Modified hepatic left lateral lobe inversion in laparoscopic proximal gastrectomy: An analysis of 13 cases.

In laparoscopic proximal gastrectomy (LPG), the prolapse of the hepatic left lateral lobe near the lesser curvature and esophageal hiatus can obstruct the field of vision and operation. Therefore, it is necessary to retract or obstruct the hepatic left lateral lobe to ensure a clear field of vision. To investigate the safety and clinical efficacy of the modified hepatic left lateral lobe inversion technique for LPG. A retrospective analysis was conducted on the clinical data of 13 consecutive patients with early-stage upper gastric adenocarcinoma or adenocarcinoma of the esophagogastric junction treated with LPG from January to December 2023 at the Department of Gastrointestinal Surgery, Second Affiliated Hospital of Fujian Medical University. The modified hepatic left lateral lobe inversion technique was used to expose the surgical field in all patients, and short-term outcomes were observed. In all 13 patients, the modified hepatic left lateral lobe inversion technique was successful during surgery without the need for re-retraction or alteration of the liver traction method. There were no instances of esophageal hiatus occlusion, eliminating the need for forceps to assist in exposure. There was no occurrence of intraoperative hepatic hemorrhage, hepatic vein injury, or hepatic congestion. No postoperative digestive complications of Clavien-Dindo grade ≥ II occurred within 30 days after surgery, except for a single case of pulmonary infection. Some patients experienced increases in alanine aminotransferase and aspartate aminotransferase levels on the first day after surgery, which significantly decreased by the third day and returned to normal by the seventh day after surgery. The modified hepatic left lateral lobe inversion technique has demonstrated satisfactory results, offering advantages in terms of facilitating surgical procedures, reducing surgical trauma, and protecting the liver.

Laparoscopic management of a left hepatic vein injury during one -step laparoscopic Roux-en-Y gastric bypass after adjustable gastric banding removal: A case report.

Introduction and importanceThe occurrence of a left hepatic vein injury during laparoscopic removal of an adjustable gastric band is exceptional and should be known by any surgeon approaching the hiatal region. We report here the laparoscopic control of such a wound.Case presentationA 39-year-old morbidly obese woman (body mass index 47.7 kg/m2) presented the failure in weight loss following a laparoscopic adjustable gastric banding. It was decided to perform a one-step laparoscopic Roux-en-Y gastric bypass. Laparoscopic exploration showed post-surgical tissular retraction and adhesions. After the lap-band™ removal the left hepatic vein was accidentally bluntly injured while freeing adhesions between left hepatic lobe and the stomach. After a direct hemorrhagic control, intraoperative diagnosis of left hepatic vein injury was confirmed. A laparoscopic repair was performed by two running sutures using absorbable monofilament 4/0. Then, a Roux-en-Y gastric bypass was performed without any other complications. Operative time was 119 min; intraoperative blood loss was estimated as 200 cm3. No blood transfusion was necessary. The total hospital stay was 48 h. The excess weight lost after 10 years was 87,9%.Clinical discussionAdjustable gastric band can modify anatomic landmarks, leading to a wrong dissection path, with possibility of left hepatic vein injury.ConclusionThe left hepatic vein injury can occur during revisional surgery for laparoscopic adjustable gastric banding failure. Its laparoscopic management can be done safely, in trained hands without increasing morbidity.

Case report: direct suture repair of inferior vena cava to rescue a stab patient with hepatic and caval injury through left hepatectomy and total vascular exclusion

BackgroundThe mortality of abdominal vena caval injuries is as high as 50–80%. Yet, there were few reports on how to repair injured inferior vena cava (IVC). This report presents a method of vena caval repair in a case of penetrating retrohepatic IVC injury, requiring hepatic resection and total vascular exclusion (TVE).Case presentationThe patient was a 20-year-old man with a stab wound in the epigastrium. An emergency laparotomy was performed in the emergency room, and a stab incision on the left liver was detected. As the Pringle’s maneuver did not reduce bleeding, hepatic vein injury was suspected, and left hemihepatectomy was performed to confirm the bleeding point. After the hepatectomy, laceration was still evident deeper into the resection, and IVC injury was suspected. The bleeding was temporarily controlled by tentative hepatorrhaphy and gauze packing, and the initial damage control surgery was terminated. Definitive surgery was performed on the third postoperative day. The lacerated point was observed under TVE, and the laceration penetrated the retrohepatic IVC through its posterior wall. The slit of the posterior wall was sutured first, followed by suturing of the anterior wall of the IVC. Finally, the lacerated liver was closed with hepatorrhaphy. TVE was removed, and the massive bleeding was successfully controlled.ConclusionIn severe liver injuries involving the retrohepatic IVC, hepatic resection and TVE may be useful for ensuring an optimized surgical field for repairing the injured IVC.

