Comparative results of surgical management of single carcinomas of the colon and rectum: a series of 1939 patients managed by one surgeon

A comparative analysis has been made of the results of surgical management of single carcinomas of the colon and rectum in a series of 1939 patients treated by one surgeon. The data were prospectively collected, with 99 per cent follow-up. Cancer specific survival did not differ significantly between patients with colonic or rectal cancer. Survival prospects were better for women (P = 0.02) and for patients less than 40 years of age (P = 0.03). Survival was significantly related to tumour staging (P less than 0.002). Cancer specific survival was better after curative resection for colonic than rectal carcinoma (P = 0.003). Five-year survival for patients with colonic tumours was 76 per cent and for rectal tumours 69 per cent. The 10-year survival figures were 73 per cent and 51 per cent respectively. This difference was accounted for by a higher proportion of Dukes' stage C tumours in the rectum (P less than 0.001) and better survival prospects for colonic compared to rectal stage C1 tumours (P = 0.02). Sphincter-saving resections were performed in 64 per cent of rectal cancer patients managed by curative resection. Survival tended to be better than after sphincter-sacrificing operations. After palliative resection, median survival for colonic and rectal cancer was 14 and 13 months respectively. After palliative bypass operations the corresponding figures were 4 and 8 months.     

Impact of surgeon volume and specialization on short-term outcomes in colorectal cancer surgery

BACKGROUND: Several studies have shown a relationship between surgeon volume and outcomes in colorectal cancer surgery. The aim of this study was to determine the impact of surgeon volume and specialization on primary tumour resection rate, restoration of bowel continuity following rectal cancer resection, anastomotic leakage and perioperative mortality. METHODS: The Northern Region Colorectal Cancer Audit Group conducts a population-based audit of patients with colorectal cancer managed by surgeons. This study examined 8219 patients treated between 1998 and 2002. Outcomes were modelled using multivariate logistic regression analysis. RESULTS: Tumour resection was performed in 6949 (93.8 per cent) of 7411 patients. High-volume surgeons with an annual caseload of at least 18.5 (odds ratio (OR) 1.53 (95 per cent confidence interval (c.i.) 1.10 to 2.12); P = 0.012) and colorectal specialists (OR 1.42 (95 per cent c.i. 1.06 to 1.90); P = 0.018) were more likely to perform elective sphincter-saving rectal surgery. In elective surgery, the risk of perioperative death was lower for high-volume surgeons (OR 0.58 (95 per cent c.i. 0.44 to 0.76); P < 0.001), but this was not the case in emergency surgery. CONCLUSION: High-volume surgeons had lower perioperative mortality rates for elective surgery, and were more likely to use restorative rectal procedures.     

Outcome of colorectal cancer

The outcome of 454 patients who presented with colorectal carcinoma during a 16 year period is reviewed: 54 per cent were males, 58 per cent were aged more than 60 and 10 per cent had an emergency admission, 42 per cent of tumours occurred in the rectum. A curative resection was possible in 68 per cent. Postoperative mortality was 7 per cent. The overall crude 5-year survival was 41 per cent. The mortality from local recurrence was significantly higher in rectal (11.7 per cent) than in colonic cancer (8.8 per cent; P less than 0.01). The rate of recurrence and metastases was higher in patients with low rectal cancer than in patients with cancer of the middle and the upper rectum (P less than 0.01). Distant metastases were the cause of death in 94 per cent of the patients who had a Miles' operation for cancer of the middle rectum, whereas local recurrence was responsible for late mortality in 80 per cent of patients who underwent an anterior resection. No difference in 5-year survival was found in the restorative and in the excisional group.     

