ABSTRACT

BACKGROUND: Weekend readmissions have been previously associated with increased mortality after pancreatic resection, but the effect of weekend discharge is less understood. In this study, we aim to determine the impact of weekend discharges on 30-day readmission rate after pancreatic surgery. METHODS: All patients who underwent pancreatic surgery at a single, high-volume institution between 2013 and 2021 were retrospectively reviewed from a targeted, institutional ACS-NSQIP database. Patients who died prior to discharge were excluded. Multivariable logistic regression was used to assess the relationship between readmission and weekend discharge. RESULTS: Out of 2042 patients who underwent pancreatectomy, 418 patients (20.5%) were discharged on the weekend. Weekend discharge was associated with fewer Whipple surgeries, fewer open surgical approaches, and shorter operative time. Patients discharged on the weekend were also less likely to have had postoperative complications such as delayed gastric emptying (DGE) (6.7% vs 12.6%, p < 0.01) and were more frequently discharged to home (91.1% vs. 85.3%, p < 0.01). Thirty-day readmission rate was almost identical between groups (14.8% vs 14.8%, p = 0.997). On multivariable analysis, 30-day readmission was independently associated with DGE (OR (95% CI): 3.48 (2.31-5.23), p < 0.01), postoperative pancreatic fistula (3.36 (2.34-4.83), p < 0.01), myocardial infarction, and perioperative blood transfusion, but not weekend discharge (1.02 (0.72-1.43), p = 0.93). Readmission rate also did not differ significantly when including Friday discharges in the weekend group (15.2% vs 14.6%, p = 0.72). CONCLUSIONS: With careful clinical decision making, patients may safely be discharged on the weekend after pancreatic surgery without increasing 30-day readmission rate.

ABSTRACT

BACKGROUND AND PURPOSE: The soft-tissue layer and facial skeleton influence the harmony and equilibrium of the face. The evaluation of the patient's structural and soft-tissue features is one of the most crucial steps in preparing for the diagnosis and treatment of oral-maxillofacial orthodontics. Clinicians can intervene with the proper treatment at the proper time to achieve the best results by being aware of the traits and variations of soft tissue at various developmental stages and in various races. To obtain a consistent treatment result in terms of function and aesthetically pleasing results, patients, and forecast, the growth that may take place after the orthopedic therapy has concluded. OBJECTIVE: To examine the soft-tissue features of the oral-maxillofacial area in Vietnamese adults (aged 18-25 years) by evaluating cephalometric radiographs. MATERIALS AND METHODS: In a cross-sectional descriptive study, 85 students from Can Tho University of Medicine and Pharmacy took part. Students' lateral cephalograms were taken in compliance with the sample requirements. RESULTS: Men's lip protrusion (4.30 ± 0.71) was higher than women's (3.88 ± 0.97) (P = 0.024 <.05) and men's (-4.88 ± 0.93) chin lip groove depth was higher than women's (-4.24 ± 0.93) (P = 0.002), both with a P value of. 05. CONCLUSIONS: The study identified a statistically significant difference in the protrusion of the top lip and the depth of the cleft lip between the male and female, demonstrating that the soft-tissue features of Vietnamese students were distinct from those of other races.

