    Laparoscopic Pylorus-Preserving Pancreatoduodenectomy with Double Jejunal Loop Reconstruction: An Old Trick for a New Dog
    (2013) MACHADO, Marcel Autran C.; MAKDISSI, Fabio F.; SURJAN, Rodrigo C. T.; MACHADO, Marcel C. C.
    Background: Pancreatoduodenectomy is an established procedure for the treatment of benign and malignant diseases located at the pancreatic head and periampullary region. In order to decrease morbidity and mortality, we devised a unique technique using two different jejunal loops to avoid activation of pancreatic juice by biliary secretion and therefore reduce the severity of pancreatic fistula. This technique has been used for open pancreatoduodenectomy worldwide but to date has never been described for laparoscopic pancreatoduodenectomy. This article reports the technique of laparoscopic pylorus-preserving pancreatoduodenectomy with two jejunal loops for reconstruction of the alimentary tract. Materials and Methods: After pancreatic head resection, retrocolic end-to-side pancreaticojejunostomy with duct-to-mucosa anastomosis is performed. The jejunal loop is divided with a stapler, and side-to-side jejunojejunostomy is performed with the stapler, leaving a 40-cm jejunal loop for retrocolic hepaticojejunostomy. Finally, end-to-side duodenojejunostomy is performed in an antecolic fashion. Results: This technique has been successfully used in 3 consecutive patients with pancreatic head tumors: 2 patients underwent hand-assisted laparoscopic pylorus-preserving pancreatoduodenectomy, and 1 patient underwent totally laparoscopic pylorus-preserving pancreatoduodenectomy. One patient presented a Grade A pancreatic fistula that was managed conservatively. One patient received blood transfusion. Mean operative time was 9 hours. Mean hospital stay was 7 days. No postoperative mortality was observed. Conclusions: Laparoscopic pylorus-preserving pancreatoduodenectomy with double jejunal loop reconstruction is feasible and may be useful to decrease morbidity and mortality after pancreatoduodenectomy. This operation is challenging and may be reserved for highly skilled laparoscopic surgeons.

    A novel technique for hepatic vein reconstruction during hepatectomy
    (2016) SURJAN, Rodrigo C.; BASSERES, Tiago; PAJECKI, Denis; PUZZO, Daniel B.; MAKDISSI, Fabio F.; MACHADO, Marcel A. C.; BATTILANA, Alexandre Gustavo Bellorio
    Surgical resection is the treatment of choice for malignant liver tumours. Nevertheless, surgical approach to tumours located close to the confluence of the hepatic veins is a challenging issue. Trisectionectomies are considered the first curative option for treatment of these tumours. However, those procedures are associated with high morbidity and mortality rates primarily due to post-operative liver failure. Thus, maximal preservation of functional liver parenchyma should always be attempted. We describe the isolated resection of Segment 8 for the treatment of a tumour involving the right hepatic vein and in contact with the middle hepatic vein and retrohepatic vena cava with immediate reconstruction of the right hepatic vein with a vascular graft. This is the first time this type of reconstruction was performed, and it allowed to preserve all but one of the hepatic segments with normal venous outflow. This innovative technique is a fast and safe method to reconstruct hepatic veins.

