Evaluating the Evolving Morbidity of Omentoplasty for Perforated Peptic Ulcer Disease

A systematic review and meta-analysis comparing postoperative outcomes of laparoscopic versus open omental patch repair of perforated peptic ulcer

BACKGROUND

The mainstay of surgical management of perforated peptic ulcer is omental patch repair. Advances in minimally invasive techniques have shown feasibility of laparoscopic omental patch repair (LOPR). Laparoscopic omental patch repair is limited by learning curve (LC), but there is a lack of reporting of LC in LOPR. This study aims to compare outcomes following LOPR versus open omental patch repair (OOPR) with reporting of LC.

METHODS

PubMed, Embase, The Cochrane Library, and Scopus were systematically searched from inception till January 2022 for randomized controlled trials (RCTs) and non-RCTs comparing LOPR and OOPR in perforated peptic ulcer. Exclusion criteria were primary repair without use of omental patch repair. Primary outcomes were 30-day mortality, postoperative leak, and LC analysis.

RESULTS

There were a total of 29 studies including 5,311 patients (LOPR, n = 1,687; OOPR, n = 3,624), with 4 RCTs with 238 patients (LOPR, n = 118; OOPR, n = 120). Majority of ulcers were located in the duodenum (57.0%) followed by stomach (30.7%). Mean ulcer size ranged from 5 to 16.2 mm in LOPR and 4.7 to 15.8 mm in OOPR. Laparoscopic omental patch repair was associated with lower 30-day mortality (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.35-0.92; p = 0.02), overall morbidity (OR, 0.31; 95% CI, 0.18-0.53; p < 0.0001), surgical site infection (OR, 0.27; 95% CI, 0.18-0.42; p < 0.00001), and length of stay (mean difference, -2.84 days; 95% CI, -3.63 to -2.06; p < 0.00001). Postoperative leakage (OR, 1.06; 95% CI, 0.43-2.61; p = 0.90) was comparable between LOPR and OOPR. Only three studies analyzed the proportion of consultants to trainees; LOPR was performed mainly by consultants (range, 82.4-91.4%), while OOPR was mainly performed by trainees (range, 52.8-96.8%). One study showed that consultants who performed open conversion had shorter operating time compared with chief residents (85 vs. 186.6 minutes, p < 0.003).

CONCLUSION

Laparoscopic omental patch repair has lower mortality, overall morbidity, length of stay, intraoperative blood loss, and postoperative pain compared with OOPR. More prospective studies should be conducted to evaluate LC in LOPR.

Surgical Management of Perforated Peptic Ulcer: A Comparative Meta-analysis of Laparoscopic Versus Open Surgery

BACKGROUND

Despite the widescale success of proton pump inhibitors to reducing the incidence of peptic ulcer disease, perforated peptic ulcer (PPU) remains a significant cause of severe complications and death. The implementation of open or surgical repair of PPU should be guided by reliable guidelines which are based on current systematic evidence.

OBJECTIVES

To assess the comparative efficacy and safety of laparoscopic and open repair of PPU.

METHODS

A systematic review and meta-analysis was conducted based on retrospective, prospective cohort studies, and randomized clinical trials. Duration of surgery and postoperative complications and death were collected from eligible studies, and the outcomes were pooled using mean differences (MD) or relative risks (RRs) for numerical and binary outcomes, respectively. The estimated variance was expressed as 95% confidence intervals (95% CIs).

RESULTS

Forty-five studies were included (8456 patients, 56.08% underwent open repair, 6 prospective studies, 7 randomized clinical trials, and 32 retrospective studies). Compared with open repair, laparoscopic surgeries were associated with longer operative times (MD=8.36, 95% CI, 0.49-16.22), shorter hospital stay (MD=-2.74, 95% CI, -3.70 to-1.79), a higher risk of suture leakage (RR=1.91, 95% CI, 1.04-3.49) and lower risks of mortality (RR=0.57, 95% CI, 0.47-0.70), septic shock (RR=0.69, 95% CI, 0.49-0.98), renal failure (RR=0.38, 95% CI, 0.18-0.79), and wound infection (RR=0.26, 95% CI, 0.19-0.37).

CONCLUSION

Laparoscopic repair of PPU showed promising safety outcomes; however, future well-designed randomized studies are warranted to reduce the observed performance bias and possible selection bias in individual studies.

Outcomes of surgical management of peptic ulcer perforation using the falciform ligament: A cross-sectional study at a single centre in Vietnam

Introduction

Peptic ulcer perforation (PUP) is one of the most common critical surgical emergencies. The omentum flap is commonly used to cover a PUP. However, the omentum cannot be used in cases of severe peritonitis or previous surgical removal. This is the first study conducted in Vietnam that was designed to analyse the outcomes of patients with PUPs who were treated using the falciform ligament.

Method

In this study, we retrospectively identified 40 consecutive patients who were treated for PUP at a single high-volume centre in Vietnam from February 2018 to February 2021. Peptic ulcer perforation was measured during diagnostic evaluation based on preoperative imaging, such as X-ray, and CT scan. Patients who had malignancy, laparoscopic surgery, omentopexy and nonoperative treatment were excluded from this research.

Results

Forty patients were included; the mean age of the patients was 66.3 years (range 33–99 years), and some patients had comorbid disease (57.5%), hypertension (30%), diabetes (10%), cirrhosis (7.5%), and chronic renal failure (7.5%). The PUPs were located in the duodenum (80%), or the pyloric (15%) and prepyloric (5%) regions. The procedures used to treat the patients included duodenostomy (32.5%), gastrojejunostomy (37.5%), and antrum resection (2.5%). The average operative time was 88.6 min (45–180 min), hospital stay was 9.6 days (2–35 days), and oral intake was started at 4.1 days (3–8 days); additionally, the 30-day mortality (17.5%) and incidences of pneumonia (25%), multiorgan failure (15%), acute liver failure (5%), wound infection (7.5%), and ulcer peptic fistula (0%) were assessed. Univariate tests showed that an ASA ≥ III and comorbidities, such as pulmonary complications, liver failure and multiorgan failure, were associated with mortality. The multivariate test showed that multiorgan failure was the only factor related to mortality.

Conclusion

The falciform ligament can be efficiently used for the closure of a PUP. Although there were no instances of complication with a reperforated peptic ulcer, the mortality rate was slightly highly related to severe comorbidities and postoperative multiorgan failure.

•

Peptic ulcer perforation is one of the most common surgical emergencies with an overall mortality rate is between 1.3% and 20%.

•

Comorbidities, over 70 years old, having surgical therapy after 36 hours, and postoperative complications are associated with mortality.

•

Using falciform ligament to replace the traditional omental patch is interesting, easy applying and efficiently in the closure of PUP.

•

The mortality and complications were still high related to severe comorbidity and multiorgan failure after surgery.
