Management of obstructive colorectal cancer with endoscopic stenting followed by single-stage surgery: open or laparoscopic resection?

BACKGROUND: About one-third of patients with colorectal carcinoma present with acute colonic obstruction requiring emergency surgery. Current surgical options are intraoperative lavage and resection of the colonic segment involved with primary anastomosis, subtotal colectomy with primary anastomosis, colostomy followed by resection, and resection of the colonic segment involved with end colostomy (Hartmann's procedure) requiring a second operation to reconstruct the colon. These procedures present risks and a poor quality of life. Endoscopic colonic stent insertion can effectively decompress the obstructed colon, allowing bowel preparation and elective resection. METHODS: The authors present their experience managing 31 patients with obstructing colorectal cancer who underwent endoscopic colonic decompression with self-expanding metallic stents. A total of 16 patients were treated with open resection, and 6 underwent a laparoscopic resection. The remaining 9 patients were managed with endoscopic palliation and adjuvant therapy. Of the 31 patients, 17 were treated with postoperative chemotherapy. RESULTS: The mean interval between stenting and surgery was 11 days (range, 1-21 days). There was no intraoperative morbidity. The incidence of postoperative morbidity was 20% for open surgery and 0% for laparoscopic surgery. The mean postoperative hospital stay was 13 days for the open surgery group, and 7 days for the laparoscopic group (p = 0.003). The hospital mortality rate was 3.2%. Follow-up evaluation was completed for 96% of the patients. The minimum follow-up period was 15 months. All the patients in the palliative group died of disease, with a median survival of 3 months. Of the 22 surgically treated patients, 17 (77%) are alive at this writing. CONCLUSION: This initial experience shows that after successful endoscopic stenting of malignant colorectal obstruction, elective surgical resection can be performed safely. The presence of the endoluminal stent does not prevent a laparoscopic approach. The combined endoscopic and laparoscopic procedures are a less invasive alternative to the multistage open operations and offer a faster recovery.     

Laparoscopic colorectal resection for endometriosis

Background The rectosigmoid colon is affected by deep pelvic endometriosis in 3–37% of cases. In the past, treatment of the affected gastrointestinal tract generally required conversion to conventional surgery. We describe our experience with complete laparoscopic management of deep pelvic endometriosis with bowel involvement.Methods From March 1995 to March 2003, 29 consecutive patients with endometriosis requiring laparoscopic intervention were evaluated. In seven patients (24%) colorectal involvement was identified prior to the operation. A low anterior resection was performed in four patients (57%) and a sigmoid resection in three (43%). In all cases, colonoscopy showed a normal mucosa. In all cases, treatment consisted of resection of the bowel involved together with the excision of all other implants. Data analysis included age, previous abdominal operations, previous history of endometriosis, operative time, conversion rate, complications, length of stay, and pain relief.Results There were seven patients with colorectal involvement whose median age was 32.8 years (range, 28–40), with a history of previous abdominal operation in two (28%). Preoperative symptoms were as follow: dysmenorrea in four patients (57%), dyspareunia in four (57%), pelvic pain in seven (100%), rectal bleeding in one (14%), and tenesmus in five (71%). Mean operative time was 190 min (range, 165–230). Length of stay was 8.3 days (range, 7–11). There were no anastomotic leak and no major postoperative complication. One patient had temporary urinary retention. At a median follow-up of 38.7 months (range, 1–84), complete relief of pelvic symptoms was achieved in five patients (71%), and there was improvement in one patient. In one patient complaining of persistent pain, a new colonic implant was diagnosed two years after the surgery requiring reoperation.Conclusions The results show that provided that the surgeon is highly skilled in laparoscopy, laparoscopic resection of deep pelvic endometriosis with rectosigmoid involvement is feasible and effective in nearly all patients.     

Laparoscopic surgery for lower gastrointestinal fistulas

Background: Increased experience and improved instrumentation have lead to a reduction in morbidity and a commensurate increase in the spectrum of laparoscopic indications. The purpose of this study was to assess the feasibility of laparoscopic surgery in patients with gastrointestinal fistulas. Methods: Between March 1993 and March 1995, patients with gastrointestinal fistulas who were laparoscopically treated were analyzed for age, gender, diagnosis, type of procedure, operative time, conversion rate, length of postoperative hospitalization, time until oral intake and return of bowel function, morbidity, and mortality. Results: Ten patients (five females; five males) with a mean age of 49.7 (range 20–86) years were preoperatively diagnosed as having the following fistulas: colocutaneous fistula due to diverticulitis (one), enterocolic fistula (two)—due to Crohn's ileocolitis (one) and due to diverticulitis (one)—pouchvaginal fistula after restorative proctocolectomy for familial adenomatous polyposis (two), colofallopian fistula due to diverticulitis (one), rectourethral fistula due to Crohn's disease (one), high transsphincteric fistula due to perianal Crohn's disease (one), enteroenteric fistula due to Crohn's disease (one), and colovesical fistula due to diverticulitis (one). Procedures performed consisted of sigmoidectomy with coloproctostomy (four), ileocolic resection (two), small-bowel resection with ileostomy (one), and diverting loop ileostomy (three). A complex jejunal enterotomy was noted in one (10%) patient. The mean operative time was 195 (range 75–360) min and mean postoperative hospital stay was 6.1 (range 3–12) days. Two additional cases were converted to open procedures for extensive disease (one) and adhesions (one). The patients started oral intake after a mean of 2.2 (range 1–5) days and bowel function returned after a mean of 3.4 (range 2–7) days. One patient required laparotomy on postoperative day 7 for a malrotated loop ileostomy. Conclusions: Laparoscopic colorectal surgery is feasible in patients with simple lower gastrointestinal fistulas. The morbidity rate of 10% and length of hospitalization of 6 days are similar to results after laparoscopic procedures for ``simpler'' colorectal pathology. However, the 30% conversion rate is higher, attesting to the challenging nature of these conditions.     

