Infarcted ligamentum teres hepatis lipoma mimicking acute abdomen in a female patient: a case report and mini-review of the literature.

Lipomas of the ligamentum teres hepatis are extremely uncommon. There have been only a few cases reported in the literature, including lipomas of the falciform ligament of the liver. Here we report a case of torsion and infarction of a lipoma of the ligamentum teres hepatis in a 43-year-old female patient, who presented with acute epigastric pain, nausea and vomiting. Diagnosis was based on computed tomography and magnetic resonance imaging. Patient underwent exploratory laparoscopy followed by laparoscopic excision of the infracted lipoma. Finally, we also provide a mini-review of the literature in order to highlight that although rare, this pathology should be included in the differential diagnosis of acute abdomen.

The Validity of the Distress Thermometer in Greek Colon Cancer Patients.

BACKGROUND: Although screening for distress is a crucial part of psycho-social care for cancer patients, there has not been a validation study for this purpose in Greece. The purpose of this study was to evaluate for the first time the psychometric properties of the Greek translation of the Distress Thermometer (DT) and Problem List (PL) in Greek colorectal cancer patients (CRC). METHODS: Participants were 84 CRC inpatients of the 1st Surgical Propedeutic Department of the Aristotle University of Thessaloniki with a mean age of 70.8±9.5 years. Participants completed the DT, PL and the Hospital Anxiety and -Depression Scale (HADS). RESULTS: The Cronbach's alpha coefficient in the DT was 0.795. Patients' mean score in the DT was 5.7±2.74, while the mean number of the reported problems in the PL was 18.85±5.50 and the mean total score of the HADS was 15.61±6.95. ROC-analysis supported that a cut-off score of 7 gives the optimal sensitivity and specificity for the DT. CONCLUSION: The index sample has manifested high levels of distress, which correspond to high need for support and improvement of the patient-provider relationship. This is probably a difficult task, since the Greek healthcare system has minimal experience of providing psycho-oncology care. The present study has indicated that the DT can be reliably used in the Greek clinical setting. Future studies, along with state provision, are essential in order to offer Greek cancer patients state-of-the-art and comprehensive care.

Surgical management of rectal prolapse.

PURPOSE: Rectal prolapse is uncommon; however, the true incidence is unknown because of underreporting, especially in the elderly population. Full-thickness rectal prolapse, mucosal prolapse and internal prolapse are three different clinical entities, which are often combined and constitute rectal prolapse. The aim of the study is to present our experience in the surgical management of rectal prolapse. METHODS: In a 6-year period (2004-2010), 27 patients were surgically treated for rectal prolapse. The majority of patients were women (25 women, two men) and their mean age was 72.36 years. The operations performed were two Delorme's procedures, five STARR (Stapled TransAnal Rectal Resection), 14 Wells procedures, two Wells combined with Thiersch, one Altemeier, one sigmoid resection combined with Wells and two Thiersch. RESULTS: An emergency sigmoidostomy was performed on a patient after Wells operation due to obstructive ileus. One death occurred on the 5th postoperative day due to pulmonary embolism. Two recurrences observed 8 months postoperatively, one in a patient after STARR operation and one in a patient after Thiersch technique. The great majority of patients are completely relieved of symptoms. CONCLUSIONS: The application of different modalities in the treatment of rectal prolapse is attributed to the fact that cause, degree of prolapse and symptoms, vary from one patient to another. Successful approach depends on many factors, including the status of a patient's anal sphincter muscle before surgery, whether the prolapse is internal or external and the overall condition of the patient.

A retrospective analysis of 2000 cases with colorectal carcinoma.

PURPOSE: Colorectal cancer (CRC) is a major cause of death in the western world and a leading cause of cancer-related death. It is one of the most common human malignancies with >300,000 cases both in the United States and in the European Union each year. The present study was conducted to assess differences in various variables of CRC, such as location of the tumor, differentiation, Dukes classification, 5-year survival and possible changes in these patterns during the examined period. METHODS: We collected data on 2000 patients with colorectal cancer, diagnosed and treated from 1960 to 2008 in 1st Propedeutic Surgical Clinic of Aristotle's University, Thessaloniki. RESULTS: Of 2000 cases reviewed, cancer was almost equal presented to both sexes, for all groups. Rectum was the most common tumor location in all analyzed groups (40.1%). The most common tumor differentiation was the moderate one (68.5%). Concerning tumor staging, Dukes' B tumors were most common (42.5%), and the cancer-related 5-year survival was increased by the time from 42 to 71%. CONCLUSION: In the past 20 years, considerable improvements have been made in colorectal cancer therapy, and patients had received more sophisticated and multidisciplinary treatments, resulting in a better 5-year survival rate.

