Volvo do cólon transverso: uma causa rara de abdome agudo cirúrgico / Transverse colon volvulus: a rare cause of surgical acute abdomen

O volvo do cólon é uma condição cirúrgica incomum que ocorre devido a uma torção do eixo mesentérico, situação que resulta em redução parcial ou completa do trânsito intestinal. O cólon sigmóide é o segmento mais envolvido. O presente estudo descreve caso raro de abdome agudo provocado por um volvo do cólon transverso, associado a obstrução intestinal. A tomografia de abdome evidenciou importante distensão e níveis hidroaéreos nos cólons ascendente e transverso, com interposição de alça entre a cúpula diafragmática direita e o dômus hepático (Sinal de Chilaiditi). Foi submetido a laparotomia exploradora com colectomia direita extendida e anastomose íleocólica látero-lateral. O paciente apresentou boa evolução pós operatória. O diagnóstico dessa patologia nem sempre é feito com facilidade, sendo na maior parte dos casos o diagnóstico definitivo realizado no intra-operatória. (AU)

Colonic volvulus is an uncommon surgical condition that occurs due to a twisting around the mesenteric axis, which results in partial or complete reduction in intestinal transit. The sigmoid colon is the most commonly affected segment. We report a rare case of acute abdomen caused by transverse colon volvulus, associated with intestinal obstruction. Abdominal computed tomography showed significant distension and air-fluid levels in the ascending and transverse colons, with loop interposition between the liver and right hemidiaphragm (Chilaiditi's sign). The patient underwent exploratory laparotomy with extended right colectomy and side-to-side ileocolic anastomosis. The postoperative period was uneventful. Diagnosis of this condition is not always easy, and in most cases a definitive diagnosis is made intraoperatively. (AU)

Material and methods: A descriptive, observational, crosssectional study of 418 patients diagnosed with sigmoid volvulus; Admitted initially due to intestinal obstruction, in the Hospital of Juliaca Carlos Monge. Puno-Perú, during the period 2008-2012. The data were processed through the SPSS software version 21. Results: A total of 418 patients were enrolled, the mean age was 60 years, range 18-89 years, and the male/female ratio was 3.5/1. Nonsurgical management was done in 64 (15.4%), the treatment used was saline enema 20 cases (31%) and rectal catheter 44 (69%), recurrence was present in 27 patients (45%), who had surgery with primary anastomosis resection, of which the mortality corresponded to 8 patients (30%). Of the 354 patients undergoing emergency surgical management, 325 were submitted to sigmoidectomy with primary anastomosis (92%), while 29 had Hartmann's colostomy (8%), the morbidity for both procedures was 52 cases (14.7%), Mortality for both procedures was 45 cases (12.7%). Conclusions: In patients with sigmoid volvulus due to Andean megacolon the mean age was 60 years. The 15.4% had non-surgical management, the recurrence rate was 45%, and mortality 30%. Patients with surgical management was 84.7%, from this group; 92% had primary anastomosis resection and 8% Hartmann colostomy, morbidity was 14.7% and mortality was 12.7%.

Propuesta alternativa para el tratamiento del vólvulo sigmoideo / Alternative proposal for the treatment of the sigmoid volvulus

La sigmoidectomía con anastomosis primaria del colon constituye una alternativa para el tratamiento quirúrgico del vólvulo sigmoideo. Objetivo: demostrar la validez de esta técnica en pacientes seleccionados y conocer sus ventajas sobre el resto de procederes quirúrgicos a emplear.Método: se realizó sigmoidectomía con anastomosis primaria en dos planos a veintidós pacientes portadores de vólvulo sigmoideo. El estudio intervencionista longitudinal prospectivo se inició en octubre del 2003 en el Royal Victoria Teaching Hospital, La Gambia. Se concluyó en el Hospital Amalia Simoni de Camagüey en septiembre de 2007. Los datos se extrajeron de los expedientes clínicos de los pacientes al momento de su egreso hospitalario. Se procesaron en microcomputadora IBM. Se establecieron criterios de inclusión, exclusión y criterios que permitieran evaluar la eficacia del tratamiento. Se empleó antibioticoterapia preoperatoria profiláctica sistémica. Resultados: el íleo paralítico predominó como complicación.No existieron complicaciones relativas a la anastomosis primaria. No se reintervinieron pacientes ni existió mortalidad. Todos los pacientes al momento de su egreso manifestaron sentir satisfacción con el tratamiento quirúrgico realizado. Conclusiones: la técnica realizada aportó a los pacientes bienestar biopsicosocial. Aportó beneficios económicos por concepto de ahorro a las instituciones de salud y al estado. Los pacientes y familiares que económicamente dependen de estos se beneficiaron por la rápida reincorporación laboral de los mismos.

The sigmoidectomy with primary anastomosis of the colon constitutes an alternative for the surgical treatment of the sigmoid volvulus. Objective: to demonstrate the validity of this technique in selected patients and to know their advantages on the rest of surgical procedures to use. Method: sigmoidectomy with primary anastomosis in two planes to twenty-two patients carriers of sigmoid volvulus. A prospective longitudinal interventionist study began in October 2003 in Royal Victoria Teaching Hospital, Gambia and was concluded at "Amalia Simoni" Hospital of Camagüey in September 2007. Data were extracted of the clinical records from the patients at the moment of their hospital discharge. It were processed in IBM microcomputer. Inclusion, exclusion criteria that allowed evaluating the effectiveness of the treatment were established. Systemic prophylactic preoperative antibiotic-therapy was used. Results: the paralytic ileus prevailed as complication. Relative complications didn't exist to the primary anastomosis. No patients were reintervened neither mortality existed. All patients at the moment of their discharge manifested to feel satisfaction with the carried out surgical treatment. Conclusions: the carried out technique contributed to the patient biopsychosocial well-being. It contributed economic profits for saving concept to health institutions and to the state. Patients and family that economically depend of these were benefited from their quick labor reincorporation.

Acute Sigmoid Volvulus in a West African Population

BACKGROUND: Acute sigmoid volvulus is one of the commonest causes of benign large bowel obstruction. Its incidence varies considerably from one geographic area to another. OBJECTIVE: To review the management of acute sigmoid volvulus in a relatively high prevalence area. METHODS: All adult patients with acute sigmoid volvulus seen at the Royal Victoria Teaching Hospital (RVTH) Banjul; between September 2000 and January 2005 were studied. Information obtained for analysis from the records included age; sex; clinical features; test results; and outcomes. RESULTS: A total of 48 patients; 45 (93.8) males and three (6.3) females; with a male: female ratio of 14.3:1; age range of 19 to 78 years and mean age of 45.8 +17.6 years; underwent treatment for acute sigmoid volvulus. Twenty-one (43.8) of the patients were aged 40 to 59 years. Two (4.2) had rectal tube detortion followed by elective sigmoidectomy and primary anastomosis on the same admission; while 24 (50) had emergency laparotomy at which bowel decompression; onestage resection and primary anastomosis without on-table lavage was done. The rest of the patients; 22 (45.8) had gangrenous sigmoid colons at laparotomy and consequently had Hartmann's procedure done. Fourteen patients (29.1) developed wound infection and five (10.4) had prolonged ileus that was managed conservatively. There was no anastomotic leak. The mean hospital stay was 11.1 days. There were five deaths giving a mortality rate of 10.4. CONCLUSION: Acute sigmoid volvulus in the Gambia is almost exclusively a male disease. Sigmoid colectomy and primary anastomosis can be carried out safely in those with viable colon without on-table colonic lavage
