Successful management of evisceration occurred after exploratory laparotomy for bilateral ovarian micropapillary serous borderline tumors

Micropapillary serous borderline tumor of the ovary is characterized by a more frequent association with extraovarian, especially invasive, implants. The aim of this study was to report the clinicopathological findings of a rare case of micropapillary serous borderline tumor of the ovary since there are less than 100 similar cases in the published literature. Additionally, the successful management of evisceration that complicated the postoperative stay of the patient is analyzed. The incidence of this severe complication is estimated between 0.29-2.3%. There are four main causes: suture tearing through the fascia, knot failure, suture failure, and extrusion of abdominal contents between sutures placed too far apart. At least 50% of the cases are due to technical error with a potentially lethal result.

Negative laparotomy in trauma: are we getting better?

One of the trauma surgeons' daily challenges is the balancing act between negative laparotomy and missed abdominal injury. We opted to characterize the indications that prompted a negative trauma exploratory laparotomy and the rate of missed abdominal injuries in an effort to optimize patient selection for laparotomy. At the Los Angeles County + University of Southern California Medical Center, negative laparotomies and missed injuries are consecutively captured and reviewed at the weekly mortality + morbidity (MM) conferences. All written reports of the MM meetings from January 2003 to December 2008 were reviewed to identify all patients who underwent a negative laparotomy or a laparotomy as a result of an initially missed abdominal injury. Over the 6-year study period, a total of 1871 laparotomies were performed, of which 73 (3.9%) were negative. The rate of missed injuries requiring subsequent laparotomy was 1.3 per cent (25 of 1871). The negative laparotomy rate and the rate of missed injuries did not vary significantly during the study period (2.8 to 4.7%, P = 0.875, and 0.7 to 2.9%, P = 0.689). Penetrating mechanisms accounted for the majority of negative laparotomies (58.9%). The primary indication for negative laparotomy was peritonitis (54.8%) followed by hypotension (28.8%) and suspicious computed tomographic scan findings (27.4%). The complication rate after negative laparotomy was 14.5 per cent, and of these, 10.1 per cent were directly related to the procedure. A low but steady rate of negative laparotomies and missed abdominal injuries after trauma remains. Negative laparotomies and missed abdominal injuries when they occur are still associated with significant complication rates and a prolonged length of stay.

A Rare Abdomino-Pelvic Tumor: Paraganglioma

Paragangliomas are rare tumors, with a reported incidence of 2–8 per million. They are chromaffin cell tumors that develop from the neural crest cells and may be divided in tumors derived from the parasympathetic or sympathetic ganglia. We report a case a of a 32-year-old nulliparous woman, referred to our Infertility Clinic. Abdomino-pelvic ultrasound identified a large abdominopelvic tumor, without ovarian origin (both ovaries were identified and had normal morphology). Magnetic Resonance Imaging suggested a right adnexal multicystic, vascularized mass close to iliac vessels and questioning an ovarian origin. At exploratory laparotomy, a 10 cm encapsulated and vascularized mass was found beginning just below right renal artery and extending to the level of the broad ligament. This mass was totally excised and histopathology was consistent with Paraganglioma.

Análisis de la calidad en la atención del paciente de cirugía general de urgencia

Objetivo: proponer un instrumento para el seguimiento de la calidad de la atención de pacientes con patologías quirúrgicas abdominales urgentes. Métodos: se revisaron restropectivamente historias clínicas de pacientes quienes requirieron cirugía general de urgencia (CGU) en agosto de 2013. Se analizaron variables demográficas, factores de riesgo, severidad y desenlace hasta el día 30 postoperatorio. Se incluyeron los indicadores de calidad del National Surgical Quality Improvement Program (NSQIP) y el National Trauma Data Bank, y se adicionaron otros. Resultados: Se intervinieron 231 pacientes de 261 procedimientos de CGU. La edad promedio fue 49 años. Los procedimientos más comunes fueron la colecistectomía laparoscópica (37.2%), la apendicectomía (35.6%), la laparotomía exploratoria (12.6%), el drenaje de colección abdominal (9.1%) y la liberación de adherencias (6.9%). La mortalidad fue de 3.46% (n=8), la morbilidad severa fue de 8.04%. La duración de la hospitalización fue de 6.54 días +/- 5.180 y la de hospitalización en Unidad de Cuidado Intensivo fue de 5.7 días +/- 4.42. La oportunidad de salas de cirugía para la apendicetomía fue de 5 horas para las apendicitis con peritonitis generalizada, y de 8 horas para las apendicitis localizadas, 37 horas para colecistitis, 7.48 horas para colangitis y 2.42 horas para diverticulitis. Conclusiones: Crear de un instrumento para la medición de la calidad de la atención de los pacientes en CGU, es necesario para la autoevaluación institucional y para definir planes de mejoramiento y distribución de los recursos.

