Early conversion for gangrenous cholecystitis: impact on outcome.

BACKGROUND: Early conversion from laparoscopic to open cholecystectomy for patients with gangrenous cholecystitis has been advocated. This study investigated the impact of early conversion on patient outcome. METHODS: Data from all patients with gangrenous cholecystitis undergoing laparoscopic cholecystectomy between 1992 and 2002 whose procedure had been converted to open surgery were prospectively collected and analyzed. Morbidity, length of stay, intensive care unit admission, and operative time served as outcome measures. RESULTS: Of the 97 patients in the study, 33 underwent conversion to open cholecystectomy. The conversion was early for 24% of the patients, after the initial dissection, for 33% and after an extended attempt at completion of the laparoscopic cholecystectomy for 37%. There was no difference in the overall morbidity among the groups, whereas the length of hospital stay appeared to be longer in the early conversion group. The operative time was significantly shorter after early conversion (p < 0.01, chi-square test). CONCLUSION: Laparoscopic cholecystectomy is not feasible for all patients with gangrenous cholecystitis. However, a concerted effort to perform the cholecystectomy with the minimally invasive approach does not have an adverse impact on patient outcome and is likely to benefit patients although it poses a moderate risk of conversion.

Open Rives-Stoppa ventral hernia repair made simple and successful but not for everyone.

BACKGROUND: The Rives-Stoppa (RS) repair of ventral incisional hernias (VIHR) is technically difficult. It involves the retromuscular placement of mesh anterior to the posterior fascia and the primary closure of the anterior fascia. Recurrence rates are 0-8%. We proposed that the operation could be done with equal success by placing the mesh in an intraperitoneal position and primarily closing the fascia anterior to the mesh. METHODS: 81 patients who had undergone an open RS-VIHR with intraperitoneal mesh were evaluated for hernia recurrence and factors associated with recurrence. RESULTS: 55 women and 26 men (mean BMI 38+/-9) underwent RS-VIHR (mean age 49+/-11 years). Of these patients, 44 (54%) had a prior VIHR, 30 (37%) had an incarcerated hernia and 34 (42%) had multiple fascial defects. PTFE was used in 83% and Prolene in 12%. Average LOS was 5.8+/-12 days. All received perioperative intravenous antibiotics and 28% were discharged on oral antibiotics. Follow-up averaged 30+/-24 months. Recurrent VIH developed in 12/81 (15%), with three occurring after removal of infected mesh and one after a laparotomy. Excluding these four, the recurrence rate was 10%. There was no correlation between hernia recurrence and age, BMI, hernia size, number of prior repairs, or LOS (t-test p>0.05). Hernia recurrence did not correlate with gender, prior peritoneal contamination, incarceration, multiple defects, adhesions, mesh type, oral antibiotics, cardiac disease, diabetes, tobacco use, or seroma (X(2) p>0.05). Those with a wound infection and/or abscess formation had a significantly higher recurrent hernia rate (60% vs. 8%, X(2) p<0.001). Patients with pulmonary disease had a significantly higher recurrence rate (50% vs. 12%, X(2) p=0.01). CONCLUSIONS: RS-VIHR with intraperitoneal mesh is a successful and less technically challenging method of repair than prior modifications. Aggressive efforts to identify infection and treat early may prevent abscess formation and subsequent recurrent hernia. Patients with chronic pulmonary disease have an unacceptably high recurrence rate and should not be considered as candidates for elective RS-VIHR.

Laparoscopic cholecystectomy for biliary dyskinesia: correlation of preoperative cholecystokinin cholescintigraphy results with postoperative outcome.

BACKGROUND: A gallbladder ejection fraction (EF) on cholescintigraphy of less than 35% after cholecystokinin (CCK) has been considered to be pathophysiologic and an indication for laparoscopic cholecystectomy (LC). METHODS: All patients undergoing LC for biliary dyskinesia between 1994 and 2001 were prospectively entered into a database. These patients were retrospectively evaluated with regard to demographics, the number of preoperative studies obtained, postoperative symptoms, and the number of postoperative studies obtained. RESULTS: Sixty patients underwent LC for biliary dyskinesia. The mean gallbladder EF was 14%, and 75% of patients were asymptomatic postoperatively. Persistent symptoms prompted further investigation in 6% of patients with a gallbladder EF <14% and in 35% of patients with an EF between 14 and 35% (p = 0.05). CONCLUSION: Laparoscopic cholecystectomy alleviated symptoms in 94% of patients with a gallbladder EF <14% after CCK injection. The diagnostic significance of a preoperative CCK cholescintigram (EF 14-35%) needs further investigation.

