Trauma to the gallbladder is associated with concurrent injuries to the extra hepatic biliary system: A South African experience.

INTRODUCTION: Gallbladder trauma is a rare injury. This study aimed to describe the significance of these injuries and the appropriate management strategies. METHODS: A retrospective study was undertaken at a major trauma centre in South Africa and included all patients diagnosed with a gallbladder injury between January 2012 and October 2020. RESULTS: A total of 51 cases were included (88% male, mean age: 38 years), with 44 (86%) penetrating trauma cases [28 stab wounds (SW), 16 sustained gunshot wounds (GSW)]. Of the 7 (13%) blunt trauma cases, five were involved in a motor vehicle crash, and two were injured via assault. All patients underwent laparotomy. Full-thickness gallbladder laceration or perforation was the most common type of injury (84%) and all patients with a gallbladder perforation or laceration had a cholecystectomy at index operation. Two out of 5 patients with a gallbladder contusion were managed conservatively without a cholecystectomy and the remaining three had evidence of gallbladder necrosis which were managed with cholecystectomy. Associated extrahepatic bile duct injuries occurred in 4% of cases, and 18 cases (35%) required intensive care unit (ICU) admission. The overall mortality was 8%. CONCLUSION: Gallbladder injury is rare but when encountered implies a significant degree of trauma. Although cholecystectomy is usually definitive, there is an association with other occult extra-hepatic biliary tract injuries. The severity of the associated injuries usually determines patient outcomes.

Traumatic Gallbladder Perforation in Children - Case Report and Review.

BACKGROUND: Gallbladder perforation is a very rare finding in children. Clinical and radiografic presentations are often vague. Hence it is a challenging diagnosis, often missed during initial evaluation with potentially fatal consequences. The aim of this case report and review was to identify factors that might help to diagnose and manage future cases. METHODS: We present a case of gallbladder perforation in an 8-year-old child after blunt abdominal trauma caused by a handlebar in which imaging modalities such as ultrasound and magnetic resonance imaging (MRI) helped us to determine proper management. We identified and evaluated comparable cases for isolated traumatic gallbladder injury. A review of the recent literature was performed by online search in Pubmed and Google Scholar using "gallbladder injury in children", "gallbladder perforation children", "blunt abdominal trauma children" as keywords. We focused on articles exclusively in the pediatric section. The literature from the period 2000-2020 was taken into account to review the state of the art in diagnosis and management. RESULTS AND CONCLUSION: Recent literature for gallbladder injury in pediatrics is sparse compared to the adult counterpart. Only eight published cases of isolated gallbladder injury in children were identified. Since the onset of symptoms may not develop acutely and often develops in an indistinct manner, radiografic examinations play an important role in the diagnostic progress. The authors advise caution in cases of blunt abdominal trauma especially involving handlebars, intraperitoneal free fluid, and severe abdominal pain. We advocate high suspicion of gallbladder perforation if the gallbladder wall displays discontinuation or cannot be definitively differentiated in sonografic examination. Echogenic fluid within the gallbladder should always lead to suspicion of intraluminal bleeding. Repeated clinical and imaging examinations are mandatory since the onset of signs and symptoms may be delayed. KEY POINTS: · Awareness of gallbladder perforation in blunt abdominal trauma of the upper abdomen.. · Particularly high index of suspicion in cases involving handlebar injuries.. · Repeated clinical and imaging examinations are highly recommended..

The Dutch-Belgian Registry of Stereotactic Body Radiation Therapy for Liver Metastases: Clinical Outcomes of 515 Patients and 668 Metastases.

