Abstract
A 75-year-old male developed acute kidney injury KDIGO stage 3 a few weeks after Whipple surgery was performed for a distal cholangiocarcinoma. Kidney biopsy revealed oxalate nephropathy. This was attributed to post-Whipple malabsorption, poor compliance with pancreatic enzyme replacement therapy, and daily intake of vitamin C supplements. Pancreatic enzyme replacement therapy was resumed and calcium carbonate initiated, with an improvement in glomerular filtration rate. Unfortunately, due to oncological progression, best supportive care was initiated.We review the pathophysiology and conditions predisposing to secondary hyperoxaluria and oxalate nephropathy. This diagnosis should be considered among the main causes of acute kidney injury following pancreatectomy, with important therapeutic implications.

Immunocyte profiling changes in patients received epidural versus intravenous analgesia after pancreatectomy: A randomized controlled trial. J Formos Med Assoc 2024:S0929-6646(24)00148-7. [PMID: 38494360 DOI: 10.1016/j.jfma.2024.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/29/2024] [Accepted: 03/04/2024] [Indexed: 03/19/2024] Open
Abstract
BACKGROUND Perioperative immunosuppressants, such as surgical stress and opioid use may downregulate anti-cancer immunocytes for patients undergoing pancreatectomy. Thoracic epidural analgesia (TEA) may attenuate these negative effects and provide better anti-cancer immunocyte profile change than intravenous analgesia using opioid. METHODS We randomly assigned 108 adult patients undergoing pancreatectomy to receive one of two 72-h postoperative analgesia protocols: one was TEA, and the other was intravenous patient-controlled analgesia (IV-PCA). The perioperative proportional changes of immunocytes relevant to anticancer immunity-namely natural killer (NK) cells, cytotoxic T cells, helper T cells, mature dendritic cells, and regulatory T (Treg) cells were determined at 1 day before surgery, at the end of surgery and on postoperative day 1,4 and 7 using flow cytometry. In addition, the progression-free survival and overall survival between the two groups were compared. RESULTS After surgery, the proportions of NK cells and cytotoxic T cells were significantly decreased; the proportion of B cells and mature dendritic cells and Treg cells were significantly increased. However, the proportions of helper T cells exhibited no significant change. These results were comparable between the two groups. Furthermore, there were no significant differences in progression-free survival (52.75 [39.96] and 57.48 [43.66] months for patients in the TEA and IV-PCA groups, respectively; p = 0.5600) and overall survival (62.71 [35.48] and 75.11 [33.10] months for patients in the TEA and IV-PCA groups, respectively; p = 0.0644). CONCLUSIONS TEA was neither associated with favorable anticancer immunity nor favorable oncological outcomes for patients undergoing pancreatectomy.

Abstract
Despite debates regarding the safety of well-selected left-sided pancreatic cancer, minimally invasive distal pancreatosplenectomy is considered safer and more effective than open distal pancreatosplenectomy in well-selected patients. Previous studies have shown that minimally invasive surgery yields comparable oncologic outcomes to open surgery. While patients who undergo minimally invasive distal pancreatosplenectomy also experience recurrences and metastases after surgery, port-site metastasis is particularly rare. In this report, we report an extremely rare case of port-site metastasis following minimally invasive distal pancreatosplenectomy for left-sided pancreatic cancer.

Abstract
BACKGROUND Minimally invasive distal pancreatectomy (MIDP), including laparoscopic and robotic distal pancreatectomy, has gained widespread acceptance over the last decade owing to its favorable short-term outcomes. However, evidence regarding its oncologic safety is insufficient. In March 2023, a randomized phase III study was launched in Japan to confirm the non-inferiority of overall survival in patients with resectable pancreatic cancer undergoing MIDP compared with that of patients undergoing open distal pancreatectomy (ODP). METHODS This is a multi-institutional, randomized, phase III study. A total of 370 patients will be enrolled from 40 institutions within 4 years. The primary endpoint of this study is overall survival, and the secondary endpoints include relapse-free survival, proportion of patients undergoing radical resection, proportion of patients undergoing complete laparoscopic surgery, incidence of adverse surgical events, and length of postoperative hospital stay. Only a credentialed surgeon is eligible to perform both ODP and MIDP. All ODP and MIDP procedures will undergo centralized review using intraoperative photographs. The non-inferiority of MIDP to ODP in terms of overall survival will be statistically analyzed. Only if non-inferiority is confirmed will the analysis assess the superiority of MIDP over ODP. DISCUSSION If our study demonstrates the non-inferiority of MIDP in terms of overall survival, it would validate its short-term advantages and establish its long-term clinical efficacy. TRIAL REGISTRATION This trial is registered with the Japan Registry of Clinical Trials as jRCT 1,031,220,705 [ https://jrct.niph.go.jp/en-latest-detail/jRCT1031220705 ].

