Background: Acute volvulus of the gastric conduit is a rare complication after esophagectomy that warrants surgical intervention and is associated with increased morbidity and mortality. The aim of the study is to evaluate whether fixation of the gastric conduit would reduce the incidence of postoperative volvulus following esophagectomy. Methods: This single-center retrospective analysis of patients who underwent esophagectomy was conducted to determine the incidence of acute postoperative volvulus following a change in practice. All patients who underwent an esophagectomy from September 2013 to November 2022 were included. We compared postoperative outcomes of gastric conduit volvulus, reoperations, morbidity, and mortality among those who had fixation versus non-fixation of the conduit to the right pleural edge. Results: Two hundred and forty-two consecutive patients underwent minimally invasive esophagectomy (81% male, 41% were < 67 years old). The first 121 (50%) patients did not undergo fixation of the gastric conduit, while the subsequent 121 (50%) patients did undergo fixation. Comparing both groups, there were no significant differences in major complications, anastomotic leak, and 30-day and 90-day all-cause mortality. Four (2%) patients developed gastric conduit volvulus in the non-fixation group, requiring reoperative intervention. Following implementation of fixation, no patient experienced gastric volvulus. Conclusion: Acute volvulus of the gastric conduit is a rare complication after esophagectomy. Early diagnosis and surgical intervention are critical. In this study, although not statistically significant, fixation of the gastric conduit did reduce the number of patients who experienced postoperative volvulus. Additional future studies are needed to validate this technique and the prevention of postoperative acute gastric conduit volvulus among a diverse patient population. [ABSTRACT FROM AUTHOR]

Purpose: The objective of this study was to review the collective experience and utility of FDG-PET scans (FDG-PET) in the detection of systemic metastases in patients with stage III melanoma. Methods: A systematic search for relevant studies published between 1990 and 2012 was performed. We included English language studies that evaluated melanoma patients with stage III disease, with at least 10 patients per study, and collected statistical data to assess FDG-PET utility in the detection of distant metastases. The SIGN tool was used to evaluate methodological quality and a meta-analysis was performed using Stata statistical software to quantify the clinical utility of FDG-PET. Results: The systematic search yielded 9 studies eligible for inclusion in quantitative analyses with a total of 623 patients. The overall sensitivity of FDG-PET in detecting systemic metastases was 89.42% (95% CI: 65.07-97.46), and specificity was 88.78% (95% CI: 77.04-94.91). The pooled positive likelihood ratio was 7.97 (95% CI: 3.58-17.71) and the negative likelihood ratio was 0.12 (95% CI: 0.03e0.47). The area under the summary receiver operating curve (SROC) was 0.94 (95% CI: 0.92-0.96) and the diagnostic odds ratio (DOR) was 66.84 (95% CI: 10.66-418.89). A change in stage and/or management was noted in 22% (126/ 573) of patients when FDG-PET was utilized. Conclusions: Our findings indicate that FDG-PET may be useful in detecting distant metastases in patients with stage III melanoma. For this highly selected group of patients, FDG-PET has a high sensitivity, specificity and performance, frequently leading to a change in treatment plan. [ABSTRACT FROM AUTHOR]
