Background: Sphincter of Oddi dysfunction (SOD) is managed primarily by endoscopic sphincterotomy (ES); however, surgical transduodenal sphincteroplasty (TDS) is a treatment option for select patients. In our high-volume pancreatico-biliary practice, we have observed variable outcomes among TDS patients; therefore, we sought to determine preoperative predictors of durable improvement in quality of life. Methods: SOD patients treated by TDS between January 2006 and December 2015 were studied. The primary outcome measure was long-term changes in quality of life after sphincteroplasty. The secondary outcome measure examined postoperative outcomes, including postoperative complications, need for repeat procedures, and readmission rates. Perioperative data were abstracted, and the SF-36 quality-of-life (QoL) survey was administered. Standard statistical analysis included non-parametric methods to examine bivariate associations. Results: Eighty-eight patients had an average follow-up duration of 6.7 (± 2.9) years. Thirty (34%) patients were naïve to endoscopic therapy. Patients with prior endoscopy averaged 2.1 procedures (range 1 to 13) prior to surgery. Perioperative morbidity was 27%; one postoperative death was caused by severe acute pancreatitis. Twenty-nine (33%) patients required subsequent biliary-pancreatic procedures. QoL analysis from available patients showed that 66% were improved or much improved. With multivariable analysis including SOD type and prior endoscopic instrumentation, freedom from surgical complication was the only variable that correlated significantly with a good outcome (p < 0.02). Conclusion: Surgical transduodenal sphincteroplasty provides durable symptom management for select patients with sphincter of Oddi dysfunction. Minimizing surgical complications optimizes long-term outcomes. [ABSTRACT FROM AUTHOR]

Background: There are no studies examining the use of subhepatic drains after simultaneous resection of synchronous colorectal liver metastases (sCRLM). This study aimed to (1) describe the current practices regarding primary drain placement, (2) evaluate drain efficacy in mitigating postoperative complications, and (3) determine impact of drain maintenance duration on patient outcomes. Methods: The ACS-NSQIP targeted data from 2014 to 2017 were analyzed. Propensity score of surgical drain versus no drain cohorts was performed. Main study outcomes were mortality, major morbidity, organ/space surgical site infection (SSI), secondary drain/aspiration procedure, and any septic events. Additional univariate/multivariate logistic analyses were performed to identify associations with drain placement and duration. Major hepatectomy was defined as formal right hepatectomy and any trisectionectomy. Results: 584 combined liver and colorectal resection (CRR) cases were identified. Open partial hepatectomy with colectomy was the most common procedure (70%, n = 407). Nearly 40% of patients received surgical drains (n = 226). Major hepatectomy, lower serum albumin, and no intraoperative portal vein occlusion (Pringle maneuver) were significantly associated with drain placement (p < 0.05). In the matched cohort (n = 190 in each arm), patients with surgical drains experienced higher rates of major morbidity (30% vs 12%), organ/space SSI (16% vs 6%), postoperative drain/aspiration procedures (9% vs 3%), and sepsis/septic shock (12% vs 4%) (all p < 0.05). Patients with severely prolonged drain removal, defined as after postoperative day 13 (POD13), had higher risk of postoperative morbidity compared to those with earlier drain removal (p < 0.01). 30-day mortality rate was not significantly different between the two groups. Conclusion: Primary surgical drains were placed in a substantial percentage of patients undergoing combined resection for sCRLM. This case-matched analysis suggested that surgical drains are associated with an increase in postoperative morbidity. Postoperative drain maintenance past 13 days is associated with worse outcomes compared to earlier removal. [ABSTRACT FROM AUTHOR]

