Evolución del cierre de ileostomía en una unidad de cirugía colorrectal. Análisis comparativo según la técnica

Introduction

The objective of this study is to assess whether the results of loop ileostomy closure in terms of morbidity and hospital stay are influenced by the type of anastomosis and suture used.

Method

All patients who underwent loop ileostomy closure were reviewed. A retrospective cohort study comparing morbidity and hospital stay according to the type of anastomosis (TT/LL) and the type of suture (hand sewn/mechanical) was performed.

Results

From January 2003 to November 2011 a total of 167 loop ileostomy closures were analized. The groups were: type of anastomosis (TT 95/LL 72) and type of suture (manual 105/stapled 62). In 76% of the observed population the underlying disease was cancer. Mortality occurred in one case. The stratified morbidity analysis by type of complications showed no significant differences between the groups in terms of local (7.4% TT, LL 8.3%, 6.7% hand sewn, stapled 9.7%), general (TT 9.5%, 16.7% LL, hand sewn 6.7%, 6.5% stapled) and surgical (TT 15.8%, 19.4% LL, hand sewn 17.1%, 17.7% stapled) complications, nor in the rate of reoperations (TT 6.3%, 6.9% LL, hand sewn 6.7%, 6.5% stapled) and hospital stay in days (TT 7.8, 8 LL, hand sewn 8.6, stapled 6.7)

Conclusions

Closure of loop ileostomy can be performed regardless of the type of suture or anastomosis used, with the same rate of morbidity and hospital stay.     

Resultados de la esofagectomía por cáncer tras la creación de un Comité de Tumores Esofagogástricos

Introduction

Treatment of oesophageal cancer with curative intent requires a multidisciplinary approach. Neoadjuvant therapy, the radicality of resection and extension of lymphadenectomy have been associated with increased operative morbidity and mortality. The aim of this study was to assess the results of surgical treatment of oesophageal cancer since the presence of an interdisciplinary esophagogastric tumour board.

Methods

Patients with cancer of the oesophagus and oesophagogastric junction who underwent oesophagectomy between January 2005 and March 2012 were included in this retrospective study. Data concerning type of resection, postoperative complications, mortality and survival were analysed.

Results

Of the 392 patients with a diagnosis of oesophageal cancer over the study period, 100 underwent oesophagectomy. Seventy-four patients received neoadjuvant treatment. Eighty-two patients underwent transthoracic resection while a transhiatal was used in 10 patients. Colon interposition was required in 8 cases. An R0 resection was achieved in 98 patients. Anastomotic leaks developed in 15 patients, 9 were intrathoracic and 6 were cervical. Postoperative morbidity occurred in 42% of patients, and intra-hospital and 90-day mortality was 2%. Median length of hospital stay was 16 days. The respective actuarial survival at 1 and 5 years were 82% and 56%.

Conclusions

Surgical treatment with curative intention for oesophageal cancer is only possible in a quarter of patients diagnosed. The high morbidity rate was mainly due to intrathoracic complications.     

Morbimortalidad de la resección pancreática

Aim

Assess the postoperative morbidity rates in pancreatic resection.

Material and method

Prospective observational study which includes 117 patients who underwent surgery consecutively due to pancreatic or periampullary tumours. In 61 of the patients, cephalic pancreatectomy was carried out; 15 underwent total pancreatectomy; one underwent enucleation and 40 underwent distal pancreatectomy.

Results

Overall morbidity was 48.7% (59% for cephalic pancreatectomy, 35% for distal pancreatectomy and 46.7% for total pancreatectomy). The most frequent complications were intra-abdominal abscesses and collections (15.38%) and medical complications (13.68%). The incidence of pancreatic fistula was 9.83% for cephalic pancreatectomy and 10% for distal pancreatectomy. The reintervention incidence was 14.53%. Overall mortality was 5.12% (6.56% for cephalic pancreatectomy, 2.5% for distal pancreatectomy and 6.67% for total pancreatectomy). The presence of postoperative complications, the need for reintervention and the fact of being over 70 years of age correlated significantly with mortality.

Discussion

Pancreatic resection has high morbidity rates. Mortality is low and is practically limited to patients older than 70 years.     

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.     

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.     

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.     

