    Abstract Despite the novel and innovative developments in minimal invasive platforms and the expanding indications regarding adrenal surgery, surgeons are still confronted with some obstacles. The use of intraoperative indocyanine green aims to overcome these problems, but there is still limited data and ongoing debates in terms of robot-assisted adrenal surgery. The aim of this article is to discuss the benefit of indocyanine green fluorescence imaging for robot-assisted adrenalectomy and provide up-to date data.

    Abstract Aim: Angiolipoma is uncommon lesion in the breast and has clinical importance due to the potential of confusion with malignant breast lesions. To date, there is no defined diagnosis and treatment algorithm for breast angiolipomas. We aim to contribute to the literature for the diagnosis and treatment of angiolipomas with this case report and literature review.
    Case report: A 29-year-old male patient presented with a newly emerged palpable mass in the right breast. Physical examination revealed a palpable mass in the lower inner quadrant of the right breast without any presence of skin changes, nipple discharge or palpable axillary lymph nodes. The lesion was found to be 3 cm in diameter and showed minimal vascularization on Doppler Ultrasound examination. Surgical excision of the lesion was performed and the lesion was diagnosed as angiolipoma.
    Conclusion: Angiolipomas of the breast in male are rare pathological entities and must always be considered during differential diagnosis, as it can be confused clinically, radiologically and pathologically with other lesions, especially with malignant lesions KEY WORDS: Angiolipoma, Breast, Male breast lesions.

    Abstract Background/aim: Colorectal cancer (CRC) is one of leading cancers in terms of incidence and mortality. Interaction of tumor cells with the surrounding microenvironment plays a crucial role in the development and progression of CRC. Many pathways such as the kynurenine pathway, OX40/OX40L-mediated signaling and microRNAs targeting PD-L1 may be involved in CRC development by affecting T cell activation, thus creating an immune-deficient microenvironment. Herein, our goal was to assess the association between plasma levels of tryptophan (TRP), kynurenine (KYN), KYN/TRP ratio, soluble OX40 (sOX40) and PD-L1-targeting miR-138-5p and CRC risk.
    Patients and methods: Plasma concentrations of TRP and KYN were determined by HPLC; sOX40 was measured by ELISA whereas circulating miR-138-5p was measured by quantitative PCR in pathologically confirmed CRC patients and colonoscopy-verified CRC-free controls without polyps (control group 1) and with polyps (control group 2).
    Results: We found significantly lower plasma levels of TRP in CRC patients compared to control groups which resulted in significantly higher KYN/TRP ratio in CRC patients than in the controls (p=0.007). Plasma levels of sOX40 did not significantly differ between groups. The levels of circulating miR-138-5p were significantly lower in CRC patients (relative median value 0.02) than in the control groups (relative median values 0.2 and 4.29, respectively) (p=0.03). Plasma levels of KYN and sOX40 were considerably higher in patients with no tumor-infiltrating lymphocytes (TILs) than those with TILs whereas circulating miR-138-5p had opposite expression pattern in plasma.
    Conclusion: The kynurenine pathway and miR-138-5p are associated with CRC risk and plasma levels of KYN, sOX40 and miR-138-5p are related to TILs, making them possible target molecules in possible immunotherapeutic targets for CRC.

    Abstract Background: The coronavirus disease 2019 (COVID-19) pandemic has affected all aspects of clinical care including diagnosis and treatment of colorectal cancers (CRCs) globally, including in Türkiye. During the initial peak of the pandemic, elective surgeries and outpatient clinics were restricted in addition to the government-imposed lockdown, resulting in a decrease in the number of colonoscopies being performed and patients admitted to inpatient wards for treatment of CRCs. In this study, we aimed to investigate whether the pandemic has affected presentation characteristics and outcomes of obstructive colorectal cancer in this period.
    Methods: This is a single-center, retrospective cohort study based on all CRC adenocarcinoma patients that underwent surgical resection in a high-volume tertiary referral center in Istanbul, Türkiye. Patients were divided into two groups before and after 15 months of identification of 'patient-zero' in Türkiye (March 18, 2020). Patient demographics, initial presentation characteristics, clin-ical outcomes, and pathological cancer stages were compared.
    Results: Overall, 215 patients underwent resection for CRC adenocarcinoma during 30 months (COVID era: 107, pre-COVID era: 108). Patient characteristics, tumor location, and clinical staging were comparable between two groups. During the COVID period, the number of obstructive CRCs (P<0.01) and emergency presentations (P<0.01) increased significantly compared to the respective pre-COVID period. However, there were no differences between 30-day morbidity, mortality, and pathological outcomes (P>0.05).
    Conclusion: Although the results of our study indicate a significant increase in emergency presentation and a decrease in elective admissions of CRCs during the pandemic, patients treated during the COVID period were not at a significant disadvantage in terms of post-operative outcomes. Further efforts should be made to decrease risks related to an emergency presentation of CRCs for future adverse events.