Background: The influence of bile microflora, particularly with broad antimicrobial resistance patterns, on postoperative outcomes after pancreatoduodenectomy (PD), is poorly understood. The aim of this study was to determine the influence of the microbiology of bactibilia on postoperative outcomes following PD.Methods: Intraoperative bile cultures were obtained in 162 patients undergoing PD between 2015 and 2017. Intraoperative bile cultures were analyzed and correlated with short-term outcomes after PD. Independent groups t test, Pearson's correlation, or Fisher's exact tests were performed. Hazard ratios (HR) are reported with 95% confidence intervals (CI). Statistical significance was defined as P value of < 0.05.Results: Intraoperative bile cultures were positive in 89/162 patients (55%). The most common bacteria were Enterococcus spp. (n = 48, 54%), Klebsiella spp. (n = 24, 27%), and Enterobacter spp. (n = 17, 19%). Bactibilia was not associated with increased infectious complications, postoperative pancreatic fistula (POPF), or mortality. Enterococcus and Enterobacter were associated with higher rates of incisional (HR, 6.5; 95% CI, 1.2-34.8; P = 0.03) and organ-space surgical site infection (HR, 4.9; 95% CI, 1.1-22.0; P = 0.03), respectively. No single bacterium was associated with POPF, bile leak, cholangitis, 30- or 90-day mortality.Conclusion: Bactibilia, in general, does not increase the risk of developing a postoperative complication following pancreatoduodenectomy; however, Enterococcus and Enterobacter increase the likelihood of developing incisional and organ-space surgical infections, respectively.

Background: The magnitude of risk for patients undergoing cholecystectomy with high model for end-stage liver disease (MELD) scores is poorly understood.Methods: The American College of Surgeons National Surgical Quality Improvement Program database from 2005 to 2013 was used to study patients undergoing cholecystectomy. Patients were excluded if they had choledocholithiasis or preoperative dialysis. Bivariate data analysis was performed and logistic regression modeling was conducted to calculate risk-adjusted 30-day outcomes.Results: A total of 63,464 patients were included in the study. Unadjusted mortality significantly increased as the MELD score increased in the laparoscopic (MELD = 6-10, 0.2%; 11-15, 1.1%; 16-20, 3.2%; >20, 5.8%) and open groups (MELD = 6-10, 1.5%; 11-15, 3.7%; 16-20, 8.6%; >20, 17.9%) (p-value <0.001 for both). Unadjusted morbidity also increased with MELD score increases in the laparoscopic (MELD = 6-10, 3.8%; 11-15, 9.9%; 16-20, 16.3%; >20, 22.8%) and open groups (MELD = 6-10, 18.7%; 11-15, 28.2%; 16-20, 40.7%; >20, 57.8%) (p-value <0.001 for both). Patients with ascites and high MELD scores had higher rates of mortality (laparoscopic, MELD > 20, 33.3%; open, MELD > 20, 48.5%) and morbidity (laparoscopic, MELD > 20, 66.7%; open, MELD > 20, 75.8%) across all MELD scores. After adjustment, MELD score acted as a progressive and independent predictor of morbidity and mortality.Conclusions: The MELD score is an objective and easy to calculate scoring system that independently predicts postoperative morbidity and mortality in patients undergoing cholecystectomy. Patients with ascites have substantially worse outcomes across all MELD scores. Open cholecystectomy is associated with significantly more morbidity and mortality than laparoscopic cholecystectomy across all MELD groups. [ABSTRACT FROM AUTHOR]

