Reconstruction options following pancreaticoduodenectomy after Roux-en-Y gastric bypass: a systematic review

Laparoscopic Pancreaticoduodenectomy After Roux-en-Y Gastric Bypass: Case Report and Literature Review

This is a case report of an alternate laparoscopic reconstruction possibility in a patient that required a cephalic duodenopancreatectomy (DPC) who previously underwent a Roux-en-Y gastric bypass (RYGB). The question of what type of reconstruction is to be performed in such patients is thoroughly debated in this article.

Comparison of reconstruction techniques after pancreatoduodenectomy: A single-center retrospective cohort study

BACKGROUND

There is controversy regarding which is the best reconstruction technique after the pancreatoduodenectomy. Currently, there are no studies comparing the three most frequent reconstruction techniques: Whipple + Roux-en-Y gastrojejunostomy (WRYGJ), pyloric-preserving + Billroth II (PPBII), and Whipple + BII (WBII).

METHODS

Between 2012 and March 2023, 246 patients underwent pancreaticoduodenectomy with the following type of reconstruction techniques: (1) WRYGJ: 40 patients; (2) PPBII: 118 patients; and (3) WBII: 88 patients. A retrospective comparative study among these groups was performed.

RESULTS

No significant differences were found among the groups regarding duration of the surgery, the blood volume transfused, or caliber of the Wirsung duct. The size and types of tumors, the degree of differentiation and tumor invasion of the peripancreatic tissue, vascular and neural structures, and lymph nodes were similar among the groups. The rate of R0 resection was lower in WBII (62.5% [55/88]) than in WRYGJ (75% [30/40]) and PPBII (72% [85/118]), but statistically insignificant among the groups (p = 0.232). The incidences of relevant B/C postoperative pancreatic fistula (POPF) were similar among the groups: 7.5% (7/40) in WRYGJ, 17% (20/118) in PPBI, and 26.2% (23/88) in WBII (p = 0.292). In addition, the incidence of B/C delayed gastric emptying (DGE) was higher in WBII (27.3% [24/88]) than in WRYGJ (20% [8/40]) and PPBII (19.5% [23/118]) but statistically insignificance among the groups (p = 0.381). The incidence of medical and surgical complications, intensive care unit and hospital stays, morbimortality at 90 days, and 5-year survival were similar among the groups. Multivariate analysis revealed that POPF grade B/C was a risk factor for DGE grade B/C (odds ratio (OR) = 9.903, 95% confidence interval (CI) = 4.829-20.310; p < 0.001), and a <3-mm Wirsung duct was a risk factor for POPF (OR = 3.604, 95% CI = 1.791-7.254; p < 0.001).

CONCLUSION

No technique was superior to the others. Only relevant POPF B/C was a risk factor for DGE B/C, and <3 mm Wirsung for a POPF.

Pancreaticoduodenectomy after Roux-en-Y gastric bypass and novel endoscopic ultrasound-directed transgastric ERCP procedure

Performing a pancreaticoduodenectomy (PD) in patients having undergone a Roux-en-Y gastric bypass (RNYGB) poses a significant surgical challenge. We present a patient with a history of RNYGB and endoscopic ultrasound-directed transgastric ERCP (EDGE) procedure who underwent a successful PD. This 77-year-old female with history of open RNYBG presented with resectable pancreatic adenocarcinoma. A preoperative EDGE procedure was required for biliary decompression. A PD was performed by removing the entire biliopancreatic limb for oncologic resection. The reconstructive technique here involved utilizing the old common channel for the hepaticojejunostomy, pancreaticojejunostomy, and remnant gastrojejunostomy. The case also included Axios stent placement during a preoperative EDGE procedure. This case describes the first reported successful PD in a patient with prior RNYGB and EDGE procedure. Although the optimal technique for this clinical scenario remains unestablished, this unique case contributes to the literature by demonstrating an effective approach for practicing surgeons.

Pancreaticoduodenectomy after endoscopic ultrasound-guided lumen apposing metal stent (LAMS): A case series evaluating feasibility and short-term outcomes

Introduction

Endoscopic ultrasound (EUS)-guided lumen-apposing metal stents (LAMS) represent a novel tool in therapeutic endoscopy. However, the presence of LAMS may dissuade surgeons from operations with curative-intent. We report three clinical scenarios with deployment of LAMS in patients that subsequently underwent pancreaticoduodenectomy (PD).

Methods

Six patients identified from our IRB-approved pancreas cancer database had EUS-LAMS placement prior to PD. Patient, tumor, treatment-related variables, and outcomes are herein reported.