Influência da aboragem cirúrgica (laparotomia versus vedeolaparoscopia na gestação : estudo experimental em coelhas

Objetivo: Estudar a influência de duas abordagens cirúrgicas na evolução da gestação de coelhas prenhes. Delineamento: Estudo experimental e controlado. Método: Sessenta coelhas brancas, da raça Nova Zelândia (Oryctolagus cuniculus), prenhes, foram divididas em três grupos de estudo: controle (n=20), laparotomia (n=20) e videolaparoscopia (n=20). Os três grupos, após anestesia intravenosa e intubação orotraqueal, foram submetidos a duas diferentes abordagens cirúrgicas (laparotomia exploradora e videolaparoscopia diagnóstica) e acompanhados até o momento do parto. Foram feitas observações referentes à duração da gestação, da mortalidade fetal e do peso dos láparos vivos. Foram coletadas amostras de sangue arterial, no período pré e pós-operatório, para análise gasométrica e medidas do hematócrito e da hemoglobina das coelhas. Resultados: A duração da gestação (31,6 ± 0,99 vs. 31,8 ± 1,8 vs. 31,3 ± 2,24 dias), a taxa de mortalidade fetal (1,0 ± 2,5 vs. 1,9 ± 2,7 vs. 1,4 ± 2,0) e o peso dos láparos vivos no primeiro dia de vida (48,7 ± 11,3 vs. 51,5 ± 11,9 vs. 48,3 ± 8,2 g) nos grupos C, L e V, respectivamente, não apresentaram diferenças estatísticas significativas entre os grupos de estudo (p>0,05). Nas análises das amostras sangüíneas, quando comparado as diferenças entre o pré e o pós-operatório entre os grupos L e V, respectivamente, foram encontradas diferenças com relevância estatística (p>0,05) em relação às medidas do hematócrito (34,4 ± 3,1 e 33,1 ± 2,8 vs. 34,2 ± 3,2 e 30,3 ± 3,7), do pH (7,4 ± 0,1 e 7,4 ± 0,1 vs. 7,5 ± 0 e 7,3 ± 0,1), do paCO2 ( 30,8 ± 5,1 e 40,7 ± 8,2 vs. 32 ± 3,7 e 53,5 ± 18,4), mas sem relevância clínica. Conclusão: A evolução da gestação das coelhas prenhes submetidas a abordagens videolaparoscópica e laparotômica não mostrou diferença entre os grupos, estando ambas as técnicas indicadas no período gestacional de coelhas quando se fizer necessário.

Rectal atresia in a newborn donkey

P>A case of a type I rectal atresia (also known as membranous rectal atresia) in a newborn donkey is reported. Clinical examination, survey radiographs and barium enema radiographs suggested rectal atresia. An exploratory laparotomy was performed; however, surgical correction of the defect was not possible due to the narrow pelvic cavity. Euthanasia was performed. At necropsy, it was possible to observe a fibrous cord connecting the small colon to a residual rectal ampulla, which opened to a normal anus. The radiographic and anatomical characteristics enabled the classification of the defect as type I rectal atresia, which is a rare congenital anomaly that is difficult to correct through surgery. This report contributes to the study of rectal atresia in newborn equids, alerts for the occurrence in donkeys and is, to our knowledge, the first to be reported in this species in Brazil.

Gastric Torsion from an Intestinal Hernia Through a Rent in the Gastrosplenic Ligament in a Horse

The present report describes an 8-year-old gelding presenting with signs of severe abdominal pain. After performing a thorough physical examination, including rectal palpation and additional diagnostic tests, an exploratory laparotomy was recommended. The jejunum was found herniated through the gastrosplenic ligament, and the stomach was severely distended with gas. Given a poor prognosis, the horse was euthanized on the table. At necropsy, the stomach appeared dilated, with an 180 horizontal gastric torsion, from left (lateral) to right (medial), dividing the organ into dorsal and ventral compartments. We believe that the chronic traction exerted by an incarcerated and distended loop of jejunum, in the dorsal aspect of the gastrosplenic ligament, associated with trauma during episodes of intense rolling, enlarged the rent until it ruptured. Because of this rupture, the lateral dorsal aspect of the stomach became unattached, predisposing it to the torsion. (C) 2012 Elsevier B.V. All rights reserved.

Disseminated Transmissible Venereal Tumour Associated With Leishmaniasis in a Dog

This report addresses an atypical transmissible venereal tumour in an 8-year-old bitch that was pluriparous and seropositive for leishmaniasis. There were ascites and a serosanguineous discharge from the vulva, but no lesions on the external genital mucosa. An aspirate of the peritoneal fluid showed mononuclear round cells characteristic of transmissible venereal tumour (TVT). Exploratory laparotomy revealed light red, granulomatous structures in the peritoneum, omentum, spleen, liver and uterine horns. Cytological and histopathological tests confirmed the diagnosis of intra-abdominal TVT. Dissemination of the TVT to several organs inside the abdominal cavity probably resulted from immunosuppression caused by leishmaniasis, which favoured the presence and aggressiveness of TVT.

