A 20 year-old man was hospitalized with an abdominal mass and abdominal distension. Investigations resulted in a diagnosis of ileus caused by advanced colon cancer with peritoneal dissemination to the pouch of Douglas. Palliative surgery was performed to relieve bowel obstruction and debulk the tumor. Histopathological examination showed that the tumor was a mucinous adenocarcinoma invading the serosa without lymph node metastasis. Ascites collected during the operation was diagnosed as class V. Administration of PSK (3.0 g/day) and UFT (600 mg/day) as adjuvant immunochemotherapy was started postoperatively to achieve tumor dormancy. He has been followed as an outpatient for 2.5 years with no ascites or abdominal symptoms.

A 69-year-old man was referred to our department for a cystic tumor, 4.0 cm in diameter, in the lower portion of the right kidney, which was detected by computed tomography. The patient had been admitted to the department of surgery in our hospital for treatment of ileus caused by transverse colon cancer. With a diagnosis of cystic renal cell carcinoma. T2N0M0, in situ non-ischemic tumor enucleation was performed using a microwave tissue coagulator (Microtaze, Heiwa Electronics Industry Inc., Tokyo). The enucleation was accompanied by a defect of the renal pelvis, but it was easily repaired. The operation time was 120 minutes and blood loss was 110 cc. The histological diagnosis was renal cell carcinoma, pT2N0M0V1, expansive, alveolar type, clear cell subtype, G1 > G2. Diagnostic imaging done postoperatively showed no sign of damage to renal function. At the present time, the patient has been disease-free with interferon-alpha for 12 months and is being followed on an outpatient basis. In this report, the advantages of nephron-sparing surgery, especially in situ non-ischemic tumor enucleation using a microwave tissue coagulator for renal tumor are discussed. In particular, the technique of performing tumor enucleation with repair of the defect of renal pelvis used in this case may extend the indication of nephron-sparing surgery.

We analyzed patients who underwent multimodal treatment with peritonectomy as an aggressive treatment for peritonitis carcinomatosis. Peritonectomy was treated in eighteen cases (eleven gastric cancer, seven colon cancer). Out of these eighteen cases, nine were initial operation, six were recurrence after first operation and three were for relief after palliative operation for peritoneal dissemination. Five cases of recurrence included ileus. Of all eighteen patients, ten had received preoperative chemotherapies. Peritonectomy made complete resection possible principle, and the procedure included resection of the primary lesion, subtotal colectomy and peritonectomy. An intestinal stoma was needed in nine cases, consequently. All patients cases underwent continuous hyperthermic peritoneal perfusion (CHPP). Early postoperative peritoneal chemotherapy was given in five cases. By peritonectomy for a first time operation, macroscopically complete resection was possible in six cases. In relief and recurrence cases few tumor cells remained in five cases. Ileus due to peritoneal carcinomatosia was eliminated in all cases, and caloric intake became possible. Fourteen cases had postoperative complication (morbidity 78%), and treatment-related death occurred in three cases (mortality 17%). It became possible to resect even the peritoneal dissemination that was inoperable by conventional surgery, and improvement of QOL was achieved by peritonectomy in cases of carcinomatous peritonitis. However, postoperative care is important since aggression becomes more intense.

We report a case of obstructive ileitis (OI) secondary to colon cancer. A 62-year-old man was hospitalized for abdominal pain and a feeling of fullness. Examinations revealed a mechanical ileus caused by an obstructing carcinomatous lesion of the cecum. He underwent laparotomy on the tenth hospital day, and a right hemicolectomy was carried out with resection of the distended and edematous ileum. The histopathologic diagnosis was adenocarcinoma in the cecum involving the ileocecal valve and nonspecific inflammatory change of the ileum, with mucosal necrosis and neutrophilic infiltration involving the subserosal layer. His postoperative course was uneventful. OI does not always show similar histological features to obstructive colitis; however, they are both important types of obstructing lesions, and their possibility must be kept in mind during colorectal cancer surgery.

We report a case in which l-leucovorin/5-fluorouracil (l-LV/5-FU) combination therapy was remarkably effective for non-resectable advanced descending colon cancer with carcinomatous peritonitis. A 65-year-old man complained of severe abdominal distension, abdominal pain and pulmonary failure, and was diagnosed as having ileus due to descending colon cancer. The patient underwent urgent open laparotomy to release the ileus condition on March 5, 2002. During the laparotomy, we established a diagnosis of nonresectable descending colon cancer accompanied by severe peritoneal dissemination and therefore performed only double-barreled transverse colostomy. The postoperative course was very good. Pathological examination of omental dissemination demonstrated moderately differentiated adenocarcinoma and cytology of ascites was class II. The levels of serum CEA and CA19-9 were within the normal ranges. l-LV/5-FU therapy was initiated postoperatively. Seven cycles of this chemotherapy regimen was performed with no apparent side effect during the treatment. There was no postoperative accumulation of carcinomatous ascites. The patient gained 15 kg compared with body weight admission. On abdominal computed tomography (CT), the primary lesion of the colon decreased 98% and there was no ascites found. To date, there has not been any sign of recurrence during the 19 months of follow-up after this therapy, and we are currently discussing closure of the transverse colostomy. This therapy may be useful for patients with advanced colon cancer accompanied by peritoneal dissemination.

