The operative management of gallstone ileus

INTRODUCTION

Gallstone ileus is an uncommon entity, which accounts for 1–4% of all presentations to hospital with small bowel obstruction and for up to 25% of all cases in patients over 65 years of age. Despite medical advances over the last 350 years, gallstone ileus is still associated with high rates of morbidity and mortality. The management of gallstone ileus remains controversial. Whilst open surgery has been the mainstay of treatment, more recently other approaches have been employed, including laparoscopic surgery and lithotripsy. However, controversy persists primarily in relation to the extent of surgery performed.

MATERIALS AND METHODS

A literature review was performed in an attempt to discover the optimal surgical treatment of gallstone ileus, particularly the timing of biliary surgery. Published articles were identified from the medical literature by electronic searches of Pubmed and Ovid Medline databases, using the search terms ‘gallstone ileus’, ‘gallstone/intestinal obstruction’ and ‘gallstone/bowel obstruction’. The related articles function of the search engines was also used to maximise the number of articles identified. Relevant articles were retrieved and additional articles were identified from the references cited in these articles.

RESULTS AND CONCLUSIONS

The literature on gallstone ileus is composed entirely of retrospective analysis of small numbers of patients accumulated over many years. The question as to whether one stage or interval biliary surgery should be performed remains unanswered and it is unlikely that further case series will help decision making in the management of gallstone ileus. Whilst many authors conclude that enterolithotomy alone is the best option in most patients, a one-stage procedure should be considered for low-risk patients.     

Management of gallstone ileus

Background/Purpose. Gallstone ileus is an uncommon complication of cholelithiasis in the elderly with a high morbidity and mortality rate. This study aims to clarify the current surgical management. Methods/results. In a retrospective survey over the past 11 years there were 9 patients with gallstone ileus, all elderly (mean age, 77 years), among 2242 cholecystectomies (0.4%) and 243 operated small intestinal obstructions (3.7%). Urgent laparotomy confirmed gallstone obstruction and a cholecystoduodenal (89%) or cholecystocolonic (11%) fistula. The operation included enterolithotomy alone (3 high-risk cases) or plus fistula repair and cholecystectomy (6 cases). There were 3 postoperative complications including wound dehiscence, wound infection, and obstructive jaundice (morbidity, 37.5%) and 1 death due to myocardial infarction (mortality, 11%). On follow-up (mean, 5 years), 6 patients with cholecystectomy (in 1 case it was performed 2 months after the initial operation) and 1 patient with enterolithotomy alone are well; there was 1 death from an unrelated cause after 1 year. Conclusion. It seems that a one-stage procedure (enterolithotomy plus fistula repair and cholecystectomy), when feasible, should be the first choice. Enterolithotomy alone should be reserved for only unstable and difficult cases.     

Gallstone Ileus After Biliointestinal Bypass: Report of Two Cases

Introduction

Gallstone ileus is an uncommon disease and accounts for 1–4 % of all cases of mechanical intestinal obstruction. The physiopathology is related to the presence of a bilioenteric fistula.

Method

We report two cases of gallstone ileus in patients operated on biliointestinal bypass for morbid obesity. The anastomosis of the gallbladder to the proximal end of the bypassed jejunum allowed the transit of gallstones in the excluded ileum and its impaction in anti-reflux valvular system.

Results

Preoperative exams were unable to solve the diagnostic query, and the diagnosis was achieved only at laparotomy. One-stage combined enterolithotomy and cholecystectomy were performed.

Conclusion

The two patients had an uneventful recovery. To our knowledge, this is the first report of gallstone ileus after biliointestinal bypass.     

Laparoscopic versus open colonic resection for complicated diverticular disease in the emergency setting: a safe choice? A retrospective comparative cohort study

Background

We conducted a retrospective cohort study to compare the outcomes of laparoscopic colon resection (LCR) with open colon resection (OCR) for complicated diverticular disease (CDD) during emergent hospital admission.

