Safety and feasibility of laparoscopic pancreaticoduodenectomy in octogenarians

IntroductionWith continued technical advances in surgical instruments and growing surgical expertise, many laparoscopic pancreaticoduodenectomies (LPDs) have been safely performed with favorable outcomes, and this approach is being used more frequently. With an increase in the life expectancy, interest in treatments for elderly patients has increased. In this study, we investigated the safety and feasibility of LPD in octogenarians.MethodsFrom September 2005 to February 2020, resectable/borderline resectable periampullary tumors (PATs) were diagnosed in 71 octogenarians at Sincheon Severance Hospital and CHA Bundang Medical Center. Patients were divided into two groups: those who underwent surgery (PD, N = 38) and those who did not (NPD, N = 33). The group that underwent surgery was further divided into two groups: those who underwent open PD (OPD, N = 19), and those who underwent LPD (LPD, N = 19). Perioperative outcomes, including long-term survival, were retrospectively compared between these groups.ResultsThere was no significant difference in age, sex, comorbidities, diagnosis, and chemo-radiotherapy between the surgery and non-surgery groups. The PD group had a better survival rate than the NPD group (p < 0.05). The baseline characteristics and postoperative outcomes were not significantly different between the OPD and LPD groups. Only three and two patients in the OPD and LPD groups had a biochemical leak (p > 0.999). There was no significant difference in overall survival and disease-free survival between the OPD and LPD groups (p = 0.816, p = 0.446, respectively).ConclusionsLPD is a good alternative for octogenarians with PAT requiring PD.     

Laparoscopic pancreaticoduodenectomy versus open pancreaticoduodenectomy for pancreatic ductal adenocarcinoma: oncologic outcomes and long-term survival

The study aimed to compare the oncologic outcomes and long-term survival of laparoscopic pancreaticoduodenectomy (LPD) and open pancreaticoduodenectomy (OPD) for patients diagnosed with pancreatic ductal adenocarcinoma (PDAC). Substantial evidence demonstrated that LPD is technically safe and feasible with perioperative outcomes equivalent to that of OPD. However, for patients with malignancy, especially PDAC, the oncologic outcomes and long-term survival of patients who underwent LPD remains to be elucidated. Studies on LPD for the treatment of PDAC published before December 25, 2018 were searched online. The oncologic outcomes (e.g., numbers of lymph nodes retrieved, negative margin (R0) resection), and long-term survival (postoperative survival from 1 to 5 year) of LPD were compared to that of ODP. After screening 1507 studies, six comparative cohort studies, which reported the oncologic outcomes and long-term survival of patients with PDAC were included. No significant difference was found between LPD and OPD regarding lymph nodes harvested (OR 1.96, 95% CI − 1.17 to 5.09, p = 0.22), R0 rate (OR 1.44, 95% CI 1.00 to 2.06, p = 0.05), number of positive lymph nodes (OR − 0.44, 95% CI − 1.06 to 0.17, p = 0.16), rate of adjuvant treatment (OR 1.04, 95% CI 0.68 to 1.59, p = 0.86) and time to adjuvant treatment (OR − 6.21, 95% CI − 16.00 to 3.59, p = 0.21). LPD showed similar 1-year (OR 1.20, 95% CI 0.87 to 1.65, p = 0.28), and 2-year survival (OR 1.25, 95% CI 0.94 to 1.66, p = 0.13) to that of OPD. The 3-year (OR 1.50, 95% CI 1.12 to 2.02, p = 0.007), 4-year (OR 1.73, 95% CI 1.02 to 2.93, p = 0.04), and 5-year survival (OR 2.11, 95% CI 1.35 to 3.31, p = 0.001) were significantly longer in LPD group. For the treatment of PDAC, the oncologic outcomes of LPD were equivalent to that of OPD; LPD seemed promising regarding the postoperative long-term survival.

