Background
The aim of the study is to analyze the feasibility, the safety and short- and medium-term survival of totally laparoscopic simultaneous resections (LSR) of colorectal cancer (CRC) and ...synchronous liver metastases (LM).
Methods
This is a retrospective study of a single-center series. Patients ASA IV, ECOG ≥ 2, major hepatectomies (≥ 3 segments), symptomatic CRC as well as low rectal tumors were excluded from indication. The difficulty level of all liver resections was classified as low or intermediate according to the Iwate Criteria. Dindo–Clavien classification for postoperative complications evaluation was used.
Results
15 Patients with 21 liver lesions were included. Laparoscopic liver surgery was performed first in every case. Median size of the lesions was 20 mm (r 8–69). Major complications (Dindo–Clavien ≥ 3) occurred in 3 patients (20%); median hospital stay was 7 days (r 4–35), and only one patient (6.6%) was readmitted upon the first month from the surgery. 90-day mortality rate was 0%. After a median follow-up of 24 months (r 7–121), disease-free survival at 1, 2 and 3 years was 58%, 36% and 24%, respectively; overall survival at 1, 2 and 3 years was 92.3%.
Conclusions
In selected patients, LSR of CRC and LM is technically feasible and has an acceptable morbidity rate and mid-term survival.
Background
Historically , liver metastases due to melanoma have been associated with dismal prognosis. Moreover, the actual survival benefit from the treatment of melanoma liver metastases is still ...controversial. Hence, this study aims to evaluate the difference in surgical versus non-surgical options for melanoma liver metastases.
Methods
Four databases (PubMed, EMBASE, Scopus, and Cochrane Library) were searched from inception to July 17, 2022. Studies were included if they compared outcomes between surgical and non-surgical treatment for patients with liver metastases from resectable melanoma. Meta-analyses were performed for the outcomes of 1-year, 2-year, 3-year and 5-year OS. Sensitivity analyses were performed for outcomes with substantial statistical heterogeneity. To account for possible moderators that might contribute to statistical heterogeneity, univariate meta-regression with mixed-effects models and subgroup analyses were conducted for the outcome of 2-year OS.
Results
The search yielded 6610 articles; 13 studies were included in our analysis. Meta-analyses showed that survival outcomes were in favour of patients undergoing surgery as compared to non-surgery: 1-year OS (HR = 0.29, 95%CI 0.19–0.44,
p
< 0.00001), 2-year OS (HR = 0.19, 95%CI 0.09–0.38,
p
< 0.00001), 3-year OS (HR = 0.07, 95%CI 0.03–0.19,
p
< 0.00001) and 5-year OS (HR = 0.07, 95%CI 0.02–0.22,
p
< 0.00001). All included studies were of high quality. There was moderate-to-high statistical heterogeneity. Findings were robust to sensitivity analyses. Subgroup analyses and univariate meta-regression revealed neoadjuvant therapy and age as statistically significant subgroup and moderator respectively.
Conclusions
This study suggests that surgical treatment of melanoma liver metastases could offer better OS outcomes compared with non-surgical treatment.
Minimally invasive right posterior sectionectomy (RPS) is a technically challenging procedure. This study was designed to determine outcomes following robotic RPS (R-RPS) and laparoscopic RPS ...(L-RPS).
An international multicentre retrospective analysis of patients undergoing R-RPS versus those who had purely L-RPS at 21 centres from 2010 to 2019 was performed. Patient demographics, perioperative parameters, and postoperative outcomes were analysed retrospectively from a central database. Propensity score matching (PSM) was performed, with analysis of 1 : 2 and 1 : 1 matched cohorts.
