Perforated peptic ulcer: clinical presentation, surgical outcomes, and the accuracy of the Boey scoring system in predicting postoperative morbidity and mortality

Global 30-day morbidity and mortality of surgery for perforated peptic ulcer: GRACE study

BACKGROUND

There is little international data on morbidity and mortality of surgery for perforated peptic ulcer (PPU). This study aimed to understand the global 30-day morbidity and mortality of patients undergoing surgery for PPU and to identify variables associated with these.

METHOD

We performed an international study of adults (≥ 18 years) who underwent surgery for PPU from 1st January 2022 to 30th June 2022. Patients who were treated conservatively or had an underlying gastric cancer were excluded. Patients were divided into subgroups according to age (≤ 50 and > 50 years) and time from onset of symptoms to hospital presentation (≤ 24 and > 24 h). Univariate and Multivariate analyses were carried out to identify factors associated with higher 30-day morbidity and mortality.

RESULTS

 1874 patients from 159 centres across 52 countries were included. 78.3% (n = 1467) of the patients were males and the median (IQR) age was 49 years (25). Thirty-day morbidity and mortality were 48.5% (n = 910) and 9.3% (n = 174) respectively. Median (IQR) hospital stay was 7 (5) days. Open surgery was performed in 80% (n = 1505) of the cohort. Age > 50 years [(OR = 1.7, 95% CI 1.4-2), (OR = 4.7, 95% CI 3.1-7.6)], female gender [(OR = 1.8, 95% CI 1.4-2.3), (OR = 1.9, 95% CI 1.3-2.9)], shock on admission [(OR = 2.1, 95% CI 1.7-2.7), (OR = 4.8, 95% CI 3.2-7.1)], and acute kidney injury [(OR = 2.5, 95% CI 1.9-3.2), (OR = 3.9), 95% CI 2.7-5.6)] were associated with both 30-day morbidity and mortality. Delayed presentation was associated with 30-day morbidity [OR = 1.3, 95% CI 1.1-1.6], but not mortality.

CONCLUSIONS

This study showed that surgery for PPU was associated with high 30-day morbidity and mortality rate. Age, female gender, and signs of shock at presentation were associated with both 30-day morbidity and mortality.

Risk Factors for Postoperative Morbidity, Suture Insufficiency, Re-Surgery and Mortality in Patients with Gastroduodenal Perforation

(1) Background: The aim of the present study was to identify risk factors associated with postoperative morbidity, suture/anastomotic insufficiency, re-surgery, and mortality in patients undergoing surgery for gastroduodenal perforation. (2) Methods: A retrospective analysis of 273 adult patients who received surgical treatment for gastroduodenal perforation from January 2006 to June 2021 at the University Hospital Erlangen was performed. The patient demographics and preoperative, intraoperative, and postoperative parameters were collected and compared among the different outcome groups (in-hospital morbidity, suture/anastomotic insufficiency, re-surgery, and 90-day mortality). (3) Results: In-hospital morbidity, suture/anastomotic insufficiency, need for re-surgery, and 90-day mortality occurred in 71%, 10%, 26%, and 25% of patients, respectively. The independent risk factors for morbidity were a significantly reduced general condition, a lower preoperative hemoglobin level, and a higher preoperative creatinine level. The independent risk factors for suture/anastomotic insufficiency could be identified as an intake of preoperative steroids and a perforation localization in the proximal stomach or duodenum. The four parameters were independent risk factors for the need for re-surgery: a significantly reduced general condition, a perforation localization in the proximal stomach, a higher preoperative creatinine level, and a higher preoperative CRP level. An age over 66 years and a higher preoperative CRP level were independent risk factors for 90-day mortality. (4) Conclusions: Our study could identify relevant risk factors for the postoperative outcome of patients undergoing surgical treatment for gastroduodenal perforation. Patients exhibiting the identified risk factors should receive heightened attention in the postoperative period and may potentially benefit from personalized and tailored therapy.

Predicting in-hospital mortality risk for perforated peptic ulcer surgery: the PPUMS scoring system and the benefit of laparoscopic surgery: a population-based study

BACKGROUND

The major treatment for perforated peptic ulcers (PPU) is surgery. It remains unclear which patient may not get benefit from surgery due to comorbidity. This study aimed to generate a scoring system by predicting mortality for patients with PPU who received non-operative management (NOM) and surgical treatment.

METHOD

We extracted the admission data of adult (≥ 18 years) patients with PPU disease from the NHIRD database. We randomly divided patients into 80% model derivation and 20% validation cohorts. Multivariate analysis with a logistic regression model was applied to generate the scoring system, PPUMS. We then apply the scoring system to the validation group.

RESULT

The PPUMS score ranged from 0 to 8 points, composite with age (< 45: 0 points, 45-65: 1 point, 65-80: 2 points, > 80: 3 points), and five comorbidities (congestive heart failure, severe liver disease, renal disease, history of malignancy, and obesity: 1 point each). The areas under ROC curve were 0.785 and 0.787 in the derivation and validation groups. The in-hospital mortality rates in the derivation group were 0.6% (0 points), 3.4% (1 point), 9.0% (2 points), 19.0% (3 points), 30.2% (4 points), and 45.9% when PPUMS > 4 point. Patients with PPUMS > 4 had a similar in-hospital mortality risk between the surgery group [laparotomy: odds ratio (OR) = 0.729, p = 0.320, laparoscopy: OR = 0.772, p = 0.697] and the non-surgery group. We identified similar results in the validation group.

CONCLUSION

PPUMS scoring system effectively predicts in-hospital mortality for perforated peptic ulcer patients. It factors in age and specific comorbidities is highly predictive and well-calibrated with a reliable AUC of 0.785-0.787. Surgery, no matter laparotomy or laparoscope, significantly reduced mortality for scores <  = 4. However, patients with a score > 4 did not show this difference, calling for tailored approaches to treatment based on risk assessment. Further prospective validation is suggested.

Machine Learning for Postoperative Continuous Recovery Scores of Oncology Patients in Perioperative Care with Data from Wearables

Assessing post-operative recovery is a significant component of perioperative care, since this assessment might facilitate detecting complications and determining an appropriate discharge date. However, recovery is difficult to assess and challenging to predict, as no universally accepted definition exists. Current solutions often contain a high level of subjectivity, measure recovery only at one moment in time, and only investigate recovery until the discharge moment. For these reasons, this research aims to create a model that predicts continuous recovery scores in perioperative care in the hospital and at home for objective decision making. This regression model utilized vital signs and activity metrics measured using wearable sensors and the XGBoost algorithm for training. The proposed model described continuous recovery profiles, obtained a high predictive performance, and provided outcomes that are interpretable due to the low number of features in the final model. Moreover, activity features, the circadian rhythm of the heart, and heart rate recovery showed the highest feature importance in the recovery model. Patients could be identified with fast and slow recovery trajectories by comparing patient-specific predicted profiles to the average fast- and slow-recovering populations. This identification may facilitate determining appropriate discharge dates, detecting complications, preventing readmission, and planning physical therapy. Hence, the model can provide an automatic and objective decision support tool.

A comparative study of laparoscopic versus laparotomy repair of perforated peptic ulcer: A prospective study

Background

Laparoscopic surgery is still gaining popularity in conditions associated with peritonitis, such as a perforated peptic ulcer.

Aim of the work

This study aimed to compare laparoscopic and laparotomy repair of perforated peptic ulcers regarding intraoperative parameters, postoperative pain, time of the start of oral feeding, postoperative complication, hospital stay, resuming normal activity, and outcomes.

Patients and methods

This is a prospective study of 50 patients (males and females), of any age with perforated peptic ulcer. Those patients will be divided by the random serial number method into two groups: the laparoscopic group and the open (laparotomy) group. In a period from 15th April 2022 to 15th February 2023 data related to patients were recorded and subjected to analysis.