    Right Trisectionectomy with Principle En Bloc Portal Vein Resection for Right-Sided Hilar Cholangiocarcinoma: No-Touch Technique
    (2012) MACHADO, Marcel Autran; MAKDISSI, Fabio F.; SURJAN, Rodrigo C.
    Background. The most favorable long-term survival rate for hilar cholangiocarcinoma is achieved by a R0 resection. A surgical concept involving a no-touch technique, with extended right hepatic resections and principle en bloc portal vein resection was described by Neuhaus et al.(1) According to Neuhaus et al.,(1) their technique may increase the chance of R0, because the right branch of the portal vein and hepatic artery is in close contact with the tumor and is frequently infiltrated. The left artery runs on the left margin of the hilum and often is free. The 5-year survival rate for their patients is 61% but 60-day mortality rate is 8%.(1,2) Given the increased morbidity, some authors do not agree with routine resection of portal vein and may perform the resection of portal vein only on demand, after intraoperative assessment and confirmation of portal vein invasion.(3) This video shows en bloc resection of extrahepatic bile ducts, portal vein bifurcation, and right hepatic artery, together with extended right trisectionectomy (removal of segments 1, 4, 5, 6, 7, and 8). Methods. A 75-year-old man with progressive jaundice due to right-sided hilar cholangiocarcinoma underwent percutaneous biliary drainage with metallic stents for palliation. The patient was referred for a second opinion. Serum bilirubin levels were normal, and CT scan showed a resectable tumor, but volumetry showed a small left liver remnant. Right portal vein embolization was then performed, and CT scan performed after 4 weeks showed adequate compensatory hypertrophy of the future liver remnant (segments 2 and 3). Surgical decision was to perform a right trisectionectomy with en bloc portal vein and bile duct resection using the no-touch technique. Results. The operation began with hilar lymphadenectomy. The common bile duct is sectioned. Right hepatic artery is ligated. Left hepatic artery is encircled. Portal vein is dissected and encircled. Right liver is mobilized and detached from retrohepatic vena cava. Right and middle hepatic veins are divided. A right trisectionectomy along with segment 1 is performed, leaving specimen attached only by the portal vein. Portal vein is severed above and below the tumor, and specimen is removed. Portal vein anastomosis is done end-to-end with 6-0 Prolene. Doppler confirms normal portal flow. The procedure ends with Roux-Y hepaticojejunostomy. The patient recovered uneventfully, without transfusion, and was discharged on the tenth postoperative day. Final pathology confirmed hilar cholangiocarcinoma and R0 resection. Portal vein showed microscopic invasion. Patient is well with no evidence of the disease 14 months after the procedure. Conclusions. Right trisectionectomy with en bloc portal vein and bile duct resection is feasible and may enhance chance for R0 resection and a better late outcome, especially in cases when portal vein is microscopically involved. Although described in 1999, there are few detailed descriptions of this procedure, and to the best of our knowledge, no multimedia articles are available. This video may help oncological surgeons to perform and standardize this challenging procedure.

    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.

    LAPAROSCOPIC UNCINATECTOMY: A MORE CONSERVATIVE APPROACH TO THE UNCINATE PROCESS OF THE PANCREAS
    (2017) SURJAN, Rodrigo Cañada; BASSERES, Tiago; MAKDISSI, Fabio Ferrari; MACHADO, Marcel Autran Cesar; ARDENGH, José Celso
    ABSTRACT Background: The isolate resection of the uncinate process of the pancreas is a rarely described procedure but is an adequate surgery to treat benign and low grade malignancies of the uncinate process of the pancreas. Aim: To detail laparoscopic uncinatectomy technique and present the initial results. Method: Patient is placed in supine position with the surgeon between legs. Three 5-mm, one 10-mm and one 12-mm trocars were used to perform the isolated resection of the uncinate process of the pancreas. Parenchymal transection is performed with harmonic scalpel. A hemostatic absorbable tissue is deployed over the area previously occupied by the uncinate process. A Waterman drain is placed. Result: This procedure was applied to an asymptomatic 62-year-old male with biopsy proven low grade neuroendocrine tumor of the pancreatic uncinate process. A laparoscopic pancreaticoduodenectomy was proposed. During the initial surgical evaluation, intraoperative sonography was performed and disclosed that the lesion was a few millimeters away from the Wirsung. The option was to perform a laparoscopic uncinatectomy. Postoperative period until full recovery was swift and uneventful. Conclusion: Laparoscopic uncinatectomy is a safe and efficient procedure when performed by surgical teams with large experience in minimally invasive biliopancreatic procedures.

    A New Technique for Liver Retraction During Single-Port Laparoscopic Surgery
    (2014) SURJAN, Rodrigo C. T.; MAKDISSI, Fabio F.; MACHADO, Marcel Autran C.
    Establishing a clear operative viewing field and adequate working space are essential steps for safe laparoscopic surgery. This aim of this article is to report a new technique of liver retraction during upper gastrointestinal laparoscopic surgery. This technique is fast and simple and precludes the use of special devices. It avoids the use of a subxiphoid trocar exclusive for liver retraction. This technique was designed to be used in single-port laparoscopic surgery but can be used in standard laparoscopic surgery to reduce the number of trocars. The first step is to perform division of the left triangular ligament. The fibrous appendix is identified. A window in the falciform ligament is created. The fibrous appendix is sutured to the peritoneum in the right subcostal area. The left lobe of the liver passes through the window in the falciform ligament, avoiding liver congestion. Optimum exposure of the upper gastrointestinal area is achieved. This new technique is easy and can be performed in various types of laparoscopic gastrointestinal surgeries without the need for specific skills or devices. We believe that our liver retraction technique is useful in single-port laparoscopic surgery and allows an excellent exposure of the upper gastrointestinal tract.

