Prevalence and Natural History of Segmental Colitis Associated With Diverticulosis.

INTRODUCTION: We assessed the prevalence and clinical outcomes of segmental colitis associated with diverticulosis (SCAD) in patients with newly diagnosed diverticulosis. METHODS: A 3-year international, multicenter, prospective cohort study was conducted involving 2,215 patients. RESULTS: SCAD diagnosis was posed in 44 patients (30 male patients; median age: 64.5 years; prevalence of 1.99%, 95% confidence interval, 1.45%-2.66%). Patients with SCAD types D and B showed worse symptoms, higher fecal calprotectin values, needed more steroids, and reached less likely complete remission. DISCUSSION: Although SCAD generally had a benign outcome, types B and D were associated with more severe symptoms and worse clinical course.

Subhepatic mass occurrence after using oxidized and regenerated cellulose polymer in laparoscopic cholecystectomy: a case series.

BACKGROUND: Oxidized regenerated cellulose (ORC) is a bioabsorbable surgical hemostatic. We present the first prospective case series of circumscribed mass occurrence after using ORC in laparoscopic cholecystectomy. METHODS: Tabotamp (Ethicon, Inc., Somerville, NJ) in the form of tightly woven knitted patches was used to achieve hemostasis in 83 patients submitted to LC. RESULTS: A subhepatic mass was detected in five patients and radiologic characteristics were described. Abdominal contrast enhanced CT showed a heterogeneous soft-tissue mass. NMR was performed in one patient and showed a T2-weighted hyperintense mass. CONCLUSION: ORC retention after surgery is not uncommon at long-term follow-up. The radiologic characteristics of a suspected ORC retention mass can differentiate it from a neoplastic lesion, so that surgery can be avoided.

Complete mesh migration into the small bowel after incisional hernia repair: a case report and literature review.

INTRODUCTION: Mesh migration into the intestine is very rare after incisional hernia repair. CASE REPORT: We report the case of transmural mesh migration from the abdominal wall into the small bowel presenting as recurrent small bowel obstruction 18 years after repeated surgical repair of an incisional ventral hernia. At surgery, a mesh was found inside the resected ileal loop. DISCUSSION: Mesh migration into the intestine is a possible, although very rare, complication after incisional hernia repair with nonabsorbable meshes. It tends to occur late with obstructive symptoms, especially if the small intestine is involved. Avoiding the direct contact between the mesh and the intestinal wall may help to reduce this complication.

A rare case of primary gastric Burkitt's lymphoma associated with malignant pleural mesothelioma.

BACKGROUND: Primary gastric Burkitt lymphoma (PG BL) and malignant pleural mesothelioma (MPM) are rare and aggressive tumors with poor prognosis. HIV and EBV infection have a link in the aetiology of PG BL, while MPM is usually associated with asbestos exposure. Endoluminal bleeding from massive solid tumor, and dyspnea usually due to pleural effusion, are the typical clinical manifestations respectively of PG BL and MPM. In most patients just palliative treatment is indicated. CASE REPORT: A caucasian elderly male, negative for the proven risk factors, presenting respiratory failure due to massive left pleural effusion with severe mediastinal shift. Contrast enhanced - Computed Tomography (CE-CT) showed a large mass causing circumferential thickening of the gastric fundus, infiltrating the left diaphragmatic dome and the ipsilateral crus. Macroscopically, on endoscopy the gastric fundus appeared completely occupied by an ulcerated large mass protunding in the gastric lumen. Histopathological examination from biopsy specimens taken during esophagogastroduodenoscopy and thoracoscopy allowed to make diagnosis of PG BL and MPM. The patient first underwent a placement of a chest tube drainage for the pleural effusion and then a thoracoscopic talc insufflation (TTI) in the left hemithorax. A surgical treatment of the gastric lesion was planned, due to the rapid growth and the high risk of bleeding. The patient died because of fatal cardiac arrhythmia, before undergoig abdominal surgery. CONCLUSIONS: This report presents an unique case of PG BL associated with MPM and highlights the real challenge for the physicians to identify them in early stage, especially in patients without the proved risk factors. The onset symptoms make it a very singular case, characterized by severe dyspnea up to respiratory failure, due to massive left pleural effusion and contralateral mediastinal fluttering, without an active bleeding from the gastric mass, while CE-CT findings were instead negative for pleural thickening and positive for circumferential thickening of the gastric fundus. KEY WORDS: Burkitt Lymphoma, Case Report, Gastric, Pleural Mesothelioma, Pleural Effusion, Respiratory Failure.

