Is operative management effective in treatment of perforated typhoid?

Typhoid intestinal perforation in Francophone Africa, a scoping review

Typhoid intestinal perforation (TIP) is a leading cause of peritonitis and indication for emergency surgery in Africa, with reported mortality rates up to 30% in pediatric patients. Currently, data on TIP in Western databases are primarily from countries that speak English, likely due to non-English publication and citation biases. Despite the high burden of infectious diseases in Francophone Africa, data from these countries regarding TIP remain limited. This study aims to highlight the incidence and morbidity of TIP in Francophone African countries using an extended search algorithm. We conducted a scoping review using the PubMed, EMBASE, and SCOPUS databases with the keywords "peritonitis", "non-traumatic ileal perforation", and "typhoid" in Francophone African countries. Additionally, we contacted surgeons in Africa and concurrently used citation chasing to obtain data not found in western databases. In total, 32 studies from 12 countries were identified and included in this review. A total of 22 publications were in French. Patient median age was 20 years and TIP caused a median of 35% of acute peritonitis cases. Mortality rates ranged from 6-37% (median: 16%). Rate of complications ranged from 15-92% (median: 46%). Ileostomy creation as a treatment for TIP varied between hospitals (0-79%), with the highest rates reported in Niger. In Francophone Africa, TIP is associated with high morbidity and mortality, most commonly in children and young adults. Interventions, including improved sanitation and the introduction of typhoid conjugate vaccines into routine vaccination programs, have the potential to significantly decrease typhoid fever and its complications.

Causes of Acute Peritonitis and Its Complication

Introduction

Peritonitis is a significant cause of morbidity and mortality in surgical settings. Coexisting premorbid illness and postoperative complications were found to be associated with death. This study aimed to analyze various etiologies that cause peritonitis and shed light on the factors responsible for unsatisfactory results.

Method

This longitudinal study included 309 patients above 12 years of age, of either gender, with confirmed diagnosis of peritonitis. Exploratory laparotomy was done to identify the cause of peritonitis. Patients were monitored postoperatively till their discharge or death for the development of complications.

Results

Our results showed that the most common cause of acute peritonitis was duodenal perforation (26.2%), followed by typhoid ileal perforation (24.2%) and ruptured appendix (16.8%). At least one complication was observed in 31% of the participants. The most common complication was dehydration (18.8%), followed by septicemia (11.3%) and paralytic ileus (6.4%). Ten (3.2%) patients died in the hospital.

Conclusions

Acute peritonitis is a serious surgical emergency caused by a number of diseases. Early surgical treatment along with antibiotics, followed by aggressive resuscitation can yield improved outcomes in patients with peritonitis.

Burden of Ileal Perforations Among Surgical Patients Admitted in Tertiary Care Hospitals of Three Asian countries: Surveillance of Enteric Fever in Asia Project (SEAP), September 2016-September 2019

Background

Typhoid fever is caused by Salmonella enterica subspecies enterica serovar Typhi (S. Typhi) and can lead to systemic illness and complications. We aimed to characterize typhoid-related ileal perforation in the context of the population-based Surveillance of Enteric Fever in Asia Project (SEAP) in Bangladesh, Nepal and Pakistan.

Methods

Between September 2016 and September 2019, all cases of nontraumatic ileal perforation with a clinical diagnosis of typhoid were enrolled from 4 tertiary care hospitals in Karachi, 2 pediatric hospitals in Bangladesh, and 2 hospitals in Nepal. Sociodemographic data were collected from patients or their caregivers, and clinical and outcome data were retrieved from medical records. Tissue samples were collected for histopathology and blood cultures where available.

Results

Of the 249 enrolled cases, 2 from Bangladesh, 5 from Nepal and 242 from Pakistan. In Pakistan, most of the cases were in the 0–15 (117/242; 48%) and 16–30 (89/242; 37%) age groups. In all countries, males were most affected: Pakistan 74.9% (180/242), Nepal 80% (4/5), and Bangladesh 100% (2/2). Blood culture was done on 76 cases; 8 (11%) were positive for S. Typhi, and all were extensively drug resistant (XDR) S. Typhi. Tissue cultures was done on 86 patients; 3 (3%) were positive for S. Typhi, and all were XDR S. Typhi, out of 86 samples tested for histopathology 4 (5%) revealed ileal perforation with necrosis. Culture or histopathology confirmed total 15 (11%) enteric fever cases with ileal perforation are similar to the clinically diagnosed cases. There were 16/242 (7%) deaths from Pakistan. Cases of ileal perforation who survived were more likely to have sought care before visiting the sentinel hospital (P = .009), visited any hospital for treatment (P = .013) compared to those who survived.

Conclusions

Although surveillance differed substantially by country, one reason for the higher number of ileal perforation cases in Pakistan could be the circulation of XDR strain of S. Typhi in Karachi.