Introduction: Robotic colorectal surgery is being increasingly adopted. Our objective was to compare early postoperative outcomes between robotic and laparoscopic colectomy in a nationally representative sample.Methods: The American College of Surgeons National Surgical Quality Improvement Project Colectomy Targeted Dataset from 2012 to 2014 was used for this study. Adult patients undergoing elective colectomy with an anastomosis were included. Patients were stratified based on location of colorectal resection (low anterior resection (LAR), left-sided resection, or right-sided resection). Bivariate data analysis was performed, and logistic regression modeling was conducted to calculate risk-adjusted 30-day outcomes.Results: There were a total of 25,998 laparoscopic colectomies (30 % LAR's, 45 % left-sided, and 25 % right-sided) and 1484 robotic colectomies (54 % LAR's, 28 % left-sided, and 18 % right-sided). The risk-adjusted overall morbidity, serious morbidity, and mortality were similar between laparoscopic and robotic approaches in all anastomotic groups. Patients undergoing robotic LAR had a lower conversion rate (OR 0.47, 95 % CI 1.20-1.76) and postoperative sepsis rate (OR 0.49, 95 % CI 0.29-0.85) but a higher rate of diverting ostomies (OR 1.45, 95 % CI 1.20-1.76). Robotic right-sided colectomies had significantly lower conversion rates (OR 0.58, 95 % CI 0.34-0.96). Robotic colectomy in all groups was associated with a longer operative time (by 40 min) and a decreased length of stay (by 0.5 days).Conclusions: In a nationally representative sample comparing laparoscopic and robotic colectomies, the overall morbidity, serious morbidity, and mortality between groups are similar while length of stay was shorter by 0.5 days in the robotic colectomy group. Robotic LAR was associated with lower conversion rates and lower septic complications. However, robotic LAR is also associated with a significantly higher rate of diverting ostomy. The reason for this relationship is unclear. Surgeon factors, patient factors, and technical factors should be considered in future studies. [ABSTRACT FROM AUTHOR]

Background: Participation by surgical trainees in complex procedures is key to their development as future practicing surgeons. The impact of surgical fellows versus general surgery resident assistance on outcomes in pancreatoduodenectomy (PD) has not been well studied. The purpose of this study was to determine differences in patient outcomes based on level of surgical trainee.Methods: Consecutive cases of PD (n = 254) were reviewed at a single high-volume institution over a 2-year period (July 2013-June 2015). Thirty-day outcomes were monitored through the American College of Surgeon's National Surgical Quality Improvement Program (NSQIP) and Quality In-Training Initiative. Patient outcomes were compared between PD assisted by general surgery residents versus hepatopancreatobiliary fellows.Results: The hepatopancreatobiliary surgery fellows and general surgery residents participated in 109 and 145 PDs, respectively. The incidence of each individual postoperative complication (renal, infectious, pancreatectomy-specific, and cardiopulmonary), total morbidity, mortality, and failure to rescue were the same between groups.Conclusions: Patient operative outcomes were the same between fellow- and resident-assisted PD. These results suggest that hepatopancreatobiliary surgery fellows and general surgery residents should be offered the same opportunities to participate in complex general surgery procedures.

Introduction: Hepaticojejunostomy leaks are less frequent than pancreatic leaks after pancreatoduodenectomy, and the current literature suggests comparable outcomes. The purpose of this study was to determine if the hepaticojejunostomy leak adversely affected patient outcomes.Methods: Consecutive cases of pancreatoduodenectomy (n = 924) were reviewed at a single high-volume institution over an 8-year period (2006-2014).Results: Pancreaticojejunostomy leaks were identified in 217 (23%) patients and hepaticojejunostomy leaks were identified in 24 patients (3%); combined hepaticojejunostomy/pancreaticojejunostomy leaks were identified in 31 patients (3%). Those with hepaticojejunostomy leaks or combined leaks had a significantly increased risk of morbidity when compared to pancreaticojejunostomy leaks or no leak (54 and 58 vs. 34 and 24%, respectively, p < 0.05). The median length of stay was significantly greater for hepaticojejunostomy leaks or combined leaks when compared to pancreatojejunostomy leaks (17 or 14 vs. 9 days, p = 0.001) and those with no leak (17 or 14 vs. 7 days, p = 0.001). Ninety-day mortality for all patients was 3.6%. Hepaticojejunostomy leaks and combined leaks significantly increased 90-day mortality rate (17 and 32%, respectively, p < 0.05).Conclusions: Hepaticojejunostomy and combined leaks after pancreatoduodenectomy are rarer than pancreaticojejunostomy leaks; these patients are at a significantly increased risk of major morbidity and mortality.

