A Post-International Gastrointestinal Cancers' Conference (IGICC) Position Statements.

Hepatocellular carcinoma (HCC), the most prevalent liver tumor, is usually linked with chronic liver diseases, particularly cirrhosis. As per the 2020 statistics, this cancer ranks 6th in the list of most common cancers worldwide and is the third primary source of cancer-related deaths. Asia holds the record for the highest occurrence of HCC. HCC is found three times more frequently in men than in women. The primary risk factors for HCC include chronic viral infections, excessive alcohol intake, steatotic liver disease conditions, as well as genetic and family predispositions. Roughly 40-50% of patients are identified in the late stages of the disease. Recently, there have been significant advancements in the treatment methods for advanced HCC. The selection of treatment for HCC hinges on the stage of the disease and the patient's medical status. Factors such as pre-existing liver conditions, etiology, portal hypertension, and portal vein thrombosis need critical evaluation, monitoring, and appropriate treatment. Depending on the patient and the characteristics of the disease, liver resection, ablation, or transplantation may be deemed potentially curative. For inoperable lesions, arterially directed therapy might be an option, or systemic treatment might be deemed more suitable. In specific cases, the recommendation might extend to external beam radiation therapy. For all individuals, a comprehensive, multidisciplinary approach should be adopted when considering HCC treatment options. The main treatment strategies for advanced HCC patients are typically combination treatments such as immunotherapy and anti-VEGFR inhibitor, or a combination of immunotherapy and immunotherapy where appropriate, as a first-line treatment. Furthermore, some TKIs and immune checkpoint inhibitors may be used as single agents in cases where patients are not fit for the combination therapies. As second-line treatments, some treatment agents have been reported and can be considered.

Effectiveness of metformin for the reversal of cold-ischemia-induced damage in hepatosteatosis.

BACKGROUND: Primary dysfunction and rejection are more common in donor liver tissues with steatosis. AMP-activated protein kinase (AMPK) assumes organ-protective functions during ischemia. Metformin was used for the activation of AMPK in hepatocytes. The aim of this study is to investigate the effectiveness of metformin administration for the reversal of cold-ischemia-induced damage in hepatosteatosis. MATERIAL AND METHODS: Seven-week-old C7BL56 male-mice (n = 109) were separated into four groups depending on diet type and metformin use. A specific diet model was followed for 10 weeks to induce hepatosteatosis. A group of the animals was administered with metformin for the last four weeks via oral gavage. After resection, the liver tissues were perfused and kept for 0-6-12-24 h in the UW solution. Histopathological examinations were performed, and Western blot was utilized to analyze p-AMPK and AMPK expression levels. RESULTS: Hepatosteatosis decreased significantly with metformin. The steatotic liver group had more prominent pericentral inflammation, necrosis as well as showing a decreased and more delayed AMPK response than the non-fat group. All these alterations could be corrected using metformin. CONCLUSION: Metformin can increase the resistance of livers with hepatosteatosis to cold-ischemia-induced damage, which in turn may pave the way for successful transplantation of fatty living-donor livers.

Assessing the Potential Apoptotic Effects of Different Hydatid Cyst Fluids on Human Healthy Hepatocytes and Hepatocellular Carcinoma Cells.

Cystic Echinococcosis (CE) is a zoonotic infection caused by the larval form of Echinococcus granulosus in humans. Emerging evidence suggests an intriguing inverse association between E. granulosus infection and the occurrence of cancer. This study aimed to investigate the influence of diverse host-derived hydatid cyst fluids (HCF) with distinct genotypes on human liver hepatocytes (HC) and hepatocellular carcinoma cells (HepG2). Specifically, we examined their effects on cell proliferation, apoptosis sensitivity (BAX/BCL-2), apoptosis-related p53 expression, and the expression of cancer-related microRNA (hsa-miR-181b-3p). Cell proliferation assays, real-time PCR, and ELISA studies were conducted to evaluate potential anti-cancer properties. The findings revealed that animal-origin HCF (G1(A)) induced direct cell death by augmenting the susceptibility of HepG2 cells to apoptosis. Treatment with both G1(A) and G1(H) HCF sensitized HepG2 and HC cell lines to apoptosis by modulating the BAX/BCL-2 ratio, accompanied by upregulation of the p53 gene. Additionally, G1(A) HCF and human-derived HCFs (G1(H), G7(H)) reduced the expression of miR-181b-3p in HepG2 cells. Consequently, this study demonstrates the potential anti-cancer effect of HCF in HepG2 cells and provides the first comparative assessment of HCFs from human and animal sources with diverse genotypes, offering novel insights into this field.

