Local recurrence risk factors and outcomes in minimally invasive thermal ablation for liver tumors: a single-institution analysis

BACKGROUND

Minimally Invasive thermal ablation (MITA) of liver tumors is a commonly performed procedure, alone or in combination with liver resection. Despite being a first-option strategy for small lesions, it is technically demanding, and many concerns still exist about local disease control.

METHODS

Consecutive patients undergoing MITA from 1-2019 to 12-2022 were retrospectively enrolled. Risk factors of local recurrence were investigated through univariate and multivariable cox regression analysis.

RESULTS

At the multivariable analysis of the 207 nodules undergoing MITA, RFA was associated with worse local Recurrence Free Survival (lRFS) than MWA (HR 2.87 [95 % CI 0.96-8.66], p = 0.05), as well as a concomitant surgical resection (HR 3.89 [95 % CI 1.06-9.77], p = 0.02). A concomitant surgical resection showed worse lRFS in the subgroup analysis of both HCC (HR 3.98 [95 % CI 1.16-13.62], p = 0.02) and CRLM patients (HR 2.68 [95 % CI 0.66-5.92], p = 0.04). Interestingly, a tumor size between 30 and 40 mm was not associated to worse lRFS.

CONCLUSION

MWA may reduce the risk of local recurrence in comparison to RFA, while MITA associated to liver resection may face an increased risk of local recurrence. Further prospective studies are needed to confirm such results.

Robotic 8-mm trocar fascial wounds: To close or not to close?

BACKGROUND

The aim of this study was to investigate 8-mm robotic trocar site hernia (TSH) rate over the short and long term, providing aids to manage the related fascial wounds.

METHODS

A retrospective analysis of 320 patients undergoing robotic surgery was conducted. The primary outcome was 8-mm TSH rate with a minimum follow-up of 12 months. The secondary outcome was the rate of haematomas and infections related to 8-mm wounds and their association with patient comorbidities and trocar position.

RESULTS

One case of TSH was observed (0.31%). There were 15 cases of wound infection (4.68%) and 22 cases of wound haematoma (6.87%). Trocar related complications were significantly associated with patient comorbidities, not with trocar position.

CONCLUSIONS

Our results do not justify the 8-mm fascial wound closure. Data concerning the association between trocar-related complications and patient comorbidities strengthen the need to implement the control of metabolic state and correct administration of perioperative therapy in high-risk patients.

One-stage resection of primary colorectal cancer and hepatic metastases using the Habib Device: analysis of 40 consecutive cases treated in a Unit of general surgery

BACKGROUND

More than 50% of patients with colorectal cancer (CRC) present or develop hepatic metastases (HM). The intraoperative use of the Habib 4X^® radio frequency probe device is safe in resetting HM and allows a one-stage resection of both CRC and HM with a similar mortality rate than a two-stage surgical treatment.

METHODS

After an exhaustive residential training at the reference center for hepato-biliary surgery of the Imperial College of London, we treated at our unit of general surgery 40 consecutive patients with CRC and HM with the one-stage resection, using the Habib 4X^® intraoperative radiofrequency probe device to reset HM.

RESULTS

None of the 40 patients died during the intra-operatory and post-operatory periods, none presented liver failures during the postoperative course nor complication related to the Habib's resection procedure (e.g. bleeding, abscess, bile leak). The amount of intra-operative liver bleeding was minimal. New HM arose in 10 (25%) cases, with a mean disease-free interval of 13 months, but the hepatic tissue close to previous resections remained cancer-free. The 69.7% of patients were disease-free at month 24 of the post-operative follow-up and 5-year rate was about 70%.

CONCLUSIONS

The data suggest that surgeons well trained at a reference center for hepato-biliary surgery may perform with excellent results the one-stage CRC and HM resection with the Habib 4X^® device even in a Unit of general surgery.

Outcomes of Renal Stone Surgery Performed Either as Predonation or Ex Vivo Bench Procedure in Renal Grafts from Living Donors: A Systematic Review

AIMS

We aimed to summarize available evidence about intraoperative and postoperative donors' and recipients' outcomes following stone surgery in renal grafts from living donors performed either before donation or as ex vivo bench surgery at the time of living-donor nephrectomy.

