Spontaneous falciform ligament necrosis: A rare case report.

Spontaneous and isolated necrosis of the falciform ligament is a rare condition. A 55-year-old lady presented with sudden onset of epigastric pain, fever and vomiting. Laboratory studies revealed less than three-fold increase in serum amylase and lipase levels. Ultrasound examination and contrast enhanced computed tomography (CECT) revealed features suggestive of inflammation and necrosis of the falciform ligament involving ligamentum teres hepatis and extending to the lesser omentum with an adjacent minimal ill-defined collection. Then, conservative management was started. However, the symptoms did not resolve completely. Therefore, CECT scan was repeated 12 days later which showed findings similar to previous scan with expansion and organization of the collection anterior to lesser omentum with peripheral enhancement, suggestive of an abscess. A minimally invasive approach to treatment was adopted. Aspiration of the collection was performed under ultrasound guidance. This was followed by continuation of supportive management. The patient improved clinically and was discharged. This case study highlights the importance of imaging in the diagnosis of falciform ligament necrosis. An innovative minimally invasive approach to treatment in the form of ultrasound guided aspiration may be considered when a collection is present adjacent to the necrosed falciform ligament.

Pedicled falciform ligament flap use as an alternative surgical technique in peptic ulcer perforation repair: a case report and review of literature.

Peptic ulcer disease (PUD) affects ~4 million people globally. Peptic ulcer perforation (PUP) is a serious complication of PUD associated with high mortality and morbidity. Hence, a high index of clinical suspicion is crucial in diagnosing such cases. Here, we present a case of a 19-year-old male who presented with 4 days of severe abdominal pain, fever, and vomiting. On examination, signs of acute abdomen were evident, and an erect chest X-ray confirmed free air under the diaphragm. The patient underwent an emergency midline laparotomy, during which 1000 ml of purulent fluid was evacuated. A perforation measuring 8 × 8 mm2 was repaired using the falciform ligament due to the unavailability of adequate healthy omentum. His postoperative recovery was uneventful. This case report underscores the importance of considering the falciform ligament as a viable and effective alternative for the closure of PUP when the omentum is unavailable.

Falciform technique in laparoscopic revision of distal catheter obstruction: an evaluation.

Background: Ventriculoperitoneal (VP) shunting is a cornerstone treatment for hydrocephalus, a condition characterized by the abnormal accumulation of cerebrospinal fluid in the ventricles of the brain. Despite its efficacy, this procedure is associated with various complications, among which distal catheter obstruction poses significant challenges. This study aimed to evaluate the effectiveness of the 'falciform technique' in laparoscopic revision of distal catheter obstructions, offering a novel approach to mitigate this prevalent issue. Materials and methods: This study retrospectively analyzed 28 patients with VP shunt distal catheter obstructions who underwent laparoscopy-assisted shunt revision between January 2016 and June 2022. All of these were done using the 'falciform technique' with the fixation of the distal catheter to the falciform ligament in supra-hepatic space. Results: The most common etiology of primary shunt surgery was hydrocephalus, followed by intracranial hemorrhage (42.9%) and traumatic brain injury (32.1%). Normal pressure hydrocephalus occurs in 14.3% of cases. Fifteen patients (53.6%) required revision surgery within 1 year of index surgery. Thirteen patients (46.4%) underwent revision surgery more than 1 year after the index surgery, either as a first revision or subsequent revision. The average surgery time was 32.1±14.7 min and hospital stay was 4.2±1.8 days. After a mean follow-up period of at 20.3±8.7 months, except for three patients who died from other causes (two patients due to pneumonia and one due to exhaustion), there were no shunt-related complications in the remaining 25 patients. Conclusions: Laparoscopy with the application of 'falciform technique' is a safe and highly effective method in distal catheter obstruction revision following VP shunt.

Surgical management of right hepatectomy after coronary artery bypass grafting using the right gastroepiploic artery: a case report and literature review.

