Laparoscopic esophagomyotomy and antireflux procedure with intraoperative manometry

We have been routinely performing laparoscopic cholecystectomy and antireflux procedures. Having this experience, we decided to assess the feasibility and safety of performing a laparoscopic esophagomyotomy and antireflux procedure. Here we present a case of a 37-year-old man with a history of progressive dysphagia and a diagnosis of achalasia, made on the basis of clinical, endoscopic, and manometric studies. Preoperative manometry reported a pressure of 52 mm Hg (normal, 15-25 mm Hg) for 4.5 cm (normal, > 3 cm). Laparoscopic esophagomyotomy and anterior fundoplication were performed. The esophagomyotomy included a 6-cm segment of distal esophagus and 2 cm of stomach; postoperative manometry was 18 mm Hg for 3 cm. Eight months postoperatively, a barium swallow demonstrated no reflux. Laparoscopic esophagomyotomy and antireflux procedure can be performed with efficacy and safety, with the advantage of a shorter hospitalization and an early recovery compared with the traditional procedure. Also, we emphasize the importance of the intraoperative manometry in the relevance of a concomitant antireflux procedure.     

Jejunal interposition for peptic stenosis of the esophagus following esophagomyotomy for achalasia

We compared the prognostic significance of prior angina pectoris in 151 patients > or = 75 years of age admitted for acute myocardial infarction. There was a similar in-hospital course, but the long-term outcome was poorer in patients with prior angina.     

Laparoscopic approach in the surgical treatment of non-advanced achalasia]

A 23-year-old woman presented with a 10 year history of excessive sweating (hyperhidrosis), mostly in the axillae, and to a lesser extent the groin and hands. Initial treatment with a sedative antihistamine and topical Driclor (aluminium chloride hexahydrate in 2% alcohol) for 14 weeks resulted in no improvement. Axillary liposuction, a short and simple procedure, then produced a very satisfactory result.     

Laparoscopic myotomy for primary esophageal achalasia: prospective evaluation

BACKGROUND/AIM: The feasibility and safety of the laparoscopic myotomy having been previously demonstrated, the purpose of this prospective study was to evaluate its effectiveness. MATERIALS AND METHODS: Eight patients with primary esophageal achalasia underwent a laparoscopic modified Heller's myotomy with a posterior fundoplication. Early post-operative course has been uneventful in all cases. Clinical, endoscopic, and manometric prospective evaluations were performed with a median follow-up of 21 months (range 4-40). RESULTS: Excellent or good clinical results were present in all cases. Endoscopic studies were normal in all cases and the post-operative esophageal manometry (n = 7) showed that the median pressure of the lower esophageal sphincter decreased to 8.5 mmHg (range 3-9) which was significant compared to the median pre-operative value of 35 mmHg (p < 0.01). CONCLUSION: Though this experience is limited, these mean-term results suggest that the laparoscopic myotomy is effective to treat achalasia. It combines the efficacy of surgery and the minimally invasive aspect of dilatations. Thus, a prospective controlled trial comparing laparoscopic myotomy and dilatations is needed.     

Laparoscopic pull-through procedure for Hirschsprung''s disease

BACKGROUND: We investigated the suitability of two commercially available in-vitro bleeding tests (IVBT), the PFA-100 and the Hepcon HMS, to predict blood loss following operations with extracorporeal circulation (ECC) and compared them with conventional coagulation studies. METHODS: In 40 patients subjected to elective open heart surgery with ECC a blood sample was taken before and after ECC to measure platelet count, prothrombin time, aPTT, D-dimers, fibrinogen, and PFA-100 and Hepcon HMS data. The postoperative blood loss was recorded hourly until removal of drains. RESULTS: A significant correlation was found between total blood loss (250-1750 ml) and the preoperative PFA-100 (r = 0.41, p = 0.022), the preoperative platelet count (r = -0.42, p = 0.007), the preoperative D-dimer concentration in the plasma (r = 0.41, p = 0.01), and duration of ECC (r = 0.35, p = 0.044). There was no significant correlation between blood loss and the Hepcon HMS system. CONCLUSIONS: Although a significant correlation was found between blood loss and the PFA-100 IVBT, the practical value of these tests in the clinical situation is limited due to a great variability in individual results.     

