Background: Patients with tracheobronchial stenosis due to tuberculosis (TSTB) have a variable clinical course and response to treatment including airway intervention. There are no clear guidelines on the best approach to manage such patients. This study examines long-term outcomes of patients with TSTB and factors associated with recurrent symptoms or need for repeat airway intervention following initial bronchoscopic intervention. Methods: This is a retrospective analysis of patients with TSTB over an 18-year period. Symptoms, radiological, bronchoscopic findings, airway interventions and complications were obtained. Multivariate logistic regression analysis was performed to identify factors predictive of recurrence of symptoms or need for repeat airway intervention. Results: A total of 131 patients with mean age 50±18 years and median follow-up 5 (interquartile range, 2-10) years were included. Nineteen (29.7%) patients underwent balloon dilatation alone, 22 (34.4%) had additional resection or stenting, and 19 (29.7%) underwent all 3 procedures. Among patients conservatively managed, a larger proportion (55.6%) of patients with no recurrence of symptoms had active TB. Patients who developed recurrent symptoms had longer symptom duration (12 vs. 3 months, P=0.025), and more had recurrent lower respiratory tract infections (50% vs. 5.6%, P=0.003), lung collapse (90.0% vs. 41.7%, P=0.011) or linear fibrosis (70.0% vs. 30.6%, P=0.033) compared to those without recurrent symptoms.Bronchomalacia (OR =17.18; 95% CI,) and prior bronchoscopic airway resection (OR =4.97; 95% CI, 1.20-20.60) were strongly associated with the recurrence of symptoms or need for repeat airway intervention on multivariate logistic regression analysis. Conclusions: Bronchomalacia and prior bronchoscopic airway resection are associated with the recurrence of symptoms despite airway intervention. Patients who are diagnosed with TSTB early in the course of active TB may be conservatively managed.

Intraoperative colonic irrigation followed by one-stage resection is gaining popularity as the optimal surgical treatment for left-sided colonic obstruction. However, its efficacy and potential hazards have not been adequately tested in obstruction due to colonic cancer. We analyzed the early results of 23 consecutive patients with obstructive left-sided colonic carcinoma treated by primary resection and anastomosis following intraoperative antegrade colonic lavage. Two patients (8.6%) died, one from complication of anastomotic leakage. The significant postoperative complications were chest infection in three (13%) and wound infection in seven (30.4%). The average hospital stay was 16.5 days. The results of this study suggest that intraoperative bowel irrigation permits one-stage resection and anastomosis to be conducted with reasonable safety provided care is taken in operative techniques.

Safe, if there is no alternative

A middle-aged woman presented with symptoms suggestive of allergic asthma but with markedly elevated peripheral eosinophilia. She did not respond to inhaled corticosteroids, thereby prompting further investigations. Chest radiograph was normal. CT of the chest revealed bi-apical ground glass opacities. Bronchoalveolar lavage revealed predominantly eosinophilic yield. Autoimmune screen was negative. Bone marrow biopsy showed a normocellular marrow with increased eosinophils. A diagnosis of chronic eosinophilic pneumonia (CEP) was made after exclusion of other causes of eosinophilia. Treatment of her CEP with systemic corticosteroids (prednisolone 0.5 mg/kg/day) resulted in dramatic improvement in symptoms and peripheral eosinophilia.

A retrospective analysis of the treatment of 70 patients with obstructed left colonic cancer was undertaken in order to assess whether staged or primary resection was more appropriate. Thirty‐four patients had initial colostomy and staged resection (group 1) while 36 patients were treated by primary resection and immediate anastomosis following intra‐operative bowel washout (group 2). There were seven deaths (10%), five in group 1 and two in group 2. The wound infection rate and average hospital stay were 44% and 36 days in group l and 19.4% and 16.5 days in group 2, respectively. Twenty per cent of patients in group 1 did not complete their staged procedures and had to live with their colostomies. The smoother postoperative recovery and shorter hospital stay was particularly significant in group 2 patients. As primary resection and anastomosis can now be performed with relative safety and reduced morbidity, we conclude that staged procedures can no longer be accepted as standard treatment for left colonic obstruction.
