An unusual presentation of perforated appendicitis in epigastric region

INTRODUCTION

Atypical presentations of appendix have been reported including backache, left lower quadrant pain and groin pain from a strangulated femoral hernia containing the appendix. We report a case presenting an epigastric pain that was diagnosed after computed tomography as a perforated appendicitis on intestinal malrotation.

PRESENTATION OF CASE

A 27-year-old man was admitted with a three-day history of epigastric pain. Physical examination revealed tenderness and defense on palpation of epigastric region. There was a left subcostal incision with the history of diaphragmatic hernia repair when the patient was 3 days old. He had an intestinal malrotation with the cecum fixed at the epigastric region and the inflamed appendix extending beside the left lobe of liver.

DISCUSSION

While appendicitis is the most common abdominal disease requiring surgical intervention seen in the emergency room setting, intestinal malrotation is relatively uncommon. When patients with asymptomatic undiagnosed gastrointestinal malrotation clinically present with abdominal pain, accurate diagnosis and definitive therapy may be delayed, possibly increasing the risk of morbidity and mortality.

CONCLUSION

Atypical presentations of acute appendicitis should be kept in mind in patients with abdominal pain in emergency room especially in patients with previous childhood operation for diaphragmatic hernia.     

The diagnostic value of white cell count,C-reactive protein and bilirubin in acute appendicitis and its complications

Introduction

Inflammatory markers such as white cell count (WCC) and C-reactive protein (CRP) and, more recently, bilirubin have been used as adjuncts in the diagnosis of appendicitis. The aim of this study was to determine the diagnostic accuracy of the above markers in acute and perforated appendicitis as well as their value in excluding the condition.

Methods

A retrospective analysis of 1,169 appendicectomies was performed. Patients were grouped according to histological examination of appendicectomy specimens (normal appendix = NA, acute appendicitis = AA, perforated appendicitis = PA) and preoperative laboratory test results were correlated. Receiver operating characteristic (ROC) curve area analysis (area under the curve [AUC]) was performed to examine diagnostic accuracy.

Results

ROC analysis of all laboratory variables showed that no independent variable was diagnostic for AA. Good diagnostic accuracy was seen for AA when all variables were combined (WCC/CRP/bilirubin combined AUC: 0.8173). In PA, the median CRP level was significantly higher than that of AA (158mg/l vs 30mg, p<0.0001). CRP also showed the highest sensitivity (100%) and negative predictive value (100%) for PA. CRP had the highest diagnostic accuracy in PA (AUC: 0.9322) and this was increased when it was combined with WCC (AUC: 0.9388). Bilirubin added no diagnostic value in PA. Normal levels of WCC, CRP and bilirubin could not rule out appendicitis.

Conclusions

CRP provides the highest diagnostic accuracy for PA. Bilirubin did not provide any discriminatory value for AA and its complications. Normal inflammatory markers cannot exclude appendicitis, which remains a clinical diagnosis.     

Systematic review of blunt abdominal trauma as a cause of acute appendicitis

INTRODUCTION

Acute appendicitis commonly presents as an acute abdomen. Cases of acute appendicitis caused by blunt abdominal trauma are rare. We present a systematic review of appendicitis following blunt abdominal trauma. The aim of this review was to collate and report the clinical presentations and experience of such cases.

SUBJECTS AND METHODS

A literature review was performed using PubMed, Embase and Medline and the keywords ‘appendicitis’, ‘abdominal’ and ‘trauma’.

RESULTS

The initial search returned 381 papers, of which 17 articles were included. We found 28 cases of acute appendicitis secondary to blunt abdominal trauma reported in the literature between 1991 and 2009. Mechanisms of injury included road-traffic accidents, falls, assaults and accidents. Presenting symptoms invariably included abdominal pain, but also nausea, vomiting and anorexia. Only 12 patients had computed tomography scans and 10 patients had ultrasonography. All reported treatment was surgical and positive for appendicitis.

CONCLUSIONS

Although rare, the diagnosis of acute appendicitis must be considered following direct abdominal trauma especially if the patient complains of abdominal right lower quadrant pain, nausea and anorexia. Haemodynamically stable patients who present shortly after blunt abdominal trauma with right lower quadrant pain and tenderness should undergo urgent imaging with a plan to proceed to appendicectomy if the imaging suggested an inflammatory process within the right iliac fossa.     

