery. The diagnosis of venous infarction was based on 1) delayed onset of new neurologic deficits on postoperative day 1 or 2; 2) significant edema surrounding the superficial aspect of the implanted lead, with or without subcortical hemorrhage on CT scan. Four cases (0.8% per lead, 1.3% per patient) of symptomatic cerebral venous infarction were identified out of 500 DBS lead implantation procedures between July 2002 and August 2009. All four patients had Parkinson's disease. Their DBS leads were implanted in the subthalamic nucleus (n = 2), and the globus pallidus internus (n = 2). Retrospective review of the targeting confirmed that the planned trajectory passed within 3 mm of a cortical vein in two cases for which contrast-enhanced preoperative magnetic resonance (MR) imaging was available. In the other two cases, contrasted targeting images were not obtained preoperatively. Cerebral venous infarction is a potentially avoidable, but serious complication. To minimize its incidence, we propose the use of high-resolution, contrast-enhanced, T1-weighted MR images to delineate cerebral venous anatomy, along with careful stereotactic planning of the lead trajectory to avoid injury to venous structures. © 2013 International Neuromodulation Society.

[Use of pedicle percutaneous cemented screws in the management of patients with poor bone stock].

Management of patients with poor bone stock remains difficult due to the risks of mechanical complications such as screws pullouts. At the same time, development of minimal invasive spinal techniques using a percutaneous approach is greatly adapted to these fragile patients with a reduction in operative time and complications. The aim of this study was to report our experience with cemented percutaneous screws in the management of patients with a poor bone stock. Thirty-five patients were included in this retrospective study. In each case, a percutaneous osteosynthesis using cemented screws was performed. Indications were osteoporotic fractures, metastasis or fractures on ankylosing spine. Depending on radiologic findings, short or long constructs (2 levels above and below) were performed and an anterior column support (kyphoplasty or anterior approach) was added. Evaluation of patients was based on pre and postoperative CT-scans associated with clinical follow-up with a minimum of 6 months. Eleven men and 24 women with a mean age of 73 years [60-87] were included in the study. Surgical indication was related to an osteoporotic fracture in 20 cases, a metastasis in 13 cases and a fracture on ankylosing spine in the last 2 cases. Most of the fractures were located between T10 and L2 and a long construct was performed in 22 cases. Percutaneous kyphoplasty was added in 24 cases and a complementary anterior approach in 3 cases. Average operative time was 86minutes [61-110] and blood loss was estimated as minor in all the cases. In the entire series, average volume of cement injected was 1.8 cc/screw. One patient underwent a major complication with a vascular leakage responsible for a cement pulmonary embolism. With a 9 months average follow-up [6-20], no cases of infection or mechanical complication was reported. Minimal invasive spinal techniques are greatly adapted to the management of fragile patients. The use of percutaneous cemented screws is, in our experience, a valuable alternative for spinal fixation in patients with poor bone stock. This technique allows a good bony fixation with a low rate of complications. However, rigorous preoperative planning is necessary in order to avoid complications.

To report a single-center experience in rescue associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), after failure of previous portal embolization. We also performed a literature review. Between January 2014 and December 2015, every patient who underwent a rescue ALPPS procedure in Toulouse Rangueil University Hospital, France, was included. Every patient included had a project of major hepatectomy and a previous portal vein embolization (PVE) with insufficient future liver remnant to body weight ratio after the procedure. The ALPPS procedure was performed in two steps (ALPPS-1 and ALPPS-2), separated by an interval phase. ALPPS-2 was done within 7 to 9 d after ALPPS-1. To estimate the FLR, a computed tomography scan examination was performed 3 to 6 wk after the PVE procedure and 6 to 8 d after ALPPS-1. A transcystic stent was placed during ALPPS-1 and remained opened during the interval phase, in order to avoid biliary complications. Postoperative liver failure was defined using the 50-50 criteria. Postoperative complications were assessed according to the Dindo-Clavien Classification. From January 2014 to December 2015, 7 patients underwent a rescue ALPPS procedure. Median FLR before PVE, ALPPS-1 and ALPPS-2 were respectively 263 cc (221-380), 450 cc (372-506), and 660 cc (575-776). Median FLR/BWR before PVE, ALPPS-1 and ALPPS-2 were respectively 0.4% (0.3-0.5), 0.6% (0.5-0.8), and 1% (0.8-1.2). Median volume growth of FLR was 69% (18-92) after PVE, and 45% (36-82) after ALPPS-1. The combination of PVE and ALPPS induced a growth of median initial FLR of +408 cc (254-513), leading to an increase of +149% (68-199). After ALPPS-2, 4 patients had stage I-II complications. Three patients had more severe complications (one stage III, one stage IV and one death due to bowel perforation). Two patients suffered from postoperative liver failure according to the 50/50 criteria. None of our patients developed any biliary complication during the ALPPS procedure. Rescue ALPPS may be an alternative after unsuccessful PVE and could allow previously unresectable patients to reach surgery. Biliary drainage seems to reduce biliary complications.

Though the same types of complication were found in both elective cesarean section (ElCS) and emergence cesarean section (EmCS), the aim of this study is to compare the rates of maternal and fetal morbidity and mortality between ElCS and EmCS. Full-text articles involved in the maternal and fetal complications and outcomes of ElCS and EmCS were searched in multiple database. Review Manager 5.0 was adopted for meta-analysis, sensitivity analysis, and bias analysis. Funnel plots and Egger's tests were also applied with STATA 10.0 software to assess possible publication bias. Totally nine articles were included in this study. Among these articles, seven, three, and four studies were involved in the maternal complication, fetal complication, and fetal outcomes, respectively. The combined analyses showed that both rates of maternal complication and fetal complication in EmCS were higher than those in ElCS. The rates of infection, fever, UTI (urinary tract infection), wound dehiscence, DIC (disseminated intravascular coagulation), and reoperation of postpartum women with EmCS were much higher than those with ElCS. Larger infant mortality rate of EmCS was also observed. Emergency cesarean sections showed significantly more maternal and fetal complications and mortality than elective cesarean sections in this study. Certain plans should be worked out by obstetric practitioners to avoid the post-operative complications.

The purpose of this systematic review was to evaluate the literature to determine complications of hip arthroscopy, with a secondary focus on how to minimize complications and risks. Two independent reviewers performed a search of PubMed for articles that contained at least 1 of the following terms: complications and hip arthroscopy, hip impingement, femoral acetabular impingement and complications, or femoroacetabular impingement (FAI) and complications. The search was limited to articles published between 1999 and June 2013. An additional search was performed for articles evaluating techniques on how to minimize complications. We identified 81 studies (5,535 patients; 6,277 hips). The mean age was 35.48 years, and the mean body mass index was 25.20 kg/m(2). Of the participants, 52% were male and 48% were female. The majority of studies were Level IV Evidence (63%). A total of 285 complications were reported, for an overall rate of 4.5%. There were 26 major complications (0.41%) and a 4.1% minor complication rate. The overall reoperation rate was 4.03%. A total of 94 hips underwent revision arthroscopy. Regarding open procedures, 150 patients (93%) underwent either total hip arthroplasty or a hip resurfacing procedure. The conversion rate to total hip arthroplasty or a resurfacing procedure was 2.4%. Overall, primary hip arthroscopy is a successful procedure with low rates of major (0.41%) and minor (4.1%) complications. The reoperation rate was 4.03% in our review. There is admittedly a learning curve to performing hip arthroscopy, and we present a systematic review of the complications and how to minimize these complications with careful technique and planning.

Despite technological advances, studies continue to report high complication rates for atrial fibrillation (AF) ablation. We sought to review complication rates for AF ablation at a high-volume centre over a 14-year period and identify predictors of complications. We reviewed prospectively collected data from 2750 consecutive AF ablation procedures at our institution using radiofrequency energy (RF) between January 2004 and May 2017. All cases were performed under general anaesthetic with transoesophageal echocardiography (TEE), 3D-mapping and an irrigated ablation catheter. Double transseptal puncture was performed under TEE guidance. All patients underwent wide antral circumferential isolation of the pulmonary veins (30W anteriorly, 25W posteriorly) with substrate modification at operator discretion. Of 2255 initial and 495 redo procedures, ablation strategies were: pulmonary vein isolation (PVI) only 2097 (76.3%), PVI+lines 368 (13.4%), PVI+posterior wall 191 (6.9%), PVI+cavotricuspid isthmus 277 (10.1%). There were 23 major (0.84%) and 20 minor (0.73%) complications. Cardiac tamponade (five cases - 0.18%) and phrenic nerve palsy (one case - 0.04%) rates were very low. Major vascular complications necessitating surgery or blood transfusion occurred in five patients (0.18%). There were no cases of death, permanent disability, atrio-oesophageal fistulae or symptomatic pulmonary vein (PV) stenosis, although there were five TEE probe-related complications (0.18%). Female gender (OR 2.14; 95% CI 1.07-4.26) but not age >70 (OR 1.01) was the only multivariate predictor of complications. Atrial fibrillation ablation performed at a high-volume centre using RF can be achieved with a low major complication rate in a representative AF population over a sustained period of time.

Wound complications remain a significant source of morbidity for patients undergoing open infra-inguinal re-vascularization. The purpose of this study was to determine the impact of several infection-control strategies on post-operative wound complications after open infra-inguinal re-vascularization. A retrospective cohort study was conducted among all patients who underwent an open infra-inguinal re-vascularization procedure before and after 2014. Since 2014, we have implemented strategies to reduce post-operative wound complications, including: (1) Decreasing the use of incisional skin staples, (2) increasing the use of negative pressure wound therapy (NPWT) dressings, and (3) implementing an outpatient elective decontamination protocol for methicillin-resistant Staphylococcus aureus. "Pre-era" is defined as the period between January 2012 and December 2013, before the implementation of infection control strategies; "Post-era" is between January 2015 and August 2016, after implementation. The primary outcome of interest is 30-day wound complications (infection or dehiscence). Multi-variable logistic regression analysis was used to identify significant predictors of wound-related complications between the two cohorts. Propensity score adjustment controlled for baseline patient characteristics, peri-operative variables, and surgeon experience. A total of 338 open infra-inguinal procedures were performed: 175 in the pre-era and 163 in the post-era. Chlorhexidine skin preparation was used in the majority (321 [95%]) of cases. Comparing the periods, the post-era is characterized by a significant decrease in the use of groin staples (118 [67%] vs. 51 [31%], p < 0.001), and an increased application of NPWT dressings (6 [4%] vs. 66 [43%], p < 0.001). Thirty-five (37%) outpatient elective cases received the pre-operative decontamination protocol in the post-era. Compared with the pre-era, there was a decrease in the 30-day rate of wound complications (68 [39%] to 42 [26%], p = 0.011), and infection-related re-admissions (31 [17.7%] to 21 [12.9%], p = 0.220). When adjusting for patient characteristics, operative variables, and surgeon experience, post-era had significantly lower wound complications (odds ratio [OR] 0.33, p = 0.002) and re-operations (OR 0.16, p = 0.007). Among outpatient elective cases, the decontamination protocol was also independently associated with these two outcomes (wound complications: OR 0.05, p = 0.006; re-operations: 0.06, p = 0.002). The use of groin staples was an independent predictor of deep groin infections (OR 248, p < 0.001) and re-operations (OR 8.16, p = 0.032). Wound complications after open infra-inguinal re-vascularization have decreased significantly after the implementation of several infection-control strategies. Findings suggest that skin staples should be avoided in groin wounds, and anti-staphylococcal decontamination protocols decrease wound complications and prevent re-operations.

