ABSTRACT

Gestational diabetes (GDM) is considered to be the most common metabolic problem of pregnancy, which, if not recognized and treated on time, can lead to devastating effects on both the mother's health and the health of the fetus and the newborns. Many studies have revealed that the children born of GDM mothers or grandmothers have higher chances of developing diabetes type I or type II later in their life. Early identification of risk factors can help prevent the appearance of severe GDM and its complications witnessed both in the child and the mother. Obesity is one of the major risk factors that should not be ignored, and obese females should first undergo weight reduction plans in case of planned pregnancies. Other risk factors include a family history of DM arterial hypertension, significant weight gain during pregnancy, short sleep duration, women's exposure to stressful environments, changes in alpha and beta microbiota, and air pollution. Proper care should be provided to females of reproductive age both before and during pregnancy to avoid complications. Awareness programs for healthy lifestyles and diets, oral hygiene maintenance guides, and regular health check-ups can all be considered as a key to a healthy society. Expanding the analysis of gut microbiota in individuals at a heightened risk of GDM can hold particular value, especially during the preconception phase. The alterations in gut microbiota can serve as crucial factors in enhancing lifestyle modifications prior to conception. Further studies are required in this direction to decrease the prevalence of GDM, and efficient measures should be implemented before the consequences appear.

ABSTRACT

CONTEXT: Aromatase is a key enzyme in local estrogen production by androgen conversion, especially in women post-menopause. There have been controversies concerning aromatase localization in breast carcinomas and its association with current histopathological variables. MATERIAL AND METHODS: Using polyclonal antibody immunohistochemistry we assessed (by intensity and percentage scores) the immunolocalization of aromatase in 70 tissue samples, and described particularities within the molecular subtypes of breast cancer. RESULTS: Aromatase was found in all tissue compartments: tumor (95.7%), stroma (58.6%) and adipose tissue (94.3%). Aromatase expression in tumor cells correlated inversely with tumor grading (p=-0.361, p=0.027), and positively with estrogen receptor status (ER, p=0.143, p<0.001). Dividing the study group by intrinsic subtypes, a strongly inversely association between tumor aromatase and grading (p=-0.486, p<0.001), and between stromal aromatase and Ki67-index (p=-0.448, p=0.048) was observed in luminal A breast cancer. Tumor aromatase and ER percentage scores had stronger correlations in luminal B HER2 negative (p=0.632, p=0.002), and positive (p=0.324, p=0.026) tumors. In contrast, in triple negative tumors, a positive association stromal aromatase and Ki67 index (p=-0.359, p=0.007) was observed. CONCLUSION: Local aromatase was linked to better tumor differentiation and proliferation in luminal breast subtypes, and not in triple negative cases, suggesting a potential prognostic role of aromatase in breast carcinomas.

ABSTRACT

BACKGROUND: Risk benefit strategies in managing inflammatory bowel diseases (IBD) are dependent upon understanding the risks of uncontrolled inflammation vs those of treatments. Malignancy and mortality in IBD have been associated with disease-related inflammation and immune suppression, but data are limited due to their rare occurrence. AIM: To identify and describe the most common causes of mortality, types of cancer and previous or current therapy among children and young adults with paediatric-onset IBD. METHODS: Information on paediatric-onset IBD patients diagnosed with malignancy or mortality was prospectively collected via a survey in 25 countries over a 42-month period. Patients were included if death or malignancy occurred after IBD diagnosis but before the age of 26 years. RESULTS: In total, 60 patients were identified including 43 malignancies and 26 fatal cases (9 due to cancer). Main causes of fatality were malignancies (n = 9), IBD or IBD-therapy related nonmalignant causes (n = 10; including 5 infections), and suicides (n = 3). Three cases, all fatal, of hepatosplenic T-cell lymphoma were identified, all were biologic-naïve but thiopurine-exposed. No other haematological malignancies were fatal. The 6 other fatal cancer cases included 3 colorectal adenocarcinomas and 3 cholangiocarcinomas (CCAs). Primary sclerosing cholangitis (PSC) was present in 5 (56%) fatal cancers (1 colorectal carcinoma, 3 CCAs and 1 hepatosplenic T-cell lymphoma). CONCLUSIONS: We report the largest number of paediatric-onset IBD patients with cancer and/or fatal outcomes to date. Malignancies followed by infections were the major causes of mortality. We identified PSC as a significant risk factor for cancer-associated mortality. Disease-related adenocarcinomas were a commoner cause of death than lymphomas.