ABSTRACT

BACKGROUND AND OBJECTIVES: Modest data exist on the benefits of screening and surveillance for pancreatic cancer (PC) in high-risk individuals. Intraductal papillary mucinous neoplasms (IPMN) are known precursors to PC. We hypothesized that patients with high-risk deleterious germline mutations have a higher prevalence of IPMN. METHODS: All patients undergoing prospective screening at a single institution from 2013 to 2019 were reviewed. RESULTS: Of 1166 patients screened, 358 (31%) possessed germline mutations and/or family history of PC (mutations n = 201/358, 56%, family history n = 226/358, 63%) (median follow-up 2.7 years). IPMN was found in 127 patients (35.5%). The prevalence of IPMN in mutation carriers (18%) was higher than in the general population (p < 0.01). Germline mutation was an independent predictor of IPMN (odds ratio [OR] = 3.2; p < 0.01), while family history was not (p = 0.22). IPMN prevalence was distributed unevenly between mutation types (67%-Peutz-Jeghers; 43%-HNPCC, 24%-BRCA2; 17%-ATM; 9%-BRCA1; 0%-CDKN2A and PALB2). CONCLUSION: In this series, 18% of mutation carriers harbored IPMN, higher than the general population. Germline mutation, but not a family history of PC, was independently associated with IPMN. This prevalence varied across mutation subtypes, suggesting not all mutation carriers develop precancerous lesions. Genetic testing for patients with a positive family history may improve screening modalities for this high-risk population.

ABSTRACT

BACKGROUND: Although high-volume centers are known to have better surgical outcomes, patients with pancreatic adenocarcinoma often receive chemotherapy at treatment centers closer to home. This study aimed to determine whether treatment site of neoadjuvant therapy relative to surgery location impacts surgical timing and long-term outcomes. METHODS: All patients with pancreatic adenocarcinoma who underwent oncologic resection at a single, high-volume institution between January 2016 and February 2020 and had neoadjuvant chemotherapy before surgery were queried from a prospectively maintained database. Patients were sorted based on location of neoadjuvant chemotherapy. RESULTS: A total of 179 patients were included in the study. Seventy-four (41.3%) patients received neoadjuvant chemotherapy at the same institution as their surgery (group A), 20 (11.2%) received chemotherapy outside of their surgical institution but within the same hospital/healthcare system (group B), and 85 (47.5%) received chemotherapy at an outside location (group C). The time from completion of neoadjuvant therapy to surgery was not significantly different between groups (A vs B vs C median [interquartile range]: 34.5 [14] vs 41.5 [24] vs 36 [22] days, P = .08). Thirty-day readmission rate was lower in group A (n (%): 1 (1.4%) vs 2 (10.0%) vs 11 (12.9%), P = .02). However, the 90-day mortality and overall survival did not differ significantly between groups. CONCLUSION: Patients may receive neoadjuvant therapy at local centers without impacting surgical scheduling. Although these patients may experience higher postoperative readmission rates, perioperative mortality and long-term survival are not adversely affected by location of chemotherapy. Multidisciplinary care can be effectively practiced in different locations without affecting overall outcomes in patients with pancreatic adenocarcinoma.

ABSTRACT

BACKGROUND: Obesity is epidemic in the USA. Limited data exist examining obesity's influence on necrotizing pancreatitis (NP) disease course. METHODS: Retrospective review of prospectively maintained database of 571 adult necrotizing pancreatitis patients treated between 2007 and 2018. Patients were grouped according to body mass index (BMI) at disease onset. Patient characteristics, necrotizing pancreatitis course, and outcomes were compared between non-obese (BMI < 30) and obese (BMI > 30) patients. RESULTS: Among 536 patients with BMI data available, 304 (57%) were obese (BMI > 30), and 232 (43%) were non-obese (BMI < 30). NP etiology in the obese group was more commonly biliary (55% versus 46%, p = 0.04) or secondary to hypertriglyceridemia (10% versus 2%, p < 0.001) and less commonly alcohol (17% versus 26%, p = 0.01). Obese patients had a higher incidence of baseline comorbid disease. The CT severity index was similar between groups though obese patients had a higher rate of > 50% pancreatic gland necrosis (27% versus 19%, p = 0.02). The rates of infected necrosis and organ failure were higher among obese patients. Percutaneous drainage was more common in obese patients. Time to first necrosis intervention was earlier with increasing BMI. NP disease duration was longer in obese patients. The overall mortality rate of non-obese and obese patients did not differ. However, mortality rate increased with increasing BMI. CONCLUSION: Necrotizing pancreatitis in obese patients is characterized by a prolonged disease course, a higher risk of organ failure, infected necrosis, and the need for early necrosis-related intervention. Mortality increases with increasing BMI.