Methods

Charts from all patients undergoing colon resection for CDD during emergent hospital admission at a single academic institution were reviewed. The primary outcomes were overall 30-day postoperative morbidity and mortality.

Results

From 2000 to 2010, 125 cases were retrieved (49 LCR and 86 OCR). Conversion rate was 5.1%. Overall morbidity significantly decreased with laparoscopic surgery compared with OCR. No mortality occurred with LCR. Prolonged ileus was less frequent (12.8% vs 32.6%; P = .02), time to oral intake shorter (3 vs 6 days; P < .01), and LOS shorter (5 vs 8 days; P = .05) for LCR.

Conclusions

In our series, in the patients selected, LCR for CDD during emergent hospital admission appears to be a safe procedure associated with decreased morbidity, time to oral intake, and LOS compared with OCR.     

A review of the management of gallstone disease and its complications in pregnancy

Background

Symptomatic gallstone disease is the second most common abdominal emergency in pregnant women. There have been significant developments in the management of gallstone disease, but risk to the fetus has prevented their routine application in pregnant women. We reviewed the literature to find the current best evidence for the management of gallstones and its complications in pregnancy.

Data sources

MEDLINE and PubMed literature searches were performed to identify original studies.

Results and Conclusions

Six studies comparing conservative with surgical management of cholecystitis showed no significant difference in incidence of preterm delivery (3.5% vs 6.0%, P = .33) or fetal mortality (2.2% vs 1.2%, P = .57). There was no maternal or fetal mortality in 20 reports of laparoscopic cholecystectomy and 9 reports of endoscopic retrograde cholangiopancreatography, thus indicating their safety when performed with necessary precautions. Laparoscopic cholecystectomy is a safe procedure in all trimesters. In 12 reports of gallstone pancreatitis, fetal mortality was 8.0% versus 2.6% (P = .28) in conservative and surgical groups, respectively, suggesting the need for earlier surgical intervention.     

Feeding jejunostomy during Whipple is associated with increased morbidity

Background

Placement of a feeding jejunostomy tube (FJ) is often performed during pancreaticoduodenectomy (PD). Few studies, however, have sought to determine whether such placement affects postoperative outcomes after PD.

Materials and methods

This is a retrospective analysis of the National Surgical Quality Improvement Program (NSQIP) database to determine the 30-d-postoperative mortality rate, major complication rate, and overall complication rate of jejunostomy tube placement at the time of PD. Univariate and multivariate comparison of postoperative outcomes between patients with and without FJ placement during PD was performed on a total of 4930 patients.

Results

Thirty-day-postoperative mortality did not differ between the two groups (4.0% for patients with FJ versus 2.7% without, P = 0.13), whereas overall morbidity (43.3% with FJ versus 34.6% without, P < 0.0001) and serious morbidity (29.5% with FJ versus 22.8% without, P < 0.0001) were significantly higher in patients undergoing FJ placement during PD. The specific complications that occurred more frequently in FJ patients than patients without FJ included deep space surgical site infection, pneumonia, unplanned reintubation, acute renal failure, and sepsis.

Conclusion

Although FJ placement during PD is considered to be routine at many institutions, our analysis of data from NSQIP suggest that FJ placement may be associated with increased postoperative morbidity.     

Enhanced postoperative recovery pathways in emergency surgery: a randomised controlled clinical trial

Background

Enhanced recovery pathways are now widely used in elective surgical procedures. The feasibility of enhanced postoperative recovery pathways in emergency surgery for perforated peptic ulcer disease was investigated in this randomized controlled clinical trial.

Methods

Patients with perforated peptic ulcer disease who underwent laparoscopic repair were randomized into 2 groups. Group 1 patients were managed with standard postoperative care and group 2 patients with enhanced postoperative recovery pathways. The primary endpoints were the length of hospital stay and morbidity and mortality.