Robotic distal gastrectomy plus spleen-preserving distal pancreatectomy: optimal resection for simultaneous gastric cancer and intraductal papillary mucinous neoplasm of the pancreatic body. Surg Case Rep 2024; 10:38. [PMID: 38332412 PMCID: PMC10853144 DOI: 10.1186/s40792-024-01831-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2023] [Accepted: 01/27/2024] [Indexed: 02/10/2024] Open
Abstract
BACKGROUND Organ-preserving surgery has recently gained increasing attention. However, performing the surgery for duplicated gastric and distal pancreatic tumors is difficult because of procedural complexity and concerns of remnant gastric necrosis. We present the first case of simultaneous robotic distal gastrectomy plus spleen-preserving distal pancreatectomy in a patient with overlapping gastric cancer and intraductal papillary mucinous neoplasm. CASE PRESENTATION A 78-year-old man was diagnosed with gastric cancer in the middle stomach and intraductal papillary mucinous neoplasm of the pancreatic body. Radical cure surgery was performed using the da Vinci Xi robotic system. Conventional distal gastrectomy was initially completed using near-infrared ray guidance when transecting the stomach. After dividing the pancreas, the parenchyma of the distal pancreas was detached from the splenic artery and vein; multiple branches from these splenic vessels were dissected. Indocyanine green imaging confirmed sufficient blood flow in the splenic vessels and perfusion of the remnant stomach. Ultimately, gastrointestinal reconstruction was performed, and the postoperative course was uneventful. CONCLUSIONS The robotic distal gastrectomy plus spleen-preserving distal pancreatectomy procedure was safely performed. Compared to the total gastrectomy plus distal pancreatectomy with splenectomy procedure, this technique may improve the quality of dietary life, reduce weight loss, and prevent complications associated with splenectomy.

Prognostic value of margin clearance in total and distal pancreatectomy specimens with pancreatic ductal adenocarcinoma in a Danish population-based nationwide study. Pathol Res Pract 2024; 254:155077. [PMID: 38277754 DOI: 10.1016/j.prp.2023.155077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 12/27/2023] [Accepted: 12/30/2023] [Indexed: 01/28/2024]
Abstract
BACKGROUND The prognostic role of resection margin status following total (TP) and distal (DP) pancreatectomy for pancreatic ductal adenocarcinoma (PDAC) is insufficiently evaluated. In Denmark, pancreatic surgery, including the postoperative pathological examination of the resection specimens, is confined to four centres, all reporting to the Danish Pancreatic Cancer Database (DPCD). In this Danish population-based nationwide study on TP and DP for PDAC from 2015-2019, based on data from DPCD, we evaluated whether there is a prognostically relevant minimum margin clearance definition and whether certain margins hold independent prognostic information. METHODS Clinical and pathological data were retrieved from DPCD and supplemented by review of pathology reports and re-microscopy, if needed. One of the study pathologists performed all re-microscopy. The prognostic significance of margin status was evaluated by dichotomisation of the TP cohort (n = 101) and the DP cohort (n = 90) into involved and uninvolved groups, using different clearance definitions (0.5 - ≥3.0 mm). RESULTS Following TP, direct involvement of the superior mesenteric artery (SMA) margin had independent prognostic value. When using a clearance definition of ≥ 0.5 or ≥ 1.5 mm for SMA, median survival for R0 versus R1 was 19 (95% CI 14-26) versus 10 (95% CI 5-20) months (p = 0.010), and 21 (95% CI 15-30) versus 10 (95% CI 8-19) months (p = 0.011), respectively. Overall margin status was not of significant prognostic importance following neither DP nor TP. CONCLUSION In this Danish population-based nationwide study, SMA margin involvement was a significant isolated prognostic factor following TP, whereas combined assessment of all circumferential margins did not hold statistically significant prognostic information. Following DP, resection margin status did not affect survival.

Abstract
BACKGROUND AND OBJECTIVES Recurrent isolated pancreatic metastasis from Renal Cell Carcinoma (RCC) after pancreatic resection is rare. The purpose of our study is to describe a series of cases of relapse of pancreatic metastasis from renal cancer in the pancreatic remnant and its surgical treatment with a repeated pancreatic resection, and to analyse the results of both overall and disease-free survival. METHODS Multicenter retrospective study of patients undergoing pancreatic resection for RCC pancreatic metastases, from January 2010 to May 2020. Patients were grouped into two groups depending on whether they received a single pancreatic resection (SPS) or iterative pancreatic resection. Data on short and long-term outcome after pancreatic resection were collected. RESULTS The study included 131 pancreatic resections performed in 116 patients. Thus, iterative pancreatic surgery (IPS) was performed in 15 patients. The mean length of time between the first pancreatic surgery and the second was 48.9 months (95 % CI: 22.2-56.9). There were no differences in the rate of postoperative complications. The DFS rates at 1, 3 and 5 years were 86 %, 78 % and 78 % vs 75 %, 50 % and 37 % in the IPS and SPS group respectively (p = 0.179). OS rates at 1, 3, 5 and 7 years were 100 %, 100 %, 100 % and 75 % in the IPS group vs 95 %, 85 %, 80 % and 68 % in the SPS group (p = 0.895). CONCLUSION Repeated pancreatic resection in case of relapse of pancreatic metastasis of RCC in the pancreatic remnant is justified, since it achieves OS results similar to those obtained after the first resection.

