In our country, the treatment by dacryocy­stectomy still exists at many ophthalmic centres. Majority of the cases treated there continue to have epiphora, and unfortuately, a fair number even return back with recurrance of dacryocystitis. Since more than a decade, it has been realised that anastomotic procedures could be the method of choice in few of them also [1],[3],[5] .

During last 5 years the author of this paper has come across as many as 152 such cases with symptoms of epiphora, where dacryocys­tectomy was performed in past in one or the other ophthalmic centre. Out of them, 46 cases showed regurgitation on pressure. All these cases were screened thoroughly and those who were found suitable, were subjected to one of the anastomotic procedures. In this paper an effort is being made to present their method of screening, the surgical technique and their results.


  Material and Method Top


Out of the 152 cases, 146 cases were operated once, 5 cases twice and I case thrice. In all, 3 cases had bilateral involvement. Thus the 155 eyes were examined.

All the eyes were subjected to the following proce­dures to assess if anastomotic surgery was possible.

1. The medial canthus was pressed to study the regurgitation. The presence of regurgitation (Group B) indicated a residual or a pseudo-sac. If the regurgita­tion was through both the puncta (Group B 1 ), it was assumed that both the canaliculi were patent. The preserce of regurgitation through one punctum only (Group B 2 & B 3 ) indicated the patency of that parti­cular canaliculus. The absence of regurgitation (Group A) indicated that perhaps there was no resi­dual sac, or else it was rudimentary without any in­flammation. This finding did not reflect any light on the patency of the canaliculi [Table - 1].

2. Syringing was then performed through the lower punctum in all the cases and in some through the tipper punctum. We carefully noticed the site of re­gurgitation of the fluid. Regurgitation of the fluid through the same purctum indicated blockage in either one or both the canaliculi. Whereas, the regurgitation of fluid through the opposite punctum indicated patency of both the canaliculi. The cases of fistulae showed regurgitation of fluid through the fistulae them­selves but when the fistulur opening was blocked digi­tally, the fluid regurgitated through the puncta. The regurgitation of turbid fluid, however, indicated that there were some exudates in the residual sac [Table - 1].

3. Radiography

i) Plane skiagram of lacrimal bone helped to exclude pathology of the underlying bone.

ii) Dacryocystograms, with 70% Diaginol, de­monstrated well the canaliculi and the resi­dual sac only in group 'B'.

4. Examination of nose and paranasal sinuses was done to exclude nasal pathology.

By above assessment, a total of 51 eyes had residual sac. 54 eyes had upper and 51 had lower canalicular patency [Table - 2]. A total of 56 eyes (36.1%) were declared suitable for surgery, out of which 46 eyes, who had residual sac and patency of lower can­aliculus, for dacryocysto-rhinostomy through residual sac and 5 eyes who had patency of both canaliculi with no residual sac for canaliculo-rhinostomy through com­mon canaliculus. Another 5 eyes, who had residual sac but lower canalicular block were operated for can­aliculo-dacryocystorhinostomy.

[Table - 3] demonstrates age and sex incidence of the above cases operated.


  Surgical Technique Top


The cases were operated preferably under local anaesthesia. Only 3 cases required general anaesthesia.

I. Dacryocystorhinostomy;

The technique of operation of dacryocystorhino­stomy was more or less according to the description of Dupuy-Dutemp's and Bourgeut's. Following modifica­tions were, however, observed.

i) The site of previous scar was slightly on tem­poral side in all the cases. Where the scar was firm and thick, we preferred a seperate incision slightly on nasal side. Where the scar was thin and soft the incision was given at the pre­vious site. In order to save the skin, it was not preferred to include opening of fistulae into the incision.

ii) Dissection was slightly difficult because of dis­torted anatomy, cicatrisation and moderate bleeding. The residual sac was invariably small and sometimes irregular in width. It was narrow in the upper part and almost normal size in the lower part, indicating that in majori­ty, part of funds was excised in previous sittings. It was difficult to cut open the medial wall of the sac. Therefore, a lacrimal probe through the lower canaliculus was passed into the resi­dual sac indenting its medial wall. The medial wall was then cut on the indented part with knife from where the incision was extended with scissors to extreme tipper and lower limits. Now the horizontal incisions were given to make the flaps free.

iii) In none of the cases, the opening in bone was less than 1.5 cm. in diameter. A larger open­ing was preferred to get larger flaps to compen­sate the smaller size of the sac. Stitching of flaps was difficult because at times the sac flaps were just sufficient to pass the stitches.

iv) In cases of fistula, the track was excised and its opening in anterior wall of the sac was closed with catgut stitch.

