Abstract
Clinical studies indicate that cigarette smoking increases the risk for developing acute pancreatitis. The nicotine metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a major cigarette smoke toxin. We hypothesized that NNK could sensitize to pancreatitis and examined its effects in isolated rat pancreatic acini and in vivo. In acini, 100 nM NNK caused three- and fivefold activation of trypsinogen and chymotrypsinogen, respectively, above control. Furthermore, NNK pretreatment in acini enhanced zymogen activation in a cerulein pancreatitis model. The long-term effects of NNK were examined in vivo after intraperitoneal injection of NNK (100 mg/kg body wt) three times weekly for 2 wk. NNK alone caused zymogen activation (6-fold for trypsinogen and 2-fold for chymotrypsinogen vs. control), vacuolization, pyknotic nuclei, and edema. This NNK pretreatment followed by treatment with cerulein (40 μg/kg) for 1 h to induce early pancreatitis responses enhanced trypsinogen and chymotrypsinogen activation, as well as other parameters of pancreatitis, compared with cerulein alone. Potential targets of NNK include nicotinic acetylcholine receptors and β-adrenergic receptors; mRNA for both receptor types was detected in acinar cell preparations. Studies with pharmacological inhibitors of these receptors indicate that NNK can mediate acinar cell responses through an nonneuronal α(7)-nicotinic acetylcholine receptor (α(7)-nAChR). These studies suggest that prolonged exposure to this tobacco toxin can cause pancreatitis and sensitize to disease. Therapies targeting NNK-mediated pathways may prove useful in treatment of smoking-related pancreatitis.

Abstract
PURPOSE We describe a more efficient solution for calcium magnesium stones, an irrigation technique devised by us, and the indications for and results of our 20-year experience with direct renal or ureteral chemolysis. MATERIALS AND METHODS Renal and ureteral perfusion is performed with 2 coaxial catheters (where the interspace is 1-way circulation), a normal ureteral catheter to a nephrostomy tube or, if the ureter is impractical, a nephrostomy tube after inserting it in a thin catheter achieving coaxial circulation. The perfusion operates by gravity with continuous flow maintaining a negative pressure in the cavities and keeping the circuits sealed during treatment. All equipment is mounted on a mobile support which the patient can take anywhere in the hospital. RESULTS During the last 20 years 8 cystine stones and 20 "difficult" stones have been completely dissolved and the volume of 39 staghorn struvite stones has been reduced an average of up to 80% before 1 or 2 final lithotripsy sessions without significant side effects. Small fragments remained in the inferior calices in only 2 cases. CONCLUSIONS Chemolysis is useful for eliminating cystine stones as well as for cases in which lithotripsy or endourology is considered difficult or risky. Furthermore, chemolysis proved to be a useful method for reducing staghorn stones before performing lithotripsy.

Abstract
BACKGROUND The role of laparoscopic resection in the management of colon cancer is still a subject of debate. In this clinical study, we compared the perioperative results and long-term outcome for two unselected groups of patients undergoing either laparoscopic or open hemicolectomy for colon cancer. METHODS This prospective nonrandomized study was based on a series of 248 consecutive patients operated on by the same surgical team using the same type of surgical technique for right (RHC) and left (LHC) hemicolectomy, excluding segmental resections; the only difference was the type of access, which was either laparoscopic or open. The choice of type of access was left up to the patient after he or she had read the informed consent form. Operative time, length of stay, complications, and long-term outcome for the two groups were compared. Follow-up time ranged between 12 and 92 months (mean, 42). RESULTS Between March 1992 and January 2000, 140 patients underwent a laparoscopic hemicolectomy (55 RHC and 86 LHC); at the same time, 107 patients (44 RHC and 63 LHC) were treated via an open approach. There were no conversions to open surgery in the laparoscopic RHC group, but six patients (7%) in the laparoscopic LHC group were converted. The mean operative time for laparoscopic surgery was significantly longer than the time for open surgery (190 vs 140 min for RHC, 240 vs 190 min for LHC,); however, with increasing experience, this time decreased significantly. The mean hospital stay for the patients who underwent laparoscopic procedures was significantly shorter in both the RHC and the LHC groups (9.2 vs 13.2 days for RHC, 10.0 vs 13.2 days for LHC). No statistically significant difference between the two laparoscopic and open groups was observed for the major complication rate (1.9% vs 2.3% for RHC, 7.5% vs 6.3% for LHC). The patient in the laparoscopic RHC group were lost to follow-up. The local recurrence rate was lower after laparoscopic surgery in both arms (5.4% vs 9% for RHC, 1.5% vs 7.5% for LHC), but the differences were not statistically significant. Two port site recurrences were observed in the laparoscopic groups, one after RHC (2.7%) and one after LHC (1.5%). Metachronous metastases rates were similar for the two groups (16.2% vs 15.1% for RHC, 4.4% vs 5.7% for LHC). Cumulative survival probability at 48 months after laparoscopic RHC was 0.865, as compared to 0.818 after open surgery, and 0.971 after laparoscopic LHC, as compared to 0.887 after open surgery. CONCLUSION These results suggest that laparoscopic hemicolectomy for colonic cancer can be performed safely, with morbidity, mortality, and long-term results comparable to those of open surgery.