Abstract
INTRODUCTION Pancreatic serous cystic neoplasm (SCN) is usually benign and is often managed using imaging surveillance if asymptomatic. It has a higher incidence in females but is rare in younger age groups. Acute hemorrhagic complications associated with SCN are infrequent. Whether asymptomatic SCN can cause acute hemorrhage, especially in women of childbearing age, is not well-established. PRESENTATION OF CASE A 30-year-old Japanese female, who was six months postpartum and under surveillance for asymptomatic pancreatic SCN, presented to the emergency department with gradually worsening left lateral abdominal pain. Regular ultrasound revealed no change in SCN size; however, no imaging surveillance had been conducted over the past two years. She had pain in the entire abdomen, which intensified around the navel and elicited guarding. Abdominal contrast-enhanced computed tomography revealed a cystic mass in the pancreatic tail with a contrast blush within the cyst and an adjacent retroperitoneal hematoma. Endovascular embolization was performed to control the hemorrhage. The patient had an uneventful medical recovery and was discharged five days after embolization. Five months after discharge, she underwent laparoscopic distal pancreatectomy and splenectomy as an elective surgery and was discharged uneventfully. DISCUSSION Even with periodic imaging surveillance, pancreatic SCN can suddenly cause spontaneous hemorrhage. Clinicians should be aware that pancreatic SCN can potentially cause life-threatening complications, including spontaneous hemorrhage. CONCLUSION We report a case of an unexpected complication with spontaneous hemorrhage in a young woman who was under imaging surveillance for pancreatic SCN. The patient was successfully treated with angioembolization and planned laparoscopic surgery.

Abstract
BACKGROUND Post-operative pancreatic fistula (POPF) is a major complication following pancreatectomy and is currently difficult to predict pre-operatively. This study aims to validate pre-operative risk factors and develop a novel combined score for the prediction of POPF in the pre-operative setting. METHODS Data were collected from 2016 to 2021 for radiologic main pancreatic duct diameter (MPD), body mass index (BMI), physical status classified by American Society of Anesthesiologists (ASA), polypharmacy, mean platelet ratio (MPR), comorbidity-polypharmacy score (CPS), and a novel Combined Pancreatic Leak Prediction Score (CPLPS) (derived from MPD diameter, BMI, and CPS) were obtained from pre-operative data and analyzed for their independent association with POPF occurrence. RESULTS In total, 166 patients who underwent pancreatectomy with pancreatic leak (Grade A, B, and C) occurring in 51(30.7%) of patients. Pre-operative radiologic MPD diameter < 4 mm (p < 0.001), < 5 mm (p < 0.001), < 6 mm (p = 0.001), BMI ≥ 25 (p = 0.009), and ≥ 30 (p = 0.017) were independently associated with the occurrence of pancreatic leak. CPLPS was also predictive of pancreatic leak following pancreatectomy on univariate (p = 0.005) and multivariate analysis (p = 0.036). CONCLUSION MPD and BMI were independent risk factors predictive for the development of pancreatic leak. CPLPS, was an independent predictor of pancreatic leak following pancreatectomy and could be used to help guide surgical decision making and patient counseling.

Abstract
BACKGROUND Laparoscopic duodenum-preserving pancreatic head resection (LDPPHR) is a surgical method used to treat benign and low-grade malignant pancreatic head tumors. This study aimed to determine the protective effect of common bile duct in LDPPHR using indocyanine green (ICG) fluorescence imaging. METHODS A retrospective analysis of 30 patients treated with LDPPHR at the Second Affiliated Hospital of Nanchang University between January 2015 and November 2022 was performed. Patients were divided into two groups based on ICG use: ICG and non-ICG. RESULTS Thirty patients received LDPPHR, 11 males and 19 females, and the age was 50.50 (M (IQR)) years (range: 19-76 years). LDPPHR was successfully performed in 27 (90 %) patients, LPD was performed in 1 (3 %) patient, and laparotomy conversion was performed in 2 (7 %) patients. One patient (3 %) died 21 days after surgery. The incidence of intraoperative bile duct injury in the ICG group was lower than that in the non-ICG group (10 % vs 60 %, P = 0.009), and the operation time in the ICG group was shorter than that in the non-ICG group (311.9 ± 14.97 vs 338.05 ± 18.75 min, P < 0.05). Postoperative pancreatic fistula occurred in 16 patients (53 %), including 10 with biochemical leakage (62.5 %), four with grade B (25 %), and two with grade C (12.5 %). Postoperative bile leakage occurred in four patients (13 %). CONCLUSIONS The ICG fluorescence imaging technology in LDPPHR helps protect the integrity of the common bile duct and reduce the occurrence of intraoperative bile duct injury, postoperative bile leakage, and bile duct stenosis.

