Cylindrical abdominoperineal

BACKGROUND: The extralevator abdominoperineal resection (ELAPR) is a new surgical technique for patients with low advanced rectal cancer. This technique requires an extra excision of the levator muscles to avoid the surgical waist caused by the conventional abdominoperineal resection, with the patient's position changed to a prone jackknife position and using a myocutaneous flap to repair the pelvic defect. To simplify this operation, we applied a laparoscopic technique to perform controlled transabdominal transection of the levator muscles under direct visualization without a position change and pelvic floor reconstruction using human acellular dermal matrix (HADM)...

PURPOSE: Prone cylindrical abdominoperineal resection (APR) leads to reduced circumferential resection margin (CRM) involvement but is associated with a large perineal deficit. A rectus abdominis myocutaneous (RAM) flap can reduce the morbidity associated with the perineal wound. This is often performed in coordination with a plastic surgeon. We reviewed the outcome of prone APR carried out by a single colorectal surgeon using RAM flap without the involvement of plastic surgeons in a district general hospital...

Extralevator abdominoperineal resection (E-APR) has been advocated as a superior procedure to achieve negative circumferential resection margins (CRMs) for sphincter-invading rectal cancers. An open total mesorectal excision is performed followed by perineal dissection with resection of the levators in the prone position. We describe a novel minimally invasive robotic approach carried out in the lithotomy position. Using the robotic arms to dissect the rectum and divide the levator fibers at their origin, the dissection is carried out in the ischiorectal space as distally as possible...

BACKGROUND: An alternative treatment for low rectal cancer is the cylindrical technique. We aim to compare the outcomes of patients undergoing conventional abdominoperineal resection (APR) versus cylindrical APR. METHODS: A prospective, randomized, open-label, parallel controlled trial was conducted between January 2008 and December 2010. Sixty-seven patients with T3-T4 low rectal cancer were identified during the study period (conventional n = 32, cylindrical n = 35)...

AIM: The study aimed to compare recent reports on standard and alternative methods of abdominoperineal excision for low rectal cancer regarding the rates of circumferential resection margin involvement and intra-operative bowel perforation. METHOD: Data on rates of margin involvement and perforation were obtained from eight recently published reports and also from a prospective registry of resections at Concord Hospital. Rates of these outcomes and their 95% confidence intervals were evaluated...

OBJECTIVE: To evaluate the safety and feasibility of laparoscopic cylindrical abdominoperineal resection. METHODS: Six patients with rectal adenocarcinoma within 3 cm above the anal verge underwent laparoscopic cylindrical abdominoperineal resection. Transabdominal levator transaction was performed laparsocopically, with no position change during the perineal operation. Pelvic reconstruction was achieved using human acellular dermal matrix mesh in 3 patients. RESULTS: All the procedures were successfully performed without any intraoperative complications, laparoscopy-associated complications, or conversion to the open approach...

A 72-year-old female presented with a six-month history of increased frequency of defecation, rectal bleeding, and severe rectal pain. Digital rectal examination and endoscopy revealed a low rectal lesion lying anteriorly. This was confirmed histologically as adenocarcinoma. Radiological staging was consistent with a T(3)N(2) rectal tumour. Following long-course chemoradiotherapy repeat staging did not identify any metastatic disease. She underwent a laparoscopic cylindrical abdominoperineal excision with en bloc resection of the coccyx and posterior wall of the vagina with a negative circumferential resection margin...

INTRODUCTION: An abdominoperineal excision of rectum (APER) may be required for rectal tumours less than 6 cm from the anal verge. Recently, the cylindrical APER has been used to prevent the "surgical waist" and so decrease margin involvement. However, removal of the levators leaves a large defect. Myocutaneous flaps [e.g. vertical rectus abdominis (VRAM)] are often used to fill the cylindrical resection defect, but have disadvantages associated with operative time, expertise and morbidity...