Results

All patients were divided into two groups: Laparoscopic group with 25 patients (23 of them underwent successful laparoscopic repair and two patients were converted to open) and the open (laparotomy) group with 25 patients underwent laparotomy repair (of which 23 patients were living, and two patients died on the third and tenth postoperative days). There were no significant differences in baseline characteristics between both groups in terms of age, gender, special habits, preoperative risk factors, comorbidities, laboratory, and radiological findings; also both groups showed insignificant differences regarding the American Society of Anesthesiologists (ASA) scores (P=0.83), total Boey’s score (P=0.77), shock on admission (P= 1.00), and the duration of symptoms > 24 hours (P= 0.77). Operative time was significantly increased in the laparoscopic versus open group (P=0.0001). While, first-day pain score (VAS), opioid requirements, time of starting oral feeding, length of hospital stay, and return to normal activity were highly significantly decreased in laparoscopic repair compared with open repair (P= <0.0001 for each). Total postoperative complications showed insignificant difference between the studied groups (P=0.16), but they were more prevalent between the open group (14 patients, 56%) versus the laparoscopic group (9 patients, 36%). Good cosmetic results of wounds were more prevalent in the laparoscopic group [20 patients (80.00%)] than the open group [13 patients (56.52%)], but insignificant, P=0.17.

Conclusion

Laparoscopic repair had an upper hand over open repair regarding less intraoperative blood loss, less postoperative pain, requiring less postoperative analgesia, early starting of oral feeding, less postoperative complications, shorter hospital stay, early return to normal activity, and good cosmetic results of wounds.

Perforated peptic ulcer (PPU) treatment: an Italian nationwide propensity score-matched cohort study investigating laparoscopic vs open approach

BACKGROUND

Perforated peptic ulcer (PPU) remain a surgical emergency accounting for 37% of all peptic ulcer-related deaths. Surgery remains the standard of care. The benefits of laparoscopic approach have been well-established even in the elderly. However, because of inconsistent results with specific regard to some technical aspects of such technique surgeons questioned the adoption of laparoscopic approach. This leads to choose the type of approach based on personal experience. The aim of our study was to critically appraise the use of the laparoscopic approach in PPU treatment comparing it with open procedure.

METHODS

A retrospective study with propensity score matching analysis of patients underwent surgical procedure for PPU was performed. Patients undergoing PPU repair were divided into: Laparoscopic approach (LapA) and Open approach (OpenA) groups and clinical-pathological features of patients in the both groups were compared.

RESULTS

A total of 453 patients underwent PPU simple repair. Among these, a LapA was adopted in 49% (222/453 patients). After propensity score matching, 172 patients were included in each group (the LapA and the OpenA). Analysis demonstrated increased operative times in the OpenA [OpenA: 96.4 ± 37.2 vs LapA 88.47 ± 33 min, p = 0.035], with shorter overall length of stay in the LapA group [OpenA 13 ± 12 vs LapA 10.3 ± 11.4 days p = 0.038]. There was no statistically significant difference in mortality [OpenA 26 (15.1%) vs LapA 18 (10.5%), p = 0.258]. Focusing on morbidity, the overall rate of 30-day postoperative morbidity was significantly lower in the LapA group [OpenA 67 patients (39.0%) vs LapA 37 patients (21.5%) p = 0.002]. When stratified using the Clavien-Dindo classification, the severity of postoperative complications was statistically different only for C-D 1-2.

CONCLUSIONS

Based on the present study, we can support that laparoscopic suturing of perforated peptic ulcers, apart from being a safe technique, could provide significant advantages in terms of postoperative complications and hospital stay.

Laparoscopic Repair Modality of Perforated Peptic Ulcer: Less Is More?

Perforation, per se, presents the most serious complication of peptic ulcer disease with a mortality rate that cannot be underestimated. Surgery is the only treatment option, which can be performed laparoscopically or via conventional laparotomy. The present study aimed to compare the short-term outcomes of laparoscopy and laparotomy techniques in the surgical treatment of peptic ulcer perforation. A retrospective study design was structured to compare the perioperative and short-term postoperative outcomes of 102 patients who had undergone laparoscopic and conventional repair of the perforated peptic ulcer over a six-year interval (January 1, 2016, to December 31, 2021). Of these, 44 (43.1%) had undergone laparoscopic repair while 58 (56.9%) had surgical repair via conventional laparotomy. The operative time and length of hospital stay were comparable in both subgroups (p=0.984 and p =0.585). Nevertheless, 30-day postoperative morbidity was significantly higher in the open surgery subgroup (75.9% vs. 59.1%, p= 0.032). The risk of relaparotomy was similar in both study subgroups; however, suture dehiscence as a reason for surgical revision was significantly more frequent in the laparoscopic subgroup (13.6% vs 3.4%). Of note, the mortality rate in the laparoscopic group of patients was 13.6%, and in the laparotomy group 41.4%. The laparoscopic approach to peptic ulcer perforation is the procedure of choice for low-risk patients. Conventional surgery seems to be associated with a significantly higher incidence of severe postoperative complications and mortality. However, the higher mortality in these patients is probably related to their worse initial clinical condition.

Risk factors for leak after omentopexy for duodenal ulcer perforations

AIMS

Duodenal ulcer perforations are frequently encountered but there is limited literature regarding risk factors for leak after omentopexy.

METHODOLOGY

The record of 100 patients of duodenal ulcer perforation undergoing omentopexy by open approach was prospectively maintained to identify any significant factors contributing towards leak.

RESULTS

Out of 100 patients undergoing omentopexy, 9 (9%) developed leak; when leak occurred, the mortality was very high (44.4%). Patients who developed leak (09) were compared against those who did not (91), and it was seen that seen that duration of symptoms before surgery (> 3 days), amount of intra-abdominal contamination (> 2 L), low body mass index (BMI < 19.35 kg/m²), serum creatinine (> 1.5 mg/dl), and deranged International Normalized Ratio (INR) were found to be significant on univariate analysis; however, multivariate analysis revealed only low BMI and high creatinine to be contributory towards leak.

CONCLUSION

Leak after omentopexy carries a high morbidity and mortality. Identification of risk factors may help in optimizing patients at risk and reduce the incidence of leak and its sequelae.

Outcomes of omental patch repair in large or giant perforated peptic ulcer are comparable to gastrectomy

PURPOSE

Perforated peptic ulcer (PPU) complicates 2 to 10% of patients with peptic ulcer disease and has mortality risk of up to 20%. Omental patch repair is the mainstay of surgical management and gastric resectional procedures are advocated for a large/giant ulcer or suspected malignancy. Emergency gastrectomy is associated with increased morbidity and mortality. The aim of this study is to compare the outcomes of omental patch repair with gastrectomy in patients with large PPU (≥ 20 mm).

METHODS

A retrospective review of all PPU patients who underwent surgery from January 2008 to December 2014 was done. Patients with PPU < 20 mm were excluded. Patient demographics and perioperative data were recorded. Length of hospital stay, post-operative complications, need for intensive care unit admission and all-cause mortality are reported.

RESULTS

110 patients with a median age of 69.1 (range 28-90) years had PPU ≥ 20 mm. 42 (38.2%) patients presented within 24 h from the onset of abdominal pain. The median American Society of Anaesthesiology score was 3 (range 1-4). 52 patients had omental patch repair and 58 patients had gastrectomy. The overall incidence of intra-abdominal collection, post-operative leakage, re-operation and all-cause mortality was 16.4%, 11.8%, 6.4% and 19.1%, respectively. No difference in post-operative outcomes between the two groups was detected: intra-abdominal collection (p = 0.793), post-operative leakage (p = 0.813), re-operation (p = 0.809) and all-cause mortality (p = 0.736).

