Diagnostic Value of Neutrophil to Lymphocyte Ratio for Assessing Obstructive Sleep Apnea Risk in Surgical Patients.

PURPOSE: Obstructive sleep apnea (OSA) is an important risk factor leading to perioperative complications in surgical patients. Neutrophil-to-lymphocyte ratio (NLR) is an important biomarker of increasing interest in recent years, and is used in the determination of systemic inflammatory response. DESIGN: The aim of this study was to evaluate the risk of OSA and the relationship between OSA risk and NLR in surgical patients. METHODS: The study was conducted in a tertiary care hospital between November 2021 and May 2022. The cross-sectional study included 604 patients who underwent surgery. OSA risk was evaluated with the STOP-Bang questionnaire in the preoperative evaluation in all patients. NLR was calculated as the ratio of neutrophil count to lymphocyte count. FINDINGS: According to the STOP-Bang questionnaire, 62.3% of the patients had a high risk of OSA in the preoperative period. Patients who were male, elderly, obese, had hypertension, diabetes, chronic lung disease, and heart disease and polypharmacy were at greater risk of OSA. Patients at high risk of OSA had significantly higher NLR than patients at low risk of OSA. (2.65 vs 2.92, P.ß=.ß.024). NLR of 2.40 or higher predicted OSA risk with 58.8% sensitivity and 51.0% specificity (AUC.ß=.ß0.561) CONCLUSIONS: Most patients who were to undergo surgery had a high risk of OSA. NLR was higher in patients at high risk of OSA. Although the diagnostic efficacy is not high, NLR can be used to detect high OSA risk because it is a low-cost and easy to obtain biomarker.

Clinical characteristics of appendiceal diverticular disease.

BACKGROUND: Appendiceal diverticular disease (ADD) is a rare pathology which is associated with an increased mortality risk due to rapid perforation and high rates of neoplasm. In our study, we aimed to evaluate the clinical and histopathological characteristics of ADD with differences from acute appendicitis (AA) diagnosis and to determine the association with neoformative processes. METHODS: The 4279 patients who underwent appendectomy were evaluated retrospectively. ADD patients histopathologically classified into four groups. Patients' demographic characteristics, imaging and preoperative laboratory findings, additionally postoperative histopathology results were compared between groups. RESULTS: The prevalence of ADD was 2.29% (n = 98). In addition, the male/female ratio was 2.37 in ADD patients who were found to be significantly older than those with AA patients. Type III was the most frequently (62.2%) identified sub-group of ADD. The incidence of neoplasms, plastrone, and Littre's hernia was found statistically higher in ADD group than AA group. Mucinous adenomas (10.2%) was the most common neoplasm while the carcinoid tumor (1%) and precancerous serrated adenomas (4.1%) were also reported. CONCLUSIONS: As a result, high neoplasm in ADD patients can be shown with incidence of perforation and plastron, and in order to avoid possible neoplasm or major complications, it is necessary to carry out new studies for the right diagnosis of ADD whether the diagnosis is done preoperatively or intraoperatively. We recommend surgical resection of the ADD, which may even be incidentally detected during any surgical procedure, due to its high risk of neoplasm and rapid perforation.

Postoperative surgical margin results of the phyllodes tumors from a tertiary hospital.

OBJECTIVE: Phyllodes tumors in the breast are exceptionally uncommon fibroepithelial tumors. In the literature, they are typically categorized as benign phyllodes tumor, borderline phyllodes tumor, and malignant phyllodes tumor. This study aims to assess and present the clinical and surgical outcomes of patients diagnosed with phyllodes tumor. METHODS: The outcomes of patients aged 18 years and above diagnosed with phyllodes tumor between 2006 and 2023 were retrospectively reviewed. Patients were grouped as benign phyllodes tumor and borderline/malignant phyllodes tumor and compared by clinical and surgical results. RESULTS: Of all 57 patients with phyllodes tumor, 64.9% (n=37) were benign phyllodes tumor and 35.1% (n=20) were borderline/malignant phyllodes tumor [22.8% (n=13) borderline phyllodes tumor and 12.3% (n=7) malignant phyllodes tumor]. When the patients were divided into two groups as benign phyllodes tumor and borderline/malignant phyllodes tumor and compared, our cumulative (total) recurrence rate was 14.0%, with final surgical margin width between groups [(0

The effect of total size, area, and volume of lesions in multifocal/multicentric breast cancers and unifocal breast cancers on survival: An observational study.