Rectal endometriosis: a case report.

We present the case of a 45-year-old female patient who was admitted with a history of pelvic pain, constipation, and dysmenorrhea. CT scan and u/s images revealed cholelithiasis, benign nodular hyperplasia of segment IV of the liver and uterine fibromyoma. During laparotomy, firm adhesions between the posterior wall of the uterus and the rectum were found and the incisional biopsy reveals an undifferentiated adenocarcinoma. Then, total resection of the uterus was performed with en block resection of the adherent part of the rectum and part of the posterior wall of the vagina. The final histopathological report showed the presence of uterine fibromyoma, nodular hyperplasia of the liver and rectal endometriosis without any sign of malignancy. The patient after 5 years of follow up remains healthy. Rectal endometriosis represents an uncommon localization of pelvic endometriosis where the symptoms and clinical findings are non-specific making the definitive preoperative diagnosis difficult. Endometriosis should be included in the differential diagnosis of chronic pelvic pain in combination with defecation disorders in female patients of reproductive age.

Gossypiboma presenting as mesosigmoid abscess [corrected].

INTRODUCTION: The term "gossypiboma" is used to describe any mass of non-absorbable surgical material. It is estimated that this complication appears every 1.000-10.000 procedures. It may lead to peritonitis, acute abdominal pain, intraperitoneal abscess, bowel obstruction, or perforation. REPORT OF A CASE: We present the case of an 80-year-old female patient admitted for chronic abdominal pain and fever. A CT scan and MRI were performed with a probable diagnosis of carcinoma or pelvic abscess. A surgical history of hysterectomy and repair of abdominal wall hernia with a mesh were mentioned. RESULTS: Exploratory laparotomy revealed the presence of an irregular, soft mass with characteristics of an abscess located into the mesosigmoid. Hartman's sigmoidectomy was performed, and the patient's postoperative course was uneventful. The histopathological examination confirmed the diagnosis of gossypiboma. CONCLUSIONS: Retained foreign intraperitoneal materials often represent diagnostic dilemmas, since symptomatology is no specific and the time elapsed from surgery is long. The policy of prevention's importance is highly appreciated.

Surgical management of colorectal injuries: colostomy or primary repair?

PURPOSE: Several factors have been considered important for the decision between diversion and primary repair in the surgical management of colorectal injuries. The aim of this study is to clarify whether patients with colorectal injuries need diversion or not. METHODS: From 2008 to 2010, ten patients with colorectal injuries were surgically treated by primary repair or by a staged repair. RESULTS: The patients were five men and five women, with median age 40 years (20-55). Two men and two women had rectal injuries, while 6 patients had colon injuries. The mechanism of trauma in two patients was firearm injuries, in two patients was a stab injury, in four patients was a motor vehicle accident, in one woman was iatrogenic injury during vaginal delivery, and one case was the transanal foreign body insertion. Primary repair was possible in six patients, while diversion was necessary in four patients. CONCLUSIONS: Primary repair should be attempted in the initial surgical management of all penetrating colon and intraperitoneal rectal injuries. Diversion of colonic injuries should only be considered if the colon tissue itself is inappropriate for repair due to severe edema or ischemia. The role of diversion in the management of unrepaired extraperitoneal rectal injuries and in cases with anal sphincter injuries is mandatory.

Changes in treatment of rectal cancer: increased use of low anterior resection.

PURPOSE: The most common surgical procedures for patients with rectal cancer are low anterior resection (LAR) or abdominoperineal excision (APE). The aim of the present study is to evaluate and report the changes in the incidence of LAR and APE in the surgical treatment of rectal cancer over the last 15 years in a single surgical department. METHODS: The patient sample consisted of 251 consecutive patients (mean age 65.17; age range 22-87) that underwent surgical treatment for rectal cancer in a single center from 1996 to 2010. This time frame was divided into three 5-year periods (1996-2000, 2001-2005 and 2006-2010). Patients were classified into one of the aforementioned groups, depending on the date of their treatment. RESULTS: In the first period (1996-2000), 71 patients were treated for rectal cancer. Among them, 32.4% (n = 23) underwent an abdominoperineal excision (APE) while 56.3% (n = 40) were treated with LAR. In the second period (2001-2005), included 102 patients, from which 29.4% (n = 30) received an APE and 60.8% (n = 62) underwent a LAR for their disease. In the final period (2006-2010), from the 78 patients, only 12.8% (n = 10) of them underwent APE, while 74.3% (n = 58) were treated with LAR. There was a statistically significant (chi-square test, P = 0.005) difference between the 3 periods of time concerning the performance of LAR and APE. CONCLUSIONS: According to the results of the present study, the rates of APE seem to decrease during the last 15 years, while LAR is more widely used in the surgical treatment of rectal cancer.