Management and Outcomes Following Surgery for Gastrointestinal Typhoid: An International, Prospective, Multicentre Cohort Study

BACKGROUND

Gastrointestinal perforation is the most serious complication of typhoid fever, with a high disease burden in low-income countries. Reliable, prospective, contemporary surgical outcome data are scarce in these settings. This study aimed to investigate surgical outcomes following surgery for intestinal typhoid.

METHODS

Two multicentre, international prospective cohort studies of consecutive patients undergoing surgery for gastrointestinal typhoid perforation were conducted. Outcomes were measured at 30 days and included mortality, surgical site infection, organ space infection and reintervention rate. Multilevel logistic regression models were used to adjust for clinically plausible explanatory variables. Effect estimates are expressed as odds ratios (ORs) alongside their corresponding 95% confidence intervals.

RESULTS

A total of 88 patients across the GlobalSurg 1 and GlobalSurg 2 studies were included, from 11 countries. Children comprised 38.6% (34/88) of included patients. Most patients (87/88) had intestinal perforation. The 30-day mortality rate was 9.1% (8/88), which was higher in children (14.7 vs. 5.6%). Surgical site infection was common, at 67.0% (59/88). Organ site infection was common, with 10.2% of patients affected. An ASA grade of III and above was a strong predictor of 30-day post-operative mortality, at the univariable level and following adjustment for explanatory variables (OR 15.82, 95% CI 1.53-163.57, p = 0.021).

CONCLUSIONS

With high mortality and complication rates, outcomes from surgery for intestinal typhoid remain poor. Future studies in this area should focus on sustainable interventions which can reduce perioperative morbidity. At a policy level, improving these outcomes will require both surgical and public health system advances.

Typhoid intestinal perforation in developing countries: Still unavoidable deaths?

Typhoid fever is a public health challenge mostly concentrated in impoverished, overcrowded areas of the developing world, with lack of safe drinking and sanitation. The most serious complication is typhoid intestinal perforation (TIP), observed in 0.8% to 39%, with a striking rate difference between high-income and low-middle-income countries. Although the mortality rate consequent to TIP in resource-poor countries is improved in the last decades, it is still fluctuating from 5% to 80%, due to surgical- and not surgical-related constraints. Huge economic costs and long timelines are required to provide a short- to middle-term solution to the lack of safe water and sanitation. Inherent limitations of the currently available diagnostic tools may lead to under-evaluation as well as over-evaluation of the disease, with consequent delayed treatment or inappropriate, excessive antibiotic use, hence increasing the likelihood of bacterial resistance. There is a need for immunization programs in populations at greatest risk, especially in sub-Saharan Africa. Uniform surgical strategies and guidelines, on the basis of sound or prospective surgical studies and adapted to the local realities, are still lacking. Major drawbacks of the surgical treatment are the frequent delays to surgery, either for late diagnosis or for difficult transports, and the unavailable appropriate intensive care units in most peripheral facilities. As a consequence, poor patient's conditions at presentation, severe peritoneal contamination and unsuitable postoperative care are the foremost determinant of surgical morbidity and mortality.

Acute Physiological and Chronic Health Evaluation II Score and its Correlation with Three Surgical Strategies for Management of Ileal Perforations

INTRODUCTION

Ileal perforation peritonitis is a common surgical emergency in the Indian subcontinent and in tropical countries. It is reported to constitute the fifth common cause of abdominal emergencies due to high incidence of enteric fever and tuberculosis in these management based on Acute Physiological and Chronic Health Evaluation II (APACHE II) score.

METHODS

The following study was conducted in the Department of General Surgery, Government Medical College, Patiala. A total of 57 patients were studied and divided in to Group I, II, and III. APACHE II score accessed and score between 10 and 19 were blindly randomized into three procedures primary closure, resection-anastomosis, and ileostomy. The outcome was compared.

RESULTS

Ileal perforations were most commonly observed in the third and fourth decade of life with male dominance. APACHE II score was accessed and out of total 57 patients, 6 patients had APACHE II score of 0-9, 48 patients had APACHE II score of 10-19, and 3 patients had APACHE II score of ≥20. In APACHE II score 10-19, 15 patients underwent primary closure, 16 patients underwent resection-anastomosis, and 17 patients underwent ileostomy.

DISCUSSION AND CONCLUSION

Primary closure of perforation is advocated in patients with single, small perforation (<1 cm) with APACHE II score 10-19 irrespective of duration of perforation. Ileostomy is advocated in APACHE II score 10-19, where the terminal ileum is grossly inflamed with multiple perforations, large perforations (>1 cm), fecal peritonitis, matted bowel loops, intraoperative evidence of caseating lymph nodes, strictures, and an unhealthy gut due to edema.

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.

Typhoid outbreak in Songkhla, Thailand 2009-2011: clinical outcomes, susceptibility patterns, and reliability of serology tests

Objective

To determine the clinical manifestations and outcomes, the reliability of Salmonella enterica serotype Typhi (S ser. Typhi) IgM and IgG rapid tests, and the susceptibility patterns and the response to treatment during the 2009–2011 typhoid outbreak in Songkhla province in Thailand.

