Transcatheter Embolization for Ruptured Aneurysm of Pancreaticoduodenal Artery

Abstract; Visceral arterial aneurysms are rare and only 2% involve the pancreaticoduodenal artery (PDA). The etiologies of PDA aneurysms include congenital or atherosclerosis, celiac axis stenosis, pancreatitis, mycotic, trauma, or fibromuscular hyperplasia. If PDA aneurysm ruptures, it will result in fatal hemorrhage with high mortality rates. Although abdominal computed tomographic scan is a valuable examination, the selective angiography is the criterion standard to diagnose PDA aneurysm. Operative treatment can be invasive for patients with ruptured PDA aneurysms. Endovascular therapy with embolization or sent in selected patients is an alternative mandatory method. Keywords: Aneurysm; Computed tomography; Embolization; Pancreaticoduodenal artery Case Presentation: A 54-year-old man, with a history of chronic pancreatitis associated with hypertriglyceridemia, presented to our emergency department with a 10-day history of abdominal pain. Computed tomographic scan of angiography (CTA) demonstrated a rupturedaccular aneurysm of inferior pancreaticoduodenal artery (PDA) with peritoneal hemorrhage and digital subtraction angiography disclosed a ruptured saccular aneurysm of inferior PDA with extravasation (Figure 1). The transcatheter embolization with coil was carried out successfully. Discussion:Cases of visceral artery aneurysms are a rare clinical entity of vascular disease found incidentally in 0.1% to 2% of the general population and only 2% involve the PDA [1-3], The etiologies of PDA aneurysms include degeneration (atherosclerosis), hereditary diseases, inflammation (pancreatitis and cholecystitis), infection (abscess and mycotic), vasculitis, trauma (iatrogenic or penetrating injury), collagen vascular disease, segmental arterial mediolysis and malignancy [1,2,4]. The incidence of PDA aneurysm associated with degeneration and pancreatitis had reported to be 90% and 14%, respectively [5]. Many cases of ruptured PDA aneurysms were few than 10 mm in diameter. The size of PDA aneurysm could not be a predictor of its rupture and only male gender was associated with the risk of PDA aneurysm rupture [3-5]. If PDA aneurysm ruptured, it would result in fatal hemorrhage with high mortality rates and reach up to 100% if untreated.4 Although abdominal CTA was a valuable examination, the selective angiography was the criterion standard to diagnose PDA aneurysm[2,4]. If unstable hemodynamic, an elective open surgical treatment could be considered in patients with ruptured PDA aneurysms [5,6]. In the era of minimally invasive therapeutic approaches, endovascular therapy with embolization or sent in selected patients was an alternative mandatory method. The successful rate of endovascular therapy for ruptured PDA aneurysm with stable hemodynamics has reported to be 80% to 100%.

Decision-Making Quality in Parents Considering Adenotonsillectomy or Tympanostomy Tube Insertion for Their Children

ImportanceShared decision making is a process in which clinicians and patients make health care decisions in a collaborative manner using the most up-to-date evidence, while considering patient values and preferences. Shared decision making is thought to have a positive influence on the decision-making process in medicine.ObjectiveTo describe the level of decisional conflict and decisional regret experienced by parents considering surgery for their children and to determine relations among decisional conflict, decisional regret, and shared decision making.Design, Setting, and ParticipantsA prospective cohort study was conducted at an academic pediatric otolaryngology clinic. Participants included 126 parents of children younger than 6 years who underwent consultation for adenotonsillectomy or tympanostomy tube insertion.Main Outcomes and MeasuresParent participants completed the Shared Decision Making Questionnaire–Parent version, Decisional Conflict Scale (DCS), and Decisional Regret Scale (DRS). Surgeons completed the Shared Decision Making Questionnaire–Physician version.ResultsThis study included 126 parents; 102 women (mean [SD] age, 33.2 [5.1] years) and 24 men (mean [SD] age, 35.6 [6.3] years). Overall, 34 parents (26%) reported clinically significant decisional conflict. Only 1 parent experienced moderate to strong decisional regret; 28 parents (43.7%) had mild decisional regret. Both parent and physician ratings of shared decision making were significantly negatively correlated with total DCS scores. Parent SDM-Q-9 and total DCS scores were significantly negatively correlated (rs[118] = −0.582; P < .001). Similarly, physician SDM-Q-Doc and total DCS scores were also significantly negatively correlated (rs[118] = −0.221; P = .04). Only parent ratings of shared decision making were significantly negatively correlated with total DRS scores (rs[63] = −0.254; P = .045). Those parents with clinically significant decisional conflict had significantly higher DRS scores (P = .02).Conclusions and RelevanceMany parents experienced significant decisional conflict when making decisions about their child’s elective surgical treatment. Parents who perceived themselves as being more involved in the decision-making process reported less decisional conflict and decisional regret. Future research should explore the influence of decision quality on health outcomes and develop methods to improve shared decision making.