An alternative treatment for low rectal cancer is the extended posterior perineal approach with reconstruction of the pelvic floor (cylindrical technique). Pelvic floor defects often require flap reconstruction using gracilis flaps, vertical rectus abdominis myocutaneous flaps or local fasciocutaneous flap. In this article, the complicated pelvic floor defect was reconstructed with human acellular dermal matrix. Despite a large resection and previous irradiation therapy, the wound healed without complications...

PURPOSE: The extralevator approach to abdominoperineal resection is an emerging surgical option for patients with low rectal cancer. This technique involves a wide excision of the levator muscles that could reduce the high incidence of circumferential margin positivity associated with conventional abdominoperineal resections. We present our technique of robotic cylindrical abdominoperineal resection where the daVinci robot is used to perform a controlled transection of the levator muscles transabdominally under direct visualization...

BACKGROUND: In our own experience over the last 15 years, the primary transpelvic vertical rectus abdominis myocutaneous (VRAM) flap is a reliable tool to prevent perineal wound complications after cylindrical excision in radical anorectal tumor surgery. To minimize the operative trauma in such patients, we performed a laparoscopic abdominoperineal resection combined with an open posterior cylindrical excision and a primary transpelvic vertical rectus abdominis myocutaneous (VRAM) flap via a minimal supraumbilical incision, which is described here for the first time...

Abdominoperineal resection is the one of the oldest surgical procedures for rectal cancer. Outcome after abdominoperineal resection for rectal carcinoma is not as good as anterior resection as the risk of local recurrence is higher and survival is poorer. During abdominoperineal resection, the rate of rectal perforation is high and the circumferential margin is often involved. Recently the concept of cylindrical abdominoperineal resection has been reintroduced. It allows a large excision and the initial results are encouraging...

The improvement of patient carcinological status by an abdominoperineal resection by extended posterior perineal approach in a prone position requires the plastic surgeon to consider other reconstructive options. We present an original double L-shaped free-style propeller flap used to reconstruct the vagina and the perineum of a 57-year-old patient after the resection of a T4 tumour of the lower rectum.

PURPOSE: Patients who undergo cylindrical abdominoperineal resection can have significant complications, especially those who require pelvic reconstruction using myocutaneous flaps. Reconstruction using a biomaterial may be a novel alternative. The purpose of this study is to report the initial results of pelvic reconstruction using human acellular dermal matrix after cylindrical abdominoperineal resection. METHODS: Between January 2008 and February 2009, pelvic floor reconstruction was performed in 12 consecutive patients who underwent cylindrical abdominoperineal resection for advanced ultralow rectal cancer...

BACKGROUND: Over the past several years, preoperative chemoradiotherapy (CRT) has contributed remarkably to make more sphincter-preserving procedure (SPP) possible for lower rectal cancer. The aim of this study was to compare the outcomes between abdominoperineal resection (APR) and SPP after preoperative CRT in patients with locally advanced lower rectal cancer. METHODS: A retrospective investigation was conducted with a total of 122 patients who underwent radical surgery combined with preoperative CRT for locally advanced lower rectal cancer...

PURPOSE: Abdominoperineal excision (APE) of the rectum and anus for rectal cancer continues to have greater local recurrence and poorer survival than that seen following anterior resection. Changing to an extended prone perineal dissection results in a more cylindrical specimen and should improve outcomes. PATIENTS AND METHODS: One hundred twenty-eight specimens from patients who underwent APE that was performed for potentially curable primary rectal adenocarcinoma were dissected according to standard protocol in Leeds and Stockholm between 1997 and 2007 and were studied...

PURPOSE: Duplications of the rectum are extremely rare embryologic events, with almost 70 cases reported in the world literature. We report on a 39-year-old female patient with a duplication of the rectum. METHODS: Physical examination showed a left buttock mass; rectal examination revealed the presence of a painless mass compressing the rectum posterolaterally, confirmed by computerized tomography. RESULTS: The patient was operated on with a abdominal then a sacrococcygeal approach...
