[Colorectal anastomosis using a compression device].

Background: The most severe complication following an intestinal anastomosis is the dehiscence with the consequent development of sepsis, fistulas, stenosis, and death. For this reason the compression anastomosis (NiTi) system was developed, with the aim of reducing these complications.

Material And Methods: A retrospective study was conducted, from 1 June 2012 to 30 August 2014, on total of 14 patients operated on the Humanitas Hospital Medical Group Coyoacán, the ASMED, and Clínica Médica Sur.

[Rectal perforation as a result of stapled hemorrhoidectomy].

Background: The procedure for prolapsing hemorrhoids (PPH) has the potential to overcome many of the disadvantages of excisional hemorrhoidectomy; nevertheless, rare serious postoperative complications have been reported.

Clinical Case: We present a case of a 31-year-old male who was admitted and treated at another hospital with a stapled mucosectomy, which was carried out using a PPH01 33-mm stapling device. During the immediate postoperative period a fistula presented from the rectum to the right gluteus and a primary closure was attempted.

Interposition of gracilis muscle for rectourethral fistula repair: case report.

Background: Rectourethral fistula is a rare disease with a difficult surgical treatment. The etiology of rectourethral fistula is iatrogenic, secondary to prostate surgery, pelvic radiotherapy and a rare complication of rectal surgery. Surgical treatment options for rectourethral fistula are diverse.

[Experience in surgical management of rectal prolapse in two hospitals in Mexico City].

Background: Rectal prolapse is defined as a falling out of place of the rectum through anus. Surgery is the treatment of choice to reverse abnormal anatomy and to improve anorectal function.

Objective: To review the experience in recent years of surgical management of rectal prolapse in the Hospital Central Militar and Instituto Nacional de Ciencias Medicas y Nutrición Salvador Zubiran.

[Synchronous diverticulitis: a case report.].

Diverticular colonic disease is not as common in developing nations as in western and industrialized societies, accounting for approximately 130 000 hospitalizations per year in the United States, being diverticulitis the most frequent complication. Synchronous presentation of this complication is very rare, with only one case reported in literature. We present a patient who presented with diffuse abdominal pain.

Prevalence and clinical features of indeterminate colitis in Mexico: a 17-year study.

Background: Indeterminate Colitis (IC) is diagnosed after colectomy when macroscopic and microscopic features were not sufficient to allow a definite diagnosis of either the classical types of Ulcerative Colitis (UC) or Crohn's disease (CD). Epidemiological data from some series have reported that IC is diagnosed in between 9% and 20% of colectomy specimens.

Aim: To determine the prevalence of IC in Mexican patients and to describe their clinical features.

Transposition of gracilis muscle for treatment of recurrent anal and rectovaginal fistula.

Background: Rectovaginal fistula is defined as a result of an abnormal connection between the rectum and vagina. It is often a result of inflammatory bowel disease, iatrogenic illness, malignancy or trauma. Rectovaginal fistula treatment is dependent on the classification of the fistula (simple or complex).

[Hereditary non-polyposis colorectal cancer associated with hereditary gastric cancer. A case report.].

The information regarding the association of gastric cancer and type 2 Lynch syndrome is limited. Previous studies have reported that both entities may be present in the same individual in less than 5% of the cases. The most frequent form of hereditary colorectal cancer is the Lynch syndrome or Hereditary Non-polyposic Colorectal Cancer, which is associated with germ-line mutation mostly of two genes, MLH1 and MSH2, which account for almost 90 percent of all identified mutations.

[Pelvic angiomyxoma. A case report from National Institute of Medical Sciences and Nutrition, Salvador Zubiran.].

An angiomyxoma is a pelvic neoplasia compound of myofibroblasts. This is a case report of a 41 years old female patient, who presented with a painful, pelvic mass, identified by a tomography with malignant characteristics. Total surgical excision was performed and coursed with good evolution time.

[Factors associated with survival in liver resection for metastatic colorectal carcinoma].

Background: The liver is the organ in which often metastasize primary tumors. Knowledge of the etiology and forms of presentation of metastatic disease is key to deciding on the different treatment options.

Objective: Describe the surgical management of liver metastases in colorectal cancer and factors that affect the survival of patients.

[Laparoscopic colorectal surgery: third level center experience.].

Background: The role of laparoscopic surgery in the management of colorectal pathologies is steal unclear. Some new evidence has shown some advantages over open procedures. Because it is a technically demanding procedure, the progress is very low, and used among few colorectal surgeons.

Laparoscopic total proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis: initial experience in Mexico.

Background: Since the introduction of laparoscopic colectomy in 1991, experience in laparoscopic bowel surgery has gradually increased. Several reports from specialized centers have demonstrated that laparoscopic colorectal resections are feasible and safe, providing an acceptable alternative to laparotomy for a variety of diseases. Some studies have shown the feasibility, safety, and good functional outcome of the minimally invasive procedures for ulcerative colitis (UC) and familial adenomatous polyposis (FAP).
