ABSTRACT
analysis on 103 cases of spontaneous pneumothorax patients between September, 2012 and December,2014. Then the patients were randomly divided into two groups according to the different therapies on pulmonary bulla, 52 in GIA surgical stapler group and 51 in ligature group. Comparison: The postoperative situations of the two groups.Results: The operation time and intraoperative bleeding volume of observation group are obvious less than control group(t=7.58,t=16.87;P<0.01), but oxygen saturation of observation group is obvious higher than control group(t=1.34,P<0.01). The operation fee of observation group is obvious higher than control group(t=38.26, P<0.01).2 cases of postoperative recurrence in observation group(3.84%), but 10 cases in control group(19.60%).The two recurrence rates have statistical significance(x2=4.77,P<0.05). The postoperative complications incidence is 5.77% in observation group,but 21.56% in control group.The two The postoperative complications incidences have statistical significance(x2=5.47,P<0.05).Conclusion: As opposed to ligature, under the therapy for spontaneous pneumothorax with GIA surgical stapler by thoracoscopy, the operation time is shorter, intraoperative bleeding volume is less, and recurrence rate is lower in 2 years. Ligature fits the sporadic pulmonary bulla patients.
ABSTRACT
RACIONAL: A ruptura da linha de grampos representa grave problema em operações gastrointestinais. Reforçar o grampeamento com sobressutura ou dispositivos biológicos é assunto controverso. OBJETIVO: Comparar a pressão de ruptura do grampeamento simples, com grampeamento com sobressutura e com grampeamento com Surgisis®. MÉTODO: Em um suíno anestesiado, foram criados dez segmentos intestinais com cada tipo de grampeamento. Esses segmentos foram insuflados até que rompessem e a pressão de ruptura foi medida para posterior comparação. RESULTADO: A pressão de ruptura da linha de grampeamento foi de 94 mmHg +/- 18,52mmHg no grupo do grampeamento simples; 87,5 mmHg +/- 18,59 mmHg no grupo de grampeamento com sobressutura; e 83,33mmHg +/- 23,04 mmHg no grupo de grampeamento com Surgisis®. Não houve diferença estatística entre os grupos. CONCLUSÕES: O reforço do grampeamento com sobressutura ou aplicação de Surgisis® não aumenta a resistência da linha de grampos em suíno.
BACKGROUND: Staple line leaks carry significant morbidity and mortality. Reinforcement is controversial. Several staple techniques have been described for this purpose. Oversuture and butressing material are more common. AIM: To compare these two ways of reinforcement and staple line without any reinforcement regarding the bursting pressure. METHOD: Ten segments of small bowel were created in a pig under general anesthesia. The bowel was inflatted until burst point and the pressure was measured. RESULTS: The staple line bursting pressure was 94 mmHg +/- 18,52mmHg in the stapler technique; 87,5 mmHg +/- 18,59mmHg in the oversuture and 83,33 mmHg +/- 23,04mmHg with Surgisis®. There was no statistic difference among the techniques. CONCLUSIONS: Oversuture or Surgisis® use did not increase the staple line resistance in pig.

RACIONAL: O divertículo faringoesofágico apresenta-se como distúrbio pouco frequente e é provável que este fato seja responsável pela dificuldade encontrada na escolha do método terapêutico mais eficaz. O tratamento cirúrgico ainda é a principal opção terapêutica. No entanto, há controvérsias quanto à técnica cirúrgica que garante melhores resultados. OBJETIVO - Avaliar a eficácia da diverticulectomia com miotomia do músculo cricofaríngeo pela sutura mecânica linear no tratamento cirúrgico do divertículo faringoesofágico em uma série de pacientes no tocante às suas complicações locais e sistêmicas. MÉTODO: Foram atendidos 19 pacientes com divertículo de Zenker. Todos apresentavam as condições clínicas necessárias e preenchiam os critérios de elegibilidade para realização do procedimento cirúrgico. Após a diverticulectomia com sutura mecânica todos foram submetidos a avaliação pós-operatória no sentido de identificar a manifestação de qualquer tipo de complicação. Os pacientes foram estudados retrospectivamente através da análise de prontuários e descrição da internação hospitalar realizada no momento da operação e da evolução ambulatorial. RESULTADOS: A totalidade apresentou resultados satisfatórios, sem evidência de fístula ao nível da sutura da faringe no período pós-operatório precoce. Somente dois indivíduos perderam seguimento na avaliação tardia e um desenvolveu estenose faríngea revertida com dilatação endoscópica. Todos referiram estar satisfeitos com o procedimento empregado e relataram melhora na qualidade de vida ao final do seguimento, proporcionada pelo retorno da deglutição. CONCLUSÃO: A diverticulectomia com a miotomia do músculo cricofaríngeo e posterior fechamento da faringe com sutura mecânica linear mostrou-se técnica eficaz, com poucas complicações pós-operatórias e melhora significativa na qualidade de vida.
BACKGROUND: Pharyngoesophageal diverticulum presents itself as an uncommon disorder. Thus, choosing the most effective treatment method may be challenging. Surgical treatment remains as the main option. However, establishing the best surgical technique is still controversial. AIM: To evaluate the results of diverticulecomy with chricopharyngeal miotomy and linear stapler closure of the pharynx in a patient sample with Zenker`s diverticulum regarding local and systemic complications. METHODS: Nineteen patients with pharyngoesophageal diverticulum were admitted. All of them presented the clinical conditions required to indicate the surgical procedure. Patients were evaluated with regard to any post-operative complications. This study was conducted retrospectively with patients' data analysis. RESULTS - Patients showed satisfactory results, with no evidence of fistula at the level of the pharyngeal suture. Two out of 19 lost post-operative follow-up and one of them had pharyngeal stenosis reverted with endoscopic dilation. The entire sample reported being satisfied with the procedure emphasizing improvement of the quality of life mainly due to the return of physiological deglutition. CONCLUSION: The diverticulectomy with myotomy and posterior pharyngeal closure with linear surgical stapler proved to be an effective technique, offering a lower risk of post-operative complications and improving the overall quality of life.