Factors predicting significant pathology on ultrasonography in women presenting with non-specific lower abdominal pain

INTRODUCTION

Ultrasonography is used frequently to exclude significant pathology in young women presenting with nonspecific lower abdominal pain (NSLAP). This study examined parameters that predicted the likelihood of significant findings on ultrasonography. These results could be used to select patients for priority imaging or identify those who could be managed with no ultrasonography.

METHODS

A total of 65 women with NSLAP were identified from 283 admissions. Group 1 (n=42) consisted of patients with normal imaging. Group 2 (n=23) included patients with ‘positive’ scans requiring treatment. White cell count (WCC), C-reactive protein (CRP) levels, platelet count, age, duration of pain and length of stay in hospital were compared between the groups.

RESULTS

The median WCC and CRP were greater in Group 2 than in Group 1: 15 x 10⁹/l and 123mg/l versus 11 x 1071 and 72mg/l respectively (p=0.01 and p=0.05). CRP was a weak predictor of positive pathology on ultrasonography (area under curve [AUC]=0.66, p=0.027) and WCC was a strong predictor of abnormal pathology on ultrasonography (AUC=0.7, p=0.005). A WCC of >12.8 x 10⁹/l was 65% sensitive and 71% specific in predicting subsequent pathology on ultrasonography. The median wait for ultrasonography was 24 hours (range: 1-96 hours).

CONCLUSIONS

This study failed to define any criteria that could select patients not requiring ultrasonography. Since ultrasonography is a relatively cheap and safe investigation, its continued use to screen women with NSLAP is justified. WCC should be used to prioritise imaging.     

Urachal Adenocarcinoma: Incidental Finding at the Time of Surgery for Ruptured Appendicitis

Background:

The urachus is a vestigial structure between the dome of the bladder and the umbilicus. Tumors may develop from the remnants, most of which are well-differentiated, mucinous adenocarcinomas. Urachal adenocarcinoma is an exceedingly rare type of tumor.

Methods:

We present a case of a 51-year-old female presenting to our institution with complaints of abdominal pain for 36 hours. The patient was taken to the operating room for an acute appendicitis. Laparoscopy was performed, and gross purulence and appendiceal perforation were noted as well as a mass on the anterior abdominal wall. Based on the location of the mass, we converted to an open midline laparotomy to treat both the perforated appendicitis and to remove the mass.

Results:

Pathology confirmed the diagnosis of perforated appendicitis and a mucinous-producing urachal adeno-carcinoma.

Discussion:

Data support both open and laparoscopic approaches for appendicitis. This case, although rare, highlights the importance of laparoscopy in a complete and thorough examination of the abdominal cavity. A standard right lower quadrant incision for an open technique would likely have resulted in omission of this lesion, and the patient would have presented at a more typical late stage of her cancer development with significantly more morbidity.     

Pediatric ovarian torsion: case series and review of the literature

Background

Ovarian torsion in children is an uncommon cause of acute abdominal pain but mandates early surgical management to prevent further adnexal damage. The clinical presentation mimics other pathologies, such as appendicitis. We sought to more completely characterize ovarian torsion with respect to pain and ancillary studies, such as urinalysis.

Methods

We performed a retrospective review of hospital charts of all patients aged 0–18 years with a diagnosis of ovarian torsion at the Children’s Hospital at London Health Sciences Centre, in London, Ont., from 1993 to 2008.

Results

We analyzed 13 charts of patients aged 7 months to 18 years. Most patients presented with peripheral leukocytosis, vomiting and right lower quadrant pain that did not radiate or migrate. On urinalysis, about half the patients demonstrated pyuria without bacteruria. Pelvic ultrasound revealed an ovarian cyst on the same side of the pain in 11 of 13 patients. Most were found to have a hemorrhagic cyst or ovary and underwent salpingo-oophorectomy or cystectomy within 48 hours of presentation.