ABSTRACT

The paper presents the case of a male patient, hospitalized for acute abdomen due to perforated callous ulcer. Though the clinical appearance suggested a benign pathology, the histopathological exam of the resection piece showed multicentric early gastric carcinoma, signet ring cell type. At the patient's request, total gastrectomy was not performed, a conservative solution being chosen instead. Superior digestive endoscopy with biopsy and oncological dispensarization was performed one month after surgery, then at every 6 months. After 2 years of benign results, the histopathological exam revealed the presence of malign singlet ring cells in the bioptic specimen. Respecting the patient's option of preserving a good quality of life, subtotal gastrectomy with Pean type gastroenteroanastomosis was performed followed by postoperatory chemotherapy. Endoscopic and oncological follow-up were performed at every six months for another 3 years (up to present), and the evolution was favorable with no local or metastatic recurrence. Histopathological examination was of great help in the surgical management of this case, allowing a fortunate early diagnosis, a conservative surgical approach, and the preserving of a good quality of life.

ABSTRACT

Aim. To analyze the efficiency of laparoscopic cholecystectomy for the population aged 60 years and over admitted with acute cholecystitis, the clinical features and associated pathology presented by these patients and the impact of these factors on the choice of surgical technique. Materials and method. A retrospective study was carried out between February 2010 and February 2015, on patients aged 60 years and over, operated in emergency for acute cholecystitis in our clinic. All data were extracted from the registered medical documents and operatory protocols. Results. A total of 497 surgeries were performed for acute cholecystitis, of which 149 were patients aged 60 years and over (30%). Open surgery is much better represented in the population aged over 60 years (61.75% vs. 29.98%). One major cause is the associated pathology that increases the anesthetic risk and hampers a laparoscopic procedure. The conversion rate in the study group presented a higher percentage, but not more exaggerated than in the general population (6.71% vs. 4.63 %).Patients who underwent laparoscopic surgery had a faster recovery and required lower doses and shorter term pain medication, in contrast to conventional surgery (1,8 days vs. 5.7 days). Bile leak has been of reduced quantity, short-term and stopped spontaneously. Only one case needed reintervention, in which aberrant bile ducts that were clipped were found in the gallbladder bed, was operated by laparoscopy. Wound infections and swelling were also encountered more frequently in patients that underwent classic surgery (3.24%). Conclusions. Performing laparoscopic cholecystectomy, when possible, has produced very good results, reducing the average length of stay of patients and even decreasing the number of postoperative complications, thus allowing a faster reintegration of patients into society. The main concern was related to the associated pathology that increased the anesthetic risk.

ABSTRACT

Aim. The present study aimed to perform a medico-surgical comparative analysis of the 2 most widely used techniques: gastrostomy with peritoneal collar versus percutaneous endoscopic gastrostomy, based on the vast clinical experience in an Upper Digestive Surgery Clinic. Materials and method. A retrospective study was carried out between January 2010 and January 2015 on the patients admitted for a surgical solution for feeding. The indications, preoperative preparation, surgical techniques, and postoperative outcomes were analyzed. Results. Out of the 94 cases admitted for a surgical solution for feeding, 67 underwent gastrostomy with peritoneal collar (GPC) and in 27 cases percutaneous endoscopic gastrostomy (PEG) was performed. The indications for GPC were benign or malign causes of dysphagia, the most frequent being malign tumors of tongue, pharynx and larynx (47.76%), advanced inoperable esophageal or eso-cardiac cancers (26,86%), post-caustic esophageal stenosis (10.44%). PEG was performed in patients with functional difficulties of swallowing: sequelae of cerebral vascular accidents (44.44%), low Glasgow Coma Scale Score (29.62%) of different etiologies, Parkinson disease (18.51%) advanced dementia (7.4%), early nasopharyngeal cancer (2 cases). The intraoperatory and postoperatory complications were few and of minor importance in both techniques, but PEG allowed an immediate retake of alimentation (vs. at least 48 hours wait in GPC), with less gastric stasis, biliary reflux and aspiration related respiratory problems. Conclusions. Both techniques are easy and safe to perform, but an appropriate selection is required according to the cause of the swallowing difficulty. In cases with permeable digestive tube, PEG may be an excellent minimally invasive solution, but the costs and availability of the PEG kit and prehydrolyzed nutritive solution, as well as the co-existence of an upper digestive endoscopy service were limitations that had to be taken into account.

