Purpose: To evaluate the feasibility and safety of using the FemoSeal vascular closure device (VCD) to seal 8F access sites during mechanical thrombectomy for stroke., Methods: A retrospective review of a prospective database was undertaken to evaluate the safety and efficacy of femoral arterial closure using FemoSeal device in all patients who underwent mechanical thrombectomy using an 8F sheath between January 2015 and July 2017. Efficacy endpoints were the successful deployment of the system and haemostasis success. Safety endpoints included the incidence of in hospital access site haematoma >5 cm, bleeding complications, pseudoaneurysms, arteriovenous fistula, infection, or other complications requiring surgery., Results: 197 patients (96 men; mean age 68 years, range 25-99) were included. Successful haemostasis with FemoSeal was obtained in 98.9% of the patients. Only one haematoma >5 cm (0.5%) was observed, which reabsorbed spontaneously without issue. Nine haematomas <5 cm (4.5%) were also found. No major complications requiring surgical repair or transfusion were observed. There were no pseudoaneurysms, arteriovenous fistulae, or infections., Conclusion: The use of the FemoSeal device to close an 8F access sheath puncture site is feasible and safe, with a low complication rate., (Copyright © 2018 European Society for Vascular Surgery.

Background: Gastric leak (GL) is one of the main early-onset postoperative complications of sleeve gastrectomy (SG). Many institutions perform routine upper gastrointestinal (UGI) contrast studies within 24 hours of surgery, looking for GL or gastric stenosis and to determine the need for urgent re-exploration, but this examination delays oral feeding, can cause side effects and is responsible for systematic and probably unnecessary irradiation of the patient., Objective: Determine the efficacy of routine UGI contrast studies to predict postoperative complications after SG in a large population., Setting: University hospital, France, public practice., Material and Methods: This study consisted of retrospective review of a prospective database of a cohort of patients who underwent primary SG between January 2007 and August 2013 (n = 1137). Routine UGI contrast studies, performed on postoperative day 1, were independently reviewed by 2 radiologists. The primary endpoint of the study was the effect of routine UGI contrast study on detecting postoperative complications. The secondary endpoints were comparison of the findings of routine UGI contrast study and abdominal computed tomography (CT) scan, sensitivity, and specificity of different imaging signs on abdominal CT scan in the presence of GL, evaluation of the SG learning curve based on the findings of routine UGI contrast studies., Results: A total of 1137 patients underwent primary SG and 30 GL (2.6%) with a mean time to diagnosis of 23.4 days (1-245) and 15 cases of gastric stenosis (1.3%) were observed during the study period. Routine UGI study was performed in 1108 patients, whereas 29 patients were assessed by first-line CT scan. None of the 1108 UGI studies found a GL or gastric stenosis. In the 30 cases of GL, the most sensitive and specific sign was the presence of perigastric abscess without contrast material leak (sensitivity: 56.6%; specificity: 95%). The mean time interval between routine postoperative UGI contrast study and abdominal CT scan was 12.9 days (0-86). Uniform gastric shape was acquired after 30-32 SG procedures., Conclusion: Routine postoperative UGI on postoperative day 1 is of limited value after SG. Abdominal CT scan should be preferred in the presence of clinical suspicion of postoperative complications. Selective UGI contrast study remains indicated when gastric stenosis is suspected and at the beginning of the SG learning curve., (Copyright © 2017 American Society for Bariatric Surgery.

Background: Recent series have shown the lack of value of routine upper gastrointestinal (UGI) contrast studies on postoperative day 1 or 2 for the detection of gastric leak (GL) after sleeve gastrectomy (SG). Despite this finding, many centers still perform routine early UGI contrast studies after SG. No series has evaluated the impact of eliminating this examination on the overall management of patients undergoing SG., Objectives: To evaluate the impact of UGI contrast studies on SG management., Setting: University hospital, France, public practice., Methods: This study was an ambispective study of a cohort of patients who underwent primary SG between January 2014 and December 2014 (n = 267). Two consecutive groups were compared: patients with routine UGI contrast studies on postoperative day 1 (UGI+group, n = 154) and patients without routine UGI contrast studies (UGI-group, n = 113). The efficacy endpoint of the study was the overall impact of not performing routine UGI contrast studies (length of hospital stay, radiological data, rehospitalization data, and economic assessment)., Results: The overall complication rate was 9.3% and no deaths were observed. The GL rate was 1.5%. The mean hospital stay was 1.8 days (2.1 days versus 1.5 days; P = .57). Routine UGI contrast studies did not detect any cases of GL or gastric stenosis. After UGI contrast studies, 56 patients complained of events related to UGI contrast studies (36.4%). A total of 27 computed tomography scans were performed during the first 3 postoperative months (16 in the UGI+group (10.4%) versus 11 in the UGI-group (9.7%); P = .52). Twelve patients were rehospitalized (7 and 5; P = .6). The median length of rehospitalization was 7 days (7 and 5 days; P = .6). Overall cost per patient during SG hospitalization was $5,219 in the UGI+group and $3,678 in the UGI-group (P = .01)., Conclusion: Eliminating routine UGI contrast studies was associated with decreased length of hospital stay and cost of SG procedures. Larger series are required to show that not performing routine UGI contrast studies has no impact on the postoperative complication rate and the management of these complications., (Copyright © 2017 American Society for Bariatric Surgery.