BACKGROUND: Coronary artery bypass grafting (CABG) using the right gastroepiploic artery (RGEA) is a well-established, safe procedure. However, problems with RGEA grafts in subsequent abdominal surgeries can lead to fatal complications. This report presents the first case of right hepatectomy for hepatocellular carcinoma after CABG using the RGEA. CASE PRESENTATION: We describe a case in which a right hepatectomy for an 81-year-old male patient with hepatocellular carcinoma was safely performed after CABG using a RGEA graft. Preoperatively, three-dimensional computed tomography (3D- CT) images were constructed to confirm the run of the RGEA graft. The operation was conducted with the standby of a cardiovascular surgeon if there was a problem with the RGEA graft. The RGEA graft had formed adhesions with the hepatic falciform ligament, necessitating meticulous dissection. After the right hepatectomy, the left hepatic lobe descended into the vacated space, exerting traction on the RGEA. However, this traction was mitigated by suturing the hepatic falciform ligament to the abdominal wall, ensuring stability of the RGEA. There were no intraoperative or postoperative complications. CONCLUSION: It is crucial to confirm the functionality and anatomy of the RGEA graft preoperatively, handle it gently intraoperatively, and collaborate with cardiovascular surgeons.

Focal necrosis of the falciform ligament as a rare cause of abdominal pain: A case report.

The falciform ligament, a peritoneal fold that anatomically separates the right and left lobes of the liver, may infrequently be a cause of patients' complaints. In very rare instances, fatty appendages of the falciform ligament may undergo torsion, resulting in fat infarction. Despite its rarity, falciform ligament pathologies often mimic common abdominal issues, leading to misdiagnosis. Herein, we report a case of inflammation and necrosis of the falciform ligament in a 72-year-old female. The patient presented with abdominal pain, a positive Murphy's sign, and elevated inflammatory markers. Imaging, including a computed tomography (CT) scan, was pivotal in confirming the diagnosis of falciform ligament necrosis. Contrary to the proposed surgical approach (resection of the falciform ligament) in some reported cases, conservative management (including analgesia, hydration, and antibiotics) proved successful in this case. This report emphasizes the importance of considering falciform ligament torsion in upper abdominal pain differential diagnoses and highlights the key role of imaging for accurate diagnosis.

Absence of Falciform Ligament Found During Laparoscopic Surgery: A Case Report.

Anatomic variants of hepatic ligaments are rare, and complications attributable to these variants may be difficult to diagnose. Our aim is to contribute to the literature surrounding the incidental finding of a congenital absence of the falciform ligament. We report the case of a 37-year-old man who underwent a laparoscopic cholecystectomy for acute cholecystitis. During the operation, the patient was noted to have an apparent absence of the falciform ligament attachment to the liver. The round ligament was attached from the liver to the anterior abdominal wall at the level of the umbilicus. The round ligament is inserted into the inferior surface of the liver as a thick, cordlike structure encased in fat. In rare cases, the small intestine can pass through a falciform ligament defect and become trapped while remaining within the peritoneal cavity, leading to difficult-to-diagnose internal hernias. This condition can lead to intestinal obstruction, incarceration, and strangulation. This directed our decision to divide the remaining round ligament at the liver and close to the abdominal wall. When defects of hepatic ligaments are found incidentally during laparoscopic surgery, these investigators recommend that the operating surgeon consider dividing the remaining ligament as a protective procedure to prevent complications such as internal hernias, intestinal obstruction, incarceration, and strangulation.

Isolated Inflammatory Necrosis of the Falciform Ligament: A Case Report with Review of Literature.

Inflammatory necrosis of the falciform ligament is an extremely rare cause of acute right upper quadrant pain. Due to overlapping symptoms with pathologies affecting the gall bladder and liver, this poses a diagnostic challenge with limited existing literature. Here, we report a case of a 62-year-old female patient presenting in the accident and emergency department with right upper quadrant pain. The patient underwent ultrasonography and revealed thickened and echogenic falciform ligament. Further, a computed tomography revealed swollen falciform ligament with associated fat stranding. The patient was kept under conservative management and improved over 2 weeks.

A Case Report of Falciform Ligament Appendagitis.

Falciform ligament appendagitis is an extremely rare form of intra-abdominal focal fat infarction. It usually presents with vigorous abdominal pain and mimics other more common acute abdominal pain-associated diseases. Better recognition of this entity avoids misdiagnoses and unnecessary surgical treatment. We present the case of a 73-year-old woman admitted to the emergency department for abdominal pain, nausea, and vomiting. She had a fever and a diffuse tender abdomen with upper right quadrant pain. Laboratory investigation showed leukocytosis and high C-reactive protein. CT revealed a heterogeneous increased density of fat adjacent to the falciform ligament. Falciform ligament appendagitis was diagnosed and antibiotic and anti-inflammatory treatment resulted in complete recovery. This case highlights the need to raise awareness and better recognize falciform ligament appendagitis to avoid unnecessary surgical interventions.

