ABSTRACT
INTRODUCTION: Small bowel obstruction (SBO) is one of the most common causes for hospital admission in Ethiopia. The use of water-soluble contrast agents (WSCAs) such as Gastrografin to manage adhesive SBO can predict nonoperative resolution of SBO and reduce decision time to surgery and length of hospital stay. However, nothing is known about practice patterns and Gastrografin use in low-income settings. We sought to characterize current management practices, including use of WSCAs, as well as outcomes for patients with SBO in Addis Ababa, Ethiopia. METHODS: We conducted a mixed-methods study consisting of a survey of surgeons throughout Ethiopia and a retrospective record review at five public, tertiary care-level teaching hospitals in Addis Ababa. RESULTS: Of the 76 surgeons who completed the survey, 63% had heard of the use of WSCAs for SBO and only 11% used oral agents for its management. Chart review of 149 patients admitted with SBO showed the most common etiology was adhesion (39.6% of admissions), followed by small bowel volvulus (20.8%). Most patients (83.2%) underwent surgery during their admission. The most common diagnosis in patients who did not require surgery was also adhesion (68.0%), as well as for those who had surgery (33.9%), followed by small bowel volvulus (24.2%). CONCLUSIONS: The etiology of SBO in Ethiopia may be changing, with postoperative adhesions becoming more common than other historically more prevalent causes. Although a Gastrografin protocol as a diagnostic and potentially therapeutic aid for SBO is feasible in this population and setting, challenges can be anticipated, and future studies of protocol implementation and effectiveness are needed to further inform its utility in Ethiopia and other low-income and middle-income countries.

AIM: Reporting of participant descriptors in studies of adhesive small bowel obstruction (ASBO) can help identify characteristics associated with favourable outcomes and allow comparison with other studies and real-world clinical populations. The aim was to identify the pattern of participant descriptors reported in studies assessing interventions for ASBO. METHOD: This systematic review was registered with PROSPERO (CRD42021281031) and reported in line with the PRISMA checklist. Systematic searches of Ovid MEDLINE, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) were undertaken to identify studies assessing operative and non-operative interventions for adults with ASBO. Studies were dual screened for inclusion. Descriptors were categorised into conceptual domains by the research team. RESULTS: Searches identified 2648 studies, of which 73 were included. A total of 156 unique descriptors were identified. On average, studies reported 12 descriptors. The most frequently reported descriptors were sex, age, SBO aetiology, history of abdominal surgery, BMI and ASA classification. The highest number of descriptors in a single study was 34, compared to the lowest number of descriptors which was one. Pathway factors were the least frequently described domain. Overall, 37 descriptors were reported in just one study. CONCLUSION: There is a lack of consistency in participant descriptors reported in studies of SBO. Furthermore, a significant proportion of the descriptors were used infrequently. This makes it challenging to assess whether study participants are representative of the wider population. Further work is required to develop a Core Descriptor Set to standardise the reporting of patient characteristics and reduce heterogeneity between studies.

BACKGROUND: Adult mechanical bowel obstruction (AMBO) has been previously reported to be majorly caused by hernias in developing countries. In Nigeria, however, there has been a recent change in pattern with adhesions now being the leading cause. The aim of this systematic review is to examine the changing pattern of the causes, and outcomes of patients managed for AMBO in Nigeria. METHODS: Relevant keywords relating to AMBO were used to conduct a search on PubMed, Web of Science, Google Scholar, and AJOL. The search returned 507 articles, which were subjected to title, abstract, and full text screenings, according to the inclusion and exclusion criteria. This generated 10 articles which were included in the final qualitative synthesis. RESULTS: The total sample size across the 10 studies was 1033. Adhesions, hernias, and intra-abdominal tumors, responsible for 46.25%, 26.31%, and 12.23% of cases respectively, were the major causes of AMBO in Nigeria. 65.6% of cases were managed operatively and 34.4% were managed conservatively. The meta-analysis revealed high morbidity and mortality rates of 31% (95% CI: 17; 44, 5) and 11% (95% CI: 6; 15, 5), respectively, among adult patients managed for mechanical bowel obstruction in Nigeria. CONCLUSIONS: Adhesion, which results predominantly from appendicectomy is the most common cause of AMBO in Nigeria. This is unlike former reports where hernia was the most common cause. Morbidity results majorly from wound infection, recurrent adhesions, and postoperative enterocutaneous fistula. The mortality rate is similar to reports from various West African studies, and it is significantly influenced by surgical intervention time.