Results

Forty-seven patients were included in the study. There were 26 patients in group 1 and 21 in group 2. There were no significant differences in the morbidity and mortality rates, whereas the length of hospital stay was significantly shorter in group 2.

Conclusions

The application of enhanced postoperative recovery pathways in selected patients with perforated peptic ulcer disease who undergo laparoscopic Graham patch repair seems feasible.     

Comparison of laparoscopic versus open adrenalectomy: results from American College of Surgeons-National Surgery Quality Improvement Project

Background

Although the existing literature suggests that laparoscopic adrenalectomy may be associated with less postoperative morbidity than open adrenalectomy, a comparison of the two approaches has not been published using American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) data. The objective of our analysis was to compare the 30-d outcomes after laparoscopic versus open adrenalectomy using this data source.

Methods

The ACS-NSQIP Participant User Files for 2005–2010 were used for this retrospective analysis, which included all patients with (1) a primary Current Procedural Terminology code for open or laparoscopic adrenalectomy and (2) a postoperative International Classification of Diseases, Ninth Revision (ICD-9) code for adrenal gland pathology. Primary outcomes were 30-d postoperative mortality, overall complication rate, and length of postoperative hospitalization. The association between surgical approach and primary outcomes were determined after adjusting for a comprehensive array of patient- and procedure-related factors.

Results

A total of 3100 patients were included for analysis (644 undergoing open versus 2456 undergoing laparoscopic adrenalectomy). Patients undergoing a laparoscopic procedure had significantly lower postoperative morbidity and shorter length of stay than patients undergoing an open procedure after adjustment for patient- and procedure-related factors. Similar findings were demonstrated for all indications, including malignancy.

Conclusions

To our knowledge, the present study represents the largest comparison to date of laparoscopic versus open adrenalectomy. Our findings suggest that the laparoscopic approach is associated with sizeable reductions in postoperative morbidity and length of postoperative hospitalization.     

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.     

A forgotten cause of intestinal obstruction in a 96-year-old female

Aim-Background

Gallstone ileus is a mechanical bowel obstruction caused by a biliary calculus originating from a bilioenteric fistula. It is a rare surgical disease and occurs in the elderly with female propensity.

Case presentation

We report the case of a 96-year-old female patient, 6 gravida, 6 para who was admitted to our clinic for abdominal pain, vomiting, constipation and flatulence. The patient underwent an exploratory laparoscopy with a midline incision. Intraoperatively, a gallstone measuring 5x3x2.6 cm was found in the ileum 80 cm from the ileocaecal valve. The stone was extracted by means of a longitudinal enterotomy. The postoperative course was uneventful.

Conclusion

Gallstone ileus is an uncommon disease. Exploratory laparotomy with enterolithotomy offers advantages in cases of elderly patients with diagnostic delay. With the advancements of surgical technology (lithotripsy, endoscopy), treatment has taken a step forward, providing reasonable options for gallstone obstruction. The patient’s performance status should be considered (tolerance of major surgical procedure), before proceeding with any of the current operative options.     

An analysis of omitting biliary tract imaging in 668 subjects admitted to an acute care surgery service with biochemical evidence of choledocholithiasis

Background

No consensus exists for the timing and utility of biliary imaging in patients with preoperative concern for choledocholithiasis.

Methods

Admissions to an acute care surgery service with evidence of choledocholithiasis undergoing same-admission cholecystectomy without preoperative or intraoperative imaging were identified. One-way analysis of variance on the log-transformed outcomes, with the Tukey-Kramer multiple comparison procedure, were used to compare means between groups.

Results

A total of 668 patients with elevated but downtrending liver enzymes underwent cholecystectomy without preoperative or intraoperative imaging. Thirty-eight patients (5.7%) had postoperative biliary imaging, of whom 22 (3.3%) had definite choledocholithiasis. One case of postoperative cholangitis occurred which required readmission and endoscopic retrograde cholangiopancreatography with no long-term morbidity. Presenting liver enzymes were significantly higher in the group found to have retained stones postoperatively than those without retained stones.

