Coinfection with hepatic cystic and alveolar echinococcosis with abdominal wall abscess and sinus tract formation: A case report.

BACKGROUND: Hepatic cystic and alveolar echinococcosis coinfections, particularly with concurrent abscesses and sinus tract formation, are extremely rare. This article presents a case of a patient diagnosed with this unique presentation, discussing the typical imaging manifestations of both echinococcosis types and detailing the diagnosis and surgical treatment experience thereof. CASE SUMMARY: A 39-year-old Tibetan woman presented with concurrent hepatic cystic and alveolar echinococcosis, accompanied by abdominal wall abscesses and sinus tract formation. Initial conventional imaging examinations suggested only hepatic cystic echinococcosis, but intraoperative and postoperative pathological examination revealed the coinfection. Following radical resection of the lesions, the patient's condition improved, and she was discharged soon thereafter. Subsequent outpatient follow-ups confirmed no recurrence of the hydatid lesion and normal surgical wound healing. Though mixed hepatic cystic and alveolar echinococcosis with abdominal wall abscesses and sinus tract formations are rare, the general treatment approach remains consistent with that of simpler infections of alveolar echinococcosis. CONCLUSION: Lesions involving the abdominal wall and sinus tract formation, may require radical resection. Long-term prognosis includes albendazole and follow-up examinations.

An Anterior Abdominal Abscess as the Initial Presentation of a Perforated Duodenal Ulcer: A Case Report.

Duodenal perforation most commonly presents with life-threatening symptoms of acute abdomen. However, in rare cases, a perforation may have an indolent course due to subclinical progression, and the patient may present with complications at the first visit. We present a case of an anterior abdominal abscess as the initial presentation of a duodenal perforation in a 65-year-old female with no pre-morbidities. The patient presented with a painful mass in the right upper quadrant associated with fever. Physical examination revealed a tender, erythematous swelling in the right hypochondrium and lumbar regions with no signs of peritonitis. Contrast-enhanced CT (CECT) of the abdomen showed a subcapsular hepatic abscess with parietal extension, but no signs of hollow viscus perforation were visible. Empirical antibiotics were given, and incision and drainage (I&D) were performed to drain around 100 mL of pus. However, drain on postop day one demonstrated bile suggesting a hollow viscus perforation, which was confirmed by a Gastrografin study.

Recurrent Primary Abdominal Wall Abscess: A Case Report and Review of the Literature.

Primary abdominal wall abscess is extremely rare and difficult to diagnose because abdominal wall abscesses usually occur secondary to malignant tumors or inflammatory diseases. We experienced a case of an 80-year-old man with an asynchronous primary abdominal wall abscess with recurrence. Both abscesses were successfully treated with surgical drainage. A patient without any history of cancer or trauma presented to our department with right upper abdominal pain. His laboratory data showed an abnormal high inflammatory response, and computed tomography revealed a 40 × 30 mm mass formed in the rectus abdominis muscle of the upper right abdomen. The mass had no continuity with the surgical scar after cholecystectomy or intra-abdominal organs. Citrobacter diversus was detected in the culture from the mass and any epithelial components were not detected by biopsy. For the diagnosis of primary abdominal wall abscess, the patient underwent surgical drainage because antibiotic treatment was ineffective. The abscess disappeared promptly after the drainage. Thirteen months after the first treatment, another primary abdominal wall abscess was noted in the lower right abdomen. The abscess also promptly disappeared with surgical drainage. Primary abdominal wall abscess is difficult to diagnose because of its rarity. Prompt diagnosis and drainage are important to prevent exacerbation.

Gallbladder empyema: An atypical manifestation of acute cholecystitis.

INTRODUCTION AND IMPORTANCE: Acute cholecystitis is responsible for 44 % of emergency admissions to the emergency services with multiple complications such as empyema a necesitatis (EN). EN has a close relation with cholecystitis when the perforation of the gallbladder (GB) can lead to the formation of a biliary fistula. Patients can be asymptomatic, with late consultations, thus being a diagnostic challenge. Different techniques are described for cholecystitis and secondary abscess, therefore, the choice of the appropriate procedure should be the best one to reduce the high associated morbidity. CASE PRESENTATION: We present a case of an 89-year-old patient, admitted for a sensation of a mass in the right hypochondrium with abdominal pain. He was taken to the operating room, finding a vesicular plastron with piocholecyst and perforation into the abdominal wall with abscess and fasciitis. Subtotal cholecystectomy was performed laparoscopically and an open approach in the abdominal wall, drainage of the abscess and debridement, leaving a negative pressure system. CLINICAL DISCUSSION: EN affects elder patients with high rates of morbidity, also GB empyema, which is related with its perforation and posterior fistulization, its external spontaneous perforation is much less frequent. Fistulas originated from the biliary tract are well described in the literature, with low incidence. They are related with improved diagnostic investigations and earlier implemented treatment by antibiotics and surgery. CONCLUSION: Biliary EN represents a very unusual complication of acute cholecystitis, its atypical presentation represents a diagnostic challenge, with very few cases documented and high mortality rates. Its management represents a challenge for the general surgeon, finding different approaches and surgical behaviors to take.

