OBJECTIVE It is well established that Currarino syndrome (CS) may be associated with spinal dysraphism. Here, the authors report on 10 CS patients with dysraphic anomalies who had undergone a combined neurosurgical and general surgical approach to repair the dysraphic anomalies and resect the presacral mass in a single operation. They discuss the spectrum of spinal dysraphism that may coexist in CS in the context of its developmental etiology. METHODS Children with a confirmed CS diagnosis who had undergone the combined operative approach were identified from a departmental database...

BACKGROUND: Trauma to the perineum, levator ani complex, and anal sphincters is common during vaginal childbirth, but is often clinically underdiagnosed, and many women are unaware of the potential for long term damage. OBJECTIVES: In this study we use transperineal ultrasound to identify how many women will achieve a normal vaginal delivery without substantial damage to the levator ani or anal sphincter muscles, and to create a model to predict patient characteristics associated with successful atraumatic normal vaginal delivery...

BACKGROUND: In patients who undergo restorative proctocoletomy (RPC) a pouchogram is often used to assess the integrity of the ileal pouch-anal anastomosis (IPAA) before closing the covering ileostomy. There are no good data to support this practice. The aim of the study was to investigate whether contrast pouchography was clinically useful after RPC. METHODS: We conducted a retrospective study of patients who had undergone RPC with a covering ileostomy between September 2013 and September 2015...

Fistula-associated anal carcinoma in patients with Crohn's disease (CD) is a rare condition. More recently, this entity has been increasingly reported likely due to increased recognition, and the incidence may be greater than once appreciated. There remains a paucity of data regarding the incidence, diagnosis, treatment, and outcome of fistula-associated anal carcinoma. Area covered: This review evaluates the clinical features, pathology, treatment, and prognosis of fistula-associated anal carcinoma in patients with CD...

INTRODUCTION: The management of perirectal tumors often requires rectal wall resection, and sometimes a complete proctectomy is required. Access to posterior perirectal masses via a posterior, transcoccygeal approach (Kraske procedure) avoids dissection of the intraperitoneal rectum. PATIENT: The patient was a 63-year-old male who presented to his primary care physician with debilitating perirectal pain of several months' duration. He did not respond to therapy with pain medications and topical agents, and underwent a lateral internal sphincterotomy for what was thought to be an anal fissure, without relief prior to referral...

PURPOSE: Disorders related to pelvic floor include urinary incontinence (UI), anal incontinence, pelvic organ prolapse, sexual dysfunction and pelvic pain. Because pelvic floor dysfunctions (PFD) can be diagnosed clinically, imaging techniques serve as auxiliary tools for establishing an accurate diagnosis. The objective is to evaluate the PFD in primiparous women after vaginal delivery and the association between clinical examination and three-dimensional ultrasonography (3DUS). METHODS: A cross-sectional study was conducted in a in tertiary maternity...

Esophageal lung is a rare communicating bronchopulmonary foregut malformation in which the main bronchus arising from the trachea is absent. The affected lung is usually hypoplastic and aerated via an anomalous airway originating from the esophagus. Other anomalies such as esophageal atresia with tracheoesophageal fistula or VACTERL (vertebral defects, anal atresia, cardiac defects, tracheoesophageal fistula, renal anomalies, and limb abnormalities) association can co-exist. The initial radiographic findings may be normal, but subsequent imaging usually shows progressive and recurrent lung collapse, probably because of recurrent aspiration through the anomalous airway and poor compliance of the affected lung during breathing...

Atopic transverse myelitis is a rare disorder that is defined as a localized myelitis of an unknown cause in patients with either high immunoglobulin E (IgE) level or mite-specific IgE or coexistent atopic disease. It is a cause of intramedullary cord lesions, but its diagnosis does not need tissue confirmation. We report a case of a patient who presented with bladder and anal incontinence, paresthesia, and lower limb weakness. Neither IgE level nor mite-specific IgE level could be determined due to lack of fund; however, magnetic resonance imaging (MRI) of the thoracolumbar region showed hypotense-isotense lesion within the spinal cord at T4 vertebral level, suggestive of transverse myelitis...

Radiotherapy is the standard of care in the multimodality treatment of a variety of gastrointestinal (GI) tumours, such as oesophageal cancer, gastric cancer, rectal cancer and anal cancer. Additionally, radiotherapy has served as an alternative for surgery in patients with liver cancer, cancer of the biliary tract and pancreatic cancer. Positron-emission tomography (PET), generally in combination with computed tomography (CT), has an established role in the diagnosis, response assessment and (re-)staging of several GI tumours...

BACKGROUND: Pelvic intraoperative neuromonitoring during nerve-sparing robot-assisted total mesorectal excision (RTME) is feasible. However, visual separation of the neuromonitoring process from the surgeon console interrupts the workflow and limits the usefulness of available information as the procedure progresses. Since the robotic surgical system provides multi-image views in the surgeon console, the aim of this study was to integrate cystomanometry and internal anal sphincter electromyography signals to aid the robotic surgeon in his/her nerve-sparing technique...

BACKGROUND: One of the minimally invasive methods used in the surgical treatment of large-based polypoid lesions located in the rectum is transanal minimally invasive surgery (TAMIS). This method, which relieves patients from the severe morbidities of invasive surgical procedures, is performed in both malign (T1-T2) and benign lesions. Difficulty of suturation after TAMIS emerges as the most important factor to prolong the procedure. We aimed to analyse the efficacy of TAMIS procedure with partial thickness resection without suturation...

Ileal pouch-anal anastomosis, or J pouch, surgery has become the procedure of choice for treatment of medically refractory ulcerative colitis and familial adenomatous polyposis. Overall, this operation is associated with a low rate of postoperative morbidity and good long-term function. However, when complications develop, there is a heavy reliance on imaging to facilitate an accurate diagnosis. Reported postoperative complication rates range from 5% to 35%. Complications generally can be categorized as structural, inflammatory, or neoplastic conditions...

Aggressiveness in honeybees seems to be regulated by multiple genes, under the influence of different factors, such as polyethism of workers, environmental factors, and response to alarm pheromones, creating a series of behavioral responses. It is suspected that neuropeptides seem to be involved with the regulation of the aggressive behavior. The role of allatostatin and tachykinin-related neuropeptides in honeybee brain during the aggressive behavior is unknown, and thus worker honeybees were stimulated to attack and to sting leather targets hung in front of the colonies...
