Lateral Lymph Node Dissection for Locally Advanced Rectal Carcinoma: A Step-by-Step Description of Surgical Anatomical Planes During Cadaveric Dissection and Minimally Invasive Surgery.

PURPOSE: Total mesorectal excision (TME) is accepted as gold standard method in rectal cancer globally. But there is no standard for lateral lymph nodes. Combination of neoadjuvant treatment plus lateral lymph node dissection (LLND) in select patients might be a promising method. Our purpose is to describe the anatomic landmarks of LLND on cadavers and minimally invasive surgery. MATERIALS AND METHODS: Local advanced rectal cancer and lateral lymph node (LLN) metastasis are accepted as an indication of neoadjuvant treatment. LLND was performed according to preoperative imaging after radiochemotherapy. RESULTS: Twenty-eight (10.5%) of 267 patients with rectal cancer who had suspected lateral lymph node metastasis (LLNM) with magnetic resonance imaging (MRI) underwent LLND in addition to TME after neoadjuvant chemoradiotherapy. Eight of them had LLNM. Three patients had bilateral LLND and only 1 had LLNM. The median number of harvested lymph nodes was 6. The rates of LLNM increased with the presence of poor prognosis markers. One regional and 1 distant recurrence were detected in patients who had no LLN metastasis compared with2 regional and 4 distant recurrences in the LLN-positive group. CONCLUSIONS: Local advanced rectal cancer cases may benefit from LLND, but it does not appear to have an effect on overall survival. There is no consensus whether size and/or morphologic criteria in MRI are the ideal guide for LLND.

Psychiatric Symptoms, Aggression, and Sexual Dysfunction Among Patients With Benign Anal Conditions.

INTRODUCTION: The aim of this study was to investigate the incidence of general psychiatric symptoms, aggression levels, and sexual dysfunction in patients with benign anorectal diseases and compare the results with those of healthy control subjects. METHODS: We prospectively enrolled consecutive adult patients who presented for treatment of benign perianal diseases and healthy control subjects between June 2017 and December 2018. All patients had either grade 3 or 4 hemorrhoidal disease or perianal fistula with active discharge who had not undergone previous anorectal surgery. We also included a control group with benign subcutaneous lumps presenting for minor surgery. We used the Symptom Checklist-90-Revised Form to evaluate general psychiatric symptoms, the Buss-Perry Aggression Questionnaire (BPAQ) to evaluate aggression levels, and the Arizona Sexual Experiences Scale to evaluate sexual dysfunction. RESULTS: A total of 563 patients were assessed for eligibility; after exclusions, 94 with anal fistula, 89 with hemorrhoids, and 59 healthy control subjects were enrolled. The groups were similar with regard to age, gender, and educational level. Physical and verbal aggression, anger, and total BPAQ score were significantly higher in patients with perianal fistula than in those with hemorrhoidal disease and healthy control subjects (P < .001). CONCLUSION: This study suggests that patients with perianal fistula have higher levels of aggression than healthy control subjects and those with hemorrhoidal disease. One must bear this in mind during preoperative patient evaluations and obtaining informed consent. Further studies are needed to investigate the reason for this association and potential causality.

Quality of life after colorectal surgery: A prospective study of patients compared with their spouses.

