Se realizó una revisión bibliográfica y se seleccionaron artículos en las fuentes electrónicas: Web of Science, Scielo, Elsevier, PubMed, Medline y Google, publicadas en la presente centuria en idiomas español e inglés. La apendicetomía mediante laparotomía ha sido siempre la regla de oro para el tratamiento de la apendicitis aguda. En 1982, se introdujo el acceso laparoscópico que ha demostrado ser tan seguro y eficiente como el convencional. En 2004, la cirugía endoscópica a través de orificios naturales; en 2007 por un solo puerto y en 2015 mediante endoscopia retrógrada. La evolución del cuadro clínico es variable por lo que se han propuesto estrategias como la cirugía ambulatoria, el tratamiento conservador seguido o no de cirugía de intervalo, a fin de evitar intervenciones innecesarias con morbilidad y mortalidad similares a las realizadas con urgencia. La apendicetomía mediante laparotomía o laparoscopia aun es la regla de oro del tratamiento de la apendicitis aguda, aunque se impone el acceso laparoscópico, han surgido nuevas técnicas invasivas y la cirugía ambulatoria. La antibioticoterapia es esencial y como tratamiento único tiene como objetivo disminuir los costos y la morbilidad asociada a la cirugía; por tanto, actualmente el tratamiento adecuado de esta enfermedad es controversial y dependerá de los protocolos de actuación establecidos, el estado del paciente y los recursos disponibles(AU)

ABSTRACT The objective of this work is to study in depth the different cognitive aspects about the new evidences concerning the treatment of acute appendicitis and to compare the results obtained with the different surgical techniques currently used and the conservative treatment. A bibliographic review was carried out and articles were chosen from the electronic sources Web of Science, Scielo, Elsevier, PubMed, Medline, and Google, published in this century in Spanish and in English. Appendectomy by laparotomy has always been the gold standard for the treatment of acute appendicitis. In 1982, laparoscopic access was introduced, which has proven safe and efficient as conventional access. In 2004, endoscopic surgery through natural orifices was used; in 2007, it was performed by a single port, and in 2015, through retrograde endoscopy. The evolution of the clinical picture is variable so strategies have been proposed such as ambulatory surgery, conservative treatment followed or not by interval surgery, in order to avoid unnecessary interventions with morbidity and mortality similar to those performed with urgency. Appendectomy by laparotomy or laparoscopy is still the golden standard of the treatment of acute appendicitis, although laparoscopic access is required, new invasive techniques and outpatient surgery have emerged. Antibiotic therapy is essential and, as a single treatment, aims to reduce costs and morbidity associated with surgery; therefore, the adequate treatment of this disease is currently controversial and will depend on the established protocols of action, patient condition, and the available resources(AU)

Two-Incision Laparoscopic Cholecystectomy: Reducing Scars in a Simple Way.

BACKGROUND: About 20% of the population has cholelithiasis and this is the main abdominal cause of hospitalization in developed countries. Considering that only in the United States about 700,000 cholecystectomies are done each year, it is possible to estimate the importance of the problem for public health. OBJECTIVE: To describe a two-incision laparoscopic cholecystectomy (TILC) technique using only conventional material, without increasing complications or operative time. MATERIALS AND METHODS: A consecutive and prospective case series compared to another historical operated by conventional laparoscopic cholecystectomy (LC). The TILC was performed with three trocars in two incisions, two trocars in umbilical incision, and one in epigastrium. RESULTS: A total of 72 patients were operated on by the same surgeon (36 in each group). There were no significant differences between groups for gender, mean age, body mass index, or length of hospital stay. The procedures were classified by the surgeon according to surgical difficulty and 58.3% (n = 42) were considered low grade, 9.7% (n = 7) difficult, and the other were intermediaries, with no difference between the series (P < .05). There were minor complications in 6.94% (n = 5) procedures. There were no differences between mean operative time (P = .989), which was 49 (95% confidence interval [CI] 42-56) minutes in LC and 40 (95% CI 35-44) min in TILC. There was no need for additional trocars in any case or for conversion to open surgery. CONCLUSIONS: TILC is feasible, safe, and with good aesthetic result, using the same instruments of LC, without increasing operative time.

