RESUMO

Background: Outcomes in liver transplantation with organs obtained via donation after cardiocirculatory death (DCD) have been suboptimal compared to donation after brain death, attributed mainly to the high incidence of ischemic cholangiopathy (IC). We evaluated the effect of a 10-year learning curve on IC rates among DCD liver graft recipients at a single centre. Methods: We analyzed all DCD liver transplantation procedures from July 2006 to July 2016. Patients were grouped into early (July 2006 to June 2011) and late (July 2011 to July 2016) eras. Those with less than 6 months of follow-up were excluded. Primary outcomes were IC incidence and IC-free survival rate. Results: Among the 73 DCD liver transplantation procedures performed, 70 recipients fulfilled the selection criteria, 32 in the early era and 38 in the late era. Biliary complications were diagnosed in 19 recipients (27%). Ischemic cholangiopathy was observed in 8 patients (25%) in the early era and 1 patient (3%) in the late era (p = 0.005). The IC-free survival rate was higher in the late era than the early era (98% v. 79%, p = 0.01). The warm ischemia time (27 v. 24 min, p = 0.049) and functional warm ischemia time (21 v. 17 min, p = 0.002) were significantly lower in the late era than the early era. Conclusion: We found a significant reduction in IC rates and improvement in ICfree survival among DCD liver transplantation recipients after a learning curve period that was marked by more judicious donor selection with shorter procurement times.


Contexte: L'issue des greffes de foie suite à un don d'organe après décès cardiocirculatoire (DDC) a été sous-optimale comparativement aux dons suivant la mort cérébrale. Cela serait surtout attribuable à une forte incidence de cholangiopathie ischémique (CI). Nous avons évalué l'effet d'une courbe d'apprentissage échelonnée sur 10 ans sur les taux de CI chez des receveurs de greffe de foie après DDC dans un seul centre. Méthodes: Nous avons analysé toutes les greffes de foie consécutives à des DDC entre juillet 2006 et juillet 2016. Les patients ont été regroupés en 2 époques, la première, de juillet 2006 à juin 2011, et la seconde, de juillet 2011 à juillet 2016. Ceux pour lesquels on disposait de moins de 6 mois de suivi ont été exclus. Les paramètres principaux étaient l'incidence de CI et le taux de survie sans CI. Résultats: Parmi les 73 greffes de foie par suite de DDC, 70 receveurs répondaient aux critères de sélection, 32 pour la première époque et 38 pour la seconde époque. Des complications biliaires ont été diagnostiquées chez 19 receveurs (27 %). La cholangiopathie ischémique a été observée chez 8 patients (25 %) de la première époque et 1 patient (3 %) de la seconde (p = 0,005). Le taux de survie sans CI a été plus élevé pendant la seconde époque que pendant la première (98 % c. 79 %, p = 0,01). Le temps d'ischémie chaude (27 minutes c. 24, p = 0,049) et le temps d'ischémie chaude fonctionnelle (21 minutes c. 17, p = 0,002) ont été significativement plus courts durant la seconde époque que durant la première. Conclusion: Nous avons observé une réduction significative des taux de CI et une amélioration de la survie sans CI chez les receveurs de greffes de foie par DDC après une courbe d'apprentissage qui a été marquée par une sélection plus judicieuse des donneurs et des délais d'obtention plus courts.

RESUMO

BACKGROUND: Early reports of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) outcomes have been suboptimal. The literature has confirmed that learning curves influence surgical outcomes. We have 54 months of continuous experience performing ALPPS with strict selection criteria. This study aimed to evaluate the impact of the learning curve on ALPPS outcomes. METHODS: We retrospectively compared patients who underwent ALPPS between April 2012 and March 2016. Patients were grouped into 2 24-month (early and late) periods. All candidates had a high tumour load requiring staged hepatectomy after chemotherapy response, a predicted future liver remnant (FLR) less than 30% and good performance status. RESULTS: Thirty-three patients underwent ALPPS during the study period: 16 in the early group (median age 65 yr, mean body mass index [BMI] 27) and 17 in the late group (median age 60 yr, mean BMI 25). Bilobar disease was comparable in both groups (94% v. 88%, p > 0.99). Duration of surgery was not statistically different. Intraoperative blood loss and need for transfusion were significantly lower in the late group (200 ± 109 mL v. 100 ± 43 mL, p < 0.05). The late group had a higher proportion of monosegment ALPPS (4:1). There were no deaths within 90 days in either cohort. Rates of postoperative complications were not statistically significant between groups. The R0 resection rate was similar. The entire 1-year disease-free and overall survival were 52% and 84%, respectively. CONCLUSION: Excellent results can be obtained in innovative complex surgery with careful patient selection and good technical skills. Additionally, the learning curve brought confidence to perform more complex procedures while maintaining good outcomes.