BACKGROUND: Both the trauma of endometrium and hysteroscopic adhesiolysis can lead to a high rate of placenta accreta spectrum (PAS) in women with intrauterine adhesion (IUA). This study analysed the impact of time interval from adhesiolysis to pregnancy on PAS in IUA women. METHODS: Patients diagnosed with IUA who underwent adhesiolysis in Anhui Women and Children's Medical Centre between January 2016 and December 2020 were included in this case-series study. Clinical data were obtained from electronic medical records and telephone interviews. RESULTS: Among a total of 102 IUA women with successful pregnancies, 8 (7.8%) suffered from miscarriages with PAS, and 94 (92.2%), 47 with PAS and 47 without PAS, had successful delivery. The total prevalence of PAS in pregnant women with IUA was 53.9% (55/102). The average time from adhesiolysis to pregnancy in the PAS group was significantly longer than in the non-PAS group (14.2 ± 5.7 vs. 10.3 ± 4.4 months, p = 0.000). Regression analysis showed that AFS grade (OR = 7.40, 95% CI 1.38-39.73, p = 0.020) and adhesiolysis to pregnancy interval time between 12 and 24 months (OR = 12.09, 95% CI 3.76-38.83, p = 0.000) were closely related to PAS. A Kaplan-Meier analysis showed the median interval time to PAS was 16.00 months (95% CI 15.11-16.89). CONCLUSIONS: We assume that prolonged adhesiolysis to pregnancy interval may be considered a significant risk factor for PAS in IUA women.

Background: Patients with prior abdominal surgeries are at higher risk for intra-abdominal adhesive tissue formation and subsequently higher risk for small bowel obstruction (SBO).Purpose: In this study, we investigated whether surgical intervention for SBO was more likely following specific types of abdominal surgeries.Research Design: With retrospective chart review, we pooled data from 799 patients, ages 18 to 89, admitted with SBO between 2012 and 2019. Patients were evaluated based on whether they underwent surgery or were managed conservatively. They were further compared with regard to past surgical history by way of type of abdominal surgery (or surgeries) undergone prior to admission.Results: Of the 799 patients admitted for SBO, 206 underwent surgical intervention while 593 were managed nonoperatively. There was no significant difference in number of prior surgeries (2.07 ± 1.56 vs 2.36 ± 2.11, P = .07) or in number of comorbidities (2.39 ± 1.97 vs 2.65 ± 1.93, P = .09) for surgical vs non-surgical intervention. Additionally, of the operations evaluated, no specific type of abdominal surgery predicted need for surgical intervention in the setting of SBO. However, for both surgical and non-surgical intervention following SBO, pelvic surgery was the most common type of prior abdominal surgery (45% vs 43%). There are significantly more female pelvic surgeries in both the operative (91.4% vs 8.6%, P < .0001) and nonoperative groups (89.9% vs 10.2%, P < .0001).Conclusion: Ultimately, no specific type of prior operation predicted the need for surgical intervention in the setting of SBO.

The adoption of laparoscopy for the management of adhesive small bowel obstruction (ASBO) patients is debated. The laparoscopic approach has been associated with a considerable conversion-to-open rate. Nonetheless, reliable predictors of conversion are still unclear. The present study aimed to identify factors associated with conversion to open in ASBO patients who underwent laparoscopic surgery. Patients who underwent laparoscopic surgery for ASBO and were admitted to our unit between December 2014 and October 2022 were retrospectively evaluated. The patients were categorized into two groups: patients who underwent complete laparoscopy approach (Group 1) and patients converted to open technique (Group 2). Demographic, clinical, and radiological features, intraoperative findings, and postoperative outcomes were compared. A total of 168 patients were enrolled: 100 patients (59.5%) were included in Group 1, and 68 patients (40.5%) were included in Group 2. The rate of ischemia (p = 0.023), surgical complications (p = 0.001), operative time (p < 0.0001), days of nasogastric tube maintenance (p < 0.0001), time to canalization (p < 0.0001), and length of hospital stay (p < 0.0001) were significantly higher in Group 2 than Group 1. Following univariate analysis, the presence of feces signs (p = 0.044) and high mean radiodensity of intraperitoneal free fluid (p = 0.031) were significantly associated with Group 2 compared with Group 1. Following multivariate analysis, the feces sign was a significant predictive factor of conversion (OR 1.965 [IC 95%]; p = 0.046). Laparoscopic treatment is a safe and effective approach in patients affected by ASBO. The feces sign may be a predictive factor of conversion and could guide the surgeon in selecting the appropriate management of patients affected by ASBO.

