Laparoscopic-Assisted Longitudinal Incision and Transverse Anastomosis: A Novel Surgical Approach for Treatment of Esophageal Stenosis Caused by Tracheobronchial Remnants.

Purpose: To review the treatment of lower congenital esophageal stenosis caused by tracheobronchial remnants (TBR) and to introduce a novel technical approach through laparoscopic surgery. Methods: Patients with TBR who underwent surgery in our single-center from January 2016 to December 2019 were enrolled. Resection of cartilage with stenotic esophageal segment and end-to-end anastomosis was the traditional surgery. Since 2018, longitudinal incision with partial resection of cartilage loop in the anterior esophageal wall and the transverse suture was conducted endoscopically. We reviewed the treatment, followed-up with these patients, and discussed the new procedure's preponderance. Main Results: Thirteen patients underwent surgery and were followed-up for 0.5-45 months (M = 13) after surgery. Twelve patients showed good physical development with a regular diet. One patient, who was 2 weeks after the surgery, was fed by a soft diet and regularly followed-up at our clinic. In 13 cases, five patients underwent traditional laparotomy with pyloroplasty. Two patients who went through anastomotic leakage were cured by drainage and conservative treatments. Anastomotic stricture that occurred in two cases was improved by one-time of dilation. The administration time of parenteral nutrition (PN) was 9.0 ± 1.4 days. The length of hospitalization was 36.6 ± 5.2 days. Eight cases underwent the new surgical approach through laparoscopy or thoracoscopy. Pyloroplasty was avoided since the vagal close to the posterior wall of the esophagus was protected. Gastric motility disorder did not occur as expected. No leakage occurred postoperatively. The anastomotic stricture was found in six cases and improved after one to five times of dilations. The length of hospitalization dropped to 18.6 ± 6.9 days significantly (P < .001). Conclusions: Longitudinal incision and transverse anastomosis of the anterior wall of the esophagus with partial resection of cartilage without pyloroplasty through endoscopy is a novel practical surgical approach to treat patients with TBR.

Peripherally inserted central venous catheter-associated complications exert negative effects on body weight gain in neonatal intensive care units.

BACKGROUND AND OBJECTIVES: The placement of a peripherally inserted central venous catheter (PICC) is an essential procedure in neonatal intensive care units (NICU). The aim of this study was to determine the risk of PICC complications in NICU, and further identify the effects of PICC complications on body weight gain in premature infants. METHODS AND STUDY DESIGN: A total of 304 premature infants who had a PICC inserted in NICU were enrolled in this study. The weight-for-age z-score (WAZ) at the time of PICC insertion and removal were calculated, and changes of WAZ in different groups were compared using a t-test. Risk factors for PICC complications were assessed using the chi-squared test and multiple logistic regression analysis. RESULTS: Thirty (9.97%) PICCs were removed due to complications. Of them, 14 PICCs were removed because of non-infectious complications and 16 PICCs were removed for central-line-associated bloodstream infections (CLABSIs). Multiple logistic regression analysis showed that premature infants with birth weight >1,500 g were less likely to have PICC complications than infants with birth weight <=1,500 g (OR, 0.29; 95% CI: 0.10-0.82; p=0.020). In addition, the changes in WAZ between PICC insertion and removal were significantly different in both infectious (-0.144±0.122, p<0.005) and non-infectious (-0.65±0.528, p<0.001) complications groups, compared with the no complications group (0.291±0.552). CONCLUSIONS: Findings from this study suggest that birth weight is a risk factor for PICC-associated complications in the NICU, and both infectious and non-infectious PICC complications are associated with poor body weight gain in premature infants.
