Laparoscopic repair for perforated peptic ulcer: a randomized controlled trial

Community-based evaluation of laparoscopic versus open simple closure of perforated peptic ulcers

BACKGROUND

Several studies have advocated laparoscopic simple closure (LSC) as the treatment of choice for perforated peptic ulcer disease (PUD). However, there has been no comprehensive community-based evaluation of the advantages of using LSC over open simple closure (OSC). Using an administrative database, we evaluated LSC versus OSC for patients with perforated ulcers.

METHODS

From 6,334 patients with perforated ulcers, we identified 2,909 simple closure cases between 2006 and 2010. Study variables were demographics, mortality, co-morbidities, complications, ulcer location, surgical timing, blood transfusion, postoperative ventilation, operating room (OR) time, time to resumption of oral food intake, length of stay (LOS), and total charges. After matching patient baseline variables between OSC and LSC, we performed multivariate analyses to assess the impacts of LSC on mortality, complications, and ventilation administration.

RESULTS

A total of 2,073 OSC cases and 836 LSC cases were identified in 670 hospitals. Younger age, duodenal ulcer, and pre-existing PUD were indicators for selection of LSC. Matching analysis indicated a correlation between LSC and lower mortality, less frequent postoperative and overall blood transfusion, shorter LOS, earlier return to oral intake, and longer OR time. There was no difference between OSC and LSC in complication rate or mortality. Longer OR time was correlated with a higher complication rate and the need for ventilation, the latter of which was independently associated with an increase in mortality.

CONCLUSIONS

Because longer OR time was associated with more frequent complications and ventilation, surgeons should obtain the skills and strategies necessary to accomplish LSC without extending OR time improperly.

Peritonitis from Perforated Appendicitis: Stress Response after Laparoscopic or Open Treatment

Elevated intra-abdominal pressure during laparoscopy may promote systemic inflammatory response. In patients with generalized peritonitis from perforated appendicitis, we sought to compare acute phase response and immunologic status from laparoscopic and open approach. One hundred and forty-seven consecutive patients underwent appendectomy for perforated appendicitis (73 patients had laparoscopic appendectomy and 74 patients had open appendectomy. Bacteremia, endotoxemia, white blood cells, peripheral lymphocytes subpopulation, human leukocyte antigen-DR (HLA-DR), neutrophil-elastase, interleukin-1 and 6 (IL-1 and 6), and C-reactive protein were investigated. One hour after intervention, bacteremia was significantly higher in the open group compared with the laparoscopic group ( P < 0.05). A significantly higher concentration of systemic endotoxin was detected intraoperatively in the open group of patients in comparison with the laparoscopic group ( P < 0.05). Laparotomy caused a significant increase in neutrophil concentration, neutrophil-elastase, IL-1 and 6, and C-reactive protein and a decrease of HLA-DR. We recorded 6 cases (8.1%) of intra-abdominal abscess in the open group and one (1.3%) in the laparoscopic group ( P < 0.05). Open appendectomy, in case of peritonitis, increased the incidence of bacteremia, endotoxemia, and systemic inflammation compared with laparoscopic appendectomy. Early enhanced postoperative systemic inflammation may cause lower transient immunologic defense after laparotomy (decrease of HLA-DR), leading to enhanced sepsis in these patients.

Analysis of risk factors for postoperative morbidity in perforated peptic ulcer

Purpose

Emergency operations for perforated peptic ulcer are associated with a high incidence of postoperative complications. While several studies have investigated the impact of perioperative risk factors and underlying diseases on the postoperative morbidity after abdominal surgery, only a few have analyzed their role in perforated peptic ulcer disease. The purpose of this study was to determine any possible associations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer.

Materials and Methods

In total, 142 consecutive patients, who underwent surgery for perforated peptic ulcer, at a single institution, between January 2005 and October 2010 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively.

Results

The postoperative morbidity rate associated with perforated peptic ulcer operations was 36.6% (52/142). Univariate analysis revealed that a long operating time, the open surgical method, age (≥60), sex (female), high American Society of Anesthesiologists (ASA) score and presence of preoperative shock were significant perioperative risk factors for postoperative morbidity. Significant comorbid risk factors included hypertension, diabetes mellitus and pulmonary disease. Multivariate analysis revealed a long operating time, the open surgical method, high ASA score and the presence of preoperative shock were all independent risk factors for the postoperative morbidity in perforated peptic ulcer.

Conclusions

A high ASA score, preoperative shock, open surgery and long operating time of more than 150 minutes are high risk factors for morbidity. However, there is no association between postoperative morbidity and comorbid disease in patients with a perforated peptic ulcer.

Perforated duodenal ulcer associated with anterior abdominal abscess: A case report

Computed tomography (CT) has been regarded as the method of choice for detecting the presence, site and cause of gastrointestinal tract perforation. In addition to determining the presence of perforation, CT can also localise the perforation size and demonstrate direct and indirect findings relative to the perforation. In this case study, we report the CT results in a patient with perforated duodenal ulcer associated with anterior abdominal abscess, and highlight the diagnostic value of CT imaging.

Minilaparotomy for perforated duodenal ulcer

The usefulness of the minilaparotomy approach for perforated duodenal ulcer repair was retrospectively evaluated in 37 patients (26 men; mean age, 56.5 years). Simple closure with an omental patch by minilaparotomy (skin incision, < or = 7 cm) was successful in 86.5% of the cases, with an operative mortality of 2.7%. Compared with the results in historic control patients who underwent conventional open surgery (n = 27), a shorter operative time (P < 0.01), lower frequency of analgesic use (P = 0.03), earlier passage of flatus (P < 0.01), and shorter hospital stay (P = 0.04) were obtained in the patients undergoing minilapartomoy. The postoperative morbidity was identical between the two groups (16.2% versus 33.3%, P = 0.40). On multivariate analysis, a large amount of intraabdominal fluid was the only significant risk factor for extension of the minilaparotomy wound (P = 0.012). The minilaparotomy approach appears to be a feasible, safe, and less invasive approach compared with the conventional open approach and could be a useful alternative to the laparoscopic approach in selected patients with perforated duodenal ulcer.

