Laparoscopy in perforated gastroduodenal ulcers

The authors have performed operations on 32 patients with perforated ulcers of the duodenum and 7 patients with perforated ulcers of the stomach. The diameter of the perforations was 2-8 mm. In 10 of the 39 patients the perforation defects could not be sutured by the laparoscopic method. The authors consider that of great significance for the decision to make laparoscopic operations was the diagnosis of peritonitis, size and localization of the perforation, the surgeon's experience with endoscopic operating. The technique of laparoscopic suturing the perforations is described. Special attention is paid to the special disposition of the surgeon and his assistant at the operating table.     

Laparoscopic surgery of perforated duodenal and gastric ulcers

During the period of 13 months, the authors have operated on seven patients with perforated gastroduodenal ulcers. All surgeries were completely performed by the laparoscopic method. The laparoscopic suture of perforated ulcers was performed with lavage and only in one case it involved omentoplasty. The healing process was free of any complications in all patients. The advantage of laparoscopic operations of perforated ulcers resides in fast convalescence and in the fast restoration of working abilities. This method is appropriate in cases when the surgeon performing laparoscopic surgeries has sufficient experience in coincidence with the treatment of perforated ulcers.     

Epidemiology of sexually transmitted diseases in the catchment area of the Rostock University Dermatology Clinic after 1945

BACKGROUND: The purpose of this study is to evaluate the possibility, safety and advantages of laparoscopic approach in the diagnosis and therapy of perforated peptic ulcer. METHODS: This is a retrospective study including 69 cases of gastroduodenal perforation initially treated laparoscopically. The safety (morbidity and mortality) was estimated according to the two mortality rates fixed for laparotomies, APACHE II and Mannheimer Peritonitis Index (MPI). Sixty-nine patients (average age: 52 years), 23% of whom being over 70 years old, suffering from gastroduodenal perforation, were initially treated with laparoscopy. RESULTS: The laparoscopic diagnosis was done in 91% of cases. When the perforation was localized, the laparoscopic treatment was possible in 94% of cases. In 93% of cases a simple closure of the ulcerated perforation was performed. The conversion ratio was of 16%. One-hundred minutes (55-180) was the average operating. The morbidity was of 13%. One septic shock was reported in a patient with general purulent peritonitis diagnosed with laparoscopy and, after having converted, it was treated with laparotomy. No malignant iperCO2 was relieved. The reported mortality was of 4.3%, the theoretical mortality estimated was of 6% (MPI) and of 14% (Score APACHE II). The 3 deceased (87, 87 and 93 years old) had ASA index superior to 3. The remarkable advantage of laparoscopic approach is, in addition to diagnostic contribution, the absence of wall complications when the operation is not converted. CONCLUSIONS: The laparoscopic approach is suggested in gastroduodenal perforation, since it allows an etiological diagnosis and a treatment without conversion in 84% of cases.     

Dynamic phenotypic restructuring of the CD4 and CD8 T-cell subsets with age in healthy humans: a compartmental model analysis

The incidence of ulcer perforation in 1480 patients treated in the Bergen area of Norway between 1935 and 1990 was analyzed for daily (circadian), weekly (circaseptan), and yearly (circannual) time effects. A circadian rhythm was found overall that was reproducible and fairly stable across seasons, decades, and days of the week. After subgrouping, a circadian rhythm was found in younger patients, males, and duodenal perforations, while a 12 h (circasemidian) rhythm characterized ulcer perforation for women and for gastric ulcers. Duodenal perforations showed highest incidence in the afternoon, while gastric perforations showed a major peak around noon and a secondary peak near midnight. For duodenal ulcer perforation, the circannual pattern was characterized by a 6-month rhythm, with significantly higher incidence in May-June-July and in November-December in most subgroups. A circaseptan rhythm was not found, but there was a significantly higher incidence on Thursday-Friday as compared to Sunday-Monday. The pathophysiological mechanisms underlying the perforation of an ulcer thus seemed to show pronounced circadian and 6-month rhythmic variations, much less so circaseptan or circannual rhythms. While it is likely that exogenous environmental and/or societal factors play a significant role, variations in ulcer perforation may be related to endogenous biological rhythms in pathophysiological factors since the circadian pattern of duodenal perforation follows that for gastric acidity. Knowledge of the temporal patterns in peptic ulcer perforation and associated pathophysiologic factors should prove useful in optimizing the chronotherapeutic management of ulcer disease.     

