Predicting in-hospital mortality risk for perforated peptic ulcer surgery: the PPUMS scoring system and the benefit of laparoscopic surgery: a population-based study. Surg Endosc 2023; 37:6834-6843. [PMID: 37308764 DOI: 10.1007/s00464-023-10180-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 05/30/2023] [Indexed: 06/14/2023]
Abstract
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.

Wang YL, Chan XW, Chan KS, Shelat VG. Omental patch repair of large perforated peptic ulcers ≥25 mm is associated with higher leak rate. J Clin Transl Res 2021; 7:759-766. [PMID: 34988327 PMCID: PMC8710357] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/02/2021] [Accepted: 11/07/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND AND AIM Omental patch repair is the present gold-standard technique for patients with perforated peptic ulcers (PPUs). Data are lacking regarding the safe ulcer size for omental patch repair leak (OPL). We analyze our experience in managing PPU to identify an ulcer size cut-off for predicting OPL. METHODS Patients who had undergone omental patch repair for PPU between Jan 2004 and Apr 2016 were included. Demographic data, the American Society of Anesthesiologists score, ulcer size, operative approach, post-operative complications, and length of stay were recorded. OPL, intra-abdominal collection, repeat surgery, and 30-day mortality were recorded. The relationship between ulcer size, pre-operative characteristics, and OPL were investigated with univariate and multivariate logistic regression. Receiver operating characteristic curve analysis derived the ulcer size cut-off to predict OPL. In addition, we analyzed if ulcer size predicted mortality or malignancy. RESULTS Six hundred and ninety patients with a mean age of 55.1 years (range 16-94) were managed for PPU during the study period. Free air on X-ray was evident in 417 (60.4%) patients. Mean ulcer size was 7.8 mm (range 1-50). OPL occurred in 15 patients (2.2%) and 30-day mortality was 7.4% (n=51). Multivariate analysis found ulcer size increase of 10 mm (OR 3.30, 95% CI 1.81-6.02, P<0.001) predicted increased risk of OPL. At 25 mm cut-off, sensitivity was 26.7%, specificity was 97.2%, positive likelihood ratio was 9.47, and negative likelihood ratio was 0.76 for OPL. CONCLUSION Ulcer size increase in 10 mm increases leak rate by 3.3 times. Ulcer size ≥25 mm predicts OPL. RELEVANCE FOR PATIENTS Increased risk of OPL for ≥25 mm warrants need for close post-operative monitoring and lowers threshold for investigations in event of clinical deterioration. Decision for omental patch repair versus gastrectomy however should not be based on ulcer size alone.

Abstract
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.

Abstract
BACKGROUND Nonoperative management (NOM) is a promising therapeutic modality for patients with perforated peptic ulcer (PPU). However, the risk factors for poor efficacy and adverse events of NOM are a concern.
AIM To investigate the factors predictive of poor efficacy and adverse events in patients with PPU treated by NOM.
METHODS This retrospective case-control study enrolled 272 patients who were diagnosed with PPU and initially managed nonoperatively from January 2014 to December 2018. Of these 272 patients, 50 converted to emergency surgery due to a lack of improvement (surgical group) and 222 patients were included in the NOM group. The clinical data of these patients were collected. Baseline patient characteristics and adverse outcomes were compared between the two groups. Logistic regression analysis and receiver operating characteristic curve analyses were conducted to investigate the factors predictive of poor efficacy of NOM and adverse outcomes in patients with PPU.
RESULTS Adverse outcomes were observed in 71 patients (32.0%). Multivariate analyses revealed that low serum albumin level was an independent predictor for poor efficacy of NOM and adverse outcomes in patients with PPU.
CONCLUSION Low serum albumin level may be used as an indicator to help predict the poor efficacy of NOM and adverse outcomes, and can be used for risk stratification in patients with PPU.

