OBJECTIVE: An analysis was performed to evaluate early patterns of recurrence and survival in patients undergoing laparoscopic-assisted colectomies for primary colorectal cancer. Thirty-nine patients are available with a minimum of 24 months postoperative follow-up. SUMMARY BACKGROUND DATA: The techniques and expected surgical outcomes for patients undergoing laparoscopically assisted colectomies are slowly being defined as these procedures become more common and more widely available. One of the areas of greatest concern is the use of laparoscopic-assisted colectomy for the surgical treatment of patients with primary colorectal cancer. There are anecdotal reports in the literature describing both port site recurrence and wound recurrence in patients undergoing laparoscopic-assisted colectomies for colorectal cancer. This raises concerns about whether these recurrences are more common in patients undergoing laparoscopic procedures and whether overall survival is compromised. Wound recurrences and laparoscopic port site recurrences have been described with numerous other intra-abdominal tumors, but the precise incidence remains unknown. The authors reviewed data from 39 patients to determine early patterns of recurrence and overall survival. METHODS: Two-hundred thirty-eight laparoscopic-assisted colectomies were performed by the Norfolk Surgical Group between June 1992 and September 1995. Thirty-nine of the patients who underwent resection for colorectal cancer between June 1992 and September 1993 currently are available for at least a 2-year follow-up. Preoperative evaluation included physical examination, liver function studies, carcinoembryonic antigen, chest x-ray, computed tomography scans, and endoscopies with biopsy. Postoperative follow-up data consisted of physical examination, liver function tests, CEA, chest X-ray, computed tomography scan of the abdomen, and endoscopy of the colon. No patients have been lost to follow-up. Survival rates and patterns of recurrence were compared between node-negative and node-positive patients and compared with conventional data after open surgery. RESULTS: There were 22 men and 17 women ranging in age from 33 to 89 years. Mean follow-up was 30 months, with a range of 24 to 40 months. There were three patients with recurrence and nine deaths. Recurrence and tumor-related death rates, respectively, for each Dukes' stage were 0/1 and 0/1 for stage A, 0/7 and 0/7 for stage B-1, 1/16 and 2/16 for stage B-2, 0/1 and 0/1 for stage C-1, and 2/8 and 1/8 for Stage C-2. All six patients with Dukes' stage D disease died of metastatic colorectal cancer within 4 to 14 months of surgery. There were two patients with anastomotic recurrence. No unusual patterns of recurrent disease were noted, and there were no wound or port site recurrences. CONCLUSIONS: In this group of patients undergoing laparoscopic-assisted colectomies for primary colorectal malignancy, no adverse patterns of recurrence or decreased survival has been noted at 2-year follow-up when compared with standard open colorectal cancer surgery statistics. Prospective randomized studies with long-term follow-up will be required to better define the potential benefits and adverse effects of laparoscopic surgery for colorectal malignancy. 相似文献

Purpose To compare the long-term outcome of laparoscopic-assisted colectomy (LAC) with that of open colectomy (OC) for carcinoma in patients followed up for a minimum of 4 years.Methods We reviewed the medical records of 118 patients who underwent LAC between January 1993 and September 1999, and compared the results with those of 163 selected patients who underwent OC during the same period.Results Curative surgery was performed in 114 of the LAC patients. Because recurrence did not develop in any of the patients with stage I cancer, we analyzed the patterns of recurrence only in those with stage II or III disease; 58 patients were analyzed in the laparoscopic group and 130 in the open colectomy group. In the LAC group, 7 (12.1%) patients had recurrence after a median follow-up of 58 months and in the OC group, 19 (14.6%) patients had recurrence after a median follow-up of 56.5 months. The 5-year disease-free rate was similar in the LAC (87.8%) and OC (85.5%) groups (P = 0.75 by the log-rank test).Conclusions Laparoscopic-assisted colectomy is effective and safe for the treatment of colorectal carcinomas under the criteria used in this study. However, further validation of these results is recommended. 相似文献