Background: Gastric leak (GL) represents one of the main early-onset postoperative complication of sleeve gastrectomy (SG). Most studies of GL featured short series and no data on the time to reoperation for persistent GL., Objectives: Characterize the time between discovery of persistent post-SG GL and the implementation of reoperation., Setting: University hospital, France, public practice., Methods: All patients treated for post-SG GL between November 2004 and December 2013 were included. The primary efficacy criterion was the time interval between discovery of a persistent GL and reoperation. The secondary efficacy criteria were demographic, surgical, and endoscopic data; mortality rate; time to GL healing; treatment success rate; and risk factors for failure treatment., Results: Eighty-six patients were treated for post-SG GL. Forty patients (46.5%) had early-onset GL (postoperative day ≤ 7). Two patients (2.3%) presented primary gastrobronchial fistula. Fifty-six patients (70%) underwent immediate reoperation. Endoscopic treatment was required to treat the GL in 92.7% of the cases (n = 77). The mortality rate was 1.2% (n = 1). The treatment success rate was 89.1%. The median time to healing GL was 84 days (14-423 d). Eighty percent of the GLs had healed 120 days after discovery. After 120 days, the incidence of complications related to GL increased and few additional GLs healed. The only identified risk factor for treatment failure was large retained gastric fundus (P ≤ .05)., Conclusions: Most cases of GL can be adequately treated by incorporating endoscopic stenting. Surgery for persistent GL should be performed within 120 days of discovery; after this cut-off, the incidence of GL-related complications increases. Large retained gastric fundus is a risk factor for treatment failure and may prompt the surgeon to consider earlier reoperation., (Copyright © 2016 American Society for Bariatric Surgery.

Mirizzi syndrome, a rare complication of gallstones, is defined by obstruction of the main bile duct. This obstruction may worsen and thus result in cholecystobiliary fistula. Surgical management of Mirizzi syndrome is complicated by the presence of inflamed tissue around the hepatic pedicle, making it impossible to distinguish between the main bile duct and the gallbladder. The surgeon's first task is to perform subtotal cholecystotomy (from the fundus of the gallbladder to the neck) without trying to locate the cystic duct. In a second step, the gallstones are extracted and the main bile duct is then repaired. In most cases, a T-tube is used to drain the main bile duct, and abdominal drainage is left in place (in case a bile fistula forms). This study concluded that preoperative drainage of the main bile duct in the treatment of Mirizzi syndrome types II and III is feasible and might help to decrease the postoperative complication rate.

Background: Obesity is recognized as a risk factor for trocar site hernia (TSH) after laparoscopic surgery. Some recent studies have reported a TSH rate after bariatric surgery ranging from 0% to 1.6% using clinical evaluation and may underestimate the TSH rate. The objective of this study was to evaluate the TSH rate after sleeve gastrectomy (SG) by abdominal computed tomography (CT) scan., Methods: A retrospective review of all patients who underwent first-line SG and abdominal CT scan between March 2004 and February 2014 was performed. The primary endpoint was the incidence of TSH. Secondary endpoints were the site of TSH, the TSH rate with open laparoscopy using the authors' technique, and risk factors for TSH after SG., Results: During the period study, 1108 patients underwent first-line SG, including 10 cases of conversion to laparotomy (excluded from the present analysis). Of the remaining patients, 228 had abdominal CT scan (20.7%), with a mean age of 45.1 years (18-68 yr) and a mean BMI of 47.6 kg/m(2) (33-75.4 kg/m(2)). The median time interval between SG and CT scan was 27 months (3-92 mo). CT scan revealed 44 TSH in 43 patients (18.8%). The site of the TSH was epigastric (16.6%), open laparoscopy (1.7%), right subcostal margin (0.8%), with no TSH in the left subcostal margin. In patients with>1 year of follow-up, the TSH rate was 19.7%., Conclusion: The TSH rate after bariatric surgery is underestimated. The authors' open laparoscopy technique is a reliable technique with a low TSH rate. In the light of these results, the epigastric trocar site is systematically closed at the end of SG., (Copyright © 2015 American Society for Bariatric Surgery. Published by Elsevier Inc.

