Colorectal cancer is one of the most common types of cancer in Ukraine. Prognosis for patients with peritoneal carcinomatosis is unfavorable, and life expectancy is typically less than 6 months. Cytoreductive surgery was introduced as a new method of treating these patients to prolong their survival time.The objective of the research was to evaluate and compare the efficacy of cytoreductive surgery, chemotherapy and symptomatic treatment of patients with colorectal cancer and peritoneal carcinomatosis.Materials and methods. The research included 93 patients with colorectal cancer and peritoneal carcinomatosis. All patients were divided into 3 groups depending on the method of treatment being used after the detection of peritoneal carcinomatosis: Group I - cytoreductive surgery, Group II - palliative chemotherapy, Group III - symptomatic treatment. Cumulative overall survival in three groups was analyzed using the Kaplan-Meier method.Results. Statistically significant difference in overall survival was observed between patients treated with different methods. The median overall survival of patients of Group I (n=44) was 15.5 months; the median overall survival of patients of Group II (n=27) was 5.9 months; in patients of Group III (n=22) it was 3.1 months (p <0.0001). The analysis of patients’ survival in Group I depending on the application of palliative chemotherapy after cytoreductive surgery showed no significant difference in overall survival: 16.5 months with chemotherapy versus 14.2 months without chemotherapy (p = 0.12).Conclusions. Overall survival of patients with colorectal cancer and peritoneal carcinomatosis was higher when treated with cytoreductive surgery compared to palliative chemotherapy and symptomatic treatment. Palliative chemotherapy had no effect on survival after cytoreductive surgery for peritoneal carcinomatosis.

ObjectiveOvarian metastases occur in 3%–5% of patients with colorectal cancer. The role of oophorectomy in that setting continues to be debated. We aimed to assess the survival of women treated with metastasectomy for ovarian metastasis.MethodsRetrospective cohort study of patients in the California Cancer Registry (2000–2012) with stage IV colorectal cancer and ovarian metastases. Pathology other than adenocarcinoma was excluded. Adjusted Cox-proportional hazard analysis was applied to assess the risk of death.ResultsA total of 756 patients with synchronous ovarian metastases and 516 patients with metachronous ovarian metastases form the basis of this analysis. Median follow-up for the synchronous cohort was 21 months (IQR: 8–36). Median overall survival was 23 months (IQR: 10–42). Estimated 5-year survival reached 17% and 10-year survival was 8%. There was a significant difference in unadjusted survival between patients with solitary ovarian metastasis (median overall survival: 51 months) compared with those who had both ovarian and extraovarian metastases (20 months) (log-rank test, P<0.0001). For patients with solitary ovarian metastases, the 5- and 10-year survival was 46% and 31%, respectively. Among patients with synchronous ovarian metastases, longer unadjusted survival was observed after oophorectomy (median overall survival: 24 months) compared with no oophorectomy (18 months, log-rank P=0.01). For patients with metachronous diagnoses of colorectal cancer ovarian metastasis, the median disease-free survival was 19 months. The median survival after resection of metachronous ovarian metastases was 25 months, with the survival directly related to the disease-free interval until metastasis. For patients with resected metachronous ovarian metastases, the 5- and 10-year post-metastasectomy survival was 14% and 5%, respectively.ConclusionsPatients with colorectal cancer ovarian metastasis have favorable long-term survival. Survival rates are higher if the tumor is isolated to the ovary or if metachronous to the primary cancer.