Changing trends in the etiology of liver transplantation in Turkiye: A multicenter study.

Background and Aim: This study aimed to identify the indications for liver transplantation (LT) based on underlying etiology and to characterize the patients who underwent LT. Materials and Methods: We conducted a multicenter cross-sectional observational study across 11 tertiary centers in Turkiye from 2010 to 2020. The study included 5,080 adult patients. Results: The mean age of patients was 50.3±15.2 years, with a predominance of female patients (70%). Chronic viral hepatitis (46%) was the leading etiological factor, with Hepatitis B virus infection at 35%, followed by cryptogenic cirrhosis (24%), Hepatitis C virus infection (8%), and alcohol-related liver disease (ALD) (6%). Post-2015, there was a significant increase in both the number of liver transplants and the proportion of living donor liver transplants (p<0.001). A comparative analysis of patient characteristics before and after 2015 showed a significant decline in viral hepatitis-related LT (p<0.001), whereas fatty liver disease-related LT significantly increased (p<0.001). Conclusion: Chronic viral hepatitis continues to be the primary indication for LT in Turkiye. However, the proportions of non-alcoholic fatty liver disease (NAFLD) and ALD-related LT have seen an upward trend over the years.

Comparison of Educational and Academic Quality of Laparoscopic Distal Pancreatectomy Videos on WebSurg® and YouTube® Platforms.

BACKGROUND: The aim of this study was to compare the educational and academic quality of laparoscopic distal pancreatectomy (LDP) videos on YouTube® and WebSurg® platforms. MATERIAL AND METHODS: YouTube and WebSurg platforms were searched with the keyword "laparoscopic distal pancreatectomy". According to the exclusion criteria, 12 videos were found on WebSurg. To ensure a 1:1 ratio, the first 12 videos that met the criteria on YouTube were also analyzed. Journal of American Medical Association (JAMA) benchmark criteria were used to evaluate the reliability of the videos. The non-educational quality of the videos was calculated using the Global Quality Score (GQS), the educational and academic quality of videos was calculated using Laparoscopic Distal Pancreatectomy-specific score (LDP-SS) and Laparoscopic Surgery Video Educational Guidelines scoring system (LAP-VEGaS). RESULTS: The mean JAMA score was 1.58 on YouTube and 2.83 on WebSurg (P < .001). The median GQS was 2 on YouTube and 5 on WebSurg (P < .001). The median LAP-VEGaS score was 8 on YouTube and 14.5 on WebSurg (P < .001). The median LDP-SS score was 6 on YouTube and 9.5 on WebSurg (P = .001). According to the LAP-VEGaS, eleven (91.7%) of the WebSurg videos had a high score of 11 or more (P = .04). According to Spearman correlation analysis, there was a statistically significant positive correlation between LDP-SS and JAMA, GQS and LAP-VEGaS (r: .589, P = .002; r: .648, P = .001; r: .848, P < .001 respectively). CONCLUSIONS: The WebSurg is superior to the YouTube in terms of educational and academic value, quality, accuracy, reliability and usability in scientific meetings for LDP videos.

The utility of systemic immune inflammatory index in discriminating between gallbladder cancer and xanthogranulomatous cholecystitis: A single-tertiary center experience.

