RESUMEN
PURPOSE: Type III endoleak can be difficult to distinguish from Type I endoleak. Depending on the stent graft anatomy, the use of standard bifurcated endografts may not be technically feasible, and patients may have to be subject to an aorto-uni-iliac repair with femoral-femoral bypass or open surgery. CASE REPORT: We report a case of an 86-year-old male who had a Type IIIb endoleak 20 years post EVAR which was characterized on angiography to be from a hole close to the bifurcation limb origin. The initial Talent (Medtronic, Santa Rosa, California) device had a 50 mm main body common trunk, which was not amenable to treatment with standard devices. He was successfully treated with a custom-made device with an inverted contralateral limb. CONCLUSIONS: Our case highlights the need for lifelong surveillance post EVAR as endoleak may present decades post initial EVAR. It also demonstrates that many Type III endoleak which were otherwise deemed unsuitable for treatment with standard devices may potentially be treatable with custom-made device (CMD). This solution preserves a percutaneous option in a now older person which avoids surgical bypass. Further studies are required to establish the durability of this treatment and survey for recurrence.

BACKGROUND: Results from the BIOLUX P-III registry have demonstrated favourable outcomes of Passeo-18 Lux™ (Biotronik®, Buelach, Switzerland) drug-coated balloon in treating obstructive infrainguinal peripheral artery disease, but it has not been established if Asians would benefit to the same extent as non-Asians. METHODS: A subgroup analysis was performed on the 24-month data comparing the Asian cohort (AC) to non-Asian cohort (NAC). RESULTS: AC included 49 patients with 77 lesions. AC was significantly younger (65.6 vs 70.3 years, p < 0.05), had more diabetes (87.8% vs 45.3%, p < 0.05), and was more likely to present with CLTI (73.5% vs 35.3%, p < 0.001) compared to NAC. They had significantly longer mean target lesions (115 vs 86.9 mm, p = 0.006), and received significantly higher paclitaxel doses (10.7 vs 7.2 mg, p = 0.0005). Device, technical and procedural successes were 125/125(100%), 95/97(97.5%) and 45/49(91.8%), respectively. There was no significant difference in target lesion revascularization rates between groups (10.5% vs 12%, p = 0.91). However, the AC had more major adverse events (30.2% vs 16.1%, p = 0.001), amputations (26.3% vs 6.2%, p < 0.05) and mortality (37.9% vs 10.6%, p < 0.05) at 24 months. CONCLUSION: Passeo-18 Lux™ use was efficacious in Asians, but was associated with higher adverse events, amputations and mortality rates, likely attributable to poorer patient comorbidities and more extensive PAD.

PURPOSE: While endovascular repair of aortic aneurysm (EVAR) has become the mainstay treatment for abdominal aortic aneurysm (AAA), it is not without its disadvantages. Feared complications include graft infections, fistulation and endoleak, the outcomes of which may be life limiting. CASE REPORT: We present a case of a 57 year-old patient with human immunodeficiency virus (HIV) previously treated with EVAR for AAA complicated by endoleak post treatment. He developed an aorto-psoas abscess 2 years later which harboured Mycobacterium avium complex, and medical therapy was unsuccessful. He eventually underwent an extra-anatomical bypass and graft explant, for which an aortoenteric fistula was also discovered and repaired. CONCLUSION: Infection of endografts post EVAR is relatively rare, and there are presently no guidelines concerning its management. The concomittance of aorto-psoas abscess and aortoenteric fistula is even more uncommon, and necessitated surgical explant for source control purposes in our patient. Lifelong surveillance is required for complications of the aortic stump and bypass patency.

BACKGROUND: At present, the majority of outcome studies of survival of hepatocellular carcinoma (HCC) post-liver resection (post-LR) present actuarial survival data, which often results in overestimation of survival. We sought to evaluate the actual 10-year survival post-LR for HCC and identify variables that are associated with long-term survival. METHODS: We performed a retrospective review of 600 consecutive patients who underwent primary LR for HCC from 2000 to 2010 at our institution. Twenty-eight patients (4.7%) with 90-day mortality and 125 patients who were lost to follow-up within 10 years were excluded leaving 447 patients who met the study criteria. RESULTS: There were 140 actual 10-year survivors of which 57 (40.7%) had a recurrence within 10 years. The actual 10-year overall survival (OS) rate of the 447 patients was 31.5% and the actual 10-year recurrence-free survival (RFS) was 18.6%. Multivariate analyses demonstrated that only age >65 years (OR, 0.29; p < .001) (OR, 0.973; p = .041) and presence of cirrhosis (OR. 0.37; p = .005) (OR, 0.31; p = .001) were independent factors negatively associated with actual 10-year OS and actual 10-year RFS, respectively. CONCLUSION: Approximately one-third of patients will survive over 10 years after LR for HCC. Amongst these 10-year survivors, 41% had developed recurrent cancer within 10-years of follow-up.