Hernioplasta inguinal laparoscópica totalmente extraperitoneal por incisión única / Single - incision totally extraperitoneal inguinal hernia repair

Antecedentes: el tratamiento laparoscópico de la hernia inguinal ha ido ganando mayor aceptación en virtud de las ventajas del abordaje mininvasivo. Para mejorarlas más aún se plantea la incorporación de otras variantes técnicas. La hernioplasta inguinal totalmente extraperitoneal (TEP) por incisión única constituye una nueva opción, pero no existen en la actualidad series de casos que confirmen su factbilidad y seguridad. Objetivo: verificar la factbilidad y seguridad de dicho método en el tratamiento de la hernia inguinal reductble. Material y métodos: en pacientes sometidos a hernioplasta inguinal laparoscópica TEP por incisión única entre agosto de 2014 y agosto de 2015 se analizaron datos demográficos, tipo y tamaño de hernia, tipo y tamaño de la malla, número de agrafes, tempo operatorio, estadía hospitalaria y complicaciones. Se valoró la intensidad del dolor posoperatorio mediante una escala visual análoga, y grado de satisfacción. Se realizó ecografa de región periumbilical (sito de acceso) y de región inguinocrural tratada, con el objeto de evaluar el grado de morbilidad asociada y recidiva. Resultados: se realizaron 43 hernioplastas TEP por incisión única en 29 pacientes. En 14 pacientes fueron bilaterales (48,2%), 88,4% hombres, de edad promedio 40 años (16-72). Fueron hernias T2 e indirectas en el 72% de los casos. El tempo promedio de estadía fue de 0,56 días (0,5-1,5). La intensidad del dolor a las 12 horas y al 7° día posoperatorio, 4,1 puntos en promedio. El grado promedio de satisfacción con el resultado cosmético fue de 9,5 (rango 8-10). No se registraron complicaciones mayores y 4 casos (9,3%) presentaron complicación menor. El tempo quirúrgico promedio fue 38,3 minutos. No se detectó recidiva herniaria en toda la serie, con una media de seguimiento de 7,1 meses. Conclusiones: la hernioplasta inguinal TEP-incisión única consttuye una opción factble y segura de realizar en pacientes seleccionados con hernia inguinal pequeña y reductble, sin riesgo adicional y sin exigencia técnica adicional. Estos hallazgos se suman a los beneficios de un menor traumatismo de la pared abdominal y un mejor resultado cosmético.

Background: the laparoscopic treatment of inguinal hernia has gained greater acceptance, by virtue of the advantages already demonstrated by minimally invasive approach. For further improvement, the incor-poraton of new technical variantis arises. Extraperitoneal inguinal hernia repair by single incision is a new opton, not existing at present series of cases that confrm their feasibility and safety. Objective: to evaluate the feasibility and safety of this method in the treatment of reducible inguinal hernia. Materials and methods: in patentis undergoing inguinal hernia repair by single incision laparoscopic sur-gery - TEP between August 2014 and August 2015; demographics, type and size of hernia, type and size of mesh, number of staples, operative tme, hospital stay, and complicatons were analyzed. The intensity of postoperative pain using a visual analog scale, and degree of satisfacton was valued. Ultrasound of the periumbilical region (access site) and treated inguinocrural region, to assess the degree of associated mor-bidity and recurrence was performed. Resultis: forty three single-incision TEP hernia repairs were performed in 29 patentis. They were bilateral in 14 patentis (48.2%), 88.4% were men, with mean age 40 years (16-72). T2 and indirect hernias comprised 72% of cases. The average length of stay was 0.56 days (0.5-1.5). The average intensity of pain at 12 hours and the 7th postoperative day was 4.1 pointis (range 1 to 8). The average degree of satisfacton with the cosmetic result was 9.5 (range 8-10). No major complicatons were recorded, and 4 cases (9.3%) had minor complicaton. The average operative tme was 38.3 minutes. No hernia recurrence was detected throug-hout the series with a mean follow up of 7.12 months. Conclusions: inguinal hernia repair by totally extraperitoneal single incision is feasible and safe to perform in selected small and reducible inguinal hernia, without additonal risk and no technical burden. These fin-dings add to the beneftis of lower abdominal wall trauma and improved cosmetic result.

