The aim of our study was to assess our early and long-term results after stapled haemorrhoidopexy for fourth-degree haemorrhoids. 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. 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. 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.

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. 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. 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). 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.

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)-α-2a on the integrity of colonic anastomoses covered with fibrin glue when injected intraperitoneally immediately after colon resection. 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. 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). 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 FROM AUTHOR]

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 FROM AUTHOR]

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). Conclusions 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 FROM AUTHOR]

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 FROM AUTHOR]

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.

Background The aim of this experimental study was to evaluate the effects of steroid on colonic anastomosis in a rat model. Methods Forty female Wistar rats were randomised into two groups. After resection of a 1- cm segment of the transverse colon, an end-to-end sutured anastomosis was performed. In the rats of the control group 2 ml of solution 0.9% NaC1 was injected once daily intraperitoneally perioperatively. Rats of the steroid group received intraperitoneally once daily, and on the same penoperative days, hydrocortisone (5 mg/kg body weight in 2 ml solution NaC1). All the rats were sacrificed on the 8th postoperative day and the anastomoses were examined macroscopically. The bursting pressure measurements were recorded and anastomoses were graded histologically. Results Dehiscence rate was significantly higher in the steroid group than in the control group (p<0.001). Mean bursting pressure was significantly lower in the steroid group compared to the control group (p<0.001). Colonic healing process assessed as inflammatory cell infiltration and collagen deposition was significantly lower in the steroid group than in the control group (p<0.001, p=0.03 respectively). Conclusions Perioperative steroid treatment adversely affects healing of colonic anastomoses in the rat. [ABSTRACT FROM AUTHOR]

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 H
2 O-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.

Background To examine the role of TNM staging system as a predictive factor for postoperative morbidity and mortality, after colorectal cancer resections. Patients and methods During the last ten years, 368 patients with colorectal cancer were referred to our institution. All patients, who underwent primary treatment else- where or defunctioning colostomy only, or who did not undergo surgical therapy were excluded from the analysis. The early postoperative outcomes registration of the remaining 351 patients (197 men, median age 66.2 years) was retrospectively linked to TNM stage. Results TNM stage had a poor prognostic value for the early postoperative morbidity rate. In addition, according to the statistical analysis, the proportion of early postoperative mortality proved to be higher in patients with TNM stage III or IV colorectal cancer. Conclusions TNM classification could be considered as a reliable predictor of early postoperative mortality, but has no role in the prediction of early postoperative morbidity after colorectal resections.

Background The aim of this study is to underscore the incidence of synchronous polyps in patients with colorectal cancer and to emphasise the importance of their perioperative detection and management. Patients and methods Three hundred and seven patients underwent a potentially curative resection for colorectal cancer during the last ten years. A total of 129 synchronous polyps were detected in 72 of the patients (23.5%). Complete preoperative colonoscopy was performed in 62 of the patients. Forty- three polyps (3 3.4%) in 37 patients were removed preoperatively, while 69 polyps (5 3.4%) in 25 patients were included in the surgical specimen. In 10 patients the colon was evaluated postoperatively and 17 polyps (13.1%) were removed via endoscopy. Results A total of 81 polyps were detected in different surgical segments than the index cancer. Furthermore, 15 polyps were detected in the right colon of 55 patients with left colon cancer. Conclusions Synchronous polyps in patients with colorectal cancer are a frequent event. Thus, all patients should undergo a perioperative colonoscopy and endoscopic polypectomy, if feasible. The planned surgical procedure may alter as a consequence of the colonoscopic findings in some of the patients. [ABSTRACT FROM AUTHOR]

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. Method: 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 dud (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 FROM AUTHOR]

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 FROM AUTHOR]