Preoperative hepatic artery embolization before distal pancreatectomy plus celiac axis resection does not improve surgical results: A Spanish multicentre study

BackgroundDistal pancreatectomy with celiac axis resection (DP-CAR) is a surgical procedure with high morbidity and mortality performed in patients with locally advanced pancreatic cancer. Preoperative embolization of hepatic artery (PHAE) has been postulated as a technical option to increase resection rate.Objectivecomparison of morbidity and mortality at 90 days, operative time, hospital stay and survival between patients that performed DP-CAR with and without PHAE.MethodsObservational retrospective multicentre study. Inclusion criteria: patient operated in Spanish centers with DP-CAR for pancreatic cancer from April 2004 until 23 June 2018. Preoperative (PHAE, neodjuvant treatment), intraoperative (operative time and blood loss) and postoperative data (morbidity, hospital stay, R0 and survival) were studied. Complications were measured with Clavien classification at 90 days. Specific pancreatic complications were measured using ISGPS classifications. Data were analyzed using R version 3.1.3 (http://www.r-project.org). Level of significance was set at 0.05.Results41 patients were studied. 26 patients were not embolized (NO-PHAE group) and 15 patients received PHAE. Preoperative BMI and percentage of neoadjuvant chemotherapy were the only preoperative variables different between both groups. The operative time in the PHAE group was shorter (343 min) than in the non-PHAE group (411 min) (p < 0.06). Major morbidity (Clavien > IIIa) and mortality at 90 days were higher in the PHAE group than in the non-PHAE group (60% vs 23% and 26.6% vs 11.6% respectively) (p < 0.004). No statistical difference in overall survival was observed between both groups (p = 0.14).ConclusionIn our study PHAE is not related with less postoperative morbidity. Even more, major morbidity (Clavien III-IV) and mortality was higher in PHAE group.     

Prognostic Factors After Resection of Pancreatic Cancer

Objectives  The purpose of this study was to identify important prognostic factors related to the status of a pancreatic tumor, its treatment, and the patient’s general condition. Methods  Between April 1992 and December 2006, 140 patients underwent a pancreatic resection for invasive ductal carcinoma. Prognostic factors were defined by univariate and multivariate analyses. Results  The study included 103 tumors in the head of the pancreas and 37 tumors in the body or tail. The median survival time and the actuarial 5-year survival rate for all patients were 14.5 months and 12.3%, respectively. Using the significant prognostic factors identified by univariate analysis, multivariate analysis revealed that a preoperative serum CA19-9 concentration >100 U/ml (HR = 1.84, p = 0.0074), a tumor size >3 cm (HR = 1.74, p = 0.0235), venous involvement (HR = 2.39, p = 0.0006), a transfusion requirement of ≥1000 ml (HR = 2.23, p = 0.0006), and a serum albumin concentration on 1 postoperative month (1POM) < 3 g/dl (HR = 2.40, p = 0.0009) were significant adverse prognostic factors. The presence of hypoalbuminemia on 1POM significantly correlated with a longer surgical procedure (p = 0.0041), extended nerve plexus resection around the superior mesenteric artery (p = 0.0456), and a longer postoperative hospital stay (p = 0.0063). Conclusion  To improve long-term survival, preserving the patient’s general condition by performing a curative resection with a short operation time and minimal blood loss should be the most important principle in the surgical treatment of pancreatic cancer.     

Thoracic sarcopenia predicts clinical outcomes in patients undergoing coronary artery bypass grafting: A 6-year cohort study

BackgroundThe relationship between thoracic sarcopenia and clinical outcomes in patients underwent coronary artery bypass grafting (CABG) is unclear. This study aims to evaluate whether thoracic sarcopenia has a satisfactory prognostic effect on adverse outcomes after CABG.MethodsFrom December 2015 to May 2021, 338 patients who underwent isolated CABG at our institution were recruited in this study. Skeletal muscle area at T12 level acquired by chest computed tomography (CT) was normalized to assess thoracic sarcopenia. Univariate and multivariate analyses were performed to evaluate the risk factors of postoperative complications and overall survival (OS).ResultsThe prevalence of thoracic sarcopenia in patients underwent CABG was 13.02%. The incidence of total major complication was significantly higher in thoracic sarcopenia group (81.8% vs 61.9%, p = 0.010). Thoracic sarcopenic patients also had longer postoperative hospital stays (p = 0.047), intensive care unit (ICU) stays (p = 0.001), higher costs (p = 0.001) and readmission rates within 30 days of discharge (18.2% vs 4.4%, p = 0.001). Patients without thoracic sarcopenia showed significantly higher OS at the 2-year follow-up period (93.9% vs 72.7%, p<0.001). Multivariate analyses demonstrated that thoracic sarcopenia was significantly and independently associated with postoperative complications and long-term OS after CABG.ConclusionThoracic sarcopenia is an effective clinical predictor of adverse postoperative complications and long-term OS in patients underwent CABG. Thoracic sarcopenia based on chest CT should be included in preoperative risk assessment of CABG.     