Laparoscopic single-incision gastric bypass: initial experience, technique and short-term outcomes.

BACKGROUND: Single incision laparoscopic surgery (SILS) research has been limited. The aim of this study is to describe our technique and to evaluate the short term outcomes and efficacy of SILS Roux-en-Y gastric bypass (RYGB) in a selected group of patients in a single center. METHODS: From March 2012 to January 2013, a total of fourteen patients underwent SILS RYGB using a single vertical 2.5-3 cm intra-umbilical incision, 3-ports placed trans-fascially, and a liver suspension technique in Cleveland Clinic's Bariatric & Metabolic Institute, in Cleveland, Ohio, USA. Patient selection, short-term outcomes and technical issues were retrospectively viewed in this study. RESULTS: A total of 14 morbid obese patients (12 women and 2 men; mean age, 46 years). Mean operative time was 196 (range 131-265) min. Mean weight at surgery was 113 (range 91-135) kg. One patient required placement of one additional port (7 %). No conversions to conventional laparoscopic surgery (CLS) or open surgery was needed. The estimated blood loss was 40 (range 20-100) ml. In terms of pain control, the frequency of patient controlled analgesia had a mean use of 21 times in postoperative day 0 (POD), 37 times in POD1 and 13 times in POD2. Pain score (assessed by visual analogue scale) had a median score of 6.9 in POD0, 5.2 In POD1 and 3.8 in POD2. Weight loss was approximately 7.25 lb. (±4.5) after first postoperative visit, 28.9 lb. (±11.86) after 1 month and 45.4 lb. (±15.4) after 4 months. No patients required re-operation or readmission during the 90 days after surgery. CONCLUSION: Single incision is feasible, safe and reproducible technique used as an access to complex surgeries like gastric bypass in carefully selected patients. Results in short-term outcomes are comparable to those observed in literature. Some potential benefits include less postoperative pain, improved cosmesis, and patient satisfaction. Randomized trials involving larger patient series with a longer follow-up and larger cohort studies and/or systematic reviews will be necessary to assess the extent of the benefits and limitations of SILS in bariatric surgery.

[Drainage of amoebic liver abscess by single incision laparoscopic surgery. Report of a case]. / Drenaje de absceso hepático amebiano por laparoscopia de puerto único. Reporte de un caso.

BACKGROUND: Single incision laparoscopic surgery has increased recently due to successful results, achieved in several procedures. The aim of the present work is to present the first case in which single incision laparoscopy is used for the drainage of an amoebic liver abscess. CLINICAL CASE: A 44-year-old man presented with intense right upper quadrant pain, generalised jaundice, tachycardia, fever, hepatomegaly and a positive Murphy's sign. Laboratory results revealed an increased plasma bilirubin, elevated alkaline phosphatase and transaminases, leucocytosis, negative viral panel for hepatitis, and positive antibodies against Entamoeba histolytica. On an abdominal computed tomography a 15 × 12.1 cm hypodense lesion was observed in the patient's liver, identified as an amoebic liver abscess. Analgesics and antibiotics were started and subsequently the patient was submitted to laparoscopic drainage of the abscess using a single port approach. Drainage and irrigation of the abscess was performed. Four days later the patient was discharged without complications. CONCLUSION: Management of amoebic liver abscess is focused on the elimination of the infectious agent and obliteration of the abscess cavity in order to prevent its complications, especially rupture. Laparoscopic surgery has proved to be a safe and effective way to manage this entity.

Single-incision laparoscopic sleeve gastrectomy: initial experience in 20 patients and 2-year follow-up.