Laparoscopic simple closure alone is adequate for low risk patients with perforated peptic ulcer

BACKGROUND

Helicobacter pylori (H.P.) eradication has led to a significant decline in peptic ulcer prevalence; however, the number of patients requiring surgical intervention remains relatively unchanged. Laparoscopy suture repair is the most commonly used procedure for perforated peptic ulcer (PPU). Whether omental patch adds any benefit than simple closure alone is not answered.

METHODS

From July 2007 to August 2010, patients received emergency surgeries for PPU in our department were enrolled in this study. The demographic data, disease pattern, surgical outcomes were retrospectively collected. Patients who had previous multiple operations, with profound shock, and complicated ulcers were excluded.

RESULTS

Totally 73 patients were enrolled. 26 of them received simple closure and the other 47 received simple closure plus an omental patch. There were no difference in age, gender, ASA, Boey risk score, and incidence of co-morbidities. The Mannheim Peritonitis index, median operation time and length of stay were not different between groups.

CONCLUSIONS

In terms of leakage rate and surgical outcome, the maneuver to cover an omental patch on the repaired PPU did not show additional advantages compared to simple closure alone. Further prospective randomized study is required to clarify the safety and feasibility of simple closure alone without buttressing an omentum patch.

Management of perforated peptic ulcer in a district general hospital

INTRODUCTION

Laparoscopic surgery has become increasingly popular for elective surgery but it has gained slow transference to emergency surgery. The management of perforated peptic ulcers (PPU) laparoscopically is an accepted strategy yet it still remains infrequently used. The purpose of this study was to analyse the utility and outcomes of laparoscopy versus open repair for PPU in a district general hospital. In addition, we evaluated whether the subspecialty of the on-call consultant affected the method of repair performed and the training opportunities for trainee surgeons.

METHODS

Between 2003 and 2009, 53 patients underwent laparoscopic repair, 89 patients underwent open repair and a further 20 patients had laparoscopic repair that was converted to open repair for PPU. The results from a prospectively compiled database were analysed with primary outcome measures including operative time, length of hospital stay and mortality.

RESULTS

The median operating time in the laparoscopic group was 60.0 minutes compared with 50.5 minutes in the open group. Hospital stay in surviving patients was significantly shorter in patients treated completely laparoscopically (5 days) when compared with the open group (6 days) ( p <0.01). There were six deaths in the laparoscopic group (11%) compared with 13 in the open group (15%) and one in the converted group (5%). Trainees performed 53% (47/89) of open repairs and 13% (7/54) of laparoscopic repairs.

CONCLUSIONS

Both laparoscopic and open repair are equally safe in the management of PPU. Our findings support the view that this procedure can be successfully used as a training operation.

Emergency ulcer surgery

The rate of elective surgery for peptic ulcer disease has been declining steadily over the past 3 decades. During this same period, the rate of emergency ulcer surgery rose by 44%. This means that the gastrointestinal surgeon is likely to be called on to manage the emergent complications of peptic ulcer disease without substantial experience in elective peptic ulcer disease surgery. The goal of this review is to familiarize surgeons with our evolving understanding of the pathogenesis, epidemiology, presentation, and management of peptic ulcer disease in the emergency setting, with a focus on peptic ulcer disease-associated bleeding and perforation.

Transumbilical single-access laparoscopic perforated gastric ulcer repair

INTRODUCTION

In patients presenting with peritonitis, laparoscopy offers the possibility of diagnosis as well as treatment, with less abdominal trauma, reduced postoperative pain, and shorter hospital stay.

CASE REPORT

A 30-year-old woman, presenting with diffuse abdominal pain and free pneumoperitoneum, was submitted to transumbilical single-access laparoscopy. The procedure was performed using a standard 11-mm reusable trocar in the umbilicus and curved reusable instruments inserted transumbilically without trocars. The cavity exploration showed a perforated gastric ulcer at the anterior surface of the prepyloric area. A gastric suture repair, omentoplasty, and lavage of the cavity were performed.

RESULTS

The umbilical incision was 15 mm and laparoscopy lasted 86 minutes. Use of painkillers was minimal, and the patient was discharged on the fifth postoperative day. After 6 months, the umbilical scar was no visible.

CONCLUSIONS

Transumbilical single-access laparoscopy can be proposed in selected patients presenting perforated gastric ulcer, with the main advantage of improved cosmetic results.

Reappraising the surgical approach on the perforated gastroduodenal ulcer: should gastric resection be abandoned?

Background

Advancements in medical care for peptic ulcer disease (PUD) have reduced the need for invasive surgical procedures such as gastric resection (GR). Community-based PUD studies from a large sampling of PUD patients designed to analyze hospital resource use and outcomes after different surgical procedures have been rare. We aimed to exhaustively reappraise the risk factors and patient demographics that affect PUD patient recoveries after GR compared to those after simple closure (SC).

Methods

We used a Japanese administrative database for 6 consecutive months each year between 2006 and 2010. The database included a total of 68,432 PUD patients; we analyzed 6,334 perforation cases and 3,148 cases of patients who underwent GR or SC. Study variables were demographics, comorbidities, characteristics of PUD, and operative day. Study outcomes that were analyzed included mortality, postoperative complications, ventilation administration, postoperative blood transfusions, length of stay, total charges, operating room (OR) time, and the postoperative fasting period (defined as the day of surgery to the day oral food intake was resumed.) To reduce selection bias in study procedures and to control the variation in hospital practice, a propensity score (PS) matching cohort analysis and a mixed linear regression model were used to assess the effects of GR on the outcomes.