Long-term follow-up of childhood duodenal ulcers

PURPOSE: This study reports the long-term results in children who have duodenal ulcers diagnosed by endoscopy who were treated with H2-receptor antagonist. METHODS: The medical records of 32 children admitted into The Queen Mary Hospital with endoscopically proven duodenal ulcers between 1975 and 1988 were reviewed to evaluate the long-term outcome of childhood duodenal ulcers after initial treatment with H2-receptor antagonist (H2RA). Follow-up details were updated and patients who had been lost to follow-up were recalled. The age of the 22 boys and 10 girls at the time of diagnosis of the ulcers ranged from 3 to 16 years (mean, 11.8 yrs). The duration of follow-up ranged from 8.5 to 21 years (mean, 11.6 yrs). RESULTS: Their primary presentations included epigastric pain (n = 9, 28.0%); nonsteroidal antiinflammatory drug (NSAID)-induced gastrointestinal bleeding (GIB, n = 6, 18.7%); unprovoked GIB (n = 12, 37.5%); perforation (n = 4, 12.5%); and pyloric obstruction (n = 1, 3.0%). All 13 patients who had NSAID-induced ulcers (pain and bleeding) responded to H2RA therapy and required no further treatment. All 14 patients who had unprovoked ulcers who presented with pain or bleeding did not respond to H2RA treatment. Ulcer healing was achieved only after eradication of Helicobacter pylori with antibiotics (n = 8) or definitive surgery involving either truncal vagotomy and pyloroplasty (VP, n = 4) or proximal gastric vagotomy (PGV, n = 2). The patient who had gastric outlet obstruction had vagotomy and antrectomy. All four patients who had perforation were initially treated with patch repair, but two had persistent ulceration despite H2RA treatment and required PGV. Complications developed in none of the four patients who had PGV, whereas two of the four patients with VP had problems (diarrhea, n = 1; bezoar obstruction, n = 1). CONCLUSIONS: Unprovoked childhood duodenal ulcer is associated with significant long-term morbidity and requires continued follow-up. The majority of the ulcers are resistant to H2RA treatment alone and ultimately require either eradication of H. pylori or surgery. In the absence of obstruction, PGV may be enough to resolve the ulcer diathesis.     

Laparoscopic suture closure of perforated peptic ulcer. A nonrandomized comparison with open surgery

BACKGROUND: Laparoscopic vs open suture in the surgical treatment of perforated peptic ulcer were compared in a retrospective study. METHODS: The outcome of 10 patients having the laparoscopic procedure was compared with the outcome of 17 patients treated with suture via laparotomy during the same time period. RESULTS: The mortality rate and the complication rate were comparable. The laparoscopic procedure was more time consuming; hospital stay did not differ. CONCLUSIONS: The results indicate that surgery for perforated peptic ulcer can be performed with the laparoscopic technique with an outcome comparable to open surgery. No obvious advantages to the patient were noted with the laparoscopic method.     

Laparoscopic appendectomy is an acceptable alternative for the treatment of perforated appendicitis

BACKGROUND: Ever since laparoscopy was first applied to the treatment of appendicitis, a controversy has existed as to whether the acknowledged benefits of a minimally invasive approach warrant its preference over the conventional treatment, which historically has had relatively low morbidity. The purpose of this study was to determine if laparoscopic appendectomy should be performed preferentially in cases where surgeons are not limited by technical constraints. METHODS: A retrospective chart review was performed of 112 patients operated on for suspected appendicitis from June 1995 to July 1996. Forty-eight patients underwent laparoscopic appendectomy, and 64 had conventional open appendectomy. Laparoscopic appendectomy was performed using a three-trocar technique and the endoscopic stapler. Results: The histopathological diagnosis of appendicitis was confirmed in 82.6% of cases. Overall, laparoscopic appendectomy reduced length of hospital stay (1.54 versus 4.09 days; p < 0.0001) compared to conventional open appendectomy, with no significant difference in hospital cost ($6430 versus $6669; p = ns). Although the total OR time was longer in the laparoscopic group (75.8 versus 60.2 min; p < 0.0001), laparoscopy resulted in both a reduction in length of stay (2.17 versus 6.27 days; p < 0.0001) and hospital cost ($7506 versus $10,504; p < 0.02) for cases of perforated appendicitis. Conversion to open appendectomy was performed in 6% of patients, all of whom had perforated appendicitis. CONCLUSIONS: Our data suggest that most cases of acute appendicitis with suspected perforation could be managed laparoscopically. Laparoscopic appendectomy significantly reduces length of stay and hospital costs in patients with perforated appendicitis.     