OBJECTIVE: To identify the predictive factors of intestinal ischaemia in adhesive small bowel obstruction (ASBO) and develop an intestinal ischaemia risk score. STUDY DESIGN: Observational study. Place and Duration of the Study: Department of General Surgery, Shandong Provincial Qianfoshan Hospital, Jinan, Shandong, China, from January 2017 to February 2022. METHODOLOGY: ASBO was determined by findings at laparotomy. The assessment of small bowel's viability was conducted through surgical inspection and subsequent histological examination of the surgical specimen. Univariate and multivariate analyses were conducted to ascertain the risk factors associated with intestinal ischaemia. RESULTS: In total, 79 patients were included. Factors entered into multivariate analysis associated with intestinal ischaemia were; rebound tenderness (odds ratio (OR): 7.8, 95% confidence interval (CI):1.7-35.3; p=0.008), procalcitonin (PCT) >0.5 ng/mL (OR: 11.7, 95% CI: 2.3-58.1; p=0.003), and reduced bowel wall enhancement on computerised tomography (CT) scan (OR: 12.2, 95% CI:2.4-61.5; p=0.003). Among patients with 0, 1, 2, and 3 factors, the rate of intestinal ischaemia increased from 0% to 49%, 72%, and 100%, respectively. According to the number of risk factors, the area under the receiver operating characteristic curve for the determination of intestinal ischaemia was 0.848 (95% CI: 0.764-0.932). CONCLUSION: Rebound tenderness, PCT levels >0.5 ng/mL, and reduced bowel wall enhancement are risk factors of intestinal ischemic injury that require surgery within the context of ASBO. These factors need to be closely monitored that could assist clinicians in avoiding unnecessary laparotomies and selecting patients eligible for surgery. KEY WORDS: Intestinal obstruction, Ischaemia, Adhesions.

OBJECTIVE: Complicated appendicitis is associated with a higher risk of postoperative complications, including adhesive bowel obstruction. The aim of this meta-analysis is to investigate the difference in rates of postoperative bowel obstruction in paediatric patients with complicated versus simple appendicitis and whether this is influenced by the surgical approach. METHODS: A systematic literature search following PRISMA guidelines was conducted using MEDLINE, Embase and Cochrane Library for studies that analysed incidence of adhesive bowel obstruction in paediatric patients after appendicectomy. Studies from 1998 to 2022 were included in analysis. The study protocol was registered on PROSPERO (ID CRD42022309769). RESULTS: Pooled analysis of 6 studies with low risk of bias and adequate follow up periods, considering 58,962 cases of appendicectomy, revealed complex appendicitis was associated with a near two-fold increase in incidence of SBO (pooled odds ratio 2.02 (95% CI 1.35-2.69)). Interestingly, a similar pooled analysis of 10 studies, considering 62,433 cases of appendicectomy, revealed no significant difference between open and laparoscopic management of complex appendicitis (pooled odds ratio 0.93 (95% CI 0.24 to 1.62)). CONCLUSION: Complex appendicitis is associated with a two-fold increase in the rates of adhesive bowel obstruction. Whilst there are cosmetic advantages of a laparoscopic approach, surgical expertise should be favoured in decision making relating to surgical approach (laparoscopic versus open) as the evidence for a laparoscopic approach reducing risks of adhesive bowel obstruction is not convincing. LEVEL OF EVIDENCE: Level II.

A rare condition, sclerosing encapsulating peritonitis, is characterized by a fibrotic membrane forming over the bowels, leading to intestinal obstruction. In this case of a 56-year-old male patient with a history of laparoscopic gastric bypass, a computed tomography scan showed findings indicative of the condition. Extensive adhesiolysis was performed, and biopsies confirmed the presence of fusiform cells (D2-40 positive on immunochemistry) resembling fibroblasts, within dense collagenous peritoneal tissue sheets, typical of sclerosing encapsulating peritonitis. The prevalence of this condition is uncertain, and diagnosis typically requires a peritoneal biopsy due to the nonspecific clinical presentation.
La peritonitis esclerosante encapsulada es una condición rara caracterizada por una membrana fibrótica que se genera sobre las asas intestinales causando cuadros de oclusión intestinal. Se presenta el caso de un paciente varón de 56 años con antecedente de derivación gastroyeyunal por laparoscopia que presenta oclusión intestinal. Se realizó tomografía computada que evidenció sitio de transición previo al sitio de anastomosis. Se realizó de anastomosis extensa y toma de biopsias. Histológicamente se observó engrosamiento de la membrana peritoneal, células fusiformes (D2-40 positivo en inmunohistoquímica) similares a fibroblastos con láminas de colágeno peritoneal denso. La peritonitis esclerosante encapsulada es una patología de prevalencia desconocida. El cuadro clínico es inespecífico y el diagnóstico definitivo es por patología con biopsia peritoneal.