Results

In 699 hospitals, 322 GRs and 2,826 SCs were observed. Younger age, duodenal ulcers, preexisting anemia and an operative day no more than 24hours were significant associated with the choice of SCs. No significant differences were observed in study outcomes after either GR or SC; more postoperative blood transfusions and longer OR times but shorter postoperative fasting periods were observed after GR. Longer OR times, ventilation and postoperative blood transfusion were significantly associated with mortality. Not GR but longer OR times use of ventilation and complications were the most significant indicators of increased resource use.

Conclusions

There were no major significant differences in GR when compared to SC with regards to patient recoveries. Surgeons should obtain the skills and establish strategies to optimize either type of surgical procedure including minimizing OR time and establishing the best perioperative critical care.

Assessing the invasiveness of NOTES perforated viscus repair: a comparative study of NOTES and laparoscopy

BACKGROUND

Natural orifice transluminal endoscopic surgery (NOTES) repair of perforated peptic ulcers may decrease surgical invasiveness and improve patient outcomes.

METHODS

Full thickness gastrotomy was created laparoscopically in swine followed by soilage time. Repair proceeded with a laparoscopic (n = 14) or the NOTES (n = 14) approach. For NOTES repair, the omentum was endoscopically pulled into the gastric lumen and clipped. Intraoperative and postoperative parameters were recorded, including arterial blood gas (ABG) analysis and serum samples for white blood cell (WBC), TNF-α, IL-1, and IL-6 analysis.

RESULTS

Twenty-four of 28 animals thrived to study completion. NOTES repair could not be accomplished in one animal. At necropsy, all repairs were intact. Blood pressure was equivalent between groups. Pulse examined during the last 30 min of each procedure revealed a slightly higher mean pulse in the animals undergoing NOTES procedures (NOTES, 102 ± 28; laparoscopy, 83 ± 24). ABG obtained at the conclusion of the procedure revealed a pH of 7.47 in NOTES animals and 7.43 in the laparoscopy animals (p = 0.06), a change from baseline in both groups. The final pCO(2) was lower in the NOTES group (NOTES, 40.62; laparoscopy, 47.49, p = 0.03). WBC counts were comparable on postoperative day (POD) 1 (NOTES, 21.1; laparoscopy, 19.0; p = 0.49). Mean TNF-α serum levels were equivalent at all time points between groups; however, TNF-α varied significantly from baseline to POD 7 (p = 0.002).

CONCLUSION

NOTES omental repair appears comparable to that of laparoscopy. The lower arterial pCO(2) at the conclusion of the NOTES procedure may be advantageous in critically ill patients.

Incidence of perforated gastrojejunal anastomotic ulcers after laparoscopic gastric bypass for morbid obesity and role of laparoscopy in their management

BACKGROUND

Laparoscopic Roux-en-Y gastric bypass (RYGB) is a well-established procedure to treat morbid obesity. Gastrojejunal anastomotic (GJA) ulcers can develop after surgery with subsequent perforation. Our aim was to evaluate the incidence, presentation and outcome of management of perforated GJA ulcer disease after laparoscopic RYGB.

METHODS

The database of all patients at the senior author's bariatric institutions was retrospectively reviewed. The results are presented as mean (range).

RESULTS

From April 2002 to April 2010, 1213 patients underwent laparoscopic RYGB, which included 1184 primary and 29 revision procedures. The operative mortality was .15%. Ten patients developed perforated GJA ulcers (.82%) at a mean of 13.5 (6-19) months. The patients who presented to bariatric surgeons (n = 5) were treated with laparoscopic closure and an omental patch, and those who presented to nonbariatric surgeons (n = 5) were treated with laparotomy. The morbidity and mortality rate was 30% and 10%, respectively, and the mean postoperative hospital stay for the survivors was 14 (5-44) days.

CONCLUSION

Perforated GJA ulcers can develop in 1 of 120 patients after laparoscopic RYGB and can be effectively managed by laparoscopic repair with an omental patch, if expertise is available.

WSES consensus conference: Guidelines for first-line management of intra-abdominal infections

Intra-abdominal infections are still associated with high rate of morbidity and mortality.A multidisciplinary approach to the management of patients with intra-abdominal infections may be an important factor in the quality of care. The presence of a team of health professionals from various disciplines, working in concert, may improve efficiency, outcome, and the cost of care.A World Society of Emergency Surgery (WSES) Consensus Conference was held in Bologna on July 2010, during the 1st congress of the WSES, involving surgeons, infectious disease specialists, pharmacologists, radiologists and intensivists with the goal of defining recommendations for the early management of intra-abdominal infections.This document represents the executive summary of the final guidelines approved by the consensus conference.

The role of laparoscopic approach for anastomotic leakage after minimally invasive surgery for colorectal cancer

OBJECTIVES

The objectives of this study were to evaluate the feasibility and safety of a re-laparoscopic approach to manage anastomotic leakage after minimally invasive colorectal resection and to compare its clinical outcomes with those obtained using an open approach.

METHODS

We retrospectively reviewed clinical data from 1714 patients who underwent colorectal cancer resection from September 2006 to August 2009 at the Korea University Medical Center. Clinical data from a total of 57 surgery patients who developed anastomotic leakage were analyzed.