Xanthogranulomatous cholecystitis (XGC) and gallbladder carcinoma (GBC) are rare diseases with several similarities. This study aimed to evaluate the utility of the systemic immune inflammatory index (SII), a novel index that more accurately depicts inflammatory and immunological balance, in distinguishing between XGC and GBC. This retrospective study included 33 XGC, 22 GBC patients diagnosed according to histopathological findings and 33 age-sex-matched healthy controls at Hacettepe University Faculty of Medicine, General Surgery Department. The demographic, clinical and laboratory findings were recorded. Neutrophil to lymphocyte ratio, platelet to lymphocyte ratio, monocyte to lymphocyte ratio and SII were calculated from preoperative complete blood count parameters. The receiver operating characteristic curve was performed to evaluate the utility of SII in differentiating GBC and XGC. A P value < .05 was accepted as statistically significant. The preoperative neutrophil to lymphocyte ratio, monocyte to lymphocyte ratio, platelet to lymphocyte ratio and SII were significantly higher in patients with GBC compared to XGC patients and healthy controls (P < .001, P = .001, P = .001, P < .001, respectively). When receiver operating characteristic analysis was made, the optimal cutoff value of SII was 640 for differential diagnosis of XGC and GBC preoperatively with a sensitivity of 77.3% and a specificity of 66.7%, among which the positive likelihood ratio was 2.32, and Youden index was 0.44 (P = .006). The positive predictive value was 60.7%, the negative predictive value was 81.5%, and the diagnostic accuracy was 79.9%. SII may be a valuable, practical, and affordable method to differentiate between XGC and GBC, in addition to clinical and radiological signs, prior to surgery. When supported by prospective trials with a larger study population, distinguishing GBC from XGC using SII preoperatively may lead to a change in the management practice of GBC.

Long-Term Declines in Physical Fitness and Physical Activity for Individuals With Post-Liver Transplantation Compared to Healthy Controls.

Functional changes are essential determinants of mortality and morbidity in individuals with chronic liver disease. However, there is limited information about whether these changes persist long-term after liver transplantation (LT). We aimed to compare physical fitness, physical activity, balance, kinesiophobia, and fatigue between patients with LT and healthy controls. All participants underwent evaluation with the Senior Fitness Test (SFT) for exercise capacity and physical fitness, the International Physical Activity Questionnaire (IPAQ) for physical activity, the Timed Up-and-Go Test (TUG) and the Berg Balance Scale (BBS) for balance, the Tampa Scale for Kinesiophobia (TSK) for kinesiophobia, and the Fatigue Severity Scale (FSS) and Fatigue Impact Scale (FIS) for fatigue. We studied 16 persons with LT (M age = 40.56, SD = 15.73 years; M time since LT = 66.81, SD = 72.05 months) and 16 control participants (M age = 39.87, SD = 13.98 years). Compared to controls, participants with LT showed significantly poorer performance on the SFT components assessing upper and lower body strength, aerobic endurance, agility, and dynamic balance (p < .001 for all), significantly lower IPAQ physical activity scores (p = .002) and BBS score (p = .017), and significantly higher TUG time (p < .001) and TSK, FSS, and FIS scores (p = .001, p = .001, and p = .004, respectively). Individuals with post-LT had lower exercise capacity, physical fitness, balance, and physical activity, and higher kinesiophobia and fatigue levels in the long-term compared to their peers. Future studies should focus on frailty in individuals in the long term after LT.

Diagnosis and surgical treatment of cysto-gastric fistula out of an hepatic hydatid cyst. Unusual case.

BACKGROUND: Hydatid cyst is an endemic zoonotic infection that annual incidence ranges from <1 to 200 per 100,000 individuals. The most common complication of hepatic hydatid cyst reported is rupture of the cysts, most commonly intrabiliary rupture. Direct rupture to hollow visceral organs is rarely seen. We describe here an unusual cystogastric fistula in a patient with liver hydatid cyst. CASE PRESENTATION: The 55-year-old male patient presented with right upper quadrant abdominal pain. After radiological imaging studies, the diagnose was of hydatid cyst involving the left lateral segment of the liver ruptured into the gastric lumen and resulted in a cystogastric fistula. Gastroscopy revealed that the cyst and its contents protruding from anterior wall to the gastric lumen. Partial pericystectomy and omentopexy were performed and the gastric wall was primarily repaired. There were no complications in the postoperative period and 3-month follow up. CONCLUSION: This case, to our knowledge, is the first reported case of cystogastric fistula surgically treated in a patient with liver hydatid cyst in the literature. Our clinical experience shows that, although it is a benign disease, complicated hydatid cysts should be evaluated in detail preoperatively, and after the detailed diagnostic work-up, surgical therapy might be planned individually for each case. KEY WORDS: Cysto-gastric fistula, Hydatid Cyst, Liver hydatidosis.

