Laparoscopic Resection of Hilar Cholangiocarcinoma

Background: Surgical resection is the only curative treatment for hilar cholangiocarcinoma. Laparoscopic hepatectomy has been used to treat several types of liver neoplasms. However, technical issues have limited the adoption of laparoscopy for the treatment of hilar cholangiocarcinoma. To date there is only one report of minimally invasive procedure for hilar cholangiocarcinoma in the literature. The present video-assisted procedure shows a laparoscopic resection of hilar cholangiocarcinoma. Patient and Methods: A 43-year-old woman with progressive jaundice due to left-sided hilar cholangiocarcinoma was referred for treatment. The decision was to perform a laparoscopic left hepatectomy with lymphadenectomy and resection of extrahepatic bile ducts. Biliary reconstruction was performed using the hybrid method. Results: Operative time was 300 minutes with minimum blood loss and no need for blood transfusion. Recovery was uneventful, and the patient was discharged on postoperative Day 7. Pathology revealed a well-differentiated cholangiocarcinoma with negative lymph nodes and clear surgical margins. The patient is well with no signs of the disease 18 months after the procedure. Conclusions: Laparoscopic left hepatectomy with lymphadenectomy is safe and feasible in selected patients and when performed by surgeons with expertise in liver surgery and minimally invasive techniques. The use of a hybrid method may be needed for biliary reconstruction, especially in cases where position and size of remnant bile ducts may jeopardize the anastomosis. Further studies are still needed to confirm the benefit of this approach over conventional surgery for hilar cholangiocarcinoma

ALPPS Procedure with the Use of Pneumoperitoneum

ABSTRACT Background. A new method for liver hypertrophy was recently introduced, the so-called associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) procedure. We present a video of an ALPPS procedure with the use of pneumoperitoneum. Methods. A 29-year-old woman with colon cancer and synchronous liver metastasis underwent a two-stage liver resection by the ALPPS technique because of an extremely small future liver remnant. Results. The first operation began with 30 min pneumoperitoneum. Anatomical resection of segment 2 was performed, followed by multiple enucleations on the left liver. The right portal vein was ligated and the liver partitioned. The abdominal cavity was partially closed, and a 10 mm trocar was left to create a pneumoperitoneum for additional 30 min. The patient had an adequate future liver remnant volume after 7 days, but she was not clinically fit for the second stage of therapy, so it was postponed. She was discharged on day 7 after surgery. The second stage took place 3 weeks later and consisted of an en-bloc right trisectionectomy extended to segment 1. The patient recovered and was discharged 9 days after second-stage surgery. Postoperative CT scan revealed an enlarged remnant liver. Conclusions. The ALPPS procedure is a new revolutionary technique that permits R0 resection even in patients with massive liver metastasis. The use of pneumoperitoneum during the first stage is an easy tool that may prevent hard adhesions, allowing an easier second stage. This video may help oncological surgeons to perform and standardize this challenging procedure. Surgical resection is the only curative modality of treatment in patients with colorectal liver metastases. Although multiple and bilobar metastases are correlated with the worst prognosis, this condition should not be considered a contraindication to hepatic resection, because even in this situation, surgery is still the only curative treatment. 1-3 The most common strategy for these patients is to perform neoadjuvant therapy followed by two-stage hepatectomy with minor resections on the left lateral liver (future liver remnant, FLR) combined with right portal vein occlusion as the first stage, followed by right trisectionectomy. 2 However, insufficient FLR volume may preclude liver resection even after portal vein occlusion. To overcome this problem, a new method to increase liver hypertrophy before extended hepatectomy was recently described by a German multicenter study and validated by the group of de Santibañes and Clavien

Guidelines for the management of neuroendocrine tumours by the Brazilian gastrointestinal tumour group

Neuroendocrine tumours are a heterogeneous group of diseases with a significant variety of diagnostic tests and treatment modalities. Guidelines were developed by North American and European groups to recommend their best management. However, local particularities and relativisms found worldwide led us to create Brazilian guidelines. Our consensus considered the best feasible strategies in an environment involving more limited resources. We believe that our recommendations may be extended to other countries with similar economic standards.Univ Sao Paulo, Inst Canc Estado Sao Paulo, BR-01246000 Sao Paulo, BrazilUniv Sao Paulo, Fac Med, Dept Radiol & Oncol, BR-01246903 Sao Paulo, BrazilHosp Sirio Libanes, BR-01308050 Sao Paulo, BrazilHosp Moinhos de Vento Porto Alegre, BR-90035000 Porto Alegre, RS, BrazilOncoctr, BR-30360680 Belo Horizonte, MG, BrazilUniv Fed Rio Grande do Sul, Dept Cirurgia, BR-90040060 Porto Alegre, RS, BrazilHosp Clin Porto Alegre, BR-90035903 Porto Alegre, RS, BrazilUniv Fed Ceara, Fac Med, Dept Fisiol & Farmacol, BR-60020180 Fortaleza, Ceara, BrazilHosp Univ Walter Cantidio, BR-60430370 Fortaleza, Ceara, BrazilInst Nacl Canc, BR-20230240 Rio De Janeiro, BrazilUniv Sao Paulo, Fac Med, Disciplina Endocrinol & Metabol, BR-01246903 Sao Paulo, BrazilAC Camargo Canc Ctr, Dept Surg, BR-01509010 Sao Paulo, BrazilUniv Sao Paulo, Fac Med, Dept Gastroenterol, Sao Paulo, BrazilUniv Fed Ciencias Saude Porto Alegre, BR-90050170 Porto Alegre, RS, BrazilHosp Albert Einstein, BR-05652900 Sao Paulo, BrazilHosp Base, Fac Med Sao Jose do Rio Preto, BR-15090000 Sao Paulo, BrazilSanta Casa Sao Jose do Rio Preto, BR-15025500 Sao Jose Do Rio Preto, BrazilPontificia Univ Catolica Parana, Hosp Erasto Gaertner, BR-81520060 Curitiba, Parana, BrazilUniv Fed Rio Grande do Norte, BR-59300000 Natal, RN, BrazilUniv Sao Paulo, Inst Coracao, BR-05403900 Sao Paulo, BrazilAC Camargo Canc Ctr, Med Oncol, BR-01509010 Sao Paulo, BrazilUniv Fed Sao Paulo, Disciplina Gastroenterol, BR-04021001 Sao Paulo, BrazilHosp Sao Rafael, BR-41253190 Salvador, BA, BrazilHosp Canc Barretos, Dept Cirurgia Aparelho Digest Alto & Hepatobiliop, BR-14784400 Sao Paulo, BrazilUniv Sao Paulo, Fac Med, Dept Patol, BR-01246903 Sao Paulo, BrazilClin AMO, BR-1950640 Salvador, BA, BrazilHosp Sao Jose, BR-01323001 Sao Paulo, BrazilUniv Nove de Julho, BR-02111030 Sao Paulo, BrazilUniv Fed Sao Paulo, Disciplina Gastroenterol, BR-04021001 Sao Paulo, BrazilWeb of Scienc