METHODS

A systematic review of PubMed, ISI Web of Knowledge, and Scopus databases was performed in September 2020. We included full papers that met the following criteria: original research, English language, human studies, and describing the results of stone surgery in renal grafts from living donors performed either before transplantation or as ex vivo bench surgery.

RESULTS

We identified 11 studies involving 106 patients aged between 22 and 72 years. Predonation and bench stone surgery was performed in 9 (8.5%) and 96 (90.6%) patients, respectively. Predonation stone surgery involved extracorporeal shock wave lithotripsy, retrograde intrarenal surgery, and percutaneous nephrolithotomy in 8, 1, and 1 patient, respectively. The overall success rate of predonation stone surgery was 78%, and the complication rate was 0%. Bench stone surgery involved ureteroscopy, pyelolithotomy, or a combination of both in 79 (82.3%), 10 (10.4%), and 7 (7.3%) cases, respectively, with an overall success rate of 95.8% and an overall complication rate of 9.37%.

CONCLUSIONS

Predonation and bench stone surgery in grafts from living donors represents efficacious and safe procedures. Further studies on wider series with a longer follow-up are required.

Physical activity in elderly kidney transplant patients with multiple renal arteries

INTRODUCTION

Kidney transplantation (KT) is the gold standard for treatment of patients with end- stage-renal disease. To expand the donor reserve, it is necessary to use marginal/suboptimal kidneys.

METHODS

We retrospectively evaluated the short/long-term outcome of 34 KT elderly patients who received allografts with vascular abnormalities (MRA group), in comparison with 34 KT patients who received a kidney with a single renal artery (SRA group) pair-matched by age, length of time on dialysis, comorbidity and donor age.

RESULTS

All participants completed the International Physical Activity Questionnaire at KT, and then 4, 8, and 12 weeks after transplantation. Our data indicate that kidney with vascular anatomical variants may be successfully transplanted, since the overall rate of surgical complications was 20.6% in the SRA group and 17.6% in the MRA group and that the 5-year survival rate after KT was 100% in both groups.

CONCLUSIONS

The data also underline that individualized physical activity programs induced similar excellent results in both groups, improving physical capacities, arterial pressure, lipid metabolism, insulin sensitivity, quality of life and physical and mental status.

Relation Between Wound Complication and Lymphocele After Kidney Transplantation: A Monocentric Study

INTRODUCTION

Wound complication frequently arises after kidney transplantation and its risk factors are well known. In a previous paper we analyzed these factors, and in this new retrospective study we evaluate the influence of lymphocele in the development of wound complications.

PATIENTS AND METHODS

From January 2000 to December 2018, 731 consecutive kidney transplants have been performed in our center. We have analyzed the incidence of wound complication and lymphocele and their risk factors.

RESULTS

Out of 731 kidney transplants, we have observed wound complications in 115 patients (15.7%) and lymphocele in 158 patients (21.7%). Of these, 70 patients developed both complications (9.5%), but 6 patients have been excluded because they were in therapy with mammalian target of rapamycin inhibitors. Twenty-nine patients (45.3%) presented a first level and 35 patients (54.7%) showed second level wound complications. Lymphocele was the only present factor in just 3 cases (4.6%). The other patients showed diabetes in 28 cases (43.7%), overweight/obesity in 38 (59.3%), delayed graft function in 17 (26.5%), and 60 years or more in 38 (57.8%). The association has been found in 30 out 64 patients treated with tacrolimus (46.8%) and in 34 with cyclosporine (53.1%); 40 patients did not receive muscular layer's reconstruction (62.5%).

CONCLUSION

Our experience shows that lymphocele alone is not a predisposing factor for wound dehiscence after kidney transplantation, and they often coexist because they share the same risk factors, the most important being obesity, diabetes and delayed graft function, older age, and surgical techniques. No relation has been observed with calcineurin inhibitor therapy.

Colorectal Cancer in the Elderly Patient: The Role of Neo-adjuvant Therapy

Background

Neoadjuvant chemoradiotherapy has a significant role in downstaging cancer. It improves the local control of the disease and can make conservative resection of rectal cancer possible.

