ABSTRACT

BACKGROUND/AIMS: Randomized Swedish studies demonstrate the efficacy of a 5-fraction course of preoperative radiotherapy for rectal carcinoma. The present study evaluates the results in a single Greek institution over a 10-year period, with a similar regimen. METHODOLOGY: During the period of 1995-2000, 150 consecutive patients with Dukes' B or C rectal cancer were matched to receive preoperative radiotherapy (Group I) or not (Group II). Seventy-five patients received pelvic radiotherapy of 2500cGY/5 fractions, followed by surgery within one week. Radiotherapy was delivered through 4 portals, with the patient lying in the prone position. A CT scan was used to define treatment volume. The 5-fraction course was used for lesions that seemed readily resectable. Patients in both groups received adjuvant chemotherapy. Local recurrence, disease-free interval and 5-year survival were evaluated and analyzed. RESULTS: The disease-free interval was significantly longer in Group I (p < 0.0005). This benefit was mainly due to a significantly lower incidence of local recurrence in Group I (9/75, 12%) compared with Group II (30/75, 40%) (p < 0.0005). The incidence of distant metastases was not significantly different between the 2 groups. The 5-year survival for all patients, who underwent "curative" surgery was significantly higher in Group I (77.3%) as compared to Group II (39%), (p < 0.0005). CONCLUSIONS: Patients with resectable rectal cancer who received 2500cGy/5 fractions preoperative radiotherapy to the pelvis had excellent local control of disease, longer disease-free interval and higher 5-year survival than patients who did not. These patients were able to undergo sphincter preserving surgery and adjuvant chemotherapy.

ABSTRACT

AIM: The aim of this study was to investigate whether iloprost injected intraperitoneally immediately after colon resection can improve anastomotic healing on the fifth and eighth postoperative days. METHODS: Forty Wistar rats were randomised into 2 equal groups. After the resection of a 1 cm segment of transverse colon, an end to end sutured anastomosis was generated. From the day of the operation, group 1 (control) received intraperitoneal 3 cc saline solution once daily until sacrifice, while group 2 (iloprost) received iloprost in a dose of 2 mg/kg body weight intraperitoneally once daily until sacrifice. Each group was further randomly divided into 2 equal subgroups and animals were sacrificed on the fifth (subgroup A), and eighth (subgroup B) postoperative days. After sacrifice, anastomoses were examined macroscopically and were measured for bursting pressures and tissue hydroxyproline levels while anastomotic healing process was evaluated histopathologically. RESULTS: None of the rats exhibited any clinical evidence of leakage and there were no instances of peri-anastomotic abscess or peritonitis. Bursting pressure on the fifth postoperative day was significantly higher in the iloprost group than in the control group (P<0.001), while on the eighth postoperative day, bursting pressure was higher in the iloprost group but not significantly different (P=0.165). On both the fifth and eighth postoperative days rats in the iloprost group developed significantly more marked neo-angiogenesis and, in parallel with this, there was a trend showing a higher inflammatory cell infiltration. CONCLUSION: The intraperitoneal administration of iloprost promoted neo-angiogenesis and enhanced colonic healing on the fifth postoperative day.

ABSTRACT

BACKGROUND: The aim of our study was to assess our early and long-term results after stapled haemorrhoidopexy for fourth-degree haemorrhoids. METHODS: Our study covers the time period from 1998 to 2002 and consists of 56 consecutive patients (33 men) with fourthdegree haemorrhoids who underwent stapled haemorrhoidopexy. RESULTS: During the postoperative period, 6 patients (10.7%) experienced pain for 7-14 days, which was treated with oral analgesia. Ten patients (17.8%) experienced gas incontinence and two of them also reported soiling. The incontinence subsided within 3-8 weeks. Median follow-up was 72.1 months (range, 55-86 months). Recurrence of the haemorrhoidal disease occurred in 33 patients (58.9%). The overall reintervention rate was 42.8%, as 24 patients required excisional haemorrhoidectomy by the Milligan-Morgan technique at a later stage. CONCLUSIONS: Stapled haemorrhoidopexy seems to be a safe, low-pain but ineffective technique for the treatment of fourth-degree haemorrhoids, as it is accompanied by high recurrence and reintervention rates in the long term.