Extraintestinal Clostridioides difficile Infection (CDI): A Recurrent Battle with Resilient Abdominal Wall Abscess.

Clostridioides (formerly Clostridium) difficile infection is a common and costly healthcare-associated infection. Extraintestinal C. difficile infection is rarely encountered, especially in isolation. We present a unique case of abdominal wall abscess presenting six months following gastrointestinal (GI) surgery. The patient was managed with computed tomography (CT) guided drainage of the abscess, placement of a drainage catheter, and aggressive broad-spectrum antibiotic treatment for a prolonged duration over multiple admissions. LEARNING POINTS: Risk factors for extraintestinal CDI include prior hospital stay, prolonged antibiotic therapy, proton pump inhibitor (PPI) use, relative state of immunodeficiency such as malnutrition and diabetes mellitus, previous abdominal surgery especially following perforation and leak of intestinal content.Presentation can be late following surgery with mesh repair (foreign body implantation) for intestinal perforation as they have high risk of colonisation, which later leads to infection.For extraintestinal CDI in the presence of a foreign body, removal is the desired course of action. But it is not always possible given the presence of comorbidities in this population, thus resulting in a prolonged course of antibiotics.

Abdominal wall abscess resembling urachal carcinoma caused by ileal diverticulitis.

Introduction: We report a rare case of abdominal wall abscess caused by ileal diverticulitis that developed along the midline below the umbilicus and resembled a urachal carcinoma. Case presentation: A 76-year-old woman with diabetes presented with abdominal enlargement below the umbilicus. Computed tomography revealed a well-enhanced mass, which was visualized on magnetic resonance imaging as a continuous mass connected to the restiform structure, extending from the umbilicus to the bladder. As the mass showed high uptake on 18F-fluorodeoxyglucose positron emission tomography, urachal carcinoma was suspected, and surgery was subsequently performed. As the tumor adhered to the ileum, partial resection of the small intestine was required. The pathological diagnosis was abdominal wall abscess associated with ileal pseudodiverticulitis. Conclusion: Although abdominal wall abscess caused by ileal diverticulitis is rare, it should be considered as a differential diagnosis of urachal carcinoma.

Successful multi-stage treatment of stoma limb perforation following Hartmann's operation report a case.

BACKGROUND: Stoma-related complications are not rare, whereas the spontaneous perforation of the stoma limb is relatively rare. Herein, we report a case of stoma limb perforation which occurred after Hartmann's operation. CASE PRESENTATION: A 50-year-old Japanese man presented to our Hospital with acute and severe abdominal pain. Abdominal computed tomography (CT) scan revealed that an abscess with free air was formed around the sigmoid colon. We performed Hartmann's operation, whereas he experienced redness, purulent discharge, and swelling around the colostomy at 10 days postoperatively. The contrast-enhanced CT scan of the abdomen revealed an abscess formation with air around the colostomy. He was diagnosed with an abdominal wall abscess due to perforation of the stoma limb. After the drainage, his symptoms were ameliorated by oral analgesics, anti-inflammatory drugs, and prophylactic antibiotic. Four months after the first operation, we performed a closedown of the sigmoid colostomy and fistula resection. The patient's postoperative course was uneventful, and he was discharged 14 days later. CONCLUSIONS: This case depicts rare complications of Hartmann's operation. Operation is usually performed in patients with stoma limb perforation. However, if they are stable and the abscess is located in their abdominal wall, they may be treated successfully using a multi-stage approach of local drainage toward the stoma wall followed by stoma closure.

Development of an abdominal wall abscess caused by fish bone ingestion: a case report.

BACKGROUND: A small percentage of patients with foreign body ingestion develop complications, which have a variety of clinical presentations. Less than 1% of cases require surgical intervention. We present a patient with an abdominal wall abscess resulting from a fish bone that pierced the cecum. The patient was treated laparoscopically. CASE PRESENTATION: A 55-year-old Japanese man presented to our hospital with a complaint of right lower abdominal pain. A physical examination revealed tenderness, swelling, and redness at the right iliac fossa. Computed tomography showed a low-density area with rim enhancement in his right internal oblique muscle and a hyperdense 20 mm-long pointed object in the wall of the adjacent cecum. Based on the findings we suspected an abdominal wall abscess resulting from a migrating ingested fish bone. He was administered antibiotics as conservative treatment, and the abscess was not seen on subsequent computed tomography. Two months after the initial treatment, he presented with the same symptoms, and a computed tomography scan showed the foreign body in the same location as before with the same low-density area. We diagnosed the low-density area as recurrence of the abdominal wall abscess. He underwent laparoscopic surgery to remove the foreign body. His appendix, and part of his cecum and the parietal peritoneum that included the foreign body, were resected. He had an uneventful postoperative course, and at 1 year after the surgery, the abdominal wall abscess had not recurred. CONCLUSIONS: An abdominal wall abscess developed in association with the migration of an ingested fish bone. We suggest that a laparoscopic surgical resection of the portion of the bowel that includes the foreign body is a useful option for selected cases.