Exploración laparoscópica de la vía biliar,lecciones aprendidas tras más de 200 casos

Introduction

Laparoscopic common bile duct exploration (LCBDE) is a reliable, reproducible and cost-effective treatment for common bile duct stones. Several techniques have been described for choledochotomy closure.

Aims

To present our experience and the lessons learned in more than 200 cases of LCBDE.

Patients and methods

Between January 1999 and July 2012, 206 patients with common bile duct stones underwent LCBDE. At the beginning of the series, we performed the closure of the CBD over a T-tube (36 patients), subsequently we favoured closure over an antegrade stent (133 patients) but due to a high incidence of acute pancreatitis in the last 16 patients we have performed primary closure.

Results

The 3 closure groups were matched for age and sex. Jaundice was the most frequent presentation. A total of 185 (88,5%) patients underwent choledochotomy whereas in 17 (8,7%) patients the transcystic route was used. The group that underwent choledochotomy had a larger size of stones compared to the transcystic group (9,7 vs 7,6 mm). In the stented group we found an 11,6% incidence of pancreatitis and 26,1% of hyperamylasemia. In the primary closure group we found a clear improvement of complications and hospital stay. The increased experience of the surgeon and age (younger than 75) had a positive impact on mortality and morbidity.

Conclusions

Primary closure of the common bile duct after LCBDE seems to be superior to closure over a T tube and stents. The learning curve seems to have a positive impact on the outcomes making it a safe and reproducible technique especially for patients aged under 75.     

La influencia del tipo de abordaje torácico sobre el desarrollo de complicaciones respiratorias tras la esofagectomía

Introduction

A systematic review of the literature was performed with the aim to determine differences in the rate of respiratory complications after esophagectomy for esophageal cancer using minimally invasive access vs traditional thoracic access.

Methods

A literature search was performed using Medline and Cochrane Library, identifying studies that compared the 2 types of thoracic access, regardless of the type of abdominal access (laparotomy/laparoscopy). The studies selected described respiratory complications in absolute numbers and different categories. Studies that considered minithoracotomy as a minimally invasive technique were excluded. Inclusion criteria were: studies decribing the different types of respiratory complications (9 in total), and analysing the most common complications: respiratory infection, respiratory failure and pleural effusion.

Results

Nine studies were selected (one prospective randomized trial and 8 case control studies) including 1,190 patients, 1,167 of which were operated on for esophageal cancer: 482 patients by thoracotomy and 708 by thoracoscopy. Three studies included definitions of respiratory complications, and one stratified them. The more frequent complications that allowed a meta-analysis were: respiratory infections, pleural effusion, and respiratory failure. No significant differences were found between the 2 types of access in the global analysis.

Discussion

The type of thoracic access (thoracotomy or thoracoscopy) does not seem to influence the development of respiratory complications after esophagectomy for cancer. However, the design of the studies analysed, the absence of clear definitions and stratification of the complications makes this conclusion questionable. A consensus on the definition of complications and further prospective randomized clinical trials are necessary.     

Pancreatitis aguda durante la gestación,experiencia de 7 años en un centro de tercer nivel

Introduction

Acute pancreatitis is a common cause of acute abdomen in pregnant women. The purpose of this study was to determine the frequency at our institution and its management and outcomes.

Methods

A retrospective analysis of a database of cases presented in 7 consecutive years at a tertiary center was performed.

Results

Between December 2002 and August 2009, there were 19 cases of acute pancreatitis in pregnant women, 85% with a biliary etiology. The highest frequency was in the third trimester of pregnancy (62.5% cases). In cases of gallstone pancreatitis, 43.6% of pregnant women had had previous episodes before pregnancy. A total of 52.6% of the patients were readmitted for a recurrent episode of pancreatitis during their pregnancy. Overall, 26.3% of the patients received antibiotic treatment and 26.3% parenteral nutrition. Laparoscopic cholecystectomy was performed during the 2nd trimester in two patients (10.5%). There was no significant maternal morbidity.

Conclusion

Acute pancreatitis in pregnant women usually has a benign course with proper treatment. In cases of biliary origin, it appears that a surgical approach is suitable during the second trimester of pregnancy.     

Resultados de una encuesta nacional sobre el cierre de la pared abdominal

Objective

To assess knowledge on the abdominal wall closure through a surgeon cohort survey.

Methods

A twenty question individual questionnaire on laparotomy in elective surgery.

