New machine learning scoring system for predicting postoperative mortality in gastroduodenal ulcer perforation: A study using a Japanese nationwide inpatient database. Surgery 2021; 171:1036-1042. [PMID: 34538648 DOI: 10.1016/j.surg.2021.08.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 08/14/2021] [Accepted: 08/19/2021] [Indexed: 12/12/2022]
Abstract
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.

Abstract
Introduction In 2013, peptic ulcer disease (PUD) caused over 300 000 deaths globally. Low-income and middle-income countries are disproportionately affected. However, there is limited information regarding risk factors of perioperative mortality rates in these countries. Objective To assess perioperative mortality rates from complicated PUD in Africa and associated risk factors. Design We performed a systematic review and a random-effect meta-analysis of literature describing surgical management of complicated PUD in Africa. We used subgroup analysis and meta-regression analyses to investigate sources of variations in the mortality rates and to assess the risk factors contributing to mortality. Results From 95 published reports, 10 037 patients underwent surgery for complicated PUD. The majority of the ulcers (78%) were duodenal, followed by gastric (14%). Forty-one per cent of operations were for perforation, 22% for obstruction and 9% for bleeding. The operations consisted of vagotomy (38%), primary repair (34%), resection and reconstruction (12%), and drainage procedures (6%). The overall PUD mortality rate was 6.6% (95% CI 5.4% to 8.1%). It increased to 9.7% (95% CI 7.1 to 13.0) when we limited the analysis to studies published after the year 2000. The correlation was higher between perforated PUD and mortality rates (r=0.41, p<0.0001) than for bleeding PUD and mortality rates (r=0.32, p=0.001). Non-significant differences in mortality rates existed between sub-Saharan Africa (SSA) and North Africa and within SSA. Conclusion Perioperative mortality rates from complicated PUD in Africa are substantially high and could be increasing over time, and there are possible regional differences.

Laparoscopy is an available alternative to open surgery in the treatment of perforated peptic ulcers: a retrospective multicenter study. BMC Surg 2018; 18:78. [PMID: 30253756 PMCID: PMC6156951 DOI: 10.1186/s12893-018-0413-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Accepted: 09/17/2018] [Indexed: 02/07/2023] Open
Abstract
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.

Abstract
Laparoscopic repair of duodenal ulcer perforation has certain advantages over open repair. However, the conversion rate to open surgery is still high. The most common reason for conversion is inadequate localization of the ulcer perforation site during laparoscopy. Here, a technique is described which will aid in localizing the perforation, make suturing and repair easier, and helps in checking the integrity of the repair at the end of the procedure. This is done by compressing the gall bladder with an instrument like a laparoscopic fan retractor and simultaneously depressing the first part of the duodenum with another instrument. This results in bile flowing out through the perforation and simultaneously depressing the duodenum downward, making it more easily visible and making identification easier. Suturing is easier due to the liver also getting retracted simultaneously and more space being available consequently. Integrity of the anastomoses is also easily ascertained by this maneuver.

Abstract
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.

