A comparative multicentre study evaluating gluteal turnover flap for wound closure after abdominoperineal resection for rectal cancer.

BACKGROUND: The aim of this study was to compare perineal wound healing between gluteal turnover flap and primary closure in patients undergoing abdominoperineal resection (APR) for rectal cancer. METHODS: Patients who underwent APR for primary or recurrent rectal cancer with gluteal turnover flap in two university hospitals (2016-2021) were compared to a multicentre cohort of primary closure (2000-2017). The primary endpoint was uncomplicated perineal wound healing within 30 days. Secondary endpoints were long-term wound healing, related re-interventions, and perineal herniation. The perineal hernia rate was assessed using Kaplan Meier analysis. RESULTS: Twenty-five patients had a gluteal turnover flap and 194 had primary closure. The uncomplicated perineal wound-healing rate within 30 days was 68% (17/25) after gluteal turnover flap versus 64% (124/194) after primary closure, OR 2.246; 95% CI 0.734-6.876; p = 0.156 in multivariable analysis. No major wound complications requiring surgical re-intervention occurred after flap closure. Eighteen patients with gluteal turnover flap completed 12-month follow-up, and none of them had chronic perineal sinus, compared to 6% (11/173) after primary closure (p = 0.604). The symptomatic 18-month perineal hernia rate after flap closure was 0%, compared to 9% after primary closure (p = 0.184). CONCLUSIONS: The uncomplicated perineal wound-healing rate after the gluteal turnover flap and primary closure after APR is similar, and no chronic perineal sinus or perineal hernia occurred after flap closure. Future studies have to confirm potential benefits of the gluteal turnover flap.

Pilonidal sinus laser-assisted closure (PiLAC) - a low-morbidity alternative to excision with excellent long-term outcomes.

INTRODUCTION: Recurrence after surgery for pilonidal sinus disease is a recognised problem and patients often re-present months after discharge. We routinely treat primary and recurrent pilonidal sinus disease with Pilonidal sinus Laser-Assisted Closure (PiLAC). Long-term outcomes following PiLAC surgery was examined following clinical and telephone review. METHODS: All patients undergoing PiLAC as a day-case between April 2016 and July 2019 were included. Patients were followed up in a nurse-led clinic until complete healing or recurrence. A prospective database and retrospective audit of notes combined with longer-term follow-up by telephone were used. RESULTS: A total of 35 patients underwent PiLAC, median age 28 (18-53 years), 28 males:7 females. A total of 28 patients had long-term (>60 days) follow-up, mean 407 days (range 67-887 days); 25/28 patients (89.3%) had healed with no recurrence on long-term follow-up. Of these 28 patients, 11 were first presentation of pilonidal disease and underwent PiLAC as their first treatment, with a 91% heal rate long term. A total of 15 patients had seton drainage prior to PiLAC, with a 93% heal rate versus no seton (83%). Fisher's exact test showed no significant difference between sex, new/recurrent pilonidal disease and seton placement (p>0.05). CONCLUSIONS: Healing after PiLAC for the treatment of primary and recurrent pilonidal sinus disease is preserved with excellent long-term outcomes. We recommend it as an alternative to surgical excision.

Right upper quadrant pain and raised alkaline phosphatase is not always a hepatobiliary problem.

Right upper quadrant pain is a common presenting complaint to the general and hepatobiliary surgical team. Differential diagnoses include gallstones, cholecystitis, liver and pancreatic pathology. A 64-year-old man presented to our general surgical unit with right upper quadrant pain and deranged liver function tests. He underwent ultrasonography several times as well as magnetic resonance cholangiopancreatography (MRCP) in pursuit of hepatobiliary pathology. However, it was the identification of an empyema on MRCP that led to computed tomography of the thorax and the eventual discovery of the cause of the pain: a paraspinal abscess causing T10/T11 discitis. Right upper quadrant pain and deranged liver function tests justify hepatobiliary investigation. Nevertheless, after several negative tests, the differential diagnoses should be broadened and referred pain considered.
