11 Which of the following statements is true with regard to the appendix? It is supplied by sympathetic and parasympathetic nerves from the superior mesenteric plexus.It lies behind the caecum in 5% of cases.It comprises taeniae coli similar to the caecum and colon.Options a, b and c are all incorrect.Options a, b and c are all correct.
Laparoscopic Ileocecal Resection
Published in Haribhakti Sanjiv, Laparoscopic Colorectal Surgery, 2020
The terminal ileum is smaller in diameter but has a thicker wall as compared to the cecum and ascending colon. Sometimes, it is very difficult to identify the terminal ileum. In such situation, a distinct ‘fat pad’ present exactly at the terminal ileum may serve as a constant landmark to identify the altered anatomy. Similarly, a distinct strip of taenia coli may help to identify the cecum and ascending colon in difficult terrain. The root of the appendix is exactly at the lower most point of the taenia coli.

The caecum is identified by the presence of taeniae coli and, using a finger or a swab, the caecum is withdrawn. A turgid appendix may be felt at the base of the caecum. Inflammatory adhesions must be gently broken with a finger, which is then hooked around the appendix to deliver it into the wound. The appendix is conveniently controlled using a Babcock or Lane's forceps applied in such a way as to encircle the appendix and yet not damage it. The base of the mesoappendix is clamped in artery forceps, divided and ligated (Figure72.13a). When the mesoappendix is broad, the procedure must be repeated with a second or, rarely, a third artery forceps. The appendix, now completely freed, is crushed near its junction with the caecum in artery forceps, which is removed and reapplied just distal to the crushed portion. An absorbable 2/0 ligature is tied around the crushed portion close to the caecum. The appendix is amputated between the artery forceps and the ligature (Figure72.13b). An absorbable 2/0 or 3/0 purse-string or ‘Z' suture may then be inserted into the caecum about 1.25 cm from the base (Figure72.13c). The stitch should pass through the muscle coat, picking up the taeniae coli. The stump of the appendix is invaginated (Figure72.13d) while the purse-string or 'Z' suture is tied, thus burying the appendix stump. Many surgeons believe invagination of the appendiceal stump is unnecessary.

Case 1: A 9-month male with imperforate anus and a neonatal ileostomy had a Type I pouch colon that was excised. Grossly, the pouch was received as a partially opened cystic structure measuring 9 × 8 × 2.5 cm. The cyst wall (2–3 mm thick) had a 5 cm fistulous tract leading to the bladder. There were no haustrations, tenia coli or appendices epiploicae. The mucosa adjacent to the fistulous opening appeared flattened. External and cut surfaces were congested, no solid areas were identified (Fig. 1A).