ABSTRACT

PURPOSE: This experimental study was designed to investigate whether iloprost can reverse impaired colonic healing caused by immediate postoperative intraperitoneal administration of 5-fluorouracil plus leucovorin. METHODS: Eighty Wistar rats were randomized into four groups. After resection of a 1-cm segment of transverse colon, an end-to-end sutured anastomosis was generated. Rats received saline solution (Group 1), 5-fluorouracil plus leucovorin (Group 2), iloprost (Group 3), and 5-fluorouracil plus leucovorin plus iloprost (Group 4) intraperitoneally from the day of operation and once daily until killing. Each group was further randomized into two subgroups. Subjects were killed on the fifth (Subgroup a) and eighth (Subgroup b) postoperative days. After killing, anastomoses were examined macroscopically and graded histologically. Rats were measured for anastomotic bursting pressures and tissue hydroxyproline levels. RESULTS: The leakage rate of the anastomoses was significantly higher in the 5-fluorouracil plus leucovorin group compared with the other groups (P = 0.049). Bursting pressure was significantly lower in 2a subgroup (5-fluorouracil plus leucovorin, postoperative Day 5) than in 4a (5-fluorouracil plus leucovorin plus iloprost, postoperative Day 5; P < 0.001). Adhesion formation was significantly higher in all b subgroups compared with the Control b subgroup. Neoangiogenesis was significantly higher in iloprost and iloprost plus 5-fluorouracil plus leucovorin subgroups compared with the 5-fluorouracil plus leucovorin subgroups. Hydroxyproline levels, collagen deposition, fibroblasts, and white cell count were significantly higher in the iloprost plus 5-fluorouracil plus leucovorin b subgroup (postoperative Day 8) compared with the 5-fluorouracil plus leucovorin b subgroup (postoperative Day 8). CONCLUSIONS: The immediate postoperative, intraperitoneal administration of iloprost counteracts and reverses the negative effects of 5-fluorouracil plus leucovorin chemotherapy and protects colonic healing in rats.

ABSTRACT

BACKGROUND: It has been well established that the immediate postoperative intraperitoneal administration of chemotherapeutic agents such as 5-fluorouracil (5-FU) after curative colon resection for colon cancer destroys disseminated cancer cells and inhibits micrometastases but also inhibits anastomotic healing. On the other hand, the application of fibrin glue constitutes a physical barrier around the anastomosis and may prevent anastomotic leakage. The purpose of this experimental study was to determine the effect of 5-FU plus interferon (IFN)-alpha-2a on the integrity of colonic anastomoses covered with fibrin glue when injected intraperitoneally immediately after colon resection. MATERIALS AND METHODS: Sixty rats were randomized to one of four groups. After resection of a 1-cm segment of the transverse colon, an end-to-end sutured anastomosis was performed. Rats of the control and the fibrin glue groups were injected with 6 ml of 0.9% sodium chloride (NaCl) solution intraperitoneally. Rats in the 5-FU + IFN and the 5-FU + IFN + fibrin glue groups received 5-FU plus IFN intraperitoneally. The colonic anastomoses of the rats in the fibrin glue and in the 5-FU + IFN + fibrin glue groups were covered with fibrin glue. All rats were sacrificed on the 8th postoperative day, and the anastomoses were examined macroscopically. The bursting pressure measurements were recorded, and the anastomoses were graded histologically. RESULTS: Only the 5-FU + IFN group had anastomoses rupture, and the rupture rate (33%) in this group was significantly greater than in the other groups, where there were no ruptures (P = 0.015). The adhesion formations score was, on average, significantly higher in rats of the 5-FU + IFN group compared with the control group (P = 0.006) and the 5-FU + IFN + fibrin glue group (P = 0.010). Bursting pressures were significantly lower in the control group when compared to the fibrin glue and 5-FU + IFN + fibrin glue group (P < 0.001). Rats in the 5-FU + IFN + fibrin glue group developed significantly more marked neoangiogenesis than rats in the other groups. Inflammatory cell infiltration, collagen deposition, and fibroblast activity did not differ significantly among the four groups (P = 0.856, P = 0.192 and P = 0.243, respectively). CONCLUSION: The immediate postoperative intraperitoneal administration of 5-FU plus IFN impairs colonic healing. However, when the colonic anastomoses were covered with fibrin glue, the injection of 5-FU plus IFN had no adverse effects on the integrity of the anastomoses.