PURPOSE: Although various studies have reported that stereotactic body radiation therapy (SBRT) for liver metastases has high local control rates and relatively low toxicity, most series included a small number of patients. We aimed to validate these outcomes in a large multi-institution patient cohort treated in accordance with a common protocol. METHODS AND MATERIALS: A shared web-based registry of patients with liver metastases treated with SBRT was developed by 13 centers (12 in the Netherlands and 1 in Belgium). All the centers had previously agreed on the items to be collected, the fractionation schemes, and the organs-at-risk constraints to be applied. Follow-up was performed at the discretion of the centers. Patient, tumor, and treatment characteristics were entered in the registry. Only liver metastases treated individually as independent targets and with at least 1 radiologic follow-up examination were considered for local control analysis. Toxicity of grade 3 or greater was scored according to the Common Terminology Criteria of Adverse Events (v4.03). RESULTS: Between January 1, 2013, and July 31, 2019, a total of 515 patients were entered in the web-based registry. The median age was 71 years. In total, 668 liver metastases were registered, and 447 were included for local control analysis. The most common primary tumor origin was colorectal cancer (80.3%), followed by lung cancer (8.9%) and breast cancer (4%). The most-used fractionation scheme was 3x18-20 Gy (36.0%), followed by 8x7.5 Gy (31.8%), 5x11-12 Gy (25.5%), and 12x5 Gy (6.7%). The median follow-up time was 1.1 years for local control and 2.3 years for survival. Actuarial 1-year local control was 87%; 1-year overall survival was 84%. Toxicity of grade 3 or greater was found in 3.9% of the patients. CONCLUSIONS: This multi-institutional study confirms the high rates of local control and limited toxicity in a large patient cohort. Stereotactic body radiation therapy should be considered a valuable part of the multidisciplinary approach to treating liver metastases.

Laparoscopic Ultrasound and Safe Navigation Around the Shrunken Gallbladder.

Background: The contracted gallbladder may predispose to a higher rate of biliary or vasculobiliary injury (VBI). It is usually associated with unclear anatomy due to chronic inflammation and fibrosis in the hepatoduodenal ligament region. Laparoscopic ultrasound (LUS) can very effectively delineate anatomical conditions during cholecystectomy. Our study aimed to compare the visual and ultrasonographic navigation around the shrunken gallbladder. Materials and Methods: The study group consisted of 612 patients qualified for laparoscopic cholecystectomy. The shrunken gallbladder was diagnosed intraoperatively in 13 patients (2.1%). In 6 patients, the only intraoperative navigation method was a visual evaluation of anatomical conditions, and in 7 patients, the method was LUS. Results: The operating time and the length of hospital stay after surgery were significantly lower, the number of conversions was insignificantly lower, and the number of successful visualization of anatomical conditions was significantly higher in the LUS group. We did not observe any bile duct and VBI in patients with the shrunken gallbladder. Conclusions: The combination of the fundus-first and subtotal cholecystectomy with LUS navigation might be an effective proposal when coming across the shrunken gallbladder.

What Should be Done for Perforation of the Gallbladder During Laparoscopic Cholecystectomy: Prophylaxis or Treatment?

Background: Iatrogenic perforation of the gallbladder during laparoscopic cholecystectomy (LC) is one of the most common intraoperative complications, and there is no clear consensus among surgeons on this issue and there are studies reporting the antibiotic treatment. The aim of this study is to determine the effect of type and duration of antibiotic use on infective complications between iatrogenic perforations of the gallbladder during LC patients. Methods: Patients who developed iatrogenic perforation of gallbladder during LC were subdivided into three groups according to antibiotic treatment; single dose intravenous (i.v.) antibiotic group, prophylactic antibiotic + additional dose i.v. antibiotic group, and prophylaxis + additional dose i.v. antibiotic + oral antibiotic group. Results: A total of 577 patients who underwent LC were included in the study, and 114 patients (19.8%) had iatrogenic perforation of gallbladder. No statistically significant difference was found in wound infection and surgical site infection in all three groups (P > .05). Conclusions: We suggest that single dose antibiotic use is sufficient to prevent infectious complications in patients who had iatrogenic perforation of the gallbladder during LC. Adding intravenous and/or oral antibiotics does not contribute to prevention of infective complications in these patients.

