Laparoscopic proctocolectomy with restorative ileal-anal pouch.

OBJECTIVE: The aim of the study was to analyse the outcome of restorative proctocolectomy carried out by laparoscopic surgery. METHODS: A prospectively collected electronic database of all colorectal laparoscopic procedures performed between April 2001 and July 2003 has been used to identify surgical outcomes in 14 consecutive patients who have undergone laparoscopic RPC. RESULTS: Fourteen patients (5 male), median BMI 24 kg/m(2) have undergone restorative laparoscopic proctocolectomy over a two year period: 13 (ulcerative colitis, one with cancer) and 1 (FAP). The median operation time was 260 min; time has not decreased with experience. There were no intra-operative surgical complications or deaths. Patient controlled analgesia continued for a median of 36 h. The median time to diet was 48 h and median hospital stay 7 days; three patients required nasogastric aspiration for delayed gastric emptying. Eighteen regional lymph nodes were retrieved local to the carcinoma. There was one anastomotic leak. All covering stomas were closed by 6 months (12 by eight weeks). All 14 patients are fully continent, able to suppress urgency and have a median pouch frequency of 4/24 h. None admit to having problems with potency, orgasm sensation, ejaculation, micturition. One lady reports dysparunia. All are highly satisfied with functional outcome and cosmesis. CONCLUSION: We are encouraged to continue to offer our patients the option of a laparoscopic resection.

Fecal incontinence in scleroderma: assessment of the anal sphincter with thin-section endoanal MR imaging.

PURPOSE: To compare the magnetic resonance (MR) imaging appearance of the anal sphincter in patients with fecal incontinence and scleroderma with that in patients with fecal incontinence alone, scleroderma alone, or neither. MATERIALS AND METHODS: The study population comprised 14 patients with fecal incontinence and scleroderma, four with scleroderma alone, 13 with incontinence alone, and six with neither. T1- and T2-weighted spin-echo, magnetization transfer contrast-weighted, and dynamic gadolinium-enhanced images were obtained and analyzed for the integrity, thickness, and length of sphincter components. Magnetization transfer contrast ratios and T2 were calculated to assess fibrosis of the internal sphincter. The percentage enhancement above baseline was calculated at 30-second intervals for the internal and the external sphincter. RESULTS: Eleven patients with incontinence and scleroderma showed descent of rectal air and feces into the anterior anal canal, with forward deviation of the significantly (P < .05) atrophied internal sphincter, which showed a slower gadolinium-enhancement pattern compared with that in other groups. Patients with incontinence alone showed no evidence of internal sphincter deviation or altered vascularity but had a significant reduction (P < .05) in deep external sphincter bulk. CONCLUSION: In patients with fecal incontinence and scleroderma, endoanal MR imaging helps delineate the anterior sphincter deformity and shows the slower gadolinium-enhancement pattern on dynamic studies of the internal sphincter.

Hand-assisted laparoscopic colorectal surgery.

Hand-assisted laparoscopic surgery is a newly developed technique. It involves the intra-abdominal placement of a hand or forearm through a mini laparotomy incision while pneumoperitoneum is maintained. This way, the hand can be used as in an open procedure to palpate organs or tumours, reflect organs atraumatically, retract structures, identify vessels, dissect bluntly along a tissue plain, and provide finger pressure to bleeding points while proximal control is achieved. Additionally this approach is more economical than a totally laparoscopic approach, reducing both the number of laparoscopic ports and number of instruments required. Some advocates of the technique claim that it is also easier to learn and perform than totally laparoscopic approaches, and that there may be increased patient safety.

Transanal endoscopic microsurgery.

Transanal endoscopic microsurgery, although technically challenging, offers a viable and perhaps superior outcome to radical abdominal or traditional transanal excision of rectal neoplasia. Appropriate training and case selection, as with any new technology, are mandatory to help ensure optimal results.