OBJECTIVE: The authors studied the results of laparoscopic colectomies performed by a surgical team on 80 consecutive patients and compared these results with standard open colectomies. METHODS: Eight consecutive laparoscopic-assisted colectomies were performed by Norfolk Surgical Group in a 14-month period and compared to 53 patients who had a conventional open colectomies. Analysis included indications for surgery, types of procedure, complications, incidence and causes for conversion, length of procedure, duration of postoperative ileus, hospital stay, operating room and total hospital charges, and examination of the pathologic specimens. RESULTS: Many different types of colectomies were performed successfully and safely for a variety of surgical indications. The conversion rate was 22.5%, which decreased to 15% in the second half of the series. Complications in patients who underwent laparoscopic operations were not severe in number of type. The length of the operative procedure, operating room charge, and the total hospital charge were greater for patients undergoing laparoscopic-assisted colectomies. Patients who underwent laparoscopic operations had a shorter period of postoperative ileus and less pain, resumed a regular diet sooner, and were discharged from the hospital sooner than patients who underwent open colectomies. There was no significant difference in the pathology specimens obtained by laparoscopic-assisted colectomies compared with conventional open colectomies for length of specimen, surgical margins, and number of lymph nodes retrieved. CONCLUSIONS: This study indicated that laparoscopic techniques can be applied safely and effectively to a broad range of colonic operations. Laparoscopic-assisted colectomies take longer to perform and are more costly, but are associated with less paralytic ileus, less pain, and reduced hospital stay. Laparoscopic colectomies for the treatment of malignancy are achievable technically, but will require careful long-term study. 相似文献

Laparoscopic-assisted colectomy is considered to be a less invasive technique, and patients experience less pain and more rapid postoperative recovery. This operation has been indicated for large sessile adenomas or for early invasive carcinomas in Japan. The indications for this procedure in more advanced colorectal carcinomas is controversial. However, based on our experience with 130 cases, laparoscopic-assisted colectomy can be as curative as open colectomy provided that the patients are properly selected. In this review, the technical difficulties of this procedure are also discussed. 相似文献

OBJECTIVES: Laparoscopic colon and rectal surgery requires advanced laparoscopic skills. The aim of this study was to describe a novel technique for laparoscopic-assisted colectomy using only 2 ports and to review our initial experience with this technique for patients with benign colonic pathologies. METHODS: A retrospective chart review of all patients who had laparoscopic-assisted colon surgery using this technique was performed. The technique is described. RESULTS: For right colectomy, a 10-mm trocar for the camera was placed just below the umbilicus and a 5-mm working port just above the umbilicus. The colon was mobilized using one instrument and gravity assistance. The incisions were then connected, and the mobilized colon was pulled through this incision. For left-sided colectomy, the 5-mm working port was placed at the left suprapubic hairline, which was then extended for removal of the specimen. Sixty patients with benign colonic pathologies had laparoscopic-assisted colon surgery using only 2 ports. Conversion to open surgery was required in 4 cases. The average length of the skin incision was 3.82 cm, and the mean length of hospital stay was 4.18 days. Postoperative complications occurred in 11 patients (18%) and included anastomotic leak in 1 patient and wound infection in 2. CONCLUSIONS: Laparoscopic-assisted segmental colectomy using 2 ports is easy and feasible, with minimal skin incisions and fast recovery. Our initial experience suggests that it may be easier for the experienced colorectal surgeon to acquire the skills needed to perform this technique. 相似文献

Laparoscopic-assisted left colon resection entails reestablishing pneumoperitoneum and laparoscopic colorectal anastomosing, if performed through a left lower-quadrant incision. A horizontal suprapubic incision allows direct view of the colorectal anastomosis obviating the need for reestablishing pneumoperitoneum. Performing colorectal anastomoses in an open fashion via a suprapubic incision and with nonrestoration of pneumoperitoneum will contain operating time in laparoscopic-assisted left colectomy. 相似文献