    Abstract Introduction: F-18 fluorodeoxyglucose (F18-FDG) positron emission tomography-computed tomography (PET/CT) is a valuable functional imaging modality for the clinical diagnosis which provides physiological information based on the altered tissue metabolism.

    Aim: This study aims to investigate the effectiveness of F-18 fluorodeoxyglucose (F18-FDG) positron emission tomography-computed tomography (PET/CT) in preoperative staging and postoperative local recurrence and distant metastases in patients with rectal cancer.

    Material and methods: The imaging of 726 patients with rectal cancer who were operated on at Istanbul University, Istanbul School of Medicine and had F18-FDG PET/CT, CT, and magnetic resonance imaging (MRI) scans between September 2005 and October 2016 were retrospectively analyzed. Of these patients, 170 who had pre- and postoperative PET/CT scans, had their CT scans included in the study. The sensitivity and specificity of PET/CT in preoperative staging and detection of postoperative local recurrence and distant metastases were analyzed.

    Results: Of the patients, 101 were males and 69 were females with a median age of 62.27 (range, 31 to 89) years. The sensitivity and specificity of preoperative PET/CT in detecting liver metastases were 100% (confidence interval [CI]: 66.37-100%) and 94.2% (CI: 89.72-100%), respectively (Cohen's kappa [κ]: 1.00; P < 0.001). The sensitivity and specificity of postoperative PET/ CT in diagnosing liver metastases were 100% (CI: 88.06-100%) and 98% (CI: 9-100%), respectively (Cohen's κ: 1.00; P < 0.001). The sensitivity and specificity of preoperative PET/CT in detecting lung metastases were 100% (CI: 66.37-100%) and 91.8% (CI: 89.72-100%), respectively (Cohen's κ: 1.00; P < 0.001). The sensitivity and specificity of postoperative PET/CT in detecting lung metastases were 100% (CI: 91.4-100%) and 96% (CI: 95.8-100%), respectively (Cohen's κ: 1.00; P < 0.001). The sensitivity and specificity of PET/CT in preoperative staging of pathological pelvic lymph nodes were 100% (CI: 63.06-100%) and 94.29% (CI: 80.84-99.3%), respectively (Cohen's κ: 0.860; P < 0.001). The sensitivity and specificity of postoperative PET/CT in detecting local recurrences were 100% (CI: 78.2-100%) and 76.74% (CI: 61.37-88.24%), respectively (Cohen's κ: 0.219; P < 0.08).

    Results: Given the fact that PET/CT can detect all primary rectal cancer in preoperative staging, it can be effectively used in selected cases, particularly in those suspected of local and advanced disease and with metastases (T3N0, T3N1, and/or T4N1). Due to a relatively low specificity in detecting local recurrences postoperatively, PET/CT can be combined with further modalities.

