The authors studied the data concerning 101 patients who had undergone erroneous laparotomy for suspected acute surgical disease; these accounted for 0.4% of all the patients who were operated on for emergency indications in the same period. Eleven patients died. The operation was undertaken for an erroneous diagnosis of acute appendicitis (32 patients), acute cholecystitis (18), perforating gastric ulcer (15), peritonitis of unknown etiology (14), acute intestinal obstruction (5), strangulated hernia (3), destructive pancreatitis (3), tumor of the large intestine complicated by obstruction (3), abdominal abscess (2), thrombosis of the mesenteric vessels (1), ovarian apoplexy (1), closed abdominal trauma with injury to the viscera (4 patients). Diseases simulating the clinical picture of "acute abdomen" but not requiring an emergency operation were as follows: female reproductive (20 patients), pancreatic (11), renal diseases (11), hepatitis, cirrhosis of the liver (10), cardiovascular (9), pulmonary diseases (5), mesoadenitis (5), Crohn's disease (3), chronic colitis (3), carcinomatosis of the peritoneum (3), herpes zoster (3), and other diseases and injuries (20 patients). The main causes of the diagnostic and tactical errors were objective difficulties in the differential diagnosis due to similar symptomatology, as well as errors in the examination of the patient and haste in making a decision to make an operation.

Primary appendiceal adenocarcinoma is rare, with fewer than 300 reported cases. This report reviews 23 cases of appendiceal adenocarcinoma at Butterworth Hospital from 1968 to 1985. Clinical presentation, operative findings, treatment, and length of survival were recorded. Common clinical presentations included acute appendicitis and progressive abdominal distention. This disease was frequently an incidental finding during unrelated elective surgery and was often associated with other primary malignancies. Surgical treatment included appendectomy, right hemicolectomy, and interval hemicolectomy after initial appendectomy. Improved survival was noted in patients who had localized and noninvasive disease. Prognosis was most closely related to tumor grade. No patient who had localized, well-differentiated tumor died from the disease or had evidence of tumor recurrence after surgical treatment. All patients with poorly differentiated tumors died from widespread carcinomatosis. Appendectomy appears to be sufficient treatment for well-differentiated, localized, mucus secreting adenocarcinomas of the appendix.

Indications and contraindications to laparoscopic surgery continue to be refined. Laparoscopic appendectomy for acute appendicitis is frequently selected by patients and surgeons, and clinical studies show it to be a reasonable alternative. In this case study, laparoscopic surgery was used to resect an appendiceal mucocele caused by a nonperforated mucinous adenocarcinoma. Implants of mucinous tumor were found widely disseminated on peritoneal surfaces at laparotomy 9 months later. As a result of this case study, the authors suggest that when an appendiceal mucinous tumor is encountered at laparoscopy, a special situation requiring totally atraumatic appendectomy is indicated. This clinical situation should be considered an indication for conversion to open appendectomy. All appendiceal tumors, including the most benign-appearing adenomas, can result in diffuse peritoneal implantation. This is the first report of an appendiceal mucinous tumor resected by laparoscopy associated with subsequent diffuse peritoneal carcinomatosis. This patient presentation reaffirms that dissemination of cancer may be associated with laparoscopic resection of structures containing a malignancy.

We are reporting a rare case of peritoneal implanted hepatocellular carcinoma with rupture after transarterial chemoembolization mimicking acute appendicitis. A 45-year-old male patient presented with fever and manifestations of acute appendicitis. He received transarterial chemoembolization for hepatocellular carcinoma two months before. Emergent exploratory laparotomy revealed a normal appendix, a ruptured nodule located at the serosal surface of the terminal ileum with hemoperitoneum, and ruptured hepatocellular carcinoma at the junction of segments 4 and 8 of the liver. There was no peritoneal carcinomatosis, direct invasion to the surrounding tissue, or lymph node involvement. Postoperative course was uneventful. Histopathological examination of the resected nodule revealed metastatic hepatocellular carcinoma.

We report a case of a male 64 years old with acute abdomen who was operated with the presumptive diagnosis of complicated acute appendicitis. However the patient had black stools for two months, associated with epigastric pain. Endoscopic diagnosis was: Advanced Gastric Cancer: Borrmann II. Histology was informed as: Infiltrating adenocarcinoma intestinal type middlingly differentiated. Surgery findings were: peritonitis with perforated appendicitis in its base: Free coprolites and carcinomatosis. Histology was reported as: ulcerated mucous in caecal appendix, necrosis and perforation of the muscular wall in the base. Mesentery samples were informed with fat tissue involvement by infiltration of tubular adenocarcinoma.middlingly differentiated, suitable with primary gastric cancer.

We report a case of acute appendicitis due to recurrent metastatic gastric adenocarcinoma involving only appendix, without the evidence of abdominal carcinomatosis 2 years after initial diagnosis of the primary gastric lesion. This case, in contrast to other previously reported cases that carried a dismal prognosis, had survived without tumour recurrent for more than 1 year after appendectomy, while this report was made.

To the best of our knowledge, the formation of a retroperitoneal abscess due to acute appendicitis shortly after administration of chemotherapy for lung cancer has not been previously reported. This is the case report of a 59-year-old male who was admitted to the Mito Medical Center (Mito, Japan) and diagnosed with lung adenocarcinoma with pleuritis carcinomatosis. Although no distant metastasis was identified, combination chemotherapy with cisplatin and pemetrexed was administered. Nine days after initiating chemotherapy, the patient developed right lower quadrant abdominal pain and high fever. Computed tomography (CT) of the abdomen and pelvis revealed the collection of gas and fluid in the retroperitoneum adjacent to the cecum. The abscess was locally drained; however, the infection continued to spread, with subsequent development of a scrotal abscess. Consequently, appendectomy was performed. The patient recovered well and the lung adenocarcinoma was treated with additional courses of chemotherapy following the remission of the local inflammation. Retroperitoneal abscess due to acute appendicitis is an unusual finding; however, this rare complication should be considered during or shortly after chemotherapy in patients with lung cancer.

Pseudomyxoma peritonei (PMP) is an uncommon clinical finding describing the intraperitoneal accumulation of abundant mucinous, jelly-like material. This entity may represent a spectrum of diseases ranging from mucinous ascites, commonly associated with ruptured epithelial tumours of the appendix, to frank mucinous carcinomatosis. In cases of appendiceal origin, the patient may present with signs and symptoms of acute appendicitis, and thus careful diagnosis must be made in order to correctly and appropriately guide management. This may include a combination of surgical debulking with or without intraperitoneal or systemic chemotherapy. We present a 52-year-old woman with a 4-month history of abdominal pain and distension with a previous appendicectomy 19 years earlier. Radiological and pathological investigations diagnosed a probable PMP secondary to ruptured appendicitis many years ago. We describe her unique case, with emphasis on length of time to diagnosis and clinical management by surgical cytoreduction alone.