Changing attitudes toward management of cancer of the colon and rectum

Changes in the attitudes of surgeons toward the management of cancer of the colon and rectum over a 5-year period were assessed by analysis of responses of general surgeons to a 21-item questionnaire on colon cancer from 1978 and 1983. Comparisons of the responses revealed that the use of routine preoperative liver scans has decreased from 57 to 45 per cent. Transanal resection of villous adenoma of the rectum is used more often (44% in 1983 versus 34% in 1978). For obstructing carcinoma of the colon, a two-stage procedure is used more often, with 46 per cent of the respondents in favor of this approach in 1983 compared with 29 per cent in 1978. The use of staplers for colon anastomoses following resection has also increased with 44 per cent surgeons in 1983 using this technique always or frequently compared with 21 per cent in 1978. Following anterior resection, 66 per cent of respondents in 1983 seldom or never use a transverse colostomy (54% in 1978). The number of surgeons closing the perineal wound over suction drains following an abdominoperineal resection has increased from 46 per cent (1978) to 63 per cent in 1983. Sphincter-saving procedures for carcinoma of the rectum are used by a large number of surgeons in 1983 (29% versus 9% in 1978). An increase is noted in the use of preoperative radiation therapy for selected cases of rectal cancer (53% in 1978 to 68% in 1983).(ABSTRACT TRUNCATED AT 250 WORDS)     

T4 rectal cancer: analysis of patient outcome after surgical excision

Locally advanced rectal cancer dictates a major surgical undertaking, which includes en bloc resection of the rectum and all involved organs. The aim of this study was to evaluate patient outcome and compare multimodality treatment options after various surgical approaches from one institution for T4 rectal cancer. A retrospective chart review identified 24 patients who were operated on for advanced primary rectal cancer invading adjacent structures (T4) over a 5(1/2)-year period. The types of treatment and outcome were analyzed. From these 24 patients, the most frequently involved organ was the bladder (33%). A total of 16 patients underwent chemoradiotherapy. There were 12 complications (50%), the most common being wound infection (33% of complications, 17% overall). Nine patients had nodal disease. Disease-free survival was 54 per cent, and overall survival was 75 per cent. However, disease-free survival in node-negative patients was 67 per cent versus 33 per cent in node-positive individuals. Out of the six patients who died in this review, five (83%) received chemoradiotherapy. Operations for advanced primary rectal cancer with involvement of adjacent organs are major procedures associated with high morbidity. Patients without nodal disease may have long-term survival despite the locally advanced tumor. Interestingly, neoadjuvant therapy, adjuvant, or both, did not increase survival.     

Survival benefit of high ligation of the inferior mesenteric artery in sigmoid colon or rectal cancer surgery

BACKGROUND: The aim of this study was to assess the impact of inferior mesenteric artery (IMA) root nodal dissection before high ligation of the artery on survival in patients with sigmoid colon or rectal cancer. METHODS: Data on 1188 consecutive patients who underwent resection for sigmoid colon or rectal cancer, with high ligation of the IMA, were identified from a prospective database (April 1965 to December 1999). Survival of patients with involvement of nodes along the IMA proximal to the origin of the left colic artery (root nodes, station 253) through the bifurcation of the superior rectal artery (trunk nodes, station 252) was determined. RESULTS: Twenty patients (1.7 per cent) had metastatic involvement of station 253 lymph nodes and 99 (8.3 per cent) had metastases to station 252. The 5- and 10-year survival rates of patients with metastases to station 253 were 40 and 21 per cent, and those for patients with metastases to station 252 were 50 and 35 per cent, respectively. CONCLUSION: High ligation of the IMA allows curative resection and long-term survival in patients with cancer of the sigmoid colon or rectum and nodal metastases at the origin of the IMA.     

Improving survival rates for patients with colorectal cancer.

Between 1 January 1984 and 31 December 1990, 575 patients were operated on for colorectal cancer. The surgical procedure was performed consistently and no patients were lost to follow-up. Almost half of the patients (284 of 575) had tumours of stage I or II, with 5-year survival rates over 90 per cent. After extending the resection margins in 28 cases of colonic carcinoma there has been no case of tumour recurrence. The overall 5-year survival rate for patients with colonic carcinoma was 81 per cent. Complete resection of the mesorectum was mandatory for rectal resection. One-third of the carcinomas in the lower third of the rectum could be resected with maintenance of bowel continuity and an abdominoperineal resection avoided. Not only was the tumour recurrence rate in the former patients lower (10.5 per cent) compared with that in those undergoing abdominoperineal resection (14.3 per cent) but the 5-year survival rate at 90 versus 52 per cent was significantly higher. The overall 5-year survival rate for patients with rectal carcinoma was 71 per cent.     