Mucocele of the appendix during pregnancy: What to do?

Abstract The term mucocele is simply defined as the macroscopic description of an appendix that is grossly distended by intraluminal accumulation of mucoid material. Its incidence ranges from 0.2% to 0.7% of all appendectomies and during pregnancy it is even less frequent. After a mucocele diagnosis, the selection of an adequate surgical method is, in general, very important. But during pregnancy it is an even more complicated decision because of the lack of experience and evidence on elective surgical treatments in pregnant women. We present a commentary based on a case of a low-grade appendiceal mucinous neoplasm of the appendix, found on an appendectomy specimen because of a mucocele in a second trimester pregnant woman.

Management and outcomes of vaginal bleeding and heavy menstrual bleeding in women of reproductive age on direct oral anti-factor Xa inhibitor therapy: a case series

Observational data and results from post-hoc analyses in clinical trials suggest that direct oral factor Xa inhibitors might increase menstrual bleeding intensity in women of reproductive age, but the extent of this effect is unknown. We aimed to investigate the management and outcomes of vaginal bleeding complications during therapy with direct oral factor Xa inhibitors in a case series of women of reproductive age. To identify individuals for inclusion in this case series, we searched two sources of prospectively collected data from women of reproductive age treated with direct oral factor Xa inhibitors: the non-interventional Dresden NOAC Registry (NCT01588119), which is based in the administrative district of Dresden (Saxony, Germany), and all locally archived data from phase 3 trials of direct oral factor Xa inhibitors done at University Hospital Carl Gustav Carus Dresden. Vaginal bleeding events were defined as any vaginal bleeding complications as reported by the patient. We collected data on type and dosage of anticoagulation; suspected or confirmed bleeding events, hospital admissions, and mortality; and pattern and management of vaginal bleeding events. For all cases of bleeding identified, we reviewed all available source data to identify examination results suggesting potential underlying anatomical causes of bleeding. We identified 178 women of reproductive age who received direct oral factor Xa inhibitor therapy, of whom 57 had vaginal bleeding events, including 50 who received rivaroxaban, six who received apixaban, and one who received edoxaban. These 57 women had 72 vaginal bleeding events, including 59 cases of heavy menstrual bleeding and 13 bleeding events unrelated to the menstrual cycle. 51 (86%) of these heavy menstrual bleeding events (two major bleeding events, 17 clinically relevant non-major bleeding events, 32 minor bleeding events) were treated conservatively (eg, change of oral hormone therapy or reduction, temporary interruption, or discontinuation of direct oral factor Xa inhibitor) and the remaining eight (14%) events (three major bleeding events and five clinically relevant non-major bleeding events) required elective surgical or interventional treatment (hysterectomy, curettage, ovary excision, or excision of ovarian cysts). Of the 57 women, 13 (23%) had a second bleeding event and two (4%) had a third event. Nine patients had underlying anatomical abnormalities; compared with patients without abnormalities, these patients had more intense bleeding, more had recurrent bleeding (five [56%] of nine patients with abnormalities vs eight [17%] of 48 patients without abnormalities), and more needed surgical treatment for bleeding (eight [89%] of nine vs zero of 48). Vaginal bleeding, particularly heavy menstrual bleeding, is a common complication in women of reproductive age on direct oral factor Xa inhibitor therapy. Most cases can be treated conservatively, but patients with severe or recurrent vaginal bleeding complications should be assessed for underlying anatomical abnormalities, which might require surgical or interventional treatment. Further data are needed to provide guidance on prevention and treatment of vaginal bleeding complications in this patient population. None.