Can endocan serve as a molecular "hepatostat" in liver regeneration?

BACKGROUND: Intriguingly, liver regeneration after injury does not induce uncontrolled growth and the underlying mechanisms of such a "hepatostat" are still not clear. Endocan, a proteoglycan, was implicated in liver regeneration. It can support the function of hepatocyte growth factor/scatter factor in tissue repair after injury. Endostatin, a 20 kDa C-terminal fragment of collagen XVIII, may modulate the cessation of liver regeneration. eEF2K, a protein kinase that regulates protein synthesis, can regulate angiogenesis. Thus, we investigated the role of endocan, endostatin and eEF2K during normal liver regeneration. METHODS: Serum samples and regenerating remnant liver tissues were obtained on various days after partial hepatectomy in rats. mRNA expression levels of Vegf and Pcna were analyzed in addition to immunohistochemical evaluations. Liver tissue protein levels of endostatin, endocan and p-eEF2K/eEF2K were determined with Western blot. Serum levels of endostatin and endocan were assessed with ELISA. RESULTS: Pcna expression level in residual liver tissues peaked on day-1, while Vegf expression reached its highest level on days 1-3 after partial hepatectomy (70%). Endocan activity declined gradually on days 1-7. The decrease in liver endocan expression was accompanied by an increase in serum endocan levels. Partial hepatectomy induced a rapid increase in liver endostatin levels. Following its surge on day-1, endostatin expression gradually declined, which was accompanied by a peak in serum endostatin. Finally, partial hepatectomy was shown to regulate eEF2K; thus, increasing protein translation. CONCLUSIONS: We revealed possible mechanistic insights into liver regeneration by examining the associations of Pcna, Vegf, endocan, endostatin, eEF2K with hepatic regeneration after partial hepatectomy. Indeed, endocan might serve as a useful biomarker to monitor clinical prognosis in a plethora of conditions such as recovery of donor's remaining liver after living-donor liver transplant. Whether endocan might represent a strategy to optimize liver regeneration when given therapeutically needs to be investigated in future studies.

Factors affecting interval cholecystectomy and mortality in percutaneous cholecystostomy patients.

BACKGROUND: Percutaneous cholecystostomy is an alternative or bridge to cholecystectomy (CCY) in high-risk patients with acute calculous cholecystitis. Our primary aim was to determine the parameters that could be used in interval CCY decision-making and to predict mortality in high-risk patients. METHODS: The medical records of 127 patients who underwent percutaneous cholecystostomy for acute calculous cholecystitis between 2010 and 2018 were retrospectively analyzed. The primary outcomes were the CCY rate and the factors affecting mortality in high-risk patients. Descriptive statistics and receiver operating characteristic analysis were performed using albumin and elective surgery. RESULTS: Of the 127 patients undergoing percutaneous cholecystostomy, elective CCY was performed only in 43.1% of the high-risk patients. The 30-day and 1 year mortality rates were 11% and 17.3%, respectively. The American Society of Anesthesiologists' (ASA) score, Charlson comorbidity index (CCI), the negative predictive factors described in the Tokyo Guidelines 2018, the American College of Surgeons' (ACS) expected mortality rate, and albumin level were found to be significant factors affecting mortality and elective CCY probability. No mortality was observed, and an 82% elective CCY rate was achieved in patients whose albumin levels were higher than 3.16 mg/dL at initial presentation. CONCLUSION: The plasma albumin level, ASA score, CCI, and ACS expected mortality rate can be used to predict mortality and decide on elective CCY. Percutaneous cholecystostomy is sufficient for resolving inflammation, but medical comorbidities determine the final condition of patients.

Minimally invasive techniques in benign and malignant adrenal tumors.

Minimally invasive adrenalectomy has become the main treatment modality for most adrenal lesions. Both laparoscopic transabdominal and retroperitoneoscopic approaches are safe and feasible options, each with respective advantages, including better surgical outcomes, fewer complications, and faster recovery over open adrenalectomy. While open surgery remains a valid modality in treatment of adrenocortical cancer in the presence of some findings such as invasion, robotic platforms, and minimally invasive surgery have gained popularity as technology continues to evolve. Organ preservation during adrenalectomy is feasible in some conditions to prevent adrenal insufficiency. Ablative technologies are increasingly utilized in benign and malignant tumors, including the adrenal gland, with various outcomes. A multidisciplinary team, an experienced surgeon, and a high-volume center are recommended for any surgical approaches and management of adrenal lesions. This review article evaluated recent findings and current evidence on minimally invasive adrenalectomy.