Botulinum toxin A for the treatment of achalasia

Pneumatic balloon dilatation of the esophagus is one of the current recommended treatment for achalasia. This procedure is associated with risks such as esophageal rupture. Surgery and percutaneous gastrostomy tube placement has been performed in severely affected individuals. The Botulinum Toxin A (BoTxA) is widely used to treat neuromuscular conditions in which spasticity is of concern. We present four cases in which BoTxA was used as an alternative of treatment and in which less invasive modalities were unsuccessful. The patients received a total of 80 units of BoTxA, applied to the submucosa in doses of 20 units in each predetermined quadrants to the lower esophageal sphincter. All patients demonstrated improvement of their symptoms without side effects in this study.     

Extravesical detrusor tunneling: a variant of antireflux procedure

Generalized inherited glucocorticoid resistance (GIGR) is a rare syndrome characterized by elevated levels of plasma cortisol but lacking the symptoms of Cushing's syndrome. Biochemically, the condition is characterized by a relative resistance to glucocorticoids that can be compensated for by the elevated levels of cortisol. The inheritance pattern of GIGR is incompletely understood, and one of the central questions is whether there is a correlation between genotype and phenotype. Analysis of mutations within the receptor resulting in relative glucocorticoid resistance has identified two regions of clustered mutations in the proximity of previously identified affinity-labeled residues, the putative steroid-binding site. In the majority of cases, the mutation affects steroid binding and transactivation to the same degree, with the exceptions suggesting an explanation for the variability of the clinical manifestations. From a clinical point of view, in addition to preexisting genetic resistance to glucocorticoids, it is important to consider acquired changes in glucocorticoid receptor (GR) gene structure and organization, including alterations of noncoding sequences, and the importance of the resultant mutations, deletions, and other changes affecting receptor function. Finally, studies of New World primates and cell lines derived from hematologic malignancies constitute animal and human models for the molecular basis of glucocorticoid resistance where a number of inherited and acquired mutations in the GR gene have been demonstrated.     

Selecting the surgical procedure for simple and complicated esophageal achalasia in children

BACKGROUND/PURPOSE: Surgical experience in children who have achalasia is limited. Surgical treatment requires esophagocardiomyotomy and an antireflux procedure. However, when these operations fail, other procedures are needed. To summarize the experience treating children who have this condition, the authors reviewed retrospectively all case histories of patients treated from 1971 to 1996 at their hospital. METHODS: Three boys and a girl, ranging in age from 18 months to 11 years, were treated. All had multiple previous dilatations. Two then underwent operation using an abdominal approach for a Heller procedure and a posterior fundoplasty (Guarner operation). Two children were previously treated in another hospital. One underwent a Heller operation complicated by perforation of the anterior mucosa. The other had undergone three previous abdominal approaches for esophagocardiomyotomy and a Nissen fundoplication. Symptoms persisted and imaging and endoscopy showed stenosis in both patients. In the first patient an esophagocardioplasty with transverse closure (Wendel procedure) and a posterior fundoplasty was performed. In the second child, the three previous abdominal surgical approaches mandated a transthoracic approach with transdiaphragmatic latero-lateral esophagogastric anastomosis (Heyrowsky operation) and a modified Guarner operation using the remaining fundus and gastric body. RESULTS: There were no intraoperative or postoperative complications. Follow-up time ranged from 3 months to 17 years. All patients experienced dramatic relief of symptoms and satisfactory weight gain. No recurrence of symptomatology has occurred. CONCLUSIONS: Esophagocardiotomy associated with an antireflux procedure may be the first option in the surgical treatment of children who have achalasia. However, if this fails, esophagocardioplasty and the latero-lateral esophagogastric anastomosis associated with antireflux procedure may be successful alternatives.     