ABSTRACT

We present the case of a 52-year-old male patient, hospitalized on an emergency basis in the University Emergency Hospital in Bucharest, after being diagnosed with pneumoperitoneum acute abdomen, for which emergency surgery was mandatory. A 3,5-4 cm malignant gastric perforation, ascitis and peritoneal carcinomatosis were found. The histopathological exam revealed infiltrative mucinous gastric carcinoma with epiploic metastasis. Due to the lack of available gastric material, an atypical surgical solution was performed: gastric packing with epiploic material by means of transgastric traction. The solution proved to be successful for short-term recovery. The underlying condition was not focused on, the patient being directed to the Oncology Department. Acute gastric perforation is a rare complication of gastric cancer, and the association with gastric linitis is uncommon. This specific histopathological condition made the classical surgical repair techniques unsuitable for the presented case and an atypical solution had to be performed.

ABSTRACT

PURPOSE: To investigate the role of reference height inter-test variability upon the variability of the stereometric parameters. MATERIALS AND METHOD: 204 glaucomatous patients underwent a complete ophthalmological exam, including Heidelberg Retina Tomography 3 (HRT-3). The exclusion criteria were optic disc or retinal pathology that might interfere with the detection of glaucoma progression, TSD >30µm. 4 sets of data were taken during the HRT-3 exam for each patient. RESULTS: RH variability ranged between -198 and 187. Correlation analysis revealed a linear dependence between the inter-test variability of RH and stereometric parameters change. The most powerful correlations were observed for: RNFL Thickness (r=0.756, p<0.001), Rim Area (r=0.662, p<0.001), C/D Area Ratio (r=-0.663, p<0.001). The least correlated were Height Variation Contour (r=0.31) and Cup Shape Measure (r=0.07, p=0.3). When RH variability did not exceed 25µm, the correlations with stereometric parameters change were not statistically significant (for Rim Area, r=0.21, p>0.05, for C/D Area Ratio, r=-0.13, p=0.22, for RNFL Thickness r=0.06, p=0.52). CONCLUSIONS: For values >25µm, the variability of the RH is a major factor determining test/retest variability for RNFL Thickness, Rim Area, C/D Area, Rim Volume and Linear C/D. Inter-test variability of RH <25µm is an important criterion for the clinical relevance of stereometric parameters changes.

ABSTRACT

Children and adolescents with Crohn's disease (CD) present often with a more complicated disease course compared to adult patients. In addition, the potential impact of CD on growth, pubertal and emotional development of patients underlines the need for a specific management strategy of pediatric-onset CD. To develop the first evidenced based and consensus driven guidelines for pediatric-onset CD an expert panel of 33 IBD specialists was formed after an open call within the European Crohn's and Colitis Organisation and the European Society of Pediatric Gastroenterolog, Hepatology and Nutrition. The aim was to base on a thorough review of existing evidence a state of the art guidance on the medical treatment and long term management of children and adolescents with CD, with individualized treatment algorithms based on a benefit-risk analysis according to different clinical scenarios. In children and adolescents who did not have finished their growth, exclusive enteral nutrition (EEN) is the induction therapy of first choice due to its excellent safety profile, preferable over corticosteroids, which are equipotential to induce remission. The majority of patients with pediatric-onset CD require immunomodulator based maintenance therapy. The experts discuss several factors potentially predictive for poor disease outcome (such as severe perianal fistulizing disease, severe stricturing/penetrating disease, severe growth retardation, panenteric disease, persistent severe disease despite adequate induction therapy), which may incite to an anti-TNF-based top down approach. These guidelines are intended to give practical (whenever possible evidence-based) answers to (pediatric) gastroenterologists who take care of children and adolescents with CD; they are not meant to be a rule or legal standard, since many different clinical scenario exist requiring treatment strategies not covered by or different from these guidelines.