The perception of complications in pediatric spine surgery: a comparative survey of surgeons, caregivers and patients.

The perception of a surgical complication may differ between surgeons and patients. In pediatric spine surgery, the perception of the parent or primary caregiver may also differ. In order to better define these relationships, we performed a pilot study surveying a convenience sample of pediatric spinal surgeons, patients and their parent or primary caregiver. We hope to use this initial pilot study as a starting point for future research into this incompletely defined, yet increasingly relevant topic. A survey of case vignettes describing a potential perioperative complication was administered to 14 pediatric spine surgeons at the Texas Children's Hospital Pediatric NeuroSpine Clinic from June 1 to July 31, 2009. The same survey, with modified language, was presented to a group of 13 pediatric patients (age range: 12-18 years). In addition, the surveys were separately presented to 34 primary caregivers of pediatric patients evaluated in a spine surgery clinic. The 61 respondents were asked to evaluate the cases and determine if there was a minor, a major or no complication present. Fisher's exact test was employed to evaluate associations of respondent groups and complication severity. There were no statistically significant differences in the proportion of patients and caregivers rating the presence of complications. In 8 of 13 cases, a majority of surgeons and a majority of patients/caregivers felt a complication was present (all p > 0.06). A greater proportion of surgeons than patients/caregivers felt a complication was present in 2 cases of transient neurological deficit/paraparesis (6 weeks to 6 months; p < 0.04) and 1 case of cosmetically significant pressure sores to the face (p = 0.0002). A greater proportion of patients/caregivers identified a complication in a loss of range of motion after occipitocervical fusion (p < 0.0001) and a loss of motor evoked potentials without a neurological deficit. Amongst those who identified a complication, a greater proportion of surgeons considered the following as a 'major' complication: malpositioned spinal instrumentation with a return to the operating room (p = 0.02); transient new neurological deficit (p < 0.01), and deep wound infection with return to the operating room (p < 0.01). In no scenario did a greater proportion of patients/caregivers consider the complication 'major' compared to surgeons. In this pilot study, there appear to be differences in how postoperative complications are perceived by surgeons when compared to patients/caregivers. The importance of reconciling such differing opinions through open discussions between surgeons, patients and their families is integral to ensure congruent expectations of planned surgical interventions.

2016-08-01

In recent years, laparoscopy and robot-assisted procedures have become more commonplace in urology. Incorporation of these techniques into clinical practice requires extensive knowledge of the surgical approaches and complex instrumentation unique to minimally invasive surgery. In this review, focus will be directed to laparoscopic trocars including differing subtypes, placement in select urologic procedures, and proper use with emphasis on the avoidance of complications. Differing methods for the development of pneumoperitoneum and the associated risks of each will be discussed. The aim of this article is to provide a complete review of laparoscopic trocar use for the practicing urologist.

To demonstrate the different clinical presentations of tuberculous otitis media and the management of selected cases. We report four cases of tuberculous otitis media with different clinical presentations, encountered between 1998 and 2002. None of the cases showed improvement with local or systemic antibiotics. The diagnosis, complications and management of these cases are discussed. A high index of clinical suspicion of tuberculous otitis media is required in patients who do not respond to standard antibiotic therapy for (nontuberculous) chronic middle-ear infection. Early diagnosis and treatment of tuberculous otitis media is important to avoid irreversible complications, surgical intervention and propagation of the disease.

Since 2011, endoscopic correction of vesicoureteral reflux using dextranomer-hyaluronic acid copolymer (Deflux ® ) has been widely accepted in Japan due to its safety and minimally invasive nature. However, long-term complications are unknown. We present a case of Deflux ® implants calcification mimicking distal ureteral calculi in a 12-year-old boy with a history of Deflux ® injection performed at three years of age for primary VUR. We should be aware of this complication to avoid misdiagnosis and unnecessary invasive examination such as radiological imaging or endoscopy.

Septic abortion: a review of social and demographic characteristics.

Osazuwa, Henry; Aziken, Michael

2007-02-01

Septic abortion is a significant health problem with short- and long-term complications that affect the quality of life of those fortunate enough to avoid mortality. Both spontaneous and induced abortion can result in septic complications, with the latter disproportionately higher. Its incidence is high in environments with restrictive abortion laws, as clandestine procedures by non-doctors in unhygienic settings are prevalent. This study shows that it is still more common among teenagers and mainly performed by health professionals, which means that health care interventions should be re-evaluated and appropriately directed to preserve the reproductive health status of this vulnerable population.

For most patients with esophageal cancer, esophagectomy is an effective therapy. Perioperative management is critical for clinical outcomes after the operation. Great efforts should be made to avoid postoperative complications. We report myxedema coma, an emergency condition caused by severe hypothyroidism, after a patient underwent esophagectomy for esophageal cancer. The patient was successfully treated with intravenous levothyroxine. We strongly recommend that physicians test the thyroid hormone levels in patients with risk factors. If myxedema coma occurs, immediate use of intravenous levothyroxine is effective for this lethal complication. Copyright 2010 The Society of Thoracic Surgeons. Published by Elsevier Inc.

2013-05-01

The authors report a case of invasive aspergillosis of a sphenoid sinus mucocele revealed in a patient with diabetes in Djibouti by homolateral palsy of the 3rd, 4th, 5th and 6th nerves. This rare condition occurs preferentially in immunodeficient subjects. Because of its clinical polymorphism, its diagnosis is difficult and is often not made until complications develop. Endonasal surgery with anatomopathological and mycological examination is both a diagnostic and therapeutic procedure. It must be performed early, to avoid functional or even life-threatening complications.

2013-01-01

We report an unusual case of spontaneous ovarian hyperstimulation syndrome and pituitary hyperplasia mimicking macroadenoma in an adult, non-pregnant woman. Her condition was triggered by unrecognized primary hypothyroidism, which regressed after thyroid hormone replacement therapy. This case highlights the need for clinicians and radiologists to familiarize themselves with the clinical and imaging features detected in case of these complications of primary hypothyroidism, which are not well known in the medical and radiological profession. Such improved knowledge will help avoid delays in diagnosis, progression to life-threatening complications, and unnecessary surgery. PMID:23494012

Late-onset endophthalmitis secondary to exposed glaucoma tube implant in a rare case of paediatric glaucoma.

PubMed

Ranganath, Akshatha; Hashim, Adnan

2011-01-01

Glaucoma drainage implants (GDIs) are used to treat paediatric glaucoma resistant to conventional medical and surgical treatment, achieving good intraocular pressure (IOP) control and long-term success. Late endophthalmitis is a rare complication that may develop following GDI surgery. A 17-year-old male presented with acute endophthalmitis 2 years after Ahmed glaucoma valve implantation with pericardial patch graft for management of refractory glaucoma secondary to congenital ectropion uveae. The glaucoma tube was exposed due to erosion of the overlying conjunctiva with no visible pericardial graft. After control of active infection, he underwent tube revision surgery whereby the exposed tube was retained and repatched with a double-thickness pericardial patch graft. He did well following surgery with good control of IOP and restoration of vision. Conjunctival dehiscence with graft melting over the GDI tube presented a major risk factor for endophthalmitis. Prompt surgical revision of an exposed tube is highly recommended to avoid ocular morbidity.

[Anesthetic management for patients with mitochondrial disease].

PubMed

Imai, Yousuke; Yamada, Yoshitsugu

2014-01-01

Mitochondrial diseases are caused by a decrease in ATP production due to mutations of mitochondrial or mitochondria-related nuclear DNA. Their effects are likely to appear in tissues with a high energy demand, including skeletal muscle, nervous, and cardiovascular systems. Cardiac manifestations of mitochondrial diseases can be divided into cardiomyopathies, which are primarily hypertrophic and dilated cardiomyopathies, and electropathies, which are primarily conduction system disease and ventricular pre-excitation. The first principle of anesthesia for patients with mitochondrial diseases is to avoid any additional burden on the already declined metabolic functions. Appropriate oxygenation, minimization of the oxygen demand, stable cardiovascular management, maintenance of a normal blood glucose level and body temperature, and effective perioperative pain control are of importance. Most anesthetics have been reported to reduce mitochondrial functions, and although enhancement of the sensitivity and prolongation of the duration of action have been reported, they are clinically used with no major problems. Detailed preoperative evaluation of the disease condition and careful intraoperative monitoring are important for the prevention of perioperative complications.

Port positioning and docking for single-stage totally robotic dissection for rectal cancer surgery with the Si and Xi Da Vinci Surgical System.

Toh, James Wei Tatt; Kim, Seon-Hahn

2017-11-04

We have previously reported our technique of single-docking totally robotic dissection for rectal cancer surgery using the Da Vinci ® Si Surgical System in 2009. However, we have since optimised our port placement for the Si system and have developed a novel configuration of port placement and docking for the Da Vinci ® Xi Surgical System. We have performed over 700 cases using this technique with the Si system and have used our Xi technique since 2016 for totally robotic dissection for rectal cancer. We have kept the configuration of port placements for both the Xi and Si system as similar as possible, with the priorities to avoid arm collisions as well as to provide a workable port configuration of two left-handed instruments and one right-handed instrument. To date, there have had no major complications or arm collisions related to this technique of docking, port positioning and instrument placement.

Nitrous oxide in pediatric anesthesia: friend or foe?