BACKGROUND: Although radical surgery for colorectal cancer improves the oncological outcomes, a significant portion of patients suffer from alterations in their quality of life (QoL). There are many studies investigating the QoL of patients who have colorectal cancer but none of these focus on the QoL of spouses. AIM: To compare the QoL of patients after colorectal surgery to the QoL of spouses. METHODS: This prospective study consisted of patients who were married and who underwent surgery at the University of Ankara, Department of Surgery between March 2006 and November 2010. Patients' spouses were also enrolled. The study was approved by the Ethics Committee of the Faculty of Medicine, Ankara University, and all patients provided written informed consent. The study included patients who underwent curative surgery for colorectal carcinoma [n = 100; abdominoperineal excision (n = 33), low anterior resection (n = 33), left hemicolectomy (n = 34)] and their spouses (n = 100). The patients and spouses completed the Medical Outcome Study 36-item Short Form Survey (SF-36) and the World Health Organization Disability Assessment Schedule II (WHODAS-II) preoperatively and at postoperative months 15 to 18. RESULTS: During this 4.5-year study period, 273 patients with sigmoid or rectal cancer were admitted to the hospital. Of these patients, 119 were eligible and willing to participate. Eleven patients had either systemic or locally inoperable disease, three patients had a severe surgical complication, and five patients were lost to follow-up. Therefore, a total of 100 patients completed the follow-up period. There was a statistically significant positive correlation between the disability scores of patients and the scores of their spouses for some of the WHODAS-II subscales, such as "self-care," "life activities," and "participation in society," as well as for the total WHODAS-II score. There was also a positive correlation between the QoL of patients and the QoL of their spouses in most of the SF-36 subscales. Statistically significant correlations were observed for the "bodily pain," "general health," "vitality," "social function," "emotion," "mental health," and mental component summary score subscales of the SF-36. When gender differences were evaluated, the QoL of male patients' spouses changed more when compared with female patients' spouses for all of the WHODAS-II subscales. Colorectal cancer surgery has a significant effect on the QoL of both patients and their spouses, these effects were more significant among male patients' spouses. CONCLUSION: Preoperative counseling regarding potential problems should therefore collectively address patient and their spouse as a couple rather than the patient alone, particularly for patients undergoing low anterior resection and abdominoperineal resection procedures.

Redefining the collateral system between the superior mesenteric artery and inferior mesenteric artery: a novel classification.

AIM: The aim of this study was to evaluate the arterial collateral vasculature between the superior mesenteric artery and the inferior mesenteric artery (IMA) from a surgical perspective. METHOD: A total of 107 fresh adult cadavers (94 male) were studied with emphasis on the vascular anatomy of the left colon. Dissections were carried out mimicking the anterior resection technique. The vasculature of the left mesocolon and the collaterals between the superior mesenteric artery and the IMA with respect to their relationship to the inferior mesenteric vein (IMV) were assessed and classified. Collaterals were classified into three different groups: marginal anastomoses (via the marginal = pericolic artery), intermediate mesocolic anastomoses (parallel to the marginal artery but neither adjacent to the IMV nor close to the duodenum) and central mesocolic anastomoses (next to the IMV at the level of the duodenojejunal junction and the lower border of the pancreas). RESULTS: All patients had a marginal anastomosis. However, the marginal anastomosis, as the only anastomosis between the superior and inferior mesenteric arteries at the splenic flexure, was observed in 41 cases (38%). In addition to the marginal artery, intermediate mesocolic anastomoses were found in 49 (46%) and a central mesocolic anastomosis was observed in 17 (16%) of the 107 cases in the splenic flexure mesocolon. It is in this latter variant that collateral vessels can be compromised during ligation/transection of the IMV. CONCLUSION: This new classification can contribute to a precise mesocolic dissection technique and splenic flexure mobilization and help prevent ischaemic damage to the descending colon.

Surgical Drains After Laparoscopic Donor Nephrectomy: Needed or Not?

BACKGROUND Routine placement of prophylactic drains after laparoscopic donor nephrectomy has been suggested and has become common practice in some centers. However, there is a lack of evidence proving the surgical benefits of routine drain placement in laparoscopic donor nephrectomy. Here, we assessed the effect of surgical drain placement on recovery, length of hospital stay, and complication rates of live kidney donors. MATERIAL AND METHODS This retrospective study included all live donor nephrectomies performed at a single institution from January 2010 to January 2017. Surgeries were performed by 2 surgeons; one routinely placed a closed suction drain after LDN whereas the other did not. Patients operated on by these 2 surgeons were enrolled in either the drain or no drain group. Demographic data, preoperative and postoperative creatinine levels, estimated blood loss (EBL), surgical time, surgical complications, and length of hospital stay were compared. RESULTS The study included 272 patients. Three were converted to open donor nephrectomy and were excluded (1.1%). Among the 269 patients, 156 (57.9%) had surgical drains and 113 (42.1%) did not. Mean surgical time, estimated blood loss, and duration of hospital stay did not significantly differ between groups. Postoperative complications were encountered in 17 of the patients, but the overall complication rate did not differ between patients with vs. those without surgical drains. CONCLUSIONS There was no significant difference between the drain and no drain groups in terms of length of hospital stay, complication rates, or postoperative creatinine levels. Thus, placement of a surgical drain in the setting of an LDN is not justified based on our single-center experience.

