Subacute intestinal obstruction: an enigma revisited.

Sixty-three patients presenting with subacute intestinal obstruction (SAIO) were studied. Thirty (47.6%) reported recurrent symptoms. Exaggerated bowel sound, visible/palpable bowel loops, distention of abdomen and abdominal lumps were observed in 60.3%, 28.5%, 25.3% and 19.0% patients, respectively. Thirty (47.6%) required emergency laparotomy. Investigations revealed lesions requiring surgery in 14 of 33 patients which were relieved with conservative treatment. The accuracy of ultrasonography, contrast enhanced computed tomography (CECT) scan and diagnostic laparoscopy was 57.1%, 100% and 100%, respectively. Ileum was the most common site of obstruction (79.5%). Adhesions and small intestinal strictures were the two most frequent cause of obstruction seen in 31.8% and 27.2%, respectively. Tuberculous pathology was demonstrated in 23 (52.2%). Previous abdominal surgery was found to be the only predictor of the success of conservative treatment (13/19 versus 7/44). All patients of SAIO, whose symptoms were relieved with conservative treatment, and who do not have history of abdominal surgery, should be subjected to CECT and/or diagnostic laparoscopy in order to discover the underlying cause of the obstruction. When these diagnostic modalities are not available, laparotomy is an effective alternative for this group of patients.

Emphysematous pyelonephritis in a non-diabetic patient with non-obstructed kidney: an unknown entity.

Emphysematous pyelonephritis (EPN) is an acute necrotizing infection with evidence of gas inside the kidney, perinephric space, and/or urinary collecting system. This condition is usually encountered in an obstructed urinary system of diabetics or immunocompromised patients and carries poor prognosis. The gold standard for early diagnosis is computed tomography (CT) of the abdomen. Percutaneous/surgical drainage and urgent or delayed nephrectomy are the available treatment options. We report one case of EPN, which was diagnosed in an immunocompetent non-diabetic man with a non-obstructed urinary system.

Diverse presentation of spontaneous rupture of urinary bladder: review of two cases and literature.

The objective of the study was to highlight diagnostic dilemmas and suggest pointers toward early diagnosis of spontaneous rupture of urinary bladder based on case study of 2 patients diagnosed as a case of spontaneous rupture of urinary bladder. A 26-year-old man presented with painless progressive abdominal distension of 1-week duration. In absence of acute abdominal symptoms and signs, the diagnosis of chronic liver disease with ascites was entertained. Peritoneal fluid aspirate demonstrated high urea and creatinine levels. Computed tomographic (CT) scan of abdomen suggested urinary bladder rupture, which was further confirmed by CT cystogram. Another 34-year-old man presented with acute abdominal pain, hematuria, and features of peritonitis. There was no history of trauma. Foley catheterization revealed blood-stained urine. Ultrasonography abdomen suggested urinary bladder rupture, which was again confirmed by CT cystogram. Both patients made uneventful recovery after repair of bladder perforation. Spontaneous rupture of urinary bladder is extremely rare with only very few reports available in literature. High creatinine levels in the peritoneal fluid aspirate of the first patient and the blood-stained urine in the second patient were pointers toward possibility of urinary bladder rupture. Rupture of urinary bladder should always be considered in differential diagnosis of patients presenting with free fluid in abdomen/peritonitis, decreased urine output, hematuria and in whom increased level of urea/creatinine are detected in serum and/ or peitoneal fluid aspirate.

Retroperitoneal vascular malformation mimicking incarcerated inguinal hernia.

A 30-year-old man presented to the Department of Surgery with a painful groin swelling on right side. Exploration revealed a reddish-blue hemangiomatous mass in the scrotum extending through inguinal canal into the retroperitoneum. On further dissection swelling was found to be originating from right external iliac vein. The swelling was excised after ligating all vascular connections. The histopathological examination of excised mass confirmed the diagnosis of venous variety of vascular malformation. This is the first reported case of vascular malformation arising from retroperitoneum and extending into inguinoscrotal region, presenting as incarcerated inguinal hernia.

Five patients with emphysematous pyelonephritis.

Emphysematous pyelonephritis is an acute necrotizing infection of the renal parenchyma, resulting in presence of gas within either in the collecting system or perinephric space. We herein report our experience with 5 cases of emphysematous pyelonephritis in 2 men and 3 women managed by broad spectrum antibiotics, supportive measures including hemodialysis (2 patients), ureteral stenting (2 patients), surgical drainage of perinephric collection (1 patient), and control of diabetes mellitus (4 patients). Four patients were discharged after a mean hospital stay of 18 days. A nondiabetic male patient with a nonobstructed kidney died on the second postoperative day due to persistent septicemia despite nephrectomy. Emphysematous pyelonephritis is a potentially fatal disease requiring careful and prompt diagnosis and individualized rational therapy. Ureteropelvic stenting should be used for drainage of pent-up collections as a lifesaving measure through relieving the obstruction. Perinephric fluid collection should be drained either percutaneously or surgically.
