Case Report: Endoscopic Removal of an Eroded Gastric Band Causing Small Bowel Obstruction upon Migration into the Proximal Jejunum.

Obes Surg 2020 Dec 11;30(12):5153-5156. Epub 2020 Aug 11.

Department of Minimally Invasive and Bariatric Surgery, Hôpital du Sacré-Coeur, CIUSSS du Nord de l'île de Montréal, 5400 Boulevard Gouin Ouest H4J 1C5, Québec, Montréal, Canada.

Background: Adjustable gastric banding (AGB) is on the decline due to its relatively modest amount of expected weight loss, coupled with high rates of revision and complications such as band erosion. Management of eroded gastric bands can be challenging especially when complete intra-gastric erosion is followed by distal migration causing small bowel obstruction.

Methods: We present an endoscopic option of using a pediatric colonoscope to remove an eroded AGB causing jejunal obstruction.

Result: Endoscopic removal of an eroded ABG causing bowel obstruction was successful.

Conclusion: Endoscopy remains a safe and relatively non-invasive approach to deal with such complications.

Efficiency of Laparoscopic One-Step Revision of Failed Adjusted Gastric Banding to Gastric Sleeve: a Retrospective Review of 101 Consecutive Patients.

Obes Surg 2019 12;29(12):3868-3873

Division of Bariatric Surgery, Department of Surgery, Hôpital du Sacré-Coeur de Montréal, University of Montreal, Montreal, QC, H4J1C5, Canada.

Background: Until recently, laparoscopic adjustable gastric banding (LAGB) was one of the most commonly performed bariatric surgeries worldwide. Today, its high rate of complications and failure rates up to 70% requires revisional surgery. The one-stage conversion from LAGB to laparoscopic sleeve gastrectomy (LSG) has been shown to be safe, although there are some concerns on efficacy and long-term weight loss.

Objectives: To demonstrate that one-step revision of LAGB to another restrictive procedure, such as LSG, might have efficient long-term outcomes.

Methods: The charts from 133 revisional LSGs for failed or complicated LAGB were retrospectively reviewed for the period between January 2010 and August 2017. Thirty-two patients were excluded for loss to follow-up. Demographics, complications, and percentage of excess weight loss (%EWL) were determined.

Results: One hundred one patients were included (85 women and 16 men), with a mean age of 48.5 years, and a mean body mass index of 47.1 kg/m. During the follow-up, 15 patients (15%) underwent a second revisional surgery for weight loss failure (8 Roux-en-Y gastric bypass (RYGBP), 3 biliopancreatic diversion, 3 single anastomosis duodenal-ileal bypass, 1 revisional LSG). Ten patients (10%) had long-term complications (8 severe reflux and 2 stenosis) during this period and underwent a second revisional surgery (10 RYGBP). The remaining 76 had a mean follow-up of 4.3 years and a mean %EWL of 53.2%.

Conclusion: Single-stage conversion to LSG is a safe and appropriate solution for failed or complicated LAGB with good long-term weight loss.

Characteristics and natural history of patients with colorectal cancer complicated by infectious endocarditis. Case control study of 25 patients.

Anticancer Res 2014 Jan;34(1):349-53

Service de Chirurgie Digestive et viscérale, Pôle DACCORD, Hopital Timone .264 rue saint Pierre, 13385 Marseille, France.

Unlabelled: Association between streptococcal endocarditis and gastrointestinal disease has been well-documented in the literature. However oncological impact of this complicated presentation has not yet been reported. We have conducted to our knowledgethe first case-control study on this subject.

Patients And Methods: Two groups of five patients with colorectal cancer and either active endocarditis (CRC E+), or without endocarditis (CRC, n=20) were matched 1:4 for age, sex, and location of colorectal tumor.

Results: All 25 patients were male, with a median age of 63 (range: 53-85) years. Twenty (80%) had colon cancer and 5 (20%) rectal cancer. There was no post-operative mortality in this population. The overall morbidity was 28% (n=7). The overall 3-year survival and recurrence rates were similar in both groups 80% and 95%; 0% and 30% for group CRC E+ and CRC (p=0.4603).

Conclusion: This is the first case-control study demonstrating that during the first two years of follow-up, occurrence of endocarditis did not alter the prognosis of patients with CRC.
