The Compendium of Caraka 8.5: pañcamo 'adhyāyaḥ/

Now we shall explain the success [in treating] complications of the pipe and enema [bag].

Thus spoke the venerable Ātreya.

Now hear about the pipes and enema [bags] that are to be avoided in treatments,
and the complications of a pipe administered by the ignorant, together with their treatments.

Short, long, thin, thick, worn out, loosely bound, / having a hole on the side, and crooked: one should avoid these eight pipes.

Failing to reach, going too far, agitating, scraping, injuring, leaking, / pain in the rectum, and a deviated path are their faults respectively.

Uneven, fleshy, torn, thick, netted, airy, / unctuous, and moist: one should avoid these eight enema [bags] in treatments.

Irregularity of flow, foul smell, leaking, difficulty to hold, oozing, / frothiness, slipping off, and inability to hold would occur from defects of the enema [bag].

Introducing with air, too fast, thrust upward, crooked, jerking, shaking, / inserted too far outside, too slow, and with excessive force are faults of the administrator.

If bound without expelling the air, or if administered entirely to the end, / vāyu, entering and provoked, causes colic and piercing pain.

There, massage, fomentation to the rectum, and vāta-destroying foods [are indicated]. / When [the pipe is] introduced quickly, withdrawn [quickly], or suddenly jerked up,

there would be pain in the hips, rectum, and shanks, stiffness in the bladder, and pain in the thighs; / there, vāta-destroying diet, fats, fomentations, and enemas [are indicated].

When [the pipe is] inserted crookedly, covered by a fold, or closed, the liquid does not pass; / one should withdraw that pipe straight, clean it, and insert it again.

When the pressing is released midway, the air obstructed in the rectum, / becoming strong, would produce pain in the chest and head, and exhaustion of the thighs.

There, an enema with bilva and others, phala, śyāmā and others, along with urine, is [prescribed]. / There would be burning, distress, and swelling when the rectum is injured by shaking [the pipe].

Astringent, sweet, and cooling irrigations along with enemas are [indicated] there. / By a pipe inserted too far, from injury to the [rectal] fold,

there would be discharge of rectal feces accompanied by pain, burning, and piercing ache; / there, ghee, a swab, milk, and a mucilage enema are recommended.

When [pressed] too weakly, it does not suffuse, but if [inserted] too far outside, it returns quickly; / there, fat should again be administered properly by one desiring success.

When pressed excessively, it remains in the gut or reaches up to the throat; / there, an enema, purgation, pressing of the throat, and other procedures [are indicated].

Here is a verse:—

The wise person who knows these faults of the pipe, the enema [bag], and the administrators, / together with their remedies, should perform enema therapies.

Thus ends the fifth chapter, named Success in Treating Complications of the Pipe and Enema [Bag], in the Siddhisthāna of the treatise composed by Agniveśa, redacted by Caraka, and completed by Dṛḍhabala where unavailable.
