[Elemental feeding into the distal segment of a temporary small bowel].

Patients who have an interruption of the small bowel with a high enterostomy usually need parenteral supply or reinfusion of chyme to maintain nutritional and electrolytic balances before restoring intestinal continuity. Ten patients (aged 28-76 years) with a terminal jejunostomy located within the first meter of jejunum were treated by infusion of an elemental diet into the distal small bowel (IEDDSB). In addition, five of these patients had an extensive small bowel resection. IEDDSB was started 32 days after operation and lasted 4 to 8 weeks. Mean daily caloric infusion was 1,732 +/- 666 kcal diluted in 2,860 +/- 808 ml; mean associated oral intake was 1,187 +/- 480 kcal/24 hr, and jejunal fecal losses averaged 3 kg per day. IEDDSB was well tolerated in 4 patients; 5 experienced transient abdominal pain or diarrhea; 1 developed severe and protracted diarrhea. Biological cholestasis was seen before IEDDSB and persisted in most patients; 1 patient developed biliary sludge. Through IEDDSB, nutritional status improved or remained satisfactory in 9 patients, and worsened in 1 patient with sepsis and a short lower intestine. Mean body weight, triceps skin fold, muscle circumference, serum albumin, serum transferrin did not change significantly. Digestive nitrogen balance performed in 6 patients showed a net absorption between 5 and 15 g/24 hr. Fluid and electrolyte balance was maintained in 9 patients and 1 received iterative intravenous saline. Digestive sodium balance showed a net absorption rate greater than 60 mmol/24 hr. in all patients, except the one who required intravenous supply. Postoperative recovery was uneventful in all patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Repeat hepatic resection for primary and metastatic carcinoma of the liver.

During the last 15 years, 19 patients underwent repeated hepatic resections for malignant lesions of the liver. The first hepatic resection had been performed four to 40 months earlier for treatment of hepatocellular carcinoma (nine patients) or hepatic metastases (ten patients), eight of which were of colorectal origin. Repeat resection was an extensive hepatectomy in six, a segmentectomy in six and a local excision in seven. In one patient, three wedge resections and, finally, hepatic transplantation were subsequently performed after an initial extended right lobectomy. The operative mortality rate was 5.2 per cent. The three year actuarial survival rate was 64 per cent after the second resection.

[Hepatectomy with total vascular exclusion. Anatomical principles based on 64 dissections].

Intra-operative hemorrhage is the main surgical risk during liver resections. Nowadays hepatectomies for large or posterior liver tumors close to the hepatocaval junction can benefit from total hepatic vascular exclusion (HVE) involving portal triad exclusion and clamping of the inferior vena cava (IVC) below and above the liver. Anatomical aspects of HVE have been studied in 64 subjects by segmental occlusive phlebographies of the IVC, injection of corrosive substances into the hepatocaval network, biometry of the retrohepatic IVC and serial sections of injected livers. A total HVE should exclude the right suprarenal and phrenic veins. Clamping of the suprahepatic IVC depends on the termination of the left inferior phrenic vein. Clamping of the subhepatic IVC must be retrohepatic: the right lobe of the liver has to be mobilized to free the right border of the retrohepatic IVC into which flows the right suprarenal vein 40 +/- 20 mm above the right renal vein and under the superior right hepatic vein. Both suprahepatic and retrohepatic clamps excluding the retrohepatic portion of the IVC (46.6 +/- 13 mm) and the hepatocaval junction should come in contact behind the IVC without overlapping.

[Reoperation in severe hepatic trauma. 30 cases].

From 1978 to 1987, thirty patients were secondarily referred to Saint-Antoine Hospital for the treatment of their hepatic trauma. Seventeen were referred because of a postoperative complication (group I) and thirteen after peri-hepatic packing (group II). In group I, transfer was decided because of hemorrhage (8 patients), sepsis (6 patients) and haemobilia (3 patients). The lesions observed in this group (hemoperitoneum, hepatic sequestrum, intrahepatic hematoma, choleperitoneum and subphrenic abscess) were often related to an incomplete assessment of hepatic damage due to an inadequate exploration and the absence of operative cholangiography. In group II, peri-hepatic packing was effective in eleven patients. The overall mortality was 16.6% (17.6% in group I and 15.4% in group II). Postoperative complications occurred in 50% of the patients (64.6% in group I and 30.7% in group II). Good exposure of the liver, operative cholangiography and, in selected cases, a direct approach to the lacerated liver with suture ligation of severed blood vessels and bile ducts are mandatory for the complete exploration and the treatment of severe hepatic trauma. Peri-hepatic packing and the transfer of the patient to a specialized center is a reliable method when the injury cannot be treated locally.