Conclusion

Ovarian torsion should be considered in any female child with acute onset lower abdominal pain accompanied by vomiting. Pain can be characterized as constant or colicky, but unlike with appendicitis, does not typically migrate. Sterile pyuria is found in a substantial proportion of cases. Ultrasound is the most useful initial diagnostic modality, but the absence of flow on Doppler imaging is not always present. Conservative management with detorsion and oophoropexy is recommended.     

A Clinicopathological Review of 324 Appendices Removed for Acute Appendicitis in Durban,South Africa: A Retrospective Analysis

INTRODUCTION

Acute appendicitis remains a common surgical condition and the importance of specific elements in the clinical diagnosis remain controversial. A variety of neoplastic and inflammatory conditions mimic acute appendicitis. The purpose of this study was to determine the presenting pattern of acute appendicitis and to review the pathological diagnosis.

PATIENTS AND METHODS

This is a retrospective analysis of 324 patients who had appendicectomy for acute appendicitis at Prince Mshiyeni Memorial Hospital (Natal, South Africa) during the period January 2002 to December 2004. Patient demographics, clinical features, white cell count, operative findings, outcome and histology results were recorded on a special patient proforma.

RESULTS

A total of 371 patients underwent appendicectomy during this period and 324 (M:F, 3.6:1) were available for analysis. The majority of our patients were in the second decade (43.1%) with only 29.3% presenting within 24 h of onset of symptoms. The most common symptoms were abdominal pain (100%), vomiting (57.4%) and anorexia (49.0%). Generalised and localised abdominal tenderness were present in 62.0% and 19.4% of patients, respectively. Pyrexia was noted in 41.0%. Localised and generalised peritonitis were present in 26.4% and 14.0%, respectively. The most common incisions were lower midline laparotomy (47.2%) and gridiron (37.3%). The negative appendicectomy rate was 17.0%. Acute appendiceal inflammation and gangrenous appendicitis was present in 36.1% and 9.6%, respectively. The perforation rate was 34.0% and there was a direct correlation with delayed presentation. There were no patients with carcinoid tumour or adenocarcinoma. Parasites and other associated conditions were seen in 8.6% of cases. Postoperative complications included: wound sepsis (25.3%), prolonged ileus (6.2%), peritonitis (4.6%) and chest infection (3.4%). Four patients died (1.2%) all from the perforated group.

CONCLUSIONS

Our patients present late with advanced disease and complications. All surgeons should bear in mind the possibility of parasitic infestations mimicking acute appendicitis and the presence of significant unusual histological findings in our setting justifies routine histopathological examination of appendices.     

SINGLE-INCISION VIDEOLAPAROSCOPIC APPENDECTOMY WITH CONVENTIONAL VIDEOLAPAROSCOPY EQUIPMENT

Background

Acute appendicitis is the most common surgical emergency in daily practice, and is approached laparoscopically in many centers. Efforts have been undertaken for the development of minimally invasive techniques that reduce tissue trauma and offer improved cosmetic results, one of such being the single-incision laparoscopic surgery (SILS).

Aim

To present a minimally invasive technique for appendectomy (SILS) undertaken with conventional instruments.

Method

Eleven patients were treated in the emergency care center presenting abdominal pain in the right iliac fossa that was suggestive of appendicitis. Diagnostic investigation was subsequently conducted, including physical examination, laboratory and imaging exams (CT scan with intravenous contrast or total abdominal ultrasound), and the results were consistent with acute appendicitis. Thus, after consent, these patients underwent SILS appendectomy under general anesthesia with three trocars (two 10 mm and one 5 mm), using conventional and optical laparoscopic tweezers (10 mm, 30º). The base and pedicle of the appendix were ligated with titanium LT 400 clips. The procedure occurred uneventfully. Inclusion criteria were absence of diffuse peritonitis, BMI (body mass index) less than 35 and absence of serious comorbidities or sepsis.

Results

Seven men and four women were operated with average age of 25.7 years and underwent appendectomy through this technique. Mean procedure duration was of 37.2 min. Regarding surgical findings, three had appendicitis in stage 1, four in stage 2 and four in stage 3. All patients improved well, without surgical complications, and did not require conversion to open surgery or conventional laparoscopy technique.