Falciform Ligament Infarction: A Case Report and Review of the Literature.

The falciform ligament is a double peritoneal fold that separates the left and right hepatic lobes anatomically. Fatty-falciform ligament appendage torsion (F-FLAT) is defined as torsion of the extraperitoneal fat within the falciform ligament causing fat infarction, which is an uncommon surgical presentation, scarcely documented within the current literature. The objective of presenting this case report and reviewing the literature on F-FLAT is to discuss the clinical presentation, possible associated factors and management strategies in regard to this rare pathology. A 72-year-old female patient presented to the emergency department with a seven-day history of epigastric pain, reduced appetite and nausea. On admission, the patient was stable and apyrexial with abdominal examination highlighting she was tender in her right upper quadrant and epigastric region. Due to the patient's unremitting abdominal pain despite appropriate analgesia, CT of the abdomen and pelvis (CTAP) with intravenous contrast was done and a diagnosis of F-FLAT was made. The patient was treated with antibiotics and analgesia, had a negative abdominal ultrasound (US) result and due to her symptoms settling by the second day of admission, she was discharged the same afternoon. A literature review into falciform ligament infarction was conducted by two independent reviewers across four different databases: PubMed, Medline, Embase and the Cochrane Library. Search terms included "falciform ligament" OR "falciform" AND "infarction" (likewise with Medical Subject Headings, or MeSH, terms in the Cochrane Library). Eligibility criteria and our subsequent inclusion criteria were based on studies specifically discussing falciform ligament infarction and published in English. Study types were by majority case reports, but also included one literature review and a book source as well as two pictorial radiological reviews. All 13 patients presented with abdominal pain, but only 53% presented with raised infective/inflammatory markers. The majority of patients had abdominal US as a first-line investigation with 9 of 13 patients also having a CTAP with contrast, which classically showed fat stranding in the falciform ligament. Two patients had no evidence of any radiological investigation. Initially all cases were managed conservatively with non-steroidal anti-inflammatory drugs and analgesia, but in 62% of the cases (8/13), surgical intervention was needed due to unresolving abdominal pain. All eight of the excised falciform ligaments showed evidence of infarction and necrosis histologically. In conclusion, F-FLAT is a relatively rare condition making it difficult to build higher level evidence studies. The current literature has revealed some evidence of incomplete and inconsistent data, for example, in the biochemical results and management techniques presented, yet contrast-enhanced CT seems moderately sensitive for detection in the reviewed literature. Though F-FLAT is rare and unfamiliar, it is vital we exclude common acute surgical pathologies that F-FLAT mimics and monitor for unsettling symptoms that could change the management trajectory.

Microsurgical strategies for small unruptured dorsal internal carotid artery aneurysms.

OBJECTIVE: This study aimed to develop microsurgical strategies based on the anatomical relationship between dorsal internal carotid artery (ICA) aneurysms, the falciform ligament (FL), and the anterior clinoid process (ACP). METHODS: Between 2017 and 2022, 25 patients with unruptured dorsal ICA aneurysms (less than 4 mm in diameter) underwent microsurgical direct clipping. These cases involved the left ICA (n=17) and the right ICA (n=8), with a mean aneurysm size of 3.3 mm (range, 2.5 to 4 mm). We used computed tomography angiography (CTA) and digital subtraction angiography to elucidate the anatomical relationship between dorsal ICA aneurysms and other structures. All procedures involved an ipsilateral pterional approach with securement of the ipsilateral cervical ICA for proximal control. RESULTS: Among the 25 dorsal ICA aneurysms, 8 (32%) were clipped without the FL being incised. Another 5 (20%) were clipped solely after the FL was cut. For the remaining 12 cases, the aneurysms were successfully clipped following FL incision and partial ACP removal. Patients exhibited favorable postoperative recoveries with good outcomes, and postoperative CTA revealed complete aneurysm clipping without any residual remnants. Conclusions: We were able to perform clipping without removing the ACP in 13 patients (52%), and in 8 of these (32%), the clipping was carried out directly without cutting the FL. Microsurgery, coupled with proximal control of the cervical ICA, can serve as a viable alternative for patients with small dorsal ICA aneurysms, especially when endovascular treatment options are limited, and 3D CTA confirms a clear anatomical relationship with the ACP.

