Ileosigmoid knot is rare yet life-threatening condition caused by acute double loop intestinal obstruction. Preoperative diagnosis is difficult and it is associated with high morbidity and mortality. We present one such patient we encountered and outline our management, and discuss the surgical options available.

Chronically undernourished patients (n = 10) undergoing elective abdominal surgery were assessed with regard to their energy expenditure and urinary nitrogen loss. These measurements were made for 1 week after the surgery, and stress factors for each parameter were computed. The responses of the chronically undernourished patients were compared to those of relatively well nourished patients (n = 10) undergoing comparable surgeries. It was found that the postoperative resting energy expenditure (REE) of the chronically undernourished patients was not significantly elevated when compared to their preoperative values (mean +/- SEM): 1210.66 +/- 88.13, 1354.91 +/- 86.61, 1215.09 +/- 89.68, and 1188.23 +/- 86.61 kcal/day preoperatively and on postoperative days 1, 4, and 8, respectively. On the other hand, the postoperative REE of the controls was significantly elevated (p < 0.05) over their baseline values: 1357.18 +/- 70.81, 1574.66 +/- 100.35, 1502.89 +/- 109.44, and 1477.23 +/- 83.52; kcal/day, respectively, for the same days. The stress factors for the controls were higher than those for the undernourished (1.16 versus 1.12, 1.11 versus 1.00, and 1.09 versus 0.98 on postoperative days 1, 4, and 8, respectively). The urinary nitrogen excretion in both groups (for the 4 days) was not significantly elevated over baseline (6.23 +/- 0.87, 7.72 +/- 0.71, 8.36 +/- 0.87, and 8.04 +/- 1.56 grams/day in the undernourished; and 7.59 +/- 1.03, 9.57 +/- 1.33, 9.49 +/- 1.03, and 8.67 +/- 0.76 grams/day in the controls. The stress factors for nitrogen excretion were slightly higher in the undernourished group.(ABSTRACT TRUNCATED AT 250 WORDS)

Generalized peritonitis in patients over the age of 50 years is a common surgical emergency. This is a retrospective analysis of 98 cases managed surgically. Duodenal ulcer perforations, necrotizing enteritis, acute cholecystitis with perforation and small bowel perforations were the common causes. Most of them presented late, and many had associated conditions. Re-look laparotomies had a definite role to play. While there is significant decrease in the number of typhoid and tubercular peritonitis, there appears to be an increase in the incidence of necrotizing enteritis and acute cholecystitis.

The association of the atrophy-hypertrophy complex in monolobar Caroli’s disease (Type I) is reported in a 30 year old male who presented with recurrent cholangitis. Ultrasound and CT scan showed localised, right sided, saccular biliary dilatation in a normal sized liver. Severe right lobar atrophy was detected at operation and the resected right lobe weighed only 140 gms. Distortion of the hilar vascular anatomy and posterior displacement of the right hepatic duct orifice were problems encountered at surgery.