Polyposis of the colon is a colon cancer predisposition syndrome. Familial adenomatous polyposis (FAP) accounts for 1% of the cases of inherited colorectal cancer (CRC). The National Register of inherited CRC and polyposis of the intestines keeps track of 18 patients from 14 families with FAP. Eight of them have been operated of CRC, on 6 patients preventive colectomy with ileorectal anastomosis has been done and four patients refused surgery. Colectomy has been done due to the malignant development also on a female patient with difused juvenile polyposis with adenomatosis. Of three patients under surveillance with the Peutz-Jeghers syndrome, surgery has been done on one female patient with ileus and bleeding large polyps.

Minimally invasive surgical techniques are preferred for a variety of surgical disorders and result in improved outcomes. Laparoscopic colectomy is associated with decreased postoperative pain, faster ileus resolution, shorter hospitalization, and improved cosmesis when compared with open colectomy. The laparoscopic technique is now often preferred for benign disease, but concerns over oncologic adequacy have limited its availability for cancer. The Clinical Outcomes of Surgical Therapy randomized trial of laparoscopic versus open colectomy for cancer recently validated the efficacy of laparoscopy for colon cancer. Limitations include the technical requirements of advanced laparoscopic skills and training, increased operative time, and equipment costs. Surgeons performing laparoscopic colectomy should be adequately experienced and certified to ensure successful outcomes. Despite these limitations, patient recovery benefits may offset the increased operative costs and result in improved cost-effectiveness overall.

In July 2003, a 59-year-old man underwent a right hemicolectomy for sigmoid colon cancer. Hepatic intraarterial injection therapy with 5-FU/CDDP was not only ineffective against a liver metastasis but a lung metastasis was also found, and therefore systemic chemotherapy with CPT-11/5-FU/l-LV (IFL) was administered. After onetime IFL therapy, the CPT-11 was withheld due to ileus. Although 5-FU/l-LV therapy was administered, it was ineffective. IFL therapy was again performed, with the dose decreased by 20%, as part of ambulatory treatment. Not only the liver metastasis but also the lung metastasis decreased significantly in size after one course. In addition, no severe adverse reactions were observed during the treatment, which enabled the therapy to be continued as part of an ambulatory regimen. The results suggest that IFL therapy is effective against colon cancer with lung/liver metastasis and can be administered as part of ambulatory treatment.

The use of prosthetic mesh has become the standard of care in the management of hernias because of its association with a low rate of recurrence. However, despite its use, recurrence rates of 1% have been reported in primary inguinal repair and rates as high as 15% with ventral hernia repair. When dealing with difficult recurrent hernias, the two-layer prosthetic repair technique is a good option. In the event of incarcerated or strangulated hernias, however; placement of prosthetic material is controversial due to the increased risk of infection. The same is true when hernia repairs are performed concurrently with potentially contaminated procedures such as cholecystectomy, appendectomy, or colectomy. The purpose of this study is to report our preliminary results on the treatment of recurrent hernias by combining laparoscopic and open techniques to construct a two-layered prosthetic repair using a four ply mesh of porcine small intestine submucosa (Surgisis, Cook Surgical, Bloomington, IN, USA) in a potentially infected field and a combination of polypropylene and ePTFE (Gore-Tex, W.L. Gore and Associates, Flagstaff, AZ, USA) in a clean field. From September 2002 to January 2004, nine patients (three males and six females) underwent laparoscopic and open placement of surgisis mesh in a two layered fashion for either recurrent incisional or inguinal hernias in a contaminated field. A total of eight recurrent hernia repairs were performed (five incisional, three inguinal) and one abdominal wall repair after resection of a metastatic tumor following open colectomy for colon carcinoma. Six procedures were performed in a potentially contaminated field (incarcerated or strangulated bowel within the hernia), two procedures were performed in a contaminated field because of infected polypropylene mesh, and one was in a clean field. Mean patient age was 56.4 years. The average operating time was 156.8 min. Operative findings included seven incarcerated hernias (four incisional and three inguinal), one strangulated inguinal hernia, and one ventral defect after resection of an abdominal wall metastasis for a previous colon cancer resection. In two of the cases, there was an abscess of a previously placed polypropylene mesh. All procedures were completed with two layers of mesh (eight cases with surgisis and one with combination of polypropylene/ePTFE). Median follow up was 10 months. Complications included two seromas, one urinary tract infection, two cases of atelectasis and one prolonged ileus. There were no wound infections. The average postoperative length of stay was 7.8 days. There have been no mesh-related complications or recurrent hernias in our early postoperative follow-up period. The use of a new prosthetic device in infected or potentially infected fields, and the two-layered approach shows promising results. This is encouraging and provides an alternative approach for the management of difficult, recurrent hernias.

An 81-year-old man was admitted to our department due to acute ileus. He was diagnosed with sigmoid colon cancer with multiple metastatic lesions in the right lobe of the liver. Two weeks after insertion of an ileus tube, he underwent sigmoidectomy and permanent colostomy. The final diagnosis was stage IV sigmoid colon cancer with metastasis to the omentum. One month after the operation, adjuvant chemotherapy with oral administration of tegafur/uracil compound (UFT) and Leucovorin (LV), and drip venous infusion of irinotecan hydrochloride (CPT-11) was initiated (UFT 300 mg/day for 14 days, LV 75 mg/day for 14 days, CPT-11 90 mg/m(2) on the 1 st day, with 1 course consisting of 21 days). The levels of tumor markers, CA19-9 and CEA, and the size of metastases on CT were reduced remarkably after one and 4 courses of this therapy, respectively. Although the administration was temporarily discontinued due to low-grade nausea, we continued the treatment. Adjuvant chemotherapy with an oral administering agent is favorable for older patients with advanced colorectal cancer to reduce side effects and preserve the quality of life.