ABSTRACT

BACKGROUND: Treatment of necrotizing pancreatitis (NP) has shifted in favor of a minimally invasive step-up approach rather than early open pancreatic debridement. We hypothesized that this paradigm shift would be reflected in the intervention, morbidity, and mortality profile of NP patients. STUDY DESIGN: Single-institution retrospective review of 767 NP patients treated between 2005 and 2019. Two eras of NP intervention were identified relative to the introduction of a minimally invasive approach to NP. Patients treated between 2005 and 2010 were classified as the "early" group and compared with patients treated between 2011 and 2019, classified as the "late" group. RESULTS: In total, 299 NP patients comprised the early group and 468 patients comprised the late group. No differences were seen in patient demographics, comorbidity profile, or NP etiology between groups. Necrosis volume, necrosis location, CT severity index (CTSI), and rates of infected necrosis were similar between groups. No difference was seen in mortality. Mechanical intervention for NP was more common in the early than the late group (86% vs. 73%, p < 0.001). Time to first intervention was similar between groups (79 ± 7d vs. 75 ± 6d). The early group had higher rates of open pancreatic debridement (72% vs. 55%, p < 0.001). Endoscopic intervention was less common in the early than the late group (7% vs. 16%, p < 0.001). NP disease duration was longer in the early than the late group (223 ± 12d vs. 179 ± 7d, p = 0.001). CONCLUSION: Contemporary management of necrotizing pancreatitis is marked by less frequent operative debridement and shorter disease duration.

ABSTRACT

BACKGROUND: Postoperative pulmonary complications are a common cause of postoperative morbidity in patients undergoing hepatectomy. This study aimed to identify risk factors, define severity, and evaluate the impact of postoperative pulmonary complications on postoperative morbidity after hepatectomy. METHOD: We used a prospective database in identifying all hepatectomies from 2013 to 2018. The database was then augmented using extensive review of medical records. The Strasburg system was used in categorizing resections per complexity: major hepatic resection and minor hepatic resection, whereas the Clavien-Dindo system was used in defining postoperative pulmonary complications per severity. Potential confounders were controlled for on multiple regression models. RESULTS: A total of 702 cases were identified: major hepatic resection 413 (60%) and minor hepatic resection 289 (40%). Patients demonstrated comparable characteristics, but the postoperative pulmonary complications group was more likely to have chronic obstructive pulmonary disease (10% vs 5%; P = .02). Severe postoperative pulmonary complications among major hepatectomy was observed in 38 patients (13%). Predictors for severe postoperative pulmonary complications requiring intervention included postoperative liver failure (odds ratio = 2.8; P = .002) and biliary fistula (odds ratio = 3.5; P = .001). In addition, the occurrence of severe postoperative pulmonary complications markedly hindered recovery, increasing length of stay by 4.4-fold and readmission rates by 3-fold (P < .001). On multivariable analysis, postoperative pulmonary complications significantly increase postoperative length of stay (8 vs 5 days; P < .001) and readmission (odds ratio = 3.2; P = .001). Mortality was similar (1% vs 4%; P = .066). CONCLUSION: Postoperative pulmonary complications are a major cause of delayed recovery and worse outcomes after hepatectomy. Further, postoperative liver failure and biliary fistula can predict the occurrence of severe postoperative pulmonary complications among major hepatic resection and the associated need for readmission with these complications.

