RESUMEN
BACKGROUND: This study: (i) assessed compliance with a consensus set of quality indicators (QIs) in pancreatic cancer (PC); and (ii) evaluated the association between compliance with these QIs and survival. METHODS: Four years of data were collected for patients diagnosed with PC. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). A multivariable analysis tested the relationship between significant patient and hospital characteristics, patient cluster effects within hospitals and survival. RESULTS: 1061 patients were eligible for this study. Significant association with improved survival were: (i) in the potentially resectable group having adjuvant chemotherapy administered following surgery or a reason documented (HR, 0.29; 95 CI, 0.19-0.46); (ii) in the locally advanced group included having chemotherapy ± chemoradiation, or a reason documented for not undergoing treatment (HR, 0.38; 95 CI, 0.25-0.58); and (iii) in the metastatic disease group included having documented performance status at presentation (HR, 0.65; 95 CI, 0.47-0.89), being seen by an oncologist in the absence of treatment (HR, 0.48; 95 CI, 0.31-0.77), and disease management discussed at a multidisciplinary team meeting (HR, 0.79; 95 CI, 0.64-0.96). CONCLUSION: Capture of a concise data set has enabled quality of care to be assessed.

BACKGROUND: Central hepatectomy (CH) is more difficult than extended hepatectomy (EH) and is associated with greater morbidity. In this modern era of liver management with aims to prevent post-hepatectomy liver failure (PHLF), there is a need to assess outcomes of CH as a parenchyma-sparing procedure for centrally located liver tumors. METHODS: A total of 178 major liver resections performed by specialist surgeons from two Australian tertiary institutions between June 2009 and March 2017 were reviewed. Eleven patients had CH and 24 had EH over this study period. Indications and perioperative outcomes were compared between the groups. RESULTS: The main indication for performing CH was colorectal liver metastases. There was no perioperative mortality in the CH group and four (16.7%) in the EH group (Pâ¯=â¯0.285). No group differences were found in median operative time [CH vs. EH: 450â¯min (290-840) vs. 523â¯min (310-860), Pâ¯=â¯0.328], intraoperative blood loss [850â¯mL (400-1500) vs. 650â¯mL (100-2000), Pâ¯=â¯0.746] or patients requiring intraoperative blood transfusion [1 (9.1%) vs. 7 (30.4%), Pâ¯=â¯0.227]. There was a trend towards fewer hepatectomy-specific complications in the CH group [3 (27.3%) vs. 13 (54.2%), Pâ¯=â¯0.167], including PHLF (CH vs. EH: 0â¯vs. 29.2%, Pâ¯=â¯0.072). Median length of stay was similar between groups [CH vs. EH: 9 days (5-23) vs. 12 days (4-85), Pâ¯=â¯0.244]. CONCLUSIONS: CH has equivalent postoperative outcomes to EH. There is a trend towards fewer hepatectomy-specific complications, including PHLF. In appropriate patients, CH may be considered as a safe parenchyma-sparing alternative to EH.

CONTEXT: Factors affecting length of hospital stay after uncomplicated pancreaticoduodenectomy have not been reported. We hypothesized that patients undergoing uncomplicated pancreaticoduodenectomy treated by fast track recovery program would have a shorter length of hospital stay compared to those managed by a standard program. METHODS: Patients without surgical or medical complications following pancreaticoduodenectomy managed by fast track or standard protocols, between 2005 and 2011, were identified and prognostic predictors for length of hospital stay determined. RESULTS: Forty-one patients treated by pancreaticoduodenectomy had no medical or surgical complications during this period. Of these patients, 20 underwent fast track recovery program compared to 21 who underwent standard care. Patients in the standard group were more likely to have a feeding jejunostomy tube (P<0.001), pylorus preserving procedure (P=0.001) and a nasogastric tube in place longer than 24 hours postoperatively (P<0.001). The median postoperative length of stay was shorter in the fast track recovery program group (8 days, range: 7-16 days) versus 14 days, range: 8-29 days; P<0.001). There were three readmissions in the fast track recovery program related to abdominal pain and none in the standard group. The overall length of stay, accounting for readmissions, still remained significantly shorter in the fast track recovery program group (median 9 days, range: 7-17 days versus median14 days, range: 8-29 days ; P<0.001). There were no significant differences in discharge destination between groups. On multivariate analysis, the only factor independently associated with postoperative discharge by day 8 was fast track recovery program (OR: 37.1, 95% CI: 4.08-338; P<0.001). CONCLUSION: Fast track recovery program achieved significantly shorter length of stay following uncomplicated pancreaticoduodenectomy.