BACKGROUND: The transumbilical route began being clinically feasible with or without unique access devices. SETTING: The setting for this study was a private practice at Clínica Las Condes, Santiago, Chile. OBJECTIVE: The objective was to describe our experience performing a laparoscopic sleeve gastrectomy (LSG) via transumbilical route using a single-port access device in addition to standard laparoscopic instruments. METHOD: A prospective nonrandomized protocol was applied to patients fulfilling the following inclusion criteria: to have been medically indicated for an LSG, to have a body mass index (BMI) of less than or equal to 40 kg/m2, and the distance between the xiphoid appendix and umbilicus should be less than 22 cm. All patients were female with a median (p50) age of 34.5 (ranging from 21 to 57) years, a median weight of 92 (ranging from 82.5 to 113) kg, and a median BMI of 35.1 (ranging from 30.5 to 40) kg/m2. The device insertion technique, the gastrectomy, and postoperative management are described. RESULTS: LSG via transumbilical route was successfully carried out in 19 of the 20 patients in whom the procedure was performed; one patient had to be converted to a conventional laparoscopic procedure. Mean operating time was 127 (ranging from 90 to 170) min. On the second postoperative day, all patients were assessed through an upper gastrointestinal barium-contrasted radiological series. There was neither morbidity nor mortality in this group. Excess weight loss at 25 months after surgery was 114 %. CONCLUSIONS: Single-port LSG can be successfully performed in selected obese patients with a BMI of less than 40 kg/m2 using traditional laparoscopic instruments. The technique allows performing a safe and effective vertical gastrectomy.

Cirugía endoscópica por monopuerto: reporte de nuestra experiencia en los primeros 175 casos por sils port en Venezuela / Endoscopic surgery by singleport: report of our experience in the first 175 cases by sils port in Venezuela

El último paso hacia el menor grado de invasión después del surgimiento de la cirugía laparoscópica ocurre cuando los cirujanos del mundo se inician en técnicas emergentes, que entre otras, utilizan el ombligo como único puerto de entrada al abdomen quedando camufladas en la cicatriz umbilical, Presentamos la experiencia inicial de nuestro grupo, entre julio de 2009 hasta enero 2011 en variados procedimientos laparoscópicos por monopuerto con el uso del dispositivo SILS® port. Fueron intervenidos 175 pacientes, 163 adultos (93%), 12 niños (7%), todos abordados por un sólo puerto y a través del SILS® port. Se realizaron 102 colecistectomías (58%), 37 apendicectomías (21%), 8 histerectomías (4,6%), 7 ooforectomías (4%), 7 biopsias hepáticas (4%), 6 liberación de bridas y adherencias (3,4%), 4 salpingoclasias (2,3%), 2 esplenectomías (1%), 1 miotomía de Heller con funduplicatura de Dor (0,6%) 1 hiatoplasia esofágica (0.6%). Los procedimientos complejos se efectuaron después de realizados los primeros 50 casos. Todos los procedimientos en niños se completaron por incisión única de manera satisfactoria. En los adultos, 6 requirieron un puerto un adicional, en un paciente fue necesario dos puertos con posterior conversión a laparotomía (hiatoplastia esofágica). Los tiempos promedios resultaron para colecistectomías 42 min (12-72 min), apendicectomía 37,5 min (13-62 min), histerectomías 95 min (65-125 min), ooforectomías 32,5 min (15-50 min), salpingoclasia 18,5 min (12-25 min), miotomía de Heller 182 min, hiatoplastia esofágica 155 min. La cirugía laparoscópica por incisión única es una técnica emergente en franco desarrollo, en niños ha demostrado ser un procedimiento seguro y eficaz, al igual que en adultos. El desarrollo y perfeccionamiento del instrumento hará ampliar el horizonte y abarcar cirugía más complejas y considerarse como alternativa a la cirugía laparoscópica tradicional otorgando el beneficio de menos dolor y mejores resultados estéticos...