CONCLUSION

Omental patch repair confers similar perioperative outcomes as compared to gastrectomy in patients with large PPU.

New machine learning scoring system for predicting postoperative mortality in gastroduodenal ulcer perforation: A study using a Japanese nationwide inpatient database

BACKGROUND

Conventional prediction models for estimating risk of postoperative mortality in gastroduodenal ulcer perforation have suboptimal prediction ability. We aimed to develop and validate new machine learning models and an integer-based score for predicting the postoperative mortality.

METHODS

We retrospectively identified patients with gastroduodenal ulcer perforation who underwent surgical repair, using a nationwide Japanese inpatient database. In a derivation cohort from July 2010 to March 2016, we developed 2 machine learning-based models, Lasso and XGBoost, using 45 candidate predictors, and also developed an integer-based score for clinical use by including important variables in Lasso. In a validation cohort from April 2016 to March 2017, we measured the prediction performances of the models by computing area under the curve and comparing it to the conventional American Society of Anesthesiology risk score.

RESULTS

Of 25,886 patients, 1,176 (4.5%) died after surgical repair. For the validation cohort, Lasso and XGBoost had significantly higher prediction abilities than the American Society of Anesthesiology score (Lasso area under the curve = 0.84; 95% confidence interval 0.81-0.86; American Society of Anesthesiology score area under the curve = 0.70; 95% confidence interval 0.65-0.74, P < .001). The integer-based risk score, which had 13 factors, had a prediction ability similar to those of Lasso and XGBoost (area under the curve = 0.83; 95% confidence interval 0.81-0.86). According to the integer-based score, the mortalities were 0.1%, 2.3%, 9.3%, and 29.0% for the low (score, 0), moderate (1-2), high (3-4), and very high (≥5) score groups, respectively.

CONCLUSION

Machine learning models and the integer-based risk score performed well in predicting risk of postoperative mortality in gastroduodenal ulcer perforation. These models will help in decision making.

Omental plug using double horizontal mattress suture for gastric perforation on elderly patients with boey score 3: A case series

INTRODUCTION

Gastric perforation is a life-threatening condition. Patients with gastric perforation with Boey score 3 has very high mortality rate. Immediate source control is required for primary repair and preventing further complications. Furthermore, elderly patients pose a greater risk of morbidity and mortality in cases of gastric perforation, especially during and after emergency surgery.

CASE PRESENTATION

We present two cases of elderly patients with gastric perforation with Boey score 3. We performed omental plugging technique with double horizontal mattress suture type. In these cases, we decided not to perform biopsy and margin freshening of the perforation.

DISCUSSION

We performed omental plugging technique because we are confident that it could cover the perforation completely without causing gastric outlet obstruction. An emergency source control surgery can be effectively done with this omental plugging procedure. During surgery, margin freshening and biopsy is not performed to perform source control more quickly. This surgical procedure aligned with "quick in-quick out" concept that we adopted for treating patients with gastric perforation. Omental plugging also allows patient to undergo ERAS program for better and faster recovery. The patients were discharged from the hospital without further complications and long-term follow-up showed good results.

CONCLUSION

Omental plugging has the least risk of complications than other perforation repair techniques and can be done for small and large perforation. Based on our case series, omental plug with double mattress suture is an effective and safe procedure to be performed in elderly patients with gastric perforation with Boey score 3.

A Fast and Reliable Method to Interpret Short-Term Mortality in Perforated Peptic Ulcer: Red Cell Distribution Width is Sensitive and Specific

Introduction

Peptic ulcer is an important health problem worldwide with a prevalence of around 5%. Peptic ulcer perforation is a potentially mortal complication of peptic ulcer disease. We aimed to investigate the potential use of red cell distribution width as a prognostic marker in peptic ulcer perforation.

Methods

The files, operation notes, biochemical and hematological parameters, and prognosis of patients who were operated for a peptic ulcer perforation were reviewed in a retrospective cohort study. The relation of red cell distribution width (RDW) to main outcome in-hospital mortality was assessed.

Results

The mean age of the 172 patients was 40 ± 17.89. There were 158 (92%) males and 14 (8%) females. The in-hospital mortality was 8.7% (15/172). The median RDW in the group with mortality was 15.00 (interquartile range (IQR): 14.30–17.20) compared with the median RDW in the group with no mortality as 13.2 (IQR: 12.80–14.00, p ≤ 0.001). Receiver operator characteristic curves were plotted for RDW to identify nonsurvivors and yielded a significant area under the curve as 0.812 (95% confidence interval: 0.682–0.942). The sensitivity and specificity of RDW at a cutoff value of 14.25% were calculated with an accuracy of 81.98 (95% confidence interval: 75.40–87.41) as 80.00 (51.91–95.67) and 82.17 (75.27–87.81), respectively.

Conclusion

Increased RDW may be of use to interpret mortality in patients with peptic ulcer perforation.

Risk factors influencing postoperative outcome in patients with perforated peptic ulcer: a prospective cohort study

BACKGROUND

Perforated peptic ulcer (PPU) has been associated with substantially high incidence of morbidity and mortality. The aim of this study was to analyze the factors affecting the outcome of patients having perforated peptic ulcer undergoing surgical intervention.

MATERIALS AND METHODS

Medical records of 112 patients with PPU who underwent emergency laparotomy between December 2014 and November 2016 were prospectively analyzed. Primary suture of the perforation and pedicled omentoplasty was done in all the patients. Data regarding patients was collected and correlated with the postoperative outcome.

RESULTS

The overall postoperative morbidity and mortality were 62.5% and 30.4%, respectively. On univariate analysis advanced age (≥ 60 years) [(p = 0.005), (OR = 3.6), (95% CI = 1.5-8.8)], pre-operative shock [(p < 0.001), (OR = 7.4), (95% CI = 2.6-21.0)], delayed presentation (> 24 h) [(p = 0.007), (OR = 4.0), (95% CI = 1.5-11.2)] and raised serum creatinine [(p < 0.001), (OR = 7.7), (95% CI = 3.1-19.0)] were found to be significantly associated with the post-operative morbidity. For mortality, advanced age (≥ 60 year) [(p < 0.001), (OR = 5.02), (95% CI = 2.1-11.9)], pre-operative shock [(p < 0.001), (OR = 19.3), (95% CI = 6.9-53.6)], comorbidity [(p = 0.03), (OR = 6.6), (95% CI = 1.2-35.7)] and raised serum creatinine [(p < 0.001), (OR = 13.1), (95% CI = 4.5-37.8)] were statistically significant factors. Multivariate analysis showed advanced age (≥ 60 years) (p = 0.05) and raised serum creatinine (p = 0.004) as significant factors for increased risk of post-operative morbidity. Advanced age (≥ 60 years), pre-operative shock and raised serum creatinine were found to be independent risk factors influencing post-operative mortality (p < 0.05).

CONCLUSION

A thorough clinical evaluation, adequate resuscitation, sepsis control, addressing comorbidities and early access to hospital can reduce the risk morbidity and mortality in patients with PPU.

Experience sharing of conservative treatment after a 90-year-old male replacing the suprapubic bladder catheter enters the small intestine: A rare case report

Introduction

The treatment of intestinal perforation caused by the SBC enters the small intestine in elderly patients is a challenge for urologists. The report is to share our experience of conservative treatment after a 90-year-old male with the suprapubic bladder catheter enters the small intestine.

Presentation of case

Because of the device was obstructed, a 90-year-old male went to our hospital with his family and requested to replace the SBC. When the fistula tube was replaced, it entered the intestine through the intestinal injury site instead of entering the bladder. During the hospitalization, the patient was given supportive treatments and the SBC was dynamically monitored daily and it was intermittently withdrawn out during this period. After the drainage volume was less than 10 mL for three consecutive days and the intestinal fistula was healing gradually, the catheter was taken out.