Method

The medical records of children aged <15 years with S ser. Typhi bacteremia were analysed. The efficacy of the typhoid IgM and IgG rapid tests and susceptibility of the S ser. Typhi to the current main antibiotics used for typhoid (amoxicillin, ampicillin, cefotaxime, ceftriaxone, co-trimoxazole, and ciprofloxacin), were evaluated.

Results

S ser. Typhi bacteremia was found in 368 patients, and all isolated strains were susceptible to all 6 antimicrobials tested. Most of the patients were treated with ciprofloxacin for 7–14 days. The median time (IQR) of fever before treatment and duration of fever after treatment were 5 (4, 7) days and 4 (3, 5) days, respectively. Complications of ascites, lower respiratory symptoms, anemia (Hct <30%), and ileal perforation were found in 7, 7, 22, and 1 patients, respectively. None of the patients had recurrent infection or died. The sensitivities of the typhoid IgM and IgG tests were 58.3% and 25.6% respectively, and specificities were 74.1% and 50.5%, respectively.

Conclusion

Most of the patients were diagnosed at an early stage and treated with a good outcome. All S ser. Typhi strains were susceptible to standard first line antibiotic typhoid treatment. The typhoid IgM and IgG rapid tests had low sensitivity and moderate specificity.

Predictors of mortality in children with typhoid ileal perforation in a Nigerian tertiary hospital

PURPOSE

Childhood typhoid ileal perforation is associated with high morbidity and mortality. Our aim was to ascertain the predictors of survival in children.

MATERIALS AND METHODS

This is a tertiary hospital-based retrospective review of patients aged ≤15 years managed for typhoid ileal perforations between January 2005 and December 2013. The details of their biodata, potential risk factors and outcome were evaluated.

RESULTS

Forty-five children out of a total of 97 with typhoid fever had typhoid ileal perforation. The age range was 2-15 years, mean (±SD) = 9.3 (±3.31) years, median = 10 years. There were more males than females (26:19). Thirty-nine (86.7%) patients were >5 years old. There were nine deaths (20% mortality). The mean (±SD) age of survivors was 9.8 (±2.9) years and 7.1 (±4.2) for non-survivors (p = 0.026). The duration of illness at presentation, gender, admission temperature, nutritional status and packed cell volume, perforation-operation interval, number of perforations, surgical procedure, and the duration of surgery did not statistically influence survival (p > 0.05). The age of the patients and burst abdomen attained statistical significance (p < 0.05).

CONCLUSION

The patients' age and postoperative burst abdomen were significant determinants of survival in children with typhoid ileal perforation.

CONCLUSION

The patients' age and postoperative burst abdomen were significant determinants of survival in children with typhoid ileal perforation.

Prevalence, morbidity, and mortality patterns of typhoid ileal perforation as seen at the University of Nigeria Teaching Hospital Enugu Nigeria: an 8-year review

BACKGROUND

Some recent studies have reported a decrease in mortality from typhoid ileal perforation. The present report aims to determine the prevalence, morbidity, and mortality of this disease in patients mostly drawn from a rural area.

METHODS

This is a retrospective study of 50 patients treated between January 1999 and December 2007 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. The variables studied included patient demographics, clinical features, intraoperative findings, complications, and mortality. Statistical analysis was done with SPSS version 13.

RESULTS

Of the 50 patients included in the study, 22 were males with the highest rate in patients aged 20 years and younger. Fever was the commonest symptom and at initial presentation, the mean pulse and respiratory rates were significantly higher in the patients who subsequently died than in those who survived (P < 0.05). All the perforations occurred in the ileum; 62 % of the patients had solitary perforations, 28 % had double perforations, and 10 % had three or more. Fifty-eight perforations were treated by simple closure in two layers, 4 patients had ileal resection and anastomosis, and 2 underwent right hemicolectomy. The mean interval between operation and death was 1.7 days. The overall mortality rate was 30 %, but among those with three or more perforations, mortality was 100 %.

CONCLUSIONS

Typhoid ileal perforation still carries a high mortality especially in rural areas. Those with tachycardia and tachypnea at presentation and those with three or more perforations are at a higher risk of dying from the disease.

Case fatality rate and length of hospital stay among patients with typhoid intestinal perforation in developing countries: a systematic literature review

BACKGROUND

Typhoid fever remains a major health problem in the developing world. Intestinal perforation is a lethal complication and continues to occur in impoverished areas despite advances in preventive and therapeutic strategies.

OBJECTIVES

To estimate the case fatality rate (CFR) and length of hospital stay among patients with typhoid intestinal perforation in developing countries.

DATA SOURCES

Peer-reviewed publications listed in PubMed and Google Scholar.

