Factores predictivos de infección de herida en cirugía colorrectal. Estudio observacional multicéntrico de casos y controles

Introduction

The aim of this study is to evaluate the usefulness of Vicryl Plus^® suture in reducing the rate of postoperative wound infection in elective colorectal surgery.

Methods

A prospective case-control multicenter study with 480 patients undergoing elective colorectal surgery was performed between 2006 and 2007. Patients were divided in 2 groups of equal sample size: group 1, closure of the abdominal wall using Vicryl Plus^® and group 2 where PDS II^® was used. The study involved 5 hospitals in the Spanish State. Wound infection was classified into superficial and deep. All patients diagnosed of wound infection during the hospital stay and up to 30 days after discharge were studied. For the statistical analysis Chi-square test and Fisher exact were used for bivariate analysis and logistic regression model for multivariate analysis.

Results

Wound infection rates were significantly lower in group 1: 14.6 vs. 29.2. Multivariate analysis showed that risk of wound infection was higher in patients with cancer, lung disease, anemia, operative time greater than 2 h, lack of second dose intra-operative prophylactic antibiotic and laparotomy closure with PDS suture II^®.

Conclusions

The use of suture coated with triclosan can be an effective prophylactic tool in reducing wound infection rate in patients undergoing elective colorectal surgery.     

Implicaciones pronósticas del estudio estandarizado de los márgenes de resección en el cáncer de páncreas

Introduction

Involvement of surgical resection margins is a fundamental prognostic factor in pancreatic oncological surgery. However, there is a lack of standardized histopathology definition. The aims of this study are to investigate the real rate of R1 resections when surgical specimens are evaluated according to a standardized protocol and to study its survival implications.

Patients y methods

One hundred consecutive surgically resected patients with pancreatic ductal adenocarcinoma were included in the study. They were further divided in 2 groups: pre-protocol, evaluated before the introduction of the standardized protocol and post-protocol, analyzed with the standardized protocol.

Results

R0 resection rate in the pre-protocol group was 78%, falling to 47% after the introduction of the standardized protocol (p = 0,003). The posterior retroperitoneal margin was the most frequently involved margin. In cases with tumors located at the pancreatic head and analyzed according to the standardized protocol R1 involvement negatively affected survival. Median survival in the R0 group was 22 months versus 16 in those with the margin involved (HR: 2.044; IC 95% 1,00-4,16; P=.043).

Conclusions

Standardized evaluation of the retroperitoneal margins in pancreatic cancer increases the rate of R1 patients. In cases with pancreatic cancer located at the pancreatic head involvement of posterior retroperitoneal margin significantly decreases survival.     

Resultados de la rehabilitación pelviperineal en pacientes con disinergia del suelo pélvico

Introduction

Pelvic floor dyssynergia (PPD) is a common cause of outlet obstruction constipation. Treatment for this condition is based on pelvi-perineal re-education (PPR). The aim of this study was to evaluate the results of PPR on patients with PPD

Methods

Patients with the diagnosis of PPD were included. The study was conducted between 2010 and 2011. PPR was performed by specialized kinesiologists. Prior and after treatment a constipation questionnaire was performed (KESS) (scale from 0 to 39 points, a higher score is associated with more symptom severity). KESS score before and after PPR were compared. Mann-Whitney-Wilcoxon rank sum test for paired samples was used for statistical analysis, p value <0,05 was considered as significant.

Results

Thirteen patients were included (11 women), mean age 44.3 years old (r: 18-76). Mean total KESS score prior and after PPR were 19.6 (SD: 5.8) and 12.6 (DS: 63), respectively (P=.002).Frequency of bowel movements, stool consistency, abdominal pain and abdominal bloating did not present statistically significant changes before and after treatment. Use of laxatives, enemas and/or digitations, as well as unsuccessful evacuation, feelings of incomplete evacuation improved significantly. Total evacuation time (before 1.53 vs after 1; P= .012) and difficult evacuation causing painful efforts (before 2.08 vs after 1.07; P=.001) also decreased significantly.

