RESUMEN

Standard treatment modalities of caliceal diverticular calculi range from extracorporal shockwave lithotripsy (SWL) over retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PNL) and laparoscopic stone removal. A 55-year-old woman presented with a history of pyelonephritis based on a caliceal diverticular calculus. Due to the narrow infundibulum and anterior location, a robot-assisted laparoscopic calicotomy with extraction of the calculi and fulguration of the diverticulum was performed, with no specific perioperative problems and good stone-free results. This article shows technical feasibility with minimal morbidity of robot-assisted laparoscopic stone removal and obliteration of a caliceal diverticulum.

RESUMEN

INTRODUCTION AND HYPOTHESIS: The value of a repeat mid-urethral sling (MUS) after a failed primary sling is not generally accepted. We hypothesize that repeat MUS can be performed with favorable results and acceptable complication rates. METHODS: We reviewed the medical records of 80 women (mean age 62 ± 12.3 years) who underwent repeat MUS surgery from January 2000 to January 2009 at a single tertiary academic centre. Mean follow-up was 44.8 months (range 3-104). Three of these 80 patients were lost to follow-up. Twenty-six (33%) transobturator (TOT), 25 (31%) retropubic (TVT) and 16 (20%) minislings were placed as secondary slings. Thirteen slings (15%) were biological (Pelvicol™). In 4 patients (5%) a release of the primary sling was performed, and in 6 (7.5 %) the extruded sling fragment was totally excised prior to secondary sling placement. RESULTS: The overall subjective cure rate was 61.0%. Of the study group 74.0% reported subjective improvement. The amounts of pads reduced from a mean of 3.8 pads a day to a mean of 0.75 pads a day postoperatively. The objective cure rate was 63.5%. The incidence of de novo urgency was 8.2% (4 patients). When comparing different secondary sling types no difference was found in the overall continence rate, except for the biological sling. More than half (7 out of 13) of the patients from whom the secondary sling was a biological sling, were not satisfied (p=0.01). The subjective improvement rates in patients with recurrent or persistent stress urinary incontinence (SUI) were 68.2% and 75.0% respectively. This difference is not statistically significant (p=0.94). Excision versus release of the MUS showed a slightly higher satisfaction rate after excision, 84.6% and 74.0 % respectively (p=0.63). CONCLUSIONS: Cure rates and improvement rates of a repeat MUS are favorable and complication rates are acceptable. It should be offered to patients with persistent or recurrent SUI after a failed primary sling, even after previous release or excision.

RESUMEN

BACKGROUND: The Roux-en-Y gastric bypass (RYGB) performed laparoscopically (LRYGB) is the most frequently performed bariatric procedure in Belgium. However, late results in terms of weight loss or weight regain are inconsistent and may warrant a second procedure. This retrospective study analyzes the laparoscopic options for revisional surgery after LRYGB. METHODS: Between January 1, 2001 and December 31, 2009, 70 patients underwent a new laparoscopic procedure for poor weight loss or weight regain after LRYGB. The revisional procedure was performed a median of 2.6 years after the initial bypass operation. Fifty-eight patients were available for follow-up (82.9 %); 19 underwent distalization; and 39 a new restrictive procedure. RESULTS: The mean mass index (BMI) before the revisional procedure was 39.1 + 11.3 kg/m(2) (30.8-51.8), down from 42.7 + 19.7 kg/m(2) (33.0-56.6) initially, which corresponded to a percentage of excess weight loss (EWL) of 12.4 + 9.3 % (-1.0-29.1). After the corrective procedure, with a follow-up of approximately 4 years, mean BMI was 29.6 + 12.4 kg/m(2) (18.0-45.5), for a significant additional percentage of EWL of 53.7 + 9.8 % (2.0-65.8). The overall complication rate was 20.7 %, and the reoperation rate was 7.3 %. The overall leak rate was 12.1 %. Patients suffering from leaks could consistently be treated conservatively or by stent placement. Two patients needed reconversion after distal bypass. The satisfaction index was good in just over 50 % of the patients. CONCLUSION: Revisional laparoscopic surgery after RYGB performed for weight issues provides good additional weight loss but carries significant morbidity. Leaks can usually be handled non-surgically. Patient satisfaction is only fair.

RESUMEN

This retrospective study aimed to evaluate the long-term results of the laparoscopic Roux-en-Y gastric bypass (LRYGB) procedure performed at our department of bariatric surgery. The 126 consecutive patients treated by LRYGB between January 1, 2001 and December 31, 2002 were analyzed in August 2011. Seventy-seven patients (61.1 %), including 18 who had had previous bariatric surgery, were available for evaluation after 9.4 ± 0.6 years (range, 8.7-10.9 years). Eight patients (10.4 %) suffered from type 2 diabetes mellitus (DMII) at the time of surgery. Initial body mass index (BMI) was 40.3 ± 7.5 kg/m(2) (range, 24.5-66.1 kg/m(2)). There was no postoperative mortality, but two patients died of causes unrelated to the surgery. Some 9 % of the patients suffered from internal herniation, despite the closure of potential hernia sites. With time, the patients had the tendency to experience weight regain: percentage of excess BMI lost was 56.2 ± 29.3 % (range, -78.8 to 117.9 %), down from a maximum of 88.0 ± 29.6 % (range, -19.7 to 197.1 %), that had been obtained after a median of 2.0 years (range, 1-8 years). LRYGB was effective for diabetes control in 85.7 % of the affected patients, but, surprisingly, 27.9 % developed new-onset diabetes. The weight regain in this latter patient group was statistically not different from the nondiabetic group. Conversely, four patients required hospitalization for hypoglycemic syndrome. Two patients underwent reversal of their bypass for problems linked to glucose metabolism (one hypoglycemia, one DMII). Patient quality of life was fair. The patient satisfaction remained good in 76 % of the cases.
