A stop-start first half saw four injury-enforced substitutions in the first 37 minutes.
Southampton lost both centre-backs - Armel Bella-Kotchap and Jan Bednarek - giving them a new pairing of Mohammed Salisu and Ainsley Maitland-Niles, while a tearful Richarlison lasted just five minutes for Spurs, who also had to replace Ben Davies.
Porro wasted two good openings to give Spurs the lead but made no mistake at the third attempt in the first minute of first-half stoppage-time as he hammered in off the crossbar after being picked out by Heung-Min Son.
But Southampton responded immediately after half-time as Walcott teed up Adams, who slid in an equaliser for his 10th goal of the season in all competitions.
Kane restored Spurs' lead in the 65th minute as he powered home a header at the back post from substitute Dejan Kulusevski's deft cross.
