Acute appendicitis with unusual dual pathology

INTRODUCTION

Meckel''s diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1–3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult.

PRESENTATION OF CASE

We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel''s diverticulum causing intussusception.

DISCUSSION

Intestinal obstruction in patients with Meckel''s diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture.

CONCLUSION

Consideration of Meckel''s diverticulum although a rare diagnosis is imperative and this case raises the question “should surgeons routinely examine the bowel for Meckel''s diverticulum at laparoscopy?”     

A large incarcerated Meckel's diverticulum in an inguinal hernia

INTRODUCTION

Littre''s hernia is a rare finding consisting of a Meckel''s diverticulum inside of a hernia sac. Clinically, it is indistinguishable from a hernia involving small bowel and therefore may be difficult to diagnose pre-operatively.

PRESENTATION OF CASE

We report a case of an inguinal hernia involving an unusually large Meckel''s diverticulum measuring 15 cm in length. The diverticulum was resected using a linear GI stapler and the hernia was repaired without complication.

DISCUSSION

Meckel''s diverticulum is an embryologic remnant of the vitelline duct occurring in 1–3% of the adult population with an estimated 4% becoming complicated and presenting with intestinal obstruction, infection, bleeding or herniation. Surgical resection is the recommended treatment for any Meckel''s diverticulum causing symptoms. In the case of a Littre''s hernia, resection of the diverticulum should be followed by repair of the fascial defect in a standard fashion.

CONCLUSION

Littre''s hernia, although rare, should be a consideration at the time of repair for any abdominal hernia involving small bowel as resection of the Meckel''s diverticulum is critical in avoiding recurrent complications.     

Unusual association of Meckel's diverticulum with double appendix – A rare finding

INTRODUCTION

Appendix duplication is an extremely rare congenital anomaly that is seen in 0.004–0.009% of appendectomy specimens. Duplicated appendix may be associated with number of congenital anomalies.

PRESENTATION OF CASE

In this case report, we are presenting a rare case of duplicated vermiform appendix with a co-existing Meckel''s diverticulum.

DISCUSSION

Anomalies of appendix are rare and duplication of vermiform appendix is extremely rare. In 1936, Cave classified appendiceal duplication for the first time which was modified by Wallbridge in 1963 into three types. Concomitant malformations or duplications of the large intestine or the genitourinary system may be present, especially in types B1 and C probably due to their similar embryological origin. Here we are presenting a very rare case report of type B1 appendix anomaly associated with Meckel''s diverticulum.

CONCLUSION

Surgeons should be aware of these conditions because of the possible clinical implications.     

Laparoscopic treatment of bowel obstruction due to a bezoar in a Meckel's diverticulum

Background and Objectives:

Meckel''s diverticulum is a common anomaly of the gastrointestinal tract that may result in gastrointestinal bleeding, diverticulitis, and small bowel obstruction. This report describes the use of laparoscopy to treat a rare complication of Meckel''s diverticulum–small bowel obstruction due to phytobezoar impaction. More generally, it provides an example of the feasibility and utility of a laparoscopic approach to small bowel obstructions of unknown causes.

Methods:

A 34-year-old male presented to the emergency department complaining of episodic abdominal pain and vomiting. He had no history of abdominal surgery. His vital signs were stable, and his abdomen was distended, but only mildly tender. He had no abdominal wall hernias on examination. Imaging was consistent with small bowel obstruction. He was brought to the operating room where laparoscopy revealed a Meckel''s diverticulum with an impacted phytobezoar as the source of obstruction. The diverticulum was resected and the phytobezoar removed laparoscopically.

Results:

The patient recovered well and was discharged home on the third postoperative day, tolerating a regular diet.

Conclusions:

Phytobezoar impaction in a Meckel''s diverticulum causing small bowel obstruction is a rare event. It can be effectively treated laparoscopically. This case provides an example of the potential utility of laparoscopy in treating small bowel obstructions of unclear etiology.     