RESULTS

Twenty-six leakage cases were managed laparoscopically, whereas the remaining 31 leakage cases were managed using an open approach. There were no significant differences in age, sex, or other clinical features between patients in the two groups. The total operation time was shorter in the laparoscopic group (107.3 ± 68.1 minutes) than in the open group (126.5 ± 50.1 minutes), but this difference was not statistically significant (P = .230). Six cases in each group required additional procedures such as reoperation or percutaneous intervention (P = .126). There was one case of postoperative mortality in the open group. Median (quartiles 25%-75%) number of days required to resume a soft diet tended to be shorter in the laparoscopic group than the open group (5 [3-7] versus 6 [5-10] days; P = .057). Patients in both groups showed similar postoperative complications including intraabdominal abscess; however, the incidence of wound infection was significantly lower in the laparoscopic group than the open group (3.8% versus 25.8%; P = .031).

CONCLUSIONS

Compared with conventional open treatment of anastomotic leakage, the laparoscopic approach resulted in fewer wound complications and tendency of early recovery of bowel movement without an increase in adverse outcomes. Using a laparoscopic approach, all the advantages of minimally invasive surgery can be realized in patients who develop anastomotic leakage after minimally invasive surgery.

Laparoscopic repair of perforated ulcer in Western Denmark - a retrospective study

OBJECTIVE

to report the distribution and results of laparoscopic repair of perforated ulcer surgery in surgical departments in a major region in Denmark and compare it with the results from the national database regarding mortality and morbidity.

METHOD

case charts from all patients who underwent laparoscopic repair of perforated ulcer in Western Denmark in the period 1 January 2003 - 1 July 2007 were collected. Demographical data, surgical details, morbidity, 30-day mortality, and length of stay were recorded. For comparison, data from the National Health Registry (NIP) describing all patients who had an operation due to perforated ulcer in this period was obtained.

RESULTS

no more than 51 out of 818 patients undergoing operation for perforated ulcer in the region had a laparoscopic operation. Mortality in the laparoscopic group was 4% compared to 26% reported from the national database (NIP). The laparoscopic group had a higher reperforation rate but length of stay was equal. No formal criteria concerning surgeon or patients selection for laparoscopic surgery were met.

CONCLUSION

laparoscopic repair of perforated ulcer was done without any selection criteria in few surgical departments in Western Denmark and was associated with a low mortality but a higher risk of reperforation.

Laparoscopy in the emergency setting: a retrospective review of 540 patients with acute abdominal pain

BACKGROUND

Laparoscopy has been widely accepted among surgeons for the diagnosis and management of acute abdominal conditions. In this study, we aim to evaluate and summarize the experience in laparoscopic procedures, both diagnostic and interventional, for emergency nontraumatic abdominal conditions, in a tertiary academic center.

METHODS

From June 2005 to June 2009, a total of 1414 patients were subjected to a variety of emergency procedures at the university hospital of Patras and 540 of these patients were managed laparoscopically (38.2%). Indications for operations in the laparoscopic group were abdominal pain mimicking appendicitis in 229 patients (42.4%), acute cholecystitis in 248 patients (45.9%), gastroduodenal perforated ulcer in 14 patients (2.6%), small bowel obstruction in 24 patients (4.4%), and nonspecific abdominal pain in 25 patients (4.6%).

RESULTS

Diagnosis was established in 530 patients (98.2%) and definitive laparoscopic treatment was offered to 514 patients (95.2%). The conversion rate was 2.2%. Total mortality was 1.1% and total morbidity was 7.9%.

CONCLUSIONS

Laparoscopic approach to abdominal emergency provides high diagnostic accuracy and therapeutic options. Surgical experience, optimal procedural timing, and appropriate patient selection criteria diminish perioperative mortality and morbidity, and are associated with nominal conversion.

Laparoscopic correction of perforated peptic ulcer: first choice? A review of literature

BACKGROUND

Perforated peptic ulcer (PPU), despite antiulcer medication and Helicobacter eradication, is still the most common indication for emergency gastric surgery associated with high morbidity and mortality. Outcome might be improved by performing this procedure laparoscopically, but there is no consensus on whether the benefits of laparoscopic closure of perforated peptic ulcer outweigh the disadvantages such as prolonged surgery time and greater expense.

METHODS

An electronic literature search was done by using PubMed and EMBASE databases. Relevant papers written between January 1989 and May 2009 were selected and scored according to Effective Public Health Practice Project guidelines.

RESULTS

Data were extracted from 56 papers, as summarized in Tables 1-7. The overall conversion rate for laparoscopic correction of perforated peptic ulcer was 12.4%, with main reason for conversion being the diameter of perforation. Patients presenting with PPU were predominantly men (79%), with an average age of 48 years. One-third had a history of peptic ulcer disease, and one-fifth took nonsteroidal anti-inflammatory drugs (NSAIDs). Only 7% presented with shock at admission. There seems to be no consensus on the perfect setup for surgery and/or operating technique. In the laparoscopic groups, operating time was significant longer and incidence of recurrent leakage at the repair site was higher. Nonetheless there was significant less postoperative pain, lower morbidity, less mortality, and shorter hospital stay.

CONCLUSION

There are good arguments that laparoscopic correction of PPU should be first treatment of choice. A Boey score of 3, age over 70 years, and symptoms persisting longer than 24 h are associated with higher morbidity and mortality and should be considered contraindications for laparoscopic intervention.

Laparoscopy in Non-Trauma Abdominal Emergencies

The role for laparoscopy has evolved throughout the years and more evidence has become available to support its use in abdominal emergencies. Although the literature has expanded and more randomized controlled trials are available, skepticism persists concerning the use of laparoscopy in emergency situations. We attempt to provide the readers with a concise review and highlight the most relevant issues and available evidence in seven different non-trauma abdominal emergencies.

Natural orifice translumenal endoscopic surgery used for perforated viscus repair is feasible using lower peritoneal pressures than laparoscopy in a porcine model

BACKGROUND

Procedure-related complications contribute to 1-year mortality in patients with perforated ulcers. Natural orifice translumenal endoscopic surgery (NOTES) might offer a new repair approach.