    Abstract Background: The location of colonic tumors has been linked to different clinical and oncologic outcomes. Transverse colon cancers are generally included as right colon cancers. Furthermore, hepatic and splenic flexure tumors are usually included as components of the transverse colon.
    Objective: This study was aimed at comparing the clinicopathologic characteristics and long-term outcomes between mid-transverse and right and left colon cancers and determining the prognostic impact of the primary tumor location in the mid-transverse colon.
    Design: This was a retrospective study.
    Settings: Two specialized colorectal centers were included.
    Patients: Patients who underwent curative surgery for colon cancer were analyzed. Tumors located in the transverse colon, excluding the flexures, were defined as mid-transverse colon cancers.
    Main outcome measures: Demographic characteristics, operative outcomes, pathologic results, and long-term outcomes were the primary outcome measures.
    Results: Of the 487 patients, 41 (8.4%) had mid-transverse, 191 (39.2%) had right, and 255 (52.4%) had left colon cancers. For mid-transverse colon cancers, the mean length of hospital stay, mean length of the resected specimen, and the mean number of harvested lymph nodes were significantly higher. For patients with stage I to III cancer, the 5-year overall and disease-free survival rates were significantly worse in the mid-transverse colon cancers than in the right and left colon cancers (overall survival: 55.5% vs 82.8% vs 85.9%, p = 0.004, and disease-free survival; 47.7% vs 72.4% vs 79.5%, p = 0.003). After adjustment for other clinicopathologic factors, mid-transverse colon cancers were significantly associated with a poor prognosis (HR = 2.19 [95% CI, 1.25-3.83]; p = 0.006).
    Limitations: Molecular and genetic information were unavailable in this retrospective study.
    Conclusions: In our case series, colon cancers located in the mid-transverse colon showed poorer prognosis than cancers in other locations. The impact of tumor location in the mid-transverse colon on prognosis, including molecular and genetic markers, should be investigated further in prospective studies.

Los cánceres de colon transverso se incluyen generalmente como cánceres de colon derecho. Además, los tumores del ángulo hepático y esplénico suelen incluirse como un componente del colon transverso.OBJETIVO:Este estudio tuvo como objetivo comparar las características clínico-patológicas y los resultados a largo plazo entre los cánceres de colon transverso medio y derecho e izquierdo y determinar el impacto pronóstico de la ubicación del tumor primario en el colon transverso medio.DISEÑO:Este fue un estudio retrospectivo.AJUSTE ENTORNO CLINICO:Se incluyeron dos centros colorrectales especializados.PACIENTES:Se analizaron los pacientes que fueron sometidos a cirugía curativa por cáncer de colon. Los tumores ubicados en el colon transverso, excluidos los ángulos, se definieron como "cánceres de colon transverso medio".PRINCIPALES MEDIDAS DE RESULTADO VOLARACION:Las características demográficas, los resultados quirúrgicos, los resultados patológicos y los resultados a largo plazo fueron las principales medidas de resultado valoracion.RESULTADOS:De los 487 pacientes, 41 (8,4%) tenían cáncer de colon transverso medio, 191 (39,2%) derecho y 255 (52,4%) cáncer de colon izquierdo. Para los cánceres de colon transverso medio, la duración media de la estancia hospitalaria, la duración de la muestra resecada y el número medio de ganglios linfáticos extraídos fueron significativamente mayores. Para los pacientes en estadio I-III, las tasas de supervivencia general y sin enfermedad a 5 años fueron significativamente peores en los cánceres de colon transverso medio que en los cánceres de colon derecho e izquierdo (supervivencia general: 55,5% frente versus a 82,8% frente versus a 85,9%, p = 0,004 y supervivencia libre de enfermedad; 47,7% frente a 72,4% frente a 79,5%, p = 0,003, respectivamente). Después del ajuste por otros factores clínico-patológicos, los cánceres de colon transverso medio se asociaron significativamente con un pronóstico desfavorable (Razón de riesgo: 2,19; intervalo de confianza del 95%: 1,25-3,83; p = 0,006).LIMITACIONES:La información molecular y genética no estuvo disponible en este estudio retrospectivo.CONCLUSIONES:En nuestra serie de casos, los cánceres de colon localizados en el colon transverso medio mostraron un peor pronóstico que los cánceres en otras localizaciones. El impacto de la ubicación del tumor en el colon transverso medio sobre el pronóstico, incluidos los marcadores moleculares y genéticos, debe investigarse más a fondo en estudios prospectivos.