ABSTRACT

AIM: The paper presents the surgical solving of an oesophageal stenosis, using a device of pneumatic dilatation with trans-gastrostomal approach, in a patient with multiple disabling handicaps, secondary severe malnutrition and previously diagnosed with scleroderma. MATERIALS AND METHOD: The patient was admitted with severe cachexia (37 kg, 170 cm), characteristic byzantine face with microstomy, distal phalanges resorption in both superior limbs and complete dysphagia, with limitation of mouth opening.The Barium swallow test revealed distal oesophageal stenosis,with an important dilation of the oesophagus above. RESULTS: A gastrostoma was placed to allow nutrition (Gavriliu procedure), under general anaesthesia with trans-tracheostomal intubation. After 3 years, with her metabolic status improved(59 kg), the patient returned to our clinic asking for a solution for natural feeding. The technical difficulties in solving this case were determined by the limited mouth opening, which made anterograde oro-oesophageal balloon dilatation or bougienage impossible, as well as oro-tracheal intubation.Making use of the presence of the gastrostomal orifice,knowing von Hacker's mechanical dilation procedure and using the metallic Key Med kit with balls offered the possibility of the tactics and strategy of guiding a metallic guidewire introduced via the gastrostoma, then trans-stenotic and pulled out through the oral orifice. A modified Foley catheter (personal procedure) was attached to the initial catheter. The trans-stenotic retrograde traction of the Foley balloon was the pneumatic dilator factor that later allowed easy dilatation with the metallic dilator of the Key Med, to the maximum size. The follow-up showed good results, the patient returned to natural nutrition. CONCLUSIONS: The device of oesophageal pneumatic dilatation allows, using the presented surgical technique, a gentle plasty done under radiological supervision and lowers the frequency of accidents. The dilation permits the following use of Key Med kit. The novelty consists in adapting a well-known technique to a new patented device of pneumatic dilation with bidirectional approach under radiological control, for solving this atypical case.

ABSTRACT

PURPOSE: The orphan, membrane-bound estrogen receptor (GPER) is expressed at high levels in a large fraction of breast cancer patients, and its expression is favorable for patients' survival. We investigated the role of GPER as a potential tumor suppressor in MCF-7 and SK-BR-3 breast cancer cells. METHODS: The effect of GPER agonist G-1 in cell culture was used to determine whether GPER inhibit cell growth. The methylation status of GPER promoter was investigated by methylation-specific PCR. RESULTS: GPER-specific agonist G-1 inhibited breast cancer cell proliferation in concentration-dependent manner via induction of the cell cycle arrest in M-phase, enhanced phosphorylation of histone 3 and cell apoptosis. Analysis of the methylation status of the GPER promoter in MCF-7 and SK-BR-3 cells revealed that GPER expression is regulated by epigenetic mechanisms and GPER expression is inactivated by promoter methylation. Overall, our results are consistent with our recent findings in triple-negative breast cancer cells, and the cell surface expression of GPER makes it an excellent potential therapeutic target for non-triple-negative breast cancer.