In this study, we aimed to investigate the prognostic effect of the classifications made according to the stage of the largest lesion diameter (T-max stage) and of the sum of the longest diameters of the lesions (T-sum stage), the largest area stage (A-max stage), the sum of the largest areas (A-sum stage), the highest volume stage (V-max stage), the sum of the highest volume (V-sum stage) on disease-free survival, and overall survival (OS) in multifocal/multicentric breast cancers (MMBCs) and unifocal breast cancers (UBCs). The study included a total of 769 patients either with MMBC (n = 128) or UBC (n = 641) who underwent surgery between 2006 and 2015. In the analysis, the median age of 769 patients was 53.0 (20.0-94.0) years, and 16.6% of these 769 patients were MMBC and 83.4% were UBC. In multivariate analysis, lymphovascular invasion (LVI), estrogen receptor, and nodal status were common independent prognostic factors, whereas T-max stage [(HR: 1.17) (CI 95%: 1.03-1.33) (P = .018)] was a prognostic factor for OS. In multivariate analysis, the T-max stage is an independent risk factor for OS. Therefore, T-max should be continued to be used for measurement and T-stage should be used for classification in MMBCs/UBCs.

Identifying Factors Associated with Non-mesenterovascular Pathology in Patients Undergoing Surgical Treatment for Acute Mesenteric Ischemia.

AIM: To identify factors that can help us to avoid a preoperative incorrect diagnosis of vascular occlusion by evaluating patients who underwent laparotomy with a probable preoperative diagnosis of acute mesenteric ischemia (AMI), but later at laparotomy, were diagnosed to have a different pathology than AMI. MATERIAL AND METHODS: A total of 213 patients who were operated with the diagnosis of AMI were enrolled in this study. Based on their operational, clinical, and pathological findings, they were divided into two groups. Patient demographic data, along with the American Society of Anesthesiology (ASA) score, Charlson comorbidity index, history of previous abdominal surgery, and computed tomography (CT) findings were compared between groups. RESULTS: There were 37 patients in Group 1 (non-mesenterovascular pathology) and 176 patients in Group 2 (mesenterovascular pathology). The percentage of ASA 4 patients was higher in Group 2, with 48.3%, compared to 35.1% in Group 1 (p-value: 0.028). Upon admission, Group 2 had a higher rate of pathologic findings on CT examinations. 21.8% of the patients with non-mesenterovascular pathology had normal intra-abdominal findings. In univariate and multivariate analysis for no-nmesenterovascular pathology, patient age less than 65, Charlson comorbidity index 1-2, INR level >1.2, history of previous abdominal operation, and pneumatosis intestinalis were identified as independent risk factors. DISCUSSION: The possibility of non-mesenterovascular pathology in presumed AMI patients should be kept in mind, especially if the patients have a history of abdominal surgery, a low comorbidity index, an elevated international normalised ratio (INR), and are younger than 65 years of age. CONCLUSION: Evaluating the significant parameters identified in this study among patients with a preliminary diagnosis of AMI may prove useful in avoiding misdiagnosis and unnecessary surgeries.

Predictors of recurrence in breast cancer patients with pathological partial response.