High-output external fistulae of the small bowel: management with continuous enteral nutrition.

Three hundred and thirty-five patients with high-output enterocutaneous fistulae arising from the small intestine are reported. Median fistula output was 1350 ml/24 h. Eighty-two per cent of patients were referred from other institutions. The fistula opening was associated with evisceration in 165 cases (49 per cent). One or more severity factors were present in 75.5 per cent of the patients. Patients were divided into three groups according to their initial therapy: 21 patients (6 per cent) referred in a moribund state were not operated on (non-intervention); 80 patients (24 per cent) were operated on as an emergency, and the fistula was either exteriorized or defunctioned; 234 patients (70 per cent) were initially managed conservatively. Appropriate local care and nutrition were provided in all cases. Enteral nutrition was the exclusive nutritional support in 285 patients (85 per cent). In 92 cases with proximal fistulae, methods limiting the fistula output or allowing reinfusion of chyme were required. The overall mortality rate was 34 per cent: 100 per cent in the non-intervention group, 55 per cent after emergency surgery, and 19 per cent after conservative treatment. In the latter group, spontaneous closure was obtained in 88 patients (38 per cent). Overall mortality rate was reduced to 19 per cent in patients treated since 1980. Enteral nutrition with appropriate local care may be used in the majority of high-output enterocutaneous fistulae, with an acceptable rate of spontaneous closure. Conservative management is the treatment of choice in the initial period. Emergency surgery should be restricted to the treatment of haemorrhage or intra-abdominal abscesses associated with uncontrolled systemic sepsis.

Epidermoid carcinoma of the anal canal treatment results and prognostic variables in a series of 242 cases.

UNLABELLED: From 1972 to 1985, 260 cases of anal canal epidermoid carcinoma were irradiated. Eighteen cases treated for palliation were excluded from the study; 242 (93%) were treated with curative intent. The sex ratio was 1/5.5; mean age was 66 years. HISTOLOGY: 60.3% were well differentiated epidermoid carcinoma; 31.0% moderately differentiated and 8.7%, cloacogenic cases. Staging: T1: 11.5%; T2: 16.1%; T3a: 17%; T3b: 33.5%; and T4: 21.9%. Abnormal inguinal nodes were present in 15.3% of cases. Crude overall survival (Kaplan-Meier) for the 242 cases is 86.4% at 1 year, 63.9% at 3 years, 51.2% at 5 years, and 30.8% at 10 years. Radiation therapy was the sole treatment for 193 cases. No chemotherapy was given. Patients were irradiated by external beam. They received a first course of X rays (mostly 18 MV, some 6 MV) 40 to 45 Gy (box technique) over 4 to 5 weeks in the pelvis. Age and size of tumor were considered when deciding on the target volume. After a rest period of 4 to 6 weeks, a second course of 15 to 20 Gy in 2 weeks was given through a perineal field by electron-beam of suitable energy. The mean total dose was 60.56 Gy and median was 62.5 Gy; the mean overall treatment duration was 85.3 days (median 82 days) and the mean Time Dose Factor including decay factor was 98.96. In this group, 5-year determinate survival was: T1-T2, 84.5%; T3a, 74.8%; T3b, 64.9%; T4, 58.9%. In 147/193 patients (76.2%) local control was achieved. The overall anal conservation rate was 62.6%. In 106 cases (55%), the anus had maintained normal function. The 5-year survival rate by N was 73.3% in the absence of inguinal nodes (169 cases) and 36.1% if such nodes were present. There was no significant difference in survival rate according to histological type. In the second group, receiving radiation therapy plus surgery, 33/49 cases (T3b-T4) were irradiated before surgery (median dose 40.5 Gy). Post operative radiation therapy was administered in 16 cases (T3b-T4) (median dose 49.6 Gy). The 5-year determinate survival is 53.2% for T3b and 79% for T4. According to the log-rank test, there was no significant difference between survival with radiation therapy alone and radiation therapy plus surgery. Multivariate analysis of the whole group indicated that T stage is the only predictive variable.(ABSTRACT TRUNCATED AT 400 WORDS)

Vascular occlusions for liver resections. Operative management and tolerance to hepatic ischemia: 142 cases.

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.

Pharmacological effect of somatostatin on bile secretion in man.