Laparoscopic antireflux surgery and the thoracic surgeon: what now?

OBJECTIVE: Minimal invasive antireflux surgery is now a well accepted technique gaining a wide spread popularity. Simultaneously there is a growing tendency to fit all surgical candidates into one single type of operation, i.e. laparoscopic Nissen antireflux operation. This study evaluates the impact of this new technology on the strategy and practice of a major referral centre for antireflux surgery. METHODS: An analysis was made of indications for the different types of antireflux techniques performed between July, 1993 and 1995. If on Barium swallow the gastro-oesophageal (GO) junction proved to be reducible, a laparoscopic approach was proposed, if not, an open transthoracic access was preferred. RESULTS: One hundred and fifteen patients were operated. Fifty five patients underwent a minimal invasive approach: 49 Nissen (are the total fundoplication) and 3 Lind (are the partial fundoplication) operations through laparoscopy, 3 Belsey Mark IV through video assisted thoracic surgery (VATS). Sixty patients were treated by open surgery for following reasons: conversion to open surgery in 2 cases, redo surgery in 15 cases, previous other major abdominal surgery in 12, irreducible GO junction in 5, paraoesophageal or mixed type hernia in 12, Barrett and or oesophagitis IV in 4, combined antireflux surgery and feeding gastrostomy in 5, abdominal partial fundoplication by principle in 1, associated motility disorder in 1, combined reflux and gastric ulcer disease in 2, and severe emphysema in 1. In the laparoscopic series reflux control at 1 year post surgery as measured by 24 h pH study in 28 patients was obtained in 89.5%. One patient required a reoperation for symptomatic recurrence. CONCLUSIONS: (1) Laparoscopic antireflux surgery is a feasible and well accepted technique; (2) careful study of each individual patient is of paramount importance to choose the correct type of operation and access as well. Therefore, fitting every patient into a single type of operation, i.e. laparoscopic Nissen, should be avoided; (3) thoracic surgeons with a major interest in GO reflux disease should familiarize themselves with laparoscopic antireflux procedures.     

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.     

Laparoscopic Heller cardiomyotomy with intraoperative manometry in the management of oesophageal achalasia

Results of an ongoing clinical study treating achalasia patients with laparoscopic Heller myotomy and Dor anterior fundoplication are presented. 18 patients underwent surgery between August 1991 and July 1995. Completeness of myotomies and calibration of fundoplications were measured using intraoperative manometry. Only one intraoperative complication, a perforation of the mucosa sutured laparoscopically, was encountered. There were no surgical mortalities nor postoperative morbidities. Mean hospital stay was 3.4 days. Complete relief of dysphagia and modifications of radiological and manometric patterns were achieved in all patients. All patients remain asymptomatic at 2 to 48 months from surgery. These results compare favourably with those of traditional surgery and of pneumatic dilatation.     

Laparoscopic orchiopexy: procedure of choice for the nonpalpable testis?

PURPOSE: Multiple approaches exist for the management of the nonpalpable testis. With the use of diagnostic laparoscopy widely accepted in the setting of the nonpalpable testis we have found laparoscopic orchiopexy to be an efficient and logical extension. To evaluate its use we report our experience with laparoscopic orchiopexy to treat 44 nonpalpable testes in 36 patients. MATERIALS AND METHODS: We retrospectively reviewed the medical records of all patients who underwent laparoscopic orchiopexy for a 2 1/2-year period. Modifications of the surgical technique are described. RESULTS: The left testis was affected in 18 boys, the right in 9 and both in 9. At laparoscopy 8 testes were at the internal ring or were peeping and the remainder were intra-abdominal. One patient underwent a unilateral 1-stage Fowler-Stephens orchiopexy, and 3 unilateral and 1 bilateral 2-stage Fowler-Stephens orchiopexy. Two patients underwent laparoscopically assisted orchiectomy. The remaining 31 patients underwent laparoscopic orchiopexy without division of the spermatic vessels. At followup (mean 6 months) all testes are without atrophy, and 39 of 42 (93%) are in an acceptable scrotal position. There are 3 testes (7%) high in the scrotum. CONCLUSIONS: Laparoscopic orchiopexy is a logical extension of diagnostic laparoscopy for the evaluation and treatment of the nonpalpable testis. The low incidence of complications and 93% success rate underscore the feasibility of this procedure. It is our procedure of choice for the treatment of nonpalpable testis.     