STUDY DESIGN

Swine were randomized to laparoscopic or NOTES repair. Laparoscopic gastrotomy creation (1 cm) was followed by 4 hours soilage time. After peritoneal cavity irrigation (per group assignment), repair proceeded with a laparoscopic or NOTES approach. For NOTES repair, omentum was endoscopically grasped, pulled into the gastric lumen, and fixed with metallic clips. Feasibility; time to complete procedures; pneumoperitoneal pressures; and clinical parameters, including necropsy and peritoneal culture at 2 weeks, were recorded.

RESULTS

NOTES repair failed in 1 animal (technical); repair was completed laparoscopically, and data were analyzed as intention to treat. Specific NOTES repair time (minutes) was comparable with laparoscopy (36 versus 46; p = 0.2). Mean abdominal pressure (mmHg) required to complete NOTES repair was lower than in laparoscopy (4 versus 12; p < 0.001). Nineteen of 23 animals thrived until necropsy at 2 weeks. Three animals succumbed to airway compromise in recovery; 1 NOTES animal failed to thrive on postoperative day 7. No intra-abdominal cause for these deaths was found. At necropsy all repairs were intact, and peritoneal cultures revealed a small and equivalent amount of colony-forming units in each group.

CONCLUSIONS

Endoscopic ulcer repair appears technically feasible with similar clinical and infectious outcomes to laparoscopy. The lower required pneumoperitoneal pressures used in these NOTES techniques are recognizable different outcomes from laparoscopy and can be advantageous in critically ill patients.

A 3 cm sealed pyloric perforation discovered during emergency cholecystectomy

The diagnosis of acute cholecystitis is made on clinical, haematological, biochemical and radiological grounds, and laparoscopic cholecystectomy is commonly performed in the emergency setting. We report a case in which a patient diagnosed with acute cholecystitis was found to have a sealed pyloric perforation at laparoscopy as well as cholecystitis.

64-Slice multidetector computed tomography evaluation of gastrointestinal tract perforation site: detectability of direct findings in upper and lower GI tract

OBJECTIVE

To evaluate wall discontinuity, as observed using 64-slice multidetector-row computed tomography (64-MDCT), as a direct finding (DF) indicating the perforation site in patients with gastrointestinal (GI) tract perforations.

METHODS

We retrospectively studied 41 consecutive patients presenting with acute abdomen and exhibiting extraluminal air (EA) on 64-MDCT. Three readers evaluated the distribution of EA, extraluminal faeces, dirty mass, dirty fat sign, extraluminal fluid collection and bowel wall thickening (i.e. conventional findings, CFs) as well as DFs.

RESULTS

Twenty-two cases were surgically or endoscopically confirmed to have upper GI tract perforations, and 19 had lower GI tract perforations. The DFs correctly identified the sites of perforation in 80.5% of patients when 2-mm-thick imaging slices were used. For the detection of upper GI tract perforations, the sensitivity, specificity and accuracy were 95.5%, 94.7% and 95.1% for the DFs and 50.0%, 100% and 73.2% for the CFs, respectively. Significant differences in sensitivity (p < 0.001) and diagnostic accuracy (p < 0.05) were observed between the DFs and CFs for upper GI perforations but not for lower GI tract perforations.

CONCLUSION

DFs of the perforation site by using 64-MDCT were more sensitive and accurate than CFs for the detection of upper GI tract perforations.

Perforated peptic ulcer: different ethnic, climatic and fasting risk factors for morbidity in Al-ain medical district, United Arab Emirates

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.

Laparoscopic repair for perforated peptic ulcers with U-CLIP(R)

Background

The literature established that, in patients without Boey's risk factors, laparoscopic repair of perforated peptic ulcers, compared to open repair, is associated to lower wound infection rate, less analgesic use, reduction in post operative pain, shorter hospital stay. Some of the main drawbacks are length of operative time and laparoscopic surgeon's experience in intracorporeal knotting.

We, for first, report our preliminary experience of perforated peptic ulcers' laparoscopic repair using Medtronic U-Clip^®.

Methods

From January 2008 to June 2008 we performed laparoscopic repair of perforated peptic ulcers using Medtronic U-Clip^® in 10 consecutive patients (6 men and 4 women, from 20 to 65 years-old of age). All the patients presented with iuxtapyloric perforated peptic ulcer, not greater than 10 mm, without signs of sepsis, free from major illnesses. The mini-invasive procedure was performed both by skilled and non-skilled laparoscopic surgeons under experts' surveillance. After it was recognized, perforation was sutured using U-Clip^® in a full-thickness manner.

Results and Discussion

We reported no surgical complications in the peri-operative period. The clinical outcome and time needed to perform the intervention didn't change between skilled and non-skilled surgeons. The follow-up at 30 days was good.

Conclusion

In our experience, the anastomotic device U-Clip^® simplifies laparoscopic repair of perforated peptic ulcer, avoiding the need to perform knots and making the procedure safe and easier.

Randomized clinical trial of laparoscopic versus open repair of the perforated peptic ulcer: the LAMA Trial

BACKGROUND

Laparoscopic surgery has become popular during the last decade, mainly because it is associated with fewer postoperative complications than the conventional open approach. It remains unclear, however, if this benefit is observed after laparoscopic correction of perforated peptic ulcer (PPU). The goal of the present study was to evaluate whether laparoscopic closure of a PPU is as safe as conventional open correction.

METHODS

The study was based on a randomized controlled trial in which nine medical centers from the Netherlands participated. A total of 109 patients with symptoms of PPU and evidence of air under the diaphragm were scheduled to receive a PPU repair. After exclusion of 8 patients during the operation, outcomes were analyzed for laparotomy (n = 49) and for the laparoscopic procedure (n = 52).