Pancreatic pseudocyst (PP) is a known complication of pancreatitis. When a rupture occurs, patients often become haemodynamically unstable and require emergency surgery for source control. Conventionally, such a procedure is carried out through open technique due to patient, surgeon and technical factors. We present two cases of emergency laparoscopic surgery performed for ruptured PP. Our first patient was a 53-year-old male with a ruptured 17.6 cm pancreatic body pseudocyst who underwent a laparoscopic washout, adhesiolysis, necrosectomy, distal pancreatectosplenectomy and cholecystectomy. The second patient was a 66-year-old male with a ruptured 11 cm pancreatic body pseudocyst who underwent laparoscopic surgery, subsequently converted to hand-assisted surgery. We compare our cases with the existing literature and discuss pertinent management considerations. In conclusion, we demonstrated that emergency laparoscopic adhesiolysis, necrosectomy and distal pancreatosplenectomy are feasible and safe for the management of ruptured pseudocyst when performed by an experienced surgeon. However, further studies are needed to determine the advantages or limitations of the minimally invasive surgical approach for the management of these complicated cases.
RESUMEN
Ischaemic diabetic heel ulcers are difficult to treat and prognosis is often guarded. The aim was to document our outcome of treating heel ulcers following revascularization in a predominantly diabetic Asian cohort presenting with chronic limb threatening ischaemia from Singapore. Retrospective cohort study (n = 66, 66 limbs) over a 5-year period. Data were collected from hospital electronic health records. Outcomes included time to healing, amputation free survival (AFS), and mortality. Minimum follow-up period was 6 months. Multivariate regression analysis was performed to look for factors associated with poor outcome. Mean age was 67.4 ± 8.8 years. 62/66 (93.9%) were diabetics. Mean wound size at presentation was 3.6 ± 2.3 cm. Mean Wound, Ischaemia, Foot Infection (WIFI) score was 5 ± 1.6. 12/66 (18%) patients had a patent posterior tibial artery pre-operatively. Straight line flow was restored in only 31/66 (46.9) patients but 47/66 (71.2%) had successful limb salvage. Median time to wound healing was 90.0 (IQR 60-180) days. A median of 1 (IQR 0-2) wound debridement was required. Patients who underwent negative pressure dressing (23/66; 34.8%) required a median of 26 (IQR 13-33) cycles to achieve healing. Amputation free survival (AFS) was 72% and 68% at 6- and 12-months, respectively. Mortality rate was 16.7% and 19.7% at 6- and 12-months, respectively. Low albumin level and initial Rutherford class were independent predictors of worse 6-month AFS. Outcomes of heel ulcers post revascularisation may not be as poor as previously described. Persistent attention to wound care with multidisciplinary effort is needed for optimal healing.

BACKGROUND: Pure laparoscopic donor hepatectomy (L-DH) has seen a rise in uptake in recent years following the popularization of minimally invasive modality for major hepatobiliary surgery. Our study aimed to determine the safety and compare the perioperative outcomes of L-DH with open donor hepatectomy (O-DH) and laparoscopic non donor hepatectomy (L-NDH) based on our single institution experience. METHODS: Eighty of 113 laparoscopic hemi-hepatectomies performed between 2015 and 2022 met study inclusion criteria. Of these, 11 were L-DH. PSM in a 1:2 ratio of L-DH versus L-NDH and 1:1 ratio of L-DH versus O-DH were performed, identifying patients with similar baseline clinicopathological characteristics. RESULTS: After 2:1 matching, the L-DH cohort were significantly younger (P < 0.001) and had lower ASA scores (P < 0.001) than the L-NDH cohort. L-DH was associated with a longer median operating time (P < 0.001) and shorter median postoperative stay (P < 0.001) than L-NDH. After 1:1 matching, there were no significant differences in baseline demographic between the L-DH and O-DH cohorts. L-DH was associated with lower median blood loss (P = 0.040) and shorter length of stay compared to O-DH (P = 0.004). There were no significant differences in recipient outcomes for both cohorts. CONCLUSION: L-DH can be adopted safely by surgeons experienced in L-NDH and ODH. It is associated with decreased blood loss and shorter length of stay compared to O-DH.