PURPOSE: This study was conducted to investigate the incidence of free cancer cells in the peritoneal washings of patients who had undergone surgery for colorectal cancer and to evaluate its influence as a prognostic factor of the disease. METHODS: From 1990 to 1996, intraoperative washing cytology was performed in 110 patients who underwent surgery for colorectal cancer. All patients had curative resections. Immediately after the abdomen was opened and before exploration and mobilization of the tumor, 100 ml of saline was injected over the tumor site. Washings were then aspirated and taken for cytologic examination. RESULTS: Twenty-two (20 percent) of 110 patients examined were found to have positive cytology for intraperitoneal free malignant cells. The site of tumor in the colon or rectum, tumor size, nodal status, degree of differentiation, mucinous characteristics, and vascular or neural invasion were found not to affect the incidence of free cancer cells. Conversely, tumor penetration was found to affect the incidence of positive cytology. The degree of association among the stages of tumor penetration was indicated by the contingency coefficient, which was 0.42. Patients with positive cytology had a significantly higher rate of local recurrence and peritoneal carcinomatosis (22.8 vs. 8 percent, P = 0.05) than patients with negative cytology. Mortality rate was not found to be related to the presence of free cancer cells. CONCLUSION: Cytologic examination of peritoneal lavage at the time of surgery could be a useful prognostic indicator for local and peritoneal recurrence rate. However, it was not found to be a predictor of survival. [ABSTRACT FROM AUTHOR]

Abstract Objective To compare simultaneous application of sclerotherapy and rubber band ligation, with sclerotherapy and rubber band ligation applied separately for the treatment of 2nd degree haemorrhoids. Patients and methods Between 1993 and 1996, 255 patients that suffered from 2nd degree haemorrhoids were divided into 3 groups of 85 patients, each to receive either simultaneous sclerotherapy for smaller and rubber band ligation for larger piles (SCL/RBL) in one session, or sclerotherapy (SCL), or rubber band ligation (RBL), respectively. After a period of 4 years all patients were examined and their symptoms were recorded. Results The patients of the SCL group developed significantly fewer complications after treatment compared to the other two methods (P < 0.001), which did not differ from each other. After the SCL/RBL treatment, significantly more patients were symptom free (46%) than after SCL (8%), P < 0.001. There was no significant difference between the SCL/RBL (46%) and the RBL (31%) groups (P = 0.217), although the combined treatment seemed to be more effective than rubber band ligation. Only 10% of the patients of the SCL/RBL group needed additional sessions 6–24 months after the initial treatment compared to 30% of the patients of the SCL group (P = 0.001). However, there was no significant difference between SCL/RBL and RBL (17%) groups (P = 0.151). Conclusion The combination of sclerotherapy and rubber band ligation for treatment of 2nd degree haemorrhoids is significantly more efficient than sclerotherapy on its own. [ABSTRACT FROM AUTHOR]

- Abstract
The aim of our study was to determine the anastomotic leakage rate after the performance of low anterior resection without protective stoma. During the time period from 1989 to 2001, 82 consecutive patients underwent low anterior resection for rectal carcinoma without protective stoma. Thirteen anastomoses were hand sewn (15.8%) and the remaining 69 (84.2%) were constructed with the use of a circular stapling gun. The mean distance of the anastomoses from the anal margin was 6.2 cm (range, 3–9 cm). None of the 82 low anterior resections was covered by a defunctioning stoma. Clinical anastomotic leakage occurred in 4 patients (4.9%) and 4 other patients presented radiologically detected leakage (4.9%). No death occurred in the 8 patients that presented anastomotic dehiscence. Non-specific complications were detected in 11 (13.4%) of 82 patients. In conclusion, the low leakage rate of the anastomoses in our patients allows us to recommend low anterior resection without defunctioning stoma. [ABSTRACT FROM AUTHOR]

- Abstract
The aim of the present study was to evaluate the effect of glue tissue on the healing of colonic anastomosis in rats. Two groups of 20 Wistar rats each were used. Following laparotomy, a segment of 1 cm of the colon was resected, 10 cm from the ileocecal valve. In the control group, the anastomosis was sutured in a single layer with 6-0 polypropylene interrupted extramucosal sutures. In the glue group, the anastomosis was performed by using 2-octyl cyanoacrylate (Dermabond, Ethicon). Rats were sacrificed on day 7 following operation. Integrity of the anastomoses, existence of perianastomotic abscess or peritonitis, and adhesion formation were recorded. Anastomoses were resected including a 2.5-cm of bowel on either side. Bursting pressures were measured and the specimens were sent for histological examination. Anastomotic dehiscence occured in 20% of the animals in each group. Adhesion formation was more extensive in the glue group compared to the control group, but this difference was not statistically significant ( p=0.074). Bursting pressures of the anastomoses between the two groups were not statistically significant ( p=0.897). The wound healing process, as assessed by inflammatory cell infiltration, blood vessel neodevelopment, collagen deposition and fibroblast activity, did not differ statistically between the two groups ( p>0.05). In conclusion, 2-octyl cyanoacrylate provides, under experimental conditions, a sutureless anastomosis equal in healing to the conventionally sutured one. The outcome may differ under demanding clinical situations. [ABSTRACT FROM AUTHOR]