Small bowel diverticulum complicated by enterocutaneous fistula and abdominal wall abscess - Case report.

INTRODUCTION: Small bowel diverticular disease is uncommon, representing 1-2% of general population. The ileum diverticulum is very rare, especially if it is complicated by enterocutaneous fistula with abdominal wall abscess. PRESENTATION OF THE CASE: Here, we report a case of small bowel diverticulum, ileum diverticulum with enterocutaneous fistula in a 65-year man presented with lower abdominal pain and an irreducible swelling for 5 days. DISSECTION: Diverticulosis has no exact cause, but theoretically the diverticula result from peristalsis abnormalities, intestinal dyskinesia, or high segmental intraluminal pressures. Complications of small intestinal diverticulum include bleeding, diverticulitis and its complication (e.g. fistula formation, and intra-abdominal abscess) [5]. CONCLUSION: This is considered rare and serious complication of small bowel diverticulum could occur if diagnosis is delayed.

Primary Appendicular Malignancy Presenting as Abdominal Wall Abscess with Secondary Tuberculosis Infection: an Interesting Case Report.

Cancers of the appendix are rare. Most of them are found accidentally on appendectomies performed for appendicitis. When reviewed, majority of the tumors were carcinoid, adenoma, and lymphoma. Adenocarcinomas of the appendix are only 0.08% of all cancers, and the treatment remains controversial. It can present as appendicitis or lump or abscess. Gastrointestinal tuberculosis most commonly involves the ileocecal region. Disruption of the integrity of mucosal barriers and impairment in cell-mediated immunity associated with cancerous growth are known to predispose to bacterial infection. The role of antituberculosis therapy and chemotherapy is unclear due to lacking randomized trials but seems to be accepted if there is lymph node involvement or peritoneal seeding. Here, we are reporting a 69-year-old lady presented with symptoms of abdominal wall abscess with tuberculosis infection which was then diagnosed with mucinous adenocarcinoma of the appendix. The patient was treated with incision and drainage followed by the right hemicolectomy. Up to date, she remains asymptomatic and continuing with chemotherapy.

Sertoliform Endometrioid Carcinoma of Ovary Presenting as Abdominal Wall Abscess.

Sertoliform endometrioid carcinoma (SEC) is a rare epithelial ovarian cancer which may be mistaken for sex cord tumour on microscopy. Immunohistochemistry and extensive sampling of tumour to look for areas of conventional endometrioid carcinoma are important to confirm the diagnosis of SEC. We report a case of SEC of ovary in a postmenopausal lady who presented to us with abdominal wall abscess in epigastric region.

Abdominal wall abscess secondary to spontaneous rupture of pyogenic liver abscess.

INTRODUCTION: Pyogenic liver abscess is a rare cause of hospitalization, related to a mortality rate ranging between 15% and 19%. Treatment of choice is represented by image-guided percutaneous drainage in combination with antibiotic therapy but, in some selected cases, surgical treatment is necessary. In extremely rare cases, spontaneous rupture of liver abscess may occur, free in the peritoneal cavity or in neighboring organs, an event which is generally considered a surgical emergency. PRESENTATION OF CASE: A 95-years-old woman was hospitalized with fever, upper abdominal pain, mild dyspepsia and massive swelling of the anterior abdominal wall. Computed tomography revealed an oval mass located in the abdominal wall of 12cm×14cm×7cm, in continuity with an abscess of the left hepatic lobe. Because Proteus mirabilis was detected in both the liver abscess and the abdominal wall abscess, the patient was diagnosed with a ruptured pyogenic liver abscess. After spontaneous drainage to the exterior of the hepato-parietal abscess, she was successfully treated with antibiotics alone. CONCLUSION: Pyogenic liver abscess is a serious and life-threatening illness. Abscess rupture might occur. Many authors consider this complication a surgical emergency, but the site of abscess rupture changes the clinical history of the disease: in case of free rupture into the peritoneum, emergency surgery is mandatory, while a rupture localized in neighboring tissues or organs can be successfully treated by a combination of systemic antibiotics and fine needle aspiration and/or percutaneous drainage of the abscess.

