Body donation for research and teaching purposes: the contribution of blood donation units in the progress of anatomical science. Folia Morphol (Warsz). 2018.
AbstractCadaver's dissection has a fundamental role in teaching and understanding the anatomy. Postmortem body donation (PMBD) is an important source of cadavers and provides an opportunity to carry out research or educational activities in medicine and surgery. The objective of the current study is to determine the perspectives and attitudes toward PMBD among blood donors (BLD) and elderly people. These data are fundamental to highlight the PMBD extent and individual factors that might influence PMBD. Concerning the perception of body donation (BD) among BLD and elderly, the most common reason for BD was the contribution in research, in both study groups, while the commonest reason for hesitating BD was the lack of information following by personal reasons, concerning BLD and the elderly. The BLD were more likely to be interesting in BD for contribution in research and personal reasons. Additionally, BLD compare to the elderly were less likely to hesitate BD for religious and personal reasons and more likely to hesitate BD for not being informed. BLD who interested in BD for contribution in research were significantly older. Elderly that hesitated BD for personal reasons was significantly older. In BLD group, those that responded that blood and body donation are the same were significantly younger, while in the elderly were significantly older. The proportion of BLD that declared that blood and body donation is the same was significantly higher in more educated people. A need for well-organized and informative BD programs is evident. Orientating the public towards this practice is of high moral and medical value, since with this important promotion the altruistic act of BD will expand globally.

Complete unilateral ureteral duplication encountered during intersphincteric resection for low rectal cancer. J Surg Case Rep. 2018;2018(10):rjy266.
AbstractComplete duplication of ureters is a very rare clinical entity that may either be asymptomatic or present with a variety of clinical findings. In the presented case a 51-year-old Caucasian female underwent an intersphincteric resection for low rectal cancer. Intraoperatively, during the standard bilateral recognition and mobilization of the ureters, complete unilateral duplication of the left ureter was incidentally detected, deriving from a single renal parenchyma. Such a congenital abnormality though constitutes a major risk-factor of accidental ureteral injury during operations including pelvis. Conclusively, meticulous exposure of both ureters combined with surgeons' unceasing awareness constitute the cornerstone of a safe operation.

Anatomic variation of the relation between the inferior mesenteric artery and the bifurcation point of abdominal aorta during lower anterior resection: A rare case report. Int J Surg Case Rep. 2018;51:385-387.
AbstractINTRODUCTION: Identification and ligation of the inferior mesenteric artery (IMA) is a crucial surgical step when performing lower anterior resection (LAR) for rectal cancer. Anatomic variations of the relation between the IMA and the bifurcation point of abdominal aorta (AA) encumber surgical maneuvers and are of great clinical importance.
PRESENTATION OF CASE: An unusual anatomic variation of the relation between IMA and the bifurcation point of AA was unexpectedly detected during LAR to a 69-year-old Caucasian female patient. The operation was uneventful. A meticulous review of the recent literature was conducted as well.
DISCUSSION: Variations of the mesenteric vascular supply are mainly identified incidentally, during the operation. In particular, variations of IMA are extremely uncommon in the literature. However, such kind of congenital variations, are not as rare as considered and their presence encumbers surgical maneuvers and increases the potentiality of intraoperative injury and hemorrhage.
CONCLUSION: Surgeons' deep knowledge and unceasing awareness concerning probable anatomic variations of the relation between the IMA and AA, combined with detailed exposure of the operative field and of the relationship between these adjacent arteries constitute the cornerstone of a safe operation.

AbstractRight or subtotal colectomy either open or laparoscopic may be a challenging operation owing to technical difficulties. One of these, is to identify a safe and adequate dissection plane, ligating and dissecting lymph nodes around middle colic vessels. The purpose of this study was to depict a rare anatomic variation of middle colic vein (MCV) draining to splenic vein. We report the case of a 55-year-old male patient, who was subjected to a right hemicolectomy for an adenocarcinoma in the ascending colon. During dissecting the transverse mesocolon from the greater omentum, for complete mesocolic excision (CME), we encountered that the MCV drained in the splenic vein. With respect of this rare anatomic variability, CME was completed without hemorrhage. Our aim is to depict that deep knowledge of MCV anatomy and its variations is of paramount importance to achieve CME and to avoid dangerous or massive bleeding.