Results

A total of 131 surgeons from seven hospitals responded (72% specialists and 28% in training). 71% of respondents estimated the frequency of incisional hernia to be higher than 15% and 54% considered the technique to be the most significant risk factor. 85% considered midline laparotomy closed with slow absorbable suture (57%) in a single layer (66%) to be the most appropriate technique. 67% believed retention sutures to be the appropriate prevention technique. 50% did not know or could not apply the 4:1 technique. 87% considered that an incisional hernia can be prevented and that the technique is the most important factor on which to act. 84% believed that a prosthesis can prevent the occurrence of incisional hernia, whereas 40% of respondents never use it and only 38% use it in patients at risk. On comparing surveys between specialists and residents, significant differences appeared in terms of a better understanding of the theoretical technical aspects in trainee surgeons.

Conclusions

Although the results show an adequate understanding of the epidemiology and risk factors for development of incisional hernia, training and consensus measures are likely to be introduced in some basic technical aspects in order to improve results in laparotomy closure.     

Interposición de intestino delgado entre el colon y el recto como forma de lograr una anastomosis pélvica sin tensión

Purpose

There are some circumstances in which the descending colon does not reach the pelvis to complete a colorectal anastomosis without tension. Re-establishing intestinal continuity by interposing small bowel as a bridge between the colon and the rectum could be an acceptable surgical alternative.

Methods

We describe the interposition of one or two segments of small bowel as a way of restoring continuity of the colon and rectum in three patients in whom it was not possible to perform a colorectal anastomosis without tension due to ischaemic colon, synchronous cancer or difficulty in accessing the supramesocolic space, respectively.

Results

Intestinal continuity was re-established in all patients with no significant morbidity and good intestinal function.

Conclusion

The interposition of small bowel segments between the colon and the rectum should be considered a valid surgical option when it is not possible to achieve a well-perfused, tension-free pelvic colorectal anastomosis.     

Restorative proctocolectomy with and without protective ileostomy in a pediatric population

Purpose

This study aim was to review outcomes of pediatric patients after restorative proctocolectomy with or without a protective ileostomy in the treatment of ulcerative colitis and polyposis syndromes.

Methods

All patients who underwent rectal mucosectomy with ileal pouch reservoir and hand-sewn ileal pouch anal anastomosis (IPAA) during 19-year period were reviewed retrospectively.

Results

Eighty-three patients with ulcerative colitis and 7 patients with polyposis syndromes (ages 2.0-21.8 years) were reviewed. Sixty-eight patients underwent IPAA without diverting ileostomy. Fifty-six patients underwent restorative proctocolectomy as single-stage procedures, and 12 had abdominal colectomy and subsequent definitive IPAA without diverting ileostomy. Nineteen patients had IPAA with diverting ileostomy and subsequent closure of ileostomy. Three-stage procedures were performed in 3 cases. An ileal pouch leak or pelvic abscess occurred in 2 patients. Surgical pouch revision for retraction, efferent limb syndrome, prolapse, pouchitis, or perirectal infections occurred in 19 (6/62 J-pouch, 13/28 S-pouch). Fourteen patients (5/22 with diversion, 9/68 without diversion) developed small bowel obstruction. Overall, daytime and nighttime continence was excellent with rare nocturnal evacuations.

Conclusions

Restorative proctocolectomy without protective ileostomy is not associated with an increased morbidity, even in patients with active colitis, and may be appropriate most patients.     

Estudio comparativo, prospectivo y no aleatorizado de la colecistectomía endoscópica transvaginal frente a la colecistectomía laparoscópica transparietal

Introduction

We present a non-randomised comparative study of two patients series followed up prospectively, in which convention laparoscopic cholecystectomy is compared with transvaginal cholecystectomy, a hybrid transluminal endoscopic procedure, with the objective of assessing the clinical safety of the procedures and its efficacy in the resolution of cholelithiasis.

Patients and method

A non-randomised prospective clinical series of 40 female patients, operated on for cholelithiasis using endoscopic surgery, 20 with a conventional laparoscopic approach and 20 using a transvaginal endoscopic approach. Surgical wound infection, urinary infection, evisceration, eventration, mortality and other complications.