Somatostatin (SST) has been shown to induce cholestasis in the dog and in the rat. In man, it is still unknown whether SST modifies bile formation. The present study was undertaken to examine the influence of SST on bile secretion in man. Two volunteers who had a total external biliary fistula received 1-hour SST infusions (3.5 micrograms/kg/h). Bile flow, bile acid, phospholipid and cholesterol biliary outputs were measured before, during and 1 h after the infusion. The SST infusion was associated with a pronounced decrease in bile flow and in bile acid secretion and with an increase in bile cholesterol saturation. These findings suggest that SST has cholestatic properties in man as in other species. This may provide a rational explanation for the formation of gallstones and for the steatorrhea observed in patients with somatostatinomas or during therapeutic SST administration.

[Must we reject primary colostomy in left colonic obstruction caused by cancer?].

Treatment of left colonic cancer obstruction is not still clear. Many procedures can be done, simple decompressive colostomy by a local incisionnal way to subtotal colectomy with primary anastomosis. What can we do today? Retrospective study from 1983 to 1988 at Centre de Chirurgie Digestive de l'Hôpital Saint-Antoine (Paris) with 36 datas was done. The emergency treatment was 20 decompressive colostomies, 10 primary resections without anastomosis, 2 subtotal colectomies with ileo-sigmoid primary anastomosis, 2 left colectomies with primary anastomosis (2 with decompressive colostomy, one without) and one Hartmann procedure. One patient is dead after decompressive colostomy. After emergency decompressive colostomy, 16 patients (80%) were reoperated for colonic cancer resection, with suppression of the stomy fifteen times. There were 7 extra abdominal complications and 3 stomy complications (2 incisionnal hernias after closure of the stomy and one prolapse of a definitive colostomy). After emergency primary resection without anastomosis, 9 patients (90%) were reoperated for secondary anastomosis. Morbidity was 3 extra abdominal complications. The mean hospital stay was 28 days for these 2 groups. For all the patients with primary or secondary anastomosis there was no anastomotic leak. Decompressive colostomy as emergency procedure for left obstructing carcinoma is simple, efficiency and safe. It can be associated with low mortality and morbidity. To day, we still recommend this procedure.

[Acute necroticohemorrhagic pancreatitis. Why, when and how to drain? Apropos of 106 cases].

The heavy toll of necrotizing acute pancreatitis led the authors to start developing a new method of treatment in experimental and clinical conditions in 1979. This was aimed on one hand at creating a large channel for the centrifugal drainage of pancreatic or peri-pancreatic foci, and on the other hand at maintaining this draining channel during the first 5 weeks of acute evolution of the acute necrotizing pancreatitis in order to allow the permanent evacuation of purulent or necrotic fragments. From 1979 to 1989, 106 patients were treated with this method, ie. 71 men and 35 women with an average age of 47.9 years. 73 (74%) of these patients had been referred by other hospitals, and 64 only had been initially operated at Saint-Antoine hospital. All patients presented with extensive peripancreatic necrosis. The average Ranson score was 4.8 (not taking the fluid sequestration during the first few hours into account). Visceral failure was observed in 76% of the patients before surgery. The necrosis of the pancreatic gland was focal in 6 cases, extensive in 47 cases and total or subtotal in 25 cases. Out of the 70 CT studies, 64 showed a Ranson grade of E. All patients received enteral feeding on a jejunal site postoperatively. The mortality rate was 16%. The stay of the surviving patients in the intensive care unit averaged 50 days. 29 patients (27%) were reoperated on for complications or insufficient drainage.

Comparative clinical results of ileal-pouch anal anastomosis and ileorectal anastomosis in ulcerative colitis.

The aim of the study was to compare the results of ileal-pouch anal anastomosis (IAA) and total abdominal colectomy with ileorectal anastomosis (IRA) in the treatment of ulcerative colitis. The number of patients included in the comparative trial was 104 (IAA) and 197 (IRA), respectively. No clear advantage of IRA over IAA was seen: postoperative mortality and morbidity were about the same; functional results as shown by the frequency of stools and daytime continence were virtually equal. A factor favoring IAA was, among others, recurrence of proctitis after IRA which is more difficult to treat than the pouchitis occurring after IAA and is associated with a higher rate of secondary permanent end ileostomy; besides, IRA entails the risk of cancer developing in the rectal stump, while at the same time it is difficult to follow up these patients closely enough. IRA is indicated only if the diagnosis of ulcerative colitis is in doubt; if the patient is more than 60 years of age; and if IAA proves technically too difficult, IAA is usually preferable, however, if there is any doubt as to whether the patient is suffering from ulcerative colitis or Crohn's disease, ileorectostomy is preferred which does not preclude IAA at a later date in case of need.

