Lesions of the gallbladder are rare [1]. They are the results of direct hits, shear acceleration/deceleration or more commonly penetrating wounds [2]. The lesion’s types are classified as contusion, perforation and avulsions [3]. Diagnosis of vesicular perforation is a challenge for the clinician. There is often a delay in clinical presentation with non-specific symptoms. Diagnostic imaging becomes a valuable tool for the rapid identification of gallbladder injury [4]. Although other therapeutic approaches are described, cholecystectomy is the optimal treatment [5].

Our purpose is to present through a clinical description of a post-traumatic gallbladder injury, its physio-pathological and evolutionary aspects.

14-year-old boy: a victim of abdominal trauma following a stabbing attack. Hospitalized initially at a peripheral hospital where he received primary care. It is received 2 days after trauma with normal vitals parameters. Clinically, the examination was marked by a right base-thoracic wound of 3 cm, a distended sensitive abdomen (epigastrium the right hypochondrium and the flanks). An abdominal ultrasound found a hepatic contusion (left lobe) associated with haemoperitoneum, the gallbladder seems normal but it contains echogenic sediment, probably hemobilia (Figure 1). The angio scan showed an abundant haemoperitoneum with a peri vesicular hematoma, and hepatic contusion (segment IV).

He benefited from a biological assessment (Table 1), prophylaxis antibiotic, blood transfusion; clinical biology and radiology monitoring. He was discharged on the 5th day after clinical stabilization. It is readmitted at D + 8 of the trauma for haematic fluid with lumps of pus through the para-gastric wound. Biological assessment (Table 1) was performed. Abdominal ultrasound: liver was normal, respect of portal and biliary structures, intraperitoneal effusion with finely echogenic content.

Peritoneal fluid sampling study showed: hematic color with 300,000 red blood cells and 20,000 white blood cells including 77% PNN, with E. coli to culture. Antibiotic has been adapted to the anti-biogramme.

He benefited from a cystoscopy which revealed a significant inflammation of the digestive tract with the presence of numerous false membranes on the underside limiting the exploration, locating the point of introduction of the knife

which sits at the level of the upper face liver. At D + 12, cholecystectomy was performed by laparotomy. We found a compartmentalized pelvic effusion (biliary peritonitis), a significant inflammation of the digestive tract with several adhesions, and a hepatic transvesiculo-cutaneous fistula (Figure 2). The postoperative evolution was simple, removal of the slides at D + 4 and discharged at D + 7 postoperative after improvement.

At the 6th month, he presented an acute intestinal obstruction on bridles, managed at emergency by open surgery. Release of the flanges is between the 6th and 9th intestinal loop.

After one year of follow up, the patient has no symptoms.

Post-traumatic vesicular lesions are rare, accounting for 1.9% of all abdominal trauma. This rarity is probably related to the protection of the organ by its visceral relations and the rib cage [1] [2] [4]. Often in association with the involvement of other organs including the liver in 83% to 91% and 54% for duodenal and spleen disorders [5].

The clinical presentation and symptoms of gallbladder perforation are monopolized by the associated lesions. Isolated, perforation of the gall bladder is often of delayed presentation with vague symptoms [6]. In many cases, the first symptoms are mild, consisting of abdominal discomfort and diarrhea. Biliary peritonitis may be present initially. A remission period variable is described before sudden deterioration [6]. Oumar Ndour et al. [7] reported the case of a

15-year-old adolescent admitted with peritoneal syndrome three weeks after blunt trauma to the abdomen. The diagnosis of vesicular perforation was made by laparotomy.

After a period of hemorrhage our patient presented a good clinical remission before being readmitted 72 hours in clinical and biological deterioration.

Biological analyses are not contributory to either positive diagnosis or differential diagnosis. Sanguine numerous formula will be late in hematoma-related blood spoliation, but useful in monitoring hemorrhage [8].

Disturbances in the hepatic function do not automatically have a direct hepatic lesion significance, but may be indirect in cases of extra-hepatic biliary disease but with hepatic impact [8].

In the traumatic context, observable disturbances have no diagnostic or prognostic value. If we can expect a very disturbed liver assessment in case of serious injury, they do not make the prognosis either. One should not rely on the normality of a liver test in a low suspicion of traumatic hepatic injury to eliminate this lesion; also valid for a lesion of the bile ducts [8].

Our patient was referred for a post-traumatic hemorrhage, clinically stable on examination which justifies our choice to perform a first-line angio-scanner. However, it only identified perivascular hematoma. The diagnosis of perforation was per operative. And according to the classification of Losanoff and Kjossev [9], our patient is classified as type 2.

Ultrasound is the cornerstone of the initial evaluation of the poly traumatized for the abdominal and thoracic part. The bile ducts are poorly visualizable and one cannot eliminate a biliary lesion by focus assessment ultrasound for trauma, nor even correctly suspect it [10].

CT scan is the reference examination to visualize the heamoperitoneum and the associated hepatic and/or biliary lesion (irregular gallbladder or hematoma in the lumen of the gallbladder). The contusion is probably the most common lesion but the least reported often diagnosed per operative. Perforation is the most commonly reported lesion. Avulsions are the rarest lesions; only eight cases of isolated complete avulsion have been reported [10].

Laparoscopy’s main interest is diagnosis, by confirming an heamoperitoneum, a digestive effusion, a diaphragmatic wound, and by allowing to affirm the penetrating character or not of a wound. It avoids an abusive laparotomy in 2/3 of the cases. In the case of a penetrating wound, it will be necessary to be aware of its limits (poor performance for the detection of digestive perforations) and do not hesitate to convert to laparotomy in the case of active bleeding or important peritoneal hematoma masking complete exploration, impossibility to explore the entire digestive tract [11].

In our context, laparoscopy exploration was limited by the abundant peritoneal hematoma but also by an important inflammation of the digestive tract with the presence of numerous false membranes on the inferior surface of the liver.

Perforation of the gallbladder is often treated by laparotomy. The surgeon must then look for the involvement of other organs [12]. Cholecystectomy is the optimal treatment [5].

The cholecystorraphy of penetrating lesions has been described, but this procedure presents risks such as a loss of repair and subsequent biliary leakage. In addition, even resorbable sutures placed in the vesicular wall may form a nest for subsequent formation of stones [12].

Cholecystectomy by laparoscopy has been described as the treatment of isolated perforation of the gallbladder due to abdominal injury [13]. However, the laparoscopy approach has certain limitations and is generally not recommended in the case of gallbladder injury, in which other concomitant lesions should be excluded. Although the laparoscope can give a good superficial view of the peritoneal cavity and excellent diaphragmatic view, inspection of the duodenum, pancreas and left hepatitis is not enough in the hands of most general surgeons without experience advanced laparoscopy [13].

Post-traumatic lesions of the gall bladder are rare, the vague clinical presentation and limited imaging tests in some forms make early diagnosis a real challenge for the clinician. Cholecystectomy remains the optimal treatment despite recent proposals for conservative treatment.