Bidirectional endoscopy in patients with fecal occult blood.

BACKGROUND: Current screening protocols for colorectal cancer depend primarily on fecal occult blood testing (FOBT). However, positive test results do not always indicate the presence of a colonic neoplasm. METHODS: We reviewed the results of 100 consecutive bidirectional (upper and lower) endoscopic procedures performed to evaluate positive FOBT results. Patients were excluded if they presented with gross bleeding, a history of bowel lesions, or previous intestinal operations. There were 31 women and 69 men whose mean age was 51 years. RESULTS: Major abnormalities were found on esophagogastroduodenoscopy (n = 24), colonoscopy (n = 13), or both studies (n = 2). Active bleeding was manifested in two patients, (Barrett's ulcer, duodenal arteriovenous malformation). Two other patients had malignancy: One had a cecal adenocarcinoma and the other a gastric adenocarcinoma. Various benign lesions also were identified in the stomach including esophagitis (n = 8), ulcers/erosions (n = 8) varices (n = 5), and arteriovenous malformations (n = 2). Colonic pathology included polyps (n = 8), arteriovenous malformations (n = 3), and rectal varices (n = 1). Diverticulosis and hemorrhoidal disease were present in 29 and 16 patients, respectively, but were not considered to be likely sources of a positive FOBT. CONCLUSION: Positive FOBT results may indicate the presence of either upper or lower intestinal pathology, and bidirectional endoscopy is an efficient and accurate technique for the comprehensive evaluation of occult bleeding.

Jejunoileal causes of overt gastrointestinal bleeding: diagnosis, management, and outcome.

Major bleeding from the small intestine is uncommon and difficult to localize. We examined its etiologies and assessed available diagnostic and therapeutic approaches. The records of all adults undergoing operation for small intestinal hemorrhage over a 10-year period (1/89-12/98) were reviewed. There were eight men and four women with a mean age of 54 years. Six patients presented with arteriovenous malformations. Preoperative diagnosis was by endoscopy (three of six), scintigraphy (two of two), and/or angiography (two of six). Intraoperative panendoscopy was used for localization in 5 cases. Three other patients had tumors (leiomyoma, leiomyosarcoma, and adenocarcinoma) by CT scan (two) and/or scintigraphy (two). All were resected but one patient died of recurrence. Two patients underwent resection of a Meckel's diverticulum, one after angiographic diagnosis. Another patient with Crohn's disease had a positive angiogram and colonoscopy before resection. There were no operative deaths but major morbidity occurred in five patients (42%) and hospitalization averaged 17 days. We conclude that jejunoileal lesions are a rare cause of intestinal bleeding but can be associated with substantial morbidity. Arteriovenous malformations and tumors remain the most common causes. An accurate diagnosis and definitive management depend on selective preoperative imaging and judicious operative exploration.

Treatment of acute cholecystitis in non-critically ill patients at high surgical risk: comparison of clinical outcomes after gallbladder aspiration and after percutaneous cholecystostomy.

OBJECTIVE: This study was performed to compare the clinical outcome after gallbladder aspiration with that after percutaneous cholecystostomy in non-critically ill patients with acute cholecystitis who were at high risk from surgery. MATERIALS AND METHODS: Medical records of 53 consecutive non-critically ill, high-surgical-risk patients admitted with acute cholecystitis between July 1995 and July 1999 were reviewed. Thirty-one had gallbladder aspiration and 22 had percutaneous cholecystostomy. The primary outcome measure of clinical response within 72 hr and the secondary outcome measures of overall positive response rate, complication rate, time to resolution, and rate of recurrence of acute cholecystitis were compared between the two groups. RESULTS: Gallbladder aspiration and percutaneous cholecystostomy were technically successful in 30 (97%) and 21 (97%) patients, respectively; of these, 23 (77%) and 19 (90%) patients responded clinically within 72 hr (p > 0.2). Complications occurred in three patients (12%) after percutaneous cholecystostomy and in none after gallbladder aspiration (p < 0.05). No significant difference was noted in the other secondary outcome measures of the two groups. CONCLUSION: We found no significant difference in the clinical outcomes of gallbladder aspiration and percutaneous cholecystostomy in the treatment of acute cholecystitis in high-surgical-risk patients who are not critically ill. However, we found gallbladder aspiration to be significantly safer. Therefore, gallbladder aspiration should be the procedure of choice in high-risk patients with acute cholecystitis who are not critically ill, and percutaneous cholecystectomy should be reserved as a salvage procedure if gallbladder aspiration is technically or clinically unsuccessful.

