[Robot assisted Frykman-Goldberg procedure. Case report].

Background: Rectal prolapse is defined as the protrusion of the rectal wall through the anal canal; with a prevalence of less than 0.5%. The most frequent symptoms include pain, incomplete defecation sensation with blood and mucus, fecal incontinence and/or constipation.

[Initial experience in robot-assisted colorectal surgery in Mexico].

Background: Colorectal surgery has advanced notably since the introduction of the mechanical suture and the minimally invasive approach. Robotic surgery began in order to satisfy the needs of the patient-doctor relationship, and migrated to the area of colorectal surgery. An initial report is presented on the experience of managing colorectal disease using robot-assisted surgery, as well as an analysis of the current role of this platform.

[Elective laparoscopic right colectomy for caecal volvulus: case report and literature review].

Background: Caecal volvulus is an uncommon cause of intestinal obstruction. Its clinical presentation is non-specific, with the diagnosis usually confirmed by barium enema and abdominal computed tomography. Treatment depends on many factors, and minimally invasive approaches are becoming the treatment of choice.

[Biofeedback effectiveness in patients with fecal incontinence].

Background: Fecal incontinence is defined as an involuntary bowel movement through the anal canal in inadequate time and place. There are different types of therapies for the management of fecal incontinence, being biofeedback therapy one of the most effective techniques. The aim of this study was to evaluate the necessary number of sessions of biofeedback electromyographyc therapy to achieve the maximum sphincteric complex contraction.

Appendiceal diverticulum associated with chronic appendicitis.

Introduction: Appendiceal diverticulosis is a rare entity, with a global incidence between 0.004% and 2.1% of all appendectomies.

[Pseudomyxoma peritonei. Two-case-report].

Background: Pseudomyxoma peritonei is a disease characterized by an intraperitoneal adenomucinous tumor cell disemination, being cecal appendix the most common etiology.

Objective: To report a surgeon's group experience and a detailed up to date literature review.

Clinical Cases: 1.

Colonic tuberculosis in an immunocompetent patient.

Introduction: One-third of the world's population is infected with tuberculosis (TB), with intestinal TB representing the sixth most common presentation of extrapulmonary TB. The diagnosis of intestinal TB is a challenge for physicians due to its diverse clinical manifestations that mimic other infectious, autoimmune, and neoplastic disorders, and is thus rarely considered as the causative agent of disease.

Presentation Of Case: We present a 55-year-old male with no relevant familial history, who presented due to a loss of 10kg of weight in 2 months accompanied by nocturnal diaphoresis and continuous abdominal distension.

[Acute appendicitis without Crohn's disease in a patient with inflammatory bowel disease. Case report].

Background: Crohn's disease was described for the first time in 1932. The association of acute appendicitis with this disease is very rare and when the cecum is involved, risk of fistula is very high.

Case Report: We present the case of a 48-year-old female who had been diagnosed with Crohn's disease several months earlier.

[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.

[Anorectal tuberculosis. Case report].

Objective: To report for the first time in Mexico a case of anorectal tuberculosis as well as the revision of world-wide literature.

Background: In recent years the tuberculosis has had a significant increase, caused mainly by the epidemic of acquired immunodeficiency syndrome. The anorectal tuberculosis is a very rare presentation, their diagnosis requires a high index of suspicion since it can be confused with an infectious disease.

[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.

[Rectal diverticula. Case report].

Background: The presence of rectal diverticula is extremely rare; nevertheless, diverticular disease is considered a greater problem. We report a case of rectal diverticula in a patient with diverticular disease of the sigmoid.

Clinical Case: An 88-year-old male presented to the emergency room with hematochezia of several days evolution.

[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.
