Abstract

Resection of all tumor implants with the aim of maximal cytoreduction is the main predictor of overall survival in ovarian carcinoma. However, there are high risk sites of tumor recurrence, and the perihepatic region, especially the point where the ligamentum teres hepatis enters the liver parenchyma under the hepatic bridge (pont hepatique), is one of them. This video demonstrates the resection of the ligamentum teres hepatis both in a cadaveric model and in a patient with ovarian cancer. © 2019 by the Turkish-German Gynecological Education and Research Foundation.

Introduction
The falciform ligament divides the liver into the right and left
lobes on the antero-superior part of portoumbilical fissure
where the ligamentum teres hepatis (umbilical ligament of
liver/round ligament of liver) attaches to the visceral surface.
Due to the distribution pattern of the portal vein and hepatic
veins, the liver is divided into eight functional segments (1).
The umbilical fissure exists between liver segments III and IVb,
and the umbilical ligament lies there. The liver parenchyma
over this structure varies in thickness, and in some patients
the umbilical ligament will be completely visible, which allows
broad exposure until its entrance into the liver. Paul Sugarbaker
defined this parenchyma surrounding the umbilical ligament
as the ‘pont hepatique/hepatic bridge,’ which creates a tunnel
(2,3).
Mucinous ovarian or gastrointestinal carcinoma, appendiceal
carcinoma, mesothelioma or a serous ovarian cancer may have
a widely disseminated recurrence on the peritoneal surfaces.
The complicated surgical anatomy of the liver and perihepatic
tissues limits the easy detection of tumor implants; eventually,
good exposure of the abdominal cavity is needed to excise all
the visible tumor implants, especially on high-risk fields such as
the end part of the ligamentum teres hepatis under the hepatic
bridge (4).
There is no risk of injuring any structures while cutting the
hepatic bridge. However, if the ligament is deeply attached to
the bottom of the liver parenchyma, while dissecting the end
point, care should be taken not to damage the left hepatic
artery or the left hepatic duct over the hepatoduodenal
ligament, which is covered by the peritoneal lining of lesser sac
(3,5). Routine resection of the ligamentum teres hepatis may
increase morbidity (6); however, in patients with peritoneal
carcinomatosis, the base of the ligamentum teres hepatis
should be observed under the hepatic bridge because it is a
continuation of peritoneal tissue.

Abstract
Resection of all tumor implants with the aim of maximal cytoreduction is the main predictor of overall survival in ovarian carcinoma. However,
there are high risk sites of tumor recurrence, and the perihepatic region, especially the point where the ligamentum teres hepatis enters the liver
parenchyma under the hepatic bridge (pont hepatique), is one of them. This video demonstrates the resection of the ligamentum teres hepatis

Introduction: Ovarian cancer is the leading cause of death among all gynecological malignancies. Most patients present with an advanced stage of the disease. The routes of spread in ovarian cancer include peritoneal dissemination, direct invasion, and lymphatic or hematogenous spread, with peritoneal and lymphatic spread being the most common among them. The flow direction of the peritoneal fluid makes the right subphrenic space a target site for peritoneal metastases, and the most frequently affected anatomical area in advanced cases is the right upper quadrant. Complete cytoreduction with no macroscopically visible disease is the most important prognostic factor. Methods: We reviewed published clinical anatomy reports associated with surgery of the liver in cases of advanced ovarian cancer. Results: The disease could disseminate anatomical areas, where complex surgery is required-Morrison's pouch, the liver surface, or porta hepatis. The aim of the present article is to emphasize and delineate the gross anatomy of the liver and its surgical application for oncogynecologists. Moreover, the association between the gross and microscopic anatomy of the liver is discussed. Additionally, the vascular supply and variations of the liver are clearly described. Conclusions: Oncogynecologists performing liver mobilization, diaphragmatic stripping, and porta hepatis dissection must have a thorough knowledge of liver anatomy, including morphology, variations, functional status, potential diagnostic imaging mistakes, and anatomical limits of dissection.

