BACKGROUND The treatment of chronic anal fissure has shifted in recent years from surgical to medical. METHODS A Medline search of studies relevant to modern management of chronic anal fissure was undertaken. RESULTS Traditional surgery that permanently weakens the internal sphincter is associated with a risk of incontinence. Medical therapies(More)
BACKGROUND There have recently been reports of higher levels of bladder and sexual dysfunction in men after laparoscopic rectal surgery when compared with those undergoing open surgery. This has led some surgeons to question the role of the laparoscopic approach to rectal surgery. METHOD This study represents a retrospective analysis of a prospectively(More)
BACKGROUND Self-expanding metallic stents (SEMS) may be used in acute obstructing left-sided colonic cancers to avoid high-risk emergency surgery. However, oncological safety remains uncertain. This study evaluated the long-term oncological outcome of SEMS as a bridge to elective curative surgery versus emergency resection. METHODS A consecutive(More)
PURPOSE New-generation multi-instrument ports for laparoscopic surgery now allow abdominal surgery via a single-access small incision. Here, we detail how laparoscopic total colectomy can be safely performed within the constraints of such single site operating. METHODS Three patients (2 males and 1 female; mean age, 28.3 y; mean body mass index, 24.1(More)
Anastomotic leakage is a devastating complication of colorectal surgery. However, there is no technology indicative of in situ perfusion of a laparoscopic colorectal anastomosis. We detail the use of near-infrared (NIR) laparoscopy (PinPoint System, NOVADAQ, Canada) in association with fluorophore [indocyanine green (ICG), 2.5 mg/ml] injection in 30(More)
AIM Although high-grade internal rectal prolapse is believed to cause functional symptoms such as obstructed defaecation, little has been published on the exact distribution and frequency of symptoms. The aim of this study was to identify the most common symptoms of patients with high-grade internal rectal prolapse. METHOD Patients were diagnosed with(More)
AIM Anismus causes obstructed defecation as a result of inappropriate contraction of the puborectalis/external sphincter. Proctographic failure to empty after 30 s is used as a simple surrogate for simultaneous electromyography/proctography. Botulinum toxin is theoretically attractive but efficacy is variable. We aimed to evaluate the efficacy of botulinum(More)
High-grade internal rectal prolapse appears to be one of the contributing factors in the multifactorial origin of faecal incontinence. Whether it affects the outcome of sacral neuromodulation is unknown. We compared the functional results of sacral neuromodulation for faecal incontinence in patients with and without a high-grade internal rectal prolapse.(More)
BACKGROUND Botulinum toxin heals only approximately one-half of glyceryl trinitrate-resistant chronic anal fissures, perhaps because chemical sphincterotomy alone treats internal sphincter spasm but not chronic fissure fibrosis. We aimed to assess whether a novel procedure, fissurectomy-botulinum toxin, improves the healing rate of medically resistant(More)
