Laparoscopic pylorus-preserving pancreatoduodenectomy.

A case of chronic pancreatitis localized in the head of the pancreas with pancreas divisum was treated by laparoscopic pylorus-preserving pancreatoduodenectomy. The laparoscopic technique of resection and reconstruction with a gastrojejunostomy, hepaticojejunostomy, and pancreaticojejunostomy is described. The postoperative period was complicated by a jejunal ulcer and delayed gastric emptying necessitating a prolonged hospitalization and intravenous hyperalimentation. No fistulas occurred, a follow-up CT scan revealed no pancreatic abnormalities, and the patient was discharged in good condition on the 30th postoperative day. Although technically feasible, the laparoscopic Whipple procedure may not improve the postoperative outcome or shorten the postoperative recovery period.

Malignant biliary obstruction: preliminary results of palliative treatment with hepaticogastrostomy under fluoroscopic, endoscopic, and laparoscopic guidance.

PURPOSE: To report a technique of peripheral biliary decompression by means of anastomosis of a bile duct in segment II of the liver to the lesser curvature of the stomach. MATERIALS AND METHODS: Seven patients with unresectable biliary neoplasm were treated. After transhepatic catheterization of a segment II bile duct, the left lobe of the liver and the lesser curvature of the stomach were perforated under fluoroscopic and laparoscopic guidance. Anastomosis between the biliary tree and the stomach was maintained with a gastrostomy tube placed across the tract. After 2 weeks, the tube was removed and patency of the tract was preserved with a metallic stent. RESULTS: Three patients died, at 3, 6, and 9 months, respectively, without reocclusion; the other four were alive at 5 months without jaundice. One patient had an episode of cholangitis, which was resolved with antibiotic therapy. CONCLUSION: This method yields a good patency rate with few problems. Further investigation is required to evaluate long-term patency and the necessity of laparoscopic guidance.

Routine operative cholangiography during laparoscopic cholecystectomy: feasibility and value in 107 patients.

OBJECTIVE: Laparoscopic cholecystectomy is becoming a popular alternative to open cholecystectomy. However, the technical aspects of this new procedure increase the risk of injuring the bile ducts. The purpose of this study was to determine the feasibility and value of performing cholangiography during laparoscopic cholecystectomy. MATERIALS AND METHODS: We retrospectively reviewed the clinical and operative cholangiographic findings of the first 107 patients undergoing laparoscopic cholecystectomy at Hôtel-Dieu de Montréal between August 1990 and August 1991. RESULTS: Operative cholangiography was attempted in 98% of patients; the success rate was 71%. Eight anatomic anomalies of the biliary tract that were of surgical importance were found as well as 10 cases of stones in the common bile duct, eight of which were unsuspected. No biliary tract injuries occurred. With experience, surgical cannulation of the cystic duct for injection of contrast material can be done quickly without major difficulty, and cholangiograms of excellent diagnostic quality can be obtained. CONCLUSION: Our results show that operative cholangiography is feasible and useful in patients undergoing laparoscopic cholecystectomy.

Early experience with laparoscopic approach for adrenalectomy.

BACKGROUND: Adrenalectomy performed by a posterior or transabdominal approach causes substantial postoperative pain. The purpose of this study was to evaluate laparoscopy as a potential approach for adrenalectomy. METHODS: We performed 25 consecutive laparoscopic adrenalectomies on 22 patients from April 1, 1992, to March 30, 1993. Laparoscopic surgery was performed by using a lateral decubitus flank approach with four 11 mm trocars. RESULTS: Twelve right and 13 left adrenal glands were removed in a mean time of 2.3 hours. Three patients underwent bilateral adrenalectomies in a mean time of 5.3 hours. The 15 women and 7 men range in age from 31 to 60 years (mean, 42 years). The adrenal gland diseases were nonfunctional adenoma (seven), pheochromocytoma (five), Cushing's disease (four), Cushing's adenoma (four), primary aldosteronism (two), dehydroepiandrostenedione sulfate hypersecretion (one), angiomyolipoma (one), and medullary cyst (one). Average tumor size was 4.1 cm (range, 1 to 15 cm). Laparoscopic adrenalectomy was successful in 96% of patients, with one patient requiring a laparotomy because of inadequate exposure. The median postoperative stay was 4 days (range, 2 to 19), with a mean of five narcotic injections. There were no deaths, and morbidity was minor. CONCLUSIONS: Laparoscopy can be used successfully for adrenalectomy. It produces less postoperative pain and rapid return to normal activity. It may be the preferred method for removing most adrenal gland lesions that require operation.