Acute hemorrhagic cholecystitis with gallbladder rupture and massive intra-abdominal hemorrhage

Acute hemorrhagic cholecystitis is a rare, life-threatening condition that can be further complicated by perforation of the gallbladder. We describe a patient with clinical and radiologic findings of acute cholecystitis with a gallbladder rupture and massive intra-abdominal bleeding. Our patient is a 67-year-old male who presented with an ischemic stroke and was treated with early tissue plasminogen activator. His hospital course was complicated by a fall requiring posterior spinal fusion surgery. He recovered well, but several days later developed subxiphoid and right upper quadrant pain and an episode of hemobilia and melena. A computed tomography scan revealed an inflamed, distended gallbladder with indistinct margins and a large hematoma in the gallbladder fossa extending to the right paracolic gutter. The patient also developed hemodynamic instability concerning for hemorrhagic shock. He underwent an emergent laparoscopic converted to open subtotal fenestrating cholecystectomy with abdominal washout for management of his acute hemorrhagic cholecystitis with massive intra-abdominal hemorrhage. Prompt recognition of this lethal condition in high-risk patients is crucial for optimizing patient care.

A Case Report of Isolated Blunt Traumatic Gallbladder Perforation and Review of the Literature.

INTRODUCTION: Gallbladder trauma is an uncommon occurrence, most commonly found incidentally at the time of laparotomy for associated injuries following abdominal trauma. It is even more rare in blunt abdominal trauma, with one of the rarest forms being an isolated injury to the gallbladder. Awareness for this type of injury should not be forgotten by emergency personal when evaluating someone with a history of recent trauma. CASE DESCRIPTION: A 44-year-old male who works as a construction worker fell from a roof, landing on his right side. Upon evaluation by the emergency department, emergency personnel combined the history, abnormal laboratory values and imaging including ultrasound (U/S) and computed tomography (CT) to assess and diagnose a concern for gallbladder perforation. He was treated with a diagnostic laparoscopy, laparoscopic cholecystectomy, and intraoperative choleangiogram. The patient tolerated the procedure well and discharged home on postoperative day 1. DISCUSSION: Gallbladder trauma can be seen in all population types. As the gallbladder is fairly protected, it is rare to have an isolated injury. A detailed history as described can tip off practitioners to the diagnosis, but is also missed or delayed due to occasionally vague symptoms. Imaging studies can be used adjunctively to assist in diagnosis and may include CT, U/S, color Doppler, or HIDA scans. These can also fail to give a diagnosis leading to a missed injury and further morbidity and mortality. Perforated gallbladders can safely be treated laparoscopically as well as other options depicted. CONCLUSION: Awareness of isolated and rare injuries in trauma, such as those to the gallbladder, enables many types of emergency personnel to recognize and treat patients and consequently prevent the morbidity and mortality of a missed injury.

Accuracy of Preoperative MDCT in Patients With Penetrating Abdominal and Pelvic Trauma.

PURPOSE: This study aims to evaluate the overall diagnostic accuracy of preoperative multidetector computed tomography (MDCT) in penetrating abdominal and pelvic injuries (PAPI). METHOD AND MATERIALS: We used our hospitals' trauma registry to retrospectively identify patients with PAPI from January 1, 2006, to December 31, 2016. Only patients who had a 64-MDCT scan at presentation and subsequently underwent laparotomy or laparoscopy were included in our study cohort. Each finding noted on MDCT was rated using a 5-point scale to indicate certainty of injury, with a score of 0 being definitive. Using surgical findings as the gold standard, the accuracy of radiology reports was analyzed in 2 ways. A κ statistic was calculated to evaluate each pair of values for absolute agreement, and ratings for all organ systems were analyzed using a repeated measures analysis of variance (ANOVA) to determine whether radiology and surgical findings were similar enough to be clinically meaningful. Qualitative review of the radiology and surgical reports focused on the gastrointestinal (GI) tract was conducted. RESULTS: Our cohort consisted of 38 males and 4 females with a median age of 29 years and a median injury severity score of 15.6. For this study, 12 different organ groups were categorized and analyzed. Of those organ groups, absolute agreement between MDCT and surgical findings was found only for liver and spleen (κ values ranging from 0.2 to 0.5). Additionally, the ANOVA revealed an interaction between finding type and organ system (F 1, 33 = 7.4, P < .001). The most clinically significant discrepancies between MDCT and surgical findings were for gallbladder, bowel, mesenteric, and diaphragmatic injuries. Qualitative review of the GI tract revealed that radiologists can detect significant findings such as presence of injury, however, localization and extent of injury pose a challenge. CONCLUSION: The detection of clinically significant injuries to solid organs in trauma patients with PAPI on 64-MDCT is adequate. However, detection of injury to the remaining organ groups on MDCT, especially bowel, mesentery, and diaphragm, remains a challenge.