14067 Background: Intraperitoneal hyperthermic chemotherapy (IPHC) combined with Cytoreductive surgery (CRS) is an effective approach in the management of peritoneal carcinomatosis. A controversy exists concerning the use of an open or closed technique of delivery of the hyperthermic chemotherapy. A retrospective study of a prospective data base was performed to compare these two techniques with respect to overall survival, disease-free survival, length of hospital stay (LOS), and incidence of complications. Methods: From 1998 to 2005, 64 patients underwent CRS and IPHC. Nineteen patients underwent open technique and forty-five underwent closed technique. The pathological diagnoses included appendiceal carcinoma (35), pseudomyxoma peritonei (10), ovarian carcinoma (7), colon carcinoma (6), mesothelioma (5), and sarcoma (1). Cox Proportional-Hazards Regression analysis was performed. Results: Overall 5- year survival and disease free survival was 46% and 22%, respectively. No significant difference in overall survival (p=0.58), disease-free survival (p=0.37), or incidence of complications (p=0.66) was found between the groups. Open technique patients had a significantly shorter LOS than closed with a mean of 8.7 vs. 11.4 days [p=0.01] and a median of 8 vs.11 days [p=0.002] (Kruskal-Wallis Rank Sum Test). Conclusions: The improved survival seen in patients undergoing CRS and IPHC is not dependent on the choice of technique of delivery of the hyperthermic chemotherapy No significant financial relationships to disclose.

Abstract Background The clinical significance of indeterminate pulmonary nodules (IPN) in patients with resectable pancreatic adenocarcinoma (PDAC) is unknown. The rate of detection on IPN has risen due to enhanced staging investigations to determine resectability. IPNs detected on preoperative imaging represent a clinical dilemma and complicate decision-making. Currently, there are no recommendations on the management of IPN. This review provides a comprehensive overview of the current knowledge on the natural history of IPN detected among patients with resectable PDAC. Methods A systematic review based on a search in Medline and Embase databases was performed. All clinical studies evaluating the significance of IPN in patients with resectable PDAC were included. PRISMA guidelines were followed. Results Five studies met the inclusion criteria. The total patient population was 761. The prevalence of IPN reported ranged from 18 to 71%. The median follow-up duration was 17 months. The median overall survival was 19 months. Patients with pre-operative IPN which subsequently progressed to clinically recognizable pulmonary metastases, ranged from 1.5 to 16%. Four studies found that there was no significant difference in median overall survival in patients with or without IPNs. Conclusion This is a first review on the significance of IPN in patients with resectable PDAC. The preoperative presence of IPN does not demonstrate an association with overall survival after surgery. The identification of IPN is a significant finding however it should not preclude patients with resectable PDAC from undergoing curative resection.

Objective This study aimed to assess whether cord blood carboxyhemoglobin (COHb) levels in jaundiced term neonates with and without a positive direct Coombs test (DCT) and in healthy controls could be used as a predictor of severe hyperbilirubinemia. The percentage of cord blood COHb should be higher among neonates with Coombs-positive ABO hemolytic disease than among those with Coombs-negative ABO incompatibility and higher than that of ABO-compatible control neonates. Study Design This cross-sectional descriptive study of 198 term neonates comprised three subgroups: group I featured 68 DCT-positive ABO-incompatible neonates (ABO + DCT), group II featured 60 DCT-negative ABO-incompatible neonates with hyperbilirubinemia (ABO–DCT), and group III featured 70 healthy controls. COHb was determined by an OSM3 hemoximeter. Results Group I differed from groups II and III for cord blood bilirubin, cord blood hemoglobin, and cord blood hematocrit. Groups I and II had higher mean total serum bilirubin (TSB) levels than group III, while there was no difference in the mean TSB levels between groups I and II. There was no significant difference between the COHb group means for groups I, II, and III (p = 0.98). The area under the receiver operating characteristic curve calculated for group I/group III and group II/group III were found to be 0.62 and 0.54, respectively. Conclusion COHb levels did not prove to be superior to the DCT for predicting the risk of developing severe hyperbilirubinemia in term neonates. Key Points