BACKGROUNDS: This study aims to identify the objective findings of haemoglobin (Hb) drift in patients that had a Whipple's procedure in the last 10 years, their transfusion status intraoperatively and post-operatively, the potential factors affecting Hb drift, and the outcomes following Hb drift. METHODS: A retrospective study was conducted at Northern Health, Melbourne. All adult patients who were admitted for a Whipple's procedure from 2010 to 2020 were included and information collected retrospectively for demographics, pre-operative, operative and post-operative details. RESULTS: A total of 103 patients were identified. The median Hb drift calculated from a Hb level at the end of operation was 27.0 g/L (IQR 18.0-34.0), and 21.4% of patients received a packed red blood cell (PRBC) transfusion during the post-operative period. Patients received a large amount of intraoperative fluid with a median of 4500 mL (IQR 3400-5600). Hb drift was statistically associated with intraoperative and post-operative fluid infusion leading to concurrent issues with electrolyte imbalance and diuresis. CONCLUSION: Hb drift is a phenomenon that does happen in major operations such as a Whipple's procedure, likely secondary to fluid over-resuscitation. Considering the risk of fluid overload and blood transfusion, Hb drift in the setting of fluid over-resuscitation needs to be kept in mind prior to blood transfusion to avoid unnecessary complications and wasting of other precious resources.

There is multiple evidence to suggest that isolation techniques of high output enteroatmospheric fistulas (EAF) in open abdomens can be advantageous in controlling fistula effluent while allowing time for abdominal wall to granulate. The large loss of proteins, electrolytes and fluid, and the distressing nature of the open abdomen for both patients and doctors, make managing these EAFs a clinical challenge. We present our experience with a high output mucosal protruding EAF and the creation of a 'VAC donut' allowing a successful diversion of the enteric content whilst promoting granulation of the tissue bed.

CONTEXT: Delayed gastric emptying is a major cause of morbidity following pancreaticoduodenectomy. OBJECTIVE: The impact of a Braun enteroenterostomy on delayed gastric emptying, used in reconstruction following classic pancreaticoduodenectomy, was assessed. PATIENTS: Forty-four consecutive patients undergoing non-pylorus preserving pancreaticoduodenectomy from 2009 to 2011 by a single surgeon were included in this study. INTERVENTIONS: The first 20 patients had a standard antecolic gastroenterostomy and the subsequent 24 had the addition of a Braun enteroenterostomy. RESULTS: Patient characteristics, the extent of surgery, surgical findings and tumor characteristics were similar between the two groups. The delayed gastric emptying rate in the Braun enteroenterostomy (1/24, 4.2%) was significantly lower (P=0.008) than the standard reconstruction group (7/20, 35.0%). In the standard group, 6 of 7 cases (85.7%) of delayed gastric emptying were class C in nature. After exclusion of 8 total pancreatectomy patients, the pancreatic fistula rate in the Braun enteroenterostomy group (4/19, 21.1%) was similar (0.706) to the standard reconstruction group (5/17, 29.4%) as was the median length of hospital stay (10 days vs. 15 days; P=0.291). Braun enteroenterostomy technique was the only significant independent factor associated with reduced delayed gastric emptying with an odds ratio of 0.08 (95% confidence interval: 0.01-0.73; P=0.025). CONCLUSION: The use of Braun enteroenterostomy following non-pylorus preserving pancreaticoduodenectomy appears to result in a significant reduction in delayed gastric emptying.

