- Enucleation of liver tumors: you do not have to feel blue about it(2015) SURJAN, Rodrigo C.; MAKDISSI, Fabio F.; BASSERES, Tiago; MACHADO, Marcel A. C.Enucleation of hepatic tumors is a low-morbidity technique with adequate oncological results that is useful in many clinical settings. Compared with anatomical liver resections, it offers the advantage of maximal hepatic parenchymal preservation. However, some technical adversities may occur during the enucleation of liver tumors, such as difficulty in finding the lesions by intraoperative ultrasonography after hepatic transection or further visually spotting the tumor within the parenchyma if a first specimen is retracted not containing the lesion. We describe an innovative technique that overcomes these possible adversities and makes the enucleation of liver tumors easier and more precise.
- Totally Laparoscopic Hepatic Bisegmentectomy (s4b+s5) and Hilar Lymphadenectomy for Incidental Gallbladder Cancer(2015) MACHADO, Marcel Autran; MAKDISSI, Fabio F.; SURJAN, Rodrigo C.Background. Gallbladder cancer is suspected preoperatively in only 30 % of all patients, while the remaining 70 % of cases are discovered incidentally by the pathologist. The increasing rate of cholecystectomies via laparoscopy has led to the detection of more gallbladder cancers in an early stage, and extended resection with regional lymph node dissection has been suggested. We present a video of a totally laparoscopic liver resection (segments 5 and 4b) with regional lymphadenectomy in a patient with an incidental gallbladder cancer. Methods. A 50-year-old woman underwent laparoscopic cholecystectomy, and pathology revealed a T1b gallbladder carcinoma. The patient was referred for further treatment. Contact with the primary surgeon revealed that no intraoperative cholangiogram was performed, and the gallbladder was removed intact, with no perforation, and inside a plastic retrieval bag. Pathology revision confirmed T1b, and positron emission tomography/computed tomography was negative. The multidisciplinary tumor board recommended radical re-resection, and a decision was made to perform a laparoscopic extended hilar lymphadenectomy, along the resection of segments 5 and 4b. Results. Operative time was 5 h, with an estimated blood loss of 240 mL. Recovery was uneventful and the patient was discharged on the fourth postoperative day. Final pathology showed no residual disease and no lymph node metastasis. Conclusions. Laparoscopic resection of liver segments 5 and 4b combined with a locoregional lymphadenectomy of the hepatoduodenal ligament is an oncologically appropriate technique, provided it is performed in a specialized center with experience in hepatobiliary surgery and advanced laparoscopic surgery. This video may help oncological surgeons to perform this complex procedure.
- Anatomical basis for the intrahepatic glissonian approach during hepatectomies(2015) SURJAN, Rodrigo Cañada Trofo; MAKDISSI, Fábio Ferrari; MACHADO, Marcel Autran CesarBACKGROUND: Anatomical liver resections are based on some basic technical principles such as vascular control, ischemic area delineation to be resected and maximum parenchymal preservation. These aspects are achieved by the intrahepatic glissonian approach, which consists in accessing the pedicles of hepatic segments within the hepatic parenchyma. Small incisions on well-defined anatomical landmarks are performed to approach the pedicles, making dissection of the hilar plate unnecessary. AIM: Analyze parameters in liver anatomy related to intrahepatic surgical technique to glissonians pedicles, to set the normal anatomy related to the procedure and thereby facilitate the attainment of this technique. METHODS: Anatomical parameters related to the intrahepatic glissonian approach were studied in 37 cadavers. Measurements were performed with precision instruments. Data were expressed as mean±standard deviation. The subjects were divided into groups according to gender and liver weight and groups were compared statistically. RESULTS: Twenty-five cadavers were male and 12 female. No statistically significant difference was observed in virtually all parameters when groups were compared. This demonstrates the consistency of the anatomical parameters related to the intrahepatic glissonian approach. CONCLUSION: The results obtained in this study made possible major technical advances in the realization of open and laparoscopic hepatectomies with intrahepatic glissonian approach, and can help surgeons to perform liver resections by this method.
- 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.
- Innovative technique for gastric retraction during laparoscopic distal pancreatectomy: the marionette(2015) SURJAN, Rodrigo C.; BASSERES, Tiago; MAKDISSI, Fabio F.; MACHADO, Marcel A. C.Laparoscopic distal pancreatectomies became more common in the past few years as a safe and effective treatment option for benign and low-grade malignant tumors of the body and tail of the pancreas. Adequate exposure and wide operative field are crucial to perform this procedure, and this is achieved by retraction of the stomach with an angled liver retractor or a grasper through a subxiphoid trocar, that is usually used only to this purpose. We developed an innovative technique to retract the stomach during laparoscopic distal pancreatectomies that provides excellent operative field and frees the subxiphoid trocar to be used in other tasks during the surgery.