Short and long-term outcomes of minimally invasive central pancreatectomy: Comparison with minimally invasive spleen-preserving subtotal distal pancreatectomy

BackgroundCentral pancreatectomy(CP) is more complex surgery and higher complication rate than distal pancreatectomy(DP). However, with the development of minimally invasive surgery, CP has become a safer surgery technique. In this study, we compare minimally invasive CP(MI-CP) and Minimally invasive spleen-preserving subtotal DP(MI-SpSTDP) to figure out the short-term and long-term outcomes of MI-CP.MethodsFrom March 2007 to June 2020, 36 cases of MI-SpSTDP and 23 cases of MI-CP were performed for benign and borderline malignant pancreatic tumors in Severance hospital. The occurrence of postoperative pancreatic fistula(POPF) and Clavian-Dindo classification grade 3 or more in the two group was investigated, and the Controlling nutritional status scores(CONUT score) before and 1-year after surgery were compared to determine the long-term outcomes of exocrine function.ResultsThere was no difference in postoperative complications including POPF between the two groups(17.4% vs 5.1%, p = 0.294). And there were no statistical differences in either the MI-CP group (0.74 ± 0.75 vs. 0.78 ± 0.99, p = 0.803) or the MI-SpSTDP group (0.86 ± 0.83 to 0.61 ± 0.59, p = 0.071).ConclusionsMI-CP had longer operation time and hospital stay and is safe and effective in preserving endocrine and exocrine functions in treatment of benign or borderline tumors located at the neck or proximal body of the pancreas.     

Preoperative cholangitis is an independent risk factor for mortality in patients after pancreatoduodenectomy for pancreatic cancer

ObjectivesPreoperative biliary stenting is required for patients with obstructive jaundice from pancreatic adenocarcinoma who are receiving neoadjuvant chemotherapy. While in most patients this approach results in durable biliary drainage, some patients develop cholangitis during neoadjuvant treatment. Further, several studies have shown that preoperative cholangitis in patients with hepatobiliary malignancies can result in substantially unfavorable outcomes. The aim of this study was to evaluate the impact of preoperative cholangitis in patients who underwent pancreaticoduodenectomy after completing neoadjuvant chemotherapy.MethodsParticipants: all adult patients (n = 449) diagnosed with pancreatic adenocarcinoma from January 1st, 2013 to March 31st, 2018 who pursued treatment at the Massachusetts General Hospital were screened. Of these 449 patients, 97 met final inclusion criteria of receiving neoadjuvant chemotherapy with intent to pursue curative surgery. Data were collected via retrospective chart review including baseline characteristics, survival, episodes of preoperative cholangitis, and surgical complications.ResultsIn patients completing successful pancreaticoduodenectomy surgery, preoperative cholangitis is associated with increased mortality (HR 2.67, 95% CI:1.16–6.13). This finding is independent of postoperative outcomes or tumor recurrence rate. The presence of cholangitis did not impact completion of neoadjuvant chemotherapy (92% vs 85%, p = 0.5) or ability to proceed to surgery (76% vs 75%, p = 1.0). Preoperative cholangitis was not associated with postoperative morbidity (42.1% vs 45.1%, p = 1.0).ConclusionsOne episode of cholangitis during neoadjuvant chemotherapy is associated with increased mortality following successful pancreaticoduodenectomy, independent of immediate postoperative outcomes or tumor recurrence. Preoperative cholangitis does not affect ability to pursue neoadjuvant chemotherapy or complete successful surgery. Patients who develop cholangitis during the neoadjuvant chemotherapy treatment phase may reflect a distinct phenotype of patients with PDAC with a complex and more challenging clinical course.     

