[Transmural rectal endometriosis as a cause of chronic constipation. A case report and literature review].

The incidence of intestinal endometriosis is reported between 5.3 and 12% of cases and of these, between 70 and 93% are located in the rectum and sigmoid. We report the case of a 32-year-old with constipation and bloating and cramping pain during the last 2 years.

Spontaneous rupture of the spleen secondary to amyloidosis.

Background: Rupture of the spleen has been classically associated with trauma. It sometimes is a spontaneous event or may be secondary to a pathological condition of the spleen or even in a healthy spleen. Systemic amyloidosis is characterized by the extracellular deposition of amyloid proteins in one or more organs.

[Double stapler technique in colorectal surgery].

Background: Colorectal surgery has evolved significantly during the last 35 years. The circular stapler and the double stapler techniques have favored the development of very low rectal anastomoses with reduction in anastomotic leakage. The objective of this study is to evaluate the functional results and complication rate of this surgical technique in the Department of Colorectal Surgery at the Hospital de Especialidades, Centro Medico Nacional Siglo XXI and at the Hospital Angeles del Pedregal, both located in Mexico City.

[Quality of life after restorative proctocolectomy with ileo-anal J pouch in patients with ulcerative colitis].

Background: Restorative proctocolectomy with ileal pouch-anal anastomosis has become the most common treatment in patients with ulcerative colitis. This procedure removes the entire colon, conserving the sphincteric complex and, therefore, preserving continence. The most important goal of this surgery is to improve quality of life.

[Pneumatosis coli].

Objective: To report a pneumatosis coli case.

Case Report: A 56 year old man was submitted to a routine medical check up. During rectosigmoidoscopy examination many submucous lesions of cystic aspect were found, which were demonstrated by different imaging methods and endoscopy.

[Hemorroidal disease in a specialty medical center].

Background Data: Haemorrhoids and the symptoms they produce have been recorded throughout history. This disease affects 4-10% of the population. The treatment is based on the degree of haemorrhoidal prolapse and the severity of symptoms.

[Hereditary mixed polyposis syndrome. First report in Mexico].

Objective: Report for first time in Mexico a case of hereditary mixed polyposis and review the literature.

Background: The hereditary mixed polyposis syndrome (HMPS) is an uncommon condition, distinguished by presence of a different histological pattern of polyps in digestive tract, clinically manifested by diarrhea, anemia and weight loss.

Case Report: Male patient, 38 years old, with familiar antecedent (dead sister) with polyps and gastric cancer.

[Anal incontinence caused by an obstetric trauma. Experience with the technique of overlapping sphincteroplasty].

Introduction: Anal incontinence (IA) could be of idiopathic, congenital, neurological origin, or secondary to trauma. Obstetric trauma is the most common cause of the traumatic anal incontinence.

Objective: To analyze results of a group of patients with anal incontinence secondary to obstetric trauma, with overlapping sphincteroplasty.

[Surgical treatment of complete rectal prolapse. Experience at a colon and rectal surgery service].

Background: Rectal prolapse is as ancient humanity. Treatment must be surgical in adult patients. There is no gold standard procedure to date; thus, this has given rise to controversy.

[Perianal leukemic infiltration. Case report].

Background: Leukemic infiltration of perianal skin (leukemia cutis) is quite uncommon, and may consist of no diffuse infiltration, erythema, ulceration, fistula, and abscess. Diagnosis may be established by biopsy and adequate hematologic studies. Treatment must be conservative in patients with poorly controlled disease (sitz baths, antibiotics, radiotherapy), and surgical in patients with risk of fulminant sepsis and death.

[Surgical treatment of unspecific chronic ulcerative colitis. A 5-year experience].

Background: Treatment of ulcerative colitis depends on clinical stage of disease and have precise surgical indications. The aim of this work was to review surgical indications and present data related to our experience.

Material And Methods: Retrospective, descriptive, and transversal study.

[Ischemic colitis in patients submitted to aortic replacement surgery. Risk factors].

Unlabelled: Ischemic colitis (IC) is an important clinical problem, and may present after aortic surgical procedures. The aim of this work was to establish risk factors for IC presentation in aortic surgical replacement patients.

Material And Methods: A retrospective study of patients with aortic surgical replacement in a 3-year period was carried out.

Helicoidal suture: alternative treatment for complete rectal prolapse in high-risk patients.

Background And Aims: Optimal treatment for rectal prolapse is controversial. We describe a novel alternative treatment for high-risk patients with complete rectal prolapse.

Patients And Methods: Sixteen high-risk patients over 60 years old with complete rectal prolapse were examined.

Colonic tuberculosis.

Tubercle bacillus was discovered in 1882 by Robert Koch. With the introduction of chemotherapy for tuberculosis in the 1940s the incidence of this entity decreased. The incidence of the tuberculosis of the colon began to increase at the 1980s with the rise in numbers of patients considered as high risk for this entity, such as HIV-infected individuals, patients with chronic renal disease, and immunosuppressed patients with prolonged steroid therapy.

[Colonic primary lymphoma].

Unlabelled: Primary colon lymphomas (PCL) are very rare tumors of the gastrointestinal tract, and represent 0.2-0.5% of all colon primary tumors.

Endoanal sonography in the assessment of perianal endometriosis with external anal sphincter involvement.

Endoanal sonography can be used in the assessment of benign and malignant anal conditions and to evaluate the anatomy of the anal sphincters. We used endoanal sonography with a 10-MHz rotating endocavitary probe to evaluate a 45-year-old woman with a perianal mass, fecal incontinence, and menses-associated perianal pain. She had had 2 vaginal deliveries requiring episiotomies.
