Purse string closure of perineal defects after abdominoperineal excision.

PURPOSE: The aim of this study was to describe a new technique of perineal closure following abdominoperineal excision (APE) using purse-string perineal skin closure (PSPC). MATERIAL AND METHODS: Between January 2016 and May 2021, 15 consecutives patients who had an APE procedure were included in this retrospective single-center study. All indications of APE were considered, as well as all types of APE. We analyzed the patient characteristics and peri-operative features, including overall (Clavien 1 to 5) and severe (Clavien 3 and 4) postoperative morbidity, length of stay (LOS), and long-term results (median time to perineal wound closure and rate of perineal incisional hernia). RESULTS: The patients included 11 men and four women, with a mean age of 64 ± 13 [33-80] years. The indication of APE was an epidermoid carcinoma of the anal canal (n = 5) or an adenocarcinoma of the rectum (n = 10). The mean operating time was 220 ± 88.64 [70-360] min. The overall morbidity rate was 60%, the severe morbidity rate 26%, and reoperation rate 26%. The median length of stay was 9 ± 6.5 days. After a mean follow-up of 23.5 ± 20.3 months, the median time to perineal wound closure was 96 ± 60 days, the persistent perineal sinus rate was 6% (n = 2), and one patient developed a perineal incisional hernia. CONCLUSION: Purse-string closure of perineal wounds is a safe and effective technique for perineal wound closure after APE. The short LOS allowed an early return home.

Incidental discovery of a sacral rib: a case report.

PURPOSE: The observation of an accessory bone joined to the sacrum (suggestive of a sacral rib) prompted us to describe the structure's morphology and its anatomic relationships and to consider its morphogenesis and clinical implications. METHOD: A 38-year-old woman underwent computed tomography, to characterize the extension of a thoracic mass. We compared our observations with the literature data. RESULTS: We observed a voluminous accessory bone located behind and to the right of the sacrum. The bone was articulated with the third sacral vertebra and featured a head and three processes. These characteristics were suggestive of a sacral rib. We also observed involution of the gluteus maximus. CONCLUSION: This accessory bone probably resulted from overdevelopment of a costal process and an absence of fusion with the primitive vertebral body. Sacral ribs are rare and usually asymptomatic but appear to be more prevalent in young women. The adjacent muscles are often abnormal. Awareness of the potential presence of this bone is essential for surgeons who operate on the lumbosacral junction.