Conclusion

Appendectomy conducted through Single Incision Laparoscopic Surgery is a feasible and promising technique that can be performed with conventional laparoscopic instruments.     

Diagnostic markers in acute appendicitis

Background

An adequate medical history combined with clinical examination is usually enough to make the diagnosis of acute appendicitis. The aim of this study was to determine the value of elevated white cell count (WCC), C-reactive protein (CRP), and bilirubin as diagnostic markers of acute appendicitis.

Methods

A retrospective analysis was carried out on consecutive patients who underwent appendicectomy over a 3-year period. All data including patients' age, sex, blood test results, and appendix histology were summarized. Sensitivities, specificities, positive, and negative predictive values of WCC, CRP, and bilirubin were calculated separately or in combination for all patients.

Results

A total of 447 patients were included. There is a significant difference in the results between patients with negative and positive appendicitis with regards to CRP (32 vs 73; P < .001), mean total WCC (10.9 vs 14.0; P < .001), and the mean levels of bilirubin (10.9 vs 17.2; P < .001).

Conclusions

The diagnosis of appendicitis remains multifactorial and blood tests may help to guide the surgeon in the decision making.     

Laparoscopic appendectomy for torsed appendix presenting as an acute abdomen in an infant female

Background:

Torsion of an otherwise normal appendix vermiformis is exceedingly rare and usually presents with symptoms consistent with acute appendicitis. We present the unusual case of an infant girl who was admitted with right lower quadrant pain and focal peritonitis who was found to have appendiceal torsion on laparoscopy.

Case Report:

An 11-week-old girl was brought to the emergency department with a 48-hour history of abdominal pain, emesis, low-grade fever, and focal right lower quadrant tenderness. Sonography found a noncompressible distended appendix in the right lower quadrant. Upon laparoscopy, a torsed, necrotic appendix vermiformis was found. Appendectomy was performed, and the patient recovered uneventfully.

Conclusion:

In an infant girl with lower abdominal pain, the differential diagnosis should include torsed appendix besides more common causes, such as torsed ovary, intussusception, or small bowel volvulus. Ultrasound is useful for planning the operative approach.     

Amebiasis presenting as acute appendicitis: Report of a case and review of Japanese literature

INTRODUCTION

Outside of these high-risk regions, acute amebic appendicitis is considerably rarer and the mortality rate is much higher than with non-amebic appendicitis.

PRESENTATION OF CASE

A 31-year-old woman presented with fever and right lower abdominal pain with no history of traveling abroad or sexual infection. Computed tomography revealed a dilated appendix and thickened cecal and ascending colon walls. She underwent an appendectomy for appendicitis. Owing to a lack of symptom resolution, we performed a pathologic examination of the appendix again that revealed multiple Entamoeba histolytica trophozoites; the serum amebic antibody was positive. She was treated postoperatively with metronidazole for amebiasis and discharged on postoperative day 12.

DISCUSSION

The mortality rate and frequency of severe postoperative intraabdominal complications were higher in the Japanese literature (1995–2013) (25% and 33%, respectively) than in other developed countries (3.3% and 19.4%, respectively). Japan is a low-risk area for amebiasis; many physicians fail to consider amebiasis in the differential diagnosis of acute abdomen. It is important to conduct further examinations, including those for amebiasis, when appendectomy does not resolve acute appendicitis.

CONCLUSION

We report a case of acute amebic appendicitis in a 31-year-old woman and review the ages at presentation, causative factors, treatments, and outcomes of 11 cases reported in Japan between 1995 and 2013.     

Ultrasonography aids decision-making in children with abdominal pain

INTRODUCTION

Although regular clinical assessment of the acute abdomen is considered best practice, ultrasonography confirming the presence of appendicitis will add to the decision-making process. The aim of this study was to assess the accuracy of ultrasonography and its usefulness in diagnosing acute appendicitis in a regional paediatric surgical institution.

METHODS

Retrospectively and in this order, radiology, theatre and histopathology databases were searched for patients who had presented with acute abdominal pain, patients who had undergone an appendicectomy and all appendix specimens over a two-year period. The databases were cross-referenced against each other.