Comparative study on selective hepatic vascular exclsion and total hepatic vascular exclusion for hepatic trauma with major hepatic vein injury

Objective To compare the effect of selective hepatic vascular exclsion (SHVE) and total hepatic vascular exclusion (THVE) in the treatment of hepatic trauma with major hepatic vein injury. Methods A retrospective case control study was conducted to analyze the clinical data of 42 patients with hepatic trauma accompanied by hepatic vein injury admitted to multiple centers from April 2000 to December 2017. There were 30 males and 12 females, aged 14-65 years [(40.2±18.8)years]. Blood flow exclusion was operated through HVE in 22 patients (SHVE group) and through THVE in 20 patients (THVE group). SHVE group included 22 patients (16 males and six females), aged (40.1±19.4)years. There were 10 patients with grade IV and 12 with grade V according to American Association of Traumatic Surgery (AAST) classification of liver injury. In terms of the hepatic vein injury, there were 13 patients with type I, eight with type III, and one with type IV. THVE group included 20 patients (14 males and six females), aged (39.9±18.2)years. There were nine patients with grade IV and 11 with grade V according to AAST classification of liver injury. In terms of the hepatic vein injury, there were 11 patients with type I, seven with type III, and two with type IV. The operation approach, operation time, hepatic warm ischemia time, blocking time of hepatic vein blood flow, amount of abdominal hemorrhage, intraoperative blood loss, postoperative blood loss, intraoperative infusion, total blood transfusion, length of ICU stay after operation, length of hospital stay after operation, function of liver and kidney after operation, incidence of complications and mortality were compared between the two groups. Results There were no significant differences in the amount of abdominal hemorrhage, intraoperative blood loss, postoperative blood loss, perioperative blood transfusion, surgical procedure, and postoperative liver and kidney function between the two groups (P>0.05). The THVE group had significantly longer operation time, hepatic warm ischemia time, hepatic venous blood flow blocking time, postoperative ICU time and postoperative hospital stay than the SHVE group (P<0.05). The amount of infusion in the SHVE group was less than that in the THVE group (P<0.05). The incidence of complications in SHVE group was 27% (6/22), lower than that in THVE group [60% (12/20)] (P<0.05). The mortality of SHVE group was 14% (3/22), lower than that of THVE group [45% (9/20)](P<0.05). Conclusions SHVE and THVE can effectively control bleeding in the treatment of hepatic trauma with main hepatic vein injury. SHVE has more advantages over THVE in shortening operation time, warm ischemia time of liver, blocking time of hepatic vein blood flow, ICU stay after operation, hospital stay after operation and reducing intraoperative infusion volume, and can reduce the incidence of complications and mortality.

Left hepatectomy with middle hepatic vein injury and videolaparoscopic repair

Left hepatectomy with middle hepatic vein injury and videolaparoscopic repair

Right Hepatic Vein Injury and Control during Laparoscopic Surgery

Background: Laparoscopic liver resection (LLR) has now been widely performed in experienced centers. One of the worse complications during this surgery, is the hepatic vein injury, because it may cause conversion, air embolization, fatal hemorrhaging, or even death. Methods: We present the video of a 70 Years old male, with a previous history of Colon Cancer, who develops Liver Metastases in the right lobe, one of the lesions is situated close to the origin of the right hepatic vein. The patient is proposed to surgery, he Underwent Laparoscopic Right Hepatectomy. Results: During the surgery the Right hepatic vein is injured, which cause important bleeding, in the video we can observe how to achieve temporary control of the bleeding and proceed to a definitive management, the surgery is ended and the patient recovers successfully. Conclusion: Laparoscopic liver resection is an advanced procedure that requires skillful surgeons trained in this techniques, Hepatic Vein Injuries is one of the worst complications of this surgery. The Backflow bleeding can be minimized with fluid restriction, muscular relaxation and the effect of pneumoperitoneum, but, the experience of the surgeon permits the initial temporary control through laparoscopic, and then, proceed to the definitive management of the complication via laparoscopy or laparotomy.

