Feasibility and Short-Term Outcomes in Liver-First Approach: A Spanish Snapshot Study (the RENACI Project).

(1) Background: The liver-first approach may be indicated for colorectal cancer patients with synchronous liver metastases to whom preoperative chemotherapy opens a potential window in which liver resection may be undertaken. This study aims to present the data of feasibility and short-term outcomes in the liver-first approach. (2) Methods: A prospective observational study was performed in Spanish hospitals that had a medium/high-volume of HPB surgeries from 1 June 2019 to 31 August 2020. (3) Results: In total, 40 hospitals participated, including a total of 2288 hepatectomies, 1350 for colorectal liver metastases, 150 of them (11.1%) using the liver-first approach, 63 (42.0%) in hospitals performing <50 hepatectomies/year. The proportion of patients as ASA III was significantly higher in centers performing ≥50 hepatectomies/year (difference: 18.9%; p = 0.0213). In 81.1% of the cases, the primary tumor was in the rectum or sigmoid colon. In total, 40% of the patients underwent major hepatectomies. The surgical approach was open surgery in 87 (58.0%) patients. Resection margins were R0 in 78.5% of the patients. In total, 40 (26.7%) patients had complications after the liver resection and 36 (27.3%) had complications after the primary resection. One-hundred and thirty-two (89.3%) patients completed the therapeutic regime. (4) Conclusions: There were no differences in the surgical outcomes between the centers performing <50 and ≥50 hepatectomies/year. Further analysis evaluating factors associated with clinical outcomes and determining the best candidates for this approach will be subsequently conducted.

Atypical double colorectal metastasis: spleen and uterus.

Oligometastatic disease is a relatively new concept that refers to an intermediate stage between disseminated and localized cancer. Most frequent locations for colorectal metastasis are lung and liver. We present an a typical case of an 85-year-old woman who was diagnosed with a low-grade adenocarcinoma in left colon; she underwent a left laparoscopic hemicolectomy which resulted in a stage IIIb. After 24 months of follow-up, an increase of carcinoembryonic antigen (CEA) leads to the diagnosis of two metastatic lesions in two uncommon locations: spleen and myometrium. Stepwise surgical resection of both lesions was performed without complications. Spleen and uterus are organs that are rarely affected in colorectal cancer, the affection of both organs being even more infrequent. Despite the atypicality, surgical treatment is a valid strategy in this case of oligometastatic disease, which enables the disease-free survival of the patients.

Robotic versus laparoscopic distal pancreatectomies: A systematic review and meta-analysis on costs and perioperative outcome.

AIM: The aim of this meta-analysis is to compare perioperative outcomes and costs of robotic and laparoscopic distal pancreatectomy (RDP and LDP). MATERIAL AND METHODS: In accordance with the PRISMA guidelines, we searched Medline, EMBASE, Cochrane and Web of Science for reports published before December 2020. RESULTS: The literature search identified 11 papers (1 187 patients). RDP showed a lower conversion rate (odds ratio: 2.56, 95% confidence intervals [CI]: 1.31 to 5.00) with no significant differences in bleeding and operative time, complications ≥ Clavien-Dindo grade III, pancreatic fistulas and length of stay. Despite RDP presenting higher costs in all included studies, none of these differences were significant. However, RDP showed higher total costs than LDP (standardized mean differences [SMD]: -1.18, 95% CI: -1.97 to -0.39). A subgroup analysis according to the continent of origin showed that studies coming from Asian research groups kept showing significant differences (SMD: -2.62, 95% CI: -3.38 to -1.85), while Western groups did not confirm these findings. CONCLUSION: Based on low-quality evidence, despite some potential technical advantages, RDP still seems to be costlier than LDP.
