Laparoscopic surgery versus open surgery for colon cancer: short-term outcomes of a randomised trial

BACKGROUND: The safety and short-term benefits of laparoscopic colectomy for cancer remain debatable. The multicentre COLOR (COlon cancer Laparoscopic or Open Resection) trial was done to assess the safety and benefit of laparoscopic resection compared with open resection for curative treatment of patients with cancer of the right or left colon. METHODS: 627 patients were randomly assigned to laparoscopic surgery and 621 patients to open surgery. The primary endpoint was cancer-free survival 3 years after surgery. Secondary outcomes were short-term morbidity and mortality, number of positive resection margins, local recurrence, port-site or wound-site recurrence, metastasis, overall survival, and blood loss during surgery. Analysis was by intention to treat. Here, clinical characteristics, operative findings, and postoperative outcome are reported. FINDINGS: Patients assigned laparoscopic resection had less blood loss compared with those assigned open resection (median 100 mL [range 0-2700] vs 175 mL [0-2000], p<0.0001), although laparoscopic surgery lasted 30 min longer than did open surgery (p<0.0001). Conversion to open surgery was needed for 91 (17%) patients undergoing the laparoscopic procedure. Radicality of resection as assessed by number of removed lymph nodes and length of resected oral and aboral bowel did not differ between groups. Laparoscopic colectomy was associated with earlier recovery of bowel function (p<0.0001), need for fewer analgesics, and with a shorter hospital stay (p<0.0001) compared with open colectomy. Morbidity and mortality 28 days after colectomy did not differ between groups. INTERPRETATION: Laparoscopic surgery can be used for safe and radical resection of cancer in the right, left, and sigmoid colon.     

Left jackknife position: a novel position for laparoscopic hepatectomy

Background:Laparoscopic hepatectomy for hepatocellular carcinoma (HCC) located in segment Ⅵ,Ⅶ,or Ⅷ of the liver is usually difficult because of poor operative exposure,due to the unique anatomical structure.In this study,we evaluated the practice of laparoscopic hepatectomy with the left jackknife position for patients with HCC located in segment Ⅵ,Ⅶ,or Ⅷ.Methods:A total of 10 patients were enrolled to undergo laparoscopic hepatectomy with the left jackknife position.Tumors located in segment Ⅵ,Ⅶ,or Ⅷ were assessed by preoperative dynamic computed tomography or magnetic resonance imaging.Operation time,intraoperative blood loss,postoperative fasting time,postoperative drainage time,major postoperative complications,and duration of postoperative hospital stay were recorded.Results:All surgeries were successfully completed.None of the patients required conversion to open surgery during the procedure,and no serious postoperative complications were observed.The median tumor size was 31 mm (range 23-41 mm) in diameter,the mean operation time was 166 ± 38 min,the mean intraoperative blood loss was 220 ± 135 mL,and the median postoperative hospital stay was 4 days (range 2-7 days).Conclusions:For HCC located in segment Ⅵ,Ⅶ,or Ⅷ,laparoscopic hepatectomy with this novel position—the left jackknife position—is safe and effective during tumor resection by exposing a sufficient operating field.     

Laparoscopic hepatectomy for liver neoplasms in 15 cases

Objective

The aim of our study was to retrospectively analyze 15 patients’ clinical materials with laparoscopic resection of liver neoplasms.

Methods

From December 2007, a total of 15 patients with liver neoplasms were performed with laparoscopic hepatectomy, and their clinical materials, perioperative dates, postoperative complications, postoperative recovery and short-term curative effects were analyzed and summarized respectively.

Results

Laparoscopic hepatectomy (LH) were performed in 15 patients, including 1 case underwent laparoscopic hepatic left lobectomy, 1 case of left lateral hepatectomy, 13 cases of partial liver resection. Fourteen cases of total laparoscopic liver resections for liver neoplasms, 1 case of hand-assisted laparoscopic liver resection of the tumor, there was no conversion to open approach. Of the 15 patients with liver neoplasms, 13 cases of hepatic neoplasms with the maximum diameter was 8 cm × 8 cm × 9 cm, 9 cases of the borderline micro hepatocellular carcinoma (MHCC) with the diameter not more than 2 cm, 3 cases of hepatic benign tumor. The mean operation time was (120 ± 30) min, and the intraoperative average hemorrhage was 100 mL, beginning to eat and get out of bed following 1–2 days of operation. The average postoperative hospitalization was 8 days, WBC, ALT, AST, albumin, bilirubin returned to normal after one week of operation. There were no postoperative complications such as hemorrhage, bile leakage or air embolism etc. Twelve patients with HCC were confirmed by postoperative pathology, 1 case of liver smooth muscle lipoma, 2 case of hepatic hemangioma. By one year of followed-up in 12 cases of HCC, the longest survival was 38 months, and no recurrence or death, 1 year survival rate was 100%.

