Intermittent pneumatic compression in combination with low-molecular weight heparin in the prevention of venous thromboembolic events in esophageal cancer surgery.

INTRODUCTION: Aim of this study was to evaluate the use of Intermittent Pneumatic Compression (IPC) in the prevention of symptomatic venous thromboembolic events (VTE) in patients undergoing esophagectomy for cancer. METHODS: From a prospective database, all patients operated between 2010 and 2014 received IPC in addition to LMWH and were compared to a historical cohort of patients treated LMWH only (2004-2009). RESULTS: Of the 313 included patients, 195 (62%) received IPC. Patients with IPC received neoadjuvant chemoradiation more often (45% vs. 3%, P < 0.001), whereas, neoadjuvant chemotherapy was equally distributed (31% vs. 34%, P = 0.631). There were no differences with regard to surgical approach, operative time, blood loss, and ICU stay. Patients treated without IPC had a longer hospital stay (18 vs. 15 days, P = 0.014). Overall, 12 clinical VTE's occurred in 11 patients, which consisted of two deep venous thromboses and 10 pulmonary embolisms. In the group of patients, who received IPC 1.5% developed a symptomatic VTE compared to 6.8% in patients without IPC (OR = 0.215; 95% CI = 0.06-0.83). Multivariate analysis identified IPC as the only independent prognostic factor correlated with a reduction in postoperative VTE's (OR = 0.225; 95% CI = 0.06-0.88). CONCLUSION: The addition of IPC in patients undergoing esophagectomy for cancer was associated with a reduction in symptomatic VTE's. J. Surg. Oncol. 2017;115:181-185. © 2017 Wiley Periodicals, Inc.

Perioperative Treatment, Not Surgical Approach, Influences Overall Survival in Patients with Gastroesophageal Junction Tumors: A Nationwide, Population-Based Study in The Netherlands.

BACKGROUND: Resectable gastroesophageal junction (GEJ) tumors are treated either with an esophageal-cardia resection or with gastrectomy. The difference in outcome between these two treatment modalities is unknown; Therefore, the aim of this study was to evaluate population-based treatment strategies for patients with resectable adenocarcinomas of the GEJ and to compare the oncological outcomes. METHODS: Patients with potentially resectable GEJ tumors diagnosed between 2005 and 2012 were selected from the nationwide, population-based Netherlands Cancer Registry. Differences between patients were compared using the χ (2) test, and survival curves were generated using the Kaplan-Meier method. Overall multivariate survival was assessed using Cox regression analyses. RESULTS: Patients treated with esophagectomy (n = 939) were significantly younger than patients treated with gastrectomy (n = 257; 64 vs. 66 years; p < 0.001), and no differences were noted regarding lymph node yield, lymph node ratio, and radicality. Patients treated with an esophagectomy or gastrectomy exhibited comparable overall 5-year survival rates (36 vs. 33 %, respectively; p = 0.250). Multivariate analysis showed that patients receiving perioperative treatment and gastrectomy exhibited similar overall survival rates compared with patients receiving perioperative treatment and esophagectomy [hazard ratio (HR) 1.9, 95 % confidence interval (CI) 0.7-1.3; p = 0.908]; however, patients receiving esophagectomy alone (HR 1.3, 95 % CI 1.3-1.8; p = 0.002) or gastrectomy alone (HR 1.8, 95 % CI 1.4-2.4; p < 0.001) exhibited a significantly worse overall survival. CONCLUSIONS: The chosen type of surgery (esophagectomy or gastrectomy) did not influence the overall survival in our cohort of patients with GEJ tumors. The administration of perioperative chemo(radio)therapy improved survival regardless of the surgical approach.

Infant's Age Influences the Accuracy of Rectal Suction Biopsies for Diagnosing of Hirschsprung's Disease.

