A case of pancreaticoduodenectomy and partial hepatic resection as repeat cytoreductive surgery for recurrent pseudomyxoma peritonei

Background For recurrent pseudomyxoma peritonei (PMP), repeat cytoreductive surgery (CRS) with or without hyperthermic intraperitoneal chemotherapy (HIPEC) can provide survival benefits if patients are carefully selected. We describe a case of pancreaticoduodenectomy and partial liver resection (HPD) as the repeat CRS for a recurrent tumor that infiltrated the pancreatic head around the hepatic hilum. This is the first report of HPD for recurrent PMP. Case presentation The patient was a 58-year-old male without comorbidities. In 2001, he was diagnosed with PMP at the time of laparoscopic cholecystectomy. In 2004, CRS, including total peritoneal resection, pyloric gastrectomy, splenectomy, and right hemicolectomy with HIPEC was performed (peritoneal cancer index (PCI) = 28). In 2008, the first repeat CRS with HIPEC was performed (PCI = 14). In 2016, fourth repeat CRS, including partial hepatectomy with HIPEC for recurrence of the round ligament of the liver, was performed. In 2017, a tumor of 5 cm in size was observed from the hepatic hilum to the pancreatic head, which infiltrated the main pancreatic duct. Other tumors 2 cm in size were observed (PCI = 7). We performed the fifth repeat CRS, including HPD. The adhesions of the small intestine from around the liver to the lower abdomen were detached for the reconstruction of pancreatojejunostomy and cholangiojejunostomy. The uncinate approach was applied for the pancreatic head resection because it was difficult to identify the cranial part of the pancreas due to adhesions in the hepatoduodenal ligament and the omental bursa. We approached to the origin of the extrahepatic Glissonean pedicle by resecting a part of the liver around the hepatic hilum using transhepatic hilar approach. A complete cytoreduction was achieved. The postoperative pathological diagnosis was a recurrence of PMP, which is equivalent to peritoneal mucinous carcinomatosis. He was discharged on the 22nd postoperative day without major postoperative complications. The patient survived without recurrence four years after HPD. Conclusions Even for recurrence around the hepatic hilum and the pancreatic head, repeat CRS can be safely performed by applying the techniques of hepatobiliary pancreatic surgery.

1 Laparoskopische posterolaterale Sektionektomie beim hepatozellulären Karzinom – Erhöhung der onkologischen Präzision durch Kombination des Glissonean Pedicle Approach und der Fluoreszenznavigation

Zusammenfassung Zielsetzung Minimalinvasive Eingriffe im Bereich der Leberchirurgie werden aufgrund des intraoperativ geringeren Blutverlustes, der verringerten postoperativen Morbidität sowie der verkürzten Aufenthaltsdauer im Vergleich zur offenen Leberchirurgie immer häufiger durchgeführt. Bei primären Lebertumoren erscheinen exakte Resektionsränder als vorteilhaft, stellen allerdings eine Herausforderung in der minimalinvasiven Technik dar. In diesem Fallbericht zielten wir darauf ab, die chirurgische Präzision durch Kombination des Glissonean Pedicle Approach mit intraoperativer Fluoreszenzfärbung zu erhöhen. Indikation Eine 73-jährige Patientin mit einer CHILD-A-Leberzirrhose durch eine chronische Hepatitis-C-Infektion wurde mit erhöhten Werten des Tumormarkers Alphafetoprotein (792 ng/ml) unserer Klinik vorgestellt. Die Verdachtsdiagnose eines einzelnen hepatozellulären Karzinoms (HCC) mit einer Größe von 2,2 cm in den Segmenten 6/7 wurde mittels Schnittbildgebung bestätigt. Entsprechend der Empfehlung des Tumorboards wurde eine anatomische posterolaterale Resektion entsprechend dem Glissonean Pedicle Approach geplant. Methode Die Patientin wurde in französischer Position gelagert. Nach der Mobilisierung der rechten Leber wurde der posterolaterale Pedikel identifiziert und ligiert. Anschließend wurde Indocyaningrün (ICG) in einer Dosierung von 0,2 mg/kg Körpergewicht intravenös injiziert. Das perfundierte Parenchym der Segmente I–V und VIII färbte sich grün, während die nicht perfundierten posterolateralen Segmente VI und VII ungefärbt blieben. Die Transsektionslinie wurde unter ICG-Bildgebung markiert und zeigte den Übergang des posterolateralen zum anteromedialen Sektor an. Die Dissektion des Parenchyms wurde unter intermittierender ICG-gesteuerter Bildgebung durchgeführt. Die histopathologische Untersuchung des Resektats bestätigte eine R0-Resektion eines gut differenzierten HCC in einer zirrhotischen Leber (Grad 4). Die Patientin konnte am 6. postoperativen Tag nach unkompliziertem Verlauf aus dem Krankenhaus entlassen werden und war in der Verlaufskontrolle nach 6 Monaten nachweislich tumorfrei. Schlussfolgerung Als zusätzliches intraoperatives Hilfsmittel ermöglicht die ICG-Bildgebung die Visualisierung von Segment- und Sektorgrenzen und erlaubt damit eine präzise anatomische Resektion. Weitere prospektive Studien sind nötig, um den Mehrwert dieser Technik zu evaluieren, insbesondere im Hinblick auf die Rate der R0-Resektionen.