Live Donor Assessment Tool (LDAT): A Turkish validity and reliability study.

BACKGROUND/AIMS: Psychosocial and psychiatric evaluations are crucial components of the assessment of a live donor candidate. The Live Donor Assessment Tool (LDAT) was developed for this purpose. This study aims to evaluate the validity and reliability of the Turkish version of LDAT. MATERIALS AND METHODS: 132 live kidney or liver donor were referred to assess their psychosocial/psychiatric appropriateness for donation and were randomized for clinical evaluation as usual or with LDAT. The internal consistency of LDAT was measured by Chronbach's alpha coefficient. Inter-rater reliability was measured by using Spearman's correlation coefficient. The potential validity of LDAT was assessed by comparing LDAT scores to clinical decisions. The Mann-Whitney U test was used to compare LDAT scores across two clinically classified groups (acceptable/declined). Logistic regression was performed using LDAT scores to predict the clinical decision. RESULTS: The Turkish version of LDAT items demonstrate good internal consistency (α=0.773). Inter-rater reliability of LDAT demonstrated strong correlation (ICC=0.72). LDAT scores differentiated the accepted/declined groups, and strongly predicted the clinical decision. With a cut-off score of 60.5, LDAT was found to have high sensitivity and specificity. CONCLUSION: The Turkish version of LDAT was found to be a valid and reliable tool. LDAT could be an appropriate tool to assess live donor candidates.

Maintenance Immunosuppressive Treatment of Renal Transplant Recipients in the Critical Care Unit.

BACKGROUND: In intensive care unit (ICU), although there is no standard protocol for maintenance of immunosuppressive (IS) treatments for the kidney transplant recipients (KTx), the dose and the number of IS drugs are decreased according to the center's experience. The aim of this study is to evaluate the changes in IS treatment during stays in the ICU and to evaluate the safety and results of this modification on the IS treatment in the ICU arbitrarily. METHOD: We evaluated retrospectively our kidney transplant recipients in ICU between 2012 and 2017. The immunosuppressive protocols and the results were taken from the ICU documents. RESULTS: A total of 31 (18 male, 13 female) patients were suitable for the analysis. They were all under the triple IS protocol including Tacrolimus (Tac) + Mycophenolate mofetil (MMF) + steroid before the admission. The reason for ICU admission were severe sepsis in all patients. In ICU, 16 patients (51.6%) died, and a total of 10 patients were lost with functional graft. Change in IS treatment is as follows: a total of the 23 patients (74.2%) were given only steroids, and 8 patients (25.8%) were changed from triple to 2 drugs. Acute kidney injury developed in 42% (13 patients) of the patients in ICU. CONCLUSION: In our study, we observed that life-threatening severe infections were the main cause of ICU admission in KTx. Reduction in IS treatments are common practice, and reduction to a single dose of steroid was the most frequently chosen IS treatment. Eighty percent of patients are discharged with reduction of steroid gradually. None of the patients developed acute rejection and permanent graft injury.

Acute arterial occlusion due to vascular closure device: A report of two cases.

Vascular closure devices are frequently used after percutaneous arterial interventions to achieve hemostasis at the puncture site and facilitate early ambulation. Occasionally, complications have been reported with closure devices, such as hematoma, infection, arteriovenous fistula, pseudoaneurysm, and ischemia. This is a report of 2 cases of severe, acute-onset arterial occlusion and critical limb ischemia, one of which occurred in the upper limb following the use of a vascular closure device, and the required surgical treatment.

Omega-3 fatty acid supplementation does not influence liver regeneration in rats after partial hepatectomy.