Spontaneous aortic thrombosis is exceedingly rare, and optimal treatment remains uncertain. We present an unusual case of a spontaneous aortic thrombus at the renal artery level in a patient undergoing active cisplatin treatment for urothelial carcinoma. Management included catheter-directed thrombolysis followed by thrombectomy. An open cutdown was performed on the left common femoral artery (CFA), with right groin access via a 6-Fr sheath. Clamping of the left superficial and deep femoral arteries, along with balloon occlusion of the right common iliac artery, prevented distal embolization. A Coda balloon introduced via direct left CFA puncture with a 20-Fr sheath was positioned above the aortic thrombus. After inflation, clots were trawled to the sheath, "sandwiching" the clots before removal of the balloon and sheath via the left groin. Post-operatively, the patient recovered well and received continued therapeutic anticoagulation.
RESUMEN
INTRODUCTION: The ability to stratify the difficulty of minimally invasive liver resection (MILR) allows surgeons at different phases of the learning curve to tackle cases of appropriate difficulty safely. Several difficulty scoring systems (DSS) have been formulated which attempt to accurately stratify this difficulty. The present study aims to review the literature pertaining to the existing DSS for MILR. METHODS: We performed a systematic review and metanalysis of the literature reporting on the formulation, supporting data, and comparison of DSS for MILR. RESULTS: A total of 11 studies were identified which reported on the formulation of unique DSS for MILR. Five of these (Ban, Iwate, Hasegawa, Institut Mutaliste Montsouris [IMM], and Southampton DSS) were externally validated and shown to predict difficulty of MILR via a range of outcome measures. The Ban DSS was supported by pooled data from 10 studies (9 LLR, 1 RLR), Iwate by 10 studies (8 LLR, 2 RLR), Hasegawa by four studies (all LLR), IMM by eight studies (all LLR), and Southampton by five studies (all LLR). There was no clear superior DSS. CONCLUSION: The existing DSS were all effective in predicting difficulty of MILR. Present studies comparing between DSS have not established a clear superior system, and the five main DSS have been found to be predictive of difficulty in LLR and two of these in RLR.

BACKGROUND: Liver transplantation remains the optimal treatment for multifocal hepatocellular carcinoma (HCC). However, due to resource constrains, other therapeutic modalities such as liver resection (LR), are frequently utilized. LR, however, has to be balanced against potential morbidity and mortality along with the risks of early recurrence leading to futile surgery. In this study, we evaluated preoperative factors, including inflammatory indices, in predicting early (< 1 year) recurrence in patients who underwent LR for multifocal HCC. METHODS: This was a post hoc analysis of 250 consecutive patients with multifocal HCC who underwent LR. RESULTS: After exclusion of 10 patients with 30-day/in-hospital mortality, 240 were included of which 134 (55.8%) developed early recurrence. Hepatitis B/C aetiology, 3/ > more hepatic nodules and elevated alpha-fetoprotein (AFP) ≥ 200 ng/ml were significant independent preoperative predictors of early recurrence. The early recurrence rate was 72.1% when 2 out of 3 significant predictive factors were present. The conglomerate of all 3 factors predicted early recurrence of 100% with a statistically significant association between number of predictive factors and early recurrence (p < 0.001). CONCLUSION: Better patient selection via the use of preoperative predictive factors of early recurrence such as hepatitis B/C aetiology, ≥ 3 nodules and elevated AFP ≥ 200 ng/ml may assist in identifying patients in whom LR is deemed futile and improve resource allocation.

Primary breast carcinomas often present as ill-defined, infiltrative lesions which may contain calcifications, whereas metastatic cancers from non-mammary sites are often more well-circumscribed, sharply demarcated from the adjacent breast tissue and are usually not associated with calcifications, although there are exceptions. We report an atypical case of a lady with lung adenocarcinoma with pleural involvement, who presented with diffuse breast swelling with calcifications on imaging from metastatic lung adenocarcinoma, the first of its kind in the literature. We postulate that the pathophysiology of this was due to lymphatic spread of the tumour from the pleura resulting in retrograde lymphovascular congestion of the breast, resulting in swelling and dystrophic calcification.

