Gangrenous appendicitis in Amyand's hernia: Surgical approach under local anesthesia. Case report and review of the literature

Internal hernia after trans-abdominal preperitoneal (TAPP) hernia repair: A case report

INTRODUCTION

Hernia repair is a common procedure performed by general surgeons. Introduced in 1990s, the use of laparoscopic hernia repair has recently increased and, consequently, rare complications previously unknown have been reported.

PRESENTATION OF CASE

A 43-years-old male patient who underwent a transabdominal preperitoneal patch plasty (TAPP) procedure for symptomatic bilateral inguinal hernia. On the sixth postoperative day, the patient was admitted for small bowel obstruction (SBO) and underwent reoperation; the central portion of the peritoneal suture in the left inguinal region was lacerated and a hole in the peritoneum had performed a hernia orifice, causing small bowel occlusion by preperitoneal herniation. After the hernia was released, the peritoneum was closed again and the surgery was completed.

DISCUSSION

SBO after TAPP procedure is a rare complication and should be considered in patients with abdominal pain and vomiting after TAPP procedure.

CONCLUSION

This complication can be prevented with appropriate peritoneal closure techniques and treated with early laparoscopic surgery.

Amyand's hernia presented with strangulated and perforated appendicitis: A case report

INTRODUCTION

Amyand's hernia (AH) is a rare condition in which the vermiform appendix is incarcerated within the inguinal hernia (IH) sac. Although infrequent, it may become inflamed or perforated and can typically be diagnosed either intraoperatively or through radiographic findings.

PRESENTATION OF CASE

A 77-year-old male presented to the emergency room with constipation, fever, and an irreducible right inguinal bulge accompanied by slight localized discomfort that had persisted for ten days. Clinical examination was unremarkable, while ultrasound revealed a non-ischemic small bowel loop and a right testicular hydrocele, leading to a primary diagnosis of incarcerated IH. The patient was subsequently admitted for surgery, during which AH was confirmed. The appendix was inflamed, enlarged, and perforated, with localized abscess and internal inguinal ring stenosis. Subsequently, the surgical treatment involved appendectomy and hernia repair.

DISCUSSION

According to the appendix condition, four subtypes of AH can be encountered, with type III -perforated appendicitis- being the focus of this report. In this case report, inguinal ring stenosis was the underlying cause of complications besides the unusual presentation features that were also attributed to adhesions that prevented peritoneal involvement.

CONCLUSION

Surgeons should consider AH in the differential diagnosis of inguinal swelling and be familiar with the surgical management approach in the incidental event of AH during surgery.

Complicated appendiceal diverticulitis a extremely rare cause of acute abdomen: A case report and literature review

INTRODUCTION AND IMPORTANCE

Appendiceal diverticulitis (AD) represents a rare cause of acute abdomen. Diagnosis of AD is a challenge because of its rarity and resemblance to other ileocecal diseases like as cecal diverticulitis (CD) and acute appendicitis (AA). Preoperative imaging can be useful to aid diagnosis. Surgery represents the correct treatment of AD.

CASE PRESENTATION

A 48-year-old Caucasian male presented to the Emergency Department with a two-day history of right lower quadrant (RLQ) abdominal pain and fever. Physical examination revealed RLQ abdominal pain and rebound tenderness with muscle guarding. Laboratory tests reported high levels of C-reactive protein and neutrophilic leukocytosis. Abdominal computed tomography(CT) scan showed findings of AA and a thin-walled 5 mm appendiceal diverticulum. The patient underwent laparoscopic appendectomy. The postoperative course was uneventful, the patient was discharged on the 5th postoperative day in a stable condition. Gross anatomy confirmed the presence of appendiceal diverticulum in the distal appendix on the mesenteric border. Histopathological examination revealed an inflamed and perforated appendiceal pseudo-diverticulum with surrounding AA and peri-appendicitis.

CLINICAL DISCUSSION

Appendiceal diverticulosis is an uncommon entity, classified as congenital or acquired based on the number of appendiceal layers herniating through the normal wall. Two thirds of diverticula will develop acute or chronic diverticulitis that can lead to several complications some of which can be life-threatening.

CONCLUSION

AD is a rare surgical emergency and represents often an overlooked diagnosis. Early diagnosis and treatment are crucial for reducing morbidity and mortality Appendectomy represents a safe and appropriate treatment of AD.

Hidden appendix: A case report and literature review of perforated acute appendicitis masquerading as acute cholecystitis

Introduction

Acute appendicitis of the subhepatic appendix is uncommon, and a preoperative diagnosis is difficult without a thorough understanding of the various anatomical locations. Cross-sectional imaging is indispensable for prompt diagnosis and subsequent treatment. Surgery is the standard treatment for perforated appendicitis in the subhepatic region. In this study, we present a case of subhepatic appendicitis with an unusual presentation.

Case presentation

A 28-year-old man presented to our emergency department with a 3-day history of diffuse right abdominal discomfort, diarrhea, fever, and vomiting. Physical examination revealed rebound soreness and guarding in the right upper and lower quadrants. Laboratory tests revealed high levels of C-reactive protein and serum bilirubin and neutrophilic leukocytosis. Abdominal computed tomography revealed an undescended cecum and a subhepatic appendix with an intraluminal appendicolith, fat stranding, and peri-appendiceal fluid. The patient underwent open exploration and appendicectomy, during which the subhepatic perforated appendix was excised. The patient's recovery was uneventful.

Discussion

Atypical presentations may indicate an unusual anatomical placement of the appendix. Preoperative diagnosis using cross-sectional computed tomography imaging and a thorough understanding of these situations frequently result in early diagnosis and expeditious surgical care.

