Purpose: Limited data exist on the use of low midline and transverse incisions for specimen extraction or stoma sites in laparoscopic rectal cancer surgery (LRCS). We compared the short-term and medium-term outcomes of these incisions and assessed whether wound complications in specimen extraction sites (SES) are increased by specimen extraction through the stoma site (SESS) in LRCS. Methods: From March 2010 to December 2017, 189 patients who underwent LRCS and specimen extraction through low abdominal incisions were divided into 2 groups: midline (n = 102) and transverse (n = 87), and perioperative outcomes were compared. Results: The midline group showed a higher frequency of temporary stoma formation (P = 0.001) and splenic flexure mobilization (P < 0.001) than the transverse group. The overall incisional hernia and wound infection rates in the SES were 21.6% and 25.5%, respectively, in the midline group and 26.4% and 17.2%, respectively, in the transverse group (P = 0.494 and P = 0.232, respectively). In patients who underwent SESS, the incisional hernia and wound infection rates of SES after stoma closure were 39.1% and 43.5%, respectively, in the midline group, and 35.5% and 22.6%, respectively, in the transverse group (P = 0.840 and P = 0.035, respectively). Conclusion In terms of incisional hernia and wound infection at the SES, a low midline incision may be used as a low transverse incision in patients without temporary stoma in LRCS. However, considering the high wound complication rates after stoma closure in patients with SESS in this study, SESS should be performed with caution in LRCS.

Purpose: The use of gallium-68 prostate-specific membrane antigen-11 positron emission tomography/computed tomography (Ga-68 PSMA-11 PET/CT) is becoming increasingly common among men with prostate cancer (PCa). However, it remains uncertain which patients will derive the most benefit, and there is a scarcity of real-world data regarding its impact on altering treatment plans. This study investigated which patients would most benefit from Ga-68 PSMA-11 PET/CT, focusing on detection rates and changes in treatment strategies, drawing from a single-center experience. Materials and Methods: In total, 230 men with PCa who underwent Ga-68 PSMA-11 PET/CT between November 2021 and August 2022 were included in this retrospective study. The patients were classified into 5 groups based on their disease status: group 1, further work-up for high-risk localized PCa; group 2, de novo metastatic PCa; group 3, biochemical recurrence after definitive treatment; group 4, castration-resistant PCa; group 5, others. The positivity rate, positive lesions, predictive value of lymph node metastases, comparison with conventional images, and treatment changes after Ga-68 PSMA-11 PET/CT were analyzed in each group. Results: Of the 230 patients, 40 (17.4%), 20 (8.7%), 77 (33.5%), 76 (33.0%), and 17 (7.4%) were classified into groups 1–5, respectively. Ga-68 PSMA-11 PET/CT showed lesions in 74.8% of patients, and the optimal cutoff value for PSA was 1.99 ng/mL. Lesions not observed on conventional imaging were found in 62 patients (33.2%). In 38 patients (13.5%), treatment was changed due to Ga-68 PSMA-11 PET/CT. Conclusions These real-world data suggest that Ga-68 PSMA-11 PET/CT may be clinically useful for various disease conditions, as substantial stage migration and subsequent treatment changes occur in men with PCa. However, the prognostic impact of this modality remains unclear; thus, a well-designed prospective study is needed to address this issue.