Results

Two patients underwent a LAMS gastrojejunostomy (GJ) for duodenal obstruction. Another patient underwent LAMS choledochoduodenostomy (CDS) for malignant biliary obstruction. In three patients, a LAMS gastrogastrostomy or jejunogastrostomy was deployed post Roux-en-Y gastric bypass (RYGB) for a EUS-directed transgastric ERCP (EDGE) procedure. The hospital length of stay after LAMS placement was 0-3 days without morbidity. Patients subsequently proceeded to either classic PD (n = 5) or PPPD (n = 1). Interval from LAMS insertion to surgery ranged from 28 to 194 days. Mean PD operative time and EBL were 513 minutes and 560 mL, respectively. Post-PD hospital length of stay was 4-17 days. Clavien-Dindo IIIb morbidity required percutaneous drainage of intra-abdominal collections in two patients. In cases involving LAMS-GJ and CDS, the LAMS directly impacted the surgeon's preference not to perform pylorus preservation.

Conclusions

In this case series, PD following EUS-LAMS was feasible with acceptable morbidity. Additional studies with larger patient populations are needed to evaluate LAMS as a bridge to PD with curative-intent.

Total pancreatectomy, splenectomy and remnant gastrectomy for invasive intraductal papillary mucinous neoplasm (IPMN) after prior Roux-en-Y gastric bypass

A female patient in her 50s presented with abdominal pain, nausea and jaundice. She had a history of prior Roux-en-Y gastric bypass and her body mass index was 52.5 kg/m2 Biochemical testing revealed a total bilirubin level of 14.3 mg/dL (normal<1.2 mg/dL) and carbohydrate antigen 19-9 of 38.3 units/mL (normal<36.0 units/mL). CT demonstrated a 3.2 cm pancreatic head mass, biliary and pancreatic duct dilation and cystic replacement of the pancreas. The findings were consistent with a diagnosis of mixed-type intraductal papillary mucinous neoplasm (IPMN) with invasive malignancy. The patient's Roux-en-Y anatomy precluded endoscopic biopsy, and she underwent upfront resection with diagnostic laparoscopy, open total pancreatectomy, splenectomy and remnant gastrectomy with reconstruction. Pathology confirmed T2N1 pancreatic adenocarcinoma, 1/29 lymph nodes positive and diffuse IPMN. She completed adjuvant chemotherapy. IPMNs have malignant potential and upfront surgical resection should be considered without biopsy in the appropriate clinical setting.

Pancreatoduodenectomy after Roux-en-Y gastric bypass surgery: Single-center experience and literature review

BACKGROUND AND OBJECTIVE

Bariatric surgery with Roux-en-Y gastric bypass (RYGB) is widely used to treat morbid obesity and present diagnostic and therapeutic challenges in patients with pancreatic and periampullary tumors. The aim of this study was to describe diagnostic tools and challenges in performing pancreatoduodenectomy (PD) on patients with altered anatomy after RYGB.

METHODS

Patients undergoing PD after RYGB from April 2015 to June 2022 at a tertiary referral center were identified. Preoperative workup, operative techniques, and outcomes were reviewed. A literature search was performed to identify articles reporting PD in post-RYGB patients.

RESULTS

Of a total of 788 PDs, six patients had previous RYGB. The majority were women (n = 5), and median age was 59 years. The patients most commonly presented with pain (50%) and jaundice (50%) with a median of 5.5 years after RYGB. The gastric remnant was resected in all cases, and reconstruction of the pancreatobiliary drainage was achieved using the distal part of the pre-existing pancreatobiliary limb in all patients. Median follow-up was 60 months. The Clavien-Dindo grade ⩾3 complications occurred in two patients (33.3%), and 90 days mortality occurred in one patient (16.6%). The literature search revealed 9 articles reporting a total of 122 cases, specifically addressing PD after RYGB.

CONCLUSIONS

Reconstruction after PD in post-RYGB patients may be challenging. Resection of the gastric remnant and use of the pre-existing biliopancreatic limb may be a safe strategy, but surgeons should be prepared for other reconstruction options for creation of a new pancreatobiliary limb.

Laparoscopic hepatopancreaticoduodenectomy for synchronous gallbladder cancer and extrahepatic cholangiocarcinoma: a case report

Background

Hepatopancreaticoduodenectomy (HPD) is one of the most complex procedures, and it is very rarely reported. Laparoscopic HPD (LHPD) is even rarer. To date, there are only 3 reports of LHPD for locally advanced gallbladder cancer (GBC) or extrahepatic cholangiocarcinoma (ECC). This is the first report of LHPD for synchronous GBC and ECC.

Case presentation

A 75-year-old female patient complained of jaundice for 2 weeks without fever or abdominal pain. She was diagnosed with synchronous GBC and ECC. After a comprehensive preparation, she underwent a laparoscopic pancreaticoduodenectomy and resection of hepatic segments of IVb and V, and her digestive tract reconstruction followed Child’s methods. She was discharged on the 12th day postoperatively without pancreatic leakage, biliary leakage, or liver failure.