Abstract
BACKGROUND Perforated peptic ulcer is a common abdominal disease that is treated by surgery. The development of laparoscopic surgery has changed the way to treat such abdominal surgical emergencies. The results of some clinical trials suggest that laparoscopic surgery could be a better strategy than open surgery in the correction of perforated peptic ulcer but the evidence is not strongly in favour for or against this intervention. OBJECTIVES To measure the effect of laparoscopic surgical treatment versus open surgical treatment in patients with a diagnosis of perforated peptic ulcer in relation to abdominal septic complications, surgical wound infection, extra-abdominal complications, hospital length of stay and direct costs. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (2004, Issue 2), PubMed/MEDLINE (1966 to July 2004), EMBASE (1985 to November 2004) and LILACS (1988 to November 2004) as well as the reference lists of relevant articles. Searches in all databases were updated in December 2009 and January 2012. We did not confine our search to English language publications. SELECTION CRITERIA Randomized clinical trials comparing laparoscopic surgery versus open surgery for the repair of perforated peptic ulcer using any mechanical method of closure (suture, omental patch or fibrin sealant). DATA COLLECTION AND ANALYSIS Primary outcome measures included proportion of septic and other abdominal complications (surgical site infection, suture leakage, intra-abdominal abscess, postoperative ileus) and extra-abdominal complications (pulmonary). Secondary outcomes included mortality, time to return to normal diet, time of nasogastric aspiration, hospital length-of-stay and costs. Outcomes were summarized by reporting odds ratios (ORs) and 95% confidence intervals (CIs), using the fixed-effect model. MAIN RESULTS We included three randomized clinical trials of acceptable quality. We found no statistically significant differences between laparoscopic and open surgery in the proportion of abdominal septic complications (OR 0.66; 95% CI 0.30 to 1.47), pulmonary complications (OR 0.43; 95% CI 0.17 to 1.12) or number of septic abdominal complications (OR 0.60; 95% CI 0.32 to 1.15). Heterogeneity was significant for pulmonary complications and operating time. AUTHORS' CONCLUSIONS This review suggests that a decrease in septic abdominal complications may exist when laparoscopic surgery is used to correct perforated peptic ulcer. However, it is necessary to perform more randomized controlled trials with a greater number of patients to confirm such an assumption, guaranteeing a long learning curve for participating surgeons. With the information provided it could be said that laparoscopic surgery results are not clinically different from those of open surgery.

Abstract
BACKGROUND Morbidity and mortality rates in patients with perforated peptic ulcer (PPU) remain substantial. The aim of the present study was to evaluate the effect of a multimodal and multidisciplinary perioperative care protocol on mortality in patients with PPU. METHODS This was an externally controlled multicentre trial set in seven gastrointestinal departments in Denmark. Consecutive patients who underwent surgery for gastric or duodenal PPU between 1 January 2008 and 31 December 2009 were treated according to a multimodal and multidisciplinary evidence-based perioperative care protocol. The 30-day mortality rate in this group was compared with rates in historical and concurrent national controls. RESULTS The 30-day mortality rate following PPU was 17·1 per cent in the intervention group, compared with 27·0 per cent in the three control groups (P = 0·005). This corresponded to a relative risk of 0·63 (95 per cent confidence interval 0·41 to 0·97), a relative risk reduction of 37 (5 to 58) per cent and a number needed to treat of 10 (6 to 38). CONCLUSION The 30-day mortality rate in patients with PPU was reduced by more than one-third after the implementation of a multimodal and multidisciplinary perioperative care protocol, compared with conventional treatment.

Abstract
BACKGROUND No studies focus on the population with perforated peptic ulcer in southeastern Taiwan. The present study aimed to assess the differences between the different races and the risk factors related to mortality and morbidity in postoperative patients in southeastern Taiwan. METHODS The medical records of 237 patients were reviewed retrospectively. The following factors were analyzed: patient profiles, coexisting illnesses, diagnostic method, fever, preoperative shock, clinical data at emergency room, delay operation, site of perforation, operative method, positive ascites culture, species of microbes in ascites culture, postoperative complications, death and the length of hospital stay. RESULTS Aborigines were significantly different from non-aborigines in the ratio of female cases and in the habits of alcohol drinking and betel nut chewing. There were also four significantly different variables between them: fever, hemoglobin value, site of perforation and operative method. Total postoperative complication rate was 41.3% and 39 patients (16.6%) died. In multivariate analysis, age > or = 65 years, lipase > upper normal limit and preoperative shock were independent predictors of mortality. Significant risk factors associated with morbidity were NSAIDs use, creatinine > 1.5 mg/dL and preoperative shock. CONCLUSION Aborigines were different from non-aborigines in several categories. In southeastern Taiwan, NSAIDs use, creatinine > 1.5 mg/dL and preoperative shock were independent risk factors of morbidity, and age > or = 65 years, lipase > upper normal limit and preoperative shock were independent risk factors of mortality in postoperative perforated peptic ulcer. Lipase > upper normal limit is needed for further research on the influence on mortality.