Background: Gastric fistula (GF) is a serious complication after laparoscopic sleeve gastrectomy (LSG). Furthermore, gastrobronchial fistula (GBF) may appear some time after a primary LSG. The objective of this study was to characterize GBF after LSG and establish standardized treatment procedures., Methods: All patients undergoing surgery for GBF after LSG at a public university medical center in France between November 2004 and January 2013 were included in this study. Surgical and perioperative care was standardized. The primary efficacy criterion was the complication rate. Secondary efficacy criteria were the mortality rate, surgical data, types of complications, and the length of stay (LOS) in hospital., Results: Six patients were treated for GBF after LSG: 2 presented GBF after primary LSG performed in our institution and 4 had been referred by tertiary centers. The median (range) time to onset of GBF after LSG was 136 days (99-238 d). Preoperative refeeding was performed in 5 cases. The median time interval between the discovery of GBF and its surgical treatment was 31 days (7-137 d). Five patients underwent simultaneous abdominal and thoracic procedures. The abdominal procedures consisted of total gastrectomy (n = 1) and 60-cm Roux-en-Y gastrojejunal anastomosis (n = 6). There were no postoperative mortalities. Four postoperative complications occurred (66.6%), 2 of which were postoperative fistulas (33.3%) requiring revisional surgery. The median time to oral refeeding was 10 days (8-65 d) and the median LOS was 14 days (13-25 d)., Conclusions: Our treatment of GBF is based on effective drainage with endoscopic procedures, allowing optimal preoperative refeeding before combined abdominal and thoracic surgery. For the abdominal procedure, we prefer a 60-cm Roux-en-Y gastrojejunal anastomosis to total gastrectomy, because the former is simpler and minimizes the long-term risk of postoperative malabsorption., (© 2013 American Society for Bariatric Surgery Published by American Society for Metabolic and Bariatric Surgery All rights reserved.)

Background: The Frey procedure (FP) is the treatment of choice for symptomatic chronic pancreatitis (CP). In cases of biliary stricture, biliary derivation can be performed by choledochoduodenostomy, Roux-en-Y choledochojejunostomy or, more recently, reinsertion of the common bile duct (CBD) into the resection cavity. The objective of the present study was to evaluate the outcomes associated with each of these three types of biliary derivation., Methods: We retrospectively analyzed demographic, CP-related, surgical and follow-up data for patients having undergone FP for CP with biliary derivation between 2004 and 2012 in our university medical center. The primary efficacy endpoint was the rate of CBD stricture recurrence. The secondary endpoints were surgical parameters, postoperative complications, postoperative follow-up and the presence of risk factors for secondary CBD stricture., Results: Eighty patients underwent surgery for CP during the study period. Of these, 15 patients received biliary derivation with the FP. Eight of the FPs (53.3%) were combined with choledochoduodenostomy, 4 (26.7%) with choledochojejunostomy and 3 (20.0%) with reinsertion of the CBD into the resection cavity. The mean operating time was 390 minutes. Eleven complications (73.3%) were recorded, including one major complication (6.7%) that necessitated radiologically-guided drainage of an abdominal collection. The mean (range) length of stay was 17 days (8-28) and the median (range) follow-up time was 35.2 months (7.2-95.4). Two patients presented stricture after CBD reinsertion into the resection cavity; one was treated with radiologically-guided dilatation and the other underwent revisional Roux-en-Y choledochojejunostomy. Three patients presented alkaline reflux gastritis (37.5%), one (12.5%) cholangitis and one CBD stricture after FP with choledochoduodenostomy. No risk factors for secondary CBD stricture were identified., Conclusions: As part of a biliary derivation, the FP gave good results. We did not observe any complications specifically related to surgical treatment of the biliary tract. However, CBD reinsertion into the resection cavity appeared to be associated with a higher stricture recurrence rate. In our experience, choledochojejunostomy remains the "gold standard" for the surgical treatment for CBD strictures.