OBJECTIVE: Patients with residual disease after neoadjuvant chemotherapy have a relative risk of developing recurrence. This study investigates the risk factors for recurrence in locally advanced breast cancer patients with residual disease and evaluates survival analysis. METHODS: This is a retrospective, single-center study. Breast cancer patients who failed to achieve a pathological complete response after neoadjuvant chemotherapy were included. Demographic, clinicopathological, and treatment characteristics were evaluated to identify predictive factors of recurrence and survival analysis. RESULTS: We included 205 patients in this study. After a median of 31 months of follow-up, 10 patients died, and 20 developed distant metastasis. Disease-free survival and disease-specific survival were 73.8% and 83.1%, respectively. Lymphovascular invasion and non-luminal subtype were independent predictors of locoregional recurrence. In situ carcinoma, lymphovascular invasion, ypTIII stage, and non-luminal molecular subtypes were independent predictors of disease-free survival. The only independent factor affecting disease-specific survival was cNII-III. The number of involved lymph nodes was an independent predictor of disease-free survival in patients without complete axillary response. CONCLUSION: Factors affecting disease-specific survival and disease-free survival were cNII-III and the number of involved lymph nodes, respectively. Patients with non-luminal, large residual tumors with in situ carcinoma, lymphovascular invasion, clinically positive axilla, and residual nodal involvement have a high relative risk for recurrence and may benefit from additional treatments.

Is peripheral blood immunophenotyping useful to understand the etiology of Idiopathic Granulomatous?

BACKGROUND: The etiology of idiopathic granulomatous mastitis (IGM) has not been clearly established. However, autoimmunity has recently become popular in etiopathogenesis. We aimed to investigate the immunophenotyping of immune cells to help clarify the etiopathogenesis of the disease. METHODS: Patients with IGM and healthy volunteers were included in the study. Patients were divided into active and remission groups based on their disease status. The ratios of total T cells, helper T cells, cytotoxic T cells, natural killer cells, regulatory T cells, and monocyte subtypes were measured using flow cytometry. In addition, age, complete blood count for leukocyte, lymphocyte, neutrophil, and eosinophil counts, and the smoking status of all volunteers were evaluated. RESULTS: A total of 33 volunteers, including 11 patients with active IGM, 10 patients with remission IGM, and 12 healthy volunteers, were included in the study. The neutrophil, eosinophil, neutrophil/lymphocyte, and non-classical monocyte values were significantly higher in IGM patients than in healthy volunteers. Additionally, the CD4+ CD25+ CD127- regulatory T cell was significantly lower in IGM patients than in healthy volunteers. Furthermore, neutrophil, neutrophil/lymphocyte ratio, CD4+ CD25+ CD127- regulatory T cells, and non-classical monocytes showed significant differences when IGM patients were divided into active and remission groups. IGM patients had higher smoking rates, but this was not statistically significant. CONCLUSION: The changes in many cell types evaluated in our study were similar to the cell profiles of some autoimmune diseases. This could provide minor evidence to suggest that IGM is an autoimmune granulomatous disease with a local course.

Hemogram index parameters in the evaluation of male breast cancer and inflammatory response: a case-control study.

OBJECTIVE: Our aim was to investigate the hemogram index parameters and their clinical significance in the evaluation of the inflammatory response of patients with male breast cancer, who are rarely observed in the literature. METHODS: In total, 22 (n=22) healthy male and 28 (n=28) male breast cancer patients without synchronous/metachronous tumors were included in this study. They were grouped as the healthy male control group (Group 1) and the male breast cancer patient group (Group 2). The male breast cancer was divided into two subgroups, namely, early stage [(stage: 0/I/II) (Group 2A)] and late stage [(stage: III/IV) (Group 2B)], and their hemogram index parameters were compared. RESULTS: A significant (p>0.05) increase was observed in neutrophil/lymphocyte ratio (NLR) and·platelet/lymphocyte ratio (PLR) values in the late stage (Group 2B: stage III/IV) compared to the early stage (Group 2A: stage 0/I/II) and healthy control (Group 1) groups. CONCLUSIONS: In male breast cancer patients, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio values were significantly higher as the stage of cancer increased. These readily available simple tests can be used to evaluate the host's inflammatory response in male breast cancer.

Does focal heterogeneity affect survival in postoperative ipsilateral multifocal and multicentric breast cancers?