BACKGROUND: Single-stage approach with bile duct exploration is considered the most efficient and cost-effective method of bile duct clearance. In Australia, apart from centres with subspecialty interests, notably in Brisbane, Queensland, a multi-stage approach with endoscopic retrograde cholangiopancreatography (ERCP) is used more frequently. We aim to evaluate the impact of single stage laparoscopic trans-cystic exploration (LTCE) versus multi-stage approach for choledocholithiasis. METHODS: This was a retrospective cohort study. Medicare Benefits Schedule codings were used to identify patients who had the following procedures between December 2011 and December 2019: laparoscopic cholecystectomy (LC) and ERCP, LC and LTCE, LC and LTCE and ERCP. Primary outcomes were number of hospital procedures, admissions and additive length of stay (aLOS), the cumulative hospital stay from admission to discharge. RESULTS: Of 607 patients, 204 (34%) patients received a single-stage LTCE, while 403 (66%) patients had a multi-stage approach. In the LTCE group, 82% (168) patients and 93% (190) patients had one procedure and one admission respectively for stone clearance (P = 0.001). The median aLOS was 4 days for LTCE versus 7 days for multi-stage approach (P = 0.001; 95% CI for difference - 3 to -2). In the multi-stage group, 16% (65) patients had three or more procedures and 49% (199) patients required two or more hospital admissions to achieve stone clearance. CONCLUSION: LTCE for stone clearance can be successfully accomplished with reductions in hospital admissions, number of procedures and length of stay. This has further economic and health resource implications.

Background: Common bile duct exploration (CBDE) is performed uncommonly. Issues surrounding its uptake in the laparoscopic era include perceived difficulty and lack of training. We aim to determine the success of CBDE performed by "specialist" and "nonspecialist" common bile duct (CBD) surgeons to determine whether there is a substantial difference in success and safety. Methods: A 10-year retrospective audit was performed of patients undergoing CBD exploration for choledocholithiasis. Northern Health maintains an on-call available "specialist" CBD surgeon roster to aid with CBDE. Results: Five hundred fifty-one patients were identified, of which 489/551 (88.7%) patients had stones successfully cleared. Specialists had a higher success rate (90.8% versus 82.6%, P = .008), associated with a longer surgical time. Method (transcystic or transductal), approach (laparoscopic or open), and indication for operation were similar between groups. There was no significant difference in complications. To be confident of a surgeon having an 80% success rate, 70 procedures over 10 years were required, however, an "in-control" 50% success rate may only require 1 procedure per year. Conclusion: While specialist CBDE surgeons have improved success rates, nonspecialist general surgeons also have a good and comparable success rate with an equivalent complication rate. With realistic annual targets, nonspecialist CBD surgeons should be encouraged to perform CBDE in centers without specialist support.

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) presents as unresectable disease in 80% of patients. Limited Australian data exists regarding management and outcome of palliative management for PDAC. This study aims to: (i) identify patients with PDAC being managed with palliative intent; (ii) assess the type of palliative management being used. METHODS: A prospectively maintained pancreatic database at Western Health (2015-2017) was used to identify patient demographics; stage and multidisciplinary decision regarding resectability and operative interventions; palliative care; use of chemotherapy, radiotherapy and; management of exocrine and endocrine insufficiency. Data on chemotherapy use, number of hospital admissions, emergency department attendances and intensive care unit admissions 30 days prior to death were recorded. RESULTS: One-hundred and eleven patients had diagnosis of PDAC, 15% with locally advanced and 45% with metastatic PDAC. Among the locally advanced and metastatic PDAC, 48% received biliary stent insertions, 93% had palliative care referral, 45% received palliative chemotherapy and 10% received radiotherapy. Dietitian referral occurred in 79% and 36% were prescribed with a pancreatic enzyme replacement therapy. Diabetes mellitus was present in 52% of which 31% was new onset. Within 30 days prior to death, 11% patients received palliative chemotherapy, 32% were hospitalized and 11% visited an emergency department more than once. Sixty-five percent died in hospital. CONCLUSION: A high proportion of patients diagnosed with locally advanced and metastatic PDAC received palliative care referrals and appropriate level of end-of-life care. Further prospective studies are necessary, examining the management and impacts of pancreatic insufficiency in this group.