Locoregional recurrence (non hepatic abdominal recurrence) of rectal cancer

Thirty percent of deaths are related to locoreional recurrence. All patients with nonhepatic abdominal recurrence (NHAR) were considered as having locoregional failure. The aims of this study are firstly to retrospectively evaluate the results of potentially curative resection and palliative treatment modalities for a group of 25 patients with NHAR from rectal cancer. The second aim is to determine the effectiveness of R1 resection in these patients in terms of survival. In this study we have followed 25 patients with NHAR of which 10 were able to undergo potentially curative salvage resection, whilst the remaining 15 had either a palliative (R2) or no resection. The goals of treatment for recurrent rectal cancer are palliation of symptoms, a good quality of life, and if possible, cure with a low rate of treatment--related complications. Indications for salvage surgery depend on several factors including the extent of disease, the presence of concomitant illness and the surgeons experience. Systemic disease, systemic disease with peritoneal implants, multiple hepatic metastases, or extensive pelvic involvement preclude surgical treatment for cure. Curative and noncurative surgical procedures were performed width acceptable complications in the series presented hereThe mean survival for the group undergoing R0 resection was 50 months versus 55 months for the group undergoing R1 resection (not significant). Mean survival were 7,3 and 6 months in the groups undergoing R2, NR and NS respectively. The 5-year survival for the 10 patients who had potentially curative resection was 30 per cent versus 0 per cent for 15 patients who had non-curative procedures (p = 0.001). There was 1 post-operative 30 day mortality in the series of 19 patients who underwent surgery. Five patients (6 per cent) developed one or more post-operative complications. Two of them required reoperation.     

Impact of total mesorectal excision on the results of surgery of distal rectal cancer.

BACKGROUND: This study reviewed the results of surgery for distal rectal cancer (tumours within 6 cm of the anal verge) following the introduction of total mesorectal excision for rectal cancer in one institution. METHODS: Two hundred and five patients who had undergone surgical resection of rectal cancer within 6 cm of the anal verge were included. The demographic, operative and follow-up data were collected prospectively. Comparisons were made between patients who had different surgical procedures. RESULTS: Abdominoperineal resection (APR) was performed in 27.8 per cent of patients, falling from 36.0 per cent in the first 3 years to 20.0 per cent in the last 3 years of the study. The overall operative mortality rate was 1.5 per cent and the morbidity rate 30.2 per cent. With a mean follow-up of 36 months, local recurrence occurred in 28 of the 185 patients who had curative resection. The 5-year actuarial local recurrence rates for double-stapled anastomosis, peranal coloanal anastomosis and APR were 11.2, 34.6 and 23.5 per cent respectively. The local recurrence rate was significantly lower for double-stapled low anterior resection than for the other types of operation. The overall 5-year survival rate in patients with low anterior resection and APR was 69.1 and 51.1 per cent respectively (P = 0.12). CONCLUSION: With the practice of total mesorectal excision, APR was necessary in only 27.8 per cent of patients with rectal cancer within 6 cm of the anal verge. The local recurrence rate was much lower in patients with double-stapled low anterior resection than in those treated with APR or peranal anastomosis.     

The surgeon as a prognostic factor after the introduction of total mesorectal excision in the treatment of rectal cancer

BACKGROUND: With conventional blunt surgical resection of rectal cancer, local recurrence rates are high and the individual surgeon putatively influences patient outcome. With total mesorectal excision (TME) local recurrence rates have been reduced and intersurgeon variability may be less important. The 'TME project' was a collaborative project that included surgical workshops in Stockholm between 1994 and 1997. The aim of this study was to assess the impact of the project on the practice of rectal cancer surgery in Stockholm and to analyse whether surgeon case volume and participation in the workshops influenced patient outcome. METHODS: All 652 patients who had an abdominal resection for rectal cancer in Stockholm between 1995 and 1997 were included. Outcome was compared in patients operated on by teams that included high-volume surgeons (more than 12 operations per year) with teams that included low-volume surgeons (12 operations or fewer per year), as well as between teams that including workshop participants and non-participants. RESULTS: Forty-six surgeons operated on the 652 patients. Five high-volume surgeons operated on 48 per cent of the patients. In these, outcome was significantly better than in patients treated by low-volume surgeons (local recurrence rate 4 versus 10 per cent (P = 0.02); rate of rectal cancer death 11 versus 18 per cent (P = 0.007)). Twenty-six surgeons were workshop participants and performed 93 per cent of the operations. Radiotherapy, TME and sphincter-preserving surgery were more common among patients treated by workshop participants. CONCLUSION: The TME project has had an impact on rectal cancer surgical practice in Stockholm. Variability in patient outcome was mainly related to case volume, with better results obtained in patients treated by high-volume surgeons.