A case report: Cecal volvulus caused by Meckel's diverticulum

INTRODUCTION

Meckel''s diverticulum is the most common congenital anomaly of the small intestine. Common complications related to Meckel''s diverticulum include hemorrhage, intestinal obstruction and inflammation. Acute large bowel obstruction is a rare complication of Meckel''s diverticulum and in the presented case it is caused by volvulus.

PRESENTATION OF CASE

We report a 39 year old female who presented with the diagnosis of a large bowel obstruction occurring as a result of cecal volvulus caused by adhesions of a perforated diverticulum.

DISCUSSION

The reported case presents one of the rare complications of MD, which is volvulus. The case described above presented with signs and symptoms suggestive of acute intestinal obstruction and radiological findings suggestive of cecal volvulus. The patient was taken to the operation room for exploration and we discovered the presence of a perforated MD. The main treatment of such case is to perform diverticulectomy in all symptomatic patients.

CONCLUSION

MD is mostly identified intraoperatively. Knowledge of the pathophysiologies by which MD can cause complications such as volvulus is important in order to plan management.     

A combined Richter's and de Garengeot's hernia

INTRODUCTION

de Garengeot''s hernia is very rare. Richter''s hernia is responsible for 10% of acute strangulated hernias.

PRESENTATION OF CASE

A 91-year-old woman with three days of abdominal distention was found on computed tomogram to have an incarcerated femoral hernia. Operation revealed a de Garengeot''s hernia combined with a Richter''s hernia of small bowel. Primary repair was performed along with appendectomy.

DISCUSSION

We discuss these rare hernias, not previously reported in combination, and options for management.

CONCLUSION

Combined de Garengeot''s and Richter''s hernias are rare, represent a significant diagnostic challenge, and should be repaired urgently to prevent ischemic bowel, or limit contamination if ischemia is already present. Use of computed tomography will likely lead to increased pre-operative diagnosis of this rare entity.     

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.     

A De Garengeot Hernia masquerading as a strangulated femoral hernia

INTRODUCTION

De Garengeot hernia is a rare occurrence whereby an appendix is found in a femoral hernia sac. It is rarer still to find an acutely inflamed appendix manifesting itself as a strangulated femoral hernia. This case is important to report as it highlights the diagnostic difficulty this particular condition presents to an emergency surgeon.

PRESENTATION OF CASE

We report the case of an 86 year old female who was found to have a De Garengeot hernia containing a necrotic appendix. A retrograde appendicectomy was performed to prevent peritoneal contamination. The hernia defect was repaired using a standard repair with non-absorbable suture.

DISCUSSION

De Garengeot''s hernia is a rare occurrence, is often unexpected and tends to be diagnosed intra-operatively. Pre-operative diagnosis remains difficult and it will often masquerade as a strangulated femoral hernia. In stable patients, where there is a diagnostic uncertainty CT scanning is a useful adjunct and may allow a laparoscopic approach to be undertaken in the absence of appendicitis.

CONCLUSION

A De Garengeot''s hernia should be considered as a differential diagnosis in patients presenting with clinical signs of a strangulated femoral hernia. It is often an incidental finding during an emergency operation. Although mesh repairs in the presence of appendicitis have been reported, the safest approach remains a primary suture repair.     

De Garengeot Hernia

Background and Objectives:

We report a case of appendicitis presenting in an incarcerated femoral hernia, otherwise known as de Garengeot hernia. This rare hernia usually presents with both diagnostic and therapeutic dilemmas. We wish to underline the usefulness of laparoscopy in both the diagnosis and treatment of de Garengeot hernias.

Methods:

A diagnostic laparoscopy was performed initially. The appendix was seen to disappear into the hernia sac. A laparoscopic appendectomy was then performed prior to open exploration of the groin.

