Comparison of short-and long-term outcomes following either insertion of self-expanding metallic stents or emergency surgery in malignant large bowel obstruction

BACKGROUND: Self-expanding metallic stents (SEMS) are now regarded as a safe and effective treatment for an acute obstructing colorectal cancer. SEMS insertion is an invasive procedure that could potentially worsen prognosis. This study assessed the short-and long-term outcomes in patients stented for acute large bowel obstruction and in patients who underwent primary emergency surgery. METHODS: We retrospectively identified 19 patients who underwent SEMS insertion and 23 patients who had primary emergency surgery for left-sided large bowel obstruction as the first presentation of colorectal cancer. RESULTS: There were no significant differences between the 19 patients in the SEMS group and the 23 patients in the primary emergency surgery group in terms of demographics and tumour location and stage. Stent insertion was successful in 16 patients (84%). One patient died from a stent-related perforation and another had a stoma fashioned for stent migration. Stents were a definitive procedure in 2 patients with advanced disease and acted as a "bridge to surgery" in the remaining 12 patients. Compared to the primary surgery group, there was a trend towards a higher primary anastomosis rate in the SEMS group (p=0.08); there were no significant differences in length of hospital stay, 30-day mortality or complication rates between the groups. Long-term prognosis (estimated 3-year survival) did not differ significantly between the groups (p=0.54); this persisted when only curative resections were considered (p=0.80). CONCLUSIONS: Preoperative stent insertion is a safe and effective treatment for large bowel obstruction, and may result in a higher primary anastomosis rate. Stent insertion does not seem to have a deleterious effect on prognosis.     

Lymphadenectomy in pulmonary metastasectomy

Lymph node (LN) removal during pulmonary metastasectomy is a prerequisite to achieve complete resection or at least collect prognostic information, but is not yet generally accepted. On average, the rate of unexpected lymph node involvement (LNI) is less than 10% in sarcoma, 20% in colorectal cancer (CRC) and 30% in renal cell carcinoma (RCC) when radical LN dissection is performed. LNI is a negative prognostic factor and presence of preoperative mediastinal disease usually leads to exclusion of the patient from metastasis surgery. Nonetheless, some authors found excellent prognoses even with mediastinal LNI in colorectal and RCC metastases when radical LN dissection was performed (median survival of 37 and 36 months, respectively). Multiple metastases, central location of the lesion followed by anatomical resections are associated with a higher LNI rate. The real prognostic influence of systematic LN dissection remains unclear. Two positive effects were described after radical lymphadenectomy: a trend for improved survival in RCC patients and a reduction of mediastinal recurrences from 23% to 0% in CRC patients. Unfortunately, there is a great number of studies that do not demonstrate any positive effect of lymphadenectomy during pulmonary metastasectomy except a pseudo stage migration effect. Future studies should not only focus on survival, but also on local and LN recurrence.     

Evaluation of P-POSSUM in Surgery for Obstructing Colorectal Cancer and Correlation of the Predicted Mortality With Different Surgical Options

PURPOSE This study examined the accuracy of Portsmouth Physiologic and Operative Severity Score for enUmeration of Mortality and Morbidity system (P-POSSUM) in predicting the mortality of patients who underwent operations for obstructing colorectal cancer. It also is attempted to analyze the actual mortality and the predicted P-POSSUM mortality of different surgical options for obstructing left-sided cancer.METHODS Data on patients who underwent surgery for obstructing colorectal cancer during 1998 to 2002 were collected. Mortality predicted by P-POSSUM was compared to the actual mortality with the method of linear analysis. The accuracy of using P-POSSUM to predict mortality in this group of patients was assessed by Hosmer and Lemeshow goodness of fit test and Receiver Operator Characteristic curve analysis. The predicted and actual mortality of patients who underwent different surgical options also were analyzed.RESULTS A total of 160 patients were included in the study and 18 patients died postoperatively. The operative mortality was 11.3 percent. P-POSSUM predicted overall mortality of 15 percent. The observed and predicted mortality was found to have no significant lack of fit (chi-squared = 5.98; degree of freedom = 3; P = 0.11). The area under Receiver Operator Characteristic curve analysis was 0.75. For patients with left-sided tumors, P-POSSUM predicted mortality and actual mortality of patients who had resection without anastomosis were both significantly higher than patients with single-stage resection and primary anastomosis ( P = 0.044 and 0.011, respectively).CONCLUSIONS P-POSSUM system is valid for prediction of overall mortality in patients with operations for obstructing colorectal cancer. Estimation of P-POSSUM predicted mortality during operation and its ability to correlate with choice of procedure is an area that is worth further study in emergency colorectal surgery.Reprints are not available.     