Abstract
OBJECTIVE Mortality and morbidity following perforated peptic ulcer (PPU) is substantial and probably related to the development of sepsis. During the last three decades a large number of preoperative prognostic factors in patients with PPU have been examined. The aim of this systematic review was to summarize available evidence on these prognostic factors. MATERIAL AND METHODS MEDLINE (January 1966 to June 2009), EMBASE (January 1980 to June 2009), and the Cochrane Library (Issue 3, 2009) were screened for studies reporting preoperative prognostic factors for mortality in patients with PPU. The methodological quality of the included studies was assessed. Summary relative risks with 95% confidence intervals for the identified prognostic factors were calculated and presented as Forest plots. RESULTS Fifty prognostic studies with 37 prognostic factors comprising a total of 29,782 patients were included in the review. The overall methodological quality was acceptable, yet only two-thirds of the studies provided confounder adjusted estimates. The studies provided strong evidence for an association of older age, comorbidity, and use of NSAIDs or steroids with mortality. Shock upon admission, preoperative metabolic acidosis, tachycardia, acute renal failure, low serum albumin level, high American Society of Anaesthesiologists score, and preoperative delay >24 h were associated with poor prognosis. CONCLUSIONS In patients with PPU, a number of negative prognostic factors can be identified prior to surgery, and many of these seem to be related to presence of the sepsis syndrome.

Abstract
BACKGROUND/PURPOSE Many studies have assessed the major risk factors for mortality or morbidity in surgical patients with perforated peptic ulcer (PPU). The aim of our study was to focus on survivors and to investigate the predictive factors for length of hospital stay (LOHS) for surgical patients. METHODS The medical records of 195 patients who survived surgery were reviewed retrospectively. The following factors were analyzed: patient profile, associated medical illnesses, diagnostic methods, fever, preoperative shock, clinical data from the emergency room, delays in surgery, sites of perforation, operative methods, positive ascites culture and species of microorganism, postoperative infection, and noninfective postoperative complications. RESULTS Univariate analysis showed that the following factors were significantly related to longer LOHS: age > 65 years, liver cirrhosis, diabetes mellitus, history of peptic ulcer disease, number of comorbid diseases, preoperative shock, creatinine > 1.5 mg/dL, surgical delay of > 12 hours, and all postoperative factors except species of microorganisms in ascites culture. In a multivariate linear regression model, catheter infection, pneumonia, urinary tract infection, wound infection, bacteremia, non-infective abdominal complications, other infections, surgical delay of > 12 hours, and comorbidity were major factors associated with longer LOHS. CONCLUSION A predictive model was established with nine factors that explained 71.6% of the variation in LOHS of patients who survived surgery for PPU. Several corrective methods based on the model can be devised by attending physicians to shorten LOHS.

Abstract
AIM To evaluate risk factors, morbidity and mortality rates of perforated peptic ulcer (PPU) and to investigate factors affecting postoperative complications of PPU. BACKGROUND The incidence of PPU has remained constant, simple closure with omental patch repair being the mainstay of treatment. PATIENTS AND METHODS One hundred and nineteen patients admitted to Al-Ain Hospital with PPU between January 2000 and March 2004 was studied retrospectively; two with deficient data were excluded from the analysis. Logistic regression was used to define factors affecting postoperative complications. RESULTS The mean age of patients was 35.3 years (range, 20-65). 45.7% of patients were Bangladeshi, and 85.3% originated from the Indian subcontinent. One patient, subsequently found to have a perforated gastric cancer, died. In 116 patients, 26 complications were recorded in 20 patients (17.2%). Common risk factors for perforation were smoking, history of peptic ulcer disease (PUD) and use of non-steroidal anti-inflammatory drugs (NSAIDs). A significantly increased risk of perforation was evident during the daytime fasting month of Ramadan. An increase in the acute physiology and chronic health evaluation (APACHE) II score (p = 0.047) and a reduced white blood cell count (0.04) were highly significant for the prediction of postoperative complications. CONCLUSION Patients with dyspeptic symptoms and a history of previous PUD should be considered for prophylactic treatment to prevent ulcer recurrence during prolonged daytime fasting in Ramadan, especially during the winter time.