ABSTRACT

PURPOSE: This study was designed to investigate whether intraperitoneally injected insulin-like growth factor I is able to protect colonic healing from the adverse effects of hydrocortisone therapy. METHODS: Eighty female Wistar rats were randomized into four groups (20 rats each). After resection of a segment of transverse colon, an end-to-end anastomosis was performed. Hydrocortisone (5 mg/kg body weight) was injected intramuscularly in rats of cortisone (Group B) and insulin-like growth factor I + cortisone (Group D) groups once daily for seven days before and after the operation. Insulin-like growth factor I (2 mg/kg body weight) was intraperitoneally injected in rats of the insulin-like growth factor I (Group C) and the insulin-like growth factor I + Cortisone (Group D) groups immediately after operation and on the second, fourth, and sixth postoperative days. Rats were killed on the seventh postoperative day. Anastomoses were graded macroscopically and histologically, and bursting pressures and anastomotic hydroxyproline levels were recorded. Statistical analyses were performed by using Fisher's exact test for the comparison of proportions and ANOVA for the comparison of means among groups with subsequent post-hoc analysis using Bonferroni correction. RESULTS: Leakage rate was significantly higher in the cortisone (Group B) group. Bursting pressures were significantly lower in the cortisone group, whereas they were significantly higher in the insulin-like growth factor I and insulin-like growth factor I + cortisone groups (Group C and D). Histology revealed a significant decrease of inflammatory cell infiltration, neoangiogenesis, and fibroblast activity in the cortisone group compared with the control group, whereas these parameters were significantly higher in the insulin-like growth factor I and insulin-like growth factor I + cortisone groups. Hydroxyproline levels were significantly higher in the insulin-like growth factor I and insulin-like growth factor I + cortisone groups. CONCLUSIONS: Hydrocortisone inhibits the healing of colonic anastomoses. However, insulin-like growth factor I given intraperitoneally mediates the deleterious effects of cortisone and protects colonic healing in rats.

ABSTRACT

BACKGROUND: After colon resection for colonic cancer, the administration of antineoplastic agents may prolong survival by killing residual cancer calls and preventing metastasis, but may also slow anastomotic healing. This study was designed to determine the effects of 5-fluorouracil (5-FU) and leucovorin (LEV), injected intraperitoneally, on the healing of colonic anastomoses with or without fibrin glue (FG) covering. METHODS: Sixty rats were randomized to one of four groups. After resection of a transverse colon segment, an end-to-end sutured anastomosis was performed. Rats in the 5-FU+LEV and the 5- FU+LEV+FG groups received 5-FU+LEV intraperitoneally. The colonic anastomoses of the rats in the FG group and in the 5-FU+LEV+FG group were covered with fibrin glue. All rats were killed on postoperative day 8. Bursting pressure measurements were recorded and the anastomoses were examined macroscopically and histologically. RESULTS: The leakage rate of the anastomoses was significantly different among groups. Specifically, the leakage rate was significantly higher in the 5-FU+LEV group (40%) than in the FG and in the 5-FU+LEV+FG groups where there were no leakages (p=0.017). The mean adhesion formation score was significantly higher in rats of the 5-FU+LEV group, compared to the control (p=0.023), the FG (p=0.006) and the 5-FU+LEV+FG (p=0.006) groups. Bursting pressures were significantly lower in the 5-FU+LEV group than in the other groups (p<0.001). Also, bursting pressures were significantly lower in the control group compared to the FG and 5-FU+LEV+FG groups (p<0.001). Rats in the 5-FU+LEV+FG group had significantly greater neoangiogenesis and fibroblast activity than those in the 5-FU+LEV group (p=0.025). CONCLUSION: The early intraperitoneal postoperative administration of 5-fluorouracil plus leucovorin impaired colonic wound healing. However, the application of fibrin glue prevented the deleterious effect of chemotherapy.

