Compared to Europe and America, the specialization of colorectal and anal surgery in China started a bit late, and so far there has been no standardized residency program and expert-access system. This review introduces different training systems of colorectal and anal surgery residency in the United States, Europe, and Japan, aiming to provide references for the establishment of residency program in China, which is imperative. Firstly, national uniform identification standards for standardization training bases of colorectal and anal surgeons are required...

Multiple primary malignancy is defined as two or more malignancies detected in an individual person. In particular, synchronous quintuple primary malignancy is extremely rare. A 52-year-old male with anal pain and intermittent blood-tinged stool was diagnosed with malignancies in the stomach, jejunum, ascending colon, transverse colon and rectum. He underwent a subtotal gastrectomy, segmental resection of the jejunum and total protocolectomy with end ileostomy. The postoperative pathologic findings were moderate differentiated gastric adenocarcinoma (pT1bN0M0, pStageIA), combined adenocarcinoma and neuroendocrine carcinoma of the jejunum (pT3N0M0, pStageIIA), three mucinous adenocarcinoma of the ascending colon (pT3N0M0, pStageIIA), transverse colon (pT1N0M0, pStageI) and rectum (pT3N1aM0, pStageIIIB)...

BACKGROUND: Rectal prolapse is defined as the protrusion of the rectal wall through the anal canal; with a prevalence of less than 0.5%. The most frequent symptoms include pain, incomplete defecation sensation with blood and mucus, fecal incontinence and/or constipation. The surgical approach can be perineal or abdominal with the tendency for minimal invasion. Robot-assisted procedures are a novel option that offer technique advantages over open or laparoscopic approaches. CASE REPORT: 67 year-old female, who presented with rectal prolapse, posterior to an episode of constipation, that required manual reduction, associated with transanal hemorrhage during defecation and occasional fecal incontinence...

AIM: To determine the anatomical organization and somatic axonal components of the lumbosacral nerves in female rabbits. METHODS: Chinchilla adult anesthetized female rabbits were used. Anatomical, electrophysiological, and histological studies were performed. RESULTS: L7, S1, and some fibers from S2 and S3 form the lumbosacral trunk, which gives origin to the sciatic nerve and innervation to the gluteal region. From S2 to S3 originates the pudendal nerve, whose branches innervates the striated anal and urethra sphincters, as well as the bulbospongiosus, ischiocavernosus, and constrictor vulvae muscles...

OBJECTIVES: Ileorectal anastomosis (IRA) affects bowel function, sexual function and reproduction less negatively than ileal pouch anal anastomosis (IPAA), the standard reconstruction after colectomy for ulcerative colitis (UC). In younger UC patients, IRA may have a role postponing pelvic surgery and IPAA. The aim of the present study was to investigate the survival of IPAA secondary to IRA compared to IPAA as primary reconstruction, as this has not previously been studied in UC. PATIENTS AND METHODS: All patients with UC diagnosis between 1960 and 2010 in Sweden were identified from the National Patient Registry...

BACKGROUND: Although HIV and syphilis co-infection has been frequently observed in men who have sex with men (MSM), only few studies have focused on it. Different subgroups of MSM might exhibit heterogeneous HIV and syphilis risk profiles, indicating that interventions for HIV and HIV-related co-infections may vary with different subgroups of MSM. However, no previous study has investigated HIV and syphilis co-infection among non-commercial MSM (ncMSM) attending a sexually transmitted disease (STD) clinic...

BACKGROUND AND AIM: Chemoradiotherapy (CRT) is the gold standard treatment for anal cancer, which permits the maintenance of the anal function. However, about 30-40% of patients develop local disease progression, for which surgery represents a good salvage therapy. The aim of this study is to evaluate survival and morbidity rate in patients who undergo salvage surgery in our single institution, with an overview of the literature. METHODS: A retrospective study was carried out on patients who underwent surgical treatment of anal canal cancer after failure of CRT...

BACKGROUND AND AIMS: Laparoscopic resection is a well-established approach for colorectal cancer surgery. In patients with rectal cancer treated by neoadjuvant chemoradiotherapy, it may be difficult to identify a clear safety margin for endostapling and subsequent anastomosis. We designed an innovative technical approach to assist colorectal anastomosis in these patients. TECHNIQUE: A four-trocar laparoscopic approach is used. After exploration of the abdominal cavity, the left colic flexure is completely mobilized...

Hirschsprung disease is a congenital disease characterized by intestinal aganglionosis of various extents. Most patients are younger than 1 year of age. Though, a minority of cases can be older or even adult. Older the patient the more difficult and prolonged is the endorectal dissection required for the pull-through procedure. Longer surgery leads to longer anal dilatation and trauma with subsequent higher likelihood of continence impairment. The article aims at describing the first case series of robot-assisted Soave procedure, which was adopted as an alternative minimally invasive approach to older patients with Hirschsprung disease...

Routine histopathologic examination of hemorrhoidectomy specimens is controversial having been described as not useful and expensive with few of these common cases demonstrating incidental lesions. However, unexpected premalignant and malignant lesions have been detected on excised hemorrhoids. The high-risk human papillomavirus (HR-HPV) types associated with these incidentally identified high-grade lesions are presently unknown. We aimed to identify cases of incidental high-grade anal intraepithelial neoplasia (HG-AIN) and anal squamous cell carcinoma incidentally discovered on hemorrhoidectomy specimens, genotype HR-HPVs from these lesions, and assess p53 and p16 expression by immunohistochemistry to identify risk factors for their development...

Fish color patterns are among the most diverse phenotypic traits found in the animal kingdom. Understanding the molecular and cellular mechanisms that control in chromatophore distribution and pigmentation underlying this diversity is a major goal in developmental and evolutionary biology, which has predominantly been pursued in the zebrafish model system. Here, we apply results from zebrafish work to study a naturally occurring color pattern phenotype in the fins of an African cichlid species from Lake Tanganyika...

BACKGROUND: Although the incidence of HPV-attributable cancers in males is rapidly increasing, HPV vaccine uptake in males remains poor. While quadrivalent human papillomavirus vaccine (4vHPV) series initiation in males increased following the Advisory Committee Immunization Practices (ACIP) male routine use recommendation, its impact on 4vHPV series completion in males at ACIP-recommended intervals has not been evaluated in large male cohorts. We examined trends and correlates of 4vHPV completion since licensure in males in a large cohort of insured boys before and after the ACIP routine use recommendation...