ABSTRACT

Invasive lobular carcinomas (ILC) show better clinical behaviour compared with other histological types, but significantly lower pathological complete response (pCR) rates after neoadjuvant chemotherapy (NACT). We investigated whether factors influencing pCR rate in ILC after NACT can be identified and whether clinical outcome is different. 9,020 breast cancer patients from nine German neoadjuvant trials with known histological type were pooled. 11.7 % of tumours were ILC. Endpoints were: pCR rate, surgery type and survival. ILC was associated with older age, larger tumour size, lymph node negativity, lower grade and positive hormone-receptor-status (HR). Patients with ILC achieved a significantly lower pCR rate compared with non-ILC patients (6.2 vs. 17.4 %, P < 0.001). The pCR rate was 4.2 % in ILC/HR+/G1-2, 7.0 % in ILC with either HR- or G3, and 17.8 % in ILC/HR-/G3. Mastectomy rate was higher in ILC compared with non-ILC patients irrespective of response to NACT (pCR: 27.4 vs. 16.6 %, P = 0.037 and non-pCR: 41.8 % vs. 31.5 %, P < 0.0001). Age and HR independently predicted pCR in ILC. In ILC patients, pCR did not predict distant disease free (DDFS) and loco-regional disease free survival (LRFS), but overall survival (OS). Non-pCR patients with ILC had significantly better DDFS (P = 0.018), LRFS (P < 0.0001) and OS (P = 0.044) compared with non-ILC patients. Patients with ILC had a low chance of obtaining a pCR and this is not well correlated with further outcome. The mastectomy rate was considerably high in ILC patients even after obtaining a pCR. We, therefore, suggest to offer NACT mainly to ILC patients with HR-negative tumours.

ABSTRACT

BACKGROUND: Minimally invasive transforaminal lumbar interbody fusion (MI TLIF) is very popular in the United States.Two techniques are commonly used, based on either tubular or pedicle-screw-based retraction. MATERIALS AND METHODS: Sixty patients underwent MI TLIF between 2009 and 2012, using the tubular technique (43 patients) or screw-based-retractor technique (17 patients).Perioperative parameters and 1-year outcomes were reviewed. RESULTS: For the tubular technique, the average operative time,blood loss, and hospital stay were 189 min, 170 ml, and 3.37 days, respectively. The visual analog scale (VAS) score improved from 9.7 preoperatively to 2.6 at 1-year postoperatively. There were two incidental durotomies, none resulting in a CSF leak.There was one re-intervention for removal of a misplaced pedicle screw. For the screw-based-retractor technique, the average operative time, blood loss, and hospital stay were 223 min, 257 ml, and 3.29 days, respectively. VAS improved from 9.4 to 1.9. One patient who had an incidental durotomy developed a postoperative compressive hematoma with resultant cauda equina syndrome requiring re-intervention.There were no re-interventions for revision of instrumentation.Seven patients were lost at the 1-year visit. The fusion rate at 1-year was 100%. CONCLUSION: Both techniques can be used with good results,but each technique offers distinct advantages and challenges that can be tailored to individual patients.

ABSTRACT

PURPOSE: to investigate the sensitivity and specificity of the stereometric parameters change analysis vs. Topographic Change Analysis in early detection of glaucoma progression. METHODS: 81 patients with POAG were monitored for 4 years (GAT monthly, SAP at every 6 months, optic disc photographs and HRT3 yearly). The exclusion criteria were other optic disc or retinal pathology; topographic standard deviation (TSD>30; inter-test variation of reference height>25 µm. The criterion for structural progression was the following: at least 20 adjacent super-pixels with a clinically significant decrease in height (>5%). RESULTS: 16 patients of the total 81 presented structural progression on TCA. The most useful stereometric parameters for the early detection of glaucoma progression were the following: Rim Area change (sensitivity 100%, specificity 74.2% for a "cut-off " value of -0.05), C/D Area change (sensitivity 85.7%, specificity 71.5% for a "cut off " value of 0.02), C/D linear change (sensitivity 85.7%, specificity 71.5% for a "cut-off " value of 0.02), Rim Volume change (sensitivity 71.4%, specificity 88.8% for a "cut-off " value of -0.04). RNFL Thickness change (<0) was highly sensitive (82%), but less specific for glaucoma progression (45,2%). Changes of the other stereometric parameters have a limited diagnostic value for the early detection of glaucoma progression. CONCLUSION: TCA is a valuable tool for the assessment of the structural progression in glaucoma patients and its inter-test variability is low. On long-term, the quantitative analysis according to stereometric parameters change is also very important. The most relevant parameters to detect progression are RA, C/D Area, Linear C/D and RV.

