Patients who underwent laparoscopic multivisceral resection for clinical T4b colorectal cancer

Patients who underwent open multivisceral resection for clinical T4b colorectal cancer

The laparoscopic approach was used for the treatment of clinical T4b colorectal cancer

Laparoscopic surgery

This study attempts to compare safety and long-term oncological outcomes between laparoscopic surgery and open surgery in the treatment of clinical T4b Colorectal cancer.

Laparoscopic surgery is controversial for patients with T4b colorectal cancer who require multivisceral resection. With the expansion of the indications for laparoscopic surgery in recent years, surgeons try to perform laparoscopic multivisceral resection for the treatment of clinical T4b colorectal cancer. In this study, investigators attempted to compare safety and long-term oncological outcomes between laparoscopic surgery and open surgery in the treatment of clinical T4b colorectal cancer.

This study was a multicenter retrospective cohort study based on a multicenter database which contained hospitalization. According to the operation method, the patients were divided into laparoscopic multivisceral resection group(patients who underwent laparoscopic surgery or conversion to open surgery) and open multivisceral resection group(patients who underwent open surgery directly). The short-term and long-term result was compared between groups.

Blood loss is defined as intraoperative blood loss and measured in milliliters(ml).

Complications are defined as all surgery-related adverse events postoperatively, such as anastomotic leak, infection, which are measured in frequency.

Hospital stay after surgery is defined as the length of time from the end of surgery to the discharge of patient, which is measured in days.

Overall survival is defined as the time from the surgery to death or last follow-up, regardless of disease recurrence, which was measured in months.

Disease-free survival is defined as the time from the surgery to disease recurrence or last follow-up, which was measured in months.

Patients with Renal tumor are randomized into this group,they will received laparoscopic partial nephrectomy. During operation, the technique of segmental renal artery clamping will performed.

Patients with renal tumor are randomized into this group,they will received laparoscopic partial nephrectomy. During operation, the technique of traditional main renal artery clamping will be performed.

Laparoscopic partial nephrectomy with segmental artery clamping will be performed for patients enrolled in this group.

The purpose of this study is to compare the efficacy and safety of the segmental artery clamping and main renal artery clamping during laparoscopic partial nephrectomy

Renal tumor patients,for whom laparoscopic partial nephrectomy is suitable, will be randomly divided into two groups,segmental artery clamping group and main artery clamping group. All procedures were performed by the same laparoscopic surgeon. Blood loss, operation time, warm ischemia time, complications and affected renal function before and after operation will be recorded and compared. The safety and efficiency of laparoscopic partial nephrectomy with segmental renal artery clamping will be evaluated in comparison with the conventional main renal artery clamping technique.