Operations for peptic ulcer disease: paradigm lost.

Over the past several decades, the pharmacologic and endoscopic treatment of peptic ulcer disease (PUD) has dramatically improved. To determine the effects of these and other changes on the operative management of PUD, we reviewed our surgical experience with gastroduodenal ulcers over the past 20 years. A computerized surgical database was used to analyze the frequencies of all operations for PUD performed in two training hospitals during four consecutive 5-year intervals beginning in 1980. Operative rates for both intractable and complicated PUD were compared with those for other general surgical procedures and operations for gastric malignancy. In the first 5-year period (1980 to 1984), a yearly average of 70 upper gastrointestinal operations were performed. This experience included 36 operations for intractability, 15 for hemorrhage, 12 for perforation, and seven for obstruction. During the same time span, 13 resections were performed annually for gastric malignancy. By the most recent 5-year interval (1994 to 1999), the total number of upper gastrointestinal operations had declined by 80% (14 cases), although the number of operations for gastric cancer had changed only slightly. Operations decreased most markedly for patients with intractability, but the prevalence of operations for bleeding, obstruction, and perforation was also decreased. We conclude that improved pharmacologic and endoscopic approaches have progressively curtailed the use of operative therapy for PUD. Elective surgery is now rarely indicated, and emergency operations are much less common. This changed paradigm poses new challenges for training and suggests different approaches for practice.

Operative management of diverticular emergencies: strategies and outcomes.

HYPOTHESIS: A selective surgical approach using either a 1- or a 2-stage resection is relatively safe and effective in the management of acute complicated colonic diverticulosis. DESIGN: A consecutive cohort study. SETTING: A university hospital. PATIENTS: Eighty-nine consecutive patients who underwent emergency operations for diverticular disease between July 1, 1984, and June 30, 1999. There were 53 male and 36 female patients (mean age, 47 years). The ethnic background was predominantly Mexican American (58 patients [65.2%]). INTERVENTIONS: Resections of the affected colon (n = 83) plus construction of a Hartmann pouch or mucous fistula (n = 72) or primary anastomosis (n = 11). MAIN OUTCOME MEASURES: Morbidity, mortality, and length of hospital stay. RESULTS: Sixty-eight operations were performed for perforation at an annual rate that has increased greater than 75% in the past 15 years. Another 14 patients underwent operations for obstruction, and 7 underwent operations to control unremitting hemorrhage. Surgical therapy included resection of the affected segment of the bowel in 83 (93%) of the 89 patients, and a Hartmann pouch or mucous fistula was added in 72 (81%). A primary anastomosis was performed in 4 (80%) of 5 right-sided lesions but in only 7 (8%) of 84 left-sided lesions. Morbidity occurred in 38 (43%) of the 89 patients, and the mortality was 4%, with 4 deaths occurring secondary to sepsis in high-risk patients with perforations (n = 3) or obstructions (n = 1). The average length of hospital stay was 19.7 days (range, 5-80 days). CONCLUSIONS: Emergency operations for diverticular disease are uncommon but may be associated with substantial morbidity and occasional mortality. Complicated diverticulosis may present at a relatively young age, and perforated forms appear to be increasing rapidly in prevalence. Most diverticular lesions can be satisfactorily managed using a selective approach based on resection with either a primary anastomosis or a temporary colostomy.

Laparoscopic cholecystectomy and cirrhosis: a case-control study of outcomes.

