“…Nevertheless, birds generally show mild clinical signs when they are ill, since the lack of physical fitness in groups can lead to loss of social position or make them vulnerable to predators [14]. Foreign bodies are usually metallic and can lodge in any segment of the gastrointestinal tract, commonly found in the proventricle and gizzard [5].

Background: The ingestion of foreign bodies in parrots has already been described and associated with the curious behavior of the birds or with stressful conditions. Foreign bodies in the gastrointestinal tract are usually diagnosed through clinical signs, laboratory tests, and radiographic findings in the historical data. Foreign bodies are usually metallic and can lodge in any segment of the gastrointestinal tract, commonly found in the proventricle and gizzard. This study investigated a case of necrotizing hepatitis due to a foreign body in Ara ararauna (Linnaeus, 1758).Case: An approximately 9-month-old specimen of caninde macaw, had sudden death and was referred for autopsy. The macroscopic examination revealed a fibrous, thick, reddish membrane involving the left hepatic lobe and partially the gizzard in continuity with the peritoneum. Inside the capsule, the liver had a friable and necrotic appearance and the gizzard had a focal perforation area containing a foreign body (gavage probe). We performed the histopathological examination of the liver and gizzard and observed that the membrane surrounding the liver and partially the gizzard had a chronic inflammatory process with a marked proliferation of fibrous tissue and fibrin deposition. The hepatic parenchyma of the left lobe showed diffuse and marked necrosis, with signs of ischemic necrosis. In the region of transmural perforation of the gizzard, the mucosa showed a focal area of extensive necrosis accompanied by the presence of intralesional bacteria. The lesions observed are attributed to the perforation of the organs by the foreign body. It is not known whether the bird ingested the object accidently during food handling as a young or due to the curious behavior of the bird or even the stress it may have been exposed to. The post-mortem examination revealed localized peritonitis and encapsulating necrotizing hepatitis, focally extensive and accentuated, associated with foreign body perforation.Discussion: The curious habit of parrots, can provide the ingestion of foreign bodies, in which they lodge in the gastrointestinal tract. Generally, the clinical signs are nonspecific, however, proventricular impaction, stasis and even perforations in the mucosa of organs can be observed. In the present study, we suspect that the Caninde macaw accidentally ingested a gavage probe during feeding management as a young. This object lodged in the bird's ventricle, perforating the organ and reaching the liver, due to intimate contact with the gizzard, providing a picture of ventriculitis and necrotizing hepatitis. Necrotizing hepatitis due to foreign body has been reported in the literature due to ingestion of perforating foreign body with lesion in the left ventricle and lobe, however we have no knowledge of reports with the presence of a capsule involving the left hepatic lobe, similar to a capsule like this, we understand that our report is the first description of encapsulating necrotizing hepatitis in birds. We believe that this capsule of connective tissue was formed, due to the inflammatory process in the peritoneal cavity, in birds the deposition of fibrin can form a structure similar to a capsule, in order to trap cells and the agent responsible for inflammation, preventing septicemia. Transmural perforation in the gizzard, observed in this case, allowed bacterial translocation that may have contributed to the worsening of the chronic condition and death due to the accumulation of toxins or bacterial translocation of the gastric tract, leading to liver infection and sepsis. We concluded that the presence of the perforating foreign body was responsible for the peritonitis and encapsulating necrotizing hepatitis in Ara ararauna.

“…In some cases, a caudoventral ventriculotomy through the thin muscle fibres can be used to enter the ventriculus (Guzman, 2016). In the case of ventriculotomy in a common myna, Champour and Ojrati (2014) had to approach the last two ribs to access the proventriculus, which requires a postoperative analgesic treatment (non-steroidal anti-inflammatory agents, NSAID). Most of these agents increase healing time and cause gastric ulceration and sluggish ulcer healing, especially in the acidsecreting portion of the gastrointestinal tract (Champour and Ojrati, 2014).…”

In the case of coeliotomy for the removal of a proventricular foreign body, some authors preferred ventriculotomy over proventriculotomy, which is also a possibility for removing a foreign body from the proventriculus in a bird (Goulart et al, 2019).…”

Removal of foreign bodies from the proventriculus in a young golden eagle (Aquila chrysaetos)

This paper presents a clinical case report of a golden eagle (Aquila chrysaetos) with foreign bodies (stones) in its proventriculus. The case deals with the identification, management and removal of foreign objects identified in the gastrointestinal tract. A surgical removal by proventriculotomy under general anaesthesia was attempted. The surgery and the recovery were uneventful, and the follow-up after six months revealed no complications. To the best of our knowledge, there are no other reports of successful foreign body removal by proventriculotomy in the golden eagle.

“…Gastrointestinal (GI) foreign bodies (FBs) have been reported in diverse avian species, especially in pet and captive birds. Commonly encountered FBs include items such as feeding tubes [1], wooden perches [2], wire [3,4], and fibrous materials, such as tent-like huts [5] and artificial grass fibers [6].…”

Various Endoscopic Approaches for Removal of Proventricular Foreign Bodies in Parrots—Three Case Reports

Although the use of incision-free endoscopy for foreign body (FB) removal in dogs and cats has been extensively documented, its application in birds remains limited. Thus, we present the endoscopic removal of gastrointestinal (GI) FBs from psittacine birds, employing different patient positioning and anesthesia methods. Two blue-and-yellow macaws (Ara ararauna) and a Triton cockatoo (Cacatua galerita triton) were examined. X-ray imaging revealed FBs situated in the proventriculus in each case. The FBs, all identified as feeding tubes, were safely removed using grasping forceps during the endoscopic procedure, and no severe complications occurred. Based on the outcomes of each operation, the most suitable patient position may be ventral recumbency rather than dorsal recumbency, with the use of a mask or endotracheal intubation, depending on the anticipated operation time. However, a larger number of cases would be necessary to confirm the optimal patient positioning and anesthesia method.