Background: The success of laparoscopic cholecystectomy in providing patient benefits in the immediate postoperative period has led to laparoscopic techniques being used for many other intra-abdominal procedures. Colorectal resection for malignancy is one of the more contentious applications of this new technology, because the postoperative benefits are more subtle and the long-term oncological results are as yet unknown. Methods: A review of the English-language literature was undertaken in order to collate and analyse all published series where 20 or more laparoscopic colectomies were performed, and where the indication for resection in the majority of cases was adenocarcinoma of the colon. Results: Laparoscopic colectomy for cancer can be performed safely by experienced surgeons, although there is a considerable learning curve for the procedure. The expected benefits of minimal access surgery are provided by laparoscopic colectomy, although to a lesser extent than that seen with other procedures. The oncological safety of the procedure is as yet unproven. It is clear that an equivalent resection can be performed, but not whether this translates to an equivalent recurrence and survival rate. Reports of isolated port-site recurrences are of concern. Conclusions: Early results of laparoscopic colectomy for cancer are encouraging, although the fate of this procedure rests with the analysis of the large multicentre prospective randomized trials currently under way, particularly with regard to the long-term recurrence and survival rates. 相似文献

Background: This study was performed to prospectively assess the impact of the laparoscopic approach to the patterns of port site metastases (PSM) and recurrence rate (RR) of resected colon carcinomas as compared with conventional colectomies. Methods: All patients were included in a prospective randomized trial comparing laparoscopic-assisted colectomy (LAC) versus open colectomy (OC) for colon cancer. The randomization was stratified for localization of the lesion. Patients with metastasic disease at the time of the surgery were excluded. Follow-up in the outpatient clinic was done every 3 months for a minimum of 12 months. Endpoints for the study were metastasis at port site and laparotomy incision as well as recurrence rate. Results: Of 91 segmental colectomies performed from November 1993 to January 1996, there were 44 LAC and 47 OC. Patient data were similar in both groups (age, sex, Dukes stage, type of operation). Mean follow-up was 21.4 months, with a range of 13 to 41 months. There were no wounds or PSM in those series. RR was similar for both groups. For LAC, it was five of 31 (16.1%); for OC, it was six of 40 (15%). Conclusions: The laparoscopic approach has a recurrence rate similar to that for open procedures for colon cancer. However, additional follow-up of these patients is needed before we can determine whether or not the laparoscopic approach influences overall survival. 相似文献

Laparoscopic-assisted vs open colectomy for severe acute colitis in patients with inflammatory bowel disease (IBD) 总被引:2,自引:0,他引:2
Dunker MS Bemelman WA Slors JF van Hogezand RA Ringers J Gouma DJ 《Surgical endoscopy》2000,14(10):911-914
BACKGROUND: Inflammatory bowel disease (IBD) can be complicated by severe acute colitis. Emergency colectomy is mandatory if patients do not respond to intensive medical therapy. A minimally invasive approach such as laparoscopic-assisted colectomy might be beneficial in these patients. Therefore, we set out to assess the feasibility and the safety of emergency laparoscopic-assisted colectomy in IBD patients with severe acute colitis. METHODS: A total of 42 consecutive patients underwent an emergency colectomy with end-ileostomy. Ten patients had laparoscopic-assisted colectomy, and 32 had open colectomy. Pre- and perioperative parameters, morbidity, and mortality were analyzed. RESULTS: The two groups were comparable for patient characteristics. There were no conversions in the laparoscopic group. The operation time was longer in the laparoscopic group than in the open group (271 vs 150 min; p < 0.001), but the hospital stay was shorter (14.6 vs 18.0 days; p = 0.05). Complications were similar for the two groups. CONCLUSION: Laparoscopic-assisted colectomy in IBD patients with severe acute colitis is feasible and as safe as open colectomy. 相似文献