RESULTS

Operating time in the laparoscopy group was significantly longer than in the open group (75 min versus 50 min). Differences regarding postoperative dosage of opiates and the visual analog scale (VAS) for pain scoring system were in favor of the laparoscopic procedure. The VAS score on postoperative days 1, 3, and 7 was significant lower (P < 0.05) in the laparoscopic group. Complications were equally distributed. Hospital stay was also comparable: 6.5 days in the laparoscopic group versus 8.0 days in the open group (P = 0.235).

CONCLUSIONS

Laparoscopic repair of PPU is a safe procedure compared with open repair. The results considering postoperative pain favor the laparoscopic procedure.

Refractory peptic ulcer disease

Refractory PUD is a diagnostic and therapeutic challenge. Optimal management of severe or refractory PUD requires a multidisciplinary team approach, using primary care providers, gastroenterologists, and general surgeons. Medical management has become the cornerstone of therapy. Identification and eradication of H pylori infection combined with acid reduction regimens can heal ulceration and also prevent recurrence. Severe, intractable or recurrent PUD and associated complications mandates a careful and methodical evaluation and management strategy to determine the potential etiologies and necessary treatment (medical or surgical) required.

Operative risks of digestive surgery in cirrhotic patients

Digestive surgery in cirrhotic patients has long been limited to the treatment of disorders related to the liver disease (portal hypertension, hepatocellular carcinoma and umbilical hernia). The improvement in cirrhotic patient management has allowed an increase in surgical procedures for extrahepatic indications. The aim of this study was to evaluate the operative risks of such surgical procedures. Extrahepatic surgery in cirrhotic patients is associated with high mortality and morbidity. Emergency surgery, gastrointestinal tract opening (esophagus, stomach and colon), <30 g/L serum albumin, transaminase levels more than three times the upper limit of normal, ascites, and intraoperative transfusions are the main risk factors for postoperative death. In Child A patients, the operative risk of elective surgery is moderate and surgical indications are not altered by the presence of cirrhosis. The laparoscopic approach should be recommended because of the potentially lower morbidity. In Child C patients, operative mortality is often higher than 40%; surgical indications must remain exceptional and non operative management has to be preferred. In Child B patients, preoperative improvement of liver function is mandatory for lower risk surgery.

Comparison between open and laparoscopic repair of perforated peptic ulcer disease

BACKGROUND

The place of laparoscopic repair of perforated peptic ulcer followed by peritoneal toilet has been established, although it is not routinely practiced. This prospective study compared laparoscopic and open repair of perforated peptic ulcer disease. We evaluated whether the early results from laparoscopic repair resulted in improved patient outcome compared with conventional open repair.

METHODS

All patients who underwent repair of perforated peptic ulcer disease during a 12-month period in our unit were included in the study. The primary end points that were evaluated were total operative time, nasogastric tube utilisation, intravenous fluid requirement, total time of urinary catheter and abdominal drainage usage, time taken to return to normal diet, intravenous/intramuscular opiate use, time to full mobilization, and total in-patient hospital stay.

RESULTS

Thirty-three patients underwent surgical repair of perforated peptic ulcer disease (19 laparoscopic repairs and 14 open repairs; mean age, 54.2 (range, 32-82) years). There was no increase in total operative time in patients who had undergone laparoscopic repair (mean: 61 minutes laparoscopic versus 57 minutes open). There was significantly less requirement for intravenous/intramuscular opiate analgesia in patients who had undergone laparoscopic repair (mean time to oral analgesia: 1.2 days laparoscopic versus 3.8 days open). In addition there was a significant decrease in the time that the nasogastric tube (mean: 2.1 days laparoscopic versus 3.1 days open), urinary catheter (mean: 2.3 days laparoscopic versus 3.7 days open) and abdominal drain (mean: 2.2 days laparoscopic versus 3.8 days open) were required during the postoperative period. Patients who had undergone laparoscopic repair required less intravenous fluids (mean: 1.4 days laparoscopic versus 3.1 days open) and returned to normal diet (mean: 2.3 days laparoscopic versus 4.8 days open) and full mobilization significantly earlier than those who had undergone open repair (mean: 2.3 days laparoscopic versus 3.3 days open). In addition, patients who had undergone laparoscopic repair required a shorter in-patient hospital stay (mean: 3.1 days laparoscopic versus 4.3 days open).

CONCLUSIONS

Laparoscopic repair is a viable and safe surgical option for patients with perforated peptic ulcer disease and should be considered for all patients, providing that the necessary expertise is available.

The efficacy of laparoscopic surgery in patients with peritonitis

BACKGROUND

Laparoscopy is an essential part of our armamentarium in certain conditions and has been recently begun to be used on acute abdominal peritonitis effectively and frequently by surgeons. But, there is still a debate on laparoscopic management of surgical emergencies. The aim of the current study is to evaluate the safety and efficiency of laparoscopy and its role in patients with acute abdominal emergencies retrospectively.

MATERIALS AND METHODS

From May 2002 to May 2006, 147 patients with provisional diagnosis of acute abdomen were operated laparoscopically (68 suspected lower quadrant peritonitis, 17 gastroduodenal perforated ulcers, and 62 cholecystitis).

RESULTS

A definitive diagnosis was accomplished in 93.1% (137 patients) of the cases and 85.7% (126) of the patients were successfully treated by emergent laparoscopy. An unnecessary laparotomy was avoided in 17.0% (24 women and 1 man) of the patients. The conversion rate was 14.2%. The morbidity rate was 4.0% with a postoperative mortality rate of 0.68%. After a mean period of 16.2 months, postoperative evolutions of patients were satisfactory.