Management of incidental pancreatic neuroendocrine tumor: a case report with literature review.

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are rare and accounting for less than 5% of all pancreatic neoplasms. Their management depends on dimension of the lesion, main pancreatic duct (MPD) caliber, tumor malignancy features and evolutive potential. CASE REPORT: Incidental finding of a lesion 1.2 cm wide of the pancreatic body, after contrast enhanced total body CT, in a 71 years old obese Caucasian male (BMI>25), during follow-up for cutaneous melanoma. The lesion was confirmed by MRI and 68-Ga pancreatic scintigraphy. EUS showed a second hypoecogenic and hypovascularized lesion compatible with pancreatic tail PNET. After FNB, Ki-67 was below 3%. DISCUSSION: 68-Gallium PET-CT was the preferred technique for the staging of the neuroendocrine neoplasm, for treatment planning, for the localization of the pancreatic lesion, excluding the presence of unknown extra-pancreatic lesions. EUS-FNB is indicated in patient with suspicion of PNET, although further investigation is needed to include it as a routine diagnostic examination. CONCLUSION: Surgery is mandatory in case of PNETs larger than 2 cm, with MPD dilation, Ki-67>20% and compression symptoms.

Incidental papillary thyroid microcarcinoma in consecutive patients undergoing thyroid surgery for benign disease. A single center experience.

BACKGROUND: There has recently been an increase in the incidental histological diagnosis of papillary thyroid microcarcinoma (I-PTMC), that varies from 3.5% in autopsies studies, to 5.2% in thyroid specimens from thyroid surgery, up to 9.4% in patients from areas of endemic goiter. AIM: To evaluate the incidence and the histological characteristics of I-PTMC in patients undergoing thyroidectomy for benign thyroid diseases, and to evaluate sex, age, toxic and non-toxic goiter, Hashimoto's thyroiditis as potential risk factors. MATERIALS AND METHODS: Prospective observational study on 124 patients, median age 56.3±13.25sd range 24-80 years, 93(75%)F, 31(25%)M, with surgical indications for toxic and non-toxic uni/multinodular goiters, in pharmacological euthyroidism. An accurate histological examination (HE) of entirely embedding thyroid samples was performed to identify microscopic foci of I-PTCM. Logistic regression analysis of the abovementioned parameters was performed to identify the risk factors. RESULTS: Total incidence of I-PTMC was 15.3%(19/124), with F/M ratio 2:1. All I-PTMCs were intraparenchymal with an intact thyroid capsule; 68.5% were bilateral-multifocal, 21% unilateral-unifocal, 10.5% unilateral-multifocal; maximum diameter was <5mm in 57.9% and ≥5mm in 42.1%; 63.1% were follicular variant, 36.9% classical variant; intra-thyroid lymphatic invasion and lymph node infiltration of the central compartment and para-tracheal was found in the only patient with "tall-cell" classical variant. No risk factors was found. CONCLUSIONS: The incidence higher than that reported in the literature, is probably due to the accurate HE of entirely embedding thyroid samples, which is the most important tool to identify microscopic foci of I-PTCM. The highest reported rate of bilateral multifocality of the neoplasm recommend the total thyroidectomy as surgical treatment of choice, also in patients undergoing thyroid surgery for "presumptive" benign diseases. KEY WORDS: Benign Thyroid Disease, Incidental Papillary Thyroid Microcarcinoma, I-PTCM, Thyroid Surgery.

