Endoscopic treatment of large gastric leaks after gastrectomy using the combination of double pigtail drains crossing a covered stent.

BACKGROUND: Endoscopy is the gold standard for the treatment of postoperative gastric leaks (GL). Large fistulas are associated with high rate of treatment failure. The objective of this study was to assess the clinical efficacy of a combining technique using a covered stent (CS) crossing through pigtails (PDs) for large postsurgical GL leaks. METHODS: All consecutive patients with large (> 10 mm) postsurgical GL treated endoscopically with a combination of a CS and PDs were included in a single-center retrospective study. The primary endpoint was the rate of GL closure. RESULTS: A total of 29 patients were included. Twenty-five patients underwent sleeve gastrectomy. The fistula (median diameter 15 mm) was diagnosed 6 days (IQR 4-9) after surgery. Technical success was observed in all procedures. After a median follow-up of 10.7 months (IQR 3.8-20.7), GL closure was observed in 82.7% with a median time of 63 days (IQR 40-90). Surgical management was finally necessary in four patients after a median of 186 days (IQR 122-250). No complications related to combined endoscopic treatment were observed especially stent migration during the follow-up. CONCLUSION: An endoscopic strategy combining CS crossing through PDs appears to be effective, safe and well tolerated for the treatment of large GL.

Safety and efficacy of percutaneous transhepatic-endoscopic rendezvous procedure in a single session.

PURPOSE: To demonstrate the feasibility and safety of PTE-RV performed in a single session. MATERIALS AND METHODS: This is a retrospective review of a prospective database on ERCP between January 2014 and December 2018. PTE-RV was performed in case of second ERCP failure. Technical success was defined as the establishment of an intestinal access to the biliary tract using a PTE-RV procedure allowing an immediate internal biliary drainage. Safety endpoints included intra-operative complications, morbidity and mortality occurring within 30 days after the procedure. RESULTS: Eighty-four patients (44 M/40F) with a median age of 69 years (range 40-91 years) underwent combined PTE-RV. The PTE-RVs were successfully performed in the same session in 80 subjects, resulting in an overall technical success rate of 95.2%. Adverse events were observed in 19% (16/84) of cases. The mortality rate within 30 days after the procedure was 9.5%. CONCLUSION: Percutaneous transhepatic-endoscopic rendezvous technique is feasible in a single session with acceptable level of risk. A randomized trial is required to compare EUBD and PTE-RV.

How can recovery be enhanced after single-stage laparoscopic management of CBD stones? Endoscopic treatment versus laparoscopic surgery.

BACKGROUND: Single-stage management of CBD stones comprises simultaneous common bile duct (CBD) clearance and cholecystectomy. The CBD can be cleared by using endoscopic treatment (ET) or laparoscopic surgery (LS) alone. AIMS: To determine the most rapid recovery after the single-stage laparoscopic management of CBD stones. METHODS: Patients with CBD stones treated at either of two centers (one performing ET only and one performing LS only for single-stage treatment) were included. The primary endpoint was "the textbook outcome". RESULTS: The feasibility rate was 74% for ET and 100% for LS (p≤0.001). The proportion of cases with the textbook outcome was higher in the ET group than in the LS-only group (73% vs. 10%; p<0.001). The CBD clearance rate was similar in the ET and LS-only groups (100% vs. 96.6%, respectively; p=0.17). The overall morbidity rate was lower in the ET group than in the LS-only group (23% vs. 29%, p=0.05). CONCLUSION AND RELEVANCE: Both ET and LS are feasible, safe and effective for clearance of the CBD. ET was better than LS in terms of a less frequent requirement for drainage and a shorter length of hospital stay. LS was associated with a shorter operating time.

Combined radiologic and endoscopic treatment (using the "rendezvous technique") of a biliary fistula following left hepatectomy.

Despite the ongoing decrease in the frequency of complications after hepatectomy, biliary fistulas still occur and are associated with high morbidity and mortality rates. Here, we report on an unusual technique for managing biliary fistula following left hepatectomy in a patient in whom the right posterior segmental duct joined the left hepatic duct. The biliary fistula was treated with a combined radiologic and endoscopic procedure based on the "rendezvous technique". The clinical outcome was good, and reoperation was not required.

Persistent gastric fistula after sleeve gastrectomy: an analysis of the time between discovery and reoperation.

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.