Abstract
BACKGROUND Since 2013, North American Neuroendocrine Tumor Society (NANETS) consensus-guidelines have endorsed consideration of surgical intervention for pancreatic- neuroendocrine tumors (PNET) with liver metastases. METHODS Patients with non-functional PNET with liver only metastases from 2010 to 2019 were identified from the National Cancer Database. RESULTS 34.7% underwent surgical intervention (13% PNET resection, 2.1% surgical management of liver metastases (SMLM), 19.5% PNET resection + SMLM). In multivariable analysis, government insurance, year of diagnosis>2013, increasing primary tumor size were associated with lower rate of surgical intervention. Receiving treatment at an academic center (OR 3.59, 95%CI 1.81-7.11; P < 0.001) or integrated cancer network (OR 3.21, 95%CI 1.57-6.54; P = 0.001) was associated with a higher rate of surgical intervention. The overall rate of surgical intervention decreased from 45.7% in 2010 to 23.0% in 2019. CONCLUSION Despite guideline recommendations and the suggested survival benefits, only one-third of patients underwent surgical intervention, potentially influenced by the rising utilization of systemic therapy in the past decade.

Abstract
OBJECTIVES To investigate the efficiency of a combination of preoperative contrast-enhanced computed tomography (CECT) and carbohydrate antigen 19-9 (CA19-9) in predicting disease-free survival (DFS) after R0 resection of pancreatic ductal adenocarcinoma (PDAC). METHODS A total of 138 PDAC patients who underwent curative R0 resection were retrospectively enrolled and allocated chronologically to training (n = 91, January 2014-July 2019) and validation cohorts (n = 47, August 2019-December 2020). Using univariable and multivariable Cox regression analyses, we constructed a preoperative clinicoradiographic model based on the combination of CECT features and serum CA19-9 concentrations, and validated it in the validation cohort. The prognostic performance was evaluated and compared with that of postoperative clinicopathological and tumor-node-metastasis (TNM) models. Kaplan-Meier analysis was conducted to verify the preoperative prognostic stratification performance of the proposed model. RESULTS The preoperative clinicoradiographic model included five independent prognostic factors (tumor diameter on CECT > 4 cm, extrapancreatic organ infiltration, CECT-reported lymph node metastasis, peripheral enhancement, and preoperative CA19-9 levels > 180 U/mL). It better predicted DFS than did the postoperative clinicopathological (C-index, 0.802 vs. 0.787; p < 0.05) and TNM (C-index, 0.802 vs. 0.711; p < 0.001) models in the validation cohort. Low-risk patients had significantly better DFS than patients at the high-risk, defined by the model preoperatively (p < 0.001, training cohort; p < 0.01, validation cohort). CONCLUSIONS The clinicoradiographic model, integrating preoperative CECT features and serum CA19-9 levels, helped preoperatively predict postsurgical DFS for PDAC and could facilitate clinical decision-making. CLINICAL RELEVANCE STATEMENT We constructed a simple model integrating clinical and radiological features for the prediction of disease-free survival after curative R0 resection in patients with pancreatic ductal adenocarcinoma; this novel model may facilitate preoperative identification of patients at high risk of recurrence and metastasis that may benefit from neoadjuvant treatments. KEY POINTS • Existing clinicopathological predictors for prognosis in pancreatic ductal adenocarcinoma (PDAC) patients who underwent R0 resection can only be ascertained postoperatively and do not allow preoperative prediction. • We constructed a clinicoradiographic model, using preoperative contrast-enhanced computed tomography (CECT) features and preoperative carbohydrate antigen 19-9 (CA19-9) levels, and presented it as a nomogram. • The presented model can predict disease-free survival (DFS) in patients with PDAC better than can postoperative clinicopathological or tumor-node-metastasis (TNM) models.

Abstract
BACKGROUND Limited data comparing recovery of health-related quality of life (HRQoL) after laparoscopic (LDP) versus open distal pancreatectomy (ODP) are available. The aim of this study was to assess the impact of laparoscopy on postoperative HRQOL after DP using the Patient-Reported Outcomes Measurement Information System (PROMIS). METHODS Data from consecutive patients who underwent DP (2020-2022) enrolled in a prospective clinical trial were reviewed. Patients completed PROMIS-29 plus 2 profile preoperatively, at postoperative day (POD) 15, 30, 90, and 180. Linear regression analysis adjusting for confounders including preoperative PROMIS scores, age, gender, ASA score, diagnosis, and multivisceral resection was used to estimate mean between-group differences (MD) in postoperative PROMIS domains T scores. RESULTS Overall, 202 patients (118 laparoscopic, 86 open) underwent DP (median age 66 years, pancreatic cancer 41%, multivisceral resection 10%, median LOS 6 days). At POD15, LDP was associated with higher physical function (MD 5.6) and participation in social roles and activities scores (MD 3.8), reduced fatigue (MD - 2.7) and sleep disturbance (MD - 3.8) compared to ODP. At POD30, LDP patients had higher physical function (MD 5.2) and participation in social roles and activities scores (MD 6.0), reduced fatigue (MD - 3.5), and anxiety (MD - 4.0) compared to ODP. No between-group differences were found in HRQoL domains at POD90 and 180. Six months after surgery, the proportions of patients who had not recovered to preoperative physical function, participation in social roles and activities, fatigue, pain interference, sleep disturbance, cognitive function, depression, and anxiety were 31%, 31%, 28%, 20%, 15%, 14%, 8%, and 7%, respectively. CONCLUSIONS According to PROMIS, LDP resulted in improved physical and social functioning and reduced anxiety and fatigue up to 30 days after surgery compared to ODP. At 6 months after surgery, recovery of physical domains is still incomplete in up to 30% of patients.