Rare Hernias Presenting as Acute Abdomen- A Case Series.

Hernia is an abnormal protrusion of an organ or tissue through a defect in its surrounding walls. It can be divided into internal, external and diaphragmatic hernias. Most of them can be asymptomatic. If they become symptomatic they can present with features of intestinal obstruction, incarceration or strangulation. In this case series we compare the incidence of these rare presentations of hernias with world literature and to warn surgeons not to cut the obstructing band in cases of internal hernias. In this case series, we review the clinical details of 7 rare presentations of hernia, who presented with various types of hernias to a tertiary care centre in Kerala over a period of one year. Of these 7 cases 6 cases were internal hernias (3 left paraduodenal hernias, 2 transmesentric hernias, and 1 pericaecal hernia) and a case of spigelian hernia above the level of umbilicus. All of them presented as acute abdomen in the emergency department. Among these 7 cases, only one case was diagnosed preoperatively. Three patients had bowel gangrene and had to undergo resection- anastomosis of the bowel. The survival rate among these cases was 100% as compared to 50% in the world literature if they had been left untreated. Even though internal hernias are a rare entity, we need to have it as a differential diagnosis in case of intestinal obstruction, in a previously non-operated abdomen.

Primary Liver Abscess with Anterior Abdominal Wall Extension Caused by Mycobacteriumtuberculosis Complex.

Tubercular liver abscess is generally secondary to some other primary foci in the body, most notably pulmonary and gastrointestinal system. To find primary tubercular liver abscess is rare, with prevalence of 0.34% in patients with hepatic tuberculosis. Abscess tracking into abdominal wall from spinal and para spinal tuberculosis is known, however primary liver tuberculosis rupturing into anterior abdominal wall has been reported only twice in literature. We report a case of 43-year-old female with direct invasion of the anterior abdominal wall from an isolated tubercular parenchymal liver abscess, caused by Mycobacterium tuberculosis complex, diagnosed primarily on smear for Acid Fast Bacilli (AFB), imaging and isolated by culture and BACTEC MGIT 960 KIT. We discuss here the diagnostic dilemma, management and outcome of primary tubercular liver parenchymal abscess with direct invasion into anterior abdominal wall.

Delayed abdominal wall abscess after abdomino-perineal resection simulating local recurrence of rectal cancer.

INTRODUCTION: We report a rare case of delayed abdominal wall abscess after abdominoperineal resection (APR) for rectal cancer. CASE DESCRIPTION: A 63-year-old woman was diagnosed with rectal cancer and received chemo-radiotherapy, followed by APR. One year after surgery, the patient complained of pain and skin redness in the lower abdomen. A low-density mass lesion with 5.9-cm diameter was found in the lower abdominal wall by computed tomography, which showed high uptake on positron-emission tomography. These findings suggested the possibilities of either delayed abscess formation or abdominal wall recurrence of rectal cancer with central necrosis. Percutaneous drainage was performed. The content was a purulent exudate, without neoplastic cells in the cytology. The lesion quickly disappeared after the drainage, and no recurrence of the tumor was observed for more than 2 years. DISCUSSION AND EVALUATION: In this case, the un-absorbable yarn, such as silk, has not been used during the operation, no foreign body was retained in the abdominal wall, and there was no associated inflammatory bowel disease. Use of neoadjuvant chemoradiotherapy was the only possible cause of delayed abscess formation in this case. CONCLUSION: In case local recurrence is suspected by imaging modalities in the postoperative of colorectal cancer, especially those with precedent chemoradiotherapy or radiotherapy, although rare, the possibility of a delayed abscess formation should also be considered.

A Case of an Abdominal Wall Abscess Associated with Spilled Gallstones: Imaging Findings and Clinical Significance

Laparoscopic cholecystectomy (LC) has been the gold standard for symptomatic gall stones for the last 20 years. The spillage of stones is reported in up to one-third of all LCs but clinical squeals caused by dropped gallstones are uncommon. We recently observed a patient with late abdominal wall abscess formation as a result of dropped gall stones after LC, who in the end, underwent open surgery because the medical therapy including antibiotics and percutaneous catheter drainage was not fully effective.

A Case of Abdominal Wall Abscess

We experienced a case of abdominal wall abscess originated from abdominal wall hematoma in 3 year old girl, who complained of abdominal pain, fever and lethargy. On admission, abdominal ultrasonography, abdominal computed tomography, and diagnostic needle aspiration were performed. Incision was made over the abscess so necrotic tissue and pus were evacuated. A nelaton catheter drain was placed into abscess cavity and, irrigation was done daily with normal saline mixed with antibiotics. Postoperative course was uncomplicated and the patient was discharged on 17th hospital day.