Conclusion

PPR in patients with PPD, significantly improves the symptoms of obstructive constipation, mainly with respect to mechanical assistance and difficult evacuation.     

Nuevo método de operar en la eventración compleja: separación anatómica de componentes con prótesis y nuevas inserciones musculares

Introduction

Our goal is to show the surgical community a new technique developed by our team for treating complex and catastrophic ventral hernias: Separation of Anatomical Component (SAC) amended by Carbonell-Bonafé.

Materials and methods

A total of 100 patients with complex incisional hernias have been treated. The size, content and reducibility of ventral hernia (preoperative CT scan), recurrences and pre-closure techniques, height and weight, trophic skin alterations and need for preoperative pneumoperitoneum were all documented. The operation was performed following a standardised protocol; intra-abdominal pressure (IAP) was measured before, during and after the intervention. Patients were evaluated in the clinic at 15 and 30 days, monthly for 3 months, at sixth months and annually for up to 5 years.

Results

A total of 100 consecutive patients were operated on between January 2003 and May 2008. In the immediate post-surgical period there were 12% seromas, 8% of partial-ischaemia on the edges of the wound and 1 death due to multi-organ failure. In the later period, 6% had transitional pain in bone anchorage points. They resumed their normal activities after an average of 2 months, with great improvement in their quality of life. There have been no recurrences to date.

Conclusions

The SAC technique, as modified by our Unit, is an excellent resource in managing large ventral hernias: successfully closing with low morbidity, as well as reconstructing the biomechanics of the abdominal wall.     

Infección de la prótesis en la reparación herniaria. Nuestra experiencia en 5 años

Introduction

Prosthesis infection is an infrequent but important complication in abdominal wall surgery. The aim of this study is to evaluate the incidence and risk factors for the infection of the prosthesis after hernia repair, as well as the treatment to apply.

Material and method

Between January 2002 and December 2006, we performed 1055 prosthetic hernia repairs: 761 inguinal hernias (72.1%), 74 umbilical hernias (7%) and 220 ventral hernias (20.9%). We prospectively analysed preoperative, intraoperative and postoperative variables, as well as the incidence of infection of surgical wound and of prosthesis. We used ASA classification for preoperative anaesthetic evaluation.

Results

The overall percentage of infection of the prosthesis was 1.3%. Infection was observed in 11 repairs with polypropylene mesh (PPL), in 4 with PTFE mesh, and one case in combined mesh. Risk factors of mesh infection were: obesity (p=0.002), diabetes (p=0.020), the type of repair (p=0.047), emergency surgery (p=0.001), the type and size of mesh (p=0.003; p=0.007) and time of surgery >180 min (p<0.001). Seven of the 11 patients with infection of PPL prosthesis were resolved with conservative treatment, whereas all the cases with PTFE infection or mixed mesh needed removal to solve the problem.

Conclusions

Several factors are involved in producing a prosthesis infection. Whereas antibiotic treatment and surgical drainage of the infection can be sufficient in most PPL mesh infection, PTFE prostheses need to be removed prematurely in order to halt the infection process.     

Vólvulo de ciego: presentación de 18 casos y revisión de la literatura

Introduction

Caecal volvulus is the second most frequent location of colonic volvulus after sigmoid colon. It usually shows up as bowel obstruction.

Material y method

We review our experience of 18 cases of cecal volvulus treated in our centre between 1987 and 2007.

Results

We studied 8 males (44.4%) and 10 females (55.6%), with a mean age of 63.3 years. As an associated factor it was noted that 10 patients (55.6%) were bedridden. The most common clinical signs were abdominal distensión and tenderness, constipation and vomiting. Simple abdominal X-rays have a low diagnostic accuracy, though they reveal a bowel obstruction. Only 1 patient underwent elective surgery. In 10 patients (55.6%) a right hemicolectomy was performed, in 3 (16.8%) cecostomy, in 3 cecopexy and in 2 (11.2%) devolvulation only. There were complications in 3 patients (16.8%), 2 prolonged ileus and 1 wound infection. There were no recurrences.