The impact of long-term corticosteroid use on acute postoperative complications following lumbar decompression surgery

BackgroundCorticosteroids have a negative impact on the human immune system’s ability to function at an optimal level. Studies have shown that patients on long-term corticosteroids have higher infection rates. However, the rates of infection and other complications following lumbar decompression surgery remains under-investigated. The aim of our study was to determine the impact of preoperative long-term corticosteroid usage on acute, 30-day postoperative complications in a subset of patients undergoing lumbar spine decompression surgery, without fusion or instrumentation. We hypothesize that patients on long-term corticosteroids will have higher rates of infection and other postoperative complications after undergoing lumbar decompression surgery of the spine.MethodsA retrospective cohort study was conducted using data collected from the National Surgical Quality Improvement Program database data from 2005 to 2016. Lumbar decompression surgeries, including discectomies, laminectomies, and others were identified using CPT codes. Chi-square analysis was used to evaluate differences among the corticosteroid and non-corticosteroid groups for demographics, preoperative comorbidities, and postoperative complications. Logistic regression analysis was done to determine if long-term corticosteroid use predicts incidence of postoperative infections following adjustment.Results26,734 subjects met inclusion criteria. A total of 1044 patients (3.9%) were on long-term corticosteroids prior to surgical intervention, and 25,690 patients (96.1%) were not on long-term corticosteroids. Patients on long-term corticosteroids were more likely to be older (p < 0.001), female (p < 0.001), nonsmokers (p < 0.001), and have a higher American Society of Anesthesiologist class (p < 0.001). Multivariate analysis demonstrated that long-term corticosteroid usage was associated with increased overall complications (odds ratio [OR]: 1.543; p < 0.001), and an independent risk factor for the development of minor complications (OR: 1.808; p < 0.001), urinary tract infection (OR: 2.033; p = 0.002), extended length of stay (OR: 1.244; p = 0.039), thromboembolic complications (OR: 1.919; p = 0.023), and sepsis complications (OR: 2.032; p = 0.024).ConclusionLong-term corticosteroid usage is associated with a significant increased risk of acute postoperative complication development, including urinary tract infection, sepsis and septic shock, thromboembolic complications, and extended length of hospital stay, but not with superficial or deep infection in patients undergoing lumbar decompression procedures. Spine surgeons should remain vigilant regarding postoperative complications in patients on long-term corticosteroids, especially as it relates to UTI and propensity to decompensate into sepsis or septic shock. Thromboembolic risk attenuation is also imperative in this patient group during the postoperative period and the surgeon should weigh the risks and benefits of more intensive anticoagulation measures.     

Preoperative versus postoperative chemoradiotherapy for locally advanced rectal cancer: Outcomes of survival,toxicity, sphincter preserving and prognostic factors

BackgroundThis study aimed to compare preoperative chemoradiotherapy (CRT) with postoperative CRT regarding survival, local control, disease control, sphincter preservation, toxicity and also prognostic factors for the treatment of locally advanced rectal cancer.MethodsRecords of 140 patients with locally advanced rectal cancer who received preoperative or postoperative CRT were analyzed retrospectively. We compared the treatment groups (preoperative vs postoperative) according to baseline characteristics (demographic and rectal cancer disease characteristics), and also carried out the survival analyses.ResultsFrom January 2010 to December 2019, 140 patients were included in the analysis, 65 received preoperative treatment and 75 postoperative treatment. There was no difference in survival, recurrence or distant metastasis rate in both treatment groups. The ratios of the failure to complete adjuvant chemotherapy (32% vs 4.6%) and acute grade 3–4 toxicity (32% vs 6.2%) were higher in the postoperative group (p < 0.001). In lower located tumors (≤5 cm from anal verge) the ratio of the sphincter preserving in the preoperative group was 60.7% (n = 17/28), and was 16.6% (n = 3/18) in the postoperative group (Yates χ2 = 5.829, p = 0.005).ConclusionThis study showed no difference in recurrence and survival rate. Preoperative CRT is the preferred treatment for patients with locally advanced rectal cancer, given that it is associated with a superior overall treatment compliance rate, reduced toxicity, and an increased rate of sphincter preservation in low-lying tumors, but not for overall survival.     

Venous resection for adenocarcinoma of head of pancreas: Does extent of portal vein resection affect outcomes?