Colorectal carcinoid tumors--own experience

Symptomatology, diagnostics and treatment problems in 5 patients with colorectal carcinoid are presented. From 1974 to 1999 in the Clinic of Endocrinological and General Surgery of the Medical University of Lód?, 3001 patients underwent surgery due to acute appendicitis and 431 for colorectal cancer. Among them, there were 5 patients in whom the histological examination revealed colorectal carcinoid. The carcinoids were localized in the appendix in 4 patients and in the left colon flexure in 1 patient. The mean age of these 5 carcinoid patients at the time of diagnosis was 38.4 years (range 18-72 yr). The female-to-male ratio amounted to 4:1. The symptoms of all 5 patients was not typical for carcinoid of the colon. In four surgery was performed for acute appendicitis and one patient complained of chronic obstipation and pain in the left epi- and mesogastrium. The double-contrast examination of the large intestine revealed tumor of the left colon flexure. Four carcinoid patients with the signs of acute appendicitis had emergency surgery. The carcinoid tumors were diagnosed microscopically after surgery only. In 3 of them the tumor extended beyond the appendix and a reoperation was performed. In one patient with the tumor of small diameter (5 mm) involving only the mucosa and submucosa a reoperation was not indicated. In 3 reoperated patients right hemicolectomy with regional lymphadenectomy was performed. The patient with the tumor of the left colon flexure diagnosed preoperatively underwent radical surgery with regional lymphadenectomy. The postoperative histological examination of the tumor confirmed carcinoid. No carcinoid metastases were found in lymph nodes of all studied cases. Until today, all 5 carcinoid patients are alive with no signs of local reccurrence or distant metastases over the 1-20 year follow-up period.

Treatment outcomes of hepatic and pulmonary metastases from colorectal carcinoma

Background and Aim:  The resection of synchronous or metachronous pulmonary and liver metastasis is an aggressive treatment option for patients with stage IV colorectal cancer and has been shown to yield acceptable long-term survival. We reviewed our experience with colorectal cancer patients with both liver and lung resections to determine the efficacy of surgical resections.
Methods:  We performed a single institution, retrospective analysis of all patients who underwent surgical hepatic and pulmonary resection for metastatic colorectal cancer between 1995 and 2004.
Results:  A total of 32 patients underwent resection of both hepatic and pulmonary metastases secondary to colorectal cancer. The 5-year overall survival from initial operation was 60.8%. The disease-free interval was 44.3 months (95% confidence interval: 24.7 and 63.8, respectively). Neither the number of pulmonary lesions nor the time interval between the primary surgery and the metastasectomy had a significant impact on survival ( P  = 0.134).
Conclusion:  An aggressive surgical treatment of selected colorectal cancer patients with lung and liver metastases resulted in prolonged survival. The 5-year survival rate of 60.8% with no perioperative mortality was observed in our study.     

Outcome of Patients on Renal Replacement Therapy after Colorectal Surgery

Purpose  Patients on renal replacement therapy are reported to have a high complication rate after abdominal surgery, the result of uremia and immunosuppression. A review of this group of patients undergoing colorectal surgery was undertaken. Methods  Seventy-three separate colorectal operations were performed for 44 patients. Thirty-eight patients were on dialysis and 35 had a renal transplant. Data (coexisting disease, preoperative blood results, operative details, complications, and colorectal POSSUM score) were completed for each surgical event. Results  Forty-two elective and 31 emergency procedures were performed. Infective complications were common (overall 60 percent). There were two anastomotic leaks in the elective group, but five leaks from seven emergency anastomoses. Stomas were frequently raised. Ninety percent of patients who survived and had a defunctioning stoma underwent a successful reversal. The overall major complication rate after elective and emergency surgery was 19 and 81 percent, respectively, and mortality was 5 and 26 percent, respectively. Conclusions  Renal patients have a high rate of complications after colorectal surgery, and emergency surgery has a significant risk of anastomotic leak. Primary anastomosis should be avoided in all patients undergoing emergency intestinal resections. Subsequent surgery to restore intestinal continuity is possible in 90 percent of patients with far fewer complications. Presented at the meeting of the Royal Society of Medicine, Paris, France, May 31 to June 3, 2007, and the meeting of the Association of Surgeons of Great Britain and Ireland, Manchester, England, April 18 to 20, 2007.