OBJECTIVE: In multicentric/multifocal breast tumors, there may be immunological and histological differences between foci that may affect survival and treatment choice. We aimed to evaluate the effect of focal heterogeneity seen in multicentric/multifocal breast tumors on survival. METHODS: We retrospectively collected and analyzed the clinicopathological data of 89 female patients with multifocal/multicentric breast cancer, whose surgical and medical treatment was completed and who were followed up for 5 years. RESULTS: Of all patients, 29.2% (26/89) were heterogeneous. Heterogeneity of these foci was as follows: histologic heterogeneity of index foci (mix type): 15.7% (14/89), histologic heterogeneity of inter-foci: 7.9% (7/89), and immunohistochemical heterogeneity of inter-foci: 10.1% (9/89). When additional foci were evaluated, oncological therapy was changed for 3 (3.3%) of 89 patients. Heterogeneity does not have a significant (p>0.05) effect on recurrence and survival in multicentric/multifocal breast cancers. Pathological N stage is an independent risk factor for disease-free survival (hazard ratio=2.29, 95% confidence interval=1.39-3.76, p=0.001). CONCLUSIONS: In multifocal/multicentric breast cancers, less than 4% of patients may experience heterogeneity requiring change in the therapeutic decision. However, heterogeneity does not have a significant effect on recurrence and survival in multifocal/multicentric breast cancers. The pathological N stage is an independent risk factor for disease-free survival.

Prognostic significance of the neutrophil to lymphocyte ratio in patients with curative resection of esophageal cancer. A single center experience.

AIM: In this study, we aimed to determine the clinical value and prognostic significance of the Neutrophil / Lymphocyte Ratio in patients undergoing curative surgery due to esophageal cancer. MATERIAL AND METHOD: Patients who underwent curative resection for esophageal cancer between 2015-2019 were included in the study. Two groups, Group1 (low NLR) and Group2 (high NLR), were created. Demographic and clinical features, intraoperative and postoperative results, tumor characteristics and mean survival were compared in the groups. RESULTS: A total of 48 patients participated in our study. Group 1 consisted of 18 patients and Group 2 consisted of 30 patients. Male sex was dominant in both groups (66.7% vs 73.3%, p. 0.431). Preoperative CEA was higher in Group 2 (3.97 vs 9.57, p. 0.032). Tumor diameter was larger in Group2 (3.33 vs 5.40 cm, p. 0.000). Adenocarcinoma was higher in Group 2 (33% vs 53.3%, p. 0.047), while squamous cell carcinoma was higher in Group 1 (66.7% vs 33.3%, p. 0.047). Lymph node positivity was higher in Group 2 (66.7% vs 93.3%, p. 0.024). The anastomosis leak was higher in Group 2 (0% vs 20%, p. 0.048). Postoperative hospital stay was longer in Group 2 (13.27 vs 23.9 days, p. 0.009). 90-day readmission was higher in Group1 (33.3% vs 3.3%, p. 0.008). Survival duration was shorter in Group 2 (29 vs 15 months, p. 0.005). CONCLUSION: This study revealed that preoperative high NLR was associated with poor survival, along with greater tumor diameter, increased lymph node metastasis rate, and increased anastomosis leakage in patients with esophageal cancer. These results suggest that modifying inflammatory responses and modulating the immune system may improve survival outcomes in patients with esophageal cancer. KEY WORDS: Esophagus cancer, Neutrophil/lymphocyte ratio, Preoperative neutrophil/lymphocyte ratio, Prognosis.

The prognostic value of Tumor Volume Index in patients with esophageal cancer who had curative resection A single center experience.