Abstract
Acute biliary pancreatitis (ABP) is a serious complication of biliary stones disease and is associated with significant morbidity and mortality. The role of ERCP in the management of ABP has been the focus of discussion in recent years. In this report, we evaluated a protocol of emergency Endoscopic retrograde Cholangiopancreatography (ERCP) (within 24 hours) and early ERCP (within 72 hours). From July 1997 to July 2000, were observed 45 patients (19 man and 26 women) with acute biliary pancreatitis. Mean age of patients was 63.4 years (range 21-87 years). Diagnosis of ABP was based on anamnesis and clinical assessment and was confirmed by specific laboratory data (hyperamylasemia, hyperlipasemia, total and fractionated bilirubinemia, gamma-GT, transaminase, alkaline phosphatase, hypocalcemia, hyperglycemia, leukocytosis). Ultrasound scanning within 24 h of admission was performed in 45 patients (100%) and it revealed gallbladder stones and muddy bile in 39 patients (87%). Computed tomography (CT) performed in all patients, showed a severe acute pancreatitis in the second or subsequent week following admission. The severity of acute pancreatitis was established by Glasgow's criteria and by clinical details of patients. ERCP and Endoscopic Sphinterotomy (ES) was performed in all 45 patients with acute biliary pancreatitis. Twenty-six patients (57%) were classified as having a severe attack (> 4) 19 as having a mild attack by Glasgow's criteria. ERCP associated with ES was performed within 24 hours in 22 patients (49%), 11 (50%) showed a severe attack and 11 (50%) showed a mild attack. A total of 2 complications (4%) occurred and the mortality was of 2 patients (4%). In 23 patients (51%) ERCP and ES was performed within 72 hours after conservative therapy, 8 (35%) showed a mild attack and 15 (65%) showed a severe attack. A total of 5 complications (9%) occurred and the mortality was of 3 patients (6%). Our study showed that ERCP with endoscopic sphincterotomy can be performed safely by skilled endoscopist, without adverse consequences soon after the onset of acute biliary pancreatitis even within the first 24 hours and it showed that is better than ERCP within 72 hours after conservative therapy.

Abstract
BACKGROUND/AIMS Laparoscopic cholecystectomy is a so called mini-invasive surgical procedure, and on this basis, we investigated whether and how the immune response is modified in patients after laparoscopic cholecystectomy compared to patients who underwent open cholecystectomy. METHODOLOGY In a prospective, nonrandomized trial, 35 patients underwent laparoscopic cholecystectomy and 31 open cholecystectomy. Immune activity (neutrophils, total lymphocytes, lymphocyte subpopulations, human leukocyte antigen (HLA-DR), interleukin 6, skin Multitest) was evaluated before surgery and respectively, 1, 3, and 6 days postoperatively. RESULTS One day after surgery, an increase in interleukin 6 (P < 0.01) was noted in patients who had undergone open cholecystectomy, while this parameter was almost unchanged in patients with laparoscopic cholecystectomy. Moreover, skin tests showed a hypo or anergic response in the majority (81.8%) of open cholecystectomy patients compared to laparoscopic cholecystectomy patients (10.5%), (P < 0.01). Finally, monocyte antigen HLA-DR was also reduced in open cholecystectomy patients (P < 0.05). In this group, we noted 2 cases (6.45%) of respiratory tract infection. CONCLUSIONS Even though laparoscopic cholecystectomy requires a longer surgery, it reduces postoperative pain, and hospitalization. It also facilitates rapid recovery, a return to normal activity, avoids postoperative immunosuppression and shows a better postoperative morbidity compared to open surgery.