PubMed

Schmitt, Erica L; Baum, Victor C

2008-06-01

Nitrous oxide has been used in clinical practice for over 150 years, often for pediatric procedures. Not only are there problems when used in patients with a variety of inborn errors of metabolism, but effects of nitrous oxide on the developing human brain are unknown. A recent adult human trial found that the use of nitrous oxide was associated with increased adverse outcome. Animal studies in several species have shown that nitrous oxide can be associated with apoptosis in the developing brain. Nitrous oxide can also inhibit major enzymatic pathways and repeated exposure may lead to neurologic damage. Single nucleotide polymorphisms in at least one of these enzymes are common in the population. There is a growing body of evidence that supports avoidance of nitrous oxide in both pediatric and adult patients, but the thousands of patients who have been exposed to nitrous oxide without apparent complications would suggest that further studies on long-term side effects and possible neurologic consequences need to be done.

A promising new device for the prevention of parastomal hernia.

PubMed

Hoffmann, Henry; Oertli, Daniel; Soysal, Savas; Zingg, Urs; Hahnloser, Dieter; Kirchhoff, Philipp

2015-06-01

Parastomal hernia (PSH) is the most frequent long-term stoma complication with serious negative effects on quality of life. Surgical revision is often required and has a substantial morbidity and recurrence rate. The development of PSH requires revisional surgery with a substantial perioperative morbidity and high failure rate in the long-term follow-up. Prophylactic parastomal mesh insertion during stoma creation has the potential to reduce the rate of PSH, but carries the risk of early and late mesh-related complications such as infection, fibrosis, mesh shrinkage, and/or bowel erosion. We developed a new stomaplasty ring (KORING), which is easy to implant, avoids potential mesh-related complications, and has a high potential of long-term prevention of PSH. Here we describe the technique and the first use. © The Author(s) 2014.

Central venous lines have become an integral part of patient care, but they are not without complications. Vertebral artery pseudoaneurysm formation is one of the rarer complications of central line placement. Presented is a rare case of two pseudoaneurysms of the vertebral and subclavian artery after an attempted internal jugular vein catheterization. These were successfully treated with open surgical repair and bypass. Open surgical repair remains the gold standard of treatment. Endovascular repair of vertebral artery pseudoaneurysms has been described with promising outcomes, but long-term results are lacking. Ultimately, the best treatment of these iatrogenic injuries should start with prevention. Well-documented techniques to minimize mechanical complications, including inadvertent arterial puncture, should be practiced and taught in training programs to avoid the potentially devastating consequences.

VAC-therapy is a closed-loop, non-invasive active system, characterised by a controlled and localized negative pressure applied on porous polyurethane absorbent foams. It promotes healing of acute and chronic wounds. Therapeutic effects of VAC-therapy have been proved and demonstrated, however this method can have some disadvantages. Even if it is a quite versatile device, only qualified medical/paramedical personnel should use it in order to avoid possible complications that can occur after an improper application. In this report, 11 cases of foam fragment retention within the wound are presented. This rare complication did not promote healing, but further hindered it. On the basis of our experience, it is mandatory to define indications, benefits and limitations of the VAC-therapy. PMID:23590296

Human altruism, evolution and moral philosophy

PubMed Central

2017-01-01

This paper has two central aims. The first is to explore philosophical complications that arise when we move from (i) explaining the evolutionary origins of genetically influenced traits associated with human cooperation and altruism, to (ii) explaining present manifestations of human thought, feeling and behaviour involving cooperation and altruism. While the former need only appeal to causal factors accessible to scientific inquiry, the latter must engage also with a distinctive form of explanation, i.e. reason-giving explanation, which in turn raises important philosophical questions, the answers to which will affect the nature of the ultimate explanations of our moral beliefs and related actions. On one possibility I will explore, this explanatory project cannot avoid engaging with first-order ethical theory. The second aim is to apply lessons from these explanatory complications to the critique of ‘evolutionary debunking arguments’, which seek to debunk morality, or at least objective construals of it (i.e. moral realism), by appeal to allegedly scientific debunking explanations of our moral beliefs that would defeat our justification for them. The explanatory complications brought out in the first half raise difficulties for such debunking arguments. If we avoid begging central philosophical questions then such debunking arguments pose little threat of saddling us with moral scepticism or subjectivism, though they do pose an important challenge for those developing a moral realist view.

Despite the widespread use of minimally invasive radical prostatectomy (MIRP), there remain concerns regarding its safety in patients with a history of prior abdominopelvic or inguinal surgery. A prospective database of 1165 MIRP procedures performed by a single surgeon at a high-volume tertiary care center from 2001 to 2013 was analyzed. After an initial period of transperitoneal MIRP (TP), an extraperitoneal (EP) approach was used preferentially beginning in 2005 (for both laparoscopic and robotic cases), and robotics were used preferentially beginning in 2010. Overall perioperative complications, major complications (Clavien-Dindo III or IV), and abdominal complications (e.g., ileus, bowel/organ injury, or vascular injury) were compared for patients with and without a prior surgical history. Uni- and multivariate logistic regression were used to control the impact of robotics, approach, operative time, estimated blood loss, case number, prostate weight, and primary Gleason on complications. Three hundred patients undergoing MIRP had prior abdominopelvic or inguinal surgery (25.8%). Of these, 102 (34%) underwent TP and 198 (66%) EP MIRP. Robotics was used in 286 cases (24.6%) and pure laparoscopy in 879 (75.4%). Complications occurred in 111 patients (9.5%) from the total cohort, with major complications in 32 (2.75%) and abdominal complications in 19 (1.63%). Prior surgery was not associated with overall, major, or abdominal complications. Of the controlling factors, only increasing operative time was associated with postoperative abdominal complications (most of which were ileus) on multivariate analysis. In this large single-surgeon series where both EP and TP approaches to MIRP are utilized, prior abdominopelvic or inguinal surgery was not associated with an increased risk of perioperative complications.

Type I thyroplasty has become a primary surgical choice for voice restoration in patients with glottal incompetence. This study examines factors associated with laryngeal complications after type I thyroplasty. Ten laryngoscopic variables were analyzed from preoperative, intraoperative, and postoperative videolaryngoscopies of 51 patients undergoing 58 medialization procedures. Ten patient and operative variables were examined by medical record review. Major complications were defined as wound hemorrhage, airway obstruction, or prosthesis extrusion. Minor complications were defined as vocal fold hematoma without airway obstruction or prosthesis movement. The major complication rate was 8.6%, and the minor complication rate was 29%. No delayed hemorrhage or airway obstruction occurred. Prosthesis extrusion occurred in five (8.6%) patients 1 week to 5 months after surgery. Extrusion was associated with suboptimal prosthesis placement in 80% of cases. Two patients retained excellent glottal closure despite extrusion. Vocal fold hematoma was identified in 14 (24%) cases and resolved within 1 week. Prosthesis movement occurred in three (5%) patients 1 week to 6 months after surgery and resulted in poor glottal closure. All patients with prosthesis extrusion or movement were female. Type I thyroplasty remains a safe outpatient procedure with few major complications. Prosthesis extrusion was associated with suboptimal prosthesis placement and may or may not result in poor glottal closure. Minor vocal fold hematomas were relatively frequent, resolved rapidly, and were not associated with airway obstruction. Female patients may be more prone to complications because of their small laryngeal size.

Purpose: New technologies for microwave ablation (MWA) have been conceived, designed to achieve larger areas of necrosis compared with radiofrequency ablation (RFA). The purpose of this study was to report complications by using this technique in patients with focal liver cancer. Methods: Members of 14 Italian centers used a 2.45-GMHz generator delivering energy through a cooled miniature-choke MW antenna and a standardized protocol for follow-up. They completed a questionnaire regarding number and type of deaths, major and minor complications and side effects, and likelihood of their relationship to the procedure. Enrollment included 736 patients with 1.037 lesions: 522 had hepatocellularmore » carcinoma with cirrhosis, 187 had metastases predominantly from colorectal cancer, and 27 had cholangiocellular carcinoma. Tumor size ranged from 0.5 to 10 cm. In 13 centers, the approach used was percutaneous, in 4 videolaparoscopic, and in 3 laparotomic. Results: No deaths were reported. Major complications occurred in 22 cases (2.9%), and minor complications in 54 patients (7.3%). Complications of MWA do not differ from those RFA, both being based on the heat damage. Conclusion: Results of this multicenter study confirmed those of single-center experiences, indicating that MWA is a safe procedure, with no mortality and a low rate of major complications. The low rate of complications was probably due to precautions adopted, knowing in advance possible risk conditions, on the basis of prior RFA experience.« less

Since the first deep brain stimulation (DBS) performed for movement disorder more than a decade ago, DBS has become a standard operation for advanced Parkinson's disease. Its indications are expanding to areas of dystonia, psychiatric conditions and refractory epilepsy. Additionally, a new set of DBS-related complications have arisen. Many teams found a slow learning curve from this complication-prone operation. We would like to investigate complications arising from 100 DBS electrode insertions and its prevention. We performed an audit in all DBS patients for operation-related complications in our centre from 1997 to 2008. Complications were classified into operation-related, hardware-related and stimulation-related. Operation-related complications included intracranial haemorrhages and electrode malposition. Hardware-related complications included fracture of electrodes, electrode migration, infection and erosion. Stimulation-related complications included sensorimotor conditions, psychiatric conditions and life-threatening conditions. From 1997 to the end of 2008, 100 DBS electrodes were inserted in 55 patients for movement disorders, mostly for Parkinsons disease (50 patients). There was one symptomatic cerebral haemorrhage (1%) and two electrode malpositions (2%). Meticulous surgical planning, use of microdriver and a reliable electrode anchorage device would minimise this group of complications. There were two electrode fractures, one electrode migration and one pulse-generator infection which contributed to the hardware-related complication rate of 5%. There were no sensorimotor or life-threatening complications in our group. However, three patients suffered from reversible psychiatric symptoms after DBS. DBS is, on the one hand, an effective surgical treatment for movement disorders. On the other hand, it is a complication-prone operation. A dedicated "Movement Disorder Team" consisting of neurologists, neurophysiologists, functional neurosurgeons, neuropsychologists and nursing specialists is essential. Liaison among team members in peri-operative periods and postoperative care is the key to avoiding complications and having a successful patient outcome.

Factors associated with neonatal ostomy complications.