    Abstract Aim: This study aims to assess the completeness of pathology reports of T1 colorectal cancers from different healthcare centers and the change of treatment decision after reevaluation of the polyps.
    Materials and methods: In this single-center retrospective cohort study, several pathology reports of endoscopically excised malignant colorectal polyps at diverse healthcare centers in Turkey were reassessed at a comprehensive cancer center in Istanbul. Reassessment was mainly focused on core elements such as the size of invasive carcinoma, histologic type and grade, tumor extension, surgical margin (deep and mucosal), and lymphovascular invasion.
    Results: Sixty-seven endoscopically resected malignant polyps were analyzed. The mean age of patients was 62.2 years and 38 (58%) patients were males. Tumor size, histologic type and grade, surgical margin (deep and mucosal), and lymphovascular invasion were reported in 11%, 100%, 31%, 9%, and 19%, respectively. All 5 prognostic factors were reported only in 1 (1.5%) pathology report. Because of the missing (incomplete) data, the pathologic examination of 59 (88%) patients was determined to be inadequate to make an accurate treatment decision.
    Conclusion: Several variables are not considered and frequently missing for decision-making, suggesting the reassessment of the specimen by a second pathologist at a high-volume comprehensive cancer center.

    Abstract Background: The novel coronavirus disease 2019 (COVID-19) has resulted in major changes in health-care systems and emer-gency surgical interventions. Here, we examined patients with acute appendicitis who presented to emergency departments and com-pared diagnosis, treatment, and post-treatment processes before and during the pandemic period and investigated how the pandemic affected management of acute appendicitis.
    Methods: A national, multicenter, and cohort study model was designed that included patients older than 18 years of age diag-nosed with acute appendicitis clinically and/or radiologically, with patients compared before (pre-pandemic period: January 1-April 30, 2019) and after (pandemic period: January 1-April 30, 2020) the pandemic. Our investigation included comparisons of pre-operative imaging methods, presence of plastron appendicitis/abscess, conservative/surgical approach, type of anesthesia given, laparoscopic/open surgical approach, bowel resection rates, drain insertion rates, and presence of post-operative complications RESULTS: For the two study groups, 8972 patients from 69 centers were examined, with 4582 patients operated in the pre-pan-demic period and 4234 patients operated in the pandemic period. During the pandemic period, 63.6% of patients underwent open surgery, whereas 34.4% had laparoscopic surgery. Although 60 patients (1.3%) requested non-operative follow-up in the pre-pandemic period, 94 patients (2.2%) requested this in the pandemic period. When conditions of patients were evaluated regardless of their own wishes, 114 patients (2.4%) before and 163 patients (3.8%) during the pandemic received non-operative follow-up.
    Conclusion: Our study did not show the direct correlation between the application of COVID-19-related restrictions and the severity of acute appendicitis. Although non-operative management rates have been increased during the COVID-19 period, the incidences of both complicated and the uncomplicated appendicitis were similar during the COVID-19 crisis period. Given this infor-mation non-operative management can be employed for patients diagnosed with appendicitis.

    Abstract Abstract: Surgical resection is an unavoidable part of the current treatment options for Crohn's disease (CD), and more than half of patients develop recurrence. The aim of this study was to investigate the predictors for recurrence in the long-term follow-up of CD patients after surgery.Medical records of consecutive CD patients who were operated on between January 2003 and January 2015 were retrospectively analyzed. Data including demographic and clinical characteristics of the patients were recorded. Recurrence was evaluated based on the Crohn's Disease Activity Index or endoscopic findings.The majority of 112 patients were males (n = 64, 57.1%), and 61 (54.4%) of them were active smokers. The median follow-up was 113 (range: 61-197) months. Disease recurrence occurred in 16 (14.3%) patients at a median of 13.5 months. The endoscopic recurrence rate was 8% (n = 9) at 1 year, 12.5% (n = 14) at 5 years, and 13.4% (n = 15) at 10 years. One (0.9%) patient underwent colonoscopic balloon dilatation at 1 year, and 7 (6.3%) patients needed re-resection at a median of 36 months. The age of the patient at the time of diagnosis (P = .033), penetrating disease behavior (P = .011), intra-abdominal abscess (P = 0.040) and, concomitant fistula and intra-abdominal abscess (P = .017) were associated with disease recurrence.Our study results suggest that the patients' age at the time of diagnosis, penetrating disease, intra-abdominal abscess, and concomitant fistula and abscess are the risk factors for CD recurrence after surgery.