Impact of octogenarians on surgical outcome in colorectal cancer

AimColorectal cancer's (CRC) incidence occupies the second place among malignant tumours in men and the third place in women. The aging of the population raises new questions on the management of CRC in octogenarian patients. The objective of this study was to assess the influence of age (≥80) on treatment and surgical outcome of colorectal cancer. MethodIn the period between October 1995 and April 2014, a total of 1397 patients underwent emergency and elective surgical interventions for CRC; the first group (Group-Older – GO) was composed of 291 patients 80 years or older (20.9%, of which 46.4% were male). The second group (Group-Younger – GY) included 1106 patients younger than 80 years (79,1%, 57.7% males). ResultsSignificant differences between the two groups were observed regarding sex (p = 0.001), number of comorbidities (p = 0.001), ASA classification (p < 0.001), emergency presentation (p < 0.001), site of tumor (p = 0.010), need of intraoperative blood transfusions (p < 0.001), 30-days mortality (p < 0.001), 90-days mortality (p < 0.001) and morbidity in accordance with Clavien-Dindo classification (p < 0.001). When combining both elective and emergency procedures, multivariate logistic regression analysis showed that advanced age (≥80 years old) was an independent predictor factor of 30-days mortality (p = 0.023, OR = 2.23) and morbidity (p = 0.088, OR = 1.31), while it was not predictive of 90-days mortality. When considering only elective colorectal surgery, octogenarian age was not found to be a predictive factor of 30-day and 90-day mortality, but predictive of postoperative morbidity. ConclusionOld age (≥80) does not represent a contraindication to CRC elective surgical treatment, in emergency procedures it is associated with an increased risk of postoperative morbidity and mortality.

Parental decision making in pediatric otoplasty: The role of shared decision making in parental decisional conflict and decisional regret.

To date, there has been little research on shared decision making and decisional outcomes in pediatric surgery. The objectives of this study were to describe the level of decisional conflict and decisional regret experienced by parents considering otoplasty for their children, and to determine if they are related to perceptions of shared decision making. Prospective cohort clinical study. Sixty-five consecutive parents of children who underwent surgical consultation for otoplasty were prospectively enrolled. Participants completed the Demographic Form, the Decisional Conflict Scale, and the Shared Decision-Making Questionnaire after the consultation visit. The consulting surgeons completed the physician version of the Shared Decision-Making Questionnaire. Six months after surgery, parents completed the Decisional Regret Scale. The median decisional conflict was 15.63; 21 (32.8%) parents scored 25 or above, a previously defined cutoff indicating clinically significant decisional conflict. Parent ratings of shared decision making and decisional conflict were significantly negatively correlated (P < 0.001); however, there was no significant correlation between physician ratings of shared decision making and parental decisional conflict. Significant decisional regret was reported in two (3.2%) participants. Decisional regret and parent and physician ratings of shared decision making were both significantly negatively correlated (P = 0.044 and P = 0.001, respectively). Decisional regret and decisional conflict scores were significantly positively correlated (P = 0.001). Parent and physician ratings of shared decision making were correlated (intraclass correlation = 0.625, P < 0.001). Many parents experienced significant decisional conflict when making decisions about their child's elective surgical treatment. Fewer parents experienced significant decisional regret after the procedure. Parents who perceived themselves as being more involved in the decision making process reported less decisional conflict and decisional regret. Parents and physicians had varied perceptions of the degree of shared decision making. Future research should develop interventions to increase parents' involvement in decision making and explore the influence of significant decisional conflict and decisional regret on health outcomes. 2b.

Surgical Treatment of Paget Disease of the Vulva: Prognostic Significance of Stromal Invasion and Surgical Margin Status.

