Adyuvancia en tratamiento quirúrgico de fibroma osificante. A propósito de un caso / Adjuvance in surgical treatment of ossifying fibroma. Case report

El fibroma osificante es una neoplasia osteogénica benigna que representa el 3.1% de los tumores orales y el 9.6% de las lesiones gingivales. Su tratamiento de elección es la enucleación por curetaje completado hasta márgenes de hueso sano, con una recurrencia de aproximadamente el 7-20% probablemente por remoción incompleta, irritación continua o daño repetido. Presentamos un caso clínico en el que complementamos el tratamiento quirúrgico con métodos adyuvantes para disminuir la recurrencia y acelerar la regeneración ósea mediante uso de nitrógeno líquido y hueso liofilizado cadavérico combinados con plasma rico en plaquetas. En el control postoperatorio a los 6 meses no evidenciamos recurrencia clínica o radiológica y comprobamos regeneración ósea acelerada. Sugerimos el uso en este tipo de lesiones de nitrógeno líquido como adyuvante para la prevención de recurrencia, hueso liofilizado para favorecer la regeneración ósea guiada y plasma rico en plaquetas para acelerar el proceso de curación ósea

Ossifying fibroma is a benign osteogenic neoplasm, representing 3.1% of oral tumors and 9.6% of gingival lesions. Enucleation by curettage is the treatment of choice, completed to healthy bone margins, with a recurrence of approximately 7-20%, probably due to incomplete removal, continued irritation or repeated damage. We describe a clinical case ttreated in combination with adjuvant methods to decrease recurrence and accelerate bone regeneration, with the placement of liquid nitrogen and cadaveric lyophilized bone, combined with platelet-rich plasma. Post-operative control at 6 months showed no clinical or radiological evidence of recurrence and the presence of accelerated bone regeneration. We suggest liquid nitrogen as an adjuvant for the prevention of recurrence and bone regeneration guided with lyophilized bone in conjunction with platelet-rich plasma as a feasible option to accelerate the bone healing process

[Amyand's hernia and complicated appendicitis; case presentation and surgical treatment choice]. / Hernia de Amyand y apendicitis complicada; presentación de un caso y elección de tratamiento quirúrgico.

BACKGROUND: A caecal appendix within an inguinal hernia, with or without appendicitis, is defined as Amyand's hernia. In 1% of inguinal hernias an appendix without inflammation can be found, however, the prevalence of appendicitis in a hernia sac is only 0.08-0.13%. CLINICAL CASE: Male of 43 years old, began two days before admission with pain in the right inguinal region. He was scheduled for surgery due to a complication of a right inguinal hernia. The surgical findings were Amyand's hernia, necrotic spermatic cord, and perforated appendix. Surgical repair was performed with a favourable outcome, and he was discharged on the fourth postoperative day. DISCUSSION: Most of Amyand's hernia exhibit characteristics of incarcerated or strangulated inguinal hernia. Even acute appendicitis or perforated appendix within the hernia sac does not reflect specific symptoms or signs, therefore, a preoperative clinical diagnosis of Amyand's hernia is difficult to achieve. In our case, the patient had perforated appendicitis, developing necrosis of the spermatic cord. Orchiectomy, appendectomy, and inguinal hernia repair was performed without placing mesh. Due to the controversy on the use of mesh in contaminated abdominal wall defects, it was not indicated here, due to the high risk of wound infection and appendicular fistula. CONCLUSION: An extremely rare condition is presented, with a surgical choice that led to a favourable outcome.

[Surgical treatment for liver haematoma following endoscopic retrograde cholangiopancreatography; An unusual case]. / Tratamiento quirúrgico para hematoma subcapsular hepático posterior a colangiografía retrógrada endoscópica; caso inusual.

BACKGROUND: Even in expert hands, there can be serious complications when performing an endoscopic retrograde cholangiopancreatography. The most frequent complications are pancreatitis, cholangitis, bleeding, perforation, and acute cholecystitis. The hepatic subcapsular haematoma is a rare complication, with few cases described worldwide. OBJECTIVE: A case is presented of an extremely rare complication of endoscopic retrograde cholangiopancreatography, which required surgical treatment for its resolution without success. This is second case of mortality reported in the literature. CLINICAL CASE: Female patient of 30 years old, with indication for endoscopic retrograde cholangiopancreatography due to benign strictures. A hydro-pneumatic dilation and stent placement of 2 gauge 10 fr was performed. She presented abdominal pain after the procedure and significant decline in haemoglobin with no evidence of haemodynamic instability so an abdominal tomography scan was performed, showing no evidence of liver injury. The patient was haemodynamic unstable within 72 h. A laparotomy was required for damage control, with fatal outcome in the intensive care unit due to multiple organ failure. CONCLUSION: Subcapsular hepatic haematoma after endoscopic retrograde cholangiopancreatography is a rare complication, with few cases reported in the literature. Treatment described in the literature is conservative, resulting in a satisfactory resolution.