Abstract
The authors report in a retrospective study their experience in the treatment of anal fistulas suggesting the total exercises of the fistula with primary closure of external and internal anal sphincters and rectal mucosa. In our department of surgery between 1987 and 1993, 36 patients (22 males and 14 females) with anal fistulas (17 intersphincteric, 15 trans-sphincteric and suprasphincteric) were treated with this technique. Postoperative in-hospital stay ranged between 2 and 5 days (mean 3.1) and surgical healing needed 12-15 days. A dehiscence of distal tract was observed in 3 cases (8.2%). in these cases secondary closure of the wound needed 24-28 days. All the patients controlled at follow-up (it lasted at least 1 year) did not show rectal incontinence for gas or stools. The authors conclude that total exeresis with primary closure is a safe procedure indicated in the treatment of anal fistula not associated to inflammatory bowel disease in consideration of earlier healing and minor costs.

Abstract
Disturbances of anal continence and evacuation are frequent. Numerous techniques are now available to measure anorectal function. There is also a better understanding of the anatomy and physiology of the pelvic floor which has a major role in anorectal function. ANORECTAL MANOMETRY. Manometry of the anal canal is an index of the resistance of sphincters to the passage of faeces. Resting pressure is due mainly to the internal anal sphincter whereas voluntary contraction is due mainly to the external anal sphincter. Anorectal manometry is essential in measuring the length of the anal canal and in establishing the presence of the rectoanal inhibitory reflex. Several techniques are employed to evaluate anorectal manometry which is useful in the investigation of patients with faecal incontinence and constipation. PUDENDAL LATENCIES: Pudendal latencies are valuable in the study of the innervation of the external anal sphincter. Pudendal latencies are measured thanks to the stimulation of the S2-S4 nerves lying in the proximity of the ischial spine through the use of a special glove (St Mark's glove). Prolonged pudendal latencies are typical of neurogenic faecal incontinence but it can be brought about by childbirth, rectal prolapse, obstructed defecation and old age. ELECTROMYOGRAPHY. Electromyography is useful in the study of the function of the pelvic floor. This technique can be performed with single fibre needles which make it possible to measure the action potentials and the fibre density of the muscular fibres. Fibre density is raised in neurogenic faecal incontinence and the action potentials are polyphasic in this condition. Concentric needles are employed to map the anal sphincters and this is useful for evaluating the extent of the damage caused by traumatic events like a third degree tear. ANAL ENDOSONOGRAPHY. Anal ultrasound is very effective in the study of the morphology of the anal sphincters and it requires a rectal probe fitted with a 7-MHz transducer. It is as accurate as electromyography in evaluating the damage to the anal sphincters but it is not painful and it is more acceptable to the patient. DEFECOGRAPHY. This radiological test is a dynamic study of the pelvic floor during defecation. It is very useful for investigating the function and the morphology of the rectum and the pelvic floor during defecation. Important parameters like: the anorectal angle, the opening of the anal canal, the position of the pelvic floor and the descent of the perineum can be evaluated with this test. Defecography is useful in the study of patients with rectal prolapse and constipation. CONCLUSION. All these tests provide extremely useful information on the pelvic floor and are reproducible. They can be of great help in evaluating patients with pelvic floor disorders but they are no substitute for clinical judgement.

Abstract
In this study we evaluated the role of barium examinations and above all computed tomography and magnetic resonance imaging in the study of Crohn's disease. CT is most often requested for patients with suspected or known intraabdominal or pelvic abscesses. MR plays a very important role in the localization of perirectal and perianal abscesses.

Abstract
Twenty-eight consecutive patients submitted to radical nephrectomy for Robson's stage II-III renal cell carcinoma underwent adjuvant recombinant a-2b interferon, 5 MUI s.c. 3 times a week, for 6 consecutive months. Home-feasibility of this therapy resulted easy. The most frequent acute (flu-like syndrome) and late (myalgia, fatigue, anorexia) side effects did not affect normal daily life of patients. Eight (28.5%) patients had WHO grade < or = 2 biochemical and hematological toxicity, that normalized after a reduction or a temporarily suspension of therapy. Twenty-seven patients were evaluable for response. Out of these, 7 (26%) relapsed after a 16 months median follow-up.

