Abstract

Background

Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS–HIPEC) is an effective but costly procedure for select patients with peritoneal malignancies. The impact of progression along a learning curve on the cost of these procedures is unknown.

Patients and Methods

We performed a retrospective cohort study of patients undergoing CRS–HIPEC from 2016 to 2022 at a single quaternary center. Our study cohort was temporally divided into four equally sized volume quartiles (A, B, C, and D). We utilized cumulative sum plots and split-group analysis to characterize the institutional learning curve based on cost, operative time, length of stay, and morbidity. Multivariable linear regression was performed to estimate costs after adjusting for covariates. Bivariate analysis was performed using a Kruskal–Wallis test to compare continuous variables and a χ2 test to compare categorical variables.

Results

Of 201 patients, the median age [interquartile range (IQR)] was 57 (47–65) years, 113 (56%) patients were female, 143 (71%) were white, and 107 (53%) had private insurance. Median operating room charge [US$42,639 (US$32,477–54,872), p < 0.001] varied between volume quartiles, peaking in quartile C. Stabilization was achieved for 86 cases for operating room cost, 88 cases for routine cost, 96 cases for length of stay, 103 cases for operative time, 120 cases for intensive care unit length of stay, and 150 cases for overall and serious morbidity. The actual operating room and routine costs were similar to predicted costs at the end of the study period.

Conclusions

The CRS–HIPEC learning curve is triphasic, with cost stability achieved relatively early compared with other markers of surgical proficiency.

Neu im Fachgebiet Chirurgie

Welcher Zugangsweg ist besser für den interventionellen Mitralklappenersatz?

Bisher wird für den interventionellen Mitralklappenersatz standardmäßig der transapikale Zugangsweg gewählt. In einer Registeranalyse hat dieser in puncto Sicherheit allerdings den Kürzeren gezogen.

Lohnt sich die Karotis-Revaskularisation?

Die medikamentöse Therapie für Menschen mit Karotisstenosen hat sich in den vergangenen Dekaden verbessert. Braucht es also noch einen invasiven Eingriff zur Revaskularisation der Halsschlagader bei geringem bis moderatem Risiko für einen ipsilateralen Schlaganfall?

Höhere Dosis von Dexamethason senkt Überlebenschancen

Personen mit Hirnmetastasen, die perioperativ höhere kumulative Dosen von Dexamethason erhalten, haben eine schlechtere Prognose. Um die Ergebnisse zu verbessern, bedarf es strengerer Dosierungsschemata.

Appendektomie erhält Remission bei Colitis ulcerosa

Wird der Wurmfortsatz bei Personen mit Colitis ulcerosa entfernt, ist die Rückfallrate um ein Drittel geringer als unter konservativer Behandlung. Auch die Lebensqualität verbessert sich und der Bedarf an Medikamenten nimmt ab.