ABSTRACT

UNLABELLED: The aim of this study is to analyze the infection risk through spatter and aerosolization during scaling and to create a prediction model of the total number of hemolytic bacteria. MATERIAL AND METHODS: Air samples were collected prior to patient's arrival and spatter and aerosol samples were collected during scaling procedure in 80 patients of 4 different dental clinics. The dentists calculated DI, CI, DMFT. Only patients with CI > = 1 were included. The bacteriological results (CFU/m3) were correlated with clinical indicators. Patients were divided into 2 groups: one that rinse with sterile water and the other with chlohexidine mouth rinse 0.1%. RESULTS AND CONCLUSIONS: Medium size effect positive correlations were found between the number of decayed teeth and the total number of bacteria and the total number of hemolytic bacteria that grew on plate attached to the dentist's mask. The mean number of bacteria and the mean number of hemolytic bacteria that grew on plate attached to the dentist's mask were significantly lower in the group that rinse with chlorhexidine 0.1%, when compared to the group that rinsed with sterile water. When controlling for the total number of bacteria and the total number of hemolytic bacteria from air sampling, the total number of hemolytic bacteria that grew on the plate attached to the dentist's mask can be predicted by CI, group membership and DMFT score.

ABSTRACT

PURPOSE: This paper presents an analysis of surgical treatment costs for left colostomy, aiming to calculate a medium cost per procedure and to identify the means to maximize the economic management of this type of surgicale procedure. MATERIALS AND METHOD: A retrospective study was conducted on a group of 8 patients hospitalized in the 4th Surgery Department,Emergency University Hospital Bucharest, during the year 2012 for left colic neoplasms with obstruction signs that were operated on with a left colostomy. The followed parameters in the studied group of patients were represented by medical expenses, divided in: preoperative, intra-operative and immediate postoperative (postop. hospitalization). RESULTS: Two major types of colostomy were performed: left loop colostomy with intact tumour for 6 patients and left end colostomy and tumour resection (Hartmann's procedure) for 2 patients. The medium cost of this type of surgical intervention was 4396.807 RON, representing 1068.742 euro. Statistic data analysis didn't reveal average costs to vary with the type of procedure. The age of the study subjects was between 49 and 88, with an average of 61 years, without it being possible to establish a correlation between patient age and the level of medical spendings. CONCLUSIONS: Reducing the costs involved by left colostomy can be efficiently done by decreasing the number of days of hospitalisation in the following ways: preoperative preparation and assessment of the subject in an outpatient regimen; the accuracy of the surgical procedure with the decrease of early postoperative complications and antibiotherapy- the second major cause of increased postoperative costs.

ABSTRACT

BACKGROUND: Intramedullary hemangioblastomas are rare benign tumors, occurring sporadically or in von Hippel- Lindau disease. METHODS: We describe our local surgical experience with intramedullary hemangioblastomas. Clinical, imaging and surgical data from five consecutive hemangioblastoma cases identified from a series of 59 patients with intramedullary tumors treated between 2003-2009 are reviewed. RESULTS: The mean age of the patients was 39.6 years (range 21- 56). All of them were symptomatic and two patients had von Hippel-Lindau disease with associated posterior fossa hemangioblastomas. All tumors were preoperatively diagnosed as hemangioblastomas based on magnetic resonance findings. All patients underwent surgery with complete removal of the tumor in 4 cases and a partial removal in a case with extension towards the anterior part of the cord. Good neurological outcome was noted in four cases while in the fifth, complicated with a significant intraoperative hemorrhage, a fully reversible aggravation of neurological status occurred. CONCLUSIONS: Spinal cord hemangioblastomas are surgically curable tumors. Microsurgical complete resection is the standard of care and can be performed with good neurological outcome in most of the cases. Ventral tumor location and important intraoperative bleeding are associated with less optimal outcome.