Conclusions

LHPD is safe and feasible for selected cases of GBCs or ECCs.

Pancreaticoduodenectomy after Roux-en-Y Gastric Bypass: a novel reconstruction technique

The obesity epidemic continues to increase around the world with its attendant complications of metabolic syndrome and increased risk of malignancies, including pancreatic malignancy. The Roux-en-Y gastric bypass (RYGB) is an effective bariatric procedure for obesity and its comorbidities. We describe a report wherein a patient with previous RYGB was treated with a novel reconstruction technique following a pancreaticoduodenectomy (PD). A 59-year-old male patient with previous history of RYGB was admitted with painless progressive jaundice. Imaging revealed a distal common bile duct stricture and he underwent PD. There are multiple options for reconstruction after PD in patients with previous RYGB. The two major decisions for pancreatic surgeon are: (I) resection/preservation of remnant stomach and (II) resection/preservation of original biliopancreatic limb. This has to be tailored to the patient based on the intraoperative findings and anatomical suitability. In our patient, the gastric remnant was preserved, and distal part of original biliopancreatic limb was anastomosed to the stomach as a venting anterior gastrojejunostomy. A distal loop of small bowel was used to reconstruct the pancreaticojejunostomy and hepaticojejunostomy and further distally a new jejunojejunostomy performed. The post-operative course was uneventful, and the patient was discharged on 7th day. With the increase in number of bariatric procedures performed worldwide, pancreatic surgeons should be aware of the varied surgical reconstruction options for PD following RYGB. This should be tailored to the patient and there is no "one-size-fits-all".

Surgical Outcome of Pancreaticoduodenectomy in Patients with a History of Roux-en-Y Reconstruction after Tumor Removal

BACKGROUND

The need for pancreaticoduodenectomy (PD) after Roux-en-Y (RY) reconstruction after tumor removal is expected to increase in future, but current studies on outcome are sparse. This surgery is challenging, due to intraabdominal adhesions and/or anatomical changes introduced by the previous abdominal surgery. Here, we investigated the surgical outcomes of PD after RY reconstruction following tumor removal.

METHODS

We enrolled 283 patients that underwent PD. Surgical outcomes for PD were compared between patients with or without a history of RY reconstruction after tumor removal. Outcomes were also compared between two different surgical procedures for the post-PD reconstruction.

RESULTS

Among 283 patients, 11 had a history of RY reconstruction after tumor removal (3.9%). Among these, RY reconstructions had been performed where the small intestine was anastomosed to a remnant stomach after distal gastrectomy (n = 2), to remnant stomach after proximal gastrectomy (n = 1), to the esophagus after total gastrectomy (n = 6), or to the hepatic duct after extrahepatic bile duct resection (n = 2). Surgical outcomes were not significantly different between cases with and without RY reconstructions. We identified two different reconstruction procedures after removing the periampullary tumor during PD. The surgical outcomes were not significantly different between these two reconstruction groups.

CONCLUSIONS

The surgical outcome of PD was not significantly affected by a history of RY reconstruction. Similarly, the type of reconstruction performed during PD did not significantly affect the outcome. These results could be useful when planning PD in patients with a history of RY reconstruction after tumor removal.

Ampullary stenosis and choledocholithiasis post Roux-En-Y gastric bypass: challenges of biliary access and intervention

BACKGROUND

Ampullary stenosis following Roux-en-Y gastric bypass (RYGB) is increasingly encountered. We describe cases of biliary obstruction from ampullary stenosis and choledocholithiasis to illustrate the associated diagnostic and interventional challenges with this condition.

METHODS

We reviewed medical records of patients with prior RYGB who underwent a biliary access procedure or surgery for non-malignant disease from January 2012-December 2018.

RESULTS

We identified 15 patients (4 male, 11 female; mean age 53.7 years) who had RYGB on average 11.7 years (range 1-32) years before diagnosis of biliary obstruction. Fourteen patients reported abdominal pain, 5 had nausea/emesis, 12 had elevated liver function tests, and 6 had ascending cholangitis. Mean common bile duct (CBD) diameter at presentation was 16.9 mm (range 4.0-25.0 mm). Operations included 3 transduodenal ampullectomies (2 with biliary bypass), 2 CBD explorations with stone extraction, 1 laparoscopic cholecystectomy alone, 1 Whipple procedure, 1 balloon enteroscopy with sphincterotomy, and 7 transgastric endoscopic retrograde cholangiopancreatography. All ampulla pathology was benign in patients who underwent resection. At follow-up (mean 15.4 months; range 0.23-44.5 months), 12/15 (80%) reported symptom resolution or improvement.