Objective: To compare stapled haemorrhoidectomy with Milligan-Morgan haemorrhoidectomy. Design: Prospective open study. Setting: Teaching hospital, Greece. Patients: 85 patients with prolapsing haemorrhoids were invited to choose between stapled and Milligan-Morgan haemorrhoidectomy. 48 chose the former and 37 the latter. Interventions: Operation. Postoperatively, the patients were given analgesics on demand, and were discharged as soon as their condition and particularly their pain had improved. Main outcome measures: Patients' symptoms and their opinion about the procedures, which were recorded during their follow-up which lasted for 6 months. Results: Stapling resulted in a significantly shorter operating time, and less postoperative pain and other symptoms, than Milligan-Morgan excision (p < 0.001). Postoperative complications, and mean time in hospital did not differ significantly between the two groups. During the follow-up period there was no significant difference in the incidence of recurrences between the two groups. Six months after the operation, significantly more patients in the stapled group had residual skin tagsexternal haemorrhoids than in the Milligan-Morgan group, and all these patients had fourth degree haemorrhoids. Conclusions: Stapled haemorrhoidectomy is a promising method of treatment for prolapsing third degree haemorrhoids. Its effectiveness is questionable for fourth degree ones. Initially, the results are as good as after Milligan-Morgan haemorrhoidectomy, especially for third degree haemorrhoids. However, more patients and longer follow-up periods are required for its long-term efficacy to be confirmed. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Bile leakage after laparoscopic biliary surgery is a surgical challenge in which endoscopy can play an important role.Methods: A total of 26 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) in our department. Patients with evidence of major ductal injury were treated surgically. In all other cases, endoscopic sphincterotomy was performed, any retained bile duct stones were removed, and a biliary endoprosthesis or a nasobiliary catheter was inserted on a selective basis.Results: ERCP was successful in 24 patients. Seven patients were treated surgically after cholangiography revealed major ductal injury. Two more patients were eventually operated on due to bile peritonitis. Of the other 15 patients, 11 had leakage from the cystic duct and four had leakage from the gallbladder bed. Bile duct stones were removed from eight patients, an endoprosthesis were inserted in five patients, and a nasobiliary catheter was inserted in two patients. Bile leakage was treated successfully in all 15 patients with no further complications.Conclusion: ERCP is a means of safe diagnosing the cause of a bile leakage and offers a definitive treatment in most cases.

Purpose: Lanreotide, a long-acting somatostatin analogue, inhibits intestinal, bile and pancreatic secretions and decreases intestinal motility. The purpose of this experimental study was to evaluate the effects of lanreotide on the healing of intestinal anastomoses following small bowel obstruction. Methods: Two groups of 16 Wistar rats (average weight 310 g) were used. Basal diameters of ileus were measured prior to the ligation of the bowel, 15 cm from the ileocecal valve. Luminal fluid was also withdrawn proximal to the obstructed bowel for sodium and potassium analysis. Lanreotide was administered intramuscularly in a single dose (5.4 mg/kg) in the first group, while the same volume of saline was used in the control group. 48 h later rats were re-operated upon. Diameters of the obstructed segments were measured, and luminal fluid of the obstructed bowel was withdrawn and sodium and potassium levels were measured. A segment of 1 cm of the obstructed bowel was resected and end-to-end intestinal anastomosis was performed. Rats were sacrificed on day 7 following the second operation. Anastomoses were examined macroscopically and resected including a 2.5 cm of small bowel on either side. Bursting pressures were measured and the specimens were send for histological examination. Results: The diameter of obstructed bowel increased significantly in both groups. The increase was more prominent in the control group (P < 0.001). Total luminal electrolyte contents for sodium and potassium were stastistically higher in the control group compared to the lanreotide group (P < 0.001). Adhesion formation was more extensive in the control group. Bursting pressures were significantly higher in the lanreotide group compared to the control group (P =0.003). Histological examination of anastomoses showed a more profound inflammatory reaction in the control group compared to the lanreotide group while microscopical healing of the anastomoses was almost the same in both group...