ABSTRACT

OBJECTIVE: The aims of this prospective study were to determine carcinoembryonic antigen (CEA) levels and incidence of cytology in peritoneal washings of patients with colorectal cancer, correlate the results with various histopathological factors and determine their significance as prognostic factors of the disease. METHODS: From 1992 to 1999, 98 patients with adenocarcinoma of the colon or intraperitoneal rectum underwent curative surgery and enrolled in this study. RESULTS: Overall, 25 (26.3%) of 95 patients were found to have positive cytology. The proportion of patients with positive cytology was higher in the recurrence group (36.4%) than in the groups of 5-year survival and hepatic metastases (24.6% and 26.3%, respectively), but this difference was not significant. The 5-year survival group had the lowest peritoneal CEA levels compared with the other groups, but this difference was not significant. Peritoneal cytology and CEA level alone were not sensitive, specific or accurate enough indicators in predicting survival, hepatic metastases or local recurrence. The analysis of patients with positive cytology and high peritoneal CEA level revealed that their combination can predict local recurrence with accuracy of 85%. CONCLUSIONS: The presence of free malignant cells, as detected by cytology and CEA level, in the peritoneal cavity of patients with resectable colorectal cancer had no detectable impact on survival, hepatic metastases or local recurrence rate. However, local recurrence can be predicted with accuracy of 85% in patients who have positive cytology and high peritoneal CEA level at the same time.

ABSTRACT

In its more severe form heparin induced thrombocytopenia (HIT) is a rare immune mediated complication of heparin administration that potentially has catastrophic results, and significant mortality. In view of the severity of this condition it is important for the clinician to maintain a high index of suspicion and get alerted to the HIT syndrome by the precocity of platelet count decrease in any patient group, and especially in those previously exposed to heparin. We report on a 72-year-old woman who developed HIT syndrome that was complicated by recurrent arterial thromboses after receiving postoperative antithrombotic prophylaxis with tinzaparin, a low molecular weight heparin. The patient was successfully treated with iloprost (Ilomedin, iloprost tromethamine, Schering) a stable prostacyclin analogue, at the acute phase of the syndrome, followed by long-term treatment with clopidogrel (Plavix, clopidogrel bisulfate, Sanofi) an inhibitor of adenosine diphosphate (ADP) receptor. Although direct thrombin inhibitors have been proven to be effective for the treatment of HIT thrombosis, they do not completely eliminate the morbidity and mortality of this disorder. Our case report suggests that antithrombotic treatment by targeting of the activated platelets with a potent platelet inhibitor during the acute phase of type II HIT syndrome followed by long-term administration of oral anticoagulation may be an additional, safe and effective therapeutic alternative that merits to be systematically studied.

ABSTRACT

BACKGROUND: Stapled haemorrhoidopexy (SH) is associated with low postoperative pain but, when performed for advanced piles, carries high recurrence rates. The aim of our study was to assess our long-term results after SH for third-degree haemorrhoids. METHODS: A total of 126 consecutive patients (67 men and 59 women) with third-degree haemorrhoids underwent SH in our unit between 1998 and 2002. Of these, 120 (95.2%) were followed up in the outpatient department after a median interval of 61.5 months (range, 38-84 months). RESULTS: During the postoperative period, 7 patients (5.8%) experienced pain for 5-12 days, which was treated with oral analgesia. Seven patients (5.8%) experienced gas incontinence and one of them also reported soiling; the incontinence subsided within 2-8 weeks. Recurrence of the haemorrhoidal disease occurred in 8 patients (6.6%). CONCLUSIONS: SH is a safe, low-pain and, in the long-term, effective technique for the treatment of third-degree haemorrhoids.

