The Relationship Between Serum Lipids and the Formation of Colorectal Polyps.

BACKGROUND AND AIMS: Obesity, metabolic syndrome, and hyperlipidemia are known as risk factors for colorectal tumors. Colorectal polyps are accepted as potential precursors of colorectal cancer (CRC). This study was designed to clarify the association between the levels of serum lipids and the presence of colorectal polyps. METHODS: This study was conducted at Basaksehir Cam and Sakura City Hospital, Gastroenterological Surgery Clinic, Istanbul, Turkey. We retrospectively analyzed patients who underwent colonoscopy with serum lipid profile within one month for a one-year period. Groups were analyzed in terms of the correlation between hyperlipidemia and the formation of polyps. The study group was also evaluated in terms of the polyp type, localization, and number. RESULTS: Among 453 patients, females were 248 and males were 211, with a mean age of 56.7. The study and control groups involved 259 and 194 patients, respectively. The age and serum levels of low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglyceride (TG) were found to be statistically significant in terms of polyp presence and number (p < 0.05). CONCLUSION: Colorectal polyps are well-known precursors of CRC. We found that the combination of elevated serum levels of low-density lipoprotein cholesterol, total cholesterol, and triglycerides may be a risk predictor for the presence of colorectal polyps, which can be advantageous in cancer screening.

Colonoscopy following the positron emission tomography/computed tomography scan in patients with incidental colorectal uptake: what is the most effective management?

OBJECTIVE: Colorectal cancer is one of the most common malignancies. Survival rates are directly related to the stage of cancer at the time of diagnosis, emphasizing the value of early diagnosis. Positron emission tomography with 18F-fluorodeoxyglucose is the gold standard imaging technique in staging, monitoring after treatment, and follow-up. We aimed to assess the importance of incidental 18F-fluorodeoxyglucose uptake by colon and rectum in positron emission tomography-computed tomography imaging to determine a significant cutoff value for further investigation using colonoscopy and histopathological assessment. METHODS: We performed a retrospective analysis of patients with both 18F-fluorodeoxyglucose-positron emission tomography/computed tomography scan and colonoscopy during 1 year and included the cases who had undergone a colonoscopy within 3 months following the positron emission tomography/computed tomography scan due to an incidental positive finding. Patients with a diagnosed colorectal malignancy or with a history of previous colorectal operations were excluded. RESULTS: A total of 81 patients were included in this study. Among 81 colonoscopic evaluations, histopathology revealed malignancy in 8 patients, and the prevalence of incidental colorectal cancer 18F-fluorodeoxyglucose uptake was found to be 9.87%. SUVmax was found to be significantly related to malignancy and other colonoscopic findings (p<0.001). SUVmax cutoff value to suggest colorectal cancer was found to be median [7.9 (4.1-12.7)] (p<0.001). CONCLUSION: Regarding the studies determining a significant cutoff value, incidental colonic 18F-fluorodeoxyglucose uptake on positron emission tomography/computed tomography should lead the clinician to further investigation with colonoscopic biopsy, although the cutoff values for SUVmax are not certain and different in almost every published study, and negative positron emission tomography.computed tomography findings should not completely rule out malignancy, especially in high-risk patients.

Congenital diaphragmatic hernia with gastric perforation in adult: Intrathoracic gastric perforation.

