Extrauterine leiomyomata presenting with sepsis requiring hemicolectomy

Extrauterine leiomyomas are rare, benign, and may arise in any anatomic sites. Their unusual growth pattern may even mimic malignancy and can result in a clinical dilemma. Occasionally, uterine leiomyomas become adherent to surrounding structures. They also develop an auxiliary blood supply, and lose their original attachment to the uterus, thus becoming 'parasitic'. Parasitic myomas may also be iatrogenically created after uterine fibroid surgery, particularly if morcellation is used. This report presented two cases of parasitic myomas with sepsis, both requiring right hemicolectomy. It reviewed the pertinent literature.

Linfoma ileal primário como uma causa de intussuscepção ileocecal recorrente

INTRODUÇÃO: A intussuscepção ocorre quando um segmento proximal do intestino invagina para dentro do lúmen do segmento distal adjacente. Esta patologia é relativamente comum em crianças, sendo geralmente idiopática, diferentemente do que é evidenciado em adolescentes e adultos, os quais apresentam uma causa orgânica comprovada na maioria dos casos. O linfoma intestinal como etiologia desta patologia é extremamente raro. RELATO DE CASO: Um paciente de 16 anos, masculino, referindo dor abdominal em quadrante inferior direito há 36 horas associada a vômitos e fezes com sangue vivo compareceu em nosso serviço. O exame físico se apresentava dentro da normalidade exceto por uma massa palpável no quadrante inferior direito. A ultra-sonografia abdominal revelou intussuscepção ileocecal. A colonoscopia demonstrou uma massa protuberante proveniente do orifício da válvula ileocecal que foi reduzida, tendo o paciente um alívio completo dos sintomas. Três semanas após, o paciente retornou ao nosso hospital com recorrência dos sintomas. Uma laparotomia exploradora foi realizada evidenciando uma massa polipóide no íleo terminal com intussuscepção para dentro do ceco. Uma colectomia direita ampliada foi realizada. Após exame patológico da peça e estadiamento tumoral, um linfoma de Burkitt primário foi diagnosticado. A recuperação pós-operatória não apresentou intercorrências e o paciente foi encaminhado para quimioterapia adjuvante.

National audit of anaesthesia for major abdominal surgery

A postal survey was conducted of all hospitals in Australia known to have a department of anaesthesia and an intensive care or high dependency unit. Each hospital was asked to report the anaesthetic and postoperative analgesic techniques used for the last ten cases of four common major surgical procedures-aorto-femoral bypass, repair of an abdominal aortic aneurysm, hemicolectomy and anterior resection of the rectum. Half of 76 hospitals sent a survey form completed and returned it. Responding hospitals were larger on average, than non-responding ones, but otherwise typical of them in terms of university affiliation and metropolitan versus rural location. For each of the procedures studied the proportion of cases in which epidural block was used intra- or postoperatively varied from 0% to 100%. Depending on the procedure, between 65% and 85% of hospitals used epidural block sometimes, with between 10% and 90% of patients in these hospitals being managed with this technique. There is wide variation in the use of epidural block, intra- and postoperatively, in Australia, variation that is unlikely to be explained by systematic differences between institutions in the patients seen or their suitability for one or other technique. This pattern of practice mirrors the lack of agreement about the proper place for epidural techniques evident in the recent literature. There is a widespread belief among clinicians that this is a question of great importance. Accordingly, we believe that anaesthetists and surgeons share an ethical responsibility to enter suitable patients in an appropriately designed randomized controlled trial in order to resolve this question.

Adenocarcinoma of the Ileum: A Rare and Challenging Entity

INTRODUCTION: Primary small bowel malignancy is unusual and accounts for 1-3% of all gastrointestinal tract neoplasms. Adenocarcinoma is one of the most common histologic types, but its frequency decreases with more distal locations. Its clinical presentation is nonspecific and is usually associated with advanced disease, which contributes to delayed diagnosis. PRESENTATION OF CASE: A 66-year-old woman was admitted to the hospital with a 6-day history of progressively worsening abdominal pain localized in the right lower quadrant, nausea, and vomiting. Investigation revealed an inflammatory appendiceal tumor. The patient underwent surgery and an unexpected tumor involving the distal ileal segment and ileocecal appendix was found. Right radical hemicolectomy with en bloc resection of the distal ileum was performed. Histopathological examination revealed adenocarcinoma of the ileum. DISCUSSION: This rare entity is associated with a nonspecific clinical presentation that contributes to delayed diagnosis and treatment, and consequently to a worse prognosis. Approximately half of the cases are only diagnosed at surgery. Primary treatment consists of wide resection with locoregional lymphadenectomy. The role of adjuvant chemotherapy has yet to be determined. CONCLUSION: This case demonstrates an unusual condition characterized by late and challenging diagnosis. We highlight the importance of an earlier diagnosis and optimal treatment for improved patient outcomes.