Laparoscopic recovery continuity after the Hartmann procedure

In the period from January 2003 to June 2009 923 complex laparoscopic colorectal procedures were performed by one surgeon. Data was as-sessed prospectively in a database including 152 variables. In 15 patients (10 f, 5 m), with a median age of 61 years (range: 35-83 years), discontinuity resection of the colon was performed including 3 patients with open discontinuity resection of the sigma and 12 patients with laparoscopic Hartmann procedures. In all cases continuity of the -colon was recovered laparoscopically. Median op-er-ation time was 100 min, conversion to an open procedure was not necessary. No intra-operative complications occurred and only one wound infection (6.6 %) was recorded postoperatively with a median postoperative stay of 8 days. Although the laparoscopic approach to recover continuity of the colon is technically challenging, we con-clude that the experienced bowel surgeon is able to perform the laparoscopic approach with a low morbidity and mortality by retaining the well known advantages of laparoscopic colonic sur-gery.

Laparoscopic Bowel Resection in the Setting of Metastatic Colorectal Cancer

Background This study aimed to review the outcomes of laparoscopic colorectal resection for patients with stage IV colorectal cancer. Methods From the prospectively collected database for patients who underwent surgery for colorectal cancer in our institution, those with stage IV colorectal cancer who underwent elective resection of tumor during the period from January 2000 to June 2006 were included. The outcomes of those with laparoscopic resection were reviewed and comparison was made between patients with laparoscopic and open resection. Results A total of 200 patients (127 men) with median age of 69 years (range: 25–91 years) were included, and 77 underwent laparoscopic resection. Conversion was required in ten patients (13.0%) and all except one conversion were due to fixed or bulky tumors. There was no operative mortality in the laparoscopic group. The complication rate was 14% and the median postoperative hospital stay was 7 days. When patients with laparoscopic resection were compared with those with open operations, there was no difference in age, gender, comorbidity, or tumor size between the two groups. However, the complication rate was significantly lower in those with laparoscopic resection (14% versus 32%, P = 0.007) and the median hospital stay was significantly shorter (7 days versus 8 days, P = 0.005).The operative mortalities and the survivals were similar in the two groups. Conclusions Colorectal resection can be performed safely in patients with stage IV colorectal cancer. The operative outcomes in terms of complication rate and hospital stay compare favorably with patients with open resection.

Outcomes of endoluminal stenting for distal colorectal cancer: An institutional experience

Aim: The present article aims to review the results of the use of the self‐expanding metallic stent (SEMS) in our institution for distal colorectal tumours, defined as tumours distal to the splenic flexure. Patients and methods: SEMS was selectively offered to the following patients with distal colorectal tumours: (i) patients with clinically obstructed tumours; (ii) patients undergoing palliative treatment; and (iii) patients planned for neoadjuvant chemotherapy. All data, including outcomes and complications, were entered prospectively into a database. A review was carried out for those patients who underwent endoluminal stenting between February 2002 and August 2008. Results: Sixty‐eight patients were evaluated with a median age of 68 years (range 39–91). The median follow up was 11 months. Of these, 53 patients received emergency stenting for acute intestinal obstruction, 12 had palliative stenting for endoscopically obstructive cancer and three had pre‐emptive stenting of locally advanced, stenotic rectal cancer before neoadjuvant chemo‐irradiation. The overall technical success and clinical success rates were 81% and 65%, respectively. Complications included four stent‐related perforations (5.9%) and seven distal migrations (10.3%). Twenty‐seven patients from the intestinal obstruction group and the three patients from the neoadjuvant chemo‐irradiation group subsequently underwent laparoscopic tumour resection with success. Conclusion: In conclusion, our experience showed that SEMS is a useful adjunct in the management of distal colorectal cancer. Apart from being an alternative measure for palliation, SEMS is an effective and non‐invasive way for relieving obstruction in patients with obstructed tumours, allowing them to undergo subsequent one‐stage laparoscopic tumour resection. It is also useful in patients with locally advanced rectal cancer, in whom neoadjuvant chemo‐irradiation is planned.     

Short‐term outcome following elective laparoscopic colorectal cancer resection in octogenarians and nonagenarians

Aim The 30‐day outcome after laparoscopic resection for cancer in patients over the age of 80 years was studied. Method An electronic database was used to identify patients over 80 years who underwent laparoscopic bowel resection between December 2000 and October 2009 at three UK laparoscopic colorectal training units. Patients who required abdominoperineal excision of the rectum were excluded. Results In all, 173 patients (80 men) of median age 84 (80–93) years were identified. American Society of Anesthesiologists (ASA) grades were ASA 1, 14; ASA 2, 87; ASA 3, 68; and ASA 4, 4. Median body mass index was 26 (14–45) kg/m². Thirteen (7.5%) patients were converted to open surgery. The major causes for conversion were bleeding and adhesions. Thirty‐three major complications occurred in 21 (12%) patients. Ten (5.8%) required readmission after discharge for complications giving a total of 17.8% of patients with complications. The median hospital stay was 5 (1–37) days. Three (1.7%) patients died within 30 days of surgery. Conclusion This study confirms that laparoscopic large bowel resection is safe and beneficial in a population over 80 years. It has low morbidity and mortality and a shortened hospital stay. Octogenarians should not be denied major laparoscopic bowel surgery based on age alone.