CONCLUSIONS

Laparoscopic surgery, with high diagnostic accuracy and therapeutic capabilities, can be safely and effectively applied to the patients with acute abdominal emergencies in experienced hands. We believe that laparoscopy is a valuable way to prevent unnecessary laparotomies when routine investigations fail to identify the cause. This technique can be widely used in abdominal emergencies with increasing experience, but further studies are required to definitively establish its role in acute abdominal disorders.

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.

Ten-Year Retrospective Comparative Analysis of Laparoscopic Repair versus Open Closure of Perforated

BACKGROUND

Aim of this study was to compare the result of open and laparoscopic repair of perforated peptic ulcers in terms of operation time, postoperative pain, hospital stay, and wound infection.

METHODS

Clinical notes of 152 patients who underwent the operative closure of perforated peptic ulcers from 1996 to 2006 were available for study. All patients were offered laparoscopic approach from 1998 onward. Repair was done using omentum patch. Open approach was used in 57 patients and laparoscopic in 95 patients. Results were analyzed in terms of requirement of analgesia, hospital stay, return to work, complications, and mortality.

RESULTS

Closure was successful in all cases using omentum patch. There was no conversion to open in laparoscopic group. The mean operation time was less in laparoscopic versus open (P<0.001). The mean number of analgesic injection given were 3 and the hospital stay was 4 days in laparoscopy, the corresponding figure in laparotomy were 6 and 9 respectively (P<0.001). Total numbers of complication in laparoscopic repair were 9 compared to 35 in open (P=0.011). Two patients died in each group. Incidental significant incidences of perforations was observed in men (P<0.001), fasting during Ramadan (P<0.001), smokers (P<0.001), past history of peptic ulcer disease (P=0.007), and use of non-steroidal anti-inflammatory drugs (P=0.035).

CONCLUSION

Compared to open approach, laparoscopic repair required shorter operation time, lesser analgesia, had fewer complications, shorter hospital stays and early return to work.

Laparoscopic repair of peptic ulcer perforation without omental patch versus conventional open repair

BACKGROUND

Laparoscopic surgery, a minimally invasive technique, has recently begun to be used on perforated peptic ulcers effectively and frequently. Nevertheless, most studies have shown that the disadvantages of the laparoscopic treatment of peptic ulcers are a long operation time, a high reoperation rate, and a need for an experienced surgeon. Thus, the objective of the current study was to compare the safety and efficacy of optimized laparoscopic surgery without an omental patch for a perforated peptic ulcer within a shorter operational time with conventional open surgery in a 4-year period.

PATIENTS AND METHODS

From May 2002 to June 2006, 35 consecutive patients with a clinical diagnosis of a perforated peptic ulcer were prepared prospectively to undergo either an open or optimized laparoscopic surgery.

RESULTS

Seventeen patients with a perforated peptic ulcer underwent simple laparoscopic repair without an omental patch. Three patients (17.6%) who were begun by the laparoscopic approach had to be converted to open surgery. Eighteen patients underwent conventional open surgery. The mean operative time for laparoscopic repair was 42.10 minutes (range, 35-60), which was significantly shorter than the 55.83 minutes for open repair (range, 35-72; P = 0.001). Postoperative parenteral analgesic requirements were lower after laparoscopic repair (75.0 mg) than that after an open repair procedure (101.39 mg; P = 0.02). There was no statistically significant difference between the procedures in terms of hospital stay (5 vs. 5.33 days; P = 0.37) and the timing of access to normal daily activity (6.8 vs. 7.1 days) (P = 0.54).

CONCLUSIONS

Laparoscopic surgery, when optimized by a simple repair without an omental patch and 10 mm of a large-channel aspirator-irrigator, may be safely and effectively applied to the patients with small duodenal perforated peptic ulcers (<10 mm) and because of its having low risk factors. The procedure may be an alternative treatment to other procedures when in experienced hands.

The laparoscopic approach in abdominal emergencies: has the attitude changed? : A single-center review of a 15-year experience

BACKGROUND

Laparoscopy has been practiced more and more in the management of abdominal emergencies. The aim of the present work was to illustrate retrospectively the results of a case-control 5-year experience of laparoscopic versus open surgery for abdominal emergencies carried out at our institution, especially with regard to whether our attitude toward use of this procedure has changed as compared with the beginning of our laparoscopic emergency experience (1991-2002).

MATERIALS AND METHODS

From January 2002 to January 2007 a total of 670 patients underwent emergent and/or urgent laparoscopy (small bowel obstruction, 17; gastroduodenal ulcer disease, 16; biliary disease, 118; pelvic disease and non-specific abdominal pain (NSAP), 512; colonic perforations, 7) at the hands of a surgical team trained in laparoscopy

RESULTS

The conversion rate was 0.15%. Major complications ranged as high as 1.9% with no postoperative mortality. A definitive diagnosis was accomplished in 98.3% of the cases, and all such patients were treated successfully by laparoscopy.

CONCLUSIONS

We believe that laparoscopy is not an alternative to physical examination/good clinical judgment or to conventional noninvasive diagnostic methods in treating the patient with symptoms of an acute abdomen. However it must be considered an effective option in treating patients in whom these methods fail and as a challenging alternative to open surgery in the management algorithm for abdominal emergencies.

Laparoscopic two-stage left colonic resection for patients with peritonitis caused by acute diverticulitis

PURPOSE

Purulent or fecal peritonitis is one of the most serious complications of acute diverticulitis. Up to one-fourth of patients hospitalized for acute diverticulitis require an emergent operation for a complication, including abscess, peritonitis, or stenosis. Open Hartmann's procedure has been the operation of choice for these patients. The advantages of laparoscopy could be combined with those of the primary resection in selected patients with peritonitis complicating acute diverticulitis. However, because of technical difficulties and the theoretic risk of poorly controlled sepsis, laparoscopic Hartmann's procedure has been seldom reported for such patients.