STUDY ELIGIBILITY

The publications containing data on CFR or length of hospitalization for typhoid fever from low, lower middle and upper middle income countries based on World Bank classification. Limits are English language, human research and publication date from 1st January 1991 to 31st December 2011.

PARTICIPANTS

Subjects with reported typhoid intestinal perforation.

INTERVENTIONS

None, standard practice as reported in the publication.

STUDY APPRAISAL AND SYNTHESIS METHODS

Systematic literature review followed by meta-analysis after regional classification on primary data. Descriptive methods were applied on secondary data.

RESULTS

From 42 published reports, a total of 4,626 hospitalized typhoid intestinal perforation cases and 706 deaths were recorded (CFR = 15·4%; 95% CI; 13·0%-17·8%) with a significant regional differences. The overall mean length of hospitalization for intestinal perforation from 23 studies was 18.4 days (N = 2,542; 95% CI; 15.6-21.1).

LIMITATIONS

Most typhoid intestinal perforation studies featured in this review were from a limited number of countries.

CONCLUSIONS

The CFR estimated in this review is a substantial reduction from the 39.6% reported from a literature review for years 1960 to 1990. Aggressive resuscitation, appropriate antimicrobial coverage, and prompt surgical intervention may have contributed to decrease mortality.

IMPLICATIONS

The quantification of intestinal perforation outcomes and its regional disparities as presented here is valuable in prioritizing and targeting typhoid-preventive interventions to the most affected areas.

Typhoid intestinal perforation: 24 perforations in one patient

Intestine perforation is one of the most dreaded and common complication of typhoid fever remarkably so in developing world; it usually leads to diffuse peritonitis, requiring early surgical intervention. Despite various measures such as safe drinking water supply and safe disposal of waste, intestinal perforation from salmonellosis remains the most common emergency surgery performed. The incidence continues to rise, so also the mortality, despite new antibiotics and improvement in surgical technique. More disturbing is that we now see increasing number of ileal perforations and colonic involvement. We hereby present a case report of 35-year-old male with multiple (24) intestinal perforation in the Ileum and Cecum.

Mortality in typhoid intestinal perforation-a declining trend

BACKGROUND

Typhoid fever is an important public health problem in developing countries. Intestinal perforation is one of the leading fatal complications of typhoid fever. Typhoid perforation occurs more commonly in terminal ileum. Morbidity and Mortality associated with typhoid perforation are high (9-22%). However this study aims to know whether there are any changes of the same.

AIM

To analyse the clinical presentation, management, complications, morbidity and mortality associated with typhoid intestinal perforation and assess changing trends in mortality in typhoid intestinal perforation.

MATERIAL & METHODS

This is a retrospective observational study. Cases regarding the study have been analyzed by reviewing the patient records. It includes 40 patients who were diagnosed with typhoid intestinal perforation, admitted and treated in the Department of General Surgery from February 2011 to January 2012.

RESULTS

A total of 40 patients were considered for the study and their mean age was 35.75 years. 80% of patients were male. Pain abdomen was their main symptom which lasted for an average of 2.95 days. Leukocytosis (11,000 cells/cumm) was present in 57.5% patients. Single perforation was present in 31(77.5%) patients and primary closure was done in 30 of them. Culture sensitivity showed E coli as the main organism. Complications were seen in 42.5% of patients in post-operative period.

CONCLUSION

Early recognition, timely surgical intervention with appropriate surgery and antibiotics, and effective peri-operative care reduces the mortality in typhoid intestinal perforation.

Comparative analysis of primary repair vs resection and anastomosis, with laparostomy, in management of typhoid intestinal perforation: results of a rural hospital in northwestern Benin

Background

Wireless esophageal pH monitoring system is an important approach for diagnosis of gastroesophageal reflux disease (GERD), the aim of this study is to test the tolerability and utility of the first wireless esophageal pH monitoring system made in China, and evaluate whether it is feasible for clinical application to diagnose GERD.

Methods

Thirty patients from Department of Gastroenterology of The First Affiliated Hospital of Chongqing Medical University who were suspected GERD underwent JSPH-1 pH capsule. The capsule was placed 5 cm proximal to the squamocolumnar junction (SCJ) by endoscopic determination, the data was recorded consecutively for 48 hours. Then all pH data was downloaded to a computer for analysis. The discomforts reported by patients were recorded.

Results

30 patients were placed JSPH-1 pH capsule successfully and completed 24-hour data recording, 29 patients completed 48-hour data recording. One patient complained of chest pain and required endoscopic removal. No complications and interference of daily activities were reported during data monitoring or follow-up period. 48-hour pH monitoring detected 15 patients of abnormal acid exposure, on day1 detected 9 patients, the difference had statistical significance (P<0.01). Positive symptom index (SI) was identified in 3 patients with normal pH data in both 24-hours. In total, 48-hour monitoring increased diagnosis of GERD in 9 patients.