Abstract
OBJECTIVE The overall mortality for patients undergoing surgery for perforated peptic ulcer has increased despite improvements in perioperative monitoring and treatment. The objective of this study was to identify and describe perioperative risk factors in order to identify ways of optimizing the treatment and to improve the outcome of patients with perforated peptic ulcer. MATERIAL AND METHODS Three hundred and ninety-eight patients undergoing emergency surgery in four university hospitals in Denmark were included in the study. Information regarding the pre-, intra- and postoperative phases were recorded retrospectively from medical records. Data were analysed using multiple logistic regression analysis. The primary end-point was 30-day mortality. RESULTS The 30-day mortality rate was 27%. The following variables were independently associated with death within 30 days of surgery: ASA (American Society of Anaesthesiologists) class, age, shock upon admission, preoperative metabolic acidosis, elevated concentration of creatinine upon admission, subnormal concentration of albumin upon admission and insufficient postoperative nutrition. CONCLUSIONS Thus, preoperative metabolic acidosis, renal insufficiency upon admission and insufficient postoperative nutrition have been added to the list of independent risk factors for death within 30 days of surgery in patients with peptic ulcer perforation. Finding that shock upon admission, reduced albumin blood levels upon admission, renal insufficiency upon admission and preoperative metabolic acidosis are independently related to 30-day mortality could indicate that patients with peptic ulcer perforation are septic upon admission, and thus might benefit from a perioperative care protocol with early source control and early goal-directed therapy according to The Surviving Sepsis Campaign. This hypothesis should be addressed in future studies.

Abstract
Despite the introduction of histamine H2-receptor antagonists, proton-pump inhibitors and the discovery of Helicobacter pylori, both the incidence of emergency surgery for perforated peptic ulcer and the mortality rate for patients undergoing surgery for peptic ulcer perforation have increased. This increase has occurred despite improvements in perioperative treatment and monitoring. To improve the outcome of these patients, it is necessary to investigate the reasons behind this high mortality rate. In this review we evaluate the existing evidence in order to identify significant risk factors with an emphasis on risks that are preventable. A systematic review including randomized studies was carried out. There are a limited number of studies of patients with peptic ulcer perforation. Most of these studies are of low evident status. Only a few randomized, controlled trials have been published. The mortality rate and the extent of postoperative complications are fairly high but the reasons for this have not been thoroughly explained, even though a number of risk factors have been identified. Some of these risk factors can be explained by the septic state of the patient on admission. In order to improve the outcome of patients with peptic ulcer perforation, sepsis needs to be factored into the existing knowledge and treatment.

Abstract
BACKGROUND It is not clear whether the incidence or early mortality related to peptic ulcer perforation has changed. AIM To evaluate the incidence and mortality related to peptic ulcer perforation while considering the intake of low-dose aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs). METHODS We recorded the numbers and details of all patients presenting in our region of Scotland with perforation between 1997 and 2006 including demography, drug usage and 30-day mortality. RESULTS In subjects aged >65 years, the annual incidence of perforation was 32.7 per 10(5) of the age-specific population, of whom 10.7 per 10(5) were taking low-dose aspirin and 12.0 taking NSAIDs. These were all significantly higher (P < 0.001) than the corresponding incidence in subjects aged < or =65 years (6.6 per 10(5) overall, 1.1 taking aspirin and 2.5 taking NSAIDs). There was an increasing trend with time in the number of patients taking NSAIDs (chi(2) = 4.57, P = 0.03). Using univariate analysis, 30-day mortality was associated with aspirin [odds ratio, 2.32 (95% C.I., 1.20-4.47), P = 0.01] but not with NSAIDs. The strongest predictors of mortality were increasing age and comorbidity. CONCLUSIONS Perforation remains common in elderly patients including users of NSAIDs and aspirin. Early mortality is also noted in association with increasing age and comorbidity, but not independently with drug intake.