In recent years, laparoscopic surgery has become a matter of growing interest. It has been shown that laparoscopic colectomy is well tolerated and safe for benign disease. However, there is some uncertainty about using this method for malignant disease when curative resection is the aim. These uncertainties mainly consist of spread of cancer to port site, long-term survival, and adequacy of resection. The majority of laparoscopic colectomies are technically assisted procedures in which anastomosis is performed outside the abdomen. However, some surgeons are now performing this surgery totally laparoscopically with the anastomosis performed inside the abdomen. Laparoscopic colectomy is currently practiced with great frequency by general surgeons. Its performance requires a steep learning curve and a large number of cases to obtain proficiency. The indications for laparoscopic colectomy are different from one institution to another. In some institutions all patients with colorectal disease are candidates for laparoscopic colectomy and in others it may be limited to benign disease only. The purpose of this review is to analyze all laparoscopic colectomies performed at our medical center since 1992. We conducted a retrospective chart review of both hospital and clinic charts of patients who underwent colectomies at our hospital. A total of 338 patient charts were reviewed. In a comparison of both laparoscopic (n = 285) and converted (n = 53) methods, the age and operative time were about the same. Age average and operating room time average were similar for both groups. With laparoscopy, there was a 3-day drop in length of hospital stay as well as a 1-day-earlier regaining of bowel function. Hospital cost dropped 5000 dollars average for the laparoscopic colectomy. The conversion rate at our center was 15 per cent. Complication rates were lower in the laparoscopic group. Recurrence of cancer at the port site (0.7%) was no higher than in the converted group (incisional recurrence, 1.8%). We conclude that laparoscopic colectomy does show an improvement in return of bowel function, hospital cost, and shorter hospital stay. Long-term follow-up will be necessary to determine the effectiveness of laparoscopic colon resection for colorectal cancer. 相似文献

The role of laparoscopic resection in the management of colorectal cancer is still unclear. It has been shown that laparoscopic colectomies can be accomplished with acceptable morbidity. Major concerns are port-site recurrences and neoplastic dissemination. The aims of this study were to compare perioperative results and long-term outcomes in a prospective, nonrandomized study of patients treated by laparoscopic versus open colorectal resection for cancer. In particular, the effects of an initial laparoscopic approach on survival and recurrence were examined. One hundred fifty-seven patients with colorectal carcinoma were included in the prospective trial: 74 underwent laparoscopic resection and 83 underwent conventional open surgery. The two groups were comparable in terms of characteristics, demographic data, stage of disease, and use of adjuvant or palliative chemoradiotherapy. All patients were observed at 1.3- and 6-month intervals. The median duration of follow-up was 60 months (range, 10-125 months). The mean operating time was significantly longer in the laparoscopic group. Six conversions (8.1%) were necessary. The passage of flatus and the restarting of oral intake (P = 0.0001) occurred earlier in the laparoscopic surgery group than in the open conventional surgery group. The mean postoperative stay was significantly shorter in the former group (P = 0.005), as was the length of the scar (P = 0.001). There were no deaths in either group. The overall morbidity was significantly lower (13% versus 33.7%; P = 0.001) in patients treated laparoscopically. No significant differences were observed between the groups in the length of specimens, the size of the tumor, or the number of nodes removed. Late complications were more frequent after open resection (12% versus 5.4%; P = 0.01). Two port-site metastases (2.6%) were seen in stage III and IV locally advanced carcinoma. There was no significant difference in recurrent disease between the groups (24.3% versus 25%) during the 60-month follow-up. Stage-for-stage comparisons showed that disease recurrence rates and crude death rates were comparable. 相似文献