Néoplasie épithéliale de l'appendice: quoi de neuf [Epithelial neoplasia of the appendix: what has recently changed?].

Appendicular tumors are mostly found incidentally in up to 1.5% of all appendectomies. Neuroendocrine tumors are the commonest malignancies, and are associated with an excellent long-term prognosis. While small lesions located at the appendicular tip can be treated with simple appendectomy, advanced tumors require right hemicolectomy. Goblet cell carcinoids are rare tumors showing a mixed phenotype. Long-term outcome is impaired, and for most cases a right hemicolectomy is mandatory. Colonic-type adenocarcinomas have a similar behavior like conventional colonic cancer and should be treated similarly. Mucinous neoplasias possess the characteristic of extensive mucin production with intraperitoneal spread. Treatment options are ranging from right hemicolectomy to multivisceral resection with intraperitoneal chemotherapy.

Transvaginal specimen extraction in colorectal surgery: current state of the art.

Aim  Background The expected benefit of transvaginal specimen extraction is reduced incision-related morbidity. Objectives A systematic review of transvaginal specimen extraction in colorectal surgery was carried out to assess this expectation. Method  Search strategy The following keywords, in various combinations, were searched: NOSE (natural orifices specimen extraction), colorectal, colon surgery, transvaginal, right hemicolectomy, left hemicolectomy, low anterior resection, sigmoidectomy, ileocaecal resection, proctocolectomy, colon cancer, sigmoid diverticulitis and inflammatory bowel diseases. Selection criteria Selection criteria included large bowel resection with transvaginal specimen extraction, laparoscopic approach, human studies and English language. Exclusion criteria were experimental studies and laparotomic approach or local excision. All articles published up to February 2011 were included. Results  Twenty-three articles (including a total of 130 patients) fulfilled the search criteria. The primary diagnosis was colorectal cancer in 51% (67) of patients, endometriosis in 46% (60) of patients and other conditions in the remaining patients. A concurrent gynaecological procedure was performed in 17% (22) of patients. One case of conversion to laparotomy was reported. In two patients, transvaginal extraction failed. In left- and right-sided resections, the rate of severe complications was 3.7% and 2%, respectively. Two significant complications, one of pelvic seroma and one of rectovaginal fistula, were likely to have been related to transvaginal extraction. The degree of follow up was specified in only one study. Harvested nodes and negative margins were adequate and reported in 70% of oncological cases. Conclusion  Vaginal extraction of a colorectal surgery specimen shows potential benefit, particularly when associated with a gynaecological procedure. Data from prospective randomized trials are needed to support the routine use of this technique.

Tumor do apêndice vermiforme

Appendiceal tumors are rare and usually presented as acute appendicitis. They are incidentally discovered at an emergency surgery, in which case the decision-making is very difficult. The purpose of this report is discuss to the most appropriate management for appendiceal tumors. A retrospective analysis of one case treated at HU-UEL was undertaken and the literature was reviewed. The conclusion is that frozen section should be done whenever the appendiceal findings are atypical. For appendiceal carcinoids greater than 2 cm and adenocarcinomas, a right hemicolectomy is recommended. Appendectomy is apropriate for patients whose carcinoid tumors are 1 cm in diameter or less and for carcinoid tumors between 1 cm and 2 cm without extensive lymphatic permeation and mesenteric invasion. Every case should be searched for synchronous tumors.

Adenocarcinoma de apêndice: relato de dois casos

The authors report two cases of patients with appendix adenocarcinoma, manifested as a syndrome of abdominal tumor of unknown origin. It was not possible to perform etiological diagnosis in the preoperative period for any of them. Literature data show that large locoregional tumor is a manifestation of appendix adenocarcinoma, although acute appendicites is the most frequent clinical manifestation. Preoperative diagnosis is rare and usually performed during laparotomy or through histopathological examination of the specimen. In large tumors, total mass resection including hemicolectomy should be carried out whenever possible. Whenever diagnosis of appendix adenocarcinoma is performed by the histopathological examination of the acute appendicites specimen, re-intervention is indicated for a right hemicolectomy.

