RESUMO
AIM: To assess the role of simple enucleation (SE) for the treatment of highly complex renal tumors. METHODS: Overall, 96 Preoperative Aspects and Dimensions Used for an Anatomical (PADUA) classification score 10 to 13 renal tumors were treated with SE at our institution. All conventional perioperative variables, surgical, functional and oncological results were gathered in a prospectively maintained database. Survival curves were generated using a Kaplan-Meier method. Univariate analysis assessed the outcome differences. RESULTS: Mean (± 1s.d.) clinical tumor diameter was 4.8 (± 1.6 cm). 70.8% of patients had ≥ cT1b stage. The PADUA score was recorded as 10, 11, 12 and 13 in 57.3%, 29.2%, 11.5%, and 2.1% of tumors respectively. Overall, 76 patients were treated with an open approach and 20 robotically. Mean warm ischemia time (WIT) was 19.2 min, and WIT greater than 25 min occurred in 14.6% of cases. Positive surgical margin (PSM) rate was 3.6% and trifecta was achieved in 64.3% of patients. Postoperative surgical complications occurred in 24% of patients, with 14.6% Clavien-Dindo grade 1-2, 8.3% grade 3, and 1% grade 4. Five-year cancer specific survival (CSS), recurrent free survival (RFS), and overall survival (OS) rates resulted 96.1%, 90.8% and 88.0%, respectively. Overall, 4.2% of patients experienced progressive disease. At follow-up, the mean decrease of eGFR from preoperative value was 13.9 ml/min. This was not significantly correlated with PADUA score (p = 0.69). The surgical approach was neither a predictor of Trifecta outcome, nor of postoperative complications, WIT > 25 min or PSM rate. CONCLUSIONS: SE is an effective treatment for highly-complex renal tumors, with a potential key role to widen the NSS (nephron sparing surgery) indications according to guidelines.

The gastrointestinal tract is the most common extranodal site of primary non-Hodgkin's lymphoma. We present a case of a 50-year-old male with primary B cell lymphoma arising in an S-pouch eight years after a total proctocolectomy for ulcerative colitis. After chemoradiotherapy the patient remained asymptomatic, with an intact S-pouch. Pouch conservation is feasible in patients with primary lymphoma of the pouch, using chemoradiotherapy and close follow-up examinations.

BACKGROUND: Morbid obesity contributes to many health risks, including physical, emotional, and social problems. Various surgical treatments for morbid obesity have developed and have so far met with good results. This study compares vertical banded gastroplasty (VBG) with gastric bypass (GBP) and the patients' satisfaction with either procedure. METHODS: Between April 1993 and July 1997, 63 bariatric surgical procedures were performed at Eisenhower Army Medical Center. Of those, complete follow-up was obtained for 29 patients. The parameters evaluated included age, preoperative and postoperative weights, body mass index (BMI), type of surgery, complications, and the patient's level of satisfaction. RESULTS: The study group consisted of 27 women and 2 men. The average preoperative weight was 135 kg, and the average preoperative BMI was 48.3 kg/m2. There were 17 VBGs and 12 GBPs performed. The average total weight loss was 45.1 kg. The average postoperative BMI was 33.2 kg/m2. There were no statistically significant differences in weight loss between VBG and GBP. Four of 17 patients had complications after VBG, and three of 12 patients had complications after GBP. After VBG, 94.1 % of patients were satisfied, and after GBP, 100% were satisfied. Twenty-seven of 28 patients stated that they would have the surgery again. CONCLUSION: There were no statistically significant differences in weight loss or complications after VBG or GBP. Patient satisfaction was high after both procedures. Therefore, bariatric surgery is important in the treatment of appropriately selected, morbidly obese patients.
