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...

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. Contudo, no campo da cirurgia colorretal, a aceitação da videolaparoscopia foi mais lenta. Exemplificando, um estudo norte-american...

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...

The role of Phosphatidylinositol 3 kinase (PI3K) and Cycloxygenase-2 (COX2) in carcinogenesis of colorectal polyps
ConclusionsThe greater expression of the proliferation marker and Phosphatidylinositol 3 kinase in the right colon may be related to right-sided colorectal carcinogenesis. The proliferation marker, Cycloxygenase-2 and Phosphatidylinositol 3 kinase results can be associated with progression of polyps to colorectal cancer. The higher Phosphatase and tensin homolog expression suggests its attempt to control the cell cycle.ResumoObjetivosDeterminar a expressão imuno-histoquímica de Fosfatase homóloga a tensina (PTEN), Fosfatidilinositol-3-cinase (PI3K), Ciclooxigenase-2 (COX2) e um marcador de proliferação (Ki67) em póli...

Association of sociodemographic and clinical factors with self-image, self-esteem and locus of health control in patients with an intestinal stoma
ConclusionsOstomized patients presented alterations in the following variables: unemployed, retired, aged up to 50 years and unmarried. There were also alterations in individuals whose cause of the stoma was neoplasia, a temporary stoma, stoma time <4 years, and ostomized non-participants of an association or support group, and who also did not practice physical activities. We conclude from these findings that ostomized individuals who participated in the study and who were included in these variables showed negative feelings about their body and believed that only they could control their health and that the people in...