Mummified papyraceous fetuses in the abdominal cavity of an elderly female dog with pyometra

This paper reports on a rare case of fetal papyraceous mummification after asymptomatic uterine rupture in an elderly female dog with pyometra. The patient had a history of mating six months before the examination but no apparent signs of gestation or parturition. Exploratory laparotomy was used to identify a rupture of the left uterine horn and the presence of cystic endometrial hyperplasia and pyometra. Two mummified papyraceous fetuses were observed in the abdominal cavity and had adhered to the spleen, pancreas, intestine and omentum. Ovariehysterectomy and corrective surgery were performed. The patient had remained healthy after uterine rupture until a new estrous cycle and the development of pyometra. Bitches that are 10 years old or more are predisposed to implantation failure, pregnancy or parturition problems and they should not be breed to avoid complications.

Raquianestesia contínua em paciente submetido à gastrectomia parcial. Relato de caso

BACKGROUND AND OBJECTIVES: Due to the high incidence of technical and neurological complications, continuous spinal blocks were not performed for several years. With the advent of intermediate catheters the technique has been used more often and gaining acceptance among anesthesiologists. The objective of this report was to demonstrate the usefulness of the technique as a viable alternative for medium and major size surgeries. CASE REPORT: This is a 58 years old female patient, weighing 62 kg, physical status ASA I, with a history of migraines, low back pain, and prior surgeries under spinal block without intercurrence. The patient was scheduled for exploratory laparotomy for a probable pelvic tumor. After venoclysis with an 18G catheter, monitoring with cardioscope, non-invasive blood pressure and pulse oximetry was instituted; she was sedated with 2 mg of midazolam and 100 μg of fentanyl, and placed in left lateral decubitus. The patient underwent continuous spinal block through the median approach in L 3-L 4; 9 mg of 0.5% hyperbaric bupivacaine and 120 μ g of morphine sulfate were administered. Inspection of the abdominal cavity revealed a gastric stromal tumor that required an increase in the incision for a partial gastrectomy. A small dose of hyperbaric solution was required for the entire procedure, which was associated with complete hemodynamic stability. Postoperative admission to the ICU was not necessary; the patient presented a good evolution without complaints and with a high degree of satisfaction. She was discharged from the hospital after 72 hours without intercurrence. CONCLUSIONS: Intermediate catheters used in continuous spinal blocks have shown the potential to turn it an attractive and useful technique in medium and large size surgeries and it can even be an effective alternative in the management of critical patients to whom hemodynamic repercussions can be harmful.

Intussuscepção ileocólica associada a torção mesentérica em um cão: Relato de caso

Mesenteric torsion is a rare disease in dogs whereas it is more common to affect large animals. The main clinical signs observed are acute, such as prostration and abdominal distension which evolve to a state of shock and death. This paper reports the mesenteric torsion in a dog that was presented to veterinary care with generalized acute abdominal pain of sudden onset. At the physical examination, signs of acute abdomen, rectal temperature of 35 oC, moderate dehydration, congested mucous membrane, and prostration were detected. Emergency therapy was instituted and radiographic and ultrasound examinations were requested. The radiography showed increase in the bowel diameter and an image suggestive of intussusception. The patient was referred to emergency exploratory laparotomy and obtained a definite diagnosis of ileocolic intussusception associated to mesenteric torsion. Due to the extent of intestinal dysfunction, the patient was euthanized on the operating table.

Transrectal bladder prolapse secondary to pelvic fracture in two dogs

This report describes the exteriorisation of the urinary bladder in two dogs as a result of a laceration of the rectum from a traumatic pelvic fracture. Clinical examination and contrast radiography of the bladder were used as diagnostic tools. Both patients were treated with exploratory laparotomy, where traction of the bladder was utilised to pull the bladder through the traumatic rectal laceration allowing the organ to return to its normal anatomical position. This procedure was followed by surgical reconstruction of the rectum, resulting in effective resolution of each case.

Nefroblastoma em cão de 4 meses: relato de caso

Renal nephroblastoma is a malignant tumor composed by embryonic tissue that affects mainly puppies. This works reports the occurrence of unilateral renal nephroblastoma in a puppy with four months. The diagnosis was obtained by histopathological examination of mass obtained by exploratory laparotomy, with realization of nephrectomy. The animal died at 15 days post-operatively by the presence of pulmonary metastases. The survival rate with surgical excision of the mass, with or without complementary therapies, can vary with the stage of disease.
