Purpose The aim was to compare the short-term and long-term outcomes of patients with metastatic colorectal cancer (CRC) undergoing laparoscopic versus open colorectal resection with simultaneous resection for liver metastases. Currently there is a lack of studies that have investigated the oncosurgical aspects and the short and long-term outcomes from these procedures. Materials and methods A retrospective study of patients who underwent simultaneous resections for CRC and synchronous liver metastases between 2008 and 2019 in 2 university affiliated medical centers. Results Sixty-three patients were identified of whom 21 had successful laparoscopic simultaneous resections. In 43% of patients, the primary tumor was located in the right colon. The 3-year overall survival and disease-free survival rates were 87% and 48%, respectively. When compared with a separate control group of 42 patients who underwent conventional open resections, the laparoscopic approach was associated with an increased operative time (286 vs. 225 min, P=0.05), but a shorter hospital stay (6 vs. 8 d, P=0.008). Conclusions Simultaneous laparoscopic colorectal and parenchymal sparing liver resection for metastatic CRC is safe, feasible, and it is a preferable approach because of better short-term outcome compared with open surgery while not compromising survival and disease recurrence.

Background Hand-assisted laparoscopic surgery is a widely accepted alternative to an open approach. The use of this technique in repeat liver resection is limited due to technical difficulties caused by postsurgical adhesions. We aimed to assess the feasibility and safety of hand-assisted laparoscopic repeat hepatectomy (HALRH). Materials and methods This was a retrospective study of the medical files of patients who had undergone HALRH between 2010 and 2017 in 2 university-affiliated medical centers. Results Sixteen patients with repeat hepatectomy were included with a median age of 67.5 years. The first liver resection was a traditional laparotomy for 9 patients and hand-assisted laparoscopic surgery for 7 patients. The conversion rate to open surgery was 6%. The median operative time, blood loss during surgery, and postoperative hospital stay were 166 minutes, 400 mL, and 7 days, respectively. R0 resections were achieved in 88% of patients. The median number of tumors and tumor size were 1 and of 25 mm, respectively. There were no mortalities or major complications postoperatively. For patients with colorectal liver metastases, the median follow-up and overall survival were 21 and 43 months, respectively. Conclusion The findings suggest HALRH to be safe and feasible. Future ERAS guidelines should evaluate this approach for liver surgery.

(1) Background: Hand-assisted laparoscopic surgery for liver resection is a globally established technique. In this study, we report on the incidence and risk factors for postoperative incisional hernia (IH) after hand-assisted laparoscopic surgery for colorectal liver metastasis. (2) Methods: This was retrospective analysis of 89 consecutive hand-assisted laparoscopic surgery for colorectal liver metastasis. (3) Results: Participants were 39 females and 50 males. Median age was 65 years, and in 63%, the BMI was ≥25. Postoperative complications were encountered in 18% of the patients. Seven patients (7.8%) had postoperative incisional hernia in the hand port site. There was significantly higher incidence of incisional hernia in overweight patients (BMI ≥ 25) (p = 0.04), and in cases with simultaneous liver and colon resection (p = 0.02). In univariant and multivariant analyses, simultaneous liver and colon resection (p = 0.004 and 0.03, respectively), and platelet-to-lymphocyte ratio ≤ 200 (p = 0.03, 0.04, respectively) were both independent risk factors for developing postoperative incisional hernia. (4) Conclusions: Both simultaneous liver and colon resection, and platelet-to-lymphocyte ratio ≤ 200 are independent risk factors for postoperative incisional hernia after hand-assisted laparoscopic surgery for colorectal liver metastasis.