Dietary habits after ileal pouch-anal anastomosis.

Dietary habits of patients who had undergone ileal pouch-anal anastomosis were assessed and correlated with bowel function. Twenty-four well-adapted patients (11 women, 13 men; mean age 32 years) voluntarily entered the study 30 +/- 4 months after closure of the diverting ileostomy. A standardized questionnaire on 108 food items and a 3-day food journal were used in the assessment. Twenty-one patients had no difficulty in selecting an appropriate diet. Caloric intake was adequate. Specific symptoms associated with several foods were as follows: increased stool frequency (beer, spirits, chinese food), decreased stool consistency (beer, wine, fried fish), perianal irritation (spicy foods), undigested particles (grapefruit, lettuce), odours (eggs). Pasta and bananas were associated with increased stool consistency. The authors believe that these observations may help in dietary counselling after ileal pouch-anal anastomosis.

Use of retinol-binding protein and prealbumin as indicators of the response to nutrition therapy.

There is no single available measurement for evaluating the short-term response to nutrition therapy. The ideal parameter should have high sensitivity and specificity and should be unaffected by non-nutritional factors. A literature review suggested that plasma retinol-binding protein and prealbumin concentrations change earlier than albumin and transferrin levels and appear to correlate better with nitrogen balance during nutrition therapy. That conclusion was supported by our own findings in patients receiving total parenteral nutrition and following the transition to oral or enteral feedings. Although concentrations of these plasma proteins have been shown to be affected by stress and renal and hepatic disease, they appear to be more sensitive indicators of the adequacy of nutrition support than other more commonly used assessment parameters.

Subcutaneous infusion ports for administration of parenteral nutrition at home.

We evaluated 15 adult patients in whom subcutaneous infusion ports (SIP) were implanted exclusively for the administration of parenteral nutrition at home (HPN). The SIP were in place for a total of 4,939 days, with a mean of 259 days, and used for delivery of HPN 2,534 times. The devices were implanted on the anterior part of the wall of the chest and the catheters introduced percutaneously through the subclavian vein into the superior vena cava under fluoroscopic guidance. There were two episodes of sepsis related to insertion of catheters (1.0 per 6.8 catheter years) and six mechanical complications. Three patients with multiple previous episodes of sepsis associated with Hickman catheters (long term Silastic [silicone rubber] central venous catheter) had no further infections after conversion to SIP. All eight patients with previous Hickman catheters preferred the SIP. The SIP compare favorably with Hickman catheters with respect to the incidence of sepsis related to the catheters and mechanical complications. SIP are our current choice for cyclic administration of HPN because of optimal acceptance by patients and a low rate of major complications.

Demonstration of a bronchobiliary fistula by 99mTc-HIDA cholescintigraphy.

A case of bronchobiliary fistula diagnosed by 99mTc-HIDA cholescintigraphy is presented. The fistula caused by a stenosing tumor of the left hepatic duct would probably have been missed without the use of delayed views and body fluids counting which increased the specificity of scintigraphic findings.

Laparoscopic pancreatic resection: Is it worthwhile?

A series of 23 patients who had undergone an attempted laparoscopic Whipple (n = 10) or laparoscopic distal pancreatectomy (n = 9) or laparoscopic enucleation (n = 4) since January 1992 were retrospectively reviewed. In the laparoscopic Whipple group (6 women and 4 men; mean age 71 [range 33 to 82] years), eight had malignant periampullary tumors and two had chronic pancreatitis. The rate of conversion to an open procedure was 40%, and complications were seen in the nonconverted group. The average operative time was 8.5 hours, and the hospital stay was 22.3 days. However, in the laparoscopic distal pancreatectomy and enucleation groups, there were seven women and six men (mean age 46.5 [range 27 to 75] years). Of these, nine patients had a planned laparoscopic distal pancreatectomy (8 for islet cell tumors and 1 for chronic pancreatitis) and four had a planned laparoscopic enucleation (all 4 for islet cell tumors). The conversion rate for these patients was 36%, and the mean operative time was 4.5 hours for laparoscopic distal pancreatectomy and 3 hours for laparoscopic enucleation. The hospital stay was 5 days and 4 days, respectively. Although this series was small, no benefit seemed to be derived from the use of a complete laparoscopic Whipple procedure. Laparoscopic distal pancreatectomy and enucleation were technically easier to perform and seemed to benefit patients by shortening their hospital stay with no recurrence of disease.