BackgroundVenous resection with pancreaticoduodenectomy (PD) increases resectability rates in patients with adenocarcinoma of head of pancreas. The effect of extent of portal vein resection on perioperative morbidity and mortality is less clear. This retrospective cohort study compares results of PD with and without venous resection and explores the influence of extent of vein resection on perioperative morbidity and mortality.MethodsTotal 96 patients underwent standard PD (PD) and 20 patients had en bloc venous resections (VR). VR group was divided into segmental (VR-S) (6/20 patients) and tangential (VR-T) (14/20 patients) groups based on segmental or tangential type of venous resections. The groups were compared for morbidity, mortality and survival.ResultsPD and VR groups had comparable perioperative morbidity (p = 0.140) and mortality (p = 0.358) with a significantly higher operative time in VR (p < 0.001). Perioperative morbidity and mortality were similar in VR-S and VR-T groups (p = 0.690 and p = 0.157 respectively). Operative time and estimated blood loss were significantly higher in VR-S group over VR-T (p = 0.019 and p = 0.002 respectively). Median survival was similar for PD and VR (15 and 15.5 moths respectively; p = 0.278) and VR-S and VR-T groups (17 and 12.5 months respectively; p = 0.550). Expected blood loss and operative time were found to be independent predictors of morbidity.ConclusionsVenous resection with PD is associated with morbidity, mortality and overall survival comparable to that after standard resection. The extent of venous resection does not seem to affect perioperative morbidity and mortality.     

Characterization of postoperative acute pancreatitis (POAP) after distal pancreatectomy

BackgroundPostoperative acute pancreatitis has recently been reported as a specific complication after pancreatoduodenectomy. The aim of this study was to characterize postoperative acute pancreatitis after distal pancreatectomy.MethodsWe analyzed the outcomes retrospectively of 368 patients who underwent distal pancreatectomies during the period January 2016 to December 2019. Postoperative acute pancreatitis was defined as an increase of serum amylase activity greater than our laboratory normal upper limit on postoperative days 0 to 2. We assessed the incidence of postoperative acute pancreatitis after distal pancreatectomy and examined possible predictors of postoperative acute pancreatitis and relationships of postoperative acute pancreatitis with postoperative pancreatic fistula.ResultsThe rates of postoperative acute pancreatitis and postoperative pancreatic fistula after distal pancreatectomy were 67.9% and 28.8%, respectively. Patients who developed postoperative acute pancreatitis experienced an increased rate of severe morbidity (18.4 vs 9.3%; P = .030). Neoadjuvant therapy (odds ratio 0.28, 0.09–0.85; P = .025), age ≥ 65 y (odds ratio 0.34, 0.13–0.85; P = .020), duct size (odds ratio 0.02, 0.002–0.47; P = .013), pancreatic thickness (odds ratio 3.4, 1.29–8.9; P = .013), resection at the body-tail level (odds ratio 4.3, 1.15–23.19; P = .041), and neuroendocrine histology (odds ratio 1.14, 1.06–3.90; P = .013) were independent predictors of postoperative acute pancreatitis. Furthermore, postoperative acute pancreatitis was an independent predictor of postoperative pancreatic fistula (odds ratio 5.8, 2.27–15.20; P < .001). Postoperative pancreatic fistula occurred in 37% of patients who developed postoperative acute pancreatitis. Patients developing postoperative acute pancreatitis alone demonstrated a statistically significantly increased rate of biochemical leakage and bacterial contamination in the peripancreatic drainage fluid.ConclusionPostoperative acute pancreatitis is a frequent event after distal pancreatectomy and, despite its close association with postoperative pancreatic fistula, evidently represents a separate phenomenon. A universally accepted definition of postoperative acute pancreatitis that applies to all types of pancreatic resections is needed, because it may identify patients at greater risk for additional morbidity immediately after pancreatic resections.     

Vascular resection during pancreatectomy for pancreatic head cancer: A technical issue or a prognostic sign?