Abstract
Until now, patients with a progressive prostatic cancer, in whom all therapies failed and the disease spread locally and distally, was considered "a lost patient"; because it did not exist an effective therapy easily to be used. The skeletal pain control is a serious problem and it is a great responsibility also for the Urologists especially if the patient has not a short survival time and the quality of life is very poor. Physicians feel the need for a systemic, well tolerated and effective therapy also for a long time, uniform and repeatable, able to be efficient for these patients. Strontium 89 chloride seems to offer all these possibilities and to be the best procedure for Urologist, Radiotherapists and Nuclear Specialists in order to satisfy the patients requirements. International research has shown Sr-849 Chloride is a powerful new therapy. Sr-89 Chloride is a radiopharmaceutical product for the treatment of painful metastases from prostatic cancer. It is a new treatment but its effectiveness is well documented and results are reported in the most important international literature. In our Department a clinical research has started and our purpose is to produce more data for a clinical and biological evaluation of the results, hoping that a similar research will extend as a multicenter study.

Abstract
A series of 12 cases of esophageal anastomotic leakage following esophageal surgery observed from 1969 to 1989 is retrospectively analyzed. In the period 1969-1975 6 patients were treated in emergency and the mortality rate was 66.6%, while the remaining 6 patients observed from 1975 to 1989 were treated conservatively with total parenteral nutrition (sometimes associating adequate surgical drainage): the mortality rate was 16.6%. In conclusion, not only in the treatment of anastomotic leakage, but also in its prevention, artificial nutrition has a crucial role. The outcome of thoracic and abdominal fistulas depends mainly on adequate drainage, not necessarily surgical. Cervical fistulas heal in 2-4 weeks, but strictures arise frequently and respond to endoscopic dilatation.

Abstract
During the last 15 years the Dormia stone dislodger has been used in 352 cases (80%) out of 435 of ureteral stones: 318 were at ileo pelvic, 34 at lumbar level. 303 ileo pelvic and 21 lumbar stones have been successfully removed (92%). Considering that the probability of stone removal is directly proportional to the ureteral expansibility and indirectly proportional to the volume of the stone, the Basket technique isn't indicated: When the stone is more than 1 cm.; When the ureter is widely stiff (as in Ormond d. or post-radiotherapy stiffness); When stenosis is present. The impossibility of bypassing the stone, the insufficient expansion of the Basket, the stone irremovability and the difficult extraction through the meatus, my limit the successes of this technique while iperating. The immediate complications have been: 4 sectoral rips of the mucosa surrounding the ureteral end, cured by catheterisation without aftereffects (1.2%); 1 sliding of the ureter through the trigone up to urethral meatus (in a woman), which has been repaired, without aftereffects, by direct catheterisation of the ureter, out of the urethra, after removal of the Basket and stone from the ureteral extremity. (0.3%) Strictures occurred in 5 cases (1.5%) and vescicoureteral reflux in 6 (1.8%). These results of the sole Basket technique (performed according to the well-known directions) seem to be much better than those (which have been illustrated) obtained with the endoscopic lithotripsy.

Abstract
A group of 212 patients operated upon for Crohn's disease were studied and the early postoperative complications with related problems were assessed. The morbidity was 28.3 per cent, 60 patients had at least one complication, mainly of septic nature. The mortality was 3.3 per cent (7 patients), sepsis and deep vein thrombosis with pulmonary embolism were the most common causes of death. Postoperative complications were significantly higher (39.7%) (p less than 0.001) in patients with a pre-operative nutritional deficit and in those who had urgent surgery (44.4%) (p less than 0.001). Among patients with pre-operative sepsis, the morbidity was also higher (34.6%), but was not significant. Peri-anastomotic complications (dehiscence, abscess, fistula, bleeding) were apparently more frequent (45.4%) in patients with histological residual Crohn's disease at macroscopically free resection margins although this contrasts with previous series. A proper pre-operative diagnostic approach, adequate peri-operative protein-caloric repletion, antibiotic therapy, prevention of thromboembolism and elective surgery, are still the primary tools in reducing the morbidity and mortality after surgery for Crohn's disease.

Abstract
A technique that allows a safer use of the pursestring applicator in stapled esophagojejunostomy is described. By means of five stitches, all esophageal layers are incorporated in the stapled line. Thus, missing a segment of esophageal mucosal layer is avoided. No clinical or radiologic leak was observed in 48 patients who underwent total gastrectomy using this technique.