AIM: We aim to evaluate the prognostic significance of tumor volume in esophageal cancer. METHODS: Patients who underwent curative resection due to esophageal cancer between the years 2015 and 2019 were included in the study. The Tumor Depth Parameter (TDP) was defined as mucosa and submucosa =1, muscularis propria =2, adventitia =3, and invasion into adjacent organs=4. The Tumor Volume Index (TVI) was defined as the major axis X the minor axis X TDP. Two groups were formed based on TVI: Group 1 (low TVI) and Group 2 (high TVI). In the groups; patients were compared in terms of demographic and clinical features, intraoperative and postoperative outcomes, characteristics of the tumor and average survival. RESULTS: The patients were divided into two groups based on the cut-off value of 4,000. Group 1 (low TVI) consisted of 16 patients and Group 2 (high TVI) consisted of 28 patients. Male sex ratio was higher in Group 2 (50% vs 85%, p:0.011) Tumor diameter was observed to be larger in Group 2 (3.06 vs 5.54, p:0.000). Adenocarcinoma histologic type was more common in Group 2 (25% vs 64.3%, p:0.012). Incidence of respiratory complications was higher in Group 2 (0% vs 35.7%, p:0.024),Survival time (months) was shorter in Group 2 (36 vs 11, p:0.005). TVI's being over 4000 (HR)(95%-Confidence Interval ((Cl) 0.057 (0.011-0.311),p:0.001) was an independent risk factor to determine the rate of survival. CONCLUSION: TVI can be used as a prognostic factor in patients with esophageal cancer who underwent surgical therapy. TVI is closely associated with tumor histology and postoperative outcomes.

Application of crystal-line phenol in pilonidal sinus disease A single-center and single-surgeon experience.

AIM: Various surgical and minimally invasive treatment options are available in the treatment of pilonidal sinus. In our study, we aimed to retrospectively analyze the results of crystalline phenol application in patients who applied to our clinic with pilonidal sinus. MATERIAL AND METHOD: Patients who were applied crystalline phenol due to pilonidal sinus disease between 2018- 2019 were included in the study. The patients were evaluated in terms of demographic characteristics, pit count, surgical treatment history, abscess drainage history, number of repeated applications, complication status, recovery rate in the first month, success rate in the first year, and recurrence. RESULTS: 209 patients participated in our study. The average age of patients was 25.5, and the number of male patients was 4 times that of women. The patients had an average of 2.13 pits. Twenty-two patients had a history of abscess drainage. Thirteen patients had a history of surgical treatment. The recovery rate was 89.3% in the 1-month controls and 93.7% in the 1-year controls. Repeated application was performed to 11% of the patients. Seventeen patients had recurrence after wound healing. The most common complications were skin burn (1.4%) and wound infection (1.4%). CONCLUSION: In the treatment of pilonidal sinus disease, crystalline phenol can be safely applied with a high success rate, low recurrence rate and an acceptable percentage of complications. KEY WORDS: Crystalline phenol application recurrence, Pilonidal sinus, Minimally invasive.

Effects of bradykinin preconditioning in an experimental intestinal ischemia reperfusion model on rats.

PURPOSE: To investigate the effects of bradykinin on reperfusion injury in an experimental intestinal ischemia reperfusion model. METHODS: We used 32 Wistar-Albino rats. We composed 4 groups each containing 8 rats. Rats in sham group were sacrified at 100 minutes observation after laparotomy. Thirty minutes reperfusion was performed following 50 minutes ischaemia in control group after observing 20 minutes. Ischaemic preconditioning was performed in one group of the study. We performed the other study group pharmacologic preconditioning by infusional administration of 10 µg/kg/minute bradykinin intravenously. We sacrified all of the rats by taking blood samples to evaluate the lactate and lactate dehydrogenase (LDH) after resection of jejunum for detecting tissue myeloperoxidase (MPO) activity. RESULTS: Lactate and LDH levels were significantly higher in control and study groups than the sham group (P<0.001). There is no difference between the study groups statistically. (P>0.05). The results were the same for MPO levels. Although definitive cell damage was determinated in the control group by hystopatological evaluation, the damage in the study groups observed was lower in different levels. However, there was no significant difference between the study groups statistically (P>0.05). CONCLUSION: Either ischeamic preconditioning or pharmacologic preconditioning made by bradykinin reduced the ischemia reperfusion injury at jejunum.

Ectopic adrenal tissue in a hernia sac in an adult. A case report.