Methods

We enrolled 114 patients with subperitoneal rectal cancer who underwent neoadjuvant chemoradio-therapy and radical excision with total mesorectal excision (TME). The primary endpoint was oncological outcomes and the secondary endpoint was surgical outcomes.We evaluate the experience of a multidisciplinary team and the role of neoadjuvant chemoradiotherapy in integrated treatment of cancer of the subperitoneal rectum.

Results

Surgical procedures performed were abdominal perineal resection in 4 cases (3.5%), anterior resection in 89 cases (78%), Hartmann’s procedure in 5 cases (4.4%), and ultralow resection with coloanal anastomosis and diverting stoma in 16 patients (14%).

Local recurrence occurred in 6 patients (5.2%), the overall survival was 71.9% at 5 years and disease-free survival was about 60%.

Conclusions

The effect of pathological downstaging amounted to 58.8%, including cPR. The pathologic complete remission occurred in 8.8% of cases.

The outcomes of neoadjuvant therapy can be achieved when this treatment is associated with correct surgical technique with TME and the prognosis is defined by an anatomopathological examination performed according to Quirke’s protocol.

Our Timing to Remove Peritoneal Catheter Dialysis After Kidney Transplant

BACKGROUND

Patients on peritoneal dialysis treatment represent 15% of the global dialysis population. The major complication of peritoneal dialysis is catheter and peritoneal infection. Peritoneal dialysis patients who receive kidney transplants are at increased risk of infection because of immunosuppressive therapy.

AIM

The purpose of this study is to show our ideal timing to remove peritoneal catheter after kidney transplant, which gives adequate security on renal function recovery and reduction of septic risk.

METHOD OF STUDY

We analyzed the outcomes of 65 patients on peritoneal dialysis who underwent kidney transplant between 2000 and 2016.

RESULTS

In 61 cases there was an immediate graft functional recovery. In 4 cases there was a delayed graft function (DGF), and we performed a hemodialysis with temporary placement of a venous catheter. In all patients we removed peritoneal dialysis catheter 30 to 45 days after transplant. There has been 1 case of catheter infection, which was treated with antibiotic therapy.

DISCUSSION

Our average time to remove the peritoneal dialysis catheter was shorter than times in previous studies, between the 30th and 45th postoperative day. In the 4 cases in which there has been a DGF, we performed hemodialysis treatment to avoid, in the immediate postoperative period, direct insults to the peritoneum by local dialysis procedures.

CONCLUSION

Our experience show that the 30th to 45th postoperative day is a good time frame, better yet a good watershed between the safe removal of peritoneal catheter when patients have a stabilized renal function and the possibility of leaving it in situ, to resume peritoneal dialysis in case of persistent DGF.

Pisa syndrome. Report of a case

Very few cases of Pisa syndrome have been reported. The syndrome consists of dystonic symptoms, namely, tonic flexion of the trunk to one side and its slight rotation. It appears to be a side effect of prolonged antipsychotic therapy. We report on a case of Pisa syndrome in which withdrawal significantly improved the dystonic symptoms. However, a severe exacerbation of schizophrenic symptoms required the immediate resumption of neuroleptic therapy which was followed by the reappearance of dystonic symptoms. Associated anticholinergic medication led to only a slight improvement.

[Neurological complications in Behçet's disease]

A case of unusual Neuro-Behçet syndrome is reported. Four years of follow-up revealed at beginning later the occurrence of acute meningoencephalitis caractherized by two convulsive fits. CSF examination revealed high albumin and cells contents. CT examination of the head was negative. Incomplete clinical improvement was obtained by using steroids. Differential diagnosis is finally discussed.

Familial hypokalemic paralysis: a case study

A case of hypokalemic periodic paralysis, is reported, characterized by a positive family history and by repeated attacks of transient motor weakness since the age of 14 involving one all limbs. An induction test under ECG and EMG monitoring, carried out by infusing glucose and insulin when the patient was symptom-free, provoked motor paresis comparable to the spontaneous attacks and confirmed the diagnosis.