Congenital diaphragmatic hernias are rarely seen and they are usually diagnosed in the neonatal period. Congenital diaphragmatic de-fect, also known as Bochdalek hernia, usually occurs with the persistence of the pleuroperitoneal canal in the left posterolateral region of the diaphragm in the embryological period. Although it is rarely seen in the adults, conditions such as intestinal volvulus, strangulation, or perforation with congenital diaphragm defect progress with high mortality and morbidity. In this study, we reported our case that we operated for intrathoracic gastric perforation with congenital diaphragmatic defect. When the patient admitted to the hospital, he had an atypical abdominal pain, significant back pain, and suspicious respiratory complaints. Radiological imaging showed that the stomach and the spleen were located in the left hemithorax due to diaphragmatic hernia also stomach was very dilated. Tachycardia, hypotension, and low saturation developed on the 2nd day of the patient's hospitalization. In the control imaging of the patient, in the left hemithorax, stomach was collapsed and the surrounding appearance compatible with hydropneumothorax, after that findings emergency laparotomy was decided. During the operation, as demonstrated by the radiological findings, a diaphragm defect was seen in the left posterolateral region of the diaphragm. The stomach and spleen were herniated to the left hemithorax from this defect. The stomach and spleen were reduced into the abdomen. The left hemithorax was lavaged with 2000 cc isotonic, left tube thoracostomy was applied, and the diaphragm was repaired. The anterior stomach was primarily repaired. In post-operative follow-up, there were no complications other than wound infection and thoracic tube of the patient was removed. The patient who tolerated enteral food was discharged from hospital with full recovery.

The Importance of Mapping Vagus and Laryngeal Nerves Monitoring During Thyroid Surgery.

OBJECTIVE: To determine the location of thyroid-related nerves by nerve monitoring and demonstrate the usefulness of Nerve Integrity Monitor in thyroid surgery. STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of General Surgery, University of Health Sciences, Istanbul Training and Research Hospital, Turkey, from February 2017 to January 2020. METHODOLOGY: Patients, who underwent thyroid surgery, were evaluated for age, gender, preoperative diagnosis, type of surgery, histopathological result, postoperative hoarseness, and postoperative vocal cord examinations. The vagus nerve, recurrent laryngeal nerve (RLN), and superior laryngeal nerve (SLN) were mapped by nerve monitoring. RESULTS: A total of 328 patients were included in this study. On both sides, the vagus nerve was most often located in the posterior of the internal carotid artery and internal jugular vein and less frequently anterior to this vein. A total of 303 right RLNs and 305 left RLNs were verified. The SLN was visualised or motor activity was verified by nerve monitoring on the right side in 181 patients and on the left side in 179 patients. The SLN's location was classified most frequently as type I and least frequently as type IIb on the right and left sides. CONCLUSION: The reported variations, the experience of the surgeon, and these anatomical markers cannot be adequate in preventing nerve injuries. Furthermore, the variations can be identified more clearly peroperatively with the use of nerve monitoring. KEY WORDS: Laryngeal nerves, Nerve mapping, Nerve monitoring, Nervus vagus, Thyroid surgery, Zuckerkandl tubercles.

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.

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

SUMMARY 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.

Number of cells in parathyroid tissue in primary hyperparathyroidism cases and its relationship with serum calcium value.

BACKGROUND: The relationship between serum calcium (Ca) level to serum parathyroid hormone (PTH), phosphorus (P) levels and tissue properties of the parathyroid gland is unknown in primary hyperparathyroidism cases. Revealing this relationship may be useful for understanding the etiopathogenesis of primary hyperparathyroidism and determining the time of treatment. METHODS: Ninety patients (71 females, 19 males, age range; 27-73 years, average age; 46) who underwent single gland excision with the diagnosis of primary hyperparathyroidism were studied. The patients were divided into 2 groups as serum Ca level <12 and serum Ca level ≥12. Age and sex of the patients, mean cell number of the gland, mean volume of the gland, serum levels of PTH, P, and histopathologic type of hyperplasia were evaluated. RESULTS: The mean cell number per cubic centimeter is 22.9 (10-220 range) million in all glands. Serum Ca level was <12 in 82 (91.1%) of the patients, and ≥12 in 8 (8.9%) cases. Mean cell number of the gland, mean volume of the gland, existence of cystic hyperplasia of the gland, serum levels of PTH and P were statistically significant between the 2 groups (P < .001, P < .001, P < .05, P < .001, P < .05 respectively). CONCLUSION: In primary hyperparathyroidism cases serum Ca level is not related to age and sex but directly related to proportionals to the cell number and volume of the gland and serum levels of PTH, inversely related to cystic hyperplasia and serum levels of P. Early surgical intervention should be planned since the serum Ca level will be high in large adenomas with a noncystic radiological appearance.