Three-hundred and forty patients, including 96 who underwent R-RPS and 244 who had L-RPS, met the study criteria and were included. The median operating time was 295 minutes and there were 25 (7.4 per cent) open conversions. Ninety-seven (28.5 per cent) patients had cirrhosis and 56 (16.5 per cent) patients required blood transfusion. Overall postoperative morbidity rate was 22.1 per cent and major morbidity rate was 6.8 per cent. The median postoperative stay was 6 days. After 1 : 1 matching of 88 R-RPS and L-RPS patients, median (i.q.r.) blood loss (200 (100-400) versus 450 (200-900) ml, respectively; P < 0.001), major blood loss (> 500 ml; P = 0.001), need for intraoperative blood transfusion (10.2 versus 23.9 per cent, respectively; P = 0.014), and open conversion rate (2.3 versus 11.4 per cent, respectively; P = 0.016) were lower in the R-RPS group. Similar results were found in the 1 : 2 matched groups (66 R-RPS versus 132 L-RPS patients).
R-RPS and L-RPS can be performed in expert centres with good outcomes in well selected patients. R-RPS was associated with reduced blood loss and lower open conversion rates than L-RPS.
Purpose
Bilateral nephrectomy is performed at times with renal transplantation. Though surgical indications and timing of these two procedures have been described, there are no large case series ...describing the anesthetic management of these cases. We sought to describe our experience.
Methods
We performed a historical cohort study on 54 consecutive cases of simultaneous bilateral nephrectomy with renal transplantation at a single, tertiary-care medical centre. Descriptive statistics were used.
Results
The most common etiology of kidney disease involved was autosomal dominant polycystic kidney disease at 52/54 (96%) cases. All patients received grafts from living donors. An arterial line was placed in 44 (81%) and a central venous catheter in 16 (30%) subjects. At least one vasopressor infusion was used in 44 (81%) cases and 37 (69%) patients required admission to the intensive care unit (ICU). Of this subset, 30 (81%) were admitted for ongoing vasopressor support and six (16%) for hemodynamic monitoring. All patients were extubated in the operating room upon completion of the procedure. Median interquartile range (IQR) ICU length of stay (LOS) was 0.9 0.7–1.4 days and total hospital LOS was 4.4 4.3–5.4 days. There were no cases of mortality at 30 days or of postoperative dialysis.
Conclusions
Adult patients undergoing simultaneous bilateral nephrectomy with renal transplantation often developed perioperative hypotension requiring vasopressor infusions and postoperative transfer to the ICU. This is possibly due to a temporary loss of the renin-angiotensin system. Despite this, patients most commonly were transferred to the floor on postoperative day 1 and had successful outcomes with no mortality at 30 days.
BACKGROUNDLimited liver resections (LLRs) for tumours located in the posterosuperior segments of the liver are technically demanding procedures. This study compared outcomes of robotic (R) and ...laparoscopic (L) LLR for tumours located in the posterosuperior liver segments (IV, VII, and VIII). METHODSThis was an international multicentre retrospective analysis of patients who underwent R-LLR or L-LLR at 24 centres between 2010 and 2019. Patient demographics, perioperative parameters, and postoperative outcomes were analysed; 1 : 3 propensity score matching (PSM) and 1 : 1 coarsened exact matching (CEM) were performed. RESULTSOf 1566 patients undergoing R-LLR and L-LLR, 983 met the study inclusion criteria. Before matching, 159 R-LLRs and 824 L-LLRs were included. After 1 : 3 PSM of 127 R-LLRs and 381 L-LLRs, comparison of perioperative outcomes showed that median blood loss (100 (i.q.r. 40-200) versus 200 (100-500) ml; P = 0.003), blood loss of at least 500 ml (9 (7.4 per cent) versus 94 (27.6 per cent); P < 0.001), intraoperative blood transfusion rate (4 (3.1 per cent) versus 38 (10.0 per cent); P = 0.025), rate of conversion to open surgery (1 (0.8 per cent) versus 30 (7.9 per cent); P = 0.022), median duration of Pringle manoeuvre when applied (30 (20-46) versus 40 (25-58) min; P = 0.012), and median duration of operation (175 (130-255) versus 224 (155-300); P < 0.001) were lower in the R-LLR group compared with the L-LLR group. After 1 : 1 CEM of 104 R-LLRs with 104 L-LLRs, R-LLR was similarly associated with significantly reduced blood loss and a lower rate of conversion to open surgery. CONCLUSIONBased on a matched analysis of well selected patients, both robotic and laparoscopic access could be undertaken safely with good outcomes for tumours in the posterosuperior liver segments.