Laparoscopic transverse abdominis plane block: how I do it and a cost efficiency analysis. Langenbecks Arch Surg 2023; 409:16. [PMID: 38147123 DOI: 10.1007/s00423-023-03210-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Accepted: 12/17/2023] [Indexed: 12/27/2023]
Abstract
PURPOSE To determine the efficacy and efficiency of laparoscopic transverse abdominis plane block (Lap-TAP) in patients undergoing pancreatoduodenectomy and gastrectomy compared to those of ultrasound-guided TAP (US-TAP). METHODS We retrospectively analyzed the records of patients who underwent open or minimally invasive (MIS) pancreatoduodenectomy and major gastrectomy with the use of Lap-TAP or US-TAP at our institution between November 1, 2018, and September 30, 2021. We compared the estimated time and cost associated with Lap-TAP and US-TAP. We also compared postoperative opioid use and pain scores between patients who underwent open laparotomy with these TAPs. RESULTS A total of 194 patients were included. Overall, 114 patients (59%) underwent pancreatectomy, and 80 patients (41%) underwent gastrectomy. Additionally, 138 patients (71%) underwent an open procedure, and 56 patients (29%) underwent MIS. A total of 102 patients (53%) underwent US-TAP, and 92 (47%) underwent Lap-TAP. The median time to skin incision was significantly shorter in the Lap-TAP group (US-TAP, 59 min vs. Lap-TAP, 45 min; P < 0.001), resulting in an estimated reduction in operation cost by $602. Pain scores and postoperative opioid use were similar between Lap-TAP and US-TAP among open surgery patients, indicating equivalent pain control between Lap-TAP and US-TAP. CONCLUSION Lap-TAP was equally effective in pain control as US-TAP after pancreatectomy and gastrectomy, and Lap-TAP can reduce operation time and cost. Lap-TAP is considered the preferred approach for MIS pancreatectomy and gastrectomy, which occasionally needs conversion to laparotomy.

Abstract
BACKGROUND Risk-stratified drain fluid amylase cutoff values for postoperative day 1 (POD1) (DFA1) and POD3 (DFA3) can guide early drain removal after pancreatoduodenectomy (PD). The aim of this study was to evaluate and recalibrate cutoff values instituted in Feb 2019 using a prospective sequential cohort. METHODS We performed a single-institution prospective cohort study of consecutive patients who underwent pancreatoduodenectomy following implementation of institution-specific DFA cutoffs in February 2019 through April 2022. DFA values, drain removal, and clinically relevant postoperative pancreatic fistulas (CR-POPF) were analyzed. Receiver operating characteristic (ROC) curve analysis determined optimal cutoff values. RESULTS In total, 267 patients, 173 (65%) low-risk and 94 (35%) high-risk, underwent 228 (85%) open and 39 (15%) robotic pancreatoduodenectomies. Seven (4%) low-risk patients and 21 (22%) high-risk patients developed CR-POPF. Drains were removed in 147 (55%) patients before/on POD3, with 1 (0.7%) CR-POPF. In low-risk patients, CR-POPF was excluded with 100% sensitivity if DFA1 < 286 (area under curve, AUC = 0.893, p = 0.001) or DFA3 < 97 (AUC = 0.856, p = 0.002). DFA1 < 137 (AUC = 0.786, p < 0.001) or DFA3 < 56 (AUC = 0.819, p < 0.001) were 100% sensitive in high-risk patients. Previously established DFA1 cutoffs of 100 (low-risk) and < 26 (high-risk) were 100% sensitive, while DFA3 cutoffs of 300 (low-risk) and 200 (high-risk) had 57% and 91% sensitivity. CONCLUSIONS Within a learning health system, we recalibrated post-PD drain removal thresholds to DFA1 ≤ 300 and DFA3 ≤ 100 for low-risk and DFA1 ≤ 100 and DFA3 ≤ 50 for high-risk patients. This methodology is generalizable to other centers for developing institution-specific criteria to optimize safe early drain removal.