Conclusions

Patients presenting with biochemical evidence of choledocholithiasis who downtrend preoperatively can be safely managed by cholecystectomy with omission of biliary tract imaging.     

Cholecystostomy offers no survival benefit in patients with acute acalculous cholecystitis and severe sepsis and shock

Background

Acute acalculous cholecystitis is often managed with cholecystectomy or cholecystostomy, but data guiding surgical practice are lacking.

Materials and methods

Longitudinal analysis of the California Office of Statewide Health Planning and Development Patient Discharge Data was performed from 1995–2009. Patients with acute acalculous cholecystitis were identified by International Classification of Diseases 9 code. Cox proportional hazard analysis found predictors of time to death, adjusting for patient demographics, sepsis, shock, frailty, Charlson comorbidity index, length of stay, insurance status, teaching hospital status, and year.

Results

Of 43,341 patients, 63.5% received a cholecystectomy, 2.8% received a cholecystostomy, and 1.2% received both. Overall, 30.4% of patients died, with higher mortality among patients with cholecystostomy (61.7%) or no procedure (42.0%) than cholecystectomy (23.0%). In patients with severe sepsis and shock, there was no difference in survival of patients with cholecystostomy versus no intervention (hazard ratio [HR] 1.13, P = 0.256), although patients with cholecystectomy (with or without prior cholecystostomy) had improved survival (HR 0.29, P < 0.001; HR 0.56, P < 0.001). Results were similar among patients on the ventilator >96 h.

Conclusions

Although cholecystostomy offered no survival benefit for patients with severe sepsis and shock, cholecystectomy offered improved survival compared with patients without surgical management. Cholecystostomy may not benefit the sickest patients in whom cholecystectomy may never be considered.     

Comparison of laparoscopic common bile duct exploration and endoscopic retrograde cholangiopancreatography plus laparoscopic cholecystectomy for choledocholithiasis: a prospective randomized study

Background

Endoscopic retrograde cholangiopancreatography and laparoscopic common bile duct exploration are safe and efficient methods that have recently been used for the treatment of bile duct stones. The aim of this study was to compare the efficacy, safety, and surgical outcomes of the laparoscopic common bile duct exploration plus laparoscopic cholecystectomy (LCBDE+LC) and endoscopic retrograde cholangiopancreatography plus laparoscopic cholecystectomy (ERCP+LC).

Methods

One hundred twenty patients were prospectively randomized into 2 groups: LCBDE with LC in a single intervention and LC after ERCP.

Results

The success rate of the LCBDE+LC group (96.5%) was found to be higher than for the ERCP+LC group (94.4%). Complication rates of the LCBDE+LC and ERCP+LC group were 7% and 11.1%, respectively. Complications requiring ERCP in the postoperative period after LCBDE+LC have been noted in 3.5% of cases.

Conclusions

Laparoscopic CBD exploration provides an alternative therapeutic approach that has less morbidity, is cost-effective, and allows earlier recovery with a reduced period of short-term disability.     

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.     

Cholecystectomy and Wound Complications: Smoking Worsens Risk

Background

In the United States, approximately 800,000 cholecystectomies are performed annually. We sought to determine the influence of preoperative smoking on postcholecystectomy wound complication rates.

Materials and methods

Using the National Surgical Quality Improvement Program database (2005–2011), patients aged ≥18 y who underwent elective open or laparoscopic cholecystectomy (LC) for benign gallbladder disease were identified using current procedural terminology codes. Multivariate regression was performed to determine the association between smoking status and wound complications, by surgical approach.