Results:

We were able to obtain a correct diagnosis and perform an appendectomy prior to making a groin incision. Operative findings included an incarcerated, inflamed appendix within a femoral hernia.

Conclusions:

Diagnostic laparoscopy could be a valuable tool in the correct diagnosis and management of unusual presentations of incarcerated groin hernias.     

Vanek's tumour mimicking an acute appendicitis

Introduction

Vanek''s tumour or Inflammatory Fibroid Polyp (IFP) are rare, benign localised lesions originating from the sub-mucosa of the gastrointestinal tract (GI) tract.¹ They have been widely reported as occurring within the stomach, Duodenum, Jejunum and Ileum, more rarely (<1%) in the caecum or appendix.

Presentation of case

We present a case of a 28-year-old lady who presented with a 2-day history of right iliac fossa pain, nausea and low-grade fever. Subsequent, ultrasonography (USS) of the abdomen demonstrated an inflamed tubular structure originating from caecum with fluid in the pelvis mimicking an acute appendicitis. Next to normal appendix an inflammatory polypoid mass was identified and on histological examination confirmed to be an IFP (Vanek''s tumour).

Discussion

Right Iliac Fossa (RIF) pain with suspected appendicitis is one of the most common presentations in any acute surgical unit. In young women of childbearing age, the differential diagnosis can be varied and vast. The surgical management of IFP (Vanek''s tumour) in such cases ranges from limited resection and caecectomy to limited right hemicolectomy.

Conclusion

To date, the exact histiogenesis of these tumours remains unclear and requires a high level of intra-operative suspicion. According to our search such presentation is not reported.     

Laparoscopic Appendectomy in Children

Background and Objectives:

The advantages of laparoscopic appendectomy over open appendectomy have not yet been clearly demonstrated. The present study evaluated our early experience with laparoscopic appendectomy in children, in terms of its safety, effectiveness, technical difficulties, and economics.

Methods:

We reviewed the records of 50 cases involving laparoscopic appendectomy performed at our affiliated institutions between September, 1994, and September, 1996. Patient age ranged from 6 to 18 years (mean, 14 years). Thirty-two patients had acute nonperforated appendicitis, six had perforated appendicitis, two had fibrosis of the appendix, and ten had a histologically normal appendix.

Results:

In five patients the laparoscopic procedures were converted to open appendectomies because of technical difficulties. There were postoperative complications in four patients: one incomplete appendectomy which subsequently required an open appendectomy for completion, one pelvic abscess, one bowel obstruction, and one minor wound infection.

Conclusions:

Laparoscopic appendectomy is a safe and effective procedure. It takes longer operative time than open appendectomy. Length of hospitalization and incidence of postoperative complications are equivalent to those of open appendectomy. Economic benefits are difficult to assess at present. In sum, we believe that with better training, surgical techniques and equipment, laparoscopic appendectomy will eventually become the surgical procedure of choice in appendicitis.     

Swelling of the right thigh for over 30 years—The rare finding of a De Garengeot hernia

INTRODUCTION

Femoral hernias may – in some rare cases – contain the appendix, a phenomenon called de Garengeot hernia. It is usually an incidental finding in hernia repair. We found our case to be of interest because of the long standing femoral swelling before peracute appendicitis led to its removal.

PRESENTATION OF CASE

We present the case of a 71-year-old woman with a swelling of the right medial thigh for over more than 30 years. When the swelling suddenly grew in size and became tender, she was referred to our emergency department. Sonographically as well as clinically a femoral hernia was diagnosed. Intraoperatively, the appendix was found and open appendectomy as well as a hernioplasty was performed.

DISCUSSION

Open appendectomy is an elegant and safe procedure to repair a long standing de Garengeot hernia. Most case reports call for extensive diagnostics such as CT scan etc. We found a sonography of the femoral region to be conclusive.

CONCLUSION

Apart from the inherent risk of sudden incarceration in hernias, De Garengeot hernias can also develop peracute appendicitis years after their formation. This differential diagnosis needs to be taken into consideration in patients presenting with the clinical signs of a femoral hernia.     