The present study aims to assess the results obtained after surgical treatment of cholangiocarcinoma (CC) recurrences.
We carried out a single-center retrospective study, including all patients with ...recurrence of CC. The primary outcome was patient survival after surgical treatment compared with chemotherapy or best supportive care. A multivariate analysis of variables affecting mortality after CC recurrence was performed.
Eighteen patients were indicated surgery to treat CC recurrence. Severe postoperative complication rate was 27.8% with a 30-day mortality rate of 16.7%. Median survival after surgery was 15 months (range 0-50) with 1- and 3-year patient survival rates of 55.6% and 16.6%, respectively. Patient survival after surgery or CHT alone, was significantly better than receiving supportive care (p< 0.001). We found no significant difference in survival when comparing CHT alone and surgical treatment (p=0.113). Time to recurrence of <1 year, adjuvant CHT after resection of the primary tumor and undergoing surgery or CHT alone versus best supportive care were independent factors affecting mortality after CC recurrence in the multivariate analysis.
Surgery or CHT alone improved patient survival after CC recurrence compared to best supportive care. Surgical treatment did not improve patient survival compared to CHT alone.
Previous studies have linked obesity to poor outcomes in renal transplant recipients, prompting many transplant centers to encourage weight loss pretransplant in obese patients. Here, we performed a ...single-center retrospective study to assess the effects of weight loss on graft and patient outcomes.
Data from 893 renal transplant recipients at our center from 2007 to 2011 were analyzed. First, renal transplant recipients with a history of obesity before transplant (42%) were compared with nonobese patients. Second, in the obese group, renal transplant recipients with significant weight loss (> 10%) before transplant were compared with other obese renal transplant recipients without significant weight loss.
Renal transplant recipients were predominantly white, with 74% having undergone living-donor transplant. Obese patients were older (56.6 vs 46.7 y old) and had more comorbidities and more surgical complications, in particular wound complications and incisional hernias, posttransplant than nonobese patients (14.7 vs 5.5%, respectively). Patient and graft survival rates were similar to those in nonobese patients. In the obese group, patient characteristics and medical or surgical complications after transplant did not differ between those with or without significant weight loss. However, obese patient and graft survival rates were lower in patients with weight loss than in obese patients without weight loss.
In our study, weight loss before transplant surgery in obese patients had no influence on surgical outcomes but was associated with a higher mortality rate. A prospective assessment of the impact of weight loss before surgery is needed to establish its usefulness.
To describe our technique of simultaneous hand-assisted laparoscopic bilateral native nephrectomy (BNN) and kidney transplantation (KT) in patients with autosomal dominant polycystic kidney disease ...and present our experience.
We retrospectively reviewed a cohort of adult ESRD patients with symptomatic autosomal dominant polycystic kidney disease who underwent a hand-assisted laparoscopic BNN at the time of KT. We reviewed patients’ and donor characteristics, and perioperative and postoperative outcomes.
A total of 52 patients underwent hand-assisted laparoscopic BNN at the time of KT from January 2014 to October 2019. The median age of the recipients was 53.4 years, 57.7% were males, and the median body mass index was 29.0 kg/m2. All but one received a kidney from a living donor and the majority (86.5%) were pre-emptive. One patient required a small bowel resection due to an intraoperative small bowel injury. There was no solid organ injury during the procedure. All patients showed immediate allograft function and a steady decline in serum creatinine. The median decline in the creatinine and hemoglobin on day 1 was 1.2 mg/dL (inter quartile range 0.6-2.3) and 2.2 g/dL (inter quartile range 1.4-3.0), respectively.
Simultaneous hand-assisted laparoscopic bilateral nephrectomy with KT through a modified Gibson incision is feasible and safe in the hands of an experienced laparoscopic surgeon without compromising allograft function.