Abstract
From July 1, 1979 to June 30, 1983, 136 consecutive patients from 5 centers in Lombardy entered a prospective randomized study to compare 500 mg. adjuvant medroxyprogesterone acetate 3 times a week for 1 year to no treatment following radical nephrectomy for category M0 renal cancer. After a median followup of 5 years (range 42 to 90 months) 40 of 120 evaluable patients (33.3 per cent) experienced relapse after a median interval free of disease of 17 months (range 2 to 74 months). Relapses occurred in 19 of 58 evaluable patients in the adjuvant treatment group (32.7 per cent) and in 21 of the 62 evaluable controls (33.9 per cent). Sex steroid hormone receptors were studied in 102 of the 120 evaluable patients with the dextran-coated charcoal technique. No significant correlation could be found among receptors, relapses and treatment. On the other hand, 33 (56.9 per cent) of the 58 treated patients experienced 39 complications related to the long-term hormonal therapy. Three patients had to discontinue medroxyprogesterone acetate for severe toxicity after 2 to 3 months. Medroxyprogesterone acetate cannot be recommended as adjuvant therapy to radical nephrectomy in patients with renal cell carcinoma.

Abstract
A combined abdominoperineal approach is described in which not only coloanal anastomosis but also bowel transection were performed through the anus. It is most suitable for cancer located 4 to 6 cm from the anal verge. The main advantages of the technique are precise lines of bowel transection with desired distal clearance of tumor, and easier and safer mobilization of the distal end of the rectum during the abdominal phase of the procedure.

Abstract
From July 1979 to December 1981, 83 patients from 6 centers in the Lombardy underwent radical nephrectomy for category M0 renal cell carcinoma. Postoperatively they were randomly allocated to adjunctive medroxyprogesterone acetate (MPA) or to a control group. After the first year of follow-up, the relapse rate was 13% in the controls (5 of 38 evaluable patients) versus 28% in the MPA treatment group (9 of 32). Sex steroid receptors were studied in both the tumor and in the surrounding healthy parenchyma by the dextran-coated charcoal technique in 52 of 70 clinically evaluable patients. There was no significant correlation between receptor studies and the relapse rate. Besides, receptors were more often detected in the healthy than in the neoplastic tissue, and values rarely exceeded 10 fmol/mg protein. Due to the negative trend in the MPA treatment group, the admittance of patients to this study was stopped after 120 patients had been accepted.

Abstract
The purpose of this study was to evaluate the results of transduodenal papillostomy as a routine procedure in managing choledocholithiasis in treating common bile duct (CBD) stones. From 1973 to 1978, 117 patients underwent transduodenal papillostomy for CBD lithiasis. The operation was carried out in standard manner, and all patients had preoperative telecholangioscopy, cholangiography, and biliary manometry. The mean age of patients was 53.7 years, and women predominated in a ratio of 4.5:1.0. Papillostomy was performed together with cholecystectomy for CBD stones in 111 patients (group 1). In five patients, we had to perform a choledochotomy to remove the stones after an unsuccessful papillostomy (group 2). Eight patients who previously had cholecystectomies underwent papillostomy for retained or recurrent stones (group 3), and three patients had a choledochoduodenostomy for recurrent stones after a previous cholecystectomy and papillostomy (group 4). Complications included two deaths in group 1 (1.9%). No mortality was observed in groups 2 and 4. Moreover, the overall morbidity was due to six cases of wound infection, one case of postoperative bleeding, one case of phlebitis, and three cases of cholangitis. The mean length of hospital stay was 12.9 days, considering all the groups. Lack of confidence with this procedure may explain the different results reported in the literature for transduodenal papillostomy, which on the basis of this study has been shown to ba a valid alternative to supraduodenal choledochotomy in treating CBD stones.

Abstract
The authors compared two groups of patients receiving oral 5% mannitol for bowel preparation to see whether the volume of rectal effluent and quantity of bowel preparation could be maintained by a smaller oral mannitol intake supplemented by an intravenous infusion. Nineteen patients drank 2--3 1 5% mannitol, supplemented by an intravenous infusion of N/saline (intravenous Group) and 19 patients drank 4--5 1 5% mannitol (oral group). The volume of rectal effluent and the quality of bowel preparation was the same in both groups. The loss of sodium in the oral group was corrected by the intravenous infusion, but the infusion resulted in greater water retention. There was no reduction in the incidence of vomiting between the two groups.