Abstract
Pancreatic acinar cystic transformation (ACT) is a rare non-neoplastic cystic lesion that is predominantly located at the pancreatic head in females. Preoperative definitive diagnosis of ACT remains challenging despite advances in radiologic imaging methods. A 25-year-old male patient presented with abdominal discomfort and a 50-mm cystic lesion in the pancreatic tail. The patient underwent laparoscopic distal pancreatectomy, because branch duct intraductal papillary mucinous neoplasm cannot be ruled out and the presence of abdominal symptoms. The resected specimen revealed a collection of small and large cysts lined by a single cuboidal epithelium layer with scattered pancreatic tissue exhibiting fibrosis in the septal wall. The cystic lesion was epithelial, trypsin-positive, B cell lymphoma 10-positive, cytokeratin 19-positive, mucin 1-positive, and MUC6-negative with a differentiated lobular central conduit causing to an adeno-cystic cell, thereby supporting the ACT diagnosis. Distinguishing ACT from other pancreatic cystic tumors remains a diagnostic challenge despite improvements in radiologic imaging methods. Surgical resection may be justified when other cystic neoplasms cannot be excluded because of its heterogeneous nature, although the ACT is a non-neoplastic lesion, and cases of malignant transformation have never been reported to date.

J Gastrointest Surg 2023; 27:2815-2822. [PMID: 37962717 DOI: 10.1007/s11605-023-05864-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 09/29/2023] [Indexed: 11/15/2023]
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
Residual pancreatic endocrine function is important for maintaining metabolic status after pancreatectomy and is closely related to patient nutritional status and prognosis. In contrast to insulin secretion, the significance of glucagon secretion following pancreatectomy remains unclear. In this study, we assessed the changes in pancreatic glucagon secretion during pancreatectomy to determine their pathophysiological significance. We evaluated glucagon and insulin secretion using a liquid meal tolerance test before and after pancreatectomy in patients scheduled to undergo pancreaticoduodenectomy (PD) or distal pancreatectomy (DP). After pancreatectomy, fasting plasma glucagon levels were significantly decreased in both the PD (n = 10) and DP (n = 5) groups (PD: from 18.4 to 10.5 pg/mL, p = 0.037; DP: from 21.0 to 12.1 pg/mL, p = 0.043), whereas postprandial plasma glucagon levels were not changed. In the liquid meal tolerance test after pancreatectomy, 60-min plasma glucagon levels and the area under the curve (AUC) for 0-120 min of PD were significantly higher than those for DP (60-min plasma glucagon: PD 49.0 vs. DP 21.7 pg/mL, p = 0.040; AUC0-120min: PD 4,749 vs. DP 3,564 μg min/mL, p = 0.028). Postoperative plasma glucose, serum insulin, and serum C-peptide levels during the liquid meal tolerance test were not significantly different between the two groups. Although fasting plasma glucagon levels decreased, postprandial glucagon responses were maintained after both PD and DP. The difference in residual meal-stimulated glucagon response between PD and DP suggests that a relative excess of postprandial glucagon is involved in the postoperative nutritional status after PD through its impact on systemic metabolic status.

What determines complications and prognosis among patients subject to multivisceral resections for locally advanced gastric cancer? Langenbecks Arch Surg 2023; 408:442.

Abstract
BACKGROUND Locally advanced gastric cancer (GC) extending to the surrounding tissues may require a multivisceral resection (MVR) to provide the best chance of cure. However, little is known about how the extent of organ resection affects the risks and benefits of surgery. METHODS An electronic database of patients treated between 1996 and 2020 in an academic surgical centre was reviewed. MVRs were defined as partial or total gastrectomy combined with splenectomy, distal pancreatectomy, or partial colectomy. RESULTS Suspected intraoperative tumour invasion of perigastric organs (cT4b) was found in 298 of 1476 patients with non-metastatic GC, and 218 were subject to MVRs, including the spleen (n = 126), pancreas (n = 51), and colon (n = 41). MVRs were associated with higher proportions of surgical and general complications, but not mortality. A nomogram was developed to predict the risk of major postoperative morbidity (Clavien-Dindo's grade ≥ 3a), and the highest odds ratio for major morbidity identified by logistic regression modelling was found for distal pancreatectomy (2.53, 95% CI 1.23-5.19, P = 0.012) and colectomy (2.29, 95% CI 1.04-5.09, P = 0.035). Margin-positive resections were identified by the Cox proportional hazards model as the most important risk factor for patients' survival (hazard ratio 1.47, 95% CI 1.10-1.97). The extent of organ resection did not affect prognosis, but a MVR was the only factor reducing the risk of margin positivity (OR 0.44, 95% CI 0.21-0.87). CONCLUSIONS The risk of multivisceral resections is associated with the organ being removed, but only MVRs increase the odds of complete tumour clearance for locally advanced gastric cancer.