The aim of the study was to evaluate the risk of recurrence according to the surgical margin status and the presence of invasion or of superficially invasive carcinoma in patients with extramammary Paget disease (EMPD) of the vulva, who underwent elective surgical treatment. We performed a retrospective analysis of 27 patients with first diagnosis of extramammary Paget disease of the vulva, who underwent primary and elective surgical treatment from January 1989 to December 2014. A p value of less than .05 was considered statistically significant. Multivariable logistic regression was performed to adjust for confounding factors. We observed invasive disease in 11 cases, with microinvasion in 8 of them. A positive surgical margin was found in 10 patients. During a median follow-up period of 79.5 months, 8 patients (29.6%) showed a first recurrence after a median (range) time of 4.9 (2.3-7.1) years. No significant differences were observed between patients with recurrence and patients without recurrence with respect to age, number of vulvar sectors involved, bilaterality and multifocality, presence of invasion or microinvasion, and surgical margin status. However, during the follow-up period, the presence of invasion was higher (67% vs 41%) in patients with recurrence compared with patients without recurrence. The rate of recurrence of the disease after therapy is high. Patients should be subjected to a close and long-term follow-up to identify those who must undergo further treatment, especially if they presented with an invasive or even microinvasive disease. A free margin of no greater than 1 to 2 cm might be the most appropriate surgical choice.

Surgical approach to a pleomorphic adenoma of the palate with undisturbed growth lasting for 20 years

ObjectivesIn this case report, a stepby- step description is provided of our approach to elective surgical treatment in a 44-year-old Caucasian man affected with a pleomorphic adenoma of the hard palate measuring over 3 cm in diameter and left to grow for 20 years. Materials and methodsAfter removal of the lesion, a conservative surgical strategy was adopted in our case and the wound was left open to heal by secondary intention. Results and conclusionsAt the 6-month follow-up, the patient showed good healing of the palatal mucosa, and improved speech, masticatory and swallowing functions.Our case was characterized by a very long history (over 20 years without any treatment) but with a benign clinical course that did not lead to damage of the palatal bone.

Suture Cruroplasty Versus Prosthetic Hiatal Herniorrhaphy for Large Hiatal Hernia: A Meta-analysis and Systematic Review of Randomized Controlled Trials.

The aim was to conduct a meta-analysis of randomized controlled trials (RCTs) comparing 2 methods of hiatal closure for large hiatal hernia and to evaluate their strengths and flaws. Prospective RCTs comparing suture cruroplasty versus prosthetic hiatal herniorrhaphy for large hiatal hernia were selected by searching PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane Central Register of Controlled Trials published between January 1991 and October 2014. The outcome variables analyzed included operating time, complications, recurrence of hiatal hernia or wrap migration, and reoperation. These outcomes were unanimously decided to be important because they influence the practical approach toward patient management. Random effects model was used to calculate the effect size of both dichotomous and continuous data. Heterogeneity among the outcome variables of these trials was determined by the Cochran's Q statistic and I index. The meta-analysis was prepared in accordance with Preferred Reporting of Systematic Reviews and Meta-Analyses guidelines. Four RCTs were analyzed totaling 406 patients (Suture = 186, Prosthesis = 220). For only 1 of the 4 outcomes, ie, reoperation rate (OR 3.73, 95% CI 1.18, 11.82, P = 0.03), the pooled effect size favored prosthetic hiatal herniorrhaphy over suture cruroplasty. For other outcomes, comparable effect sizes were noted for both groups which included recurrence of hiatal hernia or wrap migration (OR 2.01, 95% CI 0.92, 4.39, P = 0.07), operating time (SMD -0.46, 95% CI -1.16, -0.24, P = 0.19) and complication rates (OR 1.06, 95% CI 0.45, 2.50, P = 0.90). On the basis of our meta-analysis and its limitations, we believe that the prosthetic hiatal herniorrhaphy and suture cruroplasty produces comparable results for repair of large hiatal hernias. In the future, a number of issues need to be addressed to determine the clinical outcomes, safety, and effectiveness of these 2 methods for elective surgical treatment of large hiatal hernias. Presently, the use of prosthetic hiatal herniorrhaphy for large hiatal hernia cannot be endorsed routinely and the decision for the placement of mesh needs to be individualized based on the operative findings and the surgeon's recommendation.

The predictive value of multiple electrode platelet aggregometry for postoperative bleeding complications in patients undergoing coronary artery bypass graft surgery.