Modified liver hanging maneuver focusing on outflow control in pure laparoscopic left-sided hepatectomy.

Outflow control during laparoscopic liver resection necessitates the use of technically demanding procedures since the hepatic veins are fragile and vulnerable to damage during parenchymal transection. The liver hanging maneuver reduces venous backflow bleeding during deep parenchymal transection. The present report describes surgical outcomes and a technique to achieve outflow control during application of the modified liver hanging maneuver in patients undergoing laparoscopic left-sided hepatectomy. A retrospective review was performed of clinical data from 29 patients who underwent laparoscopic left-sided hepatectomy using the modified liver hanging maneuver between February 2013 and March 2017. For this hanging technique, the upper end of the hanging tape was placed on the lateral aspect of the left hepatic vein. The tape was then aligned with the ligamentum venosum. The position of the lower end of the hanging tape was determined according to left-sided hepatectomy type. The hanging tape gradually encircled either the left hepatic vein or the common trunk of the left hepatic vein and middle hepatic vein. The surgical procedures comprised: left lateral sectionectomy (n = 10); left hepatectomy (n = 17); and extended left hepatectomy including the middle hepatic vein (n = 2). Median operative time was 210min (range 90-350min). Median intraoperative blood loss was 200ml (range 60-600ml). Two intraoperative major hepatic vein injuries occurred during left hepatectomy. Neither patient developed massive bleeding or air embolism. Postoperative major complications occurred in one patient (3.4%). Median postoperative hospital stay was 7 days (range 4-15 days). No postoperative mortality occurred. The present modified liver hanging maneuver is a safe and effective method of outflow control during laparoscopic left-sided hepatectomy.

Technical Compensation for Hepatic Vein Injury during Robotic Single Site Cholecystectomy

This video describes an event that could occur during any cholecystectomy. To the best of our knowledge, this video is the first description of the technical compensation for hepatic vein injury during robotic single-site cholecystectomy (RSSC). A 61-year-old male with a 1.6 cm gallbladder stone sought to go through with RSSC. During dissection of gallbladder from the liver bed, the hepatic vein was unexpectedly exposed and injured. Using the angulated robotic needle holder, the injured hepatic vein was repaired with 5-0 prolene monofilament suture. Although there is a lack of EndoWrist movement in RSSC, suturing was feasible. The patient was discharged on the second postoperative day without complications. Incidental hepatic vein injury could be safely managed using RSSC and prevent the need for conversion to a conventional laparoscopic or open approach.

Retrograde laparoscopic resection of left side of the liver: a safe and effective way.

The safety and feasibility of retrograde laparoscopic resection of the left side of the liver. Ninety-three laparoscopic left hepatic lobe cases were selected between August 2010 and August 2014 from our institution. A retrospective cohort study was performed between the antegrade partial hepatectomy group (47 cases; dissection from the first porta hepatis to the second) and the retrograde partial hepatectomy group (46 cases; dissection from the second porta hepatis to the first), to compare the length of time needed for resection, the amount of bleeding, post-operative time in the hospital, and the incidence of major complications, such as bile leakage, abdominal abscess, and post-hepatectomy hemorrhage. All of the cases had a successful laparoscopic partial hepatectomy without the need for an intraoperative blood transfusion. Patients were able to ambulate on post-operative day 1 and tolerated a liquid diet on post-operative day 1 or 2. There were no statistical differences of post-operative hospital length of stay or incidence of major complications between the two groups. Both duration of resection and the amount of bleeding were less in the retrograde group than of those in the antegrade group, due to the lower incidence of hepatic vein injury in the retrograde group. Occlusion of both the inflow and outflow hepatic vessels combined with retrograde hepatectomy from the second porta hepatis to the first, demonstrated less hemorrhage and lower incidence of hepatic veins injury during laparoscopic partial hepatectomy.