The effect of mutation status, pathological features and tumor location on prognosis in patients with colorectal cancer.

OBJECTIVE: Colorectal cancer is the most common malignancy of the gastrointestinal tract. It is the third most common tumor in both genders and the second reason of cancer-related deaths. In recent years, tumor location has gained importance as a prognostic indicator. In this study, we aimed to analyze if there was a prognostic effect of tumor location, the pathological features, and the mutation status of patients on survival. METHODS: Two-hundred and ten colorectal cancer patients aged 18 years and older were included into the study. One-hundred and forty-two patients had left-sided tumor and 68 patients had right-sided tumor. Patients who had other malignancies rather than squamous cell skin cancer and in situ cervical cancer were excluded. All statistical tests were carried out using two-sided process, and a p≤0.05 was considered statistically significant. RESULTS: There were 140 men and 70 women in the study. The median age of the patients was 62 years old. There was no statistically significant difference according to tumor location and survival of patients. The overall survival of patients with right-sided tumors was 60.5 months and 47.2 months for left-sided tumors. Disease-free survival of patients was 63.7 months for right-sided tumors and 46 months for left-sided ones. Perineural invasion, grade and stage were crucial prognostic parameters. Disease-free survival was longer for female colorectal cancer patients. CONCLUSION: According to our study, survival of patients was similar regardless of tumor location. This can be explained by the different sequencing of treatment strategies and divergent population genetics.

A 4-year single-center experience in the management of esophageal perforation.

BACKGROUND: Esophageal perforation (EP) is a lethal surgical emergency that needs to be diagnosed and treated immediately. Diagnosis and treatment options for EP are limited due to its lower incidence. There are scoring systems proposed for this purpose; however, they cannot be applied to every patient. The recent trend in the treatment of EP is toward the non-operative approach over the surgical treatment methods. The purpose of the present study was to evaluate our treatment methods and outcomes in patients with EP. METHODS: Thirteen patients with EP treated in our clinic between 2013 and 2017 were retrospectively reviewed. The Pittsburgh Perforation Severity Score (PSS), systemic condition status, and Clavien-Dindo Classification (CDC) score were assessed, and treatment methods were reviewed. Their effects on morbidity and mortality were examined using Fisher's exact test and biserial correlation test. RESULTS: A total of 13 patients (six males and seven females; median age 64 years) were included in the study. Ten patients were managed non-operative, and three were treated surgically. Of the 10 patients, two had additional surgery after non-operative management. The PSS, systemic condition status, CDC score, duration of stay in the hospital, time to diagnosis, presence of hypotension, and being in shock were strongly correlated with mortality (p<0.05). The PSS, CDC score, and stay in the intensive care unit were strongly correlated with morbidity (p<0.05). The comparison between the non-operative and operative groups did not yield a statistically significant difference in mortality and morbidity. CONCLUSION: Even if the scoring systems help to understand the severity of the condition, they are inadequate to determine the treatment option. Early diagnosis and treatment are the most important steps in management. Operative and non-operative treatment options are not superior to each other, but their complementary use will be more beneficial for the patients.

Is intraoperative nerve monitoring useful for surgical training in thyroid surgery?

