Evaluación de la seguridad y satisfacción de los pacientes en un programa de colecistectomía laparoscópica ambulatoria con criterios expandidos

Introduction

The good results obtained with the implementation of ambulatory laparoscopic cholecystectomy programs have led to the expansion of the initial inclusion criteria. The main objective was to evaluate the results and the degree of satisfaction of the patients included in a program of laparoscopic cholecystectomy without admission, with expanded criteria.

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.     

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.     

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.     

Evolución psicológica de los pacientes afectos de obesidad mórbida intervenidos mediante una gastrectomía tubular

Background

The aim of this study is to observe the psychological changes at one year postop in a group of patients undergoing laparoscopic vertical sleeve gastrectomy (GVL) and multidisciplinary follow- up.

Methods

A total of 46 patients with a BMI-35 or higher, who were selected for GVL, completed psychological testing. After GVL surgery, patients received psychological, nutritional, and medical attention during 12 months, and they retook the same tests.

Results

Psychological tests showed an improvement on almost all scales tested, except perfectionism. The most significant change was in the benchmark for Eating Disorders with an improvement of 89% for bulimia (P<.01), and 55% for body dissatisfaction (P<.01) and ineffectiveness (P<.01). In quality of life there was an improvement of 57% in the change in health status (P<.01).

Conclusion

During our study, a protocol involving GVL and multidisciplinary follow-ups seems proved to be an effective intervention for improving bulimic symptoms and quality of living. The results of these psychological changes are similar to Roux-en-Y Gastric bypass but different to vertical banded gastroplasty or adjustable gastric band, according to previous studies. However, long-term studies are necessary to confirm this trend.     

Programa de formación del residente de cirugía en un laboratorio experimental de cirugía minimamente invasiva (CENDOS)

Introduction

The rapid development of laparoscopic surgery makes resident training programmes necessary.

Objective

To analyse the results of a structured programme of laparoscopic training in an experimental laboratory.

Material and method

From 2003 until 2007, we trained 11 general surgery residents for 20 h every 3 months, for three years. The practice consisted of suture and anastomosis in Endo-Trainer with animal organs, as well as laparoscopic techniques in live animals. In the Endo-Trainer practice we evaluated the time and quality of anastomosis performance. In laparoscopic techniques (cholecystectomy and anti-reflux surgery) a task table was evaluated, from 0 (no errors) to 100 (severe lesion).

Results

In total, 314 anastomosis were performed by the 11 residents, with a median of 28.5 per resident (24-42). The mean time for the first gastro-jejunal anastomosis was 135 min (100-140) and 65 min (57.5-105) for the first jejunal-jejunal anastomosis. Maximum learning was achieved after 45 training hours. There wer no appreciable ifferences between both types of anastomosis. There was inadequate anastomosis quality due to leakage in 17.1% during the learning period and 13.7% during the consolidation period. In the animal, 172 procedures were performed. In cholecystectomy and anti-reflux surgery the mean scores were 2.4 and 5.6 points, respectively. In the remaining procedures, subjectively evaluated by the monitors, the quality was adequate in 65%, deficient in 22% and highly deficient in 13%.

Conclusions

This structured programme of laparoscopic skills based on intestinal anastomosis allows for quicker resident training.     

Análisis de la morbilidad postoperatoria en pacientes con adenocarcinoma gástrico tratados según protocolo de quimiorradioterapia preoperatoria y cirugía

Introduction

The impact of neoadjuvant treatment on the postoperative complications in stomach cancer is a subject of controversy. The aim of this study is to analyse the post-surgical morbidity and mortality in a group of patients who were treated using a chemoradiotherapy protocol before surgery, as well as to identify the possible risk factors that may be associated with the development of complications.

Material and methods

Patients diagnosed with locally advanced gastric adenocarcinoma between June 2005 and June 2008 were operated on in our Centre after having followed a preoperative chemoradiotherapy protocol. Data on postoperative morbidity and mortality were collected retrospectively and the dependent variables associated with the patients, the type of intervention and the tumour characteristics were analysed.