Evaluation of Potential Inflammatory Markers for Cystic Echinococcosis: P-selectin and Resistin

Objective: Cystic echinococcosis (CE) is one of the most common zoonotic diseases worldwide. Diagnosis of CE is predominantly based on imaging techniques and serological tests are used in cases of non-characteristic imaging findings as diagnostic reference. However, serological test results cannot be completely reliable as they are affected by multi-factors. P-selectin and resistin are inflammatory markers that are altered during the acute stages of infection. In this purpose, inflammatory markers as P-selectin and resistin have been investigated for a potential diagnostic reference for CE diagnosis. Methods: A total of 60 patients who were diagnosed with CE and twenty-five healthy individuals were included in this study. Blood samples were obtained from all participants. Obtained sera were evaluated using the P-selectin and resistin ELISA kits for protein levels. Additionally, the relative expression of SELP (P-selectin) and RETN (resistin) genes were determined using the comparative CT (ΔΔCT) method between groups as CE patients with active and inactive cysts, CE patients and healthy controls. Results: SELP (13.9-fold change, p<0.05) and RETN (8.1-fold change, p<0.05) were differentially expressed in CE patients compared in the control group. Whereas resistin protein levels were significantly higher in CE patients than the healthy controls (p<0.001), the difference in P-selectin protein levels was not significant (p>0.05). There was no difference between active and inactive CE patients in terms of P-selectin and resistin in gene and protein levels (p>0.05). Conclusion: Although there was no difference between the active and inactive CE patients, the good differentiation between the healthy controls and the CE patients suggested that resistin is a potential inflammatory diagnostic reference.

Salvage Liver Transplant in the Treatment of a Child With Local Recurrence of Hepatoblastoma.

Hepatoblastoma is the most common primary liver cancer of childhood, accounting for two-thirds of primary malignant hepatic neoplasms. Radical surgical removal combined with efficient chemotherapy is essential for cure. Despite a complete tumor resection, hepatoblastoma may recur as isolated local disease. Intrahepatic recurrence of hepatoblastoma after liver resection is among the indications for liver transplant. Here, we present a patient who underwent salvage liver transplant for the treatment of local recurrence of hepatoblastoma. A 13-year-old boy who was diagnosed with hepatocellular carcinoma arising from the left liver lobe and who had been treated with surgical resection was admitted to our outpatient oncology clinic for further evaluation because alpha-fetoprotein levels had started to increase after surgery. Histopathological reexamination of hemihepatectomy material showed a histological aspect of an epithelial hepatoblastoma. Magnetic resonance imaging revealed multifocal lesions in the right liver lobe compatible with local recurrence. Despite a favorable initial response to chemotherapy, the tumor showed progression with increased alpha-fetoprotein levels. The patient was deemed a viable candidate for an urgent liver transplant and underwent right lobe living donor liver transplant. He had excellent graft function without any complications or signs of malignancy in the last follow-up visit at 7 months posttransplant. Salvage liver transplant is a lifesaving and sometimes the only treatment option for patients with local recurrence of hepatoblastoma. Although transplant in the salvage setting has been associated with worse outcomes than primary transplant, recent data have indicated more favorable and acceptable outcomes. Further studies are warranted to better understand the role of salvage liver transplant in the treatment of hepatoblastoma. Early consultation with the liver transplant team is critical in children who are most likely to need extreme resection or liver transplant.

A Fatal Complication of Liver Transplant: Posttransplant Lymphoproliferative Disease.

Immunosuppressive therapy is a double-edged sword and causes a risk for some complications, such as opportunistic infections and posttransplant lymphoproliferative disease. The most likely risk factors for posttransplant lymphoproliferative disease are Epstein-Barr virus serology mismatch, prolonged and high viral load for Epstein-Barr virus, higher doses of immunosuppressive therapy, and cytomegalovirus infection. Transplant recipients who are seropositive for Epstein-Barr virus show a lower risk for posttransplant lymphoproliferative disease than seronegative recipients. Here, we present a 3.5-year-old boy who was seropositive for Epstein-Barr virus and developed posttransplant lymphoproliferative disease 18 months after liver transplant with a previous history of cytomegalovirus- related pneumatosis intestinalis.