Abstract
Background: Fungal isolates from peritoneal fluid sampling in patients with perforated peptic ulcer (PPU) is not uncommon and its management unclear. This study aims to evaluate whether the presence of fungus in peritoneal fluid cultures is a predictor of morbidity and mortality after laparotomy for PPU. Method: This is a single-center retrospective study including adult patients with perforated gastric and duodenal ulcers over a 10-year period (January 2004 to January 2014). Evaluation of predictors contributing to fungal growth was conducted using multiple logistic regression analysis. Operative factors and 30-day mortality and morbidity outcomes were compared against fungal growth using a multivariable generalized linear mixed model analysis. Results: The median age was 58 (interquartile range [IQR] 44-70) years with 110 (20.3%) females. In addition to hypertension and hyperlipidemia, diabetes mellitus (13.5%), ischemic heart disease (2.6%), and heart failure (2.4%) were common. Fungus was cultured from peritoneal fluid in 209 (38.6%) patients. Median American Society of Anesthesiology (ASA) score was 2 (IQR 2-3) and median Mannheim peritonitis index (MPI) score was 15 (IQR 10-20). Free air was detected in 323 (59.6%) patients and 52 (9.6%) patients had gastrectomy. Median length of stay was 7 (IQR 6-11) days. All-cause complications were seen in 53 (9.8%) patients, of whom 37 patients (6.8%) developed intra-abdominal collection, 20 patients (3.7%) had anastomotic leakage, and 12 patients (2.2%) required repeat operation. Thirty-day mortality was seen in 47 (8.7%) patients. Multivariable analysis showed age (median age, 64; IQR 53-74) as a predictor of fungal growth (p < 0.001) but fungal growth not a predictor of adverse peri-operative outcomes. Conclusion: Fungal isolates in peritoneal fluid cultures are more likely to occur in older patients who have PPU. Presence of fungal isolates does not impact peri-operative outcomes.

Abstract
Background: Peptic ulcer perforation is a deadly complication of duodenal ulcers. The literature is still sparse in terms of giant duodenal perforations. There exist a variety of techniques to decompress the duodenum after repair which leave the patient with multiple ostomies that require extensive postoperative care. Case presentation: In this case we present a patient with AIDS who was found to have a large duodenal ulcer perforation. Intraoperatively the fragility of the patient’s duodenum warranted a method of decompression that would keep the integrity of the duodenal tissue. The common method of lateral duodenostomy was not the best option and instead a gastro-jejunal feeding tube was altered into a gastro-duodenal tube to avoid creating another ostomy. Postoperatively she did not show signs of leak, but eventually died from sepsis secondary to fulminant AIDS. Conclusions: We propose this technique as a novel method of decompressing the duodenum. This new method eliminates the need for excessive ostomies and has the possibility to make the postoperative transition simpler.

Abstract
PURPOSE Marginal ulcer (MU) is defined as ulcer on the jejunal side of the gastrojejunostomy (GJ) anastomosis. Most MUs are managed medically but those with complications like bleeding or perforation require intervention. It is recommended that GJ anastomosis be revised in patients with MU perforation (MUP). The aim of this case series is to study the clinical presentation and management of MUP. METHODS Three hundred and thirty-two patients who underwent emergency surgery for perforated peptic ulcer at a single center were studied over a period of 5 years. RESULTS Nine patients (2.7 %) presented with MUP. GJ was previously done for either complicated peptic ulcer (n = 4) or for suspected gastric malignancy (n = 5). Two patients had previously completed H. pylori therapy. None of the patients presented with septic shock. MU was on the jejunal side of GJ in all patients. The median MUP size was 10 mm. Four patients (44.4 %) had omental patch repair, three (33.3 %) had primary closure, and one each had revision of GJ and jejunal serosal patch repair. There were no leaks, intra-abdominal abscess or reoperation and no malignancies. CONCLUSION MUP patients do not present with septic shock. Omental patch repair or primary closure is sufficient enough. Revision of Billroth-II-GJ into Roux-en-Y-GJ is not mandatory.

Abstract
Peptic ulcer disease (PUD) affects 4 million people worldwide annually. The incidence of PUD has been estimated at around 1.5% to 3%. Perforated peptic ulcer (PPU) is a serious complication of PUD and patients with PPU often present with acute abdomen that carries high risk for morbidity and mortality. The lifetime prevalence of perforation in patients with PUD is about 5%. PPU carries a mortality ranging from 1.3% to 20%. Thirty-day mortality rate reaching 20% and 90-d mortality rate of up to 30% have been reported. In this review we have summarized the current evidence on PPU to update readers. This literature review includes the most updated information such as common causes, clinical features, diagnostic methods, non-operative and operative management, post-operative complications and different scoring systems of PPU. With the advancement of medical technology, PUD can now be treated with medications instead of elective surgery. The classic triad of sudden onset of abdominal pain, tachycardia and abdominal rigidity is the hallmark of PPU. Erect chest radiograph may miss 15% of cases with air under the diaphragm in patients with bowel perforation. Early diagnosis, prompt resuscitation and urgent surgical intervention are essential to improve outcomes. Exploratory laparotomy and omental patch repair remains the gold standard. Laparoscopic surgery should be considered when expertise is available. Gastrectomy is recommended in patients with large or malignant ulcer.