Duodenopancreatectomia e hemicolectomia direita em monobloco para tratamento de câncer de cólon direito localmente avançado

This article reports the case of a patient whit a diagnosis of diarrhea and weight loss. Subsidiary exams showed ulcerovegetant lesion in the second duodenal portion and duodenocolic fistula. An exploratory laparotomy was performed and a neoplasic lesion in the hepatic angle of the colon was observed invading the second duodenal portion. The patient then underwent a cephalic gastroduodenopancreatectomy associated with en bloc right hemicolectomy and improved well in the postoperative period. Currently, 48 months after the surgery, he does not present any signs of the disease dissemination or recurrence. The consulted literature recommends that multivisceral resection must be considered if the patient is clinically able to undergo major surgery and does not present any signs of neoplasic dissemination, since the postoperative survival time is considerably longer in the resected group and some of these patients even achieve cure.

Infecciones en pacientes tratados con citorreducción peritoneal mas quimioterapia hipertérmica intraperitoneal

Introducción:Los individuos en quienes se realiza el sugarbaker tienen diagnósticos tumorales bien caracterizados. Actualmente no se dispone en la literatura médica universal de comparadores previos que permitan estimar la morbilidad relacionada específicamente con procesos infecciosos en pacientes sometidos al procedimiento, por tanto se presenta la caracterización de procesos febriles e infecciosos en el postoperatorio de la cohorte de pacientes intervenidos en la FSFB y de los factores de riesgo asociados a su manifestación. Métodos:Estudio descriptivo con componente analítico de una cohorte ambidireccional compuesta por pacientes intervenidos en la FSFB mediante el procedimiento de Sugarbaker. Resultados:En total se incluyeron en el estudio 53 pacientes consecutivos (37mujeres y 16hombres), quienes fueron llevados al procedimiento de peritonectomía radical más quimioterapia hipertérmica intraperitoneal entre el mes de nov/2007 y jun/2012 en el Hospital-Universitario Fundación Santa Fe de Bogotá. Los desenlaces de morbilidad asociada al procedimiento fueron caracterizados, indicando que las principales causas de morbilidad son los eventos tromboticos y las infecciones. Se caracterizaron como estadísticamente significativos para estancia hospitalaria el requerimiento transfusional (r=0,451, p=0,001), colecistectomía (p=0,016), el riesgo anestésico ASA≥3 (p=0,03), entre otros. El perfil de infección mostró relación estadísticamente significativa con resecciones de órganos específicas (p<0,05 para colectomía derecha [OR=5,3], colecistectomía [OR=21,8] y esplenectomía [OR=4,2]), el riesgo anestésico ASA≥3 (OR=1,2, p=0,036), anemia (OR=7,1, p=0,004), fístula (OR=5,2, p=0,036), entre otros. Conclusiones: El procedimiento de Sugarbaker es eficaz y seguro en nuestra institución. Se requiere de más estudios en poblaciones diversas que permitan comprender el comportamiento de las infecciones en la población sometida al procedimiento.

Adenocarcinoma de apêndice: Relato de dois casos e revisão da literatura

Background: The adenocarcinoma of the appendix is a rare disease, generally identified as an acute appendicitis in the clinical presentation. Preoperative diagnosis is extremely difficult and uncommon. Objective: To present two cases of adenocarcinoma of the appendix, unique for presenting in early ages, and a complete literature review on this topic. Cases report: First case: a 24-year-old man submitted to appendectomy for acute inflammatory abdomen. Sent to hospital due to a histopathological diagnosis of mucinous adenocarcinoma of the appendix. Right hemicolectomy, epiploectomy, ganglion and partial abdominal wall resection were performed. The patient is now in chemotherapy. Second case: a 32-year-old man presented, during appendectomy, with vegetant lesion on the apex of the appendix. The histopathological study revealed the presence of adenocarcinoma of the appendix. Right hemicolectomy with ganglion resection was performed. The patient does not present signs of recurring disease. Conclusion: The macroscopic and clinical similarity between adenocarcinoma of the appendix and acute appendicitis makes it important to check out histopathological study results. The cases above reinforce this requirement, as the authors have found adenocarcinoma of the appendix in young patients.