Results

Scheduled operations were performed on the 40 patients as indicated. There were no complications during the operations. There was no mortality associated with the procedures and there was only one post-surgical complication, a urinary tract infection in one patient operated on by the transvaginal approach. The mean follow up was the same in both groups (9 months). The mean hospital stay was less than 0.8 days in both groups. The duration of the surgery was longer in the transvaginal approach group, with a mean of 69.5 min, compared to 46.2 min in the laparoscopy group.

Conclusions

Although the cosmetic benefit is obvious, no differences were found as regards parietal problems in this series. The duration of the transvaginal surgery is higher than that of the transparietal, but the times of both are acceptable. In this study, the non-inferiority in the safety and efficacy of the transvaginal approach is able to be assessed.     

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.     

Seguridad de la colecistectomía laparoscópica temprana (<48 h) para pacientes con pancreatitis aguda biliar leve: revisión sistemática de la literatura y metaanálisis

Background

In mild gallstone pancreatitis, cholecystectomy decreases the risk of recurrence. This should be performed during the initial hospitalization, but even when this is performed, the hospital stay can be prolonged, with an increase in costs and morbidity.The aim of this study is to compare the complication rate between patients who underwent an early cholecystectomy (<48 hours) vs. a late one (>48 hours).

Materials and methods

A systematic search was performed in the following data bases: PubMed, EMBASE, LILACS and Scielo. Articles on patients with acute, mild gallstone pancreatitis who required a cholecystectomy during their initial hospitalization were included and compared with those undergoing a late cholecystectomy, in order to evaluate the complications, number of days of hospitalization and need for readmission. The quality of the studies and the risks of bias were evaluated.

Results

A total of 580 articles and summaries were identified which included 3 observational studies and a randomized clinical trial. A total of 636 patients who underwent a cholecystectomy during the initial hospitalization were included,. Ten of 207 (4.83%) in the early cholecystectomy group showed some type of complication, and 19 of 429 (4.42%) in the late cholecystectomy group, with a risk difference of -0.0016 IC 95% ([-0.04]-0.04).Three of the included studies should be considered of low quality and one of high quality. No publication bias was evidenced.

Conclusion

No differences in complication rate were found between patients who underwent an early cholecystectomy versus a late cholecystectomy; nevertheless, further studies should be carried out in order to confirm these findings.     

Utilidad de la tomografía computarizada para el diagnóstico de lesiones intestinales y mesentéricas en el trauma abdominal cerrado

Background

The frequency of bowel and mesenteric injuries is increasing. They are difficult to diagnose and delays in their diagnosis leads to a significantly increased morbidity and mortality. The aim of this study is to evaluate the usefulness of the computed tomography (CT) in the detection of blunt bowel and mesenteric injuries.

Method

Between January 2000 and October 2007, 79 patients with blunt abdominal trauma (60 men and 19 women) were included in our study. They underwent laparotomy after performing the abdominal CT. The CT findings were compared with the findings at laparotomy in order to determine the accuracy of the CT in the detection of bowel and mesenteric injuries.

Results

For the detection of bowel and mesenteric injuries we obtained for the CT: Sensitivity=84.2%, Specificity=75.6%, Positive Predictive Value =76.2%, Negative Predictive Value =83.8%, Positive Probability Value=3.45 and Negative Probability Value =0.21. Accuracy: 79.7%.

Conclusion

The abdominal CT is suitable for detecting bowel and mesenteric injuries following blunt abdominal trauma.     

Surgeon specialization impacts the management but not outcomes of acute complicated diverticulitis

Background

The management and outcomes of patients receiving nonelective surgical treatment of acute complicated diverticulitis by surgeon specialization have received little attention.

Methods

A retrospective review was performed of consecutive patients with acute complicated diverticulitis who underwent surgery from 2006 to 2013. Patients were analyzed based on surgeon specialty: general surgery (GS) or colorectal surgery (CRS).

Results

One hundred fifteen patients met criteria for study; 62 patients in the CRS and 53 in the GS group. GS were more likely to perform Hartmann's procedures or primary anastomosis and less likely to perform primary anastomosis with diverting ileostomy than CRS. There were no differences between groups for any outcome measures on univariate analysis. CRS patients had shorter operative time (P = .001) and length of stay (P ≤ .001) for stoma reversal procedures. Surgeon specialization was not associated with morbidity, readmission, or length of stay on multivariate analysis.

Conclusions

Although surgical management differed significantly between CRS and GS, comparable outcomes were observed at the index hospital admission.