Conclusions

Caecal volvulus is an emergency pathology, requiring surgical treatment. Right hemicolectomy is the treatment of choice both in viable and gangrenous colon. Caecostomy is an alternative treatment in the high risk patient with a viable colon.     

Influencia de la presión atmosférica sobre la incidencia de neumotórax espontáneo

Background

This study analyses the relationship between the incidence of idiopathic spontaneous pneumothorax (ISP) and atmospheric pressure (AP).

Methods

A total of 288 cases of ISP were included, 229 men and 59 women. The AP of the day of diagnosis, of the 3 prior days and the monthly average was registered. The association between the incidence of ISP and AP was analyzed by calculating standardized incidence ratio (SIR) and Poisson regression.

Results

The AP on the day of admission (mean ± standard deviation) (1,017.9 ± 7 hectopascals [hPa]) was higher than the monthly average AP (1,016.9 ± 4.1 hPa) (P =.005). There was a monthly distribution pattern of ISP with the highest incidence in the months of January, February and September and the lowest in April. When AP was less than 1,014 hPa, there were fewer cases registered than what would statistically have been expected (58/72 cases). In contrast, when the pressure was higher than 1,019 hPa, the registered cases were more than expected (109/82 cases) (SIR = 1.25; 95% CI: 1.04 to 1.51). The risk of ISP increased 1.15 times (95% CI: 1.05 to 1.25, P =.001) for each hPa of AP, regardless of sex, age and monthly average AP. A dose-response relationship was observed, with progressive increases in risk (IRR = 1.06 when the AP was 1,014-1016 hPa; 1.17 hPa when the AP was 1,016-1,019 hPa and 1.69 when AP was superior to 1,019 hPa) (P for trend =.089).

Conclusion

The AP is a risk factor for the onset of idiopathic spontaneous pneumothorax.     

Utilidad de un sistema de seguimiento óptico de instrumental en cirugía laparoscópica para evaluación de destrezas motoras

Introduction

The objective of this study is to assess the usefulness of an evaluation system of surgical skills based on motion analysis of laparoscopic instruments.

Method

This system consists of a physical laparoscopic simulator and a tracking and assessment system of technical skills in laparoscopy. Six surgeons with intermediate experience (between 1 and 50 laparoscopic surgeries) and 5 experienced surgeons (more than 50 laparoscopic surgeries) took part in this study. All participants were right-handed. The subjects performed 3 repetitions of a cutting task on synthetic tissue with the right hand, dissection of a gastric serous layer, and a suturing task in the dissection previously done. Objective metrics such as time, path length, speed of movements, acceleration and motion smoothness were analyzed for the instruments of each hand.

Results

In the cutting task, experienced surgeons show less acceleration (P=.014) and a smoother motion (P=.023) using the scissors. Regarding the dissection activity, experienced surgeons need less time (P=.006) and less length with both instruments (P=.006 for dissector and P=.01 for scissors). In the suturing task, experienced surgeons require less time (P=.037) and distance travelled (P=.041) by the dissector.

Conclusions

This study shows the usefulness of the evaluation system for the cutting, dissecting, and suturing tasks. It represents a significant step in the development of advanced systems for training and assessment of surgical skills in laparoscopic surgery.     

Estudio de coste-beneficio comparando la reparación de la hernia ventral abierta y laparoscópica

Objective

Laparoscopic surgery is a successful treatment option offering significant advantages to patients compared with open ventral hernia repair. A cost-benefit analysis was performed to compare the clinical results and economic costs of the open and laparoscopic techniques for anterior abdominal wall hernia repair, in order to determine the more efficient procedure.

Material and methods

We performed a prospective study of 140 patients with primary and incisional hernia, and analyzed clinical data, morbidity, costs of surgery and hospital stay costs.

Results

The cost of disposable surgical supplies was higher with laparoscopic repair but reduced the average length of stay (P < .001) and patient morbidity (P < .001). The total cost of the laparoscopic procedure was, therefore, less than initially estimated, yielding a savings of 1,260 € per patient (2,865 € vs. 4,125 €).