Conclusion

48-hour esophageal pH monitoring with JSPH-1 wireless pH monitoring system is safe, well tolerated and effective. It can be feasible for clinical application to diagnose GERD.

Comparative analysis of primary repair vs resection and anastomosis, with laparostomy, in management of typhoid intestinal perforation: results of a rural hospital in northwestern Benin

BACKGROUND

The objective is to compare primary repair vs intestinal resection in cases of intestinal typhoid perforations. In addition, we hypothesised the usefulness of laparostomy for the early diagnosis and treatment of complications.

METHODS

111 patients with acute peritonitis underwent emergency laparotomy: number of perforations, distance of perforations from the ileocaecal valve, and type of surgery performed were recorded. A laparostomy was then created and explored every 48 to 72 hours. The patients were then divided into two groups according to the surgical technique adopted at the initial laparotomy: primary repair (Group A) or intestinal resection with anastomosis (Group B). Clinical data, intraoperative findings, complications and mortality were evaluated and compared for each group.

RESULTS

In 104/111 patients we found intestinal perforations, multiple in 47.1% of patients. 75 had primary repair (Group A) and 26 had intestinal resection with anastomosis (Group B). Group B patients had more perforations than patients in Group A (p = 0.0001). At laparostomy revision, the incidence of anastomotic dehiscence was greater than that of primary repair dehiscence (p = 0.032). The incidence of new perforations was greater in Group B than in Group A (p = 0.01). Group B correlates with a higher morbility and with a higher number of laparostomy revisions than Group A (p = 0.005).

CONCLUSIONS

Resection and anastomosis shows greater morbidity than primary repair. Laparostomy revision makes it possible to rapidly identify new perforations and anastomotic or primary repair dehiscences; although this approach may seem aggressive, the number of operations was greater in patients who had a favourable outcome, and does not correlate with mortality.

Ileal perforation due to typhoid fever - review of operative management and outcome in an urban centre in Nigeria

BACKGROUND

The management of ileal typhoid perforation is a challenging task in our environment. Lack of incidence data base and poor financial resources preclude adequate prevention of this public health menace.

OBJECTIVES

For now the focus will remain the effective and strategic management of this complication to reduce the morbidity and mortality.

METHODS

86 cases of ileal typhoid perforation were seen over a two year period. Most were male children and male young adults. Data collection was by retrieving information from the medical records of Enugu State University of Science and Technology Teaching Hospital (ESUTH). All were resuscitated with 1v fluids, iv antibiotics, nasogastric tube suction and where indicated blood transfusions. Majority had bacteriological, biochemical, haematological and radiological investigations. Laparotomy was undertaken after adequate resuscitation.

RESULTS

Most had been febrile for 2-6weeks prior to admission, with the majority having been labelled resistant malaria cases. Most presented more than 24 h after onset of peritonitis and were therefore explored late, some as late at 96 h. At laparotomy 97% had large volumes of pus and small bowel contents in the peritoneal cavity and 3% had localized intraabdominal abscesses. No attempt at healing or omental localization of the perforation was observed. Fifty two (60.5%) patient underwent simple closure, 18(21%) had ileal resection and enteroanastomosis, 7(8.1%) had tube ileostomy, 5(5.8%) had primary suture and proximal ileo-transverse anastomosis and 4(4.7%) limited right hemicolectomy. All had liberal peritoneal lavage with normal saline. The group that presented relatively early, with minimal pathological changes, had primary suture and mortality in this groups was 11.5%. The group with gross pathological changes seen mainly in patients that presented late had higher mortality rates, even as high as 50%. However our overall mortality rate was 18.6%.

CONCLUSION

The authors affirm that typhoid ileal perforation must be treated surgically. Early presentation and diagnosis, adequate resuscitation, prompt surgery and vigorous post-operative management improved mortality rates. Clearly delays in presentation necessitating prolonged resuscitation and therefore delayed surgery affected mortality.

Spectrum of perforation peritonitis in delhi: 77 cases experience

Perforation peritonitis is the most common surgical emergency encountered by surgeons all over the world as well in India. The spectrum of etiology of perforation peritonitis in tropical countries continues to differ from its western counterpart. This study was conducted at Hindu Rao Hospital, Municipal Corporation of Delhi, New Delhi, India, designed to highlight the spectrum of perforation peritonitis in the eastern countries and to improve its outcome. This prospective study included 77 consecutive patients of perforation peritonitis studied in terms of clinical presentations, causes, site of perforation, surgical treatment, postoperative complications, and mortality at Hindu Rao Hospital, Delhi, from March 1, 2011 to December 1, 2011, over a period of 8 months. All patients were resuscitated and underwent emergency exploratory laparotomy. On laparotomy cause of perforation peritonitis was found and controlled. The most common cause of perforation peritonitis noticed in our series was perforated duodenal ulcer (26.4 %) and ileal typhoid perforation (26.4 %), each followed by small bowel tuberculosis (10.3 %) and stomach perforation (9.2 %), perforation due to acute appendicitis (5 %). The highest number of perforations was seen in ileum (39.1 %), duodenum (26.4 %), stomach (11.5 %), appendix (3.5 %), jejunum (4.6 %), and colon (3.5 %). Overall mortality was 13 %. The spectrum of perforation peritonitis in India continuously differs from western countries. The highest number of perforations was noticed in the upper part of the gastrointestinal tract as compared to the western countries where the perforations seen mostly in the distal part. The most common cause of perforation peritonitis was perforated duodenal ulcer and small bowel typhoid perforation followed by typhoid perforation. Large bowel perforations and malignant perforations were least common in our setup.