RESULTS

A total of 273 non-incidental appendicectomies were performed over the study period. The negative appendicectomy rate was 16.5% and the perforation rate 23.7%. Thirty-nine per cent of children undergoing an appendicectomy had at least one pre-operative ultrasound scan. Ultrasonography as a diagnostic tool for acute appendicitis in children had a sensitivity of 83.3%, a specificity of 97.4 %, a positive predictive value of 92.1% and a negative predictive value of 94.0%.

CONCLUSIONS

Ultrasonography is used liberally to aid in the decision making process of equivocal and complicated cases of acute appendicitis and it achieves good measures of accuracy. As a diagnostic tool it is unique in its ability to positively predict as well as exclude. A high negative predictive value suggests that more patients could be managed on an outpatient basis following a negative scan.     

Impact of computed tomography of the abdomen on clinical outcomes in patients with acute right lower quadrant pain: a meta-analysis

Background

Clinical evaluation alone is still considered adequate by many clinicians who treat patients with appendicitis. The impact of computed tomography (CT) on clinical outcomes remains unclear, and there is no consensus regarding the appropriate use of CT in these patients. We sought to evaluate the impact of abdominal CT on the clinical outcomes of patients presenting with suspected appendicitis.

Methods

We conducted a systematic review of the literature to identify studies that examined clinical outcomes related to the use of abdominal CT in the diagnosis of acute appendicitis. Inclusion criteria were studies of adult patients with suspected appendicitis that evaluated the impact of abdominal CT on negative appendectomy rates, perforation rates or time to surgery. Two independent investigators reviewed all titles and abstracts and extracted data from 28 full-text articles. Statistical analysis was conducted using Review Manager 5.0.10 software.

Results

The negative appendectomy rate was 8.7% when using CT compared with 16.7% when using clinical evaluation alone (p < 0.001). There was also a significantly lower negative appendectomy rate during the CT era compared with the pre-CT era (10.0% v. 21.5%, p < 0.001). Time to surgery was evaluated in 10 of the 28 studies, 5 of which demonstrated a significant increase in the time to surgery with the use of CT. Appendiceal perforation rates were unchanged by the use of CT (23.4% in the CT group v. 16.7% in the clinical evaluation group, p = 0.15). Similarly, the perforation rate during the CT era was not significantly different than that during the pre-CT era (20.0% v. 19.6%, p = 0.74).

Conclusion

This meta-analysis supports the hypothesis that the use of preoperative abdominal CT is associated with lower negative appendectomy rates. The use of CT in the absence of an expedited imaging protocol may delay surgery, but this delay is not associated with increased appendiceal perforation rates. Routine CT in all patients presenting with suspected appendicitis could reduce the rate of unnecessary surgery without increasing morbidity.     

Appendiceal diverticulum associated with chronic appendicitis

INTRODUCTION

Appendiceal diverticulosis is a rare entity, with a global incidence between 0.004% and 2.1% of all appendectomies. It has been related with an elevated risk of perforation in comparison to acute appendicitis, as well as an increased risk for synchronic appendicular cancer in 48% of the cases, and colonic cancer in 43%. The incidence of chronic appendicitis has been reported in 1.5% of all appendicitis cases.

PRESENTATION OF CASE

We present a 73-year-old female, with no relevant familial history, who presented due to a four-month-long oppressive, moderate pain in the lower right abdominal quadrant without irradiation or any other accompanying symptoms.

DISCUSSION

The documented incidence of appendiceal diverticula and chronic appendicitis by themselves is low; therefore the presence of both entities at the same time is extremely rare.

CONCLUSION

We present a case in which both diagnoses concurred in the same patient. The relevance of this case relies on the importance of the adequate knowledge of these pathologies, so we can approach them correctly. Although it does not represent an absolute surgical emergency, appendectomy represents the first therapeutic option.     

Diagnostic laparoscopy in a twelve year old girl with right iliac fossa pain: A life changing diagnosis of complete androgen insensitivity syndrome

INTRODUCTION

Right iliac fossa (RIF) pain is one of the most common presenting complaints faced by general surgeons in the emergency department. Correct diagnosis and appropriate surgical intervention can often pose a challenge.