Diverticular Inflammation and Complication Assessment classification, CODA score and fecal calprotectin in clinical assessment of patients with diverticular disease: A decision curve analysis.

BACKGROUND AND AIMS: The Diverticular Inflammation and Complication Assessment (DICA) classification and the Combined Overview on Diverticular Assessment (CODA) were found to be effective in predicting the outcomes of Diverticular Disease (DD). We ascertain whether fecal calprotectin (FC) can further aid in improving risk stratification. METHODS: A three-year international, multicentre, prospective cohort study was conducted involving 43 Gastroenterology and Endoscopy centres. Survival methods for censored observations were used to estimate the risk of acute diverticulitis (AD) in newly diagnosed DD patients according to basal FC, DICA, and CODA. The net benefit of management strategies based on DICA, CODA and FC in addition to CODA was assessed with decision curve analysis, which incorporates the harms and benefits of using a prognostic model for clinical decisions. RESULTS: At the first diagnosis of diverticulosis/DD, 871 participants underwent FC measurement. FC was associated with the risk of AD at 3 years (HR per each base 10 logarithm increase: 3.29; 95% confidence interval, 2.13-5.10) and showed moderate discrimination (c-statistic: 0.685; 0.614-0.756). DICA and CODA were more accurate predictors of AD than FC. However, FC showed high discrimination capacity to predict AD at 3 months, which was not maintained at longer follow-up times. The decision curve analysis comparing the combination of FC and CODA with CODA alone did not clearly indicate a larger net benefit of one strategy over the other. CONCLUSIONS: FC measurement could be used as a complementary tool to assess the immediate risk of AD. In all other cases, treatment strategies based on the CODA score alone should be recommended.

Drain after elective laparoscopic cholecystectomy. A randomized multicentre controlled trial.

BACKGROUND: Routine drainage after laparoscopic cholecystectomy is still debatable. The present study was designed to assess the role of drains in laparoscopic cholecystectomy performed for nonacutely inflamed gallbladder. METHODS: After laparoscopic gallbladder removal, 53 patients were randomized to have a suction drain positioned in the subhepatic space and 53 patients to have a sham drain. The primary outcome measure was the presence of subhepatic fluid collection at abdominal ultrasonography, performed 24 h after surgery. Secondary outcome measures were postoperative abdominal and shoulder tip pain, use of analgesics, nausea, vomiting, and morbidity. RESULTS: Subhepatic fluid collection was not found in 45 patients (84.9 %) in group A and in 46 patients (86.8 %) in group B (difference 1.9 (95 % confidence interval -11.37 to 15.17; P = 0.998). No significant difference in visual analogue scale scores with respect to abdominal and shoulder pain, use of parenteral ketorolac, nausea, and vomiting were found in either group. Two (1.9 %) significant hemorrhagic events occurred postoperatively. Wound infection was observed in three patients (5.7 %) in group A and two patients (3.8 %) in group B (difference 1.9 (95 % CI -6.19 to 9.99; P = 0.997). CONCLUSIONS: The present study was unable to prove that the drain was useful in elective, uncomplicated LC.

Evaluation of the oncogenic risk of diffuse gastric polyposis. A case report.

Benign polyps of the stomach undergo malignant transformation at a rate correlating to the histological type and size of the proliferative lesion. We report a case of a 50-year-old Caucasian woman, affected by a diffuse gastric polyposis of both hyperplastic and adenomatous type. At endoscopy polyps were more than 1,000, scattered over the entire gastric cavity. The patient underwent total gastrectomy. The perilesional gastric mucosa was characterized by the presence of either atrophic or metaplastic areas and by a mild dysplasia. A single tubulo-villous adenomatous polyp was also present in the ascending tract of the colon. The absence of both high-grade dysplastic lesions and outbreaks of neoplastic transformation well correlated with the histochemical and molecular features, confirming the highly proliferative pattern of the polyps in the lack of signs of malignant progression.