The discovery of ectopic adrenal tissue in the hernial sac is very rare, and in the majority of reported cases it is in children, while it is never described in adult subjects. This could be due to a progressive previous atrophy of the ectopic tissue or to an insufficient examination of the sac removed surgically. The most frequent site of these ectopias is the kidney, adjacent to the adrenal glands. The presence of ectopic adrenal tissue is important because of its neoplastic and hyperplastic potential. We report a case of a 69-year-old male patient who underwent a surgical operation of a left inguinal hernia and that the presence of ectopic adrenal tissue was reported in the pathologist's report. Preoperative abdominal ultrasound should therefore be performed in patients destined for an inguinal hernia surgery, because also the rare existence of ectopic adrenal tissue in the hernial sac should be kept in mind. KEY WORDS: Adrenal, Adult, Ectopia, Herni sac.

Postoperative surgical margin results of the phyllodes tumors from a tertiary hospital

SUMMARY OBJECTIVE: Phyllodes tumors in the breast are exceptionally uncommon fibroepithelial tumors. In the literature, they are typically categorized as benign phyllodes tumor, borderline phyllodes tumor, and malignant phyllodes tumor. This study aims to assess and present the clinical and surgical outcomes of patients diagnosed with phyllodes tumor. METHODS: The outcomes of patients aged 18 years and above diagnosed with phyllodes tumor between 2006 and 2023 were retrospectively reviewed. Patients were grouped as benign phyllodes tumor and borderline/malignant phyllodes tumor and compared by clinical and surgical results. RESULTS: Of all 57 patients with phyllodes tumor, 64.9% (n=37) were benign phyllodes tumor and 35.1% (n=20) were borderline/malignant phyllodes tumor [22.8% (n=13) borderline phyllodes tumor and 12.3% (n=7) malignant phyllodes tumor]. When the patients were divided into two groups as benign phyllodes tumor and borderline/malignant phyllodes tumor and compared, our cumulative (total) recurrence rate was 14.0%, with final surgical margin width between groups [(0<final surgical margin<2 mm vs final surgical margin≥2 mm) (p=0.154)] and recurrence [(8.1% benign phyllodes tumor vs 25.0% borderline/malignant phyllodes tumor) (p=0.080)]; there was no significant difference between our rates. CONCLUSION: Phyllodes tumors of the breast can be followed up with a narrow negative surgical margin (0 mm<final surgical margin<2 mm). However, after the initial surgery, re-excision is recommended for positive margins, while a wider surgical margin (≥10 mm) is not necessary for excision.

Role of Alvarado score and biological indicators of C-reactive protein, procalicitonin and neopterin in diagnosis of acute appendicitis.

BACKGROUND: The determination of a definitive preoperative diagnosis of acute appendicitis (AA) remains a challenge; however, delays in diagnosis increase complication rates. The aim of this study was to investigate the contribution of the Alvarado score (AS) alone and the AS combined with the use of the biological indicators of C-reactive protein (CRP), procalcitonin (PCT) and neopterin (NP) in the diagnosis. METHODS: Serum was collected from 100 patients who were admitted to the general surgery clinic of Istanbul University, Cerrahpasa Medical Faculty between March 4, 2014 and July 29, 2015 with the pre-diagnosis of AA and who agreed to take part in the study. The serum samples were stored at -70°C. The patients were divided into 2 groups: AA-positive (n=60) and AA-negative (n=40). The AA positive group was divided into subgroups of complicated (n=11), uncomplicated AA (n=49) and the AS, CRP, PCT, NP levels were compared. RESULTS: The study population consisted of 45 men (45%) and 55 women (55%), with a mean age of 32.8+-13.7 years (range: 18-92 years). There was no significant difference between the groups in age and gender. There were 24 patients with an AS ≤4 (3 had surgery), 35 patients with an AS of 5-7 (22 had surgery), and 41 patients with an AS of 8-10 (38 had surgery). Three of the 63 patients who underwent surgery were diagnosed with a normal appendix. The serum CRP, PCT, and NP measures were found to be inadequate to make an AA diagnosis alone, these values increased the sensitivity and specificity of the AS. The biological indicators were also significant in differentiating between the complicated and uncomplicated AA groups (p<0.05). CONCLUSION: Although the AS is useful, additional testing and clinical approaches are valuable to inform the diagnostic procedure. When considered alone, serum CRP, PCT and NP values are insufficient for a diagnosis of AA. However, they increased the diagnostic value of the AS and can be helpful in distinguishing complicated AA cases.