BACKGROUND: Acute small intestinal obstruction is a common surgical emergency in the sub-Saharan region. Over the decades, complicated inguinal hernias have been identified as a leading cause. However, we observed from our clinical practice that complicated inguinal hernias were not the most common etiology. AIMS AND OBJECTIVES: This study aimed to evaluate the common etiology of acute small bowel obstruction in the study center and compare our findings with that from other centers and existing literature. MATERIALS AND METHODS: This was a retrospective, cross sectional study carried out over a period of five years (January 2017 to December 2021). This study looked at the patients presenting with acute, mechanical, small bowel obstruction that did not respond to conservative treatment in our hospital facility. Relevant information were extracted from patients' clinical details and entered into the proforma prepared for this study. RESULTS: A total of 147 patients were recruited into this study out of which 85(57.8%) were males and 62 (42.2%) were females (M:F=1.44:1). Majority (80.3%) of the patients that presented with post-operative bowel adhesion had previous appendectomy. Simple bowel obstruction was seen in 93 (63.3%) patients while strangulated obstruction and gangrenous bowel were seen in 26 (17.7%) patients and 22 (15.0%) patients respectively. Majority (47.6%) of the patients had adhesiolysis done while others had bowel resection. CONCLUSION: The common cause of acute small bowel obstruction as observed in this study is post-operative adhesions arising from previous appendectomy and laparotomies.
Résumé Contexte:Une faible obstruction intestinale a une urgence chirurgicale commune dans la région sub-saharienne. Au cours des décennies, des hernies inguiniques compliquées ont été identifiées comme une cause de premier plan. Cependant, nous avons observé de notre pratique clinique selon laquelle des hernies inguinales compliquées n'étaient pas l'étiologie la plus commune.Objectifs et objectifs:Cette étude visait à évaluer l'étiologie commune de l'obstruction aiguë aux petites interses dans le centre d'études et de comparer nos constatations avec celle d'autres centres et de la littérature existante.Matériaux et méthodes:C'était une étude rétrospective en coupe transversale réalisée sur une période de cinq ans (janvier 2017 à 2021). Cette étude a examiné les patients présentant une obstruction aiguë, mécanique et petite intestinale qui ne répondait pas au traitement conservateur dans notre installation hospitalière. Des informations pertinentes ont été extraites des détails cliniques des patients et ont conclu dans la proforma préparé pour cette étude.Résultats:Un total de 147 patients ont été recrutés dans cette étude dont 85 (57,8%) étaient des hommes et 62 (42,2%) étaient des femelles (M: F = 1.44: 1). La majorité (80,3%) des patients présentés par l'adhésion intestinale post-opératoire avaient une annexe antérieure. Un obstruction d'intestin simples a été observée dans des patients de 93 (63,3%) alors que l'obstruction étrangère et l'intestin gangreneux ont été observés dans des patients de 26 (17,7%) et respectivement respectivement les patients de 22 (15,0%). La majorité (47,6%) des patients avaient une adhésiose faite pendant que d'autres avaient une résection de l'intestin.Conclusion:La cause commune de l'obstruction aiguë aux petites interses comme observé dans cette étude est des adhérences post-opératoires découlant de l'appendecectomie et des laparotomies précédentes.

