Analysis of risk factors for postpneumonectomy bronchopleural fistulas in patients with lung cancer.
Bronchopleural fistula is a potentially fatal complication of pulmonary resections, especially pneumonectomy. ⋯ Bronchopleural fistula is strongly associated with preoperative infection, right pneumonectomy, and pathological N2, 3 disease. Bronchial stump coverage with pedicled tissue flaps and preservation of the bronchial arteries during mediastinal lymph node dissection are recommended to maintain the blood supply to the bronchial stump in patients at risk.

With the increasingly widespread acceptance of laparoscopic cholecystectomy (LC), the number of cases of incidental gallbladder carcinoma (GBC) has increased; however, management of incidental GBC is a difficult issue in the absence of established guidelines. The present study aims to evaluate the treatment of patients with incidental GBC diagnosed with LC. We performed a 14-year review of 10 patients with GBC discovered with LC. ⋯ For stage Tis or T1a tumors, LC is sufficient. Patients with T1b tumors should undergo liver-bed resection and lymphadenectomy, and patients with >pT2 tumors should undergo systematic liver resection with lymphadenectomy. Even when incidental GBC diagnosed with LC is advanced, adequate additional surgery may improve the prognosis.

While reassessing the value of exfoliative cytologic examination of prostatic fluid (PF) for the diagnosis of prostate cancer, we found that PF is easily obtained with transrectal ultrasonography during prostate biopsy and that cytologic examination of PF is useful for the diagnosis of prostate cancer. ⋯ Exfoliative cytologic examination of PF is a valuable, noninvasive method for detecting prostate cancer, especially in patients with high PSA levels.

Randomized Controlled Trial
An epidural initial dose is unnecessary in combined spinal epidural anesthesia for Caesarean section.
Combined spinal epidural anesthesia is widely used for Caesarean section. Bolus administration of an epidural initial dose introduces the risk of drug flux from the epidural space to the subarachnoid space, and the volume effect of the initial dose may cause epidural top-up and extension of subarachnoid blockade. These problems may be avoided if the initial dose is not administered. ⋯ Between the initial dose group and the continuous group, there was no significant difference in the number of times flurbiprofen or pentazocine were used for postoperative pain relief. However, the number of times that pentazocine was used was significantly higher in the spinal group than in other groups. This finding suggests that an epidural initial dose is unnecessary for postoperative pain relief in combined spinal epidural anesthesia for Caesarean section.

Floating right heart thrombi (FRHTs) are rare in patients with acute pulmonary thromboembolism (PTE). FRHTs are an extreme therapeutic emergency, and any delay in treatment could be lethal. Heparin, thrombolysis, and catheter therapy are used most frequently to treat acute PTE. ⋯ Thromboembolectomy was performed on cardiopulmonary bypass. One patient became brain dead 10 days postoperatively owing to cardiopulmonary arrest before surgery. The two survivors were subsequently discharged home after uneventful recoveries.