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.

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 FROM AUTHOR]

Background The aim of our study is to present our experience in the treatment of liver metastases in patients with colorectal cancer. Patients and methods Between 1997 and 2003 a total of 12 patients with liver metastases from a primary colorectal cancer were treated in our department. They were 8 males and 4 females with a median age of 64 years (range 56-70 years). Results Ten patients underwent liver resection. The surgical procedures were 4 major hepatectomies (3 right hepatectomies, 1 left lobectomy) and 9 wedge liver resections. In total, 16 metastatic lesions were resected. Already at the time of the primary tumour, 5 patients presented with a synchronous liver metastasis. In 3 of them, liver metastasis was resect- ed together with the primary tumour, and in the rest, resection was performed 1 month after the initial operation. In S patients liver metastases were metachronous and were diagnosed 3-14 months after the initial operation. The median survival of the patients was 39 months. Two patients (one with 2 metastatic lesions) underwent radiofrequency ablation (RFA) of the metachronous metastatic lesions and remain well 3-6 months postoperatively. Conclusions Hepatectomy is the treatment of choice for hepatic metastasis of colorectal cancer, whenever feasible. Recent promising treatments such as RFA can further improve the outcome of these patients. [ABSTRACT FROM AUTHOR]

Background The aim of this study was to define the survival rates in patients with rectal carcinoma treated with curative resections. Patients and methods Between 1993 and 1998, 54 patients with rectal cancer underwent curative resection by conventional technique. Tumour location, TNM staging and tumour differentiation were evaluated. Among the 54 patients, 14 under- went high anterior resection, 28 low anterior resection, 7 abdominoperineal resection and 5 underwent local excision. Survival rates were calculated using the Kaplan- Meier method and long-range analysis. Results Five-year survival was 70.4%. The survival rate statistically significantly decreased with increasing TNM tumour stage (p=0.009). Patients with poor differentiation of the tumour had the lowest 5-year survival (33%) compared to patients with moderate (72%) and good (78%) tumour differentiation. Sex and age did not affect survival. Location of the tumour in the distal end of the rectum and mucinous characteristics are poor prognostic factors affecting survival. Conclusions Curative resection combined with chemoradiotherapy, whenever necessary, is accompanied with acceptable 5-year survival rates. [ABSTRACT FROM AUTHOR]

Parastomal hernia is the most frequent complication of colostomy. Many surgical techniques have been postulated and prosthetic surgery seems to represents the first-choice treatment. The aim of this study is to report the surgical treatment of 4 patients that developed parastomal hernia, 3-10 months after abdominoperineal excision of the rectum and permanent sigmoidostomy due to carcinoma of the rectum. The repair was made with the use of polypropylene mesh extraperitoneally. One case of limited skin necrosis occurred without any serious consequences. No recurrence has been recorded among the patients, up to this day (follow-up period: 36 months). In conclusion, the suturing of fascial defect and the use of polypropylene mesh extraperitoneally is effective in the treatment of parastomal hernia. [ABSTRACT FROM AUTHOR]

Background The purpose of this study was to evaluate the 5-year survival of patients with colon adenocarcinoma that underwent elective or emergency curative surgical treatment. Patients and methods Between 1993 and 1998, 80 patients underwent a potentially curative colonic resection based on mobilisation along anatomic planes. Among the patients, 26 underwent right colectomy, 3 transverse colectomy, 13 left colectomy and 38 sigmoidectomy. All patients classified as TNM stage III underwent adjuvant chemotherapy. The Kaplan-Meier method was used to analyse survival. Results Overall 5- year survival was 69.5%. Patient's sex and age, mucinous characteristics of the tumour and tumour location did not significantly affect survival. Patients with higher Duke's classification and TNM stage had significantly worse 5- year survival (p=0.025 and p=0.007, respectively). Although patients with good tumour differentiation had the highest 5-year survival, this difference was not statistically significant (p=0.211). Conclusions The treatment of colon adenocarcinoma with curative resection by the end of the 20th century is accompanied with acceptable rates of overall 5-year survival. [ABSTRACT FROM AUTHOR]