Hepatic resections for bilobar liver metastases from colorectal cancer

The present study was performed to assess survival benefits in patients who underwent a hepatic resection for isolated bilobar liver metastases from colorectal cancer. Thirty-eight patients underwent a curative hepatic resection for isolated colorectal liver metastasis. Among them, 11 patients had bilobar liver metastases and 19 had a solitary metastasis. The remaining 8 patients had unilobar multiple lesions. We investigated survival in two groups those with bilobar and those with solitary metastatic tumors. Survival and disease-free survival were 36% and 18% at 5 years, respectively, in the patients with bilobar liver metastases, while these survivals were 43% and 34% in the patients with solitary liver metastasis. In the 38 patients, repeated hepatic resections were performed in 15 patients with recurrent liver disease. The 5-year survival and disease-free survival rates for these patients were 38% and 27%, respectively, after the second hepatic resections. Of the 11 patients with bilobar liver metastases, 5 underwent a repeated hepatic resection, and they all survived for over 42 months. Based on our observations, a hepatic resection was thus found to be effective even in selected patients with either bilobar nodules or recurrence in the remnant liver.     

Minimally invasive colorectal surgery

Adoption of laparoscopic colorectal surgery has been slow. In the United States, of approximately 250,000 colectomies each year, only 5% to 15% of these cases are being done laparoscopically. Laparoscopic colorectal surgery can be performed successfully on patients for both benign and malignant conditions in any anatomic location of the colon and rectum. The COST trial definitively established that laparoscopic colon surgery for cancer had similar rates of local recurrence and survival compared to open surgery, with better short-term outcomes. It demonstrated that laparoscopic resections resulted in shorter hospital stays, decreased IV narcotics and oral analgesics, and improved quality of life within two weeks of surgery. In the authors' clinical experience of more than 1500 laparoscopic surgeries, patients who undergo laparoscopic colorectal surgery experience decreased rates of wound infection, hernia, and bowel obstruction. One of the challenges of laparoscopic colorectal surgery is standardizing these complex, minimally invasive procedures in the operating room. With standard techniques, one can create optimal outcomes for patients, minimizing perioperative complications and maximizing oncologic results. This paper describes a sequenced step approach for each procedure to facilitate this. Left colectomy follows a nine-step process, and right colectomy follows a four-step process. Both of these procedures are described in detail. The newest horizon in minimally invasive surgery is single incision surgery, which allows for colorectal resections through a single 2.5 cm incision, producing an excellent cosmetic result. Based on this chapter, we advocate the laparoscopic approach be used as the primary method for colorectal surgery.     

Emergency surgery for patients with colorectal cancer over 90 years of age

BACKGROUND/AIMS: Colorectal cancer has an extremely poor prognosis in the elderly with high rates of emergency presentation and perioperative mortality. This report examines our experience and results in the emergency treatment of patients older than 90 years with colorectal cancer. METHODOLOGY: From 1995 to 2000, 486 patients with colorectal cancer were operated on in an emergency surgery situation at the Department of Emergency Surgery of Sant'Orsola-Malpighi University Hospital. A retrospective analysis of 20 patients aged 90 or older was carried out. RESULTS: Thirteen patients underwent resection of the primary growth and anastomosis and 7 subjects with carcinomatosis had palliative intervention by creating a stoma only or bypass anastomosis without resection. We registered two deaths caused by respiratory insufficiency and 2 postoperative complications successfully treated with medical therapy. CONCLUSIONS: Emergency surgery for colorectal cancer in patients over 90 years of age can be performed safely without restrictions related to the age.     