Conclusions

Laparoscopic ventral hernia repair is associated with a reduced complication rate, a lower average length of stay and with lower total costs. Laparoscopic repair can save 1.260 € for each patient, and so this procedure should be considered a cost-effective approach.     

Estudio prospectivo controlado y aleatorizado sobre la necesidad de la preparación mecánica de colon en la cirugía programada colorrectal

Introduction

Mechanical preparation of the colon (MPC) in colorectal surgery has been a dogma that has been questioned over the last few years. The objective of this study is to demonstrate that morbidity in scheduled colorectal surgery is the same or lower without MPC.

Material and method

Patients subjected to scheduled left colon and rectal surgery with primary anastomosis randomised into two groups. The “Preparation” group (MPC) received MPC and the “non-preparation” group (No-MPC) had only cleaning enemas. The variables collected were: demographic, oncological, nutritional, risk prediction models and morbidity-mortality.

Results

Of the 193 patients included: 69 received MPC and 71 did not; 89 patients with colocolic anastomosis (MPC, 38; no MPC, 51) and 50 colorectal (MPC, 31; no MPC, 19). Statistically significant differences were seen in the overall analysis in favour of “no preparation” as regards morbidity (43.55 % with MPC and 27% with No MPC) and nosocomial infection (27.5% and 11.4%). There was 11.6% wound infections in the MPC compared to 5.7% in the no MPC, which was not statistically significant. The only mortalities were in the MPC group 2/69 (2.9% of patients). As regards the location of the anastomosis, in the colocolics the differences were more pronounced, with statistically significant differences in the morbidity, anastomosis dehiscence, and nosocomial infection variables. The effect of no MPC was not so evident in colorectal anastomosis.

Conclusions

Our results suggest that there is no benefit in MPC before surgery in colocolic anastomosis. No-MPC is not associated with a higher morbidity in wound infection or anastomotic dehiscence. In colorectal anastomosis the differences are not so evident, therefore a much bigger series needs to be studied.     

Descripción de los hallazgos de la ecografía endoanal en pacientes con incontinencia fecal mediante un sistema de puntuación

Introduction

The main aim of the study was to apply a severity classification of sphincter lesions detected by endoanal ultrasound using Starck score in patients who suffered faecal incontinence.

Material and method

Data were analysed on 133 patients with faecal incontinence. Those in whom anal sphincter lesions were detected by endoanal ultrasound are described and their corresponding scores according to Starck classification calculated. This system scores severity of detected sphincter lesions from 0 to 16, involving the three axes of the anal canal. Patient demographic characteristics and anorectal manometry results were also analysed. The relationship between this score, patient gender and age, and anorectal manometric results were also analysed.

Results

A total of 83 (62.4%) patients had some type of anal sphincter lesion. The presence of sphincter defects was not related to gender (P=0.172), although it did correlate with younger ages (P=0.028). The severity of anal sphincter damage by Starck score did not show significant correlation to gender (P=0.327) or to the age (P=0.350) of patients. However, a significant correlation was detected between Starck score and anal resting pressure (P=0.008) or anorectal squeeze pressure (P=0.011).

Conclusions

The presence of anal sphincter injuries could be well defined by Starck score in patients with faecal incontinence. Severity of damage scored by Starck correlated with anorectal manometric results.     

Prevalencia y características clínicas de la enfermedad venosa crónica en pacientes atendidos en Atención Primaria en España: resultados del estudio internacional Vein Consult Program

Introduction

The aim of this study was to evaluate the prevalence, clinical characteristics and management of chronic venous disease (CVD) in patients seen at primary care clinics

Patients and methods

This cross-sectional study was carried-out in Spain by 999 primary care physicians. They recruited 20 consecutive patients who were attending their clinics for any reason except for a medical emergency. The following Information was collected: demographic data, CVD risk factors, physical examination, clinical characteristics of the CVD and how it was managed.

