Ressecões hepáticas por videolaparoscopia

Laparoscopic hepatectomy: indications and results from 18 resectable cases

OBJECTIVE

To evaluate the early and late results from laparoscopic hepatectomy procedures at a tertiary hospital in Brasília (DF), Brazil.

METHODS

The authors report on a series of 18 patients (11 women) who underwent laparoscopic hepatectomy performed by a single surgical team at Santa Lúcia Hospital, in Brasília, between June 2007 and December 2010. Age ranged from 21 to 71 years (median = 43 years). There were eleven women and seven men. Nine patients had benign diseases and nine had malignant lesions. The lesion diameter ranged from 1.8 to 12 cm (mean: 4.96 cm).

RESULTS

Six major hepatectomy procedures and 12 minor hepatectomy procedures were performed. The mean duration of the operation was 205 minutes (range: 90 to 360 minutes). The mean intraoperative blood loss was 300 mL (range: 100 to 1,500 mL). Two patients received a transfusion (11%). There was one conversion to open surgery. There was no death and no patient underwent reoperation. The postoperative morbidity rate was 11% (n = 2). One patient presented with a minor complication (lobar pneumonia) while other presented with two major complications (intraoperative bleeding and incisional hernia). The median length of hospital stay was 4 days (range: 2 to 11 days). The median time to return to normal activities was 13 days (range: 7 to 40 days).

CONCLUSION

Laparoscopic hepatectomy is a safe surgical approach for treating both benign and malignant hepatic lesions. This small series showed no mortality, low morbidity and good cosmetic results.

Video assisted resections. Increasing access to minimally invasive liver surgery?

Objective: To evaluate perioperative outcomes, safety and feasibility of video-assisted resection for primary and secondary liver lesions. Methods : From a prospective database, we analyzed the perioperative results (up to 90 days) of 25 consecutive patients undergoing video-assisted resections in the period between June 2007 and June 2013. Results : The mean age was 53.4 years (23-73) and 16 (64%) patients were female. Of the total, 84% were suffering from malignant diseases. We performed 33 resections (1 to 4 nodules per patient). The procedures performed were non-anatomical resections (n = 26), segmentectomy (n = 1), 2/3 bisegmentectomy (n = 1), 6/7 bisegmentectomy (n = 1), left hepatectomy (n = 2) and right hepatectomy (n = 2). The procedures contemplated postero-superior segments in 66.7%, requiring multiple or larger resections. The average operating time was 226 minutes (80-420), and anesthesia time, 360 minutes (200-630). The average size of resected nodes was 3.2 cm (0.8 to 10) and the surgical margins were free in all the analyzed specimens. Eight percent of patients needed blood transfusion and no case was converted to open surgery. The length of stay was 6.5 days (3-16). Postoperative complications occurred in 20% of patients, with no perioperative mortality. Conclusion : The video-assisted liver resection is feasible and safe and should be part of the liver surgeon armamentarium for resection of primary and secondary liver lesions.

Scarless hepatectomy: natural orifice specimen extraction after left lateral sectionectomy

BACKGROUND

The use of laparoscopy in liver surgery is well established and considered as the gold standard for small resections. The laparoscopic resections have lower morbidity and better cosmetic results, but still require an incision to remove the surgical specimen. The possibility of remove the specimen through natural orifices and avoid an abdominal incision may further improve the benefits offered by minimally invasive procedures.

AIM

To describe the technique of transvaginal extraction of the specimen after laparoscopic liver left lateral sectionectomy.

METHOD

The laparoscopic liver resection is performed in a standard fashion. After completing the resection, the specimen is placed into a retrieval plastic bag. To perform de extraction, a vaginal colpotomy is performed, guided by a 12 mm trocar introduced through the vagina. Then the extraction bag is removed pulling the bag through the extended incision in the posterior wall of the vagina. After the extraction, the colpotomy incision is closed laparoscopically.

RESULTS

This technique was performed in a 74-year-old woman with a 3 cm lesion between liver segments 2 and 3. She had a fast and uneventful recovery.

CONCLUSION

This technique appears to be feasible, safe and avoid the complications of an abdominal incision.

Setorectomia posterior direita laparoscópica no tratamento dos tumores hepáticos

INTRODUÇÃO: A ressecção de neoplasias no setor posterior direito costuma ser um desafio técnico pela dificuldade de sua abordagem. Adicionalmente, as hepatectomias laparoscópicas tem se tornado alternativa interessante em virtude de muitas vantagens (baixa morbidade, curto tempo de internação, retorno precoce as atividades laborais e bons resultados cosméticos). OBJETIVO: Relatar experiência em doentes submetidos à setorectomia posterior direita laparoscópica por uma única equipe. MÉTODOS: Cinco doentes foram operados entre novembro de 2008 a agosto de 2010. A idade variou de 21 a 63 anos com mediana de 43 anos. Foram quatro mulheres e um homem. A causa das neoplasias foi: adenoma (n=2), hepatocarcinoma (n=1) e metástases (n=2). A lesão foi solitária em três casos (60 %). A média do tamanho das lesões foi 3,3 cm (1,8-5). Foram analisados: tempo cirúrgico, sangramento operatório, morbimortalidade, tempo de internação e tempo de retorno à atividade habitual. RESULTADOS: A média de tempo cirúrgico foi de 160 minutos (90-260). A de sangramento intra-operatório foi de 200 ml (0-500). Nenhum doente foi transfundido. Não houve mortalidade e a morbidade foi nula. A mediana de internação foi de três dias (2-5). A mediana de retorno às atividades cotidianas foi de 12 dias (7-20). A mediana de seguimento foi de 13 meses (1-20). Não houve recidiva de lesão. CONCLUSÃO: A setorectomia posterior direita laparoscópica representa boa opção tática para o tratamento dos tumores hepáticos situados no setor posterior do lobo direito. É opção segura que evita grandes incisões com morbimortalidade. Também apresenta bom resultado cosmético e retorno precoce ao trabalho.