Laparoscopy-assisted open cystogastrostomy and pancreatic debridement for necrotizing pancreatitis (with video).

INTRODUCTION: Pancreatic pseudocysts and walled-off necrosis are well-known complications, described in 10% of cases of acute pancreatitis. Open cystogastrostomy is usually proposed after failure of minimally invasive drainage or in the presence of septic shock. The objective of this study was to evaluate the feasibility and efficacy of laparoscopy-assisted open cystogastrostomy for treatment of symptomatic pancreatic pseudocyst with pancreatic necrosis. MATERIALS AND METHODS: Between January 2011 and October 2014, all patients with pseudocyst and pancreatic necrosis undergoing open cystogastrostomy were included. Surgical procedure was standardized. The primary efficacy endpoint was the feasibility and efficacy of laparoscopy-assisted open cystogastrostomy as treatment of symptomatic pancreatic pseudocyst. Secondary endpoints included demographic data, preoperative management, operative data, postoperative data and follow-up. RESULTS: Laparoscopy-assisted open cystogastrostomy was performed in 11 patients [six men (54%)], with a median age of 61 years (45-84). Nine patients received preoperative radiological or endoscopic management. First-line open cystogastrostomy was performed in two cases. Median operating time was 190 min (110-240). There was one intraoperative complication related to injury of a branch of the superior mesenteric vein. There were no postoperative deaths and two postoperative complications (18%) including one major complication (postoperative bleeding). The median length of hospital stay after surgery was 16 days (7-35). The median follow-up was 10 months (2-45). One patient experienced recurrence during follow-up. CONCLUSION: Open cystogastrostomy for necrotizing pancreatitis promotes adequate internal drainage with few postoperative complications and a short length of hospital stay. However, this technique must be performed very cautiously due to the risk of vascular injury which can be difficult to repair in the context of severe local inflammation related to pancreatic necrosis.

Gastric leaks after sleeve gastrectomy: no impact on weight loss, co-morbidities, and satisfaction rates.

BACKGROUND: No data are available concerning the results on weight loss, correction of co-morbidities, and satisfaction rates in patients with healed gastric leak (GL) after sleeve gastrectomy (SG). OBJECTIVE: Evaluate weight loss, correction of co-morbidities, and satisfaction rate of patients with healed GL after SG. SETTING: University hospital, France, public practice. METHODS: Between March 2004 and October 2012, all patients managed for GL after SG with a minimum of 1 year follow-up were included. These patients (GL group) were matched in terms of preoperative data and type of surgical procedure (first- or second-line SG) on a 1:2 basis with 74 patients without GL (control group) selected from a population of 899 SGs. Primary endpoint was the weight change over a 1-year period after performing SG. Secondary endpoints were GL data, co-morbidities data, and satisfaction rates 1 year after SG. RESULTS: The GL group consisted of 37 patients (27 first-line SG [73%]). The mean EWL in the GL group was 52.2% and 68.8% at 6 and 12 months, whereas the mean EWL in the control group was 58.9% and 72.2%, respectively (P = .12; P = .46). No significant difference was observed between the 2 groups in terms of correction of co-morbidities. At 12 months follow-up, mean BAROS score was 6.02 in the GL group and 7.14 in the control group (P = .08). No significant difference was observed between the 2 groups in terms of the SF-36 questionnaire. CONCLUSION: Despite the morbidity associated with GL, the results on weight loss, correction of co-morbidities, and satisfaction rates were similar in patients with healed GL and in patients without GL.

Gastric Stenosis After Laparoscopic Sleeve Gastrectomy: Diagnosis and Management.

PURPOSE: The use of laparoscopic sleeve gastrectomy (LSG) is increasing worldwide. Although post-LSG gastric stenosis (GS) is less frequent, it has not been well defined and lacks standardized management procedures. The objective of the present study was to describe a series of patients with GS symptoms after LSG and to develop a standardized management procedure for this complication. METHODS: We performed a retrospective analysis of a prospective database of patients presenting with GS after LSG procedures performed between January 2008 and March 2014. The primary efficacy criterion was the frequency of post-LSG GS. GS was classified as functional (i.e. a gastric twist) or organic. The secondary efficacy criteria included the time interval between LSG and diagnosis of GS, the type of stenosis, the type of management, and the follow-up data. RESULTS: During the study period, 1210 patients underwent primary or secondary LSG. Seventeen patients had post-operative symptoms of GS (1.4%); one patient had achalasia that had not been diagnosed preoperatively and thus was excluded from our analysis. The median time interval between LSG and diagnosis of GS was 47.2 days (1-114). Eleven patients had organic GS and six had functional GS. Seven patients required nutritional support. Endoscopic treatment was successful in 15 patients (88.2%) after balloon dilatation (n = 13) or insertion of a covered stent (n = 2). Two of the 15 patients required conversion to Roux-en-Y gastric bypass (11.8%). CONCLUSION: GS after LSG is a rare complication but requires standardized management. Most cases can be treated successfully with endoscopic balloon dilatation.