Anomalous course of the sigmoid colon and the mesosigmoid encountered during colectomy. A case report of a redundant loop of sigmoid colon. Int J Surg Case Rep. 2018;46:20-23.
AbstractIntroduction Sigmoid colon constitutes a part of the large intestine that presents several congenital anatomic variations. In particular, the presence of a redundant loop of sigmoid colon is of tremendous importance for surgeons, obstetricians and radiologists, since it is closely related to multiple pathological conditions and functional implications of the neighboring anatomical structures.
PRESENTATION OF CASE: An unusual anatomic variation in position and length of the sigmoid colon and its mesocolon was unexpectedly detected during right hemicolectomy to a 67-year-old Caucasian male patient due to colon cancer. The operation was uneventful. A meticulous review of the literature was conducted as well.
DISCUSSION: A redundant loop of sigmoid colon may go unnoticed or it might lead to urinary, digestive and vascular complications. Its presence is associated with acute and chronic pathological conditions, sigmoid volvulus and serious confusions in radiological diagnosis and instrumentation.
CONCLUSION: Surgeons' thorough knowledge concerning this rare anatomic variation is fundamental and crucial in order to establish a correct diagnosis and assert the appropriate management when performing operations including pelvis and abdomen.

Laparoscopic abdominoperineal resection for the treatment of a mucinous adenocarcinoma associated with an anal fistula. J Surg Case Rep. 2018;2018(3):rjy036.
AbstractMucinous adenocarcinoma associated with an anal fistula is a rare oncologic entity which may pose diagnostic and therapeutic challenges for Surgeons and Medical Oncologists. Few reported cases without definite therapeutic guidelines exist. It represents 2-3% of all gastrointestinal malignancies and arises from chronic anal fistulas, ischiorectal or perianal abscesses. We report a case of perianal mucinous adenocarcinoma in a 65-year-old male initially surgically treated multiple times for a recurrent fistula in ano of 5 years duration. He presented with an ischiorectal and a perianal fistula. Incisional biopsy from fistulotomy revealed mucinous adenocarcinoma. Contrast enhanced computed tomography scan and magnetic resonance imaging showed a localized perianal growth of a tumor which was further evaluated with colonoscopy. With no evidence of metastasis, we performed a laparoscopic abdominoperineal resection (APR). Two years follow-up after APR and without adjuvant chemotherapy there is not any evidence of recurrence or distant metastasis.

Improving diagnosis, prognosis and prediction by using biomarkers in CRC patients (Review). Oncol Rep. 2018;39(6):2455-2472.
AbstractColorectal cancer (CRC) is among the most common cancers. In fact, it is placed in the third place among the most diagnosed cancer in men, after lung and prostate cancer, and in the second one for the most diagnosed cancer in women, following breast cancer. Moreover, its high mortality rates classifies it among the leading causes of cancer‑related death worldwide. Thus, in order to help clinicians to optimize their practice, it is crucial to introduce more effective tools that will improve not only early diagnosis, but also prediction of the most likely progression of the disease and response to chemotherapy. In that way, they will be able to decrease both morbidity and mortality of their patients. In accordance with that, colon cancer research has described numerous biomarkers for diagnostic, prognostic and predictive purposes that either alone or as part of a panel would help improve patient's clinical management. This review aims to describe the most accepted biomarkers among those proposed for use in CRC divided based on the clinical specimen that is examined (tissue, faeces or blood) along with their restrictions. Lastly, new insight in CRC monitoring will be discussed presenting promising emerging biomarkers (telomerase activity, telomere length and micronuclei frequency).

Abnormal distance of the extralaryngeal bifurcation point of the recurrent laryngeal nerve from the cricothyroid joint. J Surg Case Rep. 2018;2018(1):rjx257.
AbstractThe extralaryngeal bifurcation point of the recurrent laryngeal nerve (RLN) is typically located in a mean distance of 0-2 cm from the cricothyroid joint (CTJ). In the presented case though, the left RLN was unexpectedly identified bifurcating in a mean distance of 7 cm from the left CTJ in a young woman with multinodular goiter during total thyroidectomy. The RLN was carefully exposed throughout its course for the avoidance of iatrogenic injury of the nerval structure. The operation was uneventful. The present manuscript aims to highlight a scarce anatomic variation and its implications for thyroidectomy. Rare anatomic variations of the RLN such as the presented one encumber thyroid surgery and represent a severe risk factor of RLN injury. Meticulous operative technique combined with surgeons' perpetual awareness concerning this peculiar anatomical aberration leads to an injury-free thyroid surgery.