BackgroundThere is an increased interest in venous vascular resection associated with pancreatic resection for pancreatic ductal adenocarcinoma as an upfront procedure or after neoadjuvant treatment. The aim of this study was to evaluate the impact of venous vascular resection for pancreatic ductal adenocarcinoma on postoperative and long-term outcomes.MethodsThe study is a retrospective analysis of patients who underwent pancreatectomy for pancreatic head pancreatic ductal adenocarcinoma with and without venous vascular resection between January 2010 and April 2018. The impact of venous vascular resection on postoperative and pathologic data was analyzed. Univariate and multivariate analyses of predictors of disease-free and disease-specific survival were analyzed for the entire cohort. A propensity-score matched cohort analysis was subsequently performed to remove selection bias and improve homogeneity.ResultsFour hundred and eighty-one patients were included, and 126 (26%) underwent a venous vascular resection. Patients undergoing venous vascular resection had higher morbidity (64% vs 54%; P = .026) with no differences in 90-day postoperative mortality (3.1 vs 2.8%; P = .5). Venous vascular resections were also significantly associated with R1 resections (52% vs 37%; P = .002) and perineural invasion (87% vs 77%; P = .017). Five-year disease-free survival in patients with and without venous vascular resection were 7% and 20% (P = .018), respectively. Independent predictors of worse disease-free survival included venous vascular resection, positive lymph node status, and perineural invasion. Independent predictors of worse disease-specific survival were perineural invasion and positive nodal status, while adjuvant treatment was a protective factor. Five-year disease-specific survival in patients with and without venous vascular resection were 19% and 35% (P = .42).ConclusionPancreatectomy with venous vascular resection can be accomplished safely. Venous vascular resections are associated with poor prognostic factors and with a worse clinical outcome, being a significant predictor of cancer recurrence.     

Prognostic significance of pancreatic fistula and postoperative complications after pancreaticoduodenectomy in patients with pancreatic ductal adenocarcinoma

BackgroundThe influence of postoperative complications, specifically, pancreatic fistula (PF), on long-term oncologic outcome in patients with pancreatic ductal adenocarcinoma (PDAC) is unclear.MethodsProspectively collected data of patients who underwent pancreaticoduodenectomy (PD) for PDAC between 2008 and 2016 were retrospectively reviewed and analyzed. Deaths within 90 days were excluded. Median follow-up time was 22 months for the entire cohort (range 2–102 months). PF was graded as biochemical leak, grade B, or grade C according to the criteria of the International Study Group on Pancreatic Fistula. Postoperative complications were graded according to the Clavien-Dindo classification (CDC). Data on clinical and pathological characteristics as well as on recurrence and survival were collected.ResultsTwenty-nine of the 148 identified patients (19%) developed PF, of whom 17 (11.4%) had a PF grade B or C. 29 patients developed a postoperative complication CDC grade 3 or 4. The respective 3-year disease-free survival was 15.5% and 19.2% (P = 0.725), and the 5-year overall survival was 20% and 16% (P = 0.914) in patients with and without PF. On multivariate analysis, the use of adjuvant chemotherapy, lymph node involvement, surgical margin involvement, and tumor grade were associated with patient survival. PF and postoperative complications CDC grade 3 or 4 were not associated with decreased long-term survival, disease-free survival or local recurrence rate.ConclusionsWhile acknowledging the limited sample size, no association was seen between PF or postoperative complications and overall or disease-free survival in patients undergoing PD for PDAC.     

Outcomes after resection versus non-resection management of penetrating grade III and IV pancreatic injury: A trauma quality improvement (TQIP) databank analysis

BackgroundHigh-grade traumatic pancreatic injuries are associated with significant morbidity and mortality. Non-resection management is associated with fewer complications in pediatric patients. The present study evaluates outcomes following resection versus non-resection management of severe pancreatic injury caused by penetrating trauma.MethodsA retrospective study of the Trauma Quality Improvement Program (TQIP) database was performed from 1/2010 to 12/2014. Patients with AAST Organ Injury Scale pancreatic grade III and IV injuries caused by penetrating trauma were included in the study. Demographics, vital signs on admission, Abbreviated Injury Scale per body region, Injury Severity Score, transfusion and therapeutic modality were obtained. Mortality, length of stay (LOS), pseudocyst, pancreatitis, sepsis, thromboembolism, renal failure, ARDS and unplanned ICU admission or re-operation were stratified according to injury grade and treatment modality. Patients were stratified into those who did/did not undergo pancreatic resection.ResultsA total of 4,098 patients had a pancreatic injury of which 15.9% (n = 653) had a grade III and 6.7% (n = 274) a grade IV pancreatic injury. There were no differences in patient demographics or overall injury severity between the resected and non-resected cohorts within each pancreatic injury grade. Forty-two percent of grade III and 38.0% of grade IV injuries underwent pancreatic resection. The total LOS was longer in the resection arm irrespective of pancreatic injury severity. There was no significant difference in morbidity between cohorts. Similarly, mortality was not significantly different between the two management approaches for grade III: 15.1% (95% CI 11.0–19.9) vs. 18.4% (95% CI 14.6–22.6), p = 0.32 and grade IV: 24.0% (95% CI: 16.2–33.4) vs. 27.1% (95% CI: 20.5–34.4), p = 0.68.ConclusionResection for treatment of grade III and IV pancreatic injury is not associated with a significant decrease in mortality but is associated with an increase in hospital LOS.     