??Indication and objective evaluation of combined organ resection for locally recurrent rectal cancer WANG Xi-shan. Department of Colorectal Surgery, Harbin Medical University Harbin Cancer Hospital, Harbin 150080, China
Abstract Although the five-year survival rate of patients with colorectal cancer has improved, there are still 33% of patients performed radical resection of rectal cancer who will face the threat of local recurrence. The treatment of the patients presented to oncology doctors great challenges. The surgical treatment of combined organ resection is still the main treatment method to improve five-year survival rate. R0 resection is the most powerful prognostic factor. Abdomen-sacral combined organ resection with exorbitant complication incidence and mortality rate and no significant prolongation of survival has been abandoned by many surgeons. Preoperative and intraoperative chemoradiotherapy combined with surgery in the multidisciplinary treatment could improve R0 resection of locally recurrent rectal cancer.     

Utilization of laparoscopy in colorectal surgery for cancer at academic medical centers: does site of surgery affect rate of laparoscopy?

Use of laparoscopy in colorectal cancer surgery is still limited. The aim of this study was to determine the rate of use of laparoscopic colorectal surgery for cancer at academic medical centers and to evaluate if the site of surgery influences the rate of use. Clinical data of patients who underwent laparoscopic or open colon and rectal resections for cancer from 2007 to 2009 were obtained from the University HealthSystem Consortium database. Data concerning rate of laparoscopy, length of stay, morbidity, and risk-adjusted mortality were obtained. During the 36-month study period, 22,780 operations were performed. The overall rate for use of laparoscopy was 14.8 per cent. Laparoscopy was most often used for total colectomy (22.6%), sigmoid colectomy (17.3%), cecectomy (17.1%), and right hemicolectomy (17.0%). Laparoscopy was most infrequently used for abdominoperineal resection (8.0%), transverse colectomy (10.0%), and left hemicolectomy (13.1%). Length of stay for laparoscopic colon and rectal procedures was 3.2 days shorter than for open surgery. Although the benefits of laparoscopic colorectal surgery for cancer have been demonstrated, the use of laparoscopy for colorectal resection remains under 20 per cent for colon cancer and under 10 per cent for rectal cancer. Further studies are needed to determine the factors limiting the use of laparoscopy in colorectal surgery.     

Rates of colon and rectal cancers are increasing in young adults

Incidence rates for colorectal cancer are decreasing in the United States, possibly due to preventative cancer screening. Because these programs target older patients, their beneficial effects may not apply to young patients. The purpose of this study was to compare incidence rates and tumor characteristics of colon and rectal cancers for young versus older patients using a population-based cancer registry. Colon and rectal cancer patients reported in the Surveillance, Epidemiology, and End Results registry (1973-1999) were separately analyzed. Incidence rates over time, stage, and grade were compared for two age groups: young patients (20-40 years, n = 5383) and older patients (60+ years, n = 256,401). For older patients, colon cancer incidence remained stable while rectal cancer incidence decreased 11 per cent to 72.1/100,000 persons (P < 0.05). For the young, colon cancer incidence increased 17 per cent to 2.1 (P < 0.05), and rectal incidence rose 75 per cent to 1.4 (P < 0.05). Young patients had less localized tumors than older patients: colon (25.8% vs. 35.3%, P < 0.001); rectal (38.4% vs. 41.7%, P = 0.005). Young patients also had more poorly differentiated tumors: colon (22.2% vs. 14.7%, P < 0.001); rectal (16.4% vs. 12.3%, P < 0.001). Incidence rates for colon and rectal cancers in young patients are rising, and they have more advanced disease. Although the overall prevalence is low in this population, the increasing incidence suggests health-care providers should have heightened awareness when caring for this population.     

Increasing incidence of right-sided lesions in colorectal cancer.