OBJECTIVE: The aim of this study was to evaluate the efficacy of acellular dermal matrix (ADM) use in reducing Frey syndrome (FS) rates in patients postparotidectomy. STUDY DESIGN: We performed a systematic review and meta-analysis of existing literature comparing rates of FS with and without ADM use. RESULTS: Eight studies were shortlisted for qualitative study, of which 7 compared rates of FS with and without the use of ADM. A total of 211 patients underwent parotidectomy with the use of ADM. Of these, mean patient age was 44.7 (SD ± 7.2); 89 of 159 were pleomorphic adenoma (55.9%), 29 of 159 with histological diagoses stated were Warthin's tumor (18.2%), and 159 of 211 were other histologic diagnoses (25.7%). Subjective and objective incidence rates for FS were 23 of 211 (10.9%) and 7 of 211 (3.3%), respectively. Patients in whom ADM barriers were used had significantly lower rates of subjective and objective FS (relative risk = 0.22; 95% confidence interval, 0.09-0.57; P = .002; and relative risk = 0.07; 95% confidence interval, 0.07-0.33; P < .001), respectively, compared to patients with no ADM. CONCLUSION: The use of ADM was associated with lower FS rates compared to no ADM and should be considered in routine use to prevent this condition.

BACKGROUND: Despite the wide use of laparoscopy for liver resection, laparoscopic caudate lobe resections(L-CLR) remain technically challenging, only attempted by experts in the field. The primary objective of this study was to determine the safety and compare the perioperative outcomes of L-CLR with O-CLR based on our single institution experience in a 1:2 propensity score-matched controlled study based on our single institution experience. METHODS: Between 2004 and 2020, 67 consecutive patients who underwent CLR at Singapore General Hospital were identified. Propensity score matching (PSM) of laparoscopic versus open caudate lobe resections(O-CLR) was performed in a 1:2 ratio with no replacements using nearest neighbour matching method. RESULTS: L-CLR was associated with a significantly decreased median blood loss (150 mL versus 500 mL, P = 0.001) and a decreased median post-operative stay (3 days versus 7.5 days, P = <0.01) in the unmatched cohorts. After 1:2 propensity score matching, these results were again demonstrated with a significantly lower blood loss (150 mL versus 400 mL, P = 0.016) and a shorter postoperative stay (3 days versus 7 days, P = <0.01) in favour of L-CLR. 30-day readmission and major morbidity (Clavien-Dindo grade > 2) rates were all in favour of L-CLR as well but could not reach statistical significance. CONCLUSION: L-CLR can be safely performed by experienced surgeons. It is associated with decreased blood loss and shorter perioperative stay compared to O-CLR.

BACKGROUND: The majority of evidence with regards to minimally invasive liver resection (MILR) favors its application in minor hepatectomies. We conducted a propensity score-matched (PSM) analysis to determine its feasibility and safety in major hepatectomies (MIMH) for liver malignancies. METHODS: Retrospective review of 130 patients who underwent MIMH and 490 patients who underwent open major hepatectomy (OMH) for malignant pathologies was performed. PSM in a 1:1 ratio identified two groups of patients with similar baseline clinicopathological characteristics. Perioperative outcomes were then compared. Major hepatectomies included traditional major (>3 segments) and technical major hepatectomies (right anterior and right posterior sectionectomies). RESULTS: Both cohorts were well-matched for baseline characteristics after PSM. Of 130 MIMH cases, there were 12 conversions to open. Comparison of perioperative outcomes demonstrated a significant association of MIMH with longer operation time and more frequent application of Pringle's maneuver (PM), but decreased postoperative stay. These results were consistent on a subgroup analysis that only included patients undergoing traditional major hepatectomies. A second subgroup analysis restricted to cirrhotic patients demonstrated that while perioperative outcomes were equivalent, MIMH was similarly associated with a longer operative time. Subset analyses of resections performed after 2015 demonstrated that MIMH was additionally associated with a lower postoperative morbidity compared to OMH. CONCLUSION: Comparison of perioperative and short-term oncological outcomes between MIMH and OMH for malignancies demonstrated that MIMH is feasible and safe. It is associated with a shorter hospital stay at the expense of a longer operation time compared to OMH.