Conclusion

Among the choice of cases, the advantages of LH for liver neoplasms compared with open surgery were less trauma, faster recovery and less blood loss. it is safe and effective for choosing a reasonable surgical indication, especially for peripheral micro hepatocellular carcinoma.

Prospective,single-center cohort study analyzing the efcacy of complete laparoscopic resection on recurrent hepatocellular carcinoma

Background: Laparoscopic hepatectomy is increasingly being used to treat hepatocellular carcinoma (HCC). How?ever, few studies have examined the treatment of recurrent HCC in patients who received a prior hepatectomy. The present prospective study compared the clinical efcacy of laparoscopic surgery with conventional open surgery in HCC patients with postoperative tumor recurrence. Methods: We conducted a prospective study of 64 patients, all of whom had undergone open surgery once before, who were diagnosed with recurrent HCC between June 2014 and November 2014. The laparoscopic group (n = 31)underwent laparoscopic hepatectomy, and the control group (n tion time, intraoperative blood loss, surgical margins, postoperative pain scores, postoperative time until the patient= 33) underwent conventional open surgery. Opera?could walk, anal exsufation time, length of hospital stay, and inpatient costs were compared between the two groups. The patients were followed up for 1 year after surgery, and relapse?free survival was compared between the two groups. Results: All surgeries were successfully completed. No conversion to open surgery occurred in the laparoscopic group, and no serious postoperative complications occurred in either group. No significant difference in inpatient costs was found between the laparoscopic group and the control group (P = 0.079), but significant differencesbetween the two groups were observed for operation time (116.7 ± 37.5 vs. 148.2 ± 46.7 min, P = 0.031), intraopera?tive blood loss (117.5 ± 35.5 vs. 265.9 ± 70.3 mL, P = 0.012), postoperative time until the patient could walk (1.6 ± 0.6vs. 2.2 ± 0.8 days, P < 0.05), anal exsufation time (2.1 ± 0.3 vs. 2.8 ± 0.7 days, P = 0.041), visual analogue scale pain score (P < 0.05), postoperative hepatic function (P < 0.05), and length of hospital stay (4.5 ± 1.3 vs. 6.0 ± 1.2 days,P= 0.014). During the 1?year postoperative follow?up period, 6 patients in each group had recurrent HCC on the side of the initial operation, but no significant difference between groups was observed in the recurrence rate or relapse?free survival. In the laparoscopic group, operation time, postoperative time until the patient could walk, anal exsufation time, and inpatient costs were not different (P > 0.05) between the patients with contralateral HCC recur?rence (n = 18) and those with ipsilateral HCC recurrence (n = 13). However, intraoperative blood loss was signifi?cantly less (97.7 ± 14.0 vs. 186.3 ± 125.6 mL, P = 0.012) and the hospital stay was significantly shorter (4.2 ± 0.7 vs. 6.1 ± 1.7 days, P = 0.021) for the patients with contralateral recurrence than for those with ipsilateral recurrence. Conclusions: For the patients who previously underwent conventional open surgical resection of HCC, complete laparoscopic resection was safe and effective for recurrent HCC and resulted in a shorter operation time, less intraop?erative blood loss, and a faster postoperative recovery than conventional open surgery. Laparoscopic resection was especially advantageous for the patients with contralateral HCC recurrence.

Laparoscopic liver resection versus open liver resection for intrahepatic cholangiocarcinoma: 3-year outcomes of a cohort study with propensity score matching

IntroductionLaparoscopic liver resection(LLR) for intrahepatic cholangiocarcinoma is debatable due to technical challenges associated with major hepatectomy and lymph node dissection. This study aims to analyze the long-term outcomes with propensity score matching.MethodsPatients who underwent liver resection for intrahepatic cholangiocarcinoma from August 2004 to October 2015 were enrolled. Those who had combined hepatocellular-cholangiocarcinoma and palliative surgery were excluded. Medical records were reviewed for postoperative outcome, recurrence, and survival. The 3-year disease-free survival(DFS) and 3-year overall survival(OS) were set as the primary endpoint, and 3-year disease-specific survival, 1-year OS, 1-year DFS, operative outcome, and postoperative complications were secondary endpoints.ResultsA total of 91 patients were enrolled with 61 in the open group and 30 in the laparoscopic group. Propensity score matching included 24 patients in both groups. In total, the 3-year OS was 81.2% in the open group and 76.7% in the laparoscopic group(p = 0.621). For 3-year DFS, open was 42.5% and laparoscopic was 65.6%(p = 0.122). Mean operation time for the open group was 343.2 ± 106.0 min and laparoscopic group was 375.2 ± 204.0 min(p = 0.426). Hospital stay was significantly shorter in the laparoscopic group(9.8 ± 5.1 days) than the open group(18.3 ± 14.7, p=<0.001). There was no difference in complication rate and 30-day readmission rate. Tumor size, nodularity, and presence of perineural invasion showed an independent association with the 3-year DFS in multivariate analysis.ConclusionLaparoscopic liver resection for intrahepatic cholangiocarcinoma is technically feasible and safe, providing short-term benefits without increasing complications or affecting long-term survival.     