BACKGROUND: Laparoscopic common bile duct exploration (LCBDE) can be performed to treat choledocholithiasis at the time of laparoscopic cholecystectomy. The aim of this study was to identify factors that predict the success of LCBDE. MATERIALS AND METHODS: A retrospective audit was performed on patients who underwent LCBDE for the management of choledocholithiasis at Northern Health between 2008 and 2018. RESULTS: A total of 513 patients were identified with an overall success rate of 90.8%. Most LCBDE were done through a transcystic approach with the remainder through a choledochotomy. When comparing patients with a successful operation to those that were unsuccessful, univariate analysis demonstrated significant differences in preoperative white cell count and number of duct stones found. Age and elevated nonbilirubin liver function tests were found to be significant factors associated with the failure of LCBDE on multivariate analysis. The likelihood of a failed operation in those with multiple stones was observed to be almost halved compared with patients with single stone although this did not reach significance [odds ratio (OR): 0.53, 95% confidence interval (CI): 0.28-1.01, P=0.055]. Multivariate analysis indicated that unsuccessful procedures (OR: 10.13, 95% CI: 4.34-23.65, P<0.001) and multiple duct stones (OR: 3.79, 95% CI: 1.66-8.67, P=0.002) were associated with an increased risk of severe complications. CONCLUSIONS: A single impacted stone may be more difficult to remove, however complications were more likely to be associated with multiple duct stones. With no other clinically relevant predictive factors, and because of the high success of the procedure and the low morbidity, LCBDE remains an option for all patients with choledocholithiasis.

BACKGROUND: Splenectomy is a surgical procedure indicated in a variety of medical conditions including trauma. Post-operatively, there is a lifelong risk of developing overwhelming sepsis from encapsulated bacteria, most commonly due to Streptococcus pneumoniae. Splenic autotransplantation has been proposed as a method to recover splenic function in patients requiring splenectomy with otherwise normal spleens. This study aims to systematically review the literature to determine the efficacy of spleen autotransplantation. METHODS: MEDLINE, PubMed and the Cochrane Library were searched for all studies assessing splenic autotransplantation (January 1947 to July 2018). Data were extracted on study characteristics, outcomes assessed, including spleen scintigraphy results, blood film counts and serum immunoglobulin (Ig) levels. RESULTS: Data were obtained from 18 primary studies. All studies demonstrated return of regenerated spleen tissue in the majority of their patients (95.3%) on spleen scintigraphy. In 12 studies, 90.2% of patients had blood films return to normal following transplantation. Ig levels were shown to return to normal in all 12 studies where it was assessed. In 11 studies, 3.7% of patients had post-operative complications. In five studies, 1.3% of patients had post-operative infections in the follow-up period. CONCLUSION: Splenic autotransplantation is a safe procedure with minimal complications that can return splenic filtration function and Ig levels to normal ranges. It has not been confirmed whether autotransplantation provides meaningful protection against overwhelming post-splenectomy infections.

Gallbladder agenesis is a rare but well-documented anatomical variation. Pre-operative diagnosis may be difficult as patients can present with typical symptoms of biliary colic and imaging may be misleading. We report a case of choledochoscopy and common bile duct stone retrieval in a patient found to have agenesis of the gallbladder intra-operatively.
RESUMEN
BACKGROUND: Pancreaticoduodenectomy (PD) is associated with high morbidity, which is perceived to be increased in the elderly. To our knowledge there have been no Australian series that have compared outcomes of patients over the age of 80 undergoing PD to those who are younger. METHODS: Patients who underwent PD between January 2008 and November 2015 were identified from a prospectively maintained database. RESULTS: A total of 165 patients underwent PD of whom 17 (10.3%) were aged 80 or over. The pre-operative health status, according to American Society of Anesthesiologists class was similar between the groups (P = 0.420). The 90-day mortality rates (5.9% in the elderly and 2% in the younger group; P = 0.355) and the post-operative complication rates (64.7% in the elderly versus 62.8% in the younger group; P = 0.88) were similar. Overall median length of hospital stay was also similar between the groups, but older patients were far more likely to be discharged to a rehabilitation facility than younger patients (47.1 versus 12.8%; P < 0.0001). Older patients with pancreatic adenocarcinoma (n = 10) had significantly lower median survival than the younger group (n = 69) (16.6 versus 22.5 months; P = 0.048). CONCLUSION: No significant differences were seen in the rate of complications following PD in patients aged 80 or over compared to younger patients, although there appears to be a shorter survival in the elderly patients treated for pancreatic cancer. Careful selection of elderly patients and optimal peri-operative care, rather than age should be used to determine whether surgical intervention is indicated in this patient group.

