Surgical Treatment following Chemo-Targeted Therapy with Bevacizumab for Lung Metastasis from Colorectal Carcinoma: Analysis of Safety and Histological Therapeutic Effects in Patients Treated at a Single Institution
Background: Recently, therapeutic strategies for a metastasectomy from colorectal carcinoma after chemo-targeted therapy with bevacizumab have been presented, with which some uncommon but serious adverse events have been reported. However, only few reports have investigated the safety of lung resection after such therapy or the histological effects. We retrospectively analyzed the both of them at our institute. Methods: Of 69 colorectal carcinoma patients who underwent pulmonary metastasectomy procedures from 2009 to 2014, we investigated 11 who also received chemo-targeted therapy prior to surgery. Results: In addition to bevacizumab, 5 fluorouracil (FU)/leucovorin + oxaliplatin or capecitabine was given in 6 cases and 5 FU/leucovorin + irinotecan in 5 cases. The mean period from the end of chemo-targeted therapy to surgery was 2.7 ± 0.9 months. The response to therapy shown in imaging findings was progressive disease in 6, stable disease in 3, and partial response in 2 (response rate, 18.2%). The operation modes were wedge resection (n = 8, 72.3%), segmentectomy (n = 2, 1 in bilateral lobes, 1 in the right lobe, 18.2%), and lobectomy (n = 1, left lower lobectomy, 9.1%). All patients safely underwent a complete resection. As for postsurgical complications, chylothorax occurred in 1 case and prolonged pulmonary air leakage in 1 case. The histological effects of chemo-targeted therapy were slight. There was no relationship between histological findings with imaging findings obtained prior to the operation (p = 0.63). The 5-year disease-free survival rate after metastasectomy was 10.9%. Conclusions: Pulmonary metastasectomy after chemo-targeted therapy for colorectal carcinoma patients obtained acceptable results. In addition, there was no correlation between imaging and histopathologic results following chemo-targeted therapy
Diagnostic effectiveness of preoperative water-soluble contrast enema in colorectal perforation
Summary: Objective: To evaluate the diagnostic usefulness of performing a preoperative water-soluble contrast enema (WSCE) before emergency surgery for colorectal perforation. Methods: We retrospectively reviewed 68 consecutive patients who underwent a preoperative WSCE before emergency surgery for colorectal perforation during the period from January 2011 to December 2017. Clinical characteristics and inflammatory biomarkers were compared between patients with Hinchey I–II versus those with Hinchey III–IV. Results: WSCE leakage occurred in 27 of 68 patients (39.7%). Univariate analysis showed that the two groups (Hinchey I–II and Hinchey III–IV) significantly differed regarding age, perforation site, cause of perforation, American Society of Anesthesiologists grade, presence or absence of WSCE leakage, and white blood cell count. Multivariable analysis revealed that WSCE leakage was a predictor of Hinchey III–IV, with an odds ratio of greater than 24 (P = 0.002). The sensitivity and specificity of WSCE leakage for differentiating those with Hinchey III–IV from those with Hinchey I–II were 76.5% and 97.1%, respectively. Conclusions: This retrospective study indicates that preoperative WSCE before emergency surgery is a useful tool for predicting the presence of Hinchey III–IV in patients with colorectal perforation.