Purpose: To compare the short-term and oncologic outcomes of patients with pancreatic ductal adenocarcinoma (PDAC) undergoing laparoscopic distal pancreatectomy (LDP) and open distal pancreatectomy (ODP).Methods: Consecutive cases of distal pancreatectomy (DP) (n = 422) were reviewed at a single high-volume institution over a 10-year period (2005-2014). Inclusion criteria consisted of any patient with PDAC by surgical pathology. Ninety-day outcomes were monitored through a prospectively maintained pancreatic resection database. The Social Security Death Index was used for 5-year survival. Two-way statistical analyses were used to compare categories; variance was reported with standard error of the mean; * indicates P value <0.05.Results: Seventy-nine patients underwent DP for PDAC. Thirty-three underwent LDP and 46 ODP. There were no statistical differences in demographics, BMI, and ASA classification. Intraoperative and surgical pathology variables were comparable for LDP versus ODP: operative time (3.9 ± 0.2 vs. 4.2 ± 0.2 h), duct size, gland texture, stump closure, tumor size (3.3 ± 0.3 vs. 4.0 ± 0.4 cm), lymph node harvest (14.5 ± 1.1 vs. 17.5 ± 1.2), tumor stage (see table), and negative surgical margins (77 vs. 87%). Patients who underwent LDP experienced lower blood loss (310 ± 68 vs. 597 ± 95 ml; P = 0.016*) and required fewer transfusions (0 vs. 13; P = 0.0008*). Patients who underwent LDP had fewer positive lymph nodes (0.8 ± 0.2 vs. 1.6 ± 0.3; P = 0.04*) and a lower incidence of type C pancreatic fistula (0 vs. 13%; P = 0.03*). Median follow-up for all patients was 11.4 months. Long-term oncologic outcomes revealed similar outcomes including distant or local recurrence (30 vs. 52%; P = 0.05) and median survival (18 vs. 15 months), as well as 1-year (73 vs. 59%), 3-year (22 vs. 21%), and 5-year (20 vs. 15%) survival for LDP and ODP, respectively.Conclusions: The results of this series suggest that LDP is a safe surgical approach that is comparable from an oncologic standpoint to ODP for the management of pancreatic adenocarcinoma.

Introduction: Aggressive en bloc resection of adjacent organs is often necessary to resect pancreatic or colonic lesions. However, it is debated whether simultaneous pancreatectomy with colectomy (P+C) is warranted as it potentially increases morbidity and mortality (MM). We hypothesized that MM would be increased in P+C, especially in cases of pancreatitis.Methods: All patients who underwent pancreatectomy (P) and simultaneous pancreatectomy with colectomy (P+C) at a high-volume center from November 2006 to 2015 were prospectively collected using ACS-NSQIP at our institution. Patients with additional multivisceral or enucleation procedures were excluded. Data were augmented to 90-day outcomes using our institutional database.Results: Forty-three patients with a mean age of 62 years (27:16 male: female) underwent P+C, accounting for 2.39% (43/1797) of pancreatectomies performed. Pancreatoduodenectomy (PD) was performed in 61% (n = 26), distal pancreatectomy (DP) in 37% (n = 16), and total pancreatectomy (TP) in 2% (n = 1) of patients. The 30- and 90-day MM were higher in P+C than P (30-day: 54 vs. 37%, p = 0.037 and 9 vs. 2%, p = 0.022; 90-day: 61 vs. 42%, p = 0.019 and 14 vs. 3%, p = 0.002). Logistical regression modeling revealed an association between 90-day mortality and colectomy (p = 0.013, OR = 3.556). When P+C MM were analyzed according to intraoperative factors, there was no significant difference according to type of pancreatectomy (PD vs. DP vs. TP), origin of primary lesion (pancreas vs. colon), surgical indication (malignant vs. non-malignant), or case status (planned colectomy vs. intraoperative decision).Conclusions: Addition of colectomy to pancreatectomy substantially increased MM. Subanalysis revealed that type of resection performed, etiology, and planning status did not account for increased risk when performing P+C. However, colectomy was found to be an independent risk factor for mortality. Therefore, patients should be informed of the risk of increased postoperative complications until a further study can identify potential patients or perioperative factors that can be used for risk stratification.

