We treated a 64-year-old man for rectal cancer with direct invasion to the seminal vesicles and no distant metastases by complete resection with laparoscopy and transanal minimally invasive surgery (TAMIS). We inserted the TAMIS device into the anal canal to above the anorectal ring and dissected to prostate level. High ligation of the inferior mesenteric artery and vein was performed by standard medial laparoscopy. The sigmoid and descending colon were mobilized, and in the postrectal space, we dissected to the space made by TAMIS...

Hans Peter Dietz
Since its introduction in the early 1990s, endoanal sonography has become the mainstay of morphologic assessment of the anal canal and sphincter, especially for obstetric anal sphincter trauma. Lack of availability of suitable systems and the invasive nature of the method have limited uptake and clinical utility. More recently, exoanal or transperineal/translabial tomographic imaging has been developed as a noninvasive alternative. This pictorial overview aims to introduce the reader to this new diagnostic modality and to demonstrate common findings in asymptomatic and symptomatic women...

Inherently, brachytherapy is the most conformal radiotherapeutic technique. As an aid to brachytherapy, ultrasonography (USG) serves as a portable, inexpensive, and simple to use method allowing for accurate, reproducible, and adaptive treatments. Some newer brachytherapy planning systems have incorporated USG as the sole imaging modality. Ultrasonography has been successfully used to place applicator and dose planning for prostate, cervix, and anal canal cancers. It can guide placement of brachytherapy catheters for all other sites like breast, skin, and head and neck cancers...

PURPOSE: Although the standard treatment for patients with locally advanced rectal cancer managed by preoperative chemoradiotherapy (CRT) is a radical resection, local excisions are used in highly-selective cases. Recently, transanal minimally-invasive surgery (TAMIS) has emerged as a feasible technique for local excision of midrectal lesions. We assess the feasibility of using TAMIS to treat patients with locally advanced rectal cancer who showed good response to CRT. METHODS: From October 2010 to June 2013, 35 consecutive patients with rectal cancer managed by using preoperative CRT underwent TAMIS...

BACKGROUND: Anogenital warts (AGW) are one of the most prevalent sexually transmitted disease worldwide. Approximately 90% of AGWs are related to infection by HPV 6 and 11. However, AGW have been associated with infection by multiple genotypes, including HR-HPV, which may be associated with a long-term increased risk of anogenital cancer. OBJECTIVE: This observational prospective epidemiological study aims to estimate the type-specific HPV distribution on incident AGWs in both genders, and additionally to assess the frequency of anal and oral HPV infection in patients with AGWs...

We describe a highly unusual case of solitary rectal ulcer syndrome (SRUS) that presented as a large polyp protruding from the anal canal. A 67-year-old man presented with rectal bleeding and mucus discharge. At examination under anaesthesia, a large pedunculated polypoidal lesion was found, measuring 25 × 20 mm, arising posterolaterally from the anorectal junction and protruding externally 50 mm in size. SRUS can be a misnomer as the condition can present in a number of different ways and only a minority of patients has a solitary ulcer...

Infection with certain types of human papillomavirus (HPV) has been associated with the development of cervical and anal cancer. Worldwide, the incidence of anal cancer has increased markedly. The present study aimed to evaluate the prevalence of HPV infection of the uterine cervix and anal canal in human immunodeficiency virus (HIV)- and non-HIV-infected risk populations. Cervical and anal HPV swabs and cytology samples were collected from 287 patients at the University Hospital of Munich, Germany between 2011 and 2013...

Wnt-β catenin is an important signaling pathway in the genesis of fibrosis in many organ systems. Our goal was to examine the role of Wnt pathway in the external anal sphincter (EAS) injury-related fibrosis and muscle dysfunction. New Zealand White female rabbits were subjected to surgical EAS myotomy and administered local injections of either a Wnt antagonist (sFRP-2; daily for 7 days) or saline. Anal canal pressure and EAS length-tension (L-T) were measured for 15 weeks after which the animals were sacrificed...

BACKGROUND: Anal fissure is the most common anal disease in children. In the past few decades, the understanding of its pathophysiology has led to a progressive reduction in invasive procedures in favor of conservative treatment based on stool softeners and the relaxation of the anal sphincter. This randomized controlled study assessed the safety and efficacy of nitroglycerine (NTG) ointment in the treatment of pediatric anal fissure, which had not yet been proved. PATIENTS AND METHODS: An unequal randomized controlled study included 105 pediatric patients with anal fissure who had presented to the private and outpatient clinics of the Central Teaching Hospital of Pediatrics during the period from February 2015 to May 2016...

BACKGROUND & AIMS: Despite evidence that most non-malignant colorectal polyps can be managed endoscopically, a substantial proportion of patients with a non-malignant colorectal polyp are still sent to surgery. Risks associated with this surgery are not well characterized. We aimed to describe 30-day post-operative morbidity and mortality and to explore risk factors for adverse events in patients undergoing surgical resection for non-malignant colorectal polyps. METHODS: We analyzed data collected prospectively as part of the National Surgical Quality Improvement Program...

Ileoanal pouch anastomosis is the procedure of choice for patients with drug refractory ulcerative colitis, indeterminate colitis and familial adenomatous polyposis (FAP). In selected patient groups this procedure is a treatment option for patients with Crohn's disease, hereditary nonpolyposis colorectal cancer (HNPCC), synchronous colorectal cancer and for severe colorectal constipation refractory to conservative drug treatment. The pouch procedure provides the opportunity to avoid a permanent ileostomy. The majority of surgeons prefer the ileal J‑pouch as the construction is the easiest to perform and complications and dysfunction rates are low...

Patients with inflammatory bowel disease [IBD] may develop, similarly to individuals from general population, rare cases of human papilloma virus [HPV]-related anal canal squamous cell carcinoma [SCC] and intra-epithelial precursor lesions, as well as very rare cases of anal canal adenocarcinoma. Patients with chronic perianal Crohn's disease [CD] are at substantial risk of developing SCC or adenocarcinoma from the fistula-lining epithelium, as well as SCC or adenocarcinoma arising from chronic anorectal ulcerations or strictures...

PURPOSE: A 23-year-old lady had an incompletely excised perianal sarcoma. Brachytherapy as the sole treatment, rather than further surgery or external beam radiotherapy, was considered to be the best option with the least morbidity. METHODS AND MATERIALS: Although brachytherapy techniques with iridium-192 for anal and rectal carcinoma are well described using a perianal template, the size of the template was not suitable for a two-plane implant that needed to be in situ for about 4 days...

Anal cytology has been suggested as a screening test for the anal cancer precursor high-grade squamous intraepithelial lesion (HSIL). We aimed to assess the prevalence and predictors of initial unsatisfactory anal cytology tests ('unsats'). The Study of the Prevention of Anal Cancer is a natural history study of anal human papillomavirus (HPV) and precancerous lesions among gay and bisexual men (GBM) of at least 35 years in Sydney, Australia. At each study visit, an anal swab is collected for cytological testing...

BACKGROUND: Sacrococcygeal pilonidal disease is a chronic, well-recognized entity, characterized by the recurrent formation of an abscess or draining sinus over the sacrococcygeal area. It is one of the most common surgical problems. Rarely, chronic inflammation and recurrent disease leads to malignant transformation, most commonly to squamous cell carcinoma (SCC). CASE PRESENTATION: We describe an extremely unusual case of SCC developing in a 60-year-old patient with a chronic pilonidal sinus complicated by an anal fistula...
