Evaluation and treatment of gastric stimulator failure in patients with gastroparesis.

OBJECTIVE: This study evaluates treatment of gastroparesis patients refractory to gastric electrical stimulation (GES) therapy with surgical replacement of the entire GES system. SUMMARY BACKGROUND DATA: Some patients who have symptomatic improvement with GES later develop recurrent symptoms. Some patients improve by simply altering pulse parameter settings. Others continue to have symptoms with maximized pulse parameters. For these patients, we have shown that surgical implantation of a new device and leads at a different gastric location will improve symptoms of gastroparesis. METHODS: This study evaluates 15 patients with recurrent symptoms after initial GES therapy who subsequently received a second GES system. Positive response to GES replacement therapy is evaluated by symptoms scores for vomiting, nausea, epigastric pain, early satiety, and bloating using a modified Likert score system, 0 to 4. RESULTS: Total symptom scores improved for 12 of 15 patients with GES replacement surgery. Total score for the replacement group decreased from 17.3 ± 1.6 to 13.6 ± 3.7 with a difference of 3.6 (P value = .017). This score is compared with that of the control group with a preoperative symptom score of 15.8 ± 3.6 and postoperative score of 12.3 ± 3.5 with a difference of 3.5 (P value = .011). The control group showed a 20.3% decrease in mean total symptoms score, whereas the study group showed a 22.5% decrease in mean with an absolute reduction of 2.2. CONCLUSION: Reimplantation of a GES at a new gastric location should be considered a viable option for patients who have initially failed GES therapy for gastroparesis.

Predictable closure of the abdominoperineal resection defect: a novel two-team approach.

BACKGROUND: Primary closure of the perineum at the time of abdominoperineal resection (APR) is seldom successful. Several factors are known to adversely affect healing, including neoadjuvant chemoradiation, tension, contamination, and fluid collection. This study evaluates a 2-team approach for resection and routine perineal closure in a single stage. STUDY DESIGN: After tumor resection, the abdominal and perineal closures are performed simultaneously by 2 separate teams. A competent closure of the perineal defect is achieved with bilateral V-to-Y inferior gluteal artery perforator fasciocutaneous flaps (BIGAP) mobilizing buttock skin, fat, and gluteal muscle fascia for inset into the defect. No muscle is elevated with the flaps and no attempt is made to obliterate the deepest aspects of the pelvic defect. RESULTS: Beginning in August 2010, 18 consecutive patients who underwent APR for distal rectal (n = 14) and anal carcinoma (n = 4) were included in the study. All patients had received neoadjuvant chemoradiation therapy. Primary healing was achieved in 16 of 18 patients with a completely tension-free closure. One patient required debridement and secondary closure. Another patient had an unresectable tumor, which invaded the flap closure. Minor healing problems were seen in 7 patients. CONCLUSIONS: BIGAP flaps provide sufficient tissue to predictably provide primary closure of the perineal defect. Perineal wound healing morbidity is dramatically reduced compared with primary simple closure of this defect. Early results indicate that this method of perineal closure offers a straightforward and predictable method that is comparable in efficacy to other methods using pedicled flaps for perineal closure.