Neonatal ostomies, either temporary or permanent, are created for numerous reasons. Limited attention has been given to understanding what factors might place infants at risk for surgical wound complications. The purpose of the study is to identify factors associated with risk of significant abdominal wound complications (wound dehiscence and wound infection) following neonatal ostomy creation. This is a retrospective chart review of infants undergoing ostomy between January 2009 and December 2013 at the University of Alberta Hospital. 66 infants were identified of which 18.2% (12/66) had wound complications. Variables associated with wound dehiscence included: findings of bowel necrosis during laparotomy (7/9 wound dehiscence, 18/57 none, p=0.008), perioperative sepsis (3/9 wound dehiscence, 3/57 none, p=0.006), and perioperative blood transfusion (9/9 wound dehiscence, 30/57 none, p=0.007). Wound infection was not predicted by any variables collected. Neonates undergoing creation of an ostomy appear to be at substantial risk for wound complications. As wound complications are significant issues for infants undergoing surgery, emerging strategies should be explored to either avoid ostomy creation or promote wound healing.

To identify major and minor complication rates associated with hip arthroscopy from a payer-based national database and compare with the rates reported in the existing literature. Patients who underwent hip arthroscopy between 2007 and 2014 were identified using PearlDiver, a publicly available database. Rates of major and minor complications, as well as conversion to total hip arthroscopy (THA), were determined by using Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision (ICD-9), codes. Incidence rates of select major complications across the entire database were used as a comparison group. Statistical significance was set at P < .05. Of 18 million patients screened from 2007 to 2014, a total of 2,581 hip arthroscopies were identified. The rates of major and minor complications within a 1-year postoperative period were 1.74% and 4.22%, respectively. Complications included heterotopic ossification (2.85%), bursitis (1.23%), proximal femur fracture (1.08%), deep vein thrombosis (0.79%), and hip dislocation (0.58%). The rate of conversion to THA within 1 year was 2.85%. When compared to rates in the general population, the relative risks [RRs] of requiring a THA (age <50 years, RR = 57.66, P < .001; age >50 years, RR = 22.05, P < .001), sustaining a proximal femur fracture (age <50 years, RR = 18.02, P < .001; age >50 years, RR = 2.23, P < .001), or experiencing a hip dislocation (RR 19.60, P < .001) at 1 year after hip arthroscopy were significantly higher in all age groups. Higher major complication rates after hip arthroscopy were observed using a national payer-based database than previously reported in the literature, especially in regard to hip dislocations and proximal femur fractures. Rates of total hip arthroplasty were similar to prior studies, whereas the rates of revision hip arthroscopy were higher. Level IV, case series.

2009-12-01

To prospectively evaluate the use of a single Arbeitsgemeinschaft für Osteosynthesefragen (AO) 2.0-mm locking reconstruction plate for linear noncomminuted mandibular fractures without the use of a second plate. We analyzed the clinical and radiologic data of 45 patients with 74 fractures (21 single fractures, 22 double fractures, and 2 triple fractures). Fracture locations were the symphysis (n = 35, 47.3%), body (n = 15, 20.3%), and angle (n = 24, 32.4%). We recorded the mechanism of injury, time between admission to the hospital and surgery, gender and age, temporary maxillomandibular fixation and its duration, and the surgical approach. Postsurgical complications that were recorded as minor did not require surgical intervention, whereas major complications required further surgical intervention. All patients had satisfactory fracture reduction and a successful treatment outcome without major complications. Ten patients (22.2%) developed minor complications. The present study has demonstrated that treating linear noncomminuted mandibular fractures with a single AO 2.0-mm locking reconstruction plates is associated with no major complications and sound bone healing in all patients.

Abstract Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea complications have been reported in Philadelphia-negative myeloproliferative neoplasms (MPNs), but their incidence and clinical consequences have not been defined in a large cohort of patients. We conducted a retrospective analysis of 188 consecutive patients with MPNs specifically addressing the incidence of these complications. Cyclical thrombocytosis was documented in 29 patients (15%), the majority of whom were receiving hydroxyurea. Acquired von Willebrand syndrome was identified in 17 of the 84 screened patients (20%), but was not associated with any major bleeding complications. Non-melanoma skin cancers were reported in 51 patients (27%). Hydroxyurea-related fever occurred in nine of 149 patients (6%) who received hydroxyurea. Seventy-three patients (39%) experienced a total of 98 major thrombotic events, with the majority of these occurring prior to or within 3 months of the diagnosis. Cyclical thrombocytosis, acquired von Willebrand syndrome, aggressive non-melanoma skin cancers and other hydroxyurea-related complications are not infrequent in MPNs and have important clinical consequences for management.

To evaluate the cost-effectiveness, from the funding body's point of view, of real-time ultrasound-guided central venous catheter insertion compared to the traditional method, which is based on the external anatomical landmark technique. A theoretical simulation based on international literature data was applied to the Brazilian context, i.e., the Unified Health System (Sistema Único de Saúde - SUS). A decision tree was constructed that showed the two central venous catheter insertion techniques: real-time ultrasonography versus external anatomical landmarks. The probabilities of failure and complications were extracted from a search on the PubMed and Embase databases, and values associated with the procedure and with complications were taken from market research and the Department of Information Technology of the Unified Health System (DATASUS). Each central venous catheter insertion alternative had a cost that could be calculated by following each of the possible paths on the decision tree. The incremental cost-effectiveness ratio was calculated by dividing the mean incremental cost of real-time ultrasound compared to the external anatomical landmark technique by the mean incremental benefit, in terms of avoided complications. When considering the incorporation of real-time ultrasound and the concomitant lower cost due to the reduced number of complications, the decision tree revealed a final mean cost for the external anatomical landmark technique of 262.27 Brazilian reals (R$) and for real-time ultrasound of R$187.94. The final incremental cost of the real-time ultrasound-guided technique was -R$74.33 per central venous catheter. The incremental cost-effectiveness ratio was -R$2,494.34 due to the pneumothorax avoided. Real-time ultrasound-guided central venous catheter insertion was associated with decreased failure and complication rates and hypothetically reduced costs from the view of the funding body, which in this case was the SUS.

[Complications of double j catheters and their endourological management].

PubMed

Pérez-Fentes, D

2016-10-01

The insertion of a double J catheter (DJ) has widespread, becoming a usual procedure and standard of care in urology. Despite its relative simplicity it is not free from intraoperative risks or problems during the weeks after the implant. Conversely, despite great advances in design of these catheters the ideal material has not been discovered yet, one that is perfectly biocompatible with urine and avoids completely the advent of complications. The range of problems associated with DJs is variable: from mild self-limited dysuria or hematuria to more complex situations with higher risk, such as catheter migration, complete calcification, breakage, obstruction and renal unit loss. The treatment of theses complications must combine maximal efficacy for their resolution with the least possible surgical aggression. Accordingly, the different options of endourological approach become very important and they are the cornerstone for the treatment of the complications associated with ureteral catheters. The objective of this review is to present the main complications derived from the insertion of a DJ, their diagnosis, prevention and treatment, focusing mainly in the different endourological techniques.

The lateral positioning used for the lateral suboccipital surgical approach is associated with various pathophysiologic complications. Strategies to avoid complications including an excessive load on the cervical vertebra and countermeasures against pressure ulcer development are needed. We retrospectively investigated positioning-related complications in 71 patients with cerebellopontine angle lesions undergoing surgery in our department between January 2003 and December 2010 using the lateral suboccipital approach. One patient postoperatively developed rhabdomyolysis, and another presented with transient peroneal nerve palsy on the unaffected side. Stage I and II pressure ulcers were noted in 22 and 12 patients, respectively, although neither stage III nor more severe pressure ulcers occurred. No patients experienced cervical vertebra and spinal cord impairments, brachial plexus palsy, or ulnar nerve palsy associated with rotation and flexion of the neck. Strategies to prevent positioning-related complications, associated with lateral positioning for the lateral suboccipital surgical approach, include the following: atraumatic fixation of the neck focusing on jugular venous perfusion and airway pressure, trunk rotation, and sufficient relief of weightbearing and protection of nerves including the peripheral nerves of all four extremities.

The persistence of attachment: complicated grief, threat, and reaction times to the deceased's name.

PubMed

Mancini, Anthony D; Bonanno, George A

2012-08-01

Complicated grief is increasingly recognized as a debilitating disorder with significant mental and health consequences. The underlying mechanisms of complicated grief remain unclear, however. In the present study, we investigated a specific mechanism of complicated grief (CG) derived from attachment theory: the accessibility of the deceased's mental representation under threat. In a matched comparison of complicated (n=26) and asymptomatic grievers (n=30), we used an emotional Stroop task following subliminal threat or neutral primes to examine the accessibility of mental representations of the deceased, current attachment figures, and close others. Complicated grievers did not evidence differential accessibility to the deceased's mental representation across priming conditions, whereas asymptomatic grievers showed reduced accessibility (deactivation) of the deceased's mental representation specifically in the threat prime condition. These effects were independent of depressive symptoms. Across grievers, attachment anxiety and avoidance uniquely predicted accessibility of the deceased's name in the threat condition. The limitations of this study are its small sample size and reliance on analog attachment threats. These data support that accessibility of the deceased's mental representation in threatening contexts is an important component of complicated and asymptomatic grieving and that attachment insecurity contributes to a maladaptive reliance on the deceased as an attachment figure.

Hauth, Elke A.M.; Drescher, Robert; Jansen, Christian

2006-08-15

Purpose. This prospective study was undertaken to determine the success rate, complications, and outcome of carotid artery stenting (CAS) without the use of cerebral protection devices. Methods. During 12 months, 94 high-grade stenoses of the carotid artery in 91 consecutive patients were treated. Sixty-six (70%) of the stenoses were symptomatic and 28 (30%) were asymptomatic. Results. In all 94 carotid stenoses CAS was successfully performed. During the procedure and within the 30 days afterwards, there were 2 deaths and 3 major strokes in the 66 symptomatic patients, resulting in a combined death and stroke rate of 5 of 66 (7%).more » Only one of these complications, a major stroke, occurred during the procedure. In the 6-month follow-up, one additional major stroke occurred in a originally symptomatic patient resulting in a combined death and stroke rate of 6 of 66 (10%) for symptomatic patients at 6 months. No major complications occurred in asymptomatic patients during the procedure or in the 6-month follow-up period. At 6 months angiographic follow-up the restenosis rate with a degree of >50% was 3 of 49 (6%) and the rate with a degree of {>=}70% was 1 of 49 (2%). Conclusions. Cerebral embolization during CAS is not the only cause of the stroke and death rate associated with the procedure. The use of cerebral protection devices during the procedure may therefore not prevent all major complications following CAS.« less

Secondary and tertiary preventions of thyroid disease.