Conclusion

Surgical crises resulting from aberrant anatomical variations of the appendix constitute a distinct diagnostic challenge. A strong index of suspicion for this uncommon presentation permits early surgical intervention and prevents delay-induced morbidity/mortality.

•

Appendicitis classically presents with right iliac fossa pain.

•

Anomalous positions of the appendix can give rise to clinical challenges.

•

Perforation in subhepatic appendicitis masquerades as acute cholecystitis.

•

Undescended cecum could give rise to the rare anatomical position of the appendix.

Subhepatic perforated acute appendicitis in a patient with midgut malrotation: A case report and review of the literature

INTRODUCTION AND IMPORTANCE

Subhepatic acute appendicitis (SHAA) is a very rare cause of acute abdomen, developing in association with two types of congenital anomalies like as midgut malrotation (MM) and maldescent of the caecum. Preoperative diagnosis of SHAA is a challenge because of its rarity and atypical presentation. Imaging may be helpful for determining the correct diagnosis. Surgery represents the standard treatment of SHAA.

CASE PRESENTATION

A 25-year-old Caucasian male presented to the Emergency Department with a one-day history of right lower quadrant (RLQ) abdominal pain, nausea and vomiting. Physical examination revealed RLQ abdominal rebound tenderness with guarding. Laboratory tests reported high levels of C-reactive protein and neutrophilic leukocytosis. Abdominal contrast-enhanced computed tomography showed a SHAA with intraluminal appendicolith, fat infiltration and pelvic fluid collection in a patient with MM. The patient underwent laparoscopic appendectomy: a retrocaecal subhepatic phlegmonous and perforated appendicitis was sectioned and removed with drainage of pelvic abscess. The postoperative course of the patient was uneventful.

CLINICAL DISCUSSION

SHAA is characterized by anatomical variation of appendix and atypical presentation. Preoperative clinical diagnosis of SHAA is very difficult and imaging may be helpful for determining the correct diagnosis, as well as confirming MM or maldescent of the caecum. Laparoscopic appendectomy represents the correct treatment of SHAA.

CONCLUSION

SHAA is a rare surgical emergency that should be considered in the differential diagnosis of patients with RLQ abdominal pain. Preoperative diagnosis needs a high index of suspicion and is facilitated by imaging. Surgery represents the appropriate treatment of SHAA.

Left-sided acute appendicitis in a patient with situs viscerum inversus totalis: A case report

INTRODUCTION AND IMPORTANCE

Left-sided acute appendicitis (LSAA) is a very rare cause of acute abdomen, developing in association with two types of congenital anomalies like as situs viscerum inversus (SVI) and midgut malrotation (MM). Preoperative diagnosis of LSAA is a challenge because of its rarity and atypical presentation. Imaging may be helpful for determining the correct diagnosis. Surgery represents the standard treatment of LSAA.

CASE PRESENTATION

A 67-year-old Caucasian male with presented to the Emergency Department with a two-day history of left lower quadrant (LLQ) abdominal pain, nausea, vomiting, diarrhea and fever. Physical examination revealed LLQ abdominal rebound tenderness with guarding. Laboratory tests reported high levels of C-reactive protein and neutrophilic leukocytosis. Abdominal contrast-enhanced computed tomography showed a LSAA with intraluminal appendicoliths, fat infiltration and pericecal fluid collection in a patient with SVI. The patient underwent laparoscopic appendectomy: a gangrenous and perforated appendicitis was sectioned and removed with drainage of pericecal abscess. The postoperative course of the patient was uneventful.

CLINICAL DISCUSSION

LSAA is characterized by anatomical variation of appendix and atypical presentation. Preoperative clinical diagnosis of LSAA is very difficult and imaging may be helpful for determining the correct diagnosis, as well as confirming SVIT or MM. Laparoscopic appendectomy represents the correct treatment of LSAA.

CONCLUSION

LSAA is a rare surgical emergency that should be considered in the differential diagnosis of patients with LLQ abdominal pain. Preoperative diagnosis of LSAA needs a high index of suspicion and is facilitated by imaging. Surgery represents the appropriate treatment of LSAA.

Complicated Littre's umbilical hernia with normal Meckel's diverticulum: A case report and review of the literature

INTRODUCTION AND IMPORTANCE

A Littre's hernia (LH) is defined by the presence of Meckel's diverticulum (MD) in any kind of hernia sac. Preoperative diagnosis of LH is a challenge because of its rarity and the absence of specific radiological findings and clinical presentation. Surgery is the appropriate treatment of complicated LH that is an extremely rare condition with approximately 50 cases reported in the literature over the past 300 years.

CASE PRESENTATION

A 46-year-old Caucasian female was admitted to the Emergency Department with a two-day history of abdominal pain. Physical examination revealed an irreducible and painfull mass in umbilical region. Abdominal computed tomography scan showed the protrusion of greater omentum and small bowel loop through the umbilical ring. Laboratory tests were unremarkable. After diagnosis of strangulated umbilical hernia, the patient underwent exploratory laparotomy: the irreducible umbilical hernial sac was opened with presence of incarcerated and strangulated omentum and uncomplicated MD. Resection of incarcerated and ischemic greater omentum alone was performed. The postoperative course of patient was uneventful.

CLINICAL DISCUSSION

Meckel's diverticulum (MD) is a vestigial remnant of the omphalomesenteric duct, representing the most common congenital malformation of the gastrointestinal tract. Preoperative diagnosis of LH is very difficult and surgery represents the correct treatment of complicated LH.

CONCLUSION

LH represents an extremely rare complication of MD difficult to diagnose and suspect because of the lack of specific radiological findings and clinical presentation. Surgery represents the appropriate treatment of abdominal wall hernias and complicated MD.