CONTEXTE: Les premiers résultats sur l'association de la partition hépatique et de la ligature portale pour l'hépatectomie en 2 temps (ALPPS) sont sous-optimaux. La littérature a confirmé que les courbes d'apprentissage influencent les résultats des interventions chirurgicales. Notre étude reposait sur 54 mois consécutifs d'utilisation de la technique ALPPS selon des critères de sélection rigoureux. Elle visait à évaluer l'effet de la courbe d'apprentissage sur les résultats liés à l'ALPPS. MÉTHODES: Nous avons procédé à une comparaison rétrospective des patients traités par l'ALPPS entre avril 2012 et mars 2016. Nous avons divisé les patients en 2 groupes de 24 mois (précoce et tardif). Tous les candidats avaient une charge tumorale élevée nécessitant une hépatectomie en 2 temps après une réponse à la chimiothérapie, un volume estimé de futur foie résiduel (FFR) inférieur à 30 % et un indice fonctionnel favorable. RÉSULTATS: Trente-trois patients ont été traités par l'ALPPS pendant la période de l'étude : 16 dans le groupe précoce (âge médian 65 ans, indice de masse corporelle [IMC] moyen 27) et 17 dans le groupe tardif (âge médian 60 ans, IMC moyen 25). Le taux de maladie bilobaire était comparable entre les 2 groupes (94 % c. 88 %, p > 0,99). La durée de la chirurgie n'était pas statistiquement différente. Les pertes de sang peropératoires et le besoin de transfusion étaient significativement inférieurs dans le groupe tardif (200 ± 109 mL c. 100 ± 43 mL, p < 0,05). Le groupe tardif avait une proportion plus élevée d'ALPPS mono-segmentaires (4:1). Il n'y a eu aucun décès dans les 90 jours parmi les 2 cohortes. Les taux de complications postopératoires n'étaient pas statistiquement significatifs entre les groupes. Le taux de résection R0 était similaire. Les taux de survie sans récidive après une année complète et de survie globale étaient de 52 % et de 84 %, respectivement. CONCLUSION: L'innovation dans le domaine des chirurgies complexes peut donner d'excellents résultats lorsqu'on sélectionne attentivement les patients et que l'on possède de bonnes habiletés techniques. De plus, la courbe d'apprentissage a eu pour effet d'accroître la confiance dans la capacité de réaliser des interventions complexes tout en produisant de bons résultats.

RESUMO

Retained foreign bodies including gossypiboma could be silent for years. However, in some cases, it can lead to major complications. Gossypiboma is not frequently reported for multiple reasons, including nonspecific presentation clinically and radiologically, and ethical issues. We present a case of a gossypiboma that was retained for more than 20 years causing a severe intestinal obstruction for an elderly female. The intestinal obstruction was initially thought to be adhesive in nature and was managed initially conservatively, but with failure to improve, the patient was taken for exploratory laparotomy, and the foreign body was found attached to the root of the mesentery posterior to the transverse colon. This case sheds light on the fact that although surgical tools are of great utility, they must be managed with utmost care to prevent complications and secure patients' safety.

RESUMO

Intra-peritoneal tuberculosis is a rare disease, accounting for 1-2% of all tuberculosis cases. The absence of characteristic clinical picture of intra-peritoneal tuberculosis makes the diagnosis rarely easy for clinicians as it mimics malignancy. We present a case of a young male patient who presented with peritoneal tuberculosis, aiming to contribute to a better understanding of peritoneal tuberculosis in the literature.

RESUMO

BACKGROUND Re-transplant of a late failing living donor liver graft using another graft from another living donor is a rare occurrence and is associated with high mortality due to the complexity of the procedure. There are only a few such case series reported in the literature, mainly from South Asia and Japan, where living donor liver transplant is commonly performed, and there are no such reports from Western countries. CASE REPORT This is a case of living donor liver re-transplant for a 28-year-old recipient whose graft failed 14 years after his primary living donor transplant for primary sclerosing cholangitis. The second transplant was a right-lobe graft obtained from a living donor. The presence of portal vein thrombosis in the setting of high Model for End-Stage Liver Disease (MELD) score added to the complexity of the case. The procedure was concluded successfully with an uneventful post-operative course. The patient was discharged 3 weeks after the procedure. One-year follow-up showed a normally functioning graft. CONCLUSIONS Successfully re-transplanting a patient with a failing living donor liver graft from a living donor is possible if sufficient surgical expertise is available and the risk and benefit are carefully considered. This is especially important in countries where a cadaveric graft is difficult to obtain due to organ scarcity.