2018-05-01

Secondary and tertiary preventions are concerned with the recognition of the disease process in a very early stage and delay in progression to complete disease and minimization of complications and the impact of illness. All articles related to secondary and tertiary prevention of thyroid diseases were reviewed. Using related key words, articles published between 2001 and 2015 were evaluated, categorized, and analyzed. In secondary prevention, congenital hypothyroidism and subclinical hypo and hyperthyroidism are equally important. Routine screening of patients with multinodular goiter by either ultrasonography or calcitonin is a controversial issue, while calcitonin assessments in medullary cancer and RET in family members are recommended. Screening of thyroid disease in pregnancy is limited to those with risk factors. Views regarding the importance of thyroid autoimmunity in secondary prevention are also presented. In tertiary prevention, prescribing excessive doses of levothyroxine, in the elderly in particular and appropriate care of all patients to avoid progression and complications are the key issues. Optimization of management of thyroid diseases requires timely screening, prevention of progression to more sever disease, optimal medical care, and avoidance of iatrogenic conditions.

Is electroconvulsive therapy safe in the presence of an intracranial metallic object?: case report and review of the literature.

PubMed

Mortier, Philippe; Sienaert, Pascal; Bouckaert, Filip

2013-09-01

Little is known about the use of electroconvulsive therapy (ECT) in patients with intracranial metallic objects. Theoretically, electric current might cause heating of the metal and damage of the surrounding brain tissue. Moreover, intracranial foreign objects increase the risk for epileptic phenomena and could thus complicate the treatment course. The case of a man with intracranial bullet fragments as a result of a headshot, treated with ECT for mania, is presented. We conducted a PubMed literature search for other relevant cases. In our patient, ECT was completed without complication. Electroconvulsive therapy was safely administered in 22 published cases of patients with intracranial metallic objects. After carefully weighing benefits and risks in each individual case, psychiatrists should not be reluctant to use ECT in patients with intracranial metallic objects. Apart from avoiding empirical dosage titration to minimize the exposure to current, positioning the electrodes to avoid the electric current of heating the metal, and continuing antiepileptic agents in high-risk patients, no precautions need to be considered.

Closed geometric models in medical applications

1996-04-01

Conventional surface fitting methods give twisted surfaces and complicates capping closures. This is a typical character of surfaces that lack rectangular topology. We suggest an algorithm which overcomes these limitations. The analysis of the algorithm is presented with experimental results. This algorithm assumes the mass center lying inside the object. Both capping closure and twisting are results of inadequate information on the geometric proximity of the points and surfaces which are proximal in the parametric space. Geometric proximity at the contour level is handled by mapping the points along the contour onto a hyper-spherical space. The resulting angular gradation with respect to the centroid is monotonic and hence avoids the twisting problem. Inter-contour geometric proximity is achieved by partitioning the point set based on the angle it makes with the respective centroids. Avoidance of capping complications is achieved by generating closed cross curves connecting curves which are reflections about the abscissa. The method is of immense use for the generation of the deep cerebral structures and is applied to the deep structures generated from the Schaltenbrand- Wahren brain atlas.

2016-09-20

To report postoperative complications using a commercially available porous-coated press-fit cementless total hip replacement (THR) system in dogs. Medical records were reviewed for client-owned dogs with hip pathologies requiring THR. A minimum of six-week postoperative orthopaedic examination and orthogonal pelvic radiographs were used to assess outcome and complications in the perioperative period. Referring veterinarian medical records, phone interviews with clients, or both were used to assess long-term functional outcome and complications. Bilateral THR was performed in 36 dogs, and unilateral in 147 dogs, making a total of 219 THR procedures in 183 dogs. A total complication rate of 31.1% (68/219) was observed. A catastrophic complication was observed in 8.2% (n = 18), a major complication in 9.6% (n = 21), and a minor complication in 13.2% (n = 29) of procedures. The most common complications were intra-operative femoral fissure (n = 46), diaphyseal femoral fracture (n = 15), and coxofemoral luxation (n = 9). Full return to function was achieved in 88.1% of procedures with a median follow-up period of 42 months. Porous-coated press-fit cementless collarless total hip replacements have a high complication rate. The majority of complications occur intra-operatively or perioperatively, with few complications occurring beyond 12 weeks postoperatively. Both fissure fractures and diaphyseal femoral fractures carry a favourable prognosis with immediate cerclage wiring and plate fixation, respectively.

Major lower extremity amputations continue to be associated with significant morbidity and mortality, yet few recent large series have evaluated factors associated with perioperative mortality and wound complications. The purpose of this study was to examine factors affecting perioperative mortality and wound-related complications following major lower extremity amputation. A retrospective review was conducted of all adult patients who underwent nontraumatic major lower extremity amputations over a 5-year period at a single tertiary-care center in southern West Virginia. Demographic and clinical data, perioperative data, and outcomes were collected and analyzed to identify any relationship with perioperative mortality, as well as wound complications and early revisions (within 90 days) to a more proximal level. Variables were examined using chi-squared, two-tailed t-tests, and logistic regression. Three hundred eighty patients (61% male) underwent 412 major lower extremity amputations during 1999-2003. The initial level of amputation included 230 below-knee (BKA), 149 above-knee (AKA), and one hip disarticulation. Perioperative mortality was 15.5% (n = 59). From a regression model, age, albumin level, AKA, and lack of a previous coronary artery bypass graft (CABG) were independently related to mortality. Patients who did not have a previous CABG were nearly three times more likely to die than those who did (p = 0.038). Overall early wound complications were noted in 13.4% (n = 51). Four factors were independently related to experiencing a 90-day wound complication: BKA, community (rather than care facility) living, type of anesthesia, and preoperative hematocrit >30%. Major lower extremity amputation in patients with peripheral vascular disease continues to be associated with considerable perioperative morbidity and mortality. Even though the surgical procedure itself may not be challenging from a technical standpoint, underlying medical conditions put this group at high risk for perioperative death. Wound-healing problems are frequently encountered and must be minimized to facilitate early mobilization and hospital discharge.

Acute primary resection as treatment for left-sided colonic obstruction (LSCO) is notorious for its high morbidity and mortality rates. Both stenting and loop colostomy construction can serve as a bridge to surgery, hereby avoiding the high morbidity and mortality rates associated with emergency resections. This study aims to investigate the safety of a loop colostomy in patients presenting with acute LSCO. Retrospective analysis of all patients that received a loop colostomy for LSCO between 2003 and 2015 was performed. Primary outcomes were mortality, major morbidity (Clavien-Dindo grades III-IV) and minor morbidity (Clavien-Dindo grades I-II). One hundred forty-six patients presenting with acute LSCO received a diverting colostomy. After colostomy construction, mortality occurred in four patients (2.7%) and major complications were reported in 20 patients (13.7%). In 61 patients, the diverting colostomy served as a palliative measure, because of metastatic disease or unfitness for major surgery. The remaining 85 patients all underwent delayed resection, resulting in an overall mortality, major morbidity and minor morbidity of 6.9% (n = 6), 14.0% (n = 12) and 26.7% (n = 23), respectively. Diverting colostomy construction is a minimally invasive and safe treatment option for LSCO. It can serve as a definite palliative measure, as well as a bridge to elective surgery. A diverting colostomy as a bridge to surgery might even be a valid alternative for emergency resections, since mortality and morbidity rates following colostomy construction and delayed resection appear lower than reported outcomes following primary resection.

Interinstitutional consultation in pathology has shown to improve patient safety by detecting interpretive errors that may significantly impact clinical management. We conducted a study of 922 cases of thyroid FNAC slides, referred to our institution over a 2-year period, to assess the magnitude of discrepancies and determine the clinical impact of second opinion. Disagreements were categorized as none, minor or major, the latter two defined as one- or two-step deviations respectively on the NCI diagnostic categories scale. There were 122 disagreements (13%), including 44 major and 78 minor. Seventy-five patients underwent a change in management based on second opinion, in conjunction with clinical and radiologic findings (age, size of nodule, family history, ultrasonographic appearance, and solitary versus multiple nodules). The second opinion was supported on follow-up in 57% of major discrepancies, and the initial diagnosis was concurrent with the surgical diagnosis in 7% cases. The remainder (36%) of major discrepancy cases did not undergo surgery, precluding tissue confirmation. Critics have alleged increased costs due to interinstitutional consultations. However, cost avoidance from lost wages, potential surgical complications, and litigation is not easily quantified. Using a simplified calculation to objectively measure the costs associated with changed diagnoses, we estimate that second opinion of these 922 cases resulted in potential cost saving of $940,166 based on current Medicare reimbursement codes. Our study indicates the need for a quality-control program of outside thyroid FNA slides, especially in "high discrepancy categories" as discussed in the article. Copyright © 2011 Wiley-Liss, Inc.

Botulinum Toxin A for Oral Cavity Cancer Patients: In Microsurgical Patients BTX Injections in Major Salivary Glands Temporarily Reduce Salivary Production and the Risk of Local Complications Related to Saliva Stagnation

PubMed Central

In patients suffering from oral cavity cancer surgical treatment is complex because it is necessary to remove carcinoma and lymph node metastasis (through a radical unilateral or bilateral neck dissection) and to reconstruct the affected area by means of free flaps. The saliva stagnation in the post-operative period is a risk factor with regard to local complications. Minor complications related to saliva stagnation (such as tissue maceration and wound dehiscence) could become major complications compromising the surgery or the reconstructive outcome. In fact the formation of oro-cutaneous fistula may cause infection, failure of the free flap, or the patient’s death with carotid blow-out syndrome. Botulinum injections in the major salivary glands, four days before surgery, temporarily reduces salivation during the healing stage and thus could reduce the incidence of saliva-related complications. Forty three patients with oral cancer were treated with botulinum toxin A. The saliva quantitative measurement and the sialoscintigraphy were performed before and after infiltrations of botulinum toxin in the major salivary glands. In all cases there was a considerable, but temporary, reduction of salivary secretion. A lower rate of local complications was observed in the post-operative period. The salivary production returned to normal within two months, with minimal side effects and discomfort for the patients. The temporary inhibition of salivary secretion in the post-operative period could enable a reduction in saliva-related local complications, in the incidence of oro-cutaneous fistulas, and improve the outcome of the surgery as well as the quality of residual life in these patients.