II. Canaliculo-rhinostomy:

Canaliculo-rhinostomy was performed in 5 cases of Group 'A' where both canaliculi were patent with no residual sac. Since there was no sac, difficulty of stit­ching mucosal flaps was expected. Therefore, during dissection a cut on periosteum along anterior lacrimal crest was made. The periosteum of lacrimal fossa was undermined and reflected laterally. Now, a lacrimal probe was passed through lower canaliculus and in­dentation produced on medial aspect of the periosteum. Over this indentation, a vertical cut was given. This was extended upwards and downwards. Thus, com­mon canaliculus was cut open and small anterior and posterior flaps, were made out of the periosteum. The opening of common canaliculus was dilated with lacri­mal probes and then a 1 mm. size polyethylene tube was passed rhrough lower punctum, canaliculus and newly made opening. This end of the tube was taken out of the nostril through the bony opening. Over the check the two ends of the tube were tied together, the muscosal flaps were stitched to the flaps of the peri­osteum and wound was closed. The tube was left for 2 months and then removed.

III. Canaliculo-dacryocysto-rhinostomy

Canaliculo-dacryocysto-rhinostoty was performed in 5 cases of group B 3 where residual sac was present with lower canalicular block. The technique of opera­tion was the one described by the author. [4]

In the past we used to bandage the eye throughout post-operative phase, but recently we have started giv­ing Tincture Benzoin seal on 2nd or 3rd day of surgery.


  Results Top


The results were assessed by the amount of epiphora, regurgitation, and patency on syring­ing [Table 5]. In present series, a total of 46 eyes (82.1%) showed complete success who neither had epiphora nor regurgitation and the passages were freely patent. 7 eyes (12.5%) had partial success who had occasional epi­phora with no regurgitation. Out of them 5 eyes had partially patent passages. Lastly, 3 eyes (5.4%) had failure in whom neither the epiphora was relieved nor the patency was achieved. One eye even continued regurgita­tion.


  Discussion Top


After dealing with a total of 56 eyes, I have a strong feeling that all the cases of dacro­cystectomy with symptoms of epiphora with or without regurgitation should be properly screened for the possibility of anastomotic sur­gery. Those, who possess some residual or pseudo-sac with both canalicular patency are most suitable cases. Upper canalicular block also showed encouraging results.

Absence of sac with both canalicular patency always posed a problem in stitching the muco­sal flaps. Use of periosteum for this purpose in present series had been ideal.

Tinc Benzoin seal advocated in postopera­tive phase cut short hospitalisation, avoided daily dressings, made the patient comfortable and in cases of dacryocystorhinostomy brought anastomotic channel to function early.

Partial success and failures in this series could be attributed to stricture formation in the newly formed passage in canaliculus or possibly to granulations developing near the opening.

Inspite of this, a large number of eyes (63.9%) who showed absence of sac with both canalicular block, unfortunately, were left. How far conjunctivo-rhinostomy or some other procedure could be tried in them, is yet to be ascertained?


  Summary Top


During last 5 years as many as 152 cases (155, eyes), operated for dacryocystectomy, were screened for possibility of anastomotic surgery to relieve their symptoms. Those who were found suitable were subjected to dacryo­cystorhinostomy, canaliculo-rhinostomy and canaliculo-dacryocysto-rhinostomy. Their re­sults were assessed by the amount of epiphora, regurgitation and patency on syringing. In all, 82.1% had complete success, 12.5% had partial success and 5.4% had failures.

A larger number of the eyes (63.9%) who showed absence of sac with both canalicular block, however, were left over in present study.