The incidence of gallstone disease in patients with cirrhosis is greater than that in healthy patients. Previous surgical literature reported greater morbidity and mortality in patients with cirrhosis with both open and laparoscopic cholecystectomy (LC). We compared our recent experience with LC in patients with cirrhosis and controls. A retrospective review was performed using the search terms, "cirrhosis" and "laparoscopic cholecystectomy." Forty-eight patients with cirrhosis were identified and randomly matched with healthy controls by age and sex. Four controls were assigned per patient with cirrhosis. Outcomes assessed included mortality, duration of surgery, length of hospital stay, blood transfusion requirement, postoperative complications, and need for conversion to open cholecystectomy. Forty-eight patients with cirrhosis and 187 healthy controls underwent LC. Child-Pugh classification of severity of liver disease was as follows: Child's class A, 38 of 48 patients; Child's class B, 10 of 48 patients; and Child's class C, 0 of 48 patients. Patients with cirrhosis had statistically significantly lower albumin levels (P =.0001) and prolonged prothrombin times (P =. 05). Average duration of surgery for patients with cirrhosis was 1. 71 versus 1.57 hours (P =.57) for controls. Average length of hospital stay for patients with cirrhosis was 6.47 versus 4.77 days (P =.152) for controls. Average number of units of blood transfused in patients with cirrhosis was 0.156 versus 0.0 units (P =.025) in controls. Complications occurred in 6 of 48 patients with cirrhosis (12.5%) and 8 of 187 controls (4.2%; P <.05). No child's class C patient underwent LC. Four patients with cirrhosis (8.3%) and no controls were converted to open cholecystectomy. No postoperative infections were noted. There was no mortality in either group. LC in patients with Child's class A and B cirrhosis is reasonably safe and shows no increase in morbidity or mortality or worsening of outcome. Further studies are required to evaluate the management of acute gallbladder disease in Child's class C patients.

Diagnosis and treatment of intra-abdominal abscesses.

Despite recent advances in the diagnosis and management of intra-abdominal abscesses, these infections still cause substantial morbidity and mortality. Low pH, large bacterial inocula, poor perfusion, the presence of hemoglobin, and large amounts of fibrin (which impedes antibiotic penetration) make the abscess a cloistered environment that is penetrated poorly by many antimicrobial therapies. Therefore, management of these infections requires prompt recognition, early localization, and effective drainage, as well as appropriate antimicrobial use. Although various imaging techniques, such as ultrasonography, gallium scans, and indium-labeled white-blood-cell scans, can be used for the diagnosis and localization of intra-abdominal abscesses, computer-assisted tomography is the most useful study. Once the diagnosis is made and the abscess is localized, treatment should begin promptly. Percutaneous or open surgical drainage should be used. Broad-spectrum antibiotics should be given until culture and sensitivity data are obtained. Once these data are obtained, a therapy with appropriate coverage that is likely to work in the abscess environment should be chosen. Percutaneous drainage is inappropriate for abscesses in the posterior subphrenic space or in the porta hepatis, for those among loops of small bowel, for suspected echinococcal cysts, and for abscesses containing necrotic or neoplastic tissues. Finally, surgeons need to be cognizant of risk factors, such as advanced age, obesity, complex abscesses, and high Acute Physiology and Chronic Health Evaluation (APACHE) II or APACHE III scores, which correlate with poor outcomes for these patients.

Laparoscopic cholecystectomy for biliary tract emergencies: state of the art.