Inflammation of solitary caecal diverticula:a rare aetiology of acute abdominal pain [corrected].

Caecal diverticula are rare, representing the 3.6% of colonic diverticula. They may have congenital origin and remain asymptomatic, presenting as an accidental finding. We present a case of a 42-year-old Caucasian woman, admitted with a 12-h history of sudden onset of sharp right iliac fossa pain, anorexia, and nausea. There was leukocytosis (23.49 × 10(3)/µl) and increased C-reactive protein (11.76 mg/dl). CT scan showed an inflamed appendix. At laparotomy, a diffuse caecal phlegmon with an inflammatory solitary caecal diverticula was found. A limited right hemicolectomy was performed. Histological examination confirmed the caecal diverticulitis without malignancy. Post-operative period was uneventful. Three months later, endoscopy showed no diverticula or other pathologies. Solitary caecal diverticulum is very rare, but surgeons must bear this in mind in case of pain in right iliac fossa.

Ileal pouch dysfunction.

The causes of pouch dysfunction are inflammatory, non-inflammatory and iatrogenic. The most common long-term complication is pouchitis. Diagnosis should be based on clinical symptoms, endoscopic appearance and histologic findings. Ciprofloxacin and metronidazole are the treatment of choice for pouchitis. Fistulae and perianal abscesses should be suspected to be an expression of misdiagnosed Crohn's disease. Strictures are confronted by endoscopic balloon dilatation. Patients who will be refractory to all forms of medical treatment should have surgical treatment such as faecal diversion or pouch revision.

The use of fibrin glue in the treatment of complex perianal fistulae: a case report.

We present a 71-year-old man with a horseshoe, complex perianal fistula. He was treated by a simple fistulotomy for the fistula at sixth hour, while fibrin sealant was applied for the complicated one. He is free of symptoms 24 months postoperatively.

Desmoid tumor of mesentery in familial adenomatous polyposis: a case report.

Our case concerns a 52-year-old male with FAP, who was treated surgically by restorative colectomy and ileal pouch anal anastomosis. Three years later, he presented with acute epigastric pain and obstructive ileum. While a mass in the left lateral abdominal region was palpated. The patient underwent laparotomy, some adhesions were dissected and biopsies were taken from the mass. Pathological examination revealed a desmoid tumor of the mesentery.

Gallstone obstructive ileus 3 years post-cholecystectomy to a patient with an old ileoileal anastomosis.

The present case is one of gallstone obstructive ileus due to gallstones 3 yr after laparoscopic cholecystectomy. It is interesting because of the sex of the patient, the fact that ileus occurred 3 yr after cholecystectomy and that the localization of the obstruction was an old side-to-side ileoileal anastomosis due to a diverticulectomy following intussusception of Meckels' diverticulum at the age of 3.

Groin swelling, the anatomic way out of abdominal haematomas: a case report and explicative literature review.

This case report concerns a previously healthy thirty-five-year-old female with complaints of inguinal hernia that ultimately proved to be a retroperitoneal haematoma. The patient suffered from a car accident 5 months before admission and was hospitalized. During her prior hospitalization, explorative laparotomy revealed a haematoma of the mesentery. The haematoma was treated conservatively, with fluid resuscitation and rest. During her second admission, MRI of the inguinal region revealed localized haematoma. During inguinal exploration, a fluid-filled bluish indirect hernia sac was identified and found to be contoured by free-flowing, non-clotting blood. The postoperative course was uneventful, and the patient was discharged six days following surgery.

Randomized clinical trial of stapled hemorrhoidectomy vs open with Ligasure for prolapsed piles.