Abstract
INTRODUCTION Perforated peptic ulcer disease continues to inflict high morbidity and mortality. Although patients can be stratified according to their surgical risk, optimal management has yet to be described. In this study we demonstrate a treatment option that improves the mortality among critically ill, poor risk patients with perforated peptic ulcer disease. METHODS In our study, two series were retrospectively reviewed: group A patients (n = 522) were treated in a single surgical unit at the Dhaka Medical College Hospital, Dhaka, Bangladesh during the 1980s. Among them, 124 patients were stratified as poor risk based on age, delayed presentation, peritoneal contamination, and coexisting medical problems. These criteria were the basis for selecting a group of poor risk patients (n = 84) for minimal surgical intervention (percutaneous peritoneal drainage) out of a larger group of patients, group B (n = 785) treated at Khulna Medical College Hospital during the 1990s. RESULTS In group A, 479 patients underwent conventional operative management with an operative mortality of 8.97%. Among the 43 deaths, 24 patients were >60 years of age (55.8%), 12 patients had delayed presentation (27.9%), and 7 patients were in shock or had multiple coexisting medical problems (16.2%). In group B, 626 underwent conventional operative management, with 26 deaths at a mortality rate of 4.15%. Altogether, 84 patients were stratified as poor risk and were managed with minimal surgical intervention (percutaneous peritoneal drainage) followed by conservative treatment. Three of these patients died with an operative mortality of 3.5%. CONCLUSIONS Minimal surgical intervention (percutaneous peritoneal drainage) can significantly lower the mortality rate among a selected group of critically ill, poor risk patients with perforated peptic ulcer disease.

Abstract
BACKGROUND Although the detection of pediatric peptic ulcer disease (PUD) has recently been increasing, perforated peptic ulcer (PPU) in children is rare. We report our experience with PPU in children. MATERIALS AND METHODS The charts of children diagnosed with PPU at our hospital from January 1986 to June 2005 were reviewed. Data were obtained on demographics, coexisting clinical events, perforation sites, delay in surgery, operative findings and methods, and outcomes. The data were analyzed using the chi2, Student t test, and multivariate logistic regression for possible risk factors. RESULTS There were 42 male and 10 female patients aged 2 to 18 years (mean, 14.2 years) included in the study. Forty-seven patients were adolescents (90%). Eight patients had coexisting clinical events before PPU. All of the patients manifested acute abdominal pain. Forty-nine patients (94.2%) had peritoneal signs. Radiography showed subdiaphragmatic free air in 43 patients (82.7%); this was the most important tool for establishing diagnosis. Nine patients (17.3%) had postoperative complications. Two patients died (3.8%). Univariate analysis showed that poor outcome was significantly associated with female sex, more coexisting clinical events, no evidence of chronic ulcer, and treatment by simple suture (P < 0.05). Only female sex and simple suture remained statistically significant in multivariate analysis. Although delay in surgery (>12 hours) was not significantly related to complications, there was a greater tendency toward the development of complications. CONCLUSIONS PPU should be suspected in adolescents who manifest acute abdominal pain and have peritoneal signs. Children with PPU have a more favorable outcome than adults.

Abstract
BACKGROUND AND AIM With the introduction of H2 receptor antagonists and proton pump inhibitors, the incidence of elective surgery for peptic ulcer (PU) diseases has decreased, although complications of PU such as perforation and bleeding have remained fairly constant. The purpose of this study was to identify the risk factors that predict morbidity and mortality in patients with perforated PU. METHODS The records of 269 patients who were operated on for perforated PU were reviewed retrospectively. The following factors were analyzed in terms of morbidity and mortality: age >65 years; gender; associated medical illness; chronic ingestion of non-steroidal anti-inflammatory drugs, aspirin, corticosteroids or immunosuppressants; alcohol ingestion and smoking habits; American Society of Anesthesiologist (ASA) status; season; delayed operation; site of ulcer perforation; and shock on admission and type of operation. RESULTS There were 30 female (11.16%) and 239 male (88.84%) patients. Seventy-one (26.4%) patients had associated diseases. Simple closure was performed in 257 (95.5%) patients; 12 patients (4.5%) underwent definitive operations. A total of 108 postoperative complications were present in 65 (24.2%) patients. Twenty-three patients died (8.55%). Multivariate analysis showed that only age, ASA score, treatment delay, presence of shock and definitive operation were independent predictors of mortality. Significant risk factors that led to morbidity were ASA status, time of surgery, season, presence of shock and type of surgery. There was a significant difference concerning morbidity and mortality between simple closure of the perforation and definitive surgery. CONCLUSIONS Age, delayed surgery, presence of shock, ASA risk and definitive surgery are factors significantly associated with fatal outcomes in patients undergoing emergency surgery for perforated PU. Therefore, proper resuscitation from shock, improving ASA grade, decreasing delay and reserving definitive surgery for selected patients is needed to improve overall results.