OBJECTIVE: Small bowel obstruction (SBO) is a common and important surgical emergency. Our aim in this study is to describe the clinical, laboratory, and computed tomography (CT) findings to facilitate the objective identification of SBO patients in need of operative treatment in this patient population. METHODS: This retrospective study included 340 patients hospitalized due to a preliminary diagnosis of ileus. Retrieved data of patients included age, gender, comorbidities, previous hospitalization due to ileus, surgical history, physical examination findings, complete blood count and biochemistry test results, and CT findings at admission. RESULTS: The study included 180 (52.9%) male and 160 (47.1%) female patients. Treatment was conservative in 216 patients and surgery in 124 patients. Of the patients included in the study, 36.4% needed surgery. Of the female patients, 38.90% received conservative treatment and 61.30% underwent surgery. Adhesions were the most common cause of obstruction in operated patients (43.50%). CONCLUSION: We have found that female gender, vomiting, guarding, rebound, C-reactive protein levels above 75 mg/L, increased bowel diameter, and a transition zone on CT images indicate a strong need for surgery, but a history of previous hospitalization for ileus may show that surgery may not be the best option.
OBJETIVO: Describir los hallazgos clínicos, de laboratorio y de tomografía computarizada (TC) para facilitar la identificación objetiva de los pacientes con obstrucción del intestino delgado que necesitan tratamiento quirúrgico. MÉTODO: Este estudio incluyó 340 pacientes. Los datos obtenidos fueron edad, sexo, comorbilidad, hospitalización previa debida a íleo, historia quirúrgica, hallazgos de la exploración física, hemograma completo y resultados de las pruebas bioquímicas, y hallazgos de la TC al ingreso. RESULTADOS: El estudio incluyó 180 (52.9%) varones y 160 (47.1%) mujeres. El tratamiento fue conservador en 216 pacientes y quirúrgico en 124 pacientes. De los pacientes incluidos en el estudio, el 36.4% necesitaron cirugía. De las mujeres, el 38.90% recibieron tratamiento conservador y el 61.30% se sometieron a cirugía. CONCLUSIONES: Encontramos que el sexo femenino, los vómitos, la guardia, el rebote, los niveles de proteína C reactiva superiores a 75 mg/l, el aumento del diámetro intestinal y una zona de transición en las imágenes de TC indican una fuerte necesidad de cirugía.

BACKGROUND: Bowel obstruction is a disorder in the passage of bowel contents, the etiology of which varies depending on temporal and geographical conditions. This study investigated the etiology of bowel obstruction in a large number of patients at an adult surgery referral center in southern Iran. METHODS: In this cross-sectional study, we reviewed the medical records of all patients admitted to Shahid Faghihi hospital (Shiraz, Iran) between 2014 and 2020 with a diagnosis of small or large bowel obstruction. Patients with missing or obscure data on etiology were excluded. Data was collected on the patients' age, gender, history of relevant surgeries, comorbidities, cause of obstruction, site/type of obstruction, treatment, intensive care unit (ICU) admission, length of hospital stay, and outcome. Statistical analyses were made using SPSS v. 25.0. RESULTS: A total of 2781 bowel obstruction patients (61.4% males, 38.6% females) with a median age of 58 (IQR 43-71) years were studied. Most responded to non-surgical treatment (61.3%). While the obstruction was mostly partial (65.5%), 94.4% of patients with complete obstruction required surgery. Small bowel obstruction (SBO) was almost three times more prevalent than large bowel obstruction (LBO). Adhesion bands were the leading cause of SBO (66.77%), while LBO was primarily due to colorectal tumors (33.9%). CONCLUSION: The predominant etiology of LBO was colorectal cancer, suggesting that policymakers should improve surveillance programs to detect the condition earlier. Regarding SBO, the leading cause was adhesion bands, indicating the necessity of further efforts to reduce the rate of adhesions following intra-abdominal operations.

INTRODUCTION: Intestinal obstruction due to flanges is common in patients with a surgical history. OBJECTIVE: Describe a clinical case with adherenciolysis. Surgery could not be performed, so pneumoperitoneum was used as pre-conditioning for elective surgery. CLINICAL CASE: Patient with intestinal obstruction due to flanges, with impossibility of performing an adherenciolysis, for which catheters are installed to administer progressive pneumoperitoneum in order to optimize the release of flanges in elective surgery, undergoing the postoperative period with enterocutaneous fistula that required multidisciplinary management with percutaneous drainage, parenteral nutrition and nursing care, with a successful result. DISCUSSION: In a flange obstruction, an extensive adherenciolysis is often required, which carries a greater risk of intestinal injury and enterocutaneous fistula. In this case, we believe that it decreased due to the pneumoperitoneum used to generate more lax and manageable flanges. CONCLUSION: Postoperative flanges generate significant morbidity and its surgical management requires an adherenciolysis that may be laborious or impossible in the first instance, requiring in this case the use of progressive pneumoperitoneum for complete flange release, a technique not described in the literature for this purpose.
INTRODUCCIÓN: La obstrucción intestinal por bridas es frecuente en pacientes con antecedentes quirúrgicos. OBJETIVO: Describir un caso clínico con adherenciolisis frustra por cirugía, utilizando neumoperitoneo como preacondicionamiento para cirugía electiva. CASO CLÍNICO: Paciente con obstrucción intestinal por bridas, con imposibilidad de adherenciolisis, por lo que se instalan catéteres para administrar neumoperitoneo progresivo con el fin de optimizar la liberación de bridas en cirugía electiva, cursando en el postoperatorio con fístula enterocutánea que requirió manejo multidisciplinario con drenaje percutáneo, nutrición parenteral y cuidados por enfermería, que finalmente resultó exitoso. DISCUSIÓN: En una obstrucción por bridas muchas veces se requiere una adherenciolisis extensa que conlleva mayor riesgo de lesión intestinal y fístula enterocutánea, que en este caso creemos que disminuyó debido al neumoperitoneo utilizado para generar bridas más laxas y manejables. CONCLUSIÓN: Las bridas postoperatorias generan morbilidad importante y su manejo quirúrgico requiere adherenciolisis que puede resultar laboriosa o imposible en primera instancia, requiriendo en este caso el uso de neumoperitoneo progresivo para la liberación de bridas completa, técnica no descrita en la literatura para este fin.