Morbidity and mortality of laparoscopic vs. open radiofrequency ablation for hepatic malignancies.

AIMS: Surgical radiofrequency ablation (RFA) of hepatic malignancies is associated with superior oncological outcome as compared to percutaneous RFA. The aim of this prospective non-randomized cohort study was to compare morbidity and mortality of laparoscopic (LRFA) vs. open (ORFA) radiofrequency ablation of liver cancer. METHODS: Between October 1999 and November 2006, RFA was performed in 154 consecutive patients (percutaneous 12, LRFA 93, ORFA 49) for a total of 291 hepatic tumours (HCC 81, colorectal metastases 157, other 53). Seventy-four patients simultaneously underwent additional surgery. Laparoscopic RFA was performed in 45/54 patients with HCC, and in 44/54 patients with cirrhosis. Laparotomy was performed in 14/22 patients who underwent simultaneous colorectal resection, and in 12/22 patients with hepatic resection. RESULTS: Postoperative complications occurred in 25 patients with subsequent mortality in 2. As compared with LRFA, ORFA was associated with significantly (p<0.01) higher intra-operative blood loss (median 20 (range 0-1700) vs. 10 (0-900) ml), longer duration of surgery (180 (25-440) vs. 75 (30-390) min), more postoperative complications (17 vs. 8), and longer postoperative hospital stay (8 (1-127) vs. 4 (1-51) d). According to the therapy-oriented severity grading system (TOSGS) classification, postoperative complications in the ORFA-group were more severe than those in the LRFA-group (p<0.01). These findings were consistent in patients without simultaneous colorectal and/or hepatic resection and in patients with liver tumours measuring 3cm or less. In univariate analysis the following factors were significantly (p<0.01) related to the presence of postoperative complications: simultaneous colorectal resection, laparotomy, duration of surgery, tumour location in right liver, liver segment 7 (p=0.01), absence of cirrhosis (p=0.02), liver segment 8 (p=0.03), and metastatic liver cancer (p=0.04). CONCLUSION: LRFA for hepatic malignancies seems preferable above ORFA, provided good patient selection, surgical expertise, and long-term oncological control.

目的探讨分析腹腔镜下结直肠癌根治的安全性和可行性,对比其与开腹手术的近远期疗效。方法回顾性分析我院2006年1月至2011年12月间结肠及中上段直肠癌根治术患者的临床资料,其中开腹手术120例,腹腔镜下手术76例。分析比较两组患者的临床病理资料、围手术期情况及近远期生存情况。结果两组患者年龄、性别比较无统计学差异。腹腔镜组平均手术时间大于开腹组,分别为(226.28±61.09)min和(193.50±53.79)min;术中失血量腹腔镜组小于开腹组,分别为(84.00±28.41)ml和(187.60±37.27)ml;术后住院时间腹腔镜组小于开腹组,分别为(7.55±2.04)d和(8.40±3.39)d。两组患者肠管近端及远端切缘长度、清扫淋巴结数目以及术后感染性和非感染性并发症发生率比较,差异无统计学意义。开腹组与腹腔镜组结直肠癌患者术后3、5年生存率分别为76.8%、65.7%和76.6%、71.2%(P>0.05);Duke’s A、B、C各期两组患者生存率比较无统计学差异。结论腹腔镜结直肠癌根治手术安全可行,具有出血少、术后恢复快等优点,肿瘤安全性、并发症发生率及术后近远期疗效不亚于开腹手术。     

Advantages of Laparoscopic Abdominoperineal Resection for Anastomotic Recurrence of Rectal Cancer

Background: Surgery offers the only potential for cure and long-term survival of recurrence of rectal cancer.Few studies about laparoscopic recurrent lesion resection have been reported. This study was designed to evaluatethe safety and feasibility of laparoscopic abdomino-perineal resection for anastomotic recurrence of rectal cancer.Materials and Methods: Data for 42 patients with recurrence of rectal cancer were collected retrospectively. Of the42 patients, 22 underwent laparoscopic surgery (LR group) and 20 received open surgery (OR group). Outcomesbetween the two groups were compared. Results: Operation time in LR group was shorter compared with theOR group (164.6±27.7min vs 203.0±45.3min); intra-operative blood loss was 119.7±44.4ml and 185.0±94.0ml inLR group and OR group, respectively (p<0.001); time to first flatus in LR group was shorter than in OR group,and the difference was statistically significant (2.6±0.8 days vs 3.1±0.8 days, p=0.013); hospital stay in the LRand OR groups was 8.6±1.3 days and 9.8±2.2 days; 3-year survival rates in the LR and OR groups were 44.4%and 42.8% (p=0.915) and the 3-year disease-free survival rates were 36.4% and 30.0%, respectively (p=0.737).Conclusions: Laparoscopic abdomino-perineal resection is safe and feasible for anastomotic recurrence of rectalcancer.