Abstract
INTRODUCTION Intraductal papillary mucinous neoplasm (IPMN) of the pancreas can progress from low-grade dysplasia to high-grade dysplasia and invasive carcinoma. METHODS In this single-center retrospective series, we analyze the clinicopathological features and long-term follow up of patients who underwent pancreatic resection for IPMN, from January 2009 to December 2019. RESULTS 31 patients were diagnosed with IPMN: 9 males and 22 females. Mean age was 67 years. Twenty-seven patients (87%) were symptomatic. Seven patients had main duct IPMN, 11 branch-type IPMN and 13 mixed-type IPMN. High-risk stigmata were found in 20 patients (64.5%) and worrisome features in 10 patients (32.2%). Thirteen patients (41.9%) had an associated invasive carcinoma, 4 (12.9%) high-grade dysplasia and 14 (45.2%) low-grade dysplasia. The follow-up was from 2 to 12 years. Median survival for patients with IPMN and associated invasive carcinoma was 45.8 months, and disease-free survival was 40.8 months. CONCLUSIONS IPMN had a higher prevalence in females, mostly symptomatic and high incidence of associated invasive carcinoma with branch type. The 5-year survival was good even with associated invasive carcinoma.

Abstract
OBJECTIVES The aim of this study was to modify recognized clinically relevant post-operative pancreatic fistula (CR-POPF) risk evaluation models with quantitative ultrasound shear wave elastography (SWE) values and identified clinical parameters to improve the objectivity and reliability of the prediction. METHODS Two prospective, successive cohorts were initially designed for the establishment of CR-POPF risk evaluation model and the internal validation. Patients who scheduled to receive pancreatectomy were enrolled. Virtual touch tissue imaging and quantification (VTIQ)-SWE was used to quantify pancreatic stiffness. CR-POPF was diagnosed according to 2016 International Study Group of Pancreatic Fistula standard. Recognized peri-operative risk factors of CR-POPF were analyzed, and the independent variables selected from multivariate logistic regression were used to build the prediction model. RESULTS Finally, the CR-POPF risk evaluation model was built in a group of 143 patients (cohort 1). CR-POPF occurred in 52/143 (36%) patients. Constructed from SWE values and other identified clinical parameters, the model achieved an area under the receiver operating characteristic curve of 0.866, with sensitivity, specificity, and likelihood ratio of 71.2%, 80.2%, and 3.597 in predicting CR-POPF. Decision curve of modified model revealed a better clinical benefit compared to the previous clinical prediction models. The models were then examined via internal validation in a separate collection of 72 patients (cohort 2). CONCLUSIONS Risk evaluation model based on SWE and clinical parameters is a potential non-invasive way to pre-operatively, objectively predict CR-POPF after pancreatectomy. CLINICAL RELEVANCE STATEMENT Our modified model based on ultrasound shear wave elastography may provide an easy access in pre-operative and quantitative evaluating the risk of CR-POPF following pancreatectomy and improve the objectivity and reliability of the prediction compared to previous clinical models. KEY POINTS • Modified prediction model based on ultrasound shear wave elastography (SWE) provides an easy access for clinicians to pre-operatively, objectively evaluate the risk of clinically relevant post-operative pancreatic fistula (CR-POPF) following pancreatectomy. • Prospective study with validation showed that the modified model provides better diagnostic efficacy and clinical benefits compared to previous clinical models in predicting CR-POPF. • Peri-operative management of CR-POPF high-risk patients becomes more possible.

Abstract
PURPOSE This study assessed the changes in malnutrition status, symptom severity, and anorexia-cachexia-related quality of life (QoL) before and after pancreatic surgery and identified significant factors associated with changes in anorexia-cachexia-related QoL in patients with operable pancreatic cancer. METHODS In total, 76 patients with pancreatic cancer who were scheduled to undergo surgery were recruited from a medical center in northern Taiwan. The Mini Nutritional Assessment, Symptom Severity Scale, and Functional Assessment of Anorexia-Cachexia Therapy scale were used to assess the patients' nutritional status, symptom severity, and anorexia-cachexia-related QoL, respectively. Bioelectrical impedance analysis was performed using X-Scan Plus II to assess body composition. A generalized estimating equation approach was used to identify significant factors associated with anorexia-cachexia-related QoL. RESULTS In total, 42.1% of the patients had malnutrition or were at risk of malnutrition before surgery. Preoperative malnutrition (β = -3.857, p = .001) and higher early satiety (β = -0.629, p = .005), insomnia (β = -0.452, p = .025), and pain (β = -0.779, p < .001) were associated with lower anorexia-cachexia-related QoL. CONCLUSION Clinicians should actively assess the nutritional status of patients with pancreatic cancer before surgery and provide symptom cluster management interventions to improve nutrition, insomnia, and pain, which is crucial for enhancing patients' anorexia-cachexia-related QoL.