Carcinoma of the head of the pancreas

BACKGROUND/AIMS: Extended radical surgery might provide a survival advantage for patients with carcinoma of the head of the pancreas. METHODOLOGY: Between January 1980 and December 1999, 144 patients with carcinoma of the head of the pancreas were treated in a community hospital setting, of whom 69 patients who underwent radical surgery were retrospectively reviewed. Surgical procedures included standard pancreaticoduodenectomy (27 patients), pylorus-preserving pancreaticoduodenectomy (27 patients), and total pancreatectomy (15 patients). Portal vein resection was performed for 15 patients. Retroperitoneal lymphadenectomy was performed for 35 patients. No patients received adjuvant chemotherapy or radiotherapy. RESULTS: The surgical resection rate was 47.9% with a surgical mortality rate of 4.3% during this period. The overall 5-year survival rate after radical surgery was 16.1% with a median survival of 12 months. Seven patients survived five years, making 16.3% of the patients available for a more than 5-year follow-up. Long-term survivors had less than two positive lymph nodes in the posterior pancreatic head. Fourteen of 15 patients undergoing portal vein resection died within 21 months. One patient having no portal vein invasion microscopically survived 27 months without recurrence. CONCLUSIONS: Extended radical surgery did not prolong survival for patients with carcinoma of the head of the pancreas.     

Outcome and complications of stenting for malignant obstruction

Malignant colorectal obstruction is not an uncommon clinical condition as it is frequently cited that obstruction occurs in 7%-29% of patients with colorectal cancer. The severity of this condition is illustrated by its high postoperative mortality (up to 24%) and morbidity (up to 78%) rates after these patients have undergone conventional emergency resection of the obstructing tumor. In the past decade, the application of self-expandable metal stents (SEMSs) as treatment of malignant large bowel obstruction has expanded rapidly to reduce these alarming numbers by ‘bridge to surgery’ treatment from an emergency to an elective operation. However, the randomized controlled trials published on this topic show conflicting results regarding the outcome of SEMS placement as a bridge to surgery. Recently, a number of meta-analyses have been published on the outcomes of SEMS placement as bridge to surgery compared with emergency surgery, and data are also developing on the long-term oncological consequences of preoperative SEMS placement in the curative setting of malignant large bowel obstruction. Therefore, this review provides an overview of the current evidence on the use of SEMSs in the treatment of malignant large bowel obstruction.     

Minimally invasive resection for colorectal cancer: perioperative and medium-term results in an unselected patient group at a single institution

Background The use of laparoscopy for colorectal cancer resection is still controversial. Methods We prospectively analyzed the outcome of minimally invasive resection for colorectal cancer, performed at our institution from 1998, when laparoscopic surgery became the treatment of choice for colorectal cancer, until 2004. All patients undergoing elective resection were assessed in terms of perioperative results (duration of surgery, number of lymph nodes removed, length of specimen, rate of conversion, complications) and survival. Patients were assessed yearly with follow-up visits and telephone interviews. Results In the study period, 302 patients (mean age 66.1 years; range, 32–93 years) underwent 114 left hemicolectomies, 108 low anterior resections, 61 right hemicolectomies, 12 Miles procedures, 4 subtotal colectomies, and 3 transverse colon resections. Surgery took an average of 226 minutes (SD=71 min). The number of lymph nodes removed was 14±8. The conversion rate was 10%; most of the conversions were due to locally advanced cancer (15 cases) and bowel distension (7 cases). Fifteen anastomotic leaks were observed (5%). Twenty patients needed reoperation and two died: one of septic shock due to an anastomotic leak; the other of electrolyte imbalance and dehydration after peritonitis due to a bowel loop injury. Follow-up was available for 91% of patients. Cancer-related survival curves showed a 90% survival for stage II, 85% for stage III, and 10% for stage IV disease, 30 months after surgery. Conclusions Minimally invasive laparoscopic resection for colorectal cancer enables an oncologically adequate resection with complication and survival rates that are no worse than are to be expected after traditional open surgery. Locally advanced tumor and bowel distension are the most frequent reasons for conversion to open surgery. An erratum to this article is available at .     