About a case of squamous cell carcinoma of the scalp. Management and aesthetic results.

We present a case of squamous cell carcinoma of the scalp, treated with local excision and flap reconstruction. We discuss the treatment modalities of this pathology with particular attention to the role of surgery and adjuvant radiotherapy. The authors suggest the systematic use of subgaleal drainage to avoid the hematoma and/or seroma occurrence.

Post-traumatic multifocal abdominal splenosis. The role of the clinical history. Case report and review of literature.

BACKGROUND: Splenosis is a benign clinical condition caused by the heterotopic autotransplantation of spleen's tissue tipically occurring after spleen rupture. Splenosis may be asymptomatic and found accidentally. When signs and symptoms occur they are due to mass effect or bleeding of the splenic nodules. CASE REPORT: 74-years-old male presenting with intestinal sub-occlusion and past medical history of post-traumatic splenectomy at 18-years-old. Based on TC findings of multiple hyperenhanced solid lesions located in greater omentum, mesentery and parietal peritoneum of right pelvic walls, the presumptive diagnosis was peritoneal carcinomatosis of unknown primary site. Stenosis of a ileum loop in the right pelvis, with dilatation and faecal stasis of the upstream loops proximal, required surgical procedure. At the opening of the peritoneal cavity the multifocal lesions varied in size, were reddish blu color, sessile, lobulate and with strong adhesions to the visceral peritoneum. Omentectomy and the blunt exicision of 3 extraparietal solid nodules, which had tenacious adhesions with stenotic ileum loop serosa for the lenght of 8 cm, were performed. Histopathological examination of surgical specimens showed splenic tissue with red pulp. CONCLUSION: CT scan usually do not allow to make a certain diagnosis of splenosis, so the clinical history of splenic trauma or splenectomy, positive in all cases reported in literature, represent the key in the diagnostic pathway of splenosis. Management should be conservative as much as possible nonetheless in abdominal splenosis the surgical approach should be chosen for the symptomatic patients who present abdominal pain, occlusion or bleeding. KEY WORDS: Abdominal, Splenosis, Spleen, Surgery.

Sporadic diffuse gastric polyposis: Report of a case.

A 50-year-old woman was admitted because of severe sideropenic anemia. The gastrin levels were within normal ranges. Esophagogastroduodenoscopy showed diffuse gastric polyposis with signs of diffuse oozing. Colonoscopy showed the presence of a 3-cm wide pedunculated polyp of the ascending colon, which was removed by diathermy. The patient was treated by total gastrectomy with Roux-Y esophagojejunostomy. Histological examination showed the presence of diffuse gastric polyposis with the contemporary occurrence of hyperplastic polyps and mixed hyperplastic and adenomatous polyps, with a tubular pattern and the focal aspect of serrate adenoma. This is the first case report of sporadic diffuse hyperplastic and adenomatous polyposis of the stomach.

Acute pancreatitis secondary to non-functioning pancreatic neuroendocrine tumor: uncommon clinical presentation. Clinical case and review of literature.

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are uncommon, representing <5% of all pancreatic neoplasms, divided into functioning PNETs with secreted hormone cause of specific symptoms, and non-functioning PNETs (nf- PNETs) characterized by delayed diagnosis with metastases and clinical manifestations of compressive effects. Surgical approach is recommended for functioning and nf-PNETs >2 cm in diameter. CASE REPORT: A 76-year-old woman was admitted to the UOC-University-Surgery Hospital "A. Fiorini" in Terracina for nausea and pain in the upper abdominal quadrants with dorso-lumbar irradiation, arising after the evening meal. After the haematochemistry tests and the instrumental investigations, the diagnosis of acute, severe halitiasic pancreatitis was made. Conventional US, CCT, CE-MRI and EUS showed a 2.8cm diameter lesion in the head-body junction of the pancreas. FNA-cytological examination did not found the presence of atypical pancreatic cells. Total-body scintigraphy with Octreoscan® documented a pathological hypercaptation area located in correspondence with the neoformation. The patient underwent a body-tail spleno-pancreatectomy. The histological examination showed an intermediate grade (G2) nf-PNET infiltrating the lienal vein and stenosing the Wirsung duct, with perilesional pancreatitis. Immunohistochemistry showed CAM 5.2, Synaptophysin (>95%) and Chromogranin (60%) positive immunophenotype, with negative intratumoral Somatostatin expression. CONCLUSION: Although rarely, nf-PNETS may be the cause of severe non-biliary acute pancreatitis from pancreatic ductal system compression. In cases where PET/CT68Ga cannot be performed, total-body scintigraphy with Octreoscan® remains the most widely used method for the diagnosis of PNETs and the identification of extra-pancreatic lesions. Chromogranin and Synaptophysin are confirmed as specific markers of neuroendocrine differentiation. KEY WORDS: Acute pancreatitis, Chromogranin, Pancreatic neuroendocrine tumor, Synaptophysin, Somatostatin.