Abstract
Background With dwindling rates of postoperative mortality in perforated peptic ulcer that is attributable to H2-receptor blocker usage, there is a need to shift the focus towards the prevention of postoperative morbidity. Further, the simultaneous contribution of several putative clinical predictors to this postoperative morbidity is not fully appreciated. Our objective was to assess the predictors of the risk, rate and number of postoperative complications in surgically treated patients of perforated peptic ulcer. Methods In a prospective cohort study of 96 subjects presenting as perforated peptic ulcer and treated using Graham's omentoplatsy patch or gastrojejunostomy (with total truncal vagotomy), we assessed the association of clinical predictors with three domains of postoperative complications: the risk of developing a complication, the rate of developing the first complication and the risk of developing higher number of complications. We used multiple regression methods – logistic regression, Cox proportional hazards regression and Poisson regression, respectively – to examine the association of the predictors with these three domains. Results We observed that the risk of developing a postoperative complication was significantly influenced by the presence of a concomitant medical illness [odds ratio (OR) = 8.9, p = 0.001], abdominal distension (3.8, 0.048) and a need of blood transfusion (OR = 8.2, p = 0.027). Using Poisson regression, it was observed that the risk for a higher number of complications was influenced by the same three factors [relative risk (RR) = 2.6, p = 0.015; RR = 4.6, p < 0.001; and RR = 2.4, p = 0.002; respectively]. However, the rate of development of complications was influenced by a history suggestive of shock [relative hazards (RH) = 3.4, p = 0.002] and A- blood group (RH = 4.7, p = 0.04). Conclusion Abdominal distension, presence of a concomitant medical illness and a history suggestive of shock at the time of admission warrant a closer and alacritous postoperative management in patients of perforated peptic ulcer.

Abstract
The primary goal of this study was to describe epidemiology and management strategies of the perforated duodenal ulcer, as well as the most common methods of laparoscopic perforated duodenal ulcer repair. The secondary goal was to demonstrate the value of prospective and retrospective studies regarding the early results of surgery and the risk factors. The tertiary goal was to emphasize the benefits of this operation, and the fourth goal was to clarify the possible risk factors associated with laparoscopic repair of the duodenal ulcer. The Medline/Pubmed database was used. Review was done after evaluation of 96 retrieved full-text articles. Thirteen prospective and twelve retrospective studies were selected, grouped, and summarized. The spectrum of the retrospective studies' results are as follows: median overall morbidity rate 10.5 %, median conversion rate 7%, median hospital stay 7 days, and median postoperative mortality rate 0%. The following is the spectrum of results of the prospective studies: median overall morbidity rate was slightly less (6%); the median conversion rate was higher (15%); the median hospital stay was shorter (5 days) and the postoperative mortality was higher (3%). The risk factors identified were the same. Shock, delayed presentation (> 24 hours), confounding medical condition, age > 70 years, poor laparoscopic expertise, ASA III-IV, and Boey score should be considered preoperative laparoscopic repair risk factors. Each of these factors independently should qualify as a criterion for open repair due to higher intraoperative risks as well as postoperative morbidity. Inadequate ulcer localization, large perforation size (defined by some as > 6 mm diameter, and by others as > 10 mm), and ulcers with friable edges are also considered as conversion risk factors.