IntroductionPostoperative bleeding is one of the most serious complications of cardiac surgery and requires transfusion of blood or blood products. Acetylsalicylic acid (ASA) and clopidogrel (CLO) are the two most commonly used antiplatelet agents; when used in combination (i.e., as dual antiplatelet therapy [DAPT]), they exert a synergistic effect. Dual antiplatelet therapy, however, significantly increases the risk of postoperative bleeding. The effect of antiplatelet therapy can be monitored by platelet aggregation testing. One of the most commonly methods used for assessing platelet reactivity is multiple electrode aggregometry (MEA) which can be performed with the use of Multiplate analyzer. Although the method has long been used in interventional cardiology to assess the effect of antiplatelet therapy, it is not available at cardiac surgery departments as a standard diagnostic procedure. The aim of the study was to establish the frequency of bleeding complications following coronary artery bypass graft (CABG) surgery in patients on single antiplatelet therapy (SAPT) and patients on DAPT and to determine the usefulness of routine measurement of platelet responsiveness before CABG surgery in patients receiving antiplatelet therapy.Material and methodsA consecutive cohort of 200 patients referred for elective surgical treatment of stable coronary artery disease was enrolled (100 consecutive patients on SAPT [ASA 75 mg/day] and 100 consecutive patients on DAPT [ASA 75 mg/day + CLO 75 mg/day]). All subjects continued their antiplatelet therapy until the day before surgery. For each subject, platelet aggregation testing in the form of an ASPI test and an ADP test was performed on the Multiplate analyzer. Each subject underwent coronary artery bypass grafting surgery. For the primary and secondary endpoints in our study we adopted the definition provided in ‘Standardised Bleeding Definitions for Cardiovascular Clinical Trials: A Consensus Report from the Bleeding Academic Research Consortium’ (‘Circulation’, 2011) for BARC type 4 bleeding (i.e. CABG-related bleeding).ResultsAn ROC curve was constructed for the ASPI test and ADP test for a total of 200 patients. No significant correlations were demonstrated between the ASPI test results and either the primary endpoint or the secondary endpoints. A correlation was found between the ADP test results and the composite primary endpoint and each of the secondary endpoints. The primary endpoint of major postoperative bleeding occurred in 16 subjects. From the ROC curve, we established the optimal cut-off value for the ADP test of 26 U at sensitivity of 72%, specificity of 69%, positive predictive value of 69.90%, and negative predictive value of 71.13%.ConclusionsIn patients on antiplatelet therapy, an ADP test result of < 26 U is strongly predictive of serious bleeding complications after CABG surgery. The MEA ADP test allows to identify the group of patients at an increased risk of postoperative bleeding.

Recovery time for inflamed middle ear mucosa in chronic otitis media

Conclusion: The present study shows that 2–3 weeks after medical treatment the status of middle ear mucosa in draining ears is similar to that of dry ears for at least 3 months.Objective: To measure the time required for an inflamed middle ear mucosa to return into optimal state after appropriate medical treatment in chronic suppurative otitis media (CSOM). To assess optimal timing for elective surgical treatment of draining ears in uncomplicated CSOM.Methods: In this prospective study, the Eustachian tube (ET) mucociliary clearance time (MCT) was used as the method to demonstrate the status of middle ear mucosa. In group 1 (28 patients) ET-MCT was measured in ears that were free of drainage for at least 3 months. In Group 2 (21 patients), ET-MCT was measured in draining ears, who responded to 10–14 days medical treatment, at presentation, after 10 days and 1 month.Results: The ET-MCT was 8.63 ± 1.32 min in group 1 and 28.96 ± 8.19 min in group 2 at presentation; and the difference was statistically significant (p < 0.001). The ET-MCT was 14.76 ± 5.11 min after 10 days and 9.31 ± 2.33 min after 1 month in group 2. The ET-MCT was indifferent between groups 1 and 2 after 1 month (p = 0.235).