Resection of liver metastases from colorectal cancer

PURPOSE: This study was undertaken to determine the indications for and value of liver resection for metastases from colorectal cancer. METHODS: From 1978 through 1991, 66 patients were operated on for liver metastases from colorectal cancer. All patients had had a curative resection of their colorectal cancer. Forty resections of the liver were major anatomic resections. RESULTS: Five patients died in the postoperative period. All resections were intended to be curative, but in 16 of the patients the resection became noncurative. None of these patients lived more than two years after liver resection. Fifty patients with a curative resection had a three-year survival rate of 36 percent, postoperative death included. Recurrence in the liver was observed in 30 patients (60 percent) from 3 to 33 (median, 11) months after the liver resection. Four patients had repeated resections performed. Two of them are alive without recurrences 34 and 60 months after the first liver resection, respectively. The difference in survival between curative and noncurative liver resection was highly significant (P=0.01). CONCLUSIONS: Sex, age, Dukes stage of primary colorectal cancer, synchronous or metachronous appearance of metastases, or number of metastases could not predict long-term prognosis. The only factors of predictive value were tumor size less than 4 cm in diameter, a free resection margin, and no extrahepatic tumor. If it is possible to do a curative resection, there should be few contraindications against liver surgery as it is the only treatment that can demonstrate long-term survival for approximately one-third of the patients, and it is the only possibility of a cure.     

Management of recurrent rectal cancer： A population based study in greater Amsterdam

AIM： To analyze, retrospectively in a populationbased study, the management and survival of patients with recurrent rectal cancer initially treated with a macroscopically radical resection obtained with total mesorectal excision （TME）.
METHODS： All rectal carcinomas diagnosed during 1998 to 2000 and initially treated with a macroscopically radical resection （632 patients） were selected from the Amsterdam Cancer Registry. For patients with recurrent disease, information on treatment of the recurrence was collected from the medical records.
RESULTS： Local recurrence with or without clinically apparent distant dissemination occurred in 62 patients （10%）. Thirty-two patients had an isolated local recurrence. Ten of these 32 patients （31%） underwent radical re-resection and experienced the highest survival （three quarters survived for at least 3 years）. Eight patients （25%） underwent non-radical surgery （median survival 24 rno）, seven patients （22%） were treated with radio- and/or chemotherapy without surgery （median survival 15 mo） and seven patients （22%） only received best supportive care （median survival 5 too）. Distant dissemination occurred in 124 patients （20%） of whom 30 patients also had a local recurrence. The majority （54%） of these patients were treated with radio- and/or chemotherapy without surgery （median survival 15 mo）. Twenty-seven percent of these patients only received best supportive care （median survival 6 mo）, while 16% underwent surgery for their recurrence. Survival was best in the latter group （median survival 32 mo）.
CONCLUSION： Although treatment options and survival are limited in case of recurrent rectal cancer after radical local resection obtained with TME, patients can benefit from additional treatment, especially if a radical resection is feasible.     

Multiviszerale und Standardresektionen bei kolorektalen Karzinomen

Purpose

The current study was designed to identify prognostic factors for long-term survival in patients with advanced colorectal cancer in a consecutive cohort.

Methods

A total of 123 patients were operated because of T4 colorectal cancer between 1?January 2002 and 31?December 2008 in the Clinic of Surgery, UK-SH Campus Luebeck.

Results

A total of 78 patients underwent a multivisceral resection. The postoperative morbidity was elevated in the patient group with multivisceral resections (34.6% vs. 26.7%). Nevertheless, we detected no significant differences concerning 30?days mortality (7.7% vs. 8.9%; p=0.815). The main prognostic factor that reached significance in the multivariate analysis was the possibility to obtain a R0 resection (p<0.0001) resulting in a 5-year survival rate of 55% for patients with curative resection. There were no statistically significant differences in 5-year survival between multivisceral and non-multivisceral resections (p=0.608). Also we were not able to detect any significant differences for cancer of colonic or rectal origin (p=0.839), for laparoscopic vs. open procedures (p=0.610), and for emergency vs. planned operations (p=0.674). Moreover, the existence of lymph node metastases was not a predictive factor concerning survival as there was no difference between patients with and without lymph node metastases (p=0.658).

Conclusions

Multivisceral resections are associated with the same 5-year survival as standard resections. Therefore, the aim to perform a R0 resection should always be the main goal in surgery for colorectal cancer. In planned operations, a laparoscopic approach is justified in selected patients.     

