Roux-en-Y gastric by-pass (RYGB) is one of the most effective bariatric procedures, but the rate of weight regain (WR) can reach 63% after the second year. Enlargement of the gastrojejunal anastomosis is one of the reported causes. A newly CE-marked flexible endoscopic system, Bariatric Anastomotic Reduction System (BARS) (Ovesco Endoscopy, Tuebingen, Germany), derivative of the well-established endoscopic over-the-scope-clip (OTSC) clipping system, has been recently developed. It was tested in pre-clinical and preliminary clinical use for feasibility and effectiveness in bariatric anastomotic reduction. Using a single-channel endoscope with external supplemental working channel, the BARS device captures the two limbs of the anastomosis, reducing its size, thus slowing food passage. After preclinical assessment, six patients with at least a 15% WR and the presence of an enlarged gastrojejunostomy > 20 mm were enrolled. The mean patient age was 49 years (range 24–67). Average interval between gastric bypass and BARS procedure: 8 years (4–13). All procedures were safely performed without complications. Mean procedure time: 52 min (37 − 75). Preliminary results: mean weight loss 6 kg (4–9) at a 3-month FU. BARS could be a promising endoscopic system in case of WR after gastric bypass due to enlargement of the anastomosis.

Background: Laparoscopic adjustable gastric banding (LAGB) has proven to be a safe and effective surgical treatment for morbid obesity. It can be a simple, fast, reversible, anatomy-preserving procedure. Despite these advantages, its long-term efficacy came into question by the occurrence of complications such as intragastric band migration. Consistent information regarding this complication is still lacking. Treatment for migration is still being debated as well. Most of the inconsistencies of these data stem from the very low number of patients reported in single-center experiences or case reports. Lack of multicenter experience is evident. The aim of this study was to perform a retrospective analysis of data on intragastric migration in a large multicenter cohort of patients who underwent LAGB. Methods: A retrospective multicenter study on LAGB patients was performed. Data had been entered into a prospective database of the Italian Group for LapBand (GILB) since January 1997. Pars flaccida and perigastric positioning were considered along with different kinds of gastric bands by the same manufacturer. Time of diagnosis, mean body mass index (BMI), presentation symptoms, and conservative and surgical therapy of intragastric migration were considered. Results: From January 1997 to December 2009, a total of 6,839 patients underwent LAGB and their data were recorded [5,660 females, 1,179 males; mean age 38.5 ± 18.2 years (range 21-62 years); mean BMI = 46.7 ± 7.7 kg/m (range 37.3-68.3); excess weight (EW) 61.8 ± 25.4 kg (range 36-130); %EW 91.1 ± 32.4 % (range 21-112 %)]. A total of 177 of 6,839 (2.5 %) intragastric erosions were observed. According to the postoperative time of follow-up, the diagnosis of intragastric migration was made in 74 (41.8 %), 14 (7.9 %), 38 (21.4 %), 40 (22.6 %), 6 (3.4 %), and 4 (2.2 %) banded patients at 6-12, 24, 36, 48, 60, and 72 months after banding, respectively. Most of intragastric band migration during the first 2 years occurred in bands with no or a few milliliters of filling. In patients with late erosion, the bands were adjusted several times; no band was overfilled but one was filled to the maximum or submaximum with a maximum of two adjustments. Erosions diagnosed during the first 24 months were related to the experience of the surgical staff, while late erosions were not. Conclusions: Intragastric band migration or band erosion is a rare, disturbing, and usually not life-threatening complication of gastric banding. Its pathogenesis is probably linked to different mechanisms in early (technical failure in retrogastric passage) or late (band management) presentation. It is usually asymptomatic and there is no pathognomonic presentation. A wide range of therapeutic options are available, from simple endoscopic or laparoscopic removal to early or late band replacement or other bariatric procedure. More experience and more studies are needed to lower its presentation rate and definitively clarify its pathogenesis to address the right therapeutic option. [ABSTRACT FROM AUTHOR]

This document is a letter to the editor of the ANZ Journal of Surgery discussing the influence of the type of anatomic resection on anastomotic leak after surgery for colon cancer. The authors express their interest in the article and commend the authors for their study. They raise some doubts about the methodology and have several questions regarding the classification of complications, the occurrence of anastomotic leakage, and the influence of medical complications. Despite these limitations, the authors agree with the conclusions and suggest that limited resections for certain types of colon cancer should be included in predictive models for anastomotic leak.

The aim of the study was to evaluate the laparoscopic approach to reoperative bariatric surgery. From January 2003 to July 2007, 26 obesity surgery patients were referred to our Institution for revision. Nineteen patients previously had an open gastric banding, 3 an open vertical banded gastroplasty, 2 an open jejunoileal by-pass (J-l BP) and 2 an open gastric by-pass. Indications for re-operation were insufficient weight loss in 14 patients, band slippage in 7, band erosion in 3 and severe malabsorptive syndrome in 2. Mean preoperative BMI was 45 kg/m2. Twenty-six laparoscopic re-operative procedures were performed. Three patients required a third operation. Eleven gastric banding patients underwent band removal, 7 gastric banding patients were converted to an open gastric by-pass, 1 band was removed and simultaneously re-placed, the 2 jejuno-ileal by-pass patients underwent an intestinal restoration, 3 vertical banded gastroplasty patients were converted to laparoscopic gastric by-pass, 1 open gastric by-pass patient was converted to a laparoscopic long-limb gastric by-pass and in 1 patient with a gastro-gastric fistula after open gastric by-pass the fistula was resected. Further procedures included 1 laparoscopic gastric banding, 1 laparoscopic gastric bypass and 1 laparoscopic bilio-pancreatic diversion. Conversion to laparotomy was needed in 5 cases (5/29, 17.2%). Early complications included 1 case of pneumothorax and 6 cases of wound infection (24.1%). Mortality was zero. The mean follow-up was 36.2 months. Mean postoperative BMI was 34.3 kg/m2. Laparoscopic reoperative bariatric surgery is feasible, safe and effective after open bariatric surgery.

The aim of the study was to evaluate the efficacy of parathyroid hormone 1-hour assay for the early prediction of hypoparathyroidism after thyroidectomy. Candidates for total, subtotal, completion thyroidectomy or lobectomy were entered into the study. Pre- and postoperative calcium and parathyroid hormone (1 hour and postoperative day 1 after thyroidectomy) levels and clinical hypocalcaemia were recorded. Patients were divided into 3 groups and 2 subgroups: 1. patients who underwent lobectomy (control group); 2. patients who underwent total thyroidectomy with postoperative hypocalcaemia (2A: asymptomatic patients, 2B: symptomatic patients); 3. asymptomatic patients with normal calcium levels after total thyroidectomy. Of 119 patients, 109 underwent total thyroidectomy and 10 lobectomy. Of the 109 patients submitted to total thyroidectomy, 35 (32.11%) developed postoperative transient hypocalcaemia. Twenty-one patients (19.27%) were asymptomatic and 14 (12.84%) were symptomatic. Parathyroid hormone levels decreased after 1 hour in group 3 (32.98 pg/dl), 2A (9.84 pg/dl) and 2B (7.46 pg/dl). There was no significant difference in parathyroid hormone levels at 1 hour between group 2A and 2B (p = 0.06), but were significantly lower compared to groups 3 and 1 (p < 0.05). Parathyroid hormone levels at 1 hour after total thyroidectomy is a good predictor of early hypocalcaemia. It might be more useful than serum calcium monitoring for the early identification of patients requiring postoperative calcium supplementation.