Simple Summary Ovarian cancer (OC), the most lethal gynecological malignancy, usually presents in advanced stages. Unlike other gynecological malignancies, advanced epithelial OC often spreads through peritoneal and lymphatic dissemination to the upper abdomen. Hence, OC necessitates complex surgical procedures usually involving the upper abdomen with the aim of achieving optimal cytoreduction without visible macroscopic disease. Omitting dissection of these particular areas can compromise complete cytoreduction. Neglected anatomical areas that may harbor tumor residues include the omental bursa; Morison’s pouch; the base of the round ligament of the liver and hepatic bridge; the splenic hilum; and suprarenal, retrocrural, cardiophrenic and inguinal lymph nodes. These areas are commonly involved and should be rigorously evaluated in every patient with advanced epithelial OC as they often preclude optimal cytoreduction. This article provides a meticulous anatomical description of neglected anatomical sites concealing possible residual disease during OC surgery and describes surgical steps essential for the dissection of these “neglected” areas. Abstract Ovarian cancer (OC), the most lethal gynecological malignancy, usually presents in advanced stages. Characterized by peritoneal and lymphatic dissemination, OC necessitates a complex surgical approach usually involving the upper abdomen with the aim of achieving optimal cytoreduction without visible macroscopic disease (R0). Failures in optimal cytoreduction, essential for prognosis, often stem from overlooking anatomical neglected sites that harbor residual tumor. Concealed OC metastases may be found in anatomical locations such as the omental bursa; Morison’s pouch; the base of the round ligament and hepatic bridge; the splenic hilum; and suprarenal, retrocrural, cardiophrenic and inguinal lymph nodes. Hence, mastery of anatomy is crucial, given the necessity for maneuvers like liver mobilization, diaphragmatic peritonectomy and splenectomy, as well as dissection of suprarenal, celiac, and cardiophrenic lymph nodes in most cases. This article provides a meticulous anatomical description of neglected anatomical areas during OC surgery and describes surgical steps essential for the dissection of these “neglected” areas. This knowledge should equip clinicians with the tools needed for safe and complete cytoreduction in OC patients.

Aim: To determine if cholecystectomy and liver's round ligament removal is a necessary step during cytoreductive surgery (CRS) and HIPEC METHODS: This was a retrospective observational study based on records from 180 patients treated in our center from 2005 to 2014. All patients have been offered CRS and HIPEC for peritoneal pseudomixoma (20 patients), peritoneal mesothelioma (7 patients), peritoneal carcinomatosis from ovarian cancer (66 patients), colorectal cancer (42 patients), gastric cancer (10 patients), mucinous adenocarcinoma of the appendix (28), and other abdominal malignancies (7 patients). We performed a cholecystectomy and we removed the round ligament of the liver in all patients, even if there wasn't a macroscopic tumor infiltration of the above anatomical structures. We reviewed the histological reports of all 180 patients. Results: Patients with peritoneal carcinomatosis from mucinous adenocarcinoma of the appendix were treated more aggressively, due to the macroscopic appearance of the disease. Histologic report show no evidence of metastases at the round ligament of the liver in 21, 4% of the patients that were treated with CRS although it was estimated to be involved based on the macroscopic examination at the time of surgery. Tumor involvement of the gallbladder was overestimated, macroscopically, at the same patients in 25% of the cases. In patients with peritoneal carcinomatosis from ovarian cancer, macroscopic appearance of the gallbladder may be delusive. In 25% of the above patients there was a microscopic tumor involvement of the gallbladder, although there was not macroscopic evidence of the disease. Conclusion: More extended cytoreductive surgery is needed in case of peritoneal carcinimatosis from ovarian cancer. In case of PC from mucinous adenocarcinoma of the appendix, it's difficult to calculate the extent of the disease and avoid unnecessary surgical excisions. More data is needed to confirm the above. Key words: Cytoreductive surgery, Gallbladder, HIPEC, Peritoneal carcinomatosis, Round ligament of the liver.

