Differences in Post-Cholecystectomy Bile Duct Injury Care: A Comparative Analysis of 2 Different Health-Care Public Institutions in a Low- and Middle-Income Country: Southeast Mexico.

BACKGROUND: Mexican health system structure allows us to study the differences in bile duct injury (BDI) management. The study aimed to assess the differences in patients with complex BDI in 2 different public sector institutions using a new proposed standard terminology. METHODS: Retrospective review (2008-2019) in 2 public institutions (IMSS/SESVER). Bismuth-Strasberg E injuries with hepaticojejunostomy were included. Data are presented in a tabular reporting system. The outcomes were percent of patients attaining primary patency, loss of primary patency, and actuarial primary patency rate. RESULTS: Seventy-eight patients (IMSS: n = 37; SESVER: n = 41) without differences in demographic and preoperative assessment were studied. BDI occurred mostly in outside hospitals. Open cholecystectomy was the most common index operation in SESVER (73%, p = 0.02). IMSS had more surgeries (p = 0.007) and repair attempts (p = 0.06) prior to referral. Magnetic resonance cholangiopancreatography was more commonly used in IMSS patients. Biliary stents (45%) and cholangitis (29%) were more common in IMSS (p < 0.05). IMSS patients had longer follow-up than SESVER (p < 0.05). No differences in primary patency rates (IMSS: 89%, SESVER: 97%) and actuarial patency rates were noted. DISCUSSION: Despite differences in referral, preoperative, and operative events, good BDI repair outcomes can be achieved. Longer follow-up is needed to monitor these outcomes.

Successful Healing of Tracheal Radionecrosis: Role of Hyperbaric Oxygen Therapy.

Hyperbaric oxygen therapy, the administration of 100% oxygen at pressures > 1 atm, is believed to promote wound healing by increasing angiogenesis and collagen synthesis. To our knowledge, this treatment modality has never been described in patients with tracheal radionecrosis. Here, we report the case of a 55-year-old man diagnosed with stage IIIB lung adenocarcinoma who was treated with chemotherapy and concomitant external intensity-modulated radiotherapy involving the left lung and mediastinum. Nine months later, he presented with neck pain, cough with mucopurulent sputum, and fever. A PET-CT scan revealed a fissure in the posterior wall of the left upper trachea. Flexible bronchoscopy showed a tracheal ulceration with a small left posterior wall fissure that extended into the mediastinum. To our knowledge, this is the first report in the literature that suggests that treatment with hyperbaric oxygen therapy, local debridement, and antibiotics is a feasible and successful management option for patients with complicated tracheal radionecrosis.