Background Recent analyses of gastrointestinal operations document that complications are a key driver of readmissions. Pancreatectomy is a high outlier with respect to readmission. This analysis sought to determine if a multifactorial approach could reduce readmissions after pancreatectomy. Study Design From 2007 to 2012, the number of patients readmitted by 30 days after pancreaticoduodenectomy, and distal and total pancreatectomy was measured. Steps to decrease readmissions were implemented independently at 1-year intervals; these efforts included strategies to reduce complications, creation of a Readmissions Team with a “discharge coach,” increased use of home health, preferred relationships with post-acute care facilities, and the adoption of “Project RED” (Re-Engineered Discharge). The ACS NSQIP was used to track 30-day outcomes for all pancreatic resections. The University HealthSystem Consortium was used to determine length of stay index. Results Over 5 years, 1,163 patients underwent proximal (66%), distal (32%), or total pancreatectomy (2%). The observed 30-day mortality was 2.9% for the study period, and the length of stay index (observed/expected days) was 1.10. Neither varied significantly over time. However, 30-day morbidity decreased from 57% to 46%, and proportion of patients with 30-day all-cause readmissions decreased from 23.0% to 11.5% (p = 0.001). Conclusions All-cause 30-day readmissions after pancreatectomy decreased without increasing length of stay. Efforts by surgeons to decrease complications and an increased emphasis on coordination of care may be useful for reducing readmissions. [ABSTRACT FROM AUTHOR]

Background: Marginal ulcer (MU) is a well-described complication of pancreatoduodenectomy (PD) whose incidence remains unclear. Gastric antisecretory medications likely attenuate the risk of marginal ulceration after PD; however, the true relationship between antisecretory medication and marginal ulceration after PD is not precisely known. The aims of this study were to document the incidence of MU after PD, identify any relationship between MU and gastric antisecretory medication, and survey current practice of MU prophylaxis among experienced pancreatic surgeons. Methods: the MEDLINE, EMBASE, Cochrane Central Registrar of Controlled Trials, and Cochrane Database of Systematic Reviews databases were searched from their inception to May 2014 for abstracts documenting ulceration after pancreatoduodenectomy. Two reviewers independently graded abstracts for inclusion in this review. Contemporary practice was assessed through a four-question survey distributed globally to 200 established pancreatic surgeons. Results: After a review of 208 abstracts, 54 studies were graded as relevant. These represented a cohort of 212 patients with marginal ulcer after PD ( n = 4794). A meta-analysis of the included references shows mean incidence of ulceration after PD of 2.5 % (confidence interval (CI) 1.8-3.2 %) with a median time to diagnosis of 15.5 months. Pylorus preservation was associated with a MU rate of 2.0 % (CI 1.0-2.9 %), while 'classic' PD procedures report an overall rate of 2.6 % (CI 1.6-3.6 %). Documented use of postoperative antisecretory medication was associated with a reduced rate of 1.4 % (CI 0.1-1.7 %). One hundred forty-four of 200 (72 %) surveys were returned, from which it was determined that 92 % of pancreatic surgeons have dealt with this complication, and 86 % routinely prescribe prophylactic antisecretory medication after PD. Conclusions: The incidence of MU after PD is 2.5 % with a median time to occurrence of 15.5 months postoperatively. Gastric antisecretory medication prescription may affect the incidence of MU. The majority of pancreatic surgeons surveyed have encountered MU after PD; most (86 %) routinely prescribe prophylactic gastric antisecretory medication. [ABSTRACT FROM AUTHOR]