Results

Of 143,753 identified patients, 128,692 (89.5%) underwent LC, 27,788 (19.3%) were active smokers, and 100,710 (70.2%) were females. Active smokers were younger than nonsmokers (mean + standard deviation age: 44.2 (14.9) versus 51.6 (17.9) years); P < 0.001) and had fewer comorbidities. Within 30-d postcholecystectomy, wound complications were reported in 2011 (1.4%) patients. Compared with nonsmokers, active smokers demonstrated increased odds of wound complications after both open cholecystectomy (odds ratio 1.28; P = 0.010) and LC (odds ratio 1.20; P = 0.020) after adjustment for demographic and clinical characteristics. Having wound complications increased the average postoperative length of stay by 2–4 d (P <0.001).

Conclusions

Active smokers are more likely to develop wound complications after cholecystectomy, regardless of surgical approach. Occurrence of wound complications consequently increases postoperative length of stay. Smoking abstinence before cholecystectomy may reduce the burden associated with wound complications.     

Synchronous splenectomy during cholecystectomy for hereditary spherocytosis: Is it really necessary?

Background/Purpose

Expert guidelines recommend performing synchronous splenectomy in patients with mild hereditary spherocytosis (HS) and symptoms of gallstone disease. This recommendation has not been widely explored in the literature. The aim of this study is to determine if our data support expert opinion and if different practice patterns should exist.

Methods

This is an IRB-approved retrospective study. All HS patients under 18 years of age who underwent cholecystectomy for symptomatic gallstones at a single institution between 1981 and 2009 were identified. Patients who underwent cholecystectomy without concurrent splenectomy were reviewed retrospectively for future need for splenectomy and evidence of recurrent gallstone disease.

Results

Of the 32 patients identified, 27 underwent synchronous splenectomy. The remaining 5 patients underwent cholecystectomy without splenectomy and had a mean age of 9.4 years. One of the 5 patients eventually required splenectomy for left upper quadrant pain. None of the remaining 4 required hospitalization for symptoms related to hemolysis or hepatobiliary disease. Median follow-up is 15.6 years.

Conclusion

The need for splenectomy in patients with mild HS and symptomatic cholelithiasis should be assessed on a case by case basis. Our recommendation is to not perform synchronous splenectomy in conjunction with cholecystectomy for these patients if no indication for splenectomy exists.     

Low-pressure versus standard-pressure pneumoperitoneum for laparoscopic cholecystectomy: a systematic review and meta-analysis

Background

The feasibility and safety of low-pressure pneumoperitoneum in laparoscopic cholecystectomy remain unclear.

Methods

A meta-analysis of randomized controlled trials comparing low-pressure with standard-pressure pneumoperitoneum was performed.

Results

A total of 1,263 patients were included. Low-pressure pneumoperitoneum was associated with significantly decreased postoperative pain. The requirement for increased pressure was significantly greater in the low-pressure group (risk ratio = 6.16; P < .001). Operative time was similar, with only a slight statistical significance (weighted mean difference = 2.07; P < .001). Length of hospital stay was shorter in the low-pressure group (weighted mean difference = −.27; P = .01). No significant differences were found in surgical complications or conversion to open surgery.

Conclusions

Low-pressure pneumoperitoneum is feasible and safe and results in reduced postoperative pain and near-equal operative time compared with standard-pressure pneumoperitoneum. More studies are required to investigate the potential benefits of the reduced length of hospital stay.     

Impact of a blood conservation program on 30-day morbidity and mortality: a cohort study

Background

There are little published data on outcomes of blood conservation (BC) patients after noncardiac surgery. The objective of this study was to compare the surgical outcomes of patients enrolled in our BC program with that of the general population of surgical patients.

Methods

BC patients at our institution undergoing various surgical procedures were identified from the 2007–2009 National Surgical Quality Improvement Program database and compared with a cohort of conventional care (CC) patients matched by age, gender, and surgical procedure. Univariate and multiple logistic regression analyses were performed to evaluate 30-d postoperative outcomes.