Background: Causes of failure after laparoscopic sleeve gastrectomy (LSG) are not known but may include a high residual gastric volume (RGV). The aim of this study was to use gastric computed tomography volumetry (GCTV) to investigate the RGV and relate the latter parameter to the outcome of LSG., Methods: A single-center, prospective study included patients with>24 months of follow-up after LSG. The RGV was measured with a unique GCTV technique. We determined the LSG outcomes according to a variety of criteria and examined potential relationships with the RGV. When the RGV was>250 cc, we offered a repeat LSG (RLSG)., Results: Seventy-six patients were included. The mean RGV was 255 cc but differed significantly when comparing "failure" and "success" subgroups, regardless of whether the latter were defined by a percentage of excess weight loss>50 (309 cc versus 225 cc, respectively; P = .0003), a BAROS score>3 (312 cc versus 234 cc; P = .005), the Reinhold criteria (290 cc versus 235 cc; P = .019), or the Biron criteria (308 cc versus 237 cc; P = .008). The RGV threshold (corresponding to the volume above which the probability of failure after LSG is high) was 225 cc. Fifteen RLSGs were performed during the inclusion period., Conclusion: A high RGV 34 months after LSG is a risk factor for failure. Knowledge of the RGV can be of value in the management of failure after LSG., (Copyright © 2013 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.)

Objective: The Glissonian approach during hepatectomy is a selective vascular clamping procedure associated with low rates of technical failure and complications. The aim of the present study was to assess the feasibility of a right Glissonian approach in relation to portal vein anatomy., Methods: This was a prospective study conducted over a 12-month period, which included 32 patients for whom preoperative three-dimensional reconstruction using contrast-enhanced computed tomography in the portal venous phase and portography for right portal vein embolization were available, and in whom a right Glissonian approach was applied during right hepatectomy. Preoperative imaging data were correlated with intraoperative Doppler ultrasound findings (considered as the reference dataset). Causes of failures and complications specifically related to the Glissonian approach were identified., Results: Right hepatectomy was performed for colorectal liver metastases (n = 25), hepatocellular carcinoma on cirrhosis (n = 6) and intrahepatic cholangiocarcinoma (n = 1). The Glissonian approach was effective in 24 (75%) patients. In the remaining eight (25%) patients, failure was caused by incomplete clamping (n = 2) or clamping of the left portal pedicle (n = 6). The portal anatomy was aberrant in six patients with failure, showing portal trifurcation (n = 1), right portal trifurcation (n = 1) and a common trunk between the right anterior and left portal branch (n = 4). An angle of less than 50° between the portal vein and left portal branch was reported in association with extended clamping to the left portal branch (selectivity = 72%, specificity = 71%). Intraoperative bleeding and biliary fistula occurred in two patients with non-normal portal anatomy., Conclusions: The right Glissonian approach was effective in 75% of patients. Failure of the procedure (including the extension of clamping to the left pedicle) mostly occurred in patients with portal vein variations, which can be accurately assessed using a combination of preoperative imaging and intraoperative Doppler ultrasound., (© 2013 International Hepato-Pancreato-Biliary Association.)

Background: During a pancreatectomy, the left gastric vein (LGV) has an important role in the venous drainage of the stomach (total pancreatectomy, left splenopancreatectomy, pancreatoduodenectomy with venous resection and pylorus-preserving pancreaticoduodenectomy). Pre-operative knowledge of the LGV's termination is necessary for adequate protection of this vein during dissection. The objective of the present study was to analyse the location of the LGV's termination in a patient population and facilitate its identification in at-risk situations., Materials and Methods: Abdominal computed tomography (CT) images of 86 pancreatic tumour patients (20 of whom underwent surgery), who were treated in our institution between October 2009 and October 2010, were reviewed. Arterial-phase and portal-phase helical CT with three-dimensional reconstruction was performed in all cases. The location of the termination of the LGV was determined and (when the LGV merged with the splenic vein or the splenomesenteric trunk) the distance between the termination and the origin of the portal vein (PV). The correlation between CT imaging data and intra-operative findings was studied., Results: The LGV was identified on all CT images. In 65% of cases (n= 56), the LGV terminated in the PV (upstream of the liver in nine of these cases). The LGV terminated at the splenomesenteric trunk in 4.7% of cases (n= 4) and in the splenic vein in 30.3% of cases (n= 26). When the LGV terminated upstream of the origin of the PV, the distance between the two was always greater than 1 cm. The average distance between the termination of the LGV and the origin of the PV was 14.34 mm (10.2 to 21.1). The anatomical data from CT images agreed with the intra-operative findings in all cases., Conclusion: Pre-operative analysis of the LGV is useful because the vein can be identified in all cases. Knowledge of the termination's anatomic location enables the subsequent resection to be initiated in a low-risk area., (© 2012 International Hepato-Pancreato-Biliary Association.)