Efficacy of the double-pigtail stent as a conservative treatment for grade B pancreatic fistula after pancreatoduodenectomy with pancreatogastric anastomosis.

BACKGROUND: Despite improvements in surgical techniques and postoperative care, morbidity associated with pancreatoduodenectomy (PD) is still high. Grade B pancreatic fistula (PF) requires a specific combination of radiologically guided external drainage and medical support. This treatment is effective but requires prolonged hospitalization and maintenance of external drainage. The objective of this study was to evaluate the feasibility and efficacy of a double-pigtail stent (DPS) to treat grade B PF after PD with pancreatogastric anastomosis. METHODS: Between January 2008 and October 2011, all patients who presented grade B PF after PD (n = 6) were included in the study. The PF was diagnosed according to the criteria of the International Study Group on Pancreatic Fistula. Endoscopic treatment was standardized with a DPS. The primary efficacy end point was the feasibility and efficacy of DPS placement. Secondary end points included data on the PF, the DPS placement procedure, and long-term outcome. RESULTS: Endoscopic DPS placement was achieved in all patients with no complications. The median time to onset of PF after PD was 14 days. Closure of the external PF was obtained 7 days after the introduction of the DPS. The median time to external drain removal was 7 days after DPS placement, and the median time to oral refeeding was 7 days after DPS placement for all patients. The median time to DPS removal was 60 days. The median length of hospital stay after DPS placement was 10 days. During a median follow-up period of 21 months, there was no recurrence of PF after removal of the DPS. CONCLUSION: Endoscopic treatment of grade B PF after PD appears to be effective and safe and is associated with shorter hospitalization.

Frey procedure for the treatment of chronic pancreatitis associated with common bile duct stricture.

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.

A comparative study of surgery and endoscopy for the treatment of bile duct stricture in patients with chronic pancreatitis.

BACKGROUND: This study aimed to compare the outcomes of endoscopic treatment (ET) and surgical treatment (ST) for common bile duct (CBD) stricture in patients with chronic pancreatitis (CP). METHODS: From 2004 to 2009, 39 patients (35 men and 4 women; median age, 52 years; range, 38-66 years) were referred for CBD stricture in CP. Of these 39 patients, 33 (85 %) underwent primary ET, and 6 underwent primary ST. Treatment success was defined in both groups as the absence of signs denoting recurrence, with normal serum bilirubin and alkaline phosphatase levels after permanent stent removal in ET group. The follow-up period was longer than 12 months for all the patients. RESULTS: For the patients treated with ET, the mean number of biliary procedures was 3 (range, 1-10) per patient including extractible metallic stents in 35 % and multiple plastic stents in 65 % of the patients. The mean duration of stent intubation was 11 months. The surgical procedure associated with biliary drainage (4 choledochoduodenostomies, 1 choledochojejunostomy, and 1 biliary decompression within the pancreatic head) was a Frey procedure for five patients and a pancreaticojejunostomy for one patient. The overall morbidity rate was higher in the ST group. The total hospital length of stay was similar in the two groups (16 vs 24 days, respectively; p = 0.21). In terms of intention to treat, the success rates for ST and ET did not differ significantly (83 % vs 76 %; p = 0.08). Due to failure, 17 patients required ST after ET. Event-free survival was significantly longer in the ST group (16.9 vs 5.8 months; p = 0.01). The actuarial success rates were 74 % at 6 months, 74 % at 12 months, and 65 % at 24 months in the ST group and respectively 75 %, 69 %, and 12 % in the ET group (p = 0.01). After more than three endoscopic procedures, the success rates were 27 % at 6 months and 18 % at 18 months. CONCLUSION: For bile duct stricture in CP, surgery is associated with better long-term outcomes than endoscopic therapy. After more than three endoscopic procedures, the success rate is low.