Patient-reported Outcomes After Conservative or Surgical Management of Recurrent and Chronic Complaints of Diverticulitis: Systematic Review and Meta-analysis

Patients with diverticulitis develop recurrences and chronic abdominal symptoms. Recurrent diverticulitis is seldom complicated, which has led to a conservative treatment approach. However, some studies suggest that surgical intervention reduces recurrence and chronic abdominal problems. We conducted a systematic review and meta-analysis of quality of life (QOL) and other patient-reported outcomes (PROs) after conservative vs surgical treatment of uncomplicated diverticulitis. We searched the CENTRAL, MEDLINE, EMBASE, and PsycInfo databases for randomized trials and cohort studies reporting on QOL or other PROs after conservative or operative treatment for uncomplicated diverticulitis from January 1990 through May 2014. Eight PROs were defined and graded according to their clinical relevance. Risk of bias was assessed by using the Cochrane Collaboration tool. Subgroup and sensitivity analyses were performed to test the robustness of the results. The review protocol was registered through PROSPERO (CRD42013005854). We analyzed data from 21 studies that comprised 1858 patients; all studies had a high risk of bias. There were no head-to-head comparisons of gastrointestinal symptoms or general QOL between elective surgical vs conservative treatment of recurrent diverticulitis. On the basis of Short-Form 36 scores, patients had higher QOL scores after elective laparoscopic resection (73.4; 95% confidence interval [CI], 65.7-81.1) than conservative treatment (58.1; 95% CI, 47.2-69.1). A lower proportion of patients had gastrointestinal symptoms after laparoscopic surgery (9%; 95% CI, 4%-14%) than conservative treatment (36%; 95% CI, 27%-45%) in all cohorts and in 1 trial comparing these treatments (odds ratio, 0.35; 95% CI, 0.16-0.7). The proportion of patients with chronic abdominal pain after elective laparoscopy was 11% (95% CI, 1%-21%) compared with 38% (95% CI, 19%-56%) after conservative treatment. On the basis of a systematic review and meta-analysis, patients have better QOL and fewer symptoms after laparoscopic surgery vs conservative treatment. However, studies of PROs for treatment of diverticulitis were of low quality.

A comparison of outcomes of emergent, urgent, and elective surgical treatment of diverticulitis

BackgroundThere is a controversy regarding the best urgent surgical treatment of colonic diverticulitis. We sought to compare outcomes of patients who underwent surgery for diverticulitis by the type of admission. MethodsThe National Surgical Quality Improvement Program databases were used to examine the clinical data of patients who underwent colorectal resection for diverticulitis during 2012 to 2013. Multivariate regression analysis was performed to identify outcomes of patients. ResultsWe sampled a total of 13,510 patients admitted for diverticulitis who underwent colorectal resection, of which 7.8% had emergent and 19.7% had urgent operation. Patients with perforation (adjusted odds ratio [AOR] 188.56, P < .01) and preoperative sepsis (AOR 28.17, P < .01) had significantly higher rates of emergent surgery. Patients who underwent emergent operation had higher mortality (AOR 4.08, P = .04) and morbidity (AOR 2.14, P < .01). Emergent operations had a significantly higher risk of anastomosis leakage compared with elective operation (AOR 3.92, P = .02). ConclusionsEmergent treatment of diverticulitis is associated with a high morbidity and mortality. In the setting of emergent treatment of diverticulitis, colonic anastomosis without a stoma has a high risk of anastomosis leakage.

Laparoscopic surgery of benign liver tumours

273 patients underwent elective surgical treatment for benign liver lesions at the 1st Surgical Department of Semmelweis University, Budapest, Hungary between 2004 and 2014. Laparoscopic (LAP) interventions were performed in 83 cases. Cyst fenestration in 52, and hepatic resection in 31 cases. LAP liver resections were set against to open surgery of paired group of patients with comparable demographic and clinical parameters. Data revealed that the operative time in LAP group (113.7 min) was significantly longer than that in the open surgery group (89.5 min). The average postoperative length of hospital stay was shorter after LAP surgery (5.8 vs 9.1 days). There was no postoperative complication in the LAP group, two wound infections and one biliary collection were treated by ultrasonic drainage in the open group. Three patients were given blood transfusion in the LAP, four in the open group. Operative mortality was zero, and no reoperation required. The surgical technique which is described in detail in the text enables safe resection of segments 7-8 which are difficult to approach. Our data support the safety and feasibility of laparoscopic liver resection after adequate preoperative investigations.

Quality and Safety of General Anesthesia with Propofol and Sevoflurane in Children Aged 1-14 Based on Laboratory Parameters.