ABSTRACT

BACKGROUND: The role of concomitant gastrostomy or jejunostomy feeding tube (FT) placement during pancreatoduodenectomy (PD) and its impact on patient outcomes remain controversial. METHODS: NSQIP database was surveyed for patients undergoing PD between 2014 and 2017. FT placement was identified using CPT codes. Propensity scores were used to match the two groups (1:1) on baseline characteristics and intraoperative variables including pancreas specific ones (duct size, gland texture, underlying disease, wound class, use of wound protector, drain placement, type of pancreatic reconstruction and vascular reconstruction). Outcomes were compared. Finally, a subset analyses for patients with delayed gastric emptying (DGE) or postoperative pancreatic fistula (POPF) were performed. RESULTS: Out of 15,224 PD, 1,104 (7.5%) had FT. POPF and DGE rates were 17% and 18%, respectively, for the entire cohort. Feeding jejunostomy was the most placed FT (88.2%). Patients with FT placement were more likely to be older (mean, 65.8 vs. 64.6 y), smokers (22.6% vs. 17.8%) who had preoperative weight loss (22.5% vs. 15.3%), ASA class ≥ 3 (80.8% vs. 77.5%), preoperative transfusion (1.5% vs. 0.84%), chemotherapy (22.8% vs. 17.5%), and radiation (14.5% vs. 6.8%, p < 0.05). The matched cohort included 880 patients in each group with completely balanced preoperative and intraoperative characteristics. In the matched cohort, patients with FT placement had higher overall morbidity (52.2% vs. 44.3%, p = 0.001), major morbidity (28.4% vs. 22.5%, p = 0.004), organ/space infection (14.4% vs. 10.9%, p = 0.026), re-operation (8.6% vs. 5.1%, p = 0.003), DGE (26.8% vs. 16.4%, p < 0.001), and longer mean hospital length of stay (12.9 vs. 11.2 days, p = 0.001) than those without FT. There was no difference in mortality (1.7% vs. 2.2%, p = 0.488) or readmission rate (20.2% vs. 17.2%, p = 0.099). In patients with DGE and POPF, FT placement was not associated with morbidity, mortality, length of stay, or readmission rate (p > 0.05). CONCLUSION: Patients with FT placement during PD tend to have higher postoperative morbidity and delayed recovery.

ABSTRACT

BACKGROUND: The clinical significance of postoperative serum pancreatic enzyme elevation after pancreatoduodenectomy is understudied. We hypothesized that elevation in serum enzymes predicts morbidity and mortality after pancreatoduodenectomy. METHODS: Retrospective review of 677 patients who underwent pancreatoduodenectomy at a single institution from 2013 to 2019. Patients were categorized based on serum enzyme concentrations. Patient characteristics, drain amylase, and outcomes among groups were compared. RESULTS: In total, 415 of 677 patients had postoperative serum amylase concentrations measured. Of these, 243 (59%) were normal, 96 (23%) were classified as postoperative serum hyperamylasemia, and 76 (18%) were classified as postoperative acute pancreatitis. Major morbidity was lower among patients with normal enzyme concentration (10%) and higher in patients with postoperative serum hyperamylasemia (23%) and postoperative acute pancreatitis (18%) (P = .008). Patients with normal enzymes were less likely to develop postoperative pancreatic fistula (5%) compared with patients with postoperative serum hyperamylasemia (26%) and postoperative acute pancreatitis (21%) (P < .001) and less likely to develop delayed gastric emptying (9% vs 23% and 20%, respectively); P = .002. No difference in mortality was seen among groups. CONCLUSION: Elevated serum pancreatic enzyme concentration occurs frequently after pancreatoduodenectomy and is associated with increased postoperative morbidity. Serum enzyme concentration should be considered in management after pancreatoduodenectomy.

ABSTRACT

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

BACKGROUND: Duodenal complications of necrotizing pancreatitis (NP) are challenging and understudied. We sought to characterize the demographics and clinical course of NP patients with duodenal complications. METHODS: Single institution retrospective review of 687 NP patients treated from 2005 to 2018. RESULTS: Duodenal complications developed in 40 (6%) patients including fistula in 11 (2%) and stricture in 29 (4%) patients. Patients with duodenal complications had increased computed tomography severity index (CTSI), degree of glandular necrosis, organ failure, infected necrosis, and disease duration. Mortality from NP was increased in patients with duodenal fistula (36%) compared to patients with duodenal stricture (7%) and patients without duodenal complications (9%). Surgical management of duodenal complications was required in 9/11 (82%) patients with fistula and 17/29 (59%) patients with stricture. CONCLUSIONS: Duodenal complications occurred in 6% of necrotizing pancreatitis patients. Sixty five percent of patients with duodenal complications required surgical correction. Duodenal fistula was associated with increased mortality.