Clinical significance of postoperative acute pancreatitis after pancreatoduodenectomy and distal pancreatectomy

BackgroundThe definition of postoperative acute pancreatitis as a specific complication of pancreatic surgery was proposed in 2016. Its presence and relevance have not been established, especially after a distal pancreatectomy.MethodsMedical records of 319 patients who underwent pancreatoduodenectomy or distal pancreatectomy were analyzed. Postoperative acute pancreatitis was defined as an increase in serum amylase activity greater than the upper normal limit on postoperative day 1, according to Connor’s definition of postoperative acute pancreatitis.ResultsPostoperative acute pancreatitis occurred in 63.4% of 153 of the patients undergoing pancreatoduodenectomy and 65.7% of the 166 undergoing distal pancreatectomies. Patients who developed postoperative acute pancreatitis after pancreatoduodenectomy experienced an increase in the rate of morbidity (22.7% vs 7.1%; P = .0137), including postoperative pancreatic fistula (18.6% vs 1.8%; P = .024), resulting in greater postoperative stays (21 days vs 17 days; P = .0008). Postoperative acute pancreatitis in association with an increased serum C-reactive protein ≥18.0 mg/dL (which we defined as a clinically relevant postoperative acute pancreatitis) more strongly indicated the occurrence of severe complications (P = .0032) and was an independent predictor of postoperative pancreatic fistula after pancreatoduodenectomy (odds ratio, 3.03; P = .0448). Patients who developed postoperative acute pancreatitis after distal pancreatectomy experienced similar postoperative courses regarding morbidity and the duration of postoperative stay.ConclusionThe clinical relevance of postoperative acute pancreatitis differs after a pancreatoduodenectomy versus a distal pancreatectomy. The development of effective strategies for preventing postoperative acute pancreatitis might improve surgical outcomes after pancreatoduodenectomy.     

Is tricuspid valve replacement a catastrophic operation?

Objective: Tricuspid valve replacement (TVR) has a high postoperative mortality, despite recent advances in perioperative care. We report the results of our experience in TVR with an emphasis on early mortality and morbidity and long-term follow-up. Methods: Between October 1994 and August 2007, 80 consecutive TVRs were performed in 78 patients. The mean age was 48 ± 14 (range: 20–70) years. The underlying disease of the patients was classified as rheumatic (n = 54), congenital (n = 12), endocarditis (n = 10) or degenerative (n = 4). Previous cardiac surgery had been performed in 40 patients (50%). Isolated TVR was performed in 24 patients (30%). Results: Hospital mortality occurred in one patient (1.4%). Postoperative morbidities included intra-aortic balloon pump (n = 5), bleeding re-operation (n = 4), delayed sternal closure (n = 3), acute renal failure (n = 3), subdural haematoma (n = 3), extracorporeal membrane oxygenation (n = 1), mediastinitis (n = 1) and pacemaker insertion (n = 4). In 42 patients, ventilator support was needed for more than 72 h. Based on multivariate analysis, age (p < 0.001) and the cardiopulmonary time (p = 0.004) were the identified risk factors. Follow-up was completed in all patients with a mean duration of 56 ± 37 (range: 0–158) months. During the follow-up period, there were seven deaths (8.8%), including five cardiac deaths. The 5- and 8-year survival rates were 95 ± 3% and 79 ± 9% and event-free survival rates were 76 ± 6% and 61 ± 9%, respectively. Based on multivariate analysis, the only identified predictors of late deaths was a postoperative low cardiac output (p = 0.024). Conclusions: TVR can be performed and low operative mortality can be achieved thorough optimal perioperative management in the current era.     