Metabolomic profiling of active and inactive liver cystic echinococcosis.

Cystic Echinococcosis (CE) is one of the life-threatening diseases worldwide. It is a parasitic zoonosis caused by tapeworms of the species Echinococcus granulosus sensu lato (s.l). The treatment options of CE vary from simple "watch and wait" approach to invasive treatment, based on the type and especially the nature of the cyst (active/inactive). Serological tests are inadequate to distinguish between active and inactive CE. A diagnostic reference that can determine whether the cyst is active or inactive can easily guide the treatment strategy. We aimed to test whether gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-quadropole time of flight mass spectrometry (LC-qTOF-MS) based metabolomics can establish a plasma metabolic fingerprint of CE patients and identify a diagnostic reference to discriminate active and inactive CE cysts. Metabolite concentrations were measured in plasma samples of 36 active CE patients, 17 inactive CE patients and 31 healthy controls. Multivariate statistical analysis on 232 identified metabolites obtained from two analytical platforms was performed by using principle component analysis (PCA) and partial least square-discriminant analysis (PLS-DA) methods. The PLS-DA scores plot of the combined data set demonstrated a good separation between the groups. Compared to the healthy control group, decreased levels of squalene and increased levels of glyceric acid, 3-phosphoglycerate, glutamic acid, palmitoleic acid and oleic acid were determined in the CE patients. However, decreased levels of 3-phosphoglycerate and increased levels of 4-hydroxyphenylacetylglutamine, docosahexanoic acid were determined in active CE patients compared to the inactive CE patients. Determination of differences in metabolites may provide detailed understandings of potential metabolic process associated with active and inactive CE patients, and altered specific metabolic changes may provide some clues to obtain diagnostic reference for CE. This study has certain limitations: a. various factors affecting results of metabolomic studies such as lifestyle and dietary habits of the patients could not be fully controlled b. other infectious or malignant diseases of the liver should also be included as a positive control to evaluate the specificity of the diagnostic references.

Determination of risk factors for progression in patients with viable tumor at post-chemotherapy lymph node dissection due to disseminated non-seminomatous germ-cell tumors.

BACKGROUND: To assess the clinical variables that effect progression in patients with viable tumor after post-chemotherapy lymph node dissection due to disseminated non-seminomatous germ-cell tumors. METHODS: We performed a retrospective analysis of 32 patients with viable tumor after PC-RPLND, operated between 1990 and 2016. Patients were categorized into 2 groups as favorable and non-favorable (intermedia and poor) according to International Germ Cell Consensus Classification (IGCCC). Tumor size was determined as the largest dimension of retroperitoneal mass. Clinical factors and adjuvant chemotherapy were evaluated to impact on recurrence free survival (RFS) and overall survival (OS). RESULTS: The median age of the patients and follow-up duration were 28.5 (17-51) years and 51.5 (4-253) months, respectively. 5-year RFS and OS were 57.8-66.8%, respectively. On univariate analysis, percentage of viable tumor, IGCCC risk group, primary site, second-line chemotherapy and surgical margin status were significant for RFS (p = 0.034, p = 0.002, p < 0.001, p = 0.011 and p < 0.001, respectively), while IGCCC risk group, second-line chemotherapy and surgical margin status were significant for OS (p = 0.004, p = 0.010 and p < 0.001, respectively). On multivariate analysis, second-line chemotherapy and surgical margin were independent risk factors for RFS (p = 0.016, HR 4.927 95% CI 1.34-18.02 and p < 0.001, OR 9.147 95% CI 2.61-31.98, respectively) and surgical margin status was the only predictor of OS (p = 0.038, HR 3.874 95% CI 1.07-13.69). CONCLUSION: Retroperitoneal lymph node dissection with negative surgical margin is essential for patients with viable residual tumor after chemotherapy. Need for second-line chemotherapy shows risk of progression.

