Abstract We report our experience and results in the management of Fourniers gangrene. Fourniers gangrene is a synergistic infective necrotizing fasciitis, which involves perianal, perineal and genital regions, originated mostly from colorectal and genitourinary sources. Charts and records from 28 patients with Fourniers gangrene diagnosed between 1993 and 1997 were reviewed. The mean patients age was 57.8 years (range, 22–82 years); mean hospital stay was 19 days. Eighteen patients (64.3%) were diabetic. The most common source of gangrene was ischiorectal abscess in 22 patients (78.6%). Colostomy was performed on 14 patients (50%) and cystostomy on 7 patients (25%). Ten patients (35.7%) died because of sepsis. In conclusion, medical and surgical treatment should be aggressive. Colostomy should only be performed if sphincter complex is damaged. Multidisciplinary management is mandatory, because of high morbidity and mortality.

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. The surgical approach can be perineal or abdominal with the tendency for minimal invasion. Robot-assisted procedures are a novel option that offer technique advantages over open or laparoscopic approaches. CASE REPORT 67 year-old female, who presented with rectal prolapse, posterior to an episode of constipation, that required manual reduction, associated with transanal hemorrhage during defecation and occasional fecal incontinence. A RMI defecography was performed that reported complete rectal and uterine prolapse, and cystocele. A robotic assisted Frykman-Goldberg procedure wass performed. DISCUSSION There are more than 100 surgical procedures for rectal prolapse treatment. We report the first robot assisted procedure in Mexico. Robotic assisted surgery has the same safety rate as laparoscopic surgery, with the advantages of better instrument mobility, no human hand tremor, better vision, and access to complicated and narrow areas. CONCLUSION Robotic surgery as the surgical treatment is a feasible, safe and effective option, there is no difference in recurrence and function compared with laparoscopy. It facilitates the technique, improves nerve preservation and bleeding. Further clinical, prospective and randomized studies to compare the different minimal invasive approaches, their functional and long term results for this pathology are needed.

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. MATERIAL AND METHODS A retrospective study was conducted in order to review five patients with colorectal disease operated using a robot-assisted technique over one year in the initial phase of the learning curve. Gender, age, diagnosis and surgical indication, surgery performed, surgical time, conversion, bleeding, post-operative complications, and hospital stay, were analysed and described. A literature review was performed on the role of robotic assisted surgery in colorectal disease and cancer. RESULTS The study included 5 patients, 3 men and 2 women, with a mean age of 62.2 years. Two of them were low anterior resections with colorectal primary anastomoses, one of them extended with a loop protection ileostomy, a Frykman-Goldberg procedure, and two left hemicolectomies with primary anastomoses. The mean operating time was 6hours and robot-assisted 4hours 20minutes. There were no conversions and the mean hospital stay was 5 days. CONCLUSION This technology is currently being used worldwide in different surgical centres because of its advantages that have been clinically demonstrated by various studies. We report the first colorectal surgical cases in Mexico, with promising results. There is enough evidence to support and recommend the use of this technology as a viable and safe option.
