Pancreatic Fistula after Pancreaticoduodenectomy: Diagnosed according to International Study Group Pancreatic Fistula (ISGPF) Definition

Aims: The aim of the study is to validate a new classification of pancreatic fistula (PF) and to document riskfactors for PR Methods: A retrospective study was performed on 100 patients who underwent pancreaticoduodenectomy (PD) within a 2-year period. PF was diagnosed according to the criteria developed by an International Study Group on Pancreatic Fistula (ISGPF). Sixteen pre- and intraoperative risk factors for PF were analyzed. Results: Of 100 patients 32 developed PF; grade A in 21 patients, grade B in 10, and grade C in 1. Four riskfactors including pathological diagnosis, concomitant surgery, diameter of pancreatic duct, and texture of the remnant pancreas were found to be significantly associated with PF by univariate analysis. Texture of the remnant pancreas and concomitant surgery were demonstrated to be independent risk factors by multivariate logistic regression. If a PF occurred, advanced age was found to be a risk factor for PF grade B by univariate analysis, but age was not an independent risk factor by multivariate logistic regression. Conclusions: The status of the remnant pancreas is identified as a substantial risk factor for PF after PD. When soft remnant pancreas is encountered, more careful handling is required in an attemptto minimize the rate of PF. This study confirms that the ISGPF classification of PF is useful.     

Impact of mediastinal lymph node dissection on octogenarians with non-small cell lung cancer

Objective: Impacts of mediastinal lymph node dissection on a patient’s course after pulmonary resection is unclear in octogenarians with non-small cell lung cancer. Methods: Retrospectively identified subjects included 39 octogenarians and 1 nonagenarian, with grades according to the Charlson Comorbidity Index ranging from only 0 to 2. We performed mediastinal lymph node dissection in 19 patients (D group), and just lymph node sampling biopsy in the other 21 (S group). We compared clinicopathologic features and outcome after surgery between both groups. Results: Deterioration of performance status at the time of discharge, evident in 17 patients overall, was significantly more frequent in the D group. Postoperative complications occurred in 27 patients overall and there was no significant difference between the two groups. Survival rates in younger patients at 1, 3, and 5 years were 86, 59, and 49%, respectively; in octogenarians these were 83, 58, and 42% (no significant difference). Nor did survival differ significantly by surgical management of mediastinal lymph nodes; 1-, 3-, and 5-year survival rates were 94, 63, and 40%, respectively in the D group and 78, 66, and 43%, respectively in the S group. Conclusion: Octogenarians with non-small cell lung cancer should be treated by urgent pulmonary resection whenever possible. Since mediastinal lymph node dissection has little effect on long-term survival or the carried risk of worsening performance status at discharge, pulmonary resection without complete mediastinal lymph node dissection should be considered.     

Intrapulmonary metastasis developing eighteen years after complete resection of thymoma

We present a case of intrapulmonary metastasis developing 18 years after complete resection of thymoma. An 8 mm nodule in the lower lobe of the left lung was noted on chest X-ray in a 76-year-old woman who had undergone complete resection of Masaoka’s stage II thymoma 18 years earlier. Since the nodule grew to 17 mm during a 2-year follow-up, wedge resection was performed. The lesion was histologically diagnosed as an intrapulmonary metastasis from thymoma. Extremely late recurrence after complete resection of thymoma is discussed.
