Video Case Report, No. 2 2023
Article DOI: 10.21614/sgo-v.28-a.576

Introduction: Gastrointestinal stromal tumors frequently spread via hematogenous route to the liver or through peritoneal seeding in the abdominal cavity. Once metastization has occurred neither surgery alone nor systemic therapy can successfully accomplish persistent malignancy control. However, a grouping of both approaches may potentially achieve disease stabilization and significantly improve overall survival.

Case presentation: We describe the case of a 61-year-old male patient who had presented a large gastric GIST with tumor rupture seven years before. He w....[more] Read article

Cervical cancer is the fourth most common gynecological malignancy. It is a major health problem commonly affecting women in a young age. It is well known that the majority of cervical cancer cases are related to human papilloma virus. Therefore, in Europe the rate of cervical cancer is expected to decrease due to human papilloma virus vaccination (1-3). However, the discrepancy in cervical cancer cases is clearly seen between Eastern and Western European countries. Moreover, the estimated age-standardized incidence rate of cervical cancer is the highest in Bulgaria among all European countries (1-3). Surgery is the standard trea....[more] Read article

Video Surgical Technique, No. 4 2022
Article DOI: 10.21614/sgo-522

Traumatic diaphragmatic hernia (TDH) is an uncommon disease, with an incidence of about 0.5% and is usually associated with penetrating or blunt thoracoabdominal trauma (1). It is often associated with other thoracoabdominal, brain and musculoskeletal injuries, being a diagnostic and therapeutic challenge (2). These injuries worsen the prognosis, with a mortality of up to 31% (2, 3). Chest X-rays with bowel contrast studies and CT scans of the chest and the abdomen are a useful diagnostic tool for detecting TDH, being the latter more specific (4). The treatment involves repair of the diaphragmatic defect with or without a mesh, using a transthoracic and/....[more] Read article

Introduction: Several interposition techniques have been described for reconstruction after total gastrectomy in FAP patients, in open (1) and laparoscopic assisted surgery (2,3,4). The Longmire technique has the advantage of allowing all the food to pass through the duodenum and better absorption of nutrients, such as iron (5). Here, we describe the use of a pedicled isoperistaltic jejunal flap interposition technique to reconstruct the digestive tract after total gastrectomy, fully performed by laparoscopic approach, in a patient with FAP that had previous total colectomy. Our patient was a 68-year-old woman, with “MUTYH-Associated Polyposis (MAP)”....[more] Read article

Pancreatic adenocarcinoma has a poor prognosis, even after R0 resections. Metachronous disease usually arises as distant or regional metastasis, but local recurrence is infrequent. 66 year-old male patient with a subclinical pancreatic remnant lesion suspected to be malignant 10 years after duodenopancreatectomy for invasive mucinous cystoadenocarcinoma. After distant metastatic disease was ruled-out, laparoscopic distal pancreatectomy was performed. Pathology revealed a non-invasive intraductal papillary mucinous neoplasm (IPMN).
The decision to resect metachronous disease after pancreatic cancer surgery remains under debate, based on the type of recurrence. Pancreatic remnant lesions can be true recurrences or new primary tu....[more] Read article

Article DOI: 10.21614/sgo-25-2-93
The Glissonean pedicle approach in liver surgery provides new knowledge of the surgical anatomy of the liver and advances the technique of liver surgery. Extrafascial dissection of Glissonean pedicle without opening the liver substance, proposed by Takasaki, represents an effective and safe technique of anatomic liver resection.
Presented approach allows early and easy ischemic delineation of appropriate anatomic liver territory (hemiliver, section or segment) to be removed with selective inflow vascular control. It is not time consuming and it is very useful in re-resection, as well as oncological reasonable. According to the Sugioka's proposal, for technical standardization, it is important to recognize the four anatomical landmarks; the Arantius plate, the umbilical plate, the cystic plate and t....[more] Read article

Isolated caudate lobectomy (ICL) is technically demanding and its surgical techniques are not standardized. Herein, we describe our method of open and laparoscopic ICL by the extrahepatic Glissonean pedicle approach (GPA) and hepatic vein (HV) root-at first one-way parenchymal resection, which are both based on Laennec's capsule.
Firstly, all the Glissonean pedicles of the caudate lobe are isolated and divided extrahepatically without parenchymal dissection. We have devised two different techniques for the extrahepatic pedicle control. One is "the central hilar technique", where all the major hilar pedicles are utilized to isolate caudate pedicles, and the other is "the left-to-right tracking technique", where the caudate pedicles are serially divided along the hilar plate from the left to the right sides.