Results

A total of 40 patients were evaluated. The overall morbidity and mortality was 32.5% (13 patients) and 2.5% (1 patient), respectively. The most frequent complications were pneumonia in 12.9% and sepsis due to the catheter in 9.7% of the patients. The risk factors for the development of complications were the body mass index (BMI 25 kg/m²) and the inclusion of the pancreas and/or spleen in the resection.

Conclusions

Preoperative treatment with chemoradiotherapy in patients with locally advanced stomach cancer does not increase the incidence of post-surgical complication. The preoperative condition of the patient (BMI) and extending the surgery to the spleen and pancreas are prognostic factors of early postoperative complications.     

Mamoplastia de reducción en la cirugía del cáncer de mama

Reduction mammaplasty techniques enable the breast cancer surgeon to provide an integral surgical treatment, thus significantly increasing and improving surgical options. These techniques are used to correct problems after the conservative treatment of type 1 breast cancer and to achieve symmetry between the breasts after mastectomy. They are also the basis of cosmetic reconstruction techniques in conservative oncoplastic surgery.     

Carcinoma broncogénico en pacientes con trasplante de órgano sólido. Papel de la cirugía

Background

The incidence of neoplastic diseases is higher in patients undergoing solid organ transplant. However, the incidence of bronchogenic carcinoma (BC) is controversial. The objective of our study was to determine the incidence of BC in a large cohort of transplant patients and the role of surgery.

Material and methods

Until December 2006, 3596 patients underwent solid organ transplant at our institution; 24 (0.7%) patients subsequently developed BC, of which 6 (24%) were classified as clinical stage I and submitted to surgical treatment. Survival was estimated by the Kaplan-Meier method.

Results

Three patients received a liver transplant, two a kidney transplant and one a heart transplant. All were male and all had a smoking history. Mean age was 58.6 years. Two patients had cough, one accompanied by bloody expectoration, and BC was an incidental finding in the remaining cases. The interval between transplant and diagnosis of BC was 38.1 months. Epidermoid carcinoma was the most frequent histological type. Mean tumour size was 3.6 cm (range, 1.3-6). One tumour was classified as pathological stage IA, four as stage IB and one as IIB due to parietal pleural invasion. No patient died during the perioperative period and only one had a haemothorax which resolved with chest tube drainage. Mean hospital stay was 8.5 days (range, 7-11). The immunosuppression regimen was maintained continuously. In subsequent follow-up, one patient died from BC metastasis, one from sepsis, one from chronic renal failure, and three remained alive. The probability of survival at 5 years was 40%, and median survival was established at 5 years.

Conclusions

The incidence of BC in patients undergoing solid organ transplant and the proportion of patients diagnosed in early stages does not differ from non-transplant patients diagnosed with BC, which questions the role of immunosuppression in the genesis and aggressiveness of BC in transplant patients. Surgery may offer acceptable results in early stages, with acceptable rates of perioperative morbidity and mortality.     

Medidas de prevención de la infección del sitio quirúrgico en cirugía abdominal. Revisión crítica de la evidencia

Surgical site infection (SSI) is associated with prolonged hospital stay, increased morbidity, mortality and sanitary costs, and reduced patients quality of life. Many hospitals have adopted guidelines of scientifically-validated processes for prevention of surgical site and central-line catheter infections and sepsis. Most of these guidelines have resulted in an improvement in postoperative results. A review of the best available evidence on these measures in abdominal surgery is presented. The best measures are: avoidance of hair removal from the surgical field, skin decontamination with alcoholic antiseptic, correct use of antibiotic prophylaxis (administration within 30-60 min before incision, use of 1^st or 2^nd generation cephalosporins, single preoperative dosis, dosage adjustments based on body weight and renal function, intraoperative re-dosing if the duration of the procedure exceeds 2 half-lives of the drug or there is excessive blood loss), prevention of hypothermia, control of perioperative glucose levels, avoid blood transfusion and restrict intraoperative liquid infusion.
