ABSTRACT

BACKGROUND: Approximately 20-30 % of patients who undergo Roux-en-Y gastric bypass (RYGB) will not meet the goals of weight loss surgery. Revisional surgery is associated with higher morbidity compared to initial operative management, and results in terms of weight loss have been inconsistent. Endoscopic plication has been seen as a less invasive option, with encouraging initial results. The objective was to analyze the outcomes after Restorative Obesity Surgery, Endolumenal (ROSE) procedure. METHODS: We retrospectively analyzed patients who underwent ROSE between 5/2008 and 11/2013. All patients had failure of weight loss or regain weight after RYGB. Demographics, operative data, and follow-up were recorded. RESULTS: Twenty-seven patients underwent ROSE. One patient was excluded due to lack of follow-up. Twenty-five (96 %) patients were female. Mean time since initial RYGB was 11.9 ± 4.3 years. Mean initial weight and BMI were 236 ± 47 lb and 40.6 ± 8.1 kg/m(2), respectively. Mean OR time was 77 ± 30 min. Preoperative average pouch length and stoma diameter were 6.8 ± 2.3 and 2.1 ± 0.7 cm, respectively. On average, 4 ± 1.6 stitches were placed. Final pouch length and stoma diameter were 3.4 ± 1.6 (50 % reduction) and 0.86 ± 0.4 cm (61 % reduction). A total of 12 (46 %) and seven (28 %) patients underwent EGD at 3 and 12 months postoperatively. The mean pouch length and stoma diameter were 5 ± 1.9 (26.5 % reduction) and 1.2 ± 0.7 cm (42.9 % reduction) at 3 months and 6.14 ± 1.6 (10 % reduction) and 2.2 ± 1.2 cm (4.7 % increase) at 12 months, respectively. The %EWL was 8.9, 9.3, 8, 6.7, -10.7, -13.5, -5.8, -4.5 at 3, 6, 12, 24, 36, 48, 60, and 72 months, respectively. CONCLUSION: Although endoscopic plication achieved the intended reduction in the pouch and stoma diameter at 3 months, these tend toward the preoperative diameter at 12 months. This anatomical failure and the lack of follow-up may explain why most patients failed to achieve sustainable weight loss.

ABSTRACT

BACKGROUND: Laparoscopic and endoluminal surgical techniques have evolved and allowed improvements in the methods for treating benign and malignant gastrointestinal diseases. To date, only case reports have been reported on the application of a laparo-endoscopic approach for resecting gastric submucosal tumors (SMT). In this study, we aimed to evaluate the efficacy, safety, and oncologic outcomes of a laparo-endoscopic transgastric approach to resect tumors that would traditionally require either a laparoscopic or open surgical approach. Herein, we present the largest single institution series utilizing this technique for the resection of gastric SMT in North America. METHODS: We performed a retrospective review of a prospectively collected patient database. Patients who presented for evaluation of gastric SMT were offered this surgical procedure and informed consents were obtained for participation in the study. RESULTS: Fourteen patients were included in this study between August/2010 and January/2013. Eight (8) patients (57.1 %) were female and the median age was 56 years (range 29-78). Of the 14 cases, 8 patients (57.1 %) underwent laparo-endoscopic resection of SMTs with transgastric extraction, 5 patients (35.7 %) had conversions to traditional laparoscopic surgery, and 1 patient (7.2 %) was abandoned intraoperatively. The median operative time for this cohort was 80 min (range 35-167). Ten patients (71.4 %) had GISTs, 3 (21.4 %) had leiomyomas, and 1 (7.1 %) had schwannoma. There were no intraoperative complications. Two patients had postoperative staple line bleeding that required repeat endoscopy. The median hospital stay was 1 day (range 1-6) and there were no postoperative mortalities. At 12-month follow-up visit, only one GIST patient (10 %) had tumor recurrence. CONCLUSION: Our experience suggests that this surgical approach is safe and efficient in the resection of gastric SMT with transgastric extraction. This study found no intraoperative complications and optimal oncologic outcomes during the follow-up period. Minimally invasive surgical approaches are emerging as a valid and potentially better approach for resecting malignancies; however, continued investigation is underway to further validate this data.
