- Hand-assisted Approach as a Model to Teach Complex Laparoscopic Hepatectomies: Preliminary Results(2017) MAKDISSI, Fabio F.; JEISMANN, Vagner B.; KRUGER, Jaime A. P.; COELHO, Fabricio F.; RIBEIRO-JUNIOR, Ulysses; CECCONELLO, Ivan; HERMAN, PauloBackground: Currently, there are limited and scarce models to teach complex liver resections by laparoscopy. The aim of this study is to present a hand-assisted technique to teach complex laparoscopic hepatectomies for fellows in liver surgery. Materials and Methods: Laparoscopic hand-assisted approach for resections of liver lesions located in posterosuperior segments (7, 6/7, 7/8, 8) was performed by the trainees with guidance and intermittent intervention of a senior surgeon. Data as: (1) percentage of time that the senior surgeon takes the surgery as main surgeon, (2) need for the senior surgeon to finish the procedure, (3) necessity of conversion, (4) bleeding with hemodynamic instability, (5) need for transfusion, (6) oncological surgical margins, were evaluated. Results: In total, 12 cases of complex laparoscopic liver resections were performed by the trainee. All cases included deep lesions situated on liver segments 7 or 8. The senior surgeon intervention occurred in a mean of 20% of the total surgical time (range, 0% to 50%). A senior intervention > 20% was necessary in 2 cases. There was no need for conversion or reoperation. Neither major bleeding nor complications resulted from the teaching program. All surgical margins were clear. Conclusions: This preliminary report shows that hand-assistance is a safe way to teach complex liver resections without compromising patient safety or oncological results. More cases are still necessary to draw definitive conclusions about this teaching method.
- Are Hybrid Liver Resections Truly Minimally Invasive? A Propensity Score Matching Analysis(2017) COELHO, Fabricio Ferreira; KRUGER, Jaime Arthur Pirola; JEISMANN, Vagner Birk; FONSECA, Gilton Marques; MAKDISSI, Fabio Ferrari; FERREIRA, Leandro Augusto; D'ALBUQUERQUE, Luiz Augusto Carneiro; CECCONELLO, Ivan; HERMAN, PauloBackground: Hybrid liver resection is considered a modality of minimally invasive surgery; however, there are doubts regarding loss of benefits of laparoscopy due to the use of an auxiliary incision. We compared perioperative results of patients undergoing hybridxopen and hybridxpure laparoscopic resections. Methods: Consecutive patients undergoing liver resection between June 2008 and January 2016 were studied. Study groups were compared after propensity score matching (PSM). Results: Six hundred forty-four resections were included in the comparative analysis: 470 open, 120 pure laparoscopic, and 54 hybrids. After PSM, 54 patients were included in each group. Hybridxopen: hybrid technique had shorter operative time (319.5108.6x376.2 +/- 155.8 minutes, P=.033), shorter hospital stay (6.0 +/- 2.7x8.1 +/- 5.6 days, P=.001), and lower morbidity (18.5%x40.7%, P=.003). Hybridxpure laparoscopic: hybrid group had lower conversion rate (0%x13%, P=.013). There was no difference regarding estimated blood loss, transfusion rate, hospital stay, complications, or mortality. Conclusions: Hybrid resection has better perioperative results than the open approach and is similar to pure laparoscopy. The hybrid technique should be considered a minimally invasive approach.
- Video assisted resections. Increasing access to minimally invasive liver surgery?(2015) COELHO, Fabricio Ferreira; PERINI, Marcos Vinícius; KRUGER, Jaime Arthur Pirola; LUPINACCI, Renato Micelli; MAKDISSI, Fábio Ferrari; D'ALBUQUERQUE, Luiz Augusto Carneiro; CECCONELLO, Ivan; HERMAN, PauloObjective: 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.