Results

One hundred twenty BC patients were compared with 238 CC patients. The two groups were similar for all preoperative variables except smoking, which was lower in the BC group. On univariate analysis, BC patients had similar mean operating time (148 versus 155 min; P = 0.5), length of stay (5.9 versus 5.5 d; P = 0.7), and rate of return to the operating room (7.5% versus 5.5%; P = 0.4) compared with CC patients. BC and CC patients had similar 30-d morbidity (18% versus 14%; P = 0.3) and mortality rates (1.6% versus 1.3%; P = 1.0), respectively. On multivariable analysis, enrollment in the BC program had no impact on postoperative 30-d morbidity (odds ratio, 1.78; 95% confidence interval, 0.71–4.47) or 30-d mortality (unadjusted odds ratio, 1.33; 95% confidence interval, 0.22–8.05).

Conclusions

Short-term postoperative outcomes in BC patients are similar to the general population, and these patients should not be denied surgical treatment based on their unwillingness to receive blood products.     

La préhabilitation. Préparer les patients à la chirurgie pour améliorer la récupération fonctionnelle et réduire la morbidité postopératoire

Objective

Prehabilitation consists in providing a repetitive physical exercise before surgery to improve the postoperative recovery course. This review aims to evaluate the feasibility and the expected benefits of prehabilitation on the postoperative recovery course and the reduction of the postoperative morbidity.

Data sources

Data research has focused on English-language articles in the Medline database, published from 1989 to 2013. Keywords, used separately or in combination, were: prehabilitation, functional capacity, postoperative morbidity, physical activity.

Study selection

Selected articles were original articles, clinical cases, review articles and meta-analysis.

Data extraction

Articles were analyzed for feasibility, benefits and limitations of preoperative physical preparation techniques.

Data synthesis

Poor preoperative functional status is associated with increased postoperative morbidity. Elderly are more prone to postoperative complications. The improvement of preoperative physical status of these patients is possible and may reduce morbidity and allow faster recovery after major surgery. In order to improve efficiency, the training program must provide endurance and muscle reinforcement exercises, whose intensity must be adapted to the patient's baseline physical abilities. An average of three sessions per week over a period of six to eight weeks before surgery seemed a good compromise between feasibility and effectiveness.

Conclusion

The effectiveness of prehabilitation has been demonstrated in cardiovascular surgery and probably in abdominal surgery. Prehabilitation must be integrated into the overall patient medical management, and must be associated with preoperative refeeding and postoperative rehabilitation protocols. By optimizing all stages of the surgical patient management, from diagnosis to recovery, prognosis of high-risk surgical patients could be improved.     

Morbilidad y mortalidad de la ileostomía derivativa temporal en la cirugía por cáncer de recto

Introduction

A temporary diverting ileostomy is frequently used to reduce the consequences of a distal anastomotic leakage after total mesorectal excision in rectal cancer surgery. This surgical technique is associated with high morbidity and a not negligible mortality. The aim of this study is to evaluate the morbidity and mortality rate associated with an ileostomy and its posterior closure.

Material and methods

Between 2001 and 2012, 96 patients with temporary diverting ileostomy were retrospectively analyzed. Morbidity and mortality were analyzed before and after the stoma closure. The studied variables included age, sex, comorbidities, time to bowel continuity restoration and adjuvant chemotherapy.

Results

In 5 patients the stoma was permanent and another 5 died. The morbidity and mortality rates associated with the stoma while it was present were 21 and 1% respectively. We performed a stoma closure in 86 patients, 57% of whom had previously received adjuvant therapy. There was no postoperative mortality after closure and the morbidity rate was 24%. The average time between initial surgery and restoration of intestinal continuity was 152.2 days. This interval was significantly higher in patients who had received adjuvant therapy. No statistically significant difference was found between the variables analyzed and complications.

Conclusions

Diverting ileostomy is associated with low mortality and high morbidity rates before and after closure. Adjuvant chemotherapy significantly delays bowel continuity restoration, although in this study did not influence in the rate of complications.