Resumen: La obstrucción duodenal congénita agrupa un amplio espectro de anomalías en el desarrollo del intestino delgado; se clasifica según su etiología tanto en extrínseca como intrínseca. Su presentación es relativamente común, teniendo una incidencia de 1: 2.500-10.000 nacidos vivos y normalmente presenta asociación con aneuploidías (como la trisomía 21) y malformaciones cardíacas. Las imágenes tienen un papel importante en la aproximación diagnóstica y la radiografía de abdomen simple, es el primer escalón en la aproximación de la obstrucción intestinal. El tratamiento involucra una exploración quirúrgica del abdomen con corrección de los defectos encontrados. Este es un reporte de caso de un neonato que presentó obstrucción duodenal congénita de etiología tanto extrínseca (malrotacion intestinal y bandas de Ladd) como obstrucción intrínseca (membranas duodenales).
Abstract: Congenital duodenal obstruction groups together a broad spectrum of abnormalities in the development of the small intestine; it is classified according to its etiology as both extrinsic and intrinsic. Its presentation is relatively common, having an incidence of 1: 2.500-10.000 live births and it is normally associated with aneuploidy (such as trisomy 21) and cardiac malformations. Images play an important role in the diagnostic approach, with simple abdominal radiography being the first step in the approximation of intestinal obstruction. The treatment corresponds to a surgical exploration of the abdomen with resolution of the defects found. This is a case report of a newborn who presented congenital duodenal obstruction of both extrinsic etiology (intestinal malrotation and Ladd bands) and intrinsic obstruction (duodenal membranes).

Introdução: Nas abdominoplastias clássicas, um resultado indesejado após o tracionamento do retalho abdominal é a ocorrência de uma retração suprapúbica, no meio da cicatriz horizontal quando esta coincide com o ponto superior da antiga cicatriz umbilical. Métodos: Foram avaliadas 45 pacientes submetidas à dermolipectomia abdominal associada à lipoaspiração de todo o abdome e flancos, com decorticação de uma área suprapúbica cerca de 5 cm acima da marcação inicial da linha de incisão, com posterior fixação na borda inferior do retalho abdominal. Resultados: Não foram observadas depressões ou necroses na região suprapúbica. Conclusão: Observamos, nos casos operados, que a presença de um coxim dermogorduroso na porção central da linha de sutura nas abdominoplastias clássicas, associada à reconstituição completa dos planos cirúrgicos e fixação deste coxim no retalho abdominal superior, evita a ocorrência de depressões nesta região, evita ocorrência de necroses e melhora a qualidade da cicatriz por redução da tensão de tração sobre os tecidos.
Introduction: In classic abdominoplasty, an undesirable result after abdominal flap traction is the occurrence of a suprapubic retraction in the middle of the horizontal scar when it coincides with the superior point of the old umbilical scar. Methods: Forty-five patients underwent abdominal dermolipectomy associated with liposuction of the entire abdomen and flanks, with decortication of the suprapubic area approximately 5 cm above the initial marking of the incision line, with posterior fixation at the lower border of the abdominal flap. Results: No depressions or necroses were observed in the suprapubic region. Conclusion: We observed that the presence of a dermofat flap in the central portion of the suture line in the classic abdominoplasties associated with the complete reconstruction of the surgical planes and the fixation of this flap in the upper abdominal flap avoids the occurrence of depressions in this region, prevents occurrence of necrosis, and improves the quality of the scar by reducing the tensile stress on the tissues.

