Long-term results of laparoscopic gastric sleeve: the importance of follow-up adherence.

OBJECTIVE: This study was conducted to assess the long-term results of the Laparoscopic Sleeve Gastrectomy (LSG) in patients not compliant with follow-up, and in patients who completed a postoperative follow-up program. PATIENTS AND METHODS: The data concerning LSG patients operated from February 2011 to December 2013 were retrospectively reviewed basing on a single center database. The patients with complete long-term follow-up were scheduled in Group A, while patients who failed to attend controls for more than two years were scheduled in Group B. Long-term results (weight loss, comorbidity improvement and late complications) were compared between the two groups. RESULTS: The study population consisted of 285 patients. Of these, 101 had a complete follow-up with a mean duration of 71 ± 7.6 months (Group A). The remaining 184 patients (Group B) were not compliant with follow-up and, consequently, the mean duration of follow-up was 5.5 ± 7.3 months (p < 0.00001). A higher number of patients with insufficient weight loss was recorded in Group B with respect to Group A (78 vs. 23; p = 0.001). The number of patients with results below 25% EWL was significantly higher in Group B than in Group A (24 vs. 5; p = 0.04). In the long-term, the rate of patients with symptomatic reflux requiring medical treatment was two-fold higher in Group B than in Group A. CONCLUSIONS: The adherence to a long-term follow-up plan after LSG seems to decrease the number of patients experiencing insufficient weight loss and those at risk for developing a gastro-esophageal reflux disease.

Gastric Bypass after multiple restrictive procedures: Roux-en-Y or One Anastomosis? A retrospective multicentric study.

OBJECTIVE: When restrictive surgery fails, conversion to more malabsorptive techniques is frequently proposed. The aim of this study is to evaluate the weight loss figures between Roux-en-Y Gastric Bypass (RYGB) and One Anastomosis Gastric Bypass (OAGB) in patients who have already undergone Multiple Restrictive Procedures (MRP). PATIENTS AND METHODS: All patients who underwent conversion of Laparoscopic Sleeve Gastrectomy (LSG) to RYGB or OAGB between 2010 and 2019 were retrospectively analyzed. Only patients who had conversion for Weight Regain (WR) or Insufficient Weight Loss (IWL) after both Laparoscopic Gastric Banding (LGB) and LSG entered the study population. Finally, 44 patients underwent conversion to RYGB, and 24 patients to OAGB. RESULTS: Concerning Excess Weight Loss (%EWL) at 3, 6, 12, 24 postoperative months, the results for RYGB were 33.7%, 47.95%, 61.8%, 61.8%, while for OAGB were 38.3%, 51.9%, 63.75%, 79.45%. A significant difference was recorded in favor of OAGB at 3 (p=0.03) and 24 (p=0.046) postoperative months. % EWL at 24 months in the case of IWL was 57.8% for RYGB, while for OAGB was 72.7% (p=0.047). No significant difference was found considering patients with WR (80.9% and 80.5%; p= 0.999). Patients with better results at 24 months after surgery had a significantly longer time between sleeve and bypass than those with a lower % EWL. CONCLUSIONS: The results of the present study seem to show that both techniques give good results at 24 months in patients who have undergone MRP. However, OAGB shows overall better results, particularly in patients with IWL.

Laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography: Preliminary experience and technique description.

INTRODUCTION: Common bile duct lithiasis after Roux-en-Y gastric bypass (RYGB) or upper gastrointestinal stenosis has become a challenging problem nowadays, especially as obesity surgery is increasing. In this study, we assess the feasibility and performance of laparoscopy-assisted transgastric endoscopic retrograde cholangiopancreatography (LAERCP) and describe its technique. METHODS: A retrospective review of a prospectively collected database of consecutive patients undergoing a LAERCP between February 2014 and May 2015 was performed at a single institution. Indications were common bile duct lithiasis associated with acute or past episodes of cholangitis and pancreatitis. Endoscopic access to the gastric remnant was obtained laparoscopically. RESULTS: In total 5 cases were identified. Four of them had undergone a RYGB and one of them presented a benign esophageal peptic stenosis, not allowing peroral gastric access. Biliary cannulation using LAERCP associated with sphincterotomy and stone extraction was successfully achieved in all patients. Mean duration of the entire procedure was 134minutes (range: 66-200min). No early major complications were observed and the mean postoperative hospital stay was 4 days (range: 2-5 days). CONCLUSIONS: LAERCP is a safe and successful procedure for the treatment of common bile duct lithiasis when conventional biliary access is not feasible, notably after RYGB. Larger trials still need to be performed to evaluate efficacy, technical success, and complications related to this technique.