OBJECTIVES: Parathyroid glands and recurrent laryngeal nerves (RLNs) are at risk during thyroid surgery. However, the identification of the nerves has reduced these risks. Intraoperative nerve monitoring (IONM) during thyroid surgery has gained widespread acceptance as an aid to the gold standard of visually identifying the RLN. The aim of the present study was to evaluate the effect of the identification of the RLN during thyroidectomy by using IONM. MATERIAL AND METHODS: Seven hundred forty-eight patients were included in our prospectively designed study. Of these 748 patients, 1496 nerves at risk were studied. Group 1 consisted of 736 nerves that were identified using IONM, whereas Group 2 consisted of 760 visually identified nerves. RESULTS: In the non-IONM group, the rate of temporary nerve palsy was lower in patients operated by experienced surgeons than in patients operated by residents (p= 0.001). In the IONM group, RLN injury rates were similar between experienced surgeons and residents. CONCLUSION: In spite of the fact that the duration of the operation was lower with IONM, the abbreviated duration may not appear to have clinical significance. The main advantage is for less experienced surgeons. IONM significantly decreases RLN palsy rates of the surgeons with limited experience in thyroid surgery.

Morgagni's Hernia: Analysis of 21 Patients with Our Clinical Experience in Diagnosis and Treatment.

A Morgagni's hernia is a congenital defect found in the anterior aspect of the diaphragm between the costal and the sternal portions of this muscle. This defect is also referred to as the space of Larrey. It has been reported that 70% of patients with Morgagni's hernia are female, 90% of the hernias are right-sided, and 92% of the hernias have hernia sacs. This type of hernia is a rare clinical entity and accounts for 3% of all surgically treated diaphragmatic hernias. There are no large retrospective or prospective studies on this topic. This type of hernia is a rare type among adults without a well-described prevalence and without well-established definitive management strategies. There are also few clinical reports about this clinical entity and its surgical treatment. We treated 21 patients with Morgagni's hernia in a 12-year period, and we report our experience while discussing the surgical treatment of this disease. We performed a retrospective review of the 21 patients who were operated between 2003 and 2015. These patients had undergone surgical repair of Morgagni's hernia. For each subject, demographic data, symptoms of presentation, physical examination findings, preoperative imaging studies and diagnosis, and surgical procedures were documented. Location of the hernia sac and its contents, postoperative complications, and duration of hospital stay were recorded and evaluated. Twelve patients were females and nine were males. The mean age of patients was 63.85 years. Dyspnea was the most prominent symptom in our patients. Morgagni's hernias were located on the right side in 19 patients and on the left side in 2 patients. Chest X-ray in 10 patients and abdominal computerized tomography in 17 patients were the major diagnostic tools. Four patients were operated as emergency while others underwent elective surgery (17 patients). Twelve patients were operated with laparoscopy and the remaining nine were operated with the conventional open abdominal technique. Hernia sacs were observed in all of the patients and removed except in four of them. The omentum and the transverse colon were the most commonly seen organs in hernia sacs. Hernia defects were repaired with primary sutures in four patients (all open cases) and primary closure supported with mesh in six patients (four laparoscopic, two open cases). In the remaining 11 patients, hernia defects were closed with synthetic meshes (eight laparoscopic, three open cases). Mean postoperative hospital stay was 9.8 days. No recurrence was observed in any patients. Only one of our patients died during follow-up. In Morgagni's hernias, surgical intervention is necessary as the hernia may cause complications such as strangulation of the colon or intestines. A laparoscopic approach has increased its popularity in recent years because of the well-known advantages of laparoscopy.

Clinicopathological features of gastroenteropancreatic neuroendocrine tumors: A retrospective evaluation of 42 cases.