Background: The hepatic bridge forms a tunnel of liver parenchyma that may obscure peritoneal metastases associated with the round ligament. Visualization and then resection of nodules associated with this structure is necessary. Materials and methods: The incidence of a hepatic bridge and the extent that it covered the round ligament was determined in consecutive patients. Extent of coverage of the round ligament by the hepatic bridge was determined: Class 1 indicates up to one-third of the round ligament obscured, Class 2 up to two-thirds and Class 3 more than two-thirds. Results: In 102 patients in whom the round ligament of the liver could be completely visualized, 50 had a hepatic bridge. Class 1 was 22 (44%) of the bridges, Class 2 was 16 (32%) and Class 3 was 12 (24%). A hepatic bridge was more frequently present in 28 of 45 male patients (62%) vs. 22 of 57 female patients (38%). Conclusions: Approximately one-half of our patients having cytoreductive surgery for peritoneal metastases were observed to have a hepatic bridge. Up to 56% of these patients have Class 2 or 3 hepatic bridge and may require division of the hepatic bridge to completely visualize the contents of the tunnel created by this structure.

The pont hepatique (also called the pons hepatis and hepatic bridge) connects segments 3 and 4B of the liver and forms a tunnel in which occult metastatic tumor can occur in peritoneal malignancies including ovarian cancer. A thorough knowledge of the anatomy of this area and procedure for dividing the pont, exposing the tunnel and resecting and ablating tumors within, can contribute to complete cytoreductive surgery. A 36yr old lady underwent laparotomy for a mucinous carcinoma of the ovary of low malignant potential with pseudomyxoma peritonei. As part of her intra-operative assessment the pont hepatique was divided using a tissue sealing energy device to expose the underlying tunnel. Care was taken to avoid damaging the left hepatic artery which passes close to the superior end of the pont. Mucinous deposits were noted on the peritoneum of the floor of the tunnel and on the terminal portion of the ligamentum teres. The ligamentum teres was isolated, ligated and divided close to its termination taking care not to damage branches of the left portal vein and left hepatic artery supplying segments 3 and 4B of the liver which run close to the base. Bleeding from hepatic parenchyma which formed the pont was controlled and residual mucinous deposits were ablated with the argon beam coagulator. The patient was then treated with hyperthermic intraperitoneal chemotherapy with mitomycin for 90minutes. The postoperative course was uncomplicated.

Cancer dissemination on peritoneal surfaces can be treated by cytoreductive surgery and perioperative intraperitoneal chemotherapy. To maximize benefits a complete cancer removal precedes the chemotherapy treatments. During cytoreductive surgical procedures a variable bridge of liver parenchyma that covers the round ligament of the liver was observed. This bridge of liver parenchyma is referred to as the pont hepatique (hepatic bridge). Failure to remove tumor nodules from beneath the pont hepatique will result in recurrent disease. If the pont hepatique is opened as part of a cytoreductive procedure for peritoneal dissemination of cancer, cancer nodules will often be found beneath. These nodules can be removed using electrosurgical dissection taking care to avoid damage to the left hepatic artery. Division of the pont hepatique and removal of cancer nodules around and on the round ligament will facilitate a complete cytoreduction.

A successful new treatment for a particular disease may change the natural history of that disease as patients go on to longer survival. The goal of this study was to investigate the porta hepatis as a site of recurrence of appendiceal mucinous neoplasms. A prospective database on patients with peritoneal dissemination of mucinous appendiceal neoplasms has been maintained for 21 years. In patients with complete cytoreduction, disease progression/recurrence in and around the porta hepatis has been noted as a new manifestation of this disease. In 710 patients treated for mucinous appendiceal cancer with a complete cytoreduction, 140 developed recurrent disease. Seven patients (5%) had disease recurrence in and around the porta hepatis. Four of the seven had biliary obstruction and three had masses within the liver hilum not causing bile duct obstruction. Four of the seven patients were successfully palliated by surgical procedures within the liver and biliary tree. Two patients were successfully palliated using a biliary stent and one patient was not treated. Progression of mucinous neoplasms within the porta hepatis may be related to imperfect cytoreduction technique. Reoperative surgical treatment and biliary stents were beneficial in some of these patients.

The liver, the largest organ in the body, has been misunderstood at nearly all levels of organization, and there is a tendency to ignore details that do not fit the preconception. A complete presentation of the surgical anatomy of the liver includes the study of hepatic surfaces, margins, and fissures; the various classifications of lobes and segments; and the vasculature and lymphatics. A brief overview of the intrahepatic biliary tract is also presented.