Risk of Dumping Syndrome after Sleeve Gastrectomy and Roux-en-Y Gastric Bypass: Early Results of a Multicentre Prospective Study.

Background. Bariatric surgery is an important field of surgery. An important complication of bariatric surgery is dumping syndrome (DS). Aims. To evaluate the incidence of DS in patients undergoing bariatric surgery. Methods. 541 patients included from 5 nutrition and bariatric centers in France underwent either LSG or LRYGB. They were evaluated at 1 month (M1) and 6 months (M6) postoperatively by an interview and completion of a dumping syndrome questionnaire. Results. 268 patients underwent LSG (Group A) and 273 underwent LRYGB. From the LRYGB patients 229 had mechanical gastrojejunoanal anastomosis with 30 mm linear stapler (Group B) and 44 had manual (hand sewn) 15 mm gastrojejunal anastomosis (Group C). Overall incidence of DS was 8.5% at M1 and M6. In LSG group (Group A), only 4 patients (1.49%) reported episodes of DS at M1 and 3 (1.12%) at M6. In Group B, 41 patients (17.90%) reported episodes of DS at M1 and 43 (18.78%) at M6. Group C experienced one case (2.27%) of DS at M1 and none (0%) at M6. Conclusions. Patients undergoing LRYGB, especially with larger gastrojejunal anastomosis, are more prone to developing DS following surgery than patients undergoing LSG or LRYGB with calibrated manual anastomosis.

SPIDER ® sleeve gastrectomy--a new concept in single-trocar bariatric surgery: initial experience and technical details.

INTRODUCTION: Single port instrument delivery extended reach (SPIDER(®)) surgical system is a revolutionary surgical platform that allows triangulation of the surgical instruments while eliminating the crossing of instruments, the problematic characteristic of single access laparoscopic surgery. METHODS: The purpose of this study was to analyze our initial experience with SPIDER(®) sleeve gastrectomy and to present the technical details of this new minimally invasive approach, performed in ten patients at the La Casamance Private Hospital between November 2012 and April 2013. All patients were reviewed at scheduled post-operative consultations at 1, 3 and 6 months. In addition to clinical examination, the post-operative consultation at one month also included a satisfaction survey using the Moorehead-Ardelt questionnaire. RESULTS: An initial series of ten sleeve gastrectomies were performed in female patients with a mean age of 41.5 years (range: 2-52). The mean BMI was 40.11 (range: 37.25-44.3). The intervention was performed through a single trocar in all patients with no "conversion" to classic laparoscopy or open surgery. The mean operative time was 61 ± 15.22 minutes (SD=standard deviation) (range: 43-96 min). The mean BMI at one month was 35.5 (SD:± 3.58, SEM: ± 1.13) (SEM=standard error of mean) with an average percentage of excess weight loss (%EWL) of 32.9% (SD:± 8.56%, SEM:± 2.71%). The mean BMI at three months was 32.4 (SD: ± 2.78, SEM: ± 0.88) with an average %EWL of 52.7% (SD: ± 8.64%, SEM: ± 2.73%). The mean BMI at six months was 29.9 (SD:± 2.60, SEM: ± 0.98) with a mean %EWL of 68.8% (SD: ± 8.38%, SEM:± 3.17%). Complete remission of co-morbid conditions was observed in four patients, improvement in three others, and no change in a single patient. The mean duration of hospitalization was 3.1 days. The mean follow-up period was 161 days (SD:± 57.4 days, range: 90-243 days). There was no mortality and no intra-operative and post-operative complications were noted. CONCLUSIONS: The SPIDER(®) surgical platform seems to be a usable and effective method for performance of minimally invasive single-access sleeve gastrectomy, offering an easy and efficient operative procedure compared to other single-port systems. Prospective long-term studies are recommended before this approach can be validated to be of comparable efficiency to conventional multi-port laparoscopic surgery.