A three-day octreotide-containing helicobacter pylori eradication therapy for cure of peptic ulcers

BACKGROUND/AIMS: Octreotide is used to arrest peptic ulcer hemorrhage. Since it has anti-secretory properties, it could also be used in Helicobacter pylori eradication therapy, to cure peptic ulcer before discharging patients from hospital. The aim of this pilot study was to determine safety and efficacy of an ultra short quadruple octreotide containing H. pylori eradication therapy in patients with peptic ulcer. METHODOLOGY: Twenty-six consecutive symptomatic H. pylori-positive patients with duodenal (n = 20) or gastric ulcer (n = 6), were treated with a three-day course of octreotide 0.3 mg/day subcutaneously, amoxicillin plus metronidazole 2 g/day orally and colloid bismuth subcitrate 480 mg/day. CLO-test, culture and crush tissue smears were performed on admission to the study, at 4 and 8 weeks post treatment. The effect of octreotide on intragastric pH (n = 10) was also investigated. RESULTS: Octreotide significantly increased the mean 24-hour intragastric pH > 3 over 68.9% of the time (37.1%-99.5%). There were no treatment side effects. Ulcer pain was abolished at between 2-12 days. By intention-to-treat 24/26(92.3%, 95% CI 82%-100%) ulcers had healed at 4 weeks. H. pylori eradication rate at 8 weeks was 88.5% (23/26) (95% CI 76%-100%). CONCLUSIONS: Our ultra-short octreotide containing quadruple therapy is a safe and effective regime in eradicating H. pylori and healing peptic ulcers. It may be a suitable therapy for hospitalized patients with peptic ulcer hemorrhage.     

Perforated duodenal ulcer: an alternative therapeutic plan

An alternative plan for the treatment of a perforated duodenal ulcer is proposed. We will focus on the now-recognized role of Helicobacter pylori in the genesis of the majority of duodenal ulcers and on the high rate of success of therapy with a combination of antibiotics and a proton-pump inhibitor or histamine2 blocker in treatment of such ulcers. Knowledge that half the cases of perforated duodenal ulcer may have securely sealed spontaneously at the time of presentation is incorporated in the therapeutic plan. Patients with a perforated duodenal ulcer who have already been evaluated for H pylori and are not infected or, if infected, have received appropriate therapy should undergo an ulcer-definitive operation if they are suitable surgical candidates. Most authorities recommend surgical closure of the perforation and a parietal cell vagotomy. The remaining patients should have a gastroduodenogram with water-soluble contrast medium. If the perforation is sealed, the patient can be treated nonsurgically. If the perforation is leaking, secure surgical closure of the perforation is necessary. Following recovery from the immediate consequences of the perforation, evaluation for H pylori should be conducted. If the patient is infected, combined medical therapy is recommended. If the patient is not infected, Zollinger-Ellison syndrome should be ruled out and medical therapy is recommended if the ulcer has not been treated previously. Elective ulcer-definitive surgery should be considered for the occasional uninfected patient who has already received appropriate medical therapy for the ulcer.     