An uncommon clinical presentation of primary pancreatic lymphoma: Bleeding. Case report and literature review.

BACKGROUND: Primary pancreatic lymphoma (PPL) represents less than 0.5% of all pancreatic neoplasms. Clinical manifestations are non-specific and diagnosis is delayed in the majority of patients. CASE REPORT: 85-year-old woman reporting accidental fall at home 20-days earlier, was admitted with diagnosed of acute abdomen from suspected two-stage rupture of the spleen. The patient complained of pain in the upper abdomen. Blood-chemical tests did not show anemia and leukocytosis, but showed increased CA19.9, CA125, LDH and beta2- microglobulin. Contrast-enhanced CT showed left pleural, perisplenic, perihepatic, and Douglas blood effusion, a neoformation of the body-tail of the pancreas with peri-pancreatic blood layer, splenomegaly due to the presence of a hypodense area as from intraparenchymal hematoma, with an apparently undamaged splenic capsule. The patient underwent emergency exploratory laparotomy, that revealed the presence of modest free serohematic effusion from oozing of the pancreatic neoformation. The local spread of the disease prevented any attempt at surgical resection. Bleeding was checked with the addition of topical hemostats (Tabotamp®) and biopsy sampling of the pancreatic mass was performed. A final histological diagnosis of large cell NHL of centro-follicular origin, double expressor for the CMYC and BCL2 protein, was achieved. The age of the patient, the poor general conditions, the associated pathologies, the locally advanced spread of the disease and the histological aggressiveness, were contraindications to chemo-radiotherapy treatments. CONCLUSION: The initial misdiagnosis was due to the history of recent trauma, the uncommon clinical presentation, the underestimation of the serum increase in markers and the interpretation of the CT. KEY WORDS: Acute Abdomen, Hemoperitoneum, Primary Pancreatic Lymphoma.

Laparoscopic correction of enterocele associated to stapled transanal rectal resection for obstructed defecation syndrome.

BACKGROUND AND AIMS: We report our experience of concomitant laparoscopic treatment for enterocele and stapled transanal rectal resection (STARR) for rectocele and/or rectal prolapse in patients with complex obstructed defecation syndrome (ODS). PATIENTS AND METHODS: From June 2005 to June 2007, we submitted 20 patients with ODS due to rectal prolapse and/or rectocele, combined with stable enterocele, to STARR and laparoscopic correction of the enterocele. Preoperative assessment included symptom evaluation with standardized questionnaires, clinical examination, colonoscopy, proctoscopy, anal sphincter ultrasonography, video-defecography with synchronous opacification of the ileal loops in all patients and colpography in female patients, and anorectal manometry. Follow-up was performed in the first, third, sixth, 12th, and 24th month after surgery. RESULTS: Eighteen (90%) patients were submitted to both procedures, simultaneously. One patient, previously submitted to STARR, underwent laparoscopic treatment of the enterocele. Postoperative complications occurred in two (10%) patients: one case of postoperative rectal bleeding and one case of retropneumoperitoneum. Median (range) preoperative and postoperative Altomare's obstructed defecation score was ten (6-14) and two (0-14), respectively (p<0.001). Median (range) preoperative and postoperative quality of life score was 79 (39-109) and 109 (50-126), respectively (p<0.001). No symptom related to ODS was detected at 6-month follow-up (19 patients) and at 24-month follow-up (19 patients). CONCLUSION: The combination of STARR and laparoscopy provides a safe and effective method to treat ODS caused by rectal internal prolapse and/or rectocele combined with enterocele.