Pneumatic dilatation is effective long-term treatment for achalasia

Although pneumatic dilatation (PD) has been an established treatment for achalasia for decades, there is limited information on its long-term clinical efficacy. We have followed up the clinical status of patients having PD with a 30- or 35-mm balloon by one of us (D.O.C.) over a 25-year period. Of 144 patients whose initial records were available for review, 31 could not be contacted. Of the remaining 113 patients, 72 (64%) responded to a questionnaire assessing swallowing status and patient satisfaction, and this forms the basis of this report. There were 32 men and 40 women, with mean age 46 years (range: 17-78); mean length of follow-up since PD was 6.5 years (range: 10 months to 25 years). Success was primarily defined by the need for no additional therapy for achalasia other than one or two PD's. PD was effective long-term treatment in 61/72 patients (85%); only four of these required a second PD over this time interval. There was no significant difference in any of the following parameters between patients with a treatment success or failure: age, sex, size of pneumatic dilator, and duration of symptoms prior to PD. Response was significantly better (P < 0.05) in patients having no prior dilatation (43/47; 91%) than in those in whom another physician had performed prior dilatation (18/25; 72%). In response to the question of whether they would select PD again, 68 patients (94%) responded positively. In conclusion, pneumatic dilatation performed using a consistent technique by an experienced physician is effective long-term therapy for achalasia patients of all ages. Most patients require only one dilatation.     

Pneumatic dilatation in the treatment of esophageal achalasia

The purpose of therapy in esophageal achalasia is to reduce the pressure at the level of the lower esophageal sphincter. In this study 26 patients (16 males and 10 females) between 30 and 50 years of age, affected by esophageal achalasia underwent esophageal dilatation with Rigiflex pneumatic dilators. A total of 40 dilatations were performed. A complete success using the Rigiflex pneumatic dilators, was achieved in 24 out of 26 patients (92.3%).     

Laparoscopic closure of esophageal perforation following pneumatic dilatation for achalasia. Report of two cases

Esophageal perforation following pneumatic dilation of the esophagus is normally recognized shortly after the event. Two patients with esophageal perforation were repaired utilizing a transabdominal laparoscopic technique with suture closure of the perforation, contralateral Heller myotomy, and Toupet posterior partial fundoplication. Patients recovered excellently, were started on liquids within 3 days of surgery, and were discharged shortly thereafter. Details of the procedure are presented. This minimally invasive approach is well tolerated and appropriate in selected patients.     

Laparoscopic diagnosis and treatment of an infarcted epiploic appendage

A patient experienced acute abdominal pain that was diagnosed at laparoscopy as being due to an infarcted epiploic appendage. To our knowledge, this is the second report of laparoscopic diagnosis and treatment of an epipolic disorder. Infarcted epiploic appendages may be associated with bowel obstruction and abscess formation. Therefore, they should be looked for at the time of diagnostic laparoscopy for acute abdominal pain of unclear etiology, and removed if present.     

Total duodenal diversion for treatment of reflux esophagitis uncontrolled by repeated antireflux procedures