Does Preoperative Comprehensive Geriatric Assessment and Frailty Predict Postoperative Complications?

BACKGROUND: The influence of preoperative comprehensive geriatric assessment and frailty on postoperative morbidity, mortality, delirium were examined. METHODS: A total of 108 patients were evaluated. The Katz Index of Independence in Activities of Daily Living (ADL), the Lawton Brody Instrumental Activities of Daily Living Scale (IADL), the Mini-Nutrition Assessment test (MNA), the Mini-Mental State Examination (MMSE), Yesavage Geriatric Depression Scale (GDS) were performed. Fried Criteria were used to assess physical frailty. We used the Physiological and Operative Severity Scores for the Enumeration of Mortality and Morbidity score (POSSUM), the American Society of Anesthesiologists Score (ASA), and the Charlson Comorbidity Index (CCI) to determine the risk of postoperative morbidity and mortality. Assessment Test for Delirium (4AT) was applied for detection of delirium. RESULTS: The median age was 71 years (min-max: 65-84). IADL (p = 0.032), MNA (p = 0.01), MMSE scores (p = 0.026) were found to be significantly lower in patients with morbidity. POSSUM physiology score (p = 0.005), operative score (p = 0.015) and CCI (p = 0.029) were significantly higher in the patients with morbidity. Patients developed morbidity were found to be more frail (p < 0.001). The patients with delirium were found to have lower IADL (p = 0.049) and MMSE scores (p = 0.004), higher POSSUM physiology score (p = 0.005) and all of them were frail. It was found that frailty (OR = 23.695 95% CI: 6.912-81.231 p < 0.001), POSSUM operative score (OR:1.118 95% CI: 1.021-1.224 p = 0.016) and preoperative systolic blood pressure (OR:0.937%95 CI: 0.879-0.999 p = 0.048) were independently related factors for postoperative morbidity. CONCLUSION: In our study, CGA and frailty in preoperative period were found to be indicators for postoperative morbidity and delirium.

Management of a Pregnancy with a Solid Pseudopapillary Neoplasm of the Pancreas.

A 26-year-old primigravid patient, at 35 weeks and 2 days of gestation, was referred to Hacettepe University Hospital for pancreatic mass, giant cervical myoma, maternal systemic lupus erythematosus, thrombocytopenia, and onset of preterm labor. At 36 weeks and 1 day of gestation (6 days after admission to the hospital), regular uterine contractions started and cervical dilatation with effacement was observed. Because of breech presentation and giant cervical myoma, a cesarean section was performed on the primigravid patient under general anesthesia. Four months after the birth, subtotal pancreatectomy, partial gastrectomy, duodenectomy, cholecystectomy, and omentectomy (Whipple procedure) were performed. The pathologic diagnosis was of a solid pseudopapillary neoplasm of the pancreas; the patient was discharged from hospital after ten days.

Mesothelial Cysts of the Round Ligament of the Uterus in 9 Patients: a 15-year experience.

Aim of this study was to evaluate the characteristic features of patients with mesothelial cyst of the round ligament of the uterus and the incidence of this entity. This was a retrospective review of 3065 patients who underwent inguinal exploration for groin mass from 1998 to 2013. Clinical, radiological and histopathological features of patients with a diagnosis of mesothelial cyst of the round ligament were analyzed. Of the 405 female patients reviewed 9 mesothelial cysts of the round ligament were identified (2.2%). The median age was 37 (range 19-82 years). In all patients the groin mass was manually irreducible on physical examination. The lesions were on the right side in 6 (66.6%) patients. These were identified before surgery in 4 (all by groin ultrasonography). Three were misidentified as a hernia before surgery. The remaining 2 (22%) had both hernia and the mesothelial cyst of the round ligament. The cysts were identified after surgery at the time of histopathological examination in these two patients. In all patients histopathological examination revealed multilobular cystic lesion lined by a single layer of mesothelial cells. Cystic lesions arising from the round ligament were identified and excised along with the round ligament in 7 patients. In the remaining 2, a hernia repair was also performed. There was no recurrence at follow-up. Mesothelial cysts of the round ligament are rare. They are easily misidentified as groin hernia. An accurate diagnosis requires a high index of suspicion and is greatly aided by preoperative imaging studies.