BACKGROUND: The aim of the study was to compare the results in 95 patients randomly allocated to undergo either stapled or open hemorrhoidectomy using Ligasure. METHODS: Ninety-five patients with grade III and IV hemorrhoids were randomly allocated to undergo either stapled (50 patients) or open using Ligasure (45 patients). Stapled hemorrhoidectomy was performed with the use of a circular stapling device. Open hemorrhoidectomy was accomplished according to the Milligan-Morgan technique by using Ligasure. Postoperative pain was assessed by means of a visual analog scale (VAS). Recovery evaluation included return to pain-free defecation and normal activities. A 6-month clinical follow-up and an 18 (12-24) month median telephone follow-up were obtained in all patients. RESULTS: Operation time for open hemorrhoidectomy using Ligasure was shorter [median 13 (range 9.2-16.1) min vs 15 (range 8-17) minutes, p < 0.05]. Median range of VAS score in the stapled group were significantly lower [VAS score after 8 h: 3 (2-6) vs 5 (3-8), p < 0.01; VAS score after first defecation: 5 (3-8) vs 7 (3-9), p < 0.001. The stapled hemorrhoidectomy was associated with an increased incidence of intraoperative bleeding in 18 cases (36%) vs four cases (8.8%) of the Ligasure group. There were three cases (6%) from the stapled group with recurrence of the hemorrhoids and none from the open technique. CONCLUSIONS: Hemorrhoidectomy with a circular stapler device is easy to perform, but one more line of clips must be added to the device to avoid intraoperative bleeding from the cut line. Hemorrhoidectomy performed using Ligasure is more painful postoperatively but is a more radical operation.

Effect of ranitidine on healing of normal and transfusion-suppressed experimental anastomoses.

BACKGROUND: Histamine has been shown to participate in immune response. Wound healing is a process of immune system. This experimental study was done to find the effect of histamine2 receptor antagonist ranitidine on the healing process of intestinal anastomosis in rats. METHODS: Eighty Wistar rats in four groups of 20 each underwent colon resection and anastomosis. They were given 2 ml saline or blood, twice daily 0.4 ml saline or 0.4 ml saline containing 0.7 mg ranitidine. The animals were killed 3 or 7 days postoperatively and the anastomotic strength assessed by bursting pressure. RESULTS: The ranitidine group developed fewer anastomotic abscesses (p<0.001). Anastomotic strength was significantly reduced either on day 3 or 7 in animals given blood transfusions (p<0.04, p<0.001), whereas in animals given ranitidine this effect was partially reversed. CONCLUSIONS: These data indicate that ranitidine has no influence in anastomotic bursting pressure, but has a lower incidence of septic complications.

Colorectal cancer in patients over 70 years of age: determinants of outcome.

BACKGROUND: The aim of this study was to evaluate operative risk factors, the mortality, morbidity and survival in old patients with colorectal cancer. METHODS: From 1160 patients with colorectal cancer, 398 patients aged 70 years or older, from 1970 to 2000, were followed-up. Dukes' classification, differentiation, sex, anatomical site and survival were compared with patients <70 years old. RESULTS: Long-term results have been proved to be similar both in young and old patients. Relative survival rate for patients aged 70-95 (70.5%) were similar to those for patients less than 70 years old (71.6%) and also comparable between male (72.3%) and female (68%) patients. CONCLUSIONS: Elderly patients have a lower capacity to react to postoperative complications, but the relative survival is similar to younger patients. Advanced age alone should not be used as a criterion to deny surgery for colorectal cancer.

Prognostic significance of mucinous component in colorectal carcinoma.

BACKGROUND: Many factors influence survival in colorectal cancer patients, one of them is the mucinous component of the tumour. Mucinous adenocarcinoma is characterized by the extracellular mucin of more than 50% of the tumour volume. METHODS: From 1970 to 1999, 1160 patients were admitted to our clinic for colorectal cancer. They were divided into four groups according to mucinous character of the tumour, in two time periods of 15 years. RESULTS: There was an increase in the incidence of mucinous tumours from 20.8 to 30.5% in the second period. These tumours were more advanced (Dukes' C) and especially right sided (34.5% vs. 17.9%). Five-year survival was increased during the second period but was of a lesser degree in the mucinous group (51.5% vs. 65.5%). CONCLUSIONS: Colorectal mucinous carcinomas present at a more advanced stage, predominantly in men, with higher right colon location rate, and a worse overall 5-year survival rate than the non-mucinous colorectal cancers.

Colorectal gastrointestinal mesenchymal tumours. Report of a stromal case of the rectum (GIST) and a leiomyosarcoma of the transverse colon.

BACKGROUND: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal tumours of the gastrointestinal tract. They are positive to C-kit (CD 117), more common in the older males, and mostly in the stomach, less in the colon and rectum and oesophagus. Benign tumours are more common than the malignant ones. Classification of GISTs is based on morphology and immunochemistry. METHODS: We report two cases of colorectal gastrointestinal mesenchymal tumours, one on the transverse colon which was found to be immunohistochemically leiomyosarcoma and the other on the rectum which met the GIST criteria. The patients underwent transversectomy and abdominal perineal resection, respectively. CONCLUSIONS: They did not receive Imanitib postoperatively and two years after there is no evidence of recurrence. Surgery is the treatment of choice for resectable GISTs, and other mesenchymal tumours benign or malignant.