Self-expanding foam for prehospital treatment of severe intra-abdominal hemorrhage

Noncompressible abdominal bleeding is a significant cause of preventable death on the battlefield and in the civilian trauma environment, with no effective therapies available at point of injury. We previously described the development of a percutaneously administered, self-expanding, poly(urea)urethane foam that improved survival in a lethal Grade V hepatic and portal vein injury model in swine. In this study, we hypothesized that survival with foam treatment is dose dependent. A high-grade hepatoportal injury was created in a closed abdominal cavity, resulting in massive noncompressible hemorrhage. After injury, the animals were divided into five groups. The control group (n = 12) was treated only with fluid resuscitation, and four polymer groups received different dose volumes (Group 1, n = 6, 64 mL; Group 2, n = 6, 85 mL; Group 3, n = 18, 100 mL; and Group 4, n = 10, 120 mL) in addition to fluids. Ten minutes after injury, the foam was percutaneously administered, and animals were monitored for 3 hours. Survival with hepatoportal injury was highest in Group 4 (90%) and decreased in a dose-dependent fashion (Group 3, 72%; Group 2, 33%; Group 1, 17%). All polymer groups survived significantly longer than the controls (8.3%). Hemorrhage rate was reduced in all groups but lowest in Group 4 versus the control group (0.34 [0.052] vs. 3.0 [1.3] mL/kg/min, p < 0.001). Increasing foam dose volume was associated with increased peak intra-abdominal pressure (88.2 [38.9] in Group 4 vs. 9.5 [3.2] in the controls, p < 0.0001) and increased incidence of focal bowel injuries. The self-expanding foam significantly improves survival in a dose-dependent fashion in an otherwise lethal injury. Higher doses are associated with better survival but resulted in the need for bowel resection.

Selective hepatic vascular exclusion versus Pringle manoeuvre in liver resection for tumours encroaching on major hepatic veins

Control of bleeding is crucial during liver resection, and several techniques have been developed to achieve this. This study compared the safety and efficacy of selective hepatic vascular exclusion (SHVE) and Pringle manoeuvre in partial hepatectomy for liver tumours compressing or involving major hepatic veins. All patients undergoing liver resection between January 2003 and December 2010 for liver tumours compressing or involving one or more major hepatic veins were identified retrospectively from a prospective institutional database. Either SHVE or Pringle manoeuvre was used to minimize blood loss during hepatectomy. Data on demographics and the intraoperative and postoperative course were analysed. From the database of 3900 patients, 1420 were identified who underwent liver resection for tumours encroaching on major hepatic veins using either SHVE (550) or the Pringle manoeuvre (870). Intraoperative blood loss (mean(s.d.) 480(210) versus 830(340) ml; P = 0·007) and transfusion requirements (mean(s.d.) 1·3(0·6) versus 2·9(1·4) units; P = 0·008) were significantly less in the SHVE group. In the Pringle group, hepatic vein injury resulted in major intraoperative bleeding of over 1000 ml in 65 patients (7·5 per cent) and air embolism in 14 (1·6 per cent), and three patients (0·3 per cent) died during surgery, whereas there was no major bleeding, air embolism or intraoperative death in the SHVE group. Postoperative liver failure, multiple organ failure and in-hospital death were significantly more common in the Pringle group (P = 0·019, P = 0·032 and P = 0·004 respectively). SHVE was more efficacious than the Pringle manoeuvre in minimizing intraoperative bleeding and air embolism during partial hepatectomy for tumours encroaching on major hepatic veins, and decreased the postoperative liver failure rate.