Typhoid intestinal perforations at a University teaching hospital in Northwestern Tanzania: A surgical experience of 104 cases in a resource-limited setting

BACKGROUND

Typhoid intestinal perforation is still prevalent in many developing countries. Despite the advances in the management, the outcome in these patients in resource limited countries is still very poor. This study was to review our experiences on the surgical management of typhoid intestinal perforation and to determine the prognostic factors for mortality in our local setting.

METHODS

This was a combined retrospective and prospective study of patients who were operated for typhoid intestinal perforation at Bugando Medical Centre between August 2006 and September 2011. Data collected were analyzed using SPSS computer software version 15.

RESULTS

A total of 104 patients were studied representing 8.7% of typhoid fever cases. Males were affected twice more than the females (2.6:1). Their ages ranged from 8 to 76 years with a median age of 18.5 years. The peak age incidence was in the 11-20 years age group. Fever and abdominal pain were the most common presenting symptoms and majority of the patients (80.8%) perforated between within 14 days of illness. Chest and abdominal radiographs revealed pneumoperitonium in 74.7% of cases. Ultrasound showed free peritoneal collection in 85.7% of cases. Nine (10.2%) patients were HIV positive with a median CD4+ count of 261 cells/μl. The perforation-surgery interval was more than 72 hours in 90(86.5%) patients. The majority of patients (84.6%) had single perforations and ileum was the most common part of the bowel affected occurring in 86.2% of cases. Simple closure of the perforations was the most commonly performed procedure accounting for 78.8% of cases. Postoperative complication rate was 39.4% and surgical site infection was the most frequent complication in 55.5% of cases. Mortality rate was 23.1% and it was statistically significantly associated with delayed presentation, inadequate antibiotic treatment prior to admission, shock on admission, HIV positivity, low CD4 count (< 200 cells/μl), high ASA classes (III-V), delayed operation, multiple perforations, severe peritoneal contamination and presence of postoperative complications (P < 0.001). The median overall length of hospital stay was 28 days.

CONCLUSION

Typhoid intestinal perforation is still endemic in our setting and carries high morbidity and mortality. This study has attempted to determine the factors that statistically influence mortality in typhoid perforation in our environment. Appropriate measures focusing at these factors are vital in order to deliver optimal care for these patients in this region.

Predictor of mortality in children with typhoid intestinal perforation in a Tertiary Hospital in Nigeria

PURPOSE

Typhoid intestinal perforation (TIP) exerts a great toll both on the patients and the surgeons in resource poor countries. Factors that predict mortality in patients with TIP remain controversial. The study aims to determine factors that predict mortality in a Nigerian tertiary facility and to offer strategies for improvement.

MATERIALS AND METHODS

We conducted a retrospective analysis of data of 153 children who underwent surgery for TIP at a Tertiary Hospital in Nigeria over a period of 8 years (January 2002 to December 2009). Data collected included patient demographics, presentation, haemoglobin level (Hgb), presentation-operation interval, type of surgical procedure, nature of peritoneal collection, the number of perforations and duration of surgery. Postoperative complications, duration of hospital stay and outcome were also examined.

RESULTS

There were 99 (64.7%) boys and 54 (35.3%) girls aged 3-15 years, mean (SD) = 9.4 (±3.6) years. There were 105 single perforations and 46 multiple perforations (range 1-32). The surgical procedure was simple 2-layer closure in 128 (83.7%) and segmental resection in 9 (5.9%) children. The mortality was 16 (10.4%). The mean (SD) age of children who survived and those who died was 9.3 (±3.6) years and 10.1 (±4.0) years, respectively; p = 0.446, the mean duration of symptom in children who survived and those who died was 10.3 (±4.9) days and 12.3 (±5.6) days; p = 0.164, and the mean interval between presentation and operation in those who died and those who survived was 29.3 (±25) h and 28.4 (±13.4) h; p = 0.896. Temperature ≥ 38.5°C (p = 0.040), anastomotic leak (p = 0.029) and faecal fistula (p = 0.000) were significantly associated with mortality. Age <5 years (p = 0.675), male gender (p = 0.845), presentation-operation interval ≥24 h (p = 0.940), Hgb less than 8 g/dL (p = 0.058), faeculent peritoneal collection (p = 0.757), number of perforations (p = 0.518) and the surgical technique (p = 0.375) were not related to mortality. Logistic regression analysis showed that only postoperative faecal fistula (p = 0.001; OR = 13.7) independently predicted mortality.