Anatomic resection of the segment VIII (SVIII) of the liver (segmentectomy VIII) is technically demanding either in open or laparoscopic procedure. Our approaches to anatomic liver resections are composed of the extrahepatic Glissonean pedicle approach (GPA) to isolate hilar pedicles and hepatic vein (HV) root-at first one-way resection of liver parenchyma in the cranio-caudal direction starting from the landmark HV root.
Both techniques are based on Laennec's capsule. Herein, we describe our standardized techniques for open and laparoscopic segmentectomy VIII. The standardized GPA to the Glissonean pedicle of SVIII (G-VIII) starts with cystic plate cholecystectomy and isolation of the anterior section pedicle by detaching the pedicle sheath from the Laennec's capsule.
Isolation of segment V pedicle facilitates that of G-VIII using the subtr....[more] Read article

Laparoscopic central bisectionectomy (LCBS) is a highly advanced procedure for centrally located liver tumors. According to our approaches for anatomic liver resection composed of the Laennec's capsule-based extrahepatic Glissonean pedicle approach (GPA) and hepatic vein (HV) root-at first one-way parenchymal resection, we have standardized techniques for LCBS.
The extrahepatic GPA starts with cystic cholecystectomy facilitating extrahepatic isolation of the anterior section pedicle (G-ant), which is ligated. The segment IV pedicle (G-IV) is isolated extrahepatically.
Under occlusion of G-ant and G-IV, parenchymal dissection starts from exposing the root of middle hepatic vein (MHV) and continues in the cranio-caudal direction along the umbilical fissure vein, according to the left demarcation line. During parenchymal dissection, G-IV and MHV are divided.

Laparoscopic left hemihepatectomy (LLH) is one of the major hepatectomy procedures and its surgical techniques are not well standardized. According to our surgical strategies for anatomic liver resections, which are composed of the extrahepatic Glissonean pedicle approach (GPA) and hepatic vein (HV) root-at first one-way parenchymal dissection, we have standardized the surgical techniques for LLH.
Both approaches are based on the anatomical background of Laennec's capsule. The right and left sides of the root of the Glissonean pedicle including the umbilical portion of the portal vein (G-UP) are dissected with Laennec's capsule preserved on the liver parenchyma.
The G-UP is isolated extrahepatically and divided using a stapler. The common trunk of the left hepatic vein (LHV) and middle hepatic vein (MHV) is exposed from the left cranio-dorsal side and LHV is divided at its root.

Laennec's capsule is a proper membrane of the liver, first described by Rene T. H. Laennec in 1802, covering not only the entire surface of the liver but also the intrahepatic parenchyma surrounding the Glissonean pedicles and the hepatic veins (HVs).
It is an essential structure for establishing liver resection, especially anatomic liver resection, which involves the isolation of the extrahepatic Glissonean pedicles and the exposure of the main HVs. Regarding the location of the capsule, Laennec and Couinaud described it as adjacent to the confluence of the main HVs.
Whereas, Hayashi revealed it to be around the peripheral branches. Recently, Kiguchi first reported that Laennec's capsule consists of two layers and proposed novel surgical procedures using this concept. Yet, its existence is still debated.
Herein, we show the precise anatomy and histology of Laennec's capsule around the HVs including its twola....[more] Read article

Article DOI: 10.21614/sgo-25-2-67
Background: Glissonean pedicle isolation is a very useful procedure during a laparoscopic anatomic hepatectomy (LAH); however, few studies have reported the precise layer structure around a Glissonean pedicle.
The aim of this study was to evaluate the layer structure around a Glissonean pedicle in cadaveric models and determine whether Glissonean pedicle isolation based on the layer structure can serve as a standard surgical procedure during a LAH.

Methods: From April 2017 to December 2019, LAHs were performed in 59 patients. Prior to the LAH, a cadaveric model was used to verify the layer structure around the Glissonean pedicle. The procedure was also performed in live patients during LAHs and pathologic verification was performed. In addition, we evaluated the short-term results of LAHs.