Results

19,800 patients were included, predominantly women (63%), with a mean age of 53.7 ± 20 years. The prevalence of CVD (CEAP categories C1 to C6) was 48.5% (95% CI, 47.8 to 49.2), significantly higher in women (58.5%; 95% CI, 57.6 to 59.4) than in men (32.1%; 95% CI, 31.0 to 33.1). The greater the age the higher the prevalence and the more advanced the CVD. Ninety-nine percent of the patients required some form of treatment, with a greater proportion among women (72% vs. 39%, P<.0001). Sclerotherapy, endothermal ablation or surgery was required by 4% of the patients. Referral to the specialist was considered for 7% of the patients.

Conclusion

Chronic venous disease is highly prevalent among patients seen at primary care clinics in Spain, especially in women and elderly patients. Referral to a specialist and/or the use of the more invasive treatment procedures is uncommon.     

Periodo prequirúrgico y duración de la incapacidad temporal por contingencias comunes en la hernia inguinal

Background and objective

To analyze non-work-related sickness absence (NWR-SA) due to inguinal hernia and the factors related to its duration, paying particular attention to the pre-surgical period of NWR-SA.

Material and methods

Prospective cohort study was conducted on 1,003 workers with an episode of NWR-SA due to an inguinal hernia, belonging to the insured population of a mutual insurance company. We assessed the duration of the NWR-SA episodes and the main demographic, occupational and clinical variables potentially related to it. Cox regression analyses were conducted to establish the predictors of NWR-SA duration.

Results

The mean duration of NWR-SA due to inguinal hernia was 68.6 days. After multivariate analysis (Cox regression), having a pre-surgical period of NWR-SA (HR = 0.35; 95%CI: 0.28-0.43), manual occupations (HR=0.68; 95%CI: 0.49-0.95), construction sector (HR=0.71; 95%CI: 0.58-0.88), direct payment methods by a Mutual Insurance Company during sick leave in self-employed workers (HR=0.58; 95%CI, 0.41-0.82), or employees (HR=0.51; 95%CI: 0.36-0.72), comorbidity (HR=0.45; 95%CI:0.34-0.59), and surgery performed under an entity other than the Public Health System or a mutual insurance company (HR=0,76; 95%CI: 0.59-0.97) were associated with longer NWR-SA. The Mutual Insurance Company always performed the surgery when a pre-surgery period of NWR-SA existed (mean duration=47 ±39.6 days); that was associated with shorter periods of post-surgical NWR-SA (P=.001).

Conclusions

The NWR-SA due to inguinal hernia is a multifactorial phenomenon in which the pre-surgery period plays an important role. The collaboration between organizations involved in the management of NWR-SA seems to be an effective strategy for reducing its duration.     

Elegir a la cirugía como especialidad: Opiniones de los estudiantes de la Universidad de Buenos Aires sobre la cirugía y los cirujanos

Introduction

Since the number of applicants to residencies in general surgery in Argentina seems to be decreasing, we designed this work with the objective of studying the factors considered undesirable by students when choosing surgery as a specialty.

Material and methods

Between March and April 2012, one-hundred students were surveyed with a structured questionnaire with true/false binary answers in an observational case-control design. The survey contained 26 statements that made reference to characteristics of surgery as a specialty, or about the personality and lifestyle of surgeons, as they could be perceived by students. As a control group the same survey was applied to 20 surgeons who were in contact with the students and that could represent a role model for them during their rotation in surgery.

Results

Comparison between students and surgeons showed no difference in most answers, except in «surgery has poor reimbursement» (OR: 8,9; P=.0001), «there is not enough job demand» (OR: 8,1; P=.015), «surgery restrains intellectual development» (OR: 17,5; P=.014), «surgeons have too many non-scheduled activities» (OR: 9,36; P=.024), «they have a limited patient-physician relationship» (OR: 3,61; P=.009), «they have little time for family» (OR: 4,27; P=.036) and «they are exposed to infectious diseases» (OR: 5,90; P=.007).