Although laparoscopic cholecystectomy is unusually safe and well tolerated in patients with routine symptomatic cholelithiasis, it can become a formidable procedure when used to manage biliary tract emergencies. Optimally, a reasoned and cautious approach and a low threshold for conversion can avoid major complications. One such emergency, acute cholecystitis, may be particularly hazardous because of the relatively common finding of severe inflammation with dense adhesions to adjacent viscera and gallbladder necrosis. Special modifications of technique may be required. Overall, urgent operation (within 72 hours) results in an acceptably low mortality (0.3%) but a somewhat higher conversion rate (16%) and longer hospital stay (3 days). Unnecessary delays may result in more adhesions and an increased level of operative difficulty. In patients who are at an especially high risk because of co-morbid disease, percutaneous cholecystostomy is an appropriate alternative strategy. Biliary pancreatitis may be associated with high mortality (9%) and has an unpredictable course. Accordingly, a multidisciplinary approach that may include both gastroenterologists and radiologists is generally advisable. Because common bile duct (CBD) stones are present in more than 20% of patients who present with biliary pancreatitis, endoscopic retrograde cholangiopancreatography (ERCP) can be used effectively on a selective basis during the preoperative or postoperative period; the preferred timing continues to be somewhat controversial. As an alternative approach, laparoscopic CBD exploration is gradually gaining wider acceptance. In eight reported series using a variety of techniques for stone extraction, major complications were infrequent (10%), and the conversion rate was low (5%). Acute suppurative cholangitis is a more fulminant problem that is best managed by expeditious ERCP with removal of all intraductal stones. Resuscitation should be continued until complete; laparoscopic cholecystectomy can follow at an appropriate interval.

Biliary pancreatitis: the era of laparoscopic cholecystectomy.

OBJECTIVE: To evaluate the efficacy and safety of a combined approach to the treatment of biliary pancreatitis using laparoscopic cholecystectomy and selective endoscopic retrograde cholangiopancreatography (ERCP). DESIGN: Consecutive case series. SETTING: Tertiary care center. PATIENTS: All patients undergoing primary operations for biliary pancreatitis during 2 time periods were included. In the open era (June 1982 through May 1988), there were 276 patients; in the laparoscopic era (January 1996 through June 1997), there were 114 patients. INTERVENTIONS: Open cholecystectomy with or without common bile duct exploration (CBDE); laparoscopic cholecystectomy with selective ERCP and/or laparoscopic CBDE. MAIN OUTCOME MEASURES: Two periods were compared for morbidity, mortality, the duration of preoperative and postoperative stays, and the total length of hospitalization. RESULTS: Both groups were demographically similar and had the same mortality (1.9%). Laparoscopic cholecystectomies provided a preoperative stay comparable to open cholecystectomy (6.4 vs 5.8 days), a shorter postoperative stay (1.5 vs 8.5 days), a lower incidence of CBDE (6.6% vs 26%), and a lower morbidity (8% vs 13.7%). The addition of an ERCP to laparoscopic cholecystectomy was associated with prolongation of the preoperative stay (7.4 vs 5.0 days), a comparable postoperative stay, a lower conversion rate (7.5% vs 13%), and fewer CBDEs (3% vs 13%). In 27 (42%) of the 64 ERCP cases, no stones were found. CONCLUSIONS: Treatment of biliary pancreatitis with combined laparoscopic cholecystectomy and selective ERCP is safe and effective and is associated with a shorter hospitalization and fewer CBDEs than open cholecystectomy. Unnecessary ERCPs can be reduced by improved selection criteria or greater dependence on operative CBDE.

Biliary sludge formation during enteral nutrition: prevalence and natural history.

BACKGROUND: Total parenteral nutrition is an etiologic factor in the formation of biliary sludge. We studied whether enteral nutrition is also a risk factor for sludge. METHODS: Fifty patients with a needle catheter jejunostomy (NCJ) placed during a major abdominal operation underwent preoperative and weekly postoperative ultrasonography until NCJ feedings were discontinued (1 to 6 weeks). RESULTS: All patients were men. The mean age was 63.2 +/- 1.6 years. Fourteen asymptomatic patients (28.0%) had biliary sludge within 2 weeks of beginning enteral feedings through a NCJ. Complete ultrasonographic resolution of sludge was observed in 13 of the 14 positive patients within 1 to 2 weeks of resuming an oral diet. One patient was lost to follow-up after 14 week; a positive sonogram had persisted but the patient remained asymptomatic. During the period of observation, no other patient had signs of biliary tract disease. CONCLUSIONS: (1) Biliary sludge may form in some patients during enteral feeding with NCJ. (2) Sludge is cleared by the gallbladder once an oral diet is resumed. (3) There appears to be little risk of complications during postoperative enteral feeding.

Abdominal operations after lung transplantation. Indications and outcome.

