Colonic fibromatosis ‒ a case report and review of the literature
We report a case of a 60-year-old patient with a large right colonic mass who underwent right hemicolectomy. Histology proved morphological and immuno-histochemical features indicating fibromatosis. This desmoid tumour appeared growing from the colonic wall rather than the mesocolon, confirming a true colonic wall fibromatosis, a deep isolated form of intra-abdominal fibromatosis. Surgical resection is the treatment of choice in isolated well confirmed lesions. Multidisciplinary team approach is crucial for treatment and prognosis.ResumoOs tumores desmoides intra-abdominais são muito raros e geralmente ocorrem em paciente...

Recurrence pattern of rectal cancer after surgical treatment. Analysis of 122 patients in a tertiary care center
This study aims to establish a recurrence pattern for rectal adenocarcinoma submitted to surgical treatment between March 2003 and July 2016. After exclusion criteria were applied, one hundred twenty two patients were analyzed. Global recurrence was found in 22% of them, while 13.1% have had local recurrence. Disease-free survival was 23.9 months, in average, and medium follow-up was 34.13 months, varying from 6 to 115 months. Recurrence, in literature, is usually between 3 and 35% in 5 years, and shows a 5-years survival rate of only 5%. Around 50% of cases, recurrence is local, confined to pelvis. This data followed lite...

New methodologies for old problems: tridimensional gastrointestinal organoids and guts-on-a-chip
ConclusionsDespite the still discrete number of publications, in quantitative terms, there are qualitative promising and consistent results addressing physiopathological aspects and new therapeutic perspectives of tridimensional in vitro cultures in the gastroenterology field. It is expected, thus, that such new methodological approaches, including organoids and guts-on-a-chip, may contribute decisively to the advance in knowledge on basic aspects, as well as on the translation to new therapeutic approaches in gastrointestinal diseases.ResumoObjetivosA presente revisão visou apresentar uma abordagem crítica dos avanços ...

Anatomical, surgical and clinical considerations related with operative procedures performed in combined abdominal and perineal approaches for the treatment of lower rectal cancer
ConclusionThe APPEAR (Anterior Perineal Plane for Ultra Low Anterior Resection) procedure is the most known surgical procedure in which the combined abdominal and anterior perineal approach is used. Combined abdominal and perineal (anterior or posterior) approaches can be described as surgical procedures in which the sphincter-saving extrasphincteric dissection and proximal segmental sphincteric excision techniques are performed.ResumoExperiência e objetivoAs abordagens abdominais e perineais (anterior ou posterior) combinadas, utilizadas na cirurgia para o câncer retal baixo, têm se baseado em características anatômi...

Three-dimensional virtual reconstruction as a tool for preoperative planning in the management of complex anorectal fistulas
The objective of this work is to describe the development and initial experience of the construction of a virtual three-dimensional model of the pelvic anatomy of a patient, allowing the exact identification of the relationships between the fistulous tracts of complex anorectal fistulas and the other pelvic structures. An MRI was performed on this patient, and the images were exported to the Vitrea fX Workstation® software. A radiologist did the analysis and segmentation of the images that were then sent to a three-dimensional image processor (Meshlab v. 1.3.3 – ISTI – CNR Research Center, Pisa University, Italy). The...

A novel four quadrant laser sphincterotomy for idiopathic severe anal stenosis
Publication date: January–March 2018Source: Journal of Coloproctology, Volume 38, Issue 1Author(s): Ashwin Porwal, Paresh Gandhi, Deepak KulkarniAbstractAnal stricture or stenosis, though uncommon, is disabling condition. It affects the quality of life due to pain, bleeding and difficulty in defecation, incontinence or increased frequency. It occurs when the normally pliable anoderm is replaced with fibrotic connective tissue, leading to an abnormally tight and inelastic anal canal. Mostly it occurs secondary to trauma, iatrogeny, inflammatory diseases, radiation or neoplasia. The treatment of anal stricture is generally...

Perianal hidradenoma papilliferum
Publication date: January–March 2018Source: Journal of Coloproctology, Volume 38, Issue 1Author(s): Eduardo Rosetti Filho, Fernanda Bellotti Formiga, Sabrina Miotto, Galdino José Sitonio FormigaAbstractHidradenoma papilliferum is a benign cystic tumor originated in apocrine sweat glands of the anogenital region. It is common in vulvar topography and rare in the perianal region. A well-documented case of a patient with slow-growing perianal nodulation without pain or other symptoms is reported. The histological study shows a hidradenoma papilliferum. The article reviews the topic and discusses the importance of the diffe...

Acute appendicitis mimicking acute scrotum: a rare complication of a common abdominal inflammatory disease
ConclusionAcute appendicitis can mimic acute scrotum and surgeons must have a high index of suspicion of this complication for diagnosing. This unusual clinical presentation may be challenging and can delay the diagnosis leading to perforated peritonitis.ResumoIntroduçãoA apendicite aguda é a doença cirúrgica mais comum do abdome na prática clínica, afetando principalmente adultos jovens. Tem uma grande variedade de apresentações clínicas, devido à variação anatômica do apêndice cecal. Sua apresentação como escroto agudo e abscesso escrotal é bastante rara e atípica, ocorrendo principalmente em pacientes...

Overview of colorectal resections in a reference center in Curitiba – Brazil: Experience with open and laparoscopic approach
ConclusionsVideolaparoscopic approach is a safe and effective option in the treatment of colorectal diseases. Surgery duration and anastomotic fistula rates are similar to the open resections. Hospital stay and ICU stay durations, however, were shorter in patients submitted to laparoscopic colectomies.ResumoIntroduçãoAbordagens minimamente invasivas passaram a ser a opção preferencial para tratamento de doenças cirúrgicas do trato gastrointestinal, graças às suas numerosas vantagens.
