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.
Introduction: Laparoscopic liver resections (LLR) of colorectal metastasis located in posterosuperior segments (1, 4A, 7 and 8) are challenging and highly demanding. The aim of our study is to determine the safety and feasibility of hand-assisted laparoscopic surgery (HALS) in the resections of the posterosuperior lesions and to compare the peri-operative, short-term and long-term outcomes with the open liver resection (OLR) approach.Methods and Results: A retrospective study of patients who underwent either HALS or OLR for metastatic colorectal cancer (mCRC) located in the posterosuperior segments of the liver between 2008 and 2018 in two university affiliated medical centers.Results: A total of 187 patients were identified, of whom 78 underwent HALS and 109 underwent OLR. There was no difference between the HALS and OLR with regard to preoperative factors (age, primary CRC tumor location, number and anatomical distribution of liver metastasis, pre-operative neo-adjuvant treatment, operative time, blood transfusion rate, and resection margins positivity). On the other hand, HALS compared to OLR had a significantly shorter mean hospital stay (4 vs. 6 days; P = 0.003), and a lower total complications rate (25 vs. 47% P = 0.006). Both groups had no 30-day mortality. Also, patients who underwent HALS vs. OLR had similar liver metastases recurrence (55 vs. 51%. P = 0.65) and 5-year survival (47 vs. 45%. P = 0.72).Conclusions: HALS for mCRC located in posterosuperior liver segments is safe and feasible and it is a preferable approach due to its lower complication rate and shorter hospital stay while not compromising survival and disease recurrence.
(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.
(1) Background: There is an abundance of literature available on predictors of survival for patients with colorectal liver metastases (CRLM) but minimal information available on the relationship between the primary tumor location and CRLM survival. The studies that focus on the primary tumor location and CRLM survival exhibit a great deal of controversy and inconsistency with regard to their results (some studies show statistically significant connections between the primary tumor location and prognosis versus other studies that find no significant relationship between these two factors). Furthermore, the majority of these studies have been conducted in the West and have studied more diverse and heterogenous populations, which may be a contributing factor to the conflicting results. (2) Methods: We included patients who underwent liver resection for CRLM between December 2004 and January 2019 at two university-affiliated medical centers in Israel: Carmel Medical Center (Haifa) and Rabin Medical Center (Petach Tikvah). Primary tumors located from the cecum up to and including the splenic flexure were labeled as right-sided primary tumors, whereas tumors located from the splenic flexure down to the anal verge were labeled as left-sided primary tumors. (3) Results: We identified a total of 501 patients. Of these patients, 225 had right-sided primary tumors and 276 had left-sided primary tumors. Patients with right-sided tumors were significantly older at the time of liver surgery compared to those with left-sided tumors (66.1 + 12.7 vs. 62 + 13.1, p = 0.002). Patients with left-sided tumors had slightly better overall survival rates than those with right-sided tumors. However, the differences were not statistically significant (57 vs. 50 months, p = 0.37 after liver surgery). (4) Conclusions: The primary tumor location does not significantly affect patient survival after liver resection for colorectal liver metastasis in the Mediterranean population.
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.