This study retrospectively evaluates complications after lung radiofrequency ablation (RFA). Complications were assessed for each RFA session in 420 consecutive patients with 1403 lung tumors who underwent 1000 RFA sessions with a cool-tip RFA system. A major complication was defined as a grade 3 or 4 adverse event. Risk factors affecting frequent major complications that occurred with an incidence of 1% or more were detected using multivariate analysis. Four deaths (0.4% [4/1000]) related to RFA procedures occurred. Three patients died of interstitial pneumonia. The other patient died of hemothorax. The major complication rate was 9.8% (98/1000). Frequent major complications were aseptic pleuritis (2.3% [23/1000]), pneumonia (1.8% [18/1000]), lung abscess (1.6% [16/1000]), bleeding requiring blood transfusion (1.6% [16/1000]), pneumothorax requiring pleural sclerosis (1.6% [16/1000]), followed by bronchopleural fistula (0.4% [4/1000]), brachial nerve injury (0.3% [3/1000]), tumor seeding (0.1% [1/1000]), and diaphragm injury (0.1% [1/1000]). Puncture number (p < 0.02) and previous systemic chemotherapy (p < 0.05) were significant risk factors for aseptic pleuritis. Previous external beam radiotherapy (p < 0.001) and age (p < 0.02) were significant risk factors for pneumonia, as were emphysema (p < 0.02) for lung abscess, and serum platelet count (p < 0.002) and tumor size (p < 0.02) for bleeding. Emphysema (p < 0.02) was a significant risk factor for pneumothorax requiring pleural sclerosis. Lung RFA is a relatively safe procedure, but it can be fatal. Risk factors found in this study will help to stratify high-risk patients.

Patients with diverticular disease are frequently advised to avoid eating nuts, corn, popcorn, and seeds to reduce the risk of complications. However, there is little evidence to support this recommendation. To determine whether nut, corn, or popcorn consumption is associated with diverticulitis and diverticular bleeding. The Health Professionals Follow-up Study is a cohort of US men followed up prospectively from 1986 to 2004 via self-administered questionnaires about medical (biennial) and dietary (every 4 years) information. Men reporting newly diagnosed diverticulosis or diverticulitis were mailed supplemental questionnaires. The study included 47,228 men aged 40 to 75 years who at baseline were free of diverticulosis or its complications, cancer, and inflammatory bowel disease and returned a food-frequency questionnaire. Incident diverticulitis and diverticular bleeding. During 18 years of follow-up, there were 801 incident cases of diverticulitis and 383 incident cases of diverticular bleeding. We found inverse associations between nut and popcorn consumption and the risk of diverticulitis. The multivariate hazard ratios for men with the highest intake of each food (at least twice per week) compared with men with the lowest intake (less than once per month) were 0.80 (95% confidence interval, 0.63-1.01; P for trend = .04) for nuts and 0.72 (95% confidence interval, 0.56-0.92; P for trend = .007) for popcorn. No associations were seen between corn consumption and diverticulitis or between nut, corn, or popcorn consumption and diverticular bleeding or uncomplicated diverticulosis. In this large, prospective study of men without known diverticular disease, nut, corn, and popcorn consumption did not increase the risk of diverticulosis or diverticular complications. The recommendation to avoid these foods to prevent diverticular complications should be reconsidered.

Tibiocalcaneal Arthrodesis With a Porous Tantalum Spacer and Locked Intramedullary Nail for Post-Traumatic Global Avascular Necrosis of the Talus.

PubMed

Cohen, Michael M; Kazak, Marat

2015-01-01

Global avascular necrosis of the talus is a devastating complication that usually occurs as a result of a post-traumatic or metabolic etiology. When conservative options fail, tibiocalcaneal arthrodesis is generally indicated in conjunction with massive bone grafting to maintain the functional length of the extremity. Several bone grafting options are available, including the use of a freeze-dried or fresh-frozen femoral head allograft or autograft obtained from the iliac crest or fibula, all of which pose their own inherent risks. The noted complications with massive bone grafting techniques have included graft collapse, infection, immune response, donor site morbidity, and nonunion. In an effort to avoid many of these complications, we present a case report involving post-traumatic talar avascular necrosis in a 59-year-old male who was successfully treated with the use of a porous tantalum spacer, an autogenic morselized fibular bone graft, and 30 mL of bone marrow aspirate in conjunction with a retrograde tibiocalcaneal nail. Porous tantalum is an attractive substitute for bone grafting because of its structural integrity, biocompatibility, avoidance of donor site complications, and lack of an immune response. The successful use of porous tantalum has been well-documented in hip and knee surgery. We present a practical surgical approach to tibiotalocalcaneal arthrodesis with a large segmental deficit. To our knowledge, this is the first published report describing an alternative surgical technique to address global avascular necrosis of the talus that could have additional applications in salvaging the ankle with a large bone deficiency.

The management of the recall is complicated by the competing risks of lead failure and complications that can occur with lead revision. Many of these patients are currently undergoing an elective generator change--an ideal time to consider lead revision. To determine the cost-effectiveness of a proactive management strategy for the Sprint Fidelis recall. We obtained detailed clinical outcomes and costing data from a retrospective analysis of 341 patients who received the Sprint Fidelis lead in British Columbia, where patients younger than 60 years were offered lead extraction when undergoing generator replacement. These population-based data were used to construct and populate a probabilistic Markov model in which a proactive management strategy was compared to a conservative strategy to determine the incremental cost per lead failure avoided. In our population, elective lead revisions were half the cost of emergent revisions and had a lower complication rate. In the model, the incremental cost-effectiveness ratio of proactive lead revision versus a recommended monitoring strategy was $12,779 per lead failure avoided. The proactive strategy resulted in 21 fewer failures per 100 patients treated and reduced the chance of an additional complication from an unexpected surgery. Cost-effectiveness analysis suggests that prospective lead revision should be considered when patients with a Sprint Fidelis lead present for pulse generator change. Elective revision of the lead is justified even when 25% of the population is operated on per year, and in some scenarios, it is both less costly and provides a better outcome. © 2013 Heart Rhythm Society Published by Heart Rhythm Society All rights reserved.

Dysphagia, aspiration, and potential pneumonia represent a major source of morbidity in patients undergoing lung transplantation. Conditions that potentiate dysphagia and aspiration include frailty and prolonged intubation. Our group of speech-language pathologists has been actively involved in performance of a bedside evaluation of swallowing, and instrumental evaluation of swallowing with modified barium swallow, and postoperative management in patients undergoing lung transplantation. All lung transplant patients from April 2009 to September 2012 were evaluated retrospectively. A clinical bedside examination was performed by the speech-language pathology team, followed by a modified barium swallow or fiberoptic endoscopic evaluation of swallowing. A total of 321 patients were referred for evaluation. Twenty-four patients were unable to complete the evaluation. Clinical signs of aspiration were apparent in 160 patients (54%). Deep laryngeal penetration or aspiration were identified in 198 (67%) patients during instrumental testing. A group of 81 patients (27%) had an entirely normal clinical examination, but were found to have either deep penetration or aspiration. The majority of patients aspirate after lung transplantation. Clinical bedside examination is not sensitive enough and will fail to identify patients with silent aspiration. A standard of practice following lung transplantation has been established that helps avoid postoperative aspiration associated with complications. Copyright © 2017 The Society of Thoracic Surgeons.

To analyze the role of different procedures in the management of pancreatic stump according to the incidence of postoperative morbidity derived from the data of a single center surgical population. From 1989 to 2005 we performed 76 pancreaticoduodenectomies (PD) and 26 distal pancreatectomies (DP). The surgical reconstruction after PD was as follows: 11 manual non-absorbable stitches closure of the main duct, 24 closures of the main duct with linear stapler, 17 occlusions of the main duct with neoprene glue and 24 duct-to-mucosa anastomosis. In the PD group, the morbidity rate was 60%, caused by: pancreatic leakage in 48% of patients, hemorrhagic complications in 10% following surgical procedure and infectious complications in 15%. After DP we recorded: leakage in 3.9%, haemoperitoneum in 15.4% and no complications in 80.7%. The multivariate analysis showed that the in-hospital mortality was linked to the surgical procedure (PD, p=0.003) and to the following complications: pancreatic leakage (p=0.004), haemoperitoneum (p=0.00045) and infectious complications (p=0.0077). Bleeding complications, biliary anastomosis leakage and infectious complications were consequences of pancreatic leakage (p=0.025, p=0.025 and p=0.025 respectively). Manual non-absorbable stitch closure of the main duct and occlusion of the main duct with neoprene glue should be avoided in the reconstructive phase.

Complications of Minimally Invasive Cosmetic Procedures: Prevention and Management

2012-01-01

Over the past decade, facial rejuvenation procedures to circumvent traditional surgery have become increasingly popular. Office-based, minimally invasive procedures can promote a youthful appearance with minimal downtime and low risk of complications. Injectable botulinum toxin (BoNT), soft-tissue fillers, and chemical peels are among the most popular non-invasive rejuvenation procedures, and each has unique applications for improving facial aesthetics. Despite the simplicity and reliability of office-based procedures, complications can occur even with an astute and experienced injector. The goal of any procedure is to perform it properly and safely; thus, early recognition of complications when they do occur is paramount in dictating prevention of long-term sequelae. The most common complications from BoNT and soft-tissue filler injection are bruising, erythema and pain. With chemical peels, it is not uncommon to have erythema, irritation and burning. Fortunately, these side effects are normally transient and have simple remedies. More serious complications include muscle paralysis from BoNT, granuloma formation from soft-tissue filler placement and scarring from chemical peels. Thankfully, these complications are rare and can be avoided with excellent procedure technique, knowledge of facial anatomy, proper patient selection, and appropriate pre- and post-skin care. This article reviews complications of office-based, minimally invasive procedures, with emphasis on prevention and management. Practitioners providing these treatments should be well versed in this subject matter in order to deliver the highest quality care. PMID:23060707

Background: The use of the intra-aortic balloon pump (IABP) as a support device remains controversial due to the fact that a number of studies have shown no benefit in end mortality whilst using this device. One of the reasons for this could be the increase in vascular complications when using the pump. Therefore, the aim of the present review was to assess the current literature available with regards to IABP vascular complications during the clinical situation. Methods: A literature search was performed, searching for IABP complications in adult human studies between 1990 and 2016. Results: A total of 20 reports were identified as fitting the criteria of this study. The majority of vascular complications were limb ischemia, bleeding or mesenteric ischemia. The overall incidence of vascular complications ranged from 0.94% to 31.1%. Diabetes, peripheral vascular disease and hypertension, as well as smoking were all identified as risk factors for complications following IABP. Furthermore, studies supported the use of sheathless balloon insertion to reduce the risk of complications. Conclusion: Major vascular complications, including limb and mesenteric ischemia as well as bleeding and hemorrhage, have been associated with IABP. However, the incidence of these complications was generally low. Further studies are still required to truly understand the risk/benefit associated with the use of IABP. PMID:28816093

2016-10-01

Skin expansion is a difficult and long process in which can occur more or less serious complications. Overall complications rates describe in the literature vary between 13 and 37%. We can categorize them in major complications, which can lead to a failure maybe even an aggravation of the anterior status, and in minor complications that do not compromise the expansion process but can alter it. The main major complications are infection, skin suffering and necrosis which can lead to prosthesis exposition, leaks and technical problems with equipment dysfunctions that may cause difficulties or a failure of the inflations. The main minor complications are hematomas, seromas, valve or tube exposition, pains with paraesthesias caused by neighbouring organs compression, pathologic and unsightly scares and can lead to an important psychological impact. These complications can be due to a precarious skin's state, a material dysfunction or unpredictable technical problems but also by an inappropriate preoperative indication or planning. The emerging of a complication, however, is not synonymous to a failure of the procedure; a satisfactory reconstruction may still be obtained in 75% of all cases. The purpose of this article is to help to identify the situations at risk of complications in order to prevent, detect and treat them early. Copyright © 2016 Elsevier Masson SAS.