AIM OF THE STUDY: In the initiation of liver regeneration, multiple stimulatory and inhibitory factors participate. In this study, we aimed to evaluate the effects of omega-3 fatty acids on liver regeneration after 30% partial hepatectomy in rats. MATERIAL AND METHODS: A total of 14 male Wistar Albino rats were included in this study. The animals were randomly allocated to two groups: the control group (n = 7) and the omega-3 group (n = 7). Rats in the control group were fed a standard rat chow and rats in the omega-3 group received 10 mg/kg/day omega-3 supplementation in addition to normal rat chow in the perioperative period. Rats were investigated seven days after 1/3 partial hepatectomy by liver weight change and hepatocyte proliferation. RESULTS: The mean liver regeneration rate was found to be slightly higher (p = 0.061) in the omega-3 group compared the control group. In addition, no significant difference was observed regarding binuclear hepatocyte ratio in pericentral and periportal areas between the two groups. However, livers from rats given omega-3 supplementation have less inflammatory cellular infiltrate in the portal space than livers from the control group. CONCLUSIONS: Supplementation with omega-3 fatty acids showed no influence on the liver regeneration in rats undergoing 1/3 partial hepatectomy.

Splenic hamartoma is a rare cause of abdominal pain: Case report and literature review.

Hamartoma is a rare benign tumor of the spleen. It is often asymptomatic and diagnosed incidentally. In this study, we report the case of a 51-year-old female patient who was admitted to our department for intermittent epigastric pain since the last 6 months and left upper quadrant fullness. She was diagnosed with splenic hamartoma histopathologically after splenectomy. Although splenic hamartoma is very rare, it must be included in the differential diagnosis of splenic mass-forming lesions.

Effects of Hysterectomy on Pelvic Floor Disorders: A Longitudinal Study.

BACKGROUND: Hysterectomy might adversely affect pelvic floor functions and result in many different symptoms, such as urinary and anal incontinence, obstructed defecation, and constipation. OBJECTIVE: The aim of this prospective study was to evaluate the influence of hysterectomy on pelvic floor disorders. DESIGN: This was a prospective and longitudinal study. SETTINGS: The study was conducted at the Ankara University Department of Surgery and the Dr Zekai Tahir Burak Women's Health Research and Education Hospital between September 2008 and March 2011. PATIENTS: The study was performed on patients who underwent hysterectomy for benign pathologies. MAIN OUTCOME MEASURES: A questionnaire about urinary incontinence (International Continence Society scoring), anal incontinence, constipation, and obstructed defecation (Rome criteria and constipation severity score), along with an extensive obstetric history, was administered preoperatively and postoperatively annually for 4 years. RESULTS: Patients (N = 327) who had completed each of the 4 annual postoperative follow-ups were included in this study. Compared with the preoperative observations, the occurrence of each symptom was significantly increased at each of the follow-up years (p < 0.001). Over the 4 postoperative years, the frequencies for constipation (n = 245) were 7.8%, 8.2%, 8.6%, and 5.3%; those for obstructed defecation (n = 269) were 4.5%, 5.2%, 4.1%, and 3.0%; those for anal incontinence (n = 252) were 4.8%, 6.3%, 6.0%, and 5.2%, and those for urinary incontinence (n = 99) were 12.1%, 12.1%, 11.1%, and 13.1%. In addition, patients who had no preoperative symptom (n = 70) from any of the selected symptoms showed a postoperative occurrence of at least 1 of these symptoms of 15.8%, 14.3%, 11.4%, and 8.6% for the postoperative years 1, 2, 3, and 4. LIMITATIONS: Although the study had several limitations, no comparison with a control population was the most important one. CONCLUSIONS: Hysterectomy for benign gynecologic pathologies had a significant negative impact on pelvic floor functions in patients who had no previous symptoms.

The effects of exercise on mastalgia.