ABSTRACT

BACKGROUND: Patients with necrotizing pancreatitis (NP) have the highest rate of venous thromboembolism (VTE) of any hospitalized patient (57%). We hypothesized that VTE prophylaxis might be inadequate in the setting of this profound inflammatory disease and that early detection of deep vein thrombosis would limit pulmonary embolism. STUDY DESIGN: All patients with NP treated at a single center between August 2018 and December 2019 were enrolled in prospective, weekly VTE screening, including 4-extremity duplex ultrasound. Routine chemoprophylaxis included low-molecular-weight or unfractionated heparin. Peak serum anti-factor Xa concentration was measured during weekly screening (goal prophylaxis 0.2 to 0.4 IU/mL). RESULTS: Eighty-five patients with NP underwent a total of 201 screening events (mean 2.4 per patient). VTE developed in 55 patients (65%), including splanchnic vein thrombosis in 41 patients (48%) and extremity deep vein thrombosis (eDVT) in 32 patients (38%). Extremity DVT was diagnosed a mean ± SD of 44 ± 30 days after NP onset. Symptomatic pulmonary embolism was prevented in all patients diagnosed with eDVT and no contraindication to anticoagulation (0 of 29). Prophylactic anti-factor Xa concentration was only achieved in 21% (12 of 57 screening events); no eDVTs developed in patients achieving prophylactic anti-factor Xa concentration. CONCLUSIONS: In patients with NP, identification of eDVT by screening ultrasound permits early treatment and prevents symptomatic pulmonary embolism. Fixed dosing of chemical prophylaxis is inadequate in most patients with NP and likely contributes to the mechanism of increased VTE in NP.

ABSTRACT

BACKGROUND: Biliary fistula after pancreatoduodenectomy (PD) is associated with significant morbidity and mortality. The aim of this study was to determine the risk of early postoperative biliary fistula for developing biliary anastomotic stricture after PD. METHODS: Retrospective review of all PD performed for various indications at a single institution between 2013 and 2018. Postoperative biliary fistulae were graded according to the International Study Group of Liver Surgery (ISGLS) as grade A-C. Multivariable analysis was performed for all comparative patient subgroups. RESULTS: A total of 843 patients underwent PD for malignant (68%) and benign (32%) indications. Postoperative biliary fistula developed in 66 (8%) patients; ISGLS grade A in 29 (3%), grade B in 32 (4%), and grade C in 5 (0.6%). Ninety-day mortality was 3% (25 patients). The remaining 818 patients were evaluated with a median follow-up of 16 months (IQR, 5-32 months). Biliary anastomotic stricture developed in 41 (5%) patients at a median of 10 months (IQR, 6-18 months) postoperatively. Strictures were managed with percutaneous (27 patients, 66%) or endoscopic (14 patients, 34%) stenting. No biliary stricture required operative anastomotic revision. Postoperative biliary fistula (HR, 4.4; 95% CI, 2.0-9.9; P = 0.0002) was associated with biliary anastomotic stricture; an increased risk for biliary anastomotic stricture was seen in patients with grade A (HR, 6.4; 95% CI, 2.4-16.9; P = 0.0002) and grade B (HR, 3.6; 95% CI, 1.2-10.9; P = 0.02) postoperative biliary fistula. CONCLUSION: Postoperative biliary fistula after pancreatoduodenectomy, including clinically insignificant, transient biliary fistula, is associated with an increased risk of a late biliary anastomotic stricture requiring stenting.

