Combined resection of the duodenum and pancreas for locally advanced colon cancer

Colorectal cancer invading adjacent organs is a frequent event occurring in 5.5% to 12% of all colorectal malignancies. Colon cancer directly invading the duodenum and pancreas is rare and may require combined resection of the colon, pancreas, and duodenum, which represents a complex operation with significant morbidity and mortality rates. In this article, a case of a 41-year-old patient with a right colon cancer directly infiltrating the duodenum and head of the pancreas is presented. The patient was treated by radical combined resection of the colon, duodenum, and pancreas. Pathological examination confirmed neoplastic invasion of the adjacent organs and absence of lymph node metastasis (T4N0). The patient recovered uneventfully. Patients with colorectal cancer infiltrating adjacent organs such as the duodenum and the pancreas should be treated by radical en bloc resection of the tumor. This procedure is the preferred treatment strategy because it seems to be associated with improved overall survival rates.

Extraperitoneal resection of the right colon for locally advanced colon cancer

Aim Optimal colon cancer surgery correlates with a reduction in recurrence rate and improved overall prognosis. This technical note describes the extraperitoneal approach for locally advanced right colon cancer. Method The retroperitoneal technique, mainly used in pseudomyxoma peritonei resectional surgery, is described in three surgical steps and it is compared with existing surgical approaches for right colon cancer. Results This approach has the advantages of early entry in the retroperitoneal plane well away from the tumour, early recognition and protection of the ureter and minimal manipulation of the tumour‐bearing right colon. Conclusion Extraperitoneal resection of the right colon for locally advanced colon cancer is technically feasible, safe and achieves tumour‐free retroperitoneal margins.     

Combined operations in stomach cancer

The authors make an analysis of their experience with the combined operations for gastric carcinoma in 108 patients. Lethality was 35,2%. Five-year survival was 19,6%. For such operations they recommend the thoraco-abdominal access or extensive transverse laparotomy.     

Combined operations in stomach cancer

Experience with 217 combined operations for gastric cancer have shown them to be expedient. Five-years survival after combined operations for locally spread gastric cancer was obtained in 26,4 +/- 4,2% of the discharged patients.     

Extended resection in locally advanced colon cancer

Colorectal malignant tumors with a mono o multivisceral involvement have a poor prognosis and surgery is the only treatment with a hope to be curative. Aggressive surgical management of locally advanced colo-rectal cancer seems to be justified by good oncological results. At the Institute of Clinica Chirurgica of the University of Trieste 58 extended resections were performed for advanced tumors of colon and rectum. The specific morbidity rate was 24% for standard and 24.1% for extended resections. Operative morality was 15.2%; hystological specimen confirmed in 31 cases neoplastic infiltration of contigous structures. The 5 year survival rate was 38.5% in right colonic tumors and 53.3% in left colonic tumors. The literature favors an aggressive approach when the tumor adhesions are suspected. The excision of adjacent organs, whether or not they are microscopically involved by the tumor, is necessary to avoid leaving potentially curable disease The authors, analyzing their results, have also reported good results by management including resection of the colon and contigous organs if involved. Palliative therapy must be performed only if liver metastases are detected or in those cases when primary resection is not thecnically feable or in patients not able to tolerate the procedure.

Combined radical prostatectomy and abdominoperineal resection for locally invasive rectal cancer

INTRODUCTION

An infiltration of urological organs is found in 5–10% of patients with colorectal carcinoma. Total pelvic exenteration is the standard procedure for locally advanced rectal cancer. In selected patients with rectal cancer involving the prostate or seminal vesicles, the bladder can be preserved and en bloc radical prostatectomy with abdominoperineal rectal resection can be performed. We report two patients who treated with this combined approach.

PRESENTATION OF CASE

Two patients with symptoms of rectal bleeding and pelvic pain were investigated. Colonoscopy demonstrated a tumor in the lower rectum. Biopsies revealed adenocarcinoma. Both pelvic MRI and endorectal ultrasound showed tumors that invaded the prostate and the seminal vesicles directly but without invasion of the bladder. After neoadjuvant chemoradiation, combined radical prostatectomy and abdominoperineal amputation was performed. None has developed local recurrence, but one of them was operated on for a single lung metastasis. After a follow-up of 28 and 20 months, respectively, the patients are alive without evidence of local recurrence or distant disease.