Although there is abundant evidence that gastrin-releasing peptide acts as a mitogen in various carcinoma cell lines, the effect of administration of gastrin-releasing peptide on the colorectal mucosa in vivo has not been reported. The aims of this study were to determine whether continuous infusion of gastrin-releasing peptide stimulated proliferation or accelerated carcinogenesis in the rat gastrointestinal tract and other organs. The possible requirement for C-terminal amidation for mitogenic activity in vivo was also investigated. Proliferation was measured in the colon by metaphase index and by immunostaining for the proliferation marker Ki-67, and in other tissues by immunostaining alone. Acceleration of colorectal carcinogenesis was assessed by counting aberrant crypt foci after treatment with the carcinogen azoxymethane. Defunctioning of the rectum reduced both the proliferative index and the crypt height of the rectal mucosa of untreated rats. Treatment with amidated or glycine-extended gastrin-releasing peptide for 4 weeks using implanted mini-osmotic pumps resulted in a two- to three-fold increase in proliferation, and an increase in crypt height, in the defunctioned rectal mucosa (p<0.001), with smaller but significant increases in the caecum and distal colon. No changes in proliferation were detected in lung, pancreas or gastric mucosa. The numbers of aberrant crypt foci in the mid-colon, distal colon and rectum following treatment with azoxymethane were also significantly increased by infusion with amidated or glycine-extended gastrin-releasing peptide. We conclude that administration of gastrin-releasing peptide to mature rats stimulates proliferation and accelerates carcinogenesis in the colorectal mucosa, and that C-terminal amidation is not essential for either effect. Gastrin-releasing peptides could thus potentially act as promoters of colorectal carcinogenesis.

Hepatic malignancy with regional lymph node involvement is generally associated with poor prognosis. Lymphatic drainage from the liver to extrahepatic lymph nodes follows a complex and unpredictable pathway. To add to the complexity of management of regional lymph nodes in hepatic malignancies, not all liver cancers have the same propensity to metastasize through lymphatics. Lymphadenectomy has had mixed results in terms of improving patient survival. Other therapies especially anti-lymphogenic agents might play a role in the near future.

BACKGROUND: Partial splenectomy is preferred to total splenectomy when possible to reduce the risk of life-threatening infection. Several techniques have been described, each with its merits. Laparoscopic transection with monopolar saline-cooled radiofrequency coagulation has not been previously described. PATIENTS AND METHODS: Two patients with enlarging cystic splenic lesions consented to laparoscopic partial splenectomy. In 1 case, high-power saline-cooled monopolar radiofrequency transection was performed with a laparoscopic sealing hook; the procedure was performed with a rigid resectoscope and ball diathermy in the other. RESULTS: Both cases were performed without complications. Transection with the resectoscope and ball diathermy was combined with selective clamping of the splenic hilar vessels and was performed in 100 minutes with estimated blood loss of 250 mL. Transection with the sealing hook was performed in 80 minutes without hilar vessel clamping, with an estimated blood loss of 100 mL. No additional hemostatic agents were required for either case. CONCLUSIONS: Laparoscopic partial splenectomy can be performed with monopolar saline-cooled radiofrequency for parenchymal transection and hemostasis in a simple and effective manner.