Background The aim of this study is to determine the age-associated prognosis in patients who underwent curative resection for colorectal cancer. Patients and methods Between 1993 and 1999, a total of 136 patients underwent curative surgical procedures for colorectal cancer. The study population was divided into three groups according to the age of the patients. Group A: patients younger than 45 years, group B: patients between 45 and 75 years and group C: patients older than 75 years. Tumour location, Dukes' staging, tumour differentiation and five-year survival were evaluated. Results There was no significant association between age and tumour staging or tumour differentiation (p=0.990, p=0.7S3 and p=0308, respectively). The overall survival at 5 years was 85.7% for the young patients, 77.5% for the middle-aged patients and 62.5% for the elderly patients. Conclusions This aged-grouped study indicates that prognosis is comparable between younger and middle- aged patients whereas in elderly patients it is worsening but not statistically significantly.

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, 9 1.9% 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 !oca! 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 !oca! re!apse during the last few years. [ABSTRACT FROM AUTHOR]

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 FROM AUTHOR]

Patients and methods During the last ten years, 93 patients underwent anterior resection of the rectum for rectal cancer. Low anterior resection with total mesorectal excision (TME) was performed in 72, and high anterior resection in 21 patients. The definition of the anastomotic leakage was based on clinical features, peripheral blood investigations and abdominal CT scan. Results Clinically apparent anastomotic leakage developed in 9 patients (9.7%). Four patients were managed conservatively and five operatively. Postoperative mortality among the patients with anastomotic leakage was not recorded. Conclusions The incidence of anastomotic leakage after anterior resection of the rectum for rectal cancer is relatively low. It remains however the most serious complication following rectal resection for cancer. [ABSTRACT FROM AUTHOR]

Background The purpose of this study is to present the incidence of anastomotic leakage after colon resection and intraperitoneal anastomosis for colorectal cancer. Patients and methods In the last ten years, 205 patients underwent colonic resection with intraperitoneal anastomosis for colon cancer. The surgical management of colorectal cancer consisted of 66 right hemicolectomies, 3 transverse colectomies, 17 left hemicolectomies, 98 sigmoid colectomies and 21 high anterior resections of the rectum. Diagnosis of leakage was made by clinical features, blood vessel examinations and abdominal CT-scans. Results Anastomotic leakage occurred in S out of 205 patients (2.4%). One of these patients underwent emergency surgery and the other 4 elective surgery; 3 by manual, 2 by mechanical suture. Three patients with anastomotic leakage were re- operated on days 4, 5 and 7, and 2 patients were treated conservatively. Two of the patients (20%) with anastomotic leakage died due to sepsis. Conclusions Even though the rate of anastomotic leakage in patients with intraperitoneal anastomosis after colon resection for colorectal cancer is low, it remains a significant complication and a major cause of postoperative morbidity and mortality.

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 FROM AUTHOR]

Background:. This study was aimed at examining whether the addition of fibrin glue to a sutured colonic anastomosis improves its healing or not. Methods:. We studied the effect of adding fibrin glue on a sutured colonic anastomosis. Thirty-six Wistar rats were randomized into two groups of 18 rats each. A sutured anastomosis was performed in all rats. Fibrin glue was applied around the anastomosis of the rats of group B. Rats were sacrificed on the eighth postoperative day. Results:. The rate of anastomotic leakage was found not to be significantly different between the two groups. The mean bursting pressure of the colonic anastomoses was significantly higher in group B (fibrin-treated) than in group A. Conclusion:. Fibrin glue application around a sutured anastomosis provides a safer anastomosis which is stronger than the sutured one. [ABSTRACT FROM AUTHOR]

- Abstract
Perineal endometriosis, especially with anal sphincter invasion, is a rare occurrence. We present a patient with perineal endometriosis in an episiotomy scar with anal sphincter involvement. The endometriotic mass was completely excised under general anesthesia with portions of the episiotomy scar and external anal sphincter. The procedure was followed by overlapping sphincter reconstruction. The excised mass was sent for microscopic examination, which confirmed endometriosis. The postoperative course was without complications. One year after the operation, the woman is asymptomatic and fully continent. Complete excision including a part of the anal sphincter with primary sphincteroplasty is the best treatment for perineal endometriosis involving the anal sphincter. [ABSTRACT FROM AUTHOR]