ABSTRACT

BACKGROUND: Unplanned readmission rates in necrotizing pancreatitis (NP) are among the highest of any medical disease (72%). Recent work has identified several potentially preventable causes of unplanned readmission in NP. We hypothesized that intensive outpatient communication would identify developing problems and decrease unplanned hospital readmission. MATERIALS AND METHODS: A review of NP patients treated at a single institution between 2016 and 2019 compared patients 2 y before (NP-pre, 2016-2018) and 1 y after (NP-post, 2018-2019) the establishment of a dedicated pancreatitis nurse coordinator. Unplanned hospital readmission and emergency room visits were compared between groups. RESULTS: A total of 178 NP patients were treated-112 patients in the NP-pre group and 66 patients in the NP-post group. No differences between groups were observed in age, sex, comorbidities, pancreatitis etiology, NP severity, or mortality. A mean of 5.4 ± 0.2 outpatient communications per patient with the pancreatitis nurse coordinator was documented in the NP-post group. Unplanned readmission rates decreased significantly from 64% (NP-pre) to 45% (NP-post; P = 0.02). The frequency of readmission decreased from 1.6 readmissions per patient (NP-pre) to 0.8 readmissions per patient (NP-post; P = 0.001). Readmissions because of symptomatic necrosis, failure to thrive, nonnecrosis infection, and drain dysfunction decreased (P < 0.05). Overall disease duration was similar (NP-pre, 4.6 ± 0.3 mo; NP-post, 5.0 ± 0.3 mo; P = 0.4); however, the mean number of unplanned inpatient days decreased from 15.4 ± 2.2 d (NP-pre) to 7.8 ± 1.6 d (NP-post; P = 0.02). CONCLUSIONS: Improved outpatient communication identifies treatable problems and significantly decreases unplanned readmission in NP patients.

ABSTRACT

Midstream urine (MSU) culture remains the gold standard diagnostic test for confirming urinary tract infection (UTI). We previously showed that patients with chronic lower urinary tract symptoms (LUTS) below the diagnostic cutoff on MSU culture may still harbor bacterial infection and that their antibiotic treatment was associated with symptom resolution. Here, we evaluated the results of the United Kingdom's MSU culture in symptomatic patients and controls. Next, we compared the bacterial enrichment capabilities of the MSU culture with those of a 50-µl uncentrifuged culture, a 30-ml centrifuged sediment culture, and 16S rRNA gene sequencing. This study was conducted on urine specimens from 33 LUTS patients attending their first clinical appointment (mean age, 48.7 years; standard deviation [SD], 16.5 years), 30 LUTS patients on treatment (mean age, 47.8 years; SD, 16.5 years) whose symptoms had relapsed, and 29 asymptomatic controls (mean age, 40.7 years, SD, 15.7 years). We showed that the routine MSU culture, adopting the UK interpretation criteria tailored to acute UTI, failed to detect a variety of bacterial species, including recognized uropathogens. Moreover, the diagnostic MSU culture was unable to discriminate between patients and controls. In contrast, genomic analysis of urine enriched by centrifugation discriminated between the groups, generating a more accurate understanding of species richness. In conclusion, the United Kingdom's MSU protocol misses a significant proportion of bacteria, which include recognized uropathogens, and may be unsuitable for excluding UTI in patients with LUTS.