Laparoscopy and Complicated Meckel Diverticulum in Children

Background and Objectives:

Meckel diverticulum can present with a variety of complications but is often found incidentally during other surgical procedures. The role of laparoscopy in the management of Meckel diverticulum is established. We reviewed our experience with complicated cases of Meckel diverticulum in children managed with laparoscopy.

Methods:

A 15-year retrospective chart review revealed 14 cases of complicated Meckel diverticulum managed with laparoscopy. Incidentally found Meckel diverticulum and cases done by laparotomy were excluded. Ages varied from 2 years to 16 years old. There were 10 males and four females. Eight cases had small bowel obstruction; of those, three had extensive intestinal gangrene. Four cases had significant rectal bleeding, three had acute diverticulitis, and two had intussusception caused by the diverticulum.

Results:

Eleven cases were treated with laparoscopic Meckel diverticulectomy and three with laparoscopic-assisted bowel resection because of extensive gangrene of the intestine. Two of the three cases with significant intestinal gangrene returned several weeks later with small bowel obstruction secondary to adhesions. They were successfully managed with laparoscopic lysis of adhesions. There were no other complications.

Conclusions:

Laparoscopy is safe and effective in the management of complicated Meckel diverticulum in children. Most cases can be managed with simple diverticulectomy. Laparoscopy is useful when the diagnosis is uncertain. When extensive gangrene is present, laparoscopy can help to mobilize the intestine and evaluate the degree of damage, irrigate and cleanse the peritoneal cavity, and minimize the incision necessary to accomplish the bowel resection.     

Right sided transmesentric hernia: A rare cause of acute abdomen in adults

INTRODUCTION

Transmesenteric mesocolic hernias are a rare cause of acute abdomen in adults with few reported cases in published literature.

PRESENTATION OF CASE

We report a rare case of a 30-year-old male with right-sided transmesenteric hernia of ileum due to a congenital mesocolic defect resulting in acute abdomen, presenting as acute abdomen. The hernia was reduced, small bowel inspected for gangrene and mesenteric hernia repaired, following which the patient made a good recovery and was discharged 5 days later.

DISCUSSION

The insidious onset of transmesenteric herniae and lack of specific radiological or laboratory investigations reaffirms the importance of surgeons maintaining a high index of suspicion for this surgical emergency.

CONCLUSION

Transmesentric hernia though rare can present as a case of acute abdomen in an emergency. The diagnosis is purely by a CT scan and close monitoring of the patient''s general condition in cases of non-specific abdominal pain is essential to identify the rare deteriorating patient for early surgical intervention and optimal outcome.     

A rare case of segmental small bowel pneumatosis intestinalis: A case report

Introduction

Pneumatosis intestinalis is a rare condition affecting 0.03% of the population. It has a myriad of aetiological causes and hence presentation can vary immensely. The management of symptomatic pneumatosis intestinalis in an acute and outpatient setting remains a challenge to both physicians and surgeons.

Case presentation

We present a case of a 79 year old who presented in a gastroenterology outpatients department with a history suggestive of intermittent small bowel obstruction associated with abdominal pain aggravated by eating and posture. He was found to have signs suggestive of Marfan''s syndrome. Computed tomography demonstrated extensive pneumatosis intestinalis of the small bowel. Due to deterioration in symptoms, an exploratory laparotomy was performed demonstrating segmental small bowel pneumatosis intestinalis secondary to a hypermobile mesentery.

Conclusion

This case highlights the importance of both surgical and gastroenterology expertise in successfully managing symptomatic pneumatosis intestinalis.     

Stump appendicitis: a surgeon's dilemma

Background:

Stump appendicitis is defined by the recurrent inflammation of the residual appendix after the appendix has been only partially removed during an appendectomy for appendicitis. Forty-eight cases of stump appendicitis were identified in the English literature.