Laparoscopic Enucleation of Liver Tumors. Corkscrew Technique Revisited

Background: Enucleation of small lesions located near the hepatic surface can be achieved with low morbidity and mortality. This article describes a simple laparoscopic technique for enucleation of liver tumors. Methods: After inspection and intraoperative ultrasonography, Glisson`s capsule is marked with eletrocautery 2 cm away from the tumor margin. Ultrasonography is used to ascertain surgical margin right before liver transection. Hemihepatic ischemia is applied and marked area is anchored by stitches. The suture is held together by metallic clips and upward traction is performed, facilitating the transection of the parenchyma and correct identification of vascular and biliary structures. Results: This technique has been successfully employed in six consecutive patients. There were four men and two women, mean age 50.3 years. Four patients underwent liver resection for malignant disease and two for benign liver neoplasm. Pathologic surgical margins were free in all cases and mean hospital stay was 2 days. No postoperative mortality was observed. Conclusion: This technique may facilitate laparoscopic nonanatomical liver resection and reduce risk of positive surgical margins. It is also useful in combination with anatomical laparoscopic liver resections such as right or left hemihepatectomies in patients with bilateral liver tumors as occurred in one of our patients

Intrahepatic Glissonian Approach for Pure Laparoscopic Left Hemihepatectomy

Background: Recent advances in laparoscopic devices and experience with advanced techniques have increased the indications for laparoscopic liver. Aim: The aim of this work was to present a video with technical aspects of a pure laparoscopic left hemi-hepatectomy (segments 2, 3, and 4) by using the intrahepatic Glissonian approach and control of venous outflow without hilar dissection or the Pringle maneuver. Patient and Method: A 63-year-old woman with a 5-cm solitary liver metastasis was referred for treatment. Four trocars were used. The left lobe was pulled upward and the lesser omentum was divided, exposing Arantius' ligament. This ligament is a useful landmark for the identification of the main left Glissonian pedicle. A small anterior incision was made in front of the hilum, and a large clamp was introduced behind the Arantius' ligament toward the anterior incision, allowing control of the left main sheath. Ischemic discoloration of the left liver was achieved and marked with cautery. The vascular clamp was replaced by a stapler. If ischemic delineation was coincident with a previously marked area, the stapler was fired. The left hepatic vein was dissected and encircled. Parenchymal transection and vascular control of the hepatic veins were accomplished with a Harmonic scalpel and an endoscopic stapling device, as appropriate. All these steps were performed without the Pringle maneuver and without hand assistance. Results: Operative time was 220 minutes with minimum blood loss. Hospital stay was 4 days. Pathology showed free surgical margins. The patient is alive with no signs of recurrence 18 months after the operation. Conclusion: Totally laparoscopic left hemihepatectomy is safe and feasible in selected patients and should be considered for patients with benign or malignant liver neoplasms. The described technique, with the use of the intrahepatic Glissonian approach and control of venous outflow, may facilitate laparoscopic left hemihepatectomy by reducing the technical difficulties in pedicle control and may decrease bleeding during liver transection

A Simple Technique for Large Tumor Removal During Laparoscopic Liver Resection

Experience with laparoscopic liver resections has increased in recent years, and so have the number of patients operated on by minimally invasive techniques. Specimen extraction is an important step of laparoscopic liver resection. The size of the specimen, is Usually a limitation for the use Of laparoscopy. The aim of this paper is to describe a new technique combining Pfannenstiel suprapubic incision and obstetric forceps to remove a large specimen from laparoscopic liver resections. The present technique allows an expeditious extraction of intact specimens, even huge ones, through a standard suprapubic Pfannenstiel incision. This technique has additional functional and cosmetic advantages over other techniques of specimen retrieval. We believe that the described technique is feasible, can be easily and rapidly performed, and facilitates laparoscopic liver resection by reducing the technical difficulties for specimen removal and may also be used in other abdominal laparoscopic interventions that deal with large surgical specimens