Single incision laparoscopic cholecystectomy.

BACKGROUND: As surgeons embrace the concept of increasingly less invasive surgery, techniques using only a single small incision have begun to gain traction. Multiple case series managed by a single-incision laparoscopic cholecystectomy (SILC) have been published. The objective of this study is to describe the short-term outcomes of SILC in our institution. METHODS: A retrospective review was done for 51 patients who underwent SILC between 2009-2012. The operative time, surgical technique, conversion rate, and postoperative complications were reported. RESULTS: SILC was performed for 51 patients, all women, with a mean age of 35.6 years (range=19-62). Their body mass index(BMI) ranged from 16.8-35.6 kg m2 with a mean of 20.4. Twelve patients (23.52 %) had acute cholecystitis. The mean operating time was 58.6 minutes (range=45-95 min). Incidents were encountered in 6 patients (11.76%) and were related to intraoperative bleeding. There was a single conversion to the standard laparoscopic procedure (1.9%) and in 5 cases an accessory needle grasp was used (9.8%). Two patients (3.9%)presented postoperative complications (wound infections) and the mean hospital stay was 1.6 days. CONCLUSIONS: SILC is feasible and provides a promising alternative to natural orifice transluminal endoscopic surgery for scarless laparoscopic cholecystectomy. However, routine application of this novel technique requires an evaluation of its safety and cost effectiveness in larger studies.

New CT scan classification of leak after sleeve gastrectomy.

Laparoscopic sleeve gastrectomy (LSG) has become one of the most common bariatric procedures. Even so, the gastric leak remains the most feared complication with a difficult, non-standardized treatment. The purpose of this study was to assess the feasibility of a new classification of leakage after LSG used in Montpellier University Hospital. We have studied the correlations between radiological findings and therapeutic outcome for the 20 gastric leaks. The presence of a leak was evaluated according to the day of appearance, the symptomatology, the location, severity on the CT scan, and the management. From May 2010 to September 2012, we prospectively collected data from 20 patients diagnosed with gastric leak after LSG. There were 16 women and 4 men with a mean age of 34 years old (range 21-52 years old). The fistula was diagnosed at postoperative day 28.1 days (range 3-77 days). Patients were grouped by the new classification in: 11-type I, 6-type II, 3-type III fistula, and 0-type IV. The visualization of leakage was observed for five cases (25 %). The initial surgical drainage was performed for 11 cases and the conservative treatment was preferred in 9 cases. Three cases necessitated a delayed surgical drainage after 1 week of conservative treatment. The surgical drainage was performed by laparoscopy in 12 cases and by laparotomy in 2 cases. The new CT scan classification of gastric leak could serve as a working basis for a consensus on the therapeutic management of this dreaded complication.

A review of available prosthetic material for abdominal wall repair.

Abdominal wall incisional and inguinal hernia repair can call for utilization of implants or prostheses as an alternative to simple suture techniques. The various implants can be synthetic, biologic or mixed: their physicochemical properties condition the mechanical results and the long-term outcome of the repair. The increasing number of available materials allows the surgeon to choose between a wide variety depending on the indication, the site of implantation, the surgical approach and whether the operative field is contaminated or not. With regard to evidence-based medicine, while several synthetic implants have been shown to be superior in efficacy to simple suture, other studies are underway to develop the indications for bioprostheses, in particular in contaminated fields. This review of the literature summarizes the current knowledge on synthetic and biologic implants (physicochemical characteristics, forms, indications).