Introduction Gallbladder injury secondary to blunt abdominal trauma is a rare event. Aim Review the current available scientific literature and describe a case. Materials and Method Using the PubMed platform, the following keywords were searched: "Blunt abdominal trauma". Series with gallbladder lesions were selected: "Traumatic gallbladder rupture". Reports of isolated lesions of the gallbladder were selected: "Isolated gallbladder rupture". Reports of late presentation of isolated lesions of the gallbladder were selected: "Delayed presentation of isolated gallbladder rupture". Of all these publications, those that were relevant to the present case were selected according to the criteria of the authors. Case report A 20 years-old male patient suffered an abdominal trauma two weeks before presentation at our Institution. He underwent an exploratory laparotomy showing bilious content and a gallbladder perforation over the peritoneal wall as an isolated injury. Discussion Most isolated gallbladder perforations occur in healthy gallbladders with thin walls and distended because fasting or alcohol consumption. There are no classical clinical features to diagnose this specific injury and radiologic studies are nonspecific. Definitive diagnosis is often reached during surgery as it was with our patient. Recommended treatment is cholecystectomy. Conclusions This case illustrates this unique kind of gallbladder injury in patients with blunt abdominal trauma. A clear diagnosis is not easy however, the treatment is simple and prognosis is good.

Isolated gallbladder injury from blunt abdominal trauma: A rare co-incidence.

Gallbladder injury resulting from blunt abdominal trauma is a rare entity and generally associated with other intra-abdominal injuries. Incidence of isolated gallbladder injury has not been reported yet. The most common mechanism of injury reported is road traffic accident. Diagnosis is usually made on imaging as clinical presentation may vary from no symptoms to peritonitis due to extravasation of bile in the abdominal cavity. Cholecystectomy is the treatment of choice and minimally invasive approach can be considered in haemodynamically stable patients.

Intraoperative bile spillage is associated with worse survival in gallbladder adenocarcinoma.

BACKGROUND: Gallbladder adenocarcinoma is often incidentally identified following cholecystectomy. We hypothesized that intraoperative bile spillage would be a negative prognostic factor. METHODS: A retrospective review of patients treated at a cancer center with histologically confirmed gallbladder adenocarcinoma, 2009-2017, was performed. Patient, disease, and treatment factors were analyzed in terms of progression-free survival (PFS) and overall survival (OS). RESULTS: Sixty-six patients were identified. Tumor stage was T1 (n = 8, 12%), T2 (n = 23, 35%), T3 (n = 35, 53%). Node stage was N0 (n = 22, 33%), N1+ (n = 26, 39%), Nx (n = 18, 27%). Operations included cholecystectomy alone (n = 27, 36%), cholecystectomy and partial hepatectomy (n = 30, 45%), or hepaticojejunostomy (n = 9, 14%). Median PFS was 7 months (interquartile range [IQR], 2-19); median OS was 16 months (IQR, 10-31). Subset multivariate proportional hazards regression of 41 patients who underwent initial cholecystectomy showed decreased PFS was associated with intraoperative spillage (n = 12, 29%; hazard ratio [HR], 5.5; P = .0014); decreased OS was associated with drain placement (n = 21, 51%; HR, 8.1; P = .006). CONCLUSIONS: Intraoperative bile spillage and surgical drain placement at initial cholecystectomy are negatively associated with PFS and OS in gallbladder adenocarcinoma. Explicit documentation of spillage and drain placement rationale is critical, possibly indicating locally advanced disease and prompting stronger consideration of systemic therapy before definitive resection.

10-mm Laparo-Endoscopic Single-Site Cholecystectomy Using Multiple Magnetically Anchored and Controlled Instruments.