OBJECTIVE: Neuroendocrine tumors arise from neuroendocrine cells in any part of the body; approximately two thirds of these tumors are located in the gastrointestinal tract and pancreas. Although gastroenteropancreatic neuroendocrine tumors are known as rare neoplasms, their prevalence has recently increased due to advanced diagnostic methods and increased awareness of the disorder. In the present study, we aimed to review patients who were treated and followed up for gastroenteropancreatic neuroendocrine tumors at our clinic in terms of clinical picture, pathological findings, and prognosis. MATERIAL AND METHODS: Data from 42 patients diagnosed with gastroenteropancreatic neuroendocrine tumors who were treated and followed up at our Training and Research Hospital from August 2011 to December 2015 were retrospectively evaluated. RESULTS: A total of 42 patients aged 17-81 years (mean age 46.9 years) were enrolled in the study. The most common symptom was abdominal pain, which was seen in 31 (73.8%) patients. gastroenteropancreatic neuroendocrine tumors were detected in the stomach (n=5, 35.7%), appendix (n=11, 26.2%), rectum (n=6, 14.3%), pancreas (n=4, 9.5%), ileum and colon (n=2, 4.8%), and duodenum and jejunum (n=1, 2.4%). Local excision was performed in seven (16.7%) patients. Nine (21.4%) patients underwent gastric wedge resections, either by a laparoscopic procedure (n=3) or by open surgery (n=6). Total gastrectomy and laparoscopic subtotal gastrectomy were performed on three (7.1%) patients and two patients (4.8%), respectively. After the surgical procedures, the patients were followed up for a mean period of 36 months (15-57 months); the one-year and three-year survival rates were determined to be 100% and 97.6%, respectively. CONCLUSION: Management of gastroenteropancreatic neuroendocrine tumors requires accumulation of knowledge and experience to establish a standardized approach. Therefore, we believe that collecting regular national data from these cases in every country will contribute to understanding the details of this entity worldwide.

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.

Laparoscopic Treatment of Adrenal Tumors: A Single-Center Experience with 58 Patients.

Background. The aim of this study is to discuss the laparoscopic approach and assess the immunohistochemical expression profiles of synaptophysin, Ki-67, and inhibin and patient outcomes in adrenal masses through a series of cases treated at our institution. Method. The study was conducted on 58 patients who were diagnosed with adrenal masses. All cases were operated on laparoscopically for adrenal masses. Results. Both inhibin and synaptophysin were found positive in 45 patients (77,6%). Ki-67 was negative in 11 patients, whereas it was found positive in 42 with a rate of 1%. The size of the masses ranged from 1 up to 9 cm (mean 4,3 ± 1,5). Urine hormone excretion was measured within normal ranges in 47 out of 58 patients (81%). Most of the diagnosed patients were harboring Cortical Adenoma (n: 38; 65,5%). All of the masses were successfully resected without complication except 3 patients. Because of complications of bleeding, the operation was converted to open surgery for 2 patients. Conclusion. Morbidity, mortality, and healing were comparable, regardless of tumor size, yet involvement in both laparoscopic and adrenal surgery was required. Our results suggested that laparoscopic adrenalectomy should replace open surgery as the standard treatment for most adrenal masses.

Malignant Phyllodes Tumor Including Aneurysmal Bone Cyst-Like Areas in Pregnancy - a Case Report and Review of the Literature.

BACKGROUND: Malignant phyllodes tumors of the breast are rare biphasic neoplasms. Only few cases related to pregnancy have been reported. CASE REPORT: A 37-year-old woman presented with swelling and pain in her left breast as well as hyperemia on the breast skin, 4 weeks after labor. In her family history, her aunt and maternal cousin had had a breast cancer diagnosis. Clinical evaluation of the patient was consistent with a breast abscess. Therefore, abscess drainage and biopsy from the cavity wall were performed. However, the biopsy was diagnosed as malignant phyllodes tumor. An evaluation by ultrasonography showed a well-defined hypoechoic mass with many cystic spaces covering the entire breast tissue. Therefore, a simple mastectomy was performed. Microscopic examination revealed a high-grade malignant phyllodes tumor. Additionally, bone cyst-like areas in the form of sponge-like blood-filled non-endothelialized spaces were observed. CONCLUSIONS: Since the breasts become larger due to the physiological changes during pregnancy, any underlying breast lesions may be obscured. Therefore, clinical breast examination in the first visit of pregnancy is important.