Conclusions

Women would be as interested as men in working as surgeons; a remarkable fact when considering that the surgical specialties have been predominantly filled by men. The fact that surgeons mostly coincide with the views of students means that role models should be reviewed to promote vocations.     

Efecto de la simulación quirúrgica en la implementación clínica de procedimientos colorrectales laparoscópicos

Introduction

Advanced laparoscopic surgery requires supplementary training outside the operating room. Clinical simulation with animal models or cadavers facilitates this learning.

Objective

We measured the impact on clinical practice of a laparoscopic colorectal resection training program based on surgical simulation.

Material and methods

Between March 2007 and March 2012, 163 surgeons participated in 30 courses that lasted 4 days, of 35 hours (18 h in the operating room, 12 h in animal models, and 4 h in seminars). In May 2012, participants were asked via an on-line survey about the degree of implementation of the techniques in their day-to-day work.

Results

Seventy surgeons (47%) from 60 different hospitals answered the survey. Average time elapsed after the course was 11.5 months (2-60 months). A total of 75% initiated or increased the number of surgeries performed after the training. The increase in practice was > 10 cases/month in 19%, and < 5 cases/month in 56% of surgeons. 38% of participants initiated this surgical approach.

Conclusions

Seventy five percent of the surveyed surgeons increased the clinical implementation of a complicated surgical technique, such as laparoscopic colorectal surgery, after attending a training course based on clinical simulation.     

Calidad de la información en el proceso del consentimiento informado para anestesia

Objectives

To assess the quality of the information that patients receive in the informed consent document signed prior to surgery.

Material and methods

Cross-sectional study of a sample of cancer patients admitted for surgery at the University Hospital San Cecilio of Granada in 2011. After checking the inclusion criteria and obtaining their consent, demographic data were collected and procedure data, and a questionnaire «ad hoc» to assess the quality and comprehensiveness of the information provided in the informed consent.

Results

150 patients were studied. The majority (109 over 150) said they had received sufficient information, in appropriate language, and had the opportunity to ask questions, but only 44.7% correctly answered three or more issues related to anesthesia. University education level, knowledge of the intervention, information about the anesthesia problems and appropriate language were associated.

Conclusions

Although systematic informed consent was performed, half of the patients did not comprehend the anesthesia risks. Variables primarily related to the information received were associated with the quality of the response, but not with patient characteristics.     

Facteurs prédictifs de dysfonction rénale postopératoire après arthroplasties totales de hanche

Introduction

Postoperative renal dysfunction (PRD) is well-documented after cardiovascular surgery but there are only limited available data concerning major orthopedic surgery, although patients may have several risk factors prone to impair renal function. We designed an epidemiologic prospective study to assess the incidence of PRD after total hip arthroplasty (THA) and to determine risk factors.

Patients and methods

Were included in the study 755 patients scheduled for THA in a single centre, over a 14 months period. Thirty-one demographic, clinical and biological parameters were collected for each patient. PRD was defined by a value of glomerular filtration, determined by the Cockroft and Gault formula ≤ 60 ml/min per 1.73 m², on the seventh postoperative day. Risk factors were determined by univariate and then multivariate analyses using a linear regression model.

Results

Pre- and postoperatively (POD7), respectively 22.4% and 31.4% of the patients, had a creatinine clearance less than 60 ml/min per 1.73 m². Univariate analysis documented age, ASA score, diabetes mellitus, chronic hypertension, the use of diuretics and NSAID, anemia, and an increased value of plasma urea as risk factors. Risk factors documented by multivariate analysis were: preoperative creatinine clearance less than 60 ml/min per 1.73 m², (OR: 5.8, 95% confidence interval: [1.6–8.1], p = 0.0006), preoperative plasma urea greater than 7.49 mmol/l (2.1 [1.4–11.1], p = 0.04), age above 70 years (1.8 [1.1–4.3], p = 0.02), and duration of NSAID's treatment beyond 5 days (3.2 [1.4–7.1], p = 0.02).

Conclusion

PRD is common after THA and is prone to develop in aged patients with comorbidities. Duration of NSAID's administration should be limited in those patients.     