Communicable disease in African immigrants in Minneapolis

To perform a laparoscopic appendectomy, three trocars are usually needed. In order to reduce abdominal wall trauma, we have adopted an umbilical one-puncture laparoscopic-assisted appendectomy (UOPLAA). We did a retrospective study of UOPLAA performed during last 2 years on 200 children aged from 5 to 18 years (median, 9 years). The patients were selected after clinical examination. No child with advanced generalized peritonitis or an abscess with a palpable mass was a candidate for this technique. UOPLAA was successful in 184 patients (92%). In 16 cases (8%), an additional trocar was required to manage perforated or retrocecal appendicitis. The mean operative time was 15 min, and the mean hospital stay was 2 days. There were no intraoperative complications. There were 10 (5%) postoperative complications (three parietal and seven intraabdominal). Four patients (2%) needed reoperation under general anesthesia. The UOPLAA is our preference in cases of acute nonperforated appendicitis because it is simple and fast, with good cosmetic results; but in 8% of our cases, an intraoperative difficulty (retrocecal location, abnormal adhesive band, peritonitis, etc.) arose that required the introduction of additional devices to ensure the safety of the laparoscopic procedure.     

Nissen fundoplication by laparoscopy

Short term results following laparoscopic Nissen fundoplication were evaluated in 31 patients with symptomatic gastroesophageal reflux. 6 were females and 26 males, and they ranged in age from 5 months to 64 years (mean: 4.9 years in 19 younger than 18 years, and 39.3 years in 12 adults). Most of the adults who complained of pain and heartburn underwent pH monitoring, endoscopy, and manometry as needed. Milk scan was the most useful diagnostic tool for the evaluation of the children, who suffered mainly from gastroesophageal-related pulmonary disease. Indications for laparoscopic operation were identical with those for conventional open Nissen fundoplication. 1 case of dysautonomia died postoperatively; the rate of complications, mostly minor, was 22.5%. 3 patients required conversion to open Nissen fundoplication due to cardiorespiratory instability secondary to pneumothorax in 2, and to esophageal perforation in the third. 5 adults developed temporary dysphagia. 3 children had only partial improvement in their pulmonary disease following the operation, while the other 15 had complete relief. The total time for the laparoscopic operation averaged 245 minutes in adults, and 228 in children. Discharge was usually on the fourth postoperative day in adults (mean: 6.0 days). Regurgitation and heartburn were cured in 10 out of 11 adults (91%). All parents of children were satisfied. Symptomatic outcomes following laparoscopic Nissen fundoplication compare favorably with those of open surgery with respect to mortality, complications, and outcome.     

Perforated appendicitis in children: risk factors for the development of complications

BACKGROUND: Many aspects of the management of perforated appendicitis in children remain controversial. The objective of this study was to define risk factors associated with the development of postoperative complications in children undergoing treatment for perforated appendicitis. METHODS: We reviewed all children (age < 16 years) who were treated for perforated appendicitis at Cardinal Glennon Children's Hospital between 1988 and 1997. Inclusion criteria included either gross or microscopic evidence of appendiceal perforation. RESULTS: Of 285 children with perforated appendicitis, 279 underwent immediate operative treatment. Mean patient age was 7.7 years and there were no deaths. Major postoperative complications included intra-abdominal abscess (n = 17), ileus (n = 7), mechanical intestinal obstruction (n = 6), and wound infection (n = 4). All children who had a postoperative abscess had more than 5 days of symptoms before operation. Within this subgroup, drain placement was associated with not only decreased postoperative abscess formation and but also shorter duration of fever and length of hospitalization. The incidence of mechanical obstruction or ileus was not increased and the rate of wound infection was actually lower after drainage. CONCLUSIONS: Drain placement appears to be helpful in children with late diagnosis but is of little benefit when the duration of symptoms is less than 5 days. Thus it is likely that drains are most useful in patients with well-established and localized abscess cavities.     

Perforated peptic ulcer: a comparison of long term results following partial gastric resection or simple closure

The results of simple closure were compared with those of partial resection in the treatment of perforated peptic ulcer. The investigation was carried out 7-13 years after the primary operation on 126 patients who had been allotted to one of the two treatment methods on the basis of an almost randomized schedule. Better late results were obtained with partial resection than with simple closure in patients in the age range 50-59 years at operation, with short duration of perforation and with a long history of symptoms before perforation. None of the patients treated with partial resection later underwent surgical treatment for recurrence of symptoms. In the simple closure group 27.3 per cent needed further surgery at 3 months to 10 years after perforation.     