OBJECTIVE: The authors described their experience with laparoscopic-assisted colorectal resection for colorectal carcinoma, both curative and palliative, with emphasis on patient selection. The techniques of the operations were described. SUMMARY BACKGROUND DATA: Laparoscopic colorectal procedures for treatment of benign lesions have been shown to be less painful and to enhance early postoperative recovery. However, use of laparoscopic procedures for treatment of colorectal cancer are controversial. The authors have used laparoscopic techniques for curative and palliative resections of colorectal carcinoma with satisfactory early results. METHODS: One hundred patients with colorectal carcinoma were selected over a 30-month period for laparoscopic-assisted colorectal resection. For 17 patients, laparoscopy revealed bulky tumor or locally advanced disease, and open surgery was performed. For 83 patients, laparoscopic-assisted colon and rectal resections were attempted. Procedural data and postoperative results were entered prospectively. The median follow-up period was 15.2 months (range, 2.5-32.7 months). RESULTS: Fourteen of 83 patients eventually required conversion to open surgery. The median operative time was 180 minutes. The patients could return to a normal diet in a median of 4 days. The median number of doses of analgesics required was two, and the median hospital stay was 6 days. The morbidity rate was 12%, and there was no deaths attributable to the procedure. There were four distant recurrences and one pelvic recurrence. CONCLUSIONS: Laparoscopic-assisted colorectal resection for selected patients is feasible, and early postoperative results are encouraging. This procedure does not appear to be associated with an excessive recurrence rate, and long-term follow-up is necessary for late survival figures. 相似文献

Background
There are few studies that compare the incidence of incisional hernia following elective laparoscopic colon resection to open colectomy and determine the risk factors for its development.Methods
Elective open and laparoscopic colon resections performed between February 2002 and May 2007 were reviewed. In the laparoscopic group, mesenteric transection was performed via intracorporeal division for left-sided colectomy and via extracorporeal technique for right-sided colectomy. The ileocolic anastomosis was performed by extracorporeal stapling for right colectomies and by intracorporeal for left colectomies.Results
Two hundred eighteen patients (mean age 62 years, 52% male) underwent elective colon resection (50% open, 5% hand-assisted, and 45% laparoscopic). Six percent of the cases that started as laparoscopic were converted and are included in the open group. Mean follow-up was 26 months. The overall incisional hernia rate was 16% (open and minimally invasive group 17% vs 15%, P = .14). Hernia was not dependent on the type of resection, indication, or extraction site. Body mass index >36 kg/m2, male gender, and surgical site infection were risk factors for hernia development.Conclusions
Laparoscopic colectomy does not reduce the development of incisional hernia. 相似文献15.
Background The role of laparoscopic surgery for malignant gallbladder tumors remains uncertain. This study compared the surgical results
of laparoscopic versus conventional open cholecystectomy for patients with early-stage gallbladder carcinoma and examined
the role of laparoscopic surgery for early gallbladder carcinomas.
Methods Data for the treatment of gallbladder carcinomas were gathered from Chang Gung Memorial Hospital (Linkou, Taiwan). A retrospective
analysis of 40 patients with either stage 0 or stage 1 gallbladder carcinoma was performed. The patients were categorized
into two groups on the basis of cholecystectomy procedures. The long-term outcomes for the two groups were compared.
Results During the follow-up period, which ranged from 6.5 to 197.6 months, four patients in the conventional open cholecystectomy
group encountered tumor recurrence, and one patient in the laparoscopic cholecystectomy group experienced distant tumor recurrence
(p = 0.216). No local port-site tumor recurrence was identified in patients who underwent laparoscopic cholecystectomy. The
overall 5-year survival rate in this series was 87.1%. A comparison of survival rates between the two groups demonstrated
no significant difference (p = 0.340).
Conclusion The laparoscopic cholecystectomy procedure did not adversely influence the prognosis of patients with early-stage gallbladder
carcinomas. Furthermore, meticulous removal of gallbladders during laparoscopic surgery, in which early gallbladder carcinoma
can be managed successfully using laparoscopic cholecystectomy, achieved a satisfactory surgical result and a low port-site
tumor recurrence rate. 相似文献

Laparoscopic-assisted colectomy with lymph node dissection for invasive carcinoma of the colon 总被引:2,自引:0,他引:2