OBJECTIVE: To assess the outcomes of abdominal operations in patients with lung transplants and identify adverse risk factors. DESIGN: Matched cohort study. SETTING: University referral center. PARTICIPANTS: Twelve lung transplant recipients who required abdominal operations (hereafter referred to as case patients) and 12 age-, sex-, and pulmonary diagnosis-matched lung transplant recipients who had not undergone an abdominal procedure (hereafter referred to as control patients). INTERVENTIONS: Elective abdominal operations including laparoscopic cholecystectomies (n = 5), laparoscopic repair of a colovaginal fistula (n = 1), and open colectomy for a benign colovesical fistula (n = 1) and urgent operations including bowel resections (n = 3), subtotal pancreatectomy (n = 1), and hepatorrhaphy for an iatrogenic liver injury (n = 1). MAIN OUTCOME MEASURES: Morbidity and mortality. RESULTS: Abdominal operations were performed in 12 (11%) of the patients undergoing lung transplantation at the university referral center since 1987, with an associated mortality rate of 25%. Morbidity and mortality rates of electively performed procedures were 28% and 14%, respectively. An urgent indication for abdominal procedure was associated with 100% morbidity and 40% mortality. Compared with a matched group of 12 control patients, the long-term survival of the case patients was reduced (18% vs 64% at 4 years). Case patients undergoing an abdominal procedure in the posttransplantation period tended to have a higher prevalence of previous rejection (67% vs 25%), a higher perioperative steroid dosage (53 mg/d vs 36 mg/d), and a significantly lower posttransplantational forced expiratory volume in 1 second (FEV1, 1.23 L vs 1.91 L; P < .05). CONCLUSIONS: Elective abdominal operations are relatively safe in properly prepared lung transplant recipients. However, laparotomy for urgent surgical conditions is associated with increased morbidity and mortality rates caused in part by the magnitude of the abdominal operation and influenced by the status of the lung transplant as manifested by previous rejection episodes, perioperative steroid dosages, and FEV1 values.

Incidence and significance of subdiaphragmatic air following laparoscopic cholecystectomy.

Subdiaphragmatic free-air may be indicative of a perforated viscus; however, it is normally present after open abdominal surgery. The objective of this study was to determine the significance and incidence of subdiaphragmatic free air following laparoscopic cholecystectomy (LC). Cases of intestinal perforation following laparoscopic cholecystectomy from 1991 to 1995 at The University of Texas Health Science Center at San Antonio were reviewed and their association with subdiaphragmatic free air was determined. Twenty-five patients undergoing LC and 20 patients undergoing open cholecystectomy (OC) were prospectively evaluated with chest radiographs to determine the incidence and quantity of nonpathologic postoperative free air. Four cases of intestinal perforation resulting from trocar injuries or electrocautery burns occurred among 1603 LCs during this study period, for an incidence of 0.2 per cent. Three of the four patients with perforations were diagnosed postoperatively (2-5 days), and two patients had a moderate volume of subdiaphragmatic free air that aided the diagnosis. The incidence of subdiaphragmatic air following LC was 24 per cent, compared to 60 per cent for OC (P < 0.05). Eighty-three per cent of patients with retained air after LC had a minimal volume, compared to 67 per cent of patients after OC (P < 0.05). Nonpathologic subdiaphragmatic free air may normally be present following laparoscopic cholecystectomy but is uncommon 24 hours after the operation. When present, only a small volume is usually detectable. In the rare situation of intestinal perforation resulting from LC, subdiaphragmatic free air may be an important diagnostic finding.

Complications of surgical endoscopy. A decade of experience from a surgical residency training program.

BACKGROUND: This study examines the notion that gastrointestinal endoscopy performed by supervised surgical residents is safe. METHODS: We reviewed all gastrointestinal endoscopic procedures performed by surgical residents with faculty supervision for complications and deaths occurring up to 30 days following the procedures. RESULTS: The overall complication rate for 9,201 upper and lower endoscopy procedures was 1.4% and 0.42%, respectively. Overall mortality rate was 0.76% for upper endoscopy and 0.6% for lower endoscopy. No mortality was a direct result of a procedure-related complication. Intestinal perforation, drug overdose, bleeding, and aspiration were the most common procedure-related complications. Each resident completed an average of 75 upper endoscopies and 79 lower endoscopies during their training period. CONCLUSIONS: Gastrointestinal endoscopy can be performed safely by surgical residents with appropriate supervision. The higher morbidity and mortality of upper endoscopy are most likely related to the underlying disease rather than the procedure. Awareness of common complications and application of appropriate precautions and instruction are critical for minimizing complications.