Discussion

According to our experience, the common complications in the process include failure to pull out the SBC, abnormal position of the SBC, and poor drainage of the SBC. However, the drainage tube placing into the small intestine through the original hole of the suprapubic bladder fistula during the replacement process is quite rare. When elderly patients have traumatic small bowel perforation, the diagnosis and treatment of intestinal perforation in elderly patients was particularly important.

Conclusion

The conservative treatment of intestinal perforation is suitable for elderly patients who are unsuitable or unwilling to undergo a surgical operation. Of course, it should be in accordance with the patient's condition to make the right choice of treatment.

Duodenal Perforation: Outcomes after Surgical Management at a Tertiary Care Centre-A Retrospective Cross-Sectional Study

Introduction

Duodenal perforation is a common surgical emergency and carries mortality ranging from 4% to 30% reported in Western countries, but there is a paucity of reports from India. We aimed to determine the factors which influence the surgical outcomes in patients with duodenal perforation.

Methods

We retrospectively analyzed prospectively collected data from January 2010 to December 2018.

Results

A total of 55 patients were included in the study of which 69% (38) were males and 31% (17) were females (M : F = 4.5 : 2). The mean age was 52.3 years. The cause for duodenal perforation was duodenal ulcer (n = 25, 45.5%), followed by post-ERCP complications (n = 15, 27.3%), surgery (n = 11, 20%), and blunt trauma (n = 4, 7.2%) with perforations localized at D2 (n = 28, 51%) and at D1 (n = 27, 49%). Patients underwent primary repair with an additional diversion procedure (n = 28, 51%) and repair only in 18 (32.8%). There were 21 (38%) deaths. Patients with ERCP-associated duodenal perforation had longer hospital stay (P ≤ 0.001), ICU stay (P=0.049), duration of drainage (P ≤ 0.001), and higher leak rate (P=0.001) and re-exploration rate (P=0.037). A high mortality rate was seen in patients with preoperative organ failure (n  = 18, 78% versus 9.4%, P=0.001), postoperative leak (n = 7, 64% versus 32%, P=0.05), and longer duration from onset of symptoms to surgery (≥4 days) (P=0.045).

Conclusion

Perforation of the duodenum is associated with high morbidity and mortality regardless of its cause and is higher in those who have a longer interval to surgery, preoperative organ failure, and a postoperative leak.

Laparoscopic Repair of Perforated Peptic Ulcer in the Elderly: An Interim Analysis of the FRAILESEL Italian Multicenter Prospective Cohort Study

INTRODUCTION

The number of elderly patients requiring emergency surgical intervention has increased dramatically. Perforated peptic ulcer (PPU) complications, such as perforation, have remained relatively stable and associated morbidity remains between 10% and 20%. Advances in perioperative care have greatly improved the outcomes of laparoscopic emergency surgery, allowing increasing numbers of patients, even the elderly, to undergo safe repair. The aim of this study was to evaluate the feasibility, safety, and outcome of laparoscopic gastric repair in the elderly using the database of the FRAILESEL (Frailty and Emergency Surgery in the Elderly) study.

MATERIALS AND METHODS

This is a retrospective analysis carried out on data of the FRAILESEL study. Data on all the elderly patients who underwent emergency abdominal surgery for PPU from January 2017 to December 2017 at 36 Italian surgical departments were analyzed. Patients who underwent PPU repair were further divided into a laparoscopic gastroduodenal repair (LGR) cohort and an open gastroduodenal repair (OGR) cohort, and the clinicopathologic features of the patients in both the groups were compared.

RESULTS

Sixty-seven patients fulfilled the inclusion criteria. Thirty-three patients (47.8%) underwent LGR. The LGR patients had less blood loss and shorter postoperative stay, even if the difference was not statistically significant. The mean operative time was significantively higher in the OGR (OGR 96.5±27.7 vs. LGR 78.6±16.3 P=0.000). The rate of death after laparoscopic surgery was similar to the rate of the open surgery. Multivariate analysis indicated that only age (P=0.018), admission haemoblogbin (Hb) level (P=0.006), platelet count (P=0.16), lactate level (P=0.47), and Mannheim Peritonitis Index (P=0.18) were independent variables associated with the risk of overall mortality.

CONCLUSIONS

LGR is safe and feasible in elderly patients with PPU and it is associated with better perioperative outcomes. However, patient selection and preoperative frailty evaluation in the elderly population are the key to achieving better outcomes.

Primary laparoscopic approach to repair perforated peptic ulcer. A retrospective cohort study

BACKGROUND

Perforated peptic ulcer is a serious complication of peptic ulcer disease and carries high risk for morbidity and mortality. Although the incidence of peptic ulcer disease has decreased in recent decades, the percentage of patients with perforated peptic ulcer requiring emergency surgery remains constant. The use of laparoscopic management as a first choice for the treatment of the perforation is growing but is not routine in many centers.

METHODS

Clinical and surgical data on 42 patients underwent surgical treatment for perforated peptic ulcer from January 2012 to December 2016 were collected. Laparoscopic repair of the perforation with a three-port technique was made in all cases. The Boey scoring system was used to predict the prognosis.

RESULTS

All patients underwent suture-closure of the ulcer, and omental patch through laparoscopy without conversion to open surgery. Duodenal leakages occurred in 3 patients (7.1%), then treated with a conservative approach and resolved on the 10^th postoperative day. Two patients (4.7%) had deep space infections in the first week after surgery, therefore subdiaphragmatic and pelvic abscess were drained by ultrasound guidance. Four patients (9.5%) died up to 30-day post-surgery due to progression of multisystem organ failure in absence of leakages or infections. All these patients were American Society of Anesthesiologists Classification >III and Boey Score 3.

CONCLUSIONS

Our data show that a primary laparoscopic approach in patients with peptic ulcer perforation is associated with postoperative advantages and acceptable rates of morbidity and mortality, essentially related to high Boey Score. Therefore, we suggest that the surgical repair of PPU could be always started laparoscopically.

Free abdominal gas on computed tomography in the emergency department: aetiologies and association between amount of free gas and mortality

INTRODUCTION

Free abdominal gas is an important finding with major clinical implications. However, data on the aetiologies and prognosis of patients with free gas are scarce. Our primary aim was to describe the sources of free abdominal gas on emergency department (ED) computed tomography (CT). The secondary aim was to evaluate the association between the amount of free gas and all-cause mortality.

METHODS

All patients who underwent CT in the ED between February 2012 and February 2019 with free abdominal gas were included in the study. A scoring system was used to assess the amount of free gas: small - gas bubbles; medium - any gas pocket ≤2cm in diameter; large - any gas pocket >2cm. Data were collected from laboratory and clinical assessment regarding the source of free gas and all-cause mortality.

RESULTS

A total of 372 patients had free abdominal gas. Colonic diverticulitis was the most common aetiology among those with a small or medium amount of free gas (81/250 [32.4%] and 12/71 [16.9%] respectively). For patients with a large amount of gas, peptic disease was the most common aetiology (11/51 [21.6%]). Three-quarters of the patients (280/372, 75.2%) had the source of free gas identified during ED admission. Ninety-day mortality rates were 7.2%, 9.9% and 21.6% for patients with small, medium and large amounts of gas respectively (p=0.007).

CONCLUSIONS

Colonic diverticulitis was the most common source of free abdominal gas and peptic disease was the most common cause of a large amount of free gas. Mortality rates correlated with the amount of gas and were significantly higher in patients with a large amount.