Gallstone ileus. Report of two cases.

Gallstone ileus is uncommon. Gallstone impaction in the jejunum was rarely reported. We report two cases of gallstone impaction in the proximal jejunum and in the distal ileum. One patient was treated with enterolithotomy alone and in the other one enterolithotomy was combined to cholecystectomy and repair of a cholecystoduodenal fistula. Contrast-enhanced computed tomography of the abdomen is the mainstay of diagnosis. One-stage procedure including both enterolithotomy and cholecystectomy with bilioenteric fistula repair should be reserved to low-risk patients.

Non-antibiotic prophylaxis in thyroid surgery. Experience of a single Institution and revision of literature.

AIM: To evaluate the incidence of SSI and systemic infectious complications in a consecutive series of patients undergoing thyroid surgery in the absence of prophylactic antibiotic (NO-AP). METHODS: Prospective observational study including 77 patients who underwent total thyroidectomy and completion of previous hemithyroidectomy in NO-AP. The surgical intervention was performed by surgeons who were experienced in the procedure, and involved the use of Ligasure Harmonic Ethicon®, absorbable hemostat in oxidized regenerated cellulose (Tabotamp®), and skin incision suture device Skin Stapler®. The following risk factors were assessed: gender, age, BMI, alcohol consumption, habitual smoking, co-morbidities, ASA score, indication to surgery, duration of anesthesia and procedure lenght, type of surgical procedure, fever, white blood cells count, dosage of the pre-operative C Reactive Protein in the five first post-operative day, and histological diagnosis. The data were collected and processed using IBM SPSS software v.23.0. RESULTS: No factors of increased infectious risk have been identified. No infectious surgical and systemic complications have been reported causes of prolongation of the length of the hospital stay. CONCLUSIONS: Fever, neutrophilic leukocytosis and increased PCR cannot be assessed as predictive factors of infectious complication in thyroid surgery. The cutaneous antisepsis of the operative field with chlorhexidine gluconate, the improvement of the surgical technique, the protection of the cutaneous margins of incision, the use of new devices, the accurate hemostasis and the reduction of surgery time lead to a lack of SSIs and systemic infection complications in all patients undergoing thyroid surgery in NO-AP. KEY WORDS: Antibiotic prophylaxis, Surgical site infections, Thyroid surgery, Thyroidectomy.

Prophylactic drainage after laparoscopic cholecystectomy for acute cholecystitis: a systematic review and meta-analysis.

In the literature, there is a large evidence against the use of drains in laparoscopic cholecystectomy (LC) in elective surgery. However, evidence is lacking in the setting of acute cholecystitis (AC). The present meta-analysis was performed to assess the role of drains to reduce complications and improve recovery in LC for AC. An electronic search of the MEDLINE, Science Citation Index Expanded, SpringerLink, Scopus, and Cochrane Library database from January 1990 to July 2018 was performed to identify randomized clinical trials (RCTs) that compare prophylactic drainage with no drainage in LC for AC. Odds ratio (OR) with confidence interval (CI) for qualitative variables and mean difference (MD) with CI for continuous variables were calculated. Three RCTs were included in the meta-analysis, involving 382 patients randomized to drain (188) versus no drain (194). Morbidity was similar in both the study groups (OR 1.23; 95% CI 0.55-2.76; p = 0.61) as well as wound infection rate (OR 1.98; 95% CI 0.53-7.40; p = 0.31) and abdominal abscess rate (OR 0.62; 95% CI 0.08-4.71; p = 0.31). Abdominal pain 24 h after surgery was less severe in the no drain group (MD 0.80; 95% CI 0.46-1.14; p < 0.000). A significant difference in favor of the no drain group was found in the postoperative hospital stay (MD 1.05; 95% CI 0.87-1.22; p < 0.000). No significant difference was present with respect to postoperative fluid collection in the subhepatic area and operative time. The present study shows that prophylactic drain placement is useless to reduce complications in LC performed to treat AC. Postoperative recovery is improved if drain is not present.