Liver transplantation as an ultimate step in the management of iatrogenic bile duct injury complicated by secondary biliary cirrhosis

This report summarizes a single center's experience with liver transplantation (LT) performed for secondary biliary cirrhosis resulting from iatrogenic bile duct injury (BDI) sustained during cholecystectomy. Secondary biliary cirrhosis was the indication for LT in 5 (1.7%) out of 300 LTs performed in our center between Feb 2002 and April 2011. We analyzed the medical history of the patients, perioperative course and outcome following LT. The BDI was classified as Strasberg A in 1 case, B in two cases, and E in 2 cases. There was no hepatic arterial or portal vein injury in any patient. All of the surgical repairs prior to the development of cirrhosis were performed in general surgical units. The median time between BDI and listing the patient for LT was 11 years. The cadaveric whole-organ LT was done in all patients using the Piggy-Back technique. All patients are alive with a median follow-up of 53 months. Liver transplantation in patients with secondary biliary cirrhosis appears to result from a series of inadequate multiple surgical repairs following BDI. The immediate referral of such patients to centers with bile duct surgery experience is crucial.

Intraoperative injuries during liver resection: analysis of 1,005 procedures

PurposeRisk of liver resection has been well investigated in many studies. However, the problem of intraoperative injuries is rarely mentioned. The aim of this study was to assess the incidence, the type, and management of intraoperative injuries during liver resection.MethodsA total of 1,005 liver resections between 2004 and 2009 were included in this retrospective investigation. We analyzed the incidence of intraoperative injuries, risk factors, and an impact on patients’ clinical outcome.ResultsThe overall incidence of intraoperative injuries was 4.4% (44 of 1,005). Injuries of the diaphragm (1.6%, 16 of 1,005) and hepatocaval junction (1%, 10 of 1,005) were the most frequent. In multivariate analysis, tumor recurrence (p = 0.0199) and tumor size (p = 0.0317) were the only independent risk factors for diaphragm injuries, whereas the extent of resection (p = 0.0007) was the only independent risk factor for caval or hepatic vein injuries. Injuries of the inferior vena cava or hepatic veins significantly increased perioperative mortality (p = 0.0005).ConclusionsMinor injuries causing no significant complications were the most frequent. However, prevention and proper management of the rare injuries of hepatocaval junction are essential to avoid increased mortality in major liver resections.

Manifestation of dynamic contrast-enhanced CT of hepatic injury in rabbits

Objective To analyze the features of dynamic contrast-enhanced CT of blunt hepatic injury in rabbits. Methods The model of blunt hepatic injury was established in 40 New Zealand white rabbits with a steel ball falling down to the xiphoid process of the animals. Plain CT scan and dynamic contrast-enhanced CT scan (Hispeed spiral CT/2i, GE, America) of the liver were performed. Arterial,portal and balanced phases were respectively at 8-10 s, 35-40 s and 120-150 s after initiation of the contrast medium injection. The non-enhanced and enhanced images were compared in aspects of location and range of injury, tear of the liver capsule, active bleeding, involvement of the main hepatic veins and CT features of abdominal hemorrhage, which was further compared with the results of gross anatomy. Results The rate of plain CT scan was obviously lower than that of dynamic contrast-enhanced CT scan,which defined single tear in 13 patients, multiple lacerations in 18, liver subcapsular hematoma in seven,liver hematoma in nine, liver coated gap in 17, active bleeding in nine and main hepatic vein injury in five, with coincidence rates with the results of gross observation for 13/13,18/18,7/9,9/9,25/30,9/5and 5/4 respectively. According to Moore' s classification, CT/Laparotomy performed from grade Ⅰ to grade Ⅵ were 5/4 patients at grade Ⅰ , 15/13 at grade Ⅱ, 9/11 at grade, 5/6 at grade Ⅳ, 1/2 at grade Ⅴ, O at grade respectively. Conclusion Dynamic contrast-enhanced CT scan, especially at portal and balanced phases, is of great value for diagnoses of liver injuries and determination of injury severity.

Imagerie des voies biliaires opérées

For a long time, imaging of the biliary tract after surgical procedures was performed with invasive procedures such as endoscopic retrograde cholangiopancreatography or percutaneous transhepatic cholangiography. Due to recent advances in diagnostic imaging, non-invasive techniques are now favored. While US remains the initial imaging modality, it is frequently followed by CT and/or MRCP. Image interpretation should always be performed in keeping with clinical and laboratory findings as well as the type of surgical procedure. The most appropriate imaging modality is selected based on these data. In patients with jaundice or biliary tract stenosis, MRCP, with use of an optimal technique and 3D acquisition, is the imaging modality of choice. In non-jaundiced patients with non-distended biliary tract and suspected bile leak, MRCP should be completed by the injection of a liver-specific contrast agent with biliary excretion to achieve non-invasive biliary tract opacification. In patients with malignancy, CT is preferred due to its high spatial resolution and ability to demonstrate small anastomotic tumor recurrences. CT should also be performed in patients with suspected hepatic artery or portal vein injury in addition to biliary tract injury or to detect distant complications.