2002-01-01

Creating and implementing a process for the mitigation of the impact hazards due to cornets and asteroids will prove to be a complex and involved process. The closest similar program is the collision avoidance process currently used for protection of the International Space Station (ISS). This process, in operation for over three years, has many similarities to the NEG risk problem. By reviewing the ISS program, a broader perspective on the complications of and requirements for a NEO risk mitigation program might be obtained. Specifically, any lessons learned and continuing issues of concern might prove useful in the development of a NEO risk assessment and mitigation program.

Correcting prominent ears with the island technique.

PubMed

DeMoura, L F

1977-01-01

A surgical procedure is described which corrects the ansiform ear by repositioning and reconstructing the anthelix and the anterior crus with the formation of the triangular fossa. This corrects the scaphoconchal angle and improves the cephaloauricular angle, overcoming the problem of prominent ears. Correction in early childhood is recommended in order to avoid personality problems that may result from the deformity, particularly in boys. The technique employed yields important advantages: (1) prolonged use of the helmet-type of surgical dressing is unnecessary; (2) scars are less conspicuous; (3) the outcome is attractive and normal; (4) bleeding and inflammatory complications are avoided; and (5) recurrence of the malformation is unlikely.

[The key points of prevention for special surgical complications after radical operation of gastric cancer].

2017-02-25

Incidence of gastric cancer is high in China and standard radical operation is currently the main treatment for gastric cancer. Postoperative complications, especially some special complications, can directly affect the prognosis of patients, even result in the increase of mortality. But the incidences of these special complications are low, so these complications are often misdiagnosed and delayed in treatment owing to insufficient recognition of medical staff. These special complications include (1) Peterson hernia: It is an abdominal hernia developed in the space between Roux loop and transverse colon mesentery after Roux-Y reconstruction of digestive tract. Peterson hernia is rare and can quickly result in gangrenous ileus. Because of low incidence and without specific clinical symptoms, this hernia does not attract enough attention in clinical practice, so the outcome will be very serious. Once the diagnosis is made, an emergent operation must be performed immediately. Peterson space should be closed routinely in order to avoid the development of hernia. (2) Lymphatic leakage: It is also called chyle leakage. Cisterna chylus is formed by gradual concentration of extensive lymphatic net to diaphragm angle within abdominal cavity. Lymphadenectomy during operation may easily damage lymphatic net and result in leakage. The use of ultrasonic scalpel can decrease the risk of lymphatic leakage in certain degree. If lymphatic leakage is found during operation, transfixion should be performed in time. Treatment includes total parenteral nutrition, maintenance of internal environment, supplement of protein, and observation by clamp as an attempt. (3)Duodenal stump leakage: It is one of serious complications affecting the recovery and leading to death after subtotal gastrectomy. Correct management of duodenal stump during operation is one of key points of the prevention of duodenal stump leakage. Routine purse embedding of duodenal stump is recommend during operation. The key treatment of this complication is to promt diagnosis and effective hemostasis.(4) Blood supply disorder of Roux-Y intestinal loop: Main preventive principle of this complication is to pay attention to the blood supply of vascular arch in intestinal edge. (5) Anastomotic obstruction by big purse of jejunal stump: When Roux-en-Y anastomosis is performed after distal radical operation for gastric cancer, anvil is placed in the remnant stomach and anastomat from distal jejunal stump is placed to make gastrojejunal anastomosis, and the stump is closed with big purse embedding. The embedding jejunal stump may enter gastric cavity leading to internal hernia and anastomotic obstruction. We suggest that application of interruptable and interlocking suture and fixation of stump on the gastric wall can avoid the development of this complication.

Implantation of Ahmed glaucoma valve is an effective surgical technique to reduce intraocular pressure in patients affected with glaucoma. While in the past, the use of this device was reserved to glaucoma refractory to multiple filtration surgical procedures, up-to-date mounting experience has encouraged its use also as a primary surgery for selected cases. Implantation of Ahmed glaucoma valve can be challenging for the surgeon, especially in patients who already underwent previous multiple surgeries. Several tips have to be acquired by the surgeon, and a long learning curve is always needed. Although the valve mechanism embedded in the Ahmed glaucoma valve decreases the risk of postoperative hypotony-related complications, it does not avoid the need of a careful follow-up. Complications related to this type of surgery include early and late postoperative hypotony, excessive capsule fibrosis around the plate, erosion of the tube or plate edge, and very rarely infection. The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications.

The aim of this review is to describe surgical technique for Ahmed glaucoma valve implantation and to report related complications. PMID:28255226

Despite advances in patient and graft management, biliary complications (BC) still represent a challenge both in the early and delayed period after orthotopic liver transplantation (OLT). Because of unspecific clinical presentation, imaging is often mandatory in order to diagnose BC. Among imaging modalities, magnetic resonance cholangiography (MRC) has gained widespread acceptance as a tool to represent the reconstructed biliary tree noninvasively, using both the conventional technique (based on heavily T2-weighted sequences) and contrast-enhanced MRC (based on the acquisition of T1-weighted sequences after the administration of hepatobiliary contrast agents). On this basis, MRC is generally indicated to: (1) avoid unnecessary procedures of direct cholangiography in patients with a negative examination and/or identify alternative complications; and (2) provide a road map for interventional procedures or surgery. As illustrated in the review, MRC is accurate in the diagnosis of different types of biliary complications, including anastomotic strictures, non-anastomotic strictures, leakage and stones.

Recent studies reviewing large patient databases suggested that age may be an independent risk factor for abdominoplasty. However, these investigations by design considered only short-term major complications. The purpose of this investigation was: (1) to compare the safety of abdominoplasty in an elderly and younger patient population; (2) to determine the complication rates across all spectrums: major, minor, local, and systemic; and (3) to evaluate complications occurring both short and long term. Abdominoplasty procedures performed from 2010 to 2015 were retrospectively reviewed. Subjects were divided into two groups: ≤59 years old and ≥60 years old. Major, minor, local, and systemic complications were analyzed. Patient demographics, comorbidities, perioperative details, adjunctive procedures were also assessed. A total of 129 patients were included in the study: 43 in the older and 86 in the younger age group. The median age of The elderly and young groups was 65.0 and 41.5 years, respectively (P < .001). No statistically significant differences in major, minor, local, or systemic complications were found when both age groups were compared. Major local, major systemic, minor local, and minor systemic in the elderly were 6.9%, 2.3%, 18.6%, and 2.3%, while in the younger patients were 9.3%, 4.7%, 10.5%, and 0.0%, respectively (P > .05). Median follow-up time of the elderly (4.0 months) was no different than the younger (5.0 months) patients (P > .07). Median procedure time in the elderly (4.5 hours) was no different than the younger group (5.0 hours) (P = .4). The elderly exhibited a greater American Society of Anesthesiologist score, median body mass index (28.7 vs 25.1 kg/m2), and number of comorbidities (2.7 vs 0.9) (P < .001). There was no significant difference in either major or minor complications between the two groups. This suggests that with proper patient selection, abdominoplasty can be safely performed in the older age patient population. 2. © 2017 The American Society for Aesthetic Plastic Surgery, Inc.

Obesity is associated with poor surgical outcomes and disparity in access-to-care. There is a lack of quality data on the effect of body mass index (BMI) on perioperative outcomes. Accordingly, we sought to determine the procedure specific, independent-effect of BMI on 30-day perioperative outcomes in patients undergoing major surgery. Participants included individuals undergoing one of 16 major surgery (cardiovascular, orthopedic, oncologic; n = 141,802) recorded in the ACS-NSQIP (2005-2011). Outcomes evaluated included complications, blood transfusion, length-of-stay (LOS), re-intervention, readmission, and perioperative mortality. Multivariable-regression models assessed the independent-effect of BMI on outcomes. Nearly, 74 % of patients had a BMI disturbance; the majority being overweight (35.3 %) or obese (29.8 %). Morbidly obese patients constituted a small but significant proportion of the patients (5.7 %; n = 8067). In adjusted-analyses, morbidly obese patients had significantly increased odds of wound complications in 15 of the examined procedures, of renal complications after 6-procedures, of thromboembolism after 5-procedures, of pulmonary, septic and UTI complications after 2-procedures, and of cardiovascular complications after CABG. Conversely, obese/overweight patients, except for increased odds of wound complications after select procedures, had significantly decreased odds of perioperative mortality, prolonged-LOS and blood transfusion relative to normal BMI patients after 4, 8, and 9 of the examined procedures. The prevalence of BMI derangements in surgical patients is high. The effect of BMI on outcomes is procedure specific. Patients with BMI between 18.5 and 40-kg/m(2) at time of surgery fare equally well with regard to complications and mortality. However, morbidly obese patients are at-risk for postsurgical complications and targeted preoperative-optimization may improve outcomes and attenuate disparity in access-to-care.