Safety and oncological benefits of hepatectomy for hepatocellular carcinoma in octogenarians

BackgroundThe number of octogenarians requiring surgery for hepatocellular carcinoma (HCC) is increasing. However, the safety of hepatectomy in octogenarians remains controversial. The aim of this retrospective study was to determine the effect of age on the short- and long-term outcomes of hepatectomy for HCC to evaluate the safety of hepatectomy for octogenarians.MethodsData from a total of 845 patients who underwent initial hepatectomy for HCC between April 1990 and March 2021 were retrospectively reviewed. Patients were categorized based on the age at the time of surgery (<80 years, n = 790; ≥80 years, n = 55), and the short- and long-term postoperative outcomes of the two groups were compared to evaluate whether hepatectomy is appropriate for octogenarian patients.ResultsThe proportion of octogenarian patients undergoing hepatectomy increased from 2.6% in 1990–1995 to 16.8% in 2016–2020 (P < 0.001), and the overall incidences of anatomical and major hepatectomy have increased. There was no significant difference in the morbidity rate between the octogenarians and the group of patients <80 years old (60.0% vs. 54.4%, P = 0.420), and the 90-day mortality rate was 0% in the octogenarian group. Furthermore, the two groups had similar overall survival and recurrence-free survival rates (P = 0.173 and 0.671, respectively).ConclusionFavorable postoperative outcomes following initial hepatectomy for HCC are achieved in appropriately selected octogenarians.     

Long-term surgical outcomes in patients with hepatocellular carcinoma undergoing laparoscopic vs. open liver resection: A retrospective and propensity score-matched study

Background/objectivesThere is limited availability of well-designed comparative studies using propensity score matching with a sufficient sample size to compare laparoscopic liver resection (LLR) vs. open liver resection (OLR) for hepatocellular carcinoma (HCC). We aimed to compare the feasibility and safety of LLR and OLR in patients with HCC.MethodsWe enrolled 168 patients who underwent elective LLR (n = 58) or OLR (n = 110) for HCC in two tertiary medical centers between November 2009 and December 2018. Patients who underwent LLR were propensity score-matched to patients who underwent OLR in a 1:1 ratio. Perioperative and postoperative outcomes and disease-free and overall survival rates were prospectively evaluated.ResultsAmong the 116 patients analyzed, 58 each belonged to the LLR and OLR groups. We performed 85 segmentectomies or sectionectomies, 19 left-lateral-sectionectomies, 9 left-hemihepatectomies, and 3 right-hemihepatectomies. There was no significant difference in age, sex, Child-Pugh class, original liver disease, preoperative alpha-fetoprotein, tumor size, tumor location, overall morbidity, and operative time. There was a significant difference in the length of postoperative hospital stay between the two groups (LLR vs OLR; 8 vs 10 days, p = 0.003). The 1-, 3-, and 5-year overall survival rates in the LLR and OLR groups were 96.6%, 92.8%, and 73.3% and 93.1%, 88.8%, and 76.1%, respectively (p = 0.642). The 1-, 3-, and 5-year disease-free survival rates in the LLR and OLR groups were 84.4%, 64.0%, and 60.2% and 93.1%, 67.4%, and 63.9%, respectively (p = 0.391).ConclusionLLR for HCC can be performed safely with acceptable short-term and long-term outcomes compared with OLR.     

Distal pancreatectomy with celiac artery resection acquires satisfactory survival for locally advanced pancreatic neck/body cancer

Backgrounds As a curative surgical procedure for pancreatic neck-body cancer with invasion to celiac artery (CA), the security and efficacy of distal pancreatectomy (DP) with en bloc resection of the celiac artery (DP-CAR) remain controversial. The purpose of this study was to identify the postoperative outcomes of DP-CAR.MethodsA retrospectively analysis between January 2010 and January2019 was performed in a single center. 21 patients who underwent DP-CAR and 71 patients who underwent traditional DP for pancreatic neck-body cancer were included. Postoperative morbidity, mortality, overall survival (OS) and disease-free survival (DFS) were evaluated.ResultsThere were no significant differences in major complications and mortality between two groups. The patients in DP-CAR group had more T4 tumor (61.9 vs 7.0%, P < 0.001). DP-CAR group had similar R0 resection compared with DP group (71.4% vs 87.3%, P = 0.090). The patients in DP-CAR group suffered more gastric ulcer, DGE and elevated levels of postoperative hepatic enzymes. OS (27.4 vs 32.6 months) and DFS (14.9 vs 19.5 months) between DP-CAR and DP groups were comparative (P = 0.305; P = 0.065).ConclusionsFor the patients who had pancreatic neck-body cancer with invasion to CA, DP-CAR is safety and could achieve satisfactory R0 resection, OS, and DFS.
