INTRODUCTION

This study specifically examined right colonic cancer resection, a common operation for colorectal surgeons starting laparoscopic resection, to assess the impact of commencing laparoscopy.

PATIENTS AND METHODS

A total of 56 patients undergoing open (n = 34) and attempted laparoscopic (n = 22) elective right hemicolectomy for colorectal cancer between November 2003 and March 2007 were compared. Postoperative stay was the primary outcome. Secondary outcomes included analgesic requirements, bowel recovery, morbidity and mortality. Frequency of laparoscopic versus open surgery over time was also examined.

RESULTS

Resections attempted laparoscopically increased from 9.1% to 75% in the first and last quarters of the study period, respectively (P = 0.0002). Uptake of ‘enhanced recovery’ was mainly in the laparoscopic group. Conversion was required in two of 22 patients. Attempted laparoscopic cases had a shorter median postoperative stay (6 vs 10 days; P < 0.0001), duration of parenteral or epidural analgesia (48 vs 72 h; P < 0.0001) and time to first bowel action (3 vs 4 days; P = 0.001) compared with open cases. Demography, tumour characteristics, morbidity and mortality were comparable between groups. Multivariate analysis identified decreased age, attempted laparoscopic surgery, use of enhanced recovery and absence of complications as independently shortening postoperative stay.

CONCLUSIONS

Advantages of laparoscopic surgery and enhanced recovery, even early in a surgeon''s experience, suggest this is the preferred mode for elective right colon cancer resection.  相似文献

随着微创理念的普及,腹腔镜手术已成为右半结肠癌根治切除的标准术式。传统的2D腹腔镜手术虽然仍是目前的主流,但随着技术进步,3D腹腔镜手术的发展同样迅猛。相比传统的2D腹腔镜,其最大的特点在于三维立体视觉效果,使得手术的操作更精细,定位更准确。在右半结肠手术中无论是在解剖层面的拓展,Henle干的处理,淋巴结清扫还是消化道重建方面都有一定的优势。由于3D腹腔镜良好的纵深感和距离感,使得初学者能更快的适应镜下的手眼配合,增加术中操作的稳定性和精确性,减少错误操作,缩短腹腔镜右半结肠癌根治术的学习曲线。  相似文献

Technique and survival after laparoscopically assisted right hemicolectomy   总被引:3,自引:0,他引:3  
Background The role of laparoscopic colon resection in the management of colon cancer is still controversial. In this article, the surgical strategy and techniques are described, with further consideration of the oncologically relevant aspects.Methods Between March 1993 and July 2003, we performed laparoscopic right hemicolectomy in 56 patients with right colon carcinoma. Average age was 74.5 years (range, 17–92). We performed a standardized surgical procedure that included mobilization from the vascularized mesenteric bridges with a window technique, transection of the ileocolic lymphovascular pedicle, and lateral and proximal mobilization of the ileocecum, ascending colon, right flexure, and proximale transversum. After enlargement of one of the trocar incisions the exteriorized colon was resected and an extracorporeal anastomosis was performed in the standard manner.Results There were no conversions to open. The mean operating time was 119 ± 38 min, the mean length of resected colon was 27.8 ± 4.48 cm, and the average width of the clear margins was 6.8 ± 5.3 cm. One patient died. Lymph nodes were positive in 21 patients. The 5-year survival rate in the 48 patients who were operated on with curative intent was 75%. We have had two local recurrences. The overall 5-year mortality-free fraction was 63%. Cox multivariate analysis showed that the mortality-prognostic factors were tumor stage and length of resected colon, whereas Kaplan-Meier analysis showed that the mortality-prognostic factors were positive lymph nodes and tumor stage.Conclusions Our results show that laparoscopic right hemicolectomy for colon cancer can be performed safely. Complications and recurrence rates are comparable to those for left-sided laparoscopic and open procedures. Therefore, we recommend this procedure as the method of choice. Laparoscopically treated patients with stage II and stage III disease have almost the same cumulative rate of survival.  相似文献

INTRODUCTION

Laparoscopic colorectal surgery has gained widespread acceptance. While many studies have compared laparoscopic and open left-sided resections, there is limited literature on right colonic resections. We aimed to analyse the short-term outcome of laparoscopic (LRH) and open right hemicolectomy (ORH) in our unit.

METHODS

Consecutive patients undergoing elective right hemicolectomies over a period of 28 months were included in the study. No selection criteria were used to allocate the surgical approach. Study parameters included surgical technique, demographic details, ASA grade, body mass index (BMI), length of hospital stay (LOS), post-operative mortality and morbidity, readmission rate and histopathological data.

RESULTS

A total of 164 patients underwent right hemicolectomies during the study period (LRH: 89, ORH: 75). Both groups were comparable in age, sex, BMI, ASA grade, tumour stage and lymph node harvest. Four patients (4.5%) in the laparoscopic group required conversion to open surgery. In resections with curative intent, microscopic margins were positive in two patients (3%) in the ORH group compared to one (1%) in the LRH group. Seven ORH patients had an adverse post-operative outcome (three anastomotic leaks, four deaths); there were no deaths/immediate complications in the LRH group (p<0.05). The median LOS for LRH patients (4 days, range: 2–21 days) was significantly shorter than for ORH patients (8 days, range: 3–38 days) (p<0.0001, Mann–Whitney U test). By day 5, 77% of LRH patients were discharged compared with only 21% of patients in the ORH group. There were two readmissions (2.7%) in the ORH group and nine (10.1%) in the LRH group.

CONCLUSIONS

Our findings demonstrate advantages in favour of LRH in terms of a shorter hospital stay and reduced post-operative major complications. LRH is safe and should therefore be available to all patients requiring colonic resection.  相似文献

Aim Single‐incision laparoscopy is a rapidly evolving technique in the spectrum ‘standard laparoscopy‐natural orifice transluminal endoscopic surgery (NOTES)’. From a commercial perspective, purchase of articulating instruments is advised. However, here we present our early experience with single‐incision laparoscopy for right hemicolectomy with standard laparoscopic instrumentation. Method Between June 2010 and December 2011, 25 patients presenting with malignant disease underwent single‐incision laparoscopy for right hemicolectomy. Four different ports (SILS? port, Covidien; SSL® Access system, Ethicon; X‐Cone/S‐Portal®, Storz; and OCTO? port, AFS Medical) were used. Patients were recruited prospectively and all data were processed retrospectively. Results Twenty‐five patients were included in our study (and their characteristics, described later in this paragraph, are expressed as median (range)). Four conversions to standard laparoscopy were performed. The age of patients was 69 (36–89) years, and they had a body mass index (BMI) of 24.5 (19.1–34.2). The duration of surgery was 110 (70–148) min with a healed skin incision length of 35 (20–60) mm. Hospital stay was 5 (2–15) days. In four patients discharge was delayed because of comorbidity. One patient suffered an overwhelming pneumonia. Conclusion Single‐incision laparoscopy using standard laparoscopic instruments appears to be a safe and feasible technique for malignant disease requiring right hemicolectomy. Randomized, prospective trials are ongoing to prove the benefits of this technique and to compare its oncological outcome measures with those of conventional laparoscopy. In our experience, a low‐profile port with a wide intra‐abdominal range of motion is most preferable.  相似文献