DISCUSSION

This procedure obviates the need for urinary diversion without compromising the local tumor control. Intraoperative and postoperative diagnostic difficulties, and clinical aspects in relation to postoperative anastomotic leak and survival of patients are discussed.

CONCLUSION

En bloc radical prostatectomy and proctosigmoidectomy is feasible in selected patients with rectal cancer and invasion limited to the prostate or seminal vesicles because it provides good local tumor control and significantly improves the patient''s quality of life in comparison to total pelvic exenteration.     

Laparoscopic colon resection for colon cancer

INTRODUCTION: Laparoscopic colon resection for cancer is as yet an unproven operation. This review article summarizes current data on the topic. METHODS: A Medline review identified articles published since 1990 summarizing patients with potentially curable colon cancer who underwent a laparoscopic-assisted colon resection. Only articles that were randomized or had a control group with historical or matched open cases were used. RESULTS: Very few prospective randomized controls exist. Several clinical trials are under way with one completed. Data thus far support some patient benefits with a laparoscopic approach. No differences in morbidity, oncologic data, or survival appear to exist. CONCLUSIONS: The results of ongoing clinical trials are still needed to further evaluate the role of laparoscopic assisted colon resection in patients with potentially curable colon cancer.     

Combined surgical operations for locally spread cancer of the rectum and female genital organs with ablation of remote metastases

The article presents data of 148 combined cytoreductive operations (with ablation of remote metastases) in patients with widespread rectal cancer (in 83 patients) and female genital organs (in 65 patients). The immediate and long-term results suggest that such operations are justifiable in multitype hospitals.     

Local resection of the stomach for gastric cancer

The local resection of the stomach is an ideal method for preventing postoperative symptoms. There are various procedures for performing local resection, such as the laparoscopic lesion lifting method, non-touch lesion lifting method, endoscopic full-thickness resection, and laparoscopic endoscopic cooperative surgery. After the invention and widespread use of endoscopic submucosal dissection, local resection has become outdated as a curative surgical technique for gastric cancer. Nevertheless, local resection of the stomach in the treatment of gastric cancer in now expected to make a comeback with the clinical use of sentinel node navigation surgery. However, there are many issues associated with local resection for gastric cancer, other than the normal indications. These include gastric deformation, functional impairment, ensuring a safe surgical margin, the possibility of inducing peritoneal dissemination, and the associated increase in the risk of metachronous gastric cancer. In view of these issues, there is a tendency to regard local resection as an investigative treatment, to be applied only in carefully selected cases. The ideal model for local resection of the stomach for gastric cancer would be a combination of endoscopic full-thickness resection of the stomach using an ESD device and hand sutured closure using a laparoscope or a surgical robot, for achieving both oncological safety and preserved functions.     

Postoperative radiotherapy for locally advanced colon cancer

Background: The role of adjuvant postoperative radiotherapy for locally advanced colon cancer is not well documented. Methods: Seventy-eight patients who underwent a complete resection of B2-C colon cancer received postoperative radiotherapy. Twenty-eight patients received ⩽45 Gy; 50 patients received 50–55 Gy. Twenty-seven patients received adjuvant fluorouracil-based chemotherapy. All patients were followed for a minimum of 3 years; no patients were lost to follow-up. Results: The overall local control rate was 88%. The 5-year actuarial rate of local control was 96% after 50–55 Gy postoperative radiotherapy compared with 76% after <50 Gy (p=0.0095). Multivariate analysis of local control showed that only radiotherapy dose significantly influenced this end point. Cause-specific survival rates at 5 years were B2, 67%; B3, 90%; C1, 100%; C2, 61%; C3, 36%; and overall, 63%. Multivariate analysis of cause-specific survival showed that only stage significantly influenced this end point. Bowel obstruction caused by adhesions developed in three patients and required a laparotomy; radiation-induced sarcoma developed in one additional patient. Conclusions: Postoperative radiotherapy appears to reduce the risk of local recurrence in patients with locally advanced colon cancer. The optimal dose is probably 50–55 Gy at 1.8 Gy per fraction. Postoperative radiotherapy may improve cause-specific survival for patients with stages B3 and C2 cancers.     