Polypoid lesions of the gallbladder in a consecutive series of 2631 patients. A single-center experience.

BACKGROUND: Challenges in the diagnosis of polypoid gallbladder lesion (PLG) is due to the low sensibility (SE) of ultrasound scan (US), and the selection criteria of patients with PLG to be addressed to surgical treatment or followup are not yet fully defined. MATERIALS AND METHODS: Retrospective observational study was conducted on 2631 patients, 1175(44.6%) M, mean age 56 years, 1456(55.4%) F, mean age 46 years, who underwent laparoscopic and open cholecystectomy. RESULTS: The US diagnosis for PLG was placed in 38/2631(1.4%) patients. On histological examination (HE) the polyps were identified in 68/2631(2.6%) patients and it was associated with biliary lithiasis in 28/2631 (1.1%) cases. From the US and HE comparison, the ultrasound diagnosis was burdened by false positives (8/38; 21%) and false negatives (38/2631;1.45%), with SE 44% (95% c.i.:32.2-55.7). The histological incidence of gall bladder cancer (GBC) was 0.38%(10/2631). DISCUSSION: US survey underestimated the incidence of PLG compared to the histological finding (p=0.021). Female gender has been shown to be a specific risk factor for benign and malignant PLG and non-polypoid mucosal lesions (p=0.041). The parietal lesion size <0.5cm does not exclude the neoplastic nature. Currently the prevention and diagnosis of GBC is based on the early detection and treatment of potentially evolutionary polypoid lesions over a period of about 15 years. CONCLUSIONS: It is probably that early cholecystectomy in all the patients with PLG of diameter <1cm, isolated or associated with lithiasis, symptomatic and asymptomatic, can contribute to the reduction of the incidence of GBC. KEY WORDS: Cholecystectomy, Gallbladder polyps, Gallbladder cancer, Ultrasound scan.

Long-term outcome of stapled hemorrhoidopexy for Grade III and Grade IV hemorrhoids.

PURPOSE: This study was designed to assess the long-term results of stapled hemorrhoidopexy in 291 patients with Grade III and Grade IV hemorrhoids after a minimum follow-up of five years. METHODS: Records of patients submitted to stapled hemorrhoidopexy for Grade III and Grade IV hemorrhoids between January 1999 and December 2002 were retrospectively analyzed. Long-term outcome was evaluated with a standardized questionnaire and an office visit, including anorectal examination and rigid proctoscopy. RESULTS: A total of 291 patients with Grade III (57.4 percent) and Grade IV (42.6 percent) hemorrhoids were evaluated. Intraoperative (20.3 percent) and postoperative (4.8 percent) bleeding was the most frequent complication. The questionnaire was submitted to all patients at a median follow-up of 73 (range 60-93) months. There were no symptoms related to hemorrhoids in 65.3 percent of patients, moderate symptoms in 25.4 percent of patients, and severe symptoms in 9.3 percent of patients. Fifty-three (18.2 percent) patients had recurrence. Reoperation was necessary in 21 (7.2 percent) patients (4 in Grade III hemorrhoids and 17 in Grade IV hemorrhoids; P < 0.001), with no recurrent symptoms and/or prolapse. Patient satisfaction for operation was 89.7 percent. CONCLUSIONS: Stapled hemorrhoidopexy is a safe and effective treatment for Grade III and Grade IV hemorrhoids. Recurrence requiring reoperation was higher in Grade IV hemorrhoids than in Grade III hemorrhoids.