    Long-term survival after surgical treatment followed by adjuvant systemic therapy for primary duodenal melanoma
    (2020) SURJAN, Rodrigo Canada Trofo; SILVEIRA, Sergio do Prado; SANTOS, Elizabeth Santana dos; MEIRELLES, Luciana Rodrigues de
    Primary mucosal malignant melanomas of the gastrointestinal tract are rare tumors associated to poor prognosis. Primary duodenal involvement by pigmented lesions is even more uncommon, and only a few reports exist in the literature. We report the case of a patient with large primary duodenal melanoma that presented with upper intestinal obstruction and bleeding that was submitted to urgent pancreaticoduodenectomy followed by adjuvant systemic therapy with an oral alkylating agent (temozolomide) plus intravenous cisplatin. The patient presents no signs of recurrence 3 years after the surgery. We consider that radical surgical resection followed by systemic therapy is a safe and effective treatment strategy option for primary mucosal gastrointestinal melanomas.

    Totally Laparoscopic Right Hepatectomy with Roux-en-Y Hepaticojejunostomy for Right-Sided Intraductal Papillary Mucinous Neoplasm of the Bile Duct
    (2014) MACHADO, Marcel Autran; MAKDISSI, Fabio F.; SURJAN, Rodrigo C.
    Intraductal papillary neoplasm of the bile duct is a precursor lesion of cholangiocarcinoma. We present a video of a totally laparoscopic right hepatectomy with hilar dissection and lymphadenectomy, en-bloc resection of the extrahepatic bile duct, and Roux-en-Y hepaticojejunostomy in a patient with intraductal papillary neoplasm of the right hepatic duct. A 58-year-old woman with right upper quadrant pain was referred for evaluation. Abdominal ultrasonography revealed dilatation of intrahepatic and extrahepatic bile ducts. Magnetic resonance imaging showed a stop in the right bile duct, with dilatation of the distal bile duct. The decision was to perform a totally laparoscopic right hepatectomy with hilar lymphadenectomy and Roux-en-Y hepaticojejunostomy. The operative time was 400 min. Estimated blood loss was 400 ml, without the need for transfusions. Postoperative recovery was uneventful, and the patient was discharged on the 10th postoperative day. The abdominal drain was removed on the 14th postoperative drain with no signs of biliary leakage. Final pathology confirmed the diagnosis of intraductal papillary neoplasm without malignant transformation. Surgical margins were free. Patient is well with no evidence of the disease 14 months after the procedure. Laparoscopic right hepatectomy with hepaticojejunostomy is feasible and safe, provided it is performed in a specialized center and with staff with experience in hepatobiliary surgery and advanced laparoscopic surgery. Currently this operation is reserved for selected cases. This video can help oncologic surgeons to perform this complex procedure.

    Laparoscopic Partial Pancreatectomy in a Patient with Pancreas Trifurcation and Recurrent Acute Pancreatitis
    (2016) MACHADO, Marcel Autran; BASSERES, Tiago; SURJAN, Rodrigo C.; MAKDISSI, Fabio F.
    Introduction Embryologically the pancreas develops by the fusion of dorsal and ventral pancreatic elements. The ventral pancreatic bud gives rise to part of the head and uncinate process, while the remainder of the head, body, and tail of the pancreas develops from the dorsal pancreatic bud. Failure in this process may result in pancreatic duct variation. Several types have been described, including bifid pancreatic duct, ectopic pancreas and duplication anomaly. To our knowledge, pancreatic trifurcation has never been described so far. Aim To present a video of a laparoscopic partial pancreatectomy resection in a patient with trifurcation of pancreas and intermittent acute pancreatitis. Methods A forty-year-old woman suffering from intermittent episodes of acute pancreatitis with first onset at 2-years of age with multiple surgical interventions for abdominal abscess drainage until puberty when severity and number of episodes decreased. Three years ago, she experimented a new episode of severe acute pancreatitis with prolonged hospitalization and since then intermittent episodes. MRI revealed an anomalous pancreas with three pancreatic ducts. One of them with signs of obstruction and pancreatitis. Laparoscopic resection of the diseased pancreas was proposed. Results Operative time was 150 minutes. Blood loss was minimum. Recovery was uneventful and patient was discharged on the 4th postoperative day. Final pathology showed no signs of malignancy. Patient is well with no sign of the disease 12 months after operation. Conclusion Although anomaly of the pancreatic duct is extremely rare, this case should alert clinicians to be aware of such an anatomical variant that may alter the flow characteristics in the pancreatic ductal system resulting in an increased risk of relapsing episodes of acute pancreatitis. Our patient received the correct diagnosis only 38 years after the first episode of acute pancreatitis.
