Suprarenal IVC reconstruction is justified in selected cases, with good functional results. When the renal confluence is resected along with the IVC, renal vein reconstruction may be needed to avoid acute renal failure. The oncologic results of such extensive resections are poor. Adjuvant therapy should be evaluated.
Spontaneous haemorrhage associated with chronic pancreatitis in 17 patients was related to a pseudocyst in 15 (88 per cent) patients and to pancreatic lithiasis (one patient) or to infarction-rupture of the spleen (one patient). Bleeding was massive in six patients and intermittent in 11. It resulted from erosion of the gastroduodenal or the splenic artery in four patients. Bleeding into the pancreatic duct occurred in four patients and erosion of the duodenum by a bleeding pseudocyst in five. Haemorrhage was confined to a pseudocyst in six patients and was intraperitoneal in two. Of the 15 patients with bleeding pseudocysts, ten underwent primary pancreatic resection (eight proximal and two distal pancreatectomies) with no mortality but four had early complications. Four of the five patients who underwent transcystic ligation of bleeding vessels and pseudocyst drainage had postoperative complications: one died from sepsis and liver failure and three underwent reoperation for severe postoperative bleeding. Of these, two had proximal pancreatic resection with one death. The third patient had further suture ligation and external drainage. The overall postoperative mortality rate was 12 per cent and following emergency surgery 33 per cent. Favourable results were achieved in two-thirds of patients when the primary operative strategy could be directed towards the control of bleeding and removal of the affected pancreatic segment. Primary pancreatic resection, although technically demanding in the presence of haemorrhage, is recommended whenever possible for the treatment of bleeding pancreatic pseudocysts and pseudoaneurysms associated with chronic pancreatitis.
The intra- and early postoperative courses of 142 consecutive patients who underwent liver resections using vascular occlusions to reduce bleeding were reviewed. In 127 patients, the remnant liver parenchyma was normal, and 15 patients had liver cirrhosis. Eighty-five patients underwent major liver resections: right, extended right, or left lobectomies. Portal triad clamping (PTC) was used alone in 107 cases. Complete hepatic vascular exclusion (HVE) combining PTC and occlusion of the inferior vena cava below and above the liver was used for 35 major liver resections. These 35 patients had large or posterior liver tumors, and HVE was used to reduce the risks of massive bleeding or air embolism caused by an accidental tear of the vena cava or a hepatic vein. Duration of normothermic liver ischemia was 32.3 +/- 1.2 minutes (mean +/- SEM) and ranged from 8 to 90 minutes. Amount of blood transfusion was 5.5 +/- 0.5 (mean +/- SEM) units of packed red blood cells. There were eight operative deaths (5.6%). Overall, postoperative complications occurred in 46 patients (32%). The patients who experienced complications after surgery had received more blood transfusion than those with an uneventful postoperative course (p less than 0.001). The length of postoperative hospital stay was also correlated with the amount of blood transfused during surgery (p less than 0.001). On the other hand, there was no correlation between the durations of liver ischemia of up to 90 minutes and the lengths of postoperative hospital stay. The longest periods of ischemia were not associated with increased rates of postoperative complications, liver failures, or deaths. There was no difference in mortality or morbidity after major liver resections performed with the use of HVE as compared with major liver resections carried out with PTC alone, although the lesions were larger in the former group. It is concluded that the main priority during liver resections is to reduce operative bleeding. Vascular occlusions aim at achieving this goal and can be extended safely for up to 60 minutes.
From 1953 to 1982, 257 patients with complete rectal prolapse were operated upon. To the procedure described by Orr, we have added mobilization of the rectum prior to its suspension and eliminated the pouch of Douglas, and nylon strips have been used for suspension in most patients. There were 57 male and 200 female patients. Ages ranged from 11 to 90 years. Sixty-one patients had already undergone surgery for rectal prolapse with another procedure and prolapse had recurred. The postoperative course was uneventful in 96 per cent of patients. Two patients, aged 79 to 83 years, died of cardiac failure. Follow-up of 115 patients ranged from five to 23 years. Recurrent rectal prolapse was observed in 4.3 per cent of the patients in whom nylon strips were used to suspend the rectum. In 136 patients anal incontinence was associated with rectal prolapse. Normal continence was restored in 84.1 per cent of 107 patients with rectopexy alone and in 64.2 per cent of 14 patients who underwent rectopexy and anal sphincter repair. It is concluded that rectopexy to the promontory with nylon strips after mobilization of the rectum is a safe and efficient procedure for the treatment of rectal prolapse.
