Pedicled vastus lateralis musculofascial flap as a new technique for repairing rectourethral fistula after radical prostatectomy

A New Technique to Repair Vesicorectal Fistula: Overlapping Rectal Muscle Plasty by Transanal Endoscopic Surgery

OBJECTIVE

To evaluate clinical results of a novel surgical technique, we developed to repair vesicorectal fistula (VRF) occurring after prostatectomy, hospital records of the patients, who underwent the new surgical treatment, were assessed.

METHODS

The novel surgical technique is called "overlapping rectal muscle plasty," which is performed under transanal endoscopic microsurgery (TEM). During the new procedure, a complete fistulectomy was first performed, and then the proper muscle layer of the rectum was folded, overlapped, and sutured to create a thick wall between the rectum and urinary bladder. This operation was carried out in 15 patients with VRF following radical prostatectomy.

RESULTS

The operation was safely performed in all patients with an average time of 127.2 min. Fistula was corrected in 13 patients (86.7%), who were then freed from both urinary and intestinal diversions.

CONCLUSIONS

Overlapping rectal muscle plasty by TEM is a safe procedure. The success rate seems to be acceptable in selected patients. This new repair method may be considered as a minimally invasive option in the surgical treatment of VRF after prostatectomy.

Vastus lateralis myocutaneous flap for ischial skin wound following the treatment of epithelioid sarcoma using pazopanib

Pazopanib, a targeted molecular drug, has been proposed as an effective treatment for soft tissue tumour and as a novel adjuvant therapy. There has been a paradoxical concern that wound healing could be inhibited by its anti-angiogenic properties, especially in reconstructive surgery. This paper reports on a 28-year-old woman who underwent flap surgery due to a skin and soft tissue injury after an effective treatment with pazopanib for refractory epithelioid sarcoma. The flap survived without any complication in off-periods of pazopanib for four weeks before and after the surgery, although it is only recommended that the washout periods of pazopanib commence at least seven days before scheduled surgery.

Limitations of the Vastus Lateralis Muscle as a Substitute for Lost Abductor Muscle Function: An Anatomical Study

Abductor insufficiency after hip arthroplasty resulting from an impaired gluteus medius and minimus remains an unsolved problem in orthopaedic surgery. The vastus lateralis (VL) was described as a functional substitute for abductor insufficiency in 2004. We carried out a macrodissection of twelve cadaveric hemipelvises to investigate the innervation of the VL and adjacent muscles to assess the extent the VL can be safely transferred. Results showed that direct muscle branches to proximal portions of the VL are too short to allow a significant shift; the shift may be as small as 13 mm. Nerves that supply the VL also extend to the vastus intermedius. This innervation pattern makes it impossible to shift the VL significantly without damaging branches to both.

Acquired recto-uretral fistulas: etiopathogenesis, diagnosis and therapeutic options

Rectouretral fistulas are a rare disease, but represent an important problem for the patient that suffers them and a challenge for the urologist and colorectal surgeon who has to manage them. A wide review has been performed focusing on etiopathogenic factors, diagnostic and therapeutic options including the analysis of different surgical techniques. PubMed, MEDLINE y EMBASE medical database were searched up to September 2014.