Abstract
Human serum albumin microspheres of 1 micrometer diameter labelled with technetium-99 m were evaluated as a model for bacteria in two animal species. Peritoneal lavage recovered comparable amounts of an inoculum of microspheres and simultaneously instilled Escherichia coli. A prospective study was undertaken of 38 patients undergoing elective abdominal operations. Three lavages, each of 500 ml normal saline, were used. Over 80 per cent of the saline was recovered in 37 of the 38 patients with a median of 93 per cent. Recovery of microspheres was assessed from above the spleen, from Morison's pouch and from the pouch of Douglas. There was no difference in the recovery rates from the three sites of placement but significantly fewer microspheres were recovered via a right subcostal incision (median 59 per cent) compared with an upper midline incision (median 91 per cent).

Abstract
Sixty-two patients undergoing colorectal surgery or colonoscopy were prepared by three methods of whole bowel irrigation: nasogastric saline solution alone, nasogastric saline irrigation with oral mannitol, and oral mannitol solution without saline. The additional of mannitol to saline irrigation reduced the risk of sodium and water retention, which was eliminated by oral mannitol alone. The best mechanical preparation was achieved by adding mannitol to saline irrigation, but oral mannitol alone was judged more acceptable by the patients and less demanding by the nursing staff and was the preparation of choice for colonoscopy.

Abstract
The influence of a single peroperative five-liter saline peritoneal lavage has been assessed in 21 consecutive patients undergoing elective operation for colorectal cancer. The aim of the study was to investigate whether reduction in bacterial counts by saline lavage would reduce the incidence of infection and thereby avoid the need for prophylactic antimicrobials. Saline lavage was shown to reduce significantly counts in peritoneal fluid of aerobic bacteria from 2 x 10(4) to 5 x 10(1) (P less than 0.001) and to reduce the counts of anaerobes in peritoneal fluid from 8 x 10(4) to 1 x 10(2) (P less than 0.001). Despite the profound reduction in peritoneal bacterial counts the rate of postoperative sepsis was extremely high; wound infection 47 per cent, intraabdominal abscess 26 per cent and septicemia 13 per cent. These results indicate that saline peritoneal lavage alone is no substitute for short-term antimicrobial prophylaxis.

Abstract
Two hundred and sixteen consecutive patients seen for the first time with symptomatic haemorrhoids entered trials of conservative and minor surgical treatment. They were divided into two groups according to their pretreatment maximal anal pressure. Patients with pressures of 100 cm H2O (73.7 mm Hg) or more (108 patients) were treated by anal dilatation (37), sphincterotomy (34), or high-fibre diet (37). Four and 12 months later anal dilatation had produced significantly better results than sphincterotomy or diet. Furthermore, anal dilatation was the only treatment associated with a significant reduction in anal pressure at four and 12 months. Patients with pressures under 100 cm H2O (108 patients) were treated by rubber-band ligation (35), cryosurgery (36), or diet (37). Four and 12 months later significantly more patients were improved by rubber-band ligation than by cryosurgery or diet. These results suggest that haemorrhoids in patients with excessive activity of the internal anal sphincter are best treated by anal dilatation and that in all other patients rubber-band ligation is the treatment of choice.

Abstract
A prospective randomized trial has compared manual dilatation of the anus (MDA)during general anesthesia with lateral subcutaneous spincterotomy (LSS) during local anesthesia for the management of anal fissure in 156 patients. The two groups were similar with respect to age, sex and symptoms. There was no difference in the duration of time off work or early complications of treatment but, four months after operation, 93 per cent claimed to have been improved by MDA compared with 78 per cent after LSS (P less than 0.05). Recurrent fissure was recorded in 13 patients after LSS (29 per cent) compared with four (10 per cent) after MDA (P less than 0.02). There was a significant reduction in anal pressure at four months (P less than 0.02) after MDA, (123 +/- 31 to 97 +/-33) and LSS (127 +/- 36 to 104 +/- 32), but the anal pressure remained unchanged by operation in all patients where pressures were measured with recurrent fissure. These data indicate that MDA gives better results than LSS for treatment of anal fissure and that successful treatment is associated with a reduction in anal pressure.