Abstract
BACKGROUND Clinically relevant postoperative pancreatic fistula (CR-POPF) is a major source of morbidity after distal pancreatectomy. This study examined the association between postoperative opioid use and CR-POPF in the context of opioid-sparing postoperative care. METHODS A case-control study was performed on consecutive patients who underwent distal pancreatectomy between October 2016 and April 2022 at a single institution. Patients who developed CR-POPF were compared to controls. Multivariable regression modeling was used to identify factors associated with CR-POPF. RESULTS A total of 281 patients underwent 187 open, 20 laparoscopic, and 74 robotic-assisted operations. The rate of CR-POPF was 21% (n = 58). CR-POPF rate declined from 32 to 8% over the study period (p < 0.001). Median oral morphine equivalents (OME) administered on POD 0-1 and 0-3 were 94 and 129 mg, respectively, in patients who did not develop a fistula versus 130 and 180 mg in those who did (both p ≤ 0.001). POD 0-3 OME (OR 1.11, p = 0.044) was independently associated with increased odds of CR-POPF, with each additional 50 mg (equivalent to 10 tramadol pills) increasing the relative risk by 11% and absolute risk by 2%. CONCLUSION Early postoperative opioid use after distal pancreatectomy was associated with increased odds of CR-POPF. Decreasing perioperative opioid use through enhanced postoperative management is a low-cost and generalizable approach that may reduce rates of CR-POPF after distal pancreatectomy.

Abstract
BACKGROUND Pancreatic adenocarcinoma (PDAC) is an aggressive malignancy associated with poor outcomes. Surgical resection and receipt of multimodal therapy have been shown to improve outcomes in patients with potentially resectable PDAC; however treatment and outcome disparities persist on many fronts. The aim of this study was to analyze the relationship between rural residence and receipt of quality cancer care in patients diagnosed with non-metastatic PDAC. METHODS Using the National Cancer Database, patients with non-metastatic pancreatic cancer were identified from 2006-2016. Patients were classified as living in metropolitan, urban, or rural areas. Multivariable logistic regression was used to identify predictors of cancer treatment and survival. RESULTS A total of 41,786 patients were identified: 81.6% metropolitan, 16.2% urban, and 2.2% rural. Rural residing patients were less likely to receive curative-intent surgery (p = 0.037) and multimodal therapy (p < 0.001) compared to their metropolitan and urban counterparts. On logistic regression analysis, rural residence was independently associated with decreased surgical resection [OR 0.82; CI 95% 0.69-0.99; p = 0.039] and multimodal therapy [OR 0.70; CI 95% 0.38-0.97; p = 0.047]. Rural residence independently predicted decreased overall survival [OR 1.64; CI 95% 1.45-1.93; p < 0.001] for all patients that were analyzed. In the cohort of patients who underwent surgical resection, rural residence did not independently predict overall survival [OR 0.97; CI 95% 0.85-1.11; p = 0.652]. CONCLUSIONS Rural residence impacts receipt of optimal cancer care in patients with non-metastatic PDAC but does not predict overall survival in patients who receive curative-intent treatment.

Abstract
Pancreatic vasoactive intestinal peptide-producing tumor (VIPoma) is a rare functional neuroendocrine tumor most commonly presenting with watery diarrhea and electrolyte abnormalities that include hypokalemia, hypercalcemia and metabolic acidosis. This type of tumor has usually insidious clinical behavior that is characterized by chronic secretory diarrhea, lasting usually from months to years before diagnosis, not responsive to usual medical or dietary treatment approaches. Given the resemblance of VIPoma with other more common causes of chronic watery diarrhea, the final diagnosis is often delayed and the tumors are usually large and metastatic at the time of detection. Our case of pancreatic VIPoma demonstrates an unusual clinical course for this type of tumor with acute refractory diarrhea and rapid deterioration of patient's clinical and biochemical status that required emergent in-hospital diagnosis and treatment. Our patient is a 45-year-old woman who presented with abrupt, watery diarrhea during the past 24 h before admission accompanied with severe hypokalemia as well as hyponatremia, hyperglycemia and hypercalcemia. Despite aggressive management with fluid administration and electrolyte replenishment, no significant improvement in patient's symptoms and electrolyte imbalance was observed. After exclusion of other causes of acute diarrhea from the medical history and the laboratory tests, the clinical suspicion of a functional neuroendocrine tumor was raised. After the establishment of final diagnosis of pancreatic VIPoma with biochemical tests and magnetic resonance imaging (MRI), somatostatin analogues were prescribed and the patient underwent distal pancreatectomy and splenectomy with no signs of lymph node and splenic metastases. Few days after the surgical resection of the tumor, the patient readmitted to our hospital with tarry stools and severe anemia. The abdominal computed tomography (CT) revealed a retroperitoneal cystic lesion. The gastrointestinal bleeding gradually recessed after endoscopic hemostasis of duodenal ulcer lesions whereas the cystic lesion (postoperative lymphocele) was successfully drained under CT-guidance before discharge. After almost 10 years postoperatively, the patient is still asymptomatic with no signs of relapse or metastasis of the disease in the periodic laboratory and imaging follow-up. In conclusion, pancreatic VIPoma can sometimes manifest symptoms of abrupt onset and rapid progression that require high clinical suspicion, appropriate diagnostic workup and aggressive management.
