RESUMO
PURPOSE: No standard exists for reconstruction after extralevator abdominoperineal excision (ELAPE) and pelvic exenteration. We propose a tailored concept with the use of bilateral gluteal V-Y advancement flaps in non-extended ELAPE and with vertical myocutaneous rectus abdominis muscle (VRAM) flaps in extended procedures. This retrospective study analyzes the feasibility of this concept. PATIENTS AND METHODS: We retrieved all consecutive patients after ELAPE or pelvic exenteration for rectal, anal, or vulva cancer with flap repair from a prospective database. Perineal wound complications were defined as the primary endpoint. Outcomes for the two different flap reconstructions were analyzed. RESULTS: From 2005 to 2021, we identified 107 patients who met the study criteria. Four patients underwent exenteration with VRAM flap repair after previous V-Y flap fashioning. Therefore, we report on 75 V-Y and 36 VRAM flaps. The V-Y group contained more rectal carcinomas, and the VRAM group exhibited more patients with recurrent cancer, more multivisceral resections, and longer operation times. Perineal wound complications occurred in 21.3% in the V-Y group and in 36.1% in the VRAM group (p = 0.097). Adjusted odds ratio for perineal wound complication was not significantly different for the two flap types. CONCLUSION: Concerning perineal wound complications, our concept yields favorable results for V-Y flap closure indicating that this less invasive approach is sufficient for non-extended ELAPE. Advantages are a shorter operation time, less donor site morbidity, and the option of a second repair. VRAM flaps were reserved for larger wounds after pelvic exenteration or vaginal repair.

Sapovirus enteric disease affects people of all ages across the globe, in both sporadic cases and outbreak settings. Sapovirus is seldom assessed in Germany and its epidemiology in the country is essentially unknown. Thus, sapovirus occurrence and genetic diversity were studied by real-time reverse transcription polymerase chain reaction (RT-PCR) and partial sequencing of major viral structural protein (VP1) gene in two different sets of stool samples: 1) a selection of 342 diarrheal stools collected from inpatient children during 2008-2009, and 2) 5555 stool samples collected during 2010-2018 from inpatients of all age groups with gastrointestinal complaints. Results showed year-round circulation of sapoviruses, with peaks during cooler months. In total, 30 samples (8.8%) of the first and 112 samples of the second set of samples (2.0%) were sapovirus positive. Capsid gene sequencing was successful in 134/142 samples (94.4%) and showed circulation of all known human pathogenic genogroups. Genotype GI.1 predominated (31.8%), followed by GII.1 (16.7%), GII.3 (14.5%), GI.2 (13.8%) and GV.1 (12.3%). Additionally, minor circulation of GI.3, GI.6, GII.2, GII.4, GII.6 and GIV.1 was shown. Consequently, sapovirus diagnostics need broadly reactive RT-PCR protocols and should particularly be considered in infants and young children. Further studies from other sampling sites are essential to extend our knowledge on sapovirus epidemiology in Germany.