METHODS

Data were prospectively collected from 2003 to 2005 in a single referral center specialized in abdominal emergencies. Laparoscopic Hartmann's procedure (Stage 1) was performed in selected patients with peritonitis complicating acute diverticulitis. Secondarily, Hartmann's reversal (Stage 2) also was performed laparoscopically.

RESULTS

Thirty-one patients were studied. The median Mannheim Peritonitis Index score was 21 (+/-5; range, 12-32). The conversion rate was 19 and 11 percent for Stage 1 and Stage 2, respectively. There was no perioperative uncontrolled sepsis. Overall operative 30-day mortality and morbidity rates were 3 and 23 percent for Stage 1, and 0 and 15 percent for Stage 2, respectively. Stoma reversal was possible in 90 percent of patients.

CONCLUSIONS

The results of this small series demonstrated that the indications of laparoscopy in diverticulitis could be extrapolated to selected patients with peritonitis. The technical feasibility and safety of laparoscopic Hartmann's procedure in selected patients seem acceptable. However, larger-scale, controlled studies are needed to define more accurately the role of laparoscopy in complicated diverticulitis.

Perforated peptic ulcer in children: a 20-year experience

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.

Direct visualization of perforation sites in patients with a non-traumatic free pneumoperitoneum: added diagnostic value of thin transverse slices and coronal and sagittal reformations for multi-detector CT

The incremental diagnostic value of adding 1.25-mm slices and coronal and sagittal reformatting to 5-mm axial reconstructions for direct visualization of the perforation site in patients with non-traumatic free pneumoperitoneum was assessed. Forty patients with non-traumatic bowel perforation and free pneumoperitoneum underwent computed tomography (CT). The perforation was gastroduodenal in 18 patients and involved the small or large bowel in 22 patients. Transverse scans were reconstructed with 5-mm thick sections at 5-mm intervals and 1.25-mm-thick sections at 1.25-mm intervals. The second data set was reformatted coronally and sagittaly with 3-mm-thick sections at 3-mm intervals. Three independent blinded readers interpreted 5-mm transverse scans, then combined 1.25-mm and 5-mm-transverse scans, and then combined transverse, coronal and sagittal scans. The rate of identification of the perforation site ranged from 43% to 53% with the combined axial, sagittal and coronal scans, from 28% to 48% with the 1.25- and 5-mm transverse scans, and from 5% to 20% only with the 5-mm thick transverse scans. The agreement between readers was significantly higher with thin slices and reformatting. The use of 1.25-mm axial slices and reformations intrinsically contained more useful diagnostic information than 5-mm axial slices alone for diagnosis of the perforation site in patients with pneumoperitoneum.

Tratamiento laparoscópico de la úlcera duodenal perforada

OBJECTIVE

To analyze the results obtained in patients undergoing laparoscopic surgery for perforated duodenal ulcer.

PATIENTS AND METHOD

From January 2000 to August 2006, 15 consecutive patients with perforated duodenal ulcer underwent laparoscopic surgery after preoperative selection (ASA scores, time since onset of the perforation).

RESULTS

The mean age was 44.6 +/- 15.5 years (range, 18-75). There were 10 men and five women. Fourteen patients were ASA I-II. Time since onset of perforation was more than 12 hours in only one patient. Operative time was 70.5 +/- 9.6 minutes. There were two conversions (13.3%) to the open approach and two postoperative complications (prolonged ileus in one patient and self-limiting leakage in another). There were no intra-abdominal collections or mortality in the entire series. The mean length of hospital stay was 6.5 +/- 2.1 days.

CONCLUSIONS

In selected patients, laparoscopic treatment of perforated duodenal ulcer is safe and feasible. Technical standardization and appropriate patient selection are essential to define the real role of the laparoscopic approach in perforated duodenal ulcer.

Complications of peptic ulcer disease in children and adolescents: minimally invasive treatments offer feasible surgical options

PURPOSE

Surgery for complications of peptic ulcer disease (PUD) carries a significant morbidity and even mortality. The aim of this study was to determine the efficacy, safety, and outcome of children and adolescents undergoing minimally invasive treatment of bleeding and perforation complicating PUD.

METHODS

One hundred thirty-two consecutive patients aged 6 to 17 years managed endoscopically for bleeding and laparoscopically for perforation from January 1999 to February 2006 were reviewed.

RESULTS

Thirty children had significant endoscopic stigma of recent hemorrhage. Primary endoscopic hemostasis was achieved in most cases except one requiring further endoscopic hemostasis. Seventeen patients with perforation underwent laparoscopic patch repair. Four patients were converted to open repair because of technical difficulty and the large size of the ulcer. All patients had a course of proton pump inhibitors postoperatively. Ninety percent of patients had Helicobacter pylori infestation. Triple therapy was given. Two patients defaulted triple therapy and presented later with recurrent ulcer bleeding. All others remained asymptomatic on follow-up (average, 32.6 months).

CONCLUSIONS

Endoscopic hemostasis of bleeding peptic ulcer is effective and safe in children. With stringent criteria, laparoscopic patch repair of perforation can be applied safely to most pediatric patients. Eradication of H pylori and subsequent antiulcer medication are integral in the management of complicated PUD.

Emergency laparoscopy--current best practice

Emergency laparoscopic surgery allows both the evaluation of acute abdominal pain and the treatment of many common acute abdominal disorders. This review critically evaluates the current evidence base for the use of laparoscopy, both diagnostic and interventional, in the emergency abdomen, and provides guidance for surgeons as to current best practise. Laparoscopic surgery is firmly established as the best intervention in acute appendicitis, acute cholecystitis and most gynaecological emergencies but requires further randomised controlled trials to definitively establish its role in other conditions.