Hepatectomy using a combination of extrafascial extrahepatic (Takasaki approach) and extrafascial intrahepatic pedicle approaches (Ton That Tung approach)

Selective pedicle control and anatomical liver resection are considered standard techniques in hepatectomy for hepatocellular carcinoma. In 1963, Ton That Tung made significant improvements in hepatectomy techniques with the principle of locating and ligation of Glissonean pedicle in the liver parenchyma based on precise knowledge of vascular and biliary anatomy (Tung TT, Quang ND. A new technique for operating on the liver. Lancet 1963;281:192–3). In 1986, the extrafascial Glissonean dissection was first introduced by Takasaki in 1986. This is a simple and safe technique that helps to identify the exact borders between liver sections for anatomic liver resection (Takasaki K. Glissonean pedicle transection method for hepatic resection: a new concept of liver segmentation. J Hepatobiliary Pancreat Surg 1998;5:286–91). The combination of two techniques helps minimize complications, reduce ischemic time of future liver remnant, intraoperative blood loss and avoid migration of cancer cells into other segments.

Isolated Caudate Lobectomy: Glissonean Pedicle Transection Method, and Combined Right–left Side Approach. A Case Series Report

Tumors located in caudate lobe may be primary tumors, or metastases from other sites. Isolated caudate lobectomy (ICL) is a challenging procedure due to its complex structure and location. The access route to caudatelobe has an important role in the success of the operation. A combined right and left side approach is recommended for benign or suspected malignant tumor located anterior to the vena cava or entirely in the caudate lobe, which radical resection of the caudate is necessary. We report two cases of successfully with Glissonean pedicle transection method described by Takasaki and combined right and left side approach. We found this to be a safe and effective approach, which can be applied to all case of benign tumors; or in the case of malignant tumors located entirely in the caudate lobe when extended hepatic resection is not possible due to poor liver function. or small remnant liver volume.

Feasibility of Microwave-Based Scissors and Tweezers in Partial Hepatectomy: An Initial Assessment on Canine Model

Purpose: This study aimed to assess the feasibility of partial hepatectomy (PH) simplified by using microwave-based devices in animal experiments.Methods: PH was performed on 16 beagles using either Acrosurg Scissors (AS) or Acrosurg Tweezers (AT) without hepatic pedicle (HP) control. Parenchymal transection time, Glissonean pedicle (GP) seal time, bleeding volume, bile leak, and burst pressure were recorded. Probable complications were investigated after 4 weeks.Results: Transection time (6.5 [6.0–7.6] vs. 11.8 [10.5–20.2] min, p < 0.001) with AT were significantly shorter than with AS. GP sealing times (60 [55–60] vs. 57 [46–91] s, p = 0.859) by both devices were nearly similar. Bleeding volume in the AT group was approximately one-fourth of that in the AS group (6.7 [1.4–22] vs. 28.8 [5.8–48] mL, p = 0.247). AT created higher burst pressure on the bile duct stumps (p = 0.0161). The two devices did not differ significantly in morbidity and mortality after four-week follow-up.Conclusion: Acrosurg devices achieved a safe PH without HP control owing to microwave-based sealing. AS could be used alone in PH, whereas the clamp-crushing function of AT seemed more advantageous in reducing the transection time and blood loss.