ABSTRACT

BACKGROUND: The Muir-Torre syndrome is a rare autosomal dominant condition and is currently considered a subtype of the more common hereditary nonpolyposis colorectal cancer syndrome, in which multiple primary malignancies occur together with sebaceous gland tumors. CASE PRESENTATION: We describe a case of a 62-year-old woman with three primary colorectal tumors, genital tumor, and sebaceous adenomas and present her family history of three generations. Our case represents the first case reported from Greece in the international literature. CONCLUSION: Recognition of the syndrome in patients with sebaceous gland tumors should facilitate early detection of subsequent malignancies if the patient is entered into appropriate screening programs.

ABSTRACT

The aim of this prospective study is to describe the combined technique and results of stapled haemorrhoidopexy and lateral internal sphincterotomy for patients suffering from prolapsing 3rd-degree haemorrhoids and chronic fissure-in-ano. During the period from 1999 to 2004, 26 patients underwent combined surgical treatment for anal fissure and prolapsing symptomatic haemorrhoids. Preoperative and postoperative clinical evaluation and the patient's degree of satisfaction were recorded. Early complications included faecal urgency (3 patients) and pain (2 patients). Complete continence was restored within 10 weeks in all patients except 1 who had persisting incontinence to flatus. All fissures healed completely within 4 weeks. No haemorrhoidal or fissure recurrence has been observed during follow-up. The combination of stapled haemorrhoidopexy and lateral internal sphincterotomy is a safe and effective procedure for the treatment of prolapsing 3rd-degree haemorrhoids and chronic anal fissures.

ABSTRACT

We report on a case of a 68-year-old man who was transferred to our department to undergo surgical treatment of intestinal obstruction and a palpable right sided abdominal mass. The abdominal computed tomography scan revealed a small bowel obstruction with an incarcerated spigelian hernia. A mesh repair was performed by suturing the mesh to the internal oblique muscle and to the rectus sheath. The postoperative course was uneventful, and no recurrence has occurred during the 2-year follow-up. An urgent operation should be performed as soon as an accurate diagnosis of incarcerated spigelian hernia has been made. Computed tomography should be helpful in order to establish an accurate diagnosis of the incarcerated hernia.

ABSTRACT

PURPOSE: The aim of this experimental study was to investigate whether covering the colonic anastomoses with fibrin glue can protect the colonic healing from the adverse effects of 5-fluorouracil (5-FU), when it is injected intraperitoneally immediately after colon resection. METHODS: Sixty-four rats were randomized to one of four groups. After resection of a 1-cm segment of the transverse colon, an end-to-end sutured anastomosis was performed. Rats of the control group and the fibrin glue group were injected with 6 ml of solution 0.9 percent NaCl intraperitoneally. Rats in the 5-FU and the 5-FU + fibrin glue groups received 5-FU intraperitoneally. The colonic anastomoses of the rats in the fibrin glue group and in the 5-FU + fibrin glue group were covered with fibrin glue. All rats were killed on the 8th postoperative day and the anastomoses were examined macroscopically. The bursting pressure measurements were recorded and the anastomoses were graded histologically. RESULTS: The leakage rate of the anastomoses was significantly higher in the rats of the 5-FU group than in those of the fibrin glue group and those of the 5-FU + fibrin glue group (37.5 percent vs. 0 percent, P = 0.020). The adhesion formation score was significantly higher in rats of the 5-FU group than in the other groups. Bursting pressures were also significantly lower in the 5-FUgroup than in the other groups ( P < 0.001). Rats in the 5-FU + fibrin glue group developed significantly more marked neoagiogenesis than rats in the other groups. Rats in the 5-FU + fibrin glue group also presented significantly more fibroblast activity than those in the 5-FU group. ( P = 0.004) CONCLUSIONS: The immediate postoperative, intraperitoneal administration of 5-FU inhibited wound healing. However, when the colonic anastomoses were covered with fibrin glue, the injection of 5-FU had no adverse effects on the healing of the anastomoses.