Acute coronary syndrome associated with continuous 5-fluorouracil infusion in a patient with metastatic colorectal cancer-a case report with a discussion on this clinical dilemma

Introduction: 5-Fluorouracil (5-FU) is considered to be the backbone of colorectal cancer (CRC) systemic therapy since the great majority of recommended regimens include its administration. A clinical picture consisting of chest pain, sometimes cardiac enzyme elevation, electrocardiogram abnormalities consistent with myocardial ischemia, and normal coronary angiogram associated with 5-FU administration have been infrequently reported. The clinical dilemma is: Which chemotherapy regimen should we use in CRC patients with a previous acute coronary syndrome (ACS) associated with 5-FU? Case Report: We describe the case of a 55-year-old otherwise healthy woman with metastatic colon adenocarcinoma who presented an ACS probably secondary to arterial vasospasm while receiving continuous intravenous 5-FU infusion (mFOLFOX6 regimen). After the ACS, the patient was treated with raltitrexate plus oxaliplatin (TOMOX) and subsequently with irinotecan plus cetuximab with no other cardiac event. Conclusion: The risk of cardiotoxicity associated with 5-FU is low but real. The probable mechanism is arterial vasospasm, as suggested by our case report. Both the use of the TOMOX regimen and irinotecan plus cetuximab seems to be safe regimens to be considered in this clinical scenario. © 2009 Humana Press Inc.

A study of large-bowel volvulus in urban Australia

Background: Large-bowel volvulus is a rare cause of bowel obstruction in the industrialized world. We analyzed the presentation and outcome of 49 patients at the Princess Alexandra Hospital, Brisbane, Australia, who received a diagnosis of colonic volvulus from 1991 to 2001. Methods: A retrospective chart study was carried out. Results: Twenty-nine patients had sigmoid volvulus (59%), 19 patients had cecal volvulus (39%) and 1 patient had a transverse colon volvulus (2%). The diagnosis of sigmoid volvulus was made accurately on plain abdominal radiography or contrast enema in 90% of cases (n = 26), compared with only 42% of cases (n = 8) of cecal volvulus. Twenty-two patients with sigmoid volvulus were treated initially with endoscopic decompression. The success rate was 64% (n = 14). There was a high early recurrence rate of sigmoid volvulus for those treated by endoscopic decompression alone (43%) during a mean period of 32 days. Of the 14 patients with cecal volvulus who were treated with right hemicolectomy, 12 had primary anastomosis and 2 had end ileostomy with mucous fistula formation. There was no anastomotic leak following right hemicolectomy with primary anastomosis, even though 6 of these patients had an ischemic cecum. Conclusions: Endoscopic decompression of the sigmoid volvulus was safe and effective as an initial treatment but has a high early recurrence rate. Any patient who is fit enough to undergo operation should have a definitive procedure during the same admission to avoid recurrence. Cecal volvulus is associated with a higher incidence of gangrene and is treated effectively by right hemicolectomy with or without anastomosis. The need for swift operative intervention is emphasized.

Cecal volvulus during pregnancy. Case report

Introduction. Acute intestinal obstruction in pregnancy is a rare, but life-threatening complication associated with high fetal and maternal mortality. Case report. A 20-year old gravida presented with a 24 hour history of several episodes of vomiting, complete constipation and severe crampy abdominal pain. The patient was admitted with the diagnosis of acute abdomen associated with septic shock. On examination echography showed distended intestinal loops and presence of free peritoneal fluid. Abdominal X-ray with shielding of the fetus revealed colonic air-fluid levels. The obstetrician consult diagnosed dead fetus in utero and was decided to operate immediately. On laparotomy was found complete cecal volvulus with gangrene of cecum, part of ascending colon and terminal ileum. A right hemicolectomy was performed with side to side ileotransverse anastomosis. Afterwards a lower segment cesarean section was made and a stillborn fetus was delivered. The patient made an uneventful recovery and was discharged on 9th postoperative day. Conclusion. Cecal volvulus during pregnancy is a rare, but serious surgical problem. Correct diagnosis may be difficult until exploratory laparotomy is performed. Undue delay in diagnosis and surgical treatment can increase the maternal and fetal mortality.