DISCUSSION

Ampullary stenosis after RYGB presents challenges for diagnostic evaluation and intervention, often requiring multi-disciplinary expertise. The underlying pathology remains to be elucidated.

Effects of different preoperative biliary drainage methods for resected malignant obstruction jaundice on the incidence rate of implantation metastasis: A meta-analysis

The aim of the present study was to compare the effects of percutaneous transhepatic biliary drainage (PTBD) and endoscopic biliary drainage (EBD) for resected malignant obstruction jaundice (MOJ) on the incidence rate of implantation metastasis. Databases including PubMed, EMbase, Web of Science and Cochrane Library were utilized. With reference to literature reported until January 2019, controlled clinical trials were designed to compare the effects of PTBD and EBD for MOJ on the incidence rate of implantation metastasis. Subsequently, odds ratio (OR) with 95% confidence interval (CI) was calculated with Review Manager 5.3.0 software. A total of 10 studies were enrolled in this meta-analysis, including 1,085 cases in the PTBD group and 1,379 cases in the EBD group. The results revealed that there was a significant difference in the incidence rate of implantation metastasis between the PTBD group and EBD group (OR=0.35, 95% CI: 0.23–0.53, P<0.00001). Subgroup analysis revealed that the incidence rates of both catheter-related implantation metastasis and peritoneal metastasis were lower in the EBD group (OR=0.23, 95% CI: 0.12–0.44, P<0.00001; OR=0.47, 95% CI: 0.31–0.74, P=0.0008, respectively), and the advantage of EBD was demonstrated in perihilar cholangiocarcinoma, distal cholangiocarcinoma and pancreatic carcinoma (OR=0.35, 95% CI: 0.17–0.74, P=0.006; OR=0.32, 95% CI: 0.17–0.60, P=0.0005; OR=0.27, 95% CI: 0.19–0.40, P<0.00001, respectively). In conclusion, this meta-analysis revealed the appropriate choice of preoperative biliary drainage for resected MOJ. The application of EBD reduced the incidence rate of implantation metastasis, however more evidence is required from future studies, to confirm the results.

Pancreatic Head Resection Following Roux-en-Y Gastric Bypass: Operative Considerations and Outcomes

PURPOSE

This study aimed to identify optimal management decisions for surgeons preforming pancreatic head resection on patients with altered anatomy due to a previous Roux-en-Y gastric bypass (RYGB).

METHODS

A multi-national (4), multi-center (28) collaborative of 55 pancreatic surgeons who have performed pancreatoduodenectomy or total pancreatectomy following RYGB for obesity (2005-2018) was created. Demographics, operative details, and perioperative outcomes from this cohort were analyzed and compared in a propensity-score matched analysis with a multi-center cohort of 5533 pancreatoduodenectomies without prior RYGB.

RESULTS

Ninety-six patients with a previous RYGB undergoing pancreatic head resection were assembled. Pathologic indications between the RYGB and normal anatomy cohorts did not differ. Propensity score matching of RYGB vs. patients with unaltered anatomy demonstrated no differences in major postoperative outcomes. In total 20 distinct reconstructions were employed (of 37 potential options); the three most frequent reconstructions accounted for 52.1%, and none demonstrated superior outcomes. There were no differences in outcomes observed between original biliopancreatic limb use (66.7%) and those where a secondary Roux limb was created for biliopancreatic reconstruction. Remnant stomachs were removed in 54.7% of cases, with no outcome differences between resected and retained stomachs. Venting gastrostomy tubes were used in 36.2% of retained stomachs without obvious outcome benefits. Jejunostomy tubes were used infrequently (11.7%).

CONCLUSIONS

Pancreatic head resection after RYGB is an infrequently encountered, unique and challenging scenario for any given surgeon. These patients do not appear to suffer higher morbidity than those with unaltered anatomy. Various technical reconstructive options do not appear to confer distinct benefits.

Pancreaticoduodenectomy in Patients with Previous Roux-en-Y Gastric Bypass: a Matched Case-Control Study

Little has been reported regarding outcomes of pancreaticoduodenectomy (PD) in patients with previous Roux-en-Y gastric bypass (RYGB). We performed a retrospective case-control study of patients undergoing PD after RYGB from January 2012 through July 2017 at 2 institutions. Of the 380 patients who underwent PD, 12 (3.2%) had previous RYGB. They were matched (by age, sex, diagnosis, operative approach, and year of surgery) to 36 non-RYGB patients undergoing PD (1:3 ratio). No difference was found between groups in mean operative time, length of hospitalization, or postoperative morbidity. A history of RYGB in patients with pancreatic head pathology did not delay surgical intervention. Outcomes of PD were similar for patients who did or did not have prior RYGB.