Results of a rigorous follow-up system in colorectal cancer

Results of a computer-aided follow-up programme for patients with colorectal cancer are analyzed. Between 1978 and 1987 1293 patients underwent this programme, the drop-out rate was 17%. 299 recurrences in 168 patients were discovered (40% local recurrence, 29% liver metastases and 31% others). Fifty-one per cent of patients with local recurrence and 47% with liver metastases were symptom free. Radical surgery could be performed in 50% of local recurrences and in 26% of liver metastases. The three year survival rate after radical surgery for recurrence was 35% for local recurrences and 33% for liver metastases, the five-year-survival rate 23% and 15%, respectively.     

Factors affecting the prognosis of anatomical liver resection for liver metastases from colorectal cancer

BACKGROUND/AIMS: Liver resection has improved the survival of colorectal cancer patients with metastases. However, there are groups at high risk of recurrence after liver resection. This report reviews our results using anatomical liver resection and analyzes the prognostic factors. METHODOLOGY: We analyzed 78 patients who underwent anatomical liver resection of liver metastases from colorectal cancer between June 1988 and March 2002. RESULTS: Twenty-nine patients had synchronous metastases, and 49 had metachronous. The 5-year overall survival rate was 43%. Patients with more than three metastatic tumors had a significantly poorer 5-year recurrence-free survival rate. There was no statistical difference in the 5-year overall survival rate between patients with metachronous metastases (41%) and those with synchronous (44%) metastases. The 5-year overall survival rate was significantly poorer for patients with an interval of 1 year or less between colorectal and liver resections than for patients with a longer interval. Recurrence after liver resection occurred in 38 patients (49%). The recurrences occurred in the lung in 18 patients, in remnant liver in 15 patients, in lymph nodes in 7 patients, and in other organs in 6 patients. CONCLUSIONS: We conclude that anatomical liver resection of liver metastases from colorectal cancer improves survival. Liver metastases that occur within 1 year of colorectal resection may need an interval of observation before liver resection.     

Surgical resection for colon cancer: laparoscopic assisted vs. open colectomy

BACKGROUND/AIMS: Laparoscopic surgery has been considered for more than a decade for treatment of colorectal cancer. Although its benefits in term of postoperative comfort and parietal preservation are commonly accepted, its efficiency to achieve proper oncologic resection and to prevent tumor recurrence are still debated. The purpose of this retrospective study is to compare results of a minimally invasive laparoscopic approach to these of open surgery for treatment of colorectal cancer. METHODOLOGY: From January 1st 1999 to September 30th 2004, 239 patients underwent colorectal cancer resections; 28 of these patients underwent surgery in an emergent context and were excluded from this study. Accurate follow-up was available for 165 of the 239 patients (69%). For the study, 165 patients were divided into 3 groups: 39 patients underwent a laparoscopically assisted surgery (L group), 120 patients underwent an open colectomy (O group) and 6 patients initially treated with a laparoscopic approach were converted to open colectomy (L/O group) (conversion rate: 8.8%). RESULTS: Sex ratio, mean age and A.S.A. score, as well as patients' past records were similar in the 3 groups. Histological staging was more often stages 3 and 4 in the O group (62.5%) comparing to the L group (41%) (p < 0.5). Mean operating time was slightly longerwhen a laparoscopically assisted approach was used. Overall early mortality rate of this study was 1.8%. Combined local and general overall morbidity rate was 36%. Overall incidence of anastomotic fistulae was 4% and reintervention rate during the early postoperative period was 8%. Postoperative ileus period was often longer for patients of the O group but without statistical significance. Mean duration of hospital stay was similar in the 3 groups. Data concerning surgical resection did not show any difference between groups. None of the patients experienced a metastatic skin settlement. Overall anastomotic stenosis rate was low (2%). The overall locoregional recurrence rate was 12%, without difference between the 3 groups. Forty-two percent of these recurrences were secondarily treated by curative surgery. Similar survival rates as well as oncological spreading frequencies were found. CONCLUSIONS: Results obtained when comparing minimal invasive laparoscopically assisted surgery to open procedure are similar and efficient.