ABSTRACT

INTRODUCTION: Postoperative adhesions after abdominal or pelvic surgery remain an important clinical problem causing infertility, pain and bowel obstruction. Their prevention and treatment remains poorly understood and inadequate. The formation of adhesions is caused by the organization of a fibrin matrix, an organization that takes place during the coagulation process when there is suppression of fibrinolysis. METHODS: In this study peritoneal tissue and peritoneal fluid from two groups of patients were sampled and analysed. The first group comprised of 12 patients undergoing abdominal surgery for an acute abdomen during which known peritoneal factors of aggression (trauma, chemical, bacterial) were present which are known to increase the propensity for peritoneal adhesion formation. A second group consisting of 6 patients undergoing surgery in the absence of these peritoneal aggression factors acted as a reference control group. Each patient had peritoneal tissue sampled at the time of surgery and analysed for levels of gene expression of tissue plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1). Patients also had peritoneal drain fluid collected postoperatively and analysed for quantities of fibrin degradation products (FDPs) and fibrinogen. RESULTS: The aim of this study was to evaluate the role of PAI-1 and tPA genes at peritoneal tissue level. Peritoneal tissue was obtained during surgery and the variation of expression of PAI-1 and tPA genes was quantified. The obtained results highlighted an increase of expression in PAI-1 gene and decrease of expression in tPA gene in patients with increased factors of peritoneal aggression compared to patients without, indicating a decreased fibrinolytic potential in patients with increased peritoneal adhesion propensity. Increased factors of peritoneal aggression also resulted in increased levels of FDPs and fibrinogen in peritoneal exudates.

ABSTRACT

AIM: Surgical procedures with curative or palliative intention in colo-rectal neoplasm in subjects aged over 80 represent a surgical challenge due to the issue they raise: benefits versus increased morbidity. In Romania, according to demographic predictions, the population over the age of 65 will double in the next half century. This, correlated with the increased incidence of colo-rectal cancer in subjects pertaining to the 60- 69 age period and higher, determined us to identify the factors that can influence the occurrence of complications and post-surgery deaths in subjects over 80 years of age that were operated on for colo-rectal cancer. METHODS: This paper includes a retrospective analysis of patients aged over 80, diagnosed and treated for colo-rectal cancer in the 4th Surgery Department of the University Emergency Hospital in Bucharest, in the period 2000 - 2011, following the type of surgery, morbidity and postoperative mortality. Out of a total of 297 cases of patients operated on for colo-rectal cancer, 36 were identified with the age over 80, age average being 83 years (80-91). RESULTS: Out of the total 36 patients aged over 80 years, 22 were subject to surgical procedures with curative intention (in 16 of these subjects a right hemicolectomy was performed and in 6 a left hemicolectomy), the remaining 14 subjects receiving palliative surgical treatment. The factors that negatively influenced post-surgery evolution were diabetes, pre-existing cardiac pathology, evolutionary stage of cancer and the urgency character. In the group with resections, we found a 27.2% (6 cases) morbidity rate and a 18.2% (4 cases) mortality rate. In patients undergoing palliative surgery, the morbidity rate was 28.5% (4 cases) with a mortality rate of 14.3% (2 cases). CONCLUSIONS: Between the 2 groups of patients postoperative morbidity and mortality appeared to be equal. Most often, they were caused by pre-existing cardio-pulmonary pathology and by the urgency character of the surgery, that did not allow a proper rebalancing, and in a lesser extent by the type of surgery. During those 12 years, the percentage of patients aged over 80 years diagnosed annually with colorectal cancer remained constant. Despite advanced age and associated comorbidities, we consider the postoperative evolution to be satisfactory, although postoperative morbidity and mortality were higher than in the general population, according to the literature. Preoperative compensation of associated comorbidities, a surgical procedure performed by experienced teams, together with the ensuring of adequate intensive therapies are required to reduce postoperative risks.