Results: Laennec's capsule covering the liver parenchyma was shown by histologic examination (Elastica van Gieson sta....[more] Read article

We proposed a novel comprehensive surgical anatomy of the liver based on Laennec's capsule in 2017, which contributed to the standardization of extrahepatic Glissonean pedicle isolationĂ¢?"the optimal method for Glissonean pedicle isolation without parenchymal destruction.
Thereafter, the scope of our concept included an extension to the hepatic vein and the plate system to establish the surgical technique of the anatomic liver resection that consisted of extrahepatic Glissonean pedicle isolation, exposure of the landmark hepatic vein, and parenchymal reresection to the optimum amount. The accumulated histological evidence supported our concept, employing elastic fiber staining as a means of visualization.
For the standardization of extrahepatic Glissonean pedicle isolation, it was necessary to accurately approach the six gates marked by four anatomical landmarks to enter a gap between the Glissonean pedicle and the Laennec's capsule that covers the liver parenchy....[more] Read article

Article DOI: 10.21614/sgo-24-6-320
Background: Hepatectomy is the potentially curative treatment for liver tumors. The most critical postoperative complication of extensive liver resection is post-hepatectomy liver failure (PHLF) due to insufficient future liver remnant (FLR). The ALPPS (Associating Liver Partition and Portal vein Ligation for Staged hepatectomy) effectively increases the resectability of inoperable liver tumors by achieving a rapid and an effective hypertrophy of the FLR, which lowers postoperative liver failure risk. However, this technique still carries on with high morbidity and mortality rate. Aim: To present the first case of total laparoscopic ALPPS for extended right hepatectomy which is shown in VDO resources. Our institute proposed this technique as a valid option aim to improve the outcomes of ALPPS procedure by careful patient selection.

Technique: Total laparoscopic ALPPS involves two stages. The first stage consisted in the ligation of the right portal branch and the partition of th....[more] Read article

Hepatic resection remains the only potentially curative treatment for patients with colorectal liver metastasis (CRLM) (1). Moreover, only15%-20% of patients with CRLM are suitable for surgical resection (2). Herein wepresent a video case-report of a radical laparoscopic central bisegmentectomy plus S3 subsegmentectomy for multiple liver metastasis after chemotherapy.
The patient was a 39-year-old man who was shown to have metachronous multiple liver metastases from sigmoid colon cancer. The size of the tumor in S3 was 7cm, and the size of the tumor in S4 S5 S8 was 13cm. At this point, it was judged that there was no indication for surgery, thuschemotherapy was started. ThemFOLFOX+panitumumabwas administered for 8 courses and FOLFILI+panitumumab was administered for 10 courses. The metastatic lesions showed a partial clinical response to the chemotherapy.
Because the tumors were limited in S3 and S4 5 8, a radical hepatectomy was thought to bepossible. A CT scan revealed that the tumor in S3was located near the r....[more] Read article
Limited Central Hepatectomy for Centrally Located Tumors: Is There a Place for Standardization?
Florin Botea, Alexandru Barcu, Adina Croitoru, Dana Tomescu, Irinel Popescu
Video Case Report, No. 3 2019
Article DOI: 10.21614/sgo-24-3-170
Anatomical central hepatectomy is technically demanding and is often excessive. It has an increased risk for insufficient remnant liver volume, especially in case of P8 dorsal pedicle for segment 7 and or P5 dorsal for segment 6, and or abnormal background liver. On the contrary, limited central hepatectomy (LCH) for centrally located tumors, based on preserving the P8 dorsal and some of P5 and P4 pedicles (depending on tumor placement) is conservative, and therefore has a low risk for insufficient remnant liver volume.
It is less technically demanding, when compared to anatomical central hepatectomy. The right side of the resection plane is driven along the P8 dorsal pedicle intersecting the P8 ventral pedicle and as few of the P5 pedicles as possible. The left side of the resection plane is established according to tumor placement anywhere in between the Cantlie's plane and the falciform ligament.

The video presents 5 cases that support the conclusion that LCH may be standardized, with good results, especially when using intraoperativ....[more] Read article
Living Donor Liver Transplant Using Dual Grafts

Video Case Report, No. 3 2019
Article DOI: 10.21614/sgo-24-3-162
Living donor liver transplant predisposes both the donor and the recipient to high risk of small residual liver volume (in donor) and small-for-size graft syndrome (in recipient) (1).
Both of these risks can be overcomed by using two grafts from two different donors; this procedure is called "Living donor liver transplant using dual grafts" (2).

We present a video case-report of a "Living donor liver transplant using dual grafts" performed in a 51 yo female recipient for VHB+VHD cirrhosis, MELD score 22.
She received two liver grafts, a left hemiliver (Donor 2 in the video) and a left lateral section (Donor 1 in the video). The combined GRWR was 1.05 ( 0.71 + 0.34). For a better understanding of the technique, both donation and back-table procedures were combined in the same split-screen, being followed by the left lateral section (Donor 1) and left hemiliver (donor 2) implantations. Both donors had no postoperative complications. After 12 months of follow-up, both donors and the recipient are alive, with normal liver function.
Dual-graft Living donor ....[more] Read article
