ABSTRACT

Objective:To evaluate the feasibility of abandoning prophylactic abdominal drainage in patients undergoing minimally invasive minor hepatectomy based on a propensity score matching (PSM) study.Methods:Retrospective review of a prospectively collected database of patients undergoing minimally invasive minor hepatectomy from July 2022 to May 2023 at the Department of Hepatopancreatobiliary Surgery and Minimally Invasive Surgery, Zhejiang Provincial People's Hospital. A total of 108 patients were enrolled, including 48 males and 60 females, aged (60.8±13.7) years old. According to whether the abdominal drainage tube was prophylactically placed intraoperatively, patients were divided into two groups: the drainage group (with prophylactic placement of abdominal drainage tubes, n=76); the no-drainage group (without prophylactic placement of abdominal drainage tubes, n=32). PSM was used to compare the perioperative data between the groups, including extent of liver resection, intraoperative blood loss, operative time, and postoperative complications. Postoperative survival status within 90 days was followed up through telephone review. Results:Before PSM, the two groups differed significantly on age and the history of hypertension (both P<0.05). After PSM, there were 23 patients in each group. Patients in the two groups showed comparable results regarding the intraoperative parameters including the surgical method, pathological types, the number and maxium diameter of hepatic lesions, the extent and complexity of liver resection, and the duration of hepatic inflow occlusion (all P>0.05). No postoperative intra-abdominal bleeding occurred in either group. The incidences of postoperative complications were comparable between the groups, including fever, bile leakage, incision infection, and abdominal acupuncture for drainage (all P>0.05). After PSM, compared to patients wothout prophylactic abdominal drainage, prophylactic abdominal drainage group showed a decreased white blood cell counts on postoperative day 1 [9.39(6.30, 10.58)×10 12/L vs. 13.19(10.15, 14.90)×10 12 /L, P=0.006] and a shorter length of postoperative hospital stay [4(3, 5) d vs. 5(4, 5) d, P=0.033]. No postoperative death within 90 days occurred in either group. Conclusion:In minimally invasive minor hepatectomy, abandoning prophylactic abdominal drainage could be feasible, which facilitates fast recovery without increasing the incidence of postoperative fever, perihepatic fluid accumulation and postoperative abdominal acupuncture for drainage.

ABSTRACT

Objective:To study the safety and feasibility of en-bloc lymph node dissection in laparoscopic radical resection for gallbladder cancer(GBC).Methods:The clinical data of 87 patients who underwent laparoscopic radical resection for GBC at Zhejiang Provincial People's Hospital from January 2014 to February 2022 were retrospectively analyzed. There were 26 males and 61 females, aged 67.0 (59.0, 72.0) years old. The patients were divided into the en-bloc dissection group ( n=29) and the non-en-bloc dissection group ( n=58) based on whether en-bloc lymph node dissection was carried out. Differences in general data, tumor characteristics, operation, recurrence and survival were compared between the two groups. Postoperative survival status of these patients was followed-up by telephone. Results:The number of lymph nodes dissected in the en-bloc dissection group was 9.0(8.0, 12.0), which was significantly higher than the 8.0(4.8, 11.0) in the non-en-bloc dissection group ( Z=-2.39, P=0.017). There were no significant differences in age, gender, preoperative blood biochemical indexes, tumor carbohydrate antigen 19-9, tumor stage, nerve and vascular invasion, operation time, intraoperative blood loss, postoperative drainage tube retention time, postoperative hospital stay, and incidences of postoperative complications (biliary fistula, abdominal hemorrhage and abdominal infection) between the two groups (all P>0.05). The median survival was longer in the en-bloc group than in the non-en-bloc group (21 vs. 15 months), and the median relapse-free survival time was 18 months in the en-bloc group compared with 10 months in the non-en-bloc group. However, there were no significant differences in postoperative cumulative survival and recurrence-free survival between the two groups (all P>0.05). Conclusion:En-bloc lymphadenectomy was safe and feasible in laparoscopic radical GBC surgery, with more lymph nodes being removed than the non-en-bloc lymphadenectomy group.

ABSTRACT

Objective:To compare the treatment outcomes between laparoscopic versus open radical resection for hilar cholangiocarcinoma (HCCA).Methods:From January 2017 to January 2020, the clinical data of 34 patients who underwent radical resection for HCCA were retrospectively collected and analyzed. These patients were divided into the laparotomy group ( n=17) and the laparoscopic group ( n=17) based on the operation they received. Clinical data including perioperative outcomes, oral re-intake time, first out-of-bed activity time, drainage tube removal time, postoperative hospital stay, 30-day and 90-day mortality rates were compared between groups. Results:Of 34 patients who underwent radical for HCCA in the study, there were 16 males and 18 females, aged (64.3±1.7) years. The mean operation time of the laparotomy group was significantly less than those in the laparoscopic group [(436.2±33.4) vs (522.1±24.0) min, P<0.05]. The 2 groups showed comparable results in extent of operation, intraoperative bleeding, incidences of portal vein reconstruction, yields of lymph nodes, and tumor diameter. The laparoscopic group showed advantage trends over the laparotomy group in incidences oral re-intake time [(4.7±0.3) vs (4.6±0.3) days], first out-of-bed activity time [(2.9±0.4) vs (2.2±0.3) days], drainage tube removal time [(12.7±1.3) vs (11.1±1.0) days] and postoperative hospital stay [(18.3±1.7) vs (15.8±1.3) days], but the differences failed to reach statistical significance ( P>0.05). Conclusion:Compared with open surgery, laparoscopic radical resection of HCCA in properly selected patients, was safe and feasible. There were comparable clinical outcomes.

ABSTRACT

Objective To investigate the clinical roles of lysine methyltransferase 5A(KMT5A)in human hepatocellular carcinoma(HCC)and its functions in cell migration and invasion. Methods The expression levels of KMT5A of 60 cases were detected by immunohistochemistry(IHC). KMT5A siRNA was used to down-regulate the expression of KMT5A in SMMC-7721 cells. Cell migration and invasion were measured by wound healing assays and transwell assays,respectively. Immunoblotting was used to detect the expression of MMP-2 after siRNA trans-fection. miR-186 mimics were transfected into SMMC-7721 cells and the mRNA levels of KMT5A was detected by qRT-PCR after transfection. Results High expression of KMT5A was associated with large tumor diameter (>5 cm,P=0.047)and advanced TNM stage(Ⅲ+Ⅳ,P=0.035). The expression of KMT5A was knocked down by siRNA in SMMC-7721 cells. Down-regulation of KMT5A suppressed cell migration(P=0.031,P=0.006)and invasion(P=0.010),and impaired MMP-2 expression(P=0.040). Overexpression of miR-186 could significantly inhibit the expression of KMT5A(P = 0.007). Conclusions Over-expression of KMT5A in HCC tissues associ-ates with poor clinical features. KMT5A knockdown inhibits the migration and invasion on HCC cells.