Abstract
BACKGROUND Perforated peptic ulcer is a common abdominal disease that is treated by surgery. The development of laparoscopic surgery has changed the way to treat such abdominal surgical emergencies. The results of some clinical trials suggest that laparoscopic surgery could be a better strategy than open surgery in the correction of perforated peptic ulcer but the evidence is not strongly in favour or against this intervention. OBJECTIVES To measure the effect of laparoscopic surgical treatment versus open surgical treatment in patients with a diagnosis of perforated peptic ulcer in relation to abdominal septic complications, surgical wound infection, extra-abdominal complications, hospital length of stay and direct costs. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (CENTRAL) on The Cochrane Library (Issue 2, 2004), PubMed/MEDLINE (1966 to July 2004), EMBASE (1985 to November 2004) and LILACS (1988 to November 2004) as well as reference lists of relevant articles. SELECTION CRITERIA Randomised clinical trials comparing laparoscopic surgery versus open surgery for the repair of perforated peptic ulcer using any mechanical method of closure (suture, omental patch or fibrin sealant). DATA COLLECTION AND ANALYSIS Primary outcome measures included proportion of septic and other abdominal complications (surgical site infection, suture leakage, intra-abdominal abscess, postoperative ileus) and extra-abdominal complications (pulmonary). Secondary outcomes included mortality, time to return to normal diet, time of nasogastric aspiration, hospital length of stay and costs. Outcomes were summarized by reporting odds ratios and 95% confidence intervals, using the fixed-effect model. MAIN RESULTS We included two randomised clinical trials, which were of acceptable quality. We found no statistically significant differences between laparoscopic and open surgery in the proportion of abdominal septic complications (OR 0.66, 95% CI 0.30 to 1.47), pulmonary complications (OR 0.37, 95% CI 0.11 to 1.31) or actual number of septic abdominal complications (OR 0.72, 95% CI 0.33 to 1.58). Heterogeneity was significant only for pulmonary complications. AUTHORS' CONCLUSIONS This systematic review suggests that a decrease in septic abdominal complications may exist when laparoscopic surgery is used to correct perforated peptic ulcer. However, it is necessary to develop more randomised controlled trials that include a greater number of patients to confirm such an assumption, guaranteeing a long learning curve for participating surgeons. With the information provided by the available clinical trials it could be said that laparoscopic surgery results are not clinically different from those of open surgery.

Abstract
GOALS The aim of this study was to evaluate our results of laparoscopic treatment of perforated gastroduodenal ulcers during a 5-year period and to compare the outcome of open and laparoscopic surgery. BACKGROUND The value of laparoscopic treatment of gastroduodenal ulcers is still controversially debated because its superiority to conventional open surgery has not been established. STUDY From January 1996 to December 2001, 24 patients were treated laparoscopically and 31 patients underwent conventional open suture repair. The results of these patients were retrospectively reviewed. RESULTS There were 55 patients with a mean age of 55 years (range 18-92 years) who were eligible for the study. Patients with laparoscopic repair had a lower mean ASA score (2 vs. 2.9; P = 0.02) and a less severe Mannheimer peritonitis index (16.5 vs. 21; P = 0.00001) compared with patients with open repair. Three patients who were begun by the laparoscopic approach had to be converted to open surgery (12.5%). Three patients who underwent open repair died postoperatively (5.5%). There was no difference between treatment groups regarding operative time, morbidity, or postoperative hospital stay. The laparoscopic group required significantly fewer analgesics postoperatively (2.2 vs. 4 dosages; P = 0.04). CONCLUSIONS Laparoscopic treatment of perforated gastroduodenal ulcers is an effective treatment option and should be considered in suited patients for the initial approach.

Abstract
Patients with longer duration of huge gastroduodenal perforation are known to be difficult to tolerate major surgery. Primary closure of the perforation will result in suture tension with high risk of dehiscence, gastric outlet obstruction, and even mortality. Teflon-Felt is a bioinert, polytetrafluoroethylene, flexible material used on patients with vascular defect. It is proposed that Teflon-Felt may be an optimal material for closure of giant gastroduodenal perforation to reduce suture tension without narrowing of the gastric outlet.