The purpose of the present study was to evaluate antenatal depression screening employing two scales: the Postpartum Depression Screening Scale (PDSS) and Edinburgh Postnatal Depression Scale (EPDS) for the population of Chinese pregnant women with obstetric complications. A convenience sample of 842 Chinese pregnant women with complications participated in this study. The PDSS total score correlated strongly with the EPDS total score (r=0.652, p=0.000). Each tool performed extremely well for detecting major and major/minor depressions with PDSS resulting in a better psychometric performance than EPDS (p<0.01). If combined use, the recommended EPDS cut-off score was 8/9 for major depression, at which the sensitivity (71.6%) and specificity (87.6%) were the best, and the recommended PDSS cut-off score was 79/80 for major depression, along with its best sensitivity (86.4%) and specificity (100%). The study concluded that EPDS and PDSS appear to be reliable assessments for major and minor depression among the Chinese pregnant women with obstetric complications. Combined use of these tools should consider lower cutoff scores to reduce the misdiagnosis and improve the screening validity. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

A major vascular injury is the most feared complication of endoscopic sinus and skull base surgery. Risk factors for vascular injury are discussed, and an algorithm for management of a major vascular injury is presented. A team of surgeons (otolaryngology and neurosurgery) is important for identification and control of a major vascular injury applying basic principles of vascular control. A variety of techniques can be used to control a major injury, including coagulation, a muscle patch, sacrifice of the artery, and angiographic stenting. Immediate and close angiographic follow-up is critical to prevent and manage subsequent complications of vascular injury. Copyright © 2016 Elsevier Inc. All rights reserved.

The complications of otitis media (intra-cranial and extra-cranial) used to have a high morbidity and mortality in the pre-antibiotic era, but these are now relatively rare, mainly due to the use of antibiotics and the use of ventilation tubes, reducing the incidence of such complications significantly. Currently, an early suspicion of these complications is a major challenge for diagnosis and management. The cases of 5 patients (all male) are presented, who were diagnosed with complicated otitis media, 80% (4) with a mean age of 34.6 years (17-52). There was major comorbidity in 60% (3), with one patient with diabetes mellitus type 2, and two with chronic renal failure. There were 3 (60%) intra-cranial complications: one patient with thrombosis of the sigmoid sinus and a cerebellar abscess; another with a retroauricular and brain abscess, and a third with meningitis. Of the 2 (40%) extra-cranial complications: one patient had a Bezold abscess, and the other with a soft tissue abscess and petrositis. All patients were managed with surgery and antibiotic therapy, with 100% survival (5), and with no neurological sequelae. The clinical course of otitis media is usually short, limiting the infection process in the majority of patients due to the immune response and sensitivity of the microbe to the antibiotic used. However, a small number of patients (1-5%) may develop complications. Otitis media is a common disease in our country, complications are rare, but should be suspected when the picture is of torpid evolution with clinical worsening and manifestation of neurological signs.

Complications in hospitalized trauma patients are major causes of morbidity and mortality. The aims of this study were to identify the in-hospital trauma patients' complications and identify the risk factors for complications in this population. A retrospective analysis was conducted in a sample from a Brazilian hospital. The sample consisted of 407 patients, 194 (47.66%) of whom had records of complications. The most common complications were infections (41.80%). The risk factors related to the complications were age, length of hospital stay, external causes, and injury severity. The complications were frequent in this sample, and the risk for complications was characterized by multiple factors.

Benign prostatic hyperplasia (BPH) is a condition that occurs increasingly with age. The established gold standard treatment for BPH has been the electrocautery-based transurethral resection of the prostate (TURP). TURP, however, is associated with several complications and side effects. Therefore, there is an increasing interest in a number of emerging minimally invasive therapies as alterative treatment options. Laser therapy using the Greenlight laser is a promising alternative to the traditional TURP. Selective absorption by hemoglobin allows rapid, hemostatic vaporization of prostate tissue. Additional advantages include avoidance or minimization of complications such as intraoperative fluid absorption, and bleeding, retrograde ejaculation, impotence, and incontinence, as well as its use in treating high volume BPH. We review the use of the Greenlight laser in the treatment of BPH, when comparing complications and advantages in relation to TURP.

Postpartum hemorrhage (PPH) is a potentially life-threatening condition, which needs multidisciplinary management. Uterine atony represents up to 80 % of all causes of PPH. Transcatheter arterial embolization (TAE) has now a well-established role in the management of severe PPH. TAE allows stopping the bleeding in 90 % of women with severe PHH, obviating surgery. Pledgets of gelatin sponge as torpedoes are commonly used for safe TAE, and coils, glue, and microspheres have been primarily used in specific situations such as arterial rupture, pseudoaneurysm, and arteriovenous fistula. TAE is a minimally invasive procedure with a low rate of complications, which preserves future fertility.more » Knowledge of causes of PPH, potential risks, and limitations of TAE is essential for a timely decision, optimizing TAE, preventing irreversible complications, avoiding hysterectomy, and ultimately preserving fertility.« less

Abstract Atrioventricular groove rupture is a rare, albeit mortal, complication following mitral valve surgery. Avoidance is the best strategy but it cannot fully prevent the occurrence of this complication. Several repair techniques have been described with varying success rates; however, the rarity of the complication precludes consensus about the safest technique. Here we report two cases of posterior atrioventricular groove rupture. Both cases were diagnosed immediately after the cessation of cardiopulmonary bypass. Repair was performed successfully with a technique involving the use of biological glue. The postoperative course was uneventful for both of them. Both cases are well with normally functioning mitral prostheses; one with a follow-up time of 5.5 years and the other 10 months. We believe that the glue provides additional hemostasis and support to the repaired area. PMID:25870633

Hydrogel encircling bands were introduced in the early 1980s as a product that was superior to bands composed of silicone rubber or silicone sponge for the surgical treatment of retinal detachment. Late complications consisting of orbital swelling and diplopia requiring band removal began to be reported in the early 1990s. Pathologic studies of these expanded fragments of hydrogel material after removal showed in vivo hydrolysis with foreign body reaction and dystrophic calcification. We report the imaging findings in five patients in whom this late complication developed. Hydrogel fragmentation has a characteristic imaging appearance consisting of a circumferential orbital mass associated with rim enhancement. This appearance should prompt inquiries regarding previous scleral buckle procedures with hydrogel bands. Familiarity with this appearance will avoid misinterpretation and unwarranted biopsy before band removal.

The purpose of the study is to evaluate those cases of pterygium surgery with fibrin sealant that produced dehiscence of the graft, and then apply and evaluate the efficacy of a different surgical technique in an attempt eliminate this complication in previously identified cases of high risk. The first phase is a retrospective study of 42 cases of pterygium surgery. In the second phase, the variation in the surgical technique was prospectively used in 14 cases of pterygium surgery. Cases of recurrent pterygium, broad pterygium, and complicated surgery were identified as the groups with a risk of suffering dehiscence of the graft. With the variant applied surgery no dehiscence occurred when using the variation in surgical technique, with no added complications. Copyright © 2012 Sociedad Española de Oftalmología.

Background To immediate reconstruct ptosis breasts, we used polyglactin (Vicryl; Ethicon Inc., Somerville, NJ, USA) mesh as an inferolateral sling. However, Vicryl mesh is absorbable and losing function as a supporting structure. We doubt about the stability of the blood supply to the inferior part of the flap when it is in direct contact with inner implant. In this study, we examine the complications and the safety of the skin flap of this absorbable mesh sling (AMS) procedure. Methods The outcomes of 80 cases were examined, and the 1-year safety record of 40 cases was assessed. Complications were divided into minor complications, major complications requiring surgical intervention, and major complications requiring the reconstructive surgery to be halted. In addition, we examined the blood perfusion of the skin flap by dynamic infrared thermography (DIRT). Results Among 80 patients with AMS procedure, 73 breasts were reconstructed immediately and in one-stage. Complication outcomes are presented; there were 4 cases of minor flap necrosis (5%) and 4 of major complications resulting in surgical correction (5%). One patient required additional surgery, and the implant was moved into the musculocutaneous flap (1.3%). In 40 patients 1 year after surgery, DIRT showed significant decreased of blood perfusion in the ipsilateral inferior sites in comparison with the superior sites. Conclusions Blood perfusion was comparably insufficient in the inferior area of the reconstructed breast mound with AMS, where the pectoralis muscle could not be used to line the inside of the envelope. However, there were no severe flap complications due to ischemia. PMID:28210555

2011-02-01

Posterior operative approach has been the standard treatment for cervical compressive myelopathy, and axial pain after laminoplasty or laminectomy as a postoperative complication is now gradually receiving more and more attention. The objective of this study was to provide a systematic review of the current understanding of axial pain after cervical laminoplasty and laminectomy, and summarize clinical features, influence factors and preventive measures of axial pain after posterior decompressive surgery based on a review of literature published in the English language. Axial pain distributes over nuchal, periscapular and shoulder regions. Posterior surgery is not the major cause of axial pain, but axial pain can be worsened by the procedure. There are many clinical factors that influence postoperative axial pain such as age, preoperative axial pain, different surgical technique and postoperative management, but most of them are still controversial. Several surgical modifications have been innovated to reduce axial pain. Less invasive surgery, reconstruction of the extensor musculature, avoiding detachment of the semispinalis cervicis muscle and early removal of external immobilization have proved to be effective. Axial pain is under the influence of multiple factors, so comprehensive methods are required to reduce and avoid the postoperative axial pain. Because of methodological shortcomings in publications included in this systematic review, different results from different studies may be produced due to differences in study design, evaluation criteria, sample size, and incidence or severity of axial pain. More high-quality studies are necessary for drawing more reliable and convincing conclusions.

The goal of this study is to investigate the stigma of mental illness from the perspective of the persons directly affected by it. 210 patients with schizophrenia or major depression were questioned about anticipated and concrete stigmatization experiences, using a questionnaire especially developed for this study. Most of the patients expected negative reactions from the environment. Three quarters were convinced that their job application would be rejected when it became known that they are mentally ill. Almost two thirds felt apprehensive that others would avoid them due to their illness. There is hardly any difference between schizophrenia and depressive patients' assessment of stigmatization of mentally ill people. Concrete stigmatization experiences were most frequently reported in the domain of interpersonal interaction. Second comes the distorted picture of mentally ill people that is depicted in the media and experienced as hurtful by the patients. The obstacles to access social roles (partnership, work, etc.) perceived by the patients come third. Participants least frequently mentioned structural discrimination, i. e. disadvantages regarding psychiatric treatment or rehabilitation measures. Contrary to anticipated stigmatization, there are differences between the two diagnostic groups when it comes to concrete stigmatization experiences. Schizophrenia patients more frequently report that others would avoid contact with them and that the access to social roles was especially complicated for them. They also seemed to be more exposed to structural discrimination than depressive patients. Based on the results of this study, ways are discussed of how stigmatization and discrimination of mentally ill people can be reduced.