The operations of Nissen, Hill, and Belsey are adequate in controlling esophaegeal reflux in the majority of patients. In a small percentage however, objective and subjective evidence of esophagitis persists in spite of repeated operations to restore lower esophageal sphincter competency. These failures are then usually treated by operative procedures of great magnitude involving organ interposition. Repeated antireflux operations directed to the gastroesophageal area may in some instances result in impairment of blood supply with an increased risk of both esophageal and gastric fistulae. In the past many observers have felt that reflux esophagitis resulted solely from the effects of acid-pepsin secretions bathing the distal esophagus. Recently experimental and clinical data have indicated the importance of duodenal contents in the etiology and perpetuation of reflux esophagitis. During a recent two year period, 6 patients with persistent reflux esophagitis uncontrolled by repeated antireflux procedures have been seen on our service. These 6 patients, underwent 12 unsuccessful antireflux operations elsewhere. Three of the 6 patients had also been subjected to vagotomy-antrectomy for a coexisting duodenal ulcer. A marked lowering of gastric acidity took place but esophageal reflux and esophagitis persisted. These three patients were treated on our service by takedown of the Billroth I anastomosis, closure of the duodenal stump and diversion of the duodenal contents into a Roux-en-Y limb. Three other patients who had undergone unsuccessful antireflux procedures alone were subjected to antral resection, Roux-en-Y diversion and transthoracid vagotomy. This simplified appraoch to the treatment of persistent esophageal reflux uncontrolled by repeated antireflux procedures has given satisfactory results. The operation should be considered when technical considerations preclude further surgical attempts to perform another effective antireflux operation. Total duodenal diversion should, however, not be considered as the primary operation for the patient suffering from reflux esophagitis. However, in circumstances discussed above this direct approach appears preferable to major resectional procedures.     

Laparoscopic Swenson pull-through: a comparison with the open procedure

This study was performed to compare the standard open Swenson pull-through (OSP) with the laparoscopic Swenson pull-through (LSP) for Hirschsprung's disease. The Swenson pull-through was performed on eight patients with a rectosigmoid transition zone, during a 14-month period, using one camera port and three working ports. The results were compared with those of 10 patients with a similar lesion treated by the open procedure during an overlapping 19-month period. One laparoscopic procedure was converted to the open version because of technical difficulties. Both methods had a hand-sewn anastomosis approximately 1 cm above the pectinate line. The preoperative variables of age, weight, incidence of colostomy, and incidence of Down's syndrome were similar for the two groups. The operating time for LSP was similar to that for OSP (4 hours 42 minutes v 4 hours 37 minutes, respectively: P = NS). Postoperatively, the laparoscopic group had a shorter hospital stay (5.25 v 8.8 days; P < .05) and had a shorter period until the start of oral intake (2.75 v 5 days; P < .05). The requirement for narcotic pain medication was similar (12.6 v 12.8 doses; P = NS). Early postoperative complications were more common in the open group (3 wound infections, 1 prolonged ileus, and 1 anastomotic leak). No complications occurred in the laparoscopic group. Late postoperative follow-up was too short to compare functional results. The authors conclude that the Swenson pull-through can be performed safely with the laparoscope, with reduced morbidity.     

Pediculated labial ureteroplasty: an original treatment procedure for ureteral lesions of obstetric origin

Destruction of the urethra is the most severe complication of pregnancy-related vesicovaginal fistula. Although uncommon in Europe, pregnancy-related urethral destruction is still observed in Africa. In this study we describe our experience with a new reconstruction technique using a pedunculated skin flap raised from the labia majora. Between January 1992 and June 1996 we treated 35 patients in the Urology Department of Niamey Hospital in Niger. All patients were black. Mean age was 18 years and mean follow-up was 19 months. Two plasty techniques were used, i.e. extension (16 cases) and tubulisation (19 cases). Urinary incontinence was treated using a suburethral loop system created using a fatty flap taken from the labia majora (Martius method). Urethrocervico-suspension of the vagina was necessary in 6 cases. Normal micturition with no leakage was obtained in 24 patients (68.6%) and functional improvement in 6 cases (17.1%) Treatment failed in 5 cases (4.2%). In comparison with previously reported techniques, urethral reconstruction using a pedunculated labial flap and suburethral looping system allows successful treatment of pregnancy-related urethral destruction in 70% of cases. This technique is particularly well suited for use in developing countries where occurrence of this complication is most frequent. However even with the greatest skill, creation of a physiologically perfect closure system is currently impossible.