Database:

The institutional CPT codes were evaluated for multiple hits of the appendectomy code, yielding a total of 3 patients. After appropriate approval from an internal review board, a retrospective chart review was completed and all available data extracted. All 3 patients were diagnosed with stump appendicitis, ranging from 2 months to 20 years after the initial procedure. Two patients underwent a laparoscopic and the one an open completion appendectomy. All patients did well and were discharged home in good condition.

Conclusion:

Surgeons need a heightened awareness of the possibility of stump appendicitis. Correct identification and removal of the appendiceal base without leaving an appendiceal stump minimizes the risk of stump appendicitis. If a CT scan has been obtained, it enables exquisite delineation of the surrounding anatomy, including the length of the appendiceal remnant. Thus, we propose that unless there are other mitigating circumstances, the completion appendectomy in cases of stump appendicitis should also be performed laparoscopically guided by the CT findings.     

Laparoscopic port site Richter's hernia - An important lesson learnt

Introduction

We report a case of small bowel obstruction with strangulation caused by a port site hernia following a laparoscopic appendicectomy and the successful management of the problem by employing a laparoscopy assisted technique. The aim of this report is to emphasize the importance of fascial closures of trocar sites in order to significantly decrease postoperative morbidity.

Case report

A 31 years old female presented with a classic clinical picture of acute appendicitis. She underwent an uneventful laparoscopic appendicectomy. A 12 mm trocar was used at the umbilical port. On Postoperative day three, the patient developed abdominal distension, crampy abdominal pain, nausea and bilious vomiting. Her white cell count increased to 16,500/mm³, and CRP was 145. X-ray abdomen showed dilated small bowel with multiple air fluid levels. CT scan showed a herniated loop of small bowel into the trocar site with small bowel obstruction. Laparoscopy was done to confirm the Richter''s hernia into trocar site with small bowel obstruction. The bowel loop could not be reduced laparoscopically. Limited exploration of the trocar site confirmed findings with necrosis of the antimesenteric portion of the small bowel. A limited bowel resection and anastomosis was performed. The patient had an uneventful recovery.

Conclusion

Most port site hernias present within 10 days of the primary procedures, delayed hernias have been reported. CT scan is a helpful adjunct to differentiate port site hematoma from incarcerated small bowel. The knowledge of such a complication and its early diagnosis are important to avoid complications.     

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.     

Chilaiditi's syndrome associated with colonic volvulus and intestinal malrotation—A rare case

INTRODUCTION

Chilaiditi''s syndrome (symptomatic hepatodiaphragmatic interposition of the colon) is an exceptionally rare cause of bowel obstruction and may present difficulty in diagnosis and management. This is the first reported case of colonic volvulus occurring in Chilaiditi''s syndrome in association with intestinal malrotation and this case study describes its successful management.

PRESENTATION OF CASE

An 18 year old male presented as an emergency with vague abdominal pain and a past history of gastroschisis repair with intestinal malrotation. CT scanning showed a closed loop obstruction due to a volvulus of the colon herniating under the falciform ligament. The patient was successfully treated by surgical reduction of the hernia, anatomical correction of the malrotation and caecopexy with a tube caecostomy. At six month follow up the patient was well and asymptomatic.

DISCUSSION

In nine of the previously reported cases of Chilaiditi''s syndrome with colonic volvulus, treatment was by partial colonic resection of which a third underwent stoma formation. One patient died as a consequence of anastomotic leak following primary anastomosis. We therefore suggest an alternative approach to management.

CONCLUSION

Chilaiditi''s syndrome with colonic volvulus in association with intestinal malrotation has not previously been described. As there is no consensus in the literature as to how to manage such a case we suggest that reduction of the volvulus, anatomical correction of the malrotation and fixation of the caecum by tube caecostomy results in a successful outcome. This approach avoids the need for colonic resection and possible stoma formation.