A Case Report of a Rare Hernia: Incarcerated Falciform Ligament Hernia.

Falciform ligament hernias are a rare type of internal hernia that occurs through an abnormal opening in the falciform ligament of the liver. This is the case of a 38-year-old female who presented with a symptomatic enlarging ventral bulge near her umbilicus and was treated with a robotic-assisted laparoscopic falciform hernia repair with mesh. The nonspecific clinical manifestation of a falciform ligament hernia and the low sensitivity of computerized tomography (CT) for these hernias make them hard to diagnose preoperatively. Falciform ligament hernias are mostly attributed to congenital defects, but recently an iatrogenic etiology has also been proposed, given the prior history of laparoscopic surgeries in more recent cases. In our case report, we demonstrate that a robotic-assisted laparoscopic approach is a safe and effective means of correcting this hernia, with an outline of the current literature.

Falciform ligament hernia: combination of key CT findings.

A male patient in his early 90s with no history of abdominal surgery was referred to us for abdominal pain and vomiting. An abdominal computed tomography (CT) demonstrated dilated small bowel with a double beak sign and poorly enhanced wall, which indicated a closed-loop obstruction that leads to strangulation. A closed-loop bowel was located in front of the anterior and medial segments of the liver and to the right of the round ligament of the liver on axial images. Sagittal images revealed that the round ligament has deviated downward and 2 adjacent narrowed intestines were located at its cranial side. These CT findings suggested the hernia orifice was in the falciform ligament. Emergency surgery for highly suspected bowel ischemia revealed the falciform ligament hernia. A combination of the CT findings played a key role, including the double beak sign, the location of the closed-loop small bowel, and the downward deviation of the round ligament, although preoperative CT diagnosis of falciform ligament hernia is a diagnostic challenge.

Application of the Falciform Ligament Patch for the Prevention of Duodenal Stump Leakage After Gastrectomy: Technical Report on a Case Series.

Background: Duodenal stump leakage (DSL) is a serious complication after gastrectomy. In this study, we developed a novel prevention technique using a falciform ligament patch (FLP) to prevent DSL among high-risk patients after gastrectomy. Materials and Methods: From January 2019 to July 2021, 14 patients who were judged to be at high risk for DSL during preoperative examinations or surgery were included in this retrospective study, and the FLP was applied to the duodenal stump. The falciform ligament was separated from the liver after duodenal transection during gastrectomy; the end part was used to cover the duodenal stump and was fixed using nonabsorbable polypropylene sutures. Results: In total, 14 patients who underwent FLP had one or two risk factors that were identified: 5 patients, gastric cancer duodenal invasion; 4 patients, gastric outlet obstruction (GOO); 1 patient, cancer involving the distal resection margin; 1 patient, duodenal gastrointestinal stromal tumor involving the distal resection margin; 1 patient, gastric cancer duodenal invasion and GOO; and 2 patients, cancer involving the distal resection margin and GOO. FLP construction was successful, and no patient developed complications of DSL. The average hospital stay was 11.9 days, and the patients were discharged without any morbidities after surgery. Conclusions: Therefore, the FLP can be used to prevent DSL among high-risk patients after gastrectomy.

Utility of Falciform Ligament in Abdominal Surgery: A Systematic Review.

OBJECTIVE: The aim of the present systematic review was to assess current trends in use of falciform ligament in abdominal surgery. BACKGROUND: The falciform ligament has been proposed in surgical literature as a suitable pedicle or flap with acceptable surgical outcomes; however, it is underutilized in abdominal surgery. METHODS: We performed a literature search and meta-analysis. All English studies describing use of a falciform ligament were eligible for inclusion. RESULTS: Of the 547 articles mentioning use of falciform ligament, 32 full text articles were included in this review. The majority were case reports (n = 14). The mremaining papers included retrospective analysis (n = 10), randomized control trials (n = 2), reviews (n = 3), and technique descriptions (n = 6). CONCLUSION: The falciform ligament appears to be a safe and easily accessible natural tissue with a variety of surgical applications. It is most useful as a pedicle flap and could have benefit in foregut surgery including hepatic, pancreatic, biliary, gastric, and esophageal operations.

Uncommon presentation of complicated internal hernia through the appendices epiploicae ring of adhesion: a clinical case study.

