Introduction Complete cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is an effective treatment for improving prognosis of selected patients with peritoneal carcinomatosis. The addiction of diaphragmatic procedures may increase the incidence of postoperative respiratory complications. Our goal was to evaluate the early postoperative results following diaphragmatic surgery. Methods Prospectively collected data of patients undergoing diaphragmatic surgery between January 2000 and January 2020 were retrospectively analyzed. Chest drains were routinely placed in all cases. Demographics, clinical and perioperative features were evaluated. Results The study included 222 patients. Peritoneal stripping and full-thickness resections were performed in 165 and 57 cases, respectively. Women and ovarian tumours represented the vast majority of cases. Overall postoperative mortality and morbidity rates were 1.3% (3 patients) and 43.2% (96 patients), respectively. Specific diaphragmatic surgery-related complications was 9.4% (21 patients). No pleural effusion and pneumothotrax occurred. The incidence of pneumonia was 1.8% (4 patients), each due to systemic bacterial origin, 2 (0.9%) of which required Intensive Care Unit-readmission. Postoperative bleeding was observed in 15 (6.7%) cases, 12 (5.4%) of which required reoperation. A comparison with 105 patients who operated during the same period without diaphragmatic surgery was performed and by multivariate analysis, Peritoneal Cancer Index, histology and overall morbidity resulted significantly associated with diaphragmatic surgery. Conclusion Diaphragmatic surgery during cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is often required in order to obtain complete resection. It may be associated with higher postoperative morbidity, especially bleeding, but routine placement of chest drains may reduce the incidence of adverse respiratory events.

We hereby present the case of a 55-year-old woman with an iatrogenic tracheal laceration that occurred during double lumen intubation for left pneumonectomy. Conservative treatment was performed and the patient was discharged 12 days after surgery. No major sequelae after 3 months of follow-up were observed.

Long-term immunoprophylaxis with anti-HBs immunoglobulins (HBIg) is used to prevent hepatitis B (HBV) reinfection after liver transplantation for HBV-related cirrhosis. This approach is highly expensive. A recent report proposed posttransplant HBV vaccination with a reinforced schedule as an alternative strategy to allow HBIg discontinuation. We investigated the efficacy of a reinforced triple course of HBV vaccination in 17 patients transplanted for HBsAg-positive cirrhosis 2 to 7 years earlier. The first cycle consisted of 3 double intramuscular doses (40 microg) of recombinant vaccine at month 0, 1, and 2, respectively. This was followed, in nonresponders, by a second cycle of 6 intradermal 10 microg doses every 15 days. All nonresponders then received a third cycle identical to the first one. Vaccination started 4.5 months after HBIg discontinuation, and lamivudine (100 mg/day) was given throughout the study. All patients were seronegative for HBsAg and HBV-DNA (by PCR) and positive for anti-HBe, and 7 were positive for anti-HDV. After the first cycle one patient (#5, 53 years old, male) developed an anti-HBs titer of 154 IU/L, another (#12) reached a titer of 20 IU/L and the remainder had titers10 IU/L. At month 7, patient #5 reached a titer of 687 IU/L. After the second cycle only one additional patient (#9) had a slight response (an anti-HBs titer of 37 IU/L). After the third cycle patient #9 rose to an anti-HBs titer of 280 IU/L, patient #12 dropped to 10 IU/L, and no other patient responded. In conclusion, a highly reinforced HBV vaccination program is effective only in a few patients who had liver transplants for HBV-related cirrhosis.