Laparoscopic cholecystectomy during pregnancy is safe for both mother and fetus.

The use of laparoscopic cholecystectomy in pregnant women has been slow to gain wide acceptance for two reasons: one is the potential for mechanical problems related to the pregnant uterus and the other is fear of fetal injury resulting from instrumentation or the pneumoperitoneum. To assess the effects of laparoscopic cholecystectomy on both the mother and the unborn fetus, we reviewed our surgical experience over a 5-year period analyzing indications for the procedure along with complications and outcome. During this 5-year period, 22 patients ranging in age from 17 to 31 years underwent laparoscopic cholecystectomy during pregnancy. Gestational ages ranged from 5 to 31 weeks with two patients being in the first trimester, 16 in the second, and four in the third. The primary indications for surgical intervention were persistent nausea, vomiting, pain, and inability to eat in 17 patients, acute cholecystitis in three, and choledocholithiasis in two. In all patients a pneumoperitoneum was established by means of a closed technique starting in the right upper quadrant of the abdomen. Two of the 22 patients also underwent successful transcystic common bile duct exploration with removal of common duct stones. All 22 patients survived the surgical procedure without complications, and there were no fetal deaths or premature births related to the procedure. Based on the preceding results, it would appear that laparoscopic cholecystectomy during pregnancy is safe for both the mother and the unborn fetus. Indications for this procedure should include stringent criteria such as unrelenting biliary tract symptoms or the complications of cholelithiasis. If at all possible, when laparoscopic cholecystectomy is indicated, it should be performed either in the second trimester or early in the third.

Upper gastrointestinal bleeding following major surgical procedures: prevalence, etiology, and outcome.

With continuing improvements in the medical therapy of peptic ulcer disease, the incidence of primary upper gastrointestinal bleeding (UGIB) has markedly declined. Nonetheless, in a subset of surgical patients, secondary UGIB following a major operation may still be a source of substantial morbidity. To further elucidate this problem, we reviewed 103 cases of overt UGIB following all major surgical procedures conducted in two hospitals between July 1982 and June 1994. The prevalence of postoperative UGIB during this period was 0.39%. The mean interval between initial operation and UGIB was 16 days (range 1-55 days) and there was a high incidence of associated sepsis (26%). The source of bleeding was defined endoscopically in all cases and included gastritis (69.9%), solitary ulcers (17.5%), and other causes (12.6%). Postoperative UGIB (nonvariceal) was most commonly seen following portacaval shunting operations but mortality rates were highest in patients who developed UGIB after cardiovascular operations. We conclude that: (1) postoperative UGIB has become a relatively uncommon but still formidable clinical problem; (2) erosive gastritis continues to be the major source of UGIB but acute ulcers, varices, and other causes contribute to the total; and (3) postoperative UGIB is most likely to be fatal in cardiovascular patients and those who develop concurrent sepsis and/or multiorgan failure.

Complications of needle catheter jejunostomy in 2,022 consecutive applications.

BACKGROUND: We commonly use needle catheter jejunostomy (NCJ) for early enteral feeding in selected patients. Review of our approach was prompted by the suggestion that enteral feeding represents a "stress test" for the bowel and may be associated with a high complication rate. MATERIALS AND METHODS: We reviewed patients with NCJ inserted over the past 16 years by prospective database, chart review, and conference minutes, with emphasis on complications. RESULTS: During the conduct of 28,121 laparotomies, 2,022 NCJs inserted in 1,938 patients (7.2%) resulted in 34 NCJ-related complications in 29 patients (1.5%) The most common complication was premature loss of the catheter from occlusion or dislodgment (n = 15; 0.74%), and the most serious was bowel necrosis (n = 3; 0.15%). CONCLUSIONS: Needle catheter jejunostomy may be inserted and used with a low complication rate. Most complications were preventable through greater attention to detail and better monitoring of physical examination of patients with marginal gut function.