Ampullary neoplasms are relatively uncommon lesions with a risk of progression to malignancy. Depending on its nature, size and location, it may be best treated with endoscopic papillotomy, pancreaticoduodenectomy or transduodenal ampullectomy. Transduodenal ampullectomy offers a higher chance of complete resection compared to endoscopic papillotomy, and carries lower morbidity than a pancreaticoduodenectomy, making it the ideal choice for localised ampullary tumour not involving the ducts but not amenable to complete endoscopic resection. While traditionally performed via open surgery, it has been attempted via laparoscopic approach and more recently robotic approach. We present a case of a 63-year-old man who underwent a robotic transduodenal ampullectomy for ampullary adenoma with high grade dysplasia, and review the literature surrounding robotic transduodenal ampullectomy.
RESUMEN
BACKGROUND: The utility of minimally-invasive liver resection (MILR) for deep centrally located tumours (CLT) remains controversial. We aimed to review our institution's experience and outcomes with minimally invasive central hepatectomy (CH) and right anterior sectionectomy (RAS) for CLT in a propensity score-matched (PSM) analysis. METHODS: Retrospective review of a prospectively maintained surgical database revealed 23 patients who underwent MILR (6 CH, 17 RAS) and 53 patients who underwent open liver resection (OLR; 24 CH, 29 RAS) for CLT. PSM in a 1:1 ratio identified two groups of patients with similar baseline clinicopathological characteristics. Peri-operative outcomes were then compared. RESULTS: There was one laparoscopic-assisted, one robot-assisted and two laparoscopic-converted-open procedures in the MILR cohort. Across the unmatched cohort, there was only one mortality (MILR) and five patients with major morbidity (all OLR). MILR was associated with a longer operating time (P < 0.001), but shorter post-operative hospital stay (P = 0.002) and decreased morbidity (P = 0.018) in the unmatched cohort. Examination of peri-operative outcomes after PSM revealed that MILR was similarly associated with a longer operating time (P = 0.001) and shortened post-operative hospital stay (P = 0.043). OLR was associated with a significantly reduced application of Pringle manoeuvre (P = 0.004). There were no significant differences between MILR and OLR with regards to blood loss, blood transfusions, morbidity and margin status in the PSM analysis. CONCLUSION: MILR for CLT is safe and feasible when performed by experienced surgeons. It is associated with shorter hospital stays but at the expense of longer operation times and more frequent application of Pringle manoeuver.

BACKGROUND: The management of HCC differs depending on the extent of disease. Surgery may be offered in selected cases of T4 disease as defined by AJCC 8th. However, outcome data post partial hepatectomy (PH) for T4 disease is scarce. We sought to evaluate the outcomes of patients post resection of T4 HCC and assess preoperative predictive factors of early recurrence. METHODS: We performed a retrospective review of 235 consecutive patients who underwent resection for T4 HCC from 2001 to 2018 at our institution. RESULTS: Median overall survival was 35.9 months (95% CI 25.7-46.0). 109 patients (49.5%) developed recurrence, of which 94 patients (42.7%) experienced early recurrence within 12 months. Median time to recurrence was 38.1 months. Multivariate analysis demonstrated that vascular invasion were significant independent preoperative predictor of early recurrence post resection. Patients who experienced early recurrence had a significantly shorter median overall survival 14.3 months (95% CI 25.7-46.0) compared to those who did not (55.5 months, 95% CI 40.6-70.8, p = .000). CONCLUSION: Selected patients with T4 HCC may benefit from PH. Macrovascular invasion was associated with early recurrence within 12 months.

BACKGROUND: As the COVID-19 pandemic sweeps across the world, healthcare departments must adapt to meet the challenges of service provision and staff/patient protection. Unlike elective surgery, acute care surgery (ACS) workloads cannot be artificially reduced providing a unique challenge for administrators to balance healthcare resources between the COVID-19 surge and regular patient admissions. METHODS: An enhanced ACS (eACS) model of care is described with the aim of limiting COVID-19 healthcare worker and patient cross-infection as well as providing 24/7 management of emergency general surgical (GS) and trauma patients. The eACS service comprised 5 independent teams covering a rolling 1:5 24-hr call. Attempts to completely separate eACS teams and patients from the elective side were made. The service was compared to the existing ACS service in terms of clinical and efficiency outcomes. Finally, a survey of staff attitudes towards these changes, concerns regarding COVID-19 and psychological well-being was assessed. RESULTS: There were no staff/patient COVID-19 cross-infections. Compared to the ACS service, eACS patients had reduced overall length of stay (2-days), time spent in the Emergency Room (46 min) and time from surgery to discharge (2.4-hours). The eACS model of care saved financial resources and bed-days for the organisation. The changes were well received by team-members who also felt that their safety was prioritised. CONCLUSION: In healthcare systems not overwhelmed by COVID-19, an eACS model may assist in preserving psychological well-being for healthcare staff whilst providing 24/7 care for emergency GS and trauma patients.