Introduction:Knowledge of anatomic, physiological, biochemical and physical characteristics of children of all age groups, the existing illness and possible pathological response of the organism to the existing situation, require a pediatric anesthesiologist to participate in the preparation of a child for surgical treatment, to choose the best anesthesia technique and medications, and manipulative techniques to enable the scheduled surgical treatment with minimum anesthesia risks. The aim of this clinical study was to prove reliability and quality of propofol or sevoflurane general anesthesia in children in the age group of 1-14 years from the ASA I group and in the elective surgical treatments in duration of 60 minutes, based on preoperative and postoperative levels of laboratory findings (transaminases, blood sugar, urea and creatinine).Materials and methods:the study included 160 patients randomized in two groups based on different approaches: total intravenous anesthesia was used for the propofol group (n=80) (TIVA) and the inhalation technique was used for the sevoflurane group (n=80).Results:statistical evaluation of the obtained results indicates stability of laboratory findings in the immediate postoperative course (after 24 hours) in respect to the preoperative period. Based on the Mann Whitney test (P), preoperative and postoperative blood sugar levels in the sevoflurane vs. propofol group were P=0.152 vs. 0.021; creatinine levels P=0.113 vs. 0.325; urea levels P= 0.016 vs. 0.900; AST levels P=0,031 vs. 0,268 and ALT levels P=0.021 vs. 0.058. Level of significance was P<0.5.Conclusion:Analysis of the examined laboratory parameters show that propofol and sevoflurane provide full security and quality of general anesthesia in children age group 1-14 years, from the ASA I group. All analyzed laboratory levels in the postoperative course remained in their referential values in both groups of participants.

Immediate preoperative nutritional status of patients with colorectal cancer: a warning.

Weight loss and malnutrition are disorders observed in colorectal cancer patients. We sought to evaluate the immediate preoperative nutritional status of patients with colorectal cancer. This is a cross-sectional clinical study conducted at a single center. Sixty-six consecutive patients in preoperative for elective surgical treatment were studied. The clinical history, socio-demographic data and nutritional status of the patients were evaluated using Subjective Global Assessment and objective (anthropometry) methods. The primary outcome measures were nutritional status classification as nourished or malnourished and the relationship between nutritional status and socio-demographic and clinical features. Most of patients exhibited left colon tumors and disease stage II. According to the Subjective Global Assessment, 36.4% of patients were malnourished. Malnutrition ranged from 7.6% to 53% depending on the evaluation method used, with poor correlation to Subjective Global Assessment. The prevalence of malnutrition was significantly greater in females and non-married patients and in those with two or more symptoms of colorectal cancer. More than a third of patients in the immediate preoperative period for colorectal cancer exhibited malnutrition. Therefore, routine nutritional assessment is highly advisable so that appropriate measures may be taken to minimize the potential postoperative complications.

141IN - The Role of Surgery for M1 Breast Cancer

ABSTRACT M1 breast cancer is regarded as an incurable disease. Therefore, surgery has been considered as beneficial only for palliative purposes, like toilet mastectomy for ulceration, bleeding or pain. However, several recent studies show, that patients who have received elective surgery as a part of their treatment live longer than those with surgical treatment. The biological basis behind the phenomenon has been speculated. Surgery leads to decreased tumour burden, lower levels of circulating tumour cells and maybe beneficial immunological responses. On the other hand, majority of the studies reporting longer survival in operated patients are retrospective. Patients who have received surgical treatment have been younger, have received more systemic treatments, especially chemotherapy and anti-HER2 agents, have had fewer metastatic sites or asymptomatic metastases only. Therefore, the observed longer survival in operated patients may be just due to selection bias. Moreover, many of these studies suffer also other methodological shortcomings. A few randomized trials have been launched to clarify if surgery really prolongs survival in M1 breast cancer, including the Turkish MF 07-01 protocol, the Indian trial from Tata Memorial Centre, the Dutch SUBMIT trial and the Japanese JCOG1017 trial. The results from the two first mentioned trials were reported in SABCS 2013. In the Indian trial, surgery was not associated with survival benefit, neither in the entire study population of 350 patients nor in any of the evaluated subgroups. Neither the Turkish trial was able to show survival benefit after surgery in the entire study population (N = 278) during a median follow-up of 18 months. The authors also reported numerous subgroup analyses, suggesting possible survival benefit in younger patients, in patients with bone metastases only, especially in those with solitary bone metastasis. Patients with initial surgery and multiple liver or pulmonary metastases, in turn, did worse than those with systemic treatment only. However, these subgroup analyzes were unplanned and may therefore suffer from multiple testing. In conclusion, the results from the two reported randomized trials were mainly discouraging and do not indicate elective surgical treatment in patients with M1 breast cancer outside trials.