The results of performing laparoscopic-assisted colectomy in 20 patients with invasive carcinoma of the colon were analyzed in this study. The site of the lesion was the right colon in 5 patients, the transverse colon in 1, the left colon in 13, and the rectosigmoid in 1. In 2 patients, the laparoscopic procedure needed to be converted to an open laparotomy. Limited lymph node dissection (R1+, R2) was carried out in 10 patients and extensive node dissection (R3) was carried out in 9 patients. The histological depth of invasion in the 18 patients who underwent laparoscopic-assisted colectomy was the submucosa in 9, the muscularis propria in 2, and the extramuscular layer in 7. There were 3 patients who developed postoperative complications, 1 of whom underwent reoperation due to perforation of the colon. The postoperative course of the patients who underwent laparoscopic surgery was compared with that of a retrospectively selected control group of patients who had undergone open laparotomy. The postoperative recovery of the patients who underwent laparoscopic surgery was significantly faster than that of those who had undergone open laparotomy. Thus, we consider that laparoscopic-assisted colectomy with lymph node dissection is technically feasible provided that patients are properly selected. This procedure may be indicated not only for colonic carcinoma in the early stage, but also for that with invasion of the muscularis propria or the extramuscular layer. 相似文献

BACKGROUND: Laparoscopic techniques are currently used for curative resection of colorectal cancer although long-term results from controlled clinical trials are not available yet that prove laparoscopic procedures are adequate. METHODS: All patients who under-went a curative resection of a colorectal tumor from 1995 to 1997 were included in a prospective cohort study to evaluate the short- and long-term results. RESULTS: Laparoscopic colorectal resections were accomplished in 68 patients. In only 3 patients was an adenoma (stage 0) found, and 10 patients had multiple liver metastases at the time of palliative resection. An oncological resection was performed in 55 patients. The average age was 62.8 +/- 14.6 years (29 female and 26 male patients). Eleven right colectomies, 1 left colectomy, 21 sigmoid resections, 16 proctosigmoidectomies and 6 abdominoperineal resections were carried out. Two patients (3.6%) were lost during follow-up. The median follow-up was 27.1 months (range 9.1-45.1 months). No port-site metastases were found. Two patients who are still alive after sigmoid resection suffered from a recurrence. The first patient underwent only limited lymphadenectomy because of synchronous malignant lymphoma. The second patient developed bilateral lung metastases. Only one patient died during the follow-up period because of myocardial infarction. CONCLUSION: Although the follow-up is short, it seems that the recurrence rate is low. Controlled multicenter clinical trials are currently performed to evaluate whether laparoscopic surgery is really adequate to treat colorectal cancer. 相似文献

Laparoscopic colectomy for colon adenocarcinoma: an 11-year retrospective review with 5-year survival rates 总被引:2,自引:0,他引:2
Background Laparoscopic colectomy for the management of colon cancer remains a controversial therapeutic option, especially when the outcomes are compared with the historically accepted survival data and recurrence rates after open surgery. The purpose of this study was to evaluate the 5-year overall and disease-free survival rates after laparoscopic colon resection for invasive colon adenocarcinoma.Methods A total of 129 patients underwent consecutive laparoscopic colectomies for colon adenocarcinoma (between April 1992 and 2004 January) by a single surgeon at a single institution. Records were analyzed retrospectively and follow-up data was obtained. The Student t-test, Cox regression analysis, and Kaplan-Meier survival data were used for statistical analysis.Results After patients with noninvasive disease on final pathology were excluded, the study population comprised 88 patients who underwent laparoscopic colectomies for invasive colon cancer with > 2 years of follow-up. Of these cases, 81 (93%) were amenable for complete follow-up at 11years (41 women and 40 men; mean age, 76 years). Mean follow-up was 61 months. There was one perioperative death (1.2%), and the overall postoperative morbidity rate was 13.6%. The average number of lymph nodes harvested was 10.1 (±6). There were no port site recurrences. The Kaplan-Meier survival data were as follows for 5-year overall survival and 5-year disease-free survival, respectively stage I (n = 34) 89% and 89%; stage II (n = 22), 65% and 59%; stage III (n = 19), 72% and 67%; stages I–III combined, (n = 75), 77% and 73%.Conclusions For this specific cohort of patients undergoing curative laparoscopic colectomies for invasive colon adenocarcinoma, the mean follow-up was > 5 years. Overall survival and disease-free survival for stage I, II, and III colon cancer as well as for stages I–III combined are favorable and comparable to historically acceptable open colectomy survival rates. Overall survival and disease-free survival after laparoscopic colectomy for invasive colon cancer is no worse, and perhaps better than, the previously reported rates for the same procedure done by an open technique. 相似文献