Background: Treatment options for adhesive small bowel obstruction (ASBO) involve conservative and surgical management, traditionally through open adhesiolysis. Laparoscopic approach has been performed in recent years; however, limited data exist on its safety and results vary considerably. Our aim is to report our experience of laparoscopic treatment for ASBO. Methods: Retrospective study including patients admitted with the diagnosis of adhesive small bowel obstruction and that were submitted to laparoscopic exploration, between June 2003 and April 2013. We analyzed demographic, surgical variables and outcomes in terms of conversion rate, operative time, re-feeding time and length of stay. Non-parametric tests were used for statistical analysis. Results: Series of 38 patients submitted to laparoscopic exploration, mean age: 51 +/- 16 years, 47 percent male. 53 percent had prior intra-abdominal surgeries. Laparoscopic resolution of bowel obstruction was possible in 31 patients (82 percent), with 7 conversions to open surgery. Median operative time was 60 (25-180) minutes, median re-feeding time was 24 (24-192) hours and median length of stay was 4 (2-52) days. Two patients required re-intervention during their hospital stay, one due to persistent bowel obstruction and one due to ischemic colitis. There were no other complications or mortality. Conclusions: Laparoscopy in adhesive small bowel obstruction was a feasible approach in this series, with good results when laparoscopic resolution is achieved. Patients with no prior surgeries seem to be good candidates for this approach.
Introducción: El tratamiento de la Obstrucción Intestinal por Bridas (OIB) incluye alternativas conservadoras y quirúrgicas, esta última tradicionalmente a través de cirugía abierta. El abordaje laparoscópico ha sido incorporado recientemente, sin embargo, existe información limitada sobre su seguridad y sus resultados varían considerablemente. Nuestro objetivo es presentar la experiencia de nuestro centro en el tratamiento laparoscópico de la OIB. Material y Métodos: Estudio retrospectivo incluyendo pacientes con el diagnóstico de OIB que fueron sometidos a cirugía laparoscópica en nuestro centro, entre junio de 2003 y abril de 2013. Análisis de variables demográficas, quirúrgicas y resultados obtenidos en términos de tasa de conversión, tiempo operatorio, tiempo de realimentación y estadía hospitalaria. Análisis estadístico con pruebas no paramétricas. Resultados: Serie de 38 pacientes, edad promedio: 51 +/- 16 años, 47 por ciento sexo masculino. 53 por ciento con antecedente de cirugía abdominal previa. Resolución completa por laparoscopía fue posible en 31 pacientes (82 por ciento), con 7 conversiones a cirugía abierta. La mediana de tiempo operatorio fue de 60 m (25-180), la mediana de tiempo a la realimentación fue de 24 h (24-192) y la mediana de estadía hospitalaria de 4 (2-52) días. Dos pacientes requirieron reoperaciones durante su hospitalización; uno debido a obstrucción intestinal persistente y otro debido a colitis isquémica. No se presentaron otras complicaciones ni mortalidad en esta serie. Conclusiones: El abordaje laparoscópico en OIB es factible de realizar en pacientes seleccionados, logrando buenos resultados en caso de resolución completa por laparoscopía. Pacientes sin cirugías abdominales previas son buenos candidatos para un abordaje laparoscópico inicial.

Antecedentes: Existe una tendencia global creciente de no realizar laparoscopia diagnóstica en el estudio de pacientes con infertilidad inexplicada e histerosalpingografía normal. Este tipo de manejo podría tener ciertos inconvenientes dado que existen lesiones, especialmente tuboperitoneales, que no son diagnosticadas y pudiesen influir en los resultados. Nuestro grupo maneja estas pacientes con laparoscopia diagnóstica/terapéutica y posteriormente tres ciclos de inseminación intrauterina. Objetivos: Validar nuestro manejo de la infertilidad inexplicada, estimar la frecuencia de patología pélvica en pacientes con infertilidad inexplicada con histerosalpingografía normal, evaluar la tasa de embarazo posterior a la resolución laparoscópica de su patología y revisar la literatura existente. Resultados: Se revisaron todas las cirugías laparoscópicas realizadas en pacientes con infertilidad inexplicada del Hospital Clínico de la Universidad Católica, entre los años 2007-2011. De estas, 57 pacientes cumplían los criterios de inclusión y 39 recibieron al menos 1 ciclo de inseminación intrauterina posterior al procedimiento. El 82,4 por ciento de las pacientes presentaron hallazgos a la laparoscopia, siendo los más prevalentes la endometriosis grado I y II (57,8 por ciento), y las adherencias pelvianas (43,8 por ciento). De las 57 pacientes que fueron sometidas a laparoscopia diagnóstica/terapéutica, sólo 25 completaron 3 ciclos de inseminación intrauterina posterior, 8 lograron concepción (32 por ciento). Conclusión: Nuestros resultados son similares a los expuestos en otros trabajos en términos de hallazgos patológicos y tasa de fertilidad post laparoscopia. Dado el escaso acceso a técnicas de fertilización in vitro en nuestro medio, nuestro manejo plantea una excelente alternativa para este grupo de pacientes.
Background: There is an increased global tendency for avoiding a diagnostic laparoscopic surgery, among patients with unexplained infertility and a normal histerosalpingography. This decision may have certain consequences, as there may be undiagnosed lesions, such as tuboperitoneal ones, which could have an impact in the management of these patients. Our group treats them with diagnostic therapeutic laparoscopy, followed by three cycles of intrauterine insemination. Objectives: Validate our management of unexplained infertility, estimate the frequency of pelvic pathology in patients with unexplained infertility with a normal histerosalpingography, evaluate the pregnancy rate after the laparoscopic resolution of their pathology, and review the existent literature. Results: We reviewed all laparoscopic surgeries performed in patients with unexplained infertility in Hospital Clínico de la Pontificia Universidad Católica, between 2007-2011. From these, 57 patients met the inclusion criteria, and 39 of them received at least one intrauterine insemination cycle after the procedure. Laparoscopic alterations were present in 82.4 percent of the patients, being the most prevalent ones endometriosis grade I and II (57.8 percent) and pelvic adhesions (43.8 percent). Of the 57 patients who underwent laparoscopy, only 25 completed three cycles of intrauterine insemination, 8 of which conceived (32 percent). Conclusion: Our results are similar to those exposed in other series, regarding pathologic findings and fertility rate after laparoscopy. As there is limited access to advanced reproductive techniques in our country, our management represents an excellent choice for this group of patients.

