Optimal cytoreduction: is a CT's picture worth a surgeon's word?

INTRODUCTION: The presence of residual disease after cytoreductive surgery is subjectively determined by the surgeon at the end of the operation. Nevertheless, in up to 21-49% of CT scans, residual disease can be found. The aim of this study was to establish the relationship between post-surgical CT findings after optimal cytoreduction in patients with advanced ovarian cancer and oncological outcome. MATERIAL AND METHODS: Patients with advanced ovarian cancer (FIGO II and IV), diagnosed between 2007 and 2019 in Hospital La Fe Valencia, in whom cytoreductive surgery was performed, achieving R0 or R1, were assessed for eligibility (n = 440). A total of 323 patients were excluded because a post-operative CT scan was not performed between the third and eighth post-surgery week and prior to the start of chemotherapy. RESULTS: 117 patients were finally included. The CT findings were classified into three categories: no evidence, suspicious or conclusive of residual tumour/progressive disease. 29.9% of CT scans were "conclusive of residual tumour/progressive disease". No differences were found when the DFS (p = 0.158) and OS (p = 0.215) of the three groups were compared (p = 0.158). CONCLUSION: After cytoreduction in ovarian cancer with no macroscopic disease or residual tumour < 1 cm result, up to 29.9% of post-operative CT scans before chemotherapy found measurable residual or progressive disease. Notwithstanding, a worse DFS or OS was not associated with this group of patients.

Uso de vasopresina y suturas transfixivas para el tratamiento quirúrgico de la gestación ectópica intersticial / Use of vasopressin and transfixive sutures for the surgical treatment of interstitial ectopic gestation

Resumen La gestación cornual, también conocida como intersticial, es una gestación ectópica infrecuente que ocurre en 1/2500 a 1/5000 de los embarazos cuando el embrión implanta en el trayecto intramiometrial de la porción proximal de la trompa. Puede debutar como shock hipovolémico en un 25% de los casos, conllevando una mortalidad de hasta un 2,5%. Mediante ecografía se encuentra un saco gestacional excéntrico y rodeado por una fina capa de miometrio. El tratamiento, en la mayoría de los casos, es quirúrgico, y el control de la hemostasia supone todo un reto. Se presentan dos casos clínicos de mujeres con diagnóstico de gestación intersticial en quienes se realizó exéresis por laparoscopia tras inyección de vasopresina, permitiendo así controlar el sangrado. En una de las pacientes se practicaron también puntos transfixivos transitorios en la arteria uterina y el ligamento útero-ovárico.

Abstract Cornual gestation, also known as interstitial, is a rare ectopic gestation that occurs in 1/2500 to 1/5000 of pregnancies when the embryo implants in the intramyometrial tract of the proximal tube. It can debut as hypovolemic shock in 25% of cases, leading to a mortality rate of up to 2.5%. Using ultrasound, we will find an eccentric gestational sac surrounded by a thin layer of myometrium. Treatment, in most cases, is surgical and control of hemostasis is a challenge. Two clinical cases are presented of women with a diagnosis of interstitial pregnancy in whom transient transfixive sutures were performed at the level of the uterine artery and uterine-ovarian ligament and injection of vasopressin prior to laparoscopic exeresis, thus allowing the bleeding to be controlled.
