The caudate lobe of the liver has always been regarded as the deepest segment, with most complicated anatomy. The surgeon’s understanding of the caudate lobe and its subsegments has undergone a complex and tortuous process. In recent years, the special view and fine anatomy of the caudate lobe in laparoscopic resection of caudate lobe of liver have been proved or challenged based on the traditional anatomical knowledge of the liver gross specimen, cast specimen and three-dimensional reconstruction. It is these validations and challenges that keep surgeons revising and restoring the caudate anatomy to its true form. This article will discuss these new ideas and describe the laparoscopic total caudate lobectomy in detail from the point of view of a laparoscopic surgeon.
ObjectiveTo summarize the current comparison of the efficacy of different treatments for recurrent hepatocellular carcinoma.MethodTo search the literatures about the comparative studies on the efficacy of different treatments for recurrent hepatocellular carcinoma in recent years and analyze them.ResultsIn the treatment of recurrent hepatocellular carcinoma, percutaneous arterial chemoembolization combined with radiofrequency ablation could improve the survival rate and tumor-free survival rate to some extent, compared with the single use of percutaneous arterial chemoembolization. In the short term, there was no difference in efficacy between radiofrequency ablation and surgical resection, but the local recurrence rate of radiofrequency ablation was higher than that of surgical resection group. Salvage liver transplantation offered potential opportunity to reduce the risk of recurrence and tended to improve long-term survival outcomes, but liver sources were scarce and costly. ConclusionsAt present, there is no systematic staging scheme and treatment system for recurrent hepatocellular carcinoma. At the same time, most studies are retrospective, and more prospective studies are needed to further explore the treatment of recurrent hepatocellular carcinoma.
Objective To explore the application effect of PDCA cycle management on reducing the unplanned overnight recovery rate in patients undergoing transabdominal preperitoneal inguinal hernia repair (TAPP) under the same-day surgery model. Methods The unplanned overnight recovery rate in patients who underwent TAPP at West China Tianfu Hospital of Sichuan University between January and October 2023 (pre-improvement phase) was analyzed. A quality control group was established, and PDCA cycle management was employed to define control objectives and implement strategies to reduce the unplanned overnight recovery rate. The unplanned overnight recovery rate in patients who underwent TAPP between November 2023 and April 2024 (post-improvement phase) was compared with that in the pre-improvement phase. Results After the implementation of PDCA cycle management, the unplanned overnight recovery rate in patients undergoing TAPP under the same-day surgery reduced from 23.87% (37/155) in the pre-improvement phase to 9.05% (19/210) in the post-improvement phase, with a statistically significant difference (P<0.05). Conclusion The application of PDCA cycle in the process management of TAPP under the same-day surgery model significantly reduces the unplanned overnight recovery rate in patients.
ObjectiveTo evaluate the feasibility and safety of laparoscopic cholecystectomy (LC) in same-day surgery model. MethodsThe patients who underwent LC at West China Tianfu Hospital of Sichuan University from November 1, 2023 to July 31, 2024, were retrospectively reviewed. The enrolled patients were divided into a same-day surgery LC group and a conventional inpatient LC group. In the same-day surgery group, a same-day discharge protocol was implemented, whereby patients were admitted, operated on, and discharged on the same day, with discharge required no later than 21:00 without an overnight stay. The conventional inpatient group was managed according to the conventional model. A comparison was carried out between the two groups concerning baseline characteristics, perioperative outcomes, surgery-related complications, postoperative urinary retention, total length of stay, hospitalization costs, and 30-day follow-up results. ResultsA total of 347 patients were included, comprising 164 in the same-day surgery LC group and 183 in the conventional inpatient LC group. No statistically significant differences (P > 0.05) were found between the two groups in the following terms: total anesthesia time, operative time, intraoperative blood loss, intraoperative fluid infusion, length of stay in the post-anesthesia care unit (PACU), fluid infusion in the PACU, placement of abdominal drains, visual analog scale pain score at discharge, rates of unplanned revisits due to changes in their disease conditionwithin 30 d after discharge, readmission rates, and the incidence of surgery-related complications. All complications in both groups were graded as Clavien-Dindo Ⅰ. The same-day surgery LC group demonstrated significantly lower preoperative fluid infusion, postoperative fluid infusion, total hospitalization costs, and a shorter total length of stay compared to the conventional inpatient LC group (P<0.05). Furthermore, the incidence of postoperative urinary retention was significantly lower in the same-day surgery LC group (P<0.05). ConclusionsThis study demonstrates that same-day surgery LC is a safe and feasible approach for appropriately selected patients. Its outcomes in key perioperative safety metrics are comparable to those of the conventional inpatient LC model, while it offers the significant advantages of effectively reducing the length of hospital stay, lowering medical costs, and decreasing the incidence of certain postoperative complications.