We present the initial experience of our work group, between July 2009 and January 2011 in several laparoscopic procedures by monoport with device SILS port. Patients and method: 175 patients underwent surgery, 163 adults (93%), 12 children (7%), all boarded through a single port with SILS port device, 102 cholecystectomies were made (58%), 37 appendectomies (21%) 8 hysterectomies (4.6%), 7 oophorectomies (4%). 7 hepatic biopsies (4%), 6 liberation of bridles and adhesions (3,4%), 4 segmental resection of fallopian tube (2.3%), 2 splenectomies (1%), 1 Heller miotomy with Dor funduplication (0.6%) and 1 hiatal repair (0.6%). The complex procedures were carried out alter made the first 50 cases. All the procedures in children were completed through unique incision. In the adults. 6 required an additional port; in a patient was necessary two port with later conversion to laparotomy (hiatal hernia repair). The operative times averages were for cholecystectomies 42 min (12-72 min), Appendectomies 37,5 min. (13-62 min). Hysterectomies 95 min (65-125 min), Oophorectomies 32.5 min (15-50 min), segmental resection of fallopian tube 18.5 min (12-25 min), Heller miotomy 182 min. Hiatal hernia repair 155 min. The laparoscopic surgery through unique incision is an emergent technique in frank development, in children has demonstrated to be a safe and effective procedure, like in adults. The development and improvement of instruments will make extend the horizon and include more complex surgeries and consider themselves like alternative to the traditional laparoscopic surgery, granting the benefit of less pain and better aesthetic results. The development of skills and abilities to move in a NEW ATMOSPHERE represent a main concern.

Gastrectomía vertical laparoscópica transumbilical / Transumbilical sleeve gastrectomy: experience in six patients

Background: The transumbilical route can be used to perform sleeve gastrectomies. Aim: To report the experience with transumbilical sleeve gastrectomy. Material and Methods: A prospective protocol of transumbilical sleeve gastrectomy was applied among patients with a body mass index of 36 kg/m² or less, and a distance between the xiphoid process and the umbilicus of less than 22 cm. Results: Six female patients, with a body mass index between 32.5 and 35.3 kg/m² have been operated. The operative time ranged from 90 to 170 min. An additional 5 mm trochar was required in the first two patients. The postoperative barium swallow showed a good distal passage and the absence of stenosis, residual fundus or nitrations in all patients. No patient had complications. Conclusions: Transumbilical sleeve gastrectomy is feasible among patients with a body mass index of less than 36 kg/m².

Introducción: La cirugía laparoscópica ha estado orientada los últimos años a buscar otras alternativas mínimamente invasivas de acceso abdominal. La transumbilical es una vía que ha comenzado a ser aplicada clínicamente, con o sin dispositivos de acceso único. Hemos comenzado a realizar la gastrectomía vertical laparoscópica (GVL) por vía transumbilical, en ciertos casos seleccionados. Objetivo: Evaluar la factibilidad de realizar la GVL por vía transumbilical, utilizando un dispositivo de acceso único y el resto del instrumental laparoscópico tradicional. Método: Protocolo prospectivo aplicado a pacientes que cumplan con criterios de inclusión como: ser candidato a GVL, tener IMC igual o menor a 36 kg/m², distancia entre apéndice xifoides y ombligo menor a 22 cm. El peso promedio de las pacientes operadas fue de 90,5 kg, (82,5-98), IMC promedio de 33,8 kg/m² (32,5-35,3). Se describe la técnica de inserción del dispositivo, de la gastrectomía y del manejo postoperatorio. Resultados: Se logró realizar GVL en las 6 pacientes en las que se intentó. El tiempo operatorio promedio fue de 127 min (90 a 170 min), en las dos primeras pacientes se requirió el uso de un trocar adicional de 5 mm. En todas las pacientes, la radiografía baritada de esófago, estómago y duodeno mostró buen paso a distal y ausencia de estenosis, fondo residual o filtraciones. No hubo morbilidad en este grupo. Conclusiones: La GVL es factible de realizar en pacientes portadores de obesidad menor a 36 kg/ m²de superficie corporal, usando un dispositivo de acceso único e instrumental laparoscópico tradicional.