OBJECTIVE: Mastalgia is often ignored by physicians although it is the most common breast-related complaint among women. The effectiveness of exercise therapy for mastalgia is unclear. The aim of this study is to investigate the effects of exercise on mastalgia. METHODS: A randomized controlled trial was conducted with twenty women with complaints of mastalgia fulfilling the inclusion and exclusion criteria. Patients were randomly assigned to the control group and to the exercise group. Sports brassiere, refraining from caffeine- and methylxanthine-containing foods, and simple analgesics were recommended for two groups. In the exercise group, an exercise program was conducted three times a week for 6 weeks. Participants in both groups were evaluated for breast pain and using the Short-Form Health Survey (SF-36) questionnaire before and six weeks after study. Serum cytokine levels were also collected and analyzed. RESULTS: No significant differences were detected with respect to age, body mass index, menopausal status, psychiatric condition, and existence of unexplained pain syndromes between the groups. Total breast pain scores were similar in both groups. The sensory component of breast pain questionnaire and visual analogue scale values significantly improved via exercise in only exercise group (p = 0.012 and p = 0.016). There was no significant difference between groups in serum levels of cytokines. SF-36 subscale scores for general health and social functioning significantly improved in the control group and scores for role physical, bodily pain, and social functioning improved in exercise group. CONCLUSIONS: Based on our preliminary findings, exercise treatment is beneficial for patients with mastalgia and it can be suggested by clinicians.

Adenoid Cystic Carcinoma of the Breast: A Clinical Case Report.

INTRODUCTION: Adenoid cystic carcinoma (ACC) is an uncommon tumor of the breast, accounting for approximately 0.1% to 1% of all breast cancers. It is characterized by rare lymph node involvement and distant metastasis, and associated with a favorable prognosis with excellent survival, despite its triple-negative status. In the current state of knowledge, results of breast-conserving treatment with postoperative radiotherapy seem to be equivalent to mastectomy alone, with respect to survival for ACC of the breast. Due to its rarity, there is no consensus on optimal treatment for patients with ACC. Otherwise, the role of chemotherapy and hormonal therapy remains controversial. Further clinical studies are required to compare treatment options for ACC. But, a long-term follow-up is very important and mandatory for affected patients, due to the late onset of local relapse and occurrence of distant metastasis. CASE REPORT: Here, we report the case of a patient who presented with a palpable breast mass in the left breast that turned out to be an ACC of the breast.

Urothelial carcinoma of the allograft kidney developed in a renal transplant patient.

Renal transplantation is the best option in the treatment of end-stage renal disease However these patients are under the risk of developing malignancies particularly due to effects of immune supression. These malignancies tend to be more agressive compared to the general population. Here, we present a case of urothelial carcinoma develoing in the ureter of allograft kidney.

The role of fine needle aspiration cytology and core biopsy in the diagnosis of palpable breast masses.

BACKGROUND: The modern approach to palpable breast masses is to get cytopathologic diagnosis before definitive surgery. We aimed to compare fine needle aspiration cytology (FNAC) with core biopsy in histopathologic diagnosis of palpable breast masses. MATERIALS AND METHODS: Data were collected on 123 women who have suspicious palpable breast masses from 2007 to 2010. RESULTS: Of the 123 patients, core biopsies were performed on 64 patients (Group 1) and FNAC on 59 patients (Group 2). Malignancy was confirmed in 25 out of 32 clinically suspicious patients in Group 1 (78.1%), and 20 out of 21 participants in Group 2 (95.2%). Among the clinically suspicious patients, 81.8% of 33 patients in Group 1, and 90.3% of 31 patients in Group 2 were identified malignancy. Sensitivity was 100% for core biopsy and 95% for FNAC. Specificity was 100% in both procedures. False negativity rate in FNAC were 5%. CONCLUSION: Sensitivity and specificity showed that in the case of true histopathologic classification, core biopsy is superior to FNAC. Nevertheless, FNAC's role as a fast, simple and cheap diagnosis cannot be ignored. It is an effective diagnostic tool in most patients, in comparison to the correct and specific typing of core biopsies in benign lesions which protect patients from the open biopsy.

Renal Angiomyolipoma With Caval Extension and Pulmonary Fat Embolism: A Case Report.