ABSTRACT

BACKGROUND/AIM: The application of minimally invasive surgery to chronic pancreatitis (CP) procedures is uncommon. Our objective was to report the safety and feasibility of the robotic approach in the treatment of surgical sequelae of CP, and provide insights into the technique, tricks, and pitfalls associated with the application of robotics to this challenging disease entity. METHODS: A retrospective review of a prospectively maintained database of patients undergoing robotic-assisted resections and/or drainage procedures for CP at the University of Pittsburgh between May 2009 and January 2017 was performed. A video of a robotic Frey procedure is also shown. RESULTS: Of 812 robotic pancreatic resections and reconstructions 39 were for CP indications. These included 11 total pancreatectomies [with and without auto islet transplantation], 8 Puestow procedures, 4 Frey procedures, 6 pancreaticoduodenectomies, and 10 distal pancreatectomies. Median age was 49, and 41% of the patients were female. The most common etiology for CP was idiopathic pancreatitis (n = 16, 46%). Median operative time was 324 min with a median estimated blood loss of 250 ml. None of the patients required conversion to laparotomy. A Clavien III-IV complication rate was experienced by 5 (13%) patients, including one reoperation. Excluding the eleven patients who underwent TP, rate of clinically relevant postoperative pancreatic fistula was 7% (Grade B = 2, Grade C = 0). No 30 or 90 day mortalities were recorded. The median length of hospital stay was 7 days. CONCLUSIONS: Use of the robotic platform is safe and feasible when tackling complex pancreatic resections for sequelae of chronic pancreatitis.

ABSTRACT

OBJECTIVES: Limited data exist comparing robotic and open approaches to pancreaticoduodenectomy (PD). We performed a multicenter comparison of perioperative outcomes of robotic PD (RPD) and open PD (OPD). METHODS: Perioperative data for patients who underwent postlearning curve PD at 8 centers (8/2011-1/2015) were assessed. Univariate analyses of clinicopathologic and treatment factors were performed, and multivariable models were constructed to determine associations of operative approach (RPD or OPD) with perioperative outcomes. RESULTS: Of the 1028 patients, 211 (20.5%) underwent RPD (4.7% conversions) and 817 (79.5%) underwent OPD. As compared with OPD, RPD patients had higher body mass index, rates of prior abdominal surgery, and softer pancreatic remnants, whereas OPD patients had a higher percentage of pancreatic ductal adenocarcinoma cases, and greater proportion of nondilated (<3 mm) pancreatic ducts. On multivariable analysis, as compared with OPD, RPD was associated with longer operative times [mean difference = 75.4 minutes, 95% confidence interval (CI) 17.5-133.3, P = 0.01], reduced blood loss (mean difference = -181 mL, 95% CI -355-(-7.7), P = 0.04) and reductions in major complications (odds ratio = 0.64, 95% CI 0.47-0.85, P = 0.003). No associations were demonstrated between operative approach and 90-day mortality, clinically relevant postoperative pancreatic fistula and wound infection, length of stay, or 90-day readmission. In the subset of 522 (51%) pancreatic ductal adenocarcinomas, operative approach was not a significant independent predictor of margin status or suboptimal lymphadenectomy (<12 lymph nodes harvested). CONCLUSIONS: Postlearning curve RPD can be performed with similar perioperative outcomes achieved with OPD. Further studies of cost, quality of life, and long-term oncologic outcomes are needed.

ABSTRACT

BACKGROUND: Hepatic arterial anomalies (HAAs) are not infrequently encountered during pancreatic resections. In view of the current emergence of the robotic platform as a safe alternative to open surgery in experienced centres, this study sought to determine the implications of HAAs on the safety and oncologic outcomes of robotic pancreaticoduodenectomy (RPD). METHODS: A prospectively maintained database of patients with HAAs who underwent RPD (RPD + HAA) at a single institution between 2008 and 2013 was retrospectively reviewed. Demographic information and perioperative outcomes of RPD were compared for patients with and without HAAs. RESULTS: A total of 142 patients underwent RPD; 112 (78.9%) did not have and 30 (21.1%) did have HAAs. The majority (90.0%) of RPDs in patients with HAAs were performed for malignant indications and all aberrant vessels were preserved without conversion to laparotomy. There were no statistically significant differences between RPD patients with and without HAAs with respect to preoperative demographics, tumour characteristics, operative metrics (operative time, estimated blood loss, conversion) and postoperative outcomes, including complications, length of stay and readmissions. Negative margin (R0) rates were similar in both groups. CONCLUSIONS: Robot-assisted pancreaticoduodenectomy is safe and feasible in patients with HAAs and has outcomes similar to those in patients with normal arterial anatomy.