En bloc resection of the duodenum for locally advanced right colon adenocarcinoma

Direct invasion of colorectal adenocarcinoma into adjacent structures occurs frequently, but only rarely is the duodenum involved. This study was undertaken to assess the safety and efficacy of en bloc resection of locally advanced right colon carcinoma invading the duodenum. A retrospective review of 49 patients with locally advanced colon cancer, surgically managed between 2000 and 2005, was performed. Forty-six patients underwent en bloc resection of colon and adjacent organs not involving the duodenum. Three patients with duodenal invasion underwent en bloc partial duodenectomy. The mean operative blood loss, length of stay, postoperative morbidity, and mortality compare favorably between these two groups of patients. Of the 46 patients with en bloc resection of other organs, 27 are alive at 12 to 60 months follow up. Two patients with duodenal invasion are alive without recurrence at 15 and 20 months follow up. En bloc resection of colon cancer invading the duodenum can be performed safely because morbidity and mortality rates are comparable to those attending extended resections of other locally advanced colon carcinomas. Overall survival in patients who underwent surgery with curative intent justifies en bloc duodenal resection in selected patients.     

Combined operations in diseases of the stomach and duodenum

The article generalizes the experience in treating 137 patients with diseases of the stomach and duodenum. The largest group included 82 persons with peptic ulcer; 45 had carcinoma of the stomach; 5 had benign tumors of the stomach, and 5 persons had chronic duodenal obstruction. The most common concurrent disease was cholelithiasis (102 patients), it was diagnosed before the operation in 70% of patients with peptic ulcer and in 85% of those with carcinoma of the stomach. Among the less predominant diseases were abdominal hernias (12 patients), cysts of various localization (7), varicosity (3), chronic appendicitis (3), atherosclerosis obliterans (2), ect. Organ-preserving operations were carried out as the main stage of surgery in most patients with peptic ulcer. The nature of the simultaneous operations corresponded to the concomitant surgical diseases. Most of the operations (125) were performed through a median laparotomy approach; superior median laparotomy was mostly resorted (115 patients). Four (2.9%) patients died after the operation. It is pointed out that patients with gastroduodenal diseases must be thoroughly to reveal concurrent surgical diseases.     

Two successful curative operations using stomach-preserving distal pancreatectomy with celiac axis resection for the treatment of locally advanced pancreatic body cancer

Large vessel invasion is a serious factor determining whether an operation for pancreatic body cancer is feasible. The Appleby operation is a radical operation for the treatment of pancreatic body cancer that has infiltrated the celiac axis. Since this procedure includes a total gastrectomy, the operation is associated with a high morbidity, mortality, and deteriorating postoperative quality of life (QOL). We experienced two cases in which radical operations consisting of a stomach-preserving distal pancreatectomy with en bloc resection of the celiac, common hepatic, and left gastric artery were performed. The use of adjuvant chemotherapy in these cases led to a good postoperative QOL.     

Abdominosacral resection for locally recurring rectal cancer

AIM To investigate feasibility and outcome of abdominalsacral resection for treatment of locally recurrent rectal adenocarcinoma.METHODS A population of patients who underwent an abdominalsacral resection for posterior recurrent adenocarcinoma of the rectum at the National Cancer Institute of Milano, between 2005 and 2013, is considered. Retrospectively collected data includes patient characteristics, treatment and pathology details regarding the primary and the recurrent rectal tumor surgical resection. A clinical and instrumental follow-up was performed. Surgical and oncological outcome were investigated. Furthermore an analytical review of literature was conducted in order to compare our case series with other reported experiences.RESULTS At the time of abdomino-sacral resection, the mean age of patients was 55(range, 38-64). The median operating time was 380 min(range, 270-480). Sacral resection was performed at S2/S3 level in 3 patients, S3/S4 in 3 patients and S4/S5 in 4 patients. The median operating time was 380 ± 58 min. Mean intraoperative blood loss was 1750 m L(range, 200-680). The median hospital stay was 22 d. Overall morbidity was 80%, mainly type Ⅱ complication according to the ClavienDindo classification. Microscopically negative margins(R0) is obtained in all patients. Overall 5-year survival after first surgical procedure is 60%, with a mediansurvival from the first surgery of 88 ± 56 mo. The most common site of re-recurrence was intrapelvic.CONCLUSION Sacral resection represents a feasible approach to posterior rectal cancer recurrence without evidence of distant spreading. An accurate staging is essential for planning the best therapy.
