ABSTRACT
Objective To assess the value of video-assisted thoracoscopic mini-invasive lobectomy in the treatment of pulmonary benign lesions or malignancies. Methods A retrospectively analysis on clinical data of 35 cases of video-assisted thoracoscopic mini-invasive lobectomy, which were performed from February 2002 to June 2006, was made. The pathological diagnosis included 31 cases of peripheral lung cancer (T_1N_0-1M_0), 3 cases of bronchiectasis, and 1 case of atelectasis combined with pulmonary abscess. The procedures included 30 cases of anatomical lobectomy and 5 cases of non-anatomical lobectomy. Results No conversion to open surgery was required. The operation time was 85~210 min (115?35 min) and the intraoperative blood loss was 150~450 ml (210?55 ml). Postoperatively, acute respiratory failure was encountered in 2 cases, and mechanical ventilation was given for 3 and 5 days, respectively. Acute myocardial infarction occurred in 1 case, which was cured by early-stage thrombolysis. No postoperative complications were seen in the remaining 32 cases. The closed chest drainage was maintained for 2~10 days (mean, 5.4 days). In 3 cases of pulmonary benign lesions, follow-up checkups for 41, 33, and 13 months, respectively, found no long-term complications. In 25 cases of lung cancer, follow-up observations were made for 3~53 months (mean, 15.2 months), including 3~12 month in 6 cases, 12~24 months in 9 cases, 24~36 months in 7 cases, and 36~53 months in 3 cases. There were 4 cases of death due to cancer recurrence or metastasis (16%), 2 cases of with-tumor survival (8%), and 19 cases of disease-free survival (76%), respectively. Conclusions Video-assisted thoracoscopic mini-invasive lobectomy is a feasible and safe procedure for peripheral lung cancer and benign lung diseases.
ABSTRACT
Two cases of incomplete regression of ventral mesogastrium were reported. Their nomenclature, etiology, symptoms and characteristic roentgenologic findings were discussed in relation to anatomical study. Because of its unique etiology and symptoms, charecteristic roentgenologic findings, and effectual remedy, it is suggested that this disease should be distinguished from "abnormal adhesion of fibrous bands" as an independent anomaly called incomplete regression of ventral mesogastrium. The roentgenological findings were: An incisure was found in the upper portion of pars descendens duodeni. It sank deeply and reduced two thirds of the normal diameter of the intestinal lumen to form an eccentrie intestinal stenosis. The intestinal lumen, near the inner border of the incisure was smooth, and there was no sign of serrated image formed by intestinal mucosa. The part of intestinal lumen was not distended in hypotonic radiography. All the above signs were caused by the traction and binding of the nonregressed mesogastrium.