Modified Technique of Mesh Hepatorrhaphy for Management of Juxtahepatic Venous Injury in a Case of Blunt Liver Trauma: A Case Report.

The liver is the most frequently injured organ in cases of blunt abdominal trauma. Injuries to the caudate lobe are rarely isolated and usually associated with retrohepatic caval injury or hepatic vein injury. The management of the associated vascular injuries is usually difficult owing to the short courses of the hepatic veins and the difficulty in obtaining proximal and distal control of the suprarenal and suprahepatic inferior vena cava - hence the frequency of perihepatic packing in the management of caudate lobe and hepatic venous injuries. We present here a rare case of the failure of perihepatic packing to effectively control hemorrhage from blunt injury to the caudate lobe and retrohepatic vena cava. A case of blunt abdominal trauma with injury to the caudate lobe and retrohepatic venous injury was initially managed with perihepatic packing. The patient developed hemorrhage 48 h after pack removal, which was then successfully managed with mesh hepatorrhaphy of the caudate lobe.

Left hepatic vein injury during laparoscopic antireflux surgery for large para-oesophageal hiatus hernia

Although the advent of laparoscopic fundoplication has increased both patient and physician acceptance of antireflux surgery, it has become apparent that the laparoscopic approach is associated with an increased risk of some complications and as well as the occurrence of new complications specific to this approach. One such complication occurred in our patient who had intra-operative left hepatic vein injury during laparoscopic floppy Nissen fundoplication for large para-oesophageal rolling hernia. With timely conversion to open procedure, the bleeding was controlled and the antireflux and the procedure were completed uneventfully. However, this suggests that even with an experience in advanced laparoscopy surgery, complications can occur. Clear understanding of the normal and pathologic anatomy and its variations facilitates laparoscopic surgery and should help the surgeon avoid complications. The incidence of some of these complications decreases as surgeons gain experience; however, new complications can arise due to the increase in such procedures.

Hepatic Vein Injury During Laparoscopic Cholecystectomy: The Unappreciated Proximity of the Middle Hepatic Vein to the Gallbladder Bed

Uncontrollable hemorrhage during laparoscopic cholecystectomy occurs in 0.1% to 1.9% of all cases, with 88% originating from the gallbladder bed. The anatomical proximity between major branches of the middle hepatic vein and the gallbladder bed, and hence the risk of intraoperative bleeding, is unclear. CT scans of 20 random patients were retrospectively reviewed to identify the closest distance between branches of the middle hepatic vein and the gallbladder bed. The vein diameter was also recorded. Risk factors for intraoperative bleeding during laparoscopic cholecystectomy were also retrospectively reviewed. Large branches (mean diameter = 2.1 mm) of the middle hepatic vein are directly adjacent to the gallbladder bed in 10% of patients. An additional 10% of cases also possess branches within 1 mm of the gallbladder bed. Chronically scarred and contracted gallbladder disease may increase the risk of significant bleeding, requiring conversion. Twenty percent of all cases will display a large branch of the middle hepatic vein adherent or immediately adjacent to the gallbladder fossa. These patients are at increased risk for intraoperative bleeding. Furthermore, contracted gallbladders with evidence of chronic disease may be at increased risk for significant hemorrhage.

Exclusão vascular do fígado em lesões venosas hepáticas complexas

Injuries to the main hepatic veins carry a very high mortality rate, regardless of the technique used for repair. Isolated reports of survivors have, for the most part, been managed by hepatic vascular exclusion (EVE) techniques, usually with an atriocaval shunt. Herein we report a case of a severe intrahepatic major hepatic vein injury successfully managed with EVE.