Association of CD4+ T cell-dependent keratitis with genetic susceptibility to Pseudomonas aeruginosa ocular infection

The role of T lymphocytes in susceptibility to Pseudomonas aeruginosa corneal infection was studied in inbred C57Bl/6 (B6) beta2-microglobulin+/+ (beta2m+/+) and beta2m-/- knockout (KO) mice on a B6 genetic background. The corneas of both B6 and KO mice perforated by 7 days postinfection (p.i.). Histopathology revealed a similar inflammatory response characterized by an infiltration of polymorphonuclear neutrophilic leukocytes by 24 h p.i. in both groups of mice. CD4+ and CD8+ (latter absent in KO) T cells were present in cornea by 3 days p.i., and by 5 days, IL-2R-positive cells were positively immunostained. Corneas of B6 beta2m+/+ mice depleted of CD4+ T cells and infected with P. aeruginosa did not perforate at 7 days p.i. vs mice depleted of CD8+ T cells or treated with an irrelevant mAb. Neutralization of IFN-gamma before infecting B6 mice prevented corneal perforation and was associated with a lower delayed-type hypersensitivity than in B6 mice similarly treated with an irrelevant mAb. These data provide evidence that a CD4+ T cell (Th1)-dominated response following P. aeruginosa corneal infection is associated with genetic susceptibility and corneal perforation in inbred B6 mice.     

Three major coronary artery-to-left ventricular shunts: report of three cases and review of literature

The gallbladder is perforated and stones are spilled more frequently during laparoscopic cholecystectomy than during open cholecystectomy. Recent reports have implicated spilled gallstones as a source of infrequent but serious complications of laparoscopic of laparoscopic cholecystectomy. They can cause serious morbidity, and in most cases the patient will require open surgery for management of these complications. The authors report the case of a patient who was ill for 14 months after laparoscopic cholecystectomy when spilled stones formed a nidus for intra-abdominal abscess and colocutaneous fistula. Every effort must be made to prevent gallbladder perforation. When it does occur, all stones should be retrieved. Attempts at repairing gallbladder perforations are often unsatisfactory. A simple solution to this potential problem is to retrieve all stones immediately, place them in an intraperitoneal specimen bag, and "park" the bag on the liver. As soon as the gallbladder is dissected off the liver it should be placed in the specimen bag with the stones and removed through the umbilical port opening.     

Peptic ulcer in Greenland Inuit: evidence for a low prevalence of duodenal ulcer

In an eight years period new peptic ulcer was diagnosed in 127 Inuit patients at the Central Hospital, Dronning Ingrids Hospital, Nuuk/Godth?b. The ratios: duodenal ulcers (DU): prepyloric ulcers (PPU): gastric ulcers (GU) were 17:22:88. The male:female ratio was 2:1. 46 of the patients were living permanently in Nuuk, 81 in The Districts. There were no significant differences in the type of ulcers among the two groups. The incidence of GU among the Nuuk population was comparable to the incidence in the Danish population (0.63/1000 inhabitants per year), whereas the mean age at the time of diagnosis was only 45 years, thus the patients were approximately 15 years younger than the Danish counterparts. The incidence of DU among the Inuits was 0.15/1000 inhabitants per year, significantly less than in the Danish population. The frequency of Helicobacter (H.) pylori infection among 56 Inuits with dyspeptic symptoms was: 0.61. Only 6/12 patients suffering from DU had a positive test for H. pylori infection. Conclusions: The incidence of duodenal ulcers in the Inuit population was only 10% of the incidence in a Danish population, whereas the incidence of gastric ulcers among the Inuits was comparable to the incidence among Danes. Only 50% of Inuit patients with proven DU had a positive test for H. pylori infection, whereas the frequency of H.pylori infection in a population with dyspeptic symptoms corresponded very well to the frequency reported from other populations.     

The aminolysis of beta-phenylglycide esters. 3. Chemical structure proof

Peptic ulcer in pregnancy and its complications, though rare, can be life-threatening to mother and fetus. Perforated peptic ulcer in pregnancy is extremely rare; when this occurs survival of both mother and child is unusual. Only five cases of maternal survival following perforation of a peptic ulcer have previously been recorded and, of these, only three were associated with survival of both mother and infant. The authors report an additional case of perforated ulcer in pregnancy with survival of mother and infant, and review the relevant literature. Early surgical diagnosis and treatment followed by vaginal delivery of the fetus offers the best hope for survival of mother and child.     