PRESENTATION OF CASE

A 12-year-old girl presented to the emergency department with a four day history of initially central acute abdominal pain, now localised in the RIF. During laparoscopy, the following findings were made: macroscopically dilated appendix, right and left gonads at the internal opening of the inguinal canal, empty pelvis with a rudimentary uterus on the right side. No evidence of fallopian tubes or connection of uterus to the vagina and broad based, non-inflamed Meckel''s diverticulum. An incidental diagnosis of complete androgen insensitivity syndrome was made.

DISCUSSION

Androgen insensitivity syndrome (AIS) is a disorder of hormone resistance characterised by a female phenotype in an individual with an XY karyotype and testes producing age-appropriate normal concentrations of androgens.

CONCLUSION

This case report highlights the advantage of laparoscopy as a diagnostic and treatment tool in a twelve year old girl with multiple intra-abdominal findings. While the ultimate diagnosis responsible for her symptom of RIF pain was acute appendicitis, the additional diagnosis of CAIS and incidental Meckel''s would have otherwise likely gone undetected.     

To CT or not to CT? The influence of computed tomography on the diagnosis of appendicitis in obese pediatric patients

Background

Appendicitis is a common pediatric query. However, obesity often results in nondiagnostic ultrasounds and increased likelihood of abdominal computed tomography (CT). Concern regarding radiation exposure led the Canadian Association of Radiologists to recommend foregoing CT when ultrasounds are nondiagnostic and clinical suspicion is high. We evaluated this recommendation by quantifying the influence of CT on the diagnosis of pediatric appendicitis.

Methods

We performed a 2-year retrospective case series of children presenting with suspected appendicitis. We stratified patients by weight (obese v. nonobese) and pediatric appendicitis score (PAS) and examined how often they received abdominal CT, why they received it, and its influence on diagnosis.

Results

Of 223 patients (84 obese, 139 nonobese), 54 received CT. Obese patients received CTs more frequently than nonobese patients (29% v. 22%). The most common reason for CT was a nondiagnostic ultrasound (75% in obese, 80% in nonobese patients). Sixty-five percent of CTs obtained after nondiagnostic ultrasounds confirmed the initial diagnosis, but the rates were 80% and 50%, respectively, when only obese and only nonobese patients were considered. Obese patients were 4 times more likely to have a CT confirming their initial appendicitis diagnosis.

Conclusion

Because obese patients are more likely than nonobese patients to have a CT that confirms appendicitis, when treating an obese pediatric patient with suspected appendicitis and a nondiagnostic ultrasound, surgeons with a high clinical suspicion should strongly consider foregoing CT and proceeding with treatment.     

A rare complication of acute appendicitis: Superior mesenteric vein thrombosis

Introduction

Very few cases of superior mesenteric vein thrombosis have been reported as a complication of appendicitis. In these handful of cases, the thrombosis was identified early with computerised tomography scan and patients have been managed conservatively with antibiotics and anticoagulation.

Presentation of case

A 45-year-old gentleman presented to the emergency department with a 13-day history of right lower quadrant abdominal pain and rigors. CT scan of the abdomen revealed an appendicular mass and superior mesenteric vein thrombosis. The patient was initially managed by anticoagulation and antibiotics for two weeks and was discharged after satisfactory clinical improvement. He represented after discharge for increased severity of his abdominal pain and abnormal inflammatory markers. Emergency open appendicectomy for complicated appendicitis was performed and his postoperative course was unremarkable. He was discharged on the 7th postoperative day with anticoagulation. Outpatient review at two months was unremarkable.

Discussion

Acute appendicitis is a common surgical presentation where history and examination is key in clinching the diagnosis. Inflammatory markers and imaging modalities such as a CT scan can be helpful. Although surgical intervention is the mainstay of treatment, conservative management with antibiotics is an option if the diagnosis of appendicitis is equivocal. Recent evidence has revealed that elective appendicectomy is not necessary upon successful conservative management. Acute appendicitis can lead to local perforations and abscesses. Complications such as thrombosis in the superior mesenteric vein are rare and can be managed successfully with anticoagulants.