OBJETIVO: Avaliar a prevalência de alterações anatômicas uterinas diagnosticadas através da histeroscopia ambulatorial em uma população de pacientes com mais de dois abortamentos consecutivos. Comparar a prevalência de alterações uterinas entre as pacientes com dois abortos em relação as pacientes com três ou mais abortamentos de repetição. MÉTODOS: Foi realizado um estudo transversal em 66 pacientes com diagnóstico de dois ou mais abortamentos de repetição. As pacientes foram divididas em dois grupos: Grupo A (até dois abortamentos, 23 pacientes) e Grupo B (três ou mais abortamentos, 43 pacientes), sendo submetidas à histeroscopia diagnóstica ambulatorial em que foram identificadas alterações congênitas e adquiridas da cavidade uterina. RESULTADOS: Foram encontradas em 22 (33,3 por cento) pacientes alterações uterinas, sendo em nove casos alterações congênitas [útero arqueado (quatro casos), septo uterino (dois casos) e útero bicorno (um caso)] e em 13 pacientes alterações adquiridas [sinéquia (sete casos), pólipo endometrial (quatro casos) e mioma uterino (dois casos). Não houve diferença significativa entre grupos em relação às alterações uterinas adquiridas e congênitas. Foi encontrada uma correlação positiva entre alterações anatômicas na histeroscopia e número de abortamentos (r = 0,31; p = 0,02). CONCLUSÃO: As pacientes com mais de dois abortamentos apresentam uma alta prevalência de alterações uterinas diagnosticadas por histeroscopia. No entanto não há diferença na prevalência ou na distribuição das lesões em relação ao número de abortamentos.
OBJECTIVE: To assess the prevalence of uterine anatomical abnormalities found by office diagnostic hysteroscopy in a population of patients experiencing more than two consecutive miscarriages and compare the prevalence of uterine abnormalities between patients with two miscarriages and those with three or more consecutive miscarriages. METHODS: A cross-sectional study of 66 patients with two or more consecutive miscarriages diagnosis was conducted. Patients were divided into two groups: Group A (up to two miscarriages, 23 patients), and Group B (3 miscarriages, 43 patients). They underwent an outpatient diagnostic hysteroscopy study, with either congenital or acquired abnormalities of the uterine cavity being identified. RESULTS: Uterine changes were found in 22 (33.3 percent) patients, with 9 cases of congenital changes [arcuate uterus (4 cases), septate uterus (2 cases), and bicornuate uterus (1 case)], and 13 patients with acquired changes [intrauterine adhesions (7 cases), endometrial polyp (4 cases), and uterine leiomyoma (2 cases)]. No significant differences were found between the groups as regarding both acquired and congenital uterine changes. A positive correlation was found between anatomical changes on hysteroscopy and number of miscarriages (r = 0.31; p = 0.02). CONCLUSION: Patients with more than two miscarriages have a high prevalence of uterine cavity abnormalities diagnosed by hysteroscopy; however there are no differences in prevalence or distribution of these lesions related to the number of recurrent miscarriages.