CONCLUSION

Development of postoperative fecal fistula significantly predicted mortality. Prioritizing the prevention of typhoid fever than its treatment and attention to surgical details may significantly reduce mortality of TIP in children in this setting.

Outcome of surgical treatment of intestinal perforation in typhoid fever

AIM: To represent our clinical experience in the treatment of intestinal perforation arising from typhoid fever.

METHODS: The records of 22 surgically-treated patients with typhoid intestinal perforation were evaluated retrospectively.

RESULTS: There were 18 males and 4 females, mean age 37 years (range, 8-64 years). Presenting symptoms were fever, abdominal pain, diarrhea or constipation. Sixteen cases were subjected to segmental resection and end-to-end anastomosis, while 3 cases received 2-layered primary repair following debridement, one case with multiple perforations received 2-layered primary repair and end ileostomy, one case received segmental resection and end-to-end anastomosis followed by an end ileostomy, and one case received segmental resection and end ileostomy with mucous fistula operation. Postoperative morbidity was seen in 5 cases and mortality was found in one case.

CONCLUSION: Intestinal perforation resulting from Salmonella typhi is an important health problem in Eastern and Southeastern Turkey. In management of this illness, early and appropriate surgical intervention is vital.

Risk adjustment is crucial in comparing outcomes of various surgical modalities in patients with ileal perforation

Background

Using crude mortality and morbidity rates for comparing outcomes can be misleading. The aim of the present study was to compare the outcome of various surgical modalities without and with risk adjustment using Physiologic and Operative Severity Scoring for the enUmeration of Mortality and morbidity (POSSUM) score in cases of ileal perforations.

Methods

Prospective study on 125 patients of ileal perforations. Resection anastamosis (Group I) was done in 38 patients, primary repair (Group II) in 42 patients and 45 patients had an ileostomy (Group III). The disease severity was assessed in all patients using POSSUM score. The odds of death without and with risk adjustment using POSSUM mortality score were calculated for all groups

Results

Seventeen patients (14%) patients died and 99 (79%) developed postoperative complications. Using crude mortality rates Group I appeared to be the best treatment option with only 2 (5%) deaths followed by Group II with 5 (12%) deaths where as Group III had the worst outcome with 10 deaths (22%). However, Group III (ileostomy) patients had higher mean POSSUM mortality and morbidity score (55.55%, 91.33%) than Group I (28%, 75.26%) and Group II (27%, 73.59%). Taking Group I as the reference (odds ratio, OR1) odds of death were greatest in Group III (OR 5.14, p = 0.043) followed by Group II (OR 2.43, p = 0.306). With risk adjustment using POSSUM mortality score the odds of death decreased in Group III (OR 1.16 p = 0.875). For the whole group, there was a significant association between the POSSUM score and postoperative complications and deaths. Mean POSSUM mortality and morbidity score of those who died (63.40 vs.33.68, p = 0.001) and developed complications (66.32 vs.84.20, p = 0.001) was significantly higher. For every percent increase in severity score the risk of postoperative complications and death increased by 1.10 (p = 0.001) and1.06 (p = 0.001) respectively.

Conclusion

Despite ileostomy patients having highest crude mortality and complication rates, after risk adjustment it was equally safe. Severity of the disease rather than the surgical option had a significant impact on the outcome in patients with ileal perforations.

Spectrum of perforation peritonitis in Pakistan: 300 cases Eastern experience

Background

Perforation peritonitis is the most common surgical emergency encountered by the surgeons all over the world as well in Pakistan. The spectrum of etiology of perforation peritonitis in tropical countries continues to differ from its western counter part. This study was conducted at Dow University of health sciences and Civil Hospital Karachi (DUHS & CHK) Pakistan, designed to highlight the spectrum of perforation peritonitis in the East and to improve its outcome.

Methods

A prospective study includes three hundred consecutive patients of perforation peritonitis studied in terms of clinical presentations, Causes, site of perforation, surgical treatment, post operative complications and mortality, at (DUHS&CHK) Pakistan, from 1st September 2005 – 1st March 2008, over a period of two and half years. All patients were resuscitated underwent emergency exploratory laparotomy. On laparotomy cause of perforation peritonitis was found and controlled.

Results

The most common cause of perforation peritonitis noticed in our series was acid peptic disease 45%, perforated duodenal ulcer (43.6%) and gastric ulcer 1.3%. followed by small bowel tuberculosis (21%) and typhoid (17%). large bowel perforation due to tuberculosis 5%, malignancy 2.6% and volvulus 0.3%. Perforation due to acute appendicitis (5%). Highest number of perforations has seen in the duodenum 43.6%, ileum37.6%, and colon 8%, appendix 5%, jejunum 3.3%, and stomach 2.3%. Overall mortality was (10.6%).

