The angle of the median line of the vas deferens and spermatic vessels (MVS) was also calculated.Results: Between 2018 and 2022, 70 inguinal hernia lesions underwent robot-assisted inguinal hernia repair. Under adjustment according to lateral tilt of the scope, the mean angles of the IEVs and MVS were 14.1° laterally (SD = 15.9°) and -1.5° medially (SD = 15.8°), respectively.Conclusion: The IEVs and MVS do not always adopt an absolutely vertical course, and some structures run obliquely.

As the EGJ is located at the boundary between the thoracic and abdominal cavities, the optimal surgical approach is a subject of debate and estimation of the esophageal invasion length (EIL) is an important factor in its selection.Methods: Data from our in-house database were extracted for consecutive patients with Siewert type I, II and III EGJ adenocarcinoma (EIL ≤ 4 cm), who underwent transhiatal or transthoracic surgical resection between 2010 and 2016. The clinical records of these patients were reviewed and the accuracy of EIL estimation and its discrepancy with the pathological measurement were analyzed.Results: A total of 82 patients were included in the final analysis. We established that EIL was underestimated in 49 of these patients (59.8%). The mean-distance discrepancy between the preoperative and pathological diagnosis of EIL in the underestimation group was 7.0 mm. Multivariate analysis revealed that submucosal cancer spread was an independent risk factor for underestimation (P < 0.01). The mean length of submucosal cancer spread was longer for undifferentiated histologic type EGJ adenocarcinomas. (P < 0.01).Conclusions: The EIL was underestimated in approximately 60% of EGJ adenocarcinomas requiring surgical treatment. Thus, careful management is necessary, especially for EGJ adenocarcinoma of the undifferentiated histologic type.","PeriodicalId":22163,"journal":{"name":"Surgery Today","volume":" ","pages":"768-777"},"PeriodicalIF":1.7,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142584385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Histopathological examination of the aneurysm wall specimens was performed and the relationship of the histopathological findings with IgG4-VD was investigated.Results: The median aneurysm diameter at EVAR was 53 mm (interquartile range [IQR] 50-55), and the aneurysm diameter at open surgery was 79 mm (IQR 75-88).

We analyzed both handgrip force and skeletal muscle area and classified patients as having GLIM malnutrition or modified GLIM malcondition. We also evaluated clinicopathological factors, short-term outcomes, and prognoses.Results: The GLIM criteria identified 47 patients (41.2%) with malnutrition and 13 patients (11.4%) with modified GLIM malcondition. Overall survival (P = 0.009) and recurrence-free survival (P = 0.016) were significantly different between the well-nourished and malnourished patients according to the GLIM criteria. Furthermore, modified GLIM criteria malcondition was a significant prognostic factor for both recurrence-free and overall survival (P = 0.002 and P < 0.001, respectively). Multivariate analysis identified a higher carcinoembryonic antigen level and modified GLIM malcondition as predictors of overall and recurrence-free survival.

High-dose oral acetaminophen is effective; however, the safety of its long-term use has not been established in gastrointestinal surgeries. This study aimed to investigate drug-induced liver injury (DILI) in patients with colorectal cancer using high-dose acetaminophen.Methods: One hundred sixty-eight consecutive colorectal cancer using high-dose oral acetaminophen (3600 mg/day between postoperative day 1 and 7) were enrolled.Results: One hundred forty-nine patients (88.7%) completed the administration of high-dose oral acetaminophen. DILI occurred in 58 patients (34.5%), and the cumulative incidence rates were 20.4% and 37.9% on postoperative 6 and 7, respectively. The severity of liver injury was grade 1 in all cases and returned to normal without treatment. Patients with DILI had a higher frequency of dyslipidemia (44.8% vs. 23.6%, P = 0.0047) and M1 staging (10.3% vs. 1.0%, P = 0.0036).

Pharmacological prophylaxis was associated with a higher incidence of VTE than mechanical or no prophylaxis for all procedures. Combined prophylaxis resulted in a lower incidence of VTE than pharmacological prophylaxis alone. Pharmacological prophylaxis was also associated with an increased incidence of bleeding events. The risk of cardiac arrest and death was higher in patients with pulmonary embolism (PE), but there was a trend toward lower mortality in the group that received pharmacological prophylaxis.Conclusion: Pharmacological prophylaxis for VTE was limited in reducing the incidence of VTE, but it may reduce the risk of death.

The learning curve was evaluated using the cumulative sum of the operative times in all cases and was analyzed separately for simple and complex segmentectomies.Results: After applying the cumulative sum method to all cases, we obtained a graph of the operative time that showed three well-differentiated phases: phase 1 (n = 23), the initial learning phase; phase 2 (n = 28), the increased competence phase; and phase 3 (n = 49), the highest skill phase. Comparing phases 1 and 2 with phase 3, we found significant differences in operative time (P < 0.001); however, no significant differences were observed in bleeding or rate of postoperative complications. We observed a significant reduction in operative time after 25 simple segmentectomies and 22 complex segmentectomies.Conclusions: The data suggested that the inflection point of the learning curve was achieved in 51 cases.