Renal angiomyolipoma (AML) is a rare benign tumor of the kidney. Occasionally, it may extend into the renal vein or the inferior vena cava (IVC), but so far of pulmonary embolism in patients with renal AML was rarely reported. Here, a case of symptomatic pulmonary embolism secondary to AML that was placed IVC filter before the operation and then treated with radical nephrectomy is reported.This case highlights the rare possibility of renal vein and IVC involvement with symptomatic pulmonary fat embolism in renal AML, which may potentially result in fatal complications if not appropriately and cautiously managed with surgical intervention.

The effects of ventilation with high density oxygen on the strength of gastrointestinal anastomosis.

PURPOSE: The aim of our study is to evaluate the effects of administration of perioperative supplemental oxygen on anastomoses. METHODS: Forty male Wistar albino rats were used in the study and randomized into 4 groups. Ischemia-reperfusion models were built in groups 3 and 4. Jejunojejunostomy was performed in all rats and assigned to an oxygen/nitrous oxide mixture with a fraction of inspired oxygen of 30% in groups 1 and 3 and 80% in groups 2 and 4. The measurements of perianastomotic tissue oxygen pressure, bursting pressure, level of hydroxyproline were evaluated and compared in all groups. RESULTS: The perianastomotic tissue oxygen pressures, bursting pressures and levels of hydroxyproline were identified as significantly high in groups 2 and 4, administered a fraction of inspired oxygen of 80%, compared to groups 1 and 3, administered a fraction of inspired oxygen of 30%. CONCLUSION: Perioperative supplemental oxygen contributes positively to the anastomotic healing.

Breast hamartoma: a clinicopathologic analysis of 27 cases and a literature review.

OBJECTIVES: Breast hamartoma is an uncommon breast tumor that accounts for approximately 4.8% of all benign breast masses. The pathogenesis is still poorly understood and breast hamartoma is not a well-known disorder, so its diagnosis is underestimated by clinicians and pathologists. This study was designed to present our experience with breast hamartoma, along with a literature review. METHOD: We reviewed the demographic data, pathologic analyses and imaging and results of patients diagnosed with breast hamartoma between December 2003 and September 2013. RESULTS: In total, 27 cases of breast hamartoma operated in the Ankara University Medicine Faculty's Department of General Surgery were included in the study. All patients were female and the mean age was 41.8±10.8 years. The mean tumor size was 3.9±2.7 cm. Breast ultrasound was performed on all patients before surgery. The most common additional lesion was epithelial hyperplasia (22.2%). Furthermore, lobular carcinoma in situ was identified in one case and invasive ductal carcinoma was observed in another case. Immunohistochemical staining revealed myoid hamartoma in one case (3.7%). CONCLUSION: Breast hamartomas are rare benign lesions that may be underdiagnosed because of the categorization of hamartomas as fibroadenomas by pathologists. Pathologic examinations can show variability from one case to another. Thus, the true incidence may be higher than the literature indicates.

Gastric metastasis of ectopic breast cancer mimicking axillary metastasis of primary gastric cancer.

Ectopic breast tissue has the ability to undergo all the pathological changes of the normal breast, including breast cancer. Gastrointestinal metastasis of breast cancer is rarely observed and it is very difficult to differentiate gastric metastases from primary gastric cancer. We present a case of 52-year-old female, who suffered from abdominal pain. Physical examination showed a palpable mass in the left anterior axilla and computerized tomography revealed gastric wall thickening with linitis plastica. When gastroscopic biopsy showed no signs of malignancy, excisional biopsy was performed in the left axilla. Histological examination revealed invasive lobular carcinoma of the breast, consistent with ectopic breast cancer. Further gastroscopic submucosal biopsies and immunohistochemical studies revealed gastric metastases of invasive lobular carcinoma. Axillary ectopic breast tissue carcinomas can mimic axillary lymphadenopathies. Additionally, gastric metastasis of breast cancer is an uncommon but possible condition. To the best of our knowledge, this is the first report of ectopic breast cancer with gastric metastasis.