Assessment of PULP score in predicting 30-day perforated duodenal ulcer morbidity, and comparison of its performance with Boey and ASA, a retrospective study

Background

/aim: Scores commonly employed to risk stratify perforated peptic ulcer patients include ASA (American Society of Anesthesiologists), Boey and peptic ulcer perforation score (PULP). However, few studies assessed and compared the accuracy indices of these three scores in predicting post PPU repair 30-day morbidity. We assessed accuracy indices of PULP, and compared them to Boey and ASA in predicting post perforated duodenal (PDU) ulcer repair 30-day morbidity.

Methods

Retrospective chart review of all PDU patients (perforated duodenal ulcers only) at the largest two hospitals in Qatar (N = 152). Data included demographic, clinical, laboratory, operative, and post repair 30-day morbidity. Area under the Curve (AUC), sensitivity and specificity were computed for each of the 3 scores. Multivariate logistic regression assessed the accuracy indices of each score.

Results

All patients were males (M age 37.41 years). Post PDU repair 30-day morbidity was 10.5% (16 morbidities). Older age, higher ASA (≥3), Boey (≥1) or PULP (≥8) scores, shock on admission and preoperative comorbidities; and conversely, lower hemoglobin and albumin were all positively significantly associated with higher post PDU 30-day morbidity. PULP displayed the largest AUC (72%), and was the only score to significantly predict 30-day morbidity. The current study is the first to report the sensitivity and specificity of these three scores for post PDU repair 30-day morbidity; and first to assess accuracy indices for PULP in predicting post PDU repair 30-day morbidity.

Conclusion

PULP score had the largest AUC and was the only score to significantly predict post PDU repair 30-day morbidity.

•

The current study is the first to report the sensitivity and specificity of the three scoring systems (ASA, Boey and PULP) for post perforated duodenal ulcer repair 30-day morbidity.

•

It is also the first study to assess accuracy indices for PULP in predicting post perforated duodenal ulcer repair 30-day morbidity.

•

Compared with ASA and Boey, PULP score had the largest area under the curve and was the only score to significantly predict post perforated duodenal ulcer repair 30-day morbidity.

Laparoscopic versus open repair of perforated peptic ulcer: A retrospective cohort study

INTRODUCTION

Perforated peptic ulcer disease (PPU) is a condition subject to wide geographical variations in incidence. It remains a significant cause of morbidity and mortality, even in the era of Helicobacter pylori eradication and proton-pump inhibitor therapy. There is no clear consensus on whether laparoscopic or open approaches are superior, and with most studies in this area originating from Europe and Asia, Australian data addressing this issue are lacking.

METHODS

This retrospective cohort study included all patients who underwent surgery for PPU within a hospital network in Australia. Baseline variables and primary outcomes, including length of hospital stay, chest and abdominal complications, and mortality, were recorded. Secondary outcomes, including reasons for conversion, were also considered.

RESULTS

In total, 109 patients underwent operations for PPU between January 2011 and December 2015. There were no significant differences with regard to baseline comorbidities. There were no statistically significant differences in terms of median length of hospital stay or rates of chest and abdominal complications, but the operative time was 28.5 min longer (P = <0.001) in the laparoscopic group than in the open group.

CONCLUSION

Open operations were faster to perform than laparoscopic operations for repair of PPU. Despite increased experience treating many surgical diseases laparoscopically, this study did not find it to be superior in terms of length of hospital stay or complication rates.

Laparoscopic Repair for Perforated Peptic Ulcer Disease Has Better Outcomes Than Open Repair

PURPOSE

Over the last 3 decades, laparoscopic procedures have emerged as the standard treatment for many elective and emergency surgical conditions. Despite the increased use of laparoscopic surgery, the role of laparoscopic repair for perforated peptic ulcer remains controversial among general surgeons. The aim of this study was to compare the outcomes of laparoscopic versus open repair for perforated peptic ulcer.

METHODS

A systemic literature review was conducted using Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. A search was conducted using MEDLINE, EMBASE, PubMed and Cochrane Database of all randomised controlled trials (RCT) that compared laparoscopic (LR) with open repair (OR) for perforated peptic ulcer (PPU). Data was extracted using a standardised form and subsequently analysed.

RESULTS

The meta-analysis using data from 7 RCT showed that LR for PPU has decreased overall post-operative morbidity (LR = 8.9% vs. OR = 17.0%) (OR = 0.54, 95% CI 0.37 to 0.79, p < 0.01), wound infections, (LR = 2.2% vs. OR = 6.3%) (OR = 0.3, 95% CI 0.16 to 0.5, p < 0.01) and shorter duration of hospital stay (6.6 days vs. 8.2 days, p = 0.01). There were no significant differences in length of operation, leakage rate, incidence of intra-abdominal abscess, post-operative sepsis, respiratory complications, re-operation rate or mortality. There was no publication bias and the quality of the studies ranged from poor to good.

CONCLUSION

These results demonstrate that laparoscopic repair for perforated peptic ulcer has a reduced morbidity and total hospital stay compared with open approach. There are no significant differences in mortality, post-operative sepsis, abscess and re-operation rates. LR should be the preferred treatment option for patients with perforated peptic ulcer disease.

Laparoscopic and open repair for perforated duodenal ulcer: single-center experience

Introduction

Perforation is a dangerous complication of peptic ulcer disease and requires emergency surgical treatment. In recent decades laparoscopic repair of duodenal perforation has been widely used in emergency abdominal surgery.

Aim

To analyze laparoscopic and open surgical treatment of 120 consecutive patients with perforated duodenal ulcer.

Material and methods

The study included a group of 120 consecutive patients, operated on for perforated duodenal ulcer in a single institution. Laparoscopic or open repair with or without an omental patch was performed. The value of the Boey score was investigated in predicting the outcomes of treatment in the entire study group.

Results

In 61 (50.8%) cases open repair was performed, in 56 (46.7%) cases laparoscopic repair, and in 3 (2.5%) cases conversion was performed. In the laparoscopy group the mean hospital stay was 5 days (range: 3–14), in the open group 11.7 days (range: 6–63), and in the conversion group 9.3 days (8–10) (p < 0.001). There was a significant difference between characteristics of patients in the laparoscopic groups: in the second period of laparoscopic procedures (2014–2017) the duration of the operation was significantly shorter and the number of postoperative complications was significantly lower than in the initial study group (2010–2013).

Conclusions

The laparoscopic approach is an effective method for treatment of perforated duodenal ulcer in selected cases. A number of 20–25 cases for the surgeon operating with the laparoscopic method is sufficient to achieve an acceptable level of expertise. More prospective randomized studies are needed to evaluate the effectiveness of laparoscopic repair of perforated duodenal ulcer.

Surgical repair of perforated peptic ulcers: laparoscopic versus open approach

INTRODUCTION

Perforated peptic ulcers are a surgical emergency that can be repaired using either laparoscopic surgery (LS) or open surgery (OS). No consensus has been reached on the comparative outcomes and safety of each approach.

METHODS

Using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database, we conducted a 12-year retrospective review (2005-2016) and identified 6260 adult patients who underwent either LS (n = 616) or OS (n = 5644) to repair perforated peptic ulcers. To mitigate selection bias and adjust for the inherent heterogeneity between groups, we used propensity-score matching with a case (LS):control (OS) ratio of 1:3. We then compared intraoperative outcomes such as operative time, and 30-day postoperative outcomes including infectious and non-infectious complications, and mortality.

RESULTS

Propensity-score matching created a total of 2462 matched pairs (616 in the LS group, 1846 in the OS group). Univariate analysis demonstrated successful matching of patient characteristics and baseline clinical variables. We found that OS was associated with a shorter operative time (67.0 ± 28.6 min, OS versus 86.9 ± 57.5 min, LS; P < 0.001) but a longer hospital stay (8.6 ± 6.2 days, OS versus 7.8 ± 5.9 days, LS; P = 0.001). LS was associated with a lower rate of superficial surgical site infections (1.5%, LS versus 4.2%, OS; P = 0.032), wound dehiscence (0.3%, LS versus 1.6%, OS; P = 0.030), and mortality (3.2%, LS versus 5.4%, OS; P = 0.009).