Background: Internal hernias are infrequent, yet serious, medical conditions with potentially severe consequences. An internal hernia resulting from an Appendices epiploicae (AE) ring is an especially rare cause, with a mere nine documented instances worldwide. Case report: This report presents the case of a 58-year-old male who suffered from an internal hernia originating from an AE ring. The condition led to a gangrenous small bowel, which was treated by laparotomy and resection of the affected segment, followed by primary anastomosis. The post-operative recovery was favorable. Conclusion: Internal hernias, although rare, warrant immediate attention and early intervention to preclude detrimental outcomes, as illustrated in this particular case.

The Osteogenic Potential of Falciform Ligament-Derived Stromal Cells-A Comparative Analysis between Two Osteogenic Induction Programs.

Mesenchymal stromal cells (MSCs) have gained special relevance in bone tissue regenerative applications. MSCs have been isolated from different depots, with adipose tissue being acknowledged as one of the most convenient sources, given the wide availability, high cellular yield, and obtainability. Recently, the falciform ligament (FL) has been regarded as a potential depot for adipose tissue-derived stromal cells (FL-ADSCs) isolation. Nonetheless, the osteogenic capability of FL-ADSCs has not been previously characterized. Thus, the present study aimed the detailed characterization of FL-ADSCs' functionality upon osteogenic induction through a classic (dexamethasone-based-DEX) or an innovative strategy with retinoic acid (RA) in a comparative approach with ADSCs from a control visceral region. Cultures were characterized for cell proliferation, metabolic activity, cellular morphology, fluorescent cytoskeletal and mitochondrial organization, and osteogenic activity-gene expression analysis and cytochemical staining. FL-derived populations expressed significantly higher levels of osteogenic genes and cytochemical markers, particularly with DEX induction, as compared to control ADSCs that were more responsive to RA. FL-ADSCs were identified as a potential source for bone regenerative applications, given the heightened osteogenic functionality. Furthermore, data highlighted the importance of the selection of the most adequate osteogenic-inducing program concerning the specificities of the basal cell population.

Torsion of the fatty appendage of the falciform ligament.

Pathology of the falciform ligament is extremely rare. We present a case of a 50-year-old man with a torsion of the fatty appendage of the falciform ligament. This is a self-limiting disease. To prevent unnecessary surgical management, it is important to recognize on computed tomography scans.

Hepatic falciform ligament appendagitis evaluated by ultrasound: A report of 2 cases.

Falciform ligament appendagitis is an extremely rare disorder, which is characterized by hematogenous or nonhematogenous inflammatory changes in the fat appendage that is contiguous with the falciform ligament. The imaging and clinical features of this condition are similar to those of epiploic appendagitis, especially when caused by torsion of the fatty appendage (ie, falciform ligament appendage torsion). We report 2 cases of falciform ligament appendagitis with localized epigastric pain. The ultrasound imaging features of the 2 cases presented here were an oval hyperechoic mass contiguous with the falciform ligament and increased echogenicity of the surrounding inflammatory fat. Both patients were managed conservatively with symptomatic treatment alone. Understanding the imaging features of this falciform ligament appendagitis is important, because ultrasound is often the first choice for noninvasive imaging of acute abdomen. As there is limited detailed literature on falciform ligament appendagitis comparing high-frequency linear probes with CT and MRI, we consider this case report to add valuable information on this poorly reported condition.

Case report of falciform ligament abscess-The importance of early diagnosis.

Ligaments are peritoneal duplications that contain venous and lymphatic vessels that can potentially be pathways for the spread of infection. Primary inflammation of one of the peritoneal ligaments is very rare. Abscess of the falciform ligament (FLA) is a rare pathological substrate whose pathophysiology is still unknown or poorly understood, but most often occurs as a consequence of a local inflammatory process such as acute cholangitis, cholecystitis, pancreatitis or pylephlebitis. The diagnosis of the primary site of inflammation as well as FLA is established by radiological methods-ultrasound (US), computed tomography (CT) and magnetic resonance (MR), while the therapy is most often combined-conservative and surgical, but interventional radiology methods can also be used. In this report, we present a 67-year-old patient with the falciform ligament abscess that developed during epizode of acute cholecystitis with left portal vein thrombosis, which was diagnosed by US and CT and effectively managed with antibiotic treatment. FLA is a severe inflammatory condition that requires prompt diagnosis and aggressive antibiotic therapy to avoid surgical treatment.