Conclusion

The spectrum of perforation peritonitis in Pakistan continuously differs from western country. Highest number of perforations noticed in the upper part of the gastrointestinal tract as compared to the western countries where the perforations seen mostly in the distal part. Most common cause of perforation peritonitis is perforated duodenal ulcer, followed by small bowel tuberculosis and typhoid perforation. Majority of the large bowel perforations are also tubercular. Malignant perforations are least common in our setup.

Risk factors affecting morbidity in typhoid enteric perforation

INTRODUCTION

Typhoid enteric perforation is a cause of high morbidity and mortality. This study aim is to determine the factors affecting morbidity in patients with typhoid enteric perforation.

MATERIALS AND METHODS

Ninety-six patients with typhoid enteric perforation were reviewed. The variables are defined as follows: Age, gender, complaints, perforation-operation interval, typhoid fever treatment before the perforation or not, white blood cell (WBC) count, hemoglobin level (Hgb), intraoperative peritonitis intensity, the number of perforations, and type of surgery were examined. To determine the independent risk factors that might affect morbidity in typhoid enteric perforation, we made use of multivariate logistic regression analysis.

RESULTS

Nine variables were applied the univariate analysis, which were greater than 30 years (P = 0.218), male gender (P = 0.02), preoperative treatment (P = 0.147), less than or equal to 48 h perforation-operation interval (P = 0.013), greater than 4,000 K/UL WBC (P = 0.388), less than 8 g/dL Hgb (P = 0.026), greater than 29 Mannheim Peritonitis Index (P < 0.0001), multiple perforation number (P = 0.614), and primary repair (P = 0.105). Logistic regression analysis showed that Mannheim Peritonitis Index (P = 0.014) and perforation-operation interval (P = 0.047) were defined as independent risk factors affecting morbidity.

CONCLUSIONS

If liquid electrolyte, blood, antibiotics, and parenteral nutrition are applied in typhoid enteric perforation cases adequately, then severe peritonitis becomes an independent risk factor that affects morbidity. Early diagnosis and appropriate surgery type would decrease morbidity and mortality.

Typhoid intestinal perforations: twenty-six year experience

BACKGROUND

Typhoid fever (TF) is a severe febrile illness caused by Salmonella typhi. One of the most lethal complications of TF is ileal perforation (TIP). Although the mortality of associated with TIP has decreased slightly over the past decade, it is still high.

METHODS AND RESULTS

The records of the 82 surgically treated patients with TIP were evaluated retrospectively. There were 64 men with the mean age of 36.3 years (range: 7-68 years). In surgical treatment, debridement with primary closure was performed in 32 patients (39.0%), and wedge resection with primary closure was performed in 9 (11. 0%), resection with primary anastomosis in 9 (11.0%), and resection with ileostomy in 32 (39.0%). The most common postoperative complication was wound infection, which occurred in 24 patients (29.3%). The overall morbidity was highest in the ileostomy group. The overall mortality was 11.0% (9 patients). Age, gender, number, and localization of the perforations (p > 0.05) were not found to affect mortality, but prolonged preoperative period (p < 0.001), extended peritoneal contamination (p < 0.01), and ileostomy procedure (p < 0.001) were found to influence the increase in mortality.

CONCLUSIONS

Early and appropriate surgical intervention with effective preoperative and postoperative care may improve survival in TIP.

Typhoid intestinal perforation in children: a continuing scourge in a developing country

Typhoid intestinal perforation is a principal cause of morbidity and mortality affecting both adults and children. This study aims to evaluate the pattern of typhoid intestinal perforation and outcome of its management in Nigerian children. The records of consecutive children managed for typhoid intestinal perforation at Juth, between 1996 and 2005 have been reviewed. There were 184 children (M:F = 1.04:1), with a mean of 5.8 years (range 4 to 15 years). More than a half (62.5%) of the patients were in the 5-6 year age group. The incidence peaked in April-May, and November-December. Increased incidence of typhoid perforation was observed between 2002 and 2005. All patients presented with the classic features of typhoid enteric perforation. Hypokalaemia and anaemia were common at presentation. Only 75 (40.6%) patients had operation within 24 h of perforation. The types of surgery included simple excision of the edges of the peroration and closure (74.5%), wedge resection and closure in (14.5%), segmental resection with primary end-to-end anastomosis (3.6%) and right hemi-colectomy with ileo-colic or ileo-transverse anastomosis. Wound infection and dehiscence, anastomotic breakdown with faecal fistula, intra peritoneal abscesses and chest infections were the main post operative complications. The overall mortality rate was 22.8 (42). Excision and simple closure was associated with the least incidence of anastomotic breakdown and operation time. The incidence of typhoid intestinal perforation is on the increase at our institution. Early limited surgery provides optimal results.