Objectives To compare the clinical outcomes of patients undergoing additional procedures in endoscopic endonasal dacryocystorhinostomy (End-DCR) surgery and discuss the factors affecting the success of End-DCR surgery in light of relevant literature. Methods The study included 155 patients who underwent End-DCR surgery in our clinic due to epiphora. This was a prospective randomized, single-blind, controlled trial. Group I (control) included 54 patients who did not undergo silicone stent insertion or silver nitrate application, group II included 51 patients who underwent silicone stent insertion only, and group III included 50 patients who underwent silver nitrate application only. Statistical analysis was performed on follow-up data regarding anatomic and functional success rates. Results Revision surgery was performed in 16 patients who developed persistent epiphora in the postoperative period, including 6 in group I, 7 in group II, and 3 in group III ( P = .4). The most common reason for revision surgery was stenosis of the neo-ostium ( n = 8), followed by granulation tissue formation ( n = 5) and synechia formation ( n = 3). Granuloma formation was the most common postoperative complication, and a significant difference was found among the groups with regard to granuloma formation ( P = .04). At postoperative month 12, the functional success rate was estimated to be 88%, 86%, and 94%, and the anatomic success rate was estimated to be 94%, 92%, and 96% in groups I, II, and III, respectively, with no significant difference, found among the 3 groups with regard to both rates ( P = .79 and P = .76, respectively). Conclusion The results indicated that stenting and silver nitrate application did not affect surgical success. Our preliminary results on silver nitrate cauterization showed that it is an effective, inexpensive, and practical method to reduce granulation formation in the postoperative period.

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.

Introduction: Congenital malformations (CM) are most common in newborns and infants in the first year of life and require surgical correction in the first hours, days, months of life. Surgical interventions in severely ill babies with malformations can lead to catabolic stress, circulatory and respiratory disorders, metabolism shifts, water-electrolyte, protein, and acid-base status disorders. This study aimed to compare acid-base status in newborns and infants with congenital surgical pathology under different types of combined anesthesia.  Materials and methods: This retrospective study included 150 newborns and infants with CM who required surgery. The patients were divided into three groups based on types of provided anesthesia: inhalation by Sevoran (sevoflurane) and regional anesthesia (group I); inhalation of Sevoran and intravenous anesthesia by Fentanyl (group II); and intravenous combination of Fentanyl and 20% Sodium Oxybutyrate (group III). The analysis included: acid-base status, peripheral oximetry, and the need for an oxygen mixture inhaled by the patient. Results In group I, there was a significant reduction in partial tension of CO2 and increased pH from the pre-surgical status, at the time of induction of anesthesia, during the most painful, traumatic stage, and after surgery compared to group II and III. Peripheral O2 saturation was not critically reduced at all stages of observation except in babies of group I compared to group III at the stage of induction of anesthesia (97.79 ± 2.45 vs. 98.79 ± 1.63, p = 0.0194) and at the most painful period of surgery (96.29 ± 3.47 vs. 98.10 ± 2.47, p = 0.0368). In group I, newborns and infants required higher oxygen concentrations in the inhalation mixture. There was a significant difference in FiO2 between groups I and III during the most painful stage of surgery (0.47 ± 0.29 and 0.33 ± 0.2, p = 0.0071), and immediately after surgery (0.34 ± 0, 19 and 0.26 ± 0.13, p = 0.0246). Conclusion: Among the newborns and infants with CM requiring surgical intervention and combined anesthesia, the most substantial acid-base status changes were observed in the group where anesthesia was provided by Sevoran (sevoflurane) and regional anesthesia (Group I).

Background: Pinopods concentrations in endometrial surface is a marker of implantation. Estradiol valerate (EV) was used to change the adverse effects of Clomiphene Citrate (CC) on the endometrium. Objective: The goal was to assess whether there is a significant difference in the endometrial pinopods concentrations and other parameters after adding EV and progesterone to higher doses of CC. Materials and Methods: In this prospective randomized clinical trial, a total of 30 women who did not respond to 100 mg of CC from February 2016 to June 2016 were evaluated. They were divided into three groups: group I) received 150 mg of CC alone, group II) CC with EV, and group III) CC plus progesterone. On day 21 of the menstrual cycle, endometrial biopsy, a blood sampling, and a scanning by electron microscopy were performed. Results: On day 21 of the menstrual cycle, there was no significant difference in the pinopods concentrations (p = 0.641) and serum estrogen levels (p = 0.276) between groups. However, the Serum progesterone levels in group I was higher than the other two groups (p = 0.007) in the same day. Conclusion: Since the addition of EV and progesterone to higher dosages of CC did not change the pinopods concentration and serum estrogen levels on day 21 of the menstrual cycle, and the serum progesterone levels was higher in CC alone group (i.e. group I) compared to other groups, it can be concluded that the anti-estrogenic effects of CC just appear on the endometrium and not on the plasma levels.
