“…Importantly, Judd et al first documented “autoamputation of the appendix” in 1915 [ 1 ], followed by Wejsflog et al [ 7 ], Iasocki et al [ 8 ] and Volnohradský et al [ 9 ], but no full text of the above articles were available. Sachs et al reported a case of mucocele occupying the entire appendix, with laparoscopic findings of appendix autoamputated from the root [ 10 ]; Iuchtman et al reported a total of 5 cases of appendiceal autoamputation over 30 years (1961–1991), no detailed description was provided [ 11 ]. Halvey et al reported a 20-day-old male infant with a strangulated and gangrenous appendix within the right inguinal hernial sac, with a severe inflammatory reaction that led to autoamputation of two-thirds of the appendix [ 12 ].…”

Autoamputation of the appendix and survival of the amputated part: a rare case report and literature review

et al. 2022

Background Autoamputation of the appendix, i.e., complete separation of a part of the appendix without any surgical intervention, has been rarely documented in the literature in recent years. Herein, we report a case where the amputated part of the appendix was viable after autoamputation and reviewed the related literature. Case presentation A 39-year-old female patient was admitted to our hospital complaining of abdominal pain and subsequently underwent an emergency laparoscopic appendectomy (LA). Intraoperatively, we found an abnormally short appendix protruding from the cecum and a strip-like tissue attached to the mesoappendix, considered a duplex appendix, was resected. Finally, in conjunction with the histopathology findings and the past medical history, the patient was diagnosed with “Pseudo-duplication of the Appendix”. Conclusions Autoamputation of the appendix resulting in preserved tissue viability and absence of necrosis at both ends, can be termed as “Pseudo-duplication of the Appendix”. This condition is very rare in clinical practice and has not been reported in China, to the best of our knowledge. It has been established that the autoamputated appendix can produce chronic inflammation, intestinal fistulae and even cancer, affecting the patient’s quality of life. Accordingly, a clear diagnosis and timely management are essential. In this report, we established a novel classification for “Pseudo-duplication of the Appendix”, hoping that our report will help surgeons better understand this anatomical anomaly of the appendix, to help during the differential diagnosis process and avoid confusion.

“…Although appendiceal endometriosis is reported many times within literature, reports of autoamputation of the appendix are rare. A case of autoamputation of a mucocele of the appendix was described in 1951 [ 2 ]. The mucocele was described as occupying the entire appendix, which had self-amputated from the cecum.…”

Autoamputation of the Appendix in a Chronic Adnexal Abscess

Autoamputation of the appendix has rarely been described in the literature. We present a case of a pelvic mass, thought to be a dermoid cyst based on preoperative imaging. After surgical removal and pathological examination, the mass was found to be a chronic pelvic abscess containing the right adnexa as well as an autoamputated vermiform appendix. Differentiating between gynecologic and gastrointestinal disease preoperatively can be difficult and often a definitive diagnosis cannot be made until surgical exploration and pathological review. However, to our knowledge, this is the first described case of a chronic pelvic abscess containing an autoamputated vermiform appendix.

“…Autoamputation of the appendix is an unusual but welldocumented phenomenon. [1][2][3][4][5][6] Previous reports have speculated that a prior episode of appendicitis is most often the likely explanation for the finding. Interestingly, one instance of appendiceal autoamputation was described in the context of an incarcerated right inguinal hernia.…”

Autoamputation of the Appendix Presenting as a Calcified Abdominal Mass Following Necrotizing Enterocolitis

et al. 2017

Autoamputation of the appendix has previously been reported in the literature, but it is likely an unusual event. We report a 2-year-old male child who had previously undergone laparotomy and bowel resection for necrotizing enterocolitis. Two years later a calcified intra-abdominal mass was identified on abdominal radiography and ultrasonography. Eventual laparotomy revealed a densely calcified mass within the transverse mesocolon. The mass was uneventfully resected. Pathologic evaluation showed appendiceal tissue, consistent with prior autoamputation of the vermiform appendix. Autoamputation of the appendix has not to our knowledge previously been associated with a calcified mass nor been associated with a history of necrotizing enterocolitis, and these factors distinguish this case as noteworthy.