BACKGROUND: Staple closure of bronchial stump was compared with manual suture closure among 100 cases of pneumonectomy during the recent 5-year period. We have reviewed the incidence of bronchpleural fistula between autosutured group and manual sutured group. MATERIAL AND METHOD: During the recent 5-year period, 100 patients underwent pneumonectomy at Hanyang University Hospital. Staple closure of bronchial stump was performed in 65 patients and manual suture in 35 patients. There were 55 males and 10 females in the autosutured group, and 26 males and 9 females in manual sutured group, which showed no significant statistical difference between the two groups. The mean ages of patients for autosutured group and manual sutured group were 56.7+/-10.3 years and 61.4+/-9.2 years, respectively, which showed no significant statistical difference between the two groups. There were 38 cases of left pneumonectomy and 27 cases of right pneumonectomy in autosutured group, and 22 cases of left pneumonectomy and 13 cases of right pneumonectomy in manual sutured group. There were 53 cases of malignancy and 12 cases of benign imflammatory disease in autosutured group, and 27 cases of malignancy and 7 cases of benign imflammatory disease in manual sutured group. RESULT: The incidence of bronchopleural fistula was 6.1% in autosutured group and 5.7% in manual sutured group. The incidence of other postoperative complication between the two groups showed no significant statistical difference. CONCLUSION: The incidence of bronchopleural fistula between autosutured group and manual sutured group was not different stastically. Both method for closure of bronchial stump can be performed in pneumonectomy.

BACKGROUND: The use of the stapler n esophageal reconstruction after esophageal resection for benign or malignant esophageal diseases has become popular because it has less leakage at the anastomotic site and shorter operation time than manual sutures. However, the use of classic circular stapler has some complications such as stenosis and dysphagia that requires additional treatment. Such complications are closely related to the inner diameter of the anastomotic sites. In this study, the diameter of anastomotic site was compared after the use of circular stapler(EEA) and straight endoscopic stapler(endo GIA). MATERIAL AND METHOD: The patients who received esophageal reconstruction by stapler from August 1995 to September 1997 were reviewed. The patients were divided into 2 groups. One group need the circular stapler, and the other group the straight endo GIA(14 cases with endo GIA 30mm, 24 with endo GIA 45mm). After a cervical esophago-enteric anastomosis, the stricture of anastomotic site and the incidence of dysphagia were compared between the 2 groups using an esophagography and the patient's symptoms. The follow-up period was 12months in average. RESULT: In the former group in which the circular stapler was used, 2 cases of anastomotic stenosis were reported. In comparison, none were reported in the latter group. Dysphagia were reported in 8 cases of the former group, and in 3 cases of the latter group(1 case in endo GIA 30 mm, 2 cases in endo GIA 45 mm). CONCLUSION: The use of endo GIA in esophago-enteric anastomosis resulted in a wider diameter of the anastomotic site, lesser stricture, and lesser incidence of dysphagia compared to the use of former circular stapler. Therefore, it is thought to be a better method in esophageal reconstructions.

The surgical stapling technique has been recognized as an indispensable tool in rectal cancer surgery. A personal experience in one-hundred patiens is presented for the purpose of appropriate use of the surgical staplers. Three anastomotic techniques used were end-to-end anastomosis in 75 cases, double-stapling in 11 cases, and side-to-end anastomosis in 14 cases. In 88 cases, level of anastomosis was below the peritoneal reflection. Eight cases of stapling errors were found during operation. Among them, 5 cases of instrumental failure were 2 cases of blade defect and each one of difficult extraction, misfiring or tearing over trocar. The other 3 cases of surgical errors come from uneven perirectal excision causing one incomplete doughnut and 2 deficient anastomosis. Distal resection margin was closely related to the location of tumor(p < 0.01), but local recurrence did not associated with it. Two cases of postoperative hematochezia showed self-limiting. Anastomotic leakage occurred in 3 female patients and they were converted into resection. Excluding one leakage from skipped proximal foci, 2 cases occurred in the ultra-low anastomosis. Postoperative stricture was found in 5 cases and they were not associated with internal diameter of circular stapler. They were treated by manual dilatation and bulk-forming laxatives without surgical intervention. Bowel frequency or inability of deferrment was found in 9 cases on 1 month and 5 cases on 6 months postoperatively. They were not related to anastomotic level or stapling method. In conclusion, the stapling technique in rectal cancer surgery is a safe as well as a comfortable technique whenever complication can be amenable to the surgeon.
