- Laparoscopic Pancreatoduodenectomy in 50 Consecutive Patients with No Mortality: A Single-Center Experience(2016) MACHADO, Marcel Autran C.; SURJAN, Rodrigo C.; BASSERES, Tiago; SILVA, Izabella B.; MAKDISSI, Fabio F.Background: Laparoscopic pancreatic surgery has gradually expanded to include pancreatoduodenectomy (PD). This study presents data regarding the efficacy of laparoscopic PD in a single center. Methods: This was a single-cohort, prospective observational study. From March 2012 to September 2015, 50 consecutive patients underwent laparoscopic PD using a five-trocar technique. Reconstruction of the digestive tract was performed with double jejunal loop technique whenever feasible. Patients with radiological signs of portal vein invasion were operated by open approach. Results: Twenty-seven women and 23 men with a median age of 63 years (range 23-76) underwent laparoscopic PD. Five patients underwent total pancreatectomy. All, but 1 patient (previous bariatric operation), underwent pylorus-preserving resection. Reconstruction was performed with double jejunal loop in all cases except in 5 cases of total pancreatectomy. Conversion was required in 3 patients (6%) as a result of difficult dissection (two cases) and unsuspected portal vein invasion (1 patient). Median operative time was 420 minutes (range 360-660), and the 90-day mortality was nil. Pancreatic fistula occurred in 13 patients (26%). There was one grade C (reoperated), one grade B (percutaneous drainage), and all remaining were grade A (conservative treatment). Other complications included port site bleeding (n = 1), biliary fistula (n = 2), and delayed gastric emptying (n = 2). Mean hospital stay was 8.4 days (range 5-31). Conclusions: Laparoscopic PD is feasible and safe, but is technically demanding and may be reserved to highly skilled laparoscopic surgeons with proper training in high-volume centers. Isolated pancreatic anastomosis may be useful to decrease the severity of postoperative pancreatic fistulas. Therefore, it could be a good option in patients with a high risk for developing postoperative pancreatic, as well as by less-experienced 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 BellorioSurgical 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.
article 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.- Laparoscopic pylorus-preserving pancreatoduodenectomy.

- First totally laparoscopic ALPPS procedure with selective hepatic artery clamping Case report of a new technique(2016) SURJAN, Rodrigo C.; MAKDISSI, Fabio F.; BASSERES, Tiago; LEITE, Denise; CHARLES, Luiz F.; BEZERRA, Regis O.; SCHADDE, Erik; MACHADO, Marcel AutranBackground: ALPPS (Associating Liver Partition and Portal vein ligation for Staged hepatectomy) is a new surgical approach for the treatment of liver tumors. It is indicated in cases where the future liver remnant is not sufficient to maintain postoperative liver function. We report a totally laparoscopic ALPPS with selective hepatic artery clamping. Pneumoperitoneum itself results in up to 53% of portal vein flow and selective hepatic artery clamping can reduce blood loss while maintaining hepatocellular function. Therefore, the combination of both techniques may result in effective control of bleeding with no damage in the liver function that may have direct impact in the result of ALPPS procedure. Methods: A 65-year-old man with colorectal liver metastases in all liver segments, except liver segment 1 (S1), were evaluated as unresectable. He underwent chemotherapy with objective response and multidisciplinary board decided for ALPPS procedure. First stage was performed entirely by laparoscopy and consisted of enucleation of metastases from segments 2 and 3, ligation of the right portal vein and liver splitting under selective common hepatic artery clamping. The second stage was done 3 weeks later and consisted of laparoscopic right trisectionectomy by laparoscopy. Results: Operative time was 250 and 200minutes, respectively. Estimated blood loss was 150 and 100mL. There was no need for transfusion or hospitalization in intensive care. He was discharged on the 3rd and 5th postoperative day, respectively. Recovery was uneventful after both stages and patient did not present any sign of liver failure. Elevation of liver enzymes was minimal. Computerized tomography (CT) scan before second stage showed a liver hypertrophy of 53%, sFLR was 0.37 before second stage, or 33% of the total liver volume. CT scan shows no residual liver disease and optimum liver regeneration. Patient is well with no evidence of the disease 11 months after the procedure. Conclusions: Totally laparoscopic ALPPS is a feasible and safe approach for selected patients with liver tumors. The hypertrophy of the remaining liver was adequate and sequential procedures were performed without morbidity and no mortality. Selective hepatic artery clamping seems to be an interesting solution to decrease intraoperative blood loss without the harsh effect of Pringle maneuver.