ABSTRACT

BACKGROUND: Endoscopic sphincterotomy (ES) is widely used for the treatment of residual bile duct stones in patients who had common bile duct (CBD) exploration and T-tube insertion. METHODS: In a 4-year period 45 patients were referred for endoscopic removal of residual bile duct stones. All patients had been operated 7-15 days earlier for choledocholithiasis and had a T-tube in the common bile duct (CBD). RESULTS: Four patients were excluded. Three patients had a periampullary carcinoma and the fourth patient had no residual stone seen at cholangiography. All patients had a successful ES, conventional in 34, precut-knife in 3, and with the rendezvous technique in 4 patients. In 24 patients, all having stones distal to the T-tube, complete clearance of the CBD was achieved during one session and the T-tube was removed after 48 h. In the remaining 17 patients (15 having stones proximal to the T-tube), the T-tube had to be removed first and following stone extraction, a plastic stent was inserted in the CBD. Complete bile duct clearance and stent removal was achieved in a second session 3-4 weeks later. There were no serious complications or biliary related symptoms after the procedures and after a mean follow-up period of 18 months. CONCLUSION: The endoscopic technique is safe and efficient for the treatment of residual stones after CBD exploration with a T-tube insertion, offering immediate cure compared to the percutaneous techniques. It is also an ideal method for the diagnosis of periampullary carcinomas.

ABSTRACT

Stapling procedure is a new technique for the surgical management of prolapsing haemorrhoids. Some articles have reported severe adverse effects of this operation. We describe a case of an excessive staple-line stenosis followed stapled haemorrhoidopexy. Proctoscopic dilatation resulted in complications of retropneumoperitoneum, pneumomediastinum, subcutaneous emphysema and perianal abscess. Drainage of the abscess was performed, allowing quick recovery. After discharge from the hospital, the patient continued to perform periodic dilatation. Simple proctoscopic dilatation was conducted in an outpatient setting.

ABSTRACT

We present a 60-year-old man with a metastatic subcutaneous lump in the left lower quadrant of the abdomen, from rectal cancer, which was treated three years earlier with low anterior resection of the rectum. Excision of the abdominal wall metastasis was accomplished with negative histological margins, but six months later a new abdominal wall mass was detected. The patient underwent surgery again, in which the abdominal wall metastasis was resected en bloc with adherent portion of small bowel, along with inguinal lymph node dissection. The patient's condition deteriorated 10 months after the initial diagnosis, presenting again with abdominal wall cancer and dying from disseminated peritoneal disease.

ABSTRACT

BACKGROUND: The aim of our study is to present the preliminary results of an ongoing radio-frequency (RF) ablation study in patients with hepatic metastases from colorectal cancer. PATIENTS AND METHODS: From November 2003, two patients affected with metachronous liver metastases from colorectal cancer were treated with RF ablation. The mean age of the patients was 66 years (58 and 74 years). Tumours were unifocal right-lobe lesions in one patient and bifocal in the second patient. Under general anaesthesia, a Radionics 200-W RF generator was used to ablate lesions with H2O-cooled electrodes via laparotomy. Patients' follow-up ranged from two to five months including evaluation of salient clinical, radiological and laboratory parameters. RESULTS: The patients experienced moderate-to-severe pain in the right abdomen lasting for 2-3 days and mild fever for 3-6 days after treatment. During the follow-up period no local recurrence was observed. CONCLUSIONS: RF ablation emerges to be a promising method for the treatment of hepatic metastases from colorectal cancer.

ABSTRACT

BACKGROUND: To determine the incidence of local recurrence, after curative resection for rectal cancer, with the application of total mesorectal excision (TME). PATIENTS AND METHODS: During the last ten years, 120 patients underwent curative resection for rectal cancer. As a rule, except for the cases that underwent high anterior resection, TME was applied. In terms of local relapse, routine TME, preoperative radiotherapy, tumour's stage, differentiation grade and number of positive nodes were taken into account. RESULTS: Eight patients (6.7%) presented with local relapse. At 5 years, 91.9% of patients were free of local recurrence and the actuarial disease-free survival was 81%. A significant association between routine TME, tumour's stage, differentiation grade, lymph node invasion and local recurrence was observed. Conversely, preoperative radiotherapy appeared to play no protective role. CONCLUSIONS: The curative resection of rectal cancer, with the application of TME, has led to a very low incidence of local relapse during the last few years.