One hundred ninety-eight patients with 211 cancers of the colon and rectum underwent elective resection at the University of Vermont College of Medicine during the five year period 1971 through 1975. Analysis of this series demonstrated that 35 per cent of all cancers were located in the cecum and ascending colon, that a similar percentage were classified as Dukes' A cancers, that a synchronous cancer was present in 5.5 per cent of the patients and that diagnosis by rectal examination and sigmoidscopy was possible in only 32 per cent of the patients. Comparison of these results with published data during the past thirty years indicate that there is an increasing incidence of carcinoma of the right colon with an associated decrease in the incidence of carcinoma of the sigmoid colon and rectum. It is recommended that patients be screened by examination of the stool for occult blood rather than by rectal examination and sigmoidoscopy so that these proximal lesions can be diagnosed at an earlier stage. Preoperative evaluation of patients with distal colorectal cancer should include double contrast barium enema examinations and colonscopy to rule out synchronous right-sided lesions.     

Obstructing carcinomas of the colon

A series of 908 cases of colonic carcinoma has been analysed to elucidate reasons for the poor prognosis in obstructing colonic cancer. Complete obstruction was present in 148 cases (16.3 per cent), 280 cases (30.8 per cent) had partial obstruction and 480 (52.8 per cent) presented without obstruction. There were fewer Dukes' A tumours in those with complete obstruction (P less than 0.005) and greater numbers of advanced tumours (P less than 0.0005) compared with those without obstruction. This is reflected in a lower curative resection rate of 50.7 per cent in those with obstruction compared with 70.6 per cent in those without obstruction (P less than 0.001). However, after curative resection there was no significant difference in the distribution of tumour stage. Patients with complete obstruction showed a higher incidence of recurrence (P less than 0.01) after curative resection, consequent to an increased incidence of local recurrence (P less than 0.02). Five-year cancer-specific survival for the total series was decreased from 59.1 per cent in patients without obstruction to 31.8 per cent in those with complete obstruction (P less than 0.001). After curative resection there was also a significant reduction in survival (P less than 0.001). It is concluded that completely obstructing colonic cancers are more aggressive than other colonic cancers.     

Krukenberg tumours of colorectal origin: Experience of a tertiary referral centre and review of the literature

Aim: Krukenberg tumours are tumours of the gastrointestinal tract that metastasize to the ovary. The condition is uncommon and accounts for 5 per cent of ovarian tumours. It is our objective to describe the outcome of patients after resection of Krukenberg tumours of colorectal origin. Patients and Methods: The present study is a retrospective review of 20 patients with resection performed for Krukenberg tumours of colorectal origin from November 1996 to April 2010 at Queen Elizabeth Hospital, Hong Kong, China. Results: The most common colonic primary site was sigmoid colon (40 per cent). Thirteen patients (65 per cent) had T4 tumours. Ten patients (50 per cent) had synchronous tumours. Seven patients (35 per cent) had bilateral ovarian involvement. Nine patients (45 per cent) had elevated serum carcinoembryonic antigen levels. The median carbohydrate antigen 125 (was 57 U/mL (range: 12–850 U/mL). Seven patients (35 per cent) developed metastases after ovarian resection. The most common sites were intra‐abdominal lymph nodes (15 per cent), bone (15 per cent) and liver (10 per cent). The overall 3‐ and 5‐year survival rates after ovarian resection were 40 per cent and 25 per cent, respectively. Right colon cancer (30 per cent right colon vs 60 per cent left colon vs 10 per cent rectum, P = 0.021) and T4 staging of the colonic primary (30 per cent T3 vs 65 per cent T4, P = 0.033) were found to be poor prognostic factors for survival. Conclusion: Although recurrence after resection of Krukenberg tumours is common, bilateral salpingo‐oophorectomy should still be considered. A more aggressive approach, such as debulking surgery or metastasectomy, is also recommended to improve the outcome of these patients.     

Surgery may be curative for patients with a localized perforation of rectal carcinoma

BACKGROUND: Perforation at the time of operation adversely affects the prognosis of rectal cancer. These procedures have been termed 'palliative' or 'non-curative'. The long-term outcome of generalized perforations may be different from that of localized or contained perforations. Although the oncological results may be compromised when the tumour is perforated, results in cases where the perforation is contained may not be as bad as previously thought. An attempt was made to examine the intermediate and long-term results for locally contained perforated rectal cancers. METHODS: Some 848 patients with rectal cancer were operated on between March 1989 and December 1995. Of these, 42 (5 per cent) had a locally contained perforation of the rectum. Median follow-up was 23 (range 12-74) months. RESULTS: The survival of patients with locally contained tumour perforation who underwent resection without macroscopic residual disease (40 per cent at 5 years) was significantly better than that of patients with metastatic disease at the time of surgery (zero at 4 years) (P < 0.01). The survival of patients in whom the tumour was inadvertently perforated during operation was similar to that of patients with locally contained spontaneous tumour perforations. The incidence of local recurrence in these perforated cases was low provided that a wide tumour clearance was achievable at the time of operation. Operative mortality and morbidity rates were not significantly different but the incidence of postoperative wound infection was marginally higher among patients with perforation. CONCLUSION: If clear margins can be obtained at the time of operation the prognosis of locally contained perforated rectal cancers is good and approaches that of a potentially curative resection.     