A two-year follow-up for Chinese patients with abdominal aortic aneurysm undergoing open/endovascular repair

Background A number of studies have demonstrated the rates of overall and aneurysm-related mortality and morbidity in Western populations. The cardiovascular risk factors influencing postoperative outcome have been also reported. Until recently, little has been known about the prognosis in this patient cohort in the Chinese population. We evaluated the independent predictors of mortality and morbidity in abdominal aortic aneurysm (AAA) patients undergoing elective surgical treatment and emphasized whether the coronary artery revascularization could have any effect on the overall mortality and morbidity in patients following the current guideline recommendation. Methods A total of 386 patients (174 women) undergoing surgery in Beijing Anzhen Hospital from January 2008 to June 2010 were enrolled (mean age (70.6±10.5) years). Kaplan-Meier curves were constructed to compare the mortality and morbidity of AAA patients with coronary artery revascularization and those without. A Cox proportional hazards model was constructed to identify clinical factors associated with two-year outcomes. The primary outcomes were death from any cause, the pre-specified morbidity was re-hospitalization for pulmonary conditions, congestive heart failure, angina, ischemic/hemorrhagic stroke. Results During the two-year follow-up, 34 patients died and 65 experienced re-hospitalization with pulmonary conditions, congestive heart failure, angina, or ischemic/hemorrhagic stroke. Kaplan-Meier survival analysis showed that the AAA patients with cardiac revascularization had no higher incidence of overall mortality and major morbidity than those without (log-rank test P=0.35 and P=0.40, respectively). Cox proportional hazards regression analysis showed that level of lowdensity lipoprotein (HR, 4.06; 95% CI: 1.19-18.7, P=0.027) and AAA size (HR, 2.18; 95% CI: 1.28-11.65, P=0.036) were independently associated with the incidence of overall mortality. Long-term use of angiotensin converting enzyme inhibitors, statins, AAA size and systolic blood pressure were independent predictors of the secondary pre-specified outcomes. Conclusions Coronary artery revascularization following the guideline recommendations did not increase the mortality and morbidity of Chinese with AAA who were undergoing repair. Absence of angiotensin converting enzyme inhibitors and statins, AAA size, and systolic blood pressure were powerful predictors of the clinical events.

The Risk of Surgical Treatment in Patients Aged 85+, with Special Consideration of Colorectal Cancer

The increase in prevalence of chronic diseases in old age is concomitant with increasing risk of neoplasms requiring surgical treatment. The aim of the study was to assess the indications, treatment outcomes, complications and mortality associated with surgical treatment of patients aged 85 or more, with special consideration of colorectal cancer. The retrospective analysis involved a group of 94 patents (x = 88.9) aged 85 or more and treated surgically in the years 2006-2011. The results were compared with a randomly selected control group of 91 patients aged 45-75 (x = 56,4) and treated surgically in the same period. Neoplastic diseases in the study group (85 ≥), compared with the control group (< 75), were a significantly more frequent indication for surgical treatment (p < 0.01). In the group of patients aged 85 or more, the most frequent indications for elective surgery were neoplasms of the skin and subcutaneous tissue (26.4%) and gastrointestinal neoplasms, mainly colorectal cancer (23.5%). Postoperative complications were significantly more frequent (p < 0.01) among patients aged 85 or more (n = 27; 34.8%) than in the younger group (n = 17; 18.7%). Postoperative mortality among patients undergoing emergency surgery was significantly higher (p < 0.05) in the senior group than in the group of younger patients. Surgical procedures in patients aged 85 or more are most frequently performed in the emergency setting, and their most common cause are neoplastic diseases. Emergency surgical treatment in patients aged 85 or more is associated with a significantly higher risk, compared with younger age groups, of developing multi-organ postoperative complications, usually leading to death. Elective surgical treatment in patients aged 85+ after appropriate preoperative preparation and in the group of younger patients shows similar early outcomes.