Utilidad de la escala Obesity surgery mortality risk score en la predicción de complicaciones tras cirugía bariátrica por vía laparoscópica

Introduction

Morbimortality after bariatric surgery varies according to patient characteristics and associated comorbidities. The aim of this study was to evaluate the usefulness of the Obesity sugery mortality risk score scale (OS-MRS) to predict the risk of postoperative complications after bariatric surgery.

Methods

A retrospective study was performed of a prospective series of patients undergoing bariatric surgery in which the OS-MRS scale was applied preoperatively. Postoperative complications were classified as proposed by Dindo-Clavien. We analyzed the relationship between the categories of OS-MRS scale: A) low risk, B) intermediate risk, and C) high risk and the presence of complications.

Results

Between May 2008 and June 2012, 198 patients were included (85 [42.9%] after gastric bypass and 113 [57.1%] after sleeve gastrectomy). Using the OS-MRS scale, 124 patients were classified as class A (62.6%), 70 as class B (35.4%) and 4 as class C (2%). The overall morbidity rate was 12.6% (25 patients). A significant association between OS-MRS scale and rate of complications (7.3, 20 and 50%, respectively, P=.004) was demonstrated. The gastric bypass was associated with a higher complication rate than sleeve gastrectomy (P=.007). In multivariate analysis, OS-MRS scale and surgical technique were the only significant predictive factors.

Conclusions

The OS-MRS scale is a useful tool to predict the risk of complications and can be used as a guide when choosing the type of bariatric surgery.     

25 años de cirugía laparoscópica en España

Introduction

The introduction of laparoscopic surgery (LS) can be considered the most important advancement in our specialty in the past 25 years. Despite its advantages, implementation and consolidation has not been homogenous, especially for advanced techniques. The aim of this study was to analyse the level of development and use of laparoscopic surgery in Spain at the present time and its evolution in recent years.

Material and methods

During the second half of 2012 a survey was developed to evaluate different aspects of the implementation and development of LS in our country. The survey was performed using an electronic questionnaire.

Results

The global response rate was 16% and 103 heads of Department answered the survey. A total of 92% worked in the public system. A total of 99% perform basic laparoscopic surgery and 85,2% advanced LS. Most of the responders (79%) consider that the instruments they have available for LS are adequate and 71% consider that LS is in the right stage of development in their environment.

Conclusions

Basic laparoscopic surgery has developed in our country to be considered the standard performed by most surgeons, and forms part of the basic surgical training of residents. With regards to advanced LS, although it is frequently used, there are still remaining areas of deficit, and therefore, opportunities for improvement.     

Impacto de un programa de rehabilitación multimodal en cirugía electiva colorrectal sobre los costes hospitalarios

Introduction

Multimodal rehabilitation (MMRH) programs in surgery have proven to be beneficial in functional recovery of patients. The aim of this study is to evaluate the impact of a MMRH program on hospital costs.

Method

A comparative study of 2 consecutive cohorts of patients undergoing elective colorectal surgery has been designed. In the first cohort, we analyzed 134 patients that received conventional perioperative care (control group). The second cohort included 231 patients treated with a multimodal rehabilitation protocol (fast-track group). Compliance with the protocol and functional recovery after fast-track surgery were analyzed. We compared postoperative complications, length of stay and readmission rates in both groups. The cost analysis was performed according to the system «full-costing».

Results

There were no differences in clinical features, type of surgical excision and surgical approach. No differences in overall morbidity and mortality rates were found. The mean length of hospital stay was 3 days shorter in the fast-track group. There were no differences in the 30-day readmission rates. The total cost per patient was significantly lower in the fast-track group (fast-track: 8.107 ± 4.117 euros vs. control: 9.019 ± 4.667 Euros; P=.02). The main factor contributing to the cost reduction was a decrease in hospitalization unit costs.

Conclusion

The application of a multimodal rehabilitation protocol after elective colorectal surgery decreases not only the length of hospital stay but also the hospitalization costs without increasing postoperative morbidity or the percentage of readmissions.