Short-term outcome analysis of a randomized study comparing laparoscopic vs open colectomy for colon cancer 总被引:19,自引:6,他引:13
A. M. Lacy J. C. García-Valdecasas J. M. Piqué S. Delgado E. Campo J. M. Bordas P. Taurá L. Grande J. Fuster J. L. Pacheco J. Visa 《Surgical endoscopy》1995,9(10):1101-1105
The authors examined the impact of the laparoscopic approach on the early outcome of resected colon carcinomas. The role of laparoscopic techniques in the treatment of colon carcinomas is questionable. Previous studies have suggested technical feasibility of surgical resections of these cancers by laparoscopic means and have implied a benefit to laparoscopic technique for patients undergoing colorectal resections. A prospective, randomized study was conducted comparing laparoscopic assisted colectomy (LAC) open colectomy (OC) for colon cancer. We present the preliminary results in relation to the short-term outcome and judge the feasibility of the laparoscopic procedure to as a way of performing accurate oncologic resection and staging. Benefit has been demonstrated with LAC in this setting. Passing flatus, oral intake, and discharge from hospital occurred earlier in LAC- than OC-treated patients The mean operative time was significantly longer in the LAC group than in the OC group. The overall morbidity was significantly lower in the LAC group. No significant differences were observed between both groups in the number of lymph nodes removed or the pathological stage following the Astler-Coller modification of the Dukes classification. The laparoscopic approach improves the short-term outcome of segmental colectomies for colon cancer. However, the further follow-up of these patients will allow us to answer in the near future whether or not the LAC may influence the long-term outcome.Presented at the annual meeting of the Society of American Gastrointestinal Surgeons (SAGES), Orlando, FL, USA, 11–14 March 1995 相似文献

Background Evidence of benefits of laparoscopic and laparoscopic-assisted colectomies (LAC) over open procedures in gastrointestinal
surgery has continued to accumulate. With its wide implementation, technical difficulties and limitations of LAC have become
clear. Hand-assisted laparoscopic surgery (HALS) was introduced in an attempt to facilitate the transition from open techniques
to minimally invasive procedures. Continuing debate exists about which approach is to be preferred, HALS or LAC. Several studies
have compared these two techniques in colorectal surgery, but no single study provided evidence which procedure is superior.
Therefore, a systematic review was carried out comparing HALS with LAC colorectal resection.
Methods Eligible studies were identified from electronic databases (Medline, Embase Cochrane) and cross-reference search. The database
search, quality assessment, and data extraction were independently performed by two reviewers. Minimal outcome criteria for
inclusion were operating time, conversion rate, hospital stay, and morbidity.
Results Out of 468 studies a total of 13 studies were selected for comprehensive review. Two randomized controlled trials (RCT) and
11 non-RCTs, comprising 1017 patients, met the inclusion criteria. Because of possible clinical heterogeneity two groups of
procedures were created: segmental colectomies and total (procto)colectomies. In the segmental colectomy group significant
differences in favor of the HALS group were seen in operating time (WMD 19 min) and conversion rate (OR of 0.3 conversions).
In the total (procto)colectomy group a significant difference in favor of the HALS group was seen in operating time (WMD 61 min).
Conclusions This systematic review indicates that HALS provides a more efficient segmental colectomy regarding operating time and conversion
rate, particularly accounting for diverticulitis. A significant operating time advantage exists for HALS total (procto)colectomy.
HALS must therefore be considered a valuable addition to the laparoscopic armamentarium to avoid conversion and speed up complicated
colectomies. 相似文献