BACKGROUND & AIMS: Hirschsprung's disease (HD) is a rare birth defect of the distal colon. Analysis of rectal suction biopsy (RSB) is considered to be the most reliable method for its diagnosis in infants. However, the diagnostic accuracy of RSB analysis could be affected by the patient's age, possibly because of rapid development of the enteric nervous system in the first weeks after birth. Because there is a trend toward testing for HD at early ages, we aimed to determine whether the diagnostic accuracy of RSB analysis is associated with the patient's age. METHODS: We performed a retrospective analysis of all patients from whom 1 or more RSBs were analyzed from 1975 through 2011 (529 RSBs from 441 patients). Outcomes of RSB analyses were categorized as positive, inconclusive, or negative for HD. Primary diagnoses, based only on RSB, were compared with final diagnoses made after at least 1 year of clinical follow-up. Age at time of RSB analysis was corrected for the gestational age. By using these criteria, we determined the diagnostic accuracy of RSB analysis for different age groups. RESULTS: RSB analysis identified HD in patients with sensitivity values of 46% (patients -45 to 7 days old), 47% (8-22 days old), and 62% (23-39 days old) (corrected for gestational age). The average sensitivity with which RSB analysis identified HD in patients older than 39 days was 88%. RSB identified HD in patients younger than 39 days old with significantly lower sensitivity than in older patients (50% vs 88%, P < .001). The specificity with which RSB identified infants without HD was not affected by age (average 95%). Of all RSBs, 11% were inconclusive for the diagnosis of HD. CONCLUSIONS: RSB analysis identifies HD in patients younger than 39 days old with only 50% sensitivity. Moreover, RSBs obtained from younger patients often lead to inconclusive outcomes and require additional biopsies. We propose that for infants suspected of HD at these ages, a noninvasive technique, such as anorectal manometry, should be used for a primary diagnosis. RSB should thereafter be used to confirm the diagnosis when the infant is older than 39 days.

Hiatal Hernia After Esophagectomy for Cancer.

BACKGROUND: Hiatal hernia (HH) after esophagectomy is becoming more relevant due to improvements in survival. This study evaluated and compared the occurrence and clinical course of HH after open and minimally invasive esophagectomy (MIE). METHODS: The prospectively recorded characteristics of patients treated with esophagectomy for cancer at 2 tertiary referral centers in the United Kingdom and the Netherlands between 2000 and 2014 were reviewed. Computed tomography reports were reviewed to identify HH. RESULTS: Of 657 patients, MIE was performed in 432 patients (66%) and open esophagectomy in 225 (34%). A computed tomography scan was performed in 488 patients (74%). HH was diagnosed in 45 patients after a median of 20 months (range, 0 to 101 months). The development of HH after MIE was comparable to the open approach (8% vs 5%, p = 0.267). At the time of diagnosis, 14 patients presented as a surgical emergency. Of the remaining 31 patients, 17 were symptomatic and 14 were asymptomatic. An elective operation was performed in 10 symptomatic patients, and all others were treated conservatively. During conservative treatment, 2 patients presented as a surgical emergency. An emergency operation resulted in a prolonged intensive care unit stay compared with an elective procedure (3 vs 0 days, p < 0.001). In-hospital deaths were solely seen after emergency operations (19%). CONCLUSIONS: HH is a significant long-term complication after esophagectomy, occurring in a substantial proportion of the patients. The occurrence of HH after MIE and open esophagectomy is comparable. Emergency operation is associated with dismal outcomes and should be avoided.

Robot-Assisted Laparoscopic Hiatal Hernia Repair: Promising Anatomical and Functional Results.

BACKGROUND: There is no consensus on the optimal technique for hiatal hernia (HH) repair, and considerable recurrence rates are reported. The aim of this study was to evaluate the perioperative outcomes, quality of life (QoL), and recurrence rate in patients undergoing robot-assisted laparoscopic HH repair. MATERIALS AND METHODS: All patients who underwent robot-assisted laparoscopic HH repair between July 2011 and March 2015 were evaluated. The procedure consisted of hernia sac reduction, crural repair without mesh, and Toupet fundoplication. Postoperative radiological imaging or endoscopy was performed in all symptomatic patients to exclude recurrence. Perioperative results were collected retrospectively from the patient records. QoL was evaluated with Short Form-36 (SF-36), Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQOL), and Gastrointestinal Quality of Life Index (GIQLI) questionnaires. RESULTS: A total of 40 patients were identified. The majority (75%) had a type III HH. Median operation time was 118 (62-173) minutes; median blood loss was 20 (10-934) mL, and one procedure was converted to an open procedure. In 6 (15%) patients, postoperative complications occurred, including 2 grade II and 1 grades I, III, IV, and V, according to the Clavien-Dindo classification. Median hospital stay was 3 (1-15) days. At a median follow-up of 11 months, radiological imaging was performed on indication in 12 (30%) patients, and 1 recurrence was found. Overall QoL scores were satisfactory, and there was no difference related to the time elapsed since surgery. CONCLUSION: Robot-assisted laparoscopic HH repair followed by Toupet fundoplication demonstrated a very low short-term recurrence rate. Postoperative morbidity was minimal, and a satisfactory QoL was achieved.