Conclusion

Although this is a rare complication of appendicitis, the case was managed successfully with a conservative approach. This is inline with the general consensus which is to treat superior mesenteric vein thrombosis secondary to appendicitis conservatively unless the patient deteriorates.     

Schistosomiasis as a rare cause of recurrent acute appendicitis – A case report

INTRODUCTION

We are presenting a case of schistosomiasis in a 41 year old lady who presented with right iliac fossa pain for 3 years. The pain worsened and the frequency increased in the last 3 months prior to referral. The ultrasound was unremarkable. Her bowel habits were normal and there was no vomiting. There was no blood in the stool or in the urine.

PRESENTATION OF CASE

The abdomen was soft except on deep palpation. There was slight tenderness in the right lower quadrant. A repeat ultrasound was unremarkable. The full blood count was within the normal range. A diagnosis of recurrent acute appendicitis was made and an interval appendicectomy was performed.

DISCUSSION

Histopathology results revealed schistosomiasis of the appendix. There was no acute inflammation but there was fibrous obliteration of the distal lumen of the appendix and reactive lymphoid hyperplasia.

CONCLUSION

This is the first case in a country with relatively clean drinking water. There are no irrigation schemes but there are seasonal rivers and streams. The patient admits to swimming in these streams during childhood. Clinical features of schistosomiasis were not elicited.     

Postpartum ovarian vein thrombosis

Background:

Ovarian vein thrombosis (OVT) is a rare but potentially serious postpartum complication, which occurs in 0.05% to 0.18% of pregnancies and is diagnosed on the right side in 80% to 90% of the cases.

Case Report:

A 32-year-old woman presented at 15 days postpartum to our emergency department with severe abdominal pain, fever, and abdominal distension. Abdominal examination revealed right lower quadrant pain with rebound tenderness. The plain abdominal radiography evidenced a diffuse fecal stasis; abdominal ultrasound showed the presence of free fluid in the Douglas’ pouch and between small bowel loops. Diagnosis of acute appendicitis was made. The patient immediately underwent explorative laparoscopy; at surgery, a woody tumoration consistent with right ovarian vein thrombosis was found. Laparoscopic ultrasound confirmed the diagnosis. Anticoagulation therapy and antibiotics were instituted. CT-scan confirmed the presence of thrombosis up to the vena cava. The patient was discharged on postoperative day 4. At 1-month follow-up, she remained stable and symptom free.

Discussion:

Even though postpartum ovarian vein thrombosis is rare, recognition and treatment is needed to institute adequate therapy and avoid potential serious sequelae. The diagnosis can be established by ultrasound, CT scan, and MRI examinations, although, as in the case described, the limitation of ultrasound includes obscuration of the gonadic vein by overlying bowel gas.

Conclusion:

OVT should be considered in any woman in the postpartum period with lower abdominal pain, fever, and leucocytosis.     

A Comparison of Laparoscopic and Open Appendectomy

Background and Objectives:

To compare laparoscopic appendectomy with traditional open appendectomy.

Methods:

Seventy-one patients requiring operative intervention for suspected acute appendicitis were prospectively compared. Thirty-seven patients underwent laparoscopic appendectomy, and 34 had open appendectomy through a right lower quadrant incision. Length of surgery, postoperative morbidity and length of postoperative stay (LOS) were recorded. Both groups were similar with regard to age, gender, height, weight, fever, leukocytosis, and incidence of normal vs. gangrenous or perforated appendix.

Results:

Mean LOS was significantly shorter for patients with acute suppurative appendicitis who underwent laparoscopic appendectomy (2.5 days vs. 4.0 days, p<0.01). Mean LOS was no different when patients classified as having gangrenous or perforated appendicitis were included in the analysis (3.7 days vs. 4.1 days, P=0.11). The laparoscopy group had significantly longer surgery times (72 min vs. 58 min, p<0.001). There was no significant difference in the incidence of postoperative morbidity.

Conclusions:

Laparoscopic appendectomy reduces LOS as compared with the traditional open technique in patients with acute suppurative appendicitis. The longer operative time for the laparoscopic approach in our study is likely related to the learning curve associated with the procedure and did not increase morbidity.