BACKGROUND: To study the feasibility of laparo-endoscopic single-site (LESS) cholecystectomy through a 10-mm incision using a miniature magnetically anchored and controlled laparoscopy system and a grasper system. METHODS: The miniature magnetically anchored and controlled laparoscopy system consisted of a miniature magnetically anchored camera (MMAC), an external magnetic anchoring unit, and a vision output device. The camera weighed 9.8 g and measured Φ10 mm × 50 mm. The magnetically anchored and controlled grasper system consisted of a magnetically anchored grasper (MAG), an external magnetic anchoring unit, and a push-pull device. The MAG had a titanium alloy clip head and a magnetic tail. The laparoscopy system and grasper system were used simultaneously to perform LESS cholecystectomy through a single 10-mm incision in model canines. RESULTS: LESS cholecystectomy through a 10-mm incision using the MMAC and MAG was attempted in six dogs. The mean operative time was 85.75 ± 7.14 min. The operation was completed successfully in four cases, with failure occurring in one case due to gallbladder rupture and in another due to bile duct injury. The MMAC provided clear imaging, and the MAG provided sufficient exposure to perform the cholecystectomy. The use of multiple magnetically anchored and controlled instruments did not result in notable collisions. CONCLUSIONS: The designed MMAC and MAG system could be easily maneuvered. LESS cholecystectomy may be feasible through a single 10-mm incision with the simultaneous use of multiple magnetically anchored and controlled instruments.

In vivo 1 H MRS of human gallbladder bile in understanding the pathophysiology of primary sclerosing cholangitis (PSC): Immune-mediated disease versus bile acid-induced injury.

Primary sclerosing cholangitis (PSC) has been considered to be either an "autoimmune disease" or a "bile acid-induced injury." In vitro MRS studies on PSC patients have limitations due to the contamination of bile with contrast agent (commonly administered during endoscopic retrograde cholangiopancreatography) and/or the use of patient cohorts with other diseases as controls. The objective of this study was to quantify biliary metabolites using in vivo 1 H MRS and gain insight into the pathogenesis of PSC. Biliary metabolites in 10 PSC patients and 14 healthy controls were quantified in vivo using 1 H MRS on a 3 T MR scanner. The concentrations of total bile acids plus cholesterol, glycine-conjugated bile acids, taurine-conjugated bile acids, and choline-containing phospholipids (chol-PLs) were compared between the two groups. There were statistically significant decreases in the levels of the above mentioned biliary metabolites in the PSC patients compared with controls. The reduction in bile acid secretion in bile of PSC patients indicates accumulation of bile acids in hepatocytes. Moreover, reduction in the levels of chol-PLs in bile may increase the toxic effects of bile acids. Our findings suggest that the bile duct injury in PSC patients is most likely due to "bile acid-induced injury."

Mechanical strength of biliary defect closure after topical sealing: Comparison of four sealants in a porcine model.

BACKGROUND/OBJECTIVE: Biliary leakage is a potential complication of liver resection and is still a concern. The aim of the present study was to evaluate the effectiveness of four routinely used sealants in preventing bile leakage under pressure from an induced perforation of the gallbladder in a porcine model. METHODS: Forty Landrace pigs were randomly assigned to one of five groups. These included a control group (n = 8) and one group each for the sealants TachoSil®, TissuCol Duo®, Coseal®, and FloSeal® (n = 8 per group). In the control group, the perforation was left unsealed. To evaluate the biliostatic potential of the sealants, we measured the pressure that was needed to induce leakage (mmHg) and the gallbladder volume (cc) at the time of leakage in each group. RESULTS: A significantly higher mean pressure was required to induce leakage in the sealant groups compared with the control group. However, the biliostatic effects were heterogeneous among the sealant groups. Sealants with the highest to lowest effectiveness were TachoSil, Coseal, TissuCol, and FloSeal. The mean gallbladder volume at the time of leakage also varied between sealant groups. CONCLUSION: Biliostatic properties are markedly improved by the use of modern sealants compared with using no sealant. However, the advantages and disadvantages of using sealants should be carefully considered in each clinical situation. The effectiveness of the sealants should be evaluated in chronic and clinical studies.
