The etiology of intestinal obstruction (I.O.) has changed markedly since the beginning of this century. In this series, the authors studied 121 cases of I.O. treated surgically; adhesions were the commonest cause of high intestinal obstruction, accounting for 43.03 percent in a total of 79 patients, with hernia being the obstruction lesion in 16.45 percent. Colo-rectal cancer were the commonest cause of low intestinal obstruction accounted for 73.81 percent, with volvulus of the sigmoid colon in 14.28 percent. Complications occurred in 15.7 percent of patients following operative intervention; wound infection was the most common postoperative complication. The overall operative mortality was 9.09 percent.
Unusual infections associated with colorectal tumors may, in some instances, be the sole clue to presence of malignancy. The infections are either related to invasion of tissues or organs in close proximity to the tumor or secondary to distant seeding by transient bacteremia arising from necrotic tumors. The authors present one case of spontaneous crepitant cellulitis in the lower abdominal wall, associated with sigmoid tumor. The patient had abdominal pain in the left iliaca fossa, fever and skin necrosis of the lower abdominal wall in the last 4 hours. At surgery they performed debridement and excision of necrotic tissue (lower abdominal wall) and partial sigmoidectomy with sigmoid colostomy. The patient died 9 months after initial surgery. A study of tumor mass revealed an adenocarcinoma. The presence of crepitant cellulitis in a lower abdominal wall should result in a search for bowel perforation.
The intraoperative cholangiography was carried out in 361 patients with gallstone disease. In 293 (81.16%) patients cholangiography was normal, in 68 (18.83%) was abnormal. Thirty-six (9.97%) patients had pre-operative asymptomatic common bile duct calculi and 20 (5.54%) patients had confirmed suspect of common bile duct calculi during cholangiography. Twelve (3.32%) patients were false-positive and one (0.27%) was false-negative. It is discussed the value of routine intraoperative cholangiography in patients with gallstone disease.
A total or nearly total gastrectomy was performed in 30 patients with adenocarcinoma of the stomach. The continuity of the alimentary tract was restored by end-to-side esophagojejunostomy or gastrojejunostomy using a Roux-Y and all the cases had one layer extramucosa suture with 3-0 mononylon. The complications were: one case of left subphrenic abscess; one case of anastomotic leakage (esophagojejunum anastomosis); 2 cases of abdominal wound infection. Surgical mortality was 0%.
The authors present one case of intestinal obstruction by volvulus of the cecum. The patient had abdominal pain for 4 days. This pain was colicky in nature and of greatest in density in the left iliac fossa. He was nauseated, had anorexia, and had been vomiting. Abdominal distension was present. Plain-roentgenogram of the abdomen showed an enormously distended gas-filled intestinal loop in the upper abdomen just to the left of midline. At surgery there was volvulus of the cecum located in the upper abdomen to the left of midline. The cecum was viable and was relocated in the right lower quadrant and secured to the antero-lateral abdominal wall (cecopexy). The patient made a good postoperative recovery.