CONCLUSION

Fewer than 10% of patients with perforated peptic ulcers underwent LS, which was associated with reduced length of stay, lower rate of superficial surgical site infections, wound dehiscence, and mortality. Given our results, a greater emphasis should be provided to a minimally invasive approach for the surgical repair of perforated peptic ulcers.

Patients With Perforated Peptic Ulcers: Risk Factors for Morbidity and Mortality

Perforated peptic ulcers continue to be an important problem in surgical practice. In this study, risk factors for peptic ulcer perforation-associated mortality and morbidity were evaluated. This is a retrospective study of patients surgically treated for perforated peptic ulcer over a decade (March 1999–December 2014). Patient age, sex, complaints at presentation, time lapse between onset of complaints and presentation to the hospital, physical findings, comorbidities, laboratory and imaging findings, length of hospitalization, morbidity, and mortality were recorded. The Mannheim peritonitis index (MPI) and Acute Physiology and Chronic Health Evaluation (APACHE) II score were calculated and recorded for each patient on admission to the hospital. Of the 149 patients, mean age was 50.6 ± 19 years (range: 17–86). Of these, 129 (86.5%) were males and 20 (13.4%) females. At least 1 comorbidity was found in 42 (28.1%) of the patients. Complications developed in 36 (24.1%) of the patients during the postoperative period. The most frequent complication was wound site infection. There was mortality in 26 (17.4%) patients and the most frequent cause of mortality was sepsis. Variables that were found to have statistically significant effects on morbidity included age older than 60 years, presence of comorbidities, and MPI (P = 0.029, 0.013, and 0.013, respectively). In a multivariate analysis, age older than 60 years, presence of comorbidities, and MPI were independent risk factors that affected morbidity. In the multivariate logistic regression analysis, age older than 60 years [P = 0.006, odds ratio (OR) = 5.99, confidence interval (CI) = 0.95] and comorbidities (OR = 2.73, CI = 0.95) were independent risk factors that affected morbidity. MPI and APACHE II scoring were both predictive of mortality. Age older than 60, presentation time, and MPI were independent risk factors for mortality. Undelayed diagnosis and appropriate treatment are of the utmost importance when presenting with a perforated peptic ulcer. We believe close observation of high-risk patients during the postoperative period may decrease morbidity and mortality rates.

Laparoscopy is an available alternative to open surgery in the treatment of perforated peptic ulcers: a retrospective multicenter study

Background

Perforated peptic ulcers (PPU) remain one of the most frequent causes of death. Their incidence are largely unchanged accounting for 2–4% of peptic ulcers and remain the second most frequent abdominal cause of perforation and of indication for gastric emergency surgery. The minimally invasive approach has been proposed to treat PPU however some concerns on the offered advantages remain.

Methods

Data on 184 consecutive patients undergoing surgery for PPU were collected. Likewise, perioperative data including shock at admission and interval between admission and surgery to evaluate the Boey’s score.

It was recorded the laparoscopic or open treatments, the type of surgical procedure, the length of the operation, the intensive care needed, and the length of hospital stay.

Post-operative morbidity and mortality relation with patient’s age, surgical technique and Boey’s score were evaluated.

Results

The relationship between laparoscopic or open treatment and the Boey’s score was statistically significant (p = 0.000) being the open technique used for the low-mid group in 41.1% and high score group in 100% and laparoscopy in 58.6% and 0%, respectively. Postoperative complications occurred in 9.7% of patients which were related to the patients’ Boey’s score, 4.7% in the low-mid score group and 21.4% in the high risk score group (p = 0.000). In contrast morbidity was not related to the chosen technique being 12.8% in open technique and 5.3% in laparoscopic one (p = 0.092, p > 0.05).

30-day post-operative mortality was 3.8% and occurred in the 0.8% of low-mid Boey’s score group and in the 10.7% of the high Boey’s score group (p = 0.001). In respect to the surgical technique it occurred in 6.4% of open procedures and in any case in the Lap one (p = 0.043). Finally, there was a statistically significant difference in morbidity and mortality between patients < 70 and > 70 years old (p = 0.000; p = 0.002).

Conclusions

Laparoscopy tends to be an alternative method to open surgery in the treatment of perforated peptic ulcer. Morbidity and mortality were essentially related to Boey’s score. In our series laparoscopy was not used in high risk Boey’s score patients and it will be interesting to evaluate its usefulness in high risk patients in large randomized controlled trials.

[Perforated duodenal ulcer in high risk patients]

AIM

To improve the outcomes in patients with perforated duodenal ulcers.

MATERIAL AND METHODS

Cohort study included 456 patients with perforated duodenal ulcer. High risk of mortality was determined in 9% of patients (n=40) considering Boey diagnostic criteria (1982, 1987). There were 19 women and 21 men aged 59±2.8 years.

RESULTS

Perforated duodenal ulcer was followed by overall mortality near 3.8%. In high risk group this value was 17.5% (7 out of 40 patients) while expected mortality was 45.5-100% in these patients in view of Boey criteria. The main causes of death were multiple organ failure, pulmonary embolism and acute myocardial infarction.

CONCLUSION

Minimally invasive surgery including step-by-step procedures (mini-laparotomy, laparoscopy and navigation) are the key to improve the outcomes in patients with perforated duodenal ulcer.

Is it possible to reduce the surgical mortality and morbidity of peptic ulcer perforations?

Objective

Peptic ulcer perforation is a life-threatening situation requiring urgent surgical treatment. A novel vision in peptic ulcer perforation is necessary to fill the gaps created by antiulcer medication, aging of the patients, and presentation of resistant cases in our era. In this study, we aimed to share our findings regarding the effects of various risk factors and operative techniques on the mortality and morbidity of patients with peptic ulcer perforation.

Material and Methods

Data from 112 patients presenting at our Training and Research Hospital Emergency Surgery Department between January 2010 and December 2015 who were diagnosed with PUP through physical examination and laboratory and radiological tests and operated at the hospital have been retrospectively analyzed. Patients were divided into three groups based on morbidity (Group 1), mortality (Group 2), and no complication (Group 3).

Results

Of the 112 patients included in the study, morbidity was observed in 21 (18.8%), mortality in 11 (9.8%), and no complication was observed in 80 (71.4%), who were discharged with cure. The differences between group for the average values of the perforation diameter and American Society of Anesthesiologists, Acute Physiology and Chronic Health Evaluation II, and Mannheim Peritonitis Index scores were statistically significant (p<0.001 for each). The average values for the group with mortality were significantly higher than those of the other groups.

Conclusion

In this study where we investigated risk factors for increased morbidity and mortality in PUPs, there was statistically significant difference between the average values for age, body mass index, perforation diameter, and Acute Physiology and Chronic Health Evaluation II and Mannheim Peritonitis Index scores among the three groups, whereas the amount of subdiaphragmatic free air did not differ.

Prognostic factors in peptic ulcer perforations: a retrospective 14-year study

Regarding the complications of peptic ulcer, a perforation remains the most important fatal complication. The aim of our retrospective study was to determine relations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. In total, 239 patients who underwent emergency surgery for perforated peptic ulcer in Ege University General Surgery Department, between June 1999 and May 2013 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. One hundred seventy-five of the 239 patients were male (73.2%) and 64 were female (26.8%). Mean American Society of Anesthesiologists (ASA) score was 1 in the patients without morbidity, but mean ASA score was 3 in the morbidity and mortality groups. Primary suture and omentoplasty was the selected procedure in 228 of the patients. Eleven patients underwent resection. In total, 105 patients (43.9%) had comorbidities. Thirty-seven patients (67.3%) in the morbidity group had comorbid diseases. Thirteen (92.9%) patients in the mortality group had comorbid diseases. Perforation as a complication of peptic ulcer disease still remains among the frequent indications of urgent abdominal surgery. Among the analyzed parameters, age, ASA score, and having comorbid disease were found to have an effect on both mortality and morbidity. The controversial subject in the present study is regarding the duration of symptoms. The duration of symptoms had no effect on mortality nor morbidity in our study.