Objectives Patients undergoing complex hepatopancreatobiliary ( HPB) operations are at high risk for surgical site infection ( SSI). Factors such as biliary obstruction, operative time and pancreatic or biliary fistulae contribute to the high SSI rate. The purpose of this study was to analyse whether a multifactorial approach would reduce the incidence and cost of SSI after HPB surgery. Methods From January 2007 to December 2009, 895 complex HPB operations were monitored for SSI through the American College of Surgeons National Surgical Quality Improvement Program ( ACS-NSQIP). In 2008, surgeon-specific SSI rates were provided to HPB surgeons, and guidelines for the management of perioperative factors were established. Observed SSI rates were monitored before and after these interventions. Hospital cost data were analysed and cost savings were calculated. Results Observed SSI for hepatic, pancreatic and complex biliary operations decreased by 9.6% over a 2-year period ( P < 0.03). The excess cost per SSI was US$11 462 and was driven by increased length of stay and hospital readmission for infection. Surgeons rated surgeon-specific feedback on SSI rate as the most important factor in improvement. Conclusions High SSI rates following complex HPB operations can be improved by a multifactorial approach that features process improvements, individual surgeon feedback and reduced variation in patient management.

The article presents a case study of an elder woman diagnosed with lower abdominal pain. The clinical findings of the patient reflect the presence of a bilobed aneurysm located in the proximal segment of her right saphenous vein and saphenofemoral junction. It points out that the patient has no postoperative complications. It also notes the surgical excision of aneurysm and groin exploration as the preferred treatment for the illness.

Introduction: The lack of accurate markers makes preoperative differentiation between pancreatic cancer and non-malignant head lesions clinically challenging. In this study, we investigated the incidence of benign disease in patients that underwent resection for presumed pancreatic cancer diagnosed by EUS and EUS-guided FNA.Methods: Medical records of consecutive patients who underwent pancreaticoduodenectomy at Duke University were reviewed. Demographics, clinicopathologic characteristics, preoperative imaging, EUS, EUS-guided FNA, and postoperative outcomes were analyzed.Results: Seven percent of the total 494 patients studied were found to have benign disease on postoperative pathology. Fifty-nine percent of these patients with benign disease underwent preoperative EUS. EUS was positive for a head mass in 70%, demonstrated enlarged lymph nodes in 27%, and showed signs concerning for vascular invasion in 13%. FNA was suspicious or indeterminate for cancer in 63% of patients. Postoperative complications occurred in 47% and one patient died after surgery. The overall pancreatic leak rate was 15%.Conclusions: Even with aggressive use of preoperative evaluation, there is still a small subset of patients where malignancy cannot be excluded without pancreaticoduodenectomy.

Abstract Background Cirrhosis increases the risk of perioperative mortality in gastrointestinal surgery. Though cirrhosis is sometimes considered a contraindication to pancreatoduodenectomy (PD), few data are available in this patient population. The aim of the present study is to identify predictors of outcome in cirrhotic patients undergoing PD. Methods Patients undergoing PD with biopsy-proved cirrhosis were evaluated. Primary endpoints were morbidity and mortality. Child score, MELD score, and radiographic evidence of portal hypertension (pHTN) were assessed for accuracy in preoperative risk stratification. A systematic review of the literature with meta-analysis was also performed to query morbidity and mortality of patients with cirrhosis reported to undergo PD. Results Between 2005 and 2015, 36 cirrhotic patients underwent PD; three year follow-up was complete. Median Child score was 6 (range 5–10); median MELD score was 9 (range 7–18). Perioperative (90-day) mortality was 6/36. Median survival was 37 months (range 0.2–116). MELD ≥ 10 was associated with increased mortality (4/13 vs. 2/13, p = 0.004). Irrespective of Child or MELD score, those with pHTN had poor outcomes including significantly greater intraoperative blood loss, increased incidence of major complication, and length of stay. Postoperative mortality was significantly higher with pHTN (3/16 vs. 1/13, p = 0.012). Conclusion Pancreatoduodenectomy may be considered in carefully selected cirrhotic patients. MELD ≥ 10 predicts increased risk of postoperative mortality. Specific attention should be afforded to patients with preoperative radiographic evidence of portal hypertension as this group experiences poor outcomes irrespective of MELD or Child score.