[Ileo-anal anastomosis: various types of ileal reservoir].

The creation of an ileal reservoir ensures an improvement in the functional result obtained after ileo-anal anastomosis. As a result of its storage function, the reservoir allows a reduction in the number of stools per day. Several types of reservoir have been described. The S-shaped reservoir consists of three aniso-peristaltic limbs and an efferent loop with end-to-end ileo-anal anastomosis. The W reservoir is equivalent to a double J reservoir. The side-to-side iso-peristaltic reservoir consists of two iso-peristaltic limbs and an efferent loop with end-to-end ileo-anal anastomosis. After analysing the specific characteristics of each type of reservoir, the authors conclude that the necessity of a reservoir no longer needs to be demonstrated, but that there is no formal argument in favour of one particular model.

Continuous enteral nutrition during the early adaptive stage of the short bowel syndrome.

Sixty-two patients with the short bowel syndrome (30-150 cm) were managed by continuous enteral nutrition (CEN) in the early adaptive phase. In all, 82 per cent were referrals from other units and 85 per cent of referrals had failure of one or more organ systems on admission. There were intra-abdominal abscesses in 41 per cent of patients and 37 per cent had an enterocutaneous fistula. The diet included polysaccharides, medium chain triglycerides and protein hydrolysates, mixed with a high-viscosity tapioca suspension. An elemental diet was used initially in 15 per cent of patients. Thirty-three patients had an interruption of the gastrointestinal tract by a temporary enterostomy. Chyme was re-infused into the distal intestine in 20 cases. 'Zero-time' was taken as the time of operation or, for referred patients treated conservatively, the date of admission. CEN was commenced at a mean of 14 days from zero-time. Total parenteral nutrition could be discontinued at a mean of 36 days and exclusive oral alimentation was resumed at a mean of 87 days. Patients with small bowel longer than 80 cm attained enteral autonomy earlier than patients with a shorter length. Mean faecal volume did not increase following institution of CEN, suggesting tolerance to the high-viscosity diet. In cases with re-infusion of enteric content, the distal circuit (length of distal small intestine 46 cm) was able to absorb 70 per cent of the volume re-infused (mean volume 2700 ml). Body weight and nutritional markers increased significantly during the course of CEN. This study suggests that enteral autonomy can be attained early in the short bowel syndrome, even under challenging conditions. Elemental formulae do not appear to offer a benefit over polymeric diets.

Single-layer anastomosis in surgery of the large bowel. A prospective study on 316 cases in a university hospital.

A prospective study was undertaken to evaluate the results of a single layer appositional technique for large bowel anastomoses used in a University Hospital. 316 patients were entered during an 18-month period. Anastomoses were situated within the peritoneal cavity in 277 patients and below the peritoneal reflection in 39. No covering stoma was made. The incidence of clinical leakage was 1.6% and of wound infection 1.9%. These results compare favourably with those obtained by stapling. For intraperitoneal anastomoses and high anterior resection manual suture remains the standard technique and is less expensive than stapling. For low rectal tumours, there is still debate on the relative merits of stapling and various manual techniques of colo-anal anastomosis in terms of morbidity, tumour clearance and functional results.

Septic necrosis of the midline wound in postoperative peritonitis. Successful management by debridement, myocutaneous advancement, and primary skin closure.

Wound management following laparotomy for postoperative peritonitis and varying degrees of parietal necrosis remains a challenging and controversial problem. Because maintained peritoneal integrity and primary wound closure offer the best opportunity for survival, an original technique involving bilateral incisions to relax skin and rectus fascia is proposed. This technique permits medial myocutaneous advancement and primary tension-free skin closure of midline laparotomy incisions. Sixty-nine patients with severe postoperative peritonitis were treated according from 1980 through 1985. Nine of these patients died of advanced multiple organ failure soon after referral, and eight more died after prolonged treatment. Fourteen patients had one or more reoperations for complications. Only nine wound failures resulted, including five eviscerations and four wound infections followed by progressive dehiscence. The bilateral relaxing incisions healed secondarily without complication. Survivors developed midline wound hernia; ten of the 52 surviving patients have had these repaired. This method of primary closure is safe when performed in conjunction with rigorous surgical care of intraperitoneal infection and may enhance survival. We recommend the technique to surgeons who treat severe postoperative peritonitis and septic necrosis of midline laparotomy wounds.