Outcome of nonsurgical intervention in patients with perforated peptic ulcers

BACKGROUND

Although surgical intervention is the favorable treatment modality for perforated peptic ulcer, nonsurgical treatment is another option. The aim of this study is to analyze the results of conservative treatment for perforated peptic ulcer.

METHODS

Between 2003 and 2014, 403 patients were admitted to our hospital for perforated peptic ulcer, and 383 patients underwent surgery, whereas 20 were allocated to conservative treatment. The results of nonsurgical intervention in these patients were analyzed retrospectively.

RESULTS

The overall mortality rate of conservative treatment was 40%. Eleven patients remained hospitalized less than 2 weeks; among them, patients with a high (≥IV) American Society of Anesthesiologists class at admission had higher mortality than those with a low (<IV) American Society of Anesthesiologists class (83.3% vs 0%, P=.015). However, when patients remained hospitalized longer than 2 weeks, the mortality rates did not differ between patients with the low and high American Society of Anesthesiologists classes. Eight patients presented with a high American Society of Anesthesiologists class, of which 3 received early enteral feeding, and all of them survived. In contrast, the survival of patients without early enteral feeding was 0%, suggesting that early enteral feeding improved survival of patients with the high American Society of Anesthesiologists class (P=.018).

CONCLUSIONS

A higher American Society of Anesthesiologists class correlated with mortality in patients undergoing conservative treatment during the first 2 weeks of hospitalization. Early enteral feeding might improve the outcome of conservative treatment in patients with high American Society of Anesthesiologists class.

Which cause of diffuse peritonitis is the deadliest in the tropics? A retrospective analysis of 305 cases from the South-West Region of Cameroon

Background

Acute diffuse peritonitis is a common surgical emergency worldwide and a major contributor to non-trauma related death toll. Its causes vary widely and are correlated with mortality. Community acquired peritonitis seems to play a major role and is frequently related to hollow viscus perforation. Data on the outcome of peritonitis in the tropics are scarce. The aim of this study is to analyze the impact of tropic latitude causes of diffuse peritonitis on morbidity and mortality.

Methods

We retrospectively reviewed the records of 305 patients operated on for a diffuse peritonitis in two regional hospitals in the South-West Region of Cameroon over a 7 years period. The contributions of various causes of peritonitis to morbidity and mortality were analyzed.

Results

The diagnosis of diffuse peritonitis was suggested on clinical ground only in more than 93 % of cases. The most common causes of diffuse peritonitis included peptic ulcer perforation (n = 69), complications of acute appendicitis (n = 53) and spontaneous perforations of the terminal ileum (n = 43). A total of 142 complications were recorded in 96 patients (31.5 % complication rate). The most common complications included wound dehiscence, sepsis, prolonged paralytic ileus and multi-organ failure. Patients with typhoid perforation of the terminal ileum carried a significantly higher risk of developing a complication (p = 0.002). The overall mortality rate was 15.1 %. The most common cause of death was septic shock. Differential analysis of mortality of various causes of peritonitis indicated that the highest contributors to death toll were typhoid perforation of terminal ileum (34.7 % of deaths), post-operative peritonitis (19.5 %) and peptic ulcer perforation (15.2 %).

Conclusion

The diagnosis of diffuse peritonitis can still rely on clinical assessment alone in the absence of sophisticated imaging tools. Peptic ulcer and typhoid perforations are still major contributors to death toll. Patients presenting with these conditions require specific attention and prevention policies must be reinforced.

Risk assessment tools validated for patients undergoing emergency laparotomy: a systematic review

Emergency laparotomies are performed commonly throughout the world, but one in six patients die within a month of surgery. Current international initiatives to reduce the considerable associated morbidity and mortality are founded upon delivering individualised perioperative care. However, while the identification of high-risk patients requires the routine assessment of individual risk, no method of doing so has been demonstrated to be practical and reliable across the commonly encountered spectrum of presentations, co-morbidities and operative procedures. A systematic review of Embase and Medline identified 20 validation studies assessing 25 risk assessment tools in patients undergoing emergency laparotomy. The most frequently studied general tools were APACHE II, ASA-PS and P-POSSUM. Comparative, quantitative analysis of tool performance was not feasible due to the heterogeneity of study design, poor reporting and infrequent within-study statistical comparison of tool performance. Reporting of calibration was notably absent in many prognostic tool validation studies. APACHE II demonstrated the most consistent discrimination of individual outcome across a variety of patient groups undergoing emergency laparotomy when used either preoperatively or postoperatively (area under the curve 0.76-0.98). While APACHE systems were designed for use in critical care, the ability of APACHE II to generate individual risk estimates from objective, exclusively preoperative data items may lead to better-informed shared decisions, triage and perioperative management of patients undergoing emergency laparotomy. Future endeavours should include the recalibration of APACHE II and P-POSSUM in contemporary cohorts, modifications to enable prediction of morbidity and assessment of the impact of adoption of these tools on clinical practice and patient outcomes.

The relationship between computed tomography findings and the locations of perforated peptic ulcers: it may provide better information for gastrointestinal surgeons

BACKGROUND

Computed tomography (CT) plays an important role in diagnosing gastrointestinal perforation. This study explored the relationship between CT findings and the locations of perforated peptic ulcers (PPUs), which may help further surgical planning.

METHODS

During a 34-month period, 175 patients had CT scans. We categorized those 175 patients into 2 groups: patients with and without a PPU at a difficult ulcer site for a laparoscopic approach. Both clinical data and the CT images were reviewed and analyzed.

RESULTS

Based on the univariate analysis results, we conducted multivariate analyses of 3 factors: age, American Society of Anesthesiologists classification of 3 or more, and positive lesser sac image findings. The positive lesser sac findings in CT were the only independent factor that was correlated to the PPU site.

CONCLUSIONS

Positive lesser sac CT findings may help to predict PPUs in sites where a laparoscopic approach might be difficult. Our study re-evaluates the additional value of CT scanning in diagnosing PPU, and the results may assist with surgical planning in clinical practice.

A practical scoring system to predict mortality in patients with perforated peptic ulcer

Introduction

The mortality rate of perforated peptic ulcer is still high particularly for aged patients and all the existing scoring systems to predict mortality are complicated or based on history taking which is not always reliable for elderly patients. This study’s aim was to develop an easy and applicable scoring system to predict mortality based on hospital admission data.

Methods

Total 227 patients operated for perforated peptic ulcer in two centers were included. All data that may be potential predictors with respect to hospital mortality were retrospectively analyzed.

Results

The mortality and morbidity rates were 10.1% and 24.2%, respectively. Multivariated analysis pointed out three parameters corresponding 1 point for each which were age >65 years, albumin ≤1,5 g/dl and BUN >45 mg/dl. Its prediction rate was high with 0,931 (95% CI, 0,890 to 0,961) value of AUC. The hospital mortality rates for none, one, two and three positive results were zero, 7.1%, 34.4% and 88.9%, respectively.

Conclusion

Because the new system consists only age and routinely measured two simple laboratory tests (albumin and BUN), its application is easy and prediction power is satisfactory. Verification of this new scoring system is required by large scale multicenter studies.