Management of severe obstruction of the large bowel due to malignant disease

One hundred twenty-four patients with complete bowel obstruction from colorectal cancer requiring emergency surgery were treated between 1961 and 1970. Two thirds of the tumors were distal to the transverse colon. Curative resection was possible in 72 per cent and the over-all mortality was 15 per cent. Forty per cent survived five years after resection for cure. Primary resection was preferred for obstructions of the right side of the colon and the transverse colon, and staged procedures rather than primary resection were more satisfactory for lesions of the left side of the colon and rectum. The mortality rate was lower after transverse colostomy than after cecostomy. Combined perforation and obstruction (twenty-four patients) had a particularly high mortality (42 per cent) and a poor prognosis (14 per cent five year survival).     

Impact of neoadjuvant therapy on postoperative complications in patients undergoing resection for rectal adenocarcinoma

Surgical resection continues to be the mainstay of treatment for rectal cancer. Neoadjuvant therapy (chemotherapy and radiation) has also been shown to be efficacious. The impact of preoperative chemotherapy and radiation on postoperative complications is unclear. The purpose of this study is to evaluate the relationship of neoadjuvant therapy on postoperative complications in patients undergoing a resection of rectal cancer. A total of 325 patients who underwent curative resection for rectal cancer from 1984 to 2001 were retrospectively reviewed. Only cases with complete data sets who had undergone surgery at this institution were evaluable (257). The patients were divided into groups based on the operative procedure performed; abdominoperineal resection (APR) versus sphincter-sparing (SS) procedures (LAR/Transanal) and whether or not preoperative chemotherapy or radiation was administered. There was no significant difference between complication rates for APR and SS with 19 per cent and 14 per cent, respectively. The preoperative therapy had no effect on complications after APR. However, the SS group showed 21 per cent of the patients who received radiation had complications compared to 11 per cent in those who did not (P = 0.087). Complications in the SS group included leaks, wound infections, abscess, embolism, cardiac dysrhythmias, and myocardial infarctions. The 30-day mortality was 1.9 per cent for the entire cohort with no clear difference between groups. There was no significant difference in complication rate between APR and SS. In the APR group, neoadjuvant therapy had no impact on the incidence of complications. However, the SS group did show a trend between preoperative chemotherapy and radiation and complication rate. However, this may not outweigh the advantages of preoperative therapy in this setting.     

Functional results of delayed coloanal anastomosis after preoperative radiotherapy for lower third rectal cancer

Background: The aim of this study was to assess functional outcomes of patients who had a delayed coloanal anastomosis for a lower third rectal cancer after preoperative radiotherapy.

Study Design: From January 1988 to December 1997, 35 patients with an adenocarcinoma of the lower third of the rectum received preoperative radiotherapy (45 Gy) followed by a rectal resection, combining an abdominal and transanal approach. Colorectal resection was performed about 32 days after the end of the radiotherapy. The distal colon stump was pulled through the anal canal. On postoperative day 5 the colonic stump was resected and a direct coloanal anastomosis performed without colostomia diversion.

Results: There was no mortality. There was no leakage. One patient had a pelvic abscess. One patient had a necrosis of the left colon requiring reoperation. Another delayed coloanal anastomosis could be performed. Median followup was 43 months (range 6 to 113 months). Functional results were evaluated with a new scoring system including 13 items. Function was considered good in 59% and 70% at 1 and 2 years, respectively.

Conclusions: This new procedure is a safe and effective sphincter-preserving operation that avoids a diverting stoma for patients with rectal cancer of the lower third of the rectum. This technique is well adapted for patients receiving preoperative radiotherapy, with low local morbidity and good functional results. Further adaptation could be imagined for a coelioscopic approach.