Prognostic factors and scoring systems in myelodysplastic syndromes

The treatment of peptic ulcers has been revolutionized by the discovery that Helicobacter pylori (H. pylori) bacteria is a causative agent for ulcer formation. However, when patients present with dyspepsia or epigastric discomfort, more than 80% of patients will not have ulcer disease and empiric treatment of H. pylori is not recommended for these patients. Eradication of H. pylori has not been demonstrated to improve the symptoms of non-ulcer dyspepsia compared with non-ulcer dyspepsia patients treated with placebo. Therefore, we recommend that patients should first be evaluated for peptic ulcers with endoscopy or upper gastrointestinal series before the diagnosis and treatment of H. pylori. Generally, the treatment of H. pylori should be limited to patients with peptic ulcers, mucosal-associated lymphoid tissue lymphomas, and gastric cancers. Most diagnostic tests for H. pylori, including quantitative IgG antibody, urea breath tests, rapid urease tests (CLO), tests of gastric mucosal biopsies, and staining of gastric mucosal biopsies, have equivalent diagnostic characteristics. Therefore, the choice of diagnostic test for H. pylori should be based on cost, ease of use, and lack of complications. Multiple antibiotic regimens are available for the treatment of H. pylori. Triple antibiotic therapy is the least expensive but has the highest rate of side effects and the least compliance. Combining a proton pump inhibitor with clarithromycin and another antibiotic will eradicate H. pylori with fewer side effects and better compliance but this is the most expensive antibiotic regimen.     

COX-2 inhibition versus gastroprotection with dual COX inhibitors: an evidence-based approach

Highly selective inhibitors of cyclooxygenase-2 (COX-2i) were introduced to minimize peptic ulcers and their complications caused by dual COX inhibitors (COXi). Co-prescribing a (generally cheap) dual COXi with a gastroprotectant is an alternative strategy, proven to reduce the incidence of NSAID-associated endoscopic ulcers. This review compares the efficacies of these two strategies and makes some estimates of their relative cost-effectiveness. In standard risk patients, endoscopic ulcers are reduced to about the same extent (around 70-80%) by either co-prescribing omeprazole or lansoprazole with a dual COXi or preferring a COX-2i alone. COX-2i reduced ulcer complications by a weighted mean of around 60% in comparative studies with dual COXi. There is little information about the influence of PPI on this endpoint, although one study using H. pylori treatment as a possible surrogate for placebo intervention found 77% protection against recurrent upper gastrointestinal bleeding by co-administered omeprazole. One direct comparison of the two strategies in high-risk patients (recent ulcer bleed) found quite high rates of re-presentation with bleeding ulcer using either strategy, and the differences between them were not significant. Drug costs in four Western countries were compared for each strategy. In one, the costs were similar, but in the others the combination of a cheap dual COXi with omeprazole was usually more expensive than using a COX-2i. The safest strategy in highest risk patients may be to co-prescribe a gastroprotectant with a COX-2i, with resulting higher drug costs but possibly offset by savings in other health costs. The efficacy and cost-benefit of this alternative approach warrants investigation.     

Hemolytic anemia associated with lead poisoning from shotgun pellets and the response to Succimer treatment

The recent development of mini-invasive surgery includes appendectomy. We report our results of 4 years experience in this type of approach. We have operated on 154 patients (61 men, 93 women), mean age 26.7 years, presenting with clinical signs of appendicitis. The operation was completely carried out by laparoscopy in 144 cases, including treatment of abscess in 13 and peritonitis in 8 cases. Operation was converted into laparotomy in 10 cases, 4 of which because of some difficulty in appendix dissection. No deaths were recorded. Eight (5.2%) post-operative complications occurred: 4 infections of the trocar hole, one of which the cause of readmission; 3 cases of pain and fever (in one a re-laparoscopy was performed because of suspicion of leakage of the appendicular stump); 1 residual hematoma requiring second laparoscopy. Mean duration of hospitalisation was 4.9 days (range 2-25 days): at present, mean hospitalisation is 2 and 6 days respectively in cases with and without peritonitis. In conclusion, laparoscopic appendectomy appears to be feasible in the majority of cases, with better results when the appendix is ectopic and/or in the presence of peritoneal reaction.