Risk factors associated with conversion of laparoscopic simple closure in perforated duodenal ulcer

BACKGROUND

Precise patient selection criteria are necessary to guide the surgeon in selecting laparoscopic repair for patients with perforated peptic ulcers. The aims of this study are to report surgical outcomes after surgery for perforated duodenal ulcers and identify risk factors for predicting failure of laparoscopic simple closure for perforated duodenal ulcer.

METHODS

In total, 77 patients who underwent laparoscopic simple closure for perforated duodenal ulcers from January 2007 to September 2013 were retrospectively analyzed. Patients were divided into totally laparoscopic and conversion groups. The characteristics of patients, intraoperative findings, postoperative complications, conversion rates and suture leakage rates of each group were investigated.

RESULTS

Laparoscopic repair was completed in 69 (89.6%) of 77 patients, while 8 (10.4%) underwent conversion to open repair. Patients in the conversion group had longer perforation time, larger perforation size, more suture leakage, longer hospital stay, and higher 30-day mortality rate than those in the totally laparoscopic group. The size of perforation was the only risk factor for conversion in multivariable analysis. Patients with an ulcer perforation size of ≥9 mm or with perforation duration of ≥12.5 h had a significantly increased risk for conversion and suture leakage.

CONCLUSIONS

Ulcer size of ≥9 mm is a significant risk factor for predicting conversion in laparoscopic simple closure. Suture leakage is associated with ulcer size (9 mm) and duration of perforation (12.5 h).

Laparoscopic Surgery in Luminal Gastrointestinal Emergencies-a Review of Current Status

Laparoscopy has already established itself as the preferred surgical approach in a variety of elective surgical conditions. Along with its usual advantages of less tissue trauma and faster recovery, its diagnostic as well as therapeutic role is making it an attractive option in emergency surgery. In this paper, we have reviewed the current status of laparoscopic surgery in luminal gastrointestinal emergencies. Relevant papers were selected using Medline database from 2007 to the present. These were reviewed, and outcomes were stated under the headings of appendicitis, perforated peptic ulcer, colorectal emergencies and small bowel obstruction. The laparoscopic intervention was found to be of clear benefit in most of the patients with appendicitis. Its role, however, is not absolutely clear in managing perforated peptic ulcers. Laparoscopic lavage and drainage have been recommended in diverticular perforation with limited contamination. Small case series and studies have shown benefits of laparoscopic surgery in iatrogenic colonic perforations, colonic obstruction, emergency colectomy and small bowel obstruction. Laparoscopic surgery can be recommended in appendicitis and low-risk cases of perforated peptic ulcers. Its definitive role in other conditions needs more evidence. The surgeon's experience and careful patient selection are very important to improve the outcome.

Conversion of laparoscopic surgery for perforated peptic ulcer: a single-center study

PURPOSE

A perforated peptic ulcer can be managed laparoscopically in selected patients. The purpose of this study was to evaluate whether conversion of emergency laparoscopy is inferior to primary median laparotomy in terms of postoperative morbidity and mortality.

METHODS

We analyzed patients who underwent laparoscopic or open surgery for a perforated peptic ulcer at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck between January, 1996 and December, 2010. Perforations were graded according to the Boey classification, a preoperative risk-scoring system.

RESULTS

Conversion to laparotomy was necessary in 20 of the 45 patients who underwent laparoscopic surgery (CG); therefore, laparoscopic operations were completed in 25 patients (LG). The third patient cohort comprised 139 patients who underwent primary laparotomy (OG). Overall minor morbidity was significantly lower (p = 0.048) in the LG patients than in the OG patients, whereas no significant differences were found in major morbidity and mortality, particularly between the OG and CG.

CONCLUSION

Patients' suitability for laparoscopic management should be decided on according to Boey's clinical scoring system. Our findings demonstrated that conversion from laparoscopy to laparotomy was not associated with elevated postoperative morbidity or mortality versus initial laparotomy. Therefore, emergency operations may be commenced laparoscopically in selected patients, especially considering the postoperative advantages of this approach.

Five year experience in management of perforated peptic ulcer and validation of common mortality risk prediction models - are existing models sufficient? A retrospective cohort study

BACKGROUND

Emergency surgery for perforated peptic ulcer (PPU) is associated with significant morbidity and mortality. Accurate and early risk stratification is important. The primary aim of this study is to validate the various existing MRPMs and secondary aim is to audit our experience of managing PPU.

METHODS

332 patients who underwent emergency surgery for PPU at a single intuition from January 2008 to December 2012 were studied. Clinical and operative details were collected. Four MRPMs: American Society of Anesthesiology (ASA) score, Boey's score, Mannheim peritonitis index (MPI) and Peptic ulcer perforation (PULP) score were validated.

RESULTS

Median age was 54.7 years (range 17-109 years) with male predominance (82.5%). 61.7% presented within 24 h of onset of abdominal pain. Median length of stay was 7 days (range 2-137 days). Intra-abdominal collection, leakage, re-operation and 30-day mortality rates were 8.1%, 2.1%, 1.2% and 7.2% respectively. All the four MRPMs predicted intra-abdominal collection and mortality; however, only MPI predicted leak (p = 0.01) and re-operation (p = 0.02) rates. The area under curve for predicting mortality was 75%, 72%, 77.2% and 75% for ASA score, Boey's score, MPI and PULP score respectively.

DISCUSSION AND CONCLUSION

Emergency surgery for PPU has low morbidity and mortality in our experience. MPI is the only scoring system which predicts all - intra-abdominal collection, leak, reoperation and mortality. All four MRPMs had a similar and fair accuracy to predict mortality, however due to geographic and demographic diversity and inherent weaknesses of exiting MRPMs, quest for development of an ideal model should continue.

Laparoscopic repair of perforated peptic ulcers: the sutured omental patch and focused sequential lavage technique

We propose a standardized technique of repair and lavage with the outcomes of 50 consecutive patients treated at our institution. The perforation was closed primarily and reinforced with omental patch. It was then followed by peritoneal lavage in a focused sequential manner that involved quadrant to quadrant lavage with tilting of operating table and changing of position between the surgeon and the camera surgeon. None of our patients had postoperative intra-abdominal complications, but unfortunately 1 patient succumbed to respiratory complications. Respiratory complications was the most common postoperative complication in our series (9 patients), whereas 2 patients had ileus. There were no leaks or reoperations in our series. Laparoscopic repair and sutured omentoplasty, followed by focused sequential lavage in a systematic manner, if performed diligently, will yield good outcomes.

Risk factors influencing morbidity and mortality in perforated peptic ulcer disease

OBJECTIVE

Peptic ulcer perforation continues to be a major surgical problem. In this study, risk factors that influence morbidity and mortality in perforated peptic ulcer disease were examined.

MATERIAL AND METHODS

Files of 148 patients who were included in the study due to peptic ulcer perforation between January 2006 and December 2010 were retrospectively analyzed. Data regarding age, gender, complaints, time elapsed between onset of symptoms and hospital admission, physical examination findings, co-morbid diseases, laboratory and imaging findings, length of hospital stay, morbidity and mortality were recorded.

RESULTS

The study group included 129 (87.2%) male and 19 (12.8%) female patients. The mean age was 51.7±20 (15-88) years. Forty five patients (30.4%) had at least one co-morbid disease. In the postoperative period, 30 patients (20.3%) had complications. The most common complication was wound infection. Mortality was observed in 27 patients (18.2%). The most common cause of mortality was sepsis. Multivariate analysis revealed age over 60 years, presence of co-morbidities and Mannheim peritonitis index as independent risk factors for morbidity. Age over 60 years, time to admission and Mannheim peritonitis index were detected as independent risk factors for mortality.

CONCLUSION

Early diagnosis and proper treatment are important in patients presenting with peptic ulcer perforation.