Predictors of recurrence in breast cancer patients with pathological partial response

SUMMARY OBJECTIVE: Patients with residual disease after neoadjuvant chemotherapy have a relative risk of developing recurrence. This study investigates the risk factors for recurrence in locally advanced breast cancer patients with residual disease and evaluates survival analysis. METHODS: This is a retrospective, single-center study. Breast cancer patients who failed to achieve a pathological complete response after neoadjuvant chemotherapy were included. Demographic, clinicopathological, and treatment characteristics were evaluated to identify predictive factors of recurrence and survival analysis. RESULTS: We included 205 patients in this study. After a median of 31 months of follow-up, 10 patients died, and 20 developed distant metastasis. Disease-free survival and disease-specific survival were 73.8% and 83.1%, respectively. Lymphovascular invasion and non-luminal subtype were independent predictors of locoregional recurrence. In situ carcinoma, lymphovascular invasion, ypTIII stage, and non-luminal molecular subtypes were independent predictors of disease-free survival. The only independent factor affecting disease-specific survival was cNII-III. The number of involved lymph nodes was an independent predictor of disease-free survival in patients without complete axillary response. CONCLUSION: Factors affecting disease-specific survival and disease-free survival were cNII-III and the number of involved lymph nodes, respectively. Patients with non-luminal, large residual tumors with in situ carcinoma, lymphovascular invasion, clinically positive axilla, and residual nodal involvement have a high relative risk for recurrence and may benefit from additional treatments.

Foreign body: A sewing needle migrating from the gastrointestinal tract to pancreas.

Of all ingested foreign bodies, 2.4% comprise of sewing needles. Through perforation of gastrointestinal tract, which occurs in 1% of cases, they can migrate into the liver and pancreas. Foreign bodies in pancreas should be considered in the differential diagnosis of chronic abdominal pain. Computed tomography scans provide valuable information for the localization of the lesion, which guide the surgeon during the operation. Secondary to foreign bodies that migrate to the pancreas, complications with high mortality such as pancreatitis, pseudoaneurysm, and pancreas abscess can be seen. Thus, for this patient group, diagnostic laparoscopy is recommended, considering its advantages of decreased postoperative pain, decreased wound infection, and faster recovery time. Here we present a case of a 23-year-old female patient, from whom an ingested needle that migrated from the back wall of the stomach to the pancreas was extracted by laparoscopic surgery.

Rare case of bilateral incarcerated obturator hernia: a case report.

Here, we report the case of an 84-year-old woman with acute mechanical intestinal obstruction (AMIO) who was admitted to our Emergency Department. Computed tomography (CT) scan revealed an incarcerated bilateral obturator hernia, and the defect was resolved using transabdominal preperitoneal (TAPP) technique with polypropylene mesh. The patient was administered an oral regimen two days after the operation. The patient stayed in the intensive care unit for 4 days and was uneventfully discharged on the 9th postoperative day. Follow-up was scheduled at the 6th month, during which no adverse events were detected and the patient did not report any complaints. Obturator hernia is among the differential diagnoses of intestinal obstruction requiring early diagnosis and prompt surgical intervention. Laparoscopic approach is less invasive compared with open surgery, and it can be attempted in cases presenting with no sign of ischemia or peritonitis. TAPP technique should be preferred since it allows the control of all intraabdominal pathologies and the viability of the intestines.

Extraction of a Foreign Body from the Breast Using Radio-guided Occult Lesion Localization (ROLL): Metallic Foreign Body in the Breast.

The most common clinical causes of metallic foreign body in the breast are surgical clips, pieces of guide-wire and gunshot wounds. Metallic foreign bodies can lead to local breast pain, abscesses, pneumothorax after granulomas or migration, and cardiac tamponade. Mammotome biopsy, fluoroscopy, guide-wire biopsy and radio-guided occult lesion localization (ROLL) are the standard techniques applied for surgical excision of non-palpable breast lesions. This article presents the second case in the literature undergoing the ROLL technique for the removal of a metallic foreign body from the breast.
