RESUMEN
Abstract Purpose: The benefits of laparoscopic approaches to treat colorectal cancer (CRC) and colorectal liver metastases (CRLM) separately are well established. However, there is no consensus about the optimal timing to approach the primary tumor and CRLM, whether simultaneously or staged. The objective of this review with practical reports is to discuss technical aspects required for patient selection to perform simultaneous laparoscopic approaches for CRC and CRLM. Methods: Literature review of oncological factors associated with patient selection for surgical treatment of CRLM and the use of laparoscopy in those cases, and report of technical aspects for simultaneous CRC and CRLM approaches. Results: Simultaneous laparoscopic resection has been successful in many series of selected patients, although it seems to be safer to perform minor and major liver resection with non-extended colorectal resections, and to avoid two high-risk procedures at the same time. Conclusions: Simultaneous CRC and CRLM resections seem to be safe when patients are carefully selected, also considering the risk of recurrence concerning oncologic outcomes. The pre-planning of simultaneous resection is mandatory to plan trocar positioning, procedure sequencing, and patient position.

INTRODUÇÃO: A ritidoplastia se tornou uma das cirurgias estéticas mais realizadas por cirurgiões plásticos ao redor do mundo. Junto com o aumento do número de cirurgias, a quantidade de complicações associadas ao procedimento também aumentou, sendo que as alterações nervosas são uma das que despertam maiores preocupações. O presente estudo visa a identificar, por meio de uma revisão sistemática, as principais estruturas nervosas lesadas durante uma ritidoplastia, tanto por técnicas convencionais como endoscópicas. MÉTODOS: Uma revisão sistemática da literatura foi realizada nas principais bases de dados utilizadas atualmente. Artigos que preencheram os critérios de inclusão foram analisados na íntegra e suas referências, verificadas. Ao final, 20 estudos foram incluídos. RESULTADOS: Nestes 20 artigos, no total, foram avaliados 3.347 pacientes, sendo encontradas 142 lesões nervosas: 79 do nervo facial; 55 do nervo trigêmeo, e oito do nervo auricular magno. Destas, apenas duas foram definitivas. As lesões, proporcionalmente, foram mais comuns nas técnicas videoassistidas (81%), quando comparadas com as convencionais (19%). CONCLUSÃO: Encontramos que as lesões dos ramos temporal e bucal são mais frequentes no facelift e as do nervo auricular magno, na ritidoplastia cervical. Apesar de as lesões nervosas serem pouco frequentes na literatura, faltam estudos bem desenhados que busquem conhecer melhor estas complicações.
INTRODUCTION: Rhytidoplasty has become one of the most common aesthetic surgeries performed by plastic surgeons worldwide. Along with the increase in the number of surgeries performed, the number of procedure-related complications has also increased. In particular, nerve injuries are the major concern. By conducting a systematic review, the present study aimed to identify the main nerve structures injured during rhytidoplasty, by either the conventional or endoscopic technique. METHODS: A systematic literature review was performed in the main databases currently used. Articles that met the inclusion criteria were analyzed in their entirety, and their references were checked. Finally, 20 studies were included. RESULTS: In these 20 articles, 3,347 patients were evaluated and 142 nerve injuries found, of which 79 were of the facial nerve, 55 were of the trigeminal nerve, and eight were of the great auricular nerve. Of these, only two were definitive. The lesions were more prevalent (81%) with the video-assisted techniques than with the conventional techniques (19%). CONCLUSION: We found that the injuries of the temporal and buccal branches were more frequent during facelifts; and those of the great auricular nerve, during cervical rhytidoplasty. Although nerve injuries are infrequent in the literature, well-designed studies that aim to better understand these complications are lacking.
