Comparative study between open and minimally invasive approach in the surgical management of esophageal leiomyoma.

INTRODUCTION: Leiomyomas are the most common benign tumors of the esophagus. Although classically surgical enucleation through thoracotomy or laparotomy has been widely accepted as treatment of choice, development of endoscopic and minimally invasive procedures has completely changed the surgical management of these tumors. MATERIAL AND METHODS: We performed a retrospective review of all esophageal leiomyoma operated at Hospital Universitario Ramón y Cajal (Madrid, Spain) between January 1986 and December 2014, analyzing patients' demographic data, symptomatology, tumor size and location, diagnostic tests, surgical data, complications and postoperative stay. RESULTS: Thirteen patients were found within that period, 8 men and 5 women, with a mean age of 53.62 years (range 35-70 years). Surgical enucleation was achieved in all patients. In 8 cases (61.54%) a thoracic approach was performed (4 thoracotomies and 4 thoracoscopies), and in 5 cases (38.56%) an abdominal approach was performed (3 laparotomies and 2 laparoscopies); enucleation was carried out through a minimally invasive approach in 6 patients (46.15%). There were no cases of endoscopic resection alone. Surgery mean length was 174.38 minutes (range 70-270 minutes) and median postoperative stay was 6.5 days (range 2-27 days). There was neither mortality nor cases of intraoperative complications were described. No postoperative major complications were reported; however one patient presented important pain in his right hemithorax that required management and long term follow-up by the Pain Management Unit. With a mean follow-up of 165.57 months (median 170; range 29-336 months) no recurrences were reported. CONCLUSION: Enucleation is the treatment of choice for the majority of esophageal leiomyomas. In our experience, duration of the surgical procedure through minimally invasive approach was longer than surgery through open approach; however, postoperative stay was shorter in the first group. Paradoxically, incision pain after surgery (thoracic neuralgia) was found to be higher in the minimally invasive approach group. Nevertheless, none of the results obtained in the study reached statistical significance, probably due to the small simple size.

Duodenal fistula after gastrectomy: Retrospective study of 13 new cases.

INTRODUCTION: Duodenal stump fistula (DSF) after gastrectomy has a low incidence but a high morbidity and mortality, and is therefore one of the most aggressive and feared complications of this procedure. MATERIAL AND METHODS: We retrospectively evaluated all DSF occurred at our hospital after carrying out a gastrectomy for gastric cancer, between January 1997 and December 2014. We analyzed demographic, oncologic, and surgical variables, and the evolution in terms of morbidity, mortality and hospital stay. RESULTS: In the period covered in this study, we performed 666 gastrectomies and observed DSF in 13 patients (1.95%). In 8 of the 13 patients (61.5%) surgery was the treatment of choice and in 5 cases (38.5%) conservative treatment was carried out. Postoperative mortality associated with DSF was 46.2% (6 cases). In the surgical group, 3 patients developed severe sepsis with multiple organ failure, 2 patients presented a major hematemesis which required endoscopic haemostasis, 1 patient had an evisceration and another presented a subphrenic abscess requiring percutaneous drainage. Six patients (75%) died despite surgery, with 3 deaths in the first 24 hours of postoperative care. The 2 patients who survived after the second surgical procedure had a hospital stay of 45 and 84 days respectively. In the conservative treatment group the cure rate was 100% with no significant complications and an average postoperative hospital stay of 39.5 days (range, 26-65 days). CONCLUSION: FMD is an unusual complication but it is associated with a high morbidity and mortality. In our experience, conservative management has shown better results compared with surgical treatment.

[Effect of educational support on treatment adherence in patients with type 2 diabetes: an experimental study]. / Efecto del apoyo educativo para la adherencia al tratamiento en pacientes con diabetes tipo 2: un estudio experimental.

INTRODUCTION: Adherence to pharmacological or non-pharmacological treatment of diabetes type 2 is fundamental in order to delay the onset of complications. OBJECTIVE: To measure the effect of nursing educational support on compliance with treatment in patients with type 2 diabetes attending Regional Hospital Universitario of Colima, Mexico. METHOD: An experimental, randomized study including outpatients with type 2 diabetes attending a Regional Hospital who agreed in writing to participate in the study. Nursing educational intervention sessions of three hours on two days a week for three months were provided. Adherence to treatment was assessed before and after intervention using the Scale for treatment adherence in type 2 diabetes (EATDM-III(©)). STATISTICAL ANALYSIS: We performed two-proportion Z and p; Risk Ratio and confidence interval 95% and attributable fraction exposed. RESULTS: e experimental group had 32 members, the same as the control. After the intervention it was found that 16 members (50%) in the experimental group showed treatment adherence, unlike the control group where no one showed adherence to treatment, obtaining an independent two-proportion Z=4.62, P=.0000, Risk Ratio=65; Confidence Interval 95%=3.67 to 1152.38; exposed attributable fraction=98.46%. CONCLUSION: The intervention was effective for the adherence of treatment.
